[0042] Example:

[0043] See also Figures 1 to 8 The spacer paper feeding device in the preferred embodiment of the utility model includes a spacer paper box 1, a suction cup module 5, a moving module and a flipping drive module 8, wherein the suction cup module 5 is arranged above the spacer paper box 1 and is connected to the moving module, so that the suction cup module 5 is driven by the moving module to move relative to the spacer paper box 1, and the spacer paper 3 in the spacer paper box 1 is adsorbed and fed, and the suction cup module 5 is driven by the flipping drive module 8 to flip up and down, so as to adsorb the middle protrusion of the spacer paper 3 and separate it from other spacers.

[0044] Specifically, Figure 4 As shown in the figure, the suction cup module 5 includes a first suction cup 51 and a second suction cup 52 arranged horizontally at an interval, so as to adsorb the separation paper 3 through the two suction cups; at the same time, the first suction cup 51 and the second suction cup 52 are respectively connected to the flipping drive module 8, and a rotating shaft 7 is respectively provided on the inner sides of the first suction cup 51 and the second suction cup 52 facing each other. The first suction cup 51 and the second suction cup 52 are flipped up and down around their respective corresponding rotating shafts 7 under the drive of the flipping drive module 8.

[0045] In actual operation, after the suction cup module 5 absorbs the separator 3, the flip driving module 8 drives the first suction cup 51 and the second suction cup 52 to rotate downward to form a certain angle, thereby forcing the absorbed separator 3 to bulge in the middle and press down on both sides, thereby separating the absorbed separator 3 from the unabsorbed separator 3 below, and forming a certain space between the two, reducing the influence of the absorbed separator 3 on the unabsorbed separator 3 below, and reducing the stacking rate of the separator 3. When the absorption is completed, the two suction cups flip upward to return to their original positions for the subsequent placement of the absorbed separator 3.

[0046] There are many structural forms in which the first suction cup 51 and the second suction cup 52 are turned upside down around their respective corresponding rotating axes 7 under the drive of the turning drive module 8 to separate the adsorbed spacer paper 3 from the unadsorbed spacer paper 3 below, including but not limited to the two specific embodiments described below.

[0047] As one of the specific embodiments, Figure 4As shown in , the paper feed device further includes a mounting seat 6, one end of which is connected to the mobile module, and the other end is rotatably connected to the first suction cup 51 and the second suction cup 52 respectively through a rotating shaft 7. At the same time, the flip drive module 8 includes a first telescopic cylinder 81 and a second telescopic cylinder 82, one end of the first telescopic cylinder 81 is connected to the mounting seat 6, and the other end is rotatably connected to the side of the first suction cup 51 away from the paper feed box 1, and is further preferably connected to the side of the first suction cup 51 away from the second suction cup 52, so as to push the first suction cup 51 to rotate around the rotating shaft 7 through the telescopic movement of the first telescopic cylinder 81; one end of the second telescopic cylinder 82 is connected to the mounting seat 6, and the other end is rotatably connected to the side of the second suction cup 52 away from the paper feed box 1, and is further preferably connected to the side of the second suction cup 52 away from the first suction cup 51, so as to push the second suction cup 52 to rotate around the rotating shaft 7 through the telescopic movement of the second telescopic cylinder 82.

[0048] As another specific embodiment, Figure 5 and Figure 6 As shown in the figure, the flipping drive module 8 includes a first motor 83 and a second motor 85, and the output shafts of the first motor 83 and the second motor 85 are respectively used as the rotating shaft 7 of the first suction cup 51 and the second suction cup 52; at the same time, the output shaft of the first motor 83 is connected to the side of the first suction cup 51 away from the paper separation box 4 through the first adapter 84, and the output shaft of the second motor 85 is connected to the side of the second suction cup 52 away from the paper separation box 4 through the second adapter 86, thereby realizing the up and down flipping of the first suction cup 51 and the second suction cup 52 around the rotating shaft 7 through the rotation of the first motor 83 and the second motor 85.

[0049] Preferably, the first suction cup 51 includes a first suction plate 511 and at least one first suction nozzle 512 arranged on the first suction plate 511, and the suction end of the first suction nozzle 512 is arranged on the side of the first suction plate 511 close to the partition paper box 1, so as to adsorb the partition paper 3 through the first suction nozzle 512; accordingly, the second suction cup 52 includes a second suction plate 521 and a second suction nozzle 522 arranged on the second suction plate 521, and the suction end of the second suction nozzle 522 is arranged on the side of the second suction plate 521 close to the partition paper box 1, so as to adsorb the partition paper 3 through the second suction nozzle 522.

[0050] like Figure 4 In the preferred embodiment shown, two first suction nozzles 512 are spaced apart on the first suction plate 511, and two second suction nozzles 522 are spaced apart on the second suction plate 521, and then a suction nozzle is arranged at each of the four corners of the suction cup module 5 to ensure the reliability of adsorption of the separation paper 3.

[0051] Furthermore, if Figure 1 and Figure 2As shown in the figure, the paper separator material box 1 in the preferred embodiment includes a tray 11, the shape of the tray 11 is adapted to the shape of the paper separator 3, and the size of the tray 11 is slightly larger than the size of the paper separator 3, so as to facilitate the taking and placing of the paper separator 3. A plurality of retaining edges 12 are arranged around the circumference of the tray 11, so as to limit and block the paper separator 3 stored in the tray 11 through the retaining edges 12, so as to prevent the unabsorbed paper separator 3 from leaving the paper separator material box 1, and further separate the absorbed paper separator 3 from the unabsorbed paper separator 3.

