[0002] Leather used in the tanning industry, after coating and drying, needs to be hung on the hanging rods of the drying line. Generally, this leather transfer step involves workers picking up the leather and hanging it on the hanging rods of the drying line. To pick up and hang the leather, workers must turn, lift it, hang it horizontally, and then turn back to wait for the next piece. This sequence of actions is repeated an average of 6-7 times per minute, making it very labor-intensive. Furthermore, the surface temperature of the heated leather leaving the drying equipment outlet is high, reaching 40-50°C. Workers are constantly exposed to this high temperature during the entire process. Summary of the Invention

[0005] In one embodiment, the conveying surface of the first conveyor belt and the conveying surface of the second conveyor belt are located on the same horizontal plane.

[0006] In one embodiment, the first horizontal conveying device further includes a first driving mechanism for driving the first conveyor belt to rotate, and the second horizontal conveying device further includes a second driving mechanism for driving the second conveyor belt to rotate, and the control circuit communicates with the first driving mechanism and the second driving mechanism.

[0007] In one embodiment, the first horizontal conveying device further includes a frame, and the frame is formed with a space for the peeling rod to move from one side of the first horizontal conveying device to a space between the first horizontal conveying device and the second horizontal conveying device.

[0008] In one embodiment, the first horizontal conveying device further includes a third detector for detecting the position of the leather conveyed by the first conveyor belt and the second conveyor belt.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0029] A leather conveying device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0030] See also Figures 1 to 3 According to an embodiment of the present invention, a leather conveying device is capable of conveying leather to a hanging position. For example, after the coated and dried leather leaves the discharge port of the drying equipment, the leather conveying device receives the leather and conveys the leather to the hanging rod of the hanging line.

[0031] The leather conveying device includes a first horizontal conveying device 1 and a second horizontal conveying device 2. The first horizontal conveying device 1 and the second horizontal conveying device 2 are arranged side by side. For example, the first horizontal conveying device 1 and the second horizontal conveying device 2 have substantially the same external dimensions and shape. The first horizontal conveying device 1 and the second horizontal conveying device 2 are arranged side by side in the direction in which the leather leaves the drying device. A preset gap is left between the first horizontal conveying device 1 and the second horizontal conveying device 2 to provide space for the leather lifting rod 3 of the leather conveying device to move.

[0032] Specifically, see Figure 4 and Figure 5 The first horizontal conveying device 1 includes a first conveyor belt 4 and a first detector 5 for detecting leather dropped onto the receiving end of the first conveyor belt 4. The first conveyor belt 4 may be composed of a plurality of PU welded belts arranged side by side. During the rotation of the first conveyor belt 4, the leather can be driven forward. Of course, the first conveyor belt 4 may also adopt other suitable structures, which are not listed here.

[0033] The first detector 5 may be a laser detector, positioned at or near the receiving end of the first conveyor belt 4. When light emitted by the laser detector strikes the leather falling onto the receiving end of the first conveyor belt 4, detection information is generated. It should be understood that the first detector 5 may also employ other devices capable of detecting the position of the leather, which are not specifically listed here.

[0034] See also Figure 6 and Figure 7 The second horizontal conveyor 2 includes a second conveyor belt 6 and a second detector 7 for detecting leather that has landed on the receiving end of the second conveyor belt 6. The second conveyor belt 6 can also be composed of several PU welded belts arranged side by side. During its rotation, the second conveyor belt 6 can drive the leather forward. Of course, the second conveyor belt 6 can also adopt other suitable structures, which are not listed here. The leather is located behind the first conveyor belt 4 and the second conveyor belt 6 at the same time, and is driven forward by the first conveyor belt 4 and the second conveyor belt 6.

[0035] The second detector 7 may also be a laser detector, positioned at or near the receiving end of the second conveyor belt 6. When light emitted by the laser detector strikes the leather falling onto the receiving end of the second conveyor belt 6, detection information is generated. It should be understood that the second detector 7 may also employ other devices capable of detecting the position of the leather, which are not specifically listed here.

[0036] Return now Figures 1 to 3 The leather conveying device further includes a lifting device, which includes a leather lifting rod 3. The leather lifting rod 3 can be moved between the first horizontal conveying device 1 and the second horizontal conveying device 2, and then lift the leather to a preset position. If the hanging rod for hanging the line can be moved to the preset position or below the preset position, the leather can be hung on the hanging rod by the leather lifting rod 3.

