The air blowing device 40 is a device for preventing the base paper from sticking out and is useful for biting the base paper into the portion that is in contact with the winding drum 1. The outlet 40b is directed toward the region where the core 14 is in contact with the winding roll 4, and the base end 4
0a is fixed to the machine frame 2, and the base paper extrusion prevention device is provided with a free bearing frame 16 whose base end is pivoted around the shaft 5 of the winding roll 4 as a fulcrum, as described above. The presser roll 15 is rotatably supported by the end, and the distance B between the presser roll 15 and the take-up roll 4 is made as narrow as possible, especially within the range where they cannot roll into contact with each other. It is made up of configurations. The presser roll 15 of this embodiment has a gear 73 fitted to its shaft end, an idle gear 74 pivotally supported by the bearing plate 16a, and a gear 75 fitted to the shaft 5 of the winding roll 4. The presser roll 15 is interlocked and connected to the take-up roll 4 via the
is the first winding roll at the same peripheral speed as the winding roll 4.
It can be rotated clockwise in the figure.

The winding device of this embodiment has a lower winding space.
A device for discharging the thickly wound log 43 from _the receiving roll 25 to the outside of the winding space A ₂ is provided.
It also includes an air cylinder 30 connected to the bearing frame 26 of the receiving roll 25, and a log 43.
However, when the log is thickened in the lower winding space _A2 , if the receiving roll 25 is suddenly moved downward, the thickened log 43 is supported by the receiving roll 25 on the left side of its center of gravity. , by the rotation (inertia) of the receiving roll 25, it is ejected to the right.

A temporary log holding device for stopping the rotation of the log 43 released from above the receiving roll 25 and temporarily holding it in a stationary state is provided in the lower winding space A. However, in _this embodiment, the temporary log holding device is supported by the machine frame 7 and placed at a suitable location in the front lower part of the lower winding space _A2 . The disposed receiving plate 44 and the bearing frame 7 of the winding roll 4
It is also configured with a plurality of presser plates 46 that protrude from a shaft 45 that is supported at a suitable position on the top.
It is configured to be able to freely appear and retract downward from the position shown in the figure. An air cylinder 42 for operating the free end side of the presser plate 46 is connected to the presser plate 46.

In addition, in the figure, 47 is a paper which has been rolled thickly by the winding device of this embodiment and has been cut off.
The log discharge conveyor 48 is a receiving roll disposed at a constant interval in front of the conveyor 48. Also, 5
0 was attached to the winding device of this example. A perforation device 50 includes a cutter roll 52 on which a cutter 51 for making perforations is implanted on its cylindrical surface, and a fixed blade 54 attached to a mounting body 53 fixed to the machine frame 2. However, when the paper 56 fed out from the base paper roll 55 comes into contact with the cutter roll 52 and is sent to the winding device, the cutter 51
However, a perforation can be made at the position where it hits the fixed blade 54. 57 is a guide roll.

Next, to explain the operation, since the paper winding device according to the present invention has the above-mentioned configuration, in the device of the above embodiment, the winding drum 1 and the winding roll 4 are kept at the same circumferential speed. At the same time, when the eccentric wheel 11 and the shaft 13 to which the grooved cam 24 are fitted are started at a certain timing and rotated once intermittently, the winding space is rotated. The distance between the winding drum 1 and the winding roll 4 that constitute A increases and decreases intermittently at a substantially constant cycle, and the presser roll 15 intermittently moves up and down at the same cycle. Therefore, the eccentricity of the eccentric wheel 11, the cam shape of the grooved cam 24, and the phase relationship between the two are appropriately set, and at a certain time synchronized with the above-mentioned period, the receiving roll 25 is rotated. If the air cylinder 30 connected to the bearing frame 26, the air cylinder 42 connected to the presser plate 46, and the air blowing device 40 are operated, and the air cylinder 116 is operated, the air cylinder 116 is moved into the winding space A. One core 14 is supplied every cycle, and the base paper 56 is wound around the core 14 in the following manner.

That is, as described above, when the stopper 38 is opened when the presser roll 15 is positioned at the uppermost point and the distance between the winding drum 1 and the winding roll 4 is the narrowest, the cores will fall from the supply device 31. The core 14 is rotated in the direction of the arrow in contact with both the winding drum 1 and the winding roll 4.

