[0033] Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings.

[0034] As Figures 1-3 shown, the application provides a kind of material box stopper 10, wherein the material box stopper 10 includes stop block 11, particle 12 and buffer plate 13, at least one containing groove 111 is opened on the side surface of stop block 11, multiple particles 12 are stacked in each containing groove 111, and particle 12 can move in containing groove 111, buffer plate 13 is provided at the slot of each containing groove 111, buffer plate 13 is configured to block particle 12 in corresponding containing groove 111, and buffer plate 13 will be deformed in the direction towards the groove bottom of containing groove 111 to press towards particle 12 in containing groove 111 when stressed.

[0035] When material box stopper 10 is applied in material box, material box stopper 10 can be used as the side wall of material box, when sheet body 20 with a certain speed flies into material box, the edge of sheet body 20 first touches buffer plate 13 of material box stopper 10, then sheet body 20 falls into material box, when the edge of sheet body 20 touches buffer plate 13, it will promote buffer plate 13 to deform towards the groove bottom of containing groove 111, and buffer plate 13 will suppress particle 12 in containing groove 111 when deformed, promote particle 12 to move, so that the kinetic energy of sheet body 20 will be consumed by the deformation of buffer plate 13 and the movement of particle 12, thereby avoiding sheet body 20 rebounding and damaging, so that sheet body 20 is collected in material box neatly.

[0036] Optionally, as Figure 4 shown, material box stopper 10 further includes at least one containing bag 14, at least one containing bag 14 is placed in each containing groove 111, and each containing bag 14 contains particle 12;The space volume occupied by all particles 12 in containing bag 14 is less than the internal volume of containing bag 14, and buffer plate 13 is configured to block containing bag 14 in the containing groove 111.

[0037] As Figure 3 shown, particle 12 can be directly stacked in containing groove 111, and the slot of containing groove 111 is blocked by buffer plate 13 to avoid particle 12 from falling out of containing groove 111. Or as Figure 4As shown, the particles 12 are first loaded into the containing bag 14, and then the containing bag 14 is placed into the containing groove 111. The containing bag 14 can be a transparent plastic sealed bag in the market, so as to observe the amount of the particles 12 loaded in the containing bag 14. Of course, the containing bag 14 can also be any bag capable of containing the particles 12. The particles 12 in the containing groove 111 can be all loaded into the containing bag 14, or part of the particles 12 can be loaded into the containing bag 14, and part of the particles 12 can be directly scattered in the containing groove 111. For the particles 12 contained in the containing bag 14, the space volume occupied by all the particles 12 in the containing bag 14 is less than the internal volume of the containing bag 14, that is, the containing bag 14 cannot be filled with the particles 12, and it is necessary to ensure that the particles 12 have a certain moving space in the containing bag 14. Under the premise of ensuring that the particles 12 have a certain moving space in the containing bag 14, the particles 12 in the containing bag 14 cannot be too few. When the particles 12 are too few, the particle pile formed by the particles 12 piling up together is small, and the contact surface between the particle pile and the buffer plate 13 is also small, so that the buffer plate 13 cannot well transmit kinetic energy to the particles 12. The particles 12 in the containing bag 14 also cannot be too many. When the particles 12 are too many, the particles 12 are pressed by each other due to their own gravity, so that the particle pile is compressed, and the particles 12 are difficult to be pushed.

[0038] Optionally, the containing groove 111 is at least two, and each containing groove 111 is arranged in the first direction X.

[0039] Figures 1-3 Optionally, the number of the containing groove 111 is two. When the material box stop piece 10 is applied to the material box, the material box stop piece 10 serves as a side wall of the material box, and the first direction X is the height direction of the side wall of the material box, that is, the containing groove 111 is arranged in the height direction of the side wall of the material box, so that the buffer plate 13 has a longer coverage range in the height direction of the side wall of the material box, and the sheet body 20 flying at different heights can all touch the buffer plate 13, so that the application range is wider. In addition, the containing groove 111 is designed to be more than two, so as to disperse the particles 12 in the plurality of containing grooves 111. If the containing groove 111 is only one, in order to make the buffer plate 13 have a longer coverage range in the height direction of the side wall of the material box, the height of the buffer plate 13 and the height of the containing groove 111 are bound to be high, and the height of the particle pile is also high, that is, too many particles 12 piling up together are easy to make the particle pile compressed, and the particles 12 are difficult to be pushed, so that the buffering effect is poor. Therefore, the above problems can be avoided by arranging a plurality of containing grooves 111.

