Description

Technical Field

[0001] The invention relates to the technical field of packaging machinery, in particular to an accumulation device and packaging equipment. Background Art

[0002] After completing the basic packaging of the products, many existing commodities (such as instant noodles, milk, etc.) need to be packaged in boxes. Since the commodities in the packaging box are usually distributed in multiple layers, manual layered packing is usually required during the packing process. As a result, the labor intensity of workers in the packing process is high, the packing efficiency is low, and there are great safety hazards. Therefore, there is an urgent need for an accumulation device and packaging equipment that can automatically accumulate commodities in layers instead of manually, improve packing efficiency, and reduce safety hazards. Summary of the invention

[0003] In view of the above problems in the prior art, the present application provides an accumulation device and packaging equipment, which can automatically accumulate materials (commodities) in layers instead of manually, improve packing efficiency, and reduce safety hazards.

[0004] A first aspect of the present application provides an accumulation device, comprising: a conveying mechanism, the conveying mechanism having a first conveying roller, the end of the first conveying roller is connected to an accumulation station, and the first conveying roller is used to convey materials to the accumulation station; an accumulation mechanism, the accumulation mechanism having a lifting member and a first driving cylinder, the first driving cylinder is transmission-connected to the lifting member to drive the lifting member to rise and fall; the lifting member is located at the accumulation station, after the first conveying roller conveys a predetermined amount of the material to the lifting member, the first driving cylinder drives the lifting member to rise or fall, and accordingly, the first conveying roller conveys the predetermined amount of the material to below or above the material on the lifting member.

[0005] From the above, after the conveying mechanism conveys the material to the lifting member of the accumulation station through the first conveying roller, the lifting member and the material can be driven up or down by the first driving cylinder, thereby vacating the accumulation station. Then, the material can be conveyed to the accumulation station by the first conveying roller, so that another layer of material can be formed. In this way, the material can be automatically accumulated in layers instead of manually, thereby improving the packing efficiency and reducing safety hazards.

[0006] As a possible implementation of the first aspect, the lifting member has a multi-layer structure, each layer is open on the side facing the first conveying roller, and when the first driving cylinder drives the lifting member to rise and fall so that the layers of the lifting member are aligned with the first conveying roller, the conveying mechanism drives the material to enter the layers of the lifting member.

[0007] As described above, by setting the lifting member into a multi-layer structure, after the first driving cylinder drives each layer of the lifting member to align with the first conveying roller, the material can be conveniently transported to each layer of the lifting member through the first conveying roller, so that the material forms a multi-layer arrangement.

[0008] As a possible implementation of the first aspect, the accumulation mechanism also has a second conveyor roller, which is located at the accumulation station and connected to the end of the first conveyor roller, and is used to convey the material provided by the first conveyor roller; the lifting member includes: a mounting plate, which is located below the second conveyor roller, and the mounting plate is transmission-connected to the first drive cylinder to drive the mounting member to rise and fall; a supporting plate, which is mounted on the mounting plate to divide the space above the mounting plate into multiple layers in the vertical direction, and the supporting plate has multiple supporting arms on each layer, and the supporting arms extend in the horizontal direction and are respectively located between the conveyor rollers of the second conveyor roller.

[0009] From the above, by setting the second conveyor roller at the accumulation station, the material provided by the first conveyor roller can be conveyed. As a result, it is convenient to form multiple rows of materials at the accumulation station, and the stability of the materials when conveyed at the accumulation station is improved. In addition, by setting multiple supporting arms between the conveying rollers of the second conveyor roller, the supporting arms can pass through the second conveyor roller when the driving type of the first driving cylinder rises and falls, thereby avoiding the impact between the second conveyor roller and the supporting arms.

[0010] As a possible implementation of the first aspect, the accumulation device also includes a pushing mechanism, which includes: a pushing plate, which is arranged above the second conveying roller and has a plurality of pushing arms, which extend downward and are respectively located between the supporting arms; a transmission belt, which is arranged along the extension direction of the supporting arms and is transmission-connected to the pushing plate to drive the pushing plate to move along the extension direction of the supporting arms.

