An Interview with Jan Kohlmeyer, Design Engineer for Cartoning

Expertise Series

Bosch Engineer Interview Cartoner Series. Read the whole interview below.

Germany is renowned globally for well engineered and quality products. What influenced you to become an engineer?
As a Bosch fitter installing GKF capsule fillers and KKE capsule checkweighers, one day I was no longer satisfied with this challenge and decided to become a technician-engineer. I felt I could do design work at a high level and correct issues I had witnessed as a fitter.

Jan Kohlmeyer

Why did you choose to work for BOSCH?
At 18 I took aptitude tests for Daimler, Bosch, and a few other companies. I was interested in being an electronic technician but I tested highest in mechanics. After a tour of the Bosch facility I found it very interesting. I’m happy about my choice to be in cartoning because of the vast challenges working with so many different feeding and packaging solutions.


What machines have you worked with in your current position?
The CUC prototype was the first machine I worked on as a design engineer. I’m also active with the CTC. The CarT5 has been going through a resurgence and has been a very popular machine with our customers. Since the design was from some time ago, Bosch needed someone to bring the machine up to current standards, entering all the drawings in CAD, and fitting it with a modern control system.


Bosch manufactures both mechanical and servo-controlled versions of the side load cartoner. What is the advantage of each solution?
Servo-driven units are more flexible. The machine can be more modular. The speeds and movements can be more finitely controlled. Servos require less power to operate.Mechanical units have an advantage with price if the function of the machine does not require final movement adjustment.

It is really all about finding the appropriate solution for the customer’s requirements. After a short conversation or a review of the URS this can easily be determined.


What challenges do you face designing a robust, quality machine for a price competitive market?
In the last few years we in engineering have been tasked to do some re-engineering in order to reduce the sale price of our units, while still maintaining the required Bosch standard and quality levels. This has been challenging but very rewarding. Sales have increased because of this effort.


Lowest lifetime cost of ownership is important for businesses. How does Bosch help meet this requirement with design?
Design is based on feedback from the market. If a customer has a repeat problem or reoccurring maintenance issue we work together with them to determine the cause. We correct this and implement a design change in the future. Sometimes a design will be more expensive in order to be robust.Machines are built in series, multiple units at a time. This reduces the cost of the machine but increases the cost of corrected stock units if a new “fix” is required on the design. There must be an economical balance. We know this will help both our customers and save us time and money in the future.
