[0029] See also Figure 1 and Figure 2 An embodiment of the utility model provides a stacking device, including a stacking table, a stacking robot and a loading device. The loading device is used to load a material box A storing sheets to a material picking station a, and unload an empty material box at the material picking station a. The stacking robot is used to suck the sheets in the material box A at the material picking station a, and stack the sucked sheets on the stacking table.

[0030] In the embodiment of the present application, the feeding device includes a silo 10, a feeding mechanism 20 and a pushing mechanism (not shown). The silo 10 is used to carry a plurality of material boxes A, and each material box A is stacked and placed in the silo 10. The pushing mechanism includes a gripping portion 31 (see FIG. 20 ) for gripping or releasing the material box A. Figure 2 ), the grabbing part 31 can be controlled to move along the preset direction X to drive the grabbed material box A to transfer between the silo 10 and the material taking station a. The lifting mechanism 20 includes a lifting drive 21 and a lifting member 22 connected to the driving end of the lifting drive 21. The lifting drive 21 is used to drive the lifting member 22 to lift each material box A in the silo 10, so that the material box A located on the uppermost layer and the grabbing part 31 are opposite to each other in the preset direction X, so that the grabbing part 31 can grab a material box A stacked on the uppermost layer when it moves to the silo 10 along the preset direction X. It should be noted that the lifting drive 21 can adopt an electric cylinder. Of course, in other embodiments, the lifting drive 21 can also adopt other linear drive modules, as long as it can drive the lifting member 22 to rise or fall in the vertical direction, which is not limited here.

[0031] When the above-mentioned loading device is actually used, multiple material boxes A filled with tablets are stacked and placed in the material bin 10, and the grabbing part 31 of the pushing mechanism moves to the material bin 10 along the preset direction X and grabs a material box A located at the top layer. Then, the grabbing part 31 of the pushing mechanism moves toward the material picking station a along the preset direction X until the grabbed material box A is driven to move to the material picking station a. At this time, the stacking robot grabs the tablets in the material box A at the material picking station a and stacks them on the stacking table.

[0032] After all the sheets in the material box A at the material picking station a are taken away (the material box A without sheets is an empty material box), the grasping part 31 of the pushing mechanism moves toward the silo 10 until the empty material box is driven back into the silo 10 and stacked on the top layer of each material box A. At this time, the grasping part 31 of the pushing mechanism releases the empty material box A. The top empty material box in the silo 10 is taken away manually or automatically. Then, the lifting driving part 21 drives the lifting part 22 to move upward, so that the lifting part 22 lifts each material box A in the silo 10 until the top material box A in each material box A reaches a height relative to the grasping part 31 in the preset direction X. Then, the grasping part 31 of the pushing mechanism grabs the material box A at the top and moves toward the material picking station a along the preset direction X until the grasping part 31 drives the grabbed material box A to move to the material picking station a.

[0033] In this way, each time after all the sheets in the material box A at the material picking station a are used up, the grabbing part 31 pushes the empty material box A back to the silo 10, and then pulls the material box A storing the sheets to the material picking station a. The loading and unloading process of the material box A is simple and fast. During this process, the stacking equipment does not need to be shut down and can perform stacking operations normally, which is beneficial to improving production efficiency.

[0034] It should be noted that since only one material box A is transferred to the material picking station a each time, and the empty material box is returned to the silo 10 along the original route, and the material boxes A in the silo 10 are stacked, it is beneficial to make the structure of the loading device more compact, thereby greatly reducing the required occupied space.

[0035] Furthermore, a photoelectric sensor 11 is installed on the silo 10 to detect whether there is a material box A in the silo 10. If the photoelectric sensor 11 detects that there is no material box A in the silo 10, an alarm can be issued to remind the operator to load the material box A filled with tablets into the silo 10 in time.

[0036] In an embodiment of the present application, the feeding device further includes a support mechanism 50 arranged between the silo 10 and the material taking station a, and the support mechanism 50 is used to support the material box A moving between the silo 10 and the material taking station a. After the grabbing portion 31 grabs the material box A in the silo 10, it moves along the preset direction X, thereby driving the material box A in the silo 10 to the support mechanism 50, and moves toward the material taking station a on the support mechanism 50 until it reaches the material taking station a. When the material box A in the material taking station a becomes an empty material box, the grabbing portion 31 moves toward the silo 10 along the preset direction X, thereby driving the empty material box to move toward the silo 10 on the support mechanism 50 until the empty material box enters the silo 10. In this way, the support mechanism 50 is used to support the material box A transferred between the silo 10 and the material taking station a to prevent the material box A from flipping over or even falling.

