[0061] Some embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application.

[0062] As described in the background art, after the stacks are processed and removed, an empty magazine is left behind. Currently, this requires manual handling or recycling. Furthermore, before the magazine is used again to carry the stacks, it is necessary to place a piece of paper to protect the loaded stacks. This is currently done manually, one by one, resulting in low efficiency and high labor intensity. Based on this, the present application proposes a magazine conveying device to achieve automatic circulation of magazines and automatic placement of paper in the magazine, thereby improving production efficiency.

[0063] See attached Figure 1 , Figure 1 Schematic diagram of a material box conveying device according to an embodiment of the present application. Figure 1 As shown, in one or more embodiments, the material box conveying device of the present application includes a first conveying mechanism 10 and a paper loading mechanism 20, wherein: the first conveying mechanism 10 is provided with a discharge station M, and the first conveying mechanism 10 is configured to receive an empty material box 40 and convey the material box 40 to the discharge station M; the paper loading mechanism 20 is arranged close to the discharge station M, and the paper loading mechanism 20 is configured to pick up the sulfuric acid paper 30 and move the picked sulfuric acid paper 30 to the material box 40 located at the discharge station M; the first conveying mechanism 10 is also configured to convey the material box 40 containing sulfuric acid paper 30 located at the discharge station M to the next process.

[0064] The material box conveying device of the embodiment of the present application receives or recycles the empty material box 40 returned from the previous process through the first conveying mechanism 10 and conveys the empty material box 40 to the next process that needs the material box, thereby completing the recycling of the material box 40, reducing production costs to a certain extent, and improving production efficiency. In the process of conveying the empty material box 40, the placement of the sulfuric acid paper 30 on the lower layer of the material box is automatically completed through the paper loading mechanism 20, making full use of the material box transportation process, improving the utilization efficiency of the empty material box 40, saving manpower, and meeting the fast-paced production needs.

[0065] In one embodiment, see the attached Figure 1 The paper feeding mechanism 20 includes a material storage component 21, a first drive component 22 and at least one set of picking components 23, wherein:

[0066] The driving end of the first driving component 22 is connected to at least one set of picking components 23. The first driving component 22 is configured to drive at least one set of picking components 23 to move to the storage component 21 to pick up the top layer of sulfuric acid paper 30. The first driving component 22 is also configured to drive at least one set of picking components 23 to move to the discharging station M to release the picked sulfuric acid paper 30 onto the material box 40.

[0067] Specifically, in order to automatically pick up the sulfate paper 30 and place the picked sulfate paper 30 on the material box 40 at the discharging station M, the first drive component 22 drives the picking component 23 to move above the storage component 21. After the picking component 23 picks up the sulfate paper 30 on the uppermost layer in the storage component 21, the first drive component 22 drives the picking component 23 to move to the discharging station M. The picking component 23 places the picked sulfate paper 30 on the material box 40. The sulfate paper 30 is picked up or placed by at least one set of picking components 23, thereby improving the placement efficiency of the sulfate paper 30 and at the same time improving the discharging efficiency of the material box 40.

[0068] In one possible implementation, see the attached Figure 1 and attached Figure 2, the first driving component 22 includes a first driving module 221, a second driving module 222 and a plurality of cylinders 223, the driving end of the first driving module 221 is connected to the second driving module 222, the first driving module 221 drives the second driving module 222 to move horizontally along the X direction, and the plurality of cylinders 223 are all installed at the driving end of the second driving module 222, and the second driving module 222 drives the cylinder 223 to move horizontally along the Y direction. The driving end of each cylinder 223 is connected to a picking component 23, and the cylinder 223 can drive the corresponding picking component 23 to move up and down in the Z direction; in the process of placing the sulfuric acid paper 30, the first driving module 221 drives the second driving module 222 to move, so as to drive the picking component 23 on the second driving module 222 to move along the X direction to above the storage component 21, so that the picking component 23 just corresponds to the sulfuric acid paper 30 in the storage component 21 in the X direction, and the picking component 23 may be in the Y direction with the sulfuric acid paper 30 in the storage component 21 The sulfuric acid paper 30 has a position offset, and the second driving module 222 can drive the cylinder 223 to move and adjust in the Y direction, so that the picking component on the cylinder 223 also corresponds to the sulfuric acid paper 30 in the storage component 21 in the Y direction. The cylinder 223 drives the picking component 23 to rise and fall so that the picking component 23 contacts the sulfuric acid paper 30 on the uppermost layer in the storage component 21. The picking component 23 opens to pick up the sulfuric acid paper 30; after picking up the sulfuric acid paper 30, the cylinder 223 drives the picking component 23 to rise. The first drive module 221 drives the second drive module 222 to move along the X direction to above the corresponding storage station M of the pickup assembly 23. The first drive module 221 and the second drive module 222 adjust the corresponding position between the sulfuric acid paper 30 and the material box 40. When the sulfuric acid paper 30 and the material box 40 are aligned, the cylinder 223 drives the pickup assembly 23 to descend until the pickup assembly 23 abuts the material box 40. The pickup assembly 23 releases the sulfuric acid paper 30 onto the material box 40, completing the placement of the sulfuric acid paper 30. Specifically, the first drive module 221 and the second drive module 222 can be linear modules, and the setting direction of their respective linear guides is consistent with their driving direction.

