[Industrial application fields]
The present invention relates to a method and an apparatus for arranging a hot water pipe in a pipe housing groove formed on one side of a base material for a floor heating panel when manufacturing a hot water type floor heating panel. The present invention also relates to a method of manufacturing a hot water floor heating panel using the above method, and a hot water floor heating panel manufactured by the method.
[0002]
[Prior art]
In a hot water type floor heating panel, usually, a hot water pipe made of a synthetic resin pipe having flexibility is arranged in a pipe housing groove formed on one side of a floor heating panel base material, and the arranged hot water pipe is It is manufactured by bonding a covering member to one side of the substrate so as to cover it.
[0003]
Here, the operation of disposing the hot water pipe in the pipe housing groove of the base material is normally performed in a state where the base material is placed on a horizontal base of the height of the operator's waist. In addition, when the base material is a large one of about 3000 mm × 1800 mm, for example, an operator rides on the base material placed on a horizontal table, and pipes are arranged in this state. .
[0004]
[Problems to be solved by the invention]
However, the above-described pipe placement work forces the operator to bend and stretch the waist, knees, and the like, and thus places a heavy burden on the operator's body, particularly on the waist.
[0005]
In addition, when the size of the base material is large and the operator needs to get on the pipe and perform pipe placement work, the burden on the operator's waist and neck is further increased. In addition, in the above case, it is difficult for one person to work, and it is usually performed by two or more workers.
[0006]
Furthermore, when manufacturing a hot water floor heating panel, an adhesive for joining the covering member is applied in advance to one side of the base material, and the pipe is disposed in a state where the adhesive is dry to the touch. is there. However, in this case, since the operator cannot get on the base material even if the size of the base material is large, it is very difficult to arrange the pipes.
[0007]
The object of the present invention is to reduce the physical burden on the worker when the hot water pipe is installed on the base material in the production of the hot water type floor heating panel, and to save labor for the work. It is to facilitate the operation of arranging the hot water pipe in a state in which an adhesive is applied in advance.
[0008]
[Means for Solving the Problems and Effects of the Invention]
In the method for arranging hot water pipes according to the present invention, a floor heating panel base material having a pipe receiving groove formed on one side is placed and fixed on a movable base plate in a horizontal state, and then the movable base plate is tilted or vertically. In this state, the hot water pipe is disposed in the pipe receiving groove of the base material, and then the movable base plate is returned to the horizontal position to remove the base material from the movable base plate.
[0009]
In the above method, the hot water pipe can be arranged in a state where the base material is erected obliquely or vertically together with the movable base plate. Therefore, according to the above method, the operator does not need to bend and stretch the waist, knees and the like as in the prior art, and can perform the pipe placement work in an easy posture while standing normally. The physical burden on the operator is greatly reduced. Further, according to the above method, even when the size of the base material is large, only one person can perform the work of arranging the hot water pipe, so that labor saving is possible. Furthermore, according to the above method, even when an adhesive for joining the covering member is applied to one side of the base material in advance, it is easy to dispose the hot water pipe regardless of the size of the base material. Can be done.
[0010]
In the hot water pipe disposing method according to the present invention, the gradient of the movable base plate in the standing state is preferably 50 ° to 90 °, more preferably 60 ° to 80 °.
[0011]
If the gradient of the movable base plate in the standing state is less than 50 °, the base material placed and fixed on the movable base plate in the same state is separated from the operator, and the hot water pipe installation work becomes difficult. On the other hand, if the slope exceeds 90 °, it is necessary for the operator to face upward, so that the pipe installation work is difficult to perform and a burden is imposed on the operator's neck.
[0012]
In the hot water pipe disposing method according to the present invention, the hot water pipe may be disposed in the pipe receiving groove of the base material while intermittently moving the movable base plate in the standing state upward or downward by an arbitrary distance. .
[0013]
The pipe receiving groove formed in the base material is usually a meandering pattern in which straight portions and curved portions are mixed, but as described above, the movable base plate is intermittently moved at an arbitrary distance upward or downward. Since the hot water pipe can be disposed at a substantially constant height, the work is easy and the work efficiency is improved.
[0014]
In the above, the moving distance of the movable base plate in the upright state may be determined as appropriate so that the pipe placement work is easy in consideration of the pattern of the pipe housing groove of the base material, etc., but usually about 30 to 80 cm It is made.
