Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The industrial field of application of the present invention is the field of a towel dispensing machine configured to be able to wind and feed towels with great precision. .

[Prior Art] Various types of towel dispensing machines are known that store a rolled towel, pull out the towel to a position where it can be used by a user, and automatically wind up the used towel.

In conventional towel dispensing machines of this type, the towels hang down in a loop below the dispenser, but if the loop is always formed, it looks unsightly. Otherwise, dirt etc. will stick to the towel and it will be extremely unsightly.
I am a student.

Therefore, a towel dispensing machine has been proposed that automatically winds up the loop portion of the towel after use.

[Problems to be Solved by the Invention] Conventional towel dispensing machines of this type are equipped with rollers corresponding to the taxi rollers of the present invention for storing and dispensing used towels. ing. Towels were suspended from these rollers, and used towels were taken in and out as the rollers moved up and down.

However, in the past, this roller was simply rotatably mounted in the form of a free roller (because it was rotated by the frictional force of the towel at 'J', the towel could not be wound up smoothly).

In other words, the space in which the rollers move up and down is extremely narrow, and the towels suspended reciprocatingly by the rollers come into contact with the back plate of the dispensing machine, and even when the rollers descend, the friction between the towel and the back plate prevents the towels from being lifted. There were cases where the towel remained in the gap and the towel was not fed out even when the roller reached the lowest end. In order to solve this weakness, this gap must be widened, and as a result, the feeding machine itself becomes larger, resulting in missing fish.

Means for Solving Problem 1 In the present invention, in order to solve the above-mentioned problem, a pressing force is applied to J: which is constantly in contact with the taxi roller along the path of the taxi roller that moves up and down. We adopted a towel forced entry/exit mechanism with a given friction member.

[Function] By adopting this J: Una structure, the taxi roller is forcibly rotated when it goes up and down, so the towel wrapped around it will not move in the winding direction or the feeding direction. The towels are forcibly moved, allowing smooth storage and delivery of the towels.

In addition, even if the back plate of the device is near the towel suspended by the taxi roller, that is, even if the towel moves up and down within an extremely narrow gap, the taxi roller will reliably rotate in the forward and reverse directions. The rotating friction force forces the towel to be stored and fed out, and the towel does not move forward from the taxi rollers and remain in the gap due to the friction force with the back plate. As a result, the gap can be narrowed and the towel arrangement "rV3" can be made smaller.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

According to the present invention, the A-ru arrangement plate 1 includes a device main body 2, a towel tray 3 rotatably installed at the lower front side of the device main body 2, and a towel tray 3 that can be freely opened and closed at the upper end of the device main body 2. It consists of a cover 4 that can cover the front surface of the dispenser, and a mounting plate 5 for attaching the main body of the dispensing machine to a wall surface or the like.

The details of each part will be explained below.

The main body 2 has left and right side plates 6, 6, and a back plate 7, and a frame body 8 with an open front side and a 7-shaped cross section. A rotating frame 9.10 is arranged at a closer position.

Each rotating frame9. It is formed as a vertically longer frame than the IOG. The upper end of one rotating frame 9 is wide and has a cross section of
” 7-shaped bent portion 11 is formed outward.

Further, a bent portion 9a is formed outwardly over almost the entire length of the front side edge of the rotating frame 9.

A "1-" shaped bent part 9b is formed outward at the lower end of the rotating frame 9, and one end of the frame 12 is arranged along the outer edge of this bent part 9b. .

This frame body 12 is formed by bending a band-shaped metal plate with a 90-degree stepped bend part in the middle. A shaft 13 is horizontally suspended between them. The outer end of this shaft 13 is movably fitted into a long hole 13a formed along the axial direction in a part of the rear end of the sea urchin frame 12, as shown in FIG.

On this i11+13, a Jens block 1-14 is rotatably supported between the frame body 12 and the wide portion at the lower end of the rotating frame 9.

Further, one end of a shaft 15 is fixed to a bent portion 12a in the middle of the frame 12, and the other end of this shaft 15 is fixed to a bent portion 12a in the middle of the frame 12. IJ frame 9
It protrudes toward the bent portion 9b at the lower end.

