EP2179934B1 - Packaging device and system for mostly flat objects, such as lithium-ion cells - Google Patents

Description

The present invention relates to a packaging device and a packaging system for substantially flat objects, in particular valuable technical articles to be protected, such as, for example, lithium ion cells.

For packaging a technical object, it is conventionally in many cases initially wrapped or wrapped in a plastic film or bag and thus protected from dust and moisture. Then, the thus wrapped article is surrounded by a storage, which is formed in many cases of Styrofoam or molded Pappmaschee, and packed with or in the surrounding storage in a carton. The storage is used for stable positioning of the technical object within the outer carton. As a regularly shaped, usually rectangular outer packaging of the outer carton serves for juxtaposing and stacking and transport protection. In the packaging system with plastic film or bag, storage and outer carton, alternatively, the storage may be replaced by a packaging filling material, such as cardboard chips or plastic chips. A problem with this conventional packaging is that in many cases it is treated as a disposable packaging and disposed of after a single use. Another problem is the variety of different materials used, which are to be given after use, separated by material type in the waste recycling cycle. When stored after use, ie normally transport of the technical article for further use, the relatively large outer volume of the package, which is larger than the volume of the article to be packaged therein, presents another problem.

For the storage and transport of articles, such as technical devices, which are used in fixed places of use in large quantities or repeatedly used, as is the case for lithium-ion cells, in some cases, multiple packaging, so-called Trays, used. These multiple packages, especially trays, are reusable and can accommodate a variety of similar items. For this purpose, the multi-packs can have holders or insert molds which are matched to the shape of an item to be picked up. Such multiple packaging disadvantageously require in many cases as a dust cover and for easier handling or easy stackability a regularly shaped, for example, rectangular outer packaging.

In AU-B-17233/83 discloses a foldable package with reinforced side walls. This package has on its inside a contoured material to protect the contents of the package from shocks and hold. In US 4241829 discloses a folded cardboard package having on its inside a shock-absorbing layer of a polyurethane foam. The contents of the package are sandwiched and held in place by the polyurethane foam. In US 4253892 For example, a method and apparatus for making upholstered pouches is disclosed. These packaging bags have polypropylene padding layers intended to allow two padding layers to be welded together.

In view of the problems and disadvantages of the known packaging and packaging systems, it is an object to provide a technically automated loading and unloading variable reusable packaging system for product families of substantially flat articles, such as lithium-ion cells.

To solve the problem, a foldable packaging apparatus according to claim 1 is provided as described in detail below.

As claimed, a packaging apparatus is provided for packaging at least one substantially flat article, particularly a valuable engineering article, such as a lithium-ion cell. The term packaging is also to be understood here as the wrapping or wrapping of the article. The flat article may be packaged or arranged in particular in a horizontal position in the packaging device.

The packaging device comprises a bottom plate with at least one first at least partially rectilinear side edge and at least one first cover plate with at least one first, at least partially rectilinear side edge, which hinged to the first side edge of the bottom plate pivotally is. Thus, the cover plate between a closed position in which the cover plate at least partially covers the bottom plate, and an open position in which the cover plate of the bottom plate is not opposite, are pivoted.

According to the invention, the bottom plate or the at least one cover plate has a padding layer on one side. The padded side faces the article when the article is in the package and the at least one cover is in its closed position. Further, the cushioning layer is formed so that the article is slidably held in relation to a lateral displacement when the at least one cover plate is in the closed position and at least a portion of the object between the cover plate and the bottom plate is arranged.

The bottom plate is preferably formed so that the article can be safely stored thereon. For example, the bottom plate is provided with a padding or is formed in terms of their dimensions (length and width) greater than the dimensions (length and width) of the article to be packaged. This design of the bottom plate allows a technically automated introduction of the article in the packaging device. The formation of the packaging device with the substantially flat base plate and the cover plate hinged thereto, in particular in one piece, allows, in cooperation with the substantially flat article to be packaged therein, an overall flat configuration of the packaging device, good stackability, with virtually no loss or shrinkage Dead spaces are created and efficient space utilization in stacking for storing and transporting a plurality of packaging devices is achieved.

