Patent number: 5861180Abstract: In a powder feed apparatus and a control method thereof, a powder molding press feeds powder from a hopper of the powder feed apparatus to a feeder slidably disposed on a die plate of the press proper. Powder is charged into a die in the die plate. The feeder is electronically controlled to a correct position on the die. Powder is fed from a powder feed apparatus into a feeder slidably disposed on a die plate of a press proper and a feeder drive motor is servo-controlled by an output obtained by comparing detection outputs from a position detector for detecting the vertical position of the die plate of the press proper and a position detector for detecting the position of the feeder in its sliding direction. As a result, it is possible to avoid the trouble of changing cams or inserting insert cams every time the shape of the compact being molded changes. It is also possible to easily make changes to the movement speed of the feeder in correspondence with changes to the compact.Type: GrantFiled: April 25, 1996Date of Patent: January 19, 1999Assignee: Tamagawa Machinery Co., Ltd.Inventors: Hideo Kaneko, Kazutami Takahashi, Kiyoshi Ogawa

Patent number: 5713272Abstract: A powder press with mechanical-hydraulic shuttle control including a main press shaft, a control unit mounted on the powder press for converting rotational motion into translational motion, including a first actuator assembly; a second actuator assembly in fluid communication with the first actuator assembly; a shuttle assembly disposed at one end of the second actuator assembly; and a cardan shaft for transferring rotational motion of the main press shaft to the control unit. The control unit includes first and second shafts disposed in spaced relationship to each other; first and second wheels, each mounted on a respective one of the first and second shafts; a member interconnecting the first and second wheels in rotational engagement; and an adjustable cam member mounted on the second shaft and operatively engaging the first actuator assembly such that rotation of the main press shaft rotates the cardan shaft which, in turn, is coupled to the first shaft in the control unit.Type: GrantFiled: January 30, 1996Date of Patent: February 3, 1998Assignee: Dorst-Maschinen und Anlagenbay Otto Dorst und Dipl-Lng Walter Schegel GmbH & CoInventors: Hubert Schaidl, Walter Rau, Hartmut Waffenschmidt, Alfred Eisensehr

Patent number: 5629033Abstract: A machine for pressing earth into blocks has a rectangular breech and a press foot vertically reciprocally drivable in the breech. A bucking block is horizontally reciprocally drivable into and out of registration with an open upper end of the breech. Portions of the upper surface of the bucking block are tapered upwardly from front to rear and a horizontal bucking bar extends across the breech and bears downwardly against the tapered upper portions of the bucking block when the bucking block is in registration with the breech. The bucking bar can be supported at selectively variable levels above the breech and assures a firm positioning of the block against the force of the earth being compacted by the press foot. A rod extending vertically from and movable with the press foot cooperates with a sight line device fixed to the machine to facilitate visual determination of the elevation of the press foot within the breech.Type: GrantFiled: October 16, 1995Date of Patent: May 13, 1997Inventor: David Lienau

Patent number: 5573788Abstract: An improved dough divider is provided which has a measuring cup assembly for dividing a mass of dough into uniform smaller slugs. The apparatus is adjustable so that size of the dough slugs can be increased or decreased. The dough divider has a piston-cylinder arrangement for supplying a flow of dough. The measuring cup assembly has a cylindrical housing which has a central axis. A plunger aligned on the axis so that it can reciprocate axially within the housing. An elongated stud is threaded through the housing so that the stud is aligned axially with a stem of the plunger. The plunger slides in said housing when dough is pressed against the plunger face, such that the plunger stem can contact the stud to limit the sliding of the plunger.Type: GrantFiled: May 25, 1995Date of Patent: November 12, 1996Assignee: AM Manufacturing Company, Inc.Inventor: Thomas A. Atwood

Patent number: 5393218Abstract: Dough (10) should, in a volumetric sense, be measured in dough pieces, which during extended use, must very precisely take place. The improved measuring device can be built in dough dividers and gives, through the specific piston construction (3) with connected parts, an amazing result. In the sidewall of the piston an annular-shaped recess (20) is provided and in which a filter (21) is fitted. To the recess (20) a crosswise channel system (15) with a bore (16) is fitted, which is connected to a flexible suction/press hose (17).Type: GrantFiled: June 8, 1993Date of Patent: February 28, 1995Inventor: Lodewijk C. Rijkaart

Patent number: 5213816Abstract: A system for heating and feeding polymer coated powder to a heated die cavity of a compacting press. The system includes at least one heated vertical pipe for heating the polymer coated powder and for delivering the polymer coated powder by gravity from source thereof to the entry end of at least one horizontally oriented auger conveyor. The at least one auger conveyor is heated and imparts heat to the individual powder particles through a mixing action. The at least one auger conveyor delivers the polymer coated powder to the heated hopper of a shuttle assembly. The shuttle assembly is shiftable between a retracted position wherein the polymer coated powder is discharged from the shuttle hopper to a heated powder ring, to an extended position wherein the polymer coated powder is discharged from the powder ring to the heated die cavity of the compacting press. The system heats the individual particles of the polymer coated powder to a temperature just below the coagulation point thereof.Type: GrantFiled: May 31, 1991Date of Patent: May 25, 1993Assignee: Cincinnati IncorporatedInventors: Dale C. Smyth, Jr., Michael A. Halley

Patent number: 5182120Abstract: A device for dosing a plastic, perishable mass into moulds has a pressing chamber for receiving a dose of the mass from a feed vessel and a piston operable in the chamber to push and compress the dose into a mould. The device includes a valve for shutting off feed of the mass from the feed vessel and is particularly constructed to avoid spaces into which the mass can collect and spoil, while preventing reentry of the mass from the pressing chamber into the feed vessel.Type: GrantFiled: September 11, 1991Date of Patent: January 26, 1993Assignee: Stork Titan B.V.Inventors: Johannes K. O. Kusters, Joost A. W. H. Van Der Putten