[0069] In one possible implementation, see the attached Figure 1 and attached Figure 2 In order to improve the placement efficiency of the sulfuric acid paper 30 and the discharging efficiency of the material box 40, the storage assembly 21 is configured as at least one set, and each set of the storage assembly 21 corresponds to a set of the picking assembly 23;

[0070] The discharge station M is provided with at least one discharge position, and the first conveying mechanism 10 is configured to receive the empty material box 40 and convey the material box 40 to each discharge position in sequence;

[0071] The first drive component 22 is configured to drive at least one set of picking components 23 to move to the corresponding storage component 21 at the same time and pick up the topmost paper 30 in each storage component 21 through each picking component 23. The first drive component 22 is also configured to drive each picking component 23 holding the paper 30 to move to the corresponding discharge position and release the held paper 30 to the corresponding material box 40, so that multiple material boxes 40 can place the paper 30 at the same time.

[0072] In one possible implementation, see the attached Figure 1 and attached Figure 2 The storage assembly 21 includes a storage rack 211, a supporting member 212 and a first driving member 213. A storage space with an upper end open for storing multiple stacked sheets of paper 30 is provided in the storage rack 211. The driving end of the first driving member 213 is connected to the supporting member 212. The supporting member 212 is arranged in a liftable manner in the storage space. The supporting member 212 is configured to support multiple stacked sheets of paper 30. The first driving member 213 drives the supporting member 212 to rise to a preset height to lift the multiple sheets of paper 30 in the storage rack 211 upward by a material distance.

[0073] Specifically, the first driving member 213 can be a cylinder. The driving end of the first driving member 213 passes through the storage rack 211 and is connected to the supporting member 212 in the storage space. The first driving member 213 drives the supporting member 212 to rise and fall along the Z direction. Each time the material is fed, the supporting member 212 is driven to rise a material distance along the Z direction, thereby realizing automatic feeding of the sulfate paper 30, facilitating the picking component 23 to pick up the top layer of sulfate paper 30, and ensuring that the picking component 23 picks up the sulfate paper 30 at the same position height each time, thereby improving the paper feeding efficiency of the paper feeding mechanism 20, and the feeding structure is simple and the feeding is stable and reliable.

[0074] In a possible embodiment, the carrier 212 is tilted in the material storage space, and the first drive assembly 22 is configured to drive the pickup assembly 23 to pick up the tilted sulfuric acid paper 30 and place it on the carrier plate 41 of the corresponding material box 40.

[0075] Specifically, the cylinder 223 of the first driving component 22 can be installed on the second driving module 222 at an angle, so that the picking component 23 installed on the driving end of the cylinder 223 is also in an inclined state. The inclination angle and direction of the picking component 23 are consistent with the inclination angle and direction of the carrier 212. The inclined picking component 23 can directly pick up the sulfuric acid paper 30 in an inclined state in the storage space, which is suitable for carrying a material box with stacked sheets in an inclined state.

[0076] In one possible embodiment, the material box conveying device includes a material box 40, which includes a base 42 and a supporting plate 41. The supporting plate 41 is installed obliquely on the base 42. The supporting plate 41 is used to support the stacked sheets. The supporting member 212 of the storage assembly 21 is configured to make the inclination angle and direction of the multiple sheets of sulfuric acid paper 30 stacked in the storage space consistent with the supporting plate 41.

[0077] Specifically, in order to stably load the stacked sheets, the supporting plate 41 of the material box 40 is set to an inclined state. In order to facilitate the placement of the sulfate paper 30, the supporting member 212 of the storage component 21 is set to an inclined state, and the inclination angle and direction are consistent with the supporting plate 41. The cylinder 223 of the first drive component 22 can be installed on the second drive module 222 at an angle, so that the picking component 23 installed on the driving end of the cylinder 223 is also in an inclined state. The inclination angle and direction of the picking component 23 are consistent with the inclination angle and direction of the supporting member 212. The inclined picking component 23 can directly pick up the sulfate paper 30 in an inclined state in the storage space and place it on the supporting plate 41 of the material box 40, thereby realizing the precise placement of the sulfate paper and improving production efficiency.

