A drawing collection and arrangement device

Abstract

The present invention relates to the technical field of drawing organization, and discloses a drawing collection and organization device, comprising a placement box for holding miscellaneous drawings and a collection box for holding drawings transferred from the placement box. The device also includes a suction cup that is driven to rotate by a drive mechanism. The placement box is elastically and slidably mounted on a support frame. The rotation of the suction cup causes the placement box to elastically slide downward during its compression and adsorption of the top drawing in the placement box, allowing the suction cup to move the top drawing away from the placement box and toward the collection box. The present invention utilizes the suction force of the suction cup to adsorb only the top drawing at a time, so that when the suction cup is offset from the placement box, only one drawing from the top drawing is removed from the placement box, ensuring that only one drawing is transferred each time.

Description

Technical Field

[0001] The present invention relates to the technical field of drawing arrangement, and in particular to a drawing collection and arrangement device. Background Art

[0002] In the entire process of visual communication design, drawings are constantly used. A large number of drawings are piled up in the office area in a disorderly manner, affecting work. Therefore, they need to be collected and organized into standardized drawing piles to avoid disorderly stacking of drawings. However, collecting and organizing drawings usually takes up a lot of working time. In order to replace manual collection and organization of drawings and save working time, special drawing collection and organization devices have also appeared in the prior art.

[0003] For example, the Chinese invention patent with application number CN201911066716.0 and authorization announcement number CN110775686B, entitled “A visual communication design drawing collection device”, discloses a drawing sorting box, a drawing storage box and a drive box. The output shaft end of the driving motor drives the driving gear, the axial drive roller and the radial drive disk to rotate together. The rotation of the axial drive roller causes the axial drive shaft to reciprocate in the axial direction, so that the limit plate drives the radial drive shaft and the conveying device to perform axial linkage along the length direction of the positioning tube, thereby achieving the purpose of conveying the drawings in the drawing sorting box to the drive box; the radial drive The rotation of the disk drives the positioning tube to rotate circumferentially, thereby driving the transmission box to rotate. During the rotation of the transmission box, the roller moves from the inner side of the arc-shaped guide plate to the top plate. Since the lower bottom surface of the top plate is an outward convex arc structure, the transmission shaft begins to compress the spring to drive the rubber wheel to gradually contact the drawings in the drawing sorting box. When the drawings in the drawing sorting box enter the driving box, the driving connecting rod starts to drive the conveyor shaft roller downward to contact the drawings entering the driving box, and the rotation of the driving gear drives the entire conveyor shaft roller to rotate. As the conveyor shaft roller rotates, the drawings in the driving box enter the drawing storage box, thereby realizing the collection and organization of the drawings.

[0004] The drawing collection device provided by the above invention patent can replace manual work in collecting and arranging drawings, but its disadvantages are: from the description and drawings of the above patent, it can be seen without a doubt that in the process of arranging drawings, when transferring drawings in the drawing arrangement box, the drawings are pressed down by the rubber wheel to generate friction between the rubber wheel and the drawings on the top layer, and then the drawings are driven to move to the drive box by the movement of the rubber wheel. Although the downward pressure of the rubber wheel can generate friction between it and the drawings on the top layer, it will also increase the friction between the drawings on the top layer and the drawings below it. Therefore, when the rubber wheel moves, not only will the friction between the drawings on the top layer and the drawings below it increase, but also the friction between the drawings on the top layer and the drawings below it will increase. The top layer of drawings in the drawing sorting box is transferred to the drive box, and at the same time, one or more drawings below the top layer are transferred to the drive box together, so that the number of drawings transferred to the drive box each time is not uniform, because the drawings in the drawing sorting box are messy. When multiple drawings are transferred to the drive box at the same time, the multiple drawings will still be in a messy pile-up state, and it is impossible to achieve unified and orderly arrangement of the drawings. It can be seen that in the process of drawing collection and arrangement, how to transfer only one drawing each time is crucial, and the above patent obviously cannot achieve the goal of transferring only one drawing each time. Summary of the Invention

[0005] The purpose of the present invention is to provide a drawing collection and arrangement device to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: a drawing collection and organization device, comprising a placement box for holding messy drawings and a collection box for holding drawings transferred from the placement box, and also comprising a suction cup driven to rotate by a driving mechanism, wherein the placement box is elastically slidably arranged on a support frame, and the rotation of the suction cup causes it to squeeze and absorb the top layer of drawings in the placement box, thereby driving the placement box to elastically slide down so that the suction cup drives the top layer of drawings to be offset from the placement box and then transferred toward the collection box.

