Description

Technical Field

[0001] The present invention relates to the technical field of shoulder strap machines, and particularly to a fully automatic shoulder strap machine that can automatically feed buttons and automatically install buttons. Background Art

[0002] In related technologies, the length of an underwear shoulder strap is generally adjusted by a shoulder button. The models of the shoulder buttons include figure-eight buttons, figure-nine buttons, or figure-zero buttons. Currently, in the market, the assembly between the shoulder button and the shoulder strap is produced by semi-automatic equipment. The structures of the equipment commonly found in the market are more or less the same. The shoulder buttons are fed by a vibrating bowl feeder, vertically dropped, and pushed to the position where the strap needs to be threaded by a cylinder. This structure is relatively complex, and it is easy for the buckle to get stuck or the shoulder button to become detached, resulting in low reliability and thus low production efficiency.

[0030] The following embodiments are used to illustrate the present invention, but the present invention is not limited by these embodiments. Modifying the specific implementation manners of the present invention or making equivalent replacements for some technical features without departing from the spirit of the present invention shall be covered within the scope of the technical solutions claimed by the present invention.

[0031] Embodiment 1: As Figures 1 to 6 shown, this embodiment provides a fully automatic shoulder strap machine, including a button feeding mechanism 100, an automatic button installing mechanism 200, and a control system 300. The button feeding mechanism 100 and the automatic button installing mechanism 200 are connected in sequence, and the control system 300 is electrically connected to the button feeding mechanism 100 and the automatic button installing mechanism 200 respectively, wherein;

[0032] The button feeding mechanism 100 includes a vibrating disk feeding assembly, a button feeding channel 1, a button pressing assembly 2, and a switch assembly 3. The output end of the vibrating disk feeding assembly is connected to the input end of the button feeding channel 1. The button feeding channel 1 is arranged to slope downwards from its input end to the output end. The switch assembly 3 is arranged at the output end of the button feeding channel 1 to open or close the output end of the button feeding channel 1. The button pressing assembly 2 is arranged above the button feeding channel 1 to press the shoulder button 4 located in the button feeding channel 1 and to be output;

[0033] The automatic button installing mechanism 200 includes a button feeding track 5, a clamping belt assembly 6, a belt pushing assembly 7, a downward belt threading assembly 8, and an upward belt threading assembly 9. The input end of the button feeding track 5 is connected to the output end of the button feeding channel 1. A button installing station 500 is arranged on the button feeding track 5. The clamping belt assembly 6 is arranged on one side of the button installing station 500 to clamp the shoulder strap located in the button installing station 500 and to send the shoulder strap with the button installed to the sewing mechanism 10. The downward belt threading assembly 8 is arranged above the button installing station 500 to thread the shoulder strap downwards through the shoulder button 4 located in the button installing station 500. The upward belt threading assembly 9 is arranged below the button installing station 500 to thread the shoulder strap upwards through the shoulder button 4 located in the button installing station 500. The belt pushing assembly 7 is arranged on the other side of the button installing station 500 to push the end of the shoulder strap that has completed downward and upward button threading towards the clamping belt assembly 6 and to be clamped by the clamping belt assembly 6.

[0034] The fully automatic shoulder strap machine provided by this embodiment has a relatively simple structure, can complete automatic button feeding and automatic button installation, effectively improves production efficiency, and ensures product quality.

[0035] Moreover, the structure of the buckle feeding mechanism is relatively simple, the shoulder buckle is not easily detached, and the reliability is relatively high. The automatic buckle mounting mechanism 200 can improve the buckle mounting efficiency and ensure the product quality. Specifically, by using the automatic buckle mounting mechanism provided in this embodiment, the operations of buckle feeding, shoulder strap threading, and sewing can be automatically completed. Workers only need to place the end of the shoulder strap in the buckle mounting station 500, which effectively reduces the working intensity of workers, improves the working efficiency, avoids reducing the error rate of manual work, and ensures the product quality.