[0078] In one embodiment, see the attached Figure 3 , the material box conveying device also includes a second conveying mechanism 50, a handling mechanism 60 and a third conveying mechanism 70;

[0079] The second conveying mechanism 50 is provided with a stacking processing station N. The second conveying mechanism 50 is configured to receive the magazine 40 containing stacked sheets and convey the magazine 40 to the stacking processing station N for stacking processing.

[0080] The transport mechanism 60 is configured to pick up the laminates in the magazine 40 after processing at the laminate processing station N and transport them to the next process;

[0081] The second conveying mechanism 50 is further configured to convey the empty magazine 40 from which the stacked sheets have been removed to the third conveying mechanism 70 ;

[0082] The third conveying mechanism 70 is configured to receive the empty magazine 40 conveyed by the second conveying mechanism 50 and convey the empty magazine 40 to the first conveying mechanism 10 .

[0083] Specifically, a stacking processing mechanism is provided on the stacking processing station N of the second conveying mechanism 50, and the stacking processing mechanism is used to process the stacking, for example, to perform corresponding inspections on the stacking, such as appearance, neatness inspection, etc. After the inspection, the qualified stacking will be taken away for the next process, such as secondary inspection or packaging. In this example, the stacking in the material box 40 after processing is taken away by the conveying mechanism 60, and the second conveying mechanism 50 continues to convey the empty material box 40 with the stacking removed to the third conveying mechanism 70, which is recycled and transported by the third conveying mechanism 70 to the first conveying mechanism 10 for placing sulfuric acid paper and sending out the empty material box 40. The third conveying mechanism 70 is set to smoothly send the material box 40 after entering the processing equipment to the outside of the equipment, so as to facilitate the first conveying mechanism 10 to discharge the empty material box on one side of the equipment. Through the coordinated transportation of the second conveying mechanism 50, the third conveying mechanism 70 and the first conveying mechanism 10, the circular conveying process of feeding, processing and recycling of the material box 40 is realized, which saves production costs, has a compact structure and occupies little space.

[0084] In one possible implementation, see the attached Figure 3 The material box conveying device also includes a lifting assembly 80, the lifting assembly 80 includes a second driving member 81 and a first conveying assembly 82, the driving end of the second driving member 81 is connected to the first conveying assembly 82, and the second driving member 81 is configured to drive the first conveying assembly 82 to move alternately to the first position or the second position;

[0085] The first position is close to the discharge end of the second conveying mechanism 50 , and the first conveying assembly 82 located at the first position is configured to receive and temporarily store the empty material box 40 conveyed by the second conveying mechanism 50 ;

[0086] The second position is close to the feeding end of the third conveying mechanism 70 , and the second position is lower than the height of the first position. The first conveying assembly 82 located at the second position is configured to convey the temporarily stored empty material box 40 to the third conveying mechanism 70 .

[0087] Specifically, such as Figure 3 and Figure 4 As shown, the second driving member 81 can adopt a linear module, and the second driving member 81 drives the first conveying assembly 82 to rise and fall vertically along the Z direction, so that the first conveying assembly 82 is alternately moved to the first position or the second position; the first conveying assembly 82 includes a first pulley assembly 821 and a second pulley assembly 822, and the transportation directions of the first pulley assembly 821 and the second pulley assembly 822 are different. The first pulley assembly 821 or the second pulley assembly 822 is used to receive the material box 40 conveyed by the second conveying mechanism 50 at the first position, and convey the material box 40 to the third conveying mechanism 70 or other stacking processing procedures at the second position, such as stacking maintenance. Figure 4The first pulley assembly 821 and the second pulley assembly 822 are arranged perpendicular to each other. The first pulley assembly 821 can drive the material box 40 thereon to move along the X direction, and the second pulley assembly 822 can drive the material box 40 thereon to move along the Y direction, thereby realizing the transportation of the material box 40 in different directions, providing a lifting assembly 80 with a simple structure and easy transportation. It should be noted that the figure is only a schematic conveying direction, and the pulley assembly can be set according to the actual production line direction. The figure does not limit the specific structure of the pulley assembly.

[0088] By setting up the lifting assembly 80, the empty material boxes circulated by the second conveying mechanism 50 are transferred to the third conveying mechanism 70, and the empty material boxes are recovered by the third conveying mechanism 70, so that each conveying mechanism can convey and circulate the material boxes 40 in the same space, making the entire material box conveying device compact in structure, small in space occupation, and high in transportation efficiency.