[0007] In the above-mentioned drawing collection and sorting device, the driving mechanism is connected to the suction cup through an inflatable piece, the suction cup is sealed and installed on the vent of the inflatable piece, the suction cup is connected to the vent, and the inflatable piece drives the gas to flow into the suction cup to separate the drawing from the suction cup.

[0008] The above-mentioned drawing collection and organization device, the inflatable part includes a ventilation tube with one end closed and the other end open, the open end of the ventilation tube is a vent, the ventilation tube is fixedly provided with a branch pipe connected to it, the dynamic seal in the branch pipe is provided with an action rod with one end extending to the outside thereof, and a first return spring is installed between the action rod and the branch pipe.

[0009] In the above-mentioned drawing collection and organization device, the action rod includes a rod body and a piston fixedly connected, the diameter of the piston is larger than the diameter of the rod body, the piston dynamic seal is arranged in the branch pipe, and the end of the free end of the branch pipe is fixedly installed with a limiting ring for the rod body to slide through. In the initial state, the piston abuts against the limiting ring.

[0010] In the above-mentioned drawing collection and sorting device, an extension cross bar is fixedly installed at the free end of the rod body, and a blocking plate that abuts and cooperates with the extension cross bar is elastically rotatably provided on the support frame. In the process of the suction cup driving the top layer of drawings to transfer toward the collection box, the extension cross bar abuts against the blocking plate to push the piston to slide toward the inside of the branch pipe, driving the gas to flow into the suction cup, so that the drawings are separated from the suction cup and fall into the collection box.

[0011] In the above-mentioned drawing collection and sorting device, there are two blocking plates, which are respectively located on both sides of the collection box in the width direction. After the piston slides to the extreme position inside the branch pipe, the cross bar pushes the two blocking plates to rotate elastically so that the inflatable part passes over the blocking plates.

[0012] The above-mentioned drawing collection and sorting device, the collection box includes an L-shaped bottom plate and two side plates arranged opposite to each other, the two side plates are slidably connected to the L-shaped bottom plate, the two blocking plates are transmission-connected to the two side plates in a one-to-one correspondence, and the two blocking plates are driven by the cross bar to slide the two side plates toward the L-shaped bottom plate so that the two side plates push the drawings to the center.

[0013] In the above-mentioned drawing collecting and organizing device, the width of the L-shaped bottom plate is smaller than the width of the drawing.

[0014] In the above-mentioned drawing collecting and arranging device, when the suction cup abuts against the top drawing, the suction cup is close to the end of the placement box facing the inflatable member.

[0015] In the above-mentioned drawing collection and sorting device, the bottom height of the action rod is not higher than the bottom height of the inner cavity of the placement box, so that the action rod blocks the drawings in the placement box, preventing the suction cup from causing the drawings below the top layer to slip out of the placement box during the process of driving the top layer drawings to be offset from the placement box.

[0016] In the above technical solution, the present invention provides a drawing collection and sorting device, which can adsorb the drawings on the top layer in the placement box by rotating the suction cup and utilizing the downward extrusion force generated when the suction cup rotates, and the placement box is elastically slidable, so that under the action of the rotational force of the suction cup, the placement box can be pushed to slide elastically downward. During the sliding of the placement box, the suction cup will drive the top layer drawings and the placement box to move relative to each other until the suction cup and the placement box are offset. After the offset, the suction cup drives the top layer drawings to be transferred toward the collection box, and then the top layer drawings are transferred to the collection box for collection and sorting. Compared with the existing technology, the adsorption force of the suction cup is utilized to make it possible to adsorb only the drawings on the top layer at a time, so that when the suction cup and the placement box are offset, only one drawing on the top layer is moved out of the placement box, and only one drawing is transferred each time the drawings are transferred, which can effectively solve the shortcomings of the existing technology.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-9 As shown, an embodiment of the present invention provides a drawing collection and organization device, comprising a placement box 2 for holding messy drawings and a collection box 3 for holding drawings transferred from the placement box 2, and also comprising a suction cup 6 driven to rotate by a driving mechanism. The placement box 2 is elastically slidably arranged on the support frame 1. The rotation of the suction cup 6 causes it to squeeze and absorb the top layer of drawings in the placement box 2, thereby driving the placement box 2 to slide elastically downward so that the suction cup 6 drives the top layer of drawings to be offset from the placement box 2 and then transferred toward the collection box 3.

