Definitions

  • the present invention relates to a device for pneumatically feeding fiber material to a plurality of textile machines, which are designed as cards or cards, by means of filling shafts upstream of the textile machines, which are connected to a common pneumatic transport line.
  • the present invention further relates to a method using the device.
  • From the DE 34 42 942 A1 is a device for pneumatically feeding a number of cards by means of reserve shafts upstream of the individual cards, which are connected to a common pneumatic transport line and to which feed shafts are connected downstream, is known.
  • the transport line is connected via a material transport fan to an upstream fiber processing machine, e.g. B. precision opener, connected.
  • the object of the present invention is to provide a device or a method in order to prevent the transport line and the faulty textile machine from clogging in the event of a fault in a textile machine.
  • the solution to the problem is a device for pneumatically feeding fiber material to a plurality of textile machines, which are designed as cards or cards, by means of filling shafts upstream of the textile machines, which are connected to a common pneumatic transport line running above the filling shafts, the transport line for connection to the filling shafts between their line entrance and their line end each has a bottom opening, wherein a fiber processing machine can be connected to the line entrance via a material transport fan and the line end is permanently closed, stated, in a transport direction between two of the bottom openings, which are arranged adjacent to one another are, a closure member coupled to an actuator is arranged, wherein the respective closure member borders on an upstream bottom opening of the two bottom openings arranged adjacent to one another and enables flow through the transport line in an open position and prevents it in a closed position, and wherein a control unit with the Textile machines and the actuators are communicatively connected and configured, in the event of a malfunction at least one in the transport direction of the last textile machine, the closure element closest up
  • the buyer for the pneumatically fed fiber material is missing in the strand end of the transport line, which is formed by the permanently closed line end.
  • the advantage is that by closing the closure member closest upstream of the faulty textile machine, clogging of the strand end of the transport line and the filling shaft of the faulty textile machine is prevented without impairing the operation of the upstream or upstream textile machines.
  • Another advantage is that after the fault has been eliminated, which may have been caused, for example, by a defect in the textile machine, a belt break or even scheduled maintenance for which the textile machine has to be stopped, the textile machine can start up again more quickly.
  • the closure element closest upstream of the row of faulty, last textile machines can be closed in order to prevent clogging in the end of the strand.
  • the operation of the last textile machine is undisturbed and only one of the front or middle textile machines is disturbed, none of the locking elements are moved into the closed position in order not to disrupt the operation of the last textile machine.
  • the upstream closure elements as in the DE 34 42 942 A1 proposed to be set in positions between the open position and the closed position.
  • Up to eight cards are preferably connected to the transport channel, which is closed at the end.
  • the solution to the problem is also through a device for pneumatically feeding fiber material to a plurality of textile machines, which are designed as cards or cards, by means of filling shafts upstream of the textile machines, which are connected to a common pneumatic transport line running above the filling shafts, whereby the Transport line for connection to the filling shafts each has a bottom opening, the bottom openings being between a first line inlet, which is connected to a first fiber processing machine via a first material transport fan specifying a first transport direction, and a second line inlet, which is connected via a second material transport fan specifying a second transport direction a second fiber processing machine is connected, are designed, wherein in both transport directions downstream of each bottom opening there is a closure member coupled to an actuator, which independently of one another enables flow through the transport line in an open position and prevents it in a closed position, and wherein a control unit with The textile machines and the actuators are communicatively connected and configured to hold at least one of the two closure members arranged between two adjacent bottom openings for
  • the device according to the invention with the two material transport fans results in the same advantages as those described in connection with the device according to the invention with the one material transport fan, so that abbreviated reference is made here to the above description.
  • the transport line is divided into two line sections by the at least one closure element, which is held in the closed position.
  • the textile machines can be fed with fiber material from two different lines within the spinning mill.
  • a first group of textile machines can be connected to the first line section and a second group of Textile machines can be connected to the second line section.
  • the two closure members which are arranged between the two adjacent bottom openings, are held in the closed position for dividing the transport line into the two line sections. This reduces the size of the dead-end line end, so that less fiber material can build up.
  • the division by means of the at least one closure element enables the number of textile machines per group to be adjusted. Another advantage is that the line sections can be fed with different fiber material.
  • the division into the two line sections leads to two strand ends.
  • the control unit closes the closure element closest upstream of the faulty textile machine, so that the operation of the upstream textile machines is not impaired.
  • up to eight cards per line section are connected to the transport channel.
  • the closure elements can be designed as flaps, sliders or the like.
