Technical Field
[0001] The utility model relates to a rapier loom with a multi-attachment control system, belonging to the field of rapier looms. Background Art
[0002] The leno fabric is centered on the weft yarn, and two warp yarns are alternately crossed and woven to form a mutually twisted shape, which improves the morphological stability of the fabric. The jacquard weave is that the warp yarns or weft yarns float on the fabric surface or interweave in a scattered manner according to the regular requirements, forming patterns or designs. Its pattern designs have many variations, which can enrich the varieties of fabrics. In the Chinese invention patent with the authorization announcement number CN106868686B and the name of "A rapier loom for weaving double-layer breathable fabrics", a rapier loom is disclosed, which can realize the leno weave and the jacquard weave on one device. The rapier loom includes a frame, a warp feeding component, a warp stop component, a warp guiding component, a weft inserting component, a jacquard component, a reset component, a coiling component and a driving component. The frame includes a front frame body and a rear frame body. The warp feeding component is arranged on the front frame body, and the warp guiding component, the weft inserting component, the jacquard component, the reset component and the coiling component are arranged on the rear frame body. The warp feeding component includes a first warp beam for winding and feeding the first warp yarns constituting the double-layer breathable fabric and a second warp beam for winding and feeding the second warp yarns constituting the double-layer breathable fabric. The warp guiding component includes a row of multiple independently operating first warp guiding components arranged in an array and a row of multiple independently operating second warp guiding components arranged in an array. The first warp guiding component is arranged at the previous working station of the second warp guiding component. The first warp guiding component is used to drive the first warp yarns to form a shed for inserting the weft yarns between the first warp yarns. The second warp guiding component is used to drive the second warp yarns to form a shed for inserting the weft yarns between the second warp yarns or to form a shed for inserting the weft yarns between the second warp yarns and the unit warp bundle composed of at least 2 first warp yarns. The rapier loom further includes a yarn separating component arranged at the previous working station of the warp guiding component. The yarn separating component is used to separate the horizontal positions of the first warp yarn a and the second warp yarn b and make the horizontal position of the second warp yarn b always lower than the horizontal position of the first warp yarn a when the second warp yarn b does not form a shed with the unit warp bundle. The yarn separating component includes a yarn pressing roller for pressing down the second warp yarn b, and the first warp yarn a is above the yarn pressing roller. If the second warp yarn and the first warp yarn are in the same yarn bundle during the conveying process, that is, the horizontal heights are almost the same, when a certain part of the second warp yarn is wound around a certain part of the first warp yarn to form the first shed, the adjacent part behind the second warp yarn, that is, the second warp yarn itself, will actually be lifted up comprehensively, and the adjacent part behind the first warp yarn, that is, the first warp yarn itself, will be lifted up comprehensively by the second warp yarn. Then when it is necessary to form the second shed after the first shed, the horizontal position of the first warp yarn has been affected and lifted, making it difficult for the second warp yarn to accurately change the relative height with the first warp yarn, and also making it difficult for the second warp yarn to alternately appear on the relative two sides of the first warp yarn, so that the second shed is difficult to form. And if the horizontal position of the second warp yarn during the conveying process is higher than that of the first warp yarn, the second shed will also be difficult to form.Therefore, in this weaving structure on the rapier loom, a yarn separating component is specially designed to control the horizontal positions of the first warp yarn and the second warp yarn, so as to ensure that the shed can be formed normally and accurately when the first warp yarn and the second warp yarn are wound around each other.
[0003] A yarn separating roller is used to control the horizontal positions of the first warp yarn and the second warp yarn. The separation gaps between the first warp yarns and the second warp yarns are fixed. When different yarns and fabrics require adjustment of the separation gaps, it is rather troublesome to replace the yarn separating roller. In addition, it is difficult to control the first warp yarns and the second warp yarns in different areas with the existing structure.
[0004] In addition, in a traditional rapier loom, the heald frames are used to detect whether the yarns are slack and adjust the tension. The lengths of the heald frames are generally the same, and it is difficult to control the tensions of different types of yarns differently.
[0005] Based on the above problems, the applicant has conducted research, thus giving rise to this case. Summary of the Utility Model

[0031] In order to better understand the technical solution of the present utility model, it will be described in more detail below in conjunction with embodiments.
[0032] Refer to Figure 1, A rapier loom with a multi-loom control system, comprising a frame (not shown in the figure), a warp feeding component, a warp stop component, a warp guiding component, a weft inserting component (not shown in the figure), a jacquard component, a reset mechanism, a coiling component, and a driving component (not shown in the figure). The warp feeding component includes a first warp beam 51 for winding and feeding the first warp yarn 41 and a second warp beam 52 for winding and feeding the second warp yarn 42. The first warp beam 51 is located below the second warp beam 52. These are the structures of existing rapier looms. For example, the corresponding structures in the background art patents can be adopted. The warp guiding component of the present invention includes a first warp guiding component 10 for driving the first warp yarn 41 to form a shed for inserting the weft yarn and a second warp guiding component 20 for driving the second warp yarn 42 to form a shed for inserting the weft yarn between the second warp yarns 42 or for the second warp yarns 42 to alternately form a shed for inserting the weft yarn between the opposite sides of a unit warp bundle composed of at least two of the first warp yarns 41 and the unit warp bundle. The first warp guiding component 10 and the second warp guiding component 20 can adopt the corresponding structures of the patents mentioned in the background art. The first warp guiding component 10 is used to guide the first warp yarn 41 for ordinary jacquard weaving, and the second warp guiding component 20 is used to guide the second warp yarn 42 for heddle weaving to achieve gauze weave. The present invention also includes a yarn separating mechanism 30 for separating the horizontal positions of the first warp yarn 41 and the second warp yarn 42. Different from using a yarn separating roller for yarn separation in the prior art, the yarn separating mechanism 30 of the present invention includes a plurality of yarn guiding parts 31 through which the first warp yarn 41 or the second warp yarn 42 is threaded. At the upper end of the yarn guiding part 31, there is a first lifting mechanism for driving the yarn guiding part 31 to move upward, and at the lower end of the yarn guiding part 31, there is a first reset mechanism 32 for driving the yarn guiding part 31 to reset downward. In the present invention, the yarn guiding parts 31, the first warp guiding component 10, and the second warp guiding component 20 are arranged in sequence along the running direction of the first warp yarn 41. In the present invention, there are a plurality of yarn guiding parts 31, and each yarn guiding part 31 is configured with a corresponding first lifting mechanism and a first reset mechanism 32. By the first lifting mechanism, the corresponding yarn guiding part 31 is lifted upward, so that the corresponding first warp yarn 41 or the second warp yarn 42 can be lifted upward. When the first lifting mechanism releases the lifting of the yarn guiding part 31, the first reset mechanism 32 can make the yarn guiding part 31 reset.

