Description

Technical Field

[0001] The present invention belongs to the technical field of textiles, and particularly relates to an automatic filament joining method. Background Art

[0002] In the production of polyester FDY, DTY, etc., the produced silk ingots are temporarily placed on a silk cart. The silk cart has two sides, and generally 15 - 48 are stored on each side. Then, pre - inspection processing and dyeing tests need to be carried out on the silk ingots on the silk cart. The current method is to first strip a certain length of the silk bundle of each silk ingot, then perform knitting of a certain length, and finally carry out a dyeing test. After stripping, the operator winds the silk thread heads of all the silk ingots on the entire silk cart into a silk ball, places the silk ball in the paper tube of any one silk ingot, and then pushes the silk cart to the side of the knitting machine. When knitting, the operator needs to take out the silk ball from the paper tube of the silk ingot on the silk cart, then sequentially find the silk threads of each silk ingot, cut them from the silk ball and connect them to the tail silk of the sock knitting machine. Wait for the previous silk ingot to finish knitting at a fixed length and then cut, and then connect the silk head of the next silk ingot. In this way, continuous sock bands are knitted one by one. Since stripping, taking silk, cutting silk, separating silk, and joining silk are all completed manually, the labor intensity is high and a large number of workers are required.

[0003] Chinese patent document CN114890237A discloses an intelligent automatic silk arranging and joining device. Its wire separating module utilizes the pulling force generated by the wire sucking device in the wire stripping process to make the wire bundles neatly arranged in rows and columns during operation, and then inserts a wire separating and clamping device. When the wire stripping ends, the wire bundles are neatly fixed on the clamping device at a certain interval, thereby realizing the separation of the wire path. Since the spatial position of the wire bundle is fixed and known, the manipulator can automatically complete taking silk and joining silk under the control of the program. However, in the above - mentioned scheme, the wire separating process needs to rely on the wire stripping process, its joining device must be together with the wire stripping, and the wire needs to be clamped in advance before being clamped by the wire clamp. Due to the reason of the wire unwinding angle during wire stripping, there is a certain distance requirement between the wire sucking gun and the silk ingot. Longer wires will generate too much waste wire, and at the same time, the number is large and the unwinding time is relatively long, resulting in more waste and poor economic benefits. Considering the wire unwinding angle and ensuring that dozens of ingots on the whole vehicle are straightened and pushed and wound, a sufficient distance is required to ensure the effect. The longer the distance, the greater the stroke and size of other mechanisms will be, the floor area will be large, and the manufacturing cost will be high. Summary of the Invention

Compared with all the wire spindles being connected to one wire ball and unwound at the same time, the method of the embodiment of the present invention reduces the generation of waste wire; generally, the wire ball is pulled in front of the axis of the wire spindle at the center position of each group, and the unwinding angle of each wire spindle is the angle between the straight line where the wire between the wire spindle and the wire ball is located and the axis of the wire spindle. After grouping, the unwinding angle of the edge wire spindles of each group is smaller than the unwinding angle when all the wire spindles are connected to one wire ball, and it is easier to unwind; if the wire spindles maintain the same unwinding angle, after grouping, compared with when all the wire spindles are connected to one wire ball, the equipment used for wire joining should be closer to the wire machine, so that the flying wire head after the broken wire is shorter after the socks are knitted, and the equipment mechanism for wire joining is small in size, occupies less space, and has low manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Figure 1 It is a flow chart of the automatic wire connection method according to an embodiment of the present invention;

[0038] Figure 2(a) is a schematic diagram of the partitions when the ingots are arranged in an S shape in an embodiment of the present invention; Figure 2 (b) is a schematic diagram of the partitions when the ingots are arranged in a Z shape in an embodiment of the present invention; Figure 2 (c) is a schematic diagram of the partitioning when the spindles are arranged in a double Z shape in an embodiment of the present invention. DETAILED DESCRIPTION

[0039] The technical solution of the present invention is described in detail below with reference to the accompanying drawings.

