Description

The invention relates to a transfer device as part of a stacking container or for use in a stacking container, wherein the stacking container is configured to form a stacking arrangement with at least one further stacking element, in particular stacked container, onto which the stacking container can be stacked with its underside or onto the top side the stacking container is stackable, wherein the transmission device for transmitting data and / or energy bus interfaces, which form a bus connection between the stack containers in the stacked state of the stack container, wherein the bus interfaces each at least one electrical coil for inductive energy transfer from or to the stack container stacked or stacked under the stack container stacking element.

A transmission device of this kind is for example in DE 10 2014 010 377 explained.

In contrast, an improved concept of energy transfer for stacking containers will be proposed.

To achieve the object, it is provided in a transmission device of the aforementioned type that the transmission device has a machine interface connected to a line arrangement between the bus interfaces to an electrical energy supply of a hand-held machine tool or energy storage device for a hand-held machine tool received in the stack container.

The invention further relates to a stack container comprising a congestion receiver and a transmission device of the above type.

To achieve the object, a stack arrangement comprising at least two stack elements, each with a transmission device is provided. The stack elements comprise, for example, stack containers which can be stacked on one another. However, one of the stacking elements can also be a stacking base onto which a further stacking element, in particular a stacking container, can be stacked or under which another stacking element, in particular a stacking container, can be stacked.

The line arrangement connects the bus interfaces with each other. Thus, for example, current can flow from one coil to the other coil.

It is a basic idea that the machine interface receives electrical energy from the coils of the transmission device. The coil arrangement of the bus interfaces allows contactless or wireless transmission of energy from one stacking element to the next stacking element. In the stacking element itself, no conversion of the current or voltage for retransmission of energy to an adjacent, for example stacked or stacked, stacking element is necessary. Thus, a very simple structure is possible.

It is preferably provided that the coils of the bus interfaces of the transmission device are electrically connected to one another without an intermediate inverter or rectifier.

The coils of the bus interfaces are suitably connected to each other in series or in parallel with each other.

An output voltage of the machine interface is preferably significantly smaller than a voltage present at the electrical coils of the bus interfaces. For example, the voltage of the electric coils is at least twice as large as the output voltage of the machine interface. For example For example, the voltage range of the machine interface is about 20-22V, a typical charging voltage for charging battery packs, while the voltage of the bus interface coils is about 48V. Thus, a particularly effective energy transfer from stacking container to stacking container is possible while providing typical in manual power tools smaller voltages at the machine interfaces.

It is preferred if a resonant inductive coupling between the stack elements is realized. For example, it is provided that the electrical coils of the bus interfaces are connected to a capacitor such that a resonant circuit is formed with a resonant frequency.

It is advantageous if the coils are connected in parallel with at least one electric capacitor. Alternatively, a serial circuit of the capacitor would be possible with the coils.

The resonant frequency of an inductive coupling of the transmission device with at least one stacked or stacked stacking element can correspond, for example, to the resonant frequency of only one stacked or stacked stack element, for example another stacking container or any other stackable or stackable stackable element, for example a plate. For example, it is possible that the resonance frequency of the transmission device corresponds to that of a corresponding coupling device for providing vibrations for the transmission device.

However, the tuning to the resonance frequency can refer not only to a respectively stacked or stacked stack element, but also to the arrangement of several or all stacked stack elements. Thus, for example, it is possible for an overall system, which contains a plurality of stack containers or stack elements, to have a predetermined resonant frequency to which the transmission device is tuned.

The machine interface is suitably connected in series to the capacitor. One could also call the capacitor a compensation capacitor.

However, the machine interface does not have to be connected directly to the capacitor or the compensation circuit. It is also possible to provide energy conditioning, for example for the machine interface and / or the communication interface explained below.

It is preferred if the transmission device has a communication interface configured in particular as a communication module for transmitting data from and / or to the handheld power tool or energy storage device and / or the machine interface accommodated in the stacking container. Thus, for example, charging states, temperatures, powers, fault information, power, can be transmitted to the identification identifiers and the like, for example, to a stacking base of the stacking arrangement or another operating device.

The communication interface can be designed, for example, for communication via the bus connection. However, it is preferred if the communication interface for wireless communication with a further stack element of the stack arrangement, for example the stack base of the stack arrangement, is designed independently of the bus connection. In particular, it is preferred if the wireless communication can take place at a low energy level or a low energy level. For example, the energy level of the wireless communication is preferably only a maximum of half the energy level on the bus connection. Thus, for example, via Bluetooth or other such wireless communication, for example, a state of charge may be transmitted from the energy storage device or handheld machine tool to the stacking base. The bus connection is not burdened thereby and / or not required.

In the context of the invention is also a stacking base for a transmission device according to the invention. The stacking base expediently has a power generating device for providing an alternating current for the electrical coil. For example, the power generation device comprises an oscillator.

The power generating device is preferably designed to generate the alternating current at a resonant frequency of the coil arrangement of the transmission device of the stacking container. For example, a capacitor or compensation capacitor of the power generating device is connected in parallel or in series with the coil of the stack base.

It is preferred if the respective resonance frequencies of the transmission devices and / or the stack base are substantially the same, that is to say that a maximum of 5-10%, in particular only 1% to 3%, differ from each other, preferably identical.

A resonant frequency of the power generating means of the stacking base is preferably adapted or adaptable to the resonant frequency of the stacking container that communicates with the stacking base, and in particular is to be energized thereby. The resonance frequency of the stack base thus expediently corresponds to at least one stacked or stacked stacking container. But it is also possible that the resonant frequency of the stacking base is set or adjustable so that it corresponds to the resonant frequency of a plurality of stacking containers, for example, two or all stacked on the stack base and / or two or all under the stack base untergestapelter stack container. Thus, the resonance frequency of the stack base can be matched to, for example, only one stacked or stacked stack element or also to a plurality of stack elements, in particular all stack elements of the stack, in or below or on which the stack base is arranged.

Preference is given to a stack arrangement in which the coil arrangements of at least two stacking elements, in particular two stacking containers and / or a stacking container and a stack base, have substantially the same resonant frequency, in particular with a maximum of the above-mentioned deviation from each other.

The power generating device is expediently designed to adapt a current strength of the alternating current and / or to adapt a frequency of the alternating current as a function of a respective power consumption of the stacking containers of the stacking arrangement. For this purpose, it can, for example, use the communication interface explained below, which communicates with, for example, a machine interface of the power consumer, namely the stack base. The communication interface can also communicate directly with a communication interface of the stacking container or the transmission device of the stacking container, for example, to obtain data on a state of charge of the energy storage device and / or hand-held machine tool.

