Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spring pad used in a sheet roll machine.

[0002]

2. Description of the Related Art A conventional spring pad 1a shown in FIGS. 6 and 7 comprises a strip plate 2a and a coil spring 3a. A coil spring 3a is attached to the strip plate 2a in series in a wound state, and spring portions 31a standing on the strip plate are connected to each other at equal intervals.
It is continuous in. The spring pad 1a is wound around the outer peripheral surface of the roll of the sheet roll machine used for pressing and finishing wide flat laundry such as sheets and table cloths, and covers the entire outer peripheral surface of the roll.
How to wind the spring pad 1a around the roll
After fixing one end of the winding start of the spring pad to one side of the roll, spirally tighten it manually or mechanically while applying tension to the spring pad,
The other end of the winding end of the spring pad is hooked on one of tension springs having hooks on both ends, and the other end is stopped on the other side of the roll. The surface of the wound spring pad 1a is covered with a felt cover. The finishing work of the laundry is performed by pressing the roll or the bed between the bed (also called a chest) and the roll heated by supplying steam or heat medium oil (hereinafter referred to as “heat source”). Drying and finishing (wrinkle extension) are performed while pressing, and residual moisture contained in the laundry is pressed by the heated bed to be vaporized and discharged.

[0003]

The felt cover located on the spring pad 1 is pressed inward from both sides of the roll (felt cover) due to friction caused by pressure contact with the heating bed in contact with the circumference of the roll and rotation. (The width direction of the roll), and therefore the winding end end side of the spring pad below the felt cover is also drawn in the same direction, and for this reason, in the spring pad located on the surface of the roll, It will move in the length direction, especially the winding end end of the spring pad stopped by the tension spring moves toward the center, and as a result, one side of the roll on the winding end end side has no spring pad There was a problem that a part of the laundry corresponding to this one side was not fully finished. Further, as shown in FIG. 7, the outer peripheral portion of the coil spring 3a projects from the side edge of the strip plate, but the spring pad is wound tightly with time and moves in the longitudinal direction, so that the coil springs 3a are separated from each other.
As described above, there was a problem in that there was no spring at the end of winding, as a result of more movement toward the center.

An object of the present invention is to provide a spring pad which does not shift in position in the length direction and the width direction even when tension is applied to the felt cover. Another object of the present invention is to provide a spring pad which can be tightly wound around a roll and does not shift its position.

[0005]

The spring pad according to the present invention is characterized by a strip plate wound around a roll and a coil spring attached to the strip plate. It is where the protrusion and the notch are respectively formed. The notch positions and holds a coil spring in which spring portions are continuously arranged at intervals on the strip plate. In order to further prevent the spring pad from being displaced in the width direction, the protrusion is projected to the outer peripheral portion of the coil spring located in the notch or further outwardly. It is desirable to do. In order for the coil spring to be integrally attached to the strip plate, it is preferable that the inner bottom portion of the cutout be formed in an arc shape along the coil spring.

Another feature of the spring pad according to the present invention is that a hook recess for a winding machine is formed on the protrusion.

[0007]

When the pressing force in the longitudinal direction of the strip is applied to the coil spring, the position of the coil spring is held by the notch, so that the spring pad is prevented from moving in the lengthwise direction and is adjacent to the coil spring. By contacting the protrusion of the spring pad,
The movement in the width direction is blocked. The hooking recess for the winding machine formed on the protrusion is hooked on, for example, a gear of the winding machine that gives tension to the spring pad, and by attaching a brake mechanism to the winding machine, the spring pad is securely tensioned. Extends.

[0008]

Embodiments of the present invention will be described with reference to the drawings.
1 and 2, the spring pad 1 is a strip plate 2
And a coil spring 3 wound around this strip.

In the coil spring 3, a spring portion 31 rises above the strip plate 2 by a predetermined height, and each spring portion is connected by a connecting portion 32 so as to be attached to the strip plate in series.

