Abstract

In apparatus for winding toilet paper 1 into a roll supported by rollers 3A, 3B, the shaft 2 on which the roll is formed is in two sections releasably joined at 2A, 2B. When the roll is fully wound, the shaft sections are withdrawn in opposite directions by moving plates 6 along rails 7 in direction X. If one section clears the roll before the other, movement of the roll with the other section is blocked by a stop 4. Vertically movable supports 18 lift the now-free roll from rollers 3 for removal from the apparatus, after which the shaft sections are moved back together with supports 18 acting as guides for the approaching sections. <IMAGE>

Description

TOILET PAPER TAKE-UP DEVICE The present invention relates to a device for taking up toilet paper, especially toilet paper rolls without a core.
A conventional toilet paper take-up device is disclosed in Japanese patent application Kokai publication No. 2-193849. In this device, as shown in Figs. 4 to 6 of the hereto attached drawings, a shaft 2 is disposed above a position where rolls 3A and 3B rotatable in the direction shown by an arrow R are provided adjacent to each other.
A material paper having a relatively large width from which toilet paper rolls 1 are taken up is fed between the shaft 2 and the roll 3A as shown by an arrow S, and is taken up on the shaft 2. During this taking-up operation, toilet paper 1 being taken up on the shaft 2 is pressed downwardly by a roll 3C so as to prevent loose winding of the toilet paper 1. Furthermore, in starting the toilet-paper take-up operation, air is sent from between the shaft 2 and the roll 3B as shown by an arrow T so that the leading end of the toilet paper 1 is brought into a tight contact with the outer circumferential surface of the shaft 2.
After a taking-up operation is finished, a cylinder 19 is driven so as to move an arm 21 about a pin 20 to thereby remove toilet paper 1 taken up on the shaft 2 from a take-up device 22 together with the shaft 2. Next, the shaft 2 is pulled out from the taken-up toilet paper by pushing one end of the toilet paper 1 by means of a pusher, and finally the toilet paper is cut into a predetermined width by a cutter.
In this conventional device, when the shaft 2 is pulled out of the toilet paper 1, a great resistance is produced due to the friction generated between the shaft 2 and the toilet paper 1, and on account of this, when the toilet papEr 1 is pushed by the pusher, one end of the toilet paper 1 at which it is pushed by the pusher becomes compressed to undergo deformation. Particularly in the cases of core-less toilet paper rolls 1, a problem is posed that many defectives are likely to be produced.
In addition, it is indispensably required to remove the shaft 2 from the take-up device 22 every time the toilet paper 1 is removed therefrom, and moreover, since the stroke over which the shaft 2 is pulled out is relatively long, the is also a drawback that it takes a long time to carry out a pulling-out operation of the shaft 2.
In view of the above drawbacks of the conventional device, an object of the present invention is to provide a toilet paper take-up device which can prevent the deformation of toilet paper when the shaft is pulled out from the toilet paper, improve the quality and yield of toilet paper, and reduce the time required for the shaft pulling-out operation.
A toilet paper take-up device for attaining the above object according to the present invention is characterized in that it comprises a shaft for taking up toilet paper, which is adapted to rotate circumferentially and can be divided into two in the londitudinal direction thereof at a point in its effective length for the taking up of the toilet paper.
According to the present invention, it is possible to divide one shaft into two shaft members in the longitudinal direction of the shaft, and also to pull out the two shaft members from the ends of toilet paper. Due to this, the stroke over which the shaft is pulled out is made extremely short in comparison with the conventional case. In particular, if the shaft is devided into two at the center in the longitudinal direction thereof, the pullig-out stroke per shaft member becomes a half that in the case of the conventional device.
Thus, since the pulling-out stroke for a shaft member becomes short, friction generated between one shaft member and toilet paper is reduced. In addition, since two shaft members are simultaneously pulled out from the ends of toilet paper, tension is applied to the toilet paper while the two shaft members are being pulled out, whereby deformation of toilet paper due to compressive strain can be prevented. Furthermore, even when one of the two shaft members has been pulled out of the toilet paper and the other shaft member is to be then pulled out, the compressive force to be applied to an end of the toilet paper can be considerably reduced when compared with the case of the conventional device, whereby the toilet paper can be prevented from undergoing compressive strain.
In addition, according to the present invention, it is unnecessary to remove the shaft from the take-up device in removing the toilet paper from the shaft, and since the stroke over which the shaft members are pulled out is short as described above, the time required for the pulling out of the shaft can be reduced to a great extent.
Fig. 1 is a perspective view of a toilet paper take-up device according to one embodiment of the present invention, showing an operation condition in which toilet paper is being taken up on a shaft; Fig. 2 is a perspective view of the device of Fig.
