Depalletizers for empty glass bottles

Handling empty containers at the beginning of production is one of the most critical elements in a company.

With regard to empty bottle depalletizers, most companies need machines that maximize the production space, facilitate correct management of the empty containers and make the most of the time taken to load, unload and handle the containers.

Taking these factors into account, Traktech offers a range of depalletizing systems ranging from semi-automatic models to high-speed models operated and controlled simply by a push button.

This equipment is designed to speed up the production and packaging process, which can also be integrated into the beginning of an existing production line, with the aim of saving space and increasing flexibility and efficiency.

Applications of bottle depalletizers

The main application of a depalletizer is to extract the empty glass, plastic or metal containers from the pallet, to place them on a conveyor on the packaging line.

Our depalletizers are designed to use pallets measuring 1000 x 1200 mm, with a maximum pallet height of 2500 mm (pallet included).

There is no limit for different sizes of bottles or different numbers of layers, neither do they require the intervention of a worker to change the format, as each format has its parameters entered on the screen.

Depalletizers can work with flat trays or trays with the covers facing downwards, except the DVI model, which can only work with trays with the covers facing upwards.

Sectors that this solution can cater for:

  • Food.
  • Drinks.
  • Chemical.
  • Pharmaceutical.
  • Cosmetics.

Technical characteristics of the depalletizers

The depalletizing station consists of an elevator, where the platform is raised to the unloading height. The position of the elevator and its starting/stopping is controlled by an encoder system where each format has its own parameters.

The depalletizer has a rigid stainless-steel structure, made of tubes, folded sheet metal and sections, adequate to receive and support different types of equipment.

The containers are transferred to the exit conveyor or the reception hopper, by means of a line to line pusher system or a suction system, depending on the type of bottle.

When one layer is finished, the separator is automatically removed, by a pick and place, and put in the storage area.

In cases where the pallet is “tall” (up to 2500 mm), the exit conveyor is equipped with a “Side Grip” conveyor at the end to move the bottles to the normal working height of the filling lines (1000 mm).

Maximum production: 18,000 BPH.

 

Types of depalletizers

According to the material, the geometry of the container and speed, Traktech offers different types of depalletizers:

  1. DVI depalletizer, by suction and inliner: A suction head lifts the while layer of containers and moves them to the output aligner.
  2. DPI depalletizer, by pushing and inliner: The containers are pushed to the simple conveyor or exit aligner.
  3. DPB depalletizer, by bulk pushing: The containers are pushed to a large capacity hopper that feeds a bottle positioner.

All our depalletizers can be automated with elements such as:

  • Full pallets in waiting.
  • Empty pallet grouper.
  • Automatic layer removal and storage.
  • Cleaning of containers during the descent to the line.

The Depalletizer in a production line

As an example, below you can see an illustration showing the start of a production line, which includes three pieces of equipment: A DPB depalletizer for plastic bottles, which feeds a Rotrak Positioner for positioning of the bottles and ends with a Rinser SG-20 that delivers clean bottles to the filler, for filling and capping.
