Patent number: 11919201Abstract: The invention relates to a method and a processing plant (1) for plastic material, for the recycling thereof. To this end, the processing plant (1) comprises a feed device (4), a processing unit (2) having a comminuting device (5) and a conveying device (6) adjoining the comminuting device (5), and an extrusion device (3) having an extruder screw (21). During its conveying movement along a first conveying section (9) toward a transfer region (8) by means of the conveying device (6), the comminuted plastic material is heated to a transfer temperature with a mean temperature value, which falls into the range of the softening temperature of the plastic material. In the transfer region (8), the comminuted plastic material is transferred to the extrusion device (3).Type: GrantFiled: December 6, 2019Date of Patent: March 5, 2024Assignee: Next Generation Recyclingmaschinen GmbHInventor: Guenter Kroiss

Patent number: 11472064Abstract: A method for producing a polycondensate melt from a primary material and a secondary material from materials of substantially the same type is provided. A first partial melt stream of the primary material and a second partial melt stream of the secondary material are provided, and a measured value of the intrinsic viscosity of both partial melt streams is determined, and a difference value is calculated from the measured values. Based on the difference value, the intrinsic viscosity of the second partial melt stream is increased, reduced or maintained unchangedly by using a first melt treatment device. Subsequently, the two partial melt streams are combined into a common melt stream.Type: GrantFiled: July 2, 2019Date of Patent: October 18, 2022Assignee: NEXT GENERATION RECYCLINGMASCHINEN GMBHInventor: Thomas Pichler

Publication number: 20210213645Abstract: The invention relates to a method for producing a polycondensate melt from a primary material and a secondary material from materials of substantially the same type. A first partial melt stream (I) of the primary material and a second partial melt stream (II) of the secondary material are provided, and a measured value of the intrinsic viscosity of both partial melt streams (I, II) is determined, and a difference value is calculated from said measured values. Based on said difference value, the intrinsic viscosity of the second partial melt stream (II) is increased, reduced or maintained unchangedly by means of a first melt treatment device (8). Subsequently, the two partial melt streams (I, II) are combined into a common melt stream.Type: ApplicationFiled: July 2, 2019Publication date: July 15, 2021Applicant: Next Generation Recyclingmaschinen GmbHInventor: Thomas PICHLER

DEVICE AND METHOD FOR PROCESSING THERMOPLASTIC PLASTIC HAVING A BLOWING DEVICE FOR A CONVEYING SCREW
Publication number: 20180257268Abstract: A device (1a . . . 1i) for processing thermoplastic plastic is described, comprising a storage container (2) for receiving pieces of plastic particles or a conveying line (14) for conveying the pieces of plastic particles, and a conveying screw (3) following the storage container (2)/the conveying line (14) at a transfer opening (A). The device (1a . . . 1i) also comprises an extruder (4) following the conveying screw (3) and an air outlet (7) arranged opposite the transfer opening (A) and directed at this opening. A method for operating the device (1a . . . 1i) is also described, in which an air stream is aligned with the transfer opening (A). The strength and/or the direction of the air stream is adjusted or controlled as a function of a load on the extruder (4).Type: ApplicationFiled: September 21, 2016Publication date: September 13, 2018Applicant: Next Generation Recyclingmaschinen GmbHInventors: Klaus BRZEZOWSKY, Klemens GRUBER, Thomas PICHLER -

Patent number: 9908263Abstract: In a method and an apparatus for increasing the intrinsic viscosity of a polycondensate melt at negative pressure, the melt enters a chamber, in which a negative pressure of less than 20 mbar prevails, through a perforated plate or a screen having openings with a diameter of less than 0.5 mm. The melt passes through this chamber in free fall in thin threads and remains in a reservoir beneath the chamber for at least one minute. The melt is moved constantly in the reservoir, and discharged from the reservoir, by a helical mixing and discharge part.Type: GrantFiled: September 12, 2013Date of Patent: March 6, 2018Assignee: Next Generation Recyclingmaschinen GmbHInventors: Thomas Pichler, David Hehenberger, Helmut Behoun, Bernhard Pichler

Publication number: 20080175940Abstract: A device for reworking thermoplastic material has a milling unit for milling the plastic material and an extruder (5). The milling unit has a cylinder (1) with a supply opening and with a knife shaft and the extruder has an extruder screw (7) in a screw tube (6). The cylinder is connected to the screw tube of the extruder via a connecting opening (4). In order to prevent deposition of plastic material in the connecting opening, the connecting opening with reference to a plane (10) which lies in the axis of rotation (2) of the knife shaft and at a right angle to the axis of rotation (8) of the extruder screw is arranged asymmetrically viewed in the direction of rotation (11) of the knife shaft. In this way the wall thickness on the edge (12) of the connecting opening can be made much narrower; this minimizes this problem.Type: ApplicationFiled: October 30, 2007Publication date: July 24, 2008Applicant: NEXT GENERATION RECYCLINGMASCHINEN GMBHInventors: Gerold BARTH, Josef Hochreiter, Gunter Kroiss, Thomas Pichler, Walter Schmedler
