Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a process for pasting the trailing end of a rolled paper of a predetermined length, and also for pasting the trailing end of the rolling paper, in which markings are made on the pasted portions of the rolling paper. This invention relates to a marking device.

<Prior Art> As is well known, wrapping paper such as toilet paper is glued at the tail end at a position slightly away from the end so that it can be easily peeled off during use. Conventionally, when pasting such wrapping paper, a predetermined length of paper is wound around a core material, and the pasting process is performed almost at the same time as the paper is cut.

<Problems to be Solved by the Invention> However, in the above processing method, the adhesive is applied to the inside of the paper, so the adhesive strength is too strong.
The third and third sheets of paper are torn, difficult to use, and wasted. In addition, it is difficult to tell where the glue is attached to the wrapping paper, so the wrapping paper may be torn in the middle and used without knowing where it should be peeled off and used, resulting in waste. For this reason, after winding and cutting a predetermined length of paper, the trailing end is pasted with an appropriate adhesive force, and the trailing end of the paper is
In other words, it is desired to develop a technique that clearly indicates the position at which to start peeling and use.

However, if the adhesive is simply applied from the outside of the trailing portion, the adhesive force may be too strong or too weak each time the adhesive is applied, making it impossible to obtain a stable adhesive force. Furthermore, since the appearance of the adhered area is the same as the surrounding area, it is difficult to identify the peeled area.

<Means for Solving the Problems> The present invention has been proposed in view of the above, and includes an endless transfer member that is movable by a drive source and is placed below a pair of rollers that support the paper rolls, and extends the length of the rollers. In addition, the transfer member is provided with a pressing member that faces within the interval between the rollers and presses the rear end of the paper on the roller, and the paper on the roller is transferred in the length direction of the roller. A paper roll detector is provided on the transfer path formed on the extension line of the roller along which the paper roll removed from the roller is moved by the operation of the transport mechanism, and an adhesive is applied from the outside to the trailing part of the paper roll. Above the transfer path and behind the nozzle, a marking roller having a protrusion on the outer circumferential surface that can be pressed along the length direction of the upper edge of the paper wrapping paper to be transferred is placed. The adhesive attaching mechanism is configured to adhere the trailing portion of the wrapping paper and provide a stamp based on the detection of the end of the wrapping paper by the wrapping paper detector.

<Function> According to the above-described configuration, the present invention applies an adhesive from the outside to the trailing end of a paper wrapping paper cut into a predetermined length, and presses the trailing end portion with a stamping roller having a protrusion to form the trailing end. is attached to the second sheet of paper with appropriate adhesion force, and the attached part is engraved to indicate the peeling position, and the trademark, manufacturer's name, pattern, etc. are displayed to increase the added value of the product. be able to.

<Example> The present invention will be described below based on an example in which the present invention is applied to a toilet paper winding device.

The adhesive stamping device 1 according to the present invention includes an adhesive adhering and stamping mechanism 2 that applies adhesive to the trailing end of the wrapping paper R, pressurizes it, and stamps it, and a pair of rollers 3, 3 that support the wrapping paper R. It has a transfer mechanism 4 that transfers the paper wrapper R on the rollers 3, 3. Furthermore, as is well known, toilet paper comes in rolls with lengths of 45 m, 60 m, and other lengths, each with a different diameter. A rear stop position regulating mechanism 5 is provided so as to stop at the upper end of the rear end.

According to the embodiment shown in FIG. 1, the adhesive adhesion marking mechanism 2 has a nozzle 7 directed downward above the entrance 6' of the transfer path 6 formed adjacent to the extension line of the rollers 3, 3. A solenoid valve 9 is installed between the nozzle 7 and the tank 8.
A marking roller 11 rotatably attached to the tip of an arm rod 10 that can swing around its base end is arranged behind the nozzle 7. Stamp roller 1
Reference numeral 1 has a disc shape made of metal, hard plastic, etc., and has a protrusion 12 for stamping characters, patterns, etc. on the outer peripheral surface. This stamping roller 1
2 applies pressure continuously from above to a portion slightly away from the end of the trailing portion of the wrapping paper using its own weight or a biasing force such as a spring, and with a constant biasing force.

The rollers 3, 3 are arranged at appropriate intervals to support the paper roll R, and an endless chain is connected to a sprocket 14 fixed to the end of the shaft 13 of each roller 3 and a sprocket 16 of a first drive source 15 consisting of a motor or a speed reducer. 17 is spanned over the bridge.

The transfer mechanism 4 includes an endless transfer member 18 such as a chain or a belt below the rollers 3 and 3.
The drive chain 24 spans the sprockets 19, 19 along the length direction, and runs between the drive sprocket 21 provided on the shaft 20 of one sprocket 19 and the sprocket 23 of the second drive source 22, forming a substantially L-shape. Pressing members 25, 25 of the shape are fixed to the transfer member 18, and the pressing members 25, 25 are moved between the rollers 3, 3 with their tip portions protruding upward from the gap between the rollers 3, 3. be. Therefore, when the second drive source 22 is started after the trailing end stops at the upper end of the paper roll R, the pressing member 25, which has been waiting at one end within the gap between the rollers 3, 3, moves the paper roll R by the movement of the transfer member 18. Press the roller 3,
It can be delivered to a transfer path 6 adjacent to the end of 3.

