Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a high-speed vending machine applied to high-speed automatic vending of relatively thin paper such as newspapers and magazines that are automatically sold unmanned.

[0002]

[Prior art]

 In the past, large-scale sales of newspapers are sold at stations such as at stations other than home delivery, and it is common for customers to pull out a large number of high-priced newspapers one at a time and pay for them, which can be done in large quantities in a short time. It cannot be sold. In the past, there were unmanned newspaper vending machines, but there was a limit to the number of copies that could be sold because there was no newspaper lifting mechanism and the delivery speed was slow.

[0003]

[Problems to be solved by the device]

 Conventional newspaper vending machines do not have an elevating mechanism in the newspaper storage section and are fixed at a fixed height, so the number of copies sold per sheet was extremely small due to the positional relationship with the newspaper outlet. Moreover, since the carry-out mechanism is complicated, it is difficult to drive at high speed, and the height of the vending machine is often limited when installed at a station shop. Furthermore, because the mechanism is a link type, the number of storage units and types of storage paper is small despite the fact that the vending machine is large, and since the movement of newspapers is not detected, there are variations in delivery, and there is also the problem of delivery failure. . The present invention has been proposed to solve the above conventional problems.

[0004]

[Means for Solving the Problems]

 For this reason, the present invention has an elevating shelf for stacking objects to be sold made of relatively thin paper such as newspapers and magazines, an elevating mechanism for elevating and lowering the elevating shelf, and pressing the upper surface of the uppermost object. In addition, it is equipped with a pressing and transporting mechanism that has a unloading roller that rotates so as to send the topmost object toward the unloading port. The unloading roller has multiple rows of needles attached to its outer peripheral surface and is rotatable on the frame. Only one roller shaft is supported on one side of the roller shaft so as to hit the center of the object to be sold. This is a means for solving the problem. Further, in the present invention, an auxiliary roller that can be moved up and down and has a certain weight is attached near the exit of the object to be sold in front of the exit roller, and the exit roller and the auxiliary roller are in a straight line. In addition, two rollers are arranged so that they are in contact with the object to be sold at the same time, and this is a means for solving the problem.

[0005]

[Action]

 In the present invention, a large amount of objects can be stored by lowering the elevating shelves for storing the objects to be sold, and the slope or curved surface of the uppermost objects to be sold, which occurs when a large number of objects are stacked, is placed at the center. The pressing / conveying mechanism that has one carry-out roller always hits the center of the rising object and makes sure that each copy is stopped at a fixed position with a constant pressing force, so that the next object can be carried out reliably. become able to. In addition, by mounting the needles in multiple rows, it is possible to carry out the goods to be sold straight with a reliable carrying output.

【Example】

 The present invention will be described below with reference to the embodiments of the drawings. FIGS. 1 to 4 show the embodiments of the present invention. 1 to 4, a perspective view of a high-speed vending machine is shown. 1 is a coin slot, 2 is a change receiving port provided at a high position of the vending machine, and 3 is a selection port. Buttons 4 are outlets for the sale target 11. The sale target 11 is set in a sellable state on the upper and lower elevating shelves and the lower elevating shelf which are not shown. FIG. 2 is a plan view of the pressing / conveying mechanism, FIG. 3 is a side view of FIG. 2, and 5 is a carry-out roller having a plurality of rows of needles attached to one end of a roller shaft 20 rotatably supported by the frame 13. Only one is fixed, and it projects downward from the notch 21a of the drive unit mounting plate 21. Further, the frame 13 can swing back and forth around a pin 12 supported by a bracket 21b mounted on a mounting plate 21, but the frame 13 is on the side opposite to the pin 12 with respect to the roller shaft 20. A pull-out spring 14 having one end fixed to a mounting plate 21 biases the carry-out roller 5 to a position where the carry-out roller 5 comes into contact with the central portion of the object 11 to be sold. Reference numeral 17 denotes a pressing pressure detection sensor for the unloading roller 5, which is activated when the pressing force most suitable for unloading the object 11 for sale is reached.