[0031] The drawing collection and arrangement device provided in this embodiment is used to arrange the chaotically stacked drawings into a unified and orderly state. The words related to position and direction such as "front", "back", "left", and "right" involved in this embodiment are relative to the drawings. Specifically, the support frame 1 includes two vertical plates arranged relative to each other in the front and back directions, and a first connecting plate 103 and a second connecting plate 102 arranged relative to each other in the left and right directions are fixedly connected between the two vertical plates. The placement box 2, the collection box 3 and the suction cup 6 are all located between the two vertical plates. When in use, one of the vertical plates is fixed to the wall or other supporting objects. The placement box 2 is open to one side (i.e., the left side) of the collection box 3. The collection box 3 is located at the lower left of the placement box 2. The driving mechanism is arranged on the support frame 1. The driving mechanism includes a reduction motor 9 and a rotating shaft 401 keyed to the output shaft of the reduction motor 9. The rotating shaft 401 is rotated and arranged between the two vertical plates. The outer peripheral surface of the rotating shaft 401 is fixedly installed with a rotating wheel 4. The reduction motor 9 is started to drive the rotating wheel 4 to rotate counterclockwise. The driving mechanism can also be other forms of driving, as long as it can drive the rotating shaft 401 to rotate counterclockwise. It will not be repeated. The suction cup 6 is connected to the rotating wheel 4. The rotation of the rotating wheel 4 drives the suction cup 6 to rotate synchronously. The suction cup 6 is made of rubber. As is known to all, when the suction cup 6 squeezes an object such as a drawing, the air in the suction cup 6 will be discharged and become a vacuum state, thereby being able to absorb the drawing. When there are multiple drawings, the suction cup 6 will only absorb the topmost drawing. The drawings below the top drawing will not be adsorbed. During the rotation of the suction cup 6, the suction cup 6 will continuously approach the placement box 2 from the top until the suction cup 6 contacts the top drawing in the placement box 2. Under the action of the rotation force of the suction cup 6, the top drawing will be continuously squeezed downward to adsorb the drawing. When squeezing the top drawing downward, the placement box 2 is elastically sliding due to the elastic sliding arrangement. The downward elastic sliding of the placement box 2 causes the suction cup 6 to gradually stagger with the placement box 2. After staggering, the suction cup 6 will drive the adsorbed top drawing to move out of the placement box 2, while the other drawings are still The drawing is then placed in the placement box 2, and at the same time, the placement box 2 is reset under the action of elasticity to wait for the suction cup 6 to absorb the drawings next time. The collection box 3 tilts from bottom to top toward the side away from the placement box 2. The upward side of the collection box 3 and the side facing the placement box 2 are both open, so that the suction cup 6 absorbs the top drawing and slowly rotates toward the collection box 3 so that the drawings can be rotated into the collection box 3. At this time, the drawings are separated from the suction cup 6 and tilted to fall into the collection box 3. Based on this, as the suction cup 6 continues to rotate, the drawings can be tilted and lie one by one in the collection box 3 under the action of gravity, so that the drawings are collected and sorted. Among them, the top height of the collection box 3 is lower than the top height of the suction cup 6, so that the suction cup 6 will not contact the collection box 3 during the rotation process. At the same time, the bottom height of the inner cavity of the collection box 3 is lower than the bottom height of the drawings, so that the drawings can completely enter the collection box 3.In the prior art, when transferring drawings, the rubber wheel presses down the drawings to generate friction between the rubber wheel and the drawings on the top layer, and then the movement of the rubber wheel drives the drawings to move. Although the downward pressure of the rubber wheel can generate friction between it and the drawings on the top layer, it will also increase the friction between the drawings on the top layer and the drawings below it. Therefore, when the rubber wheel moves, it will not only drive the drawings on the top layer to be transferred, but also drive one or more drawings below the top layer to be transferred together, so that the number of drawings transferred each time is not uniform. The multiple drawings in rotation are themselves in a messy state. When they are transferred together, the drawings cannot be arranged in a unified and orderly manner, and it is impossible to transfer only one drawing each time.

