Rotary compression-molding machine
A rotary compression-molding machine includes an upper punch-retaining portion disposed above a table including die bores and retaining an upper punch, a dust-proofing device including a sealing case including a bottom wall that includes an insertion bore penetrated by the upper punch and faces a downward surface of the upper punch-retaining portion, and an outer wall facing an outer surface of the upper punch-retaining portion, and supported by the upper punch-retaining portion, and an expandable dust cover attached to be in contact with a downward surface of the bottom wall of the sealing case and covering a circumferential edge of the insertion bore and an outer circumference of the upper punch, and air passages disposed between the outer wall of the sealing case and the outer surface of the upper punch-retaining portion.
Gate for a tablet discharge of a tablet press and method for actuating a gate
A tablet press comprises a gate that defines a first switching position that feeds tablets into a first tablet outlet and at least a second switching position that feeds tablets into at least one second tablet outlet. The table press further comprises a control apparatus and a drive apparatus. The drive apparatus is configured to be actuated by the control apparatus to move the gate from a home position defined as one of the first switching position and the at least a second switching position into a target position defined as a switching position that is not the home position. The gate is moved from the home switching position at a speed of movement toward the target position such that the speed of movement of the gate is reduced before the target position is reached.
SYSTEM FOR CONTINUOUSLY PROCESSING PULVERULENT PRODUCTS
A system for continuously processing pulverulent products includes at least two system inlets for pulverulent products. A mixer is provided that continuously mixes the pulverulent products received at a mixer inlet into a product mixture that is dispensed at a mixer outlet. A production machine having a filling apparatus continuously processes the product mixture from the mixer outlet into end products dispensed at the machine outlet. A conveyor apparatus conveys the product mixture from the mixer outlet to the machine inlet. The conveyor apparatus includes a first fill level sensor that measures a product mixture fill level in the filling apparatus of the production machine and a second fill level measures a product mixture fill level in a conveyor reservoir. A control apparatus receives measurement data from the first fill level sensor and the second fill level sensor and controls at least one production parameter based on the measurement data.
MEDICAL TABLET, AND MANUFACTURING METHOD AND MANUFACTURING APPARATUS FOR MEDICAL TABLET
An object is to provide a tablet manufacturing apparatus capable of supplying an IC chip to a desired position of pharmaceutical powder with a high accuracy and suppressing a positional displacement. The IC chip is supported by a positioning guide with a chip main body in a downward manner, and is held in a state of being positioned above pharmaceutical powder filled in a die hole before compression. The IC chip is supplied by a pusher.

FILING APPARATUS FOR A ROTARY PRESS
A filling apparatus comprises a filling material reservoir and a filling chamber that is connected to the filling material reservoir with a filling opening configured to dispense filling material into cavities in the rotary press. A first rotatably driven stirrer blade wheel with one or more stirrer blades and a second rotatably driven stirrer blade wheel with one or more stirrer blades are arranged in the filling chamber. The first rotatably driven stirrer blade wheel has at least one of a different geometry, a different direction of rotation, or a different rotary speed, than the second rotatably driven stirrer blade wheel.

Rotary press
A rotary press comprises a press frame and a rotor arranged thereon. The rotor has a die plate, an upper punch receiver receiving upper punches, a lower punch receiver receiving lower punches, an upper cam that guides the upper punches, and a lower cam that guides the lower punches. A rotor drive can drive the rotor rotationally. Within at least one dosing station, material is filled into receivers of the die plate for pressing. An upper pressing station has an upper pressing roller and a lower pressing station has a lower pressing roller. Coupling means couples at least one drive that operates the rotary press to the rotor such that, with movement of the at least one drive, the rotor is raised out of its operating position and into a removal position where the rotor can be removed out of the press frame in a lateral direction.

Compression punch for a rotary press
A compression punch for a rotary press, with a shaft, a punch head disposed at one shaft end and a compression zone disposed at the other shaft end, wherein the punch head features an upper mirror surface, an outer cylinder surface and a curved transition zone between the mirror surface and the cylinder surface, wherein the mirror surface and the transition zone form a three-dimensional surface, whose course in at least one radial direction can be described by a mathematical function whose second derivative is continuous.
