Description

The The invention relates to an output tray for or in a vending machine. The invention further relates to such a vending machine.

Vending Machines, in the relevant literature often also as a self-seller can be designated formed in a variety of different configurations be, for example, as cigarette vending machines, vending machines and the same. Although in principle on any vending machines Applicable, the present invention as well as its basis lying problem below with respect to vending machines for dispensing bottles explained.

vending machines have in the interior goods receiving devices for receiving the goods on. These goods receiving devices are depending on how the individual Goods are stored inside the vending machine, designed differently. While earlier the various goods usually bay, arranged one above the other in the interior were and from the outside due to a mostly opaque front door were not visible, should the goods in modern vending machines from the outside to be clearly visible. modern Vending machines have a large area Glass front doors up, over the one potential buyer presents the goods product shall be.

at such modern vending machines, the goods are usually in the front window aligned goods compartments stocked, with the goods compartments are typically arranged side by side and / or one above the other. Those standing in the goods subjects or hanging Goods are thus about the transparent windscreen for a potential buyer visible, which proved advantageous for technical reasons has, as the supposed buyer directly, so without obstructions, can recognize which product he actually buys.

While at previous vending machines one from such a vending machine removed goods in a for all goods compartments provided goods output tray has fallen down and taken from there could be avoided in modern vending machines. In particular, in the case of the upper goods compartments of a vending machine falls one Ware comparatively very deep in the typically close to the ground arranged Goods output tray. With the falling out of the goods from high altitude goes sometimes a damage This product is associated, especially in commodity products with a thin, little stable or fragile housing or with a flexible packaging.

Around to avoid this modern vending machines over a specially for the removal of a requested goods product provided withdrawal device, along the front of the various goods compartments in X / Y direction is freely movable and thus in the case of a goods request a respective department, which contains the requested goods targeted can start. The requested product is now from this sampling facility taken directly, with the requested goods only from one low altitude first into the subject of the removal facility and no longer to a certain extent over the entire height of the vending machine. This removal device conveys the so received after completion of the withdrawal process to a especially for it provided goods outlet of the vending machine, which typically arranged at waist height is, so the buyer the requested goods conveniently, without having to bend over, can remove. A damage The goods are usually omitted here.

at Such a known vending machine is the goods issue usually accessible from the outside, the requested and paid for goods from the vending machine to be able to remove. These accessibility of the goods issue compartment is a mandatory one in the case of a goods request Part of the removal process of a product from the vending machine.

However, the following problem arises with a goods issue compartment accessible from the outside:
Although the goods issue tray is typically closed again from the inside, for example, by a panel after goods have been issued. This panel is open when, for example, the product is removed from a removal device movable in the XY direction from this removal compartment and is transported via the opened panel into the goods issue compartment. Subsequently, the panel is closed again, so that the interior of the vending machine is not accessible from the outside. However, such a construction is sometimes susceptible to misuse, for example, if this panel inside the housing of the vending machine, when it is just opened in the case of a goods issue, is blocked by an abuser, since thereby the interior of the vending machine via the goods output tray from the outside accessible, which should be avoided, however. The abuser can then remove the arranged in the interior of the vending machine in appropriate goods compartments or other recording devices goods with more or less effort. This is to be avoided under all circumstances.

Another aspect is that Ver often located in public freely accessible. In the process, externally accessible goods outlets of the vending machines are sometimes used abusively as rubbish bins in which packaging and similar waste are deposited. As a result, these goods output compartments are very often no longer empty, which on the one hand makes the vending machine look unsightly and on the other sometimes makes it difficult to dispense goods and in extreme cases, if the entire goods output tray is filled with trash, impossible. In addition, the issued goods, which is requested by a buyer, is polluted by the garbage, which then discourages a buyer very often from a purchase. The risk of "Vermüllens" the goods issue compartment of a vending machine can be at least partially eliminated, for example, by a hinged flap or sliding panel attached from the outside to the goods output tray. However, such a hinged flap or a sliding from the buyer aperture makes the removal process of the product, since he can no longer easily remove the goods with one hand.