At the entrance 6' of the transfer path 6 through which the paper roll R passes, a paper roll detector 26 for detecting the paper roll R that has entered is arranged. The wrapping paper detector 26 includes a light emitter and a light receiver, and detects the presence or absence of the wrapping paper R based on the amount of light that hits the wrapping paper R and is reflected. Therefore, when the wrapping paper R that has come off from the rollers 3 and 3 due to the pressure of the pressing member 25 enters the transfer path 6, the wrapping paper detector 26 detects the front end of the wrapping paper R, and the adhesive adhesion stamping mechanism 2
start.

That is, when the front end of the wrapping paper R that has come off the rollers 3, 3 passes through the entrance 6' of the transfer path 6, the wrapping paper detector 26 detects the start of passage of this wrapping paper R, and the electromagnetic valve 9 is activated.
is opened, and a small amount of the adhesive in the tank 8 is sprayed from the nozzle 7 to adhere to the rear part.

As the adhesive, an adhesive such as water or water paste can be used.

As described above, the wrapping paper R with the adhesive attached to the trailing part is guided by the guide plate 27 provided along the transfer path 6 and moves in the length direction, and the trailing part immediately after the adhesive is attached is engraved. It passes under the roller 11. Then, a portion of the trailing portion of the wrapping paper R slightly away from the end is continuously pressed from above with a constant urging force. Therefore, the part pressed by the stamping roller 11 is thinly pasted with the adhesive force as designed and has a width equal to the thickness of the stamping roller 11, and is also attached to the outer peripheral surface of the stamping roller 11. A stamp is provided by a raised protrusion 12.

When the rear end of the wrapping paper R stamped in this way passes in front of the wrapping paper detector 26, the wrapping paper detector 26 detects the completion of passage of the wrapping paper R and closes the solenoid valve 9, causing the adhesive to flow out. stop. Therefore, it is possible to eliminate waste of the adhesive and prevent the adhesive from adhering to the end face of the wrapping paper R.

In the above embodiment, the adhesive is directly attached to the trailing portion of the wrapping paper R from the nozzle 7 directed toward the upper end.
The nozzle 7 or the adhesive supplying material such as felt is provided to face or come into contact with the marking roller 11,
It may also be indirectly attached to the trailing portion by pressing with the marking roller 11. In addition, the transfer member 18
may have a length that allows the wrapping paper R to be transferred from above the rollers 3, 3 into the transfer path 6, for example, almost the same length as the rollers 3, 3. In this case, a belt conveyor may be provided in the transfer path 6, and the paper wrapper in the transfer path 6 that has undergone the pasting and marking process may be transported by the belt conveyor.

On the other hand, a trailing stop position regulating mechanism 5 that causes the tail of cut paper to stop at the upper end of the paper roll R regardless of the diameter of the paper roll R is connected to a winding device ( A tail detector 29 is provided facing downward above a table 28 (not shown) arranged at a rear stage, and a detection rod 30 is provided facing above the pair of rollers 3, 3 provided along the sloping lower end of the table 28. It is composed of etc.

The table 28 is sufficiently wider than the diameter of the wrapping paper R, and its upper surface is slightly inclined downward toward the rollers 3, 3. Therefore, when the paper roll R sent out from the winding device is transferred to the table 28, it rolls due to the inclination and can be placed on the rollers 3, 3.
Note that the wrapping paper R is placed on the rollers 3 while rotating in the direction of unraveling the paper. Therefore, the paper at the end of the wrapping paper R extends on the table 28 in an unraveled state. Therefore, the first driving source 1
5 is activated, the rollers 3, 3 rotate, the wrapping paper R rotates, and the paper extended on the table 28 can be wound up.

The detection rod 30 that detects the diameter of the rotating paper roll R as described above is a bar having an appropriate length, and its base end is fixed to a support shaft 31 rotatably supported above the table 28. However, the detection section 30' at the lower end, which swings about the support shaft 31, faces above the rollers 3, 3. Therefore, the wrapping paper R rolled on the table 28 is placed on the rollers 3, 3, and the detection unit 3
0', the detection rod 30 swings in a direction perpendicular to the length direction of the paper wrapper R around the support shaft 31 in accordance with the diameter of the paper wrapper R. Then, the detection rod 30 transmits this swinging motion to the rear detection base 29 via the interlocking means.

The tail detector 29 includes a light emitter and a light receiver,
Light is irradiated from the light emitter onto the top surface of the table 28, and the reflected light is received by the receiver, and the presence or absence of paper is detected based on the amount of received light, that is, the difference in reflectance between the white paper and the dark colored table 28. It is fixed to a rotating rod 32 rotatably supported above the table 28, and is focused on the upper surface of the table 28. The trailing detector 29 is electrically connected to the first drive source 15 via an electrical control device (not shown) having timer means.

