Model SD Servo Drive Depositors

Riggs Autopack is able to provide servo drive depositors which constitutes our Model SD range. We can provide full servo control or back-stop only for all our single or multi-head depositors and filling machines.

Advantages Of Servo Over Pneumatics

Pre-set recipe control via HMI to automatically set speed and weight.
Greater control on fine increment adjustment to weight and speed during operation.
Complete control over stroke action to maximise throughputs per product.
Running cost savings due to reduced pneumatic requirements.
Data extraction via USB for performance and downtime.
Automatic feedback adjustment to weights from a check weigh (*bear in mind there may be some distance between the check weigh and the depositor – not instant feedback and not pump specific alterations).

Automatic Synchronisation Of Stroke Setting

Instant synchronisation of the dispensing units on "multi-pump" machines using pre-set recipe selection rather than having to use restriction valves on pneumatic pumps. This dramatically reduces valuable set-up time. Total flexibility of deposit and priming speeds during stroke: ramp up / ramp down functions are available to maximise speeds for narrow neck containers, splashing products or where there's a risk of contaminating the seal areas. This allows filling speeds to be maximised which can increase throughputs. Riggs Autopack Video: Youtube


Alternate strokes from multi-pump applications can improve throughputs on specific applications. E.g. for applications such as platen formations and deposit weights above barrel capacity. Two strokes can be achieved without priming which will then be carried out during a third operation of a line such as indexing, capping, sealing or manual handling. Riggs Autopack Video: Youtube


A number of forward strokes from one prime. This is useful on platen heat sealing conveyors, sequencing heads or even VFFS applications. One pump can sequence a number of deposits (individual weight against barrel volume specific) eradicating priming during operation until a third process such as index, container traverse, seal or capping is required.

On a two pump system, the first pump could deposit ‘X’ amount of shots, at the end of the stroke, the second pump would start the same sequence of ‘X’ shots whilst the first pump primes. Allowing for continuous depositing. Riggs Autopack Video: Youtube


We can time in two different stroke lengths to start and finish at the same time allowing consistent dual product depositing. This function opens up the ability to be more creative with the visual end result of a product, giving consistent repeatability over a number of different axis. Riggs Autopack Video: Youtube
