Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention controls a nozzle body as a tool in five axial directions with respect to a machining surface of a shoe main body as a workpiece, and drives the nozzle body at a desired position. The present invention relates to a sizing machine for shoes, which is adapted to perform sizing with a width and a desired thickness.

[Conventional technology]

2. Description of the Related Art Conventionally, in shoemaking machines, there is a sizing machine for shoemaking for automatically applying an adhesive to the outer peripheral portion of the lower surface of the shoe body in order to bond the outsole and the shoe body (upper).

As an example of the conventional gluing machine, a pair of left and right pair of shoe molds fixed upward on the processing table with the shoe main body (instep) covered is attached to the upper and outer edges of the upper and lower sides of the shoe mold. While the detection piece portion mounted on the carrier (moving body) movably combined in the direction orthogonal to the direction is engaged along the outer edge portions of the left and right shoe molds, the nozzle body is left and right as a workpiece 1 By following the pair of shoe molds, each is moved to apply adhesive from the nozzle body as a tool to the outer edge of the upper surface of the left and right shoe bodies.
There was a method called.

[Problems to be Solved by the Invention]

By the way, a pair of left and right shoes constitutes one pair of shoes, and the shape thereof is substantially bilaterally symmetric, and the left and right shapes are different. For example, when considering one shoe, the shape of the bottom surface is the inner part located on the arch side with respect to the outer part located on the heel side, and the rear end part on the heel part side with respect to the tip part on the toe side. However, the machining conditions on the machined surface are not constant, such as the fact that the shape of the curved plane differs abruptly, and the arched portion becomes a recess with respect to the flat portion, causing ridges and valleys.

Further, in the above-mentioned gluing machine whose technical essential is so-called "tracing", the nozzle body is made to follow the detection pieces engaged with the left and right shoe molds while the nozzle body is attached to the shoe body as the workpiece. By relatively moving, the adhesive is applied to the outer peripheral portion of the upper surface of the shoe body, and the gluing work is performed.

For this reason, this method has poor responsiveness when the nozzle body as a tool moves with respect to the work piece, and the movement error and the like increase, so that the nozzle body can move with high accuracy following the work piece surface. There wasn't. Therefore, there is an inconvenience that the glue cannot be applied to the desired position of the shoe body with respect to the work piece and the glue cannot be applied to the desired width and the desired thickness, and the processing accuracy and the production efficiency of the pair of left and right shoes are low. Moreover, since the number of parts is large, there has been a disadvantage that a lot of time and labor are required for production and assembly and the cost is increased.

[Means to solve the problem]

The present invention has been made in view of the above points, and is orthogonal to the longitudinal direction of the shoe main body as a workpiece to be set and fixed to the support table provided on the processing table via the shoe mold. 3 in the longitudinal direction, the Y-axis direction as the longitudinal direction of the shoe body, and the Z-axis direction orthogonal to the X-axis direction and the Y-axis direction.
In addition to the carrier that is movable on the processing table so as to be movable in the three-dimensional direction and the carrier that is movable in the three-dimensional direction,
A nozzle body as a tool mounted on the carrier so as to be swingable in two axial directions around an axis parallel to the axial direction and around the axis parallel to the Y-axis, and the shoe last as a model Of the three-dimensional direction and the two-axis direction are stored in the computer by selecting some points along the outer edge of the shoe last on the coordinates consisting of the axis of the plane longitudinal direction and the axis orthogonal to the longitudinal direction. And a control motor for controlling and driving the carrier and the nozzle body in the two axial directions based on the processing data. The control motor is controlled and driven. By determining the working path of the nozzle body by doing the distance between the workpiece and the jet outlet of the nozzle body,
We adopted a means to control and drive the mounting angle of the nozzle body according to the processing conditions such as the plane curve, peaks and valleys of the surface to be processed.

[Action]

A pair of right and left shoe bodies (insteps) as a work piece is covered on the processing table, and either the left or right shoe mold is set and fixed upward with the bottom surface facing upward.

