Description

Technical Field

[0001] The present invention relates to the technical field of packaging, and in particular to a material stacking mechanism and a case packing machine. Background Art

[0002] At present, one of the key factors limiting the speed of the case packing production line is the matching between the material arrangement speed and the unpacking and packing speed. This is especially true for side-push mechanical case packing. Before packing, the empty case must be tilted sideways. After the materials are arranged, the arranged materials are pushed from the side during packing. After packing, the case must be turned back to the right position before subsequent processes such as conveying and sealing can be carried out. As a result, the speed of the existing case packing machine is low. If the speed of pushing the materials into the case is simply increased, the improvement in the packing speed is very limited. Increasing the speed too much can easily cause the arranged materials to scatter during the pushing process, resulting in case packing failure or even case jamming. Summary of the Invention

[0003] The purpose of the present invention is to provide a material stacking mechanism and a box packing machine, which can realize the stacking of boxed materials, and greatly improve the boxing efficiency while ensuring the stability and orderliness of the boxed materials during the boxing process.

[0004] The technical solution adopted in the present invention is:

[0005] A material stacking mechanism comprises a stacking buffer component, a stacking lifting component and a stacking conveying component, wherein the stacking lifting component is arranged below the stacking buffer component;

[0006] The conveying channel of the stacking conveying component serves as a material arrangement channel, and the stacking buffer component includes stacking side components respectively arranged on both sides of the material arrangement channel, and the two groups of stacking side components are provided with outward-turning stacking shelves, and the stacking shelves on both sides are relatively arranged side by side. In the initial position, the width distance between the stacking shelves on both sides is less than the width of the arranged materials, and the width distance between the stacking shelves on both sides after being flipped outward is greater than or equal to the width of the arranged materials. Above the stacking shelves on both sides is the material cache placement position, and the stacking shelves are connected with a return spring assembly, which is used to flip the stacking shelves back to the initial position. The stacking jacking component is arranged below the material arrangement channel for lifting the materials arranged in the material arrangement channel to the material cache placement position on the stacking shelves, and the lifting path of the stacking jacking component passes through the longitudinal gap on the conveying surface of the stacking conveying component for lifting the materials arranged in the material arrangement channel.

[0007] Preferably, the material stacking mechanism further includes a cache pushing component, which is arranged above or to the side of the stacking cache component and is used to push out the material on the material cache placement position.

[0008] Preferably, the stack conveying component comprises at least two belts or chains arranged longitudinally side by side, the stack top plate of the stack lifting component is arranged in the gap between adjacent belts or adjacent chains, and the lifting path of the stack lifting component passes through the gap between adjacent belts or adjacent chains.

[0009] Preferably, the stacked shelf bars are in a 7-shape, with the 7-shaped opening facing outwards.

[0010] Preferably, the stack lifting component includes a stack top plate and a lifting and pushing mechanism, and the lifting and pushing mechanism is connected to the stack top plate to drive the stack top plate to move up and down.

[0011] Preferably, the lifting and pushing mechanism includes a stacking lifting bracket, a stacking motor, and a crank slider connecting rod mechanism, wherein the stacking motor is connected to the stacking lifting bracket via the crank slider connecting rod mechanism, and the stacking top plate is arranged on the stacking lifting bracket;

[0012] The crank slider connecting rod mechanism includes a laminated jacking slide rail, a jacking slider seat, a laminated jacking connecting rod and a laminated jacking crank. The laminated jacking slide rail is arranged vertically, and a slider is provided on the laminated jacking slide rail. The slider is set on the jacking slider seat, and the jacking slider seat is fixedly arranged. The output end of the laminated motor is hinged to one end of the laminated jacking connecting rod through the laminated jacking crank, and the other end of the laminated jacking connecting rod is hinged to the laminated jacking slide rail, and the top of the laminated jacking slide rail is connected to the laminated jacking bracket.

