 The present invention relates to a gantry loader (Gantry Loader), and more particularly to a gantry loader equipped with a rotating device capable of rotating the workpiece 180 degrees.

In general, the gantry loader refers to a device that supplies a material to be processed in a CNC (computer numerical control) lathe or a machining center (hereinafter referred to as a 'machining lathe') and simultaneously performs a loading function.

1 is a simplified view of a general gantry loader, the gantry loader is a discharge lift 112 for loading the processed material (111a), the supply lift 113 for loading the material 111b to be processed, It has a discharge lift motor 114 and a supply lift motor 115 which drive lifts 112 and 113, respectively.

When the material 111b to be processed is placed in the supply lift 113, a supply waiting point confirmation sensor 116 is installed at the set stacking position SP of the material 111b to be processed, and is provided through a programmable controller (PLC) 121. Be aware.

The programmable controller 121 is controlled by the numerical controller NC 122.

The materials 111a and 111b loaded on the lifts 112 and 113 have been described as a centuri loader arm 133 having a discharge gripper 131 and a supply gripper 132 (here, a centuri loader arm). By using a loader arm mounted thereon) to a chuck (not shown) of the machine tool.

Here, when trying to process the opposite side (that is, the part of the machine tool chuck) of the processed material 111a, the processed material 111a is manually rotated 180 degrees from the loaded lift lift 112. . However, rotating the workpiece by hand by 180 degrees is inefficient in terms of yield.

In order to solve this problem, recently, two methods of using the gantry loader arm 133 to invert the workpiece are used. The method of use is described in FIG. 2 as follows.

Fig. 2 is a schematic diagram for explaining a mechanism for rotating the workpiece 180 degrees in the machining of both surfaces.

First, the A surface 210a is processed by the machine tool in the workpiece 210 bitten by the chuck 213 of the machine tool.

After the processing of the A surface 210a is finished, it is transferred to the first loader arm 211 (①). At this time, the portion clamped to the first loader arm 211 becomes the A surface 210a.

Next, it transfers from the 1st loader arm 211 to the 2nd loader arm 212 (2). At this time, the portion clamped to the second loader arm 212 becomes the B surface 210b.

Again, the portion that is transferred from the second loader arm 212 to the chuck 213 of the machine tool (③) and clamped to the chuck 213 of the machine tool becomes the A surface 210a. Therefore, the B surface 210b can be processed by a machine tool.

However, this method has a problem of using two loader arms. That is, there is a problem that the unit price of the loader arm itself is expensive, and two machines (industrial robots) to which the loader arm is mounted are required and are not efficient in terms of cost.

The material of the main body 400 is preferably a structural rolled steel, in particular SS41 (Structural Steel, tensile strength 41-52kg / mm ² ).

The rotating part 410 may include a guide bearing 411, a cam plate 412, a bearing housing 413, a first cam shaft 414, a cam 415, and a second cam. It comprises a shaft (Cam Shaft, 416).

The guide bearing 411 serves to guide the line through which the cylinder plate 422 is transferred along the piston 421 by receiving hydraulic or pneumatic pressure from a cylinder (not shown).

The cam plate 412 is responsible for determining a transfer path of the bearing housing 413 connected to the cylinder, the transfer path having a first straight path, a first ramp, a second ramp and a second straight path. Although only the four most preferred routes are mentioned here, it is also possible to add other routes. According to this path, the principle that the workpiece 433 rotates 180 degrees will be described in detail with reference to FIGS. 6A and 6B.

In the bearing housing 413, guide bearings 411 are inserted into both sides to facilitate transport, and a hole formed of a bearing is formed in the center thereof, and the second cam shaft 416 is seated in the hole.

The first cam shaft 414 is inserted into the cam plate 412 and is conveyed by the cylinder action of the cylinder along the conveyance path of the cam plate 412.

The first cam shaft 414 and the second cam shaft 416 are connected and interlocked by the cam 415.

The cylinder part 420 is a source for driving the conveyance and rotation of the rotating part 410. The cylinder part 420 is connected to the cylinder piston 421, the cylinder plate 422 connected to the cylinder piston 421, and the cylinder plate 422, and is connected to the bearing housing 413 to move up and down by a cylinder action.

Referring to FIG. 6, when pressure is applied due to a cylinder action of an external cylinder, although not shown, the first cam shaft 414 moves the first straight path 610a of the feed path 610 of the cam plate 412. The second cam shaft 416 is also interlocked by the cam 415, and moves straight along, and the finger plate 431 mounted on the second cam shaft 416 is also linearly moved (600A).

Next, as the first cam shaft 414 enters the first ramp 610b of the transfer path 610, the first cam shaft 414 moves along the first ramp 610b. Since the second cam shaft 416 lies on the same axis line between the first cam shaft 414 and the cam 415, the second cam shaft 416 is moved at an angle corresponding to the first inclination path 610b. As a result, the finger plate 431 connected to the second cam shaft 416 also rotates by the angle (600B).

Subsequently, when the first cam shaft 414 is positioned at the point where the first ramp 610b and the second ramp 610c meet, the finger plate 431 is rotated by an angle of 90 degrees with respect to the original position.

Referring to FIG. 7, a principle of rotating from the original position of the finger plate 431 in the 90 degree direction to the 180 degree direction is illustrated.

This can be explained by the same reason as in FIG. 6, and in 600C, the finger plate 431 is rotated 90 degrees from the original position, and in 600D, the finger plate 431 is moved to the rotated position by an angle between 90 and 180 degrees. Subsequently, at 600E, the position of the finger plate 431 is moved to the position rotated 180 degrees from the original position.

By the structure according to the present invention, the rotary device of the gantry loader can be usefully used when processing both sides of the workpiece.

Referring back to FIG. 4B, the workpiece 433 processed on one side is placed with the workpiece 433 shown in FIG. 4B by a loader arm (not shown) from a machine tool (not shown).

The upper surface of the workpiece 433 shown in FIG. 4B is a processed surface, and the lower surface is a raw surface.

The placed workpiece 433 is moved to a position rotated by 180 degrees as described in FIGS. 6A and 6B (433a).

In this case, the machined face is directed to the upper face and the machined face is directed to the lower face, whereby the machined face can be machined if the loader arm is clamped to the chuck of the machine tool.
