Next, each operation of the above-mentioned packaging material feeding device and packaging device will be explained.

Before operating the device, the feed stage 36 as shown in FIG.
A large number of thin packaging materials m made of cellophane, vinyl, paper, etc. are placed in a stacked manner at a fixed position on the upper surface.

Then, the apparatuses A and B are brought into operation by turning on and operating a start switch (not shown) to rotate the motor.

As a result, the solenoid s1 is automatically temporarily activated. In connection with this, the clutch Ql performs the required operation, and the procerato 8 and the rotating shaft 5 are interlocked and connected, and the rotating shaft 5 is driven to rotate only one rotation. The rotation of the rotation shaft 5 causes the swing shaft 11 to swing once through the cam 9 and the like. When the swing shaft 11 is displaced in the direction of the arrow f4 in FIG. 2(a), the pressing body 20a is displaced downward via the arm 20, and as shown in FIG. packaging material m
and temporarily restrict its movement. Also, peeling means 1
The circular rubber 15.15 that forms part of the arm 14.14
and is displaced downward via the rectangular frame 16, as shown in FIG. 2(a).
As shown in the figure, it is pressed against the packaging material m. After this, when the swing shaft 11 is further swung in the direction of the arrow f4, the arm ]4
．． 14 is increased in its rocking displacement, and therefore the support frame 16 and the circular rubber 15, 15 are drawn toward the pressing body 20a via the shaft 17. Therefore, the circular rubber 15.15 causes only the uppermost layer of packaging material m1 to be peeled off from the lower layer of packaging material m, as shown in FIG. 2(a). Subsequently, when the swing shaft 11 is swing-displaced in the direction opposite to the arrow direction f4 and returned to its original position, the pressing body 20a, peeling means 13, etc. are also separated from the packaging material m and returned to their original positions. The rotating shaft 15 is rotated by the crank 7 and the link 43.
and also operates the moving body 39 via the arm 42,
At this point, the moving body 39 merely operates idly.

Solenoids S2 and S3 are then automatically activated at fixed timing. In connection with this, the clutch Q2 performs the required operation, and the sprocket 31 and the rotating shaft 28 are interlocked and connected, and the rotating shaft 28 is driven to rotate only one rotation. The rotating shaft 28 is rotated by the cam 28, the cam roller 35, and the lever 34a.
, the supply table 36 is swung once around the shaft 37 via the link 35. Therefore, as shown in FIG. 2(b), the supply table 36 is temporarily tilted greatly so that the packaging material m1 on the supply table 36 is
is pressed against the adhesive surface of the tape 47 forming the adhesive means 44 of the movable body 39. When the rotation shaft 28 completes one swing and the supply table 36 returns to its original position, only the top layer of packaging material ml has its front part adhesively removed, as shown in FIG. 2(c). It is in a state where it is adhesively suspended by the means 44. Note that the rotation of the rotary wheel 28 is also transmitted to the packaging device via the sprocket 29, but at this point, the packaging device B is only in idle operation.

The solenoid s1 is then automatically momentarily activated again.

In connection with this, as mentioned above (the rotating shaft 5 is rotated once, and in conjunction with the rotation of the rotating shaft 5, the movable body 39 moves to the second position).
As shown in Figure (d), the packaging material m is moved toward the station 38 in a state in which it is adhesively suspended. When the movable body 38 reaches just before the end point of conveyance, the swing shaft 11 is swing-displaced by the cam 9 as described above, and the pressing body 20a and the fil separation means 13 release the uppermost layer of packaging material m1 on the supply table 36. In addition, the locking arm 23 is temporarily displaced downward as shown in FIG.
The rear end thereof is pressed and locked onto the stationary table 38. Therefore, the packaging material m1 is forcibly pulled away from the adhesive surface of the tape 47 and released onto the stationary table 38. Simultaneously with the release, the wire serving as the regulating means 45 operates to press both sides of the front part of the packaging material m1 onto the stationary table 38. In other words, the packaging material m1 is positioned in the front and rear directions and is supplied onto the stationary table 38 in an accurate posture. After this, the moving body 39
is returned to its original position above the supply table 36 in conjunction with the rotation of the rotating shaft 5, and the locking arm 23 is also returned to its original upward position in conjunction with the swinging displacement of the swing shaft 11. do.

On one side of the operation of the movable body 39, the pressing body 20a is pressed as described above.
The peeling means 13 operates as shown in FIG. 2(a), and the uppermost layer of packaging material m1 on the supply table 36 is peeled off.

The packaging material m1 thus supplied onto the stationary table 38 is positioned below the ring body 89 and directly above the opening 68, as shown by the two-dot chain line in FIG. 7(a).

Thereafter, as shown in the same figure, the b-shaped agricultural product, which is the object to be packaged W, is placed in the enclosing body 106, which has an expanded diameter inside the opening 68.
It is inserted into the inside of the means from above and placed on the donut-shaped mat 105, and then lightly pressed downward with the hand holding the agricultural product.

