Description

Technical Field

[0001] The invention relates to the technical field of grey cloth roll production, in particular to a grey cloth roll positioning, stacking and piling device. Background Art

[0002] Grey fabric rolls refer to the original fabric rolls that have not been dyed, printed or other post-processing steps. In the textile industry, they are the basic raw materials for many subsequent processing links and are widely used in the production of various clothing, home textile products, industrial fabrics, etc. Therefore, in the textile production process, the grey fabric rolls need to be positioned, stacked and piled according to certain rules to neatly stack the grey fabric rolls, thereby effectively utilizing the space in the warehouse or production workshop, improving production efficiency and facilitating subsequent handling, processing and management.

[0003] At present, there are the following disadvantages when stacking grey cloth rolls: when stacking grey cloth rolls, it is usually necessary to transport the grey cloth rolls to the clamping area of ​​the robot, and then use the robot to clamp a grey cloth roll and place it on the corresponding loading plate, and repeat this action until a row of grey cloth rolls is placed, and then the upper and lower rows of grey cloth rolls are stacked in a perpendicular state to each other, and then this process is repeated to complete the stacking and stacking of the grey cloth rolls. However, because the robot clamps the grey cloth rolls one by one and places them, the overall stacking efficiency is reduced, and after the placement of the grey cloth rolls, the distance between each grey cloth roll is uneven due to its own rolling and the error of the robot, which makes the overall structure of the stacking and stacking not compact enough, which not only wastes storage space and reduces space utilization efficiency, but also makes the entire stacking structure unstable, making it prone to collapse or slipping, thereby increasing safety hazards.

[0004] Therefore, in order to neatly stack the grey cloth rolls, effectively utilize the space in a warehouse or production workshop, improve production efficiency, and facilitate subsequent handling, processing, and management, the present invention provides a grey cloth roll positioning, stacking, and stacking device.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1.

[0020] 4. The positioning, stacking and stacking device for the grey cloth rolls, through the coordinated use of the transport mechanism and the clamping mechanism, locks the clamping mechanism and the transport mechanism during the process of the clamping mechanism loading the grey cloth rolls, so that the position stability of the clamping mechanism when loading the grey cloth rolls is ensured, so as to ensure that each grey cloth roll can be accurately loaded to the predetermined position, thereby ensuring the consistency and accuracy of the position during the stacking process, and the operator does not need to frequently manually correct the position of the clamping mechanism and the transport mechanism, thereby saving processing time.

[0038] It should be noted that there is an unclear expression "传动连接" in the original text, which may need to be further clarified to ensure more accurate translation. It is tentatively translated as "传动连接" here.During specific operation, when it is necessary to position and stack the grey fabric rolls, the hydraulic cylinder 415 and the first motor 413 are in an unstarted state at this time, so that the support arm 414 drives the load platform 611 to be located above the symmetrically arranged mating support blocks 521 front and back. Under the action of gravity, the U-shaped carriers 636 on both sides will be respectively placed on the upper end surfaces of the corresponding mating support blocks 521. At this time, start the second motors 524 on both sides to drive their respective first bidirectional screws 523 to rotate, so that the limit sliders on the left and right sides of the mating support blocks 521 drive the corresponding extrusion rods 522 to approach the mating block 637 until the two extrusion rods 522 respectively abut against the approaching sides of the V-shaped grooves. At this time, stop the operation of the second motors 524, thus fixing the U-shaped carriers 636 on the mating support blocks 521, thereby ensuring the stability of the position of the clamping mechanism 6 when loading the grey fabric rolls, so as to ensure that each grey fabric roll can be accurately loaded into the predetermined position.

[0039] Subsequently, the grey fabric rolls are placed on the conveyor belt 513 one by one by the external manipulator fixedly installed on the base 1. Then, start the external motor fixedly installed on the elliptical plate 511 to drive the belt roller 512 to rotate, so as to transport the placed grey fabric rolls to between the symmetrically arranged U-shaped carriers 636 front and back. At this time, the front and rear ends of the grey fabric roll are respectively located inside the symmetrically arranged U-shaped carriers 636 front and back. Wait until multiple grey fabric rolls reach inside the U-shaped carriers 636 on both sides, and then stop the operation of the external motor.