[0011] As described above, by arranging the transmission belt along the extension direction of the support arm, the push plate is connected to the transmission belt, so that the push plate can be driven to move along the extension direction of the support arm. By arranging the push arm between the support arms, when the push plate is driven to move along the extension direction of the support arm, the push arm can push the materials on the upper and lower layers of the support arm at the same time, thereby improving the packing efficiency.

[0012] As a possible implementation of the first aspect, the lifting member is in the shape of a plate, and the first driving cylinder is used to drive the lifting member to rise and be flush with or descend with the first conveying roller; the accumulation mechanism also includes: a pallet plate, which is horizontally arranged and located on one side of the accumulation station; a second driving cylinder, which is transmission-connected to the pallet plate, and drives the lifting member to move to the end of the first conveying roller after it descends.

[0013] From the above, after the first driving cylinder drives the lifting member to rise and be flush with the first conveying roller, the first conveying roller conveys the material onto the lifting member to form the first layer of material. After the first driving cylinder drives the lifting member to descend, the accumulation station can be vacated so that after the second driving cylinder drives the inserting plate to move to the end of the first conveying roller, the first conveying roller conveys the material onto the inserting plate to form the second layer of material.

[0014] As a possible implementation of the first aspect, the accumulation device also includes a cardboard bin mechanism, which is used to provide cardboard; the accumulation mechanism also includes: a cardboard pallet, which is located at the other side of the accumulation station, and the cardboard provided by the cardboard bin mechanism is located on the cardboard pallet; a cardboard push plate, which is located at a position where the cardboard pallet is away from the accumulation station; and a third drive cylinder, which is transmission-connected to the cardboard push plate and drives the cardboard push plate to push the cardboard to the position of the accumulation station.

[0015] As shown above, after the first driving cylinder drives the lifting member and the material to descend, the cardboard push plate can push the cardboard provided by the cardboard bin mechanism to the accumulation station. Thus, a layer of cardboard can be added between two layers of material, so that each layer of material can be more stable after the material accumulation is completed.

[0016] As a possible implementation of the first aspect, the cardboard bin mechanism includes: a cardboard bin, which is located above the cardboard pallet and is used to store cardboard; a suction cup, which is located below the cardboard bin and is used to absorb the cardboard in the cardboard bin from the bottom of the cardboard bin; and a fourth driving cylinder, which is transmission-connected to the suction cup and drives the suction cup to move up and down, and after absorbing the cardboard, places the cardboard on the cardboard pallet.

[0017] From the above, the cardboard at the bottom of the cardboard bin can be automatically adsorbed and placed on the cardboard pallet by the suction cup, so that the automatic loading of the cardboard can be realized to improve the production efficiency.

[0018] As a possible implementation of the first aspect, the conveying mechanism also includes: a baffle, which is vertically arranged at a position between the first conveying roller and the accumulation station; a fifth driving cylinder, which is transmission-connected to the baffle and drives the baffle to move upward to be exposed from above the first conveying roller, or to move downward to be hidden under the first conveying roller.

[0019] From above, by setting a baffle, the baffle is driven by the fifth driving cylinder to move up and down, so as to be exposed or hidden from above the first conveying roller. Thus, when the first conveying roller needs to convey materials to the accumulation station, the baffle can be hidden to facilitate the passage of materials. Alternatively, when it is not necessary to convey materials to the accumulation station, the baffle is exposed to block the materials to prevent excessive materials from being conveyed to the accumulation station.

[0020] As a possible implementation of the first aspect, the conveying mechanism also includes: a third conveying roller, which is arranged in the middle position of the first conveying roller; a limit member, which is arranged above the third conveying roller; a sixth driving cylinder, which is transmission-connected to the third conveying roller and drives the third conveying roller to move upward to clamp the material between the third conveying roller and the limit member, or move downward to be flush with the first conveying roller.

[0021] From the above, when it is necessary to stop the first conveyor roller from conveying materials, the third conveyor roller can be driven upward by the sixth drive cylinder to clamp the materials between the third conveyor roller and the limiter, thereby blocking the materials and preventing the first conveyor roller from conveying the materials. When it is necessary for the first conveyor roller to continue conveying materials, the third conveyor roller can be driven by the sixth drive cylinder to be flush with the first conveyor roller, so that the materials can pass through the first conveyor roller.

[0022] A second aspect of the present application provides a packaging device, comprising the accumulation device described in any one of the first aspect of the present application.

