Description

[Detailed description of the invention] Industrial field of application The invention relates to a control device for a woolen card machine, from a breaker card, through an intercard and a finish card, to a capacitor that performs web dividing, rubbing, and winding. .

BACKGROUND TECHNOLOGY AND PROBLEMS Generally, in woolen spinning, a web that has passed through a multi-stage card and exits from a textile fabric is divided into a plurality of pieces and then immediately subjected to rubbing to form rovings. In this respect, worsted spinning involves the convergence of a web into a sliver, the bundling and stretching of multiple slivers, and the subsequent drafting.
Furthermore, unlike the process of repeatedly binding and drawing to create roving yarns to strengthen and homogenize the material, in wool spinning, a fragile web made of relatively short fibers is spun into multiple tape-like slivers. Since dividing is followed by rubbing, it is necessary to pay close attention to these operations. That is, in order to make the diameter and quality of the roving strict and uniform, it is essential to strictly control the feeding speed of the web and tape-like sliver and the winding speed.

In the conventional woolen card machine, as shown in FIG.
20, each cylinder 1 of the finisher card 130
11, 121, 131 are provided with drive motors, and each card document and dividing roller 141 is provided with a drive motor.
The rubber shaft 142 (also see FIG. 6) is driven by gear transmission from each card cylinder motor.

Figure 6 shows the number 13 of the Finiscier card.
The details of the part from 2 to the bobbin via the rubber are shown. As shown in the figure, the web W stripped from the dolphin 132 is received by a capacitor tape 144 driven by a dividing roller 141. A large number of capacitor tapes 144 are arranged in parallel in the width direction. Adjacent capacitor tapes 144 touch the web W from different directions up and down, and are divided into upper and lower parts from the part wound around the dividing roller 141, thereby making the web W into a narrow width. Divide into tape-like slivers V. Capacitor tape 14 divided into upper and lower parts
4 is further divided into upper and lower parts toward the tension roller 145, and passes the tape-shaped sliver V to the rubber 146 at the point where the tension roller 145 passes. Rubber 1
46 is equipped with an upper and lower endless belt driven by a rubber shaft 142, and the endless belt runs so as to move opposing surfaces in the same direction to feed the tape-shaped sliver V while reciprocating in the width direction. The sliver V is rubbed and hardened by moving. This reciprocating motion is obtained on the basis of an eccentric drive shaft (not shown) coupled to the rubber shaft 142. By this feeding and rubbing in the rubber 146, the tape-shaped sliver V is turned into a roving s, which is wound onto a rotating bobbin 147 with its surface in contact with the turnpole 143. During wool spinning, the raw material supply rate of the hopper feeder 100 and the rotation speed of rollers such as the dower and walker for each card are determined according to the properties of the raw fiber, the count of the roving, the spinning speed of the roving, etc. The rotational speed of the eccentric drive shaft that reciprocates the stitch card document fur 132, the dividing roller 141, the rubber shaft 142, the turn pawl 143, and the rubber is determined based on the following detection in order to optimize the diameter and quality of the roving s. This adjustment was made by rearranging the gear train from the drive motor to the rotating shaft. That is, visually check the amount of drooping from the horizontal line at the transition part of the web W from the dot fabric to the capacitor tape and the entrance angle of the tape-shaped sliver at the transition part of the tape-shaped sliver V from the capacitor tape to the rubber, and also check the roughness of the tape-shaped sliver from the rubber to the turn pole. thread s
It is based on the detection of various quantities by visually observing the tension of the roving at the transition part and determining the rolling stiffness of the roving s wound around the bobbin 147 by pressing it by hand. Recombining this gear train requires a lot of effort and time, and in particular, changing the rotation speed on the upstream side of the finisher card, etc., affects the downstream side, so it is necessary to recombine the gear train on the downstream side each time. This problem was a big one because it also required Moreover, since the raw material continues to flow through the carding machine during this adjustment, there is also the problem that the total amount of defective rovings generated by the time the adjustment is completed becomes large.

The present invention solves these problems and provides a woolen card that can quickly and easily adjust the rotational speed of cylinders, rollers, etc. in a woolen card machine, and that can reduce the total amount of defective rovings generated during adjustment. The purpose is to provide a control device for machines.

Means for Solving the Problems The object of the present invention is to provide a control device for a woolen card machine from a breaker card, through an intercard and a finisher card, to a capacitor for dividing, rubbing and winding the web. A first rotating member group consisting of a card cylinder, an intercard cylinder, a finisher card cylinder, and an eccentric drive shaft for repetitive movements in rubbing, a second rotating member group consisting of dosing and dividing rollers, and a rubber shaft and winding. a frequency setter provided in common to each rotary member group for a third rotary member group consisting of turn poles; an inverter-controlled drive motor that is controlled by the frequency setter and drives and rotates each of the rotary members; a detection unit that detects the rotational speed of at least one rotating member in each rotating member group; a display unit that displays the rotational speed detected by the detection unit or the rotational member circumferential speed calculated from the rotational speed; first, second and third operating sections for manually operating frequency setting devices provided on the first, second and third rotating member groups; and a fourth operating section for controlling the third operating section simultaneously and in proportion to each other.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a state in which a drive motor 1 whose rotation speed is controlled by an inverter is connected to a rotating member 3 via a reduction gear 2. As shown in FIG. This rotating member 3
corresponds to the dividing roller, rubber shaft, etc. in the card machine shown in FIG. ), and a common inverter frequency setter is provided for each of the following groups.

