The portion of the third roll 3 that comes into contact with the end surface 5 is formed with four second friction protrusions 23a protruding toward the end surface 5.

First, the medicine packaging paper 16 is placed in the cigarette tube 1 of the present invention.
The method of winding is described below. The cigarette tube 1 before cigarette winding is fixed to the cigarette tube rotation drive shaft 10 of the packaging paper winding device 9. That is, in a state where the engaging portion 6 of the bobbin tube 1 faces the side of the bobbin tube rotation drive shaft 10 and is coaxial, the initial rotation direction is positioned so that the positioning rib 8 is engaged with the positioning groove 11a.

As described above, the bobbin tube 1 is fixedly attached to the bobbin tube rotating drive shaft 10 so that it cannot be pulled out.

At least one round of the medicine wrapping paper 16 is wound around the outer peripheral surface 2 of the cigarette tube 1 by hand.
At the point when friction is obtained between the roller and the roller 6, the wrapping paper wrapping device 9 is started to rotate the paper roll driving shaft 10. As a result, the medicine packaging paper 16 is wound in a roll shape around the cigarette tube 1, and the cigarette winding operation is completed by removing the cigarette tube 1 from the cigarette tube rotation drive shaft 10. At this time, the removal of the cigarette tube 1 is performed by rotating the holding plate 14c holding down the cigarette tube 1 in a direction in which the fixing protrusions 14b are disengaged from the fixing grooves 13b, and the fixing protrusions 14b reach the guide grooves 13a. After
This is performed by pulling out the fixing jig 14 and further pulling out the cigarette tube 1. Through the above steps, the wound paper tube 1 in which the medicine packaging paper 16 is wound in a roll shape is completed.

Next, a method of attaching the cigarette tube 1 wound in the above process to the medicine packaging apparatus 15 will be described below. The end face 5 of the cigarette tube 1 is directed toward the cigarette tube mounting shaft 17,
The screw portion 7 is screwed into the shaft side screw portion 18 by rotating the cigarette tube 1 while holding the disk 23 by hand in such a state that the disk 23 does not rotate in the coaxial arrangement. The distance between the end face 5 and the disk 23 shrinks with the rotation of the cigarette tube 1, and finally the two come into contact. In the abutting state, further add a cigarette tube 1
Is rotated, a force attracting each other is generated therebetween, and this force is concentrated on the first friction protrusion 12 and the second friction protrusion 23a. As a result, frictional force concentrates between the first friction protrusion 11 and the second friction protrusion 23a, and the cigarette tube 1 is fixed to the cigarette tube mounting shaft 17 without slack. At this time, since the end face 5 of the cigarette tube 1 and the disk 23 are kept parallel, the axis of the cigarette tube 1 matches the axis of the cigarette tube mounting shaft 17.

Since the threaded portion 7 of the paper tube 1 has a small number of turns of one turn or more and less than 1.5 turns, as shown in FIG. 8, the threaded portion 7 has an axial threaded portion 18 having the same thread pitch. In addition to the screwing, the screw can be screwed to the axial side screwing portions 18 having different screw pitches as shown in FIGS. The screw pitch values shown in FIGS. 8 to 10 are:
An example is shown for explanation.

As shown in FIG. 11, the fixed cigarette tube 1
Then, one end of the medicine packaging paper 16 is pulled out and attached, and the setting of the cigarette tube 1 and the medicine packaging paper 16 in the medicine packaging device 15 is completed. Along with the operation of the medicine packaging device 15, the medicine packaging paper 16 is pulled out of the cigarette tube 1 and packages medicine (not shown). When the paper has run out, the paper tube 1 is removed from the paper tube mounting shaft 17 and another paper tube 1 around which the medicine packaging paper 16 is wound is used.

Thus, it is possible to provide the cigarette tube 1 that can increase the productivity.

Further, by reducing the number of spiral screw turns of the threaded portion 7 of the paper winding tube 1 to at least one turn and within 1.5 turns,
Even if the shaft side screwing portion 18 of the cigarette tube mounting shaft 17 has a screw pitch different from that of the screwing portion 7 of the cigarette tube 1, the screwing can be performed without any problem. In other words, when there is a difference between the two screw pitches, if the screw engagement is about one turn, this difference can be absorbed, but if the screw engagement is performed two or more turns, the difference is twice as large.
Since it spreads according to the number of turns screwed three times, it cannot be screwed. Accordingly, by reducing the number of turns of the screw portion 7 to one or more turns and within 1.5 turns, the difference in screw pitch between the two is suppressed to about one turn and the screws are screwed together. This makes it possible to provide the cigarette tube 1 that can be attached to the cigarette tube attachment shaft 17 having the pitch shaft side threaded portions 18.

