[0002] After flat printed materials, packaging bags, paper and other sheet materials are produced, they need to go through processes such as stacking, sorting, packaging and bundling before the production process is completed and they can be shipped out of the factory at any time.

[0003] If automated, mechanized stacking, sorting, packaging and bundling of sheet materials are adopted, which involves the conveying and stacking of sheet materials, baffles on both sides are usually set to guide, limit and stack the sheet materials. Especially when several rows of sheet materials are cut at the same time in the previous process, several rows of baffles are needed to guide, limit and stack the sheet materials.

[0004] Existing lateral branch baffles are all arranged above the transmission mechanism. In order not to interfere with the transmission of the transmission mechanism and avoid contact and wear between the lateral branch baffle and the transmission surface of the transmission mechanism, a certain gap needs to be left between the bottom of the lateral branch baffle and the transmission surface. However, since a single sheet of material is very thin, soft and light, the sheet material is easy to drift and deviate from the transmission path during the transmission process, and then leak from the gap between the bottom of the lateral branch baffle and the transmission surface.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described below with reference to the accompanying drawings.

[0031] The sheet material described in the present invention can be sheet materials in various forms such as flat printed matter, packaging bags, paper, etc., all of which are applicable to the present invention.

[0032] The front of the present invention refers to the downstream direction of the sheet material conveyed by the conveying mechanism, and the rear refers to the upstream direction of the sheet material conveyed by the conveying mechanism. The front section of the present invention refers to the section where the side baffle is located downstream of the conveying direction of the conveying mechanism, and the rear section refers to the section where the side baffle is located upstream of the conveying direction of the conveying mechanism.

[0033] Example 1

[0034] The sheet material splitting, transporting and stacking device of Example 1 is as follows Figures 1 to 5 As shown, the branch transmission stacking device includes a transmission mechanism 1 and a side baffle 2, the side baffles 2 are vertically arranged opposite to each other and are parallel to the transmission direction of the transmission mechanism 1; the rear section of the side baffle 2 is a branch baffle section 2a, the branch baffle section 2a is arranged above the transmission mechanism 1 to separate a branch transmission channel, a gap is provided on the transmission surface of the transmission mechanism 1, and the bottom of the branch baffle section 2a extends from the gap of the transmission surface to below the transmission surface; the front section of the side baffle 1 is a stacking baffle section 2b, the stacking baffle section 2b extends out in front of the transmission mechanism 1 and extends downward to separate a stacking groove.

[0035] After the sheet material is guided and limited by the branch baffle section 2a on the transmission mechanism 1, it enters the stacking groove and is limited and stacked by the stacking baffle section 2b. The integrated connection between the branch baffle section 2a and the stacking baffle section 2b facilitates synchronous position adjustment and smooth transportation of the sheet material.

[0036] The side baffle 2 can move perpendicularly to the transmission direction of the transmission mechanism 1 to adjust the width of the branch transmission channel and the stacking slot to accommodate sheet materials of different widths.

[0037] As one of the ways to move the side baffle 2, the branch transmission stacking device further includes a side baffle mounting beam 3 that spans above the transmission mechanism 1 and is perpendicular to the transmission direction of the transmission mechanism 1, and the side baffle 2 is movably mounted on the side baffle mounting beam 3 along the axial direction of the side baffle mounting beam 3. The movement of the side baffle 2 on the side baffle mounting beam 3 can be achieved by a manual or automatic distance adjustment mechanism 4 (such as a gear rack mechanism, etc.).

[0038] There are two side baffle mounting beams 3 , the branch baffle section 2 a is mounted on one side baffle mounting beam 3 , and the stacked baffle section 2 b is mounted on the other side baffle mounting beam 3 .

[0039] Side baffle mounting beam lifting mechanisms 5 are respectively provided at both ends of the side baffle mounting beam 3. Since the bottom of the branch baffle section 2a extends from the gap of the transmission surface to below the transmission surface, when the side baffle 2 is moved, the side baffle mounting beam lifting mechanism 5 can be used to lift the side baffle mounting beam 3 first to avoid the transmission mechanism 1 blocking the side baffle 2.

[0040] By setting up a transmission mechanism 1 with a gap in the transmission surface, the bottom of the branch baffle section 2a is extended from the gap in the transmission surface to below the transmission surface, thereby not interfering with the transmission of the transmission mechanism 1 and not leaving a gap between the bottom of the branch baffle section and the transmission surface, thereby solving the problem of deviation and leakage of sheet materials during transportation.

