A sensor for monitoring the movement of a paper reads out the operation of a user for pulling out the paper or stopping the pulling operation. A control program is started by a signal from the sensor and the roll paper feeder performs cutting or feeding of paper automatically. Consequently, the user is not required to operate any switch. The roll paper feeder reads out the intension of the user accurately through movement of the paper. Even a person having one handicapped arm, an infant, an aged person or a person deprived of one's eyesight can pull out and cut a roll paper, e.g. a toilet paper, a cooking paper or a paper towel, readily in safety with one hand.

Description

The roll web feedway

Technical field

The present invention relates to a kind of roll web feedway, it makes disabled user, for example single armed person, blind person or the old or children can extract paper easily out from paper roll (for example toilet roll, napkin paper roll or paper towel roll), and can use a hand to cut or cut off paper safely.And, the present invention relates to a kind of roll web feedway, it need not painstakingly to be handled with one or more switches by the user.

Background technology

In the application of the paper container in usually being widely used in using the paper of paper roll, the user is with the container cover that has blade or cutting edge under the one hand, and catch the paper end with its another hand, then firmly the pull paper to utilize the blade cuts paper.Such a series of actions needs the user to make with the hands simultaneously, and this requires great effort very much for hand, the handicapped personage of eyesight or the old and children.Therefore, for this difficulty is reduced to lighter, proposed and commerce used a kind of paper container, wherein the lid with cutter sweep has interpolation annex thereon, spring for example, thereby the cutting edge of lid can flexibly be pressed against on the paper roll by an active force, and wherein this active force can not arrive greatly to hinder and extract paper out so that an available hand is extracted out and the cutting paper.Yet, even so, unless direction of paper being extracted out and speed and direction, speed and strength that paper extracts suitably regulated in order to cut paper, otherwise can not extract out or the cutting paper on fault-free ground.Yet, at first, do not consider whether the lid with cutting edge has spring or similar device, under any circumstance, the hidden side of cutting edge and invisible is stayed in the paper end that is retained in the paper roll side after paper is cut.For this reason, next user needs at first to extract out at paper with hand to rotate paper roll can see and touch the paper end to this user degree on the direction.Then, this user need use finger and the nail paper end of tearing, and wherein this paper end is depressed and sticks on the paper roll apace when being cut.For eyesight relatively poor or as blind as a bat and lose an arm and the finger of the flexible arm of another has been subjected to hinder and tying up the personage of bandage, this operation is a difficulty very.

In order to solve these inconveniences, in the patent application of being announced in recent years, occurred more and more relating to manually or electronic control automatic reel feeder.Though the applicant was not meeting any automatic reel feeder the day of present patent application by specific and commercialization, had following element usually by the automatic reel feeder known to these patent applications openly.These elements are: the paper container that is used for rotatable support paper roll, the automatic paper supply arrangement, the supply length conditioning equipment, the supply length selector switch, the automatic paper cutting equipment, be used to hold the parts of the paper that is cut and separates from paper roll, be used for after cutting, supplying with the automatic paper supply arrangement of a length paper, be used for starting respectively the switch of these devices, be used for control module at each these equipment of program lower-pilot of setting up in advance, in order to guarantee the sensor of these control module failure-free operations, in order to guarantee the timer of these control module failure-free operations, be used to hold the housing main body of these devices and unit, and the lid that is used for the open space of this shell.These are primary elements of known automatic reel feeder.Being disclosed in the invention of being announced and the many inventions in the application for registration and utility model reconfigures these primary elements, make improvements respectively, design their layout and mounting means, design their control and programming mode, and some elements are combined with these primary elements to attempt to eliminate the deficiency of existing invention and utility model.Yet, many this type of the invention and utility model stayed many need improvements in detail and be difficult to significantly actually the realization.

