The package storage section is arranged on one side of a vertical plane that passes through the axis of the bobbin holder supported by the cradle in the open position. The storage unit in the aforementioned standby position is positioned on the other side of the vertical plane, The winding device is characterized in that the moving mechanism linearly moves the stocker between the standby position and the supply position.
The stocker is provided with a restricting section at the front end closest to the cradle in the open position, which can be switched between a restricting state that prevents the bobbins stored in the stocker from falling out of the stocker and an open state in which the restricting state is released. The winding device according to claim 1, characterized in that the restricting portion is released when the stocker reaches the supply position.
The stocker has a first rotation axis along the axial direction of the bobbin holder, The aforementioned regulatory body, It has a contact portion that can come into contact with the bobbin holder supported by the cradle in the released position, As the stocker moves from the standby position to the supply position, the contact portion is pressed against the bobbin holder, causing it to rotate in a first direction around the first rotation axis, switching from the restricted state to the released state. The winding device according to claim 2, characterized in that as the stocker moves from the supply position to the standby position, the contact between the contact portion and the bobbin holder is released, causing it to rotate in a second direction opposite to the first direction around the first rotation axis, thereby switching from the open state to the restricted state.
The stocker has a stopper to which the restricting portion, which rotates in the first direction, can make contact. The winding device according to claim 3, characterized in that when the stocker reaches the supply position, the restricting portion, which rotates in the first direction when the contact portion is pressed against the bobbin holder, is restricted from further rotation in the first direction by contacting the stopper.
The winding device according to claim 2, wherein a second restricting part is provided in the stocker to prevent the bobbin stored in the stocker from flying out beyond the bobbin holder when the stocker reaches the supply position and the restricting part is in the released state .
The winding device according to claim 3, wherein a second restricting part is provided in the stocker to prevent the bobbin stored in the stocker from flying out beyond the bobbin holder when the stocker reaches the supply position and the restricting part is in the released state .
The winding device according to claim 4, wherein a second restricting part is provided in the stocker to prevent the bobbin stored in the stocker from flying out beyond the bobbin holder when the stocker reaches the supply position and the restricting part is in the released state .
Of the stocker, the front end closest to the cradle in the open position is provided with a front end support portion that supports the bobbin from below. The front end support portion is capable of adopting a restrictive position to prevent the bobbin from falling out of the stocker, and is rotatable about a second rotation axis along the axial direction of the bobbin holder. The storage unit further includes a biasing member that biases the front end support portion to the restricting position, The winding device according to claims 1 to 7, characterized in that the front end support portion is pressed by the bobbin supported by the cradle in the released position when the stocker moves from the supply position to the standby position, and rotates around the second rotation axis in opposition to the biasing force by the biasing member so as to avoid the bobbin.

Description

This invention relates to a winding device. Patent Document 1 discloses a false twisting machine comprising a false twisting device for imparting false twist to yarn supplied from a yarn feeding unit, and a winding device for winding the false twisted yarn. The winding device has a cradle that rotatably supports a set of bobbin holders, and winds the yarn onto bobbins (paper tubes in Patent Document 1) mounted on the bobbin holders to form a package. In such a winding device, when a fully wound package is formed, the package is removed from the cradle, and a new bobbin is supplied to the cradle. Patent Document 2 describes a winding device (duffing device) having a package storage section (guide rail in Patent Document 2) that supports the package removed from the cradle, and a stocker (paper tube stocker in Patent Document 2) that houses multiple empty bobbins lined up for supply to the cradle. In the winding device described in Patent Document 2, the stocker is pivotably supported on a rotating shaft located below the stocker via a support bracket. During yarn winding, the stocker is positioned in a standby position above the package storage section (as shown in Figure 2). When supplying bobbins to the cradle, it pivots around the rotating shaft to move to a supply position below the standby position and on the right side of Figure 2 in Patent Document 2 (hereinafter simply referred to as the right side; similarly, the left side of the page is simply referred to as the left side). Japanese Patent Publication No. 2011-47074Japanese Patent Application Publication No. 9-86799 This is a schematic side view of the false twisting machine according to this embodiment.This is a schematic diagram showing the configuration of a winding device.This is a schematic diagram of the winding mechanism when the cradle arm is moved to the release position.This is a schematic diagram of the winding device when the stocker moves to the supply position.This is a partial perspective view showing the configuration of the front part of the storage unit.This diagram shows a stocker in transit from the standby position to the supply position.This diagram shows the stocker when it reaches the supply position. The embodiments of the present invention will be described below with reference to the drawings. (Overall configuration of false twisting machine 1) Figure 1 is a side view showing the schematic configuration of the false twisting machine 1 according to this embodiment. Hereinafter, the direction perpendicular to the plane of Figure 1 will be defined as the machine frame length direction, and the direction from left to right on the plane of Figure 1 will be defined as the machine frame width direction. The direction in which both the machine frame length direction and the machine frame width direction are perpendicular will be defined as the vertical direction in which gravity acts. Hereafter, the above directional terms will be used as appropriate in the explanation. The false twisting machine 1 is configured to perform false twisting on yarn Y made of synthetic fibers such as nylon (polyamide fiber). The false twisting machine 1 includes a yarn feeding section 2 for supplying yarn Y, a processing section 3 for false twisting the yarn Y supplied from the yarn feeding section 2, and a winding section 4 for winding the yarn Y processed by the processing section 3 onto a bobbin Bw. The components of the yarn feeding section 2, processing section 3, and winding section 4 are arranged in multiples along the longitudinal direction of the machine frame, perpendicular to the yarn running surface (plane of paper in Figure 1) where the yarn path from the yarn feeding section 2 through the processing section 3 to the winding section 4 is located. (Yarn feeding section 2) The yarn feeding section 2 has a creel stand 7 that holds multiple yarn feeding packages Ps and supplies multiple yarns Y to the processing section 3. The processing section 3 is configured with the following components arranged in order from the upstream side in the yarn travel direction: a first feed roller 11, a twisting guide 12, a first heating device 13, a cooling device 14, a false twist device 15, a second feed roller 16, an entanglement device 17, a third feed roller 18, a second heating device 19, and a fourth feed roller 20. The winding section 4 winds the yarn Y, which has been false twisted in the processing section 3, onto a bobbin Bw using a winding device 21 to form a winding package Pw. Furthermore, the false twisting machine 1 has a main machine base 8 and a winding base 9, which are spaced apart in the width direction of the machine base. The main machine base 8 and the winding base 9 extend to approximately the same length in the longitudinal direction of the machine base and are positioned facing each other. The upper parts of the main machine base 8 and the winding base 9 are connected by a support frame 10. Each device constituting the processing s
