[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0027] An embodiment of the present utility model discloses a sheet material supply device, wherein the sheet material can be the instruction manuals of products such as medicines and cosmetics, and the instruction manuals are in a folded state due to their large size. The sheet material supply device of this embodiment can disperse and convey the instruction manuals stacked together one by one, thereby overcoming the problems of misalignment and wrinkling of the instruction manuals caused by the material rubbing method in the prior art.

[0028] As Figure 1 shown, the sheet material supply device of this embodiment includes: a separating mechanism 10, a conveying mechanism 20, a supply mechanism 30, and a guiding mechanism 40.

[0029] The separating mechanism 10 is used to pick up the instruction manuals from the stacked ones one by one and place them on the conveying mechanism 20 on one side to achieve the dispersed and one-by-one conveying of the instruction manuals. In this embodiment, the separating mechanism 10 can be set in two groups. With such a setting, when one group of the separating mechanisms 10 stops operating, the other group of the separating mechanisms 10 can continue to supply materials, which is beneficial to ensuring the continuity of the sheet material supply and avoiding the problem of material shortage affecting the downstream packaging of the instruction manuals. When the separating mechanism 10 is set in two groups, the two are arranged at intervals on one side of the conveying mechanism 20 in the conveying direction.

[0030] Among them, the separating mechanism 10 includes: a working head 11 and a turnover unit 12. The working head 11 is used to provide the acting force for sheet material separation, so as to realize the picking up of the stacked sheet materials. The working head 11 is connected to the turnover unit 12. When the turnover unit 12 works, it can drive the working head 11 to perform reciprocating feeding motion, so as to turnover the picked-up sheet materials onto the conveying mechanism 20.

[0031] As Figure 2 、 3 shown, in one embodiment, the working head 11 is a suction cup, and the suction cup is arranged on a base 111. At this time, the working head 11 picks up the topmost layer of the instruction manual through the action of vacuum adsorption. The turnover unit 12 includes: a rotating motor 121 and a rotating arm 122. At this time, one end of the rotating arm 122 is in transmission connection with the rotating motor 121, and the other end is connected to the base 111 of the suction cup. In this way, when the rotating motor 121 works, it can drive the suction cup to perform pivoting reciprocating feeding motion through the rotating arm 122.

[0032] When the working head 11 performs a pivotal reciprocating feeding motion, the working head 11 needs to be able to perform synchronous self-rotation so as to facilitate the adjustment of the picking angle. To achieve the synchronous self-rotation of the working head 11, the base 111 of the suction cup is connected to the rotating arm 122 through a rotating shaft. At the same time, the sheet separating mechanism 10 further includes: a driving wheel 13, a driven wheel 14, and a transmission belt 15; the driving wheel 13 is installed on the motor shaft of the rotating motor 121, the driven wheel 14 is installed on the rotating shaft, and the transmission belt 15 is sleeved on the driving wheel 13 and the driven wheel 14. Thus, when the rotating motor 121 works, it can drive the driving pulley to rotate synchronously, and the driving pulley further drives the driven wheel 14 to perform linkage through the transmission belt 15, and the driven wheel 14 then drives the working head 11 to perform synchronous self-rotation to achieve the adjustment of the picking angle.

[0033] Again, as Figure 1 shown, in order to provide a sheet material suitable for the sheet separating mechanism 10 to pick up, the sheet material supply device further includes: a magazine 51, a magazine conveying line 52, and a pushing cylinder 53. When the sheet separating mechanism 10 is provided in two groups, the magazine 51, the magazine conveying line 52, and the pushing cylinder 53 are also provided in two groups.

[0034] Specifically, the magazine 51 contains the manuals stacked together, the magazine conveying line 52 is arranged on one side of the sheet separating mechanism 10, and several magazines 51 are located on the magazine conveying line 52. Thus, the magazine 51 can move along the magazine conveying line 52 to one side of the sheet separating mechanism 10. In order to further move the magazine 51 to the picking position, the pushing cylinder 53 is arranged perpendicular to the magazine conveying line 52, and it can push the magazine 51 to the picking position when the magazine 51 moves to the downstream end of the magazine conveying line 52 so as to facilitate the working head 11 to pick up the manuals.

