Abstract

PROBLEM TO BE SOLVED: To surely judge a state in which a cloth runs short by stopping a detecting means for detecting the end or the presence of the fed cloth and a motor for rotating a roller by a detection signal from the detecting means. SOLUTION: A noncontact type sensor 12 is arranged at the position of an automatic pasting machine main body which is nearer to a rolled cloth roll 10 which is a previous stage of a feed roller 2. After a state in which a cloth has run out or no cloth state being detected by the sensor 12, a motor for rotating the roller 2 by a detection signal is stopped. The stop is displayed by a display part installed in the upper part of the machine main body. In this way, a state in which the cloth is exhausted can be judged surely to conduct pasting work without wasting the pasted cloth.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic sizing machine. More specifically, the invention of the present application relates to a new automatic sizing machine that can easily determine the cutting of a cloth during the sizing operation, and also the sizing length and the remaining length at that time.

[0002]

2. Description of the Related Art Conventionally, there has been known an automatic sizing machine for sizing cloths such as wallpapers and sheets to be adhered to walls, ceilings and the like. This automatic sizing machine is typically
As shown in FIG. 1, the automatic sizing machine uses a raw material roll (1).
From the side where the cloth from 0) is inserted, a measuring roller (1), a sending roller (2), a high tension roller (3), a doctor roller (4), a gluing roller (5), and a gluing roller (6) , A press roller (7) and a flat roller (8).

The cloth to be glued is given an appropriate tension (tension) by a stay or a roller (11). That is, in FIG. 1, the cloth is used as a path (A) or (B) for a measuring roller (1). ) And the feed roller (2), and are fed into the body of the automatic gluing machine. The measuring roller (1) is supported at both ends and can rotate freely.
Further, since the measuring roller (1) is pressed against the surface of the cloth by a spring, it rotates in one direction in accordance with the feed of the cloth.

By setting the outer diameter of the measuring roller to a constant value, the amount of rotation of the roller is measured by a means such as detecting a slit plate obtained by equally dividing the circumference with a sensor. The distance traveled on the circumference, ie the length of the cloth to be glued in, can be obtained. The information on the cross length based on the scale is always displayed on the operation unit, and the operator can work while watching the situation.

When the required gluing length set in advance is reached, the machine automatically stops. The glue is stored in a glue box (9) provided at the lower part of the main body, and the glue in the glue box (9) is transferred to the glue roller (5) by the upper glue roller (6). By adjusting the distance between the doctor roller (4) and the gluing roller (5), the thickness of the glue adhering to the outer periphery of the gluing roller (5) is adjusted.

[0006] The glue layer whose thickness is controlled contacts the cloth, and the glue is transferred to the back surface of the cloth. Then, the transferred glue is leveled by the flat roller (8), and a cloth glued to a predetermined thickness is discharged from the front surface of the main body of the automatic gluing machine. In addition, the high tension roller (3) and the pressing roller (7) have a function of making the gluing thickness uniform and smoothly transporting the cloth.

The glued cloth is folded so that the glue surfaces are in contact with each other as shown in FIG. 1, for example. The automatic sizing machine having the above-described configuration greatly improves the workability by simplifying the sizing operation on the cloth. However, in the case of the conventional automatic sizing machine, there is a problem that the sizing machine continues to operate until the set value is obtained even when the remaining amount of the cloth is smaller than the predetermined length.

Further, the cloth to be glued is not necessarily a continuous cloth even if it is a single roll of raw material. In many cases, the cloth is cut off in the middle and wound up. (For example, a 35m cross may be wound into a 35m by winding a 20m and 15m cross.) Therefore, even if the raw material is not at the end, it is cut off midway and the cross disappears. As a result, the gluing machine continues to operate until the set value is reached.

[0009] This is due to the fact that the required gluing length is set and input in a state where it does not match the remaining amount of cloth in the gluing by the automatic gluing machine. And
Conventional automatic gluing machines do not employ a mechanism for automatically stopping the automatic gluing machine in a cross-cut state where the cloth is lost or the cloth is cut halfway.

