Description

Technical Field

[0001] The present invention relates to the technical field of stacking equipment, and in particular to stacking equipment for carton production. Background Art

[0002] As an indispensable part of modern logistics, packaging cartons bear the important responsibility of packaging, protecting products and aesthetics. They are usually used as wrapping materials for goods or as outer protective materials for goods. The volume of cartons varies according to the size of goods. Cartons usually have various patterns or text prompts such as "handle with care", "afraid of moisture", "upward", "stack limit" and "afraid of sunlight" to remind users to pay attention to protect the contents from damage. During the production process of cartons, the produced cartons need to be stacked neatly for storage or transportation. At present, when stacking cartons, plywood is generally used to clamp the cartons or vacuum adsorption is used to suck the cartons from the top of the cartons.

[0003] A Chinese patent application document with publication number CN117342277A discloses a palletizing gripper for carton production. The palletizing gripper has a first grabbing plate and a second grabbing plate that occupy a small area when placing cartons, and does not affect the neat stacking of cartons. The first grabbing plate can be moved out from the gap between the cartons, and has strong gripping stability. Only the second electric push rod is used to consume power, which is beneficial to energy use.

[0004] However, the structural design of the above-mentioned related technology is as follows: in the process of stacking cartons, it is necessary to leave a gap between the cartons to allow the clamping plates for clamping the cartons to move out. However, as the stacking height of the cartons increases, the impact caused by the gap between the cartons becomes greater, and the risk of tipping over is more likely to occur. If an external device is used to push the entire layer of stacked cartons to align, it is necessary to squeeze the stacked cartons, and in the process of pushing the cartons, greater friction will be generated between the cartons, which will easily cause scratches on the cartons, thereby affecting the appearance of the cartons.

[0005] Therefore, a stacking device for carton production is proposed to solve the above-mentioned problems. Summary of the invention

[0034] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] like Figures 1 to 4 As shown, the stacking equipment for carton production of the present invention comprises a mechanical arm 11, a clamping mechanism, a conveying mechanism, a positioning mechanism and a box pressing mechanism. The clamping mechanism is installed on the mechanical arm 11 to clamp the carton, the conveying mechanism is arranged inside the clamping mechanism to eliminate the gap between the carton, the positioning mechanism is arranged on the top side of the clamping mechanism to press the carton in front of the clamping mechanism, and the box pressing mechanism is slidably arranged on the clamping mechanism to press the carton on the side of the clamping mechanism. After the clamping mechanism clamps the carton, the mechanical arm 11 drives the carton to move to the pallet through the clamping mechanism, at which time the clamping mechanism cancels the clamping of the carton and conveys the carton to the pallet through the conveying mechanism.

[0036] like Figures 1 to 3As shown, the clamping mechanism includes an electric slide rail 21, a mounting plate 22, a mounting seat 23, a lower clamping plate 24, a connecting seat 25 and an upper clamping plate 26. There are two electric slide rails 21, the mounting plate 22 is installed between the two electric slide rails 21, the mounting plate 22 is fixed to the robot arm 11, the mounting seat 23 is installed at the bottom of one side of the electric slide rail 21, the lower clamping plate 24 is installed at one side of the mounting seat 23, the conveying mechanism is arranged on the top of the lower clamping plate 24, the connecting seat 25 is slidably connected to the top of one side of the electric slide rail 21, the upper clamping plate 26 is installed at one side of the connecting seat 25, the positioning mechanism is arranged on one side of the top of the upper clamping plate 26, and the box pressing mechanism is slidably arranged on the connecting seat 25.

[0037] When clamping the carton, the carton is transported to the top of the conveying mechanism through an external conveying device. At this time, the electric slide rail 21 drives the upper clamping plate 26 to move downward through the connecting seat 25 and clamp the carton.

[0038] Continue to refer Figures 1 to 3 As shown, the conveying mechanism includes a conveying assembly 1 31, a conveying assembly 2 32, a driving assembly 33 and a transmission assembly 34. The conveying assembly 1 31 is arranged on the top of the lower clamping plate 24, the conveying assembly 2 32 is arranged inside the conveying assembly 1 31, the conveying speeds of the conveying assembly 1 31 and the conveying assembly 2 32 are the same, the driving assembly 33 is arranged on the mounting seat 23, and the transmission assembly 34 is meshed with the driving assembly 33.