Next, the determining means detects and determines whether the set shoe type is the left or right shoe type.

Corresponding to the difference in the discrimination result, one of the left and right shoe models is used as a model, and the number on the coordinate formed by the Y-axis direction as the longitudinal direction of the shoe body and the X-axis direction orthogonal to the longitudinal direction. At the point selected at the point, the tool moves in a three-dimensional direction in the Y-axis direction as the longitudinal direction of the shoe last, the Y-axis direction orthogonal to the longitudinal direction, the Z-axis direction orthogonal to the X-axis direction and the Y-axis direction, and Based on one of the left and right machining data produced by storing in the computer information about the swing of the tool in the two axial directions around the axis parallel to the X-axis direction and around the axis parallel to the Y-axis direction (basic ) Is uncorrected or corrected to determine the working path of the nozzle body as a tool with respect to the shoe body as a workpiece by the drive signal generated from the processing data, and the carrier drive Controls and drives the control motor in three dimensions and at the same time controls and drives the mounting angle of the nozzle body as a tool around an axis parallel to the X-axis direction or around an axis parallel to the Y-axis direction to attach glue to the shoe body.

One embodiment of the present invention has the above-described structure.
As shown in FIG. 1, in order to perform a sizing operation on a portion corresponding to the sizing margin of the upper surface outer edge portion 1a of the pair of shoe bodies 1, as shown in FIG. 1, a support rod above the support base 9 installed on the processing table 2 is used. For example, the left shoe main body 1 as a workpiece is capped and set on, for example, the left shoe mold 7 that is detachably fixed to.

Then, as shown in FIG. 13, when the power button and the set button on the operation panel P provided on one side of the apparatus are pressed, the toe portion 1b of the shoe body 1 is moved to the toe clamp mechanism portion 10 '.
The heel portion 1c is held by the left and right holding arms 10a, 10a of the clamp mechanism portion 10 against the elastic force of the coil springs 10b, 10b (see FIGS. 1 and 11). At this time, the cylindrical detection component 10c is always spring-biased in the center by the biasing force of the coil springs 10b, 10b divided into two.
The change in the movement amount of the detection component 10c, which moves with the movement of the sandwiching arms 10a, 10a when the shoe mold 7 is clamped by the pair of sandwiching arms 10a, 10a, is applied to the switch Sw which allows the detection component 10c to come into contact with each other. To detect whether the shoe type is the left or right shoe type 7.

Whether the left or right of the shoe mold 7 set in this way is either left or right 1
It is detected whether or not it is matched with one processing data formed by using one shoe model 7 as a model. That is, the axis Y that coincides with the Y-axis direction Y as the longitudinal direction of one shoe last 7.
₁ and an axis X ₁ that coincides with the X-axis direction X orthogonal to the longitudinal direction
1 on the coordinate 8 (see Fig. 12) formed from
By storing the information of points a, b, ha, d, h, d, h, d, h, d, d, r, n, and l selected at several points on the inside and outside of the outer edge of the two shoe patterns 7. When the shoe mold 7 fixed as a set corresponds to one formed machining data, the control motors M ₁ and M ₂ are driven by the drive signal generated from the computer based on the information value stored in the machining data. The carrier 3 is controlled and driven in the Y-axis direction Y or the X-axis direction X by controlling the rotation speed and direction of the carrier 5, and the carrier 5 is controlled in the Z-axis direction Z by the control of the control motor M _3. The adhesive is moved and discharged from the nozzle body 6, and the upper surface outer edge portion 1a of the shoe body 1 is
Apply adhesive to.

For this purpose, the nozzle body 6 is positioned at a slight gap, for example, at the toe portion 1b on the center bisector N of the upper outer edge portion 1a of the shoe body 1.

