Abstract

PURPOSE: To provide a rolled towel dispenser of making possible to use one driving motor to draw out or roll towel cloth by composing of that the cycle of drawing out a small quantity of a towel is started by the action of reversible motor and after a predetermined time is elapsed, an externally hung down towel cloth is rolled. CONSTITUTION: When the output axis 61 of motor M is rotated clockwise for example, its output is only transmitted to an axis 63, therefore, it means that only transmitted to an axis 25, in contrast other axes 73 and 35 are stopped. On the other hand when the output axis 61 is rotated counterclockwise, the above relation ship becomes reversible. When a button 41 is pushed, a motor M is rotated toward the driving direction of rough surface roll 25 and a towel cloth drawn out from a sending roll 32 is passed through sandwiched portion between rolls 25 and 27, and is further drawn out by passing through a slit 19 between projecting reed shaped tips 12a and 13a. After a predetermined time is elapsed, the motor M is rotated toward reverse direction, a drawn out towel 2 is continuously rolled by the axis 35 of a roll 33 until the towel cloth is stretched around a reed shaped element 15 and then the small region of towel is made possible to touch from the outside.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an improved electronically controlled dispenser for dispensing towel pieces from a roll of towel cloth. It has excellent hygienic characteristics and has a simpler structure compared to American dispensing devices.

[Conventional technology and problems]

Continuous towel dispensers currently in production and installed in premises for sanitary services in offices, factories, schools, public facilities, etc. may have manual controls or electronic or electric controls with push button operation. It has characteristics common to Tsubamekudan Taizo.

This common custom feature is that the dirty towel fabric comes out through the front of the dispenser, and the dirty used towel fabric connects to the back of the temporary dispenser with a relatively large loop outside the dispenser. Based on the configuration to return, there is one. The path that the towel fabric follows inside the dispenser is relatively complex and somewhat similar across all types of dispensers, with clean towel fabric being fed out, running from a feed roll placed at the bottom of the dispenser, and then being rolled up onto a top roll. Ends up with used towel fabric.

Although the material used to make a fully continuous towel is a cotton-based fabric, the terms ``towel'' and ``fabric'' used hereinafter mostly refer to other materials with similar properties, such as types of specialty paper. It also applies to

As a general trend in the above-mentioned American technology, it is impossible to guarantee that the length of the fabric that the user pulls down with a manually operated machine is clean, as the gripping part of the fabric is necessarily in a position where it can be used. Therefore, it has many deficiencies, mainly in terms of hygiene. For dispensers with electronic drive and push-button control,
Constant contact with the outside surface of the dispenser is necessary.

In the case of American phosphoric acid, there is always the possibility that complete separation between the clean and dirty rolls will not be achieved, which is a hygiene hazard since the dirty towel take-up roll is above the clean roll. This is essentially due to the complicated path that the fabric takes. Between these, the feed roll is constructed so that it can wind up the end portion of the towel iIk during nitrogen (IJ) - this configuration prevents excessive soiling of at least the final length of the towel, but it also adds to the complexity of the internal structure. However, the problem is not solved satisfactorily.

In addition, various attempts have been made to solve the problem caused by the presence of external loops in the towel fabric, such as winding up the loop f' each time the towel is used. However, instead of staying there, a certain length of cloth remains under the dispenser in a more or less tense state and is relatively easily visible and can be cleaned from the outside of the dispenser, causing it to become dirty. It is even more prone to contamination as it exits the bottom of the dispenser due to constant contact with the fabric. When the user pulls the fabric in a manual dispenser or a semi-manual electronic dispenser, the newly formed loop wraps around the fabric in such a way that the front side near the user is clean and the back side is dirty. There is a waiting period for it to be taken. As is clear from the foregoing, all American dispensers are not suitable for proper dispensing of fabrics in situations where maximum hygiene is required, as the above-mentioned disadvantages negate the benefits of sterilizing fabrics. I can't say it's a thing. Italian patent application engineer T-22198A/
Although use of the solution described in 86 does ensure v# production, this method increases the complexity of the dispenser due to the use of extra equipment in the dispenser and additional operational complexity.