[0040] The embodiment of the present invention provides an automatic wire connection method, such as Figure 1 As shown, the following steps are included:

[0041] Step 10) Divide the side of the wire cart full of wire ingots into N areas, and the N areas are arranged in an array. Wind the wire ends of all the wire ingots in the same area into a wire ball after being stripped, and put the wire ball into the paper tube of any wire ingot in the area. N is an integer greater than 1. Preferably, the number of wire ingots in each area is equal.

[0042] Step 20) Connect the silk threads of all the spindles on the silk machine to the sock shaking machine in sequence according to the spindle numbers.

[0043] The automatic wire joining method of the embodiment of the present invention divides the wire spindles of the wire car into at least two groups, and the wire ends of each group of wire spindles after stripping are wound into a wire ball. When joining the wires, the wire ball where the wire to be joined is located is taken out, and all the wire spindles of the wire ball are unwound at the same time, while other wire balls are not unwound. Compared with all the wire spindles connected to one wire ball and unwound at the same time, the method of the embodiment of the present invention reduces the generation of waste wire. Generally, the wire ball is pulled in front of the axis of the wire spindle at the center position of each group. The unwinding angle of each wire spindle is the angle between the straight line where the wire between the wire spindle and the wire ball is located and the axis of the wire spindle. After grouping, the unwinding angle of the edge wire spindles of each group is smaller than the unwinding angle when all the wire spindles are connected to one wire ball, and it is easier to unwind. If the wire spindles maintain the same unwinding angle, after grouping, compared with when all the wire spindles are connected to one wire ball, the automatic wire joining device should be closer to the wire car, so that the flying wire head after the broken wire is shorter after the socks are knitted, and the automatic wire joining device has a small mechanism size, occupies less space, and has a low manufacturing cost.

[0044] like Figure 2 As shown, the silk ingots are generally placed on the silk car in the following three forms: S-shaped arrangement ( Figure 2 (a)), Z-shaped arrangement ( Figure 2 (b)) and double Z-type arrangement ( Figure 2(as shown in (c)). Preferably, N = 2. Regardless of the form adopted, one side of the silk ingot is divided into two left and right regions. Taking 24 silk ingots on one side of a silk-reeling machine as an example, 12 silk ingots on the left are grouped into one set, and the silk thread heads after silk stripping are wound into a silk ball. 12 silk ingots on the right are grouped into one set, and the silk thread heads after silk stripping are wound into a silk ball. Or, preferably, N = 3. Regardless of the form adopted, one side of the silk ingot is divided into three regions from left to right. Taking 24 silk ingots on one side of a silk-reeling machine as an example, 8 silk ingots on the left are grouped into one set, and the silk thread heads after silk stripping are wound into a silk ball. 8 silk ingots in the middle are grouped into one set, and the silk thread heads after silk stripping are wound into a silk ball. 8 silk ingots on the right are grouped into one set, and the silk thread heads after silk stripping are wound into a silk ball. Or, preferably, N = 4. One side of the silk ingot is divided into four regions: upper, lower, left, and right. Taking 24 silk ingots on one side of a silk-reeling machine as an example, 6 silk ingots in the upper left are grouped into one set, and the silk thread heads after silk stripping are wound into a silk ball. 6 silk ingots in the upper right are grouped into one set, and the silk thread heads after silk stripping are wound into a silk ball. 6 silk ingots in the lower left are grouped into one set, and the silk thread heads after silk stripping are wound into a silk ball. 6 silk ingots in the lower right are grouped into one set, and the silk thread heads after silk stripping are wound into a silk ball.

[0045] As a preferred example, step 20) specifically includes:

[0046] Step 201): According to the silk ingot serial numbers, take out P silk balls. Among them, P is an integer greater than 0 and less than or equal to N. The silk ingot serial numbers in the P silk balls are consecutive. Cut off the silk balls from the silk bundle and keep the silk thread heads of the P silk bundles.

[0047] Step 202): Lift the silk thread of the first silk ingot in the P silk bundles and connect it to the tail silk of the hosiery machine.

[0048] Step 203): After the hosiery machine stores silk for a preset time period, cut off the silk thread connected between the silk ingot and the hosiery machine. The silk thread extended from the hosiery machine serves as the tail silk of the hosiery machine. Lift the silk thread of the next silk ingot and connect it to the tail silk of the hosiery machine.

