Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a component selection instruction device on a production line, and more particularly to an instruction device for visually and aurally indicating parts to be assembled in a multi-product mixed production line.

Conventionally, when producing many types of products on one line, in order to prevent parts assembly errors, sensors installed on the line read the product type and indicate the corresponding parts to be assembled using lamps, etc. A so-called parts selection instruction device was used.

However, since such an instruction device only provides visual instructions by holding a lamp or the like to the sheep, the operator often overlooks the problem and makes a mistake in assembling parts.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, it is an object of the present invention to provide a parts selection instruction device that can reduce parts assembly errors as much as possible in a multi-product mixed production line.

The purpose of this is to use a sensor that reads the type of product flowing on the line, and a control device that determines the parts to be assembled to the product based on the signal from the sensor and outputs assembly instructions in accordance with the assembly order. This is achieved by a parts selection instructing device that includes a visual indicator that visually displays a parts display based on a signal from the control device, and a speaker that also provides an auditory display.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a layout diagram showing the component configuration of a component selection instruction device according to the present invention. In the figure, 1 is a conveyor, 2 is a product placed on conveyor 1, and product 2 is a conveyor 1.
It flows from right to left like arrow A above. In front of the product 2, there is a parts yard 3 beside the conveyor 1.
A so-called parts assembly line is provided, where workers 4 are placed.

However, this parts selection and instruction device is installed on the parts assembly line. That is, 5 is a sensor installed on the conveyor 1, 6 is a lamp installed in each sorting box on the parts yard 3, 7 is a speaker installed near the worker 4, and these are connected to the control device 8. Each is connected by an electrical signal line. Further, a code 9 indicating the product type is pasted on the product 2.

Now, as the product 2 flows on the conveyor 1 in the direction of arrow A, the sensor 5 reads the code 9 on the product 2 and sends the signal to the control device 8. Based on this, the parts to be assembled to the product 2 are determined, and assembly instructions are outputted to the lamp 6 and the speaker 7 in accordance with the assembly order.As a result, the lamp 6 lights up, and the speaker 7 outputs a message indicating the characteristics of the parts. For example, a color-specific "black" sound is emitted, and the worker 4 can visually and auditorily know which part to assemble next.

As shown in FIG. 2, the control device 8 includes an input/output section (Ilo) 10, a central processing unit (CPU) 11, a memory section 12, and an audio output board 13. A correspondence table between product types and parts to be assembled is set in advance in the memory 12, and parts to be assembled to the product 2 are determined based on this comparison. Note that a sensor 5 and a lamp 6 are connected to the l1010, and a speaker 7 is connected to the audio output board 13.

Hereinafter, a specific application example of this component selection instruction device will be explained based on FIG. 3. Note that the same components as those shown in FIG. 1 are given the same reference numerals.

In FIG. 3, I, II, I[[ are the first . Second. Third
At the parts yard, similar parts are sorted into [I, R...], (A, B...), (1, 2...].And now, the parts on conveyor 1 are sorted. The product 2
When the product 2 is flown, the type of the product 2 is determined by the parts selection and instruction device, and first, the lamp 6 on the first parts yard I is lit to indicate, for example, the part [mouth]. At the same time, a sound called [mouth] is emitted from the speaker 7, and based on this, the worker 4 assembles the part [mouth] of the product 2ζ. During this time, the product 2 is flowing on the conveyor 1 at a predetermined speed, and after a predetermined time has elapsed, the lamp 6 above the second parts yard turns on, indicating, for example, the part CD), and at the same time the speaker 7 The sound [D] is emitted from [D], and after a predetermined period of time, the parts [D] in the third parts yard m are also emitted.
2] is instructed from the lamp 6 and speaker 7I.

The assembly time of each component is inputted in advance to the control device 8, and instructions are given to the lamp 6 and the speaker 7 at a predetermined exit timing based on the conveyor speed work position 14, etc. .

FIG. 4 shows an example of the output timing, and it is clear that the lamps marked ``Tado'' are sequentially turned on (ON), and a sound is emitted (ON) in accordance with the lighting.

Note that as a sensor for reading the type of product 2, various optical character reading devices, a barcode reader for reading barcodes, etc. are used. Further, instead of the lamp display, a light emitting diode, liquid crystal, etc. may be used.

As explained above in detail, the parts selection instruction device of the present invention is designed to issue two different output signals, light and sound, simultaneously to instruct the parts to be assembled. The operator now knows through sight and hearing which part to assemble next, which has the effect of significantly reducing parts assembly errors compared to conventional single instructions.
