[0038] Example:

[0039] refer to Figures 1 to 3A bar or tube feeding device includes: a frame 1, a hopper 2, a top feeding mechanism, and a feeding mechanism. The hopper 2 is disposed on the frame 1 and includes a storage chute 201, a guide plate 202, and a feeding guide chute 203. Along a first direction, the first end of the storage chute 201 is the feeding side, and the second end of the storage chute 201 is connected to the first end of the feeding guide chute 203 via the guide plate 202. The second end of the feeding guide chute 203 is the discharge side. The first end of the storage chute 201 is higher than the second end of the storage chute 203, so that the bar or tube 19 can automatically roll along the first end of the storage chute 201 to the second end. The first end of the feeding guide chute 203 is higher than the second end of the feeding guide chute 203, so that the bar or tube 19 can automatically roll along the first end of the feeding guide chute 203 to the second end. The second end; the end where the guide plate 202 is connected to the loading guide slide 203 is higher than the end where the guide plate 202 is connected to the storage slide 201, so that the connection between the loading guide slide 203 and the storage slide 201 forms a stepped portion, and the stepped portion has a plurality of top-feeding holes 204 arranged at intervals along the second direction; the top-feeding mechanism is set on the frame 1 and located below the stepped portion, and the top-feeding mechanism is used to pass through the top-feeding holes 204 and cooperate with the guide plate 202 to lift a single bar or tube, so as to transfer it from the storage slide 201 to the loading guide slide 203; the feeding mechanism and the processing device (in this embodiment, a CNC lathe) are arranged along the second direction, and the feeding mechanism is installed on the frame 1 and close to the discharge side of the loading guide slide 203; it is used to receive the bar or tube rolling off the loading guide slide 203 and feed it out along the second direction, the first direction being perpendicular to the second direction.

[0040] In this device, the first end of the storage chute 201 is the feeding side. Rods or pipes are added to the first end of the storage chute 201 via a mechanical gripper or manually. Because the first end of the storage chute 201 is higher than its second end, the rods or pipes automatically roll to the second end after entering the first end. A guide plate 202 is provided at the second end of the storage chute 201. The guide plate 202 first stops the rods or pipes from rolling. Then, the ejector mechanism extends along the ejector hole and lifts the single rod or pipe (the ejector mechanism's ejector...). The guide plate corresponds to the diameter of a single bar or tube to ensure that only one bar or tube can be lifted at a time. At this point, the guide plate and the lifting mechanism work together to convey the single bar or tube upwards. When the single bar or tube (hereinafter referred to as the workpiece) is higher than the second end of the guide plate, it is transferred to the feeding guide slide. Because the first end of the feeding guide slide is higher than its second end, and its first end is connected to the guide plate, while its second end is close to the feeding mechanism, the workpiece transferred to the feeding guide slide will automatically roll down to the feeding mechanism, and then be conveyed out along the second direction. This device can realize automatic feeding of bars or tubes, eliminating the need for long-term repetitive manual work, effectively improving production efficiency and avoiding production accidents.

[0041] refer to Figure 4 The material-ejecting mechanism includes a material-distributing ejector rod and an ejector cylinder 3; the material-distributing ejector rod includes a support 4 and multiple ejector blocks 5; the multiple ejector blocks 5 are spaced apart along a second direction on the support 4, and each ejector block 5 corresponds one-to-one with an ejector hole; the ejector cylinder 3 is mounted on the frame 1, and the output end of the ejector cylinder 3 is connected to the support 4 to drive the ejector blocks 5 through the ejector holes. (Reference) Figure 1 and Figure 4 Since both the storage slide 201 and the loading guide slide 203 are inclined, in order to better lift the workpiece, the lifting cylinder 3 is inclinedly installed on the frame 1 through the lifting cylinder mounting plate 301. Moreover, the contact surface between the lifting block 5 and the single bar or tube is an inclined plane 501. By setting the inclined plane 501, the contact area with the workpiece can be increased, making the lifting process more stable. At the same time, when the lifting block 5 lifts the single bar or tube to the loading guide slide, without the obstruction of the guide plate, the workpiece can roll along the inclined plane 501 to the loading guide slide.

[0042] refer to Figure 6It also includes a height adjustment mechanism; the height adjustment mechanism includes a lifting cylinder 6 and a first base plate 7. The lifting cylinder 6 is mounted on the frame 1, and its output end is connected to the first base plate 7. The first base plate 7 is horizontally positioned and extends along a second direction. The output end of the lifting cylinder 6 can reciprocate along a third direction (the third direction is vertical) to drive the first base plate 7 to move along the third direction. The feeding mechanisms are all mounted on the first base plate 7, and the first direction, the second direction, and the third direction are perpendicular to each other. The height adjustment mechanism can adjust the height of the feeding mechanism along the third direction, thereby adapting it to the loading guide slides 203 of different heights and aligning with the three-jaw chucks of CNC lathes of different heights. To improve the support capacity of the height adjustment mechanism, two or more lifting cylinders can be provided.

