The carrier 4 is a disc reproducing apparatus 3,3 'of an auto changer through a vertical transfer motor, a reduction gear, a drive shaft, a pulley 5, 5', and a timing belt 6 wound around the pulley. It moves up and down vertically between the magazine and the magazine 2, and both ends of the carrier are fixedly connected to the timing belt 6 disposed at both sides of the auto changer, thereby moving up and down by rotation of the timing belt.

The auto changer configured as described above takes the disc out of the magazine 2 and moves it to the disc reproducing apparatuses 3 and 3 'while the carrier 4 moves up and down by an up-and-down conveying motor (not shown) for playback, or playback is performed. The finished disk is moved back to the magazine and stored in the space formed in the magazine.

However, the carrier has a constant load, and thus a motor for transporting the carrier in the vertical direction is required to have a relatively large capacity, especially as the carrier receives a larger load when the carrier moves upward.

In addition, it was difficult for the carrier to accurately maintain a predetermined position on the Z axis due to the load.

Accordingly, the present invention is to overcome the above-mentioned conventional problems, an object of the present invention is to give a minimum load to the Z-axis feed motor of the carrier when the carrier of the auto changer moves in the Z-axis direction, Z-axis of the carrier To provide an optimum load to the vertical transfer motor of the auto changer carrier to maintain accuracy in positioning.

Another object of the present invention is to vertically transfer the motor of the auto changer carrier so that the carrier of the auto changer moves in the Z-axis to give a minimum load to the Z-axis feed motor of the carrier and maintain the accuracy in positioning of the carrier. To provide a balancer that is used to give an optimal load to the system.

As an example of a method for applying an optimum load to the vertical movement motor of the auto changer carrier for achieving the object of the present invention, a pair of magazines for accommodating a compact disc, a disk reproducing apparatus, and a vertical rotation motor Both ends are fixedly connected to a timing belt of an auto changer carrier motor which includes a compact disc ejection and transfer carrier which moves between the disc reproducing apparatus and a magazine vertically in a vertical direction by rotation of the timing belt. A method of applying an optimum load is characterized in that a balancer opposing the carrier is mounted on each of the pair of timing belts to which the carrier is fixedly connected.

Further, according to the present invention, the total load of the pair of balancers is set to be smaller than the load of the carrier, and the load difference between the carrier and the pair of balancers is set to be smaller than the frictional load of the carrier.

Furthermore, according to the present invention, both ends are fixedly connected to a magazine for accommodating a compact disc, and a pair of timing belts rotated by a disc reproducing apparatus and a vertically moving feed motor, so as to achieve rotation of the timing belt. Provided is a balancer for use in a method of applying an optimum load to a carrier up-and-down transfer motor of an auto changer including a compact disc take-out and transfer carrier which moves up and down vertically between the disc reproducing apparatus and a magazine.

The balancer according to the present invention includes a quadrangular body, a plurality of weight plates attached to the body with screws, and a plurality of rollers installed at corner portions of the body, and a pair of timing belts to which the carrier is fixedly connected. It is mounted so as to face the carrier.

Also preferably, the balancer may adjust the weight by adding or subtracting the plurality of weight plates.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the same parts as in the prior art will be indicated by the same reference numerals.

Referring to FIG. 2, the overall configuration of the auto changer of the present invention is shown.

The magazine 2 for accommodating the disk 10 is mounted on both sides of the main body 1, and in general, four magazines are mounted on both sides, and each magazine contains 45 discs.

At the bottom of the magazine 2, disc reproducing apparatuses 3 and 3 'are mounted, and a carrier 4 for transferring a disc housed in the magazine to a disc reproducing apparatus or a disc which has been reproduced in a disc reproducing apparatus to a magazine 4 ) Is centered.

The carrier 4 is a disc reproducing apparatus 3,3 'of an auto changer through a vertical transfer motor, a reduction gear, a drive shaft, a pulley 5, 5', and a timing belt 6 wound around the pulley. It moves up and down vertically between the magazine and the magazine 2, and both ends of the carrier are fixedly connected to the timing belt 6 disposed at both sides of the auto changer, thereby moving up and down by rotation of the timing belt.

