Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bottle conveyance device, which stands up a synthetic resin bottle from a lying position by utilizing the fall due to its own weight. It is conveyed in a predetermined direction.

[Conventional technology]

Conventionally, on a manufacturing line or a filling line, when a synthetic resin bottle in a recumbent position is raised up and transported in a predetermined direction, the container is placed in a chute with an intermittent loading device from a high position of 2 to 3 meters. The common method was to place the material into a screw or conveyor with blades, etc.

However, with such means, the processing capacity of each chute is limited to about 50 to 70 shots per minute, and the sensor for detecting the bottle, the actuator for operating the stopper, and its control device are required. I needed it.

[Problem that the invention attempts to solve]

In other words, with conventional devices of this type, the height position of the bottle must be changed, the processing capacity is poor, and many mechanisms must be installed, making the device complex and expensive. These disadvantages include the fact that they are easily damaged by contact between bodies, and it is difficult to transport long bottles or bottles with spherical bottoms upright.

The present invention was devised in order to solve the problems and dissatisfaction with the conventional examples described above, and its purpose is to make it possible to transport a bottle in a predetermined direction while standing up, which has been transported in a lying position. This is what I did.

[Means for solving problems]

Hereinafter, the present invention will be described with reference to drawings showing embodiments of the present invention.

The bottle conveyance device according to the present invention is for transporting a synthetic resin bottle 11 by standing it up by using the fall due to its own weight from a lying position. Upper conveyor 1 that runs
A pair of upper and lower conveyors 1 and 2 transports the bottles 11 on both conveyors 1 and 2, and the lower conveyor 2 carries the bottles 11 that had fallen from the upper conveyor 1 due to its own weight in an upright position. Top Skrillyu 3
and a lower screw 8 which cooperates with the upper screw 3 to transport the bottles 11 on the lower conveyor 2 while maintaining an upright position. It is composed of a screw and a regulating plate 10 provided on the other side of both conveyors 1 and 2 to prevent the bottles 11 from falling off the conveyors 1 and 2.

The upper screw 3 has its screw groove 7 tilted downward in the conveying direction on the conveyor side, and has a front half portion 5 facing the upper conveyor 1.
The groove width is slightly larger than the height and width of the body of the bottle 11, and the groove width is slightly larger than the thickness and width of the body of the bottle 11 in the rear half 6 facing the lower conveyor 2. It has a structure.

Similarly, the lower screw 8 has its screw groove 9
is tilted upward in the conveyance direction on the lower conveyor 2 side, and has a structure having a groove width equal to the groove width of the screw groove 7 in the rear half portion 6 of the upper screw 3.

Since the lower conveyor 2 carries the bottles 11 that fall from the upper conveyor 1 due to its own weight, it is a matter of course that it must be located directly below the end of the upper conveyor 1. It is necessary to install the upper screw 3 so that its running direction completely matches that of the upper conveyor 1 so that the bottles 11 on both conveyors 1 and 2 can be conveyed by rotationally driving the upper screw 3. .

Furthermore, the mutual height positional relationship between both conveyors 1 and 2 is based on the installation height position of the upper screw 3, when the bottle 11 in the lying position is placed on the upper screw 3.
The upper part of the body of the bottle 11 standing up on the lower conveyor 2 can be positioned in the screw groove 7 of the upper screw 3.

Further, the upper screw 3 and the lower screw 8 work together to hold the bottle 1 standing up on the lower conveyor 2.
1 can be transported while maintaining this upright position, the screw grooves 7 of the rear half 6 of the upper screw 3 and the screw grooves 9 of the lower screw 8 are perfectly aligned vertically. In addition, both screws 3 and 8 need to be rotated in opposite directions at the same rotational speed.

Similarly, it goes without saying that both screws 3 and 8 are arranged with their shaft portions 4 aligned with the running direction of both conveyors 1 and 2, that is, the conveyance direction.

[Effect]

Since the present invention has the above-described configuration, the bottles 11 that have been conveyed in a recumbent position by the running upper conveyor 1 are separated by a fixed interval by the screw groove 7 of the front half portion 5 of the upper screw 3. It will be opened and transported.

Bottle 11 transported by upper screw 3
When the conveyor 1 reaches the end of the run of the upper conveyor 1, it is reversed by its own weight in the direction of lowering its end in the conveying direction, assumes an upright position, and falls onto the lower conveyor 2 as it is.

At this time, since the screw groove 7 of the upper screw 3 is in a downwardly inclined position in the transport direction of the bottle 11, the above-described reversal change of the bottle 11 from the lying position to the standing position is caused by the slope of the screw groove 7. Therefore, the reversal of the bottle 11 from the lying posture to the standing posture can be achieved extremely smoothly and reliably.

When the bottle 11 falls onto the lower conveyor 2 in an upright position, the lower part of the body of the bottle 11 falls into the screw groove 9 of the lower screw 8, and the upper part falls into the screw groove 7 of the rear half 6 of the upper screw 3. Since the bottle body 11 is located inside the container, the bottle 11 in the upright position is held in the upright position by the upper and lower screws 3 and 8 at the upper and lower parts of the body and is transported together.

Note that a regulation plate 10 is provided on the side opposite to the side where the upper and lower screws 3 and 8 of the upper and lower conveyors 1 and 2 are arranged.
is provided, and the bottle 11 conveyed by both screws 3 and 8 is transported while being lightly pressed against this regulation plate 10, so that the bottle 11 does not come into contact with this regulation plate 10. It is desirable that the surface of the regulating plate 10 be extremely smooth and slippery to prevent scratches.

〔Example〕

In the illustrated embodiment, the bottle 11 in the lying position is
A plurality of pieces are conveyed by the upper conveyor 1 while making contact with each other with their bottoms on the downstream side in the conveying direction,
At part A, the screw grooves 7 of the upper screw 3 enter the front end, but the interval between the screw grooves 7 in the first half 5 gradually increases from the front end, so the adjacent bottles 11 enter the front end of the screw groove 7 of the upper screw 3. Appropriate spacing is adjusted to each other.

At the downstream end of the upper conveyor 1, the interval between the screw grooves 7 becomes smaller again, and at section C, the bottle 11 falls from the bottom due to its own weight and enters the screw groove 9 of the lower screw 8, but the screw 9 of the lower screw 8 Since the screw groove 7 of the upper screw 3 has a reverse thread, the bottom of the bottle 11 is received by the screw blades of the opposing lower screw 8 at this time, and does not turn over to a completely upright position.

Then, by the rotational movement of both screws 3 and 8, C
The bottle body 11 gradually rises from the part to the D part,
By increasing the distance between the screw grooves 7 and 9 from the E section to the F section, the distance between the upright bottles 11 is adjusted and sent to the subsequent process.

[Effect of idea]

As is clear from the above explanation, according to the bottle conveyance device according to the present invention, it is possible to accurately and smoothly convey bottles in a predetermined direction while changing them from a recumbent position to an upright position, and continuous conveyance is possible. As a result, the processing capacity is significantly improved, and there is no need to change the height position of the bottles or install many mechanisms such as sensors, making the equipment simpler and cheaper, and there is no need for bottles to be damaged due to contact with each other. Since both the upper and lower ends are held by screws in an upright position, it exhibits many excellent effects such as being able to transport long bottles and bottles with spherical bottoms in a stable upright position.
