Description

  The present invention relates to a wallpaper pasting machine for continuously applying glue to the back surface of a sheet-like wall covering material stuck to an indoor wall surface or the like.

  At present, wall coverings in interior construction of buildings are applied to indoor wall surfaces by continuously applying glue to sheet-like wall coverings (hereinafter also referred to as crosses) using a dedicated wallpaper pasting machine. It is common to do this.

  As a general wallpaper pasting machine, a cloth is drawn from the rear surface to the front surface between the upper structure and the lower structure by a plurality of rollers arranged on the upper structure and the lower structure connected to each other, and the cloth is crossed by various rollers. Has been proposed that continuously transfers the glue in the glue basket in the lower structure to the back surface of the cloth while moving it along a predetermined path (see, for example, Patent Document 1). The machine is already on the market.

  As a more general configuration, a lower structure and an upper structure having glue ridges are arranged between a base for suspending a cloth wound in a roll shape and a cloth receiver for receiving the cloth after pasting. The main body of the gluing machine consisting of the upper structure and lower structure where the rollers are placed is placed on the support leg, and the cloth sandwiched between the upper and lower structures is conveyed by the roller while Glue is glued up with a roller, and glue is transferred onto the back of the cloth.

  Specifically, the cloth fed from the roll roll is placed on the lower structure with the tip portion hanging forward of the main body, the upper structure is closed, and the cloth is sandwiched between predetermined rollers of the lower structure and the upper structure. Then, transfer the paste onto the back of the cloth.

  Such a wallpaper pasting machine has a manual type and an automatic type. That is, in the manual type device, the operator pulls forward with the cross tip, so that a part of the roller sandwiching the cross is rotated following and the other roller is rotated in conjunction with the gear to rotate the cross. The glue is transferred from the roller to the back on the top of the roller where the glue in the glue basket is pulled up by its rotation while being conveyed from the back to the front of the gluing machine body. It will be sent out. Further, in the automatic apparatus, by rotating the shaft of a predetermined roller connected to a drive source such as an electric motor, the other rollers also rotate in conjunction with each other through a gear.

  The specific behavior of such a wallpaper pasting machine will be described using an automatic wallpaper pasting machine as an example. FIG. 6 is an explanatory diagram showing the internal configuration of a conventional automatic wallpaper pasting machine. As shown in the drawing, a plurality of rollers are arranged in an upper structure 105 and a lower structure 104 constituting the gluing machine main body 101, and a glue basket 106 containing glue is contained in the lower structure 104. Is provided.

  In the upper structure 105, an upper pinch roller 151 that constitutes a pinch roller for taking the cloth into the gluing machine main body from the rear side, and a feeding tension in the front direction of the gluing machine main body are applied to the cross C. Drive roller 153 and a pressing roller 152 that presses the cloth from above and rotates following the movement of the cloth between the upper pinch roller 151 and the drive roller 153 are arranged in parallel with each other at a predetermined interval. These are pivotally supported on the side plates of the upper structure 105.

  Further, in the lower structure 104, a lower pinch roller 142 that constitutes a pinch roller paired with the upper pinch roller 151, a gluing roller 141 that applies a glue solution to the back of the cloth, and a gluing amount in contact with the gluing roller The lower structure 104 is arranged so that a doctor roller 144 for adjusting the pressure and a leveling roller 143 that applies an appropriate tension to the cloth together with the drive roller 153 and feeds it in the front direction are arranged in parallel with each other at a predetermined interval. It is pivotally supported on the side plate. The glue raising roller 161 is pivotally supported on both side surfaces of the glue basket 106 and transfers the glue solution in the glue basket 106 to the glue roller 141.

  Normally, all of the plurality of rollers arranged in the lower structure 104 are linked with each other through a gear. On the other hand, in the arrangement in the upper structure 105, the drive roller 153 is interlocked with the gear system of the lower structure 104 via a gear, and the upper pinch roller 151 and the pressing roller 152 are rotationally driven by other rollers. In this way, it is brought into contact with the cloth being conveyed from the rear to the front and rotates following the surface friction.

