Description

[Detailed description of the invention] Regarding machines that can be corrected.

Conventionally, heating means are used to heat materials to a correct temperature.

A thin plate straightening machine equipped with a plurality of sets of straightening rollers to remove distortion by compressing a heated material is known from Japanese Patent Publication No. 37-2787. If the work can be done quickly and without the need for manpower, and if the correction of twists and warps in the material can be completed during transportation, it will save labor and increase efficiency. Although this machine had a remarkable effect, in a machine like this one, in which multiple sets of correction rollers are lined up on the same plane, the material, which has become plastic due to heating, can be simply compressed and twisted or warped. Since it is not possible to actively apply a force to correct the curvature, the correction effect is poor, and even in objects such as veneers, twists and warps cannot be removed with a single operation.

The present invention was made to eliminate this drawback.
It is an object of the present invention to provide a machine that can completely correct the twist and warp of a material in a single operation by adjusting the relative positions of a plurality of sets of correction ρ-ra so as to enhance the strain relief effect.

Next, an example of the implementation of the thin plate repairing machine according to the present invention will be described below with reference to the drawings.

1 in the figure is a frame, and a base 2 is installed on the top of the frame.
A suspension frame 3 is disposed above the suspension frame 3, and the suspension frame 3 is supported by columns 4, 4, and supported by an elevating body 6 engaged with an elevating means 5 such as a feed screw.

7.7 and 8.8 are heating means provided at the front and rear parts of the base 2 and hanging frame 3, and heating plates a that lightly touch the material.

To heat 8 to the correct temperature, use an electric heater or steam,
The heating plates a, a are heated as evenly as possible using a heat medium, and a heat insulating plate, b
are arranged, and the upper heating plate a, the suspension means 9 for a,
9 is equipped with springs 10 and 10 for Kuseon Yong.

11.11 is several sets of correction rollers provided between the heating means 7, 7 and 8, 80, both ends of the second correction rollers 11, 11 are supported by support means 12, 12, 13.
Either one of the support means 12.12 as shown in the drawing or both support means 12.12 and 13. as shown in FIG. 4 of the drawing.
13 is engaged with means 14.14 for adjusting the elevation, and by operating this adjusting means 14.14, the relative positions of the several sets of correction rollers 11, 11 can be freely adjusted. 15.15 is a chain wheel that drives the correction rollers 11.11, and is connected to the correction rollers 11, 11 by universal joints 16, 16 so that power is transmitted regardless of the inclination of the correction rollers 11.11. Rotation transmission from the chain wheels 15, 15 to the correction wheels 11, 11 can be achieved by connecting two universal joints 16, 16 with a spline shaft 17 as shown in FIG. Correction tilted from 15 degrees 15--rotation transmission to the roller 11 is performed more smoothly. I
JI, 18 and 19.19 are guide rollers provided on the front and rear sides of the correction roller 11.11, respectively.

By cooperating with the relay piece 20.21 provided between the heating means 7 and 8, the correction roller 11.
The feeding of material from the modified p-ra 11.11 to the heating means 8.8 is carried out smoothly and without interference. Reference numeral 22 is a material feeding p-ra provided in front of the heating means 7, 7, which pinches the material supplied to the supply plate 0 and feeds it to the heating means 7, 7.

24.24 is a material pull-out roller provided on the rear side of the heating means 8, 8, and sends out the material that has passed between the heating means 8.8 to the extraction plate 22; In the air pipe provided between the pull-out roller 24.24.

Air is blown onto the surface of the material that has been corrected to blow away the steam to prevent condensation on the surface of the board, making handling dirty, and preventing the removal board from sticking. n is a motor that drives each roller, and its rotation is reduced by a reduction gear island to drive the pull-out rollers 24, 24, . Guide rollers 18, 18, correction rollers 11, 11, guide rollers 19, 19, feeding p
- The rotation is transmitted to the rollers 22, 22, and each roller is rotated in synchronization.

