Abstract

The integrated working head consists of a supporting part, composed of a clamping pin (2), a console (1), a carrier (3), completed with a set of energy distribution and connection elements, and an active part containing an electromagnetic gripper. The solution enables a combination of active parts and their connection with the supporting part into a single unit.<IMAGE>

Description

CS 274 030 Dl

The present invention relates to an integrated working head in which the properties required for gripping, holding and tearing a technologically related group of compacts in the process of in-process handling are uniform.

In the automation of sheet metal forming technology, inter-operative manipulation, which reduces the method of manufacturing sheet metal parts, is irreplaceable. Inseparable part of the sheet metal forming automation is the robotization, which creates in this technology specific conditions resulting mainly from the properties of the handled parts.

Suction heads are used for gripping flat-formed molded parts, which use successive perfect elements of vacuum heads as active parts. Concurrently with the commencement of the use of suction heads, attempts were also made to utilize the electromagnetic working heads.

Working heads contain! active parts which in shape correspond to the compact which is transferred by means of them. They are designed for one type of molding, eventually larger assortment, which does not exceed the scope of large-scale production and the field of hard automation. Working heads sd simultaneously equipped with the presence detection of the compact.

In order to increase the flexibility of automated production systems, it is also necessary to solve the working heads to suit several types of moldings. The problem is solved by constructing universal wide-range grippers, so that active parts are adjustable on the working head. However, adjusting them extends the disassembly of the workplace to another type of molding, since the active parts need to be adjusted to specific moldings with respect to their positioning and sensing their presence. However, this does not meet the requirement of flexibility for rapid exchange and automatic replacement, which significantly speeds up and streamlines the alignment of automated production systems to a different range. Therefore, there is a realization of the idea to perform an automatic exchange, eventually a rapid exchange of special working heads and the same clamping part corresponding to the end member of an industrial robot. However, the solution of the head system is always conditional on a specific application example. cations. ¹

With the gradual transition of robotics to the field of flexible manufacturing systems, the theory of group technology, analysis of component basic technology and technology leading to the identification of a technologically related group of components becomes important. From the point of view of gripping, holding and dropping the moldings in the process of in-process handling in sheet metal forming technology, a possibility exists for a technologically related group of parts to unify the properties of the work heads that would otherwise be addressed for each particular molding into one integrated work head.

The integrated working head consists of an actuating part and an actuating part comprising an electromagnetic gripper. The solution enables the combination of the active parts and their connection with the carrier part in one unit.

In the attached drawing, FIG. 1 shows a plan view, FIG. 2 is a front view and FIG. 3 shows a side view of the integrated working head according to the invention.

The integrated working head comprises a support part, which consists of a clamping pin 2 for its attachment to the end boat of the manipulator or robot. The bracket 8 is fastened to the flange of the clamping pin 8 by means of the clamping elements 18. In it is help

CS 274 038 B1 clips 7 and bolts 22 gripping power supply 12 terminated by connector 17. The opposite supply line leads through the power supply 14 to the terminals 19 mounted on a support 3 which is fastened to the bracket 1 via a washer 6 by means of connecting elements 20 and The carrier 3 has a holder 13 of the sensor 16, which has induced time (jc protected by the top cover).

The active part of the integrated working head is fastened to the universal carrier part of the integrated working head by means of fastening elements 13. Each working part of the working head consists of an electromagnet 11 fixed by fastening elements 21 to a clamp 2.

The invention finds application mainly in robotized workplaces where it serves as a technological head. By its principle, the division of the whole into a universal carrier part and a special active part is uniform, usable in various variations of design according to the specific case of application.
