Hereinafter, a preferred embodiment of the horizontal level adjusting device of the carriage of the vertical looper of the present invention will be described with reference to the accompanying drawings.

1 is a basic conceptual perspective view for explaining the principle of the present invention, Figure 2 is a front view showing the main part of the looper and the carriage of the present invention, Figure 5 is a layout of the pulley and the upper adjustment mechanism mounted on the roofer top of the present invention 6 is a carriage plan view showing an arrangement of a pulley and a level mounted to the carriage of the present invention.

The basic operation principle of the vertical looper is that in the lower roll installed in the looper body 10 and the upper roll installed in the carriage 20, the upper roll periodically spaces the lower roll through the periodic vertical movement of the carriage 20. As it widens and narrows, the strip is repeatedly stored and discharged for a certain time.

1, the wire drum 41 is attached to the output shaft of the gear reducer 40, and the wire rope 42 is wound on the outer peripheral surface of the wire drum 41. As shown in FIG. As the gear reducer 40 repeats the forward rotation and the reverse rotation, the wire rope 42 wound on the wire drum 41 is wound, and the unwinding operation is repeated. Carriage 20 to which the rope 42 is connected is moved vertically as necessary to operate the vertical looper.

At this time, the weights 18a and 18b are installed on the left and right sides of the carriage so as to smoothly move up and down in response to the load of the carriage 20, and support and move the weights 18a and 18b. In order to facilitate the vertical movement of the carriage 20 according to the principle of the pulley, the weight pulleys 12a and 12b are mounted one by one on the left and right sides of the roofer body 10.

The wire drum 41 is wound with two wire ropes 42, one of which is along the drive side pulleys 13a, 13b, 13c1, and 13c2 of the upper side of the looper body 10. After winding on 21a1) 21a2, one end is fixed to the upper adjustment mechanism 11a on the upper part of the looper body 10, and the other one line is the working side pulley 14a, 14b (upper part of the looper body 10). 14c1 and 14c2 are wound around the work side pulleys 21b1 and 21b2 of the carriage, and one end thereof is fixed to the upper adjustment mechanism 11b on the upper part of the looper body 10. 2, 5 and 6, it can be seen that the pulleys and the upper adjustment mechanisms 11a and 11b are arranged in which arrangement state.

In the pulley configuration, the conventional pulley configuration is that the wire rope 42 is one-wound, so that it is double-wound so that adjustment to finely extend or shorten the length of the wire rope 42 is possible. It is preferable that the pulley is configured of a plurality of pulleys, each of which is installed in the carriage 20 and the upper part of the looper, respectively, so that the pulleys are not fixed to each other and are rotatable separately.

FIG. 3 is a conceptual diagram illustrating a reviving mechanism of the present invention, in which the pulleys are subjected to an operation process. First, referring to a pulley connection configuration of a driving side wire rope 42, a wire drum ( 41, a double winding of the carriage drive side pulley 21a1, the drive side pulley 13c1, the carriage drive side pulley 21a2, and the drive side pulley 13c2 passing through the drive side pulleys 13a and 13b at the top of the looper. After going through the process is fixed to the upper adjustment mechanism (11a). In the case of the working side wire rope 42, the carriage side side pulley 21b1, the side side pulley 14c1, and the carriage side side pulley (the carriage side 14a, 14b in the upper part of the looper in the wire drum 41). 21b2), after going through a double winding process of the work side pulley 14c2 has a configuration that goes through the process of being fixed to the upper adjustment mechanism (11b).

Figure 4 is a plan view of the upper adjustment mechanism of the present invention, a simplified configuration of the upper adjustment mechanism (11a) (11b) is shown, one end of the wire rope 42 is the turnbuckle bolt 15 of the upper adjustment mechanism It is fixed to one end of the), and when the turnbuckle 16 is rotated, the turnbuckle bolt 15 is rotated so that the wire rope 42 can be adjusted in the longitudinal direction. In particular, in the quadruple pulley structure in which the pulley is composed of double windings of up and down angles as described above, when the turnbuckle 16 is rotated four times, the length of the wire rope 42 is about four times the pitch of the turnbuckle bolt 15. Since a change occurs and the quadruple structure is used, the vertical displacement of the actual carriage 20 brings about a change of 1 times the pitch of the turnbuckle bolt 15, thereby enabling precise and fine horizontal adjustment.

3 and 6 shows the installation position of the precision leveler 30, the precision leveler 30 can be selectively applied irrespective of the type, the carriage upper and lower guide roller (22a) ( The required precision can be selected according to the span H (see Fig. 2) of 22b. [0038] In more detail, as shown in Figs. 3 and 6, the precision level 30 is a carriage 20; Is provided at the center of both sides of the side, i.e., at the side or the upper surface of the carriage 20 corresponding to the installation position of the carriage driving side pulley 21a1 and 21a2 or the carriage work side pulley 21b1 and 21b2. Since the side pulleys 21a1 and 21a2 and the carriage work side pulleys 21b1 and 21b2 are installed at the positions where the carriage 20 can be best maintained in the vertical, horizontal, horizontal directions, It is most important to measure, and the present invention is also wound around the pulleys. Fine adjustment of the rope (42) is because a feature to adjust the left and right horizontal view of the carriage 20.

The adjustment values of the upper adjustment mechanisms 11a and 11b corresponding to the measurement angles of the precision leveler 30 may be obtained by calculation or empirical measurement. 11a) and 11b to display the fixing position on the side of the turnbuckle bolt 15 so as to be identified, and empirically measuring the rotational speed and the rotation direction of the turnbuckle bolt 15 corresponding to the angle deviation of the precision leveler 30 It is desirable to use it as a diagram, attach it to a looper, and use it.

The present invention is a device that allows the measurement and adjustment of the tilt of the carriage roll axial direction that causes strip meandering in the vertical looper during operation. It is possible to secure. This is an important point that sets the standard for looper operation and operation.

Also, in setting the equipment operation and maintenance standards, the level control of the carriage can be adjusted at any time by the precision level indicator during operation, thereby reducing the tension deviation of the wire rope resulting from the mismatch between the center of gravity of the carriage and the city center. It can be minimized to extend the life of the plant and to extend the replacement cycle of the plant concerned.

In addition, the carriage tilt can be adjusted at any time, thereby reducing the maintenance time. In particular, it is possible to obtain the basic data for determining the stability of the steering unit when operating the device, which will determine the required quantity of the steering device in the future looper design, whether there is a need, and the manufacture, installation and design accuracy of the auxiliary device. It is a very useful invention because it serves as a standard for determining.
