Description

Technical Field

[0001] This invention relates to the field of fabric handling, and more particularly to an unmanned fabric handling device. Background Technology

[0002] When transporting fabric rolls by truck, the rolls are piled up densely in the truck bed, leaving little room for operation. Unloading is done manually, and the repetitive unloading of large quantities of fabric rolls leads to worker fatigue and low unloading efficiency over time. There is currently a lack of devices to replace manual unloading of fabric.

[0003] After the fabric is rolled up, it is secured with ropes. To save costs and time, the ropes are usually only secured at both ends. The ropes cover a small area, while the fabric roll is relatively long. This means that the ropes at both ends are spaced far apart, and there is a free end hanging down on the part of the fabric roll that is far from the ropes. When loading the fabric roll, the free end hanging down is pressed down by the adjacent fabric roll, resulting in greater resistance when pulling the fabric roll axially during unloading. The fabric roll is difficult to move and pull out, and excessive force may even cause the ropes to come off and the fabric to be damaged. Summary of the Invention

[0004] To overcome the shortcomings of the lack of existing devices to replace manual unloading of fabric rolls, which result in fatigue and low unloading efficiency due to the long hours of manual unloading of large quantities of fabric rolls, and the fact that the free end of the fabric is pressed down by adjacent fabric rolls, leading to greater resistance when pulling the fabric rolls axially during unloading and making it difficult to move and pull out the fabric rolls, this invention provides a fabric unmanned transport device.

[0005] The technical solution is as follows: A fabric unmanned conveying device includes a mobile lifting assembly, a support block one, and a support block two; two mobile lifting assemblies are provided; support block one and support block two are respectively connected to the two mobile lifting assemblies; it also includes mounting block one, mounting block two, electric guide rails, moving blocks, a handling clamping assembly, and support plates; mounting block one is connected to support block one; mounting block two is connected to support block two; several electric guide rails are jointly installed between mounting block one and mounting block two; each electric guide rail is slidably connected to a moving block; a camera is installed on each moving block; all moving blocks are jointly connected to the handling clamping assembly; two support plates are connected between mounting block one and mounting block two via a rotating shaft.

[0006] Optionally, the mobile lifting assembly includes a trolley and electric cylinders; the trolley is equipped with several electric cylinders; the telescopic end of the electric cylinder of each mobile lifting assembly is fixedly connected to the corresponding support block one and support block two, respectively.

[0007] Optionally, the transport and clamping assembly includes an annular slide rail, an electric slider, a first electric push rod, and a clamping block; all moving blocks are connected to the annular slide rail; several electric sliders are rotatably connected to the annular slide rail; each electric slider is equipped with a first electric push rod; and each first electric push rod has a clamping block connected to its output end.

[0008] Optionally, a ball wheel is provided on the side of the movable block opposite to the annular slide rail.

[0009] Optionally, the transport clamping assembly also includes a linear drive; each first electric push rod output end is fixedly connected to a linear drive; the moving part of the linear drive is fixedly connected to the clamping block.

[0010] Optionally, it also includes roller one and roller two; several roller one are installed on the clamping block; several roller two are installed on each support plate; one roller rotates in one direction.

[0011] Optionally, the left end of the clamping block is arc-shaped.

[0012] Optionally, it also includes an electric rotating shaft and a limiting rotating shaft; the first mounting block is equipped with an electric rotating shaft; the first mounting block is rotatably connected to the first support block via the electric rotating shaft; the second mounting block is equipped with a limiting rotating shaft; the second mounting block is rotatably connected to the second support block via the limiting rotating shaft; the second support block has an arc-shaped groove; the limiting rotating shaft moves within the arc-shaped groove.

[0013] Optionally, it also includes a mounting frame, a suction cylinder, a second electric push rod, and a clamping plate; the mounting frame is connected to all moving blocks; the mounting frame has wheels on both sides; the moving blocks have grooves; the wheels move in adjacent grooves; the suction cylinder is fixed to the lower side of the mounting frame; the suction cylinder has a connection port on the right side; several second electric push rods arranged in a circular array are installed inside the suction cylinder; a clamping plate is fixed to the output end of each second electric push rod.