Namely, the stacking base preferably has a communication interface for communication with a communication interface of the transmission device, which is provided for transmitting data from and to the handheld power tool or energy storage device and / or the machine interface accommodated in the stacking container. It is preferred that these communication interfaces do not communicate with each other via the bus connection, for example communicate directly with each other wirelessly (Bluetooth or the like). However, it is also possible for the communication interfaces of the stack base and the stack container to communicate with one another via the bus connection.

The stack base may also form a stack container or be provided by a stack container. In this case, the stacking base has, for example, a congestion receiver, in which the hand-held machine tool or a hand-held machine tool as well as an energy storage device can be accommodated or which is provided for receiving a hand-held machine tool and / or an energy storage device.

It is particularly advantageous if the electrical coils of the transmission device are arranged on the top side and the bottom side of the stacking container when the transmission device is arranged in the stacking container. The or at least one of the coils can be integrated in the stacking container or the body of the stacking container, for example in its bottom wall or lid. However, the arrangement of the transmission device explained below is preferred in or on a container insert which can be inserted into the actual stacking container. Therefore, it is thus possible for one coil to form part of a stack container while the other coil is arranged in the container insert. However, all components or all coils of the transmission device can also be arranged on or in the container insert

Appropriately, it is provided that a container body of the stacking container has a limited by a bottom wall on its underside and the bottom wall to its top peripheral walls limited storage space for receiving a container insert which a transport receptacle for transporting an electric or pneumatic hand-held power tool or an accessory having such hand tool machine

The transfer device is advantageously held in the container insert or forms part of the container insert, so that the transfer device can be used together with the container insert as a transmission module in the congestion recording and the bus interfaces of the transfer device are held by the container insert with respect to the Behälterkorpusses in position so that a Bus interface are arranged at the bottom of the stacking container to a stacked under the stacking container stacking element and a bus interface at the top of the stacking container to a stacked on top of the stacking container stacking element.

A basic idea provides that the components of the transmission device are not components of the stacking container, but instead form a transmission module with the container insert. Thus, the stack container so to speak be designed as a simple carrying container or hollow body, which does not need any electrical components or at least the bus interfaces not even has. The electrical equipment or the equipment with the bus interfaces is provided by the transfer module for the stack container. Thus, simple, so to speak conventional stacking container can be used, which are so to speak through the container insert with the transmission device for the preparation of the bus connection, so to speak.

The stacked or stacked stacking element of the stacking arrangement may, for example, be a further stacking container in the sense of the invention, ie a stacking container, which is preferably equipped with a container insert and transfer device of the above type. But it is also possible that this further stacking container similar to the stacking container of the aforementioned earlier patent application DE 10 2014 010 377 is configured, ie that one or more bus interfaces are arranged directly on the container body or the lid of the container body. However, the stacked stacking element can also be formed by a stacking base, which is not provided for transporting hand-held machine tools or the like other goods. The stacking base can be, for example, a vacuum cleaner or else a stacking element that can be arranged, for example, in a rack or other tray, onto which the stacking container equipped or designed according to the invention can be stacked up.

The transport receptacle can be provided in the simplest case that, for example, accessories or wearing parts of the hand-held machine tool can be transported. However, the transmission device also provides valuable services in this case because it can produce the bus connection to a stacked or stacked stack element.

Preferably, however, the transport receptacle is configured as a machine receptacle or has a machine receptacle, wherein the machine receptacle for at least partially positively receiving the hand-held machine tool or an electrical energy storage device for electrical power supply of the hand-held power tool is provided or designed. Thus, therefore, the hand-held power tool or the energy storage device can advantageously be transported on the basis of the container insert. It is also possible that the machine receptacle is provided for receiving the hand-held power tool with energy storage device arranged thereon. In the energy storage device is, for example, a battery pack or other energy storage. The energy storage device expediently has a plurality of storage cells.

The transmission device preferably has a machine interface for transmitting data and / or energy to or from the hand-held power tool or the electrical energy storage device. The machine interface is preferably designed for a voltage adjustment. For example, the machine interface includes a power supply.

The machine interface is connected to at least one of the bus interfaces, preferably both bus interfaces. This compound is e.g. implemented via electrical lines. The connection can also be wireless.

The machine interface expediently has at least one electrical contact or a contact arrangement with a plurality of electrical contacts, for example sockets, plug-in projections or the like, for establishing an electrical connection with the hand-held power tool or the energy storage device. However, the machine interface may alternatively or additionally comprise transmission means for the wireless transmission of data and / or energy. On the basis of the transmission means, for example an electrical coil, for example, data from the hand-held power tool or the energy storage device can be received or transmitted to it. Furthermore, it is possible to transmit electrical energy wirelessly by means of the transmission means to the hand-held power tool or the energy storage device.

It is preferred if the machine interface is arranged stationarily on the machine mount, so that the energy storage device or manual machine tool accommodated in the machine mount is held in a stable relative position to the machine interface. As a result, for example, electrical contacts of the machine interface and the hand-held power tool or the energy storage device can be held in position relative to one another. Even with a wireless transmission of data and / or energy between on the one hand the machine interface and on the other hand, the hand-held machine tool or the energy storage device, it is advantageous if the machine interface and the hand-held machine tool or energy storage device are in a stable position relative to each other.

In the bus interfaces of the transmission device are wireless or contact variants, even in combination, possible: preferably comprises at least one bus interface provided for the wireless transmission of energy and / or data transmission means, for example a coil assembly or a coil and / or at least one electrical contact, for Example, a connector, an electrical contact surface or the like, for establishing an electrical connection to the bus interface of the stacked or the stacked stacking element. The bus interface may also be formed by the wireless transmission means or the at least one electrical contact or an electrical contact arrangement. In this case, it is possible for the bus interface to be designed, for example, to transmit data as a wireless interface or to have correspondingly wirelessly operating transmission means, while at least one electrical contact is provided for transmitting energy.

Preferably, the transmission means of the bus interface comprises at least one coil. A coil is suitable for inductive transmission of data and / or energy. The coil preferably has a flat shape, with a flat side of the coil running transversely to the stacking direction, for example at right angles. Thus, the coil may be relatively flat, for example, on the bottom wall or later still present cover wall of the stacking container or be recorded there.

