Description

[Detailed Description of the Invention] [Industrial Application Field] This invention controls and drives a nozzle body as a tool in 5-axis directions to a desired position on the processing surface of a shoe body as a workpiece. This invention relates to a shoe-making sizing machine that applies sizing to a desired width and thickness.

[Conventional technology]

Conventionally, shoe making machines include shoe making gluing machines that automatically apply adhesive to the outer edge of the lower surface of the shoe body in order to bond the outsole and the shoe body (upper).

To give an example of the conventional gluing machine described above, a pair of left and right shoe lasts is set and fixed facing upward on a processing table with the shoe body (upper) covered, and the outer edge of the upper surface of the shoe last is attached to the outer edge of the upper surface of the shoe last in the longitudinal direction The nozzle body is attached to the left and right 1 as a workpiece while engaging the detection piece mounted on a carrier (moving body) that is movably combined in a direction orthogonal to the left and right shoe lasts along the outer edges of the left and right shoe lasts. This is a so-called "tracing process" in which adhesive is applied to the outer edges of the upper surfaces of the left and right shoe bodies from a nozzle body as a tool by moving each last by following the pair of shoe lasts.
There was a method called

[Problem to be solved by the invention]

Incidentally, a pair of left and right shoes constitutes one pair, and the shape of the shoes is approximately symmetrical, but the shapes of the left and right shoes are different.

For example, when considering one shoe, the shape of its bottom is the outer part located on the section side, the medial part located on the arch side, and the tip part on the toe side and the rear end on the heel side. In this case, the machining conditions on the machining surface are not constant, such as the shape of the plane curve being different in slope and steepness, and the arch being concave with respect to the flat part, producing peaks and troughs and slopes.

In the above-mentioned gluing machine whose technical essence is so-called "profiling", the nozzle body is applied to the shoe body as the workpiece while following the detection pieces that are engaged with the left and right shoe lasts. By relatively moving the shoes, adhesive is applied to the outer edge of the upper surface of the shoe body, thereby performing a gluing operation.

For this reason, this method has poor responsiveness when moving the nozzle body as a tool with respect to the workpiece, resulting in large movement errors, so the nozzle body cannot move with high accuracy while following the workpiece surface. There wasn't. Therefore, there are inconveniences such as the glue not being applied to the desired position of the shoe body relative to the workpiece and sticking out, and the glue not being applied to the desired width and thickness, and the processing accuracy and production efficiency of a pair of left and right shoes are also low. Moreover, since the number of parts is large, it takes a lot of time and effort to produce and assemble, resulting in high costs.

[Means to try to solve the problem]

The present invention has been made in view of the above-mentioned points, and includes a shoe body as a workpiece to be set and fixed on a support stand provided on a processing table via a shoe last, and a shoe body that is perpendicular to the longitudinal direction of the shoe body. a carrier assembled on a processing table so as to be movable in three-dimensional directions: a longitudinal direction, a Y-axis direction as the longitudinal direction of the shoe body, and two axes orthogonal to the X-axis direction and the Y-axis direction; a nozzle body as a tool mounted on the carrier so as to be movable in two directions, and swingable in two axes around an axis parallel to the X-axis direction and around an axis parallel to the Y-axis direction; Using the shoe mold as a model, several points along the outer edge of the shoe mold are selected on the coordinates formed by the plane longitudinal axis of the shoe mold and an axis orthogonal to the longitudinal direction, and the three-dimensional direction and the two axes are selected. One piece of machining data is produced by storing direction information in a computer, and the carrier and the second machining data are produced based on the machining data.
The control motors are configured to control and drive the nozzle body in the axial direction, and by controlling and driving the control motors, the operating path of the nozzle body is determined and the jet of the workpiece and the nozzle body are controlled. A method was adopted in which the distance between the nozzle and the outlet and the mounting angle of the nozzle body were controlled and driven in accordance with the processing conditions such as the planar curve, peaks and valleys, and slope of the surface to be processed.

[For production]

A pair of left and right shoe bodies are placed on the processing table as workpieces (
Set and fix either the left or right shoe last (with the upper) facing upwards, with the bottom facing up.

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

Then, in response to the difference in the discrimination results, one of the left and right shoe lasts is used as a model, and the shoe last is modeled on the coordinates formed by the Y-axis direction, which is the longitudinal direction of the shoe body, and the X-axis direction, which is perpendicular to the longitudinal direction. Movement of the tool in three-dimensional directions in the Y-axis direction as the longitudinal direction of the last, the Y-axis direction perpendicular to the longitudinal direction, the X-axis direction, and the Z-axis direction perpendicular to the Y-axis direction at several selected points; Furthermore, based on machining data for either the left or the right, which is created by storing in the computer information regarding the swing of the tool in two axes around an axis parallel to the X-axis direction and around an axis parallel to the Y-axis direction ( By leaving the information unchanged or modifying the information (basic), the drive signal generated from the processing data determines the operating path of the nozzle body as a tool with respect to the shoe body as the workpiece, and controls the carrier drive. The motor is controlled and driven in three dimensions, and the mounting angle of the nozzle body as a tool is controlled and driven around an axis parallel to the X-axis direction or around an axis parallel to the Y-axis direction to apply glue to the shoe body. Do it automatically.

