Definitions
- the invention relates to a short chain warping machine with a lockable drum, on the at least one thread guide in one end face Feed plane revolves and on its circumference axially parallel Partial bars and conveyor belts that are placed on them Transport threads parallel to the axis, provided are, the partial rods on their of the said end face adjacent end have a selection element, that of an axial motor arranged inside the rod is adjustable in two positions to the threads to be placed either on or under the partial bar.
- the partial bars serve to form crosshairs or to separate threads can also be used for other purposes, e.g. For education a size division can be used.
- a hook is provided in one of the feed level penetrating axial slot back and forth can. It is driven by a pneumatic piston-cylinder unit, the inside of the hollow trained Partial bar is arranged and over one of the length of the partial rod corresponding air line from an outside of the rod arranged control valve actuated becomes.
- the hook is on one side of the Feed level, it pushes on the thread when actuated the sub-staff.
- the hook is on the other Side of the feed plane, he pushes the thread over that End of the partial rod, so that the thread over a The sloping part of the rod reaches under the partial rod.
- the invention has for its object a short chain warping machine of the type described in the introduction, in which the necessary for the assignment of the partial bars Thread selection even with shorter cycle times between two successive thread guide passes, works reliably.
- this object is achieved in that the selection element is formed by a selection lever which extends approximately radially to the drum and is pivotable about an axis at the end of the partial bar and its free end in the first position one side of the feed level and the second Position on the other side.
- the thread slides along one side of the separation lever, possibly over a known inclined surface, down to the sub-bar.
- the separation lever is located on the other hand, in the second position, slips the separated thread along the other side of the separation lever except for the partial bar.
- the separation element does not need to move threads and can therefore work faster under the same circumstances. Even a small swivel angle between the two Positions is sufficient to the free end of the selection lever to hike a relatively long way allow. Small swivel angles in turn allow high ones Working speeds. Still is a safe one Cutting the threads during the downtime of the selection lever guaranteed. One can therefore with higher machine speeds or simultaneously with one Variety of thread guides work.
- the pivot axis of the selection lever lies in the feed level.
- the two positions The selection lever can therefore be symmetrical to the feed level to be ordered. This gives the best results regarding the slipping of the selected threads on the selection lever and the most favorable ratio from a small swivel angle to a large path of free Ends of the selection lever between the two positions.
- the selection lever through an arm of a two-armed lever is formed, the second arm directed into the bar interior and over one Coupling element connected to the actuator of the axial motor is.
- the use of the two-armed lever and the Coupling link represents a particularly simple variant to the selection lever with the inside of the partial stack connected drive.
- pivot axis of the two-armed Lever opposite the axis of the actuator in Moved towards the free end of the selection lever is.
- the axis offset ensures that by lateral buckling of the coupling link and second arm the desired actuation of the selection lever takes place.
- the stop is a Damping pad carries. With very fast movement of the Selection lever, the damping pad lowers the noise level.
- the Axial motor is a pneumatic piston-cylinder unit which is supplied with compressed air via a control valve that is housed near the unit in the sub-staff is. Since the selection lever only selects the threads, but does not have to move on the partial rod and because relatively small swivel angles are sufficient for selection, can the pneumatic piston-cylinder unit run much smaller than before, such that the control valve is no longer outside the sub-rod, but can be accommodated in the sub-staff. As a result, A compressed air hose several meters long is not required between control valve and unit with the result that the piston is practically immediately after valve actuation responds and quickly adjusts the selection lever.
- a particularly recommendable solution is that there are several thread guides and the cycle time is less than 60 ms. Even with these short cycle times safe operation is still guaranteed.
- Short chain warping machines of the type considered here those shown schematically in Figs. 1 and 2 Construction.
- An initially fixed drum 1 instructs their circumference conveyor belts 2 and - in secant sections - Partial bars 3.
- the conveyor belts are placed around pulleys 4 and 5. They are driven so that her outer run 6 is slowly heading towards arrow 7 moves.
- Two thread guides 8 and 9, attached to a common rotating support 10 put threads on the conveyor belts 2, so that over time the entire drum 1 with successively fed threads is wrapped.
- the partial rods 3 serve to form a crosshair, for separating or cutting the threads or for the department certain thread groups, as is known per se, for example from DE 197 17 443.
- Such a crosshair 11 is indicated in Fig. 2. It assumes that the threads normally deposited on the partial bars partially have to be placed under the partial rods 3. The present invention addresses this problem.
- the partial rod 3 is through a tube 12 is formed which has a slope at its end 13 has.
- a two-armed lever 14 has a selection lever 15 and a second arm 16 and is mounted rotatably about a pivot axis 17.
- the selection lever 15 can take two positions, namely the Position A shown in Fig. 3, in which the free End of the selection lever 15 on one side of the by the thread guides 8 and 9 determined feed plane 18th is located, and the position B shown in Fig. 4, in the the free end of the selection lever 15 on the other Side of the feed level 18 is located.
- the fed threads slide on the side surface 19 of the selection lever 15 down and get over the slope 13 under the sub-bar 3.
- the Threads either go directly to the Partial rod 3 or 20 through the other side surface of the selection lever 15 led there.
- An insert 21 carries a pneumatic piston-cylinder unit 22, the piston rod 23 with one in use 21 guided actuator 24 is connected, and the bearing for the pivot axis 17.
- the actuator 24 is a Joint 25 connected to a coupling element 26, the in turn via a joint 27 with the second arm 16 the double-armed lever 14 is connected.
- the piston rod 23 extends to the right the position A of FIG. 3, in which the second arm 16th is next to the slope 13.
- the piston rod is in moves in the opposite direction, the Position B of FIG. 4, in which the second lever arm 16 a stop provided with a damping buffer 28 29 is present.
- the location is such that the dead center position has not yet been reached, so because of the transfer the pivot axis 17 relative to the piston axis the next actuation of the piston-cylinder unit 22 the coupling member 26 pivots down again.
- Control valve 30 which via a line 31 with compressed air is supplied and this over two lines 32 optionally leads to one or the other side of the piston.
- the control valve 30 is operated by an electrical actuator 33 driven, the electrical Control lines 34 in turn in the cavity of the partial rod 3 run.
- the swivel angle was Selection lever 15 about 20 ° and the way to be covers the free end between positions A and B, was about 30 mm.
- the cylinder of the unit 22 had a diameter of 10 mm instead of 20 mm and the Stroke was only 10 mm instead of 25 mm previously.
- a control valve 30 in small format, whose dimensions allow it to be inside the Part 3 to be housed. As a result, no longer apply all delays so far due to long air supply hoses between the control valve and piston-cylinder unit were necessary.
- Fig. 5 shows over time the control commands S that the Actuating device 33 of the control valve 30 is supplied become.
- a full signal means that the position A ingested.
- missing signal means that position B should be taken.
- the control command is conveniently from a self-programmable Control (PLC) delivered and from the approaching Thread sensor 8 or 9 triggered.
- PLC self-programmable Control
- the duration of the individual commands therefore correspond to the cycle time z, that is, the time interval between successive ones Thread guide passages.
- Fig. 6 shows the speed v of the piston movement the piston-cylinder unit 22 over time. Since the Actuation of the piston practically without any delay starts with the actuation of the control valve 30 and the stroke to be traversed is relatively small reaches the desired position A or B very quickly.
