Description

Technical Field

[0001] The invention belongs to the technical field of sewing equipment and relates to a rotating mechanism in an automatic button feeding device. Background Art

[0002] When sewing buttons, a clamping mechanism is generally required to clamp the button, which is then rotated by a rotating mechanism to deliver the button to the button sewing machine. Chinese patent application number 201621007038.2 discloses a button positioning and conveying mechanism, which includes a support plate, a lifting cylinder, a stepper motor, and a stepper motor fixing plate. The stepper motor is fixed to the stepper motor fixing plate, the lifting cylinder is fixed to the support plate, and the push rod of the lifting cylinder drives the stepper motor fixing plate to move up and down. A swing arm assembly is fixed to the output shaft of the stepper motor, and the swing arm assembly is provided with a button positioning claw.

[0003] The shortcoming of the above-mentioned button positioning and transmission mechanism is that there is no structure for positioning the swing arm assembly, which makes it easy for deviations to occur when obtaining buttons. Summary of the Invention

[0004] In view of the above problems existing in the prior art, the present invention provides a rotating mechanism in an automatic button feeding device. The technical problem to be solved by the present invention is: how to align the clamping mechanism with the button feeding channel.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A rotating mechanism in an automatic button feeding device, the rotating mechanism includes a mounting seat, a swing arm is hinged on the mounting seat, and a driving member for driving the swing arm to rotate is provided on the mounting seat. It is characterized in that a positioning part is provided on the mounting seat, and a positioning rod is connected to the swing arm, and the positioning rod can abut against the positioning part.

[0007] Its working principle is: in this rotating mechanism, the swing arm is hinged on the mounting seat, and the button clamping mechanism is installed on the swing arm. When the driving member drives the swing arm to rotate a certain angle, the positioning rod 1 abuts against the positioning part, and the swing arm stops rotating. At this time, the clamping arm on the clamping mechanism is just aligned with the feeding channel. The positioning rod 1 and the positioning part of the rotating mechanism form a positioning structure, so that the clamping mechanism can swing to the same position every time, so that the clamping arm can be accurately aligned with the feeding channel, avoiding deviation when clamping the buttons, and ensuring accurate clamping of the buttons.

[0008] In the above-mentioned rotating mechanism of the automatic button feeding device, a second positioning rod is connected to the positioning portion, and the second positioning rod can abut against the inner end portion of the swing arm.

[0009] The button clamping mechanism is installed on the outer end of the swing arm. When the driving member drives the swing arm to rotate in the opposite direction for a certain angle, the positioning rod 2 abuts against the inner end of the swing arm, and the swing arm stops rotating. At this time, the clamping arm on the clamping mechanism is just aligned with the button sewing mechanism of the button sewing machine, and the button clamped by the clamping arm is accurately sent to the place on the clothes where the button is to be sewn. The positioning rod 2 and the positioning part of the rotating mechanism form another positioning structure, so that the clamping mechanism can be accurately aligned with the button sewing mechanism.

[0010] In the rotating mechanism of the above-mentioned automatic button feeding device, the positioning part is a limit block, the mounting seat is provided with a limit groove, the limit groove is inclined, the limit block is located in the limit groove and can slide in the limit groove, the limit block is provided with a strip groove, a bolt is passed through the strip groove, the bolt and the strip groove can slide relative to each other, and the bolt fastens the limit block to the limit groove with a thread. In this structure, when the bolt is loosened, the limit block can slide in the limit groove, so that the position of the limit block and the positioning rod 1 or the positioning rod 2 can be adjusted according to the position of the positioning rod 1 or the positioning rod 2, so that the limit block can fully contact the positioning rod 1 or the positioning rod 2, and the positioning is more accurate. After the position is adjusted, the bolt can be tightened to conveniently fix the limit block.

[0011] As another embodiment, the positioning portion may also be a positioning plate or a boss, etc., and its shape is not limited.

[0012] In the aforementioned rotating mechanism of the automatic button-feeding device, the inner end of the swing arm has a curved surface, and the second positioning rod is capable of abutting against the curved surface. After the swing arm swings to a certain angle, the curved surface and the second positioning rod are constantly abutting against each other as the swing arm moves toward the button-sewing mechanism, thereby reducing shaking of the swing arm during swinging and improving its stability.

