Description

[Detailed description of the invention]

[Industrial Field of Application 1 The industrial field of application of the present invention is to construct a towel so that winding and feeding of towels can be carried out extremely accurately.
This is the field of route routing equipment. [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 used glue. In the conventional towel dispensing machine of this scale, the beam A hangs down in a loop below the dispensing machine, but if the loop is always formed, it looks unsightly. Not only that, but there were 11 towels with trash, etc., making it extremely unusable.
I am a qj student. Therefore, an IM-built 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. [Problems to be solved by the invention] Towels cannot be hung around in the glue A-role distribution machine having such a structure! A taxi roller is provided on the elevator 7, and by raising and lowering the taxi roller, used towels are fed out to form a loop below the device, and used towels are stored. I demonstrate the loop! The robot performs the following actions. However, since users are not familiar with the structure, they may end up pulling the used towels while they are being stored. In this case, an extremely large force is applied to the taxi rollers, resulting in damage to the device. [Means for solving the problems] In the present invention, in order to solve the problems mentioned above,
Taxi with towels raised next to each other

[
The rotating frame is installed so that it can be raised and lowered freely, and the rotating frame is tilted by the tension applied to the taxi roller, and this tilting actuates a switch, which stops the rotation of the motor and causes the taxi roller to move up and down. A safety device has been adopted to stop the vehicle from moving. [Function] By adopting such a safety device, if an undesirable tension is applied to the towel, the motor will be stopped and the taxi roller will stop running. damage to the equipment can be prevented. [Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings. The wiring device 1 is attached to the main body 2 of the device, and there is a rotating white stone on the lower front side of the device main body 2. Installed so that it can be opened and closed freely. It consists of a cover 4 that can cover the front of the distribution machine 1, and a mounting plate 5 for attaching the main body of the distribution machine to a wall or the like. The details of each part will be explained below. The main body 2 has a frame 8 with a cross section of [ ] 11, which is open on the front side and has a frame 8 that is open on the front side and has a frame 8 that is open on the left and right side plates 6, 6, etc. with the face plate 1. Rotating frames 9 and 10 are arranged at closer positions. Each pivot frame 9,10 is formed as a vertical frame. The upper end of one rotating frame 9 is wide and has a cross section of
A letter-shaped bent portion 11 is formed outward. Also, on the front side edge of this rotating frame 9, there is a “C” facing outward.
A bent portion 9a is formed over almost the entire length. A "1-1" 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 12 is formed by bending a band-shaped metal plate with a stepped bent part at 90 degrees from the middle, and one end 12d of this frame 12 meets the wide band part 9C at the lower end of the rotating frame 9. A shaft 13 is horizontally suspended between them.As shown in FIG. A chain sprocket 14 is rotatably supported on this shaft 13 between the frame 12 and the wide part at the lower end of the rotating frame 9. One end of a shaft 15 is fixed to a bent portion 12a in the middle of the body 12, and the other end of this shaft 15 projects in the direction of a bent portion 9b at the lower end of the rotating frame 9. 15 is wound with a spring 16, and this spring 16 is in a state of being elastically loaded between the bent portions 91) and 12. Therefore, the bent portions 12a and 9b are moved far apart 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. In addition, a long hole 17 is formed at the lower end of the side root 6 in correspondence with the long hole 12b, and the long hole 121) and 17 are provided with a shaft 1.
8 is slidably fitted from the outside of the frame 12 and is fixed to the side plate of the slider receiver 3, which will be described later. A state in which the two sliding plates 19, 19 penetrating the base of the bent portion 9a (7) formed on the side edge of the rotating frame 9 are slidably perpendicular to the axial direction of the rotating frame 9. It has been installed. A pin 20 that serves as a stopper is provided at the front end of the sliding plate 19 so as to protrude from 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 slidably through the base 1 of the four-shaped bent part 21. A cross section arranged parallel to the rotating frame 9 at the beyond position is fixed to a bent portion of an elongated "U"-shaped support frame 22. 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 frames 9 and 10.・Furthermore, a spring 24 is stretched between the bending piece 21 and the sliding member 19, and the friction member 23 moves backward.
