Description

Technical Field

[0001] The invention relates to the field of lunch box production, and more specifically to a fast food box production and stacking device. Background Art

[0002] With the accelerated pace of life in modern society, fast food has become a way of life. Therefore, the market demand for fast food is gradually increasing. During the production process, fast food boxes need to go through a series of processes such as heating, forming, punching and shearing. After the fast food boxes are produced, they need to be stacked neatly using a stacking device, and then the entire stack of fast food boxes is taken away manually.

[0003] The existing palletizing device is not convenient to compress the fast food boxes during palletizing. Since the fast food boxes are light in texture, they are relatively fluffy when stacked together, making it difficult to clamp them one by one, and they are easy to fall during subsequent transportation.

[0004] In order to solve the above technical problems, a Chinese patent with the authorization announcement number CN218114303U discloses a fast food box production stacking device, which starts the rotating driving member to drive the cross arm to rotate to the top of the stacking box, and the third telescopic driving member drives the pressure plate to move downward, so that it applies a certain pressure to the fast food boxes inside the stacking box, and compresses the stacked fast food boxes, so that each layer of fast food boxes is clamped one by one, thereby preventing the fast food boxes from falling during subsequent transportation;

[0005] The existing lunch boxes are mainly transferred by suction by suction cups. Since there are grooves of different sizes on the lunch boxes, the area on the back that can be sucked is relatively fixed, and the existing suction cups are fixedly installed, so they can only suck on lunch boxes of the same specification. Lunch boxes of different specifications have different positions of grooves, which makes the suction cups unable to be well sucked on the lunch boxes, and have high limitations.

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0046] Please refer to Figures 1 to 11 , a fast food box production and palletizing device, including side plates 1. A module slide rail 9 is fixedly connected to the top of the side plates 1. A moving arm 8 is slidably connected to the front side of the module slide rail 9. A hydraulic push rod 7 is fixedly connected to the upper surface of the moving arm 8. A bottom plate 2 is fixedly connected to the front side of the side plates 1. A rotating motor 3 is fixedly connected to the upper surface of the bottom plate 2. An output end of the rotating motor 3 is fixedly connected to a top plate 4. An adsorption assembly 5 for transporting meal boxes is fixedly connected to an output end of the hydraulic push rod 7. Limiting assemblies 6 are connected to both sides of the top plate 4.

[0047] As Figure 2 - Figure 4 shown, the adsorption assembly 5 includes a U-shaped connecting plate 51 fixed to the output end of the hydraulic push rod 7. A cross plate 52 is fixedly connected to the bottom of the U-shaped connecting plate 51. Fixed columns 513 are fixedly connected to four corners of the lower surface of the cross plate 52. A gear 514 is fixedly connected to the outer surface of the fixed column 513. A slide rail 53 is rotatably connected to the lower surface of the fixed column 513. An internally threaded slider 57 is slidably connected to the inside of the slide rail 53. An electric suction cup 56 is fixedly connected to the bottom of the internally threaded slider 57. First threaded rods 58 are rotatably connected to both sides of the inner surface of the slide rail 53. A first fixing plate 59 is fixedly connected to one side of the upper surface of the slide rail 53. A pull rod 510 is slidably connected to the inside of the first fixing plate 59. A rack 512 is fixedly connected to one side of the pull rod 510. A second spring 511 is sleeved on the outer surface of the pull rod 510. A first dust removal assembly 54 is arranged at the inner top of the U-shaped connecting plate 51. Second dust removal assemblies 55 are arranged on both sides of the U-shaped connecting plate 51.

[0048] One side of the first threaded rod 58 extends out of the inside of the slide rail 53 and is fixedly connected to an anti-slip rotating handle. The first threaded rod 58 penetrates through the inside of the internally threaded slider 57 and is threadedly connected. The rack 512 and the gear 514 are meshed with each other. The second spring 511 is located between the first fixing plate 59 and the rack 512.

