[0044] During the mooncake production process, after the mooncakes are formed, they are usually automatically and orderly arranged on baking trays using an automatic tray-arranging machine. After being taken out and placed on a storage cart to rest for a period of time, water is sprayed on the surface of the mooncakes, and then they are left to rest before being sent to the oven. Currently, there is no complete connection, and manual intervention is required between each work section to complete the entire process. Tasks such as placing baking trays into the automatic tray-arranging machine, taking baking trays out of the automatic tray-arranging machine and placing them on the storage cart, and sending baking trays into the tunnel oven are usually done manually, requiring a large amount of manual labor to cooperate, resulting in low mooncake processing efficiency and requiring a large amount of labor costs. In addition, a large number of people walking around and moving storage carts occupy the production workshop area, resulting in low space utilization and is not conducive to food safety control. This embodiment provides a food processing conveyor line that effectively solves the technical problems of low food processing efficiency and high food safety risks in the prior art.

[0045] See also Figures 1-11, an embodiment of the present application provides a food processing conveyor line, including a main conveying mechanism and a sub-conveyor mechanism; the main conveying mechanism includes an upper main conveying line 1 and a lower main conveying line 2; the sub-conveyor mechanism includes an upper sub-conveyor line 3, a lower sub-conveyor line 4, a tray arranging machine 5, a limiting mechanism 6 and a tray pushing mechanism 7; the upper main conveying line 1 is used to place a pallet for transportation, and the pallet on the upper main conveying line 1 is blocked by the limiting mechanism 6 and pushed to the upper sub-conveyor line 3 by the tray pushing mechanism 7; the upper sub-conveyor line 3 is used to convey the pallet to the tray arranging machine 5, the tray arranging machine 5 is used to arrange food on the pallet and convey the pallet to the lower sub-conveyor line 4, and the lower sub-conveyor line 4 is used to convey the pallet to the lower main conveying line 2.

[0046] This embodiment can be applied to the processing and conveying operations of food (such as moon cakes), and can also be applied to the processing and conveying operations of other objects. This embodiment will not be described in detail one by one.

[0047] More specifically, multiple rollers are installed on the upper main conveyor line 1, the lower main conveyor line 2 and the upper sub-conveyor line 3. The motor drives the rollers to rotate and the pallets can be moved on each conveyor line. Figure 4 Arrow A indicates the conveying direction of the pallets between the upper main conveyor line 1, the upper sub-conveyor line 3 and the pallet arrangement machine 5. Figure 5 Arrow B indicates the conveying direction of the pallets between the tray arranging machine 5, the lower sub-conveyor line 4 and the upper main conveyor line 1; when the upper sub-conveyor line 3 includes a first conveyor line and a second conveyor line connected vertically, the first conveyor line is connected to the upper main conveyor line 1, and the pallets on the upper main conveyor line 1 are pushed to the first conveyor line through the limiting mechanism 6 and the tray pushing mechanism 7, and the second conveyor line is connected to the tray arranging machine 5. A tray feeding mechanism 91 can be provided on the second conveyor line to push the pallets on the first conveyor line to the tray arranging machine 5 through the tray feeding mechanism 91; the tray arranging machine 5 can freely modify the parameters such as the number of mooncakes placed and the diameter of the mooncakes according to user needs, and automatically arrange the mooncakes on the tray; the tray arranging machine 5 also has a tray crawler, which can transport the pallets with mooncakes to the tray inlet 832 of the lower sub-conveyor line 4; an electrical box 92 is also provided on the food processing conveyor line, which is convenient for connecting to various devices and providing power to various devices. A start and stop button is provided on the electrical box 92 to facilitate the staff to start and stop the entire processing conveyor line.

[0048] In this embodiment, the upper main conveyor line 1 and the upper branch conveyor line 3 and the limiting mechanism 6 and the tray pushing mechanism 7 that cooperate with the two can automatically convey trays to the tray arranging machine 5, and the trays of food arranged by the tray arranging machine 5 can be transported to the next operation point through the lower main conveyor line 2 and the lower branch conveyor line 4. The entire process does not require human intervention, and the automated processing and transportation of food is realized. It can not only improve the space utilization rate of the workshop and be beneficial to food safety control, but also improve the transportation efficiency and processing efficiency of food, reduce the manpower utilization rate and labor cost during food processing, and effectively solve the technical problems of low food processing efficiency and food safety hazards in the prior art.

