Chain Packaging


The precise manual packaging of a pre-set length of chain can be a tedious and labor intensive procedure. Technical Systems thus designed and developed an automated chain packaging machine prototype which HmT Mechatronics was in charge of automating.

This machine automatically pulls the chain from a bobbin and clamps it with an electromagnet. A reflective laser sensor is used to detect the clamping position and also for quality control data while a rotary encoder is used to measure the amount of chain. Pneumatic cylinders are then used to transfer the chain to the mandrill which contains a permanent magnet. This mandrill motor is used to wind the batches of chain into rolls. Once at the preset length, a pneumatic punch breaks the chain after it was held at an exact angle by another cylinder and the clamp. All the interaction, control and data feedback of this machine is done via the HMI.

Wafer Packer


HmTmechatronics was contracted by Neptek to implement a control system on a automated packer. Product was coming out of a machine at a level that was uncomfortable and unhealthy to work at. This lead to the need for a packaging machine that would automatically pack the product in bags and at a level that is safe to work at.

With the help of linear actuators, product was moved from one conveyor on to a platform. The platform lifted product to the desired height, from there it was moved on to a second conveyor. The conveyor then fed the product into bags. A first for HmT : One of the requirements was that the system had to have a safety controller. This protected any user from working on the machine while it is in operation. While nothing new to industry these controllers aren’t widely used and after seeing what these can bring to the table in terms of safety, we can definitely recommend that these be implemented in factories.