[0036] Specifically, the control system 300 controls the operations of the vibrating plate feeding assembly, the buckle pressing assembly 2, and the switch assembly 3. The vibrating plate feeding assembly is used to provide the shoulder buckle 4. The vibrating plate feeding assembly sends the shoulder buckle 4 to the buckle feeding channel 1. At this time, the switch assembly 3 is in the closed state, that is, the switch assembly 3 closes the output end of the buckle feeding channel 1, and the shoulder buckle 4 stays in the buckle feeding channel 1. When the switch assembly 3 receives an instruction to output the shoulder buckle 4, the switch assembly 3 opens the output end of the buckle feeding channel 1. Since the buckle feeding channel 1 is inclined downward from its input end to the output end, at this time, the shoulder buckle 4 will be output downward. At the same time, the buckle pressing assembly 2 works to press the shoulder buckle 4 located in the buckle feeding channel 1 to be output, and only allows 1 shoulder buckle 4 to be output from the buckle feeding channel 1. After the output of the shoulder buckle 4 is completed, the switch assembly 3 receives an instruction and closes the output end of the buckle feeding channel 1, and at the same time, the buckle pressing assembly 2 releases. At this time, the shoulder buckle 4 in the buckle feeding channel 1 will move forward until the next time the shoulder buckle 4 needs to be output again. Through the cooperation of the buckle feeding channel 1 and the buckle pressing assembly 2 provided, the shoulder buckle 4 is not easily detached, and the reliability is relatively high, ensuring the normal, stable, and reliable operation of the equipment.

[0037] In this embodiment, the buckle feeding channel 1 includes a first base 11 and a second base 12. A convex portion 110 is provided on one side of the first base 11. The second base 12 is disposed on the other side of the first base 11. A first channel 101 is formed between the convex portion 110 and the second base 12. A second channel 102 communicating with the first channel 101 is provided on the side of the first channel 101 and on the convex portion 110. The first channel 101 and the second channel 102 are combined to form the buckle feeding channel 1. Its structure is simple, the design is reasonable and ingenious. By providing the second channel 102, the position and movement direction of the shoulder buckle 4 can be limited, avoiding the occurrence of the situation where the shoulder buckle 4 is detached, and to a certain extent, ensuring that the buckle feeding mechanism can stably convey the shoulder buckle 4.

[0038] Further, the buckle assembly 2 includes a first driving device 21 and a pressing plate 22, wherein the driving end of the first driving device 21 is connected to the pressing plate 22 for driving the pressing plate 22 to move up and down, and the lower end of the pressing plate 22 can be inserted into the first channel 101 to press the shoulder buckle 4 to be output in the first channel 101. The structure is simple, and the design is reasonable and ingenious. When the switch assembly 3 receives an instruction to output the shoulder buckle 4, the switch assembly 3 opens the output end of the buckle delivery channel 1. Since the buckle delivery channel 1 is tilted downward from its input end to the output end, the shoulder buckle 4 will be output downward at this time. At the same time, the working pressing plate 22 of the buckle assembly 2 will press the shoulder buckle 4 to be output in the buckle delivery channel 1, and only one shoulder buckle 4 is allowed to be output from the buckle delivery channel 1. When the output of the shoulder buckle 4 is completed, the switch assembly 3 closes the output end of the buckle delivery channel 1 after receiving the instruction, and the pressing plate 22 retreats at the same time. At this time, the shoulder buckle 4 in the buckle delivery channel 1 will move forward to be supplemented until the shoulder buckle 4 is needed to be output next time.

[0039] Furthermore, the switch assembly 3 includes a second driving device 31 and a switch plate 32. A mounting groove 111 is provided on the first base 11 or the second base 12 to allow the switch plate 32 to move up and down. A notch 320 is provided on the switch plate 32 to match the button delivery channel 1. The driving end of the second driving device 31 is connected to the switch plate 32 to drive the switch plate 32 to move up and down. When the switch assembly 3 receives an instruction to output the shoulder button 4, the switch plate 32 moves so that the notch 320 is connected to the button delivery channel 1. Since the button delivery channel 1 is tilted downward from its input end to the output end, the shoulder button 4 is output downward through the notch 320 in the button delivery channel 1. When the output of the shoulder button 4 is completed, the switch assembly 3 receives an instruction, and the switch plate 32 moves so that the notch 320 is staggered with the button delivery channel 1. At this time, the shoulder button 4 in the button delivery channel 1 will move forward to supplement and be blocked by the switch plate 32 until the shoulder button 4 is output next time.

[0040] In this embodiment, a protective component 13 is provided at the end of the buckle delivery channel 1 to prevent the shoulder buckle 4 from popping out. The structure thereof is relatively simple, the shoulder buckle is not easy to be detached, and the reliability is relatively high.

