    [0001] The present invention relates to methods and systems for selectively conducting and discharging food products. In addition, the present invention relates to methods and systems for weighing and ordering food products.
    [0002] Within industries such as the foodstuff industry, weighing and sorting machines have been described in publications such as documents No. US 6,234,297, US 6,015,049, WO 98/49892, US 6,321,914, US 5,526 .437, US 4,569,434, EP 0 593 126 and EP 0 900 601, all such United States patents are incorporated into this specification by reference.
    [0003] In the foodstuff industry there is a need to order products or articles at high speeds and yields according to various physical characteristics such as size, color or weight, alternatively by any combination of these. Industrially packaged food products, such as pieces or poultry, are usually packaged in packages of approximately equal weight, regardless of the quantity of pieces included in the package. As such, many food product packages include more than one individual product, that is, the packages usually include at least two products. Some product packages, such as chicken breast packages, typically include three pieces in each package, however, the amount can be larger such as four or five pieces within the same package, as long as all packages are approximately the same weight .
    [0004] In order to ensure that food products of varying weight can be combined in packages that are approximately the same weight, a weigher with multiple heads can be used. In a weigher with multiple heads, which is known in the prior art, the individual pieces of food products are randomly distributed among a large number, such as 5 to 50, preferably 8 to 20, of weighing systems. The weighing system typically takes the form of receptacles. A computer is then used to calculate the most favorable combination of receptacles to achieve a target weight and the chosen receptacles are subsequently emptied so that the food products contained in the receptacle leave the receptacle and end up in a common package. There is, therefore, a need to keep the weight of the products contained within each container as low as possible so that a large number of combinations are possible. For an ideal combination number, it is an attribute of the present invention that no more than one food product at a time is received within each receptacle.
    [0005] In Applicant's International Application No. WO 2006/092148, a weighing arrangement is shown that has a metering mechanism for controlled conduction of portions of product material from a feed to a weighing system. The metering mechanism comprises a motor driven transport propeller formed as a helical shaped rod positioned in an open trough to carry the product material.
    [0006] Such dosing mechanisms, as described above, provide a very smooth and accurate delivery of products to the weighing system. However, in some situations, the applicant has experienced that more than one product at a time can be delivered to the weighing system. The delivery of more than one product at a time to each receptacle can occur particularly when a plurality of products are located in an overlapping relationship. In the event that more than one product is located within a single receptacle, it will be more difficult to combine the contents of the receptacle with the other pieces received within other receptacles. In the worst case, no combination will be possible within the target weight and the contents of the receptacle must be discarded, which constitutes a loss of products, or circulated again, that is, redirected to food, which constitutes a waste of time and wear and tear. additional product. Additional recirculation may eventually render the product unusable.
    [0007] Thus, it is the aim of the present invention to provide techniques for delivering food products one at a time to a receptacle.
    [0008] It is a particular advantage that the techniques according to the present invention can be implanted in existing weighing arrangements, such as the arrangement described above, without any real modification of the arrangement itself.
    [0009] The above need, the above objective, the above attribute and the above advantage together with numerous other objects, advantages and attributes that will be evident from the detailed description below of the preferred and present modalities are obtained according to the teachings of a first aspect of the present invention by a method for selectively conducting and discharging several food products one at a time, the method comprises; i) providing a feeding system, the feeding system comprises: a) an inlet end for receiving food products, the food products being substantially solid, b) an outlet end for selectively discharging food products one at a time, c ) a receptacle located below the outlet end for receiving the individual food product when discharged from the outlet end, d) a determination unit located at the outlet end and e) a feeder for guiding food products from the inlet end to the outlet end, ii) introducing bulk food products to the first end of the feed system individually or in an at least partially overlapping relationship, iii) determining a first operational mode when no food product is present at the outlet end and no food product is present in the receptacle, iv) drive in the p first operational mode through the feeder the food products in a direction from the input end to the output end at a first average speed, v) determine a second operational mode when a first individual food product is present at the output end and in the food product is present in the receptacle, vi) in the second operating mode, through the feeder, feed the food products in a direction from the input end to the output end at a second average speed, the average speed being less than the first medium speed, vii) determining a third operating mode when the first individual food product leaves the outlet end or is received into the receptacle, viii) stopping the feeder in the third operating mode until the first individual food product has left the receptacle.