〔Example〕

The details of this invention will be explained below with reference to an embodiment shown in the drawings.

A brush part B, which can be freely rotated by a motor as a drive source built into the nozzle body unit U with HL as the center, is provided at the lower end, and opens inwardly between the inner peripheral side and the shoe body i, which serves as the surface to be machined.

Further, the adhesive discharged from the nozzle nozzle 6a of the nozzle body 6 is filled with a desired type and concentration of adhesive such as vinyl acetate in a container provided at a separate location. When the nozzle body 6 comes into elastic contact with the upper outer edge 1a with a slight gap K, discharge is discharged from the nozzle rod 6a along the upper outer edge 1a of the shoe body l, toward the inner circumference rather than the outer circumference. As a result, the nozzle body 6 is relatively moved around the entire circumference of the upper surface outer edge portion 1a.
Alternatively, the adhesive is applied by moving the adhesive over substantially the entire circumference of the upper outer edge portion 1a of the shoe body 1, leaving only the attachment points for heel components such as heels.

One embodiment of the present invention has the above-mentioned configuration.
To perform the gluing work on the portion corresponding to the glue margin on the upper surface outer edge portion 1a of the pair of shoe bodies 1, as shown in FIG. For example, the left shoe body 1 as a workpiece is placed and set on the left shoe last 7, which is detachably fixed to the shoe.

Then, as shown in FIG. 13, when the power button and set button on the operation panel P provided on one side of the device are pressed, the toe portion 1b of the shoe body l is moved to the toe clamp mechanism 10'.
The heel portion 1C is clamped by the left and right clamping arms 10a. supported by ioa against the elastic force of coil springs 10b, 10b (
(See Figures 1 and 11). At this time, the coil spring 10b divided into two. Since the cylindrical sensing component 10C is always spring-biased to the center by the biasing force of the clamping arm 10b, when the shoe last 7 is clamped by the pair of clamping arms lQa, lQa, as the clamping arms 10a, 10a move. A change in the amount of movement of the sensing component 10C that moves is detected by a switch SW with which the sensing component 10C can be freely contacted, and it is determined whether it is the left or right shoe last 7.

Then, the left and right side of the shoe last 7 set is 1.
It is detected whether or not it matches one processed data formed using two lasts 7 as models.

That is, the Y-axis direction Y as the longitudinal direction of one last 7
The inside and outside of the planar outer edge of one shoe last 7 on coordinates 8 (see FIG. 12) formed from the axis Y1, which coincides with the axis Y1, and the axis xl, which coincides with the X-axis direction The information on the points A, B, C, 2, H, H, T, C, R, N, L selected from several locations is set and fixed in a single processing disk formed by storing the information in a computer. When the shoe lasts 7 match, the information values stored in the processed data are used, and the carrier 3. 4 in the Y-axis direction Y or X-axis direction Adhesive is applied to the upper outer edge portion 1a of the main body 1.

To do this, the nozzle body 6 is positioned on the center bisector N of the upper outer edge la of the shoe body 1, for example, at the toe portion lb with a slight gap.

That is, as shown in FIGS. 1 and 2, the control motors M,
The rotational force is transmitted to the first rotary body 37 via the bell}36a to rotate, and this rotation is further transferred to the pulley 38 and the first rotating body 36b.
The rotation of the second rotating body 39 is transmitted to the second rotating body 39 to rotate and drive it, and further, the rotation of the second rotating body 39 is transmitted to the timing belt 42 via the pulley part 40, and the timing belt 42 is rotated.
By lowering the carrier 5 fixed to the shoe body 1, 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.

For example, as shown in FIG. 14, the nozzle body 6 as a tool is rotated around an eccentric rotation axis HL slightly tilted outward with respect to the outer edge 1a of the upper surface of the shoe body 1 as a workpiece. When the brush part B at the lower end is rotated, for example, clockwise by the drive of the motor of the unit U, the mounting angle is applied to the shoe body l as the workpiece so that an open gap K is formed on the inner circumferential side. come into contact with Therefore, since the adhesive discharged from the nozzle 6a onto the work surface of the shoe body 1 as a workpiece is discharged toward the inner circumference, even when it is agitated by the rotation of the brush part B, the adhesive is discharged from the outer edge of the upper surface of the shoe body 1. The adhesive does not protrude from 1a.

