DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a merchandise delivery device for a vending machine.

[0002]

2. Description of the Related Art Conventionally, in a vending machine, as a product sending device that is less affected by the shape or size of a product, a product is placed on a horizontally extending conveyor, and a product sending command is issued. There is known a product transport shelf device that transports products to a product outlet side by driving the conveyor with a drive motor based on the drive motor.

For example, Japanese Utility Model Publication No. 1-10706 (G
07F11 / 58), a shaft provided with a pair of right and left sprockets is provided rotatably on the front and back between the side plates of the base, and an endless transport chain is stretched between the sprockets.
A structure is shown in which a drive motor is connected to one of the shafts via a speed reduction mechanism, and the driving force of the drive motor conveys the goods on the transfer chain in the horizontal direction.

[0004]

In a conventional structure for mounting a drive motor in a product transport shelf apparatus, a rotary shaft located at the end of a speed reduction mechanism of the drive motor is applied from the side to a shaft on which a sprocket is mounted. In this state, the mold part itself is firmly screwed to a side plate or another mounting plate by using a plurality of screw holes drilled in a mold part having a built-in speed reduction mechanism. Was.

Therefore, unless the positional relationship between the plurality of screw holes for fixing the drive motor and the shaft is strictly controlled, the shaft and the rotation shaft on the drive motor side can be coaxially connected. However, there is a problem that the so-called centering work at the time of mounting the drive motor becomes extremely complicated. Therefore, the present invention focuses on the fact that the driving device of the product delivery device is a low-speed rotating motor, and there is little need for strong fixing, and the number of parts for mounting the driving device and the automatic vending with reduced mounting work have been reduced. It is an object of the present invention to provide a product delivery device for a machine.

[0006]

That is, according to the present invention, a commodity delivery apparatus 1 for a vending machine according to the present invention comprises a pair of shafts 3 and 4 provided on the side walls 2A and 2B of a substrate 2 so as to be rotatable in the horizontal direction. The transport members (transport belts) 14 and 16 are stretched and the side walls 2A and 2B
Is driven in a substantially horizontal direction by driving the shaft 3 by a driving device (drive motor 9 and mold unit 11) disposed on the side of the shaft. When the rotating shaft 12 of the driving device (the driving motor 9 and the molding unit 11) is connected to the shaft 3 from the side, the rotation of the driving device (the driving motor 9 and the molding unit 11) around the shaft 3 is controlled.

11), and one end (the other end surface) 8B is provided with a rotation restricting portion (fixed frame) 10 which is provided so as to be able to contact with the rotation restricting portion (fixed frame).
Frame 10) and the other end (one end face) 8
A presses the driving device (the driving motor 9 and the molding unit 11) from the side while the rotating shaft 12 is connected to the shaft 3 , and moves the driving device (the driving motor 9 and the molding unit 11) to the side. And a pressing member (pressing plate) 8 for preventing the occurrence of the pressure.

[0007]

According to the merchandise delivery device 1 of the vending machine of the present invention, the driving device (the driving motor 9, the molding unit 1) is disposed on the shaft 3 around which the conveying members (conveying belts) 14 and 16 are stretched.
1) The rotating shaft 12 is connected, and the rotation restricting portion (fixed frame) 10 restricts the rotation of the driving device (the driving motor 9 and the mold portion 11) about the shaft 3 and the pressing member (pressing member). The drive device (drive motor 9,
If the mold part 11) is pressed down, the lateral movement of the driving device (the drive motor 9, the mold part 11) is prevented,
The connection between the shaft 3 and the rotating shaft 12 is not released. That is, the mounting operation of the driving device (the driving motor 9 and the molding unit 11) to the commodity delivery device 1 is performed by rotating the rotating shaft 12 of the driving device (the driving motor 9 and the molding unit 11) to the shaft 3.
And at the same time restrict the rotation of the driving device (drive motor 9 and mold portion 11) itself by a rotation restricting portion (fixed frame) 10, and finally press the pressing member (pressing plate) 8 The operation is completed only by mounting and pressing the driving device (the driving motor 9 and the mold portion 11) from the side. The rotation restricting portion (fixed frame) 10 may restrict the rotation of the driving device (the drive motor 9 and the mold portion 11) in one direction. There is no need to strictly manage relationships. Further, fixing work such as screwing is performed only when the holding member (holding plate) 8 is finally attached, and the number of parts and the number of working steps are significantly reduced.