[0040] Optionally, in order to avoid the frictional resistance of the opening of the containing groove 111 to the buffer plate 13 when the buffer plate 13 is deformed by force, and to ensure that the buffer plate 13 can be normally deformed, the area of the buffer plate 13 is less than the area of the opening of the containing groove 111, so that the four sides of the buffer plate 13 are avoided from contacting the containing groove 111 as much as possible, such asFigure 2 As shown, there is a gap between the perimeter of the buffer plate 13 and the perimeter of the opening of the receiving groove 111.

[0041] The following two methods can be used to install the buffer plate 13:

[0042] Method 1: The material box stop 10 also includes an elastic membrane, which covers the buffer plate 13 at the opening of the receiving groove 111. The elastic membrane can be a single sheet of elastic film. Specifically, the entire elastic film can be adhered to the outer surface of all buffer plates 13 and then to the stop block 11, or the edge of the elastic film can be pressed onto the stop block 11 by a first pressing block, which is then locked and fixed to the stop block 11 by a first screw. Alternatively, the elastic membrane can be multiple elastic film units, with one elastic film unit corresponding to each buffer plate 13. The elastic film unit is adhered to the outer surface of the corresponding buffer plate 13 and is also adhered to the stop block 11, or the edge of the elastic film unit can be pressed onto the stop block 11 by a second pressing block, which is then locked and fixed to the stop block 11 by a second screw. The elastic membrane can be made of PVC material, which has a certain degree of elasticity to allow the buffer plate 13 to deform.

[0043] Method 2: The material box stop 10 also includes tape, which covers the buffer plate 13 at the opening of the receiving groove 111. The tape is attached to the outer surface of the buffer plate 13, and the two ends of the tape are attached to the outer surface of the stop 11, thus realizing the installation of the buffer plate 13. To ensure that the buffer plate 13 can spring and deform, the tape does not need to be tensioned.

[0044] To simplify the drawings, Figure 1 , Figure 2 The elastic membrane and tape are not shown in the drawing.

[0045] Optionally, the particles 12 are spherical. When the particles 12 are spherical, they can move relatively easily, so as to consume more kinetic energy of the sheet 20.

[0046] Optionally, the diameter of the particles 12 ranges from 1mm to 3mm, and the particles 12 are metal spheres. The diameter of the particles 12 can be 1mm, 2mm, 3mm, or other values ​​within this range. Relative movement of the particles 12 within this diameter range is easier. Furthermore, since the particles 12 are metal spheres, metal is heavier than other materials such as plastic for the same volume. When the buffer plate 13 is impacted and deformed, pushing the particles 12, the buffer plate 13 recovers its deformation. Because the particles 12 are relatively heavy, they fall more easily due to gravity, thus re-accumulating into a particle pile. This allows the buffer plate 13 to deform and push the particle pile again when the next sheet 20 impacts it, enabling the particles 12 to move and improving the cushioning effect.

[0047] Optionally, the depth of the accommodating groove 111 ranges from 5mm to 10mm. The depth of the accommodating groove 111 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm or other values within the range. Within the depth range, the particles 12 are easy to pile into a particle pile, and the particle pile can be pushed to move when the buffer plate 13 deforms.

[0048] For the material of the buffer plate 13, the buffer plate 13 can be a rubber plate. The rubber plate has good buffering effect and is wear-resistant. Of course, the buffer plate 13 can also be made of polyurethane or other materials that can deform and have a buffering function.

[0049] Optionally, the ratio of the volume of the space occupied by all the particles 12 in the accommodating bag 14 to the internal volume of the accommodating bag 14 ranges from 1 / 2 to 3 / 4. The ratio of the volume of the space occupied by all the particles 12 in the accommodating bag 14 to the internal volume of the accommodating bag 14 can be 1 / 2, 2 / 3 or 3 / 4, or other values within the range, as long as the buffer plate 13 can be well pressed to move the particles 12 when the buffer plate 13 is impacted, so as to consume the kinetic energy of the sheet body 20 when it is impacted.

[0050] As shown in Figures 5-6 The present application also provides a sheet body magazine. The sheet body magazine comprises a bottom plate 30, a blocking piece 40 and at least one magazine blocking piece 10. All the magazine blocking pieces 10 are arranged at a first edge of the bottom plate 30, and the blocking piece 40 is arranged at a second edge adjacent to the first edge of the bottom plate 30. The bottom plate 30, the blocking piece 40 and all the magazine blocking pieces 10 enclose a cavity for containing the sheet body 20. The blocking piece 40 and all the magazine blocking pieces 10 are used to block two adjacent edges of the sheet body 20, and the buffer plate 13 of the magazine blocking piece 10 faces the cavity.