In front In this background, the present invention has the object to provide a device that allows easy removal a requested product from a vending machine, through the same as the security requirements of the vending machine unimpaired stay.

According to the invention this Task by a goods issue compartment with the features of the patent claim 1 and / or by a vending machine with the features of the claim 20 solved.

• – mit einem Gehäuse, welches eine erste nach außen hin gewandte Warenöffnung und eine zweite zu einem Innenraum des Verkaufsautomaten gewandte Warenöffnung aufweist, und
• – mit einer innerhalb des Gehäuses vorgesehenen Warenschleuse zur Aufnahme und zum Weitertransport einer aus dem Verkaufsautomat angeforderten Ware, die eine dritte Warenöffnung aufweist.

Accordingly, it is provided:
Goods issue device for or in a vending machine,

• - With a housing which has a first outwardly facing goods opening and a second facing to an interior of the vending machine goods opening, and
• - With a goods lock provided within the housing for receiving and for further transport of a requested from the vending machine goods, which has a third goods opening.

• – mit einem Gehäuse, das eine verschließbare Tür zum Befüllen des Verkaufsautomaten aufweist,
• – mit einem Innenraum, und
• – mit einer Einrichtung nach einem der Ansprüche 1 bis 19, mittels der eine angeforderte Ware aus dem Innenraum in eine von außen zugängliche Warenausgabe beförderbar ist.

Vending Machine,

• With a housing having a closable door for filling the vending machine,
• - with an interior, and
• - With a device according to one of claims 1 to 19, by means of which a requested goods from the interior in an externally accessible goods issue is conveyed.

The The idea underlying the present invention is that an output device of a vending machine with a lock function equip.

The has output device according to the invention thus a goods issue tray, in which a rotatably arranged Warehouse is housed. This rotary goods lock contains an opening to the Carry out the respective goods in the goods issue.

in the If goods are removed, the goods lock is opened with its opening a corresponding opening of the housing brought to the interior of the vending machine. About a withdrawal device can such a delivery of goods into the goods lock. After delivery of goods turns the goods lock with its opening towards the opening of the Goods outlets, so that the buyer who requested this goods and has paid, this can also refer to the goods. Subsequently, will The goods lock has been turned so that the goods outfeed compartment is inaccessible from the outside. In the state of goods delivery a commodity from the interior of the vending machine in the goods lock is the goods outbox from the outside also inaccessible.

Consequently the goods output tray is only accessible from the outside when a product is delivered to the outside becomes. The invention is thus characterized by a misuse protected, very safe operation, which nonetheless offers a high level of comfort for the buyer, because the risk of "Vermüllens" the goods issue compartment virtually avoided and thus prevents being requested by a buyer Dirty goods through a garbage contained in the respective goods output tray.

In a preferred embodiment, the goods lock on a so-called shutter function (locking function). This shutter function serves the purpose that the goods output tray and thus the goods lock in the third position, in which the goods issue tray should be inaccessible from the outside, can not be opened. This allows a very effective protection against vandalism, which is always an essential criterion for vending machines in public. In particular, it can be effectively prevented here that an abusive user intentionally gets into the inside of the vending machine via the goods issue compartment or even only soiled or littered the item delivery compartment. In another, also particularly advantageous off This shutter function also provides that this prevents an air exchange between the interior of the vending machine, the goods output tray and the outside of the vending machine. In this way, in particular in such vending machines, which have refrigerated goods inside, a loss of cold over the goods output tray can be prevented, which would always lead to a Energiemeehraufwand. However, this energy expenditure is especially important in so-called stand-alone vending machines, which have only a local energy source, to avoid what is achieved with the shutter function.

The Warehouse according to the invention is preferably driven by a specially provided drive. The drive can be used as an electric motor, for example as a stepping motor or DC motor, be formed. By means of this drive the goods lock is in each case in the desired positions, thus in a goods transfer position, in the goods issue position and finally in a safe, from Outside inaccessible Position turned.

