Description

DESCRIPTION

Feeding method and feeder for feed bobbins

The invention relates to a feeding method and a

Feeding device for one or more feed bobbins on twisting machines with the features in the preamble of the method and device main claim.

Twisting machines of various types are known in practice, which twine one or more threads or wires. The twisting machines are manually equipped with feed bobbins. So that the operator can reach the feed bobbins, which are often arranged in a poorly accessible place in the upper twisting area, the twisting machine has an attached pivoting device with which the feed bobbins are moved back and forth between a lower, ergonomically favorable loading position and the high lying working position can. The manual assembly is cumbersome and time consuming. In addition, the coil weight is limited for ergonomic reasons.

It is an object of the present invention to provide a better placement option for twisting machines.

The invention solves this problem with the features in

Process and device main claim.

The claimed feeding technique relieves the operator and simplifies the feeding of feed bobbins to one or more twisting machines. In addition, the loading process is accelerated. This increases the availability of twisting machines and improves the utilization and the efficiency of the twisting machines and the complete twisting machine. In addition, staff costs are reduced.

BESTATIGUNGSKOPE The feeder can have a multiple function and transport the coils inside the plant, feed the twisting machine, position it there in a trigger position and provide it to the thread take-off and then, if necessary. remove existing empty carrier sleeves again.

At least part of the feed bobbins used on a twisting machine are fed by the feeding device with one or more bobbins. The bobbins can be equipped at a remote charging station with one or more feed bobbins and then moved to the twisting machine and there provided to take the thread. A manual Spulenbestückung on the twisting machine is unnecessary or can be reduced to a smaller extent. Suitable loading aids for optimal ergonomics can be provided at the central charging station. This also allows an increase in the coil weights.

The supply bobbins moved on the bobbins can be positioned and provided on the twisting machine in a take-off position and with suitable alignment to a preferably stationary thread guide. The bobbin supply via the movable bobbin can be done individually on each twisting machine. Alternatively, a plurality of bobbin carriers can be coupled together to form a bobbin-carrier train which permits simultaneous bobbin feeding at several twisting machines, in particular if they are arranged one behind the other in a machine row. An articulated coupling of the coil carrier makes the coil carrier train curvy. Due to the single or collective supply of feed bobbins to one or more twisting machines, the operator in one embodiment only needs to produce the thread connection by splicing or knotting in order to enable a continuous yarn feed to the twisting machine. In a collective assembly of a machine series all feed bobbins can be changed in one go by the one coil carrier train is run with the processed feed bobbins or the empty tubes and replaced by another spool carrier train with full feed bobbins. On a twisting machine or a machine series several movable bobbins can be positioned with supply bobbins parallel and individually exchangeable. This parallel arrangement allows the replacement of the empty bobbin or the empty bobbin row, while the other

Feed bobbin or bobbin row is still in unwinding. As a result, a standstill of the twisting machine or machine series can be avoided when changing bobbins.

If there is only one operator to connect the thread ends, it takes a while for all nine feed bobbins to be thread-tied. It is advantageous if one or more other stationarily arranged feed bobbins are present on the twisting machines, which are manually plugged and changed by the operator. By a series connection of the bobbin threads of the thread sequence and the twisting machine function is maintained, even if the present on the movable bobbin supply bobbin is completely emptied. By stationary feed bobbins also runtime differences between the twisting machines can be compensated. Furthermore, a larger time window is available for the entire placement and changing process of the original bobbins.

The individual moving bobbins or the

Spool carrier can be moved manually. Alternatively, at least one mechanical conveyor drive can be available. These can be stationary conveyor drives. Alternatively, the coil carrier or coil carrier trains may have their own entrained drive. In the subclaims further advantageous embodiments of the invention are given.

The invention is illustrated by way of example and schematically in the drawings. In detail show:

FIG. 3 shows a plant representation for FIG. 2 with a plurality of twisting machines and feed devices arranged side by side;

FIG. 4 shows an enlarged detail view of stationary and movable coil carriers according to FIG. 1 and FIG

Figure 5: a schematic view of a twisting machine with several machine rows and Spulenträgerzügen and further processing machines.

Figures 1 to 3 show a twisting machine (2) in a schematic cross section. The machine can twine one or more threads from feed bobbins (8, 9, 10, 11, 12) and wind them up on a twisting bobbin (3). The threads can be of any type and consist of plastic fibers or other materials, for example. The term "twisting machine" is also understood to mean so-called cabling machines and other machines for twisting any number of threads. The twisting machine (2) may be of any type. In the twisting machine (2) shown, a thread (not shown) is twisted by a machine-internal supply spool (8) and at least one drain thread (14) supplied by one or more external supply spools (9, 10, 11, 12). The twisting machine (2) shown operates on both sides and produces on the left and right side in each case a twisting coil (3) from feed bobbins (8,9,10,11,12).

