Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, for example, automatically applies an adhesive to a predetermined position on the outer edge of a shoe mold of the outsole as a workpiece to which the upper is adhered, in a desired width and a desired thickness. TECHNICAL FIELD The present invention relates to a sticking method for a shoe making machine and a sticking machine for carrying out the same.

[0002]

2. Description of the Related Art Conventionally, in a shoe making machine, a shoe glue for applying an adhesive to a book sole as a work piece for adhering a bottom outer edge of an upper as a shoe main body to the book sole. There was an accessory.

Some conventional examples of the above-mentioned pasting machine will be described with reference to FIGS. 8 to 15. First, an example thereof will be described with reference to FIGS. 8, 9 and 12 and FIG.
Rolls R1 and R2 that are rotated in the opposite direction by 10 are provided opposite to each other with a gap K1 between them, and the lower roll R
1 is arranged in a storage tub P containing an adhesive S, and a bottom H as a flat workpiece as shown in FIGS. 12 and 13 is provided in a gap K1 between the rolls R1 and R2. By inserting it, the bottom H is moved by the friction of the rolls R1 and R2, and the adhesive S is applied by the roll R1.
Is applied to the entire bottom surface of the outsole H, which is turned upside down.

A second conventional example of the pasting machine will be described with reference to FIGS. 10 to 15. A frame mold I formed in a substantially shoe shape.
The book bottom H is inserted into the inside and fixedly set on the machine base J, and the nozzle body Q is provided above the machine base J in a direction substantially perpendicular to the longitudinal direction Y of the book bottom H and a direction X orthogonal to the longitudinal direction Y. The stylus is configured to be movably provided in two directions by motors M11, M12 and the like, and is provided with a stylus pin SP that follows along the outer edge of the shoe mold of the mold I. -The nozzle body Q is moved in the longitudinal direction Y of the mold I while following the outer edge of the shoe mold of the mold I by the pin SP.
Also, the adhesive S is applied from the nozzle body Q to the outer edge of the shoe last of the outsole H while moving in the direction X orthogonal to the longitudinal direction Y.

[0005]

However, FIG. 8 and FIG.
The first above-mentioned pasting machine shown in FIG. 2 is a gap K1 between rollers R1 and R2 which are rotatably opposed to each other in the opposite direction at the time of pasting.
Since the book bottom H as a workpiece is inserted into the inside so that the adhesive S is applied to the entire lower surface of the book bottom H, the shape of the book bottom H itself is as shown in FIGS. 12 and 13. If it is not flat, the moving speed of the outsole H due to the friction between the rollers R1 and R2 is not averaged, and a slow unevenness is generated, or a thin and uneven coating is applied to the application of the adhesive S by the roller R1. ..

Therefore, in such a pasting machine, as shown in FIG.
And, as shown in FIG. 15, a heel portion h1 is provided at the rear portion of the lower surface of the outsole H as a workpiece to cause a step, or the upper surface of the outsole H has a shoe-shaped outer edge portion where an adhesive surface with the upper is attached. It was not possible to carry out the glueing work on the outsole H having the standing up edge portion h2 for covering the above.

In the second conventional pasting machine, the stylus pin SP follows the mold I so that the nozzle body Q is perpendicular to the longitudinal direction Y of the mold I and the direction X orthogonal to the longitudinal direction Y. Since the adhesive S is applied along the upper surface outer edge portion H1 of the outsole H by making the nozzle body Q movable as a tool, the nozzle body Q as a tool is used as a workpiece. The responsiveness when moving to the outsole H was deteriorated, and a set error occurred in fixing the set of the outsole H to the machine base J. Further, since the movement error of the nozzle body Q with respect to the outsole H becomes large, the nozzle body Q can be highly accurately
Was unable to move following the work surface of the outsole H.

Then, a sloped portion h3 or a concave portion corresponding to an arch portion is formed from the inside of the upper surface of the outsole H or from the toe portion toward the heel portion, and further, the raised edge portion h2 is raised at the outer edge portion of the shoe mold. In the outsole H in which is formed the nozzle body Q
Since the gap of the discharge port of the above is not uniform with respect to the work surface of the outsole H, the application of the adhesive S is insufficient,
On the contrary, there is a disadvantage that the adhesive S cannot be applied to the outer edge portion H1 of the upper surface in a desired width and a desired thickness due to the adhesive S protruding.

By the way, a pair of left and right shoes constitutes one pair of shoes, and the shape thereof is substantially bilaterally symmetric, the left and right shapes are different, and the dimensions are not the same. For example, in FIG.
As shown in FIG. 14, when one shoe is considered, the shape of the outsole H as the bottom surface is that the inner portion G2 located on the arch side with respect to the outer portion G1 located on the ankle side, and the toe side. The curved shape of the plane differs slightly between the tip of the heel and the rear end of the heel side, and the arched part is a recess with respect to the flat part, resulting in a ridge and a slope h3. Conditions are not constant.

