Description

  The present invention relates to a glue liquid supply pump for supplying glue liquid to a glue paste of a wallpaper glue machine, and a glue liquid for easily handling a detection detection signal conducting wire for transmitting a detection signal from a glue level liquid level detection sensor. It relates to a supply pump.

  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.

  Conventionally, there are manual and automatic wallpaper pasting machines. That is, the cross fed from the 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 the lower structure and a predetermined roller of the upper structure. .

  With the manual type device, pulling forward with the tip of the cloth, the part of the roller that holds the cloth up and down is rotated following rotation, and the other roller is rotated in conjunction with the gear to rotate the cloth into the gluing machine body. While being conveyed from the rear to the front, the glue is transferred from the roller to the back on the top of the roller that is pulling up the glue liquid in the glue halfway through its rotation, and sent out from the front with the glue applied. . 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.

  In such a wallpaper gluing machine, the use of an automatic wallpaper gluing machine is preferred in that efficient and uniform gluing can be performed. However, since the gluing machine is transported to the site and assembled there, disassembled after use and brought back and stored, it is desirable that it is small and lightweight. As a result of having a drive unit such as a motor and its controller unit, it is larger than a manual type unit, and its weight is also increased. Therefore, there is still a demand for a manual wallpaper pasting machine that is lightweight.

  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

  In an automatic wallpaper pasting machine equipped with a paste liquid supply pump, a power source for driving the paste liquid supply pump and its control are performed by a controller for the paste liquid supply pump attached to the controller of the automatic wallpaper pasting machine. This is because the drive motor of the conventional automatic wallpaper pasting machine and the drive motor of the slitter provided attached to the wallpaper pasting machine are driven by direct current power of 48V. This is because driving was convenient at a low voltage.

  However, when assuming a paste supply system that can be installed on a wallpaper pasting machine that does not have existing paste supply means, or in an automatic wallpaper pasting machine, the drive motor of the pasting machine itself and the output of the attached slitter can be output. In order to improve, when driving with 100V AC power is assumed, it is better to drive the paste liquid supply pump into low voltage DC power in the event of an electrical leakage accident.

  Therefore, apart from the wallpaper pasting machine, a controller for controlling the power supply to the paste liquid supply pump provided with converter means for converting AC power from the outside into DC power and supplying it to the paste liquid supply pump, Assuming that a signal from the liquid level detection sensor for detecting the glue liquid of the glue paste of the wallpaper pasting machine is transmitted to the controller, it has been found that the handling of the detection signal conductor is troublesome.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a paste liquid supply pump in which a detection signal conducting wire that transmits a signal from a glue level sensor is easy to route. Another object of the present invention is to obtain a paste liquid supply pump with little leakage of paste liquid when supplying paste liquid to the paste cake.

The paste liquid supply pump according to the invention described in claim 1 is attached to a wallpaper gluing machine including a glue pad, a glue raising roller arranged in the glue basket, and a glue roller contacting the glue roller. A paste liquid supply pump for supplying the paste liquid fed from the liquid supply pump into the paste basket,
A detection signal from a liquid level detection sensor for detecting the liquid level of the paste liquid in the paste basket is disposed in the vicinity of the paste liquid supply pump in the paste liquid supply hose coupled to the discharge port of the paste liquid supply pump. A detection signal conducting wire is arranged that communicates to a pump controller that controls the driving of the pump ,
The detection signal lead in the paste supply hose is connected between the outer wall of the introduction nozzle port for introducing the paste solution into the paste basket or the outer wall of the joint port connected to the paste solution supply hose of the connector engaged with the introduction nozzle and the inner wall of the hose. After being led out to the outside of the hose, it is connected to the output terminal of the liquid level detection sensor .

The glue liquid supply pump according to the invention described in claim 2 is coupled to the outer wall of the inlet nozzle port for introducing the glue liquid into the glue bag according to claim 1 or the glue liquid supply hose of the connector engaged with the inlet nozzle. The adhesive solution supply hose is coupled to the outer wall of the coupling port and the detection signal conducting wire through a waterproof shrinkable tube layer.

The paste liquid supply pump according to the invention described in claim 3 is a submersible pump in which the paste liquid supply pump according to claim 1 is immersed in the paste liquid supply container.
A detection signal conductor in the paste liquid supply hose is led out of the hose through the space between the outer wall of the pump outlet and the inner wall of the hose, and supplies power to the paste liquid supply pump and power supply of the pump body. It is characterized in that it is once introduced into the pump body from the side of the bushing disposed between the see-through with the lead wire port and then led to the pump controller through the insulating sheath of the power supply lead wire. .

