Description

  The present invention relates to a dispenser for roll paper in which sanitary thin paper is wound into a roll.

Roll paper obtained by winding a strip of sanitary thin paper into a roll is well known as a toilet roll, kitchen roll, roll paper towel, and the like.
This roll paper (hereinafter also simply referred to as “roll”) may be used by using a dispenser that supports the inside so as to be freely rotatable and can be appropriately drawn out from a takeout port.
Most of the dispensers of this type hold one roll as shown in Patent Document 4 below, use up one of them, and then replenish the next one for use.
In this conventional dispenser, after all of the roll paper has been used up, it is necessary to bring in new roll paper from the storage location and replenish it. There is a period during which it cannot be used.
In order to shorten this period, some conventional dispensers have a spare roll storage part in the dispenser, but there is no substitute that it cannot be used for a certain period of time before setting a new roll paper. Only the stock location is provided, and only one of the above items is accommodated. Also, with such a dispenser, there are many cases where it is not noticed that the roll that can be pulled out has been used up.
In view of these problems, for example, as disclosed in Patent Documents 1 to 3 below, a cassette type paper is automatically discharged from a spare roll.
However, this dispenser has a complicated mechanism and has the trouble of setting a roll in a cassette, which is disadvantageous in terms of cost and operation.

The roll paper dispenser X1 of the present invention is, for example, a sanitary thin paper roll dispenser used for wiping skin such as kitchen paper, towel paper, and the like, and for wiping food drip and moisture.

  The dispenser X1 of the present invention is made of a synthetic resin such as ABS resin, for example, and includes a case body 1, a roll paper support / discharge mechanism provided as appropriate inside the case body, and a lid 2.

  The case body 1 includes a top plate portion 10, a bottom plate portion 11, a back plate portion 12, and left and right side edges extending at a right angle to the back plate portion 12 at both side edges or both side edges of the back plate portion 12. It has a pair of main body side plate parts 13 and 13. In the illustrated form, as understood from the side view of FIG. 2, the front side of the main body side plate portions 13, 13 is missing, but the present invention is not necessarily limited to this form.

  Further, in the case main body 1 of the present invention, the front side of the bottom plate portion 11 is inclined toward the top plate portion 10 side, and an elongated lower outlet 14 is formed in the inclined portion. As the bottom plate portion 11 is inclined in this manner, the paper sheet can be taken out more easily.

  On the other hand, the lid body 2 of the present invention has a front plate portion 20 having a curved surface portion such that the upper portion thereof is in series with the top plate portion 10 of the case body 1 and extends to the front at a right angle to the front plate portion 20. It has a pair of left and right lid body side plates 21, 21, and is arranged so as to cover the front side open part of the case body 1, and constitutes a box-shaped dispenser outline together with the case body 1.

  The lid 2 is attached to the case main body 1 in a hatched manner, and the front side of the case main body can be in an open exposed state by a flip-up type or a pull-down type. In the hatch type, a hinge mechanism 23 is provided on the front side edge of the top plate portion 10 of the case body 1 and the upper rear edge of the front plate portion 20 of the lid 2 as shown in the example of the drawing. Good. As another example, the hinge mechanism may be provided on the front side edge of the bottom plate portion 11 of the case body 1 and the lower edge of the front plate portion 20 of the lid 2. Furthermore, although not shown, a pair of convex portions are provided on the upper or lower portion of each main body side plate portion, and a pair of fitting holes corresponding to the convex portions are provided on the upper or lower portion of each lid side plate portion, and these are fitted. This can be achieved by connecting the case main body and the lid. Of course, the convex portion and the fitting hole may be paired, and it does not matter which is the case main body side.

On the other hand, the dispenser X1 of the present invention adopts the following characteristic roll paper support / discharge mechanism / structure in the interior.
First, the dispenser X1 of the present invention has a pair of left and right upper support means 30 and 30 that rotatably support the roll paper 5 on the top plate portion 11 side (upper side) in the case body 1. In the illustrated example, the upper support means 30, 30 has a pair of support pieces 31, 31 that protrude from the main body side plate portions 13, 13 toward the width direction of the case main body 1 at the upper portion inside the case main body 1. The tip portions of the support pieces 31 are arranged so as to freely enter the tube core 51 of the roll paper 5, and the roll paper 5 is rotatably supported at the upper position in the case body 1.

