包装物を挿入する包装装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous bag band transfer device for a packaging device, and in particular, a flat tube made of synthetic resin film is formed with welded portions in the transverse direction at predetermined intervals. The film on one side near the welded portion is cut in the transverse direction to form an opening, and there is a gap between each opening and the welded portion adjacent to the welded portion of the film on the other side. A floating seal lower piece is formed, and a continuous bag strip is formed with discontinuous cuts in the transverse direction on the other side of the film corresponding to each opening, and each bottom of the continuous bag strip is In the direction leading from the opening,
A pair of pinch-type transfer rollers transfers each bag length by length intermittently, and each time the bag stops, the leading edge of the bag is impregnated by air from a blower, and the item to be packaged is inserted into this. This invention relates to packaging equipment.

る。 Conventionally, in this type of device, if the transfer rollers do not transfer the bags formed in the continuous bag strip according to the pitch, the stopping positions will vary and the bag portions will not get stuck due to blowing wind. However, the position of the guide or hopper that inserts the packaged item may not match, resulting in incomplete or impossible insertion of the packaged item, or misalignment between the opening and the device that seals the opening. , various inconveniences occur.

止するようにしている。 Conventionally, in order to adjust the operation of the transfer roller to the pitch of each bag part, continuous bag strips had printed patterns and letters on each bag part, and these were used as a series of register marks for optical devices such as phototubes. It is detected by a sensor, and the transfer roller is stopped in response to this detection signal.

し、何れの場合も、特殊な連続袋帯を製造しなけ
ればならず、連続袋帯の製造コストが高くなる。 In addition, when the continuous bag band is plain, the seal part that forms the bottom of each bag part is detected by the same optical sensor as described above, but this optical sensor is not only expensive, but also detects the seal part. If there is a slight change in the amount of light, such as when using a continuous bag belt, there is a risk of detection errors, so it is necessary to take the trouble to print a register mark on a plain object, or to create a hole or notch in each bag section of a continuous bag belt. A conceivable method is to place electrodes facing this part and electrically detect this part. However, in either case, a special continuous bag must be manufactured, which increases the manufacturing cost of the continuous bag.
そこで、この発明は、連続袋帯には特殊な加工
を施すことなく、しかも、高価な光学的センサを
用いることなく、市販のマイクロスイツチを利用
して、正確に一袋部ごと、その継目部を検出する
ためのものである。 Therefore, this invention uses a commercially available micro switch to accurately measure the joints of each bag without applying any special processing to the continuous bag band or using expensive optical sensors. It is for detection.

のものである。 Another purpose is that even if there are wrinkles (see Figures 8 and 9) in a part of the continuous bag band when it is rolled up, it can be smoothed out and When detected by the switch,
This is to prevent wrinkles in the continuous belt from being detected incorrectly.

とする包装装置用の連続袋帯移送装置である。 In this invention, welded parts are successively formed in the transverse direction at predetermined intervals on a flat tube made of synthetic resin film, and openings are formed by cutting the film on one side near each welded part in the transverse direction. A seal lower piece part slightly floating with respect to the film on the other side is formed between each of the openings and the welded part close to this, and For the film, a continuous bag band with discontinuous cuts in the transverse direction is used, and each bottom of the continuous bag band is moved in the direction leading from the opening by a pair of pinching type transfer rollers to measure the length of one bag. In a packaging device that transports the bags intermittently, and each time the bag is stopped, the most advanced bag section is impregnated with air from a blower, and the article to be packaged is inserted into this, the opening is provided in the middle of the continuous bag transfer path. A guide roller or a guide bar is provided for the lower part of the seal to engage with the outer position, and a micro switch is provided near this, and the contact piece is configured to allow the lower seal part to pass through the guide roller or guide bar. The microswitch is mounted on the machine frame so as to be in a position where it can come in contact with the contact piece and operate the microswitch.

の連続袋帯移送装置。[Scope of Claims] 1 Welded portions are sequentially formed in the transverse direction at predetermined intervals on a flat tube made of synthetic resin film, and an example of the film near each welded portion is cut in the transverse direction to form an opening. A seal lower piece is formed between each of the openings and the welded portion close to the welded portion, and is slightly floating with respect to the film on the other side, and corresponds to each of the openings. On the other side of the film, discontinuous cuts are made in the transverse direction. Using a continuous bag, each bottom of the continuous bag strip is moved in the direction leading from the opening by a pair of clamping type transfer rollers, so that one bag length is cut. In a packaging device that transfers the bags intermittently by size and impregnates the most advanced bag section with air from a blower every time the transfer is stopped, and inserts the article to be packaged into this, the opening is provided in the middle of the continuous bag transfer path. A guide roller or a guide bar is provided for the lower part of the seal to engage with the outer position, and a micro switch is provided near this, and the contact piece is configured to allow the lower seal part to pass through the guide roller or guide bar. The microswitch is mounted on the machine frame in such a way that it can come in contact with the contact piece and operate the microswitch when the lower seal piece contacts the contact piece. This serves as a stop signal for the intermittent transfer of the transfer roller, and the wrinkle-stretching member, which has a curved portion along the outside of the guide roller or guide bar and is brought into contact with an extremely small gap or low contact pressure, is connected to the machine frame. 1. A continuous bag band transfer device for a packaging machine, comprising a continuous bag band transfer device installed and equipped in the bag. 2. The continuous bag band transfer device for a packaging device according to claim 1, wherein the wrinkle stretching member is a leaf spring curved along the circumferential surface of the guide roller or guide bar. 3. The continuous bag band transfer device for a packaging device according to claim 1, wherein the wrinkle stretching member is an inelastic plate curved along the circumferential surface of the guide roller or guide bar.
