is connected to. Therefore, the left and right slider cylinders 74 are configured so that they can be simultaneously rotated from a horizontal position (not shown) to a vertical position shown in FIG.

This rotation is performed when the hanging hand 10 is held by the hand 72 and waiting, and when the new mold 16 comes to the position of the automatic hanging hand placement device 40, the hanging hand 10 held by the hand 72 is brought downward, Position it above the mold 16.

After the rotation has taken place, the piston of the slider cylinder 74 is extended and the hand 72 is lowered to minimize the drop height into the mold 16.

Next, the pushing device 94 and the tensioning device ff1oo will be explained.

The pushing device 94 includes a cylinder 96 and a pushing plate 98, which will be described later.
The tensioning device 100 is composed of a cylinder 102, a claw 104, etc., which will be described later.
This is for positioning the hanger relative to the mold.

As shown in FIG. 11, cylinders 90 (FIG. 11) are attached to both sides of the base 42, respectively.
A movable plate 92 is attached to the piston of each cylinder 90, and the movable plate 92 is moved by the piston of the cylinder 90 between a retracted position and a forward position as shown by dotted lines and solid lines in FIG. The movement of the moving plate from the retracted position to the forward position is performed after the mold 16 comes to the position of the automatic hanging hand rest device.

As mentioned above, when the hanger 10 is dropped onto the mold 16, the leg 14 of the hanger 10 should fit into the groove 18a of the recess 18, which is the correct storage position shown in FIG.
The arm 18 of the mold 16 is caused by the deviation of the fixed position of the table 32.
It may end up resting on either of the flat surfaces 1'8b on both sides of a. In such a case, the pushing device 94 moves the leg 14 of the hanger 10 resting on the flat surface 18b toward the groove 18a, which is the correct position, and stores it in the groove 18a. This is done by pushing the legs 14 of the hanger 10 inwardly with push plates 98 attached to the left and right cylinders 96 of the push device 94, respectively.

The tensioning device 100 is for positioning the hanging hand 10, in which the leg 14 of the hanging hand 10 is housed in the spring 18a, with respect to the mold 16 along its course 18a, without or using the pushing device 94. As a reference plane for positioning,
The inner wall surface of the vertical portion 20a of the L member 20 of the mold 16 is used. In the initial state in which the hanging hand 10 is housed in the arm 18a, the cylinder body 1 of the cylinder 102 of the tensioning device 100 is
As shown in FIG. 7 or FIG.
It is located on the side of the hanger main body 12.

In this state, when the piston of the cylinder 90 is retreated,
That is, when moved to the left in FIG. 11, the claw 104 is also moved to the left together with the moving plate 92, and the handle body 12 of the handle 10 is brought into contact with the vertical portion 20a of the L member 20 of the mold 16. This allows the positioning of the hanger 10 with respect to the mold 16.

Thereafter, the cylinder body 102 of the cylinder 102 is lowered and thus the claw 104 is lowered to allow passage underneath the mold, and the piston of the cylinder 90 is pulled to move the moving plate 92 into an initial retraction. Return to position.

The overall operation of the automatic hand-hanging device is summarized below.
The hanging hands 10 are placed on the alignment and moving device 52 in an aligned state. The hanging hand 10 placed thereon is sent forward by this aligning and moving device 52. The separating device 66 attracts one hanging hand 10 at the forefront of the alignment and moving device 52 with a magnet 68, moves it to an intermediate position, grips it with the hand 72, and places a new mold 16 on the automatic hanging hand placement device. Wait until you are in position.

When the new hanging hand 10 comes to the position of the automatic hanging hand resting device, the moving plate 92 provided with the pushing device 94 and the tension bag floo is advanced by the cylinder 90 and brought to the forward position (operating value W).

At the same time, the hand 72 of the separating device 66 is rotated by the rotating device W82, and the hand 72 is lowered to a lower position above the mold 16. Next, the handle 10 is further lowered by the slider cylinder 74 until it is just above the mold, and the hand 72 is opened to allow the handle 10 to fall onto the mold.

Next, the pusher 94 accommodates the hanger 10 in the groove 18a of the mold 16, and the tensioner 100 positions the hanger 10 relative to the mold 16.

Thereafter, the mold with the hanger placed thereon is moved to the next station by the turntable 32, and at the same time a new mold is brought to the position of the automatic hanger holder. The device is ready for the next cycle.

(Effects of the Invention) As described above in detail, the present invention can solve the problems of occupational safety and health and the problems of harmful effects caused by boring simple manual labor by providing an automatic hanging hand rest device.
