    25 30 35 534 139 2 means that the cutlery parts only adhere pointwise to the magnets, which means that the adhesive surface is very small and that there is thereby a great danger of an undesired release of individual cutlery parts which could only be overcome by the magnets exhibiting a significant field strength. However, if the magnetic force is increased, in these circumstances the consequence is that the cutlery parts no longer align under the influence of gravity but adhere in any position on the transport device.
    For sorting the cutlery parts, it is further proposed in the document EP 0 213 100 B1 to arrange other separate magnets under the transport device, each of which is at a distance from the transport device which corresponds to the specific length of each cutlery part. The cutlery parts suspended from the transport device are guided over these separate magnets so that the cutlery parts can be separated from the holding device by the magnetic attraction of the separate magnets. After detachment from the transport device, the cutlery parts fall into containers arranged for this purpose. A plant of this kind thereby has additional disadvantages. For example, a cut-off of the cutlery parts must constantly take place inside the feeding device so that only one cutlery part at a time can be picked up by the magnets of the pouring device. Due to the only punctual adhesion between the cutlery part and the magnet, the pouring force of the magnets must be dimensioned so that during the circulation no independent detachment of the cutlery parts can take place.
    The cut-off of the cutlery parts by the additional magnets which are arranged correspondingly in the length of the cutlery parts must take place with a magnetic force which is greater than that of the holder magnets. Thereby, there may also be a danger that the cutlery parts do not become detached from these separation magnets and consequently do not fall into the arranged containers without several cutlery parts remaining adhered to one of these magnets.
    In this way, however, a disturbance-free operation of the plant would be negatively affected or prevented. In addition, cutlery parts such as forks and tablespoons have practically identical lengths, which makes it almost impossible to distinguish between these cutlery parts by a sorting that takes place through the distance and one can expect a high error rate when sorting.
    The object of the invention is to propose a method for sorting various ferromagnetic cutlery parts which is easy to perform, which works continuously and without interruption and which makes further manual operations indispensable, in which case in particular the adhesion of the cutlery and their transfer from the holding device to a subsequent processing unit can be optimized. .
    Furthermore, a device is proposed for carrying out this method, which is constructed as simple and as compact as possible.
    Its purposes are achieved through the features of the main claims. the invention is apparent from the respective subclaims attached thereto.
    In this method for sorting various ferromagnetic cutlery parts, these cutlery parts are first fed through a feeding device of a pouring device, wherein Embodiments of the holding device have a transport device which can rotate about at least one axis of rotation, the transport device comprising a surface which is equipped with several magnets for adhering the cutlery parts. After the adhesion of each individual cutlery part to a magnet, the transfer of each cutlery part to a subsequent one takes place by a continuous increase of the distance between the magnet and the cutlery part.
    With the aid of the method according to the invention, cutlery parts which are dispensed in large quantities, which are cleaned and which are made unsorted available can be easily separated and then sorted. The procedure works very reliably and can be performed in a simple way. In particular, the possibility of a continuous and interference-free operation constitutes a decisive advantage compared with known designs. Manual intervention becomes unnecessary. A very significant advantage is also achieved by the uniform and harmonious transfer of the cutlery parts from the holding device to the identification unit, which transfer takes place continuously through said increased distance between the magnets and the cutlery part, whereby an optimization of the transport and the identification of the cutlery parts is achieved.
    The cutlery parts no longer need to be pulled off the magnets of the holding device. Coupling procedures are also omitted, which are otherwise required for controlling one of the electromagnets which effect the adhesion of the cutlery parts, as well as the control or regulation technique necessary for this purpose.
    According to a first embodiment of the method according to the invention, it is proposed that the alignment of the cutlery parts on the holding device takes place while utilizing gravity.
    This feature, which is known per se from the state of the art, has been further developed according to the invention so that the cutlery, through the rotation of the transport device about its axis of rotation, aligns due to the action of gravity and thereby abuts independently and uniformly against the holder device surface. In this respect, the magnets pick up the cutlery parts not only punctually, but with their entire effective surface, whereby the adhesion has been able to be significantly improved. The transport of the cutlery parts was further improved by this solution in that, in addition to the adhesive force of the magnets, an additional holding force resulting from the holding friction was utilized, which results in the cutlery parts abutting against the surface of the transport device. Thereby an independent and undesired unloading of the cutlery parts from the transport device can be avoided in a safe manner.
