Description

DESCRIPTION

Method of storing coils and storage device

The invention relates to a method for storing spools and a storage device for spools, in particular for filament spools, with the features in the preamble of the main claim.

Such a storage device is known from practice. It is designed for highly sensitive filament spools that are manufactured in a spinning mill. The filament bobbins consist of a hollow core, to which a filament winding of yarn or fibers is applied. The known bearing device has a large number of coil carriers, which consist of long horizontally arranged rods, onto which a plurality of coils with the coil cores are pushed one behind the other. The coil carriers are attached to a stationary or rotating support frame. The well-known

Storage device has the disadvantage that the bobbins can not be taken over by the bobbin individually, but only in a multiple pack. In addition, the freely projecting coil support rods deform under the coil weight, which leads to positioning errors when loading and

Unloading leads. Storage capacity is also limited. Outsourcing and packaging is also complicated.

It is an object of the present invention to show a better storage facility.

The invention solves this problem with the features in the main claim.

The storage technology according to the invention has the advantage that the coils can be handled much better and more safely. Each coil can be accessed individually. Training as a rack storage has the advantage that despite individual access, the storage capacity is at least as large as in the prior art. The known positioning and conveying problems have been solved. Overall, there is a significantly improved storage technology combined with a very small space requirement.

In contrast to the prior art, the coils are stored horizontally on the coil carriers. It is advisable to design the coil carriers as pallet-like trays or so-called multitrays and to arrange several coils on them. The coils are individually stored on pins. This also facilitates unloading and, in particular, enables kinematically favorable access to the individual coil from above.

The bobbin can be moved from its convenient horizontal position to a vertical position using a turning device. The latter is advantageous for transport within the adjacent spinning areas for reasons of space. In addition, in the vertical position, the coils can be transferred from an external transport carrier to a coil carrier remaining inside the rack warehouse and circulating there.

The storage technology according to the invention also makes it possible to handle the coils sensitive to contact and contamination in a particularly gentle manner. For this purpose, it is advantageous to partition off the individual shelves from one another and thereby to avoid contamination. In addition, separate transport surfaces on the coil carriers prevent contamination.

For outsourcing, it is advantageous to separate the coils grouped on the bobbin again. The coils can be individually placed on so-called monotrays and transported individually. The isolation has the advantage that an inspection of the bobbins and also a sorting according to different criteria, for example quality, color, etc., can take place before packaging. Coils of different quality may be stored on the bobbin. As a rule, single-batches must be created during packaging. This can be done in a convenient manner via the separation. In addition, the coils can be grouped into new containers again by the monotrays and fed to the packaging device in a favorable number and arrangement. When separating, an upstream film packaging of the individual coils can also take place.

Further advantageous embodiments of the invention are specified in the subclaims.

The invention is shown in the drawings, for example and schematically. In detail show:

FIG. 4: a rotated end view of the transfer station according to arrow IV in FIG. 2,

Figure 5: an enlarged and detailed front view of shelves with bobbins and coils and

Figure 6: a side view of a monotray with coil.

The storage device (1) shown in the drawings is designed as a shelf storage for coils (3). Both

Spools (3) are preferably filament spools that are manufactured in spinning mills. In addition to the actual shelf storage, the storage device (1) also contains at least one transfer station (22) for connection to an external feeder (20) and, if appropriate, an unloading device (29). In addition, a conveyor (30), a packaging device (33), in particular a palletizer and optionally a film packaging device (33) can be provided on the output side. As FIG. 5 shows in detail, the individual coils (3) consist of a hollow cylindrical tubular coil core (4) made of cardboard or the like, onto which a winding (5) is wound on the circumference. The winding (5) consists of fibers, yarns or the like. In the direction of the central coil axis (6), the coil core (4) projects a bit beyond the winding (5) on both sides.

The coils (3) are held within the shelf storage (1) on coil carriers (2), which are preferably designed as pallet-like trays or so-called multitrays. Alternatively, they can have any other suitable shape. The coil carriers (2) preferably have a plurality of standing pins (7) or mandrels, onto which the coils (3) with the coil core (4) are attached. A large number of such individually movable coil carriers (2) are present within the rack store (1).

The shelf warehouse (1) has several shelves or rows of shelves

(16) with a large number of compartments (17). The compartments (17) are designed for horizontal storage of the coil carriers (2). Figure 5 illustrates this arrangement. The coil carriers (2) assume a preferably horizontal position, the pins (7) preferably standing vertically upwards in the storage position.

