[0021] like Figure 1-Figure 3 The automatic feeding device of a leather folding machine shown comprises: a feeding robot 1 and a feeding structure.

[0022] like Figure 1 and Figure 2 As shown, the feeding manipulator 1 is a multi-degree-of-freedom manipulator, and a suction nozzle 2 is provided on the feeding manipulator 1. The feeding manipulator 1 used is an existing product, and those skilled in the art can select the required model and specifications according to actual needs.

[0023] The feeding robot 1 in this scheme has two degrees of freedom: horizontal movement and up and down movement. When the suction nozzle 2 is connected to an external negative pressure device, negative pressure can be generated inside the suction nozzle 2. The feeding robot 1 moves up and down to absorb the material, and then moves horizontally to send the material to the processing equipment for processing.

[0024] The feeding structure includes a bracket 3, a turntable 4, a first driving member 7 and a material storage assembly; the turntable 4 is horizontally rotatably arranged on the bracket 3, the first driving member 7 is connected to the turntable 4, and the material storage assembly is arranged on the turntable 4. There are multiple material storage assemblies, and the multiple material storage assemblies are evenly spaced around the rotation axis of the turntable 4.

[0025] Each material storage assembly includes a limit frame 5, a tray 6, a second driving member 12 and a material detection element. The limit frame 5 is fixed on the turntable 4, the tray 6 is movably arranged on the limit frame 5, the second driving member 12 is connected to the tray 6, and the material detection element is arranged on the limit frame 5 and connected to the second driving member 12.

[0026] Specifically, the turntable 4 of the device is provided with a plurality of material storage components, so when working, the first driving member 7 can drive the turntable 4 to rotate periodically, so that one of the material storage components rotates to the feeding manipulator 1 for normal material supply, and the remaining material storage components are in a waiting state. At this time, if it is an empty material storage component, it waits to add materials, and if it is a full material storage component, it waits to rotate to the feeding manipulator 1 for feeding.

[0027] It should be noted that the turntable 4 in the present device does not rotate all the time, but only rotates when the position of the material storage assembly needs to be adjusted, and the angle of each rotation of the turntable 4 depends on the number of material storage assemblies set. Since multiple material storage assemblies are evenly arranged, for example, when there are two material storage assemblies, the turntable 4 can switch between different material storage assemblies by rotating 180 degrees each time, and when there are three material storage assemblies, the turntable 4 can switch between different material storage assemblies by rotating 120 degrees each time, and no further description will be given.

[0028] It can be seen from this that the various material storage components in the device work independently and do not affect each other. Therefore, the device can realize non-stop material feeding, and it is also convenient for operators to replenish materials to the remaining material storage components in their spare time without having to keep a close eye on the feeding situation, thereby improving the convenience of use.

[0029] In practical applications, such as Figure 2 As shown, the first driving member 7 includes a first motor 8 and a transmission mechanism. A pivot shaft is provided at the lower end of the turntable 4, and the pivot shaft is rotatably connected to the bracket 3. The first motor 8 is fixed on the turntable 4 and is connected to the pivot shaft through the transmission mechanism. The transmission mechanism is a belt transmission mechanism, thereby enabling the first motor 8 to drive the turntable 4 to rotate.

[0030] For stock components, Figure 2 and Figure 3As shown, the limiting frame 5 of the material storage assembly includes a base plate 9 and a baffle 10. The base plate 9 is fixedly connected to the turntable 4. A vertical baffle 10 is provided on the outer peripheral edge of the base plate 9. There are multiple baffles 10 and they are arranged at intervals along the circumferential edge of the base plate 9 to enclose a receiving groove for receiving materials. The multiple circumferentially distributed baffles 10 are used to limit the materials so that the materials can be kept neat and prevented from falling.

[0031] The tray 6 is provided with an avoidance groove 11 and can be slidably passed through one of the blocking rods 10 up and down through the avoidance groove 11. A part of the tray 6 is located in the receiving groove, and the other part is located outside the receiving groove and connected to the second driving member 12. The second driving member 12 includes a second motor 13, a screw rod and a slider 14. The turntable 4 is provided with a rod frame 15. The vertical screw rod is rotatably arranged on the rod frame 15. The second motor 13 is connected to the screw rod, the slider 14 is connected to the screw rod, and the tray 6 is fixedly connected to the slider 14. Therefore, when the second motor 13 is working, the tray 6 can be driven to move up and down through the screw rod slider 14 structure, so that the height of the material can be adjusted, which is convenient for the feeding robot 1 to grab the material.

[0032] In addition, a material detection element is also provided on the limit frame 5, and the second driving member 12 can automatically adjust the height position of the tray 6 according to the condition of the detected material. The material detection element includes an infrared transmitter and an infrared receiver, the infrared transmitter is provided on one of the baffles 10, and the infrared receiver is provided on the other baffle 10 located on the opposite side of the bottom plate 9, and the infrared transmitter is at the same height as the infrared receiver.

[0033] Therefore, after putting in a stack of materials, the position of the tray 6 is adjusted so that the top layer of materials just blocks the infrared rays. In this way, once the top layer of materials is taken out, the infrared receiver can receive the infrared rays again. At this time, the second driving member 12 will drive the tray 6 to rise a certain distance so that the new top layer of materials will block the infrared rays again. This will help the feeding robot 1 to always grab the top layer of materials normally.

[0034] In summary, the device utilizes the rotating turntable 4 to realize the switching feeding of multiple material storage components. Each material storage component works independently and does not affect each other. Therefore, the device can realize non-stop feeding of materials, and it is also convenient for operators to replenish materials to the idle material storage components in their spare time without having to keep a close eye on the feeding situation, thereby improving the convenience of use.

[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
