Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] The present invention relates to a press roll device for a drum machine that guides and presses warp threads to be wound onto the drum of the drum machine.

Conventionally, the drum of this type of drum machine generally consists of a cylindrical part with a circumference of about 210 Dxya or more and a tapered part, and the reed and main inner roll are attached to the drum in order to wind the warp threads around the drum. By moving laterally parallel to the axis and taper part,
Although winding is performed sequentially so that the cross-sectional shape of the yarn layer wound on the drum becomes a parallelogram, the warp yarns are extremely susceptible to weather conditions such as temperature and humidity, and the yarn layer is wound parallel to each other. It is difficult to make it into a quadrilateral shape, and the yarn layer of the next section is layered on top of the yarn layer of the previous section warping.
Even if the yarn layer for warping the front section was formed into a parallelogram, it had the disadvantage of collapsing.

The present invention makes it possible to wind the warp threads uniformly in the same condition,
In addition to improving unwinding in the next process, the outer diameter of the warp threads wound around the drum is approximately constant, so that the rotation of the drum and the tension of the unwinding threads are uniform when unwinding from multiple sections. To provide a press roll device for a drum machine, which simplifies the device for post-processing, and also reduces the weight of the separate rake that divides each section, and simplifies the mechanism and fixing means for its movement. It is something.

In a drum machine equipped with a mounting base on which a reed is movably mounted parallel to the taper section, a guide press roll that guides the warp threads to the bobbin winding surface corresponding to the width of each section is moved at a predetermined ratio in accordance with the rotation of the drum. The movement of the guide press roll is controlled so that the winding starting end portion, which is the pressing position, is always the same.

The base press roll 21 is controlled to move at a predetermined ratio in accordance with the rotation of the drum, and the winding starting end portion A, which is the pressing position, is always the same, so the base press roll 21 presses the bobbin surface. This completely eliminates the influence of weather conditions such as temperature and humidity, allowing the yarn layer to form a uniform parallelogram, and even when the yarn diameter changes, the winding start point remains constant. By pressing A, the warp threads W can be wound uniformly in the same shape, and therefore the warp threads W can be unwinded in the next step without any problems, and the warp threads W can be wound around the drum 7. The finished outer dimensions of the warp yarns W can be made approximately constant, so when the warp yarns W are unwinded in parallel from a double-bedded section, the rotation and unwinding of the drums 7 can be prevented by pulling in heavy equipment. Since the tension of the yarn can be made uniform, the equipment for post-processing can be simplified, and since it is a simple mechanism, existing equipment can be used effectively by just making some improvements8.

Further, a drum 7 constituted by a cylindrical portion 5 is rotatably provided, a lateral moving table 14 is provided so as to be movable in the axial direction of the drum 7, and a mounting table 20 for mounting a reed 28 on the lateral moving table 14 is provided.

Since the movement of the guide press roll 21 is controlled so as to always maintain the same value, in addition to the same effect as described above, the large diameter of the cylindrical portion 5 allows the yarn to be

Since the thickness of the layer is small, the load applied to the separators 35, 35a... that divide each section is also small,
The weight of the separators 35, 35a, etc. can be reduced, and the structure and fixing means for movement in the direction of the drum axis can also be made into parts, which has great practical effects. .