[0014] Optionally, the left inlet of the suction cylinder is truncated cone-shaped.

[0015] The beneficial effects of the present invention are: the present invention realizes the positioning and clamping of the fabric roll by inserting the clamping block into the gap around the fabric roll, and pulls the fabric roll out of the carriage for transportation. The present invention operates automatically, avoiding the problems of manual unloading operations, such as the fatigue of personnel and poor unloading efficiency caused by repeatedly unloading a large number of fabric rolls with the same operation over a long period of time.

[0016] The clamping block drives the clamped fabric roll to rotate, so that the drooping edge of the fabric roll is pulled out from the underside of the adjacent fabric roll with less radial frictional resistance. This avoids the drooping edge of the fabric roll being pressed down by the adjacent fabric roll, which would result in greater resistance when pulling the fabric roll axially during unloading, making it difficult to pull the fabric roll out.

[0017] The electric slider, the first electric push rod, and the linear drive control the clamping block to open to its limit position. The clamping block can cover a range greater than the distance between the two moving blocks and the outer diameter of the annular slide rail. It can clamp fabric rolls close to the side wall and bottom of the carriage, avoiding obstruction from the side wall and bottom of the carriage.

[0018] The components on mounting block one and mounting block two are deflected as a whole by electric rotating shaft and limit rotating shaft to adapt to the angle required for conveying the fabric roll.

[0019] The clamping plate pulls on the tied end of the fabric roll, assisting the clamping block in conveying the fabric. This prevents the clamping block from rubbing against the outer packaging, which would cause relative sliding between the outer packaging and the fabric roll, resulting in poor conveying or even damage to the outer packaging.

Detailed Implementation

[0032] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0033] Example 1

[0034] like Figures 1-7 As shown, an unmanned fabric conveying device includes a movable lifting assembly, a support block 2a, and a support block 2b; two movable lifting assemblies are provided; the support block 2a and the support block 2b are respectively connected to the two movable lifting assemblies; the movable lifting assembly drives the support block 2a and the support block 2b to move.

[0035] It also includes mounting block 3a, mounting block 3b, electric guide rail 21, moving block 22, handling clamping assembly, and support plate 5; mounting block 3a is connected to support block 2a; mounting block 3b is connected to support block 2b; two electric guide rails 21 are installed between mounting block 3a and mounting block 3b; a moving block 22 is slidably connected to the upper side of each electric guide rail 21; a camera 2201 is installed on the left side of the moving block 22; a handling clamping assembly is connected to the left side of all moving blocks 22; two support plates 5 are connected between mounting block 3a and mounting block 3b through a rotating shaft, and the two support plates 5 are both arc-shaped and merge to form a U-shaped groove; the support plates 5 can be rotated by a motor.

[0036] The mobile lifting assembly includes a trolley 1 and an electric cylinder 101; two electric cylinders 101 are installed on the trolley 1; the telescopic end of the electric cylinder 101 of each mobile lifting assembly is fixedly connected to the corresponding support block 2a and support block 2b respectively.

[0037] The transport and clamping assembly includes an annular slide rail 31, an electric slider 32, a first electric push rod 41, and a clamping block 4; all moving blocks 22 are connected to the annular slide rail 31 on their left side; four electric sliders 32 are rotatably connected to the annular slide rail 31; a first electric push rod 41 is installed on the left side of each electric slider 32; a clamping block 4 is connected to the output end of each first electric push rod 41; the circle formed by the positions of all clamping blocks 4 is concentric with the annular slide rail 31.

[0038] A ball wheel is provided on the side of the movable block 22 opposite to the annular slide rail 31 to reduce the friction when the movable block 22 contacts the inner wall of the carriage 1111.