In this state, when the presser roll 15 is lowered, the core 14 is moved onto the winding drum ₁ by the presser roll 15 in this upper winding space A1.
It is brought into pressure contact with the partner of the take-up reroll 4, and is reliably rotated. At this point, the gluing device 100 has its gluing head 103
is in a diagonally upward position (dash line position in Figure 6),
It is not exposed between the winding rolls 4 and does not touch the core 14 (FIG. 7).

Starting from the above state, the base paper 56 which has now passed through the perforation device 50 and the guide roll 57 is brought into contact with the winding drum 1 and fed between the winding drum 1 and the core 14. ,
Winding drum 1 and core 1 at the leading end of base paper 56
Gluing device 1 is synchronized with the feed into the 4 spaces.
When 00 is rotationally displaced, that is, in the case of the embodiment, the air cylinder 116 is caused to contract,
When the gluing head 103 is moved to an obliquely downward position (the position indicated by the chain line in FIG. 6), at this time, the gluing head 103 of the gluing device 100 moves as it passes through the solid line position in FIG. is exposed between the winding rolls 4 and comes into contact with the surface of the core 14 which is maintained in the above state (FIG. 7). Therefore, on the circumferential surface of the core 14 which is rotating at high speed, At this time, the glue is applied along the circumferential direction by the glue application head 103. In this case, the amount of glue applied is
In the case of the embodiment, when the amount of glue supplied is controlled by the solenoid valve 106 and the air pressure for operating the air cylinder 116 is controlled, the circumferential length of the applied portion and the unit area at the applied portion are controlled. You can freely select and adjust the amount of glue applied. Further, the areas where the glue is applied in the longitudinal direction of the core 14 and the distance between the areas where the glue is applied can be arbitrarily determined by appropriately selecting the width and position of the rolls constituting the winding roll 4 and the number of rolls. The width of the glue application can be arbitrarily designed depending on the width of the glue application head 103.

When the base paper 56 is fed between the winding drum 1 and the core 14 at the above position in the above manner, the glue applied on the surface of the core 14 at appropriate intervals in the longitudinal direction is Since it faces the annular groove 120 formed in the presser roll 15 and does not contact the surface of the presser roll 15,
The core 14 reaches the part of the winding drum 1 where it comes into contact with the base paper 56, and there it acts as an adhesive for the first time on the surface of the base paper 56, and the base paper 56 is adhered to the part of the core 14 that is coated with glue. , winding space
At A ₁ , the base paper 56 is wrapped around the lower surface of the core 14 , passes through the portion where the core 14 is in rolling contact with the take-up roll 4 and the presser roll 15 , and then wraps around the base paper 56 .
The tip end of the wire is to be wound securely around the core 14.

In addition, if the spraying device 40 is provided as an auxiliary device as in the embodiment, there may be a slight delay in the timing of applying glue to the core 14, and as a result, the beginning of the stump of the base paper may be delayed. Even if some length of the base paper 56 is not glued onto the core 14, by operating the spraying device 40, the tip of the base paper 56 will be glued and the core will be attached to the take-up roll 4. This has the advantage that it can be reliably fed to the area where the roll is in contact and wound around the core, and as in the embodiment, the distance B between the presser roll 15 and the take-up roll 4 can be adjusted in particular. When the design is narrow, the presser roll 15 is the first,
Since it is rotating clockwise in Figure 6, the core 14
The stump of the base paper 56 that is wound around the core 14 and guided upwardly between the core 14 and the take-up roll 4 will not be glued to the core 14 even if some length of the stump is not glued to the core 14. Since it cannot pass through B, the advantage is that the cut end of the base paper 56 can be reliably fed to the area where the core 14 is in rolling contact with the presser roll 15 and then wound around the core 14. can get. However, according to the present invention, the spacing between each gluing device 100, the quality of the glue,
As long as the timing of gluing is set appropriately, the above-mentioned auxiliary device is not necessarily necessary, and the scrap (tip) of the base paper 56 will be covered only by the glue applied to the core 14. Therefore, it goes without saying that it is possible to securely wind the base paper 56 around the core 14 and start winding the base paper 56 in the winding space.

