  Hereinafter, the present invention will be specifically described based on preferred embodiments.

  1 and 2 show a paper holder device 1 according to an embodiment of the present invention. This paper holder device 1 is attached to a wall surface of a toilet, holds a paper roll P formed by winding toilet paper therein, and removes a paper Pa from the paper roll P by a predetermined length as required by the user. The paper is folded in a zigzag manner to make a folded paper Pc, and the folded paper Pc is cut off at a position near the paper roll P for use, from the feeding of the paper Pa to the cutting and cutting. A series of operations are automatically performed. Such automatic operation saves the user the trouble of pulling out the paper Pa by hand, folding it and cutting it out, and is particularly suitable for the elderly.

  The paper holder device 1 includes a holder main body 2 and an attachment portion 3 connected and fixed to the lower surface side of the holder main body 2 via a fixed bracket 29.

A: Configuration of holder main body 2 A-1: Holder main body 2
As shown in FIGS. 1 to 6, the holder main body 2 includes a case body 4 including a pair of left and right side wall parts 5 and 6 and a back wall part 7. The paper roll support unit 15, the paper delivery unit 20, the paper folding holding unit 30, and the paper cutting unit 40 are accommodated and disposed.

  One end of a curved plate-shaped opening / closing cover 10 composed of a front surface portion 10 a and an upper surface portion 10 b is pivotally supported by a fulcrum shaft 11 at the upper end of the back wall portion 7 of the case body 4. The internal space S of the case body 4 is configured to be opened and closed. The paper roll P is attached to and detached from the internal space S by opening the opening / closing cover 10 (see FIG. 2).

  Further, side covers 8 and 9 are respectively mounted on the outer sides of the left and right side wall portions 5 and 6 of the case body 4, and in particular, a space surrounded by the side wall portion 6 and the side cover 9 is a drive unit described later. It is used as 60 arrangement spaces (see FIG. 3).

A-2: Paper roll support 15
As shown in FIGS. 4 to 6, the paper roll support portion 15 includes a pair of front and rear support rollers 16 disposed in parallel across the pair of left and right side wall portions 5 and 6 at the lower end portion of the internal space S. 16 and a curved plate-shaped guide plate 17 disposed between the intermediate portion in the height direction of the back wall portion 7 and the vicinity of the support roller 16 on the back side, and the support roller 16 on the near side. It is constituted by a curved plate-like guide plate 44 provided in a rotary blade unit 41 described later.

  As shown in FIG. 6, the paper roll P can be rotated (that is, paper Pa can be fed out) by being placed on the upper surface side so as to straddle the pair of support rollers 16 and 16. At the same time, displacement in the front-rear direction is restricted by the guide plate 17 positioned on the back side of the support rollers 16 and the guide plate 44 positioned on the near side.

  That is, the paper roll support portion 15 is held in a free state without passing the core rod through the paper roll P, and the positional deviation is performed by the guide plates 17 and 44. The attaching / detaching operation of the core rod is not required for attaching / detaching, and the operation can be easily and quickly performed.

  Note that the radial displacement of the paper roll P by the guide plate 17 and the guide plate 44 is restricted when the diameter of the paper roll P is large, that is, the support rollers 16 of the paper roll P, This is effective when the amount of depression into the gap between the sixteen is small and the positional displacement regulating action by the support rollers 16 and 16 itself is small. When the diameter of the paper roll P is reduced, the amount of the paper roll P that falls into the gap between the support rollers 16 and 16 increases, so that the positional deviation of the paper roll P is restricted only by the support rollers. 16 and 16 itself.

A-3: Paper sending unit 20
As shown in FIG. 5, the paper feed unit 20 is for pulling out paper Pa from the paper roll P supported by the paper roll support unit 15 and sending it out to the front side of the internal space S. The feed roller 21 and the presser roller 22 are provided.

  The delivery roller 21 is a roller having a surface with a high coefficient of friction made of rubber or the like, and is attached to the upper portion of the front end of the case body 4 so as to rotate between the pair of left and right side wall portions 5 and 6. ing. A roller rotation shaft 23 provided at one end of the feed roller 21 extends through the side wall 6 to the outer surface side of the side wall 6, and a feed drive gear 55 is attached to the extended end. (See FIG. 3). The delivery roller 21 is rotated in the direction of arrow a (see FIG. 5) by the delivery drive gear 55 being driven by a drive gear 65 of a drive unit 60 (described later) meshing with the delivery drive gear 55.