The twisting machine (2) has a discharge device (33) which includes a central conveyor for the finished twisting coils (3). In Figure 1, such a twisting spool is shown in dashed lines on the conveyor. The twisting reels (3) are connected to supporting devices, e.g. a lever mechanism, held with which they can be moved between the left or right swung-out winding position and the central, inner delivery position on the conveyor. The twisting devices present in the twisting device for twisting the threads are not shown.

The twisting machine (2) can be present individually or multiple times. In particular, several of the twisting machines (2) shown can be arranged one after the other in a machine row (4) immediately thereafter and have a continuous common discharge device (33). Figure 5 shows such a series arrangement. One or more such rows of machines (4) can be combined in a larger twisting unit (1), wherein between the rows of machines (4) lanes (5) for an operator (32) are left free, from here the twisting machines (2) resp Machine series (4) can operate on both sides. FIG. 3 shows this arrangement.

At least part of the external supply bobbins (9, 10) is fed by means of a feed device (6) to the individual twisting machines (2). In addition, can be stationary present in the field of twisting machine (2) supply bobbins (11,12) are present, which are manually changed by the operator (32). Figure 1 shows a variant with stationary feed bobbins (11,12) and a movable feed bobbin (9), the double and both sides of the

Twisting machine (2) are present. In the variant of FIG. 2, two pairs of movable feed bobbins (9, 10) are fed separately from one another.

The feeder (6) has one or more transport guides (23) with one or more movably mounted thereto and with at least one feed bobbin (9,10) loadable bobbins (20,21). For loading the bobbin carriers (20, 21) there is at least one charging station (7) which can be arranged locally separate from the twisting machine (2). Figure 5 shows this arrangement in the said twisting machine (1). The transport guide (23) is here e.g. designed as a circular path that connects all rows of machines (4) and the one or more times existing charging station (7) together, along the rows of machines (4) guide tracks are laid parallel, which are connected by turnouts end to the circular path. On each operating side or component side of the twisting machines (2) is such a guide strand.

The twisting machines (2) can be approached and operated individually with the coil carriers (20, 21). In an arrangement in rows of machines (4), it is recommended that the coil carrier (20,21) to each other

Bobbin train (22) to couple, with all in a machine series (4) twisting machines (2) together and possibly simultaneously operated and can be supplied with supply bobbins (9,10). When the coil carriers (20, 21) are connected to one another in an articulated manner, the coil carrier pull (22) is curved and can also pass through narrower radii. The coil carriers (20,21) have a distance between them, which is adapted to the dimensions and possibly distances of the lined up twisting machines (2).

The transport guide (23) can be in any suitable

Be arranged relative to the one or more twisting machines (2). In the embodiments shown, the twisting coils (3) are arranged in the upper region of the twisting machines (2). Here, the arrangement of the transport guide (23) is recommended above the twisting machines (2), wherein the coil carrier (20,21) are mounted suspended and the drainage thread (14) is supplied from above. This has the advantage that the lanes (5) remain free and can be passed by the operators (32) without hindrance. Alternatively, the transport guide (23) can also be positioned lower, wherein in addition a vertical arrangement and storage of the coil carrier (20,21) is possible. Such an arrangement is particularly recommended when the twisting coils (3) are arranged lower in a twisting machine (2).

The transport guide (23) may be constructively designed in any way. In the embodiment shown, it comprises one or more stationary rails (24), e.g. attached to a raised frame (31) or to the ceiling. In the area of the twisting machines (2), the running rails (23) are aligned longitudinally and parallel to the machine row (4). The rails (23) can be arranged directly above the twisting machines (2) or slightly laterally offset in the lane area.

On the rails (24), the coil carrier (20,21) with drives (25) are movably mounted. As Figure 4 illustrates in detail, the drives (25) may have a plurality of freely rotatable rollers arranged at an angle to each other, which guided in the rails (24) - S -

are that only a movement in the rail longitudinal direction is possible. Offset or pivotal movements across and / or along the rail extension are preferably prevented.

Alternatively, other types of drives are possible. Further, the transport guide (23) may be formed of stationary rollers or other movable or rigid guide means and the drives (25) may be formed by correspondingly adapted parts.

