Description

Technical Field

[0001] This utility model relates to the field of stamping technology, and specifically to a material accumulation device. Background Technology

[0002] In the stamping production process, many material accumulators are needed. For example, the utility model patent CN204584107U, entitled "A Material Accumulator Applied to Sheet Stamping," includes a base support, a worktable on the base support, workstations on the worktable, a lifting module on the lower side of the base support, and an operating platform on the upper side of the base support. Sheet separation modules and a first detection switch are distributed on the front, back, left, and right sides of the inner side of the operating platform. Vertical stop positioning plates are set around the workstations on the worktable. The sheet separation module includes a magnet at the upper end and a guide rod at the lower end. This material accumulator, designed for sheet separation processing, achieves accurate and efficient separation of sheet materials through reasonable structural improvements, especially through the cooperation of the sheet separation module and the first detection switch on the operating platform. This prepares the material for the robot to accurately grasp the sheet material and for subsequent stamping work, thus improving work efficiency.

[0003] However, during the process of collecting the material sheets, the surface of the material sheets is not perfectly flat, resulting in gaps between the material sheets when they are stacked from top to bottom into the material rack. This leads to uneven stacking of the material sheets, causing them to tilt and fall during the lifting process, resulting in scratches on the surface of the material sheets and rendering them unusable. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a material accumulation device to solve the technical problem in the prior art that the material sheets are not stacked neatly during the collection process, which causes the material sheets to tilt and fall during the feeding process, resulting in scratches and scrapping of the material sheet surface.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a material accumulation device, including a stacking assembly and a material accumulation rack. The stacking assembly includes an operating table, several limiting rods, several straightening rods, a lifting component, and several first driving components. The top of the operating table has a material drop opening. Each of the limiting rods and each of the straightening rods is evenly distributed around the circumference of the material drop opening and forms a material drop channel. The lifting component is located in the material drop channel and is used to support the material pieces falling from the material drop channel. Each of the first driving components is tractively connected to each of the straightening rods. The first driving component is used to drive the straightening rod to collide with the material pieces on the lifting component. The material accumulation rack is located directly below the material drop channel and is used to receive the stack of straightened material pieces on the lifting component.

[0006] In some embodiments, a first conveyor line is also included, the bottom of the operating table is fixedly connected to the top of the first conveyor line, and a plurality of the material collection racks are provided. The first conveyor line is used to drive each of the material collection racks into the operating table one by one to pick up materials.

[0007] In some embodiments, the material accumulator includes a flat plate, a plurality of baffles and a plurality of guide wheels. Each baffle is mounted on the top of the flat plate, the flat plate is slidably connected to the first conveyor line, and each guide wheel is mounted around the flat plate and slidably connected to the side wall of the first conveyor line.

[0008] In some embodiments, each of the flat plates is provided with a lifting hole, the first conveyor line is provided with a receiving hole, and the lifting member includes a second driving member and a material support plate. The second driving member is installed at the bottom of the first conveyor line and is used to drive the material support plate to pass through the receiving hole and the lifting hole from bottom to top and then enter the dropping channel.

[0009] In some embodiments, a first detection switch is provided on the top of the operating table. The first detection switch is electrically connected to the first driving member and causes the corrective rod to autonomously collide with the material sheet on the material support plate.

[0010] In some embodiments, a second detection switch is provided on the top of the operating table. The second detection switch is electrically connected to the second drive component, so that the material support plate will automatically descend by the thickness of one material piece each time it receives a material piece.

[0011] In some embodiments, a third detection switch is provided on one side of the operating table. The third detection switch is electrically connected to the second drive unit and enables the corrected material stack on the material support plate to be autonomously transferred to the material accumulation rack.

[0012] In some embodiments, the palletizing assembly further includes a plurality of receiving components, each of which is evenly distributed around the circumference of the discharge port. Each receiving component includes a receiving plate and a third driving component. The third driving component is mounted on the top of the operating table and is used to drive the receiving plate to extend toward the center of the discharge port and temporarily support the falling material.