[0023] From the above, after the conveying mechanism conveys the material to the lifting member of the accumulation station through the first conveying roller, the lifting member and the material can be driven up or down by the first driving cylinder, thereby vacating the accumulation station. Then, the material can be conveyed to the accumulation station by the first conveying roller, so that another layer of material can be formed. In this way, the material can be automatically accumulated in layers instead of manually, thereby improving the packing efficiency and reducing safety hazards.

[0039] Below, in conjunction with the accompanying drawings, a possible embodiment of the accumulation device 10 in the present application is exemplarily described.

[0040] The present application provides an accumulation device 10, including a conveying mechanism 100 and an accumulation mechanism 200. The conveying mechanism 100 has a first conveying roller 110, and the end of the first conveying roller 110 is connected to an accumulation station. The first conveying roller 110 is used to convey materials 20 to the accumulation station. The accumulation mechanism 200 has a lifting member 220 and a first driving cylinder 230. The first driving cylinder 230 is connected to the lifting member 220 by transmission, and drives the lifting member 220 to rise and fall. The lifting member 220 is located at the accumulation station. After the first conveying roller 110 conveys a predetermined amount of material 20 to the lifting member 220, the first driving cylinder 230 drives the lifting member 220 to rise or fall. Accordingly, the first conveying roller 110 conveys the predetermined amount of material 20 to the bottom or top of the material 20 on the lifting member 220.

[0041] As described above, after the conveying mechanism 100 conveys the material 20 to the lifting member 220 of the accumulation station through the first conveying roller, the lifting member 220 and the material 20 can be driven to rise or fall through the first driving cylinder 230, thereby vacating the accumulation station. Then, the material 20 can be conveyed to the accumulation station by the first conveying roller, so that another layer of material 20 can be formed. In this way, the material 20 can be automatically accumulated in layers instead of manually, thereby improving the packing efficiency and reducing safety hazards.

[0042] In some embodiments, the lifting member 220 is a multi-layer structure, each layer is openly arranged on one side facing the first conveying roller 110, and when the first driving cylinder 230 drives the lifting member 220 to rise and fall so that each layer of the lifting member 220 is aligned with the first conveying roller 110, the conveying mechanism 100 drives the material 20 to enter each layer of the lifting member 220. Therefore, by setting the lifting member 220 into a multi-layer structure, after the first driving cylinder 230 drives each layer of the lifting member 220 to align with the first conveying roller 110, the material 20 can be conveniently conveyed to each layer of the lifting member 220 through the first conveying roller 110, so that the material 20 forms a multi-layer arrangement.

[0043] In some embodiments, the accumulation mechanism 200 further has a second conveyor roller 210, which is located at the accumulation station and connected to the end of the first conveyor roller 110, and is used to convey the material 20 provided by the first conveyor roller 110. The lifting member 220 includes a first mounting plate 221 and a supporting plate 222, the first mounting plate 221 is located below the second conveyor roller 210, and the first mounting plate 221 is connected to the first driving cylinder 230 by transmission, driving the mounting member to rise and fall. The supporting plate 222 is installed on the first mounting plate 221, and divides the space above the first mounting plate 221 into multiple layers in the vertical direction. The supporting plate 222 has multiple supporting arms on each layer, and the supporting arms extend in the horizontal direction and are respectively located between the conveying rollers of the second conveyor roller 210. Therefore, by setting the second conveyor roller 210 at the accumulation station, the material 20 provided by the first conveyor roller 110 can be conveyed. Thus, it is convenient to form multiple rows of materials 20 at the accumulation station, and improve the stability of the materials 20 when being transported at the accumulation station. In addition, by arranging multiple supporting arms between the conveying rollers of the second conveying roller 210, the supporting arms can pass through the second conveying roller 210 when the driving type of the first driving cylinder 230 rises and falls, thereby avoiding the impact between the second conveying roller 210 and the supporting arms.