[0051] When the sheet body magazine is used, the bottom plate 30 can be arranged horizontally or obliquely. The specific oblique direction is that the first corner of the bottom plate 30 is inclined downward, and the second corner opposite to the first corner is inclined upward. The first corner of the bottom plate 30 is the corner clamped by the first edge and the second edge of the bottom plate 30. In this way, after the sheet body 20 enters the sheet body magazine, the sheet body 20 will slide toward the first corner of the bottom plate 30 due to the inclination of the bottom plate 30, so that the two adjacent edges of the sheet body 20 are respectively attached to the blocking piece 40 and the magazine blocking piece 10, and the sheet body 20 is ensured to be neatly stacked into the sheet body magazine. Figure 6 The sheet body magazine contains stacked sheet bodies 20, and the stacked sheet bodies 20 are simplified diagrams.

[0052] In the sheet magazine, the magazine stopper 10 is vertically arranged at the first edge of the bottom plate 30, and the accommodating grooves 111 in the magazine stopper 10 are arranged at intervals in the first direction X which is perpendicular to the plate surface of the bottom plate 30. The magazine stopper 10 can be one, two or more. When the magazine stopper 10 is more than one, the magazine stoppers 10 are arranged at intervals along the length direction of the first edge of the bottom plate 30. For example, Figures 5-6 In the embodiment, the magazine stopper 10 is two, and the two magazine stoppers 10 jointly block one side edge of the sheet 20. The buffer plates 13 in the two magazine stoppers 10 all face the sheet 20, so that the sheet 10 can touch the buffer plates 13 when flying into the sheet magazine.

[0053] The stopper 40 in the sheet magazine of the present application can be Figure 6 the stop plate in the above embodiment, or can be a plurality of stop bars arranged at intervals along the length direction of the second edge of the bottom plate 30, as long as the other side edge of the sheet 20 can be blocked and positioned. The stopper 40 is also arranged vertically to the plate surface of the bottom plate 30.

[0054] The present application also provides a sheet conveying and storing device, which comprises the above sheet magazine and a conveying mechanism for conveying the sheet 20. The sheet magazine is arranged at the output end of the conveying mechanism, and the edge of the sheet 20 conveyed by the conveying mechanism first contacts the buffer plate 13 and then falls into the sheet magazine. The buffer plate 13 is configured to be deformed towards the direction of approaching the groove bottom of the accommodating groove 111 and to press the particles 12 under the contact of the sheet 20, and the buffer plate 13 is configured to restore the deformation by itself.

[0055] The conveying mechanism can adopt various structural forms. For example, the conveying mechanism can adopt a common belt type conveying line, the conveying surface of the belt type conveying line faces upward, and the sheet 20 is arranged on the upper conveying surface. Alternatively, the conveying mechanism can adopt an upper suction conveying line, which comprises a suction assembly and a rotatable belt. The conveying surface of the belt faces downward, and the suction assembly sucks the sheet 20 to the lower surface of the belt by Bernoulli principle, so that the belt can convey the sheet 20. The sheet magazine of the present application can collect the sheet 20 conveyed by the above conveying mechanism.

[0056] The conveying mechanism continuously operates in the process of conveying the sheet 20, so that the sheet 20 conveyed by the conveying mechanism has a certain speed. The sheet magazine is arranged at the output end of the conveying mechanism, and the buffer plate 13 in the sheet magazine needs to be arranged towards the sheet 20. After the sheet 20 is output from the output end of the conveying mechanism, the edge of the sheet 20 first contacts the buffer plate 13, the buffer plate 13 is deformed and presses the particles 12, the kinetic energy of the sheet 20 is consumed by the buffer plate 13 and the particles 12, so that the sheet 20 will not rebound, and the sheet 20 will be neatly stacked in the sheet magazine.

[0057] Optionally, when the buffer plate 13 restores the deformation, the outer plate surface of the buffer plate 13 protrudes from the slot end surface 112 of the accommodating slot 111 by a distance of at least 1 mm. That is, when the buffer plate 13 is not impacted by the sheet 20, the buffer plate 13 is ensured to protrude from the slot end surface 112 of the accommodating slot 111, so that the sheet 20 output from the output end of the conveying mechanism can touch the buffer plate 13. The protruding distance can be 1 mm, 2 mm, 3 mm, 4 mm, or other values that can meet the above-mentioned buffering function.

It is intended that the specification and examples be considered as exemplary only, with the true scope and spirit of the application being indicated by the following claims.
