Abstract

PURPOSE:To enable circulation through a single conveyor, in a conveyor for production facility, by arranging a pair of chains with an interval shorter than the long side but longer than the short side of A of a material to be carried and transferring the material to the return side while inverting by 90 deg.. CONSTITUTION:A pallet 1 carried on the upper carrying side of a carrying chain 2 is rotated by 90 deg. through a transfer means 3, then it is passed between the carrying chains 2 and lowered. Thereafter, the pallet 2 is rotated farther by 90 deg. and the long side of the pallet 1 is returned to the direction perpendicular to the carrying direction and mounted on the underside(return side) of the chain 2. Consequently, the pallet 1 is returned. By such arrangement, the pallet 1 can be circulated through a single conveyor.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a conveyor used in production equipment.

BACKGROUND OF THE INVENTION In recent years, transport conveyors have been required to achieve severe cost reductions in pursuit of production efficiency.

An example of the above-mentioned conventional conveyor will be described below with reference to the drawings.

FIG. 4 shows the configuration of a conventional conveyor.

In FIG. 4, 41 is a pallet, 42 is an upper conveyor, and 43 is a lower conveyor.

44 moves up and down with a lifter.

The operation of the transport conveyor configured as described above will be described below.

First, a pallet 41 is conveyed by a conveyor 42. The pallet 41 is transferred onto a lifter 44, and the lifter 44 carries the pallet 41 and lowers it to the same height as the conveyor 43. Next, the pallet 41 is transferred from the lifter 44 to the conveyor 43.
will be returned by.

Problem to be Solved by the Invention However, in the above configuration, in order to circulate the pallets 41, a conveyor 42, a conveyor 43, and a lifter 44 having two conveyors and a pallet transfer function are required.
However, there were problems in that the equipment was complicated and the cost was high.

In view of the above-mentioned problems, the present invention provides a conveyor that circulates pallets (objects to be conveyed) using one conveyor and transfer means with a simple structure.

Means for Solving the Problems In order to solve the above problems, the conveyor of the present invention has the following features:
A conveyor body consisting of a pair of left and right chains or belts arranged at an interval smaller than the width of the long side and larger than the width of the short side of the conveyed object, and the conveyed object is moved from the conveyance side to the return side of the conveyor body. The apparatus is equipped with a transfer means that transfers the conveyor by rotating it by 90 degrees, and the return side of the conveyor body is used for returning the conveyed object.

Function The present invention eliminates the need for a conveyor for returning pallets (objects to be transported) and transfers and loads pallets (objects to be transported) on the conveyor. It can be done.

EXAMPLE Hereinafter, a conveyor according to an example of the present invention will be described with reference to the drawings.

FIG. 1, FIG. 2, and FIG. 3 show the structure and operation of a conveyor in an embodiment of the present invention.

In FIGS. 1, 2, and 3, 1 is a pallet (transferred object), and 2 is a conveyor chain (conveyor body). The distance between the left and right pairs of chains 2a, 2a is smaller than the width (width on the long side) of the pallet 1 and larger than the width (width on the short side) of the pallet 1. Reference numeral 3 denotes a transfer means, which is composed of, for example, a vacuum pad.

The operation of the transport conveyor configured as described above will be explained with reference to FIGS. 1, 2, and 3.

First, as shown in FIG. 1, the pallet 1, which is conveyed on the upper side (transport side) of the conveyance chain 2, is rotated by 90 degrees and raised by the transfer means 3, as shown in FIG. next,
The transfer means 3 is lowered, and after the pallet 1 passes above the conveyance chain 2, it is rotated 90 degrees as shown in FIG. 3, placed on the return side of the conveyance chain 2, and the pallet 1 is returned.

As described above, according to this embodiment, by using the return side of the conveyance chain 2 for returning the pallet 1, the return conveyor can be eliminated. Note that it is also possible to configure the conveyor main body with a pair of left and right belts.

Effects of the Invention As described above, the present invention can simplify equipment and reduce costs by using the return side of the conveyor main body, which is composed of a pair of left and right chains or belts, for returning the conveyed object.
