Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elliptic tube container feeding jig for constantly feeding an elliptical tube container to a tube container contents filling machine.

[0002]

2. Description of the Related Art In a tube container contents filling machine, a tube container having an open bottom is held in an inverted shape in a cylindrical tube holder, and after filling the contents from above, the bottom opening To block.

FIG. 5 shows the tube holder 2 described above. Four holding members 3 urged inward by springs are provided on the inner surface, and the holding members 3 hold the tube container 1. It is like this.

In order to supply the tube container 1 to the tube holder 2, a tilter having a U-shaped groove on the upper surface and rotatable by 90 ° is installed in the vicinity of the tube holder 2 and the bucket of the transfer device is provided. After transferring the tube container 1 sent by the above into the U-shaped groove of the tilter, the tilter is rotated 90 ° to drop the tube container 1 into the tube holder 2 from its upper part in an inverted shape, and then it is provided above. The pushing device pushes the holding member 3 inside.

[0005]

In the above conventional apparatus, when the planar shape of the shoulder portion of the tube container 1 is a perfect circle, the tube container 1 is supplied into the tube holder 2 with almost no trouble.

However, in the case of a tube container in which the shoulder has an elliptical planar shape, the tube container is placed in a U-shaped groove of a bucket or a tilter of a carrier (that is, a state in which the minor axis of the ellipse is inclined). Therefore, if it is sent to the tube holder 2 in this tilted posture, it cannot be smoothly pushed into the holding member 3, and the tube container 1 may be damaged during pushing. There was a problem.

In order to solve this problem, a bucket provided with a U-shaped groove matching the outer diameter and the curvature of the elliptical tube container 1 is used.
The bucket must have a certain length or longer in order to set the posture of No. 1 and the displacement force for correcting the posture must be applied to the bucket or the elliptical tube container 1 as an external force, and therefore There is a problem in that the mechanism portion for supplying the elliptical tube container 1 from the device to the tube holder 2 requires a large space and the structure thereof becomes complicated.

Therefore, an object of the present invention is to provide an elliptic tube container supply jig which can always supply a tube container having a shoulder with an elliptical planar shape to the content filling machine in a regular posture. There is.

[0009]

In order to achieve the above object, the present invention is a jig for supplying an elliptical tube container to a tube holder of a contents filling machine for a tube container, into which the elliptical tube container can be inserted. It has a substantially circular inlet and an outlet with the same shape and size as the same elliptical tube container, and the cross-sectional shape in the middle changes continuously from the shape / dimension of the inlet to the shape / dimension of the outlet. A guide hole for

The guide hole may be formed in a twisted shape in which the major axis of the cross-sectional shape is rotationally displaced by a predetermined angle from the inlet to the outlet.

The guide hole may be formed in a straight shape in which the major axis of the cross-sectional shape is at the same position from the inlet to the outlet.

[0012]

[Operation] The elliptical tube container which is supplied upside down at the entrance of the guide hole slides down inside the guide hole due to its own weight, but the guide hole has the same shape and size as the elliptical tube container at the exit. Since the cross-sectional shape is continuously changing, the tube container, even if it is supplied to the inlet in any posture, is corrected in the posture during sliding and reaches the vicinity of the outlet. Next, the tube container is supplied to the tube holder by the pushing device in the regular posture, and thus is smoothly held by the tube holder.

[0013]

1 and 2 show a first embodiment of the present invention. In the figure, 10 is an elliptic tube container supply jig (hereinafter, abbreviated as a jig), which is formed in a rectangular tube shape and is installed in a vertically long shape above the tube holder 2. This jig 1
0 has a guide hole 11 penetrating in its longitudinal direction,
The inlet 12 on the upper surface is formed in a substantially circular shape (a perfect circle or an ellipse) having a size into which an elliptical tube container (hereinafter abbreviated as a tube) 1 can easily enter, and the outlet 13 on the lower surface is formed as the tube 1. It is formed into an elliptical shape having substantially the same shape and substantially the same size.

