Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an arrangement and supply device for containers filled with juices, soft drinks, etc.

(Prior Art) Generally, this type of container uses a material such as synthetic resin, and the containers that are molded by a container molding machine and sent must be lined up and then supplied to a liquid filling device. Containers shipped in boxes were manually lined up and supplied onto the supply conveyor of the liquid filling device.

(Problems to be Solved by the Invention) As described above, it is expensive to transport containers formed by a container molding machine in boxes, adjust the container's posture manually, and then feed it onto a conveyor. In addition, there were hygienic problems due to manual work, and there were problems in that productivity was impaired.

The present invention aims to solve the above-mentioned problems, and provides a container aligning and feeding device that can align and transfer containers formed by a container molding machine without human intervention. It is.

(Means for Solving the Problems) The present invention provides means for solving the above problems, and includes a plurality of eccentric rollers 5a in a casing having container P receiving hoppers 2 and 3. , 6a and a plurality of perfect circular rollers 5b, 6b.
roller conveyors 7 and 8 are provided in which roller conveyors 7 and 8 are arranged alternately at intervals approximately equal to the diameter of the containers P, and container fall prevention bars 10 are provided between the rollers except for the container take-out section, and Rollers 5a, 5
b, 6a, 6b in the axial direction at least 1
The gist of the invention is a container aligning and feeding device characterized by having a container guide bar 9 in a protruding manner.

(Function) Since the present invention has the above-described configuration, even if the orientation of the containers P thrown into the receiving hopper 2 from the container forming machine via the conveyor (not shown) is uneven, the containers P can be transferred by the roller conveyor 7. In the process of being pulsated in the vertical direction by a plurality of eccentric rollers 5a and perfect circular rollers 5b, one or more stripes protruding in the axial direction on the surface of each roller 5a, 5b are applied repeatedly. While being guided by a container guide bar (protrusion) and being transported laterally, the containers P are aligned so that their axes coincide with the axes of the rollers 5a and 5b, and then supplied to the next process.

If the container alignment and supply apparatus of the present invention is provided in two stages as in the embodiment described later, the containers can be aligned more reliably, and the containers can be aligned and supplied to the next process (for example, a liquid filling process).

(Example) The structure of the present invention will be explained with reference to an example shown in FIGS. 1 to 4.

In this embodiment, the container alignment and feeding device of the present invention is used in two ways.
In the figure, 1 is a casing that houses the entire apparatus, and a first receiving hopper 2 serves as an inlet for receiving containers from a container conveyor (not shown) sent from a container forming machine. A second container aligning and feeding device B is downstream of the first container aligning and feeding device A and communicates with the first container aligning and feeding device A via a second receiving hopper 3.

At the lower ends of the chute of the first hopper 2 and the second hopper 3, there are provided container pushing plates 4a and 4b which reciprocate in the direction of the arrow in conjunction with a drive device not shown in the drawings, and on the extrusion side thereof, an eccentric Rollers 5a, 6a
First and second roller conveyors 7 and 8 are provided in which round rollers 5b and 6b are alternately arranged at intervals approximately equal to the diameter of the container.

On the surface of each roller of the first and second roller conveyors 7 and 8, there is one or more stripes (two strips in this embodiment) for correcting the container posture along the axial direction.
A container guide bar 9 is provided in a protruding manner.

Between each roller 5a, 5b of the first roller conveyor 7, a container fall prevention bar 10 is fixedly installed parallel to the axis of each roller, except for the portion facing the second hopper 3.

Note that reference numeral 11 is a cold air duct that communicates with the inside of the casing 1 provided below the first hopper 2, and is used to cool down containers that are put into the hopper 2 when they have residual heat from the molding process. Therefore,
This can be omitted if the container is cooled during the transportation process from the molding machine and there is no residual heat.

From the container forming machine to the container conveyor (not shown)
Container P is put into the first receiving hopper 2 through
Although the postures (in the axial direction of the containers) are irregular, the first roller conveyor 7 is moved by the container pushing plate 4a.
In the process of being pushed upward and moving on the roller conveyor 7, vertical pulsations are repeatedly applied by the eccentric roller 5a and the perfect circular roller 5b, and
When being transferred laterally by the rotation of the rollers 5a and 5b, each container P is guided by the container guide bar 9, so that the axis of each container P is aligned with the rollers 5a and 5b.
Their postures are sequentially corrected so that they match the axis of the hopper 3, and they are aligned and sent to the second hopper 3.

Even if some irregularity remains in the posture of the containers sent from the second hopper 3 onto the second roller conveyor 8, the vertical pulsation caused by the eccentric roller 6a and the perfect circular roller 6b and correction by the container guide bar 9 are corrected. This action ensures that the axis of the container P is aligned with the axis of the rollers 6a and 6b, and the rollers 6 are aligned.
It falls downward from between a and 6b and is sent to the next process.

The second container alignment and supply device includes a number of movable alignment plates 12 below the second roller conveyor 8 for aligning containers falling from between the rollers 6a and 6b, and a number of fixed alignment plates 13 below the movable alignment plates 12. It is provided.

A large number of movable alignment plates 12 are arranged and suspended at predetermined intervals, and their lower ends are loosely fitted into elongated holes drilled in the common connection bar 14 via pins 17.
This connecting bar 14 is connected to a fluid cylinder 16 via an arm 15, and as the cylinder 16 expands and contracts, the connecting bar 14 swings, and in conjunction with this, the movable alignment plate 12 swings. It's summery.

By swinging the movable alignment plate 12, as shown in FIG. 4, only the containers P located at the lowest end of the containers P held between the movable alignment plates 12 can be sequentially dropped between the fixed alignment plates 13. .

The container P that has fallen between the fixed alignment plates 13 is moved to the sprocket wheel 1 driven by the motor 18.
9, the pusher 21 which is pushed out by any means such as a chain 20 sends it to the next process (for example, a filling process).

(Effect) According to the present invention, a plurality of eccentric rollers 5a, 6a and a plurality of perfect circular rollers 5b, 6 are provided in the casing 1 having the receiving hoppers 2, 3 for the container P.
roller conveyors 7 and 8 are provided in which roller conveyors 7 and 8 are arranged alternately at intervals approximately equal to the diameter of the containers P and are provided with container fall prevention bars 10 between the rollers except for the container take-out section, and Rollers 5a, 5
b, 6a, 6b in the axial direction at least 1
By protruding the container guide bar 9, the container formed by the container forming machine can be moved vertically and horizontally by eccentric rollers and perfect circular rollers during the transfer process without manual intervention. By the corrective action of the container guide bar, the axes of each container can be aligned so that they are parallel.

In addition, a bar to prevent containers from falling is provided between each roller except at the container takeout section, so containers are transferred smoothly without falling on the way.At the container takeout section, containers fall downward between the rollers, so each The containers are fed to the next step while their axial directions are kept parallel, which has the effect of providing an extremely efficient container alignment and feeding device.

Therefore, by directly connecting a container forming machine in the first stage and a filling machine in the second stage, the labor of transporting containers and manually aligning containers can be saved, and the process from forming containers to filling soft drinks can be performed hygienically in one factory. can be processed.
