Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a component supply device that supplies electrical components to a predetermined component insertion/mounting path of an automatic electrical component mounting machine.

BACKGROUND OF THE INVENTION In recent years, component supply devices for automatic electrical component mounting machines have taken various forms. One of these methods is a method in which the component supply table itself moves to supply components to a predetermined insertion/mounting path (hereinafter referred to as a random access method).

An example of a conventional random access type component supply device will be described below with reference to the drawings.

FIG. 3 shows an example of a conventional parts supply device.

The parts supply stand 1 stores electrical parts.

The rotation of the drive source 2 drives the feed screw 4 through the transmission belt 3.
By rotating it, it moves arbitrarily on the track 5 and stops arbitrarily at a position where it can supply the specified electrical component to a predetermined insertion/device path 6.

The electrical components are sequentially supplied while repeating the above operations.

Problems to be Solved by the Invention However, in the above-mentioned component supply device, the component supply table 1 is constantly moving during supply operation, and the supply operation must be stopped when replenishing or replacing electrical components. I couldn't do it until after. In particular, the amount of time it takes to replace electrical parts has become a major factor in the decline in machine operating rates, as the recent trend toward high-mix, low-volume production has become very strong.

The present invention solves these problems.

The purpose of this is to eliminate the downtime of the supply operation for electrical component replacement work of the random access component supply device, and to improve the machine operating rate.

Means for Solving the Problem In order to solve this problem, the present invention arranges a plurality of parts supply stands each having a drive shaft on a common track, and connects one drive source to the plurality of parts through a clutch device. It is designed to be connected to the drive shaft of the parts supply stand.

Effect: With this configuration, if one component supply table is in operation while the other component supply table is stopped, parts can be replaced in advance on that component supply table. This allows for immediate supply of the next component once the component supply table in operation has finished supplying the parts, contributing to improved machine operating rates.

Example Below, one drawing (Fig. 1, 2
The explanation will be based on Figure).

In the figure, IO and 11 are two component supply tables supported on a common track 12, respectively. The parts supply stand 1
0.11 are each equipped with a lead screw 13.14.

One end of each feed screw 13, 14 is connected to a transmission belt 15.
The drive source 18 is connected to the drive source 18 via a clutch device 17 that is common to the clutch device 16 . 19 indicates a predetermined insertion/attachment path.

The operation of the component supply device configured as above will be explained based on FIG. 2.

First, if the parts supply stand 11 side performs supply operation,
The clutch on the transmission belt 16 side of the clutch device 17 is connected to transmit the rotation of the drive source 18 to the feed screw 14. The component supply table 11 sequentially supplies electrical components to the insertion/mounting path 19 while repeatedly moving left and right. At this time, the one-component supply table 10 is stopped at one end of the track 12, and the clutch on the transmission belt 15 side of the clutch device 17 is disengaged. In order to prepare for the next production, the worker replaces the electrical components in the parts supply table 10 during this time, and when the parts supply on the part supply table 11 side is finished, the worker replaces the parts supply table 11. Move it to the other end of the track 12,
The clutch on the side of the transmission belt 6 is disengaged, and then the clutch on the side of the transmission belt 15 is connected, and supply operation on the parts supply stand 10 side is started. At the same time, the component replacement work on the component supply stand 11 side is also started.

In this example, the aim was to replace parts without stopping the supply operation in high-mix low-volume production, but it is also possible to perform parts replenishment without stopping the supply operation in so-called low-volume high-volume production in which a large number of the same type of parts is supplied. It is also possible to do so.

Effects of the Invention As described above, according to the present invention, a plurality of component supply stands each having a drive shaft are arranged on a common track, and one drive source is connected to the drive shaft via a clutch device. Even with a random access type parts supply device, parts can be replaced or replenished without stopping the supply operation, improving machine operation efficiency.