[0013] Preferably, the stacking side assembly includes a stacking guide plate, a stacking baffle assembly, a stacking shaft, and a stacking shaft seat. The stacking baffle assembly and the return spring assembly are disposed on the stacking guide plate. The stacking shaft is disposed on the stacking guide plate via the stacking shaft seat. The stacking shelf bar is disposed on the stacking shaft. The stacking shelf bar can rotate with the stacking shaft. The return spring assembly is connected to the stacking shaft or the stacking shelf bar. The stacking baffle assembly and the stacking shelf bar are staggered.

[0014] The inner and outer sides of the stacked shelf bars are respectively provided with stacked shelf bar limiting seats and stacked flip plate limiting blocks, which are respectively used to limit the two flip limit positions of the stacked shelf bars.

[0015] Preferably, the laminated baffle assembly includes a lower plate and a plurality of baffles sequentially spaced apart on the lower plate along the length direction of the material arrangement channel, the lower plate is arranged on the inner side of the laminated shelf bar, a plurality of gaps are sequentially spaced apart on the laminated shelf bar along the length direction of the material arrangement channel, each baffle is respectively arranged corresponding to each gap on the laminated shelf bar, and the baffles of the laminated movable baffle assembly pass through the corresponding gap;

[0016] The stacking baffle assemblies on both sides are respectively a stacking fixed baffle assembly and a stacking movable baffle assembly. The stacking movable baffle assembly also includes a lifting mechanism connected to the lower plate. When the lifting mechanism drives the stacking movable baffle assembly to rise, the upper end of the baffle bar of the stacking movable baffle assembly passes through the gap between the stacking shelves and is higher than the upper end surface of the stacking shelves. When the lifting mechanism drives the stacking movable plate component to descend, the upper end of the baffle bar of the stacking movable baffle is lower than the upper end surface of the stacking shelves. When boxed materials enter the material arrangement channel, the lifting mechanism rises and lifts the baffle bar of the stacking movable baffle assembly. When the boxed materials are full, the corresponding sensor is triggered, and the stacking lifting component lifts the arranged boxed materials and causes the arranged boxed materials to fall to the material buffer placement position on the stacking spacer bars. The two sides of the boxed materials are protected by the baffle bars of the stacking movable baffle assembly and the baffle bars of the stacking fixed baffle assembly. The baffle bars of the stacking movable baffle assembly and the stacking fixed baffle assembly limit the movable range of the boxed materials at both ends. When the stacking lifting component moves downward, the boxed materials restricted by the barriers of the stacking movable baffle assembly and the stacking fixed baffle assembly will not scatter, which is a key factor in ensuring the successful stacking of the boxed materials. The above actions are repeated cyclically, and the stacking lifting component lifts the materials arranged in the material arrangement channel to the material buffer placement position, and stacks them on the material buffer placement position according to the stacking height inside the carton.

[0017] The return spring assembly includes a return spring support and a return spring, wherein the return spring support is arranged transversely, the inner end of the return spring support is connected to the outer side of the laminated shelf, and the return spring support is connected to the return spring;

[0018] The output tail end of the material arrangement channel is provided with a laminated material discharge stop assembly, and the inlet end of the material arrangement channel is provided with a laminated material feed stop assembly.

[0019] The stacking material discharging stop assembly includes a telescopic cylinder and a discharging stop plate, which are connected to the discharging stop plate. When the materials are normally arranged in the material arrangement channel, the telescopic cylinder drives the discharging stop plate to extend into the material arrangement channel. The discharging stop plate is located at the top of the material arrangement channel, blocks the materials at the top of the stacking conveying component, and continuously conveys the materials toward the top of the material arrangement channel. When it is detected that the materials on the stacking conveying component are vertical, tilted, or irregular, the telescopic cylinder drives the discharging stop plate to retract outside the material arrangement channel, and the stacking conveying component continues to operate, conveying and discharging the irregular materials from the top of the material arrangement channel.

[0020] The stacked feed baffle assembly includes a telescopic cylinder and a feed baffle, and the telescopic cylinder is connected to the feed baffle; when material is to be input into the material arrangement channel, the telescopic cylinder drives the feed baffle to retract, opens the entrance of the material arrangement channel, and allows the material to enter the material arrangement channel; when the material in the material arrangement channel is arranged and the input of material into the material arrangement channel is to be stopped, the telescopic cylinder drives the feed baffle to extend, closes the material arrangement channel, and prevents the material from entering the material arrangement channel.