A spring 1G is wound around this shaft \15, and this spring 16 is in a state of being elastically loaded between the bent portions 9b and 12. Therefore, a force is applied to the bending portions 12a and 9b in the direction of separating them from each other.

In addition, a long hole 12 is provided in the front end of the frame 12 in the axial direction.
b is formed.

Further, a long hole 17 is formed at the lower end of the side plate 6 in correspondence with the long hole 121), and a shaft 18 is fitted into the long holes 1211 and 17 so as to be movable from the outside of the frame 12. and is fixed to the side plate of the towel tray 3, which will be described later.

Two upper and lower sliding plates 19, 19 are slidably provided perpendicular to the axial direction of the rotating frame 9, penetrating the base of the bent portion 9a formed on the side edge of the rotating frame 9. ing.

A pin 20 serving as a stopper is provided protruding from the front end of the sliding plate 190 on the outside of the bent piece 9.

In the middle of each sliding plate 19, a cross section cut and raised from the rotating frame 9 extends through the base of a folded piece 21 shaped like an 11-1 in a freely openable manner, and a position beyond the folded piece 21 extends. Rotating frame 9
The support frame 22 is fixed to a bent portion of an elongated support frame 22 whose cross section is parallel to the letter "J". A friction member 23 made of rubber or the like is fitted and fixed within the support frame 22 over its entire length.

This friction member 23 projects toward the rear of the device.

Note that the length of this friction member 23 is shorter than the length of the rotating frame 9.10.

Roughly speaking, a spring 24 is stretched between the bending piece 21 and the sliding plate 19, and provides a force to move the friction member 23 rearward. 71 No. 25 indicates spring 2
The other end of the spring 24 is fixed to a protruding piece 21a cut and raised from the bent piece 21 with a screw that fixes the spring 4 to the threatening plate 19 side.

The above-mentioned structure shows a mechanism for attaching the friction sensing member 23 to the rotating frame 9.10, and provides forced rotation due to friction with a taxi roller, which will be described later. However, the structure for forcing the taxi roller to rotate is not limited to this mechanism;
The rear edge itself or a rubber-like member provided on the rear edge serves as the friction member 23, which is formed widely on the rear side up to the position where it contacts the roller, and when the taxi roller moves up and down. A mechanism for forcibly rolling the taxi roller past In1 using the contact friction force can also be used.

In addition, the upper end of the rotating frame 9 has an r L J-shaped bent portion 11.
The base of the pin 26 protrudes from the outer surface of the upper end of the side plate 6.
It is rotatably supported on a shaft.

The position of the pin 26, which serves as the pivot of the rotating frames 9 and 10, is horizontally toward the front side of the taxi roller 38, which will be described later, provided on the rotating frames 9 and 10. Due to this eccentricity, when the taxi roller 38 is pushed downward by the tension of the towel wrapped around the taxi roller 38, the rotating frames 9 and 10 use the pin 26 as a fulcrum. It rotates so that its lower end swings toward the front. This rotation turns on a switch S5, which will be described later, and stops the motor drive. In addition, in conjunction with the rotation of this rotation frame, a rotation plate (described later) rotates, and an adjustment roller connected to this rotation plate moves rearward, and this movement causes the rotation frame 9 to rotate. ,1
The above 1m switch of 0 is performed by iVI to ensure the ON operation of the switch S5.

The other rotating frame 10 is also formed almost similarly to the rotating frame 9, but is slightly different.

That is, a U-shaped support frame 27 that is open toward the outside is integrally formed at the upper end of the rotation frame 10, and a support frame 27 that is open toward the outside is formed on the front side edge of the rotation frame 10. Facing the bending part 10a
is formed, and a bent portion 10b is formed on the front side of the lower end portion.

-〇- Also, along the outer edge of this bent portion 10b, the frame 12
A frame 12 having the same 18 structures is placed in a symmetrical state, and a shaft 13 is horizontally suspended between the rear end of this frame 12 and the lower end of the rotating frame 10. The outer end is slidably fitted into a long hole 13a formed at the rear end of the frame 12.

A chain sprocket 14 is also rotatably supported on this shaft 13.

