Layer Gripping Systems

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.


Layer-wise palletizing and depalletizing of a wide variety of goods
Application in warehousing and intralogistics
Handling of layers with gaps, mixed layers, intermediate layers, pallets, cardboard and film packaging
Loading and unloading of partially loaded pallets by combining vacuum technology with mechanical gripping support
Safe and damage-free handling of different layer sizes and patterns without retooling when changing products
Higher throughput due to process acceleration
Innovative gripping concept with mechanical support and global vacuum for additional holding force
Expert system design according to individual requirements
Use in deep-freeze area down to -30° C possible (optional)

(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

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.

***Type SPZ-M-C can be optionally equipped without suction area. Handling of the workpieces is then performed by the mechanical gripping and the global vacuum

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

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
