Abstract:
Embodiments of a pusher device may include a frame, guide rails coupled to the frame, a carriage slideable along the guide rails, and a linear positioner coupled to the carriage and frame and operable to move the carriage along the guide rails. Two or more lugs may be mounted to the carriage and rotatable between a resting position, in which the forward ends of the lugs can contact the transverse supports of a tram above the carriage, and a lowered position in which the lugs can pass below the transverse supports. In the resting position, the longitudinal axis of each lug may be inclined from rear to front, such that the lugs contact the tram with the front end (as opposed to a longitudinal side) of the lugs. The lugs be generally triangular, trapezoidal, or concave polygonal in profile. Corresponding methods and systems are also disclosed herein.

Abstract:
A conveyor apparatus which allows a workpiece to be carried in and out of a desired process and lends itself to easy maintenance as well is provided. A conveyor apparatus (13) includes a first conveyance mechanism (13A) capable of carrying a board (7) into a desired process and a second conveyance mechanism (13B) capable of carrying the board (7) out of the desired process. The first conveyance mechanism (13A) includes a first conveying rod (18) adapted to reciprocate, a first pusher piece (19) fixed to the first conveying rod (18) and configured to protrude from the rod, and a switching mechanism adapted to switch the first pusher piece (19), by turning the first conveying rod (18) a predetermined angle, between an engaged position where the first pusher piece (19) engages with the board (7) and a retracted position where the pusher piece (19) is separated from the board (7), and the second conveyance mechanism (13B) includes a second conveying rod (32) adapted to reciprocate, a pusher piece (19) fixed to the second conveying rod (32) and configured to protrude from the rod, and a switching mechanism adapted to switch the second pusher piece (19), by turning the second conveying rod (32) a predetermined angle, between an engaged position where the pusher piece (19) engages with the board (7) and a retracted position where the pusher piece (19) is separated from the board.
Abstract:
A drive unit has an output subject to changing loads, where the drive unit consists of fixed and moving parts connected to a power source. The output of the drive unit is controlled in cycles, and for ascertaining the load in a given cycle, the time period required for changing the position of the moving part of the drive unit, or for changing the position of the moving part of the equipment in mechanical contact with the moving part of the drive unit, from one predefined position to another predefined position is measured, whereby the input required in the next cycle is determined according to the time period ascertained in at least one preceding cycle. Where the drive unit is an electric motor, the input required in given cycle is also determined according to electric resistance of the electric motor ascertained in at least one preceding cycle.
Abstract:
The transfer machine extends between the die-cut blank erecting station and the discharge conveyor on which the resulting boxes are carried away. It has a carriage that moves lengthwise underneath the sole plate of the various stations over which the box blank progresses. The carriage carries a system of clamps having movable upstream and downstream arms for gripping the blanks and a pusher. Together, the clamps and the pusher are used to move the blanks along the sole plate and push the box onto the discharge conveyor. The arms and the pusher are situated on a plate which is vertically movable relative to the carriage and the height of the projecting part of the upstream arms is greater than the height of the downstream arms and than that of the pushers. The upstream arm couple is hinged to the plate and pivots to allow it to retract upstream relative to the machine and beneath the sole plate. This pivoting of the arm couple is combined with the up-down movement of the plate.
Abstract:
An outfeed rail is provided. The outfeed rail assembly includes a rail arm and a pivoting abutment including a support arm attached to the rail arm and a pivoting abutment attached to the support arm. A first article is transported via a conveyor until it reaches the outfeed rail assembly. The first article moves along the roller until its momentum is stopped by the pivoting abutment. The first article rests at a stopped position until it is displaced from the stopped position by another article sent down the conveyor.

Abstract:
Apparatus and methods for handling pallets, such as for inspection and sorting, are disclosed. In a disclosed embodiment, an up-ender includes a support frame, a pallet-tilting mechanism coupled in a pivotal manner to the frame, and first and second generally upright pusher arms coupled to the frame. The pallet-tilting mechanism is pivotable between an up position and a down position, such that when the pallet-tilting mechanism is in the up position, an upright stack of pallets can be loaded onto the pallet-tilting mechanism and when pivoted to the down position, the stack is rotated about 90° so that the pallets become generally vertically oriented. The pallet-tilting mechanism also is adapted to displace the stack of vertically oriented pallets along a support surface. The pusher arms are positioned to receive the stack of pallets from the pallet-tilting mechanism and automatically index the pallets in the stack along the support surface.
Abstract:
A forward feed device for conveyor tables includes a drive element (38) that can be moved to and fro, which moves out of the table area (36) during the forward movement and back underneath it during the return movement. The drive element comprises a pivotable latch (38) that can be moved upwards out of the table area in the forward feed direction, of which the end that leads and can be raised during the forward feed movement is supported, via a link (48) with two pivoting ends, by a friction block (54) that trails behind during the forward feed movement and the return movement, and that is slowed down by friction against a stationary surface.
Abstract:
The invention is a corner unloader for a warewasher. The corner unloader includes a frame defining a corner having an inlet end and a discharge end; a pivoting carriage mounted within the frame; the carriage comprising at least two spokes and a bracket interconnecting the spokes; a plurality of pusher elements pivotally mounted to the bracket; a drive arm for providing motion to and driving the carriage; such that retraction of the drive arm causes the carriage to rotate in a counterclockwise direction and causes pusher elements to advance any racks received on the carriage from the inlet end in a direction toward the discharge end of the unloader and extension of theorize arm causes the carriage to rotate in a clockwise direction and the pusher elements pivot under the racks, whereby repeatedly extending and retracting of the carriage pushes racks through the unloader from the inlet end to the discharge end.