In addition, in this correction machine, since the heating means 7.7 and 8.8 and the correction rollers 11, 11 are provided separately, the correction roller 1
As for 1 and 11, a rubber ruler was used to adjust the clamping force of the material using the cushioning properties of rubber, but the modification - Rule 1
1. If a part of n is heated by a heating means such as a heater or a heat medium.

The heating means and the correction p-ra are integrated, but since rubber rollers cannot be used in this case, iron rollers are used, and the material clamping force is adjusted by elastic pressure from the spring of the support means. shall be.

Also, some materials can chemically react with iron and cause discoloration or stains, so with this in mind, all parts that come into contact with the materials are made of stainless steel.

Or apply chrome plating etc.

Furthermore, this correction iE (3%) adjusts the relative position of each correction p-ra II, 11 by adjusting up and down one of the support means 12, 1; l! and 13.13 of the correction roller 11.11. Is this carried out in a one-sided tilted state as shown in Figure 3 of the drawings?

Alternatively, by raising and lowering both the support means 12.12 and 13.13, the relative position can be adjusted in both inclined states, although this is not shown in the drawings.

Next, the operation of the thin plate repairing machine according to the present invention will be explained.

When the tip of the material to be corrected is laid flat as shown in Figure 5 of the drawing, and the end is twisted so that it is downward to the right, several sets of correction rollers 11 are used as shown in Fig. 6 of the drawing. ,1
Supporting means 1 is attached to every other set of supporting means 1 so that the right end is deviated upward.
Adjusted according to 3.13.

When a material is supplied to the supply plate 23 and its tip is inserted between the feed rollers 22 and 22, the material is transferred to the feed roller 22.
, 22, it is sent between the heating means 7, 7,
When heated by the heating means 7, 7 to a suitable temperature for correction, the correction roller 11 passes through the relay piece and the guide rollers 18, 18.
. While passing through, the twist is corrected and it advances between the heating means 8, 8 on the rear side, and after being heated by the heating means 8, 8, it passes between the air pipes 25, 25 and is air-dried, so that it is not twisted. It is stabilized as a flat plate, taken out onto the take-out plate 3 by the draw-out rollers 24, and then discharged to the outside.

In addition, if the material is laid flat with its leading edge as shown in Figure 7 of the drawing, but the rear end is twisted so that it is on the lower left, several sets of correction rollers 11.11 are used as shown in Figure 8 of the drawing. If every other set of is set so that the left end is biased downward, and the material heated to an appropriate correction temperature is passed through the correction rollers 11.11, the material will receive a correction force that twists it in the opposite direction to the twist. If the twist is corrected by being pinched while pressing, or if the twist or distortion is in both directions, several sets of correction rollers 11.11 are used.
If the material is set so that it is biased either upward or downward, a straightening force is applied to the material that twists it alternately in opposite directions, relieving the complex internal stress and creating a flat surface without any twist or distortion. It is stable under certain conditions.

In addition, for this correction operation, as mentioned above, the correction roller 11,
It is preferable to not only give a relative bias to the inclination of the rollers 11, but also to alternately change the heights of the several sets of correction rollers 11, 11 to form a so-called wavy arrangement, which further promotes the above-mentioned effect. It is something.

As mentioned above, the thin plate straightening machine according to the present invention has a straightening roller that removes distortion by pinching the material heated to an appropriate temperature for straightening by a heating means, supported by a supporting means that can move up and down. This is because the relative position of the correction roller can be adjusted so as to enhance the effect of removing distortion in the material.

Unlike conventional straightening machines in which the straightening rollers are arranged in the same plane, straightening force can be actively applied to the material in the direction opposite to the twist or warp, making the straightening particularly effective. By simply passing the material through the machine once, it is possible to obtain a flat plate material from which all distortions such as twist, warpage, etc. are almost completely removed.

In particular, with this correction machine, the supporting means for the correction mouth, which was conventionally immovable, can be moved up and down, so it is possible to achieve a high performance machine that is incomparable to previous models, but at a price that is almost the same as the previous model. Moreover, the relative position adjustment of the correction roller, which changes in various ways depending on the strain state of the material, can be easily and quickly done simply by adjusting the elevation of the support means, which has a great effect on improving work efficiency. It is something to play.
