Definitions

  • Transport systems for moving cop changing apparatus from one ring spinning machine to another consist of trucks traveling on tracks which run on one side of the spinning machines.
  • the trucks are ordinarily powered by batteries independently of any stationary power source.
  • a luminous signal or the like indicates that a spinning machine is ready for the removal of the cops
  • the truck is driven by an operator to this machine along with the cop changer which it carries, and is brought into a precise position opposite the end frame of the ring spinning machine in question.
  • guide marks are applied to the front of the truck and to the corresponding place on the floor in front of the ring spinning machine where the truck is brought to a stop,
  • the truck is then brought into precise coupling position by means of hand wheels. This precise position for the coupling of the truck is necessary to enable the cop changer to be placed on rails running along another side of the ring spinning machine and are perpendicular to the truck tracks on which the cop changing apparatus is transported.
  • the truck is connected to a stationary power source at the ring spinning machine for operation of the cop changer and for charging of the batteries on the truck.
  • the centering apparatus consists of a centering cam and a center locator specifically adapted to the centering cam, one being disposed on the side of the ring spinning machine facing the truck and the other on the side of the truck facing the spinning machine, so as to be movable one toward the other.
  • the centering cam or the center locator is disposed on a coupling carriage mounted on the truck and displaceable crosswise to the direction of travel of the truck, so that the coupling movement simultaneously produces centering.
  • This design permits a horizontal movement of the truck into the coupling position.
  • a further characteristic of the invention consists of the rails and supporting bars for the cop changing apparatus are constructed as centering parts which are elastically displaceable vertically. In this manner dilferences in height between the ring spinning machine and the truck, such as those produced by irregularities in the floor or tracks, can be compensated.
  • a longitudinal travel limit switch is installed which stops the motor that propels the truck and at the same time starts the motor of the coupling carriage.
  • the coupling carriage motor drives the coupling carriage trans versely to the direction of travel of the truck, engaging the centering cam with the center locator, to the center position defined by the centering apparatus and then a transverse travel limit switch stops the coupling carriage motor.
  • a retarding switch located ahead of the longitudinal travel limit switch can first reduce the truck speed when it is operating at high speeds in order to achieve more accurate halting of the truck in the operating range of the centering apparatus.
  • FIG. 1 is a perspective view of a coupling carriage which carries the cop changer and is disposed on a truck;
  • FIG. 2 shows the introduction position to the centering of the truck in the coupling position
  • FIG. 3 shows the electrical control circuit diagram of the motors
  • FIG. 4 shows a detail of a further improvement of the centering of the system according to the invention.
  • the truck transport consists of a truck 1 which travels on wheels 2 and is guided by tracks 3 along one side of adjacently located ring spinning machines and carries the cop changing apparatus 5 at one end of the truck 1.
  • the truck 1 is composed of a chassis, shown in broken lines as illustrated in FIG. 1, and a coupling carriage, displaceably mounted therein, which is shown in solid lines, also illustrated in FIG. 1.
  • the truck 1 is driven by a motor TM, which draws its power from batterys (not illustrated) carried on truck 1.
  • the batteries also supply the power need for motor SM, which drives the coupling carriage.
  • the coupling carriage is formed from a front cross member 43, a middle cross member 44, and a rear cross member 45, joined to one another by rods 46 which are mounted on bearings 47 so as to be longitudinally displaceable thereon, and also joined together by rails 41 and supporting bars 42.
  • the rods 46 are positioned to cause the coupling carriage to be displaced crosswise to the direction of travel of the truck transport.
  • Rails 41 and supporting bars 42 serve as the rails and supports for the cop changer and are positioned to match the rails 41 and supporting bars 42 shown inFIG. 2 (and in FIG. 4).
  • a centering cam 6 is provided on the side of the front cross member 43 facing the ring spinning machine.
  • the center locator 61 co-operating with the centering cam 6 is located on the front end of the ring spinning machine facing the longitudinal side of the tracks 3 for the truck transport.
  • An electrical plug connector 62 is also located on front cross member 43, the mating electrical outlet connector being mounted on the front end of the ring spinning machine.
  • switch 7 or 71 When either switch 7 or 71 has been depressed to holding position 7" or the equivalent for switch 71 the switch remains in the second holding position until truck 1 comes into the general aera of the ring spinning machine that is to be unloaded.
