Definitions

the present invention relates to a method for feeding a sliver end of a sliver deposited in a can to a spinning position of a spinning machine.
the spinning machine has a multiplicity of spinning stations arranged next to one another with cans placed underneath in at least one row.
a robot with a belt gripper grips the end of the belt and feeds it to a spinning station to be fed.
a sliver end of a sliver placed in a can is attached to a spinning station of the spinning machine to be fed, whereby for feeding the end of the band, the band gripper is equipped with elements for gripping the end of the band and feeding it to the spinning station.
a maintenance device for fiber-processing textile machines with a plurality of work stations which has a handling device for manipulating fiber sliver.
the handling device detects the sliver with the aid of a suction tube and a mechanical and / or pneumatic holding device for the sliver.
the suction pipe has a flattened suction pipe mouth with which a sliver end hanging over a can can be sucked in over a relatively wide area.
the disadvantage here is that if the sliver end does not hang over the edge of the can in the area of the workstation to be supplied, the wide suction tube mouth cannot find the sliver end either.
a manipulator which has at its free end a suction nozzle for receiving and fixing the beginning of a sliver.
the sliver is attached to the jug in a clamp, so that the end of the sliver can always be found at a defined position.
the manipulator can thus specifically reach this point and detect the sliver.
the disadvantage here is that each jug must be equipped with a clamp and the jug must be set up in a certain direction of rotation on the machine so that the manipulator can find the end of the belt.
the DE 43 21 367 A1 discloses an apparatus for automatically applying a sliver to a feed device of a textile machine.
the sliver is gripped and fed to the spinning device. Gripping the sliver is simplified by the use of so-called long cans, which are only under a single spinning station and have a width which is less than the width of the spinning station itself. This limits the area in which the sliver end can be located.
long cans are more expensive to buy than round cans and require special machines with which the sliver can be placed in the long cans.
the object of the present invention is therefore to provide a method and a spinning machine with which the disadvantages described can be avoided.
the method according to the invention serves to feed a sliver end of a sliver deposited in a can to a spinning position of a spinning machine.
the spinning machine has a multiplicity of spinning stations arranged next to one another with cans placed underneath in at least one row.
the cans are preferably round cans.
a robot grips the end of the belt with a belt gripper and feeds it to a spinning station to be fed.
the end of the tape becomes at least one of the areas adjacent spinning positions of the spinning position to be fed, preferably in the area of the spinning position to be fed and additionally at least one of the spinning position adjacent to this spinning position, are sought and picked up by the belt gripper.
the strip end is then fed to the spinning station to be fed.
the feed takes place in that the sliver is introduced into a feed of the spinning station equipped with a feed roller.
the feed roller can be driven, whereby the spinning operation is resumed when the sliver is inserted and the sliver is continuously drawn into the spinning station.
round cans due to their large diameter, extend along the width of two spinning stations. This makes it possible that when the robot is positioned in relation to a spinning station, the sliver end can be found either in the area of this spinning station to be fed or in the area of the adjacent spinning station. With the aid of the method according to the invention, it is now ensured that the end of the sliver can be reliably grasped, since the sliver gripper searches for the sliver at least in the area of the adjacent spinning station, preferably also in the area of the spinning station to be fed.
the robot is moved along the spinning machine and positioned in relation to the spinning station to be fed or to the spinning station adjacent to it.
the robot can be precisely assigned to this spinning machine by means of a running rail installed on the spinning machine.
the robot usually not only does the feeding of the sliver to the spinning station, but also other activities, which include, for example, attaching a thread, cleaning the spinning station or changing bobbins at the spinning station.
the robot can be designed as a can transport vehicle which travels along one or more spinning machines and in addition to feeding the sliver to the spinning station, the spinning cans are also replaced, ie the empty spinning can is replaced by a full spinning can.
the robot travels along several spinning machines similar to a can transport vehicle and is essentially only responsible for feeding the sliver to the spinning station.
the robot in the event that it has been positioned in relation to a spinning station adjacent to the spinning station to be fed, together with the sliver taken up and before the sliver is fed into the feed of the spinning station into a position in front of the spinning station to be fed becomes.
the robot is able to take up the sliver directly on the full can, which is intended for further spinning. Gripping the sliver is particularly easy for the robot in this positioning at the adjacent spinning station, since the robot can carry out the same movements for both adjacent spinning stations.
the robot has gripped the sliver, it positions itself exactly in front of the spinning station to be fed and is therefore able to insert the sliver end very precisely into the feed of the spinning station.
the belt gripper is advantageously moved relative to the robot along the spinning machine to an adjacent spinning station and / or to a can set up in a second row.
