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 collection of consecutive product steps autonomously. The Austrian machine producer mentioned its LTM-CI is optimized for small components meeting.
Compact automation will be important for finish customers that need to automate however don’t have the area 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 widely known furnishings retailer that wants thousands and thousands of those components yearly,” mentioned Roland Schiermayr, head of the Automation Analysis and Growth Division at STIWA.
“The corporate needed to purchase a brand new manufacturing machine,” he mentioned. “The prevailing machine was 10 m [32.8 ft.] lengthy – for the manufacturing of small elements 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 totally make the most of all miniaturization potentialities.”
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 appropriately positions these components on a conveyor belt so it’s prepared for the following manufacturing step.
Subsequent, the system transports the elements to the respective stations. There, delicate grippers decide 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 sleek transport of conveyor belts with the speedy 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 rely upon the wants and specs of the client.
“We will combine as much as 22 operate modules, every measuring 90 mm [3.5 in.] in width, for various work steps,” mentioned Christian Mersnik, who was concerned in improvement from Day 1. “These capabilities embody, for instance, decide 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 mentioned that its compact automation system has been properly acquired by prospects. Its prospects respect the uniform, clean actions of the system. In addition they say that these actions don’t include impacts or vibrations, which ensures a secure course of.

The corporate mentioned the LTM-CI can scale 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 significant contribution to the sleek 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 items and grippers. STIWA claimed that one explicit 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 pressure 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 items that transfer the instruments or elements to a particular place.
“At this level within the system, we require an especially excessive stage of precision and repeatability,” Mersnik mentioned. “That is why it was an vital argument for us that FAULHABER was capable of ship this motor with an identical multiturn absolute encoder. The alerts from this encoder are obligatory to attain 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 companion.
“We topic our personal components in addition to moreover bought elements to endurance exams,” Schiermayr mentioned. “In these exams, we try to destroy the components by way of put on and unfavorable situations. Solely these components that survive the endurance exams 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 attain our personal peak values with minimal area necessities and the shortest cycle occasions.”
