Description

Technical Field

[0001] This utility model relates to the field of material unloading machinery technology, and in particular to a tray separation device for sheet-like packaged products and a tray turning machine using the device. Background Technology

[0002] Luncheon meat products are ready-to-eat foods made from pork, chicken, or beef, with the addition of a certain amount of starch and spices. They are packaged in two ways: rigid and flexible. Flexible luncheon meat is produced by first filling a bag with minced meat, sealing it, placing the package on a tray, and applying planar pressure. The package is compressed and deformed into a sheet shape, filling the bag with minced meat, ultimately forming a uniformly thick sheet. After sterilization and cooling, the sheet-shaped package is unloaded and shipped out.

[0003] Currently, many downstream businesses have strict appearance requirements for the surface flatness of sheet-like packaged products. Therefore, in the production process, the trays corresponding to each packaged product have flat bottoms. As a result, after cooling, the sheet-like packaged products adhere significantly to the bottom of the trays due to the presence of moisture, making it difficult for them to detach smoothly from the trays and causing significant difficulties in unloading. To address this, the inventors used suction cups to pick up the sheet-like packaged products from the trays for unloading. However, due to the strong adhesion between the sheet-like packaged products and the trays, the success rate of suction cups was low, and unloading remained unsuccessful. Therefore, a method is needed to promote reliable separation of tray materials and facilitate the smooth unloading of sheet-like packaged products to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a tray separation device for sheet-packaged products that promotes reliable separation of tray materials and facilitates smooth discharge and unloading of sheet-packaged products, as well as a tray turning machine using the device.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a sheet-like packaged product tray material separation device, used to separate sheet-like packaged products from the slots of a tray, wherein the sheet-like packaged product includes a material part in the middle and a wing located on the side of the material part, including a top separation seat, wherein at least one separation top rod is provided on the top separation seat corresponding to each slot, the separation top rod is used to pass through the bottom edge of the slot and push the wing, and the bottom edge of the slot is provided with a pushing through hole corresponding to the separation top rod; the top separation seat and / or the tray are connected to a top separation drive mechanism.

[0006] As a preferred technical solution, the top seat is provided with the separation top rod at the four sides of the bottom of each of the slots.

[0007] The tray-turning machine using the sheet-like packaged product tray separation device includes a frame, a tray receiving frame mounted on the frame, a tray receiving conveyor mounted on the tray receiving frame for receiving and outputting the trays, a tray-turning frame located on one side of the tray receiving conveyor on the frame, and a tray-turning drive mechanism connected to the tray-turning frame; the top separation seat is mounted on the tray-turning frame, and the top of the separation top rod is not higher than the conveying surface of the tray receiving conveyor.

[0008] As a preferred technical solution, the top-off seat is fixedly mounted on the flipping frame, and the receiving frame is connected to a lifting drive mechanism for driving the receiving frame to descend, the lifting drive mechanism also serving as the top-off drive mechanism.

[0009] As a preferred technical solution, the frame is provided with a positioning device for positioning the pallet after it has been placed in place.

[0010] As a preferred technical solution, the tray tilting frame is equipped with a tray fixing device.

[0011] Thanks to the aforementioned technical solution, after cooling, when the tray containing the sheet-like packaged product in the slot reaches the top-separation seat, the top-separation drive mechanism causes the top-separation seat and the tray to move closer together. The rigid separation rod pushes the fins of the sheet-like packaged product, forcing it to separate from the bottom of the slot, ensuring reliable separation of the tray material. The separation rod only pushes the fins of the sheet-like packaged product, without pushing the central portion of the product. After separation, the shape of the sheet-like packaged product remains unchanged, ensuring its appearance. The separated sheet-like packaged product can fall directly out of the slot or fall out after flipping the tray, facilitating smooth unloading. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0022] like Figures 1 to 7 As shown in the diagram, the sheet-packaged product tray separation device is used to separate the sheet-packaged product 9 from the slot 81 of the tray 8. The sheet-packaged product 9 includes a central material section 91 and wing edges 92 located on the side of the material section 91. The material section 91 is the part containing food after being pressed into a sheet shape, and the wing edges 92 are the wing edges 92 that seal the perimeter of the packaging. The above is known technology and will not be described in detail here.