Further, the positioning ribs 8 are provided, and are mounted in such a manner that they are aligned with the positioning grooves 11a on the side of the winding reel rotation drive shaft 10, whereby the initial rotation direction is determined.

It is also possible to obtain a paper roll tube 1 that can be used.

Further, when the paper roll tube 1 is manufactured by injection molding, the engaging rib 6
The occurrence of a dent that may occur on the back surface side on which the protrusions such as a are formed is eliminated. This is particularly important on the outer peripheral surface 2 on which the paper is wound. Since the paper roll 1 having the outer peripheral surface 2 suitable for paper winding without dents can be formed, the paper winding tube 1 can be uniformly wound without dents. It is also possible. Furthermore, since the foamed material on the outer peripheral surface 2 of the cigarette tube 1 leaves traces of the flow of the white material and suppresses the slip of the outer peripheral surface 2, an appropriate resistance can be obtained when the medicine packaging paper 16 is wound. In addition, it is possible to form the cigarette tube 1 that can be easily wound.

Further, the first friction protrusion 12 is provided on the end surface 5 of the paper tube 1 so that the paper tube 1 can be connected to the paper tube mounting shaft 17.
When the screw is screwed onto the disk, a force is generated that presses the cigarette tube 1 against the disk 23. This force is concentrated on the first friction protrusions 12, where the friction generated between the cigarette tube 1 and the disk 23 is generated. Power concentrates. Thereby, it is also possible to provide the wound tube 1 that can be more easily and reliably fixed to the wound tube mounting shaft 17.

Further, since the injection molding groove 2a is provided on the outer peripheral surface 2 of the paper roll tube 1, the injection molding die groove 2a is removed when the screw of the screw portion 7 is removed during the injection molding. The engagement of the engaging projections provided on the mold of the injection molding machine (not shown) prevents the paper tube 1 from rotating and being damaged in the mold. This makes it possible to provide a paper roll tube 1 that is free from any inconvenience in use without deformation of the helical screw of the screw portion 7 and deformation of the outer peripheral surface 2.

According to the packaging paper wrapping device 9 of the present invention, the fixing of the cigarette tube 1 to the cigarette tube rotation drive shaft 10 is performed by the engagement between the engagement rib 6a and the engagement groove 11.

Further, a fixing jig 14 is provided for fixing the bobbin tube 1, and the fixing jig 14 is attached to the bobbin tube rotating drive shaft 1.
By fixing the cigarette tube 1 to 0 so that the cigarette tube 1 cannot be extracted, the holding plate 14c securely fixes the cigarette tube 1. In the attachment and detachment work at this time, the use of a tool is unnecessary, and the attachment of the cigarette tube 1 can be easily and surely performed. It is also possible to do.

According to the medicine packaging apparatus 15 of the present invention, the attachment of the cigarette tube 1 to the cigarette tube attaching shaft 17 is performed by screwing the shaft-side screw portion 18 and the screw portion 7. The use of a tool is not necessary in the work of attaching and detaching the cigarette tube 1, and the attaching and detaching of the cigarette tube 1 becomes easy, so that the medicine packaging device 1 that can reduce the burden on the user as much as possible.
5 can be provided.

Further, since the length L1 in the axial direction of the winding tube mounting shaft 17 is shorter than the length L2 in the axial direction of the winding tube 1, the space 15a for storing the winding tube can be made compact. The packaging device 15 can also be used.

Further, in the medicine packaging device 15, the attached cigarette tube 1 repeats rotation and stop together with pulling out of the medicine packaging paper 16, and at the time of the stop, there is a possibility that the machine will try to rotate more than necessary due to inertia. There is a bush 22
By providing the rotation resistance and providing the rotation, the rotation is stopped without causing the rotation more than necessary, so that the medicine packaging device 15 that can prevent the medicine packaging paper 16 from being loosened can be obtained.

Further, the disk 23 having the second friction projections 23a is provided on the paper winding tube mounting shaft 17, so that when the paper winding tube 1 is screwed onto the paper winding tube mounting shaft 17, the paper winding tube 1
3, the force is concentrated on the second friction projections 23a, and the frictional force generated between the cigarette tube 1 and the disk 23 is concentrated there. It is also possible to make the medicine packaging device 15 reliable.