  In the gluing operation using the wallpaper gluing machine having such a configuration, first, the upper structure 105 is opened with respect to the lower structure 104, and the original cloth is supported by the back of the gluing machine body 101. Pull out the tip of the cloth C from R, pass through the slitter 120 attached to the back of the gluing machine main body through two tension bars, and then lower the cross so that the tip hangs down to the whole body side. The pinch roller 142, the gluing roller 141, It is placed on the leveling roller 143, the upper structure 105 is closed, and the cross is sandwiched.

  In the state where the cloth is set in this way, in the case of the automatic wallpaper pasting machine, the driving is started by the inching amount by the inching command from the drive control device (not shown). When the rollers connected by gears by this initial driving start to rotate at a predetermined peripheral speed ratio, the glue raising roller 161 transfers the glue to the glue roller 141 while placing glue in the glue basket. The glue transferred to the surface of the gluing roller 141 is adjusted to a predetermined amount by the doctor roller 144 and then transferred and applied to the back surface of the cloth sent to the top of the gluing roller 141 via the pressing roller 152.

  The glued cloth is then pulled while being tensioned by the drive roller 153 and the leveling roller 143, and sent to the front surface of the main body while leveling the glue surface by the leveling roller 143. When pasting is performed on the back surface of the cloth corresponding to the inching amount, the driving of the apparatus is temporarily stopped, and an unnecessary cloth portion that is not pasted at the tip is cut with a cutter to finish the preparation for pasting.

After the pasting preparation is completed, the actual condition settings such as the cross length are input to the drive control device, and when the drive of the device is started by the motor according to the operation command from the drive control device, the entire back surface is glued. When the cross is fed out from the front of the main body and reaches a desired length, the motor drive is stopped. The cloth with the desired length was cut by a cutter along a cutter guide disposed in the longitudinal direction on the front surface of the gluing machine at a predetermined length by the operator, folded, and placed on the front side of the gluing machine Deposited on the tray T.
Japanese Utility Model Publication No. 6-81800

  In such a wallpaper pasting machine, pasting is performed while unwinding the roll wound in a roll shape, but there is no detection means for detecting the passage of the cross terminal when the remaining amount of the cross decreases. If it is a manual type wallpaper pasting machine, it is immediately known that the end of the cloth wound in a roll shape has passed through the pasting machine because the operator pulls out the cloth.

  However, when an automatic wallpaper pasting machine is used, a pinch pressure is always generated between the upper pinch roller 151 and the lower pinch roller 142 used as a measuring roller. Since the sticking length continues to be counted, the operator does not know the pasting length of the last cloth, and it is necessary to re-measure the length after pasting, which significantly impedes the work efficiency.

  The present invention detects automatic passage of a cloth wound in a roll that is glued while being unwound, and can automatically stop driving the glued roll when the terminal is detected. The aim is to get a chance.

The automatic wallpaper pasting machine according to the invention described in claim 1 is a glue paste in the pasting machine main body while feeding the sheet-like wall covering material drawn from the rear part of the pasting machine main body forward by a plurality of rollers. In an automatic wallpaper pasting machine that applies paste liquid continuously by transferring the paste liquid contained in the back surface of the wall covering material with a glue roller,
Cross break detection means for detecting the passage of the end of the sheet-like wall covering immediately before the glue roller and stopping the drive of the glue roller is provided.

Preferably, the cross break detecting means is
A rotation detecting means for detecting a rotation state of a pressing roller that is pressed from above to rotate the gluing roller that is rotationally driven by a driving mechanism and that rotates according to the movement of the wall covering;
Control means for recognizing the presence or absence of rotation of the pressure roller during rotation of the gluing roller and outputting a cross break signal to stop driving of the gluing roller when there is no rotation of the pressure roller. Is.

