Abstract
Description
Technical Field
[0001] This invention relates to the field of yarn roll feeding technology, and more specifically, to a combined yarn roll supply system and an automatic yarn roll feeding system. Background Technology
[0002] Yarn rolls are whole rolls of twisted yarn used in fabric production. The traditional production process involves manually moving stacks of yarn rolls to a predetermined position using forklifts, followed by various steps such as unstacking, stacking, and loading. This process wastes a lot of manpower and increases production costs.
[0003] Therefore, the patentee designed Chinese patent application number "202320041464.1" entitled "A Yarn Roll Stacking Supply System and an Automatic Yarn Roll Feeding System." However, extensive field research revealed that after the equipment fed the yarn rolls to the looms, it was sufficient for the looms to weave continuously for several days without needing to feed more yarn rolls. This resulted in the yarn roll supply system being idle for extended periods, significantly wasting production resources.
[0004] In view of this, the applicant hereby submits this application after studying the existing technology. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0027] Example 1
[0028] Depend on Figures 1 to 8 As shown, an embodiment of the present invention provides a combined yarn roll supply system, which includes a yarn roll stack moving device 9, a pallet stacking device 1, a fixing device 11, and a feeding device 10 connected to the fixing device 11.
[0029] The feeding device 10 includes a movable base 29, a control component 28 engaged with the movable base 29, and a robotic arm 26. The robotic arm 26 is electrically connected to the control component 28.
[0030] The fixing device 11 includes a fixed base 31, a clamping slider 47 movably disposed on the fixed base 31, and a first driving assembly 30 for driving the clamping slider 47 to slide. A clamping gap 40 is formed between the clamping slider 47 and the fixed base 31 for clamping the movable base 29.
[0031] The yarn roll stack moving device 9 is located next to the fixed device 11 and is used to move the pallet at the yarn roll stack loading station, the yarn roll stack unloading station, and the pallet recycling station.
[0032] A pallet stacking device 1 is used to move empty pallets from the pallet recycling station to the pallet stacking station. The pallet stacking device 1 includes a truss assembly 4 located at the end of the yarn roll stacking moving device 9, a first moving assembly 3 movable horizontally on the truss assembly 4, a second moving assembly 2 movable vertically on the first moving assembly 3, and a gripping assembly 5 on the second moving assembly 2. The gripping assembly 5 includes a gripping seat 7 on the bottom of the second moving assembly 2, a gripper 8 movably disposed on the gripping seat 7, and a first driving member 6 disposed between the gripper 8 and the gripping seat 7. The first driving member 6 drives the gripper 8 to grasp or release the pallet. The first moving assembly 3 and the second moving assembly 2 move the gripping assembly 5 between the pallet recycling station and the pallet stacking station.
[0033] Specifically, the yarn roll stacking moving device 9 is configured to simultaneously accommodate at least two yarn roll stacks and one empty pallet, i.e., it includes three stations: a yarn roll stack loading station, a yarn roll stack unloading station, and a pallet recycling station. Workers use a forklift to place the yarn roll stacks at the loading station. The yarn roll stacking moving device 9 moves the yarn roll stacks to the unloading station, where the loading device 10 performs the unloading operation, loading the yarn rolls from the stack onto a dedicated loading robot that places the yarn rolls onto the assembly line.
[0034] Once all the yarn rolls on the yarn roll stack at the unstacking station are loaded, and all the foam boards have been transferred by the feeding device 10 to the designated foam board pallet, only one empty pallet remains on the original yarn roll stack. At this point, the yarn roll stack moving device 9 moves the empty pallet to the pallet recycling station, and simultaneously moves a new yarn roll stack to the yarn roll stack unstacking station of the yarn roll stack moving device 9 to continue the unstacking operation. Meanwhile, the pallet stacking device 1 can move the empty pallet from the pallet recycling station to the pallet stacking station for stacking.
[0035] The process involves the simultaneous movement of empty pallets and new yarn roll stacks, which takes far less time than manually replacing empty pallets with yarn roll stacks. This saves equipment waiting time, greatly improves production efficiency, and eliminates the need for manual monitoring of the remaining material in the yarn roll stacks, making it highly practical.
[0036] Based on the above embodiments, in an optional embodiment of the present invention, the combined yarn roll supply system further includes a control device. The control device is electrically connected to the control component 28, the yarn roll stack moving device 9, and the pallet stacking device 1.
[0037] The control device includes a processor, a memory, and a computer program stored in the memory; the computer program can be executed by the processor to perform the following steps:
[0038] S1. When it is determined that there is a yarn roll stack at the yarn roll stack loading station, control the yarn roll stack moving device 9 to move the yarn roll stack to the yarn roll stack unloading station.
[0039] S2. The yarn rolls are photographed and positioned by a 3D camera mounted on the robotic arm 26 to determine the first center position of each yarn roll.
[0040] S3. Grab the yarn roll according to the first center position.
[0041] S4. The yarn roll frame on the loading robot is photographed and positioned by a 3D camera mounted on the robotic arm 26 to determine the second center position of the yarn roll.