  According to the present invention, since the detection signal conducting wire for transmitting a signal from the glue level detecting sensor is disposed in the paste supplying hose, it is possible to obtain a paste supplying pump in which the detection signal conducting can be easily routed. Further, since the paste liquid supply hose is coupled via the waterproof shrinkable tube layer, it is possible to obtain a paste liquid supply pump with little leakage of paste liquid even when the paste liquid is supplied to the paste cake.

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 paste supply pump for supplying the paste into the paste basket,
A signal from a liquid level detection sensor for detecting the liquid level of the paste liquid in the paste basket is disposed in the vicinity of the paste liquid supply pump in the paste liquid supply hose coupled to the discharge port of the paste liquid supply pump. Since the detection signal conducting wire that transmits to the pump controller that controls the driving of the pump is arranged, it is possible to obtain a glue liquid supply pump that can easily handle the detection signal conducting wire that transmits the signal from the glue level liquid level detection sensor.

  That is, it is an object to improve the output of the pasting machine drive motor and the attached slitter in the pasting machine supply system that can be attached to the pasting machine that does not include the existing pasting liquid supply means, and the automatic pasting machine. In the case of driving with 100 V AC power, a safety measure is preferably taken to convert the paste supply pump to a low voltage DC power source of less than 50 V using a secondary power source. For this reason, a controller for controlling the power supply to the paste liquid supply pump that includes converter means for converting AC power from the outside into DC power and supplying it to the paste liquid supply pump is separated from the wallpaper pasting machine. The signal from the liquid level detection sensor that detects the glue liquid of the glue paste of the wallpaper pasting machine is transmitted to the controller. The detection signal from the sensor is transmitted by wire or wireless. However, in the case of wireless, the cost of the apparatus is increased, so that the signal is transmitted by wire.

  Since the hose connected to the discharge port of the paste liquid supply pump is introduced into the glue basket of the wallpaper pasting machine, it is connected at least in the vicinity of the liquid level detection sensor. Further, since the controller controls the driving power of the paste liquid supply pump, a controller is disposed in the vicinity of the paste liquid supply pump. Therefore, the detection signal conducting wire is arranged along the hose for transmission of the detection signal by wire. However, since the detection signal conductor is thin and may be damaged, the operator needs to be careful. Therefore, in the present invention, by arranging the detection signal lead in the paste supply hose coupled to the discharge port of the paste supply pump, the detection signal lead is damaged because only the paste flows in the hose. There is no fear, there is no need to pay attention to the detection signal conductor for the operator, and there is an advantage that the handling is good.

  As the paste liquid supply pump of the present invention, any pump may be used as long as it supplies the paste liquid to the glue paste of the wallpaper glue machine by a hose connected to the pump discharge port. The pump liquid is supplied according to the detection signal from the liquid level detection sensor. If the drive is to be turned ON / OFF, there is no limitation. However, since the viscosity of the paste is high, a positive displacement pump is preferable. Further, as long as the paste liquid is supplied to the nozzle by the driving source, the style is not limited. For example, use an underwater pump that pumps the main body into the paste liquid of the paste liquid container, or a liquid feed pump that is arranged outside the paste liquid container and is distributed in the middle of the liquid feed pipe branched from the bottom of the container. Can do. As for volume pumps, 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, diaphragms A liquid pump such as a diaphragm pump that transports fluid by changing the volume of the piston, and a piston pump that transports fluid by reciprocating the piston is used.

  The pump controller of the present invention may be any pump controller that stops the operation of the drive source of the paste liquid supply pump by a detection signal from the liquid level detection sensor. For example, the pump drive is turned off by a detection signal issued when the level of glue paste exceeds a predetermined position, and if the detection signal is not issued, the pump drive is turned on. For example, the pump is turned on for a predetermined time by a detection signal that is generated when the liquid level of the soot falls below a predetermined position.

  The liquid level detection sensor of the present invention may be a liquid level of glue paste by the supplied glue liquid, regardless of whether it is non-detachably attached to the glue machine body or detachable from the glue machine body. As long as it is detected that the position exceeds the predetermined position. For example, a float type ON / OFF switch, an energization switch, a weight switch that generates a signal when a predetermined weight is exceeded, a weight sensor, and the like can be given. In addition, in the case of a paste liquid supply system that can be attached to a wallpaper pasting machine that does not include an existing paste liquid supply means, more preferably, it is arranged in parallel with the nozzle part and immersed in the liquid level for easy attachment / detachment. An energization switch including a pair of electrodes that are electrically connected to generate a detection signal is mentioned.

  As the paste liquid supply hose of the present invention, any liquid may be used as long as the liquid is fed from the discharge port of the paste liquid supply pump to the nozzle that is poured into the glue paste of the wallpaper pasting machine. Those having durability, flexibility and good handling are preferable. Preferably, hoses such as polyolefin resin, styrene resin, and vinyl chloride resin containing a reinforcing material are raised.

