Abstract

PURPOSE:To adsorb and hold a work in response to the normal operating cycle time of a press machine by pressing one side to the corresponding face side of the protruded section of a lower mold before the other side of the work such as a trunk frame is adsorbed and held. CONSTITUTION:The tip edge section of one side 1a of a work is lifted horizontally by a lifter 8 after it is press-molded. A work handling device 7' is then moved by a crank device and located between both molds 4 and 6. When the roller 14 of the handling device 7' nears a slant section at one end of a rail 17, the upper end of the other side 1b of the work 1 is pressed to the face 5a side corresponding to the protruded section of the lower mold 6 by a pressing body 14. The work handling device 7' is then guided and lowered by the inclination at one end of the rail 17. An adsorbing cup 9a is brought into contact with one side 1a of the work 1 to adsorb and hold the work 1.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a workpiece handling device for taking out a workpiece press-molded by an upper mold and a lower mold from the lower mold.

(Prior Art) In general, a trunk frame (work) l for reinforcing the trunk lid of an automobile shown in FIG. ing. Such a trunk frame 1 is formed by press molding using an upper mold 4 having a concave part 3 and a lower mold 6 having a convex part 5, as shown in FIG. will be applied. When both molds 4 and 6 are opened after press molding, the trunk frame l is placed on the convex portion 5 of the lower mold 6 with one side 1a thereof inclined. Then, as shown in FIG. 6, this trunk frame is taken out from above the convex part 5 of the lower mold 6 by the work handling device 7 and transported to the next process. That is, the work handling device 7 is equipped with a lifter 8 and a suction means 9.
After the tip edge of one side 1a of the trunk frame 1 on the convex portion 5 of the trunk frame 1 is raised by the lifter 8 to a horizontal state, a plurality of suction cups of the suction means 9 are placed on the upper surface of this one side 1a. The trunk frame 1 is taken out from above the convex portion 5 by bringing the 9a into close contact with each other and suctioning and holding the trunk frame 9a by vacuuming.

(Problem to be solved by the invention) In such a conventional work handling device 7,
When the tip end edge of one side 1a of the trunk frame l is raised by the lifter 8 and made horizontal, the entire trunk frame l changes from the state shown by the solid line in FIG. 5 yua (after 4iJ). As a result, the position of the trunk frame l relative to the suction cup 9a is misaligned, and the suction cup 9a comes into contact with the hole 2 or the uneven surface of one side 1a of the trunk frame l, thereby suctioning and holding the trunk frame l. As a result, the press machine becomes inoperable and productivity decreases. It is also conceivable to slow down the lifting speed of the lifter 8 to prevent the trunk frame l from shifting, but this would slow down the work handling cycle time and would not be compatible with the operating cycle time of a normal press machine.

The present invention has been made in view of the above circumstances. 1. It provides a work handling device that can cope with the operating cycle time of a normal press machine and can easily and reliably suction and hold a work such as a trunk frame. The purpose is to

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a state in which press molding is performed by an upper mold and a lower mold, and one side is inclined on the convex part of the lower mold. After the one side of the workpiece having a side abbreviated shape that has been subjected to IaW is raised by a lifter and made horizontal, the one side is sucked and held by a suction means, and the workpiece is moved to the convex part of the lower mold. In the workpiece handling device that takes out the workpiece from above, a pressing means is provided for pressing the other side of the workpiece against the corresponding surface of the convex part of the lower mold before the one side side is sucked and held by the suction means. It is characterized by:

(Function) When one side of the workpiece is raised and leveled, the other side of the workpiece is pressed against the corresponding surface of the convex portion of the lower mold by the pressing means, so that the workpiece does not shift.

(Example) An example of the present invention will be described below with reference to FIGS. 1 to 5. In addition, in this invention, the same code|symbol is attached|subjected to the drawing about the same part as the above-mentioned conventional art, and it is demonstrated. As shown in FIGS. 3 and 4, the workpiece handling device 7' of the present invention includes a pressing means IO for pressing the other side 1b of the workpiece l against the corresponding surface 5a of the convex portion 5 of the lower mold 5. The only difference from the conventional method is the provision of this feature. The pressing means 10 is provided with curved support rods 12 at both ends of one suction cup support frame 11, and brackets 13 are provided on these support rods 12 so as to be movable and adjustable in the directions of arrows A and B. A pressing body 14 made of the following is attached.

The drive structure of the work handling device 7' is as follows. The work handling drive unit 15 is a press equipment a.
It is fixed on the upper side of 16. The upper part of the work handling device 7' is attached to a rail 17 provided at the lower part of the work handling drive unit 15 so as to be movable back and forth by a roller I9 provided on a bracket 18.

One end of the rail 19 (the end on the side of the press device 16) is inclined downward.

The work handling device W17' is rotated in the front and back direction (
It is designed to reciprocate in the horizontal direction (in the figure). In addition, in FIG. 3, 20 is a ram of the press device 16, 21 is a bolster thereof, and 22 is a conveyor.

And the roller 19 of the normal work handling device 7'
is located on the other end side of the rail 17 (point 20 in FIG. 3). In this state, the trunk frame l shown in FIG. The tip edge of side 1a is raised by lifter 8 to form a horizontal shape. Thereafter, as shown in FIG. 4, the workpiece handling device 7' is moved to the left in the figure by a crank mechanism and positioned between the two molds 4.6.

When the roller 14 of the workpiece handling device 7' reaches the inclined part at one end of the rail 17, the workpiece handling device 7' releases the pressing body 14.14.
As a result, the upper end of the other side tb of the trunk frame l is pressed against the corresponding surface 5a of the convex portion 5 of the lower mold 6. Thereafter, the work handling device 7' is guided by the slope of one end of the rail 17 and descends, and the workpiece handling device 7' is lowered to the trunk frame 1.
A suction cup 9a is brought into contact with one side la of the trunk frame 1, and the trunk frame 1 is suctioned and held in the state shown in FIG.

Thereafter, the trunk frame I is taken out from the convex portion 5'' of the lower mold 6 by moving the work handling device 7' between the two molds 4 and 6 in the direction of the arrow in FIG. It can be moved to the next process.

(Effects of the Invention) As described in ``2'' below, the present invention is characterized in that the product is press-molded by a mold 1 and a lower mold, and is placed on the convex part of the lower mold with one side inclined. Surface measurement ■ After raising the one side of the 7-shaped workpiece using a lifter and making it horizontal, the one side was suctioned and held by the suction means, and 11;
j In a workpiece handling device that takes out the workpiece from above the convex part of the subordinate mold, before the one side side is sucked and held by the suction means, the other side of the workpiece is placed 11 on the corresponding surface of the convex part of the subordinate mold. This device is characterized by being provided with a pressing means for pressing on the side.

Therefore, it is possible to cope with the operating cycle time of a normal press machine, and to easily and reliably suction and hold a workpiece such as a trunk frame.
