[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] In order to solve the technical problem that the punch press body needs to stop working when replacing the transfer frame, thereby reducing the processing efficiency, the utility model provides a punch press material collecting and stacking device, which can improve the processing efficiency of the punch press.

[0023] It should be noted that the punch press material collecting and stacking device described in the present invention is used for but not limited to punch presses, etc. For the convenience of explanation, in the present invention, only a punch press material collecting and stacking device applied to a punch press is used as an example for explanation. The principle of applying a punch press material collecting and stacking device to other types of equipment is essentially the same as that applied to a punch press, and will not be described one by one here.

[0024] See also Figure 1 - Figure 3 ,in Figure 1 This is a structural schematic diagram of a punch press material collecting and stacking device in one embodiment of the present invention, a punch press material collecting and stacking device includes a bracket 1 and a material storage assembly 2, the top of the bracket 1 is fixedly connected to a workbench 11, the workbench 11 is provided with a material passage 111, a plurality of material storage assemblies 2 are provided, and each material storage assembly 2 is evenly spaced along the circumference of the material passage 111, the material storage assembly 2 includes a guide block 21 and a telescopic block 22, the guide block 21 is provided with a through hole 211, the telescopic block 22 is slidably sleeved in the through hole 211 and can freely enter and exit the through hole 211.

[0025] In this embodiment, a stacking structure is formed by the setting of the material passage 111 and the guide block 21. By setting the telescopic block 22, when the material is full and the stack is changed, the telescopic block 22 extends out of the through hole 211, which can realize continuous blanking of the punching machine without stopping, effectively improving the processing efficiency of the punching machine.

[0026] Furthermore, a single-axis cylinder is connected to the end of the telescopic block 22 away from the material passage 111, and the opening and closing of the single-axis cylinder is controlled by the PLC computer end, thereby realizing automatic extension and retraction of the telescopic block 22 without manual operation.

[0027] In one embodiment, see Figure 1 - Figure 3 A chamfer 221 is formed on one end of the telescopic block 22 facing the material passage 111 .

[0028] In this embodiment, a spring is installed in the through hole 211, and the spring makes the end of the telescopic block 22 facing the material passage 111 always extend out of the through hole 211, so that the device can be used not only in the scenario of stamping and stacking, but also in the scenario of loading. When the device is used in the loading process, the sheets between the guide blocks 21 are continuously moved from bottom to top, and the external robot takes out the sheets one by one at the top of the guide block 21. When the sheets between the guide blocks 21 are insufficient, the sheets need to be replenished in time. The sheets will move from bottom to top under the action of the external lifting mechanism. During the movement, the sheets will contact the telescopic block 22, and under the action of the chamfer 221, the telescopic block 22 will shrink into the through hole 211 until all the sheets are higher than the telescopic block 22. The telescopic block 22 automatically extends out of the through hole 211 under the action of the spring and supports the newly replenished sheets. This process does not require the external robot to stop working, which effectively improves the loading efficiency.

[0029] In one embodiment, see Figure 1 - Figure 3 A protrusion 222 is provided at one end of the telescopic block 22 away from the material passage opening 111 .

[0030] In this embodiment, the function of the protrusion 222 is, on the one hand, to prevent the end of the telescopic block 22 away from the material passage 111 from extending into the through hole 211; on the other hand, it facilitates manual grasping, and the staff pulls the telescopic block 22 by grasping the protrusion 222.

[0031] Furthermore, the protrusion 222 is provided with a snap-on elastic rod. When punching and stacking, the telescopic block 22 needs to always be retracted in the through hole 211 to facilitate the material to fall directly onto the transfer frame along the guide block 21. When the transfer frame is full and needs to be replaced with an empty transfer frame, the telescopic block 22 will extend out of the through hole 211. Therefore, after the staff manually pulls the telescopic block 22, under the action of the snap-on elastic rod, the telescopic block 22 will not be affected by the elastic force of the spring and extend out of the through hole 211.

[0032] In one embodiment, see Figure 1 The top of the guide block 21 is fixedly connected with a magnetic spreader 23.

