Definitions

  • the invention relates to a warp beam pallet truck for changing a warp beam in a weaving machine, the warp beam of thru axles in the weaving machine can be received and the pallet truck has a pivotably mounted support beam, in the free and open ends of which sliding beams that can be adjusted to the length of the warp beam are inserted, and each Sliding beam has a support arm having a pipe gripper.
  • Kettbaum pallet trucks with hydraulically movable support bars and with support arms which are axially displaceably received in the support bar and which are equipped with a pipe gripper for receiving the warp beam pipe are known.
  • These support arms have a fine height adjustment to ensure that the thru axles can be removed and inserted correctly when changing the warp beam. That means, in particular before inserting the thru axle, the support arms of the lifting truck with the warp beam tube must be precisely aligned with the bearing of the thru axles in the weaving machine, both in height and in depth.
  • the bearing hole for the quick-release axle and the quick-release axle holder in the warp beam tube must be aligned opposite one another in order to be able to insert the quick-release axles into the receptacle of the warp beam tube.
  • the warp beam After the warp beam has been inserted into the weaving machine, it must also be aligned laterally to the weaving machine in order to ensure a parallel and right-angled thread course from the warp beam to ensure the heald frames. This alignment is also time-consuming and affects the productivity of the weaving machine.
  • the lifting arms of the lifting truck When the empty warp beam is removed from the weaving machine, the lifting arms of the lifting truck must also be precisely aligned in height and depth with the warp beam tube. If such alignment is only inaccurate, it is not possible to pull out the thru axles as a result of the level difference between the thru axle and its receptacles and the resulting clamping effect.
  • a warp beam carriage with lifting arms for carrying a warp beam is known from the published patent application DE-A1-31 30 328.
  • the lifting arms are designed to be pivoted up and down by means of a hydraulic piston-cylinder unit about an axis lying parallel to the longitudinal axis of a longitudinal bar.
  • a hydraulic piston-cylinder unit To improve the maneuvering properties of the lifting truck, at least one of two cross bars, which form the chassis of the lifting truck with the longitudinal bar, is arranged so as to be adjustable in the direction of the longitudinal axis of the longitudinal bar.
  • DE-OS 31 30 328 does not disclose any technical teaching, according to which the warp beam carriage can be positioned in or out of the weaving machine for the purpose of transferring or taking over a warp beam in such a way that warp beams which are stored in the weaving machine by means of thru axles without a manual one Readjustments in the x, y and z axes are sufficient.
  • the published patent application DE-A1-33 30 308 discloses a warp beam insert carriage which aims to minimize the total length of the warp beam insert carriage for the purpose of favorable maneuverability, favorable cornering behavior and to maintain the smallest possible swivel radius under load.
  • the support tube having the load-carrying means is designed as a center piece, into which a respective side rail fixed telescopic tube is telescopic. This allows the warp beam insert carriage to be adjusted to the respective nominal length of the warp beam to be transported.
  • Kettbaum insertion carriage eliminates the need to manually level the thru-axle bearing or the thru-axle receptacle when transferring or taking over the warp beam into or from the weaving machine is not disclosed.
  • the warp beam insert trolley acc. DE-OS 33 30 308 is therefore not suitable for inserting a warp beam with thru-axle bearing into the weaving machine without having to take additional manual measures.
  • the published document FR-A1-2 281 401 discloses alternative solutions of a device independent of a warp beam transport carriage for storing a warp beam equipped with a warp beam tube, which is carried by thru axles for the rotating mounting thereof.
  • the individual devices aim to receive a warp beam that is not rotatably mounted in a first level at its tube ends and to lift it to a second level for the purpose of its rotating mounting.
  • FR laid-open specification also does not disclose any technical teaching that a warp beam transport carriage can be positioned in or out of the weaving machine for the purpose of transferring or taking over a warp beam in such a way that warp beams that are stored in the weaving machine by means of thru axles can be moved without a manual one Readjustment get along.
  • the object of the invention is therefore to develop a Kettbaum pallet truck of the aforementioned type in connection with a weaving machine in such a way that three-dimensional positioning of the Kettbaum pallet truck on the weaving machine is made possible without the purpose of producing and releasing the thru-axle connection between the warp beam and the weaving machine a manual readjustment on the warp beam holder is necessary.
  • an arm limiting the travel path of the lifting truck into the weaving machine is provided with a stop element on the sliding spars, parallel to the supporting arms equipped with the pipe gripper, that means for leveling the warp beam carried by the pipe gripper with the arm is provided on the arm the thru-axle bearing of the weaving machine is arranged in each case and that the lifting truck and the weaving machine have provisions on at least one side for fixing the lifting truck to the side in the weaving machine.
  • each stop element and each means leveling the relevant support arm can be placed on the respective thru-axle bearing of the weaving machine that receives the thru-axle.
  • An adjustable element which is arranged at the free end of an arm fixedly connected to the sliding beam, acts as a stop and comes with its free end to the center of the housing of the thru-axle bearing of the weaving machine.
  • the contact surface of the free end of the adjustable stop element is expediently slightly spherical.
  • leveling means In order to ensure that the warp beam is received by the support arms of the lifting truck in such a way that an unimpeded connection of the warp beam and the weaving machine is ensured by means of the thru axles, leveling means according to the invention are provided which completely compensate for the possible level differences between the thru-axle receptacle of the warp beam tube and the thru-axle bearing of the weaving machine compensate.
  • the leveling means consist of a swivel lever, which is preferably arranged on the arm and is rotatably mounted about an axis, the free lever arm of which engages over the thru-axle bearing of the weaving machine and holds a role that determines the leveling.