[0013] In some embodiments, the receiving plate is provided with a clearance groove at one end facing the center of the discharge port.

[0014] In some embodiments, a second conveyor line is also included, wherein each of the correcting rods is located between each of the limiting rods and the second conveyor line, and the correcting rods, the second conveyor line and the limiting rods increase in height sequentially.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0019] To address the technical problem that uneven stacking of material sheets during the initial collection process leads to tilting and falling during the later feeding process, resulting in scratches and scrapping of the material sheets, this utility model provides a material accumulation device that ensures neat stacking of material sheets during the initial collection process, thus preventing tilting and falling of the material sheets during the later feeding process.

[0020] It should be noted that the material accumulation device described in this utility model is used for, but not limited to, stamping, etc. For ease of explanation, this utility model only uses the application of a material accumulation device in stamping as an example for explanation. The principle of a material accumulation device applied in other environments is essentially the same as the principle applied in stamping, and will not be described in detail here.

[0021] Please see Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the structure of a material accumulation device according to an embodiment of the present invention. The material accumulation device includes a stacking assembly 1 and a material accumulation rack 2. The stacking assembly 1 includes an operating table 11, a plurality of limiting rods 12, a plurality of correcting rods 13, a lifting component 14, and a plurality of first driving components 15. A material drop port 111 is provided on the top of the operating table 11. Each limiting rod 12 and each correcting rod 13 is evenly distributed around the circumference of the material drop port 111 and forms a material drop channel 16. The lifting component 14 is located in the material drop channel 16 and is used to support the material pieces falling from the material drop channel 16. Each first driving component 15 is connected to each correcting rod 13 in a transmission manner. The first driving component 15 is used to drive the correcting rod 13 to collide with the material pieces on the lifting component 14. The material accumulation rack 2 is located directly below the material drop channel 16 and is used to receive the stack of corrected material pieces on the lifting component 14.

[0022] In this embodiment, the material drop port 111, the limiting rod 12, and the straightening rod 13 form a stacking structure and a straightening structure for the material sheets. This allows the material sheets to be stacked and straightened simultaneously after falling into the material drop channel 16, so that the material sheets are pressed together and form an air pressure difference, which improves the neatness and stability of the material sheet stack. Furthermore, the lifting component 14 and the material accumulation rack 2 allow the straightened material sheet stack to be transported with the material accumulation rack 2, which makes the material sheets more stable during the subsequent die feeding process and avoids the material sheets from tipping over and falling.

[0023] Furthermore, each limit rod 12 has a connecting block at its bottom, and the connecting block is fixedly connected to the top of the operating table 11 by screws. The top of the operating table 11 has multiple sets of threaded holes, and the threaded holes are arranged in the direction of the material drop port 111. The limit rod 12 can be adapted to different sizes of material pieces by selecting to connect to the threaded holes at different positions.

[0024] In one embodiment, a first conveyor line 3 is also included. The bottom of the operating table 11 is fixedly connected to the top of the first conveyor line 3, and a plurality of material collection racks 2 are provided. The first conveyor line 3 is used to drive each material collection rack 2 into the operating table 11 one by one to pick up materials.

[0025] In this embodiment, the first conveyor line 3 adopts a roller conveyor, and the first conveyor line 3 is equipped with two sensors. One sensor is used to detect whether the material rack 2 has moved to a preset position, and the other sensor is used to detect whether the material rack 2 is full. When an empty material rack 2 moves to the preset position between the operating table 11 and the first conveyor line 3, one of the sensors feeds back to the first conveyor line 3 and causes the first conveyor line 3 to stop. When the material rack 2 is full, the other sensor feeds back to the first conveyor line 3 and causes the first conveyor line 3 to start, and so on.