Particularly, the obstacle as in the reality use has to relate to the problem that has switch.In the past all inventions and utility model all need user's master cock, for example standard button switch or floor push, or infrared detector or sensing switch, at this, extremely amblyopia or personage as blind as a bat will extremely difficultly find the position of switch and understand its function, say nothing of and handle these switches respectively to be embodied as the difference in functionality that these switches distribute.Equally, because the using method of accustomed paper container and this quasi-tradition automatic reel feeder is different in the past, when certain day suddenly replaces with the automatic reel feeder with the paper container of being accustomed to, the notice that then needs to be used to explain the operation indication of its method of operating is attached near new equipment self or its somewhere, but become very faint and can not read the old that operation is indicated for people visually impaired or its eyesight, this can only cause further not convenient.And these operation indications also are the elusive contents of children usually, thereby and any this type of to need the automatic reel feeder of master cock or a plurality of switches inevitable also be that children are difficult to admit.In addition, even for the people of slight amentia, consider " if how? do some things? does will is it pressed and make some things occur? " even the switch that then only exists needs to handle also may bring inconvenient sensation.This user can imagine to obtain, even can not push a switch and may not know how to use it fully.

Summary of the invention

Therefore, the object of the present invention is to provide a kind of roll web feedway, this device makes Any user, for example single armed user or user visually impaired, an available hand is extracted paper easily out from paper roll, cut this paper then safely, and can read user's wish, and need not subconsciously to handle with one or more switches by the user by the motion of paper.

Roll web feedway according to the present invention is characterised in that it can understand user's wish by the motion of paper.Thereby, roll web feedway according to the present invention need not subconsciously to be handled with one or more switches by the user, so the user can extract paper easily out and can cut or cut off paper safely from paper roll (for example, toilet roll, napkin paper roll or paper towel roll).The specific one or more switches that do not had necessary manipulation unlike prior art, according to roll web feedway of the present invention can the personage of obstacle be arranged by physiology or psychology, owing to have only personage, children or child, the old or the blind person of single armed, even be accustomed to and also use easily when first the use without any the mode of incompatibility sensation by the past such as injury.Equally, in roll web feedway according to the present invention, paper is not as being supplied with fully by motor-driven in the known automatic reel feeder or distribute, and can be distributed the paper of about 10cm length by motor-driven in one embodiment.Then,, in the time interval that the paper of this length is drawn out of, do not have consumed power if the user extracts the paper of 1m to 2m length out at all, mean energy resource consumption be reduced to prior art energy resource consumption about 1/10 or littler.Thereby, if commercialization of the present invention is the free-standing roll web feedway product by dry cell power supply, be converted into concept of time, the dry cell that then is used for this product will be than being used for the time that dry cell according to identical time of the automatic reel feeder product of prior art continues to be about 10 times.Thereby needing still less, the remarkable energy-saving benefit that increases of the automatic reel feeder according to the present invention of energy consumption is clearly.

Show as being designed to safe and trouble-free scroll feeder of the invention process with its perspective view among Fig. 1.The shell 1 that forms the main body of roll web feedway has pair of brackets 2a and 2b, and this is to rotatably supporting paper roll or paper web on the support; The outlet 4 of cutting edge in automatic paper cutter or the cutter sweep; Pair of locking projection 7a and 7b, each projection comprises a spring; And dispose a driven roller 3 at the automatic paper supply that is used for after paper is cut supplying with or distributes the certain-length paper or distributing equipment or distributor; A pair of paper pressing device or

press presser feet

5a and 5b is as the annex of automatic cutting device; And a sensor 6, be used to the paper that reads or respond to beginning and stop to move.The lid 8 that can raise to open space in the main body that paper roll wherein is set disposes: sensor is accepted or driven rolls 9, is used for normal control pick-up 6; Passive or driven rolls 10 is used for normally handling the paper distributing equipment; And pair of locking groove 11a and 11b, so that lid 8 is matched with locking projection 7a and 7b in the main body when fulcrum 12a and 12b go to its closed position.Fig. 1 illustrates and is shown in an open position to allow to be provided with the lid 8 of paper roll.In state shown in Figure 1, support 2a and 2b inwardly are supported for outstanding and this moment, they can not admit paper roll from main body inner wall.Support 2a and 2b be designed to the push type ball pen in the same, they are inwardly outstanding together when being pushed from the outside, they are contracted when being pushed again.Thereby, for paper roll being set and being placed on by support 2a and the rotatably supported state of 2b, support 2a and 2b can be from main body inner wall withdrawal once so that paper roll be receivable in the space between them and utilize the centre bore of paper roll or the core tube aligns with them paper roll is set, and they can protrude into the core tube of paper roll then.

