NEW DESCRIPTION

Storage facility &iacgr;&ogr;

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

Such a storage facility is from GEBALD, Gregor:

"Handling, transport and storage system for cross-wound bobbins" in: Melliand Textilberichte, 2/1990, p. 103, 104. It is designed for highly sensitive filament bobbins that are manufactured in a spinning mill. The filament bobbins consist of a hollow bobbin core onto which a filament winding of yarn or fibers is applied. The bobbins are removed directly from the spinning machine by an automatic mobile palletizing and transport system, turned and palletized with suitable intermediate layers. The finished pallet is then taken to a high-bay warehouse, from which shipping also takes place. This arrangement has the disadvantage that the bobbins can only be removed from the spinning machine and palletized in pairs, and the palletizing device also constantly moves back and forth between the spinning machines. The pallet therefore contains spools of different origins from different machines, which causes problems with tracing any material or manufacturing defects. In addition, palletizing directly at the spinning machine takes a lot of time and limits the performance of the entire system. In addition, only the complete

Pallets, but not individual coil layers, are stored. Order picking must therefore take place before the high-bay warehouse and long before issue and dispatch.

DE 90 11 878 Ul shows a transport trolley for the intermediate transport of cops between a spinning machine and a winding machine. It has several drawers with pull-out pallet-like frames including mandrels for holding the cops. The frames are tied to the transport trolley and cannot move freely. The transport trolley is also not used for the stationary final storage of the cops, but only for their temporary transport.

Such transport carriages with horizontal coil carriers that hold the coils by means of vertical mandrels are known, for example, from US-A-2,466,861 or US-A-3,432,118.

In practice, the spools finished on the spinning machine are taken over by so-called doffers. In this process, several spools are transferred one after the other onto a horizontal mandrel of the doffer. The doffer then moves to a separating device, where the spools are transferred to plate-shaped transport carriers with horizontal mandrels and separated in the process. Such a transport carrier takes eight spools, for example. During the separation, the spools can be inspected, labeled and processed in other ways. The spools are then transferred again from the transport carrier in a storage facility.

Such a storage device known from practice has a large number of coil carriers, which consist of long horizontally arranged rods, onto which several coils are placed one behind the other with the coil cores

- 2a-

The spool carriers are attached to a stationary or rotating support frame. The known storage facility has the disadvantage that the spools cannot be taken from the spool carriers individually, but only in multiple packs. In addition, the freely projecting spool carrier rods deform under the weight of the spools, which leads to positioning errors during loading and unloading. Furthermore, the storage capacity is limited.

High-bay warehouses are known for other purposes in various designs from the state of the art, e.g. US-A-4,764,078 or EP-O 376 833 A1. DE 42 04 358 A1 discloses a storage and retrieval machine that can be moved within the high-bay warehouse and with which stored goods can be rotated in different axes. The storage technology is adapted to the goods to be stored. The state of the art is primarily concerned with relatively stable materials, such as paper or film rolls, carpet or linoleum rolls or the like. With these materials, the special problems of the highly sensitive filament spools do not exist.

It is an object of the present invention to provide a better storage device for filament spools.

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

The storage facility according to the invention has the advantage that the coils can be handled much better and more safely. Each coil can be accessed individually. The design as a shelf storage facility has the advantage that, despite individual access, the storage capacity is at least as large as with the state of the art. The previously known positioning and conveying problems are solved. Overall, this results in a significantly improved

Storage technology combined with very little space requirement.

The coils are stored lying on the coil carriers, which are designed as pallet-like trays and

accommodate several coils. The coils are individually mounted on pins. This also makes unloading easier and in particular enables kinematically favorable access to the individual coil from above. 10

Using a turning device, the bobbin carriers can be moved from their horizontal position, which is convenient for storage, to a vertical position. The latter is advantageous for transport within the adjacent spinning areas due to space constraints. In addition, in the vertical position, the bobbins can be transferred from an external transport carrier to a bobbin carrier that remains within the rack storage and circulates there.

The storage technology according to the invention also makes it possible to handle the spools, which are sensitive to contact and contamination, in a particularly gentle manner. For this purpose, it is advantageous to separate the individual shelves from one another and thus prevent contamination. In addition, separate transport surfaces on the spool carriers prevent contamination.

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

(Continued with page 3 of the original description)

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

Figure 2: a side view of the storage device according to arrow II of Figure 1;

Figure 3 : a front view of the storage facility

according to arrow III of Figure 2;

Figure 4 : a rotated front view of the

Transfer station according to arrow IV of Figure 2 and

Coil carriers and coils.

The storage facility (1) shown in the drawings is designed as a shelf storage facility for spools (3). The spools (3) are preferably filament spools that are produced in spinning mills. In addition to the actual shelf storage facility, the storage facility (1) also includes at least one transfer station (22) for connection to an external feeder (20) and, if necessary, an unloading device (29).

As Figure 5 shows in detail, the individual coils (3) consist of a hollow, cylindrical coil core (4) made of cardboard or the like, onto which a winding (5) is wound around the circumference. The winding (5) consists of fibers, yarns or the like. The coil core (4) protrudes on both sides in the direction of the central coil axis (6).

Piece beyond the winding (5).

The coils (3) are held within the shelf storage (1) on coil carriers (2), which are preferably designed as pallet-like shelves. Alternatively, they can also have any other suitable shape. The coil carriers (2) have one or more standing pins (7) or mandrels onto which the coils (3) with the coil core (4) are placed. Within the

A large number of such individually movable coil carriers (2) are present in the shelf storage (1).

The shelf storage (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) preferably take up a horizontal position, with the pins (7) in the storage position preferably standing vertically upwards.

