Note that a warning lamp 1 consisting of a light emitting diode or the like fixed to the support plate 13 is installed in the through hole 32b formed in the cover 32 disposed on the outside of the side plates 6, 6 of the frame 7 on the main body side.
One end of 02 is facing up, and as will be described later, when the remaining amount of unused towels is low, the light is turned on to prompt the user to replace the towels.

Next, the operation of the towel dispensing machine configured as above will be explained.

At the beginning of use, the cover 4 is first opened upward from the front side about the hinge 9 so that the top surface of the cover 4 is in contact with the top surface of the support frame 8.

In this state, pull out the towel tray 3 toward the front as shown in FIGS. 3 and 17. At this time, the shafts 93 and 95 are connected to the elongated hole 9.
4 and rotate it while pulling it up slightly so as to pull it out from the bent part 94a of No. 4.

Then, the shaft 93 moves along the long hole 94, and the shaft 95 is located at the upper end of the long hole 96.

In this state, the cover 91 is opened and the rolled towel 52 is fitted into the housing 50.

Then, the tip of the towel 52 is hung on the upper side of the supply row 553, and then pulled downward and guided to the lower side of the towel tray 3.

At this time, as shown in FIGS. 3 and 17, the taxi driver 18, which has already been lowered to the lower end of the elongated hole 11, is moved by the lever 97 as a result of the towel tray 3 being rotated toward the front. Since the support plate 13 is pulled toward this side via the rotating shaft 12, it is guided to the tip side of the bent portion 11a at the lower end of the elongated hole 11.

The tip of the towel 52 pulled out in this state is passed between the taxi roller 18 and the tension detection roller 36 as shown in FIG.
After wrapping the towel around the towel take-up core 44 several times, the towel roll is pushed down along the long holes 43 formed in the side plates 6, 6 of the main body, and comes into contact with the take-up roller 30. let

After the tip of the towel 52 is attached in this manner, the cover 91 of the towel receiver 3 is closed, and the entire towel receiver 3 is rotated and pushed in.

With this operation, the shaft 93 moves toward the back along the elongated hole 94 and eventually falls into the bent portion 94a, and the shaft 95 also moves to the lower end of the elongated hole 96, completing the positioning of the towel holder 3.

At the same time, the lower end of the support plate 13 is pushed through the lever 97, and the support plate 13 is placed in a vertical position as shown in FIG.

Note that when the towel tray 3 is pulled out to the front, the lower end of the support plate 13 is pulled to the front, so the support frame 8 integrated therewith also rotates in the opposite direction in FIG. The cover 4, which is rotated clockwise and partially overlapped on the support frame 8, is also tilted toward the wall, and the center of gravity of the cover 4 moves rearward, making it easier to attach the towel. There will be no inconvenience such as the cover 4 falling toward the front during operation.

When the support plate 13 is vertical, the taxi roller 18 is inserted into the long hole 1.
It is located at the lower end of the vertical part of 1.

In this state, when the cover 4 on the main body side is rotated toward the front and closed, the inside of the upper surface of the cover 4 is fixed to the upper end of the bent part 6a of the side plate 6 as shown in FIG. When the microswitch 42 is contacted, the device including the electric circuit becomes in a standby state.

At this time, the pulled out towel 52 forms a loop below the channel 111.

After the towel 52 has been loaded in this way and the entire apparatus is in a standby state, the lever 82 is pushed over the hanging towel 52.

ζ, the micro switch 81 turns on and the motor 5
4 is activated, the supply roller 53 begins to rotate, and as a result, the disk 66 also begins to rotate. Then, the supply roller 53 continues until the recess 66a formed in the disk 66 rotates once and the actuator of the microswitch 69 fits into the recess 66a again.
rotates and holds the towel 52 at a certain length J I , for example, 21σ
Send only

This feed length J+ is determined by the gear 60 integrated with the supply roller 53.
It is determined by which of the large and small gears 67 and 68 meshes.

In other words, if the screw 64 is located at the bottom of the figure 7-shaped openings 61 and 62 and on the right side, the support plate 63 is lowered as shown in FIG. 15 and is approaching the side plate 51. The gear 60 and the large gear 67 are meshed with each other, and the rotation of the supply roller 53 is transmitted to the disc 66 at a reduced speed according to the ratio of the gear 60 and the large gear 61.

On the other hand, if the screw 64 is located to the left of the upper end of the 7-shaped opening 61.62, the support plate 63 will be above and away from the side plate 51, as shown in FIG. They are meshed, and the disc 66 rotates at the ratio of the gear 60 and the small gear 68, as described above. Since the large gear 67 and the small gear 68 have different numbers of teeth, the number of revolutions of the supply O-ra 53 during one revolution of the disc 66 changes. In other words, two lengths of the towel 52 can be set.

Then, when the actuator of the microswitch 69 fits into the recess 66a of the disc 66, the motor 54 stops.
The towel delivery is finished.

In this state, a timer (not shown) is activated, and after a certain period of time has elapsed, the motor 20 is activated, and the chain sprocket 14 rotates in a direction to move the metal fitting 17 upward, causing the ladder chain 16 to travel.

As a result, the taxi roller 18 moves up the vertical part of the elongated hole 11, and at this time, the taxi roller 18 hooks the towel 52 located below the tension detection roller 36 and moves up, forming a loop. The towel 52 is moved a predetermined distance J2.
move it upwards.

In this state, the loop has not yet been completely wound.

That is, a small loop exists below the dispensing machine simply by changing from the state shown in FIG. 20 to the state shown in FIG. 21.