Fig. 2 is schematic construction and an explanatory diagrammatic sketch of implementing the roll web feedway of Fig. 1 of the present invention, and it illustrates the roll web feedway, and this device is provided with paper roll, and its lid is positioned at the closed position and paper end 60 is slightly outwards outstanding from the lower end of feedway.For the ease of showing, the bottom of feedway is shown as in Fig. 2 than the bottom among Fig. 1 vertically extends slightly.Corresponding among the Reference numeral that uses among Fig. 2 and Fig. 1.

To specify step, the operation of these devices and the unit of forming the equipment of these steps of the device that use implements below.

Paper roll is set

(1) lid is raised to its open position and paper roll is set, thereby this paper roll is suspended on support 2a and the 2b.Then, be positioned at the paper that is derived from this volume in its vertical-path and make its end expose from the lower end of housing main body and the length of the 3cm to 8cm that dangles.

Close this device

(2) can change following this lid then to its closed position.

(3) at this, if the state that in this Design of device this lid is fully closed is defined as this state, promptly on the paper sheet thickness direction wherein dangle any gap that the paper end passes through of guiding have and make that paper can freely through width (more than or equal to 0.5mm) and prevent that the child from pointing the width (being less than or equal to 3.0mm) that enters, and just can guarantee the functional and security of this device.

(4) when lid is closed fully, sensor 13 inductions that are included in the housing main body provide a signal by the magnetic force that the magnet 58 that comprises in the lid applies with the power control unit to unlatching first power switch, thus the power supply of the electronic system in device.This structure guaranteed when and during just at uncap, each actuation unit in the device or equipment become outage and close and keep outage and close, thereby guarantee the security when replacing paper roll.As substituting of magnet and inductor combination, also can use combining of the high projection of the power switch that is configured in the housing main body and 6mm on the lid.Main switch can be positioned on the sunken inside place of the opening that gets out in the housing main body, thereby the projection on lid just can be opened this switch when being pressed on this main switch.Make this opening enough little and (for example, 3mm) guarantee enough securities in order to avoid child's finger enters.

After (5) first power switches were opened, the sensor 6 that moves that is used to respond to the paper that is drawn out of became effectively with other equipment and unit.In the embodiment shown in Fig. 2, sensor 6 normally rotates decoding formula sensor, and paper is directed between sensor 6 and sensor reception roller 9.

Begin to extract out paper and clamp lid

Paper outlet

(7) when beginning to extract paper out with hand, sensor 6 reads or responds to the paper that begins to move.

(8) sensor 6 outputs can activate the signal of the control module in the safe unit to open the second source switch.

(9) after second switch is unlocked, lid for example is clamped in to electromagnetic force its latched position.For this lid of security purpose keeps locking or clamps until finishing following sequence of operations.At this, one specific, roughly the simplest electromagnetic locking mode is to use electromagnet or similar device, can be thereby prevented to manufacture as utilizing spring freely to give prominence to and the clamping projection 7a and the 7b that withdraw move backward in conjunction with Fig. 1 is described.At this, in the automatic dispensing device of the paper that is derived from paper roll,, then be the most dangerous if lid is opened or insert finger by paper outlet portion when the paper cutting equipment is handled to outstanding sharp cutting edge forward.Thereby, at least up to finishing cutting operation in the housing main body by cutting edge is retracted to, lid need keep locking or clamp, and on the paper sheet thickness direction, need width with paper outlet portion keep enough for a short time (particularly 3mm or littler) enter to prevent that the child from pointing.

The user stops to extract out paper

(10) extracted the user of Len req paper or stop to extract out paper fully out, perhaps temporarily stopped extracting paper out and when being not content with this length, restart to extract out paper and when the length that is met, stop to extract out paper fully.

(11) then, sensor 6 operation is to read or to respond to the paper that stops to move.Sensor 6 has a control module, the identification " stopping " fully if this control module for example was programmed to stop to continue more than or equal to 0.5 second.Then, only continue to interrupt not being considered to " stopping " less than any extraction of 0.3 second, but " not making decision " or " temporarily stopping " and make sensor 6 work on and wait for " stopping " fully.

The cycling of automatic paper cutting equipment

Fig. 3 is the schematic construction and the explanatory diagrammatic sketch of sensor and automatic paper distribution system, and this sensor and automatic paper distribution system are omitted so that the cycling of the automatic paper cutting equipment that has the paper pressing device to be shown by part.Catch the finger of paper end to be shown as and stop to extract out paper.

