Abstract

An endless conveyor for ring spinning frames has bobbin spindles (13) for uptake of full and/or empty bobbins. To ensure trouble-free transfer to or from the bobbin spindle (13), the bobbins when viewed in the direction of feed of the endless conveyor (17), must be precisely positioned so that in a predetermined doffing position they come into alignment with a spinning station (11) or other bobbin-carrying arrangement. Each bobbin spindle (13) is fastened to the endless conveyor (17) by means of a driver (19) so as to be adjustable in the direction of feed of the endless conveyor (17).

Description

The invention relates to a spinning machine, in particular a ring spinning machine, according to the preamble of patent claim 1.

In a known ring spinning machine of this type (GB-PS 1 168 638), the sleeve pins are attached directly to the endless conveyor designed as a horizontal conveyor belt. The endless conveyor is generally designed as a steel belt which warps as little as possible, so that the predetermined distances between the sleeve journals, which must exactly match the distances between the spinning positions, remain unchanged even when the machine is operated for a long time.

While in the ring spinning machine according to GB-PS 1 168 638, the sleeve journals are arranged half the distance from the spinning positions, in order to be able to accommodate an empty tube and a full tube (cop) of the assigned spinning position at the same time during doffing, it is also possible to use the as Belt-formed endless conveyor only to provide sleeve pins at a distance from the spinning stations, an additional pin then having to be provided at each spinning station in order to temporarily accommodate one of the sleeves to be replaced when changing the sleeves (US Pat. No. 3,905,184).

Furthermore, it is already known (EP-A-0 061 432) to provide an endless conveyor on each machine side of a ring spinning machine, both ends of each endless conveyor being equipped with sleeve pins, so that when a full sleeve (cops) is replaced by an empty sleeve, the full sleeve is initially used can be plugged onto an empty sleeve pin, while an empty sleeve is then removed from the sleeve pin of the other strand assigned to the same spinning station and is placed on the spindle of the spinning station. In this known ring spinning machine, the sleeve journals are directly connected to the endless conveyor via elbows.

It is also already known (JP-OS 57-161 134) that the peg trays used in the winding machine connected to the ring spinning machine can also be used as empty tube feed means or full tube discharge means, in that these peg trays, which generally consist of a circular disc and a central pin arranged vertically thereon, to be displaced in a guide rail running around the ring spinning machine, the diameter, in particular the length of a pin slide, being slightly smaller than the distance between two adjacent spinning positions. The individual pin slides are in contact with one another and are pushed forward by exerting force on one or more pin slides, the thrust force being at least partially transmitted by the direct contact of the pin slides. A conveyor device for such trunnion slides is also known from DE-OS 35 44 560.

A disadvantage of the ring spinning machine according to JP-OS 57-161 134 is that the sleeve journals are not exactly in alignment with the spinning positions when a group of journal carriages with empty sleeves on one machine side has been moved in front of the assigned spinning stations. Therefore, before the sleeve can be changed, in the known ring spinning machine, a rake has to be pushed between the journal slides at right angles to the longitudinal axis of the spinning machine, so that the distances between the adjacent sleeve journals are exactly coordinated with the distances between neighboring spinning positions.

In a similar sleeve transport device (DE-OS 37 12 027) is used with a reciprocating rail or the like which extends along the spinning positions and which cooperates with pin slides which can be displaced in a guide rail in such a way that these are gradually moved up to the assigned spinning position . So that the trunnion slides are exactly aligned with the assigned spinning station, they must either have a length exactly equal to the distance between the spinning stations, or there are latch-like pivotable locking elements on the reciprocating rail, which are located exactly at the distance from the spinning stations, so that the locking elements ensure an exact alignment of the trunnion slides with the assigned spinning station even when the holding sledges are not in contact with one another. However, the pawls have to be assembled at exactly the right place on the rail with a high manufacturing effort.