[0040] Please refer to Figure 1 and Figure 6 As shown in, the pushing part 62 includes a connecting arm 621, a sliding groove 622, a first sliding plate 623, a second sliding plate 624, a special-shaped support block 625 and a pushing plate 626. Symmetrically arranged connecting arms 621 are hinged on the connecting block 612. Symmetrically arranged sliding grooves 622 are formed through the lower pressing plate 614 front and back. A first sliding plate 623 is slidably installed in the sliding groove 622 at the rear side. One end of the connecting arm 621 on the left side away from the connecting block 612 is hinged to the left end of the first sliding plate 623. A second sliding plate 624 is slidably installed in the sliding groove 622 at the front side. One end of the connecting arm 621 on the right side away from the connecting block 612 is hinged to the right end of the second sliding plate 624. Special-shaped support blocks 625 are fixedly installed at the right end of the first sliding plate 623 and the left end of the second sliding plate 624. Pushing plates 626 are fixedly installed at the lower ends of the special-shaped support blocks 625 through support columns.

[0041] During specific operation, when the transport mechanism 5 transports the grey cloth roll to the clamping mechanism 6, the hydraulic pump fixedly installed on the support arm 414 is started so that the telescopic end of the hydraulic cylinder 415 lowers the loading platform 611. At this time, the force-bearing platform 632 is in a fixed state under the action of the matching part 52. During the descending process of the loading platform 611, it will first move downward with the lower pressure plate 614 under the action of the spring 615. During this process, the second sliding rods 631 on both sides limit the downward movement direction of the lower pressure plate 614.

[0042] When the lower pressure plate 614 contacts the force-bearing platform 632, the pushing plates 626 on both sides are respectively located on the left and right sides of the entire row of grey cloth rolls. At this time, the hydraulic cylinder 415 is continued to be started to make the loading platform 611 continue to descend with the connecting block 612 and compress the spring 615, and the height between the connecting block 612 and the lower pressure plate 614 changes, so that the angle between the connecting arm 621 and the connecting block 612 is enlarged, so that the left connecting arm 621 pushes the left end of the first slide plate 623 to the left, and the first slide plate 623 will bring the corresponding pushing plate 626 closer to the grey cloth roll, and at the same time, the right connecting arm 621 pushes the right end of the second slide plate 624 to the right, and the second slide plate 624 will bring the pushing plate 626 closer to the grey cloth roll, and after the connecting block 612 descends to a certain height, the pushing plates 626 on both sides will longitudinally extrude and position the entire row of grey cloth rolls.

[0043] See also Figure 1 , Figure 4 , Figure 5 and Figure 7 The locking portion 64 includes a matching cylinder 641, a screw sleeve 642, a fourth motor 643, a lock hole 644, a spring lock rod 645, a rounded block 646, a screw rod 647 and a docking cylinder 648. The four corners of the loading platform 611 are fixedly penetrated with matching cylinders 641, and a screw sleeve 642 is installed on the upper end of the matching cylinder 641 through a bearing. The screw sleeve 642 is fixedly sleeved with a third pulley, and the third pulleys are connected by a second belt transmission. The fourth motor 643 is fixedly installed on the loading platform 611, and the output end of the fourth motor 643 is connected to the output end of the fourth motor 643. A screw sleeve 642 is connected through the transmission of the third gear set. A plurality of locking holes 644 are opened in a circular array at the lower end of the matching cylinder 641. Spring locking rods 645 are slidably installed in the locking holes 644. A chamfered table block 646 is slidably installed in the matching cylinder 641. A screw rod 647 threadedly connected to the screw sleeve 642 is fixedly installed on the upper end of the chamfered table block 646. A docking cylinder 648 corresponding to the matching cylinder 641 is fixedly installed on the upper end surface of the force-bearing platform 632. A positioning hole matching the corresponding spring locking rod 645 is opened in the docking cylinder 648.

