Description

Technical Field

[0001] This technical solution relates to the field of button attaching machine technology, specifically to a button feeding mechanism and a button attaching machine. Background Technology

[0002] Riveting machines, also known as button attaching machines, are widely used in garment factories and leather goods processing enterprises. They are mainly used to attach various types of metal buttons to knitted garments, down jackets, denim clothing, shoes, hats, leather products, etc. Some button attaching machines have independent punching rods and button attaching rods, which can perform punching and then attaching buttons. Some button attaching machines only have button attaching rods, which have punching and button attaching functions, or independent button attaching functions. For button attaching machines with only button attaching rods, the button attaching rod usually moves downward and closer to the button feeding mechanism after the button feeding mechanism has moved into place. In actual work, this action not only takes time, but also causes the entire workflow to be discontinuous.

[0003] Chinese patent CN214127200U discloses a riveting machine. The working principle of this riveting machine is as follows: the feeding vibratory plate conveys the fastener to the upper fastener feeding device, and then the upper fastener is pushed to the upper fastener receiving device by the upper fastener push rod. Finally, the riveting upper die is driven to descend and grab the fastener by the punch rod to perform the fastening operation. This working method requires the punch rod to descend to pick up the material and then return to its position, instead of the upper fastener feeding device directly conveying the material to the upper die. The fastening time is longer, which affects the overall processing efficiency. At the same time, the power source of the punch rod device is frequently started, which will shorten its service life. Summary of the Invention

[0004] The purpose of this technical solution is to provide a button feeding mechanism and a button attaching machine. By controlling the movement and lifting of the lifting seat through a movable lifting component, the button can be delivered to a designated position, so that the button attaching rod does not need to be lowered to retrieve the button, thus solving the problem of the cumbersome and time-consuming working process of the original button feeding mechanism.

[0005] The purpose of this technical solution is achieved as follows:

[0006] A fastener feeding mechanism includes: a slide assembly for mounting on a fastener attaching machine frame; a fastening assembly movably mounted on the slide assembly and having a fastening position; a swing member, the middle of which is hinged to the slide assembly and the front end of which is movably connected to the fastening assembly; and a drive assembly mounted on the fastener attaching machine frame at the rear of the slide assembly, with its output end connected to the rear end of the swing member; wherein the rear end of the swing member is provided with an action part, the output end of the drive assembly abuts against the action part, and the action part has a first position and a second position; when the output end of the drive assembly abuts against the first position, the fastening assembly is in a fastening state, used to receive fasteners fed from the feed channel; when the output end of the drive assembly abuts against the second position, the fastening assembly is in a fastening feeding state, used to lift the fastener in the fastening position and send it below the punch.

[0007] Preferably, the actuating part of the swing member is configured as a movable groove, which is inclined upward along the forward direction of the drive assembly. The lower end of the movable groove is the first position of the actuating part, and the upper end is the second position of the actuating part. The output end of the drive assembly is provided with a pushing part, which is movably disposed in the movable groove.

[0008] Preferably, the actuating part of the swing member has an inclined surface, which is inclined upward along the forward direction of the driving assembly, with the lower end of the inclined surface being a first position and the upper end being a second position; the output end of the driving assembly is provided with a second pushing part, which movably abuts against the inclined surface; and a reset torsion spring is provided outside the swing member.

[0009] Preferably, the fastening assembly includes: a fastening seat, which is movably disposed on a slide of the slide assembly; a support rod, which is inserted into the fastening seat; a receiving seat, which is movably disposed on the support rod, and the receiving seat has a fastening position; and a buffer spring, which is sleeved on the support rod for supporting the receiving seat; wherein, the fastening seat is connected to the front end of the swing member through a connecting structure; when the swing member pulls the fastening seat up, the fastening seat abuts against the lower end of the punch rod, so that the fastener in the fastening position is engaged with the lower end of the punch rod.

[0010] Preferably, the connecting structure includes a through hole at the upper end of the buckle seat, a connecting rod disposed on the through hole, and an oblong hole at the front end of the swing member, wherein the connecting rod passes through the oblong hole.

[0011] Preferably, the connection structure includes: a connecting part disposed at the rear end of the swing member, the connecting part having a groove; and a sliding button disposed on the side wall of the fastener seat, the sliding button being movably positioned within the groove.

