Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for applying a release agent to a concrete form plate material.

[0002]

2. Description of the Related Art There is a plate member for a formwork in which a reinforcing frame is attached to the back surface of a thick plywood plate, and this plate member is 3 × 6.
Although it has a constant size such as a scale and is repeatedly used, the work of applying the release agent before use has relied on human hands. Naturally, there is a limit to the efficiency of this type of work, but the number of people who are engaged in work due to oil stains and heavy work has decreased.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and it is an object of the present invention to continuously and automatically perform a work of applying a release agent to a plate material for a mold. Is to be able to.

Incidentally, unlike the iron plate, the plywood used in the plate material for the formwork is manufactured according to the JIS standard, but the difference in stock time after production, the stock situation, the plywood, etc. Difference in quality, quantity, and water content of glue during production,
The shape is clearly different one by one, depending on the position of the pillows when they were stacked.

Therefore, when observing the stacked state,
In some cases, a warp or a warp and a deformation such as a corrugation are observed. As a result, there is a case where a misfeed occurs in which two sheets should be fed one by one.

[0006] Therefore, another object of the present invention is to establish means for accurately feeding the form plate materials one by one.

[0007]

In order to solve the above-mentioned problems, the present invention provides an apparatus for applying a mold release agent to a mold plate material by stacking a large number of mold plate materials 1 up to a carry-in position 2 one by one. A loader unit 3 for causing the mold plate member 1 to move toward the coating mechanism 6 following the carry-in position 2, and a mold plate member positioning unit 4 that defines a position and a posture in which the mold plate member 1 can be transferred.

[0021]

In the releasing agent coating device having the above-described structure, when the mold plate material carried into the loader unit 3 is lifted, the highest position
When the mold plate material 1-1 of No. 1 reaches the loading position 2 , the loader
The part 3 is stopped, but at this time, a signal is emitted by the detection switch 12 , and the tracer 17 of the feeding means 5 elastically contacts the upper surface of the uppermost plate member 1-1, and the contact piece 16 is contacted. Comes into contact with the upper surface of the rear end e of the uppermost form plate material 1-1, and at the same time, the locking piece 15 locks at the rear end e, and when the feeding cylinder device 20 causes the feeding means 5 to start the transfer. Rolling wheel 1 on the upper surface of the second plate material 1-2 for formwork
8 are in contact with each other to transfer the form plate material 1-1.

The form plate material may have various forms as described above, but the upper surface of the uppermost one 1-1 is pressed by the tracer 17 and the contact piece 16, and the second one Since the item 1-2 is pressed by the wheel 18, only the uppermost one is engaged with the locking piece 15, and only one is accurately fed.

When the mold plate material 1 fed as described above enters the coating mechanism 6, the pressing roller 36 is pushed up by the tip of the molding mechanism 6 and passes between it and the coating roller 8 while being transported by the multiple feed rollers 32. To do. Since the liquid release agent is adhered to the entire surface of the application roller 8, the release agent is applied to the upper surface of the mold plate material 1 in a transferred state.

The mold plate materials 1 that have passed through the coating mechanism 6 are stacked on the unloader 10 at the unloading position. In the meantime, the next plate material for the formwork is pushed up to the uppermost position on the side of the loader unit 3, and the unloader unit 10 goes down by one sheet to prepare for the feeding and coating of the next formwork plate material. .

[0025]

Since the present invention is constructed and operates as described above, a large number of stacked form plate members 1
Has been used, it may be warped, warped or corrugated in various ways.
And even though, in together to be able to transfer one by one accurately by means 5 sends these from the loader unit 3, At a coating mechanism 6 is coated with a release agent by a coating roller 8
Since it is possible to perform stacking again in the unloader unit 10, there is an effect that the work of applying the release agent to the plate material for the frame and stocking it can be automatically performed.

In particular, like the feeding means 5 of the present invention, the contact piece 16 and the tracer 17 which are in pressure contact with the upper surface of the uppermost plate member 1-1 and the tracer 17 and the uppermost plate member 1-1 are locked. Piece 15
When the rolling wheels 18 that are pressed against the second form plate material 1-2 are provided in a locked state, even if there is a morphological difference in the form plate material 1, they can be accurately fed one by one. There is an effect that the automatic application effect can be executed more reliably.
