Abstract

PURPOSE: To accurately cut a paper towel one by one along perforation from a partly cut-off part by providing a tensile force to the paper towel caused by the difference in rotational speeds by a partly cutting mechanism of perforation consisting of a pair of delivery rollers. CONSTITUTION: Two shafts 35 and 36 being a pair of left and right shafts are freely rotatably supported under parallel condition by bearing through bushes 34 and 34 near the top end parts of side plates 31 and 31. Rubber rollers 37 and 38 comprising a partly cutting-off mechanism of perforations are fixed at the central parts of the shafts 35 and 36. The delivery roller 37 and the drawing-and-delivery roller 38 are rotated at high and low speeds, respectively to deliver the apex of the paper towel. When the next perforation part passes through between the delivery roller 37 and the drawing-and-delivery roller 38, the central part in the longer direction of the perforation is torn over a specific length and is under an opened condition by the difference in rotational speeds of both rollers.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a paper towel dispensing machine, and more particularly to a paper towel dispensing machine equipped with a mechanism for partially separating perforations.

[Prior Art] A paper towel dispensing machine is known in which a band-shaped paper towel with perforations at predetermined intervals is wound into a roll, stored in a dispensing machine main body, and the paper towel is fed out in fixed length increments.

With this type of paper towel dispensing machine, the user must pinch the end of the dispensed paper towel with his or her fingertips,
By pulling strongly, the paper towel is cut from the perforations, and paper towels cut into predetermined lengths are used.

[Problems to be Solved by the Invention] However, it is rare for paper towel users to accurately grasp the bottom end of an unrolled paper towel with the fingertips of both hands and carefully pull it out. , often pulled with one hand or only at one corner.

In this case, the force is not concentrated at the perforation, and the towel is cut from other parts, making it inconvenient to use and causing problems such as the towel not being fed out accurately. there were.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a set of feeds that applies a tensile force to the paper towel and cuts the central part of the perforation over a predetermined length. A structure is adopted in which a part of the perforations made of rollers is separated.

[Function] The above-mentioned mechanism for separating part of the perforations, which is made up of a pair of feed rollers, applies a tensile force to the paper towel due to the difference in rotational speed or frictional force, so the sewing machine, which is the weakest part of the paper towel, Part of the eye can be removed. This part of the perforation is cut off before the paper towel is cut from the perforation, so when the bottom edge of the paper towel is pinched and pulled when cutting the vapor towel, the force is concentrated on the part that has been partially cut off. , since this force is distributed along the perforations, the paper towel can be cut precisely along the perforations.

Next, the method of use and operation of the paper towel dispensing machine constructed as described above will be explained with reference to the flowcharts shown in FIG. 9 and subsequent figures.

FIGS. 9 and 10 are flowcharts for explaining the operation. FIG. 9 shows the overall flow of the operation, and FIG. 10 shows the detailed operation of the main parts.

First, I will explain the overall flow.

In step S1 shown in FIG. 9, paper towels are set. At this time, the cover 3 must be opened and the middle frame 2 must be tilted toward the front. but,
In the initial state, the flat portion of the thin wall portion 12 of the shaft 11 located in the circular hole 33 on the back side of the notch 32 formed at the upper end of both side plates 31 and 31 of the middle frame 2 is on the entrance side of the notch 32. This state is perpendicular to the straight line extending from the direction toward the circular hole 33.

Therefore, the upper end of the middle frame 2 does not come off the shaft 11, and even if you try to open the cover 3 by pinching the lower end of the cover 3, the rear end of the upper end of the cover 3 and the upper ends of the left and right arms 51, 51 of the middle frame 2 The cover 3. I can't open it either. That is, both the cover 3 and the middle frame 2 are in a locked state.

If you want to open cover 3 and middle frame 2 from this state, use shaft 1.
1 is rotated so that the plane portion of the thin portion 12 is parallel to the axial direction of the notch portion 32.

The shaft 11 may be rotated by fingers or by fitting a screwdriver or other jig into grooves 14 formed at both ends of the shaft 11.

By making the flat surface of the thin portion 12 parallel to the axial direction of the notch 32, the shaft 11 can be easily pulled out from the notch 32. In this state, the battery 64 and the like are housed on the middle frame 2 side, and the weight is heavy, and the rear end of the lower part of the left and right side plates 31 and 31 is connected to the shaft 25 at the lower end of the base frame 1. Since the inner frame 2 is rotatably supported on the shaft 25, the inner frame 2
Since the entire body has a rotational moment that rotates toward you, if you pinch the bottom end of the cover 3 and push the cover 3 upward, the cover 3 will open centering on @11. Then, middle frame 2
is rotated toward this side by its own weight and pulls the upper rear ends of the side plates 73, 73 of the cover 3 downward via the left and right arms 51, 51, so that the opening movement of the cover 3 is further accelerated, and the cover 3 is opened. Opens almost automatically. This state is shown in FIG. 8, where the arc-shaped support frames 49, 49 are opened upward.