[0032] In this embodiment, the suction cup 6 is set to rotate, and the downward extrusion force generated when the suction cup 6 rotates can be used to adsorb the drawings on the top layer in the placement box 2, and the placement box 2 is elastically slidable, so that under the action of the rotational force of the suction cup 6, the placement box 2 can be pushed to slide elastically. During the sliding of the placement box 2, the suction cup 6 will drive the top layer drawings and the placement box 2 to move relative to each other until the suction cup 6 is offset from the placement box 2. After the offset, the suction cup 6 drives the top layer drawings to be transferred toward the collection box 3, and then the top layer drawings are transferred to the collection box 3 for collection and sorting. Compared with the existing technology, the adsorption force of the suction cup 6 is used to only adsorb the drawings on the top layer at a time, so that when the suction cup 6 is offset from the placement box 2, only one drawing on the top layer is moved out of the placement box 2, so that only one drawing is transferred each time, which can effectively solve the shortcomings of the existing technology.

[0033] In this embodiment, the driving mechanism is connected to the suction cup 6 via an inflatable member, which is fixedly connected to the rotating wheel 4. The suction cup 6 is sealed and mounted on the vent of the inflatable member. The suction cup 6 is in communication with the vent. The inflatable member drives air into the suction cup 6 to separate the drawing from the suction cup 6. The inflatable member can inflate the suction cup 6, thereby increasing the pressure inside the suction cup 6 and blowing the drawing off the suction cup 6. By properly controlling the inflation time of the inflatable member, the drawing can be accurately dropped into the collection box 3.

[0034] Furthermore, the inflatable part includes a vent tube 5 with one end closed and the other end open. The closed end of the vent tube 5 is fixedly connected to the rotor 4, and the open end of the vent tube 5 is a vent. The vent tube 5 is fixedly provided with a branch tube 501 connected thereto. The branch tube 501 is dynamically sealed and provided with an action rod 7 with one end extending to the outside thereof. A first return spring 13 is installed between the action rod 7 and the branch tube 501. The action rod 7 rotates synchronously with the rotor 4. When a force is applied to the action rod 7 toward the branch tube 501, the action rod 7 can increase the pressure in the inner cavity of the branch tube 501 and the suction cup 6. At the same time, the first return spring 13 is compressed, and the pressure of the suction cup 6 increases, causing the drawing to separate from the suction cup 6. At this time, the vent is connected, and the gas can be sucked into the branch tube 501. Therefore, after the force on the action rod 7 is removed at this time, the action rod 7 is reset under the elastic force of the first return spring 13.

[0035] Furthermore, the action rod 7 includes a rod body 702 and a piston 703 that are fixedly connected. The diameter of the piston 703 is larger than the diameter of the rod body 702. The dynamic seal (sliding seal) of the piston 703 is set in the branch tube 501. The back and forth movement of the rod body 702 can drive the piston 703 to slide back and forth in the branch tube 501. The sliding of the piston 703 toward the inside of the branch tube 501 is used to realize the inflation of the branch tube 501 and the suction cup 6 by the action rod 7. The end of the free end of the branch tube 501 is fixedly installed with a limit ring 502 for the rod body 702 to slide through. The limit ring 502 is used to limit the piston 703. In the initial state, the piston 703 abuts against the limit ring 502, so that the piston 703 will not continue to slide to the outside of the branch tube 501, so that when the suction cup 6 squeezes the top drawing, the gas in the suction cup 6 can be discharged smoothly to adsorb the drawing.

