Abstract

PURPOSE:To eliminate non-merchandise sales and to prevent from leaving merchandise unsold by performing two-piece sales while carrying out merchandise one by one from two-line columns. CONSTITUTION:The identical merchandise 3 are stored in merchandise columns 1 and 2 to be turned to the column of two-piece sales setting, a bending motor 4 is rotated positively and reversely once at a time by one operation of a merchandise selection depressing button 20, the merchandise 3 is successively carried out one by one from the two-line columns 1 and 2 respectively. Since the merchandise 3 is carried out one by one from the two-line columns 1 and 2 to perform the two-piece sales, the two-piece sales can be executed until a sellout switch 13 works while there are no merchandise 3 in respective colums 1 and 2 in the case of housing as many merchandises 3 as that in these columns 1 and 2. Thus, the two-piece sales can be surely executed without generating the merchandises left unsold while turning the sellout switch 13 to the standard state of one-piece sale.

Description

[Detailed description of the invention] [Industrial application field]

In this invention, one bend motor is provided in common for each of two adjacent product columns (referring to the unit of storing and carrying out each product, hereinafter simply referred to as a column), and the bend motor is rotated in the forward or reverse direction. Regarding the vending machine that carries out products from the column, in particular, 2 is used to carry out two of the same product in succession with one operation of the product selection push button.
This invention relates to an individual sales control device.

[Conventional technology]

When selling products in units of two in the above-mentioned vending machine, conventionally the bend motor was rotated forward or reverse twice to eject two products from the same column.

[Problem to be solved by the invention]

However, in general, the sold-out switch in each column detects sold-out after the last item is gone, and if there is even one item left, the sold-out signal will not be sent, so the above In conventional control, a sales command to sell two items may be issued when there is only one item left, and in that case, the operation of the second bend motor would be a short sale, causing damage to the user. become. As a countermeasure, it may be possible to send out a sold-out signal when there is only one item remaining for columns that are set to sell two items, but this method requires the trouble of changing the position of the sell-out switch. Above, there may be cases where one product remains unsold.
It's not really a good idea. An object of the present invention is to provide a two-piece selling control device for a vending machine that can reliably sell two pieces without causing unsold items while keeping the sell-out switch in the standard state of selling one piece. It is something. [Means for Solving the Problem] This invention stores the same products in two columns.
The column is set to sell individually, and each press of the product selection push button causes the bend motor to rotate forward and reverse once.
It is assumed that one product from each column is successively carried out.

[For use]

Since the products are carried out one by one from the two columns and sold in two pieces, if the same number of products are stored in each column, it will take two until the products in each column are completely exhausted and the sell-out switch is activated. Individual sales can be carried out, and there will be no unsold items.

