The vending machine 1 comprises a housing 3 and a payment terminal 4 on the housing 3, which is primarily meant for making payments but also for displaying the user interface, receiving the data entry of the user (and making the payments): The payment terminal 4 shown in the view on Figure 1 comprises a display, a keyboard, a slot for inserting / removing a bank card and a slot for a receipt output.
As an option, the payment terminal may comprise a cash payment unit, a touch screen (in this case a separate keyboard is not necessary).
The vending machine 1 in the housing 3 comprises also a control means 5, a package gripper 6, which is movable in the longitudinal, crosswise and vertical direction of the housing, a conveyor 7 for moving packages into a package dispensing position, a package dispensing module 8 that comprises a roller track in the embodiment, depicted in the drawings. In the embodiment, depicted if the drawings a belt conveyor is used as a conveyor 7.
In the preferred embodiment, the payment terminal and the control means are integrated into a single unit.
One of the characteristic features of the vending machine 1 according to the present invention is a fact that the housing 3 is adapted for receiving packages stacked on pallets 9.
There are filling doors 10 on the housing 3 for loading the pallets 9. In the embodiment depicted in Figure 3, the filling doors 10 are located in the end wall of the housing 3. In the embodiment depicted in Figure 4, the filling doors 10 are located in one of the longer walls of the housing 3.
The pallets 9 will be moved into the housing by means of bases 11 that are sliding out of the housing for loading.
The filling doors 10 may be located either in both longer side walls of the housing or simultaneously both in one end wall and in one longer side wall.
In the housing 3, each pallet 9 is located on a base 11, movable through the filling doors 10 into and out of the housing, shown in Figure 5 and
Figure 6. In these drawings a situation is depicted where a pallet 9 together with packages 2 stacked on it has been placed on the base 11 that has been moved out through an open filling door 10.
The bases 11 may be embodied as sliding out of the housing rails.
The floor of the vending machine may be embodied, for example, as a stationary fixed roller track.
In addition, there is an air conditioner 12 in the housing 3. Preferably, the housing 3 comprises also a door 13 to allow access for the service technician into the interior of the housing 3.
The package gripper 6 moves along the housing 3 on longitudinal guide rails 14, e.g. on carriages 16 at the ends of transverse guide rails 15. There is a sledge 17 on the transverse guide rails 15 where a package gripper 6 is placed/cleaved. The package gripper 6 is movable up and down and turnable around its yaw axis. In addition, the sledge 17 has optical means 18, e.g. a camera for detection the position of the package being gripped.
The movement of carriages 16 along the longitudinal guide rails 14 takes place with an electrical drive (not shown) with transmission that is controlled with a control means 5.
The movement of the sledge 17 along the transversal guide rails 15 takes place also with an electrical drive (not shown) with transmission that is controlled with a control means 5.
The package gripper 6 is preferably embodied as a vacuum gripper that is provided with suction pads for gripping the packages.
The package gripper 6 is lowered on the package and raised up, for example, with a telescope mechanism that one end is fastened to the bottom side of the sledge 17 and on the other end of which the package gripper is located. The package gripper 6 is turnable in the horizontal position.
Also other types of mechanisms can be used for moving the package gripper in the vertical direction, e.g. pantograph-type mechanisms, etc.
There is an additional video camera 19 in the housing for monitoring the interior of the housing 3 from a distance. For example, in case of a malfunction this camera enables to assess the situation inside of the housing.
The packages 2 have been stacked on the pallets 9 by five packages per layer where each next package layer is with respect to its laying pattern 180 degrees shifted in the horizontal plane in relation to the previous layer. As can be seen from the drawings, three packages have been laid beside each other by their longer edges in one layer, and two other packages have been laid beside each other by their shorter edges, whereas their longer edges are laid against the shorter edges of the three packages placed beside each other.
The control means comprise all electronics and software necessary for control of the package gripper, making payments through the payment terminal, the control of camera or cameras in the housing, the control of optical means and operations used for detection of the position of the package being gripped, etc.
The control means also contain a communication module either for wired or wireless communication that is necessary for making payments and for the remote monitoring and control of the vending machine.
The control module is connected to the central administration server via which the vending machine is being monitored and administered. This includes the monitoring of package reserve, the environmental conditions inside the vending machine, and in case of possible malfunction, assessment of the nature of the failure with the help of a video camera or video cameras in the housing.
The vending machine operates in the below described manner.

Version 1

The buyer comes to the vending machine, selects the desired product or products on the payment terminal, i.e. a pellet package or a briquette package and the quantity of corresponding packages, and after making the payment the vending machine moves the packages one by one into a package dispensing position.

Version 2

The buyer selects a pellet package or a briquette package and their quantity and makes the payment via a mobile communication device, e.g. a smartphone. For that purpose, an application, which is downloadable into a smartphone and operating via the central administration server, is designed through which the nearest vending machine can be found, availability of the desired product (pellet package or briquette package) checked and a purchase made. When making the payment, a code will be issued for the buyer, which the buyer enters into the vending machine terminal (manually or electronically) and a package or packages purchased from the vending machine will be dispensed for the buyer.
Irrespective of which version is used for the purchase of a package or packages, the package gripper 6 is moved, for example, to the nearest pallet 9 where a suitable package 2 is located. Using the optical means 18, the control means 5 detect the position of the package and turns the package gripper 6 around its yaw axis to the suitable position and lowers the package gripper 6 onto the package 2. The package 2 is gripped with the vacuum suction pads of the package gripper 6, lifted up from the stack of the packages 2 on the pallet 9 and moved to the conveyor 7. The conveyor 7 moves the package 2 through the door (not shown) into the package dispensing module 8 that is, for example, a roller track. The end of the roller track is preferably provided with a barrier that protects the package from falling down.
The buyer seizes the package 2 from the end of the roller track of the dispensing module 8 and lifts it, for example, into their means of transport.
It is obvious for a person skilled in the art that the invention is not restricted to the embodiment examples described above and depicted in the attached drawings, but the invention has other possible embodiment options within the limits of attached claims.