That is, as shown in FIGS. 1 and 2, the control motor M ₃
Is transmitted to the first rotating body 37 via the belt 36a to rotate, and this rotation is further transmitted to the pulley 38 and the belt 36b.
The second rotating body 39 is rotated and driven by being transmitted to the second rotating body 39, and the rotation of the second rotating body 39 is rotated by the timing belt 42 via the pulley section 40.
The nozzle body 6 is positioned on the center bisector N of the toe portion 1b of the shoe body 1 with a slight gap by lowering the carrier 5 fixed to.

This is because, for example, as shown in FIG. 14, the nozzle body 6 as a tool with respect to the outer peripheral edge portion 1a of the upper surface of the shoe body 1 as a work piece has a nozzle body about the eccentric rotation axis HL that is slightly inclined outward. The brush portion B at the lower end is rotated by, for example, clockwise rotation by the drive of the motor of the unit U, and abuts against the shoe body 1 as a workpiece so that the mounting angle forms an open gap K on the inner peripheral side. . Therefore, since the adhesive discharged from the nozzle opening 6a to the surface to be processed of the shoe body 1 as a workpiece is discharged to the inner peripheral side, even if the adhesive is agitated by the rotation of the brush part B, the outer edge of the upper surface of the shoe body 1 is agitated. The adhesive does not protrude from the portion 1a.

Then, by rotating the control motor M ₁ starting from this point, the first rotating body 16 is rotated via the pulley 14 and the belt 15a, and then the rotation of the first rotating body 16 is changed to the pulley 17 and the belt 15b. Through the second rotating body 1
8 is rotated and driven, and this rotation is further caused to rotate the timing belt 21 via the pulley portion 19 to rotate the carrier 3
Movably in the Y-axis direction Y along the guide rails 13, 13 and rotationally driving the control motor M ₂ to rotate the first rotating body 27 via the belt 26 a and the pulley 25, and then the By rotating the second rotating body 29 through the pulley 28 and the belt 26b by rotating force, and by rotating the timing belt 32 through the pulley portion 30 by rotating the second rotating body 29, the carrier 4 is guided to the guide rail. 24, 24 so as to be movable in the X-axis direction X, and further control the rotation of the control motor M ₃ by the pulley 35,
The first rotating body 37 is passively driven to rotate via the belt 36a, and then this rotation is rotated to rotate the second rotating body 39 via the belt 36b via the pulley section 38, and further to the timing belt via the pulley section 40. By rotating 42 to move the carrier 5 up and down in the Z-axis direction Z, the nozzle body 6 is moved substantially all around the upper outer edge 1a of the shoe body 1,
Alternatively, leaving an adhesive portion such as a heel as a heel component, the adhesive agent is discharged from the nozzle port 6a by moving in the X-axis direction X, the Y-axis direction Y, and further in the Z-axis direction Z over approximately a half circumference or more, and the brush portion B The coating is applied while being uniformly stirred by the rotation of (see FIG. 1 to FIG. 5 and FIG. 14).

At this time, the opening angle K is formed inside the nozzle opening 6a of the nozzle body 6 with respect to the surface to be processed by inclining the mounting angle of the shoe body 1 as the workpiece of the nozzle body 6 slightly outward. The adhesive is discharged to the side to prevent the adhesive from squeezing out from the outer edge portion 1a of the upper surface. Moreover, since the moving condition such as an upslope in the longitudinal direction of the shoe body 1 from the toe portion 1b to the arch part or a downslope (inclination) to the arch part is different from a simple smooth surface,
The adhesive is applied at a desired position while adjusting the moving angle of the nozzle body 6 related to the opening angle K with respect to the surface to be processed of the shoe body 1 according to the situation of the surface to be processed of the shoe body 1. Further, the application thickness of the adhesive can be adjusted and adjusted by adjusting the degree of contact of the nozzle body 6 with the outer edge portion 1a of the upper surface of the shoe body 1, so that a beautiful finish without application unevenness can be obtained.

