Description

Piping connection device

The present invention relates to a piping connection device for connecting resin piping members to each other.

Conventionally, a pipe connection device for connecting a pipe member and a pipe member such as a pipe joint to each other is known. In such a pipe connection device, at the time of connection work, first, a pipe member or the like is held on one of two bases that can move with respect to each other along a moving axis, and a pipe joint or the like is held on the other, for example, a pipe joint or the like. And move each opening end so that the central axis of the opening end of one piping member and the central axis of the opening end of the other piping member are aligned in a straight line parallel to the moving axis. Arrange them facing each other. After that, by bringing the two bases closer to each other, the opening end of the other piping member is inserted into the opening end (connection receiving port) of one piping member, and the opening ends of the two piping members are inserted into each other. To connect. In addition, when the open ends of the two piping members are joined to each other, the inner peripheral surface of the open end of one piping member (specifically, the connection receiving port formed inside the connection receiving port) may be melted, or the other piping member may be joined. This is done by an appropriate method such as applying an adhesive to the outer peripheral surface of the end of the opening.

Further, when the open end portion of the pipe member is inserted into the connection receiving port of the open end portion of the pipe joint by using the pipe connection device as described above, the holding of the pipe joint on the base is described in, for example, Patent Document 1. As shown in the above, it is generally performed by sandwiching and tightening the outer circumference of the joint from the left and right in the radial direction by a clamp provided on the base and which can be opened and closed in the horizontal direction perpendicular to the moving axis of the base. Is.

The above-mentioned piping connection device is particularly useful when connecting large piping members to each other. However, it is necessary to arrange the two pipes on the two bases so that the central axis of the opening end of the two pipe members is aligned parallel to the moving axis and in line with each other. For this reason, especially when connecting a pipe member to a pipe joint such as an elbow type or a cheese type, each time the pipe joint is held on the base, the clamp is opened and closed, and the pipe joint is centered in the clamp. (Alignment work), alignment work of the central axis between the opening ends using a spirit level, and level adjustment work in the direction of the central axis are required. Therefore, high skill, labor and time are required for these tasks.

In addition, when a piping member such as a pipe joint is held by a clamp, deformation of the piping member, sliding movement of the piping member in the clamp, and scratches due to the sliding movement occur due to excess or deficiency of the tightening force of the clamp. There is a fear. Furthermore, especially in the case of pipe fittings, the outer diameter and outer peripheral shape differ depending on the manufacturer and material, so tightening the pipe fitting with a clamp requires a certain amount of experience and has to rely on the senses. be.

Therefore, an object of the present invention is to solve the problems existing in the prior art, to secure a certain quality in the pipe connection work regardless of the ability of the operator, and to simplify the work of installing the pipe member on the apparatus. It is an object of the present invention to provide a pipe connection device capable of improving work efficiency and productivity by saving labor and labor.

Further, the central axis of the opening end of the piping member to which the opening end of the pipe member held by the pipe member holding mechanism should be inserted when the piping member is held by the holding adapter is the central axis of the opening end of the pipe member. Since it is arranged in the plane at the same height as the above, the adjustment work of the height position of the piping member becomes unnecessary. Further, since the piping member attached to the holding adapter supported by the support column can be swiveled around the support column, by swiveling the piping member around the support column, the center of the open end of the tube member can be swiveled. The axis and the central axis of the opening end of the piping member into which the opening end of the pipe member should be inserted can be easily aligned. In addition, since the piping member can be held without using a clamp, it is not necessary to open and close the clamp, and it is possible to prevent deformation due to tightening of the clamp and scratches due to slippage in the clamp. Therefore, the work of arranging the piping members at an appropriate position and posture on the base can be simplified and labor-saving, and the work efficiency and productivity can be improved. In addition, the central axis of the opening end of the piping member and the central axis of the piping member can be arranged in a straight line by holding the piping member to the holding adapter and turning the piping member around the support pillar, so it depends on the individual's ability.