The movable coil carriers (20,21) can be moved by hand. Preferably, the feed device (6) has at least one conveyor drive (26) for the individual coil carriers (20, 21) or for one or more

Coil carrier cables (22). In the illustrated embodiment, the conveyor drive (26) is stationary and has one or more of the coil carriers (20,21) engaging the driving elements (27). This can e.g. 4, the stationary bearing friction wheels are shown, which are connected to a motor drive, not shown, and act on both sides of a drive body (28) on the bobbins (20,21). The propellant body (28) is e.g. designed as a driving sword or as a bar, which is located below the drive (25). Of the

Drive body (28) can be seen in the rail longitudinal direction over the length of the associated bobbin (20,21) and extend at its two ends coupling elements for preferably articulated connection with the drive body (28) of the adjacent bobbin

(20,21). The coupled drive body (28) form an articulated Trebleiste within which on the couplings tensile and compressive forces can be transmitted. By means of this arrangement, a few drive elements (27) are sufficient to move a package carrier pull (22). Of the

Conveyor drive (26) is controlled and has end stops or other positioning means, the positioning of the allow individual movable bobbin (20,21) or a Spulenträgerzugs (22) in the desired withdrawal position (13) relative to the or to be operated twisting machines (2). In a modified embodiment (not shown), the individual coil carriers (20, 21) or the coil carrier trains (22) can have their own drive and a corresponding energy supply.

As FIGS. 1 to 4 illustrate, the movable coil carriers (20, 21) are designed as multiply angled, substantially L-shaped racks and carry at least one feed bobbin (9, 10). If one or more stationary supply spools (11, 12) are arranged on a twisting machine (2), these may likewise be located on an angled and, for example hanging on the frame (31) attached bobbin (29) are located. Alternatively, one or more stationary feed bobbins (11, 12) can also be arranged and stored directly on the twisting machine (2).

For the design and arrangement of the coil carrier

(20,21,29) there are different

Design options. In the variant of Figure 1, e.g. on each operating side of the twisting machine (2) a noncnαcitigcr stationary coil carrier (29) and a movable coil carrier (20) with associated

Transport guide (23) or running rail (24) arranged.

The stationary coil carriers (29) are e.g. on the outside 'and the movable coil carrier (20) arranged inside. The assignment can also be different and in particular reversed.

In the variant of FIGS. 2 and 3, there are no stationary feed bobbins (11, 12). Instead, two movable coil carriers (20, 21), each with its own travel rail (24), are arranged in parallel on each operating side and can be independently moved in this two-sided parallel arrangement and positioned opposite the twisting machine (2). The angled coil carrier (20,21) of each pair are in this case, for example, mirror images of each other aligned and each loaded with a feed bobbin (9,10).

The above-described arrangement also applies to a spool carrier pull (22) and the coil carriers (20, 21) coupled to one another. Further, it is possible in a modification that a coil carrier (20,21) has an increased length and extending over several twisting machines (2) and operated at the same time. Accordingly, several feed bobbins (9,10) are arranged one behind the other on such a longer coil carrier. In the shown and preferred embodiment, the length of the coil carrier (20,21) of length dea? a twisting machine (2), so that each bobbin carrier (20,21) operates a twisting machine (2).

The movable coil carriers (20, 21) can be positioned in a defined withdrawal position (13) on the individual twisting machine (2) or the machine row (4) and parked with suitable locking means. In this draw-off position (13), the thread take-off from the feed bobbins (9, 10) can take place on the movable bobbins (20, 21). In the withdrawal position (13), the movable bobbin carriers (20, 21) are also positioned opposite a yarn guide (18), which can be assigned to the respective twisting machine (2) to be operated. The

Thread guide (18) is arranged, for example stationary and located between the movable feed bobbins (9,10) and the movable and stationary feed bobbins (9,11,12). The thread guides (18) are attached, for example, on both sides of the twisting machine (2) hanging on the upright frame (31). Alternatively, they can also be attached to the twisting machine (2). In a further modification, the Thread guide (18) movable and, for example, be arranged on the bobbin (20,21) and be carried. The thread guides (18) may have, for example, an eye, possibly with a cantilever, for the passage and deflection of the thread (14, 15) and possibly a thread brake.

The stationary and movable feed bobbins (9,10,11,12) are mutually aligned obliquely with their coil axes (19) that meet the coil axes (19) in the withdrawal position (13) on the common thread guide (18). Preferably, the coil axes (19) intersect at a common point on the eye of the thread guide (18), which is arranged above the feed bobbins (9,10,11,12). Here, however, not too great accuracy is required, so that the intersection can also be slightly shifted or a skewed axis arrangement is possible. From the thread guide (18) of the drain thread (14) extends in a defined manner down to the twisting machine (2) and its twisting device.

