Description

[Detailed description of the invention] (Industrial application field) This invention involves filling a container with a liquid such as adhesive or sealant, and supplying a pressure fluid such as compressed air or inert gas to attach the container to the bottom of the container. This relates to a liquid supply device that sends out liquid from a nozzle.

(Prior art and its problems) Generally, when supplying a liquid such as an adhesive or a sealant to bond or insulate electrical or mechanical parts, the method shown in Fig. 4 or 5 is used. A liquid supply device as shown is used.

That is, in the case of the liquid supply device shown in FIG. 4, a lid 3 is attached to a container 1 having a flange 1a at the top and a nozzle 2 for delivering liquid at the bottom. It is formed of a lid plate having a claw portion that engages with the flange portion 1a of the container 1 described above, a seal portion that is inserted into the container 1, and a supply tube attachment portion, and
A groove for mounting the O-ring 4 is formed in the above-mentioned seal part, and a liquid supply pipe 5 is provided at the upper center of the supply pipe mounting part, and a liquid supply pipe 5 is provided on the side of the supply pipe mounting part. Compressed air supply pipes 8 are installed at positions intersecting with the liquid supply pipes 5, respectively. A float 6 is movably mounted inside the container 1 and moves up and down as the liquid level changes, and its position is detected by a detector 7 installed on the outer periphery of the container 1. The signal is sent to the control device 11, and the gate valve 9
is opened and closed so that liquid is supplied from the liquid storage tank 10 to the container 1.

In addition, if the amount of liquid sent out from the nozzle is small and once the liquid is supplied to the container, it will not require replenishment for a long time, the lid 3 shown in FIG. A lid 12 with a compressed air supply pipe 8 attached to the attachment part of the liquid supply pipe 5 as shown.
A liquid supply device is used in which a container 1 is equipped with a container 1.

However, with the liquid supply device configured as described above, two types of lids must be prepared depending on the amount of liquid to be supplied, which requires a large amount of cost and requires complicated storage and replacement work. . Furthermore, since the liquid is supplied from the top of the container, there are problems such as air bubbles getting mixed into the liquid and causing variations in the amount of liquid delivered from the nozzle.

(Means for solving the problem) The present invention solves the above-mentioned problems, and can easily handle the problem according to the amount of liquid supplied by simply changing the piping connection using one liquid supply device. This was obtained as a result of studies aimed at providing a liquid supply device that can

That is, the present invention provides a liquid supply device in which a lid is attached to a container that has a flange on the top and a nozzle on the bottom, and that supplies pressurized air into the container to send out liquid from the nozzle. a claw portion that engages with the flange portion of the container, and a seal portion that is inserted into the container;
It is formed by a cover plate having a supply pipe attachment part protruding above the seal part, and a first screw hole is bored in the supply pipe attachment part at a position approximately concentric with the container, and the pressure A supply pipe or a liquid supply pipe is screwed, and a second screw hole is bored at a position intersecting the first screw hole on the side of the supply pipe attachment part, and a compressed air supply pipe, Alternatively, it provides a liquid supply device to which a blind stopper is screwed.

(Example) The configuration of the liquid supply device of the present invention will be explained based on the drawings.

The liquid supply device of the present invention is an improvement on the lid, liquid supply pipe, float, etc. of the liquid supply device shown in FIG. 4 described above, and this point will be explained below.

First, regarding the lid, as shown in FIG. 2, the lid 30 attached to the upper part of the container 1 is
It is formed of a lid plate 30a having a claw portion 3b that engages with the container 1, a seal portion 30c that is inserted into the container 1, and a supply tube attachment portion 30d. A groove for mounting the O-ring 4 is formed in the above-mentioned seal portion 30c. In addition, the supply tube mounting portion 30d has a first screw hole 30e at a substantially central position in the upper part, and a second screw hole 30f at a position intersecting with the first screw hole 30e on the side. .

As shown in FIG. 1, the lid 30 is attached to the flange 1a of the container 1, and a liquid supply tube 50 is inserted into the first screw hole 30e bored in the supply tube attachment section 30d of the lid 30. is screwed on, and the liquid outlet 50a is adjacent to the bottom of the container 1. Further, a compressed air supply pipe 80 is screwed into the second screw hole 30f to supply compressed air from a compressed air supply source (not shown) into the container 1,
A pressing force is applied to the liquid in the container 1 to cause the liquid to be sent out from the nozzle 2. A float 60 is movably attached to the liquid supply pipe 50, and the liquid sent from the liquid supply pipe 50 is supplied below the float 60 and moves up and down as the liquid level changes. The upper and lower positions of the liquid are detected via the float 60, and the signals are sent to the control device 11.

If the amount of liquid sent out from the nozzle is very small, as shown in FIG. Remove the pipe 50 and the compressed air supply pipe 80 screwed into the second screw hole 30f, and insert the compressed air supply pipe 80 into the first screw hole 30e and the blind plug 13 into the second screw hole 30f. to screw on. Then, the lid 30 is removed from the container 1 and the liquid is supplied. At this time, liquid amount detection using the float 60, the detector 7, etc. can be omitted.

(Effects of the invention) As described above, the present invention is a liquid supply system in which a lid is attached to a container that has a flange on the top and a nozzle on the bottom, and pressurized air is supplied into the container to send out the liquid from the nozzle. In the container, the lid plate has a claw portion that engages the lid with the flange of the container, a seal portion that is inserted into the container, and a supply pipe attachment portion that projects above the seal portion. At the same time, a first screw hole is bored at a position substantially concentric with the container of the supply tube attachment section, and a compressed air supply tube or a liquid supply tube is screwed therein. A second screw hole is drilled at a position intersecting the first screw hole on the side of the
Screw on the compressed air supply pipe or blind plug, and
By arranging the liquid outlet of the liquid supply tube screwed into the screw hole of the container adjacent to the bottom of the container, the following effects can be achieved.

(1) Liquid replenishment can be easily changed from automatic to manual by simply changing the screwing position of the supply tube on the lid attached to the container.

(2) Since only one lid is used for one container, there is no need to store or replace lids.