[0021] The material stacking mechanism further includes a cache pushing component and a material grouping cache component, which are respectively arranged on both sides of the material cache placement position of the material stacking mechanism, and the cache pushing component is used to push the material on the material cache placement position to the material grouping cache component;

[0022] The material grouping cache component includes a cache bracket, a cache grid assembly, a cache cylinder assembly and a cache cylinder connecting seat. A slide rail is arranged on the cache bracket. The cache cylinder assembly is set on the double slide rail through the cache guide rail base and can move back and forth along the slide rail. The cache cylinder assembly is fixed on the cache bracket. The movable end of the cache cylinder assembly is connected to the cache grid assembly through the cache cylinder connecting seat; the cache cylinder assembly drives the cache grid assembly to move back and forth along the slide rail. When the stacked boxed material triggers the cache push trigger sensor, the stacked cache push assembly pushes the boxed material to the cache grid assembly, and drives the cache grid assembly connected to the cache cylinder connecting seat through the cache cylinder to transport the boxed material to the input end of the side push boxing mechanism. Then, according to the production rhythm frequency, two side push boxings are completed through the side push component to reduce the stacking frequency of the stacking mechanism.

[0023] Furthermore, the slide rails on the cache bracket are double slide rails.

[0024] A material stacking method using the material stacking mechanism described above comprises the following steps:

[0025] Step 1: The material enters the material arrangement channel and is arranged;

[0026] Step 2: After the incoming stacking trigger sensor detects that the materials are arranged in the set columns, the stacking lifting component lifts the materials arranged in the stacking channel upward. During the lifting process, the materials squeeze and flip the stacking shelves outward until the materials rise above the stacking shelves. The stacking shelves are then acted upon by the return spring assembly to return to their initial positions, and the materials fall to the material buffer placement position on the two stacking shelves;

[0027] Step 3: Repeat steps 1 and 2, and lift up the materials previously placed on the material buffer placement positions on the stacking shelves on both sides and stack them until the material stacking reaches the set number of layers.

[0028] A cartoning machine comprises the material stacking mechanism, the side-pushing cartoning mechanism and the stacked material conveying mechanism described above, wherein the input end of the material stacking mechanism is connected to the output end of the stacked material conveying mechanism, and the side-pushing cartoning mechanism is connected to the output end of the material stacking mechanism; the input end of the material stacking mechanism is a material arrangement channel, and the side-pushing cartoning mechanism is used to push the stacked materials on the output end of the material stacking mechanism into the carton of the side-pushing cartoning mechanism.

[0029] The beneficial effects of the present invention are:

[0030] The stacking rack is a stack of materials which are stacked together and which are then stacked together, and the stacking racks are then moved back to their original positions by the return springs. The .... The stacking racks are then moved back to their original positions. The stacking racks are then moved back to their original positions. The stacking racks are then moved back to their original positions. The stacking racks are then moved back to their original positions. The stacking racks are then moved back to their original positions. The stacking racks are then moved back to their original positions. The stacking racks are then moved back to their original positions. The stacking racks are then moved back to their original positions. The packing efficiency is greatly improved. The material arrangement channel does not have to wait for the arranged materials to be packed before it can start arranging. The arranged materials can be placed in the material buffer and wait for the packing machine to unpack them at any time for packing. Under the premise of ensuring the quality of material arrangement and packing, the material arrangement waiting time is shortened, and the material arrangement waiting time and packing timing are quickly matched, thereby improving the efficiency of the packing production line as a whole. In addition, the present invention forms an upper and lower double-layer position relationship between the material arrangement channel and the material buffer placement position through the stacked buffer components, which effectively shortens the jacking distance and time, and is particularly suitable for side-push packers. The arrangement of the stacked shelves is simple in structure and cleverly arranged, which maximizes the use of the hierarchical distribution in space, effectively avoids the side space, and reduces the floor space.