[0044] In some embodiments, the accumulation device 10 further includes a pushing mechanism 300, which includes a pushing plate 310 and a transmission belt 320. The pushing plate 310 is arranged above the second conveying roller 210 and has a plurality of pushing arms, which extend downward and are respectively located between the supporting arms. The transmission belt 320 is arranged along the extension direction of the supporting arm, and is transmission-connected with the pushing plate 310 to drive the pushing plate 310 to move along the extension direction of the supporting arm. Thus, by setting the transmission belt 320 along the extension direction of the supporting arm, the pushing plate 310 is transmission-connected with the transmission belt 320, so that the pushing plate 310 can be driven to move along the extension direction of the supporting arm. By locating the pushing arm between the supporting arms, when the pushing plate 310 is driven to move along the extension direction of the supporting arm, the pushing arm can simultaneously push the materials 20 on the upper and lower layers of the supporting arm, thereby improving the packing efficiency.

[0045] In some embodiments, the lifting member 220 is in the shape of a plate, and the first driving cylinder 230 is used to drive the lifting member 220 to rise and be flush with the first conveyor roller 110 or to descend. The accumulation mechanism 200 also includes a pallet plate 240 and a second driving cylinder 250. Among them, the pallet plate 240 is horizontally arranged and is located at one side of the accumulation station. The second driving cylinder 250 is connected to the pallet plate 240 by transmission, and the lifting member 220 drives the pallet plate 240 to move to the end of the first conveyor roller 110 after the lifting member 220 descends. Therefore, after the first driving cylinder 230 drives the lifting member 220 to rise and be flush with the first conveyor roller 110, the first conveyor roller 110 can transport the material 20 to the lifting member 220 to form a first layer of material 20. After the first driving cylinder 230 drives the lifting member 220 to descend, the accumulation station can be vacated so that the second driving cylinder 250 can drive the inserting plate 240 to move to the end of the first conveying roller 110, and then the first conveying roller 110 conveys the material 20 to the inserting plate 240 to form a second layer of material 20.

[0046] In some embodiments, the accumulation device 10 further includes a cardboard bin mechanism 400, which is used to provide cardboard 30. The accumulation mechanism 200 further includes a cardboard support plate 260, a cardboard push plate 270 and a third drive cylinder 280. The cardboard support plate 260 is located at the other side of the accumulation station, and the cardboard 30 provided by the cardboard bin mechanism 400 is located on the cardboard support plate 260. The cardboard push plate 270 is located at a position where the cardboard support plate 260 is away from the accumulation station. The third drive cylinder 280 is connected to the cardboard push plate 270 by transmission, and drives the cardboard push plate 270 to push the cardboard 30 to the position of the accumulation station. Therefore, after the first drive cylinder 230 drives the lifting member 220 and the material 20 to descend, the cardboard push plate 270 can push the cardboard 30 provided by the cardboard bin mechanism 400 to the accumulation station. Therefore, a layer of cardboard 30 can be added between two layers of material 20, so that each layer of material 20 can be more stable after the accumulation of the material 20 is completed.

[0047] In some embodiments, the paperboard bin mechanism 400 includes a paperboard bin 410, a suction cup 420, and a fourth driving cylinder 430. The paperboard bin 410 is located above the paperboard pallet 260 and is used to store paperboards 30. The suction cup 420 is located below the paperboard bin 410 and is used to absorb the paperboards 30 in the paperboard bin 410 from the bottom of the paperboard bin 410. The fourth driving cylinder 430 is connected to the suction cup 420 in a transmission manner, and drives the suction cup 420 to move up and down, and after absorbing the paperboard 30, the paperboard 30 is placed on the paperboard pallet 260. In this way, the paperboard 30 at the bottom of the paperboard bin 410 can be automatically absorbed and placed on the paperboard pallet 260 by the suction cup 420, so that the automatic loading of the paperboard 30 can be realized to improve production efficiency.

[0048] In some embodiments, the conveying mechanism 100 further includes a baffle 120 and a fifth drive cylinder 130. The baffle 120 is vertically arranged between the first conveying roller 110 and the accumulation station. The fifth drive cylinder 130 is connected to the baffle 120 in a transmission manner, and drives the baffle 120 to move upward to be exposed from above the first conveying roller 110, or to move downward to be hidden below the first conveying roller 110. Thus, by setting the baffle 120, the baffle 120 is driven by the fifth drive cylinder 130 to move up and down, thereby being exposed or hidden from above the first conveying roller 110. Thus, when the first conveying roller 110 needs to convey the material 20 to the accumulation station, the baffle 120 can be hidden to facilitate the passage of the material 20. Alternatively, when the material 20 does not need to be conveyed to the accumulation station, the baffle 120 is exposed to block the material 20 to prevent excessive material 20 from being conveyed to the accumulation station.