[0026] In one embodiment, the material accumulator 2 includes a flat plate 21, a plurality of baffles 22 and a plurality of guide wheels 23. Each baffle 22 is mounted on the top of the flat plate 21, the flat plate 21 is slidably connected to the first conveyor line 3, and each guide wheel 23 is mounted around the flat plate 21 and slidably connected to the side wall of the first conveyor line 3.

[0027] In this embodiment, each baffle 22 is used to block the material pile and prevent it from tipping over during transportation, while the guide wheel 23 is used to reduce the friction between the plate 21 and the first conveyor line 3, so that the plate 21 moves more smoothly.

[0028] In one embodiment, each plate 21 is provided with a lifting hole 211, the first conveyor line 3 is provided with a receiving hole 31, and the lifting component 14 includes a second driving component 141 and a material support plate 142. The second driving component 141 is installed at the bottom of the first conveyor line 3 and is used to drive the material support plate 142 to pass through the receiving hole 31 and the lifting hole 211 from bottom to top and then enter the dropping channel 16.

[0029] In this embodiment, when any lifting hole 211 is located directly above the receiving hole 31, the second driving member 141 can drive the material support plate 142 to pass through the receiving hole 31 and the lifting hole 211 from bottom to top and then enter the material drop channel 16; after the material support plate 142 transfers the material sheet to the plate 21, in order not to affect the movement of the material accumulation rack 2, the material support plate 142 is temporarily hidden in the receiving hole 31.

[0030] Furthermore, a connecting block is fixedly connected to the bottom of the stop bar 22. The connecting block is fixedly connected to the plate 21 by screws. The plate 21 has multiple threaded holes, and the threaded holes are arranged in the direction of the lifting hole 211, so that the stop bar 22 can be used for different sizes of material pieces by selecting to connect different threaded holes.

[0031] In one embodiment, the top of the operating table 11 is provided with a first detection switch 151, which is electrically connected to the first driving member 15 and causes the correcting rod 13 to autonomously collide with the material sheet on the material support plate 142.

[0032] In this embodiment, the material pieces are corrected one by one, which makes it easier to improve the neatness of the material piece stack.

[0033] In one embodiment, a second detection switch 143 is provided on the top of the operating table 11. The second detection switch 143 is electrically connected to the second drive member 141 and causes the material support plate 142 to automatically descend by the thickness of one material piece each time it receives a material piece.

[0034] In this embodiment, the second detection switch 143 of the channel is set to facilitate the real-time correction of the correction rod 13. During the stacking process, no matter how many pieces are stacked, the top surface of the stack of pieces is always located on the same horizontal plane, and this horizontal plane is always located between each limit rod 12 and each correction rod 13, thus avoiding the problem that the correction rod 13 cannot be corrected as the stack of pieces increases.

[0035] In one embodiment, a third detection switch 144 is provided on one side of the operating table 11. The third detection switch 144 is electrically connected to the second drive member 141 and enables the corrected material stack on the material support plate 142 to be autonomously transferred to the material accumulation rack 2.

[0036] In this embodiment, under the action of the second detection switch 143, as the material support plate 142 gradually descends, when the third detection switch 144 detects the bottom piece of material, it indicates that the number of material pieces stacked has reached the standard and needs to be transferred to the stacking rack 2 for easy transportation.

[0037] In one embodiment, the palletizing assembly 1 further includes a plurality of receiving components 17, each receiving component 17 being evenly distributed around the circumference of the discharge port 111. Each receiving component 17 includes a receiving plate 171 and a third driving component 172. The third driving component 172 is mounted on the top of the operating table 11 and is used to drive the receiving plate 171 to extend toward the center of the discharge port 111 and temporarily support the falling material.

[0038] In this embodiment, the function of the receiving component 17 is to achieve continuous non-stop processing. When there is no material accumulation rack 2 directly below the material drop channel 16, each third driving component 172 drives each receiving plate 171 to extend simultaneously, so that the material can temporarily fall onto the receiving plate 171 without stopping the machine to wait for the material, which effectively improves the processing efficiency.

