Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveyor device for transporting articles, and more particularly to a conveyor device that can be opened and closed without obstructing a working path for people or transport vehicles that intersect on a plane.

Conventionally, conveyor devices, both roller and belt types, have been used as an effective means of conveying articles arbitrarily and continuously, but they occupy the installation floor continuously, and therefore have a large impact on the traffic of workers and transport vehicles. This has resulted in a deterioration of the associated work environment and a disregard for humanity.

The present invention eliminates such drawbacks and makes it possible to open and close this part of the conveyor device that intersects with the working path.The conveyor is connected only when conveying articles and is normally open, so that workers can The goal is to ensure the passage of traffic such as

According to the present invention, the primary side conveyor is equipped with a sensor for detecting article conveyance and a stopper near one end thereof, and one end of each of the screw thread, the universal joint for power transmission, and the air cylinder is connected to the first conveyor.
Connected to the next conveyor. It is equipped with a swingable communication conveyor, a sensor group provided on the communication conveyor for detecting the presence or absence of an article fixed substantially outside an article conveyance path, and a receiving sensor for detecting passage of an article from the primary conveyor. There is obtained a conveyor device characterized in that it is comprised of a secondary conveyor that connects the communication conveyor, and a mat-like switch installed in a passage formed when the communication conveyor is open.

The figure is an explanatory diagram of the present invention. 1 is a sensor provided on the primary conveyor 2 to detect the passage of articles, and 3 is a sensor provided near the end of the primary conveyor 2, which is used only in specific cases. This is a stopper that protrudes from the lower surface of the article conveyance path using an air cylinder or the like (not shown) to prevent the article from being transferred. 4 is a communication conveyor that can be swung by an air cylinder 5 via a screw thread 6, and 7 is a universal joint that transmits the power for conveyance from the primary conveyor 2 to the communication conveyor 4. 8, 8' and 9, 9' are sensor groups for detecting articles moving on the communication conveyor 4, and 11 is a receiving sensor 12 for detecting passage of articles.
This is a secondary conveyor having a

Reference numeral 13 denotes a pine-shaped switch installed in the worker or carrier passage 14 and having a predetermined length from the intersection point with the communication conveyor 4 in both directions.

Next, the operation of the conveyor device according to the present invention will be explained.

The communication conveyor 4 operates when conveying articles and delivers them to the secondary conveyor 12. However, in a conveyor system where there is a large flow of articles, when using the passage, that is, when a worker or a transport vehicle etc. A system in which the conveyor is opened only when it is desired to cross can be realized by simply changing the control flow for the conveyor in the present invention. The figure therefore shows the normal state.

When an article is flowing, the sensor 1 detects this, and if there are no workers or transport vehicles crossing the conveyor, that is, if the pine-shaped switch 13 is in the open state, the communication conveyor 4 is activated immediately and the secondary It is connected to the side conveyor 11 to transfer articles.

When it is confirmed by the sensor groups 8, 8', 9, and 9' that no article is on the communication conveyor 4, and when the receiving sensor 12 detects the passage of the article, the normal state is restored. In other situations, sensor 1
When there is a worker, a transport vehicle, etc. crossing the conveyor at the same time, and the pine-like switch 13 is in the operating state, the stopper 3 is operated to prevent the article from being transferred. When a person, a transport vehicle, etc. passes and the pine switch 13 is opened, the communication conveyor 4 is operated, and at the same time the connection to the secondary conveyor 11 is completed, the stopper 3 also starts transferring the stocked items from the conveyance road surface. . After the article has passed, the communication conveyor 4 returns to its normal state when the same state as described above is reached.

In the illustrated embodiment of the present invention, a roller conveyor is assumed, but a belt conveyor may also be used, and other means may be used as long as the power can be transmitted to the communication conveyor 4 only when the communication conveyor 4 is in operation. , is not limited to the universal joint 7.

According to the present invention, when a work passage and a conveyor device intersect, there is no need for expensive installation work such as creating a three-dimensional intersection, and even a flat installation does not obstruct the passage of workers. Furthermore, it is also possible to provide an external worker priority button to forcibly suspend the article transfer operation, which has a great effect on improving the work environment and work efficiency.
