The slide chassis 85 is supported by the guide plate 88, and the guide plate is fixed to the rear (rear) chassis 86 through the studs 87.

The slide chassis 85 is guided and guided by the guide plate 88 so that the second roller group 82 moves relative to the first roller group 81 in the horizontal direction in FIG.

The film 1 continuously transported by the film transport device A is a guide roller 83a, a roller 82a, a guide roller 83a, a roller 82b, and a roller 81a of the first roller group 81. ) And the roller 81b are supplied between the upper 61 and lower 41 electrodes. The film 1 passed between the electrodes continues to move the rollers 81d and 81c of the first roller group 81, the rollers 82d, the guide rollers 83d, the rollers 82c, and the guide rollers 83c. Passing through it is guided out of the welding apparatus B from the guide roller 83c.

As shown in FIGS. 1 and 2, the left end of the slide chassis 85 on which the second roller group 82 is fixed is connected to the drive link via the joint 91. This drive link 92 is connected to the driven link 94 via a joint 93.

The driven roller 95 is supported by this driven link 94 and is in compression contact with the attention of the cam 97 by the elastic force of the string 96.

The cam 97 is supported by a drive shaft on which the slave sprocket 33 is fixed.

As shown in FIG. 3, the driven sprocket 33 is driven together with the driven sprocket 32, which is the driving source of the tape welding mechanism B ₁ , so that the second roller group 82 is fixed. The slide chassis 85 is driven in the horizontal direction in synchronization with the movement of the tape welding mechanism B ₁ . The slide chassis 85 and the second roller group 82 are driven in accordance with the shape of the cam 97.

In the welding operation by the tape welding mechanism B ₁ , the slide chassis 85 and the second roller group 82 are driven in the right direction in FIG. The speed at this time is 1/4 of the continuous transportation proficiency V of the film 1. If the second roller group 82 composed of four rollers 82a to 82d moves in the right direction at a speed of (1 / 4xV), the portion of the film 1 supported through the first roller group 81 is temporarily Is stopped. After the second roller group 82 has moved as far as possible to the right position in FIG. 4, the slide chassis 85 is returned to the left at the maximum speed in accordance with the shape of the cam 97.

The operation will be described below.

The film 1 is continuously sent out at a constant speed by the delivery roller 11 of the film transport apparatus A. FIG.

On the other hand, as shown in FIG. 3, the driving force of the drive sprocket 31 rotated by the power source in common with the power source of the filling packing device C is transmitted to the driven sprockets 32 and 33 through the chain 34. The drive shaft 35 for driving the tape welding mechanism B ₁ and the drive shaft 36 for driving the roller differential mechanism B ₂ are driven.

The tape welding mechanism B ₁ and the roller differential mechanism B ₂ are operated by the drive shafts 35 and 36 which are driven in the internal fastening state at the same time.

The cam 97 is driven in response to the rotation of the drive shaft 36, and the driven link 94 is driven according to the shape of the cam 97. In addition, the drive link 92 connected to the link 94 is driven, and the slide chassis 85 is then driven in the left and right directions in FIGS. 1 and 4. According to the shape of the cam 97, when the slide chassis 85 is driven at a speed of (1 / 4xV) in the right direction of the drawing (where V is a continuous transport speed of the film 1), the second roller group 82 ) Is moved relative to the first roller group 81, and the film 1 passing through the first roller 81 is temporarily stopped. After the slide chassis 85 is moved in the right direction, the slide chassis 85 is quickly returned to the left direction of the drawing in accordance with the shape of the cam 97. At this time, the film 1 passing through the first roller group 81 is transported at a speed higher than the speed V of the constant speed travel to make up for the delay of the tape transport operation due to the stop of the film 1.

On the other hand, in the tape welding mechanism B ₁ , the drive shaft 35 which rotates together with the driven sprocket 32 drives a cam different from the cam 53 shown in FIG. 5, and the lower portion 41 is operated by operation of each cam. ) And the upper electrode 61 and the tape feed roller 71 is driven.

At the operation timing of each member, the tape delivery roller 71 is rotated by a predetermined angle when the slide chassis 85 of the roller differential mechanism B ₂ is moved to the left in FIG. The tip of 2) is sent out on the lower electrode 41 by the length corresponding to the width of the film 2a. And when the slide chassis 85 of the roller differential mechanism B ₂ moves in the right direction of the drawing at a speed of (1 / 4xV), that is, when the film 1 passing through the first roller group 81 is stopped, The lower electrode 41 is moved upward by the cam 53 and at the same time the upper electrode 61 is downwardly moved.

As shown in FIG. 6, when the lower electrode 41 is moved upward, the tip of the tape 2 is pressed against the lower surface of the tip of the upper guide member 42a by the fastening member 45. As shown in FIG. The lower electrode 41 is raised later than the fastening member 45, and when the electrode 41 is raised, the cutter blade 41b provided at the end of the upper surface of the lower electrode 41 is at the tip of the upper guide member 42a. In contact, the tape 2 is cut into strips. Before and after the upward movement of the lower electrode 41, the automatic valve 43 (see FIG. 5) is opened for a predetermined time so that the tape suction hole 41d formed in the upper surface of the lower electrode 41 by the air suction device 44 Adsorbed from). Before the tape 2 is cut by the cutter blade 41b, the tip of the tape 2 is supported by the lower electrode 41 by the suction force.

Therefore, the cutting tape 2a is supported by the lower electrode 41 by air suction, is raised, and juxtaposed in contact with the welding position of the lower surface of the film 1. On the other hand, when the upper electrode holder 64 is lowered, the pressing portion 61a of the upper electrode 61 held by the electrode holder 64 causes the film 1 and the tape strip 2a to lower the lower electrode. It is crimped | bonded on the press part 41a of 41. FIG.

