The upper sealer 5 'is elastically fixed upwardly on the upper sealer mount 25 by the upper sealer attaching portion 24 on which the spring 23 is mounted, and the upper sealer mount 25 is fixed to the upper sealer mount 25 by a pair of upper And is mounted on the upper end of the sealer connecting rod 26.

In the three-way seal film packaging machine of the present invention, the control section 9a includes a feed conveyor motor M3 for driving the feed conveyor 3 for conveying the packaging film 11, a conveyor motor M3 for driving the center conveyor 6 and the vertical sealer And a first control circuit 70 for controlling the vertical sealer motor M2 for rotationally driving the packaging film 11, 4, 4 'in synchronism with the conveying speed of the packaging film 11 (see FIGS. 1, 3, , Fig. 11).

In the three-way seal film packaging machine of the present invention, the control section 9a controls the horizontal sealer drive motor M1 so that the distance Lb from the packaging film 11 at the time of contact La with respect to the packaging film 11, The pair of transverse sealers 5 and 5 'are moved in synchronization with the conveying speed of the packaging film 11 until the contact point La of the packaging film 11 at the separation time Lb from the packaging film 11, And a second control circuit 71 for shifting the conveying speed of the packaging film 11 up to a predetermined speed to thereby swing the pair of horizontal sealers 5, 5 '(Figs. 1, 3, 10, 11 ).

In the three-way seal film packaging machine thus structured, the operator (worker) guides the packaging film 11 from the formers 2 to the longitudinal sealers 4, 4 'in advance via the film tensioner 12, Directional seal pouch for packing the article 20 with the packaging film 11 by means of a punching machine (not shown). The heaters 36 and 37 of each sealer (see FIG. 11) are pre-energized so that the packaging film 11 can be welded and fused with the longitudinal sealers 4 and 4 ' And the temperature is controlled.

When the operator (operator) puts the package 20 on the supply conveyor 3 and presses the package start button (not shown) of the operation panel 13, the supply conveyor 3 is placed in the conduction / control box 9 And is driven by a conductive portion 9b mounted inside the conduction / control box 9 from a supply conveyor motor M3 mounted outside of the control /

At the same time, the control section 9a provided in the conduction / control box 9 detects the feed amount of the feed conveyor 3 by the wrapping length encoder 72, and the control signal is inputted.

The vertical sealers 4 and 4 'are connected to the conduction / control box 9 (not shown) by the second control circuit 71 of the control unit 9a, from the longitudinal sealer motor M2 mounted outside the conduction / control box 9, And the packaging film 11 having a shape in the three-directional seal barrel is longitudinally sealed by the former 2 by the former.

The packaging film 11 containing the wrapped product 20 in the longitudinally sealed state is conveyed to the pair of transverse sealers 5 and 5 'by the center conveyor 6 driven by the conductive portion 9c.

The control unit 9a provided in the conduction / control box 9 detects the motion of the horizontal sealers 5 and 5 ', and receives control signals from the lateral sealer origin sensor 74 and the lateral sealer speed sensor 75 .

The double crank mechanism 35 is constituted by the first control circuit 70 of the control section 9a and the horizontal sealer drive gear 33 and the horizontal sealer driven gear 32 driven by the horizontal sealer drive motor M1 And the lower sealer 5 of the pair of horizontal sealers 5 and 5 'is driven up and down by the lower sealer connecting rod 52. At the same time, And the upper sealers 5 'of the pair of transverse seals are driven up and down by the upper sealer connecting rods 26. [ Thus, the double crank mechanism 35 drives the pair of horizontal sealers 5, 5 'up and down so that they are mutually approaching and spaced apart, that is, shifted in phase by 180 degrees in synchronism with the conveying speed of the packaging film 11 (a), (b)).

At the same time, the slider crank mechanism 50 is rotated by the driving section 34 composed of the lateral sealer drive gear 33 and the lateral sealer driven gear 32 driven by the lateral sealer drive motor M1, The roller 51 caught by both ends of the horizontal sealer pivot shaft 54 which is fixed to the linear bar 56 and fixed to the linear bar 56 by the transverse sealer slider 52a is pivotally coupled to the elongated hole 52b, (See Figs. 4 (a) and 4 (b)) by slidingly moving by pivotal movement of the pair of horizontal sealers 5 and 5 '.

That is, the slider crank mechanism 50 causes the slider crank mechanism 50 to move in the direction of the conveying speed of the packaging film 11 from the contact point La of the packaging film 11 to the separation point Lb from the packaging film 11, The sealers 5 and 5 'are moved and shifted from the transporting speed of the packaging film 11 from the separation time Lb from the packaging film 11 to the contact time La to the packaging film 11, Thereby rocking the sealers 5 and 5 '(Figs. 7 and 8).

In this case, as shown in Figs. 7 and 8, the pair of the transverse sealers 5, 5 'are arranged in a state in which the center line CL through which the packaging film 11 packed with the package 20 passes is interposed So that the clearance can be absorbed by the spring 23 provided on the upper sealer 21. [0064] The spring 23 also functions to properly regulate the welding and fusion pressure of the pair of transverse sealers 5, 5 'to the packaging film 11.

As described above, the pair of transverse seals 5, 5 'are combined with the up-and-down movement and the reciprocating motion which are out of phase by 180 degrees and move together while drawing the synthetic locus (UL, LL) The feed amount of the feed conveyor 3 is measured by the wrapping length encoder 72 by the welding and fusing of the three-directional seal pouches (5, 5 ') of the predetermined bag length according to the parameters set by the setting panel 10 20a.

The three-directional seal bobbin 20a thus formed is taken out to the carry-out conveyor 7 driven by the conductive portion 9c.