The nozzle body 6 is attached to the relay arm 44 about the axis O ₁ by rotating the motor shaft m ₄ of the control motor M ₄ of the θ angle adjusting means 43 clockwise or counterclockwise. The nozzle body unit U is adjusted by rotating around the axis (left-right direction) with respect to the outer peripheral edge portion 1a of the upper surface of the shoe body 1 as the surface to be processed (first
(See FIGS. 6, 6, 7 and 14).

In addition, X that is orthogonal to the longitudinal direction of the shoe body 1 such as the arch part
The adjustment of the mounting angle of the nozzle body 6 with respect to the shoe body 1 in the axial direction X is performed because the drive wheel 50 is rotated and driven by the control motor M ₅ being rotated and driven.
One of the passive wheels 52 is rotated by one of the timing belts 51 wound around A and 50B, and the other of the passive belts 52 is rotated by the other timing belt 51 via the intermediate wheel 50C. The outer peripheries of the wheels 52, 52 come into contact with the guide rails 46 having a substantially quarter moon shape and rub against each other, so that the mounting frame 48 to which the nozzle unit U is mounted is attached.
Rotates in the X-axis direction X, which is a direction orthogonal to the longitudinal direction of the shoe body 1 about O ₂ along the guide rail with respect to the shoe body 1 as a surface to be processed (FIGS. 1 and 8). , 9th
See FIG. 10). The application width of the adhesive is determined by the size of the nozzle body 6 when the discharge amount is constant.

In this way, when the desired adhesive has been applied to the upper surface outer edge portion 1a of the left shoe body 1, the nozzle body unit U is lifted together with the carrier 5 by driving the control motor M ₃ to lift the nozzle body unit from the shoe body 1. 6 is released, and the gluing work is completed.

In addition, as described above, the holding arm 10a of the clamp portion 10,
Detecting component 10c of discriminating means 11 always energized in the middle by coil springs 10b, 10b provided between 10a.
When it is determined that the shoe last 7 set and fixed on the processing table 2 is the one on the right side due to the change in the movement amount, the correction value setting means S ₁ , provided on the operation panel P, _{S 2, S 3, S 4} , S 5, S 6, S 7,
By operating the desired switches S ₈ , S ₉ , S ₁₀ , and S ₁₁ , the axis Y ₁ that coincides with the Y-axis direction Y as the longitudinal direction of the left shoe last 7 and the X-axis direction X coincide with each other. Axis X ₁

In the above description, the case where the gluing is automatically performed based on the discrimination between the right and left of the shoe type has been mainly described, but in addition to this, in the present device, by measuring the actually measured length of the shoe type by the sensor, Corresponding to this measured length, the X-axis direction X,
The same kind of shoes can be used for the elongation rate of the movement of the nozzle body 6 that moves around the axis O ₁ line parallel to the Y axis direction Y, the Z axis direction Z, and the X axis direction X, and the axis O ₂ line parallel to the Y axis direction Y. It is possible to easily perform the gluing work corresponding to each size automatically by changing variously under the mold.

〔The invention's effect〕

As described above, according to the present invention, the movement of the nozzle body with respect to the machining surface is selected at several points on the coordinates with the shoe model as a model, and the X-axis direction, which is the direction orthogonal to the longitudinal direction of the workpiece, the longitudinal direction. Information about the working passage of the nozzle body in the Y-axis direction as a direction, the Z-axis direction orthogonal to the X-axis direction and the Y-axis direction, and a total of 5 axis directions around axes parallel to the X-axis direction or the Y-axis direction, respectively. The control motor is controlled and driven based on the processing data formed by storing the data in the computer, and the nozzle body is used for processing conditions such as a plane curve, peaks, and slopes at the outer edge of the upper surface of the shoe body as the workpiece. Since you can move in a fine and responsive manner,
Highly accurate gluing can be performed on the shoe body as a work piece with little movement error.

Therefore, the production efficiency is improved, the structure is simplified, and the number of parts is reduced. Therefore, the production and assembly are simplified, and the cost is reduced.
