  Currently, it is common to apply wall coverings to interior wall surfaces in interior construction of buildings while applying glue continuously to sheet-like wall coverings using a dedicated wallpaper pasting machine on site. It has become. The general configuration of such a wallpaper gluing machine is that a gluing machine body composed of an upper structure and a lower structure in which a plurality of rollers are arranged is placed on a support leg, and between the upper and lower structures. While the sheet-like wall covering material (hereinafter referred to as a cross) sandwiched between the two is conveyed by a roller, the paste is glued from the glue of the lower structure by the roller, and transferred onto the back surface of the wall covering material.

  In addition, the automatic wallpaper pasting machine is equipped with a paste supply pump to reduce the size and weight of the pasting machine main body and to reduce the size of the glue paste so that it will not be supplied frequently. Automatic wallpaper pasting machines have been put to practical use (for example, see Patent Document 1).

JP 2002-102777 A

  The glue supply pump that does not frequently supply paste liquid is very convenient for the user. Before the automatic wallpaper pasting machine equipped with the paste liquid supply pump was put into practical use, The requests from the owner of the automatic wallpaper pasting machine were unending.

  The present invention provides a glue liquid supply nozzle attachment for a wallpaper glue machine that can supply glue liquid from a glue liquid supply pump without pulling out glue paste even in a wallpaper glue machine without a glue liquid supply pump. It is another object of the present invention to obtain a glue liquid supply nozzle attachment for a wallpaper pasting machine that can automatically supply a glue liquid when the glue liquid in the glue basket is reduced.

According to a fourth aspect of the present invention, there is provided a paste supply nozzle attachment for a wallpaper pasting machine, wherein the detection electrode according to the third aspect includes a first detection electrode and a second detection electrode, and the nozzle body is The first detection electrode is positioned below the lower nozzle port and the second detection electrode is positioned above the first detection electrode while being fixed to the wallpaper pasting machine body at the height position by the fixture. It is characterized by being located.

State claimed wallpaper pasting machine size supplying nozzle attachment according to the invention according to claim 5, in which the nozzle body according to claim 4 is fixed to the wallpaper pasting machine body in the vertical position by the fastener The first detection electrode and the second detection electrode are arranged at positions separated from each other with the rotation axis of the gluing roller therebetween.

  According to the nozzle attachment of the present invention, the paste liquid can be supplied from the paste liquid supply pump without pulling out the glue in the wallpaper pasting machine not including the paste liquid supply pump. Furthermore, there is an effect that it is possible to automatically supply the paste liquid when the paste liquid in the paste basket is reduced.

In the present invention, the paste liquid that is mounted on a wallpaper pasteurizing machine that includes a glue paste, a glue raising roller disposed in the glue basket, and a glue roller that contacts the glue lifter and is fed from the glue supply pump A nozzle attachment for feeding into the glue basket,
A nozzle body that can be fixed to the wallpaper pasting machine main body in a state of being inserted into a facing gap between the side plate of the wallpaper pasting machine main body and the end of the pasting roller;
A fixing tool for removably fixing the nozzle body to a predetermined height position with respect to the wallpaper pasting machine body;
In the nozzle body, an upper connection port for connecting a hose from the paste liquid supply pump in a state where the nozzle body is fixed to the wallpaper pasting machine body at the height position by a fixture, and the upper connection port And a lower nozzle port through which the glue solution flowing into the paste flows down into the glue basket. For this reason, the paste liquid can be supplied from the paste liquid supply pump without drawing out the glue.

  In other words, the gluing roller of the wallpaper gluing machine is driven in conjunction with other rollers such as a vertical pinch roller that feeds sheet-like wall coverings forward, whether it is a manual wallpaper gluing machine or an automatic wallpaper gluing machine driven by a motor. Therefore, a gear is arranged on one of the shaft support portions. A gap of about 25 mm is formed between the one end surface of the gluing roller and the side wall surface of the lower structure for movement of the glue liquid between the front and the rear when the glue raising roller is used as a boundary. By providing a nozzle main body having a thickness that can be inserted into the gap and its fixing tool, the paste liquid is continuously supplied from the paste liquid supply pump without drawing the glue cake arranged to be drawn into the lower structure. It becomes possible.