The bottom plate and the first or second cover plate and the cushion layers provided thereon are in particular substantially planar. Preferably, the bottom plate and the first and second cover plates are elastically flexible, so that they return resiliently to their original, substantially planar shape after a bending deformation.

Preferably, the cover plate is integrally hinged to the bottom plate, in particular by means of a fold. The cushion layer may be integrated in the bottom plate or the at least one cover plate or be firmly connected thereto. In this way, the packaging device is integral with said components as a whole, in other words, the packaging device has no loose parts. Therefore, the packaging device as such is complete and can easily be used multiple times or as reusable packaging.

Due to the pivotable articulation of the cover plate on the bottom plate arranged in the packaging device on the bottom plate object at least partially received between the bottom plate and the cover plate and are enveloped by the bottom plate and the cover plate when the cover plate is in the closed position: This allows one good protection, in particular all-round protection, for the packaged item.

Due to the overall flat configuration of the sandwich packaging apparatus, i. Bottom plate - flat object - cover plate, the packaging device is particularly suitable for applications in which the bottom plate is arranged substantially in a horizontal position when the packaging device is filled with the technical object, in particular when the packaging device in a vertical stacking arrangements of a plurality is stored by packaging devices.

For a secure or all-round protective packaging of the article, it is sufficient that the cover plate in the closed position, the base plate only partially, i. covered in a sub-area, the object finds room in this sub-area. Preferably, however, the cover plate in its closed position covers the bottom plate almost completely, so that substantially the entire surface of the bottom plate is available for depositing one or more objects to be packaged.

In one embodiment, the packaging device may have a second upper cover plate with a first at least partially rectilinear side edge, wherein the first side edge of the second cover plate at one of the first Side edge of the bottom plate opposite, second, at least partially rectilinear side edge of the bottom plate is pivotally hinged, so that the second cover plate between a closed position in which the second cover plate of the bottom plate at least partially covers, and an open position in which the second cover plate of the bottom plate not opposite, can be pivoted. Preferably, the second cover plate has a cushioning layer on one side, the cushioned side facing the article when the article is in the package and the second cover plate is in the closed position. As with the first cover plate, the article may be slidably held in relation to lateral displacement when the second cover plate is in the closed position and at least a portion of the article is disposed between the second cover plate and the bottom plate of the packaging device ,

The second cover plate makes it possible, inter alia, for two substantially flat technical articles to be packed independently in the packaging device, wherein the article is held non-slip at least in a partial area of the article between the bottom plate and the first cover plate and the second article is at least held in place a portion between the bottom plate and the second cover plate is held non-slip.

With the second cover plate, which is provided in addition to the first cover plate, it is also possible to accommodate a relatively large technical object between the bottom plate on the one hand and the first and second cover plate on the other hand and to position it non-slip. For this purpose, preferably the first cover plate and the second cover plate are formed so that they substantially completely cover an object received in the package and in particular almost completely cover the bottom plate together when the first and second cover plate are each in their closed position.

In order to form the non-slip support with respect to a lateral displacement, the article in the package may be held in a clamping position between the cushion layer disposed on a cover plate and the cushion layer disposed on the bottom plate. The at least one cover plate or the Base plate can be flexible, in particular resilient or flexible elastic. Thus, in arranging the object between the bottom and the cover plate, when the at least one cover plate is in its closed position, a compressive force causing the clamping can be generated by the elastic restoring force of the plate or plates.

To improve slip resistance, the cushion layer has a one-sided anti-skid coating. The coated side faces the article when the article is received in the package and the at least one cover plate is in the closed position. The anti-slip coating may be formed of a rubbery material. It can also be formed by applying a friction-enhancing coating to the cushion layer. In particular, the anti-slip coating may have an adhesive layer for releasably fixing the article when it is in contact with the layer at least in a partial area.

The non-slip support in relation to a lateral displacement can also be achieved by forming on the cushion layer of the bottom plate and / or on the cushion layer of at least one cover plate a pocket for receiving, in particular for pushing in and pulling out the object. The bag can be closed on two opposite sides. At a third, the opposite side connecting side, the bag may also be closed or it may alternatively be arranged a snap closure. At a fourth, open, the two closed sides also connecting side preferably a snap closure is formed. When the article is pushed into the pocket, it is fixed by the pocket with respect to a lateral displacement, in particular with respect to a displacement towards the closed sides of the pocket and possibly towards the flap-closed sides of the pocket.