The Goods transfer position denotes a position from which a commodity from the interior of the vending machine through corresponding openings in the case handed over to the goods lock becomes. The goods issue position denotes a position at which the goods from a buyer can be removed from the goods lock. At the safe, from Outside inaccessible Position is an opening in the goods lock at least not from the outside and preferably not accessible from the interior of the vending machine.

Preferably the drive is rotatable in both directions.

In a particularly preferred embodiment is a self-locking Drive for driving the goods lock and / or to lock the same provided. A first requirement for security reasons everyone, from the outside accessible goods lock Fulfills must be, is the anti-trap. Such a pinch protection recognizes in the second position when a body part, such as the Hand, enters the space between goods lock and housing of the vending machine. In this case, a closing movement of the goods lock interrupted and thereby prevents this jammed body part get hurt. On the other hand, of course, it must also be prevented that the goods lock, for example, can be misused and goods tray in the third position is accessible from the outside. By means of the self-locking, according to the invention Drive are both functionalities, that is the prevention a misuse on the one hand and the anti-trap on the other hand, guaranteed.

In A particularly preferred embodiment is a recognition device provided, which detects the loading state of an output tray. By means of this recognition device, it is possible to detect whether the Output tray is busy or unoccupied. This recognition device can For example, an ultrasonic transmitter and / or a corresponding Receiving device comprising the means of ultrasonic detection Checked load condition of the goods issue tray and in this way very reliably determines whether a goods or a goods in the goods output tray other object is present. The special advantage of using such, based on ultrasonic detection device is that even then a level can be detected, provided that the goods output tray does not contain actual ground, but For example, only a grid, web or bracket. In a typical embodiment is this ultrasonic detection device acting on the ground Part of the goods issue tray aligned.

In A preferred embodiment are for the ultrasonic detection device Thresholds are used, for example, only after a through close a goods occupied goods issue compartment, if for a given distance over the Bottom of the output tray a corresponding signal is detected, for example, at a distance of 2-5 cm. This way you can be prevented, for example, a small amount of liquid in the area of the bottom of the goods issue compartment or an existing there Packing part accidentally signaled to the vending machine, that the goods issue tray is occupied.

In In a preferred embodiment, this recognition device for the level of the goods issue tray to be used for the goods issue operation to control. Only when, for example, by means of the recognition device is detected that the goods issue tray is filled, a control signal issued through which the goods lock with its opening in Direction of the opening of the goods issue tray rotates so that the buyer receives the requested goods can take. Is omitted such a control signal, for example if no goods in the goods output compartment or the goods lock is included, then the goods lock is not in the issue position turned.

In addition, the detection device can also be used to detect a removal of a product from the goods lock by a buyer. Is such a removal of goods detek been issued, then another control signal is issued by which the goods lock is rotated with its opening in a safe, inaccessible from the outside position. The goods issue compartment or the goods lock is thus closed, whereby a misuse from the outside virtually no longer possible.

For detection the level the goods lock can instead of an ultrasonic detection also simple weight sensor, in particular a switch provided be, for example, in or under the floor of the goods lock is arranged. Again, here would be an adjustable threshold advantageous from above the vending machine on a filled one Closes goods lock and thus on a goods issue process.

According to the invention is for the self-locking Drive a worm gear provided, which with the goods lock for example, via a coupled to the goods sluice strained belt. This self-locking Drive with worm gear and belt already has the above mentioned two functions.

To the an anti-pinch, by means of the belt and thus by Frictional force causes the anti-trap. By means of a specially designed Spring will be the corresponding frictional force and thus the anti-trap set. Depending on how this spring force is dimensioned, can be Thus, the anti-trap dimension accordingly, that is, the set spring force determines from which counterforce the detection device on a clamped object closes and thus a closing process breaks off and thus prevents jamming.

