Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to an automatic suction tray and material stacking device. Background Technology

[0002] In food processing, such as making buns, dumplings, biscuits, and pastries, a large number of items are produced, requiring tray placement. Currently, tray placement is mainly done manually, which is inefficient and labor-intensive. While some automated tray placement machines have emerged to address these issues, these machines primarily place food on baking trays for later baking. The trays, due to their weight, can be separated and transported via conveyor belts. However, for some foods, such as frozen pastries, which are directly trayed and packaged, the trays are lightweight and stacked, making it impossible for them to fall to the tray placement station under their own weight. Manual placement of the trays is necessary, which is cumbersome. Therefore, there is an urgent need to develop an automated tray placement and conveying device that reduces manual labor and increases efficiency, overcoming the shortcomings of current applications and meeting current needs. Utility Model Content

[0003] The purpose of this invention is to provide an automatic tray-feeding and stacking device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic tray stacking device includes a frame, a telescopic conveyor belt, a storage rack, trays, a tray conveying mechanism, and an automatic picking mechanism. The telescopic conveyor belt is mounted on the frame, and the storage rack is fixed to the left side of the telescopic conveyor belt on the frame. Multiple trays are stacked in the storage rack. An automatic picking mechanism facing the multiple trays is provided at the bottom of the storage rack. The tray conveying mechanism is mounted in the frame below the automatic picking mechanism. The automatic picking mechanism includes a cylinder, a base plate, and pneumatic suction cups. The cylinder is fixed to the frame, and the telescopic end of the cylinder is fixed to the base plate. Multiple pneumatic suction cups are fixedly mounted on the base plate.

[0006] Preferably, the telescopic conveyor belt includes: a transmission belt, a first rotating roller, a tensioning roller, a drive roller, a first motor, a first transmission shaft, a second transmission shaft, a first synchronous pulley, a first synchronous belt, a first slide rail, a second synchronous pulley, a second synchronous belt, a second motor, a first gear, a second gear, a second slide rail, a second slider, a transfer frame, a second rotating roller, a connecting plate, a first slider, a lifting frame, and a lifting roller. The first rotating roller and the drive roller pass through the transmission belt and are rotatably connected within the frame. Multiple tensioning rollers for tensioning the transmission belt are rotatably connected within the frame. The first motor is fixed within the frame, and a second synchronous pulley is fixed to the output shaft of the first motor. A second synchronous pulley is also fixed to the drive roller. The two second synchronous pulleys are connected by a second synchronous belt. The first slide rail is vertically fixed within the frame, and a first slider is slidably mounted on the first slide rail. A lifting frame is fixedly connected to the front side of the first slider. Two lifting rollers that pass through the conveyor belt are rotatably connected to the lifting frame. A first drive shaft and a second drive shaft are rotatably connected inside the frame. A first synchronous pulley is fixed on each of the first and second drive shafts. The two first synchronous pulleys are connected by a first synchronous belt. A second motor is fixed inside the frame. A first gear is fixed on the output shaft of the second motor. A second gear that meshes with the first gear is provided on one side of the first gear. The second gear is fixed on the first drive shaft. A second slide rail is horizontally fixed inside the frame. A second slider is slidably mounted on the second slide rail.

The three first rotating shafts and two second rotating shafts are connected by transmission wheels and transmission belts. The third motor is fixed inside the frame, and the output shaft of the third motor is fixed to one of the first rotating shafts.

[0008] Preferably, a PLC controller is installed on the frame.

[0009] The beneficial effects of this utility model are as follows: In use, the automatic tray-stacking and material-stacking device first stacks multiple trays into the storage rack. Then, a cylinder drives a base plate and a pneumatic suction cup to rise, causing the pneumatic suction cup to adhere to the bottom tray in the storage rack. The pneumatic suction cup is then activated to hold the tray in place. Next, the cylinder drives the base plate and the pneumatic suction cup to move downwards, causing the pneumatic suction cup to pull the bottom tray out of the storage rack. Then, the pneumatic suction cup is deactivated, releasing the tray. The tray falls onto the conveyor belt under gravity, and a third motor drives the conveyor belt to rotate, transporting the tray forward. The automatic material-retrieving mechanism then retrieves the next tray, and this process is repeated. In summary, this utility model automatically places and transports trays, reducing manual operation and increasing work efficiency. Attached Figure Description

On the frame 1, the telescopic end of the cylinder 701 is fixed to the base plate 702. Multiple pneumatic suction cups 703 are fixedly installed on the base plate 702. In use, the cylinder 701 first drives the base plate 702 and the pneumatic suction cups 703 to be lifted upward, so that the pneumatic suction cups 703 stick to the bottom tray 5 in the storage rack 4. Then, the pneumatic suction cups 703 are activated to suck it up. Then, the cylinder 701 drives the base plate 702 and the pneumatic suction cups 703 to be moved downward, so that the pneumatic suction cups 703 suck the bottom tray 5 in the storage rack 4 downward. Then, the pneumatic suction cups 703 are closed to release the tray 5. The tray 5 falls onto the tray conveying mechanism 6 by gravity. The tray conveying mechanism 6 then transports the tray 5 forward.