There is. In the illustrated embodiment, the pair of clamp mounting bases 35 can be opened and closed by manual operation of the operation handle 39, but the method of opening and closing the pair of clamp mounting bases 35 is not particularly limited. For example, like the pair of clamp mounting bases 27, they may be driven by a driving device or the like so that they can be opened and closed. However, in the pipe connection device 11, it is not essential to provide the clamp mechanism 33 on the second base 19, and only the pipe member holding mechanism 25 may be provided on the second base 19.

The above-mentioned configuration of the pipe member holding mechanism 23 is an example, and in the pipe member holding mechanism 23 and the clamp mechanism 33, the central axis O1 of the open end portion (specifically, the internal flow path thereof) of the pipe member P1 is predetermined. As long as the pipe member P1 can be held so as to extend in parallel with the moving axis M at a position in the height and width direction, the pipe member P1 is not particularly limited, and other configurations can be adopted.

Next, the configuration of the piping member holding mechanism 25 of the first embodiment will be described with reference to FIGS. 3 to 5B.

For example, as shown in FIG. 6, the support pillar 41 is welded to the table surface 19a of the second base 19, or the support pillar is inserted into a screw hole provided in the table surface 19a of the second base 19. Even if the support pillar 41 is erected on the second base 19 by a method such as screwing the 41 or fixing by bolting, the piping member holding mechanism 25 is fixed on the second base 19. good.

The length of the support pillar 41 protruding upward from the base main body portion 47a of the base member 47 is such that the support pillar 41 is fixed to the table surface 19a of the second base 19 and attached to the upper end portion of the fixed support pillar 41. When the pipe member P2 is held in the core 43, the central axis O2 of the other open end of the pipe member P2 (specifically, the connection receiving port 44) is held by the pipe member holding mechanism 23. It is defined so that the central axis O1 of the member P1 is arranged in a horizontal plane extending. When the nut 49 is extrapolated to the support column 41, if the nut 49 is arranged so as to be in contact with the bottom surface of the core core 43, the position of the nut 49 on the support column 41 can be changed. It is also possible to fine-tune the height position of the core core 43 supported by the support pillar 41.

Next, using the pipe connecting device 11 provided with the pipe member holding mechanism 25 according to the first embodiment shown in FIGS. 1 and 2, a 90 ° elbow as the pipe member P2 is used as the pipe member P1. The procedure for connecting a straight pipe will be described.

The pipe member holding mechanism 23 is provided on the table surface 17a of the first base 17 of the pipe connection device 11, and the above-described method is provided on the table surface 19a of the second base 19 of the pipe connection device 11. Therefore, the piping member holding mechanism 25 of the first embodiment is fixed.

First, using the operation handle 21 or the like, as shown in FIG. 1, the first base 17 is separated from the second base 19 in the direction of the moving axis M and moved to the home position. In this state, using the operation handle 31, the pair of clamp mounting bases 27 are separated from each other on the table surface 17a in the width direction perpendicular to the moving axis M, and the pipe member P1 is arranged between the pair of

clamp members

29 and 29. After that, a pair of clamp mounting bases 27 are brought close to each other in the width direction, and a plurality of pairs of clamp members 29, 29 (specifically, two sides sandwiching the apex of the triangular cut portion of each clamp member 29) are connected to the pipe member P1. The pipe member P1 is sandwiched between a plurality of pairs of

clamp members

29, 29 so as to be in contact with the outer peripheral surface of the above in the width direction. Since the notches of each pair of clamp members 29 are provided at the same height, it is shown in FIGS. 1 and 2 that the pipe member P1 is held between the plurality of pairs of

clamp members

29, 29. As described above, the pipe member P1 is arranged so that the central axis O1 of the internal flow path of the pipe member P1 extends in parallel with the moving axis M at a predetermined height. Further, since the pipe member P1 is sandwiched between each pair of

clamp members

29, 29 attached to the clamp mounting base 27 that opens and closes in the width direction, the central axis O1 of the pipe member P1 is predetermined in the width direction. The tube member P1 is arranged so as to extend to the position.