The first cover plate, optionally a second cover plate and the bottom plate may each have at least one recess formed on at least one side edge of the respective plate. Preferably, the at least one recess in the bottom plate is substantially congruent with a corresponding recess in the first and second cover plates, respectively, when the first and second cover plates are in their closed position. At least one recess in the bottom plate may be formed at a corner of the bottom plate. The bottom plate can also have two recesses formed at diagonally opposite corners. Congruent to the one or more recesses in the bottom plate, the first and second cover plate having correspondingly arranged recesses. The recesses serve to allow a lying packaging device, especially if it is arranged between lateral walls, to be easily picked up and lifted by engaging a tool or the fingers of a user's hand.

The cushioning layer may be formed of a soft material that is integrally formed on the bottom plate or the cover plate or applied to the bottom plate or cover plate. In particular, one, in particular respective, cushion layer may be formed as an air cushion film layer. Thus, the article is resiliently received when placed on the padded base plate and protected without risk of scratching and against mechanical shock from the outside in the packaging device.

The at least one cover plate can be integrally connected by a fold or folds with the bottom plate and hinged in this way pivotally. If a single fold is provided and if the at least one cover plate is brought into the closed position, wherein between the cover plate and the bottom plate of the object to be packaged, then the article presses due to its finite thickness in the cushion layer on the bottom plate and / or the cushion layer of the cover plate and is fixed in this way. A respective fold is preferably formed so that the cover plate with respect to the bottom plate from the closed position by an angle of at least 90 degrees, preferably 135 degrees and even more preferably at least 180 degrees can be pivoted to an open position.

As an alternative to the one fold, the at least one cover plate can be integrally connected to the bottom plate by means of two folds arranged at a predetermined spacing. In this case, in particular, the distance of the two folds can be selected so that it corresponds to the height of the packaging with an accuracy which substantially corresponds to a thickness of the bottom plate or the cover plate when the cover plate is in its closed position.

In particular, each of the two folds may be configured such that the cover plate can be pivotally opened with respect to the bottom plate by an angle of at least 45 degrees, preferably 60 degrees and more preferably at least 90 degrees, when the cover plate is out of its relative to the bottom plate pivoted closed position in an open position. When the cover plate is in its closed position, the area between the two folds can form a side wall of the packaging device. By forming two folds, the packaging device can also be adapted for packaging or picking up a relatively thick object, in particular without the bottom plate and / or the at least one cover plate being subjected to a strong bend.

The packaging device may be configured such that when a respective cover plate is in its closed position, a wrapped space formed between the respective cover plate and the bottom plate is thermally insulated and / or electrically insulated with respect to an environment of the packaging is. In particular, the bottom plate or the at least one cover plate for thermal insulation may comprise a reflective metal layer. In particular, the metal layer may be electrically insulated from the side of the cushioning layer facing the article when the article is received in the package and the at least one cover plate is in the closed position. For electrical insulation, the padding layer itself can be formed from an electrically insulating layer, in particular a plastic layer. Alternatively or additionally, in addition to Padding layer may be an electrically insulating layer in the packaging device integrated so that the electrically insulating layer completely envelopes an inserted in the packaging device object when the at least one cover layer and the cover layers are in their closed position.

The packaging device may additionally have an RFID transponder with a storage device connected thereto. The storage device may be designed such that data with information such as logistical, technical or material-economic information can be stored therein or stored therein. Logistic information may include, for example, the manufacturing location and date of manufacture of the item, the delivery location and delivery address of the item, and technical information about the item, such as a type designation, type number, serial number, specifications, and the like. Material economic information may include, for example, the number of items packaged in the packaging device, an order date, a packaging date or a delivery date. The storage of such information in the storage device can preferably be effected during automated filling of the packaging device. About the RFID transponder, which can operate as a receiver or transmitter, information can be received from an external transmitter or sent to an external receiving device and thus a data or information exchange, especially a bidirectional data or information exchange, take place , Thus, a memory content of the memory device may be updated, for example, when a first or another object is received in the packaging device, or when an object is removed from the packaging device, when the packaging device is a spatial threshold, such as a factory gate or a Lagerstorentor or a supplier receipt happens. By means of the RFID transponder and the storage device connected thereto, a material-economical material flow along a material flow chain from production to delivery or use can be automatically monitored and in particular also controlled.

