Description

[Detailed explanation of the idea] This invention relates to an air blow device.

A conventional screw tightening device is shown in FIGS. 1 to 3.

That is, this screw tightening device, as shown in FIG.
Rails 2 are laid on both sides of the frame 1, which is framed in a rectangular shape.
Cart 3 with a drilling machine and screw tightening machine (not shown) attached
As shown in FIG. 2, it is possible to run on rails 2 via wheels 4.

Further, as shown in FIG. 3, a bogie braking air cylinder 5 is attached to the lower side of the bogie 3.

This air cylinder 5 has a clamp plate 6 attached to the tip of its piston rod 5a, and by supplying air from a braking air supply pipe 7, the piston rod 5a is contracted, and the clamp plate 6 is attached to the lower surface of the rail 2. Pressure contact and cart 3
At the same time, by supplying air from the brake release air supply pipe 8, the piston rod 5a is extended, the clamp plate 6 is separated from the lower surface of the rail 2, and the brake of the truck 3 is released.

On the other hand, as shown in FIG.
Three rows of conveyors 10 are arranged, and the conveyors 10 are driven and controlled by a motor 11.

Further, a fixed stopper 12 is arranged on one side of the conveyor 10, and a movable positioning plate 14 that moves forward and backward by a cylinder 13 is arranged on the other side.

Furthermore, a free roller conveyor 16 is disposed on the side of the gantry 1 and is driven horizontally and vertically by a horizontal drive shaft 15, and is driven by a cylinder 17.

The screw tightening work using this screw tightening device is carried out by first placing the free roller conveyor 16 horizontally as shown by the imaginary line in FIG. (not shown) is transferred onto the conveyor 10 via the free roller transport body 16.

When the panel frame is placed in the center of the frame 1, the conveyor 10 is stopped, and the movable positioning plate 14 is then driven forward to press one side of the panel frame and lock the fixed stopper 12 on the other side. to complete positioning of the panel frame.

Thereafter, the cart 3 is moved a predetermined distance along the rail 2, and a perforation machine (not shown) attached to the cart 3 forms holes in each of the panel surface plate and the panel frame. Tighten the screw to fix it.

In this case, the truck 3 is braked and stopped via the air cylinder 5.

In this way, the truck 3 is moved intermittently at a predetermined pitch, and screw tightening work is performed at each stop position, thereby completing all the screw tightening work of the panel surface plate to the panel frame.

After the work is completed, the cart 3 is returned to its original position, and the panel is transported to the next process by the conveyor 10.

However, this screw tightening device has a problem in that chips are generated when the panel frame and panel surface plate are drilled with a punching machine, and these chips adhere to the rail 2 and prevent the cart 3 from running smoothly. was.

This problem can be solved by preparing a new air blowing device and having the worker use it to blow air onto the rail 2 to scatter the chips from the rail 2. New problems arise in that the equipment is expensive and the spraying operation is complicated.

Therefore, an object of this invention is to provide an air blowing device that is inexpensive and can automatically remove deposits from rails.

An embodiment of this invention will be explained using FIG. 4.

That is, as shown in FIG. 4, this air blow device connects a branch pipe 18 by branching it from the middle of the brake release air supply pipe 8, and connects the branch pipe 18 with the pipe end 18a facing the rail 2 in front of the wheel 4. This is what was placed.

Since the other configurations are the same as those of the conventional example, the same parts are given the same reference numerals and the explanation thereof will be omitted.

As a result of this configuration, in order to run the trolley 3,
If air is supplied from the brake release air supply pipe 8 to separate the clamp plate 6 from the rail 2, a part of the air blown into the air supply pipe 8 will flow through the branch pipe 1B to the pipe end 18a.
Since the chips on the rail 2 in front of the wheels 4 are automatically scattered and removed as the truck 3 moves, the truck 3 can run smoothly.

Furthermore, compared to the conventional art, only the branch pipe 18 needs to be provided, and the manufacturing cost thereof is also low.

Furthermore, since the air for releasing the brake of the air cylinder 5 is used, the operating cost is also low.

Of course, while the truck 3 is stopped, air is supplied to the air supply pipe 7 but not to the air supply pipe 8, so air blowing from the branch pipe 18 can be stopped and waste of air can be prevented.

In the above embodiment, this invention is applied to a screw tightening device, but the present invention is not limited thereto.

As described above, the air blowing device of this invention includes a rail, a truck running on the rail, and a clamp portion attached to the truck and provided at the tip of the truck in conjunction with the expansion and contraction drive of the piston rod. A bogie braking air cylinder is compressed and separated from the bogie, and a branch pipe is branched from the brake release air supply pipe of this air cylinder and has its pipe end facing the rail in front of the wheels of the bogie. ,
It is inexpensive and has the effect of automatically removing deposits from the rail.