[0042] S5. Based on the second center position, place the yarn roll onto the yarn roll shaft and stack it.
[0043] S6. When it is determined that all yarn rolls in one layer have been stacked, the robotic arm 26 uses a suction cup mechanism to pick up the foam board between the yarn roll layers and moves the foam board to the pallet where it is placed. The foam boards are then manually removed once they reach a certain height.
[0044] S7. When it is determined that all the yarn rolls and foam boards on the yarn roll stack have been removed (i.e., only one empty pallet remains at the yarn roll stack unstacking station), control the yarn roll stack moving device 9 to move the empty pallet at the yarn roll stack unstacking station to the pallet recycling station, and at the same time move the yarn roll stack at the yarn roll stack loading station to the yarn roll stack unstacking station.
[0045] S8. When it is determined that the foam boards have been stacked to the first preset height, or when it is determined that the empty pallets have been stacked to the second preset height, a message is sent to notify the workers so that they can be removed in time.
[0046] Specifically, the detachable feeding device 10 allows the equipment to be moved to other production lines for feeding after feeding is completed on one production line, which greatly improves the utilization rate of the equipment and reduces the production cost of the factory.
[0047] like Figures 5 to 8 As shown, in an optional embodiment of the present invention, based on the above embodiments, the fixed base 31 is provided with a support plate 35. The support plate 35 is provided with a sliding channel 41. The clamping slider 47 is constructed in an "I" shape and is embedded in the sliding channel 41. The movable base 29 is provided with a clearance groove 33 for the clamping slider 47 to be inserted.
[0048] The feeding device 10 also includes a wear-resistant pad 34 disposed on the movable base 29. A clearance groove 33 is provided on the wear-resistant pad 34. The wear-resistant pad 34 is provided with an inclined support surface 32. The clamping slider 47 is provided with an inclined downward pressing surface 37. The inclined downward pressing surface 37 and the inclined support surface 32 cooperate with each other to press the movable base 29 toward the fixed base 31 when the clamping slider 47 moves toward the movable base 29.
[0049] Specifically, the clamping slider 47 with its "I"-shaped structure can clamp and wrap the support plate 35 and the movable base 29 in a C-shape on both sides, providing high connection strength and good stability. This prevents the feeding device 10 and the fixing device 11 from detaching.
[0050] like Figures 5 to 8 As shown, in an optional embodiment of the present invention based on the above embodiments, the first driving assembly 30 includes a driving base 50, a first telescopic member 45 and a first rotating member 49 hinged to the driving base 50, a first sliding member 46 slidably engaged with the driving base 50, and a first connecting member 48 with its two ends respectively hinged to the first rotating member 49 and the first sliding member 46. The first telescopic member 45 is hinged to the first rotating member 49 to drive the first rotating member 49 to rotate.
[0051] The first rotating member 49 and the driving base 50 are hinged to a first hinge axis 44, the first rotating member 49 and the first connecting member 48 are hinged to a second hinge axis 43, and the first connecting member 48 and the first sliding member 46 are hinged to a third hinge axis 42. The first driving assembly 30 is configured such that when the clamping slider 47 clamps the movable base 29, the height of the second hinge axis 43 is not higher than the plane containing the first hinge axis 44 and the third hinge axis 42.
[0052] The specific meaning of "the height of the second hinge axis 43 is not higher than the plane containing the first hinge axis 44 and the third hinge axis 42" is as follows: When the clamping slider 47 releases the movable base 29, the second hinge axis 43 is on one side of the plane containing the first hinge axis 44 and the third hinge axis 42. When the clamping slider 47 clamps the movable base 29, the second hinge axis 43 is on the other side of the plane containing the first hinge axis 44 and the third hinge axis 42, or the second hinge axis 43 is on the plane containing the first hinge axis 44 and the third hinge axis 42.
[0053] Specifically, the first rotating component 49 is constructed as an L-shaped or T-shaped structure. In the crank-connecting rod structure of this embodiment, a mechanical dead point is formed between the first hinge shaft 44, the second hinge shaft 43, and the third hinge shaft 42 when locked. Even if the clamping slider 47 is subjected to force, the first driving component 30 will not loosen the movable base 29 and the support plate 35, nor will it become loose, thus effectively locking the two together firmly.
[0054] like Figures 5 to 8 As shown, in an optional embodiment of the present invention, based on the above embodiments, the fixing device 11 further includes a positioning pin 38, a guide block 36 disposed on the fixed base 31, and a safety pin 39 to prevent the movable base 29 from detaching from the fixed base 31.
[0055] The control component 28 is provided with a first power quick connector and a first air supply quick connector. The fixing device 11 further includes a second power quick connector and a second air supply quick connector disposed on the fixing base 31. The first power quick connector and the second power quick connector are compatible. The first air supply quick connector and the second air supply quick connector are compatible.
[0056] The loading device 10 also includes a plurality of forklift support members 27 disposed on the movable base 29 for loading by forklifts.
