Fischbein Saxon: News, product update

24 March 2011

Fischbein Saxon has introduced special realisations for Saxon sealers. Owing to the adaptability of its products and the efforts of its engineering team in London, these achievements are designed to offer flexibility

3m conveyor with an additional 500mm roller section
This option allows the bag to be well supported during the filling process. The bag can then be pushed onto the conveyor where it is transported through the sealer. This solution provides the possibility to no longer start and stop the conveyors, which results in a higher production rate.

The roller section can be applied to medium and light duty Saxon conveyors.

LED indicators & Windows
LED (Light Emitting Diode)
The LED indicator is an option to indicate when a heater or SSR (Solid State Relay: provides power to the heater when it needs to be heated) has failed.

The advantage for adding the LED indicators is to immediately identify to the operator, visually, that either a heater or SSR (Solid State Relay) has failed. Therefore, when the LED is illuminated, this indicates that either the heater or the SSR has failed and it requires replacement. When the LED is not illuminated then the heater and SSR are operating correctly.

In the eventuality of a heater or SSR failure, the LED on the front of the sealer will be illuminated and identify clearly by its position which heater or SSR has failed. This will reduce maintenance and down time of the sealer.

Currently, without this option, when a failure occurs, the operator will only notice that the time it takes for the PID (Proportional Integral Derivative) to reach its operating temperature has increased or that the seal is failing. To identify the failed component, the maintenance engineer must check each heater and SSR individually with a ‘voltage tester’.

How it works?
The self monitoring system (built into the SSR) provides an alarm output in the event of an electrical circuit failure. This means that immediately a fault detection is visually displayed to the operator (via the LED mounted on the sealer panel).

The SSR is constantly monitoring its internal electrical circuit and line voltage for any changes. When the sealer is in cool down mode or below the PID 50°C alarm set point, all the LEDs will be illuminated as no power is being supplied to the heaters.

The LED indicators can be added to the following sealers of the new generation: SB1000, SB1000+, SB3000, SB4000, SH1000, SH2000, SR1000 and SR2000. There is no need for the SB1000 Medical to have the LED indicator as each heater is controlled by its own PID.

Windows
Visual panels have been added as options to the lid of the SB1000, SB1000+, SB3000 and SB4000 Band sealers so that the operator can visually see the bands are intact and can watch the passage of the bag through the sealer.

The visual panels cannot be added to the SH or SR sealers due to the high temperatures generated from the heaters.

The visual panels can be used in conjunction with the LED indicators or they can be supplied independently.

3. Twin Alarm PID (Proportional Integral Derivative)
Operation:
The PID has two independent outputs, which can be used for different purposes. We have used them in the following methods:

Alarm 1:
When the set sealing temperature of the PID has been reached, then a Volt free signal is given which can be used to start an independent process upstream/downstream of the sealer elsewhere in the packaging line, such as the weigher, the bag placer and/or the palletizer.

This can prevent the accidental insertion of bags into the sealer before the correct sealing temperature has been reached or if a PID drops below its set point, the system can then be stopped until the set temperature is restored. This is applied when an automated process for filling the bags is employed. This PID allows a more automated process, therefore relieving the operator from constantly monitoring the sealer.

Alarm 2:
This is used for the cool down process. This shuts the sealer down when the temperature of the heaters has reached 50°C.

This PID can be introduced into the current range of SH, SB, SR sealers during manufacture. The PID can be retrofitted but there is an additional wiring involved and a competent electrician will be required.

Short Infeed
The Short infeed has been developed for a customer who had no sufficient space to accommodate a standard sealer. As the customer required an old model of the Saxon Hot Air 5 the bottom plates have been reduced in length to the minimum length possible.

If a customer requires a short infeed, then additional guarding will be required as well as additional information so that the correct guarding can be manufactured. This will be on a case-by-case evaluation.

The short infeed can be applied to all 1000, 2000, 3000 and 4000 sealers of the new generation.