[0015]
The present invention also includes a method for manufacturing a hot water floor heating panel. This method includes a step of disposing a hot water pipe in a pipe housing groove of a base material for a floor heating panel by the above disposing method according to the present invention, and a covering member on one side of the base material so as to cover the disposed hot water pipe. The process of joining.
[0016]
According to the above method, in the hot water pipe arranging step, the physical burden on the operator is small, and even when the base material is large, the work can be performed by one person, and the bonding for joining the covering members is possible. Even when the agent is previously applied to one side of the base material, the operation of arranging the hot water pipe can be easily performed regardless of the size of the base material. Therefore, according to the above method, the working efficiency can be remarkably improved, and the productivity is increased.
[0017]

[0018]
According to the floor heating panel described above, since the hot water pipe is arranged in a good condition in the pipe housing groove of the base material, production defects due to the arrangement of the hot water pipe are extremely small.
[0019]
As a hot water pipe, what is usually used as an object for floor heating panels can be adopted as it is, for example, it is constituted by a synthetic resin pipe having an outer diameter of about 4 to 15 mm.
[0020]
A base material is comprised with a synthetic resin hard foam, a synthetic resin soft foam, a wooden material, etc. The pipe housing groove may be formed on either the upper surface or the lower surface of the substrate. The pipe housing groove is constituted by a U groove, a square groove, or the like. The pattern of the pipe receiving groove is constituted by a meandering pattern in which straight portions and curved portions are mixed.
[0021]
The covering member is joined to one side of the base material to prevent the hot water pipe from falling off and to ensure the flatness of the pipe disposition surface, and is usually composed of various sheet materials, plate materials, and the like.
[0022]
The floor heating panel may be constituted by a single panel, or may be formed by connecting a plurality of panel units so as to be foldable or rollable.
[0023]
Next, a hot water pipe disposing apparatus according to the present invention is an apparatus for disposing a hot water pipe in a pipe housing groove formed on one side of a base for a floor heating panel, and a horizontal straight portion extending in the front-rear direction and A rail having a rising straight portion extending obliquely upward or vertically upward from the front end of the horizontal straight portion via a curved portion, a movable base plate that is movable along the rail and can be fixed on the base, and movable And a work platform provided so that an operator can face the movable base plate located at the rising straight portion of the rail, and the horizontal straight portion of the rail is connected to the movable base plate.

Therefore, according to the above apparatus, the worker can perform the work of arranging the hot water pipe while standing on the work table and facing the base material in a state of being tilted or vertically with the movable base plate, Since the waist and knees are not forced to bend and stretch as in the prior art, the physical burden on the operator accompanying the installation work is greatly reduced. Moreover, according to the said apparatus, arrangement | positioning operation | work of a hot water pipe can be performed only by one person irrespective of the size of a base material, and it can aim at labor saving. Furthermore, according to the above apparatus, even when the adhesive for joining the covering member is previously applied to one side of the base material, the hot water pipe can be easily arranged regardless of the size of the base material. Can be done.
[0025]
In the above apparatus, one rail is usually provided at least on the left and right sides, but one or more intermediate rails may be provided between the left and right rails. The structure of the rail may be appropriately determined according to the structure of the movable base plate and the movable base plate driving means, but for example, the left and right rails are rolling elements such as running rollers provided on the movable base plate. The lower rail member that can be used, and the upper rail member that is disposed above the lower rail member at a required interval so as to prevent the rolling elements from falling off. The rail is supported and fixed by appropriate support means.
[0026]
In the hot water pipe arranging device according to the present invention, the gradient of the rising straight portion of the rail is preferably 50 ° to 90 °, more preferably 60 ° to 80 °.
[0027]
If the slope of the rising straight portion of the rail is less than 50 °, the base material placed and fixed on the movable base plate is too far away from the work table in the disposing work station including the rising straight portion, and the hot water pipe is arranged. Installation work may be difficult. On the other hand, if the gradient exceeds 90 °, it is necessary for the worker to face upward when the hot water pipe is disposed, so that the work is difficult to perform and a burden is imposed on the neck of the worker.
[0028]
The horizontal straight line portion of the rail may be slightly inclined as long as it does not hinder the attachment / detachment of the base material, in addition to the case where it is completely horizontal.