  As the nozzle body of the present invention, when it is fixed to the gluing machine main body with a fixture, the gap between the one end surface of the gluing roller and the side plate of the gluing machine body facing the gluing roller that rotates is not touched. What is necessary is just to provide the thickness which can be arranged. Since the cross-sectional area at the tip of the nozzle body is the same as the cross-sectional area of the pipe up to the tip of the nozzle body, it is wide. A preferable nozzle tip has a substantially rectangular cross section, a thickness of 10 to 20 mm, preferably around 15 mm, and a width of 40 to 50 mm. This is because if the width is larger than 50 mm, it will be caught by the glue roller and the lower pinch roller when the upper structure is opened and closed.

  As a fixing tool of the present invention, the nozzle main body is detachably fixed at a predetermined height position with respect to the wallpaper pasting machine main body toward the inside of the glue basket disposed below the roller. That's fine. Fixing to the main body of the gluing machine includes, for example, fixing forms such as screwing, fitting / clamping by clip means, sticking by sticking means such as hook-and-loop fasteners, hooking by hooking members, etc. As long as it is securely fixed. Specifically, in order to securely fix the nozzle body, the nozzle fixing base on which the nozzle body is mounted is previously attached to the gluing machine body, preferably the upper structure (to frequently open and close the upper structure by attaching a cloth or the like). ) Securely fix with screws, etc., and attach the nozzle to the base.

  In the wallpaper gluing machine, the upper structure can be opened and closed by a hinge arranged on the front side with respect to the lower structure provided with the glue paste and the gluing roller. This is because a sheet-like wall covering material is disposed between the upper structure and the lower structure, and is sandwiched between the pressing roller, the upper pinch roller, and the like of the upper structure and the gluing roller and the lower pinch roller. Therefore, the place where the nozzle is fixed to the gluing machine main body by the fixing means is opened and closed each time the wall covering is replaced, and therefore, the upper structure is preferable, and it is preferable that the upper structure is arranged to be openable and closable.

  The nozzle body of the present invention has an upper connection port for connecting a hose from the paste liquid supply pump in a state where the nozzle body is fixed to the wallpaper pasting machine body at the height position by a fixture, and an upper connection. A lower nozzle port is provided for allowing the glue solution flowing into the mouth to flow down into the glue basket.

  Preferably, the nozzle body of the present invention is integrally provided with a sensor unit having a pair of detection electrodes for detecting the level of the paste liquid in the glue basket. As the sensor unit, any sensor unit that can be attached to and detached from the gluing machine main body and detects that the level of the glue paste by the supplied glue solution has exceeded a predetermined position may be used. Specifically, a float type ON / OFF switch and an energization switch are mentioned. More preferably, there is an energizing switch provided with a pair of electrodes that are arranged side by side in the nozzle body for easy attachment and detachment and are electrically connected to emit a detection signal when immersed in a liquid level. As a preferred embodiment, the lower nozzle port may be provided with a liquid level detection sensor unit that detects that the level of the glue paste by the supplied glue liquid has exceeded a predetermined position.

  In addition, since the pair of detection electrodes may be energized when the glue solution reaches the glue liquid surface level position of the upper limit of the glue cake to form a closed circuit, the two electrodes have the same length or two Of the detection electrodes, the length of the short detection electrode only needs to be at the level of the glue liquid level. However, if the length is the same, sufficient conduction does not occur even if the upper limit level is exceeded, and erroneous detection may occur. In particular, since the glue moves forward with the rotation of the glue raising roller, it is preferable to lengthen the electrode near the nozzle.

  Therefore, as a more preferable aspect, the detection electrode includes the first detection electrode and the second detection electrode, and the nozzle body is fixed to the wallpaper pasting machine body at the height position by the fixture. One detection electrode is located below the lower nozzle port, and the second detection electrode is located above the first detection electrode. As a result, it is detected that the second detection electrode has passed the position of the second detection electrode due to contact with the paste liquid, and there are few false detections. The detection signal of the sensor unit is transmitted to a controller that controls the driving of the paste liquid supply pump that discharges the paste liquid through a hose connected to the upper connection port of the nozzle body.

