Description

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

Generally, the rolls used in flat material finishing machines have a structure not shown in FIG. 1.

That is, the roll 1 has a drum 2 at its axis, and this drum is supported by a shaft 3. A spring pad 4 is wound around the outer periphery of the drum, and a breathable felt roll is wrapped around the outer periphery of the spring pad. A cover 5 is wound around the concave curved surface 6 which is the pressure contact surface of the chess l-6.
Laundry items, such as sheets 7, are ironed between the concave curved surface 6a and the roll 1, and then dried.

Conventionally, in the roll 1 as described above, the cover 5 is attached at 50 to 60 locations at intervals of 60 to 100 mm between the innermost end (most end) 5a and the strip 4a of the spring pad 4 of the roll 1. It was fixed to the roll by tightening it to the roll with a stainless steel wire 8 (dashed line in Figure 1).

However, since the cover 5 is made of the above-mentioned material, skill is required to ensure uniform tightening force at each tightening part with the roll. Due to expansion and contraction, each tightening part may loosen unevenly, which causes the cover to twist and cause wrinkles in the laundry 7.

Furthermore, when replacing the cover 5, the above-mentioned tightening work must be performed again, which is extremely troublesome.

The purpose of this invention is to wrap a band-shaped plate around the spring pad of the roll and provide a protrusion on the outside of the plate for hooking the roll cover, thereby making it easy to attach the cover to the roll. The purpose is to make the cover easy to install and replace, and to prevent wrinkles from forming on the laundry.

Embodiments of the present invention will be described below with reference to FIGS. 2 to 6.

In FIGS. 2 and 3, a band-shaped plate-like body 10 constituting the main body of the roll cover fixture 9 has a widened part 10a and a narrowed part 10.
b are repeatedly and continuously formed, and the outlines on both sides form a substantially sinusoidal curve.

This plate-like body is made of a corrosion-resistant and springy thin metal plate such as stainless steel or phosphor bronze, and has the narrow portion 10b, making the plate-like body more flexible.

The plate-shaped body 10 is wound around the spring 4b of the spring pad 4 along the strip plate 4a, as shown in FIGS. 4-6.

In addition, a hole 11 is punched in the center of the widened part 10a of the plate-like body 10, and a hooking protrusion 12 and a misalignment prevention protrusion 13 are cut and raised in opposing positions, sandwiching each piece. be.

One protrusion 12 protrudes from the outer surface of the plate-like body 10, and the upright angle a varies depending on the material of the plate-like body, the length and width of the protrusion, etc., but the roll cover 5 is hooked onto this protrusion. In terms of strength when used as a cover, it is desirable that the angle be approximately 45 degrees or less and allow the cover to be hooked.

If this angle is greater than 45°, the protrusion 12 will have a reduced ability to open and latch the cover when pulled by the cover 5.

The other protrusion 13 projects perpendicularly from the lower surface of the plate-like body 10 in the illustrated example, and is inserted into the spring 4b of the spring pad 4 (Fig. 6), thereby changing its position in the width direction of the plate-like body. This has already been prevented.

Next, a method for fixing the roll cover 5 to a roll using the fixing device 9 of the present invention will be explained.

First, the plate-shaped body 10 is attached by fixing one end thereof to the strip 4a of the spring pad 4 (or the end surface of the drum 2), and then winding it onto the spring 4b along the strip.

When the spring pad has been wound from one side to the other, the other end is fixed by appropriate means (Figures 4 and 5).

At this time, the hooking protrusion 12 is positioned outside the plate-like body 10.

After attaching the fixture 9 in this way, the hooking protrusion 1
2, the cover 5 is sequentially pressed backward from the tip 5a, the cover is wound around the roll a predetermined number of times, and the other end is fixed by appropriate means.

At this time, the entire surface of the cover 5 that comes into contact with the plate-shaped body 10 is hooked by the projections 12 and securely fixed to the outer periphery of the spring pad 4.

Therefore, during the operation of the flat goods finishing machine, the same tensile force is always applied to the fixed part between the cover 5 and the roll 1, so that the cover partially expands and contracts and twists, causing wrinkles in the laundry. There is no.

Further, since a hole 11 is formed in the fixture 9, this hole functions as a ventilation hole when the plate-shaped body 10 is disposed in close contact with the cover 5, as shown in FIG. Breathable for laundry.

In addition, to replace the cover 5, simply unscrew one end of the cover and remove it from the protrusion 12, and it can be easily removed from the roll 1. Then, install a new cover according to the procedure described above and replace it. Finish.

When winding the plate-shaped body 10, it is not necessary that the widened portion 10a fits into the adjacent narrowed portion 10b as shown in FIG.

Furthermore, since the plate-like body 10 has the narrow portion 10b, it is flexible, and when this plate-like body is manufactured by punching from a steel plate, there is no waste of material, which is advantageous in terms of cost. be.

Furthermore, it is desirable that the width of the widened portion 10a of the plate-shaped body be larger than the diameter of the upper surface of the spring 4b in order to prevent the widened portion from digging into the spring.

Further, the projection 13 for preventing positional deviation does not necessarily need to be provided.

The position of the band plate 4a of the spring pad 4 is fixed by using the roll to some extent, but when the plate-like body 10 is used for such a used roller, it is preferable that the plate-like body 10 has projections 13.

As explained above, according to the present invention, the roll cover is attached by being hooked on the hooking protrusion of the plate-shaped body, so it is easy to install, and it is also easy to replace. The cover can be securely fixed to the roll, and furthermore, the cover does not expand or contract unevenly during rotation of the roll and does not adversely affect the laundry.
