I'm starting to be able to do it.

Furthermore, the steering device 4 is composed of the steering wheels 12 and a sensor 40, and the sensor 40 utilizes the rotation of a rotary potentiometer, and as shown in FIG. Left side protrusion 1″a
A lever 42 is attached to a support bracket 41 provided on the lower surface of the
The lever 42 is pivotally mounted and protrudes, and the lever 42 is configured to swing within a certain range in a direction perpendicular to the traveling line together with a support shaft 42' provided integrally with the lever, and is rotated counterclockwise by a spring (not shown). It is biased to rotate. Then, the right side surface 42a of the lever 42 is brought into contact with the edge x' of the overlapping part Z of the two sheets X and Y to be glued, and the hook 42'' at the tip of the lever 42 is hooked on the edge x'. According to the running direction of the vehicle body 1, the lever 42 moves while being in contact with the end edge x'.
2' is equipped with a rotary potentiometer, and when the running direction of the vehicle deviates from the sheet overlapping area Z, the potentiometer rotates together with the lever 42 to determine in which direction the lever 42 has swung. The servo control is performed so as to minimize the change in the resistance value of the potentiometer, and the running direction of the steering wheel 12 is corrected by the rotation of the servo motor 17, so that the vehicle body 1 is in the seat position. It is configured to run along the overlapping part Z to the normal position.

The blow nozzle 34, the solvent nozzle 26, and the drive wheel 6 are arranged on the same running zone, so that they run over the overlapping area Z of the sheets X and Y during sheet adhesion.

The above-mentioned sheet gluing machine moves by hand to the joint of the two sheets X and Y to be bonded, and the side surface 42a of the lever 42 comes into contact with the edge x' of the superimposed upper sheet X, and the drive The tread of wheel 6 is seat X,
Rotate the handle 22 upward so that it is at the overlapping part Z of Y to raise the auxiliary wheel 23, and then
6' is placed on the sheet .

The heated air blowing device 3 inserts a hot air nozzle 34 between the sheets X and Y of the overlapping section Z and blows out hot air, thereby first blowing away dust and the like attached to the sheet surface of the overlapping section Z and cleaning it. The temperature of the sheet is raised to dry the surface and make it suitable for bonding. Next, the solvent nozzle 26 is inserted between the sheets X and Y in the same way as a hot air nozzle, and the solvent nozzle 26 passes through the impregnating agent such as felt to the sheets X and Y of the polymerized portion.
Adhesion using the solvent is performed by applying a solvent to the surface to be adhered and applying pressure with the driving wheel 6.

Also, the solvent nozzle 26 is removed together with the bracket 27, the heated air blower 3 is moved to position B, and the hot air nozzle is placed close to the drive wheel 6, and high temperature hot air is blown onto the surfaces of the sheets X and Y to be bonded. Immediately thereafter, the overlapping portion Z can be pressed by the drive wheel 6 to perform thermal bonding. In either case, the running direction is automatically adjusted by the steering device 4 as described above, so that the end edges can be accurately bonded.

As described above, the self-propelled sheet adhesive machine according to the present invention is equipped with a solvent supply device and a heating blower device on a vehicle body that is driven under pressure by a drive machine, and the solvent supply device is connected to a solvent tank on the vehicle body. The heated air blower is configured to hold the hot air nozzle attached to the heated air blower close to the running surface, so that the sheets are adhered. Hot air is first blown onto the surface to blow away dust and moisture that adheres to the surface of the sheet and impedes adhesion, creating a dry and clean surface, and after undoing the hardening caused by low temperatures of vinyl chloride sheets, etc., a solvent is applied. Since it is applied and adhered, adhesion is easy and can be done completely. In addition, since the heated air blower is supported so that it can be moved, it is also possible to move the hot air nozzle to a position close to the pressure roller and perform bonding by thermal welding, so both types of bonding can be performed with one unit. It is possible and very convenient. In addition, we installed a sensor that senses the steering wheel and the sensing edge of the sheet on the running surface and controls the running of the steering wheel, so the sheet gluing machine automatically It runs smoothly and does not come off the overlapping part. Therefore, the edge portions of the sheets can be accurately bonded, and since the machine runs automatically, the work efficiency is very high.