  As a more preferable example of the pair of detection electrodes, the first detection electrode and the second detection electrode are attached to the gluing roller in a state where the nozzle main body is fixed to the wallpaper pasting machine main body at the height position by the fixture. The thing arrange | positioned in the position which mutually separated with the rotating shaft in between is mentioned. In other words, the pair of electrodes hang down from the two positions separated across the glue roller shaft to the uppermost glue liquid level of the glue cake. The reason why the first electrode and the second electrode are separated from each other is that the glue is viscous, and therefore, when the electrodes are close to each other, there is a possibility that the glue is always conductive. Further, these detection electrodes are preferably set to 5 mmφ or more, more preferably 8 mmφ or more, because the height position of the sensor may not be accurate when the diameter is 1 mmφ or less.

  Note that the control of the controller of the paste liquid supply pump only needs to stop the operation of the drive source of the paste liquid supply pump by the detection signal from the sensor unit. For example, the operation of the paste supply pump may be stopped while the detection signal is transmitted. As a result, the detection signal is not transmitted when the amount of glue liquid in the glue basket decreases, the pump is driven to supply glue liquid, and the pump is driven when the second detection electrode position is exceeded. To stop. As a result, the paste liquid is automatically supplied to the glue pad, and when the glue is sufficiently supplied to the glue pad, the supply of the paste liquid can be automatically stopped.

  The glue supply pump connected to the nozzle body of the present invention is not limited as long as the pump drive is turned ON / OFF according to the detection signal, but the viscosity of the glue liquid is high. A volumetric pump is preferred. Further, as long as the paste liquid is supplied to the nozzle by the driving source, the style is not limited. For example, a submersible pump that pumps into and out of the paste liquid container holding the paste liquid, or a liquid feed pump that is arranged outside the paste liquid container and is arranged in the middle of the liquid feed pipe branched from the lower part of the container is used. be able to. As for the liquid feed pump type, gear pumps that engage gears, screw pumps that transport with screw-type rotors, vane pumps that transport liquid with movable vanes attached to rotors that are mounted eccentrically on the casing, Liquid pumps such as a diaphragm pump that transports fluid by changing the volume of the diaphragm and a piston pump that transports fluid by reciprocating movement of a piston are used.

  The detection signal by the sensor unit of the present invention may be transmitted to the controller by wire or wireless. The hose connected to the upper connection port of the nozzle body is connected to the discharge port of the glue supply pump, and the controller controls the drive power of the glue liquid supply pump. Has been placed. Therefore, the detection signal conducting wire is arranged along the hose for transmission of the detection signal by wire. However, since the detection signal conducting wire is thin, there is a risk of damage, so the operator needs to be careful. Therefore, it is preferable to place the detection signal conductor inside the hose so that only the glue liquid circulates inside the hose, so there is no possibility of damaging the detection signal conductor, and the operator does not pay attention to the detection signal conductor. There is an advantage that it is easy to handle.

  However, in order to put the detection signal conductor in the middle of the hose, it is necessary to provide a through hole in a part of the hose wall, and the glue liquid may leak from the through hole. In particular, if leaked glue liquid adheres to the wallpaper pasting machine, it will stain the cloth cover and cause a malfunction of the pasting machine. Therefore, a configuration in which the nozzle body is led out of the hose through the outer wall of the upper connection port of the nozzle body and the inner wall of the hose is adopted. Specifically, the glue supply hose is connected to the outer wall of the upper connection port of the nozzle body and the detection signal conductor via a waterproof shrinkable tube layer, so that the detection signal conductor is not damaged and the water leakage effect is obtained. Also gets higher.

1. FIG. 1 is an explanatory diagram showing the overall lateral configuration of a wallpaper pasting machine equipped with a paste supply nozzle attachment for a wallpaper pasting machine of the present invention. As shown in FIG. 1, the wallpaper gluing machine includes a gluing machine main body 1, a pedestal portion 2 on which the gluing machine main body 1 is placed, and a pedestal portion for supporting the gluing machine main body 1 at a predetermined height. 2 comprises a leg portion 3 composed of a front leg 31 and a rear leg 32 arranged in pairs at the front left and right ends.