[0039] The handling and clamping assembly also includes a linear drive 42; each first electric push rod 41 has a linear drive 42 fixedly connected to its output end; the linear drive 42 consists of an electric slide rail and a slider; the moving part of the linear drive 42 is fixedly connected to the clamping block 4.

[0040] It also includes roller 4001 and roller 5001; several rollers 4001 are installed on the clamping block 4; several rollers 5001 are installed on each support plate 5. Roller 4001 can only rotate counterclockwise when viewed from front to back and cannot rotate clockwise. When the clamping block 4 is inserted into the gap of the fabric roll 2222, the friction of the clamping block 4 entering the gap of the fabric roll 2222 is reduced by the rotational contact between roller 4001 and the surface of the fabric roll 2222, thus reducing the moving resistance of the clamping block 4. When the clamping block 4 clamps the fabric roll 2222 and pulls it to the right, the roller 4001 cannot rotate, thus preventing slippage between the clamping block 4 and the fabric roll 2222.

[0041] The left end of the clamping block 4 is arc-shaped, which makes it easy for the clamping block 4 to enter the gap of the fabric roll 2222.

[0042] This invention moves to such a position via a movable lifting component. Figure 2On the right side of the carriage 1111 shown, the carriage 1111 is in the open state. A transport vehicle 3333 is parked under the support plate 5. The fabric rolls 2222 are transported layer by layer from top to bottom. First, the camera 2201 determines the location, and the electric cylinder 101 is pushed out, causing the parts on it to rise to the required height of the fabric rolls 2222, so that the center of the electric slider 32 is aligned with the center of the individual fabric roll 2222. Then, the moving block 22 is controlled to move to the left along the electric guide rail 21. 2. The conveying and clamping assembly is moved. It should be noted that since the fabric roll 2222 is cylindrical or nearly cylindrical, even if multiple fabric rolls 2222 are stacked, there are rectangular gaps around each individual fabric roll 2222. The clamping blocks 4 are moved by the electric slider 32, the first electric push rod 41, and the linear drive 42, so that each clamping block 4 aligns with the gaps around the fabric roll 2222. Thus, when the conveying and clamping assembly moves to the left, each clamping block 4 is inserted around the fabric roll 2222. In the gap, the left end of the clamping block 4 is arc-shaped to facilitate its entry into the gap of the fabric roll 2222. Then, all the first electric push rods 41 are extended to drive the corresponding clamping blocks 4 to move, so that the clamping blocks 4 move closer to each other and the diameter of the circle formed by the clamping blocks 4 gradually decreases until the clamping blocks 4 contact the surface of the fabric roll 2222, clamping the right side of the fabric roll 2222. Then, the moving block 22 is controlled to move to the right along the electric guide rail 21, driving the clamping blocks 4 to move to the right, and thus the clamping blocks 4 clamp the fabric roll 2222. The fabric roll 2222 is pulled out from the carriage 1111 and conveyed onto the support plate 5. When the left side of the fabric roll 2222 is completely inside the U-shaped groove formed by the two support plates 5, the clamping blocks 4 are opened to release the clamping on the right side of the fabric roll 2222. The moving block 22 continues to drive the clamping block 4 to move to the right along the electric guide rail 21. Through the friction between the fabric roll 2222 and the support plate 5, the right side of the fabric roll 2222 is disengaged from the clamping block 4, so that the fabric roll 2222 is completely inside the support plate 5.During the above process, when the drooping edge of the fabric roll 2222 being transported is pressed down by the adjacent fabric roll 2222, the resistance to axially pulling the fabric roll 2222 during unloading is relatively large, making it difficult to pull out the fabric roll 2222. After the clamping block 4 clamps the right side of the fabric roll 2222, all the electric sliders 32 are simultaneously controlled to rotate on the annular slide rail 31. In turn, the electric sliders 32 drive the first electric push rod 41 and the clamping block 4 to rotate. The clamping block 4 drives the clamped fabric roll 2222 to rotate, so that the drooping edge of the fabric roll 2222 experiences less friction in the radial direction. The resistance is pulled out from the underside of the adjacent fabric roll 2222, thereby preventing the drooping edge of the fabric roll 2222 being pressed down by the adjacent fabric roll 2222, which would result in greater resistance when pulling the fabric roll 2222 axially during unloading, making it difficult to pull out the fabric roll 2222. Then, the clamping block 4 pulls the clamped fabric roll 2222 out of the carriage 1111 and conveys it to the support plate 5. During this process, the electric slider 32 continues to rotate, so that the drooping edge of the fabric roll 2222 remains wrapped around the fabric roll 2222, preventing further obstruction during the conveying process.

