Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION A blanking press is used for a press line including a blanking press for simultaneously transferring two blanks taken in two rows from a strip material by a blanking press and pressing two blanks simultaneously. This is a technique related to a blank material aligning apparatus for a press machine that changes the position and the attitude of the blank material with respect to the transport of the material.

[0002]

2. Description of the Related Art The prior art relating to a blank material aligning device for changing the attitude of a blank material which is simultaneously taken out of a strip material by a blanking press in a row and two rows includes:
50-150219 and 50-149729.
There is.

[0003] However, these prior arts are blank material aligning apparatuses for transferring blank materials taken in two rows from a strip material at the same time and changing the position and posture of the blank materials with respect to each other. There is a problem that it cannot be used as a blank material aligning device for a press machine that transports two blank materials and changes the mutual position and orientation of the blank materials.

[0004]

A blank material which is used in a press line including a blanking press and is taken out of a strip-shaped material by a blanking press in two rows and two pieces at a time is carried out, and the positions and postures of the blank materials are determined. The present invention provides a blank material aligning apparatus for a press machine, which is changed and carried into a press of the next process, and simultaneously presses two blank materials.

[0005]

An aligning device is provided between a blanking press and a press in the next step of a press line including a blanking press and at least one press for performing a press process in the next step, The transport of the blank material is performed by a transport device.

[0006] The transfer device uses, for example, a press robot that transfers a conventionally used pressed part.
It has a transport bar that holds two sets of chuck means for chucking two blanks at the same time, chucks blanks taken in two rows and two rows by a blanking press, and simultaneously positions the blanks on a receiving table of an alignment device. Then, the two blanks whose postures have been changed are chucked, and the transport bar is moved, and the blanks are transported two by two to the alignment device and the press in the next process.

[0007] An aligning device comprising two sets of aligning means, wherein the aligning means is provided on a rotating shaft which is rotationally driven by an actuator and whose position can be adjusted on a plane, and a non-rotatable blank receiving table is provided in accordance with a blank material. The position of the rotating shaft is adjusted in advance in accordance with the part to be pressed, and blanks taken in two rows and two at the same time by a blanking press are received on a receiving table, and the rotating shafts are moved 90 degrees each.
After rotating the cradle by one degree and moving the cradle to a position in one row to change the position and orientation of the blanks, the blanks can be supplied to the next press.

[0008] By the transport device, the blank material taken in two rows and two blanks simultaneously by the blanking press and the blank material on the receiving table are simultaneously transported to the next press, that is, transported to the next press. When the blank material on the pedestal of the aligning device is removed by the transport device, the rotating shaft of the aligning means is rotated 90 degrees to return the cradle to the original position, and the blank material transported from the blanking press is received, As soon as it is received, the rotating shaft is rotated and the cradle is rotated 90 degrees to prepare for the next conveyance.

In this way, the position and orientation of the blanks taken in two rows and two pieces are changed by the aligning means, transferred to the conveying device, and the blanks taken in two rows and two pieces by the blanking press are removed. Conveyed sequentially to the next process press, 2
The blank material taken in two rows is automatically pressed.

[0010]

While the blank material taken in two rows by the blanking press is conveyed to the next step press, it is moved to one row position and its posture is changed by 90 degrees. As a result, two blanks can be automatically pressed at the same time.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. In FIG. 1, a blanking press 1 is formed from a belt-shaped material 15 fed by a material feeding device 14.
The blank materials A1 and B1 taken in two rows before and after
Chuck means 4A fixedly mounted on the transfer bar 4 of the transfer device 2
Are taken out of the blanking press 1 at the same time, and are conveyed onto the receiving tables 9A and 9B of the alignment device 5.

The blank materials A2 and B2 transported from the blanking press 1 and placed on the receiving tables 9A and 9B are:
The rotating shafts 8A and 8B rotate 90 degrees to the right, respectively, to move the position, and the blanks A3 and B3 each move 90 degrees.
It is turning right by degrees.

[0013] The blanks A3 and B3
At the same time, the blanks A1 and B1 in the blanking press 1 are chucked by the chucking means 4A fixed to the transport bar 4 and the chucking means 4B is chucked. And the blank moves to A2, B2 and A4, B4.

The transfer bar 4 is held by the main body 3 of the transfer device 2 so as to be movable up, down, left and right, and chuck means 4A, 4B are fixedly provided at both left and right ends. The chuck means 4A, 4B
In the present embodiment, a vacuum cup is used, but it goes without saying that an electromagnetic magnet or a clamper for opening and closing a nail may be used.

Next, the blank material A2,
Changing the position and orientation of B2 to A3 and B3 will be described using the blank material A2. The reference point a2 of the blank material A2 conveyed from the blanking press 1 is located at a position (X1, Y1) from the center O of the alignment device 5, and the reference point a3 (X
(2, Y2), the rotating shaft 8A is rotated, thereby rotating the cradle 9A.

Since the reference point a2 and the reference point a3 are determined by the parts to be pressed, the reference points a2 and a3 are used to move the center (X,
The position of Y) is determined. That is, since it is obtained by the equations (1) and (2) in FIG. 2, when the part to be pressed is determined, it is adjusted to this position in advance. The same applies to the case where the blank material B2 is moved to B3.

When the rotating shafts 8A and 8B rotate rightward by 90 degrees and move to the blanks A3 and B3, the moved blanks A3 and B3 rotate rightward by 90 degrees with respect to the blanks A2 and B2, respectively. doing.

The pedestals 9A, 9B are provided on the rotating shafts 8A, 8B.
Holding portions 8A1 and 8B1 for holding the
Are provided, and the receiving tables 9A and 9B for holding the blank materials A2 and B2 corresponding to the parts to be pressed are easily replaceable.

Next, a mechanism for adjusting the positions of the rotating shafts 8A and 8B will be described with reference to the rotating shaft 8A. 1st mobile stand 10A, 1
OB is provided on the main body 6 of the aligning device 5 so as to be movable left and right (X direction), and the second mobile tables 11A and 11B are provided on the first mobile tables 10A and 10B so as to be movable back and forth (Y direction). These are fixed after changing the position.

The rotating shafts 8A and 8B are
A and 7B are driven to rotate, and these are
A, 11B, so that the rotating shaft 8A,
8B can be adjusted. In the present embodiment, the rotating shaft 8A,
Although the actuators 7A and 7B are used to rotationally drive the 8B, it goes without saying that a device that rotationally drives with a cylinder, a motor, or the like may be used.

As is apparent from the above description, the aligning means of the aligning device 5 of the present embodiment includes the actuators 7A and 7B.
, Rotating shafts 8A and 8B, receiving stands 9A and 9B, first moving stands 10A and 10B, and second moving stands 11A and 11B.

[0022]

The strip material (coil material) is taken in two rows and two pieces by a blanking press.
The blanks are transferred individually, and the position and orientation of the blank are changed by the aligning device provided between the blanking press and the next process press. This press line automatically presses two parts at the same time. It can be a press line for processing.