When boxed materials enter, the lifting mechanism 2-25 raises the barrier strip of the laminated movable baffle assembly 2-24. When the boxed materials are full, the corresponding sensor is triggered, and the laminated lifting assembly 2-2 lifts the arranged boxed materials and causes them to fall to the material buffer placement position on the laminated spacer bar. The two sides of the boxed materials are protected by the barrier strips of the laminated movable baffle assembly 2-24 and the laminated fixed baffle assembly 2-21, respectively. The barrier strips of the laminated movable baffle assembly 2-24 and the laminated fixed baffle assembly 2-21 limit the movable range of the boxed materials on both sides. When the stacking lifting component 2-2 moves downward and retracts, the boxed materials limited by the stacking movable baffle assembly 2-24 and the stacking fixed baffle assembly 2-21 will not scatter. When the stacking lifting component 2-2 retracts, the materials fall back to the material buffer placement position on the stacking shelf 2-10. At this time, the incoming material stacking is completed. After the buffer push trigger sensor 2-32 receives the signal, the cylinder in the lifting mechanism 2-25 retracts, and the lifting mechanism 2-25 drives the stacking movable baffle assembly 2-24 to descend. The upper end of the baffle of the stacking movable baffle assembly 2-24 is lower than the upper end surface of the stacking shelf 2-10, which is convenient for arrangement. The good materials are pushed out from the discharge side by the buffer pushing component 2-3; when the arranged materials are pushed out from the material buffer placement position, the buffer pushing component 2-3 retracts, and the lifting mechanism 2-25 rises to continue the next round of material stacking. The baffles on both sides serve as guardrails of the material arrangement channel to facilitate the material to be pushed from the material arrangement channel into the material buffer placement position to prevent the material from tilting or the arrangement formation from being scattered during the lifting process; the above actions are repeated in a cycle, and the stacking lifting component 2-2 lifts the arranged materials in the material arrangement channel to the material buffer placement position, and stacks them on the material buffer placement position according to the stacking height inside the carton.

[0097] The lifting mechanism 2-25 includes a lifting cylinder, which is connected to the lower plate and is arranged on the stacking guide plate 2-20 through a cylinder mounting plate.

[0098] Furthermore, a stacking shelf bar limiting seat 2-36 and a stacking flap limiting block 2-39 are respectively provided on the inner and outer sides of the stacking shelf bar 2-10, which are respectively used to limit the two flip limit positions of the stacking shelf bar 2-10.

[0099] Furthermore, the return spring assembly 2-11 includes a return spring pillar 2-26 and a return spring 2-27. The return spring pillar 2-26 is arranged laterally on the return spring mounting block 2-37. The return spring mounting block 2-37 is fixed on the laminated guide plate 2-20. The inner end of the return spring pillar 2-26 is connected and in contact with the outer side of the laminated shelf 2-10. The return spring pillar 2-26 is connected to the return spring 2-27. The return spring 2-27 is sleeved on the return spring pillar 2-26. The two ends of the return spring 2-27 are respectively connected to the return spring pillar 2-26 and the return spring mounting block 2-37.

[0100] The output tail end of the material arrangement channel is provided with a laminated discharge stop assembly 2-7, and the inlet end of the material arrangement channel is provided with a laminated feed stop assembly 2-4;

[0101] The stacking material discharging stop assembly 2-7 includes a telescopic cylinder and a discharging stop plate, which are connected to the discharging stop plate. When the materials are normally arranged in the material arrangement channel, the telescopic cylinder drives the discharging stop plate to extend into the material arrangement channel. The discharging stop plate is located at the top of the material arrangement channel, blocks the materials at the top of the stacking conveying component, and continuously conveys the materials toward the top of the material arrangement channel. When it is detected that the materials on the stacking conveying component are vertical, tilted, or uneven, the telescopic cylinder drives the discharging stop plate to retract outside the material arrangement channel, and the stacking conveying component continues to operate, conveying and discharging the uneven materials thereon from the top of the material arrangement channel.