[0049] Before palletizing the lunch boxes, it is necessary to effectively adjust the position of the electric suction cup 56 according to the actual size and specifications of the lunch boxes. At this time, pull the pull rod 510 to drive the rack 512 to move, so that the rack 512 is separated from the gear 514, releasing the fixing effect on the slide rail 53. Rotate the slide rail 53 around the fixed column 513 to drive the electric suction cup 56 to perform a circular motion for position adjustment. At the same time, when adjusting, rotate the first threaded rod 58 to drive the internally threaded slider 57 to move inside the slide rail 53. The internally threaded slider 57 drives the electric suction cup 56 to perform a linear movement, so that the electric suction cup 56 can move to various positions, adapt to lunch boxes of different specifications, and each electric suction cup 56 can adjust itself without interfering with other electric suction cups 56. In actual production, it is possible to avoid replacing different equipment for palletizing operations and reduce the necessity of purchasing different equipment.

[0050] As Figure 5 and Figure 6 shown, the first dust removal component 54 includes an air pump 547 fixed to the inner top of the U-shaped connecting plate 51 and a double-shaft motor 541 fixed to the upper surface of the cross plate 52. The output end of the double-shaft motor 541 is fixedly connected with a worm 542. The output end of the air pump 547 is fixedly connected with a four-way pipe 548. The left and right ends of the four-way pipe 548 are fixedly connected with fixed pipes 549. Both ends of the fixed pipe 549 are connected with rotary joints 544. The outer surface of a rotary joint 544 located on different fixed pipes 549 is fixedly connected with a worm gear 543. One side of the two rotary joints 544 away from each other is fixedly connected with a connecting pipe 545. One end of the two connecting pipes 545 is fixedly connected with a flow guide plate 546. The upper surface of the flow guide plate 546 is evenly provided with air outlets 5410.

[0051] One end of the four-way pipe 548 penetrates through the inside of the U-shaped connecting plate 51. The worm 542 meshes with the worm gear 543. The flow guide plate 546 is located directly below the slide rail 53. The flow guide plate 546, the connecting pipe 545, and the fixed pipe 549 are interconnected.

[0052] During palletizing, the meal boxes are mainly transferred by the electric suction cup 56. Due to the long-term operation of the electric suction cup 56, some dust will adhere to the surface of the electric suction cup 56. The dust will affect the adsorption effect of the electric suction cup 56, and even cause the meal boxes to fall during the transfer, which requires manual handling and collection. Therefore, before each palletizing, the air pump 547 is turned on to work. The air pump 547 delivers air flow into the inside of the four-way pipe 548. The air flow enters the inside of the deflector 546 through the inside of the fixed pipe 549 and the connecting pipe 545. The deflector 546 then sprays out through a plurality of air outlets 5410. Then the double-shaft motor 541 is turned on to drive the two worm gears 542 to rotate. The worm gears 542 drive the rotary joint 544 and the connecting pipe 545 to rotate through the worm wheels 543, and the deflector 546 located on the cross plate 52 is rotated 180 degrees, so that the air outlets 5410 on the deflector 546 face the bottom of the electric suction cup 56. The air flow sprayed out from the air outlets 5410 blows towards the bottom of the electric suction cup 56, which can blow off the dust attached to the bottom of the electric suction cup 56, keep the electric suction cup 56 clean again, avoid the influence of dust on the adsorption force of the electric suction cup 56, and improve the stability of the electric suction cup 56 in adsorbing the meal boxes. After the surface of the electric suction cup 56 is cleaned, the double-shaft motor 541 drives the worm gear 542 to reverse, and drives the deflector 546 to flip and reset through transmission, so as to avoid hindering the operation of the electric suction cup 56.

[0053] As Figure 3 and Figure 6 shown, the second dust removal assembly 55 includes support plates 551 fixed on both sides of the U-shaped connecting plate 51 and a circular air jet frame 555 fixed at the bottom end of the four-way pipe 548. Two telescopic rods 553 are slidably connected inside the support plates 551. A first spring 554 is sleeved on the outer surfaces of the two telescopic rods 553. The tops of the two telescopic rods 553 are fixedly connected with a rubber sheet sealing strip 552, and one side of the rubber sheet sealing strip 552 is provided with an inclined surface.