The automatic wallpaper pasting machine according to the invention described in claim 2 is characterized in that the cross break detecting means according to claim 1 comprises:
As the rotation detecting means, one or more magnet pieces mounted around one axial center of the pressing roller;
A non-contact type switch that detects the proximity and separation of the magnet pieces as the pressing roller rotates;
A body side coil connected to the switch;
The controller side coil installed in the controller opposite to the main body side coil,
The control means induces the main body side coil during the transition from the energized state to the non-energized state by the switch while energizing a pulse current of a predetermined frequency to the controller side coil during the rotational driving of the gluing roller. When the change due to the current is recognized and the pressing roller does not rotate, a cross break signal is output to stop driving the gluing roller.

In an automatic wallpaper pasting machine according to the invention described in claim 3 , the non-contact switch according to claim 2 is configured to magnetize two magnetic lead thin plates with a minute gap as a contact, A reed switch that switches according to the movement of one or more magnet pieces mounted around one axis of the pressing roller is provided.

  The present invention detects the passage of the end of a cross wound in a roll shape to be glued while being unwound, and can quickly stop the glue roll from being driven when the end is detected. There is no need to re-measure the pasting length, and an automatic wallpaper pasting machine that does not significantly impair the pasting work efficiency can be obtained.

  In the present invention, there is provided a cloth breakage detecting means for detecting the end of the sheet-like wall covering material and stopping the driving of the gluing roller. When the terminal is detected, the drive of the glue roller can be stopped immediately, and no glue liquid will adhere to the surface of the cloth even when a new cloth is attached. It is.

  The cross break detection means of the present invention includes a means for detecting the end of the cloth in a non-contact manner using an optical sensor or the like, or a roller other than the existing rollers in the automatic wallpaper pasting machine is brought into contact with the cloth and the cross is detected by the rotation. Means for detecting the terminal of the terminal can be considered. However, in the case of using an optical sensor, if dirt is attached to the light receiving portion or the like, there is a risk of malfunction or inoperability, which is not feasible.

  Further, in the contact type or non-contact type detection means, since a new roller is arranged to bring a roller other than the existing roller into contact with the cloth, it is troublesome to remove and attach it. Specifically, the wallpaper pasting machine needs to be cleaned at the end of the pasting operation, not only removing the controller and washing with water, but also removing the pasting roller and other rollers from the pasting machine body or leaving them attached Wash with water. At that time, optical sensors that require electrical processing and counters provided on the rollers prevent short circuit due to cleaning water during cleaning. Remove non-contact optical sensors and rollers that contact the cloth during cleaning. It is necessary to install after washing.

  Therefore, in the present invention, the cross break detection means rotates from the top to press the wall covering against the surface of the gluing roller that is rotationally driven by the drive mechanism and rotates according to the movement of the wall covering. A rotation detecting means for detecting the presence of rotation, and a control means for recognizing the presence or absence of rotation of the pressure roller during rotation of the gluing roller and outputting a cross break signal and stopping the gluing roller when there is no rotation of the pressure roller Including. As a result, since the pressing roller, which is an existing roller, is used, it is possible to detect the passage of the cloth end just before the gluing roller, so there is no waste in the cloth and it is ensured that the end of the cross exceeds the gluing roller. Can be stopped.

  Further, in the present invention, the cross break detecting means includes one or more magnet pieces mounted around one shaft center of the pressing roller as the rotation detecting means, and the magnet pieces approaching / separating as the pressing roller rotates. A non-contact-type switch for detecting the main body, a main body side coil connected to the switch, and a controller side coil installed in the controller opposite to the main body side coil, and the control means rotationally drives the glue roller While the controller side coil is energized with a pulse current having a predetermined frequency, the switch rotates by recognizing the change caused by the induced current in the body side coil when the switch switches from the energized state to the non-energized state. When there is no crossing, a cross break signal is output to stop the driving of the gluing roller.

  For this reason, since the terminal does not appear, waterproofing with a mold or the like is facilitated, and the power supply system to be removed at the time of cleaning can be eliminated from the gluing machine main body side. In addition, the gluing operation and the cleaning operation can be easily performed without worrying about getting wet.

  In a preferred embodiment of the present invention, the non-contact switch has at least one magnetization of two magnetic lead thin plates with a minute gap as a contact around one axis of the pressing roller. By providing a reed switch that switches according to the movement of the attached magnet piece, it is possible to detect a cross break with high accuracy.