[0049] Furthermore, in this embodiment, multiple sub-conveyor mechanisms are arranged side by side on one side of the main conveyor mechanism. Empty trays can be transported to each sub-conveyor mechanism via the same upper main conveyor line 1, allowing the traying machines 5 of each sub-conveyor mechanism to simultaneously tray food. The trays, after being trayed, are then returned to the same lower main conveyor line 2, allowing the lower main conveyor line 2 to transport all trays to the next workstation. This provides the advantages of small footprint and high processing efficiency.

[0050] More specifically, the feed end of the upper main conveyor line 1 can be connected to a tray placing device dedicated to the pallet, and the tray placing device can provide empty pallets for the upper main conveyor line 1 so that the empty pallets can be transported to various sub-conveyor mechanisms; in the processing and production of mooncakes, the food processing conveyor line can also include a buffer tower (a water spray mechanism can be provided in the middle of the buffer tower to wet the surface of the mooncakes), a tunnel furnace, a drying tower, a cake-plate separation line, a mooncake packaging line and a pallet recovery line, all of which are connected by conveyor belts. The mooncakes on the pallet can be sequentially subjected to static relaxation in the buffer tower, baking in the tunnel furnace, drying and cooling in the drying tower, cake-plate separation and packaging into products, and the pallets separated by the cake-plate separation line are transported to the tray placing device through the pallet recovery line to participate in the next round of mooncake processing operations, thereby realizing a complete mooncake processing production line, and each link adopts a conveying and operating method, without the need for human intervention, to realize the automated processing of mooncakes, effectively improving the processing efficiency of mooncakes.

[0051] Furthermore, in this embodiment, a control system is also included, which is used to control each of the limiting mechanisms 6 and the tray pushing mechanisms 7 so that the trays on the upper main conveyor line 1 are respectively transported to each of the upper sub-conveyor lines 3. By controlling and activating each of the limiting mechanisms 6 and the tray pushing mechanisms 7, the control system can ensure the uniformity of the trays delivered to each of the upper sub-conveyor lines 3, ensuring that each sub-conveyor mechanism can participate in the operation at the maximum frequency, which is conducive to improving food processing efficiency.

[0052] More specifically, when a multi-component delivery mechanism is used, a control program needs to be set for the control system; Figure 1 The structure of a four-component conveying mechanism is adopted. The tray placing device places a group of pallets (four pallets in a group) at a time, and the tray placing device places the pallets on the upper main conveyor line 1 at the same frequency, and the distance between two adjacent pallets on the upper main conveyor line 1 is equal to the distance between adjacent sub-conveyor mechanisms; a sensor can be provided on the third sub-conveyor mechanism to sense the position of the pallets on the upper main conveyor line 1; when the first pallet of a group passes the sensor, the control system can control the limiting mechanism 6 of the four-component conveying mechanism to descend to a certain height. At this time, there are four pallets on the upper main conveyor line 1 and the four pallets have not reached the connection between each sub-conveyor mechanism and the upper main conveyor line 1. When the four pallets are blocked by the corresponding limiting mechanism 6, the control system can control the corresponding pushing mechanism 7 to push the pallets to the corresponding upper sub-conveyor line 3. When the pallets enter the upper sub-conveyor line 3, the control system can control each limiting mechanism 6 and the pushing mechanism 7 to restore the initial position, and the control system can control the tray placing device to place the next group of pallets. Repeating the above steps can ensure the uniformity of the pallets delivered to each upper sub-conveyor line 3. Of course, the control system may also adopt other control programs that can ensure the uniformity of the pallets delivered to each upper sub-conveyor line 3, which will not be described in detail in this embodiment.

[0053] Furthermore, in this embodiment, the limiting mechanism 6 is arranged directly above the upper main conveyor line 1; the limiting mechanism 6 includes a limiting cylinder 61 and a stopper 62. The telescopic rod of the limiting cylinder 61 is connected to the stopper 62, and the limiting cylinder 61 controls the up and down movement of the stopper 62. When the tray is about to reach the connection between the upper main conveyor line 1 and the upper sub-conveyor line 3, the limiting cylinder 61 is activated to control the telescopic rod to extend and retract downward so that the stopper 62 moves downward to a certain height. The stopper 62 blocks the tray so that the tray no longer moves along the conveying direction of the upper main conveyor line 1. Then, the tray pushing mechanism 7 is activated to push the blocked tray to the corresponding upper sub-conveyor line 3. The upper sub-conveyor line 3 then conveys the tray to the tray arranging machine 5, thereby automatically conveying empty trays to the tray arranging machine 5 without manual intervention, which is conducive to improving food processing efficiency.

