Description

Technical Field

[0001] The present application relates to the field of automated food packaging equipment, and in particular to automated food packaging equipment comprising a food sorting device. Background Art

[0002] Nowadays, the packaging lines in food processing plants are basically automated, including food picking, packaging, and boxing, replacing manual labor and improving food packaging efficiency. Some snack foods such as biscuits and potato chips contain multiple types of food in one package for aesthetic reasons.

[0003] Take biscuits as an example. A bag of biscuits contains multiple biscuits of different styles, colors and appearances. The biscuits of different styles are arranged in a certain order to give consumers visual appeal and increase sales. Briefly describe the biscuit packaging process. Biscuits are uniformly transported from the production line to the packaging line, arranged in a predetermined order, and divided into batches by bag. The number of biscuits in a batch corresponds to the number of biscuits in a packaging bag. Each batch is transported at intervals. At the same time, the packaging bag is bent to wrap a single batch of biscuits. The middle part of the side of the packaging bag is sealed vertically and the two ends are sealed horizontally to complete a single package.

[0004] In the traditional solution, in order to achieve biscuit sorting, biscuits of different styles are usually equipped with different conveyor lines, and the conveying speed of the conveyor line is controlled so that multiple biscuits can be input into the packaging line in order. Under this solution, the error rate of biscuit sorting is high. The biscuits are eliminated by manual control equipment and manually sorted and then put back into the packaging line. Due to the low efficiency of manual sorting, the biscuits cannot be sent back to the packaging line in time, and therefore, empty packages often occur. Summary of the invention

[0005] In order to further improve the degree of automation of a food packaging line and enhance the efficiency of food sorting, the present application provides an automated food packaging device including a food sorting device.

[0006] The present application provides a food automatic packaging device including a food sorting device, which adopts the following technical solution: An automatic food packaging device including a food sorting device comprises a conveying channel for conveying food, wherein a clamp is slidably connected in the conveying channel, and the clamp is used to clamp the food, and is characterized in that it also comprises: A rotating rod is vertically arranged and rotatably connected to both sides of the conveying channel, a plurality of spacer claws are slidably connected between the rod bodies of the rotating rods, one end of the spacer claws extends above the conveying channel, and an identification component is arranged on the rotating rod; A sorting device, arranged at one side of the conveying passage, for re-sorting the food; A gripper assembly is disposed between the conveying channel and the sorting device to convey the food between the conveying channel and the sorting device; An access rail, connecting the sorting device and the conveying channel, and used for sliding guidance of the gripper assembly; The outgoing rail is used for sliding guidance of the gripper assembly, and its sliding direction is opposite to the sliding direction of the incoming rail.

[0007] By adopting the above technical solution, the conveying channel is the main conveying structure of the packaging line. The above rotating rod, sorting device, gripper assembly, incoming rail and outgoing rail are all arranged on both sides of the conveying channel to directly detect the arrangement order of the food conveyed on the conveying channel. If disordered food is detected, it is directly conveyed to the sorting device by the gripper assembly for sorting. After sorting, it is conveyed back to the original position of the food on the conveying channel by the outgoing rail to fill the gap; it will neither affect the subsequent food transportation nor cause the problem of empty packaging; In the above process, the rotating rod rotates synchronously with the conveying of the conveying channel, and the rotation angular velocity of the rotating rod should be adapted to the conveying speed of the conveyor belt, so that the structure of the partition claws on the rotating rod does not interfere with the food being conveyed during rotation, that is, when each partition claw rotates to the top of the conveying channel, it should just rotate to the part between two adjacent batches of food. Therefore, when the rotating rod rotates, the above identification component is set between two adjacent partition claws. When the rotating rod rotates, the identification component can keep facing the food, which increases the identification time and improves the identification accuracy. The identification of the identification component is the data source for the subsequent sorting device. As the rotating rod rotates and the conveying channel conveys, the identification component identifies the order of food arrangement in each batch of food according to a pre-written program. When an error in the order of food arrangement is detected within an identification cycle, the gripper component enters a ready-to-operate state. When a batch of incorrectly identified foods is conveyed to one side of the gripper component, the gripper component grabs them from the conveying channel and conveys them to the sorting device, which sorts them according to the order pre-written by relevant personnel. An identification unit should also be set in the gripper component to re-detect the food transported into the sorting device to determine the order of arrangement.

[0008] Optionally, a horizontally arranged flip plate is arranged above the conveying channel, and the rotating rod is arranged on the bottom side of the flip plate; The flip plate is provided with a flip assembly for flipping the flip plate from a horizontal state to a vertical state.