The output end of the lifting cylinder 7 is connected to the slide block 10 through the lifting connecting plate 11. The second base plate 8 is installed on the side of the lifting connecting plate 11 away from the slide block 10. The moving drive mechanism is installed on the second base plate 8 and its output end is connected to the first base plate 7 and can reciprocate along the second direction. The moving drive mechanism is a rodless cylinder 17 (commonly available rodless cylinders). The cylinder body of the rodless cylinder 17 extends along the second direction and is mounted on the second base plate 8. The slider of the rodless cylinder 17 is connected to the first base plate 7. The first base plate 7 is also provided with a slide rail 9, which is connected to the lifting connecting plate 11 via a slide block 10. Therefore, when the rodless cylinder 17 is activated, the first base plate and the feeding mechanism on the first base plate can move along the second direction (the slide rail 9 and the slide block 10 are slidably connected). In addition, the moving mechanism is connected to the lifting connecting plate 11 via the second base plate 8. When the lifting cylinder is activated, the second base plate 8, the moving drive mechanism, and the feeding mechanism rise and fall simultaneously. With the above configuration, the height adjustment of the feeding mechanism can be satisfied, and the range of movement of the feeding mechanism along the second direction can be extended to feed a single bar or tube to the position corresponding to the three-jaw chuck of the CNC lathe. It can also push the finished bar or tube to the unloading station to achieve automatic unloading.

[0044] Specifically, the lifting connecting plate 11 includes a first rod segment 1101 distributed along a third direction and a second rod segment 1102 distributed along a first direction.

The lifting connecting plate 11 is generally L-shaped. The upper end face of the second rod segment 1102 is connected to the slide block 10, and the lower end face of the second rod segment 1102 is connected to the second base plate 8. By setting the lifting connecting plate 11, the lifting cylinder 6 can adjust the height of the feeding mechanism along the third direction without affecting the movement of the feeding mechanism along the second direction.

[0045] refer to Figures 7-9 The feeding mechanism includes a receiving groove 12, a pushing drive assembly, and a pushing rod 13. The receiving groove 12 is disposed on the platform 1 and extends along a second direction. The pushing drive assembly is disposed on the platform 1 and located above the receiving groove 12. The output end of the pushing drive assembly is connected to the pushing rod 13 and is used to drive the pushing rod 13 to reciprocate along the second direction to feed a single rod or tube in the receiving groove 12 out along the second direction. Specifically, the receiving groove 12 is installed on the upper surface of the first substrate 7. The pushing drive mechanism is a rodless pushing cylinder 16 (commonly available rodless cylinders). The cylinder body of the rodless pushing cylinder 16 extends along the second direction and is mounted on the first substrate through a connecting frame. The slider of the rodless pushing cylinder 17 is connected to the pushing rod 13, thereby pushing the pushing rod 13 to slide along the cylinder body of the rodless pushing cylinder 17.

[0046] Specifically, refer to Figure 6 and Figure 9 The receiving trough 12 includes a receiving plate and a V-shaped trough. The receiving plate is disposed on both sides of the opening end of the trough. The receiving plate extends the opening of the trough outward in the horizontal direction. When the bar or tube rolls down along the feeding guide slide, it can smoothly enter the trough under the overlap of the receiving plate and prevent the bar or tube from falling out of the trough.

[0047] refer to Figure 6 This embodiment also includes a baffle plate 14, which is disposed on a receiving plate away from the feeding guide slide 203 to prevent the bar or tube from falling out of the trough.

[0048] refer to Figure 9 It also includes a discharge guide block 15; the discharge guide block 15 is disposed in the receiving groove 12, and the discharge guide block 15 has a guide hole that runs through the second direction to ensure that the bar or tube is fed out in the second direction.

[0049] refer to Figure 8The push rod 13 includes a limiting block 1301, a connecting rod, a push block 1302, and a spring 1303. The limiting block 1301, connecting rod, and push block 1302 are connected sequentially. The outer diameters of both the limiting block 1301 and the push block 1302 are larger than the connecting rod. A positioning block 18 extending towards the push rod 13 is provided on the slider of the push rodless cylinder 16. The positioning block 18 has a through hole that matches the outer diameter of the connecting rod. The connecting rod is disposed within the through hole. The push block 1302 is close to the processing device (CNC lathe), and the limiting block 1301 is away from the processing device. The spring 1303 is sleeved on the outer periphery of the connecting rod, with one end of the spring 1301 abutting against the push block 1302 and the other end of the spring 1303 abutting against the positioning block. This arrangement provides a good buffering effect during the pushing process, preventing damage to the bar or tube 19.

[0050] In practice:

[0051] The bar or tube 19 is fed from the external storage slide 201. The bar or tube 19 automatically rolls to the guide plate 202. At this time, the ejector cylinder 3 is activated, lifting the single bar or tube to the loading guide slide 203, and then automatically rolling down into the receiving groove 12. The rodless cylinder 17 for overall movement is activated, moving the first substrate 7 along the slide rail 9 as a whole. Then, the rodless cylinder 16 for pushing is activated, pushing the bar or tube into the processing device (the three-jaw chuck of the CNC lathe).