[0037] The leather conveying device also includes a control circuit (not shown in the figure), which adjusts the rotation speed of the first conveyor belt 4 and / or the second conveyor belt 6 according to the information detected by the first detector 5 and the second detector 7 when the leather falls on the corresponding conveyor belt, so that before the leather is lifted by the leather picking rod 3, the absolute value of the difference between the area of ​​the part of the leather located on the first conveyor belt 4 and the area of ​​the part located on the second conveyor belt 6 is less than a preset value, so that the center of gravity of the leather is located in the preset gap between the first horizontal conveying device 1 and the second horizontal conveying device 2, reducing or even avoiding the occurrence of leather slipping during the process of the leather picking rod 3 lifting the leather to the preset position.

[0038] Specifically, the first detector 5 and the second detector 7 are in communication with the control circuit, such as by electrical connection or wireless connection. When the first detector 5 detects leather falling onto the receiving end of the first conveyor belt 4, it transmits detection information to the control circuit. When the second detector 7 detects leather falling onto the receiving end of the second conveyor belt 6, it also transmits detection information to the control circuit. The control circuit adjusts the rotation speed of the first conveyor belt 4 and / or the second conveyor belt 6 based on the detection information transmitted by the first detector 5 and the second detector 7.

[0039] For example, when the first detector 5 detects that the leather has fallen onto the receiving end of the first conveyor belt 4, but the second detector 7 does not detect that the leather has fallen onto the receiving end of the second conveyor belt 6, the rotation speed of the first conveyor belt 4 is reduced. After the second detector 7 detects that the leather has fallen onto the receiving end of the second conveyor belt 6 and the leather has been transported a certain distance by both the first and second conveyor belts 4 and 6, the rotation speed of the first conveyor belt 4 is increased to the same speed as that of the second conveyor belt 6. At this time, the absolute value of the difference between the area of ​​the portion of the leather located on the first conveyor belt 4 and the area of ​​the portion of the leather located on the second conveyor belt 6 is less than a preset value, and the center of gravity of the leather is located within the preset gap between the first horizontal conveyor device 1 and the second horizontal conveyor device 2. The area of ​​the portion of the leather located on the first conveyor belt 4 and the area of ​​the portion of the leather located on the second conveyor belt 6 can be determined by detecting the weight of the portion of the leather located on the first conveyor belt 4 and the weight of the portion of the leather located on the second conveyor belt 6, or by detecting the contour of the portion of the leather located on the first conveyor belt 4 and the contour of the portion of the leather located on the second conveyor belt 6, or by other suitable methods, which are not listed here.

[0040] For another example, when the second detector 7 detects that the leather has fallen at the receiving end of the second conveyor belt 6, and the first detector 5 has not detected that the leather has fallen at the receiving end of the first conveyor belt 4, the rotation speed of the second conveyor belt 6 is reduced. After the first detector 5 detects that the leather has fallen at the receiving end of the first conveyor belt 4, and the leather has been transported a certain distance by the first conveyor belt 4 and the second conveyor belt 6, the rotation speed of the second conveyor belt 6 is increased to the same as the rotation speed of the first conveyor belt 4. At this time, the absolute value of the difference between the area of ​​the part of the leather located on the first conveyor belt 4 and the area of ​​the part located on the second conveyor belt 6 is less than the preset value, and the center of gravity of the leather is located within the preset gap between the first horizontal conveying device 1 and the second horizontal conveying device 2.

[0041] For another example, when the second detector 7 detects that the leather falls at the receiving end of the second conveyor belt 6, and the first detector 5 does not detect that the leather falls at the receiving end of the first conveyor belt 4, the rotation speeds of the first conveyor belt 4 and the second conveyor belt 6 remain unchanged. After the first detector 5 detects that the leather falls at the receiving end of the first conveyor belt 4, the rotation speed of the first conveyor belt 4 is increased. After the leather is transported a distance by the first conveyor belt 4 and the second conveyor belt 6, the rotation speed of the first conveyor belt 4 is reduced to the same as the rotation speed of the second conveyor belt 6. At this time, the absolute value of the difference between the area of ​​the part of the leather located on the first conveyor belt 4 and the area of ​​the part located on the second conveyor belt 6 is less than the preset value, and the center of gravity of the leather is located within the preset gap between the first horizontal conveying device 1 and the second horizontal conveying device 2.

[0042] For another example, when the second detector 7 detects that the leather has fallen at the receiving end of the second conveyor belt 6, and the first detector 5 has not detected that the leather has fallen at the receiving end of the first conveyor belt 4, the rotation speed of the second conveyor belt 6 is reduced and the rotation speed of the first conveyor belt 4 is increased. After the first detector 5 detects that the leather has fallen at the receiving end of the first conveyor belt 4 and the leather has been transported a certain distance by the first conveyor belt 4 and the second conveyor belt 6, the rotation speed of the first conveyor belt 4 and the rotation speed of the second conveyor belt 6 are both adjusted to the initial rotation speed. At this time, the absolute value of the difference between the area of ​​the part of the leather located on the first conveyor belt 4 and the area of ​​the part located on the second conveyor belt 6 is less than the preset value, and the center of gravity of the leather is located within the preset gap between the first horizontal conveying device 1 and the second horizontal conveying device 2.

