Step 33 of replenishing components is a step in which the component replenishment work is completed by the manual operation of the keys on the operation panel described above, and an instruction is given to return to the component mounting operation.

Regarding the component mounting method configured as above.

The operation will be explained below.

The control device 13 is in charge of controlling the overall operation, and the parts cassette 1 is moved in the moving process 21 according to a component mounting instruction program (hereinafter referred to as the mounting program) stored therein.
7, the mounting head 16 takes out the parts from the parts cassette 17 in the take-out step 22, moves the parts cassette 17 in the moving step 23, detects that the parts in the parts cassette 17 is empty in the parts detection step 24, and When the parts are gone, the operation moves to the input stage 28 or lower. On the other hand, if there are parts, the parts cassette 17 is moved in the movement process 26, the mounting head 16 mounts the parts in the mounting process 26, and it is determined in the judgment process 27 whether to end the mounting process or continue from the movement process 21. to decide. In addition, the judgment step 24
In the input process 28, one operator issues an instruction to proceed to the next process by inputting a key from the operation panel, and in the display process 29,
The out-of-part parts cassette number is displayed on the main operation panel 14, the operator confirms this, and the input process starts at 30. In the moving step 31, the parts cassette obtained in the display step 29 is moved to a position where the replacement work can be easily performed using key manual power, and in the replacing step 32, the parts cassette with no parts is replaced with a parts cassette filled with parts, In the input process 33, the operator manually instructs from the operation panel that the replenishment of parts is completed.

Here, during one mounting operation, the moving step 21°23.2
As shown in Fig. 3, the mounting head 16 has 10 mounting parts, which are rotated by 36"C. 18 is the component extraction position, and 19 is the component detection position. ,
2o is the component mounting position. Therefore, at the same time as the mounting process 26, the component removal process 22, which is six times ahead, is performed. Therefore, the parts cassette may be moved many times while one piece is being mounted.

Furthermore, another conventional example will be explained. FIG. 2 is a conceptual diagram of an electronic component automatic mounting machine, and FIG. 5 is a flowchart of a conventional mounting method. In FIG. 6, 34 is the parts cassette 17
35 is a process for the mounting head 16 to take out components; 36 is a process for detecting component shortage; 37 is a process for mounting components by the mounting head 16; 38 is a process for determining whether to replenish components; 39 is a process for determining whether to replenish components. 40 is a step in which the control device 13 stores the hoodie set with missing parts; 41 is a step in which the parts cassette is changed to the next one specified in the mounting program of the control device 13; 42 is 28.4
3 is 29.44 is 30.46 is 31.46 is 32.47
is the same step as 33, and 48 is a step of determining whether the parts replenishment process has been completed.

Regarding the component mounting method configured as above.

The operation will be explained below. The operation is the same as that of the conventional example, but since the configuration of the mounting head 16 is not rotary, the parts cassette moves only once during the mounting of one part. Here, we have already identified patent application 60-62.
As proposed in the specification of No. 846, when it is determined that a part is out of stock in the one-part detection step 36, in the changing step 41, the part cassette that has run out is replaced with a spare parts cassette, thereby detecting the out-of-part part. Even if something happens, the implementation process can continue.

Furthermore, in the parts replenishment processes 42 to 48, unlike the conventional example described above, a plurality of parts cassettes are to be replenished with one part, so in the judgment step 48 it is checked whether all parts cassettes of out-of-parts cassettes have been replaced.

Further, a storage step 40 is provided for storing a plurality of out-of-parts cassettes.

Even if this is done, the parts cassette will have moved by the time it is detected that a part is out, making it difficult for the operator to directly visually detect the out-of-part parts cassette.Confirm on the operation panel and replace the parts cassette. The parts cassette must be moved to a position where work can be done easily.

In addition, in the second conventional example, the mounting head is not rotary, so if it stops immediately when a part runs out, the operator can understand that the parts cassette at the position where the mounting head takes out the parts is out of parts, and remove the parts cassette. It is also possible to exchange. Furthermore, if it is difficult to replace the parts cassette due to the mechanism of the mounting head depending on the type of parts, the parts cassette will be moved before the replacement work is performed. However, in this case, it is possible to continue the mounting process, and since the parts cassettes that are out of stock are replaced at once, multiple parts cassettes must be replaced, so it is necessary to move the parts cassettes many times. There is.

Problems to be Solved by the Invention However, with the above-mentioned conventional configuration, when replenishing parts, keys must be operated every time the parts are refilled, resulting in erroneous operations or errors caused by misreading the display on the operation panel. It is easy to do, and it takes a long time.

The problem was that the operating rate decreased.

In view of the above-mentioned problems, the present invention aims to improve the operating rate by making it possible to reliably replenish components in an electronic component automatic mounting machine in a short period of time.