Reference numeral 15 denotes a drive motor fixed to the end surface of the frame 13 on the pin 12 side, which drives the pulley 19 and is provided between the pulley 19 and the pulley 20 a loosely fitted to the roller shaft 20. A toothed belt 18 is hung. Reference numeral 16 denotes an electromagnetic clutch, which can rotate integrally with the roller shaft 20 on the roller shaft 20 and slide on the roller shaft 20 to rotate the pulley 20a integrally with the roller shaft 20. It has become so. In addition, an auxiliary roller 22 that can move up and down and has a certain weight is attached near the exit of the object 11 to be sold in front of the exit roller 5, and the exit roller 5 and the auxiliary roller 22 are in a straight line. Two rollers in front of and behind the same are arranged so as to contact the object to be sold at the same time.

Next, the operation of the embodiment shown in FIGS. 1 to 4 will be described. The object to be sold 11 is set in the upper and lower stages in a salable state. Here, when a coin is inserted from the coin insertion slot 1, the salable lamp incorporated in the selection button 3 is turned on. In this state, for example, when the lower selection button 3 is pressed, the carry-out roller 5 of the lower drive unit is rotated, and only one copy of the sale object 11 is instantaneously carried out from the carry-out port 4. At this time, the carry-out roller 5 is pressing the target object 11 with an appropriate pressure while rotating. Explaining this point in more detail, the object to be sold 11, which has been lifted up from the lower side by the elevating mechanism, hits the carry-out roller 5 protruding below the drive unit mounting plate 21, but is pushed up further. At this time, the pulling force of the spring 14 gradually becomes stronger, and when the position of the pressing force most suitable for carrying out the object 11 is reached, the pressing pressure detection sensor 17 operates and stops the rise of the object 11. Ready for sale.

Next, when the sale selection button 3 is pressed, the carry-out roller drive motor 15 rotates, and the roller shaft 20 connected by the toothed belt 18 simultaneously rotates via the pulley 20 a and the clutch 16. That is, an electromagnetic clutch 16 is attached to the roller shaft 20, instantaneously transmits the rotation of the toothed belt 18 to the roller shaft 20, and instantaneously cuts off the rotation by a stop command of the carry-out roller drive motor 15 to be sold. Stop the unloading of the object 11. Further, when the object 11 to be sold is taken out, the carry-out roller 5 is pressing the object 11 to be sold, but since the electromagnetic clutch 16 is OFF, it is in a free state and can be easily taken out. In this way, by keeping the contact pressure between the object to be sold 11 and the carry-out roller 5 constant, it is possible to reliably carry out the product one by one. As a method for making the contact pressure constant, a combination of the strain amount of the tension spring 14 and the sensor is used in the above embodiment, but as another method, a strain gauge is used instead of the spring for detection. As a simpler method of detecting the push-up angle of the roller using a potentiometer or position sensor, the same effect can be expected by simply attaching the dead weight of the carry-out roller or a weight to the carry-out roller.

Next, a method of stopping the carried-out sale object 11 will be described. At the moment when the sale-target article 11 exits from the carry-out port 4, a detection sensor (not shown) provided in front of the carry-out port 4 detects this. Then, the carry-out roller drive motor 15 is stopped immediately or after a preset time. This allows the amount of the sale target 11 to be ejected from the carry-out port 4 to be freely controlled, and can be stopped at a position where the purchaser can easily take it. The same result can be obtained by rotating the carry-out roller drive motor 15 for a preset time without using the sensor.

FIG. 4 is a view of the pressing and transporting mechanism of FIG. 2 as viewed from the front (view from the arrow A). When the objects to be sold 11 are piled up in a large amount due to folding, etc., the uppermost part becomes inclined or curved, and if there are two left and right carry-out rollers, a left and right swing mechanism etc. to prevent one-sided contact is required. However, in the present invention, since the carry-out roller 5 and the auxiliary roller 22 are arranged in a straight line before and after the central portion, the product 11 to be sold can be reliably carried out straight without being affected by the inclination or the curved surface. it can.

[0012]

[Effects of the Invention] The vending machine of the present invention aims for rapid mass sales at the time of a rush hour at a station, and it is a necessary condition to minimize troubles during the automatic sales. Therefore, according to the carry-out roller and the auxiliary roller arranged in the front and rear of the center according to the present invention, there is no one-sided contact as in the case where two carry-out rollers are provided on the left and right, regardless of the inclination or curved surface of the carry-out object. With the pressing and discharging mechanism, it is possible to surely carry out the product, and it is possible to eliminate the defective delivery due to one-sided contact of the carry-out roller and to more reliably sell the product.