On the other hand, on the table surface 19a of the second base 19, the piping member extends in the direction of the central axis O3 orthogonal to the central axis O1 of the internal flow path of the pipe member P1 held by the pipe member holding mechanism 23. The support pillar 41 of the holding mechanism 25 is erected. That is, when the pipe member P1 is held by the pipe member holding mechanism 23, the central axis O1 of the internal flow path of the pipe member P1 is arranged so as to be aligned with the central axis O3 of the support pillar 41 in the moving axis M direction. To. Further, a core core 43 as a holding adapter supported at the upper end of the support column 41 so as to be coaxial with the support column 41 is previously connected to the connection receiving port 44 at one opening end of the 90 ° elbow which is the piping member P2. When the pipe member P2 is held in the core core 43 by inserting it to a predetermined depth, the central axis O2 of the other open end portion (specifically, the connection receiving port 44 thereof) of the pipe member P2 is displaced by the pipe member holding mechanism 23. The piping member P2 is arranged so as to extend in a horizontal plane at the same height as the central axis O1 of the pipe member P1 to be held (specifically, its internal flow path). Therefore, if the pipe connection device 11 is used, the central axis O2 of the opening end of the pipe member P2 to be connected to the pipe member P1 is at the same height as the central axis O1 of the pipe member P1 held by the pipe member holding mechanism 23. It is not necessary to adjust the height positions of the pipe member P1 and the pipe member P2 so that they can be arranged.

Further, the central axis O3 of the support pillar 41 extends so as to be orthogonal to the central axis O1 of the internal flow path of the pipe member P1 held by the pipe member holding mechanism 23, and the core core 43 is coaxial with the support pillar 41. It is supported by the support pillar 41 so as to be. Therefore, with the core core 43 inserted into the connection receiving port 44 at one open end of the piping member P2, simply rotating the piping member P2 around the central axis of the core core 43 is sufficient to rotate the piping member P2 to the other of the piping members P2. The piping member 2 is arranged so that the central axis O2 of the opening end portion (specifically, the connection receiving port 44 thereof) is aligned with the central axis O1 of the pipe member P1 held by the pipe member holding mechanism 23. Can be done. The rotation of the piping member P2 around the central axis of the core core 43 may be performed by sliding the piping member P2 with respect to the core core 43, and the core core 43 holding the piping member P2 is supported around the central axis O3. This may be done by rotating the column 41.

Further, as shown in FIG. 13, another pipe as a pipe member P2 is connected to the other open end of the pipe member P1 to which the pipe joint P5 such as an elbow is already connected to one open end. When connecting a joint, the center of the open end of the pipe joint P5 connected to one of the open ends of the pipe member P1 on the opposite side of the pipe member P1 (hereinafter referred to as the outer open end). Direction of the central axis of the opening end portion (hereinafter, referred to as the outer opening end portion) opposite to the pipe member P1 in the piping member P2 connected to the other opening end portion of the pipe member P1 with respect to the axis line O4. (In FIG. 13, it is specified that the outer open end of each pipe joint faces the opposite side in the vertical direction and the central axis of the open end extends in the vertical direction). In such a case, in the pipe connecting device that holds the pipe member P2 by using a clamp, the central axis O2 of the opening end of the pipe member P1 connected to the pipe member P1 and the central axis O1 of the pipe member P1 are aligned. Not only aligning, but also adjusting the direction of the outer open end of the pipe joint as the pipe member P2 and the direction of the outer open end of the pipe joint P5 already connected to the pipe member P1 to make the pipe member P2 into the clamp. Had to hold. However, in the pipe connection device 11, if the pipe member P2 is held in the core core 43, the central axis O2 of the open end portion (specifically, the connection receiving port 44) of the pipe member P2 on the side connected to the pipe member P1. Not only extends in the horizontal plane at the same height as the central axis O1 of the pipe member P1 (specifically, its internal flow path) held by the pipe member holding mechanism 23, but also extends at the outer open end of the pipe member P2. The piping member P2 is arranged so that the central axis is aligned with the central axis O3 of the support column 41, and the direction of the central axis at the outer opening end of the piping member P2 is fixed. Therefore, if the central axis O4 of the outer opening end of the pipe joint P5 already connected to the pipe member P1 adjusts the direction of the outer open end of the pipe joint connected to the pipe member P1 with respect to the central axis O3 of the support column 41. Well, the adjustment work can be greatly simplified and the work time can be shortened. In the case as shown in FIG. 13, a level is applied to the opening of the outer opening end of the pipe joint P5 connected to the pipe member P1 so that the opening surface extends horizontally. The orientation may be adjusted and the pipe member P1 may be held by the pipe member holding mechanism 23.

