Description

Technical Field

[0001] The present invention relates to the technical field of clothing production, and particularly to an automatic shoe groove scribing device and method. Background Art

[0002] In the footwear manufacturing industry, shoe groove scribing is a crucial process step, and its quality directly affects the appearance and quality of shoes. The traditional shoe groove scribing method mainly relies on manual operation. Workers hold scribing tools and scribe along the shoe groove one by one. However, this manual scribing method has many drawbacks.

[0003] On the one hand, manual operation is inefficient and difficult to meet the needs of large-scale production. With the continuous expansion of the footwear market and the increasing production order volume, the speed of manual scribing far lags behind the production rhythm, resulting in an extended production cycle and increased production costs. On the other hand, the quality of manual scribing is difficult to guarantee. Due to factors such as the technical level, operation proficiency, and fatigue level of workers, it is very difficult to control the thickness uniformity of the scribed lines, and problems such as uneven line thickness and line skew are likely to occur, seriously affecting the overall quality of the shoes.

[0004] In addition, manual scribing also has certain safety hazards. During long-term operation, workers are prone to inattentiveness due to fatigue, thus triggering safety accidents. Moreover, manual scribing requires workers to maintain the same posture for a long time, which is likely to cause occupational diseases and harm the physical health of workers. Therefore, it is of great practical significance to develop a device that can achieve automatic, efficient, and high-quality shoe groove scribing. Summary of the Invention

[0005] An object of the present invention is to provide an automatic shoe groove scribing device to achieve efficient, stable, and economical shoe groove scribing.

[0006] To achieve the above object, the technical solution adopted by the present invention is: to provide an automatic shoe groove scribing device, the automatic shoe groove scribing device includes: A conveying device, on which a plurality of conveying platforms are arranged, and a conveying power unit for driving the linear movement of the conveying platforms; A rotating mechanism, which is installed on the conveying platform, and the rotating shaft of the rotating mechanism is horizontally arranged; the shoe body to be scribed is installed on the rotating shaft; The line-drawing part, the line-drawing part includes a mounting frame and a line-drawing rod. The mounting frame is fixed on the machine frame. The line-drawing rod is vertically slidably arranged on the mounting frame in the vertical direction of the horizontal plane. The line-drawing rod is aligned with the shoe groove of the shoe body. The line-drawing rod is designed with a hollow structure. The inside of the line-drawing rod is filled with ink for line-drawing. The bottom of the line-drawing rod is provided with a line-drawing head. The line-drawing head is closely attached to the shoe groove of the shoe body. When the rotating mechanism drives the shoe body to rotate, the line-drawing head draws a line along the shoe groove of the shoe body; The control part, the control part is arranged on the rotating mechanism and the mounting frame. The control part is electrically connected to the conveying power part and the rotating mechanism to control the operation of the conveying power part and the rotating mechanism.

[0007] In one embodiment, the line-drawing head has a hollow conical structure. The bottom of the tip of the line-drawing head is provided with an ink outlet. A freely rotatable steel ball is arranged on the ink outlet. The bottom end of the steel ball protrudes from the ink outlet.

[0008] In one embodiment, it further includes a force-applying ring. The force-applying ring is fixed on the line-drawing rod. The force-applying ring is used to apply a constant downward pressure to the line-drawing rod; when the bottom of the force-applying ring is closely attached to the mounting frame, the line-drawing rod is in the lowest position state.

[0009] In one embodiment, the mounting frame is provided with a sliding hole. The diameter of the sliding hole is larger than the outer diameter of the line-drawing rod. A plurality of freely rotatable rolling balls are embedded in the sliding hole. The rolling balls are closely attached to the line-drawing rod.

[0010] In one embodiment, the rotating mechanism includes: An L-shaped mounting plate, the bottom plate of the L-shaped mounting plate is fixed on the conveying platform; A rotating power part, the rotating power part is arranged on the L-shaped mounting plate. The axis of the rotating shaft of the rotating power part is vertically intersecting with the axis of the line-drawing rod; A shoe mold, the shoe mold is fixed on the rotating shaft of the rotating power part. The shoe mold is provided with a mounting groove for mounting and fixing the shoe body. The shoe body is mounted in the mounting groove of the shoe mold.

[0011] In one embodiment, the outer shape of the mounting groove is the same as the outer shape of the shoe body.

