Description

[Detailed explanation of the invention] [Purpose of the invention] "Industrial application field" This invention relates to a holding device that pulls out rolls of toilet paper, paper towels, etc. (generally referred to as sanitary paper) as needed. .

``Prior Art'' Rolls of toilet paper and paper towels are commercially available in which wrapping paper is wound around a hollow cylindrical core, which is attached to a holding device and used by pulling out the required amount. In these holding devices, a mandrel is passed through a core of sanitary paper, and the mandrel is detachably attached at both ends to a support fixed to a wall or furniture, etc., and the support has an axis parallel to the mandrel. There is one in which the cover is pivoted. In the case of toilet paper, the wrapping paper attached to such a support is pulled out to a required length, and the end of the cover pivoted to the support is used to manually move the paper in the lateral direction and cut it. In addition, there is a device that cuts the wrapping paper by making the end of the cover into a saw blade shape. Some sanitary paper has perforations to make it easier to cut to a certain length. Some toilet paper holding devices have a roll core fixed to the holding device and draw out the paper roll in an axial direction in a spiral manner.

``Problems to be Solved by the Invention'' In toilet paper, the above-mentioned roll core is held by a mandrel, and both ends of the mandrel can be attached to and removed from supports. However, with this type of toilet paper holding device, when the roll is pulled out, the core loosely fitted in the mandrel moves, causing the roll to dance and the cover to move up and down, making a clicking sound. can be heard by people outside the toilet. Even if you try to cut the rolling paper to the right size, it is quite difficult to cut it regularly and the result is unsightly. If the paper roll were to be successfully cut, the cut end would touch the side of the roll, and the next user would have to rotate the toilet paper on the mandrel unnecessarily in order to find the position to pull it out. Because it is thin, it is difficult to find the cut and difficult to pull out.

A holding device that pulls out toilet paper rolls in the axial direction operates quietly, but because the paper rolls are in a spiral shape, it is limited to paper that has a certain stiffness, and moreover, it makes awkward movements when pulling out the rolls. My hands don't feel good because of this,
You have to stretch the paper again to bundle it.

In the case of paper towels, rolls are cut to a certain length. In this holding device, the mandrel is inserted into the winding core and the mandrel is detached from the holding device, similar to toilet paper. Alternatively, there are devices in which the holding device is provided with a dowel that can be fitted onto the winding core. When pulling the end of the paper towel roll with such a holding device, if you do not pull it in a very horizontal direction, the end of the paper towel roll will come out following the cut you are trying to cut. If you pull it out, it will stick out for a long time without being cut, and cutting it requires skill no matter what method you use.
Perforated toilet paper has the same problems as paper towels.

This invention solves the problems of the conventional roll-shaped sanitary paper holding device mentioned above, and provides a roll-shaped sanitary paper holding device that can cut even uncut paper into a certain length, is simple to operate, and is quiet during operation. The purpose is to

[Structure of the idea]

``Means for solving the problem'' This idea consists of a frame placed on the side of the roll of sanitary paper, which has a detachable mandrel that holds the roll of sanitary paper;
A paper feed roller fixed to a paper feed roller shaft pivoted on the frame in parallel with a shaft attached to the frame, a paper feed pressure roller in pressure contact with the paper feed roller, and a shaft parallel to the paper feed roller axis form the frame. a lever pivotally connected to the lever; an intermittent feeding device disposed between the lever and the paper feed roller axis for intermittently sending the movement of the lever in one direction; and an intermittent feeding device disposed between the lever and the paper feed roller shaft for magnifying the movement of the lever. A roll of sanitary paper comprising a speed increasing device disposed between the shafts, a paper guide member provided between a pair of paper feed rollers and an exit of the device, and a cutting device operated by the lever provided on the exit side of the device. It is a holding device.

"Operation" When the lever is rotated, the paper feed roller shaft is intermittently rotated in one direction by the intermittent feed device, and the rotation angle of the lever is expanded by the speed increasing device and transmitted to the paper feed roller shaft. A roll of sanitary paper is fed on a guide member by a pair of feed rollers, and is fed out between cutting devices on the exit side of the device. When the lever is rotated to the cutting device, the lever engages the cutting device and the web is cut. The lever 11 can be returned to its original position by means of an intermittent feed mechanism.

