Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a press loading device for loading a work into a press.

[Prior Art] Conventional press input devices include a robot (portable input device) and a dedicated input device.

[Problems to be solved by the device]

Although the robot has many functions and has an advantage that it can be flexibly accommodated, on the other hand, it is often not possible to follow a work mode such as a press having a short cycle time. Also, due to legal restrictions, all movable ranges are required to be inaccessible by people because of covers, shelves, etc., which leads to waste of space and rigidity of the entire system.
For example, if you can't use the robot and want to put it in by hand, the robot will get in the way.

Regarding the dedicated inserter, the conventional dedicated inserter is limited in the work to be processed, and its installation form often blocks the front surface of the press. Therefore, the characteristic that many kinds of things can be made by changing the die of the press main body is inevitable, and when the thing to be flowed changes due to model change etc., it causes waste such as removal of the input machine.

It is an object of the present invention to provide a press insertion device that can easily retract the insertion device outside the line when unnecessary and can follow the operation of the press machine with a short cycle time when used. To do.

[Means for solving the problem]

According to the present invention, the above object is achieved by the following press feeding device. That is, a lower transfer mechanism having a built-in work centering and positioning mechanism, a holding mechanism having a swing arm that can swing up and down, and a rodless cylinder that moves the holding mechanism in the work transfer direction while holding the work. And a lower feeding mechanism and an upper feeder mechanism are separated from each other, and each of the lower feeding mechanism and the upper feeder mechanism can be horizontally swiveled on a frame in front of the press body by a pin. Pressing device characterized by being connected.

[Action]

Since the upper feeder mechanism and the lower transfer mechanism that constitute the press loading device are supported by the frame so that they can be rotated half a turn, they can be easily saved outside the line by making a half turn to the save position when not needed. be able to.
Therefore, the charging device does not get in the way even when it is unnecessary.

The upper feeder mechanism swings the work holding mechanism to engage the work, and drives the work holding mechanism in the work feeding direction by the rodless cylinder to feed the work into the press machine. By adopting this swing type and rodless cylinder, the work holding and feeding mechanism can be remarkably simplified, and the upper feeder mechanism can be miniaturized, so that the above-mentioned swivel type support can be employed. Further, by simplifying the work holding and feeding mechanism, the in-lock and the like are simplified, and the press operation with a short cycle time can be sufficiently followed.

〔Example〕

Hereinafter, a preferred embodiment of the press dosing device of the present invention will be described with reference to the drawings.

As shown in FIG. 1 and FIG. 2, a press work input device 4 is provided in front of the press 2, and the work 6 is sequentially input into the press 2. The work 6 is sent by a roller conveyor (not shown) or the like, positioned at the position A in FIG. 1 by the stopper 8, and pressed by the press work input device 4 at the position B in FIG. 1 (center of the press 2). ) Are sequentially thrown in.

The work input device 4 for the press has an upper feeder mechanism 10
And a lower transport mechanism 12 provided therebelow. The lower transport mechanism 12 is a mechanism that can rotate the roller on which the work 6 is placed to transport the work 6 from the position C in FIG. 1 to the position A, and the upper feeder mechanism 10 hooks the work 6 to hook the work 6 in FIG. It is a mechanism for loading the work 6 from the position A to the position B. As shown in FIG. 1, the upper feeder mechanism 10 is connected by a pin 14 to a frame 16 on the front surface of the press main body so that the upper feeder mechanism 10 can be half-turned in the horizontal direction.
Also, as shown in FIG. 4, the lower transport mechanism 12 is also connected to the frame 16 on the front surface of the press main body by the same pin 14 so that it can be half-turned in the horizontal direction.

The upper feeder mechanism 10 includes a swivel frame 18 and a frame.
A rodless cylinder 20 supported by 18, a guide 22 extending along the frame 18, and a work holding mechanism 24 movable along the guide 22 and driven by the rodless cylinder 20. The rodless cylinder 20 is configured to take out the movement of a piston inserted in the cylinder to the outside of the cylinder by a belt penetrating the cylinder. The work holding mechanism 24 is connected to the belt to drive the work holding mechanism 24. Is done.

The work holding mechanism 24, as shown in FIG.
A work holding mechanism main body 26 that moves along, a swing type arm 30 that is vertically swingable and is connected to the work holding mechanism main body 26 by a pin 28, and the center of the work 6 attached to the tip of the swing type arm 30. It is composed of a work hooking portion 32 that can be inserted into a hole and an air cylinder 34 that swings the swing arm 30.

The work holding mechanism 24 and rodless cylinder 20 are
The position of the swivel frame 18 can be adjusted in the vertical direction by a screw jack 36 (second shown), and the vertical distance between the upper feeder mechanism 10 and the lower transport mechanism 12 can be maintained even if the size of the work changes. Is adjusted so that it can respond.

As shown in FIG. 4, the lower transport mechanism 12 includes a revolving frame 38 that half-rotates around the pin 14, a drive roller 40 supported by the revolving frame 38, a free roller 42, and a drive roller 40.
And a motor 46 for driving the motor through a chain 44.

 Next, the operation will be described.

When the work 6 is sent, it stops on the preceding work 6 at the position C in FIG. 1, is transferred to the press 2 side by the drive roller 40 of the lower transport mechanism 12, and the stopper 8 that interlocks with the position detecting photoelectric tube projects. Is positioned at position A.

The swing type arm 30 of the work holding mechanism 24 of the upper feeder mechanism 10 swings to the work side and the work catching portion 32
Enters the center hole of the work 6. Then, the rodless cylinder 20 is operated to load the work 6 from the position A in FIG. 1 to the center of the press 2 which is the position B. When the loading is completed, the swing-type arm 30 is lifted, the work catch 32 is disengaged from the work 6, and the rodless cylinder 20 returns the work holding mechanism 24 from the position B to the position A. After that, the above is repeated.

If there is a case where it is desired to manually insert the work, the upper feeder mechanism 10 and the lower transfer mechanism 12 are half-turned about the pin 14, and the press work input device 4 is removed from the pre-press position. , Retreat to the retreat position. Then, a person enters the pre-press position or sets another jig, and the work is manually put into the press. This removal does not hinder the press work input device 4, and the removal work is only half-turned, which is extremely easy.

Further, the upper feeder mechanism 10 is simplified and downsized by adopting the work holding by the swing type arm 30 and the transfer by the rodless cylinder 20, and by the downsizing, the half rotation and the turning as described above are performed. The structure can be adopted.

Further, by simplifying the upper feeder mechanism 10, various interlocks are naturally simplified, the operation can be performed quickly, and the press can be applied to a press having a short cycle time.

Further, since the upper feeder mechanism 10 and the lower transport mechanism 12 are separated and the distance between them can be adjusted by the screw jack 36, even if the shape and size of the work 6 flowing through the line is changed, It is possible to respond easily.

[Effect of device]

According to the present invention, since the upper feeder mechanism and the lower transfer mechanism can be horizontally half-turned, the upper feeder mechanism and the lower transfer mechanism can be moved from the press front position to the retracted position to facilitate the press front surface when unnecessary. It can be opened and the press mold can be changed easily, and the upper feeder mechanism and the lower transfer mechanism can be separated from each other, so even when the type of work changes and you want to change the interval between the upper feeder mechanism and the lower transfer mechanism. This can be easily dealt with, and since the upper feeder mechanism is composed of the swing arm type work holding mechanism and the rodless cylinder, there is an effect that the apparatus can be simplified and the operation speed can be increased.