A helpful solution to the technical problems described above is Irish patent publication no. It will be done. However, if a certain length of material remains to be accessed from the outside, even if this length is less than the equivalent length in the solution mentioned at the outset, the construction from Figure 6 of the above-mentioned Aisle 2Pg patent application is possible. As you can clearly see, this is not something that can be ignored. Furthermore,
Even in the case of this dispenser based on American technology, the clean towel feeding roll must be placed at a position below the position of the used towel winding roll.
The two passages are not kept clearly separated by the fixing element. Furthermore, the basic characteristics of the dispenser described above as described in the above-mentioned Light Row patent application cause each length of the towel loop to be generally aligned with the user and thus perpendicular to a wall or other support structure. Finally, this dispenser is a crude 8 degree S construction which assumes the need for a separate ringing member for unwinding and reeling the towel fabric.

[Purpose and structure of the invention]

The object of the invention is to ensure all the required hygiene while at the same time allowing the use of a single drive motor for both the unrolling and winding of the towel fabric as required. The aim is to provide an easy-to-roll towel dispenser both in terms of the number of mechanisms involved and the structure.

The CV waiting ridge of the invention provides an optional ridge which is received in a compartment separate from the mechanical drive member and which is suitable for very easy removal and replacement when necessary, without the need to provide access to the inner cavity of the dispenser itself. A dispenser structure is obtained in which electronic control components are provided.

The rolled towel dispenser obtained by the present invention includes:
A rear support suitable for mounting to a wall is provided, a center separator element secured to the rear support, and top and bottom covers pivoted to the rear support, the center separator and cover being arranged in an overlapping manner that is pulled apart from each other. Two partitions are formed together, the top partition is suitable for accommodating the first feed 9c1-le of clean towel fabric so that it can lie freely horizontally, and the bottom partition 9M is suitable for accommodating the first feed 9c1 of clean towel fabric so that it can lie freely in the horizontal direction. It accommodates a motor-driven shaft for winding onto the second roll, both ends of which are rotatably attached to the two connection plates of the housing, and the towel fabric is attached to the first
The passage from the 1ltlSlk to the 2nd c2-r is followed by a rough-faced drive roll driven by a motor from the same opening as the winding shaft, and the two ends are rotatably housed in the 1ltlSlk part plate. A pressure roll is mounted on the top cover element for elastic pressure contact with the towel fabric placed within the top partition 9 and in contact with the coarse drive roll, the towel fabric then being able to project forward and outwardly. After passing around a portion of the separator, the fabric enters the bottom compartment and is wound onto the winding shaft, the top and bottom cover elements each having an outwardly projecting lip at the end furthest from the pivot. However, in the open vILVC, the protruding portion of the separator element is machined so that it is almost surrounded in a tongue-like manner between the two lip-like portions of the cover with slotted holes between the layered portions, and the rough surface sliding roll is formed. Then, after a predetermined time delay, the entire towel fabric suspended outside the dispenser during use is wound up by actuation of a reversible motor suitable for driving the said winding shaft. A control push button is provided to initiate the cycle of dispensing, and the fabric enters and exits the dispenser via the #1 slot.

According to other features of the invention, the length of the towel fabric to be dispensed is specific to the motor rotational speed and the adjustable time delay between dispensing and winding up of the towel fabric; Various safety checks regarding occlusion of the cover element, continuous detection of the presence or absence of towel fabric σ to abort the operation when the towel fabric is used up, and activation if there is a lie:'if object to prevent excessive dispensing of the fabric. The actuation cycle of the dispenser is initiated by a suitable a-thick device which moves said motor in either direction as a function of reference information relating to protection circuits etc. for aborting the cycle; According to another v) feature of the invention, the a-thick device includes a Kth memory circuit for re-establishing the aborted operating cycle upon termination of an obstruction to proper dispensing. The power supply consists of the motor and gears installed in the blockage box, the electronic parts that make up the logic device, and the power supply device driven by the battery and main line drive, all of which are mounted on a single printed circuit board. fjcvIjL, etc. are stored, and this box also contains piece 11 of the dispenser housing.
1iiiHc) A shaft for driving a rough drive roll in the top partition and a winding shaft in the bottom partition is fixed in the protruding opening.