  The pressing roller 22 presses the paper Pa wound around the feeding roller 21 toward the feeding roller 21 from above, and feeds the paper Pa in cooperation with the feeding roller 21. The opening / closing cover 10 is located inside the corner portion of the front surface portion 10a and the upper surface portion 10b of the opening / closing cover 10 and parallel to the sending roller 21 at a portion corresponding to the sending roller 21 in the closed state of the opening / closing cover 10. It is attached so that it can rotate over the side ribs 12 and 12 located on both sides in the width direction. The presser roller 22 is urged by a spring (not shown) in a direction away from the inner surface of the opening / closing cover 10 (in other words, in a direction approaching the delivery roller 21), and between the feed roller 21 and the appropriate pressure roller 22. It is designed to generate a pressing force.

  Therefore, with the opening / closing cover 10 opened, the paper Pa is pulled out from the paper roll P held by the paper roll support 15 and extended downward through the upper side of the feed roller 21. When the opening / closing cover 10 is closed, the paper Pa is automatically nipped and gripped between the feed roller 21 and the presser roller 22. When the delivery roller 21 is rotated in this state, the paper Pa is sequentially delivered downward from the delivery roller 21 by the rotation of the delivery roller 21.

In this case, the feed roller 21 and the presser roller 22 do not have to be formed in a straight bar shape having a flat outer peripheral surface, and in short, the paper Pa may be sent out by a frictional force. For example, the feed roller 21 Alternatively, a rubber O-ring may be attached to the presser roller 22 so that a frictional force is applied locally to the paper Pa.
A-4: Paper cutting part 40
As shown in FIGS. 4 to 6, the paper cutting unit 40 is disposed below the rotary roller unit 41 disposed below the feed roller 21 and the presser roller 22 of the opening / closing cover 10. These fixed positions are relatively set so that the rotary blade unit 41 and the fixed blade unit 42 are in contact with each other in a state where the fixed blade unit 42 is configured and the open / close cover 10 is closed. .

  As shown in FIG. 7, the rotary blade unit 41 includes a blade holder 43, a rotary shaft 47, and a rotary blade 48.

  The blade holding part 43 is a horizontally long box-like body that is arranged and fixed between the side wall parts 5 and 6 of the case body 4, and forms a part of the paper roll support part 15. A plate-shaped guide plate 44, a pair of upper and lower flange plates 45, 45 protruding from the back side of the guide plate 44 and extending in the longitudinal direction of the guide plate 44, and both ends of the flange plates 45, 45 Side plates 46, 46 provided are provided.

  A rotary shaft 47 is attached to the inside of the blade holder 43 with its shaft end 47 a extending outward from the side plate 46, and on the outer peripheral surface of the rotary shaft 47, The rotary blade 48 having the shape is attached in an inclined manner so as to gradually displace from the one end side of the rotary shaft 47 toward the other end side in the rotational direction of the rotary shaft 47. In the state where the blade holder 43 is assembled on the case body 4 side, as shown in FIG. 3, the shaft end 47a of the rotary shaft 47 extends through the side wall 6 to the outer surface side. A cutting drive gear 56 is attached to the extended end.

  The rotary shaft 47 is rotated in the direction of the arrow b (see FIG. 7) by being driven by a drive gear 65 of a drive unit 60 (described later) with which the cutting drive gear 56 meshes.

  The rotary shaft 47 is configured such that the rotary blade 48 faces the back side of the blade holder 43 when the rotation is stopped, and the rotary blade 48 is exposed to the front side of the blade holder 43 only during rotation. The rotation stop position is set. The purpose of this is to prevent the human hand from touching the rotary blade 48 when pulling the paper Pa downward through the front side of the rotary blade unit 41 in preparation work when using the paper holder device 1. is there.

  As shown in FIG. 8, the fixed blade unit 42 is configured by attaching a band-plate-shaped fixed blade 52 to a horizontally long box-shaped blade holding portion 49, and the fixing portion 50 provided on the blade holding portion 49 is connected to the fixed blade unit 42. The opening / closing cover 10 is attached to the opening / closing cover 10 by being fastened and fixed to the inner surface side of the front surface portion 10a. In this case, the fixed blade 52 is not fixed to the blade holder 49, but in the thickness direction (arrow ef direction) around the support shafts 53 provided at both ends of the fixed blade 52. And is urged by a spring (not shown) in a direction away from the fixed portion 50 (arrow direction e).