In connection with this, the detection switch 116 is activated, and only the solenoid S2 is automatically temporarily activated. Therefore, the rotary wheel 28 is rotated only half a turn. The rotation of the rotating shaft 28 is transmitted to the bevel gears 53a and 53b via the sprocket 29 and the rotating shaft 50, and further to the gear 63 and the center tooth! 57 via each pivot shaft 56.59.60.61.
62.

The rotation of the cams 58.60a to 60d, 65.66.67 fixed to the respective rotation shafts 56.59.60.61.62 operates each part.

That is, 660 rotations of the cam is caused by the cam roller 114 and the lever 112.
and the flower-shaped cam 11 as a straight screw displacement via the link 113.
0. The linear displacement rotates the flower-shaped cam 110 about the support shaft 102 in the direction of the arrow f5, swings the enclosure 106 about the bearing 107, and reduces the diameter of the enclosure 106 means. As a result, the agricultural product W has the packaging material m1 attached to its body as shown in FIG. 7(b).

Next, the rotation of the flower-shaped cam 58 is transmitted to the four pressing plates 73 as an arcuate displacement toward the center of the opening 68 via the cam roller 58, assembly lever 84, support rod 85, etc. At this time, the arcuate displacements of the pressing plates 73 are carried out simultaneously, and the timing is almost the same as the diameter reduction operation of the enclosure means 106. As a result, agricultural products W are as shown in Figure 2 (b)
As shown in FIG. 3, the center portion of each side of the packaging material m1 is attached to the zenith of the four pressing plates 73.

The operation of the assembly lever 84 is also transmitted to the arm 86 via the link 87, causing the locking roller 72 to swing around the bearing 85. As a result, the three corners A, C, and C of the packaging material m1 are sandwiched between the ring body 89 and the locking roller 72, as shown in FIG. 7(b).

Next, the rotation of the cam 64d is performed by the cam roller 8 shown in the fourth rotation.
1. The displacement is transmitted to the moving roller 7]a as an arcuate displacement through a mechanism similar to the assembly lever 80, link 82, hook-shaped arm 75, and support rod 76. As a result, each corner 2 of the packaging material m1 is first stroked up along the zenith of the produce W by the moving roller 71a, as shown in FIG. 7(c).

Next, the rotation of the cam 64b is transmitted to the moving roller 71b in the same manner as the previous moving roller 71a, and as a result, the packaging material m1 is moved to the corner opposite to the previous corner 2, as shown in FIG. 7(d). The corner A can be stroked up along the zenith of the produce W by the moving roller 71b.

Next, the rotation of the cam 65 is controlled by a cam roller 97 and an M-shaped bar 94.
The rotation of the cam 67 is simultaneously transmitted to the presser plate 92 via the support rod 95 and the lever 99. Therefore, the presser plate 92 is displaced along the arrow direction f3 shown in FIG. 5 so as to press the top p of the produce W.

As a result, the two folded corners A and 2 of the packaging material m1 are temporarily pressed as shown in FIG. 7(e).
Corners A and 2 are prevented from opening during the transition to the next operation.

Next, the rotation of the cam 64c is transmitted to the moving roller 71d in accordance with the previous moving roller 71a, so that the packaging material ml passes through another corner opening to the moving roller 71a as shown in FIG. 7(f).
1d, the agricultural product W is stroked toward the top.

Next, the rotation of the cam 64a is controlled by the cam roller 81 and the assembly lever 8.
0, link 82, moving roller 7 via hook-shaped arm 75
1c, the corner portion C of the packaging material m1 after M is stroked up toward the top of the produce W by the moving roller 71c, as shown in FIG.

At this point, the rotation shaft 28 completes half a rotation, and the devices A and B temporarily stop.

Once the top part of the produce W has been folded and wrapped in this manner, the adhesive seal SL is applied by hand in the state shown in FIG. 8, and then the produce W is lightly pressed downward again.

In connection with this, the detection switch 116 is activated again, and this time the solenoid s3 is automatically activated.

Therefore, a clutch (not shown) operates in a predetermined manner, and the rotating shaft 28 is rotated by the remaining half turn. The rotation of the rotation shaft 28 is again performed by each cam 5864a to 64d, 65.66.6.
7, and the moving rollers 71a to 71d
, locking roller 72..., pressing plate 92, and enclosure 10
6 means returns to the state shown in FIG. 7(a) and the pressing plate 7
3... are also evacuated outward from the opening 68. Therefore, at this point, as shown in FIG. 9, the wrapped agricultural products W in the opening 68 are taken out.

On the other hand, due to the rotation of the rotation shaft 28, the supply table 36 is operated by the cam 9 in the same manner as described above, and the movable body 39 adhesively suspends the packaging material m1 via the adhesive means 44, as shown in FIG. 2(c). state. and - after a fixed time solenoid S
1 is automatically operated again, and the movable body 39 supplies the adhesively suspended packaging material m1 onto the stationary table 38 again in the same manner as described above, and returns to its original position. As described above, during the movement of the movable body 39, the uppermost layer of packaging material m1 on the supply table 36 is peeled off from the lower layer by the peeling means 13, etc., and the same process is repeated thereafter. .

In the above embodiment, the order of operation of the moving rollers 71a to 71d is an example, and a different order is optional.
