A nail punching machine for driving in or pulling out rail spikes comprises a driving mechanism, which is driven by means of an electric drive motor. The electric drive motor is supplied with electric power by means of an accumulator. The nail punching machine is held by an operator by means of at least one handle.

Method and systems of automated document processing described herein include activating in sequence a plurality of illumination modules of an illumination source to illuminate a document, where the plurality of illumination modules are located at different positions relative to the document. The document can be imaged each time the document is illuminated by an illumination module to provide a plurality of images. A shadow profile of the document can be obtained based on the plurality of images. One or more of a boundary of the document and presence of a fastener attached to the document can be identified using the shadow profile. Any fasteners present may be removed using a robot arm.

A plying tool includes a main body including a first joining portion and a second joining portion and a plying member set including a first and second plying member movably and releasably connected with the main body. The first and second plying members are movable relative to each other and adapted to connect with the main body in a first arrangement with the first plying member connected with the first joining portion and the second plying member connected with the second joining portion respectively, and a second arrangement with the first plying member connected with the second joining portion and the second plying member connected with the first joining portion respectively.

A staple removing device configured to remove a staple from a sheet bundle bound by the staple, the staple removing device includes a support part comprising a placement surface capable of placing the sheet bundle thereon, an insertion part configured to be insertable between the sheet bundle and the staple in a state in which the sheet bundle is supported on the support part, and configured to remove the staple from the sheet bundle by the insertion, and a controller configured to control an operation of the insertion part. The controller is configured to reciprocally move the insertion part multiple times between the sheet bundle and the staple in a process of removing the staple from the sheet bundle.

A method includes: receiving a recycled wood workpiece populated with a set of metal fasteners; accessing an internal imaging scan; detecting the set of metal fasteners embedded in the recycled wood workpiece based on internal features detected in the internal imaging scan; for each metal fastener in the set of metal fasteners, extracting an initial position and an initial orientation of the metal fastener from the internal imaging scan; generating a virtual model of the recycled wood workpiece based on the internal imaging scan; accessing an image captured by an optical sensor; detecting a first metal fastener in the recycled wood workpiece; deriving a first position and a first orientation of the first metal fastener; and, in response to identifying the first metal fastener analogous to an initial metal fastener in the virtual model, isolating the first metal fastener in the virtual model and generating a fastener removal schedule.

A fulcrum prybar includes a shaft portion extending along a first axis, a curved prying portion affixed to a first end of the shaft portion, and a fulcrum portion affixed to the curved prying portion. The fulcrum portion includes two rectangular portions fused together to form an obtuse angle or a right angle cross section. One of the two rectangular portions is oriented such that it is flush with a horizontal surface while the prybar has partially raised an object from the same or another horizontal surface.

A powered tool includes a body, a cylinder, an impact piston reciprocating within the cylinder, and a mount to secure an attachment. The attachment includes a shank and a head sleeve fit over the shank and extending beyond its front end. The head sleeve includes a nozzle at its front end having a slot terminating at a muzzle. An internal hold in the head sleeve is in open communication with the slot. The front end of the shank is disposed within the internal hold and reciprocates therein. A rod is carried within the head sleeve for reciprocal movement in response to reciprocation of the shank with respect to the head sleeve. The rod includes a tongue extending from the internal hold into the slot of the nozzle. The tongue terminates inside the slot for reciprocal movement within the slot in response to reciprocal movement of the shank.
