Embodiment Construction

[0024] This view shows a tie beam 10 on which two mass suction devices 12 are arranged, on which in turn a workpiece 14 indicated generally by a dashed line is arranged. The mass extractor 12 is movably mounted on the tie beam 10 and grips the shoulder under such that it is prevented from being lifted. In this case, the block gripper 12 can be moved manually or by means of a drive. On the upper side, the block sucker 12 has a suction cup 16 with a circumferential seal 18 , on which the workpiece 14 is arranged. The seal 18 surrounds a suction chamber 20 into which a suction opening 22 opens. If air is sucked out of the suction chamber 20 through the suction opening 22 , the workpiece 14 is fixed to the suction cup 16 and thus to the block sucker 12 by means of the negative pressure.

[0025] The tie beam 10 is formed substantially from two profiles 24 manufactured from aluminum extruded profiles, between which the lower section of the mass absorber 12 is accommodated and on ...

Abstract

The device has a block suction device (12) displaced at a tie beam (10) for holding a plate-shaped workpiece (14). An opened channel (28) i.e. hose guiding channel, is provided at the tie beam, and a hose transferring force is installed at the channel. An end of the hose is connected with the block suction device by an opened side of the channel, where the opened side is formed as a slot (46). The end of the hose comprises a connection nipple with a quick connector for the block suction device. A deflection section (36) is attached at the channel for deflecting the hose.

Description

technical field [0001] The invention relates to a device for fixing or gripping workpieces, in particular for fixing or gripping plate-shaped workpieces, the device has at least one tie beam, at least one tie beam is arranged on the tie beam and An upper movable mass picker for holding workpieces, wherein a channel open at least on one side is provided on the tie beam. Background technique [0002] In EP 0 687 521 A1 a device for securing workpieces is known, in which the workpieces are arranged on and gripped by a plurality of block grippers. The mass extractors are arranged on the tie beam, the mass extractors being travelable in a first direction. The block extractors must be supplied with vacuum, for which purpose the tie beams are provided with a complex channel system for supplying the vacuum. [0003] DE 19809280 A1 discloses a linear hose seal and a suction gripping device, in which a suction channel open on one side is closed by means of two inflatable hoses. As ...
