Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a warp beam support device for a loom.

(Prior art) As a warp beam support device for a loom,
The structure consists of a support bracket for placing the warp beam attached to each side frame of the loom, and a clamp member that clamps and holds the warp beam on the same bracket, and the clamp member clamps the bearings at both ends of the warp beam. It is rotatably connected to the support bracket so as to be switchable between a holding position and a releasing position. In a warp beam support device having such a configuration, when attaching or detaching the warp beam from the loom, it is necessary to rotate the clamp member from the clamp holding position to the release position and to hold the clamp member at the release position. In the conventional device disclosed in Japanese Utility Model Application Publication No. 56-28085, the clamp member is manually rotated and held in the released position by its own weight.

In addition to the methods described above, methods for holding the clamp member in the released position include a method in which a hook attached to the clamp member is latched to a predetermined latching portion, a method in which the clamp member is latched to a predetermined spring-type latching portion, etc. is possible.

(Problem to be solved by the invention) However, all of these release posture maintaining methods not only require manual operation in the release operation, but also the reverse operation, which is the transition operation from the release position to the clamp position. However, manual operation of the clamp member near the warp beam flange where space is limited is not only difficult but also poses a problem in terms of worker safety. In addition, in recent years, as warp beams have become larger, that is, warp beam flanges have become larger in diameter, the above-mentioned manual operations for attaching and removing warp beams to and from looms have become increasingly difficult. The smoothness is significantly impaired.

Structure of the invention (Means for solving the problem) Therefore, in the present invention, the bearings are releasably clamped in the warp beam removal direction on a warp beam mounting member that supports the bearings on both ends of the warp beam. The object is a warp beam support device having a structure in which a clamp member is rotatably attached, and includes a release maintaining position where the clamp member is maintained in a released state following the removal and mounting operations of the warp beam, and a return state where the release state is canceled. A release posture maintaining member that can reciprocate between positions is provided at the warp beam attachment position.

(Function) That is, the release attitude maintaining member is moved to the release attitude maintaining position following the removal operation of the empty warp beam being taken out from the mounting position on the warp beam mounting member, and the warp beam is taken out and the above-mentioned warp beam is removed. The clamp member is maintained in the released position. Subsequently, when a full warp beam is placed on the warp beam mounting member and rolled toward the mounting position, the release posture maintaining member maintains the release posture following the mounting operation of the full warp beam. Return from position to standby position. Therefore, the rotation operation of the clamp member and the maintenance of the released position are automatically obtained from the rolling operation of the warp beam on the warp beam mounting member, and the operations of taking out and mounting the warp beam are smooth and safe.

(Example) Hereinafter, examples 1 to 3 that embody the present invention will be described.
This will be explained based on the diagram.

A mounting recess 2a for mounting the warp beam is formed at the upper end edge of a bracket 2 for mounting and supporting the warp beam attached to the rear part of the side frame 1 of the loom (only one side is shown in the drawing).
A guide groove 2b is formed that connects to the recess 2a. The mounting recess 2a fits and matches the bearings 3a at both ends of the warp beam shaft 3, and the guide groove 2b rolls and guides the bearings 3a. In addition, in FIG. 1, 4 indicates the entire empty warp beam, and T indicates the warp threads. A semi-circular clamp member 5 is rotatably attached to the base end side of the mounting recess 2a, and its distal end side is tightened and joined by a bolt 6 onto the guide groove 2b. The inner circumferential arc of the clamp member 5 fits and matches the bearing 3a,
Its tip A is set above a line L passing through the center of the warp beam axis 3 and parallel to the guide groove 2b.

A bar 7 is rotatably attached to the inner surface of the clamp member 5, and a position regulating part 5a is formed in a protruding manner to regulate the rotational position of the bar. A tension spring 8 is hung between them. As shown in FIG. 1, when the empty warp beam 4 is installed, the bar 7 is rotatably pressed onto the warp beam axis 3 by the tension spring 8.
The length of the bar 7 is set so that the tip of the bar 7 does not reach the guide groove 2b in the state shown in FIG.

In an embodiment with such a configuration, if the empty warp beam 4 is pulled in the take-out direction after the bracket 2 and bolt 6 are completely unscrewed, this take-out force is transmitted through the upper outer periphery of the bearing 3a. This acts on the tip position A of the inner circumferential arc of the clamp member 5, and the clamp member 5 is moved upward without being caught on the outer circumference of the bearing 3a. Therefore, the warp beam 4 is pulled out from above the mounting recess 2a, and following this operation of taking out the empty warp beam 4, the bar 7 is moved downward from the standby position shown in FIG. 1 while contacting the warp beam axis 3. As shown in FIG. 2, when the joining position of the clamp member 5 and the bearing 3a reaches the uppermost end of the bearing 3a, the bar 7 contacts the position regulating portion 5a without contacting the guide groove 2b. Then, when the empty warp beam 4 is further pulled out from FIG. 2, the clamp member 5 moves downward slightly, and as shown in FIG.
It touches a predetermined position on the guide groove 2b while being pressed against the guide groove 2b. As a result, the clamp member 5 is maintained in a position in which the bearing 3a can be released in the direction in which the empty warp beam 4 is taken out.

After taking out the empty warp beam 4, place a full warp beam (not shown) on the tip side of the bracket 2 and roll it along the guide groove 2b toward the mounting recess 2a, and the bearing will be removed as shown in FIG. The upper outer periphery side of 3a abuts against the lower edge of the clamp member 5. As a result, the pushing force of the full warp beam acts on the clamp member 5 through the upper outer periphery of the bearing 3a, and the clamp member 5 moves upward slightly. By further pushing the full warp beam, the warp beam shaft 3 comes into contact with the bar 7, and the bar 7 moves upward while the clamp member 5 moves downward. When the full warp beam is fitted onto the mounting recess 2a, the clamp member 5 comes into contact with the guide groove 2b as shown in FIG. 1, and the bar 7 returns to the standby position.

As described above, in the operation process of taking out and installing the warp beam, the rotation operation of the clamp member 5 and the maintenance of the released position are automatically obtained from the rolling operation of the warp beam on the bracket 2.
Therefore, the user can concentrate only on moving the warp beam, and the work of taking out and installing the warp beam is smooth and safe.

Incidentally, even if the tension spring 8 is omitted in this embodiment, the bar 7 can move downward due to its own weight following the action of taking out the warp beam, and can maintain the released posture of the clamp member 5.

The present invention is, of course, not limited to the above-mentioned embodiments. For example, as shown in FIGS. 4 and 5, a torsion spring 10 is interposed between the clamp member 9 and the bracket 2, and It is also possible to provide a configuration in which the locking end 10a of the torsion spring 10 on the clamping member 9 side extends as shown in the figure. In this embodiment as well, as the warp beam is taken out and installed, that is, the bearing 3a moves in and out, the latching end 10a contacts and follows the warp beam axis 3, resulting in the standby position shown in FIG. 4 and the standby position shown in FIG. The clamp member 9 is moved between the positions where the released position is maintained.

Effects of the Invention As detailed above, according to the warp beam support device of the present invention, the rotation operation of the clamp member and the maintenance of the released posture are automatically obtained from the rolling operation of the warp beam on the warp beam mounting member. This provides an excellent effect in that the warp beam removal and installation work can be carried out smoothly and safely.
