DESCRIPTION OF THE INVENTION
    [002] The present invention relates to a product stacking device for forming product stacks from groups of products in a flat and / or tile-like arrangement, products fed during a transport movement, with at least two stopping means with battery contact areas, which were designed to form product piles.
    [003] A grouping unit is recommended, which is intended to reduce the space between the two stopping means, at least in the battery contact area disposed opposite each other, for at least one pile of products in one direction product groups. Under "product", in this context, preferably, a disc-shaped food, in particular a biscuit, should be understood. But other stackable products can also be imagined. Preferably, the product stacks are provided for packaging a packaging machine, in particular, known to the technician as a hose-type packaging machine and / or roller-type packaging machine and / or box-type packaging machine. Under a disposition of products "arranged in a plane", in this context in particular a provision must be understood, in which the products are transported side by side on a product support, such as a conveyor belt and / or over an area, lying down. Under "stopping means", in this context, in particular, a means must be understood, which is intended to apply through mechanical contact at least one force and / or position on the product or group of products.
    [004] Under a "tile-shaped product arrangement", in this context, in particular, a product arrangement should be understood, in which, with the exception of one last product, products in a tile direction each with a part placed on the next product, where in the tile direction, in the opposite direction, again a next product is placed on the opposite side of the product. The last product in the tile direction can be arranged in the tile arrangement on a product support and / or on a product deposition area. Under a "tile direction", it should preferably be understood in this context a direction parallel to the transport direction, in which the products are tilted vertically in a transport direction. Preferably, the tile direction is identical to the transport direction. In another embodiment of the invention, it is also possible that the tile direction is arranged at an angle, in particular at an angle to the right, in relation to the transport direction. In particular, in an arrangement of tile products, main areas of neighboring products can preferably overlap by more than 10%, with a greater preference by more than 30% and an even greater preference in particular more than 50%. Preferably, main areas of neighboring products are superimposed on an array of tile products by less than 90%, particularly preferably less than 80%. Under "main areas", in this context, in particular, the two largest areas of a product must be understood. Preferably, a tile angle formed by the main areas of the products arranged in tile form and the support of the products, can be 15 °, in particular, preferably, 25 ° to 35 °. All products in a product group can have a tile-like product layout. Alternatively, a last product in a tile direction can be laid flat on the product support and the rest of the products in tile form, where the last product arranged in a tile direction is placed on the last product laid out in a plane . The products in this alternative arrangement are tilted in a direction of transport, preferably the last product in the direction of transport, the products are tilted in opposition to the direction of transport, the first product in the direction of transport, is flat on the support of products. This arrangement, in particular, may be appropriate to form a vertical product stack. Tile product layouts are known to the specialist. Under a "product stack" in this context, in particular, a product arrangement should be understood, in which the main areas of the products are arranged horizontally to the product support and / or in which they form an angle with the horizontal of at least essentially 0 ° or 90 °. Under a "horizontal" should be understood in this context, in particular, a vertical direction in relation to the force of gravity and / or transport direction. At an angle of at least essentially 0 ° there is a stack of products in the horizontal, at an angle of at least essentially 90 °, a stack of products in the vertical. Under "at least essentially", in this context, a deviation of less than 15 °, preferably less than 10 °, in particular, preferably less than 5 °, is to be understood. Preferably, the products of a product stack have an overlap greater than 80%, particularly preferably more than 90%. An overlap of a tile-forming product arrangement can preferably occur continuously. Preferably, the product stacking device is provided for passing fed products arranged in a flat manner from a pile formation to a tile product arrangement. Under a "transport movement" it must be understood in this context, in particular, a movement in a transport direction. Preferably, the transport movement is provided so that the products are transported to another processing step, in particular, transported to a packaging step. The direction of transport can at least change its direction in areas over parts of a continuous transport route, in particular. Preferably, the transport movement is at least in a continuous operational state. Under "continuous" it must be understood in this context, in particular, as free of stops. Preferably, speed changes are stable in the transport movement. Under a "battery contact area", in this context, in particular, a pile formation must be understood as at least one product from a group of products and / or a pile of products that touches the stopping medium. The battery contact area can approach a linear shape and / or a dot shape. Under a "grouping unit", in this context, in particular, a unit should be understood, designed to reduce the space of the battery contact areas acting in the direction of the product groups. The cluster unit may, in particular, have one or multiple mechanical and / or electronic control units, one or multiple bearing units or one or multiple clamping units. In particular, the cluster unit may contain coupled drives and / or rack controls and / or contain sloping areas. Coupled drives, rack controls and / or inclined areas are designed, in particular, to control depending on a position and / or a movement at least another position and / or movement, as in particular, at least one translation and / or a rotation of a stopping means. These devices are known to the specialist. Under a "product group direction" it should be understood in this context, in particular, as an intermediate direction, along which the fed products are arranged in a group of products, next to each other or in tile formation. Under a "space" in the battery contact area in a product group direction, in this context, in particular, a space measured in an intermediate direction of product groups between areas of battery contact areas disposed opposite one should be understood. in relation to the other, which are touched by products of a group of products during the formation of piles when defining the space. The product stack can be formed as a result of an effective displacement of the grouping of a supply of a product arrangement. Continuous cell formation is particularly simple. The transport movement can be uninterrupted. The capacity of the product stacking device can be particularly high. In particular, many piles of products can be formed per unit time. The stack of products can be easily transported during the stacking process, in particular, towards another process step.