A stop beam 71 for installing the stop sensor 80 is provided on the stop frame 70. The stop piece 60 is sleeved on the stop beam 70. The stop piece 60 is supported by the first warp yarn 41 and the second warp yarn 42 when they are tensioned, and is separated from the stop sensor 80. The stop piece 60 loses its support and contacts the stop sensor 80 when the first warp yarn 41 or the second warp yarn 42 breaks or is overly relaxed. The stop piece 60 includes at least a first stop piece 61 and a second stop piece 62 with different weights. Specifically, the stop piece 60 is provided with an upper through hole 602 for the stop beam 71 to pass through and a lower through hole 601 for the first warp yarn 41 and the second warp yarn 42 to pass through. A partition 604 for hanging on the tensioned first warp yarn 41 and second warp yarn 42 is provided on the lower through hole 601. A contact surface 603 for contact cooperation with the stop sensor 80 is provided at the top of the upper through hole 602. When the first warp yarn 41 or the second warp yarn 42 breaks or is overly relaxed, the stop piece 60 descends, the stop sensor 80 contacts the contact surface 603, and a signal is transmitted to the host to stop the operation of the loom.
[0034] As a preferred embodiment of the present utility model, the first stop piece 61 and the second stop piece 62 have different lengths to facilitate the distinction of the stop piece 60.
[0035] As a preferred embodiment of the present utility model, each yarn guiding portion 31 is penetrated by one of the first warp yarn 41 or the second warp yarn 42, so that each first warp yarn 41 or second warp yarn 42 can be controlled individually.
[0036] In the present utility model, the specific structures of the first warp guiding member 10 and the second warp guiding member 20 may be the same as those introduced in the background art patent. Specifically, the first warp guiding member 10 includes a heddle frame and first warp guiding holes provided on the heddle frame. The upper end of the heddle frame is connected to the second lifting mechanism, and the lower end of the heddle frame is connected to the second reset mechanism 11. As a preferred embodiment of the present utility model, the second warp guiding member 20 includes a left lifting heddle arm, a right lifting heddle arm, and an intermediate half heddle. The left lifting heddle arm and the right lifting heddle arm have the same structure and are independent of each other. The intermediate half heddle is movably connected to both the left lifting heddle arm and the right lifting heddle arm and can be driven by the left lifting heddle arm or the right lifting heddle arm to move up and down. The intermediate half heddle is provided with second warp guiding holes for the second warp yarn 42 to pass through. The upper ends of the left lifting heddle arm and / or the right lifting heddle arm are connected to the third lifting mechanism, the lower ends of the left lifting heddle arm and / or the right lifting heddle arm are connected to the third reset mechanism 21, and the lower end of the intermediate half heddle is connected to the fourth reset mechanism. As a preferred embodiment of the present utility model, the intermediate half heddle includes a heddle head and two heddle feet connected to the heddle head. The second warp guiding holes are provided on the heddle head, and the lower ends of the heddle feet are connected to the fourth reset mechanism; the left lifting heddle arm and / or the right lifting heddle arm are provided with longitudinal through sections for the heddle feet to pass through for longitudinal lifting, and an interval space for the longitudinal lifting of the intermediate half heddle and for the unit warp beam to pass through is provided between the left lifting heddle arm and the right lifting heddle arm.
[0037] The first lifting mechanism, the second lifting mechanism, and the third lifting mechanism of the present utility model are all jacquard heads 90. The corresponding driving mechanisms in the existing jacquard heads 90 are used to respectively control the lifting of the heddle frame, the left lifting heddle arm, the right lifting heddle arm, and the yarn guiding part 31. The first reset mechanism 32, the second reset mechanism 11, the third reset mechanism 21, and the fourth reset mechanism of the present utility model are all springs. The downward reset of the left lifting heddle arm, the right lifting heddle arm, the intermediate half heddle, and the yarn guiding part 31 is controlled by multiple springs respectively. When the present utility model is in use, the first warp yarn 41 can be threaded through the yarn guiding part 31 and then into the first warp guiding member 10, and the second warp yarn 42 can be threaded through the yarn guiding part 31 and then into the intermediate half heddle. The horizontal positions of the first warp yarn 41 and the second warp yarn 42 can be controlled more flexibly through the yarn guiding part 31, so that the first warp yarn 41 and the second warp yarn 42 are in a better knitting position, improving the stability of knitting.
[0038] The protection scope of the present utility model is not limited to this embodiment. Any similar transformation made by anyone is regarded as not departing from the protection scope of the present utility model.
