Problems solved by technology

In addition, in the case of a winding device in which a winding roller having a driving device is brought into contact with a non-driven package and the package is driven to rotate like the stretch false twisting machine described in Patent Document 1, if the If the contact pressure between the package and the winding roller is set low, it is difficult to transmit the driving force that rotates the heavy package due to the friction between the package and the winding roller, and there is a gap between the package and the winding roller. Slipping, resulting in rotational misalignment
[0010] In addition, when the package is full, the mechanism for automatically rotating the cradle to a predetermined position is complicated, and the structure of the automatic doffing device becomes complicated.
In addition, since the package is heavy when fully wound, there is also a problem that the automatic doffing device must adopt a strong structure corresponding to the weight of the package.

Embodiment Construction

[0026] As an example of a textile machine according to an embodiment of the present invention, an example in which the present invention is applied to a draw false twisting machine will be described. First, the schematic configuration of the stretch false twisting machine 100 will be described.

[0027] like figure 1 As shown, the stretch false twisting machine 100 includes a plurality of processing units (each processing unit may be referred to as a "spindle"). Multiple processing units along with figure 1 The vertical direction of the paper is juxtaposed. Each spindle includes a yarn supplying section 1A, a processing section 1B, and a winding section 1C in order from the upstream side toward the downstream side in the running direction of the yarn Y. In the yarn supplying section 1A and the winding section 1C, a plurality of spindles are arranged in parallel in the vertical direction and the horizontal direction in order to reduce the installation space.

Abstract

PROBLEM TO BE SOLVED: To provide a textile machine which can set the contact pressure of a contact roller without being affected by the weight of a package, and can suppress the vibration of the package even if the contact pressure is set to a low value.SOLUTION: In a textile machine, a plurality of take-up devices 10 are vertically and horizontally juxtaposed to each other. Each of the take-up devices 10 includes a cradle 11 which supports a take-up tube B for taking up yarn Y and drives and rotates the take-up tube B at a fixed position, and a contact roller 15 which is brought into contact with a yarn layer formed around the take-up tube B and swings according to the wound thickness of the yarn layer in a state of maintaining the contact with the yarn layer.

Description

technical field [0001] The present invention relates to a textile machine provided with a plurality of winding devices along the vertical and horizontal directions. Background technique [0002] Conventionally, stretch false twisting processing machines are known as textile machines that are provided with a plurality of winding devices in vertical and horizontal directions. The stretch false twisting machine includes a plurality of processing units (spindles), and each processing unit includes a winding device (see, for example, Patent Document 1). [0003] The winding device provided in the stretch false twisting machine described in Patent Document 1 includes a cradle and a winding roller, respectively. The cradle is free to swing and rotatably supports the winding tube for winding the yarn. The winding roller makes contact with the package to drive the package into rotation. The cradle swings corresponding to the thickening of the package on which the yarn layer is for...
