[0002] The drawer-type material transfer device is a common feeding structure in industrial production. It provides materials through the multi-layer drawer structure of the silo set up above and below. When one group of silos is feeding at the loading position, the other group of silos can stay at the preparation position to prepare materials; multiple groups of silos are transferred to the loading position in turn, thereby ensuring the uninterrupted operation of the loading process.

[0003] In the prior art, silos usually use electrical components such as motors and cylinders to automatically drive displacement. There are errors in the travel of electrical components, and a large number of sensors are required to accurately locate the location of the materials. In addition, silos with electrical components do not perform well in scenarios such as long-distance material flow and silo replacement. There are also silos with manual braking and positioning silos in the prior art, but the manual efficiency is obviously low and cannot meet the automated production needs in industrial technology.

DETAILED DESCRIPTION

[0025] like Figure 1 The drawer-type material positioning and transferring device shown includes a bracket 1 and at least one group of silos 2 stacked on the bracket 1. The multiple groups of silos 2 are located at the preparation position when not in use, and the loading direction is set to the first direction. When in use, the silos 2 can be moved from the preparation position to the loading position along the first direction of the bracket 1, waiting for an external clamping device to clamp the material in the silo 2.

[0026] like Figure 2 and Figure 3 As shown, the silo 2 includes a material storage plate 3, and positioning blocks 4 are fixedly arranged on both sides of the material storage plate 3. At the same time, a rotating shaft 5 extending along a second direction perpendicular to the first direction is arranged at the bottom of the material storage plate 3, and the rotating shaft 5 is passed through and rotatably connected to the positioning block 4.

[0027] The positioning block 4 is provided with a latch structure for positioning the position of the silo 2. Figures 4 to 6 As shown, the bayonet structure includes a connecting cam 6 and a guide pin 7, wherein a vertical guide slot 8 is provided on the positioning block 4, and the guide pin 7 is slidably connected in the vertical guide slot 8, one end of the connecting cam 6 is fixedly connected to the end of the rotating shaft 5, and the other end of the connecting cam 6 is rotatably connected to the guide pin 7. Therefore, when the rotating shaft 5 rotates, the connecting cam 6 can be driven to rotate, thereby driving the guide pin 7 at the other end of the connecting cam 6 to extend in and out of the vertical guide slot 8.

[0028] The bracket 1 is provided with a pin hole 9 at a position corresponding to the guide pin 7, and the guide pin 7 can extend in and out of the pin hole 9 when moving in the vertical guide groove 8. When the guide pin 7 extends out of the pin hole 9, the silo 2 can freely move along the first direction of the bracket 1 to adjust its position on the bracket 1; when the guide pin 7 is inserted into the pin hole 9, the position of the silo 2 on the bracket 1 is locked, and the silo 2 no longer moves. At this time, the external clamping device can freely take out the product from the silo 2 without worrying about the problem of failed clamping due to inaccurate positioning during the material transfer process.

[0029] Specifically, a slot 10 is provided at the lower end of the guide pin 7 along the center axis direction, and one end of the connecting cam 6 extends into the slot 10; a radially extending connecting hole 11 is provided in the slot 10 of the guide pin 7, and an oblong hole 12 is provided at the position of the connecting cam 6 corresponding to the connecting hole 11, and a fastener 13 is inserted into the connecting hole 11 and the oblong hole 12, so that the connecting cam 6 can drive the guide pin 7 to move vertically when it rotates.

[0030] The installation process of the bayonet structure in this embodiment is as follows: install the guide pin 7 from the vertical guide groove 8 into the positioning block 4, extend one end of the connecting cam 6 into the slot 10 of the guide pin 7, and use the fastener 13 to pass through the connecting hole 11 and the oblong hole 12 in sequence to fix the relative positions of the guide pin 7 and the connecting cam 6.

[0031] Furthermore, a plurality of fixed blocks 14 are fixedly provided at the bottom of the material storage plate 3, and the rotating shaft 5 is rotatably arranged between the fixed blocks 14. The fixed blocks 14 and the positioning blocks 4 jointly limit the position of the material storage plate 3, and the material storage plate 3 does not rotate when the rotating shaft 5 rotates. A pull rod 15 is provided on the outside of one end of the material storage plate 3, and the pull rod 15 is fixedly connected to the rotating shaft 5 through a connecting frame 16. Applying a rotational force in a circumferential direction to the pull rod 15 can drive the rotating shaft 5 to rotate, thereby causing the guide pin 7 in the bayonet structure to disengage from the pin hole 9. At this time, the pull rod 15 is dragged in the second direction to adjust the position of the silo 2 on the bracket 1.

[0032] Furthermore, a spring 17 is provided between the connecting frame 16 and the end of the material storage plate 3. Under the action of external force, the rotating shaft 5 is released from the locked position, and the spring 17 provides elastic support for the material storage plate 3 during the sliding process of the material storage plate 3. When the external force is removed after reaching the target position, the spring 17 recovers its deformation, thereby driving the connecting frame 16, the pull rod 15 and the rotating shaft 5 to return to the initial position, and the guide pin 7 at the end of the rotating shaft 5 automatically extends into the pin hole 9, completing the fixing of the position of the silo 2.

[0033] The pin holes 9 of this embodiment are divided into two groups corresponding to the material preparation position and the material loading position, and are respectively arranged on the brackets 1 on both sides of the silo 2. The guide pins 7 are automatically inserted into the pin holes 9 during the sliding process of the silo 2.

[0034] Furthermore, side rollers 18 are fixedly provided on both sides of the material storage plate 3, and the bracket 1 is provided with U-shaped rails 19 on both sides of the material storage plate 3, and the side rollers 18 are slidably connected to the groove edges of the U-shaped rail 19 along the extension direction of the U-shaped rail 19, and the pin hole 9 is provided at one of the groove edges of the U-shaped rail 19.

[0035] The pull rod 15 of this embodiment can be opened manually in the same conventional manner as the drawer structure, or can be automatically controlled by an external clamping device. Specifically, the clamping device is set at the output end of the three-axis mobile module or the six-axis robot to automatically control the rotation of the pull rod 15, thereby realizing the full automation of the loading process.

[0036] Furthermore, a spring roller 20 is provided at the bottom of the bracket 1. The provision of the spring roller 20 can realize the movement of the entire device, and facilitate travel between various workstations over a long distance.

[0037] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