[0029]
The curved portion of the rail is not limited as long as the movable base plate can pass through without any problem, and it is not always necessary that the curved portion is configured by a curve, and may be partially configured by a straight line. Absent.
[0030]
In the hot water pipe disposing device according to the present invention, a plurality of movable base plates may be arranged in the front-rear direction, and adjacent movable base plates may be connected to bend freely.
[0031]
In the above case, the hot water pipe placement work on a plurality of base materials can be performed collectively, so that the work efficiency can be improved. Further, in the above case, since the adjacent movable base plates are connected so as to be bent, there is no problem even when the movable base plate passes through the curved portion of the rail, and the movement is smooth. However, even in the above case, it is not always necessary to place and fix the base material on all the movable base plates, and it is sufficient that the base material is placed and fixed on at least one movable base plate. As a connecting means between adjacent movable base plates, a hinge is usually used.
[0032]
It should be noted that at least one movable base plate may be used, and the present invention is not limited to the case where a plurality of movable base plates are provided as described above.
[0033]
As moving means for the movable base plate, usually, a required number of rolling elements such as running rollers that can roll on the rail are provided on the lower surface of the movable base plate. However, the moving means of the movable base plate is not limited to the above. For example, a part or the whole of the rail may be configured by a roller conveyor, and the movable base plate may be attached to the conveyor.
[0034]
In the hot water pipe disposing device according to the present invention, the movable base plate includes a pair of rulers that can clamp and fix the base material placed on the left and right sides, and at least one of the rulers is provided on the movable base plate. It may be a movable ruler that can be detachably attached.
[0035]
According to the above configuration, the base material can be easily and quickly fixed to the movable base plate by the pair of rulers, and similarly, the base material can be easily detached from the movable base plate.
[0036]
In the above case, at least the lower surface of the movable ruler is made of a magnetic material, and the movable ruler has a groove width larger than the width of the movable ruler and a groove depth smaller than the height of the movable ruler on the upper surface of the movable base plate. One or a plurality of receiving grooves are formed at intervals in the left-right direction, and a magnet is embedded at the bottom of the groove so as to be substantially flush with the groove, and a movable ruler is accommodated in the groove. A part of the movable ruler may be brought into contact with the other edge of the substrate by sliding it toward the substrate while being attracted to the magnet.
[0037]
According to the above, since the movable ruler is fixed to the movable base plate by the magnetic force adsorption by the magnet, the movable ruler can be easily attached and detached, and thus the substrate can be easily attached and detached with a pair of rulers. . Note that at least one movable ruler receiving groove is sufficient, but it is more preferable that a plurality of movable ruler receiving grooves are provided at intervals in the left-right direction so as to correspond to several kinds of base materials having different dimensions in the left-right direction.
[0038]
In the above-described case, at least one of the rear end portion of the pair of rulers and the rear edge portion of the movable base plate is engaged with the rear edge portion of the substrate placed on the movable base plate, and the work station is arranged. It is preferable that a stopper capable of preventing the base material from falling off is provided.
[0039]
If the above-mentioned stopper is provided at the rear end of the pair of rulers and / or the rear edge of the movable base plate, the base material can be reliably prevented from falling off the movable base plate at the installation work station. The reliability of the equipment and the safety of work are increased.
[0040]
Note that the means for fixing the base material to the movable base plate is not limited to the one using the pair of rulers as described above, and may be any other appropriate means.
[0041]
In the hot water pipe disposing device according to the present invention, it is preferable that the movable base plate driving means has an inching function capable of intermittently moving the movable base plate upward or downward by an arbitrary distance at the disposing work station. .
[0042]
If the movable base plate drive means has the inching function as described above, the operation of arranging the hot water pipe in the pipe receiving groove of the base material can be performed at a substantially constant height. It is easy and the work efficiency is improved.
[0043]
In the above, the moving distance of the movable base plate may be appropriately determined in consideration of the pattern of the pipe housing groove of the base material so as to facilitate the pipe disposition work, but is usually about 30 to 80 cm. . For setting the moving distance of the movable base plate, a sensor such as a limit switch or a photoelectric tube may be used in addition to using a timer.
