Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a baler machine. More specifically, the present invention is a traveling type having a cotton opening device that moves forward and backward along a row of fiber bales, and at the time of performing the forward and backward movements, a fiber lump (fiber tuft) can be peeled off from the upper surface of the fiber bales. Regarding open bales. The opening device comprises a high speed rotating opening or stripping roller which is mounted horizontally in a downwardly open housing mounted on the tower of the baler. The housing projects cantilevered from the tower in a horizontal plane transverse to the running direction of the baler. As the height of the fiber bales decreases during the stripping operation of the fiber mass, the cantilevered housing and the cotton opener move cyclically downwards relative to the tower of the bales machine to open at least one opening. The cotton roller is constantly engaged with the surface of the fiber bales.

This application is a continuation-in-part of US application Ser. No. 07 / 570,877 filed August 22, 1990 in the United States.

The opening roller has a plurality of spikes or teeth (peeling elements) on its surface, and the plurality of peeling elements form a plurality of groups at intervals in the axial direction.
A plurality of stripping elements are circumferentially arranged within each group. Each group of stripping elements may be formed on the circumferential surface of a plurality of discs axially spaced from the axis of the unwinding roller. A grate may be arranged below the one or more opening rollers, which grate may be a plurality of grate bars oriented parallel to the running direction of the baler and spaced apart. It should be formed. A plurality of grid bars extending into the space between adjacent groups of stripping elements engage the upper surface of the fiber bales to keep the fiber bales stable.

[0004]

As the unwinding device moves along a plurality of fiber bales and the stripping operation proceeds, the gap between the groups of stripping elements of the unrolling roller causes the cotton bales to reach the upper surface of the fiber bales. Has a plurality of grooves and ridges formed alternately. It is difficult to remove such ridges because the stripping elements do not reach the ridges formed from the compressed fiber material. Rather, the fibrous material forming the plurality of ridges will be torn by being dragged by the fibrous material that directly engages the stripping element. The multiple ridges are only gradually removed during multiple passes of the bale machine.

During the stripping operation, in order to remove the ridges and grooves more quickly, a distance of at least one-half the axial center distance between adjacent groups of stripping elements is required. It is known to periodically move an opening roller relative to its housing in a horizontal plane and transverse to the running direction of the baler. When the grid is provided, the grid and the opening roller reciprocate integrally. Such a structure is disclosed, for example, in U.S. Pat. No. 4,281,437 issued August 4, 1981. In the above-mentioned prior art solution, a lateral axis movement mechanism in the horizontal plane of the opening roller with respect to its support housing must be provided. However, if a plurality of parallel opening cotton rollers are provided, the mechanism described above becomes particularly complicated.

It is an object of the present invention to groove from the upper surface of a fiber bales by changing the working path of the teeth of the opening roller by periodically moving at least one opening roller laterally in the horizontal plane. To provide an improved device for eliminating the. It is also an object of the present invention to further simplify the mechanism for providing lateral displacement movement in the horizontal plane.

[0007]

The object of the present invention is to provide a tower,
A cantilevered housing that is supported on the tower and projects laterally, and a cotton-opening roller that is rotatably supported by the cantilevered housing and is arranged in a horizontal plane in a direction transverse to the moving direction of the cotton-opening machine. A baling machine for running along a row of a plurality of fiber bales and peeling a fiber mass from the upper surface of the plurality of fiber bales, wherein the cantilever housing together with the cotton opening roller is in a horizontal plane. The present invention is achieved by a cotton opening machine, which is provided with a position changing means for moving the tower with respect to the tower in a direction transverse to the moving direction of the bag opening machine. That is, in the above-mentioned prior art device, the opening roller is mounted so as to be capable of reciprocating in the horizontal direction in the horizontal plane with respect to the housing. In the invention, this is done by moving the housing itself.

In a preferred embodiment of the invention, the motor is periodically started to move the housing, at least one unrolling roller and / or the grid integrally laterally in a horizontal plane relative to the tower. It Such movement is provided by a crank attached to the motor, i.e. during continuous operation, the crank is rotated a predetermined angle to alternately advance or retract the housing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A bale opener 1 is shown in FIGS. When the bale-opening machine 1 moves along a plurality of fiber bales arranged in rows, the bale-opening machine 1 strips the fiber mass from the upper surface of the fiber bales. The baler machine 1 has a carriage 3, and the carriage 3 has a plurality of wheels 4 traveling on rails 5 fixed to the floor.
The moving direction of the baler machine 1 is perpendicular to the plane of the drawing 1. A tower 6 arranged on the carriage 3 and moving integrally with the carriage 3 supports a cantilever housing 7 using a beam assembly generally designated by 8. The cantilevered housing 7, which is open at the lower side, has at its lower part two opening rollers or stripping rollers 9 supported in a horizontal direction perpendicular to the moving direction of the baler. When the open-bale machine moves on the rails 5 along the row of the fiber bales 2, a cotton-rolling roller 9 rotated at a high speed by a motor (not shown) peels the fiber mass from the upper surface of the fiber bales, and installs it on the cantilever housing 7. Throw it into the suction hood 10. A suction device (not shown) generates an air stream in the upstream direction in the suction hood 10, and carries out the stripped fiber mass from the opening device by the air stream. Since the height of the fiber bales decreases as the fiber mass is removed, the cantilevered housing 7 is periodically lowered relative to the tower 6 of the baler 1.

As shown in FIG. 3, each opening roller 9 has a shaft 9b, and a plurality of toothed discs 9c are fixed to the shaft 9b at intervals in the axial direction. In the space provided between the adjacent toothed disks 9c, the grid bar 11 is provided.

The magnitude of each position movement is 1/2 of the center-to-center distance a of two adjacent lattices,
That is, it preferably corresponds to 1/2 of the center-to-center distance b between two adjacent toothed discs 9c, and thus the plurality of ridges 2b formed during the previous work step or the plurality of previous work steps are scraped off. The upper surface of the fiber bales is smoothed. The horizontal position movement of the cantilevered housing 7 with the cotton swab roll 9 and the grid 11 takes place, for example, after a working step involving movement along each rail of the baler or after several working steps. Good.

The lateral horizontal displacement of the cantilevered housing 7 is an eccentric drive with an electric motor 12 mounted on a horizontal beam 13 which forms part of the beam assembly 8 and is held by the tower 6. It may be performed by an assembly. The cantilevered housing 7 includes the horizontal beams 13 and the vertical beams 14 and 15 forming a part of the beam assembly 8.
