Description

[Detailed description of the invention] (Field of industrial application) This invention prevents miscatch and eliminates mistakes in yarn sorting by smoothly and reliably guiding the yarn to the yarn sorting guide when changing the yarn to be wound on the warping cylinder. Regarding sample warping machine with mechanism.

(Conventional technology) Conventionally used sample warping machines include:
The structure disclosed in Japanese Utility Model Application Laid-open No. 49-29242, that is, a driving shaft 2 and a driven shaft 3 are protruded from the center of both ends of a hollow shaft 1, and a small toothed ring fixed to a pulley 4 is attached to the driving shaft 2. 5 and the driven shaft 3 at the other end are loosely fitted with small toothed wheels 7 to which a guiding rod 6 is fixed, and the small toothed wheels 5 and 7 are connected to the small toothed wheels on both ends of the interlocking shaft 8 in the hollow shaft 1. The hollow shaft is supported on one side on the drive shaft 2 side, and the hollow shaft on the driven shaft 3 side is of the same type with alternating arcuate portions 11 and straight portions 12. A warping cylinder is formed by passing a cross beam 16 attached to a conveyor belt 17, which is hung on the trochanter 15 at both ends and moved by sliding across the surface of the cross beam 16, to the circular arc part 11 of the cylinder frames 13, 14 having an outer circumference of . The conveyor belt 17 is driven by a drive element 21 which is screwed into the internal screw shaft 20 of a planetary gear 19 which is rotated all at once by meshing with a master gear wheel 18 which is appropriately driven from outside the cylinder.
A sample warping machine is provided, in which the tips of the thread guiding rods 6 are bent inward and exposed to the upper surface of the front end of the warping cylinder A as the thread guiding section 6'. The structure (the reference numerals are the same as those used in the examples described later) is known. This sample warping machine has been well received for its ability to warp more uniformly and better than other types of warping machines. In this type of warping machine, a plurality of yarn sorting guides 27 are installed, each having a yarn to hold, and these multiple yarns are sequentially transferred to the warping cylinder A according to instructions from a punch card 77 or a program setting device 78. The desired handle is warped by winding it. When a thread change signal is issued when changing the thread to be wound on the warping cylinder, the currently empty thread sorting guide 27 for holding the currently wound thread rotates to the change position and the thread removing device 32, the removed thread is caught by the thread sorting guide 27 that has rotated forward, and the thread sorting guide 27 that caught the thread rotates in the opposite direction and returns to its original position. Then, the other yarn sorting guide 27 holding another yarn rotates forward and the rotating yarn guiding rod 6
The winding of the other yarn by the yarn guiding rod 6 is started, and the empty other yarn sorting guide 27 rotates in the opposite direction and remains empty at its original position. Return. In this yarn change operation, the yarn removed by the yarn removing device 32 is removed from the yarn sorting guide 2.
If the warping machine is not caught by thread 7, it will remain in the thread guiding section 6' and be wound around the warping cylinder A together with the next thread, resulting in a so-called two-wound state, and the warping machine must be stopped to return to the normal winding state. In other words, it becomes necessary to return the material to a single winding, but in conventional sample warping machines, such miscatch accidents occur quite frequently.

(Problems that the invention attempts to solve) This invention was devised in view of the above points.
A long stopper plate S is provided on the base Y corresponding to the yarn sorting guide 27 to limit the rotation of the tip 27a of the yarn sorting guide 27 rotated by the rotary solenoid 29. By making the contact portion of the stopper plate S with the tip 27a of the yarn sorting guide 27 a recessed portion, it is possible to reliably and smoothly guide the yarn to the yarn sorting guide during yarn change or yarn selection, thereby preventing mistakes in yarn sorting. That is, an object of the present invention is to provide a sample warping machine with a miscatch prevention mechanism that can eliminate the occurrence of double winding.

(Means for Solving the Problem) The gist of the present invention is to protrude a driving shaft 2 and a driven shaft 3 from the centers of both ends of a hollow shaft 1, and a small toothed ring fixed to a pulley 4 is attached to the driving shaft 2. 5 and the driven shaft 3 at the other end are loosely fitted with small toothed wheels 7 to which a guiding rod 6 is fixed, and the small toothed wheels 5 and 7 are attached to the small toothed wheels on both ends of the interlocking shaft 8 in the hollow shaft 1. The hollow shaft is supported on one side on the driving shaft 2 side, and the hollow shaft on the driven shaft 3 side is of the same type with alternating circular arc parts 11 and straight parts 12.

Although the movement is performed by mechanical means, it is of course possible to move the pressing body 85 by electric means using known means such as a switch or a motor instead of the handle.