The packaging device may also include a shock sensor for detecting a mechanical impact or an acceleration acting on the packaging. In particular, the shock sensor or a signal evaluation device operatively connected thereto can detect that the acceleration is greater than a predetermined acceleration limit value. The packaging device may also include a temperature sensor, a humidity sensor and / or a sensor for measuring an electric or magnetic field. By monitoring the measurement signals generated by these sensors (shock sensor, temperature sensor, etc.), it can be tracked whether, during a certain period of time, for example during transport, inside the packaging device there is a high load on the packaged article, e.g. Shock, high temperature, high humidity, a strong electric or magnetic field, has occurred or not.

The RFID transponder with the memory device or the shock sensor or a respective other of the aforementioned sensors, in particular together with, for example, in addition to a recorded between a cover plate and the bottom plate object in particular be arranged non-slip when the cover plate is in its closed position , Alternatively or additionally, the RFID transponder with the storage device or shock sensor or temperature sensor or a respective other sensor to the bottom plate or a cover plate be secured so that the thickness or height of the packaging at the point where the transponder or the sensor is mounted, not higher than the thickness of the packaging, when the article is received in the packaging between the bottom plate and a cover plate. For example, the RFID transponder with the storage device or the shock sensor or the temperature sensor or a respective other sensor may be arranged in a recess of the cushion layer and / or in a recess of the bottom plate or the cover plate.

A dehumidifying agent, such as silica gel, may be provided in the packaging device. The dehumidifying agent may be provided on one side of at least one cushioning layer, the cushioned side of the article facing, when the object in the package and the at least one cover plate is in the closed position. In particular, the dehumidifying agent may be provided in a moisture-permeable pocket formed on the side of the cushioning layer or in the form of particles applied to the surface on the side of the cushioning layer. The dehumidifying agent absorbs moisture and thus dehumidifies the atmosphere in the space in which the article is received in the packaging device when the at least one cover plate is in the closed position.

According to another aspect of the invention, as claimed, a packaging system is provided for receiving and securely transporting a plurality of substantially flat articles, particularly valuable engineering items, such as lithium ion cells. The packaging system comprises at least one packaging device as described above and a picking device for receiving a plurality of packaging devices as described above. The pick-up device is designed so that a respective packaging device can be inserted into the pick-up device and / or removed from it. Preferably, in the packaging system, the plurality of packaging devices are arranged parallel to each other. With such a packaging system, a plurality of packaging devices may be avoided while avoiding large dead spaces, i. with effective use of space, stored or transported.

In one embodiment of the packaging system, the pick-up device is a chest which is essentially open on its upper side and in particular closable. The chest is designed so that a respective packaging device can be inserted through the open top of the chest into the chest and removed from the chest or that in the chest a variety of packaging devices can be stacked.

The Figures 1A . 1B and 1C 14 show perspective views of an embodiment of a packaging device 10 according to the invention, each with variously inserted, substantially flat, articles 12, 12 'and 12 "to be packaged, The packaging device 10 comprises a rectangular bottom plate 14 having a first side edge 42 and a first side edge 42 The first cover plate 20 is pivotally connected along its first side edge 46 by means of a fold on the first side edge 42 of the bottom plate 14 and integrally The second cover plate 30 is hinged along its first side edge 48 by means of a fold to the second side edge 44 of the bottom plate and integrally connected to the bottom plate 14. A cushion layer extends continuously The padding layer thus comprises three subregions 22, 16 and 32 which comprise the padding layer 22 of the first cover plate 20, the padding layer 16 of the bottom plate 14 and the padding layer 32 of the second Form cover plate 30. The cushioning layer has a length which is substantially equal to the sum of the partial lengths of the regions on the first cover plate 20, the bottom plate 14 and the second cover plate 30. A width of the cushioning layer is smaller than the width of the bottom plate 14 and the first and second cover plate 20, 30, so that on both sides of the above the first cover plate 20, the bottom plate 14 and the second cover plate 30 extending cushion layer on the plates one in each case Side strips 24 and 34 is formed, which is not covered by the cushion layer.

