Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an applicator for liquid substances such as an adhesive and a sealant, particularly when applying a sealant or the like to a pipe end surface such as a water pipe or a gas pipe. The present invention relates to a liquid material applicator.

[Problems to be Solved by the Invention] Conventionally, an applicator for applying an adhesive, a sealant, or the like to, for example, a threaded surface of a pipe such as a water supply pipe or a gas pipe or other connecting pipe includes (1) An applicator in which, for example, a conical nozzle portion is provided at the mouth of a tube filled with a sealing agent or the like, and an opening is provided at the tip of this nozzle portion to eject the adhesive or sealing agent from the nozzle in the forward direction. (2) The nozzle portion of the above (1) is bent at a tip portion having a discharge hole, or the discharge hole is provided on a side surface of the nozzle portion so as to be lateral or oblique to the longitudinal direction of the nozzle portion. There were applicators for discharging adhesives and sealants.

Then, for example, when applying an adhesive or the like to the thread surface of the pipe using the first applicator, hold the tube so that the discharge hole of the nozzle section is perpendicular to the thread surface, and screw the tube. It was applied so that it was rotated once along the surface. When performing the above-mentioned work using the second applicator, the tube and the pipe are held in parallel, the discharge hole is brought into contact with the screw surface, and the discharge hole is rotated along the screw surface while keeping this state. Was doing.

However, in such an applicator, in order to always orient the discharge hole of the nozzle portion toward the pipe center direction of the pipe, the applicator is constantly held in the middle of the application work or the arm is twisted. Not only is it very cumbersome, but it also increases the work time,
There was a problem that the coating amount was not stable.

Therefore, the applicant of the present invention has proposed an applicator in which the above-mentioned problems are improved in Japanese Patent Laid-Open No. 62-61671, and the present invention is a further improvement thereof. That is, JP-A-62
The invention proposed in -61671 is that the nozzle portion is mounted in a container and rotatably fitted to the coating surface which is circular at the end face of a pipe such as a water pipe.
By rotating the coating nozzle, the coating work can be done smoothly without having to change the coating tool.

However, the present invention is convenient when applying the liquid material to the pipe end surface portion as described above, but when applying the liquid material to other central portions of the planar member, for example, The application was difficult because the ejection port on the spatula portion of the nozzle was oriented in the direction of the central axis of the rotary nozzle, that is, there was no ejection port in the front direction of the spatula portion protruding from the rotary pedestal.
Further, since the rotary nozzle having the discharge port for the liquid material easily rotates, the discharge port at the spatula portion is likely to be displaced with respect to the coating position, which makes accurate coating difficult.
