摘要:
A fiber bale opening device (1.1) with a bale opening organ (30) moves in the direction of the arrow A over a row of bales (4) to open fiber flocks from the surface of the bales by means of the opening rollers 6a and 6b. The opening rollers are inclined in such a way that the bales are opened with an angle .gamma. to the horizontal. The opening rollers (6a and 6b) are moreover adjustable to incline in such a way that the depth of penetration (T.1) of the leading opening roller correspond substantially to half the penetration depth (T.2) of the trailing opening roller. These penetration depths can, on the one hand, be effected by the setting of the opening rollers. Movement of the opening organ (30) in direction (D) sets of the opening rollers in order to retain the opening depth (T.1).

Individual fiber components are blended in accordance with the properties of a required intermediate product such as a card sliver or an end product such as a yarn. The fiber bales are combined into component groups and the fiber components in the groups are accurately supplied by metering devices to a blender in which the components are uniformly mixed. The product from the blender may be cleaned and thereafter carded into a sliver. The characteristics of the sliver, such as the color, fiber, fineness and quantity, are tested and adjustments made in the blending in dependence upon any deviation from preset values for the characteristics.

The fiber flock removal apparatus has a pair of removal rolls which may be adjusted in height relative to each other to obtain different depths of penetration into the fiber bales. The removal rolls may rotate codirectionally with the direction of travel or may operate in contra-direction with respect to the direction of travel. The rolls may be mounted individually for vertical movement relative to each other or may be mounted in a common removal means which is pivotal about a horizontal axis to achieve adjustability in the relative heights of the removal rolls. In one embodiment, the rolls are maintained in a common horizontal plane while grid bars are angularly adjusted to obtain different depths of penetration of the removal rolls into the fiber bales.
摘要:
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.
摘要:
The flock delivery system employs a microcomputer with a storage cell for each marker and a storage cell for each stretch of path (containing one or more bale groups) between the markers. The control system is conditional selectively to "permit" or "inhibit" extraction of flocks from bales in each block individually. Various flock blending combinations can be obtained from time-to-time by programming of the control system.

A fiber bale opening machine having an inclined opening roller (1) is provided with conveying apparatus (100) for stepwise displacement of fiber bales in the direction of the opening roller. The roller is movable transversely with respect to the direction of the displacement. The conveying apparatus includes at least one stationary support for supporting the bale and at least one shifting device for performing a repetitive movement cycle starting from an initial position and returning back to it. In the initial position, the lifting device is lower than the stationary support and the bale is supported on such support. Later the lifting device moves up to take over support of the bale and during this time it shifts in the direction of intended bale displacement.
摘要:
The bearing unit comprises a plurality of bearing elements rotatable relative to each other. A shell encircles the plurality of bearing elements. A body of resiliently compressible material is located between the shell and the plurality of bearing elements and possesses a predetermined compressibility. This body of resiliently compressible material retains the plurality of bearing elements relative to the shell and permits free adjustment of the plurality of bearing elements relative to the shell within limits determined by the predetermined compressibility of the resiliently compressible material.
摘要:
The removal roll carrier can be inclined at an angle while the carrier is simultaneously moved vertically and while the removal apparatus moves over the line of fiber bales. This has the advantage that flocks can be removed from the bales not only in the horizontal direction but also in an inclined direction. A microprocessor controls the pivoting of the removal apparatus into a predetermined inclined position while simultaneously moving the removal apparatus vertically during movement of the machine frame along the path of the fiber bales.
摘要:
A method and apparatus for opening fiber bales including a fiber removal element, compression means disposed upstream of said fiber removal element and advancing means near said compression means to advance the surface layer fiber material of a bale toward said fiber removal element.
摘要:
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.