This configuration allows mechanical parts to be removed from the shaft by the motor WkwJ so that they can be repaired or replaced independently, as opposed to electronic parts that can be replaced after the printed circuit board has been disconnected. It also applies. In order to improve the functionality and modular customization of this device, /) Some plates on the left and right sides of the I7 song are held in place by spring tightening to prevent corrosion and reduce wrinkles. To avoid processing costs, each part may preferably be made of resin, allowing the song itself to be disassembled.

According to the very important%1lkVC of the present invention, both 11 of the separation tongue elements around which the loops of towel fabric are formed.
The 4M (D protruding lip piece) can be placed in close proximity to the towel so that it cannot be accessed from outside the dispenser when the dispenser is not in use. A very short path of clean fabric through each is protected from any possible contamination.

[Implementation row]

At the turn, the dispenser IKI construction, the supporting rear structure 11, which can be attached to the wall in the usual way,
A housing 10 comprising a central separator partition 914 formed by two opposite walls 14a and 14b with concave surfaces oriented upwardly and downwardly, respectively.
is provided.

A curved top cover 12 is attached to the top end of the support 11.
', and the bottom end is a curved bottom cover 13 at the same (d!).
The covers are pivoted at 13' to meet at the front of the device when closed, as will be described in more detail below. The housing 10&C also includes two four-part roots 16 and 1T assembled by elastic spring tightening.

When the two covers are closed, a top partition 22 is formed inside the curved portion 14aK of the separation I114'#, while the bottom partition 2 is formed by another curved portion 14b.
3 is formed, and the two compartments are completely separated from each other. A downwardly inclined planar portion 15 is provided fixed to the housing 10 and forming a front external extension of the partition 14.

The top and bottom covers 12 and 13 are provided with outwardly protruding inclined surface portions 12a and 13a, which form "lips".
12a and 13a are "tongue-shaped" portions 15 that can protrude outward;
It extends outward by at least the same length as the ``tongue'' and constitutes a single lip on both sides of the ``tongue''. Therefore, when the top cover 12 is lowered and the bottom cover 13 is raised and placed in the closed position, the "tongue" portion 15 of the inclined plane is completely enclosed between the "lips". The "tongue-shaped body" 15 does not come out from the slotted hole 19 that meets the outside.
'.

When the top cover is lifted, the IC is easy to attach the roll 32 to the top compartment 22. roll 3
2 & forms a supply reel of towel cloth 2 for wiping workers' hands. This roll is simply placed on the curved bottom wall of the top compartment 22, whereas the dirty cloth winding roll 33 housed in the bottom compartment 9 23 winds up the used towel around a shaft 35. placed for. axis 35
is rotatably attached to plates 16 and 17 of the housing, and one end of the shaft (11 in the figure)
A drive mechanism driven by a motor M is provided at the end 1fls)K near the plate 16. The other end of the shaft (close to the plate 1T) is equipped with an elastic device 39 such as a coil spring or the like #137 provided on the plate 17 that keeps the shaft 35 mechanically engaged with the other end at all times.
#IV
c It is stored.

The path followed by the towel fabric 2 from the feed roll 32 to the take-up roll 33 is clearly shown in FIG. Reference numeral 25 denotes a drive roll having a rough surface (for example, coated with sand vapor), and the roll 27 preferably presses the rubber material coating onto the inside of the front part of the top cover 12 together with a spring 29 that presses the rough surface drive roll 25. Installed.

The feeding of the towel 2 from the roll 32 is controlled by the rollers 25&c, and the roll 25 is driven at one end (particularly the same end as the drive end of the shaft 35) by the same motor M in the dispenser as described below. In the dispenser, there is no roll or escape route for the towel strip 2, but it simply slides downward and forward on the PFI diagonal "tongue" 15 between the protruding lips 12a and 13acv. A very wide or flat sheet of two closely spaced parallel sheets is then passed through the same slot 19 to the outside, before the towel returns into the dispenser again through the same slot 19. A shaped towel loop is rolled out of the dispenser, but in this case of return, it passes under the separation tongue and is finally wound up by the roller 33. In this way, the tongue element 15 Top partition 9 rooms 2
2 and the bottom partition presentation 23 constitutes an external extension of the separating partition.