  • cam 31 mounted on the ring spinning machine operates retarding switch 10 or 13, depending on the direction of travel from which the truck transport approaches.
  • the driving motor TM of the truck continues to run at slow speed until longitudinal travel limit switch 12 is depressed by cam 32 also mounted on the ring spinning machine (switch position 12).
  • control switch 11 and cam 33 interact only when truck 1 with the coupling carriage are properly situated so that the centering apparatus on both the truck transport and the ring spinning machines can be engaged correctly, allowing the coupling action to follow the normal contours of the centering cam so as to achieve precise centering simultaneously.
  • Motor SM of the coupling carriage shown in FIG. 2 (and FIG. 1) drives, through gears 66 and 67, a threaded spindle 68 which is rotatably mounted in bearings 76 situated on the chassis of the truck and, by means of the middle cross member 44 or a nut 40 fastened to the cross member, displaces the coupling carriage in the direction of the ring spinning machine.
  • the displacement of the coupling carriage brings centering cam 6 into engagement with center locator 61 mounted fixedly on one or the other unit.
  • the truck transport is moved longitudinally of the ring spinning machine and guided to a precise center position defined by the profile of the centering cam wherein the rails 41 and supporting bars 42 of the coupling carriage and the rails 41' and supporting bars 42 of the ring spinning machine are brought into perfect alignment with each other, respectively.
  • the centering cam 6 may be fastened to the ring spinning machine and the center locator 61 to the coupling carriage, or the reverse may be the case. In addition, it is also feasible that the center locator 61 or the centering cam 6, as the situation might warrant, would better function when fastened to the floor in front of the ring spinning machine.
  • transverse travel limit switch 74 When the coupling carriage and ring spinning machine centering apparatus function is completed, as indicated in broken lines in FIG. 2, motor SM of the coupling carriage is disconnected by transverse travel limit switch 74 being depressed to position 74' (FIG. 3).
  • transverse travel limit switch 74 In addition to transverse travel limit switch 74 and for reasons of safety, a slip disk coupling can be incorporated in the coupling carriage drive.
  • the extremities of rails 41' and supporting bars 42' mounted fixedly to the ring spinning machines are connected to pivotable extension members 48 and 49, respectively, which are elastically movable vertically.
  • the extension members 48 and 49 are pivotably mounted in line with rails 41' and supporting bars 42', respectively,
  • extension members 48, 49 are shaped to be center locators, and the free ends of rails 41 and supporting bars 42 on the coupling carriage are shaped to be centering cams as illustrated in FIG. 4.
  • extension members 48, 49 engage the free ends of the matching rails 41 and support bars 42 on the coupling carriage, as the coupling carriage i displaced towards the ring spinning machine, and are shifted into the required vertical position so that a smooth passage of travel is provided between the rails 41 and support bars 42 of the coupling carriage and those of the ring spinning machine for transfer of the cop changing apparatus from one to the other and back again.
  • the electrical plug connector 62 i also similarly constructed for precise joining to the electrical outlet connector located on the ring spinning machine. This connection to a stationary power source is for the purpose of charging, during the cop changing process, the batteries used to drive the truck and coupling carriage motors and also can be applied to supply the required power to the cop changing apparatus.
  • a coupling carriage mounted on the truck, formed by three cross members joined to one another by rods which are rotatably mounted on bearings so as to be longitudinally displaceable thereon, and by rails and supporting bars which serve as rails and supports for the cop changer and match the rails and supporting bars on the ring spinning machines, ⁇ means for automatic speed control of said truck approaching each ring spinning machine, means for driving said truck from one ring spinning machine to another, means for driving the coupling carriage to cause centering thereof to align the cop changer for transferring onto the rails and cop removal action," power means for transferring the cop changing apparatus from said truck along the ring spinning machine rails, and a centering apparatus that defines the precise center coupling position of the matching rails of the transport truck.
  • the means for automatic speed control of said truck approaching each ring spinning machine comprises cam actuatedswitches retarding truck from maximum speed to predetermined speed by reducing applied power, and cam actuated switches retarding truck from maximum speed to predetermined speed by reducing applied power, and cam actuated switches retarding truck from predetermined speed to stop within a predetermined range.
