Ceiling Conveyors for Plant Chaining

MTF Technik - Ceiling Conveyors for Plant Chaining

Task: Interlinking of production, assembly and packaging

  • In a large clean room (ISO class 8), various phamaceutical plastic parts are being produced, assembled and packed. The size of the production hall is 140 x 35m

  • The machines are located at different places in the entire hall

  • The parts have to be conveyed batchwise and independently and are conveyed to different assembly and packaging machines

  • The whole conveying technique has to be places on ceiling suspensions

  • The outline has to consider existing interfering edges caused by machines, media supply, lighting bands, ventilation outlets, building edges, conveying technique etc.

  • MTF Technik has the entire responsibility for projecting, installation, control engineering and setting-up operation

  • The project has to be implemented in several steps from 2006 on to 2011/12

  • The installation can only be done on certain days (on Sundays or in the two weeks of annual closing)

  • The conveying technique has to be divided into sections of a length of max. 4 metres, in order to be carried by elevators into the production area. The mounting of the sections has to be done on site

  • The facility has to be available as much as possible. The facility is in fullt-time operation on 280 days per year

Solution: Large controlled ceiling conveyor system with distributors

  • Conveying system consisting of a total of about 150 conveyors with a total conveying line of approx. 700m - beginning with machine discharge conveyor, small hopper conveyors large Z-conveyors with 75° angles, distribution switches to tubular systems

  • The illustration only shows a detail of the full system. The conveying lines coloured red, yellow and green mark project part that was realised in one step

  • The whole hall was equipped with approx. 250 MTF devices (conveyors, separating drums, buffering devices, etc.)

  • Peripheral control system with several Siemens S7 controls (one switchboard per product) and triggering of the drives by means of bus systems

  • Peripheric control panels incl. several 7-segment displays and signal lamps for control of the system status

  • Special control with interface to a plant data collection system

  • Interfaces to existing production machines (material requsitions, approval notices, etc.)

  • Remote maintenance modules in the control systems in order to change the program quickly and easily

  • Material spillovers at the end of each line with weighing systems resp. quantity determination

  • Reversing conveyors and tubular switches for dividing the conveying stream to different discharge points

  • FDA-approved belts, discharge covers made of anodised aluminum or stainless steel

  • Mostly rolling carrying run to prevent abrasion and to lower the required power

  • Multi-Tech Conveyors wiith single lengths up to 45m and widths between 00 und 400mm, depending on the product. The conveying sections are 4 m long and can be mounted by bolted connections on site. The belts dispose of removable endless joints

  • Complex sensor system at the conveyors for permanent control of the system status

  • Complete documentation of the system incl. allocation of the conveyor technique to the single production machines

  • Maintenance agreement with the customer (in preparation)
