Description

Technical Field

[0001] This invention belongs to the field of textile equipment technology, specifically relating to an automatic horizontally moving longitudinally separating jacquard pattern plate and its control method. Background Technology

[0002] like Figure 1 As shown, in the heddle threading stage of jacquard equipment, it is often necessary to separate and move the guide yarns passing through the heddle plate to one side for better heddle threading. This process requires external tools such as elastic ropes and S-hooks of different sizes, and also consumes a certain amount of physical strength. After threading one row of heddle yarns, they need to be moved to the other side to prevent affecting the threading of the next row. Even under conditions of sufficient preparation, after all the heddle yarns are threaded, the guide yarns may still become tangled, affecting the next process, i.e., reed threading. In some cases, the yarn may even break due to heddle yarn rebound or the yarn being threaded in the wrong order during straight-line movement. This seriously affects production efficiency. Furthermore, this operation is highly repetitive; increasing the degree of automation in the operation process can further improve production efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a control method for automatically moving a longitudinally separated jacquard pattern plate horizontally, thereby solving the problem of complex threading processes, improving automation, and simultaneously enhancing accuracy.

[0004] The technical solution provided by this invention is as follows:

[0005] An automatic horizontally moving longitudinally separating jacquard pattern plate device, comprising:

[0006] A pair of horizontally fixed conveyor belts, each driven by a stepper motor, with baffles provided at the front and rear ends of each conveyor belt;

[0007] A jacquard pattern is composed of several separate pattern strips, with each of the two ends of the separate pattern strips pressed onto a conveyor belt.

[0008] Several pairs of telescopic cylinders are fixedly installed on the side fixing frames on both sides of the conveyor belt, and the side fixing frames are provided with zero scale lines;

[0009] And a control device, wherein the control device is electrically connected to each of the stepper motors and each of the telescopic cylinders.

[0010] Based on the above technical solution, the separate eyelet strips can be moved individually by control as needed during threading, thereby improving the automation level of the operation.

[0011] Specifically, the file frame is vertically arranged with the conveying belt, and the left and right ends of the file frame are respectively provided with mounting grooves, and the end of the conveying belt extends into the mounting grooves and is fixedly installed in the mounting grooves through the mounting frame.

[0012] Based on the above technical scheme, the file frame can not only fixedly install the conveying belt, but also provide a fence for the separated eyelet strip.

[0013] Further, the middle part of each side fixing frame is provided with a wire slot for the air pipe of the air cylinder.

[0014] Based on the above technical scheme, the wire of the air pipe of the air cylinder is convenient.

[0015] Specifically, each separated eyelet strip is provided with a row of through holes penetrating up and down, for passing through the heald;

[0016] Specifically, the lower part of the longitudinally separated chain type movable jacquard eyelet is provided with a lower eyelet.

[0017] Further, the control device is provided with a touch operation screen.

[0018] Based on the above technical scheme, the convenience of operation is improved.

[0019] The application also provides a control method for automatically horizontally moving a longitudinally separated jacquard eyelet, which adopts the above automatic horizontal moving longitudinally separated jacquard eyelet device for operation, and specifically includes the following steps:

[0020] 1) Place each separated eyelet strip on the conveying belt, and align the rightmost separated eyelet strip with the zero scale line;

[0021] 2) Control each step motor to drive each conveying belt to drive each separated eyelet strip to move to the starting position as a whole;

[0022] 3) First, control the telescopic air cylinders on the left and right sides of the second separated eyelet strip on the right to clamp and fix the second separated eyelet strip on the right, and then control each step motor to drive each conveying belt to drive the first separated eyelet strip on the right to move twice to reset to the zero scale line, wherein the healding is performed after the first movement;

[0023] 4) Following the method in step 3), first control the telescopic cylinders on both sides of the 1st and nth right-side separable eye strips to clamp and fix the 1st and nth right-side separable eye strips. Then, control each stepper motor to drive each conveyor belt, causing the (n-1)th right-side separable eye strip to move twice to the back of the (n-2)th separable eye strip to reset each separable eye strip. After the first movement of each separable eye strip, the heddle is threaded. n is a natural number greater than 3. Finally, reset the nth separable eye strip through two movements.

[0024] Based on the above technical solution, a high degree of automation control can be achieved by automatically moving the longitudinally separated jacquard pattern plate horizontally, thereby solving the problem of complex threading process, improving automation level, and simultaneously enhancing accuracy.