The object of the present invention is to provide a spinning machine of the type mentioned, in which, even after the assembly of the endless conveyor and in particular after the production of the longitudinal tension required for the operation of the endless conveyor, the trunnions have been defined in a simple manner and with little structural effort Place of the endless conveyor can be brought and then fixed so that when the endless conveyor is arranged in the sleeve changing position, each support pin is located exactly at the assigned spinning position or on the associated sleeve support arrangement at which a sleeve transfer or a sleeve change is to take place.

To achieve this object, the features of the characterizing part of claim 1 are provided.

The idea of the invention is therefore the driver not to be permanently attached to the endless conveyor, which is preferably designed as a vertically extending steel belt, but to provide a possibility that the drivers, even after the endless conveyor has been installed on the spinning machine, at least to a certain extent adjusted in the conveying direction relative to the endless conveyor and then adjusted in the found one Position can be set.

In this way, uncontrolled expansions of the endless conveyor during assembly and energization in the spinning machine can have no adverse effect on the exact positioning of the drivers relative to the spinning positions or the sleeve removal points, because this positioning is carried out precisely afterwards.

According to claim 2, the sleeve pins can be acted upon indirectly by the drivers via pin slides. But it is also possible to attach the sleeve pin directly to the driver according to claim 3.

The mounting rail according to claim 4 takes up the weight of the pin carriage or pin.

It is particularly advantageous if the drivers are continuously adjustable, because even the smallest inaccuracies in the arrangement of the drivers on the endless conveyor can be eliminated.

Three particularly advantageous practical embodiments of this embodiment are characterized by claims 6 to 8.

In many cases, however, it is also sufficient if only adjustment in small steps is possible. This embodiment has the advantage that the transfer the driver can be carried out from one projection to the next or from one opening to the next relatively easily and generally without the release of any clamping means. This embodiment is particularly easy to use.

A particularly preferred application of the invention is characterized by claim 10. In the case of a ring spinning machine, a particularly exact positioning relative to the spinning positions is important, so that the invention is used here with particular advantage.

However, it is also possible to apply the invention according to claim 11 to the empty tube return conveyor belt for flyer tubes, the embodiment according to claim 9 and / or the development according to claim 12 being particularly expedient.

A preferred assembly method for the endless conveyor according to the invention is characterized by claim 13.

According to FIGS. 1 and 2, an endless conveyor in the form of a vertically arranged steel belt 17 is provided in front of a machine side of a ring spinning machine 27 with spinning stations 11 arranged at the same distance. According to FIG is endlessly guided around with spinning stations 11 arranged on both sides.
On the endless conveyor 17, drivers 19 are arranged in alignment with the individual spinning stations 11 of the ring spinning machine 27, which, according to FIGS. 1 and 2, have a vertical plate part 19 ″ extending parallel to the conveyor belt 17 and a U-shape from above over the conveyor belt 17 bent hook part 19 ''', so that a downwardly open slot 115 is formed which has a complementary shape to the conveyor belt 17.

Compared to the hook part 19 ''', a clamping screw 77 is screwed into a threaded bore 116 of the plate part 19'', which with its end facing the conveyor belt 17 abuts the latter and thus clamps the hook part 19''' against the conveyor belt 17. After loosening the screw 77, the driver 19 can be in or against the conveying direction f relative to the conveyor belt 17 are moved, which happens until the exact alignment with the assigned spinning station 11 has taken place. The clamping screw 77 is then tightened and the driver 19 is thus fixed on the conveyor belt 17.

The clamping screw 77 and the hook part 19 '' 'are located in the upper edge region of the conveyor belt 17, where the plate part 19' 'and the hook part 19' '' according to FIG. 1 have the smallest possible width B, so that the conveyor belt 17 can be guided around without problems around the deflecting rollers 39, 40, 41, 42 is ensured, which according to the broken line in FIG. 2 extend axially only to the lower end of the hook part 19 '' ', so that the flat contact of the conveyor belt 17 on the circumference of the deflecting rollers 39, 40, 41, 42 is not hindered by the driver 19.

From the lower end of each driver 19 extends perpendicular to the conveyor belt 17 and away from this a driver finger 19 ', which engages behind the foot 13' of a vertically standing sleeve pin 13, which projects vertically upwards from a horizontal circular cylindrical sliding body 44 which is parallel on a horizontally to the endless conveyor 17 extending support rail 22 is slidably disposed. The sliding body 44 and the sleeve pin 13 together form a pin slide 18.