For this reason, as described above, even when the cloth remaining amount is smaller than the set predetermined length or when the cloth is cut off halfway, the gluing machine continues to operate until the set value is reached. Was inevitable. In fact, if the cloth disappears during the gluing operation, the ends of the cloth are the measuring roller (1) and the feed roller (2).
Even when the measuring roller (1) passes through the gap, since the measuring roller (1) is pressed against the feed roller (2) by the spring, the measuring roller (1) rotates even though there is no cloth.

For this reason, the display on the operation unit continues counting as if there is a cross. The end of the cloth is separated from the feed roller (2),
Since the glue has viscosity, the cloth is conveyed as the gluing roller (5) rotates. When the end of the cloth has passed through the gluing roller (5), the cloth drops due to its own weight. The machine continues to run idle even when the cross is gone and stops when the operator notices or stops or the count reaches the set value.

[0012] Usually, as the skill of gluing work becomes more proficient, the fact that the cloth has disappeared can be generally recognized by sounds and signs such as the rotation of the rollers and the rotation of the cloth material. Since the stop switch is pushed to stop the operation, the above-mentioned situation is rare. However, in the case of an operator who is not yet used to the gluing machine, the worker will stop after the cloth comes out.

The glued cloth is folded so that the surfaces to which the glue is attached are aligned with each other as shown in FIG. 1, so that the length of the cloth once passed through the gluing machine is reduced. It is practically impossible to measure accurately with a measure or the like because it takes a lot of time. As a result, the length of the cloth finally glued remains unclear.

In a normal gluing operation, first, a room is measured, the required length and the number of sheets are written on a memo sheet or the like. However, if the length of the glued cloth is not accurately known, the place to be stuck is not known, and the cloth cannot be used without a wall which is apparently sufficient.

Therefore, under the present circumstances, when the remaining cloth becomes small, the worker estimates whether or not the next glued length is sufficient from the thickness and the winding thickness of the cloth cloth, and judges that the cloth is not enough. If you can't use it anywhere while looking at the note paper, you can replace it with a new one. When it is quite likely, start gluing, press the stop button once when the cloth comes off from the raw core bar, stop the gluing machine, while comparing the remaining length and the counter display, inching to the required length It will be glued and cut.

This is a very troublesome work, and the smoothing of the gluing work is lacking. If the judgment is incorrect, the useless cloth is likely to be glued. Also, if you do not notice that you are careless and there is little residue of the cloth, it will be as described above. Therefore, the invention of this application is to solve the conventional problems as described above, to accurately determine the state where the cross is lost, and to perform the gluing operation smoothly and without wasting the glued cloth. The purpose is to provide a new automatic sizing machine that can do.

Hereinafter, examples will be shown, and embodiments of the invention of this application will be described in more detail.

[0023]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 2 of the accompanying drawings shows an example of the present invention in correspondence with FIG. 1, and shows an automatic sizing process which is closer to the former stage of the feed roller (2), that is, closer to the material roll (10). A non-contact type sensor (12) is disposed at a part of the machine body as a means for detecting the end of the cloth or the presence or absence of the cloth.
As shown in FIG. 3, the sensor (12) is mounted on a cover body (13) of the automatic gluing machine body which can be opened and closed.

FIG. 4 more specifically shows an example in which a reflection type beam sensor (121) is used as the sensor (12). Detect. Detection is possible without damaging the cloth at all. The reflection type beam sensor (121) may detect from the back side of the cloth as shown in FIG.
This method is characterized in that it is hardly affected by the type of cloth.

In both cases of FIGS. 4 and 5, the sensor is located at a position closer to the raw roll (10) than to the feed roller (2). In addition to the non-contact type sensor, in the present invention, the end of the cloth or the presence or absence of the cloth may be detected using a contact type sensor. FIG.
Shows an example of this, in which, for example, a micro switch (122) is attached to the stay of the main body of the automatic gluing machine in front of the feed roller (2), and the presence or absence of a cloth is determined by the micro switch (122). Is performed by turning on / off the switch. This method enables reliable detection.