It is expediently provided that the bus interfaces of the transmission device are aligned with one another in the stacking direction. The arrangement of the transmission device in the container insert or on the container insert is thus made such that the bus interfaces are arranged coaxially, for example, in a longitudinal axis or longitudinal direction parallel to the stacking direction. Thus, for example, connectors of a bus interface of the inventively equipped stacking container with connectors of the stacked or the stacked stacking element can come into direct contact. But even with wireless transmission means, such as inductive transmission means, a bus interface, it is advantageous if they are arranged based on the container insert on the stack container so that they are positioned in alignment with inductive or other wireless transmission means of a stacked or a stacked stacking element. As a result, they are transmission losses of the bus connection as small as possible.

It should also be noted at this point that expediently the bus interfaces are configured identically, i. that, for example, the bus interface of the upper side and the bus interface of the underside of the stacking container are similar, in particular identical in shape.

At least one bus interface is expediently arranged directly on a bottom wall of the underside of the stacking container or a top wall of the stacking container, in particular a top wall of a lid of the stacking container. However, at least one bus interface can also be arranged in a passage opening provided on the bottom wall or top wall of the stacking container. This configuration is in any case present when the container insert is included in the congestion recording.

In the area of the at least one bus interface, the stack container is expediently provided in that the stack container does not rib or otherwise Has projections. Thus, it is advantageous if a wall surface of the stacking container has a flat shape in the region of the at least one bus interface or is designed as a plane surface.

Preferably, the stack container has a passage opening or an opening for at least one bus interface. The passage opening is suitable, for example, for the bus interface of the stack container equipped according to the invention to be able to come into direct contact with a bus interface of the stacked or stacked stack element or, in any case, no wall is arranged between the bus interfaces. But even if no passage opening is present, the aforementioned immediate arrangement of the bus interface on the bottom wall or top wall is advantageous. For example, it is advantageous if a coil or another transmission means of the bus interface is provided flat against a top wall or a bottom wall of the stack container. In particular, this is advantageous if the coil or the other transmission means of the bus interface has a flat shape.

It is preferred if a bus interface is arranged on a cover of the stacking container for closing the accumulation receptacle when the container insert is arranged in the stowage receptacle and the accumulation receptacle is closed by the cover. For example, there is advantageously a coil or other inductive or wireless transmitting transmission means. The bus interface can also be arranged above the congestion receiver or outside the congestion receiver. With the lid open, the bus interface protrudes upwards in front of the congestion receiver.

The container insert is expediently adapted to the positive engagement with the bottom wall and / or fitting against at least one peripheral wall of the plug-in receptacle. On the bottom wall or at least one peripheral wall of the accumulation receiving the container insert is then applied when it is received in the accumulation receptacle.

It is preferred if the container insert is designed as a plug-in component for releasable insertion into the accumulation receptacle. Thus, the container insert can be inserted with the transmission device in the plug-in receptacle and there is already in an optimal position.

In principle, however, it is also possible that the container insert is additionally or alternatively fixed to the positive-fit hold in the congestion receptacle, for example by a screw connection and / or gluing and / or clamping and / or latching.

A further variant of the invention can provide that at least one bus interface is arranged in a foot of the stacking container or communicates with a transmission element, for example a metallic or magnetically conductive transmission element, in a foot of the stacking container when the transmission device is received in the stacking container. The foot protrudes, for example, in front of the outside or an outer wall of the stacking container. A transmission element, for example a plate or the like, may be embedded in the foot. For example, the transmission element may direct a magnetic or electrical flow of the bus interface to or from the stacked or stacked stacking element.

It is preferred if the stacking container or the transfer device or the container insert a wireless or wired feed interface for feeding electrical energy and / or compressed air into the bus connection and / or a particular connector having a communication interface for wireless or wired connection of the bus connection to a communication network, for example, to a LAN (Local Area Network), and / or for communication with an HMI device. Thus, the stack container or the transfer device or the container insert forms, so to speak, an interface for the bus to the outside. By way of example, the feed-in interface may comprise an electrical supply line and / or electrical supply contacts for connection to an electrical energy network, for example with 230 V or 120 V.

However, it is also possible for the transfer device and / or the container insert and / or the stack container to have at least one sensor for detecting an operating status of the hand-held machine tool or of the accessory part thereof. For example, the sensor may serve to detect a number of operating hours and / or a service interval and / or a fault information. A state of charge of an energy store or of the aforementioned energy storage device can also advantageously be detected on the basis of the sensor. Furthermore, it is advantageous if at least one sensor for detecting quantity information about consumable material present in the accumulation receiver forms part of the transfer device, the container insert or the stack container.

Such a sensor comprises, for example, a radio module for wireless communication with a controller or a memory of the hand-held machine tool or of the energy store.

Also advantageous is a locating device as part of the transfer device and / or the container insert and / or the stack container, wherein the locating device is provided for wireless location of the stack container or the hand-held machine tool or its accessory part based on an operating device. Again, it is advantageous that the locating device does not necessarily have to form part of the stacking container, but is provided, for example, on the container insert or the transfer device.

It is preferred if the stacking container has coupling means for the tensile strength connection with the stacking element stacked on the stacking container and / or the stacking element stacked under the stacking container with respect to the stacking direction. Thus, the stacking element and the stacking container can be held together by the coupling means with respect to the stacking direction or along the stacking direction, so to speak. It is preferably provided that the stacking container is designed for tensile connection with a stacked and also a stacked stacking element. The coupling means include, for example Bar elements, tabs or the like other form-fitting connectable to the stacked or stacked stacking elements each elements. Form-fitting contours, which are suitable, for example, hooks, latching noses or the like for tensile bonding with the stacked or stacked stacking element along the stacking direction or with respect to the stacking direction, can form components of the coupling means.

Furthermore, it is advantageous if the stacking container has form-fitting contours for positive engagement with counter-positive contours of the stacked on the stack container or under the stack container stacked element, wherein the stack container is held with respect to the stack element by these form-fitting contours transversely to the stacking direction in a stable relative position. For example, the form-fitting contours and counter-form-fitting contours include form-fitting projections and form-fitting receptacles, e.g. Feet at the bottom of the stacking container and suitable for the feet receptacles on the top of the stacking container, in particular its lid.

A preferred concept provides that the stacking container has no electrically active components with respect to the bus connection to the stacking element stacked on it or stacked under it. Thus, for example, on the stack container itself, for example, the container carcases or lid or both, no electrical contacts, coils or the like necessary. These functions are performed by the transfer device and the container insert on which the transfer device is arranged.