    [00010] Food products can occasionally be introduced at the entrance to the food system one by one, that is, with a distance or spacing between each food product. However, such distances between food products are a waste of time and should therefore be avoided in principle. However, since food products are supplied in bulk and the receipt of food products at the inlet end is at least somewhat random, it can often occur that a spacing is present between one or more food products. More commonly, however, as food products are supplied in bulk, food products enter an overlapping relationship, for example, the back of a first food product can be overlapped or it can overlap the front of a product subsequent food.
    [00011] Food products can in principle be any food product, however, preferably food products consist of sticky food products such as pieces of poultry or similar. The size of the food product can be in the range above a minimum size product which, at least for industrial purposes, can still be handled individually, such as the size of a chicken wing. The typical size of food products can be considered to be substantially the size of a chicken breast.
    [00012] The feeder that is powered by a motor, which in turn is controlled by a control unit, transports food products from the input end to an output end located opposite the input end. The outlet end is monitored by a determination unit, which is also in communication with the control unit and detects the presence or absence of a food product.
    [00013] The first operating mode is used when no food product is present at the outlet end. The average speed used in the feeding mechanism is high, as the time loss between two individual food products must be as low as possible.
    [00014] When the determination unit detects a food product at the outlet end, the second operating mode is used. In the second operating mode, the average feeder speed is lower, so that the first food product approaches the receptacle slowly. At some point, the first food product begins to slide downwards towards the receptacle by gravity only without or with only limited participation from the feeder. This typically happens when the food product's center of gravity is beyond the outlet end. Since the feeder is running at a low speed, a second possible food product located near the outlet end will remain in the feed system and will not be pushed into the receptacle.
    [00015] When the determination unit detects that the individual food product has left the outlet end, the third operating mode is used. In the third operating mode, the feeder is temporarily stopped in order to prevent any second individual food product from entering the receptacle before the receptacle is emptied. After the receptacle is emptied, either the first operating mode can be used in the event that no food product is present at the outlet end or the second operating mode can be used in the case where a second food product is present at the outlet end.
    [00016] According to an additional modality of the first aspect, in step viii), before the stop and as long as no second individual food product is present at said outlet end, conduction in the third operational mode is carried out through the feeder of the food products in one direction from the input end to the output end at a first medium speed until a second individual food product is present at the output end, and only then is it stopped.
    [00017] In the event that the first individual food product has left the outlet end and there is no second individual food product located at the outlet end, the feeder can, in order to save time, continue to run until the second food product individual is present at the outlet end, at which point the feeder must be stopped and wait for the receptacle to empty. In the event that the receptacle has already been emptied, the feeder can continue in operating mode two immediately, without stopping. However, this situation typically hardly ever occurs, as it indicates that the system is not working optimally. In an effective system, a new piece of food product must be received in the receptacle as soon as possible after it has been emptied.
    [00018] According to an additional embodiment of the first aspect, the determination unit comprises a flap mounted on the outlet end, the flap assuming a first position adjacent to the outlet end when no food product is present at the outlet end causing the determination unit determines the first operating mode, the flap being pushed away from the outlet end when a front portion of an individual food product is present at the outlet end causing the determination unit to determine the second operating mode.
    [00019] In order to achieve a simple and effective monitoring of the outlet end of the feeder system, a flap can be used. The flap may comprise a plate or similar structure which is hinged at the top of the outlet end so that it rests initially with a lower end at the outlet end. When a first individual food product proceeds to the outlet end and projects beyond the outlet end with its front part, it will pivot the flap outward and push the bottom end of the plate away from the outlet end. This will cause the determination unit to indicate that the second operating mode should be used. The first individual food product will continue towards the receptacle at a slower pace.
