Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a kit feeding device for components in an assembly line for electrical products and the like.

Conventional configuration and its problems Conventionally, the method of supplying kits of parts on an assembly line has been to install something similar to a nut feeder or a parts box near each assembly device and directly supply parts. Ta.

Particularly in recent years, robot equipment has been introduced and automated, but as shown in Figure 1, the range of movement of the robot equipment is narrow and the size of the parts box is large.
Only one or two types could be supplied to each robot device.

That is, in FIG. 1, 101 and 102 are robot devices, 103 and 104 are component gripping devices, 105 is a conveyor device, 106 is a jig barret on which products and kit parts are placed, 107, 108, and 109 are products A, B, This is the parts box where C is stored.

The operation will be explained below.

The jig 106 conveyed by the conveyor device 105 first stops at the M station.

The robot device 101 first takes out part A from the parts box 107 using the gripping device 103 and places it on a predetermined position on the jig 106. Next, part B is taken out from the parts box 108 and placed in the same manner. When the setting of parts A and B is completed, the jig bullet 106 is again conveyed by the conveyor device 105 and stopped at the N station. At the N station, the C component is similarly set by the robot device 102.

In this way, in the conventional method, when separating a large number of parts onto the jig pallet 106, a large number of robot devices and a large space for supplying parts are required, which reduces investment efficiency. There was a problem with the surface.

Purpose of the Invention In view of the above-mentioned drawbacks, the present invention concentrates the parts supply section in one place, collects the parts boxes, and efficiently supplies many types of parts with one robot device, thereby reducing management and investment. This provides a parts supply device that is extremely advantageous in terms of effectiveness.

Structure of the Invention The present invention includes a supply unit that has a function of separating one box at a time from the bottom of each of a plurality of component boxes stacked in a single row or double rows, and a supply unit that drops the separated component boxes directly below. ,
It consists of a transport device for transporting to a designated location, a function for collecting parts boxes transported at the designated location, and a robot device that can run on its own in parallel to the component supply section, By arranging many types of component supply sections in parallel at one location and using a robot device that runs parallel to the robot device, components can be efficiently supplied in kits, which is extremely advantageous in terms of component management, assembly, and investment.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 2 to 5, 1 is a robot device, 2 is a gripping device, 3 is a moving body that runs parallel to the parts box A-E, 4 is a motor with a reducer that drives the moving body 3, 5 is a pinion gear connected to the motor shaft, 6 is a rack gear that meshes with it, 7 is a running wheel, 9 is the main body of the parts supply device, 1o is a conveyor device that conveys the jig bullet 11, and 12 is a plurality of stacked parts boxes. A drawer metal fitting for separating boxes one by one from the bottom; 13 is a cylinder for the drawer; 14 is a receiving plate that supports the separated parts boxes; 15 is a receiving plate for receiving empty parts boxes; 16 is a cylinder that opens and closes the receiving plate 14 to drop the empty parts box; 17 is a pull-in fitting that pulls the empty parts box from the conveyor device 15 to the collection position; 18 is its drive. 19 is a push platform for stacking empty parts boxes from the bottom at collection position #V or U, 2o is a lift cylinder that provides the drive, 21 is a cylinder with a fulcrum 23 at the base and a slope on one side of the tip. The hooks 22 are springs that draw the two hooks 21 inwardly.

The operation of the component supply device configured as described above will be described below.

The parts boxes containing the kit parts A, B, C, D, and E to be assembled are stacked in the supply section of each row, and are moved to the Q position by the drawer fitting 12 at the bottom P position of each row. It is separated and placed on the receiving plate 14. In this state, the robot device 1 suspended from the upper part of the parts supply device 9 via the wheels 7 is placed on the jig pallet 11 conveyed to the L position by the conveyor device 1o, based on the taught contents. Parts A, B, C, D, and E are sequentially supplied to corresponding positions while self-propelled.

An empty parts box is detected by the take-out count of the robot device 1, and when the receiving plate 14 is opened left and right by the cylinder 16, it falls onto the conveyor device 15, and is placed in the designated place according to the type of the parts box. It is transferred to the S position or the T position. From the S position or T position, the cylinder 18 moves to the collection position U or V via the retracting fitting 17.
It is pulled in directly below the position and lifted by the lift cylinder 20 via the pusher 2o. During this lifting, both ends of the upper part of the empty parts box hit the slopes of the hooks 21, and the hooks 21 are pushed out while spreading the springs 22. When the empty parts box passes the slope and the bottom surface of the empty parts box reaches a position slightly beyond the flat part of the hook 21, the lift cylinder 2o descends, and the empty parts box also descends slightly.
The bottom surfaces of the empty parts boxes rest on the flat part of the hook 21, and stacking is performed.

As described above, according to this embodiment, there is a component supply unit that has a function of sequentially separating various full component boxes stacked in double rows one by one at the lowest position, and an empty component box. Depending on the type, supply of parts boxes and collection of empty parts boxes can be done in one step by installing a collection device that stacks and collects empty parts boxes sequentially from the bottom to the designated collection position at a designated collection position.
It can be done compactly and intensively in just one place.

Furthermore, by providing the main body of the parts supplying apparatus with a robot device that can run on its own in parallel to the parts supply section, there is an effect that a single robot device can supply many types of parts.

In this embodiment, the empty parts box at the Q position was dropped by opening and closing the receiving plate 14, but in consideration of shock and damage when dropped, an elevating device was further provided on the receiving plate 14. It may be opened and closed after being lowered.

In addition, the empty parts box collection device was designed to collect the empty parts boxes by stacking them one by one from the bottom, but the push stand 19 was sequentially pushed down by a motor corresponding to the height of the parts boxes via a ball screw. , they may be collected by stacking them from the top.

Effects of the Invention As described above, the present invention has a parts supply unit that separates the bottom rows of various parts boxes stacked in double rows, and a conveyance device that utilizes the space below the parts supply unit to remove empty parts boxes. By collecting the parts in a sequential manner in a predetermined collecting apparatus placed in parallel with the parts supplying section, an extremely compact parts supplying apparatus can be realized.

In addition, by equipping the parts supply section with a robot/nod device that can run on its own in parallel, it is possible to supply many types of parts with one robot device, which is extremely effective in terms of management and investment effectiveness. It is advantageous and the effect is great.
