Abstract
A device that is usable to change the direction of a transport assembly, on which feed roller may be transported, includes a lower section and an upper section. The upper section is pivotally mounted on the lower section. The transport assembly is arranged on the side or on the top of the upper section and the upper section can be pivoted by an angular amount, relative to the lower section, by use of a drive unit. A drive motor of the drive unit has its output transmitted to the upper section by a drive belt. A positive drive exists between the motor and belt and a friction drive exists between the belt and the upper section.
Claims20
A device for changing a direction of travel of a conveying means, said device comprising:
- a lower element and an upper element, said upper element being supported on said lower element for swivelable movement with respect to said lower element, said upper element being adapted to receive the conveying means;
- a drive mechanism usable to swivel said upper element with respect to said lower element, said drive mechanism including a drive belt;
- a driving disk having a smooth faced circumferential surface on said upper element, said drive mechanism being positively connected with said drive belt and said circumferential surface being in frictional engagement with said drive belt;
- and
- means for varying a tension in said drive belt and for decoupling said drive mechanism and said upper element.
A device for changing a direction of travel of a conveying means, said device comprising:
- a lower element and an upper element, said upper element being supported on said lower element for swivelable movement with respect to said lower element, said upper element being adapted to receive the conveying means;
- a drive mechanism usable to swivel said upper element with respect to said lower element, said drive mechanism including a drive belt;
- a coupling device interposed between said drive mechanism and said upper element, said coupling device being shiftable between a first operating state in which said drive mechanism and said upper element are kinematically coupled, and a second operating state in which said drive mechanism and said upper element are kinematically decoupled;
- a tensioning roller in said coupling device, said tensioning roller being movable between a first, drive belt tensioning position, and a second, drive belt untensioning position, said drive belt exerting a frictional driving force on said upper element in said first drive belt tensioning position of said tension roller, said drive belt being sufficiently frictionally disengaged from said upper element in said second drive belt untensioning position of said tensioning roller to allow said swiveling movement of said upper element;
- a pivot arm, said tensioning roller being supported on said pivot arm;
- a shaft, said pivot arm being supported on said shaft for pivotal movement with respect to said shaft;
- and
- a recess having a bottom, a lower end of said shaft being secured to said bottom of said recess, an upper end of said shaft being engageable from above said recess.