  The detection signal conducting wire of the present invention may be anything that transmits a detection signal from the liquid level detection sensor to the pump controller. As long as the liquid level detection sensor has a simple configuration in which a closed circuit is formed by energization when the paste reaches the upper limit level of the glue paste using a pair of detection electrodes, A pair of conductive wires that communicate with the detection electrode may be used. In this case, the pair of conductors are not arranged individually, but it is better to use a two-core coated conductor.

  The detection signal lead of the present invention is arranged in the paste supply hose coupled to the discharge port of the paste supply pump, and the detection signal lead is inserted into the inside from the outside or taken out from the inside in the middle of the hose. In order to do this, it is necessary to provide a through hole in a part of the hose wall, and the strength of the hose is cut by the through hole, and further, the glue liquid may leak. 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, as a preferred embodiment, the outer wall of the introduction nozzle port for introducing the paste liquid into the glue pad or the outer wall of the coupling port connected to the paste liquid supply hose of the connector engaged with the introduction nozzle and the inner wall of the hose is exposed to the outside of the hose. After being led out, it is connected to the output terminal of the liquid level detection sensor.

  As a more preferable aspect, an outer wall of an introduction nozzle port (for example, an elbow pipe 88 in an embodiment described later) or a hose connector (for example, an elbow supply in an embodiment described later) engaged with the introduction nozzle is introduced. The adhesive liquid supply hose is connected to the outer wall of the coupling port connected to the adhesive liquid supply hose of the tube 74) and the detection signal conductive line through a waterproof shrinkable tube layer, so that the detection signal conductive line is not damaged. The water leakage effect is also increased.

  Similarly, on the pump discharge port side, the hose is led out of the hose through the space between the pump discharge port and the hose inner wall in order to impair the strength of the hose and prevent liquid leakage from the through hole. Further, a waterproof shrinkable tube layer is provided on the outer wall of the introduction nozzle port for introducing the paste liquid into the glue pad or on the outer wall of the coupling port connected to the paste liquid supply hose of the connector engaged with the introduction nozzle and the detection signal lead wire. It may also be combined with the paste liquid supply hose. In particular, in the submersible pump in which the pump body is immersed in the paste liquid, the liquid leakage is not important, so there is little need to pass through the waterproof shrinkable tube layer.

  The detection signal conducting wire led out of the hose on the pump discharge port side is connected to a controller that controls the paste supply pump. Especially in submersible pumps, the outside of the hose is paste liquid, and it is troublesome to run the two lead wires, the power supply lead wire and the detection signal lead wire, because there is a risk of breakage caused by the detection signal lead wire. For this reason, the detection signal lead led out of the hose is temporarily put into the pump main body from the side of the bushing arranged between the mounting opening into which the power supply lead for driving the pump main body enters, and 2 of the power supply lead The structure is such that a lead is used to guide the controller. As a result, the paste liquid supply pump and the controller are connected by a conductor that also serves as a power supply power source, and the detection signal conductor does not appear on the surface, making it easy to handle and damage due to hooking of the detection signal conductor, etc. Less worry.

1. FIG. 1 is an explanatory diagram showing an example of the overall configuration of the side of a wallpaper pasting machine to which the paste liquid supply pump of the present invention is attached. 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.

FIG. 3 is an explanatory view showing the connection between the paste supply nozzle attachment and the paste supply hose attached to the wallpaper pasting machine of FIG. FIG. 4 is an explanatory view showing the coupling between the paste liquid supply pump and the paste liquid supply hose. FIG. 5 is an explanatory diagram showing the configuration of the detection signal conductor shown in FIGS. 3 and 4. FIG. 6 is an explanatory view of the bushing member of FIG. 5, wherein a is a front view and b is a side view.

  This embodiment describes a paste liquid supply pump in a paste liquid supply system including a nozzle attachment that can be attached to a wallpaper pasting machine that does not include an existing paste liquid supply means. As shown in FIG. 2, 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. The paste liquid supply pump 101 is a vane pump, and the main body of the pump is put into the paste liquid storage container 102 which is a 40L plastic bucket-like container (product name: regulator, manufactured by Yayoi Chemical Industry Co., Ltd.) that stores the paste liquid. It is a throw-in type submersible pump.

  As shown in FIG. 3, the paste liquid supply nozzle attachment 8 for 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. This is a member having an L-shaped cross section. 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. 2 and 7 by a detection signal conducting wire 87 connected to a connector terminal 86 formed on the upper surface of the nozzle body 81.

  The controller 100 for the pump is equipped with a converter for converting 100V AC power obtained from the external power source by the power cord 112 into 48V DC power, and the paste 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.