  • the transfer from the open position to the closed position, and vice versa, can be done by a pivoting movement around the horizontal or vertical axis.
  • an axial displacement is also possible.
  • the respective closure element is designed as a plate-shaped shut-off valve, which can be pivoted in the transport line about a particularly vertical pivot axis from the open position to the closed position and vice versa by means of the actuator.
  • a flap adjustment can be easily implemented in the transport channel.
  • a distance between the respective bottom opening and the adjacent closure element in the closed state is a maximum of 500 millimeters.
  • the respective distance is at least 20 millimeters. This, on the one hand, provides sufficient installation space in the transport channel to accommodate the respective adjustable closure element, and on the other hand, it is ensured that the end of the strand and the at least one faulty textile machine do not become clogged.
  • the actuators can include pneumatically operated pressure cylinders.
  • the control unit can be a higher-level control unit, a so-called line controller, to which, among other things, the textile machines are connected.
  • the line controller can monitor and control the operation of the device.
  • the control unit can receive signals about the activity states of the individual textile machines.
  • the line controller can be connected to subordinate control units of the textile machines. These can transmit the fault, for example “in service”, “belt break” or the like, to the line controller.
  • the line controller can instruct the closing element closest upstream of the faulty textile machine to close directly after receiving the fault message or after a defined waiting period. The latter can be advantageous, for example, in the event of a reported belt break.
  • the Figure 1 shows a device for pneumatically feeding fiber material to a plurality of textile machines 1 according to a first embodiment of the present invention.
  • the textile machines 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, here as an example six, are designed as cards and lined up next to each other on a hall floor 2.
  • the textile machines 1.1, 1.2, 1.3, 1.4, 1.5, 1.6 have upstream filling shafts 3, which are connected to a common pneumatic transport line 4 running above the filling shafts 3.
  • the transport line 4 has a line inlet 5 to which a fiber processing machine 6 is connected via a material transport fan 7.
  • the transport line 4 is permanently closed at a line end 8 remote from the line inlet 5.
  • the material transport fan 7 pneumatically conveys the opened fiber material through the transport line 4 in a transport direction directed towards the end of the line 8.
  • the transport direction is in the Figure 1 illustrated with the arrow A.
  • Bottom openings 9 formed in the transport line serve as line outlets, to which the filling shafts 3 of the textile machines 1.1, 1.2, 1.3, 1.4, 1.5, 1.6 are connected.
  • the fiber material flows through the bottom openings 9 are in the Figure 1 indicated by arrows, whereby for the sake of clarity only the first of, here, five fiber material streams in the transport direction A is provided with the reference number F.
  • the bottom openings 9 are recesses in the bottom of the transport line 4 and can, for example, have a rectangular cross section.
  • the bottom openings 9 are shown with dashed lines in FIG.
  • a flap 10 is arranged in the transport direction A between two of the floor openings 9 arranged adjacent to one another.
  • the respective flap 10 borders on the upstream bottom opening 9 of the two bottom openings 9 and can be pivoted about a vertical pivot axis 12 between an open position and a closed position by means of a coupled actuator 11.
  • the fiber material can pass through the respective flap 10, so that flow through the transport line 4 is possible.
  • the closed position the transport line 4 is blocked downstream of the closed flap 10.
  • the flaps 10 are designed as plate-shaped shut-off flaps and are spaced at a distance of less than 500 millimeters from the floor opening 9 closest upstream.
  • the actuator 11 of the respective flap 10 comprises a pneumatically operated pressure cylinder, which is controlled via a connected control unit 13.
  • the control unit 13 can be a line controller that monitors and controls the operation of the device. During operation, the control unit receives 13 signals about the activity states of the individual textile machines. For this purpose, the control unit 13 can be connected to controls (not shown) of the textile machine 1.1, 1.2, 1.3, 1.4, 1.5, 1.6. When all six textile machines 1.1, 1.2, 1.3, 1.4, 1.5, 1.6 process the fiber material and are in regular operation, all flaps 10 are in the open position.
  • the closed position of at least one of the flaps 10 only needs to be approached if at least the last textile machine 1.6 in the transport direction A is disturbed and is therefore unable to act as a buyer for the fiber material, as described in detail below.
  • a first scenario is shown in which the operation of the last textile machine 1.6 in the transport direction A is disrupted.
  • the malfunction can be caused, for example, by a sliver tearing of the sliver made from the fiber material or due to service purposes.
  • This can lead to blockage of the strand end 14 and the filling shaft 3 of the last textile machine 1.6 within a very short time.