(effect) The operation will be explained below using the above configuration.

First, the number of threads 22 differs depending on the pattern of the sample, but for example, a bobbin of different colors of n colors is placed on the creel B, and the required number of threads 22 is pulled out, and the guide plate 2
4. Pass the thread through the tension adjuster 25, dropper ring 26, and thread sorting guide 27, and press and set it on the base Y using the thread stopper E with a permanent magnet. Next, the yarn guiding section 6' moves circularly on the warping cylinder A at the same time as the main body is operated by using the punch card 77 or the program setting device 78 according to a prearranged arrangement, and winds the yarn 22 on the conveyor belt 17. . conveyor belt 17
is also moved in the direction of the arrow by the action of the internal screw shaft 20. As the pulley 4 rotates, the slit plate 28 generates pulses to operate the n rotary solenoids 29. When the yarn selection guide 27 attached to the rotary solenoid 29 is advanced to the operating position and the yarn selection guide 27 passes through the yarn guiding section 6', the guide rod 3
The thread 22 stretched between 0 and 31 is hooked and wound onto the conveyor belt 17. According to the next instruction from the punch card 77 or the program setting device 78, the thread removing device 32 is activated, and the thread 22 being wound is removed.
Next punch card 77 or program setter 7
Another thread is wound according to the instruction in step 8.

To explain the movement of the yarn 22 during yarn change with reference to FIG. 9, the yarn 22a, which is initially held by the yarn sorting guide 27 in its original position, is moved when the yarn sorting guide 27 rotates. When the thread advances to the operating position, the thread enters the state 22b, and from this state the thread guide section 6'
The thread 22c is wound once on the warping cylinder A, and the thread 22d is wound from the second time onwards.
It is carried out in the state of When the thread 22d being wound is removed by the thread removing device 32, it becomes the thread 22b again. The thread sorting guide 27, which has been rotated and advanced to the operating position in order to catch the removed thread, has its tip 27a located within the recess r of the stopper plate S, so that the removed thread 22b is not caught. The thread sorting guide 27 catches the thread reliably and smoothly, and accidents such as double winding do not occur.

At this time, the thread 22 to be removed, that is, the thread guiding rod 6
When the thread passes through the thread loosening prevention device 60, the sensor 67
b immediately detected by the program setter 7.
8 and the controller 79, the rotary solenoid 66 is turned on, and the rotating disk body 6
2 in the direction opposite to the biasing direction of the spring means 64, and the thread 22 that was located in the thread holding notch 63 is
is pressed down by the end face of the thread holding notch 63 and the stopper 65. This pressed state is canceled for a short time, that is, when the thread guiding rod 6 reaches the position of the sensor 67a, and the thread loosening prevention device 60 is on standby in preparation for when the next thread is removed.

After the removed thread is pressed down by the rotating disc body 62, it is continued to the dropper ring 2.
The yarn sorting guide 27 is returned to its original position while being stretched without loosening due to the weight of the yarn 6, and the yarn is sequentially wound in a predetermined arrangement in anticipation of instructions from the next punch card 77 or program setting device 78.

In addition, when winding, the twilling bars 33, 34,
35 and 37 carry out a twilling action, cut twill bars 36 and 38 separate the twilled yarn into a lower yarn and an upper yarn, and the wound yarn rows are twilled by the action of the cut twill bars 36 and 38. The thread is cut at the cutting part, the lower thread is stopped by a thread stopper 39 attached to the trunk frame 13, and the upper thread is tied to the fabric of a skeleton 40 of a rewinding machine C and wound up via a roller 41. Next, from the roller 41 to the roller 42, the jigzag comb 43, and the roller 44, the woven fabric beam 4
However, since the warping cylinder A of the present invention is almost circular, there is no problem even if the skeleton 40 is wound directly onto the woven fabric beam 49 without unwinding. In addition, when rewinding, after removing the twill bars 33, 34, 35, and 37 and the cut twill bars 36, 38, the pressing body 85
Good rewinding can be achieved by extruding the yarn outward and rewinding it while applying tension to the yarn.

(Effect of the invention) As described above, the present invention provides the yarn sorting guide 2 rotated by the rotary solenoid 29.
A long stopper plate S is provided on the base Y corresponding to the yarn sorting guide 27 to limit the rotation of the tip 27a of the yarn sorting guide 27, and the stopper plate S is connected to the tip 27a of the yarn sorting guide 27. Since the contact portion is a recess, it is possible to reliably and smoothly guide the yarn to the yarn sorting guide during yarn change or yarn selection, and it is possible to eliminate mistakes in yarn sorting, that is, occurrence of double winding. It is something.