[0049] Step 204): Execute step 203) until all the silk threads of the P silk bundles are connected to the hosiery machine in sequence according to the silk ingot serial numbers.

[0050] Step 205): Take out the adjacent P silk balls where the next silk ingot is located, cut off the silk balls from the silk bundle, and keep the silk thread heads of the P silk bundles. Execute step 202) until all the silk threads of all the silk balls on the silk-reeling machine are connected to the hosiery machine in sequence according to the silk ingot serial numbers.

[0051] Preferably, P = 1. Take one silk ball at a time, keep the silk thread head of one silk bundle, and connect the silk thread of this silk bundle to the hosiery machine in sequence according to the silk ingot serial numbers.

[0052] If the silk ingots are arranged in a double-Z shape, a scheme of taking one silk ball at a time can be adopted. Taking the division into two left and right regions as an example, Figure 2(c). Specifically:

[0053] Take out the silk ball on the left, cut the silk ball from the silk bundle, and keep the thread end of one silk bundle. Lift the thread of spool No. 1 and connect it to the tail thread of the hosiery machine. After the preset time period for the hosiery machine to store silk, cut the thread between spool No. 1 and the hosiery machine, and the thread extended from the hosiery machine serves as the tail thread of the hosiery machine. Lift the thread of spool No. 2 and connect it to the tail thread of the hosiery machine. After the preset time period for the hosiery machine to store silk, cut the thread between spool No. 2 and the hosiery machine. Then lift the thread of spool No. 3 and connect it to the tail thread of the hosiery machine. And so on until the thread between spool No. 12 and the hosiery machine is cut. Take out the silk ball on the right, and then connect spool No. 13, spool No. 14, ···, spool No. 24 to the hosiery machine in turn until the thread between spool No. 24 and the hosiery machine is cut, thus completing the hosiery of all spools on one side of the silk car.

[0054] Or, preferably, P = 2. Take two silk balls at a time, keep the thread ends of two silk bundles, and connect the threads of these silk bundles to the hosiery machine in turn according to the spool serial number.

[0055] If the spools are arranged in an S shape or a Z shape, the scheme of taking two silk balls at a time can be adopted. Taking the example that the spools are arranged in an S shape and divided into left and right areas, as Figure 2 (a) shown. Specifically:

[0056] Take out two silk balls on the left and right at the same time, cut the two silk balls from the two silk bundles respectively, and keep the thread ends of the two silk bundles. Lift the thread of spool No. 1 and connect it to the tail thread of the hosiery machine. After the preset time period for the hosiery machine to store silk, cut the thread between spool No. 1 and the hosiery machine, and the thread extended from the hosiery machine serves as the tail thread of the hosiery machine. Lift the thread of spool No. 2 and connect it to the tail thread of the hosiery machine. After the preset time period for the hosiery machine to store silk, cut the thread between spool No. 2 and the hosiery machine. Then lift the thread of spool No. 3 and connect it to the tail thread of the hosiery machine. After the preset time period for the hosiery machine to store silk, cut the thread between spool No. 3 and the hosiery machine. Spool No. 4 is in the right area. Since the head has been left on the right silk bundle, the thread of spool No. 4 can be directly lifted and connected to the tail thread of the hosiery machine. And so on, connect spool No. 5, spool No. 6, ···, spool No. 24 to the hosiery machine in turn until the thread between spool No. 24 and the hosiery machine is cut, thus completing the hosiery of all spools on one side of the silk car.

[0057] The method of this embodiment takes two or more silk balls at a time and leaves the heads of two or more silk bundles at the same time, which is convenient for lifting the threads of the spools in sequence according to the spool serial number and connecting them to the hosiery machine, improving the thread connection speed and efficiency.

[0058] Specifically, in step 201), the silk mass is taken out, cut off from the silk bundle, and the thread end of the silk bundle is retained, specifically including:

[0059] Reach into the silk bobbin paper tube to take out the silk mass, and draw the silk mass through the splicing work area and the silk suction work area in sequence and then reach the broken wire area. In the silk suction work area, all the threads of the silk bundle are sucked by generating negative pressure, and the silk mass is cut off from the silk bundle in the broken wire area, and the threads of the silk bundle continue to unwind under the action of negative pressure.