(12) sensor 6 operations transfer to its control module so that paper is moved " stopping ", thereby the paper pressing device 5a of auxiliary cutting and 5b are outstanding from housing main body 1, so that as shown in Figure 3, paper clamp is held between the inwall and pressing

device

5a, 5b of lid 8.At this, pressing

device

5a and 5b are connected the rear end of cutting edge 17 respectively by compression spring 16a and 16b.When motor 59 beginning with decelerator on the direction of arrow 19 during swing pinion 18, the cutting edge 17 that has with the tooth bar of gear 18 engagement is moved toward lid 8 with its pedestal as one, so that

pressing device

5a and 5b are at first outstanding and cause they and paper strong bonded then from housing main body 1.At this moment, the top no show paper of cutting edge.When motor 58 continued swing pinion 18 on the direction of arrow 19,

compression spring

16a and 16b were compressed, and utilize pressing

device

5a and 5b firm grip paper.It should be noted that at this

paper pressing device

5a and 5b are preferably its paper contact surface and are formed by the elastomeric material with a plurality of little non-slip process.

(13) on the direction of arrow 19, further during swing pinion 18, reach state as shown in Figure 4, thereby paper is cut limit 17 cuttings and is completely severed when motor 59.Motor 59 is preferably that have can be according to the motor of the decelerator of the speed swing pinion 18 that is suitable for cutting, and also dispose the angular sensor that is used to read motor shaft, therefore it can read it respectively corresponding to the cutting edge position, angle of position forward and backward, thereby determines these positions, angle.Forward and the backward position of cutting edge also can utilize a structure to come simple and determine effectively, and this structure is for having a projection on the cutting edge therein, as representing that cutting edge can read by a pair of micro switch the position of the projection of position forward and backward.

(14) when paper is cut and be cut off, cutting edge 17 and

paper pressing device

5a and 5b return state shown in Figure 5 via state shown in Figure 3.On the other hand, when

paper pressing device

5a and 5b unclamped the paper firm grip, the paper of a length of cutting off and leaving from housing main body from paper roll was stayed user's hand.Except the paper end that is derived from paper roll be positioned at (promptly at housing main body) near the electrotome, cut paper end and avoid being pointed catch or contact, the state of the equipment that Fig. 5 shows is identical with state shown in Figure 2.The front and back sliding plate that has elongated hole by use combines with the disk that has circular projection, also can move forward and backward cutting edge according to known manner, thereby the once rotation with disk of circular projection just makes cutting edge single forward in service and mobile backward.JP PH05-111442A illustrated a kind of utilize usually this configuration come mobile ripple cutter with the cutting paper technology.Also can use a kind of like this known technology, the fixedly cutting edge that promptly is connected in lid be installed in housing main body on and the rotation cutting edge that rotates by motor or cam combine, to cut paper as scissors or powerful cutting blade.These technology are described in detail in JP P H10-14811A, and JP PH09-206237A is among JP P H04-20340B and the JP UM H06-19693A.Help the perforation line that cuts if used roll web has, then can read this perforation line to determine its position and cutting edge is accurately orientated as and definite aligned in position with optical pickocff.In the case, cutting edge need not sharp metal edges, and can be the plastic plate that approaches, and the sharp edges of this plastic plate is to a certain degree but can not damage.Utilization is clamped in the opposite side of perforation line on the paper securely as the paper pressing device of the annex of cutting and thin plate is combined with paper along perforation line, can be enough to cut and cut off this paper.Then, even the malfunctioning once in a while and lid of safe unit is opened when making cutting edge outstanding, the user also can avoid the injury of the marginal portion of non-cutting edge.In addition, use the paper roll that has perforation line to make and allow to use electrotome, draw back by opposite side and tear, and cut without cutting edge with perforation line.It is known reading the position of perforation line and stop the method for paper supply and draw back the method for tearing by the opposite side with perforation line by optical pickocff, and it has detailed description in JP P2000-515273A and JP P H11-244189A.

The do action of automatic paper distributing equipment

(15) be returned its initial position when opening paper path when the automatic paper cutting equipment finishes its cycling and

paper pressing device

5a and 5b, the automatic paper distributing equipment is started working.