[0008]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view, FIG. 2 is a side view, FIG. 3 is a rear view, and FIG. 4 is a front view of the commodity delivery apparatus 1 of the present invention. The product delivery device 1 is installed in a vending machine (not shown) at a plurality of stages substantially horizontally.
The shafts 3 and 4 are rotatably mounted over the front and rear end portions of the side walls 2A and 2B of the substrate 2, and a pair of sprockets 6 and 7 are located on the shafts 3 and 4 inside the side walls 2A and 2B, respectively. Is attached. A guide plate 5 is attached to the side wall 2B and extends upward to prevent a large movement of the product to the side. Further, a fixed frame 10 (rotation restricting portion) for fixing the commodity sending apparatus 1 to the vending machine is provided extending in the front part of the substrate 2 to the left and right. A drive motor 9 is attached to the outside of the guide plate 5 by a pressing plate 8 as a pressing member. The driving force of the drive motor 9 is fixed at the end of the speed reduction mechanism via an unillustrated speed reduction mechanism stored in a mold unit 11 that forms a drive device together with the drive motor 9 while the drive motor 9 is fixed. Part 11
To the rotating shaft 12 protruding from side to side, and further this rotating shaft 12 is connected to the shaft 3 by a joint 13,
The driving force of the driving motor 9 is transmitted to the shaft 3.

Endless transport belts 14 and 16 as transport members made of thin synthetic resin or rubber are stretched in the horizontal direction between the sprockets 6 and 6 and between the sprockets 7 and 7 of the shafts 3 and 4, respectively. I have. This transport belt 14,
Reference numeral 16 is engaged with the sprockets 6 and 7, and when the rotation shaft 12 is rotated by the rotation of the drive motor 9, the driving force is transmitted to the shaft 3 via the joint 13, and the sprockets 6 and 7 By being rotated, the transport belts 14 and 16 are driven to rotate upward at a relatively low speed in FIG. An elongated product placing member 18 made of, for example, an elastic polypropylene resin is detachably attached between the transport belts 14 and 16.

Here, the mounting of the drive motor 9 for driving the transport belts 14 and 16 will be described. As shown in FIGS. 5 and 6 in an enlarged manner, the mold portion 11 has a rectangular side surface and a substantially inverted L-shaped cross section, and a drive motor 9 is mounted on a mounting surface 11A corresponding to the bottom of the L shape. Installed. As described above, the drive motor 9 drives the product placing member 1 of the transport belts 14 and 16 at a relatively low speed.
8 transports the goods, and thus does not need to be firmly fixed as in a high-speed rotation motor. Therefore, when attaching the drive motor 9, first, the rotating shaft 12 projecting left and right from the mold part 11 is connected to the joint 13 of the shaft 3 from the side (the right side in FIG. 4). At this time, as shown in FIG. 6, the fixed frame 10 is positioned so as to enter the corner portion P formed by the drive motor 9 and the mounting surface 11A. The rotation of the part 11 is regulated by the fixed frame 10. In particular, due to the reaction by the driving force of the driving motor 9 as described above, the driving motor 9 and the molding unit 11 are about to rotate counterclockwise in FIG. Is in contact with the fixed frame 10, so that such rotation is prevented.

Next, in this state (FIG. 6), the holding plate 8 is attached. The holding plate 8 is bent stepwise as shown in an enlarged view in FIG. 5, and has an insertion hole 34 larger than the rotary shaft 12 on one end surface 8A. One end face 8A around the insertion hole 34 is applied to the mold portion 11 from the side, and the rotary shaft 12 is inserted into the insertion hole 34 to avoid the mold portion 11,
The other end surface 8B is fixed to the front surface of the fixed frame 10 by screws 33 using screw holes (not shown) formed in the other end surface 8B. As a result, the mold portion 11 is pressed against the one end face 8A of the holding plate 8 from the side and is prevented from moving sideways, and the connection between the shaft 3 and the rotating shaft 12 at the joint 13 is securely held. Is done.

