Definitions

  • the invention relates to a method for operating a can changer, a can changer set up for this purpose and a textile machine equipped therewith.
  • Can changers are used to automatically exchange a can filled with fiber material for an empty can so that it can be filled.
  • a first concept relates to so-called rotary can changers, which move empty cans from a guideway by means of a turnstile with usually three arms around the center of rotation of the turnstile in a circle, with a full can being moved away from the can filling station by means of one arm, the empty can immediately following by means of the second arm on the Can filling station is moved and the third arm is rotated in such a way that, during the next can change, it can take over the second can following the full can.
  • the disadvantage of this arrangement is the structurally complex structure with guideways for the full and empty cans.
  • a second concept relates to so-called linear can changers, in which, in particular, large-format cans (for example with a diameter of 1,200 mm) due to their width in the production direction Textile machine is moved linearly to the can filling station and, after filling, is moved further in the same direction or at an angle of, for example, 90°.
  • the disadvantage of this solution is that a very large movement path is required to move these cans.
  • Another disadvantage is that this type of can changer cannot be adjusted to smaller cans, since the can pushers in particular are designed for the respective can size.
  • a draw frame with a can drive for the linear conveying of sliver cans is known.
  • the sliver obtained at an outlet of the drafting system is deposited in the can, with the can to be filled being transported from an input side of the drafting system under the drafting system to the can filling station and, after filling, being ejected on the output side of the drafting system in the direction of sliver travel.
  • a third concept relates to can changers whose depositing head is arranged such that it can be moved back and forth between two cans.
  • the disadvantage of this concept is the mechanically complex structure and the fact that this concept cannot be used on textile machines with an integrated can filling station (e.g. draw frame, sliver winder, combing machine) in which the laying head is fixed.
  • the object of the invention is to counteract the aforementioned disadvantages.
  • a method for operating a can changer has at least two parking spaces, specifically one parking space and at least one intermediate parking space arranged behind the parking space in a direction along a predetermined movement path. Furthermore, the can changer comprises a can filling station arranged behind the last intermediate parking station in one direction and a drive section.
  • the drive section comprises a drive device and a can pusher which is operatively connected thereto in terms of movement.
  • the drive device is designed, upon actuation To move the can slide in such a way that the can slide moves a can in one direction from the parking space, either to the intermediate parking space or to the can filling space.
  • the method comprises a can changing process.
  • the can changing process has a first sub-process that is executed if there is only one can in the parking space or the intermediate parking space.
  • the first sub-process comprises a first step of actuating the drive device in such a way that the can pusher is moved from a starting position in one direction and the can is thereby moved in one direction onto the can filling station. Any full can on the can filling station is automatically pushed away from the can filling station and the storage locations. This is followed by a return movement step of moving the can pusher in another direction opposite to the one direction along the predetermined movement path to its starting position. If, instead, there are cans on both positions, the method includes a second sub-process.
  • the second sub-process includes a second step of actuating the drive device in such a way that the can pusher is moved out of the starting position in one direction and the can located on the parking space is moved in one direction to the intermediate parking space and automatically by means of the moved can can located on the intermediate parking space is moved in one direction to the can filling location.
  • any full can on the can filling station is automatically pushed away.
  • the aforementioned return movement step then takes place again.
  • This solution has the advantage that an empty can is always safely moved to the can filling station, regardless of how the parking spaces are occupied, provided there is a can on one of the parking spaces.
  • This also makes it possible to operate the can changer with more than two parking spaces and/or with cans of different diameters; operating parameters may have to be adjusted.
  • the method preferably has a can filling process which is carried out when there is a can to be filled at the can filling station and the can to be filled is still to be filled.
  • the can changing process is carried out when the can to be filled is full.
  • the can filling process preferably includes a step of determining when the can to be filled is full. This ensures that the can is always full before a can change.
  • Each of the aforementioned methods preferably also includes a determination step in which it is determined on which of the locations a can is located.
  • the can pusher can thus be moved faster, for example, as long as it is not pushing a can, i.e. it is being moved while it is idling.
  • the method has a notification process that is executed when the parking spaces are empty and a can located on the can filling station is full and/or the can filling station is empty.
  • the notification process includes a notification response.