[0054] Furthermore, in this embodiment, the tray pushing mechanism 7 includes a lifting cylinder 72, a pushing piece 73, a sliding seat 75, a first bracket 71 and a pushing assembly 74; the pushing assembly 74 is installed on the first bracket 71, and the pushing assembly 74 pushes the sliding seat 75 to move along the conveying direction of the upper sub-conveyor line 3; the lifting cylinder 72 is installed on the sliding seat 75, and the telescopic rod of the lifting cylinder 72 is connected to the pushing piece 73, and the lifting cylinder 72 drives the pushing piece 73 to move up and down. When the limit cylinder 61 controls the blocking member 62 to move downward to block the tray, the lifting cylinder 72 is started to control the telescopic rod to extend and retract downward so that the pushing member 73 moves downward to a certain height, and then the pushing assembly 74 is started to drive the sliding seat 75 to move in the direction close to the upper sub-conveyor line 3, thereby driving the entire lifting cylinder 72 to move in the direction close to the upper sub-conveyor line 3, and the pushing member 73 can push the tray blocked by the limit mechanism 6 to move in the direction of entering the upper sub-conveyor line 3 until the entire tray completely enters the upper sub-conveyor line 3, and the upper sub-conveyor line 3 then conveys the tray to the tray arranging machine 5, thereby realizing automatic delivery of empty trays to the tray arranging machine 5 without manual intervention, which is conducive to improving food processing efficiency.

[0055] More specifically, each time a pallet is pushed to the upper sub-conveyor line 3, the corresponding limiting mechanism 6 and the tray pushing mechanism 7 need to be restored to their initial positions to prepare for the next pallet conveyance; the limiting cylinder 61 is fixedly mounted on the first bracket 71; when the upper sub-conveyor line 3 is provided with a tray feeding mechanism 91, the structure of the tray feeding mechanism 91 is consistent with the structure of the tray pushing mechanism 7, and the tray feeding mechanism 91 includes a second bracket, a sliding assembly, a mounting seat, a tray feeding cylinder and a tray feeding member. The sliding assembly is arranged on the second bracket, and the tray feeding member is controlled to descend to a certain height by the tray feeding cylinder, and then the mounting seat is pushed to move on the second bracket by the sliding assembly. The mounting seat drives the tray feeding cylinder to move in a direction close to the tray arranging machine 5, so that the tray feeding member can push the pallet of the upper sub-conveyor line 3 to the tray arranging machine 5.

[0056] Furthermore, in this embodiment, the upper main conveyor line 1 is arranged directly above the lower main conveyor line 2, and the upper sub-conveyor line 3 is arranged directly above the lower sub-conveyor line 4. This arrangement allows the upper main conveyor line 1 and the lower main conveyor line 2 to be arranged at the same vertical position, and the upper sub-conveyor line 3 and the lower sub-conveyor line 4 to be arranged at the same vertical position, which can effectively reduce the floor space of the entire food processing conveyor line, save space when the food processing conveyor line is installed, and meet the installation requirements of the factory.

[0057] Furthermore, in this embodiment, a lifting conveyor device 8 is provided on the lower sub-conveyor line 4. The lifting conveyor device 8 is used to guide the pallets into the lower sub-conveyor line 4 and convey the pallets to the lower main sub-conveyor line. The lifting conveyor device 8 can guide the pallets that have been arranged into trays into the lower sub-conveyor line 4 and neatly convey them to the lower main conveyor line 2, thus completing the smooth transition of the pallets between the tray arrangement machine 5, the lower sub-conveyor line 4, and the lower main conveyor line 2.

[0058] Furthermore, in this embodiment, the lifting and conveying device 8 includes a conveying frame 83, a first motor 81, a second motor 82, a roller 84, a lifting cylinder 85 and a transmission assembly; the roller 84 is rotatably installed on the conveying frame 83, and the second motor 82 drives the roller 84 to rotate; the transmission assembly includes a support member 86 and an endless chain 87, the first end of the support member 86 is hinged to the conveying frame 83, and the second end of the support member 86 is driven up and down by the lifting cylinder 85; a plurality of first gears 861 are rotatably installed on the support member 86, and the plurality of first gears 861 are connected by a endless chain 87, the conveying direction of the endless chain 87 is the same as the length direction of the roller 84, and the first motor 81 drives any one of the first gears 861 to rotate.

[0059] The lifting conveyor device 8 guides the pallet to move along the conveying direction of the pallet crawler of the pallet arranging machine 5 through the rotating roller 84 so that the pallet can be completely moved to the conveying frame 83, and the second end of the support 86 is lifted by the lifting cylinder 85, so that the ring chain 87 rises to a horizontal state. At this time, the upper chain of the ring chain 87 contacts and abuts the bottom of the pallet. The rotating first gear 861 and the ring chain 87 can drive the pallet to move along the conveying direction of the ring chain 87 to the lower main conveyor line 2, so that the pallet that has been arranged can be smoothly gathered from each sub-conveyor mechanism to the lower main conveyor line 2, which is conducive to ensuring the smoothness and efficiency of pallet transportation and avoiding the problem of non-smooth transportation at the intersection of each conveyor line.

