Definitions

  • the invention relates to a device for feeding slivers to a processing machine with at least one sliver guide, which has a guide surface over which the sliver is guided and a housing containing the guide surface, and a method for producing a sliver guide.
  • the disadvantage of this method of monitoring is that the exposed belt guard can fly away or be damaged in addition to the risk of damage, and that when the sliver container is set up in a long row in succession, the operator has to travel long distances, for example to pull the torn sliver end from the rear container to the front Bring machine infeed to connect it to the other torn end and then restart the machine. This increases the downtimes of the machine.
  • the object of the present invention is to avoid these disadvantages and to create a reliable belt monitoring system which increases machine effectiveness in a simple manner.
  • the band guide also has the function of a band monitor, so that in the usual arrangement of the first band guide in the fiber running direction above the sliver can containing the sliver, early detection of band breaks is possible.
  • the housing of the tape guide has an opening on the side of the guide surface.
  • the monitoring device is thus protected against fiber flying and damage.
  • the insertion of the monitoring device into the housing is facilitated in that the housing also has an opening on the side opposite the guide surface.
  • the sensor is expediently connected to a parking device for the machine with electrical connections.
  • a sensor is preferably used which works on a capacitive basis and also makes it possible to detect band breaks which occur after the sliver has passed the band guide and the end of the band in the running direction as a result of the break on the band guide remains lying.
  • Improved tape guidance and scanning is achieved in that the guide surface is flat.
  • the opening in the guide surface is expediently designed as a slot which extends transversely to the running direction of the sliver. A large-area scanning of the sliver is thereby achieved.
  • the housing and the potting compound have approximately the same physical properties. In the case of thermal expansion, for example, there are no gaps between the sealing compound and the housing in which fibers can accumulate.
  • the monitoring device is arranged in the immediate vicinity of a sliver can filled with the sliver, a break in the sliver or the end of the sliver is quickly detected and the operator has to travel short distances to remedy the defect.
  • the senor is electrically connected to a switching device.
  • the switching device preferably contains the actuation functions for remote control of the machine. If the switching device is arranged close to the monitoring device, it is faster for the operator to start the machine again after a defect in the sliver has been remedied, since they have to travel shorter distances to restart the machine. If the electrical connections between the sensor, switching device and storage device are essentially arranged in closed channels, the risk of damage is reduced. If a triggering of the monitoring device can be indicated by an optical signal transmitter assigned to it, there is the advantage of quick identification of a defective fiber sliver. If the optical signal transmitter is arranged in the immediate vicinity of the monitoring device, the operator is able to reach the defective sliver point in the shortest possible way.
  • the invention further relates to a method for producing the tape guide of the described device with an integrated scanning device, which is characterized in that the housing is stretched upside down on a stamp and the sensor is inserted into the housing from the side opposite the guide surface and cast therein becomes.
  • Figures 1 and 2 show a tape guide 1 made of aluminum with a housing 2 which is fastened on a holding tube 3 by means of screws 31.
  • a polished guide surface 20 on the housing 2, over which the sliver slides and is fed to a processing machine, for example a draw frame. Sliding of the fiber sliver from the sliver guide 1 or the guide surface prevent side rims 11 which limit the guide surface 20 on both sides.
  • the guide surface 20 is designed as a flat surface.
  • the housing 2 has an opening in the region of the guide surface 20 which is designed as a slot 21.
  • the slot 21 extends transversely to the running direction of the sliver up to near the side rims 11.
  • the housing 2 On the end of the housing 2 opposite the guide surface 20, the housing 2 also has an opening 22 which allows free access to the interior of the housing 2.
  • a monitoring device is used within the guide surface 20, which interrogates the presence and the running of the sliver.
  • the monitoring device is inserted into the housing 2, where it is protected against contamination and damage.
  • a sensor 4 that works on a capacitive basis is preferred as the monitoring device.
  • the sensor 4 is encapsulated in the housing 2 and protrudes into the slot 21 at one end.
  • the distance a between the upper edge of the sensor 4 and the upper edge of the guide surface 20 is advantageously a maximum of 1.5 mm, so that a reliable response of the sensor 4 is still ensured.
  • the sensor 4 is covered by a sealing compound 23.
  • the sensor 4 is cast in the housing 2 of the tape guide 1 with the aid of a device shown in FIG.
  • the band guide 1 with its flat guide surface containing the slot 21 is placed on a stamp 5 with a likewise flat surface and pressed onto it by means of a tensioning device 51.
  • part of the potting compound 23 is introduced into the housing 2 through the opening 22 opposite the slot 21 in the housing 2, so that the slot 21 and part of the housing 2 are filled with potting compound 23.
  • This first part of the casting compound 23 is expediently introduced by means of a brush, as a result of which air pockets in the casting compound 23 are eliminated.
  • the senor 4 is inserted into the housing 2 and the potting compound 23 is refilled up to its upper edge. A precise fixation of the sensor 4 when it is inserted into the housing 2 is ensured by a holding device 52. By potting the sensor 4 in the housing 2 "upside down” it is achieved that air bubbles located in the potting compound 23 move away from the guide surface 21, which is now also a scanning surface, and a homogeneous structure is created at this point. After the casting compound 23 has hardened, the guide surface 20 is polished in order to avoid any fiber splitting off from the fiber sliver.
  • Figure 4 shows a feed rack which serves to feed a plurality of slivers to a draw frame or other processing machine.
  • a central tube 7 extending in the sliver running direction, four holding tubes 3 are fastened at a distance, at the two ends of which the tape guides 1 with an integrated tape monitor are arranged.
  • the tape guides 1 are located above or at least in the immediate vicinity of sliver cans 8 filled with sliver, only one of which is shown.
  • the sliver taken from the sliver cans 8 is fed to the processing machine 6 via the guide surface 20 of the sliver guide 1 and, depending on the distance of the sliver can from the machine, via further sliver guides. For cost reasons, however, no monitoring devices are used in the other band guides, not shown.
  • the sensors 4 integrated in the band guide 1 are connected to a storage device 45 and switching devices 46 attached to the feed frame by means of electrical connections 41, 42, 43 and 44, which are accommodated in the holding tubes 3 and the central tube 7 and are protected from contamination and damage. If a sliver breaks between the sliver can 8 and the sliver guide 1, the sensor 4, after passing the sliver end, detects the absence of the sliver and emits a signal to the parking device 45, which stops the drive motor of the machine. The sensor 4 also detects a sliver break that occurs between the sliver guide 1 and the machine 6, ie the sliver no longer runs over the guide surface 20, but remains on it.
  • the sensor 4 then also emits a signal for stopping the machine to the stopping device.
  • the two band ends remain so close together that the operator can grasp them effortlessly and quickly connect them to one another.
  • the machine 6 can therefore be switched on again in a very short time by actuating one of the switching devices 46 Be put into operation.
  • the switching device 46 contains the operating functions for remote control of the machine, so that the operator can start the machine 6 from the point of the sliver break. So that the operator has to travel short distances and the downtime of the machine 6 is as short as possible, the switching device 46 is arranged near the belt guide 1, in which the sensor 4 is located.
  • the optical signal transmitters 47 are arranged in the immediate vicinity of the monitoring device. When the monitoring device is triggered, they indicate that the operator has to look for a sliver break at this point. This configuration of the device additionally shortens the downtime of the machine 6.
  • the arrangement of the switching devices 46 is chosen in Fig. 4 such that the switching device 46 can be operated from two monitoring devices.