[0049] In some embodiments, the conveying mechanism 100 further includes a third conveying roller 140, a stopper 150 and a sixth drive cylinder 160. The third conveying roller 140 is arranged at the middle position of the first conveying roller 110, and the stopper 150 is arranged above the third conveying roller 140. The sixth drive cylinder 160 is connected to the third conveying roller 140 by transmission, and drives the third conveying roller 140 to move upward to clamp the material 20 between the third conveying roller 140 and the stopper 150, or moves downward to be flush with the first conveying roller 110. Therefore, when it is necessary to prevent the first conveying roller 110 from conveying the material 20, the third conveying roller 140 can be driven by the sixth drive cylinder 160 to move upward to clamp the material 20 between the third conveying roller 140 and the stopper 150, so that the material 20 can be blocked and the first conveying roller 110 is prevented from conveying the material 20. When the first conveying roller 110 needs to continue conveying the material 20 , the third conveying roller 140 can be driven by the sixth driving cylinder 160 to be flush with the first conveying roller 110 , so that the material 20 can pass through the first conveying roller 110 .

[0050] The present application also provides a packaging device, including an accumulation device 10. The accumulation device 10 can be any possible implementation of the above-mentioned accumulation device 10, which will not be described in detail here.

[0051] The above content is an exemplary description of possible embodiments of the accumulating device 10 and the packaging equipment. Next, in conjunction with the accompanying drawings, the specific structure of the accumulating device 10 is described in detail in a specific embodiment.

[0052] Example 1

[0053] Figure 1 It is a schematic diagram of the left side orthographic projection structure of the accumulation device 10 in Example 1; Figure 2 FIG. 1 is a schematic diagram of the front side projection structure of the accumulation device 10 in the embodiment 1. Figure 1 , Figure 2 As shown, the accumulation device 10 in Embodiment 1 includes a conveying mechanism 100, an accumulation mechanism 200 and a pushing mechanism 300. The conveying mechanism 100 is used to convey the material 20 to the accumulation mechanism 200, the accumulation mechanism 200 is used to accumulate the material 20 conveyed by the conveying mechanism 100 in layers, and the pushing mechanism 300 is used to push the material 20 accumulated by the accumulation mechanism 200 to the next process.

[0054] like Figure 1 As shown, the conveying mechanism 100 includes a first conveying roller 110 horizontally arranged in the front-to-back direction. The front side of the front end of the first conveying roller 110 is an accumulation station. The first conveying roller 110 is used to convey the material 20 to the accumulation station. The material 20 can be transported in a single row or multiple rows (from the left side of the accumulation device 10, Figure 1 The rear of the material 20 is hidden by one or more materials 20. Figure 2 As shown, three rows of materials 20 are arranged in the left and right directions, and the materials 20 are transported to the accumulation station.

[0055] like Figure 1 As shown, the conveying mechanism 100 also includes a baffle 120 and a fifth drive cylinder 130. The baffle 120 is vertically arranged at a position between the first conveying roller 110 and the accumulation station. The fifth drive cylinder 130 is arranged at a lower position of the first conveying roller 110, and has a vertically arranged drive rod. The drive rod of the fifth drive cylinder 130 is fixedly installed with the baffle 120, and can drive the baffle 120 to be exposed from the upper surface of the first conveying roller 110, thereby blocking the material 20 conveyed by the first conveying roller 110. As a result, the material 20 can be accumulated in one or more rows at the front end position of the first conveying roller 110 under the obstruction of the baffle 120 (seen from the left side of the accumulation device 10, Figure 1The fifth drive cylinder 130 can also drive the baffle 120 to be hidden under the first conveying roller 110, so that the materials 20 accumulated at the front end of the first conveying roller 110 can be transported to the accumulation station together.

