Abstract
Description
Technical Field
[0001] This invention relates to the field of textile technology, and in particular to an automatic reed threading mechanism. Background Technology
[0002] Before the yarn is woven on the loom, it needs to undergo a preparatory process called warping. The reed-threading mechanism is an important component of the warping machine, and its structural form, motion precision, and stability directly affect the efficiency, speed, and quality of warping. The warping machine needs to sequentially pass the yarn through the warp holes of the stop warp, the heddle eyes of the heddles, and the gaps between the reed teeth. Therefore, the reed-threading mechanism needs to install the reed onto the reed-threading base and discharge the reed after it has been threaded, so that it can be used for the next threading cycle. Currently, the reed-threading process is mostly done manually, which is slow and inefficient. Summary of the Invention

The two movable rods pass through the through hole to connect with the movable end of the corresponding push-pull electromagnet switch. The two movable rods can move left and right under the action of the two push-pull electromagnet switches, thereby driving the connecting rod closer to or away from the support rod. The movable component and the support rod together form a clamping groove to clamp the reed.
[0022] Optionally, the automatic reed threading mechanism further includes a flipping mechanism located between the upper reed station and the output station, the flipping mechanism comprising:
[0023] The base plate is fixed to the frame.

[0049] The pickup unit is located at the upper end of the second support plate.
[0050] In the technical solution of this invention, stacked reeds are placed on the top reed plate. The up-and-down movement of the top reed plate allows the height of the uppermost reed to match that of the pushing part, thus enabling a feeding action via a flat pushing motion. The picking part picks up the reeds removed from the top reed plate and, starting from the output station, first passes through the image detection mechanism to obtain the reed tooth spacing of the reed picked up by the picking part, thereby adjusting the spacing between two adjacent hooks in the hook assembly accordingly. When the picking part carries the reed to the reed-threading station, it drives... The hook assembly moves to cooperate with the stationary reed to complete the reed threading. At this time, the pickup part remains in a fixed position, and the reed that has been threaded is moved from the threading station to the reed-stopping station by the multiple directions of the clamping part, thus completing the whole process. The automatic feeding of the reed can automatically thread the next reed after threading one reed, and can realize the simultaneous threading of multiple reed teeth, reducing the number of times a single reed needs to be threaded, saving threading time, improving efficiency, greatly reducing the difficulty of manual operation, and improving the production efficiency of the warping machine.

[0067] Before the yarn is woven on the loom, it needs to undergo a preparatory process called warping. The reed-threading mechanism is an important component of the warping machine, and its structural form, motion precision, and stability directly affect the efficiency, speed, and quality of warping. The warping machine needs to sequentially pass the yarn through the warp holes of the stop warp, the heddle eyes of the heddles, and the gaps between the reed teeth. Therefore, the reed-threading mechanism needs to install the reed onto the reed-threading base and discharge the reed after it has been threaded, so that it can be used for the next threading cycle. Currently, the reed-threading process is mostly done manually, which is slow and inefficient.
[0068] In view of this, the present invention provides an automatic reed threading mechanism. Figures 1 to 8 This is an embodiment of the automatic reed threading mechanism provided by the present invention.
[0069] Please refer to Figures 1 to 3The automatic reed-threading mechanism 100 includes a frame 1, an automatic reed-feeding mechanism 2, a reed-picking mechanism 3, an image detection mechanism 4, a reed-threading mechanism 5, a clamping mechanism 6, and a transfer mechanism. The frame 1 has a reed-feeding station 1a, an output station 1b, a reed-threading station 1c, and a reed-stopping station 1d. The reed-feeding station 1a and the output station 1b are arranged in a front-to-back direction, while the output station 1b, the reed-threading station 1c, and the reed-stopping station 1d are arranged in a left-to-right direction. The automatic reed-feeding mechanism... Structure 2 includes a top reed plate 21 and a pushing part 22. The top reed plate 21 is disposed at the upper reed station 1a and has a vertical travel. The upper surface of the top reed plate 21 is used to hold multiple reeds. The pushing part 22 can move in the front-back direction to push the multiple reeds from the top reed plate 21 sequentially. The reed picking mechanism 3 includes a picking part 31 disposed on the frame 1 for picking up the reeds removed from the top reed plate 21. The picking unit 31 is movable between the output station 1b and the reed-threading station 1c; the image detection mechanism 4 is located between the output station 1b and the reed-threading station 1c, and is used to detect the spacing between the reed teeth of the reed picked up by the picking unit 31; the reed-threading mechanism 5 includes a hook group 51 movably mounted in the front-back direction, the hook group 51 being movable to the reed-threading station 1c, and the spacing between two adjacent hooks in the hook group 51 is adjusted according to the detection result of the image detection mechanism 4. The distance is such that it cooperates with the reed to complete the reed threading during the movement of the hook assembly 51; the clamping mechanism 6 includes a clamping part that can move in the left-right direction and in the front-back direction, thereby transferring the threaded reed from the threading station 1c to the reed stopping station 1d; the transfer mechanism includes a first transfer component 71 and a second transfer component 72, the second transfer component 72 is used to drive the clamping part to move, and the first transfer component 71 is used to drive the pickup part 31 to move.
