A conveyor includes a plurality of belt support assemblies each having a drive wheel assembly at one end and an idler wheel assembly at the other end. Each of the drive and idler wheel assemblies includes a motion converter for converting the rotational movement of a shaft into linear motion along the shaft and an actuator for selectively engaging the motion converter and the shaft. A controller controls the operation of the shafts and the actuators to selectively and individually control the location of each end of each belt assembly relative to one another and to a centerline of the conveyor.

A conveyor system includes an external ball-belt and an internal driver belt for driving balls in the ball-belt. A first drive drives the ball-belt in the longitudinal direction, and a second drive drives the driver belt in a transverse direction. The second drive is located outside the ball-belt and located such that a return portion of the ball-belt runs between the second drive and the driver belt.

A sheet stacking system for transporting sheets and depositing them in a stack includes a layboy, a transport conveyor downstream of the layboy, and a main conveyor downstream of the transport conveyor, the main conveyor having a frame and being supported by a conveyor support, a discharge end of the main conveyor being movable between a lowered position and a raised position relative to the conveyor support. The main conveyor intake end is configured to move from a first position when the main conveyor discharge end is in the lowered position to a second position when the main conveyor discharge end is in the raised position, and also a variable length conveyor between the transport conveyor and the main conveyor, the variable length conveyor having a discharge end connected to and movable with the main conveyor intake end and movable relative to the transport conveyor discharge end.

A conveyor configured to transport sheets along a transport path from an input end to a discharge end includes a main frame, an upper conveyor deck supported by the main frame and having a plurality of belts and a lower conveyor deck supported by the main frame and having a plurality of wheels. The transport path is defined by the contact surfaces of the plurality of belts in the first contact region and the contact surfaces of the plurality of wheels in the second contact region, and the conveyor is configured such that the sheets make direct contact with the contact surfaces of the plurality of belts and make direct contact with the contact surfaces of the plurality of wheels when the sheets move along the transport path. The wheels are shiftable in the third direction relative to the belts and relative to the main frame.

A conveying apparatus includes an upper conveyor and a lower conveyor, the top of the lower conveyor facing the bottom of the upper conveyor and defining with the bottom of the upper conveyor a sheet transport path. An air duct having an opening facing the top of the upper conveyor is mounted over the upper conveyor, and a fan is provided that is in fluid communication with the air duct. The fan draws air through the opening, into the air duct and out an exhaust vent. A housing substantially encloses the upper conveyor and the lower conveyor and is connected to the air duct, and the housing has a bottom opening located below the sheet transport path such that a majority of the air drawn through the opening by the fan passes through the upper conveyor.

A load former includes a loading zone, a stacking zone adjacent to the loading zone, a platform in the stacking zone, a first drive configured to raise and to lower the platform, and a cookie sheet having a first portion and a second portion adjacent to the first portion. The cookie sheet is shiftable from a first position in which the first portion of the cookie sheet forms a floor of the loading zone and the second portion of the cookie sheet is not located in the loading zone or in the stacking zone and a second position in which the first portion of the cookie sheet extends directly above the platform in the stacking zone and the second portion of the cookie sheet forms the floor of the loading zone. A second drive shifts the cookie sheet between the first position and the second position.

A system includes an electrical panel having a high voltage compartment and a low voltage compartment and a first door shiftable between an open position allowing access to the high voltage compartment and a closed position preventing access to the high voltage compartment and a lock shiftable from a locked position to an unlocked position by an actuator in response to a receipt of an unlock signal. A main disconnect switch outside the electrical panel selectively connects a source of electric current to the electrical panel, and a sensor detects a position of the main disconnect switch and sends an unlock signal to the first actuator in response to a detection that the main disconnect switch is in an OFF position.
摘要:
A diverter conveyor includes a frame supporting an upper conveyor that has an upstream end and a downstream end and that is configured to carry sheets in a first, downstream, direction. A plurality of nip rollers are mounted on the frame upstream of the upstream end of the upper conveyor and are spaced from the upstream end of the upper conveyor by a gap. The nip rollers feed the sheets along a main path to the upstream end of the upper conveyor. A rejection conveyor is supported by the frame and has a portion beneath the gap and extends away from the upper conveyor at an acute angle. A plurality of paddles are mounted at the first gap, and an actuator is operably connected to the paddles and configured to shift the paddles from a first position out of the main path to a second position in the main path.