  Further, the upper support means 30, 30 is a telescopic mechanism in which the normal state is extended by positioning the biasing means on the base end side such as a rubber spring or a coil spring on the base end side of the support pieces 31, 31. A telescopic structure can be illustrated, and in this way, the roll paper 5 can be easily inserted between the support pieces from the front side when the support pieces 31 are pushed into the side plate.

  In addition, the support means may be configured to provide a rotatable rotation shaft that protrudes toward the inner surface in the width direction at the front ends of a pair of support members that protrude from the upper portion of the back plate portion toward the front plate portion. . If this rotating shaft enters into the axis of the roll paper, the roll paper can be rotatably supported on the upper part of the dispenser.

  On the other hand, the dispenser X1 of the present invention includes a sensor (not shown) that is supported by the upper support means 30 and 30 and monitors the roll diameter of the roll 5. The installation position of the sensor in the case main body 1 can be set to an appropriate position as long as the roll paper does not interfere with the rotation of the roll paper and the movement of the roll paper described below. The sensor may be a non-contact type sensor typified by an optical sensor. For example, when the roll diameter decreases to a predetermined diameter, the sensor terminal becomes non-contact and senses the increase or decrease of the roll diameter. Such a contact type sensor may be used. For this type of sensor, known sensor technology can be employed.

  On the other hand, the dispenser X1 of the present invention is provided with an opening means for releasing the roll support of the upper support means in response to a decrease in the roll diameter of the roll 5 detected by the sensor. Examples of the opening means include a mechanism for expanding and contracting the support pieces 31 and 31 and a mechanism for allowing the support pieces 31 and 31 to be tilted by being positioned on the base end side of the support pieces 31 and 31. In the illustrated embodiment, a mechanism is employed in which the support pieces 31, 31 are tilted downward with the support piece rotating shafts 32, 32 as axes. The control mechanism for tilting the support pieces 31, 31 downward in accordance with the sensing signal from the sensor is a known control mechanism. Further, it is desirable that the dispenser X1 is configured to automatically return to the pre-opening state after being opened once. Of course, it may be configured to return manually. This may be according to the known control technique described above.

  Furthermore, the dispenser X1 of the present invention includes lower support means 40 that is positioned below the upper support means 30 and 30 and receives and supports the roll paper 5 in a rotatable state. Examples of the lower support means 40 include a semi-cylindrical shape having an open upper portion or a receiving plate-like shape having a curved plate having a lower concave shape. If such a lower support means 40 is used, the surface thereof should be a smooth surface so as not to hinder the rotation of the roll.

  On the other hand, the dispenser X1 of the present invention also includes a sensor (not shown) that is supported by the lower support means 40 and monitors the remaining roll. What is necessary is just to install the installation position of a sensor suitably in the inside and outside of a dispenser in the range which does not prevent the effect | action of this invention. This sensor may be a non-contact type sensor represented by an optical sensor as well as a sensor for monitoring the diameter of the roll 5 supported by the upper support means 30. For example, the roll diameter may be a predetermined diameter. It may be a contact type sensor that senses the presence or absence of a roll diameter or a paper sheet that is fed out from the sensor terminal when the sensor terminal decreases. For this type of sensor, known sensor technology can be employed.

  On the other hand, the dispenser X1 of the present invention is arranged so as to be parallel to the axis of the roll supported by the respective support means 30, 40, while maintaining the parallel of the axis, A movable roll 50 is provided that is movable between the (back plate portion side) and the front side (front plate side).

  Further, the dispenser X1 of the present invention is a paper sheet 5A fed out from the roll paper 5 supported by the upper support means 30 and 30 in a state where the movable roll 50 is located on the front side (lid side). On the other hand, there is provided a holding roll 60 that comes into contact with the movable roll 50 by contacting from the front side (front plate side). What is necessary is just to arrange | position this control roll 60 etc., for example so that it may bridge | crosslink between a main body side board part or a cover body side board part.