    [00020] According to an additional embodiment of the first aspect, the determination unit comprises a flap mounted on the outlet end, the flap assuming a first position adjacent to the outlet end when no food product is present at the outlet end causing the determination unit determines the first operating mode, the flap being pushed away from the outlet end when a front portion of an individual food product is present at the outlet end causing the determination unit to determine the second operating mode, the flap returning to the outlet end when a rear portion of an individual food product is present at the outlet end causing the determination unit to determine the third operational mode.
    [00021] When the first individual food product has left or is close to leaving the outlet end, the flap will pivot back to the outlet end. This indicates that the third operating mode must be used, that is, the feeder must be stopped in order to prevent a second individual food product from leaving the outlet end. The receipt of the first individual food product in the receptacle, for example, can be confirmed by the increase in the weight of the receptacle. As the receptacle typically constitutes a weighing compartment, this detection does not require any real modification to the system as such. In the rare case that no receipt of the food product is confirmed within a short period of time, the return of the tab may be caused by a food product with a strange shape and the second operating mode may be returned.
    [00022] In the event that the lower end of the flap returns only partially to the outlet end, this may indicate that a second food product is located at the outlet end. In this case, the feeder is stopped and after the receptacle has been emptied, the system continues in the second operating mode. Conversely, in the event that the lower end of the flap completely returns to the position adjacent to the outlet end, no food product is present at the outlet end and after the receptacle has been emptied, the system continues in the first operating mode.
    [00023] According to an additional embodiment of the first aspect, the determination unit comprises one of an optical determination unit, a radar determination unit, a mechanical determination unit or a laser determination unit. Other units of determination can be contemplated, such as units of determination that do not require contact with the food product, for example, optical such as photocell, laser, radar. Alternatively, other mechanical determination units, other than the tab previously described, can be used such as buttons or the like.
    [00024] According to an additional embodiment of the first aspect, the second average speed includes stopping the feeder for a specific period of time, preferably the feeder is stopped for a period of time between 0.1 seconds and 10 seconds. In the present context, it refers to an average speed that must be measured over a relatively long period of time. The first and second average speeds can be achieved by an engine that varies its speed over time. In some embodiments, an engine that has a constant high speed can be used and the average turret speed is achieved by stopping and starting the engine. This can simplify the engine control unit.
    [00025] According to an additional embodiment of the first aspect, the feeder of the feeding system comprises a conductive mat, a conductive cylinder and a vibrating conductor. The type of conductor used may vary depending on the type of food product to be driven.
    [00026] According to an additional embodiment of the first aspect, the feeder comprises a helical conductor. Preferably, in the present context a helical conductor is used. The benefits of the helical conductor are mentioned above as well as in the prior art document cited No. WO 2006/092148.
    [00027] According to an additional embodiment of the first aspect, the helical conductor is interchangeable by means of a pressure mechanism. An easily interchangeable helical conductor allows easy cleaning of the system and a quick adaptation of the system to a different food product, for example, a large propeller for chicken breasts and a small propeller for chicken wings.
    [00028] According to an additional modality of the first aspect, the helical conductor has an increasing pitch along its length. An increasing step along the driving path between the inlet and the outlet allows for smooth transport of product material.
    [00029] According to an additional modality of the first aspect, the helical conductor consists of a helical rod. A helical rod allows food products to be guided smoothly and in a well-defined path.
    [00030] According to an additional embodiment of the first aspect, the helical rod includes a core or alternatively the helical rod has no core. The provision of a core can prevent the product material from falling between the turns of the helical rod. However, a helical conductor without a core can prevent food products from being compressed between the core and the helical rod. In some embodiments, the core can rotate synchronously with the helical rod or, alternatively, be stationary.
