の移送制御装置に関するものである。[Detailed Description of the Invention] This invention intermittently transports a synthetic resin bag material belt by an intermittent transport conveyor, and processes the bag material belt each time the conveyor stops to transfer bags, bag-like articles (book covers, diapers). (including covers), etc., and especially when the two strips of bag material are transported by hanging two strips of bag material using a common pair of clamping type conveyor, it is printed on each strip of bag material. The present invention relates to a bag material belt transfer control device for ensuring that the bag, etc., after having been processed with patterns, characters, trademarks, etc., is positioned at a desired position.

不能になるおそれがある。 Conventionally, in this type of device, when two strips of bag material are sandwiched and transported in parallel by a common pair of gripping type conveyors (including transfer rollers) in a slippable manner, the left and right bag material strips are connected to the conveyor, respectively. The amount of slippage is slightly different, and even with the same printing machine,
Even if letters, patterns, etc. are printed on bag material strips made of the same material at predetermined pitches, each pitch may not be exactly the same due to the partial elongation or shrinkage of these bag material strips. When two strips of bag material like this are transported using a common pair of clamping type conveyor,
Inevitably, one of the bag material strips is transferred first, and as the intermittent transfer is repeated, the difference accumulates, and if processing is performed to match the printed pattern and letter position on one bag material strip, the difference will be reflected in the other bag material strip. Otherwise, there is a risk that the printed pattern or characters may be separated in the middle, or the processing may become defective or impossible.

している。 Conventionally, as a means of controlling such transfer dimensions, the dimensions for transferring a bag material strip at one time by a conveyor are determined by determining the size of the bag material strip by the pitch of a register mark (including a part of a pattern or letter) displayed on the bag material strip. The conveyor is conveyed for a slightly longer distance, and the mark is detected by each mark detection device, and the conveyor is stopped in response to this signal, thereby shortening the conveyance dimension of the two bag material strips and removing the preceding bag material strip. During the next conveyance period, a brake plate is brought into contact with only the bag material strip to apply a transfer load to the packaging material strip, causing slippage between it and the conveyor, and the preceding bag material strip is removed. is shortened to an appropriate transfer size.

ある。 However, as mentioned above, when the pitch of the register marks on two bag material strips is generally shorter on one side and longer on the other, or when the above tendency occurs in a certain part of a roll of bag material strip, Braking is applied continuously to only one side of the bag material band,
This biased operation applies a load only to the bearing at one end of the conveyor, and increases the number of times only one brake is operated, resulting in severe wear and tear on these devices.Also, the brake plate is normally operated by energizing a solenoid. However, if only one side is continuously excited, overheating may occur and there is a risk of burnout.

で、全体として寸法の不揃いな袋が製袋されるこ
とになる。 When the difference in pitch between the register marks of the two bag material strips is large, set the transfer dimension of the conveyor so that a transfer dimension that is longer than the pitch of the longer bag material strip is sent at each intermittent transfer, and Braking must be applied to match this to the short pitch, and with conventional methods and equipment, it is necessary to apply extremely strong braking, making delicate adjustments difficult, and resulting in bags with irregular dimensions as a whole. It will be packed.

This is to enable the strength of the transfer load to be adjusted depending on the magnitude of the tendency.

To manufacture these individual bags using
These bag material bands A and B wound into rollers are supported on original fabric support devices 24a and 24b, respectively,
The continuous bag material bands A and B are arranged in parallel and passed through a feeding roller 25, and then passed through a guide roller 26.

8 and 29, and then clamped onto the conveyor 11. Thus, the positions of the register marks 14a and 14b of the two bag material bands A and B are aligned in a straight line in the transverse direction. Further, the cloth 27 is placed over the bag material bands A and B at the guide roller 26 portion.

While detecting this, the two bag material bands A and B are transported by the conveyor 11 while corresponding to their mark pitches, processed by the processing means 13 at each stop, and the bag material bands A and B are processed at each stop. Individual bags are manufactured from B.

4b tends to lead, for example, when the register mark 14a of the bag material band A precedes the register mark 14b of the other bag material band B, the circumferential surface of the braking rotary roller 17 is in front of the bag material band A. by the motor 19 in the opposite direction to the transport direction, that is, in the same direction as the transport direction for the bag material band B.
Rotate slowly and maintain the rotation speed.

袋素材帯A又はBとコンベヤー11との間にスリ
ツプを起させて、この袋素材帯A又はBの移送寸
法を短縮させる。 By rotating the braking rotary roller 17 in the opposite direction to the preceding bag material strip A or B, the frictional resistance or load between the bag material strip A or B and the conveyor 11 is increased. A slip is caused in between to shorten the transport dimension of the bag material band A or B.
このようにして、二条の袋素材帯A又はBの移

傾向を示せば、モータ19の回転速度を更に高め
る。 In this way, if the two bag material strips A or B continue to be transported, and the bag material strips on the same side show a tendency to advance further, the rotational speed of the motor 19 is further increased.
逆に反対側の袋素材帯B又はAが先行する傾向

17を逆転させその回転速度を維持させる。 On the other hand, when the bag material band B or A on the opposite side tends to take the lead, if the braking rotary roller 17 is already rotating in the forward direction, reduce its rotation speed, or or stop it. When the vehicle is stopped, the slow braking roller 17 is reversely reversed to maintain its rotational speed.

負荷が与えられる回転速度であればよい。 It is sufficient if the rotational speed of the above-mentioned braking rotary roller 17 can be switched in 3 to 5 steps for forward and reverse rotation, and when the rotation speed is the fastest, the rotation speed of the brake rotation roller 17 can be changed over the length of one bag by the conveyor 11. It is sufficient that the rotational speed is sufficient to apply a transfer load to the extent that the length can be shortened by about 10 mm compared to other bag material bands A or B.

を維持することができる。 As described above, in the apparatus of the present invention, the transfer load applied to the two bag material strips A and B is changed by rotating the braking rotary roller 17 in the forward or reverse direction. It is possible to correct the tendency to
This can be sufficiently corrected by further increasing the rotational speed of the braking rotary roller 17 according to the dimensional difference.
By maintaining the rotational speed of the braking rotary roller 17 in accordance with the tendency of deviation in the transfer dimensions of the two bag material bands A and B, it is possible to maintain a state in which the deviation is corrected.

However, its position does not move, and only the braking rotary roller 17
Since this is simply performed by rotating forward and backward and by changing the rotational speed, the mechanical structure is extremely simple and the braking operation itself is easy. For example, a control device is used that determines whether the signals entering the mark detection sensors 15a and 15b are before or after and measures the time difference between the two, and accordingly issues a command signal to change the rotation speed of the motor 19 in the forward or reverse direction. This further improves the effect of controlling the transfer dimensions of the two bag material bands A and B.

ある。 In this invention, the braking rotary roller 17 and the motor 19 are both movable in the direction perpendicular to the surfaces of the bag material bands A and B,
Due to this displacement, it is also possible to use it as a device that rotates the bag material strip on the side receiving greater contact resistance in a direction where the resistance increases.
