Description

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a fiber bale disintegrating machine for disintegrating fibers from bale disposed on both sides of the machine.

BACKGROUND OF THE INVENTION

In the textile industry, fiber disintegrating machines are utilized for the purpose of disintegrating fibers from compressed bales arranged on both sides of the machine. Known opening machines include a carriage on which a rotary table is arranged. The disengagement head assembly is attached to the turntable by a tower mounted on the turntable. The opening head assembly consists of one or more opening rollers, a suction device and a grate assembly. Inside the tower there is a locking spindle on which the opening head is moved vertically.

The disintegrating rollers are provided with a plurality of disintegrating teeth disposed on their outer surface for plucking the fibers as the disintegrating head moves over the compressed fiber packages. In known disintegrating machines, these disintegrating teeth form an integral part of the disintegrating roller to which they are permanently attached.

by welding or other similar means. This arrangement is very disadvantageous since damage to a single tooth of the assembly necessarily requires replacement of the entire roller assembly.

In order to overcome the above drawback, rollers with multiple segments have been constructed, each roller being divided into different segments, and each segment having teeth attached thereto. These segments form an overall set of rollers. This eliminates the need to replace the entire roller in case of damage or loss of a single tooth, since it is sufficient to replace only the damaged segment. However, the replacement of the segments is also very expensive, and the shutdown time of the machinery during this replacement is very large, leading to significant production losses. Disassembling a damaged roller involves removing the contact rollers and grates, which are very heavy parts, so disassembly is very labor intensive.

In the known fiber bale opening machines, the grate is located below the opening rollers, the width of the space between the grate bars having a direct impact on the fiber inlet and on the formation of tufts or lumps of fibers. As a result, a higher supply of fibers leads to a higher formation of tufts, while a lower supply of fibers leads to an increase in the quality of the fibers.

This factor requires the choice in the fiber processing industry to choose between high production volumes with compromise on tufts or low production volumes to achieve high fiber quality.

Generally known methods are available for increasing the supply of fibrous material either by lowering or lifting the opening rollers or by desirable turning the opening rollers. These methods include very complicated mechanisms and drive elements to allow such movement or rotation of the opening rollers.

Known suction devices for the opening head assembly consist of suction means, a suction hood and a collection system. The suction hood of such known suction devices is permanently attached to the opening head assembly. This permanent attachment is very disadvantageous because it prevents easy access for cleaning and maintenance purposes of the components housed in the disassembly head assembly. The contact rollers and grate must be disassembled to provide access for cleaning and maintenance on known disintegrating machines.

The distributor head assembly is lifted and lowered by a drive system in which a drive means, such as a chain, is connected to the distributor head assembly. The other end of this chain is provided with a counterweight for safety reasons. During operation, the drive rotates to allow the chain to move, further lifting and lowering the opening head assembly. The drive system of this known arrangement is housed in the tower of the opening machine, where it occupies a relatively large space.

The existing known system also requires the use of very costly and complex terminal boxes to drive and control the drive. In addition, chain drives very often require maintenance and cleaning and are susceptible

44 4 44 44 4444444 4 4 44 44 44 44 44 44 44 44 444 to slip. This slippage of the chain results in lowering of the opening head when it is not required, which can damage the machine parts. Known drive systems are also very susceptible to unexpected failures.

The rotary table arrangement, which is commonly and widely used in known disintegrating machines to rotate the disintegrating head assembly from one side of the machine to the other, contains very complex gear drive systems. These gears are very often influenced by flying fibers which are trapped in the lubricating grease with which the gears are lubricated. In addition, these gears require high torque and are not easily accessible. Furthermore, the known gear drive systems are very expensive and also require frequent maintenance.

In known opening machines, the opening head assembly can be moved horizontally along a semicircular path so that it can rotate from one side of the machine to the other for the purpose of opening the compressed fiber packages.