    [005] In addition, it is recommended that at least one stopping device be formed by a carrier and / or a counter-support for a feeding device. Under a "feeding device" is to be understood in this context, in particular a device for feeding products and / or product stacks for a packaging machine packaging process. In particular, the feeding device can guide products to an array of products arranged flat and / or in the form of a tile and at the end of the transport route, pass on to the packaging machine as a product stack. In this context, a "drag" must be understood, in particular an element, provided for this purpose, in order to load at least one product or group of products in a transport direction, preferably, push through the power terminal and / or of a shape terminal. Under a "counter-support" should be understood in this context, in particular an element that is provided for this, in order to hold at least one product or group of products against the direction of transport through a power terminal and / or preferably from a shape terminal. In particular, the counter-support can be provided for this purpose, in order to avoid the tipping of products. The trawler and / or the counter support can transport the products and form the product stacks. Construction parts can be saved. The feed device may have a product stacking device. Particularly economical and compact construction may be possible. The feeding device can, in particular, comprise a closed track of a circulating transport system, for example, chain and / or a guide with a closed track. The transport route can, in particular, be part of a transport system route. The skidder and / or counter-support can preferably be mounted in the area of the transport route and movable in the direction of transport. A drive system, in particular, by chain, can be provided in order to drive the drag and / or counter-support along the track. Particularly, preferably, the carriers can and / or the supports be operable at least in part of the transport area, individually by means of a linear motor system. Preferably, the transport system can have at least one primary part of a linear motor system. Preferably, the carriers and / or counter-supports can be mounted on transport elements, the secondary parts of a linear motor system can have, in particular, permanent magnets. The drag and counter support can, in particular, be moved flexibly. In particular, spaces between the drag and the counter-support can be variable. Spaces between stopping means can be flexibly adjusted. Length of product stacks and / or product groups can be easily adjusted. Piles of products each with different lengths and / or each with a different quantity of products can be formed.
    [006] In addition, at least one storage unit is recommended, through which at least one of the stopping means is mounted and capable of turning in at least a degree of freedom. In particular, the storage unit can be part of the grouping unit. The space between two stopping means of battery contact areas disposed opposite each other, can be effectively reduced by rotating at least one stopping means. Preferably, the stopping means can be mounted rotatable about an axis, which is at least essentially transverse, that is, at an angle of 90 °, to be relatively mounted in a product group direction. Under "at least essentially", in this context, a deviation of less than 30 °, preferably less than 10 °, in particular preferably less than 5 ° is to be understood. The bearing unit can arrange rotatable stop means on the means of transport such as a chain and / or transport elements of the supply device. The space in the direction of the product groups of the battery contact areas opposite to each other, between one mounted on the feeding device, in particular, formed as a entrainer, stop means and arranged stop means capable of turning, can be efficiently reduced. A swiveling stop means provided can effectively influence a tile angle of a tile-shaped product arrangement and exceed an angle of a product stack. At least two stopping means can be advantageous, in particular a entrainer and a counter-support that are provided to form a pile of products, available that can be rotated in a bearing unit. A tile angle and a space of battery contact areas can be regulated efficiently. The formation of product piles can particularly protect the product. In another embodiment of the invention, it is possible that other rotating stopping means are available in at least one bearing unit. The other bearing unit can preferably be mounted on a feeding device in the opposite direction to gravity from the opposite side of the product group. Other arrangements for storing other stopping means are also possible. The other stopping means can efficiently sustain the formation of product piles. Mobile counter-supports along the feeding direction of a food device can be discarded.
    [007] In addition, it is recommended at least one bearing unit, on which at least one of the stopping means, at least along a working section, is arranged at least mobile in translation in a certain degree of freedom. In particular, the bearing unit can be part of a grouping unit. The space between contact areas of opposing cells in relation to each other by two stop means can be reduced efficiently by the translation movement of at least one stop means essentially towards the product group.
