Abstract

PROBLEM TO BE SOLVED: To eliminate a trouble that a work is caught with a work table at the time of discharging the work by opening/closing the work table holding the work, adjusting a opening quantity and vertically dropping the work to discharge. SOLUTION: The work is loaded on work tables 6, 6, which are in contact with each other and integrated, and is machined by a laser beam machining head 1. A cavity to transmit the laser beam is formed in the work tables 6. When completing machining, a piston 4 is extended and arms 5, 5 operate in the opening direction. The work tables connected to an end part of the arms 5, 5 rotatable are opened horizontally as well as left/right along a guide rail 7 to form a path. The work is vertically dropped to be discharged. When completing discharge, the piston 4 is retracted to close the arm 5, the work tables 6, 6 are approached/integrated and receives a work to be machined next. A stroke of the piston 4 is adjusted in accordance with a size of the work.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work discharge device for a laser beam machine.

[0002]

2. Description of the Related Art A conventionally known work ejection apparatus such as a laser beam machine is disclosed in, for example, JP-A-62-292293. The technical content disclosed in this publication is such that a work is placed on a sword pin, a work support portion positioned directly below a processing head is rotated during processing, and control is performed so that the sword pin does not contact the work. Equipment.

The technical content disclosed in Japanese Utility Model Laid-Open Publication No. 60-181285 is that a slide tool (free bear) and a slip prevention tool (electromagnet) are combined on a working table, and each is rotatably disposed. A slip prevention device using an electromagnet is provided, and a slide device using a free bear is provided when the work is discharged.

[0004] In addition to the above-mentioned known examples, there is also known a hinge type work shooter device which performs inclined discharge.

[0005]

The conventional work discharge device of this type has a problem that the structure cannot be solved because the structure is complicated and expensive, and the work is caught on the work table.

The present invention has been made in view of the above points, and provides a work discharge device provided with an opening / closing mechanism for vertically dropping and discharging the work when the work is discharged after processing. With the goal.

[0007]

The present invention can solve the above-mentioned problems by providing the following constitution.

(1) A work discharging apparatus characterized in that a work table holding a work is provided with an opening and closing mechanism for opening and closing horizontally and horizontally, and the opening and closing amount can be freely adjusted, and the work can be dropped and discharged vertically.

(2) The opening / closing mechanism includes a piston / cylinder in a driving section, and each end of two arms is rotatably supported at the tip of the piston, and each other end of the arm is slidably opened / closed. The work discharge device according to the above (1), wherein the work discharge device is rotatably connected to each of the left and right work tables.

(3) The work discharge device according to the above (1), wherein the opening / closing amount can control the degree of opening of the arm and the work table by adjusting the amount of expansion / contraction of the piston / cylinder.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below.

FIG. 1 is a perspective view showing the structure of a work discharge device according to the present invention.

Referring to the drawings, 1 is a laser processing head, 2 is a laser center, 3 is a cylinder,
The ends of the arms 5, 5 are pivotally supported at the tip of the piston 4, and the other ends of the arms 5, 5 are connected so that the worktables 6, 6 can slide open and close along guide rails 7.

The operation will be described based on the above configuration.

A work is placed and processed in a region connecting the laser processing head 1 and the laser center 2 located immediately below the laser processing head 1 and on the upper surface of the work table where the work tables 6 and 6 are joined together. Is done. Note that a cylindrical cavity is formed on the surface where the work tables 6 and 6 are in contact with each other so that laser light can be transmitted (see FIG. 1).

When the machining is completed, the telescopic piston
The cylinder piston 4 starts to extend, and the arm 5,
5 moves in the opening direction, and slides horizontally and horizontally along the guide rail 7 from a state in which the work tables 6, 6 rotatably connected to the ends of the arms 5, 5 are in contact with each other and united. The work is dropped and discharged vertically through a passage formed by separating the work tables 6 and 6.

When the discharge of the work is completed, the piston 4 starts to move in the contracting direction, the arms 5 and 5 move in the closing direction, and the worktables 6, 6 slide and approach together along the guide rail 7 in conjunction with each other. It is ready to accept the workpiece to be processed next, and this process is repeated.

The stroke of the piston 4 can be adjusted according to the size of the work.
The degree of opening of the arms 5, 5 is also adjusted according to the operation of
Therefore, the worktables 6, 6 rotatably connected to the ends of the arms 5, 5, can be slidably opened and closed along the guide rails 7 to adjust the opening and closing amounts appropriately.

[0019]

According to the present invention, the opening / closing amount of the work table can be appropriately adjusted and controlled in accordance with the size of the work, and the opening / closing mechanism that opens and closes horizontally and left and right allows the work to drop vertically. Since the work can be reliably discharged and the work discharge process time is shortened, an improvement in work efficiency can be expected.
