Abstract

The invention relates to a device and a method for storing spools (3), especially filament spools, comprising several spool carriers (2). According to the invention, the spools (3) are stored with an upright spool axis (6) in a shelf storage unit (1) with horizontal shelf compartments (17) for receiving individually movable spool carriers.

Description

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

Such a storage device is from DE-297 04 497-U1 known. It is for highly sensitive filament spools designed, which are manufactured in a spinning mill. The Filament bobbins consist of a hollow bobbin core a filament winding of yarn or fibers is applied. The known storage facility has a variety of individually movable pallet-like Coil carriers or so-called trays with several towering thorns that hold the coils along with the coil cores take up with stationary coil axis. The bobbin are stored in a shelf warehouse with horizontal compartments.

From the literature: Gebald G .: "Handling, transport and Storage system for packages "Melliand textile reports, international textile reports, Vol. 71, No. 2, February 1 1990, page 103/104, is another storage technology for Open-end packages known in a rotor spinning mill. The Completed bobbins are transferred from the spinning machine a mobile palletizing and transport system Intermediate pallet layers with a specified hole pattern filed. This makes several layers on top of each other a pallet formed that as a whole is a high bay warehouse and can be sent to a downstream shipping.

It is an object of the present invention to provide a better one Show storage facility.

The invention solves this problem with the features in the main claim.
The storage technology according to the invention 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.

The storage technology also has the advantage that the coils can be handled well and safely. On every spool can be accessed individually. Training as Shelf storage has the advantage that despite individual access the storage capacity is very large. Overall, it results an improved storage technology in connection with a very small space requirement.

The bobbins are stored horizontally on the bobbins. It is advisable to place several coils on the To arrange coil carriers. Here the coils are individual stored on pins. This also facilitates unloading and enables in particular a kinematically favorable Access to the single coil from above.

The coil carriers can be made out of a turning device their favorable horizontal position in a vertical Position. The latter is for transportation within the adjacent spinning areas Advantageous space. In addition, in the vertical position the coils from an external Transport carrier on one inside the rack warehouse remaining and circulating coil carriers there be handed over.

For outsourcing it is advantageous to put on the bobbin grouped coils again. The coils can individually put on so-called monotrays and can be transported individually. The isolation has the advantage that an inspection of the Coils and also a sorting according to different Criteria, e.g. according to quality, color, etc. can. There may be coils on the bobbin different quality stored. When packaging As a rule, single-batches must be created. This can be done in a convenient way via the separation respectively. The coils can also be moved through the monotrays again grouped into new containers and in a cheap Number and arrangement of the packaging device supplied become. When separating, there can also be one upstream film packaging of the individual coils occur.

In the subclaims are further advantageous Embodiments of the invention specified.

The storage device (1) shown in the drawings is designed as a rack storage for coils (3). Both Spools (3) are preferably filament spools, which are manufactured in spinning mills. The Storage facility (1) includes apart from the actual Shelf warehouse also at least one transfer station (22) to Connection to an external feeder (20) and optionally an unloading device (29). In addition can a conveyor (30), a Packaging device (33), in particular a palletizer and optionally a film packaging device (33) to be available.

As FIG. 5 shows in detail, the individual coils are made up (3) from a hollow cylindrical tubular coil core (4) made of cardboard or the like, on the circumferential one Winding (5) is wound. The winding (5) consists of Fibers, yarns or the like. Towards the central The coil core (4) protrudes on both sides of the coil core (4) Pieces beyond the winding (5).

The coils (3) are inside the rack warehouse (1) Coil carriers (2) held, preferably as pallet-like trays or so-called multitrays are trained. Alternatively, you can use one have any other suitable shape. The Coil carriers (2) preferably have several standing ones Pins (7) or spikes on which the coils (3) with the The coil core (4) can be attached. Within the Shelf stores (1) are a large number of such individually Movable coil carrier (2) available.

The shelf warehouse (1) has several shelves or rows of shelves (16) with a large number of compartments (17). The subjects (17) are for horizontal storage of the coil carriers (2) educated. Figure 5 illustrates this arrangement. The Coil carriers (2) take a preferably horizontal position a, the pins (7) preferably in the storage position stand vertically upwards.