[0009] By adopting the above technical solution, the flip plate is used to support the above rotating rod, the gripper assembly, the access rail and the exit rail, and the four are integrated into a module structure. When the flip plate is reversed by the flip assembly, the rotating rod is flipped at the same time, and the bottom surface of the flip plate in a horizontal state is changed to a vertical state facing the relevant personnel, so that the relevant personnel can check and clean up the food residues in a unified manner. Due to the high standards of hygiene and safety in the food industry, food packaging equipment is prone to leave food residues and debris on the surface of the device and equipment when conveying and clamping food, which are prone to spoilage over time. The spoiled food debris adheres to the subsequently conveyed food residues and reduces food safety. Therefore, relevant personnel are required to regularly clean the food residues on the equipment. After the above-mentioned flip plate is flipped to a vertical state, in addition to facilitating relevant personnel to clean the rotating rod, gripper assembly, connecting rail and connecting rail, the conveying channel can also be opened from one side, making it convenient for relevant personnel to scrub the inside of the conveying channel.

[0010] Optionally, the top end of the rotating rod extends through and to above the flip plate, a magnetic wheel is provided at the top end of the rotating rod, and a driving member is provided above the flip plate corresponding to the magnetic wheel at the top end of the rotating rod.

[0011] By adopting the above technical solution, a magnetic wheel is selected as the driving member of the rotating rod, and the magnetic wheel is a non-contact driving component with high transmission efficiency; In addition to the non-contact type that avoids friction energy consumption, the non-contact transmission structure of the magnetic wheel does not require relevant personnel to disassemble when the flip assembly is reversed. If the traditional mechanical connection transmission method is adopted, relevant personnel need to disassemble the mechanical structure in advance when turning the flip plate, which is more troublesome.

[0012] Optionally, the gripper assembly comprises: The electric clamp is vertically arranged, and the top end is slidably connected to the access rail and the exit rail, and slides along the access rail to above the sorting device, and slides along the exit rail to above the conveying channel.

[0013] By adopting the above technical solution, the electric clamp is vertically arranged and vertically slidable, and is arranged on the access rail and the exit rail, and horizontally slides along the access rail and the exit rail, and slides to the top of the corresponding position and then moves downward to clamp the corresponding food; Therefore, when the recognition component recognizes that the order of food is disordered, after the food slides to the access rail, the electric clamp slides along the access rail to the top of the conveying channel, moves down, and clamps the batch of neatly arranged but misordered food. The electric clamp clamps the food and moves up, slides along the access rail to the top of the sorting device and then moves down. The clamping jaws of the electric clamp release, clamp the food, and place the misordered food in the sorting device. After the food is sorted, the food is transported to the access rail and transported back to the packaging line according to the reverse process of the above process.

[0014] Optionally, the sorting device includes: A conveying rail, connecting the incoming rail and the outgoing rail, the conveying rail is parallel to the conveying channel, and the conveying rail is composed of an upper conveying rail and a lower conveying rail arranged in parallel; There are a plurality of sorting slots which are evenly spaced along the length direction of the conveying rail, each of which is arranged corresponding to a single food, and a plurality of the sorting slots are slidably connected to the conveying rail to convey the food.

[0015] By adopting the above technical solution, the sorting slot and the conveying rail are the main structures for re-sorting the same batch of food. The number of sorting slots corresponds to the number of food in the same batch, so that one food corresponds to one sorting slot, that is, when the above electric gripper conveys a batch of food to the sorting slot, one sorting slot is used to install one food; Each guide rail of the upper conveyor rail and the lower conveyor rail is vertically arranged in a vertical plane, so as to facilitate the track conversion of the sorting slot. The upper conveyor rail is the original guide rail of the sorting slot, that is, the sorting slot should be installed on the upper conveyor rail under normal conditions to prepare for conveying misordered food. The lower conveyor rail is the main conveyor rail of the sorting slot. In order to avoid structural interference, the height difference between the upper conveyor rail and the lower conveyor rail should be greater than the height of the sorting slot, that is, when the sorting slot is installed on the upper conveyor rail, its bottom end should not intersect with the surface where the lower conveyor rail is located, but should be above the lower conveyor rail. The sorting slots are re-sorted according to the recognition results of the above-mentioned recognition components. The multiple sorting slots on the upper conveyor rail are transported to the lower conveyor rail in the correct order, and then slide along the lower conveyor rail to the connecting rail in turn to complete the correct sorting of the sorting slots, and then complete the sorting of the food. The sorted food is transported back to the conveying channel by the electric gripper.

