JPH0585612A - Container-carrying conveyor - Google Patents

Abstract

PURPOSE:To provide a container-carrying conveyor capable of carrying a small- sized container and a large-sized container whose width is twice as large as that of the small-sized container, without meandering any of them. CONSTITUTION:Between drive roller rows 1 are disposed direction-regulating roller rows 2 with drive rollers 3 at one end of conveyor-center side and free rollers 5 at the other. Guides 6 are disposed on both the outsides of the conveyor.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container transporting conveyor capable of transporting a small container such as a drum and a large container having a width about twice that of the container without meandering.

[0002]

2. Description of the Related Art If the same roller conveyor is used to convey small containers such as drums in a 2 × 2 row, or if it is desired to convey a large container having a width of about 2 times, a large container is required. It is conceivable to use a wide roller conveyor adapted to the above, or to use narrow roller conveyors arranged in two rows adapted to a small container as shown in FIGS. However, in any case, the guide cannot be attached to the center side of the conveyor because it becomes a hindrance when conveying a large container. For this reason, when a small container is conveyed, meandering occurs and the mutual positional relationship is lost, which may cause trouble in the next step.

[0003]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art and provides a container transporting conveyor that can transport a large container and two rows of small containers without meandering. It was completed in.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. In the present invention, a portion of a central side of a conveyor is used as a driving roller between rows of driving rollers that provide a uniform driving force over the entire width of the conveyor. The arrangement is such that a direction regulating roller row having both side portions as free rollers is arranged, and guides are provided on both outer sides.

[0005]

The present invention will now be described in more detail with reference to the illustrated embodiments. 1 and 2 show a first embodiment of the present invention, in which 1 is a drive roller row and 2 is a direction regulating roller row. In this embodiment, the drive roller train 1 is composed of two drive rollers 3 and 3 arranged on both sides of the center line of the conveyor, and can provide a uniform drive force over the entire width of the conveyor. Further, the direction regulating roller row 2 has a short drive roller 4 at the center side of the conveyor and free rollers 5 not driven at both side portions.
Guides 6 are provided on both outer sides of such a conveyor.

As shown in FIG. 3, the diameter of the small container 7 is D
Then, the diameter of each roller is preferably D / 10 to D / 15. The appropriate pitch between the rollers is D / 5 to D / 3. Further, the pitch between the drive roller rows 1 and 1 is
It is preferable to set D / 2 to D, and if the above conditions are satisfied, the drive roller rows 1 can be arranged not every other row as in the embodiment but every two rows.

In the second embodiment shown in FIG. 4, the drive roller train 1 is constituted by one drive roller 8 extending over the entire width of the conveyor, and the direction regulating roller train 2 is also provided.
The central side of the conveyor is constituted by a common drive roller 9.

[0008]

When a large-sized container 10 as shown in FIG. 3 is conveyed by the container-conveying conveyor of the present invention constructed as described above, since a uniform driving force is applied to both sides of the center line of the conveyor, a large-sized container 10 can be obtained. The container 10 goes straight without any trouble.
Further, as shown in FIG. 2, when the small containers 7 are conveyed in two rows, the small containers 7 are given a linear movement force by the driving roller row 1, but in the direction regulating roller row 2, they are driven only by the center side of the conveyor. It receives a force and cannot receive a driving force on the outside, so it always receives an outward force. For this reason, the small container 7 advances along the guides 6 provided on both outsides of the conveyor, and can be conveyed without breaking the mutual positional relationship in two rows.

[0009]

As described above, since the container transporting conveyor of the present invention is capable of transporting both a large container and two rows of small containers without meandering, the conventional problems are encountered. As it has been resolved, the contribution to industrial development is extremely large.
