Referring to the operation of the automatic roll toilet paper discharge device of the present invention configured as described above are as follows.

First, in order to mount the roll 2 on which the toilet paper is wound on the discharge device, the cover member 30 is opened and closed on the upper part of the case 10. Since the drive motor 40 is provided on the inner upper part of the case 10, and the mounting rod 50 is provided on the rotation shaft 42 of the drive motor 40, the scroll rod 2 is attached to the mounting rod 50. Insert it. In this case, since the mounting rod 50 is rotated in one direction only through the normal one-way clutch 54 to the rotation shaft 42 and coupled to the other direction, the mounting rod 50 is driven by the driving motor 40. 50 and the direction in which the toilet paper is released in the roll (2) to be rotated to match the mounting.

When the scroll 2 is completely pushed while the scroll 2 is inserted into the mounting rod 50, the side of the scroll 2 naturally pushes the wheat plate 94. Thus, as shown in FIGS. 8 and 9, the plate 94 is slidably coupled to the stationary block 14 through the sliding shaft 92 while being rotatable, and the sliding shaft 92 and the stationary block ( 14, while the compression spring 96 is provided between the sliding shaft 92 on the opposite side of the mill 94, the movable block 90 is provided, so that the compression spring as the scroll 2 pushes the mill 94 As the 96 is compressed, the sliding shaft 92 slides, and the movable block 90 is spaced apart from the fixed block 14, and formed on one side of the movable block 92 according to the movement of the movable block 90. The fixed shaft 98 is separated from the coupling hole 72 of the rotating plate 70.

The rotating plate 70 is in a free state without restraint, and the rotating plate 70 is fixed to the lever shaft 60, while the lever shaft 60 is supported by the elastic spring 64, the elastic spring thereof As the lever shaft 60 is rotated upward by 64, the support lever 62 formed on the lever shaft 60 is rotated upward to come into close contact with the surface of the roll 2 (see FIGS. 4 and 10). . At the same time, the movable block 90 and the sealing plate 94 try to return to the original position by the restoring force of the compression spring 96 provided on the sliding shaft 92. The movable block 90 has a fixed shaft 98 at the same time. ), And the coupling hole 72 into which the fixed shaft 98 is inserted is deviated from the fixed shaft 98 by the rotation of the rotating plate 70, so that the movable block 90 of the fixed shaft 98 While the end is returned until it comes in close contact with the rotating plate 70, the fixed shaft 98 continuously maintains the state of pressing the rotating plate 70 by the elastic force of the compression spring 96.

Here, before describing the following operation, first, an operation in which the amount of toilet paper remaining in the scroll 2 is detected by using the toilet paper from the scroll 2 will be described. When the toilet paper is gradually reduced in the scroll 2, the scroll ( The outer diameter of 2) is reduced. Since the support lever 62 presses the surface of the scroll 2 by the elastic spring 64, the support lever 62 also decreases as the outer diameter of the scroll 2 decreases. It naturally rises and rotates, and thus, the rotary plate 70 connected to the support lever 62 and the lever shaft 60 also rises and rotates.

When the toilet paper is not used, the rotating plate 70 blocks all of the phase angle sensor 80 (three optical sensors) so that the electronic control module 4 supplies the remaining amount of toilet paper to the liquid crystal display 22. Although 75% to 100% is displayed, when the toilet paper is continuously used, the rotating plate 70 is rotated upward, and the phase angle sensor 80 is excessively sequentially one by one. Then, the light irradiated from the light emitting element unit 82 of the phase angle sensor 80 reaches the corresponding light receiving element unit 84, and when the arrival signal is applied to the electronic control module 4, the electronic control module 4 is applied. ) Confirms (sums) the number of signals applied from the phase angle sensor 80 and displays the remaining amount of toilet paper on the liquid crystal display 22 at a value corresponding to the number of signals.

After all the toilet paper of the scroll 2 is exhausted, it is an operation for replacing with a new scroll 2 according to the indication of the remaining amount of toilet paper remaining on the liquid crystal display unit 22, from the mounting rod 50 to the scroll 2 After removing the support lever 62, the lever shaft 60 and the rotating plate 70 of the support lever 62 is rotated, the coupling hole 72 formed in the rotating plate 70 of the lever shaft The support lever 62 is rotated to the initial position because the support lever 62 is formed at a position coinciding with the fixed shaft 98 at the point where the support lever 62 is rotated to the initial position which does not contact the scroll 2. When the fixed shaft 98 of the movable block 90 coincides with the coupling hole 72 of the rotating plate 70, the movable block 90 moves in accordance with the movement of the movable block 90 due to the elasticity of the compression spring 96. ), The fixed shaft 98 is inserted into the coupling hole 72 so that the rotation of the rotating plate 70 and the lever shaft 6 and the support lever 62 are first performed. Value is to be bound.

Again, after mounting the reel (2) to the mounting rod 50 will be described the operation process until the toilet paper used to pull out.