  • the purpose of this process is to signal to a person that in the next can changing process no empty can can be moved to the can filling station because there is no empty can in any of the parking spaces or there is currently no can in the can filling station.
  • an operator it is possible for an operator to be able to place an empty can in good time, preferably in the parking space. Alternatively, however, the operator can also provide not to move any empty cans to a parking space.
  • the can filling station is emptied after the current can has been filled, so that cleaning work can be carried out, for example.
  • a safety reaction is also possible, for example in the form of an automatic (emergency) shutdown of the drive section and/or the textile machine which is coupled to the can changer or into which the can changer is integrated.
  • the can changing process is preferably only carried out if a can is to be filled and either the can filling station is empty or the can located on the can filling station is filled. This ensures that there is only a can on the can stand when a can filling process is pending. If there is no such request, the can filling station preferably remains empty, so that it is ensured that no can is moved onto the can parking station unnecessarily.
  • a can changer according to the invention is designed to be operated according to one of the aforementioned methods.
  • the can changer has the components specified at the outset, a can filling section and a can changing section.
  • the can filling section is set up to fill a can located on the can filling station.
  • the can changing section has the aforesaid drive section.
  • the can changing section is therefore set up to carry out the aforementioned can changing process.
  • the can changer preferably also has a guide section, by means of which the can pusher is guided along the movement path. This makes it possible to use cans with a smaller diameter with can changers that are actually intended for larger cans, and thus creates the possibility of being able to adapt one and the same can changer to cans of different diameters. This increases the number of identical parts, which has a favorable effect on the manufacturing costs.
  • the can pusher can be arranged or designed to be rigid, apart from being able to move along the movement path. Consequently, classic can slides can be used.
  • the parking space is preferably open on one side, which extends parallel or at an acute angle to the movement path in the area of the parking space.
  • An empty can can thus be placed on the parking place from the side of the can changer or at a preferably right angle to the path of movement of the can pusher. From a functional point of view, this keeps the overall length of the can changer to a minimum. This also promotes user-friendliness if the can changer is part of a draw frame, for example. Adjusting the empty can does not affect the arrangement of a creel.
  • the can changer also preferably has a can guide section.
  • the can guiding section is designed to guide cans between the intermediate storage place and the can filling place along the movement path in the area of these two places.
  • Each of the aforesaid can changers may have a sensor section.
  • the sensor section can be designed to detect the presence of a can at the storage location, the intermediate storage location and/or the can filling location. This can prevent the can changing process from being triggered unnecessarily.
  • the sensor section can be able to determine how far a can on the can filling station is filled and/or when the can on the can filling station is filled. In this way, an automatic can filling and can changing operation can be implemented without manual operations being necessary, apart from setting up new empty cans and transporting away the filled can.
  • non-contact sensors such as light barriers or mechanical sensors such as buttons can be used.
  • the sensor section can determine whether the can pusher is moving a can, this enables, for example, a controller of the drive section to automatically trigger the aforementioned notification or safety reaction.
  • a button can be used in such a way that it points in the direction of the can filling station and is actuated when a can is knocked against. If the sensor section is able to determine where the can pusher is located, this enables an optimal operation of the drive section.
  • the sensor section can be set up to determine whether the can slide and/or the drive section has reached at least a predetermined position as part of the movement of the can slide in the direction of the can filling station.
  • a button can be used at the respective position, which is actuated when the can pusher is pushed or moved past.
  • the sensor section can be set up to determine how many empty cans the can pusher moves. In the case of moving two empty cans, this makes it possible to operate the drive section only until the empty can closest to the can filling station has reached this same can filling station. In this case, the drive section only has to move the can pusher about half of its maximum movement path in the direction of the can filling station, ie it only has to be operated for about half that time at the same movement speed.
  • the sensor section is designed to determine when to initiate the reverse motion step. This prevents the can slide from being extended too far.
  • the drive device can have a pneumatic cylinder as drive means. This is a classic drive means and therefore inexpensive.
  • the can changer can also have a section or be coupled to one that is set up to cause the first or the second sub-process to be carried out when the can changing process is carried out. i.e. one and the same section of the can changer is able to carry out both sub-processes. This reduces the manufacturing costs and serves to simplify the construction of the entire can changer.
