Fig. 3 illustrates the manufacturing equipment of the angle sheet bag in one embodiment of the present of invention.The manufacture method and the equipment of angle sheet bag are described now.An example that angle sheet bag is manufactured left and right two row at first is described.
Pulled out by the loose winding roller and material is rotated rod from vertical attitude by one and changes horizontal attitude into from the material of material roller 11 output.Material is cut into two halves in the central, and these two halves are separated into and are a pair of flat up and down film 12a and 12b, and this forms two the plane surface 2a and the 2b of left and right two row bag main bodys 2 to flat film 12a and 12b.In other words, flat film 12a and 12b are made in vertical direction opposite one another flat film 12a and the 12b front surface and the rear surface that become bag by a transmission unit of being made up of conveying roller 13 and analogue 14 transmission.Material is to supply with continuously, but flat film carried off and on by all unshowned index roller in several work steps afterwards or analogue, and other operations are carried out at the flat film stopping period of intermittent delivery.
Fig. 4 illustrates side film 15 and is plugged on situation on the flat film 12b.Before a pair of flat film 12a and 12b are relatively put together, have opposite one another V-arrangement film 15a and the side film 15 of 15b be plugged on the following flat film 12b with direction by a side film plant unit perpendicular to flat film 12a and 12b transmission direction.This side film 15 is to extend and to form the both sides 2c and the 2d of left and right two row bag main bodys 2 perpendicular to the direction of flat film 12a and 12b transmission direction.Side film 15 forms the position at transmission direction forward and backward two side surface 2c and 2d.The left side of V-arrangement film 15a and right side form the side surface 2c of left column bag and right row bag respectively, and the left side of V-arrangement film 15b and right side form the side surface 2d of left column bag and right row bag respectively, and the opening of V-arrangement film 15a, 15b is set to relative to each other.Like this, side film 15 can be four side surfaces of side formation of four bags adjacent to each other altogether in two row about transmission direction.Side film 15 is plugged on the plane surface 15b with the direction (direction 2 among Fig. 4) perpendicular to flat film transmission direction (direction 1 among Fig. 4).
Fig. 5 illustrates another example of side film.This side film 16 is that the two ends 16c that makes film that on pleat trace 16b the two ends 16c of an oblong film inwardly turned back forms on line of centers 16a.
What Fig. 6 illustrated the side film still has an example.Side film 17 is flattened to form also by a tubular film 17a can make the pleat trace in its both sides.The seamless circular tubular film of being made by drawing can be used as tubular film 17a.
In the above-described embodiments, side film 15 all is to plant with the direction perpendicular to flat film 12a and 12b transmission direction, but side film 15 also can be planted with the direction (direction 2 among Fig. 7) identical with 12b transmission direction (direction 1 among Fig. 7) with flat film 12a as shown in Figure 7.The also non-sticking knot of side film 15 is at following flat film 12b but on being bonded on the flat film 12a.In addition, when side film 15 is formed by two V-arrangement film 15a and 15b, V-arrangement film 15a and 15b can temporarily be bonded in respectively on flat film 12a and the following flat film 12b, apart from one another by opening a suitable distance, like this when a pair of flat film 12a that will be mutually relative and 12b put together, the side surface 2c and the 2d of the bag main body 2 of transmission before and after this two V-arrangements film just can form respectively.
Fig. 8 illustrates example in addition of the side film that is plugged between flat film 12a and the 12b.Side film 23 can be combined by two ship shape film 23a and 23b, they are preparations like this, one oblong film is folded on the heart line therein, form end pleat trace 24, on pleat trace 24 from the point of electing basic point P as with in contrast to the direction of former inverted pleat direction with the side film one end that folds, and at two the angle Q in film termination or near it and on the connection lead of basic point P the inward direction of side film to angle sheet bag folded into, form chimb 25.When making side film 23, can no longer need to turn back side film 23 so that form open surfaces thereon.
After on the flat film 12b that plants, side film 15 can temporarily fuse on flat film 12b as shown in Figure 3 with side film fused unit 18 as hot weld are excellent.Synchronously upper and lower flat film 12a is in the same place with 12b is opposed with film placement unit 19 as placement roller then.The flat film 12a of formation band- like film 20 and 12b and side film 15 are again by side film fused unit such as the seam of hot weld rod.
