Description

[Detailed Description of the Invention] [Summary] When an automatic component insertion device mounts a component on a processed product, when the automatic component insertion device replaces a missing component with an extra component among the prepared components, the most frequently used component is replaced with a surplus component. By instructing the replacement of channels that store parts with a small number of parts, the number of channel replacements is reduced and the usage efficiency of the automatic parts insertion device is increased.

[Industrial application field]

The present invention relates to an automatic component insertion device that mounts components at predetermined positions on a processed product, and particularly for efficient replacement of component supply channels for multiple types of processed products that use different types of components. This invention relates to a channel exchange method for an automatic component insertion device.

In recent years, with the advancement of automation in the manufacture of various communication devices and electronic devices, various automated devices have come into use, and one of these automated devices is an automatic component insertion device.

This automatic component insertion device is used, for example, to automatically mount components on a so-called printed board unit, that is, a processed product, on which various components necessary for constructing communication equipment and electronic equipment are mounted. A plurality of types of parts are stored in separate channels, and a plurality of these channels are mounted.By selecting this channel, the required part is taken out and mounted at a predetermined position on the processed product.

However, these processed products are not only of the same type being supplied to the automatic parts insertion device; in order to have various functions, different types of parts are supplied at random due to the circumstances of the manufacturing site. Ru.

In this case, when replacing the channel, it is necessary that the processing efficiency of the automatic component insertion device not be reduced.

[Conventional technology]

FIG. 3 is a block diagram showing an example of a conventional automatic component insertion device, and FIG. 4 is a diagram illustrating the operation of FIG. 3.

The processor 1 reads a program stored in the ROM 3 and operates. The processor 1 controls the control circuit 8 via the interface circuit 6, and causes the automatic component insertion section 15 to report the channel numbers of channels 10 to 14 and, for example, component codes a to e, and stores them in the RAM 2.

Subsequently, the control circuit 8 controls the reading section 7 to read the code indicating the figure number of the processed product entering the automatic component insertion section 15. The control circuit 8 sends this code to the processor 1 via the interface circuit 6, and the processor 1 stores this code in the RAM.
Issue the successor stored in 2.

Based on this read code, the processor 1 reads the part code used by the processed product from the part file 5 via the file control circuit 4, stores it in the RAM 2, and reads the part code a set in the part automatic insertion section 15. -e
Verify with.

For example, as shown in FIG. 4, the part code required for the processed product 16 initially set in the automatic parts insertion section 15 is a,
b, f, it turns out that part code f is insufficient and channels 12 to 14 are unnecessary.

Therefore, the processor 1 instructs the control circuit 8 via the interface circuit 6 to display on the display section 9 the part code f to be set in exchange for the removable channel numbers 12-14.

Here, when the operator exchanges any channel among channels 12 to 14 with the channel storing the part with part code f, and reports this to the processor 1 via the control circuit 8,
Processor 1 updates the exchange channel number and part code in RAM 2.

Next, when the processed product 17 arrives, the code of the processed product 17 is read by the reading unit 7, and in the same manner as described above, the processor 1 detects that part codes a, c, and g are required, and the part to be set. The code g is displayed on the display section 9. If the channel 12 has been replaced for the processed product 16, the display section 9 will display that the part code C is also insufficient.

When the processed product 18 comes next, it has part codes a and b.

e is required. When the processed products are 16 and 17, if the replaced channels are both 13, there is no missing part code display, but if the processed product is 16 and the channel 14 is replaced,
When channel 11 is being replaced for workpiece 17, shortages of part codes b and e are displayed.

[Problem that the invention seeks to solve]

As mentioned above, conventionally, when instructing channel exchange, exchangeable channel numbers are displayed, but the operator can decide which channel number to exchange. Therefore, depending on the replaced channel number, the number of missing part codes for the next processed product will vary, and the channel that was previously removed will often have to be set again, which increases the number of man-hours required for channel replacement. There is a problem in that the operating rate of the insertion device decreases.