In this state, the cover 3 and the middle frame 2 maintain a balance,
Both remain open. Like this, cover 3 and middle frame 2
Place the rolled paper towel 4 on the left and right support frames 49.49 with the paper towels open, pull out the tip, and pass it over the top of the rubber rollers 37.38 to the front side of the front plate 30. Place it in the desired position and use a paper towel 4
Set. This is the stage of step S1 shown in FIG.

After setting the paper towel 4 in this way, the cover (front lid) 3 is closed in step S2. cover 3
When the cover 3 is closed, the cover 3 is rotated counterclockwise about the shaft 11 in FIG.
It is rotated clockwise in FIG. 8 about the center.

When the middle frame 2 is rotated in the clockwise direction in FIG. Ru. In this state, cover 3,
Although the middle frame 2 is now completely closed, it is not yet locked.

Therefore, when the shaft 11 is rotated 90 degrees clockwise or counterclockwise in FIG.
2, the middle frame 2 is locked, and the cover 3 is also locked.

By the way, when the cover 3 is closed, the tip of the detection piece 23 provided on the base frame 1 side touches the micro switch S on the inner frame 2 side.
1 and turns it ON (step 83). When the microswitch $1 is turned on, the power is turned on in step S4, and subsequently, in step S5, the control circuit configured on the printed circuit board PC is reset.

On the other hand, when the cover 3 and the middle frame 2 are closed, the roller 2
0 is pressed onto the feed roller 37 and the roller 28 is pressed onto the pull-out feed roller 38 via the drawn out paper towel. The pressing force is provided by springs 22 and 29.

The operation immediately after the circuit is reset, that is, the first operation after the paper towel is set, starts with the control in step S7 shown in FIG. 10, and when step 324 ends, the towel setting is completed. If so, the control in step S6 is repeated. Details of the control content in step S6 will be explained with reference to FIG. 10.

Also, the operation after setting the towel will be explained.

Normally, the tip of the set paper towel is placed between the feed roller 37 and the rotating frame 53, and
It is located outside of 0.

The rotating frame 53 is rotating clockwise in FIG. 1 due to its own weight, and since the magnet 58 is close to the reed switch 59a, the reed switch 59a is turned on.

In other words, there is no paper towel on the rotating frame 53 (SW2). After the circuit is reset in step S5, the rotation frame 53 (SW2
) Detects that there is no paper towel on top and steps 31
8, after waiting for a certain period of time (Bose), step 819
The motor 40 starts rotating at , and at the same time the preset ■
mode is set. The rotation of the motor 40 is transmitted to the shaft 35 via a worm gear 42 and a worm wheel 43, and a small diameter pulley P1 fixed to the thin end of the shaft 35.
The shaft 36 is rotated via the belt B1 and the large diameter pulley P2.

As a result, the feed roller 37 is rotated at high speed and the drawer feed roller 38 is rotated at low speed, and the leading end of the paper towel is fed out.

On the other hand, in the preset mode (2), the amount of paper feed after the reed switch 59a is turned on is set. This paper feed suspension is set in advance, and the set amount is detected by counting the number of teeth of the gear 44 by a sensor inside the frame 45.

At this time, the paper feed is carried out at the maximum, and approximately one sheet of paper towel is fed.

Eventually, the tip of the paper towel will move to the rotating frame 53 (SW2).
The reed switch 59a is turned OFF because the magnet 58 is separated from the reed switch 59a and the reed switch 59a is turned OFF. This is step 320
It is.

When the reed switch 59a is turned OFF, it means that the tip of the paper towel has been detected, so the preset (2) is reset in step S21, and the preset (2) is newly set in step 822. In this mode, the amount of paper feed after the reed switch 59a is turned off is set, and detection of this amount of paper feed is the same as the method of counting the number of teeth of the gear 44 described above.

Then, in step 323, when the preset paper feed amount (preset ■) is counted up, the motor 40 stops, and the tip of the paper towel 4 is moved to the rotating frame 53.
The paper towel is now exposed downward from the front surface of the switch plate 66 by a predetermined amount, for example, j2, and the setting of the paper towel is completed. This is step 324, which is the standby state of step S8 for using the towel. The state at this time is shown in FIG.