[0037] Specifically in the embodiment, the support mechanism 50 includes a support frame 51 and a plurality of guide wheels 52 mounted on the support frame 51. The support frame 51 has a transfer channel (not shown) extending longitudinally along a preset direction X. A plurality of guide wheels 52 are provided on both sides of the transfer channel. The plurality of guide wheels 52 are used to confine the passing material box A within the transfer channel, that is, each guide wheel 52 guides the passing material box A so that the material box A moves along the preset direction X within the transfer channel. In this way, under the guiding action of each guide wheel 52, the material box A can accurately enter and exit the material bin 10 and the material retrieving station a, ensuring that the material box A can accurately transfer between the material bin 10 and the material retrieving station a.

[0038] Furthermore, the support frame 51 has two support bars 53, which are arranged side by side and extend longitudinally along the preset direction X between the silo 10 and the material-retrieving station a. The two support bars 53 form the above-mentioned transfer channel, which is used to jointly support the material box A passing through. The guide wheels 52 are arranged in two rows, and the guide wheels 52 in each row are arranged at intervals along the preset direction X. The two rows of guide wheels 52 are respectively located on the outside of the two support bars 53, so that the two rows of guide wheels 52 limit the passing material box A within the transfer channel, avoiding the deviation of the moving trajectory of the material box A, resulting in the inability to accurately enter the silo 10 or the material-retrieving station a.

[0039] Specifically in the embodiment, the material pushing mechanism includes a material pushing movable seat (not shown) and a material pushing driving member 32. The material pushing movable seat is movably connected to the support frame 51 along a preset direction X. The material pushing driving member 32 is installed on the support frame 51, and the driving end of the material pushing driving member 32 is connected to the material pushing movable seat, so that the material pushing driving member 32 can drive the material pushing movable seat to move relative to the support frame 51 along the preset direction X. The gripping portion 31 is installed on the material pushing movable seat, so that the gripping portion 31 can move along the preset direction X with the material pushing movable seat, and then the gripping portion 31 drives the material box A to transfer between the silo 10 and the material taking station a.

[0040] Optionally, the pusher movable seat is installed on the support frame 51 via guide components such as guide rails or guide rods, so that the movement of the pusher movable seat relative to the support frame 51 is guided by guide components such as guide rails or guide rods, so that the movement accuracy of the pusher movable seat along the preset direction X meets the design requirements.

[0041] Optionally, the gripping portion 31 includes a clamping cylinder 311 and a clamping claw 313, wherein the clamping cylinder 311 is mounted on the material pushing movable seat, and the clamping claw 313 is mounted on the driving end of the clamping cylinder 311. Each material box A has a clamping mating portion A1 for the clamping claw 313 to clamp. The clamping cylinder 311 can drive the clamping claw 313 to clamp or release the clamping mating portion A1 on the material box A. Of course, in other embodiments, the gripping portion 31 can also adopt other gripping structures, as long as it can achieve clamping or release of the clamping mating portion A1 on the material box A, which is not limited here.

[0042] In the embodiment of the present application, the loading device further includes a positioning mechanism 60 arranged at the material picking station a. The positioning mechanism 60 can be controlled to be positioned, matched or separated with the material box A that arrives at the material picking station a. In this way, when the grasping portion 31 grasps the material box A in the material bin 10 and drives the material box A to the material picking station a, the positioning mechanism 60 is controlled to be positioned and matched with the material box A, so that the material box A is positioned and fixed at the material picking station a, on the one hand, ensuring that the position accuracy of the material box A meets the design requirements, and on the other hand, avoiding the position deviation of the material box A during the process of the stacking robot taking the material sheet.

[0043] Specifically in the embodiment, the positioning mechanism 60 includes a positioning drive member 61 and a positioning pin 62 connected to the driving end of the positioning drive member 61. A positioning hole capable of being positioned and matched with the positioning pin 62 is provided on each material box A. When the grabbing portion 31 drives the material box A to move from the material bin 10 to the material picking station a, the positioning drive member 61 drives the positioning pin 62 to extend toward the material box A, so that the positioning pin 62 is inserted into the positioning hole on the material box A, thereby preventing the material box A from continuing to move at the material picking station a. After all the sheets in the material box A at the material picking station a are taken away, the positioning drive member 61 drives the positioning pin 62 to retract, so that the positioning pin 62 withdraws from the positioning hole on the empty material box, so that the empty material box located at the material picking station a can return to the material bin 10 under the drive of the grabbing portion 31.

[0044] Furthermore, the number of positioning mechanisms 60 is set to two, and the two positioning mechanisms 60 are respectively located on the opposite sides of the material box A arriving at the material picking station a, so that the two positioning mechanisms 60 respectively position the material box A from both sides of the material box A, ensuring that the positioning of the material box A is more accurate, and further improving the position accuracy of the material box A.