The coils (3) are individually attached to the pins (7), each pin (7) carries only one coil (3). The length the pins (7) are smaller than the coil core length. Thereby there is a free space above the pins (7) over which the Coil cores (4) can be gripped and handled from the inside can.

The pins (7) are on widened support rails (8) arranged on which the coil cores (4) on the bottom side lie on and with the coil axis stationary (6) trim. The support rails (8) are through at the end a circumferential stable frame (9) for the tray (2) connected. As shown in Figure 1, e.g. eight pins (7) arranged on a coil carrier (2).

As shown in Figure 5, the coil carrier (2) can have a bevel (10) on both side edges. This on the one hand reduces the construction and storage height and on the other hand, enables the arrangement to be spatially separated and at different heights Transport areas (11, 12) for movements within the Subjects (17) and on other conveyor lines of the Storage facility (1). On the stands of the shelves (16) are on each compartment (17) support profiles (13) with slide rails (14) arranged. The slide rails (14) act with the associated sliding surfaces (11) on the underside of the Bends (10) together. At the bottom of the adjacent lowered floor area of the Coil carriers (2) are the running surfaces (12) for the others Transport areas arranged. By separating the Transport or sliding or running surfaces (11, 12) becomes the Abrasion and wear within the compartments (17) and the associated risk of pollution of the highly sensitive coils (3) significantly reduced.

The compartments (17) are also partitioned off from one another. To for this purpose are located between the support profiles (13) inserted or retracted floors (15). The coils (3) are therefore dirt and dustproof against each other protected.

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 projecting 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, if necessary, 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 warehouse (1) can be in different and any be designed in a suitable manner. Figure 1 to 4 show a preferred embodiment, each with two pairs related rows of shelves (16) and one intermediate alley (18) in which a shelf conveyor (19) reciprocates 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 for this corresponding guides and drives. It has one Side conveyor that adjoins to the left and right Shelf rows (16) can operate. The shelf conveyor (19) can by a corresponding cross-warehouse and programmable controller (not shown) can be controlled remotely or manually.

The coil carriers (2) are located within the rows of shelves (16). transported in a horizontal and lying position and outsourced. Following the rows of shelves (16) also horizontal feed and discharge conveyors (7.28) to be available. At appropriate points can also Shelves (26) for temporary storage, for service purposes or the like.

In spinning mills, the bobbins are made of space (3) often transported with vertical bobbins. For the Connection of the rack storage (1) to one or more such external feeders (20) are one or more Transfer stations (22) are provided. The feeders (20) consist for example of rail-bound Overhead conveyors on which vertically hanging transport carriers (21) are attached. The coils (3) are on the latter horizontal or horizontal coil axis (6) arranged.

As shown in Figures 1 to 4, the Transfer station (22), a turning device (24) and optionally also a transfer device (23). The Turning device (24) serves to remove the bobbin (2) to a vertical position in a horizontal position bring. With the transfer device (23) Coils (3) preferably in one go together Transport carrier (21) to a ready Coil carrier (2) are handed over.

As from the side views from FIGS. 2 and 4 can be seen, the feeders (20) are on the ceiling and arranged at a considerable distance from the ground. The Turning device (24) has a stand (25) on which the turning mechanism up and down on a sled drivable is ordered. The turning mechanism includes also suitable clamping devices for holding on and letting go the bobbin (2).

In the embodiment shown, the coils (3) are from Transfer the transport carrier (21) to the coil carrier (2). Alternatively, with a corresponding System design also the coil carrier (2) as a whole Circulate plant area so that a handover of the fully loaded coil carrier (2) from the feeder (20) to the turning device (24).

The carriage of the is for handover Turning device (24) on the head of the stand (25) and holds the bobbin (2) in a vertical position. The Transfer device (23) is also raised Position and arranged opposite. She points a plurality of pins or sliders, which are shown in FIG shown transfer position the coils (3) from Transport carrier (21) on the pins (7) of the coil carrier (2) slide over.

After the transfer, the turning device (24) turns the Coil carrier (2) in the horizontal shown in Figure 4 Layer with overhead coils (3). Then he drives Slide the turning device (24) down and passes the coil carrier (2) to the bottom Feed conveyor (27), which is along the one row of shelves (16) extends. The feed conveyor (27) can have several Have intermediate or transport positions on which The bobbin (2) can be stored or stowed can. The feed conveyor (27) can e.g. as a roller conveyor be trained.