    Due to the further alignment of the cutlery parts due to gravity, these can be transferred to the identification unit in an aligned manner.
    A further improvement of the embodiment of the method according to the invention is obtained by the feeding device feeding the cutlery parts to the holding device already aligned.
    As a result, the cutlery parts are quickly picked up through the holding device so that the pace is reduced, ie more cutlery parts can be added for sorting per unit of time.
    In addition, in order to achieve a reliable picking up of the cutlery parts through the holding device, it is helpful if the feeding device feeds the cutlery parts 10 15 20 25 30 35 534 139 4 one by one to the holding device. Thereby it is possible to optimize the adhesion of individual cutlery parts to the magnets of the transport device arranged for this purpose. An accumulation of several cutlery parts in front of the holding device and the associated risk that cutlery parts hook into each other can in this way be safely prevented by simple means.
    For alignment and separation of the cutlery parts, the feeding device may comprise a thinning device provided with slits corresponding to the width of the cutlery parts so that the unsorted fed cutlery parts can fall down through the slits, for example against a conveyor belt which lies below the thinning device. Other means of transport can of course also be used instead of a conveyor belt. In this respect, this concept should not be construed as limited.
    A problem arises when your cutlery parts are connected to each other in an insoluble manner, ie for example wedged into each other or hooked together and cannot be separated by falling onto the thinning device. These cutlery parts must be sorted away from the cutlery parts which are fed to the holding device in order for the procedure to proceed without disturbances. To this end, in an embodiment of the method according to the invention, it is proposed that the separation device has a surface which slopes towards the horizontal plane along which the cutlery parts which are in engagement with each other without being detachable from each other can be led to a forming container. In this way an optimal separation is obtained of the cutlery parts which are connected to each other and the cutlery parts which are to fall down through the slots on the conveyor belt.
    In addition, in order to improve the separation of the cutlery parts, the separation device can have wedge-shaped elevations between the slits, which enable an optimal sliding of the cutlery parts into the slits. Thereby it is also possible to partially achieve a separation of cutlery parts which are in engagement with each other. For this purpose, the cutlery parts which are in an insoluble engagement with each other will be diverted to a suitable forming container. The wedge-shaped elevations thereby allow an opportunity for a combination of the previously mentioned process steps. This ensures that only aligned and separated cutlery parts are fed to the holding device.
    After the cutlery parts have been picked up on the holding device, the cutlery parts will be aligned under the influence of gravity and according to the invention will be passed on to an identification unit. This identification unit enables the identification of the various cutlery parts and thus generates an output signal which it is made available as an input signal to a sorting device.
    Methods known per se can be used for identifying various cutlery parts. Thus, for example, in accordance with a further development of the method according to the invention, it is possible to distinguish between the cutlery parts by weighing or by optical identification means. The sorting device associated with the identification unit serves to sort the cutlery parts identified by the identification unit into containers arranged for this purpose.
    The process according to the invention achieved, on the whole, a significant improvement in the sorting of various ferromagnetic cutlery parts. The error rate can thereby be reduced to a minimum. Furthermore, through the further alignment and separation of the fed cutlery parts, there is an opportunity to convert the process into extremely short beat times.
    The sorting of various cutlery parts which have been made available without sorting thus takes place in a substantially more scientific manner than in the methods known from the state of the art.
    A device for sorting various ferromagnetic cutlery parts has at least one transport device, a holding device comprising a transport device which can rotate about at least one axis of rotation and which has a surface equipped with several magnets for adhering the cutlery parts, and an identification unit. These minimal components of a device according to the invention enable a very compact and economical manufacture of this device. Through the possibility of a compact construction, valuable space can be saved during, for example, use in commercial kitchens.
    According to a more far-reaching proposal, the device according to the invention can have a holding device which is equipped with at least one rotationally mounted disc, at least one rotationally mounted drum or at least one conveyor belt which is guided around two rotationally mounted shafts. However, the mentioned embodiment variants for a holding device allow the cutlery parts to lie on the surface of the holding device, adhere to it and that they can be aligned independently under the influence of gravity.
    Preferably, a drum is used in the solution according to the invention, since a drum enables a very space-saving construction for the entire device.