[0041] The transmission mechanism 1 with a gap on the transmission surface can be designed into a variety of different structures, and the bottom of the branch baffle segment 2a can be designed according to the specific structure of the transmission mechanism so that the bottom of the branch baffle segment 2a extends from the gap on the transmission surface to below the transmission surface. The specific structural scheme of this embodiment is as follows:

[0042] The transmission mechanism 1 is a belt conveyor, which includes a driving roller 6 and a plurality of conveyor belts 7. The conveyor belts 7 pass around the driving roller 6 and are arranged in parallel and spaced apart. The bottom of the branch baffle section 2a extends from the gap between the conveyor belts 7 to below the transmission surface of the conveyor belts 7. A gap on the transmission surface is formed between the parallel and spaced conveyor belts 7, and the bottom of the branch baffle section 2a extends from the gap to below the transmission surface, thereby not interfering with the transmission of the transmission mechanism 1, and not leaving a gap between the bottom of the branch baffle section and the transmission surface, thereby solving the problem of displacement and leakage of sheet materials during the transportation process.

[0043] Since several rows of sheet materials may be cut at the same time in the previous process, and the width and position of the cut sheet materials may change according to the changes in actual production, as mentioned above, the position of the side baffles 2 needs to be adjusted at this time so that the position between the two side baffles 2 is directly opposite to the sheet materials cut and transported from the upstream. However, when adjusting the position of the side baffles 2, if a certain side baffle 2 happens to be required to stay at the position of a certain conveyor belt 7, in order to achieve the purpose of the bottom of the branch baffle section 2a extending below the transmission surface, the conveyor belt 7 needs to give way. Therefore, this embodiment designs a structure for adjusting the conveyor belt to give way, and the specific structure is as follows:

[0044] The transmission mechanism 1 also includes a transmission roller pushing mechanism, which is used to push the transmission roller 6 to move along the axial direction of the transmission roller. The transmission roller 6 moves along the axial direction of the transmission roller, driving the conveyor belt 7 wound around the transmission roller 6 to give way to the left and right.

[0045] The transmission roller pushing mechanism can push the entire transmission roller 6 to move axially, or it can adopt the following structure to only push the roller of the outer layer of the transmission roller to move axially: the transmission roller 6 includes a roller 8 and a rotating shaft 9 which is internally sleeved in the roller 8, and both ends of the rotating shaft 9 are rotatably connected to the transmission roller mounting frame 10, and the roller 8 and the rotating shaft 9 are axially slidingly matched and circumferentially fixedly matched, and the transmission roller pushing mechanism is used to push the roller 8 to move axially relative to the rotating shaft 9.

[0046] As one of the ways to achieve axial sliding fit between the roller 8 and the rotating shaft 9 and circumferential fixed fit, an axial groove 11 is provided on the rotating shaft 9 , and the roller 8 and the rotating shaft 9 are connected by a screw 12 passing through the roller 8 and the axial groove 11 .

[0047] As one of the specific structures of the transmission roller pushing mechanism, the transmission roller pushing mechanism includes a pushing plate 13 and a thrust member for pushing the pushing plate 13 to move axially along the roller 8. The pushing plate 13 cooperates with the roller 8 in a circumferential rotational direction and is fixedly cooperated with the roller 8 in an axial direction.

[0048] As one of the ways for the push plate 13 to rotate with the roller 8 along the circumferential direction of the roller and to be fixedly matched along the axial direction of the roller, push plates 13 are respectively provided at both ends of the roller 8, and the push plates 13 are connected to the ends of the roller 8 through thrust bearings 14.

[0049] As one of the specific structures of the thrust member, the thrust member includes a screw pair 15 and a return spring 16. The screw of the screw pair 15 is arranged along the axial direction of the roller 8. The nut of the screw pair 15 is connected to the push plate 13. The return spring 16 is used to tighten the push plate 13 along the axial direction of the roller 8. When the conveyor belt 7 is adjusted to give way, the screw pair 15 pushes the push plate 13 at one end and the push plate 13 at the other end compresses the return spring 16 to give way to the right, and vice versa when giving way to the left.

[0050] If the transmission mechanism is long, in order to ensure synchronous and uniform pushing of the front and rear ends, there are more than two screw rod pairs 15, and the screw rods of the screw rod pairs 15 are arranged in parallel and synchronously driven by the sprocket 17.

[0051] Example 2

[0052] like Figure 6 As shown, the specific structural design of the bottom of the branch baffle section 2a extending from the gap of the transmission surface to below the transmission surface in this embodiment is as follows: the transmission mechanism 1 is a roller conveyor, and the bottom of the branch baffle section 2a is provided with a convex tooth 18, and the convex tooth 18 is embedded in the gap between the rollers 19. A gap of the transmission surface is formed between the rollers 19, and the convex tooth 18 of the bottom of the branch baffle section 2a is extended from the gap to below the transmission surface, so that the transmission of the transmission mechanism is not interfered, and no gap is left between the bottom of the branch baffle section and the transmission surface, thereby solving the problem of deviation and leakage of sheet materials during the transportation process.

[0053] Of course, this embodiment also needs to set up a stacked baffle segment similar to that of Embodiment 1, and connect the branch baffle segment with the stacked baffle segment as a whole ( Figure 6 not shown).

[0054] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