In detecting the end or presence or absence of the cloth,
In the above example, the sensor is disposed on the main body. However, the present invention is not limited to this, and may be a leg portion of an automatic gluing machine or a slitter portion as long as it is a stage preceding the feed roller (2). . For example, as illustrated in FIGS. 1 and 2, in an automatic sizing machine, a stay or a roller (11) is disposed on a leg portion thereof, and a moderate tension (approximately) is applied to a cloth sent out from a raw material roll (10). Tension) to prevent the cloth from bending or wrinkling. Because of this, this stay or roller (11)
A detection means for detecting the end of the cloth or the presence / absence of the cloth may be provided at an appropriate position such as a leg on which is disposed. It may be a non-contact sensor or a contact sensor.

FIG. 7 shows an example of the detecting means in such a leg. That is, an electrically conductive tension stay (111) is disposed horizontally with respect to the leg (14) also shown in FIGS. 1 and 2, so that an appropriate tension is applied to the cloth, and the conductive tension stay is provided. With respect to (111), the lever (1) is supported by the fulcrum (15).
An electrically conductive stay or roller (17) which is swingable through 6) and can be abutted is disposed.

A conductive tension stay (111);
The electrical continuity is turned ON / OFF depending on whether or not there is a cross between the conductive stay and the roller (17), whereby the end or the presence or absence of the cross is detected. Of course, the ON / OFF of the conduction in this case is not based on the method using the lever (16) as shown in FIG.
As shown in FIG. 8, a conductive stay or roller (17)
Other suitable means are considered, such as making it freely slidable by grooves or notches in the guide pieces (18) arranged at both ends thereof, and making it slidable on the conductive tension stay (111). .

Of course, as a sensor as a means for detection, various sensors such as a sensor utilizing light such as the above-described reflected beam sensor, an ultrasonic sensor, a capacitance type sensor, a magnetic sensor, a piezoelectric sensor, etc. Things can be adopted as appropriate. Further, the detecting means such as the sensor may be provided at a plurality of positions in the automatic gluing machine.

This means that the detection of the end of the cloth and the detection of the presence or absence of the cloth may be separated into functions. Regardless of the single or multiple installations, the detection of the presence / absence of a cloth is only performed when there is a cloth, and the glued length is added to the numerical value of the measuring roller (1). It can also be configured as a mechanism for counting the length and displaying this. As a result, the actual total gluing length is indicated even in a plurality of gluing operations.

For detecting the end of the cloth or the presence or absence of the cloth, the application of tension (tension) to the cloth by a stay or a roller (11) such as a tension stay (111) can be used as it is. That is, the presence or absence of this tension is detected as a change in the load on the motor device that rotates the roller of the automatic gluing machine. When a substantially constant tension is always applied to the cloth by the stay or the roller (11), the load applied to the motor device is substantially constant, but the load is reduced when the cloth disappears. This change is read from the change in the current value of the motor device, and the absence of the cross, that is, the state of the cross break or the presence or absence of the cross is detected.

This method can be carried out without attaching a sensor or the like to the gluing machine main body as in the above example. As the electric measurement system of the motor device, the cut of the cross or the presence or absence of the cross is detected by the change of the current value. In any of the above cases, the end of the cloth whose cross is detected or the presence or absence of the cross is detected in front of the measuring roller (1) and the feed roller (2) as in the specific example described above. Will be suspended.

In the present invention which employs various detection means as described above as means for such a stop, for example, after detecting a cut or no cross state, the automatic gluing is carried out by the detection signal. A drive control mechanism for stopping a motor device for rotating rollers of the machine body is provided. In response to the detection signal, the drive of the motor device is stopped by this drive control circuit mechanism.

This stop is performed on a display unit provided at the upper part of the main body of the automatic gluing machine, detachably attached to the main body, or provided on a box body connected to the main body by a cable or the like.
For example, it is displayed by a display means such as lighting of a warning indicator as shown in FIG. Then, the gluing length of the cloth until the cloth is stopped is also displayed on the display unit.

