Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for connecting flexible piping to a moving body without excessive tension or slack.

In automatic machines used in various industrial fields, air cylinders, motors, etc. are often installed as actuators in moving objects.
When moving objects, it is inevitably necessary to connect air piping, cables, and other piping to the moving object. Conventionally, coil-shaped The common method was to use piping.

However, such a method is not preferable because there are restrictions on the stroke of the movable body, and there are also problems such as the expanding and contracting piping being damaged due to interference with nearby objects.

In this way, the present invention was devised in response to the fact that conventional devices had some practical drawbacks. In a device for connecting flexible piping to a moving body that reciprocates between By disposing it so that it can reciprocate from a set base point while maintaining parallelism with the moving body, and by linking the moving body and the moving body via a power transmission device having a gear ratio of 1:2, The traveling body is formed so that it can move in the same direction as the mobile body in synchronization and at half the relative speed, and the piping is connected from a fixed part provided between the starting point of the moving body and the base point of the traveling body. It has a hairpin-like configuration extending through the pulley to the connecting portion of the moving body.

However, by having such a configuration, the length of the hairpin-shaped path from the fixed part to the connecting part of the movable body via the pulley is always a constant value, so piping arranged along this path This invention is characterized by making it possible to stably connect flexible piping to a moving object without the inconvenience of causing excessive tension or relaxation. This will be explained in detail with reference to the embodiment shown in FIG.

Reference numeral 1 denotes a movable body to which an actuator in an automatic machine is attached, and flexible piping 2 such as an air hose extending from a fixed part 10 is latched to a connecting part.

This moving body 1 has an endless chain 13 that is slidably engaged with a rail 5 that extends straight, and is stretched between chain wheels 11 and 12.
By rotating one of the chain wheels 11 or 12 in the normal or reverse direction using an appropriate drive source (not shown), reciprocating motion within a predetermined stroke range between the starting point 6 and the turning point 7 is achieved. It is possible.

Reference numeral 3 denotes a running body which slidably engages with a rail 14 disposed in a parallel relationship near the rail 5, and a chain wheel 15.
, 16, and as the chain 17 runs, it can reciprocate while remaining parallel to the moving body 1.

The traveling body 3 is rotatably equipped with a pulley 4, and after the air hose 2 extending from the fixed part 10 is suspended on the pulley 4,
The hook is arranged in a hairpin shape leading to the connecting part of the moving body 1.

The movable body 1 and the traveling body 3 form a connected relationship in which the driving source is shared, and a gear 18 coaxially connected to the chain wheel 11 is used.
By using a simple power transmission device such as a gear device formed by meshing the chain wheel 16 with the gear 19 coaxially connected to the chain wheel 16, the above-mentioned linkage relationship is maintained.

The traveling body 3 slightly reaches the turning point 7 between the starting point 6 and the turning point 7.
Although it is caused to reciprocate between the base point 8 which is set on the opposite side and the reversal point 9 which is located outside the predetermined stroke 1 range on the side of the turning point 7, the gear ratio of the gears 18 and 19 and the chain wheels 11 and 16 By appropriately selecting the diameter ratio of the moving body 1, the traveling body 3 is formed so as to be able to move in the same direction as the moving body 1 in synchronization and at half the relative speed.

The piping connection device configured as described above connects the moving body 1 to the first
When traveling a predetermined stroke l from the starting point 6 position shown in the figure to the turning point 7 position shown in the second figure, the traveling body 3 moves by half the distance (1/21) from the relationship of the gear ratio and diameter ratio. It is natural to do so.

Therefore, the fixed part 1 of the air hose 2 is extended like a hairpin.
As is clear from the pulley principle, the length from 0 to the connection point remains unchanged, and therefore, regardless of the displacement of the moving body 1,
The air hose 2 is stably stretched without increasing the tension or loosening while maintaining the initial appropriate tension state, and air pressure can be introduced without any problem.

It goes without saying that the position of the fixing part 10 for fixing the air hose 2 is set at an intermediate position sandwiched between the starting point 6 of the moving body 1 and the starting point 8 of the traveling body 3.

Furthermore, the mechanism for linking the moving body 1 and the running body 3 is not limited to the gears and chain mechanism shown in the figure, but may also be capable of exerting a power transmission function with a gear ratio of 1:2. It is also possible to replace it with another device.

As is clear from the detailed description above, the present invention skillfully utilizes the principle of pulleys by combining a moving body 1 and a pulley 4 that moves in the same direction as the moving body 1 and at half the speed. 4, the length of the piping 2 stretched over the movable body 1 can be maintained unchanged. , moving object 1
It is possible to maintain a constant length without being affected by the running of the piping 2, and therefore, unlike conventional systems where tension and relaxation are repeated, the piping 2 does not interfere with other objects.
Furthermore, it can be installed under appropriate tension, resulting in no accidental damage, and provides an excellent effect of stably supplying fluid pressure, electric power, etc.

Furthermore, since the present invention utilizes a very simple pulley mechanism, the cost of the device is low and it has practical advantages such as being able to maintain smooth movement.
