DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tray supply device, and more particularly to a tray supply device for supplying and collecting a tray containing components to an automatic assembly line.

[0002]

2. Description of the Related Art An automation line is a facility for producing a product by supplying a large number of parts and automatically assembling them. This automation line generally includes a component supply device that automatically supplies components.

[0003] The above-mentioned components vary in size and weight from a small volume such as a screw to a large volume and weight such as a chassis. Small parts, such as screws, are supplied to the automation line by a parts feeder, such as a parts feeder.

Also, parts having a relatively large volume and weight, such as a motor for a washing machine and a clutch assembly for a washing machine,
Parts cannot be supplied to the assembling apparatus using the parts feeder as described above. Further, components that cannot be erected on the bottom surface are supplied to the component supply device while being stored in a tray.

FIG. 1 shows a tray supply device. In FIG. 1, the tray supply device 10 includes a tray conveyor 12, a Shisa lifter 14 placed at a standby position, and a tray discharge unit 16. The tray 13 is stacked in the cart 11, and the cart 11 is moved to the tray conveyor 12. At this time, the tray 13 in the cart 11 is manually moved to the tray conveyor 1.
Moved to 2.

[0006] The tray conveyor 12 is a stack of trays 1
3 to the standby position, ie, scissors l
ifter) 14. At this time, components inside the tray 13 are drawn out by a component supply device (not shown) and supplied to the automation line. When all the components in the tray 13 are supplied, the tray discharge unit 16 such as a pick-and-place device can transfer the empty tray 13 to the automation line 2.
Discharge to the outside of 0 and drop. At this time, the Shisa lifter 14 raises another tray 13 in which the components 15 are stored to the component supply position.

[0007] However, the tray in which the components are stored is too heavy to be supplied to the component extracting device by a person. That is, the supply speed of the tray is reduced, and the productivity of the product is reduced.

On the other hand, the tray discharge unit 16 discharges the empty tray to the outside of the component supply device by dropping the empty tray. However, the empty tray is liable to be damaged by being arbitrarily dropped by the discharging device, and must be cleared by a person to reuse it.

[0009]

SUMMARY OF THE INVENTION The present invention has been devised in order to solve the above-mentioned problems, and an object of the present invention is to easily supply a tray in which components are stored, and to use an empty tray from which components are drawn out. To provide a tray supply device for discharging and aligning the sheets.

[0010]

In order to achieve the above-mentioned object, a tray supply device according to the present invention includes a tray supply unit for supplying a tray in which components are stored, and a tray collection unit for collecting an empty tray. .

[0011] The tray supply unit includes a first bogie storage unit, a tray transfer, and a tray lifter. The first truck storage unit stores a truck on which the trays are stacked. When the cart is stored in the first cart storage section, the tray lifter raises the tray transfer to the height of the tray conveyor via the open section of the cart. At this time, the tray transfer moves the tray to a tray conveyor. The components in the tray are drawn out to the automation line by the component supply device, and the empty tray from which the components have been drawn out is discharged to the tray collection position by the tray discharge unit.

The discharged empty tray is collected by a tray collecting section. The tray collection unit is the second bogie storage unit,
A tray collection table, and a second Shisa lifter are provided. The second trolley storage section stores the empty trolley and holds the trolley using the second holder. At this time, the second Shisars lifter raises the tray collection table, and the tray discharger picks up an empty tray at the component supply position and places it on the tray collection table.

According to the present invention, the parts are supplied to the automation line at a high speed because the tray is supplied easily and quickly to the automation line. In addition, empty trays are automatically collected and aligned to prevent damage to the trays, thereby reducing manpower, improving product productivity, and contributing to cost reduction.
