[0002]
[Background Art and Problems to be Solved by the Invention]
The vending machine 10 is provided with a vending machine main body 11 shown in FIG. 13, and stores a product 12 such as a cigarette. The vending machine main body 11 is provided with a plurality of product samples 12a to be sold, a display selection device 13 including a display unit such as a plurality of LEDs and a selection button, a money input processing device 14, a product outlet 15 and the like. When the money is input, the display unit is displayed and the selection button is pressed to sell the product 12.
[0003]
The vending machine main body 11 is provided with a plurality of product loading platforms 16 shown in FIG. 14, and a column 17 in which the products 12 are stacked in two rows is attached to the top. Further, a main controller 18 having a CPU, a ROM, a RAM and the like shown in FIG. 15 is provided inside the vending machine main body 11, and the display selection device 13 and the like are provided by inserting money into the money input processing device 14. Display operation is performed.
[0004]
A product conveyance duct 19 is attached to the front surface of the product loading platform 16 and the column 17, and the product 12 in the column 17 is pushed out by driving the product extrusion device 20 and guided to the product outlet 15.
[0005]
As shown in FIG. 16, detection devices 25 such as the product detectors 21 and 22 and the position detector 24 of the slider 23 are provided inside the product loading platform 16, and these detection signals are sent to the main control device 18. It has become. The main control device 18 that has received the detection signal from the detection device 25 displays it on the display unit, and controls the sale of the product 12 by pushing the slider 23 of the product extrusion device 20 or the like.
[0006]
17 and 18 is provided in the product extruding device 20 inside the product loading platform 16, and this is pushed and returned along a cylindrical cam 26 having a push cam 26a and a return cam 26b. It is supposed to do. The slider 23 is formed in a substantially square case. The slider 23 has a hole 27 that passes through in the front-rear direction in FIG. 17 and in the left-right direction in FIG. 18, and is attached to the hole 27 so as to pass through the cylindrical cam 26.
[0007]
The slider 23 is provided with an extrusion claw 29 rotatably attached to the shaft 28. When the product 12 is pushed out by the spring force of the spring 30 attached to the side wall, the slider 23 protrudes as shown by a solid line. When returning, it is tilted as shown by the dotted line.
[0008]
When the pushing claw 29 is located in the empty space at the right end of the product loading platform 16 in the activated state, the pushing claw 29 is projected as shown by a solid line by the spring force of the spring 30, and the product 12 is pushed out by pushing out the slider 23. When returned from the left end of the product stack 16 to the right end, the weight of the stacked product 12 is tilted as shown by the dotted line against the spring force of the spring 30 to prevent it from hitting the product 12 and damage it. I try not to.
[0009]
Such a product extrusion apparatus 20 is often used in recent vending machines because of its excellent performance, function, manufacturing cost, and the like. However, in such a slider, the slider 23 is located between the front row of products 12 (the product shown on the left side in FIG. 16) and the rear row of products 12 (the product shown on the right side in FIG. 16). When there is no product on the loading platform 16 and the product 12 is replenished while waiting at the position, there are the following problems.
[0010]
That is, when the product 12 to be replenished is dropped from the upper part and stacked on the loading platform 12, if the product 12 is mistakenly placed on the push-out claw 29 of the slider 23, the push-out claw 29 is pushed by the gravity of the product 12 as shown in FIG. May be tilted as indicated by the dotted line.
[0011]
In this state, even if money is inserted into the money insertion processing device 14 and the slider 23 moves forward to sell the product and pushes out the product 12 in the front row, the pushing claw 29 remains tilted. There is a problem that the product 12 is not pushed out and the product 12 does not reach the product take-out port 15 simply by passing the extrusion claw 29 through the lower surface of the product.
[0012]
Further, there is a problem that it is very difficult to adjust the spring force of the spring 30 when the push-out claw 29 protrudes and the spring force of the spring 30 when it is tilted. For example, when the number of products 12 in the column 17 is large, the weight of several tens of grams is received, but when the number is small, the weight of several grams is received. Even if there is this difference in weight, it is necessary to use a highly accurate spring with a force slightly weaker than the weight of the product 12 such as one cigarette in order to accurately project or tilt the extruded claw 29. is there.
