Abstract

  In order to simplify the control of work processes between the ring spinning machine and the moving cleaner arranged corresponding to the ring spinning machine, both in terms of equipment technology and function, the moving cleaner control device is provided with a ring. It has been proposed to be integrated into a spinning machine controller. This eliminates the need for a special control device for the moving cleaner. It is particularly advantageous that the ring spinning machine is provided with an underwinding rest remover in both spindle rows for removing the underwinding rest unwound from the underwinding region. In this case, the moving cleaner includes a suction device, the suction device has a suction opening for the underwinding rest remover, and the underwinding rest is sucked into the suction opening. In this case, synchronous travel between the mobile cleaner and the underwinding rest remover must be ensured. This is particularly simple if the motion control of both devices or all three devices is carried out with the same control device, ie the control device of the ring spinning machine. It is also advantageous to integrate the control device of one moving cleaner into the control device of the ring spinning machine or the pre-spinning machine.

Description

  The present invention relates to a ring spinning machine or a pre-spinning machine having a large number of working parts and a moving cleaner that can travel along the working parts by an electric motor. In a further configuration of the invention, the spinning machine is equipped on each machine side with an underwinding rest remover that can run synchronously with the moving cleaner along the work site by means of an electric motor.

Prior Art The function of a moving blower in a ring spinning machine or a pre-spinning machine is to release fiber waste and dust deposited on the spinning machine, and therefore the moving blower travels along the spinning machine. In this case, the moving blower loads fiber waste and dust with a blow air flow. However, mobile blowers associated with suction devices are also known.

  Spinners and moving cleaners are manufactured and provided by different companies. It is therefore advantageous if the spinning machine and the moving cleaner can be combined freely. Accordingly, each of the working devices has a self-sufficient control device. The control device makes the work type of the mobile blower irrelevant from the spinning machine on which the mobile blower operates. Coupling exists as long as both devices consider or influence each other if both devices are discordant. Examples of discordant cases include bobbin replacement processes that may be hindered when the blowing action continues or manipulations of the spinning site of the machine that are hindered by the operator.

  However, the cooperation between the ring spinning machine or the pre-spinning machine and the moving blower is significantly beyond the consideration of the discordant case. For example, it is advantageous that the action of the moving cleaner is more closely matched to the requirements of the spinning machine. If the actions of the moving cleaner and the machine are strongly meshed with each other, the work of the machine and the moving cleaner should be able to better coordinate with each other.

  The subject of the invention which appears to be particularly advantageous is a ring spinning machine having one underwinding rest remover in addition to a moving cleaner or -in the case of a double-sided ring spinning machine-two underwinding rest removers. . The underwinding rest remover generates lint that is collected and removed by suction of the moving cleaner. For this purpose, the underwinding rest remover and the moving cleaner must be moved along the ring spinning machine periodically.

  According to DE4140049C2 specification, a moving cleaner which can run on the ring spinning machine's cage along the working part of the ring spinning machine and has both a suction action and a blowing action, and a ring spinning spindle on both machine sides A ring spinning machine is known which has an underwinding rest remover which is moved along the underwinding area of the ring spinning spindle along the axis. Depending on the underwinding rest remover, the underwinding is released from the spindle and sucked out using a suction nozzle disposed in the moving cleaner. To achieve this, the underwinding rest remover and the moving cleaner suction nozzle are always moved in opposition and synchronized so that the unwinded unwinding is immediately sucked into the suction nozzle and not released to the surroundings. There must be.

  This synchronization is achieved in that both the moving cleaner and the underwinding rest remover are moved by a single rope guided along the ridge and along the spindle via a turning roller. This requires very long ropes and complex rope guides for recent large machine lengths. Moreover, the exact confrontation of the underwinding rest remover and the moving cleaner cannot be obtained due to the elasticity of the long rope.

  Therefore, according to DE 4231737 A1, an electronic synchronous control device is proposed in which the traveling drive device of the moving cleaner and the underwinding rest remover is controlled by a common control device. Therefore, in this case, a common third control device other than the separate control devices for the moving cleaner and the ring spinning machine is required for the additional device for the ring spinning machine.

DETAILED DESCRIPTION OF THE INVENTION Accordingly, it is an object of the present invention to achieve closer cooperation between various spinning machines and moving cleaners. The object of the present invention has been solved by integrating the operation control device of the mobile cleaner, which has been self-sufficient until now, into the operation control device of the spinning machine. The spinning machine control itself also controls the operation of the mobile cleaner. This is the only control device and can be performed more favorably than a separate control device. This also provides the advantage that no control device is required in the mobile cleaner.

