Conventional techniques for the automatic shoe polishing associated with the present invention include a shoe polishing device of Utility Model Registration No. 181854, a structure of an automatic shoe polishing device of Utility Model Publication No. 2000-747, a shoe polishing apparatus of Patent Publication No. 2000-39565, Patent Publication No. 1998 For example, the shoe polisher of -82066.

In the above-described conventional shoe polisher, the shoe polish used is a liquid, so there is a problem that the gloss is not polished properly even when the shoe is polished. The shoe brush itself uses a simple round brush, so the shoe brush is in one direction when contacted with the shoe. The slanted contact resulted in not only the removal of foreign matter on the shoes, but also the lack of gloss.

In order to solve such a problem, Patent No. 414529 uses solid shoe polish and has a step and upper brush shape to allow forward and reverse rotation to be performed, and the upper brush contacts the shoe at an appropriate load by weight. We have developed an automatic shoe polish that allows you to wipe your shoes clean and glossy in a short time.

On the other hand, in the automatic shoe polish of Patent No. 414529, three bitumen supply parts are provided to supply the bitumen to the brush to clean the front part of the shoe and the brush to clean the side and the rear part, thereby supplying the bitumen in connection with the movement and rotation of the brush. It was intended to be described by the drawings as follows.

Such a conventional bitumen supply unit (apparatus) is controlled at the same time by the control unit (not shown), but the mechanical assembly state of each supply device and the driving characteristics of the motor 34 used in each supply device is slightly different As a result, there is a difference in the amount of bitumen supplied and consumed by each supply device. As a result, the bitumen time of the bitumen is not the same at each bitumen supplying part (30, 60), so the replacement time of the bitumen is changed. Not only is this cumbersome, but if it cannot be replaced in a timely manner, the shoe polish runs out and it becomes a factor that makes consumers dissatisfied with the performance of the automatic shoe polisher.

The present invention has been made in order to solve the above-mentioned conventional problems, the object of the present invention is to provide a bitumen by uniformly consumed by the bitumen supplied from a plurality of bitumen supply device installed in the interior of the automatic shoe polish to be uniformly consumed Improved structure that prevents complaints about the performance of automatic shoe polisher from consumers by enabling replacement of shoes at once and preventing shoeless operation when using shoe polish. To provide shoe polish supplies for automatic shoe polishing.

In order to achieve the above object, the present invention provides a shoe holder in which a solid shoe polish is embedded, a front plate attached to the front of the holder, and a solid shoe polish inserted into the shoe holder to push forward. And a pushing plate fixed to a screw attached to the motor, and a screw axially coupled to the motor, and a pushing plate fixed to an end of the push rod attached to the back of the holder, so that the push rod is the bitumen holder by the forward and reverse rotation of the motor. In the shoe polish supply device is to push the bitumen inside to the outside, the front plate of the holder is provided with a lid that is opened and closed in conjunction with the movement of the brush; The screw is formed at its rear end with an unthreaded extension, and the pushing plate is fitted to the extension at the rear end of the screw even if the pushing plate is separated from the screw while the screw rotates by the reverse rotation of the motor.

Even if the (37) is separated from the screw (35), the position holding means (100) is provided for pushing the pushing plate (37) to stay in its position while being fitted in the extension (35a) of the rear end of the screw (35). The position holding means (100) comprises an end plate (110) attached to the rear end of the guide bar (33a) for fixing the pushing plate (37) forward and backward to the fixing bracket (33), and the end plate ( The spring 120 is installed between the 110 and the pushing plate 37.

In the present invention, the bitumen supply device further includes two sensors (S1, S2) installed at the forward limit position and the reverse limit position of the pushing plate 37 to control the forward and reverse rotation of the motor 34, the forward limit The motor 34 is immediately stopped when a signal is detected at the sensor S1 at the position, and when the signal is detected at the sensor S2 at the reverse limit position, the motor 34 is driven for a further 10 seconds and then stopped. Programmed into a control unit (not shown).

In the figure, reference numeral 39 is an indicator plate attached to the side of the pushing plate 37 to indicate the forward limit position and the reverse limit position of the pushing plate 37 by the sensors S1 and S2.

The reason for extending the driving time of about 10 seconds even if a signal is detected by the sensor S2 at the reverse limit position in the present invention is that the sensors S1 and S2 are installed only on one side bitumen supplying device, so Considering the different assembly state and the driving characteristics of each drive motor is to ensure that the pushing plate 37 installed in the three bitumen feeder is retracted to the exact same initial position.

In addition, in the present invention, the spring 120 is of a compression coil type, which is installed on the same axis as the extension part 35a of the rear end of the screw 35 so that the extension part 35a of the pushing plate 37 at the time of reversing Located inside the spring 120 to rotate, at this time, the spring 120 acts to push the pushing plate 37 forward while being pressed in contact with the pushing plate 37, the pushing plate 37 is a screw Since it is out of the male screw part of (35), it will hold in place.