[0039] It should be noted that the third detection switch 144 is also electrically connected to the third drive unit 172. When the third detection switch 144 detects the material sheet, the second drive unit 141 and the third drive unit 172 are started synchronously. The second drive unit 141 drives the material support plate 142 to descend, so that the corrected material sheet is transferred to the material accumulation rack 2. At the same time, the third drive unit 172 drives the receiving plate 171 to extend and is used to temporarily support the fallen material sheet.

[0040] In one embodiment, the receiving plate 171 is provided with a clearance groove 1711 at the end facing the center of the discharge port 111.

[0041] In this embodiment, the relief groove 1711 is provided to facilitate the change of the support structure of the material sheet, which is changed from the original receiving plate 171 to the support of the material support plate 142. The material support plate 142 is adapted to the relief groove 1711, passes through the relief groove 1711 from bottom to top and supports the material sheet on the receiving plate 171, and the receiving plate 171 retracts.

[0042] In one embodiment, a second conveyor line 4 is also included, with each correcting rod 13 located between each limiting rod 12 and the second conveyor line 4, and each correcting rod 13, the second conveyor line 4 and each limiting rod 12 increasing in height sequentially.

[0043] In this embodiment, the orientation of each straightening rod 13, the second conveyor line 4 and each limiting rod 12 is arranged so that the material falling from the second conveyor line 4 can just jump over the straightening rod 13 and collide with the limiting rod 12 before falling smoothly into the material drop channel 16.

[0044] Furthermore, the second conveyor line 4 can be made using a conventional belt conveyor, which is less expensive than robotic feeding.

[0045] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail below: Step ① Move a material collection rack 2 between the material drop port 111 and the receiving hole 31 via the first conveyor line 3, so that the second driving member 141 can drive the material support plate 142 to pass through the receiving hole 31 and the lifting hole 211 in sequence and enter the material drop channel 16. Step ② The second conveyor line 4 conveys the stamped sheet one by one towards the discharge port 111. After each sheet jumps over the straightening rod 13, it falls onto the support plate 142 along the discharge channel 16. Each time a sheet falls, it will be detected by the first detection switch 151 and fed back to the first driving component 15, so that the first driving component 15 drives the straightening rod 13 to repeatedly collide with the sheet pile, so that the sheet pile is straightened. Step 3 When the material pieces accumulate to the preset height, they will be detected by the second detection switch 143 and fed back to the second drive unit 141. This will cause the second drive unit 141 to drive the material support plate 142 to drop by the thickness of one material piece for each subsequent material piece to fall, so that each subsequent material piece is located on the same horizontal plane, which is convenient for correction. Step 4: When the material support plate 142 descends to the preset height, the third detection switch 144 will detect the bottom piece of the material pile and feed back to the second drive unit 141 and the third drive unit 172. The second drive unit 141 will drive the material support plate 142 to transfer the corrected material pile to the material collection rack 2. The material support plate 142 will be hidden in the receiving hole 31. At the same time, the third drive unit 172 will drive the receiving plate 171 to extend and temporarily support the subsequent material pieces. Step 5: The first conveyor line 3 drives the fully loaded material rack 2 to the preset position, and at the same time, conveys the next empty material rack 2 to the position of the previous material rack 2. Step 6: The second driving component 141 drives the material support plate 142 to pass through the receiving hole 31, the lifting hole 211 and the clearance groove 1711 in sequence, and then supports the material stack on the receiving plate 171. At the same time, the third driving component 172 drives the receiving plate 171 to retract. Then, the process is repeated from step 1 above. The entire operation process does not require manual labor and does not require the first conveyor line 3 to be stopped, which improves the processing efficiency. At the same time, stacking and straightening are carried out simultaneously, which improves the stability of the material stack and avoids the problem of the material stack tipping and falling during the subsequent pressing process.

[0046] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