[0016] Optionally, the sorting device further includes: A sliding assembly is arranged at the top side edge of the slot wall of each of the sorting slots, and is used for the sorting slot to slide along the conveying rail and for the sorting slot to switch between the upper conveying rail and the lower conveying rail. By adopting the above technical solution, the sliding assembly is used for the reciprocating switching of the sorting slot between the upper conveyor rail and the lower conveyor rail. The upper conveyor rail is the starting rail, and the lower conveyor rail is the main conveyor rail in the sorting process. The switching between the upper conveyor rail and the lower conveyor rail requires the sliding assembly to be realized. In order to reduce the structural cost, it can be realized in the form of an angle cylinder and a slider; The rotation direction of the corner cylinder is perpendicular to the length direction of the upper conveyor rail. When the corner cylinder is not operating, the slider slides along the upper and lower conveyor rails, and the rotating cylinder drives the slider to rotate, so that the parts where the two sliders are located rotate to a vertical state. Under the action of gravity, the sorting trough separates from the upper conveyor rail. During the falling process, the corner cylinder rotates in the opposite direction to restore the slider to a horizontal state, so that the slider is placed on the lower conveyor rail, and then the slider slides along the lower conveyor rail to the rail connection.

[0017] Optionally, the sorting device further includes: A push claw is arranged below the intersection of the lower conveying rail and the connecting rail, and the push claw is arranged to slide vertically to push the sorting groove.

[0018] By adopting the above technical solution, the push claw is set to slide vertically upward and serves as a pushing member. When all the above sorting grooves slide along the lower conveying rail to the place where they connect to the rail, the sorting is completed and needs to be pushed upward by the push claw to cooperate with the above-mentioned corner cylinder to push the sorting groove to the upper conveying rail.

[0019] Optionally, the claw teeth portion of the spacer claw is detachably connected to the main body portion of the spacer claw.

[0020] By adopting the above technical scheme, under the premise that the claw teeth of the partition claw are arranged horizontally, reducing the number of claw teeth of the partition claw means reducing the horizontal length of the claw teeth, and increasing the number of claw teeth of the partition claw means increasing the horizontal length of the claw teeth. The horizontal length of the partition claw should be adjusted according to the spacing between each batch of food in the conveying channel. When the size of the food itself is large, the distance between each batch of food should be appropriately increased. Maintaining the original distribution length of the partition claw may cause the partition claw to be unable to effectively contact each batch of food. Therefore, the horizontal length of the partition claw is appropriately increased to increase the effective contact part; when the distance between each batch of food is small, the excessive distribution length of the partition claw will cause the partition claw and each batch of food to be unable to be transmitted alternately in an orderly manner, that is, the partition claw cannot be inserted between each batch of food as the rotating rod rotates, or the partition claw interferes with the food transmission.

[0021] In summary, the present invention has at least the following beneficial effects: 1. Since the present invention uses the separation claws on the rotating rod to cooperate with the identification component to achieve accurate sorting of food, combined with the sorting device to re-sort the food, and the gripper component to transport the food between the conveying channel and the sorting device, it solves the problems of high sorting error rate and low manual sorting efficiency in traditional solutions, thereby effectively reducing the sorting error rate and improving packaging efficiency.

[0022] 2. The present invention preferably uses a flip plate and a flip assembly thereon, so that the rotating rod, the gripper assembly, the connecting rail and the connecting rail can be flexibly switched between the horizontal state and the vertical state, which is convenient for the maintenance and repair of the equipment and the line change operation of food, and further improves the ease of use and practicality of the equipment.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-12 This application is described in further detail.

