[0051] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0052] See also Figures 1-16 A feeding mechanism of a flat-mouth machine includes a bracket body 1, a positioning unit, a first grabbing unit 2 and a second grabbing unit 3.

[0053] The bracket body 1 can be used as a support and component installation tool and can stand independently on the ground, or directly installed on the flat machine housing 41, such as Figure 1 、 Figure 2 The figure shows a schematic diagram of the bracket body 1 being fixedly installed on the flat-mouth machine casing 41.

[0054] The bracket body 1 has a first platform 11 and a second platform 12, wherein the first platform 11 is used to transport stacked materials to a designated position and support the stacked materials, and after arriving at the designated position, it is positioned by the first positioning member of the positioning unit; the second platform 12 is used to transport a single material to a designated position and support the single material, and after arriving at the designated position, it is positioned by the second positioning member 65 of the positioning unit.

[0055] In this embodiment, the first platform 11 includes a first active roller, a first driven roller, and a first conveyor belt wound around the first active roller and the first driven roller, and the first active roller is connected to the first motor arranged on the bracket body 1; the second platform 12 includes a second active roller, a second driven roller, and a second conveyor belt wound around the second active roller and the second driven roller, and the second active roller is connected to the second motor arranged on the bracket body. The specific transmission structure through the coordination of the active roller, the driven roller, the conveyor belt and the motor can refer to the existing design and will not be elaborated on.

[0056] Rely on the corresponding conveyor belt to move the materials to the designated location.

[0057] In order to make the stacked materials or single materials move forward more stably, in this embodiment, the first platform 11 and / or the second platform 12 are provided with a limiter for limiting the width of the material moving channel, such as Figure 1-3 As shown, the limiting member includes a first limiting strip 51 and a second limiting strip 52 , and the first limiting strip 51 and the second limiting strip 52 are respectively positioned on the bracket body 1 through a plurality of fixing blocks 53 .

[0058] The first positioning member and the second positioning member are both installed on the bracket body 1 , wherein the first positioning member is located above the first platform 11 , and the second positioning member is located above the second platform 12 .

[0059] In order to better adapt to the flat-edge machine, in this embodiment, the first platform 11 and the second platform 12 are set to have a certain height difference between each other, such as Figure 1 、 Figure 2 As shown, the first platform 11 is located on one side of the flattening machine and is in a lower position; the second platform 12 is located above the flattening machine and is in a higher position. Of course, other position layouts can also be selected according to actual needs.

[0060] In this embodiment, the first positioning member includes at least two clamping units and cylinders 61 for driving the corresponding clamping units to move laterally. Figure 4 As shown, the cylinder 61 is fixed on the bracket body 1, and the clamping unit includes a clamping plate 62 and a material dividing piece 63 arranged on the clamping plate 62. The material dividing piece 63 includes a plurality of convex teeth 631. The convex teeth 631 form a certain resistance to the edge of the material so that the grasping piece can automatically separate the adjacent materials from each other when grasping the material, thereby avoiding multiple materials being grasped at the same time and causing the material below to fall and be damaged.

[0061] As one of the embodiments, the material dividing member 63 is arranged obliquely on the clamping plate 62 to improve the material dividing effect. In order to achieve the angle adjustment of the material dividing member 63, in this embodiment, the clamping plate 62 is provided with a notch 621 for accommodating the material dividing member 63 and a plurality of mounting holes 622 connected to the notch 621. The notch 621 can be formed in the form of a longitudinal opening from the top of the clamping plate 62 downward, and the mounting holes 622 are formed in the form of a transverse opening by the side wall of the clamping plate 62, such as Figure 5 shown.

[0062] The material dividing member 63 includes a through hole 632 corresponding to the mounting hole 622. Figure 6 As shown, a pin is arranged at the mounting hole 622, and the pin passes through the through hole 632 accordingly, so that the material dividing piece 63 can rotate along the pin. At the same time, the pin can also limit the material dividing piece 63 to avoid the overall position deviation of the material dividing piece 63.

[0063] In order to facilitate the adjustment of the angle of the material dividing member 63, the material dividing member 63 includes a groove 633, and the clamping plate 62 is fixed with a fixing member 64, such as Figure 5 、 Figure 7 As shown, the fixing member 64 includes a through hole 641 corresponding to the groove body 633, and an adjusting pin is arranged at the through hole 641. One end of the adjusting pin is assembled in the groove body 633. The angle of the dividing member 63 can be adjusted by pushing the adjusting pin. As one of the options, the aperture of the groove body 633 is larger than the aperture of the through hole 641 to provide the required space for the adjusting pin to move after the angle of the dividing member is adjusted; there can be a certain friction resistance between the dividing member 63 and the notch 621, or there can be an interference fit relationship between the two, so as to effectively position the dividing member 63 after the angle is adjusted.

[0064] As for the second positioning member 65, it is used for positioning a single material, and the structure can be simplified accordingly, such as Figure 1 、 Figure 2 and Figure 9 As shown, the second positioning member 65 is fixed on the bracket body 1 and includes a notch 651 adapted to the material. A buffer member 652 , such as a rubber gasket, can be installed at the notch 651 .

