摘要： A method for moving a mold assembly from a mounted position within a concrete products forming machine includes extending an extraction assembly forwardly from a retracted position at a rear of the concrete products machine to an intermediate position so that terminal ends of the extraction assembly are positioned below a carrying surface of the mold assembly. The extraction assembly is raised at the rear portion of the concrete products machine so that the terminal ends of the extraction assembly contact and raise the carrying surface of the mold assembly up off mold mounting surfaces on the concrete products machine. The extraction assembly is then moved to a fully extended position so that the mold assembly is moved forwardly from the mold mounting surfaces to an operative position whereby the mold assembly can be removed from the extraction assembly and replaced with a replacement mold assembly.

摘要： An apparatus for delivering a wet concrete mix to a product mold, where the apparatus comprises a hopper configured to retain a fresh concrete mix, a source of treated water having a concentration of nanobubbles of a gas at least double a natural concentration of nanobubbles of the gas within a natural state of the water, a water transport coupling the source of treated water with the hopper, a valve interposed within the water transport for selectively releasing the treated water into the hopper, and a mixer in communication with the hopper for mixing the treated water with the fresh concrete mix to yield an infused wet concrete.

摘要： A compression shoe for use on a concrete products forming machine comprises a main body and a plated layer overlaid on the main body. The main body is configured to be slidingly received within a mold cavity of a concrete products mold. The plated layer overlaid on the main body of the compression shoe comprises a uniform electroless nickel (Ni), phosphorus (P), and polytetrafluoroethylene (PTFE) nano dispersion coating to effect enhanced material release characteristics by preventing the build-up of material on the compression shoes and enhancing their wear characteristics.

摘要： An automated mold change system, for use with a concrete products machine of a type having a products forming section and a feedbox assembly section, includes a mold exchange assembly coupled to an underside of the feedbox assembly section and vertically moveable therewith, a mold transfer assembly on an opposed side of the products forming section from the feedbox assembly section, and mounts on the products forming section configured to retain a mold assembly thereon. A mold exchange path runs axially between the mold exchange assembly and the mounts on the products forming section and intersects a mold transfer path of the mold transfer assembly at a load-unload position, wherein the mold exchange assembly is configured to lift a mold off of the mounts and onto the mold transfer assembly at the load-unload position.

摘要： A hoist safety lock mechanism includes a pair of pawls formed on terminal ends of each corner of a pallet support structure. The pawls are biased outward to an extended position and include a lower support surface adapted to rest on a support surface. The pawls may be pivotally deflected downward (but not upward) due to impact on a top surface of the pawl. Each pawl is configured to be received within a respective parallel column of slots formed on inwardly-facing sides of the vertical posts forming the lifting frame of the hoist. The slots within each column are vertically offset and separated by separators which can vertically deflect the pawls. Because the slots are vertically offset, and because each terminal end includes a pair of pawls, there is always at least one pawl engaged within the slot even if the other of the pair is deflected by contact with a separator. Thus, any failure of the hoist will cause the pallet support structure to only fall to the next lower separator before the pawl catches it.
摘要翻译：起重机安全锁定机构包括形成在托盘支撑结构的每个角的终端上的一对爪。棘爪向外偏压到延伸位置，并且包括适于搁置在支撑表面上的下支撑表面。棘爪可以由于冲击到棘爪的顶表面而向下（而不是向上）枢转地偏转。每个棘爪构造成被容纳在形成在起重机的提升框架的垂直支柱的向内侧的相应的平行的槽中。每列中的槽由垂直偏转爪的分隔器垂直偏移并分隔开。由于槽是垂直偏移的，并且由于每个终端包括一对棘爪，所以即使该对中的另一个通过与分离器接触而偏转，总是存在至少一个卡爪接合在槽内。因此，起重机的任何故障将导致托板支撑结构仅在棘爪抓住之前落到下一个较低的分离器上。

摘要： A method for exchanging molds in a concrete products forming machine (CPM) comprises moving a first mold cassette assembly along a linear path to a mold receiving position adjacent to a concrete products forming machine. The first mold is then moved out of the CPM along a mold-transfer path perpendicular to the linear path of the first mold cassette assembly. The first mold is then mounted within the first mold cassette assembly which then moves along the linear path out of the mold-receiving position. The second mold cassette assembly, and pre-mounted second mold, are then moved along the linear path to the mold-extracting position. The second mold is then demounted from the second mold cassette assembly and moved along the mold-transfer path to the concrete products forming machine to effect a mold change within the CPM.

摘要： On a conveyor for articles traveling from an upstream to a downstream end, an assembly for turning articles is integrated for changing the orientation of the article so that the article may be proper positioned within a stack of such products on a pallet layer. The turning assembly comprises an arm that is selectively extendible along a track to a plurality of extendable positions into an article path on the conveyor. The arm includes an upstream contact surface that is configured to contact a downstream surface of the article off-axis to a center of gravity of the article so that the article rotates about the upstream contact surface to a turned position and continues downstream on the conveyor in the turned position. A turn assist plate pivots into contact with an upstream portion of the article under computer control as needed to assist with turning boxes that are particularly long.

摘要： A mold assembly for forming concrete products comprising a mold box having cavities for receiving and molding concrete products and a mounting bracket extension coupled to each side wall of the mold box and forming a lower mounting surface of the mold box. Die alignment holes are formed in an underside of each mounting bracket extension and are configured to receive alignment dowels extending upward from shelves of the concrete products forming machine on which the mold box sits. The mounting bracket extensions further include mold transfer locators formed on the underside inward of the die alignment holes so that they are exposed from below when the mold assembly sits on the shelves of the concrete products forming machine. These locators are configured to locate the mold assembly onto mold extractor arms when the mold assembly is lifted off of the alignment dowels by the mold extractor arms during a mold extraction process.

摘要： A mold transfer assembly comprises a carriage assembly configured to be placed adjacent a concrete products forming machine. The carriage assembly has a track running along a mold-transfer path to the mold-receiving path. Each of at the mold cassette assemblies running within the track are configured to retain a mold assembly, wherein the mold cassette assemblies are configured to move along the track between a retracted position spaced from the mold-receiving path adjacent to the concrete products forming machine, and position(s) intersecting the mold-receiving path including an incoming mold cassette position, and an outgoing mold cassette position.