    The magnets may be housed in the surface of the rotatably mounted disc or rotatably mounted drum or be attached to this surface. Likewise, an arrangement of the magnets in this way is possible in the embodiment of the holding device in which rotationally mounted shafts are surrounded by a conveyor belt. Here it is within the area of the invention to arrange the magnets on the shafts and / or on the conveyor belt which is guided around the rotationally mounted shafts or on a sliding surface which is found under the conveyor belt.
    A particularly advantageous embodiment of the invention means that the magnets are pivotally mounted about an axis in the holding device. Thereby, an optimal adaptation of the magnetic surface to the cutlery part to be picked up can be guaranteed, since the magnet can be moved and aligned with the cutlery part. The adhesion of the cutlery parts in this solution is decidedly better than in known embodiments. For an improvement of the holding of the magnets and for an optimization of the rotational ability it is further proposed that the magnets be inserted into a magnetic holder. In this way, the storage for the oscillation of the magnets can be arranged in this holder. Although the previously described magnetic device is preferred, it would still be conceivable when the holding device is equipped with a drum or with a conveyor belt guided around two rotationally mounted shafts to arrange the magnets according to an alternative embodiment variant also on the underside of the conveyor belt which is opposite the surface which receives the cutlery parts, which conveyor belt is guided around the shoulders or at least partly around the drum. The continuous increase of the distance between the magnet and the adhering cutlery part can within the scope of the invention then take place, for example, by a transfer to a subsequent conveyor belt which has no magnets.
    Another advantageous embodiment of the invention consists in that the magnets are viewed laterally offset in relation to each other in the transport direction of the cutlery parts. Thereby it can be achieved that each time only one cutlery part is picked up in a safe and reliable manner by the magnet and that the cutlery parts do not mutually obstruct each other.
    In order to ensure that only a single cutlery part is picked up by the magnets each time, a further suggestion is that the magnets have a width corresponding to the cutlery parts to be picked up and consequently are flat.
    In addition, it is a decisive advantage if the magnets have a magnetic field strength which corresponds to the weight of the cutlery parts to be picked up. Due to the latter characteristics of the magnets, separately or in combination with each other, a continuous and reliable mode of operation of the device is achieved.
    Both magnets and electromagnets with adjustable field strength can be used as magnets. A very cost-saving design consists of using permanent magnets. Electromagnets with adjustable field strength give the advantage that the device can be used for cutlery with different weights and sizes without a complete rebuilding or replacement of the holding device.
    In order to achieve an unambiguous separation of the cutlery pieces to be picked up by the holding device and transported, two successive magnets must have a distance relative to each other considered in the direction of rotation of the holding device which is greater than the length of the longest cutlery pieces to be picked up. In accordance with an embodiment of the device according to the invention, the feeding device has at least one conveyor belt and at least one separation device corresponding to this conveyor belt. The separating device can, in the manner previously described, have slots as well as ki-shaped elevations. As a result, a reliable separation of the cutlery parts with respect to a direction and a separation is possible.
    The sorting device controlled by the identification unit may consist of a program-controlled robot or an ejector mechanic or have a program-controlled robot or an ejector mechanic. the invention is explained in more detail below with the aid of the accompanying figures. The exemplary embodiments shown in this respect do not limit the respective variants reproduced, but are only intended for the explanation of the principle of a device according to the invention and for the principle for carrying out the method according to the invention. Here, the same or similar components are denoted by the same respective reference numerals. In order to be able to illustrate the mode of operation according to the invention, only greatly illustrated principle illustrations are shown in the figures, where such components which are not essential to the invention have been dispensed with. However, this does not mean that such components are not present in the invention.
    Figure 1 shows a simplified representation of a device according to the invention for sorting cutlery parts in a lateral view, Figure 2 shows a spatial representation in a top view of a device according to the invention for sorting various ferromagnetic cutlery parts, Figure 3 shows the appearance of a holding device from one side as a single part, Figure 4 shows detail IV from fl figure 3 in an enlarged view and Figure 5 shows the view in the same direction as the arrow V in figure 4.
