Abstract

The H-shaped slider system allows a central sliding block (3) to move through the 'swept area' described by the length of the primary (7) and secondary (4) slider beams. The central sliding block (3) can be modified to carry vacuum, pneumatic, mechanical or electrical gripping or holding devices for pick and place robotics. The central sliding block (3) could also be fitted with a carrier plate on which items may be placed and transported through the 'swept area' described by the lengths of the primary (7) and secondary (4) slider beams. The motors (10&11) are mounted in fixed positions relative to the slider beams (7&4) and a single toothed belt (1) is used to move the central sliding block (3). There is no requirement for flexible cableways or umbilical cable lines to drive the central sliding block (3) through the 'swept area' described by the length of the primary (7) and secondary (4) slider beams.

Description

t, 1. M-SHAPED SLIDER MECHANISM
The use of orthogonal slider systems is common where pick and place packaging or placement systems are used. Typically when a toothed belt driven system is employed each axis has an independent toothed belt drive and this results in one of the axis drives being carried with the slider that it is operating.
If the primary axis slider is carrying the secondary axis slider beam as well as the secondary-axis drive motor linen the primary axis motor must be increased in size to overcome the mass and inertia of the secondary motor being carried. The problems of providing the power supply to the drive motor that is being carried are usually overcome by the use of flexible cableways or umbilical cables suspended above the device. This wastes space as it limits the maximum plan area through which the device can operate and the suspended power cables can be a potential safety hazard.
There are also orthogonal slider systems that have fixed motors and use a single toothed belt as in the invention but they are constructed in a cross shape with the motors mounted each end of the primary slider beam and the toothed belt terminating at one end of the secondary slider beam. Because the secondary slider beam is carried In the X configuration by the primary slider the effective movement of the central sliding block is restricted to about 50% of the total swept area of slider movement.
The nvcntion uses a single toothed belt ( I) to move the central sliding block (3) in both the.sccondary and primary directions while both drive motors ( 10) and ( I I) arc mounted in fiend positions on the primary slider mounting plates (is) so there is no requirement tor flcxibic cable ways or umbilical cable lines. Because of the unique method of utilising the belt path the device is space efficient and it maximises the total swept area as the slider configuration describes an H. A description of the way the invention operates is supported by the accompanying
drawing as follows: FIGURE I shows an isometric view of the complete Hshaped slider mechanism.
As shown in Figure I the toothed belt ( I) is in one continuous length clamped at each end to the central shding block (3) by the toothed belt clamp (2). lithe spindles (20) are rigidly attached to the secondaryslider mounting plates (5) so following the bcit path clockwise the back face of the toothed belt passes around idler pulley (12) the toothed face passes around drive pulley (13) the toothed lace passes around the tension pulley (14) the back face passes around idler pulley (15) the back trace passes around idler pulley (16) the toothed face passes around tension pulley (17) the toothed face passes around drive pulley (18) the back face passes around idler pulley (19) the belt attaches to the other side of the central sliding block (3) and is retained by the toothed belt clamp (2).
2. The central sliding block (3) is free to slide backwards and forwards along the secondary-
axis slider beam (4). The secondary-axis slider beam (4) has mounting plates (5) at each end and these are rigidly attached to the primaryslider blocks (6). The primary-slider blocks are free to travel backwards and forwards along the primary-axis slider beam (7) these primary-axis slider beams (7) have mounting plates (8) and (9) at the ends and these are rigidly attached to a base plate or machine frame.
To move the central sliding block (3) backwards and forwards along the secondary-slider beam (4) drive motor I (10) and drive motor 2 (11) must be rotated in the same direction at the same speed.
To move the secondary-slider beam (4) backwards and forwards along the primary-slider beam (7) drive motor 1(10) must be rotated in the opposite direction to motor 2 (11) at the same speed.
It is therefore possible to move the central sliding block (3) in any direction within the swept area' described by the length of the secondary (4) and primary (7) slider beams with a combination of motor rotations t'rom motor I ( 10) and motor 2 ( 1 1)

Claims (1)

  1. 3. CLAIMS
    1. An H-shaped slider system with two axes of movement where the primary axis is formed by two parallel sliders and the secondary axis is formed by a third slider bridging across between the two parallel sliders and with a central sliding block mounted on the secondary shder and driven by a single length of toothed belt with both ends of the belt fixed to the central sliding block. 2. An H-shaped slider system as claimed in claim I in which the single length of toothed belt passes round eight pulleys of which four are placed at the ends of the two parallels forming the primary axis, two further pulleys are placed at one end of the secondary axis and the final two pulleys are placed at the other end of the secondary axis.
    3. An H-shaped slider system as claimed in claim 1 in which the central sliding block can he moved parallel to both the primary and the secondary axes by two motors mounted in fixed positions relative to the primary and secondary sliders. 4. An H-shaped slider system substantially as described herein with reference Lo figure 1 of the accompanying drawing.