It gives you the power to. The reference numeral 25'c (-0) is a screw that fixes the spring 24 to the sliding plate 19 side.
The other end of 4 is fixed to a protruding piece 21a that is cut and raised from the bent piece 21. In the above structure, the friction member 23 is attached to the rotating frames 9 and 10.
This figure shows the mechanism that causes forced rotation due to friction with the taxi rollers, which will be covered later! I can do it. However, taxis [forced rotation for 1-ra! The 1M construction is not limited to this mechanism, but the rear end edge of the rotating frame 9゜10 is formed wide rearward to the position where it contacts the taxi roller, and the rear end edge itself or this The rubber-like part L installed on the rear edge J becomes the friction member 23, and the taxi
[A mechanism that forcibly rotates the retaxis roller at the same time due to the contact friction force during the 1-L lowering can also be used. Further, the upper end of the rotating frame 9 has a "1-" shaped bent part 110.
The base portion is rotatably supported by a pin 26 protruding from the outer surface of the upper end of the side plate 6. The position of the pin 26 serving as the pivot of the rotation frames 9, 10 is determined by the position of the taxi-ra 38 (described later) installed in the rotation frames 9, 10.
The installation is at position 1 on the horizontally front side from position 1, and due to this eccentricity, the taxi roller 38 is rotated around by the taxi roller 38, and the taxi roller 38 is biased by the force that pushes it downward. For tracing, the rotation frames 9, 10
pivots around the pin 26 so that its lower end swings toward the front. Upon this rotation, a switch S5, which will be described later, is turned on and the motor drive is stopped. 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. , 10 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. In other words, at the -1 end of the rotating frame 10! A supporting J31 frame 27 with an 11 character [ ] open toward the L31 outside is integrally formed, and a bent portion 10a is formed at the front side edge of the rotating frame 10 toward the outside. A bent portion 10b is formed on the front side of the lower end. Also, along the outer edge of this bent portion 101), the frame body 1
A frame body 12 having the same m structure as 2 is arranged in a symmetrical state, and a shaft 13 is horizontally suspended between the rear end of this frame body 12 and the lower end of the rotating frame 10. The outer end of the frame 13 is slidably fitted into an elongated hole 13a formed at the rear end of the frame 12. A chain sprocket 14 is also rotatably supported on this shaft 13. Further, a shaft 15 is similarly fixed at one end to a bent portion 12a in the middle of the frame 12, and extends in the direction of the other end t of the shaft 15 and the first bent portion 10b. This shaft 15 has a spring 1
6 is wound, and both the bent portions 12a and 10b are given a force in the direction of moving away from each other. -9= A support frame 22 to which a friction member 23 is fixed is also attached to this rotating frame 10 side. Since its structure and shape are exactly the same as those on the rotating frame 9 side, duplication of explanation is avoided (-
), the same parts or equivalent parts are given the same symbols f(1
I'll omit that explanation. By the way, a long hole 12b is formed in the front end of the frame 12 on the side of the cooperating frame 10 along the axis lj direction, and a long hole 17 is formed in the lower end of the side plate 6 facing each other. It is formed. A shaft 18 is fitted into the elongated holes 121) and 17 from the outside of the frame 12, and is fixed to the side plate of a towel holder [-J3, which will be described later. In addition, near the bending part 12a of the frame body 12 on the rotation frame 10 side [
Furthermore, a limit switch S5 is provided inside the rear half of the frame body 12. This limit switch S5
As will be described later, is a switch for detecting and overturning the rotating state of the rotating frame 1 ( ). Furthermore, a printed circuit board [) on which an electronic circuit for controlling the entire operation is mounted is fixed to the outer surface of the side root 6 on the side of the rotation frame 10. A motor M2 is fixed to the lower end of the rotating frame 10 with its rotating shaft parallel to the axial direction of the rotating frame 10. It is fixed to the output shaft of this motor M2. A

It meshes with an A-arm wheel 28a rotatably supported on the vertical wall of the support frame 27 (see FIG. 9). A gear 29, which is integral with this arm wheel 28a, meshes with a gear 31 fixed to one end of a shaft 30 extending through the vertical wall of the support frame 27. The gear 31 is integrated with the chain sprocket 1 to 32 and the chain sprocket 1 installed at the lower end of the rotating frame 10.
An endless ladder ridge 33 is stretched between the 4 and 4. The other end of the shaft 30 extends through one end of the rotating frame 9, and is connected to the chain sprocket 3 on the outside of the rotating frame 9.