Therefore, in the pasting machine shown in FIGS. 10 and 11, one pair of left and right molds I is required separately, and even in the same type of mold I, the width and length (total length) are gradually increased. It is necessary to prepare several different sizes, the equipment cost will be high and the maintenance and management of these equipment will not require a lot of installation area. It is necessary to select the size of the pair of molds I, I and set them on the machine base J, which requires time and labor for the work, and the work of gluing is inefficient. Therefore, there is an inconvenience that the yield is low.

Therefore, the present invention has been made in order to correct the above-mentioned conventional drawbacks, and whichever left or right outsole is set and fixed to any set position with respect to the processing table, the left or right outsole is fixed. As a model, several points along the outer edge of the upper surface of the shoe last are detected by the cursor of the image processing unit, and the data is stored in the computer. Even if the processing conditions are not uniform due to the formation of sloped parts, recesses, and even raised edges, the adhesive is applied to the desired width and thickness with high responsiveness automatically and with high precision. The purpose is to carry out the work efficiently without doing the work.

[0012]

Then, as shown in FIG. 7, the third cursors 20 and 21 are orthogonal to the longitudinal direction of the shoe last K at a position within a desired distance from the toe 3A, for example, 1.5 to 2.0 cm. Two intersections 18a and 18b between the parallel line X2 with respect to the axis X and the outer edge of the shoe last K are detected, and a line segment L1 between these two intersections 18a and 18b is obtained.

Similarly, from FIG. 7 to the fourth cursor 22,
A desired distance from the heel portion 3B by 23, for example, 1.5 to
Y in the longitudinal direction of the shoe last K at the position inside 2.0 cm
Parallel lines X2 and X3 with respect to an axis X1 orthogonal to the axial direction Y
And two intersections 19a and 19b with the outer edge of the shoe last K are detected, and a line segment L2 between these intersections 19a and 19b is obtained.

Further, the midpoint t of the two line segments L1 and L2
1 and t2 are the first cursor 16 and the sixth cursor 1 respectively
And 7 move and detect. When the two detected midpoints t1 and t2 are obtained, the two midpoints t1 and t2 are calculated.
The length L of the outsole 3 set and fixed on the working table 2 is measured on a line passing through, that is, the center bisector N as the central axis.

In this way, as shown in FIG.
After the length measurement is performed, the storage unit 2 of the central processing unit CPU
The workpiece fixed on the machining table 2 by driving the motor M1 as a drive source through the control unit 30 by the numerical value calculated by the arithmetic unit 29 based on one machining data stored in 8 From the set position SI (position indicated by the solid line) to an appropriate machining reference position FI (position indicated by the imaginary line) from the set position SI (the position indicated by the solid line) depending on whether the set angle α of the outsole 3 is positive or negative (+, −). The processing table 2 is rotated in either forward or reverse direction, and the angle is corrected.

Therefore, every time the gluing work is carried out, the proper machining reference position FI is set regardless of the set angle α of the book sole 3 as a workpiece to the work table 2 at any set angle α. By rotating the machining table 2 in either forward or reverse direction, the angle of the book bottom 3 is corrected, and the central axis of the book bottom 2 and the central axis of the nozzle body 5 coincide with each other. This is always a proper position for the machining start position (center axis) of the outsole 3 as the workpiece with respect to the nozzle body 5 as a tool, that is, as the center axis of the upper outer edge 3a of the shoe last K of the outsole 3. It means that the nozzle body 5 is set on the center bisector N of, for example, the toe portion 3A with a slight gap.

After the angle correction of the outsole 3 is performed, a motor as a drive source is generated by a signal from the control unit 30 of the central processing unit CPU based on the processing data used when discriminating between right and left. By controlling and driving M2, M3, and M4, the carriers 3 and 4 are moved in the Y-axis direction Y or the X-axis direction X, respectively, and the carrier 33 is moved in the Z-axis direction Z. S is applied to the upper surface outer edge portion 3a of the outsole 3 as a workpiece.

To this end, the nozzle body 5 is positioned at a slight gap, for example, at the toe portion 3A of the center bisector N of the upper outer edge portion 3a of the outsole 3 as a workpiece. That is, as shown in FIG. 1 and FIG. 2, a carrier having a nut portion 51 meshed with the screw rod 50 by rotating the screw rod 50 via the coupling 49 by the rotational force of the motor M4. 33, and the nozzle body 5 is positioned on the central bisector N with a slight gap.

This includes, for example, the outsole 3 as a workpiece.
The nozzle body 5 as a tool with respect to the outer peripheral portion 3a of the upper surface of
The brush portion 7 at the lower end is driven by driving the motor M7 of the nozzle body unit U with the eccentric rotation shaft facing slightly outward as the center.
4 is rotated clockwise, for example, since the mounting angle is discharged to the inner peripheral side with respect to the book bottom 3 as a workpiece, the top surface of the book bottom 3 is also stirred when the brush portion 74 is rotated. The adhesive S does not protrude from the outer edge portion 3a.