[0102] The stacked feed baffle assembly 2-4 includes a telescopic cylinder and a feed baffle, which is connected to the feed baffle; when material is to be input into the material arrangement channel, the telescopic cylinder drives the feed baffle to retract, opens the entrance of the material arrangement channel, and allows the material to enter the material arrangement channel; when the material in the material arrangement channel is arranged and the input of material into the material arrangement channel is to be stopped, the telescopic cylinder drives the feed baffle to extend, closes the material arrangement channel, and prevents the material from entering the material arrangement channel.

[0103] like Figures 30-33 As shown, the material stacking mechanism further includes a cache pushing component 2-3 and a material grouping cache component 3, which are respectively arranged on both sides of the material cache placement position of the material stacking mechanism. The cache pushing component 2-3 is used to push the material on the material cache placement position to the material grouping cache component 3;

[0104] The material marshalling cache component includes a cache bracket 2-43, a cache grid assembly 2-45, a cache cylinder assembly 2-46 and a cache cylinder connecting seat 2-47. A slide rail is arranged on the cache bracket 2-43. The cache cylinder assembly 2-46 is set on the double slide rail 2-44 through the cache guide rail base 2-42 and can move back and forth along the slide rail. The cache cylinder assembly 2-46 is fixed on the cache bracket 2-43. The movable end of the cache cylinder assembly 2-46 is connected to the cache grid assembly 2-44 through the cache cylinder connecting seat 2-47. 5 connection; the cache cylinder assembly 2-46 drives the cache grid assembly 2-45 to move back and forth along the slide rail. When the stacked boxed materials trigger the cache push trigger sensor 2-32, the stacking cache push assembly pushes the boxed materials to the cache grid assembly 2-45, and drives the cache grid assembly 2-45 connected to the cache cylinder connecting seat through the cache cylinder to transport the boxed materials to the input end of the side push boxing mechanism. Then, according to the production rhythm frequency, two side push boxings are completed by the side push component to reduce the stacking frequency of the stacking mechanism.

[0105] Furthermore, the slide rails on the cache bracket 2-43 are double slide rails 2-44.

[0106] A material stacking method using the above material stacking mechanism comprises the following steps:

[0107] Step 1: The material enters the material arrangement channel and is arranged;

[0108] Step 2: After the incoming material stacking trigger sensor 2-33 detects that the materials are arranged in the set column, the stacking lifting component 2-2 lifts the materials arranged in the stacking channel upward. During the lifting process, the materials squeeze and flip the stacking shelves 2-10 outward until the materials rise above the stacking shelves 2-10. The stacking shelves 2-10 are then returned to their initial positions by the return spring assembly 2-11, and the materials fall to the material buffer placement position on the two stacking shelves 2-10.

[0109] Step 3: Repeat steps 1 and 2, and stack the materials previously placed in the material buffer storage positions on the stacking shelves 2-10 on both sides until the materials are stacked to the set number of layers;

[0110] Step 4: After the buffer push trigger sensor 2-32 detects that the material has been stacked to the set number of layers, the buffer push component 2-3 pushes the stacked multi-layer material to the next process.

[0111] A cartoning machine includes the material stacking mechanism, the side-pushing cartoning mechanism, and the stacked material conveying mechanism 1 described above. The input end of the material stacking mechanism is connected to the output end of the stacked material conveying mechanism 1, and the side-pushing cartoning mechanism is connected to the output end of the material stacking mechanism; the input end of the material stacking mechanism is a material arrangement channel, and the side-pushing cartoning mechanism is used to push the stacked materials on the output end of the material stacking mechanism into the carton of the side-pushing cartoning mechanism.

[0112] Furthermore, the material pushing end of the cache pushing component 2-3 of the material stacking mechanism is docked with the cache grid assembly 2-45 of the material grouping cache component 3, and the cache grid assembly 2-45 of the material grouping cache component 3 is docked with the input end of the side pushing packing mechanism.