    [00031] The above need, the above objective, the above attribute and the above advantage together with numerous other objects, advantages and attributes that will be evident from the detailed description below of the preferred and present modalities are obtained according to the teachings of a first aspect of the present invention by a feeding system for selectively conducting and discharging several food products one at a time, the feeding system comprising; a) an inlet end to receive the food products, the food products being substantially solid, the food products being introduced in bulk at the first end of the feeding system individually or in an at least partially overlapping relationship, b) an outlet end for selectively discharge the food products one at a time, c) a receptacle located below the outlet end to receive the individual food product when discharged from the outlet end, d) a determination unit located at the outlet end, the determination unit determining a first operating mode when no food product is present at the outlet end and no food product is present at the receptacle, a second operating mode when a first individual food product is present at the outlet end and no food product is present at the receptacle and a third operational mode when the first individual food product leaves the outlet end or is received into the receptacle ee) a feeder to guide food products from the inlet end to the outlet end, the feeder conducts: i) in the first operational mode through the feeder the food products in one direction from the input end to the output end at a first medium speed, ii) in the second operating mode through the feeder the food products in one direction from the input end to the outlet end at a second average speed, the second average speed being less than the first average speed, iii) in the third operating mode stop the feeder until the first individual food product has left the receptacle.
    [00032] The above system according to the second aspect is preferably used together with the above method according to the first aspect.
    [00033] The above need, the above object, the above attribute and the above advantage together with numerous objectives, advantages and attributes that will be evident from the detailed description below of the preferred and present modalities are obtained according to the teachings of a third party aspect of the present invention by a multi-head weighing system comprising a plurality of feeding systems according to the second aspect and a receiving section for receiving a plurality of bulk food products, the receiving section communicating with each end inlet of each switchgear, each of the receptacles of each switchgear constituting a weighing compartment.
    [00034] The receiving section preferably has a conical shape so that food products released from above can slide towards the inlet ends of the dispensing devices. The weighing system with multiple heads is preferably controlled by a control unit, which monitors the weight of the food products received in the receptacle and the result of determining the current operating mode. The control unit controls, based on the information above, the emptying of the receptacle and the speed of the helical conductor.
    [00035] According to an additional modality of the third aspect, the receiving section is centrally located and the plurality of distribution devices are distributed around the centrally located receiving section.
    [00036] In order to save space and achieve a uniform distribution of food products, the circular configuration above the weighing assembly with multiple heads is preferred. Brief Description of Drawings
    [00037] Fig. 1 is a weigher with multiple heads that includes a feeding system, Fig. 2 is a series showing a plurality of food products that are driven by the feeding system, Fig. 3 is a feeding system feeding that includes a control unit, Fig. 4 is a series showing feeding systems that have alternative determination units and Fig. 5 is a series showing feeding systems that have alternative feeders. Detailed Description of Drawings
    [00038] Fig. 1 shows a weighing arrangement with multiple heads 10 including a receiving section 12 and a feeding system 14. The receiving section 12 has a conical shape for receiving food products that are delivered from above the weighing section. receiving 12. Food products (not shown here) can be sticky food products such as pieces of poultry. Food products are typically distributed at random in the receiving section 12 and are due to the conical shape of the receiving section 12 which moves towards the periphery of the receiving section 12. The receiving section 12 may optionally be rotating in order to distribute the food products more evenly along the periphery of the receiving section 12 and to prevent any food products from remaining in the receiving section 12 for a longer time. On the periphery of the receiving section 12, the plurality of systems power supply, all given in reference numeral 14, is located. Each supply system 14 comprises a supply channel 16, in which a helical conductor 18 is located. The helical conductor typically constitutes a hollow helically shaped rod. The distance between two turns typically corresponds to the size of the food product to be driven, for example, about 0.1 m in the case of a chicken breast. The feed channel 16 extends from an input end 20 located adjacent to the receiving section 12 and an output end 22 located opposite to the input end 20. Below the output end 22, a weighing compartment that constitutes a receptacle 24 is located. The outlet end 22 of the feed channel 16 is covered by a pivotable flap 26, which will be discussed in more detail below. Food products entering the receiving section 12 will be randomly distributed among the feeding systems 14. Thus, an individual food product will enter the inlet end 20 of a feeding system 14 and be transported along the feeding channel 16 by the driver helical 18 towards outlet end 22. Flap 26, which forms part of a determination unit, as will be described in detail in connection with Fig. 2, detects the presence of the food product and allows an individual food product enter receptacle 24. Receptacle 24 is subsequently emptied onto a hollow shaft 28, which leads towards a delivery chute 30. In practice, the content of two or more receptacles 24, the content in total having a weight approximately corresponding to the predetermined target weight, it is emptied into chute 30. Food products thus received in delivery chute 30 are delivered to a packaging station ( not shown here), where the combined food products are packaged in a single package.
