Cup Sealing Machine

Technical Data:

What was needed: A cup sealing machine that automatically puts a lid on plastic cups in fast food restaurants
Requirements: 100% lubrication-free and maintenance-free, durable, heat-resistant, moisture-resistant, light-weight, quiet and vibration-free, food-grade compliant
Products used: drylin® R housing bearings
(FJUMT-01-10), Drylin® Linear Guides (TK-04-12),
dryspin® flanged threaded nuts (DST-JFRM) and spindle as well as iglidur® W300 plain bearings (WFM-0608-04)
Success for the customer: The moving parts of the machine should withstand more than 300,000 cycles. The designers therefore use the housing bearings, linear guides, flanged threaded nuts from the dryspin® series and plain bearings from the iglidur® W300 series. All components are suitable for the food industry because they work without lubrication. In addition, they work almost silently.

Problem

Fast food restaurants are still very popular. In order to make sales processes more effective, automation solutions have also been established here. The Korean manufacturer HNDS developed a cup sealing machine that automatically puts a lid on plastic cups. The moving parts of the machine should withstand more than 300,000 cycles. In addition, they must be able to withstand temperatures of around 100 °C. Considering the conditions in a fast food restaurant, the built-in parts must withstand moisture and oil.

Solution

Various igus® components have proven themselves to solve the corresponding requirements. The built-in thread technology, housing bearings, linear guides and plain bearings were able to assert themselves against ball bushings, conventional linear guides and ball screws that were considered as alternatives. They convinced as lightweight, low-noise and lubrication-free variants that have no problems with food. The igus® solutions are used for the nozzle parts and the cup seal. This reduced noise and vibration.