Next, the piping member so that the central axis O2 of the connection receiving port 44 at the opening end of the piping member P2 is substantially aligned with the central axis O1 of the internal flow path of the pipe member P1 held by the pipe member holding mechanism 23. After arranging P2, the first base 17 is brought closer to the second base 19 by operating the operation handle 21 or the like. The central axis O2 of the other open end of the pipe member P2 held by the pipe member holding mechanism 25 (specifically, the connection receiving port 44 thereof) is the internal flow path of the pipe member P1 held by the pipe member holding mechanism 23. Since it is arranged so as to be substantially aligned with the central axis O1, when the first base 17 is brought closer to the second base 19, the inside of the connection receiving port 44 at the open end of the piping member P2 The open end of the pipe member P1 is inserted into the pipe member P1, and the open end of the pipe member P1 and the open end of the pipe member P2 are connected to each other. The joint between the pipe member P1 and the piping member P2 is, for example, the outer peripheral surface of the opening end of the pipe member P1 to be inserted into the connection receiving port 44 of the opening end of the piping member P2 or the connection receiving port of the opening end of the piping member P2. This is done by applying an adhesive to the inner peripheral surface of 44 or by heating and melting them. Since the piping member P2 can be rotated around the central axis of the core core 43 (that is, around the central axis O3 of the support pillar 41), the open end of the piping member P2 into which the pipe member P1 should be inserted is oriented in any direction. It is possible to perform adhesive application work and melting work. Therefore, the coating work and the melting work can be smoothly performed, and the working time can be shortened.

Further, when the first base 17 and the second base 19 are brought close to each other, the open end of the pipe member P2 into which the open end of the pipe member P1 should be inserted (specifically, the connection receiving port 44 thereof). Even if the central axis O2 of the above is not exactly aligned with the central axis O1 of the internal flow path of the pipe member P1 held by the pipe member holding mechanism 23, it is easy to deal with it. If the piping member P2 is rotated around the central axis of the core core 43 while the pipe member P1 and the piping member P2 are brought close to each other to finely adjust the direction of the opening end of the piping member P2, the opening end of the pipe member P1 can be finely adjusted. The central axis O1 of the portion (specifically, its internal flow path) and the central axis O2 of the open end portion (specifically, its connection receiving port 44) of the piping member P2 can be easily aligned in a straight line. Therefore, the work of adjusting the piping member P2 to a predetermined orientation and posture can be easily performed without relying on the experience of the operator or the like.

Further, the piping member P2 can be held by the piping member holding mechanism 25 simply by inserting the core core 43 into the connection receiving port 44 at the opening end thereof, and the clamp member hits the outer peripheral surface of the piping member P2. It is not necessary to hold the piping member P2 between the clamp members in contact with each other. Therefore, it is possible to prevent deformation, scratches, and the like of the piping member P2 due to tightening by the clamp member. Further, when the piping member P2 is held by being sandwiched by the clamp member, in order to replace the piping member P2 with the next piping member P2 after the connection work is completed, the opening / closing work of the clamp mounting base 35 and the piping sandwiched by the clamp member are performed. It is necessary to perform the alignment work of the member P2. On the other hand, in the pipe connection device 11, even when the pipe member is replaced with the next pipe member P2, the pipe member holding mechanism is simply inserted into the connection receiving port 44 at the opening end of the next pipe member P2. The next piping member P2 can be held in 25, and height alignment is completed. Therefore, the connection work can be simplified and the work efficiency and productivity can be significantly improved.

