As long as it is present, each of the injection nozzles 6 forms an injection flow 17 that is injected from the injection nozzle 6 while being directed in the radial direction of the injection shaft 7. Then, by the rotation of the injection shaft 7 controlled to synchronize with the conveying operation, each injection flow 17 moves in accordance with the container 3 passing through each injection station 1, 2 as is well known to those skilled in the art.

  A special feature of the injection equipment 5 or its injection nozzle is that the head part 14 is preferably detachably fixed by sliding it and possibly by adhering and / or locking to the injection nozzle body part 10. In the point. Here, the slide of each head portion 14 is performed in the longitudinal axis direction of the ejection shaft 7, that is, the Z-axis direction. Further, each head portion 14 is installed or sandwiched on the ejection shaft 7 on the side of each ejection nozzle main body 10 together with the recess 14.1 in the head portion 14 by slight elastic deformation at the time of mounting. Then, each head part 14 is displaced to an axial direction, and is finally fitted by the upper part 10.1 in the injection nozzle main-body part 10. FIG.

  For this reason, the head portion 14 faces the X-axis direction in the attached state, and protrudes from the outer surface of the head portion 14. Two edge portions having other protrusions 19 provided downward and shifted in the Y-axis direction with the head portion 14 attached are provided. Here, the protruding portion 19 protrudes from the outer surface of the head portion 14 on the opposite side to the recessed portion 14.1 like the protruding portion 18.

It is formed to be concavely curved around an axis parallel to the Z axis. Therefore, a special member (such as a screw) for fixing the injection nozzle body 10 to the liquid pipe / support pipe 9 is not required. Further, for example, it is not necessary to provide the liquid pipe / support pipe 9 with a horizontal plane for fixing the injection nozzle 6 or the injection nozzle body 10.

  In the illustrated embodiment, the seal member 21 can be formed as an elastic seal member formed of the seal member 12. Thereby, the attachment of each injection nozzle main-body part 10 can be facilitated.

<Embodiment 2>
In FIGS. 8 to 10, as a second embodiment of the present invention, an injection nozzle 6 a is illustrated instead of the injection nozzle 6 in the injection stations 1 and 2, and the injection nozzle 6 a together with the injection shaft 7 is illustrated. It is used to form each injection facility 5.

  Also in the present embodiment, the injection nozzle 6 a is configured by the injection nozzle main body 10 a corresponding to the injection nozzle main body 10 and the head portion 14 a corresponding to the head portion 14. Here, in the same manner as the fixing of the head part 14 described above, the head part 14a has a protruding part 19 formed on the head part 14a at the upper part of the injection nozzle body part 10a by locking or sliding to the side. By engaging with the recess 20, it is fixed to the upper part of the injection nozzle body 10a. The fixing of the head portion 14a to the spray nozzle body portion 10a can be further ensured by bonding.

  Further, the injection nozzle 6a is not fixed to the liquid pipe / support pipe 9 by the engagement of the latch 22, but the liquid pipe / support pipe 9 is formed into a pipe clamp shape or an arcuate shape. It differs from the jet nozzle 6 only in that the jet nozzle 6a is fixed to the liquid pipe / support pipe 9 by the surrounding pipe clamp 23. The piping clamp 23 is a molded member made of a suitable material (preferably elastic material) made of, for example, a synthetic resin (preferably a synthetic resin having elasticity), and includes two arm portions 23.1 and the arm. It comprises an arcuate part 23.2 connected to part 23.1.

  Further, both free ends of the piping clamp 23 are provided with arm portions 23.1 having protrusions 24 directed inward, that is, in the spatial direction between the two arm portions 23.1. Yes. Each projection 24 is formed in a claw shape or with an inclined surface on the lower side facing the arcuate portion 23.2. This inclined surface is connected to the inner surface of the arm portion 23.1 having the protrusion 24 at an angle smaller than 90 °.

  By the way, in the piping clamp 23 fixed to the injection nozzle body 10a, each projection 24 is engaged with and accommodated in the recess 25, and each arm 23.1 is directly connected to the projection 24 on its inner surface. Concave portions 25 that engage with the projections 24 are formed on the two opposing sides of the injection nozzle main body 10a so as to contact the portions in a plane. Furthermore, the inner surface of the arm part 23.1 and the lower part 10a. Of the injection nozzle body which is curved in a cylindrical shape and faces the opposite side of the head part 14a. A cylindrical opening 27 is formed with the inner surface of the arcuate part 23.2 having 1. The opening 27 accommodates the liquid and supporting pipe 9 together with the attached injection nozzle 6 a under the elastic deformation of the pipe clamp 23.

  A locking member 28 protruding from the lower part is provided at the lower portion of the ejection nozzle body 10a opposite to the head portion 14a. The locking member 28 is a liquid like the latch 22 in the ejection nozzle 6. Disposed around the opening of the passage 11. Further, since the locking member 28 penetrates the seal member 21 similarly to the above-described latch 22, the locking member 28 protrudes from the opposite side of the injection nozzle main body portion 10 a in the seal member 21. In the illustrated embodiment, a total of four locking members that form a virtual rectangular corner portion are provided.

  Each injection nozzle 6a is attached at each connection opening 9.1 for the injection nozzle 6a in the liquid pipe / support pipe 9. Here, the connection opening 9.1 has a non-circular rectangular cross section as shown in FIG. 12, for example, and the locking member 28 is inserted into the connection opening 9.1. It has become. Therefore, the locking member 28 is supported at each edge of the connection opening 9.1, and each injection nozzle body 10a is accurately positioned and guided with respect to the liquid pipe / support pipe 9. In addition, it can be supported by the liquid pipe / support pipe 9 so as to be rotatable.