  Here, when the movable roll 50 is located on the back side (back plate side), the separation distance from the holding roll 60 senses at least the roll diameter of the roll supported by the upper support means 30 described above. The sensor is configured to be wider than the predetermined diameter or less detected by the sensor. Thereby, when the upper support means is opened, the roll can pass between the movable roll 50 and the restraining roll 60.

  On the other hand, in a normal state, the movable roll 50 is positioned on the back side (back plate side), and a sensor for detecting the paper remaining of the roll supported by the lower support means 40 is supported by the lower support means 40. When it senses that the paper roll is gone, it automatically moves temporarily from the back side (back plate side) to the front side (front plate side).

  In the illustrated example, the movable roll 50 has both end shafts connected to a distal end portion of a swing guide 51 connected to a rotating shaft 52 whose base end is rotatable at the lower portion of the case body 1. When the tip of the swing guide 51 with the rotating shaft as the shaft swings to the front side (front plate side) and back side (back plate side), it moves in a state parallel to the roll shaft. It is configured to The moving mechanism of the movable roll 50 may be configured such that rails extending on the front side and the rear side with respect to the main body side plate portion are provided so that both end shafts of the movable roll move on the rail. It can be illustrated.

  In addition, the movement of the movable roll 50 can be configured such that, for example, the swing guide 51 is swung in an appropriate direction according to the sensor and according to the detection signal. The swing guide 51 can be moved by a known servo mechanism, driving means such as a motor (not shown). Further, if the moving mechanism of the movable roll is a rail, the movable roll 50 can be configured to move on the rail disposed on the side plate portion by the servo mechanism in accordance with the detection signal of the sensor. .

  On the other hand, although not shown, the movable roll is provided with a temporary fixing means for temporarily fixing a paper end portion of unused roll paper supported by the upper support means. The temporary fixing means can be exemplified by small protruding pieces arranged at both ends of the movable roll inward in the width direction and slightly spaced from the roll peripheral surface of the movable roll. The paper end is temporarily fixed to the movable roll by positioning the paper end between the small protruding piece and the roll peripheral surface and loosely holding it.

  Further, in the dispenser X1 of the present invention, the dispenser X1 is unrolled from the roll paper 5 that is positioned below the movable roll 50 and the holding roll 60 and in the vicinity of the takeout port 14 and supported by the upper support means 30 or the lower support means 40. A pair of feed rolls 70 and 70 for guiding the end portion of the paper sheet to the takeout port 14 are provided. The pair of feed rolls 70 and 70 are a pair of rotatable rolls arranged so as to be parallel to the supported roll axis, as shown in the illustrated example. It is supported on the side plate part of the main body.

  Further, the pair of feed rolls 70 and 70 are configured to rotate in conjunction with the rotation of the movable roll 50 when the movable roll 50 is located on the front side. Preferably, this interlocking is performed according to the remaining paper of the roll paper supported by the lower support means 30. That is, the paper sheet fed from the paper roll supported by the lower support means 40 is sensed by the sensor, and interlocking or non-interlocking is selected according to the sensing signal. This sensor can be shared with a sensor for detecting the remaining amount of the lower support means and moving the movable roll 50. A separate sensor may be provided. As the sensor of the upper support means, a known non-contact and contact sensor can be used as the sensor, and the installation position thereof can also be an appropriate place.

  Furthermore, the dispenser X1 of the present invention is preferably configured such that the feed rolls 70 and 70 can be driven by a drive source (not shown). Examples of the driving source include a power supply by an AC adapter and a motor mechanism that operates by receiving power from a battery such as a dry battery. The motor mechanism or the like, for example, automatically detects the paper sheet of an appropriate length that has been sensed when the hand is held under the take-out port by a sensor function so that the paper sheet is exposed from the take-out port. A switch that enables operation of the drive source may be arranged outside the dispenser X1, which is preferably configured to feed, and may be operated by this.