(16) the automatic paper distributing equipment is programmed with the paper that distributes selected length in its control module and stops to distribute paper subsequently, thereby and operation it stops distribution when the paper of selected length has been assigned with.From housing main body dangle the end of paper of 3cm to 8cm length be confirmed as suitable and selected.This control module is known, simple and effective, and it uses timer to indicate the paper of selected length to be assigned with.

Return original state

(17) signal that finishes its cycling when expression automatic paper distributing equipment is sent by its control module, controller in the safety means mutually should signal, unclamping when paper begins to be drawn out of, thereby allow uncap 8 so that under the situation of needs, freely change paper roll with regard to blocked lid 8.

Other embodiment of the present invention will be described below.

The device that is used for rotatably supporting paper roll can be different to have and uses the support 2a of paper roll core tube and the device of 2b as shown in fig. 1.It can be the device shown in Fig. 6 and 7, wherein utilize

sheet support

20 and 21 from the following paper roll that rotatably supports, one of sheet support 21 can be the part of sheet support roller 22, this backing roll 22 is installed as and makes paper to extract out from paper roll smoothly as shown in the figure, another 20 also can be the same section of another backing roll, yet, since these backing rolls not necessarily, so one of them or all also can be omitted.

For the sensor of the paper that is used to read beginning and stops to move, can in the multiple choices of its type and installation method, select.

Read at sensor under the situation of rotation

Support 2a shown in Fig. 1 or 2b can have this type of sensor that reads the rotation of paper roll core tube.If the rotating shaft of the sheet support roller 22 among Fig. 6 has this sensor, this also is effective.In addition, the rotating shaft of driven roller 3 or driven rolls 10 can have this type of sensor, with the paper that reads beginning and stop to move.

Under sensor is situation to the photodetector of light transmission response

As shown in Figure 6, the light that sends from transmitter 23 penetrates the paper of being made by fiber and enters photodetection sensor 25 as arrow 24 indications.When paper begins when mobile, the state of the paper fibre before the sensor changes, and changes the ray density that the gap that penetrates paper fibre enters photodetection sensor 25.Photodetection sensor 25 sends corresponding to the signal of the ray density of its reception and this signal and is transferred to control module.This control module judges that paper is moving as long as the signal of its reception is changing, and the response unchanged signal in back and judge that paper stops fully at interval at the fixed time.

Be under the situation of photodetector of response light reflection at sensor

As shown in Figure 7, the light that sends from transmitter 26 as arrow 27 indications, advance and as the surface of the paper made by fiber like that of arrow 28 indications reflect the light inlet electrical resistivity survey survey sensor 29 of going forward side by side.When paper begins when mobile, the state of the paper fibre before the sensor changes, and changes the ray density that is entered photodetector sensing 29 by the surface reflection of paper fibre.Photodetection sensor 29 sends corresponding to the signal of the ray density of its reception and this signal and is transferred to control module.This control module judges that paper is moving as long as the signal of its reception is changing, and the response unchanged signal in back and judge that paper stops fully at interval at the fixed time.Even have minute movement that any this type of sensor of sensor identical function level used in the image sensing mouse with personal computer can read paper fully and it stops.

Fig. 8 is schematic construction and the explanatory diagrammatic sketch that improved embodiment is shown, and the lid 8 that wherein is used for opening Fig. 1 main body is divided into loam cake 30 and lower cover 32 in the position that sensor driven rolls 9 is gone up slightly.Loam cake 30 is configured to it and can be unlocked like that opening the space it under by arrow 31 indication, thereby feasible paper roll can be set therein, and the lower cover 32 that holds sensor driven rolls 9 and driven rolls 10 is configured to it and can laterally opens.This is not dispose support 2a and 2b rotatably to support one of possible embodiment of this paper roll with the core tube that uses paper roll.Lower cover 32 utilizes vertical hinge 33 to be connected in housing main body 34, it can be gone to open position and closed position around this hinge, and disposes lock hook 35 for this lower cover.But this lock hook 35 also with dashed lines shows to represent that when this lower cover 32 is closed it is used for the position of reference.This loam cake 30 is also configurable a lock hook 36, and disposes locking member 37 and following locking member 38 in the wall within it for this housing main body 36 of safety.After as shown in Figure 8 paper roll being set, when user as shown in Figure 9 began on the direction of arrow 39 the pull paper, sensor 9 read moving of the paper that remains between sensor 9 and the sensor driven rolls, sends signal with the control module in safety means.Then, control module in the safety means makes upper and lower covers locking member 37 and 38 move on the direction of arrow 40 and 41 respectively, thereby loam cake and lower cover 30,32 keep clamping, until finishing a series of automatic circulations, i.e. the circulation of automatic paper cutting and distribution after the user stops to extract paper out.When these automatic circulations were finished, the control module in the safety means made upper and lower covers locking member 37 and 38 return its initial position, and if necessary the user can replace paper roll and clear up whole device on this position.In the device shown in Fig. 8 and 9, shown groove 42 is provided as and holds cutting edge therein.

