Abstract:
A stacking apparatus includes a feed device that feeds a succession of elongated items to a pick-up station, and a rotating structure having first and second arms at different angles about a rotation axis of the rotating structure. The arms have receiving surfaces mounted thereto that receive the elongated items as a layer at the pick-up station during rotation of the rotating structure as the receiving surface travels past the pick-up station. The apparatus also includes a carriage having layer supporting forks that receive the layer from the receiving surface during rotation of the rotating structure as the receiving surface travels past a layer receiving station. The carriage carries the layer from the layer receiving station and deposits the layer at a layer stacking station from the forks to form the stack of superimposed layers.
Abstract:
A device (10) for orienting tubular cores made of card for supporting rolls of toilet or kitchen paper includes elements for imparting an angular movement to each long item (11) in such a way that it is fed out of the device at a suitable angle. The elements for the angular orientation of the item (11) are designed to cause the item to be fed forward while keeping it substantially-transversal to the direction of feed and include first mobile members (12) for feeding a corresponding portion of the item (11) and extending along a respective path, which has a curved section (12a), and second mobile members (14) for feeding a second portion of the item (11) and extending along a respective path having a curved section (14a) which is concentric with and radially inside the curved section (12a) of the first mobile feed members (12).
Abstract:
An apparatus for selecting and sorting a plurality of random length boards to form at least one row of boards having a total length within a predetermined target length range includes a measurement section operative to measure the length of each board and a sorting section which includes a sorting device and system for sorting the boards. An accumulating row section accumulates and stores rows of boards selected from the plurality of boards and a vacuum suction transport device moves rows of boards from the accumulating rows to a bundling section which receives rows of boards and then bunches and aligns the rows of boards and bundles the rows of boards in a board row bundle. Finally, a central processor performs all calculations and controls to properly sort the boards to create bundles of rows of boards having a total length generally within a predetermined target length range.
Abstract:
A method and apparatus of turning a board while the board is being transferred in a conveyance system includes a conveyance system for transporting a board, a rotary turning device for rotating the board, a bumper stop for restraining the board and a speed-up belt for increasing or decreasing delivery of the board. The rotary turning device rotates at a constant rate relative to the conveyance system speed; the bumper stop stops the flow of the lumber allowing the rotary turning device to pick up the board; the speed-up belt accelerates the board to the front of the lug space and the conveyance system transports the board while it is turned within the lug space.
Abstract:
A stacking system 1 has eleven pairs of right and left uprights (11, 12). They are supported upright by crosspieces (14, 15, 16), there being two straight crosspieces (14) and two cranked crosspieces (15, 16). The straight crosspieces have three pairs of uprights, whilst the crosspiece (15) has two pairs and the crosspiece 16 has three pairs. This particular arrangement allows five differing lengths of tubes T1-T5 of successively longer length to be stacked. The length of the tubes is parallel to an axis L. The uprights are square section tubular steel with slots (18) in their faces facing each other in their pairs. The slots extend from close above their lower ends to a little short of their upper ends, which are bevelled inwards (19) in the pairs.
Abstract:
A caterpillar traction apparatus (110), wherein two pairs of pulleys (122 & 123, 132 & 133) can be driven at different speeds, so that the linear member (40) being driven by the mechanism is subjected to either compression or extension forces.
Abstract:
A high-speed stacker preferably includes dual stacking arms configured to operate complementary to one another. Most preferably, an electronic control system is provided to enable precise control over the speed and positioning of the stacker arms in both horizontal and vertical orientations. Linear motion devices (such as hydraulic cylinders, screw drive linear actuators, or other devices) can be used to position the arms horizontally and vertically in response to instructions from the electronic control system. In operation, the electronic control system preferably controls the speed and ramping of the stacker arms to repeatedly move courses of material from a feed system to a stacking area at a rapid rate with little maintenance. The high-speed stacker can also be configured to operate fewer than all of the stacker arms to facilitate faster stacking of smaller courses of material.
Abstract:
The invention involves a carpet retractor for moving rolls of carpets, pipes, conduit and other tubular elements. The carpet retractor includes an elongate member to which the other components of the carpet retractor are coupled, a plurality of gripping members adapted to engage the inner surface of a roll of carpet, and an engagement mechanism configured to actuate a plurality of gripping members so as to facilitate the movement of rolls of carpet.
Abstract:
The invention is an automatic, unmanned, powered, variable speed transfer table for a finger joint machine which receives a controlled supply of blocks from a lineal block feeder The slat chain is composed of two chain loops, connected at regular, equal intervals by slats. The slat chain pushes blocks over an even ending conveyor which aligns them to the inside of one of the chains and then over a moisture detecting system. Blocks containing unacceptable moisture fall through a gap in the working table while blocks with acceptable moisture are pushed by the slats over a door covering the gap and onto an outfeed table. The slats are synchronized to the lugs on the finger joint machine's lug chain and deposit correctly aligned and orientated blocks precisely on the lug chain. The slat chain then rotates upward and loops back over the working table and then down, under the infeed conveyor to re-emerge at the even ending conveyor. 1 InventorStibbard; James S.

Abstract:
A board unscrambler for lumber processing provides an upwardly and forwardly extending S-shaped curvilinear conveyor with a rearward horizontal portion to receive an agglomeration of scrambled boards, a medial uprising portion to unscramble and align the boards and a forward portion to deliver the boards at an elevated position. The conveyor provides at least two spaced link chains and interconnecting bars that are carried on an S-shaped conveyor support surface defining spaced parallel open top channels where each link chain is supported and maintained by synchronously driving both the lower rearward input portions of the chains to push the lower chain portions and the upper output portions to pull the upper chain portions to maintain the chains in the channels without vertical restraints. The unscrambled boards are delivered in an aligned single layer from the forward elevated portion of the conveyor.
