Abstract

The device for automatic handling of ferromagnetic materials is intended for handling large-area sheets. It relates to the field of lifting and handling equipment. The essence lies in a movably mounted hoist on a horizontal guide profile and in a vertical arm, which is slidable in the vertical direction, connected to the hoist, while a rotating unit is mounted on the lower part of the arm, on which there is also an electromagnetic plate, with which the large-area ferromagnetic sheet is clamped.

BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a device for the automatic handling of ferromagnetic material, especially large-area sheets. The presently known manipulation devices for manipulating large-area plates are designed as manipulators of pneumatic, hydraulic, or ro-shoe type. These devices are relatively complex when, for example, the clamping of the large surface area by means of pneumatic suction devices, the use of electro-pneumatic elements is required to introduce an automatic working cycle, a vacuum generating device is needed to increase the overall operating costs. and maintenance of these devices.

Other disadvantages, such as pneumatic manipulators for handling sheet metal, are that their carrying capacity is relatively low, the sheet metal grip is made from a constant position, the number of working pneumatic cylinders is limited and the larger built-up area is also disadvantageous.

The above-mentioned disadvantages are partly eliminated by the device for automatic manipulation with spheromagnetic materials according to the invention formed by the support part and the guide profile, on which the device is movably mounted, the principle of which is that the arm is slidably mounted on the pulley with at least one second end a stroke switch, wherein a rotatable unit is fixed to the lower part of the arm, which is fixedly connected to the electromagnetic plate.

On the upper part of the rotary unit there is a fixed housing in which the cartridge is movably mounted, which is fixed at one end with at least one third terminal of the lower stroke limit and the second cone is fixedly connected to the hoist chain. Furthermore, at least one fourth end deactivation switch is fixed to the rotary unit. Locking elements provided with first end position switches are provided on the guide profile, in front of which the sprocket is formed by a spring-loaded pawl. An advantage of the device for automatic handling according to the invention is its simplicity of construction. Other advantages are the reduction of the costs of technological operations in the processing of ferro-magnetic materials and in workplaces equipped with this type of manipulator, which can successfully record manual work with large-area sheets.

The construction of the device ensures the clamping and unfastening of the large-area sheet by means of an electromagnetic clamping plate, with the possibility of carrying out strokes in the vertical and horizontal axes, as well as allowing the large sheet to be turned according to the set program. All information is in the form of an electrical quantity, which allows easy automation of the device.

In the accompanying drawings, an exemplary embodiment of an apparatus for the automatic handling of ferromagnetic materials according to the invention is shown, wherein in Fig. 1 is an elevation and in Fig. 2 is a side view of this device.

The device for automatic manipulation with ferromagnetic materials is formed from the supporting part 1, on which, on the one hand, a pulley-machine 5 equipped with a spring-loaded latch 15a is mounted in the guide file 6 and on the other hand the locking elements 7 carrying the first limit switches 8 of the position are displaced there. An arm 4 provided with a second stroke limit switch 9 and a rotary unit 3 on which the electromagnetic plate 2a is mounted and the fourth rotary limit switch 13 is mounted to the pulley 5 is slidably coupled.

The chain 14 of the hoist 5 is fixedly connected to the hub 10 slidably mounted in the housing 12, which is mounted on the upper part of the rotary unit 3. On the hub 10 a third limit switch 11 of the lower lift limit is fixed.

During the operation of the device for automatic handling of ferromagnetic materials, according to a predetermined program, by removing the chain 14 of the hoist 5, the arm 4 with the rotary unit 3 and the electromagnetic plate 2 moves downwards. By fitting the electromagnetic beam 2, the plate 18 moves the cartridge 10 in the housing 12 and the pulse of the third lower limit 11 of the lower stroke command commands the chain 14 to interrupt unwinding of the electromagnetic beam 2 by the electromagnetic field to the large area plate 18 and then winding it up the chain 14 by the hoist 5, thereby raising the arm 4.

By lifting the arm 4, the second stroke switch 9 is depressed, its pulse is commanded to interrupt the winding of the chain 14 and the chain hoist 5 starts to move along the guiding profile 8. The moving chain hoist 5 moves its first position switch 8 in its path, its pulse stops the moving device 5 , whose working position, by engaging the spring-loaded pawl 15, into the groove of the locking element 7 and at the same time begins to unwind the chain 14.

Also, the pulse of the second limit switch 9 of the stroke makes it possible to actuate the rotating unit 3 and thereby to rotate the electromagnetic plate 2 with the large surface area 18 by an angle which is limited by the pulse of the fourth limit switch 13.

The pulse of the third low limit switch limit switch 11 also allows the electromagnetic field 2 to be canceled and thus unfasten the sheet 18 from the electromagnetic beam 2.