    [008] In addition, at least one drive unit is recommended, with which at least one stopping means can be operable in at least one degree of freedom. In particular, the drive unit may have an actuator such as a rotating cylinder, a stepper motor and / or in particular a servo drive and / or contain a slide distribution. A control unit of the grouping unit provided for this, in such a way that a movement of the stopping means is controlled and / or regulated to a certain degree of freedom. The degree of freedom can be in particular, a rotation or a translation. The control unit can efficiently adjust the space between the contact area of opposite batteries in relation to each other by two stopping means.
    [009] In addition, it is recommended that the grouping and feeding unit be provided so that it forms at least one pile of products by controlling at least one drive unit. In particular, the grouping unit can reduce, through adequate control of at least one drive unit, the space between contact areas of opposite batteries in relation to each other towards the product group, so that a product group and pushed next to a pile of products. Upon reaching a desired stack length, the grouping unit can at least essentially keep the space between battery contact areas opposite to one another in the direction of product groups. Preferably, force measuring devices can be provided that would signal an increase in force caused by the product stack between the stop means when the product stack length is reached and / or exceeded. The force measuring devices can be arranged in the stop means and / or in the means of depositing the stop means. Preferably, the drive sizes of the drive units of the stop means can be used to determine a force, in particular drive flows and / or drive moment and / or drive forces. In particular, the formation of protective and flexible batteries may be possible.
    [0010] In addition, it is recommended that at least one stop means have battery contact areas in two directions of product groups disposed opposite each other. In particular, piles of products can be formed each between directions of groups of products sequentially to the stop means. A stopping means can simultaneously form a product deposition area from a product stack and still further a product deposition area and another product deposition area from a product group direction neighboring the product stack. The amount of stopping means can be reduced. The product stacking device can be particularly compact and economical.
    [0011] In addition, it is recommended that the grouping unit includes at least one slide distribution. The slide distribution can, in particular, be mounted on the product stacking device and / or locally, on the rack of the feeding device. Slide distribution can be provided to move or tilt the stopping device depending on the position. The formation of batteries as it is mechanically controlled, in particular, depending on a position of the product groups and / or the stopping means along the transport route. In addition, in particular, servomotors and / or linear motors can be discarded to control the formation of batteries. The product stacking device can be particularly economical.
    [0012] In addition, it is suggested that the cluster unit should include at least one electrical control unit and / or one electronic control unit. The electronic control unit, preferably, was designed to control and / or regulate the spaces individually of the means of stopping battery contact areas in the direction of groups of products opposite each other. The formation of piles can be particularly flexible. Different stack lengths may be possible. In particular, mechanical adjustment and / or a change in the product stacking device to form product piles of different lengths can be discarded.
    [0013] In an alternative embodiment of the invention, it is recommended that the grouping unit includes at least one means of stopping a lateral driving guide positioned at an angle in relation to the transport movement. Preferably, the grouping unit includes at least two stopping means formed in the direction of the product groups, disposed opposite to each other, with side guides positioned at an angle, so that the space towards the product groups of the areas of deposition of products disposed opposite each other in the direction of the transport movement is reduced. Preferably, the transport movement is at least essentially transversal in relation to the direction of product groups. Preferably, a pile formation occurs, at least in the main, by reducing the length of the product groups across the transport area. Under "at least essentially" it should be understood in this particular context as a deviation less than 30 °, preferably less than 15 °, particularly preferably less than 5 °.
    [0014] Preferably, the groups of products are guided through the movement of transport through the contact areas of batteries in such a way as to be grouped, in view of the reduction of their space in the direction of transport. Preferably, the space of the side feed guides with each other and the angle of the skewed position in relation to the direction of product groups and / or the transport movement are adjustable with the aid of an appropriate adjustable storage device of the side guides. of batteries can occur through a static arrangement of elements of the cluster unit. The grouping unit can be particularly simple. A control and / or regulation of movements and / or drives for the formation of batteries can be discarded. Between the stopping means a large number of product piles can be formed sequentially and continuously. The product stacking unit can be particularly capable. The side guides can be provided as abutment strips. Preferably, the side guides contain circulating straps and / or tracks. Friction between product groups and side guides can be minimized. Product piles can be formed protected.
