The housing 1 consists of a back wall 3 and two side walls 7. The rear wall 3 is made in the shape of a rectangle, the opposite sides of which are attached two identical sides 7, protruding in one direction and arranged at right angles to the rear wall 3 (in figure 1 as an example, shows one sidewall 7). In this case, the rear wall 3 is vertically made integral with the side walls 7 of the sheet metal so that the cross section of the rear wall 3, side walls 7 forms the shape of the bracket. All of the elements of the device are located on one side of the rear wall 3. On the rear wall 3 above with the bracket fixed to the first 4 and second 5 drives (on is shown suspended by a single element).

Hereinafter, the direction "down" is made coincident with the direction of the gravity vector, under the vertical refers to the direction parallel to the gravity vector, under the horizontal refers to the direction perpendicular to the gravity vector. In this working position of the machine is vertical.

In both side walls 7 of the fixed terminals 13 arranged horizontally between the side walls 7 in parallel to each other and perpendicular to the sidewalls 7. The rods 13 perform the function of a skeleton, they fixed side walls 6, the guide 14. In this case, the rod 13 is threaded, their attachment to the side walls 7 and the bracket side walls and the guide 14 on the rods 13 carried out by means of fixing elements 8 (for example, nuts). Figure 1 in order to facilitate understanding of the drawing the threads on the rods 13 and the axial transmission 2 is not shown.

The side walls 6 mounted on the rods 13 in parallel to each other and perpendicular to the rear wall 3. The size and shape of the side walls is selected according to the size and shape of the 23 items for sale. In this case, the side walls 6 are identical, are mirror images of each other, performed mostly in the form of a parallelepiped. Each side wall 6 in the lower part has a recess 11 in which is placed and sufix is arranged brake elements 12. The side wall 6 facing the slots 11 to each other.

The space between the side wall 6, rear wall 3 and the guide 14 forms a channel 18, which can accommodate a stack of 24 items 23 and in which the stack 24 may be vertically displaced to the point where they exit from the device. Under the stack 24 in this case refers to the number of delivered exactly on each other 23.

The plunger 20 is installed in the channel 18, is connected to the first actuator 4 through a shaft of the transmission 2. The plunger 20 is designed to shift down is placed in the channel 18 of the stack 24 23 items by pressing on it from above. The first actuator 4 is made to ensure rotation of the pusher 20 around the axis. The shape and dimensions of the pusher 20 is selected so as to provide uniform pressure on the subject of 23 without damage. The plunger 20 is made in the form of a rectangular plate with rounded corners, in the middle of one side of which has a slot 19 which is perpendicular to this side, to the middle of the opposite side is attached a cylindrical element with an internal thread with which the plunger 20 is mounted on the axial transmission 2.

Axial transmission 2 is placed parallel to the side walls 6, in the middle between them in the horizontal direction. Axial transmission 2 is located near the rear wall 3. Axial transmission 2 is connected in the upper part with the first what rivada 4, it has a plunger 20 with a possibility of linear movement up and down. In this case, the axial transfer of 2 made in the form of a straight tube with external thread along the entire length.

The guide 14 has the form of a G-shaped profile, the first part 9 of which facing the inside of the channel 18 and is secured at the top and bottom on the respective rods 13, and the second part 10 which in this case is placed in the same plane with the front edges 22 of the side walls 6. The plunger 20 and guide 14 are mutually arranged so that the second part 10 of the guide 14 is always in the slots 19, preventing rotational movement of the pusher 20.

The braking elements 12 are designed to hold items 23 in the channel 18 and the friction in this case is made oblong, in the form of rubber bands round cross-section (figure 3), and, in addition, protruding above the surface of the side walls. The braking elements 12 are mounted on the side walls 6 at their lower end with a canal side 18 opposite each other and in this case fixed in the grooves 11 of the side walls (e.g., at Klee, pakatan the m figure 3 conditionally) parallel to each other in a vertical direction, i.e. oriented in the direction of movement of the follower 20 along the axis 16 up and down.

Vending machine provided with a stopper 15, designed to stop 23 in the channel 18. The stopper 15 is installed in the continuation of the target channel 18 below the brake elements 12 (under the target in this case refers to the cross-section of the channel 18). The stopper 15 is attached to the axis 16, it is connected with the second actuator 5 and thus can be moved out of the target channel 18 and away from him. The second actuator 5 is designed to provide rotational movement of the stopper 15. In this case, the stopper 15 is made in the form of an l-shaped elongated plate.