[0037] First, the embodiment of the present application discloses an automated food packaging production line device, which is applied to the automatic packaging of food in a food processing plant. Figure 1 and Figure 2An automated food packaging production line equipment includes a conveying section 8 and a packaging section 9. One end of the conveying section 8 is connected to the food production line to receive and convey the finished biscuits to the packaging section 9. Figure 1 and Figure 2 According to the conveying direction of food, the conveying section 8 mainly includes a receiving belt 81, a differential belt 82, a side sorting belt 83, a sorting belt 84, and a magnetic suspension conveyor 85, which are sequentially composed; wherein the receiving belt 81 is one end of the automated food packaging production line equipment that is connected to the food production equipment, and is used to connect and convey the food produced by the production equipment. The receiving belt 81 is a whole conveyor belt, and the finished food falls onto the receiving belt 81, and is initially and integrally conveyed by the receiving belt 81; the differential belt 82 is composed of two side belts arranged at the side edges, and the belts on both sides are conveyed in parallel to form two parallel food conveying lines, thereby improving the food conveying efficiency; the conveying speeds of the belts on both sides of the differential belt 82 are different; the differential belt 82 also includes an end belt arranged between the same end of the belts on both sides and the side sorting belt 83, the end belt is a whole belt, and the end belt can be regarded as the transition end between the side belt and the side sorting belt 83, and the food enters the end belt in sequence under the different speeds of the belts on both sides, that is, the order is sorted on the differential belt 82; the side sorting belt 8 3 is connected to the differential belt 82 to receive the food conveyance. A side sorting arm is arranged above the side sorting belt 83. The side sorting arm is formed by hingedly connecting a plurality of metal chains in sequence. Both ends of the side sorting arm are connected to the motor and are driven by the motor to freely adjust the position. One end of the side sorting arm extends to one end of the side sorting belt 83. The motor drives the side sorting belt 83 to place the food conveyed by the differential belt 82 on the belt surface. The food is arranged in a row and transported in an orderly manner with the belts on both sides of the differential belt 82. The material sorting belt 84 is arranged between the side sorting belt 83 and the magnetic suspension conveyor 8 5, the material sorting belt 84 is divided into multiple sections, and a material sorting rod is vertically arranged on each section of the material sorting belt 84. The material sorting rod is vertically arranged at a preset position, which plays a role in sorting and edge limiting during the food conveying process. An identification camera or image sensor is arranged above the material sorting belt 84. After the video is conveyed to the material sorting belt 84, it is detected whether the conveying sequence of the food is disordered or whether the food is missing; after the food is arranged in an orderly manner, the magnetic levitation conveyor 85 is used to convey the food to the packaging section 9, and the packaging is completed in the packaging section 9.

[0038] Secondly, the embodiment of the present application discloses a food automated packaging device including a food sorting device, which is applied to the packaging section of the above-mentioned food automated packaging production line equipment. Figure 3A food automatic packaging equipment including a food sorting device includes a body 1 and a fixed plate 11 arranged on the inner wall of the body 1, the fixed plate 11 is horizontally arranged above the inner bottom wall of the body 1, and one side edge of the fixed plate 11 is fixedly connected to the inner wall of the body 1, a flip plate 12 is horizontally arranged on one side of the fixed plate 11, the flip plate 12 and the fixed plate 11 are arranged in a horizontal plane, a gap is arranged between the flip plate 12 and the fixed plate 11, the gap between the flip plate 12 and the fixed plate 11 is a conveying channel 2, and the conveying channel 2 is used to convey food.

[0039] Reference Figure 3 and Figure 4 Two flipping assemblies 3 are arranged at the facing side edges of the flipping plate 12 and the fixed plate 11. The two flipping assemblies 3 connect the flipping plate 12 and the fixed plate 11 and are respectively arranged at both ends of the flipping plate 12 and the fixed plate 11. Under the connection of the flipping assemblies 3, the flipping plate 12 is supported by the fixed plate 11 and flipped with the flipping assemblies 3 as the rotation center, rotating from a horizontal state to a vertical state, and transforming the bottom side surface in the horizontal state into a vertical side surface facing away from the fixed plate 11 in the vertical state.

[0040] Under the above design, relevant personnel can open the conveying channel 2 from one side of the conveying channel 2 by flipping the flip plate 12, so as to facilitate cleaning of food residues reserved on the conveying channel 2 and related auxiliary structures to prevent them from getting moldy inside the equipment and affecting food safety.

[0041] Reference Figure 3 and Figure 4 The bottom wall of the machine body 1 is provided with a conveying bin at the part corresponding to the conveying channel 2. The length direction of the conveying bin is parallel to the conveying direction of the food. A gear is connected to the conveying bin for rotation, and a chain is meshed on it. The rotation of the gear drives the chain to transmit. The distribution direction of the chain is parallel to the length direction of the conveying bin. Multiple groups of clamps 21 are fixed to the chain. Each group of clamps 21 includes two clamps 21 distributed along the length direction of the conveying bin. The two clamps 21 of each group of clamps 21 are arranged facing each other to clamp the food in the middle part. Each group of clamps 21 clamps each batch of food that has been sorted along the length direction of the conveying bin, wherein multiple batches of food that are missorted at the front end are mixed.

