Abstract

PURPOSE: To provide a tension pulley device simplified by a single kind of tension pulley and useful for a spinning frame and a doubling and twisting frame. CONSTITUTION: This device comprises a tension pulley 3 having a rotating shaft and having a check collar 9 on one end side of an asymmetrically mounted shell 5 covering a bearing unit 4. A supporting piece 2 on a holder 1 is alternately attached to the bottom and the top in order to make the tension pulley 3 stand erect and support suspension thereof.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a tension pulley device for a spinning machine and a plying machine.

[0002]

2. Description of the Related Art A tension pulley for driving a tangential belt of a spinning machine or a ply twisting machine, the tension pulley being held by an elastic holder, the holder being held by the machine body at the center, At the free end, a tension pulley with a check collar for the tangential belt presses the tangential belt against the spindle and the running of the tangential belt is staggered from above and below by the check collar. Tension pulley devices that are cantilevered are known.

The tension pulley is used to press the tangential belt against the spindle of a spinning machine or a twisting machine. These tension pulleys are held so as to form a pair at both ends of the elastic holder, and both are arranged so as to be located between the two spindles. In particular, when the machine is assembled and commissioned, the tension pulley shell should be kept in place to prevent the tangential belt from traveling upwards or downwards due to a series of incorrectly aligned tension pulleys. Has a check collar for the tangential belt.

As a tension pulley of this kind, DE3
There is one disclosed in 106307A1.

[0005]

One drawback of this known tension pulley device is that the two tension pulleys differ from each other in order to provide a check collar for the tangential belt at the bottom and top of the tension pulley. It means that it must be shaped. If the shell is vertically asymmetrical, this is especially necessary for tension pulleys with a plastic shell with a rotating shaft to save energy, but when the check collar is located on the short barrel side of the shell. The shell cannot be said to be sufficiently stable.

It is an object of the present invention to provide a tension pulley for a spinning machine and a plying machine which is a single type tension pulley and can be provided with check collars for tangential belts alternately at the top and bottom of the shell. To do.

[0007]

According to the present invention, as the first means for solving the above-mentioned problems, a tension pulley having a rotating shaft covers one end of a shell which covers a bearing unit and is mounted asymmetrically. This is accomplished by having check collars and supporting pieces on the holder mounted alternately on the bottom and top for upright and suspension support of the tension pulley.

Further, as a second solution, a tension pulley having a rotary shaft has a check collar at one end side of a shell which covers the bearing unit and is mounted asymmetrically, and the tension pulley is provided on the same side. It is also achieved by having the holder on one side attached to the fuselage as an upright and suspension pair of tension pulleys.

The common point of the above two kinds of solution means is that a tension pulley having a check collar for a tangential belt is used on the long cylindrical portion side of an asymmetric shell. Thus, plastic tension pulleys are more stable.

The first solution is advantageous in that the support piece can also be of a single type.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 is an elastic holder having support pieces 2 at both ends. The tension pulleys 3 and 3 are
It is supported in a cantilever manner on each of angle-shaped support pieces 2 and 2 which are alternately attached at the upper end and the lower end in the figure. By firmly holding the support piece 2, one of the two tension pulleys 3 is vertically erected upright and the other is suspended downwardly.

The tension pulley 3 is a bearing unit 4
And a shell 5 held by a web 6 provided asymmetrically with respect to the direction of the stub shaft 7 of the bearing unit 4. This asymmetrically arranged web 6 is necessary so that the shell 5 can completely cover the bearing unit 4 without raising the tension pulley more than necessary to drive the belt. In the long tubular portion of the shell 5 that is pressed against the tangential belt 8 (see FIG. 2),
A check collar 9 for the tangential belt 8 is provided. For manufacturing reasons, the shell 5 is provided with one check collar 9 by plastic molding.

FIG. 2 shows the mounting of the elastic holder 10 on a spinning machine (not shown) by means of an angled bracket 10 and the arrangement of a tension pulley on a spindle 11 with a tangential belt 8.

The arrangement of the tension pulleys 3 is shown in FIG. 3, with the tension pulley check collar 9 at the bottom of the fuselage, at the bottom and then the top of one shell 5, It is provided in the form as shown in FIG.

FIG. 4 shows a modification of the tension pulley 3, which is attached to the supporting piece 2 on the same side. With such a configuration, the holder 1 can be attached to the machine body in any form of the tension pulley 3 such as the upright type or the suspension type. Even with this solution, the tangential belt is prevented from slipping off due to the pair of check collars 9 alternately arranged at the bottom and the top.

After the attachment is completed, that is, when the plurality of tension pulleys 3 are arranged in a line, the tangential belt 8 does not come into contact with the check collar 9 up to about 30 m / s.
