Description

Technical Field

[0001] The present invention relates to the technical field of fast food box production, in particular to a fast food box production and stacking device. Background Art

[0002] Fast food boxes are disposable containers used to hold fast food. They are highly adaptable to modern fast-paced life. They are convenient and easy to carry, allowing consumers to eat anytime and anywhere. They are disposable, effectively reducing cross-contamination and ensuring hygiene and safety. At the same time, they are low-cost and suitable for large-scale production to meet the needs of the catering industry.

[0003] During the production of fast food boxes, in order to facilitate the collection and processing of fast food boxes, they are usually palletized after production is completed. Since fast food boxes are light in texture and have poor structural stability during palletizing, the traditional placement method requires complete exclusion of the air between the upper and lower layers. Palletizing by free fall will affect the palletizing quality because the air between the fast food boxes is not pressed out. Manual palletizing will also cause uneven pressure during palletizing, resulting in uneven gaps between the fast food boxes after palletizing, resulting in space waste or fast food boxes being damaged by being pressed. Manual operation also increases the probability of fast food boxes being contaminated. Therefore, there is a lack of effective palletizing equipment for this type of product.

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

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 5 , the present invention provides a technical solution:

[0029] A fast food box production and stacking device includes a workbench 1, a conveyor belt 2 is connected to the workbench 1, and the fast food box can be transported along with the conveyor belt 2. When the fast food box is moved to one end of the conveyor belt 2, its structure will be blocked by the protective edge at one end of the conveyor belt 2 and stop moving. At this time, the fast food box waits for the suction cup 8 to transfer and transport for stacking. A translation track 6 is slidably connected to one side of the workbench 1, and 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 connected to the air pump through an air pipe, and the operating state of the air pump is the same as that of the air pump. The position of the suction cup 8 is related. When the suction cup 8 is located above the conveyor belt 2, the air pump starts to suck air. When the suction cup 8 moves to the placement table 10, the air pump stops running, and the fast food box adsorbed on the suction cup 8 can be placed on the placement table 10. A chute 2 5 is provided on the workbench 1, and a slide bar 2 30 is connected to one side of the lifting bar 7. The slide bar 2 30 is slidably connected to the chute 2 5. The chute 2 5 is a track with both ends obliquely downward and a horizontal structure in the middle. The oblique downward arrangement at both ends is convenient for the suction cup 8 to adsorb the fast food box and the suction cup 8 to place the fast food box on the placement table 10;

[0030] One side of the workbench 1 is connected to a stacking tube 9, and a placement platform 10 is slidably connected to the stacking tube 9. A handle 11 is connected to the outside of the placement platform 10. The handle 11 structure is slidably connected to the stacking tube 9. A gear block 12 is connected to one side of the placement platform 10. A deflection shaft 29 is rotatably connected to the workbench 1. The deflection shaft 29 and the workbench 1 are rotatably connected. The structures at the connection are tightly abutted against each other. Without the action of external force, the deflection shaft 29 is not easy to rotate. When the gear 13 is acted upon by the placement platform 10 and the gear block 12, the deflection shaft 29 still does not rotate. A ratchet 31 and a gear 13 are connected. The ratchet 31 structure enables the deflection shaft 29 to rotate in only one direction. The deflection shaft 29 is rotatably connected to a deflection rod 14. The deflection rod 14 is connected to a connecting rod 33. The connecting rod 33 is connected to a pawl 32 and a torsion spring 34. The torsion spring 34 structure ensures that the pawl 32 is always deflected toward 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 is provided below the deflection rod 14 to push the deflection rod 14 to reset the deflection.

[0031] The workbench 1 is connected to a transmission mechanism that first drives the suction cup 8 to transfer the fast food box to the placement table 10, and then drives the placement table 10 to lower its height. After the fast food box is driven by the suction cup 8 and placed on the placement table 10, the placement table 10 is lowered, and then the suction cup 8 transfers the fast food box again and presses it on the previous fast food box, that is, the fast food boxes are alternately transferred and stacked. When the equipment is installed, the placement table 10 can be debugged so that the height it descends each time is the same as the thickness of the fast food box, thereby improving the stacking quality of the fast food boxes and ensuring that the fast food boxes can be evenly docked and stacked together.

