Definitions

  • the present invention relates to an automatic walking machine for a textile machine, in particular a spinning or twisting machine, which is equipped with a number of similar production sites, and also to a method for automated operation of the machine.
  • Automatic devices are increasingly being used for operations at the production sites, which automatically move along the production machine and stop at the production site in question as required. These devices are referred to below as automatic walking machines.
  • the automatic walking machines known today are active at a single production site. Once the work to be done at the production site has been completed, the automatic walker controls another production site on request or during a control trip.
  • the functions of the operator stations can be redundant, so that several operator stations can perform identical functions. Furthermore, the functions of the individual operating stations can be in a sequential relationship. This means that the operation of one or more production locations of the textile machine takes place in several partial actions corresponding to several partial functions of the operating station, the partial functions being available in succession or simultaneously in individual operating stations. In principle, a mixture of the concepts mentioned is also conceivable, that is to say the arrangement of redundant operator stations and operator stations that work with different subfunctions.
  • An automatic walking machine according to the invention can make use of its advantages if several textile machine production sites in the immediate vicinity require actions at the same time. If from the Textile machine is expected to have a large working capacity for various tasks of the walking machine, the use of a walking machine according to the invention makes sense.
  • Figure 1 shows the textile machine with a machine head K and production points P, which have the numbers 1,2,3 .... N for their identification.
  • the automatic walker W shifts in the longitudinal direction of the textile machine to take up its working position.
  • Figure 2 shows the basic structure of the automatic walking machine W with different operating stations a, b, c, d, e. These are each designed for different functions.
  • a certain production point P of a textile machine M is in contact with individual operating stations a, b, c as the walking machine W progresses. After completion of operations at the production points P, in front of which the automatic walking machine is located, it can advance by one or more positions. The entire action at a production site can run sequentially in individual sections. This requires additional time for moving the walking machine from one position to the next.
  • the automatic wanderer works simultaneously with several operating stations a, b, c at several production points 1, 2, 3. Its working speed is thus significantly increased without the individual sub-functions having to run particularly quickly.
  • Figure 3b shows a variant of the automatic walking machine with a sequential arrangement of operating stations a, b.
  • the two operating stations a, b each perform a partial function in succession.
  • An empty position 0 is inserted as an example into the row of operating stations. This can be useful if waiting times in the course of the operating operations are necessary, which may be necessary at a certain production site for technological reasons.
  • Figure 3c shows a mixed form of the sequential and redundant arrangement of operator stations a, b.
  • the operating station b is designed twice, whereby one of the two stations can serve as a hidden reserve in the event that one of the stations becomes unusable.
  • Figure 3e shows a further design of the concept.
  • the space required for the individual operating stations a, b, c may be greater than the division of the production sites 1, 2, 3.
  • the division between the operating stations a, b is chosen twice as large as the division of the production locations 1, 2.
  • the automatic walking machine can each advance by the division, that is to say the distance between two production locations 1, 2, or it can advance by two positions, in which case only every second production location is operated during a journey.
  • the production sites that were not initially visited are then served in a second trip.
  • Fig. 4 shows the structure of a walking machine W on a ring spinning machine.
  • a single production site of a ring spinning machine M is subdivided into a roving feed device 119, a drafting device 130, a ring traveler combination 151, 152 and a spindle 114.
  • the ring spinning machine M carries roving bobbins 120 in a frame upper part 101, including the drafting system 130, under which there is a suction tube 141 which opens into a suction channel 140.
  • a pulley 112 which drives spindles 114 via a belt 113, which are seated in a spindle bearing 115.
  • the spindles 114 carry a spinning cop 116 with the wound thread 118 on a sleeve 117.
  • the winding is carried out by a rotor 152 on a ring 151 which is seated in a ring frame 150.
  • a balloon ring 161 on a balloon ring holder 160 and above it a thread guide 171 in a thread guide holder 170.
  • Drives 153, 163 and 173 in the form of tension elements are attached to ring frames 150, balloon ring holder 160 and thread guide holder 170.
  • the drives 153, 163 and 173 are guided in a channel 190 parallel to the longitudinal axis of the ring spinning machine M.
  • the automatic walking machine W can be divided into two sections W1 and W2, which are different Wear operating stations a, y, c, x.
  • the operating station x changes roving bobbins 120.
  • it can also be used, for example, to check the condition of roving bobbins 120 with a sensor x2 on arm x1.
