Description

Shedding mechanism and loom

[0001] This application claims priority to Chinese patent applications filed on December 7, 2023, with application numbers 202323349272.6 and 202311682832.1, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of textile weaving equipment, and in particular to an opening mechanism and a loom. Background Art

[0003] A loom usually includes a warp let-off mechanism, an opening mechanism, a weft insertion mechanism, a beating-up mechanism and a take-up mechanism. The opening mechanism is used to drive the palm frame to reciprocate up and down, so that the warp yarn passing through the palm frame can move up and down with the palm frame and form different cloth fells, to ensure that the weft yarn sprayed by the weft insertion mechanism can pass through the cloth fell smoothly, and the beating-up mechanism will beat the weft yarn passing through the cloth fell to the warp yarn surface to form a fabric.

[0004] In the related art, the main power source of the opening mechanism is the main shaft, or multiple independent rotary servo motors are used to drive the movement of multiple palm frames. Whether the main shaft or the rotary servo motor is used as the power source, it is necessary to use a complex mechanical transmission mechanism such as belt transmission-reversing gear set-conjugate cam set-connecting rod to convert the rotary motion into linear motion. There are many conversion links and the conversion structure is complex. The adjustment of the up and down running stroke and state of the heald frame is very troublesome and requires mechanical adjustment. The running stroke and state of the palm frame cannot be directly and freely adjusted. Technical issues

[0005] The main purpose of this application is to propose an opening mechanism, which aims to provide an opening mechanism that can directly and freely adjust the running stroke and state of the palm frame. Technical Solutions

[0006] To achieve the above-mentioned purpose, the present application proposes an opening mechanism, comprising:

[0007] A brown frame array, the brown frame array comprising a plurality of brown frames distributed in an array along a first direction;

[0008] a bracket, the bracket being used to connect to a frame of a loom;

[0009] A linear drive module includes two linear drive units, each of which includes multiple direct drive units. The direct drive unit includes a stator module and a mover module. The stator module is connected to the bracket, and the mover module slides with the stator module. Each of the palm frames is connected to a mover module of the direct drive unit so that each mover module drives the corresponding palm frame to move back and forth up and down.

[0010] In one embodiment of the present application, in the same linear drive unit, the two direct drive units constitute a group of direct drive module units, and the direct drive module units are provided in multiple groups, and the multiple groups of direct drive module units are distributed in an array along the first direction.

[0011] In one embodiment of the present application, the two linear drive units of the linear drive module are staggered in the first direction.

[0012] In one embodiment of the present application, in the same group of the direct drive module units, the two stator modules are staggered in the first direction and in a second direction that is set at an angle to the first direction;

[0013] The length of one mover module extending from its corresponding stator module is greater than the length of the other mover module extending from its corresponding stator module, so that the ends of the two mover modules extending from their corresponding stator modules are flush with each other;

[0014] Alternatively, the lengths of the two mover modules extending from the corresponding stator modules are equal, so that the ends of the two mover modules extending from the corresponding stator modules are staggered in the second direction.

[0015] In one embodiment of the present application, in the same group of the direct-drive module units, the two stator modules are staggered in the first direction and the up-down direction, and the lengths of the two mover modules extending from the corresponding stator modules are equal, so that the ends of the two mover modules extending from the corresponding stator modules are flush.

[0016] In one embodiment of the present application, in the same group of the direct-drive module units, the two stator modules are arranged side by side in a second direction set at an angle to the first direction, wherein an end of one of the mover modules extending out of the corresponding stator module is provided with an extension portion, and the extension portion is spaced apart from the other mover module in the first direction so that the end of the extension portion is flush with the end of the other mover module extending out of the corresponding stator module.

[0017] In one embodiment of the present application, the linear drive module is located above the brown frame array.

[0018] In one embodiment of the present application, there are at least two of the brackets and the linear drive modules, at least two of the brackets are symmetrically distributed on both sides of the brown frame array, at least two of the linear drive modules are symmetrically distributed on both sides of the brown frame array, and the stator module of each of the linear drive modules is connected to one of the brackets.

[0019] In one embodiment of the present application, the opening mechanism further includes a plurality of palm frame lifting members, and each of the palm frames is connected to a mover module via a palm frame lifting member.

[0020] In one embodiment of the present application, a sink groove is provided on one side of the mover module, and an end of the palm frame lifting member away from the palm frame is provided in the sink groove.

