Definitions

  • the invention relates to a combing machine with a device for adjusting a distance between a nipper lip of a lower nipper plate and a lower detaching roller.
  • Combers have a nipper unit that swings back and forth, which presents the combed-out tuft to a subsequent pair of detaching cylinders for detaching, with the front end of the tuft being transferred to the clamping line of the detaching cylinders.
  • the tongs are in their front position and are open at the same time.
  • the fiber bundle pulled out of the wadding provided is pulled through a top comb at least with its rear end.
  • impurities still present in the fiber material (such as husk parts, but also neps) are retained and separated.
  • the tong unit in the machine described above is mounted on two swivel arms on each side.
  • the front swivel arm is mounted on the circular comb axis, while the respective rear swivel arm is non-rotatably attached to an intermittently driven tong shaft.
  • the tong shaft is driven by a vibrating hub, which is non-rotatably connected to the shaft via a clamping bush.
  • the intermittent movement of the tong shaft is effected by a connecting rod which is attached to the swinging hub and is mounted in a holder which is moved on a control disc.
  • a generic adjustment is in the DE 102 06 605 A1 disclosed.
  • a clamping connection between the pliers shaft and a clamping bush is released.
  • an existing locking device between the tongs shaft and the clamping bush must be loosened or readjusted.
  • This locking device can consist of a radially outwardly projecting rod fastened to the end face of the tongs shaft, in which there are spaced-apart adjusting screws which are clamped in the locking position against a lug fastened to the end face of the clamping bush.
  • the invention is therefore based on the object of proposing a combing machine with a device which eliminates the known disadvantages and enables simple and precise adjustment of the eccentricity at a predetermined position of the gear.
  • a combing machine with a machine frame, a drive unit, a gear and an operating device for displaying and entering values, and with a nipper unit pivotably mounted in the machine frame, which has a lower nipper plate with a nipper lip and an upper nipper plate, and with a pair of detaching rollers which forms a clamping line, wherein a drive arm of the tong unit is non-rotatably connected to an intermittently driven tong shaft and the tong shaft is driven via a clutch element which is connected to a driven gear element and an adjustment device connected to the tong shaft for setting a distance between the tong lip of the lower tong plate and the nip line.
  • a fixation of the gear in a basic position with a mechanical blocking and a sensor for measuring the distance or a variable proportional to the distance and a display of the distance on the operating device are provided.
  • the tong shaft is driven by an auxiliary tong shaft.
  • a drive wheel is non-rotatably attached to the auxiliary shaft of the tongs.
  • This drive wheel is set in continuous rotation by a gear element.
  • the transmission element can, for example, be a toothed wheel which meshes with the drive wheel of the auxiliary shaft of the tongs, or it can also be a toothed belt.
  • the auxiliary gripper shaft can be provided with a separate drive, which is linked in terms of control technology with other drives to form an electronic gear.
  • the tong shaft is set in an intermittent movement directly by its own drive. However, this drive is also only connected to the other drives of the combing machine sensible.
  • the continuously rotating auxiliary shaft of the tongs causes the tong shaft to move intermittently via a clutch element, so that the tong plate moves back and forth.
  • the coupling element consists of a cam disc mounted non-rotatably on the auxiliary pliers shaft, a cam roller resting against the cam disc, and a cam roller lever held non-rotatably on the pliers shaft, in which the cam roller is rotatably mounted.
  • Such drives are known from the prior art and are for example in the CH 714 580 A2 described.
  • the setting device required for setting the eccentricity is also known in various designs from the prior art; one possible design is that DE 102 06 605 A1 taken and described above.
  • the transmission can be fixed at various points, with the location of the use of a mechanical blocking depending on the design of the transmission.
  • a mechanical blocking has the advantage that a fixed position of the transmission element is detected by the blocking and the mechanical blocking, for example by a pin, holds the transmission in exactly this fixed position without play.
  • the transmission can be blocked via a transmission element of the transmission, such as the drive wheel of the auxiliary gripper shaft.
  • the gear mechanism is fixed by locking the cam disk. The freedom from play in the locking device is important because even a minimal play of a few hundredths of a millimeter contributes to inaccurate setting of the eccentricity. It is also advantageous if the gear mechanism is blocked as close as possible to the tong shaft, so that any play between the individual gear element elements does not have a negative effect on the accuracy of the setting of the eccentricity.
  • a sensor is also provided, which directly or indirectly measures the eccentricity or the distance between the gripper lip of the lower gripper plate and the clamping line of the pair of detaching rollers.
  • the sensor can be constructed as an optical sensor and detect the eccentricity directly.
  • a rotation angle sensor assigned to the tongs shaft would also have a size proportional to the distance Provide determination of the ecartement.
  • a preferred embodiment is the use of a simple distance sensor, for example of a capacitive or inductive design. Outside the drive unit, an eccentric is placed on the tong shaft, on which the distance sensor is radially aligned. A distance between the sensor and the eccentric now changes with the change of the radial position of the gun shaft.
  • the operating device used here can be rigidly attached to the comber.
  • a mobile device that can communicate with the controller of the combing machine is also to be understood as an operating device. All devices that have a display and an input field or, alternatively, a touchscreen are suitable for use as an operating device in the sense of the invention.
  • the degree of combing can be changed or an adaptation to the stack of fibers to be combed can be achieved.
  • the top comb needles should always have a predetermined, very small distance from the detaching cylinder in the front end position of the nipper unit, after adjusting the ecartement, the top comb holder must also be adjusted with respect to the lower nipper in order to set this predetermined distance again.
  • the basic position preferably corresponds to that position of the gearing in which the distance between the lip of the lower nipper plate and the clamping line of the pair of detaching rollers is the smallest.