Characteristically, the dispenser X1 of the present invention having the above-described mechanism and configuration is operated and used as follows and exhibits its operational effects. This will be described in detail with particular reference to FIGS.
First, as shown in FIG. 5 in particular, the paper sheet 5a fed from the roll paper 5A supported by the upper support means 30 and 30 is sandwiched between the feed rolls 70 and 70, and the leading end of the paper sheet 5a is taken out. To the outside of the dispenser X1.
By attaching the roll paper 5A, the sheets 5a drawn out from the roll paper 5A supported by the upper support means 30 and 30 from the outside of the dispenser can be sequentially pulled out and used.

  Then, when the sensor senses that the roll diameter of the roll paper 5A has decreased due to use, the upper support means 30 and 30 are opened and the roll paper 5A has a predetermined diameter as shown in FIGS. Is moved by a free fall to the lower part inside the dispenser so as to pass through between the movable roll 50 and the holding roll 60. This movement may not be due to complete free fall. Guide means for appropriate lowering can be provided.

  Note that it is desirable that the sensor senses when the roll diameter becomes about 1/5 of the start of use. For example, in the case of 250 m roll paper for business use and home use, the diameter is about 175 mm, so that when this roll paper is reduced to about 35 mm, this is detected. When this level is reached, there is a remaining of about 50 m, and a sufficient amount of the roll paper remains until the next roll paper described later is set, and the period during which the roll paper cannot be used can be minimized. Also, with regard to the weight and fall of the roll paper of this level, since it is around 370 g, the weight burden on the dispenser or mechanism can be reduced.

  At this time, as shown in FIG. 7, the end portion of the paper sheet 5 a fed out from the roll 5 </ b> A supported by the upper support means 30, 30 is sandwiched between the feed rolls 70, 70, and further The tip is exposed to the outside of the dispenser through the take-out port 14. Therefore, even if the roll portion moves from the upper support means 30, 30 between the movable roll 50 and the restraining roll 60 and moves to the lower support means 40, the end of the paper sheet 5a of the roll paper 5A remains at the outlet. The state exposed from 14 is maintained, and there is no problem in pulling out and using the paper sheet 5a from the outside of the dispenser X1. As described above, it is desirable to set the roll diameter sensed by the sensor to a certain extent so that the paper sheet can be fed out from the roll paper 5A supported by the lower support means 40. .

  When the roll paper 5A supported by the upper support means 30 and 30 is moved to the lower support means 40 in this way, a new roll paper can be supported by the upper support means.

  And as FIG. 8 shows, while the upper support means is not supported in this way, a new roll paper is supported by the upper support means. At this time, the paper end portion of the roll paper newly supported by the upper support means is temporarily fixed to the temporary fixing means of the movable roll located on the back plate side. Thus, the roll paper 5B newly supported by the upper support means 30 and 30 is ready for use.

  Then, as shown in FIG. 9, when the sensor senses that the remaining amount of the paper sheet 5a from the roll paper 5A supported by the lower support means 40 has run out or has become extremely small, The roll 50 moves to the front plate side. At this time, since the movable roll and the feed roll 70 are interlocked with each other, the feed rolls 70, 70 are driven by a switch that can be operated from the outside of the dispenser or automatically. In conjunction with each other, the paper sheet 5b fed from the new roll paper 5B supported by the upper support means 30 and 30 is guided to the take-out port 14 through the pair of feed rolls 70 and 70.

And if the paper end part of a new roll paper is clamped between the feed rolls 70 and 70 in this way, the said movable roll 50 will move to the back side again. At this time, the temporary fixing means of the movable roll comes off.
Thus, the paper sheet 5b from the roll paper 5B newly supported by the upper support means 30, 30 can be used.

  In the dispenser X1, the movement control of the movable roll and the support release control of the upper support means 30 according to the sensing signals from the sensors are not particularly limited, and may be performed by each conventionally known drive control technique. Further, the upper opening means, the movable roll, and the feed roll may be linked control or non-linked control.

  As described above, according to the roll paper dispenser of the present invention, it is a relatively simple mechanism, and after the roll paper is used up, there is no complicated operation, and there is almost no period of paper breakage. Can be used.
