PACKAGE STRAPPER |
摘要 |
A package strapper with three motor-driven mechanisms, specifically a strap feed, a strap stretcher, and a strap-end fastener. The mechanisms are mounted on a strap track that loops around the package. The strap feed includes at least two wheels, each forced against one side of the strap by a spring. The motor that drives the strap feed can be reversed. The strap-stretcher wheel is between the feed and the track and is partly loosely surrounded by a strap guide. One end of the guide opens into the track. The strap-feed motor and the strap-stretcher motor are asynchronous threephase motors. They are connected to a frequency converter that supplies them with electricity of varying frequency and potential and controlled by controls or by a processor integrated into the frequency converter. A manually adjustable terminal strap-tension selector is connected to the controls or to the processor. The frequency of the electricity that powers the strap-stretcher motor is varied in accordance with the prescribed terminal tension. The electricity that powers the strap-feed motor is varied in accordance with frequency and phase.