[0012] In one embodiment, the control part includes: An infrared sensor, the infrared sensor is arranged on the top plate of the L-shaped mounting plate; An identification mark, the identification mark is arranged on the mounting frame. The identification mark is used in cooperation with the infrared sensor; A programmable control module, which is electrically connected to the infrared sensor, the rotation power unit, and the conveying power unit, and the programmable control module controls the operation of the rotation power unit and the conveying power unit according to the information sent by the infrared sensor.

[0013] Another object of the present invention is to provide a method for automatically drawing lines on a shoe groove. The method for automatically drawing lines on a shoe groove includes the following steps: S1. Mount and fix the shoe body on the shoe mold, and use the mounting groove on the shoe mold to position the shoe body so that the shoe groove and the line-drawing rod are in the same plane; S2. The conveying device transports the rotating mechanism and the shoe body thereon. When the infrared sensor senses the identification mark on the mounting frame, the infrared sensor transmits the signal to the programmable control module, and the programmable control module controls the conveying power unit to stop immediately according to the signal, so that the shoe body stays in the line-drawing area where the line-drawing rod is located; S3. The programmable control module controls the rotation power unit to rotate one week, and keeps the linear velocity of the contact area between the shoe body and the line-drawing head uniform and unchanged, and completes the operation of drawing the shoe groove; S4. After the rotation power unit completes the rotation action, the programmable control module controls the conveying power unit to continue to operate; S5. Repeat steps S2 - S4 to draw lines on the next shoe body.

[0014] In one or more of the above technical solutions in the embodiments of the present invention, there are at least the following technical effects or advantages: The automatic shoe groove line-drawing device and method of the present invention precisely control the work of the rotating mechanism and the conveying power unit through the control unit. The conveying device can accurately transport the rotating mechanism and the shoe body thereon to the line-drawing area (i.e., directly below the line-drawing rod), stop, and control the rotating mechanism to drive the shoe body to rotate for line-drawing. After the line-drawing is completed, the control unit controls the rotating mechanism to stop operating, and at the same time starts the conveying power unit. Until the shoe body on the next rotating mechanism moves to the line-drawing area, the above actions are repeated again for line-drawing. This automated continuous line-drawing method greatly improves production efficiency, can meet the needs of large-scale production, effectively shortens the production cycle, and reduces production costs.

[0015] Moreover, during the line-drawing process, when the shoe body is mounted on the rotating mechanism, its bottom surface is perpendicular to the horizontal plane, and the line-drawing rod is vertically slidably arranged on the mounting frame with respect to the horizontal plane. When the shoe body rotates, the line-drawing head at the bottom of the line-drawing rod presses against the shoe groove of the shoe body under its own gravity, and the line-drawing rod slides up and down with the height fluctuation of the shoe groove caused by the rotation of the shoe body, so that the line-drawing head can relatively move around the shoe groove when the shoe body rotates, thereby drawing lines on the shoe groove. At the same time, the line-drawing pressure exerted by the line-drawing head on the shoe groove is the gravity of the line-drawing rod (ignoring the internal ink consumption), and its magnitude is basically unchanged. Therefore, the thickness of the lines drawn by the line-drawing head (related to the line-drawing pressure of the line-drawing head) is basically the same, making the thickness of the shoe groove lines uniform, greatly improving the appearance aesthetics and quality of the shoes.

[0023] Please refer to Figures 1 to 3 , an automatic shoe groove line drawing device is provided in an embodiment of the present application, which includes a conveying device 1, a rotating mechanism 2, a line drawing part 3, and a control part 4. Among them, a plurality of conveying platforms 11 are arranged on the conveying device 1, and a conveying power part for driving the linear movement of the conveying platform 11. The rotating mechanism 2 is installed on the conveying platform 11, and the rotating shaft of the rotating mechanism 2 is horizontally arranged; the shoe body 5 to be line drawn is installed on the rotating shaft. The line drawing part 3 includes a mounting frame 31 and a line drawing rod 32. The mounting frame 31 is fixed to the machine frame, and the line drawing rod 32 is vertically slidably arranged on the mounting frame 31 in the horizontal plane. The line drawing rod 32 is aligned with the shoe groove of the shoe body 5. The line drawing rod 32 is designed with a hollow interior, and the interior of the line drawing rod 32 is filled with the ink used for line drawing. A line drawing head 321 is arranged at the bottom of the line drawing rod 32, and the line drawing head 321 closely adheres to the shoe groove of the shoe body 5. When the rotating mechanism 2 drives the shoe body 5 to rotate, the line drawing head 321 draws a line along the shoe groove of the shoe body 5. The control part 4 is arranged on the rotating mechanism 2 and the mounting frame 31, and the control part 4 is electrically connected to the conveying power part and the rotating mechanism 2 to control the operation of the conveying power part and the rotating mechanism 2.