When a high frequency signal is applied to the two electrodes 41 and 61, the tape strip 2a is welded to the film 1.

The automatic valve 43 is closed during the welding operation so that adsorption by air is stopped.

The two electrodes 41 and 61 are then separated.

And the tip of the tape 2 is resent until the film 1 is stopped again, and the above operation is repeated.

The film 1 on which the tape strip 2a is welded by the welding mechanism B is conveyed to the filling packaging device C through the phase adjusting mechanism 13. In the filling packaging device (C), the film 1 is formed into a cylindrical shape while the film 1 is transported at a predetermined speed by the delivery roller 24, and the sealing member is sealed by the seal electrode 22. By 23, the processed food is filled into the cylindrical film. The cylindrical film filled with the processed food by the crimping roller 25 is crimped and the clip 4 is clamped in the crimping portion of the film in the fastening mechanism 26, and then the crimped portion is cut and processed. Food-filled packages are produced.

In the filling packaging device (C), when the cylindrical film filled with the processed food is tightened by the clip 4 in the fastening mechanism 26 and cuts the tightened portion, the tape strip 2a is placed in a place where it is clamped and cut. It must be attached. Therefore, as described above, the same motor is used as the power source of the welding device B and the filling packaging device C, and the two devices B and C operate in an internal binding state with each other. In the phase adjusting mechanism 13 shown in FIG. 1, the position of the roller 13b is shifted to change the length of the film 1 transported between the welding mechanism B and the filling packaging device C. The welded portion (2a) can be positioned to match the timing of operation of the tightening and cutting portions.

Thus, the operation of the two instruments and devices B and C is achieved by the same drive source at the same time, and the length of the film 1 between the two instruments and devices B and C can be adjusted, so that the tape The center part of (2a) can be cut | disconnected correctly in the filling packaging apparatus (C).

In the illustrated embodiment, as shown in FIG. 9, a tape strip 2a is welded to the film 1 at an interval of twice the unit length L of the stick-shaped packaging material. Thus, the stick-shaped package after completion has a tape strip 2a on which only one side is welded, as shown in FIG. Alternatively, the tape strip 2a may be welded to the film 1 at intervals of the length L to produce a package in which the tape strips 2a are installed at both ends thereof.

The apparatus can change the unit length L of the completed stick-shaped package. Adjustment of this length change is possible only by changing the conveyance speed of the film 1. Since the packing and packaging device C and the welding mechanism B are always tied together and always operated in a predetermined cycle, when the transportation speed of the film 1 is slowed down, the welding pitch of the tape strip 2a (for example, 2xL) The clipping and cutting pitch pitch L in the filling packaging device C is shortened, and the unit length of the package is also shortened. On the contrary, when the transport speed of the film 1 becomes faster, the unit length of the package becomes longer.

If the shape of the crimping portion 61a of the upper electrode 61 of the high frequency welding is changed, a welding portion 3a having a shape as shown in FIG. 10 may be formed.

7 and 8 illustrate another embodiment of the roller differential mechanism B ₂ .

In the embodiment of FIG. 7, the second roller group 101 has two rollers 101a and 101b. When the slide chassis 102 supporting the second roller group is moved in the right direction of the drawing at the speed of (1 / 2xV) (where V is the transport speed of the film 1), the first roller group 81 is placed on the first roller group 81. The speed of the supported film 1 is zero.

In the embodiment of FIG. 8, in contrast to the embodiment of FIG. 7, the second roller group 104 and the respective rollers 104a, 104b are fixed, while the respective rollers 103a, of the first roller group 103 are fixed. 103b) is supported by the slide chassis 105 and driven in the left direction in FIG. In this case, the film 1 passing through the first roller group 103 can be relatively stopped with respect to the lower electrode 41 by selecting the speed of the slide chassis 105.

In the above embodiment, since the vinylidene chloride-based resin film is used as the film 1, high frequency welding is adopted as a means for welding the tape 2a, but thermal welding and ultrasonic welding can also be used only with the welding water.

Stick-shaped processed foods such as sausage produced by the apparatus are shown in FIGS. 11 to 14. The stick-shaped package is formed in a cylindrical shape, and both ends of the stick-shaped package are sealed to each other. The tape strip 2a is fixed by a partial weld 3 to the part which is tightened by the clip 4.

In order to remove the film 1 from the processed food, one end of the cut tape 2a is sandwiched between the fingers and pulled as shown in FIG. Therefore, as shown in FIG. 14, the packaging film 1a is peeled off from the first end of the welded part 3, and the film 1 is easily removed.

As described above, according to the present invention, it is possible for the tape strips to be continuously and automatically deposited on the film at intervals from each other, and the sausage packaging film having the cutting tape is continuously produced. A sausage having a shape as shown in FIG. 11 can be continuously produced by internally binding a filling device for processed food such as sausage. Due to the electromagnetic clutch, the film is transported continuously without abrupt stopping and relatively stopped within the welding mechanism of the tape, so that the film is filled and packed when the filling filling device for sausages is installed at the rear of the welding mechanism of the film and tape. It is possible to stably feed into the apparatus and unnecessary excess tension affecting the film can be prevented. In addition, as described above, since the film is always stably supplied, the welding position of the tape to the finished package is not twisted. In addition, since the film is always supplied continuously, the tape welding operation and the sausage filling packing operation can be speeded up, thereby increasing the processing speed.

Since the film is apparently partially stopped by the relative motion of the two rollers, it is very simple to weld the tape to the film in the stationary state. Therefore, the structural design of the tape welding mechanism is easy.