[0042] Reference Figure 4 and Figure 5, a plurality of rotating rods 121 are vertically arranged and penetrated on the flip plate 12. The rotating rod 121 in this embodiment adopts a shaft sleeve rod, the shaft sleeve is fixed to the flip plate 12, and the inner center rod is supported by a bearing, and the inner center rod can rotate freely under the action of external force. The bottom of the rotating rod 121 extends to the bottom side of the flip plate 12, and a transmission gear 123 is formed. The flip plate 12 is rotatably connected to a support rod on one side of the rotating rod 121. The support rod is cylindrical, and a transmission gear 123 is also formed on it. The two transmission gears 123 are meshed for transmission. The top of the rotating rod 121 extends out of the top side of the flip plate 12, and is equipped with a magnetic wheel 122. The wheel core of the magnetic wheel 122 is fixedly connected to the center rod. A horizontally arranged metal rod is rotatably connected to the fixed plate 11. Both ends of the metal rod are sleeved and rotatably connected to the magnetic wheel 122. The fixed plate 11 is provided with a motor at one end of the metal rod. The output shaft end of the motor is close to the metal rod and is also equipped with a magnetic wheel 122. One end of the metal rod extends to the magnetic wheel 122 on the flip plate 12 close to the top of the rotating rod 121; the output shaft of the motor drives the magnetic wheel 122 to rotate, and the center rod inside the rotating rod 121 is driven to rotate through the transmission of the metal rod, and finally the support rod is driven to rotate through the gear meshing.

[0043] Reference Figure 5 , chains are meshed between the multiple transmission paper wheels 123 on the fixed plate 11 and the flip plate 12, and multiple spacer claws 124 are evenly spaced thereon. The spacer claws 124 include a claw body and multiple claw teeth 125. The multiple claw bodies are arranged horizontally, and one end is fixed to the rod wall of the support rod. The multiple claw teeth 125 are detachably connected to the end of the claw body away from the support rod; the claw body plays a supporting role, so that the claw teeth 125 can extend to the top of the conveying channel 2 with the rotation of the support rod; the transmission gears 123 meshed with the same chain rotate synchronously, driving the chain to rotate at a steady speed, and then the claw teeth 125 distributed on the chain rotate with the chain. In this embodiment, the multiple claw teeth 125 on the fixed plate 11 and the flip plate 12 are arranged relatively, that is, the claw teeth 125 distributed on the opposite sides of the two chains are relatively located and symmetrically distributed on both sides of the conveying channel 2. The claws 125 are used to fit the two side edges of the packaging bag. When the food is transported between the two claws 125, the two claws 125 cooperate with the transportation of the packaging bag to align the two side edges of the packaging bag and wrap the food. The subsequent longitudinal sealing and transverse sealing components complete the overall packaging of the food.

[0044] Reference Figure 5 The claw teeth 125 part and the claw body part are detachably connected in a bolted manner. The relevant personnel remove a claw tooth 125 by loosening the bolt. The fewer the claw teeth 125 are, the smaller the structural width of the claw teeth 125 that is rotated and extended above the conveying channel 2 is. Therefore, the claw teeth 125 part with a small number is adapted to the situation where the spacing between the clamping jaws 21 is small, and the claw teeth 125 part with a large number is adapted to the situation where the spacing between the clamping jaws 21 is large. The relevant personnel can reasonably select the number of claw teeth 125 according to the actual spacing between the clamping jaws 21 in the conveying channel 2.

[0045] The claw teeth 125 shown in the figure are partially curved, but the actual application is not limited to this shape. There are three claw teeth 125 shown in the figure, but the actual application is not limited to this number.

[0046] Replay Figure 4 When the flip plate 12 is reversed, it drives the rotating rod 121, the supporting rod and the partition claw 124 to flip together, which is convenient for relevant personnel to clean.