    [0015] In a variant of the invention it is suggested that at least one of the stopping means be provided to move the product groups away from the fed products. In particular, the stopping means can be conducted between two groups of products followed by fed products arranged in a plane and / or in tile formation. The product groups can be separated from the stopping means and separated by the stopping means. The product group is made up of a number of products, which must form a stack of products. The product groups arranged in a flat product layout and / or fed product tile formation can be guided to the product stacking device, without the product groups being already apart. A separate device for separating product groups can be discarded. Preferably, the groups of products can be moved apart by dragging the product stacking device. Trawlers can be advantageously driven between product groups in order to spread and create product piles, where trawlers push product groups in the transport movement against each counter. The product stacking device can efficiently separate product groups in particular and form product stacks.
    [0016] In yet another variant of the invention, an entrance mat is recommended, which is intended to, at least, in a first stage of the formation of a pile of products, force the groups of products deposited on the entrance mat with the transport movement against the slowest stopping means in relation to the transport movement. Preferably the fed products, arranged in a plane and / or in a tile-shaped product arrangement, are deposited on the entrance conveyor and / or transported from the entrance conveyor according to the transport movement. Preferably, the entrance mat opens a window, through which a stop means protrudes. The entrance mat can, in particular, be formed by two parallel mats, and between it there is a window through which the stop means protrudes. Products can preferably be routed from a feed conveyor individually to the inlet conveyor. The stopping means can be formed as a counter-support and move more slowly in relation to the movement of the conveyor belt. The products will be forced against the counter-support and will form a tile-like product arrangement. Due to a faster movement of the entrance mat in relation to the counter-support, the tile angle of the product layout during transport is accentuated. The second stop means is advantageously formed as a entrainer and forms a second stage of the product stack by reducing the space of the battery contact areas of the stop means towards groups of products arranged opposite one another. The inlet mat can advantageously support the formation of product piles. In particular, the first stage of product stack formation through the inlet mat can favorably protect the product. Damage to products can be avoided.
    [0017] In addition, a method is recommended for forming at least one stack of products horizontally or vertically with a product stacking device described. Two means of stopping can by reducing the space in the direction of the product groups of the contact areas of cells disposed opposite each other, to quickly and efficiently push groups of products arranged in the form of a tile, bringing together a pile of products. To form a stack of products vertically, in particular, a first or last product in the product group can be arranged in a product configuration in a flat form. Other products can be arranged in a product configuration in a tile formation, where the next product is superimposed on the product laid out in the plane. In reducing the space of the battery contact areas, products can be guided to a vertical product stack. For forming a stack of products horizontally, all products, in particular, from a group of products are arranged in an arrangement of products in tile formation. By reducing the space of the stack contact areas, the tile angle can be increased until the arrangement of products forming a tile becomes a horizontal product stack. It is possible that a pile formation is quick and simple. The formation of the pile can occur in a continuous movement, in particular, together with the transport movement.
    [0018] In addition, a feeding device is recommended, in particular, for feeding products in relation to a packaging process, with the product stacking device. In particular, the product stacking device can be integrated into the feed device. The transport elements of the feed device can form the stop means of the product stacking device. Construction parts may be discarded. A particularly compact construction of a feeding device is possible with the product stacking device. A particular feeding device can be part of a packaging machine, the packaging machine can have the mentioned benefits. GRAPHICS

    [0032] Figure 1 shows a product stacking device 10a for forming product stacks 12a of product groups 14a of product 16a arranged flatly fed during a transport movement 28a with stop means 18a with contact areas piles 20a, which are provided for the formation of product piles. The product stacking device 10a has a feed unit 22a, which is designed to form a product stack 12a by reducing the gap 24a of the battery contact areas 20a disposed opposite each other in a direction of product groups 26a with two stop means 18a. The product stacking device 10a is part of a feeding device 34a of a packaging machine 110a (Figure 10). In the illustrated example, a product path 16a feeds the product stacking device 10a. In an improvement of the modality shown here, a multi-path modality is also possible, in which more paths of products 16a are fed side by side, to form more stacks of products 12a side by side. Thus the stop means can simultaneously form more stacks of products 12a mounted side by side or more stop means 18a can be provided side by side.
    [0033] Products 16a are routed flat on a feed conveyor 58a in a feed direction 60a over an inlet conveyor 62a. Thus product groups 14a are formed in a tile-like product arrangement 64a. The stop means 18a are formed with the carriers 30a and counter-supports 32a of the feeding device 34a. The carriers 30a and the counter-supports 32a are arranged in a circulating chain 66 and are moved along a conveyor path 68a in a transport direction 70a. The feeding mat 58a can be formed as a so-called telescopic mat (Pull-Nose), in which one end of the mat 72a is movable in the feeding direction 60a, to facilitate the formation of windows between the product groups 14a. The specialist is aware of several solutions in this regard.