1, showing an operation condition in which the toilet paper has been removed from the shaft; Fig. 3, is an enlarged cross-sectional view of essential parts, taken along the line A-A in Fig. 1; Fig. 4 is a side view of a conventional toilet paper take-up device; Fig. 5 is a front view of the device of Fig. 4; and Fig. 6 is a cross-sectional view of essential parts, taken along the ling B-B of Fig. 5.
As shown in Fig. 1, toilet paper or a toilet paper roll 1 is taken up on a shaft 2 of a take-up device 22. The shaft 2 is so constructed as can be divided into two at the center in the longitudinal direction thereof, and as shown in Fig. 2, a recessed portion 2A and a protruding portion 2B of the shaft 2 are so formed as to be detachably connected to each other by fitting.
Ends of the shaft 2 are set at predetermined positions by means of cylinders 16. In addition, two support devices (rolls) 3A and 3B for supporting toilet paper 1 upwardly are disposed lower to the shaft 2. Guides 18 are provided between the rolls 3A and 3B to prevent the risk of fall of the shaft 2, and these guides 18 are moved vertically by means of cylinders 17.
A motor 9 drives a driving shaft 15 provided with a wheel 10 via a chain 11, and also moves a chain 14 between a wheel 12 provided on the driving shaft 15 and a wheel 13 in one or the other of the directions shown by arrows X and Y.
This movement of the chain 14 then moves an engaging device (plate) 6 accordingly, i.e., either in the direction shown by the arrow X or in the direction indicated by the arrow Y via a bearing 8 provided inside a rail (guide plate) 7, as shown in Fig. 3.
The above plates 6 pull the ends of the shaft 2 towards left and right respectively so as to pull the protruding portion 2B out of the recessed portion 2A, whereby the shaft 2 is divided into two shaft members. These plates 6 are designed to move over a distance required for the pulling out of the shaft 2 from the toilet paper roll 1.
In addition, a securing member (stopper) 4 is mounted on a frame 5 inwardly of the respective plates 6.
This stopper 4 is adapted to be brought into abutment against the end of the toilet paper 1 in which one of the two shaft members still remains present whereas the other member has already been pulled out therefrom, to thereby stop the movement of the toilet paper 1.
Next, the operation of the take-up device 22 will be described. After a predetermined length of material paper has been taken up on the shaft 2 by the take-up device 22 to the form of a toilet paper roll 1, an operation is carried out in which the shaft 2 is pulled out from the toilet paper 1.
The driving shafts 15 are first rotated by driving the motors 9 so as to move the chains 14 in the direction indicated by the arrow X. As the chains 14 move, the plates 6 also move in the direction indicated by the arrow X. When the plates 6 move, the shaft 2 is divided into two shaft members 2, and a shaft pulling-out operation is thus started.
Since the stroke over which each shaft member 2 is pulled out is shorter than that in the case of the conventional device, the shaft members 2 can be pulled out form the toilet paper 1 more quickly. At this time, the two shaft members 2 are pulled out of the toilet paper 1 almost simultaneously.
Even if one of the two shaft member 2 has been pulled out of the toilet paper 1 while the other still remains present therein, the remaining stroke over which such other shaft member has to be pulled is very limited. The end of the toilet paper 1 in which such other shaft member 2 still remains present is prevented from moving in the direction shown by arror W by the stopper 4, and thereafter such other shaft mbmer 2 is also completely pulled out of the toilet paper 1.
The toilet paper completely removed from the shaft 2 is then supported by means of the rolls 3A and 3B. Next, when the cylinders 17 are driven so as to move the guides 18 upwardly, the toilet paper roll 1 is lifted up, and is taken out from a front side end of take-up device 22 after having passed over the roll 3A.
When these operations have completed, the plates 6 are moved in the direction indicated by the arrow Y rotating the motors 9 reversely. As the plates 6 move, the two shaft members 2 then move in the direction indicated by the arrow Y while being guided by means of the guides 18.
Then, the protruding portion 2B and the recessed portion 2A of the shaft members 2 are joined together by fitting, to become in the form of the original shaft 2. Thereafter, another paper take-up operation cycle is started.
According to the present invention, since the stroke over which the shaft members are pulled is relatively short, the friction to be possibly generated between each shaft member and the toilet paper is relatively small. In addition, since the two shaft members 2 are pulled out of the ends of toilet paper 1, deformation likely in the case of a compressive force application is not generated of the toilet paper 1. Therefore, it is possible to improve the quality and yield of the toilet paper 1.
Moreover, according to the present inventoin, since it is unnecessary to remove the shaft 2 from the take-up device 22 when the toilet paper 1 is removed from the shaft 2, and as described above, since the shaft pulling-out stroke is short, the time required for the pulling out of the shaft can be reduced to a great extent.
