Definitions

  • the invention relates to a device for the functionally correct positioning of an operating rotor which is movable along a spinning machine and is equipped with castors and which acts horizontally on at least one support roller on a support rail located on the spinning machine.
  • a flyer doffer that can be moved on the hall floor is known from the prior art, the chassis of which is individually height-adjustable in the manner of a three-point bearing (DE-OS 36 41 841). This doffer is leveled using built-in inclinometers.
  • operating runners which rest with two guide rollers on the spinning machine side on a guide rail arranged on the spinning machine (Japanese property rights Sho-60-67371, Sho-60-71725). On their side facing away from the spinning machine, these operating runners additionally have two rollers which roll on the hall floor and which can be adjusted in height by means of thrust piston gears. These height-adjustable castors can compensate for unevenness in the hall floor and thus prevent the operator runner from tilting.
  • the prior art also includes an operator runner, which rests on guide rollers on a guide rail arranged on the spinning machine (DE-AS 1 280 107).
  • guide rollers which have horizontal axes sen
  • guide rollers with vertical axes.
  • These guide rollers run on the front of the spinning machine. In order to relieve this spinning machine of the weight of the operator runner, these have spring-loaded undercarriage wheels.
  • the above-described operator runners have various disadvantages: the operator runners are either relatively complex in terms of their mechanical structure and therefore cost-intensive, or at least with a large part of their weight they rest on a guide rail arranged on the spinning machine.
  • the spinning machine frame is therefore disadvantageously significantly burdened by the weight of the operator, and must be dimensioned accordingly costly to exclude deformation.
  • the present invention is based on the object of designing a device of the type mentioned in such a way that on the one hand correct guidance of the operator with respect to the spinning machine to be supplied is ensured, especially with the exclusion of all transverse and longitudinal inclinations, but on the other hand the spinning machine frame should be burdened as little as possible.
  • At least one track roller runs on the side of the operating rotor facing the spinning machine in a guide rail arranged on the floor with respect to the spinning machine, and in that at least one roller can be raised and lowered via a drive device on the side facing away from the machine is. Due to the interaction of track rollers and the lifting and lowering rollers, which are actuated by a drive device, a precisely defined moment of force is continuously exerted during the operation of the operator, so that the support rollers are constantly pressed against the support rail without putting too much strain on it . This measure will beyond undesirable inclinations of the operator runner reliably avoided even on uneven hall floors without the spinning machine frame being subjected to unnecessary stress.
  • the support rail is attached to the wing seat of the flyer.
  • two support rollers can be mounted on a crossbar of the doffer above two rollers. This results in a good installation of the doffer compared to the flyer with exact positioning compared to this spinning machine with little technical effort.
  • two rollers can also be raised and lowered by a common drive device, a piston-cylinder unit, for example, serving as the drive device, the end regions of which are connected to the rollers via angle levers.
  • each roller can be raised and lowered by its own drive device.
  • Pneumatic, electrical, hydraulic or mechanical drive devices can be used.
  • the drive device In order for the drive device to function properly, it can be connected to at least one control unit. Furthermore, there is the possibility of automatic locking of the drive device when the support rollers arranged on the machine leave the support rollers. This prevents the operating runner, i.e. the doffer, from being tipped over by the drive device as a result of the support surface not being in contact with a support rail.
  • control unit can have a device which limits the contact pressure of the support roller to the support rail.
  • this device can be, for example, a pressure limiter; in the case of a mechanical drive device, an intermediate spring as a limitation for the spring travel.
  • a measuring element connected to the control unit can be used for the contact pressure of the support roller on the support rail. This ensures in a simple manner that the spinning machine frame does not experience a negative high load from the operator runner supported on it.
  • the doffer 2 here has at least one track roller 3 on the spinning machine side, which is guided on a guide rail 5 arranged on the hall floor 4.
  • This guide rail is aligned with respect to the flyer 1 and determines the working height of the doffer 2 and its distance from the flyer 1.
