Abstract

(57) [Summary] [Purpose] To provide a condenser whose sliver regulation width is variable and which is not bulky in the traveling direction of the sliver, and to narrow the interval between draft rollers when the fiber length is short like card cotton.

[Configuration] A pin holding member having a plurality of pin insertion holes,
The sliver passage is composed of a pin that can be inserted into and removed from the pin insertion hole, and the gap between the pins inserted into the pin insertion hole is a sliver passage.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mechanism of a draft device capacitor in a spinning device, that is, a mechanism for restricting the width of a drafted sliver at a nip point entrance portion of a draft part.

[0002]

[Prior Art]

 In the draft device, the width of the sliver to be drafted tends to increase every time the roller or apron is passed, and if it is left unattended, the intended draft will not be performed uniformly. Therefore, a sliver width regulation guide called a condenser is often installed at the entrance of the apron draft device.

Conventionally, as this capacitor, a funnel-shaped grooved body having an open upper end or a plate material having a notch of a certain width is used, and the funnel-shaped portion thereof is used. Alternatively, the notch is installed in the sliver passage so that the sliver passes through, and the vertical edge of the notch regulates the spread of the sliver.

However, since the suitable width of the drafted sliver changes depending on the spinning count, a sliver regulation width of about 2 mm to a dozen mm or more must be prepared in preparation for changing the spinning count. Moreover, there is a problem that it takes a lot of time to replace the capacitor each time the count is changed.

However, the conventional condenser is bulky in the traveling direction of the sliver, so that there is a problem that it cannot cope with the case where the distance between the draft rollers is narrowed.

[0006]

[Problems to be solved by the device]

 Therefore, the present invention provides a condenser whose sliver regulation width is variable and which is not bulky in the traveling direction of the sliver, and can narrow the gap between the draft rollers when the fiber length is short like card cotton. It is possible, and it is intended to facilitate the handling when the spinning number is changed even though the cotton wool is less likely to collect before and after the condenser.

[0007]

[Means for Solving the Problems]

 A sliver passage is defined by a pin holding member provided with a plurality of pin insertion holes and a pin inserted into the pin insertion hole, the pin being inserted into and removed from the pin insertion hole.

[0008]

[Action]

 In the capacitor of the present invention, the sliver is passed through the gap between the pins formed by the two pins inserted into the pin insertion holes of the pin holding member. However, the pin-to-pin spacing can be adjusted by selecting the pin insertion position. Change the sliver width regulation value.

Further, since the pin holding member only needs to have a width sufficient to provide the pin insertion hole, the width in the traveling direction of the driver can be minimized and the distance between the draft rollers can be narrowed.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

The capacitor 1 of the present invention is interposed between the roll pairs 2 and 3 of the draft device, and the pin holding member 4 is detachably supported by the frame by a mechanism (not shown). Then, on the upper surface of the pin holding member 4, a plurality of pin insertion holes 5 are provided in one row in the longitudinal direction of the pin holding member 4 at equal intervals. 6 is a pin that can be inserted into and removed from the pin insertion hole.

Therefore, in the capacitor 1 of the present invention, two pins 6a and 6b are inserted into the pin insertion holes 5a and 5b of the pin holding member 4 as shown in FIG. The width of the sliver is regulated by passing the sliver through the gap 7 between the pin 6a and the pin 6b which is formed by changing the distance between the pin 6a and the pin 6b by selecting the insertion position of the pins 6a and 6b. The sliver width regulation value can be changed.

Further, when two slivers traveling in parallel are drafted by one unit of draft device, as shown in FIG. 3, the pin insertion holes 5a, 5b, 5c, 5d of the pin holding member 4 are The width of the sliver can be regulated by passing the sliver through the gaps 8 and 9 formed by the four pins 6a, 6b, 6c and 6d respectively inserted into the pins 6a and 6b, 6c and 6d. Of course, the width regulating value of the sliver can be changed by selecting the insertion positions of the pins 6a, 6b, 6c, 6d.

Furthermore, since the capacitor 1 of the present invention has the above-mentioned configuration, when the width 10 of the pin holding member 4 is set to the minimum width for providing the pin insertion hole 5, the draft rollers 2, 3 are provided. The interval between can be greatly reduced, and the cotton dust can be prevented from collecting before and after the condenser.

[Effect of the device]

 The capacitor according to the present invention comprises a pin holding member having a plurality of pin insertion holes and a pin which can be inserted into and removed from the pin insertion hole, and a sliver passage is provided between the pins inserted into the pin insertion hole. Therefore, by using this, it becomes possible to extremely easily change the regulation value of the sliver width that enters the draft device when the spinning number is changed, and it is necessary to replace the conventional sliver width. Not only is the working time significantly shortened compared to the case where capacitors are used, but it is not necessary to have a large number of capacitors with different sliver width regulation values all the time, and the cost can be reduced.

Further, since the pin holding member only needs to have a width sufficient to provide the pin insertion hole, the width in the running direction of the sliver is minimized, and when the fiber length is short for card cotton, It is possible to reduce the distance between draft rollers so that uneven raft is less likely to occur, and to prevent fly cotton from accumulating before and after the capacitors (pins) during spinning.
