It is. In this state, when the slider 10 is moved to an appropriate position using the operation lever 83, and the air valve 28 is opened, the pipe members 20 to 24 are moved downward by their own weight as shown in FIG. Elongate When the product adheres to the lower end of the fifth pipe member 24 by the suction force of the vacuum suction unit 30, the pipe members 20 to 24 are contracted again as shown in FIG. 1. In this state, the slider 10 is moved, and then the air valve 28 is opened to discharge the product out of the main body 1.

However, in the goods extraction apparatus of FIGS. 1 and 2, when the air valve 28 is opened to discharge goods, the goods are released from the lower end of the fifth pipe member 24 and the pipe members 20 to 20. Since 24) is elongated downward, there is a problem in that operation and use are inconvenient. In addition, since the exhaust pressure generated in the vacuum suction unit 30 adsorbs the product through the pipe members 20 to 24, there is a problem in that the exhaust pressure is largely lost and noise is generated.

On the other hand, Figure 3 is an illustration of the structure of the suction-type product take-out device introduced in the Utility Model Registration No. 20-0234088, the operating port 23 for moving along the fixed bar (7) is installed inside the main body of the amusement machine , The lower end of the operating port 23 is made of a structure in which the operating rod 25 and the suction port (9) is connected. The actuating rod 25 is raised or lowered by the wire 22 passing through the actuating tool 23, and the wire 22 is wound on the wire drum 18 through the roller 20. The suction port 9 is connected to a compressor (not shown) through the vacuum hose 30.

However, the product taking out device of FIG. 3 is not only structurally impaired in movement by the vacuum hose 30 installed in the fixing bar 7, but also on the fixing bar 7. There is a problem that the moving range of the operating tool 23 is limited. In addition, if a product is attached to the suction port 9, there is a risk that an accident may occur in which the motor is burned while the compressor is overloaded.

In addition, even if the configuration is essential to practice the present invention is introduced in the prior art including Figures 1 to 3, or a detailed description of matters that can be easily implemented by those skilled in the art from the known art will be omitted.

As shown in FIG. 4, the suction type product taking out device according to the present invention includes a product storage case (not shown), a guide rail 10 installed inside the upper end of the product storage case, and the guide rail 10. It comprises a sliding unit 20 to move along, and the product withdrawing means 30 to move up and down in the sliding unit (20).

First, the product storage case is, for example, similar to a general entertainment vending machine, a rectangular box shape in which various goods G are provided therein, and at least one surface is provided with a transparent window so that the user can see the inside. . The product storage case is provided with an operation handle that allows the user to operate the sliding unit 20 and the product withdrawing means 30, a coin slot for inserting coins or bills, and a product outlet. A turntable may be installed to rotate the bottom surface such that the goods G are rearranged.

Next, the guide rail 10 includes a pair of fixed rails 11a and 11b installed in the X-axis direction and a pair of moving rails 12a and 12b installed in the Y-axis direction. The fixing rails 11a and 11b are fixedly installed side by side at opposite corner portions of the product storage case. The moving rails 12a and 12b are installed side by side with a slight gap between the fixed rails 11a and 11b and move along the fixed rails 11a and 11b in the X-axis direction.

The fixed rails 11a and 11b are provided with rail blocks 13 supporting both ends of the movable rails 12a and 12b, respectively. The driving pulley 14 and the driven pulley 15 are installed at both ends of the first fixed rail 10a, and the rail block 13 is pulled between the driving pulley 14 and the driven pulley 15. The towing wire 16 which moves by moving is provided.

Cable support beams 17 are arranged side by side on one side of the fixed rail 10a and the movable rail 20b. The cable support beam 17 accommodates and supports an electric wire cable (not shown) for supplying power to the sliding unit 20 and the product withdrawing means 30. The cable support beam 17 slides with the movable rails 12a and 12b. Irrespective of the movement position of the unit 20, the electric wire cable functions to support the cable not to fall down.

Next, the sliding unit 20 is installed between both moving rails 12a and 12b to move in the Y-axis direction along the moving rails 12a and 12b. 5 and 6, one side of the sliding unit 20 is provided with a bush bearing 21, the other side is provided with a drive roller 22 and the pressure roller 23. In addition, a wire drum 24 is installed inside the sliding unit 20.

A first moving rail 12a is slidably penetrated through the bush bearing 21, and a second moving rail 12b is supported between the driving roller 22 and the pressure roller 23. Thus, the sliding unit 20 moves along the moving rails 12a and 12b by the driving force of the driving roller 22. The wire drum 24 serves to elevate the product withdrawing means 30.

The product withdrawing means 30 includes a plurality of lifting pipes 31 installed at a lower end of the sliding unit 20, an exhaust pump 32 installed at a lower end of the lifting pipe 31, and the sliding unit 20. And a lifting wire 33 connecting between the exhaust pump 32 and a suction cup 34 coupled to the lower end of the exhaust pump 32.

First, the elevating pipe 31 is composed of a plurality of pipes having different diameters so as to be accommodated sequentially, and is coupled to extend or contract in the Z-axis direction at the lower end of the sliding unit 20. 5 and 6 illustrate an exemplary embodiment of the present invention, in which the elevating pipes 31 are formed of four, that is, first to fourth pipes 31a to 31d. The upper end of the first pipe 31a having the largest diameter is fixed to the bottom of the sliding unit 20, and the remaining second to fourth pipes 31b to 31d are sequentially in the first pipe 31a. It is stored.