The transfer device is preferably permanently integrated into the container insert. For example, coils or the like other suitable for wireless transmission transmission means are fixedly arranged on a body of the container insert.

But it is also possible that the container insert has a receptacle, in particular a plug-in receptacle or clamping receptacle, for the transmission device. In this case, the transmission device advantageously has a holding device or a holding body, on which the transmission means, in particular wirelessly transmitting transmission means, are arranged. The holding body or the holding device of the transmission device can be inserted, for example, in the receptacle of the container insert.

The stack container and / or the container insert are preferably made of plastic. For example, they are each designed as plastic moldings. For example, the stack container is designed as a hollow molded body or injection molded part. The same applies to the container insert, which can be configured for example as a hollow molded body or molded body.

The stack container designed according to the invention expediently forms part of a stack arrangement which comprises at least one further stacking element stacked in the stacking direction on the stack container or under the stack container, for example a further stack container.

FIG. 7

a schematic view of the stacking arrangement according to the above figures to illustrate an effective inductive transmission concept.

A stack arrangement 10 has a stack base 11 on which stack containers 12, 13 are stacked. As an alternative to the stack base 11, a stack base 111 in the form of a vacuum cleaner 90 can also be used, on which the stack containers 12, 13 can also be stacked in a stacking direction S. In addition, a carrying container 14 can be stacked on each of the stack containers 12, 13 or also on the vacuum cleaner 90 or the stack base 11.

By way of example, the stack base 111 and the stack containers stacked thereon 12, 13 form stacking elements 211, 212 and 213. The carrying container 14 can be stacked onto these stack elements as a further stacking element 214.

The stacking containers 12, 13 as well as the carrying container 14 in plan view have approximately the same circumferential contour and the same dimensions, so that such carrying containers and stacking containers can be stacked on top of each other. In addition, the carrying container 14 or the stacking container 12, 13 in the height of each other tensile strength connected, which will become clear later. In any case, by stacking the carrying containers 12, 13 or other such carrying containers stable, as a whole from above tangible stack arrangements, which are widely used.

Although the stack container 12, 13 have the same bottom surface contour, but are different heights. However, this plays for the linking of the stack container 12, 13 and other, not shown stack container in the stacking direction S. not essential. The stack containers 12, 13 will therefore be explained below using the same reference numerals that stand for the same or similar components of the stack container 12, 13.

The stack containers 12, 13 have a container body 31. The container body 31 forms, for example, a lower part 30.

The container body 31 comprises a bottom wall 32, projecting from the peripheral walls 33. The bottom wall 32 and the peripheral walls 33 bound a storage receptacle 140, 40 of the stack container 12, 13th

The peripheral walls 33 include opposing longer side walls 34, 35, for example, a front wall and a rear wall, which are interconnected by shorter side walls 36. However, this should not be understood that the side walls 36 can not be longer than the side walls 34, 35.

The accumulation receptacle 140 of the stacking container 12 and the stowing receptacle 40 of the stacking container 13 have the same or at least substantially or approximately the same or similar inner peripheral contours or the same or approximately the same bottom cross-section from the side of their opening, but have different heights.

The accumulation receptacle 40, 140 or the container body 31 can be closed by a cover 41. The lid 41 has a top wall 42 and peripheral walls 43. The peripheral walls 43 comprise sidewalls 46 which are suitable for the sidewalls 36 and sidewalls 44, 45 which fit the sidewalls 34, 35. Thus, the cover 41 can thus cover the container body 31 or the stowage receptacle 40 in the manner of a hood. When the lid 41 is closed, the peripheral walls 33, 43 are aligned with each other.

The respective lid 41 provides an upper side 18 of a stacking container 12, 13, onto which another similar stacking container, for example one of the stacking containers, is provided 12, 13, but also the carrying container 14, with its bottom 17 can be stacked.

The carrying container 14 also forms a stacking container which can be stacked up on the stack containers 12, 13. A container body 81 of the carrying container 14 has a storage receptacle 80, for example, for transporting tools, in particular manually operated hand tools (screwdrivers or the like). A bottom wall 82 of the container body 81 has the same cross-section as the bottom wall 32 of a stacking container 12 or 13. Thus, the carrying container 14 matches the same shape on the stack containers 12, 13th

From the bottom wall 82 of the container body 81 are peripheral walls 83 which comprise a front and a rear side wall 84, 85 and between these side walls extending side walls 86. A length of the side walls 84, 85, 86 corresponds to that of the side walls 34, 35, 36.

In the storage container 80, an upwardly projecting carrying handle or handle 87 is provided at the carrying container 14, which can be grasped in the manner of a handle. Below the handle 87, a receptacle 88 is provided in the container body 81, into which a handle 87 of one of the under-stacked similar carrying container 14 fits in particular form-fitting manner.

The stack containers 12, 13 and the carrying container 14 can be stacked on the vacuum cleaner 90, which also forms a system component in this respect. The vacuum cleaner 90 has a housing 91 which is expediently movable on rollers 92 on a substrate. The housing 91 is covered by a lid 93. On a front side of the housing 91 is a suction inlet 94, can be sucked through the dirt, dust or the like in a dust collecting space or dust collection container, for example, a dust filter bag, not specified. For this purpose, a schematically illustrated suction unit 95 is provided. The suction unit 95 can be supplied, for example via a power cable, a battery, an electric accumulator or other supply device 98 with electrical energy

At the top of the vacuum cleaner 90, preferably on the lid 93, a container receptacle 96 for one of the stack container 12, 13 or the carrying container 14 is provided. By way of example, the container receptacle 96 is a plug-in receptacle 97, so that the respective container 12-14 can be stacked on the housing 91 from above or inserted into it, so to speak.

The stacking containers 12, 13 and the carrying container 14 have at their bottom walls on the outside, ie opposite to the accumulation receptacle 80 or stowage receptacle 40, feet 37, 38, with which they can be parked on a substrate. The feet 37, 38 form, in cooperation with receptacles 47, 48, in which the feet 37, 38 fit fit form fit contours 59 which intermesh form-fitting transversely to the stacking direction S, in this way the stack container 12, 13 or the transport container 14 across the Stacking direction S to keep in a stable relative position. Thus, therefore, the stack consisting of, for example, the stack elements or stack containers 12, 13 can no longer slip or displace transversely to the stacking direction S and remain in a stable alignment along the stacking direction S.