the belt gripper is thus able to search for the sliver in a predetermined area, even when the robot is stationary, which can be larger than the actual area which the belt gripper can actually reach.
the robot it is possible, if not absolutely necessary, for the robot to be positioned immediately at the spinning station to be fed and for a suitable movement of the belt gripper to find, grasp and in the fiber sliver in the area of the neighboring spinning station or in the second row of the cans set up introduces the feed to the spinning station.
the sliver gripper can pick up the sliver simultaneously from several possible positions at adjacent spinning positions. It is thus possible for the belt gripper to search for the fiber sliver both at the spinning station to be fed and at adjacent spinning stations arranged to the left or right of this spinning station and to grasp it there.
the belt gripper searches for the sliver on the top of the can and / or on the circumference of the can. If the ribbon gripper is looking for the sliver on the top of the can, it is also advantageous if the end of the sliver is placed, for example, like a string on the top of the can. This defines a defined area in which the ribbon gripper can locate the sliver end. If the sliver is on the circumference of the jug, it is possible that the sliver is fixed there at the jug at a defined position or at least hangs out of the jug at this position. This also makes it easy for the tape gripper to find and grasp the tape end quickly.
a spinning machine has a large number of spinning stations arranged next to one another and a robot on which a belt gripper is arranged. At least one row of cans with a sliver is present under the spinning positions.
the sliver gripper is equipped in such a way that it can grip the sliver end and feed it to the spinning point.
the belt gripper is designed and / or arranged on the robot such that the belt end is in an area of at least one spinning station which is adjacent to the spinning station to be fed, preferably in the area of the spinning station to be fed and additionally at least one of the spinning station adjacent to this spinning station, record and then the feed Can feed spinning station.
the belt gripper is thus able to locate the end of the belt safely and to feed it to the spinning point at which the sliver is missing, so that the spinning process can be continued at this spinning point.
the invention is based on the consideration that in the case of round spinning cans which have a diameter which corresponds approximately to the width of two spinning positions, the fiber sliver either lies in the area of the spinning position to be fed or else in the area of the adjacent spinning position and is easier to find there . It is particularly advantageous if the robot is designed such that it finds the end of the sliver at only a single spinning position. This increases the likelihood of finding the sliver. As a result, however, it may also be necessary for the robot to be positioned at the adjacent spinning position in order to be able to find the end of the belt.
the robot can be moved together with the end of the strip into the correct position in front of the spinning station to be fed and can then feed the end of the strip to the feed of the spinning station.
the robot can also be advantageous if the robot is already positioned correctly and immediately in front of the spinning station to be fed and the belt gripper is there to search for and detect the end of the belt. If the end of the strip is located between the two spinning positions, depending on the design of the strip gripper, it may be advantageous for the robot to be positioned either at the adjacent or at the spinning point to be fed in order to find the end of the strip.
the robot is advantageously arranged stationary at the spinning station and / or arranged to be movable on a can changer and / or on the spinning machine along the spinning machine, a solution for feeding the end of the strip can be provided individually, depending on the productivity of the machine.
the robot is stationary on the Spinning station is arranged, it is necessary that each of the plurality of spinning stations on the spinning machine has a robot that can introduce the sliver into the feed. It is advantageous here that a mobile robot does not have to be requested first and, accordingly, no waiting time is required until the sliver can be attached.
the feeding of the sliver or at least a preparation for feeding the sliver to the feed of the spinning station can be carried out. If necessary, the individual spinning station can then grip this sliver or pull it into the feed and continue the spinning process.
the robot on the spinning machine can be moved along this spinning machine. This means that the robot is guided on a rail of the spinning machine, for example, and patrols along the spinning machine. After the can has been changed, the robot drives along the spinning machine to the spinning station to be fed and carries out the feeding of the sliver. In this case, it is particularly advantageous that the exact positioning of the robot in front of the spinning station can also be used for further maintenance activities, for example feeding a thread or cleaning the spinning station, at the spinning station.
the robot can be moved along several spinning machines.
the robot can thus switch from one spinning machine to another spinning machine. Waiting times of the robot until a further maintenance need or sliver change has to be carried out can be kept short.
the belt gripper is designed to be movable relative to the robot along the spinning machine to an adjacent spinning station and / or to a can set up in a second row. This makes it possible for the belt gripper to move in front of or next to the one to be fed when it is stationary.
the spinning position of the robot is in a larger area than the ribbon gripper would allow, the fiber ribbon end can search and grasp. A repositioning of the robot after finding the end of the belt in order to feed it to the spinning station to be fed can thus be avoided.
the sliver gripper it is able to pick up the sliver simultaneously from several possible positions at adjacent spinning positions.
a particularly advantageous embodiment of the belt gripper consists, for example, of a very wide belt gripper which picks up both the area of the spinning station to be fed and the neighboring spinning station and at the same time searches for the end of the band. It is advantageous here if the belt gripper has a width in order to be able to grasp the end of the belt at at least two adjacent spinning positions.
the tape gripper has a suction unit which is suitable for sucking in the tape end, the tape gripper can simultaneously search for the sliver end in a larger area than with a mechanical gripper.
the belt gripper has a blowing unit for feeding the end of the belt into the feed of the spinning station. It is very easy and reliable to insert the end of the strip into the feed of the spinning station.
