Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel method for producing a synthetic resin mat with great longitudinal wave utilization.

Conventionally, a mat body of an appropriate shape is formed by combining a plurality of unit mat blocks molded from soft synthetic resin with elasticity, and the outer periphery of the mat body is prevented from warping or being damaged. In order to clean shoes, a belt-like frame made of soft synthetic resin was arranged in a surrounding manner to form a synthetic resin mat of the highest quality, which was used for cleaning shoes, etc.
It is publicly known.

In this case, the unit mat blocks were joined together by Jinyao heat welding, but joining the unit mat blocks together by such heat welding required a skilled technique and a great deal of time and effort, thus increasing costs. However, the major drawback was that the joints were not beautiful.

On the other hand, when high-frequency welding, which has recently become popular, is applied to the joining of unit mat blocks, the insect acidity is extremely high, the finish is beautiful, and there is little variation in contact strength. Although this advantage exists, there is a size KuIII that can be welded, and this point has been a major bottleneck, and solving this problem has been a concern in the industry.

The method of the present invention has a structure in which high frequency welding and thermal welding can be skillfully combined to completely eliminate the drawbacks of high frequency welding. The object of the present invention is to solve the problems in this field all at once by combining groups very easily and making it possible to manufacture mats of various sizes arbitrarily and at low cost.

Next, the I! of the present invention! The structure will be specifically explained with reference to the drawings showing one embodiment.

(1) is the locking side edge of each unit mat block, and in a group of unit mat blocks molded from soft synthetic resin and having eight basic square shapes of the same size, one side edge is vertically Divide into two equal parts, each (by cutting the upper and lower edges of the side edges in the axial direction, the lower protrusion 2) and the upper protrusion w5.
It shall be formed in a symmetrical shape with a prisoner on each side.

That is, in the side edge part (1) for locking, as shown in FIG. As shown, the other half is composed of an upper protrusion (5) and a lower notch (5), and is configured in a reverse staircase shape, so that the first half and the other half form a symmetrical shape. It is something to do.

In this case, the downward protrusion Q of the locking side edge (1)
The edge line of the upper edge of ) and the edge line of the lower edge of the upper protrusion
If both of them are made to coincide with the center line of the locking side edge (1), mutual locking of adjacent unit mat blocks and high leg wave fusion, which will be described later, will be made easy, reliable, and effective. , which is extremely convenient.

The method for producing a synthetic resin mat according to the present invention is as follows:
First, when forming the mat block group, the second side edge is used as the locking side edge (1), and the 21I of the umbrella is used! E... of a group of unit mat blocks for corner parts whose I edges are the normal side edges of a square shape.

The 311 edge is used as the locking side edge (1), and the ◆11I
A unit mat block group for the edge where the fl edges are square-shaped and the far side edges are closed. Six groups of unit mat block groups (91-...(9)) are prepared.

In the method of the present invention, in order to obtain the mat body (L(I) using the five types of unit mat block groups described above,
First, as shown in FIGS. 1 and 4, the corner unit mat block V) is attached to its two normal side line portions 46), (6).
is placed in a position that forms the corner edge of the mat body curve,
Place the edge unit mat block (8) at a position where its normal side edge part forms the edge of the mat body (IQ), and then place the internal unit mat block (9). , these three types of unit mat blocks (71, (81, (91
If the desired mat body αe shape is formed by placing a plurality of mat bodies adjacent to each other, the adjacent stopping side edges (11, (11) are This is a simple and reliable way to form a mutually stopped state, and at the same time, the desired peripheral edge of the mat main body αl is a normal working edge including the four corners fII, as shown in Figures 1.1 and 4. Department (
6)... Due to this unfortunate conjunctive relationship, a band plate-shaped frame I made of soft synthetic resin... (2) Ill that can be joined is formed at once.

In the method of the present invention, in the above embodiment, first, the adjacent locking JII side edges (1), (1) are high-frequency welded. Then, the side edge for adjacent locking (1)
, (11 is a structure in which the vibration surface during high-frequency welding is large and the heat generation efficiency is noticeable in the dowel locking mode shown in Figs. 2 and 3. Therefore, frequency welding is extremely difficult. IK is carried out effectively and quickly, making it possible to manufacture a mat body with a beautiful finish simply, quickly, easily and at low cost.

In the method of the present invention, the normal side edge (6) having a straight circle forming the peripheral edge of the mat main body obtained as described above... soft synthetic at
om's strip plate-like frame l・Φ...(2) to IA#1l14
By melting, one synthetic resin mat (2) is obtained.

In this case &C, the joining of the strip-shaped frame to the mat main body is by heat welding, so there is no restriction on the size of the target object as seen in the above-mentioned high-frequency welding. It goes without saying that there will be no hindrance to joining the long strip-shaped frame I...circle.

As is clear from the above structure, the effects of the method of the present invention are as follows:
It consists in the following points.

(a) Three types of unit mat block groups are manufactured in advance,
%: If the mat bodies 111 are combined in the variegated chambers as shown in FIG. 4, the mat body 111 of any shape can be easily and reliably formed, which is very convenient.

Incidentally, in the method of the present invention, in view of the limitation of the size of the target object in the high-frequency observation method, for example, the fourth
After forming the mat body part αe with the combination of (4) and (Of in the figure, it is also possible to weld these two mat body parts - to the barge to form a large mat body part on the barge. It is.

(b) When placing each unit mat block, the fourth
As shown in the figure number, it is sufficient to simply place the normal side edges of unit mat blocks of class 3Ill on the outer peripheral edge of the desired mat body dI shape, in other words, to lock adjacent unit mat blocks. There is no need to consider the directionality of each unit mat block, and in this respect, workability when arranging each unit mat block is extremely good.

(ol) From the front side of the first locking side where the adjacent locking side edges (1) and (1) intersect, the expansion tendency at the time of jIIi frequency landing is large and generates heat.In other words, the efficiency is extremely good. Mutual bonding of the unit mat plotters is carried out by making full use of the advantages of high frequency welding, and the periphery of the mat is usually formed from the side edges (6). By doing so, it is possible to perform elegant heat welding of the long strip-shaped crushed bodies I...φI, and thus the above-mentioned high frequency welding is possible.
By overcoming the size limitations of 6, it is possible to imitate any large-diameter synthetic resin mat.
By combining li, the advantages of high frequency welding can be realized with any size of 6cg kN,
The greatest feature or effect of the present invention lies in this point.

(41) Due to its structure, it can be manufactured at an extremely low cost.
