Abstract

The extruder operating by a motor and reduction gears has a screwed shaft mounting a channel member and revolving in the regular or reverse direction to advance or retreat the channel member that squeezes a tooth paste tube placed over the shaft. The movement of the channel member is controlled stepwise under a program with non-contact or contact type sensors set on the predetermined positions. The travel of the member being controlled by the sensors extrudes only a certain amount of the paste at a time, while the squeezed and emptied portion of the tube is rolled up in the member to make easy replacement of the tube. After an extrusion of the paste, the tube mouth is capped with a cover after cutting the extruded paste to prevent foreign matters from collecting on the mouth. The extruder is handy and clean to be reliable.

8 is a flowchart for explaining the operation of the apparatus of the present invention as a program embedded in the above-described program memory of the microprocessor 100.

The operation relationship of the toothpaste automatic extrusion device of the present invention configured as described above will be described below with reference to the accompanying drawings.

That is, in the combined state as shown in FIGS. 2 and 4, the door 34 of the upper case 2 is frozen, and the rear end of the toothpaste tube 40 is interposed between the gaps of the pressure roller 6 of the channel 4. When fitted, the toothpaste tube 40 is held in a horizontal state by the conveying belt 9 folded downward while being supported by the pressure roller 6 of the channel 4.

In such a state, when the toothbrush 41 is to be buried in the toothpaste, the toothbrush 41 is pushed through the front shield 25 of the toothpaste housing 3 and the shield 25 is hinged by the pushing operation of the toothbrush 41. It touches the floor in the toothpaste storing part 3 at the point center.

If the toothbrush 41 is continuously pushed in the direction in which the shield 25 is opened, the toothbrush 41 is guided along the toothbrush guide piece 24 formed at the bottom of the toothbrush housing 3 to fix the rib in front of the main body 1. (28) is located in the front lower part of the toothpaste outlet (18). At this time, the toothbrush (41) inserted into the toothbrush housing (3) by the toothbrush sensor (S ₁ ) fixedly installed opposite to both inner walls of the toothbrush housing (3).

When the toothbrush detection signal detected from the toothbrush sensor S1 is input to the microprocessor 100 as shown in FIGS. 7 and 8, the microprocessor 100 outputs a solenoid driving signal through its output terminal to open and close the lid. Operate the solenoid drive unit 200 for.

Accordingly, the solenoid 20 fixed to the receiving groove 30 of the toothpaste discharging part 18 is driven and the cover 31 fixed to the operating rod 20 'thereof is the same as in the state of FIG. That is, the outlet 38 of the toothpaste discharge part 18 is opened in the state which closed.

At the same time, the microprocessor 100 also outputs the forward rotation driving signal of the motor 11 to the motor guide 150 connected to the output terminal thereof, and when the motor driving unit 150 rotates forward, the motor 11 rotates forward. Drive the reducer 12 while being driven.

The reducer 12 decelerates the rotational force of the motor 11 at a constant speed, and the deceleration power thereof is transmitted by the bevel gear 13 to the bevel gear 15 of the screw shaft 5 engaged with the deadlock. .

Accordingly, the bevel gear 15 of the screw shaft 5 rotates the channel 4 fixedly installed in the upper portion of the screw shaft 5 in the forward direction of the motor 11 in the forward direction, thereby interlocking with the screw shaft 5. By rotation, the channel 4 moves forward.

At this time, the channel 4 moving forward is guided to guide grooves 10a and 10b of guide supports 10 and 10 'formed on both inner walls of the body 1 by guide protrusions 8 protruding from both sides thereof. Is moved.

In addition, the toothpaste tube 40 taken between the pressurizing rollers 6 of the channel 4 during the forward movement of the channel 4 is transferred to the conveying belt 9 freely passing through the passage 21 of the toothpaste 18. It is pulled to the insertion hole 23 side of the toothpaste discharge part 18 by this.