[0033] In this embodiment, when the device is used in the loading process, the provision of the magnetic spreader 23 (the magnetic spreader 23 is a conventional device in this field) facilitates an external robot arm to grab the sheets one by one from the top of the guide block 21 .

[0034] In one embodiment, see Figure 2 , and also includes a slide assembly 3, which is connected to the guide blocks 21 and is used to drive the guide blocks 21 to gather or disperse.

[0035] In one embodiment, see Figure 1 - Figure 3 The slide assembly 3 includes a slide rail 31, a screw 32 and a slider 33. The slide rail 31 is fixedly connected to the top of the workbench 11. Both ends of the screw 32 are rotatably connected to the slide rail 31. The slider 33 is provided with a threaded hole 331. The screw 32 is threadedly connected to the threaded hole 331, and the slider 33 is fixedly connected to the guide block 21.

[0036] In this embodiment, the arrangement of the slide assembly 3 enables the device to be applicable to sheets of different specifications.

[0037] In one embodiment, see Figure 1 - Figure 3 One end of the screw 32 away from the material passage 111 is fixedly connected to a hand wheel 321 .

[0038] In this embodiment, the staff manually rotates the hand wheel 321 to drive the screw 32 to rotate, thereby driving the slider 33 to move, so that the various guide blocks 21 can gather together or disperse with each other.

[0039] In one embodiment, see Figure 1 - Figure 3 The bottom end of the guide block 21 is provided with an inclined surface 212 .

[0040] In this embodiment, an inclined surface 212 is provided on the opposite side of each guide block 21. When the device is used in the loading process, it is convenient for the material sheet to enter between the guide blocks 21 from below, or when the device is used in the punching machine palletizing process, it is convenient for the material sheet between the guide blocks 21 to fall from below to the external transfer frame.

[0041] In one embodiment, see Figure 1 A photoelectric detection switch 12 is provided on the top of the workbench 11 , and the photoelectric detection switch 12 is located on one side of the material passage 111 .

[0042] In this embodiment, the photoelectric detection switch 12 is used to monitor the number of the blanks.

[0043] In one embodiment, see Figure 1 The top of the workbench 11 is fixedly connected with an adjustment frame 13 , and the photoelectric detection switch 12 is installed on the adjustment frame 13 .

[0044] In this embodiment, the arrangement of the adjustment frame 13 enables the photoelectric detection switch 12 to be installed at different heights, thereby being suitable for detecting sheets of different specifications.

[0045] In order to better understand the present invention, the following Figures 1 to 3 The technical solution of the utility model is described in detail:

[0046] This device can be used in two scenarios:

[0047] First, the punching and palletizing process eliminates the need for the punch press to stop. First, the telescopic block 22 is retracted into the through hole 211, and the external transfer frame is located below the guide block 21, so that the punched blanks can fall onto the transfer frame along the guide block 21. Then, when the transfer frame is full and needs to be replaced, the telescopic block 22 extends out of the through hole 211 to temporarily receive the blanks instead of the transfer frame until the empty transfer frame reaches the bottom of the guide block 21. Finally, the telescopic block 22 is retracted into the through hole 211 again, and the blanks fall onto the empty transfer frame. The above steps are repeated. The entire process does not require the punch press to stop waiting for the transfer frame to be replaced, effectively improving the processing efficiency of the punch press.

[0048] The second is loading, so that the loading process does not require shutdown. First, the telescopic block 22 extends out of the through hole 211 to receive the material. Under the action of the magnetic spreader 23, the external robot grabs the material one by one; then, when the material is almost used up and needs to be loaded and replaced, the external lifting mechanism drives the new stack of material to move upward. During the upward movement, the stack of material will contact the telescopic block 22. Under the action of the chamfer 221, the telescopic block 22 shrinks to the through hole 211 until the stack of material is higher than the telescopic block 22. The telescopic block 22 automatically extends out of the through hole 211 under the action of the spring and supports the newly replenished stack of material. This process does not require the external robot to stop loading, which effectively improves the loading efficiency.

[0049] The above specific implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