Then, by rotationally driving the control motor M1 using this point as a starting point, the first rotating body 16 is rotated via the bobbin 14 and the belt 15a, and then the rotation of the first rotating body l6 is controlled by the bobbin IJ17 and the belt. 15b to rotate and drive the second rotating body 18, and this rotation also rotates the timing belt 21 via the pulley portion l9 to move the carrier 3 along the guide rail 13.13 in the Y-axis direction Y. By making it movable and rotating the control motor M2, the first rotating body 27 is rotated via the belt 26a and the pulley 25, and then the rotational force is transferred to the pulley 28.
, bell} 26b, and the rotation of the second rotating body 29 causes the timing belt 32 to rotate via the pulley portion 30, thereby moving the carrier 4 onto the guide rail 24. In addition, the rotation of the control motor M3 is passively driven to rotate by the first rotating body 37 via the pulley 35 and the bell 36a, and then this rotation is driven by the pulley section. The nozzle body is rotated by rotating the second rotating body 39 by the bell 36b via the belt 38, and further rotating the timing belt 42 via the pulley portion 40 to move the carrier 5 vertically in the Z-axis direction 2. 6 is moved in the X-axis direction The adhesive is discharged from the nozzle 6a and applied while being uniformly stirred by the rotation of the brush portion B (see FIGS. 1 to 5 and 14).

At this time, by slightly tilting the mounting angle of the shoe body 1 as the workpiece of the nozzle body 6 outward, an open gap K is formed inside the nozzle hole 6a of the nozzle body 6 with respect to the workpiece surface, and the inner periphery is Dispense the adhesive on the side and the outer edge of the top surface of the adhesive! Prevent protrusion from la. Moreover, the movement conditions for the upward slope in the longitudinal direction of the shoe body 1 from the toe part 1b to the arch area, or the downward slope to the arch area (inclination) are different from a simple smooth surface, so
The adhesive is applied to a desired position while adjusting the movement angle of the nozzle body 6 with respect to the opening angle K of the shoe body 2 to the surface to be processed according to the condition of the surface to be processed of the shoe body 1 so that the adhesive does not protrude. Furthermore, by adjusting the degree of contact between the nozzle body 6 and the outer edge portion 1a of the upper surface of the shoe body 1, the thickness of the adhesive applied can be adjusted, resulting in a beautiful finish without uneven application.

The mounting angle of the nozzle body 6 is determined by rotating the motor shaft m of the control motor M4 of the θ angle adjusting means 43 clockwise or counterclockwise, so that the nozzle body 6 is mounted on the relay arm 44 around the axis O. Adjustment is made by rotating the nozzle unit U around the axis (in the left-right direction) with respect to the outer edge 1a of the upper surface of the shoe body 1 as the surface to be processed (Figs. 1, 6, 7, (See Figure 14).

In addition, an X perpendicular to the longitudinal direction of the shoe body 1 such as the arch of the foot
The attachment angle of the nozzle body 6 to the shoe body 1 in the axial direction X can be adjusted by rotating and driving the drive wheel 50 as the control motor M5 rotates and drives.

The belt 5l connects the other passive wheel 5 via the intermediate wheel 50C.
2 rotate, the outer peripheries of the driven wheels 52 and 52 come into contact with the approximately quarter-moon-shaped guide rail 46, and due to friction, the mounting frame 48 to which the nozzle body unit U is mounted is attached to the workpiece surface. The shoe body 1 rotates along the guide rail in the X-axis direction X, which is a direction perpendicular to the longitudinal direction of the shoe body 1, about 02 along the guide rail (FIGS. 1, 8, 9, See Figure 10>.The width of the adhesive application is determined by the diameter of the nozzle body 6 when the discharge amount is constant.

In this way, when the desired adhesive has been applied to the outer edge la of the upper surface of the left shoe body 1, the control motor M3 is driven to raise the nozzle unit U together with the carrier 5 and remove the nozzle body from the shoe body l. 6 is separated and the gluing work is completed.

Further, as described above, the clamping arm 10a of the clamp portion 10.
The detection component IOC of the discrimination means 11 is always energized in the middle by coil springs 10b, 10b provided between 10a.

In addition, in the above explanation, we mainly explained the case where gluing is performed automatically to distinguish between the left and right sides of the shoe last, but in addition to this, this device also uses a sensor to measure the actual length of the shoe last. Corresponding to this actual measurement length,
The elongation rate of the movement of the nozzle body 6 that moves in the Y-axis direction Y, the Z-axis direction Z1, and around the axis 01 line parallel to the X-axis direction X and around the axis 02 line parallel to the Y-axis direction Y is calculated under the same shoe last. By making various changes, it is possible to automatically perform the gluing work corresponding to each size.

〔Effect of the invention〕

As described above, the present invention moves the nozzle body relative to the processing surface by selecting several points on the coordinates modeled after a shoe last, in the X-axis direction as a direction perpendicular to the longitudinal direction of the workpiece, and in the longitudinal direction. Information about the working path of the nozzle body in a total of five axes around the Y-axis direction, the X-axis direction, the Z-axis direction perpendicular to the Y-axis direction, and axes parallel to the X-axis direction or the Y-axis direction, respectively. The control motor is controlled and driven based on the machining data that is stored in the computer, and the nozzle body is used as the workpiece to create machining conditions such as plane curves, peaks and troughs, and slopes at the outer edge of the upper surface of the shoe body. It is possible to move finely and responsively according to the
Highly accurate gluing can be performed on the shoe body as a workpiece with little movement error.

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