1, and the second winding device is constructed as follows.

That is, the details of the belt 41 of this embodiment are shown in the third to fifth sections.
To explain the figure, the presser roll 15 is mounted on a bearing 15.
The bearing frame 16 shown in a is comprised of a pair of bearing plates 416a, 16a (only one side shown) rotatably supported on the shaft of the presser roll 15 on both sides of the take-up roll 4, and this pair of bearing plates. Two stays 16b connecting between 16a and 16a

A spring 12 for tensioning the belt 41 is arranged between them. In this way, the belts 41, which are wound around between the pulleys 71 and the presser rolls 15 as described above, are positioned in the spaces between the winding rolls 4, 4, respectively. This belt 41 is attached to the presser roll 15
However, in the position shown in FIGS. 1 and 5 where it acts on the core 14 in the upper winding space A1 from above, the arm rod 7-0 and the belt 41 The length is set. Further, the presser roll 15 is connected to 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 operatively connected to the take-up roll 4.
The belt 41 is always rotated clockwise in FIGS. 1 and 5 at the same circumferential speed as the take-up roll 4. In the winding device of this embodiment, a device for discharging the log 43 rolled thickly in the lower winding space to the outside of the winding space A2 from above the receiving roll 25 is installed in the bearing frame 26 of the receiving roll 25. The log 43 is connected to the lower winding space A.
2, when 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, and the rotation of the receiving roll 25 (inertia) ) so that it is emitted to the right.

The lower winding space A3 is 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. However, in this embodiment, the temporary log holding device is supported by the machine frame 7 and is disposed at an appropriate location in the front and lower part of the lower winding space A2. It is composed of a receiving plate 44 which is attached to the winding roll 4, and a plurality of holding plates 46 that protrude from a shaft 45 that is supported at a suitable position on the bearing frame 7 of the winding roll 4. It is configured to be able to freely protrude and retract downward from the gap between the rolls 4 (the position shown in Figures 1 and 5).

An air cylinder 42 for operating the free end side of the presser plate 46 is connected to the presser plate 46. In the figure, 47 is a conveyor for discharging logs that have been rolled up by the winding device of this embodiment and the paper has been cut off.
Reference numeral 8 denotes a receiving roll arranged at a constant interval in front of the receiving roll.

Reference numeral 50 denotes a perforation device attached to the winding device of this embodiment. and a fixed blade 54 attached to a mounting body 53 fixed to the machine frame 2, so that the paper 56 fed out from the base paper roll 55 comes into contact with this cutter roll 52 and passes through the winding device. When you are sent to
A perforation is made at the position where the cutter 51 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. , the eccentric wheel 11
The eccentricity of the grooved cam 24, the cam shape of the grooved cam 24, and the phase relationship between the two are set appropriately, and at a certain time synchronized with the above-mentioned period, the cam is connected to the bearing frame 26 of the receiving roll 25. the air cylinder 30, the air cylinder 42 connected to the presser plate 46, and the air nozzle 40,
Further, when the core supply device 31 is operated, one core 14 is supplied to the winding space A in each cycle, and the paper 56 is wound around the core 14 in the following manner.

That is, as described above, when the presser roll 15 is located at the uppermost point and the distance between the winding drum 1 and the winding roll 4 is the narrowest, the stopper 35 is in the open state, so that the core The core 14 dropped from the supply device 31 contacts both the winding drum 1 and the winding roll 4 and is rotated in the direction of the arrow.

2. In this state, when the presser roll 15 is lowered, the core 14 is moved to the presser roll 15 and the belt 4 suspended around the roll 15 in this upper winding space A1.
1, the winding drum and the winding roll 4 come into pressure contact with each other, and are surely rotated in contact with each other (Figs. 5 and 6). Starting from the above state, the paper 56 that 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. When the air nozzle 40 of the first winding device is operated, the leading end of the paper 56 unwound from the base paper roll 55 is first moved to the area where the core 14 is in rolling contact with the winding roll 1 through the air nozzle 40. It is blown by the action of the core 14, wraps around the core 14, passes between the contact points between the two, and is sent upward. Subsequently, the second winding device
The rotation of the belt 41 feeds the core 14 to the area where it is in rolling contact with the belt 41, and thus the leading end of the paper 56 is reliably wound around the core 14. In this way, the core 14 with the paper 56 wound thereon is connected to the winding drum 1, the winding roll 4, and the presser roll 15 in the upper winding space A1.
It is in contact with the four parts of the belt 41 and is held between these parts, and is surely rolled up, but if the clutch is engaged and the shaft 13 is rotated once at the starting point, this In the device of the invention, as the core 14 becomes thicker, the distance between the winding drum 1 and the winding roll 4 is gradually increased by 5, and the presser roll 15 is
is gradually lowered, and when the distance between the winding drum 1 and the winding roll 4 becomes larger than the diameter of the log 43 on which the paper 56 is wound around the core 14,
The log 43 is moved from the upper winding space θA1 to the lower winding space A2, and is brought into rolling contact with the receiving roll 25.

Thereafter, the log 43 is continuously kept in pressure contact with both the winding drum 1 and the winding roll 4 from below (FIG. 7). In this way, log 46
is reliably rolled up in the lower winding space. During this time, the winding roll 4 is brought closer to the winding drum 1, and the distance between them is made smaller than the diameter of the core 14. , the presser roll 15 is returned to the starting point, and when it reaches the uppermost point, the presser roll 15 moves the next core 14,
It is supplied to the upper part between the winding drum 1 and the winding roll 4,
The presser roll 15 is lowered again and returned to the starting position, and the core 14 is brought into a state in which it is allowed to rotate as described above in the upper winding space.

