In this state, the photoelectric tube 5 will catch the mark P,
The "delay" lamp of the phototube amplifier lights up and the voltage of the film tension (powder) brake 4 is increased. At this time, the voltage is increased largely (2 to 3 V) for a predetermined time (set by the timer) and the basic voltage is slightly increased (about 0.2 V). The same thing is repeated until the pitch matches, so gradually raise the basic voltage, and add a temporary voltage of 2V to 3V to it.

Lights up and the voltage of the tension brake 4 of the film is lowered. At this time, the voltage is lowered largely (2 to 3 V) for a predetermined time (set by the timer) and the basic voltage is lowered slightly (about 0.2 V). Since the same thing is repeated until the pitch matches, the basic voltage is gradually lowered, and the negative temporary voltage of 2V to 3V is reduced.

As shown in Fig. 7, the position of this deviation advances from the base point to a position 180 degrees before the base point. Range of position, 18 points from the base point to the base point.
The position up to 0 ° is defined as the range of the delayed position.
As shown in FIG. 6, the correction work of the deviation detects the mark P by the photoelectric tube 5, detects the position in the rotary encoder 6 at that time, and maintains the brake voltage when the detected position matches the base point.

Further, when the detection position does not coincide with the base point and is in the position where the rotary encoder 6 is delayed, the brake voltage is increased to increase the tension of the packaging film F so that the distance between the marks P ... To be executed.
The magnitude of the deviation is digitally measured by the number of pulses by the photoelectric tube amplifier 5A, and a correction control voltage corresponding to the pulse is applied to the brake 4 to make correction in a short time. Therefore, as shown in FIG.

It becomes possible to seal at the target sealing position in a short time. Further, it is possible to display on the display 7 how far or behind the target seal position is. Further, when the position of the material film F to be sealed and the photoelectric tube mark P are misaligned even though the length can be controlled, the conventional photoelectric tube 5 is used.
It was necessary to adjust the target seal position by shifting the position of or changing the cam angle, but the base point position can be easily changed by inputting the direction and distance to the target seal position on the input touch panel 8. That is, the rotary encoder 6 has an immovable counter reset signal of Z phase, and pulses are sent at equal intervals once per rotation. The base point sets the distance (pulse) from the position where the count of pulses when passing through the Z phase is reset (becomes 0) to the position where sealing is desired.

ない修正が行われる。According to the automatic seal gap adjusting device of the automatic wrapping machine of the second aspect, the wrapping film supply braking means is composed of a powder brake attached to the wrapping film reel mounting shaft, and the braking voltage can be adjusted by adjusting the braking voltage. Even if the packaging film has an appropriate tension, the braking of the seal alignment can be easily and effectively performed steplessly. According to the automatic seal gap adjusting device of claim 3, the control amount advances the position from the base point of the rotary encoder to 180 degrees before the base point, the range of the position, 1 from the base point to the base point.
The position up to 80 degrees later is defined as the range of the delayed position, and the range of the advanced position and the range of the delayed position are divided into multiple ranges, such as 8 multiples from the base point, and the braking voltage increases as the distance from the base point increases. Therefore, if the deviation is large, a large brake voltage can be applied to correct it in a short time, and when it approaches the base point, a small change in the brake voltage that was there causes a change in the deviation near the base point. Minor corrections are made.