[0044]
As the movable base plate driving means, for example, a motor for driving the movable base plate via a power transmission means such as a chain is used. An electric motor is usually adopted as the motor, but an air motor, a hydraulic motor, or the like may be used. The motor may be a geared motor in which a speed reducer, a brake, and the like are integrated, or may be used in combination of these single units. It is preferable that the control unit of the driving means such as a motor is installed at a place where a worker standing on the work table and performing the pipe arranging work can operate. For example, the operation unit is installed on at least one of the two left and right support frames that support the rising straight portions of the left and right rails, preferably both.
[0045]
Moreover, the hot-water pipe arrangement | positioning apparatus by this invention may be further provided with the following pipe feeding apparatuses. That is, the pipe feeding device includes a pipe holding means that can be rotated about a vertical axis and can lay the wound pipe flat, and the pipe fed upward from either one of the inner and outer ends of the wound pipe to the pipe installation location. A pipe guiding means that can guide the pipe, and the pipe guiding means is configured to allow twisting and twisting back of the pipe.
[0046]
In the above-described pipe feeding device, the twisting force generated in the pipe fed from the winding pipe is transmitted to the winding pipe, and the winding pipe is rotated in the direction of returning the twist of the pipe together with the pipe holding means. Therefore, it is possible to supply the pipe to a pipe disposition place, that is, in the vicinity of the disposition work station in a good state without twisting. Moreover, according to the said apparatus, a big force is not required for extension of a pipe, but a pipe can be extended smoothly.
[0047]
The winding pipe may be fed from either one of its inner and outer ends, but preferably from its inner end. If the winding pipe is fed out from the outer end, the pipe to be fed easily comes into contact with the winding pipe, so that a relatively large force may be required for feeding. On the other hand, if the winding pipe is fed out from the inner end, the drawn pipe is less likely to come into contact with the winding pipe, and the feeding can be performed more smoothly.
[0048]
The feeding direction of the winding pipe may be above the winding pipe, but more preferably above the center of the winding pipe. If the winding direction of the winding pipe is above the center, the twisting force generated in the feeding pipe is easily transmitted to the winding pipe, and the rotation of the winding pipe in the direction to untwist the pipe becomes smoother. Become.
[0049]
The winding pipe is preferably rotated around the center of the winding pipe as an axis. However, if the winding pipe is rotated by the twisted force of the drawn pipe, the rotating shaft of the winding pipe is It may be slightly off from the center.
[0050]
The pipe holding means is constituted by, for example, a rotary suspension base that is suspended from a support so as to be rotatable about a vertical axis and that can lay the wound pipe flat.
[0051]
The rotary suspension base is provided with, for example, a rotating member that is rotatably attached to a support body around a vertical axis, and a wound pipe storage box that is suspended from the rotating member via a connecting member.
[0052]
In the case of the above rotating suspension base, since the winding pipe is placed in the winding pipe storage box, there is no possibility that the winding pipe falls during rotation. In order to prevent dust and the like from adhering to the wound pipe, the wound pipe storage box is preferably provided with a top wall that covers the upper side of the wound pipe. When the top wall is provided in the wound pipe storage box, usually, a part or the whole is used as a lid that can be freely opened and closed, and the wound pipe is taken in and out from here. The rotating member is constituted by, for example, a cylindrical or annular rotating body that is rotatably attached to a vertical support body via a bearing. The connecting member is usually composed of a plurality of wires, chains, strings, and the like.
[0053]
In the above, it is preferable that a through-hole through which a pipe drawn out from the winding pipe can be inserted is formed in the central portion of the top wall of the winding pipe storage box.
[0054]
According to the said structure, the delivery direction of a winding pipe can be controlled in a fixed range with the through-hole peripheral part of the top wall of a winding pipe storage box. It is preferable that the peripheral edge of the through hole has a convex circular arc shape with no corners or is bent upward in a circular arc shape so as not to damage the drawn-out pipe. Moreover, you may make it prevent a pipe from getting damaged by attaching soft materials, such as a foam and rubber | gum, to the peripheral part of a through-hole.
[0055]
In the pipe feeding device, the pipe holding means may be a turntable that is provided on a support so as to be rotatable about a vertical axis and on which a wound pipe can be placed flat.
