The automated saw comprises a bandsaw blade, a controller, a visual sensor and a meat positioning assembly. The controller comprises a computer comprising an address space, and a processor, a memory. The controller stores a device application in the memory and runs the device application on the processor. The meat positioning assembly comprises a pusher and a tray configured to move the uncut meat relative to the bandsaw blade. The tray is configured to hold the uncut meat. The pusher is configured to slide the uncut meat through the tray. The meat positioning assembly is configured to move the tray in a forward direction and a rearward direction relative to the bandsaw blade.

A band saw machine for sawing metallic workpieces, having a lower saw part and an upper saw part with two carrying wheels mounted therein, and a saw band that revolves with a cutting motion around the wheels that passes through a cutting region. A feeding device attached to the lower saw part feeds workpieces to the cutting region and/or into a sawing plane, in which the cutting region of the saw band is moved in a saw advance motion. The feeding device has a movable holder for detachably fastening the workpiece, and the holder, starting from an initial position, is movable both with translational and rotational motions. The saw band is guided through the cutting region, and the holder is moved translationally against the cutting region in order to execute the saw advance motion. Here, the workpiece is preferably turned by the holder such that its upper side faces downward.

A profiling saw with band knife loop take-up and payoff compensation includes an endless circulating band knife which is guided around a plurality of band knife pulleys so the take-up and payoff adjustment is provided of the loop circulation path shape. The take-up and payoff system operates to move a pulley in the vertical plane for allowing the band knife to maintain its cutting orientation during movement and providing for more rapid and precision cuts into a workpiece.

A feeding device for a machining device includes a support unit, a feeding unit, and a connecting unit. The feeding unit is adapted for feeding a workpiece to be machined by the machining device. The connecting unit is connected between the support unit and the feeding unit, and includes a positioning member pivotally connected to the support unit and extending in a longitudinal direction, an adjusting member telescopically connected to the positioning member and movable relative to the positioning member to adjust a distance between the feeding unit and the support unit in the longitudinal direction, and a locking unit for releaseably locking the adjusting member on the positioning member.

The present disclosure provides for an apparatus for using continuous, preferably smooth, bandsaw blades to cut a substrate. The current disclosure also discloses using the same for preparing a safe and efficient method for cutting substrates into rolls.

A band saw machine has two deflection pulleys arranged one above the other in the vertical direction, an endless saw band, which is guided around the deflection pulleys and which has an upward running portion and a downward running portion, and a machine frame, which has a saw neck for holding at least the upper deflection pulley. The deflection pulleys are arranged substantially parallel to a front edge of the machine frame, so that both the upward running portion and the downward running portion of the saw band face towards the front edge with their cutting edges. The saw neck is arranged offset from the deflection pulleys from the front edge (6) to the rear. Both the upward running portion and the downward running portion of the saw band are at least partially exposed between the deflection pulleys.

An automated saw for assessing an uncut meat and calculating a one or more cutting depths and cutting a one or more cut portions. The automated saw comprises a bandsaw blade, a controller, a visual sensor and a positioning system. The positioning system comprises a pusher and a tray configured to move the uncut meat relative to the bandsaw blade. The tray is configured to hold the uncut meat. The pusher is configured to slide the uncut meat through the tray. The positioning system is configured to move the tray in a first horizontal direction and a second horizontal direction relative to the bandsaw blade. The uncut meat comprises a first end and a second end. The first end of the uncut meat comprises a surface area and a diameter.

A method for controlling a sawing machine is provided. For a first cut in a workpiece, a working feed rate that is specific to the workpiece geometry, the workpiece material and the sawing tool is defined in advance. During the first cut, an instantaneous value of a physical variable is determined at a frequency converter, that is related to the torque transmitted by the sawing tool drive to the sawing tool, and this value is transmitted as an instantaneous torque value to a machine controller. The instantaneous torque value is continuously evaluated, a maximum torque value of the first cut is determined and a maximum value for the torque value is defined based thereon. For subsequent cuts in the same workpiece, the working feed rate is regulated, using the instantaneous torque value as a regulating variable, such that the instantaneous torque value is kept constant, close to the maximum valve.

A device and method are disclosed. An embodiment of a sliding sled for use on a saw table includes a flat plate, adjustable guide fences on the flat plate at a fixed pivot end to create an oblique angle relative to the saw table, an indexing system including angle indicators to set the angles of the adjustable guide fences, roller bearings on the bottom side of the flat plate for riding on the ACCU-SLICE rail, and a sawdust shield to keep sawdust off the roller bearings and ACCU-SLICE rail. Guide fences may have a fixed pivot end and a movable end and a locking bolt to temporarily fix the movable end at a desired position on the plate. The movable end of the adjustable guide fences may align with the angle indicators when the angle of the adjustable guide fence relative to the cutting plane corresponds to the angle indicators.

Systems and methods for improved bandsaw process control and throughput, in which a sawblade of a bandsaw contacts a bottom sawguide mounted in a bottom guide holder, the bottom guide holder frame having a flexural member that transmits forces on the sawguide to a force transducer associated with the flexural member. Workpiece-related forces include deflection forces, both lateral and torsional, and saw resistance forces on the bottom sawguide. An object of the invention is to establish a true cut condition when pre-straining the sawblade and a process control loop whereby the true cut condition is restored in near real time while cutting a workpiece. The combination of a force sensing guide holder and a process control loop synergically improves target lumber size control and maximizes log value, while also increasing throughput by reducing both overfeed and underfeed.
