Schunk to show new products at MACH
Automation and gripping technology supplier, Schunk will be showing a variety of new products on Stand 5079 in Hall 5.
The company recently entered a strategic partnership with Vision & Control and will show the first products resulting from that cooperation at MACH 2008.
Recently presented in Europe at the Motek Show, the intelligent Vision Sensor SRV will be on show at MACH. This new product is a development from the Camat series of products from Vision & Control.
The SRV is a complete system that can be used without additional peripheral devices. It can be utilized for practically all tasks in industrial image processing, for example the inspection of workpieces, completeness checks in assembly automation, searching for parts or positioning axes and angles. For example, it can check mechanical components such as pins, rings, nuts or bolts if they are present.
The SRV performs assembly and feature checks, recognizes damage on edges, detects the position of fastenings and labels, sorts and removes defective components. In pick & place applications, it ensures that parts in all kinds of rotary positions and even limp objects such as cables and hoses are safely gripped.
In addition to the camera and lens, the compact housing of the SRV also accommodates LEDs and an evaluation unit with all the necessary software and interfaces. In the simplest case, you only have to connect the sensor to a power supply and teach it using two keys.
Alongside the SRV, Schunk will be introducing the new size 60 Beta series of linear axes, thereby providing even finer graduation in its program of precise linear modules. An important prerequisite for selecting the best axis solution in terms of cost and performance the Size B 60 is intended for economical axis applications with high demands on dynamic and smooth running. It features a precise profiled rail guide and can be operated both by a ball-screw spindle drive with supports and by a robust, play-free toothed-belt drive with adjustable belt tension.
The version with ball screw drive is designed for a high driving force of 4000N and attains travel speeds of up to 2.5m/s with a maximum stroke of 5120mm thanks to the spindle supports. Acceleration values of up to 20m/s² are possible with a repeat accuracy of +/- 0.03mm. By comparison, the version with toothed belt drive attains a high driving force of 850N and covers distances up to 7620mm at speeds up to 5m/s. The maximum possible acceleration is 30 m/s² with a repeat accuracy of +/- 0.08 mm.
Schunk will show the new polyamide gripper fingers and adapter plates. Manufactured in a laser forming process by LMD, a technology partner of Schunk the components feature very complex geometries that cannot be produced by metal cutting technologies. The complex air feed-through can be routed through a one-piece workpiece in all three dimensions without having to set bore holes from the outside.
Also on display will be the PGN-plus and PZN-plus grippers. Ideal for situations where long fingers and high gripping forces often stand in conflict with the requirement of having compact sizes of the gripper housing, this exciting new range offers innovative solutions to this problem.
The grippers are equipped with a precise multi-tooth guidance. Forces and moments of the gripper are spread over several surfaces of a multiple-tooth guide, enabling longer fingers. The base jaws are precisely adjusted into the housing (0.01mm) in order to achieve a low guide clearance and to minimise wear.
The base jaws are synchronised by a stable wedge hook mechanism, which is guided via surface contact. The required forces are achieved by a pneumatic piston whilst the gripper offers a range from 2mm to 35mm stroke per finger. The PGN-plus 2-Finger-Parallel-Grippers are available in 8 sizes to cover a range of gripping forces between 140N and 13,000N. Additionally, the PZN-plus 3-Finger-Centric-Gripper is offered in 7 sizes offering gripping forces from 580N to 38,700N.
Each gripper can be ordered in a heat resistant or corrosion-proof design, with or without internal / external acting spring pressure for additional clamping force or safety facility and also in combination with a dust cover or with a spring operated pressure plate. Taking these exciting workholding solutions to new heights, Schunk has extended its portfolio with the new PZV 4-Finger Concentric Gripper - the latest addition to the exceptional product range.
Whilst two and three finger-grippers cater for most industrial handling tasks, 4-finger-grippers are required in instances where cylindrical workpieces are magazined on one level. Whereas three finger-grippers have at least one finger that would always collide with neighbouring components, the PZV profits in spacious circumstances with its four fingers.
The 4-finger PZV is the ideal gripper module for holding coplanar and cylindrical workpieces at a high positioning accuracy. Even at other applications, the PZV convinces with its high degree of flexibility. It can be used as a parallel gripper for clamping with two different pairs of top jaw fingers without problems and without having to set-up the fingers. As a result the set-up times can be permanently optimised – without interrupting the running operation.
