Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a positioning device 1t suitable for a hanging tool, particularly a container hanging tool.

[Conventional technology]

As shown in Japanese Utility Model Application Publication No. 54-49374, a container hoist is used to lift a container by engaging twist lock bins of the hoist with four hanging points on the top surface of the container. In order to engage the four twist lock pins at the four eight points, a hanger positioning device is provided at four points of the hanger.

When alignment is required, the positioning device causes the flipper located directly above the hanging tool to protrude downward outside the side of the hanging tool so that it can come into contact with the container. If alignment is not required, the flipper is raised and positioned directly above the hanging tool.

As shown in FIG. 1 of the above-mentioned publication, a rotating cylinder is used to drive the flipper, and as shown in FIG.
There is a rotating cylinder system that rotates the cylinder. Furthermore, as shown in FIGS. 2 and subsequent figures, there is a link system using parallelogram links and cylinders.

[Problem that the invention seeks to solve]

The rotating cylinder method described above uses a rotating cylinder and is therefore expensive.

The above-mentioned link method is relatively inexpensive, but since the flipper moves up and down almost vertically, the amount of lateral protrusion from the hanger is small.

There are two ways to use the flipper for alignment:

One method is to project the flipper to the lowest position and then lower the hanging tool.

The other method is to protrude the flipper halfway and stop the flipper operation, then lower the flipper using a hanger, and if the flipper hits the container, resume the lowering of the flipper to shorten the distance between the pair of flippers. This method involves moving the hanger laterally and positioning the hanger directly above the container.

However, this latter method is difficult with the above two systems.

That is, in the rotating cylinder type, the flipper rotates around the rotating cylinder, so the flipper can protrude laterally. Therefore, alignment can be performed using the latter method, but since the output of the rotary cylinder is small, this method cannot actually be used. Increasing the output of a rotating cylinder increases its cost.

Further, since the link method has a small amount of lateral protrusion, this method cannot be practically adopted.

SUMMARY OF THE INVENTION An object of the present invention is to provide an inexpensive positioning device that can provide sufficient force to move a hanging tool.

[Means for solving problems]

In the present invention, a flipper is rotatably provided on a first shaft, a cylinder device is used as a drive source for the flipper, a second shaft is provided that is rotated by the cylinder device, and the second shaft and the first shaft are connected to each other. The rotation angle of the first axis is set to the second axis.
This is characterized by the installation of a speed increasing device that increases the rotation angle of the shaft.

[For production]

Since the flipper is rotatably provided and a cylinder device is used as the lever, the output is large and the hanging tool can be moved laterally. Further, since the speed increasing device is provided between the cylinder device and the flipper, a large rotation angle of the flipper can be obtained with a small amount of movement of the cylinder device.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

Twist lock pins 2 are provided at the four corners of the main body 1 of the hanger. An alignment device is installed in this corner. Reference numeral 11 denotes an L-shaped flipper, which is composed of two L-shaped arms 11 a and a guide 11 b at the tip thereof, and rotates in the vertical direction around an axis on the upper surface of the main body 1 . When the flipper 11 is rotated upward, it is located within the projection plane of the main body l of the hanging tool (that is, directly above the hanging tool). Small sprockets 14, 14 are attached in parallel to the inside of the two arms 11a of this flipper 11. Flipper 11. The small sprocket 14°14 is fixed to the shaft center. The axis is supported on the upper surface of the main body l with a bracket 15°15.

Two large sprockets 18, 18 are rotatably attached to a shaft 19 at the center of the main body l. (9), 20 is axis 1
This is a bracket that supports 9 on the main body 1. One point on the outer periphery of the two large sprockets 18°18 is connected by a pin n. This pin n has the tip 25 of the rod of the cylinder device 2.
a is rotatably connected. The cylinder device section is installed vertically, and its cylinder side is fixed to the main body 1 with pins 5b. The cylinder device 5 moves the rod linearly. The ring is a chain 2, and the ends 26a and 26b of the chain 2 are fixed to large sprockets 18 and 18. The part where the chain is not applied to the large sprocket 18 is notched.

In such a configuration, when the cylinder device 5 is operated,
The large sprocket 18 rotates, and the small sprocket 4 rotates through the chain. This causes the brim 11 to rotate. When the rod of the cylinder device 5 is extended, the flipper 11 is lowered, and when the rod is retracted, the flipper 11 is lowered.
l increases.

Combining the large sprocket 18 and the small sprocket 14,
Since the small sprocket 14 and the flipper 11 are connected, the cylinder assembly B! Flipper 11 with a small movement of t25
A large rotation of 1'J is possible. Large sprocket, To1
8. The small sprocket 14 and the chain link constitute a speed increasing device.

If a lever (for example, a flipper) and a cylinder device are connected and the cylinder device is operated, the lever can rotate about 100 degrees. However, it is difficult to achieve a rotation angle larger than this. In the present invention, the lever (flipper 11
) and the cylinder device 1I25, the rotation angle of the flipper 11 of about 170 degrees can be obtained.

In addition, since the flipper 11 rotates around the axis,
It can be made to protrude to the side. Further, it can be easily stopped at the position indicated by the dashed line in FIG. Then, when it comes into contact with the container 5 at that position, the cylinder is installed! ! !
By retracting the rod B, the main body l of the hanging tool can be moved to the container 5 side. If a cylinder unit W125 with a large diameter is used, the necessary force can be outputted sufficiently. Since the stroke of the cylinder device 5 can be made small, it can be made inexpensive even if the diameter is large.

In the above embodiment, the chain handle is fixed to the large sprocket 5, but the chain handle may be hung through the sprocket. A belt, rope, etc. can be used instead of a cheno. Also, although two Cheno sprockets are provided on the shaft, one may also be used. Further, the number of arms 11a may be one. Alternatively, the shaft 19 and the shaft center may be connected by gears to increase the speed.

〔Effect of the invention〕

According to the present invention, with a cylinder device having a small stroke,
A large rotation angle of the flipper can be obtained, and the hanging tool can be moved during the positioning operation. Further, since a normal cylinder device can be used without using a rotary cylinder, effects such as being inexpensive, strong, and easy to maintain can be obtained.