Also, one end of the shaft 15 is similarly fixed to the bent part 12a in the middle of the frame 12, and the other end of the shaft 111115 extends in the direction of the bent part 10b. A spring 16 is wound around this shaft 15, and a force is applied to both the bent portions 12a and 10b in the direction of moving away from each other.

A support frame 22 to which a friction member 23 is fixed is also attached to the rotating frame 10 side. Since its structure and shape are exactly the same as those on the rotating frame 9 side, the same or corresponding parts are given the same reference numerals to avoid duplication of explanation, and the explanation thereof will be omitted.

By the way, an elongated hole 121) is formed along the axial direction at the front end of the frame 120 on the rotating frame 10 side, and an elongated hole 17 is formed at the lower end of the side plate 6 opposite to this. has been done. The long holes 12b and 17 are inserted into the shaft 1 from the outside of the frame 12.
8 is fitted and fixed to the side plate of the towel holder 3, which will be described later.

Note that a limit switch S is installed inside the rear half of the frame 12 near the bent portion 12a of the frame 12 on the rotating frame 10 side.
5 is installed. This limit switch S5 is a switch that detects the rotational state of the rotation frame 10, as described in 112.

Furthermore, a printed circuit board P on which an electronic circuit for controlling the entire operation is mounted is fixed to the outer surface of the side plate 6 on the rotating frame 10 side.

A motor M2 is fixed to the upper end of the rotating frame 10 with its rotating shaft parallel to the axial direction of the rotating frame 10.

1-mgya 28 fixed to the output shaft of this motor M2
protrudes into the U-shaped support frame 27, and the support frame 2
Worm wheel 2 rotatably supported on the vertical wall of 7
8a (see Figure 9).

The two gears integral with the A-mov wheel 28a are meshed with a gear 31 fixed to one end of a shaft 30, which is provided on the vertical wall of the support frame 21 with resin.

Chain sprockets 1 to 32 integrated with this gear 31 and Chain sprocket 1 installed at the lower end of the rotating frame 10 4-1.
-14, an endless ladder engine 33 is strung between the two.

The other end of +kb30 extends through the upper end of the rotation frame 9, and a chain sprocket 34 is fixed on the outside of the rotation frame 9.

This chain sprocket 34 is installed at the lower end of the rotating frame 9 (
) A ladder chain 33 is stretched between the chain sprocket 14 and the chain sprocket 14 .

Therefore, when the motor M2 is rotated, the A-mgya 28,
shaft 3 through the A-me wheel 28a1 gear 29.31
0 is rotated, chain blocks 1 to 32 and 34 are rotated, and the ladder chain 33 is run.

However, the rotation frames 9 and 10 are connected to the pin 2 as described later.
6, but at this time each rotation frame 9.1
11III30, which is integral with 0, is also rotated.

Therefore, in order to prevent rotation of the shaft 30 from being obstructed, an opening 61 is formed on the back side of the upper end of the side plates 6, 6.

The upper end of a support plate 35 is fixed to the lower surface of the rear end of the support frame 27 at the upper end of the rotation frame 10, and the lower end of the support plate 35 has a limit switch S3-. 84 is fixed.

Further, the bent portion 11 and the support frame 27 at the upper end of each rotating frame 9, 10 are made to face upward by a predetermined distance beyond the upper end of the side plates 6, 6, and a top plate 36 is provided on the upper surface of the bent portion 11.27. is fixed.

The top plate 36 covers the rear of the upper end of the frame 8, and bent portions 36a formed at both left and right ends thereof are located outside the bent portions 11 of the rotation frames 9 and 10 and the support frame 27. .

By the way, both ends of a rough sea roller (storage roller) 38 are fixed to the rear end sides of the side plates 6, 6 of the left and right ladder chains 33, 33 through fixing members 37.

The circumferential surface of the taxi roller 38 is covered with a friction member such as rubber, and is fitted into a notch 6C formed in the rear edge of the side plates 6, 6 along the vertical direction.

The lower end of the notch 6C is continuous with the notch 6d facing the front side of each side plate 6.6.

Further, when the taxi roller 38 moves in the vertical direction, it comes into contact with the friction member 23 mounted on each rotating frame 9, 10, and is rotated by the frictional force.