[0060] The method of this embodiment reaches into the silk bobbin paper tube to grab the silk mass and drives the silk mass to move, so as to draw the silk thread into the splicing work area and the silk suction work area. The reliability of taking silk is high, and the silk thread will not be damaged. The silk thread is sucked by negative pressure to retain the thread end, preparing for picking and splicing the silk.

[0061] Since the thread end of the silk bundle is retained by sucking with negative pressure after taking the silk, the silk bobbins of the same silk bundle continue to unwind. In order to save silk and reduce waste silk generation when taking two or more silk masses at the same time, as a preferred example, in step 201), after cutting off the P silk masses from the P silk bundles respectively, keep the threads of the first silk bundle continuing to unwind, and stop generating negative pressure acting on the remaining silk bundles, so that the threads of the remaining silk bundles stop unwinding.

[0062] In step 203), before picking up the thread of the next silk bobbin, if the thread of the next silk bobbin and the thread of the previous silk bobbin are in the same silk bundle, pick up the thread of the next silk bobbin. If the thread of the next silk bobbin is in another silk bundle, stop generating negative pressure acting on the silk bundle where the previous silk bobbin is located, so that all the threads of the silk bundle where the previous silk bobbin is located stop unwinding, and start generating negative pressure acting on the silk bundle where the next silk bobbin is located, so that all the threads of the silk bundle where the next silk bobbin is located start to unwind, and then pick up the thread of the next silk bobbin.

[0063] The method of this embodiment stops the silk bobbins of the remaining silk bundles from unwinding when picking and splicing the silk of one silk bobbin, except for the silk bobbins of the silk bundle where it is located, so that no waste silk is generated in the remaining silk bundles and the silk is saved.

[0064] Specifically, picking up the thread of the silk bobbin specifically includes:

[0065] In the splicing work area, the first silk picking hook and the second silk picking hook are arranged closely in sequence along the traction direction of the silk thread to be spliced. The silk thread is blocked by the two silk picking hooks during unwinding and slides down along the hook arms of the two silk picking hooks and enters the hook cavity of the silk picking hook from the opening of the silk picking hook. The two silk picking hooks are separated, and the silk thread is clamped at the first silk picking hook and the second silk picking hook, so that the silk thread stops unwinding. Cut the silk thread on the side of the second silk picking hook away from the first silk picking hook.

[0066] The method of this embodiment utilizes the negative pressure during wire taking to continuously unwind the wire. During the unwinding process, the wire is hooked by two combined wire picking hooks, and then the two wire picking hooks are separated. The wire is clamped at the first wire picking hook and the second wire picking hook, causing the wire to stop unwinding, saving the wire, reducing the generation of waste wire, and facilitating the cutting of the wire for wire connection preparation.

[0067] Preferably specifically, in step 203), before cutting the wire connecting the wire bobbin and the hosiery machine, the wire connected to the hosiery machine is clamped on both sides of the knotter.

[0068] Connecting the wire to the end wire of the hosiery machine specifically includes:

[0069] Move the knotter below the wire to be connected. Start the knotter to connect the wire to be connected and the end wire located between the first wire picking hook and the second wire picking hook. After the connection is completed, release the wire to be connected at the first wire picking hook and the second wire picking hook, and release the end wire on the side of the knotter close to the wire cart.

[0070] In the method of this embodiment, each time after the wire storage of the previous wire bobbin is completed, before cutting the wire of the previous wire bobbin, the wire connected to the hosiery machine is clamped on both sides of the knotter, and a section of the wire extending from the hosiery machine is reserved on the knotter, thus serving as the end wire of the hosiery machine.

[0071] As a preferred example, step 20) specifically includes:

[0072] Step 201): According to the wire bobbin number, take out adjacent P wire clusters. Where P is an integer greater than 0 and less than or equal to N. The wire bobbin numbers in the P wire clusters are consecutive. Cut the wire clusters from the wire bundle and keep the wire ends of the P wire bundles.

