As shown in Fig. 9, the film 1 is formed into a tubular shape by the molding member 6, and is formed of a high frequency electrode 10 and 11, and both edge portions of the film 1 are welded at high frequency to form a cylindrical shape. The film package 16 of the phase is formed. The contents of processed food and the like are continuously filled in the cylindrical film package 16 through the filling nozzle 5 from the metering pump 4. The film package 16 filled with the contents is continuously sent downward at a constant speed by the rotation of the film feed rollers 12 and 13. In the sorting mechanism 14a, the sorting rollers 14 and 14 are intermittently pressed, and the film packing body 16 filled with the contents is intermittently pressed flat and divided. This flattened portion is indicated by reference numeral 16a.

The binding / cutting unit 20 is driven up and down in accordance with the descending speed of the flattened portion 16a of the film package 16 by a drive mechanism not shown in its entirety. When the flat portion 16a of the film packaging body 16 and the binding / cutting unit 20 descend at almost the same speed, the following binding / cutting operation is performed.

In this binding / cutting operation, when the binding / cutting unit 20 descends in accordance with the falling speed of the film package 16, rotational power is input to the input shafts 23 and 31 shown in FIG. The input shafts 23 and 31 and the drive rotary bodies 25 and 33 which are integral with this rotate. While the driving rollers 26 and 34 move from the position indicated by the solid line in FIG. 2 to the position indicated by the broken line, the movement block 27 on the left side moves in the right direction, and in synchronization with this, the movement block on the right side. (35) moves to the left.

When both the moving blocks 27 and 35 start to move in a direction approaching each other, the follower roller 113 shown in Fig. 3A by the outer circumferential surface of the radius 25c of the disc cam 25a. ) Is moved to the broken line position, and the pair of buffer rollers 118, 118 is at the home position ①. Similarly, when the moving block 35 on the right side starts to move in the left direction, the floor roller 123 is indicated by a solid line in FIG. 3 (a) by the outer circumferential surface indicated by the radius 33c of the disc cam 33a. Position, and the pair of buffer rollers 127, 127 is at the origin position ③.

When the left and right moving blocks 27 and 35 approach in synchronization, they are fixed to the focusing member 41 fixed to the left moving block 27 and to the binding molds 43 and 44 and the preceding block 48. The wire cutting members 46 and 47 move in the guide block 65. At this point, the push arm 56 is rotated clockwise by the spring 57, and the push block 56a is in contact with the rear face of the preceding block 48. Accordingly, when the moving block 27 moves and the focusing member 41 fixed thereto moves in the right direction, the preceding block 48 is locked on the moving block 27 by the pressing block 56a. The upper and lower wire cutting members 46 and 47 held in the preceding block 48 move forward without changing their relative positions with the focusing member 41.

The wires W and W are cut by the blades 46c and 47c and the receiving blades 65b and 65b of the guide block 65. The state immediately before the wire W is cut | disconnected is shown to Fig.7 (a). At this time, the upper nose 76 and the lower nose 77 supported on the shaft 68 and the shaft 69 face each other in front of the wires W and W. As shown in FIG. Therefore, the wires cut through the noses 76 and 77 through the cutting member 46 and the grooves 46d and 47d of the 47, which are advanced from (a) to (b) of FIG. (W, W) is bent in a U-shape so that the U-shaped wires (W, W) are held in the sliding grooves (46a, 47a) of the cutting members (46, 47).

See (b) of Figure 7.

. Immediately after the wires W and W are bent in a U shape, the noses 76 and 77 retreat from the front of the cutting members 46 and 47.

Immediately after completion of the cutting of the wires W and W, the follower roller 59 shown in FIG. 1 is lifted by the elevation of the planar cam 29a and pressed through the drive arm 58 and the shaft 55. The arm 56 is rotated counterclockwise, and the push block 56a is separated from the back side of the preceding block 48, as indicated by the dashed line in FIG. 2, and the preceding block 48 and the wire on the movable block 27. The locks of the cutting members 46 and 47 are released.