As is clear from FIG. 8, both left and right end portions 38a, 38a of the taxi roller 38 are formed to have a smaller cross-sectional diameter than the central portion 38b. Small diameter left and right ends 38a, 38
a comes into contact with the friction part (No. 23.23, so the end 38a
The circumferential speed of the center portion 38b is higher than the circumferential speed of the center portion 38b, and as will be described later, the towel wound around the center portion 381) is wound up as quickly as possible and an unwinding operation is performed.

The friction member 23 is always pushed in the direction of contacting the taxi roller 38 by the tension of the spring 24. However, the spring 24 is provided to ensure contact, and if the dimensions of the members are properly set, the spring 24 is unnecessary.

Previous) When the rear end edges of the rotating frames 9 and 1o are used as the friction member 23 as in this book, the rear end edges bring the both ends 38a and 38a of the taxi roller 38 into frictional contact and force rotation. The center portion 38b is rotated at high speed in the same manner as above.

Incidentally, a substantially triangular rotating plate 39 is rotatably mounted inside each of the side plates 6, 6 and is rotatably supported midway through a support shaft 39b.

The support shaft 39b of the rotating plate 39 also serves as a support shaft for the take-up roller 41. An arcuate guide plate 41a is provided behind the take-up roller 41 along its periphery.

A long hole 39a is formed vertically at the upper end of each rotating plate 39, and a long hole 40 is formed horizontally in the side plates 6, 6, overlapping the upper end of this long hole 39a. There is.

A pin 9 protrudes from the inner surface of each rotating frame 9, 10.
d and 10d are slidably fitted into these long holes 39a and 40.

In addition, there is an adjustment [1-ra 42] between the lower ends of the rotating plates 39 and 39.
is suspended horizontally.

On the other hand, on the outside of one of the side plates 6, a motor M3 is arranged with its axial direction perpendicular, and the motor M3 fixed to its output shaft is connected to the shaft 39b of the winding roller 41. It meshes with an A-me wheel 44 fixed to the outer end of the.

Therefore, when motor M3 rotates, t-mgya 43, tA
The take-up roller 41 is rotated via the roll wheel 44, and a roll-shaped towel can be wound up as will be described later.

By the way, in the side plates 6, 6, a long hole 4G into which the used towel take-up shaft 45 is fitted is formed diagonally from above the front side of the side plates 6 toward the center of the take-up roller 41. There is.

The circumference of the elongated hole 46 except for the upper end is within = 16
- a bent edge 47 which is inclined and extruded towards the side;

This J: By forming the bent edge 47, the long hole 46
is located inside the inner surface of the side plate 6, and the upper end of the elongated hole 46 is open. The winding shaft 45 can be easily inserted into the long hole 46 from the upper end of the long hole 46 at the inside of the winding shaft 45. Components, etc. can be effectively arranged in the structure, and the device can be downsized due to the fact that the shaft does not protrude.Furthermore, the bent edges serve as ribs on the side plates, and the mechanical strength of the side plates can be improved.

In addition, since this bent edge only contacts the end surface of the used towel roll wound on the take-up shaft, the frictional force is significantly reduced compared to the conventional case where the entire side plate is in contact. This makes winding easier. Furthermore, this folded edge comes into contact with the end surface of the rolled towel, thereby preventing the so-called bamboo-shaped winding and making it possible to flatten one end surface 17 and realize beautiful winding.

On the other hand, the towel tray 3 is not shown in FIG. 5 and is constructed as shown in FIG.

That is, the towel tray 3 has left and right side plates 48, 48, and between them a support frame 49 having an arcuate cross section is connected to the take-up roller 41.
It is suspended horizontally with its opening facing the direction.

Further, a supply roller 50 is rotatably supported between the upper ends of the side plates 48, 48 on the near side.

Bushes 52 are fitted and fixed to both ends of the supply roller 50, and are rotatably fitted onto a support shaft 51 inserted through the supply roller 50.

A plurality of small holes 52a are formed on the outer surface of the bushing 52 at equiangular intervals on the same circumference, and a clutch plate 53 is fixed to the support shaft 51 on the outside of the bushing 52.

