Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a product extrusion device in a vending machine for selling cigarettes, etc.

(Prior Art) A product extrusion device in a cigarette vending machine stacks cigarettes in two rows, front and back, in a product storage section, that is, a stocker, as shown in, for example, Japanese Patent Application Laid-Open No. 56-35293. A pusher is provided in the lower part so as to be able to reciprocate in the front-back direction, and is configured to push out the bottom layer of cigarettes one by one in the front-back direction. That is, one product is carried out by the forward or backward movement of the extrusion body, and the stopping position is determined by the installation position of a micro switch that opens and closes by engaging with a part of the extrusion body. By the way, a plurality of such product extrusion devices are usually installed in parallel depending on the type of tobacco. Depending on the type of product, a product extrusion device may also be required to transport two products in one sales operation.

(Problem to be solved by the invention) In this case, it is normal to extrude one product at a time in the forward and backward movements of the extruder,
The stopping position of the extrusion body is different from when one piece is carried out in one sales operation. Therefore, when improving a product extrusion device that was previously designed to take out one item per sales operation to now take out two items per sales operation, it is necessary to at least change the installation position of the micro switch. It has to change. In order to change the installation position of the microswitch, the signal line connected to it must also be disconnected, which is a cumbersome task.

Therefore, the purpose of this invention is to provide an automatic vending machine that simplifies the work required to change the number of products delivered in one sales operation from 1 to 2 or from 2 to 1. The purpose is to provide a machine for extruding products.

Specifically, the present invention is intended to provide a product extrusion device that does not require changing the installation position of the microswitch when changing settings as described above.

(Means for Solving the Problems) The present invention provides a geared motor, a drive wheel driven by the motor, an idler wheel whose axis is parallel to the drive wheel, and a gap between the drive and idle wheels. an endless conveying body such as a chain or belt hung in an oval shape, a companion engaging portion protruding from a predetermined location of the conveying body; The drive wheel has an extrusion body having an engaged part that releases the engagement relationship with the engagement part within the range of the half circumference of the drive wheel and the floating wheel, and the products stacked in the storage part are transported to and from the extrusion body. In a product extrusion device for a vending machine, which is configured to push out and carry out products by moving and reciprocating, a first gear driven by the geared motor; A second gear is provided with a cam that opens and closes a stop switch provided adjacent to the gear, and the first and second gears are detachable.

(Function) In the product extrusion device according to the present invention, when the extruder is driven by the geared motor, the second gear rotates following the first gear. The geared motor is driven by the second gear cam until the stop switch is closed. The stop position of the extrusion body is defined by the rotation angle of the second gear. Therefore, in order to change the stop position of the extruded body, it is sufficient to leave the stop switch as it is and change the meshing ratio of the first gear and the second gear. Since both are removable, switching is easy.

(Example) Examples of the present invention will be described below. In order to simplify the explanation, one of the plurality of product extrusion devices arranged in parallel in the vending machine will be explained here as well.

1, 2, and 3 are a side view, a top view, and a bottom view, respectively, of the product extrusion device according to the present invention.

A geared motor 2 is attached to the outer bottom of one end of the frame 1, which rotates only in one direction, decelerates the rotation, and transmits the rotation to the drive shaft 3. The drive shaft 3 is the frame 1
A sprocket-type drive wheel 4 is attached to the upper part of the drive wheel 4 for horizontal rotation. A fixed shaft 5 is erected at the inner bottom of the other end of the frame 1, and a sprocket-shaped idler wheel 6 is rotatably attached to the upper part of the fixed shaft 5. In this way, both wheels 4 and 6 are disposed in a longitudinally parallel axial relationship.

Between both wheels 4 and 6, an endless conveying body 7 (a part of which is shown in FIG. 2) made of a chain is suspended horizontally, and has an oval shape when viewed from above. The endless feeding body 7 is provided with a protruding engagement portion 8 for accompanying the chain pin so as to be parallel to the chain pin. Further, on the endless feeding body 7, there is placed a push-out body 9 having a slide plate 92 attached to the upper end of a roughly shaped moving body 91. A guide rod 10 is installed on one side of the movable body 91 in the longitudinal direction of the frame body 1.
is inserted. The other side of the moving body 91 is
The lower part 93 is fitted to the side edge of the bottom wall of the frame 1. In this way, the push-out body 9 is made slidable in the front-rear direction with respect to the vending machine main body, and in conjunction with this, the slide plate 92 slides on the product placement plate 11 (not shown in FIG. 2).

Here, the movable body 91 has a long hole 94 extending between mutually parallel portions of the endless feeding body 7.
4 is fitted with a companion engaging portion 8. As a result, the extrusion body 9 moves along with the circular movement of the endless feeding body 7. Particularly, in the movement area where the accompanying engaging part 8 is adjacent to the drive wheel 4 or the floating wheel 6, that is, within the range of the half circumference of both wheels, the accompanying engaging part 8 slides within the elongated hole 94 and moves from one end. By moving to the other end, the extruded body 9 can be transported in the opposite direction.

Now, referring to FIG. 3, at the outer bottom of the frame 1, a stop micro switch S is provided adjacent to the geared motor 2 (FIG. 1). Further, a gear 12 is detachably attached to a drive shaft 3' of the geared motor 2 on the opposite side to the drive shaft 3 (FIG. 1). Further, a cam gear 13 is detachably attached to the frame 1 in mesh with the gear 12. A cam 14 attached to the gear 13 operates the micro switch S when the gear 13 rotates once.

For example, when carrying out one product in one sales operation, the accompanying hook 8 is moved to the left from position B in FIG. 2, made a U-turn, and stopped at position A. At this time, the extruder 9 extrudes one product 15 stacked on the left side in the figure, and then stops at a position where it begins to return.

Next, when carrying out two products in one sales operation, move the accompanying hook part 8 from position B in Fig. 2.
It is only necessary to make the rotation, push out one product 15 on the left side, then push out one product 15' on the right side, and return to position B again. Gear 13 performs this kind of operation.
To perform this in one rotation, the gear 13 should have a large number of teeth, and the gear 12 should have a small number of teeth.

Here, the stopping position of the extruded body 9 is set closer to the axis of the drive wheel 4 when carrying out one piece, and closer to the axis of the idler wheel 6 when carrying out two pieces (of course, the opposite is also possible). For such reasons. That is,
When stacking products 15 and 15', slide plate 9
This is to ensure that a part of the product is not stacked on the slide plate 92 in an inclined state when the product stacking device 2 is installed in any of the product stacking devices.

The gears 12 and 13 are detachable from the drive shaft 3' or the shaft 16 installed in the frame 1, and can reduce the number of products delivered in one sales operation from 1 to 2.
When changing the setting from one or two microswitches to one, it is easy to simply replace the gears 12 and 13, and there is no need to change the number or installation position of the microswitches.

Note that the endless feeding body 7 is not limited to a chain.
A belt or the like may be used, and the drive may be driven not only around the vertical axis but also around the horizontal axis.

(Effects of the invention) As explained above, according to the invention, the stopping position of the extrusion body can be set by a combination of two detachable gears.
When changing the number of products to be delivered in one sales operation from one to two, or from two to one, only the gear needs to be replaced. Furthermore, since the micro switch can be used as is, there is no need to change electrical connections, making the switching work very easy.