The guide hole 11 has a cross-sectional shape in the middle thereof from the shape and size of the inlet 12 to the shape and size of the outlet 13.
It changes continuously so that it becomes the dimension, and the major axis a is the inlet 1.
It is formed in a twisted hole that can be rotated by 90 ° from 2 to the outlet 13.

The tube 1 is intermittently supplied to the inlet 12 of the jig 10 in an inverted state by, for example, a tilter.

The tube 1 supplied to the inlet 12 slides down in the guide hole 11 due to its own weight.
No. 1 continuously changes its cross-sectional shape at the outlet 13 so that the tube 1 has substantially the same shape and size as the tube 1, so that the tube 1 may be supplied to the inlet 12 in any attitude, and the attitude during sliding Is corrected and reaches the vicinity of exit 13.

Further, since the guide hole 11 is formed in a twisted shape as described above, the tube 1 has a posture in which the short axis of the guide hole 11 and the long axis b of the tube 1 coincide with each other.
Even if the gas is supplied into the guide hole 11, the long axis b of the tube 1 is always deviated from the short axis of the guide hole 11 due to the entry displacement of the tube 1 in the guide hole 11. The tangent line at the contact point C between the inner surface of the tube 1 and the outer circumferential surface of the shoulder portion of the tube 1 and the long axis b of the tube 1 do not maintain an orthogonal posture, and as shown in FIG. The tube 1 pivotally displaces its posture in the acting direction of the component force F of the force acting on C (by gravity). Therefore, the tube 1 has a guide hole 11
It will always slide smoothly without being stuck inside and stopping.

When the tube 1 reaches the vicinity of the outlet 13,
A pushing rod of a pushing device (not shown) provided above the jig 10 is lowered to push the tube 1 into the holding member 3 (FIG. 5) of the tube holder 2.

Since the outlet 13 of the guide hole 11 has a proper posture with respect to the tube holder 2, the tube 1 is always supplied to the tube holder 2 in a proper posture, and is smoothly pushed in. Therefore, the filling work can be efficiently performed.

The twist angle of the guide hole 11 is 180.
It is preferably up to about 0 °, but about 90 ° is particularly preferable.

A second embodiment of the present invention is shown in FIG. In the jig 20 of this embodiment, the guide hole 21 is formed in a straight shape instead of a twisted shape. That is, from the inlet 22 to the outlet 23, the major axis a of the guide hole 21 is at the same position without being rotationally displaced. Other configurations are similar to those of the first embodiment.

In this embodiment, the tube 1 has the inlet 2
If the short axis of the guide hole 21 and the long axis b of the tube 1 coincide with each other as shown in FIG. 4 when entering 2, the tube 1 may be clogged and stopped.
Therefore, if a means for supplying by inclining the long axis b of the tube 1 with respect to the short axis of the guide hole 21 is provided in advance, the guide hole 21
It is possible to completely prevent clogging of the tube 1 inside.

In each of the above embodiments, the jig 1 is used.
0, 20 and the tube holder 2 were installed vertically,
These may be installed horizontally and the tube 1 may be pushed into the guide holes 11 and 21 from the beginning by a pushing device.

[0024]

According to the present invention, a tube container having a shoulder with an elliptical planar shape can be always supplied to the contents filling machine in a regular posture, so that the contents can be transferred from the carrier device to the contents filling machine. The supply of the tube container can be achieved accurately and smoothly.

Further, if the guide hole is formed in a twisted shape, it is possible to prevent the tube container from being clogged in the guide hole. Therefore, it is possible to safely achieve the supply of the tube container from the conveying device to the content filling machine. You can

Since the turning posture of the tube container is properly regulated only by passing through the guide hole, the space required for the mechanical portion for correcting the turning posture of the tube container can be greatly reduced and its configuration can be reduced. Can be simplified.
