They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0047] Please refer to Figures 1-6 This embodiment provides a material return device for conveying a material box 100. The material box 100 is used to load materials. After the material box 100 containing materials is loaded into the material return device, the operator takes out the materials from the material box 100. The material boxes 100 are automatically conveyed out one by one from the material return device so that the operator can collect them.
[0048] Please refer to Figures 1-6 The material handling and return device includes a frame 10, a material handling rack 20, and a feeding conveyor line 30, a return conveyor line 40, and a reversing mechanism 50 located on the frame 10. The material handling rack 20 is equipped with a material handling platform 21, on which operators can take materials from the material box 100 onto the material handling platform 21. The feeding conveyor line 30 is inclined relative to the horizontal plane, with its lower end facing the material handling platform 21. The return conveyor line 40 is also inclined relative to the horizontal plane, with its upper end facing the material handling platform 21. The inclination directions of the feeding conveyor line 30 and the return conveyor line 40 are opposite, and the return conveyor line 40 is located below the feeding conveyor line 30. The reversing mechanism 50 can swing around a horizontal axis to switch between a first posture and a second posture: when in the first posture, the reversing mechanism 50 is connected to the lower port of the feeding conveyor 30, and the reversing mechanism 50 can receive the material box 100 sent out by the feeding conveyor 30; when in the second posture, the reversing mechanism 50 is connected to the upper port of the return conveyor 40, and the material box 100 on the reversing mechanism 50 can be transported to the return conveyor 40.
[0049] Specifically, the material picker 20 is installed on one side of the frame 10, while the feeding conveyor 30, the return conveyor 40, and the reversing mechanism 50 are installed in the frame body of the frame 10. The feeding end of the material picker 100 and the recycling end of the material recycling bin 100 are both located on the side of the frame 10 away from the material picker 20. When the reversing mechanism 50 is in the first posture, the height of the bearing surface of the reversing mechanism 50 for receiving the material bin 100 is lower than that of the material picker platform 21, so that the height of the material picker opening (located at the upper end) of the material bin 100 is close to the height of the material picker platform 21, which facilitates the material picker operation of the operator. During operation, the operator or the feeding equipment can put the material box 100 into the upper port of the feeding conveyor line 30. The material box 100 slides along the feeding conveyor line 30 toward the picking platform 21. When the material box 100 slides out from the lower port of the feeding conveyor line 30, the reversing mechanism 50 is in the first position. The reversing mechanism 50 receives the material box 100. The material box 100 is located next to the picking platform 21. The operator can take the material from the material box 100 to the picking platform 21. After the material is taken out, the reversing mechanism 50 swings to the second position, and the material box 100 on it slides down to the return conveyor line 40. Finally, the material box 100 slides out along the return conveyor line 40. In summary, the material handling and recycling device provided in this embodiment, by setting a swingable reversing mechanism 50, can selectively connect with the feeding conveyor line 30 and the recycling conveyor line 40, change the conveying direction of the material box 100, so that it can flow sequentially along the feeding conveyor line 30, the reversing mechanism 50 and the recycling conveyor line 40, and recycle the material box 100 one by one, solve the problem of feeding and recycling the material box 100, improve the degree of automation, reduce working hours, reduce production costs and improve production efficiency.
[0050] For example, please refer to Figures 1-3 The material handling platform 21 is provided with an avoidance gap 22, which is used to avoid the material box 100 that the reversing mechanism 50 receives when it is in the first position. When the reversing mechanism 50 is in the first position, the reversing mechanism 50 is connected to the feeding conveyor line 30, and the material box 100 protrudes from the avoidance gap 22 to the top of the material handling platform 21, making it convenient for operators to pick up the material.
[0051] For further details, please refer to [link / reference]. Figures 1-3 The material handling platform 21 also includes a lighting element 23, which is installed above the material handling platform 21 and faces the material handling platform 21 to provide lighting for the operators performing the material handling operation. Preferably, the lighting element 23 can be LED beads, lamp tubes, etc.
[0052] For example, please continue to refer to Figures 1-3The feeding conveyor line 30 includes parallel feeding rollers 31 and feeding guide plates 32, both of which are inclined relative to the horizontal plane. At least two feeding rollers 31 are arranged side-by-side, each including multiple rollers distributed along its extension direction. Feeding guide plates 32 are provided on both sides of the feeding conveyor line 30. A feeding guide block 33 is provided at one end of the feeding guide plate 32 near the upper port of the feeding conveyor line 30, and the feeding guide block 33 has a guide arc surface that gradually expands outwards. Specifically, after the material box 100 is placed into the upper port of the feeding conveyor line 30, it slides downwards along the feeding rollers 31. During this process, the feeding guide plates 32 on both sides limit the sliding trajectory of the material box 100. The feeding guide blocks 33 facilitate the placement of the material box 100, preventing jamming.