[0089] In one embodiment, see Figure 3 The material box conveying device also includes a second conveying component 90, which is configured to convey the material box 40 in at least two directions; the second conveying component 90 is arranged between the third conveying mechanism 70 and the first conveying mechanism 10; the second conveying component 90 is configured to receive the empty material box 40 conveyed by the third conveying mechanism 70 along the first direction and convey the material box to the receiving end of the first conveying mechanism 10 along the second direction; the first conveying mechanism 10 is configured to convey the empty material box 40 to the discharging station M along the second direction, and the second conveying component 90 realizes that even if the conveying directions of the third conveying mechanism 70 and the first conveying mechanism 10 are inconsistent, the transfer of the material box 40 between the two can be completed, which provides more possibilities for the setting space of the conveying mechanism, improves the applicability of the conveying mechanism setting, has a compact structure, and saves the occupied space of the entire device.

[0090] Specifically, the second conveying assembly 90 may use at least two groups of pulley assemblies arranged in different directions to convey the material box 40 in at least two directions.

[0091] In one possible implementation, see Figure 3 and Figure 5 The material box conveying device also includes a third driving member 91, a driving end of the third driving member 91 is connected to the second conveying component 90, and the third driving member 91 is configured to drive the second conveying component 90 to rotate to change the conveying direction of the second conveying component 90.

[0092] Specifically, the third driving member 91 can be a rotating motor. The third driving member 91 drives the second conveying component 90 to rotate, thereby changing the conveying direction of the second conveying component 90. In the process of conveying the material box 40, the third conveying mechanism 70 conveys the material box 40 along the X direction. The third driving member 91 drives the second conveying component 90 to rotate so that the conveying direction of the second conveying component 90 is consistent with that of the third conveying mechanism 70, that is, the second conveying component 90 receives the material box 40 from the third conveying mechanism 70 along the X direction. The third driving member 91 drives the second conveying component 90 to rotate again so that the conveying direction of the second conveying component 90 is consistent with that of the first conveying mechanism 10. The second conveying component 90 conveys the material box 40 to the first conveying mechanism 10 along the Y direction. In this example, the X direction and the Y direction are perpendicular to each other, which can save the space occupied by the device.

[0093] By setting the third driving member 91, the second conveying assembly 90 can receive the material box 40 in any direction and feed the material box 40 along any conveying direction by rotation, providing more setting possibilities for the first conveying mechanism 10 and the third conveying mechanism 70, which is conducive to compact structure and space saving.

[0094] In one embodiment, see Figure 5 A blowing assembly 71 is installed on the discharge end of the third conveying mechanism 70, and the blowing assembly 71 is configured to blow and clean the empty material box 40 passing through.

[0095] Specifically, the blowing assembly 71 can span the conveying surface of the third conveying mechanism 70, and its height is greater than the height of the material box 40. When the third conveying mechanism 70 conveys the material box 40, the material box 40 passes through the blowing assembly 71. The blowing assembly 71 cleans the recovered empty material box 40 and blows away the impurities on the material box 40 to avoid affecting the quality of subsequent loaded stacks.

[0096] In one embodiment, see Figure 6 The material box conveying device further includes a second driving assembly 11, a driving end of the second driving assembly 11 is connected to the first conveying mechanism 10, and the second driving assembly 11 is configured to drive the first conveying mechanism 10 to move alternately to the third position or the fourth position;

[0097] The third position is close to the discharge end of the third conveying mechanism 70 , and the first conveying mechanism 10 at the third position is configured to receive the empty material box conveyed by the third conveying mechanism 70 and convey it to the discharge station M;

[0098] The fourth position is consistent with the height of the material receiving end of the second conveying mechanism 50. The first conveying mechanism 10 at the fourth position is configured to place the picked-up sulfuric acid paper into the empty material box 40 at the discharge station M by the paper loading mechanism 20, and convey the material box 40 containing sulfuric acid paper 30 to the next process.

[0099] Specifically, the second drive component 11 can adopt a linear drive module. The second drive component 11 drives the first conveying mechanism 10 to move up and down as a whole, so that the first conveying mechanism 10 can be at different heights. At the third position, it is consistent with the height of the third conveying mechanism 70, and can be used to receive the empty material box 40 output from the inside of the equipment from the third conveying mechanism 70 at the lower layer. In order to facilitate the placement of sulfuric acid paper 30 and the delivery of the material box 40, the second drive component 11 drives the first conveying mechanism 10 to rise to the fourth position. The fourth position is consistent with the height position of the second conveying mechanism 50. At this position, it is closer to the paper loading mechanism 20, which can facilitate the paper loading mechanism 20 to place sulfuric acid paper 30. At this position height, it is convenient for other devices for transporting material boxes to deliver materials to the second conveying mechanism 50 at the same height. The empty material box 40 is transported to the sorting machine and other equipment at the first conveying mechanism 10 for receiving the materials, thereby improving the efficiency of receiving and feeding the materials, thereby improving the overall production efficiency, and ensuring the accuracy of receiving and feeding the materials at the same height.