The axle 16 is connected at the top with the second actuator 5 with the possibility of rotation on ±90°. The axis 16 is placed coaxially inside the axial transmission 2, and its length is greater than the axial length of the transmission 2, and she's out of axial transmission 2 from the end opposite to the end fixed in the second actuator 5. The axle 16 has the form of a rod of circular cross section of such a diameter that can rotate independently of the axial transmission 2.

Below the side walls, at some distance from them, to the rear wall 3 and side walls 7 at right angles attached to the tray 17. The distance between the lowest point of the side walls and the tray 17 is selected in order to provide the possibility of loss of item 23 of the channel 18 and dalnas is its movement. In this case, the tray 17 has a rectangular shape and is made of sheet metal.

The operation of the device, illustrating the case of inventions

The device operates as follows (hereinafter referred to as example illustrates the operation of the vending machine).

Pre side walls 6, enshrined in this case, with the possibility of changing the position, placed and fixed on the rods 13 so that the dimensions of the channel 18 corresponded to the dimensions of the 23 items intended for sale.

Then the device is mounted in a vertical position in its intended location (e.g., inside the machine for sale cigarette packs). Made the necessary connections (for example, actuators are connected to a power source and control elements; not shown). Vending machine is in the initial operating position in which the plunger 20 is in its extreme upper position, the stopper 15 is rotated so as to prevent items from dropping 23 of the channel 18.

Guide 14 is detached from the top of the respective rod 13, is shifted out. After that, items 23 stack 24 is loaded into the channel 18 under the plunger 20 to fill the channel 18. The offset to the side of the stack 24 23 in the channel 18 limited lateral walls 6, the offset limited forward and backward direction is shining 14 and the casing 21 (figure 2). Figure 2 to facilitate understanding of the drawing objects 23 of the stack 24 is shown with a gap between them. Thus the subjects 23, located above the brake elements 12 are held in the stack 24 only under the action of gravity, and objects 23 in contact with the brake elements 12 are held from falling out of the brake elements 12 from opposite sides (Fig 3). In addition, the bottom of the stack 24 item 23 abuts against the stopper 15, and the top item 23 is under the plunger 20 with a gap not exceeding the thickness of the object 23 (hereinafter, the thickness of the object 23 is vertically located in the stack 24 item 23).

Guide 14 is returned to its original position, is fixed on top of the corresponding rod 13, while the plunger 20 is set so that the first part 9 of the guide 14 is placed in the slot 19 of the pusher 20. On a signal from the control elements is driven by the first actuator 4 through which rotational movement is transmitted to the axial transmission 2, the plunger 20 in its thread moves down until it touches the top of the object 23 in the stack, after which the device is stopped at the next signal from the control elements. Vending machine is ready for operation.

To extract the subject 23 from the vending machine by a signal from control elements again is driven by the first actuator 4, cher is C him rotational movement is transmitted to the axial transmission 2, the plunger 20 in its carving is shifted down by clicking on the stack 24 23 above. The amount of displacement of the pusher 20 is equal to or slightly greater than the thickness of the object 23 and is determined by the duration of the first actuator 4, which, in turn, is set by signals from the control elements. Simultaneously, the second actuator 5, from him rotational movement is transmitted along the axis 16 of the stopper 15. The stopper 15 is rotated 90°, freeing the bottom item 23 of the stack 24, which is kept from falling only brake elements 12.

Upon further displacement down the stack 24 23 under the pressure of the pusher 20, the bottom item 23 extends beyond the side walls 6, is not charged more on the friction under the action of gravity falls down into the tray 17 (figure 2). At the same time, the stack 24 23 continues to move down and the next item 23 of the stack 24 is moved to the lowest position. At this point, the signals of the control elements of the first actuator 4 is turned off, the axial transmission 2 stops rotation, the plunger 20 is stopped and the stack 24 23 ceases to shift down. Simultaneously activates the second actuator 5, the axis 16 is rotated -90°, the stopper 15 is returned to its original position, preventing the loss of the next item 23. After that, the second actuator 5 is turned off. The device is ustanavlivaetsya until the next power-on signal from the control elements.

The implementation of the vending machine in case 1 holds two side walls 6, installed in parallel with the formation of the channel 18; with the plunger 20 mounted in the channel 18 with the possibility of moving up and down and connected to the first actuator 4; brake elements 12 mounted on the side walls 6 at their lower end side of the specified channel 18 and opposite each other, made oblong with orientation in the direction of movement up and down the specified pusher 20 and protruding above the surface of the side walls; with the G-shaped stopper 15 installed in the continuation of the target channel 18 below the brake elements 12, with the possibility of extension/hide, simplifies the design of the vending machine and provides increased reliability.