2, the mounting rail 22, which is arranged in a machine-fixed manner, can also have a lateral guide 56 on its outside, which can also be provided with an upper bend 80 from above for the purpose of holding the sliding bodies 44.

If necessary, a side guide 117 could also be provided on the inside of the mounting rail 22, so that the pin slides 18 are slidably guided on all sides parallel to the endless conveyor 17.

Empty sleeves 31 (FIG. 2) or full sleeves spooled with yarn can optionally be placed on the sleeve pins 13 and are to be transported from or to a winder, not shown.

The operation of the spinning machine with endless conveyor described is as follows:
First, the conveyor belt 17, which is provisionally equipped with the carriers 19, is placed around the deflection rollers 39, 40, 41, 42 of the ring spinning machine 27 in the manner shown in FIG. 11. Then, for example, the desired tension of the steel conveyor belt 17 can be produced by a controlled displacement of the deflection rollers 41, 42 in the direction of the arrows S, on the basis of which the conveyor belt 17 stretches somewhat. Now the conveyor belt 17 is brought into the sleeve change position, in which a particular support pin 13 is to be arranged exactly in alignment with the associated spinning station 11. After the conveyor belt 17 has been brought into the sleeve change position, the associated catches 19 are adjusted in or against the conveying direction f after loosening the clamping screw 77 by applying a pin slide 18 to each catch finger 19 'until the assigned catch pin 13 is more exact Alignment with the associated spinning station 11 is located. This exact alignment is carried out successively at all spinning positions. After a certain sleeve pin 13 has been precisely aligned with the assigned spinning station 11, the clamping screw 77 is tightened again, so that the exact positioning of the driver 19 in question is ensured in the long run.

Should there be any warping of the conveyor belt 17 after a long period of operation, the exact alignment can each driver 19 to the associated spinning station 11 can be restored at any time by loosening the clamping screw 77 and corresponding relative displacement to the conveyor belt 17.

FIG. 11 also schematically shows a vertical endless conveyor belt 17 'which is arranged in the center of the ring spinning machine and extends in the machine longitudinal direction for the return transport of empty flyer sleeves 31' (FIG. 18) fed via sleeve support arrangements 120. The endless conveyor belt 17 ′ is guided at the ends of the ring spinning machine 27 via deflecting rollers 118, 119 with a vertical axis and is formed by a steel belt with a vertically arranged flat surface. Carriers 19 are attached to the belt in this case with horizontal sleeve journals 13 'extending from the endless conveyor belt 17' at defined intervals which, however, vary according to the invention. For the sake of clarity, only three such drivers 19 with trunnions 13 'are indicated in FIG. 11.

Fig. 3 shows a perspective section of the return conveyor belt 17 'with an attached driver 19 which carries a projecting sleeve pin 13' with a roof-shaped cross section. 3 and 4, the driver 19 in the upper region at the rear has one or preferably two adjacent hook-like projections 114 which engage in rectangular openings 112 in the return conveyor belt 17 ', so that the driver 19 is attached to the return conveyor belt 17'. Analogously to FIG. 2, the deflecting rollers should be arranged axially below the counter projections 114 so as not to collide with them. The openings 112 should therefore be provided as far up as possible in the return conveyor belt 17 '. It is also possible to provide circumferential grooves in the deflection rollers for receiving the part of the counter-protrusions 114 projecting from the rear.

The openings 112 are arranged next to each other on a straight line parallel to the longitudinal extent of the return conveyor belt 17 ', so that the catch 19 can be attached to the return conveyor belt 17' at different points by hooking into adjacent openings 112 in or against the conveying direction f . In this way, the drivers 19 and the sleeve pins 13 'can be brought into exact alignment with sleeve support arrangements 120, from which the empty flyer sleeves 31' (FIG. 18) can be removed, which is described in detail below with reference to FIGS. 15 to 18 .