In this way, the core 14 with the base paper 56 wound thereon is in the upper winding space _A1 .
The winding drum 1, the winding roll 4, and the presser roll 15 are in contact with each other and are held between them, and the winding is reliably thickened, but at the time of starting, the clutch is not inserted. , said shaft 13
If the core 14 is rotated once, the device of the present invention will rotate the winding drum 1 as the core 14 becomes thicker.
The distance between the paper 56 and the winding roll 4 is gradually increased, and the presser roll 15 is gradually lowered. When the distance between the drum 1 and the winding roll 4 becomes large, the log 43 is moved from the upper winding space A ₁ to the lower winding space A ₂ and brought into rolling contact with the receiving roll 25. It turns out. Later, log 43
is continuously kept in pressure contact with both the winding drum 1 and the winding roll 4 from below (FIG. 8).

And the log 43 is in the lower winding space _A2 ,
Once the winding is sure to thicken, the air cylinder 116 is extended and the gluing device 100 returns the gluing head 103 to the waiting position shown in FIG. 9. Subsequently, the winding roll 4 is brought closer to the winding drum 1, the distance therebetween is returned to the starting point smaller than the diameter of the core 14, and the presser roll 15 is raised. When the presser roll 15 reaches the upper limit, the next core 14 is supplied to the upper part between the winding drum 1 and the winding roll 4. Presser roll 15
is lowered again and returns to the starting position, and the core 14 is in the winding space.
As mentioned above, it is in a state where it is allowed to rotate.

As shown above, the log 4 on the receiving roll 25
3 winds up a predetermined length of paper (FIG. 9), it is detected by a detection means (not shown) and the air cylinder 30 is activated. roll 2
5 is forced to fall rapidly. When the receiving roll 25 is lowered, the log 43 released from the rolling contact between the winding drum 1 and the winding roll 4 is ejected in the rotational direction of the receiving roll 25, that is, forward, and is released onto the receiving plate 44. However, almost at the same time as the air cylinder 30, the air cylinder 4
If configured to activate 2, log 4
3 falls onto the receiving plate 44, and at the same time, the holding plate 4
6 and is held between the receiving plate 44 (FIG. 10).

In the apparatus of the embodiment, when the above state is reached, the thickly rolled log 43 is connected to the receiving plate 44 and the holding plate 4.
The rotation of the log 43 is stopped by the temporary holding device consisting of 6, and the log 43 is held stationary. 56
continues to be fed into the winding space A below the core 14.

Therefore, when the detection means detects the winding of a predetermined length of paper, the air cylinder 116 is actuated in a timely manner based on a signal from the detection means;
By displacing the gluing device 100, the core 1
4 (FIGS. 6 and 10), the upper end of the base paper 56a that is loose in the winding space A is glued to the core 14 waiting in the upper winding space _A1 in the same manner as described above. But it will be glued and wrapped. In this way, when the base paper is wound around the waiting core 14 in the upper winding space _A1 , the portion 56a of the base paper that has been hanging below the core 14 is put under tension. In this case, the cut will be automatically made at the perforated area. That is,
At this time, the rolled log 43 is rolled into a roll base paper 55.
The base paper 56 that is separated from the roll base paper 55 and follows the roll base paper 55
Winding onto a new core 14 is started. The clutch is engaged with the one-rotation shaft 13 at this point.

Note that the paper separation position using the mechanism in the above embodiment is determined by detecting the perforation position.
By setting the operating time of the cylinder 30 and setting the shaft 13 to intermittently make one revolution from the starting point, the winding device of the present invention can always produce a predetermined length of paper. can be wound.

If the presser plate 46 is raised in synchronization with the shaft 13 after the paper has been cut as described above, the log 43 will roll on the conveyor 47 and its tip and It is once received between the front receiving rolls 48.

Therefore, while the log 43 is received at the above-mentioned position, an arbitrary gluing device (not shown) is used to apply glue to the appropriate place on the paper that was rewound while the log 43 was rolling to the position. If so, this log 4
3, while rotating in the direction of the arrow at the above position, the cut end of the paper is wound up and pasted into a log.

