A chute opening guide 32 for restricting the lateral width of the chute opening is attached to the chute 20, and both ends on the inside of the opening face a pair of guide plates 28 of the bottle restriction guide and are slightly widened. That is, assuming that the total height of the bottle is A, the height to the shoulder of the bottle is B, and the diameter of the bottle bottom is C, the opening width of the chute opening guide 32 (the height direction of the bottle) is the same as when the bottle is inclined. It is set to a range longer than the length ((C ² + B ² ) ^1/2 ) and shorter than the total height A of the bottle.

Next, the operation will be described. The plastic bottle 13 randomly placed in the hopper 11 comes into contact with the belt inclined portion 9a entering the hopper 11 at various angles and is pressed against the belt inclined portion 9a by its own weight. By scraping the plastic bottle 13 that is vertically or diagonally inclined by the above, the plastic bottle 13 is laid sideways along the angle 24 on the belt inclined portion 9a, and it becomes easier to ride between the angles 24 of the conveyor belt 9. Further, the plastic bottle 13 rolls on the slope of the bottom of the hopper 11, and the last one is taken into the belt slope 9a and transferred. Further, the plastic bottle 13 is supported by the angle 24 and the peripheral surface thereof abuts on the conveyor belt 9 and is placed sideways. As shown in FIGS. 6 and 7, the plastic bottle 13 'in a poorly loaded state is a V-shaped stopper 26. Is moved to the edge side of the belt inclined portion 9a and discharged to the slide 27 while moving forward. The plastic bottle 13 'discharged to the slide 27 slides down and is returned to the inside of the hopper 11.

The plastic bottle 13 is transferred from the inclined belt portion 9a to the horizontal belt portion 9c. Here, the plastic bottle 13 is transferred by sliding the bottle bottom 13a and the bottle shoulder opening 13b to a pair of guide plates 28 of the bottle control guide, and the horizontal belt portion 9c does not support the plastic bottle 13 in the vertical direction. Therefore, the vibration prevention guide 31 prevents the plastic bottle 13 from being displaced by the bottle mouth 13c hitting the guide plate 28 due to the vibration during conveyance. Poly bottle 13 shoots
When it approaches the drop position of 20, it separates from the guide plate 28 and the delivery end
Fall from 9d. Then, as shown in FIG. 1, first, the bottle mouth 13c comes into contact with the inner end of the opening of the chute mouth guide 32.
When the bottle mouth 13c hits the chute mouth guide 32, the bottle mouth 13c repulsively rotates and drops while the bottle mouth 13c is directed upward while the bottle bottom 13a is directed downward, and the bottle mouth 13a is turned upward by being regulated by the passage wall of the chute 20. To be done. Plastic bottle with bottle mouth 13c turned upward
The 13 drops on the chute 20 and are supplied in line on the transport table 22. When dropping, the plastic bottle 13 has a moment of forward rotation, so when the bottle mouth 13c bounces, it tries to go forward but is stopped by the pop-out prevention guide 30.

In this way, the bottle mouth 13c hits the chute mouth guide 32 regardless of whether the bottle mouth 13c faces in the left or right direction, and the repulsion of the bottle mouth 13c can cause the bottle mouth 13c to face upward, and the center of gravity position when the bottle bounces Does not change much so shoot 20
The passage walls can be properly formed and can be aligned upward after passing through the chute 20. In addition, although the conventional hook-type device for tipping has to be enlarged in the vertical and horizontal directions, since this device has a large transfer amount and the rotation of the plastic bottle is in the horizontal direction, the size of the entire device is 1/3 to 1 Since the size is reduced to / 10, there is an advantage that it can be operated in a small space and can be produced at a low cost of 1/2 to 1/3 as compared with the conventional product.

[0016]

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, the bottle mouth of the plastic bottle hits the chute opening guide and bounces back, and the bottle mouth can be surely aligned and conveyed upward. Further, since the loaded state of the bottles being conveyed is checked by the stopper, the bottle bottom and the bottle shoulder can be dropped without hitting the chute port guide, and the bottle port can be reliably applied to the chute port guide. In this way, the bottle mouths can be surely aligned upward, so that the work in the next step can be smoothly performed.