In this way, the toothpaste tube 40 taken from the channel 4 is moved forward by the transfer belt 9, and when the optical sensor S ₂ for detecting the toothpaste proximity position is installed, the microprocessor of FIG. 100 decelerally controls the rotational speed of the motor 11 through the motor driving unit 150 to drive the state in which the rotational speed of the motor 11 is decelerated.

In accordance with the deceleration rotation of the motor 11, the reducer 12, the bevel gears 13, 15 and the screw shaft 5 correspondingly decelerate rotation, and toothpaste towed to the channel 4 and the transfer valve (9). The tip end of the tube 40 is gradually inserted into the insertion hole 23 of the toothpaste discharge portion 18.

At this time, when the tip of the toothpaste tube 40 is inserted into the insertion hole 23 to operate the contact of the limit switch LS protruding from the inclined surface 39 thereof, as shown in FIG. 8, the microprocessor 100 may include a motor driving part ( The controller 150 is turned off and the motor 11 of the forward rotation drive is stopped.

Advancing operation of the toothpaste tube 40 fixed to the channel 4 while the rotation of the reducer 12, the bevel gear 13, 15, and the screw shaft 5 also stops as the motor 11 is stopped. In this case, the front end portion of the toothpaste tube 40 is pressed against the inclined surface 39 while pressing the contact point of the limit switch LS protruding from the inclined surface 39 through the insertion hole 23. At this point, the pressing roller 6 of the channel 4 presses the rear end of the toothpaste tube 40 by a force that moves in the forward rotation direction of the screw shaft 5.

Accordingly, the toothpaste tube 40 is extruded through the outlet 38 of the toothpaste discharge portion 18 in a predetermined amount by the pressurizing action of the pressure roller 6 as shown in Figure 4a while the toothbrush housing ( 3) is attached to the toothed portion of the toothbrush 41 inserted in.

At this time, the toothpaste sample 42 to be deposited is moved by the motor 11 while being driven until the tip of the toothpaste tube 40 is in close contact with the inclined surface 39 of the toothpaste discharge portion 18 by pressing the pressure roller 6 The pressing force of) acts and extrudes, and in the state where the tip of the toothpaste tube 40 is completely in contact with the inclined surface 38, the limit switch LS enters the on-contact operation and the motor 11 is stopped. At this time, since the pressing force of the pressurized roller 6 is in a state of being released, the toothpaste sample 42 from the toothpaste tube 40 is no longer discharged.

As described above, in the state in which the toothpaste sample 42 is extinguished and stopped, the microprocessor 100 sets the time set by the up counter operation of the omitted timer built in the microprocessor 100 from the on-contact point of the limit switch LS. After the elapse of time, the solenoid 32 installed in the toothpaste discharging unit 18 is turned on / off by controlling the toothpaste cut solenoid driving unit 300 to be driven for a predetermined time and then off through its output stage. The actuating rod 32 'of the solenoid 32 also moves forward toward the outlet 38 side as shown in FIG. 5B, and is then restored by the rear layer spring 37' and coupled with the actuating rod 32 '. 33) is moved forward and backward so that the toothpaste sample 42, which has been extruded into the outlet 38, is cut off, and the cut toothpaste sample 42 is deposited while freely falling on the toothed part of the toothbrush 41.

In addition, when the motor 11 is driven in the forward rotation direction, the transfer belt 9, which is holding the toothpaste tube 40 while moving the channel 4 forward by the forward rotation of the screw shaft 5, also includes the toothpaste discharge section ( It is conveyed while being carried by the guide roller 19 through the passage opening 21 of 18) and is wound in the wound part 22 by the restoration action of the wound part 22 installed in the lower part of the toothpaste discharge part 18. .

On the other hand, after the toothpaste sample 42 cut into a predetermined amount is deposited on the toothed portion of the toothbrush 41, and withdraw the toothbrush 41 inserted into the toothbrush housing 3, the shield 25 is hinged at its lower end. By reducing the toothbrush storing section 3 to its original position, it blocks the inflow of air from the outside, thereby preventing infection by external air.

