Within a stretch film wrapping system, one particular electric motor generate system (32) is provided for controlling the rotation of any rotational thrive member (30) when it comes to a fixed increase fellow member (28) as well as the height of a stretch film roll carriage assemblage (38) movably installed on a wrapping mast (36) fixedly attached to the rotational growth fellow member. A cable drum assemblage (55) is mounted after a driven shaft (50) and biased from a springtime system (72) to some first placement such that as soon as the increase fellow member is rotated, a cable (68) is injury on the cable television drum construction (55) lifting the stretch film roll carriage set up (38). A solenoid system (76) biases the cable drum assemblage (55) to some secondly position in a way that the stretch film carriage assembly (38) is taken care of at a predetermined elevational level by which stretch film is wrapped in a reinforcing setting. An additional solenoid process (78) biases the cord drum set up (55) into a next situation such that the stretch film carriage assembly (38) is relocated to its lowermost situation for the new wrapping operation period.
A single motor unit drive system, to be used in experience of stretch film wrapping
machine for wrapping strètch film around a load disposed at the wrapping station, comprising:
a fixed increase associate;
a rotational increase construction rotatably installed on stated static growth fellow member to be able to orbit across the wrapping station in the
machine in which the load to become wrapped is disposed;
a stretch film roll carriage assemblage attached after explained rotational increase construction in an attempt to be rotatable around the wrapping station together with mentioned rotational growth assembly, and up and down movable with respect to said rotational increase set up, in a way that stretch film dispensed from stated stretch film roll carriage set up can be covered across the fill disposed with the wrapping station at distinct vertical elevational ranges; and
a single motor generate arrangement operatively linked to explained rotational boom assemblage and to mentioned stretch film roll carriage construction mounted upon mentioned rotational boom assembly for managing both the rotational moves of explained rotational thrive assemblage around the wrapping station, as well as the straight moves of stated stretch film roll carriage construction regarding explained rotational thrive assembly to ensure that stated stretch film roll carriage construction could be disposed at said distinct top to bottom elevational amounts with regards to the stress disposed at the wrapping station.
The single motor unit drive system as established in Declare 1, wherein said solitary motor unit push layout includes:
a motor unit fixedly installed with said stationary boom participant and getting a rotary output shaft;
a driven shaft fixedly linked in a very first stop to said rotational growth set up and operatively linked at the secondly finish to stated rotary output shaft of said electric motor to ensure that rotation of mentioned rotary output shaft of said motor brings about rotation of said rotational thrive assemblage;
