Abstract

PURPOSE:To reduce the time of no load operation of a conveyor device in which a plurality of conveyors are laid in series, by providing such an arrangement that the topmost level conveyor is driven in association with the open and close operation of a hopper gate, and low level conveyors are driven in response to a signal from a conveyed material detector set on a conveyor just thereabove. CONSTITUTION:The most upstream conveyor 1 is started and a gate 4 is opened, and materials to be transferred are conveyed from a hopper 5. A tilt switch 6 set on the most upstream conveyor 1 detects the materials and delivers a detection signal which starts a conveyor 2. When a tilt switch 7 is actuated, a conveyor 3 is started. When no signals are issued from the tilt switches 6, 7, the downstream conveyors 2, 3 are rested. With this arrangement, the time of no load operation is reduced, and energy saving may be made.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a conveyor system (-), and particularly relates to a conveyor system with an improved automatic control function for conveyor operation.

[Technical background of the invention and its problems]

Conventionally, when several conveyors were connected in series, they were started in sequence from the downstream side, and the conveyor began transmitting the goods only after the most upstream conveyor had finished starting.

In this case, there is a problem in that the conveyor that is started for the first time is operated for a long time in an unloaded state.

f (IJ, start the conveyor on the most downstream side, and after the start is completed, start the conveyors on the upstream side sequentially. After the start of the conveyor with the lowest accent is completed, start the middle conveyor, and after the start is completed, start the conveyor on the most upstream side. When the most upstream conveyor was started, the gate was opened and the cargo began to be removed from the hopper.

Therefore, the no-load operation time of the most downstream conveyor was extremely long. Moreover, once started, each conveyor operates continuously until the entire work is completed, so it is difficult to avoid long periods of no-load operation of each conveyor.

[Purpose of the invention]

The present invention has been made in view of the above points, and an object of the present invention is to provide a conveyor device that reduces the no-load operation time of the conveyor and has the same energy consumption efficiency.

[Summary of the invention]

In order to achieve such an object, the present invention provides a conveyor device in which a plurality of conveyors are successively arranged from the upstream side where the gate of the hopper containing the transported object is arranged to the downstream side, at least the most downstream side. All conveyors other than the above are equipped with a detection device that detects when the conveyed object passes through a predetermined position on each conveyor itself, and the conveyor on the most upstream side starts and stops in conjunction with the opening and closing of the gate, and the other conveyors are adjacent to each other. Detection signal from the detection device on the upstream conveyor? It is characterized in that it starts to start sequentially from - to the upstream side and stops sequentially from the upstream side in conjunction with the closing of the gate nII.

[Embodiments of the invention]

An embodiment of the present invention will be described below. In Figure 1,
Conveyors 1.2.3 are arranged in sequence from the upstream side to the downstream side. A hopper 4 containing objects to be conveyed is arranged at the most upstream end of the most upstream conveyor l, and a gate 5
The transport of the transported object is started and stopped by opening and closing. Further, the conveyor 1-12 is provided with a tilt switch 6°7 at a predetermined position.

In this configuration (U), first start the most upstream conveyor 1,
When the start is completed, the gate 4 is opened and the unloading of the cargo from the hopper 5 is started. A tilt switch 6 installed in the middle of the most upstream conveyor 1 (when it detects that a load has arrived from the second side, the middle conveyor 2 is started.

Furthermore, C-1, a tilt switch 7 installed in the middle of this conveyor 2 detects the arrival of the baggage from the second position, and sequentially starts the downstream conveyors.

When the gate 4 closes, the conveyor l on the most upstream side stops.

At this time, if the tilt switch 6 does not detect the passage of the conveyed object, the intermediate conveyor 2 also stops at the same time.

Therefore, each conveyor starts a predetermined time (second start) before the cargo starts flowing, and stops when no objects to be conveyed pass, so the no-load operation time can be significantly reduced, and the energy saving effect is extremely large.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to provide a conveyor device that reduces the no-load operation time of the conveyor and improves energy consumption efficiency.