[0025] Furthermore, for each separate heddle strip, the stepper motor is paused after the first movement to provide time for the threading operation.

[0026] If there is an error in the threading operation, the split eyelet strip can be manually restored to its starting position.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1) Threading the heddles is relatively smoother, and the efficiency of threading the heddles is further improved;

[0029] 2) Reduce human intervention, thread the heddles in sequence to reduce error rate and significantly improve threading quality;

[0030] 3) The entanglement between the threads will disappear, and the lifting of the heddle will be smoother.

[0031] 4) High degree of automation. Attached Figure Description

Each separate pattern plate strip 7 is provided with a row of through holes 2 penetrating up and down, for passing through the through wire 3. The lower part of the longitudinally separated chain type moving jacquard pattern plate is provided with a lower pattern plate 6.

[0040] Example 1

[0041] On the basis of the above embodiment, as shown in Figure 3 , the rack 11 is arranged vertically with the conveying belt 9, the left and right ends of the rack 11 are respectively provided with mounting grooves 12, and the end of the conveying belt 9 extends into the mounting groove 12 and is fixedly installed in the mounting groove 12 through the mounting frame.

[0042] In another embodiment, the control method of the automatic horizontal moving longitudinal separate jacquard pattern plate comprises the following steps:

[0043] 1) Place each separate pattern plate strip 7 on the conveying belt 9, and align the rightmost separate pattern plate strip 7 with the zero scale line, which is in the reset position;

[0044] 2) Control each stepping motor to drive each conveying belt 9 to drive each separate pattern plate strip 7 to move left as a whole to the starting position;

[0045] 3) First control the right side of the second separate eyelet strip 7 both sides of the telescopic cylinder 13 clamping, fixed right side of the second separate eyelet strip 7, then control each step motor drive each conveyor belt 9, drive the right side of the first separate eyelet strip 7 to move twice, to reset to zero scale line, wherein, after the first time, the move is performed through the eyelet.

[0046] 4) According to the way of step 3), respectively, first control the right side of the first and the n separate eyelet strip 7 both sides of the telescopic cylinder 13 clamping, fixed right side of the first and the n separate eyelet strip 7, then control each step motor drive each conveyor belt 9, drive the right side of the (n-1) separate eyelet strip 7 to move twice to the back of the (n-2) separate eyelet strip 7, to reset each separate eyelet strip 7, wherein, after the first time, the move is performed through the eyelet. N is 3, 4, 5…, until, finally, the n separate eyelet strip 7 is reset by moving twice.

[0047] For example, the following example operation can be conveniently performed by touch operation screen:

[0048] First, the width of the eyelet strip is known to be m, and the zero scale position is set, that is, the rightmost of the original first eyelet strip is the scale.

[0049] Through the touch operation screen, control the step motor to move all the eyelet strips 8 cm to the left as a whole, that is, at the scale-8 cm.

[0050] After the whole movement, start from the first eyelet strip, that is, at the scale-8 cm, move to the right in two steps, the first step moves 4 cm, and the second step moves 4 cm. Specifically, through the touch operation screen, control the cylinder clamping on both sides of the second eyelet strip, then control the step motor to move the first eyelet strip twice by 4 cm through the conveyor belt.

[0051] After the first eyelet strip moves to the right, start moving the second eyelet strip, that is, through the operation of the touch operation screen, control the step motor to move to the left to the scale-(8+m) cm. Then control the cooperation of the cylinder and the step motor to move the second eyelet strip twice by 4 cm, a total of 8 cm to the right.

Then control the cooperation of the cylinder and the step motor to move the third eyelet strip twice by 4 cm, a total of 8 cm to the right.

[0053] Similarly, after the (n-1)th eye plate strip moves to the right and stops, the nth eye plate strip starts to move, i.e. moves to the left to the scale-(8+(n-1)m)cm. Then, the cooperation control of the cylinder and the stepping motor is controlled to move the nth eye plate strip by 4cm twice, i.e. 8cm to the right.

[0054] After the healds are threaded, each eye plate strip is reset.

[0055] Through the cooperation control of the cylinder and the stepping motor and the fact that all the healds are threaded and returned to the original position, it can be ensured that the healds on each column of eye plate strips can be in the middle position, and there is no obstruction when the healds are threaded, and the healds will not be inserted and disordered. After all the healds are threaded, they are returned to the middle position according to the sequence and fixed, which is convenient for the next process of threading the reed.

[0056] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
