Abstract

The present invention relates to a product vending device for can vending machines. More specifically, the product outlet of a conventional can beverage vending machine has a opening door structure and is located at the lower part of the vending machine in the same line as the coin inlet of the upper part of the vending machine. The outlet 1 is installed to raise the falling product, automatically open the door 2, and provide a product lift-out device, that is, a lift mechanism, to allow the product to be taken out of an upright state, thereby making the ejection operation more convenient. I would like to.

To this end, the present invention induces that the funnel chute 11 seats on the catcher 5 so that the product stored in the can lacquer R falls freely by the ejection mechanism E. 5) rotates and rises in an upright state. At this time, the associated blowout door 2 is opened and opened, and after the user takes out the product, the empty catcher 5 is returned to its original position, and the blowout door 2 is automatically closed by its own weight.

Description

Product lifter for can vending machines. {THE LIFT MECHANISM FOR CAN DRINK VENDING MACHINE}

The present invention relates to a product lift discharge device (LIFT MECHANISM) for can vending machine to improve the way of discharging the product from various can drink vending machine from the bottom drop type to the top lift type.

Conventional can drink vending machine drops the product stored in the can lacquer (R) of the cabinet to the flat chute through the eject mechanism (E) is sporadically discharged to a wide discharge container located below the outer door (OD), the door structure It has a manual casement.

Afterwards, the user should bend down, check with the naked eye, open the drawer door, and put his hand inside the discharge bin to take out the lying product. Can vending machine composed of only the bottom drop discharge method has a structural disadvantage accompanied by inconvenience.

Therefore, the present invention was devised to solve the above problems, and improved the discharge process after free fall of the product from the ejection mechanism (E) of the can lacquer (R) from the bottom drop type to the top lift type, but the door (2) The purpose is to implement a lift mechanism of the structure that can be automatically opened and the product can be taken out upright.

<Explanation of symbols for main parts of drawing>

OD: Outer door ID: Insulation door inside

R: Can Lacquer (Storage) E: Eject Mechanism (Product Discharge Controller)

1: product outlet 2: door

4: catcher 6: ball screw shaft

10: passage door 15: elevating control panel

The product selected according to the user's selection button operation is applied to the can vending machine that vertically falls from the can lacquer (R) of the cabinet via the ejection mechanism (E). The funnel chute 11 is installed under the can lacquer R as shown.

On the lower end of the insulated door ID, an aisle door 10 serving as a heat insulator and a passage is installed.

The small motor 8, the condensed ball screw drive mechanisms 6, 7, 9, the catcher 5 receiving the product, the automatic opening and closing door 2, and the elevating control panel 15 controlling the elevating drive are integrated. Integrated into the outer door (OD)

Closing the door (OD, ID) was configured to form a joint structure that facilitates the flow of the product.

According to the structural features of the present invention

The chute 11 is a kind of hopper type in which the cylindrical can and the bottle product are rolled and slipped and enters the aisle door 10 of the insulated door ID, and the rolling friction is not a problem, but the sliding angle is low when the inclination angle is low. Since the flow of the product may be stopped due to the high coefficient, the vibrator (not shown) may be installed on the back of the chute 11 to vibrate to smooth the flow. To overcome and glide the product.

The catcher box 4 is fastened to one side of the ball screw nut 9, and the catcher 5 is coupled therein to rotate during the ascending operation so that the product and the catcher are upright.

When the catcher 5 is in the standby state, the plate spring 13 of the right triangular protrusion 12 attached to the fixing plate is in close contact with the passage door 10 to maintain the same inclination angle as the chute 11.

In the lifting operation of the catcher box (4) is characterized in that the access door 2 is opened and closed in connection with this.

The drive means are preferably characterized by high precision LM guides 7 and ball screw drive mechanisms 6 and 9 which can minimize volume without being restricted by stroke distance. However, rack and pinion drive mechanisms and belt conveyor drive mechanisms have limitations such as volume, speed, and stroke distance, but may be adopted as a workaround.

Since the driving force generating device adopts a small high speed reversible motor (8) 6000r / min and drives a ball screw drive mechanism having a stroke distance of 900m / m and a lead of 6m / m, the rise time takes 1.5 seconds, and thus requires a conventional extraction operation. It can be shorter than time.

Looking at the operation according to the above structural features are as follows.

As shown in FIG. 3, when the user operates the selection button, the cylindrical can product falling free from the ejection mechanism E passes through the passage door 10 through the funnel chute 11 and is in the standby catcher 5. When entering into the sensing means (sensor or limit switch) disposed at a predetermined position detects the entry and sends a signal to the lift control panel 15 to rotate the motor 8 forward. At this time, the catcher box 4 is raised by driving the ball screw drive mechanisms 6 and 9 condensed with the motor shaft, and the catcher 5 rotates with the product to reach the outlet 1 in an upright state. .

At this time, the ejection door 2 blocking the ejection opening 1 is pushed up along the guide 3 so that the user ejects the can product in an upright state with the ejection opening 1 open.

Then, when the sensing means arranged at a predetermined position detects this and sends a signal to the lift control panel, the motor 8 operates the ball screw drive mechanism in reverse rotation to lower the catcher 5. At this time, when the ball screw drive mechanism drives and descends, the projection part 12 enters the standby state while forming the same inclination angle as that of the chute 11, and the ejection door closes the ejection opening by its own weight.

As described above, the present invention improves the conventional lower drop discharging method to the upper ascending type and automates the opening and closing of the access door, so that the user can easily take out the can product in an upright state.
