STIWA is an skilled developer of compact mechatronic programs that may carry out a collection 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 need to automate however don’t have the house for a big system. As well as, these compact programs can excel at dealing with small parts. 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 thousands and thousands of those components yearly,” stated Roland Schiermayr, head of the Automation Analysis and Growth Division at STIWA.
“The corporate needed to purchase a brand new manufacturing machine,” he stated. “The present machine was 10 m [32.8 ft.] lengthy – for the manufacturing of small parts measuring only a few 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 programs, the company makes use of linear and rotating micromotors from FAULHABER to carry out key duties.

Contained in the LTM-CI
Computerized actions throughout the LTM-CI occur so rapidly 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 appropriately positions these components on a conveyor belt so it’s prepared for the subsequent manufacturing step.
Subsequent, the system transports the parts to the respective stations. There, delicate grippers choose them up and be part of them collectively, or course of them another way. STIWA compares the actions of the system to a dance, combining the graceful transport of conveyor belts with the fast actions of grippers.
This whole system, relying on the configuration and tools 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 parts rely on the wants and specs of the client.
“We are able to combine as much as 22 operate 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 nicely acquired by prospects. Its prospects recognize the uniform, clean 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 cut back cycle occasions 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 serious 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 job 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.) vast and 19.1 mm (0.7 in.) excessive, the drive can produce a steady power of three.6 Newtons.
The system additionally makes use of FAULHABER’s brushless BX4 2250 collection of motors. Within the portal dealing with of the compact automation, this motor drives the swivel models that transfer the instruments or parts to a particular place.
“At this level within the system, we require a particularly excessive degree of precision and repeatability,” Mersnik stated. “This is the reason it was an vital argument for us that FAULHABER was capable of ship this motor with an identical multiturn absolute encoder. The indicators from this encoder are essential to realize the excessive manufacturing high quality and for high quality assurance.”
STIWA ensures its compact automation prospects fault-free operation of a minimum of 60 million strokes. This quantity needs to be achieved by all of the transferring components throughout the system, which is another excuse why the corporate picked FAULHABER as its accomplice.
“We topic our personal components in addition to moreover bought parts to endurance assessments,” Schiermayr stated. “In these assessments, we try to destroy the components via put on and unfavorable circumstances. Solely these components that survive the endurance assessments are put in within the machines.”
“The motors from FAULHABER have proven that they’ll meet such excessive necessities,” he added. “They assist us to realize our personal peak values with minimal house necessities and the shortest cycle occasions.”
