Fast format changes thanks to customised tool solutions

Fast format changes and the cost-effective integration of new formats into the packaging process are in demand today. Schubert already had a clear idea of the perfect format part decades ago and offers exchangeable or adjustable moulds.

Manufacturers who serve many product formats or work for fast-moving industries need highly flexible packaging machines. Fast format changes and the ability to integrate new formats into the packaging process at low cost are essential. However, every company defines its requirements differently.

The concept of modular TLM machine Schubert consistently pursues this goal right through to its customised robotic tools. Decades ago Gerhard Schubert had a clear idea of the perfect format partThe more precisely a mould is tailored to the product, the better the product handling. The faster the format change, the more efficient the production.

Sealing tool for cartons
Format changes can be carried out even faster thanks to additional changeover levels in the moulds. Here is an appropriate sealing mould for cartons.

Whether interchangeable or adjustable robot tools the machine manufacturer offers both and designs a customised customer solution using its modular technologies. If the experts are involved in a project at an early stage, they work with the customer to revise the desired packaging. This is because if the packaging dimensions are standardised, e.g. by restricting a dimension to just one length, this has a direct impact on the number and production of the format parts. This allows the packaging process to be simplified and costs to be saved through foresighted planning.

Flexible format change for high process reliability

Schubert machines are equipped as standard with per format via a coded tool set, which is immediately ready for use without adjustment. Those who prefer high process reliability and a quick format change are well served by interchangeable format sets. The complete mould is always changed in order to be able to pack a different format with the machine.

Carton sealer with manual adjustment
Adjustable tools such as this carton closing tool with manual adjustment are often worthwhile from just three formats.

However, if you want to save on storage space, it is better to use adjustable tools that can be adapted to other formats manually or with the help of motors. The prerequisite for this is sufficient space in the machine for the adjustable format parts. In order to offer customers the greatest possible flexibility, Schubert has designed the The adjustable tools are also designed to be completely interchangeable. This is because formats that are slightly outside the intended scheme can then also be processed.

Adjustable tools as a future-proof investment

The adjustable moulds can be worthwhile from just three formats, as the storage of interchangeable moulds requires a lot of space. This makes it relatively easy to adjust the moulds from the outside if there is sufficient space available in the machines. A technology of the future that Schubert is also the integration of motors into the F2 mould. The microdrives enable finely controlled movements and precise adjustment of the moulds directly on site. Such adjustable units are a safe investment in the future, as they enable a high degree of flexibility and reduce the follow-up costs for additional formats.

3D format parts such as those on this gripper mould are quick and easy to change. The part streaming platform from Schubert Additive Solutions allows customers to print such parts themselves with certified print jobs and use them immediately

Interfaces for additional Alternating levels

Both the adjustable and interchangeable robot moulds offer even more flexibility thanks to additional interchangeable levels. Schubert has therefore One or even two additional interfaces integrated for changing, closer to the product. This offers customers numerous advantages:

  • Instead of a large mould, small units can be exchanged.
  • If complete changing units that are pre-equipped with changing tools are exchanged, a format change can be carried out in just a few minutes.
  • New formats can be realised cost-effectively and with short delivery times thanks to the small tool units.
  • Small tools require less material and less storage space for the tool sets.
