The compact LTM-CI from STIWA is optimized for small half meeting. | Supply: FAULHABER

STIWA is an skilled developer of compact mechatronic methods that may carry out a sequence of consecutive product steps autonomously. The Austrian machine producer stated its LTM-CI is optimized for small components meeting. 

Compact automation could be important for finish customers that wish to automate however don’t have the house for a big system. As well as, these compact methods can excel at dealing with small elements. STIWA designed its system for merchandise with a spatial diagonal of as much as 30 mm (1.1 in.). 

“A buyer within the west of Austria produces dampers for a well known furnishings retailer that wants hundreds of thousands of those components yearly,” stated Roland Schiermayr, head of the Automation Analysis and Growth Division at STIWA.

“The corporate wished to purchase a brand new manufacturing machine,” he stated. “The present machine was 10 m [32.8 ft.] lengthy – for the manufacturing of small elements measuring just some centimeters in size, this was merely an excessive amount of for the manufacturing web site in a slender Alpine valley. This was the impetus for us to completely make the most of all miniaturization prospects.”

For its compact automation methods, the firm makes use of linear and rotating micromotors from FAULHABER to carry out key duties.

Contained in the LTM-CI

Computerized actions inside the LTM-CI occur so shortly that the human eye can barely sustain with the person automation steps. First, the system feeds particular person components from storage containers and separates them utilizing a shaker. It then accurately positions these components on a conveyor belt so it’s prepared for the subsequent manufacturing step. 

Subsequent, the system transports the elements to the respective stations. There, delicate grippers choose them up and be part of them collectively, or course of them differently. STIWA compares the actions of the system to a dance, combining the graceful transport of conveyor belts with the fast actions of grippers. 

This complete system, relying on the configuration and gear wanted, is simply 3 to 4 m (9.8 to 13.1 ft.) lengthy. STIWA made the bases of the system from a rigidly linked transport system, and the opposite system elements depend upon the wants and specs of the client. 

“We are able to combine as much as 22 perform modules, every measuring 90 mm [3.5 in.] in width, for various work steps,” stated Christian Mersnik, who was concerned in improvement from Day 1. “These capabilities embrace, for instance, choose and place, laser welding with as much as 5 levels of freedom, screw insertion, press-in operations, labeling, in addition to testing and measuring processes.”

STIWA compact automation will get buyer curiosity

STIWA stated that its compact automation system has been effectively acquired by prospects. Its prospects admire the uniform, easy actions of the system. Additionally they say that these actions don’t include impacts or vibrations, which ensures a secure course of.

The corporate stated the LTM-CI can scale back cycle instances to virtually simply half a second, which brings a big leap in productiveness. STIWA famous that the drives used within the FAULHABER actuators make a significant contribution to the graceful motion of the machine and its excessive velocity. 

The LTM-CI makes use of the LM 1247 linear actuator motor from FAULHABER. This actuator performs its process at as much as 20 factors within the system, together with stopper models and grippers. STIWA claimed that one specific power of the FAULHABER linear motors is its excessive velocity. At simply 12.5 mm (0.4 in.) broad and 19.1 mm (0.7 in.) excessive, the drive can produce a steady drive of three.6 Newtons. 

The system additionally makes use of FAULHABER’s brushless BX4 2250 sequence of motors. Within the portal dealing with of the compact automation, this motor drives the swivel models that transfer the instruments or elements to a selected place. 

“At this level within the system, we require an especially excessive degree of precision and repeatability,” Mersnik stated. “This is the reason it was an vital argument for us that FAULHABER was in a position to ship this motor with an identical multiturn absolute encoder. The alerts from this encoder are crucial to realize the excessive manufacturing high quality and for high quality assurance.”

STIWA ensures its compact automation prospects fault-free operation of at least 60 million strokes. This quantity must be achieved by all of the shifting components inside the system, which is one more reason why the corporate picked FAULHABER as its associate. 

“We topic our personal components in addition to moreover bought elements to endurance checks,” Schiermayr stated. “In these checks, we try and destroy the components via put on and unfavorable situations. Solely these components that survive the endurance checks are put in within the machines.”

“The motors from FAULHABER have proven that they will meet such excessive necessities,” he added. “They assist us to realize our personal peak values with minimal house necessities and the shortest cycle instances.”