  Specifically, each of the injection nozzles 6a is attached to the liquid pipe / supporting pipe 9 with an appropriate injection nozzle main body 10a assembled in advance by the functional member of the injection nozzle main body 10a and the seal member 21. This is done by installing in the connection opening 9.1 in the liquid and supporting pipe 9. Therefore, the locking member 28 engages with the connection opening 9.1, and the injection nozzle body lower part 10a. 1 contacts the pipe 9 for liquid and support together with the seal member 21.

  Subsequently, the piping clamp 23 surrounds the liquid piping / supporting piping 9 by sliding the projection 24 to the side in the direction of the recess 25 and under elastic deformation or tension of the piping clamp 23. Attached to. At this time, the pipe clamp 23 is sealed in such a manner that the liquid pipe / support pipe 9 and the liquid passage 11 formed in the injection nozzle body 10a or the intermediate nozzle 13 are sealed. The injection nozzle body 10a is connected to the injection nozzle body lower part 10a. 1 is elastically pressed against the liquid pipe / support pipe 9 together with the seal member 21 provided in the pipe 1.

  By the way, when the projection 24 is slid sideways in the direction of the recess 25 and engaged, the piping clamp 23 is attached to the arcuate portion 23.2 so that the piping clamp 23 can be attached and tensioned. The width is narrow. And this narrow part is 23.4 in FIG. 9 in the axial direction (Z direction in the attached state) of the opening part 27, and from the side in the piping clamp 23 shown by 23.3 in FIG. The width is reduced toward the side surface indicated by.

  Thereby, at the time of attachment of each piping clamp 23, in the injection nozzle main body part 10a already arrange | positioned at the piping for liquid piping and supporting piping 9, both protrusion part 24 is recessed part 25 with the edge part adjacent to the said side surface 23.3. Can be inserted. In this insertion, the pipe clamp 23 is inclined with respect to the liquid pipe / support pipe 9 or the Z axis, that is, the liquid pipe / support pipe 9 or the center axis of the opening 27. This is possible in a state of being inclined with respect to the Z axis.

  Subsequently, the piping clamp 23 is completely pushed into the injection nozzle body 10a under increasing flat portions and tension. That is, the protrusion 24 is inserted into the recess 25 under increasing flat portions and tension in the pipe clamp 23, and finally the injection nozzle body 10 a is a liquid having the tensioned pipe clamp 23. It will be fixed to the piping for supporting and supporting 9.

  In this embodiment, after mounting the entire injection nozzle body 10a, the head 14a is fitted into the injection nozzle body 10a by pushing the head 14a in the longitudinal direction of the injection shaft 7 (Z-axis direction). The injection shaft 7 is attached by installing the upper portion of the injection nozzle body 10 a on the injection shaft 7.

  The jet installation 5 or its jet nozzle 6 or 6a is preferably characterized by sliding the head part 14 or 14a and possibly by being glued and / or engaged with the jet nozzle body part 10 or 10a. The point is that it is detachably fixed. The fixing of the head part 14 or 14a with the injection nozzle body part 10 or 10a as described above not only facilitates the assembly of the injection equipment 5, but also allows the head part 14 or 14a to be replaced quickly, easily and without inconvenience. Is possible.

  Further, when it is necessary to replace the intermediate nozzle 13 for repair and / or maintenance, the injection shaft 7 is removed from or separated from the injection nozzle body 10 or 10a by easy removal of the head portion 14 or 14a. It is possible. Maintainability of the injection facility 5 is improved by detachably fixing the head portion 14 or 14a.

  By the way, if the injection nozzle body 10 or 10a is injection-molded based on an appropriate synthetic resin, appropriate seal members such as the seal members 12 and 21 are simultaneously prepared at the time of manufacturing each injection nozzle body 10 or 10a. Is possible. That is, the sealing member is put in an injection molding machine, or each injection nozzle body 10 or 10a and the corresponding sealing member are manufactured by sandwich molding.

  In addition to the advantages as described above, the injection facility 5 can avoid the formation of a horizontal surface, a concave portion, or an inclined portion where the liquid concentrates, regardless of whether the injection nozzle 6 or 6a is used. That is, a flat part for fixing the head part 14 or 14a in each injection nozzle main body part 10 or 10a and a flat part for fixing the injection nozzle main part 10 or 10a in the liquid pipe / supporting pipe 9 are unnecessary. Therefore, formation of a horizontal plane, a concave portion or an inclined portion can be avoided. In particular, the liquid pipe / support pipe 9 preferably has a circular cross-sectional shape.

  Although the present invention has been described with the above embodiments, numerous modifications and variations are possible without departing from the scope of the present invention. For example, it is conceivable to form the injection nozzle body 10 or 10a integrally with the head 14 or 14a. The attachment of the injection nozzle 6 formed by integrally forming the injection nozzle 10 and the head portion 14 may be performed by, for example, sliding the injection nozzle 6 with respect to the injection shaft 7. Further, the mounting of the spray nozzle 6 constituted by integrally forming the spray nozzle 10 and the head portion 14 to the liquid piping / supporting piping 9 uses the sealing material forming the sealing members 12 and 21 again. This is done by engaging the latch 22 with the connection opening 9.1. However, according to such a configuration, there is a drawback in that it is necessary to disassemble the injection nozzle 6 formed by integrally forming the injection nozzle 10 and the head portion 14 when the injection shaft 7 is removed.

  When the injection nozzle 6a is used, the pipe clamp 23 is removed from the liquid pipe / support pipe 9 unless the connection of the pipe clamps 23 to the injection nozzle body 10a is strengthened by bonding. However, the injection nozzle 6a is not destroyed.