  • a gripper x3 on the arm x1 can on the one hand grasp roving bobbins 120 or operate a clamping device 123 for roving 121 by the gripper 130 pressing a clamping lever 125 against a stop 124 if the supply of roving 121 into the drafting system 130 is to be interrupted.
  • the operating station a with a swivel arm a3 and a telescopic tube a1 can, for example, replace runners 152 which are pushed inside the telescopic tube a1.
  • the telescopic tube a1 can be moved according to the double arrow a2 and additionally pivoted with the movement of the swivel arm a3.
  • a swivel arm a4 with the telescopic tube a1 can also be swiveled.
  • the automatic walking machine W can carry an operating station y on another level, which externally resembles the operating station a, but the operating station y, as mentioned, carries out suction and blowing operations by means of the telescopic tube a1.
  • Another similar operating station c can take auxiliary thread H from a removal point E with a telescopic tube a1 on the same automatic walking machine W, the length of the auxiliary thread being controlled by a metering station Z.
  • a vehicle F In the lower part of the automatic walking machine W, a vehicle F can be seen which carries the sections W1, W2.
  • Another track L in the upper part of the automatic walking machine W provides additional guidance.
  • FIG. 5 shows the configuration of an automatic walking machine with the vehicle F, traction motors, seen from the machine F1 in the raceway L1 and the sections W1, W2 sitting on the vehicle F.
  • the sections W1, W2 can in principle be of the same design and carry different structures W3, W4, which in turn carry the operating stations c, x.
  • Other operating stations a, b can be arranged directly on a section W1, so that different working heights of the operating stations result.
  • the vehicle F can also be adapted to the respective requirements from modules F3, F4, which can be combined as desired.
  • the automatic walker can also be understood as a machine group, with at least two individual machines being coupled or operated in a coordinated manner.
  • the automatic walker W is advantageously designed so that it can also be used for special tasks. Due to a modular structure, which allows a configuration of the automatic walker adapted to the application, great flexibility can be achieved with moderate equipment expenditure.
  • the automatic walking machine W can also be composed of at least two units, which are referred to below as the service automatic machine W5 and the automatic thread applicator W6. Both machines can be coupled via the coupling element K, for example in the lower part of the vehicle modules F3 and F4, it being possible for this coupling to be elastic or rigid. In the case of an elastic coupling, which only ensures the distance of the machines from one another, according to FIG. 5 additional wheels F2 'are required in each case on a vehicle F3, F4.
  • the automatic service machine W5 and automatic thread application machine W6 can be operated individually, although it can be useful if they work in a coordinated manner and run along the textile machine M at a short distance from one another.
  • Such an operating mode can be used, for example, for a preventive replacement of the rotors 152 of a spinning machine M. make sense.
  • the W5 service machine replaces the runners 152. It moves freely from one spinning machine M to another in the manner of a driverless transport device. He automatically sits on a career path L1, which is intended for the automatic thread applicator W6, which is always operating on the spinning machine, and travels behind the automatic thread applicator W6 to one end of the spinning machine M. If the automatic service device W5 is to travel independently from one spinning machine M to another he an additional chassis F ', as indicated schematically in Fig. 4.
  • spinning machines M, M ', M'' stand side by side in a spinning mill, each of which is divided into a central part M2, a gear part M1 and, for example, a control part M3. Runways L1, along which the individual machines can move, run along the middle part M2 on both machine sides. If, for example, a runner change is to be carried out at the individual spinning stations on the spinning machine M ', the service machine W5 must be controlled to the spinning machine M'. It is oriented along a career path L2 that can have a non-contact effect on the W5 service automat.
  • the raceway L2 and the raceways L3 and L3 'branching off in the direction of spinning machines are advantageously embedded in the floor of the spinning mill and act inductively on the service automat W5.
  • Such controls for ground-based vehicles that are in certain directions in one Manufacturing buildings are supposed to move are known from transport technology. It is assumed that the service machine W5, after leaving the track L2, moves along the track L3 ′′ to the spinning machine M ′ in order to change the rotor there.
  • the automatic thread applicator W6 can receive the command on the spinning machine M 'to move in the direction of the gear part M1' along the track L1 in order to expect the service automat W5 there at the end of the track L1. After the arrival of the W5 service machine, both can move in a coordinated manner as a machine group.
  • the coordinated machine group forms, as described above, the automatic walker W.
  • the service machine W5 can also wait for the arrival of the thread applicator W6 at the end of the track L3 '' at the gear part M1 ', which moves monotonously back and forth along the track L1 under program control .