【Example】

Hereinafter, the present invention will be described in detail regarding a vending machine having a direct stacking type pend rack. First, Figures 1 and 2 show the configuration of Pendrack, with Figure 1 (A) being a front view, Figure 1 (B) being a side view,
FIG. 2(A) is a plan view taken along the line ■■ in FIG. 1(A), and FIG. 2(B) is a side view taken along the line BB. In the figure, 1 and 2 are two adjacent columns, 3 is the same number of products of the same type (drinks in paper cartons) stored vertically in columns 1 and 2, the same number on the left and right, 4
is a bend motor common to columns 1 and 2; 5 is a drive shaft of the bend motor 4; 6 is a cam that rotates integrally with the drive shaft 5;
7, a reset switch operated by the cam 6; 8, a stop switch; 9, a pair of left and right flappers arranged on both sides of the drive shaft 5 in contact with the second product 3 from the bottom;
0 is a half-moon cam connected to the tip of the drive shaft 5, 11 is a cantilevered support plate that is supported by the half-moon cam 10 and holds the product 3, and 12 is a sold-out plate that is in contact with the bottom product 3. Actuator, 13 sold out actuator 12
This is a sell-out switch operated by . As shown in FIG. 2, the reset switch 7 is operated by a disk 14 of the cam 6, and the stop switches 8, which are stacked one above the other, are similarly operated by a pair of arms 15 on different levels. There is. The operating principle of such a Pendrack is as follows. The bend motor 4 is energized from the illustrated state, and when the drive shaft 5 rotates 90 degrees in the forward direction (clockwise when viewed from below), the stop switch 8 comes into contact with the arm 15, ONL, and the bend motor 4 is stopped. On the other hand, at that point, the flapper 9 on the left side of the figure is pushed by the cam 16 integrated with the drive shaft 5, lifts up as shown by the two-dot chain line, and bites into the second product 3 from the bottom of the column 1. At the same time, 90
Once the half-moon cam 10 has rotated several times, the left support plate 11 is released, so that the support plate 11 hangs down about the pin 17 as shown by the two-dot chain line. As a result, the lowest product 3 falls due to gravity. Next, after a predetermined time (about 1 second) required for the product 3 to fall, the vent motor 4 is energized again. Therefore, when the drive shaft 6 rotates 90 degrees in the opposite direction, the reset switch 7 falls into the recess 14a of the disk 14 and reaches 0FFL.
The bend motor 4 stops. At that point, the flapper 9 and the half-moon cam 10 return to the state shown. The product 3 in the column 2 is also carried out in the same way by rotating the bend motor 4 from reverse to forward rotation. Next, the control block diagram shown in FIG. 3 will be explained. In the figure, reference numeral 18 denotes a control section consisting of a microcomputer that controls the entire vending machine, and this control section 18 includes the above-mentioned bend motor 4, reset switch 7, stop switch 8,
, a sell-out switch 13, a coin mech 19, a product selection pushbutton 20, and a sell-out lamp 21 are connected. When a coin 22 is inserted into the coin mech 19 and the product selection push button 20 is pressed, the control unit 18 rotates the bend motor 4 once in the forward direction and then in the reverse direction to move the product 3 to the columns 1 and 2.
Have them removed one by one. Further, when the lowest product 3 is exhausted and the sell-out switch 13 is turned on, the sell-out lamp 21 is turned on to stop further sales. Now, the two-piece selling control for the product 3 according to the present invention will be explained according to the flowchart shown in FIG. First, in step S1, a check is made to see if the push button 2o has been pressed, and if it has not been pressed, a check is made in step S2 to see if there is a column 1-2 set to sell two pieces. If there is column 1.2 with 2-piece sell setting, it is checked in step S3 whether there is a sold-out column, and if there is no sold-out column, the process returns to step S1, but if there is a sold-out column, step S4 is performed. The sold-out lamp 21 is turned on and the process returns to step S1. Also, if there is no column 1.2 set to sell 2 pieces in step S2, it is checked in step S5 whether there is a sellout in the 1 piece sell column, and if there is no sellout, the process returns to step St.
If there is, the corresponding sold-out lamp is lit in step s6. Next, when the product selection button 20 is pressed in step S1, the process goes to step S7, and it is checked whether it is a two-piece selling column, and if it is a two-piece selling column, the corresponding bend motor 4 is first rotated in the normal direction in step S8, and the left column is 1 of products 3 are sold, and in step S9, 1 is added as the number of sales in the left column 1, and the process goes to step S10. In step S10, the bend motor 4 is reversed to sell the products 3 in the right column 2, and in step Sll, 1 is added as the number of sales in the right column 2. Then, in step S12, the amount of sales for two items is added to column 1 or 2 corresponding to the item selection button 20 pressed, and the process returns to step S1. 2 in step S7
If it is not sold individually, the process goes to step S13, where the column for selling one item corresponding to the product selection push button 20 is sold;
In step S14, the number of sales and the sales amount are added to that column, and the process returns to step S1.

【Effect of the invention】

According to this invention, since the products are carried out one by one from the two columns and sold in twos, short sales and unsold items are eliminated. Also, when two columns of the same product are placed next to each other, the products in both columns are reduced evenly, instead of being reduced one-sidedly, unlike when two products are continuously carried out from the same column. Therefore, there is no need to worry about old products being left in the negative column.