The receptacle 48 for the feet 38 also receives a handle 15 which is adjustable by means of a pivot bearing 16 in a projecting in front of the lid 41 carrying position in which it can be used in the manner of a handle, or in a rest position in the he so far immersed in the receptacle 48 so that he does not project in front of the top wall 42 in the direction of stacking each transport container or stacking container, the stacks so does not hinder.

The already explained plug-in receptacle 97 of the vacuum cleaner 90 preferably forms such form-fitting contours 59, because it fixes the stack container 12, 13 or the carrying container 14 transversely to the stacking direction S form fit.

A further form-fitting contour 59, which acts in a form-fitting fixing manner transversely to the stacking direction S, is formed by a plug-in receptacle 21 of the stack base 11. The plug-in receptacle 21 serves for the positive reception of a respective stacking container 12, 13 or the carrying container 14, wherein the respective container is fixed transversely to the stacking direction S form fit. The plug-in receptacle 21 is bounded on the bottom side by a bottom wall 22 of the stack base 11, laterally by peripheral walls 23. The peripheral walls 23 comprise a front and a rear side wall 24, 25, between which side walls 26 extend. An inner peripheral contour of the plug-in receptacle 21 corresponds to the outer peripheral contour of the lower part 30 or of the container body 31 or of the container body 81 of the carrying container 14.

Furthermore, the stacking arrangement 10 can be coupled tensile strength along the stacking direction S, namely by means of coupling means 50. The coupling means 50 comprise, for example, rear grip contours 39 protruding in front of the feet 38, which are provided for engaging behind gripping contours 49 in the area of the receptacles 48. For example, the Hintergreifkonturen 39, 49 hook contours. The Hintergreifkonturen 39, 49 can be brought into engagement with each other, for example, in a kind of pan-sliding movement H. For this purpose, for example, a respective upper stack container 12, 13 or the carrying container 14 is moved approximately transversely to the stacking direction S relative to the lower stacking container 12, 13 and then pivoted in a pivot axis E, namely, when the hook contours or hook surfaces of the Hintergreifkonturen 39, 49 face each other have come until the bottom walls 32, 82 rest on the top wall 42.

This hook connection or rear-engagement connection of stacking containers or transport containers is additionally secured by a lock on the front side of the stack arrangement 10. This lock also acts tensile strength in the direction of stacking direction S. For example, locking elements 51 of the coupling means 50 are provided on the covers 41, which are pivotable about pivot bearing 52. The locking elements 51 have receptacles 55 which are pivotable past abutment contours 53, 54, until the locking elements 51 are in engagement with the abutment contours 53, 54.

The abutment contours 53, 54 and the locking elements 51 are provided on the front sides of the Behälterkorpusse 31 and the lid 41. The abutment contours 53, 54 protrude, for example, in front of the front side walls 34, 44. The abutment contours 53 are provided, for example, on the lids 41, the abutment contours 54 on the container bodies 31. For example, an abutment contour 54 is provided near the bottom wall 32 and an abutment contour 54 near the lid 41. The locking element 51 can, as in FIG. 1 shown below, the stack container 12, 13 tensile bond with each other, wherein the between the Behälterkorpusse 31 of the stack container 12, 13 interposed or stacked lid 41 remains without tensile load. For example, the locking element 51 on the one hand with the on the front wall or side wall 34 upper abutment contour 54 or the abutment contour 54 of the stacked stacking container 12 and on the other hand with the abutment contour 54 of the stacked stacking container 13 at the same time engaged and connects this tensile strength.

It is also possible that a locking element 51 serves only as a closure for the lid, wherein it as in the stack container 13 according to FIG. 1 For example, only with the abutment contour 54 of the cover 41 associated container body 31 of the stacking container 13 is engaged. Optionally, the locking element 51 is also still with one or more abutment contours 53 of the lid 41 of the upper stacking container 13 into engagement to hold the lid 41 fixed to the container body 31 or the lower part 30 of the stacking container 13.

However, the coupling means 50 may also include, for example, laterally to the stack container 12, 13 and / or the transport container 40 arranged abutment contours 56 and frontally provided on these containers abutment contours 57 include. The abutment contours 56, 57 are designed, for example, in the manner of latching projections which can engage with lugs 58, 158, 258. In FIG. 1 the tabs 58 are shown only schematically. They are for example pivotally mounted on a respective container base 31 and can preferably the respective lid 41 bridging in engagement with the abutment contours 56, 57 of the lower part 30 or container body 31 of each upper stack container 12, 13 or the carrying container 14 are brought, where they then also zugfest act with respect to the stacking direction S coupling.

When transport container 14 are abutment contours 256, for example, locking lugs similar to the abutment contours 56, approximately in alignment with the handles 87 on the respective container body 81 is provided. On the container body 81 are also still brackets 256. The abutment contours 256 are provided near the bottom wall 82, the tabs 258 close to the handle 87. When similar transport containers 14 are stacked on each other, in particular a handle 87 engages the receptacle 88 of a stacked carrying container 14, the tabs 256 of the lower carrying container 14 can be brought into engagement with the abutment contours or locking lugs 256 of the upper carrying container 14. As a result, a tensile coupling with respect to the stacking direction S is also feasible.

Between the vacuum cleaner S, which can also serve as a stack base, and a transport container 12, 13 or a carrying container 14 also coupling means 50 are provided. For example, 97 tabs 158 are provided close to the plug-in receptacle, which are brought into engagement with the abutment contours 56, 57. For example, the tabs 158 or retaining projections 158 are pivotable or mounted transversely to the stacking direction S displaceable on the lid 93 and the housing 91 of the vacuum cleaner 90.

In relation to the stacking direction S tensile coupling means 50 are further between the stack base 11 and a respective stack container 12, 13 or optionally also the carrying container 14 is present. For example, on the side wall 25, a Hintergreifaufnahme or Hintergreif contour 29 is provided, in which the Hintergreifkonturen 39 of the feet 38 can engage, similar to the Hintergreifaufnahmen or Hintergreifkonturen 49th

In addition, a respective stacking container 12, 13 or carrying container 14 with respect to the stacking direction S can be secured to the stacking base 11 by means of a lock 27. The lock 27 has, for example, a retaining projection not visible in the drawing, which can be brought into engagement with the abutment contours 57 when a stacking container 12, 13 or carrying container 14 is received in the plug-in receptacle 21.