For snapping and closing (Tamper protection) of the goods lock, the belt has one more or less short tooth area in the closed position in specially provided Gear sections engages the goods lock or coupled gear wheels. In This closure position is thus not the goods lock through Frictional force coupled to the belt, but through the gear portion. In this locked closed state of the goods lock or coupled gears let yourself so these no longer from the outside turn, so that a manipulation of the goods lock and thus of the Goods issue compartments not possible is.

Of the Belt has to provide the above two functions thus two different areas on. A first, smooth belt area, at least in the case of a closing operation by friction with the goods lock in connection. in the Trap would be a pinch Therefore, although the belt trying to lock the goods by stiction to move on. However, that would a jammed object, such as a hand, a drag generate, which is at least larger as the stiction, which causes the belt the goods lock Do not take it with you, but go crazy. This drag, by an object for This spin is required, can be in an advantageous manner adjust by a spring with which this belt defines is biased. Dependent from that exerted by the spring Spring force leaves thus a desired Adjust bias of this belt, which selectively dimensioned can be, from which force applied by an object counterforce in the case of Pinching the anti-trap is activated.

Additionally points The belt, however, a short gear section on. This Gear section is in the closed state of the goods lock in engagement with corresponding gears of the goods lock located. Because these gears, which engage the gear portion of the belt, typically with a drive, such as an electric motor, coupled or connected leaves Thus, this gear also by applying greater force, the outside exerted on the goods lock will not turn. This is a high security against manipulation guaranteed without having to forego the anti-trap protection.

In a preferred embodiment is only a single drive for both above functions, that is for the latching and closing function on the one hand and for the anti-trap on the other hand provided. This only drive either drives the belt with the at least two belt sections directly or via Pulleys and coupling devices on.

According to a further preferred embodiment, the belt is formed continuously with an internal toothing and encloses a non-toothed, preferably flat peripheral region of an associated section of the goods lock. As a result, a frictional engagement between the belt and the associated contact surface of the goods lock is ensured. Furthermore, the belt preferably engages with its toothing in a complementary toothing of an associated pulley for a power transmission or a drive of the goods lock. It is obvious to a person skilled in the art that in this case the belt can also be designed to be smooth throughout, ie without toothing, so that a frictional force transmission is likewise ensured. A locking of the goods lock is achieved according to this embodiment in that preferably a gear on the same drive shaft as the pulley is provided and engages the locking in an associated toothed segment, which is coupled to the goods lock. For example, the toothed segment is provided below the housing of the goods lock such that it can be coupled in a predetermined position of the goods lock with the gear of the pulley. Preferably, a translation gear is interposed between the gear of the pulley and the toothed segment of the goods lock. In this way, a twisting of the goods lock by a coupling of the tooth segment of the goods lock with the gear of the pulley and thus the drive shaft of the drive is advantageously prevented in an elimination of the self-locking drive via the gear system, whereby a locking of the goods lock is ensured in a predetermined position.

In In a preferred embodiment, the goods lock is cylindrical. Typically, the goods lock is to accommodate a single Goods product designed and dimensioned.

The Warehouse has continuous side walls and a floor. In these walls is preferably, but not necessarily, provided a single opening, the handing over of the goods from the interior of the vending machine into the goods lock. Preferably, but not necessarily, the upper portion is the Goods lock closed.

Instead of the provision of an opening in the area of the side walls can the goods delivery from Interior of the vending machine in the goods lock also of their Ceiling area, that is from above. In this case would have an opening in the area of the side walls of the Goods lock not be provided.

Preferably, but not necessarily, the goods lock is made of plastic produced. This material is particularly suitable for reasons of high resistance and rust resistance especially good for permanent use and especially for the self-locking drive with anti-trap protection and snap-in protection. Alternative would be also conceivable, its functionality by a metallic part, For example, a sheet metal or steel part to realize, thereby in particular ensures good protection against manipulation and destruction becomes.

advantageous Refinements and developments of the invention will become apparent the further subclaims as well as from the description in conjunction with the figures of Drawing.

In the figures of the drawing are identical or functionally identical elements, Features and signals, unless otherwise stated, provided with the same reference numerals.

