Description

[Detailed description of the invention] The present invention is a top calender in a calender roller device that forms fleece sent out from the drafting section of a wire drawing machine into a sliver via a convergence guide, etc., and sends out the sliver toward a coiler below. This invention relates to a roller device.

The top calender roller in a conventional wire-stretching machine has bearing parts such as end bushes fitted to both its left and right shafts, which are fitted into grooves in the left and right roller stands to be supported on both the left and right sides. A pressure device attached to the side presses the rear bottom calender roller, and the high-speed rotating bottom calender roller is also actively driven via gears to send the focused sliver toward the coiler below.

In this calender roller device, which sends out the sliver collected by the high-speed bottom calender roller and top calender roller toward the coiler below, one of the top calender rollers is elastically moved back and forth through a pressure device using a spring. The top calender roller is supported so that it can move back and forth to follow changes in the thickness of the sliver being sent out.

Further, the sliver fed out by the double-force render roller usually has more than a few variations in thickness, and due to variations in the thickness of the sliver, the top calender roller constantly vibrates slightly in the front and back direction during operation.

For this reason, fretting occurs in the bearings of the end bushes fitted to both shafts of the top calender roller and in the concave grooves of the roller stand, and the fine powder caused by the fretting can rust or wear the mating surfaces. When a step was formed in the concave groove, the top calender roller stopped moving back and forth following the change in the thickness of the sliver to be sent out, and the pressure cuff 5 against the sliver changed, causing deterioration of the spun sliver.

In view of the current state of the wire-stripping machine, the present invention incorporates a plurality of bearings at appropriate intervals on the shaft of one side of the top calender roller, which is installed in parallel in front of the bottom calender roller located above the coiler head. A gear that meshes with the gear of the bottom calendar roller is wedged on the shaft portion of the housing through the notch of the inserted housing, and a gear of an appropriate length in the vertical direction is attached to the outer end of the housing. Attach an end cap with a boss part, and fit both end faces of the boss part of the end cap into the fitting parts of a bracket fixed to the outside of the roller stand to regulate the position in the vertical direction, and Pivots are inserted into vertical holes drilled in the boss part and the bracket respectively...The housing and the top calender roller are supported in a cantilever manner, and the top calender roller is made to be able to swing in the horizontal direction. The top calendar roller is forced to come into pressure contact with the rear bottom calendar roller through the pressure contact state, and a gap is provided between the housing of the top calendar roller and the roller stand in the state of pressure contact, thereby eliminating fretting caused by slight vibrations of the top calendar roller. The object of the present invention is to provide a calender roller device for a filament machine.

Hereinafter, the present invention will be explained with reference to an embodiment shown in the drawings.

1 is a bottom calender roller placed above the coiler head 2 of the coiler; left and right roller stands 3A, 3;
It is pivotally supported via a bearing 4 fitted in B, is connected to a drive source via a gear train (not shown), and rotates at high speed in the direction of the arrow shown in the drawing.

5 is a gear for driving a top calendar roller 6, which will be described later.

Reference numeral 6 denotes a top calender roller arranged in parallel in front of the bottom calender roller 1 on one side thereof (on the left side in FIG. 1).
A housing 8, in which a plurality of bearings 7A, 7B are installed at appropriate intervals, is inserted into the shaft portion of the housing and positioned in the axial direction.

In addition, when inserting the housing 8, the notch 8 of the housing 8 is used.
A gear 9 that meshes with the gear 5 of the tom calender roller 1 is wedged through a.

Further, an end key 0 having a boss portion 10a having a length in the vertical direction (vertical direction in FIG. 1) is attached to the end of the cap, and both end surfaces of the boss portion 10a of the end cap 10 It is fitted into the fitting part 11a of the bracket 11 fixedly installed on the outside of the roller stand 3A via the upper and lower thrust metals 12A and 12B, and its position is regulated in the vertical direction, and the boss part 10a of the end cap 10 and the bracket Vertical vertical holes 10b drilled in 11, and vertical holes 11a with metals 13A and 13B interposed therein,
A pivot shaft 14 is fitted into the end cap 11b, and the pivot shaft 14 is fixed by a set screw of the end cap 10.

In addition, the above thrust metals 12A, 12B and metal 1
3A and 13B may be omitted, and the end cap 10 and pivot 14 may be inserted directly into the bracket 11.

Alternatively, the pivot 14 may be fixed to the bracket 11, and the end cap 10 may be rotatably inserted into the fixed pivot 14.

In this case, it is preferable to interpose a metal between the end cap 10 and the pivot 14.

This allows the housing 8 and the top calender roller 6 to
is supported in a cantilever manner via a vertical pivot 14 and is capable of swinging in the horizontal direction.

At the shaft end of the top calender roller 6 on the other side (the right side in FIG. 2), which is supported in a cantilever manner and is configured to be able to swing in the horizontal direction, there is provided another housing 16 in which a bearing 15 is installed. is fitted, and the top calender roller 6 is pressed against the rear pot uneven renderer 0-ra 1 by a detachable pressure device 17 provided on the front side of the roller stand 3B on the other side of the no-uji puffer fish 16. ing.

Ugings 8 and 1 are fitted on both sides of the top calender roller 6 which is in pressure contact with the bottom calender roller 1.
6 denotes each corresponding roller stand 3 as shown in the figure.
A.

Appropriate gaps 18 and 19 are provided between the roller stands 3A and 3B so that they do not come into contact with the roller stands 3A and 3B.

In the top calender roller device of this embodiment configured as described above, the top calender roller 6 rotates in synchronization with the high-speed rotation of the bottom calender roller 1 via the gears 5 and 9, and directs the focused sliver to the coiler below. In this case, the top calender roller 6 vibrates slightly due to variations in the thickness of the sliver to be sent out, but gaps 18 and 19 are created between the housings 8 and 16 fitted on the shafts on both sides and the roller stands 3A and 3B. 7 retting does not occur, and the amplitude at the pivot shaft 14 is less than 1/20 of the amplitude of the top calender roller 6, making the metal 13A.

7 retting is never expressed in 13B.

Furthermore, since the top calender roller device of this embodiment is configured to be able to swing around the pivot 14, the top calender roller 6 can be easily separated from the bottom calender roller 1 simply by disengaging the pressure device. This makes it possible to easily perform the sliver wrapping work and the winding removal work.

The present invention is not limited to the above-mentioned embodiment, but the shaft portion and housing 16 on the other side (right side in FIG. 2) of the top calender roller 6 in the above embodiment are eliminated, and the roller stand on the left side in FIG. A pressure device may be attached to the 3A side to press the top calender roller to the bottom calender roller via the housing 8.

As described above, the present invention has the top calender roller, which is actively driven and rotates at high speed, cantilever-supported via a vertical axis and is also swingable in the horizontal direction, and the housing of the top calender roller is in pressure contact with the bottom calender roller. Since the top calender roller device of the filament machine is constructed by providing a gap between the roller stand and the roller stand, fretting does not occur between the housing and the roller stand and at the axis due to slight vibrations of the top calender roller, resulting in stable quality. sliver can be spun over a long period of time.

Furthermore, since the top calender roller is swingable, the sliver machining process can be easily performed.