The stacking containers 12, 13 are suitable for transporting hand-held machine tools, for example, grinding machines, saws, cutting devices, drills or screwdrivers. In the stack container 13, for example, a hand-held power tool 500 is received in the form of a drill or a screwdriver. The hand-held power tool 500 has a housing 501 in which a drive motor 502, optionally a transmission and the like, other typical components for hand tools are added. The drive motor 502 drives a tool holder 503, to which a tool, for example a screwing tool can be arranged. The handheld power tool 500 can be conveniently gripped on a handle 504. The handheld power tool 500 has an energy storage device 510 for wireless operation, which includes, for example, electrical storage cells 511. A housing 512 of the energy storage device 510 can be detachably fastened, for example, to the handle 504.

In principle, it is possible that in a stacking container 12, 13, a hand-held machine tool, for example, the hand, machine tool 500 can be freely stored. The congestion recording 40, 140 is correspondingly large. However, it is advantageous if the respective hand-held machine tool is held in a form-fitting manner, that is, at least transversely to the stacking direction S, a certain hold is found. By way of example, this is illustrated by the hand-held power tool 500 designed, for example, as a screwdriver.

For at least partially positive holding a respective hand-held machine tool and / or an energy storage device container inserts 60, 160 are provided in the stacking containers 12, 13. A respective container insert 60, 160 has, for example, an insert body 61 which has a transport receptacle 62 for transporting a hand-held machine tool, for example the hand-held machine tool 500, and / or an energy storage device, for example the energy storage device 510.

The transport receptacle 62 comprises, for example, a machine receptacle 63, in which the hand-held power tool 500 is at least partially or in regions The transport receptacle 62 may also include an energy storage receptacle 163, so to speak, a further machine receptacle, which is designed to hold the energy storage device 510. For example, an energy storage receptacle 163 for the energy storage 163 is present.

The container inserts 60, 160 are not freely movable in the jam seats 40, 140, but held stationary. For this purpose, for example, a screw 264 may be provided. For example, one or more screws penetrate the bottom wall 32 of the stack container 12 and penetrate into a bottom side of the container insert 160.

Alternatively or in addition to such a hold by means of, for example, a screw connection, clamping connection or latching connection, however, it is advantageous for the container inserts 60, 160 to be received in a form-fitting manner in the stowage receivers 40, 140. For example, they have front and rear side surfaces 64, 65 which bear against the inside of the side walls 24, 25 facing the accumulation receptacle 40, 140 at least in sections. Furthermore, the container inserts 60, 160 preferably side surfaces 66 which are provided for at least partially positive or surface contact with the congestion receiving 40, 140 facing inner sides of the side walls 36. Thus, therefore, the container inserts 60, 160 and their Einsatzkorpusse 61 are fixed transversely to the stacking direction S in the jam receivers 40, 140.

The container inserts 60, 160 can be inserted from the upper sides 18 of the container body 31 into the stowed receptacles 40, 41 configured as plug-in receptacles along a plug-in axis which corresponds to the stacking direction S and are held there. A fixation along the plug-in axis, that is to say in the present case the stacking direction S, can be achieved, for example, by means of an additional latching 265, adhesive bonding or the screw connection 264. The latching 265 comprises, for example, a latching receptacle on the container insert 160 into which a latching projection which projects in front of the bottom wall 22 of the stacking container 12 in the direction of the accumulation receptacle 140 engages. A deadlock will be for example realized in that the side surfaces 64, 65, 66 abut in the press fit on the inner sides of the accumulation receiving means 40, 140.

However, the container inserts 60, 160 are beyond their function as holding devices for hand tool machines, energy storage devices or other consumables, such as abrasives, grinding plates, screws, tools, such as screwdriver bits, saw blades or the like, electrically active components. They form transmission modules 75, 175 with which a bus connection B between the stack elements 211-214 can be realized.

Namely, the container inserts 60, 160 comprise, detachably or integrally, a transmission device 70 comprising transmission means 76 for wireless transmission of data and / or energy between the stacking elements 211-214. The transmission means 76 include, for example, coils 176, which are provided for electrical energy transmission. The stack bases 11, 111 have transmission means 76 suitable for the transmission means 76 or suitable for communication with the transmission means 76, for example likewise coils 176, so that the stack bases 11, 111 together with the stack elements 212, 213 can realize the bus connection B.

The transmission means 76 form bus interfaces 77, 78, which are arranged on the respective upper sides 18 and lower sides 17 of the stack containers 12, 13. The transmission means 76 arranged on the upper sides or the sides of the stack bases 11, 13 facing the stacking containers 12, 13 form, for example, bus interfaces 178, in particular bus couplers. The bus interfaces 178, 78 are designed for communication with the bus interfaces 77, for example for wireless, for example capacitive and / or inductive, transmission of data and / or energy.

Alternatively and / or additionally, however, contact-based data transmission and / or energy transmission can also be part of the bus connection B or can be realized in the context of the bus connection B. For this purpose, for example, electrical contacts 79 on the lower sides 17 and the upper sides 18 of the stack container 12, 13 provided. Matching electrical contacts 179 are preferably provided on the stack bases 11, 111. The contacts 79, 179 include, for example, plug-in projections and plug-in receptacles, fixed contact surfaces and contact surfaces that are spring-biased in the direction of the fixed contact surfaces or the like. In any case, the electrical contacts 79, 179 are positioned on the stacking members 211-213 so that they can contact each other in the stacked state of the stacking members 211-213. The electrical contacts 79, 179 are aligned, for example, with axes parallel to the stacking direction S.

The coils 176 have a flat shape and are arranged directly on the upper sides 18 and the lower sides 17 of the stack containers 12, 13 and on the upper side on the stack bases 11, 111.

The coils 176 are preferably flat on the closed and uninterrupted walls, the respective bottom wall 32 and the respective top wall 42 at.

But it is also possible that for ease of transmission or better transmission of an electric or magnetic field for wireless data transmission or energy transfer or both breakthroughs 42A provided on the top wall 42 and corresponding openings (not shown) on the bottom wall 32 at those locations, where the coils 176 are provided.

In particular, expediently corresponding openings for the electrical contacts 79 are provided on the bottom wall 32 or the top wall 42. Namely, the contacts 79 are present directly on the container insert 60 or 160 and not on the stack container 12 or 13.

The contacts 79 are conveniently interconnected by electrical leads 79A. But even between the contacts 79 can within a stacking container 12, 13 or a container insert 60, 160 wirelessly working Communication means, such as inductive or capacitive operating communication means or means for wireless energy transmission may be provided.