Fig. 9 illustrates the fused surface of side film (Fig. 4) and flat film 12a and 12b.In this work step, side film 15 (is decorated with the part of hatching) near the total length of the part (the opposed limit of V-arrangement film 15a and 15b) of central authorities and is all fused among Fig. 9 on longitudinally, come the side of the plane surface 12a of handle bag main body 2 and 12b and both sides 2c and 2d to link together like this.
In next work step, as Fig. 3 institute method, it is spaced apart that the right-hand member of a pair of flat film 12a and 12b and left end are formed unit 32 by an open surfaces that forms open surfaces 43.In the work step that this open surfaces forms, because the termination of using the suction pad of the flat film that transmits subsequently to aspirate flat film 12a and 12b, the space in the bag is swollen in vertical direction.As shown in figure 10, open surfaces 43 is to form on flat film 12a and 12b and side film 15 by outwards turn back the side film on a point as basic point of triangular plate pleat trace.
Figure 11 illustrates a kind of formation method of open surfaces.Shown in Figure 11 (A), owing to side film 15 on total length with flat film 12a and 12b fusion formation seam surface 22, therefore need on the inside portion of the single-point chain line 41 of flat film 12a and 12b, push down, on a some P side film 15 turned back gradually shown in Figure 11 (B) on the triangular plate pleat trace then as basic point with a pressing plate that is not illustrated.When turning back, keep lath 42 to be plugged on the part that to be turned back with one, side film 15 is being turned back to the original pleat trace of side film 15 terminations from any one some P as basic point, its direction is opposite with original pleat trace direction, and is forming chimb 45 on the connection lead of two angle Q of side film termination and basic point P on the direction of bag body interior.So just finish turning back as shown in figure 10.
Figure 12 illustrates the another kind formation method of open surfaces.In Figure 12, the end of flat film 12a is upwards turned back from the termination of flat film 12b fully, do not use and keep lath 42, and the end of side film 15 becomes two jiaos of Q in connection side film termination of chimb 45 and the line of basic point P folds into towards the inside of bag main body 2 along one, so just forms a leg-of-mutton open surfaces 43 on the side film.Reset the flat film 12a of such complete opening, and from choosing wantonly on the original pleat trace 44 that a bit extends to side film one end as basic point P side film 15 is inwardly being folded into, its direction is opposite with original pleat trace direction.So just can form shown in Figure 10 turning back.The line of cut that on behalf of the back, the two point chain line C.L among Figure 10,11 and 12 will illustrate.
In next work step, as shown in Figure 3, about being attached to by a chimeric sealing band connection unit 51 with the chimeric sealing band of the direction parallel transmission on the open surfaces of two row with flat film transmission direction.Chimeric sealed strip 53 is transferred out from the fixed reel 52 of forming connection unit 51.As shown in figure 13, connection unit 51 is transported to chimeric sealed strip 53 between flat film 12a and the 12b, and it is fused on the inwall of flat film 12a and 12b.The bull of chimeric sealed strip and parent part engage one another at that time, are maintained on the position between the open surfaces on the side film 15, and on an open surfaces, and parent part is fused on another open surfaces bull by heat fusion.For the side fusion that makes bag main body 2 is carried out easily, flattened by compression machine with the corresponding part of bag main body 2 sides on the chimeric sealed strip.
In next work step, as shown in Figure 3, the open surfaces that forms in flat film 12a and 12b termination is by an open surfaces fused unit 61 as the fusion of fusion bar.In this work step, bag main body 2 is fused on side in the whole zone on mouth 4 above tops.Bag main body 2 is all fused from the top of mouth more than 4 by the lateral section of chimeric sealing member to side film 15 terminations.
Figure 14 is illustrated in the band-like film 62 after the fusion work step is finished.Band-like film 62 be by continuously with about two row bags main body and the ends 63 be combined intos.So as mentioned above, the fusion of fusion work step and side film by open surfaces, the whole outside of bag main body 2 is all fused.
