Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to an aligning device for a powder molding press in which the aligning device is provided integrally with the press body and is rotatable.

[Prior Art] Conventionally, in a powder molding press, a press main body and an aligning device for taking out a molded product formed by the press main body and aligning them on a tray to be transferred are separately arranged as independent machines. The aligning device is usually installed on the front surface of the press body.

[Problems to be solved by the invention] However, in the powder molding press, various products are molded by the die set and the die set in the press body, and therefore the die set and the die must be replaced every time the molded product changes. .

The die set and die to be replaced must be made with extremely high accuracy and must be attached to the press body with high accuracy. Since this replacement work is done manually, a wide working space in front of the press body can be opened. It is necessary to secure sex.

However, in the case where the conventional press body and the aligning device are separately arranged, since the aligning device is usually installed on the front surface of the press body, the front surface of the press body is replaced every time the die set and the die are replaced. The aligning device must be moved in order to secure a working space, and there is a disadvantage that it takes time and manpower to remove and move the aligning device, and then reset and center it.

For this reason, conventionally, there has been a system in which wheels are provided in the aligning device to facilitate movement, and an adjusting mechanism for up, down, left and right, and front and rear is incorporated in the entire aligning device to speed up resetting.

There is also an aligning device that leaves the chute and the conveyor up to secure a working space in front of the press body. In any case, these aligning devices align the molded products on the tray after they are conveyed by the chute and the belt conveyor.

However, there are molded articles that should never be slid and molded articles that are unstable in shape, and these molded articles must be taken out and aligned immediately after molding.
A conventional chute and belt conveyor cannot be used.

The present invention has been made in consideration of the above circumstances, and an object thereof is to provide an aligning device that does not need to use a chute or a belt conveyor, and to secure and re-establish a work space when replacing a die set or a die. It is an object of the present invention to provide an aligning device for a powder molding press that can be easily set in a short time and can perform centering in the X, Y and Z directions of the press body and the aligning device with one touch.

[Means for Solving the Problems] In order to achieve the above object, an aligning device that takes out a molded product formed by a press body and arranges it on a tray that is transferred is made to be pivotable on the press body via a hinge mechanism. It is characterized in that the positioning pin, which is attached at a proper position on the aligning device side, is detachably attached to a positioning arm attached to the frame of the press body.

[Operation] With the above configuration, the aligning device is rotatably attached to the press body via the hinge mechanism, and the positioning pin on the aligning device side is detachable from the positioning arm on the press body side. When changing dies,
A work space can be secured by simply removing the positioning pin and rotating the aligning device, and in the case of re-setting, the work space can be re-set and centered by simply rotating the device and fixing it to the press body with the positioning pin.

Therefore, the aligning device can be attached to and detached from the press body with one touch, and the aligning device can be easily moved to the press body and positioned and fixed in a very short time.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In FIGS. 1 and 2, an aligning device 2 is pivotally attached to a press body 1 via a hinge mechanism 3.

The alignment device 2 includes a pickup device 7 having a pickup head 6 for taking out a molded product molded by the punch 4 and the die 5 on the press body 1 side, and the molded product sucked by the pickup head 6 on a tray 8. An X-direction pitch transfer device 9 for sequentially arranging the directional set pitches at regular intervals, and a set pitch in the Y-direction for arranging in a second row on the tray 8 after a predetermined number of molded products are lined up on the tray 8. The Y direction transfer table 10 that moves forward by a minute, the operation panel 11 that performs setting operations such as the feed interval and the arrangement method (staggered arrangement or lattice arrangement), and the surfaces of the punch 4 and the die 5 on the press body 1 side are regularly cleaned. And a brushing device 12 for cleaning.

When the parts are aligned on one tray 8, the next tray 8 is sequentially fed, and the tray 8 on which the parts are aligned is transferred to the Y-direction transfer table.
Along with the rail 10, it comes out to the tip side along the rail 13 and is transferred to the next process.

In addition, the residual powder and the like after cleaning with the brushing device 12 is collected and collected by suction air transportation.

The hinge mechanism 3 is composed of a press body side hinge seat 15, a hinge pin 16, and an aligning device side hinge seat 17. The positioning and fixing of the aligning device 2 to the press body 1 is performed by a brushing device on the aligning device 2 side. This is done by engaging a positioning pin 20 provided upright in the vicinity of 12 with a positioning arm 22 attached to a frame 21 of the press body 1.

As shown in FIG. 3, the positioning arm 22 is slidably disposed on a positioning fixing seat 23 attached to the frame 21 of the press body 1 via a guide pin 24. And
The positioning pin 20 on the side of the aligning device 2 engages with the engaging hole 22a of the positioning arm 22 so that the aligning device 2 is positioned and fixed to the press body 1. In FIG. 3, reference numeral 25 indicates a detent.

Since the powder molding press in this embodiment is as described above, the positioning arm 22 is removed from the positioning pin 20 with a finger,
The aligning device 2 is rotated about the hinge mechanism 3 so that the front surface of the press body 1 is opened with respect to the press body 1.

When the front surface of the press body 1 is opened, the die set can be easily replaced or the die 5 of the press body 1 can be inspected and adjusted when the parts to be powder-molded are changed. When these operations are completed, the aligning device 2 is pivoted in the opposite direction via the hinge mechanism 3 so that the positioning pin 20 is engaged with the engaging hole 22a of the positioning arm 22 and the aligning device 2 is attached to the press body 1. If it is positioned and fixed, it will return to its original state.

FIG. 4 shows an example in which the positioning pin 20 and the positioning arm 22 are engaged with each other by a manual lever system.
Is a lock arm, and 27 is a spring. Further, FIG. 5 shows an example of an engaging system of the positioning pin 20 and the positioning arm 22 as an automatic air cylinder system.
Reference numeral 28 indicates an air cylinder. These, FIG. 4 and FIG.
It goes without saying that the configuration shown in the figure can also achieve the same actions and effects as those of the example shown in FIG.

[Advantages of the Invention] As described above, according to the present invention, the aligning device is pivotally attached to the press body through the hinge mechanism, and the positioning pin on the aligning device side is positioned on the press body side. Since it is detachable, the working space can be secured simply by removing the positioning pin and rotating the aligning device when replacing the die set or die, and in the case of re-setting, rotate it in reverse to position it on the press body. It can be reset and centered simply by fixing it with a pin. Therefore,
The aligning device can be attached to and detached from the press body with one touch, and the aligning device can be easily moved and positioned and fixed to the press body in a short time, which is convenient.