On a respective side strip 24 or 34 of a respective cover plate, a closure device is provided by means of which a respective cover plate can be fixed in the closed position and released again. The closure device is, for example, a hook-and-loop fastener device or an adhesion closure, wherein the side strips 24 and 34 of the first and second cover plates 20 and 30 respectively are the counterpart of the closure device on the side strip 18 of the bottom plate is arranged. In the case of a hook-and-loop fastener, for example, the loop-like closure elements and on the side strips 24 and 34 the hook-like closure devices are arranged on the side strip 18, or vice versa. In the case of an adhesion closure, the adhesive layer is provided on the side strips 24 or 34 and the corresponding prepared non-adhesive layer is provided on the side strip 18, or vice versa.

In the Fig. 1A is arranged on the bottom plate 18, a relatively large substantially flat object 12. In Fig. 1B is on the bottom plate 14 a in comparison to the in Fig. 1A shown item smaller substantially flat object 12 'stored. In the Fig. 1C are two objects 12 "arranged side by side on the bottom plate 14, wherein a respective cover plate 20 and 30 in the closed state, the corresponding object 12" completely covered.

In the in Fig. 1 shown embodiment of the packaging device is formed on the bottom plate a pocket for receiving, in particular pushing in and out of the article. As in Fig. 1A Shown by the dashed line, a pocket 50 is formed by three closed sides and an open side extending along the side strip 18 of the bottom panel 14 for loading with the article 12 Fig. 1B On the bottom plate 14 a pocket 50 'for receiving the object 12' is formed. The bag 50 'may be used alone or in addition to at least one other bag, such as the one shown in FIG Fig. 1B shown pocket 50 and / or other pockets (not shown) may be formed on the bottom plate 14.

A respective pocket has two opposed, closed side edges and additionally a third, the two closed side edges connecting, third closed side edge, such as for the pocket 50 in Fig. 1A and the pockets 50 and 50 'in Fig. 1B shown. A respective pocket has a flap on an open side, such as the in Fig. 1B shown folding envelope 51 of the bag 50, which can additionally serve as a folding envelope for the pocket 50 '. A respective folding envelope can be pivoted into a closing and an opening position. In this case, in the opening position, the side of a bag for pushing in or out of the object Approved. In the closing position, the closed by the folding envelope side of the bag is closed, thus preventing slipping out of an inserted in the bag item from the bag.

As an alternative to or in addition to pockets on the base plate, pockets, in particular with flap closures, can also be provided on one or both cover plates. In Fig. 1B In addition to the pockets 50 and 50 'on the bottom plate 14 on the first cover plate 20, the device 10 has a pocket 52 with an envelope flap 53 and on the second cover plate 30 a pocket 54 with an envelope flap 55.

As in the Figures 1A . 1B and 1C the packaging device is suitable for packaging a variable size article (as shown in FIGS Figures 1A and 1B shown), or of two objects (as in Fig. 1C shown), or even three or more objects (not shown), as long as the objects on the bottom plate 18 can be arranged side by side.

Fig. 2 shows a perspective view of a packaging device 10 with a bottom plate 14 and a cover plate 20 which is hinged with its first side edge 46 on a side edge 42 of the bottom plate 14 pivotally.

In Fig. 2 For example, the first cover plate 20 and the bottom plate 14 have a substantially equal width measured along the side edges 42 and 46, respectively. The length of the cover plate 20, the in Fig. 2 is indicated by the dimension "I", is preferably substantially equal to a length of the bottom plate 14, which in Fig. 2 indicated by the dimension "L". However, the length of the cover plate 20 may also be shorter than the length of the bottom plate 14, so that when the cover plate 20 is in the closed position, on the bottom plate 14, a strip-shaped portion (not shown) is formed extending along the side edge 44 of the bottom plate extends and which is not covered by the cover plate 20. For example, on or on the side panel, carrying devices or an engaging device, such as a recess 60, as in FIG Fig. 6A shown to be provided.