On the other hand, in the present invention, the front plate 32 is detachably provided with a detachment prevention device 130 for preventing the solid shoe polish (P) fitted to the shoe polish holder 32 to be separated from the front, which is the front The plate 32 is formed in the form of a clip detachable with its own elastic force, the front plate 32 is formed with a fitting groove (32a) is fitted in the horizontal direction in which the release prevention device 130 of the clip form.

The bitumen supplying process and the bitumen replacement process in the bitumen supply device of the present invention configured as described above will be described.

Figure 6 is a cross-sectional view showing a state at the time of detecting the shoe is exhausted in the shoe at the forward limit position in the shoe polish supply device of the present invention, Figure 7 is a pushing plate in the shoe polish supply device of the present invention in the reverse limit position It is sectional drawing which shows the state detected by the sensor.

First, the automatic shoe polisher of the shoe polish supply device of the present invention, when a user puts a coin (for example, 500 won coin) into a coin inlet (not shown) and puts a foot on the shoe holder 20, the shoe holder ( 20) The sensor (not shown) at the bottom detects this and starts the operation and operates for a set time (about 2 to 3 minutes). As the side brush 40 rotates, the lower movable body 50 moves forward and the shoes After removing the dirt or dust on the shoe placed on the cradle 20, the lid 38 of the front shoe polish supply unit 30 is opened, and the side brush 40 is rotated in contact with the shoe with the shoe polish so as to rotate backwards. The upper movable body 80 is moved forward and backward by the movement of the lower movable body 50 at a predetermined distance from the lower movable body 50, and the upper brush 70 on one side rotates to move soil and dust on the upper portion of the shoe. After removing the bite bitumen Would be in contact to the shoe dakge the shoe, the upper brush 70 is moved to the center of the other side to give a gloss to before, the gloss me oral and backward motion.

Shoe wiping operation as described above is to be made repeatedly by the input of coins, whereby the solid shoe polish (P) of the shoe polish supply device, that is, the front shoe polish supply unit 30 and the rear shoe polish supply unit 60 on both sides of the motor (34) The screw 35 is rotated forward by the intermittent driving and the push rod 36 of the pushing plate 37 is gradually pushed forward and buried in the brush, and is consumed as shown in FIG. 6. When the sensor S1 detects that the bitumen is exhausted, the control unit (not shown) sends a reverse driving signal to the motor 34 so that the screw 35 reversely rotates, thereby pushing the plate 35 screwed with the screw 35. When 37 is reversed, the sensor S2 at the reverse limit position detects the signal, and sends a signal to the controller (not shown), and the controller controls the number of the signals. The motor 34 continues the reverse rotation for about 10 seconds without sending a stop signal to the motor 34 immediately after the renewal.

On the other hand, the screw 35 is axially coupled with the drive motor 34 because the pushing plate 37 is in the state of being pushed out of the male screw portion of the screw 35 and fitted to the extension portion 35a where no thread is formed in the reverse limit position. Is rotated, the pushing plate 37 is maintained in place without moving backward or forward, wherein the spring 120 of the position holding means 100 provided at the rear of the pushing plate 37 is the pushing plate 37 Since the state is pushing forward), the position of the pushing plate 37 is still to maintain the original initial position.

As such, the present invention, when controlling a plurality of bitumen supply device installed in each of three locations in one control unit, pushing the bitumen (P) even if the mechanical assembly state of each bitumen supply device and the driving characteristics of the motor is different Since the initial positions of the plates 37 can all be set to be the same, the consumption of bitumen P can be kept constant, which causes the same point of exhaustion of the bitumen P embedded in each bitumen supply device. The shoe polish can be replaced all at once, making the maintenance of the automatic shoe polish more convenient.

In addition, the shoe polish supply device of the present invention can control the amount of bitumen supplied from the plurality of bitumen feeder to be exactly matched by using a general motor rather than an expensive servo motor, thereby reducing the manufacturing cost of the automatic shoe polish.

As described above, the present invention allows each part of the shoe to be supplied with the same amount of the shoe polish supplied to the brush for the front part of the shoe and the shoe polish supplied to the brush for the left and right sides of the shoe in the automatic shoe polishing. As the bitumen supply is consumed by the bitumen supplying device for the bitumen supplying device, the bitumen time of the bitumen is the same, so that it is possible to replace the bitumen at a time, which makes it easy for the operator (administrator) to maintain the automatic shoe polish. However, the consumer (user) has a useful effect of solving the problem of the shoe polish falling off when the shoe is used to polish the shoe.