  • the guide rail 5 prevents inclinations of the doffer 2 with respect to its longitudinal axis.
  • a support rail 7 is fastened to the wing bench 6 of the flyer 1.
  • the doffer 1 is supported on this support rail 7 with at least one support roller 8.
  • This support roller 8 is attached to a crossbar 9 above the track roller 3.
  • the doffer 1 also has at least one roller 10 on its underside.
  • This roller 10 which is arranged on the side facing away from the spinning machine, can be driven via a drive mechanism 11, for example a thrust piston gear with a piston-cylinder unit or a spindle drive or other mechanical or pneumatic elements in the direction of hall floor 4.
  • the doffer 2 therefore has at least one track roller 3 on the side facing the spinning machine 1 in a guide rail arranged on the floor 4 and oriented on the spinning machine 1 and at least one roller 10 on the side facing away from the machine, which roller can be raised and lowered via a drive device 11 is.
  • the support rail 7 can be attached to the wing bench 6 of the flyer 1.
  • FIG. 3 Another construction is shown in Fig. 3: Here a support roller 8 and two track rollers 3 and 3 'and a roller 10 are used. This construction also ensures that the operator runner 2 runs smoothly along a spinning machine without any great stress on the spinning machine frame, with the exclusion of all transverse or longitudinal inclinations, regardless of the nature of the hall floor 4.
  • the two support rollers 8 and 8 ' can be raised and lowered by a common drive device 11.
  • the drive device 11 is designed as a piston-cylinder unit 12, the end regions 15 and 16 (piston rod) via angle levers 13 and 14 and pivot points 17 and 18 are connected to the rollers 10 and 10 '.
  • the piston-cylinder unit 12 is controlled via a control unit, which is not known and is not known per se.
  • this control unit can also have a contact pressure of the support roller 8 and 8 'to the support rail 7 limiting device.
  • Such a device can be designed, for example, as a pressure limiter or as a spring.
  • the control unit can be connected to a support member 7 with a measuring element, not shown, for controlling the contact pressure of the support roller 8 or 8 '.
  • the height adjustability of the rollers 10 is mechanically effected by a shaft 19 via a worm 20 and a worm wheel 21 which is seated on a threaded sleeve 22 which in turn is mounted on a bearing pin 23.
  • the roller 10 is supported against the threaded sleeve 22 by a spring 24.
  • the height of the roller 10 on the hall floor 4 can be adjusted by the interaction of the shaft 19 as well as the toothing and the threaded sleeve.
  • FIG. 7 The construction of this construction, which is shown schematically in FIG. 6, can be seen from FIG. 7: Two piston-cylinder units 25 and 26 are used as individual drive devices 11 ⁇ , the piston-cylinder unit 25 with its piston rod 27 being the roller 10 can raise and lower, whereas the piston-cylinder unit 26 on its piston rod 28, the roller 10 'raises or lowers. At the beginning of this process, a pressure control valve 29 is opened; the piston-cylinder units 25 and 26 are pressurized via lines 32 and 33 and extend the piston rods 27 and 28.
  • the drive device 11 or 11 'or 11' continuously exerts a defined moment of force, so that the support rollers 8 and 8 'are constantly pressed against the support rail 7, and only with a small amount Pressure so that the spinning machine frame 1 need not be reinforced. Due to the lifting and lowering rollers 10 and 10 'cross-slopes of the doffer are reliably avoided even on uneven hall floor 4.
  • the drive devices 11 and 11 'and 11 ⁇ are designed so that an automatic locking takes place as soon as the operator, ie the doffer 2, leaves his work area on the flyer 1; the drive device 11 or 11 'or 11' is locked when the support rollers 8 and 8 'no longer abut the support rail 7. This case occurs, for example, when the doffer 2 extends beyond its working area on the flyer 1 in order to drive to a flyer on the right.
  • This locking of the drive device prevents properly that the doffer 2 is tipped over by the drive device due to the lack of contact surface of the support rollers on the support rail.