[0024] In the present invention, the control unit 4 controls the rotating mechanism 2 and the conveying power unit, so that the conveying device 1 can accurately transfer the rotating mechanism 2 and the shoe body 5 thereon to the drawing area (i.e., directly below the drawing rod 32) and then stop (as Figure 2 shown), and controls the rotating mechanism 2 to drive the shoe body 5 to rotate. Since the bottom surface of the shoe body 5 is perpendicular to the horizontal plane when the shoe body 5 is installed on the rotating mechanism 2, and the drawing rod 32 is vertically slidably arranged on the mounting bracket 31 perpendicular to the horizontal plane. Therefore, when the shoe body 5 rotates, the drawing head 321 at the bottom of the drawing rod 32 closely adheres to the shoe groove of the shoe body 5 under its own action, and the drawing rod 32 slides up and down as the shoe body 5 rotates due to the height fluctuation of the shoe groove ( Figure 3 is a schematic diagram of drawing when the shoe body 5 rotates 90°, at this time the drawing rod 32 slides up to the top position), so that the drawing head 321 can move relative to the shoe groove around the shoe groove when the shoe body 5 rotates, and then draw a line on the shoe groove. Its principle is similar to the generation method. When the drawing is completed, the control unit 4 controls the rotating mechanism 2 to stop operating, and at the same time starts the conveying power unit until the shoe body 5 on the next rotating mechanism 2 moves to the drawing area, and then repeats the above actions to draw a line again, thus realizing automatic continuous drawing. And because during the drawing process, the drawing pressure exerted by the drawing head 321 on the shoe groove is the gravity of the drawing rod 32 (ignoring the internal ink consumption), and its magnitude is basically unchanged, so that the thickness of the line drawn by the drawing head 321 (related to the drawing pressure of the drawing head 321) is basically the same, making the thickness of the shoe groove line uniform.

[0025] In one embodiment, the drawing head 321 has a hollow conical structure. An ink outlet is provided at the bottom of the tip of the drawing head 321, and a freely rotatable steel ball 322 is provided on the ink outlet. The bottom end of the steel ball 322 protrudes from the ink outlet. When drawing a line, due to the relative movement between the bottom of the tip of the drawing head 321 and the shoe groove of the shoe body 5, the frictional force between the two makes the steel ball 322 rotate. The drawing rod 32 and the drawing head 321 are filled with ink. While the steel ball 322 rotates, the ink in the drawing head 321 is taken out and engraved in the shoe groove, realizing the drawing function. And when it is in the non-drawing state, since the steel ball 322 will not rotate, the ink in the drawing head 321 will not be taken out, so that the ink will not flow out and be wasted in the non-drawing state, saving costs.

[0026] In one embodiment, it further includes a force-applying ring 33. The force-applying ring 33 is fixed on the drawing rod 32. The force-applying ring 33 is used to apply a constant downward pressure to the drawing rod 32; when the bottom of the force-applying ring 33 closely adheres to the mounting bracket 31, the drawing rod 32 is in the lowest position state. The weight of the force-applying ring 33 can be adjusted according to the actual drawing requirements. The force-applying ring 33 can increase the drawing pressure exerted by the drawing head 321 on the shoe groove during drawing to adjust the thickness of the drawn line.

[0027] Optionally, an elastic member (such as a spring, a shrapnel, etc.) can also be provided inside the drawing head 321. One end of the elastic member is fixed inside the drawing head 321, and the other end of the elastic member abuts against the steel ball 322. When the drawing pressure increases, the elastic member is compressed and retracts, causing the steel ball 322 to also retract towards the inside of the drawing head 321. As a result, the gap between the steel ball 322 and the edge of the ink outlet becomes larger, making the ink inside the drawing head 321 flow out more easily, thereby increasing the thickness of the drawn line. Conversely, when the drawing pressure decreases, the elastic member rebounds, causing the steel ball 322 to approach the ink outlet, resulting in a smaller gap between the steel ball 322 and the edge of the ink outlet, making the ink inside the drawing head 321 more difficult to flow out, and causing the thickness of the drawn line to become smaller. Thus, the thickness of the drawn line can be adjusted according to the magnitude of the drawing pressure.

