DETAILED DESCRIPTION

[0029] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0030] Please participate Figure 1 and Figure 2 The embodiment of the present application provides a re-investment machine 100, comprising a re-investment line device 1, a lifting line device 2, a feeding line device 3 and a lifting device 4. Figure 2The re-investment line device 1 is used to transport materials along the first direction (AA direction). The lifting line device 2 is arranged on one side of the re-investment line device 1 along the first direction (AA direction). The lifting line device 2 is used to transport materials along the second direction (BB direction), and the second direction (BB direction) intersects with the first direction (AA direction). The feeding line device 3 is arranged on one side of the re-investment line device 1 along the first direction (AA direction). The feeding line device 3 is used to receive materials transported from the re-investment line device 1 and transport the materials along the first direction (AA direction) to the lifting line device 2; the lifting device 4 is driven and connected to the lifting line device 2, and the lifting device 4 is used to make the lifting line device 2 move up and down. The above-mentioned re-investment machine 100 can be set on the entire logistics line, and the entire logistics line can transport materials along the second direction (BB direction). The re-investment line device 1 is located outside the entire logistics line and can operate independently without occupying the entire line space, and will not affect the normal operation of materials on the entire line. The feeding line device 3 is located on the entire line and can receive items transported from the re-feeding line device 1, and transport the items along the first direction (AA direction) to the lifting line device 2. The lifting line device 2 transports the materials transported from the feeding line device 3 along the second direction (BB direction) to the logistics line. Driven by the lifting device 4, the lifting line device 2 can perform lifting movements to realize the transportation of materials in different height directions of the entire line. The re-feeding line device 1 can prepare the items to be re-fed in advance outside the entire line. The feeding line device 3 can quickly transfer the materials on the re-feeding line device 1 to the lifting line device 2. The lifting line device 2 merges the materials onto the entire line, thereby making the entire re-feeding process smooth and efficient, avoiding material pauses. The re-feeding machine 100 of the present application avoids the problem of the line being occupied by transferring the re-feeding operation to the outside of the entire line. The entire line can continue to operate according to a predetermined rhythm without being disturbed by the operation of the re-feeding machine 100. Although the feeding line device 3 is located on the entire production line, it moves with the entire production line and can quickly complete the reception and transfer of items without significantly affecting the production rhythm of the entire production line. The coordination of the lifting line device 2 and the lifting device 4 can also efficiently complete the lifting and conveying of items, ensuring the rapid re-feeding operation without affecting the production rhythm of the entire production line.

[0031] See also Figure 3In an optional embodiment, the re-cast line device 1 may be a belt conveyor or a roller conveyor. In some embodiments, the re-cast line device 1 includes a re-cast line support 11, a fourth drive assembly, and a plurality of second rollers 12. All second rollers 12 are rotatably connected to the re-cast line support 11 and are sequentially spaced along the first direction (direction AA). The fourth drive assembly is drivably connected to all second rollers 12. Conveying via the second rollers 12 is relatively simple, and each second roller 12 is relatively independent. If a second roller 12 malfunctions, such as inflexible rotation or damage, it can be repaired or replaced individually.

[0032] In an alternative embodiment, the second roller 12 can be a powered roller or an unpowered roller. When the second roller 12 is a powered roller, the fourth drive assembly is internal to the second roller 12. When the second roller 12 is an unpowered roller, the fourth drive assembly is located external to the second roller 12. Both powered and unpowered rollers are commercially available and are transmission components well known to those skilled in the art, and will not be described in detail here.

[0033] See also Figure 3 In an optional embodiment, the re-casting line device 1 further includes a first anti-slip member 13, which is sleeved on the second roller 12. The provision of the first anti-slip member 13 can limit the axial movement of the material along the second roller 12, thereby reducing the movement of the material on the re-casting line device 1. The first anti-slip member 13 may include multiple first anti-slip members 13, which are spaced apart on the second roller 12. The first anti-slip member 13 can be made of rubber or plastic.

[0034] See also Figure 3 In an optional embodiment, the re-cast line device 1 further includes a first position sensor 14. The first position sensor 14 is disposed on the re-cast line support 11 and is capable of detecting the presence of material on the re-cast line device 1 and the position of the material. Optionally, the first position sensor 14 may be a photoelectric position sensor or an ultrasonic position sensor.