[0054] Although the dust on the surface of the electric suction cup 56 can be effectively removed, the dust on the lunch box cannot be effectively removed, and the dust on the lunch box will still affect the adsorption force of the electric suction cup 56. Therefore, while the electric suction cup 56 adsorbs the lunch box, the air pump 547 is always in an open state, and the guide plate 546 moves to the top of the rubber sheet sealing strip 552 when rotating and resetting, and the guide plate 546 contacts the inclined surface of the rubber sheet sealing strip 552 and presses the rubber sheet sealing strip 552 downward. When the guide plate 546 is completely reset, the rubber sheet sealing strip 552 is squeezed by the first spring 554 and tightly contacts the guide plate 546 to close the air outlet 5410. At this time, the airflow of the air pump 547 all enters the circular jet frame 555, and then is blown to the surface of the lunch box by the circular jet frame 555, so that the dust on the surface of the lunch box can be effectively removed, which can not only ensure the adsorption force of the electric suction cup 56, but also ensure the cleanliness of the lunch box, and avoid dust gathering on the lunch box to pollute it.

[0055] like Figure 7 - Figure 8 As shown, the limit assembly 6 includes a mounting plate 61 fixed on one side of the top plate 4, a support plate groove 610 is opened on the upper surface of the mounting plate 61, second fixing plates 62 are fixedly connected to both sides of the upper surface of the mounting plate 61, the two second fixing plates 62 are internally threadedly connected to second threaded rods 63, the two second threaded rods 63 are rotatably connected to a C-shaped rod 64 on one side close to each other, the two C-shaped rods 64 are fixedly connected to two limit sleeves 67 on one side close to each other, the two limit sleeves 67 are internally slidably connected to a limit extension plate 68, a support plate 69 is arranged inside the support plate groove 610, lifting assemblies 65 are arranged on both sides of the inner surface of the support plate groove 610, and a roller assembly 66 is arranged at the bottom of the support plate groove 610.

[0056] One side of the limit extension plate 68 is threadedly connected with a locking screw, one side of the locking screw contacts one side of the limit extension plate 68, the second threaded rod 63 is connected to the C-shaped rod 64 through a bearing, and two receiving grooves are provided inside the support plate 69.

[0057] When the lunch boxes are stacked, when the lunch boxes are stacked to a certain height, the lunch box stack will easily fall over and need to be limited. The prior art limits the lunch box stack by setting limit rods on both sides, but different lunch box stacks require different stacking heights, and the limit rods that are too high cannot limit the excess part. Therefore, at the beginning of stacking, the limit extension plate 68 inside the limit sleeve 67 is pulled to move the limit extension plate 68 to the required height, and the limit extension plate 68 is squeezed by turning the locking screw to effectively fix the limit extension plate 68, and the two second threaded rods 63 are rotated to drive the C-shaped rod 64 and the limit sleeve 67 to move closer to the support plate 69, and the limit sleeve 67 is moved to a suitable position according to the actual size of the lunch boxes. During subsequent stacking, the cooperation of the four limit extension plates 68 can limit the lunch box stacks of different heights to prevent the overly high lunch box stacks from falling over.

[0058] like Figure 8 , Fig. 9 and Fig.11 As shown, the lifting assembly 65 includes a C-shaped groove 651 opened on one side of the inner surface of the support plate groove 610, a first servo motor 654 fixed on both sides of the lower surface of the mounting plate 61, and two telescopic sleeves 658 inside the support plate 69, the top of the telescopic sleeve 658 is fixedly connected with a lifting plate 659, the output end of the first servo motor 654 is provided with a third threaded rod 653, the top of the third threaded rod 653 extends to the inside of the C-shaped groove 651, the outer surface of the third threaded rod 653 is threadedly connected with a C-shaped plate 652, the front and rear sides of the upper surface of the C-shaped plate 652 are provided with sliding grooves 657, the front and rear sides of one side of the C-shaped plate 652 are slidably connected with an extension plate 655, and the upper surface of the extension plate 655 is fixedly connected with a push rod 656.

[0059] The lifting plate 659 is located inside the storage groove of the support plate 69 and is adapted to each other. The top of the push rod 656 passes through the slide groove 657, and the push rod 656 and the slide groove 657 slide with each other. The top of the extension plate 655 is lower than the bottom of the lifting plate 659, and the width of the extension plate 655 is consistent with that of the lifting plate 659.