The transmission means 76 for the wireless transmission of data and / or energy of a container insert 60, 160 or of the respective transmission device 70 of a stacking container 12, 13 can be interconnected by electrical lines of a line arrangement 76A. But it is also possible that the wireless transmission means 76 within a container insert 60, 160 and a stack member 12, 13 wirelessly communicate with each other and / or configured for wireless energy transmission.

By way of an electrical supply line 301, for example, a power supply unit 302 of the stack base 11 can be supplied with electric current.

Also, the vacuum cleaner 90 can be connected via its supply device 98 as explained to an electrical power grid. For example, the supply device 98, in addition to the suction unit 95, also supplies a power supply unit 302, which can provide electrical energy for the bus connection B, which originates from the vacuum cleaner 90 or the stacking base 111.

The power supply units 302 provide a supply voltage or electrical energy for the bus connection B, which can be transmitted via the bus connection B to the container inserts 60, 160 and thus also to machine interfaces 71, 171, 271, 371. The energy transfer on the bus link B is preferably inductive between the stacking elements 211-213. However, it is also possible to transmit the electrical energy for the manual power tool 500 and / or for the energy storage device 505 via the contacts 79, 179 between the stack elements 211-213. The contacts 79 of a stacking container, for example the stacking container 13, comprise contacts for contacting a stacking element stacked on the stacking container 13 and a stacking element under the stacking container 13, for example the stacking base 11 and are preferably connected to one another via a line arrangement 79A.

The machine interfaces 71, 171, 271, 371 are supplied with electrical energy via the bus connection B.

The machine interface 71 comprises, for example, a transmission means 72, in particular a coil 172, with which wireless electrical energy can be transmitted to the manual power tool 500. This has, for example, a transmission means 505, in particular likewise a coil 506. For example, the coil 506 or the transmission means 505 is arranged on a rear side of the housing 501.

A wireless transmission with likewise a transmission means 72 is provided for example at the machine interface 171 directly to the energy storage device 510. This, too, has a transmission means 505, in particular a coil 506, in order to obtain electrical energy from the coil 172 of the transmission means 72 in an inductive or magnetic manner.

A so-called contact-type variant is realized in the machine interface 271. To the machine interface 271, for example, the energy storage device 510 with its contacts, which are provided per se for establishing an electrical connection to the manual power tool 500, are connected directly. These contacts then enter into electrical connection with electrical contacts 73 provided on or in a receiving recess 269 of the machine interface 271.

The machine interfaces 71, 171, 271 are disposed directly on the receiving recesses 69 or 269 or 369. Thus, the transmission means 72 or the electrical contacts 73 are optimally positioned with respect to the respective energy storage device 510 or manual power tool 500 to be supplied. With the electrical contacts 73, the advantage of this configuration is obvious. But even with the inductive, capacitive or other wireless transmission between the transmission means 72 and 505 is an optimal positioning to avoid transmission losses appropriate. The receptacle depression 369 provided on the container insert 160 forms or comprises, for example a charging tray for charging an energy storage device, in particular in the manner of the energy storage device 510.

The bus interfaces 77, 78 are held in position by the container inserts 60, 160 in relation to the stowing receivers 40, 140 such that they are arranged on the underside 17 and the top 18 when the container insert 60, 160 is received in the stowage receiver 40, 140. For example, the coils 176 of the bus interfaces 77, 78 are held on a holding device 74. The holding device 74, as it were the carrier for the bus interfaces 77, 78 is cylindrical, for example.

The holding device 74 preferably forms an integral part of a container insert 60, 160. For example, the components of the holding device 74 integral with the Einsatzkorpus 61. It is also possible that the holding device 74, for example, in a receptacle 74A of the container insert 160 is inserted ( FIG. 4 ).

The coils 176 are arranged, for example, on the respective end sides or upper sides and lower sides of the holding device 74. The lower end face of the holding device 74, on which the bus interface 77 is held, is directly opposite the bottom wall 32, for example, when the container insert 60, 160 is arranged in the accumulation receptacle 40, 140. On the flat lower end face of the holding device 74, the coil 176 is arranged so that it rests with, for example, on the bottom wall 32 or at most a small distance from the same. It is also possible that the coil 176 penetrates into the unspecified, optional passage opening of the bottom wall 32.

The holding device 74 protrudes toward the upper side 18 in front of the accumulation receptacle 40, 140, so that the coil 176 arranged on the upper end face of the holding device 74 is arranged directly on the cover wall 42, for example in the recess or opening 42A. It can also be provided that the coil 176 is covered by the top wall 42, but they are in the closed state of the lid 41, that is, when he the storage receptacle 40, Covers 140, expediently placed at best with a small distance to the top wall 42 or rests against the top wall 42.

It is also possible that a container insert equipped according to the invention has a communication interface and / or a feed interface directly. For example, the transmission device 70 of the container insert 60 may have a feed interface 201, in particular a power cable for connection to an electrical energy supply network, for example with 120 V or 230 V AC. The feed-in interface 201 leads to a power supply unit 202 that, for example, adapts the voltage of the power supply network to a voltage level which is suitable for the bus connection B and / or the machine interfaces 71, 171, 271.

Furthermore, a communication interface can also be on board a container insert or form part of a transmission device. For example, a communication interface 260 is provided at the container insert 60. The communication interface 260 includes, for example, a Bluetooth interface, a WLAN interface or the like other wirelessly communicating interface.

Alternatively or additionally, a communication interface 360 is provided, for example, on board a respective stacking base 11 or 111. The communication interface 360 also includes, for example, a Bluetooth interface, WLAN interface or the like. But even a wired interface, such as an Ethernet interface, is easily possible.

The communication interfaces 260, 360 are designed for communication with operating devices 400 and / or 450.

The operating devices 400 or 450 are, for example, computers, smartphones or the like other mobile operating devices. The operating devices 400, 450 have, for example, a processor 401 and a memory 402 in which the program code of an operating program 403, 453 is stored. The program code came to be executed by the processor 401. The HMIs 400, 450 have For example, an input interface 405, 455, for example, a keyboard and an output interface 404, 454, for example, a display. The display can display and / or modify operating parameters, quantities and other information of the stacking elements 211, 212 or the handheld power tool, accessories or energy storage devices accommodated therein. For example, symbols 460 can be displayed on the output interfaces 404, 454 for the handheld machine tool 500 or another handheld machine tool respectively received in a stacking container 12, 13.

