Our hydraulic drainage presses dispose of old labels in bottling facilities efficiently and economically. The WEIMA A.300 produces pressed labels with an output diameter of 300 mm. Discharged labels are first picked up by the label press, then pressed and finally transported drip-free into a container. A hydraulic cylinder reduces the volume of the unpressed labels by approx. 70%, the residual moisture is then approx. 30%. The pressed out lye is collected and can be returned to the cleaning machine.
The label press can be installed directly at your bottle washing machine. The already existing label discharge conveyor easily guides the labels into the press. This machine can be operated fully automatically. The cleaning and maintenance is particularly user-friendly. WEIMA presses are resistant to contaminants.
Machines of the A series have a particularly robust design. The design is comparatively simple and gets by with few electronics. In contrast to screw presses, only a few moving parts are installed. Thus, even with many years of use, wear is minimal.
WEIMA machines of the A series are made of stainless steel. This makes the presses particularly durable, low-maintenance and hygienic.
The discs are formed by the press cylinder, which presses the material against the previously produced discs, which are still in the discharge pipe. The angled bend of the discharge pipe generates enough counterpressure to strongly compact and drain the material. In addition, the wedge position of the discharge pipe can be used to set subsequent recompaction.
WEIMA label presses achieve an increased discharge height due to the inclined discharge pipe. This allows the pressed products to be discharged directly into a tipping trough without using a conveyor belt. Depending on the space requirements, different versions with discharge to the left or right can be configured. The system can thus be seamlessly integrated into your production line.
For optimal integration into your production line, WEIMA label presses can be installed either standing or hanging on the bottle washing machine. The networking of the press with the upstream bottle washing machine ensures the highest throughputs. For example, the cycle times can be switched synchronously. The label presses of the A series can also be used as a stand-alone solution without any problems. You can see how this can look like in the video at the Rothaus Brauerei.
Due to the robust machine design, WEIMA label presses are particularly resistant to contaminants. In contrast to screw presses, presses of the A series cannot block mechanically and simply press dangerous foreign materials such as bails of swing-bottle glass bottles into the pressed product. This way, clogging or jamming of the machine can be avoided.
The built-in PLC control is optimally adapted to the drainage process. Many settings, such as the press force and cycle time, are preset but can be easily adapted to the desired application. If required, the machine can be used in manual or automatic mode. We use only high-quality brand components – for example from Siemens, Allen Bradley or Rittal.
The A series offers various flexible positioning options and can be optimally adapted to your spatial conditions. Due to brakable rollers, standing machines are freely movable and can be easily repositioned for maintenance and cleaning, for example. On request, the hydraulic unit including control panel can be installed up to 7.5 m away from the label press.
The A series is equipped with an aluminum hydraulic tank as standard. This keeps the hydraulic oil at a constant temperature – without the use of active cooling. This also ensures multi-shift operation around the clock.
The caustic pressed out during the pressing process is collected in the lye collection tray. From there, the liquid can be discharged in a targeted manner – into the drain or to the caustic recirculation system. The connection option can be defined individually according to customer requirements.