Feed pawls 15 made of pins are press-fitted into the drive pulley 9 at positions where they engage with the pawl ends of the ratchet pawls 14, with their circumferences equally spaced. A ratchet pawl stop 16 is fixed to the lever 11 so as to come into contact with the rear end side of the ratchet pawl 14. One end of a tension spring 17 is locked to the rear end side of the ratchet pawl 14 in order to keep the ratchet pawl 14 in constant contact with the ratchet pawl stop 16, and the other end of the spring 17 is engaged with the rear end of the ratchet pawl 14.
It is locked to. A torsion spring 44 is inserted into the fixed shaft 5, one end of the torsion spring 44 is locked to the stand 4, and the other end of the spring 44 is locked to the lever 11. It is rotated clockwise until it hits the stopper 30.

A paper feed roller shaft 18 is pivotally attached to the side plates 2 and 3 in parallel to the mandrel 8, and a small diameter feed pulley 19 is fixed to the end of the paper feed roller shaft 18 extending outward from the side plate 2. . Drive pulley 9 and feed pulley 19
An endless rubber belt 21 with a circular cross section is wound between them. A paper feed roller 20 is fixed to the paper feed roller shaft 18 .

At a position directly above the paper feed roller shaft 18, a notch 22 is provided from the end of each of the side plates 2 and 3, and a paper feed pressure roller shaft 24, on which a paper feed pressure roller 23 is pivotally mounted, is provided in the notch 22. It is inserted so that it can come in and out freely, and the paper feed pressure roller 23 is inserted into the paper feed roller 2.
It is in pressure contact with 0.

A paper guide plate 43 is fixed at both ends to the side plates 2 and 3 and extends from near the nip portion where the paper feed roller 20 and the paper feed pressure roller 23 are in pressure contact to the paper outlet 25. Following the paper outlet 25 as shown in FIG.
6 is provided. The cutting device 26 has a lower blade 27 fixed to the side plates 2 and 3, and a lower blade 27 at the end of the lower blade 27.
The upper blade 29 is pivotally connected by a pin 28 fixed to the pin 28, and a torsion spring 45 is inserted into the pin 28.
One end of the torsion spring 45 is locked to the pin 28, and the other end of the spring is locked to the upper blade 29, urging the upper blade 29 counterclockwise in FIG. As shown in FIGS. 1 and 2, the lower blade 27 and the upper blade 29 are arranged so that one side of the plate surface is in contact with each other, and shearing cutting blades 31 and 32 are provided. A stopper 33 that abuts the upper blade 29 is integrally formed on the side plate 2 so that the interval between the shearing blades 31 and 32 is as narrow as possible.

When the roll 36 of the toilet paper 34 has been used, the core 35 remains on the mandrel 8. When the mandrel 8 is pulled outward from the side plate 3 side, the mandrel 8 and the mandrel support ring 6 are disengaged, and the mandrel 8 can be taken out through the hole 7 in the side plate 3. Take out the winding core 35,

is pulled out, the mandrel 8 is inserted through the hole 7, passed through the winding core 35, and the tip of the mandrel 8 is pushed into the mandrel support ring 6.

When the paper feed pressure roller 23 is lifted, the paper feed pressure roller shaft 24 escapes from the notch 22, so that the paper feed pressure roller 23 can be taken out of the apparatus. The end of the paper wrapper 36 is stretched out, passed through the paper outlet 25 from the paper guide plate 43, and passed through between the shearing blades 31 and 32 of the cutting device 26, so that the end of the paper wrapper 36 is slightly exposed to the outside. Next, the paper feed pressure roller shaft 24 is inserted through the notch 22, and the paper roll 36 is pressed onto the paper feed roller 20 by the paper feed pressure roller 23.

When the lever 11 is rotated counterclockwise relative to the torsion spring 44 in FIG. 1
Rotation is transmitted to the drive pulley 9 at an increased speed, the feed pulley 19 rotates at an increased speed in the same direction as the drive pulley 9, and the feed roller shaft 18 rotates in the same direction to feed a feed roller with a much larger diameter than the feed pulley 19. The paper roller 18 rotates and feeds the paper wrapper 36 to the left. The wrapping paper 36 passes from the paper outlet 25 along the paper guide plate 43 and exits between the upper blade 29 and the lower blade 27. When the lever 11 hits the end of the upper blade 29, the upper blade 29 rotates around the pin 28 against the torsion spring 45 and descends, and the paper roll 36 is cut by the lower shearing blade 31 and the upper shearing blade 32. Sheared. After this shearing, the lever 1 is
1 is fed, the paper feed roller 20 feeds the paper roll 36 by a short length, so the paper roll 36 reaches the paper outlet 25.
Then, the intermediate portion between the paper feed roller 20 and the paper feed pressure roller 23 sags with respect to the paper guide plate 43, as shown by the two-dot chain line 36' in FIG.

