Abstract

PURPOSE:To properly arrange plate materials with high accuracy without swelling a sheet by disposing heating discs inclined downward on the forward end of a cylinder device, thereby to weld a sheet and press a plate material in a device for correcting a difference in loading position of a plate material having the upper surface coated with a sheet. CONSTITUTION:With a heating disc 11 of a reference air cylinder 8 projected, a new plate material 1 is loaded on the plate material on a table lifter 7. After that, a push cylinder 9 is expanded to press the upper edge of the end surface of the plate material 1 from above a sheet 2 with the heating disc 11, so that a projected portion of the sheet is melt to be welded to the plate material 1. When the plate material 1 is pressed until it contacts the heating disc 10 of the reference cylinder, the plate material 1 is located at a position of the heating disc 10. At the reference heating disc 10, a projected portion of the sheet 2 is welded to prevent a swelling. On the completion of correcting a difference in position, the table lifter 7 is lowered by the thickness of the plate material 1, and the air cylinder 9 is contracted to repeat loading the plate material 1 and correcting a difference in position.

Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a loading deviation Il', ilE device for completely correcting the deviation of a board-side loaded object whose upper surface is covered with a packing sheet.

[Background technology]

Conventionally, when a board I such as decorative plywood processed in a factory is transported to a site or other process, it is covered with a packing sheet to prevent damage. This loading is carried out using an automatic loading machine, but since deviations occur, a loading deviation correcting device shown in FIG. 1 is used. In the figure, the surface of the sheet 2 of the packing flJ, which slightly protrudes from the periphery of the sheet 2, is covered with dust by the plate material placed on the l1jffl. Board material 1
It is loaded on a tri table lifter (not shown).

A guide member 3 is provided opposite to one side of the upper edge of the loaded body, and a cylinder device 5 having a push piece 4 that moves forward and backward along the guide member 3 is installed on the guide member 3. The guide member 3 d is mounted on a fixed base (not shown) via a support member 6 . The pushing piece 4 presses only the plate material j without pushing the sheet 3, and presses the end portion 7iii1 into the lower plate U1.

However, the plate material 1 has various thicknesses, and in the case of a thin plate material 1, the sheet 2 is pressed with the pusher piece 4 to create a bulge 221 as shown in Fig. 2, making it difficult to position the sheet accurately. become unable. As a result, if the edges of the board 1 become uneven, the edge of the board AJ scratches the surface of the board 10 above it by the M (star) of the board 1 loaded in large numbers on the sled.
This may result in defective products. Same thickness V) Board 1
Even when handling the sheet 2 with a sharp edge, the protruding shape R of the sheet 2 is not constant, resulting in the problem of unevenness due to the above-mentioned bulge 2a.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide an on-board misalignment correction device that can align plate materials covered with sheets with high precision without causing bulges or the like in the sheets.

[Disclosure of the invention]

In the stacking misalignment correcting device C of the present invention, a thermal mirror is installed at the tip of a cylinder device with a downward inclination in several examples, so as to push the plate material while welding the sheets.

Embodiment An embodiment of the present invention is shown in FIG. 3I/c. In the figure,
Reference numeral 7 denotes a table lifter, on which a large number of plates AI are loaded, covering the entire upper surface of the packaging sheet 2.

The sheet 2t/'i is large enough to slightly protrude around the entire circumference of the ladle 1, and is made of a vinyl chloride sheet or the like. A loading machine (not shown) is provided for dynamically loading the plates 1 one by one onto the table lifter 7. A pair of air cylinders 8 and 9 are provided facing each other at a predetermined height position above both sides of the table lifter 7, and heat cylinders 1110 and 1 are installed at the tips of the piston ronds of these air cylinders 8 and 9 so as to be inclined downward. It is being Heat mirror 10. It has a built-in electric heater, and the surface temperature is a constant temperature VcIIJ depending on the thickness of the sheet 2, the material of the plate 1, etc.
Controlled. For example, if the board j is helical, /d2
About 00℃uf.

If the temperature is oak, the temperature is set at about 250°C.

The ring bodies of the air cylinders 8 and 9 are fixed to a fixed base (not shown) on the floor. One air cylinder is for the reference position of 8, and the other air cylinder is for pushing 9. something is being used.

motion Eight reference air cylinders and a heat mirror 10 are taken out in advance.

In this state, the stacked plate 1 is loaded onto the plate 1 of the table lifter 7 by the loading machine. At this time, the plate material j is loaded with a slight distance from the thermal mirror j0 of the air cylinder 8 on the reference side toward the pushing air cylinder 9 side. Thereafter, the pushing air cylinder 9 is extended and the upper edge of the end surface of the plate material 1 is pushed by the heat mirror 11 from above the sheet 2. At this time, the protruding portion of the sheet 2 (l) is melted by the heat mirror II and welded to the plate material 1. Therefore, the bulge 2a as shown in Fig. 2 does not occur in the sheet 2. When it is pushed until it touches the mirror IO, the air cylinder 8 on the reference side has a greater pressing force, so the plate 1 stops +L and is positioned at the position of the thermal mirror 10 at this time. Even if the mirror jO is 1..., the protruding part of the sheet 2 will be welded, and the bulge will be prevented.When the positional deviation correction is completed in this way,
The table lifter 7 (il-plate material) is lowered by j gits, the pushing air cylinder 9 is shortened, and the loading and positional deviation correction of the plate materials 1 are repeated.

In this way, the positioning of the plate material can be performed without causing any bulge in the sheet 2, and the bottom portions can be aligned with high precision. Therefore 5. This prevents damage to the surface of the plate 1 due to misalignment of the plate 1 below. Also, the positioning is always accurate/ζ, do you have to redo the + work? There is no need to do this, improving work efficiency and safety. Note 1
The position can be corrected by using only the pushing air cylinder 9 and the heat mirror 1, but in this case, the sheet 2 of the plate J below causes a shift Q in the plate 1, which may cause it to move past due to inertia. However, heat mirrors from both sides like this] 0.II
If you press K with K, there will be no problem with the 1st row.

Positioning can be performed with even higher precision. The thermal mirror 10 on the reference side may be fixed, but if it is attached to the air cylinder 8 several times, it may cause unreasonable pressure and breakage (L!
This can prevent damage to the device and damage to the plate material 1 in the event of malfunction or the like.

〔Effect of the invention〕

The stacking t1 correction device d of the present invention has the effect of being able to align the four sheets of board material covered with notebooks with high precision without causing any bulges.