    [00039] Fig. 2A shows a sectional view of a supply system 14 that operates in a first operational mode. The feed channel 16 of the feed system 14 includes a first food product 32 and a second food product 32 'which partially overlaps the first food product 32, with both food products 32, 32' being directed towards the flap 26 by medium of helical conductor 18. A third food product 32 is located on the periphery of the receiving section 12 at the inlet end of the supply system 14. Helical conductor 18 is driven by an electric motor 34. In the present first operating mode, no product food has reached the outlet end of the supply system 14. The flap 26, which is hinged by a hinge 36 located above the outlet end 22, thus does not detect any food products. Thus, in the first operating mode, the motor 34 drives the helical conductor 18 at a high speed. The high speed can be achieved by operating the helical conductor at a rotational speed of, for example, 0.5 to 5 revolutions per second. The receptacle 24 is supported by a receptacle support 38, which also measures the weight of the contents of the receptacle 24. The lower end of the receptacle 24 is closed by a door 40. The door 40 is held in a closed position by a locking mechanism 42.
    [00040] Fig. 2B shows a supply system 14 that operates in a second operating mode. The feed system enters the second operating mode when the determination unit comprising flap 26 and hinge 36 detects the presence of the first food product 32 at the outlet end 22 of the feed system 14. The presence of the first food product 32 in the outlet end 22 is detected by pivoting out of flap 26 around hinge 36. In the second operating mode, motor 34 drives helical conductor 18 at a low speed. The low speed can be achieved by operating the helical conductor at a speed of, for example, 0.1 to 0.5 revolution per second. Alternatively, the helical conductor is operating interchangeably at a higher speed and stopped for about 0.5 seconds.
    [00041] Fig. 2C shows the supply system 14 operating in the second operating mode. In the second operating mode, the first food product is pressed slowly past the outlet end 22 and pushes the flap 26 further away from the outlet end 22. When the first food product 32 is close to leaving the outlet end 22, the flap 26 it will begin to move or pivot back towards exit end 22. At that time, the feed system 14 enters a third operating mode, which will be described in more detail below.
    [00042] Fig. 2D shows a supply system 14 in a third operating mode. In the present situation, the first food product 32 left the outlet end 22 of the supply system 14, the flap 26 moved back to the outlet end 22 and the motor 34 that drives the helical conductor 18 was stopped in order to prevent that the second food product 32 'leaves the outlet end 22 of the feeding system 14. The first food product 32 is received at the bottom of the receptacle 24.
