Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid supply nozzle that supplies adhesive or other liquid to a predetermined location.

Conventionally, a synthetic resin liquid supply tube was inserted from a container containing a liquid such as an adhesive, a liquid supply pump was installed in the middle of this tube, and a liquid supply nozzle was installed at the tip to provide a grip. Devices have been developed that supply liquid to predetermined locations.

However, in conventional liquid supply nozzles used in such devices, a tube is semi-fixedly attached to the handle that controls the pump drive switch, so if the liquid used is adhesive, etc. When the adhesive solidifies in the tube of the liquid supply nozzle and the tube needs to be replaced in a relatively short period of time, there is a drawback that it takes a lot of time to replace the tube. .

SUMMARY OF THE INVENTION An object of the present invention is to provide a liquid supply nozzle in which the tube can be easily replaced when the liquid solidifies inside the tube, and the liquid supply operation is easy.

The present invention allows the tube to be easily replaced by detaching the tube holding tube by detachably attaching the liquid supply tube to the groove of the grip main body via the tube holding tube. The liquid supply operation is performed by holding the tube in the tube holding cylinder so that the axis of the tube and the axis of the grip body substantially coincide with each other when the tube is attached to the grip body. The purpose is to facilitate the above-mentioned objectives.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 shows a liquid supply device using a liquid supply nozzle according to the present invention.

In this Figure 1, on the control box 1 are the following:
A liquid container 3 containing a liquid such as an adhesive is placed via a tank holder 2 .

Further, a liquid supply pump 4 whose operation is controlled by the control box 1 is provided on the control box 1, and a synthetic resin liquid supply tube whose one end is inserted into the liquid container 3. It is designed to pass through the inside of the pump 4 in the middle of the tube 5.

For example, this pump 4 has three different timings of operation.
A book rod-like member is provided, and Lu
It consists of a screw pump (also known as a caterpillar pump), etc., which performs the operations of waiting, discharging, suctioning, and securing liquid to discharge and supply a predetermined amount of liquid at a time, and these three rod-like members The tube 5 is inserted so as to come into contact with the tube.

At this time, the material and shape of the tube 5 passing through the pump 4 may be changed depending on the properties of the liquid to be supplied, the viscosity of the discharge amount, etc.

The other end of the liquid supply phase tube 5 is inserted into a tube holding cylinder 6, which serves as a mounting member such as a 1-1 diameter injection needle, and this tube holding cylinder 6 has a substantially cylindrical shape. A tapered fitting portion 8 provided on the central axis of the grip body 7 of
This grip main body 7, which is fitted with a tab, has a push button switch 9, and this push button switch 9 is connected to the controller I/roll box 1 via a cable 10, thereby operating the push button switch 9. As a result, the operating force of the pump 4 is rfly+Iff1ll.

Further, the grip main body 7 includes a cylindrical portion 11, as shown in a cross-sectional view in FIG. 2 and an enlarged right side view in FIG. At the middle left end, a knob 12 as a means for removing the tube is provided at a position that rotates around the middle 1'' axis of the cylindrical portion 11, and is engaged with a screw 13 to remove the tube.

This knob 12 is provided with a through hole 14 in the center portion through which the cable 10 is inserted, and a groove 15 cut to a position deeper than the wall thickness of the cylindrical portion 11.
The tube 5 can be pushed through with a liquid f, i.c., and the knob 12 can be rotated at the same time in the inserted state.

Further, the cylindrical portion 11 also has a slotted groove 16 having approximately the same width as the groove 15.
When the wall thickness of the cylindrical part 11 is completely cut off, the cylindrical part 11
The tube 5 is provided over the entire length of the cylindrical portion 11 so that the tube 5 can be inserted into the cylindrical portion 11.

A switch holding member 18 is fixed to the other end of the cylindrical portion 11, that is, the right end in FIG. The push button switch 9 is held by a switch holding member 18 .

This switch knife holding member 18 has the taper fitting portion 8
A distal end member 19 on the right side is fixed, and these switch holding member 18 and distal end member 19 are also provided with grooves 20 and 21 that are continuous with the slotted groove 16 of the cylindrical portion 11.

The grooves 21 of the tip member 19 are designed to serve as escape parts for the tube 5 when the tube holding cylinder 6 is fitted into the tapered fitting part 8.

In such a configuration, in order to attach the tube holding cylinder 6 to the grip main body 7, the cylinder 6 must be opposed to the tapered fitting part 8 of the grip main body 7, as shown by the chain line in FIG. At the same time, the tube 5 held by the cylindrical body 6 is inserted into the grooves 21 and 20 of the tip member 19 and the switch holding member 18 so that it does not get in the way when the cylindrical body 6 is fitted into the tapered fitting part 8. Keep it.

Next, the cylindrical body 6 is pressed in the direction of the arrow hole in FIG. 20, push it into the slotted groove 16 of the cylindrical part 11 and the groove 15 of the knob 12, and further rotate the knob 12 in the direction of arrow C to shift the position of the groove 15 and the open 1 position of the slotted groove 16. A part of the tube 5 is inserted into the cylindrical part 11 to prevent the tube 5 from being pulled out.

When the attachment of the tube holding cylinder 6 to the grip main body 7 is completed in this way, hold the grip main body 7 in your hand and hold the tube holding cylinder 6.
When the tip of the tube 5 protruding from the tip of the tube 5 is faced to a place where a liquid such as adhesive is needed and the push button switch 9 is pressed in this state, a predetermined amount of liquid is sent out from the liquid container 3 by the action of the pump 4. It will be.

According to this embodiment as described above, the liquid supply tube 5
Since the tube holding cylinder 6 holding the tube is detachable from the grip main body 7, it is easy to replace the tube 5 when the liquid such as adhesive solidifies inside the tube 5 and the tube 5 needs to be replaced. Can be done.

Further, since the tube holding cylinder 6 is fitted to the tapered fitting part 8 on substantially the same axis, it is extremely easy to make the tip of the tube 5 face the area where the liquid is required.

Furthermore, since the tube holding cylinder 6 is composed of a large-diameter injection needle and the tube 5 is inserted into the needle blade, if the tip of the tube 5 deteriorates due to long-term use, the tube By cutting off the deteriorated portion at the tip of the tube 5 and pulling out the tube 5 by the amount that was cut off, the tube 5 can be used again in the same state as the initial state.

Moreover, since the tube 5 is housed in the groove 15, 16, 20, 21, it does not get in the way when operating the liquid supply nozzle and is not damaged.

In carrying out the procedure, the tube holding cylinder 6 as an attachment member is not limited to a syringe needle, but if a commercially available syringe needle is used, it has the advantage of being easy to handle and inexpensive.

Further, the means for preventing the tube 5 from coming off may be gripped by a pinch provided on the grip body 7, but if it is used as in the embodiment described above, there is an advantage that the structure and operation are simple.

Furthermore, there is also a liquid supply pump 4! 1. Pumps of other types may be used in addition to the percussion pump, but when using adhesives etc., it is necessary to consider solidification within the pump, so a tube type screw pump as in the above example is advantageous. It is.

As described above, the present invention has the advantage that it is possible to provide a liquid supply nozzle that allows easy tube replacement and facilitates liquid supply operations.