At the same time, while the toothbrush sensor S1 fixed to both inner walls of the toothed male part 3 is opened to each other, the receiving side transmits an on-signal (without toothbrush).

At the same time, the microprocessor 100 of FIG. 7 turns off the cover opening / closing solenoid driver 200 connected to the output end thereof in an on operation, and is fixed to the upper receiving groove 30 of the toothpaste part 18 by the same. (20) is also turned off while the operating rod 20 'is returned to its original position by the restoring force of the spring 37, and the cover 31 is returned to the outlet 38 side so that the outlet 38 is closed.

At the same time, a motor reverse rotation driving signal is also sent to the motor driving unit 150 to control the switching of the motor driving unit 150 to reverse rotation operation.

Accordingly, the motor 11 and the reducer 12 are started to rotate in reverse to rotate the bevel gears 13 and 15 and the screw shaft 5 in the reverse direction of the forward rotation direction. The channel 4 coupled with the screw according to the reverse rotation of the screw groove 5 is moved backward in the forward state while towing the toothpaste tube 40 fixed to the pressure roller 6 to the rear. In addition, the conveying belt 9 which is wound around the winding unit 22 by the backward movement of the channel 4 is also pulled in the channel moving direction, and thus, the toothpaste tube 40 is not moved.

As such, the toothpaste tube 40 is press-fixed and fixed as much as the toothpaste sample 42 is extruded by the pressure roller 6 of the channel 4 moving to the rear side. ) Is gradually exited from the insertion hole 30 of the toothpaste discharge portion 18.

At this time, when the rear part of the channel 4 to be moved backward reaches the position of the backward stop position detecting optical sensor S ₃ provided on both inner walls of the main body 1, the channel detection signal detected from the sensor S ₃ is micro. Transmitted to the processor 100.

At the same time, as shown in FIG. 8, the microprocessor 100 turns off the motor driving unit 150 of the reverse rotation driving, so that the motor 11 stops the reverse rotation driving.

Accordingly, while stopping with the power transmission unit (reduction gear, bevel gear and screw shaft) is stopped when moving the channel (4), the forward and reverse operation of this description is to place the toothbrush 41 in the toothbrush housing (3). When subtracted, the above operation is repeatedly performed.

On the other hand, whenever the toothpaste sample 42 of the toothpaste tube 40 is exhausted by repeating the above-described forward and backward operations, the rear end closed portion of the toothpaste tube 40 is pressurized roller 6 of the channel 4 as shown in FIG. As it is pushed backward through the), it is wound spirally by the waste tube storage port (7) can be easily processed during exchange. In addition, the device of the present invention may be used for various purposes by attaching a toothbrush holder or a toothbrush barrel 50 for storing the toothbrushes of the user on the outer wall of the main body 1.

As described above, the apparatus of the present invention is configured to forward and backward the channel for fixedly compressing the toothpaste tube by pressing and rotating the screw shaft forward and backward on the screw shaft by the decelerating movement means of motor power transmission. The position detection at the time of movement is detected by a plurality of non-contact and contact sensors installed at each setting position, and detected by a plurality of non-contact and contact sensors installed at each setting position, and by a plurality of non-contact and contact sensors installed at each setting position. By detecting and prosramically controlling the toothpaste, the toothpaste extruder can be miniaturized and the manufacturing cost of miniaturized toothpaste can be reduced. At the same time, to close the toothpaste outlet after the toothpaste withdrawal. It is possible to maximize the hygiene efficiency by completely blocking foreign matters from the outside by means of the means. Also, each time the toothbrush is inserted and removed, the detection means of the position sensors can move the inside and back of the toothpaste tube as a single stroke. Toothpaste is extruded by a proper amount, so you can always use the fresh toothpaste sample, and furthermore, by installing the electrical components to be sealed off from the outside of the toothpaste discharged to protect the device to prevent electric shock and short-circuit early due to use Of course, there is a feature that can provide safety and reliability by not hitting the user at all.