Figure 10 and 11 specifically illustrates according to the embodiment of claim 5 and is cutaway view at this embodiment in the zone of paper outlet portion.With reference to Figure 10, the about 2mm to 3mm in gap between the inwall 43 of housing main body and the inwall 44 of lid, and this lid has outer cover part 45, and this outer cover part 45 has the tilting member 47 that connects thereon via fulcrum 46.If though the width of tilting member 47 greater than paper then this tilting member 47 will better work, if when its during along paper centering its width be too narrow to 3cm to 5cm, it also can fully realize its function.The paper 48 that is distributed by automatic dispensing device is shown as along the inwall 43 of housing main body and the middle road between the inner lid 44 and is folded down naturally.

Figure 11 is illustrated in the state of pull paper 48 on arrow 49 directions.When paper 48 on the direction of arrow 49 during by pull, tilting member 47 is being rotated on the direction of arrow 50 so that sheet metal 51 combines with projection on the sheet metal 52 around fulcrum 46.Sheet metal 51 and contacting of sheet metal 52 make flows through trigger current in the whole control module of device, it makes the power supply of each other sensor be unlocked and is held so that its work and keep its operation.This also make automatic paper distributing equipment, automatic paper cutting equipment and safety means each control module electric power starting and keep so that they move and keep their operation under program.Thereby as trigger switch, sheet metal 51 and 52 certainly replaces visible on the market micro switch product.For the ease of understanding, trigger switch is shown as the exit region that places paper path in the embodiment of Figure 10 and 11, yet, can directly contact at this area triggering switch with user's finger.The very meticulous and assembling in the following manner usually that this trigger switch is made is even if promptly it moves for paper slight that the finger all responsive and user contacts its any precise part then it may be the inducement of plant failure.Consider that for this some trigger switch preferably is arranged in the paper path a little the position away from its outlet.Then, the inwall 43 of housing main body can partly cave in smooth curved shape, and tilting member 47 partly is out of shape corresponding to this, thereby causes paper to dangle by gravity in this curved shape, and paper can pass through by between (gap with 2mm to 3mm) simultaneously.Though trigger switch is very sensitive, can be set to so little gravity not being produced reaction.When the user wanted to extract paper out under this state, the paper that is entered the smooth curved shape by gravity generation distortion was strained and forces subsequently the tilting member 47 of projection to return by the tension force straight line, thereby makes sheet metal 51 electrically contact with sheet metal 52.

Other possibility forms for trigger switch will illustrate a specific embodiment below, and this embodiment adopts the switch that utilizes centrifugal force.Figure 12 illustrate paper 53 be placed between driven roller 3 among Fig. 1 and 2 and the driven rolls 10 and on the direction of arrow 54 by the state of pull.Following moving of paper 53 for the axle configuration one-way clutch of driven roller 3 so that driven roller 3 can not be subjected to the influence of motor 14 and power conveyer belt 15 rotates.Be connected in the gear 55 and pinion 56 engagements of driven roller 3, so that accelerating transmission gear to be provided, even and the eccentric switch 57 that is connected in the axle of pinion 56 can obtain the slight mobile of enough big torque and response paper 53 and be unlocked.Trigger current flows into its control module from eccentric switch, with to each other sensors power supply, with turn on sensor and be held so that its work and keep its operation.This also makes the power supply of each control module of automatic paper distributing equipment, automatic paper cutting equipment and safety means be unlocked and is held so that they move and keep their operation under program.The trigger switch that Figure 10 and the equipment shown in 12 are worked equally is can be by using permanent magnet to produce electrical the contact indirectly manufactured to come out.Eccentric switch is that known internal structure is just enough in some lightening toys.