[0039] The driving component 33 can drive the conveying component 1 31 to move out of the lower clamping plate 24 and onto the pallet. When the positioning mechanism and the box pressing mechanism both press the stacked cartons, the driving component 33 can drive the conveying component 2 32 to operate synchronously with the conveying component 1 31 through the transmission component 34. At this time, under the action of the conveying component 1 31 and the conveying component 2 32, the carton can be driven to move along the diagonal direction of the lower clamping plate 24 to eliminate the gap between the cartons during the stacking process. At the same time, under the action of the positioning mechanism and the box pressing mechanism, the stacked cartons can be prevented from moving to ensure the neatness of the cartons when they are stacked. There is no need to use other equipment to push the entire layer of cartons to align, avoid large friction between the cartons, and thus prevent the printed matter on the cartons from being scratched or scratched.

[0040] Continue to refer Figures 1 to 3As shown, the conveying assembly 1 31 includes a conveyor belt 311, a transmission roller 312, a driving roller 313 and a transmission rod 314. There are multiple conveyor belts 311, and the multiple conveyor belts 311 are evenly spaced along the width direction of the lower clamping plate 24. The side of the conveyor belt 311 located at the edge is located in the same plane as the side of the lower clamping plate 24. The head end of the conveyor belt 311 passes through the mounting seat 23 and extends to the inside of the mounting seat 23.

[0041] There are two transmission rods 314, which are mounted at one end of the two driving rollers 313 located at the outermost edge. One end of the transmission rod 314 is rotatably connected to one side of the inner wall of the mounting seat 23, and a transmission wheel 317 is installed on the outer side of one end of the two transmission rods 314.

[0042] When the transmission rod 314 rotates, the two driving rollers 313 at the outermost edge can drive the conveyor belt 311 at the outermost edge to rotate. At the same time, the conveyor belt 311 at the outermost edge can drive the remaining conveyor belts 311 to rotate through the transmission roller 312, so as to drive the carton to move along the length direction of the lower clamping plate 24.

[0043] like Figure 2 and Figure 3 As shown, the outer side of the transmission roller 312 is rotatably connected to a plurality of brackets 2 316. In this embodiment, the number of brackets 2 316 is four. In other embodiments, the number of brackets 2 316 can be two, three or more. The brackets 2 316 are mounted on the top of the lower clamping plate 24. Both ends of the driving roller 313 are rotatably connected to brackets 1 315, which are mounted on the inner bottom wall of the mounting seat 23.

[0044] like Figures 1 to 3 As shown, the conveying assembly 2 32 includes a rotating rod 321, a rotating wheel 322, a circular gear 323 and a toothed belt 324. There are multiple rotating rods 321, and the multiple rotating rods 321 are respectively located between the multiple conveyor belts 311. One end of the rotating rod 321 passes through the mounting seat 23 and extends to the inside of the mounting seat 23. The outer side of one end of the rotating rod 321 is rotatably connected to a support frame, and the support frame on the rotating rod 321 is fixed to the inner bottom wall of the mounting seat 23. There are multiple groups of rotating wheels 322, and the multiple groups of rotating wheels 322 are respectively installed on the multiple rotating rods 321. There are multiple rotating wheels 322 in each group, and the multiple rotating wheels 322 are evenly spaced along the length direction of the rotating rod 321. When the rotating rod 321 rotates, it can drive the multiple rotating wheels 322 to rotate around the rotating rod 321, thereby driving the carton to move along the width direction of the lower clamping plate 24.

[0045] The number of the circular gears 323 is equal to the number of the rotating rods 321 . The circular gears 323 are installed at one end of the rotating rods 321 . The toothed belts 324 are meshedly connected to the outer sides of the plurality of circular gears 323 . The transmission assembly 34 is fixed to one of the rotating rods 321 .

[0046] like Figure 2 and Figure 3 As shown, the driving assembly 33 includes a motor 331, a bevel gear 1 332, a bevel gear 2 333 and a rotating shaft 334. The motor 331 is mounted on one side of the mounting seat 23, the bevel gear 1 332 is located inside the mounting seat 23, the driving shaft of the motor 331 is mounted on one end of the bevel gear 1 332, the bevel gear 2 333 is meshedly connected to one side of the bevel gear 1 332, the bevel gear 2 333 is mounted on the outside of the rotating shaft 334, and the two ends of the rotating shaft 334 are respectively rotatably connected to the two sides of the inner wall of the mounting seat 23, and the two ends of the rotating shaft 334 are both mounted on the outside of the two ends of the rotating shaft 334. In this embodiment, the transmission wheel 1 317 and the transmission wheel 2 335 are both pulleys, and the transmission wheel 1 317 and the transmission wheel 2 335 are connected by belt transmission. In other embodiments, the transmission wheel 1 317 and the transmission wheel 2 335 are both sprockets, and the transmission wheel 1 317 and the transmission wheel 2 335 are connected by chain transmission.

