[0041] This utility model provides a material feeding device, such as... Figures 1-7 As shown.

[0042] The first conveying mechanism 20a is disposed on one side of the conveyor line 30 and can convey materials onto the conveyor line 30; the second conveying mechanism 20b is disposed opposite to the first conveying mechanism 20a and is located on the other side of the conveyor line 30, and can convey materials onto the conveyor line 30.

[0043] The first paper-taking mechanism 10a is located on the feed side or discharge side of the conveyor line 30. The first paper-taking mechanism 10a and the first conveying mechanism 20a are arranged adjacent to each other along the conveying direction of the conveyor line 30. The second paper-taking mechanism 10b is located on the same side of the conveyor line 30 as the first paper-taking mechanism 10a. The second paper-taking mechanism 10b and the second conveying mechanism 20b are arranged adjacent to each other along the conveying direction of the conveyor line 30.

[0044] As shown in the figure Figure 1 and Figure 2 As shown, the first paper feeding mechanism 10a is located on the feed side of the conveyor line 30.

[0045] The first conveying mechanism 20a, the second conveying mechanism 20b and the conveyor line 30 are arranged in the transverse direction M1, and the first paper picking mechanism 10a and the second paper picking mechanism 10b are arranged in the longitudinal direction M2. The layout of the material feeding device is more compact, reducing the floor space occupied by the feeding device.

[0046] The first conveying mechanism 20a and the second conveying mechanism 20b can feed materials alternately at the same time. While feeding materials from both sides, the two paper picking mechanisms arranged along the longitudinal direction M2 can pick up paper simultaneously. That is, the first paper picking mechanism 10a can pick up paper in cooperation with the first conveying mechanism 20a, and the second paper picking mechanism 10b can pick up paper in cooperation with the second conveying mechanism 20b, so as to achieve material change without stopping the machine and greatly improve production efficiency.

[0047] The material feeding device also includes a first feeding station 40a and a second feeding station 40b. The first feeding station 40a is located on one side of the conveyor line 30 and is located below the first handling mechanism 20a.

[0048] The second feeding station 40b is located on the other side of the conveyor line 30, and is located below the second handling mechanism 20b.

[0049] The first feeding station 40a and the first conveying mechanism 20a are arranged at intervals along the vertical direction M3, and the second feeding station 40b and the second conveying mechanism 20b are arranged at intervals along the vertical direction M3, making the material feeding device more compact.

[0050] In addition, the material supplied at the first feeding station 40a can be glass, sheet metal or other materials. This utility model does not limit the type of material. The following uses glass as an example to illustrate this technical solution.

[0051] The initial material arrival state is that photovoltaic glass is stacked on a pallet, with a paper 1 between two photovoltaic glass pieces. The pallet and the glass and paper 1 stacked on it are placed at the first material supply station 40a, and the same material is placed at the second material supply station 40b.

[0052] When the first feeding station 40a needs to change materials, this utility model can pause the operation of the first conveying mechanism 20a and the first paper picking mechanism 10a. After changing the materials at the first feeding station 40a, the operation of the first conveying mechanism 20a and the first paper picking mechanism can be restarted. During this process, the second conveying mechanism 20b and the second picking mechanism continue to operate normally, supplying glass to the conveyor line 30. This achieves material change without stopping the machine, which can significantly improve production efficiency.

[0053] The material feeding device also includes a gantry frame. The top beam 51 of the gantry frame is located above the conveyor line 30. Two first guide rails 52 are installed on the top beam 51. The length direction of the first guide rails 52 is perpendicular to the conveying direction of the conveyor line 30. The first handling mechanism 20a and the second handling mechanism 20b are slidably installed on the first guide rails 52.

[0054] The first conveying mechanism 20a includes a base plate 21, a first motor 22, a first column 23, a frame 24, and a second motor 25. A slider is provided at the bottom of the base plate 21, and the base plate 21 slides in cooperation with the first guide rail 52.

[0055] The first motor 22 is fixed to the base plate 21. The transmission shaft of the first motor 22 meshes with the first rack 53 on the inner side of the first guide rail 52. The first motor 22 drives the base plate 21 to slide along the length direction of the first guide rail 52.

[0056] The first column 23 and the gantry frame slide in a vertical M3 manner, and a second rack 231 is provided on the side of the first column 23; the frame 24 is fixed to the lower end of the first column 23, and a number of suction cups 241 are provided at the bottom of the frame 24.