It is rotated around G, but at this time each rotation frame 9, 1
0 and - Body axis 304) is rotated. Therefore, in order not to impede the rotation of the shaft 30, a groove 6b is formed on the back side of one end of the side plate 6.6. 11 of the support plate 35 is fixed to the ground surface of the rear end of the support frame 27 at the upper end of the rotation frame 10, and this support plate 3! ) A switch S3.34 is fixed to the lower end of the ladder chain 33 to turn the direction of the ladder chain 33 to limit 1. Further, the bent portion 11 and the support frame 27 at one end of each rotating frame 9, 10 extend beyond the top end of the side plate 6.6 and face upward by a predetermined distance, and the upper surface of the bent portion 11, 27 A top plate 36 is fixed. The top plate 36 covers the rear of the top end of the frame 8, and bent portions 36a formed at both left and right ends of the top plate 36 are connected to the bent portions 11 and 11 of the rotating frames 9 and 10. i+I i?￥ 1/ on the outside of the support frame 27
ing. By the way, both ends of a taxi roller (storage 1) 38 are fixed to the tU end sides of the side plates 6, 6 of the left and right 111 ladder chains 33, 33 via t, 1 fixing portions 4) 137. The circumferential surface of the taxi holder 38 is covered with a wear part 4A made of rubber or the like, which is fitted into a notch 6C formed along the downward direction on the rear edge of the side plates 6, 6. ing. The lower end of the notch 6C is continuous with the notch 6d facing the front side of each of the side plates 6, 60. Further, when the taxi driver 38 moves one step downward, it comes into contact with a 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-1]-ra 38 are formed to have a smaller cross-sectional diameter than the central portion 38b. Small diameter left and right ends 58a, 3

The circumferential speed J of a and the circumferential speed h of the central part 381) are large, so that the part A that is surrounded by the central part 38b is wound up as soon as possible so that the unrolling operation is carried out as soon as possible. It is done. The friction member 23 is constantly given a force in the direction of contacting the taxi 311 by the tensile force of the spring 24. However, the spring 24 is only provided to ensure the contact between the spring 241 and the spring 24, and if the dimensions of the members are adjusted appropriately, the spring 24 becomes unnecessary. The rear edge of 10 is connected to the friction member 2
If it is 3, then 1, this trailing edge will make the taxi [)
- Both ends 38a, 38a of the roller 38 // It4
They are forcibly rotated through frictional contact, and the central portion 38b is rotated at high speed in the same manner as described 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 spindle 391 of the rotary plate 39 also serves as the spindle of the roller 41 in the first roll. An arc-shaped kite plate 41a is installed behind the winding 11-ra 41 (around the main part Ii)').
It is being A long hole 39a is formed in one end of each rotary plate 39 in the vertical v1'+1 state, and the side plates 6, 6 have a horizontally long Holes 40 are formed. Pins 9d and 10d protrude from the inner surfaces of the respective rotating frames 9 and 10, and are fitted into the elongated holes 39a and 40, respectively. Also, between the lower ends of the co-movement plates 39 and 39, there is an adjustment [1-ra 42].

The I-worm gear 43 fixed to the output shaft is engaged with the A-worm wheel 44 fixed to the outer end of the shaft 391 of the take-up roller 41. Therefore, when the motor M3 rotates, the A-wheat A743 takes up -0 winding via the worm wheel 44 [1-Lar 15
= 41 is rotated 11, and a 1-1-roll-shaped towel can be wound up as described in 1 below. By the way, in the side plate 6.6, a long hole 46 into which a used towel roll @45 is fitted is formed obliquely from above the front side of the side root 6 toward the center of the winding roller 41. ing. The peripheral edge of the elongated hole 46 except for the l end is a bent edge 47 that is inclined and pushed out inward. By forming such a curved edge 47, the long hole 4