In addition, stopper movement slots 311 are formed at one side of each of the first to third pipes 31a to 31c in the longitudinal direction, and the movement is formed at the upper ends of the second to fourth pipes 31b to 31d, respectively. A stopper 312 moving along the slot 311 protrudes. Thus, the stopper 312 of the second pipe 31b is inserted into the moving slot 311 of the first pipe 31a, and the stopper of the third pipe 31c is inserted into the moving slot 311 of the second pipe 31b. 312 is inserted. Thus, the lifting pipe 31 is contracted or extended in the Z-axis direction without departing from each other. FIG. 5 shows a state in which the lifting pipe 31 is contracted, and FIG. 6 shows an extended state.

The exhaust pump 32 is coupled to the lower end of the fourth pipe 31d. The exhaust pump 32 is preferably embedded in the pump housing 321 so as to be easy to replace and repair. In addition, the pump housing 321 is made of a porous metal plate so as to effectively dissipate and cool the heat generated in the exhaust pump 32, and preferably cylindrical.

The lifting wire 33 is connected between the sliding unit 20 and the exhaust pump 32, one end is wound on the wire drum 24, the other end is the pump housing 321 Is connected to. Thus, when the wire drum 24 is wound around the lifting wire 33, the exhaust pump 32 is raised, and when the lifting wire 33 is released, the exhaust pump 32 is lowered. When the exhaust pump 32 is raised, the lifting pipe 31 is reduced, and when the exhaust pump 32 is lowered, the lifting pipe 31 is extended. The electric wire for supplying power to the exhaust pump 32 is composed of a coil-type electric wire 322 wound around the elevating pipe 31 so as not to interfere with the stretching operation of the elevating pipe 31.

The suction cup 34 has a hemispherical cup shape coupled to the lower end of the exhaust pump 32 and is suspended upside down such that the opening faces the bottom surface of the product storage case. Thus, the adsorption cup 34 adsorbs the merchandise G listed at the bottom of the merchandise storage case by using the adsorption force of the exhaust pump 32.

The adsorption cup 34 preferably has a dual structure of a relatively large outer adsorption cup 34a and an inner adsorption cup 34b provided therein. The outer adsorption cup 34a is used to adsorb a large diameter product G, and the inner adsorption cup 34b is used to adsorb a relatively small diameter product G.

The outer suction cup 34a is preferably formed such that the edge 341 of the opening is obliquely diagonally formed. As shown in FIG. 7A, when the edge 341 of the opening of the external adsorption cup 34c is horizontally cut, between the two or more products G when the external adsorption cup 34c is lowered. There is a possibility that it is placed upright, and in this case, the air may be sucked into the space between the two goods G, and thus the goods G may not be adsorbed.

However, in the external adsorption cup 34a of the present invention, since the edge 341 is formed obliquely at an oblique line, the external adsorption cup 34a has little possibility of being placed straight between two or more products G. That is, when the external adsorption cup 34a is lowered, as shown in FIG. 7 (B), since any one of the edges 341 touches the product G first and loses balance and slides at an angle, the external adsorption is performed. The cup 34a naturally rests on one of the goods G.

Vent holes 342 may be formed in the inner suction cup 34b. The vent 342 reduces the load applied to the exhaust pump 32 by introducing a small amount of air into the inner suction cup 34b when the product G is adsorbed to the inner suction cup 34b. Giving functions. This is because the product G adsorbed to the inner adsorption cup 34b can be adsorbed even with a relatively weak adsorption force. The inner suction cup 34b may be detachably installed at the lower end of the exhaust pump 32 so that the inner suction cup 34b may be replaced with a different diameter as necessary.

In the present invention, the lifting pipe 31 functions to prevent rocking and rotation of the exhaust pump 32. If the exhaust pump 32 is suspended only in the lifting wire 33 without the lifting pipe 31, the exhaust pump 32 is severely rocked left and right when the sliding unit 20 moves. Therefore, the user has to wait until the fluctuation of the exhaust pump 32 is stopped in order to place the suction cup 34 on the product G desired by the user.

In addition, when the exhaust pump 32 operates (particularly in the case of using an AC motor), the lifting force 33 is twisted while the rotational force is generated. However, the product taking out device according to the present invention can prevent the exhaust pump 32 from swinging from side to side or rotates because the lifting pipe 31 holds the exhaust pump 32. 34) can be quickly placed on the desired product (G).

On the other hand, the sliding unit 20 is provided with a lift control sensor (25a, 25b) for detecting the upper limit and the lower limit of the exhaust pump 32 to control the drive of the wire drum (24). The first control sensor 25a senses the impact of the exhaust pump 32 when the upper end of the fourth pipe 31d reaches the lower end of the sliding unit 20 to drive the wire drum 24. Stops. To this end, contact sensing members 251 and 252 corresponding to each other are provided at the lower end of the sliding unit 20 at the upper end of the fourth pipe 31d.

Next, the second control sensor 25b measures the tension of the lifting wire 33. That is, when the exhaust pump 32 descends and the suction cup 34 rests on the product G, the tension of the lifting wire 33 is loosely relaxed, and the second control sensor 25b detects this. To stop the drive of the wire drum 24. To this end, a tension sensing member 253 is installed in the second control sensor 25b. The lifting wire 33 passes through both the contact sensing members 251 and 252 and the tension sensing member 253.

4 to 7, the driving pulley 14, the driving roller 22, the wire drum 24 and the exhaust pump 32 are respectively provided with a motor for driving them, the motor not shown separately in each drawing Did. And the operation method of the suction type product taking out device according to the present invention is similar to the driving method of a conventional entertainment product taking out device.

In addition, any kind of merchandise G that can be sold through the suction-type product withdrawing apparatus according to the present invention may be any product as long as it can be adsorbed by the suction cup 34, but the overall shape is preferably spherical. Therefore, in the case of a shape that is not easily adsorbed by the adsorption cup 34 such as a small candy or a ring, it is preferable to store these products in a spherical plastic container and store them in a product storage case.