[0023] This device includes a top-separation seat 4, on which at least one separation rod 41 is provided corresponding to each of the slots 81. The separation rod 41 is used to pass through the bottom edge of the slot 81 and push the wing edge 92. The bottom edge of the slot 81 is provided with a pushing through hole 82 corresponding to the separation rod 41. The top-separation seat 4 and / or the tray 8 are connected to a top-separation drive mechanism 5.

[0024] The push-off drive mechanism 5 drives the push-off seat 4 and the tray 8 to move closer together. The separation push rod 41 passes through the push-off through hole 82 and pushes the fin edge 92. Utilizing the certain hardness of the fin itself, the rigid push of the separation push rod 41 can easily overcome the adhesive force between the sheet-like packaged product 9 and the bottom of the slot 81, pushing the sheet-like packaged product 9 away from the bottom of the slot 81. The sheet-like packaged product 9 and the tray 8 are separated. The separated sheet-like packaged product 9 can fall directly out of the slot 81 or fall out of the slot 81 after flipping over, which promotes the smooth discharge and unloading of the sheet-like packaged product 9.

[0025] The top-off drive mechanism 5 can be a drive mechanism that drives the tray 8 to move closer to the top-off seat 4, or a drive structure that drives the top-off seat 4 to move closer to the tray 8, or a drive mechanism that drives the tray 8 and the top-off seat 4 to move closer to each other at the same time. All of the above can achieve the same technical effect and are not limited here.

[0026] Preferably, the top-separating seat 4 is provided with separation rods 41 at the four sides of the bottom of each of the slots 81, thereby improving the separation effect of the sheet-like packaged product 9 through multi-point actuation at the four sides. In this embodiment, the slots 81 are rectangular, and the definition of their four sides is obvious. However, depending on the actual sheet-like packaged product 9, the slots 81 may also be circular, elliptical, or other shapes. Therefore, the aforementioned four sides should be understood as four positions arranged in a cross shape at the slots 81. More preferably, the top-separating seat 4 is provided with multiple separation rods 41 at the four sides of the bottom of each of the slots 81 to further improve the separation effect.

[0027] The tray-turning machine using the sheet-like packaged product 9 tray separation device includes a frame 1, a receiving frame 2 mounted on the frame 1, a receiving conveyor 21 for receiving and outputting the tray 8 mounted on the receiving frame 2, a tray-turning frame 3 located on one side of the receiving conveyor 21 on the frame 1, and a tray-turning drive mechanism 31 connected to the tray-turning frame 3; the top separation seat 4 is mounted on the tray-turning frame 3, and the top of the separation top rod 41 is not higher than the conveying surface of the receiving conveyor 21.

[0028] After the tray 8 containing the sheet-like packaged product 9 in the slot 81 arrives at the receiving conveyor 21, the lifting drive mechanism 5 causes the tray 8 and the lifting seat 4 to move closer to each other, and the sheet-like packaged product 9 is lifted away from the corresponding slot 81. The flipping frame 3 is driven to flip, which simultaneously causes the tray 8 to flip, and the sheet-like packaged product 9 that has left the slot 81 naturally falls to one side of the receiving conveyor 21. After the flipping frame 3 is driven back to its original position, the tray 8 falls back onto the receiving conveyor 21, which transports it away and receives the next tray 8 containing the sheet-like packaged product 9 in the slot 81.

[0029] In this embodiment, the top-separation seat 4 is fixedly mounted on the flipping tray frame 3. The receiving tray frame 2 is connected to a lifting drive mechanism 22 for driving the receiving tray frame 2 to descend. The lifting drive mechanism 22 drives the receiving tray frame 2 to descend, and the receiving tray conveying device 21 descends synchronously. The tray 8 descends along with the top-separation seat 4, causing the separating top rod 41 to passively push away the tray. Thus, the lifting drive mechanism 22 also functions as the top-separation drive mechanism 5. After pushing away the tray, the flipping tray causes the sheet-like packaged product 9 to be unloaded. After the flipping tray returns to its original position, the lifting drive mechanism 22 drives the receiving tray frame 2 to rise, and the receiving tray conveying device 21 carries the empty tray 8 to a position not lower than the top of the separating top rod 41, and then outputs it. The lifting drive mechanism 22 can be implemented using a drive cylinder or a motor in conjunction with transmission; no limitation is made here.

