Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is mainly used for an apparatus capable of uniformly forming a film layer of coal tar or a paint-based water leak prevention material for the purpose of preventing water leakage inside a metal vase. This invention relates to a rotary chuck that can rotate on its axis and revolve around it, allowing it to easily and conveniently attach and detach vases of various shapes, regardless of the size of the vase, and also enable speed change, stop, and reverse operations for rotation and revolution. be.

The present invention will be explained below with reference to drawings of one embodiment.
Reference numeral 1 denotes a rotary chuck according to the present invention capable of rotation and revolution, 2 a circular chuck plate that can be directly connected to the rotation and revolution axis 3, and 7, 7, 7 the circular chuck plate 2.
Or, if only one of the chuck gears 4 rotates, or if the circular chuck plate 2 and the chuck gear 4 rotate in opposite directions, the protruding pins 6, 6, 6 provided on the chuck gear 4 are used as fulcrums, In addition, guide grooves 8, 8,
A chucking arm 1 that can be geometrically interlocked by sliding protruding pins 5, 5, 5 provided on the circular chuck plate 2 within 8;
0, 10, 10 are springs provided between the circular chuck plate 2 and the chuck gear 4 so that an elastic force acts in a direction that causes the circular chuck plate 2 to rotate clockwise; 11 is the spring 10, 1;
The vase is held on the circular chuck plate 2 through the chuck pieces 9, 9, 9 at the tips of the chuck arms 7, 7, 7 using elastic force of 0.10. Reference numeral 12 is a switching arm operation unit for operating the opening and closing of the tracking arms 7, 7, 7, and reference numeral 13 is a switching arm operating unit for operating the piston unit of the hydraulic or air cylinder 17 while the rotation and revolution axis 3 is stopped. By tightening and rotating the chuck gear 4, the chuck arms 7, 7,
7 is a rack gear for opening and closing the front end of the chuck gear 4; 15 is a fitting type sliding case for avoiding reaction when the chuck gear 4 is rotated by a hydraulic or air cylinder 17 via the rack gear 13; and 16 is a fitting type sliding case. a spring for always pushing up the rack gear 13 toward the hydraulic or air cylinder 17 within the mating sliding case 15;
Reference numeral 14 designates a guide rod that is directly connected in the moving direction of the rack gear 13 in order to obtain the directionality of the spring 16, and 18 represents a support hole of the guide rod 14. In the drawings, bearings 19, 20, and 21 are provided to enable smoother operation between the circular chuck plate 2 and the chuck gear 4.

Next, the operating procedure of the present invention will be explained with reference to the drawings. FIG. 4 shows a state in which the rotation and revolution axis 3 is stopped, and the tracking arms 7, 7, 7 are closed because the hydraulic or air cylinder 17 is contracted. FIG. 5 shows that the piston portion of the hydraulic or air cylinder 17 has been extended by an electric signal or the like from the state shown in FIG. A vase 11 is placed on the chuck board 2 on the inner circle. FIG. 6 shows a state in which the piston portion of the hydraulic or air cylinder 17 is contracted again by an electrical signal or the like from the state shown in FIG. 5, and as the piston portion contracts, the rack gear 13 is 16 and the springs 10, 10, 10 push up the vase 11 on the circular chuck plate 2 due to the elastic force of the springs 10, 10, 10. 7, 7 are held in place via chucking pieces 9, 9, 9. FIG. 7 shows a state in which the rotation and revolution axis 3 starts operating from the state shown in FIG. It is possible to start the revolution after a certain time delay after the start, or to start the rotation after a certain time delay after the start of the revolution, or to operate only the revolution while stopping the revolution, or to arbitrarily select the direction of the rotation and the revolution of the revolution axis 3. During the rotation and revolution, a film layer of coal tar or paint-based water leak prevention material can be formed inside the vase 11 for the purpose of preventing water leakage. Next, after forming a film layer of coal tar or a paint-based water leak prevention material in the vase 11, the rotation and revolution axis 3 is adjusted to the sixth position.
After returning to the same position as shown in the figure, the rotation and revolution axis 3 is stopped by the next electric signal or the like. Next, the hydraulic or air cylinder 17 is operated again using an electric signal or the like to move the tracking arm 7,
After opening 7 and 7, if the vase 11 on the circular chuck plate 2 is replaced with the vase 11 to be used for the next operation, the same state as that shown in FIG. 5 will be obtained, and the above operations can be repeated in sequence.

Since the present invention is constructed as described above, the number of revolutions, revolution speeds, or revolution angles can be adjusted electrically or by using a rotary pulse generator to suit vase sizes of various shapes and sizes. It is a device that can be easily and arbitrarily adjusted by a control device called ``Vase'', and can automatically inject an appropriate amount of dissolved coal tar or paint-based water leak prevention material into the vase. In combination with a device that can be detachably inserted into and taken out of the device, it can be made into an integrated automatic system device. In addition, in the case of the above embodiment of the present invention, the periphery of the bottom of the vase body is gripped, but as shown in FIG. 8, by deforming a part of the circular chuck plate and chuck gear, It can be modified as desired, such as by grabbing the upper part. In addition, in the case of the above embodiment of the present invention, a rack gear type driven by hydraulic pressure or an air cylinder was used to open and close the chucking arm, but an arbitrary type such as a fan-shaped gear type as shown in FIG. Variants available. Furthermore, in the case of the above embodiment, a pair of rotary chucks that can rotate and revolve around each other and a chucking arm operation part are used as a pair, but it is possible to combine a plurality of rotary chucks that can rotate and revolve around each other and one chuck. It is possible to further enhance its usefulness by using a continuous type of water wheel combined with a king arm operation part, or by selecting and modifying it to suit various purposes other than those shown in the above embodiments. It can also be provided at a relatively low cost.