    [0034] Traps 30a are used to push the product groups 14a arranged on a product support 74a in a transport direction 70a towards a packaging machine, not detailed here, at the end of the transport route 68a. Traps 30a are mounted on chain 66a in a vertical direction relative to transport direction 70a, so that the trawlers can be lowered into the feed belt area 58a via slide distribution, not detailed here, under the product support 74a by means of a tilting movement. After a product group 14a with a desired quantity of products 16a has been formed, the entrainer 30a is aligned, so that the entrainer can be transported, with respect to the gravity force 76a, through a shape terminal, the product groups 14a arranged on product support 14a. Product group 14a is primarily in the arrangement of tile-shaped products 64a, which forms in relation to the direction of transport 70a parallel to the direction of product groups 26a a tile angle 78a between the main areas 106a of products 16a and the 74a product support less than 45 °. Counter supports 32a are provided to support product groups 74a arranged on product support 74a against transport direction 70a. Traps 30a and counter-supports 32a form the stopping means 18a of the product stacking device 10a and touch the product groups 14a with battery contact areas 20a.
    [0035] The bearing units 36a house the stop means 18a formed with counter-support 32a that can be rotated at a degree of freedom 38a in the chain 66a. Product support 74a has a bearing unit 40a, which houses the stopping means 18a along a corresponding working section 42a of a transport path 68a at a degree of freedom 44a along the transport direction 70a being able to move in translation. A drive unit 46a drives the chain 66a. The stop means 18a formed as entrainers 30a are driven in translation in a certain degree of freedom 44a in the direction of transport. A slide distribution 52a moves based on the movement of the drive unit 46a, in tilting movement 80a at a degree of freedom 38a the stop means 18a formed as counter-support 32a.
    [0036] Stop means 18a with slide distribution 52a and bearing units 36a and 40a are part of grouping unit 22a. The tilting movement 80a causes a reduction in the space 24a of the battery contact areas 20a opposite each other in the direction of product groups 26a of the carrier 30a and the counter support 32a. The product groups 14a are aligned starting from an array of tile products 64a to a horizontal product stack 12a. The carriers 30a and counter-supports 32a are now moved in sync with the transport direction 70a and at the end of the transport path 68a pass the product stack 12a for a packaging machine packaging process. In the variant, not detailed here, the counter-supports 32a mounted relative to the chain 66a are additionally movable in translation in the transport direction 70a against a spring force or through a controllable or adjustable drive. A product stack length 90a can thus be adjusted additionally.
    [0037] The description below and the drawings of other example modalities are essentially limited to the differences between the example modalities, where in reference to components of the same denomination they can basically also be referenced in drawings and / or in the description of other examples of modalities. To differentiate the modality examples, the letters b through k are substituted for the letter a of the first modality example in the other modalities examples.
    [0038] Figure 2 shows a product stacking device 10b for forming product stacks 12b from product groups 14b of fed products arranged flat during a transport movement 28b with stop means 18b with stack contact areas 20b, which are provided for the formation of product piles 12b, in a second example of modality.
    [0039] The product stacking device 10b differs from the first example of embodiment, in particular, in that the carrier 30b and the counter-support 32b of a feeding device 34 b forming stop means 18b which are mounted on elements conveyor 82b, which are operable through a drive unit 46b formed by a linear motor system 84b, with individual position and speed regulation. The transport elements 82b contain each secondary part 86b of the linear motor system 84b. Instead of a chain, the feeding device 34b contains a controllable individual electromagnet, mounted along a track circulating to a primary part 88b. An electronic control unit 54b independently regulates the position and speed of transport elements 82b. The control unit 54b forms a grouping unit 22b with the linear motor system 84b and the transport elements 82b with the stop means 18b. The control unit 54b controls the position and speed of the stop means 18b during the transport movement 28b for a packaging process in such a way as to reduce a space 24b of battery contact areas 20b by at least two stop means 18b in a direction of product groups 26b. Thus, the supports 32b through the bearing units 36b can be rotatable in a degree of freedom 38b mounted on the transport elements 82b. A tilting motion 80b is controlled via slide distribution 52b depending on the position along a conveyor path 68b. The space 24b is determined by overlapping the tilting movement 80b as well as regulated by the control unit 54b through the relative positions of the stop means 18b with each other. By combining the tilting movement 80b with a translation of the stopping means 18b in the direction of transport 70b, the product group 14b can be aligned from a tile-like arrangement of products to a horizontal product stack. The stack lengths of different products 90b can be adjusted via the control unit 54b without a change in mechanical shape or a change in the product stacking device 10b. It is also possible that in a transport direction 70b of product stacks that follow one after the other have different lengths of product stacks 90b.