[0036] In this embodiment, the free end of the rod body 702 is fixedly installed with an extension cross bar 701, the first return spring 13 is located between the extension cross bar 701 and the limit ring 502, and the support frame 1 is elastically rotatably provided with a blocking plate 11 that abuts against the extension cross bar 701, wherein the blocking plate 11 is rotatably connected to the support frame 1 through a raised shaft 1101, and the raised shaft 1101 is fixedly connected or rotatably connected to the blocking plate 11, and the raised shaft 1101 is rotatably connected to the support frame 1, and the blocking plate 11 is elastically rotatably provided with a blocking plate 11 that abuts against the extension cross bar 701. A circular arc rod 1102 is fixedly installed which is concentric with the raised shaft 1101. A fixed block for the circular arc rod 1102 to slide through is fixedly installed on the support frame 1. A limit spring 1103 is sleeved on the circular arc rod 1102. The limit spring 1103 is located between the fixed block and the blocking plate 11. The elastic force of the limit spring 1103 is used to realize the elastic rotation of the blocking plate 11. The elastic force of the limit spring 1103 is greater than the elastic force of the first reset spring 13, so that the limit spring 1103 and the first reset spring 13 are in a closed position. When the springs 13 exert force on each other, the first return spring 13 is compressed and deformed first. Based on this, in the process of the suction cup 6 driving the top drawing to transfer toward the collection box 3, the extended cross bar 701 abuts against the blocking plate 11 to push the piston 703 to slide into the branch pipe 501, driving the gas to flow into the suction cup 6, so that the drawing is separated from the suction cup 6 and falls into the collection box 3. The first return spring 13 is continuously compressed during this process. When the first return spring 13 is compressed to the limit state, as the action rod 7 continues to rotate, the extended cross bar 701 pushes the blocking plate 11 to rotate counterclockwise, causing the limit spring 1103 to be compressed. Until the extended cross bar 701 passes over the blocking plate 11, the blocking plate 11 is reset under the elastic force of the limit spring 1103, and at the same time, the action rod 7 is reset under the action of the first return spring 13 (that is, the piston 703 abuts against the limiting ring 502 again), and the suction cup 6 is staggered with the blocking plate 11 and the collection box 3, so that the suction cup 6 will not be hindered during the rotation process.

[0037] Among them, there are two blocking plates 11 and they are located on both sides of the width direction of the collecting box 3. After the piston 703 slides to the extreme position inside the branch tube 501 (that is, after the first return spring 13 is compressed to the extreme state), the cross bar 701 pushes the two blocking plates 11 to rotate elastically so that the inflatable part passes over the blocking plate 11.

[0038] In this embodiment, the collection box 3 includes an L-shaped bottom plate 301 and two side plates 302 arranged opposite to each other. The L-shaped bottom plate 301 is fixedly connected to the support frame 1 through the first connecting plate 103, and the two side plates 302 are slidably connected to the L-shaped bottom plate 301. The two blocking plates 11 are transmission-connected one-to-one with the two side plates 302. In the process of the two blocking plates 11 being pushed by the cross bar 701, the two side plates 302 are driven to slide toward the L-shaped bottom plate 301 so that the two side plates 302 push the drawings to the center. It can be seen that by using the rotational force of the cross bar 701 to drive the two blocking plates 11 to rotate, the two side plates 302 can be controlled to approach each other, so that the drawings falling into the collection box 3 can be pushed to a specific position, so that the drawings can be collected more neatly. The minimum distance between the two side plates 302 is equal to the width of the drawings.

[0039] Specifically, a group of clamping rods are fixedly installed on the sides of the two side plates 302 that are away from each other, and each group of clamping rods includes two relatively arranged light rods 10, the two light rods 10 are fixedly connected, and a gap is formed between the two light rods 10. An inclined plate 12 inclined toward the L-shaped bottom plate 301 is fixedly installed on the two blocking plates 11, and the two inclined plates 12 are slidably inserted into the gaps of the two groups of clamping rods in a one-to-one manner. When the two blocking plates 11 rotate counterclockwise, the two inclined plates 12 are driven to rotate counterclockwise in the gaps between the corresponding two light rods 10. At this time, the two inclined plates 12 push the two side plates 302 closer to each other, thereby pushing the drawing to the center. When the cross bar 701 is staggered with the two blocking plates 11, the limit spring 1103 drives the two blocking plates 11 and the two inclined plates 12 to rotate clockwise, so that the two side plates 302 slide away from each other to achieve reset.

[0040] The sliding connection between the two side panels 302 and the L-shaped bottom panel 301 is achieved in that sliding rods 303 are fixedly installed on the opposite surfaces of the two side panels 302, and a through hole corresponding to the sliding rod 303 is opened on the L-shaped bottom panel 301, and the sliding rod 303 is slidably plugged into the through hole. There are multiple sliding rods 303 to ensure the stability of the side panels 302.