[0043] Preferably, the conveying surface of the first conveyor belt 4 and the conveying surface of the second conveyor belt 6 are located on the same horizontal plane.

[0044] In this embodiment, the first horizontal conveying device 1 may further include a first driving mechanism for driving the first conveyor belt 4 to rotate. Figure 4 and Figure 5 As shown, the first driving mechanism may include a reduction motor 8, a driving wheel 9, a synchronous belt 10, a driven wheel 11, a tensioning wheel 12, a driving shaft 13, and a driven shaft 14. The first conveyor belt 4 is wound around the driving shaft 13 and the driven shaft 14. When the reduction motor 8 is working, its power is transmitted to the first conveyor belt 4 via the driving wheel 9, the synchronous belt 10, the driven wheel 11, and the driving shaft 13 in sequence. When the first conveyor belt 4 is composed of several PU welding belts, in order to maintain the gap between adjacent PU welding belts, the driving shaft 13 and the driven shaft 14 are also provided with a corresponding number of retaining rings 15. The reduction motor 8 is communicatively connected to the control circuit, such as electrically connected, and the control circuit adjusts the rotation speed of the first conveyor belt 4 by adjusting the output speed of the reduction motor 8. It should be understood that the first driving mechanism can also adopt other suitable structures, which are not listed here one by one.

[0045] The first horizontal conveyor 1 may further include a frame that provides installation space or a platform for other components of the first horizontal conveyor 1. The frame defines a space for the leather lifting rod 3 to move from one side of the first horizontal conveyor 1 to the space between the first horizontal conveyor 1 and the second horizontal conveyor 2. Specifically, the frame includes two arched side panels 16, with the arch openings facing horizontally toward one side of the first horizontal conveyor 1. The leather lifting rod 3 can pass through the arch bottoms of the side panels 16 and move to the space between the first horizontal conveyor 1 and the second horizontal conveyor 2.

[0046] The second horizontal conveying device 2 may further include a second driving mechanism for driving the second conveyor belt 6 to rotate. Figure 6 and Figure 7As shown, the second drive mechanism may include a worm gear reduction motor 17, a drive shaft 18, a driven shaft core 19, and a driven roller 20. The second conveyor belt 6 is wound around the drive shaft 18 and the driven roller 20. The worm gear reduction motor 17 is composed of a worm gear reducer and a motor. When the motor is working, its power is transmitted to the second conveyor belt 6 via the worm gear reducer and the drive shaft 18 in sequence. When the second conveyor belt 6 is composed of a number of PU welding belts, in order to maintain the gap between adjacent PU welding belts, the drive shaft 18 and the driven roller 20 are also provided with a corresponding number of retaining rings 21. The motor is communicatively connected to the control circuit, such as electrically connected, and the control circuit adjusts the rotation speed of the first conveyor belt 4 by adjusting the output speed of the motor. It should be understood that the second drive mechanism can also adopt other suitable structures, which are not listed here.

[0047] In one embodiment, the first conveyor belt 4 and the second conveyor belt 6 can also be powered by the same power source, such as a motor, and the power is transmitted to the first conveyor belt 4 and the second conveyor belt 6 through their respective transmission mechanisms. The control circuit can adjust the rotation speed of the first conveyor belt 4 and the second conveyor belt 6 by adjusting the transmission ratio of the corresponding transmission mechanism.

[0048] The second horizontal conveyor 2 may also include a frame to provide installation space or a platform for other components of the second horizontal conveyor 2. Since the movement trajectory of the lifting rod 3 does not pass through the first horizontal conveyor 1, the frame does not need to form a corresponding space for the lifting rod 3 to move through. The frames of the first and second horizontal conveyor 1 and 2 can be equipped with devices such as an adjustable base plate 22 and an adjustable foot cup 23 to enable fine-tuning of the height according to the actual site conditions.

[0049] Return now Figures 1 to 3 In this embodiment, the lifting device may further include a third drive mechanism 24, which drives the lifting rod 3 to perform set actions, such as horizontally moving the lifting rod 3 from one side of the first horizontal conveying device 1 to the space between the first horizontal conveying device 1 and the second horizontal conveying device 2, upwardly moving from the space between the first horizontal conveying device 1 and the second horizontal conveying device 2 to a preset position, and downwardly moving from the preset position. The third drive mechanism 24 may be composed of a motor, a corresponding transmission mechanism, a travel mechanism, etc. The motor is communicatively connected to the control circuit, such as electrically connected, and the motor operates according to instructions of the control circuit.

