The self-closing valves were studied specifically to function with exceptional reliability in the stoneworking environment where water, dirt, and processing residues can impair not merely equipment life expectancy but above all its reliability.
Numerically controlled stone slabs handling robot
Handling robot for loading, unloading, traversing, and flipping products in sheet form. The very low cycle time and smoothness of movements are factors that make the robot suitable for highly automated plants that also process fragile and precious materials.
- Siemens numerical control and digital brushless motor drives1
Siemens numerical control and digital brushless motor drives
The numerical control makes it possible to execute movements, interpolating the axes in order to work faster and achieve short cycle times, and to handle products without abrupt changes in speed and direction with the associated risks of load loss. The choice of a Siemens numerical control is specifically aimed at guaranteeing absolute reliability.
- Ample suction cups with shock cushioning system and self-closing valves2
Ample suction cups with shock cushioning system and self-closing valves
A large number of suction cups, installed on several carrier arms, makes it possible to cover the surface of even the biggest slabs. Each suction cup has a dedicated shock absorber with movements assisted by recirculating ball sleeves to ensure the required high sensitivity, especially in slab approach and release phases. The special self-closing valves means vacuum force is automatically concentrated exclusively on the suction cups effectively gripping the slab, without requiring operator intervention or preselection of areas.
- Single column configuration for easy access and integration with shuttles and AGVs3
Single column configuration for easy access and integration with shuttles and AGVs
Although it can be configured in a gantry version, the single column style is the most practical and popular because it assures a versatile interface with other tending equipment. Absence of tracks at the front of the machine makes the area safer when the operator is interacting with the JOT robot. In addition, this configuration makes the system easily integrable with modern AGVs, which can enter and exit the work area freely without requiring a turntable.
- Easy to configure parametric software4
Easy to configure parametric software
Recently redesigned and updated, the Jot robot embodies a new software concept. The robot was designed so that it could be used, reprogrammed and configured also without the aid of specialised technicians, except for the most complex operations. The codification system features block type architecture with self-learning capabilities for direction change points. Machine status information readily visible on a handy synoptic screen.
- High efficiency mechanical elements articulated on recirculating ball guides5
High efficiency mechanical elements articulated on recirculating ball guides
Vertical movements of the rotating unit slide are assured by preloaded recirculating ball guides shielded by bellows. This type of component eliminates the need for backlash recovery adjustments while constantly ensuring the absence of arm pitching deflection, either with or without a load. The arm rotation movement is supported by a geared slewing ring with large diameter bearing balls.
Book match and block recomposition operating modes
Jot was created to manage work processes on natural stone with management of both book match, meaning loading/unloading of slabs placed alternately with the exposed face upward and downward, and by block recomposition, meaning when working with semi-finished slabs that must be placed precisely in their original position at the end of the production process. This system is possible thanks to the accessories of the rake roller conveyors and turntables mounted beneath them.
- / 01Self-closing valves impervious to contamination
Each Jot robot can be different, depending on the use, the material to be handled, and special contingencies that may arise. A vast range of configurations and accessories make the system adaptable to match all situations. Rotary arm, special vacuum pumps for porous materials, clamping/supporting grippers, extended guide ways, more powerful drive units, and gantry versions are just some of the possibilities./ 02Vast range of configurations and accessories
There are various types of special suction cups available, some of which particularly suitable for gripping and handling difficult materials (with high surface roughness), and very porous materials./ 03Special suction cups for rough or porous materials