[0057] Specifically, the steps for fixing the feeding device 10 to the fixing device 11 are as follows:
[0058] A1. The loading device 10 is moved to the fixed device 11 by a forklift so that the movable base 29 is embedded in the limiting space enclosed by the guide block 36 and the positioning pin 38 is embedded in the movable base 29.
[0059] A2. Control the first drive assembly 30 to drive the clamping slider 47 to move toward the movable base 29 so as to clamp the movable base 29 and the support plate 35 together.
[0060] A3. Secure the safety pin 39 to the safety lock position.
[0061] A4. Connect the first power quick connector and the second power quick connector, and connect the first air source quick connector and the second air source quick connector.
[0062] like Figure 4 As shown, based on the above embodiments, in an optional embodiment of the present invention, the yarn roll stacking moving device 9 includes at least three third moving components 16 arranged sequentially. The at least three third moving components 16 are respectively located at the yarn roll stack loading station, the yarn roll stack unloading station, and the pallet recycling station. Specifically, configuring the yarn roll stacking moving device 9 as a structure consisting of multiple third moving components 16 connected sequentially facilitates the production and upgrading of the yarn roll stacking moving device 9. Preferably, each third moving component 16 can just support one pallet, allowing the length of the yarn roll stacking moving device 9 to be freely selected according to actual production needs.
[0063] The yarn roll stack moving device 9 further includes a limiting component 12 and at least two positioning components 13. The limiting component 12 is disposed at the end of the third moving component 16 located at the pallet recycling station. The at least two positioning components 13 are respectively disposed at the two third moving components 16 located at the yarn roll stack loading station and the yarn roll stack unstacking station.
[0064] The limiting component 12 includes a baffle 25 disposed on the third moving component 16. The positioning component 13 includes a first stop 14 disposed on the third moving component 16 and movable up and down, and a second telescopic member 15 engaged with the first stop 14. The second telescopic member 15 is used to drive the first stop 14 to move up and down, thereby positioning or avoiding the yarn roll stack.
[0065] Specifically, the first stop 14 is driven to move upward by the second telescopic member 15 so that it abuts against the yarn roll stack when it moves over, thereby positioning the yarn roll stack at the preset position of the conveying component for coarse positioning of the yarn roll stack.
[0066] like Figure 4As shown, based on the above embodiments, in an optional embodiment of the present invention, the third moving component 16 includes a conveying base 24, two first baffles 23 respectively disposed on both sides of the conveying base 24, at least two support seats 22 disposed parallel to and spaced apart from the conveying base 24, a second sliding member 21 slidably disposed on the support seats 22, and a third motor drively connected to the second sliding member 21. The ends of the first baffles 23 are configured as flared openings. Preferably, the number of third moving components 16 is three. The yarn roll stacking moving device 9 also includes two first guide members 20 disposed on the third moving component 16. The two first guide members 20 are configured as upward flared openings.
[0067] Specifically, the worker needs to place the yarn roll stack on the first third moving assembly 16, which then moves it. Therefore, a first guide 20 is installed on the first third moving assembly 16, giving it an upward flared structure to facilitate the worker placing the yarn roll stack on the first third moving assembly 16.
[0068] like Figures 1 to 3 As shown, based on the above embodiments, in an optional embodiment of the present invention, the truss assembly 4 includes a truss body 17 with a moving channel, and at least three second guide members 19 located in the moving channel. The at least three second guide members 19 are arranged around the pallet stacking station and form openings communicating with the exit of the moving channel. Each second guide member 19 has an upwardly inclined guide surface. The end of the yarn roll stacking moving device 9 is located in the moving channel.
[0069] The gripping assembly 5 includes two symmetrically arranged grippers 8 and two first driving members 6. The two grippers 8 are movably configured on the gripping base 7. The two first driving members 6 are respectively engaged with the two grippers 8 to drive the two grippers 8 to move closer or further apart. Each gripper 8 is provided with at least two insert portions 18 for insertion into slots at the bottom of the pallet. A clearance gap is provided between the at least two insert portions 18 to avoid the second guide member 19.
[0070] Specifically, the truss body 17 spans across the end of the yarn roll stacking moving device 9. Its length is at least greater than the length of two pallets, thereby moving the empty pallets on the yarn roll stacking moving device 9 to the pallet stacking station.
[0071] Preferably, the direction of the pallet stacking device 1 is perpendicular to the direction of the yarn roll stacking moving device 9, making the overall structure more compact. In other embodiments, the two can be set to the same direction, and the present invention does not specifically limit this.
[0072] Example 2
[0073] This application also provides an automatic yarn roll feeding system, which includes at least two weaving production lines and two combined yarn roll supply systems, as described in any paragraph of Embodiment 1, located on the two weaving production lines respectively. The two combined yarn roll supply systems share a single feeding device 10.
[0074] Specifically, since the fabric weaving production line can operate continuously for a long time after the yarn roll is loaded, sharing the feeding device 10 and the feeding robot between production lines can greatly save production line costs and has good practical significance.
[0075] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
