On the other hand, the base of the table 80 is spline-fitted to the upper part of the support shaft 1.

The table 8 fitted into the spline 9 of the support shaft 1 is moved up and down on the support shaft 1 by driving the rotor of the hydraulic cylinder IO, and horizontally rotated by the rotation of the support shaft.

A head 12 is provided on the table 8 and is capable of horizontal movement control Il1wJ using the idle rail 11 as a guide.

The head 12 is connected to the rear end of the table 8 through a rod 14A of a hydraulic cylinder 14 whose base is supported by a pin 13, and is moved back and forth on the table 8 by driving the hydraulic cylinder 14.

The head 12 is shown in an enlarged side view in FIG. 3, in FIG. 4 a section taken along line IV-IV in FIG.
As shown in the enlarged cross-sectional view of the line part, one support 15 is installed upright, and cam plates 1 are installed on the left and right sides of the support 15.
6.16 meeting is fixed.

The cam plates 16, 16 have outer surfaces 16a, 16& formed into inclined surfaces that extend downwardly and outwardly.
At the center of the outer surfaces 16a and 1fia, the outer surfaces 1
Inclined shafts 17 and 171 whose axes are orthogonal to 6a are implanted.

#The oblique shaft 17.17 supports a lever rod 19, IQ via bearings 18, 18.

The lever rods 19, 19 have their longitudinal intermediate portions aligned with the inclined axis 1.
7 and 17, respectively, and nail plates 21 and 21 are fixed to the upper edge of the distal end to which the horizontal member side arm of the hanger on which the article 5 is suspended can be hung.

On the other hand, a horizontal shaft 22 passes through the rear end portions of the levers 19, 19.

The horizontal shaft 22 has both left and right ends inserted through inclined bushes 23, 23 attached to lever rods 19, 19K, and in the center is a rod 25A of the hydraulic cylinder 5 supported by a bracket 24 attached to the upper part of the column 15. It is fixed to the tip of the.

The endless conveyance equipment 6 has a tire 27 suspended from a tire 27 running as a guide on a rail 26 with a flange 26A horizontal and a way 7'-26B vertical, and the tire 27 is moved by pulling it with an endless chain. However, endless conveyance equipment having other structures may be used.

Note that the symbol hole in the figure is the prime mover.

Since the present invention has the above-described configuration, when the hydraulic cylinder 25 is driven and the rod 25A is pulled up, a horizontal line passing through the rear ends of the left and right lever rods 19, 19 as shown in FIG. As the shaft 22 is pulled up and the tip is lowered, the spacing between the claw plates 21, 21 at the tip increases.

This will be explained with reference to the principle diagram shown in FIG.

When the levers 19.19 are horizontal with the tilting axes 17, 17 as fulcrums L7, the outer surfaces 16a of the camdeleys 16, 16.

Located along the top of 161L, 1qA, 19 in the figure
The tip exists at the position indicated by A.

When the rear ends of the levers 19 and I'-1 are pulled up by the operation of the hydraulic cylinder 25, the levers 19 and 19 move toward the inclined shaft 17.
, 17 maintains a constant distance between the central portions in the longitudinal direction, but the portions nearer to 1 beyond the inclined shafts 17 , 17 are outside at the lower end portions of the cam plates 16 , 16 . 16a, keeping parallel to lfi &, so
The tip portions are located at 19B, 19BK &, and the opposing distance expands from (@ to (n) shown in FIG. 6).

The opposing distance between the claw plates 21 and 21 expands from (→ to (n)), but the expansion rate is equal to the outer surface 16a of the cam plate t6.16.

The angle (θ) formed by rod 16a and rod 25A (Figs. 3 and 5)
(see figure) is determined by the stroke.

Next, an example of the operation of transferring the article 5 from the conveyance line (B) to (0) will be explained with reference to FIGS. 7 (=L) to (1).

