Various embodiments described herein relate to controlling a conveyor that comprises at least a first zone that is upstream of a second zone. A second control module associated with the second zone receives a first signal from a first control module associated with the first zone. The first signal indicates that one of a first article that has an irregular boundary or a second article that has a regular boundary exits from the first zone. The second control module controls the second drive assembly and a second brake assembly based on the indication by the first signal.

An apparatus for transporting veneer sheets, where the veneer sheets each have an upper surface, a lower surface, and a plurality of edges connecting the upper surface to the lower surface. The apparatus includes a vacuum source and a conveyor for transporting individual sheets of veneer along a direction of travel to a predetermined location. The conveyor includes a belt running in the direction of travel. A vacuum opening adjacent the belt is in communication with the vacuum source to draw respective sheets of veneer to the belt by suction applied to the upper surface or the lower surface of the veneer sheets via the vacuum opening. The position of the conveyor is adjustable in a direction transverse the direction of travel to accommodate veneer sheets having different lengths.

Methods for preparing parcels for final sorting. The methods include dividing a mass flow of parcels into individual streams, separating and singulating the parcels in each stream, delivering each stream at a steady rate to a human operator that faces and culls the parcels, reading identifying indicia on the parcels, delivering the scanned parcels to a presorter in parallel lanes, and selectively discharging parcels from the lane closest to a side of the presorter off the side at multiple discharge points.

A method for counting and aggregating a pre-determined number of articles includes: driving, by a conveyor, an article stream to move to an end of the conveyor in a single layer state; conveying the article stream in a periodic motion; after the articles in the article stream leave the conveyor, accurately counting the number of the articles; and when a total number of articles in a combination of temporary storage bin is the same as a target number, transporting all articles in the combination of temporary storage bin to a storage device. Article batches are separately delivered to different temporary storage bins, and the total number of articles in temporary storage bins in different combinations is calculated, so as to obtain with a combination in which the number of articles is the same as the target number. The operation efficiency is improved and the manufacturing cost of device is reduced.

This article transfer apparatus comprises a disk member, an article supply apparatus which changes at least positions of the respective articles at a predetermined circumferential position of the rotating disk member, a rotation sensor which detects a rotational position of the disk member, a visual sensor which obtains information for identifying at least positions of the respective articles on the disk member, and a robot which picks up the articles on the disk member in a state in which the disk member is rotating, by using an article position information in which the information obtained by the visual sensor corresponds to a detected result of the rotation sensor at the time of obtaining the information, and a detected result of the rotation sensor at the time of picking up the articles.

Embodiments provide a conveyor for conveying loads of lumber through a lumber kiln or other structure without the use of lumber carts or pushers. The conveyor may include a plurality of rollers arranged to form a flow path through the lumber kiln. Groups of the rollers may be driven by separate drives that are configured to rotate the rollers in opposite rotary directions and/or at variable speeds. Some or all of the drives may be operable independently of the other drives to transport loads of lumber at different speeds/directions in adjacent areas of the lumber kiln. In the event of a fire or a shut-down, the rollers in the proximal half of the kiln and those in the distal half of the kiln can be rotated in opposite directions to evacuate loads quickly from both ends.

A feeding mechanism and method for feeding objects singulated from a bulk mass of objects includes receiving the bulk mass into a hopper system having a hopper screw set including first and second hopper screws and a plurality of feeding pockets defined by the thread forms of the hopper screws. Rotation of the hopper screws tumbles the bulk mass to cascade and singulate individual objects into respective feed pockets. An object set including at least one singulated object is discharged from the hopper screw set by rotation of the hopper screws. A discharge assembly including a ramp and star wheel receives the discharged object set, and transfers the object set to a discharge outlet. The object set output from the discharge outlet is received by a target defined by a receiving article. In one example, the object is rounded, the target is an opening of a container.

A product packaging system comprises a plurality of product sources (2, 4, 6) delivering product to a final collating and packaging line (10). The output from each machine is delivered by separate conveying means (8) delivering the products directly into a collating conveyor (20) which in turn delivers the collated products to a packaging line. The collating conveyor comprising an endless conveyor carrying a plurality of compartments, each compartment receiving from said conveying means products to be packaged. The compartments are configured to enable their sizes to be changed, and the endless conveyor comprises a track arranged in a vertical loop and a plurality of product supporting members mounted for movement along the track, each supporting member being driven along the track and controllable independently of the other supporting members.

The present disclosure provides systems, methods and assemblies comprising one or more tapered feed rolls. Tapered feed rolls may be used to change the rate and direction of workpiece travel along a processing line while retaining the workpieces in sequential order. Routing workpiece flow with tapered feed rolls may allow the workpieces to be tracked along one or more processing lines, and may reduce the operational space required for workpiece processing.