[0041] The width of the L-shaped bottom plate 301 is smaller than the width of the drawings. When the collected drawings are taken out of the collection box 3 , fingers can pass between the side plates 302 and the L-shaped bottom plate 301 and hold the bottom of the drawings, making the taking out action more convenient.

[0042] In this embodiment, when the suction cup 6 abuts against the top-level drawing, the suction cup 6 is close to the end of the placement box 2 facing the inflatable member, so that the path of sliding friction between the top-level drawing and the drawing below it is shorter, thereby making it difficult for the drawing below the top-level drawing to slide out of the placement box 2 due to the suction cup 6.

[0043] Furthermore, the bottom height of the action rod 7 is not higher than the bottom height of the inner cavity of the placement box 2, so that the action rod 7 blocks the drawings in the placement box 2, preventing the suction cup 6 from causing the drawings below the top drawing to slide out of the placement box 2 during the process of causing the top drawing to be offset from the placement box 2.

[0044] In this embodiment, at least two telescopic rods 8 are fixedly installed between the bottom of the placement box 2 and the second connecting plate 102, and each telescopic rod 8 is provided with a second return spring 801. When the placement box 2 is pressed down by the suction cup 6, the second return spring 801 is compressed and deformed. When the suction cup 6 is offset from the placement box 2, the placement box 2 slides up and returns to its original position under the action of the elastic force of the second return spring 801.

[0045] Among them, a guide plate 201 is fixedly installed on the front and back sides of the placement box 2, and a guide rail 101 corresponding to the two guide plates 201 is fixedly installed on the support frame 1. The guide plate 201 is slidably connected to the guide rail 101 so that the placement box 2 can slide up and down stably.

[0046] In this embodiment, the telescopic rod 8 includes an upper rod and a lower rod, both of which are fixedly mounted with blocks, and the second return spring 801 is located between the two blocks. The top end of the lower rod is slidingly sealed and inserted into the upper rod, and a vent 14 and a one-way valve 15 are fixedly mounted on the upper rod. The one-way valve 15 can only discharge the gas in the upper rod, and the vent 14 can allow gas to enter and exit. When the placement box 2 slides down, the lower rod pushes the gas in the inner cavity of the upper rod out from the vent 14 and the one-way valve 15 to smoothly shorten the telescopic rod 8. The aperture of the vent 14 is not greater than 1 cm, so that when the placement box 2 slides up, the external air is slowly sucked into the vent 14, and then enters the inner cavity of the upper rod, so that the placement box 2 rises slowly. The function of the slow rising of the placement box 2 is to prevent the placement box 2 from pushing the drawings sucked away by the suction cup 6 too hard when rising, thereby preventing the drawings from being pushed too hard and forming creases.

[0047] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.

When the suction cup drives the top sheet of paper to be transferred toward the collection box, the extension cross bar abuts against the blocking plate to push the piston to slide toward the inside of the branch pipe, driving gas to flow into the suction cup, causing the paper to detach from the suction cup and fall into the collection box. There are two blocking plates, which are respectively located on both sides of the collecting box in the width direction. After the piston slides to the limit position inside the branch pipe, the cross bar pushes the two blocking plates to rotate elastically so that the inflatable member passes over the blocking plates.

2. The drawing collection and arrangement device according to claim 1, characterized in that: The collection box includes an L-shaped bottom plate and two side plates arranged opposite to each other. The two side plates are slidably connected to the L-shaped bottom plate, and the two blocking plates are transmission-connected to the two side plates in a one-to-one correspondence. When the two blocking plates are pushed by the cross bar, the two side plates are driven to slide toward the L-shaped bottom plate so that the two side plates push the drawing to the center.

3. The drawing collection and arrangement device according to claim 2, characterized in that: The width of the L-shaped base plate is smaller than the width of the drawing.

4. The drawing collection and arrangement device according to claim 1, characterized in that: When the suction cup contacts the top drawing, the suction cup is close to one end of the placement box facing the inflatable member.

5. The drawing collection and arrangement device according to claim 1, characterized in that: The bottom height of the action rod is not higher than the bottom height of the inner cavity of the placement box, so that the action rod blocks the drawings in the placement box and prevents the drawings below the top drawing from sliding out of the placement box when the suction cup drives the top drawing to be offset from the placement box.