[0065] As for how to grab the material on the first platform 11 and transfer it to the second platform 12, in this embodiment, it is achieved by the first grabbing unit 2, which includes a first grabbing member 21 and a first driving unit for driving the first grabbing member 21 to move longitudinally and / or transversely.

[0066] Specifically, the first grabbing member 21 is a suction cup, and the first driving unit includes a first cylinder 22 mounted on the bracket body 1 for controlling the lateral movement of the first grabbing member 21, a slider 24 connected to the first cylinder 22 and sliding on the slide rail 23, and a second cylinder 25 mounted on the slider 24 for controlling the longitudinal movement of the first grabbing member 21. The first grabbing member 21 is mounted at the output end of the second cylinder 25, and the slide rail 23 is fixed on the bracket body 1. Figure 1 、 Figure 2 and Figure 8 As shown, the longitudinal movement of the first grabbing member 21 is achieved by the action of the second cylinder 25, and the synchronous lateral movement of the second cylinder 25 and the first grabbing member 21 is achieved by the action of the first cylinder 22, thereby realizing the transfer of materials from the first platform 11 to the second platform 12 with a height difference.

[0067] When the single material stops at the second positioning member 65, the second gripping unit 3 is activated to transfer it to the corresponding position of the flattening machine.

[0068] When the material is on the second platform 12, its position state is as follows Figure 1 As shown, this state is a horizontal placement state, and the material on the flattening machine needs to be rotated 90 degrees or close to 90 degrees based on the horizontal placement state and loaded into an upright state, and loaded into the placement part 92 of the flattening machine. The placement part 92 has a cavity for accommodating the material so that the edge of the material is at the outer end, and then the rough material of the flattened material edge is turned by the processing head. The action here is realized by the second gripping unit 3.

[0069] Specifically, the second grabbing unit 3 includes a frame 31 with a track, a second grabbing member 32 movable on the track, and a second driving unit 33 for driving the second grabbing member 32 to move. The frame 31 can be fixedly installed on the bracket body 1 or directly fixedly installed on the flat-mouth machine casing 41.

[0070] like Figure 10 、 Figure 11 As shown, the track includes a first track 34 for the second grabbing member 32 to move longitudinally, a second track 35 for the second grabbing member 32 to move from the first position to the second position, and a third track 36 for the second grabbing member 32 to move laterally.

[0071] The first track 34 is used for the second grabbing member 32 to reach down and grab the material. It is a straight track opened longitudinally; the second track 35 is an arc track connecting the first track 34 and the third track 36; the third track 36 is a straight track opened transversely, used for loading the material into the flattening machine installation position in a transverse manner. If there is no track there, it is difficult to load it directly using only the arc track or it will get stuck when loaded.

[0072] As for the second grabbing member 32 , it has components adapted to the special-shaped track so that it can complete the corresponding action without other thrust.

[0073] like Figure 11-14 As shown, in this embodiment, the second grabbing member 32 includes a first arm 321 transmission-connected to the second driving unit 33, a positioning pin 322 disposed on the track, a second arm rotatably disposed on the frame 31, and a suction cup mounted on the second arm.

[0074] The second driving unit 33 can be a motor, which can be fixedly installed on the back of the frame 31. Its output shaft passes through the frame 31 and is connected to the first arm 321 located on the front of the frame 31. The first arm 321 includes a movable slot 3211, which is a through hole.

[0075] The positioning pin 322 includes a first portion 3221 disposed on the track and matched with the movable slot 3211 and a second portion 3222 connected to the second arm. Figure 11 and Figure 13 As shown, the first part 3221 of the positioning pin 322 is not only located at the track and forms a matching relationship with the track, but also forms a matching relationship with the movable groove 3211 and is penetrated through the movable groove 3211. When the first arm 321 is driven to rotate by the second driving unit 33, the positioning pin 322 moves accordingly within the range of the movable groove 3211.

[0076] The second arm 39 is provided with a first slide rail 38 and a second arm 39 arranged on the first slide rail 38, wherein the first slide rail 38 includes a hole 381, which cooperates with the second portion 3222 of the positioning pin 322, and the second portion 3222 of the positioning pin 322 is inserted into the hole 381. Thus, in the process of the first arm 321 driving the positioning pin 322 to move, the first slide rail 38 and the second arm 39 can be driven to move accordingly, which is specifically manifested in the first rail 34 and the third rail 36. On the linear rail, the positioning pin 322 moves linearly, and combined with the first slide rail 38 slidingly arranged on the first arm 37, it can move linearly accordingly, thereby realizing downward exploration to grab materials on the first rail 34, and realizing horizontal loading of materials into the flat-mouth machine placement portion 92 with a cavity on the third rail 36 without the need for auxiliary tools.

[0077] Similar to the first grabbing member 21 , a suction cup is mounted on the second arm 39 .

[0078] As one option, a connecting member 310 is fixed on the first slide rail 38, and the second arm 39 is fixed on the connecting member 310. Figure 11 、 Figure 13 and Figure 14 shown.

[0079] In this embodiment, sensors can be set correspondingly at the action points of each action component, and the sensors transmit signals to the control unit, which is controlled by the control unit. The electrical methods of the sensors and control units can refer to existing designs.

[0080] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
