Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spring plate that elastically supports a roll cover from the back side of a finishing machine for drying and finishing dried laundry such as sheets, wrappers, tablecloths, and napkins.

Conventionally, the rolls of finishing machines for finishing flat laundry have been wrapped with a roll cover made of felt, for example, and this roll cover is elastically supported from the back side by a spring plate. (German Patent No. 120)
No. 8284). The spring plate in this example has a seven-oak shape with three spring pieces, and each spring piece has a ventilation hole and a claw slightly spaced apart from each other at the tip of each spring piece, and the claw stands up from the top surface of the spring piece. It is. These spring plates are attached to the outer periphery of the roll in a continuous overlapping manner, and the claws are used to hook the back surface of the roll cover to elastically support the roll cover.

Another example of a spring plate is shown in Figure 1.2.

This spring plate 1 is attached by having 94 spring pieces 3 extending to the left from a base 2, and circular notch holes 5 are punched out at the tips of the spring pieces as shown in FIG. Two cut lines 5a + 5a are made parallel to the inner circumferential surface of the spring plate toward the leading edge of the spring piece, and the claws 6 formed by these cut lines are cut and raised before plating the spring plate. be. The installation is carried out by providing a stopper piece 2a on the right side of the base 2 and standing this stopper piece vertically. The spring plate 1 is manufactured by punching out an iron strip plate and attaching the spring plate 1 to the base 2 and the spring piece 3. After forming the notch hole 5, a cut line 5a, Sai is inserted through the notch hole, and a claw 6 metal is cut and raised, and then the band plate is cut into predetermined dimensions to completely separate the spring plate, and immediately after separation; After the stopper pieces of the plate are erected vertically, each separated spring plate is plated. The plated spring plates 1 are sequentially assembled into a strip-shaped support plate in an overlapping state. That is, as shown in Figure 1.2, K
, to install each spring plate 1, the base @ is first assembled on the band-shaped support plate 19.In order to install the spring plates, line them up on the right side of the base, and first attach them to the right 4 part of A 44 between each spring piece 3. The stopper pieces of the assembled spring plates are positioned, and both ends of the base are supported by bending both end sides 19a, 19a of the support plate.

However, this latter example has the drawback of F. In other words, in this example, from the punching of the strip? , ] This means that the entire process of completing the spring plate through one process cannot be performed continuously and automatically.

This is because during plating, the strip is cut into predetermined dimensions and the spring plate is damaged, so continuity between the strip punching process and the plating process is important. This is because the continuity is lost when the spring plate is separated by the plating process, and when the spring plate is assembled after the plating process, the front and back sides and orientation of the spring plate are checked and set for assembly. (In order to automate this process, the founder of this book tried to do a patching process without cutting the strips, take the strips across the street, store them on a rocky shore, and then cut the nails. However,
In this case, both end faces of the claw were not plated, and therefore corrosion occurred on the entire end face within a short period of time, resulting in the claw becoming chipped. In order to prevent the nails from corroding, we tried plating the entire mold by cutting and raising the nails in advance, but since the nails were cut and raised in advance, the nails could get into the grooves of the spring pieces or cause the nails to cross each other. This caused serious problems in winding and rewinding during assembly, making it impossible to put it into practical use.

The former example also has the above drawbacks, and it has been difficult to automate the continuous manufacturing process with the conventional structure of the spring plates on each side.

In addition, according to the latter example, a step of raising the stopper piece is required, and a step of positioning this stopper piece in the groove between the spring pieces of the previously assembled spring plate is required during assembly, which increases the number of steps. As a result, manufacturing and assembly were time-consuming.

An object of the present invention is to provide a spring plate in which the processes from punching out a strip, plating, and assembly can be performed continuously and automatically. The spring plate of the present invention is mounted on one side of an elastic thin metal plate made of iron or the like, and a plurality of spring pieces are arranged in parallel with a predetermined gap between the base and the other side. A notch hole is punched out at the tip of each spring piece, and a pawl is provided protruding from the inner surface of the notch hole, and the gap between the outer peripheral surface of the pawl and the inner peripheral surface of the notch hole is filled with plating liquid It is large enough to accommodate. Then, the strip is punched out to form a mounting base, a spring piece, a cutout hole, and a pawl, and then the strip is plated and wound on a winder. The wound strip is then set in the material feeder of the assembling machine, and the claws of the strip are raised at a predetermined angle. The spring plate of the present invention is mounted by horizontally protruding anti-slip pieces from the side end faces opposite to the spring pieces at both ends of the plate. When the pre-assembled spring plate is attached to the support plate, the anti-slip protrusion is arranged in contact with the side end surface of the base to prevent the spring plate from shifting during use.

An embodiment of the present invention will be described below with reference to FIGS. 4 to 11.