[0047] The motor 331 drives the rotating shaft 334 to rotate through the bevel gear 2 333 on the bevel gear 1 332 , and the rotating shaft 334 drives the transmission rod 314 on the transmission wheel 1 317 to rotate through the transmission wheel 2 335 , thereby driving the multiple conveyor belts 311 to rotate.

[0048] like Figure 3 and Figure 4 As shown, the transmission assembly 34 includes a bevel gear 341, a limiting shaft 1 342, a limiting cylinder 344 and a limiting shaft 2 346. The bevel gear 341 is meshed with the bevel gear 2 333, the limiting shaft 1 342 is mounted on one end of the bevel gear 341, and the outer side of the limiting shaft 1 342 is rotatably connected with a vertical plate 347, and the vertical plate 347 is mounted on the inner bottom wall of the mounting seat 23. The limiting shaft 1 342 and the limiting shaft 2 346 are rotatably connected through a connecting column, and the limiting cylinder 344 is slidably connected to the outer side of the limiting shaft 2 346, and the limiting shaft 2 346 is fixed to one of the circular gears 323. In this embodiment, the limiting shaft 1 342 and the limiting shaft 2 346 are both external spline shafts, and the limiting cylinder 344 is an internal spline cylinder, and the limiting cylinder 344 can slide from the limiting shaft 2 346 to the limiting shaft 1 342.

[0049] like Figure 1 and Figure 4As shown, the outer side of the limiting cylinder 344 is rotatably connected to a hinge seat 345, and an elastic member 343 is installed between the hinge seat 345 and the vertical plate 347. In this embodiment, the elastic member 343 is a spring, and in other embodiments, the elastic member 343 is an elastic sheet. The box pressing mechanism is hinged to the hinge seat 345.

[0050] When the box pressing mechanism is pressed on the carton, the box pressing mechanism can drive the limiting cylinder 344 to slide onto the limiting shaft 1 342 through the hinge seat 345. At this time, the motor 331 drives the bevel gear 3 341 to rotate through the bevel gear 2 333 on the bevel gear 1 332. The bevel gear 341 drives the limiting shaft 2 346 in the limiting cylinder 344 to rotate through the limiting shaft 1 342, so that the limiting shaft 2 346 drives one of the rotating rods 321 to rotate. At this time, under the action of the circular gear 323 and the toothed belt 324, the remaining rotating rods 321 rotate synchronously, so that the rotating wheels 322 on multiple rotating rods 321 rotate synchronously.

[0051] like Figure 1 , Figure 2 and Figure 4 As shown, the box pressing mechanism includes a sliding frame 51, a connecting rod 52, a threaded barrel 53, a pressing plate 54 and an articulated arm 55. The connecting seat 25 is slidably connected to the outside of the sliding frame 51, the connecting rod 52 is installed on the top of one side of the sliding frame 51, the threaded barrel 53 is threadedly connected to the outside of the bottom end of the connecting rod 52, and the pressing plate 54 is rotatably connected to the bottom end of the threaded barrel 53. By rotating the threaded barrel 53, the pressing plate 54 can be driven to move up and down to adjust the initial height of the pressing plate 54, so as to adapt to cartons of different heights. The pressing plate 54 is located at the bottom of one side of the upper clamping plate 26. The bottom of the sliding frame 51 is hinged with an articulated arm 55, and the bottom of the articulated arm 55 is hinged with the articulated seat 345 through a pin shaft, and the top of the mounting seat 23 is provided with a groove for the articulated arm 55 to slide.

[0052] like Figure 2 As shown, connecting blocks 56 are installed at the bottom of both sides of the sliding frame 51, and an elastic member 3 57 is installed at the bottom of the connecting block 56. In this embodiment, the elastic member 3 57 is a spring. In other embodiments, the elastic member 3 57 is an elastic sheet. The bottom end of the elastic member 3 57 is installed on the top of the mounting seat 23.