Immediately after the pressing block 56a is separated from the rear face of the preceding block 48, the preceding block 48 reaches the position shown in FIG. 5, and the pair of regulating protrusions 61 and 61 provided in the preceding block 48 are provided. Touches the buffer rollers 118 and 118 at the home position ①. At this moment, the arm 112 is driven clockwise in Fig. 3 (a) by the disc cam 25a, and the pair of buffer rollers 118, 118 moves from the origin position ① to ② and stops, thereby regulating the projection. The positions 61 and 61 are stopped and positioned by the buffer rollers 118 and 118 moved to the position?. Immediately after the preceding block 48 moves to the right and contacts the buffer rollers 118 and 118, the buffer rollers 118 and 118 move from the origin position to the position ②, and thus, when the preceding block 48 stops. The shock at the back is relaxed, and the noise at the time of stopping is also suppressed.

On the other hand, when the moving block 35 on the right side moves in the left direction and the right focusing plates 93a and 93b reach the position shown in FIG. 5, the positioning shaft 78 fixed to the preceding block 92 , 78) make contact with the buffer rollers 127, 127 at the origin position ③. At this moment, the buffer rollers 127, 127 are driven to the position ④ at the origin position of ③ by the outer circumferential shape of the disc cam 33a. That is, immediately after the positioning shafts 78 and 78 provided in the preceding block 92 on the right contact the buffer rollers 127 and 127, the buffer rollers 127 and 127 move from the origin position ③ to the position ④, so that the focusing plate 93a The shock when 93b) stops is alleviated, and the noise at the stop is also suppressed. Then, the focusing plates 93a and 93a by the buffer rollers 127 and 127 at the position ④ are positioned at the positions shown in FIG.

The focusing plates 93a and 93b on the right side by the buffer rollers 127 and 127 in the position of ④ are positioned and stopped at the position shown in Fig. 5, and the preceding block 48 on the left side is buffered in the position of ②. In the state of being stopped by the rollers 127 and 127, as the focusing groove 41e at the front end of the focusing member 41 on the left side and the focusing groove 93d of the focusing plates 93a and 93b on the right side, The flat part 16a narrows and the film 1 is focused to some extent. And even after this state of FIG. 5, the left and right moving blocks 27 and 35 continue to move toward each other.

At this time, in the movement of the left side moving block 27 in the right direction, the bearing block fixed to the moving block 27 is fixed because the preceding block 48 is stopped by the buffer roller 118 at the. (51, 51) slides the guide shafts (49, 49) fixed to the preceding block (48) and moves to the right, so that the springs (52, 52) contract. The wire cutting members 46 and 47 fixed to the preceding block 48 do not move in the position shown in FIG. 5 and bind the sliding grooves 46a and 47a of the wire cutting members 46 and 47. When the guide protrusions 43e and 44e of the molds 43 and 44 slide, and the binding molds 43 and 44 and the focusing plates 41b and 41c move further to the right, the buffer roller ( The guide shafts 91 and 91 slide in the left direction in the preceding block 92 positioned at 127 and 127 so that the springs 94 and 94 contract. That is, the focusing plates 93a and 93b do not move in the position of FIG. 5, and only the mold block 95 moves to the left.

At this time, the focusing plates 41b and 41c on the left side approach the focusing plates 93a and 93b at the position of FIG. 5 to completely focus the film as the focusing grooves 93d on the right side and the focusing grooves 41e on the left side. At the same time, the concave portions 43g and 44g at the front ends of the binding molds 43 and 44 and the concave portions 96a and 97a of the right molds 96 and 97 narrowly contact the U-shaped wires W and W. As shown in FIG. 7C, the wires W and W are deformed in the form of the wire clip 3 so that the film 1 is tightened and bonded in two places.