The display section shows whether the cloth is broken or not,
Alternatively, the stop of the motor device can be displayed by various methods. As a result, a situation in which the automatic sizing machine runs idle due to a broken cloth or the like does not occur. All the pasted cloths are discharged from the pasting machine and are put in an overlapped state, and there is no inconvenience that the length of the cloth is no longer determined by the inspection by the idle rotation of the inspection roller. No waste of cloth. Gluing is performed until the automatic sizing machine stops, and it is easy to determine the usable cross length in the stopped and cross-cut state, and to use it for construction.

In the stopped state, the remaining length until the end of the cloth actually passes through the measuring roller (1) remains. In the examples of FIGS. 2 to 6 in which the sensor is installed on the main body of the automatic gluing machine, the remaining length is relatively short, but as in the examples of FIGS. Is longer in the example of detecting the cross end. However, in any case, the remaining length is substantially constant according to the position of the adopted end detection means.

Since this constant is known in advance,
From the pasted cloth length and the remaining length, the finally usable cloth pasting length can be easily determined. For example, in the example shown in FIGS. 7 and 8 having a relatively long remaining length, the remaining length (L ₁ ) expected to substantially correspond to the length from the measuring roller (1) to the tension stay (111). However, in the relationship between the glue cloth length (L ₂ ) counted so far and the glue setting length (L) required for cloth bonding, when L−L ₂ <L ₁ , , after the stop, to a length of L-L _2, or even to continue the glue without stopping. On the other hand, in the case of L-L _2> L ₁ is, because there is no sense to continue the glue, to completely stop with automatic glue machine.

By doing so, the worker can work without worrying about the remaining amount of cloth. By indicating the set length on the display unit shown in FIG. 9 in advance, the above determination can be made extremely easily immediately. In addition,
The gluing machine stopped by detecting the end of the cloth or the presence or absence of the cloth enables continuous gluing or discharge of the remaining cloth by inching, an interrupt switch, or the like.

To this end, the drive control mechanism of the motor device detects the end (presence / absence) of the cloth with a sensor or the like, and then detects the expected cloth remaining length, the gluing set length (L), comparison with ever counted the length of the glue application cross (L ₂₎ is calculated from the length (L-L _2), a function of determining whether to stop at that point or continues the glue You can have.

On the other hand, the automatic sizing machine may be automatically stopped when the remaining length of the cloth becomes a predetermined length without using the cloth end detecting means as in the above example. That is, when the cloth material roll (10) is set, its initial length (L ₀ ) is input in advance, and the length (L ₂ ) that has been glued together with the automatic gluing is subtracted to obtain the remaining length (L ₀ ). L ₁ ), that is, L ₀ −L ₂
However, a warning or a message is issued when L ₁ = L ₀ −L ₂ <L, and the automatic gluing machine is stopped in comparison with the gluing set length (L) necessary for the cloth pasting operation. Good.

This is made possible by the arrangement of a drive control mechanism for stopping the motor device for rotating the roller by calculation and instruction based on a signal from the measuring roller (1). In the above case, the above-mentioned subtraction may be such that the length is subtracted from the pasting degree for each of a plurality of pastings, or the pasting length of each time is added and A method of calculating the remaining length by subtracting from the initial length every time or as needed may be adopted. Of course, both of these methods may be selected at any time.

The method of substantially detecting the cross end by such a method may be appropriately combined with and used in combination with the method of detecting the cross end by the sensor or the like.
When a sensor or the like for detecting the presence or absence of a cloth is provided as this combination, the detection of the presence or absence of the cloth is performed by adding the glued length from the numerical value of the measuring roller (1) only when there is a cloth. It is also possible to configure a mechanism for counting the total length of only the cloth glued to the surface and displaying the total length.

Of course, the invention of this application is not limited by the above examples. Various aspects are possible in its details. The drive control mechanism of the motor device is appropriately configured as an electric circuit, and a detection unit using a sensor is variously configured as a common technical knowledge, without needing to be described in detail again.

[0044]

As described above in detail, according to the invention of this application, it is possible to perform the sizing operation without worrying about the remaining length of the cloth, and the cloth is sufficient for the set length before the cloth runs out. If not, the operation is automatically stopped, so that a smooth sizing operation can be performed without giving out a useless cloth or a sizing cloth of unknown length.