[0113] An incoming material clamping box device 2-31 is provided on the stacked material conveying mechanism 1, and the best position is to be arranged at the output end of the stacked material conveying mechanism 1; an incoming material full sensor 2-29 is provided on the stacked material conveying mechanism 1, which is set at the incoming material full sensor 2-29 detection position, and an incoming material discharge sensor is provided at the output end of the stacked material conveying mechanism 1 or the input end of the stacked conveying component, which is set at the incoming material discharge sensor detection position.

[0114] Furthermore, the laminated material conveying mechanism 1 is a laminated material conveying chain network component, the laminated conveying component is a laminated belt component 2-5, the conveying channel or conveying surface of the laminated belt component 2-5 serves as a material arrangement channel, and the output end of the laminated material conveying chain network component is connected to the input end of the laminated belt component 2-5; the laminated material conveying mechanism 1 and the laminated conveying component can be driven by a common motor.

[0115] When the stacking belt assembly 2-5 is full, the boxed material at the stacking belt assembly 2-5 triggers the incoming stacking trigger sensor 2-33. At this time, the stacking lifting assembly 2-2 begins to operate, and the stacking top plate 2-12 pushes the boxed material upward. The boxed material presses against the stacking shelf 2-10 in the stacking fixed side assembly 2-6 and the stacking movable side assembly 2-9. The fixed side stacking shelf return spring and the movable side stacking shelf return spring act to lift the boxed material to the upper surface of the stacking shelf 2-10, completing the first layer of material stacking. At this time, the buffer push trigger sensor 2-32 has not yet been triggered. The stacking top plate 2-12 continues to reciprocate up and down, stacking the second layer until the boxed material triggers the buffer push trigger sensor 2-32. At this time, the cylinder in the lifting mechanism 2-25 retracts and drives the upper end of the movable side baffle to move down to below the upper end surface of the stacking partition bar, and then the cache push cylinder in the cache push component 2-3 starts to move to push the stacked boxed materials to the material grouping cache component 3.

[0116] The stacking lifting component 2-2 is a crank-connecting rod mechanism driven by a motor. When the boxed material enters the stacking belt component 2-5, the upper plane of the stacking top plate 2-12 should be in the same plane as the upper plane of the stacking belt. If they are not in the same plane, the stacking top plate 2-12 continues to move downward under the drive of the stacking lifting motor, and at the same time, the stacking sensor detection piece 2-8 moves downward in a circular motion until the stacking lifting lower limit sensor 2-35 detects the stacking sensor detection piece 2-8. At this time, the upper plane of the stacking top plate 2-12 and the upper plane of the stacking belt are in the same plane, ensuring that the boxed material enters the stacking belt component 2-5 smoothly and steadily. After the boxed material enters the stacking belt component 2-5 smoothly and steadily, it receives feedback from the incoming material stacking trigger sensor 2-33, and the stacking jacking motor continues to drive the crank-connecting rod mechanism to operate. At the same time, stacking is also carried out in this process, and the stacking sensor detection piece 2-8 continues to make circular motion. When the stacking upper limit sensor detects the stacking sensor detection piece 2-8, the boxed material is stacked to the stacking shelf 2-10, and the stacking action is completed.

[0117] Working principle of the present invention:

[0118] like Figures 5-7 The mechanism shown is an automated material stacking mechanism, which can realize the stacking of boxed materials, while ensuring the stability and orderliness of the boxed materials during the packing process, greatly improving the packing efficiency.