[0013]
However, since the types of products 12 such as cigarettes increase and there is a slight difference in weight, it is difficult to manufacture the spring 30 accurately. There was a problem of increasing the types. Further, if the various types of springs 30 are not properly attached to the respective push tabs 29, when the push tabs 29 are returned, the arrangement of the products 12 in the column 17 is disturbed, or in the worst case, the products 12 are damaged. There was a problem.
[0014]
Therefore, according to the present invention, even if the product is mistakenly placed on the extrusion claw, the product is tilted and stored, so it can be easily determined that the product is abnormally stored, and the extrusion claw can be accurately determined regardless of the amount of the product. It is an object of the present invention to provide a product extruding apparatus for a vending machine that protrudes or tilts.
[0015]

Further, a support arm 62 is attached to the left side surface of the slider 56, and the extrusion claw 52 is rotatably attached to the support arm 62 via a rotation shaft or the like.
[0023]
Further, a groove 63 is provided on the upper front surface of the slider 56, and protrusions 64 and 65 are provided on the lower front and rear surfaces. The slider 56 is fitted to a rail (not shown) formed on the product loading platform 51. Smoothly extrudes or returns on the cylindrical cam 55.
[0024]
The claw lever 61 is formed in a disc shape. A pin 67 that engages with the push-out cam 55a and the return cam 55b of the cylindrical cam 55 is attached to the center of the lower surface of the claw lever 61, and the frame 66 is connected thereto. An engaging element 68 is attached to the outer peripheral surface of the claw lever 61 so as to be engaged with and disengaged from the pushing claw 52.
[0025]
To assemble the slider 56, the pin 67 of the claw lever 61 is inserted into the claw hole 60 of the slider 56, and the piece 66 is connected to the pin 67 from the hole 59 side. As shown in FIG. 6, the top 66 is engaged with the push-out cam 55a of the cylindrical cam 55 inserted into the hole 59 so as to be pushed out. Further, the push-out claw 52 is vertically installed on the support arm 62 of the slider 56, and the engaging element 68 of the claw lever 61 is engaged with the push-out surface of the push-out claw 52 as shown in FIG. In this way, the assembly of the slider 56 is completed.
[0026]
In order to push out the product 12 by the slider 56 having such an extrusion claw 52, the electric motor 53 of the product extrusion device 50 is rotationally driven via the main control device 18 by inserting money. By this driving, the cylindrical cam 55 rotates at an appropriate speed via the reduction gear 54, and the slider 56 is moved from the right end portion of the product loading platform 51 shown in FIG. The extruded product 12 is sent to the duct 19 at the center shown.

When the slider 56 comes to the left end, the frame 66 is switched from the push cam 55a to the return cam 55b by the vertical cam 55c of the cylindrical cam 55 as shown in FIG.
[0028]
As a result of this change, the claw lever 61 rotates about 60 ° counterclockwise, and the engaging element 68 is disengaged from the pushing claw 52 as shown in FIG. Thereby, the extrusion nail | claw 52 inclines in an extrusion direction as shown in FIG. 8 with the dead weight. Therefore, when the push-out claw 52 is returned from the left end portion to the right end portion of the commodity loading platform 51, it does not protrude from the upper surface. Therefore, it is possible to return to the starting position without touching the product 12.
[0029]
In this manner, the push-out claw 52 of the slider 56 is protruded by the claw lever 61 that engages with the cylindrical cam 55 when the product is pushed out, and the push-out claw 52 that is engaged with the cylindrical cam 55 is released when the product is returned. You can tilt it. Therefore, this extrusion claw 52 can be protruded or tilted regardless of the weight of the product 12 to be stacked and without using a precise spring. Therefore, the protrusion or tilt can be performed easily and reliably.
[0030]
In addition, such a method has an advantage that the claw lever 61 is arranged on the upper surface of the slider 56, so that it can withstand a vertical force and the like. For this reason, when the product is replenished, even if the product 12 is mistakenly stored on the extrusion claw 52, the extrusion claw 52 remains in a protruding state, so that the product 12 is stored at an angle. Therefore, since the operator who stores the product easily notices erroneous storage, the product can be immediately corrected to the normal storage state.
[0031]
11 and 12, the claw lever 71 is attached to the side wall of the slider 76 so that the push-out claw 72 protrudes and tilts. The action of the slider 76 is substantially the same as that described with reference to FIGS.