    [0040] Figure 3 shows a product stacking device 10c for forming product stacks 12c of product groups 14c of fed products 16c arranged flat during a transport movement 28c with stop means 18c with contact areas of stacks 20c, which are provided for the formation of stacks of products 12c, in a third example of modality. The product stacking device 10c differs from the first example of embodiment, in particular, in that the carrier 30c and the counter-support 32c of a feeding device 34c in bearing units 36c are mounted on a chain and are liable to turning to a degree of freedom 38c. The movement by the degree of freedom 38c of the entrainer 30c and the counter-support 32c is controlled through slide distribution 52c. Trap 30c, counter support 32c and slide distribution 52c are part of a grouping unit 22c. A tile angle 78c of the product groups 14c is influenced by the counter supports 32c. The counter-supports 32c align along a transport path 68c during the formation of product stacks with reference to the force of gravity 76c, so that the tile angle 78c increases. The conveyors 30c are equally aligned along the conveyor path 68c, until the conveyor 30c and the counter-support 32c are vertically in relation to a conveyor device 70c. A space 24c between contact areas of piles 20c opposite to each other in a direction of product groups 26c of stop means 18c formed as carrier 30c and counter support 32c is reduced in such a way that piles of horizontal products are formed 12c. The stacks of products 12c are formed in particular protected by the simultaneous alignment of the draggers 30c and counter supports 32c.
    [0041] Figure 4 shows a product stacking device 10d for forming product stacks 12d of product groups 14d of products 16d arranged in an array of tile forming products 64d fed during a transport movement 28d with means of stop 18d with battery contact areas 20d, which are provided for the formation of product batteries 12d, in a fourth example of modality.
    [0042] The product stacking device 10d differs from the second example of modality, in particular, in that the drag 30d and the counter-support 32d form the stopping means 18d for a reduction of the space 24d of contact areas of stacks 20d opposite each other in a direction of product groups 26d in a translation overlap of the transport movement 28b and / or move against a transport direction 70b. The drag 30d and a counter support 32d are part of a grouping unit 22d. A bearing unit, which allows a tilting movement, can be discarded. Construction is particularly simple and economical.
    [0043] Figure 5 shows a product stacking device 10e for forming stacks of products 12e from product groups 14e of products 16e arranged flatly fed during a transport movement 28e with stop means 18e with contact areas of stacks 20e, which are provided for the formation of stacks of 12e products, in a fifth example of modality.
    [0044] The product stacking device 10e differs from the second example of modality in particular, in that the stop means 18e of the battery contact areas 20e have two sides 48e, 50e opposite each other in one direction of product groups 26e. The product stacking device 10e is designed for forming product stacks 12e vertically. A stop means 18e simultaneously assumes the function of a carrier 30e of a group of products 14e and a counter-support 32e in a transport direction 70e contrary to the groups of products 14e that follow. A number of stop means 18e is reduced in relation to the previous example embodiments.
    [0045] Prior to the formation of the pile, the last product 102e fed and laid flat in product group 14e is arranged in transport direction 70e on an inlet conveyor 62e, while other products 104e in product group 14e are arranged in a 64e tile product layout. The other products in the 104e tile position are supported directly or indirectly on the last 102e products. By reducing the gap 24e of the battery contact areas 20e opposite each other in the direction of product groups, the other products are pushed over the last 102e to form a stack of products 12e vertically. The stop means 18e driven through a drive unit 46e with a control unit by means of a position and speed control of the stop means 18e, where the control unit 54e belongs to a cluster unit 22e. The drive unit 46e is formed as in the second example embodiment, as a linear motor system 84e and an individual drive of the stop means 18e.
    [0046] Figure 6 shows a product stacking device 10f for forming product stacks 12f of product groups 14f of products 16f arranged flatly fed during a transport movement 28f with stop means 18f with contact areas of stacks 20f, which are provided for the formation of stacks of 12f products, in a sixth example of modality.
    [0047] The product stacking device 10f differs from the fifth example of modality, in particular, in that the stop means 18f mounted to the bearing unit 36f are capable of turning on the transport elements 82f. The formation of piles of 12f products is supported by an additional tilting movement 80f and is protected in particular. The tilting movement 80f is controlled by a slide distribution 52f depending on a position of the stop means 18f along the transport track 68f. A linear motor system serves for independent control and regulation of speed and position of the stop means 18f via a control unit 54f. The stop means 18f, the slide distribution 52f, the bearing units 36f and a drive unit 46f formed as a linear motor system 84f are part of a cluster unit 22f. At the final end of the transport route 68f the product piles 12f are enveloped by means of a foil hose, in a packaging process of a 110f packaging machine, from the foil hose 108f are formed through a sealing unit, not detailed here, individual packages each with a stack of 12f products.
