May be provided.

Next, the operation of the above embodiment will be described.

First, the operation of the first embodiment will be described with reference to FIGS.

The tip of the tube T is set on the roller section 4 by the operator through the guide section 7a.
The control means 21 operates the roller part 4, the cut part 5, and the seal part based on the signal of the mark detection means 2, and the tip unnecessary portion of the tube whose dimensions are not accurate. (A portion shorter than the length of a predetermined packaging bag) is cut.
The tip of the tube T is moved (sent out) by the operation of the roller unit 4 to hold the cut seal holding unit 8, the cut unit 5,
The sheet is conveyed to the opening 13 of the transfer means 3 through the seal section 6, the transfer section 10, and the guide section 7b (at this time, the transfer section 10 and the guide section 7b are substantially as shown in FIG. 1). It is in a horizontal state.) Then, the tip of the tube T is detected by the tip detecting section 14, and the detection signal is sent to the control device 21.

The control means 21 temporarily stops the operation of the roller section 4 based on the detection signal of the tip end detection section 14 and performs tuning.
At the same time as the transfer of the tube T is stopped, the tube T is held by the holding portion 12 (see FIGS. 2 and 3). Thereafter, the control means 21 activates the roller unit 4 again, receives the photo mark detection signal from the mark detection means 2 and outputs a delay circuit (not shown) incorporated in the control means 21. Stop after a certain period of time. The position of the tube for making a packaging bag of a predetermined length is set at the position of the cut portion 5 and the seal portion 6.

On the other hand, at the same time when the roller section 4 is restarted,
The transfer section 10 and the tension roll section 9 operate and move downward. By this action, the tube T conveyed from the roller portion is received in the receiving portion 11 while being flexed in a tensioned state by receiving an external force due to the downward movement of the tension roll portion 9. Also, as described above, the predetermined position of the tube T is set in the cut portion 5 and the seal portion 6. Then, the control means 21 operates the cut section 5 and the seal section 6 to form a packaging bag of a predetermined length (see FIG. 3).

At this time, the opening 1 of the transfer means 3 has already been set.
3 is operated by the control means 21 to open the tip of the tube T after the tip of the tube T (upper bag mouth seal side) is conveyed to the opening 13 (see FIG. 3).

The control means 21 operates the holding part 12, the tension roll part 9 and the transition part 10 to return to the original state, and at the same time, activates the arm part 22 to be opened. Holding the tube T,
(See FIGS. 4 and 5). The filling means 23
The packaging bag moved to is filled with a certain amount of items to be packaged,
The top of the packaging bag is sealed.

On the other hand, a case in which packaging bags of different lengths are made by the same automatic packaging machine will be described. In this case,
The tube T is changed to a tube on which a photo mark is printed at intervals according to the lengths of the packaging bags of different lengths. In the automatic wrapping machine of the present invention, even if the tube is changed in this way, the tube portion longer than the cut portion 5 and the opening portion 13 is formed by the transfer portion 10 and the tension roll portion 9. The cut portion 5 is accommodated in the accommodation portion 11 by the operation of
Since the predetermined position of the tube T is set in the seal unit 6 and the seal unit 6, the same automatic packaging machine can produce packaging bags of different lengths.

Next, the operation of the second embodiment will be described with reference to FIG.

The details are the same as in the first embodiment. After the tip of the tube T is conveyed to the opening 13, the tube T
The holding portion T is held by the holding portion 12. Then, as described above, the tube to be further transported is held by the holding unit 1.
The tube is bent upward and accommodated in the accommodating portion 11 between the seal portion 2 and the seal portion 6, and a predetermined position of the tube is provided at each position of the cut portion 5 and the seal portion 6. Will be set. In the second embodiment, the cut portion 5 and the seal portion 6 are set by setting the interval between the seal portions 6 facing each other through which the tube T passes as small as possible. No wrinkles can be formed on the tube part.

Next, the operation of the third embodiment will be described with reference to FIGS.

The control means 21 responds to the data of the length of the packaging bag which has been input and set to the control means 21 in advance.
The tension roll 17 is actuated (moved downward) so that the predetermined printing position of the tube comes to the printing means 15. At this time, the tube T is accommodated in the accommodation portion 19 while being bent. The printing means 15 performs printing on the tube T set in the printing means 15 as described above. The tube is transported by the roller unit 4 in units of a fixed length of the packaging bag. Therefore, the tension roll portion 17 does not need to be moved and adjusted for each packaging bag during the production of packaging bags of the same length after the position is set once. Further, since the tube T set in the printing means 15 is in a tight state without sagging, printing is performed at a fixed position on each packaging bag. According to the third embodiment, the tension roll 1
By changing (adjusting) the set position of 7, printing can be performed at an arbitrary position of the packaging bag.

On the other hand, a case where printing is performed on packaging bags of different lengths by the same automatic packaging machine will be described. Even when printing is performed at predetermined positions on packaging bags of different lengths, the control means 21 performs printing at predetermined positions by adjusting the distance by which the tension roll portion 17 is lowered. I can do it.

Further, the automatic packaging machine of the present invention can adjust the movement of the cut section and the seal section as in the conventional case (in the case of producing packaging bags of different lengths).
5 can be provided at an arbitrary position between the opening 13 and the roller 4 to perform printing. (However, the change of the printing position is performed by adjusting the movement of the printing means as in the related art.)