Also is effective by using bevel gear flatly to rotate eccentric switch for the sensitivity that improves sensor.In addition, there is the conventional eccentric switch of spring, weight and electric contact different, can uses switch by the mercury of Metal Ball charging with mounted inside.As mentioned above, the use of trigger switch is at first moved and is adjusted to when paper begins to be drawn out of and moves, the power supply that is used to read or respond to the sensor of the paper that begins and stop to move with unlatching, thereby make sensor at first work, this provides power savings, so that the energy consumption of idle roll web feedway is entirely zero.Then, this and other sensors of being activated with electrical control appliance are held "on" position subsequently, monitor unchangeably continuing.If light stimulus or electricity or physical stimulus are applied on each sensor, the control module that then is connected in this sensor relatively applies the state before and after the excitation and reads between the two variation, with operation and control connection under preset program in the work of each equipment of this type of control module.

Thereby, in free-standing roll web feedway will be provided in the time will being used as the dry cell power supply of the limited energy, it also is uneconomic at all promptly using little electric current to make sensor keep energising in one day 24 hours at this, and the use of trigger switch has improved energy-saving efficiency extremely effectively.Certainly, if be that this roll web feedway is prepared private home power supply, undoubtedly can use standard electric, light or the physical sensors of one day 24 hours continued power of needs in the position (for example toilet) that the roll web feedway is installed.Though show and illustrated the trigger switch of some forms in conjunction with Figure 11 and 12, and the possible mode of wherein powering to the sensor that adopts trigger switch, but term " trigger switch " is not any other things of expression as used herein, but a kind of sensor, this sensor physical detection or moving in response to paper, should move when after the user catches the paper end, beginning to extract paper out, to produce this signal of telecommunication that moves of indication.To be illustrated as the program that control module response moves from the signal of sensor (comprising trigger switch) below, this sensor reads a kind of state, and paper begins to be drawn out of from moving in this state, distributes and cutting equipment with the circular flow automatic paper.Though known automatic paper distributes and cutter sweep needs switch on its surface, button form switch for example, to start its operation, but the present invention is designed to omit and cancels this type of outside switch of installing of the prior art and (comprises any near switch as such as the substitute of the switch of button, thereby the user can be seen), replace and adopt sensor (comprising trigger switch), this Sensor Design is for responding to user intention by moving of paper of monitoring, to move response and start this device from the required cycling of the signal of sensor by starting a program.Start and move this class method and make the automatic paper distributing equipment to move by the paper that distribution is set at the length that is suitable for using, move the automatic paper cutting equipment by the cutting paper then, and the automatic paper distributing equipment reruns by distributing paper to a certain extent subsequently, this degree is to be suitable for the user to be folded down from paper outlet portion with the paper of pointing the length of catching, promptly arrives the part that initially begins of recovering this circulation and extracts paper out to wait for next user.Thereby, even have only for various reasons the user under the situation of single armed and also can use this equipment, catch the paper end securely and begin to be assigned with the Shi Yaoyong finger at paper unlike prior art, therefore antihygienic situation that may occur in the prior art can not appear, in the prior art, do not caught and finally fall on the floor opening paper that the paper that is forced to distribute behind the switch is cut and is cut suddenly in user's hand by the user.It should be noted that the trigger switch that constitutes aforesaid sensor can place any position of paper path or place with roll web moves on corresponding any of rotating.The outside known automatic reel paper that starting switch is installed is supplied with and cutter sweep is used by the single armed person if having, then (maybe ultrared during near on-off effect when utilizing) paper must begin to force automatically immediately to distribute when switch is pressed, and needs the user to utilize a quick-moving speed of push switch to catch the paper end.Yet in the time of might working as the user and attempt to grasp, the paper of given length is assigned with already and cuts, and falls on the floor then, if the user is physiology or psychological handicapped person, this situation probably takes place.In addition, if the blind person uses the automatic reel paper according to prior art to distribute and cutter sweep, matter of utmost importance whether have starting switch with and wherein, and same conceivable in a period of time at the beginning of grasping paper neatly this device will can not work well, unless exist something to catch this paper.According to the present invention and since only after the user has caught the paper end securely and has begun to extract paper out this device just can bring into operation, thereby can not run into this type of difficulty.