  As shown in FIGS. 4 and 6, the rotary blade unit 41 and the fixed blade unit 42 face each other in the front-rear direction when the open / close cover 10 is closed, and the rotary blade unit 41 rotates. The blade 48 and the fixed blade 52 of the fixed blade unit 42 come into contact with the rotation of the rotary shaft 47, and act so as to cut the paper Pa between them.

  In this case, the rotary blade 48 is attached to the rotary shaft 47 so as to be gradually displaced from the one end side of the rotary shaft 47 toward the other end side in the rotational direction. The rotary blade 48 and the fixed blade 52 are not in contact with each other at the same time, but are in contact with each other in such a manner that the contact point sequentially moves from one end side to the other end side of the fixed blade 52. As a result, the shear angle of the rotary blade 48 and the upper fixed blade 52 with respect to the paper Pa becomes small, and the paper Pa is cut smoothly and accurately.

Further, the fixed blade 52 is elastically biased in the direction of the arrow e in FIG. 8 (that is, the direction approaching the paper Pa inserted between the rotary blade 48 and the fixed blade 52 (see FIG. 6)). Therefore, for example, even when the interval between the rotary blade 48 and the fixed blade 52 or the mutual contact pressure thereof deviates from the design value due to an assembly error between them or wear of the blade edge, etc., When the fixed blade 52 is elastically displaced, the deviation is absorbed and relaxed, and is always maintained at an appropriate interval or an appropriate contact pressure.
A-5: Drive unit 60
The drive unit 60 selectively drives the paper feeding section 20 and the paper cutting section 40, and is disposed on the outer surface side of one side wall section 6 of the case body 4 as shown in FIG. Is done.

A wheel 64 is attached, a swing arm 66 is pivotally supported on a support shaft 68 of the worm wheel 64, and a drive gear 65 is attached to the front end side of the swing arm 66 via a support shaft 69. The drive gear 65 and the worm wheel 64 are interlockedly connected by an O-ring 67. Further, the end portion of the support shaft 69 is engaged with a guide hole 73 provided in the fixed bracket 61, and the swing arm 66 is engaged by engagement between the support shaft 69 and the end portion of the guide hole 73. The rocking range is regulated.

  In the drive unit 60, when the motor 62 rotates forward, the rotational force is transmitted from the worm gear 63 to the worm wheel 64, and the rotation of the worm wheel 64 is further transmitted through the O-ring 67. This is transmitted to the drive gear 65, whereby the drive gear 65 is rotationally driven in the direction of arrow n. At this time, the driving gear 65 is subjected to a rotational force around the support shaft 68 via the O-ring 67, so that the driving gear 65 is integrated with the swing arm 66 in the direction of arrow h. It will turn to. The position of the driving gear 65 at this time is referred to as a “first position”.

  Conversely, when the motor 62 rotates in the reverse direction, the rotational force is transmitted from the worm gear 63 to the worm wheel 64, and the rotation of the worm wheel 64 is transmitted to the drive gear 65 via the O-ring 67, As a result, the drive gear 65 is rotationally driven in the direction of the arrow m. At this time, the driving gear 65 is subjected to a rotational force about the support shaft 68 via the O-ring 67, so that the driving gear 65 is integrated with the swing arm 66 in the direction indicated by the arrow g. It will turn to. The position of the drive gear 65 at this time is referred to as a “second position”.

  By utilizing such drive characteristics of the drive unit 60, the paper feed unit 20 and the paper cutting unit 40 are alternatively driven by a single motor 62. That is, in this embodiment, as shown in FIGS. 3, 11, and 12, the feeding drive gear 55 on the paper feeding unit 20 disposed on the side wall 6 of the case body 4, and the paper cutting In addition to the cutting drive gear 56 on the part 40 side, an intermediate gear 57 having a large diameter gear 57 a and a small diameter gear 57 b that meshes with the cutting drive gear 56 is provided.