[0032] Specifically, such as Figure 1 As shown, a slide bar 4 is connected to the outside of the workbench 1, and a translation track 6 is slidably connected to the slide bar 4. The stability of the horizontal movement of the translation track 6 is ensured by setting the slide bar 4. A slide bar 22 is also set on one side of the translation track 6 to further improve the stability of the structural translation.

[0033] Specifically, such as Figure 1 As 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 reset spring 16, and a limiting cylinder 15 is provided on the outer side of the reset spring 16 and the L-shaped frame 35. The reset spring 16 can push the deflection rod 14 to reset after deflection when it is not affected by external force. The long rod structure at the upper end of the L-shaped frame 35 is to facilitate the abutment state between the deflection rod 14 and the L-shaped frame 35 when the deflection shaft 29 is pulled out, and it is also convenient for the subsequent reset of the deflection shaft 29 structure.

[0034] Specifically, such as Figure 1 、 Figure 2 and Figure 4 As shown, the transmission mechanism includes a sliding rod four 26, a sliding groove four 25 is opened on the workbench 1, and a main cylinder 27 is rotatably connected to the sliding rod four 26. The main cylinder 27 is rotatably connected to the workbench 1. After starting, the main cylinder 27 will be in a reciprocating extension and contraction state until the fast food boxes stacked in the stacking tube 9 reach the upper limit. At this time, it is necessary to manually stop the main cylinder 27, and then collect the stacked fast food boxes. The main cylinder 27 can complete the stacking of a fast food box by one reciprocating extension and contraction. Therefore, the main cylinder 27 can also be set to automatically stop operation after a certain number of reciprocating extensions and contractions. A translation block 18 is slidably connected to one side of the workbench 1, and a slide block 20 is slidably connected to one side of the translation block 18. The sliding rod four 26 is slidably connected to the slide block 20. A docking spring 36 is connected between the slide block 20 and the translation block 18. The docking spring 36 can pull the slide block 20 and the translation block 18 closer to each other. A synchronization member for keeping the structure moving synchronously is connected between the translation block 18 and the translation rail 6.

[0035] Specifically, such as Figure 1 and Figure 4 As shown, a second slide bar 17 is connected to one side of the workbench 1, and 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, wherein two second slide bars 17 are provided.

[0036] Specifically, such as Figure 4As shown, a limiting rod 19 is connected to the outside of the slide block 20, the translation block 18 is slidably connected to the limiting rod 19, and 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 slide block 20 is limited, and the two structures can only approach or move away from each other in the horizontal direction.

[0037] Specifically, such as Figure 2 and Figure 4 As shown, the synchronization parts include a traction bar 21, a slide groove 3 and a slide groove 3 24 are opened on the workbench 1, a slide bar 22 is connected to one side of the translation track 6, and a slide bar 3 23 is connected to one side of the translation block 18. The slide bar 1 22 and the slide bar 3 23 are respectively slidably connected to the slide groove 1 3 and the slide groove 3 24, and the two ends of the traction bar 21 are respectively connected to the slide bar 1 22 and the slide bar 3 23. By setting the traction bar 21, the movement of the translation block 18 and the movement of the translation track 6 are kept synchronized, and the structure of the slide groove 1 3 and the slide groove 3 24 ensures the stability of the synchronous horizontal movement.

[0038] Specifically, such as Figure 2 As shown, a cylinder shaft 28 is connected to the workbench 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 operation state.

[0039] To sum up, the present embodiment provides a fast food box production and stacking device. When fast food boxes need to be produced and stacked, the processed fast food boxes will move with the conveyor belt 2 to the bottom of the suction cup 8, wherein the suction cup 8 needs to be connected to an external air pump structure. When the suction cup 8 needs to transfer the fast food box, the suction cup 8 inhales air, thereby completing the adsorption and transfer of the fast food box. When the suction cup 8 moves to the placement table 10, the suction cup 8 stops inhaling air, thereby stably placing the fast food box on the placement table 10.

