Description

  The present invention relates to a joining device for synthetic resin piping such as hard vinyl chloride, and more particularly to a joining device capable of efficiently joining a synthetic resin piping having a large diameter and a certain length. The present invention also relates to a method for joining synthetic resin pipes such as hard vinyl chloride, and more particularly to a method for efficiently joining large-diameter and somewhat long synthetic resin pipes using the above apparatus.

  Conventionally, pipes made of synthetic resin such as rigid polyvinyl chloride pipes are widely used as water supply and drainage pipes in various factories. For example, this synthetic resin pipe is formed by applying an adhesive to the outer peripheral surface of one end of a pair of 4 m pipes and inserting and fixing the flange member by human power. A pair of pipes are joined by applying an adhesive to the socket and inserting each other end into a socket (joint) while holding it with a hand held.

  However, in the conventional joint work of rigid polyvinyl chloride piping by an operator, it is inefficient and requires a long time to hold and position the pipe material and insert it perpendicular to the socket opening. Met. In particular, hard vinyl chloride pipes having a large diameter sometimes have a weight of the pipe material exceeding 50 kg, and it is very difficult to perform the joining work by the operator's manual work.

  Furthermore, as described above, when the workability in joining rigid polyvinyl chloride piping is poor, the piping is likely to be displaced with respect to the opening of the socket, and even if it is slightly displaced, a gap is generated in the socket portion, causing water leakage at the joined portion. Therefore, in the above-described operation, there is a problem that the yield of the obtained joint pipe is poor. Since such a problem becomes more apparent as the pipe material becomes heavier, a pipe having a large diameter and a certain length may limit the length of the basic pipe material.

  An object of the present invention is to solve the above-mentioned conventional problems and to provide a synthetic resin pipe joining apparatus capable of efficiently joining a synthetic resin pipe having a large diameter and a certain length. It is another object of the present invention to provide a method for joining synthetic resin pipes that can efficiently join synthetic resin pipes that are large in diameter and long to some extent.

  In order to solve the above problems, first, the present invention is an apparatus for joining two synthetic resin pipes, the first mounting table holding the first synthetic resin pipes, A second mounting table for holding a second synthetic resin pipe provided coaxially with the first mounting table, and a synthetic resin product provided on each of the first mounting table and the second mounting table.

Thus, the flange member can be efficiently and accurately joined to both ends of the synthetic resin pipe.

  In the above inventions (Inventions 1 and 2), it is preferable that a torque sensor is provided in the first and second driving devices (Invention 3).

  When the other end of the first synthetic resin pipe and the second synthetic resin pipe are completely inserted into the socket, the two pipes cannot move any further, and the torque rapidly increases. Therefore, according to the said invention (invention 3), joining of the 1st synthetic resin piping and the 2nd synthetic resin piping can be confirmed by sensing this torque with a torque sensor.

  Next, a method for joining hard vinyl chloride pipes using the hard vinyl chloride pipe joining apparatus of the present embodiment having the above-described configuration will be described.

  First, as shown in FIG. 3, the first rigid polyvinyl chloride pipe A1 is mounted on the pipe clamp tables 8 and 8 of the first mounting tables 6A and 6B, and the pipe clamp table 8 of the second mounting tables 7A and 7B. , 8 is mounted with the second hard vinyl chloride pipe A2. And the 1st hard vinyl chloride piping A1 and the 2nd hard vinyl chloride piping A2 are fixed by spanning the chain C to each pipe clamp stand 8. FIG. In addition, the first flange member F1 is fixed to the first flange face plate fixing member 16, and the second flange member F2 is fixed to the second flange surface plate fixing member 17.

  Then, after the synthetic resin adhesive is applied to the outer peripheral portion of the left end of the first hard polyvinyl chloride pipe A1, the first switch box 13A of the first mounting table 6A is operated and the first control box (not shown) controls the first. The first mounting bases 6A and 6B are moved to the left along the slide rails 4 and 5 by driving the driving members 9A and 9B (arrow 1 in FIG. 3). As a result, the first flange member F1 attached to the first flange face plate fixing member 16 and the left end of the first hard vinyl chloride pipe A1 come into contact with each other, and the first flange member F1 has the first flange member F1 in the first flange member F1. Hard vinyl chloride piping A1 is inserted.

  Subsequently, when the left end of the first rigid polyvinyl chloride pipe A1 comes into contact with the end of the flange member F1, the torque applied to the drive control mechanism increases. Therefore, when the numerical value of the torque sensor (not shown) exceeds a predetermined value, the drive is performed. The control mechanism determines that the joining of the first flange member F1 and the first hard vinyl chloride pipe A1 is completed, and stops the driving of the first drive members 9A and 9B.