5 and 6, hook-like projections 111, which cooperate with corresponding recesses 113 on the rear of the catches 19, can also be provided at the front of the return conveyor belt 17 '. A driver 19 is preferably suspended on two spaced hook-like projections 111.

The width of the openings 112 and / or the projections 111 is 0.5 to 1.5 mm, in particular 1 mm. The distance or the division of the periodically repeating openings 112 or projections 111 is 2 to 3 mm, in particular 2.5 mm.

12, 13 and 14 show a somewhat different embodiment of the drivers 19 and the sleeve pins 13 'projecting horizontally therefrom. The driver 19 is designed as a plastic part with a flat, U-shaped cross section, the two legs 19 ″ of the plastic part being snapped over the upper or lower edge of the conveyor belt 17 ′.

At the level of the openings 112 located essentially in the middle there are iron tabs 19 '' 'on the back of the drivers 19, which engage in a form-fitting manner in each of the openings 112 and cooperate with a magnetic indicator 28 arranged behind the machine, which emits a signal if it is aligned with an iron tab 19 '' '.

Extending horizontally from the lower front area of the driver 19 toward the front is the sleeve pin 13 ', which has a roof-like cross section, the load-bearing capacity and stability of which is increased by supporting ribs 32 running between it and the driver 19.

According to FIG. 14, two iron tabs 19 '' 'are arranged next to each other on the back of the flat and flat web of the driver 19 at a distance of, for example, 1 mm, so that they engage in two adjacent openings 112 in the endless conveyor belt 17'.

15, 16, 17 and 18 illustrate how full flyer sleeves 33 (FIG. 16) are conveyed to the spinning positions and empty sleeves 31 '(FIG. 18) to the sleeve journals 13' of the drivers 19 according to FIG. 3 to 6 or 12 to 14.

15 and 16 pass through a coupling pin 34 (Casablanca pin) and a carrying and guide adapter 30 on a trolley 35 suspended, with the roving full sleeves 33 to the spinning stations 11 of the ring spinning machine 27 by the multiple Transport carriages 35 carrying full sleeves 33 move along feed rails 36 running along the ring spinning machine 27 and in each case one or two full bobbins are passed over switches 37 to cross rails 120 which belong to a sleeve transport gate 29. There are the full sleeves 33 with the individual spinning positions connected by the fuse is fed to the drafting systems, not shown.

The carrying and guide adapter 30 can be suspended on the one hand by means of bends 30 ′ in guide recesses 35 ′ on the underside of the transport carriage 35, but due to its hollow profile 30 ″ it can also be pushed onto a corresponding guide area 120 ′ of the cross rail 120 (FIG. 16, 17).

15, the sleeve journals 13 'of the carriers 19 fastened to the conveyor belt 17' can be aligned with the cross rails 120 in the sleeve change position by hanging the drivers 19 in the correct place on the conveyor belt 17 ', the fine division of the openings 112 (Fig. 3 and 12, 14) is used.

If the transverse rails 120 and the sleeve journals 13 '(FIG. 15) are aligned exactly, the empty spools 31' according to FIG. 18 can be pushed onto the associated sleeve journals 13 'by the transverse rail 120. Between the sleeve pin 13 'and the given opposite end of the cross rail 120 there is a gap 120' '(FIG. 15) which is so narrow that the carrying and guide adapters 30 can be easily pushed onto the sleeve pin 13' from the cross rail 120, whereupon the position of Fig. 18 is obtained. If the endless conveyor belt 17 'is now set in motion in the direction of the arrow in FIG. 17, the empty sleeves 31' hanging on the carrying and guide adapters 30 are conveyed away from the spinning stations 11 and back to the flyer.

The above-mentioned pitch of approximately 2.5 mm for the openings 112 is sufficient, since this means that the maximum tolerance is ± 1.25 mm, which is in view of the existing guide play is sufficient. The same dimensions and tolerances also apply to the Kops band 17.