[0070] In the technical solution of this invention, stacked reeds are placed on the top reed plate 21. The vertical movement of the top reed plate 21 allows the height of the uppermost reed to match that of the pushing part 22, thus enabling a feeding action via a horizontal pushing motion. The picking part 31 picks up the reeds removed from the top reed plate 21 and, starting from the output station 1b, first passes through the image detection mechanism 4 to obtain the reed tooth spacing of the reed picked up by the picking part 31, thereby adjusting the spacing between two adjacent hooks in the hook group 51 accordingly. When the picking part 31 carries the reed to the reed threading work... Position 1c drives the hook assembly 51 to move, thereby cooperating with the stationary reed to complete the reed threading. At this time, the pickup part 31 keeps its position fixed, and the reed that has been threaded is moved from the reed threading position 1c to the reed stopping position 1d through the multiple directions of the clamping part, thus completing the whole process. The automatic feeding of the reed can automatically thread the next reed after threading one reed, and can realize the simultaneous threading of multiple reed teeth, reducing the number of times a single reed is threaded, saving threading time and improving efficiency, greatly reducing the difficulty of manual operation, and improving the production efficiency of the warping machine.
[0071] Considering that stacked materials are prone to shaking and misalignment under external forces, in order to ensure stable feeding of the reed, please refer to the following in this embodiment. Figure 3The automatic reed feeding mechanism 2 further includes a reed box 23, a baffle 24, and a first cylinder 25. The reed box 23 is fixed to the frame 1 and is located at the upper reed station 1a. The upper end of the reed box 23 is open. The baffle 24 is located above the reed box 23 and forms a discharge gap with the reed box 23. The first cylinder 25 is located on the side of the reed box 23 facing away from the output station 1b and has... The top reed plate 21, which has a cylinder rod extending in the front-rear direction, is disposed inside the reed box 23, and the lower end of the top reed plate 21 is connected to the bottom wall of the reed box 23 by multiple springs; the pusher part 22 is plate-shaped and fixed to the cylinder rod of the first cylinder 25, and can move through the discharge gap so that it contacts the reed exposed in the discharge gap and pushes it out during the movement of the first cylinder 25. The reed box 23 functions as a material box, limiting the movement of materials through its side walls. It serves both to hold materials and prevent them from shifting. The baffle 24 acts as an upper limit, preventing the reeds from overstepping their designated position. Initially, with a large number of reeds, the springs are compressed, and the distance between the top reed plate 21 and the bottom wall of the reed box 23 is small. At this time, the uppermost reed is fully exposed in the discharge gap, allowing it to be pushed out by the plate-shaped pusher 22 without being obstructed by the reed box. The obstruction of the side wall 23 reduces the pressure on the spring as the number of reeds decreases, causing the spring length to change adaptively. This enables the top reed plate 21 to automatically move up and down, ensuring that there are always reeds exposed in the discharge gap, thus enabling continuous feeding. Since the pushing part 22 moves in a straight line, the first cylinder 25 is selected as the drive for consideration of installation space and driving convenience. In other embodiments, other components can be used instead, and the present invention does not limit this.
[0072] It should be understood that side plates that can extend and retract vertically can also be provided around the top reed plate 21 to achieve the enclosure function. The top reed plate 21 can also be actively displaced by means of a cylinder drive. This invention does not limit this.
[0073] The present invention does not limit the structural form of the picking part 31, as long as the picking action is completed. It can be done by means of adsorption, clamping, etc. It is necessary to consider that it should not block the reed so as not to hinder the subsequent reed threading action.