[0044] During specific operation, the to-be-pushed part 62 and the supporting part 61 cooperate to complete the longitudinal extrusion and positioning of the whole row of fabric rolls. At this time, the mating cylinder 641 on the loading platform 611 will be inserted into the docking cylinder 648 of the force-bearing platform 632. Then, the fourth motor 643 is started, and it rotates the corresponding screw sleeve 642 through the third gear set. The screw sleeve 642 rotates synchronously through the cooperation of the third pulley and the second belt, and drives the round frustum block 646 to descend in the mating cylinder 641 through the lead screw 647. After descending a certain distance, the spring lock rod 645 will be extruded from the lock hole 644 and inserted into the positioning hole, so as to lock the positions of the loading platform 611 and the force-bearing platform 632, thus ensuring that the two pushing plates 626 always extrude the whole row of fabric rolls.

[0045] Then, the second motor 524 is started in reverse to release the locking of the C-shaped carrier 636. At this time, the hydraulic cylinder 415 can be started in reverse to drive the fixed force-bearing platform 632 to rise. The force-bearing platform 632 will lift the whole row of fabric rolls through the two C-shaped carriers 636 on both sides. During the rising process, the third motor 635 is started, and it rotates the second bidirectional screw 633 through the second gear set, so as to drive the two C-shaped carriers 636 on both sides to approach each other and extrude and position the whole row of fabric rolls horizontally. When the telescopic end of the hydraulic cylinder 415 retracts to a certain extent, the hydraulic pump is stopped, thus completing the positioning and clamping of the fabric rolls, reducing the gaps between the stacked fabric rolls, and improving the overall tightness of the stacking.

[0046] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown in, the loading part 42 includes a supporting frustum 421, a connecting shaft 422 and a loading platform 423. The supporting frustum 421 is fixedly installed on the upper end surface of the base 1 in front of the supporting cylinder base 2. The connecting shaft 422 is installed at the center of the upper end surface of the supporting frustum 421 through a bearing, and the loading platform 423 is fixedly installed at the upper end of the connecting shaft 422.

[0047] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown in, the intermittent part 43 includes a first pulley 431, a rotating cylinder 432 and a first belt 433. The first pulley 431 is fixedly sleeved on the column 412. A rotating cylinder 432 coaxial with the connecting shaft 422 is installed between the supporting frustum 421 and the loading platform 423 through a bearing. A ratchet and pawl mechanism is arranged between the rotating cylinder 432 and the connecting shaft 422. A second pulley is fixedly sleeved on the outer wall of the rotating cylinder 432. The first pulley 431 and the second pulley are传动连接driven by the first belt 433 provided.

[0048] It should be noted that there is an error in the original text where "传动连接driven by" should be "driven and connected by". The above translation has been corrected accordingly.During specific operation, after the clamping mechanism 6 completes the clamping of the entire row of fabric rolls, first place the material carrier plate for carrying the fabric rolls at the center of the material loading table 423, and start the first motor 413 to rotate the column 412 through the first gear set, so as to drive the entire row of clamped fabric rolls forward by 90 degrees through the support arm 414. At this time, the column 412 will drive the rotating cylinder 432 to rotate under the cooperation of the first pulley 431, the second pulley and the first belt 433. The ratchet teeth inside the rotating cylinder 432 are in forward contact with the pawls on the connecting shaft 422, so that the rotating cylinder 432 will not rotate the connecting shaft 422. When the support arm 414 moves above the material loading table 423, stop the operation of the first motor 413. At this time, the clamping mechanism 6 is located directly above the material carrier plate.