It is only necessary to drop the winding shaft 45 into the long hole 46 from the upper end thereof inside the long hole 46, and there is no need for both ends of the winding shaft 45 to protrude to the outside of the side plate 6. Therefore, parts etc. can be effectively arranged on the entire side surface, and the device can be made more compact due to (1) the protrusion of the shaft. Moreover, the bent edge becomes a rib on the side plate, and the direction of the mechanically strong electric current on the side plate can be adjusted. In addition, since this bent edge is wound onto the winding shaft and comes into contact with the end of the used roll,
The frictional force can be significantly reduced compared to the conventional case where the entire side plate of the sea urchin contacts and covers the sea urchin, making winding easier. Furthermore, this bent edge contacts and covers the end of the roll A,
It is possible to control the so-called "takun"-like winding and make the end face flat to achieve beautiful winding. On the other hand, the towel receiving number 3 is constructed as shown in FIG. 5. In other words, the towel tray G-J 3 has the left and right side plates 48.

In this state, if there is still a paper towel A, the process advances to step n15 during the intermediate stage of using the unused towel 70, where the limit switch $4 is turned on, the motor M3 rotates, and the take-up roller 41 is rotated. Winding of the towel The towel is rotated in the h direction, the winding shaft 45 in contact with the towel is rotated together with the towel, and the used towel is wound up (step n16.
n17). When the used towels are collected, the loops of the towels are released and the towels are stretched tightly with a predetermined tension.
Although it is located at the upper end position, a downward force acts on the towel that is being rotated around it, and this acting force simultaneously moves around the bin 26, which is the rotation center of the rotating frames 9 and 10. The frame lower pant is moved downward and forward by -1. As a result of this movement, the limit switch S5 is turned on and the motor M3 is stopped. Step n18. n19), return to step n1,
It will be in standby state for the next use. In order to further ensure this final movement, a shaft (1 in the figure) is installed horizontally at the lower end of the rotating frames 9 and 10, and the towel is rotated around the outside of this shaft from the bottom surface of the main body. Since it is arranged so as to revolve around the lower taxi roller, this shaft moves toward the front side due to the tension of the roller, facilitating the aforementioned movement of the rotating frame 9.10,
To ensure ON operation of limit switch S5. In order to access this shaft, it is sufficient to install the shaft between the chain sprues 1 and 14 and 14 at the lower ends of the rotating frames 9 and 10. On the other hand, in step n14, if there is no towel after the motor M2 has stopped, that is, if there is no towel, the process proceeds to step n20 at the final stage where the limit switch S
4 is on, the motor M3 rotates, but in this case, the limit switch S5 is turned on when there is a towel.
Since it does not turn on, the L-taper M31 continues to rotate.
Noru. However, in this case, as a motor safety device, the rotation time of each motor in the forward and reverse directions is set to a certain period of time, for example 20 seconds, so the towel rotates for a certain period of time and the towel is completely wound up to the end. -(・Motor M3 stops at I (steps n 21, n 22). On the other hand, in the case of continuous use, in other words, the sound of the previous use occurs immediately after wiping hands, and when the used towel is not wound up. A state occurs in which the next user presses the switch board again without starting or ending the device. In this state, as shown in FIG. It is used continuously without any reaction (up to 4 motors). However, after the timer is activated, if the switch plate 63 is pressed in step T1, the motors M1 and M3 start rotating at the same time in step T2. At T3, the supply roller 50 and take-up roller 41 rotate, and at step T4, a new towel is fed out, and a used towel is wound up at equal distances, and then at step n.
The control routine proceeds to step 9 and below. Continuous use is not possible after the routine moves to step [19]. On the other hand, when the lid (J bar) 4 is opened, the following control is performed. When listening to cover 4, there are two cases: when the cover is replaced, and when the cover is opened midway. In either case, the control operation is as shown in FIG. That is, when the cover 4 is heard in step 1 no 1, the limit switch S6 is turned off in step U2,
In step U3, the operations at -C are reset 1 to 1. Subsequently, in step U4, motor M2 starts rotating,
Rough Sea Roller 38/i~Sj Tsubu 1. Start descending at J5. When the taxi roller 38 descends, the limit switch S3 becomes A at step 7 (step 7).
The rotation of motor M2 stops at . In this state, in step t18, replace the door with a new one or check the inside, and then close the cover 4 in step LJ9, and step ()1
At 0, the limit switch S6 goes off. In this state, all functions are restored and the process moves to step n1 and subsequent steps. On the other hand, when a used towel is pulled at the point where it begins to be stored by the taxi roller 38 or the take-up roller 41, a large tensile force is applied to the towel. is the downward tensile force J