In order to ensure an uninterrupted thread run, at least two feed bobbins (9, 10, 11, 12) can be positioned in the withdrawal position (13) according to the exemplary embodiments shown. The feed bobbins (9,10,11,12) with their thread ends by the operator (32) with each other by eg knots or splices or the like. connected. From a supply spool (9,10,11,12) leads the front upper end of the thread as a bobbin thread (15) to the thread guide (18), is deflected here and forms the drainage thread (14). The rear lower thread end of this supply spool (9,10,11,12) is connected to the front end of the thread at the top of the adjacent supply spool (9,10,11,12), so that thread connections (16,17) arise. In the coil arrangement of Figure 1, the two stationary feed bobbins (11,12) are coupled to each other by a thread connection (17), wherein the thread connection (16) the attachment to the movable Feed bobbin (9) creates.

The feed bobbins (9, 10, 11, 12) are attached with their inner sleeves or carrier sleeves (40) to bobbin mandrels (30) and are preferably held in a rotationally fixed manner. The threads are preferably iridescent in the axial direction on the feed bobbins and their carrier sleeves (40). The thread (14) is pulled by the twisting device or a conveyor, so that the bobbin thread (15) by itself when deducted from the supply spool

(9,10,11,12) umlaufend handles. The coil winding is schematically indicated in FIG. 4 on the stationary supply spool (12).

When the bobbin thread (15) is completely unwound from the first supply bobbin, it jumps through the thread connection (16,17) on the next feed bobbin, which is now unwound. In the variant of FIG. 1, after emptying the second supply spool (12), the bobbin thread (15) jumps over the thread connection (17) to the second stationary supply spool (11). By the aforementioned oblique orientation of the coil axes (19) to the thread guide (18) ensures that the bobbin thread (15) of the various feed bobbins (9,10,11,12) runs in the same manner and under the same deduction constraints.

The emptied feed bobbins (9, 10, 11, 12) are ready to be picked up and exchanged for full feed bobbins (9, 10, 11, 12) after skipping the bobbin thread (15) with their inner sleeves (40). The multiple arrangement of feed bobbins (9,10,11,12) ensures that there is enough time for the bobbin change, whereby it does not matter if the feed bobbins (9,10,11,12) within a coil row or a Spulenträgerzugs ( 22) run time-delayed one after the other. The movable feed bobbins (9,10) are changed by driving away the emptied bobbin (20,21) or an emptied Spulenträgerzugs (22) and by retracting new bobbin or a new Spulenträgerzugs. The stationary feed bobbins (11, 12) are changed manually by the operator (32). In the course of the exchange, the thread connections (16, 17) to the new supply bobbins are again created by the operator.

The weight of the stationary feed bobbins (11,12) is limited for ergonomic reasons, especially in a hanging coil assembly in the upper twisting machine area. The coil weights are usually e.g. 8 kg. The feed bobbins (9, 10) moved via the feed device (6) can have a much higher bobbin weight of 15 kg and more. Because of the runtime overlaps, integer multiples of the weight of the stationary feed bobbins (11, 12) are recommended, e.g. 16 kg, 24 kg, 32 kg etc .. The coil carrier (20,21) are designed accordingly in their carrying capacity.

The twisting machine (1) shown in FIG. 5 has a bearing (34) for feed bobbins (9, 10, 11, 12), which may be stored sorted by type and individually placed on support pins in containers (36). By means of suitable

Transport devices (35), e.g. Forklift trucks, the container (36) can be transported to the loading station (7) and provided for a local assembly of the coil carrier (20,21) and coil carrier trains (22). This assembly can be done manually or by machine.

The twisting bobbins (3) finished in a machine series (4) are transported via the discharge device (33) to the downstream end of the row and are made available here for collection. They can be attached individually or in succession to freely rotatable support pins of gate drain containers (39). This can done manually by operator or fully automatically with a corresponding Doffereinrichtung. The gate draining containers (39) may be located on transfer carriages which are movable on a rail track or the like transversely opposite the discharge ends of the machine rows (4). From the transfer trolley, the full Gatterablaufcontainer (39) via another transport device (35), eg forklift or the like., Picked up and brought to a gate drain (37). Possibly. is an intermediate storage possible. In the gate sequence (37), the twisting threads are removed from the twisting reels (3) and fed to a further processing machine (38), eg a weaving machine.

Modifications of the embodiments shown are possible in various ways. The features of the various embodiments shown can also be arbitrarily combined and replaced with each other.