[0056]
A turntable is attached to the upper end part of a vertical support body through a rotation member, for example. The winding pipe may be laid flat on the upper surface of the turntable, but a wrapping pipe storage box similar to the case of the rotation suspension stand is installed on the turntable and is laid flat inside this. You may do it. Moreover, you may make it provide the surrounding wall which prevents dropping of the winding pipe at the time of rotation in the upper-surface periphery part of a turntable.
[0057]
In the above case, the pipe guide means has an inner diameter through which the drawn-out pipe can be inserted, and is opened downward so that the base end portion faces the winding pipe, and the tip end portion faces the pipe installation location. There may be provided a circular pipe-shaped first pipe guiding member that is opened to the outside.
[0058]
According to said 1st pipe guide member, the drawn-out pipe can be smoothly guide | induced to a pipe arrangement | positioning location. In addition, since the first pipe guiding member can be inserted through the drawn-out pipe, the twisting force generated in the pipe in the pipe placement location and the process of being guided there is reliably transmitted to the winding pipe. In addition, the pipe is twisted back by the rotation of the wound pipe without any trouble.
[0059]
The first pipe guiding member may have an appropriate shape and length depending on the positional relationship and distance between the winding pipe and the pipe disposition location, but the twisting force of the drawn pipe is wound. It is preferable not to provide a portion bent at an acute angle or a portion curved at a small radius so that transmission to the turning pipe and twisting back of the pipe by rotation of the winding pipe can be performed without hindrance.
[0060]
The inner diameter of the first pipe guiding member may be any as long as it allows the twist and return of the pipe inserted through the first pipe guiding member, but it is usually about 5 times or more the outer diameter of the pipe.
[0061]
It is preferable that the first pipe guiding member has an arc shape in which at least the inner surface of the tip portion of both end portions spreads outward.
[0062]
According to the said structure, even if the pipe drawn | fed out from the winding pipe contacts the edge part inner surface of a 1st pipe guide member, there is no possibility of being damaged. Further, instead of the above configuration, the end surface of the first pipe guide member is a convex arc shape with no cross section, or a soft material such as foam or rubber is provided on the inner surface of the end portion of the first pipe guide member. Installation may thereby prevent the pipe from being scratched.
[0063]
The first pipe guiding member can be composed of, for example, a synthetic resin tube such as polyethylene or polyvinyl chloride, or a metal tube such as aluminum or stainless steel, but its inner surface is not damaged. It is preferable to use a smooth tube, specifically, for example, a hard tube such as a polyethylene resin tube or a polyvinyl chloride resin tube.
[0064]
In addition to the first pipe guiding member, the pipe guiding means includes a base end portion of the first pipe guiding member and a pipe holding means so that the fed pipe can be guided into the base end portion of the first pipe guiding member. More preferably, a second pipe guide member disposed between them is provided.
[0065]
According to the second pipe guide member described above, the pipe drawn out from the winding pipe can be guided into the base end portion so as not to be damaged by coming into contact with the base end portion of the first pipe guide member. it can.
[0066]
The second pipe guiding member is preferably disposed above the center portion of the wound pipe, so that the winding pipe can be smoothly rotated.
[0067]
The second pipe guide member is composed of, for example, at least two guide rollers provided so as to be rotatable around a horizontal axis so as to surround the drawn pipe, and two guide rollers arranged at intervals in the vertical direction. It has a unit.
[0068]
If the second pipe guide member includes the two guide roller units, the winding pipe can be drawn out more linearly upward. Therefore, the twisting force generated in the drawn-out pipe is easily transmitted to the winding pipe, and the winding pipe rotates more smoothly.
[0069]
Each guide roller unit is usually constituted by four guide rollers on the front, rear, left and right, but may be two or three. In each guide roller unit, the positional relationship of the plurality of guide rollers is such that the drawn-out pipe does not come out from between the guide rollers, but allows twisting and twisting back of the pipe. For example, when there are four guide rollers, the gap between the two guide rollers facing the front and rear and the left and right across the extended pipe is about 1 to 7 mm larger than the outer diameter of the pipe. When each unit is composed of two guide rollers, if the rotation guide surface of each roller has a concave arc shape in cross section so as to be substantially along the outer peripheral surface of the pipe, the drawn-out pipe will not come off the guide roller. can do.
[0070]
Further, a cylindrical body having an inner diameter through which a pipe drawn out from the winding pipe can be inserted may be interposed between the upper and lower guide roller units.
[0071]
