Abstract

PURPOSE:To reduce the full length of the device by dividing the plural number of assorting wheels, provided in an assorting part of a carriage conveyor, into two groups of an upstream and a downstream so that articles can be carried out to both sides at the assorting part. CONSTITUTION:When the articles to be conveyed on a carriage conveyor 1 are taken out onto a carrying out conveyor 3 on other side or one side at an assorting part 2, a group of the plural number of assorting wheels 24 and the like, assigned to each of their carriage directions deviating leftward and rightward by about 45 deg. from the carriage direction of the conveyor 1, are projected upward by means of an air cylinder. Accordingly, a V belt 28 between a secondary shaft and each assorting wheel 24a, 24b is put in a strained condition, and each group of assorting wheels 24a or 24b is rotated with rotation of the driven shaft rotated by means of a driving shaft 29 through a V belt 32. Thus, articles are deflected to other side or one side and carried out by means of a group of rollers 42 rotated by the driving shaft 29 through a belt 44.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a conveying and sorting device for conveying a plurality of types of articles and sorting the articles by carrying them out at a predetermined position.

[Technical background of the invention]

Four items related to this type of device are:
The one shown in Japanese Patent No. 552 is known. This conventional device has a plurality of diagonally oriented wheels that can be retracted and retracted between the rollers of a roller conveyor, and when passing an item on the roller conveyor, the wheels are lowered and the item is moved sideways. When the container is to be transported to another location, the wheel group is raised.

[Problems with background technology]

By the way, in the above-mentioned conventional device, the delivery direction of the items is from one side, so when sorting a wide variety of items, the overall length of the device becomes long, and when connecting to other devices, the layout requires a lot of effort. The situation was harmonious, giving rise to constraints.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned points, and it is an object of the present invention to provide a conveyance and sorting device that can carry out articles in both directions.

[Summary of the invention]

The transport sorting device of the present invention includes a transport conveyor, a transport means provided in a section for the plurality of sorting parts of the transport conveyor and having the same transport direction as the transport conveyor, and a transport means that can appear and retract from the transport surface of the transport means. a plurality of sorting wheels provided and having a conveying direction that intersects with the conveying means;
In the sorting section, the items conveyed by the conveyor are carried out laterally from the conveyor by lifting the plurality of wheels to sort them,
The plurality of divisions provided in the above division divides the wheels into two groups, upstream and downstream, and the divisions in each group form the wheels so that they can be raised and lowered independently. The conveyance directions of the conveyors are directed to different sides of the conveyor.

In this case, as shown in Fig. 5, a long flat belt (51-, the upper running part of which is hung on the idle pulley 5253) is used. By turning K, each sorting section (2) is formed into a concave shape.
Alternatively, as shown in Figure 16, a short flat belt (
514) wrapped around the front and rear boops υG4) (to). Each sorting section (2) may be connected using a belt conveyor unit mallet. Furthermore, as shown in Fig. 5 and Fig. 6, For each sorting, a plurality of V-belts f57) arranged in parallel via front and rear pulleys (c) 5I may be used as the conveying means in section (2). In this case, each sorting The wheels may be disposed between each V-belt 1571.

In addition, in the above-mentioned embodiment, each sorting is provided in section (2), and the upstream sorting is provided with a group of wheels (24,) and the downstream sorting is provided with a group of wheels (244), but this is not limited to this. First, as shown in the off-line diagram, these may be provided apart from each other.