As described above, when the log 43 on the receiving roll 25 winds up a predetermined length of paper (FIG. 8), this is detected by a detection means (not shown) and the air cylinder 30 is activated. However, when the air cylinder 30 is activated, the receiving roll 25 is suddenly lowered, and when the receiving roll 25 is lowered, the winding drum 1 and the winding roll 4 are released from the rolling contact state. The log 43 is ejected in the direction of rotation of the receiving roll 25, that is, forward, and
However, if the air cylinder 42 is activated almost at the same time as the air cylinder 30, the log 43 will fall onto the receiving plate 44 and be held down by the holding plate 46 at the same time. between it and the receiving plate 44,
It will be in a clamped state (Figure 9).

In the above state, the thick rolled log 43 becomes
A temporary holding device consisting of a receiving plate 44 and a holding plate 46 stops its rotation and holds it stationary.
In this way, even while the log 43 is held stationary, the paper 56 fed out from the base paper roll 56 is kept on the core 1.
At this time, when the air nozzle 40 is activated, the upper end 3 of the portion 56a of the paper that overlaps in the winding space A is moved as described above. By the action of the air blown out from the air nozzle 40, the core 14 that is waiting in the upper winding space A1 is wound.

In this way, when the paper wraps around the core 14 waiting in the upper winding space A1, the portion 56a of the paper that is hanging below the core 14 is put under tension. It will automatically be cut at the part where it is opened. In other words, the thick log 43 is
At this time, it is separated from the roll base paper 55, and the roll base paper 5
Winding of the paper 56 subsequent to 6 on a new core 14 is started. At this point, a clutch is engaged with the one-rotation shaft 13. Note that the paper separation position by the above-mentioned mechanism is determined by detecting the position of the perforation, setting the operating point of the cylinder 30, and intermittently causing the shaft 13 to make one rotation from that point in time. 9, the winding device of the present invention can always wind up a predetermined length of paper.

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

Therefore, while the log 43 is received in the above-mentioned position, an arbitrary gluing device (not shown) is used to place the paper unwound while the log 43 is rolling to that position into place. In the case of gluing, this log 43 is such that the cut end of the paper is wound up and pasted onto the log while rotating in the direction of the arrow at the above-mentioned position.

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. For example, in the above embodiment, Although an example has been shown in which the receiving roll 25 is freely rotatable, in other embodiments, this roll 25 is connected to a drive source and its peripheral surface is connected to the winding drum 1 and the winding roll 4. The bearing frame 7 of the take-up roll and the bearing frame 16 of the presser roll may be driven at the same circumferential speed, and in other embodiments, the displacement actuating mechanism may be modified as follows. It can also be implemented by

That is, the displacement actuating mechanism of the bearing frame 7 of the winding roll 4, as shown in FIG.
The air cylinder 61 is connected to the winding drum 61 so that the spring 60 biases the winding drum 1 in the direction of narrowing the gap between the winding drum 1 and the winding drum 1, and this biasing force can be reduced or reduced by the air pressure connected to the air cylinder 61. In the bearing frame 7,
It may simply be provided with a stopper 62 opposite to the stopper 62 for stopping the urging by the spring 60 when the interval becomes a constant interval smaller than the outer diameter of the core 14. As shown in FIG. 10, the displacement actuation mechanism of the bearing frame 16 of the presser roll 15 connects the air cylinder 63 to the machine frame 2, and also includes a stopper formed by the piston rod end of another air cylinder 64. 65 and when the air cylinder 63 is minimized,
The presser roll 15 is maintained in an upwardly displaced position,
When the air cylinder 63 is extended to the intermediate position, the bearing frame 1
6 contacts the stopper 65 with the air cylinder ring 64 in the most extended state, and the presser roll 15 contacts the core 14 in the upper winding space A1, gradually contracting the air cylinder 64 and closing the air cylinder 63. Similarly, when the core 14 is gradually expanded further, the core 14 located in the upper winding space A1 is pushed by the presser roll 15 and the winding drum 1
The space between the winding roll 4 and the winding roll 4 is expanded, and the winding roll 4 is pushed down into the lower winding space A2. In this case, the belt 41 constituting the second winding device is attached to the pulley 67 fitted on the rotating shaft 66 and to the appropriate position of the bearing frame 16. The rotating shaft 66 is connected to the drive source of the winding drum 1, and the belt 41 is connected to the drive source of the winding drum 1. It may also be configured to rotate at a circumferential speed. 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 a boundary, 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, it is continuously unwound using these two locations without stopping. The paper is rolled up,
Each of the above-mentioned winding spaces is configured such that all three rolls other than the winding drum constituting the winding spaces are movable, and the size of the winding space is variable. 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 held in three points. Since the winding is performed and the core is moved, 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 the paper is wound, the receiving roll r is lowered to release the log from the winding space, and winding of the paper onto the next core is carried out at three points: the winding drum, the winding roll, and the presser roll. Since it is carried out under clamping, this can be done very easily and reliably, and there is no interruption in the winding operation, and the winding operation can be carried out completely continuously. .

Further, in the winding device of the present invention, the first stage of the device for winding the base paper around the core blows the base paper upward to the portion where the core is in rolling contact with the winding roll, and The first winding device consists of an air nozzle that is inserted between the two rolling contact areas, and the second stage winds the base paper that has been inserted into the rolling contact area around the core. A second belt consisting of a presser roll that rolls into contact with the winding roll from above and a pulley that is disposed in the gap between individual rolls of a large number of rolls that make up the winding roll. In this second stage, the base paper whose path is blocked by the belt is fed between the presser roll and the core by the action of the belt. , which will surely be wound around the core.
