Abstract

An industrial robot for handling workpieces and tools consists of gantry beams (2) mounted on supports (1) on opposite sides of a rectangular working area, the beams (2) being spanned by a crossbeam (4) provided with carriages (3) received for movement along the beams (2). The gantry beams (2) are relatively short and the crossbeam (4) relatively long. A gantry carriage (5) moves along the crossbeam. A lifting device (6) and a grip (7) are mounted on the gantry carriage (5). A limiting arrangement is provided to maintain equal rates of movement of the carriages (3) along the gantry beams (2). <IMAGE>

Description

SPECIFICATION Industrial robot for handling workpieces and tools The invention relates to an industrial robot of cross gantry design for handling workpieces and tools.
Known industrial robots of cross gantry design, i.e.
with a rectangular working area, are constructed such that the crossbeam is moved with the gantry carriage, which means that the entire mobile mass of the robot is moved, whereas the gantry carriage, which has a relativelysmall mass, hasto coverthe shorter distances.
The disadvantages of this kind of industrial robot of cross gantry design lies in the fact that a high power supply must be installed to drive the crossbeam, in orderto obtain speed and acceleration values resulting in transport times which areaccept- able for the distances to be covered.
An object of the invention is to optimise the situation regarding material expenditure for an industrial robot of this kind, drive power and transport times.
Another object of the invention is to construct an industrial robot of cross gantry design such that particularlythe shaft extending in the longitudinal direction ofthe rectangular working area can be moved at a high speed with a reasonable drive power and with a high degree of reliability.
These objects are solved according to the invention as follows. The cross gantry is designed such that the cross beam ofthe industrial robot is extended so that the gantry carriage, which has a relatively small mass, has to coverthe long distances within the working surface, whereas the entire crossbeam only covers the shorter distance. The synchronism of the two carriages of the crossbeam is preferably monitored by two limit switches, between which a switch lever is rotatably mounted. Should irregularities occur in the transverse movement, i.e. inadmissible advance or lagging of one ofthetwo carriages, the switch lever is pressed against one ofthe limit switches, according to the direction of devi ation,thus causing an immediate braking action.
Thus, broadly stated, the present invention provides an industrial robot including cross gantry beams, a crossbeam extending betweenthegantry beams and secured to carriages mounted for movement along the gantry beams, the aspect ratio between the gantry beams and the crossbeam being greaterthan one, and a gantry carriage movable along the crossbeam.
In orderthatthe invention may be morefullyunderstood an embodimentthereofwill now be described by way of example with reference to the accompanying drawings on which Figure 1 is an overall view of an industrial robot and Figure2 shows a device for monitoring the movement ofthe crossbeam.
Figure 1 shows an industrial robot of cross gantry design with foursupports 1 and two gantry beams 2, on which the two cariages 3with the crossbeam 4are moved. The carriages 3 are mounted on rollers on the guideways ofthe gantry beams 2. The guideways of one of the gantry beams 2 are formed as a V-way; thoseoftheotheroneasaflattrackto balancedistancetolerances. The gantry beams 2 are relatively short and the crossbeam 4 is relatively long, i.e. the aspect ratio between the gantry beams and the crossbeam is greaterthan one.
The gantry carriage 5 is guided on the crossbeam 4 and is provided with a lifting device 6 and a grip 7.
The crossbeam 4 is driven on each carriage 3 by a direct-current motor, which is not shown, and a rackand-pinion gear. The two direct-current motors are electronically synchronised.
The synchronism of the two carriages 3 is additionally monitored by a device shown in Figure 2. Two limit switches 9 are arranged on a holder 8 on the carriage 3 guided in the V-way, between which switches a switch lever 10 is rotatably mounted. A switch rod 11, rotatably secured to the crossbeam 4, connects the switch lever 10 to two adjustable stops 12.
Irregularities in the movement of the crossbeam, i.e. inadmissible advance or lagging of one of the two carriages 3, lead to a slight deviation between the crossbeam 4 and the carriage 3 guided in the V-way.
This results in a relative movement between the switch rod 11 and the holder 8, and the switch lever 10 is pressed against one of the two limit switches 9, depending on the direction of deviation. An emer gency cutout which is thereby triggered slows down the crossbeam drive.
The solution according to the invention enables an industrial robot of cross gantry design to be constructed such that particularly the shaft extending in the longitudinal direction of the rectangularworking surface can be moved at a high speed with a resonable drive power. The situation regarding material expenditure, drive power and transporttimes can be substantially optimised.
1. An industrial robot including cross gantry beams, a crossbeam extending between extending between the gantry beams and secured to carriages mounted for movement along the gantry beams, the aspect ratio between the gantry beams and the crossbeam being greaterthan one, and a gantry carriage movable along the crossbeam.
2. An industrial robot according to claim 1 including first and second motormeansfordriving the carriages respectively along the gantry beams, and means for controlling the relative driving rates of the motors.
3. An industrial robot according to claim 1 or2 wherein one of said carriages is received in a Vshaped channel on one ofthe gantry beams.
4. An industrial robot according to any preceding claim wherein two limit switches are secured to a holder on one ofthe carriages, between which switches a switch rod operated by differential movement of the carriages, actuates the limit switches.