The 1 - 4 show in perspective a merchandise dispenser of a vending machine for different states of a goods issue. With reference to this 1 - 4 First, the construction of such a goods issue device will be described before its functions are outlined.

In 1 is with reference numerals 10 the goods issue device called. The goods issue device 10 includes a housing 11 , The housing 11 includes a frontal housing part 12 in which an opening 13 intended for a removal of goods. In the housing front 12 are also several recesses 14 provided, for example, the recesses of a (not shown in the figures) keyboard. In a side case part 15 is another opening 16 intended for a goods issue. That to the lateral housing part 15 the opposite housing part and the rear housing part are typically (but not necessarily) completely closed or at least have no intended for a goods issue or removal opening.

Preferably, the frontal housing part 12 designed as a door, so that with appropriate unlocking of this door 12 from the outside access to the goods issue device, for example, for their cleaning or maintenance, is possible.

1 further shows a removal device designed as a shopping cart 20 , The structure and operation of such a removal device 20 is known per se and should therefore not be explained in detail below. It is only essential that the removal facility 20 an output lock, output flap 21 or the like, from which in the removal compartment 22 the removal device 20 contained goods product over the opening 16 in the goods issue device 10 can get.

This sampling device 20 is, for example, part of a removal device which can be moved in the interior of the vending machine along the front of the goods compartments in the XY direction, via which a specific goods compartment can be approached in order to remove a respective desired product from this compartment. Subsequently, this removal device moves 20 to the goods issue device 10 and transfers this in a removal compartment within the removal facility 20 provided goods product to the goods issue device 10 ,

Within the goods issue facility 10 a goods output tray is provided, which through the lateral housing parts 12 . 15 and typically also through the floor and ceiling side housing parts of the merchandise dispenser 10 is defined. The 2a and 4a show in plan view this, through the housing parts of the housing 11 enclosed goods issue compartment, which here with reference numerals 17 is designated.

In this goods issue 17 is a goods lock according to the invention 30 intended. This goods lock 30 is, as in the plan views of 2a and 4a as well as in the detail view in 2 B is shown, here cylindrical. This goods lock 30 forms, as it were, a shopping cart for receiving one via the removal device 20 From the interior of the vending machine removed goods product. The goods lock 30 is preferably designed to be rotatable in both directions of rotation.

The hollow cylindrical goods lock 30 points in the area of their soil 32 a detection device 33 on. This detection device 33 is designed to detect whether inside 34 the goods lock 30 a commodity product is or is not. The detection device 33 For example, can work on the basis of ultrasound or as a simple weight sensor, eg. B. as a switch, be formed. An optical sensor as a design for the detection device would also be conceivable 33 ,

The goods lock 30 also has a transfer opening 31 in their housing wall. The size and position of this transfer opening 31 in the goods lock 30 is dimensioned such that they on the one hand at least conclusively or in alignment with the opening 13 is formed, provided the goods lock 30 with the transfer opening 31 is rotated in this position, and, as it were, flush with the opening 16 is formed, provided the goods lock 33 with her handover opening 31 is rotated in this second position.

To provide a rotational movement of this goods lock 30 a drive device is provided. These with reference numerals 40 designated drive device is in the lower part of the goods issue device 10 in her case 11 integrated and, as will be explained, with the goods lock 30 force-coupled. The drive device 40 has a motor, for example an electric motor 41 , on. This electric motor 41 For example, it is designed as a DC motor or as a synchronous motor and is preferably able to provide rotations in both directions of rotation.

The drive device 40 also has at least two, typically different from each other gears 42 and at least one gear belt 43 on. This gear belt 43 may preferably be biased by a dedicated locking and tensioning device. The gear belt 43 is typically around an outer surface of the cylindrical goods lock 30 strained and serves the purpose of this goods lock 30 to be able to rotate about its axis and thus bring it into a predetermined position. To drive the gear belt 43 is at least an electric motor 41 provided the different gears 42 the drive device 40 drives. This will be described below with reference to the subfigures 1b and 1c explained.