[0021] In one embodiment of the present application, the bracket is provided with a through hole, and the palm frame pulling member is passed through the through hole.

[0022] The present application also proposes a loom, comprising a frame and the opening mechanism as described above, wherein a bracket of the opening mechanism is connected to the frame. Beneficial effects

[0023] In the opening mechanism proposed in the present application, each palm frame is directly connected to a movable module of the linear drive module, so that the linear drive module is used as the main power source for the palm frame to move back and forth. There is no complex mechanical transmission mechanism such as the intermediate belt transmission-reversing gear group-conjugate cam group-connecting rod, etc. The operating stroke and status of multiple palm frames can be freely adjusted by controlling the operating stroke and status of multiple direct drive units.

[0024] In addition, the intermediate mechanical transmission mechanism is eliminated, avoiding the transmission conversion process of converting rotational motion into linear motion, which can make the transmission more efficient, the response more direct, and the vibration and noise lower, which is more conducive to high-speed operation.

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0052] The present application proposes an opening mechanism 100 , which aims to provide an opening mechanism 100 that can directly and freely adjust the operating stroke and state of the palm frame.

[0053] The specific structure of the opening mechanism 100 of the present application will be described below:

[0054] Referring to Figures 1 to 20, in one embodiment of the opening mechanism 100 of the present application, the opening mechanism 100 includes a palm frame array 10, a bracket 20 and a linear drive module 30; the palm frame array 10 includes a plurality of palm frames distributed in an array along a first direction a; the bracket 20 is used to connect the frame of the loom; the linear drive module 30 includes two linear drive units 31, the linear drive unit 31 includes a plurality of direct drive units 311, the direct drive unit 311 includes a stator module 3111 and a mover module 3112, the stator module 3111 is connected to the bracket 20, the mover module 3112 is slidably matched with the stator module 3111, each palm frame is connected to the mover module 3112 of the direct drive unit 311, so that each mover module 3112 drives the corresponding palm frame to reciprocate up and down.

[0055] It can be understood that in the opening mechanism 100 proposed in the present application, by directly connecting each brown frame to a movable submodule 3112 of the linear drive module 30, the linear drive module 30 is used as the main power source for the brown frame to move back and forth, and there is no complex mechanical transmission mechanism such as the intermediate belt transmission-reversing gear group-conjugate cam group-connecting rod, etc. The operating stroke and state of multiple brown frames can be freely adjusted by controlling the operating stroke and state of multiple direct drive units 311.

[0056] In addition, the intermediate mechanical transmission mechanism is eliminated, avoiding the transmission conversion process of converting rotational motion into linear motion, which can make the transmission more efficient, the response more direct, and the vibration and noise lower, which is more conducive to high-speed operation.

[0057] In this embodiment, the linear drive module 30 can be controlled by an electric drive signal to directly control the corresponding mover module 3112 of the electric drive unit to perform up and down reciprocating motion, thereby driving the corresponding palm frame to perform up and down reciprocating motion.

[0058] It should be noted that when the opening mechanism 100 proposed in this application is applied to a loom, the bracket 20 can be connected to the loom frame, so that the linear drive module 30 is fixedly mounted on the loom frame via the bracket 20, thereby ensuring the installation reliability of the linear drive module 30. Furthermore, the palm frame array 10 can be mounted on the palm frame frame, and the palm frame frame can also be connected to the loom frame to ensure the installation reliability of the palm frame array 10.

[0059] In actual application, the linear drive module 30 can be set above the brown frame array 10, or below or to the side of the brown frame array 10, as long as it can drive the corresponding brown frame to move up and down through the mover module 3112.

[0060] In some embodiments, when the linear drive module 30 is disposed above the brown frame array 10 , the linear drive module 30 can be disposed near one side of the brown frame array 10 or in the middle of the brown frame array 10 .

[0061] In actual application, one or at least two linear drive modules 30 may be provided, and the specific number may be determined according to actual usage conditions.

[0062] In some embodiments, when at least two linear drive modules 30 are provided, each palm frame can be driven by at least two mover modules 3112 , so that the corresponding palm frame can be synchronously driven to reciprocate up and down by the at least two mover modules 3112 .

[0063] In some embodiments, the stator module 3111 may have a certain number of winding coils integrated therein; the mover module 3112 may have a specific array of permanent magnets integrated on both sides of the mover plate.

