Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a beam support device for a loom, and more particularly to a device that facilitates the installation of warp beams having different diameters.
[0002]
[Prior art]
As a conventional beam support apparatus, a technique disclosed in Japanese Utility Model Publication No. 1-333664 is known. This will be explained with reference to FIGS. 6A and 6B. In the figure, 1 is a floor surface on which the loom is installed, 2 is a frame of the loom, 3 is a warp beam, 4 is a warp, 5 and 6 are guides for a warp 4. A guide roller attached to the frame 2 for carrying out, 7 is a ridge, 9 is a woven fabric, and 10 is a breast beam. 11 is a shaft of the warp beam 3, 12 is a driven gear integral with the warp beam, 13 is a beam support for supporting the shaft 11 of the warp beam 3, 13a is a bearing portion thereof, 14 is a beam support 13 by a shaft 15. A shaft holder 16 that can be freely opened and closed is a bolt 16 for fixing the beam support 13 to the frame 2. The fastening means S is constituted by the bolt 13 and the bolt hole machining portion on the frame 2 side and the beam support 13 side outside the figure. . A drive gear 27 for the warp beam is disposed at a predetermined position of the frame 2 and is driven via a transmission 25 from a drive transmission mechanism interlocked with a loom main shaft (not shown). The drive gear 27 may be driven by a servo motor without being linked to the main shaft of the loom. In this case, a detection value from a warp tension sensor (not shown) provided on the support portion of the guide roller 6 is a predetermined value. A known sending device configuration is adopted in which the servo motor is driven and controlled so as to be a value.
When changing from the small-diameter warp beam 3 shown in FIG. 6A to the large-diameter warp beam 3 ′ shown in FIG. 6B, the bulk between the lower surface 2a of the frame 2 and the floor surface 1 is increased. The raising members 28 and 29 are inserted, the bolt 16 of the beam support 13 is removed, and the beam support 13 ′ is changed to a deformed beam support 13 ′. At this time, the driven gear 12 ′ integrated with the large-diameter warp beam 3 ′ has a larger diameter than the driven gear 12 integrated with the small-diameter warp beam 3, but the position of the drive gear 27 does not need to be changed.
[0003]
[Problems to be solved by the invention]
However, in the above-described prior art, it is necessary to prepare each of the deformed beam supports corresponding to the diameter of the warp beam, so that a storage space for that is required and a plurality of beam supports are prepared. Then, the cost of the device becomes high. Therefore, the applicant of the present invention provides a device in which a large number of bolt holes are provided on the frame side, and the mounting position can be changed with the same beam support by changing the mounting position of the beam support according to the diameter of the warp beam. Although it was tentatively proposed, there are a large number of mounting holes on the frame side, which requires a lot of work such as bolt hole processing, and when many bolt holes are concentrated, measures such as increasing the wall thickness to secure the frame strength are required. The cost is high.
[0004]
When changing to a warp beam with a different diameter, the present invention can handle the beam support with the same shape without changing the shape of the beam support, and further reduce the number of processing such as bolt holes on the frame side and the beam support side, An object of the present invention is to provide a beam support device capable of ensuring sufficient strength.
[0005]
[Means for Solving the Problems]
Therefore, according to the present invention, a raising member is interposed between the lower surface and the floor surface of the loom frame, and various warp beams with different diameters can be mounted by the same beam support attached to the frame via fastening means. with a, and the warp beam drive gear disposed in a predetermined position of the frame, the beam support device of a loom comprising set to mesh with a driven gear attached to various warp beam integral with said by the fastening means the fastening position for fastening the frame and the beam support and the frame and the beam support according to the diameter of the various warp beam with a plurality provided, the fastening means constituting the said fastening position and with at least a portion common to all the warp beam It is characterized by that.
