Solutions for buffering & decoupling

Different cycle times between process steps create back pressure or idle time. Buffering and decoupling solutions compensate for these discrepancies, ensure a continuous production flow and make sequencing possible. Customers need space-saving systems with defined capacities, no back pressure and simple control integration.

Drängeltisch – Puffersystem aus Versaflex A08 und Modulbandförderern

Buffer products reliably and return them at low dynamic pressure

Re-circulation table - buffer system consisting of Versaflex A08 and modular belt conveyors: The re-circulation table serves as a buffer and overflow area for round, stationary products (cans, bottles, etc.) within a production line. In the event of bottlenecks in the downstream process, the products are collected, returned and then forwarded with reduced accumulation pressure. A Versaflex A08 hinged belt conveyor with a constant speed serves as the main line, flanked by an MBF P 2040 modular belt conveyor. The narrower modular belt conveyor runs in the opposite direction to reduce the back pressure of the accumulating products and return them. The wider modular belt conveyor runs in the line direction and serves as an additional storage area. Side guides with free-running rolls minimise friction.

Accumulating pallet circulation for ultra-compact layouts

SPU 2040 carousel with automatic return of empty pallets (workpiece carriers) below: The accumulating single-strand carousel based on the SPU 2040 is suitable for feeding and removing processing cells, for interlinking machines or as a compact assembly line. The pallets are fed in at the top and are ready for loading at the start of the belt. After workpiece removal, empty workpiece carriers are automatically taken along in the deflector and returned to the starting position below the transport level. This means that empty pallets do not have to be handled manually or returned separately. Additional return sections, further conveyor levels or lifting and lowering devices are not required. The system can accumulate, stop and separate workpiece carriers and thus compensate for different processing times, for example.

Platzsparende Förderkombination aus Gurtförderer und Drehtisch mit Abtropfwanne

Compact buffer solution with integrated lubricant return

Space-saving conveyor combination of belt conveyor and rotary table with drip tray: The GUF-P 2000 belt conveyor is connected directly to the upstream machine and transfers parts that are heavily contaminated with lubricant to the DT-P 2040 rotary table via a chute. The table serves as a buffer station from which the parts are removed manually. The table's disc plate is made of perforated sheet metal, through which the excess oil reaches a plastic funnel underneath and can thus be fed directly back into the lubricant circuit. The conveyor is also equipped with a drip tray. An additional drip tray in the lower area of the frame prevents the floor from being soiled by leaking oil. The entire base frame is also mobile to ensure easy access to the lathe for maintenance work.

Production buffer for autonomous feeding of a processing cell

Container snap system based on belt conveyor, including lift for infeed and outfeed: This container snap system with lift unit is suitable for infeed and outfeed of processing cells. Boxes or trays can be loaded either on the upper or lower level. They are then fed to the processing step, transported by lift to the other level and discharged there. The system can accumulate, stop and separate containers. Robotic processing is also possible at the station for containers with integrated workpiece holders. The system can also act as a buffer: A worker loads the feeder and automatically keeps the machine in production for a defined period of time. While the machine is working, the worker can carry out other tasks in parallel.

  • Scope of delivery:
    • 2 GUF-P 2000 AF belt conveyors
    • 1 KHL-2010 short-stroke lift
    • 1 energy chain system for cable routing to the lifting system

Versaflex-WT-System zur Verkettung von zwei manuellen Arbeitsplätzen und Roboterstation

Pallet system for loading, processing and removal

Versaflex pallet system for linking two manual workstations and a robot station: This compact circulation system based on Versaflex is used to feed workpiece carriers to a robot station in a protected area. The workpiece carriers are accumulated and separated on a straight line. In the curve, a worker loads the workpiece carriers at the manual workstation. The pallets (workpiece carriers )are then stowed and separated again on the opposite straight line and fed to the robot station. There they are stopped and centred. The workpiece is removed and processed. The empty workpiece carrier is reloaded with a processed workpiece at the next centring station and transported to a second worker for removal. The empty workpiece carrier is then returned to the first worker for reloading.

  • Scope of delivery:
    • 1 Versaflex A08 slat-band conveyor
    • 10 pallets A08
    • 5 stoppers
    • 2 fixing station

Realise supply and discharge autonomously and simultaneously

SPU 2040 as a double line with return of empty workpiece carriers below: The SPU 2040-based accumulating double line system is suitable for feeding and discharging processing cells, for interlinking machines or as an assembly line. Depending on the task, both lines run in parallel to transport large or heavy products. Alternatively, they run in opposite directions to realise simultaneous infeed and outfeed. The workpiece carriers are fed on the upper transport level. After removal, empty workpiece carriers are automatically taken along in the deflector and returned to the starting position below the transport level. This means that empty workpiece carriers do not have to be handled manually. The double line enables buffering and decoupling with two lines and compensates for cycle differences even with parallel or counter-rotating material feed.

  • Scope of delivery:
    • 1 SPU 2040 slat-band conveyor
    • 10 workpiece carriers
    • 3 Separating unit
    • 1 centring unit
    • Stand system
  • Dimensions LxWxH: 3725x870x1060 mm
  • Workpiece carrier: 235x160 mm