When connecting the pipe member P1 to the pipe member P2 of different types and dimensions, for example, from the elbow having a large opening diameter as shown in FIG. 7A to the elbow having a small opening diameter shown in FIG. 7B. Even when the dimensions of the piping member P2 to which the member P1 is inserted are changed, as can be seen from FIGS. 7A and 7B, only the core core 43 supported by the support pillar 41 can be replaced. .. Specifically, the bolt 45 penetrating the through hole 43b of the core core 43 is removed from the upper end of the support pillar 41, and the core core 43 supported by the support pillar 41 is replaced with another core core 43 and then replaced. By simply screwing the bolt 45 that has penetrated through the through hole 43b of the core core 43 into the female screw hole 41a at the upper end of the support column 41, the replacement work of the core core 43 is completed, and piping of different types and dimensions is completed. It can be made to correspond to the member P2. Further, the operator does not need to consider changing the position of the arrangement of the piping member P2 due to the change in the type and size of the piping member P2, and the core core 43 is connected to the inside of the connection receiving port 44 at the opening end of the piping member P2. The different piping members P2 can be held in a predetermined position and posture simply by inserting them into the pipe, which facilitates correspondence. Therefore, it is possible to connect the pipe member P2 and the pipe member P1 with high quality.

Next, the piping member holding mechanism 55 according to the second embodiment will be described with reference to FIGS. 8 to 11. The first embodiment of the piping member holding mechanism 55 according to the second embodiment is that a substantially plate-shaped adapter body 57 is used instead of the core core 43 as the holding adapter supported by the support pillar 41. It is mainly different from the piping member holding mechanism 25 depending on the form. The point that the support pillar 41 is erected on the table surface 19a of the second base 19 is the same as that of the piping member holding mechanism 25 according to the first embodiment. Therefore, here, the support pillar 41 is used as the table surface. The description of the configuration for standing in 19a will be omitted.

The piping member holding mechanism 55 according to the second embodiment extends on the table surface 19a so as to extend along the central axis O3 perpendicular to the central axis O1 of the internal flow path of the pipe member P1 held by the pipe member holding mechanism 23.

Similar to the piping member holding mechanism 25, the support pillar 41 shown in the figure has a base member 47 attached to the lower end of the support pillar 41, which is sandwiched by a pair of clamp mounting bases 35 to form a second base 19. It is fixed to the table surface 19a. However, as in the case of the piping member holding mechanism 25, the fixing of the support pillar 41 to the table surface 19a of the second base 19 is not particularly limited, and the table surface 19a of the second base 19 is not particularly limited. The support pillar 41 may be fixed by welding.

A through hole 57c for penetrating is formed. By installing the positioning member 61 inserted into the positioning hole 41c of the support column 41 so as to abut against the bottom surface of the lower leg portion, the adapter body 57 rotates at a predetermined height position of the support column 41. Supported as possible. However, as long as the adapter body 57 can be supported at a predetermined height position of the support column 41, the configuration of the mounting portion 57b and the configuration of the positioning member 61 are not limited. For example, a rectangular parallelepiped-shaped portion that is connected so as to project from the back surface of the flat plate portion 57a and has a through hole 57c for penetrating the support pillar 41 can be used as the mounting portion 57b. Further, the support pillar 41 may be provided with a plurality of positioning holes 41c along the central axis O3 so that the height position of the adapter body 57 supported by the support pillar 41 can be changed in a plurality of steps. A predetermined height of the support column 41 is provided by providing a male threaded portion 41b on the outer peripheral surface of the support column 41 and screwing a nut 49 into the male threaded portion 41b of the support column 41 to bring it into contact with the bottom surface of the mounting portion 57b. The adapter body 57 may be supported at the position. In this case, the height position of the adapter body 57 supported by the support pillar 41 can be continuously changed. Further, an upper end portion of the support column 41 is provided with a contact plate extending upward from the back surface of the flat plate portion 57a so as to project beyond the through hole 57c and penetrate the through hole 57c of the mounting portion 57b. It is also possible to support the adapter body 57 at a predetermined height position of the support pillar 41 by abutting the adapter body 57 on the contact plate.

As shown in FIG. 10, the adapter body 57 is used when holding a piping member P3 with a flange 63 such as a pipe joint. As shown in FIG. 9, the flat plate portion 57a of the adapter body 57 is provided with a plurality of flange fixing holes 65 which are screw holes.