1b shows in a highly simplified representation of the plan view of such an arrangement for driving the goods lock 30 , The goods lock 30 has a peripheral surface 30a on. In a partial section of this peripheral surface 30a are teeth 30b provided completely around the ge velvet circumference of the goods lock 30 are arranged. 1b also shows sections of a toothed belt 43 , which is also about the goods lock 30 is stretched and thus on the peripheral surface 30a at the goods lock 30 is applied. This timing belt 43 indicates at its lower, the goods lock 30 assigned page 43a also teeth 43b on. These teeth 43b are designed so that these into appropriate teeth 30b the goods lock 30 can intervene. In the present case, the teeth 30b the goods lock 30 and the teeth 43b in that area of the peripheral surface 30a arranged on which the toothed belt 43 at the goods lock 30 is applied.

1b further shows a gear 42a which is in in 1b not shown manner with the electric motor 41 Power is coupled. The electric motor 41 is thus capable of the gear 42a drive. The gear 42a is positioned with its teeth in engagement with the corresponding teeth 43b of the toothed belt 43 stands. Will this gear 43a over the electric motor 41 driven, this way also the timing belt 43 and thus the goods lock 30 to be moved. About the electric motor 41 can the gear 42a be rotated in and counterclockwise, whereby the goods lock can be rotated axially in any direction and positioned as desired.

In an in 1c illustrated alternative embodiment is the belt 43 not with appropriate teeth 43b but has a substantially smooth surface on the side 43a of the belt 43 , the goods lock 30 turned on, on. In the same way are also on the peripheral surface 30a the goods lock 30 no teeth 30b provided so that the peripheral surface 30a is more or less smooth. For this reason is to drive the belt 43a no gear 42a provided, but it is sufficient here in contact with the belt 43 standing rotatable roller 42a whose surface is, for example, correspondingly roughened, grooved or otherwise perforated. It is also important to make sure that the belt 43 is biased so that it is always in close contact with the roller 42a stands, so that by friction a drive of the belt 43 is possible.

Furthermore, a locking device for the goods lock 30 intended. This is in the 1d and 1e shown. For this locking device, the drive device 40 typically, but not necessarily, a second gear 42b on, which is in close proximity to the goods lock 30 is arranged. The goods lock 30 has on its peripheral surface 30a further a tooth portion 30c on. This tooth section 30c is typically at one to the teeth 30b from the example in 1b different location on the peripheral surface 30a arranged. In the 1d is the tooth section 30c not in engagement with the second gear 42b , whereas in the example in 1e the tooth section 30c in engagement with the second gear 42b located. This position takes the tooth section 30c typically in the closed state of the goods issue 17 one.

The second gear 42b is positioned so that it is connected to the tooth portion 30c can be engaged provided the tooth portion 30c and the second gear 42b face. The tooth section 30c is at such a position on the peripheral surface 30a the goods lock 30 provided that it is in the in 1e shown position in which the tooth portion 30c engaged with the second gear 42b stands, in the closed state of the goods issue 17 or the goods lock 30 located. In this position, the electric motor 41 be activated and z. B. a rotation of the second gear 42e block, which also over the tooth section 30c with the second gear 42b coupled goods lock 30 is prevented from further rotation. The goods lock 30 can then no longer through the first gear 42a and the timing belt 43 rotate. In this way, an effective locking of the goods issue compartment 17 and thus the goods lock 30 possible. An unlocking of the goods issue 17 can then be accomplished very easily by using the electric motor 41 the second gear 42b is released again. This second gear 42b can then turn more or less freely again, which again an unobstructed rotational movement of the goods lock 30 over the first gear 42a and the timing belt 43 is possible.