[0013] In the rotating mechanism of the automatic button feeding device, the inner end of the swing arm has a first abutment surface, which is a plane. The second positioning rod can abut against the first abutment surface. The first abutment surface can abut against the second positioning rod more fully, thereby achieving a better positioning effect.

[0014] In the rotating mechanism of the automatic button feeding device, the top of the positioning portion has a second abutment surface, which is a plane. The positioning rod 1 can abut against the second abutment surface. The plane abutment surface 2 can abut against the positioning rod 1 more fully, thereby achieving a better positioning effect.

[0015] In the aforementioned rotating mechanism of the automatic button feeding device, a fixed plate is slidably connected to the swing arm, and a second driving member capable of driving the fixed plate is fixed to the swing arm. In this structure, the button clamping mechanism is fixed to the fixed plate. When the feed channel is located at different heights on the frame, sliding the fixed plate can also adjust the position of the clamping arm on the clamping mechanism so that the clamping arm is aligned with the feed channel, thereby improving adaptability.

[0016] In the rotating mechanism of the above-mentioned automatic button feeding device, a push rod is fixed on the fixed plate, and a buffer pad is provided on the swing arm, and the push rod can abut against the buffer pad.

[0017] The buffer pad and the push rod form a limit buffer structure, which can limit the fixed plate and prevent the fixed plate from moving beyond the limit. The buffer pad is made of elastic material. When the push rod collides with it, it plays a buffering role to prevent the push rod from being damaged due to collision. At the same time, it has a certain reset function.

[0018] In the aforementioned rotating mechanism of the automatic button feeding device, the first positioning rod is a screw rod or a shaft pin, the screw rod being threadedly connected to the swing arm or the shaft pin being inserted and fixed to the swing arm, and the second positioning rod is a screw rod or a shaft pin, the screw rod being threadedly connected to the positioning portion or the shaft pin being inserted and fixed to the positioning portion. When the first positioning rod is a bolt, rotating the first screw rod can adjust the distance between the first screw rod and the positioning portion as needed, ensuring sufficient contact between the first positioning rod and the positioning portion, thereby achieving more precise positioning.

[0019] Similarly, when the positioning rod 2 is bolt 2, rotating the screw 2 can adjust the distance between the screw 2 and the inner end of the swing arm as needed, so that the positioning rod 2 and the inner end of the swing arm can fully contact each other, thereby improving the accuracy of positioning.

[0020] In the aforementioned rotating mechanism of an automatic button-feeding device, the first driving member is a first motor, the output shaft of which is connected to the rotating shaft of the swing arm. The second driving member is a pneumatic cylinder or a linear motor, the piston rod of which or the output shaft of which is connected to the fixed plate. A guide rail is fixed to the swing arm, and a slider is fixed to the fixed plate, which is slidably connected to the guide rail. In this structure, the first motor drives the swing arm to rotate, causing the button clamping mechanism on the swing arm to align with the feeding channel or causing the button clamping mechanism to grasp a button and then deliver it to the button sewing mechanism.

[0021] The guide rail and the slider form a guide rail slider structure, which can greatly improve the stability of the fixed plate when it moves.

[0022] As another embodiment, the first driving member is a combination of the second motor and a gear assembly.

[0023] Compared with the prior art, the advantages of the present invention are as follows:

[0024] 1. The positioning rod and the positioning part of the rotating mechanism form a positioning structure, so that the clamping mechanism can swing to the same position every time, so that the clamping arm can accurately align with the feeding channel, avoiding deviation when clamping the buttons, and ensuring accurate clamping of the buttons.

[0025] 2. The second positioning rod and the positioning part of the rotating mechanism form another positioning structure, so that the clamping mechanism can be accurately aligned with the button mechanism;

[0026] 3. A fixed plate is slidably connected to the swing arm of the rotating mechanism. The sliding fixed plate can adjust the position of the clamping arm on the clamping mechanism so that the clamping arm is aligned with the feeding channel, thereby improving adaptability.

DETAILED DESCRIPTION

[0034] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0035] like Figure 1 and 2As shown, the rotating mechanism includes a mounting base 1, a swing arm 2 is hinged on the mounting base 1, a driving member 3 for driving the swing arm 2 to rotate is provided on the mounting base 1, a positioning portion 4 is provided on the mounting base 1, and a positioning rod 5 is connected to the swing arm 2, and the positioning rod 5 can be abutted against the positioning portion 4.