First, as described above, select the desired number of discharge volumes by operating the selection button 24 on the operation panel 20 with the scroll 2 mounted on the mounting rod 50, and then press the start button. The driving motor 40 is rotated by the control of) and the roll 2 is rotated so that the toilet paper is released from the roll 2. Then, the toilet paper is continuously released as shown in Figure 4, the center of the winding means 100, that is, between the long rod 124 of the moving bar 120 and extends to the bottom of the case 10, toilet paper is the case ( 10) the light emitting device unit 242 and the light receiving device unit 244 of the loosening detection sensor 240 provided on the floor is cut off, the electronic control module 4 detects the signal of the toilet paper is determined to be sufficiently loose By blocking the current to the drive motor 40 to stop the rotation of the scroll (2).

Next, the rotation and the retraction means 130 is operated by the control of the electronic control module 4, as can be seen in the accompanying drawings 11, 12, 13 and 22, the motor of the rotation and retraction means 130 When 132 is activated, driven pulley 146 connected to drive pulley 134 of motor 312 by belt 136 rotates. Since the driven pulley 146 is formed on the drive shaft 140, the drive shaft 140 is rotatably installed on the installation block 16 on the case 10 side, so that the rotational force of the driven pulley 140 is increased. It is transmitted to the drive shaft 140.

Meanwhile, the support shaft 112 of the rotation bar 110 is rotatably coupled to the drive shaft 140, and a first pulley 142 is formed at an end of the drive shaft 140, and the first pulley 142 is provided. ) Is connected to the second pulley 152 formed on the spiral bar 150 as a belt 144, the spiral bar 150 is rotatably installed on the support 112 of the rotating bar 110 Since it is screwed to the support base 122 of the moving bar 120, the spiral bar 152 is driven by the belt 144 to rotate according to the rotation of the drive shaft 140 and the first pulley 142, thereby moving bar The support 122 of the 120 moves to the support 112 side of the rotation bar 110 to be in close contact. Strictly in close contact with the side of the first, second pulleys (142, 152).

This state is described as an operation process in which the moving bar 120 is in close contact with the rotation bar 110 side, but is exactly the first state that the toilet paper is first discharged to the operator and then returned to its original position.

In this state, the contact plate 166 provided on the support base 122 of the movable bar 120 presses the limit switch 164 on the case 10 side, and the operation signal of the limit switch 164 is applied. Is applied to the electronic control module 4, the electronic control module 4 stops the driving of the motor 132 and starts the operation for winding the toilet paper. That is, according to the signal from the limit switch 164, a current is applied to the solenoid actuator 160 to draw the spool 162 thereof, and a current is also applied to the motor 132 to drive it. At this time, the spool 162 is separated from the groove 116 formed in the support 112 of the rotation bar 110, the rotation bar 110 is free, the rotation bar 110 of the support bar 112 is described above As described above, the driving shaft 140 is rotatably coupled and the moving shaft 120 is in close contact with the rotating shaft 110 so that the moving shaft 150 no longer moves toward the rotating shaft 110 even when the spiral rod 150 rotates. It is not able to do it. Therefore, the drive shaft 140 and the first pulley 142 of the front end of the motor 132 rotates, and the second pulley 152 connected to the belt 144 on the first pulley 142 rotates. The vane 150 cannot rotate. Therefore, the rotational force to rotate the spiral bar 150 is transmitted to the rotating bar 110 as it is through the moving bar 120, the rotating bar 110 and the moving bar 120 is integrally rotated, the rotating bar ( According to the integral rotation of the 110 and the moving bar 120, toilet paper that has been stretched between the long bars 124 of the moving bar 120 is wound on the moving bar 120.

As the toilet paper is wound in this manner, the contact plate 166 provided on the support 122 of the movable bar 120 operates the limit switch 164 at every rotation period of the rotary bar 110. The electronic control module 4 determines the number of windings of the toilet paper by adding the operation signal of the limit switch 164 each time, and confirms the number of the number of choices input by the operator.

If the total number of the limit switch 164 operation signals and the number of selections input by the operator coincide, the electronic control module 4 turns off the solenoid actuator 160 to advance its spool 162, and the spool 162 rotates. At the last rotation of the bar 110 is inserted in accordance with the groove 116 formed in the support 112 of the rotary bar 110 to restrain the rotating bar 110 in a horizontal state.

As such, when the rotary bar 110 maintains the horizontal state, the toilet paper T is kept connected to the winding means 100 from the roll 2 in a state as shown in FIG. 22. At this time, the cutting means 170 is operated in the electronic control module 4, as shown in FIGS. 14, 15, and 23, the motor 180 in the state where the movable cutter 174 is first opened. Driving the rotating shaft 184 through the reduction gear 182 of the motor 180 rotates the movable cutter 174. At this time, since the fixed cutter 172 is fixed to the fixed block 18 through the screw 176, the movable cutter 174 is rotated to the fixed cutter 172 side to cut the ileum (T).