This clutch plate 53 is formed by punching a leaf spring, and has a plurality of arms 53a, and a protrusion 53b that fits into the small hole 52a is protruded from the tip of each of the eight arms 53a.
When the support Rib 51 in the figure is rotated counterclockwise, the protrusion 53b is fitted into the small hole 52a. The bushing 52 rotates together with the supply roller 50 in the towel feeding direction, but if only the supply roller 50 is rotated in the opposite direction or in the counterclockwise direction in FIG. 5 with the support shaft 51 fixed, the clutch plate 53 is configured to slip.

Further, a support plate 55 is fixed to the inner side of a bent portion 48a protruding outward from the front side edge of one side plate 48 by screws 54.

A motor M1 is fixed to the outer surface of the side plate 48 inside the support plate 55.

Worm gear 56 fixed to the output shaft of this motor M1
is engaged with a worm wheel 57 that is rotatably supported between the support plate 55 and the side plate 48, and this worm wheel 57 is connected to the gear 5 fixed to the outer end of the support shaft 51.
It meshes with 8.

Therefore, when the motor M1 is rotated in the towel supply direction, the supply roller 5 is rotated through these gears 5B, 57, and 513.
0 is rotated.

Note that an arcuate notch (cam) 52h (71) is formed in the center of the outer surface of the bushing 52, and the actuator 59 of the limit switch S1 is inserted into this notch 52b.
The free ends of the towels are fitted to form a structure that allows detection of the towel supply status.

In addition, what is indicated by n960 in Fig. 5 is LL support 111.
This is a bearing member that supports the other end of 151, and is fixed to the outside of side plate 48 with screws 61.

On the other hand, an opening 62 is formed at the corner of the lower end of the bent portions 48a, 48a formed on the front side edges of the left and right side plates 48.4B of the towel tray () 3, and the space between them is Part 62
Bent portions 64 provided at both left and right ends of the switch plate 63 are inserted therein. The width of the bent portion 64 is smaller than the width and height of the opening 62, and the bending portion 64 can rotate within the opening 64.

In addition, elongated holes 65 are formed in the horizontal direction (91) below the front sides of the side plates 4B and 48, and protrusions 66a at both ends of the frame plate 66 are fitted into these elongated holes 6511, and are bent and fixed. be done.

The Ic bent portion 66 is formed on the front side edge of this frame plate 66.
h serves as a stopper that limits the rotation limit of the switch plate 63.

Further, a spring 67 is stretched between the bent portions 64 at both ends of the switch plate 63 and the lower part of the side plate 48, giving the switch plate 63 the ability to rotate clockwise in FIG.

Further, above one of the bent portions 64, a limit switch 82 for detecting suppression of the switch plate 63 is provided on the outer surface of the side plate 48.

Further, a limit switch S6 for detecting opening/closing of the cover 4 is provided at the upper end of the side plate 6.

As described above, the towel receiving number 3 having such a structure is arranged inside the side plate 6.6 of the frame 8 of the main body 2, and is inserted through the long hole 12b1 of the frame 12 and the long hole 17 of the side plate 6. 111118 is the screw hole 4 at the bottom of the front side of the side plate 48.
It is attached by being screwed onto 8b.

In addition, a cover 38 is installed on the upper side of the towel tray 3 so that it can be closed freely, and a new towel or a rolled up used towel can be placed at a distance of 11 m to prevent the two from coming into contact with each other. Care has been taken to prevent dirt from used towels from falling and adhering to them.

On the other hand, a long hole 68 is formed below the side plates 6,6.

The rear half of this elongated hole 68 is a horizontal straight part 68a, and the front half is an arcuate part 681 that becomes higher toward the front side.

The length between ib is approximately equal to the length of a frame 73 protruding from the back surface of the upper end of the frame 8 of the apparatus main body.

This frame body 73 includes an elongated plate-shaped frame plate 73a that surrounds the lower side of the shaft 30, as shown by the chain line in FIG. A space is defined below the shaft 30 to prevent this from happening.

Further, a bent portion 71d is formed at the outer edge of the second flat portion 71c at a right angle toward the device main body 2 side.

The distance between the bent portions 71d and 716 is 4-
The distance between the left and right frames 12.12 is approximately equal to the distance between the outer sides of the J rail.