  • each of the aforementioned can changers runs along a straight line. This enables a particularly cost-effective and space-saving design of the can changer.
  • the can changer can easily be adapted to different can external dimensions and shapes.
  • a textile machine according to the invention has a processing section which is set up to process fiber material according to predetermined conditions. On the output side, the processing section is coupled to one of the aforementioned can changers.
  • the can changer can therefore be designed either as a part of the textile machine or as a downstream, separate machine part.
  • the can changer is preferably integrated into the textile machine. This keeps the overall dimensions of the textile machine within limits.
  • the movement path of the can changer When the movement path of the can changer is rectilinear, the movement path in each of the aforementioned textile machines preferably runs along a fiber processing direction of the textile machine from the processing section to the can filling section. As a result, the width dimensions of the textile machine in particular are hardly increased or not increased at all transversely to the processing direction.
  • figure 1 shows a drawing frame 1 with a can changing section 20 according to an embodiment of the invention.
  • Route 1 is unregulated here executed and includes a trained in a known manner, not designated stretch section.
  • the drafting section comprises a drafting system hood 18, which covers a drafting system lying underneath and a can depositing device. Both are known and will not be described further.
  • an infeed table 15 is arranged, via which slivers from cans typically enter the drafting system via a creel.
  • hood 18 On the side of the drafting system hood 18 there are side hoods 17 which cover other components of the draw frame 1 such as drive belts, deflection rollers of the drafting system, etc.
  • the draw frame 1 preferably comprises a housing 16, in which a suction channel for the drafting system and a control of the draw frame 1 are housed, for example.
  • the stretching section is arranged in a known manner on a plate 3 of the draw frame 1 or partially integrated into it (for example in the form of the depositing plate of the can depositing device).

  • the sensor 9 can Include a light barrier whose detection beam runs along the axis of rotation of the turntable 7 in the region of the edge of the illustrated can 4 facing away from the empty cans 5 .
  • the detection beam preferably runs in an area outside of a line along the processing direction V, which intersects the center of rotation of the turntable 7 . This ensures that the detection beam is arranged in an area where two immediately adjacent cans 4, 5 do not touch one another when they are moved, as in FIG figure 2 represented by a digit 14.
  • the signal from the sensor 9 for detecting the presence of a can 4 on the turntable 7 is ignored until it sends a signal that a can 4 is not present on the turntable 7.
  • the pot 4 is held in position on the turntable 7 by two, preferably four, pivoted levers 13, 13.
  • the can pusher 22 shifts the can 4, 5 closest to it here in the processing direction V and pushes the can/s 4, 5 possibly arranged behind it with it.
  • a mechanical switch is arranged in the base plate 6, which protrudes so far from the base plate 6 that it can be safely actuated by a can 4, 5 as soon as it is in the can-filling position on the turntable 7 (i.e. on the can-filling station 12).
  • the switch can also be positioned in such a way that it remains permanently actuated when there are several cans 4, 5 when they are moved.
  • a controller for the pneumatic cylinder 21 only needs to detect when the can pusher 22 has been displaced by one can position. If the operation of the switch has not been canceled in the meantime, a pot 4 has previously been on the intermediate parking space 11, which is now on the can filling station 12. This means that the pneumatic cylinder 21 can be switched off and the can pusher 22 can move to the starting position according to Figure 1 or figure 2 be moved back.

  • the guide walls 24 are fixed here to the base plate 6 via brackets 25 and are designed in such a way that the can pusher 22 can be moved safely.
  • figure 4 shows the can changing section 20 in two operating states in the case of three existing cans 4, 5, 5.
  • the can 4 is full and must be replaced by an empty can 5.
  • the can pusher 22 in the in Figure 4a shown starting position by means of the pneumatic cylinder 21 in the direction of the turntable 7 moves. If the sensor 9 (not shown here) has been used to detect that the can 5 has left the can filling station 12 and a new can 4 has been moved onto the turntable 7 (final operating state according to Figure 4b ), the pneumatic cylinder 21 is actuated, the can pusher 22 back into the in Figure 4a return to the starting position shown.

If the can slide 22 is moved to the maximum and there is no intermediate signal from the sensor 9 that there was no can 4, 5 in its detection range at any time during the movement of the can slide, it is clear that there is no empty can 5, so that a can is filled is simply impossible. i.e. Using a simple sensor system, draw frame 1 can be automatically shut down in an emergency to avoid unnecessary processing of fiber material in the drafting system and thus waste.