[0119] The specific implementation is as follows: the material is boxed material, and the chain network is driven by the motor, pulley and roller in the stacking incoming material conveying chain network component to realize the transportation of boxed materials; the boxed materials are smoothly fed into the stacking belt component 2-5 through the stacking feed stop component 2-4; the stacking belt component 2-5 and the stacking incoming material conveying chain network component share the same power to realize the continuity and consistency of the incoming boxed materials; the stacking discharge stop component 2-7 blocks the boxed materials that neatly enter the stacking belt component 2-5, preparing for the stacking of boxed materials, and then drives the stacking lifting motor in the stacking lifting component 2-2 to drive the stacking lifting slide rail 2-16 placed in the crank connecting rod mechanism to move up and down to realize the stacking of the materials. The top plate of the boxed materials reciprocates up and down; when the boxed materials are pushed upward by the top plate, the boxed materials squeeze the stacking shelves 2-10 in the stacking fixed side assembly 2-6 and the stacking movable side assembly 2-9. The return spring connected to the stacking shelves 2-10 acts to lift the boxed materials to the upper surface of the stacking shelves 2-10, thereby achieving the stacking of the boxed materials; after the buffer push trigger sensor 2-32 receives a signal, the cylinder in the lifting mechanism 2-25 retracts, and the lifting mechanism 2-25 drives the stacking movable plate component to descend. The upper end of the baffle of the stacking movable baffle descends to below the upper end surface of the stacking shelves 2-10, facilitating the arranged materials to be pushed out from the discharge side by the buffer push component 2-3. The buffer push component 2-3 then pushes the boxed materials to the material grouping buffer component 3; through the action of multiple cylinders in the material grouping buffer component 3, the stacked boxed materials are transported to the side push filling position, waiting for the boxed materials to be boxed.

[0120] like Figures 8-10 As shown, when the boxed materials are full in the laminated incoming material conveying chain network component and the laminated belt component 2-5, the boxed materials will trigger the incoming material full sensor 2-29, and the received signal is fed back to start the cylinder in the incoming material clamping device 2-31, and the cylinder extends, and the clamping block placed on the cylinder clamps the boxed materials, and the boxed materials are no longer fed into the laminated belt component 2-5.

[0121] like Figures 11-14As shown, a buffer push trigger sensor 2-32 is provided on one side of the material buffer placement position, and an incoming material stacking trigger sensor 2-33 is provided on the material arrangement channel of the stacking buffer component 2-1. When the stacking belt component 2-5 is full, the boxed carton material at the stacking belt component 2-5 triggers the incoming material stacking trigger sensor 2-33. At this time, the stacking lifting component 2-2 begins to operate, and the stacking top plate 2-12 pushes the boxed material upward. The boxed material presses against the stacking shelf 2-10 in the stacking fixed side component 2-6 and the stacking movable side component 2-9. The fixed side stacking shelf return spring and the movable side stacking shelf return spring act to lift the boxed material to the upper surface of the stacking shelf 2-10, completing the first layer of material stacking. At this time, the buffer push trigger sensor 2-32 has not yet been triggered, and the top plate continues to reciprocate up and down, stacking the second layer until the boxed material triggers the buffer push trigger sensor 2-32. At this time, the cylinder in the lifting mechanism 2-25 retracts and drives the upper end of the movable side baffle to move down to below the upper end surface of the stacking partition bar, and then the cache push cylinder in the stacking cache push assembly starts to move to push the stacked boxed carton materials to the material grouping cache component 3.

[0122] like Figures 15-17 As shown, the stacking lifting component 2-2 is a crank-connecting rod mechanism driven by a motor. When the boxed material enters the stacking belt component 2-5, the upper plane of the stacking top plate 2-12 should be in the same plane as the upper plane of the stacking belt. If they are not in the same plane, the stacking top plate 2-12 continues to move downward under the drive of the stacking lifting motor, and at the same time, the stacking sensor detection piece 2-8 moves downward in a circular motion until the stacking lifting lower limit sensor 2-35 detects the stacking sensor detection piece 2-8. At this time, the upper plane of the stacking top plate 2-12 and the upper plane of the stacking belt are in the same plane, ensuring that the boxed material enters the stacking belt component 2-5 smoothly and steadily. After the boxed material enters the stacking belt component 2-5 smoothly and steadily, it receives feedback from the incoming material sensor 2-40, and the stacking jacking motor continues to drive the crank-connecting rod mechanism to operate. At the same time, stacking is also carried out in this process, and the stacking sensor detection piece 2-8 continues to make circular motion. When the stacking upper limit sensor detects the stacking sensor detection piece 2-8, the boxed carton material is stacked on the stacking spacer and the stacking action is completed.