[0035] Considering that the height of the manuals stacked in the magazine 51 gradually decreases as the picking progresses, in order to keep the stacked manuals at a height suitable for picking, the sheet material supply device further includes a lifting cylinder 54. The lifting cylinder 54 is located below the picking position, and a hollow groove is provided at the bottom of any magazine 51. When the magazine 51 rotates to the picking position, the lifting cylinder 54 can extend into the corresponding magazine 51 through the hollow groove. Thus, the lifting cylinder 54 can continuously push the manuals in the magazine 51 to a height suitable for picking.

[0036] The conveying mechanism 20 can receive the sheet materials transferred by the sheet separating mechanism 10 to cooperate with the sheet separating mechanism 10 to achieve the scattered and one-by-one conveying of the manuals stacked together. Specifically, the conveying mechanism 20 includes a first conveying line. At this time, one end of the first conveying line is arranged close to the sheet separating mechanism 10, and the other end is arranged close to the supply mechanism 30. Thus, the manuals on the first conveying line are scattered and conveyed to the supply mechanism 30 one by one. In one embodiment, the first conveying line includes a first conveyor belt.

[0037] The supply mechanism 30 can supply and send out the sheet material from the conveying mechanism 20. Specifically, the supply mechanism 30 includes a second conveying line. At this time, one end of the second conveying line is docked with the conveying mechanism 20, and the other end forms a supply and sending end. Thus, the instruction manuals are circulated one by one dispersedly from the supply and sending end to the downstream workstations.

[0038] As Figure 4 shown, in order to be able to control the transmission of the instruction manuals, the second conveying line includes: a second conveyor belt 31 and a third conveyor belt 32. Among them, the second conveyor belt 31 and the third conveyor belt 32 are arranged opposite to each other up and down, and the distance between the two is equivalent to the thickness of a folded instruction manual, so as to form a space suitable for the transmission of the instruction manuals. At the same time, the second conveyor belt 31 and the third conveyor belt 32 are arranged obliquely in the feeding direction, so as to facilitate the circulation of the instruction manuals from the supply and sending end to the downstream workstations.

[0039] In one embodiment, both the second conveyor belt 31 and the third conveyor belt 32 are conveyor rubber bands; there are two second conveyor belts 31, and one end of the two second conveyor belts 31 is sleeved on the second double-groove pulley, and the rest are respectively sleeved on a number of second tensioning pulleys. A number of second tensioning pulleys are fixed between the two vertical plates 33 through the axle. There are two third conveyor belts 32, and one end of the two third conveyor belts 32 is sleeved on the third double-groove pulley, and the rest are respectively sleeved on a number of third tensioning pulleys. A number of third tensioning pulleys are fixed between the two vertical plates 33 through the axle. Thus, by setting the second conveyor belt 31 and the third conveyor belt 32 as conveyor rubber bands, it is beneficial to simplify the structure of the second conveying line.

[0040] Again as Figure 2 shown, the guiding mechanism 40 is used to assist the instruction manuals to enter the supply mechanism 30 from the conveying mechanism 20. Specifically, the guiding mechanism 40 includes: a guiding wheel 41 and a third conveying line 42; one end of the third conveying line 42 is docked with the downstream end of the first conveying line, and the other end is docked with the upstream end of the second conveying line; the guiding wheel 41 is located above the other end of the third conveying line 42. Thus, the instruction manuals are conveyed one by one dispersedly to the supply mechanism 30 through the third conveying line 42.

[0041] In summary, the utility model turns the sheet material one by one to the conveying mechanism through the sheet separating mechanism, and then turns it to the supply mechanism for discharging. In this way, the sheet material is conveyed one by one dispersedly, thus overcoming the problems of misalignment and wrinkling of the instruction manuals caused by the material rubbing method in the prior art. In addition, the utility model is also provided with two groups of sheet separating mechanisms, and the two groups can work independently. Thus, when one group of sheet separating mechanisms stops, the other group of sheet separating mechanisms can continue to supply materials, which is beneficial to ensuring the continuity of the sheet material supply.