[0012] Preferably, the slide assembly includes: a slide one on which the swing member is disposed; and a slide rail mounted on the fastener frame, wherein the slide one is movably disposed on the slide rail via a slider one.

[0013] Preferably, the slide assembly further includes: a second slide, which is movably mounted on the slide rail via a second slider, and the pushing part of the driving component is mounted on the second slide, the pushing part being movably connected to the actuating part.

[0014] Preferably, the fastening mechanism further includes a reset assembly, comprising: a reset guide rod, one end of which is fixed to the first slide and the other end of which movably passes through the second slide; and

[0015] A reset spring is sleeved outside the reset guide rod, and its two ends abut against slide two and slide one, respectively.

[0016] A button attaching machine includes: a button attaching machine frame having a stop block; a button feeding mechanism disposed within the frame; and a button attaching mechanism including a punch rod for cooperating with the button feeding mechanism to complete the button attaching work; wherein the front end of the slide rail abuts against the stop block, and the stop block is used to limit the slide block.

[0017] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0018] 1. The mobile lifting component designed in this technical solution can transport the snap fastener forward and lift it upward, transporting the snap fastener to below the snap fastener rod so that it can be attracted by the snap fastener rod. This eliminates the process of the snap fastener rod moving downward to attract the snap fastener, and also eliminates the gap between switching work steps. This saves the workflow and greatly improves the snap fastener processing efficiency.

[0019] 2. The swinging component designed in this technical solution can swing freely. After one end is subjected to pressure and swings, the other end can be raised. The design of the movable groove can realize the movement of the swinging component simultaneously, so that the fastener is conveyed through only one part. The overall structure is simple and the power transmission efficiency is high. Attached Figure Description

[0027] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0028]

Example 1

[0029] like Figure 1 and Figure 2 As shown, a button attaching machine includes a button attaching frame 1, a button feeding mechanism, a button attaching mechanism, and a lower die (not shown in the figure). This application improves the button attaching machine with a single punch 12. When the button attaching machine is working, the button feeding mechanism is set inside the button attaching frame 1 and can reciprocate. The button feeding mechanism delivers the fastener to the bottom of the button attaching mechanism for the punch 12 to absorb. The punch 12 then works with the lower die to complete the button attaching task. Therefore, in this process, the button attaching mechanism does not need to actively move downward to the button feeding mechanism, which simplifies the workflow and improves processing efficiency.

[0030] like Figure 2-4 As shown, the fastening mechanism includes a slide assembly 2, a fastening assembly 3, a swinging member 4, and a drive assembly 5. The drive assembly 5 is used to provide power for the movement of the slide assembly 2 and the fastening assembly 3, and also to provide power for the lifting and lowering of the fastening assembly 3. The swinging member 4 is used to transmit the power input from the drive assembly 5, which drives the slide assembly 2 to move and the fastening assembly 3 to lift and lower.

[0031] Specifically, the slide assembly 2 includes a slide rail 23 and a slide block 21. The slide rail 23 is horizontally arranged inside the fastener frame 1. The slide block 21 is movably arranged on the slide rail 23 via a slider 22. The middle part of the swing member 4 is rotatably arranged on the slide block 21. The fastening assembly 3 is movably connected to the front end of the swing member 4. In this way, when the swing member 4 is subjected to a horizontal thrust, it can drive the slide block 21 to move horizontally. When the rear end of the swing member 4 is subjected to a non-horizontal thrust, it can swing, causing the front end to rise or fall, thereby realizing the movement and lifting of the fastening assembly 3.

[0032] like Figure 2-4As shown, the fastening assembly 3 includes a fastening seat 32, a support rod 33, a receiving seat 34, and a buffer spring 35. The fastening seat 32 is movably mounted on the slide block 21. A slider is provided between the fastening seat 32 and the slide block 21. The slider can play a connecting and guiding role to increase the stability of the fastening seat 32 during lifting and lowering. The support rod 33 is inserted into the front end of the fastening seat 32. The receiving seat 34 is movably mounted on the support rod 33. The receiving seat 34 has a fastening position 31, which can move up and down on the support rod 33 after being subjected to force. The buffer spring 35 is sleeved on the support rod 33 to support the receiving seat 34. The lower end abuts against the fastening seat 32, and the upper end abuts against the lower end face of the receiving seat 34 to ensure that the receiving seat 34 always has an upward movement tendency. When the swinging member 4 pulls the fastening seat 32 up, the fastening seat 32 abuts against the lower end of the punch rod 12, so that the fastener in the fastening position 31 is engaged with the lower end of the punch rod 12.

