Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a towel dispensing machine, and more particularly to a towel dispensing machine configured to allow used towels to be extremely easily fed out and retracted from the bottom of the towel dispensing machine. It's about giving opportunities.

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

In conventional towel dispensing machines of this type, the towels form a loop at the bottom of the dispenser and hang down, but if the loop is always formed, it looks unsightly. Not only that, but the towels are also extremely unhygienic as there is dirt attached to them.

Therefore, a towel dispensing machine has been proposed that automatically winds up the loop part after a certain period of time has passed after the towel has been used.

However, in conventional towel dispensing machines of this type, the mechanism for winding up towels and eliminating loops is extremely complicated, and the loops must be formed large during use, making it difficult to dispose of used towels. The towel must be fed out again, making the mechanism even more complicated, and the towel feeding and feeding movements also become unnatural.

The present invention has been made to eliminate the above-mentioned drawbacks of the conventional towels, and uses a taxi roller that is raised and lowered by an endless chain to allow towels to be fed and fed in very easily. The purpose is to provide a towel dispensing machine.

Hereinafter, details of the present invention will be explained based on embodiments shown in the drawings.

Incidentally, a shaft 93 is protruded from approximately the center of the outer surface of the left and right side plates 51 of the housing 50, and this shaft 93 slides into a long hole 94 formed in the side plates 6, 6 on the side of the device main body. They are movably fitted. Long hole 94
The innermost end thereof forms a bent portion 94a toward the lower end.

Further, a shaft 95 is protruded from the lower ends of the outer surfaces of the side plates 51, 51 in a state opposite to the shaft 93, and this shaft 95 is located at the lower end of the side plates 6, 6 on the main body side, and extends from the bent portion 94a. It is fitted into an elongated hole 96 that is elongated in the vertical direction and is formed facing the .

Incidentally, one end of a lever 97 is rotatably connected to each outer end of the shaft 93, and the other end of the lever 97 is rotatably connected to the frame 13b at the lower end of the support plate 13. There is.

On the other hand, the mounting plate 5 has an upper plate 98 as shown in FIG.
and a lower plate 99. The upper plate 98 is formed as a horizontally long quadrilateral plate, and the lower plate 99
is formed as a vertically elongated quadrilateral plate, and both are rotatably connected via a shaft 100.

The upper end of the upper plate 98 is folded back to form a bent portion 98a, and a stepped pin 101 is fixed to pass through the center of the upper end of the upper plate 98, including this bent portion. This stepped pin 101 is fitted into a keyhole-shaped opening 7a formed at the upper end of the back wall of the frame 7 on the apparatus main body side.

This upper plate 98 is completely fixed to the wall surface with screws or the like.

On the other hand, at the lower end of the lower plate 99, an arcuate bent portion 99a is formed outwardly and upwardly.
This bent portion 99a serves to receive the lower end of the back wall of the device body.

Note that one end of a warning lamp 102 made of a light emitting diode or the like fixed to the support plate 13 is located in a 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. As will be described later, when the remaining amount of unused towels is low, the lamp will light up to prompt you to replace the towels.

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

When starting use, first remove cover 4 and hinge 9.
The cover 4 is opened upward from the front side with the top of the support frame 8 in contact with the top 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 shaft 93 and the long hole 94 are pulled up slightly and rotated so as to be pulled out from the bent portion 94a of the elongated hole 94.

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 roller 53, 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 roller 18, which has been lowered in advance at the lower end of the elongated hole 11, is moved to the support plate via the lever 97 as a result of the towel tray 3 being rotated toward the front. 13 is the rotating shaft 12
Since it is pulled toward the front side through the elongated hole 11, it is guided to the tip side of the bent portion 11a at the lower end of the elongated hole 11.

In this state, the tip of the towel 52 pulled out is
As shown in the figure, the towel is passed between the taxi roller 18 and the tension detection roller 36, guided to the rear and upper side of the fixed shaft 31a located near the take-up roller 30, and wound around the towel take-up core 44 multiple times. The winding core is pushed down along the long holes 43 formed in the side plates 6, 6 of the main body, and brought into contact with the winding roller 30.

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

Due to this operation, the shaft 93 moves to the back side along the long hole 94, and eventually falls into the bent part 94a, and the shaft 95
is also moved to the lower end of the elongated hole 96, and the positioning of the towel tray 3 is completed.

At the same time, the lower end of the support plate 13 is pushed via the lever 97, and the support plate 13 becomes vertical as shown in the 18th line.

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 is also aligned with the rotating shaft 12.
The cover 4, which is partially overlapped on the support frame 8 by being rotated counterclockwise in FIG.
The center of gravity of the cover 4 moves rearward, and the inconvenience that the cover 4 falls to the front side during the towel mounting operation does not occur.

When the support plate 13 becomes vertical, the taxi roller 18
is located at the lower end of the vertical portion of the elongated hole 11.