The coils (3) are individually plugged onto the pins (7), whereby each pin (7) only carries one coil (3). The length of the pins (7) is smaller than the length of the coil core. 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 are supported by the coil axis (6). At the end, the support rails (8) are connected to the tray (2) by a stable frame (9) running around the entire circumference. As Figure 1 shows, eight pins (7) are arranged on a coil carrier (2).

As Figure 5 shows, 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 of 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). Support profiles (13) with slide rails (14) are arranged on the uprights of the shelves (16) on each compartment (17). The slide rails (14) interact with the associated slide surfaces (11) on the underside of the bevels (10). The running surfaces (12) for the other transport areas are arranged on the underside of the adjacent lowered floor area of the coil carriers (2). This separation of the transport or sliding or running surfaces (11, 12) reduces the abrasion and wear within the compartments (17) and . the associated risk of contamination of the highly sensitive coils (3) is significantly reduced.

■ The compartments (17) are also sealed off from one another. For this purpose, there are shelves (15) inserted or recessed between the support profiles (13). The coils (3) are thus protected from one another and are dirt and dust-tight.

Figure 5 also shows a particularly production-efficient design of the support profiles (13). These are designed as bevelled and essentially L-shaped profiles. They have a downward-projecting longitudinal bulge on the horizontal leg, which accommodates the foot of the slide rails (14). In the simplest design, the slide rails (14) can be held in place in a clamping connection and secured with screws if necessary. Bases (15) can be placed loosely and removably on an adjacent flange on the inside.

The slide rails (14) have a mushroom-like shape in cross-section. They have guide surfaces on the top and on the inside that interact with the bevel (10). As Figure 5 shows, this rail design enables horizontal and lateral guidance of the coil carriers (2) within the compartments (17).

The shelf warehouse (1) can be designed in different and arbitrarily suitable ways. Figures 1 to 4 show a preferred embodiment with two pairs of shelves (16) and an aisle (18) in between, in which a shelf conveyor (19) moves back and forth in the longitudinal direction and transports the coil carriers (2) laterally into the horizontal compartments (17) and removes them. The shelf conveyor (19) is preferably rail-mounted and has appropriate guides and drives for this purpose. It has a side conveyor that can serve the adjacent shelf rows (16) to the left and right. The shelf conveyor (19) can be remotely controlled or manually operated by an appropriate warehouse-wide and programmable control (not shown).

Within the rows of shelves (16), the coil carriers (2) are transported in a lying and horizontal position and stored or retrieved. Horizontal feed and output conveyors (7,28) can also be present next to the rows of shelves (16). In addition, shelves (26) for intermediate storage, for service purposes or the like can be present at suitable locations.

In spinning mills, the spools (3) are often transported using vertical spool carriers 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

consist, for example, of rail-mounted overhead conveyors to which vertically suspended transport supports (21) are attached. The coils (3) are arranged on the latter with a lying or horizontal coil axis (6).

As Figures 1 to 4 illustrate, the transfer station (22) has a turning device (24) and, if necessary, also a transfer device (23). The turning device (24) serves to bring the coil carriers (2) from a vertical position to a horizontal position. With the transfer device (23), the coils (3) can be transferred, preferably in one go, from the transport carrier (21) to a coil carrier (2) that is kept ready.

As can be seen from the side views in Figures 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 is arranged so that it can be moved up and down via a carriage. The turning mechanism also contains suitable clamping means for holding and releasing the spool carrier (2).

In the embodiment shown, the bobbins (3) are transferred from the transport carrier (21) to the bobbin carrier (2). Alternatively, with a corresponding system design, the bobbin carriers (2) can also circulate in the entire system area, so that the completely loaded bobbin carriers (2) are transferred from the feeder (20) to the turning device (24).

For transfer, the carriage 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 in a raised position and arranged opposite. It has

several pins or sliders which, in the transfer position shown in Figure 2, push the coils (3) from the transport carrier (21) onto the pins (7) of the coil carrier (2).

After the transfer, the turning device (24) turns the bobbin carrier (2) into the horizontal position shown in Figure 4 with the bobbins (3) on top. Then the carriage of the turning device (24) moves downwards and

&iacgr;&ogr; transfers the spool carrier (2) to the floor-side feed conveyor (27), which extends along one row of shelves (16). The feed conveyor (27) can have several intermediate or transport positions on which spool carriers (2) can be temporarily stored or accumulated. The feed conveyor (27) can be designed as a roller conveyor, for example.

As Figure 1 shows, the rack conveyor (19) takes the coil carriers (2) from the feed conveyor (27) and transports them to the rack storage (1). A similar parallel output conveyor (28) is arranged opposite to output the coil carriers (2). Another output conveyor (28), e.g. a shuttle, can be connected to this at the end.

The output conveyor(s) (28) can be connected to an unloading device (29) which removes the individual spools (3) from the spool carrier (2) and supplies them for further processing. The unloading device (29) can have a suitable unloading robot with gripping tools which grip the spool cores (4) at the free ends above, individually or in a pack, and lift them off the spool carrier (2). The spool carriers (2) are moved and handled in a horizontal or lying position on the feed and output conveyor (27, 28) and within the unloading device (29). The empty spool carrier (2) can be transported via suitable conveyor paths.

returned to the shelf storage (1) and kept there in suitable collection and storage positions for the next use.

Modifications to the embodiment shown are possible in various ways. The storage rows (16) can be independent and each have its own storage conveyor. The storage conveyor can also transport the coil carriers without the special transfer stations (22).

(2) or the coils (3) from the feeder (20) directly. The feeder (20) can also be designed in another suitable way and, for example, in the simplest case, consist of forklifts or other industrial trucks. It is also possible to transport and handle the coil carriers in a lying position outside the rack storage (1), which means that the turning device can be dispensed with. The design of the coil carriers themselves and the support and guide devices in the rack compartments are also variable.
