A machine tool with a chip evacuation device according to the present invention is provided with a cleaning mechanism for cleaning a part or the whole of the chip evacuation device and a control unit configured to control respective operations of the chip evacuation device and the cleaning mechanism in association with each other. By using an electric motor, such as a synchronous motor capable of position control, as a power source for the chip evacuation device, the respective operations of the chip evacuation device and the cleaning mechanism can be associated with each other to effectively clean the chip evacuation device.

An automatically cycling detecting-and-sorting device has a base, multiple accommodating elements, at least one pushing rod, multiple side rods, and a detector. An object under inspection is put in one of the accommodating elements, and the accommodating element is conveyed along a first channel of the base and is under detection of the detector. The accommodating element is conveyed to the discharging region and then conveyed back to the feeding region, or the accommodating element is pushed away and then conveyed back to the feeding region. Because each object under inspection is accommodated in an individual accommodating element, even though any object in the accommodating element fails to pass the detection, the disqualified accommodating element is pushed away individually without affecting the processing of other accommodating elements. The whole detecting, sorting and cycling proceed automatically.

A cleaning mechanism for use with a closed loop conveyor belt supported in continuous traversing fashion. The mechanism includes a housing for supporting the belt, a frame mounted to the housing proximate to the belt. A drive shaft extends between spaced apart locations of the frame and includes a pair of head sprockets adapted for supporting the belt at a selected location. A motor is engaged to an input end of the drive shaft. A counter weighted comb element is pivotally secured to the frame, an upper angled combed edge of the comb element arrayed in spatial non-contacting fashion with a traversing exterior of the belt for capturing elongated shaving debris suspended from the belt. A slave shaft extends between additional spaced apart location of the frame and which is rotated via a linkage with the drive shaft. Pluralities of bristles extend from the slave shaft in a cylindrical arrangement such that selected width extending portions of the bristles are arranged in successive contact with the belt upon rotation of the slave shaft in order to scrub the belt.

[Object] To provide a building material manufacturing apparatus that is suitable for suppressing clogging of a screen that screens a building raw material. [Solution] A building material manufacturing apparatus X1 includes at least a screen part 10 and a cleaning mechanism part 40. The screen part 10 includes at least one screen sheet 12 that has an inclination and that has a screen mesh. The cleaning mechanism part 40 includes a scraping part 40a. When the apparatus operates in a building material manufacturing mode in which a building raw material M is supplied to the screen sheet 12 and the screen sheet 12 is performing a wave motion, the scraping part 40a is separated from the screen sheet 12, and, when the apparatus operates in a cleaning mode in which the building raw material M is not supplied to the screen sheet 12 and the screen sheet 12 is not performing a wave motion, the scraping part 40a rotates in contact with the screen sheet 12.

A transfer device includes an extendable transfer platform. The transfer platform includes a fixed plate, a moveable plate, and at least one platform actuator configured to selectively move the moveable plate relative to the fixed plate between a retracted position and an extended position in which a leading edge of the moveable plate is located distally from a leading edge of the fixed plate. The transfer platform also includes a transfer belt having a first end secured to a first driven roller, and a second end secured to a second driven roller. The transfer device also includes a platform support structure secured to the transfer platform for supporting the transfer platform above a floor surface. The platform support structure includes at least one support actuator configured to selectively move the transfer platform relative to the floor surface between a lowered position and a raised position.