An embodiment of the interlocking means that rotates the rear detector 29 by the rotation of the detection rod 30 includes the tip of the first arm 33 fixed to the support shaft 31 and the tip of the second arm 34 fixed to the rotation rod 32. are connected by a connecting rod 35, and when the detection rod 30 rotates, the rear detector 29 rotates in the same direction. and the first arm 33
By appropriately setting the length of the second arm 34 and the length of the second arm 34, the rear detector 2 can be
9 rotation angles can be adjusted.

As shown in Fig. 2, the large diameter paper roll R is placed on the table 2.
When the detection rod 30 rolls on the rollers 3 and 3, the detection rod 30 rotates greatly as shown by the solid line in FIG. 29 rotates clockwise as shown by the solid line in FIG. 2, and the rear detection position moves to A. The paper on the table 28 is gradually wound up by the rotation of the rollers 3, 3, and when the tail passes through A, the tail detector 29 detects the passage of the tail, and the electric control device transmits a signal. When the electric control device receives the signal, it starts the timer means and stops the first drive source 15 after a certain period of time has elapsed. The fixed time set in the timer means is the time from when the trailing detector 29 detects the trailing edge of the paper until the trailing edge reaches a predetermined position at the upper end of the paper roll R, and is determined by the rotational speed of the rollers 3, 3. determined. Therefore, when a certain period of time has elapsed since the trailing detector 29 detected the trailing edge, and the electric control device stops the operation of the first drive source 15 and stops the rotation of the rollers 3, 3, the trailing edge is detected by the rolling paper R. Stops at a predetermined position at the top of the

On the other hand, when the small-diameter paper roll R' rolls on the table 28 and is placed on the rollers 3, 3, the detection rod 30
rotates slightly as shown by the chain line in Figure 2, and the first,
The tail detector 29 via the second arms 33, 34, etc.
rotates slightly as shown by the chain line in FIG. 2, and moves the detection position to B, which is farther than A. Then, the paper on the table 28 is gradually wound up by the rotation of the rollers 3, 3, and when the trailing edge passes through B, the trailing detector 29 detects the progress of the trailing edge in the same manner as described above, and the electric control device is activated for a certain period of time. After the elapsed time, the first driving source 15
, and the rotation of rollers 3 and 3 is stopped. In this case, the trailing detector 29 detects the trailing position of the paper at different positions for the large-diameter wrapping paper R and the small-diameter wrapping paper R', so
The length of the paper remaining on the table 28 varies.
However, since the outer circumference of the wrapping paper R' is shorter than the outer circumference of the wrapping paper R, when the rollers 3, 3 rotate for a certain period of time after detecting the trailing edge of the paper, the trailing edge rises to a predetermined position at the upper end of the wrapping paper R' and then stops. It turns out. In other words, if rollers 3 and 3 are rotating at the same speed,
The upper end position of the wrapping paper R when the trailing tail of the paper is wound up from the position A where the trailing tail of the paper is detected.
The length up to A' is equal to the length of the paper roll R' from the position B where the tail of the paper is detected to the upper end position B' of the paper roll R' when this tail is wound up.

Note that the trailing detection positions A and B are the diameters of the rolls R and R',
This is calculated from the time set in the timer means and the rotational speed of the rollers 3, 3. The length of the detection rod 30 and the lengths of the first and second arms 33 and 34 are adjusted so that the trailing detector 29 aims at the detection positions A and B according to the diameters of the rolls R and R' according to this calculation. Set the

When the trailing ends of the wrapping papers R, R' stop at the upper ends as described above, the sticking and stamping device 1 according to the present invention operates to stamp the trailing ends of the wrapping papers R while sticking them.

Then, the pressing member 25 that presses the paper roll R to the exit 6'' of the transfer path 6 and sends it out to the next process is reversed at the sprocket 19, contacts the stop switch 36, and stops the second drive source 22. The transport member 18 also stops moving.At this time, the other pressing member 25 stops at the end of the gap between the rollers 3, 3 and waits to be able to press the next paper roll R.

Incidentally, in the above embodiment, the first drive source 15 rotates the paper roll R on the table 28 and detects the tail detector 29.
It is desirable that the second drive source 22 starts driving when the first drive source 15 is detected, and that the second drive source 22 starts driving at the same time as the first drive source 15 stops.

<Effects of the Invention> As explained above, according to the present invention, an adhesive is applied from the outside to the trailing portion of the wrapping paper that has been wound up to a predetermined length and cut, and the trailing portion is applied with a constant force using a stamping roller. A trademark, manufacturer's name, pattern, etc. can be engraved while applying pressure. Therefore, when pasting the tail end of the wrapping paper, not only can an appropriate adhesive force be obtained at all times, but also the added value of the product can be increased, and processing can be performed reliably at high speed. According to the present invention, since the attachment position can be easily determined, it is possible to provide toilet paper or the like that is easy to use because the use start position can be seen at a glance.