As illustrated in Figure 1, the shelf conveyor takes over (19) from the feed conveyor (27) the bobbin (2) and loads them into the rack warehouse (1). For the issue of Coil carrier (2) is a similar one opposite parallel output conveyor (28) arranged. At this can another discharge conveyor (28), e.g. on Shuttle, connect.

The or the output conveyor (28) can be sent to a Unloading device (29) can be connected to the individual coils (3) from the coil carrier (2) and the Feeds further processing. The unloading device (29) can use a suitable unloading robot Have gripping tools that the coil cores (4) to the Grab free ends at the top or individually and lift off the bobbin (2). On the feeder and Output conveyor (27.28) and within the Unloading device (29) in the bobbin (2) in a horizontal or lying position, moved and handled. The empty bobbin (2) can be via suitable conveying paths be returned to the rack storage (1) and there at suitable collection and stock positions for the ready for the next mission.

As shown in Figure 1, the unloading device (29) a further conveyor (30) can be arranged. On this becomes individual coil carriers, so-called monotrays (31), moved individually. Figure 6 shows the monotrays (31) in Side view. The monotray (31) consists e.g. from one bottom-side circular transport disc (34) on the conveyor (30) in a suitable manner individually and is moved. The conveyor can be used as a drag conveyor, Be roller conveyor or the like. On the lying transport disc (34) 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). At the Transport disc (34) and / or the pin (35) can be Coding (36) for identifying the monotrays (31) to be available.

The monotrays (31) are also a replacement for the above-described coil carrier (2) or multi-trays and usable. They will then become larger accordingly Containers grouped and with a suitable device held together for storage.

The unloading device (29) sporadically during outsourcing again on the shelves or multitrays (2) grouped coils (3) and passes 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 station (30) may have other stations his. On the individual coils (3), one can Inspection for quality and others Differentiation criteria are made. The single ones Coils (3) can also be sorted and over Appropriately branched delivery routes be forwarded. Here, e.g. the Sort spools (3) according to quality A or B. In the Inspection can also correct the position of the coils, small straightening work etc. are carried out.

Another station on the conveyor is e.g. a Foil packaging device (32) provided. In this the individual coils (3) on the monotrays (31) with packed in a film, e.g. as a lower third Coils (3) struck and then suctioned to the top and Bottom of the coils (3) created or in the Coil core (4) is sucked in. With foil packaging can also label the coils with a label (37) that were determined during the previous inspection Data and distinguishing features according to quality, color etc. contains. This data is provided by a cross-plant control (not shown) managed and for the further treatment of the coils (3) or of the monotrays (31). Be in control the data of the tray coding (36) are also fed. about this coding (36), with which the others Coil carriers (2) or multitrays (2) are equipped, the coil carriers are identifiable and can be opened their path and their current movement and storage position be followed. This can be done through various inspection bodies (not shown) happen on which the coding and optionally also read the label (37) by machine and the information is given to the controller.

The unloading device (29) can also be a Packaging device (33) may be connected downstream. This is e.g. trained as a palletizer. On the conveyor (30) the monotrays (31) are preferably sorted and fed sorted into the packaging device (32). Here, the monotrays (31) can be fitted into the appropriate one Container size, e.g. as a five-pack or a nine-pack, be grouped. The palletizer then takes over Coils (3) in groups and put them on one provided or stacked in layers several layers on top of each other. The finished pallet will then covered with a shrink film or the like and if necessary provided with strapping. The done the packed pallet can then be removed.

Variations of the embodiment shown are in possible in different ways. The rows of bearings (16) can be self-sufficient and each has its own shelf conveyor exhibit. The shelf conveyor can be dispensed with special transfer stations (22) also the coil carrier (2) or the coils (3) from the feeder (20) directly take. The feeder (20) can also be in another be suitably designed and e.g. in the simplest Fall from forklifts or other industrial trucks consist. It is also possible to keep the bobbin outside of the rack storage (1) in a lying position transport and handle, which makes the Turning device can be unnecessary. Are variable also the design of the coil carrier itself and the Support and guide devices in the shelves.
