Vacuum Layer Gripping Systems SPZ

High-performance palletizers for warehousing and intralogistics

Together with capable palletizing robots and gantries, vacuum layer gripping systems from Schmalz increase the production output in the automated handling of products in various industries. Individually planned systems guarantee an optimal process integration and ensure a quick return on investment.

We would be happy to help you design your gripper system. From the project planning and design stages all the way through to the day your product starts operation - we will be with you all the way.

Product Inquiry

Application

  • Palletizing and de-palletizing of layers of various goods
  • Use in warehouse logistics and intralogistics
  • Handling of layers with gaps, mixed layers, intermediate layers, pallets, cardboard packaging and film packaging
  • Palletizing and de-palletizing partial pallets by the combination of vacuum technology and mechanical gripping support

Your Benefits

  • Secure and damage-free gripping of various layer sizes and layer patterns
  • Higher throughput due to process acceleration
  • No gripper changeover and set-up times when performing job changes
  • Innovative gripping concept with mechanical support and global vacuum for additional holding forces
  • Use in the freezer industry sector in areas down to -30°C (optional)
  • Skilled system design according to individual requirements

Design

(1) Flange connection STARR Rigid connection to common robots and gantries

(2) Flange connection FLEX Spring-mounted connection to common robots and gantries

(3) Various gripper modules

(A) With intermediate layer handling

(B) With global vacuum chamber

(C) With layer detection

(D) With mechanical clamping

(4) Suction box with foam For virtually all workpieces, optionally with zoning

(5) Suction box with suction cups For uneven workpieces, optionally with zoning

(6) Suction box with skirt For difficult workpieces, with global vacuum chamber

Basic Configurations

The layer gripping system SPZ is available in three basic configurations, differing in their gripping technology.

SPZ with vacuum suction area

  • Sealing foam for homogenous and intrinsically stable product layers, such as jars and cans
  • Suction cups for flexible workpieces

SPZ-M with mechanical gripping support

  • Additional stabilization of instable and porous product layers, such as cardboard boxes and beverage trays

SPZ-M-C with global vacuum

  • Maximum holding force for product layers that cannot be applied from the top (e.g. mixed layers and layers with gaps)

SPZ-S with blocking module

  • Modular system for blocking large-area grippers (FMP, FMP-S, FXP, FXP-S)
  • Layerwise handling of cardboard boxes for palletizing and depalletizing
  • Handling in rows and individual picking up and taking off of cardboard boxes

Industry-Specific Versions

Schmalz has developed specific layer gripping systems for typical applications of particular industries.

SPZ Glass

  • Palletizing and depalletizing of jars and cans

SPZ Packaging

  • Palletizing and depalletizing of cardboard boxes, beverage trays etc.

SPZ Logistics

  • Handling of various product layers in warehousing and intralogistics

SPZ Nesting

  • De-stacking of cut optimized wooden or metal sheets in a single handling process

Innovative Expansion Options

In order to optimize cycle times, energy consumption and process safety, the layer gripping system can be equipped with various additional features and thus be adapted to process-specific requirements.

Sensor Unit
Optimization of cycle times and increased process safety due to vacuum detection and parts control

Energy Saving Version
Reduced energy consumption due to workpiece and process-dependent blower regulation (by frequency converter)

Collision Detection
Avoidance of damages on the workpieces and system standstills due to floating attachment with collision monitoring

Intermediate Layer Separation
Process-safe separation of various intermediate layers

Deep-Freezing Version
Suitable for use at temperatures down to -30 °C (or -22 °F)

Mechanical Pallet Gripping Arms
Safe handling of one or more palettes, servomotordriven

* The energy savings are dependent on many factors (cycle, handling process, safety factor, porosity of workpiece, etc.) and must always be determined individually

Technical Data

Every layer gripping system can be adapted to individual requirements. The following data are therefore reference values and may vary depending on the application. Suction tests with original workpieces are always required to ensure functionality. They are executed in our test center.