Although one embodiment of the paper winding device of the present invention has been described above, the present invention is not limited to the embodiment described above. Although an example has been shown in which the roll 15 is connected to a drive source and the receiving roll 25 is freely rotatable, in other embodiments, on the contrary, the receiving roll 25 is connected to a driving source,
The presser roll 15 may be configured to freely rotate by driving its circumferential surface at the same peripheral speed as the winding drum 1 and the winding roll 4. Whether it is configured or forcibly driven is an arbitrary matter. Further, the air blowing device provided in the above embodiment is merely an auxiliary device, and is not essential to the present invention, and its use in combination is optional.

Further, in the above embodiment, the gluing device 10
Wind up the mounting frame of 0 and the bearing frame 7 of the roll 4.
Although an example is shown in which the mounting frame 101 is fixed to the bearing frame 7, in other embodiments, the base end of the bearing frame 7 is pivotally supported by a shaft horizontally suspended in the bearing frame 7, although not shown. The gluing device may be attached to the tip of the mounting frame whose intermediate portion is supported by the screw 108 and the links 111, 112, etc. in the above embodiment. Although the retraction and retraction control is performed from between the rolls of the take-up roll, in other embodiments, control may be provided via a push-pull wire, and in other embodiments, a solenoid may be used to operate the gluing device to retract and retract. You may let them.

As will be understood from the above explanation, according to the winding device of the present invention, the winding space is is formed, and the winding space is divided into upper and lower winding spaces with a line connecting the axes of the winding drum and the winding roll as the border, and in the winding device of the present invention, The core is intermittently supplied to the upper winding space, and while moving from the upper winding space to the lower winding space, these two locations are used to continuously unwind the core without stopping. Each of the above-mentioned winding spaces is configured such that all three rolls, other than the winding drum, can be displaced, and the winding space is In addition, in each of the upper and lower winding spaces, three of the four rolls or drums mentioned above are always in rolling contact with the core or log, and are clamped at three points. Since the winding is performed and the core is moved under this condition, the winding is performed extremely smoothly and reliably.

Further, in the winding device of the present invention, the winding is carried out in the lower winding space on a movable receiving roll, and the log that has been rolled and thickened in the space can collect a predetermined amount of paper. When winding is performed, the receiving roll is lowered to release the log from the winding space, and the next step of the base paper that is separated from the log or is separated from the log is carried out. The winding around the core is carried out by the gluing device as described in detail with reference to the embodiments, with the winding drum, the winding roll, and the presser roll being clamped at three points. The winding operation can be easily and reliably carried out without interrupting the winding operation, that is, without interrupting the unwinding of the base paper.

That is, in the apparatus of the present invention, in particular, the presser roll is constituted by a roll having a plurality of annular grooves at appropriate intervals on its surface, and the device for winding the base paper around the core is arranged in the presser roll. A surface of a core disposed in the same phase as each of the annular grooves in the axial direction and facing the core that is in rolling contact with the winding drum winding roll and presser roll at the upper part of the winding space. When the above-mentioned gluing device applies glue to the surface of the core which is rotating at the winding standby position, the core coated with glue is coated with glue. The surface will be bonded to the base paper between the winding drum, and the base paper wound around this core will be glued at or near the leading end of the base paper at multiple points at appropriate intervals in the width direction of the base paper. It is bonded to the core and wrapped around the surface of the core, making it extremely smooth and reliable. In addition, with the device of the present invention, glue can be applied to the surface of the core that is rotating in the winding standby position without having to separate the base paper from the thickly rolled log. If perforations have been made in the base paper, by gluing the base paper that follows the thickened log to the core in this standby position, in other words, the core is attached to the base paper between this core and the thickened log. By applying tension generated by the rotation of the log, the base paper between the thickened log and the core can be automatically cut at the perforated area.

Further, since the presser roll has an annular groove formed on the roll surface that is in the same phase as the installation position of the gluing device in the axial direction, the glue applied to the surface of the core by the gluing device can be removed. It does not stick to the surface of the presser roll.
Therefore, any glue applied to the surface of the core serves only to adhere the base paper to the core as it is, and does not cause problems such as those caused by the base paper adhering to the surface of the presser roll.