[0047] Reference Figure 6 The flip assembly 3 includes two side plates fixedly connected to the flip plate 12, the two side plates are vertically arranged, and two horizontal shaft rods 31 are formed on the top side; the flip assembly 3 also includes two side plates fixedly connected to the fixed plate 11, and the two side plates on the fixed plate 11 and the two side plates on the flip plate 12 are correspondingly arranged on the opposite side edges of the fixed plate 11 and the flip plate 12, and the two side plates of the fixed plate 11 are formed with a flip block on one side edge close to the flip plate 12, and the flip block is vertically arranged, and two shaft grooves are horizontally penetrated on its top side edge corresponding to the two shaft rods 31 33, two shaft rods 31 are horizontally inserted in the two shaft grooves 33, and a closing block 32 is rotatably connected above the shaft groove 33 close to the fixed plate 11 of the two shaft grooves 33, closing the shaft rod 31 inserted in the shaft groove 33 to prevent it from moving out of the shaft groove 33, so that only the shaft rod 31 can be used as the rotation center of the flip plate 12. The rotating plate rotates around the shaft rod 31 to a vertical state, and rotates from a vertical state to a horizontal state. When flipping back to the vertical state, it needs to rely on another shaft rod 31 to overlap the shaft groove 33 to support the flip plate 12.

[0048] The above-mentioned flipping process is to manually push the flip plate 12 . Thanks to the above-mentioned magnetic interval transmission method, there is no need to disassemble the mechanical transmission structure before manually pushing the flip plate 12 .

[0049] Reference Figure 3 and Figure 7 A sorting device 4 is provided in front of the partition claw 124 in the conveying direction of the conveying channel 2. The sorting device 4 is provided on the side of the flip plate 12 away from the conveying channel 2. The sorting device 4 uses a single group of clamps 21 as a unit to check whether the food on each group of clamps 21 is sorted incorrectly. If there is an error, the wrongly sorted food is taken out of the conveying channel 2, re-sorted, and then conveyed back to the conveying channel 2.

[0050] Reference Figure 3 and Figure 7The sorting device 4 includes a conveying trough 41 opened on one side of the conveying channel 2. The length direction of the conveying trough 41 is parallel to the length direction of the conveying channel 2. Two sets of tracks are horizontally arranged above the two ends of the conveying trough 41 in the length direction. The two sets of tracks are arranged in parallel, and their length directions are perpendicular to the length direction of the conveying trough 41. Two sets of fixing plates 11 are formed on both sides of the inner bottom wall of the body 1 corresponding to the two sets of tracks to fix the two sets of tracks. The two sets of tracks extend to the top of the conveying channel 2. The parts of the fixing plate 11 and the flip plate 12 corresponding to the two sets of tracks are bent upward to make way to avoid structural interference.

[0051] Reference Figure 7 The two groups of tracks are respectively an incoming track 42 and an outgoing track 43. The incoming track 42 is the track at the front end in the conveying direction, and the outgoing track 43 is the track at the rear end in the conveying direction. Both the incoming track 42 and the outgoing track 43 are provided with a gripper assembly 44. The gripper assembly 44 on the incoming track 42 slides to clamp the misordered food in the conveying channel 2 into the conveying trough 41, and the gripper assembly 44 on the outgoing track 43 conveys the sorted food back to the conveying channel 2.

[0052] Reference Figure 7 The gripper assembly 44 includes a slide bar horizontally arranged between each guide rail of the access rail 42 and the exit rail 43. The slide bar is arranged horizontally, and both ends of the slide bar are adapted to the access rail 42 and the exit rail 43. The sliding form of the slide bar along the access rail 42 and the exit rail 43 is not limited. In this embodiment, a horizontal roller 452 is adopted. The roller 452 is rotatably connected to both ends of the slide bar. The wheel surface of the roller 452 rolls along the access rail 42 and the exit rail 43, driving the slide bar to slide along the access rail 42 and the exit rail 43. In the sliding mode of the roller 452, the curved structure of the access rail 42 at both ends of the slide bar can stably clamp the slide bar on the access rail 42 and the exit rail 43.

[0053] Reference Figure 7 The gripper assembly 44 also includes an electric push rod 442 disposed at the bottom side of the slide bar. The electric push rod 442 is disposed vertically downward, and the top of its cylinder body is fixedly connected to the top of the slide bar. It slides along the access rail 42 and the access rail 43 with the slide bar. The electric push rod 442 is supported by the slide bar, and its piston rod extends downward. The piston rod end of the electric push rod 442 is fixedly connected with an electric clamping claw 441, which is disposed vertically downward, and its length direction is parallel to the length direction of the conveying channel 2. The electric clamping claw 441 slides along the access rail 42 to the top of the conveying channel 2, and slides downward driven by the electric push rod 442 to clamp the misordered food on the conveying channel 2; the gripper assembly 44 on the access rail 43 has the same structure as the gripper assembly 44 on the access rail 42, so it will not be described in detail.