[0049] Subsequently, start the hydraulic pump to lower the clamping mechanism 6, so as to place the entire row of fabric rolls on the material carrier plate. Then, reverse-start the third motor 635 to move the U-shaped carrier frames 636 on both sides to the two sides until the U-shaped carrier frames 636 no longer contact the two ends of the fabric rolls. Subsequently, reverse-start the fourth motor 643 to release the locking of the load platform 611 and the force-bearing platform 632. At this time, the load platform 611 will drive the connecting block 612 and the lower pressing plate 614 to rise in sequence, so as to release the extrusion of the fabric rolls by the two pushing plates 626 on both sides. At the same time, continue to rise to drive the force-bearing platform 632 to rise through the limit disk at the upper end of the second slide rod 631, and completely lift the clamping mechanism 6. At this time, the positioning and stacking of a group of fabric rolls are completed.

[0050] Subsequently, reverse-start the first motor 413 to drive the support arm 414 to return the clamping mechanism 6 to its original position. At this time, the ratchet teeth inside the rotating cylinder 432 are in reverse contact with the pawls on the connecting shaft 422, so as to automatically drive the loading plate on the material loading table 423 to rotate backward by 90 degrees, so that the fabric rolls of the next group and the previous group are stacked in a perpendicular state to each other, thereby reducing the complexity and time of manual operation and realizing the continuous operation of stacking.

[0051] After the clamping mechanism 6 is reset, start the hydraulic pump again to lower the clamping mechanism 6, so that the U-shaped carrier frames 636 are respectively placed on their respective matching support blocks 521. Then, start the third motor 635 to reset the U-shaped carrier frames 636, so that the stacking of the next group of fabric rolls can be continued.

[0052] Please refer to Figure 1 — Figure 7 The working principle: When it is necessary to position and stack the fabric rolls, start the second motors 524 on both sides to fix the U-shaped carrier frames 636 on the matching support blocks 521 through the matching part 52 and the hoisting part 63. Then, place the fabric rolls on the conveying belt 513 one by one through an external manipulator. Then, start the external motor to transport the fabric rolls to between the symmetric U-shaped carrier frames 636 at the front and back through the conveying part 51.

[0053] Subsequently, the hydraulic cylinder 415 is started, and the supporting part 61 and the pushing part 62 cooperate to longitudinally extrude and position the whole row of fabric rolls. Then, the loading platform 611 and the force-bearing platform 632 are locked by the locking part 64, and the second motor 524 is started in the reverse direction to release the locking of the C-shaped carrier 636. Subsequently, the hydraulic cylinder 415 is started in the reverse direction to drive the fixed force-bearing platform 632 to rise. During the rising process, the whole row of fabric rolls is extruded and positioned horizontally through the hoisting part 63, and the hydraulic pump stops operating when the telescopic end of the hydraulic cylinder 415 retracts to a certain extent.

[0054] Then, the loading plate is placed at the center of the loading table 423, and the first motor 413 is started. Through the rotating part 41, the whole row of fabric rolls is rotated forward by ninety degrees. When the support arm 414 moves above the loading table 423, the hydraulic pump is started to lower the clamping mechanism 6, and the whole row of fabric rolls is placed on the loading plate. Then, the third motor 635 is started in the reverse direction so that the C-shaped carrier 636 no longer contacts the two ends of the fabric roll. Subsequently, the fourth motor 643 is started in the reverse direction to release the locking, and the loading platform 611 will drive the connecting block 612 and the lower pressing plate 614 to rise in sequence, thereby releasing the extrusion of the two side pushing plates 626 on the fabric roll. At the same time, it continues to rise, and the force-bearing platform 632 is driven to rise through the limit disc at the upper end of the second sliding rod 631, thus completely lifting the clamping mechanism 6. At this time, the positioning and stacking of a group of fabric rolls are completed.

[0055] Subsequently, the first motor 413 is started in the reverse direction so that the support arm 414 drives the clamping mechanism 6 to return to the original position, thereby driving the loading plate on the loading table 423 to automatically rotate backward by ninety degrees. After the clamping mechanism 6 is reset, the hydraulic pump is started again to lower the clamping mechanism 6 so that the C-shaped carrier 636 is respectively placed on its respective matching support blocks 521. Then, the third motor 635 is started to reset the C-shaped carrier 636, and in this way, the stacking of the next group of fabric rolls can be continued.