[0053] For example, please refer to Figures 1-4 The frame 10 is provided with a first crossbar 11 and a second crossbar 12. Both the first crossbar 11 and the second crossbar 12 are set in the horizontal direction. The height of the first crossbar 11 is higher than the height of the second crossbar 12. The first crossbar 11 fixes and supports a part of the feeding roller 31 near the upper end of the feeding conveyor line 30, while the second crossbar 12 fixes and supports a part of the feeding roller 31 near the lower end of the feeding conveyor line 30. The horizontal inclination angle of the feeding conveyor line 30 is determined by the difference in support height between the first crossbar 11 and the second crossbar 12.
[0054] For example, please refer to Figures 1-4The material return device also includes a material blocking assembly 60, which includes a material blocking drive 61 and a movable stop bar 62. The main body of the material blocking drive 61 is mounted on the frame 10, and the movable stop bar 62 is mounted on the output end of the material blocking drive 61. Under the drive of the material blocking drive 61, the movable stop bar 62 can selectively extend from the lower port of the feeding conveyor line 30 to block or release the material box 100 on the feeding conveyor line 30. Specifically, the material blocking drive 61 adopts a telescopic drive component such as a linear cylinder or an electric push rod. Its body is rotatably connected to the first crossbar 11 through the first hinge seat 15. The middle part of the movable stop rod 62 is rotatably mounted on the second crossbar 12 through the second hinge seat 16. One end of the movable stop rod 62 is hinged to the output end of the material blocking drive 61, and the other end is provided with a material blocking hook plate 63. The material blocking hook plate 63 is set as an L-shaped plate structure. When the material blocking drive 61 telescopically moves, it drives the movable stop rod 62 to rotate around the horizontal axis, so that the material blocking hook plate 63 selectively extends from the lower port of the feeding conveyor line 30. In this embodiment, when the material blocking drive 61 retracts, the end of the movable stop 62 with the material blocking hook 63 rotates upward, and the material blocking hook 63 rises from the bottom of the lower port of the feeding conveyor 30, which can restrict the material box 100 from sliding out of the lower port of the feeding conveyor 30. After the reversing mechanism 50 moves to the lower port of the feeding conveyor 30, the material blocking drive 61 extends, and the material blocking hook 63 retracts from the lower port of the feeding conveyor 30 to allow the material box 100 to slide onto the reversing mechanism 50.
[0055] For example, please refer to Figures 1-3 The return conveyor line 40 includes return roller tracks 41 and return guide plates 42 arranged parallel to each other. Both return roller tracks 41 and return guide plates 42 are inclined relative to the horizontal plane. At least two return roller tracks 41 are arranged side by side. Each return roller track 41 includes multiple rollers distributed along its extension direction. Return guide plates 42 are provided on both sides of the return conveyor line 40. A return guide block 43 is provided at one end of the return guide plate 42 near the upper port of the return conveyor line 40. The return guide block 43 is provided with a guide arc surface that gradually expands outward. Specifically, after the material box 100 enters the upper port of the return conveyor line 40 from the reversing mechanism 50, it slides downward along the return roller track 41. During this process, the return guide plates 42 on both sides limit the sliding trajectory of the material box 100. The return guide block 43 facilitates the placement of the material box 100 and avoids jamming.
[0056] For example, please refer to Figures 1-4The frame 10 is equipped with a third crossbar 13 and a fourth crossbar 14, both horizontally oriented. The height of the third crossbar 13 is greater than that of the fourth crossbar 14. The third crossbar 13 fixes and supports a portion of the return conveyor 41 near the upper end of the return conveyor line 40, while the fourth crossbar 14 fixes and supports a portion of the return conveyor 41 near the lower end of the return conveyor line 40. The horizontal inclination angle of the return conveyor line 40 is determined by the height difference between the third crossbar 13 and the fourth crossbar 14. Specifically, the third crossbar 13 is located directly below the second crossbar 12 and directly below the first crossbar 11.
[0057] For example, please refer to Figure 3 , Figure 5 and Figure 6 The reversing mechanism 50 includes a reversing drive 51 and a reversing conveyor line 52. The reversing conveyor line 52 is rotatably connected to the frame 10 around a horizontal axis on the side near the material picker 20. The body of the reversing drive 51 is connected to the frame 10, and the movable end of the reversing drive 51 is connected to the reversing conveyor line 52. The reversing drive 51 can drive the reversing conveyor line 52 to swing up and down around a horizontal axis so that the reversing conveyor line 52 docks with the loading conveyor line 30 or the return conveyor line 40. Specifically, when the reversing drive 51 drives the reversing conveyor line 52 to swing upward to a first posture, the reversing conveyor line 52 docks with the lower end of the loading conveyor line 30; when the reversing drive 51 drives the reversing conveyor line 52 to swing downward to a second posture, the reversing conveyor line 52 docks with the upper end of the return conveyor line 40.
[0058] Specifically, please refer to Figure 5 and Figure 6 The reversing drive component 51 employs linear telescopic components such as linear cylinders and electric actuators. Its main body is hinged to the frame 10 via a third hinge seat 18. Its extendable drive end is hinged to the reversing conveyor line 52. Through the extension and retraction of the reversing drive component 51, the reversing conveyor line 52 can be driven to pitch and swing, thereby allowing the reversing conveyor line 52 to switch between a first posture and a second posture. Preferably, the extension and retraction stroke of the reversing drive component 51 is adjustable, allowing the elevation angle of the reversing conveyor line 52 in the first posture to be adjustable, thus improving versatility.
