Description

Technical Field

[0001] The present invention relates to the technical field of fast food box production, and particularly relates to a palletizing device for fast food box production. Background Art

[0002] A fast food box is a disposable container for holding fast food. It can highly adapt to the modern fast-paced life. It is convenient to carry, allowing consumers to dine anywhere at any time. Moreover, being disposable, it can effectively reduce cross-contamination and ensure hygienic safety. At the same time, it has a low cost and is suitable for large-scale production to meet the needs of the catering industry.

[0003] When producing fast food boxes, in order to facilitate the collection and processing of fast food boxes, palletizing is usually carried out after the production of fast food boxes is completed. Since the fast food boxes are light in texture, the structural stability during palletizing is poor. Traditionally, when palletizing by placing, it is necessary to completely remove the air between the upper and lower layers. And for palletizing by free fall, the air between the fast food boxes is not pressed out, which affects the palletizing quality. Manual palletizing will also result in non-uniform pressing force during palletizing, causing the gaps between the fast food boxes after palletizing to be inconsistent, resulting in wasted space or the fast food boxes being damaged by pressing. Also, manual operation increases the probability of the fast food boxes being contaminated. Therefore, there is currently a lack of an effective palletizing device for this type of fast food box product.

[0004] Based on this, a palletizing device for fast food box production is proposed. Summary of the Invention

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] Please refer to Figures 1 - 5 , the present invention provides a technical solution: A fast food box production and palletizing device includes an operating table 1. A conveyor belt 2 is connected to the operating table 1. The fast food boxes can be transported along with the conveyor belt 2. When the fast food boxes are moved to one end of the conveyor belt 2, their structures will be blocked by the protective edge at one end of the conveyor belt 2 and stop moving forward. At this time, the fast food boxes wait for the suction cup 8 to transfer and transport them for palletizing. A translation track 6 is slidably connected to one side of the operating table 1. A lifting bar 7 is slidably connected to the translation track 6. The lower end of the lifting bar 7 is connected to a suction cup 8. The suction cup 8 is interconnected with an air pump through an air pipe. The operating state of the air pump is related to the position of the suction cup 8. When the suction cup 8 is above the conveyor belt 2, the air pump operates to inhale. When the suction cup 8 moves to the placement table 10, the air pump stops operating, and the fast food box adsorbed on the suction cup 8 can be placed on the placement table 10. A second chute 5 is provided on the operating table 1. One side of the lifting bar 7 is connected to a second sliding rod 30. The second sliding rod 30 is slidably connected to the second chute 5. The second chute 5 is a track with both ends slanting downward and the middle being horizontal. The two ends slanting downward are respectively convenient for the suction cup 8 to adsorb the fast food box and for the suction cup 8 to place the fast food box on the placement table 10; One side of the operating table 1 is connected to a palletizing cylinder 9. A placement table 10 is slidably connected to the palletizing cylinder 9. A handle 11 is connected to the outside of the placement table 10. The structure of the handle 11 is slidably connected to the palletizing cylinder 9. One side of the placement table 10 is connected to a toothed block 12. A deflection shaft 29 is rotatably connected to the operating table 1. The connection between the deflection shaft 29 and the operating table 1 is a rotational connection, and the structures at the connection are tightly abutted against each other. Without external force, the deflection shaft 29 is not likely to rotate. When the gear 13 is affected by the placement table 10 and the toothed block 12, the deflection shaft 29 still will not rotate. A ratchet 31 and a gear 13 are connected to the deflection shaft 29. The structure of the ratchet 31 enables the deflection shaft 29 to only rotate in one direction. A deflection rod 14 is rotatably connected to the deflection shaft 29. A connecting rod 33 is connected to the deflection rod 14. A pawl 32 and a torsion spring 34 are connected to the connecting rod 33. The setting of the structure of the torsion spring 34 can ensure that the pawl 32 always deflects towards the ratchet 31. The pawl 32 is rotatably connected to the connecting rod 33, and one end of the torsion spring 34 is connected to the pawl 32 and the other end is connected to the connecting rod 33. A pushing member for pushing the deflection rod 14 to return to its original position is provided below the deflection rod 14; A transmission mechanism is connected to the operating table 1 to first drive the suction cup 8 to transfer the fast food box to the placement table 10 and then drive the placement table 10 to lower in height. After the fast food box is driven by the suction cup 8 and placed on the placement table 10, then the placement table 10 lowers in height. Subsequently, the suction cup 8 transfers another fast food box and presses it on the previous fast food box. That is, the fast food boxes alternate between transfer and palletizing. During equipment installation, the height that the placement table 10 descends each time can be adjusted so that it is the same as the thickness of the fast food box, improving the palletizing quality of the fast food boxes and ensuring that the fast food boxes can be evenly butted and palletized together.