On the other hand, the upper horizontal frame 72 is suspended horizontally on the upper ends of the first flat parts 71a, 71a of the left and right vertical frames 71, and
It is fixed by welding or the like, and the fixed position is a predetermined distance downward from the upper end of the first flat portions 71a, 71a.

At one end of the upper horizontal frame 72, a folded part 72 is formed at the lower edge of the upper horizontal frame 72 on the apparatus main body 2 side.

The lower horizontal frame 72 is fixed to the lowermost ends of the first flat parts 71a, 71a of the left and right vertical frames 71.71 by welding or the like with the spora 1 so that its lower edges are flush with each other.

Folded portions 72b are formed on the upper and lower side edges of the lower horizontal frame 72, respectively.

Next, the operation of this embodiment configured as above will be explained.

FIG. 12 is a flowchart 1 to 1 to explain the control operation of the towel dispensing machine, and FIG. 13 and the following are explanatory diagrams showing the operating state.
In the following explanation, the dynamicity will be explained based on the flowchart 1 diagram in FIG. 12 and with reference to FIG. 13 and subsequent figures.

First, the operation during normal use will be explained. Before the start of use, the towel 70 and each member are shown in FIG. 13(A).
, '(B) and are arranged as shown in FIG.

That is, the towel tray 3 is housed within the frame 8,
One end of the rolled towel 70 accommodated in the support frame 49 of the towel tray 1/3 passes above the supply roller 50 and is led out along the outside of the towel tray 1/3, and is guided to the switch plate 63.
, passes under the frame plate 66 in contact with the surface of the support frame 49 , passes through the outside of the adjustment roller 42 , and goes from the outside to the inside of the taxi roller (storage roller) 38 located at the upper limit of the rise. The towel is rolled up, passes through the inside of the towel that is in contact with the adjustment row 542, and is guided to the bottom point of the elongated hole 46 in contact with the guide 41a located on the back side of the take-up roller 41. It is wound (t tJ) on the winding shaft 45.

At this time, the take-up shaft 45 wraps the towel at least once (t
k: In contact with the take-up roller 41 in a rolled state.

In addition, in this state, the rotating plate 39 is pushed by the tension of the towel 70 and maintains a nearly vertical state, and the pin 9d
, 10d are located at the upper end of the elongated hole 39a and at the rear end of the elongated hole 40.

In this state, all drive sources are turned off.

In the set state described above, when the switch plate 63 is pressed from above the towel 70 in step n1 of FIG. 12, the limit switch S2 is turned on (step n2).
).

Then, in step n3, motors M1 and M2 start rotating.

As a result, in step n4, as a result of the rotation of the motor M1, the supply roller 50 is rotated counterclockwise in FIGS. 13 and 18, and the ladder chain 33 is run clockwise in FIG. 13 due to the rotation of the motor M2. Then, the taxi rollers 38 descend.

As a result, a new towel is fed out in step n5, but the used towel is not taken out.

At this time, the length of a new towel to be fed out is determined to be, for example, 20 cm, and the amount to be fed out is determined and detected by a limit switch S1 such as a notch (cam) 52b accompanying the rotation of the supply roller 50.

Then, in step n6, limit switch S1 is turned on, limit switch S3 is turned on, and step n
1, the motor M1. M2 stops.

This state is shown in gM14 diagrams <A), (B) and FIG. 19.

In this state, the towels are looped below the device, with new towels at the front and used towels at the back.

Then, in step n8, the limit switch Sl,
When it is confirmed that 83 is on, a timer (not shown) is activated in step n9, and in step n10, the timer 1 to up is started up to the value set by the timer.

Note that the timer is provided on the printed circuit board P side, and can set a set time within a predetermined range, that is, the time to finish wiping the hands.

After the predetermined period of time has passed and the user has finished wiping his or her hands, the motor M2 begins to reverse in step n11, and the ladder chain 33 moves counterclockwise in FIG. 20 n12. n13)
Mo → Be 1 When the taxi row 538 reaches the upper end, step n
13. At n14, limit switch S4 is turned on and motor M2 is stopped.