  • an operator often does not have enough time to close the flap 10 closest upstream before the strand end 14 becomes blocked.
  • the control unit 13 controls the actuator 11 of the flap 10, which is arranged upstream of the last textile machine, in order to move it into the closed position.
  • the closed flap is provided with the reference number 10.c.
  • the control unit 13 can be connected to a control of the last textile machine 1.6.
  • the textile machine 1.6 can have at least one sensor, for example a belt sensor, a speed sensor or the like, in order to have one To be able to detect a belt break, a standstill, etc.
  • the other textile machines 1.1, 1.2, 1.3, 1.4, 1.5 can also include such a control and sensors coupled to the control unit 13. Additionally or alternatively, the actuating drives 11 can be controlled manually by the operator himself, for example via an operating unit connected to the control unit 13.
  • FIG 2 is a second scenario of the device from the Figure 1 shown, in which the operation of the last two textile machines 1.5, 1.6 in the transport direction A is disrupted. It can be seen that the flap 10.c arranged closest upstream of the two last textile machines 1.5, 1.6 arranged immediately one behind the other in the transport direction A, i.e. a group of the last textile machines 1.5, 1.6 in trouble, is closed.
  • the last flap 10 in the transport direction A which lies in the blocked strand end 14 in front of the textile machine 1.6, can, however, be in the open position, as shown here, or closed.
  • the Figure 3 shows a device for pneumatically feeding fiber material to a plurality of textile machines 1.1, 1.2, 1.3, 1.4, 1.5, 1.6 according to a second embodiment of the present invention, which is the one from the Figures 1 and 2 largely corresponds, so that reference is made to the above description with regard to the similarities.
  • the same or modified details are given the same reference numbers as in the Figures 1 and 2 .
  • the difference lies in the loading of the transport line 4, which can take place from two opposite transport directions.
  • the first transport direction is indicated by arrow A and the second transport direction is indicated by arrow B.
  • the transport line has two line inputs 5.1, 5. 2.
  • the first line inlet 5.1 is connected to a first fiber processing machine 6.1 via a first material transport fan 7.1 which specifies the first transport direction A.
  • the second line inlet 5.2 is connected to a second fiber processing machine 6.1 via a second material transport fan 7.2 which specifies the second transport direction B.
  • the device can therefore be connected to two different opener or cleaner lines in the cleaning room.
  • the bottom openings 9 of the transport line 4 formed between the line inputs 5.1, 5.2 and to which the filling shafts 3 of the textile machines 1.1, 1.2, 1.3, 1.4, 1.5, 1.6 are connected serve as line outlets.
  • the two flaps 10.1d, 10.2d which lie between two adjacent bottom openings 9, are in their closed position.
  • the flaps closed for dividing are provided with the reference numbers 10.1d, 10.2d.
  • the flaps 10.1d, 10.2d thus represent the temporary line ends 8.1, 8.2 of the respective line section 15.1, 15.2. It can be seen that, for this purpose, the middle flaps 10.1d, 10.2d are closed, purely as an example. so that three of the textile machines 1.1, 1.2, 1.3 or 1.4, 1.5, 1.6 are connected to each line section 15.1, 15.2.
  • another pair of adjacent flaps 10 could also be closed in order to provide a division other than the uniform distribution of the textile machines among the line sections 15.1, 15.2 shown.
  • the control unit 13 keeps the flaps 10.1d, 10.2d for dividing the transport line 4 closed and, in the event of malfunctions on at least one last textile machine 1.3, 1.4, only controls the remaining flaps 10.
  • FIG. 3 A scenario is shown in which in the first group with the textile machines 1.1, 1.2, 1.3 the last textile machine 1.3 in the first transport direction A is disrupted. Accordingly, the flap 10.1c closest upstream of the last textile machine 1.3 is in its closed position. In the second group of textile machines 1.3, 1.4, 1.5, the last two textile machines 1.4, 1.5 in the second transport direction B are disrupted. Accordingly, the flap 10.2c closest upstream of the last two textile machines 1.4, 1.5 is in its closed position. In this way, clogging of the strand ends 14.1, 14.2 is prevented in both groups and the textile machines 1.1, 1.2 and 1.6 located upstream of the closed flaps 10.1c, 10.2c can continue to run undisturbed.
  • the closed flap 10.c; 10.1c, 10.2c can be reopened once the respective fault has been resolved.
  • the operator can put the faulty textile machine back into operation after the fault has been resolved.
  • the control unit 13 only opens the respective flap again after stable production has been achieved.