[0028] As Figure 5 shown, in one embodiment, a sliding hole is provided on the mounting bracket 31. The diameter of the sliding hole is larger than the outer diameter of the drawing rod 32. A plurality of freely rotatable balls 311 are embedded in the sliding hole, and the balls 311 are in close contact with the drawing rod 32. Specifically, the balls 311 are evenly distributed annularly along the inner wall of the sliding hole, and the number is not less than 4. By rolling friction, the resistance between the drawing rod 32 and the mounting bracket 31 is reduced, ensuring the vertical sliding accuracy. Therefore, by providing the balls 311, the friction between the drawing rod 32 and the mounting bracket 31 is reduced, thereby reducing the wear rate of the drawing rod 32 and increasing the service life of the device. And reducing the friction between the drawing rod 32 and the mounting bracket 31 makes the drawing force during drawing less affected by friction, facilitating the control of the thickness of the drawn line.

[0029] In one embodiment, the rotating mechanism 2 includes an L-shaped mounting plate 21, a rotating power unit 22, and a shoe mold 23. The bottom plate of the L-shaped mounting plate 21 is fixed on the conveying platform 11. The rotating power unit 22 is arranged on the L-shaped mounting plate 21, and the axis of the rotating shaft of the rotating power unit 22 is perpendicular to and intersects with the axis of the drawing rod 32. The shoe mold 23 is fixed on the rotating shaft of the rotating power unit 22, and an installation groove for installing and fixing the shoe body 5 is provided on the shoe mold 23. The shoe body 5 is installed in the installation groove of the shoe mold 23. The L-shaped mounting plate 21 is installed on the conveying platform 11 through threaded parts. When drawing a line, the rotating power unit 22 (specifically, a stepping motor) works and drives the shoe mold 23 to rotate, thereby causing the shoe body 5 to rotate for drawing a line.

[0030] In one embodiment, the outer shape of the installation groove is the same as the outer shape of the shoe body 5. As Figure 4 shown, by setting the installation groove to have the same outer shape as the shoe body 5, the shoe body 5 is more stable when installed in the installation groove, and the installation groove can play a role in positioning the shoe body 5, improving the drawing accuracy.

[0031] In one embodiment, the control unit 4 includes an infrared sensor, an identification marker 42, and a programmable control module. Among them, the infrared sensor is disposed on the top plate of the L-shaped mounting plate 21. The identification marker 42 is disposed on the mounting bracket 31, and the identification marker 42 is used in cooperation with the infrared sensor. The programmable control module is electrically connected to the infrared sensor, the rotation power unit 22, and the conveying power unit, and the programmable control module controls the operation of the rotation power unit 22 and the conveying power unit according to the information sent by the infrared sensor.

[0032] When the conveying device 1 transports the rotating device and the infrared sensor thereon to the drawing area, at this time, the infrared sensor senses the identification marker 42 on the mounting bracket 31, and then controls the conveying power unit to stop operating through the programmable control module, so that the rotating mechanism 2 stays in the drawing area. And, the programmable control module controls the rotation power unit 22 to rotate for drawing a line.

[0033] Another object of the present invention is to provide an automatic shoe groove drawing method, and the automatic shoe groove drawing method includes the following steps: S1. Mount and fix the shoe body 5 on the shoe mold 23, and use the mounting groove on the shoe mold 23 to position the shoe body 5 so that the shoe groove and the drawing rod 32 are in the same plane; S2. The conveying device 1 transports the rotating mechanism 2 and the shoe body 5 thereon. When the infrared sensor senses the identification marker 42 on the mounting bracket 31, the infrared sensor transmits a signal to the programmable control module, and the programmable control module controls the conveying power unit to stop immediately according to the signal, so that the shoe body 5 stays in the drawing area where the drawing rod 32 is located; S3. The programmable control module controls the rotation power unit 22 to rotate one week, and keeps the linear velocity of the contact area between the shoe body 5 and the drawing head 321 uniform and unchanged, and completes the shoe groove drawing action; S4. After the rotation power unit 22 completes the rotation action, the programmable control module controls the conveying power unit to continue operating; S5. Repeat steps S2 - S4 to draw the next shoe body 5.

[0034] Among them, in step S3, by keeping the linear velocity of the contact area between the shoe body 5 and the drawing head 321 uniform and unchanged, the specific method can preset the rotational angular velocity in each rotational angle interval according to the shape of the shoe groove of the shoe body 5 and the positional relationship of the rotation center, so that when drawing a line, the relative movement speed between the drawing head 321 and the shoe groove remains uniform and unchanged, so as to improve the uniformity of the drawing width and improve the drawing quality.

[0035] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