, 104, the date movement plates 39, 39 move in an interlocking relationship with the winding roller 41 as a center of rotation so as to move the adjustment roller 42 backward. This adjustment []-ra 42's retreat increases the forward movement of the rotating frame 9.100 by 011,
Adjustment 1] - Due to the synergistic action of the roller 42 and the rotation frames 9 and 10,
As a result, the rotating frames 9 and 10 move forward reliably, and as a result, the limit switch S5 becomes A, and the motor M2

1 Rir. This operation is the operation of the safety mechanism shown in FIG. 12, which functions only when a towel is present. By the way, if you want to replace the controller 0, you will need to pull out the controller number 3. At this point, as described above, all control operations are stopped by listening to the cover 4, but the operation of the controller 3 itself is as follows. That is, Fig. 15 (A), (R) and Fig. 16 (A), (
First, pull the towel holder 3 toward you as shown in B). At this time, the pin 69 is connected to the elongated hole 6 formed in the side plates 6, 6.

When the entire A-ring holder (2) 3 is rotated in the counterclockwise direction in the figure, the pin 69 moves in the arc-shaped part 68b of the elongated hole 68, and the A-ring holder 1 and 3 move to the front side. It is rotated towards the front and opened. As described above, the shaft 18
The frame body 12 is pulled toward the front via the frame 12, and the lower ends of the rotating frames 9 and 10 are also pulled toward the front. As a result, pin 9 (1, 10d
FIG. 15 (△) shows the rotating plate 39 which is interlocked with each other via the elongated hole 39a to move toward the front side. (B), Fig. 16 (A>, (, [3>) shows that the adjustment roller 42 is rotated counterclockwise as shown in (-). As a result, the adjustment roller 42 (moves to the rear of the frame 8). As a result of the rearward movement of the roller 42, the space within the frame 8 is opened, and the towel is not easily attached to the winding shaft 45 when replacing a new towel, or when a taxi [
The operation of turning the latch around the l-ra 38 is extremely easy. After replacing the towel in this way, return the towel = 35- holder 4J 3 to its original state and close the 77 bar 4, the device will return to the state in which it is possible to write a star 1- = l to IC 7-6. However, as shown in FIG. 12, control operations are possible. By the way, the vertical movement of taxi 1]-ra 38 is kT.

Since the towels 70 are forcibly rotated, there is little friction during the storing operation of the towel 70, and it is possible to store the towels 70 smoothly. In addition, as a result of the left and right ends 38a, 38a of the small diameter portion coming into contact with the friction member 23, the circumferential speed of the center portion 38b, which is the large diameter portion, becomes extremely high. It can be done forcefully and quickly. Therefore, the ν~ board (
Illustrated i! Since the gap between the towel and the dorsal root is small, the towel inserted through the gap is folded into the gap due to the contact resistance with the dorsal root, and phenomena such as getting caught do not occur, making it possible to smoothly insert and remove the towel. It is done. In other words, when the taxi roller 38 descends,
The taxi roller 38 feeds out the towel downward and rotates at high speed in one direction, and due to this rotational tension, the towel between the 1-ra and the taxi-ra is under tension, and the taxi roller 311 The towel comes into close contact with the circumferential surface, increasing the frictional force for feeding out the towel and ensuring that the towel is fed out downwards.Therefore, no sagging phenomenon of the towel occurs inside the taxi roller 3Jl. When the towel rises, the towel is sent out from the taxi roller 38 to the adjustment roller at high speed, and in order to avoid reducing the tension of the towel traveling to the take-up roller, the winding torque of the winding "1-ra" is reduced and the winding is carried out at a low load. Effect E] As is clear from the above explanation, according to the present invention, the used glue A is stored by the taxi rollers that move up and down, The roller is mounted on a rotating frame rotatably supported on the upper part of the device body so that it can be raised and lowered, and when towel tension is applied to the taxi roller, the rotating frame is tilted away. !If the towel is pulled while the towel is being stored, the rotation frame is tilted by the tension applied to the towel, and this tilting actuates the switch to stop the rotation of the U1 motor. A towel dispensing machine that does not cause damage due to motor overload, taxi rollers, etc. can be obtained.