  A ring spinning machine which is particularly advantageous for the present invention is a ring spinning machine having one moving cleaner and one or, in the case of a two-sided ring spinning machine, two underwinding rest removers. In any case, the underwinding rest remover generates lint to be collected and removed by suction flow by a moving cleaner. For this purpose, the underwinding rest remover and the moving cleaner must move along the ring spinning machine synchronously with each other.

  Thus, the machine controller also takes control of the moving cleaner according to the needs of the ring spinning machine or the pre-spinning machine. This brings about simplification both in terms of apparatus technology and control technology. The mobile cleaner is provided with at least one sensor for this purpose, which tells the load to the machine controller. The machine then draws the desired result for the mobile cleaner and / or control of the machine.

  The sensor can be a contact sensor, for example. This contact sensor senses a person standing on the moving path of the moving cleaner. The machine controller then determines whether the mobile cleaner stops and waits for the person to leave or whether the mobile cleaner changes its direction of motion. Or, in order to prepare a cup change process in which the machine controller is informed of the timing, the machine controller may remove the moving cleaner from the spindle area in a timely manner so that the moving cleaner does not interfere with the start of the cup changing process. Start moving to.

  Especially when the ring spinning machine already has a control device for the underwinding rest remover integrated in the ring spinning machine, with respect to the parallel synchronization, which makes the required pair of two or three cleaning devices. As a result of the integration, further significant simplification is achieved both in terms of device technology and control technology.

  In order to be able to control the mobile cleaner properly, the machine controller must be informed of the specific location of the mobile cleaner. For this purpose, the mobile cleaner can be equipped with an absolute value generator. This absolute value generator tells the machine control unit the measured value corresponding to its position along the machine. Of course, other sensors can be used for this purpose, for example an incremental generator.

  In many cases, however, it is sufficient to provide sensors at the end of the movement path of the moving cleaner and the underwinding rest remover to inform the end of the cleaning device at this end position. The position of the cleaning device is then neutralized, so that the cleaning device starts to move from the same basic position at the same time.

  Further configurations of the invention are described in the dependent claims.

  Hereinafter, the present invention will be described in detail with reference to the drawings showing a plurality of embodiments of the present invention by taking a ring spinning machine as an example.

  Hereinafter, it should be noted that even if a ring spinning machine is described, this may be a pre-spinning machine. Of course, the description of the control of the underwinding rest remover does not apply to the pre-spinning machine.

  The ring spinning machine has a start frame 1 and a terminal frame 2, and a flange 3 extends mainly between the start frame 1 and the terminal frame 2, and a draft mechanism 4 and a spindle bench 5 extend on both sides. . The spindle bench shown here has a number of spindles, which are indicated only by their centerline 6. Further, the ring spinning machine has a working mechanism (not shown) such as a ring bench and the like and an additional device such as a cup changing device. Further, the ring spinning machine is provided with a control device 7, and the working device and the additional device of the spinning machine can be functionally and correctly controlled through the outlet 8. A common ring spinning machine is constructed on both sides, that is, it has a draft mechanism and a spindle bench on both sides.

  Further, the ring spinning machine is provided with a moving cleaner 9, and the moving cleaner 9 keeps lint and dust away from the spinning machine. The moving cleaner 9 can run on a rail extending along the ring spinning machine via the track roller 10 above the upper side of the flange 3. The moving cleaner 9 has a blow air ventilator driven by a motor and has two blow hoses 12. The blow hose extends downward on both sides of the ring spinning machine and allows the blow air flow of the blow air ventilator to flow along the ring spinning machine. The movement of the moving cleaner 9 along the ring spinning machine is performed by driving at least one of the track rollers 10 by a drive motor 13.

  The mobile cleaner also has another device, such as a contact sensor 14. The contact sensor 14 senses an approaching obstacle or an approaching end point of the motion path. In many cases, mobile cleaners are also equipped with a suction device. With this suction device, lint and dust are sucked up from the floor, for example, using the suction shoe 15. In this case, a suction hose is embedded in the blow hose 12. The suction hose can be loaded with a suction air flow of a blow air ventilator. The waste is collected in a mobile cleaner reservoir. The reservoir has a sensor that senses when the reservoir is full and directs the contents of the reservoir to empty into the stationary waste collection container 16.