[0054] Reference Figure 8Two horizontal upper conveying rails 47 are fixedly connected to the portion of the inner bottom wall of the body 1 corresponding to the top of the conveying trough 41, and two horizontal lower conveying rails 48 are fixedly connected to the opposite ends of the length direction of the conveying trough 41. The upper conveying rails 47 are parallel to the lower conveying rails 48 and are parallel to the conveying direction of the conveying channel 2. Multiple sorting grooves 45 are slidably connected to the upper conveying rail 47, and the multiple sorting grooves 45 are fitted together. The portion of the upper conveying rail 47 corresponding to the access rail 42 is to be determined, and the sorting groove 45 is the main part of the sorting device 4.

[0055] Reference Figure 8 and Fig. 9 The number of sorting slots 45 corresponds to the number of foods in each batch of foods, so that a single batch of foods is delivered to each sorting slot 45; a vertically arranged corner cylinder 451 is provided at each end of the top of the slot wall of the sorting slot 45, and the piston rod of the corner cylinder 451 is arranged horizontally, and a slider is fixed to the piston rod, and a groove is formed at the bottom of the slider, and a roller 452 is connected to rotate in the groove, and a motor for driving the roller 452 to rotate is correspondingly provided between the roller 452 and the corner cylinder 451. Thus, when the corner cylinder 451 is in operation, the piston rod of the corner cylinder 451 rotates, driving the slider to rotate. Figure 7 The horizontal state in the figure is rotated to the vertical state.

[0056] In the pending state, the length direction of the two sliders is kept horizontal so that the rollers 452 of the two sliders are adapted to the upper conveying rail 47. After the electric clamp 441 clamps a single batch of food into the sorting slot 45, the sorting slot 45 falls down in a specific order and falls onto the lower conveying rail 48. The sorting slot 45 that falls onto the lower conveying rail 48 slides along the lower conveying rail 48 to the connecting rail 43 until it slides to the bottom of the connecting rail 43. In a specific order, the sorting slot 45 slides to the bottom of the lower conveying rail 48 to obtain the correct order after correction. The falling of the sorting slot 45 is achieved by the operation of the angular cylinder 451. The piston rod of the angular cylinder 451 rotates to lift the slider to the position as shown in the figure. Figure 7 The slider is in the vertical state described in the figure, so that the slider is separated from the upper conveying rail 47, and the sorting groove 45 falls under the action of gravity. During the falling process, the piston rod of the corner cylinder 451 rotates in the opposite direction, rotating the slider back to the vertical state, so that the roller 452 on the slider is stably overlapped on the lower conveying rail 48.

[0057] Reference Figure 8 and Fig.10The inner bottom wall of the conveying groove 41 is provided with a push-up groove 46 just below the connecting rail 43. A push-up cylinder is arranged in the push-up groove 46. The push-up cylinder is arranged vertically upward. The piston rod end of the push-up cylinder is fixedly connected with a push-up plate 461. Relying on the operation of the push-up cylinder, the push-up plate 461 moves back and forth vertically; the push-up plate 461 is fixedly connected with two short plates at the two edges of the top side of the conveying channel 2. The two short plates are arranged vertically, so that a groove structure is formed between the two short plates and the push-up plate 461. When the above-mentioned multiple sorting grooves 45 all run above the pushing plate 461, the pushing cylinder pushes the pushing plate 461 to slide upward, and the multiple sorting grooves 45 are clamped by the groove-like structure, and the corner cylinders 451 on the two side edges of the sorting grooves 45 are cooperated. The sorting grooves 45 are transported from the lower conveying rail 48 back to the upper conveying rail 47, and the electric clamps 441 on the connecting rail 43 clamp the sorted food, and then the sorting grooves 45 slide along the upper conveying rail 47 to the position in the pending state.

[0058] It should be noted that the sliding speed of the sorting groove 45 on the lower conveying rail 48 must be greater than the conveying speed of the food in the conveying channel 2, so that when the food in the sorting device 4 is conveyed back to the conveying channel 2 along the connecting rail 43, it can be just re-conveyed back to the corresponding clamping claw 21 to complete the docking, thereby avoiding delays in the output efficiency of the packaging line.

[0059] The implementation principle of an automatic food packaging device including a food sorting device in an embodiment of the present application is as follows: in a pending state, the length directions of the two sliders on both sides of the sorting groove 45 remain horizontal, and the sorting groove 45 overlaps the upper conveying rail 47 and is connected to a position directly below the outgoing rail 43.