In this way, the slotted hole 19 is linear and the separating tongue 1
5 (The outer ends of lJ are retracted from the outwardly projecting lips 12a and 13a, so that when the dispenser is not in use, it is retracted into the dispenser and pulled around the edges of the tongues, as will be described in detail later.) It is ensured that it is practically impossible to make contact with the portion of the towel that is exposed.

The dispenser according to the invention includes an improvement over the original path for towel strip material in that a clean towel feed roll is placed above a used or soiled towel take-up roll. Furthermore, the dispenser is suitable for electronic control, providing additional advantages as outlined in section a of the Preface. In this point,
The intermediate portion of the separation tongue 15 includes a touch sensitive area, such as a movable push button 41, which conveniently engages the microswitch 43 as appropriate. This pushbutton 41
The protruding lip-like piece 12a of the top cover in the touch-sensitive area is provided with notches 45 on its four outer edges, and the button 41 is configured to be actuated by the user's finger. As the towel 2 is fed along the tongue 15, contact in this area (which is the only area of the towel accessible from outside the dispenser) ensures that the towel is clean and air-resistant. yP Patent Application No. 323/85, etc., without positioning the control towel under the towel to be soiled with dirty or wet hands.

The microswitch moves the motor M in the direction corresponding to the drive of the rough-surfaced pivot roll 25, so that a predetermined length of the towel 2 that remains outside is exposed to the user, as shown in Figure 812. It is especially unrolled so that it can be used as a two-layer towel, since the front and back of the unrolled fabric are completely clean. isi [After a predetermined time delay set by the timer T, the motor moves in the opposite direction and enters the previous operation, and the entire towel 2 that is fed out outside the dispenser is wound up inside the dispenser and the tongue element 150 Around this, the shaft 35 is driven under tension and tension 1 so that only a small area of the towel occupying the touch-sensitive area 41 is kept accessible from the outside by creating a notch 45, thereby allowing the dispenser to open. 9 rudders to start a new working cycle. The slotted aperture 19 is wide enough to pass two layers of fabric, while at the same time allowing the fabric to be held taut on the outer edge of the tongue element 15 as described above. Preferably, books are also prevented from coming into contact with the fabric.

After the fabric is re-spooled, it can be used to improve cycle reliability by utilizing the tension in the fabric as a protection against possible erroneous 1JtlVc.

Tension can be used in the form of an additional enablement signal by the inlet electronic circuitry which is sent to the control logic device described in more detail with respect to FIG. For now, when the fabric 2&ede is unwound into the dispenser, the fabric extends into the two parallel ribs 48 and 4B& of the bottom lip 13a and this groove + row Vc and is rotatably attached to the end plate of the dispenser. Suffice it to say that the arm 49 on the stump axle 51 forces it to follow a figure-eight path between the intermediate rocker element 47 and the intermediate rocker element 47 .

The spring 53 continually urges the rocker 47 downward so that the rocker is fully lowered only when the fabric has passed the a-pick and there is no tension on the dishcloth.

Thus, the lack of tension and therefore the presence of free loops of the fabric 2 becomes a mounting condition for the start of the fabric winding, and if the user carefully keeps the fabric externally taut, the winding is prevented. be done. A storage device is suitably provided to ensure that the original conditions are re-established even after the dispenser has been switched off.

One important purpose of the second device for sensing the tension in the fabric 2 is to detect the tightness of the roll and perform the end-of-cycle sequence, after which the dispenser is switched off. In such a situation, the micro switch 43&c may be configured to turn on the motor MK in order to drive the roll 25 and unwind a predetermined length of fabric only when the rocker element 47 detects the tension determined by the fabric winding during the previous cycle. can. This means that the next length of fabric cannot be unwound until the previously unwound length has been properly wound up. As mentioned above, the separable closure box provided in the housing 100 pieces @ 2
0, a power supply block A constituted by an electronic circuit fiL providing a control logic device and a power supply device driven by a battery or main line;
A reversible DC motor M and a mechanism for appropriately transmitting driving force to the shafts 25 and 35 are provided, and although the mechanism is not shown in FIG. 1, it is shown separately in FIG. The box 20 also contains, of course, each meter required between the power supply block A and the motor M and the electronic board, as shown schematically in FIG. 5 together with indicator lamps R and V.
Connections are also included.