The auto changer configured as described above takes the disc out of the magazine 2 and moves it to the disc reproducing apparatuses 3 and 3 'while the carrier 4 moves up and down by an up-and-down conveying motor (not shown) for playback, or playback is performed. The finished disk is moved back to the magazine and stored in the space formed in the magazine.

In addition, in order to maintain the accuracy in positioning the Z axis of the carrier 4 and to give an optimum load to the vertically moving feed motor of the auto changer carrier, the timing belt 6 has a balancer 20 according to the present invention. Both sides of (4) are connected via fixing brackets 11 in a direction opposite to the direction in which they are connected.

Accordingly, the balancer 20 moves in a direction opposite to the carrier 4 in the vertical direction along the guide rail 12 as the timing belt 6 rotates.

The principle of the method according to the invention will now be described with reference to FIG.

The carrier 4 includes a vertical transfer motor 7, a reduction gear 8, a drive shaft 9, a drive pulley 5 connected to the drive shaft, a driven pulley 5 ′ opposite thereto, and the pulley 5. It moves up and down vertically through the timing belt 6 wound around 5 ').

In general, since the carrier 4 has a constant load and moves in the vertical direction, a relatively large load is applied to the up-and-down transfer motor 7 of the carrier, especially when moving upward.

Therefore, in order to apply an optimal load to the vertical transfer motor 7 of the auto changer carrier so that the load is applied to the vertical transfer motor of the carrier to a minimum and maintain its accuracy when positioning the carrier 4 in the Z-axis position. According to the timing belt 6, a pair of balancers 20 are connected in a direction opposite to a direction in which both sides of the carrier 4 are connected.

The load of the balancer 20 is set slightly smaller than the load of the carrier 4 and is adjustable as will be described later.

Therefore, when the balancer is installed, the load received by the motor is, for example, the load of the carrier 4 is 1.7 kgf, and the total load of both balancers 20 is 1.4 kgf. If the load is 0.7kgf,

When moving upward: 1 kgf = Carrier Load (1.7kgf)-Balancer Load (1.4kgf) + Friction Load (0.7kgf)

Downward movement: 0.4 kgf = Friction load (0.7kgf)-Carrier load (1.7kgf)-Balancer load (1.4kgf)

As described above, the total load of the pair of balancers 20 is set smaller than the load of the carrier 4, and the difference in load between the carrier 4 and the pair of balancers 20 is the friction of the carrier 4. It is desirable to set it smaller than the load.

Therefore, when installing the balancer according to the present invention, since the friction load (0.7kgf) is greater than the load difference between the carrier and the balancer (0.3kgf), the carrier can be moved upward to position and maintain its position accurately and the large power of the motor This is not necessary, but when the balancer is not installed as in the prior art, a large power of the motor is required.

The balancer used in the method according to the invention will now be described with reference to FIGS. 4 and 5, respectively, which are shown in plan and side views, respectively.

Referring to FIG. 4, the balancer 20 includes a rectangular body 21, a plurality of weight plates 23 attached by screws 22 in the body, and a plurality of balance plates installed at corner portions of the body. It consists of the roller 24.

Referring to FIG. 5, the body 21 is composed of a base surface 21a on which the plurality of weight plates 23 are mounted, and a side surface 21b perpendicular to the base surface.

On the other hand, the balancer 20 is because the weight plate 23 is composed of a plurality as shown, it is possible to adjust the load by adding or subtracting it.

Further, as mentioned, the pair of balancers 20 has a total load less than the load of the carrier 4, and the load difference between the carrier 4 and the pair of balancers 20 is the carrier 4. It is preferable to be set to be smaller than the friction load during the vertical movement of.

With the above configuration, the balancer according to the present invention operates as follows.

The balancer 20 is connected to the timing belt 6 via a fixing bracket 11 in a direction opposite to a direction in which both sides of the carrier 4 are connected. Accordingly, the balancer 20 moves up and down the transfer motor. (7), the reduction gear (8), the drive shaft (9), the drive pulley (5) connected to the drive shaft, the driven pulley (5 ') and the timing belt wound around the pulley (5, 5') ( The roller 24 of the balancer is guided to the guide rail 12 through 6) and vertically moves up and down with the carrier 4 along the guide rail 12.