Fig. 3 shows a packaging device 10 according to the invention with a bottom plate 14 and two cover plates, namely a first cover plate 20 and a second cover plate 30. The first cover plate 20 is hinged along its first side edge 46 at a first side edge 42 of the bottom plate 14 pivotally. The second cover plate 30 is hinged along its first side edge 48 at the first side edge 42 opposite the second side edge 44 of the bottom plate 14 pivotally. The first and second cover plates 20 and 30 respectively have a width measured along their respective side edges 46 and 48 which is substantially equal to the width of the bottom plate 14 measured along the side edges 42 and 44 of the bottom plate, respectively. The first and second cover plates 20 and 30, respectively, have a length I ₁ and I ₂ , respectively, taken together preferably corresponding to an overall length of the bottom plate 14 such that when the first and second side plates 20 and 30 are in their closed positions, the Base plate 14 is substantially completely covered by the cover plates 20 and 30.

If the first and second cover plates 20 and 30 substantially completely cover the bottom plate 14, then an article 12 or 12 'inserted into the packaging device 10 may also extend beyond a portion covered by a single cover plate, as in FIGS Figures 1A and 1B are almost completely enveloped by the first and second cover plates 20 and 30 when the sum of the lengths I ₁ and I _{2 of} the first and second cover plates is substantially equal to the length L of the bottom plate 14, as in FIG Fig. 3 shown.

The FIGS. 4 and 5 show cross sections through a packaging device 10 in the closed state, wherein in each case an object 12 is inserted in the packaging device 10. In Fig. 4 To the bottom plate 14, the first cover plate 20 is hinged by means of a fold 70 and the second cover plate 30 by means of a fold 70 'pivotally. The bottom plate 14 and the first and second cover plates 20 and 30 each have an elastic bendability. With the article 12 loaded into the packaging apparatus 10, when the first and second cover flaps 20 and 30 are brought into their respective closed positions and pressed flat in contact with one side of the article 12, they bend the first and second cover plates 20 and 30 and / or the bottom plate 14 near the edges of the article 12.

In the in the FIGS. 4 and 5 The packaging layer 10 shown, the cushion layer is formed by an air cushion layer 66 with a plurality of air bubbles or air bubbles. In the region in which the object 12 is inserted between the cover plates and the bottom plate, the cushion layer presses a little, while the cushion layer in the region in which the object 12 does not extend in a relaxed, less or not pressed State is. By virtue of the cushioning layer being pressed in the regions in which the article 12 extends, the article 12 is held non-slip with respect to a lateral displacement relative to the plates 14, 20 and 30, respectively.

In the in Fig. 5 the embodiment of a packaging device 10, the first cover plate 20 by means of two folds, namely a first fold 72 and a second fold 74 and, accordingly, the second cover plate 30 by means of two folds, namely a first fold 72 'and a second fold 74', on the Base plate 14 hinged pivotally. The respective first and second folds 72 and 74 or 72 'and 74' are arranged parallel to each other and at a predetermined distance. The distance between the first and second folds 72 and 74 or 72 'and 74' corresponds substantially, ie, to an accuracy corresponding to a thickness of the first and second cover plate 20 and 30, the height of the packaging device 10, if the two Cover plates 20 and 30 are in the closed position. The distance between the first and second folds 72 and 74 or 72 'and 74' is adapted to the thickness of an article 12 to be packaged and chosen so that the distance is almost or approximately equal to the sum of the thickness of the base plate 14 with cushion layer, the thickness of the article 12 and the thickness of the first and second cover plate 20 and 30 with a cushion layer. However, the distance between the first and second folds 72 and 74 or 72 'and 74' is not less than the sum of the thicknesses of the bottom plate 14 without cushioning layer, the thickness of the article 12 and the thickness of the first and second cover plate 20 and 30 without poster layer. If the distance between the two folds 72 and 74 or 72 'and 74' is selected in the above-described interval, it is possible that the cushioning layers of the cover plate and / or the cushion layer of the Give ground plate yield and be pressed when an object 12 is inserted between the bottom plate and located in their respective closed position cover plates and is held non-slip by the pressing against lateral slipping.

The Figures 6A and 6B 5 are plan views of a packaging device 10 according to the invention, which is arranged or inserted as the uppermost in a stack of packaging devices between side walls 68, 68 'and 68 "between the side walls 68, 68' and 68" is one or a plurality of Packaging devices stacked one above the other and secured against falling stack.