[0036] In this rotating mechanism, the swing arm 2 is hinged on the mounting base 1, and the button clamping mechanism 25 is installed on the swing arm 2. When the driving member 3 drives the swing arm 2 to rotate a certain angle, the positioning rod 5 abuts against the positioning part 4, and the swing arm 2 stops rotating. At this time, the clamping arm 26 on the clamping mechanism is just aligned with the feeding channel. The positioning rod 5 and the positioning part 4 of the rotating mechanism form a positioning structure, so that the clamping mechanism can swing to the same position every time, so that the clamping arm 26 can be accurately aligned with the feeding channel, avoiding deviation when clamping the buttons, and ensuring accurate clamping of the buttons.

[0037] like Figure 1 As shown, in this embodiment, a second positioning rod 6 is connected to the positioning portion 4 , and the second positioning rod 6 can abut against the inner end portion of the swing arm 2 .

[0038] The button clamping mechanism 25 is installed on the outer end of the swing arm 2. When the driving member 3 drives the swing arm 2 to rotate in the opposite direction for a certain angle, the positioning rod 2 6 abuts against the inner end of the swing arm 2, and the swing arm 2 stops rotating. At this time, the clamping arm 26 on the clamping mechanism is just aligned with the button sewing mechanism of the button sewing machine. The button clamped by the clamping arm 26 is accurately sent to the place on the clothes where the button is to be sewn. The positioning rod 2 6 and the positioning part 4 of the rotating mechanism form another positioning structure, so that the clamping mechanism can be accurately aligned with the button sewing mechanism.

[0039] like Figure 1 、 3 As shown in Figure 4, in this embodiment, the positioning portion 4 is a limit block 7, a limit slot 8 is provided on the mounting seat 1, the limit slot 8 is tilted, the limit block 7 is located in the limit slot 8 and can slide in the limit slot 8, a strip groove 9 is provided on the limit block 7, a bolt 10 is passed through the strip groove 9, the bolt 10 and the strip groove 9 can slide relative to each other, and the bolt 10 threadedly fastens the limit block 7 in the limit slot 8. In this structure, by loosening the bolt 10, the limit block 7 can slide in the limit slot 8, so that the position of the limit block 7 and the positioning rod 1 5 or the positioning rod 2 6 can be adjusted according to their position, so that the limit block 7 and the positioning rod 1 5 or the positioning rod 2 6 can fully contact each other, and the positioning is more accurate. After the position is adjusted, the limit block 7 can be conveniently fixed by tightening the bolt 10.

[0040] As another embodiment, the positioning portion 4 may also be a positioning plate or a boss, etc., and its shape is not limited.

[0041] like Figure 1As shown in FIG. 2 , in this embodiment, the inner end of the swing arm 2 has a curved surface 11, against which the second positioning rod 6 can abut. After the swing arm 2 swings to a certain angle, the curved surface 11 and the second positioning rod 6 abut at all times as the swing arm 2 moves toward the button fastening mechanism, reducing shaking during the swinging of the swing arm 2 and improving its stability.

[0042] like Figure 1 and 5 As shown, in this embodiment, the inner end of the swing arm 2 has a contact surface 12, which is a plane, and the positioning rod 2 6 can contact the contact surface 12. The plane contact surface 12 can contact the positioning rod 2 6 more fully, playing a better positioning role.

[0043] like Figure 1 and 3 As shown, in this embodiment, the top of the positioning portion 4 has a second abutment surface 13, which is a plane, and the positioning rod 1 5 can abut against the second abutment surface 13. The plane-shaped abutment surface 13 can abut against the positioning rod 1 5 more fully, thereby achieving a better positioning effect.

[0046] The buffer pad 17 and the push rod 16 form a limit buffer structure, which can limit the fixed plate 14 and prevent the fixed plate 14 from moving beyond the limit. The buffer pad 17 is made of elastic material. When the push rod 16 collides with it, it plays a buffering role to prevent the push rod 16 from being damaged due to collision.

Driving element 2 15 is a cylinder 21 or a linear motor, the piston rod 24 of cylinder 21 or the output shaft of the linear motor being connected to fixed plate 14. A guide rail 22 is fixed to swing arm 2, and a slider 23 is fixed to fixed plate 14, which is slidably connected to guide rail 22.