[0020] Specifically, as Figure 1As shown in the figure, a first slide bar 4 is connected to the outside of the workbench 1, and the translation track 6 is slidably connected to the first slide bar 4. By setting the first slide bar 4, the stability of the horizontal movement of the translation track 6 is ensured. A first slide rod 22 is also provided on one side of the translation track 6, further improving the stability of the structure translation.

[0021] Specifically, as Figure 1 shown, the pushing member includes an L-shaped frame 35. The lower end of the L-shaped frame 35 is connected to the workbench 1 through a return spring 16. A limiting cylinder 15 is provided outside the return spring 16 and the L-shaped frame 35. The return spring 16 can push the deflection rod 14 to return after deflection when the deflection rod 14 is not affected by external forces. The long rod structure at the upper end of the L-shaped frame 35 is to ensure that when the pivot shaft 29 is drawn out, the abutting state between the deflection rod 14 and the L-shaped frame 35 will not disappear, and it is also convenient for the subsequent reset of the pivot shaft 29 structure.

[0022] Specifically, as Figure 1 、 Figure 2 and Figure 4 shown, the transmission mechanism includes a fourth slide rod 26. A fourth chute 25 is provided on the workbench 1. The fourth slide rod 26 is rotatably connected to a main cylinder 27, and the main cylinder 27 is rotatably connected to the workbench 1. After the main cylinder 27 is started, it will be in a reciprocating telescopic state until the number of fast food boxes stacked in the stacking cylinder 9 reaches the upper limit. At this time, the operator needs to manually stop the main cylinder 27, and then collect the stacked fast food boxes. Each reciprocating telescopic movement of the main cylinder 27 completes the stacking of one fast food box. Therefore, the main cylinder 27 can also be set to automatically stop running after reciprocating and telescoping a certain number of times. A translation block 18 is slidably connected to one side of the workbench 1. A chute block 20 is slidably connected to one side of the translation block 18. The fourth slide rod 26 is slidably connected to the chute block 20. A docking spring 36 is connected between the chute block 20 and the translation block 18. The docking spring 36 can pull the chute block 20 and the translation block 18 to approach each other. A synchronizing member for keeping the structure moving synchronously is connected between the translation block 18 and the translation track 6.

[0023] Specifically, as Figure 1 and Figure 4 shown, a second slide bar 17 is connected to one side of the workbench 1. The translation block 18 is slidably connected to the second slide bar 17. By setting the second slide bar 17, the stability of the horizontal sliding of the translation block 18 is improved. There are two second slide bars 17.

[0024] Specifically, as Figure 4 shown, a limiting rod 19 is connected to the outside of the chute block 20. The translation block 18 is slidably connected to the limiting rod 19. The docking spring 36 is sleeved on the limiting rod 19. By setting the limiting rod 19, the position between the translation block 18 and the chute block 20 is limited. The two structures can only approach or move away from each other horizontally.

[0025] Specifically, asFigure 2 and Figure 4 As shown in Figure 4 , the synchronizing member includes a traction bar 21. A first chute 3 and a third chute 24 are formed on the working table 1. One side of the translation track 6 is connected with a first sliding rod 22, and one side of the translation block 18 is connected with a third sliding rod 23. The first sliding rod 22 and the third sliding rod 23 are respectively slidably connected to the first chute 3 and the third chute 24. Both ends of the traction bar 21 are respectively connected to the first sliding rod 22 and the third sliding rod 23. By providing the traction bar 21, the movement of the translation block 18 is synchronized with the movement of the translation track 6, and the structures of the first chute 3 and the third chute 24 ensure the stability of the synchronous horizontal movement.

[0026] Specifically, as Figure 2 shown in Figure 2 , a cylinder shaft 28 is connected to the working table 1, and the main cylinder 27 is rotatably connected to the cylinder shaft 28. During the deflection process of the main cylinder 27, the main cylinder 27 must be in a telescopic operating state.

[0027] In summary, for a fast food box production and palletizing device provided in this embodiment, when fast food boxes need to be produced and palletized, the processed fast food boxes will move to the lower part of the suction cup 8 along with the conveyor belt 2. The suction cup 8 needs to be externally connected to an air pump structure. When the suction cup 8 needs to transfer the fast food boxes, the suction cup 8 sucks air, thereby completing the adsorption and transfer of the fast food boxes. When the suction cup 8 moves to the placing table 10, the suction cup 8 stops sucking air, thereby stably placing the fast food boxes on the placing table 10.

[0028] The operator only needs to start the main cylinder 27 to drive the fourth sliding rod 26 connected to the telescopic end of the main cylinder 27 to slide on the fourth chute 25. The fourth chute 25 is composed of a section of "V"-shaped and a section of horizontal track. The initial state of the main cylinder 27 is an extended state. After the main cylinder 27 is started, it will contract, thereby driving the fourth sliding rod 26 to start horizontal movement. After the movement is completed, it will start to rise and then fall along the "V"-shaped track.

