Abstract

PURPOSE:To simplify a parts feed control system, reduce the redundancy of a line and effectually cope with the change in the type of a product or in the quantity of production, by providing a parts feeder, a parts conveyor and a product collector. CONSTITUTION:The plural vibration feeders 2 of the parts collector of an automatic assembly system correspond to parts which constitute a product. Over a turntable 3, pallets 5, on each of which wall the parts necessary for the single product are arranged, are sequentially carried on a conveyor 6 and taken in by the conveyors 7 of assembly units corresponding to respective products for which assembly procedures are programmed depending on the constructions of the respective products. Each robot 1 is programmed to perform plural working processes. The assembled products are transferred onto a product collection conveyor 11 by a transfer unit 10. According to this constitution, a parts feed control system is simplified, and the change in the quantity of production or the like is effectually coped with.

In general, it is difficult to automate the assembly work of products that have a wide variety of structures and shapes, and that have the possibility of model changes, using conventional specialized automatic machines. This method is widely used.

In recent years, the development of automatic machines with a large degree of freedom, such as industrial robots, has progressed, and the automatic assembly system shown in Figure 1 has appeared, which has replaced conventional conveyor line workers to some extent. Such a system had the following drawbacks.

That is, the industrial robot 1 requires a parts alignment and supply device 2 such as a vibrating feeder because it is difficult to handle bulk parts. In order to replenish parts, a parts supply system such as a human system or an automatic guided vehicle will be required along the entire length of the long assembly line. Or, because the work process is broken down into unit work and carried out along the conveyor as work stations, an abnormality at a work station midway through can easily cause the entire line to stop.

When producing a mixture of different types of products, it is necessary to prepare programs for each model and vibratory feeders for each part type at all work stations. Furthermore, some models have unnecessary work stations, increasing line redundancy. In addition, in response to fluctuations in production volume, the line length is long, so in the case of small-volume production, there are problems such as an increase in the minimum number of controls required to meet profitability.