[0050] In one embodiment, the first conveyor belt 4, the second conveyor belt 6, and the leather picking rod 3 can also be powered by the same power source, such as a motor, and the power is transmitted to the first conveyor belt 4, the second conveyor belt 6, and the leather picking rod 3 through their respective transmission mechanisms. The control circuit adjusts the rotation speed of the first conveyor belt 4 and the second conveyor belt 6 by adjusting the transmission ratio of the corresponding transmission mechanism, and prompts the leather picking rod 3 to perform the set action by controlling the corresponding transmission mechanism and the walking mechanism.

[0051] In one embodiment, the first horizontal conveyor 1 may further include a third detector (not shown) for detecting the position of leather conveyed by the first and second conveyor belts 4 and 6. When the third detector detects that the leather has moved to a predetermined position, the leather lifting rod 3 lifts the leather to the predetermined position. The third detector may be a laser detector or other device capable of detecting the position of the leather. The third detector is in communication with the control circuit.

[0052] In another embodiment, the second horizontal conveyor 2 may further include a fourth detector (not shown) for detecting the position of leather conveyed by the first conveyor belt 4 and the second conveyor belt 6. When the fourth detector detects that the leather has moved to a predetermined position, the leather lifting rod 3 lifts the leather to the predetermined position. The fourth detector may be a laser detector or other device capable of detecting the position of the leather. The fourth detector is in communication with the control circuit.

[0053] In this embodiment, the leather conveying device may further include a horizontal movement device, including a leather hanging rod 25. The leather hanging rod 25 is capable of transferring the leather lifted to a preset position by the leather picking rod 3 to a hanging position. The addition of this horizontal movement device enables the leather conveying device to be adapted for use with other differently arranged hanging lines. For example, after the leather picking rod 3 lifts the leather to a preset position, the leather hanging rod 25 moves horizontally to the position of the leather picking rod 3, or to a position directly below the position of the leather picking rod 3. The leather picking rod 3 then moves downward, and the leather hanging rod 25 receives the leather. The leather hanging rod 25 then continues to move horizontally to hang the leather on the hanging rod of the hanging line, and then returns to its original position after the leather is lowered.

[0054] Specifically, the leather lifting rod 3 may include two first rods 26 arranged horizontally and in parallel, and the leather hanging rod 25 may include two second rods 27 arranged in parallel, with the distance between the two first rods 26 being greater than the distance between the two second rods 27. After the leather lifting rod 3 lifts the leather to a predetermined position, the two second rods 27 extend between the two first rods 26, or the two second rods 27 move to directly below the two first rods 26, and then the leather lifting rod 3 moves downward, and the leather hanging rod 25 receives the leather.

[0055] The horizontal movement device further includes a fourth drive mechanism 28, which drives the hanging bar 25 to perform a predetermined action, such as horizontal movement or hemming. The fourth drive mechanism 28 may be composed of a motor, a corresponding transmission mechanism, a travel mechanism, etc. The motor is communicatively connected to the control circuit, such as electrically connected, and operates according to the instructions of the control circuit.

[0056] In one embodiment, the first conveyor belt 4, the second conveyor belt 6, the leather picking rod 3, and the leather hanging rod 25 can also be powered by the same power source, such as a motor, and the power is transmitted to the first conveyor belt 4, the second conveyor belt 6, the leather picking rod 3, and the leather hanging rod 25 through their respective transmission mechanisms. The control circuit adjusts the rotation speed of the first conveyor belt 4 and the second conveyor belt 6 by adjusting the transmission ratio of the corresponding transmission mechanism, and prompts the leather picking rod 3 and the leather hanging rod 25 to perform the set action by controlling the corresponding transmission mechanism and the corresponding walking mechanism.

[0057] The leather conveying device of this embodiment can automatically transfer the leather from the discharge port of the drying equipment and hang it on the hanging rod of the hanging line. Since the first horizontal conveying device and the second horizontal conveying device adjust the leather during the leather transfer process, the center of gravity of the leather is located within the preset gap between the first horizontal conveying device and the second horizontal conveying device, which reduces or even avoids the leather slipping when the leather picking rod lifts the leather to the preset position; and when the hanging rod receives the leather, the contact part between the hanging rod and the leather is the same as or close to the contact part between the leather picking rod and the leather, which can reduce or even avoid the leather slipping on the hanging rod, and has high reliability.