[0052] Specifically, Figure 2 and Figure 3 As shown in the figure, the retaining edge 12 includes a supporting portion 121 and at least one bending portion 122; wherein, one end of the supporting portion 121 is fixedly connected to the base, and the other end is connected to at least one bending portion 122; accordingly, the other end of the bending portion 122 is suspended in the air and bent toward the side close to the tray 11, forming a certain angle with the supporting portion 121, thereby blocking the partition paper 3 in the partition paper box 1.

[0053] like Figure 2 In the preferred embodiment shown, a guard 12 is provided on each side of the tray 11, and the support portion 121 is U-shaped to facilitate the placement and removal of spacer paper, and is arranged vertically perpendicular to the tray 11, with one end fixedly connected to the outer side of the edge of the tray 11, and the other end connected to two separately arranged bending portions 122.

[0054] Preferably, a lifting module 2 is also provided at the bottom of the spacer paper material box 1, and the lifting module 2 can drive the tray 11 to move up and down, so that during the process of taking the spacer paper 3, the height of the tray 11 can be adjusted by the lifting module 2, so that each time the suction cup module 5 takes the material, the top layer of spacer paper 3 is always at the same height, which is convenient for the suction cup module 5 to adsorb and grasp.

[0055] Preferably, a plurality of blowing nozzles 4 are arranged along the circumferential direction of the outer circumference of the separator paper box 1. The blowing nozzles 4 are fixed on the base, and the output direction of the blowing nozzles 4 faces the separator paper 3 so as to evenly blow the separator paper 3 and avoid adhesion between the upper and lower layers of separator paper 3.

[0056] Furthermore, if Figure 1 As shown in the figure, the suction cup module 5 in the preferred embodiment is connected to the movable module, so that the movable module drives the suction cup module 5 to perform horizontal and vertical lifting movements, thereby driving the suction cup module 5 to move to the top of the paper separation material box 1, to adsorb the paper separation 3 in the paper separation material box 1, and to load the paper separation 3 after adsorbing the paper separation 3.

[0057] Furthermore, the mobile module in the preferred embodiment includes a transverse movement unit 9 and an upper and lower material taking unit 10, wherein one end of the upper and lower material taking unit 10 is connected to the transverse movement unit 9, and the other end is connected to the suction cup module 5, so that the suction cup module 5 can move up and down under the drive of the upper and lower material taking unit 10, and can move horizontally under the drive of the transverse movement unit 9. More specifically, as Figure 4 In the illustrated embodiment, the traverse unit 9 is connected to the mounting seat 6 .

[0058] In actual setting, the traverse module can be selected as any one of the linear motion modules such as a screw module, a belt module, etc.

[0059] Further, taking the flip driving module 8 including the first telescopic cylinder 81 and the second telescopic cylinder 82 as an example, the specific working process of the paper spacer feeding device is as follows:

[0060] (1) The lifting module 2 lifts the tray 11 to a height where the topmost layer of paper 3 in the paper box 1 is at a height where the suction cup module can suck and take out the material;

[0061] (2) The blowing nozzle 4 blows air to evenly disperse the separator paper 3, and the upper and lower material taking units 10 drive the suction cup module 5 to move downward until the first suction cup 51 and the second suction cup 52 contact and absorb the uppermost layer of separator paper 3;

[0062] (3) The first telescopic cylinder 81 and the second telescopic cylinder 82 extend to push the first suction cup 51 and the second suction cup 52 to flip downward around the rotation axis 7.

[0063] It can be understood that when the first suction cup 51 and the second suction cup 52 are turned downward, the middle of the absorbed separator 3 is forced to bulge, and the edges on both sides press the unabsorbed separator 3 below downward. Figure 7 As shown in , the uppermost adsorbed separator paper 3 is further separated from the lower unadsorbed separator paper 3, thereby reducing the influence of the upper adsorbed separator paper 3 on the lower unadsorbed separator paper 3.

[0064] (4) The upper and lower material taking units 10 drive the suction cup module 5 and the adsorbed separator paper 3 to move upward. Figure 8 As shown in the figure, the adsorbed separator paper 3 is transported to the specified position by the lateral movement unit 9 to complete the loading of the separator paper 3.

[0065] It can be understood that when the adsorbed spacer paper 3 moves upward with the suction cup module 5, the spacer paper 3 below it that is not adsorbed loses the pressing effect of the adsorbed spacer paper 3 above it, and at the same time, under the influence of other factors such as the rising air flow of the adsorbed spacer paper 3, it moves upward for a certain distance. It can be blocked by the retaining edges 12 around the spacer paper box 1, so that it cannot separate from the spacer paper box 1 and finally returns to the bottom of the spacer paper box 1 under the action of gravity.

[0066] The paper separator feeding device in the utility model has a simple and reliable structure and an ingenious design. It can effectively reduce the interaction between paper separators, reduce the stacking rate of feeding, effectively reduce the failure rate of equipment operation, ensure stable feeding, reduce resource waste, and reduce costs. It has good application prospects and promotion value.

[0067] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