FIG. 1 shows a side view of a spinning machine 1 before gripping a strip end 2.
the spinning machine 1 has a plurality of spinning positions 3, which are arranged side by side.
a machine frame 4 is arranged at each of the two ends of the spinning machine 1.
Each spinning station 3 has a spinning box 5 and a bobbin 6, on which a yarn 7 is wound.
the yarn 7 is spun in the spin box 5 from a sliver 8 which is fed to the spin box 5 from a can 9.
a feed 11 which consists of at least one driven roller, the fiber sliver 8 is actively fed to the spin box 5.
the sliver 8 is guided on the way between the can 9 and the spin box 5 through a loop catcher 10, which is intended to prevent loops in the sliver 8 from being formed when the sliver 8 is removed from the can 8, which could lead to a break in the sliver.
the can 9 is exchanged for a full can 9.
the band end 2 of the sliver 8 contained therein hangs, for example, as shown in the can 9a, over the upper edge of the can 9a.
the sliver 8 is missing at the spinning point 3a to be fed, at which the sliver 8 is to be attached, in order to be able to continue the spinning operation.
the neighboring spinning station 3b continues to receive its sliver 8 from a can 9b, which, not visible, is arranged behind the can 9a in a second row.
the band end 2, which hangs over the edge of the can 9a can either be located in a region Ba below the spinning station 3a to be fed or in the region Bb below the adjacent spinning station 3b.
a robot 12 is located in front of the adjacent spinning station 3b.
the robot 12 can be moved along the spinning machine 1 in accordance with the double arrow V. If a spinning station 3 reports to a control device that there is a need for maintenance, for example a missing sliver 8 at a specific spinning station 3, the robot 12 is stopped at this spinning station 3, here the spinning station 3a to be fed or the neighboring spinning station 3b and starts its maintenance work. In the representation of the Figure 1 the robot 12 thus stands in front of the adjacent spinning station 3b.
the belt gripper 14 is a suction pipe which is able to suck in the belt end 2.
the belt gripper 14 can be pivoted according to the double arrow S, so that it can move the sucked-in end 2 of the belt in the direction of the feed 11 for feeding the end of the band 2 to the spinning station 3a.
the belt gripper 14 can of course also be designed differently than by a pneumatically operated suction pipe.
a mechanical gripper is also possible, which grips the band end 2 on the can 9a.
the robot 12 is located in front of the adjacent spinning station 3b.
the belt gripper 14 can find and grip the belt end 2, which can be located in the region Ba or Bb, for example by the pivoting movement S. Because the robot 12 is positioned at the adjacent spinning station 3b, the belt gripper 14 can grip the belt end 2, in particular in its area Bb. But even if the belt end 2 is in the area Ba of the spinning station 3a to be fed, the belt gripper 14 is able to grasp this belt end 2.
Figure 2 shows the spinning machine Figure 1 when feeding the tape end 2 at the spinning station 3a.
the robot 12 is thus moved according to arrow Va in the direction of the spinning station 3a to be fed and positioned there.
the belt gripper 14 has gripped the end of the belt 2 and leads it to the spinning station 3a to be fed.
the fiber sliver 8 or the sliver end 2 is moved to the feed 11 of the spinning station 3a to be fed and can be introduced into the feed 11 there, for example by a pressure surge from the sliver gripper 14.
either the sliver gripper 14 can have devices which thread the sliver 8 through the sling catcher 10, or the sling catcher 10 is designed such that it is, for example, by a lateral insertion of the sliver 8 into the sling catcher 10, can take up its function.
the robot 12 leaves the spinning station 3 a to be fed and carries out further maintenance work on other spinning stations 3.
the robot 12 is first positioned in the area of the adjacent spinning station 3b, searches for the end of the tape 2 at least in the area Bb of the adjacent spinning station 3b, but also here in the area Ba of the spinning station 3a to be fed, and picks up the end of the tape 2.
the robot 12 then moves in front of the spinning station 3a to be fed, positions itself there and inserts the end of the strip 2 into the feed 11 of the spinning station 3a to be fed.
the belt gripper 14 is designed such that, on the one hand, it searches for and grips the end of the belt 2 in the region Bb of the adjacent spinning station 3b, but then, without further movement of the robot 12, for example by an articulated or telescopic movement of the Belt gripper 14, the belt end 2 into the feed 11 of the spinning station 3a to be fed.
