Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a tube holding device used for applying a coating material such as an adhesive, a chemical solution, or a stimulant to the surface of an object.

Prior Art Conventionally, in order to apply adhesive to the surface of an object, for example in an automatic adhesive machine, a tube made of Teflon or the like with an outer diameter of about 1 mm is held in a holding member, and the adhesive poured into the tube is held by a holding member. It was delivered from the tip of the tube and applied to the surface of the object. In that case, the height of the holding member relative to the object is set mechanically, but an appropriate gap is required between the tube tip and the object surface, and this gap must be finely adjusted. Sometimes it doesn't happen. By the way, conventionally, in order to have the tube held by the holding member, the holding member is
It is common to split the holding member into two parts, form a groove on each opposing surface for holding the tube, place the tube there, and then integrally connect the two parts of the holding member with screws. However, with this, it is necessary to loosen the screw and then tighten it at the 1q section between the two gaps.Furthermore, if multiple tubes are held by the holding member at the same time, the gap between the above When the screw is loosened to change the amount of protrusion of the tip of one of the tubes from the holding member for adjustment, the other tubes are also untightened, causing their settings to become erroneous, and making adjustments time consuming. There were such drawbacks. Separately, a syringe needle is attached to the tip of the tube, and the syringe needle is inserted into the small hole formed in the holding member instead of the tube to make it into the vocal tract, and the syringe needle is inserted into and out of the small hole using a screw. Another method is to adjust the gap between the tip of the injection needle and the surface of the object by loosening the screw as necessary. - If you have to clean a single piece of wood, the glue will solidify in the hole and make the scale unusable, or if you are using multiple tubes at the same time, loosen each screw and then Without tightening, it is impossible to adjust the distance between the tip of the injection needle and the surface of the object, and the adjustment work is not efficient. Also, the mounting pinch cannot be too close due to the size of the tightening screw.

Purpose This invention allows the amount of protrusion of the tube from the holding member to be changed very easily, thereby making it easy to adjust the circumference of the gap between the tip of the tube and the surface of the body to which the coating material is to be applied. The object of the present invention is to provide a tube holding device that has the following features.

Summary The thin tube holding device of the present invention is characterized in that a tube is press-fitted into a through-hole of an elastic member that is pushed into and held in a multiple attachment hole of a holding member.

EXAMPLE Next, an example in which the present invention is applied to a tube holding device in an automatic bonding machine will be described with reference to the accompanying drawings.

First, in Figure 1 (Al (B+ is one tube (al
) is held by the holding member (bl), and the holding member (b) is formed with a through-mounting hole (bl), into which the elastic member (C1) is press-fitted. A through hole is also formed in this elastic portion 1' (Ct), into which the tube (al) is press-fitted, and its tip protrudes downward from the holding member tb+.

Here, the tube (a,) is made of Teflon or Hynyl and has an outer diameter of 1.2 mmφ and an inner diameter of 0.6 mmφ.

The elastic member (C1) is made of silicone rubber, has an outer diameter of 3.0 mm, and an inner diameter (diameter of the through hole) of 1.0 mm, which is slightly smaller than the outer diameter of the tube (al).

Furthermore, the diameter of the hole (bl) of the holding member (b) is slightly smaller than the outer diameter of the elastic member (C1), and is 2.8 mtnφ~
It is approximately 2.9 m+nφ.

Now, when applying adhesive + e) to the surface of object td),
Set the height of the holding member (b) from the object (d) by moving it up and down to the east using an air cylinder or the like, or set the height of the holding member (b) from the object (d). At this time, a gap T1 is formed between the tube (al) and the object (d).H is the gap between the tip of the tube (al) and the surface of the object (d), approximately 0.5 mm to 0.0 mm. There is a suitable value, and within that range, the #adhesive (e+) is adjusted to the optimal value according to the sex.To perform this adjustment, simply insert the tube (al) into the elastic member (C1). It is good that the number is 1!0, and the tube (al) is the elastic part U'
Since the tube (Ct) is simply press-fitted into the communicating hole, this work can be done easily, and the tube (al) is held as it is in the holding member +b+ via the elastic member (C1). be done. Therefore, the adjustment work is extremely simple.

No. 11g1 (Ct is the basic embodiment described above.
), and elastic members (C1) (C2) are attached to them.
(C3) and (C4) are press-fitted, respectively. In addition, tubes (aJ) (
a2), (a3), and (a4) are press-fitted, respectively. In this application, for example, when adjusting the amount of protrusion of the tube (al) from the holding member (bl), other tubes (
a2), (33), and (a4) are not affected or affected in any way, and the amount of protrusion of all tubes from the holding member fb) can be adjusted individually, making adjustment easy. , and it doesn't take much time.

The elastic members (C1) (C2) (C3) (C4) have large diameter portions (bl 1) (b2-IXb3-IXb4-

Even if they are not press-fitted into the large diameter part of the It is sufficient to roughly inspect the diameter.

FIG. 2(C) shows a modification of the 21st YI (A) fB+ embodiment.

This modification is based on the lower surface of the holding member tb+, that is, the small diameter portion (bl-2Xb2-2Xb3-2) (b4
-2) is formed as shown in the figure, and both PFs (b5Xb6) of that surface are used as contact surfaces for IJp and body fd), and the tube ("IXa2Xa3Xa4)
is made to protrude into the recess to provide a gap between it and the object (d). The buds of the holding member (b) are formed in the direction in which the tubes (al) (32Xa3Xa4) are arranged, and reach the side walls on both sides of the holding part t't (+)), and the number of tubes is If the gap is small, the gap between the tip of each tube and the object (dl) can be directly measured visually from the side of the holding member (dl). When setting the gap, it is best to place a plate with the same dimensions as the desired gap between the object d and the tube, and push the tube until it hits the surface of the plate.In this modification, the holding member (bl By forming the contact surface (b5Xb6) on the automatic bonding machine, the structure that keeps the gap H between the holding member (b) and the object (d) constant and the holding member ( (b) The structure for moving up and down becomes unnecessary, and if the mechanism can be greatly simplified, the gap can be adjusted more accurately.

In any of the examples described above, the tube and the elastic member are relatively inexpensive, so when the tube is replaced, the elastic member can be removed from the holding member.

The embodiment described above can be further modified in various ways. For example, the tubes (aIX32Xa3) (a4) may be made of gold or crow, and the through holes of the elastic member into which these tubes are press-fitted may be changed. Alternatively, the through-mounting hole of the holding member into which the elastic member is inserted is not limited to a circular shape, but may have an appropriate cross-sectional shape.

Effects As explained above, with the tube holding device of the present invention, the amount of protrusion of the tube from the holding member can be adjusted very easily, which improves work efficiency.

In addition, in the case of tube replacement, even if the tube and the elastic member are discarded together, it is rational without increasing the cost unlike the above-mentioned conventional technology using a syringe needle.

The tube holding device of the present invention does not have the above-mentioned automatic adhesive properties, but can also be widely used in machines that use tubes to apply substances such as chemicals or paints onto objects, and can be used in a wide range of applications. This is an advantage.
