BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for controlling a pitch during material supply in a continuous inspection and conditioning line in which a plurality of inspection or conditioning steps for various materials are continuously performed.

[0002]

2. Description of the Related Art In the manufacturing process of various materials, there are many types of inspection processes such as material inspection and defect detection, and polishing processes such as polishing and cutting. Work that combines the adjustment process is performed. In order to improve the efficiency of such work, supply equipment and payout equipment are installed before and after each inspection device or adjustment device to configure inspection adjustment equipment, and pass the required inspection adjustment equipment according to the material. Is done.

In addition to the single inspection device and the adjusting device, there are a plurality of inspection devices, a plurality of adjusting devices, or a combination of the inspection device and the adjusting device which are continuously arranged. In the book, these are collectively referred to as the inspection and conditioning device. And what provided the material supply apparatus and the payout apparatus before and behind that is called inspection and adjustment equipment. In addition, a line in which a plurality of these inspection and adjustment facilities are arranged in succession is called a continuous inspection and adjustment line.

An example of such a continuous inspection and conditioning line is shown in FIG.
Shown in. The material is first supplied to the material supplying device 1 of the inspection and conditioning equipment A, and then conveyed through the inspection and conditioning device 2 and the dispensing device 3 in that order for processing. Then, the material supply device 1 of the inspection and conditioning equipment B,
The inspection and conditioning device 2 and the dispensing device 3 are conveyed, and further, the material supplying device 1, the inspection and conditioning device 2 and the dispensing device 3 of the inspection and conditioning facility C are conveyed, and the respective processes are performed. Figure 2
In the inspection and conditioning equipment B, there are two types of inspection and conditioning devices 2, and a reject material unloading device 4 is provided on the downstream side of the dispensing device 3.

By the way, the processing capacities of the respective inspection and conditioning devices 2 are different, and the type and size of the materials that are successively supplied and sequentially conveyed may vary, so that the processing capacity of the entire line is the most efficient. The optimum sequence pitch setting control is performed by the sequencer for the purpose of demonstrating the above. That is, in each inspection and adjustment equipment A, B, C,
The minimum time of the material supply time interval is set and controlled so that the material supply, inspection and adjustment, and delivery work can be performed without the preceding material and the following material interfering with each other.

Each inspection and adjustment equipment A of the continuous inspection and adjustment line,
In B and C, pitch control is performed as follows, for example, when inspection or refinement is performed in the length direction of the material. Supply time Ts, inspection and refining time Tk
, And the payout required time Te are calculated from the material length L and the transport speed V of each equipment determined from the size information of the material, and for each equipment A, B, C, Ts = (L / α1 V ) + K1 (1) Tk = (L / V) + K2 (2) Te = (L / α2 V) + K3 (3) Here, Ts: time required for material supply; time from the start of cutting and transferring from the material supplying device to the conveying device until the time when cutting and transferring of the next material can be started Tk: time required for inspection and finishing; Time from the start of entering the inspection and conditioning device until the next material can start entering Te: time required for delivery: after the preceding material has entered the delivery position, the transfer operation of delivery is completed, Time until line material can enter K1: Time required for cutting and transferring from the material feeding device to the transportation device (kicker, transfer, walking beam, etc.) K2: Time required for transportation by the length of the inspection and conditioning device K3: Transport Time required to cut and transfer from the device to the dispensing device L: Material length V: Material transport speed when passing through the inspection and conditioning device α1: Lead rate α2 of transport speed for closing the material gap between the preceding material and the next material: To secure the transfer transfer time K3 It is the lead rate of the transport speed.

Next, the maximum value Tm is obtained by comparing these three values. The obtained Tm is registered as the shortest pitch of the inspection and conditioning equipment. Then, the respective inspection and adjustment equipments A, B, in the continuous inspection and adjustment line as shown in FIG.
Among the shortest pitches Tma, Tmb, and Tmc of C, the maximum value is the shortest pitch P of the material to be fed to the first inspection and conditioning equipment A so that the preceding material and the following material do not interfere in the line. Is set.

In the conventional pitch control, the above-described arithmetic processing is performed in the sequencer, and a separate arithmetic program is used for each of the inspection and conditioning equipment A, B, C. As an example of the flow, as shown in FIG. 4, for the inspection and conditioning equipment A, the supply time Tsa, the inspection and conditioning time Tka, and the delivery time Tea are controlled by the program A.
Is calculated to determine the maximum time Tma, and the inspection and conditioning equipment B and C are also programmed B
And C to determine the maximum times Tmb and Tmc. Then, Tma, Tmb, and Tmc were compared, and the maximum value Tm was set as the shortest pitch, and this was set as the pitch P for the first inspection and conditioning equipment A.

[0009]

In such a conventional inter-pitch control in a continuous inspection adjusting line, it is necessary to incorporate a calculation program of the shortest pitch in each of a plurality of inspection adjusting facilities when designing a sequence program. However, there has been a problem that the volume of programs for the sequencer becomes large as the number of inspection and adjustment facilities to be continuously performed increases, resulting in an increase in cost and calculation processing time.

The present invention calculates the shortest pitch of each equipment in a continuous inspection and adjustment line in which a plurality of inspection and adjustment equipments in which supply, inspection and adjustment and delivery are performed in sequence are arranged.
An object of the present invention is to provide a method and apparatus for controlling the cutout timing without increasing the volume of the program.

For example, in the case of inspecting and refining a material having a length L in a length direction in a continuous inspection and refining line as shown in FIG.
Each inspection and refinement facility A, according to the common program as shown in FIG. 3, which uses the equations (1), (2) and (3),
For B and C, the required material supply time Ts, the inspection required time Tk, and the required delivery time Te are calculated. Then, from these times, the shortest pitch of one inspection and conditioning facility is obtained. As for the possible timing at which the next material can be supplied to the material supplying device 1 of the continuous inspection and conditioning line as shown in the example of FIG. 2, for example, the inspection and conditioning equipment A, the preceding material does not exist in the material supply operation range. This is at the time, that is, after the elapse of the material supply required time Tsa.

The material supply time Ts,
The inspection and finishing time Tk and the payout time Te are (1),
The locus of the material is calculated by the equations (2) and (3), and is shown by the solid line in FIG.

As a conventional example, when the flow of FIG. 4 is carried out, a program of about 8K steps is required only for the inter-pitch calculation processing, and the processing speed is 50 ms / scan or more. Now, the inter-pitch control is only the interface program, the overall load is reduced, and the processing speed can be maintained at 30 ms / scan. The sequencer load factor is 90 in the conventional example.
