Abstract
An adhesive dispensing system includes a pump and at least one sensor positioned to sense movements of a component of the pump and produce signals based on the sensed movements. The dispensing system also includes a controller communicating with the at least one sensor to collect information regarding operational cycles of the pump based on the signals. As a result, one or more diagnostic processes are enabled at the controller during operation of the adhesive dispensing system. These diagnostic processes may include a leak rate test for the dispensing system, an overspeed detection test for the pump, and expected life cycle monitoring of the pump or other components.
Claims13
An adhesive dispensing system, comprising:
- a pump including a pump component that moves to move a liquid adhesive;
- a first section comprising a first housing adapted to receive at least part of the pump component, wherein the first section is configured to operate the pump component;
- and
- a second section comprising at least one sensor, a diagnostic device and a second housing adapted to receive at least part of the pump component, and
- wherein the at least one sensor is positioned to sense movements of the pump component and produce signals based on the sensed movements,
- wherein the diagnostic device includes a controller communicating with the at least one sensor to collect information regarding operational cycles of the pump based on the signals, the controller of the diagnostic device being configured to perform at least one diagnostic process based on the collected information, and
- wherein the first housing is coupled to the second housing such that the pump component extends from the first housing into the second housing.