    [0048] Figure 7 shows a 10g product stacking device for forming product piles 12g of product groups 14g of 16g products arranged flatly fed during a transport movement 28g with stop means 18g with contact areas of 20g batteries, which are provided for the formation of 12g product batteries, in a sixth example of modality.
    [0049] The product stacking device 10g differs from the first example of modality, in particular, in that the stopping means 18g formed as counter-support 32g capable of turning mounted to the bearing unit, in which the bearing unit 36g according to the present example is mounted against the gravity force 76g above the product groups 14g. It is also possible to think of an alternative formation, that at least one bearing unit with stop means related to the movement of transport 28g next to or in relation to the force of gravity 76g mounted under the product groups 14g. The stop means 18g are mounted on a wheel 92g, which is mounted on the bearing unit 36g which can be rotated about a rotary axis 94g. The stop means 18g formed as entrainers 30g push the product groups 14g in a transport direction 70g against one of the counter supports 32g. The 32g counter-support is now vertically downwards, in the direction of the 76g gravity force. A gap of 24g between contact areas of 20g batteries opposite each other in the direction of product groups 26g, the counter support 32g and the carrier 30g is reduced, so that from product groups 14g a product stack is formed 14g. Subsequently, the counter-support 32g is removed by a bearing unit 36g from the product stack 12g by a tilting movement, so that the entrainer 30g can transport the stack of products 12g under the counter-support 32g through the direction of the shipping 70g. Then, the next 32g counter-support is directed vertically down the formation area of a next 12g product stack. In the example shown, four countermounts 32g are mounted on the wheel 92g, where each two disposed opposite one another from the other countermounts 32g are driven together. The counter supports 32g followed around the wheel 92g are driven independently, so that the counter supports 32g of two groups of products followed 14g can be synchronized independently of each other with the groups of products 14g. The movement of the dragger 30g driven by a circulating 66g chain and the counter support 32g is determined through the control unit 54g. The stop means 18g and the control unit 54g are part of a cluster unit 22g.
    [0050] Figure 8 shows a product stacking device 10h for forming product stacks 12h of product groups 14h of products 16h arranged flatly fed during a transport movement 28h with means of stop 18h with contact areas of 20h batteries, which are provided for the formation of 12h product batteries, in an eighth example of modality.
    [0051] The 10h product stacking device differs from the first example of modality, in particular, by the fact that a tile angle 78h of a disposition of products 64h, in tile formation, produced from fed products arranged flat, guaranteed by 96h backing wedges, it is mounted in a 70h transport direction from one side used by the 18h stopping means as a 30h drag. A 18h stop means produced as a support element 98h supports at the end of a group of products 14h in the direction of transport 70h, the next group of products placed on the backing wedge 96 (Figure 8-I). The crawler 30h with the backing wedges 96h and the support element 98h are part of a grouping unit 22h. The 96h backing wedge is moved in a 70h transport direction along with the next 12h product stack, in the 70h transport direction. The 12h product group is moved through the next 30h carrier also in the direction of transport 70h against the support element 98h, so that the 24h space between the 20h product deposition areas of the support elements 98h and the 30h carrier is reduced and the 14h product group aligned (Figures 8 to 11). A 32h counter support mounted on a 34h feeding device, on a 36h bearing unit and tilting to a degree of freedom is tilted against the 14h product group and aligns the 12h product stack by reducing the 24h space of the areas of contact of batteries 20h opposite each other, of the counter-support 32h and of the entrainer 30h, until a pile of 12h products is formed. The support element 98h is pushed upwards against the gravity force 76h of a product support 74h and the product stack 12h (Figures 8 to 11). The 30h haulers and the 32h counter-supports carry the 12h product stacks together towards a packaging process.
    [0052] Figure 9 shows a product stacking device 10i for forming product stacks 12i of product groups 14i of products 16i arranged in an array of tile forming products 64i fed during a transport movement 28i with means of stop 18i with contact areas for batteries 20i, which are provided for the formation of piles of 12i products, in a ninth example of modality.
    [0053] The cluster unit 22i contains two stopping means 18i as side guides 56i with circulating conveyor belts and a feeding device 34i with a transverse chain 100i. Product groups 14 are transported with a transverse chain 100i in a direction of product groups 26i transverse to a transport direction 70i. One of the side guides 56i is arranged at an angle in relation to the transport movement 28i mounted on the feeding device 34i so that, in the feeding direction 60i, the space between the battery contact areas 20i in the direction of product groups 26i is reduced, while the other side guide 56i is mounted parallel to the feed direction 34i. Based on a reduction in space 24i the product groups 14i are grouped in a stack of products 12i horizontally during transport in the direction of transport 70i.