In Fig. 4.5, the spring plate 11 is made of an elastic plate made of metal such as iron that corrodes, and the base 12 is left attached on the - side (right side), and this attachment is carried out from the base to the other side with a plurality of approximately Spring pieces 13 having the same shape are extended in parallel with a predetermined gap 14 in between. At the tip of each spring piece 13, there is a fourth.
As shown in Figure 6.7, a notch hole 15 is formed by punching. On the inner surface of one side of each notch hole, a tongue-like claw 16 is provided horizontally protruding toward the base 12, and the internal shape of the notch hole is in the shape of an opening. In this nail, the seventh
As shown in the figure, the outer circumferential surface 16a and the inner circumferential surface 1 of the notch hole 15 are
The gap 17 with respect to 5a is wide enough to allow the plating solution to sufficiently enter the gap and plate the outer and inner circumferential surfaces. When assembling the spring plate 11, the pawl 16 is used by being raised upward at a predetermined angle as shown by the chain line in FIG. Furthermore, each corner of the notch hole 15 is rounded to extend the life of the mold.

Installation is done on one end surface of both ends of the base 12 (right end surface in Figure 4).
Anti-slip protrusions 12a, 12. A is mounted horizontally on the same plane as the base, and protrusions 12b and 12b are formed on the other end face at positions facing this protrusion.

12c is a circular ventilation hole provided in the base 12.

Next, the manufacturing and assembly of the spring plate will be explained.

The strip is punched out and attached to the base 12 as shown in Figure 8.
．． Spring piece 13. A notch hole 15 and a pawl 16 are provided to form a strip plate 18 having a continuous spring plate. The notch hole 15 and the claw 16 are punched out at the same time as the base portion 12 and the spring piece 13 are punched out for attachment.

After punching, the strip 18 is immersed in a plating solution for plating, and then the strip is sequentially wound up by nine winders. During the plating process, the outer peripheral surface 16a of the fly 6 is connected to the inner peripheral surface 1 of the notch hole 15.
Since there is a sufficient gap 17 from 5a, the inner circumferential surface of the notch hole and the outer circumferential surface of the claw are also sufficiently plated. Also, the strip plate 18
When winding up the tape, the fly 6 is on the same plane as the strip plate 18 and has not yet been raised, so there is no problem in the winding operation. Thereafter, the strip rolled up by the winding machine is attached to the material feeding tray of the automatic assembly machine. Then, while pulling out the strip, the winter melon 16 is raised to a predetermined angle using an automatic assembly machine as shown by the chain line in FIG. As shown in FIG. 2, the continuous spring plates of the strip plate 18 are cut off from the cut line at predetermined intervals. The separated spring plate 11 is the support plate 1
It is incorporated on 9. That is, as shown in FIG. 9.10, the spring plate ii is positioned on the support plate 19, and both ends of the base 12 are fixed by bending both sides 19a of the support plate. , and the succeeding spring plate 11 is placed on top of the previously assembled spring plate, and the installation is performed as shown in FIG.
F312 is adjacent on the support plate 19, the protrusion 12b of the previously assembled spring plate, the anti-slip protrusion 1 of the spring plate of the 1zbKl wire
2a and 12a, and the subsequent spring plate is attached by bending both ends of the base and both sides 19a + 19m of the support plate. In a similar manner, the support plate 19 is moved from the right side in FIG. 9 toward the pressure, and the spring plates 11 are overlapped and incorporated into the support plate.

The spring plate 11 assembled in this way is attached to the roll by winding the support plate 19 around the roll, but the direction of the inclined force of the claw 16 of the spring plate is in the rotational direction of the roll (the first
It is necessary to match the force plane shown by the arrow in Figure 0). If the roll cover C is also rolled in the direction opposite to the direction of rotation of the roll, the back side of this roll cover will be latched by the claw 16 of the spring plate.

When this spring plate is used, a force is applied to each spring plate in a direction opposite to the direction of the arrow in FIG. 10, but as shown in FIG. 11, the anti-slip protrusion 12a is in a horizontal state.

The spring plate 12a is attached to the side end surface of the base (projection piece 12a).
b), each spring plate is prevented from shifting its position.

As explained above, according to the present invention, the handle at the tip of the spring piece is wide enough to allow the plating solution to enter between the handle and the inner peripheral surface of the notch hole, so that the spring piece can be removed from the punching of the strip. Since all processes leading to the completion of the board can be performed continuously and automatically, the manufacturing process can be made more efficient, faster, and labor-saving. For installation, a slip-prevention protrusion protrudes from the side end surface of the base on the same plane as the base, and this protrusion is placed on the support plate to prevent the spring plate from shifting by simply placing it in contact with the base. Unlike conventional stopper pieces, there is no need to stand up during manufacturing or place the spring pieces in the grooves during assembly, and the work process can be omitted.

Furthermore, the gap between the roll of the finishing machine and the iron surface varies depending on the manufacturer, and in order to correspond to the respective dimensions,
Bending angle according to each size (for example, 5-20
However, according to the present invention, since the bending process is performed by an automatic assembly machine, one manufacturing stage can be adjusted according to the user's request. can be created each time, and therefore the number of juniors and seniors can be reduced, so the practical effect is to
