Description

  The present invention relates to a roll paper towel dispenser obtained by winding a belt-shaped paper towel into a roll, and more particularly to a roll paper towel dispenser that automatically discharges a paper towel having a predetermined length from an outlet.

  As shown in FIGS. 8 to 11, in the roll paper towel dispenser X100, a user or the like is detected by a sensor or the like, and the paper towel 120 is fed out from the roll paper 102 that is rotatably supported inside the housing. An automatic paper discharge type is known in which a paper towel 120A having an appropriate length is automatically discharged from a slit-shaped paper discharge port 106 provided in the paper and can be cut. The automatic paper discharge type roll paper towel dispenser is also called an auto dispenser, a hands-free dispenser, or the like.

  In this type of automatic paper discharge type dispenser, as shown in FIG. 9 in particular, a paper towel 120 fed out from a roll 102 by a paper discharge roller 104 and a nip roller 105 provided in the vicinity of a paper discharge port in the housing. The paper discharge roller 104 is rotated by power (not shown) such as a motor to expose the paper towel 120 from the paper discharge port 106.

  On the other hand, since the roll paper towel dispenser is generally installed so that the rear surface of the casing is in contact with the wall W, the paper discharge port 106 is provided in front of the lower portion of the casing. Further, it is assumed that the user grasps the paper towel 120 </ b> A exposed from the paper discharge port 106 by hand and pulls the paper towel 120 </ b> A upward and applies the paper towel to the front edge of the slit-shaped paper discharge port 106 to cut the paper towel. A cutting blade 160 is provided on the front edge side of 106.

  However, in the above cutting operation of the user, the forward pulling is insufficient, and the paper towel 120 </ b> A may not be cut in a straight line along the cutting blade 160. More specifically, for example, when the user is right-handed, the right hand that is the dominant hand grips the right side of the paper towel 120A and then pulls in the left front direction opposite to the dominant hand (Z1 direction in FIG. 8). It is often operated like this. At this time, the right side of the paper towel 120A is first brought into contact with the cutting blade 160 to form a cut that triggers the cutting, and then the paper towel 120A is cut in a straight line along the cutting blade 160. The However, if the user does not sufficiently pull the paper towel 120A in the front direction and pulls the paper towel 120A in the lateral direction as indicated by Z2 in FIG. 8, the paper towel 120A does not sufficiently hit the cutting blade 160 and the paper towel 120A is pulled. It may not be cut cleanly.

  This cutting failure has become more prominent due to the recent downsizing of roll paper towel dispensers. That is, in recent compact roll paper towel dispensers, the distance from the roll 102 to the paper discharge port 106 is short, and the number of guide rollers is small. Therefore, the paper towel from the paper discharge port 106 is not stretched. As a result, as shown in FIG. 9, the paper towel 120 </ b> A exposed from the paper discharge port 106 is slightly curled toward the back side, and the paper towel 120 </ b> A exposed from the paper discharge port 106 is far from the cutting blade 160. There is a tendency. This becomes more prominent as the roll becomes closer to the center. For this reason, the paper towel 120A may not hit the cutting blade 160 during the cutting operation of the paper towel 120A, particularly when the initial cut is formed in the cutting operation. This type of cutting failure is a type in which the paper towel is manually pulled out, and the user also pulls out the paper towel.Therefore, the paper towel may be moved toward the back side by curling because the paper towel is pulled out with a certain amount of tension. Not so noticeable.