[0029] When the fourth sliding rod 26 moves horizontally, at this time, the fourth sliding rod 26 pulls the chute block 20 to move horizontally. Since a docking spring 36 is connected between the chute block 20 and the translation block 18, the chute block 20 can move horizontally synchronously with the translation block 18. The third sliding rod 23 connected to the outside of the translation block 18 is used in cooperation with the traction bar 21 to drive the translation track 6 to move horizontally.

[0030] When the translation track 6 moves horizontally, since one side of the lifting bar 7 slidably connected to the translation track 6 is connected to the second sliding rod 30, and the second sliding rod 30 is limited by the second chute 5, where the second chute 5 is composed of a track with both ends sloping downward and the middle horizontal. When the second sliding rod 30 slides to both ends of the second chute 5, the suction cup 8 connected to the lower end of the lifting bar 7 will move downward. The downward-sloping structures at both ends of the second chute 5 respectively correspond to the actions of the suction cup 8 adsorbing the fast food box on the conveyor belt 2 and the suction cup 8 driving the fast food box downward and placing it on the placing table 10. Therefore, the operating state of the air pump connected to the suction cup 8 can be adjusted by the moving position of the second sliding rod 30 on the second chute 5. When the second sliding rod 30 is located at one end of the second chute 5 far from the placing table 10, the air pump starts, and when the second sliding rod 30 is located at one end of the second chute 5 close to the placing table 10, the air pump stops running.

[0031] When the horizontal movement of the fourth sliding rod 26 is completed and it starts to move on the "V"-shaped track, at this time, the translation block 18 slides to one end of the second slide bar 17. A limiting structure is provided at one end of the second slide bar 17 close to the stacking cylinder 9 to limit the sliding separation between the translation block 18 and the second slide bar 17. At this time, when the main cylinder 27 continues to contract, the translation block 18 stops moving due to the limiting structure at one end of the second slide bar 17, but the chute block 20 will continue to move towards the stacking cylinder 9. At this time, the docking spring 36 starts to be stretched, and the fourth sliding rod 26 also starts to slide on the chute block 20. When the fourth sliding rod 26 slides along the fourth chute 25, it will first rise in height. At this time, the fourth sliding rod 26 moves above the deflecting rod 14, and then the height of the fourth sliding rod 26 drops. The fourth sliding rod 26 is used to press down the deflecting rod 14, causing the deflecting rod 14 to deflect. When the deflecting rod 14 deflects downward, it does not drive the gear 13 to rotate. At this time, the pawl 32 deflects, and the torsion spring 34 structure starts to store energy, and the return spring 16 structure is compressed.

[0032] When the main cylinder 27 contracts to the maximum extent, at this time, the deflecting rod 14 deflects downward to the maximum angle. Then the main cylinder 27 starts to extend, and the fourth sliding rod 26 cancels the pressing on the deflecting rod 14. At this time, the deflecting rod 14 is pushed upward by the L-shaped frame 35 and deflects upward. Using the jamming between the pawl 32 and the ratchet 31, the gear 13 is driven to rotate. The deflecting shaft 29 connected to the gear 13 is in a tightly connected state with the operating table 1. Without external force, the deflecting shaft 29 does not rotate. The toothed block 12 and the placing table 10 are of light texture, so the gravity of the toothed block 12 and the placing table 10 cannot drive the gear 13 to rotate either. Subsequently, when stacking the fast food boxes, since the fast food boxes are light in weight, placing them on the placing table 10 will not drive the deflecting shaft 29 to rotate. As the main cylinder 27 extends, the suction cup 8 structure will reset to the initial position.

[0033] In summary, when the main cylinder 27 contracts and extends to the maximum state, the fast food box can be moved to the placement table 10. Subsequently, the placement table 10 descends by a fixed height, and so on. When the main cylinder 27 reciprocates telescopically, the fast food boxes can be stably palletized on the placement table 10. The height of the placement table 10 will gradually decrease as the palletizing progresses, ensuring that the fast food boxes can be stably stored in the palletizing cylinder 9. When it is necessary to collect the palletized fast food boxes uniformly, only the offset shaft 29 needs to be pulled out to cancel the limit of the gear 13 on the tooth block 12. Since the upper end of the L-shaped frame 35 is a crossbar structure, when the offset shaft 29 is pulled out, the deflection rod 14 still abuts against the L-shaped frame 35. The operator holds the handle 11 and pushes the placement table 10 upward to complete the palletizing and collection of the fast food boxes in the palletizing cylinder 9, and then the offset shaft 29 can be reset.

[0034] Through this device, the automatic palletizing operation of fast food boxes is realized. During the palletizing process, no manual operation is required, avoiding the problem of manual contamination of fast food boxes, greatly improving the palletizing quality and efficiency. Compared with large-scale equipment, it has the characteristics of low cost and good stability, and the palletizing operation can be carried out orderly and stably.

[0035] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
