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 elements meeting.
Compact automation might be important for finish customers that wish to automate however don’t have the house for a big system. As well as, these compact programs 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 elements 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 prevailing 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 slim Alpine valley. This was the impetus for us to totally make the most of all miniaturization prospects.”
For its compact automation programs, the corporate 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 elements from storage containers and separates them utilizing a shaker. It then appropriately positions these elements 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 decide them up and be a 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 shopper.
“We will 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 growth from Day 1. “These features embrace, 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 stated that its compact automation system has been properly obtained by clients. Its clients admire the uniform, clean actions of the system. In addition they say that these actions don’t include impacts or vibrations, which ensures a steady 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 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 job at as much as 20 factors within the system, together with stopper items 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.) large 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 degree of precision and repeatability,” Mersnik stated. “Because of this it was an necessary argument for us that FAULHABER was capable of ship this motor with an identical multiturn absolute encoder. The alerts from this encoder are essential to attain the excessive manufacturing high quality and for high quality assurance.”
STIWA ensures its compact automation clients fault-free operation of at least 60 million strokes. This quantity must be achieved by all of the transferring elements inside the system, which is one more reason why the corporate picked FAULHABER as its companion.
“We topic our personal elements in addition to moreover bought elements to endurance checks,” Schiermayr stated. “In these checks, we try and destroy the elements by means of put on and unfavorable situations. Solely these elements that survive the endurance checks 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 attain our personal peak values with minimal house necessities and the shortest cycle occasions.”