[0056] like Figure 1 As shown, the conveying mechanism 100 also includes a third conveying roller 140, a stopper 150 and a sixth drive cylinder 160. The third conveying roller 140 is arranged in the middle position of the first conveying roller 110 and is flush with the first conveying roller 110. Specifically, the distance between the front end of the third conveying roller 140 and the first conveying roller 110 is greater than or equal to the size of the material 20 that needs to be transported to the accumulation station together. The stopper 150 is arranged directly above the third conveying roller 140, and the sixth drive cylinder 160 is arranged directly below the third conveying roller 140. The drive rod of the sixth drive cylinder 160 is vertically arranged and fixedly connected to the third conveying roller 140, and can drive the third conveying roller 140 to move up and down. The length of the third conveyor roller 140 is adapted to the size of the material 20. When the material 20 is conveyed to the third conveyor roller 140, the sixth drive cylinder 160 can drive the third conveyor roller 140 to rise, and clamp the material 20 between the third conveyor roller 140 and the stopper 150. Thus, after the square array of materials 20 on the first conveyor roller 110 in front of the third conveyor roller 140 reaches a predetermined number of columns (the number of columns of the square array of materials 20), the materials 20 on the first conveyor roller 110 behind the third conveyor roller 140 can be blocked from being conveyed forward.

[0057] like Figure 1 As shown, the conveying mechanism 100 further includes a detection optical fiber 170, which is disposed above the first conveying roller 110 and horizontally extends backward from the front end of the first conveying roller 110. The detection optical fiber 170 is used to detect the number of columns of the material 20 on the first conveying roller 110 in front of the third conveying roller 140, and the fifth driving cylinder 130 and the sixth driving cylinder 160 can be controlled according to the detection result of the detection optical fiber 170.

[0058] When the detection optical fiber 170 detects that the number of columns of the material 20 on the first conveyor roller 110 in front of the third conveyor roller 140 reaches a predetermined number, and detects that the next material 20 reaches the third conveyor roller 140, the sixth driving cylinder 160 is controlled to drive the third conveyor roller 140 to rise, clamp the material 20 between the third conveyor roller 140 and the stopper 150, and prevent the material 20 on the first conveyor roller 110 behind the third conveyor roller 140 from being transported forward. At the same time, the fifth driving cylinder 130 is controlled to drive the baffle 120 to descend below the first conveyor roller 110, so that the material 20 accumulated on the first conveyor roller 110 in front of the third conveyor roller 140 is transported forward to the accumulation station.

[0059] When the detection optical fiber 170 detects that the material 20 on the first conveyor roller 110 in front of the third conveyor roller 140 is less than the predetermined number of columns or is 0, the sixth drive cylinder 160 is controlled to drive the third conveyor roller 140 to descend to a position flush with the first conveyor roller 110, so that the third conveyor roller 140 and the material 20 on the first conveyor roller 110 behind it are conveyed forward. At the same time, the fifth drive cylinder 130 is controlled to drive the baffle 120 to rise to the upper position of the first conveyor roller 110, to block the material 20 conveyed to the front end of the first conveyor roller 110, and to accumulate the material 20 again.

[0060] like Figure 1 , Figure 2 As shown, the accumulation mechanism 200 includes a second conveyor roller 210, a lifting member 220 and a first drive cylinder 230. The second conveyor roller 210 is arranged at the front end of the first conveyor roller 110, is in the accumulation station, and is connected to the first conveyor roller 110. The second conveyor roller 210 can stably convey the material 20 provided by the first conveyor roller 110 to the predetermined position of the accumulation station. The first drive cylinder 230 is arranged below the second conveyor roller 210 and has a vertically arranged drive rod. The lifting member 220 is fixedly mounted on the drive rod of the first drive cylinder 230 and can move up and down under the drive of the first drive cylinder 230.

