Prototype XHE Electronic Handle Applicator machine for the horizontal application of handles on cardboard boxes
Requests to apply the handle at low production speeds rarely occur, even if they present the same design difficulties as those at high speed.
However, the request is characterized by quite demanding constraints:
- application of the handle respecting certain measurements and position with small error tolerance and high repeatability
- in case of an application error the machine must not dent or break the box
- horizontal application
- precise and repeatable positioning of the black mark on the handle
- excellent adhesion along the entire useful length of the adhesive tape with the cardboard box such as to guarantee a secure hold, preventing the handle from coming off during transport.
A perfect handle for a special product.
The Prototype
After several meetings with our team of engineers and technicians, the work was taken over, resulting in the solution shown in the following video.
Description of the prototype XHE Handle Applicator Machine
We sought a solution that was simple to use and at the same time effective.
The machine is fed by accessing one box at a time, via a measuring belt, in order to avoid accumulations with varied thrusts due to the different weight of each box (the boxes can have a variable internal content.
The box is delivered to a transfer belt which delivers it individually to the handling belt.
Considering the low speeds, we opted for an intermittent advancement and an application of the handle with the box still to favor maximum adhesion of the adhesive tape glue on the cardboard box.
A meticulous and detailed check of the position of the box before the pliers come into action to apply the handle.
The movement of the gripper is entrusted to a servomotor rather than a pneumatic cylinder, this to have a controlled speed during the most important phase, that of adhesion of the glue of the adhesive tape on the cardboard of the box.
The control system is a Siemens PLC from the S7-1200 series with related expansions and a 7" HMI display also from the same manufacturer.
As in all our machines, the remote connection module is present to be able to provide assistance even remotely.
The excellent Omron Q2V series inverters, communication via Modbus, for the control of conveyor belts. Easy access for removing the box if necessary.