In the state where the drive gear 65 is set to the first position, as shown in FIG. 11, the drive gear 65 meshes with the delivery drive gear 55, and the delivery drive gear 55 is moved in the direction of the arrow p. Rotate. On the other hand, in the state where the drive gear 65 is set at the second position, as shown in FIG. 12, the drive gear 65 meshes with the delivery drive gear 55 via the intermediate gear 57, and the delivery drive. The gear 55 is rotated in the arrow q direction.
B: Configuration of the attachment portion 3 The attachment portion 3 is attached to the lower surface side of the holder main body portion 2 and constitutes the paper folding holding portion 30. As shown in FIGS. A pair of left and right side walls 31, 31, a bottom wall 32 straddling each other, and a front regulating wall 34 rising on the front end side of the bottom wall 32 are integrally formed, and a plate-like shape is formed on the back side of the bottom wall 32. The rear regulating wall 35 made of a body is arranged in an inclined state with its upper end inclined backward.

  The front restricting wall 34 and the rear restricting wall 35 are in contact with the paper Pa that sequentially descends from the paper delivery unit 20 side to the bottom wall 32 side, thereby restricting the swing width of the paper Pa. The folding paper Pc is folded in a zigzag shape so as to form a folding paper Pc (see FIGS. 2 and 3), and the folding paper Pc is folded depending on the facing distance between the front regulating wall 34 and the rear regulating wall 35. A width is defined. For this reason, in this embodiment, as shown in FIG. 5, the arrangement position of the rear regulating wall 35 in the depth direction of the bottom wall 32 can be adjusted in multiple stages, thereby reducing the folding width of the folding paper Pc. It can be changed. Specifically, a pair of protrusions 74 and 75 arranged vertically in a rearward tilted state are provided on the inner surface side of the pair of left and right side walls 31 and 31 in multiple stages at predetermined intervals in the depth direction of the bottom wall 32.

A series of operations from the formation to the cutting of the paper Pa by the paper cutting unit 40 is automatically performed. This will be specifically described below.

  As shown in FIG. 13, the detection signals of the sensors 71 and 72 are respectively input to the controller 70. In this controller 70, based on the detection signals of the sensors 71 and 72, a control signal is sent to the motor 62 so as to execute “paper feeding operation” and “paper cutting operation” under a preset control mode. Is output to control its operation.

Here, the basic idea about the control mode will be described.
(A) The operation of the paper holder device 1 (that is, the paper Pa feeding operation by the forward rotation of the motor 62) is started by detecting the approach of a human hand in the first sensor 71. This is for eliminating the direct switch operation by a person and ensuring convenience and ease of use.

However, the condition is that the second sensor 72 detects that the folded paper Pc is not present in the folded paper holder 30. This is for avoiding the start of the operation of the paper holder device 1 based on an unnecessary movement of a person.
(B) After receiving the detection signals of the first sensor 71 and the second sensor 72 and starting the paper Pa feeding operation by the forward rotation of the motor 62, until the operation of (e) below is completed. Even if a detection signal is output from the first sensor 71, this control signal is ignored for control purposes. This is to prevent the operation of the paper holder device 1 from being confused by the human operation after the operation of the paper holder device 1 and to smoothly perform a series of operations of the paper holder device 1.
(C) The feeding length of the paper Pa (that is, the length of the folded paper Pc) is adjusted by setting the driving time of the paper feeding unit 20 by the motor 62. In this embodiment, the drive time is set by software in the controller 70, but in other embodiments, it is also possible to set the timer by manual operation.
(D) The cutting operation of the paper Pa after the completion of the feeding of the paper Pa is performed by the reverse rotation activation of the motor 62. This is because the “feeding” and “cutting” of the paper Pa are not performed at the same time, but are always performed alternatively. Therefore, both the “feeding driving” and the “cutting driving” of the motor 62 are performed. It is used for.
(E) After cutting the paper Pa in the paper cutting unit 40, the motor 62 is driven to rotate forward to feed the paper Pa by a predetermined amount. This is because if the cutting edge Pb (see FIG. 2) of the paper Pa is stopped at the paper cutting portion 40, the cutting edge Pb is caught by the paper cutting portion 40 at the next feeding and the proper feeding is inhibited. Since there is a fear, the purpose is to send the cutting edge Pb ahead of the paper cutting portion 40. This feed amount (that is, the pre-feed amount) is adjusted by setting the driving time of the paper feed unit 20 by the motor 62. In this embodiment, the drive time is set by software in the controller 70, but in other embodiments, it is also possible to set the timer by manual operation.
D: Description of Operation of Paper Holder Device 1 The actual operation of the paper holder device 1 based on the above “basic idea” will be described with reference to the flowchart shown in FIG.

