JPH0197103A - Power feed system for assembling line - Google Patents

Abstract

PURPOSE:To suppress the lowering of productivity, by dividing an assembling line into a plurality of assembling blocks, and by arranging special truck running feeders on the respective assembling blocks. CONSTITUTION:An assembling line L is divided into a first - a third assembling blocks B1-B3, and the respective assembling blocks B1-B3 are provided with a plurality of working stations S1-S9. On the respective assembling blocks B1-B3, feed rails r1-r3 connected to special truck running feeders F1-F3 are arranged. Respective trucks T1-T3 are provided with collector rings C1-C3 coming in sliding contact with the feed rails r1-r3. By controllers Co1-Co3, the working state of the feeders F1-F3 is controlled, and the running of the trucks T1-T3 is controlled. As a result, the lowering of productivity can be suppressed.

Description

[Detailed description of the invention] A6 Purpose of the invention (1) Industrial application field The present invention is directed to an assembly line, in particular, to a plurality of self-propelled trolleys, each carrying a member to be assembled thereon and causing the trolleys to travel. Regarding power supply systems for assembly lines.

(2) Prior Art Conventionally, this type of assembly line has been equipped with one power supply device for running the bogies (see Japanese Patent Laid-Open No. 155075/1983).

(3) Problems to be Solved by the Invention However, with the above configuration, if it becomes necessary to stop the carts only in a part of the assembly line, all the carts on the assembly line will have to be stopped. There is a problem of decreased sexuality.

An object of the present invention is to provide the above-mentioned power supply system that can solve the above-mentioned problems.

B1 Structure of the Invention (1) Means for Solving the Problems The present invention provides an assembly line in which a plurality of self-propelled carts are each loaded with members to be assembled and the carts run. Divide into multiple assembly blocks,
A feature is that each assembly block is provided with a dedicated power supply device for running the bogie.

(2) Effect With the above configuration, when it becomes necessary to stop the cart at a certain assembly block, the power supply device of that assembly block is deactivated, and the power supply devices of other assembly blocks are activated. Assembling work can be performed while the trolley is running while being held in place, thereby suppressing a decrease in productivity.

Further, since maintenance of each power supply device can be performed for each assembly block, the workability is good.

(3) In the drawings, for example, an automobile assembly line L has a plurality of assembly blocks B arranged in series, and in the illustrated example, first to third assembly blocks B.
+ ""'B divided into s, each assembly block 81
~B3 is a plurality of work stations Sl+ S2, S,
~S6, S7~S. Multiple self-propelled trolleys T
The I""' T3s each carry a vehicle body BO as a member to be assembled and travel on a track R from the first assembly block B1 to the third assembly block B3.

Each assembly block B l' = 83 is provided with first to third power supply devices FI""" F3 dedicated for running the bogie.Each power supply device F, -F3 is provided along the track R. The power supply rails r1 to r3 arranged therein are configured to be able to be supplied with power from the power supplies Esl to Es3 via the controllers Col to Co3.Each trolley T, ~T, has a bifurcated structure that slides into contact with the power supply rails r1 to r3. Equipped with collectors C+ to C3, each collector C8 to
Motors (not shown) provided in the trolleys T1 to T are energized via C3 to travel. Each assembly block B0. Between Bt and between BZ and 83, the motor is energized by the current collectors C1 to C3 straddling the refeed rails r 1 + r z and r 2 + r z. - Each controller Col to Co3 prepares the trolleys T1 to T3 for operation;
It has functions such as emergency stop.

In the above configuration, for example, when stopping the trolley T1 running on the first assembly block B, the first power supply device F,
The controller Col controls the power supply Esl and the supply rail r1.

If you keep the 2nd. In the third & Il standing blocks Bz and B3, assembly work can be performed while the trolleys Tz and Ty are running, thereby suppressing a decrease in productivity.

Further, since the maintenance of the first to third power supply devices Fl-F3 can be performed for each of the first to third &Il standing blocks B, to B3, the workability is good.

C0 Effects of the Invention According to the present invention, it is only necessary to deactivate the power supply device of the assembly block that needs to stop the bogie, so assembly work can be performed on other assembly blocks while the bogie is running. This makes it possible to suppress a decrease in productivity.

Further, since maintenance of each power supply device can be performed for each assembly block, the workability is good.