If there is still a towel in this state, that is, in the intermediate stage of using the unused towel 70, the process advances to step n15, where the limit switch S4 is turned on, the motor M3 rotates, and the winding roller 41 is moved in the towel winding direction. rotated to
The winding shaft 45 in contact with this is rotated together with the towel,
The used towel is rolled up (step n 16. n
17).

When the used towel is collected, the loop of the towel is released and the towel is stretched tightly with a predetermined tension, so that the taxi roller 38 is at the upper end position of the rotating frame 9.10. However, a downward force is applied to it by the rotating towel, and this acting force is applied to the rotating frame 9,
The lower end of the rotating frame is moved toward the front side around pin 26, which is the center of rotation of No. 10, and when this movement occurs, limit switch S5 is turned on and motor M3 is stopped.
18. n19), returns to step n1 and enters a standby state for next use. In order to further ensure this final operation, a shaft (not shown) is installed horizontally at the lower end of the rotating frames 9 and 10, and the towel is rotated from the bottom of the water body of the device to the outside of this shaft and moved upward. Since the amount of J and urchin circulating around the taxi roller is distributed, the shaft of the J lever moves toward the front side due to the towel tension, promoting the above-mentioned movement of the rotating frames 9 and 10, and turning on the limit switch S5. To take this shaft and pull it, install it between the Jens blockets 1 to 14.14 at the lower end of the rotating frame 9.10.

On the other hand, in step n14, if there is no towel after the motor M2 stops, that is, in the final stage of the unused towel 70, the process proceeds to step n20, and the limit switch S
4 is on, the motor M3 rotates, but in this case, when there is a towel, the J: sea urchin limit switch S5
is not turned on, so motor M3 continues to rotate.

However, in this case, the motor safety device is set so that each motor rotates in the forward and reverse directions for a certain period of time, for example 20 seconds, so the towel rotates for a certain period of time and the entire towel is wound up to the end. In this state, motor M3 stops (step n2
1. n22).

On the other hand, in the case of continuous use, in other words, immediately after the previous towel has finished wiping its hands, and the winding of the used towel has not started or finished, the next use will press the switch plate again. occurs.

In this state, as shown in FIG. 12, the device does not react at all even if the switch plate 63 is pressed until the state of step n11, and continuous use is not possible.

However, when the switch plate 63 is pressed in step T1 after the timer is activated, the motors M1 and M3 start rotating simultaneously in step 2. Then, in step T3, the supply roller 50 and take-up roller 41 start rotating. , feeding out a new towel in step T4,
The used towel is wound up at equal distances, and the control routine proceeds to step n9 and subsequent steps.

Continuous use is not possible after proceeding to the routine of step n9.

On the other hand, when the lid (cover) 4 is heard, the following J: eel control is performed.

When listening to cover 4, there are two cases: changing the towel and simply opening the cover.

In any case, it is not shown in Figure 12.
It becomes l operation.

That is, when the cover 4 is opened in step U1, the limit switch S6 is turned off in step U2, and all operations are reset in step U3.

Subsequently, in step U4, motor M2 starts rotating,
The taxi roller 38 begins to descend in step U5.

When the taxi roller 38 descends, the limit switch $3 is turned on in step U6, and the rotation of the motor M2 is stopped in step U7.

In this state, in step U8, decide which towel should be replaced with a new one or check the inside, and then proceed to step U8.
When the cover 4 is disturbed in step 9, the limit switch S6 is turned on in step U10.

In this state, all functions are restored and the process moves to step 01 and subsequent steps.

On the other hand, if the used towel is pulled at the point when it starts to be stored in the taxi roller 38 or the take-up roller 41, a large tensile force is applied to the towel, so the taxi roller 38 will first move downward. J: is about to be pushed down by the tensile force on the rotating frame 9, 1.
0, its lower end moves toward the front with the pin 2G as the center of rotation.

To move the rotation frames 9, 10 forward, pins 9d,
Rotating plates 39 and 39 in an interlocking relationship via 10d move so as to move the adjusting roller 42 backward with the take-up roller 41 as the center of rotation. This retreat of the adjustment roller 42
The forward movement of the rotating frames 9 and 10 is encouraged, and due to the synergistic action of the adjustment roller 42 and the rotating frames 9 and 10, the rotating frames 9 and 10 are reliably advanced toward this side as a result. As a result, the limit switch S5 is turned on, the rotation of the motors M2 and M3 is stopped, and the towel winding is stopped.