[0064] Referring to Figures 4, 9, 14, and 19, in some embodiments of the opening mechanism 100 of the present application, in the same linear drive unit 31, two direct drive units 311 constitute a group of direct drive module units 31a, and the direct drive module units 31a are provided in multiple groups, and the multiple groups of direct drive module units 31a are distributed in an array along the first direction a.

[0065] In this way, by distributing multiple groups of direct-drive module units 31a in an array in the first direction a, multiple direct-drive units 311 composed of multiple groups of direct-drive module units 31a can be distributed in an array in the first direction a, so that multiple actuator modules 3112 are distributed in an array along the first direction a to adapt to the arrangement of multiple brown frames and better utilize limited space.

[0066] 4 , 9 , 14 , and 19 , in some embodiments of the opening mechanism 100 of the present application, the two linear drive units 31 of the linear drive module 30 are staggered in the first direction a.

[0067] In this configuration, the two linear drive units 31 of the linear drive module 30 are staggered in the first direction a so that the two linear drive units 31 are arranged in a staggered manner, thereby making better use of limited space.

[0068] In some embodiments, referring to Figures 1 to 5, in the first embodiment, in the same group of direct-drive module units 31a, the two stator modules 3111 are staggered in a first direction a and a second direction b set at an angle to the first direction a; the length of one mover module 3112 extending from its corresponding stator module 3111 is greater than the length of the other mover module 3112 extending from its corresponding stator module 3111, so that the ends of the two mover modules 3112 extending from their corresponding stator modules 3111 are flush.

[0069] Because the spacing between the multiple brown frames of the brown frame array 10 is relatively small and the arrangement is relatively compact, in order to ensure a more compact arrangement of the multiple direct-drive units 311 of the linear drive module 30, the two stator modules 3111 of the same group of direct-drive module units 31a are staggered in the first direction a and the second direction b, and the length of one mover module 3112 extending from its corresponding stator module 3111 is greater than the length of the other mover module 3112 extending from its corresponding stator module 3111. This ensures that the ends of the two mover modules 3112 extending from their corresponding stator modules 3111 are aligned, ensuring that the lifting points of each brown frame are in the same position, and allowing the linear drive module 30 to adopt a "single-sided staggered brown frame single-point lifting" arrangement. This solves the problem of the feasibility of connecting the mover modules 3112 of the direct-drive unit 311 to the brown frames in a one-to-one correspondence within the limited space constraints due to the small spacing between the brown frame loads.

[0070] In some embodiments, the two stator modules 3111 of the same group of direct-drive module units 31a are the same size, are staggered in spatial layout position by the width distance of one stator module 3111 in the second direction b, and are staggered by the thickness distance of one stator module 3111 in the first direction a. In addition, the two mover modules 3112 of the same group of direct-drive module units 31a extend out of their corresponding stator modules 3111 by different lengths, and the length of one mover module 3112 extending out of its corresponding stator module 3111 is longer than the length of the other mover module 3112 extending out of its corresponding stator module 3111 by the width distance of one stator module 3111.

[0071] In some embodiments, when two linear drive modules 30 are provided and the two linear drive modules 30 are respectively arranged on both sides of the brown frame array 10, the linear drive modules 30 can be arranged in a "single-sided staggered double-sided opposite brown frame single-point pulling" manner.

[0072] It should be noted that the term "single-sided" refers to the brown frame array 10. In the second direction b, the left and right sides of the brown frame are the two single sides of the brown frame array 10, respectively. The two linear drive units 31 of the linear drive module 30 on one side are staggered in the first direction a, which is called "single-sided staggering." Bilateral opposition refers to the fact that the mover modules 3112 of the two linear drive modules 30 on both sides of the brown frame array 10 are connected oppositely on the same brown frame, and the same brown frame is connected to the two mover modules 3112 of the linear drive modules 30 on the left and right sides. Single-point lifting means that the lifting points on the same side of the brown frame are the same, that is, all the lifting points are connected on a horizontal line.

[0073] It should be noted that the second direction b is a direction extending along the length direction of the brown frame.

[0074] Referring to Figures 6 to 10, in the second embodiment, in the same group of direct-drive module units 31a, the two stator modules 3111 are staggered in a first direction a and a second direction b that is set at an angle to the first direction a; the lengths of the two mover modules 3112 extending from their corresponding stator modules 3111 are equal, so that the ends of the two mover modules 3112 extending from their corresponding stator modules 3111 are staggered in the second direction b.

