Abstract

When the work is semi-automatically performed, the drive of the cylinder(610) is stopped by controlling the switch and the 2nd turning bar(700) is turned round manually, then the 1st turning bar(600) turns round by the gear train to the same direction as the 2nd turning bar(700). By applying the manual force to the 2nd turning bar(700) the movement of the 1st turning bar is made instead of depending upon the movement of the pneumatic cylinder. And by handling the various switches of the 2nd turning bar's switch box(300), the drive can be controlled the same way as the automatic operation. By the mixed performance of the semi-auto and automatic panel edge-band attachment, the steps of processing can be reduced.

The use and operation of the present invention illustrated in the accompanying drawings having such a structure are as follows.

First, before starting work; According to the size and shape of the edge band 20, the main roller (800a) and the auxiliary roller (800b) of the appropriate standard is installed. Then, the edge band 20 on the roll is correctly placed on the edge band table 630, and then the tip of the edge band 20 is placed on the main roller 800a and the auxiliary roller 800b, and the main roller 800a and the edge band holder. Pass between 900. If necessary, the edge band holder 900 is rotated by the driving of the cylinder 920 to be close to the edge of the working panel 10 so that the edge band 20 is accurately coupled to the edge of the panel 10 during operation. . Thereafter, when the power switch in the switch box 1100 is turned on, the work preparation is completed.

When you want to make the work automatic after the work preparation is completed; While the upper turntable 500 is raised, the panel 10 is seated on the lower turntable 400, and the upper turntable 500 is lowered by the cylinder 510 by a switch operation to closely contact the upper surface of the panel 10. . When the cylinder 610 is driven by a switch operation, the first pivot bar 600 is rotated by the linear movement of the cylinder rod, and the rotary end of the first pivot bar 600 approaches the edge of the panel 10. On the other hand, with the rotation of the first rotation bar 600, the second rotation bar 700 meshed with the gear train 620, 710, 720 is rotated in the same rotation direction. At this time, the roller 730 in the second pivoting bar 700 maintains the horizontality of the second pivoting bar 700 while making a rolling contact with the horizontal support plate 311.

As the rotary end of the first pivoting bar 600 approaches the edge of the panel 10, the rollers 1040 in the cutting means 1000 contact the upper and lower surfaces of the panel 10, respectively, and the main roller 800a and the main roller 800a. The tip of the edge band 20 drawn out from the edge band holder 900 is in close contact with the edge of the panel 10. If the distance between the corresponding rollers 1040 is too wide or narrow compared to the thickness of the panel 10, the holder 1010 is moved by driving the cylinder 1030 by operating a switch provided in the switch box 1200. The gap between the rollers 1030 and the gap of the blades 1020 are adjusted according to the thickness of 10.

Thereafter, when the motor 100 is rotated forward by manipulating a switch provided in the switch box 1200, the panel 10 rotates clockwise along with the lower turn table 400 and the upper turn table 500. At this time, a force that pushes the edge band 20 against the edge of the panel 10 by the first rotating bar 600 by the cylinder 610. Thus, the edge band 20 fits into a groove already formed at the edge of the panel 10. At the same time, the blade 1020 of the cutting means 1000 cuts both edges of the edge band 20 coupled to the edge of the panel 10 to match the thickness of the panel 10.

In this way, the edge band 20 is coupled to the edge of the rotating panel 10 and at the same time the operation of cutting the both edges of the edge band 20 is coupled, the switch operation is to complete the lower And rotation of the upper turntables 400 and 500. Then, the rear end of the edge band 20 coupled to the panel 10 is cut by hand. Thereafter, the panel 10 may be withdrawn after raising the upper turntable 500.

When you want to continue working in the automatic state, the above-described series of steps are repeated.

If you want to make the job semi-automatic; After the operation of the cylinder 610 is stopped by the switch operation, that is, it is allowed to work by using the second rotation bar 700 with no load. When the second pivot bar 700 is manually turned during operation, the first pivot bar 600 is pivoted in the same direction as the second pivot bar 700 by the gear trains 620, 710, and 720. Therefore, the first rotation bar 600 is operated by applying a force to the second rotation bar 700 without depending on the driving of the cylinder 610 by the air pressure of the compressor 200. By turning. In the manual operation, various switches of the switch box 1300 installed in the second rotation bar 700 may be operated to control the driving as in the self-working state.

Since the operation and operation of the device not described in other manual work correspond to the automatic work, the description thereof is omitted.

If, during the automatic operation or semi-automatic operation, the coupling failure of the edge band 20 occurs, the motor 100 is reversed by operating the changeover switch in the switch box 1100 of the main body 300 to turn the panel 10 clockwise. When rotated, the edge band 20 fitted to the edge of the panel 10 is removed by a length corresponding to the rotation angle of the panel 10. Therefore, after removing the edge band 20, it is possible to correct the coupling failure of the edge band 20 by performing the coupling operation again.

As described above, the present invention allows the edge band 20 of the panel 10 to be automatically and semi-automatically coupled to reduce work defects by manual operation, and simultaneously inserts the edge band 20 and the edge band ( 20) Since cutting of both sides of the edge is made automatically, the workmanship is shortened and productivity is improved.