In order to block the opening head assembly, i.e. to ensure linear horizontal movement on one side of the machine and to prevent unexpected rolling back to the other side of the machine, one end of the spindle is inserted into a blocking hole formed on the side of the carriage. The spreader head is locked when the spindle is inserted into this locking hole in the carriage.

* · * * * * * * * * * * * *

5 · ··· ··························

As soon as the spreader head has finished loosening the fibers on one side of the machine, the spindle is lifted out of the locking hole, whereupon the turntable, which can now rotate freely, rotates with the spindle and spreader head assembly on the other side of the machine until the free end of the spindle engages hole on the opposite side of the truck.

In the known opening machines, the insertion of the spindle into the blocking holes and the removal of the spindle from these blocking holes is made possible by a separate spindle drive arrangement which contains expensive and complex driving means, such as an electric motor, requiring expensive and frequent maintenance.

························

Preferably, each belt consists of one or more segments, each segment having a row of teeth.

Preferably, the exchange grate comprises two longitudinally spaced frame members between which spaced-apart grate bars are spaced, said frame members having guide means for guiding the fiber stream into the space between said grate bars.

The distance between the grate bars is preferably about 60 mm.

The distance between the grate bars may also preferably be about 120 mm.

The disintegrating head assembly of the fiber bale disintegrating machine of the present invention includes disintegrating rollers provided with removable belts with a plurality of teeth at their periphery. Thus, belts with damaged teeth can be easily removed from the spreader roller and replaced with suitable undamaged belts during the minimum machine shutdown time. This eliminates the need to replace the entire opening roller or its segment.

The aforementioned bands may be of any desired length so that multiple bands may be fastened to form a single row of teeth. These strips can be attached to the opening roller by means of screw connections.

The interchangeable grate arrangement of the distribution head assembly consists of two longitudinal frame members between which a plurality of grate bars are arranged. These grate bars have

9999 99 99 9 such that the opening rollers can rotate relative to each other in the opposite direction. The grate bars are shaped in such a way that the teeth with which the opening rollers are provided do not interfere with one another.

The replaceable grate arrangement consists of guide means, such as stirrups, preferably made of stainless steel and intended to supply fibrous material to the grate bars. The distance of the grate bars in one grate may be different from the distance of the grate bars in another grate. For example, the distance between the grate bars may be 60 mm for one grid, while for another grid the distance may be 120 mm. The exchangeable grates can be attached to the opening head by means of fastening means.

Depending on the quality of the fibers and the desired production speed, the grate assemblies can be changed very easily. For example, if a grate with a large pitch between grate bars is mounted, the production rate is high, while when a grate with a small pitch between grate bars is used, the fiber feed is relatively small, resulting in a reduction in the production speed. The exchange of one grate for the other is done manually.

The suction hood of the opening head assembly is removable, thereby providing easy access to the spaces around or above the opening rollers and to the space inside the opening head assembly when the suction cover is removed from the opening head assembly. Consequently, the improved spreader head assembly of the fiber baler according to the present invention contributes to the present invention. ···· · · * minimizes labor intensive work and machine downtime, optimizing production.

The improved arrangement for lifting and lowering the opening head assembly comprises driving means and a driving system. The driving means consist of a pair of straps. The drive system consists of a pair of rollers, a shaft connecting the rollers, and an electric motor. The drive system is housed within the disassembly head assembly.

One end of each of the straps is attached to the tower, while the other end is attached to the opening head assembly via the rollers of the drive system. These rollers are connected by a shaft which is driven by an electric motor. When the electric motor is in operation, the straps are wound on or unwound from said rollers, resulting in the desired lifting or lowering of the opening head assembly.

The drive system for rotating the turntable comprises driving means, a driving medium and a guide roller. The driving medium transmits the driving force from the driving means to the turntable. The guide roller guides the drive medium to wrap more than half the circumference of the turntable so that the turntable rotates on a semicircular path both clockwise and counterclockwise, with little effort.

The propellant is dust-resistant, thus reducing maintenance costs, while also requiring only a short standstill time for replacement.