[0073] Step 202): Simultaneously lift the wires of the consecutive Q wire bobbins including the first wire bobbin in the P wire bundles, and connect the wire of the first wire bobbin to the end wire of the hosiery machine. Where Q is an integer greater than 1 and less than or equal to 8.

[0074] Step 203): After the hosiery machine stores wire for a preset time period, cut the wire connecting the wire bobbin and the hosiery machine. The wire extending from the hosiery machine serves as the end wire of the hosiery machine. Lift the wire of the next wire bobbin and connect it to the end wire of the hosiery machine.

[0075] Step 204): Execute step 203) until the wires of the Q wire bobbins are all connected to the hosiery machine in sequence according to the wire bobbin numbers.

[0076] Step 205): Simultaneously lift the wires of the consecutive Q wire bobbins including the next wire bobbin, and connect the wire of the next wire bobbin to the end wire of the hosiery machine. Execute step 203) until all the wires of the P wire bundles are connected to the hosiery machine in sequence according to the wire bobbin numbers.

[0077] Step 206) Take out the adjacent P silk clusters where the next silk bobbin is located, cut off the silk clusters from the silk bundle, and retain the thread ends of P silk bundles. Execute Step 202) until the threads of all silk clusters on the silk cart are connected to the hosiery machine in sequence according to the silk bobbin numbers.

[0078] Preferably, P = 1. Take one silk cluster at a time, retain the thread end of one silk bundle, and connect the thread of this silk bundle to the hosiery machine in sequence according to the silk bobbin numbers. Alternatively, preferably, P = 2. Take two silk clusters at a time, retain the thread ends of two silk bundles, and connect the threads of these silk bundles to the hosiery machine in sequence according to the silk bobbin numbers.

[0079] Preferably, Q = 2. The threads of two consecutive silk bobbins in the same row can be lifted at one time, and then the threads are connected to the hosiery machine in sequence. Alternatively, preferably, Q = 3. The threads of three consecutive silk bobbins in the same row can be lifted at one time, and then the threads are connected to the hosiery machine in sequence. This is applicable to the case where there are six silk bobbins in one row of the silk cart. Preferably, Q = 4. The threads of four consecutive silk bobbins in the same row can be lifted at one time, and then the threads are connected to the hosiery machine in sequence. This is applicable to the case where there are eight silk bobbins in one row of the silk cart.

[0080] Taking the case where the silk bobbins are arranged in a Z shape and divided into left and right regions, and the threads of three consecutive silk bobbins in the same row can be lifted at one time as an example, as Figure 2 (b) shown. Specifically:

[0081] Take out the two silk clusters on the left and right at the same time, cut off the two silk clusters from the two silk bundles respectively, and retain the thread ends of the two silk bundles. Lift the threads of the 1st, 2nd, and 3rd silk bobbins, and connect the thread of the 1st silk bobbin to the tail thread of the hosiery machine. After the hosiery machine stores silk for a preset time period, cut off the thread between the 1st silk bobbin and the hosiery machine, and the thread extended from the hosiery machine is used as the tail thread of the hosiery machine. Lift the thread of the 2nd silk bobbin and connect it to the tail thread of the hosiery machine. After the hosiery machine stores silk for a preset time period, cut off the thread between the 2nd silk bobbin and the hosiery machine, then lift the thread of the 3rd silk bobbin and connect it to the tail thread of the hosiery machine. After the hosiery machine stores silk for a preset time period, cut off the thread between the 3rd silk bobbin and the hosiery machine. The 4th silk bobbin is in the right region. Since the head of the right silk bundle has been retained, the threads of the 4th, 5th, and 6th silk bobbins can be lifted at the same time, and the thread of the 4th silk bobbin is connected to the tail thread of the hosiery machine. In this way, connect the 5th, 6th, ···, 24th silk bobbins to the hosiery machine in sequence until the thread between the 24th silk bobbin and the hosiery machine is cut off, thus completing the hosiery of all silk bobbins on one side of the silk cart.

[0082] In this embodiment, two or more silk balls are taken at a time, and the heads of two or more filaments are left.