  • the planned blocking exactly in this gear position mechanically into the designated gear element and locks any movement of the gear.
  • the fixing of the gear is advantageously designed as a locking lever.
  • a detent lever is a pin which engages in a depression or bore when it is moved, the engagement usually occurring under spring pressure. In order to get the latching lever out of the latched position, the latching lever must be moved out of the latched position against a spring force.
  • the spacing adjustment device is mounted behind a guard.
  • a protective device is provided to prevent unintentional handling and also to protect against contamination. Simple covers or doors are conceivable as protective devices, and the protective devices can be transparent. Doors of the machine or transmission housing can also be understood as protective devices. If housing doors are already provided at the relevant point at which the adjustment device is provided, no additional protective devices are necessary.
  • the size of the display of the distance on the operating device can be changed. This is particularly advantageous when the operating device is not installed in the immediate vicinity of the setting device. By switching the size of the display, the discount can be read without the operator having to move away from the setting device.
  • the operating device has an additional display in the area of the device for setting the distance.
  • the area of the device for adjusting the distance is to be understood as meaning the immediate surroundings of the device.
  • the additional display is arranged in such a way that the display can be easily read by staff who are making the adjustment.
  • the display can be attached at a suitable point in this area, with the building or installations or apparatus not belonging to the combing machine being a suitable place for attaching the additional display.
  • the display and/or the operating device is rotatably and/or displaceably attached to the combing machine or the sliver coiler, so that an optimal adjustment to the perspective of the operator can be achieved.
  • the display of the operating device advantageously changes automatically to a measured value display of the distance.
  • the display preferably automatically changes back to a state before the setting.
  • the work of the operating personnel is significantly accelerated by such a simple automatic system.
  • the same automatic switchover of the display can also relate to an additional display in the setting device, with this display switching on and off in each case.
  • the measurement of the distance can also be used during operation of the combing machine. Due to the back and forth movement of the tong shaft, the measured distance between the sensor and the eccentric moves within a specified range. If, due to a fault in the drive, in the gearbox or in the connection from the tong shaft to the tong plate, the tong shaft is displaced in its radial position compared to the setting, this can be registered by the sensor. It is also possible to define an area in which the comber must be switched off because there is a risk of a collision between the nipper lip and the top comb. By monitoring the distance in this way, damage can be avoided with the help of the sensor; the sensor is used as a crash sensor.
  • Fig.1 shows a schematic representation of a combing machine according to the prior art.
  • the combing machine comprises a machine frame 1, as well as a drive unit 2 and a sliver coiler 3.
  • the machine frame 1 is arranged between the drive unit 2 and the sliver coiler 3 and, according to the example shown, carries eight combing heads 4.
  • the combing heads 4 are connected to the drive unit 2 via drive shafts 5.
  • the individual components of the combing heads 4 are driven by a gear 6 arranged in the drive unit 2 .
  • a lap unwound from a lap roll 7 is combed out by the combing heads 4 and fed to a conveyor table 8 .
  • the combed-out fibers of the individual combing heads are brought together via the conveyor table 9 and fed to a drafting system 19 as a sliver 8 .
  • the sliver 8 is filled into a can 13 in the form of a loop via calender rollers 11 and a turntable 12 .
  • An operating device 14 with a display 15 is attached to the drive unit 2 , for example.
  • Fig.2 12 shows a tong unit 16 with a lower tong plate 17 and an upper tong plate 19 pivotably mounted on the lower tong plate 17.

  • the end 28 (tuft) protruding from the nipper unit 16 is then combed out by the circular comb segment 23 .
  • the tong unit 16 is inserted into the in 2 transferred forward position shown, in which it is open. In this position, a top comb 26 pierces the cotton end protruding beyond the pliers unit 16 .
  • the end of the wadding reaches a clamping line 25 of a subsequent pair of detaching rollers 24, where it is soldered to a nonwoven fabric 29.
  • the tong unit 16 in the in 2 The position shown is in a foremost position (front dead center), from which the rearward movement of the tong unit 16 then takes place.
  • the tong lip 28 of the lower tong plate 17 is at a distance d from the clamping line 25 of the pair of detaching rollers 24, which is generally referred to as an ecartement.
  • this distance d In order to determine the proportion of short fibers (noils) to be combed out, this distance d must be set accordingly. This setting is done by Change in the position of the angle of rotation, which is generated by the pincer shaft 33 during a comb game.
  • FIG 3 shows a partial view of the pliers shaft 33 in an area outside the gear 6 or the drive unit 2.
  • An eccentric 37 is applied to the pliers shaft 33 with its pliers shaft axis 34.
  • a distance sensor 38 is directed towards the eccentric 37 and measures the distance between itself and an outer surface of the eccentric 37.
  • An additional display 54 which is attached to the drive unit 2, is also shown as an example.
  • the additional display 54 is rotatably held on the drive unit 2 and displays the current value of the ecartment d. If the gripper shaft 33 is now rotated in its radial position about the gripper shaft axis 23 by the adjusting device, the distance between the outer surface of the eccentric 37 and the distance sensor 38 changes. This measured distance is proportional to the eccentricity d. By prior calibration of this proportionality, the eccentricity d is displayed directly on the additional display 54 during the adjustment process.
  • the nipper shaft 33 performs a reciprocating movement (arrow 56). This reciprocating movement takes place in a specific area of the compartment d known to the controller. By measuring the distance sensor 38, the controller can monitor whether the movement 54 of the tong shaft 33 is moving within this specified range or deviating from it. If there is a deviation, there is a risk of collision and the combing machine can be switched off by the control or a warning can be issued to the operator.