[0035] In an optional embodiment, the feeding line device 3 can be a roller conveyor device or a belt conveyor device. When the feeding line device 3 is a roller conveyor device, the lifting line device 2 is a belt conveyor device. When the feeding line device 3 is a belt conveyor device, the lifting line device 2 is a roller conveyor device.

[0036] See also Figure 4 and Figure 5In some embodiments, the feed line device 3 includes multiple conveyor assemblies spaced apart from one another and a first drive assembly. Each conveyor assembly includes a conveyor belt support 31, a conveyor belt 32, and a tensioning pulley 33. The conveyor belt 32 is wound around the tensioning pulley 33, which is fixed to the conveyor belt support 31. The first drive assembly is drivably connected to the tensioning pulley 33, driving the tensioning pulley 33 to move the conveyor belt 32 in a first direction (direction AA). Multiple, spaced apart conveyor assemblies can better accommodate materials of varying sizes and shapes. When materials are conveyed along the feed line device 3, the different conveyor assemblies can support and convey the items from multiple locations. For example, for rectangular materials, multiple conveyor assemblies can evenly apply support along the length of the material, preventing deformation or tilting due to single-point support, thereby ensuring material stability during conveyance. The conveyor belt 32 is wound around the tensioning pulley 33, ensuring that the conveyor belt 32 maintains appropriate tension. During the conveying process, appropriate tension can ensure good contact between the conveyor belt 32 and the material, preventing the conveyor belt 32 from loosening and causing the material to slip or conveying to be unsmooth. In addition, the tensioning wheel 33 is fixed to the conveyor belt bracket 31, providing stable support for the conveyor belt 32, further enhancing the stability of the conveying.

[0037] See also Figure 5 In an alternative embodiment, the first drive assembly may include multiple rotary actuators, each of which is configured to rotate a tensioning pulley 33 on a conveyor assembly. To reduce the number of rotary actuators, in some embodiments, the first drive assembly includes a rotary actuator and a transmission roller 34. The output end of the rotary actuator is drive-connected to the transmission roller 34. The conveyor belt support 31 is provided with mounting holes 311 extending along the second direction, and the transmission rollers 34 are sequentially inserted through the mounting holes 311. At least two tensioning pulleys 33 in each conveyor assembly are positioned on either side of the transmission roller 34 along the first direction (direction AA). The conveyor belt 32 is simultaneously wound around the tensioning pulleys 33 and the transmission rollers 34. Thus, the power of the rotary actuator is evenly transmitted to the tensioning pulleys 33 on each conveyor assembly via the transmission rollers 34. All conveyor assemblies move synchronously with the rotation of the transmission rollers 34, ensuring consistent power transmission throughout the entire feed line assembly 3. By providing both a rotary actuator and a transmission roller, the number of rotary actuators required can be reduced, while also conserving installation space and compacting the feed line assembly 3.

[0038] In an optional embodiment, the rotary drive is a rotary motor or a rotary electric cylinder.

[0039] See also Figure 6In some embodiments, the lifting line device 2 includes a lifting line support 21, a second drive assembly and a plurality of first rollers 22. All the first rollers 22 are rotatably connected to the lifting line support 21 and are sequentially spaced along the second direction (BB direction) on the lifting line support 21. The second drive assembly is rotatably connected to all the first rollers 22. Figure 6 and Figure 2 The lifting line supports 21 are located on either side of each conveying assembly along the first direction (AA), and each conveying assembly is located in the gap between two adjacent first rollers 22 along the second direction (BB). It is understood that the conveying assemblies of the feed line device 3 and the first rollers 22 of the lifting line device 2 are arranged in an interlaced manner, and the setting position of the feed line device 3 coincides with the setting position of the lifting line device 2, which can ensure a tighter connection between the feed line device 3 and the lifting line device 2. Materials can be transferred from the feed line device 3 to the lifting line device 2 in situ, and the change in the material's movement direction can be more smoothly connected, reducing the risk of material jamming and falling during the transfer process.