Thereby, can use according to novel roll web feedway of the present invention according to the impression identical with the traditional paper container that uses custom already as user's blind person.In addition, need not presentation switch (not the button of pushing by vision indication and not by the vision indication so that hand approaching near switch) and need not to use indication, if the paper container of for these people they being accustomed to already at home in certain day replaces with according to this novel roll web feedway of the present invention suddenly, this device can very successfully be introduced into, this user without any unconformable sensation, except they may only feel this paper container some thing be updated.Use the user of this roll web feedway may have one or two time in surprise in " paper has come out therefrom ", but, will no longer be felt confused and rapidly the use of this device will be had acceptance if paper cuts him automatically because he has caught the paper end with its extraction and notice that paper is assigned with.

Because how the present invention relates generally to sensor installation reading or to respond to beginning and the paper that stops to move and handled among other problems in it is implemented, so will omit detailed description further to power supply, wiring, electronic control system, eccentric switch etc.Be worth being understood that the present invention is not limited to the embodiment and its embodiment that have illustrated and can changes according to the distortion and the different of their mounting means of element.For example, the embodiment shown in Fig. 8 and 9 can change into and remove loam cake 30 and the loam cake locking member 37 with lock hook 36, so that distortion to be provided, is referred to as to be out of shape A.It has omitted lid and device for locking cover, and they are configured to the security of assurance device and make its fault-free.Omit therein among the distortion A of lid, user's hand can contact and depress paper roll when paper just is assigned with.So, if the draft of distributing equipment is greater than strength of paper then can be from the paper roll paper of tearing.Perhaps, can apply excessive load to distributing equipment, the durability of this distributing equipment is not enough good and repeats to apply that this load may cause the destruction of gear and distribution rollers be may wear to that paper can not be distributed well and/or motor and circuit board heating and lost efficacy to a certain degree.Thereby this distortion makes this device incomplete aspect globality and possible fault elimination, but it will be useful product, it can be by the reduction cost with the price listing that reduces, if and gone bad also and can buy again, thereby it still has new valuable commercial opportunity for the consumer market.

The application example of distortion A will be described below--use A, this distortion A is installed under the paper container of installing already in the toilet therein.In being different from the existing paper container of the embodiment shown in Fig. 8 and 9, by its core tube of axial support paper roll is set, thereby this paper roll can be around its axle rotation.Thereby, use among the A at this, by using existing paper container one roll web is set so, extract out paper longer then so that paper can be grasped by distortion A.Paper will be extended a yardstick, thereby its end will arrive position shown in Figure 8.Do like this is in order to make the user have gentle hands to change places the extraction paper can cut this paper safely.Along with lock hook 35 combines with locking member 38 to prevent that lower cover 32 is opened, can prevent that cutting edge is exposed and protects the user to escape injury, thereby just guarantee security.Though existence may cause the worry that the paper roll of fault may be touched and push, this is bad like that in this way.Be designed to accurately to read user intention and making available hand extract out among the present invention that paper can be cut then automatically, can comprise such as lid, cover lock element and be used for rotatably supporting the element of the device of paper roll, so that this device is easy to use, safety, fault-free and quality are good, but these elements are not complete necessary element.In using A, the user need not to pull down and abandon the existing paper container of having installed, and only needs to buy and install by omitting the product that some parts have reduced the distortion A of price.From low spending, leicht fallen D/A with produce the viewpoint of refuse less, be considered to become and be suitable for common and than the people of low income level and be suitable for the embodiment of environment at incomplete distortion A aspect its integrality and the durability.Reading of the moment that paper is therein begun to be drawn out of will accurately be read the wish or the hope of user " beginning to extract out paper now "; And paper therein stopped reading of moment of being drawn out of, will accurately read near the wish or the hope of user " because length is enough herein cutting paper ".In the present invention, if if only user's hand near or paper only contacted slightly, then will not allow this device to bring into operation.At first and and if only if paper has been booked and judge " user has extracted paper out or needed a piece of paper " when beginning to be drawn out of.By moving of monitoring paper, this device accurately reads user's wish.Being not intended to extract out any of paper makes the approaching action of installing or slightly contact paper of hand not be regarded as the action that needs a piece of paper to carry out.Thereby, the invention provides a kind of roll web feedway, it can move after accurately reading user intention.