[0059] In some embodiments, the reversing drive 51 may also be a power structure composed of a rotary drive and a cam. By changing the angle of the cam, the height of the cam top supporting the reversing transmission line 52 is adjusted, thereby driving the reversing transmission line 52 to pitch and swing.
[0060] For example, please refer to Figure 5 and Figure 6The reversing mechanism 50 also includes a support 54, which is fixed to the frame 10. The reversing conveyor line 52 includes a swing seat 521, which is rotatably connected to the support 54 via a swing shaft 55. The swing seat 521 has two reversing raceways 522 arranged side by side and two reversing guide plates 523 arranged at intervals. The reversing raceways 522 and the reversing guide plates 523 are arranged parallel to each other. The reversing raceways 522 have multiple rollers distributed along their extension direction for supporting and conveying the material box 100. The reversing guide plates 523 are used to limit the sliding trajectory of the material box 100 on the reversing raceways 522. Furthermore, both ends of the reversing guide plates 523 are provided with outwardly expanding guide portions 5231. The guide portions 5231 at both ends are designed to facilitate the sliding of the material box 100 from the loading conveyor line 30 to the reversing conveyor line 52, and from the reversing conveyor line 52 to the return conveyor line 40, avoiding the occurrence of box jamming and improving reliability.
[0061] For example, please refer to Figure 5 and Figure 6 Two baffle blocks 53 are provided at the end of the swing seat 521 away from the feeding conveyor line 30. The two baffle blocks 53 are arranged side by side with intervals. The baffle blocks 53 protrude upward from the bearing surface of the feeding conveyor line 30 to prevent the material box 100 from sliding downward and detaching from the feeding conveyor line 30.
[0062] For example, please refer to Figures 4-6 A push rod 17 is also installed at the bottom of the frame 10. The push rod 17 includes a connecting part 171 and a pushing part 172. The connecting part 171 is arranged along the height direction, with its lower end connected to the frame 10 and its upper end connected to the pushing part 172. The pushing part 172 extends horizontally and is located below the side of the swing seat 521 opposite to the feeding conveyor line 30 and the return conveyor line 40. When the reversing mechanism 50 is in the first posture, the push rod 17 supports the bottom of the swing seat 521 to improve stability.
[0063] For example, when the reversing mechanism 50 is in the first posture, the highest point of the receiving surface of the reversing roller 522 receiving the hopper 100 is not higher than the lowest point of the receiving surface of the hopper 100 on the loading roller 31, ensuring that the hopper 100 on the loading conveyor line 30 can slide onto the reversing conveyor line 52. Furthermore, the height difference between the highest point of the receiving surface of the reversing roller 522 and the lowest point of the receiving surface of the loading roller 31 does not exceed one-fifth of the height of the hopper 100, and the horizontal distance between the reversing roller 522 and the loading roller 31 is less than half the width of the hopper 100 in the conveying direction, ensuring that the hopper 100 can slide smoothly onto the reversing mechanism 50. Similarly, when the reversing mechanism 50 is in the second posture, the lowest point of the receiving surface of the reversing roller 522 is not lower than the highest point of the return roller 41, ensuring that the hopper 100 on the reversing conveyor line 52 can slide onto the return conveyor line 40. Furthermore, the height difference between the lowest point of the receiving surface of the reversing roller 522 and the highest point of the receiving surface of the return roller 41 does not exceed one-fifth of the height of the hopper 100, and the horizontal distance between the reversing roller 522 and the return roller 41 is less than half the width of the hopper 100 in the conveying direction, ensuring that the hopper 100 can slide smoothly onto the return conveyor line 40.
[0064] As for the tilt angle of the reversing mechanism 50, it can be set to be the same as the tilt angle of the feeding conveyor line 30 or the return conveyor line 40 based on the requirement of smoothness, or it can be set to be slightly larger or slightly smaller than the tilt angle of the feeding conveyor line 30 or the return conveyor line 40 based on the requirement of conveying speed adjustment. The angle difference is preferably within 10°.
[0065] In this embodiment, please refer to Figures 1-3 When the reversing mechanism 50 is in the first position, the reversing conveyor line 52 is connected to the feeding conveyor line 30, and the receiving surface of the reversing conveyor line 52 is coplanar with the receiving surface of the feeding conveyor line 30. The material box 100 can smoothly slide from the feeding conveyor line 30 onto the reversing mechanism 50, reducing vibration of the material box 100 during transfer and improving reliability. When the reversing mechanism 50 is in the second position, when the reversing conveyor line 52 is connected to the return conveyor line 40, the receiving surface of the reversing conveyor line 52 is coplanar with the receiving surface of the return conveyor line 40. The material box 100 can smoothly slide from the reversing mechanism 50 onto the return conveyor line 40, reducing vibration of the material box 100 during transfer and improving reliability.
