Further, the gripping arms 14, 14 are shown in FIG.

As shown in FIGS. 4 and 5, the centering arm 13
A substantially intermediate portion thereof is rotatably supported by a fixed shaft 27° 27 provided on the lower member 8b of the roder main body 81 and perpendicular to the rotating shaft 16 supporting the rodder body 81.

As shown in FIG. 4, each of the gripping arms 14, 14 is attached to the fixed shaft 27, 27 so that two of them are located on one side of the workpiece A to be gripped, and the tip thereof is
The pairs are connected by a connecting rod 28 so that they can rotate at the same time, and clamp pads 29 are provided protrudingly from the distal ends at positions facing each other.

Further, shaft rods 30, 30 are provided between the proximal ends (distal ends in the illustration) of the gripping arm 14.14, and one end of a link 31.31 is pivotally connected to the shaft rods 30, 30. , the other ends of these links 31 and 31 are fixed to the tip of the piston rod 33a of the clamp cylinder 33 by a pin 32, and a joint bracket 34? & is pivotally connected, and the clamp cylinder 33 is connected to the centering cylinder 1.
9 and installed on the loader main body 81.

The loader main body 81 is divided into an upper member 8a provided with wheels (not shown) and a lower member 8b provided with the centering arm 13 and clamp arm 14. The lower member 8b is connected to each other by a book guide pawl 35, and is configured to be moved up and down by a lift cylinder 36 installed on the upper member 8a side.

Thus, by the first loader device 1, for example, a workpiece A to be subjected to peeling processing is carried into the first processing station 1, and when the processing is completed, it is carried into the second processing station 2.

The workpiece A completed at the second machining station 2 is
is transferred to the third processing station 3 by a loader device 8 according to the present invention.

First, the loader device 8 is guided by the guide rail 12 and
The lower member 8b of the loader main body 81 is lowered to a predetermined height by the lift cylinder 36, and the lower end of the centering arm 13 enters into the workpiece A, for example, homo a.

Next, the centering cylinder 19 operates, and the movable bracket 2
When the centering pad 15.15 at the tip of each centering arm 13.13 comes into contact with the workpiece A, the positioning of the workpiece A is completed.

that time. The movable bracket 2 is adjusted according to the shape of the workpiece A.
0 and the lever 17°1 linked to the centering arm 13.13
Adjustment bolt 18.1 interposed between the end of 7
By adjusting the length of 8, the center position of the gripping center of the workpiece A by the centering pads 15 and 15 at the tips of the centering arms 13 and 13 is moved to the right or left, and the reference position of the workpiece A is adjusted. It is.

Following the positioning of the workpiece A by the centering arm 13.13, when the clamp cylinder 33 operates, the tips of the clamp arms 14.14 located on both sides of the workpiece A are closed, and the tips of the clamp arms 14.14 are closed. The protruding clamp pads 29 and 29 enter, for example, a through hole in the workpiece A.

Clamp workpiece A.

In this state, the lift cylinder 36 raises the lower member 8b of the loader main body 81 together with the workpiece A.

The workpiece A is positioned with respect to the processing station 3 by being transported along the guide rail 12 to the next processing station 3, lowered to a predetermined height by the lift cylinder 36, and carried into the processing station 3. This eliminates the need for operations such as positioning the workpiece A each time the workpiece A is brought in and then starting machining the workpiece A, as in the conventional method.

As described above, the loader device according to the present invention includes an upper member 8a that is movable along the guide rail 12, and an upper member 8a that is movable along the guide rail 12.
A loader main body 81 consists of a lower member 8b which is vertically movable by a lift cylinder 36 attached to the loader body 81, and a loader body 81 is swingably attached to the lower member 8b via a rotating shaft 1616 so as to be able to grasp the workpiece A. A pair of centering arns 13.
13 and.

levers 17, 17 each having one end fixed to the rotating shaft 16.16; a centering cylinder 19 for opening and closing the pair of centering arms 13.13 attached to the lower member 8b; Adjustment bolts 18 whose lengths are adjustable are interposed between the tip of the piston rod 19a of the cylinder 19 and the other end of each lever 17.17.
18, and at least a pair of gripping arms 14 swingably attached to the lower member 8b so as to be able to clamp the workpiece A via (support) legs 27, 27 perpendicular to the rotation axis 16°16. .14, and a clamp cylinder 33 for opening and closing the pair of gripping arms 1414 attached to the lower member 8b and linked to the pair of gripping arms 14, 14 via links 31, 31. .

The length of the adjustment bolt 18°18 is adjusted according to the shape of the workpiece A, and the workpiece A is adjusted using the centering arm 13.13.
The position of the gripping center of the workpiece A can be adjusted by moving the gripping center position of the gripping arm 14.
If the workpiece A is further clamped and conveyed to the machining station by step 14, the workpiece A will be positioned on the loader side, so there is no need for a workpiece positioning mechanism for each machining station, and positioning operations can also be performed. This is not necessary at all, and this increases the operating rate of each machining station and improves work efficiency at the same time.Since the workpiece loading position can be adjusted on the loader side, it can be adjusted on the machining station side each time. There is no need to do this, and adjustment operations can be carried out efficiently, especially when the workpiece changes into various shapes.

In addition, the workpiece has a pair of centering arms 13 that are orthogonal to each other.
．． 13 and at least one pair of gripping arms 14, 14, the grip is firm and there is no danger of the work falling.