    The representation and diagrammatically greatly simplified representation in Figure 1 of the device according to the invention for sorting cutlery parts 7 mainly consists of three units. These consist of the feeding device 1, the holding device 2 and the identification unit 3. The feeding device denoted in its entirety by 1 has in the present example a first conveyor belt 20 by means of which the cleaned but not sorted different cutlery parts 7 can be fed. The direction of movement of the first conveyor belt 20 corresponds to the direction of the arrow B in Figure 1. The cutlery parts 7 transported by the first conveyor belt 20 then end up on a subsequent second conveyor belt 10 of the feeding device 1, which has an inclination relative to the horizontal plane. This second conveyor belt 10 is located below a separation device 8 which in the present case has a wedge-shaped elevations 13 which are arranged at a distance from each other. The distances between the wedge-shaped elevations 13 of the separation device 8 form slots 9 with a width which enables the cutlery parts to fall through and down on the conveyor belt 10 which settles under the separation device 8. However, the wedge-shaped elevations 13 and the slots 9 placed between them not only an alignment of the cutlery parts 7. In addition, a separation of the cutlery parts 7 takes place as a result of the standardized geometry of the slits 9.
    The reason for the inclination of the conveyor belt 10 towards the horizontal plane is that the cutlery parts 7 which are connected to each other in an insoluble manner fall against the surface 11, i.e. the highest elevation of the wedge-shaped elevations 13 and can not end up in the separation device 8 due to their connection. slots 9. As a result, the interconnected cutlery parts 7 remain on the surface 11 of the wedge-shaped elevations 13.
    As a result of the inclined slope, they slide along this surface 11 in the direction of the arrow A in fi gur '1 into a collecting container 12 which is set up for this purpose under the conveyor belt 10. In the collecting container 12 the cutlery parts 7 which are connected to each other are collected on a non soluble manner and can thereby be fed for further processing or disposal. Figure 1 shows on the conveyor belt 10, in a sense, fl their arranged, aligned and separated cutlery parts 7. These are moved by the direction of movement corresponding to the arrow C of the conveyor belt 10 in the direction of the holding device 2. The holding device 2 consists in the present case of a drum-shaped conveyor device 5, which is partly surrounded by a conveyor belt 18. The conveyor device 5 is mounted so that it can rotate about an axis of rotation 4, the direction of rotation predicted here being indicated by the arrow D. On the outer periphery of the drum-shaped conveyor device 5 magnets 6 arranged at a distance from each other. The distance 19 between two successive magnets 6 viewed in the circumferential direction is greater than the largest length of the cutlery parts to be picked up. In the transition zone between the conveyor belt 10 and the drum-shaped conveyor device, a contact surface 27 is provided which enables an easy lifting of the cutlery parts in the direction of movement of the conveyor device 5, which rotates about the axis of rotation 4. Thereby the adhesion to the magnets 6 of the cutlery parts 7
    In addition, the contact surface 27 serves for the bridging of a gap which exists between the conveyor belt 10 and the conveyor device 5.
    As can be seen from Figure 1, the conveyor belt 18 does not completely run around the drum-shaped conveyor device 5. Consequently, only a part of the underside 17 of the conveyor belt 18 abuts directly against the surface of the drum-shaped conveyor device 5. A further part of the conveyor belt 18 similarly forms a component of the supply to the identification unit 3 and thus has a flat section.
    As a result, the cutlery parts 7 can on the one hand adhere to the transport device 5 by the magnetic field strength of the magnets 6. On the other hand, the cutlery parts 7 are held by the static friction between the surface 16 of the conveyor belt 18 and the cutlery part 7.
    The sorting of the cutlery parts 7 according to the invention proceeds as follows: first the cleaned, unsorted, different cutlery parts 7 are fed by the conveyor belt 20. After the transfer from the conveyor belt 20 to the separation device 8 a separation takes place and in any case a alignment and separation of the cutlery parts 7 through the wedge-shaped elevations 13 so that the cutlery parts 7 fall into the slots 9 of the separation device 8 and from these fall down on the conveyor belt 10 which is located below them.
    The conveyor belt 10 transports the cutlery parts in the direction of the holding device 2.