만큼 이동하여, 와이어 절단부재(46)과 (47)이 결속금형(43,44)과 금형(96,97)과의 맞닿음에 간섭하지 않도록 되어 있다.In addition, just before the binding molds 43 and 44 and the metal molds 96 and 97 come into contact with each other, the floor roller 113 is turned to the third by the outer circumferential surface of the disc cam 25a shown in FIG. It is driven to the position of a broken line in FIG. (A), and the buffer roller 118 in the .position shown in FIG. 5 returns to the origin position (1). The preceding block 48 is moved to the left by the buffer rollers 127 and 127, and the wire cutting members 46 and 47 held on the preceding block 48 are also returned to the left. Therefore, at the final stage of the approach operation of both moving blocks 27 and 35, just before the binding molds 43 and 44 and the molds 96 and 97 come into contact, the wire cutting members 46 and 47 are removed. Retracting in the left direction, the wire cutting members 46 and 47 with respect to the contact portion of the mold as shown in (c) of FIG.

The wire cutting members 46 and 47 do not interfere with the contact between the binding molds 43 and 44 and the molds 96 and 97.

As described above, the two moving blocks 27 and 35 approach each other so that the concave portions 43g, 44g and 96a, 97a of the binding molds 43, 44 and the molds 96, 97 are completely abutted. Immediately before the tightening of the jersey wires W and W is performed, the roller 106 shown in FIG. 1 contacts the stopper 107, and the driving arm (1) moves by moving to the left side of the moving block 35. 103 is driven clockwise, the cutter support block 101 is moved leftward, and the cutter 100 is driven to a position where the film 1 is penetrated, as shown in FIG. The film 1 is cut in the middle of the portion where the clips 3 and 3 are formed. As a result, the film package shown in FIG. 8 is separated.

After the above binding / cutting operation is completed, the rotation of the input shafts 23 and 31 shown in FIG. 2 is driven in a direction away from the moving blocks 27 and 35. When the preceding block 48 on the left moves back to the left, the springs 52 and 52 extend, and the bearings 51 and 51 provided on the movable block 27 slide the guide shafts 49 and 49 to the left. By operating, the binding molds 43 and 44 and the focusing member 41 fixed to the moving block 27 move to the left direction. At this time, the floor roller 113 is driven by the disc cam 25a, and the buffer rollers 118 and 118, which have been moved to the origin position., Perform one reciprocating operation of ①-②-① again. When the above-mentioned binding molds 43 and 44 and the molds 96 and 97 come into contact with each other, the buffer rollers 118 and 118 returning to the position of ② are pushed to the left position by pressing the preceding block 48 which returns to the position of ①. As a result, when the moving block 27 and the focusing member 41 move in the left direction, the preceding block 48 moves relatively in the right direction.

Therefore, when the push arm 56 moving in the left direction rotates from the rising position indicated by the dashed line in FIG. 2 to the lowered position indicated by the solid line, the preceding block 48 moves relatively in the right direction. The pressing block 56a of 56 is lowered without contacting the rear portion on the left side of the preceding block 48, so that the pressing arm 56 can be reliably returned to the solid state shown in FIG.

Therefore, the focusing member 41 moves to the left side, and the rear end i (see FIG. 4) of the guide protrusions 43e and 44e of the binding mold 43 and 44 is connected to the wire cutting member 46, End portions of the sliding grooves 46a and 47a of the

), The resilient elastic force of the springs 52 and 52 can be alleviated. Therefore, the rear end (

) And termination (

) Does not collide with force by the elastic force of the springs 52 and 52, and this collision sound can be suppressed.

Also, when the moving blocks 27 and 35 on both sides return to the positions shown in Figs. 1 and 2, the buffer rollers 118 and 127 return to their respective origin positions 1 and 3, respectively. Then, the binding / cutting operation is repeated in accordance with the lowering operation of the film package 16.

As described above, in the present invention, when the moving block approaches and the film is focused, the shock when positioning the preceding block is regulated, and the impact sound can be suppressed. Further, when the film by the mold is bound, the wire cutting member does not interfere with the contact portion of the mold to return the wire cutting member as a buffer member. It is also possible to reliably engage the push block on the back portion of the preceding block holding the wire cutting member.