When the taxi roller 18 reaches the upper end, the micro switch 28 located on the upper side comes into contact with the metal fitting 17, and the motor 2
0 stops.

At the same time, the winding motor 46 is activated, and the winding roller 30
begins to rotate.

As a result, take-up roller 30 and 11! The winding core 44 that is in frictional contact is rotated and the towel 52 begins to be wound up.

As the towel 52 is wound up, the inner surface of the towel 52 comes into contact with the tip of the lever 87, as shown in FIG. winding is completed.

In this state, as shown in FIG. 22, the towel 52 does not form a loop, so there is little contact between the towel 52 and the outside air, making it extremely sanitary.

Also, since the loop is not visible, it looks good in appearance.

After the loop is wound in this manner, it is ready for normal use.

That is, the user only has to press the lever 82 through the towel 52, and when the lever 82 is pressed, the microswitch 81 is turned on in the same manner as described above, the supply roller 53 is rotated, and the towel 52 is sent out by a predetermined length. Stop.

At the same time, the taxi roller 18 that had been located above
The used towel that had been fed into the dispensing machine begins to descend due to its own weight by a distance 42, that is, the distance between the top and bottom ends of the taxi roller 18, and the towel 52 forms a large loop as shown in FIG. , the part of length J+ of the new towel sent out is used to make it easier to wipe hands.

When the taxi roller 18 reaches the lower limit position, the metal fitting 17 comes into contact with the lower microswitch 29 and the taxi roller stops.

When enough time has elapsed to wipe your hands in this state, the timer goes up from 1 to 1 as described above, the taxi roller 18 rises, the upper micro switch 28 turns on, and the winding starts. The motor 46 is activated to wind up the used towel, and when the lever 87 is pressed, the motor 46 is stopped and the towel 52 is completely wound up into a loop.

Thereafter, use is continued by repeating the same operations.

By the way, the towel 52 sent out in the above-mentioned usage state is wound up after a certain period of time, but if the towel 52 starts being rolled up before the user uses it for some reason, the user hastily removes the used towel part. There is a movement of grasping with the hand and trying to prevent it from being rolled up.

Then, a downward force is applied to the taxi roller 18, causing the taxi roller 18 to stop.

In this state, the vicinity of the upper end of the towel 52 is in contact with the lower side of the tension detection roller 36, so when the towel is pulled downward, the tension detection roller 36 is pulled upward along the elongated hole 37. As a result, the rotating plate 34 integrated with the tension detection roller 36 rotates clockwise around the screw 35 as shown in FIG. 23, and the other end of the rotating plate 34 separates from the microswitch 41.

As a result, the motor 20 stops and no overload is applied to the motor 20.

Further, when the taxi roller 18 has finished moving to the upper limit, the motor 20 for the taxi roller 1B is stopped and only the take-up roller 30 is rotating, but even in this case, the microswitch 41 is turned off. Therefore, the motor 46 is safe without overloading the stopped motor 4G.

Note that when the rolled towel 52 runs out and the rear end of the towel 52 hangs behind the dispensing machine 1 without forming a loop, the taxi roller 18 moves upward as described above. After that, the take-up roller 30 is rotated to take up the towel 52, but at this time, no force is applied to the lever 87, so the take-up roller 30 continues to rotate for a predetermined period of time, and then is automatically stopped by a timer and the towel 52 is taken up. The ends are completely wound.

On the other hand, when the number of unused towels becomes small during use, the diameter of the towel 52 already wound around the winding core 44 becomes large as shown in FIG. 30, the winding core 44 moves upward in the inclined elongated hole 43 and turns on the microswitch 45.

As a result, current flows through the light emitting diode and the warning lamp 102
lights up to warn you that you are running low on unused towels.

As a warning means, not only a lamp such as a light emitting diode but also a sound such as a buzzer may be used.

By the way, the use of the towel 52 is not necessarily carried out in an orderly manner after the loop is wound.
While the lever 82 forms a loop and stops, the next user may press the lever 82 again.

Then, the supply roller 53 immediately starts rotating and feeds out the unused towel a predetermined length.

At the same time, the take-up roller 30 also rotates at the same rotation time as the supply roller 53, and winds up the used towel by the same length as the unused towel that has been fed out, so that the towel can be used continuously. I can do it.

At this time, the taxi roller 18 is not activated and the towel 52 is
remains a long loop for ease of use.

The supply roller 53 and the take-up roller 30 are designed to have the same diameter and rotation speed so that they can be used continuously.

On the other hand, if you try to pull out the unused towel part located on the front side by hand without pressing the lever 82, as in the manual towel distribution line, the supply roller 53 has a leaf spring as shown in FIG. The supply roller 53 is connected to the motor 54 through a one-way clutch consisting of 72, and even if the motor 54 is stopped, the supply roller 53 can easily rotate in the direction of pulling out the towel and send out the towel. machine 5
5 can be prevented from being damaged, and the force of trying to pull down the dispensing machine itself, which is fixed to the wall, is alleviated by sending out the towel, preventing it from falling off, eliminating the risk of injury to the user. It is something.

As is clear from the above description, according to the present invention, since a structure in which a one-way clutch is provided on the supply roller side is adopted, the supply roller can rotate in the towel withdrawal direction even when the motor is stopped. Even if the user accidentally pulls the towel when the motor is stopped, the supply roller rotates accordingly and feeds out the towel, so there is no overload on the motor, the motor is not damaged, and the dispensing machine is pulled downward. The force exerted by the towel is also alleviated as the towel is fed out, providing an excellent effect of protecting the motor, etc. and the dispensing machine.