First rotating member group: breaker card cylinder 11
1. Intercard cylinder 121, finisher card cylinder 131, eccentric drive shaft, second rotating member group: finisher card cylinder 132, dividing roller 141, third rotating member group: rubber shaft 142, winding turn pole 143.

Note that other rotating members such as the dots in the breaker card and intercard are driven from the drive motor for each of the rotating members via appropriate transmission mechanisms such as gears and belts.

In each of these rotating member groups, at least one rotating member is provided with a detection unit 4 for detecting the number of rotations. The detection unit 4 consists of a disk 40 with a large number of small holes fixed to a rotating shaft as shown in FIG. 2 and an optical rotation sensor 41 that cooperates with the disk, and a rotating member as shown in FIG. 3. Drive gear 42
and a magnetic rotation sensor 43 that cooperates with the gear. As the detection unit 4,
In addition, a mechanical or electrical tachometer may be used as appropriate. In this example, the rotational speed detection targets are the breaker card cylinder, intercard cylinder, finisher card cylinder, eccentric drive shaft, finisher card cylinder and dividing roller in the second rotating member group in the first rotating member group. , a rubber shaft in the third rotating member group, and a turn pole for winding. The detected rotational speed is calculated as the rotational speed or as a product of the member diameter. It is displayed by the display unit as the member circumferential speed. For frequency setting devices provided in the first, second, and third rotating member groups, the first, second, and third
An operation section (not shown) is provided in each case. Therefore, when operating the card machine, the number of rotations or circumferential speed of the members displayed on the display section is visually checked, and each rotating member is rotated appropriately via the frequency setting device and the inverter-controlled motor by operating the operation section. The speed can be adjusted. This adjustment is performed based on the optimum value corresponding to the properties of the raw material fiber, the count of the spun roving, etc. This control device is further provided with a fourth operating section for proportionally controlling the first, second, and third operating sections simultaneously, and by operating the operating section, the rotational speeds of all rotating members are mutually controlled. It is possible to change the rotation ratio while maintaining it. A control block diagram for each of these rotating members, operating sections, etc. is shown in FIG. Here, as the first to fourth operation parts, ordinary adjustment means for changing the voltage or current to the frequency setter based on manual operation can be adopted.

Functions and Effects In the control device for a woolen card machine according to the present invention, as in the above embodiment, the various card cylinders, shafts, etc. are composed of a breaker card cylinder, an intercard cylinder, a finisher card cylinder, and an eccentric drive shaft for rubbing. a first rotating member group, a second rotating member group consisting of a finisher card document and a dividing roller;
It is divided into a third rotating member group consisting of a rubber shaft and a winding turn pole, and each rotating member group is provided with a common frequency setting device and placed under common control. Here, the first rotating member group consists of rotating members for repeated operations for carding and rubbing, and since the accuracy of controlling the rotation speed of these members has a relatively small effect on the diameter and quality of the roving, the number of rotating members is Collective control is possible and efficient. Next, since the speed and speed of the rotation of the second rotating member group is directly reflected in the thickness of the web and, ultimately, the diameter of the roving, strict control can be achieved by controlling it independently from the first rotating member group. becomes possible. In addition, the dividing roller should receive the web sent out at a speed proportional to the number of rotations of the dosing fur at a speed proportional to this, so it is possible to control the number of revolutions in common with the dossier, and this sharing is efficient. be. Next, the rotation speed of the rubber shaft in the third rotating member group determines the speed at which the tape-shaped sliver formed by the dividing roller is conveyed during the rubbing process, which determines the final roving diameter and quality. Therefore, stricter control can be achieved by controlling independently from the second rotating member group. Also, the turnpole
The roving, which is carried out at a speed proportional to the rotation speed of the rubber shaft, should be wound up at a speed proportional to this, so it is possible to control the rotation speed in common with the rubber shaft, and this commonality is efficient. . In this way, according to the control device of the present invention, the first, second and third
We divide the rotating parts into groups necessary for machining accuracy.
The detection unit detects the rotational speed of at least one rotating member in each rotating member group, and the display unit displays the detected amount, making it possible to control each rotating member group based on the displayed value. , ensuring spinning precision and improving control efficiency. For this control operation, in addition to the first, second and third operating sections, a fourth operating section is provided which controls these operating sections simultaneously and in proportion to each other, thereby speeding up the operation.

As described above, according to the present invention, the number of revolutions of cylinders, rollers, etc. in a woolen card machine can be adjusted quickly, easily and efficiently, and the total amount of defective rovings generated during adjustment can be reduced. A control device for the machine can be provided.
