Is also good.

Next, based on an example in which the transfer device 10 is used as a device for taking out a resin molded product as an example, the transfer device 1
The operation of 0 will be described with reference to FIGS. 1, 2, 4, and 5. The transferred object may be other than the resin molded product. First, the configuration of the take-out device 74 will be described with reference to FIGS. 4 and 5. The take-out device 74 takes out the resin product 78 resin-molded by the mold clamping device 76, and places the mounting tables 80 a, 8 on the left and right of the mold clamping device 76.
0b, which is a device to be transferred to either one of the 0b and 0b, is located above the mold clamping device 76, and is movable in the mold clamping / mold opening direction, and the movable body 82 is axially attached to the mold clamping / mold clamping device. It has an arm 84 that can swing in a direction perpendicular to the opening direction, and the transfer device 10 described above is attached to the lower end of the arm 84.

Next, the operation of the take-out device 74 will be described. First, the case where the resin product 78 is transferred onto the right mounting table 80a will be described. As shown in FIG. 1, the transfer device 10 uses the gear fixing screws 60 and the mounting bolts 74 to initialize the positional relationship between the rack 52 and the pinion 56 and the mounting position of the second restricting means. Also,
The rotation range of the rotating member 30 with respect to the main body 12 is approximately 90 in the arrow E direction from the state of the chuck device 46 in FIG. 1D.
Fixing bolt 2 so that it can be rotated within a range
4 is used to set the first restricting means. When the mold clamping device 76 is performing the mold clamping operation, the transfer device 10 is moved to the position F (the mold clamping device 7) shown in FIG. 4 by the arm.
6 (side of 6) (step 1), the mold clamping operation is completed, and when the mold is opened, the mold moves to the position G (step 2).
Next, the moving body 82 moves to the position H in the left direction in FIG. 4, and the chuck device 46 operates to sandwich the resin product 78 (step 3). Then, the moving body 82 returns to the position G again (step 4), and then the arm 84 swings to move the transfer device to the position F (step 5).
6 operates to release the resin product 78 (step 6), and the resin product 78 is transferred onto the mounting table 80a.

In this transfer, when air is supplied from the second joint 68 of the transfer device 10 into the second cylinder chamber 66 of the cylinder 14 in step 5, the valve bodies 50a, 5
The rack 52 moves to the left along with 0b, and the pinion 56 and the third bevel gear 58 rotate in the direction of arrow I accordingly.
The first bevel gear 18 rotates in the direction of arrow J. The rotating member 30, to which the second bevel gear 36 meshing with the first bevel gear 18 is fitted, rotates in the direction opposite to the pinion 56, so that the chuck device 46 holding the resin product 78 also moves in the direction of arrow E. Rotate. As a result, the upper surface of the resin product 78 faces upward. The first bevel gear 18 driven by the cylinder 14 tries to rotate further in the arrow J direction, but the rotating member 30 to which the chuck device 46 is attached rotates 90 degrees in the arrow E direction by the first restricting means. Since the rotation is restricted, when the first bevel gear 18 further rotates in the arrow J direction, the columnar member 22, the rotating member 30, and the chuck device 46.
Oscillates in the direction of arrow K about the first shaft 20 until the guide member 44 comes into contact with the stopper 72 in accordance with the rotation of the first bevel gear 18, and the resin product 78 held by the chuck device 46 becomes an arm. Together with the swing angle of 84, it becomes substantially horizontal, and it becomes easy to mount it on the mounting table 80a.

Next, the resin product 78 is placed on the left mounting table 80b.
The case of transferring is explained. The transfer device 1
If 0 is rotated 180 degrees with respect to the arm 84,
The resin product 78 is taken out from the mold clamping device 76 and placed on the mounting table 8
0b, the resin product 78 is placed with the upper surface and the lower surface thereof opposite to each other. Therefore, the transfer device 10 follows the procedure below and positions the rack 52 and the pinion 56 as shown in FIG. The relationship, the mounting position of the second restricting means, and the first restricting means are reset. The resetting procedure of the transfer device 10 will be described. First, loosen the gear fixing screw 60 to move the valve bodies 50a and 50b and the rack 52 to the left,
Tighten the gear fixing screw 60. Next, the mounting bolt 74 is loosened to move the stopper 72 to the position shown in FIG. Finally, the fixing bolt 24 is loosened, and the rotating member 30 is rotated 90 degrees in the direction of the arrow L in FIG. 2 to be fixed.

To explain the operation, the transfer device 10 is first located at the position M (side of the mold clamping device 76) shown in FIG. 4 when the mold clamping device 76 is performing the mold clamping operation by the arm ( Step 10), when the mold clamping operation is completed and the mold is opened, the mold is moved to the position G (step 11). Next, the moving body 82 moves leftward in FIG. 4 to the position H, and the chuck device 46 operates to sandwich the resin product 78 (step 12). Then, the moving body 82 is moved to the position G again.
Returns (step 13), the arm 84 swings, the transfer device moves to the position M (step 14), and the chuck device 46 operates to release the resin product 78 (step 1).
5) The resin product 78 is transferred onto the mounting table 80b.

At the time of this transfer, in step 14, air is supplied from the first joint 64 of the transfer device 10 to the cylinder 14
When it is supplied into the first cylinder chamber 62 of FIG.
The rack 52 moves to the right along with the valve bodies 50a and 50b, and accordingly, the pinion 56 and the third bevel gear 58 rotate in the direction of arrow O, and the first bevel gear 18 rotates in the direction of arrow P. . The rotating member 30 to which the second bevel gear 36 meshing with the first bevel gear 18 is fitted is rotated in the direction opposite to the pinion 56, so that the chuck device 46 holding the resin product 78 is also in the direction of arrow L. Rotate. As a result, resin products 78
The upper surface of is facing upward. The first bevel gear 18 driven by the cylinder 14 tries to rotate further in the direction of the arrow P, but the rotating member 30 to which the chuck device 46 is attached.
Is rotated by 90 degrees in the arrow L direction by the first restricting means, and then the rotation is restricted. Therefore, when the first bevel gear 18 further rotates in the arrow P direction, the columnar member 22, the rotating member 30, and the chuck device 46. Oscillates around the first shaft 20 in the direction of arrow Q with the rotation of the first bevel gear 18, and the resin product 78 held by the chuck device 46 becomes substantially horizontal.
It becomes easy to place on the mounting table 80b. Further, with the above configuration, the main body 12 is provided with the second restricting means for restricting the swing amount of the columnar member 22, and the columnar member 22 is rotatably attached to the first shaft 20 about the axis of the columnar member 22. Installed,
Since the chuck device 46 is rotatably attached to the rotating member 30, even when the resin product 78 held by the chuck device 46 is moved in the opposite direction,
The resin product 78 can be easily changed so that the resin product 78 can be transferred without being reversed.

Although various preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and the holding means is not a chuck device but a suction device or the like. It goes without saying that many modifications can be made without departing from the spirit of the invention, such as any device suitable for the object.

[0019]

When the transfer device according to the present invention is used, the held object to be transferred can be moved while being rotated by one driving means. Therefore, there are two driving means for moving and rotating the holding means. Since it is not necessary to provide the device, the structure of the device is simplified, and the device can be downsized and the product cost of the device can be reduced.