  A cross receiving bracket 33 is rotatably arranged on the pair of rear legs 32, and a cross core rod 34 that is passed through the center of the raw roll R is pivotally supported at the tip of the cross receiving bracket 33. ing. The wall covering material (cross) C fed out from the raw roll R is brought into contact with the first tension bar 36 horizontally mounted on the folding portion 35 of the rear leg 32 and is given a drawing load at the drawing port.

  The gluing machine main body 1 is composed of a lower structure 4 mainly composed of a glue basket 6 and an upper structure 5 mounted thereon so as to be openable and closable around a pair of hinges 45 provided on the front left and right of the main body. As the rollers rotate, the gluing roller 41 that continuously abuts against the back surface of the cloth conveyed forward from the rear side of the gluing machine main body 1 while rotating is applied to the left and right side walls of the lower structure 4. The shaft support plate is pivotally supported so as to be placed in the glue basket 6 as much as possible. A glue raising roller 61 that scrapes up the glue in the glue basket 6 by rotation and transfers it to the glue roller 41 is pivotally supported on both side surfaces of the glue basket 6 at positions closer to the rear side than the center.

  The gluing roller 41 is connected to a rotation shaft of a controller (not shown) provided with an electric motor that is a drive source that is detachably attached to the gluing machine body 1. The rotation axis of the gluing roller 41 fixed to the side plate of the glue plate 6 is a lower pinch roller 42 disposed on the lower structure 4, a doctor roller 43, a leveling roller 44, and a measuring roller disposed on the upper structure 5. The upper pinch roller 51, the pressing roller 52, and the drive roller 53 that are used are interlocked with a rotation shaft of a predetermined roller through a gear.

  Along with the rotation of the gluing roller 41, the other rollers to which the rotational motion is transmitted via the gear also rotate to convey the cloth C sandwiched between the upper and lower structures from the rear to the front, and in the middle of the gluing roller The glue pulled up from the glue basket 6 when being conveyed on 41 is transferred and applied to the back surface of the cloth. Moreover, the slitter 7 is provided in the rear surface side of the gluing machine main body 1 of a present Example.

  The length in the longitudinal direction of each roller including the gluing roller 41 and the glue raising roller 61 conforms to the length in the longitudinal direction of the glue basket 6. In other words, the length of the glue raising roller 61 arranged in the glue basket 6 must be shorter than the length of the glue basket 6 in the longitudinal direction. Moreover, a gap of about 25 mm is formed between both side walls of the glue basket 6 and both roller end faces of the glue raising roller 61 in order to facilitate the movement of the glue liquid in the glue basket 6. Accordingly, the length of the glue raising roller 61 is determined, and since the glue is not transferred to the cloth with the glue roller 41 longer than the length of the glue raising roller 61, the length of the glue roller 41 is also determined. Therefore, gaps are formed on both sides of the gluing machine body 1 from above into the glue basket.

  A paste supply nozzle attachment 8 is disposed in at least one of the gaps. Two glue liquid supply nozzle attachments 8 may be disposed in each of the gaps formed on both sides of the gluing machine main body 1. However, the hose serving as a liquid supply pipe from the pump and the control of the pump may be provided. If there is a problem and the supply of the paste liquid can be sufficiently covered with one nozzle, two nozzles are unnecessary.

2. FIG. 2 is an explanatory view showing a lateral internal configuration of the main body of the wallpaper pasting machine in FIG. 1 including the pasting liquid supply nozzle attachment for the wallpaper pasting machine. FIG. 3 is a rear view of a main part of the side of the wallpaper pasting machine main body of FIG. 1 including the paste supply nozzle attachment for the wallpaper pasting machine. FIG. 4 is an explanatory view showing the configuration of the paste supply nozzle attachment for the wallpaper pasting machine of the present invention. FIG. 4 is a side view of the paste supply nozzle attachment for the wallpaper paste pasting machine extracted from FIG. It is a rear view of the paste supply nozzle attachment for wallpaper pasting machines extracted from FIG.