In the adapter body 57, the pipe member P1 in which the central axis O2 of the opening end portion (specifically, the connection receiving port 58 thereof) of the piping member P3 into which the opening end portion of the pipe member P1 is to be inserted is held by the pipe member holding mechanism 23. Extends in a horizontal plane at the same height as the central axis O1 of the open end portion (specifically, its internal flow path), and the central axis O2 of the open end portion of the piping member P3 is orthogonal to the central axis O3 of the support column 41. As described above, the piping member P2 is held in the flat plate portion 57a. Further, the support pillar 41 is arranged so that its central axis O3 is orthogonal to the central axis O1 of the internal flow path of the pipe member P1 held by the pipe member holding mechanism 23, and the pipe member holding of the first embodiment. Similar to the case of the core core 43 of the mechanism 25, the adapter body 57 is also rotatably supported around the central axis O3 of the support pillar 41. Therefore, by rotating the adapter body 57 around the central axis O3 of the support column 41, the central axis O1 of the open end portion (specifically, the internal flow path thereof) of the pipe member P1 held by the pipe member holding mechanism 23. And the central axis O2 of the open end portion (specifically, the connection receiving port 58) of the piping member P2 held by the piping member holding mechanism 55 can be aligned so that the piping member P2 is arranged. It is possible.

A core core 81 is attached to the tip of the auxiliary pillar 73 coaxially with the auxiliary pillar 73 by a bolt 79 or the like. The core core 81 can hold a socket type piping member P4 into which the opening ends of the other tube members P1 can be inserted into the two opening ends. That is, the core core 81 has an outer shape of a rotating body that is complementary to the connection receiving port 80 at one open end of the socket type piping member P4. Further, the auxiliary pillar 73 and the core core 81 connect the core core 81 attached to the tip of the auxiliary pillar 73 fixed to the flat plate portion 57a of the adapter body 57 to one open end of the piping member P4. When the piping member P4 is held in the core 81 by being inserted into the receiving port 80, the central axis O2 of the other open end of the piping member P4 (specifically, the connection receiving port 80) is the pipe member holding mechanism 23. The central axis O2 at the opening end of the pipe member P4 extends in the horizontal plane at the same height as the central axis O1 of the internal flow path of the pipe member P1 held by the pipe member P1 so as to be orthogonal to the central axis O3 of the support pillar 41. It is configured to be placed. The support pillar 41 is arranged so that its central axis O3 is orthogonal to the central axis O1 of the internal flow path of the pipe member P1 held by the pipe member holding mechanism 23 (that is, the support pillar 41 and the pipe member holding mechanism 23). The central axis O1 of the pipe member P1 held by the pipe member P1 is aligned in the width direction), and the adapter body 57 is also a support column as in the case of the core core 43 of the pipe member holding mechanism 25 of the first embodiment. It is rotatably supported around the central axis O3 of 41. Therefore, by rotating the adapter body 57 around the central axis O3 of the support column 41, the adapter body 57 is held by the central axis O1 of the internal flow path of the pipe member P1 held by the pipe member holding mechanism 23 and the pipe member holding mechanism 55. The piping member P4 can be arranged so that the central axis O2 of the opening end portion (specifically, the connection receiving port 80 thereof) of the piping member P4 extends in a straight line. The central axis O1 of the pipe member P1 held by the pipe member holding mechanism 23 and the central axis O2 of the opening end of the pipe member P4 held by the pipe member holding mechanism 55 are aligned in a straight line. When the base 17 of 1 is brought close to the second base 19, the open end of the pipe member P1 is inserted into the connection receiving port 80 of the open end of the pipe member P4 to form the pipe member P4 and the pipe member P1. Can be connected.

In the illustrated embodiment, the auxiliary pillar 73 is fixed to the flat plate portion 57a of the adapter body 57 by the bolt 77. However, the method of fixing the auxiliary pillar 73 to the flat plate portion 57a of the adapter body 57 is not particularly limited. For example, the auxiliary pillar 73 may be integrally formed by welding to the flat plate portion 57a, and the auxiliary pillar 73 may be configured as a part of the adapter body 57.