The drivers 19 according to FIGS. 12 to 14 are made of plastic because they can be made easily and cheaply as a result. However, the tabs 19 '' 'must be made of metal because the endless conveyor belt 17' is a steel belt and otherwise excessive wear would occur. The two iron tabs 19 '' 'according to FIGS. 12 to 14 are spaced 2.5 mm apart by this distance. However, it would also be possible to leave a free opening 112 between the two iron tabs 19 '' ', as a result of which the distance between the iron tabs in the conveying direction would then be 5 mm. The magnetic indicator 28 is used to stop the endless conveyor belt 17 '. It has been shown that the reliability is significantly increased if there are two iron tabs 19 '' 'on a driver 19.

Two further advantageous embodiments for the length-adjustable attachment of the driver 19 to the endless conveyor 17 are described below with reference to FIGS. 7 to 9. This embodiment is particularly suitable for cop removal and for feeding the corresponding empty tubes to the spinning stations 11.

In the exemplary embodiment according to FIG. 7, the vertical steel conveyor belt 17 has a spring 73 which projects inwards to the deflecting roller 39 and which engages in a circumferential groove 74 of the deflecting roller 39. The remaining deflection rollers 40, 41, 42 have corresponding circumferential grooves 74. This measure ensures that the vertical alignment between the steel belt 17 and the deflection rollers is correct.

In the lower area, the vertically standing conveyor belt 17 has an outwardly pointing spring 75 which - in the conveying direction slidably - engages in a corresponding groove 76 of the driver 19. By means of schematically indicated clamping means 77, the driver 19 can be fixed in different longitudinal positions relative to the conveyor belt 17. In this way, a longitudinal adjustment of the driver 19 relative to the endless conveyor 17 is possible.

In its lower area, the driver 19 has a T-shaped guide recess 78, by means of which it slidably rests on a profile 79 with a T cross section that is complementary thereto. The T-profile is firmly connected to the mounting rail 22 and the lateral guide 56, i.e. machine-proof. Due to this guidance of the drivers 19, these and the conveyor belt 17 are also supported and guided correctly in the vertical direction between the deflecting rollers 39, 40, 41, 42.

The circular-cylindrical sliding body 44 of the pin carriage 18 is slidably mounted on the mounting rail 22 and is advanced by the driver finger 45 of the driver 19 when the endless conveyor 17 is put into circulation.

The lateral guides 56 are bent at their upper end to a guide edge 80, so that the sliding bodies 44 are secured against lifting from above and can only be moved in the desired conveying direction.

8 and 9, the endless conveyor 17 is formed by a circumferential steel cable, on which the drivers 19 provided with corresponding receiving grooves 81 are clamped in a desired longitudinal position by clamping means 77. In this way, too, the drivers 19 can be attached to the endless conveyor 17 in a variable length. In this embodiment, 19 permanent magnets 49 are provided on the drivers, which with a magnetic insert 58 Interact circumference of the sliding body to releasably hold the pin carriage 18 on the driver 19.

Driver pins 82, which are fixed to the driver, extend downward from the underside of the driver 19 into a longitudinal groove 83 of the mounting rail 22, which, in cooperation with the lateral guide 56 on the opposite side, ensures a perfect longitudinal guidance of the pin carriage 18.

According to FIG. 10, the mounting rail 22 is arranged with the lateral guide 56 sloping slightly outwards. However, the sleeve pin 13 still protrudes substantially upwards. From the support rail 22, a profile 121 extends in the manner shown around the conveyor belt 17 at a distance, with receiving beads 122, 123 running below and above parallel to the conveyor belt 17, onto which from the outside holding shells 124, 125 of a driver 19 in the conveying direction are slid on.

From the carrier 19 extends to the conveyor belt 17, a hook-shaped counter-projection 114 ', which extends through an opening 112 of the conveyor belt 17 formed by analogous to FIGS Conveyor belt 17 comes to the plant.

Due to the support of the driver 19 via the upper shell 125 on the upper bead 123, the driver 19 in this case carries the conveyor belt 17 via the hook-like counter-projection 114 ', so that this merely performs a driving function and except on the deflection rollers 39, 40, 41, 42 need not be performed particularly. The driver finger 19 'is again arranged on the driver 19 for driving the journal carriage 18.