  In the automatic paper discharge type dispenser, the problem becomes significant when a cutting failure occurs due to the cutting operation. (1) Since paper towels are stronger than tissue paper, etc., if they are not cut neatly along the cutting blade, they will be torn off as shown in FIG. The paper tends to become wrinkled near either the left or right of the paper discharge roller 104 and the presser roller 105. In addition, wrinkles may occur due to uncut paper towels in the center. If wrinkles approach the cutting edge in this way, the paper towel 120 is not sufficiently held between the paper discharge roller 104 and the presser roller 105, and the paper towel 120 is not fed out at the next forced automatic paper discharge. There is. Further, (2) when the paper towel 120 is torn off, the cutting edge reaches the inside of the case with or without wrinkles, and if it is severe, the clamping position by the paper discharge roller 104 and the pressing roller 105 is set. It will reach the inside of the case. In this case, the paper towel 120 may wrap around the paper discharge roller 104 or the press roller 105, and automatic paper discharge may not be performed and the paper towel 120 may not be fed out. Further, (3) as a result of the paper towel 120 being torn off, the paper towel 120 is caught by the cutting blade, and the paper towel 120A is not exposed from the slit-shaped paper discharge port 106 during the next forced automatic paper discharge. The paper towel 120 is moved from the lower part of the paper discharge roller 104 to the rear side of the housing in the form of being caught by the paper discharge roller 104, so that the paper is jammed and the paper discharge roller 104 does not move. Furthermore, as shown in FIG. 11, (4) the paper towel 120 is curled by wrapping, especially when it is close to the center, and the paper towel 120 is not discharged from the paper discharge port 106 even if the paper towel 120 is fed out by the paper discharge roller. May enter the lower part of the paper discharge roller. In this case, it is necessary to open the dispenser and manually expose the paper towel 120 from the paper discharge port 106.

<Invention of Claim 7>
The roll paper towel dispenser according to claim 3 or 5, wherein a distance between the protrusion and the nip roller is 0.5 to 1.5 mm.

(Function and effect)
In the present invention, since a shielding plate is provided between the paper discharge roller and the paper discharge port, a paper towel is caught in the paper discharge roller and the paper towel is not moved to the back side, so paper jam is prevented. Further, by preferably detachably attaching the shielding plate, the discharge roller can be easily cleaned and the internal maintenance can be facilitated.
Furthermore, if a cutting blade is provided on the front edge side of the paper discharge port and a projection is provided on the shielding plate that protrudes toward the front edge side of the paper discharge port, the paper towel exposed from the paper discharge port is moved to the front edge side of the paper discharge port. When a person performs a cutting operation, a paper towel hits the front edge of the paper discharge outlet, so that cutting failure is prevented.
In this case, in particular, when the distance between the protrusion and the nip roller is 0.5 to 1.5 mm, the effect of preventing clogging and cutting defects is further enhanced.

  On the other hand, in the automatic paper discharge type roll paper towel dispenser of the present invention, power saving is desired. To achieve the power saving, it is effective to reduce the weight of the driven paper discharge roller. Therefore, as in the invention described in claim 4 of the present invention, when the paper discharge roller has a structure in which a plurality of rolls are arranged at intervals with respect to the rotation shaft, the gap between the rolls is thinned. Thus, weight reduction and power saving can be achieved. In addition, when there is a gap between the rolls in this way, when the cutting failure described in the above background art occurs, paper towels with wrinkles between the rolls enter and the paper jam is promoted. Then, since the shielding plate is positioned between the rolls, such a paper jam does not occur. That is, according to the present invention, power saving and paper jam can be improved at the same time. In addition, the problem of cutting failure can be improved more favorably by providing a protrusion between the rolls.

  On the other hand, in the automatic paper discharge type roll paper towel dispenser, a drive gear may be disposed on the side of the paper discharge roller. In this case, there is a possibility of paper jam in the drive gear portion. By disposing the gear cover, paper jam in the drive gear portion is prevented, and the paper jam prevention effect of the present invention can be effectively obtained.

  According to the present invention described above, paper jams and cutting failures in the automatic paper discharge type roll paper towel dispenser are prevented. Further, power saving can be achieved in the automatic paper discharge type dispenser.

And is installed on the wall surface or the like via the back plate portion 14. The lid 11 includes a front plate portion 16 having a curved surface portion whose upper portion is in series with the top plate portion 12 of the case body 10, and a back side (back plate side) perpendicular to the front plate portion 16. ) And a pair of left and right lid body side plate portions 17, 17 are arranged so as to cover the front side open portion of the case body 10, and constitute the box-shaped housing 1 together with the case body 10. Yes.

  Further, in the illustrated example, the lid body 11 is attached to the case body 10 in a hatched manner via a shaft 10A, and the case body 10 is lowered by pulling the lid body 11 toward the front as shown by a one-dot chain line in FIG. Is opened, the internal mechanisms such as the support 30 and the paper discharge roller 4 inside the housing are exposed, and the roll paper 2 can be replaced. In the illustrated embodiment, when the hatch type is used, the case main body 10 and the lid body 11 are connected via a rotation shaft provided at the lower portion of each side plate portion 15, 17, and a locking protrusion formed on the upper surface of the case main body 10. The front open portion of the case body 10 is closed by the lid 11 by the engagement between the portion 18 and the engagement recess 19 formed on the upper surface of the lid.