[0060] More specifically, a stopper 831 is provided on each side of the conveyor frame 83. Each stopper 831 is provided with a tray entry opening 832. The extension direction of the tray entry opening 832, the conveying direction of the roller 84, and the conveying direction of the pallet tracks are all aligned. The top of the stopper 831 is higher than the highest point of the roller 84 and the horizontal endless chain 87. The width of the tray entry opening 832 is slightly greater than the length of the corresponding side of the pallet. The two stoppers 831 are arranged in parallel, and the distance between them can be slightly greater than the length of the other side of the pallet. Pallets can enter the conveyor frame 83 through the tray entry opening 832 and, driven by the rotation of the roller 84, can quickly and completely enter the conveyor frame 83 in the direction of entry (i.e., the conveying direction of the roller 84). The two stoppers 831 not only prevent pallets from falling off the sides of the conveyor frame 83, but also effectively limit the pallets from swinging during movement, thereby ensuring that the pallets are transported neatly to the lower main conveyor line 2.

[0061] Furthermore, in this embodiment, the end of the ring chain 87 along the conveying direction is exposed from the conveying frame 83 and extends into the lower main conveying line 2. Figure 7 The extended section 871 of the endless chain is arranged outside the conveyor rack 83. Driven by the endless chain 87, the pallets on the conveyor rack 83 are gradually discharged from the conveyor rack 83, and the extended section 871 of the endless chain can continue to provide power for the pallets protruding from the conveyor rack 83 to continue moving in the current direction, which not only helps the pallets to quickly detach from the conveyor rack 83, but also facilitates the rapid movement of the entire pallet to the lower main conveyor line 2.

[0062] More specifically, when the endless chain 87 is horizontal, the top of the endless chain 87 is no lower than the highest point of the roller 84, ensuring that the raised endless chain 87 can contact the bottom of the pallet. The second end of the support member 86 protrudes from the conveyor frame 83. The protruding portion of the support member 86 is also equipped with a rotatable first gear 861. The first gear 861 is rotatably connected to the support member 86 via a center rod and a bearing. The extended section 871 of the endless chain is sequentially wrapped around the outer circumference of each first gear 861.

[0063] Furthermore, in this embodiment, the transmission assembly comprises at least two groups, and a plurality of rollers 84 are provided. The rollers 84 and the endless chains 87 are staggered on the conveyor frame 83. The staggered rollers 84 and the endless chains 87 can jointly support the pallets moving on the conveyor frame 83. In particular, when the endless chains 87 are in operation, the rollers 84 can effectively reduce the load-bearing capacity of the conveyor chain, not only ensuring that the endless chains 87 can properly transport the pallets, but also effectively protecting the endless chains 87, thereby extending the service life of the endless chains 87.

[0064] More specifically, different groups of support members 86 can be connected by connecting rods, and the telescopic end of the lifting cylinder 85 is provided with a lifting platform. Different groups of support members 86 are all connected to the lifting platform. This arrangement can bundle and fix each support member 86 together and synchronously lift two groups of ring chains 87 through the lifting platform; different groups of first gears 861 are connected through a transmission shaft, and the first motor 81 drives the transmission shaft to rotate, which can drive different groups of first gears 861 to rotate synchronously, and then drive different groups of ring chains 87 to rotate synchronously, so that the two ring chains 87 can synchronously transport the pallet; each roller 84 is provided with a second gear, and the second gear is connected through the first chain 841 for transmission, and the second motor 82 is connected to any second gear. The second gear and the first chain 841 can be rotated by the second motor 82, thereby driving each roller 84 to rotate synchronously; the bottom of the conveying frame 83 is provided with a support foot 833 with adjustable height. The bottom of the support legs 833 may be provided with an adjusting bolt, and the height of each support leg 833 may be adjusted by rotating the adjusting bolt, which is beneficial for adjusting each support leg 833 to have the same height to support the conveyor rack 83, and is beneficial for ensuring the balance of the conveyor rack 83. Figure 11 In this embodiment, two sets of ring chains 87 and three sets of rollers 84 are preferably used. The staggered rollers 84 and ring chains 87 can also effectively reduce the gap on the conveying surface of the conveyor frame 83, which is beneficial to avoid the edge of the pallet being stuck in the gap and affecting the normal transportation of the pallet on the conveyor frame 83.