[0041] Furthermore, the protective assembly 13 includes an upper protective plate 131 arranged above the end of the buckle delivery channel 1, and a left protective plate 132 and a right protective plate 133 arranged on the outer periphery of the end of the buckle delivery channel 1. It has a simple structure and a reasonable and ingenious design. The above can prevent the shoulder buckle 4 from detaching or popping out, thereby ensuring the stability and reliability of the buckle delivery mechanism.

[0042] In this embodiment, a blowing component 14 is provided on one side below the button-fastening station 500. The airflow blown by the blowing component 14 can make the end of the shoulder strap passing downward through the shoulder button 4 horizontally placed, and the upward strap-passing component 9 passes the horizontally placed end of the shoulder strap upward through the shoulder button 4 located within the button-fastening station 500.

[0043] The working process of the automatic button-fastening mechanism provided in this embodiment is described as follows:

[0044] 1. The button-feeding mechanism 100 sends the shoulder button to the button-fastening station 500 through the button-feeding track 5;

[0045] 2. Place the end of the shoulder strap within the button-fastening station 500 and clamp and fix it with the clamping component 6;

[0046] 3. The downward strap-passing component 8 acts to pass the shoulder strap downward through the first shoulder-button hole of the shoulder button 4 located within the button-fastening station 500;

[0047] 4. The blowing component 14 acts to blow out an airflow to make the end of the shoulder strap horizontally placed;

[0048] 5. The upward strap-passing component 9 acts to pass the horizontally placed end of the shoulder strap upward through the second shoulder-button hole of the shoulder button 4 located within the button-fastening station 500;

[0049] 6. The clamping component 6 releases, and the strap-pushing component 7 acts to push the end of the shoulder strap that has completed passing through the button downward and upward to the clamping component 6 and clamp it with the clamping component 6;

[0050] 7. The clamping component 6 acts to send the shoulder strap that has completed button-fastening to the sewing mechanism 10;

[0051] 8. The sewing mechanism 10 acts to complete the assembly of the shoulder strap and the shoulder button.

[0052] In this embodiment, the width of the button-feeding track 5 and / or the button-fastening station 500 is adjustable. Its structure is simple. Through the above settings, the automatic button-fastening mechanism provided in this embodiment can be applicable to shoulder buttons of different widths, effectively improving its versatility and reducing user costs.

[0053] Preferably, the downward strap-passing component 8 includes a downward driving device 801 and a first insertion rod 802. The downward driving device 801 is connected to the first insertion rod 802, and the first insertion rod 802 is used to pass the shoulder strap downward through the shoulder button 4 located within the button-fastening station 500;

[0054] The upward strap-passing component 9 includes an upward driving device 901 and a second insertion rod 902. The upward driving device 901 is connected to the second insertion rod 902, and the second insertion rod 902 is used to pass the shoulder strap upward through the shoulder button 4 located within the button-fastening station 500.

[0055] In this embodiment, both the downward driving device 801 and the upward driving device 901 adopt air cylinders. Through the cooperation of the air cylinders with the first insertion rod 802 and the second insertion rod 902, it is beneficial to pass the shoulder strap downward or upward through the shoulder buckle, and the work is stable and reliable.

[0056] Furthermore, the strap pushing assembly 7 includes a strap pushing driving device 701 and a pushing plate 702. The strap pushing driving device 701 is connected to the pushing plate 702, and the pushing plate 702 is used to push the end of the shoulder strap that has completed passing through the buckle downward and upward towards the strap clamping assembly 6 and be clamped by the strap clamping assembly 6. In this embodiment, the strap pushing driving device 701 also adopts an air cylinder. By using the pushing plate 702, it is convenient to push the end of the shoulder strap flat, press the shoulder strap and the shoulder buckle tightly, and then push the end of the shoulder strap towards the strap clamping assembly 6 and be clamped by the strap clamping assembly 6, effectively ensuring the tightness of the connection between the shoulder strap and the shoulder buckle.

The fixed clamping member 602 is arranged on the moving device 601, and the movable clamping member 603 cooperates with the fixed clamping member 602 to clamp the shoulder strap. Through the moving device 601, the shoulder strap that has completed buttoning can be sent from the buttoning station 500 to the sewing mechanism 10. Its structure is simple and the design is reasonable. By arranging the fixed clamping member 602 and the movable clamping member 603 on the moving device 601, the moving device 601 sends the buttoned shoulder strap clamped by the fixed clamping member 602 and the movable clamping member 603 to the sewing mechanism 10, avoiding loosening or even unbuttoning during this process, and effectively improving the buttoning quality of the automatic buttoning mechanism.

[0058] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
