It is possible to freely rotate clockwise or counterclockwise by a predetermined rotation phase relative to 31. The drive for rotating this predetermined rotation phase is a pulse motor M2 (servo motor) connected to the vertical support shaft 30. It is done by.

A pair of endless chains 1 facing each other at a distance
One or both of the two phase adjusting sprocket bodies 33, 33 are loosened from the drive rotation sprocket 31 by loosening the screws 35, and are relatively moved with respect to the drive rotation sprocket 31. After changing the rotation phase by rotating the pulse motor M2 clockwise or counterclockwise by a predetermined circumferential angle by a predetermined rotation phase or by manually rotating it, tighten the screw 35 to drive the sprocket 31 for driving rotation and each of the above two phase adjustments. Sprocket body 33,
33 and 33 are integrally mounted and fixed to each other to change the rotational phase, and the U-shaped carrier plates 22
The pair of L-shaped carrier plates 22a and 22b facing each other in the front-back direction of the transport carrier constituting the above-mentioned carrier are brought closer or farther from each other to adjust the hold size of each transport carrier 11 in the transport direction. It is a thing.

In the above description, the diagonal carrier plates 22a in FIG. 4 (a) are fixed to the endless chains 12-1 and 12-4, and the diagonal carrier plates 22b are the endless chains 12-. 2 and 12-3 are fixed, but one of the carrier plates 22a and 22b, which is diagonal, is not fixed to the lower endless chain 12-3 or 12-4. Ie the upper endless chain 1
The configuration may be fixed to only 2-1 or 12-2. In this case, the lower endless chain 12-3 or 12-4 which does not fix the carrier plate may be omitted. In this way, in the case of not being fixed to the lower endless chain, it is preferable to use a carrier plate for performing the alignment movement later.

Further, the carrier plate 22a for transporting the rectangular tube container,
22b is L-shaped, but both do not necessarily have to be L-shaped, and one diagonal carrier plate may be, for example, a flat plate type. In the first invention, the flat plate type carrier is the carrier plate 22b and the second plate.
In the invention described in (1), it is a carrier plate which is moved afterwards for alignment.

EFFECTS OF THE INVENTION The carrier for a square tube container filling machine according to the present invention is used for changing the size of the carrier when the square size of the square tube container to be filled is changed by using a filling machine. There is an effect that it is possible to easily change the setting to a transport carrier size suitable for the size size with a small amount of labor.

Further, according to the second aspect of the invention, even after the size is changed, since the front and rear, right and left corners of the rectangular tubular container, particularly the top portion (top portion) which is easily deformed unlike the bottom portion, is held and conveyed, the capacity of the container is reduced. Is large and is tall, especially due to the internal pressure of the container after the contents are filled, the top part (top part) of the rectangular tube container
Does not change from a diamond shape to a square shape or an inverted diamond shape.

That is, normally, after the container is filled with the contents, the internal pressure of the contents weakens the repulsive force against the carrier plate due to the acute-angled portions of the rhombus in cross section of the rectangular cylinder container. Since you hold the front, back, left and right, you do not have to worry about that.

Therefore, the square tube container is securely held by the carrier plate, and as a result, the heat at the time of heat-sealing the top portion, which is a post-process, is evenly applied, and the pressure at the time of pressing is also uniformly transferred, resulting in poor sealing. It is possible to reliably prevent the leakage of the contents and the like due to.

Further, since the front and rear and right and left of the rectangular tube container are held by the L-shaped carrier plates, the container does not become twisted during transportation, and the vertical movement during filling and deformation of the container during transportation can be prevented. It never happens.
