Abstract

PURPOSE:To provide an electronic component supplying apparatus which clearly separates the display for the cases where the same type of components are perfectly used in all stations or in a part of the stations. CONSTITUTION:In an electronic component supply apparatus comprising a plurality groups of stations respectively loading a plurality types of components wherein each group is formed by at least one station loading a kind of component and also LEDs for displaying existence or no-existence of components as a result of detection in each station, no-existence condition of components in the stations 11 to 15 is displayed by slower flickering of LEDs and no- existence of components in a group of stations 11 to 13 or in all stations 14, 15 is displayed by quick flickering of LEDs.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supply device installed in an electronic component mounting machine, and more particularly to a display format for indicating that a component loaded at a station provided in the component supply device is out of stock.

0002

2. Description of the Related Art An electronic component mounting machine is provided with a plurality of stations on which components are placed. Each of these stations is equipped with a lamp that indicates when a part is out of stock. Previously, the lamp at a station that was out of parts would blink, and the lamp at a station where parts remained would be lit. .

0003

[Problem to be Solved by the Invention] However, the same type of parts are often placed on multiple stations among the above stations, and in this case, even if one station runs out of parts, the other stations may run out of parts. There are still similar parts in the station and the equipment will not stop. At this time, even if all the stations run out of parts of the same type and the equipment stops, the conventional display method only shows the lamp of the station where the parts are out of stock flashing, indicating which type of parts are missing and the equipment has stopped. I didn't understand.

[0004] The present invention was developed in view of the above situation, and it is an object of the present invention to clearly distinguish and display cases where parts of the same type are missing at all stations and cases where parts are missing at some stations. The purpose of the present invention is to provide a parts supply device that can perform the following functions.

[0005]

[Means for Solving the Problems] The parts supply device of the present invention includes a group of at least one station each loaded with one type of parts, and a plurality of stations each loaded with a plurality of types of parts. In the parts supplying apparatus, the parts supplying apparatus is provided with a display means for detecting and displaying the presence or absence of parts at each station. The present invention is characterized by providing a second display form for displaying out-of-parts.

[0006]

[Operation] In the parts supply device configured as described above, the first display form displays out-of-parts at each station that loads parts, and displays all out-of-parts at at least one station where the same type of parts is loaded. Since the second display format is different from the second display format, it is possible to easily know the out-of-part type that caused the device to stop.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the parts supplying apparatus of the present invention will be described below with reference to the drawings.

FIG. 1 shows the configuration of this embodiment. A tray 1 provided at one station is provided with a detection means (not shown) for detecting the presence or absence of a component placed on the tray 1, and a signal output from the detection means is input to the CPU 2. A memory 3 is connected to the CPU 2 in which a station number and a part number to be placed on the tray 1 of the station are stored. Furthermore, a signal from the tray 1 drives an LED 4, which is a display means corresponding to the tray 1, via a drive circuit 5. Also connected to the CPU 2 are a tray unit 8 that transports the tray 1 to each station via drive units 6 and 7, and a head unit 9 that extracts and transports parts from the tray 1.

Next, the operation of this embodiment will be explained with reference to the flowchart shown in FIG. 2 and the display example of the LED 4 shown in FIG. FIG. 2 shows the driving operation of one LED 4. In step 101, the component supply apparatus is started, and in step 102, the detection means of the tray 1 of each station and the LED 4 corresponding to each station are electrically connected via the CPU 2 and the drive circuit 5. Next, in step 103, the presence or absence of components on the tray 1 is detected by the detection means. Step 1 if there are parts on tray 1
At 04, the corresponding LED 4 lights up. For example, Figure 2
As shown in (a), all parts are placed on each tray 1 of three stations 11, 12, 13 where part A is placed and two stations 14, 15 where part B is placed. If so, all corresponding LEDs 4 will light up. Then, in step 105, the head section 9 is driven via the drive section 7 to extract and transport parts from the tray 1.

In step 103, for example, as shown in FIG.
), if it is detected that tray 1 of station 14 is out of parts, and in step 106 it is detected that tray 1 of station 15 has part B, then in step 107 the part corresponding to station 4 is Only LED 4 blinks slowly. Step 106
In step 108, if it is detected that tray 1 of stations 14 and 15 is out of parts, as shown in FIG.
Both LEDs 4 corresponding to 15 blink at a fast speed. Then, in step 109, the operation of the device is stopped.

Here, in step 110, the drive section 6
If the tray unit 8 is driven through the L to replenish the station 15 with parts, for example, the process returns to step 107 and the L corresponding to the station 15 is refilled as shown in FIG. 2(d).
ED4 lights up and LED4 corresponding to station 14
flashes slowly. If parts are not replenished in step 110, the device remains stopped in step 111. The same applies when part A runs out.

According to this embodiment, even if one station runs out of parts, if there are parts of the same type in other stations and the device does not stop, only the LED corresponding to the station where the parts are out flashes slowly, When all the parts of a type are exhausted, all the LEDs corresponding to the stations that are out of parts flash at a high speed. Therefore, the operator can easily determine which product type is out of all its parts, and can promptly replenish parts.

In the above embodiment, the state of out-of-parts is determined by L.
Although the case where this is done by changing the blinking speed of the ED4 has been described, the display form is not limited to this, and for example, the color of the lamp may be changed.

[0014]

[Effects of the Invention] As explained above, according to the parts supply device of the present invention, the display is displayed when all the same types of parts placed on a plurality of stations are gone, and when they are in at least some stations. Since the shapes are different, the operator can easily identify the product type for which all parts are missing, and can quickly replenish parts.