[0040] The operator only needs to start the main cylinder 27 to drive the sliding rod four 26 connected to the telescopic end of the main cylinder 27 to slide on the slide groove four 25, where the slide groove four 25 is composed of a "V" shape and a horizontal track. The initial state of the main cylinder 27 is the extended state. After the main cylinder 27 is started, it will contract, thereby driving the sliding rod four 26 to start horizontal movement. After the movement is completed, it will start to rise and then fall along the "V"-shaped track.

[0041] When the slide bar four 26 moves horizontally, the slide bar four 26 pulls the slide block 20 to move horizontally. Since a docking spring 36 is connected between the slide block 20 and the translation block 18, the slide block 20 can keep synchronized with the translation block 18 in horizontal movement, and the slide bar three 23 connected to the outside of the translation block 18 cooperates with the traction bar 21 to drive the translation track 6 to move horizontally.

[0042] When the lifting bar 7 is tilted downwards, the lifting bar 7 is tilted downwards, and the lifting bar 7 is tilted downwards, so that ...

[0043] When the horizontal movement of the slide bar 4 26 is completed and it begins to move on the "V"-shaped track, the translation block 18 slides to one end of the slide bar 2 17, wherein the slide bar 2 17 is provided with a limit structure near one end of the stacking tube 9 to limit the sliding separation between the translation block 18 and the slide bar 2 17. At this time, when the main cylinder 27 continues to contract, the translation block 18 is stopped by the limit structure at one end of the slide bar 2 17, but the chute block 20 will continue to move toward the side of the stacking tube 9, and the docking spring 36 begins to be pulled. The slide bar 26 extends, and the slide bar 26 also starts to slide on the slide block 20. When the slide bar 26 slides along the slide bar 25, it will first rise in height. At this time, the slide bar 26 moves above the deflection rod 14, and then the slide bar 26 drops in height. The slide bar 26 is used to press the deflection rod 14, so that the deflection rod 14 is deflected. When the deflection rod 14 deflects downward, it does not drive the gear 13 to rotate. At this time, the pawl 32 is deflected, the torsion spring 34 structure begins to accumulate force, and the return spring 16 structure is compressed.

[0044] When the main cylinder 27 contracts to its maximum extent, the deflection rod 14 deflects downward to its maximum angle, and then the main cylinder 27 begins to extend, and the slide rod 26 cancels the pressure on the deflection rod 14. At this time, the deflection rod 14 is pushed upward by the L-shaped frame 35, and the pawl 32 and the ratchet 31 are locked, thereby driving the gear 13 to rotate. The deflection shaft 29 connected to the gear 13 is tightly connected to the workbench 1. In the absence of external force, the deflection shaft 29 does not rotate. The gear block 12 and the placement table 10 are light in texture, so the gravity of the gear block 12 and the placement table 10 cannot drive the gear 13 to rotate. Later, when stacking the fast food boxes, due to the light weight of the fast food boxes, placing them on the placement table 10 will not drive the deflection shaft 29 to rotate. As the main cylinder 27 extends, the suction cup 8 structure will reset to its initial position.

[0045] To sum up, when the main cylinder 27 contracts and extends to its maximum state, the fast food box can be moved to the placement table 10, and then the placement table 10 is lowered to a fixed height, and so on. When the main cylinder 27 reciprocates and contracts, the fast food box can be stably stacked on the placement table 10. The height of the placement table 10 will gradually decrease as the stacking progresses, ensuring that the fast food box can be stably stored in the stacking tube 9. When the stacked fast food boxes need to be collected together, it is only necessary to pull out the deflection shaft 29 and cancel the limit of the gear 13 on the tooth block 12. Since the upper end of the L-shaped frame 35 is a cross bar structure, when the deflection shaft 29 is pulled out, the deflection rod 14 is still in a mutual abutment state with the L-shaped frame 35. The operator holds the handle 11 and pushes the placement table 10 upward to complete the stacking and collection of the fast food boxes in the stacking tube 9, and then resets the deflection shaft 29.

[0046] This device realizes the automated palletizing of fast food boxes. No manual operation is required during the palletizing process, which avoids the problem of manual contamination of fast food boxes and greatly improves 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 in an orderly and stable manner.