When the lever 11 is rotated clockwise in FIG. 1 about the fixed shaft 5 and returned, the torsion spring 44 assists the rotation of the lever 11. When the lever 11 returns, the upper blade 29 rotates about the pin 28 and rises due to the torsion spring 45. When the upper blade 29 rises, the portion of the wrapping paper 36' that has been sagging and curved until now extends and the end of the wrapping paper 36 peeks out from between the shearing blades 31 and 32. When the lever 11 is returned, the ratchet pawl 14 hits the feed pawl 15, and as shown in FIG.
It rotates counterclockwise against the pressure and passes through the feed pawl 15 portion. At this time, the tension spring 17 is given a gentle spring force so that the roll 36 of the toilet paper 34 is not rewound. Lever 11 is stopper 3
It hits 0 and stops.

If you want to take out the paper roll 36 for a long time, rotate the lever 11 close to the cutting device 26, return it without touching the upper blade 29, and repeat the process of rotating the lever 11 in the direction to pull out the paper roll 36 again until the paper roll is at the desired length. When this happens, the lever 11 is used to hold down the upper blade 29.

FIG. 5 is a side view showing an example of the case where it is attached to a wall. The base 1 is in contact with the wall 38 and is attached using a screw member using the attachment hole 37 of the base. In such a case, the notch 22 into which the paper feed pressure roller shaft 24 is inserted is provided obliquely.

In the embodiment, the rotation of the lever 11 is controlled by the paper feed roller shaft 18.
A winding transmission device was used to convert the rotation into
It may also be based on chain conduction or gear train.

In the embodiment, the mandrel 8 that supports the toilet paper 34 is coaxial with the fixed shaft 5 to which the drive pulley 9 and the lever 11 are pivoted, but the fixed shaft 5 is not used and the mandrel 8 is the same in different parts from the fixed shaft 5. It may also be supported.

In the embodiment, a ratchet mechanism is used as an intermittent feeding device between the lever 11 and the drive pulley 9, but the drive pulley and the lever 11 may be connected via a one-way clutch. Alternatively, the drive pulley 9 and the lever 11 may be fixed, and a one-way clutch may be interposed between the paper feed roller shaft 18 and the feed pulley 19.

In the embodiment, the lever 11 is manual, but as shown in FIG.
A pulley 39 is attached to the boss part of 1, and the pulley is connected to an electric motor 42 fixed to the side plate 2 by a winding transmission device 41, and a switch (not shown) is pressed by the upper blade 29 when the cutting device 26 is operated. An electric motor 42
A control device is provided to stop the electric motor 42 by a switch (not shown) that operates when the lever 11 touches the stopper 30 and to set the electric motor 42 to a forward rotation preparation position, and is started by push button operation. You can do it like this.

The cutting device 26 has shearing blades 31 and 32 that face each other over the entire width of the wrapping paper 36, and moves the upper blade 29 and the lower blade 27 so as to alternate so as to pass the wrapping paper 36 between them. The moving distance of the blade 29 is also small, which is preferable.
A method of cutting the wrapping paper by rapidly moving a slider inserted into the wire from the outside in the width direction of the wrapping paper 36 along the wire, a method of cutting the wrapping paper with a roller cutter, etc. using electric power. You may also do so. In the case of such a power cutting device, the lever 11 is used to push the start switch of the cutting device to operate it.

The above embodiments have been described for toilet paper, but the same applies to paper towels and rolled kitchen paper, and in the case of paper towels and kitchen paper, there is no need to make cuts in the wrapping paper.

[Effects of the invention] This invention provides a pair of paper feed rollers parallel to the shaft that holds the rolled sanitary paper, a guide plate for the paper roll from the pair of paper feed rollers to the exit of the device, and a cutting device provided on the exit side of the device. Because of this, the rolled paper passes through a fixed path, and since there is no cover of rolled sanitary paper unlike the conventional example, it is quiet during operation. The cutting device can be complete so that the cuts in the paper wrapper are precise and straight. A lever is pivotally attached to a shaft parallel to the paper feed roller shaft to which the paper feed roller is fixed, and the rotation angle of the lever is expanded through an intermittent movement device and a speed increase device that can rotate in one direction from the lever to feed paper. The signal is transmitted to the roller shaft, and the cutting device is activated by the rotation of the lever after the paper is fed. By appropriately selecting the speed increase ratio of the speed increase device and the diameter of the paper feed roller, the full swing of the lever can be controlled. This allows the appropriate wrapping paper to be cut and output, and even when the desired length of the wrapping paper is long, it can be handled.

As described above, according to this invention, a fixed length of paper is regularly cut with quiet operation.