  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 main body of the pump 101, and the pump drive in which two cores for pump driving power and two cores for detection signal are coaxial. The power supply lead 109 was connected to the pump controller 100 disposed in the center of the middle dish portion 106 of the paste liquid storage container 102. Specifically, as shown in FIG. 3, 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 after the detection signal conducting wire 87 is fitted in the groove 90, After the detection signal conducting wire 87 was once covered with the waterproof shrinkable tube 99 on the bamboo joint type joint portion connected to the hose, it was attached to the hose 89. Since the detection signal conducting wire is a two-core coated wire, the waterproof shrinkable tube 99 was coated on the two-core exposed by peeling off the coating layer contacting the joint portion (a portion in FIG. 5). When the waterproof shrinkable tube 99 is heated with a dryer or the like, the diameter of the waterproof shrinkable tube 99 is reduced by heat to cover the joint and the joint.

  As shown in FIG. 4, the attachment structure of the detection signal conducting wire 87 on the paste liquid supply pump 101 side has also 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. Also in this joint part, the hose 89 was attached after peeling the coating layer which contact | abuts to a joint part, and exposing 2 cores (b part of FIG. 5). Note that the paste supply pump 101 of the present example is a submersible pump, and there is no problem with liquid leakage from the joint portion, so no waterproof shrinkable tube was attached.

  As shown in FIG. 5 and FIG. 6, the detection signal conductor 87 once taken out of the hose is between the hose power supply conductor 109, the power supply conductor, and the mounting opening through which the pump drive power supply conductor 109 of the pump 101 body enters. It introduced into the pump 101 main body from the side of the bushing 111 arranged. The bushing 111 has a water stop effect by being pressed toward the pump body by a bushing cover.

  The bushing 111 was produced by insert molding chloroprene rubber during vinyl chloride molding to give a double structure of soft vinyl chloride and chloroprene rubber. The reason why the chloroprene rubber is inserted is to secure the rebound resilience with the chloroprene rubber and to secure the water stop with the soft vinyl chloride, and the structure to secure the water stop structure by taking out the detection signal conductor 87 from the flange side when molding the vinyl chloride. did.

  With the above configuration, the paste supply nozzle attachment 8, the paste supply pump 101, and the controller 100 are connected by the hose and the lead that also serves as the power supply, and the lead that is electrically connected to the electrode does not appear on the surface. , Easier to handle and less worrying about breakage due to hooking wires.

  As shown in FIG. 2 and FIG. 7, 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. 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 in a part of the peripheral region.

3. Overall Configuration of Paste Supply Device FIG. 7 is an explanatory diagram showing a configuration when the paste supply device is stored. 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.

  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.

4). Paste supply pump 2
FIG. 8 is an explanatory view showing a configuration of a main part of another paste liquid supply pump. In the embodiment shown in the above-mentioned paste liquid supply pump 1, the configuration of the paste liquid supply system that can be attached to a wallpaper pasting machine that does not include the existing paste liquid supply means has been described. The controller of the paste supply pump provided is separate from the wallpaper pasting machine. In addition, the same thing as the number shown in FIG. 1 shows the same thing or an equivalent thing.

  The wallpaper pasting machine shown in FIG. 8 is provided with a through hole 75 that reaches the upper part of the glue basket 6 at the center of the back side of the pasting machine main body 1. The other end of the elbow supply pipe 74 serving as a hose connector connected to each other is inserted, and the paste liquid is supplied into the glue basket 6. In addition, although not shown, a part of the lower surface of the glue basket has a balance rod member that is inclined when the glue liquid pumped inside the glue cake is stored exceeding a predetermined balance amount. In addition, the front lower frame portion 46 of the gluing machine body is provided with a liquid level detection sensor for detecting that the balance member is tilted.

  The attachment structure of the elbow supply pipe 74 to the hose 89 was led out of the hose through the joint between the inner wall of the hose 89 and the bamboo joint joint portion of the outer wall of the elbow supply pipe 74, as in FIG. In addition, in order to prevent water leakage, the waterproof shrinkable tube 99 was covered as in FIG. That is, after the detection signal conductor 87 is passed through the outside of the portion connected to the hose 89 and then the bamboo joint type joint portion connected to the hose of the elbow supply pipe 74 is once covered with the waterproof shrinkable tube 99. The hose 89 was attached. When the waterproof shrinkable tube 99 is heated with a dryer or the like, the diameter of the waterproof shrinkable tube 99 is reduced by heat to cover the joint and the joint.

  When the elbow supply pipe 74 is inserted into the through hole 75, the derived signal detection lead 87 is attached to a terminal 72 that is coupled to the detection signal connector 73 above the through hole 75. Due to the connection between the terminal 72 and the detection signal connector 73, the detection signal of the liquid level detection sensor that detects that the balance member is tilted is transmitted to the detection signal conducting wire.

  As described above, the paste liquid supply pump according to the present invention has the detection signal conductor from the liquid level detection sensor arranged inside the paste liquid supply pump, so there is little need to worry about breakage of the detection signal conductor, and handling is easy.