FIG. 3 shows the spinning machine 1 before gripping a strip end 2 for feeding at another spinning station 3, which in turn is referred to here as the spinning station 3a to be fed.
the robot 12 is in this embodiment positioned in front of the spinning station 3a to be fed.
the belt gripper 14 is able to grasp the belt end 2 hanging out of the can 9a and located in the region Bb of the adjacent spinning station 3b.
the tape gripper 14 pivots, as in FIG Figure 4 shown, upwards in the direction of the feed 11 and introduces the tape end 2 into the feed 11 either independently or with the aid of further insertion elements.
FIG Figure 4th shows, it is not necessary here that the robot 12 has to be repositioned after finding the end of the strip 2 in order to feed the end of the strip 2 into the feed 11 of the spinning station 3a.
Figure 5 shows an embodiment of a robot 12 with a belt gripper 14 that is movable relative to the robot 12.
the belt gripper 14 is moved together with the belt attachment device 13 in the horizontal direction RH to the robot 12.
a swiveling movement S of the band gripper 14 it is very easily possible for the band end 2 in the region Bb of the neighboring one Spinning station 3b and possibly additionally in the area Ba of the spinning station 3a to be fed is searched for and found.
the belt gripper 14 is operated pneumatically. According to arrow Ls, the belt gripper 14 is able to suck the belt end 2 into the belt gripper 14. To feed the sliver 8 or sliver end 2 into the feed 11 of the spinning station 3a, the suction flow can be switched over to a compressed air flow and thus blow the sliver end 2 into the feed 11 according to arrow Lb. The feeding of the tape end 2 or fiber sliver 8 at the spinning station 3a to be fed can thereby take place very reliably.
FIG. 6 shows an embodiment of a robot 12 with a wide belt gripper 14.
the belt gripper 14 has a width B, through which it is able to grasp a belt end 2 both in the area Ba and in the area Bb.
the air flows L are in accordance with Figure 5 Not provided at the end of the tape gripper 14, but along the tape gripper 14 and suck in the sliver 8 transversely to the tape gripper 14.
the tape attachment device 13 together with the tape gripper 14 can be moved vertically according to the double arrow RV relative to the robot 12. It may be sufficient for the belt gripper 14 to be arranged stationary on the belt attachment device 13, that is to say not pivotable.
FIG. 7 shows two spinning stations 3a and 3b with a stationarily arranged belt gripper 14.
the belt gripper 14 or the belt attachment device 13 is firmly attached with respect to the two spinning stations 3a and 3b.
the belt gripper 14 By swiveling the belt gripper 14 according to double arrow S, the belt gripper 14 is able to grasp a belt end 2 both in the region Ba and in the region Bb and to feed it to the spinning station 3a.
the belt gripper 14 can Feed the tape end 2 either to the spinning station 3 arranged on the left side of the can 9 or to the spinning station 3 arranged on the right side of the can 9.
the tape attachment device 13 can also be designed to be vertically and horizontally displaceable according to the double arrow RV and additionally according to the double arrow RH.
Figure 8 shows a top view of several spinning stations 3 with rows of cans 9 arranged underneath.
the cans 9 of the first row R1 protrude from the spinning stations 3, while the cans 9 of the second row R2 are arranged entirely below the spinning stations 3.
no sliver 8 is inserted at two spinning positions 3a.
the corresponding cans 9a are located both in the first row R1 and in the second row R2.
the band end 2 of the can 9a shown in the second row R2 is deposited like a string over an upper side 16 of the can 9.
a belt gripper 14, not shown here, can be picked up by a swiveling movement which, contrary to the representation of the previous figures, does not allow movement of the belt gripper 14 in front of the spinning stations 3 but under the spinning stations 3. As soon as the band end 2 is gripped on this upper side 16, it is pulled together with the band gripper 14 under the spinning stations 3a, 3b and attached to the spinning station 3a.
the band end 2 is placed hanging over the edge of the can.
the belt gripper 14 can grip the belt end 2 around the circumference 15 of the can 9a and feed it to the spinning station 3a to be fed.
the band end 2 lying over the top 16 can also be in the case of a can 9a of the first row R1 or that over the circumference 15 the tape end 2 depending on the can 9a can also be presented in the case of a can 9a to be fed in the second row R2.
