摘要:
The invention relates to a belt run control device of a continuous belt (2) revolving over at least one cylindrical roller (1), wherein the rollers (1) are each designed as deflection rollers around which the belt (2) is wrapped, and wherein for the purpose of loading the belt (2) at least one cylindrical roller (1) is preloaded on both sides by means of elastic elements (3) designed to be equally acting for centering the belt (2) relative to the roller (1), and wherein a position measuring device is arranged in the region of the belt (2), wherein an adjustment element (5) that can be actuated by means of an pneumatic piston-cylinder unit (4) is arranged on at least one side of the roller (1). The belt run control device is characterized in that the adjustment element (5) is designed to apply a force that acts additively or subtractively in relation to the preloading force of at least one of the elastic elements (3).
摘要:
Eine Rundballenpresse umfasst einen Ballenpressraum (12), der von einem Pressmittel (30) in Form eines einzigen Pressriemens oder mehreren, mit ihren benachbarten Kanten direkt aneinander anliegenden Pressriemen (32) umgeben ist. Das Pressmittel (30) liegt an einer antreibbaren Walze (34, 54) und an frei mitlaufenden Walzen (38, 40, 42, 44, 36, 46, 48, 50, 52) an und wird durch seitliche Führungen (66, 74) in axialer Richtung wenigstens einer der Walzen (38, 40, 42, 44, 54, 36, 46, 48, 50, 52) seitlich geführt. Die seitlichen Führungen (66) sind bezüglich der beim Ballenbildungsbetrieb geltenden Bewegungsrichtung des Pressmittels (30) unmittelbar vor einer antreibbaren Walze (34) beidseits des Pressmittels (30) angeordnet. Sie bestehen aus in der Ebene des Pressmittels (30) rotierenden Scheiben (68) mit Nuten (76), in welche sich das Pressmittel (30) hinein erstreckt.
摘要:
A conveyor idler assembly (10) for supporting a conveyor belt (11) comprising a support frame (12) having at least one elongated linear or longitudinally curved support beam (16) which extends transversely of the conveyor belt (11) and at least one idler cassette (13) having an idler roller (30), the cassette (13) being mounted to the support beam (16) for slidable movement therealong.
摘要:
A conveyor belt aligning device (1) comprising a support frame (2) mounted on a support beam (3) and being substantially horizontal pivotable about a first axis (4), the support frame (2) comprising a frame formed by a cross member (6) and a lever arm (8) extending from the cross member (6); at least one conveyor belt support roller (10) mounted on the cross member (6) of the support frame (2); a guide roller (14, 15) mounted on a transverse beam that is pivotably mounted on the lever arm (8) of the support frame (2) , the transverse beam (16) being pivotable about a second axis (18), the guide roller (14, 15) being adapted to engage one of the longitudinal edges of the conveyor belt; a stay member (20) extending between the support beam (3) of the support frame (2) and the transverse beam (16) so that, in use, the transverse beam (16) remains substantially perpendicular with the centre line of the conveyor belt, whereby the conveyor belt, whereby the conveyor belt aligning device (1) further comprises means for adjusting the distance (19) between the first axis (14) of the support frame and the second axis (18) of the transverse beam (16), and means for adjusting the distance between the second axis (18) of the transverse beam (16) and a central axis (26) of rotation of the guide roller (14, 15).
摘要:
A belt conveying device (1) includes: at least three rollers (11,12,13), about which an endless belt (14) to convey an object, is entrained, including meandering correction roller (12) having a rotation shaft (12b), whose one end is fixed and another end is oscillatably supported; a belt detection sensor (16) provided adjacent to a side edge of the belt, which detects presence of the belt; and a belt skew controller which controls an oscillator to oscillate the meandering correction roller according to a preset control value in a predetermined range to correct skew. The oscillator moves a rotation center of a movable edge of the meandering correction roller along a tangential line of an ellipse having elliptical focuses corresponding to rotation centers of rotation shafts of the two rollers (11,13), other than the meandering correction roller, positioned respectively in upstream and downstream of and adjacent to the meandering correction roller in a belt conveyance direction.
摘要:
The treadmill is of the type which comprises: a chassis (10); an upper structure (20); a front roller (14) and a rear roller (15) that are horizontally journalled in said chassis (10), and an endless belt (30) mounted around the front roller (14) and rear roller (15) and presenting an upper path (31) and a lower path. The device comprises two optical sensor assemblies (40), each comprising an optical emitting means, disposed above or beneath the lower path of said endless belt (30), and an optical receiving means (42), disposed in the other of said positions, said optical sensor assemblies (40) operating between a belt aligned condition, interrupting the luminous flux from said optical emitting means to said optical receiving means (42), and a belt misaligned condition, in which said belt allows the optical flux between one of said optical emitting means and a respective optical receiving means (42) which is operatively associated with a visual and/or sonorous signalizing means (18) to activate said signalizing means (18) upon the misalignment of the belt (30).
摘要:
The invention concerns a device for automatic centring on a conveyor with belts supported by chain flexible rollers, comprising a central attachment receiving rollers with V-shaped angular orientation. Between the latter is arranged a rocking lever subjected to a displacement along a curved trajectory according to variation in altitude. The lever co-operates at its lower end with a fixing lug secured to a tensioning cable relative to the frame bearing the conveyor. The invention is characterised in that the rollers (20) of the central attachment are mounted in free rotation on their independent shaft (21) with V-shaped orientation, said shafts being detachably secured to an opposite end according to an angulation, by central linking means (22), secured to fastening means (23) for receiving and articulating the rocking lever (24), whereof the other end is secured to the fixing lug.