The electric motor 41 is (in the 1d . 1e not shown) with the second gear 42b Power-coupled, so that via the electric motor, the second gear 42b can be moved. This way is about the electric motor 41 and the second gear 42b in a sense a self-locking drive possible, which is particularly relevant when the second gear 42b in engagement with the gear portion 30c stands. In this way, an effective protection against tampering is ensured by the goods lock 30 and thus the goods issue 17 is locked or blocked, thereby an undesirable twisting of the goods lock 30 can be effectively prevented from the closed state.

In 1f schematically illustrates a locking mechanism according to another preferred embodiment of the present invention. According to this embodiment the belt 43 preferably a continuous internal toothing and surrounds the associated portion of the housing of the goods lock 30 in sections, as in 1f seen. The assigned section of the housing of the goods lock 30 is preferably without teeth, ie flat, formed so that between the teeth of the belt 43 and the associated attack surface of the goods lock 30 a frictional connection exists. It is obvious to a person skilled in the art that for achieving a frictional connection the belt can also be designed without a toothing.

The belt 43 furthermore, as in 1f shown in an associated toothing of an associated pulley 42a one. The pulley 42a sits on a drive shaft which is coupled to an associated drive.

On this drive shaft is seated according to the present embodiment further comprises a gear 42c , Further, according to the present embodiment, a tooth portion 30c below the housing of the goods lock 30 provided and with the goods lock 30 connected, the toothed segment 30c , in a predetermined position of the goods lock 30 , namely preferably in the locking position of the goods lock 30 , via a translation gear 42b with the gear 42c can be coupled.

By this arrangement, when driving the drive shaft and thus the pulley 42a the goods lock 30 by means of the belt 43 rotated in a predetermined direction. When the drive is not activated, for example a self-locking drive, the position of the goods lock becomes 30 locked in the position in which the sector gear 30c over the translation gear 42b with the gear 42c and thus the drive shaft or the self-locking drive is coupled. Consequently, a feedback is ensured in an advantageous manner.

In addition, one is also in the 1b and 1c Not shown anti-trap protection provided in the case of the embodiment in the 1c z. B. works by stiction. In case of jamming, they can be put on the goods lock 30 acting forces are so great that these are the stiction of the belt 43 on the peripheral surface 30a exceeds, so the belt 43 no longer the goods lock 30 on the peripheral surface 30a can turn.

Conceivable here would be the monitoring of one of the first gear 42a or the roller 42a applied torque. If this torque exceeds a predetermined threshold, the z. B. when pinching an object or a hand in the goods lock 30 occurs, then it can be provided that a further rotation of this first gear 42a or the corresponding roller 42a is omitted and thus the goods lock 30 not spinning anymore. Preferably, in such a case, the goods lock is slightly rotated back to release the clamped object or a hand again.

The following is based on the 1 - 4 the operation of the merchandise dispensing device according to the invention 10 and in particular its goods lock 30 and drive means 40 explains:

1 shows a first, so-called transfer position. Before this transfer position, the goods lock 30 first by means of the belt 43 turned into this transfer position. Before that was the goods lock 30 in a rest position, wherein the opening in a rear area of the goods output tray 17 was located so that you do not have the opening from the outside 31 into the interior of the goods lock 30 can get.

It would also be conceivable in this context that, for example, a plurality of juxtaposed goods compartments and / or several superimposed goods compartments together form a merchandise compartment module in which the goods compartments contained there are fixedly coupled to each other and thus can always be pushed out together and also back into the interior of the vending machine can be pushed. In this case, according to the invention, it would only have to be determined in one of these goods compartments whether it is located in the first or in the second position.

Instead of a cylindrical Design of the goods lock would of course also here a cuboid, hexagonal, oval or the like designed goods lock conceivable. Also Not a single drive is necessarily required, though this is particularly advantageous. Rather, the above Functionality of Einrastsicherheit and thus the manipulation security on the other and the anti-pinch protection, on the other hand, by two or more Drive devices are provided, although this slight is more complicated.

Also the special construction of a goods issue device 10 is not necessarily to the embodiment in the 1 - 4 limited, but can be, depending on how a vending machine 50 designed to adapt to its construction in a variety of ways.