[0043] Once the fabric roll 2222 is completely within the support plate 5 and the fabric roll 2222 is detached from the clamping block 4, then... Figure 5 As shown, the two support plates 5 are opened by controlling the fabric rolls 2222 to fall naturally into the transport vehicle 3333 for storage. Then, by moving the trolley 1 back and forth and the electric cylinder 101 up and down, other fabric rolls 2222 are transported to the transport vehicle 3333 and transferred to other places through the transport vehicle 3333, thus completing the unloading work of the transport vehicle 3333.

[0044] It should be understood that the length of the electric guide rail 21 and the moving block 22 is longer than the length of a single fabric roll 2222. When the right side of the fabric roll 2222 is closer to the inside of the carriage 1111, the moving block 22 can continue to move to the left on the electric guide rail 21, so that the handling clamping assembly can go deeper into the carriage 1111 and thus handle the fabric roll 2222.

[0045] It should be noted that the clamping block 4 is opened to its limit position by the electric slider 32, the first electric push rod 41, and the linear drive component 42. Figure 7 As shown, the clamping block 4 can cover a range greater than the distance between the two moving blocks 22 and the outer diameter of the annular slide rail 31. Therefore, when the clamping assembly is transported into the carriage 1111, the moving blocks 22 and the annular slide rail 31 do not affect the clamping block 4's clamping and transporting of the fabric rolls 2222 near the sides and bottom of the carriage 1111.

[0046] In summary, by inserting the clamping block 4 into the gaps around the fabric roll 2222 for positioning and clamping, the fabric roll 2222 is pulled out and transported from the carriage 1111. This invention operates continuously and automatically, avoiding the problems of repeated unloading of a large number of fabric rolls 2222 by manual unloading operations, which can lead to personnel fatigue and poor unloading efficiency over a long period of time.

[0047] Example 2

[0048] Based on Example 1, such as Figure 1 and Figures 8-10 As shown, it also includes an electric rotating shaft 51 and a limiting rotating shaft 52; the electric rotating shaft 51 is installed on the lower side of the mounting block 3a, and the electric rotating shaft 51 can be driven to rotate by an electric motor; the mounting block 3a is rotatably connected to the support block 2a through the electric rotating shaft 51; the limiting rotating shaft 52 is installed on the lower side of the mounting block 3b; the mounting block 3b is rotatably connected to the support block 2b through the limiting rotating shaft 52; an arc-shaped groove 2001 is provided on the support block 2b; the limiting rotating shaft 52 moves within the arc-shaped groove 2001; when the moving lifting assembly is fixed, the electric rotating shaft 51 causes the mounting block 3a to rotate relative to the support block 2a, and the mounting block 3b rotates and deflects on the support block 2b with the electric rotating shaft 51 as the center of rotation, and the limiting rotating shaft 52 moves within the arc-shaped groove 2001, thereby causing the parts on the mounting block 3a and the mounting block 3b to deflect as a whole to adapt to the angle required for conveying the fabric roll 2222.