[0057] The second motor 25 is fixed to the base plate 21. The drive shaft of the second motor 25 meshes with the second rack 231 on the first column 23. The second motor 25 drives the frame 24 to move up and down vertically along M3.

[0058] The working process of the first handling mechanism 20a is described below.

[0059] First, the AGV trolley transports the pallet and the glass plates stacked on it to the first feeding station 40a. The photoelectric sensor detects the glass stacking signal. The frame 24 descends vertically along M3 via a gear rack. Several suction cups 241 on the frame 24 adhere to the glass surface. The negative pressure value of the suction cups 241 is detected to be normal.

[0060] Then, the frame 24 rises vertically along M3 to the set height, and the frame 24 moves horizontally to the right via the gear rack M1 to the top of the conveyor line 30. Once in place, the frame 24 descends vertically along M3 to the set height, the vacuum solenoid valve switches direction, and the glass is placed on the conveyor line 30, completing the glass loading process.

[0061] Finally, frame 24 returns to the reference point and begins loading the next piece of glass.

[0062] The following describes the specific structure and working process of the first paper-taking mechanism 10a.

[0066] The third motor 14 is fixed to the lifting plate 111. The third motor 14 is connected to the pulley transmission unit. The third motor 14 drives the paper picking arm 12 and the paper clamping unit 13's gripper 131 and crossbeam 132 to slide longitudinally M2 respectively through the pulley transmission unit.

[0067] like Figure 5 and 6 As shown, the belt drive unit includes a driving pulley 61, a first driven pulley 62, a second driven pulley 63, and a first synchronous belt 64. The driving pulley is connected to the shaft of the third motor 14.

[0068] The first driven wheel 62 is rotatably connected to the inner end of the paper-taking arm 12; the second driven wheel 63 is rotatably connected to the inner end of the paper-taking arm 12, and the first driven wheel 62 and the second driven wheel 63 are respectively placed on both sides of the axial direction of the driving wheel 61;

[0069] One end of the first synchronous belt 64 is fixed to the inner end of the paper-taking arm 12, and the other end is fixed to the outer end of the paper-taking arm 12. The first synchronous belt 64 is sequentially wound around the first driven wheel 62, the driving wheel 61, and the first driven wheel 63 from the inner end of the paper-taking arm 12.

[0070] like Figure 5 and 7 As shown, the belt drive unit also includes a first pulley 66, a second pulley 67, and a second synchronous belt 65. The first pulley 66 is rotatably connected to the inner end of the paper-taking arm 12; the second pulley 67 is rotatably connected to the outer end of the paper-taking arm 12.

[0071] The second synchronous belt 65 is wound around the first pulley 66 and the second pulley 67. The transmission direction of the second synchronous belt 65 is consistent with the movement direction of the paper-taking arm 12. The upper belt body 651 of the second synchronous belt 65 is fixed to the lifting plate 111, and the lower belt body 652 of the second synchronous belt 65 is fixed to the crossbeam 132. The second synchronous belt 65 drives the crossbeam 132 to move along the longitudinal direction M2.

[0072] The lifting unit 11 includes a vertical guide rail 112, a second column 113 and a lifting motor 114, with the vertical guide rail 112 fixed to the frame 3;

[0076] After the first conveying mechanism 20a picks up the glass, as the first conveying mechanism 20a rises vertically along M3, the first paper picking mechanism 10a begins to work. The working process of the first paper picking mechanism 10a is as follows.

[0077] First, the lifting motor 114 drives the lifting plate 111 and the crossbeam 132 of the paper clamping unit 13 to rise vertically along M3 to the corresponding height. The paper picking arm 12 moves the crossbeam 132 to 2 / 3 of the paper length along longitudinally along M2 through the pulley transmission unit.

[0078] Then, the lifting motor 114 drives the paper-picking arm 12 to lower the grippers 131 on the crossbeam 132 to the designated height. The two grippers 131 on the crossbeam 132 pick up the paper. After the paper is picked up, the entire paper-picking arm 12 returns to the top of the paper-picking trolley 2 through the pulley transmission unit, and the two grippers 131 release the paper.

[0079] Finally, the paper-fetching arm 12 returns to the reference point, waiting for the next paper fetch.