[0060] After the electric clamp 441 clamps a single batch of misordered food into the sorting trough 45, the sorting trough 45 falls onto the lower conveying rail 48 in a specific order. Specifically, the piston rod of the corner cylinder 451 rotates to lift the slider to a vertical state, so that the slider is separated from the upper conveying rail 47, and the sorting trough 45 falls under the action of gravity. During the falling process, the piston rod of the corner cylinder 451 rotates in the opposite direction to rotate the slider back to a vertical state, so that the roller 452 on the slider is stably overlapped on the lower conveying rail 48.

[0061] Then the sorting trough 45 slides along the conveying rail to the bottom of the connecting rail 43, that is, the top of the push plate 461, and then the corner cylinder 451 rotates again as described above, and cooperates with the push plate 461 to push the sorting trough 45 to the upper conveying rail 47, and the electric clamp 441 clamps the sorted food, and then the sorting trough 45 slides along the upper conveying rail 47 to the initial position in the pending state.

[0062] Based on the above-mentioned food automated packaging equipment including a food sorting device, this embodiment further discloses an identification system for identifying food automated packaging equipment, referring to Fig.11The recognition system includes a recognition component, a display unit 6, and an instruction storage unit 5.

[0063] Reference Figure 4 and Fig.11 The recognition component is arranged on the support rod, in the middle part between two adjacent spacer claws 124, and one is arranged between every two adjacent spacer claws 124. The recognition group mainly includes a 3D camera, the main part of which is embedded in the support rod and rotates synchronously with the support rod.

[0064] Reference Fig.11 and Fig.12 When a claw 124 is transported to the top of the conveyor belt, the 3D camera behind the claw 124 in the rotation direction of the support rod enters the operation state, and at the same time, the food behind the claw 124 on the conveying channel 2 enters the effective recognition range of the 3D camera. Since the rotation speed of the support rod is adapted to the transmission speed of the conveyor belt, the tangential linear velocity of the 3D camera is the same as the food conveying speed of the conveying channel 2. Therefore, in one recognition cycle, the 3D camera can maintain continuous recognition of the batch of food and improve the accuracy by increasing the recognition time.

[0065] Reference Fig.11 In the above recognition cycle, the recognition component takes pictures of all foods in a batch of foods, recognizes the different foods in the batch according to their shapes, appearances and colors, and sends the recognition results to the instruction storage unit 5. The instruction storage unit 5 stores a program of the food arrangement sequence pre-written by the technician. When the instruction storage unit 5 receives the recognition information uploaded by the recognition component, it compares it with the stored instructions inside itself. If they are consistent, it continues to operate. If they are inconsistent, it sends the relevant instructions to the control unit 7.

[0066] Reference Fig.11 The display unit 6 displays the comparison result of the identification component 126 in real time, and the relevant personnel can observe it immediately.

[0067] Reference Figure 8 and Fig.11 After the instruction storage unit 5 recognizes that the arrangement order of the food is inconsistent, it performs calculations and issues relevant instructions. The control unit 7 receives the relevant instructions from the instruction storage unit 5 and controls the sorting slot 45 to operate in a specific order.

[0068] Therefore, the specific order of the sorting slots 45 mentioned above is explained, and a single batch of food contains 5 foods as an example. Each batch of food in the instruction storage unit 5 is numbered, and the same food has the same number. For example, the correct order is 1, 1, 2, 3, 4, and the order recognized by the recognition component 126 is 1, 2, 1, 4, 3. If the recognition result received by the instruction storage unit 5 from the recognition component 126 is inconsistent with the correct order written inside, the operation order of the sorting slots 45 is calculated, and the calculated correction instruction is sent to the control unit 7. The control unit 7 numbers the corresponding sorting slots 45 according to the current order of the food according to the recognition result, and the sorting slots 45 are numbered 1, 2, 1, 4, 3.

[0069] Different sorting slots 45 in different arrangement cycles are numbered differently, all according to the order of the food in the current cycle.

[0070] The sorting slots 45 in the pending state wait for the electric gripper 441 to put the food in one by one. The sorting slot 45 with the largest number will fall onto the lower conveying rail 48 first, and the sorting slot 45 with the largest number among the remaining sorting slots 45 will fall next. The sorting slots 45 that have fallen will slide along the lower conveying rail 48 to above the push-up plate 461. After all the sorting slots 45 have slid to above the push-up plate 461, the push-up plate 461 will push all the sorting slots 45 onto the upper conveying rail 47, and the electric gripper 441 will clamp the food.

[0071] After a single sorting cycle is completed, sorting slot 45 is cleared and the pending state is restored.

[0072] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