  • the service machine W5 and the thread applicator W6 When the service machine W5 and the thread applicator W6 have started moving together, they drive to the other end of the spinning machine at the control unit M3, M3 ', where the runners of a number of spinning positions are then exchanged.
  • the step-by-step movement of the automatic service machine W5 and the automatic thread application machine W6 can be determined by the working rhythm of, for example, the automatic automatic thread application machine W6, the service machine W5 then following the movements of the automatic thread application machine W6.
  • the individual machines orient themselves with sensors W50 and W60 relative to markings M50 and M60 on the spinning machine M ', as indicated in FIG. 5d.
  • a distance control system can be present, which consists, for example, of a light transmitter W52 on the service automat W5, whose beam W55 reflected by the thread applicator W6 is received by one of the receivers W54a, W54b, W54c.
  • the speeds of the individual machines are controlled by their drives so that the reflected light beam W55 is incident between the receivers W54a and W54c at the receiver W54b.
  • receiver W53 which reports the maximum distance between the individual machines in the case of the receiver W53 when a light beam W56 is incident there, or a minimum distance between the individual machines to their control systems SW5 and SW6.
  • the control systems SW5 and SW6 of the individual machines W5 and W6 are connected to the traction motors F1 and F1 '.
  • the control signals of the receivers W53, W54 etc. determine the running speed of the traction motor F1 and thus the speed of the service automat W5 in relation to the speed of the attaching automat W6 via the control SW5 of the service automat W5. Since the service machine W5 can move in the spinning mill along the track L2, L3, L3 'etc., it must have a collision protection, for example in the form of an elastic bracket W51 according to FIG. 5c, when the drive motor F1 of the service machine W5 deforms instantaneously is stopped to avoid damage or injury.
  • the W52 transmitter and the W54 receiver can also be used for backup.
  • an inductive guide strip L3, L3 'in the floor of the hall is sufficient for moving the service machine W5 from one spinning machine M to another.
  • a battery charger for the batteries B of the service machine W5 can be omitted, since these are only required when moving from one spinning machine M to another.
  • the service life of the service machine W5 on a spinning machine is used to recharge the batteries B according to FIG. 4, a pantograph S being scanned in the spinning machine M or the electrical energy being transmitted inductively. 4, an electrical conductor EL is provided between the automatic walking machine W and the spinning machine M.
  • the rotor change can take place independently of doffing on the spinning machine M and of changing the roving bobbins 120.
  • the reduced speed of the spinning machine during the change of the rotor results in a lower number of thread breaks, so that the automatic thread application machine W6 is largely free for the application of the thread 118 at the production points P after each change of the rotor.
  • the individual operating stations a, b can be controlled in such a way that only the absolutely necessary operating operations have to take place. 6
  • sensors S1, S2, S3 can be arranged before, in or after the drafting device 130 for the roving.
  • Further sensors S4, S5 can track the thread running below the drafting device 130 up to the spindle 116. If, for example, the roving 121 breaks above the drafting device 130, it is sufficient to switch off the relevant production point P of the textile machine by the control ST1 stopping the motor M. At the same time, a thread clamp 123 'must be operated. In this case, only the roving has to be drawn back into the drafting unit 130 again, for example by the operating station a, from the roving spool 120. The other operator stations remain unloaded and the commissioning of the production site concerned takes place earlier. The automatic walker can rather continue its control path in order to turn to another production site P.
  • the thread clamp 123 ' according to FIG.
  • a controller ST1 of the spinning machine according to FIG. 6a evaluates the signals from the sensors S1 ... S5 and communicates via, for example, the electrical conductor EL with a controller ST2 of the automatic walking machine W, which then activates the operating station a, b, etc. to be used in each case.
  • the individual machines can be coordinated, i.e. work interdependently, or work independently.
  • an automatic walking machine W can consist of several sections W1, W2, which can be coupled to one another or each operated with its own drive next to one another with a gap.
  • the sections W1, W2 can perform various special tasks, for example that of a service machine W5 for exchanging the runners 152 or a thread applicator W6 that can attach or take up thread 118 on the spinning head 116, into the spinning organs above it, e.g. Can pull in balloon ring 161 and then attach to the drafting system 130.
  • a further section W3, W4 can perform another function, for example the replacement of a roving spool 120 or the insertion of the roving 119 into the drafting system 130.
  • the combined mode of operation of several special modularly designed machines W1 ... W6 can be used for a reasonable one Effort great flexibility and a high degree of utilization of the machines can be achieved.