[0074] In this embodiment, please refer to Figure 4The pickup unit 31 includes a base plate 311, two push-pull electromagnet switches 312, and a movable component. The base plate 311 is drivenly connected to the second transfer assembly 72. The base plate 311 has a support rod extending vertically along one side in the left-right direction. One of the two push-pull electromagnet switches 312 is located on the base, and the other is located on the support rod. The side of the support rod has two through holes spaced vertically. The movable component includes a connecting rod 3131 extending vertically and two movable rods 3132 located at the upper and lower ends of the connecting rod 3131 and extending horizontally. The two movable rods 3132 pass through the through holes to connect with the movable ends of the corresponding push-pull electromagnet switches 312. The two movable rods 3132 can move left and right under the action of the two push-pull electromagnet switches 312, thereby driving the connecting rod 3131 closer to or away from the support rod. The movable component and the support rod together form a clamping groove to clamp the reed. The push-pull electromagnet switch has a movable part exposed in its housing. The movable part can be controlled to push and pull by controlling the current. It is mostly used to control lock cylinders and valves, where it plays the role of providing driving force to drive the C-shaped movable part to move. Since the reed is located in the clamping groove surrounded by the movable part and the support rod, it can accommodate different specifications of reeds within a certain size range. The through hole cooperates with the movable rod 3132 to realize the movement guidance. This control method has a faster response speed and is more flexible. Moreover, the push-pull electromagnet switch 312 is inexpensive, occupies little space, is easy to purchase, and reduces costs.
[0075] Based on the above embodiments, due to the structural arrangement of the movable parts of the pickup unit 31, the reed is required to be vertical when entering the output station 1b, while its posture is horizontal when discharging. Although the orientation and height difference between the two can be set, the posture after falling is not stable. Therefore, in one embodiment, please refer to... Figure 5 The automatic reed threading mechanism 100 further includes a flipping mechanism 8 located between the upper reed station 1a and the output station 1b. The flipping mechanism 8 includes a fixed base plate 81, a flipping plate 82, and a second cylinder. The fixed base plate 81 is fixed to the frame 1. The flipping plate 82 is inclined downwards towards the output station 1b. The lower end of the flipping plate 82 is hinged to the fixed base plate 81, and the upper end of the flipping plate 82 corresponds to the top reed plate 21. The fixed end of the second cylinder is located on the fixed base plate 81, and the movable end of the second cylinder is connected to the flipping plate 82. After the reed on the top reed plate 21 is pushed down, it naturally falls onto the inclined flipping plate 82. Controlling the flipping plate 82 to rotate to a vertical position transforms the reed's posture to vertical, allowing it to be picked up by the pickup unit 31, thus ensuring the stability of the material transfer process.
[0076] It is understood that the second cylinder is preferably tilted to adapt to the orientation of the flip plate 82.
[0077] Furthermore, the present invention does not limit the specific form of the image detection mechanism 4. It can employ a CCD visual detection 55 or other forms. Considering the environment and image clarity, in this embodiment, please refer to... Figure 6 The image detection mechanism 4 includes a housing 41, a light source 42, and a camera 43. The housing 41 is fixed to the frame 1. The housing 41 has two opposing openings 411 on its front and rear side walls for the pickup unit 31 to pass through. The light source 42 is located inside the housing 41 and can be an LED light or other illumination source, primarily to ensure brightness within the housing 41. The camera 43 is fixed inside the housing 41, avoiding contact with the light source 42, and is used to capture images when the pickup unit 31 enters the housing 41. Since the housing 41 is a relatively enclosed environment, there is no need to worry about the camera 43's images being affected by the environmental background, nor is there a need for accurate measurement of the reed tooth spacing. It should be understood that the positions of the two openings 411 should be aligned with the travel distance of the pickup unit 31, allowing the pickup unit 31 to naturally complete the detection during travel using its original driving mechanism.
[0078] For further details, please refer to... Figure 2 and Figure 7 The reed threading mechanism 5 includes a support 52, a slide rail 53, and a third cylinder 54. The support 52 is mounted on the frame 1, and its position should not obstruct the movement of the pickup part 31. The slide rail 53 is located on the upper surface of the support 52 for guidance. The slide rail 53 can be a grooved structure or a raised track structure. In this embodiment, a grooved structure is used to facilitate the positioning of the hook assembly 51. The third cylinder 54 is fixed to the side of the support 52 facing away from the reed threading station 1c. The cylinder rod of the third cylinder 54 can extend in the front-back direction. The hook assembly 51 slides along the slide rail 53 and is fixedly connected to the cylinder rod of the third cylinder 54. The bottom of the support 52 is supported by a pillar or support rod and can be fixed by bolts. The straight hook assembly 51 is driven by a linear drive and a linear guide, and each hook has yarn hooked on it.
