Description

[Detailed Description of the Invention] The present invention relates to a device for attaching a cap to the end face of a tube body.

For example, when lining the inner surface of an iron pipe with mortar or the like, a cap made of rubber or the like is attached to one end of the iron pipe, and this cap prevents the mortar from flowing out. Conventionally, this process of attaching the cap was carried out by manually striking the circumference of the cap with a wooden hammer, but this conventional method was laborious and inefficient, and also caused damage to the cap. There was a problem that it could not be pressed sufficiently against the end face of the iron pipe.

The present invention solves the above-mentioned conventional drawbacks and aims to provide an apparatus for attaching a cap to the end surface of a tube body, which can automatically and efficiently attach the cap to the end surface of the tube body.

In order to achieve the above object, the device for attaching a cap to the end surface of a tube according to the present invention includes a cart that is movable in the axial direction of the tube toward the end surface of the tube, and a dolly that is mounted on the cart and is mounted on the cart. a movable dolly that is movable in the same direction as the movable dolly; a drive device that is installed on the dolly and reciprocates the movable dolly via a vibration isolation device; a leaf spring having good flexibility in the direction of movement; a micro-vibration generator attached to the leaf spring; , a plate body that can come into contact with a cap temporarily fixed to the end of the tube body, and the plate body is caused to collide with the cap by the reciprocating motion of the movable cart by the drive device, thereby causing the cap to be attached to the tube body. The micro-vibration generating device vibrates slightly when the cap is pushed into the end of the tubular body by the driving device, thereby causing the cap to vibrate slightly. It is configured so that it can be attached to the end of the tube.

According to this configuration, the cap is temporarily fixed to the end face of the tube body, and the drive device causes the movable cart to reciprocate to cause the plate to collide with the cap a predetermined number of times, thereby pushing the cap into the end of the tube body. After that, by moving the moving cart using the drive device and operating the micro-vibration generator while pressing the plate against the cap, the vibrations generated by the micro-vibration generator are amplified by the elastic body and vibrate the plate, causing the plate to vibrate. Since the body presses the cap against the end surface of the tube while vibrating, the cap can be attached to the end surface of the tube automatically, efficiently and reliably.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a truck serving as a base that is reciprocated on rails 3 by a cylinder device 2. On this truck 1, there are a plurality of pairs of rails 4 parallel to the rails 3. A plurality of cylinder devices 5, which are fixedly installed and are made of air cylinders as driving devices, are installed, and a movable cart 6 is mounted on each pair of rails 4, respectively. This moving trolley 6 has wheels 7 made of urethane rubber that come into contact with the rail 4, and is connected to the piston rod of the cylinder device 5 via a vibration isolation device 8. They are forced to move back and forth. A pair of leaf springs 10 as elastic bodies are attached to the front surface of the movable cart 6 via a vibration isolating rubber 9, and a micro-vibration generator 11 is supported by the pair of leaf springs 10. The leaf spring 10 is arranged so as to have good flexibility in the moving direction of the movable trolley 6. On the front of this micro-vibration generator 11,
A plate body 12 is attached, and this plate body 12 is
Pipe body 1 carried in and carried out by a transport device not shown
It faces a cap 14 made of rubber or the like which is temporarily fixed to one end surface of the cap 3.

Next, the operation will be explained. First, the cylinder device 5 is driven to reciprocate the moving cart 6 a predetermined number of times, and the plate 1 is moved back and forth a predetermined number of times.
2 collides with the cap 14 a predetermined number of times to push the cap 14 into the tube body 13. Next, the cylinder device 5
While pressing the plate 12 against the cap 14,
The micro-vibration generator 11 is activated. The micro-vibration generated by the micro-vibration generator 11 is amplified by the plate spring 10 and causes the plate 12 to vibrate, and this vibration securely attaches the cap 14 to the tube body 13 as shown by the imaginary line. Thereafter, the micro-vibration generator 11 is stopped, and the cylinder device 5 moves the movable cart 6 backward. The tube body 13 with the cap 14 attached thereto is carried out by the conveyance device, and the next tube body 13 to which the cap 14 is temporarily attached is carried in by the conveyance device.
The same operation is repeated thereafter. The above operations are automatically performed by a control device (not shown).

In this way, the micro-vibration generated by the micro-vibration generator 11 is amplified by the plate spring 10 and the plate body 12 is vibrated to perform the final pushing of the cap 14. Therefore, even when the cap 14 is made of easily deformable rubber, However, the entire cap 14 can be brought into close contact with the end face of the tubular body 13, and the cap 14 can be quickly and reliably attached with a small amount of power. Further, since the cylinder device 5 is connected to the moving carriage 6 via the vibration isolation device 8, the influence of vibration can be reduced, and the occurrence of failures can be reduced. Furthermore, by moving the cart 1, it is possible to easily and quickly deal with a case where there are a plurality of types of tube bodies 13 with different tube end positions.

In the above embodiment, the cylinder device 5 and the micro-vibration generator 11 were not arranged on the same axis due to space constraints for miniaturization, but considering only the functionality of the device, it is possible to arrange them on the same axis. It is preferable to place it in

As described above, according to the present invention, the following effects can be obtained.

(a) After colliding the plate with the cap using the drive device and pushing the cap into the end of the tube,
Since the final pressing of the cap is performed by the micro-vibration generated by the micro-vibration generator, even if the cap is made of rubber that is easily deformed,
The entire cap can be brought into close contact with the end face of the tube body, and the cap can be attached reliably with a small amount of power.

(b) The micro-vibration generated by the micro-vibration generator is amplified by a leaf spring to vibrate the plate, and the final pressing of the cap is performed by the vibration of the plate, so it can be automatically and efficiently done with a small amount of power. Caps can be attached reliably.

(c) By moving the cart itself on which the movable cart is mounted, it is possible to easily and quickly deal with cases where there are multiple types of tubes and the tube ends are in different positions.

(d) Since the drive device is connected to the moving trolley via the vibration isolation device, the influence of vibration can be reduced and the occurrence of failures can be reduced.
