Patent number: 11697557Abstract: The invention relates to idler diagnosis systems on conveyors, comprising a rail system as a track for suitable running gears and the running gear, the rail system being formed from a closed profile or tube. The rail system comprises a multi-part track holder arranged on the belt frame, a fixing rod and a running rail, the track holder being suitable for accommodating the running rail at at least one end by insertion, thus creating a track without cross-section differences. The running gear has at least one two-roller system as a guide and drive system, and at least one chassis that accommodates and connects the two roller systems and has connection options for sensor-system carriers and/or energy control module. The guide system encloses the track so only one movement (forwards/backwards) along the track is provided. The drive system moves the chassis and all the connected systems with respect to the track.Type: GrantFiled: April 22, 2021Date of Patent: July 11, 2023Assignee: TAKRAF GmbHInventors: Rainer Kahrger, Jan Nowak, Boris Freier, Mario Dilefeld

Patent number: 10926957Abstract: A method and a device are provided for replacing individual idler rollers for conveyors, with which a web belt can be lifted and worn-out or damaged idler rollers in upper and lower runs can be individually replaced. The device includes, separately for replacing the idler rollers in the upper run and in the lower run, a subframe (1) for lifting the web belt (7) and for holding the web belt (7), such that a sufficient clearance is formed for replacing worn-out idler rollers (53) by means of a changing frame (2). A service vehicle is equipped with a lifting apparatus for moving dividing devices. The process steps include lifting the web belt (7), removing the old idler roller (53old), inserting the new idler roller (53new) and lowering the web belt (7). The drawing shows the use of two dividing devices in the replacing of idler rollers in the upper run.Type: GrantFiled: August 8, 2018Date of Patent: February 23, 2021Assignee: TAKRAF GmbHInventors: Rainer Kahrger, Mario Dilefeld, Steffen Vollrath

Patent number: 10486910Abstract: The present invention relates to a conveyor belt system with a circulating conveyor belt, in which a loadable conveyor belt segment rests on upper rolls and an unloaded conveyor belt segment rests on lower rolls, and in which an enclosure extending along the longitudinal axis of the conveyor belt system. The invention also relates to a system for monitoring the rolls in this conveyor belt system. A task of the invention is to propose a conveyor belt system in which the detection of defective rolls is facilitated. The task is solved by way of a conveyor belt system in which the enclosure features diagnostic windows on at least one side of the conveyor belt, such that the diagnostic windows are arranged at the level of the rolls of the conveyor belt and are designed for optical and/or acoustic monitoring of the bearings of the rolls, by being either transparent to diagnostic signals, or easily openable.Type: GrantFiled: May 31, 2018Date of Patent: November 26, 2019Assignee: TAKRAF GmbHInventors: Rainer Kahrger, Mario Dilefeld, Jan Nowak

Patent number: 9469478Abstract: A wall (2), for receiving one or more wear plates (1), has openings for receiving at least some of the fastening elements (11, 12) of the wear plates (1). The wall has, furthermore, gaps (22), with dimensions corresponding to the width and thickness of the wear plates (1). Slots (23) extend from the gaps (22). The slots (23) correspond to the fastening elements (11, 12) of the wear plate (1). The fastening elements (11, 12) of the wear plates (1) can pass through the wall (2), through the slots (23).Type: GrantFiled: May 14, 2015Date of Patent: October 18, 2016Assignee: TAKRAF GmbHInventors: Rainer Kahrger, Mario Dilefeld, Carlos Llanos

Patent number: 9333976Abstract: A track displaceable service vehicle replaces individual worn or damaged idlers with new idlers in the upper run and lower run of a belt conveyor with rising or falling conveying route, in which there is little space for the use of the service vehicle for replacing the idlers. The service vehicle accommodates a magazine for new and worn idlers and auxiliary devices for lifting the belt and removing old and for installing new idlers. A platform carries service personnel, and can be brought into a horizontal position in case of an inclined travel route of the service vehicle. The replacing of worn or defective idlers takes place in certain cycles in which the entire segment of the belt conveyor is removed and all worn and defective idlers are replaced. The service vehicle has a drive and is suitable for long tunnel sections (conveying routes which extend over several kilometers).Type: GrantFiled: July 29, 2014Date of Patent: May 10, 2016Assignee: TAKRAF GmbHInventors: Rainer Kahrger, Mario Dilefeld, Steffen Vollrath
