As shown in FIG. 2, the automatic paper splicing apparatus 100 includes a parent roll 17A immediately before the paper is completely unwound and a new primary roll 17A.
7B, the protruding portion H of the paper protruding from the old roll 17A to the lead-in paper roll 101.
Is automatically affixed to the leading end t of the new roll 17B conveyed toward the overhanging portion H and spliced. Then, the automatic paper splicing apparatus 100 is configured such that the protruding portion H from the old roll 17A is directed toward the adhesive tape a previously attached to the leading end t of the new roll 17B by the tailoring process.
And a knife 103 that separates the overhanging portion H from the old roll 17A in a state where the overhang portion H is attached to the adhesive tape a. According to this automatic paper splicing apparatus 100, the paper of the old roll 17A is pressed against the leading end t of the new roll 17B by the paper pressing roll 102 and pasted, and further, the paper of the old roll 17A is cut out by the knife 103, thereby joining the paper. Automatically completes. Then, a joint T is formed at the joint portion.

The automatic joint position control mechanism is the same as that shown in FIG.

The automatic joint position control mechanism determines the amount of upper winding by the rotation amount of the first drum 105, and can freely control the joint position in the upper winding based on the obtained amount.

Automatic paper splicing apparatus 1 having the configuration described above
A series of operations from automatic paper splicing to upper winding by the automatic control mechanism 00 and the joint position automatic control mechanism will be described below with reference to FIG. First, the new roll 17B is conveyed toward the overhang portion H at a moving speed of, for example, 1 m / s, and is stopped at a predetermined stop position shown in FIG. Then, the paper holding roll 102
Is moved toward the tip t of the new roll 17B.
Then, the overhang portion H located therebetween is naturally pressed toward the tip t, and is adhered to the adhesive tape a. Further, the knife 103 is moved by moving the knife 103 from one end of the overhang portion H in the paper width direction to the other end. In this way, the paper from the old roll 17A is cut off, and the overhang H is automatically connected to the paper of the new roll 17B. Thus, the paper splicing operation is completed, the paper of the new roll 17B is rewound following the paper of the old roll 17A, and the upper winding operation is continuously performed.

That is, the control arithmetic mechanism detects completion of the splicing by the automatic splicing apparatus 100 by, for example, the operation of the knife 103, and determines the position of the joint T at that time.
From now on, the initial position of the joint T when performing the upper winding is determined. Note that the joint T
From the position to the position of the shipping roll S (more specifically, the length from the position of the adhesive tape a of the joint T to the position to be cut by the knife 106 disposed near the first drum 105). Is set in the control computer in advance as an initial set value because the paper movement path is fixed.

Then, the stopped shipping roll S resumes its rotation, and winds up the outer periphery thereof. The positioning of the joint T at this time is performed by measuring the amount of rotation of the first drum 105 by the tachometer in addition to the length L. That is, since the outer diameter of the first drum 105 is fixed, how long the paper is wound around the shipping roll S by the rotation amount of the first drum 105 (ie, the upper winding Is automatically determined. Therefore, for example, when it is desired to position the joint T at the outermost peripheral position of the shipping roll S as shown in FIG. 4 (a), as shown in FIG. What is necessary is to rotate one drum 105. Similarly, when it is desired to position the joint T on the first layer from the outermost periphery of the shipping roll S as shown in FIG. 4B, for example, as shown in FIG. What is necessary is just to rotate the drum 105. In this way, the position of the joint T is
It becomes possible to perform positioning control to a desired winding position.

As described above, the winder 60 of this embodiment is based on the length L of the paper from the joint position at the time of splicing to the position of the shipping roll S and the amount of upper winding. A configuration having an automatic joint position control mechanism for positioning the position of the joint T on the shipping roll S was adopted. According to this configuration, the initial position of the joint T,
Since the joint position of the upper winding of the shipping roll S can be easily obtained from the winding amount of the upper winding, it is possible to automatically position the joint position at an arbitrary position without requiring any manual operation.

Further, the winder 60 of this embodiment has a configuration in which the automatic joint position control mechanism obtains the winding amount of the upper winding based on the rotation amount of the first drum 105 disposed adjacent to the product winding roll S. Adopted. According to this configuration, since the length of the paper fed per unit rotation of the first drum 105 is determined, simply measuring the rotation amount of the first drum 105 can easily reduce the amount of upper winding. It is possible to ask. That is, the joint position on the shipping roll S can be easily obtained.

In the present embodiment, the winding amount of the upper winding is determined based on the rotation amount of the first drum 105. However, the present invention is not limited to this. You may adopt it.

Equipped with a joint position automatic control mechanism that positions the position of the joint in the product take-up roll based on the length of the paper from the joint position at the time of splicing to the product take-up roll position and the amount of top take-up. Configuration was adopted. According to this configuration, the joint position in the upper winding of the product winding roll can be easily obtained from the initial position of the joint and the winding amount of the upper winding. Automatic positioning can be performed.

Further, the winder according to claim 2 employs a structure in which the automatic joint position control mechanism obtains the winding amount of the upper winding from the rotation amount of the first drum disposed adjacent to the product winding roll. . According to this configuration, since the length of the paper fed per unit rotation amount of the first drum is fixed, the upper winding amount can be easily obtained only by measuring the rotation amount of the first drum. It becomes possible. That is, it is possible to easily find the joint position on the product take-up roll.

According to the third aspect of the invention, the same effect as that of the first aspect can be obtained.