[0075] To ensure a more compact arrangement of the multiple drive units of the linear drive module 30, the two stator modules 3111 of the same direct drive module unit 31a are staggered in the first direction a and the second direction b, and the lengths of the two mover modules 3112 extending from their corresponding stator modules 3111 are equal. This allows the ends of the two mover modules 3112 extending from their corresponding stator modules 3111 to be staggered in the second direction b. This allows the linear drive module 30 to be arranged using a "single-sided staggered palm frame with two-point pull" arrangement. This also solves the practical problem of achieving a one-to-one connection between the mover modules 3112 of the direct drive unit 311 and the palm frame within limited space constraints due to the small load spacing between the palm frames.

[0076] In some embodiments, the two stator modules 3111 of the same group of direct-drive module units 31a are the same size, and are staggered in spatial layout position by the width distance of a stator module 3111 in the second direction b, and are staggered by the thickness distance of a stator module 3111 in the first direction a. In addition, the two mover modules 3112 of the same group of direct-drive module units 31a extend out of their corresponding stator modules 3111 by the same length, so that the ends of the two mover modules 3112 extending out of their corresponding stator modules 3111 are staggered in the second direction b.

[0077] In some embodiments, when two linear drive modules 30 are provided and the two linear drive modules 30 are respectively arranged on both sides of the brown frame array 10, the linear drive modules 30 can be arranged in a "single-sided staggered double-sided opposing brown frame double-point pulling" manner.

[0078] It should be noted that double-point lifting means that the lifting points on the same side of the brown frame are different, that is, all the lifting points can be connected to form two parallel horizontal lines.

[0079] 11 to 15 , in the third embodiment, in the same group of direct-drive module units 31a, the two stator modules 3111 are staggered in the first direction a and the up-down direction c, and the two mover modules 3112 extend out of their corresponding stator modules 3111 by the same length, so that the ends of the two mover modules 3112 extending out of their corresponding stator modules 3111 are flush.

[0080] To ensure a more compact arrangement of the multiple drive units of the linear drive module 30, the two stator modules 3111 of the same direct drive module unit 31a are staggered in the first direction a and the vertical direction c, and the two mover modules 3112 extend equal distances from their corresponding stator modules 3111. This ensures that the ends of the two mover modules 3112 extending from their corresponding stator modules 3111 are flush, ensuring that the lifting points of each palm frame are aligned. This allows the linear drive module 30 to be arranged in a "vertically staggered palm frame single-point lifting" arrangement. This also solves the problem of the feasibility of connecting the mover modules 3112 of the direct drive unit 311 to the palm frame in a one-to-one correspondence within the limited space constraints due to the small load spacing between the palm frames.

[0081] In some embodiments, the two stator modules 3111 of the same group of direct-drive module units 31a are the same size, and are staggered by a height distance of one stator module 3111 in the up-down direction c in the spatial layout position, and are staggered by a thickness distance of one stator module 3111 in the first direction a. In addition, the two mover modules 3112 of the same group of direct-drive module units 31a extend out of their corresponding stator modules 3111 by the same length, so that the ends of the two mover modules 3112 extending out of their corresponding stator modules 3111 are flush.

[0082] In some embodiments, when two linear drive modules 30 are provided and the two linear drive modules 30 are respectively arranged on both sides of the brown frame array 10, the linear drive modules 30 can be arranged in a "vertically staggered double-sided brown frame single-point pulling" manner.

[0083] It should be noted that the single side refers to the brown frame array 10. In the second direction b, the left and right sides of the brown frame are the two single sides of the brown frame array 10 respectively. The two stator modules 3111 of the single-sided linear drive module 30 are staggered in the up and down direction c, that is, "staggered up and down".

[0084] Referring to Figures 16 to 20, in the fourth embodiment, in the same group of direct-drive module units 31a, two stator modules 3111 are arranged side by side in a second direction b that is set at an angle to the first direction a, and an extension portion 3112a is provided at the end of one of the mover modules 3112 extending out of its corresponding stator module 3111, and the extension portion 3112a is spaced apart from the other mover module 3112 in the first direction a so that the end of the extension portion 3112a is flush with the end of the other mover module 3112 extending out of its corresponding stator module 3111.

