Abstract: The modular lumber stacker utilizes a single fork and board width sensor to load layers of boards with varying widths onto a lift table. The single-fork loader allows a fork lift to readily access the opposing side of the lift table to remove a multi-layer stack of boards. An adjustable unloading stop may be used to justify the stack by distributing the dead space in each layer between the boards to justify the stack to avoid jagged stack edges and improve stacking stability.

Abstract: A lumber stacking machine has a stacking mechanism forming a stack of lumber from the bottom upwardly. The stacking mechanism includes a lift mechanism formed with a plurality of stacking fingers that lift a layer of lumber vertically above a conveyor. With the formation of a new layer of lumber, the stacking mechanism moves below the new layer with the stacking fingers retracting to pass by the new layer and resting the growing stack of lumber on top of the new layer, and then extending below the new layer to raise the entire stack to allow another new layer to be formed. Stops are provided to control the movement of the individual boards from the infeed station into the stacking station and also to control movement of the new layer beyond the stacking station. Two conveyors cooperate to move the lumber with an overlap in the stacking station.

Abstract: The invention relates to a supply device for the supply of filled sacks to a palletizing device, comprising a main supply belt for the supply of a first row of filled sacks on a sliding area of the palletizing device, wherein beneath the main supply belt at least one secondary feed belt is assembled for the supply of another row of filled sacks on the sliding area beneath a first row of filled sacks.

Abstract: Disclosed is a palletizing device (10) with a vertically mobile transfer station (14) which is in conveying communication with upstream conveying equipment (18) for conveying items, packaged goods, packages (20), or the like, to be palletized. The transfer station (14) is followed in the conveying direction (22) by a vertically mobile loading station (16) which is in conveying communication with a stacking position (28) for palletizing the items, packaged goods, and/or packages (20). The transfer (14) and loading stations (16) which are independently adjustable in the vertical positions thereof are associated with a common support structure, having separate guide devices (30) for vertically mobile guiding and drive devices for vertical position adjustment of the transfer (14) and loading stations (16), respectively.

Abstract: This invention concerns a method for horizontal movement of groups or layers of articles (10) between adjacent conveyor modules (12, 16, 34).

Abstract: A board stacking apparatus having one or more movable supports having at least two arms each, a rear stopper and a power assembly operatively connected to the movable support to move the same according to a layer stacking routine. The layer stacking routine includes positioning the movable support at a receiving position, maintaining the movable support in the receiving position while the boards are dispensed thereon, and moving the movable support in a rearward direction. The board stacking apparatus further comprises abutment components located proximate to and slightly below a board dispensing mechanism of the apparatus to support the receiving end of corresponding arms when in the receiving position.

Abstract: The invention provides an apparatus and a method for economically forming packing unit layers. The apparatus comprises at least one supply conveyor, at least one further conveyor and an exit conveyor. Furthermore, at least one gripper for positioning and/or turning the packing units is associated with the further conveyor. The positioned and/or turned packing units are brought together to form form-fitting packing unit layers by a suitable device on the at least one exit conveyor. The at least one gripper is configured in such a way that is can be used to position and/or turn at least one packing unit and that at least one further packing unit can be placed on the positioned and/or turned packing unit in the same orientation.

Abstract: A palletizer for automatically building a load with product from an infeed area is disclosed. It includes means for defining a desired volume of a load including a length sensor, a width sensor, and a height sensor. It also includes means for transporting product from an infeed area to the load. A controller is associated with means for defining the desired volume, the controller being configured to receive signals from the sensors and to automatically control movement of the means for transporting. The controller is configured to automatically determine when the volume is filled. In another aspect, a method of building a load with product from an infeed area is provided. The method includes defining a desired volume of the load using a length sensor, a width sensor, and a height sensor. It also includes automatically filling the volume with product, and determining when the volume is filled.

Abstract: An apparatus for stacking objects, provided with positioning means (3) which are designed for ranging the objects (2) in specific, substantially horizontal stacking positions (P), while the apparatus (1) is provided with conveying means (4, 14) designed for conveying the objects (2) from the positioning means to a stacking area for stacking the objects (2) onto each other, the apparatus (1) being provided with stacking pattern maintaining means (5) which are at least designed for substantially maintaining said stacking patterns (P) during the stacking of each object (2) in the stacking area. The invention further provides a method for stacking objects.
