Definitions
- the present invention relates to a bale plucking machine for plucking fibres from the bales arranged on both sides of the machine.
- a fibre plucking machine is used to pluck fibres from a stock of bales that are arranged on both sides of the machine.
- the conventional plucking machine comprises a trolley and a turntable mounted thereon.
- a plucking head assembly is attached to the turntable through a tower which is mounted on the turntable.
- the plucking head assembly consists of one or more plucking rollers, a suction arrangement and a grill arrangement.
- a locking spindle is housed inside the tower on which the plucking head assembly slide in a vertical direction.
- the plucking rollers have a plurality of plucking teeth disposed on the outer surface thereof to pick up the fibres when the plucking head travels on and above the stock of the fibre bales.
- the plucking teeth forms an integral part of the roller and are fixed permanently therein by welding or such other means.
- This arrangement is found disadvantageous as failure of a single tooth in the assembly necessitates replacement of the entire roller assembly.
- rollers with multiple segments were constructed where each rollers is divided into different segments and each segment is provided with fixed teeth thereon. These segments constitute the entire roller assembly. This avoids replacement of the entire roller in case of damage or failure of a single tooth as replacement of the damaged segment alone is sufficient. Replacement of segments is also expensive and the down time of the machinery during such replacement is considerably high resulting in production loss. Disassembly of the damaged roller involves removal of contact rollers and grills which are heavy components leading to high labour.
- the grill is disposed beneath the plucking rollers wherein the width of the grill spacing has direct impact on the inlet of fibre and tuft formation. Therefore, the higher inflow of fibre lead to high tuft formation and lower inflow of fibre improves fibre quality. This is a factor for fibre processing industry to desirably select between high production with a compromise on tuft formation and to select reduced production for achieving high quality of fibre.
- Known methods are available for increasing the inflow of fibre material by either lowering or lifting the plucking rollers or by swivelling the plucking rollers desirably. These methods involve complicated mechanisms and driving elements for enabling such movement or swivel of the plucking rollers.
- Conventional suction arrangement of the plucking head assembly consists of suction means, suction hood and collection system.
- Suction hood in the hitherto known suction arrangement is permanently bonded to the plucking head assembly.
- Such permanent bonding is found disadvantageous as it prevents easy access for cleaning and maintenance of the components housed within the head assembly.
- Contact rollers and the grill are to be dismantled to provide access for cleaning and maintenance of the conventional plucking machine.
- the plucking head assembly is lifted and lowered by a drive system in which a drive medium such as a chain is connected to the head assembly.
- a drive medium such as a chain
- the other end of the chain is provided with counter weights for safety reasons.
- the turntable arrangement which is widely used in conventional plucking machines for turning the head assembly from one side of the machine to the opposite side includes complicated gear drive systems. These gears frequently get affected by fibre flies and fibre as they get stuck to grease present in the gears. Further, the gears require high momentum for rotation and are not easily accessible. In addition the known gear drive system is expensive and requires frequent maintenance.
- the plucking head assembly is enabled to travel horizontally on a semicircular path in order to turn from one side of the machine to the other side of the machine for plucking fibre bales.
- one end of the spindle is inserted into a locking hole provided on the side of the trolley. The plucking head gets locked when the spindle is inserted into the locking hole in the trolley.
- the spindle is lifted from the locking hole, and the turntable, which is now free to rotate, is rotated together with the spindle and the head assembly to the other side of the machine till the free end of the spindle is inserted into the locking hole on the opposite side of the trolley.
- the insertion and the removal of the spindle in the locking holes are enabled by a separate spindle drive arrangement comprising of expensive and complicated driving means such as a motor which involves cost and frequent maintenance. Disclosure of the Invention

- the plucking head assembly of the bale plucking machine of the present invention includes plucking rollers provided with detachable strips of plurality of teeth on its periphery. Strips with damaged teeth may easily be detached from the roller and can be replaced with a suitable strip in good condition with minimum downtime. Removal of the entire roller or a roller segment is thereby avoided.
- the strips may be of any desired length such that more than one strip may be fixed to form a single row of teeth. Strips may be fastened to the roller with the help of threaded insertion.
- the interchangeable grill assembly of the plucking haed assembly consists of two longitudinal frame members between which a plurality of grill bars are provided.
- the grill bars are shaped so as to allow two plucking rollers to rotate in the opposite direction with respect to each other Bars are shaped such that the plurality of teeth
- the grill assembly consists of guiding means like shackles preferably made of stainless steel to guide the fibre material m the grill bars.
- the spacing of grill bars in one grill may be different from the spacing in another grill. For instance, spacing between bars in one grill assembly may be 60mm while in another assembly, the spacing may be 120mm.
- These grill assemblies may be fixed to the plucking head with the help of fasteners. Depending upon the quality of fibre to be produced and the desired production rate, these grill assemblies may be interchanged easily.
- the suction hood of the plucking head assembly is made detachable providing easy access to areas located on or above the plucking rollers and inside the plucking head assembly once the suction hood is detached from the head assembly.

- the driving medium consists of a pair of slings.
- the drive system consists of a pair of rollers, a shaft connecting the rollers, and a motor.
- the drive system is housed inside the plucking head assembly.
- One end of each of the slings are fixed to the tower and the other end is fixed to the head assembly through the rollers of the drive system.
- the rollers are connected by the shaft which is driven by the motor. When the motor is driven the slings gets wound or unwound on said rollers thereby lifting or lowering the head assembly as desired.
- the drive system for rotating the turntable includes a driving means, driving medium and a guiding roller.
- the driving medium transfers the drive force from the driving means to the turntable.
- the guiding roller guides the driving medium to overlap more than half the circumference of the turntable so that the turntable is rotated in a semi-circular path on both, clockwise and anti-clockwise directions with lesser amount of force.
- the driving medium keeps the dust away and thereby reduces maintenance and also less downtime in case of replacement.
- the spring bias provided in the spindle enables the insertion of the spindle into the locking hole in the trolly so as to lock the plucking head assembly to a particular side of the machine.

- the shape of the suction hood is a major factor which enables free and smooth flow of materials. To obtain best results, the maximum height of the suction hood should be between 2 to 3 times, preferably 2.67 times, of the diameter of the plucking roller.
- reference numeral 5 indicates the tower of the fibre plucking machine, plurality of slings (11, 11') are fixedly mounted on the tower with the help of fixing means (12). Fixing means may be clamps or rivets. Plurality of rollers 15 are mounted on the head assembly through a shaft (14), the other end of each of the sling is rotatably wound on these rollers.