The coils (3) are individually attached to the pins (7), each pin (7) carrying only one coil (3). The length of the pins (7) is less than the coil core length. This creates a free space above the pins (7), through which the coil cores (4) can be grasped and handled from the inside. -

The pins (7) are arranged on widened support rails (8), on which the coil cores (4) rest on the bottom and with the coil axis (6) stationary. support. At the end, the support rails (8) are connected to the shelf (2) by a circumferential, stable frame (9). As illustrated in FIG. 1, eight pins (7) are arranged on a coil carrier (2), for example.

As illustrated in FIG. 5, the coil carriers (2) can have a bevel (10) on both side edges. On the one hand, this reduces the construction and storage height and, on the other hand, enables the arrangement to be spatially separated and at different heights

Transport surfaces (11, 12) for the movements within the compartments (17) and on other conveyor lines of the storage facility (1). On the stands of the shelves (16), support profiles (13) with slide rails (14) are arranged on each compartment (17). The slide rails (14) interact with the associated slide surfaces (11) on the underside of the folds (10). The running surfaces (12) for the other transport areas are arranged on the underside of the lower floor area of the coil carriers (2) lying next to them. By separating the

Transport or sliding or running surfaces (11, 12) reduce the abrasion and wear within the compartments (17) and the associated risk of contamination of the highly sensitive coils (3).

The compartments (17) are also partitioned off from one another. For this purpose, there are shelves (15) inserted or drawn in between the support profiles (13). The coils (3) are thus protected against dirt and dust.

Figure 5 also shows a particularly low-cost design of the support profiles (13). These are designed as folded and essentially L-shaped profiles. They have a downwardly extending longitudinal bulge on the horizontal leg, which receives the foot of the slide rails (14). In the simplest Embodiment, the slide rails (14) can be held in the clamp connection and optionally secured by screws. Bottoms (15) can be placed loosely and removably on an internally adjacent flange.

The slide rails (14) have a mushroom-like shape in cross section. They have guide surfaces on the top and on the inside, which interact with the fold (10). As illustrated in FIG. 5, this rail design enables the coil carriers (2) to be guided horizontally and laterally within the compartments (17).

The shelf storage (1) can be designed in different and arbitrarily suitable ways. Figures 1 to 4 show a preferred embodiment, each with two pairs of rack rows (16) and an intermediate alley (18), in which a rack conveyor (19) moves back and forth in the longitudinal direction and the coil carrier (2) laterally in the horizontal compartments ( 17) transported and removed. The shelf conveyor (19) is preferably rail-bound and has corresponding guides and drives for this. It has a side conveyor that can operate the adjacent rows of shelves (16) to the left and right. The shelf conveyor (19) can be remotely controlled or operated manually by a corresponding cross-warehouse and programmable control (not shown).

Within the rows of shelves (16), the bobbin carriers (2) are transported in a horizontal and horizontal position and stored or removed. Following the rows of shelves (16) there may also be horizontal feed and discharge conveyors (7, 28). At suitable locations, there may also be shelves (26) for temporary storage, for service purposes or the like. In spinning mills, the bobbins (3) are often transported with vertical bobbins for reasons of space. One or more transfer stations (22) are provided for connecting the rack storage (1) to one or more such external feeders (20). The feeders (20) consist, for example, of rail-bound overhead conveyors, to which vertically hanging transport carriers (21) are attached. The coils (3) with the horizontal or horizontal coil axis (6) are arranged on the latter.

As shown in FIGS. 1 to 4, the transfer station (22) has a turning device (24) and possibly also a transfer device (23). The turning device (24) serves to bring the coil carriers (2) from a vertical position into a horizontal position. With the transfer device (23), the coils (3) can preferably be transferred in one go from the transport carrier (21) to a ready-made coil carrier (2).

As can be seen from the side views from FIGS. 2 and 4, the feeders (20) are arranged on the ceiling and at a considerable distance from the floor. The turning device (24) has a stand (25) on which the turning mechanism can be moved up and down via a slide. The turning mechanism also includes suitable clamping means for holding and releasing the bobbin (2).

In the embodiment shown, the coils (3) are transferred from the transport carrier (21) to the coil carrier (2). Alternatively, with a corresponding system design, the coil carriers (2) can also circulate in the entire system area, so that the complete loaded coil carriers (2) are transferred from the feeder (20) to the turning device (24). For the transfer, the slide of the turning device (24) is located at the head of the stand (25) and holds the coil carrier (2) in a vertical position. The transfer device (23) is also arranged in a raised position and opposite. It has a plurality of pins or slides which, in the transfer position shown in FIG. 2, slide the coils (3) from the transport carrier (21) onto the pins (7) of the coil carrier (2).

