Special Conveyors

Belt conveyors for special requirements

Special tasks require individual solutions. For this reason, we also produce special belt conveyors for use in image processing systems and metal-free environments, and for conveying applications using vacuum and magnetic technology.

Vacuum conveyors

Belt conveyor with vacuum body for lightweight products

Vacuum conveyors can be used to convey lightweight products very quickly and reliably. They are particularly suitable for securing products, thus preventing lifting or tipping. They are also suitable for conveying products while suspended in order to close gaps, enable camera detection or pick up and set down products.

The conveyor frame is equipped with suction nozzles for a vacuum pump (e.g. industrial vacuum cleaner or side channel blower). This creates vacuum along the entire length of the conveyor frame. The conveyed products are gripped through holes in the slide bed and in the belt located above it, and then conveyed with the belt. For a smooth transfer of the conveyed products, the belt infeed is usually equipped with a rolling knife edge.

A timing belt can also serve as a conveying medium instead of the belt. Unlike the belt conveyor, the positive drive mechanism allows the timing belt conveyor to run without slippage. If an image processing system is used, the individual images can be assigned to match the track path.

Translucent conveyors

Belt conveyor with back light unit for optical inspection system

Translucent conveyors are used in automated production to optically inspect workpieces. They allow for contactless, geometric measuring and position detection of conveyed products.

The conveyor has a back light unit and translucent (transparent) conveyor belt. The products are illuminated through the belt from below, creating silhouettes. With cameras and appropriate image processing software, the workpieces can thus be examined for material defects, incorrect positioning, completeness and contour deviations. They are used, for example, for pick-and-place tasks or OK/nOK analyses.

All mk belt conveyors can be equipped or retrofitted with a back light unit and corresponding belt. The back light unit includes powerful LED lighting and, if necessary, flash control for extremely short exposure times. Lighting and flash control provided by the customer can also be integrated. Compact belt conveyors with drum motors are particularly suitable for applications with limited installation space since they do not have any obstructing edges.

Magnet belt conveyors

Belt conveyor for conveying magnetisable parts while suspended

Magnet conveyors allow for position-oriented conveying of ferromagnetic piece goods over steep paths (up/down), vertically or while suspended. An overhead conveyor is ideal for dealing with large height differences or for picking up and setting down products, e.g. during container loading. Magnet conveyors are also ideal for implementing a turning station.

The permanent magnets are integrated in the conveyor frame of the belt conveyor. Their design can be adapted according to the specific requirements. Magnetisable material is thus securely fixed to the conveyor belt thanks to magnets contained in the track. The conveyor geometry can be optimally adapted to difficult track layouts and installation situations. Even in curved belt conveyor segments, position-oriented, suspended conveying can be ensured. In addition to belt conveyors, flat top chain conveyors are also used, in which the magnets are embedded in the plastic chain links.

Metal-free conveyors

Belt conveyors for use in metal-free zones

“Metal-free” conveyors are used where metal in the conveyor might interfere with the defined magnetic fields of an application, for example in metal detectors for the food industry, CTs (computed tomography) or during the final magnetisation of materials.

Since a conveyor cannot be made completely metal-free, the critical areas are replaced by non-metal alternatives. For example, the slide bed can be replaced by a carbon slide bed and the supporting frame can be bridged by a CFRP profile. The supporting frame can also be removed in special cases. In addition to belt conveyors, modular belt conveyors are also particularly suitable for this purpose.

A special type of metal-free conveyor is the X-ray conveyor. It is used to X-ray products, especially for series inspections or automated processes, such as checking battery cells for internal defects. In this case, the X-ray plate is located inside the conveyor frame below the belt. The products are X-rayed lying on the belt and checked for internal defects. In addition to a metal-free slide bed, it is important to note that no antistatic belts may be used since they have cords that interfere with the image during the X-ray process.

Scanning conveyors

Belt conveyors with integrated systems for reading and writing data

A scanning conveyor is used when a large number of products have to be quickly identified during conveying. This allows, for example, automatic sorting to take place afterwards, or the end of a batch to be detected during production.

The conveyor has a flat RFID or magnetic strip scanning unit inside the conveyor frame. The goods to be conveyed require an RFID memory chip or magnetic strip in order to be identified in the scanning unit. Depending on the application, multiple items can be scanned in stacks, e.g. in the automated book return station of a library. Additional barcode readers can also be installed.