[0040] See also Figure 2 In some embodiments, the placement surface of the first roller 22 is aligned with the placement surface of the conveyor belt 32 in the conveyor assembly. This allows materials to be smoothly transferred from the conveyor belt 32 of the feed line device 3 to the first roller 22 of the lifting line device 2. During the material transfer process, there are no collisions, jams, or dropped items due to height differences, ensuring a continuous and smooth material transfer, thereby improving the conveying efficiency of the entire re-investment machine 100.

[0041] See also Figure 6 In an optional embodiment, the lifting line device 2 further includes a second anti-slip member 23, which is sleeved over the first roller 22. The second anti-slip member 23 can limit the axial movement of the material along the first roller 22, thereby reducing the movement of the material on the lifting line device 2. The second anti-slip member 23 may include multiple second anti-slip members 23, which are spaced apart on the second roller 12. The second anti-slip member 23 can be made of rubber or plastic.

[0042] See also Figure 6 In an optional embodiment, the lifting line device 2 further includes a second position sensor 24. The second position sensor 24 is disposed on the lifting line support 21 and is capable of detecting the presence and position of material on the lifting line device 2. Optionally, the second position sensor 24 may be a photoelectric position sensor or an ultrasonic position sensor.

[0043] See also Figure 7In some embodiments, the lifting device 4 includes a support assembly 41 and a third drive assembly. The third drive assembly is connected to the support assembly 41, which is in turn connected to the lifting line device 2. The third drive assembly is used to drive the lifting line device 2 to move up and down. The support assembly 41 is used to support the third drive assembly. The third drive assembly can be driven by a motor screw 43 assembly, or by a motor synchronous belt and synchronous pulley assembly. The lifting device 4 drives the lifting line device 2 up and down, enabling docking at different heights of multiple layers of material lines, allowing for the entry and exit of materials on material lines at different heights.

[0044] See also Figure 7 In some embodiments, the third drive assembly includes a lifting driver 42, a screw rod 43, and a slide 44. The screw rod 43 is rotatably connected to the support assembly 41, the screw rod 43 is connected to the output shaft of the lifting driver 42, the slide 44 is transmission-connected to the screw rod 43, and the slide 44 is connected to the lifting line device 2. The output shaft of the lifting driver 42 drives the screw rod 43 to rotate, and the screw rod 43 is transmission-connected to the slide 44, so that the rotational motion of the screw rod 43 is converted into linear motion of the slide 44, so that the slide 44 can be lifted and lowered. The use of the screw rod 43 and the slide 44 to drive the lifting and lowering of the lifting line device 2 has high transmission efficiency, high rigidity and stability, can withstand large radial and axial loads, and maintain lifting stability.

[0045] See also Figure 8 In some embodiments, the reinvestment machine 100 further includes a protective device 5, which includes a frame assembly 51 and a baffle assembly 52. ​​The baffle assembly 52 is fixed to the frame assembly 51 to form a protective cover. The protective cover is provided around the outer periphery of the lifting line device 2, the feeding line device 3, and the lifting device 4. The protective device 5 can isolate the lifting line device 2, the feeding line device 3, and the lifting device 4, thereby improving the safety of the automation system.

[0046] See also Figure 8 In an optional embodiment, the re-investment machine 100 further includes a control device, which is disposed on the protective device 5 and includes a control button panel 61, a code reader 62, and a display panel 63. The control button panel 61 is used for manual intervention, which is convenient and quick. The code reader 62 and display panel 63 can display information about materials and material frames, and connect to the logistics system.

[0047] In a second aspect, an embodiment of the present application further provides a logistics system, in which a reinvestment machine 100 as in the first aspect is provided on the logistics line of the logistics system.

[0048] In summary, the embodiment of the present application provides a re-investment machine 100 that is set on the logistics line. There is no need to pause and wait for the materials before and after the re-investment, and the operation of the materials on the line is not affected, so the rhythm of the entire line is maintained. In addition, the re-investment machine 100 can automatically rise and fall according to the height of the multi-layer line body, and no manual handling is required, which saves time and effort, and does not require manual contact with the internal line body, which is safer. Manual intervention often affects the scheduling of the entire system and affects the intelligence of logistics. After the re-investment machine 100 is re-invested, no manual intervention is required. The system automatically replenishes the re-invested materials when the materials on the line are insufficient and automatically distributes them.