[0030] Of course, the top-separation seat 4 can also be movably mounted on the flipping frame 3. A lifting drive mechanism is provided between the top-separation seat 4 and the flipping frame 3. After the tray 8 is in position, the lifting drive mechanism drives the top-separation seat 4 to rise, causing it to move upwards towards the tray 8. The separation rod 41 actively pushes the sheet-like packaged product 9 away. At this time, the lifting drive mechanism that drives the top-separation seat 4 to rise also functions as the top-separation drive mechanism 5.

[0031] Based on the above structure, the lifting drive mechanism 22 is respectively arranged between the receiving frame 2 and the frame 1, and between the top-off seat 4 and the flipping frame 3, and is respectively used to drive the tray 8 to descend and drive the top-off seat 4 to rise, forming a drive for the tray 8 and the sheet-like packaged product 9 to move relative to each other simultaneously, which can achieve the same effect. All the above solutions should be within the protection scope of this utility model.

[0032] In the above scheme, the receiving conveyor 21 includes two receiving conveyor belts, which support and convey the pallet 8, and can make way for the top separation seat 4 and the separation top rod 41.

[0033] Furthermore, in this embodiment, the top-separation seat 4 is located on the flipping frame 3 and flips together with it. The separation top rod 41 will maintain the state of pushing the sheet-like packaged product 9 away from the corresponding slot 81. Thus, during the flipping process, even if there is still water at the bottom of the slot 81 and the sheet-like packaged product 9, the sheet-like packaged product 9 is not easy to lie back into the slot 81, further ensuring the smooth discharge and unloading.

[0034] Preferably, the flipping frame 3 is equipped with a tray fixing device 32. The tray fixing device 32, on the one hand, can fix the tray 8 when the separating rod 41 pushes the sheet-like packaged product 9, ensuring that all the pushing force of the separating rod 41 acts on the fins 92 of the sheet-like packaged product 9, ensuring reliable separation; on the other hand, it can keep the tray 8 fixed during the flipping process, preventing the tray 8 from falling off after flipping. The tray fixing device 32 can be implemented by using a drive cylinder to drive the pressure foot, etc.

[0035] Preferably, the frame 1 is provided with a positioning device 6 for positioning the pallet 8 after it has been placed in place. The positioning position is where the pallet 8 finally stops at the location where the separating push rod 41 can pass through the corresponding pushing through hole 82. The positioning device 6 includes a positioning stop 61 vertically movably mounted on the unloading side of the receiving conveyor 21, and the positioning stop 61 is connected to a positioning drive mechanism 62. When the pallet 8 is conveyed to the receiving conveyor 21, the positioning stop 61 is driven up by the positioning drive mechanism 62 to position the conveying front end of the pallet 8; after the pallet is flipped, the positioning stop 61 is driven down by the positioning drive mechanism 62, without affecting the output of empty pallets 8. The positioning drive mechanism 62 can be implemented using a drive cylinder or a motor, and is not limited here.

[0036] Furthermore, a positioning alignment pusher 63 is provided on the receiving side of the tray conveying device 21 on the frame 1. The positioning alignment pusher 63 is movably arranged upwards and obliquely towards the rear end of the conveying of the tray 8, and is connected to a positioning alignment drive mechanism 64. After the positioning stop 61 positions the tray 8, the positioning alignment pusher 63 is driven to rise and abut against the rear end of the conveying of the tray 8. After abutting, it and the positioning stop 61 together form the positioning of the tray 8 in the conveying direction, preventing the tray 8 from rebounding upon initial contact with the positioning stop 61 and affecting the positioning. After the separating push rod 41 pushes the sheet-like packaged product 9 away from the corresponding slot 81, the positioning alignment pusher 63 is driven to fall back.

[0037] In this embodiment, when the tray 8 containing the sheet-like packaged product 9 in the slot 81 reaches the top separation seat 4, the top separation drive mechanism 5 drives the top separation seat 4 and the tray 8 to move closer together. The rigid separation push rod 41 pushes the wing edge 92 of the sheet-like packaged product 9, forcing it to separate from the bottom of the slot 81, ensuring reliable separation of the tray material. The separation push rod 41 pushes only the wing edge 92 of the sheet-like packaged product 9, without pushing the central food portion 91 of the product. After separation, the shape of the sheet-like packaged product 9 remains unchanged, ensuring the product's appearance. The separated sheet-like packaged product 9 can fall directly out of the slot 81 or fall out of the slot 81 after flipping the tray, facilitating smooth unloading of the sheet-like packaged product 9.