  Prior to use of the paper holder device 1, the opening / closing cover 10 is opened to set the paper roll P on the paper roll support portion 15, and the paper Pa is pulled out from the paper roll P, and this is sent to the feeding roller 21. Is further pulled down to the lower side through the front of the rotary blade unit 41. Thereafter, the opening / closing cover 10 is closed. With the lid of the opening / closing cover 10, the presser roller 22 comes into contact with the feed roller 21 with the paper Pa interposed therebetween. Further, the fixed blade 52 of the fixed blade unit 42 is in close proximity to the rotating shaft 47 of the rotary blade unit 41 with the paper Pa interposed therebetween. At this time, the rotary blade 48 of the rotary blade unit 41 faces the back side of the rotary blade unit 41 and is not exposed on the front side.

  The paper holder device 1 is now ready for use.

  The control of the motor 62 that accompanies the use of the paper holder device 1 is based on the condition that the first sensor 71 outputs the first detection signal in step S1 and that the detection signal is not output from the second sensor 72 in step S2. To be started.

  When the above conditions are satisfied, the motor 62 is started in the normal direction in response to this. When the motor 62 starts to rotate forward, the drive gear 65 of the drive unit 60 swings in the direction of arrow h in FIG. 9 and is set to the “first position”. Engage with the gear 55. Accordingly, the feed roller 21 is rotated with the rotation of the feed drive gear 55, and the paper Pa is fed from the paper roll P by the cooperation of the feed roller 21 and the presser roller 22 corresponding thereto.

  This paper Pa delivery is continued for a preset time “Ta” corresponding to the required delivery amount (step S4). As the set time “Ta” elapses, the rotation of the motor 62 is stopped (step S5), but this stopped state is continued for a preset set time “Tb”. This is for ensuring the proper start of the reverse rotation drive of the motor 62 to be performed next in consideration of the inertia rotation of the motor 62 or the delivery roller 21.

  In addition, while the paper feeding unit 20 performs the paper Pa feeding operation, the paper folding holding unit 30 sequentially folds the paper Pa fed in a hanging state from the upper side in a zigzag manner. Paper Pc is formed.

  As the predetermined time “Tb” elapses, the motor 62 is driven in reverse (step S7), and the drive gear 65 of the drive unit 60 swings in the direction of the arrow g in FIG. And is engaged with the intermediate gear 57. Accordingly, the cutting drive gear 56 on the side of the paper cutting unit 40 meshing with the intermediate gear 57 is rotationally driven.

  As the cutting drive gear 56 rotates, the rotary shaft 47 of the rotary blade unit 41 rotates, and the rotary blade 48 attached to the rotary shaft 48 has one end in the blade width direction with respect to the fixed blade 52 of the fixed blade unit 42. By sequentially contacting from the side toward the other end, the paper Pa sandwiched between the rotary blade 48 and the fixed blade 52 is cut, and the folded paper Pc on the paper folding holding unit 30 side is cut. Separated from the paper Pa.

  The cutting operation of the paper cutting unit 40 is continued for the set time “Tc” (step S8), and is terminated when the rotation of the motor 62 stops (step S9) as the set time “Tc” elapses.

  The stop state of the motor 62 is continued for a preset time “Td” (step S10), which is performed next in consideration of the inertia rotation of the motor 62 or the delivery roller 21. This is to ensure proper start of forward rotation of the motor 62.

  With the elapse of the set time “Td”, the forward rotation driving of the motor 62 is started (step S11), and the feeding roller 21 on the paper feeding unit 20 side is rotated again to “pre-feed” the paper Pa. Is executed only for a set time “Te”, and the cutting edge Pb of the paper Pa cut by the paper cutting unit 40 is fed downward from the paper cutting unit 40 by a predetermined length.

  As the set time “Te” elapses, the rotation of the motor 62 is stopped (step S13), thereby completing a series of operations of the paper holder device 1, and the paper holder device 1 is ready for the next use. It will be in a standby state.

  As described above, the paper holder device 1 starts operating when a person desires to use the folded paper Pc and places his hand in the vicinity of the paper folding holding unit 30 and automatically after a predetermined time. In addition, since the folding paper Pc is formed on the attachment part 3, almost no human movement or operation is required to obtain the folding paper Pc, and the effect is extremely useful especially for elderly people. It will be something.
