Description

[Detailed Description of the Invention] The present invention relates to a fixing device for a roll cover in a flat article finishing machine for drying and finishing flat articles such as sheets, wrappers, tablecloths, napkins, and Yukata.

Conventionally, as shown in FIG. 1, the structure of a dry fish finishing machine is generally such that a roll 1 constituting the main part is supported by a shaft 2, and this roll is supported by a drum 3 and a spring pad 4 attached to the outer periphery of the drum. and a breathable felt cover 5 wound around the outer periphery of the spring pad, which is also placed close to or in pressure contact with a concave curved surface 6a which is a pressure contact surface of the chest 6.

Laundry items, such as sheets 7, are ironed between the concave curved surface 6a and the roll 1, and then dried.

In such a dried fish finishing machine, conventionally, the cover 5 is attached to the roll by using stainless steel wires 8 at 50 to 60 points at intervals of 60 to 100J7EI1 between the innermost end 5a and the strip of the spring pad 4 of the roll 1. It was fixed to the roll by tightening it.

However, since the cover 5 is made of the material mentioned above, it requires skill to ensure uniform tightening force at each tightening part with the roll, and it is difficult to remove the cover while the flat goods finishing machine is operating. Due to expansion and contraction, each tightening part may loosen unevenly, which causes the cover to twist and cause wrinkles in the laundry 7.

Or, the expensive cover will have to be replaced even though the cover still has the durability.

Furthermore, when replacing the cover 5, it is necessary to cut or unravel the wire of the tightening portion and then perform the tightening operation again to attach a new cover, which is extremely troublesome.

The present invention was developed in view of the above problems, and by providing a protrusion for hooking the cover on the plate-shaped body fixed to the roll, the cover can be connected to the roll with uniform tightening force, and the cover can be fixed to the roll with a uniform tightening force. An object of the present invention is to provide a fixing device for a roll cover in a dry fish finishing machine that can be easily replaced.

Hereinafter, one embodiment of the present invention will be described based on the drawings from FIG. 2 onwards.

In FIGS. 2 to 4, a sheet roll cover fixing device 10 according to the present invention has a wire insertion hole 10 on one opposing side of a plate-shaped body 10a as a fixing part to the roll of a flat material finishing machine.
b, 10b, . . . are provided, and rising pieces 10c, 10c, .

To explain in more detail, the plate-like body 10a has a thickness of, for example, 0.
It may be made of a corrosion-resistant metal such as stainless steel or phosphor bronze with a thickness of about 4 to 0.5 m++, and its length should match the length of the roll, and the depth L1 should be about 50 to 100 mm, and the length should be about 50 to 100 mm, and the length should be about 50 to 100 mm. Both have an arcuate cross section (if the roll has a large diameter, it can be used as a flat plate)
It was formed in

A suitable number of wire insertion holes 10b, 10b, . . . are formed in parallel at regular intervals.

The rising pieces 10c, 10c, .
(Fig. 4) varies depending on the material of the plate-shaped body 10a, the length and width of the rising piece, etc., but from the viewpoint of strength when used with the cover hooked on the rising piece, as described later. , it is desirable that the angle is less than about 45 degrees and that the cover can be hooked.

As a result, in the case of a large angle, the rising piece 10c.

10c, . . . open when pulled by the cover, reducing the ability to latch the cover.

Further, at the lower front of the tip of each rising piece 10c in the plate-like body 10a, there is a groove 10d cut and raised on the rising piece 10c.
(Fig. 3) A ventilation hole 10e is provided.

Attachment of the fixture 10 to the roll 1 will be explained.

First, the eyelet 11 (Fig. 6) is attached to each wire insertion hole 10b, and then, as shown in Figs. 5 and 7, the rotation direction (arrow direction) of the roll 1 (drum 3) is The pieces 10c, 10c, . . . are placed on the spring pad 4 of the roll so that their upright directions are opposite to each other.

As shown in FIG. 6, each wire insertion hole 10b
and a band-shaped iron plate 4a wound spirally around the drum 3.
A plurality of ventilation holes 4b provided in the.

4b, . . ., stainless steel wires 12.12. The fixing of the fixture 10 to the roll 1 is completed by passing the fixing device 10 through the roll 1 and connecting both ends thereof with the crimping sleeves 13, 13....

In this case, since both the fixture 10 and the iron plate 4a have rigidity, all the wires 12, 12, . . . can be tightened with the same tension.

In order to attach the cover 5 to the fixture 10 attached to the roll 1 in this way, rise 10c.

10c, . . . as shown in FIG. 7, one end 5a of the cover 5 is hooked and pressed, and the cover is wound around the roll 1 a required number of times in this state.

As mentioned above, the cover 5 has wires 12, 12,...
Since it is hooked to the fixture 10 fixed to the roll 1 with the same tension by , so that the cover does not partially expand or contract, causing twists and wrinkles in the laundry.

Further, since the fixing device 10 is formed with ventilation holes 10e, 10e, . . . , the cover or the laundry can be ventilated in the same manner as in the conventional device not provided with the fixing device.

In addition, the wires 12, 12... are inserted through the wire insertion holes 10b, 10b,... of the fixture 10 through the eyelets 11, so even if the flat material finishing machine is operated for a long period of time, the wires 12 is difficult to cut.

Then, the cover 5 is attached to the rising piece IQcwlOcw of the fixture 10 by reversing the roll and pulling the cover.
It can be easily removed from the roll 1 by simply removing it from the cover, and a new cover can also be easily fixed to the roll by the procedure described above.

As explained above, the present invention has a structure in which a protrusion for hooking onto the cover is provided on the plate-like body, so once the cover is attached to the roll, it is possible to fix the cover to the roll again or replace the cover. This is extremely simple and easy, and no skill is required to replace the cover.

Furthermore, since the cover does not expand or contract unevenly due to the operation of the flat article finishing machine, it does not adversely affect the laundry, which is an excellent practical effect.