    By the rotation of the transport device 5 about the axis of rotation 4, exactly one cutlery part 7 can be picked up through each magnet 6. This cutlery part 7 adheres with one of its ends to the magnet 6 and is passed through the rotational movement of the transport device 5 with about axis of rotation 4. During this movement, the cutlery part 7 aligns in the vertical direction due to the action of gravity. In the upper part, ie within the transition zone between the conveyor device 5 and the identification unit 3, the conveyor belt 18 is flat. Here, in accordance with the invention, an increase of the distance between the magnets 6 and the cutlery part 7 is achieved. This increase of the distance results in the conveyor device continuing its rotational movement while the conveyor belt 18 transitions into a flat area. The distance between the magnet 6 and the cutlery part 7 is then increased until the magnetic force is no longer sufficient to hold the cutlery part 7. It remains in an aligned position in the last occupied position on the flat part of the conveyor belt 18. and can thus be fed to the subsequent identification unit 3.
    The guide plate 15 shown in Figure 1 within the area of the pouring device 2 is intended for stabilizing the alignment of the cutlery parts 7. For carrying out the method according to the invention, these guide plates 15 are not necessary. However, in some circumstances they represent a meaningful complement. Figure 2 shows in a perspective view an entire plant for sorting various ferromagnetic cutlery parts. Also in this case a conveyor belt 20 is arranged to receive cleaned, unsorted, various cutlery parts in bulk and lead them on to a subsequent separation device 8. This separation device 8 consists of wedge-shaped ridges 13 between which slits have been formed, and under these slits 9 there is a further conveyor belt 10 of the feeding device 1. When the cutlery parts 7 have been separated, separated and aligned inside the separating device 8, they are fed by the movement of the conveyor belt 10 in the direction of the conveyor device holding device 2. The conveyor 5 can rotate about the axis of rotation 4 After the cutlery parts 7 are adhered to the magnets 6, the cutlery parts 7 align independently due to gravity. With a supporting effect, however, a respective guide plate 15 is present here, which represents a limitation of the transport device 5 at the outside. The cutlery parts 7 are further transported in this separated and aligned position from the conveyor device 5 and by the increased distance between the magnet 6 and the cutlery part 7 adhering thereto they are separated from the magnets due to the transition of the conveyor belt 18 from the drum-shaped conveyor device 5 to a flat section. The cutlery parts 7 in this case remain in an aligned position and are moved under an identification unit 3 along the same. As the identification unit 3, in the exemplary embodiment shown in Fig. 2, an optical reader device is used which can distinguish the cutlery parts 7 from each other due to their shape characteristics. As a result of the optical detection of the individual cutlery parts 7, this identification unit 3 generates an output signal which is made available as an input signal to the subsequent sorting device 14. After leaving the identification unit 3, the cutlery parts 7 are moved further on the conveyor belt 23 in the same direction as arrow E in Figure 1 until they are within an area within which containers 25 and 26 of the sorting device 14 are located for the cutlery parts 7 in question 7. The output signal originating from the identification unit 3 and which forms an input signal for the sorting device 14 now allows association with said containers 25 and 26, respectively.
    The entire system shown in Figure 2 further has a control panel 22 through which the settings essential to the device can be performed by the control means 21 shown.
    Figure 3 shows a side view of a holding device 2 as a separate part. In the case of the holding device 2, it is a drum-shaped transport device 5 and - as already explained in connection with fi gur 1 - which is partly surrounded by a conveyor belt which is not reproduced in fi gur 3. The transport device 5 is mounted so that it can rotate about an axis of rotation 4. On the outer periphery of the drum-shaped transport device 5, the magnets 6 are arranged. The magnets 6 have a displacement in the transverse direction relative to the direction of rotation of the rotating device, ie they are not arranged on a common peripheral line of the transport device 5, but with a respective displacement relative thereto. This enables an optimization of the picking of the cutlery.
    As can be seen from the enlarged detail illustration in Figure 4, the magnets 6 are arranged in the holding device 2 and here in the trumpeted transport device 5 so that they can pivot about an axis 28 in order in this way to be able to be oriented in the direction of the cutlery part to be picked up. . To improve the mountability and storage of the magnets 6, these are inserted in a respective magnet holder 29.
    Furthermore, Figure 5 shows a view of the magnet 6 in the same direction as the arrow V in Figure 4.
    This again shows the mounting and pivotability of the magnet 6 which is accommodated in the magnet holder 29. The shaft 28 is designed as a shaft pin 30, the magnet holder 29 being held on both sides of a respective shaft pin and is thus mounted together with the magnet 6 so that it can pivot about the axis 28.
