In the map, numeral 57 indicates each air cylinder installation @2.
1.41 and 51, and is connected to each control valve 23.43 and 53 via an air tank 58 and an air pipe 59.

(Operation of the embodiment) First, the width of the packaging tray 20 is adjusted by moving the receiving member 20b of the packaging tray 20 with respect to the receiving member 20a according to the width of the bag material strips F□, F2 to be supplied. , fix both using set screws, etc.

The packaging tray 20 is placed together with the movable frame 70 so that the bag group B3 to be conveyed next is placed exactly on the packaging tray 20.
The movable frame 70 is fixed to the main machine frame 60 at an optimal position by adjusting the movement in the width direction using a feed screw 62 or the like.

The packaging pedestal 20 is placed in an upper standby position, and the auxiliary frame 50 is placed in a waiting position where it is lined up and does not overlap with the packaging pedestal 2o, and these positions are considered as nutart positions. At this time, the heat seal jaws 30a, 30b and 32a, 32b are in a mutually separated state.

Next, supply the desired bag material band F and F2 to the bag making device A,
Therefore, when all the devices of this embodiment are operated, first the bag making device A is operated.
, two bags B□ and B2 are manufactured side by side at the same time, and these bags B are placed in two places on the product tray 10 of the bag making device A.
1 and B2 are stacked one after another, and when the number of bags reaches a predetermined number, the detection device 11 issues an output signal. Using this signal as an input signal, the conveying device 80 is operated to stack the two groups of bags B1 and B4. At the same time, the bags are transported from the product tray 10 to the next station, a bag processing device, where each group of bags B3 and B4 is subjected to batch processing.

In the device of the embodiment, the punching device 15 punches out the handle portion to make a grocery bag. Immediately after this processing is performed, each bag group B3. B4 is transferred to the packaging device P by the conveyance device 80.
One group of bags B, the packaging cost, is conveyed to the table 20, and the other bag group B, the auxiliary bones, are conveyed to the table 50 at the same time.

This packaging cost is calculated by winding up the outer film band T connected to the film support device on the winding shaft 31 in advance to the necessary length while the table 20 is in the upper standby position, and unraveling it to separate it vertically. The winding shaft 31 is passed between the heat-sealing jaws 30a and 30b and the underside of the stand 20, and the wrapping shaft 31 is moved to the opposite side of the stand 20.

Next, the horizontal drive mechanism 51 and the control valve 53 are actuated, and the movable member 52 and the auxiliary frame move the stand 50 from the standby position to the bag group B on which the packaging bag is stacked on the stand 20. With reference to the movement direction of the group B4 in the width direction, the auxiliary bone moves horizontally until the rear end position passes the position of the upright sweeper plate 4o, and with this position as the end of the stroke of the movable member 52, the auxiliary bone moves the base 5o. make it stop.

Next, the control valve 43 of the second vertical drive mechanism 41 is operated to lower the upright sweeper plate 40 together with its movable member 42, and the lower edge 44 of the upright sweeper plate 40 fits into the uneven surface 54. In other words, the downwardly protruding portion of this lower edge 44 protrudes further downwardly than the bottom bag of the stacked bag group B4.

When the horizontal drive mechanism 51 is operated in the opposite direction to move the auxiliary bone table 50 back to the standby position again, the upper bag group B4 is prevented from moving by the upright sweeper plate 4o. Therefore, for this bag group B4, the packaging cost on the lower side of the stand 50 is paid out onto the stand 20 (see FIG. 7).

During this time, the winding shaft 31 previously winds up the required length of the exterior film band T, as in the previous case, and while unwinding it, passes between the heat seal jaws 30a and 30b and under the packaging tray 20, and wraps the film. Move it to the opposite side of the cradle 20.

Next, the packaging tray 20 is lowered by the vertical drive mechanism 21 in the same way as before, and the second vertical drive mechanism 41 returns the upright sweeper plate 40 to the upper standby position.

Next, the winding shaft 31 is returned to its original position while unwrapping the outer film band T, and the heat seal jaw 3 is
0a, 30b and open bottom heat seal jaws 32a, 32b
is operated to weld and cut the exterior film band T and weld one opening at the same time, and the packaging bag B is made by packaging this bag group B.
. is carried out from this packaging tray 20.

Finally, the packaging tray 20 is returned to the standby position by the vertical drive mechanism 21.

During these packaging steps, the bag making apparatus A continues to make bags one after another, and the above-described operations are repeated every time the next predetermined number of bags are made.

The sequential operation of each component described above is executed by sequentially commanding the multi-control valves 23, 43 and 53 based on a predetermined program from a control section C consisting of a sequence control device or a computer.

The movement of the winding shaft 31 and the operation of the heat sealers 30a, 30b and the opening heat sealers 32a, 32b are also performed by a reciprocating drive mechanism similar to the above-mentioned vertical or horizontal drive mechanisms. The winding shaft 31 is started and stopped by, for example, a pulse motor, and the bag group B3. The required length is previously commanded to the pulse motor by the number of pulses according to the width dimension and thickness of B4.

In addition to the above-mentioned air cylinder mechanism, each of the above-mentioned reciprocating drive mechanisms may include a hydraulic cylinder mechanism, a solenoid mechanism, a linear motor, other purely mechanical mechanisms such as cams and levers, or a combination of at least two of the above-mentioned mechanisms. They are the same for this invention.