Starting from this point, the pulley 36, the belt 37, and the pulley 39 are rotationally driven by rotationally driving the motor M2 to rotate the screw rod 38.
Is rotated to move the carrier 31 having the nut 40 that meshes with the screw rod 38 in the Y-axis direction Y, and also to rotate the motor M3 to drive the pulley 43, the belt 44, and the pulley 46. Rotate the screw rod 45,
5 allows the carrier 32 meshed with 5 to move in the X-axis direction X, and further rotates the motor M4 to rotate the screw rod 50 as described above.
By moving the carrier 33 having the nut portion 51 that meshes with the screw rod 50 so as to be able to move up and down in the height direction of the Z-axis direction Z, the nozzle body 5 is moved to substantially the entire outer edge portion 3 a of the upper surface of the outsole 3. In the case where a suspended edge portion 3c standing on the outer circumference or the outsole 3 is formed, this suspended edge portion 3c
The adhesive is ejected from the ejection port of the nozzle body 5 over substantially the entire outer circumference including, and is applied while being uniformly stirred by the rotation of the brush portion 74.

At this time, the mounting angle of the outsole 3 as the workpiece of the nozzle body 5 is tilted slightly outward so that the opening angle not shown in the drawing is inside the nozzle opening of the nozzle body 5 with respect to the surface to be processed. Is formed to discharge the adhesive S to the inner peripheral side, so that the adhesive S is prevented from protruding from the outer edge portion 3a of the upper surface.

Moreover, as shown in FIGS. 12 and 13, not the sole 3 having a flat upper surface, but the sole from the toe portion 3A to the arch portion on the upper surface of the sole 3 as shown in FIGS. The moving conditions of the inclined portion 3b, such as an upslope in the longitudinal direction of 3 or a downslope reaching the arch part (slope), are different from those of a simple smooth surface. The adhesive S is applied at a desired position so that the adhesive S does not squeeze out while adjusting the movement angle of the body 5 with respect to the opening angle of the outsole 3. Moreover, since the application thickness of the adhesive S can be adjusted and adjusted by adjusting the degree of contact of the nozzle body 5 with the outer peripheral portion 3a of the upper surface of the outsole 3, there is no uneven coating.
It has a beautiful finish.

As for the mounting angle of the nozzle body 5, the motor shaft m5 of the motor M5 of the β angle adjusting means 52 rotates clockwise or counterclockwise and the drive arm 58 rotates about the axis O1. The pivot 5 is attached to the drive arm 58.
Since the main arm 60 and the sub arm 62, whose one ends are pivotally connected by 9, 61, move in parallel, respectively, the main arm 6
No. 0 and the other end (tip) of the sub arm 62, the nozzle body unit U rotates about the axis O1 (left-right direction) with respect to the upper outer edge portion 3a of the outsole 3 as the surface to be processed. Is adjusted (see FIG. 2).

Further, the attachment angle of the nozzle body 5 to the outsole 3 in the X-axis direction X orthogonal to the longitudinal direction of the outsole 3 such as an arch part is adjusted by rotating the motor M6 to rotate the pulley 68 and the belt 69. Since the input shaft 71 rotates via the input shaft 71, the shaft O2 as the output shaft rotates via the speed reducer 72 with respect to the input shaft 71. Therefore, the carrier 33 to which the nozzle unit U is attached rotates about the axis O2 as an output axis orthogonal to the axis O1 in the X-axis direction X as a direction orthogonal to the longitudinal direction of the outsole 3 (FIG. 3).
reference).

At this time, the coating width of the adhesive S is determined by the size of the diameter of the nozzle body 5 when the discharge amount is constant.

In this way, when the desired adhesive S has been applied to the upper surface outer edge portion 3a of the left outsole 3, the motor M4
Drive the nozzle body unit U together with the carrier 33 to separate the nozzle body 5 from the outsole 3 to complete the gluing work.

The left and right shoe molds K are discriminated depending on whether or not the machining data of the shoe mold K of the outsole 3 set on the machining table 2 coincides with the machining data.

When it is determined that the outsole 3 as the work piece set and fixed on the processing table 2 is the right shoe shape K in this way, the third cursor 2 of the image processing section 14 is determined.

Two intersections 18a and 18b with the part are detected, and the fourth cursors 22 and 23 move the inside of the heel part 3B of the shoe last K by a desired distance, for example, 1.5 to 2.0 cm. Two intersections 19a and 19b of the parallel line X3 parallel to X1 orthogonal to the axis Y1 that coincides with the Y-axis direction Y of the position and the outer edge portion of the shoe last K are detected. After that, by the first and second cursors 16 and 17 of the image processing unit 14,