In view of these problems, the present invention aims to provide a channel replacement method for an automatic component insertion device that can reduce the number of man-hours required for channel replacement and prevent a decrease in the operating rate of the automatic component insertion device.

[Means for solving problems]

FIG. 1 is a block diagram of a circuit showing one embodiment of the present invention.

FIG. 1 shows a ranking file 20 in which the results of calculating the frequency of use of each component code during a certain period are stored in advance in the parts automatic insertion device shown in FIG.
A file control circuit 19 for controlling reading is added.

[Effect]

In the above-described configuration, the processor 1 is first set in the parts automatic insertion device during a certain period of time, for example, on a daily or weekly basis, based on information input by an operator (input via a keyboard not shown). Based on the type of processed product and the number of products produced (calculate the frequency of use for each part code from the parts configuration).

Then, the file control circuit 19 is activated and the calculation results are stored in the ranking file 20.

Then, the required part code is detected based on the code of the incoming workpiece, and based on the usage frequency obtained from this file 20, the most frequently used part code is selected from among the channels sent to the automatic part insertion device. Instruct the channel number that stores a small part code and have it replaced. At the same time, each time the component insertion for the same processed product is completed, the component usage frequency in the file 20 is recalculated and updated from the component code and its quantity used for the processed product.

As explained above, according to the present invention, the operator is instructed to specify the channel number that stores the component with the least frequently used component code, which reduces the frequency of channel replacement and makes it easier to use the automatic component insertion device. Efficiency can be increased.

〔Example〕

FIG. 2 is a diagram illustrating the contents of the ranking file 20 shown in FIG. 1.

In FIG. 1, the channel numbers set in the automatic component insertion section 15 are Iθ to 4, and the component codes are a-e.
It is assumed that the processed product 16 is supplied as shown in FIG.

Similarly to FIG. 3, when the processor 1 detects that the part code r is insufficient, it refers to the ranking file 20 via the file control circuit 19.

As shown in FIG. 2(a), the ranking file 20 stores the results of calculating the frequency of use for each part code from the parts configuration based on the type of processed product and the number of production for -1 days in advance, for example. .

That is, for example, parts codes up to a w i are used, with part code a having the highest usage frequency and part code i having the lowest usage frequency. The processor 1 instructs the control circuit 8 via the interface circuit 6 to replace the channel 14 and replace the component code f because the component code e stored in the channel 14 of the automatic component insertion section 15 is the least frequently used.
The display section 9 will display a message to set the .

When the component insertion of the processed product 16 is completed, the processor 1 receives the component code a from the control circuit 8 via the interface circuit 6.
, b, and f are reported, and the frequency of use of part codes a, b, and f is recalculated as shown by the solid line in FIG. 2 (bl), and the contents of the ranking file 20 are updated via the file control circuit 19. .

Next, when the processor 1 detects that the component code g is missing from the code of the processed product 17, the component code set in the automatic component insertion section 15 is a.

b, c, d, and f, and since component code f has the lowest frequency of component usage in the ranking file 20, an instruction is given to replace the channel 14 and set component code g.

When the component insertion of the processed product 17 is completed, the processor 1 receives the component code a from the control circuit 8 via the interface circuit 6.
, c, and g are reported, and the frequency of use of part codes - a, c, and g is recalculated as shown by the dotted line in Figure 2 (bl), and the contents of the ranking file 20 are updated via the file control circuit 19. do.

Next, when it is detected that the component code e is insufficient from the code of the processed product 18, the component codes a, b, and c currently set in the automatic component insertion section 15 are inserted.

Among d and g, the exchange of channel 12 in which part code C, which has the lowest usage rate, is stored and the set of part code e are displayed.

〔Effect of the invention〕

As explained above, since the present invention replaces channels that store parts that are used less frequently, channels that store parts that are used less frequently are not left in the automatic parts insertion section. The number of channel exchanges is reduced,
The operating rate of the automatic component insertion device can also be improved.
