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.