[0085] To ensure a more compact arrangement of the multiple drive units of the linear drive module 30, the two stator modules 3111 of the same group of direct drive module units 31a are arranged side by side in the second direction b, and an extension portion 3112a is provided at the end of one mover module 3112 extending from its corresponding stator module 3111. This extension portion 3112a is spaced apart from the other mover module 3112 in the first direction a, so that the end of the extension portion 3112a is flush with the end of the other mover module 3112 extending from its corresponding stator module 3111. This ensures that the lifting points of each palm frame are aligned, allowing the linear drive module 30 to be arranged in a "left-right staggered palm frame single-point lifting" arrangement. This also solves the problem of the feasibility of connecting the mover modules 3112 of the direct drive unit 311 to the palm frame in a one-to-one correspondence within the limited space constraints due to the small load spacing between the palm frames.

[0086] In some embodiments, when two linear drive modules 30 are provided and the two linear drive modules 30 are respectively arranged on both sides of the brown frame array 10, the linear drive modules 30 can be arranged in a "single-point lifting of all staggered double-sided opposing brown frames" manner.

[0087] It should be noted that the single side refers to the brown frame array 10. In the second direction b, the left and right sides of the brown frame are the two single sides of the brown frame array 10 respectively. The two stator modules 3111 of the single-sided linear drive module 30 are side by side in the second direction b, which is "left-right staggered".

[0088] Optionally, referring to Figures 1, 2, 6, 7, 11, 12, 16, and 17, in one embodiment of the opening mechanism 100 of the present application, the linear drive module 30 is located above the brown frame array 10.

[0089] In this configuration, by arranging the linear drive module 30 above the brown frame array 10 , the space above the brown frame can be fully utilized, making the spatial layout of the opening mechanism 100 more compact.

[0090] In actual application, the bracket 20 can also be located above the brown frame array 10 or to the side of the brown frame array 10. Of course, in some embodiments, in order to make the spatial layout of the opening mechanism 100 more compact, the bracket 20 can be placed above the brown frame array 10 so that the linear drive module 30 is supported on the bracket 20.

[0091] Optionally, with reference to Figures 1 to 3, 6 to 8, 11 to 13, and 16 to 18, in one embodiment of the opening mechanism 100 of the present application, there are at least two brackets 20 and at least two linear drive modules 30, at least two brackets 20 are symmetrically distributed on both sides of the brown frame array 10, at least two linear drive modules 30 are symmetrically distributed on both sides of the brown frame array 10, and the stator module 3111 of each linear drive module 30 is connected to one bracket 20.

[0092] By providing at least two linear drive modules 30 in this manner, the mover modules 3112 of the at least two linear drive modules 30 can be connected oppositely to the same brown frame. This allows the same brown frame to be connected to the mover modules 3112 of at least two linear drive modules 30, allowing each brown frame to be synchronously driven by at least two mover modules 3112, resulting in more efficient transmission. Furthermore, by providing at least two brackets 20, the stator module 3111 of each linear drive module 30 can be connected to a single bracket 20, ensuring reliable installation of the at least two linear drive modules 30.

[0093] Optionally, at least two brackets 20 may be an integrated bracket structure that spans both sides of the brown frame array 10 , so that the stator modules 311 of at least two linear drive modules 30 are connected to the integrated bracket structure.

[0094] Optionally, referring to Figures 5, 10, 15, and 20, in one embodiment of the opening mechanism 100 of the present application, the opening mechanism 100 further includes a plurality of palm frame lifting members 40, and each palm frame is connected to a mover module 3112 via a palm frame lifting member 40.

[0095] With such a configuration, by using the palm frame lifting member 40 to connect the palm frame and the mover module 3112 , the connection between the palm frame and the mover module 3112 can be more easily achieved.

[0096] In actual application, the palm frame lifting member 40 can be a lifting structure in the shape of a rod, sheet, plate, etc., as long as it can achieve the connection between the palm frame and the mover module 3112, and no specific limitation is made here.

[0097] Optionally, referring to Figures 5, 10, 15, and 20, in one embodiment of the opening mechanism 100 of the present application, a sink groove 3112b is provided on one side of the movable module 3112, and the end of the palm frame lifting member 40 away from the palm frame is provided in the sink groove 3112b.

[0098] In this way, by setting the end of the palm frame lifting member 40 away from the palm frame in the sink groove 3112b of the movable module 3112, the palm frame lifting member 40 does not occupy additional space, so that adjacent movable modules 3112 can be arranged more compactly, and the feasibility problem of the movable module 3112 of the direct drive unit 311 being connected one-to-one with the palm frame in a limited space constraint due to the small load spacing of the palm frame is better solved.