The strip 2 is made of stainless steel or a galvanized iron plate, and is wound around the outer peripheral surface of the roll 4 (FIG. 5) to cover the entire peripheral surface.
Then, as shown in FIGS. 1 to 3, the strip 2 has two side edges,
Projections 21 are formed at equal intervals along the lengthwise direction so as to face each other in the width direction, and notches 22 are provided between the projections facing each other in the lengthwise direction. One side of the base portion is a corner portion 24 that intersects the cutout at a right angle, and the other side is continuous at an acute angle.

Each notch 22 is for holding the position of the coil spring 3 on the strip plate 2, and is a connecting portion 32.
Are hooked around the respective notches and are stopped by the presence of the corners 24. Therefore, even if a pressing force is applied to the spring portion 31 from the left-right direction in FIG. 1, the edge portion 221 of the notch 22 functions as a stopper with respect to the connecting portion 32 and the coil spring 3 is not displaced. Be blocked. The inner bottom portion 222 of the notch 22 is formed in an arc shape along the outer circumference of the spring portion 31 to ensure the prevention of movement of the coil spring 3. Further, the protrusion 21 is formed by the spring portion 3
The outer peripheral portion of the coil spring 3 located at the protrusion 21 and the notch 22 of the adjacent spring pad 1 is configured to extend to the same position as the outer peripheral portion 1 or further outward (set to the same position in the illustrated example). It is desirable that and are located substantially on the same plane (in FIG. 2, the outer peripheral portion of the coil spring is located slightly below).

As shown in FIGS. 1, 2 and 4, the protrusion 2
1 is formed with a hooking recess 211 for a winding machine, which is cut from the tip thereof. The latching recess 211 is formed by the strip 2
It is formed in a V shape so as to correspond to the shape of the gear of the winding machine that applies tension to the winding.

A circular vent hole 23 is punched between the notches 22 facing each other in the width direction in the middle portion of the strip plate 2. The ventilation hole 23 can also be used as a fixing means for fixing the strip 2 to the roll 4 (FIG. 5).

As shown in FIG. 5, the felt portion 5 covers the spring portion 31 of the coil spring 3. Further, the pressing surface 61 of the bed 6 heated by the heat source has the radius of curvature thereof matched with the radius of the outer circumference of the roll 4. The roll 4 rotates in the direction of the arrow to draw the laundry 7 into the pressing surface, and the heated bed 6 presses the laundry 7, and the laundry is sent to the opposite side.

The water remaining in the laundry turns into steam in the heated bed 6, passes through the felt cover 5, passes through the vent holes 23 of the strip 2 of the spring pad 1, and further passes through the vent holes of the roll 4. And then discharged from the center of the roll.

In order to wind the spring pad 1 on the roll 4, the winding start end of the strip 2 is fixed to one side of the roll,
The winding is performed while mechanically applying tension by using the hooking concave portion 211 of the protrusion 21 by the winding machine.

[0017]

According to the present invention, even if a pressing force in the longitudinal direction of the strip is applied to the coil spring, the position of the coil spring is held by the notch, so that the coil spring has a long length. The movement of the spring pad in the width direction is prevented, and the movement of the spring pad in the width direction is prevented by abutting the protrusions of the adjacent spring pads. Therefore, the displacement of the spring pad can be reliably prevented.

By making the projection project to the outer periphery of the coil spring located in the notch or project further outward than that, it is possible to further prevent the spring pad from shifting in the width direction. By forming the notch in an arc shape whose inner bottom portion is along the coil spring, the coil spring and the strip plate can be attached in an integrated state, and the coil spring can be effectively prevented from being displaced. it can.

Further, the hooking recess for the winding machine formed on the protrusion is hooked on, for example, a gear of the winding machine which gives tension to the spring pad, and is attached to the spring pad by the winding machine or a galvanized iron plate. Since the tension is positively applied, the spring pad is tightly wound around the roll to prevent displacement.