  For example, a signal from a sensor such as a moving cleaner 9 is transmitted to the control device 7 of the ring spinning machine via a multi-conductor or a bus-coated conductor 17. The signal is then processed functionally properly and other functionally appropriate control signals for the mobile cleaner are provided. This signal is again transmitted as a control signal to the mobile cleaner via the conductor 17. Therefore, the control of the function of the mobile cleaner 9 is integrated into the ring spinning machine controller 7, so that the mobile cleaner need not have its own controller. The moving cleaner is connected to the control device 7 of the ring spinning machine via an interface 19, and the control signal of the control device is converted into a control signal that can be understood by the moving cleaner at this interface. This interface can be integrated into the ring spinning machine or the mobile cleaner 9. The control capacity and control intelligence of the control device 7 of the ring spinning machine are set so that additional control functions for the mobile cleaner can be easily assumed.

  In another configuration, the ring spinning machine includes a device for removing underwinding from the ring spinning spindle 6 as shown in FIGS. For this purpose, the ring spinning machine has an underwinding region 21 underneath each cup 20, which is shown only in FIGS. 2 and 3. This underwinding region 21 is wound with some thread windings for bobbin replacement, and from this thread winding, winding onto a newly inserted winding tube can be started. This underwinding must be removed over time. For this purpose, one underwinding rest remover 22 is used on each machine side. The underwinding rest remover 22 is fixed to an endless tension belt 23, and the underwinding rest remover 22 is moved along the row of the spinning spindles 6 at the height of the underwinding region 21. The tension belts are guided at both ends of the spindle bench 5 via one turning roller 24 and one guide roller 25, respectively. In this case, one of the diverting rollers is provided with a drive motor 26.

  The underwinding rest remover 22 includes a needle cloth having sharp teeth, and the underwinding is cleaved by the teeth. This underwinding is released from the ring spinning spindle by centrifugal action by the centrifugal acceleration of the rapidly rotating ring spinning spindle. This released underwinding rest must be removed, for which a moving cleaner 9 is involved. For this purpose, the suction air of the suction cleaner of the mobile cleaner is led to both underwinding rest removers via two suction hoses 27. Therefore, the suction hose 27 is connected to two suction openings 28. In this case, it must be ensured that this suction opening 28 always faces the underwinding rest remover 22.

  In order to achieve this, in the first embodiment of the invention according to FIG. 2, the positions of the three working mechanisms, the underwinding rest remover 22 and the moving cleaner 9 are neutralized at the end of the movement path, respectively. The In other words, the three devices are guided to the same position and can depart from this same position again for return travel. For this purpose, the control device 7 of the ring spinning machine allows the control device 7 to move the three cleaning devices 9 and 22 to their end positions, and the return travel is only after all the devices have reached the end positions. It is programmed to start. The arrival of the end position is ensured by the return travel of the moving working device being delayed until all working mechanisms are informed that the end position has been reached.

  Alternatively, a sensor 29 or 30 is arranged at the terminal position of the moving cleaner 9 and the underwinding rest remover 22, and each of the working devices moved by the sensor 29 or 30 is detected, and the signal conductor 17 is Via the ring spinning machine control device 7. This signal causes a return run to start after all three sensors at the end of the motion path have issued a run-in signal.

  However, an incremental signal generator 31 or 32 is provided for each one of the deflection rollers 24 of each of the tension belts 23, and this incremental signal generator 31 or 32 detects the rotational movement of the guide roller or track roller. It is also advantageous to do so. The incremental signal generators 31 and 32 have an incremental disk 33 and an incremental sensor 34, and can transmit the signals to the control device 7 of the ring spinning machine via the control lead 17.

  The ring spinning machine control device 7 compares the increment steps coming from the three incremental signal generators 31 and 32, and one of the moving work device, the moving cleaner 9 or the underwinding rest remover 22 is In the preceding case, the parallel driving is restored by narrowing down the driving motor 13 or 26 with the driving energy or raising it if it is behind. If the drive motor is configured as a synchronous motor, its supply frequency must be changed considerably. The supply frequency is supplied to the drive motor via the signal conductor 18.

  The invention has been described on the basis of ring spinning machines on both sides. However, it goes without saying that the solution of the present invention can also be realized in a ring spinning machine or a pre-spinning machine on one side.