[0060] When palletizing existing lunch boxes, they are generally directly stacked on the pallet. However, in the subsequent transportation, the lunch box stack needs to be bundled and packed. However, the lunch box stack is in close contact with the pallet. When bundling, it is necessary to pass under the lunch box stack. This operation can easily cause the lunch box stack to fall over. Therefore, after the lunch box stacking is completed, the rotating motor 3 drives the top plate 4 to rotate 180 degrees to transfer the lunch box stack out of the working area. Another support plate 69 continues to stack, and the push rod 656 drives the extension plate 655 to move below the lifting plate 659. When all four extension plates 655 are moved to the bottom of the lifting plate 659, the first servo motor 654 is turned on to drive the third threaded rod 653 to rotate, and the first servo motor 654 drives the C-shaped plate 652 to move upward, and at the same time drives the four extension plates 655 to push the lifting plate 659 to move upward. The lifting plate 659 pushes the stack of lunch boxes above the support plate 69 to move upward, so that a certain gap is generated between the stack of lunch boxes and the support plate 69. At this time, it is more convenient to bundle the stack of lunch boxes, and it is easy for the rope to pass between the stack of lunch boxes and the support plate 69 to prevent the stack of lunch boxes from tipping over during bundling.

[0061] like Figure 8 and Fig.11 As shown, the roller assembly 66 includes two second servo motors 661 fixed between two second fixed plates 62 on the upper surface of the mounting plate 61, the output end of the second servo motor 661 is fixedly connected with a fourth threaded rod 662, the fourth threaded rod 662 passes through the interior of the mounting plate 61, the outer surface of the fourth threaded rod 662 is threadedly connected with an internal threaded sleeve 663, the side of the two internal threaded sleeves 663 close to each other is fixedly connected with a pulley base plate 664, the upper surface of the pulley base plate 664 is evenly rotatably connected with five pulleys 665, the pulleys 665 correspond one-to-one to the pulley grooves 666 and are located inside the pulley grooves 666.

[0062] When the stack of lunch boxes is bundled, the second threaded rod 63 is rotated to drive the two C-shaped rods 64 to move away from each other. At this time, the packaging bag can be put on the stack of lunch boxes. At this time, the pallet 69 needs to be moved out from the inside of the pallet groove 610. At this time, the second servo motor 661 is turned on to drive the fourth threaded rod 662 to rotate, and the pulley bottom plate 664 is driven to move upward through the internal threaded sleeve 663. The pulley bottom plate 664 drives the pulley 665 to enter the inside of the pulley groove 666, gradually contacting the bottom of the pallet 69 and lifting the pallet 69 upward. At this time, the pallet 69 is fully supported on the pulley 665, and the pallet 69 can be pushed out from the inside of the pallet groove 610, which is more labor-saving and convenient.

[0063] Method of use: First, the slide rail 53 is rotated around the fixed column 513 to drive the electric suction cup 56 to move in a circular motion to exchange positions. At the same time, when exchanging, the first threaded rod 58 is rotated to drive the internal threaded slider 57 to move inside the slide rail 53, and the internal threaded slider 57 drives the electric suction cup 56 to move linearly, so that the electric suction cup 56 can move to various positions, and the guide plate 546 located on the horizontal plate 52 is rotated 180 degrees, so that the air outlet 5410 on the guide plate 546 faces the bottom of the electric suction cup 56, and the airflow ejected from the air outlet 5410 blows toward the bottom of the electric suction cup 56, which can blow off the dust attached to the bottom of the electric suction cup 56, and the rubber sheet sealing strip 552 contacts the guide plate 546 to close the air outlet 5410. At this time, the airflow of the air pump 547 all enters the circular jet frame 555, and then blows toward the surface of the lunch box by the circular jet frame 555, which can effectively remove the dust on the surface of the lunch box.

[0064] The height of the limit extension plate 68 can be adjusted at will to limit the stacks of lunch boxes at different heights. At the same time, with the cooperation of the various parts of the lifting assembly 65, the lifting plate 659 can be lifted so that there is a certain gap between the stack of lunch boxes and the support plate 69, which is convenient for bundling the stack of lunch boxes. At the same time, the various parts of the roller assembly 66 cooperate to move the pulley 665 to the inside of the pulley groove 666 and lift the support plate 69, so that the support plate 69 can be quickly removed from the inside of the support plate groove 610.
