The invention relates to a device ","

for opening fiber bales, of which the fiber material ^from fiber bales

across the entire width of the support side of the

is plucked in layers from a web of bale moving back and forth.

In this known device, the procedure is that the bale, with one long side on one Lath table is transported over one or more rollers, which have striking pins, by means of

which the fibers are plucked out of the bale, whereupon they end up in a collecting container.
As the fibers decrease in a constant direction, there is a risk that a certain ~ - ~

Fiber pressing takes place in the horizontal direction, which »

favors the later formation of nits. In addition, 15

the many fibers caused by the impact of the pins is shown schematically in the drawing, and

torn. _although shows

To avoid these disadvantages, the invention consists of Fig. 1 is a schematic side view of a projection in that in the web provided with rollers direction to open fiber bales with in floor level Plucking fingers are arranged, which consist of support rollers arranged opposite one another;

overlying springs exist, driven in opposite directions- Fig. 2 shows an enlarged view of a transverse notch, closed when piercing the bale and cut through the plucking fingers and their drive to release the plucked amount of fiber again;

open in season. Fig. 3 illustrates the drive of the Zupffmger

The plucking fingers are preferably made of leaf 25 in the machine frame of the device, partly in springs, which sees guided on opposing curved paths and partly in section.

and distributed over the width of the runway and under the machine frame of the device are in a

half of a grating are arranged, which is stored in the plane support rollers or rollers 40, the Slideway of the machine frame is located; the plucking fingers form a runway. Between two support rollers pierce from below through the openings of the 30 40 the grating 42 is arranged. The total length Grating through when the bale escapes over the sliding tracks on both sides of the grating 42 to be led. speaks about twice the length of a fiber ball,

The leaf springs are on the machine width on the, as indicated in Fig. 1 by a double arrow, two rods lying parallel to each other are attached, alternately pushed back and forth on the runway the ends of which are each one with a coupling cam gear 35. Here the bale overflows between two have connected coupling rod, the grating 42 on its support rollers 40, which is on the upper end with the rocker and at its lower whole machine width is enough. Under the grating The ends connected to a crank disk of the transmission are composed of leaf springs 43 driven in opposite directions den, the two on each side of the runway 44 and 44 existing plucking fingers arranged with crank disks located in opposite directions are driven 40 their free ends through the openings 45 of the Git. The drive of the opposed crank disks terrostes 42 can pass. The leaf springs takes place by means of an infinitely variable V-belt - 43 and 44 are attached to rods 46 and 47 for this purpose, instinct. the ends of which each have a coupling cam gear

The slideway for the bales consists of coupling rods 48 connected on both sides 48, 50, 52 or 49, 51, 53 of the grating arranged and driven Auf- 45 or 49, which at its upper end with bearing rollers in small spaces in the rocker 50 or 51 and at its lower end Machine frame and are stored approximately at floor level. ver-Die with the crank disk 52 or 53 of the transmission Surface of the support rollers can be bound with one. The coupling rods 48 and 49 are respectively Toothing, striking pins or the like. Be provided. On each side of the machine on two counter-rotating rollers crank disks 52 and 53 are articulated individually or in groups with an indication 50. The free drive provided. The driven idler rollers are ends of the rockers 50 and 51 is suitable

through roller conveyors for taking up a bale supply
extended for changing mixture components.
An embodiment of the subject matter of the invention

The fact that the cross bars 46 and 47 with the springs 43 and 44 serving as plucking fingers are attached to the long ones Coupling rods 48 and 49 of the coupling cam mechanism are connected, is driven by the crank disks 52 and 53 given the opposing pair of plucking fingers a movement in which the The tips of the plucking fingers describe a kidney-shaped coupling curve, which is indicated by dashed lines in FIG is. The tips of the plucking fingers working in opposite directions pierce through the spaces between the grating 42 from below into the bale and pluck one with its positively controlled closing movement Flock of fibers out of the bale as the neighboring fibers are held back by the grating 42. It is therefore ruled out that a fiber layer extending over the entire width of the machine is by means of the picking finger is lifted. Rather, each pair of plucking fingers holds the plucked fiber flock on the ground the clamping between the resilient rockers 50 and 51 and guides the flake up to that shown in FIG. 2 specified curve intersection 6 *. Do the picking fingertips When this point is reached, the picking fingers open due to the control of the coupling cam gear 48, 50, 52 and 49, 51, 53 and release the fiber flock that passes through the filling shaft-like Essay 56 falls on the collecting conveyor belt 10, which forms the lower end of the essay 56, in which the plucking fingers are.

As FIG. 2 shows, the support rollers 40 are arranged at a small distance from one another. she are inevitably driven with a single or collective drive, whereby the control takes place in such a way, that the fiber bale is conveyed back and forth over the grating 42. The support rollers are for this purpose 40 ■ with pins not shown in the drawing or a suitable toothing occupied by impurities from the fiber layer to be plucked when the bale is transported back and forth that fall through between the nips. This way, impurities become removed from the fiber ball. The removal of the impurities is done by moving back and forth Guiding the bale and still promoted by the profiled surface of the rollers 40.

To the runways, which consist of driven and spaced bearing rollers 40, are followed by other roller conveyors that can hold a supply of bales in order to transfer them to the Support rollers 40 to slide when the fiber assortment changed or colored hybrid components should be added.

A larger number of such plucking finger openers are connected to one another in a modular manner united, and the collecting conveyor belt 10 then passes through all openers to the plucked fibers one to be fed to another spinning preparation machine. The combination of several machine frames this opener according to the figures in such a way that the runways are adjacent to each other not shown in the drawing. However, the collecting conveyor belt 10 runs through the entire system perpendicular to the direction of movement of the bales.

According to the invention, the advantage is achieved that by plucking the fibers, the bale advance and the easy possibility of varying the proportion of the mixture components, even with the bale opener extensive pre-cleaning and intensive mixing of the fiber material is made possible. The plucked. fingers also loosen fiber flocks from very hard-pressed fiber balls, whereby the plucking process creates a extensive fiber loosening takes place so that nep formation is largely prevented and also Fibers are not torn.

The pairs of plucking fingers distributed across the width of the machine are determined by spring strength, spring length and finger spacing adapted to the proportions of the fiber material. The grating 42 is designed accordingly.

ίο The drive shown for example with a Infinitely variable V-belt transmission can also be replaced by other drives. Is essential only that the picking finger pairs by means of a coupling cam gear or the like. The curved movement is issued, which enables a safe plucking of individual flakes and their release.

With a device according to the invention, cotton balls can be plucked, in which the simultaneous removal of the impurities

ao gen has a particularly beneficial effect. However, it is also possible to use balls of artificial fibers such as rayon or to pluck up other fiber balls. The arrangement of the slide and roller tracks at floor level allows the bales to be pushed open

as these tracks and any change of fibers, to bring about fiber blends. It is sufficient to select the desired bales from the bales in stock To push the type of fiber over the roller or slideway.