[0053] When the lower clamping plate 24 and the upper clamping plate 26 clamp the carton and move it downward, the pressure plate 54 contacts the stacked carton. At this time, as the lower clamping plate 24 and the upper clamping plate 26 continue to move downward, the sliding frame 51 gradually moves away from the mounting seat 23 under the action of the pressure plate 54. At this time, the sliding frame 51 drives the limiting cylinder 344 on the hinge seat 345 to slide onto the limiting shaft 1 342 through the hinge arm 55, so that the rotating rod 321 can rotate. When the pressure plate 54 presses the stacked carton, it can prevent the carton on the lower clamping plate 24 from pushing the stacked carton to move during the movement along the width direction of the lower clamping plate 24.

[0054] like Figure 1 and Figure 2 As shown, the positioning mechanism includes a positioning plate 41, a fixing rod 42 and a movable plate 43. The positioning plate 41 is located at the front bottom of the upper clamping plate 26. The bottoms of the positioning plate 41 and the pressing plate 54 are both rollingly connected with a plurality of balls to prevent the carton from being scratched during the movement of the positioning plate 41 and the pressing plate 54. The length of the pressing plate 54 is less than the length of the positioning plate 41. There are multiple fixing rods 42, and the multiple fixing rods 42 are arranged at equal intervals along the width direction of the lower clamping plate 24. One end of the multiple fixing rods 42 is installed on the top of the positioning plate 41, and the other end of the multiple fixing rods 42 is installed on one side of the movable plate 43. Both sides of the top of the movable plate 43 are slidably connected with sliding rods 44. The bottom end of the sliding rod 44 passes through the movable plate 43 and is installed on the top of the upper clamping plate 26. An elastic member 2 45 is installed between the upper clamping plate 26 and the movable plate 43. In this embodiment, the elastic member 2 45 is a spring.

[0055] Working principle: When stacking cartons, the cartons are transported to the conveyor belt 311 through an external conveying device. At this time, the conveyor belt 311 is driven by the motor 331 to rotate so as to guide the cartons completely to the top of the lower clamping plate 24. Then the electric slide rail 21 drives the upper clamping plate 26 to approach the carton through the connecting seat 25 to clamp the carton. After the carton is clamped, the carton is moved to the pallet by the robot arm 11. Then the electric slide rail 21 drives the upper clamping plate 26 to move up through the connecting seat 25 to release the clamping of the carton. At this time, the motor 331 rotates in the opposite direction so that the conveyor belt 311 drives the carton to be stacked on the pallet.

[0056] When stacking the second carton, as the clamped carton moves downward, the upper clamping plate 26 drives the positioning plate 41 on the fixed rod 42 to press on the top of the first carton through the movable plate 43 on the slide rod 44, the elastic member 45 is stretched, and then the upper clamping plate 26 is moved up to release the clamping of the carton. At this time, the positioning plate 41 is still pressed on the carton, and then the second carton is driven to approach the first carton through the conveyor belt 311. At the same time, the robot arm 11 drives the lower clamping plate 24 to move away from the first carton, so that the second carton is stacked on the pallet and the two cartons are close to each other to eliminate the gap between the two cartons.

[0057] As the number of cartons stacked increases, when the positioning plate 41 and the pressure plate 54 are both pressed on the stacked cartons, the sliding frame 51 gradually moves away from the mounting seat 23 under the action of the pressure plate 54. At this time, the sliding frame 51 drives the limiting cylinder 344 on the hinge seat 345 to slide onto the limiting shaft 342 through the hinge arm 55. At this time, the motor 331 can drive the rotating rod 321 and the conveyor belt 311 to rotate at the same time, so that the conveyor belt 311 and the rotating wheel 322 rotate at the same time. At this time, the carton moves along the diagonal direction of the lower clamping plate 24 to approach the two adjacent stacked cartons, thereby eliminating the gap between the cartons. When the cartons are aligned, the mechanical arm 11 drives the lower clamping plate 24 away from the paper When the lower clamping plate 24 moves away from the carton, the pressing plate 54 gradually separates from the stacked carton. When the pressing plate 54 is completely separated from the carton, the sliding frame 51 is reset. At this time, the sliding frame 51 drives the limiting cylinder 344 on the hinge seat 345 to separate from the limiting shaft 342 through the hinge arm 55, so that the rotating wheel 322 stops rotating. At the same time, the conveyor belt 311 continues to convey the carton, so that the carton is close to the stacked carton until the carton completely falls from the conveyor belt 311. The gaps between the cartons can be automatically eliminated through the conveyance of the conveyor belt 311 and the rotation of the rotating wheel 322. There is no need to use external equipment to push the cartons to tidy up the cartons, so as to avoid scratches or scratches on the printed matter on the cartons.

A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