  As shown in FIGS. 2 to 4, the paste supply nozzle attachment 8 for a wallpaper pasting machine includes a nozzle body 81 that can be attached to and detached from each other, and a fixture 91 thereof. The nozzle fixture 91 includes a pedestal member 92 that comes into contact with the front and rear frames 55 and 56 connecting the both side walls of the upper structure 5 of the gluing machine body 1 from the lower surface side, and a rising member 93 that rises from one end edge of the pedestal member 92. It consists of. The base member 92 is formed with a rectangular hole 94 into which the tip of the nozzle body 81 is inserted.

  The rising member 93 of the fixture 91 is formed with a handle hole 97 that matches the handle hole 57 of the upper structure 5, and a screw hole 98 that matches the screw hole 58 formed on the upper side of the handle hole 57 of the upper structure 5. The inner thick piece 59 attached to the upper side of the handle hole 57 of the upper structure 5 is removed together with a screw, and the handle hole 97 of the rising member 93 is replaced with the handle hole 57 of the upper structure 5 instead of the thick piece 59. And are fixed to the corresponding screw holes 58 and 98 with screws.

  The tip end portion of the nozzle body 81 is mounted in the hole 94 of the nozzle fixture 91 attached to the upper structure 5, and the retaining piece 82 protruding from the handle hole 97 side of the nozzle body 81 is placed on the handle hole 97. The nozzle body 81 is fixed to the nozzle fixture 91 by being hooked on the edge. A hose 89 as a liquid supply pipe from the paste liquid supply pump is attached to the rear end portion of the nozzle main body 81 through an elbow pipe 88 that is rotatably attached to the nozzle main body 81 as an upper connection port.

  In the nozzle body 81, a pair of detection electrodes 84 and 85 are arranged in parallel with a nozzle discharge port 83 that supplies the paste liquid into the paste basket 6. These are a first detection electrode 84 installed on the lower end wall of the nozzle outlet 83 and a second detection electrode 85 installed across the gluing roller 41. Each electrode is connected to the pump controller 100 shown in FIGS. 5 and 6 by a detection signal conducting wire 87 connected to a connector terminal 86 formed on the upper surface of the nozzle body 81.

  The pair of detection electrodes 84 and 85 installed at the position straddling the gluing roller 41 is longer in the first detection electrode 84 and is immersed in the paste liquid in the paste basket 6 in a low water level, and the second The detection electrode 85 is suspended down to the uppermost glue liquid level of the glue basket 6. The electrodes 84 and 85 were 8 mmφ electrode rods. It should be noted that the two electrodes 84 and 85 may be energized when the glue solution reaches the glue liquid level level position of the upper limit of the glue cake to form a closed circuit. It is only necessary that the short electrode length of the two electrodes is the position of the glue liquid level.

  The pump controller 100 is equipped with a converter that converts 100V AC power as an external power source into 48V DC power by a power cord 112, and the paste liquid supply pump 101 is driven by 48V DC power. Also, the sensor 100 measures the amount of glue in the glue pad of the gluing machine by molding the inner wiring and converter part of the controller 100 itself, and molding the 100V power supply terminal from the outside, the power feeding terminal to the glue supply pump. The signal supply terminal etc. from the etc. was made into a waterproof shield structure, and the short circuit by glue liquid was prevented. As a result, even in the event of a leakage from the pump 101, the safety of workers and equipment is ensured.

3. Overall Configuration of Paste Solution Supply Device FIG. 5 is an explanatory view showing the configuration of the paste solution supply device. FIG. 6 is an explanatory view showing a configuration when the paste liquid supply device is stored. As shown in the figure, the nozzle body 81 of the paste liquid supply nozzle attachment 8 attached to the upper structure 5 of the pasting machine body 1 is communicated with the discharge port of the paste liquid supply pump 101 via the hose 89. As shown in FIG. 5, the paste liquid supply pump 101 is a vane pump, and is a 40L plastic bucket-like container (trade name: regulator, manufactured by Yayoi Chemical Industry Co., Ltd.) that stores paste liquid. It is a throw-in type submersible pump that puts the pump body inside.