[0061] like Figure 1 , Figure 2As shown, the lifting member 220 includes a first mounting plate 221 and a supporting plate 222. The first mounting plate 221 is in the shape of a rectangular flat plate, horizontally arranged below the second conveying roller 210, and fixedly connected to the driving rod of the first driving cylinder 230. The supporting plate 222 has a plurality of supporting arms, which are arranged between the conveying rollers of the second conveying roller 210 and staggered with the conveying rollers of the second conveying roller 210, so that the supporting arms can pass through the second conveying roller 210 up and down. Specifically, each supporting arm extends upward from the space between the corresponding two conveying rollers to a certain height (greater than the height of the material 20) at the right edge of the accumulation station, and then extends horizontally to the left, forming a horizontal fork shape with other supporting arms, forming a plane for placing the material 20. The supporting arms form a multi-layer structure above the first mounting plate 221, dividing the space above the first mounting plate 221 into two layers. Thus, after the first driving cylinder 230 drives the lifting member 220 to descend to the bottom of the second conveyor roller 210, the fifth driving cylinder 130 drives the baffle 120 to descend to the bottom of the first conveyor roller 110, so that the material 20 accumulated on the first conveyor roller 110 is transported forward to the second conveyor roller 210 of the accumulation station. Then the first driving cylinder 230 drives the lifting member 220 to rise, and the supporting arm lifts the material 20 on the second conveyor roller 210 to clear the second conveyor roller 210, and the first conveyor roller 110 transports the accumulated material 20 again to the second conveyor roller 210 to form a second layer.

[0062] In some embodiments, the support plate 222 may also be provided with multiple layers of support arms in the up and down directions, so that the accumulation device 10 can not only form two layers of material 20 at the accumulation station, but also form three, four or more layers of material 20.

[0063] like Figure 1 , Figure 2 As shown, the pushing mechanism 300 includes a pushing plate 310, a transmission belt 320, a second mounting plate 330 and a seventh driving cylinder 340. The transmission belt 320 is arranged above the accumulation station and is arranged horizontally in the left and right directions. The second mounting plate 330 is fixedly arranged on the transmission belt 320 and can move left and right under the drive of the transmission belt 320. There are two seventh driving cylinders 340, which are respectively arranged at the left and right ends of the lower surface of the second mounting plate 330. The two seventh driving cylinders 340 are arranged back to back and have driving rods extending to the left and right respectively. There are two pushing plates 310, which are respectively fixed on the driving rods of the two seventh driving cylinders 340. The pushing plate 310 has a plurality of pushing arms, which extend downward to form a fork shape and are respectively located between the supporting arms and staggered with the supporting arms, so that when the supporting arms move up and down under the drive of the first driving cylinder 230, they avoid interference with the pushing arms.

[0064] The two pusher plates 310 are arranged in parallel, and the distance between the two pusher plates 310 in the left-right direction is greater than the size of the three rows of materials 20, so that the first conveyor roller 110 can convey the three rows of materials 20 to between the two pusher plates 310. After the two layers of materials 20 are accumulated at the accumulation station, the seventh drive cylinder 340 drives the two pusher plates 310 to move closer, so that the materials 20 between the two pusher plates 310 can be pushed closer, making the accumulated materials 20 more compact. Then, the transmission belt 320 drives the pusher plates 310 to move from right to left, so that the materials 20 leave the accumulation station, and the upper layer of materials 20 fall on the bottom layer of materials 20, and the materials 20 are pushed into the next process.

[0065] Example 2

Figure 3-Figure 7 As shown, the accumulation mechanism 200 in Example 2 has a different structure from the accumulation mechanism 200 in Example 1. The accumulation device 10 in Example 2 further includes a cardboard bin mechanism 400, which is used to provide cardboard 30 to the accumulation mechanism 200.

[0067] In Example 2, the accumulation mechanism 200 includes a lifting member 220, a first drive cylinder 230, a support plate 240 and a second drive cylinder 250. The lifting member 220 is in the shape of a flat plate and is arranged at a position corresponding to the accumulation station. The first drive cylinder 230 is arranged below the accumulation station, and the drive rod of the first drive cylinder 230 is arranged vertically and fixedly connected to the lifting member 220. The lifting member 220 can rise to a position flush with the first conveyor roller 110 under the drive of the first drive cylinder 230, and connect with the first conveyor roller 110, so that the first conveyor roller 110 can transport the accumulated material 20 to the lifting member 220 of the accumulation station to form a first layer of material 20.

[0068] like Figure 3-Figure 5As shown, the second drive cylinder 250 is arranged at the right side of the accumulation station and has a drive rod extending horizontally in the left and right directions. The inserting plate 240 is arranged horizontally at the right side of the accumulation station, is on the same horizontal plane as the first conveying roller 110, and is fixedly connected to the drive rod of the second drive cylinder 250. After the first drive cylinder 230 drives the lifting member 220 and the material 20 to descend below the plane where the first conveying roller 110 is located, the second drive cylinder 250 drives the inserting plate 240 to move horizontally to the accumulation station and connect with the front end of the first conveying roller 110. The first conveying roller 110 can transport the accumulated material 20 to the inserting plate 240 of the accumulation station to form a second layer of material 20.