  • the right lever 13 can be designed in such a way that it actuates or releases a preferably mechanical switch as a sensor when the right lever 13 is moved from the position shown in figure 2 swing-out position shown due to a passing can 5 upwards in figure 2 is swung in.
  • the invention is not limited to the above embodiment.
  • the sensor section can be set up to detect when the piston of the pneumatic cylinder 21 has reached an intermediate extended position, which corresponds to a position in which the can pusher 22 would have pushed a can 5 onto the intermediate parking space 11, and/or has reached a final extended position which corresponds to a position in which the can pusher 22 would have pushed a can 5 onto the can filling station 11 .

  • a button for example, which is actuated (temporarily) by the can pusher 22 moved past or the connection to the piston of the pneumatic cylinder 21, is suitable as a detection sensor.
  • the controller determines which path the piston has already covered. If the detection sensor is also arranged in such a way that it can also detect a can 5 located on the respective location 10, 11, separate sensors for locations 10-12 can be omitted. In extreme cases, a single sensor is sufficient for the intermediate storage location 11: If the detection sensor has not been triggered beforehand, i.e. before the can slide 22 is detected as the can slide 22 moving past, it is clear that the can slide 22 is not moving a can 5 onto the can filling station 12. This enables the aforesaid notification response and/or security response; in any case, the piston is moved back again.
  • the detection sensor has only been triggered once previously, it is clear that the can pusher 22 is currently only moving one can 5 . In that case, the piston must be moved to its final extended position. If the final extension position corresponds to the maximum stroke of the piston, no additional sensor is required. When the piston has reached its final extended position, the piston is moved back again. If the detection sensor has already triggered twice beforehand, it is clear that the can pusher 22 is currently moving two cans 5 . This means that the can filling station 12 is already occupied by a new empty can 4, and the piston 22 is moved back again before it is detected by the detection sensor. Whether the detection sensor now detects a can 5 or the piston or can slide 22 (indirectly) can be determined on the basis of the movement speed and the elapsed time from the start of operation of the pneumatic cylinder 21 to the respective triggering of the detection sensor.
  • a collision sensor is provided on the can pusher 22, by means of which it can be detected when the can pusher 22 strikes a can 4, 5. In the simplest case, this is a button. However, contactless proximity sensors are also available. If the collision sensor detects bumping against a can 4, 5 and the piston has not yet reached its final extended position, this is a signal for the controller to only move the piston further out by the distance that corresponds to the movement of a can 5 onto the nearest place 11, 12 corresponds. If the piston is already fully extended when such a detection is made, this is the signal for the controller that no empty can 5 is present, so that an advisory reaction and/or a safety reaction can take place. With the presence of the collision sensor, sensors for monitoring the storage locations 10, 11 and possibly also the can filling location 12 with regard to the respective presence of a can 4, 5 could be omitted.
  • the pneumatic cylinder 21 can be replaced by any other drive means, such as an electric motor, possibly with a connected gear.
  • the sensor system for monitoring the extended position of the piston would be replaced by a corresponding sensor system.
  • a rotary encoder can be used, the line or code disk of which is arranged in a rotationally fixed manner, for example, on the output shaft of the electric motor.
  • the number of can parking spaces 10, 11 in the can changing direction in front of the can filling station 12 can vary, is at least 2 and can also be reduced to one (one) parking space with one and the same design of the can pusher construction.
  • the control can be designed to be adaptable in such a way that the movement path of the can pusher 12 for the can changing process can be adapted to the respective diameter of the cans to be filled and can even be changed during operation, as long as the guide walls 24 permit this.
  • the guide walls 24 can be arranged to be displaceable, for example via grooves on the base plate 6, so that the drawing frame 1 can also be switched over to cans with a larger diameter.
  • the brackets 25 can be attached to the columns 2 via spacers, for example.
  • the parking spaces 10, 11 can also be monitored.
  • a sensor system can be provided, which monitors the fill level of the currently filled can 4 . This makes it possible to recognize when the can 4 has to be exchanged for an empty can 5, so that the entire process can take place fully automatically.
