More than 60 years of experience and continuous technological progress have made KOCH a worldwide leading manufacturer of machinery for better woodworking.
The core competence of the company concentrates on joining technology. Innovative technologies in Sawing, Shaping, Drilling, Gluing, Doweling and WoodWelding®.
Co-exhibitor LEHBRINK SpezialmaschinenGmbH has been part of the Koch Group since 2005. LEHBRINK specialises in the manufacturing of machinery for the processing of doors, door frames and folding back panels.
At this year's LIGNA, the focus of the exhibition was on the presentation of the new MULTIFLEX machine type and the topic of automation. Together with partner Ulrich RotteAnlagen und FördertechnikGmbH, two different work cells were presented, demonstrating the flexible processing of small quantities and medium quantities in throughfeed.
In addition, there was an innovation table where innovations in the areas of joining technology, automatic dowel recognition in the dowel tool, glue pot with fill level indicator and much more were presented.
SPRINT with robot loading
The work cell consists of the SPRINT single-sided drilling machine and a so-called cobot(collaborative robot). Thanks to the cobot, the cell does not require any special separating protective devices such as safety fences. The precise loading, processing and removal of narrow parts is particularly special here. The SPRINT's horizontal and vertical drilling stations can be freely configured and retrofitted in a grid of 32, which significantly increases the machine's flexibility for future requirements. The SPRINT is ideally equipped for processing carcass furniture, drawers, frame parts and solid wood parts.
NEW - MULTIFLEX with robot loading
The second machining cell is a real novelty. For the first time, KOCH is presenting its newly developed MULTIFLEX machine model for flexible drilling and dowel processing of small to medium quantities. High productivity is nevertheless achieved, with up to 18 parts per minute being processed, depending on the drilling pattern. A new feature of the concept is that the individual machining units, drilling spindle, glue valve and dowelling tool, have been combined into one unit and are fixed in position during machining or move along the workpiece point-to-point. If the processing units are in a fixed position, they can be adjusted by motor according to a freely selectable pitch. The MULTIFLEX is primarily designed for drilling and dowel processing of carcass bases and narrow parts such as drawers and narrow parts. The throughfeed machine can either be integrated into production lines or, as will be shown at LIGNA, function as a work cell with automatic loading and unloading. Here, too, the robot connection is controlled by Rotte.
LEHBRINK
In addition to the tried and tested machines for processing doors, door frames and rear wall folding, the special machine manufacturer will be presenting further developments in the following areas:
- Compact door seal unwinding stations with feeding from a platform
- New compact assembly station: Three door fitting elements can be installed in a frame in just one machine: hinge pockets, strike plates and reinforcement plates for concealed door hinges
- Glue track monitoring together with Beckhoff
- Vacuum double pusher with vacuum pump for back panels
- Buffer toothed belt conveyor without fixed cams or lift-outs
- Chip extraction from processing supports by means of a chip-tight cable chain