This operation is the operation of the safety mechanism shown in FIG. 12, which functions only when a towel is present.

By the way, when replacing the towel 70, use the towel tray C.
You have to pull out pool 3.

At this point, as described above, the cover 4 is opened to stop all control operations, but the operation of the towel tray 3 itself is as follows.

That is, Fig. 15 (A), (B) and Fig. 16 (A>, (
As shown in B), first pull the towel holder (ji 3) towards you.

At this time, the pin 69 is connected to the elongated hole 6 formed in the side plates 6, 6.
8, the shaft 18 is inserted into the elongated hole 1 of the frame 12.
2b and the long holes 17 in the side plates 6, 6.

With the towel tray 3 pulled out to the front as much as possible in this manner, the entire towel tray 3 is rotated counterclockwise in the drawings around the shaft 18, as shown in FIGS. 16(A) and 16(B). When the pin 69 is moved, the pin 69 moves in the arcuate portion 68b of the elongated hole 68, and the towel tray 3 is rotated toward the front side and opened.

With the rotation of the towel holder C 3, the frame 12 is pulled toward the front via the shaft 18, and the lower ends of the rotating frames 9 and 10 are also pulled toward the front. As a result, the pins 9d and 10d also move toward the front, so that the rotating plate 39, which is interlocked with the pins 9d and 10d through the elongated hole 39a, is shown in FIG. 15(A).

It is rotated counterclockwise as shown in FIGS. 16(B), 16(A), and 16(B).

As a result, the adjustment roller 42 moves to the rear of the frame 8.

As a result of this rearward movement of the adjustment roller 42, the space within the frame 8 is increased, and when replacing a new towel,
The operation of attaching the towel to the winding shaft 45 and the operation of wrapping it around the taxi roller 38 are extremely easy.

After replacing the towel in this way, return the towel tray 3 to its original state and close the cover 4, the device will immediately return to the state in which it can perform star 1~, and the control operation as shown in Fig. 12 will be performed. is possible.

By the way, during the vertical movement of the taxi roller 38, the taxi roller 3B moves in contact with the friction member 23, so the taxi roller 38 is forcibly rotated at the same time. There is little friction and towels can be stored smoothly. Also, the left and right end portions 38a of the small diameter portion
, 38a come into contact with the friction member 23, the circumferential speed of the central portion 38b, which is the large diameter portion, becomes extremely high, and the central portion 38b
Towels wrapped in towels can be taken out and put in forcibly and at high speed. Therefore, even if the gap between the taxi roller 38 and the back plate (not shown) of this dispensing machine is small, a towel inserted through the gap may be folded into the gap due to the contact resistance of the back plate, causing problems such as getting caught. The towels can be put in and taken out smoothly without any problems.

In other words, when the taxi roller 38 descends,
The taxi roller 38 rotates at high speed in a direction that feeds out the towel downwards, and due to this rotational tension, the towel between the adjustment roller and the taxi mouth is in a state of tension, and the towel
The towel comes into close contact with the circumferential surface of the roller 38, increasing the frictional force for feeding out the towel, thereby ensuring that the towel is fed downward. Therefore, the phenomenon of towel sagging inside does not occur. In addition, when the taxi ○-538 ascends, the towel is sent out from the taxi row 538 to the adjustment roller at high speed, reducing the tension of the towel traveling to the take-up roller.
By reducing the winding torque of the winding roller, winding can be performed reliably with low load.

[Effect] As is clear from the above description, according to the present invention, in a towel dispensing machine that stores and feeds out used towels using a taxi roller that moves up and down, friction is generated along the up and down path of the taxi roller. By arranging the friction member and pressing it in the direction in which it is constantly in contact with the taxi roller, the taxi roller can be forcibly rotated when the taxi roller goes up and down, and this rotational friction The force allows towels to be stored and delivered efficiently. Therefore, there is an advantage that the gap between the elevator spaces of the taxi rollers can be narrowed, and the towel dispensing machine can be made smaller.