In FIG. 4, the output shaft 61 of the motor M is connected via an ordinary one-way coupling device to a shaft 63 fixedly mounted without a worm gear 64 meshing with an ear 65 mounted coaxially with the roll 25. There is. An ear 11 is also fixedly provided on the drive shaft 61, and this ear is connected to a pair of other ears 71a and 71bj! A warm ear 74 is fixedly connected to the shaft T3 via a second unidirectional connector T2, and is wound around the shaft 73 and meshes with an ear 75 disposed coaxially with the shaft 35. . The unidirectional couplings 62 and T2 are designed to rotate their driven parts, i.e., shafts 63 and 73, only when the drive shaft 61 rotates in a certain direction, i.e., if the drive shafts are aligned, they rotate in a clockwise direction. In this case, the driving force is transmitted only to the shaft 25 according to the shaft 63, while the shafts 13 and 35 are stationary, and the opposite is true when the drive shaft rotates counterclockwise or clockwise. . Therefore, by simply reversing the force supplied to the motor M, the IJT rudder is used to cause the shaft 25 to pay out the fabric or to rotate the shaft 35 to wind up the fabric while keeping the other shafts stationary. . It goes without saying that other known means may be used to achieve the same effect without departing from the scope of the present invention.

The electronic control device system is explained by the block mV in FIG.
) is sent to the power supply Al via a safety microswitch C activated by opening the covers 12 and 13. Assuming that the cover is actually closed, the power supply A1 powers the motor M via the single-acting circuit P under the control of the output from the factory A1, and also the logic device and the corresponding memory and It also powers the protection circuit OPM. The logic device is constructed in the form of a single board @&C and, as already mentioned, is responsible not only for the power supplied by A1, but also for the signals from the circuit OPM, the signals from the cycle start microswitch 43 and the cycle completion or Human power for a signal from the locker 47 indicating that the fabric is used up (or, more preferably, the required mechanical tension is lacking in the fabric)? have. Furthermore, a control pulse is sent to the device by #11 timer T to determine when to start winding the fabric, and the number of rotations performed by the motor is set to the well-known qj! : In the area (in progress if lined up) A signal is sent by the photo reflector fixed at 6111 and the adjustment device RL
This ensures that the set length of fabric is actually unrolled. In this way, the length of the towel available outside the dispenser can be adjusted. After all of this input data has been processed, an appropriate control signal is output by the Elsic device, causing the drive circuit P to apply power of the appropriate polarity to the motor (whether the motor rotates in the unwinding direction or rewinding direction). (by either rotating in the direction)
, delivering power for an appropriate amount of time. The red and green light emitting diodes R and L indicate the operating state of the dispenser 1.
1. Suitable visual indications are provided in the usual manner, such as for example when the fabric is out or when the cover position detection contact 0 is in the open position and the battery status that can be shown on the OB.

As is clear from the above explanation, open the cover on the bottom of the dispenser 1, place a new roll in the top partition (12 above the Da section), let it roll out from the bottom of the fabric roll, and roll the fabric into a tongue-like shape. Wind the fabric into the dispenser by passing it over the top surface of the body 15. Remove the fabric by moving the spring 39 so that the end of the shaft 35cv can slide along #37&C. The dispenser is easily loaded by winding it onto the shaft 35 in the bottom compartment. After closing both covers, which are preferably made of transparent material (at least for the top cover), the dispenser is ready for operation. Therefore, it is not necessary to pass the fabric between rolls or between rolls or between sheets, and the dispenser loading operation can be completely performed from the front of the dispenser. .

Given the highly hygienic and custom-made premise of the dispenser according to the invention, a hermetically closed refill containing a sterilizing roll that is unwound through a slotted hole χ that opens when the dispenser is refilled. Reloading is performed by nl
This makes it possible to impart desired sterile properties to the fabric fed out during the working cycle LJ)yB.

Those skilled in the art will be able to make additions and/or modifications to the IM sequence of the present invention as described and illustrated above without departing from the scope of the invention 911. In particular, various control means for controlling unwinding and winding are provided on the shaft, and it is ensured that the fabric follows a path through and out of the front of the dispenser and back to it.