[0079] It is understandable that, for ease of arrangement, in this embodiment, the reed threading mechanism 5 is located on the side of the reed threading station 1c facing away from the upper reed station 1a, so that it can be arranged separately from other components.
[0080] Furthermore, the reed threading mechanism 5 also includes a vision detection structure 55 disposed on the frame 1 for detecting the position of the pickup unit 31. In this embodiment, the vision detection structure 55 also takes the form of a camera 43, which can be disposed on the support 52 or fixed on the frame 1.
[0081] This invention does not limit the specific form of the clamping mechanism 6; clamping can be achieved through a robotic arm or suction cup, etc. In this embodiment, please refer to... Figure 8 The clamping mechanism 6 includes a connecting seat, a fourth cylinder 61, and a finger cylinder 62. The connecting seat, driven by the second transfer assembly 72, can move along the front-to-back direction on the frame 1 and is located above the pickup part 31. The fourth cylinder 61 is disposed on the connecting seat, and its cylinder rod can extend along the front-to-back direction. The finger cylinder 62 is connected to the cylinder rod of the fourth cylinder 61 via a connector. Each of the two finger parts of the finger cylinder 62 is provided with a clamping piece 63, which is used to jointly clamp the reed after it has been threaded. In this structure, the second transfer assembly 72 drives the connecting seat to move linearly in one direction, the fourth cylinder 61 moves linearly in the other direction, and the two finger parts of the finger cylinder 62, due to their structural characteristics, can move closer or further apart. By installing the clamping pieces 63 as clamping parts, the clamping pieces 63 can increase the contact area with the reed, improve the clamping stability, and thus realize the clamping and transfer function.
[0082] This invention does not limit the driving method of the second transfer component 72. It can be configured as a linear drive module, cylinder, belt sprocket, or other structures. In this embodiment, the second transfer component 72 includes a first lead screw structure, a first guide rail, and a first support plate. The first lead screw structure is arranged in a left-right direction and includes a bearing seat, a rail, a nut seat, a lead screw nut, and a lead screw. The bearing seat is fixed to the top plate of the frame 1. Both ends of the lead screw are inserted into the bearing seat. The lead screw nut is sleeved on the lead screw, and the nut seat is sleeved on the lead screw nut. The upper end of the first support plate is fixed to the nut seat of the first lead screw structure and slidably mounted on the first guide rail. The clamping mechanism 6 is located at the lower end of the first support plate. It can be understood that a guide rail slider can be provided on the first support plate for easy sliding cooperation, or a guide rail slider can be directly provided on the first guide rail and fixed to the first support plate. This achieves stable transmission and ensures linear drive.
[0083] It should be understood that the structures of the first transfer component 71 and the second transfer component 72 can be the same or different. In this embodiment, the two are set to have the same structure, both being driven by a lead screw and a guide rail. However, since the clamping part is located above and the picking part 31 is located below, the installation foundation and setting position are different during arrangement. Specifically, the first transfer component 71 includes a second lead screw structure, a second guide rail, and a second bearing plate. The second lead screw structure is arranged in the left-right direction, and the seat of the second lead screw structure is fixed to the bottom of the frame 1. The second guide rail extends in the left-right direction and is fixed to the bottom of the frame 1, and is spaced apart from the lead screw of the second lead screw structure in the front-back direction. The lower end of the second bearing plate is fixed to the nut seat of the second lead screw structure and is slidably mounted on the second guide rail. The picking part 31 is located at the upper end of the second bearing plate.
[0084] In addition, to drive the two lead screw structures, the automatic reed threading mechanism 100 also includes two sets of servo drive mechanisms. Each servo drive mechanism includes a servo motor, a reducer, a coupling, and a mounting side plate. The servo motor is connected to the reducer, and the reducer is connected to the coupling and fixed on the mounting side plate, used to drive the first lead screw structure and the second lead screw structure to move respectively.
[0085] To reduce weight and facilitate assembly, the frame 1 is constructed from multiple steel plates, multiple square tubes, multiple side plates, and support blocks for connection, forming a partially open box-like structure.
[0086] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
