automatic upside film dispenser for door wrapping machine
A prominent conclusion of online 14 is mounted on fill 50 or perhaps a clamp on turntable 36. Relative to web dispenser 12, web 14 is stretched, wrapped and dispensed around the load, as platform 36 and load 50 is rotated about a vertical axis.
As shown in FIG. 1, online 14 is dispensed along vertical sides 51 of weight 50 although website dispenser 12 and web 14 is maintained inside a top to bottom orientation typically parallel with sides 51. Edges 51 are spirally packaged by moving dispenser 12 within the straight path when turning stress 50. Soon after aspects 51 are twisted, a series begins to wrap the very best 53 of stress 50.
As proven from the pattern of FIGS. 4, 5, 3 and 2 just soon after internet 14 passes by a area 54a of the load 50, dispenser 12 is increased above the top of stress 50 by driving belt 72 with motor unit 74. All at once, water cylinder 32 is actuated to improve the orientation of internet dispenser 12 coming from a top to bottom orientation usually parallel with aspects 51 to your horizontal orientation usually parallel with top 53 of stress 50.
A portion of web 14 engages the corner 54a of the load between the side 51a and side 51b of load 50, as web dispenser 12 is raised. Online dispenser 12 continues to be raised and rotated right up until it can be over the leading 53 from the fill 50 and also in a horizontal orientation generally parallel to the peak 53 from the fill 50. Online dispenser 12 is managed within this horizontal orientation although stress 50 will continue to turn, creating the internet 14 to overlie a portion of top 53 of load 50 and engage the very best edge of aspect 51b.
As shown inside the pattern of FIGS. 4, 5 and 3 dispenser 12 is lowered below the best 53 of load 50 following online 14 moves 2nd corner 54b and before it moves third corner 54c to ensure that website 14 engages the top edge of side 51c. If at all possible, at the conclusion of the decreasing functioning, fluid tube 32 is actuated to change the orientation of online dispenser 12 from a horizontal orientation usually parallel to the top 53 of load 50 to a straight orientation typically parallel on the edges 51 of your fill as fill 50 is constantly rotate, departing a toned part of website covering a portion of leading 53 of fill 50 among leading corners of aspects 51b and 51c.