After the transfer, the turning device (24) rotates the coil carrier (2) into the horizontal position shown in FIG. 4 with the coils (3) on top. Then the carriage of the turning device (24) moves down and transfers the coil carrier (2) to the bottom side

Feed conveyor (27) which extends along the one row of shelves (16). The feed conveyor (27) can have several intermediate or transport positions, on which the bobbin holder (2) can be stored or stowed. The feed conveyor (27) can e.g. be designed as a roller conveyor.

As illustrated in FIG. 1, the shelf conveyor (19) takes over the coil carriers (2) from the feed conveyor (27) and loads them into the shelf warehouse (1). A similar parallel output conveyor (28) is arranged opposite for the output of the coil carriers (2). A further output conveyor (28), e.g. a shuttle, connect.

The one or more output conveyors (28) can be connected to an unloading device (29) which removes the individual coils (3) from the coil carrier (2) and feeds them for further processing. The unloading device (29) can also use a suitable unloading robot

Have gripping tools that grip the coil cores (4) individually or in a pack at the free ends above and lift off the bobbin (2). The bobbin carriers (2) are moved and handled in a horizontal or lying position on the feed and discharge conveyor (27, 28) and inside the unloading device (29). The empty bobbin holder (2) can be returned to the rack storage (1) via suitable conveying paths and kept there at suitable collection and storage positions for the next use.

As shown in Figure 1, the unloading device

(29) a further conveyor (30) can be arranged. Individual coil carriers, so-called monotrays (31), are moved individually on this. Figure 6 shows the monotrays (31) in side view. The monotray (31) consists e.g. from a bottom-side circular transport disc (34) which is individually guided and moved on the conveyor (30) in a suitable manner. For this purpose, the conveyor can be designed as a drag conveyor, roller conveyor or the like. On the lying transport disc (34) there is a standing pin (35) on which the coil (3) with the

Inner sleeve can be plugged on. Each monotray (31) preferably carries only one coil (3). A coding (36) for identifying the monotrays (31) can be present on the transport disk (34) and / or the pin (35).

The monotrays (31) are also suitable and usable as replacements for the above-described coil carriers (2) or multitrays. They are then grouped into larger containers and held together with a suitable storage device.

When unloading, the unloading device (29) again separates the coils (3) grouped on the trays or multitrays (2) and transfers them individually to the

Monotrays (31). The monotrays (31) can be on the conveyor

(30) can be grouped again into new containers. In the course of the conveyor (30) may have other stations. An inspection according to quality and other differentiation criteria can be carried out on the individual coils (3). The individual coils (3) can also be sorted and forwarded sorted according to the type of branched conveyor. For example, the coils (3) can be sorted according to quality A or B. During the inspection, position corrections of the coils, small straightening work, etc. can also be carried out.

Another station on the conveyor is e.g. a film packaging device (32) is provided. In this, the individual coils (3) on the monotrays (31) are packed with a film, which e.g. as a lower third

Coils (3) are struck and then applied by suction to the top and bottom of the coils (3) or sucked into the coil core (4). In the case of film packaging, the spools can also be provided with a label (37) which contains the data and distinguishing features determined in terms of quality, color, etc. from the previous inspection. This data is managed by a cross-system control (not shown) and used for the further treatment of the coils (3) or the monotrays (31). The data of the tray coding (36) are also fed into the control. With this coding (36), with which the other coil carriers (2) or multitrays (2) are also equipped, the coil carriers can be identified and their path and their current movement and storage position can be tracked. This can be done via various test points (not shown), at which the coding and, if appropriate, also the label (37) are read by machine and the information is sent to the control. The unloading device (29) can also be followed by a packaging device (33). This is designed, for example, as a palletizer. The monotrays (31) are preferably sorted on the conveyor (30) and fed to the packaging device (32) according to type. The monotrays (31) can be grouped into the appropriate container size, eg as a five-pack or a nine-pack. The palletizer then takes over the coils (3) in groups and places them in layers on a provided pallet floor or stacks several layers on top of one another. The finished pallet is then wrapped with a shrink film or the like and optionally provided with strapping. The fully packaged pallet can then be removed.

Modifications of the exemplary embodiment shown are possible in various ways. The rows of bearings (16) can be standalone and each have their own shelf conveyor. The shelf conveyor can also take over the bobbin carriers (2) or the bobbins (3) from the feeder (20) without the special transfer stations (22). The feeder (20) can also be designed in another suitable manner and, for example in the simplest case, can consist of forklifts or other industrial trucks. It is also possible to transport and handle the coil carriers outside of the rack storage (1) in a lying position, which means that the turning device can be dispensed with. The design of the bobbin itself and the support and guide devices in the shelves are also variable. LIST OF REFERENCE NUMBERS