Means for Solving the Problems In order to solve the above problems, the parts replenishment method of the present invention is as follows:
The process consists of a step of detecting that a part is missing, a step of storing a parts cassette with a missing part, a step of moving the parts cassette to a predetermined position, and a step of replacing the parts cassette.

For production The present invention has the following configuration according to the above-mentioned configuration.

That is, in the mounting process, parts cassettes that are determined to be out of parts are sequentially memorized during component detection, and when a key is given to manually move the parts cassette in the parts replenishment process, the predetermined parts cassettes can be replaced. A parts cassette is automatically moved to an easily fixed position and the parts cassette at that position is replaced. By repeating this process sequentially, parts can be replenished more quickly and reliably than in the past, reducing worker man-hours and increasing the operating rate of one machine.

EXAMPLE Hereinafter, a parts replenishment method according to an example of the present invention will be explained with reference to the drawings. FIG. 1 shows a flowchart of the operation in an embodiment of the present invention, and FIG. 2 shows a conceptual diagram of an electronic component mounting machine that performs this operation.

In FIG. 1, numeral 1 indicates a moving process, which is a process of moving the parts cassette 17. 2 is a take-out process, in which the mounting head 16 takes out parts from the parts cassette 17. 3 is a detection step, which is a step of detecting whether the parts cassette 17 is out of parts. 4 is the mounting process,
This is a process in which the mounting head 16 mounts components. 6 is a judgment step, which is a step of judging whether or not to replenish parts. Reference numeral 6 is a judgment step, which is a judgment step that concludes the mounting process. 7 is a storage process in which the control device 13 stores the parts cassette in which one part is missing. 8 is a change process and 1. This is the process of changing to the next spare parts cassette.

9 is about to enter, and as a key person from the rear control panel 16,
This is a step for instructing the process to proceed to the judgment step 10. 1
o is a judgment step, in which it is judged whether all out-of-parts cassettes have been replaced, and the process returns to the normal mounting process. Reference numeral 11 is a moving step, in which the out-of-part parts cassette is moved to a predetermined parts cassette replacement position. 12 is a sentence pattern process, which is a process of replacing out-of-part parts cassettes.

Regarding the parts replenishment method with the above configuration, the following is the first part.
The operation will be explained using FIG.

Here, the component mounting process shown in FIG. 1 (from moving process 1 to change process 8) is the component mounting process (moving process 3) shown in FIG.
4 to change step 41). In FIG. 1, the parts replenishment process is from the input process 9 to the replacement process 12.
I'm doing it at That is, when starting the parts replenishment work, the worker manually presses the key on the rear operation panel 15 in the input stage 9, and
Move the process to judgment step 1o. In the judgment step 10, it is judged whether the replenishment of all parts in the out-of-part parts cassette stored in the control device 13 has been completed, and if replenishment of parts is necessary, the process moves to the movement step 11. In the moving step 11, the parts cassette is automatically moved to a predetermined parts cassette exchange position. In the replacement step 12, the worker replaces the bar center and replenishes the parts, and the next input step 9 has the meaning of notifying the control device 13 that one part replenishment work has been completed. In this way, parts replenishment work is performed by repeating the input process 9 and the replacement process 12.

Here, the operator's actions are limited to key manual labor in the input step 9 and replacement of the parts cassette in the replacement step 12, and the work items for parts replenishment are greatly reduced. Furthermore, since the parts cassette replacement position is fixed at a predetermined position to make the work easier, one worker can easily identify the parts cassette to be replaced by marking adjacent parts of the parts cassette other than the moving part. It can be easily recognized and errors can be eliminated.

As described above, according to this embodiment, there are a step of detecting the missing parts, a step of storing the parts cassette with missing parts, a step of moving the parts cassette to a predetermined position, and a step of detecting the missing parts. By providing a process for replacing the parts, it is possible to prevent incorrect work when replenishing one part and shorten the work time.

The present invention also relates to a first conventional example (FIGS. 2 and 3).

(Fig. 4) is similarly effective.

Furthermore, in the embodiment of the present invention, the insertion process 9 is not dependent on the operator, and the completion of parts cassette replacement is recognized using a contact sensor, optical sensor, etc., and the replacement process 12 is also independent of the operator. By replacing parts cassettes using industrial robots, etc., parts replenishment work can be completely unmanned, and the operating rate of electronic component automatic mounting machines can be greatly improved.

Effects of the Invention As described above, according to the present invention, there are a step of detecting that a part is missing, a step of storing a parts cassette in which a part is missing, a step of moving the parts cassette to a predetermined position. By providing a process to replace parts cassettes, it prevents incorrect work during parts replenishment work and shortens the time required for each work.

And by reducing the number of man-hours, it is possible to improve the operating rate of the automatic electronic component mounting machine. Furthermore, completely unmanned operation reduces worker man-hours and allows electronic component automatic mounting machines to operate for long periods of time, significantly improving operating rates.