[0100] By setting the second drive component 11, it is possible to drive the first conveying mechanism 10 to rise and fall to change the height position of the first conveying mechanism 10, so that the material box 40 can be received at different heights and the sulfuric acid paper 30 can be placed at an appropriate position, which is convenient for the material box 40 to enter the next process, and the fourth position is consistent with the height of the receiving end of the second conveying mechanism 50, which is convenient for the handling device that feeds the second conveying mechanism 50 to pick up the material box 40 loaded with sulfuric acid paper 30, thereby realizing the recycling of the material box 40. At the same time, the second conveying mechanism 50 is designed to be liftable, so that the second conveying mechanism 50 and the third conveying mechanism 70 can be set up in the upper and lower layers, saving space and making the overall transportation structure compact.

[0101] In one embodiment, see the attached Figure 7 A limiting assembly 12 is provided on the first conveying mechanism 10, and the limiting assembly 12 includes a limiting bar 121, a pushing block 122 and a fourth driving member 123; the limiting bar 121 and the pushing block 122 are relatively arranged on both sides of the discharging station M, and the driving end of the fourth driving member 123 is connected to the pushing block 122. The fourth driving member 123 is configured to drive the pushing block 122 to approach or move away from the limiting bar 121 to clamp or loosen the material box 40 on the discharging station M.

[0102] Specifically, the fourth driving member 123 can be a pneumatic cylinder, and the push block 122 is arranged parallel to the opposite side of the limit bar 121, and the setting direction is consistent with the conveying direction of the first conveying mechanism 10. If the first conveying mechanism 10 has two conveyor belts, the push block 122 and the limit bar 121 are arranged on the outside of the conveyor belts. The fourth driving member 123 drives the push block 122 to move toward or away from the limit bar 121, which can clamp the material box 40 on the discharge station M, preventing the material box 40 from shaking when the second driving assembly 11 drives the first conveying mechanism 10 to rise and fall, thereby improving the stability of the first conveying mechanism 10 in conveying the material box 40. In the present application, the limit assembly 12 can be multiple sets, and the discharge station M has multiple discharge positions, each of which is provided with a limit assembly 12.

[0103] See attached Figure 1-Figure 7 , an optional working process of the material box conveying device of the embodiment of the present application is:

[0104] The second conveying mechanism 50 receives the magazine 40 containing the laminated sheets and conveys the magazine 40 to the laminated sheet processing station N for laminated sheet processing;

[0105] The second conveying mechanism 50 continues to convey the magazine 40 at the stacking processing station N to its discharge end. During this conveying process, the transport mechanism 60 picks up the stacking sheets in the magazine 40 and transports them to the next processing step of the stacking sheets, such as secondary inspection or packaging. The empty magazine 40 is left to the discharge end.

[0106] After the first conveying assembly 82 of the lifting assembly 80 receives the empty material box 40 delivered by the second conveying mechanism 50 at the first position, the second driving member 81 drives the first conveying assembly 82 to the second position and delivers the empty material box 40 to the third conveying mechanism 70;

[0107] The third conveying mechanism 70 receives the empty material box 40 conveyed by the first conveying assembly 82 and blows the empty material box 40 through the blowing assembly 71 before conveying it to the second conveying assembly 90 ;

[0108] The second conveying assembly 90 receives the material box 40 conveyed by the third conveying mechanism 70 in the first direction and conveys the material box 40 to the first conveying mechanism 10 along the second direction;

[0109] The first conveying mechanism 10 receives the material box conveyed by the second conveying assembly 90 at the third position and conveys it to the discharge station M. The limiting assembly 12 on the discharge station M clamps the corresponding material box 40;

[0110] The second drive assembly 11 drives the first conveying mechanism 10 to rise to the fourth position. At the fourth position, the paper loading mechanism 20 picks up the paper 30 and moves the picked-up paper 30 to the material box 40 located at the discharge station M, completing the placement of the lower layer of paper 30 on the material box 40.

[0111] After the sulfuric acid paper 30 is placed, the device for transporting the material box 40 can transport the material box 40 to a receiving station where the material box 40 is needed to receive the stacked sheets, thereby completing the reuse of the material box 40.