The operating devices 400, 450 include communication interfaces 456, which are compatible with the communication interface 260, 360, that is configured, for example, to a communication via Bluetooth, WLAN or the like.

The communication interface 260, 360 is advantageously connected to the bus connection B. Thus, a respective operating device 400 and / or 450, for example via the communication interface 260, 360 with the hand-held power tool 500, but also, for example, with a recorded in the storage receptacle 140 of the stacking container 12 hand-tool machine, in particular an energy storage device communicate. In this way, for example, a state of charge of an energy store, for example the energy storage device 510, can be queried via the bus connection B and the communication interface 260 and / or 360 via the operating device 400, 450.

Furthermore, it is possible for the transfer devices of a container insert or stack container equipped according to the invention to include a locating device 261, for example to determine in this way whether a hand-held machine tool, in particular also which type of hand-held machine tool, has been received in a respective stacking container.

Furthermore, for example, a sensor 262 may be a component of the transmission device 70, with which an operating status, for example the number of operating hours, a manual power tool 500 or the energy storage device 510 can be determined. The sensor 262 may autonomously communicate by wireless or the like with another example wirelessly one of the HMI device 400 or 450. However, it is also possible that the sensor 262 is connected to the bus connection B, in particular the line arrangement 79A.

In a respective congestion receptacle 40, in particular a transport receptacle 62, but also consumables, for example, abrasive material or the like, can be recorded. A sensor 263, which preferably forms part of the transmission device 70, can detect the status of the consumables, for example their quantity and / or quality. The sensor 263 may also communicate wirelessly with the HMIs 450 or 400 wirelessly. However, it is preferred if the sensor 263 is also coupled to the bus connection B, for example connected to the line arrangement 79A.

The sensors 262, 263 connected to the bus connection B or coupled into the bus connection B can communicate with the operator devices 400, 450 via the communication interface 260, for example. Thus, for example, with one of the operating device 400 or 450, a respective sensor 262, 263 are queried.

The locating device 261 may also have a self-sufficient wireless interface, for example a Bluetooth interface, with which the operating devices 400 or 450 can communicate directly. However, it is advantageous if the locating device 261 is coupled into the bus connection B, for example connected to the line arrangement 79A.

Conveniently, the carrying container 14 in the bus B can be coupled. For example, the carrying container 14 has a bus interface 77, which can communicate with the bus interface 78 of the stacking container 12, 13. By means of the bus interface 77, for example, a device stored in the carrying container 14, in particular a hand-held machine tool, can be connected to the bus connection B and thus operated, for example, using the operating device 400 or 450, in particular for retrieving data.

However, a stack container can also contribute at least passively to optimized data transmission or energy transmission between stack containers, for example by means of an inductively conductive transmission element 272 which is arranged in one of the feet 37 or 38. This may, for example, amplify or relay the magnetic flux of a coil or other transmission means 272 of a bus interface 277 suitable for establishing a bus connection to a stacked or stacked stacking container or stacking element, e.g. only an upper bus interface 278 is indicated.

A stacking base, for example the stacking base 111, can also form or have an operating device. For example, the vacuum cleaner 90 has an output interface 354. A controller of the vacuum cleaner 90, which includes, for example, a microprocessor and the like other components, or a separate microprocessor 401 provided for executing the operation program 353 explained below may be configured, for example, program code of an operating program Execute 353, which can communicate in particular on the basis of the communication interface 360 via the bus B to the stack containers 12, 13 and in particular the hand-held machine tools or energy storage devices housed therein, for example, to display their operating data.

At the in FIG. 7 illustrated schematic embodiment of the invention, the stack container 12, 13 with respect to the electrical transmission of energy on the bus connection B so to speak passive. The stacking base 11 has, for example, a power supply unit 702, which can be connected via a connecting cable 701 to an electrical energy supply network with, for example, 120 V or 230 V alternating current. The power supply unit 702 has, for example, a power generating device 767 for providing an alternating current Iw for an electrical coil or a coil arrangement 776 of the bus interface 178. Alternatively, it is also possible for the power generating device 767 to be supplied with energy on the input side, for example by an accumulator or another mobile energy storage device 703.

It is preferred if the coil or coil arrangement 776 is connected in series with a capacitor 775.

The current generator 776 is designed to generate an alternating current Iw with a fixed frequency or current or voltage, but preferably with variable frequency and / or variable current intensity and / or variable voltage for the coil arrangement 776.

The transmission devices 70 of the stack containers 12, 13 have the already explained coils 176 at their bus interfaces 77, 78. These coils 176 are interconnected by the conduit assembly 79A. It is preferably provided that the coils 176 of a respective transmission device 70 are connected in parallel. Furthermore, it is expedient if in each case a capacitor 675 is connected in parallel to the coils 176, so that the coils 176 together with the capacitor 675 form a resonant circuit.

The power generating device 776 preferably provides the alternating current Iw in the resonant frequency of the coils 176 in combination with the capacitor 675 of a respective transmission device 70. Thus, an optimal magnetic coupling between the stack base 11 and the stack containers 12, 13 and the stack elements 212-213 with each other is possible.

A power conditioning device 676 is connected to the capacitors 675. For example, it prepares input voltage Ue provided by capacitor 675, which suitably corresponds to the voltage between the lines of line array 79A, and provides output voltage Ua, for example, to machine interface 71 and / or a communication interface 660. The output voltage Ua is significantly smaller than the input voltage Ue, for example, only half as large.

Via the communication interface 660, the transmission devices 70 of the stack containers 12, 13 can in particular communicate wirelessly with a communication interface 760 of the stack base 11. In this way, the Transmission devices 70, for example, identify identifiers of each arranged in the congestion recording hand-held machine tool, current charging voltages or charging currents or the like. For example, it is thus possible that the communication interface 760 informs the power generation device 767 of the current state of charge of handheld power tools or energy storage devices accommodated in the stacking containers and / or power consumption of the respective machine interface. The power generating device 767 can adjust in this way, for example, the current level of the alternating current Iw and / or its frequency and / or its voltage to provide an optimal power supply of the stack container 12, 13.

A frequency adjustment serves, for example, to adapt the energy consumed or required in the stacking arrangement 10.

The communication interface 660 can also be configured to switch off the spool which is not required, for example in the topmost stack container or stack element of a stack arrangement, for example by means of a switch 678 in the stack container 13.