  Next, a synthetic resin adhesive is applied to the outer peripheral portion of the right end of the first hard vinyl chloride pipe A1 and the outer peripheral portion of the left end of the second hard vinyl chloride pipe A2, and the right end of the first hard vinyl chloride pipe A1 When the socket S is disposed between the left end of the second rigid polyvinyl chloride pipe A2, the first switch box 13B of the second mounting table 7A is operated, and the second drive member 10A is driven by a drive control mechanism (not shown). , 10B, the second mounting tables 7A, 7B are moved to the left along the slide rails 4, 5 (arrow 2 in FIG. 3). As a result, the right end of the first hard polyvinyl chloride pipe A1 and the left end of the socket S come into contact with each other, and the left end of the second hard vinyl chloride pipe A2 and the right end of the socket S come into contact with each other. The hard vinyl chloride pipe A1 and the second hard vinyl chloride pipe A2 are respectively inserted.

  Subsequently, when the right end of the first hard vinyl chloride pipe A1 and the left end of the second hard vinyl chloride pipe A2 come into contact with the stop portion formed in the middle of the socket S, the torque applied to the drive control mechanism increases. When the numerical value of the torque sensor (not shown) exceeds a predetermined value, the drive control mechanism determines that the joining of the first hard vinyl chloride pipe A1 and the second hard vinyl chloride pipe A2 is completed, and the second drive The driving of the members 10A and 10B is stopped.

  Finally, when a synthetic resin adhesive is applied to the outer periphery of the right end of the second hard vinyl chloride pipe A2, the second flange face plate fixing member 17 is fixed in a state where the second mounting tables 7A and 7B are fixed. 3 and the third drive member 18 is driven by a drive control mechanism (not shown) to move the second flange face plate fixing member 17 leftward along the slide rails 4 and 5.

As a result, the second flange member F2 attached to the second flange face plate fixing member 17 and the right end of the second hard vinyl chloride pipe A2 come into contact with each other, and the second flange member F2 has the second flange member F2. Hard vinyl chloride piping A2 is inserted.

  Subsequently, when the right end of the second rigid polyvinyl chloride pipe A2 comes into contact with the end of the flange member F2, the torque applied to the drive control mechanism increases. Therefore, when the numerical value of a torque sensor (not shown) exceeds a predetermined value, the drive is performed. The control mechanism determines that the joining of the second flange member F2 and the first hard vinyl chloride pipe A2 has been completed, and stops the driving of the third drive member 18.

  In this way, a joined vinyl chloride pipe is manufactured in which the first hard vinyl chloride pipe A1 and the second hard vinyl chloride pipe A2 are joined regardless of human power, and the flange members F1, F2 are attached to both ends. be able to. For example, in the case of the conventional human power, it was possible to manufacture 29 joint pipes per day in 4 work personnel, and about 15 minutes per work time. According to this, only two workers are required, and it is possible to manufacture 52 joining pipes per day in one working time of about 9 minutes, and the working efficiency can be greatly improved.

  In particular, in the present embodiment, the first mounting tables 6A and 6B, the second mounting tables 7A and 7B, and the second flange face plate fixing member 17 move coaxially along the slide rails 4 and 5. Therefore, not only can the first hard vinyl chloride pipe A1 and the second hard vinyl chloride pipe A2 be accurately inserted into the socket S, but also the first flange member F1 and the second flange member F2 can be accurately inserted. Can be attached to. As a result, the rate at which gaps are generated at the joints of the socket S, the flange member F1, and the second flange member F2 is greatly reduced, and it is difficult to cause water leakage at the joint, and the yield of the joint pipe is improved. There is also an effect.

  Further, since the first hard vinyl chloride pipe A1 and the second hard vinyl chloride pipe A2 move mechanically, it is sufficient that the first hard vinyl chloride pipe A1 and the second hard vinyl chloride pipe A2 can be placed on the mounting tables 6A, 6B and 7A, 7B. Therefore, it becomes possible to manufacture a joint pipe longer than the conventional one. For example, in the past, when joining 500mmφ hard vinyl chloride pipes, 8m bonded hard vinyl chloride pipes were manufactured using 4m pipes, but 10m bonded hard vinyl chloride pipes were manufactured using 5m pipes. Therefore, the necessary number of bonded rigid vinyl chloride pipes can be reduced.

  As mentioned above, although this invention has been demonstrated based on the said embodiment, this invention is not limited to the said embodiment, A various deformation | transformation implementation is possible. For example, the synthetic resin piping is not limited to rigid vinyl chloride piping and can be applied to various piping. The timing of applying the adhesive and the order of joining the first hard vinyl chloride pipe A1, the second hard vinyl chloride pipe A2, the first flange member F1, and the second flange member F2 are within the workable range. May be changed as appropriate.
