A bale opening machine is provided with a safety apparatus, by means of which there are produced safety barriers or fences parallel to lengthwise sides of a row of bales to be opened and/or substantially perpendicular to the direction of movement of the bale opening machine. The safety apparatus moves in conjunction with the bale opening machine. The safety apparatus can comprise mechanical and/or sensory protective structure. The sensory protective structure comprises one or more electro-acoustical transducers arranged in a sonic chute together with one or more reference reflectors such that transmitted acoustical signals are split into a measuring signal and a reference signal. The reference signal is reflected at one of the reference reflectors, whereas the measuring signal is reflected at a deflection reflector into the monitored area and back again by an object located in the monitored area.

Safety apparatus for a traveling unit of a textile machine and method of

A method for enabling the cleaning of fibers in a fiber cleaning machine in which a cleaning stream moves tufts around a rotating cleaning cylinder, the tufts being cleaned and opened. The cleaning action can be adapted to fibers of varying origin and to an increasing degree of opening in the course of cleaning. The cleaning stream is, to a large extent, controlled and controllable by decoupling it from the dynamic behavior of the transport streams which transport material to and away from the cleaning process. Compensation for variations in the cleaning stream, and in the material supplied for cleaning, are achieved by control of the cleaning intensity, in order that the tufts emerging from the cleaning process are constant and optimally cleaned and opened. The invention concerns also suitable fiber cleaning apparatus for the realization of the described method. The apparatus includes a cleaning cylinder positioned in a casing and a plurality of cleaning elements extending from the cylinder. The length, shape and density of the elements can change along the length of the cleaning cylinder so that the cleaning intensity varies along the length of the cylinder. Adjustable grid bars can be positioned below the cleaning cylinder.

Adjustable cleaning of fibers in a spiralled air path and apparatus

A bale removal machine having sensory control protective apparatus and a process for the sensory control of the protective apparatus. During at least an initial pass of the bale removal machine along a row of bales, at least one control sensor scans and monitors an area located in the feed direction of the removal member of the machine. If the evaluating unit connected to the control sensors detects a bale, the protective curtains are deactivated immediately before a bale is detected by same. In subsequent removal passes, the protective curtains are activated and deactivated as a function of the known bale profile and/or the control sensor or sensors. If presence of a foreign object, particularly a person, is detected, protective measures are initiated by the protective curtains.

Bale removal machine with sensory control protective mechanism

A method and an apparatus for operating a bale opening machine having an opening member, wherein the height profile of a row of bales is determined by at least one sensor directed towards the bale surface and is used to control the position of the opening member during the subsequent bale opening. The received signal of the sensor, which is preferably an optical or acoustical sensor or a sensor which operates with radar waves, is processed to obtain a signal corresponding to the hardness of the bales. In addition, the in-feed and, optionally, the penetration of the opening member, is controlled or regulated in accordance with the hardness signal. Various slip-free length measuring devices serve to determine the longitudinal position of the opening member along the row of bales.

Distance of travel measuring device for use with a bale opening machine

A discharge device for discharging the waste from a fiber cleaning machine having a collecting basin and a blowing or sucking device. The discharge device has a collecting basin which is funnel shaped with a motor driven paddle wheel in the tapered part. The waste removal is controlled on the basis of weight indicating and/or filling level indicating sensors which are assigned to the collecting basin.

Method and apparatus for operating a bale opening machine

A method for the discharge of the waste from a fiber cleaning machine with the retention of the operating pressure difference to the surroundings of the machine. The waste inside the machine is collected to a predetermined filling level and after this filling level has beeen reached only a predetermined part of the waste is removed so that the part of the waste which is not removed can be effective as a sluice layer. A discharge device for discharging the waste from a fiber cleaning machine having a collecting basin and a blowing or sucking device. The discharge device has a collecting basin which is funnel shaped with a motor driven paddle wheel in the tapered part. The waste removal is controlled on the basis of weight indicating and/or filling level indicating sensors which are assigned to the collecting basin.
