Abstract

PROBLEM TO BE SOLVED: To provide a packaging bag lateral move preventive device of a continuos high speed filling and packaging machine. SOLUTION: This relates to a packaging bag lateral move preventive device of a continuous high speed filling and packaging machine. A pair of right and left lateral move preventing disk panels which coaxially rotate at the bottom of many clamps provided on the periphery of a round table rotating intermittently are provided for clamping the bottom of a packaging bag held hanging down by the clamps and for preventing the lateral move of the bag.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing a package bag from rolling in a high-speed continuous filling and packaging machine.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a filling and packaging machine of this type intermittently rotates a packaging bag H suspended and held by a pair of right and left clamps 2 and 2 along a circular table 1 to stop the package. The packaging bag H is opened in order, the contents N are filled, the bag mouth F is sealed, cooled, and then discharged.

[0003]

However, the packaging bag H, which is suspended and held by the clamps 2 and 2 and intermittently rotates at a high speed, is horizontally moved before and after the intermittent rotation with the circular table 1 stopped as shown in FIG. It shakes, and after the filling of the contents N, it vibrates particularly violently, hindering the operation at the stop position, falling off from the clamps 2 and 2, falling off the contents N and the packing bag H There was a problem that the shape was distorted and distorted.

[0004]

According to the present invention, each packaging bag suspended and held by a clamp is pinched by a pair of anti-rolling plates to prevent rolling before and after intermittent rotation with a stop. This problem was solved.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, a circular table 1 which rotates intermittently has a pair of left and right clamp mechanisms 2, 2 which can be opened and closed outwardly from the outer peripheral end. 1 is provided with a disk 3 that rotates synchronously, and a pair of left and right anti-rolling plates 4a and 4b are attached to positions directly below each clamping mechanism 2.

As shown in FIGS. 3 and 4, the anti-rolling plates 4a and 4b are cam disks 5 coaxially mounted below the disks 3.
The opening / closing mechanism 8 includes a rotator 6 that rolls and rotates on the convex end face 5a and the concave end face 5b, and an opening / closing mechanism 8 including springs 7a and 7b for pulling back. The opening / closing mechanism 8 opens the roll prevention plates 4a and 4b at the position 9a where the packaging bag H is suspended and held by the clamp mechanisms 2 and 2 at the unloading position 9b as shown in FIG. The position is adjusted so as to be closed at positions from the filling position 10 of the contents N to the heat-sealing position 11, the cooling position 12, and the like before the carry-out position 9 b.

Therefore, at the position 8 where the packaging bag H is suspended and held by the clamp mechanisms 2, 2, the anti-rolling plates 4a, 4b
Since the gap is open, the supplied packaging bag H can be easily suspended and held, and the process of intermittently rotating to the next working position, particularly from the filling position 10 filled with the contents N to the primary, At the secondary heat seal sealing position 11 and the cooling position 12, the roll prevention plates 4a and 4b are closed so that the lower part of the packaging bag H is interposed and intermittently rotated as shown in FIGS. Therefore, the lateral movement of the packaging bag H is reliably prevented. Then, at the carry-out position 9b, the anti-rolling plates 4a and 4b are opened again, and the packaging bag H is released from the suspension and held and is carried out without any trouble.

[0008]

As described above, according to the present invention, the lower part of the packaging bag suspended and held by the clamp is closed and closed by the anti-rolling plate that opens and closes and is intermittently rotated. The effect of preventing the packaging bag from being detached from the clamp after filling the contents and falling off the contents and the bias of the contents caused by the shaking can be prevented.

[0009] By opening and closing between the anti-rolling plates,
There is an effect that the carrying-out work by hanging and holding the packaging bag by the clamp and unscrewing is smooth.