  • pivot lever is connected to an actuating device, which is preferably supported on the arm, which can be, for example, a hydraulically operated piston-cylinder unit, a linear motor or a threaded spindle, for example, which can be actuated by hand.
  • actuating device which is preferably supported on the arm, which can be, for example, a hydraulically operated piston-cylinder unit, a linear motor or a threaded spindle, for example, which can be actuated by hand.
  • the sliding bars together with the carrying bars can be rotated by at least an amount which represents the level difference between the center axis of the warp beam tube and the center axis of the thru-axle bearing and which can be in the millimeter range.
  • the support bar is pivotally mounted in a lifting trolley.
  • the leveling roller of the swivel lever viewed in the direction of travel of the lifting truck on the weaving machine, is preferably brought to bear on the bearing housing behind the geometric longitudinal axis of the housing of the thru-axle bearings.
  • provisions are made on the weaving machine for the lateral positioning of the lifting truck in the weaving machine consist of a fixing element which is preferably fixedly arranged in the area of the bearing housing of the thru axles and which, with the side-fixing arrangements on the lifting truck, guides the lifting truck immediately before it reaches its operating position in the weaving machine guaranteed.
  • These side-fixing arrangements consist of at least two fixing rollers arranged axially parallel in the area of the depth stop.
  • the advantage of the warp beam lift truck according to the invention is that the previously necessary and manual alignment of the warp beam lift truck lifting out of the weaving machine and inserting it into the machine is completely eliminated.
  • the thru-axles and axle receptacles are treated more gently and the life of the thru-axle and, in particular, the bearings is considerably extended.
  • the solution according to the invention also has a decisive influence on reducing the time previously estimated for a warp beam change and increases the productivity of the weaving machine.
  • the weaving machine 3 has a left thru-axle bearing or bearing housing 5 and a right thru-axle bearing 5 ', in which the corresponding thru axles 4, 4' are accommodated in an axially displaceable manner.
  • the warp beam pallet truck 1 also shown schematically, for warp beams which are coupled to the weaving machine via thru axles, according to the invention essentially consists of a crossmember 22 which receives a rotatably mounted support beam 6 in its crossmember arms.
  • a crossmember 22 which receives a rotatably mounted support beam 6 in its crossmember arms.
  • sliding beams 7, 7 ' are provided, which are axially displaceably mounted in the support beam 6 and are detachably connected to the support beam by corresponding locking means 6a, 6b.
  • each sliding spar 7, 7 ' receives a support arm 9, 9' which is axially adjustable on the sliding spar and is designed at its free end as a tubular gripper 8, 8 '. Due to the axial displaceability of the support arms 9, 9 ', these can be adapted to the respective width of the warp beam receptacles.
  • FIG. 1 also shows a fixing element 25 arranged on the weaving machine 3 with a wedge-shaped nose and parallel centering surfaces against which centering or fixing rollers 31 arranged axially parallel run in the area of the arm 10 of the lifting truck 1.
  • the means 15, 15 'leveling the support arm 9, 9' are shown in FIGS.
  • the means 15, 15 'which level the height of the support arm 9, 9' consist of a piston-cylinder unit 21, 21 'which is articulated on the arm 10, 10', the piston rod 20, 20 'of which is also attached to the arm 10, 10 'articulated pivot lever 18,18' is connected.
  • the pivot levers 18, 18 ' are designed such that they overlap the bearing housing 5.5' when the stop element 16 lies against the bearing housing 5.5 'in such a way that the leveling roller 19, 19' arranged at the free end of the pivot lever 18, 18 'eccentrically specifically behind the longitudinal axis 24 of the bearing housing 5.5 'on the bearing housing.
  • This eccentric system causes the force generated on the bearing housing 5.5 'by the piston-cylinder unit 21.21' and exerted on the bearing housing by the leveling roller 19.19 'to force the Kettbaum pallet truck 1 and thus the arm 10.10' with stop element 16 remains in the stop position on the weaving machine during the leveling process. This means that a force acts which pulls the arm 10, 10 'with the stop element 16 against the bearing housing 5.5'.
  • the adjustable stop element 16 is shown at the free end of the arm 10, 10 ', which is screwed centrally into the end face of the arm 10, 10', which is closed with a sheet metal 29, and secured by means of the lock nut 32.
  • the surface 30 of the stop element 16 which comes into contact with the bearing housing 5.5 ' is preferably spherical in order to achieve a point contact and to possibly result in vertical displacements between the support arm 9.9' and the housing bearing resulting from the leveling of the support arm 9.9 ' 5.5 'to be carried out with little friction.
  • the leveling roller 19, 19 'on the pivoting lever 18, 18' can also be adjusted in height in accordance with the direction of the arrow 33 via an adjusting element (not shown).
  • Kettbaum lift truck 1 moves with the full Kettbaum 2 in the entry direction 23 up to the position specified by the stop elements 16 in parallel in the weaving machine 3.
  • the motorized Kettbaum pallet truck 1 runs, limited by the Stop elements 16, up to the bearing housing 5.5 'of the weaving machine 3.
  • the leveling roller 19 is activated by hydraulic action on the working cylinder of the piston-cylinder unit 21, 21'.
  • the leveling means 15 are subsequently opened so that the support arms 9, 9 ′ of the lifting truck 1 can be lowered.
  • the warp beam pallet truck is then moved out of it parallel to the weaving machine by uncoupling the side fixation and prepared for a next warp beam change.