When the movable cutter 174 rotates as described above, the contact of the sensor 190 is turned off by the cam profile 192 formed on the movable cutter 174, and the operation signal thereof is sensed by the electronic control module 4. By rotating the motor 180 in reverse, the movable cutter 172 is opened to the initial position. In this case, when the movable cutter 172 is completely opened, the sensor 190 is contact-on-operated by the cam profile 192, and the electronic control module 4 detects this to stop the motor 180.

Next, as shown in Figure 16, 17, 18 and 23, after cutting the toilet paper (T) by the above-described operation, the end of the cut toilet paper (T) is on the upper surface of the toilet paper wound on the winding means (100) Put on. It presses the toilet paper is put on to operate the push lever 200 to facilitate the discharge. That is, the electronic control module 4 stops driving the motor 180 after the return of the movable cutter 174, operates the actuator 202 of the push lever 200, and according to the operation of the actuator 202, the actuator ( The first link 206 on the side 202 rotates. Then, the second link 206a connected to the first link 206 as the connection link 204 is rotated so that the push lever 200 is rotated downward to press the toilet paper.

After pressing the toilet paper with the pressing lever 200 in this way, by rotating and advancing means 130 is discharged toilet paper wound on the winding means (100). That is, when the electronic control module 4 operates the motor 132 in one direction, the drive shaft 140 rotates by the driven pulley 146 connected to the belt 136 to the drive pulley 134 of the motor 132, The first pulley 142 formed at the end of the drive shaft 140 rotates, and the spiral rod 150 rotates by driving the second pulley 152 which is driven and connected to the first pulley 142 by the belt 144. do. At this time, the rotation bar 110 is fixed to its support 112 in a horizontal state by the spool 162 of the solenoid actuator 160, the rotation bar 110 and the moving bar 120 does not rotate itself, Only the spiral rod 150 will rotate. As the spiral rod 150 rotates as described above, the spiral rod 150 is screwed to the support 122 of the movable bar 120, and the long rod 124 formed on the support 122 is the rotary shaft 110. Since the sliding shaft is coupled to the long shaft 112, the moving bar 120 slides toward the outlet 12 side of the case 10 in accordance with the rotation of the spiral rod 150 to discharge toilet paper as shown in FIG. The operator may use the toilet paper discharged as described above.

According to the present invention, when the press rollers 250 and 252 are provided on the outlet 12 side (see attached drawings 25 and 26), the movable bar 120 and the toilet paper wound thereon are discharge outlets 12 In the process of moving to the side) the motor 254 is driven by the electronic control module 4, the lower compression roller 252 is rotated and the elastic contact with the lower compression roller 252 by the elastic spring 258 When the upper compression roller 250 is rotated, toilet paper is moved to reach the compression rollers 250 and 252 to pass between the compression rollers 250 and 252, the elastic spring 258 in the process of passing through By the elasticity of the.

Again, after the discharge of the toilet paper, the motor 132 is rotated in the opposite direction, the moving bar 120 is moved to the rotation bar 110 by the opposite rotation of the spiral bar 150 accordingly, at the end of the movement, As described above, the moving bar 120 is in close contact with the rotating bar 110, and the contact plate 166 provided on the support base 122 of the moving bar 120 is the limit switch on the case 10 side. Pressing 164, the electronic control module 4 stops the driving of the motor 132 according to the operation signal of the limit switch 164 to prepare for the operation for winding the next toilet paper.

Next, the operation process of opening and closing the opening and closing door when the opening and closing door 210 is provided on the outlet 12 side according to the present invention, as shown in the accompanying drawings 19, 20, and 21, the electronic control module (4) When the actuator 214 rotates in the closing direction, the lever member 220 formed on the shaft 218 of the reducer 216 is pivoted up and down, and the opening and closing door 210 of the opening and closing door 210 has a lever member. Since it is slidably coupled to the long hole 222 of the 220, the moving shaft 224 moves upward in the long hole 222 in accordance with the rise of the lever member 220 to raise the opening and closing door 210 to the case The outlet 12 of the (10) side is blocked. In the state in which the opening and closing door 210 is raised as described above, the closing detection switch 226 is operated by the lever member 220 so that the electronic control module 4 stops the driving of the actuator 214. Since the first resilient member 234 is elastically inserted into the groove 230 on one side of the grooves 230 and 232 formed on both sides, the opening and closing door 210 may be continuously maintained.

When opening the outlet 12 by lowering the opening and closing door 210 to use the toilet paper, and to operate the actuator 214 in the opposite direction, the opening and closing door 210 is lowered in the reverse order of the above operation. At the end of the lowering, the opening detection switch 228 is operated by the lever member 220 so that the electronic control module 4 stops driving the actuator 214. Then, the second elastic member 234 is elastically inserted into the groove 232 of one side of the grooves 230 and 232 formed on both sides of the opening and closing door 210 so that the opening and closing door 210 is continuously maintained.

As described above, according to the automatic roll toilet paper discharge device according to the present invention, since the roll toilet paper is automatically folded in a well-aligned state by the number of turns desired by the operator, the use of toilet paper is more convenient, and especially for those who are uncomfortable with one hand or the elderly. It is a useful design that can provide convenience.
