Abstract

The present invention relates to an adsorption magnetic force automatic switching device of the magnetic adsorber associated with the patent application No. 2001-29018 filed by the applicant.

In the above-mentioned prior application, the rotational angle of the ratcheting operation panel described above is 90 degrees as the rotating disk connected between the operation of the actuator rotates forward and backward in the range of 90 ° to convert the NS polarity of the rotating magnet to turn on and off the attracting magnetic force. In the first operation, the adsorption magnetic force is prepared for the adsorption, and in the second operation, the adsorption is carried out (ON). In the third operation, the adsorption is prepared for the OFF. Since the city is in the OFF phase of the adsorption magnetic force, this is not only an uncomfortable defect in operation, but such an operation device protrudes out of the body, resulting in poor merchandise and easy contact with other objects. There was a defect that caused a safety accident such as a malfunction.

The present invention has been invented to solve the above problems, the gist of the present invention is to install the automatic opening and closing drive of the adsorption magnetic force in the interior of the body (1) to prevent the closed end of contact damage with other objects and the simultaneous working body The operating range of is 90 ° and the rotational range of the rotating magnet is 180 ° so that when it is tensioned and released by the crane, the primary tension is the adsorption force of the attracting magnetic force (ON) and the secondary tension of the crane's tensile tension. At the time of tensioning, it becomes the OFF phase of the adsorption magnetic force, thereby increasing the operational simplicity and safety.

The cogwheel 11 is installed in the inside of -1 so as to be rotatable by the shaft 12, but the latch 10 is integrally formed by the fastening bolt 10-1 on the left and right sides of the cogwheel 11. On the outside of the left latch 10, a latch boss 9 fixed to the shaft 12 by a key 12a is provided, but the plate 9-1 fastened to the latch boss 9 is provided. When the actuator 13 is rotated clockwise to the latch 10, the main gear 11 is rotated at the same time as the shaft 12, and when the counterclockwise rotation is rotated in the left latch 10, I'm One right latch 10 is provided with a right flange 8, which is fitted to be rotated to the shaft 12, and the right flange 8 is mounted on the shaft 6 of the support 6 by a fastening bolt 8-2. The plate 8-3 fastened to the part 6-1 and fastened to the inside of the right flange 8 is locked to the right latch 10 when the actuator 13 rotated counterclockwise, In the direction of rotation, the right latch 10 is made to slide.

7 is a separate embodiment of FIG. 3, the main gear 111 and the driven gear 111-2 fitted to the shafts 112 and 112-2 have the same tooth number, and are idle at the shaft 112-1. The interlocking gear 111-1 is fitted so that the number of teeth thereof is 1/2 of the driven and driven gears 111 and 111-2.

The present invention configured as described above is an adsorption magnetic force automatic opening and closing device of the magnetic adsorber, when carrying out this, by placing the adsorber body 1 on the object such as a steel plate to be transported by using a crane and then releasing the tension of the crane (13) is rotated 90 degrees counterclockwise as shown in Fig. 5a by its own weight so that the operation period 13-1 is in a horizontal state, at which time the actuator 13 as shown in Fig. 5b by using a crane ), The plate 9-1 of the latch boss 9 fastened to the shaft 12 is caught by the latch 10 fastened to the left side of the cogwheel 11, and the cogwheel 11 By rotating 90 ° clockwise, the interlocking gear 11-1 interlocked therewith rotates the driven gear 11-2 rotating the rotating magnet case 5-1 at 180 ° while being co-rotated. Accordingly, the driven gear 11-2 having the number of teeth of 1/2 that is interlocked with the interlocking gear 11-1 as the main gear 11 and the interlocking gear 11-1 having the same teeth are rotated by 90 °. As the polarity of the fixed magnet 5a and the rotary magnet 5 becomes NN and SS while rotating at 180 °, the suction magnetic force is turned ON. Next, when the tension of the crane is released, the actuator 13 is rotated 90 degrees counterclockwise as shown in FIG. 6A to be horizontal, but in this case, the actuator 13 is attached to the right flange 8 fastened to the support 6. The plate 8-3 is engaged with the right latch 10 fastened to the cogwheel 11 to prevent reverse rotation of the cogwheel 11 and at the same time the left latch 10 fastened to the opposite side is latch boss ( Since it slips on the plate 9-1 of 9), the adsorption magnetic force is kept ON. Therefore, the adsorption state of the object to be adsorbed, such as an iron plate, is also maintained. And when the crane is lifted again to release the adsorption magnetic force after the end of the transport, at this time, as the actuator 13 is rotated upward and vertical as shown in Figure 6b, the rotating magnet 5 is rotated by 180 ° while the fixed magnet As the polarities of 5a and the rotating magnet 5 are changed to NS and NS, the magnetic field does not extend below the magnetic pole member 2, so that the adsorption magnetic force is turned off. Therefore, the suction magnetic force is turned on at the time of the primary tension tension of the crane, and the suction magnetic force is turned off at the time of the secondary tension tension. When the adsorption magnetic force is turned ON or OFF, the polarity separating portion 5-3 of the rotating magnet case 5-1 is slightly (5) in the direction of the action of the suction magnetic force with the nonmagnetic material 2-1 of the magnetic pole member 2 (5). It is inclined, and the rotating magnet 5 does not rotate reversely and is safe.

And when the number of teeth of the main gear 111 and the driven gear (111-2) as shown in Fig. 7 and the number of teeth of the interlocking gear (111-1) idle idling to 1/2 is installed the actuator 13 ) Is the preparation stage of the adsorption magnetic force when the primary operation (when the tension of the crane is released first) is 90 °, and the adsorption is performed when the actuator 13 is operated in the secondary operation (when the tension of the crane acts primarily). When the magnetic force is in the ON state, when the actuator 13 is in the third operation (when the tension of the crane is released in the second phase), it is in the preparation stage of the release of the adsorption magnetic force, and when the operation 13-1 is operated in the fourth operation (the crane When the tension of the secondary acts), the adsorbed magnetic force is turned off. Therefore, even if the main gear 111 and the driven gear (111-2) to the same number of teeth and the number of teeth of the interlocking gear (111-1) is idling can be achieved as described above.

As described above, in the present invention, an opening and closing device for automatically turning on and off the suction magnetic force is installed inside the body 1, and the rotating magnet case when the tension of the crane applied to the actuator 13 is primarily tensioned. When (5-1) is rotated 180 ° clockwise, the adsorptive magnetic force is turned on, so that an object such as an iron plate can be transported in the air, and when the tension of the crane is secondly tensioned after transportation, the rotating magnet (5). ) Rotates 180 ° continuously in the clockwise direction, so that the suction magnetic force is turned off. Therefore, the actuator 13 is not only easy to operate, but also the actuator 13 is installed inside the body 1 to prevent damage from other objects. It is a very useful invention because it can greatly contribute to the prevention of safety accidents, such as no risk of malfunction of the switchgear.