At this time, the next perforation has already been moved to the feed roller 3.
7 and the drawer feed roller 38,
Due to the difference in the rotational speeds of both rollers, the central portion in the longitudinal direction of the perforation is torn over a predetermined length, leaving it open. This opening is designated by 4a.

Further, if the tip of the set paper towel 4 is set not between the feed roller 31 and the rotating frame 53 but beyond the rotating frame 53, the towel is placed on the rotating frame 53 in step S7. In this case, the system enters a standby state in step S8.

Next, normal use after completing the towel set will be explained.

There are two ways to use it.The first method is that when the switch plate 66 is pressed in the standby state step S8 to step S9, the microswitch S is activated via the shaft 67.
2 is turned ON. Since the rotating frame 53 detects the presence of a paper towel in step S10, step 81
1, the motor 40 starts rotating. The connected feed roller 3713 and drawer feed roller 38 rotate to feed the paper towel.

At the same time, preset ■ is set. In this mode, the amount of paper feed after the switch plate 66 is pressed is set.

The paper feed amount is detected by the method of detecting the number of teeth of the gear 44, similar to the aforementioned preset (2) and preset (2). While the number of teeth is being counted, the presence of the paper towel is being detected by the rotating frame 53 (step 51).
2).

Then, in step 313, when the preset paper feed number is counted up, the motor 40 stops and the tip of the paper towel hangs down by an additional length of 1 to make it easy to tear (step 514).

In this state, even if the switch plate 66 is pressed again through a paper towel, the motor 40 will not operate (step 515).
Continuous use is prevented.

Next, in step 816, when the lower end of the paper towel 4 is pulled by hand, the force is concentrated on the opening 4a of the paper towel 4, so the paper towel 4 is reliably cut along the perforations and with a small force. .

When the paper towel is cut, the rotating frame 53 no longer contacts the paper towel 4 in step S17, and returns to its original state due to its own weight. After waiting for a certain period of time in step S18, in which it is detected that the paper towel has run out, in step S19. As soon as the motor 40 rotates and sends out the next paper towel, the preset mode (2) is set. Thereafter, the process proceeds to step 824 in the same manner as described above, and the process enters the standby state for the next use, step S8.

Another method of use is to pull and cut the lower end of the paper towel 4 hanging down from step S8 in the standby state to step 816. Even in this case, the paper towel 4 is cut reliably along the perforation in step 817.
The process proceeds from step 324 to step S8 in a standby state for the next use. For normal use, this step S6
is performed repeatedly.

The paper towel is used in this way, but if the leading edge of the paper does not appear forever in step 820 and the tooth number count value becomes equal to the setting value of preset ■, it is detected that there is no paper towel, and in step S25,
The value of preset (2) is counted up, the motor 40 is stopped, and the process moves to step 326 in FIG.

The paper feed amount by preset (2) is larger than the paper feed amount by preset (2), and the paper feed amount by preset (2) is larger than the value of preset (2).

In step 826, even if the switch plate 66 is pressed,
The motor 40 is not driven and paper is not fed.

Note that during the above-mentioned operation, for some reason, the cover 3
When the microswitch $1 is turned off in steps 828 and 829, the li source is turned off and paper feeding is not performed. If you close cover 3 again, step s
2, as described above.

If the paper towel in step 826 runs out, the cover 3 is opened in step 827, and the microswitch S1 is turned OFF in step 828.
At step 829, power is turned off. In this state, replace the vapor towel as described above in step 5.
30) Return to step S1 and repeat the operations described above.

[Second Embodiment] FIG. 11 explains a second embodiment of the present invention. In this embodiment, the length of the drawer feed roller 38 is made almost the same as the width of the paper towel, and the length of the feed roller 38 is approximately the same as the width of the paper towel. 37
The length of the paper towel is significantly narrower than the width of the paper towel, and other parts are the same as those of the first embodiment, so they are omitted.

Even if the above-described structure is adopted, the same effects as in the above-described embodiments can be obtained.

[Third Embodiment] FIG. 12 explains a fourth embodiment of the present invention. In this embodiment, the feed roller 31 has a large diameter, the pull-out feed roller 38 has a small diameter, and both are Rotating at the same rotation speed.

When such a structure is adopted, the circumferential speed of the feed roller 31 becomes faster than that of the pull-out feed roller 38, so a tensile force acts on the paper towel, making it possible to partially cut off the perforations, as described above. The same effects as in the embodiment described above can be obtained.

[Effect 1] As is clear from the above explanation, according to the present invention, since the present invention is equipped with a mechanism for partially cutting off the perforations consisting of a set of O-lers, when cutting the vapor towel, it is not possible to partially cut off the perforations. It is possible to accurately cut one sheet at a time along the perforations from the cut portion.