In particular, since the fixed frame 10 only needs to secure a positional relationship in which it comes into contact with the mounting surface 11A of the mold portion 11 as described above, the dimensions of each member necessary for centering the shaft 3 and the rotating shaft 12 are required. Strict management of the relationship and complicated centering work are not required. In addition, since the fixing frame 10 for fixing the product delivery device 1 to the vending machine regulates the rotation of the drive motor 9 and the mold portion 11, the special members required for the attachment are the holding plate 8 and the screw 33. Only a plurality of screws are not required, and the number of parts can be reduced. At the same time, since only one screw fixing operation is required, the number of mounting steps is extremely small, and the assembling workability is significantly improved.

As described above, the drive motor 9 and the mold 1
A loading plate 24 is attached to the front end of the substrate 2 on the product loading side of the product delivery apparatus 1 to which the product 1 is attached. The loading plate 24 is inclined so that the front side is high and the rear side is low so as to have a height corresponding to the front portions of the transport belts 14 and 16, and a loading switch lever plate 27 (not shown) is provided on the inclined surface 26. Have been. The lever plate 27 is always held on the inclined surface 26 by a spring (not shown) at a small distance from the inclined surface 26 as shown in FIG. 2 and is pressed against the inclined surface 26 against the spring force. Then, the loading switch drives the drive motor 9.

When the goods are loaded into the goods delivery apparatus 1, the goods are rolled along the loading plate 24 and dropped one by one onto the goods placing members 18 of the conveyor belts 14, 16. At this time, since each product pushes the lever plate 27, the drive motor 9 is driven each time to move the sequentially loaded products upward in FIG. Thus, the loading of a plurality of products into the product delivery device 1 is performed smoothly. Further, even if a product stops halfway without an interval of one piece, the drive motor 9 is driven by pushing the lever plate 27 by hand, so that the problem can be solved by arbitrarily adjusting. .

On the other hand, a stopper member 29 is provided at the rear end of the substrate 2 on the product delivery side of the product delivery device 1. The stopper member 29 extends from the base plate 2 so as to be able to lock the product loaded on the product placing member 18, and has both ends of the shaft 4.
Is rotatably supported at The stopper member 29 is always moved by the elastic force of the coil spring 31,
16 is urged in the opposite direction to the rotation direction. On the side wall 2B corresponding to the stopper member 29, a lock mechanism 32 for restricting the rotation of the stopper member 29 is provided. The lock mechanism 32 holds the stopper member 29 in a product standby position where the product can be locked as indicated by a broken line in FIG.
When the products are moved rightward in FIG. 2 by the driving of the rollers 4 and 16 and come into contact with the stopper member 29, the stopper member 29 is rotated to the product locking position shown by the solid line in FIG. Restrict rotation to

Then, when a sales signal is generated from a vending machine control device (not shown) by the insertion of money by the customer, the lock mechanism 32 releases the rotation restriction of the stopper member 29 and drives the drive motor 9. As a result, the first product rotates the stopper member 29 to the product delivery position indicated by the dashed line in FIG. It is transported and discharged to the product sales outlet of the vending machine. When the product is delivered to the elevator, the stopper member 2
9 is returned to the commodity standby position again by the coil spring 31. On the other hand, the drive motor 9 is still driven, and when the stopper member 29 is rotated again to the product locking position by the contact of the next product, the rotation of the stopper member 29 is regulated by the lock mechanism 32, and furthermore, The drive motor 9 is stopped by a switch (not shown) in the lock mechanism 32, and the product delivery operation ends.

If the stopper member 29 is not rotated from the product standby position to the product locking position by the driving of the drive motor 9, it is determined that the product is sold out by a switch (not shown) in the lock mechanism 32. Become.

[0018]

As described above in detail, according to the commodity delivery device for a vending machine of the present invention, the rotation of the drive device is restricted by the rotation restricting portion, and in this state, the drive member is driven laterally by the pressing member. Since the movement of the device is prevented, the number of parts for mounting the drive device and the number of steps for mounting the device can be significantly reduced, so that the overall manufacturing cost can be significantly reduced.