[0045] In the embodiment of the present application, the feeding device further includes a lifting mechanism 40, which includes a lifting drive 41 and a lifting member 42 connected to the driving end of the lifting drive 41. The lifting member 42 is located below the material box A that arrives at the material taking station a. The lifting drive 41 is used to drive the lifting member 42 to move upward, so that the lifting member 42 lifts the material sheet in the material box A that arrives at the material taking station a, so that the stacking robot can accurately absorb the uppermost material sheet in the material box A.

[0046] Further, the lifting member 42 is connected to the support frame 51 in a manner that it can be lifted and moved, the lifting drive member 41 is installed on the support frame 51, and the driving end of the lifting drive member 41 is connected to the lifting member 42, so that the lifting drive member 41 can drive the lifting member 42 to rise or fall relative to the support frame 51. Optionally, the lifting drive member 41 can adopt an electric cylinder. Of course, in other embodiments, the lifting drive member 41 can also adopt other types of linear drive modules, as long as it can drive the lifting member 42 to rise or fall, which is not limited here.

[0047] Optionally, the lifting member 42 is installed on the support frame 51 via guide components such as guide rails or guide rods, so that the movement of the lifting member 42 relative to the support frame 51 is guided by the guide components such as guide rails or guide rods, which is beneficial to improving the movement accuracy of the lifting member 42 when rising or falling.

[0048] It should be noted that, in actual use, after the gripping portion 31 drives the material box A to the material picking station a, the positioning mechanism 60 is used to position the material box A. Then, the stacking robot moves to the top of the material box A located at the material picking station a, and gradually descends until the stacking robot absorbs the topmost sheet of material in the material box A located at the material picking station a. Then, the stacking robot rises, thereby driving the absorbed sheet to rise together. Since the two adjacent layers of sheets in the material box A are attached to each other, there is a certain bonding force between the two. When the stacking robot absorbs the topmost sheet of material and rises, the topmost sheet of material will also rise with the sheet of the next layer, causing the stacking robot to take away two or more sheets of material at a time.

[0049] In order to ensure that the stacking robot only takes away one sheet at a time, in an embodiment of the present application, the loading device also includes an anti-double sheet mechanism (not marked in the figure). The anti-double sheet mechanism includes a mounting frame 71 and an anti-double sheet member 72 mounted on the mounting frame 71. The anti-double sheet member 72 is located above the material box A that reaches the material taking station a. The anti-double sheet member 72 includes a blowing member and / or a brush. In this way, in the process of the stacking robot sucking the sheet and moving upward, the blowing member is used to blow air to the sheet sucked by the stacking robot and / or the brush is used to scrape the sheet sucked by the stacking robot, so that the top sheet is separated from the next sheet, thereby ensuring that the stacking robot can only take away one sheet at a time (that is, it can only take away the top sheet in the material box A).

[0050] Specifically in the embodiment, the position of the mounting frame 71 in the vertical direction is adjustable, so as to adjust the height of the double-expansion prevention member 72 to ensure that the double-expansion prevention effect of the double-expansion prevention member 72 is better.

[0051] Furthermore, the mounting frame 71 is connected to the support frame 51 in a manner that it can be lifted and moved. The double-opening prevention mechanism further includes an adjusting driving member 73 installed on the support frame 51, and the driving end of the adjusting driving member 73 is connected to the mounting frame 71, so that the adjusting driving member 73 can drive the mounting frame 71 to move in the vertical direction (i.e., rise or fall) relative to the support frame 51, that is, to adjust the position of the mounting frame 71 in the vertical direction, thereby achieving the purpose of adjusting the height of the double-opening prevention member 72.

[0052] Optionally, an electric cylinder may be used as the adjusting drive member 73. Of course, in other embodiments, the adjusting drive member 73 may also be other types of linear drive modules, as long as they can drive the mounting frame 71 to move in the vertical direction to adjust the position, which is not limited here.

[0053] Optionally, the mounting frame 71 can be installed on the support frame 51 via guide components such as guide rails or guide columns, so that the movement of the mounting frame 71 relative to the support frame 51 in the vertical direction is guided by the guide components such as guide rails or guide columns, so that the movement accuracy of the mounting frame 71 meets the design requirements.

[0054] Specifically in the embodiment, the support frame 51 has a defective station b for placing a waste collection box B. When the sheet sucked by the stacking robot is a defective sheet, the stacking robot transfers the defective sheet to the waste collection box B located at the defective station b. Optionally, the defective station b is located on the side of the material taking station a away from the silo 10.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