[0049] When the fabric roll 2222 has a large self-weight, in the embodiment, when the conveying clamping assembly enters the carriage 1111 to move and transport the fabric roll 2222 near the side wall of the carriage 1111, the right side of the fabric roll 2222 is in a deflected state. When it is conveyed through the conveying clamping assembly, one side will have greater friction with the parts of the conveying clamping assembly, resulting in greater conveying resistance. The moving lifting assembly needs to be fixed to ensure that its relative position with the transport vehicle 3333 cannot cause the entire invention to move or be adjusted. Therefore, when the moving lifting assembly is fixed, the electric rotating shaft 51 causes the mounting block 3a to rotate relative to the support block 2a, and the mounting block 3b rotates and shifts on the support block 2b with the electric rotating shaft 51 as the rotation center point. The limiting rotating shaft 52 moves within the arc groove 2001, thereby causing the parts on the mounting block 3a and mounting block 3b to deflect as a whole. Figure 8 As shown, to adapt to the angle required for conveying the fabric roll 2222, after the fabric roll 2222 is completely conveyed onto the support plate 5, the electric rotating shaft 51 is controlled to rotate so that the mounting block 3a and the mounting block 3b are reset. Then the support plate 5 opens so that the fabric roll 2222 falls into the transport vehicle 3333.

[0050] Example 3

[0051] Based on Example 2, such as Figure 1 , Figure 3 , Figure 7 and Figure 11 As shown, it also includes a mounting frame 61, a suction cylinder 62, second electric push rods 63, and clamping plates 64; all moving blocks 22 are connected to the mounting frame 61; the mounting frame 61 is provided with wheels on both sides, which are driven by electric motors to rotate, thereby moving the mounting frame 61; a sliding groove 2202 is provided on the upper side of the moving block 22; the wheels move in adjacent sliding grooves 2202; a suction cylinder 62 is welded to the lower side of the mounting frame 61; a connection port 6201 is provided on the right side of the suction cylinder 62; four second electric push rods 63 are installed in the suction cylinder 62 in a circular array; a clamping plate 64 is fixed to the output end of each second electric push rod 63; each second electric push rod 63 pushes out the clamping plate 64, so that all clamping plates 64 form a clamping function, clamping the outer packaging tie on the right side of the fabric roll 2222, and then pulling the fabric roll 2222 to move when the suction cylinder 62 moves, so as to avoid the outer packaging affecting the handling of the fabric roll 2222.

[0052] The left inlet of the suction cylinder 62 is truncated cone-shaped, which increases the coverage area when the suction cylinder 62 is suctioning, guides the outer packaging of the fabric roll 2222 to close, and makes it easier for the clamping plate 64 to clamp.

[0053] Typically, the fabric roll 2222 is also wrapped in a plastic outer packaging for protection. When the fabric roll 2222 with outer packaging is clamped and pulled by the clamping block 4, the clamping block 4 rubs against the outer packaging, causing relative sliding between the outer packaging and the fabric roll 2222, resulting in uneven pulling and even damage to the outer packaging. Therefore, before starting the handling operation, connect the suction device to the connection port 6201. Before pulling out the fabric roll 2222 with the clamping block 4 clamping its right side, control the mounting frame 61 to move to the desired position. Figure 7 As shown, the left side of the suction cylinder 62 will then be attached to the right side of the fabric roll 2222, covering the tie-up opening of the outer packaging of the fabric roll 2222. At this time, the suction device is activated, and the tie-up opening of the outer packaging of the fabric roll 2222 will be sucked into the suction cylinder 62. The tie-up opening is located between each clamping plate 64. Then, each second electric push rod 63 is controlled to push out the corresponding clamping plate 64 to clamp the tie-up opening. Next, the clamping block 4 is controlled to pull the fabric roll 2222 outward. At the same time, the mounting frame 61 moves to the right along the moving block 22. Then, the clamping plate 64 pulls on the clamped tie-up opening of the fabric roll 2222, causing the fabric roll 2222 to gradually move to the right into the support plate 5, assisting the clamping block 4 in conveying the fabric roll 2222. This prevents the clamping block 4 from rubbing against the outer packaging, which would cause relative sliding between the outer packaging and the fabric roll 2222, resulting in poor conveying or even damage to the outer packaging.