First, when the article 5 that has been moving in the direction of the white arrow on the conveyance line (B) reaches ft5-1, just before reaching the device (A) of the present invention, the hydraulic cylinder IO is actuated and the table 8 The head 12 is moved forward by the hydraulic cylinder 14 while the rear ends of the levers 19 and 190 are pulled up by the hydraulic cylinder 5, and the hanger 20 is moved forward by the hydraulic cylinder 14.
The middle part of the lever faces between the tips of the levers 19 and 19.

As the rear end portions of the lever rods 19, 19 are raised, the tip portions are expanded, and the distance between the opposing claw plates 21, 21 is widened, resulting in the dimensions (nl) shown in Fig. 6. This means that the rear end portions are closer to each other as much as the front end portions are expanded.

The displacement caused by the approach of the rear ends of the lever rods 19 and 19 is absorbed by sliding the inclined bushes 23 and 2 on the horizontal shaft 22, as shown in FIG. 7(b).・N levers 20 to 1!'l
, 19, and at the same time the lower part of the hanger 20 is exposed between the tips of the levers 19, 19, the hydraulic cylinder 25 is operated to close the levers 19, 19.
is horizontal, and as shown in Figure I@1, move the claw plates 21, 21 horizontally to the lower surface of the member 20A. During this time, move the support shaft 1 to the lower surface of the member 20A. ) is rotated in the direction shown by the arrow inside, corresponding to the speed of the endless conveyance equipment 6.

The state shown in FIG. 7 (0) is a state in which chucking is completed, and the lever 20 is sandwiched between the tips of the levers 19, 19.
In addition, the horizontal member 20A is supported by the claw plates 2 and 21.

From this state, the table 8 is raised completely by the operation of the hydraulic cylinder l (+), the head 12 is moved backward by the operation of the hydraulic cylinder 14, and the rotational speed of the table 8 is increased.
- The head 20 floats up and comes off the hook 7, continues to rotate the table 8, moves the head 12 backward, and moves the article 5 to the middle position as shown in FIG.

Then, by rotating the table 8, the position of
As shown in Figure (e), when the head 1 reaches position 5-1, which is beyond the position directly horizontal to the conveyance line (0),
2 toward the tip of the table 8 and connect it to the conveyance line (C
) wait for the hook (in Figure 7).

Hook of transport line (0) (transfer line (B) in Figure 1)
) is detected, and at the 9th hour, the table 8 is started in reverse and lowered as shown by the arrow in FIG. 7(f), and the hook 7 is engaged with the hook 20.

Next, raise the rear ends of the levers 19, 19 to open the gap between the claw plates 21, 21, and further increase the rotation speed of the table 8 (Fig. 7(g)).The table 8 continues to rotate. Then, as shown in FIG. 7, the article 5 is transferred to the conveyance line (0) and sent in the direction indicated by the white arrow in the figure.

During this time, the table 8 continues to reverse rotation as shown in Fig. 7 (1), and eventually returns to Fig. 7 (a) when the tips of the levers 19 and 19 pass directly across the conveyance line (B) and transfers the next article. I look forward to it.

FIG. 8 shows how the hanger A) is separated from the hook 7 in four stages.

Thereafter, by sequentially repeating the same operation, the article 5 is transferred from the transport line (B) to the transport line (0).As explained in this embodiment, the transport line (0) is transferred to the transport line (0).
It is also possible to use the conveyor line in the opposite direction rather than in the same direction as B)0Also, it is not necessarily necessary to make both conveyor lines (B) + (0) parallel, but if they are too close together, there will be no room for movement. . Furthermore, it is also possible to distribute or selectively transfer from the transport line (B) to a plurality of transport lines.

As is clear from the above description, the article clamping, lifting and discharging device of the present invention can reliably clamp, lift and discharge articles, and the inter-in article transfer device, which includes this device as a main part, can transfer articles between different lines. It can be performed reliably, and in particular, it has excellent effects such as easy linkage with a computer.