  On the other hand, the paper discharge port 6 is provided in a slit shape so as to extend in the width direction of the housing at the lower portion of the housing, and in the illustrated example, in particular, the front side edge of the bottom plate portion 13 of the case body 10 and the lid body 11. A sheet discharge port 6 is formed between the lower end edge of the sheet. The paper discharge port 6 may be formed by providing a bottom plate portion on the bottom plate portion 13 or the lid 11 of the case body 10.

  On the other hand, in the present embodiment, a cutting blade 60 is attached along the front side edge of the paper discharge port 6 in order to easily cut the paper towel 20A exposed from the paper discharge port 6. In the illustrated example, the cutting blade 60 is a saw blade, but is not limited thereto. In addition, this cutter blade can be formed with a metal or a hard plastic resin.

  On the other hand, the support part 30 of the roll part 2 accommodated in the housing 1 can take a known configuration. In the form shown in the figure, it has a pair of arm portions 31, 31 extending from the vicinity of both side plates of the back plate portion 14 toward the front plate side (the front side when the wall surface is mounted), respectively, by a predetermined length. Support bodies 32, 32 are attached to the tips of 31, 31. In addition, not only the example of illustration but the arm parts 31 and 31 may be the aspect extended so that it may protrude in the horizontal direction from the side plate part 15, and are the aspects which hang down from the top-plate part 12. Alternatively, it may stand up from the bottom plate portion 13 toward the top plate portion 12. If the arm parts 31 and 31 place the support part 32 in the predetermined position in the range which does not prevent the effect of this invention, the specific aspect will not be limited.

  In the normal state, the illustrated supports 32 and 32 protrude inward in the horizontal direction at the inside of the housing, and at least one of the supports 32 and 32 is biased to the normal state, As shown by a one-dot chain line A in FIG. 4 with the end portion as an axis, it is configured to jump upward. Then, the distance between the tips 32t and 32t of the pair of support bodies 32 and 32 is set to a distance less than the length (width) of the paper tube of the roll unit 2 in the normal state, and the tips 32t and 32t are jumped upward. In this case, the distance between the tips 32t and 32t of the support is wider than the width of the roll paper 2, and the gap is opened. When the roll paper towel is attached, the roll 32 is inserted between the supports 32 and 32 with the support 32 being flipped up, and then the support is returned to the normal position by urging the support tip 32t, 32t is positioned in the paper tube, and the roll unit 2 is supported by the supports 32 and 32.

  On the other hand, the dispenser X1 of the present embodiment is formed of a non-slip material such as rubber on the outer periphery of a rod-shaped rotating shaft 40 positioned substantially parallel to the axis when the roll unit 2 is attached to the support unit 30. A paper discharge roller 4 having a structure in which a plurality of rolls 41, 41,... Are intermittently arranged, and a nip roller 5 paired therewith are provided in the vicinity of the paper discharge port below (the bottom plate side) of the support 32. The paper towel 20 unwound from the roll portion 2 is sandwiched between the paper discharge roller 4 and the nip roller 5, and the paper towel 20 is discharged from the paper discharge port 6 by the rotation of the paper discharge roller 4. Yes. In the present embodiment, as described above, the paper discharge roller 4 has a structure in which a plurality of rolls 41, 41,... It is intended to reduce power consumption. Further, in the illustrated example, the rolls 41, 41,... Are particularly preferably arranged at intervals so that the central part in the width direction is dense and the side parts are sparse. If it does in this way, when paper towel 20 is pulled by each roller 41, 41 ..., force will be easy to escape to the width direction side, and a wrinkle will not enter easily at the time of feeding. It is possible to increase the contact pressure of the rolls 41, 41 ... to the paper towel by intermittently providing the rolls 41, 41 ... in the width direction, and reliably discharge the paper towel 20A having a predetermined length without causing a slip. Will be able to. The number of rolls 41 is not particularly limited.