    [0054] Figure 11 shows a product stacking device 10j for forming stacks of products 12j, of product groups 14j of products 16j arranged flat, fed during a transport movement 28j through a grouping unit 22j, with means stop 18j, with contact areas of piles 20j, which are provided for the formation of piles of products 12j, by reducing a space 24j of contact areas of piles 20j in a direction of groups of products, in a tenth example of modality. The product stacking device 10j differs from the first example of embodiment, in particular, in that the stop means 18j formed as entrainer 30j is designed to separate the product groups 14j from the fed products 16j. Stop means 18j can be driven, for example, by a circulating current or by a linear motor system. The product stacking device 10j of this example embodiment is provided for forming horizontal stacks of products 12j. It would also be possible to apply the particular characteristics of this example of modality to a product stacking device for forming product vertical stacks. Products 16j are conveyed to an inlet conveyor 62j, arranged flat on a conveyor belt 58j in a feed direction 60j. The feeding mat 58j is formed as a double mat with two parallel mats, which have a space. After a number of products 16j, which must form a pile of products 12j, each of the entrainers 30j will be guided between two products arranged on the feeding belt 58j and should therefore separate two groups of products 14j in a row. To drive draggers 30j between products 16j, they are mounted using bearing units 36j that can be rotated at a degree of freedom 38j and are controlled in such a way through a slide distribution 52j, that the draggers are aligned in one place each, to which they must be guided between the products 16j, vertically in relation to the transport movement 28j. As an alternative to the 52j slide distribution, a servomotor control could also be provided, for example. A formation of windows between the product groups 14j through a formed medium separate from the grouping unit 22j, such as a telescopic mat, as in the first example of embodiment, can thus be discarded. Then, each space between the battery contact areas 20j of the carriers 30j and a second stop means 18j formed as a counter-support 32j, is reduced to form the product stack 12j. To achieve this, the mounted rotatable counter-supports 32j can be tilted by the slide distribution 52j against the transport movement 28j, against the carriers 30j.
    [0055] Figure 12 shows a 10k product stacking device for forming stacks of 12k products from product groups 14k of 16k products arranged flatly fed during a 28k transport movement through a 22k bundling unit with means of 18k stop with 20k battery contact areas, which are provided for in an eleventh example of modality. The 10k product stacking device of this example modality is provided for the horizontal formation of 12k product stacks. It would also be possible to make appropriate use of the characteristics, in particular, of this example of modality for a product stacking device for forming vertical product stacks. The 10k product stacking device differs from the first example of modality, in particular, in that a 62k inlet mat is provided in the first stage of the formation of 12k product stacks, in which the 14k product groups arranged on the Inlet conveyors 62k with the transport movement 28k slower than the transport movement 28k, are forced against the stop means 18k formed as counter supports 32k. The stop means 18k can be operated, for example, by means of a circulating current or a linear motor system. The 16k products, in a flat layout, are routed through a 58k feed conveyor to a 60k feed direction over the 62k inlet conveyor. The inlet mat 62k is formed as a double mat with two mats in parallel, which have a space, so that the stop means 18k can be conducted in the area of space through the inlet mat 62k. The stopping means 18k are mounted vertically rotating with a degree of freedom 38k with respect to the movement of transport 28k and controlled through a distribution by slide 52k, formed as drag 30k and counter-support 32k. As an alternative to the 52k slide distribution, a servo motor control could also be provided, for example. The counter-supports 32k, in a first stage I are inclined towards the transport movement 28k and move towards the transport movement 28k more slowly than the inlet conveyor 62k, so that the products 16k are sent to the conveyor 62k entrance through the 58k feeding mat, of each 14k product group and forced against a 32k counter-support and form a 64k tile product arrangement. Through the speed difference between the 62k inlet mat and the 32k counter-support, a 78k tile angle of the 14k product groups becomes more skewed. In a step II, the counter-supports 32k are positioned vertically in relation to the movement of transport 28k and the draggers 30k through the direction arranged opposite to the movement of transport 28k at the end of each product group 14k. In a step III, the draggers 30k are directed vertically to the transport movement 28k and thus by reducing the space 24k of the contact areas of batteries 20k disposed opposite each other in a direction of product groups 26k from the loaded 30k and of the 32k counter-supports the product stack is formed. The skidder 30k and the counter-supports 32k now move synchronously towards the transport movement 28k, to continue transporting the 12k product stack.