    [00043] Fig. 2E shows the supply system 14 when it returns from the third operating mode to the second operating mode. When the weighing is completed and the door 40 opens by unlocking the locking mechanism 42, the first food product 32 leaves the receptacle 24. In the present situation, a second food product 32 'is located at the outlet end 22 and thus the second mode operation is resumed, in the second operating mode as determined above the motor 34 drives the helical conductor 18 at a low speed as indicated by the arrow. Door 40 is closed as soon as possible after emptying the first food product 32 in order to be ready to receive the second food product 32 '
    [00044] Fig. 2F shows a supply system 14 when it is in a third alternative operating mode. In the present third alternative operating mode, the second food product 32 'remains in the receptacle 24 while no food product is present at the outlet end 22 of the feed system 14. In the present situation, the helical conductor 18 is not stopped and instead the electric motor 34 drives the helical conductor 18 at a high speed similar to the first operating mode. However, in the event that the third food product 32 "located in the feed channel 16 enters the outlet end 22 of the feed system 14 and thus pushes flap 26 outward, the helical conductor is stopped in order to prevent the third food product 32 "enter receptacle 24 before the second food product 32 'has left receptacle 24.
    [00045] Fig. 3 shows the supply system 14 which includes a control unit 44. The control unit 44 is connected to the hinge 36 of the flap 26, the motor 34 of the helical conductor 18, the support 38 of the receptacle 24 and the locking mechanism 42 of the door 40. In this way, the control unit 44 can detect the angle and angular speed of the joint 36 and the weight of the contents of the receptacle 24. This information can be used to control the speed of the motor 34 and the unlocking lock of the locking mechanism 42.
    [00046] Fig. 4A shows an alternative embodiment of a 40 'feeding system. In the alternative mode 40 ', the flap 26 and the hinge 36 are replaced by photocells 46. The presence of a food product at the outlet end 32 is detected by the photocells 46 and, as a consequence, the second operating mode can be started.
    [00047] Fig. 4B shows an additional alternative mode of the 14 "power system, in which the photocells have been replaced by a different electromagnetic determination unit such as a radar or laser 48.
    [00048] Fig. 5A shows an additional modality of the 14 '"feeding system, in which the helical conductor has been replaced by a conductive track 50. A conductive track can be preferred in the case where the food products to be driven are very fragile.
    [00049] Fig. 5B shows an additional modality of a 14IV feeding system, in which the conductive belt has been replaced by a vibrant conductor. Vibrant conductors, on the other hand, can be used in the event that food products are very robust.
    [00050] Fig. 5C shows an alternative mode of a 14V supply system, in which the helical conductor 18 'is connected to the motor 34 by means of a pressure mechanism 54. The connection between the motor shaft and the helical conductor typically comprises connecting a female part attached to the end of the motor shaft to a male part attached to the end of the helical conductor, or vice versa. The pressure mechanism can, for example, be provided by means of a generally known bayonet coupling between the motor and the helical conductor. Other possibilities include a spring and a protruding sphere located at the end of the helical conductor and a corresponding recess in the motor shaft. The connection between the helical conductor and the shaft is achieved by pressing and interlocking the ball with the corresponding recess provided on the motor shaft.
    [00051] Fig. 5D shows an additional modality of a 14VI feeding system, the 18 "helical conductor is equipped with a core 56. A core will prevent any food product from falling to the bottom of channel 16. A product that falls between two turns of the helical conductor 18 can sometimes get caught between the bottom of the channel 16 and the helical conductor. With the core 56 supplied, all food products are transported above the core in the upwardly oriented portion of the helical conductor 18 "and thus food products will not get stuck.
    [00052] Fig. 5E shows an additional modality of a 14V "supply system, the helical conductor 18" 'has an increasing pitch along its length from the input end 20 to the output end 22. Increasing it if the pitch of the helical conductor slightly, that is, by increasing the distance between two turns of the propeller along the distance between the inlet and the outlet, ensure that no food product is compressed between two turns of the propeller.
    [00053] The present invention should not be considered limited by the examples described above, for example, increasing the radius of the system and maintaining the dimensions of the receptacles results in the possibility of increasing the number of receptacles, thereby increasing the performance of the system. In addition, although the above examples refer to food products only, the above techniques are also applicable to similar non-food products. List of parts with reference to the figures 10.
