The invention relates to a firewood handling device for firewood pieces (6), comprising a conveyor (1), including one or more rotating, endless chains (9), wherein the conveyor extends from an input end (2) to an output end (4). The conveyor chains are provide with carriers (10), which project outwards from the outer sides of the chains and extend across and on a distance from each other in relation to the longitudinal extension of the conveyor such that spaces are formed between the carriers into which firewood pieces (6) can be positioned having their longitudinal extension across the longitudinal extension of the conveyor. The carriers (10) are formed with at least two, not cut through slots or recesses (42, 43, 44) from below as well as from above which overlap each other, wherein the conveyor (1) in its output end (4) is provided with at least two inner guiding members (45) as well as with at least two outer guiding members (46). Both the inner and the outer guiding members are provided with smooth upper sliding surfaces and are mounted such that the sliding surfaces (45′) of the inner guiding members extend and have an increasing height in the conveying direction and are positioned such that they are aligned with the slots or recesses extending from below in the carriers, whereas the sliding surfaces (46′) of the outer guiding members extend and have a decreasing height in the conveying direction and are positioned such that they are aligned with the slots or recesses extending from above in the carriers, and wherein the sliding surfaces of the inner and the outer guiding members extend essentially without interruption or somewhat overlapping in relation to each other as seen in the conveying direction.

A method of constructing a conveyor system includes decommissioning an existing conveyor system by removing electrification or a powered chain from a conveyor rail. Carriers of the existing conveyor system are removed from the rail. An automated conveyor carrier (ACC) is installed onto the rail so that a drive wheel of a self-driving trolley of the ACC is put into contact with the rail. A battery is installed on the ACC. Electrical connection is established from the battery to the self-driving trolley.

A cleaning pig assembly is provided for use on a tubular drag conveyor. The assembly is quickly and easily mounted anywhere along the cable, chain, or rope via slots in the assembly components. The components include a puck, a plate, a drag disc, and a cleaning member or tool sandwiched between the puck and the plate. The drag disc provides interference fit on the cable, chain, or rope holding the assembly on the cable, chain, or rope and prevents sliding of the assembly along the cable, chain, or rope during use. The cleaning assembly is installed without the use of tools or clamps. Multiple interchangeable cleaning members are provided depending on cleaning needs.

A conveyor system includes a fixed, non-powered rail defining a conveyor path. An automated conveyor carrier (ACC) is supported by the rail and drivable along the rail by an on-board motor in a self-driving trolley of the ACC, the motor powering a drive wheel. The rail defines a first section and a second section separate from the first section. The conveyor system is adapted to provide a first amount of traction for the ACC on the rail in the first section and a second amount of traction, greater than the first amount of traction, in the second section.

A method of operating a conveyor system includes providing a fixed, non-powered first rail supporting first and second trolleys of a first carrier, at least one of which is self-driving. The first and second trolley are conveyed in line along the first rail with a load bar therebetween. The first carrier defines a length measured along the first rail and a width measured transverse. The first carrier is conveyed to a branch point where a second rail branches from the first rail. The second trolley is conveyed along the second the rail to turn the first carrier so that it is conveyed with the load bar traversing between the first and second rails. The width is substantially less than the length such that the turning of the first carrier reduces an occupancy of the first carrier along the first rail.

A conveyor system including a fixed, non-powered rail defining a conveyor path, and a plurality of automated conveyor carriers supported on the rail. Each carrier includes an on-board motor and electrical power source selectively powering the motor to drive the carrier along the rail. Each of the plurality of ACCs operates to power the on-board motor from the on-board electrical power source under the direction of instructions programmed to a local controller on the respective ACC. Wherein each of the local controllers of the respective ACCs is programmed to carry out independent power level management for its own on-board electrical power source and configured to selectively operate an adaptive low power indicator to communicate a low power status based only in part on the power level of the on-board electrical power source and further based on one or more parameters of a current work cycle.

An automatic tensioning apparatus is provided that includes a tensioning drive unit having: a longitudinally extending stationary base frame with a plurality of guides extending between a lower portion and an upper portion, and a plurality of rotatable feed wheels axially secured at the lower portion, as well as a translatable drive frame slidably coupled to the plurality of guides with a drive assembly coupled to the drive frame, the drive assembly including a drive motor and a tensile member interface for engaging and rotationally translating a tensile member. The tensioning drive unit further including a plurality of drive frame actuators actuatable to move the drive frame between a bottom frame position and a top frame position, as well as a sensor for at least indirectly sensing the position of the drive frame along a longitudinal base frame axis.

A feeding device for feeding products from a storage container on to a conveyor belt moving in a conveyor direction is provided wherein a feeding belt at a storage container opening on a lower side of the storage container receives products to be conveyed and transports them to an upper side of the conveyor belt, in order to deliver the products on to the conveyor belt in a feeding region on the upper side of the conveyor belt, the feeding belt has a number of holes, the dimensions of which are adapted to the products to be conveyed such that a respective product can fall through an associated hole. A guiding element extending from the storage container opening to the feeding region on the upper side of the conveyor belt, including a guiding surface arranged directly below the feeding belt, is arranged on a lower side of the feeding belt in such a way that the guiding surface prevents the products from falling through the holes of the feeding belt until the products are delivered on to the upper side of the conveyor belt in the feeding region. The holes are arranged in the feeding belt in a matrix shape. The guiding surface of the guiding element forms a low-friction and abrasion-resistant flat sliding surface.

A conveyorized industrial system includes at least one work station including a heated oven chamber. A fixed, non-powered rail defines a conveyor path including an oven zone in which the rail extends through or over the heated oven chamber. An automated conveyor carrier (ACC) is suspended from the rail by a self-driving trolley having an on-board motor for driving the ACC along the rail, and by at least one additional free-rolling trolley. The ACC further comprises an enclosure containing one or both of an inverter and a battery, the enclosure having a wall defining an interior space of the enclosure. A heat protection system is provided in addition to the wall, the heat protection system operating to limit an internal temperature of the enclosure during transport along the oven zone.
