Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Industrial field of use) The present invention relates to a weaving device which is used when a warp beam and a member through which a warp thereof is threaded are attached to and detached from a loom. .

(Prior Art) When mounting a warp beam on a loom and passing the warp threads to the weaving machine side, before installing a new warp beam in consideration of shortening the time of the work leading to improvement of the operating efficiency of the loom. A work procedure in which the warp thread is inserted through a plurality of heddle frames in advance is generally adopted.

Japanese Patent Publication No. 57-53899 discloses an example of a device for transporting and transferring a warp beam and a heddle frame in which a warp thereof is inserted. In this device, a pair of left and right lifting columns are equipped with horizontally expandable arms, and a hook member is connected to the tips of both arms. The hook members collectively lock the heddle frame. It is supposed to be hung.

(Problems to be Solved by the Invention) However, since the pair of left and right telescopic arms can extend and contract independently of each other, in order to engage the hook members with the heddle frame, they must be separately extended. There is the complexity of not becoming. Moreover, when the lifting column is raised to pull out the heddle frame, it is necessary to fix both telescopic arms so that they cannot expand and contract, and the operation is troublesome.

Configuration of the Invention (Means for Solving the Problems) Therefore, in the present invention, a transfer member capable of suspending or gripping a plurality of heald frames through which warp threads of a warp beam are inserted is provided in a parallel 6-joint link mechanism. A heddle frame transfer means attached to the front-side straight translation link and a warp beam transfer means for mounting the full warp beam on the loom and removing the empty warp beam from the loom constitute a machine setting device,
A drive screw shaft system is adopted as a drive mechanism for moving the parallel 6-joint link mechanism in straight translation.

(Operation) That is, the forward translational translation link of the parallel 6-bar linkage that constitutes the heddle frame transfer means translates in the direction orthogonal to the drive screw shaft by the forward and reverse rotations of the drive screw shaft,
The transfer member attached to the same link makes a reciprocating linear motion.
Therefore, if the machine working position of the machine-moving device with respect to the loom is set so that the above-mentioned tip-side straight-translation translation link is parallel to the heddle frame mounted on the loom, the tip-side straight-translation translation link will be During the machine setting work, the heald frame is always parallel to the heald frame, so that the transfer member and the heald frame are engaged with each other, the heald frame is pulled out from the loom, and the heald frame is attached to the loom smoothly. In addition, the drive system using the drive screw shaft can achieve high positioning accuracy by the self-deceleration function, and the parallel 6-bar link mechanism can be fixed very easily by the self-locking action of the drive screw shaft system. The stability of the heddle frame is easily ensured during transportation of the frame or when the heddle frame is pulled up.