  On the other hand, in the present embodiment, the paper discharge roller 4 receives a driving force from a driving source (not shown) via a driving gear 42 provided on one end side (right hand side in the illustrated example) of the rotating shaft 40. Rotated. The driving source is a known motor or the like, and driving and stopping are performed according to a detection signal from the sensor.

  In this embodiment, the paper discharge roller 4 is attached to the case main body 10, and the nip roller 5 is attached to the lid body 11. When the lid body 11 is opened, The nip roller 5 is separated so that the paper towel 20 is released and the maintainability is improved.

  The structure for driving the paper discharge roller 4 is not limited to the configuration via the drive gear 42, and the rotary shaft 41 is rotated by appropriately interposing known mechanisms such as a gear, an endless belt, and a pulley. May be. Further, the rotating shaft 40 may be directly connected to the rotating shaft of the motor coaxially and rotated.

  On the other hand, as a sensor for driving and stopping the driving source, a known sensor that is employed in a dispenser for automatic paper discharge type roll paper towels can be used. For example, an IR sensor that irradiates infrared rays at a predetermined radiation angle and detects that the detected object has entered the detection range that is the irradiation portion can be exemplified.

  In this embodiment, although not shown, such an IR sensor or the like is provided at the lower part of the housing, for example, detects that a detection object such as a user's hand has entered the detection range, and the discharge roller 4 via the control means. By driving the drive source for a predetermined time, the paper towel 20 is exposed from the paper discharge port 6 by the amount of rotation of the paper discharge roller 4 corresponding to the drive time of the drive source.

  On the other hand, in the dispenser X1 of the present invention, a shielding plate 7 is characteristically provided between the paper discharge port 6 and the paper discharge roller 4. In the present embodiment, in particular, the shielding plate 7 is provided so as to stand upward from the rear side edge of the paper discharge port 6, and the rear side edge 61 of the paper discharge port 6 and the standing position of the shielding plate 7 are provided. Are substantially matched with each other, so that smooth guidance of the paper towel 20 to the paper discharge port 6 and the paper towel 20 being caught by the paper discharge roller 4 are effectively prevented. Although the present invention is not limited to this configuration, it is desirable that the shielding plate 7 be provided within about 3 mm in the front-rear direction from the rear side edge 61 of the paper discharge port 6.

  The standing position of the shielding plate 7 is preferably forward (front plate side) from directly below the rotation shaft 40 of the paper discharge roller 4. If the paper towel 20 is positioned in front of the rotary shaft 40 in this way, the paper towel 20 is not easily caught in the paper discharge roller 4 or the roll 40, and the effect of preventing paper jamming is enhanced.

  In the present embodiment, as described above, the paper discharge roller 4 has a structure in which a plurality of rolls 41, 41... Are provided with respect to the rotating shaft 40. The upper edge of the shielding plate 7 is each roll. It is shaped to enter 41A between 41. By adopting such a shape, a part 7A of the shielding plate 7 is also interposed between the rollers 41, 41A 41A, 41..., And the paper towel 20 is prevented from being caught at the position 41A between the rolls. Here, the distance between the shielding plate 7 and the rotary shaft 40 and the roll 41 is preferably 3 mm or less. If it is 3 mm or more, the paper towel 20 may enter between the paper discharge roller 4 (rotating shaft 40, roll 41) and the shielding plate 7.

  The shielding plate 7 is preferably detachable so that it can be removed during maintenance and cleaning of the paper discharge roller 4 and the like. The illustrated shielding plate 7 has locking projections 71 and 71 on both lower ends. The locking holes 72 are formed at appropriate positions in the width direction, and the locking projections 71 and the locking holes 72 are locked to the locking portions 73 formed in the case body 10 so that they can be detachably attached. I am doing so. In addition, in order to make it detachable, not only this structure but an appropriate locking structure etc. can be taken.