  The detection signal conductor 87 connected to the two detection electrodes 84 and 85 passes through the inside of the hose 89 and once enters the pump body 101, and the pump drive is made by coaxially connecting the two cores for the pump driving power and the two cores for the detection signal. The power supply lead 109 is connected to the pump controller 100 arranged at the center of the middle dish portion 106 of the paste liquid storage container 102. Specifically, a groove 90 through which the detection signal conducting wire 87 is passed is formed outside the portion of the elbow pipe 88 that is connected to the hose 89, and the detection signal conducting wire 87 is fitted in the groove 90 and then connected to the hose of the elbow pipe 88. After the detection signal conducting wire 87 was once covered with a waterproof shrinkable tube 99 on the joint portion of the joint portion, the joint portion was attached to the hose 89. Since the detection signal conductor is a two-core coated wire, the waterproof shrinkable tube 99 was coated after the two-core was exposed by peeling off the coating layer contacting the joint portion. The waterproof shrinkable tube 99 is heated by a dryer or the like, so that the diameter is reduced to cover the joint and the joint.

  Further, the mounting structure of the detection signal conducting wire 87 on the paste liquid supply pump 101 side has been devised. Similarly to the elbow pipe 88 at the upper connection port, the detection signal conducting wire 87 was passed out of the hose through the space between the inner wall of the hose and the bamboo joint type portion of the outer wall of the pump discharge port. In addition, since it is a submersible pump, since the liquid leakage from a joint part does not have much problem, the shrinkable tube for waterproofing was not attached. The detection signal lead 87 once taken out of the hose is once inserted into the pump main body from the side of the bushing 111 arranged between the mounting opening in which the power supply lead 109 for driving the pump 101 main body is inserted. The two cores 109 were led to the controller 100. The bushing 111 produced by insert molding of chloroprene rubber at the time of PVC molding had a double structure of soft PVC and chloroprene rubber. The reason why rubber is inserted is that chloroprene rubber ensures rebound resilience and soft PVC ensures water stoppage. It was set as the structure which ensures a water stop structure by taking out the detection signal conducting wire 87 from the flange side at the time of vinyl chloride molding.

  With the above configuration, the glue liquid supply nozzle attachment 8, the glue liquid supply pump 101, and the controller 100 are connected by the hose and the conductive wire 109 that also serves as the power supply power source, and the detection signal conductive line that is electrically connected to the electrode is displayed. Therefore, handling is easy, and there is less concern about damage due to hooking of detection signal conductors.

  The paste liquid storage container 102 is attached to a carriage 103 provided with three or more casters so as to be movable. Specifically, the storage container 102 is fixed by a rising frame 104 formed along the outer periphery of the carriage 103 and an engaging band 105 partially fixed to the rising frame 104. Specifically, the storage container 102 is placed inside the rising frame 104, and the outer peripheral wall of the bottom surface of the container 102 is fastened with the engagement band 105 and attached to the carriage 103.

  As shown in FIG. 6, the middle plate portion 106 is formed with an annular partition wall 108 that rises so as to surround the controller 100 fixed at the center with a thumbscrew and separates from the surrounding region. In part, a through hole 110 through which the hose 89 and the pump drive power supply lead 109 from the paste supply pump 101 pass is formed.

  Further, the middle plate portion 106 of the paste liquid storage container 102 can be covered with an upper cover (not shown) while being attached, and a handle 107 formed facing the upper portion of the side wall of the main body of the container 102 can be raised and hooked. In order to prevent the humidity inside the container 102 from adversely affecting the controller 100, the upper lid may be provided with a ventilation opening in the center of the upper lid. Furthermore, a notch corresponding to the handle portion may be provided in the rising frame 104 so that the above-described carriage 103 can be placed when the handle 107 is raised.

  In this embodiment, the controller 100 also devised the operation control of the paste liquid supply pump 101. First, since the water level of the supply port in the paste tank is extremely high due to viscosity during pump operation, a fixed time lag (about 1 second) was given to the pump operation. In addition, a function to automatically stop the pump after 5 minutes of continuous use has been added to the pump to prevent overheating.

  As described above, the paste supply nozzle attachment for the wallpaper pasting machine of the present invention can be easily mounted even in the wallpaper pasting machine not equipped with the paste supply pump, and can automatically supply the paste liquid. Therefore, the pasting machine that has already been purchased and used can also be provided with the function of automatically supplying the paste.