[0024] The telescopic conveyor belt 3 includes: a conveyor belt 301, a first rotating roller 302, a tensioning roller 303, a drive roller 304, a first motor 305, a first drive shaft 306, a second drive shaft 307, a first synchronous pulley 308, a first synchronous belt 309, a first slide rail 310, a second synchronous pulley 311, a second synchronous belt 312, a second motor 313, a first gear 314, a second gear 315, a second slide rail 316, a second slider 317, a transfer frame 318, a second rotating roller 319, a connecting plate 320, a first slider 321, a lifting frame 322, and a lifting roller 323. The first rotating roller 302 and the drive roller 304 pass through the conveyor belt 301 and are rotatably connected to the frame 1. Multiple tensioning rollers for the conveyor belt 301 are rotatably connected within the frame 1. The tension roller 303 and the first motor 305 are fixed inside the frame 1.

Two lifting rollers 323 that pass through the conveyor belt 301 are rotatably connected to the lifting frame 322. A first drive shaft 306 and a second drive shaft 307 are rotatably connected inside the frame 1. A first synchronous pulley 308 is fixed on both the first drive shaft 306 and the second drive shaft 307. The first synchronous pulleys 308 are connected by a first synchronous belt 309. The second motor 313 is fixed inside the frame 1. A first gear 314 is fixed on the output shaft of the second motor 313. A second gear 315 meshes with the first gear 314 on one side. The second gear 315 is fixed on the first transmission shaft 306. The second slide rail 316 is laterally fixed inside the frame 1. A second slider 317 is slidably mounted on the second slide rail 316. A transfer frame 318 that passes through the transmission belt 301 is fixed to the front side of the second slider 317. A second roller 319 for supporting the transmission belt 301 is rotatably connected to the transfer frame 318. A connecting plate 320 that is fixed to the first synchronous belt 309 is fixed to the rear side of the transfer frame 318. In use, the first synchronous pulley 308 is connected by a first synchronous belt 309. Machine 305 drives drive roller 304 to rotate, which in turn drives conveyor belt 301 to rotate, thus conveying materials. Additionally, second motor 313 drives first gear 314 and second gear 315 to rotate, which in turn drives first drive shaft 306 to rotate. First drive shaft 306 then drives first synchronous belt 309 to rotate, which in turn drives connecting plate 320, adapter frame 318, and second roller 319 to move laterally. When second roller 319 moves to the left, it causes conveyor belt 301 to extend to the left. At this time, under the action of conveyor belt 301, lifting roller 323 moves upward, which in turn drives first slider 321 and lifting frame 322 to move upward.When the second roller 319 moves to the right, the conveyor belt 301 shortens to the right, causing the first slider 321, the lifting frame 322, and the lifting roller 323 to move downwards under the influence of gravity.

[0025] The tray conveying mechanism 6 includes: a third motor 601, a first rotating shaft 602, a transmission belt 603, a second rotating shaft 604, and a transmission wheel 605. Three first rotating shafts 602 and two second rotating shafts 604 are rotatably connected inside the frame 1. The three first rotating shafts 602 and two second rotating shafts 604 are connected by transmission wheel 605 and transmission belt 603. The third motor 601 is fixed inside the frame 1. The output shaft of the third motor 601 is fixed to one of the first rotating shafts 602. In use, the third motor 601 drives the first rotating shaft 602, transmission belt 603, second rotating shaft 604, and transmission wheel 605 to rotate.

[0026] A PLC controller 2 is installed on the rack 1, which controls various electrical components.

[0027] Working Principle: In operation, this automatic tray stacking device works as follows: First, a person stacks multiple trays 5 into the storage rack 4. Then, a cylinder 701 drives the base plate 702 and pneumatic suction cup 703 upwards, causing the pneumatic suction cup 703 to adhere to the bottom tray 5 within the storage rack 4. The pneumatic suction cup 703 is then activated to hold the tray 5 in place. Next, the cylinder 701 drives the base plate 702 and pneumatic suction cup 703 downwards, causing the pneumatic suction cup 703 to pull the bottom tray 5 out of the storage rack 4. Finally, the pneumatic suction cup 703 is deactivated, releasing the tray 5. The tray 5, under gravity, falls onto the transmission belt 603. A third motor 601 drives the transmission belt 603 to rotate, thus transferring the tray 5 to the storage rack 4. Box 5 is conveyed forward, and then the automatic material handling mechanism 7 picks up the next tray box 5. This process is repeated. In addition, materials such as buns and pastries will move forward along the telescopic conveyor belt 3 from the right end. When they reach the left end of the conveyor belt, the transfer frame 318 and the connecting plate 320 are moved to the right by the PLC controller 2. Because the materials are driven to the left by the conveyor belt, the materials fall into the tray box 5 from the left end of the telescopic conveyor belt 3 in sequence. Moreover, the length of the telescopic conveyor belt 3 is extended and retracted during the conveying process so that the materials fall into different positions in the tray box 5. The principle is not elaborated here. For the principle, please refer to patent CN209112876U, a horizontal tray-laying machine, which aims to make materials such as buns and pastries fall into the tray box 5 in sequence.