  On the other hand, the shielding plate 7 in this embodiment is provided with a protrusion 74 that protrudes toward the front edge of the paper discharge port 6, that is, toward the cutting blade 60. The protrusion 74 projects forward from the rear side edge 61 of the paper discharge port 6, and has the effect of bringing the paper towel 20 </ b> A toward the cutting blade 60 side of the paper discharge port 6. In the illustrated example, the upper portion 74u of the protrusion 74 is cut out so as to slant upward, and the lower end extends downward from the central portion of the shielding plate 7, and the paper towel 20 conveyed from above is removed. The paper discharge port 6 is smoothly guided to the front edge side where the cutting blade 60 is provided. Further, in this embodiment, as described above, the discharge roller 4 has a structure in which a plurality of rolls 41 and 41 are provided with respect to the rotating shaft 40, and a part of the shielding plate 7 is a roll of the rolls 41, 41. The protrusion 74 is preferable because it has a shape that goes in between, and is disposed between the rolls 41 and 41 constituting the paper discharge roller 4 in addition to the side of the paper discharge roller 4. By doing in this way, the paper towel 20 is brought close to the front edge side of the paper discharge outlet 6 provided with the cutting blade 60 in the width direction.

The paper towel 20 </ b> A is easily pulled by the shielding plate 7 toward the front edge side of the paper discharge port 6, so that the paper towel 20 </ b> A is easily pulled in the extending direction of the paper discharge port 6. On the other hand, it becomes easy to hit at a fixed angle, and smooth cutting is performed. Even if a cutting failure occurs unintentionally, even if a part of the cutting edge of the paper towel 20 reaches from the clamping position of the paper discharge roller 4 and the nip roller 5 to the back side, Since the upper portion 74u is slanted, it is guided along this and is smoothly fed toward the paper discharge port 6 without the paper towel being caught in the nip roller 5. It is desirable that the protrusion 74 is disposed near the paper discharge roller. This is because, even when a cutting failure occurs unintentionally, the portion where the paper towel is sandwiched between the paper discharge roller and the pressing roller is less likely to be broken behind the paper discharge roller and the pressing roller.
Here, as shown particularly in FIG. 12, the distance L1 between the protrusion 7 and the nip roller 5 is preferably 0.5 to 1.5 mm. Within this range, the paper is hardly clogged between the protrusion 7 and the pressing roller 5, and a paper towel is likely to hit the cutting blade 60. Therefore, the clogging prevention effect is high, and it is easy to cut. The distance between the protrusion 7 and the nip roller 5 is the distance between the closest parts.

  On the other hand, the dispenser X1 of the present embodiment is provided with a drive gear cover 45 that covers the drive gear 42 provided on the side of the paper discharge roller in order to ensure the effect of preventing the paper jam caused by the shielding plate. As can be understood from FIGS. 5 and 6 in particular, the drive gear cover 45 is slightly wider than the drive gear 42 and is attached so as to cover the front side of the housing of the drive gear 45. Providing the drive gear cover 45 in this manner prevents the paper towel 20 from being caught in the drive gear portion.

  According to the present invention having the above-described configuration, as is understood from a comparison between FIG. 9 showing the conventional dispenser and FIG. 3 showing the dispenser of the present invention, the roll is fed from the roll portion 2 supported by the support portion 30. Even when the paper towel 20 is brought close to the cutting blade 60 on the front edge side of the paper discharge outlet 6 and the user pulls the paper towel 20A at the time of cutting, the paper towel 20A is also used when the pulling toward the front side is weak. It is easy to hit 60, and the cutting failure is effectively prevented, and the presence of the shielding plate 7 prevents the paper towel 20 from being caught in the paper discharge roller 4 and causing a paper jam.

  In the above description, the discharge roller 4 is intermittently provided with a plurality of rolls 41 and 41 with respect to the rotary shaft 40. However, as shown in FIG. 41 may be adopted.

In the present invention described above, problems such as clogging of paper towels due to poor cutting are greatly improved.
(Test example)
In the paper towel dispenser according to the present embodiment, a test was performed on the relationship between the distance between the protruding portion 6 and the nip roller 7 and “the degree of clogging” and “the contact with the cutting blade”.
The results are as shown in Table 1 below. Good results were obtained particularly when there was an interval of 0.5 to 1.5 mm.
The test is the result of 50 cutting tests, and the evaluation of “degree of clogging” in the table is as follows: ○: No clogging (0 clogging), Δ: Almost clogging (clogging 5 Less than the number of times), x: Clogged (clogged 5 times or more).
In addition, the evaluation of “scoring to the cutting blade” is as follows: ○: The paper towel surely hits the cutting blade, △: The paper towel almost hits the cutting blade, ×: The paper towel may not hit the cutting blade, Means.
