The only electric motor drive stretch film roll system of pallet stretch wrapper

a cable tv drum assembly, possessing a first finish of any cord set thereon and a second end of said cable fixedly associated with explained stretch film roll carriage assemblage, movably installed upon mentioned driven shaft between a first position where said cable tv drum set up is fixed upon stated static boom fellow member in a way that, when said rotational boom participant rotates regarding said fixed thrive member and explained cable drum assemblage resolved on said static boom fellow member, stated cord will be injury with mentioned cord drum assemblage in order to increase mentioned stretch film roll of orbital stretch wrapper to explained different top to bottom elevational ranges to ensure that stretch film dispensed from said stretch film roll construction will probably be continually twisted round the weight at stated various straight elevational levels, a second position from which said cable drum set up is repaired on stated rotational thrive member to ensure that when mentioned rotational growth fellow member rotates close to stated stretch wrapping machine, stretch film dispensed from stated stretch film roll carriage construction will probably be continuously twisted round the stress disposed at mentioned stretch wrapping machine in the strengthening setting at a specific one of said diverse elevational amounts, along with a 3rd placement in which said cable tv drum assemblage is readily rotatable with explained powered shaft to be able to make it possible for explained stretch film roll carriage assemblage to become disposed in a lowermost one among explained diverse elevational degrees in preparation for a new stretch film wrapping machineoperations routine.

The stretch film wrapping machine as established in Assert 18, whereby explained solitary engine travel arrangement additional includes:

a spring season associate interposed involving mentioned rotatable boom fellow member and stated cord drum construction for biasing mentioned cable drum to mentioned very first situation;

the first solenoid product fitted on stated stationary thrive member and engageable with explained cable drum assemblage, when said very first solenoid device is actuated, for relocating explained cable tv drum assembly to mentioned second situation against the biasing force of said springtime associate; and

a 2nd solenoid device mounted on mentioned fixed boom member and engageable with explained cord drum set up, when stated 2nd solenoid system is actuated and explained initial solenoid system is deactuated, for transferring mentioned cable tv drum assemblage to said thirdly placement versus the biasing power of explained spring season member.

The stretch film wrapping machine as established in State 19, in which:

explained second and first solenoid devices are fitted after opposite sides of explained stationary increase associate.

The stretch film wrapping machine as set forth in a minumum of one of statements 16 to 20, wherein stated single electric motor generate arrangement further more makes up:

a plurality of very first detent recesses provided upon stated static growth fellow member;

a plurality of initially detent pins attached with explained cable television drum set up for specific disposition inside of said plurality of very first detent recesses of said static increase participant to be able to prevent relative rotation of said cable drum assembly when it comes to explained stationary growth member when mentioned cable drum assembly is disposed at said first place;

a plurality of second detent recesses offered on said rotational boom fellow member; and

a plurality of second detent pins mounted on mentioned cable drum assembly for individual temperament within mentioned plurality of secondly detent recesses of said rotational thrive member in an attempt to protect against family member rotation of said cable drum assembly with regards to stated rotational thrive member when mentioned cord drum construction is disposed at explained secondly place.

The stretch film wrapping machine as established in Declare 21, where:

said plurality of second and first detent recesses and mentioned plurality of second and first detent pins comprises 8-10 detent recesses and seven detent pins equiangularly spread out from the other person within an annular variety via an angular room of 40-five degrees (45°).