[0069] like Figure 3-Figure 5 As shown, the accumulation mechanism 200 also includes a cardboard support plate 260, a cardboard push plate 270 and a third drive cylinder 280. The cardboard support plate 260 is horizontally arranged at the left side of the accumulation station, slightly lower than the inserting support plate 240. The cardboard push plate 270 and the third drive cylinder 280 are located at a side of the cardboard support plate 260 away from the accumulation station. The third drive cylinder 280 has a drive rod extending in the left and right directions, and the cardboard push plate 270 is fixedly mounted on the drive rod of the third drive cylinder 280. After the cardboard 30 provided by the cardboard bin mechanism 400 is placed on the cardboard support plate 260, the third drive cylinder 280 can drive the cardboard push plate 270 to push the cardboard 30 on the cardboard support plate 260 toward the accumulation station, so that the cardboard 30 falls on the upper surface of the material 20 on the lifting member 220.

[0070] like Figure 6 , Figure 7As shown, the accumulation mechanism 200 also includes a limit plate 291 and an eighth drive cylinder 292. Two limit plates 291 are provided, which are respectively arranged vertically at the left and right sides of the accumulation station. After the first conveying roller 110 conveys the accumulated material 20 to the accumulation station, the material 20 is located between the two limit plates 291. Two eighth drive cylinders 292 are provided, which are respectively located at the outer positions of the two limit plates 291. The eighth drive cylinder 292 has a drive rod extending in the left and right directions. The drive cylinders of the two eighth drive cylinders 292 are respectively fixedly connected to the corresponding limit plates 291, and can drive the two limit plates 291 to move closer to or away from each other. Therefore, after the first conveying roller 110 conveys the accumulated material 20 to the accumulation station, the eighth drive cylinder 292 drives the limit plates 291 to move closer, thereby pushing the materials 20 in the accumulation station to move closer to each other, thereby making the materials 20 more compact. In addition, after the first conveyor roller 110 conveys the accumulated material 20 to the pallet 240 of the accumulation station, when the third driving cylinder 280 drives the pallet 240 to leave the accumulation station and return to the right side of the accumulation station, the limit plate 291 can limit the material 20 on the accumulation station to prevent the material 20 from moving to the right out of the accumulation station with the pallet 240, so that the material 20 can fall on the cardboard 30 under the action of gravity, thereby forming multiple layers of the material 20 on the lifting member 220.

[0071] like Figure 3-Figure 5 As shown, the cardboard bin mechanism 400 includes a cardboard bin 410, a suction cup 420 and a fourth drive cylinder 430. The cardboard bin 410 is located above the cardboard support plate 260 and is used to store cardboards 30. The cardboards 30 are horizontally arranged in the cardboard bin 410 and stacked in the vertical direction. The bottom of the cardboard bin 410 has an opening, and the suction cup 420 is located below the cardboard bin 410. The suction cup 420 can be connected to the cardboard 30 at the bottom of the cardboard bin 410 by suction using negative pressure. The fourth drive cylinder 430 is arranged below the cardboard support plate 260 and has a vertically extending drive rod. The drive rod of the fourth drive cylinder 430 is fixedly connected to the suction cup 420 and can drive the suction cup 420 to move up and down. Thus, the fourth driving cylinder 430 can drive the suction cup 420 to move upward, and connect with the cardboard 30 at the bottom of the cardboard bin 410 by suction, and then the fourth driving cylinder 430 can drive the suction cup 420 and the cardboard 30 sucked by it to move downward, so that the cardboard 30 is pulled out from the opening at the bottom of the cardboard bin 410, and the cardboard 30 is placed on the cardboard support plate 260. Finally, the suction cup 420 is separated from the cardboard 30, and the fourth driving cylinder 430 drives the suction cup 420 to continue to move downward, so that when the cardboard push plate 270 pushes the cardboard 30 on the cardboard support plate 260 to move to the right, the suction cup 420 can be prevented from obstructing the cardboard push plate 270.