In this state, when the cover 4 on the main body side is rotated toward the front side and closed, the inside of the top surface of the cover 4 becomes a micro switch fixed to the upper end of the bent part 6a of the side plate 6, as shown in FIG. 42, the device, including its electrical circuit, goes into a standby state.

At this time, the pulled out towel 52 forms a loop below the dispensing machine 1.

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

Then, the micro switch 81 turns on,
The motor 54 is activated and the supply roller 53 begins to rotate, and as a result, the disk 66 also begins to rotate. and,
The recess 66a formed in the disk 66 rotates once, and the actuator of the micro switch 69 moves into the recess 6 again.
The supply roller 53 rotates until it fits into the towel 6a and delivers the towel 52 by a certain length l ₁ , for example, 21 cm.

This delivery length l ₁ is determined by whether the gear 60 integrated with the supply roller 53 is engaged with either the large or small gear 67 or 68.

That is, if there is a screw 64 at the bottom and right side of the Z-shaped openings 61 and 62, the support plate 63 is lowered as shown in FIG.
Since the gear 60 and the large gear 67 are close to each other, the gear 60 and the large gear 67 are engaged 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 67.

On the other hand, if the screw 64 is located to the left of the upper end of the Z-shaped openings 61 and 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 rotations of the supply roller 53 during one rotation of the disk 66 changes. In other words, two lengths of the towel 52 can be set.

Then, the actuator of the micro switch 69 is inserted into the recess 66a of the disc 66.
4 stops, and the towel feeding ends.

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 1. At this time, the taxi roller 18 hooks the towel 52 located below the tension detection roller 36 and moves upward, forming a loop of the towel. 52 upward by a predetermined distance _l2 .

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 at the upper end comes into contact with the metal fitting 17, and the motor 20 stops.

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

As a result, the take-up core 44, which is in frictional contact with the take-up roller 30, is rotated and the towel 52 begins to be wound up.

Then, as the towel 52 is wound up, the towel 5
The inner surface of the lever 87 touches the tip of the lever 87 as shown in FIG.
6 is turned on, rotation of the motor 46 is stopped, and winding of the towel is completed.

In this state, the towel 52 is
Since the towel 52 does not form a loop, there is little contact between the towel 52 and the outside air, making it extremely hygienic.

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 presses the lever 8 through the towel 52.
2, and when the lever 82 is pressed, the micro switch 81 is turned on in the same way as described above.
The supply roller 53 rotates and the towel 52 is sent out by a predetermined length and then stopped.

At the same time, the taxi roller 18, which had been positioned above, begins to descend and the used towels that had been fed into the dispensing machine are moved to _l2 , that is, the taxi roller 18.
The towel 52 hangs down due to its own weight by the distance between the upper and lower ends of the towel 52, forming a large loop as shown in FIG. 20, making it easy to wipe hands using the portion of length _l1 of the new towel sent out.

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

In this state, when enough time has passed to wipe your hands, the timer counts up as described above, the taxi roller 18 rises, and when the upper micro switch 28 turns on, the winding motor 46 starts. When the lever 87 is activated and the used towel is wound up, the motor 46 is stopped and the towel 5 is rolled up.
At No. 2, the loop is completely wound.

Thereafter, use is continued by repeating the same operation.

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 micro switch 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 18 is stopped and only the take-up roller 30 is rotating, but even in this case, the micro switch 41 is turned off. The motor 46 is safe without overloading the stopped motor 46.

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 and the towel 2 is wound up, but since no force is applied to the lever 87 at this time, 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 2 is wound up. The end of 52 is fully 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 micro switch 45.

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

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 performed in an orderly manner after the loop is wound up, and the next user may press the lever 82 again while the towel 52 is forming a loop and stopping. A pressing condition occurs.

Then, the supply roller 53 immediately starts rotating and feeds out the unused towel for 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. Can be done.

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

The supply roller 53 and the take-up roller 30 have the same diameter and the same rotation speed so that they can be used continuously in this manner.

On the other hand, if you try to pull out the unused towel portion located on the front side by hand without pressing the lever 82, as in a manual towel dispensing machine, the supply roller 5
3 is connected to the motor 54 through a one-way clutch consisting of a leaf spring 72 as shown in FIG. Since the towel can be sent out, damage to the motor 54 and reducer 55 can be prevented, and the force that would try to pull down the dispensing machine itself, which is fixed to the wall, is alleviated by sending out the towel, so that it falls off. This eliminates the risk of injury to the user.

As is clear from the above description, according to the present invention, endless chains are arranged along the vertical direction on the left and right rear sides of the frame that constitutes the device main body, and a taxi roller is placed horizontally between these sets of chains. A structure is adopted in which the part of the used towel that is wound up on the take-up core is hooked to this taxi roller, so the used towel can be efficiently loaded and unwound by moving the taxi roller up and down. The towel can be easily used due to its simple structure.