[0033] Furthermore, the buckle seat 32 is connected to the front end of the swing member 4 through the connecting structure 36. The front end of the swing member 4 makes a circular motion, and the buckle seat 32 needs to be raised and lowered vertically. Therefore, the connecting structure 36 includes a connecting rod 363, a through hole 361 opened at the upper end of the buckle seat 32, and an oblong hole 362 opened at the front end of the swing member 4. The connecting rod 363 is inserted into the through hole 361 and the oblong hole 362. The design of the connecting structure 36 can ensure the vertical raising and lowering of the buckle seat 32 and accurately dock with the punch rod 12.

[0034] like Figure 2-4 As shown, in order to enable the swing component 4 to drive the buckle seat 32 to move horizontally and vertically, an action part 41 is provided at the rear end of the swing component 4. The action part 41 has a first position 42 and a second position 43. When the output end of the drive component 5 abuts against the first position 42, the buckle component 3 is in the buckling state and is used to receive the fastener sent from the material channel. When the output end of the drive component 5 abuts against the second position 43, the buckle component 3 is in the buckling state and is used to lift the fastener in the buckling position 31 and send it below the punch rod 12. When the output end of the drive component 5 moves from the first position 42 to the second position 43, the buckle component 3 completes the horizontal movement and vertical lifting.

[0035] Specifically, the actuating part 41 of the oscillating member 4 is configured as a movable groove 44, which is inclined upward along the forward direction of the drive assembly 5. The lower end of the movable groove 44 is the first position 42 of the actuating part 41, and the upper end is the second position 43 of the actuating part 41. The output end of the drive assembly 5 is provided with a pushing part 261, which is movably disposed in the movable groove 44. When the pushing part 261 is in the first position 42, it is pushed by the drive assembly 5 and passes through the inclined surface of the movable groove 44. A horizontal thrust is transmitted to the swing member 4. At this time, the fastening assembly 3 moves forward horizontally. When the slide block 21 moves to abut against the stop block 11 set on the fastening frame 1, it can no longer move forward. At this time, the pusher 261 moves along the inclined surface of the movable groove 44 and presses down the rear end of the swing member 4. At this time, the front end of the swing member 4 rotates, realizing the rise of the fastening assembly 3. When the drive assembly 5 returns, due to the gravity of the fastening assembly 3 itself, it falls first and is then pulled by the pusher 261 to move.

[0036] Furthermore, the slide assembly 2 also includes a second slide 24, which is disposed on the output end of the drive assembly 5. The second slide 24 is movably disposed on the slide rail 23 via a second slider 25. The pushing part of the drive assembly 5 is disposed on the second slide 24. The pushing part here includes the first pushing part 261 in embodiment 1 and the second pushing part 262 in embodiment 2. The fastening mechanism also includes a reset assembly 6. The reset assembly 6 includes a reset guide rod 61 and a reset spring 62. One end of the reset guide rod 61 is fixed on the first slide 21, and the other end is movably disposed on the second slide 24. The reset spring 62 is sleeved on the outside of the reset guide rod 61, and both ends abut against the second slide 24 and the first slide 21 respectively, so that the second slide 24 always has a tendency to move away from the first slide 21. The reset assembly 6 is used to ensure that when the drive assembly 5 returns, the fastening assembly 3 descends first and then moves.

[0037] Specifically, the movable groove 44 has a flat groove located near the second position 43. When the pushing part 261 is in the flat groove and is ready to return, the force acting on the groove wall of the movable groove 44 has a vertically upward component. The direction of this component is determined by the angle between the flat groove and the horizontal. This vertical component is used to ensure that the swinging part 4 rotates and moves in a limited manner during the return.

[0038] Furthermore, the first pusher 261 is mounted on the second slide 24, which is located beside the swing member 4. In this way, the first pusher 261 can be movably mounted in the movable slot 44, and the output end of the drive assembly 5 is connected to the second slide 24. Thus, when the output end of the drive assembly 5 outputs power, it can move on the slide rail 23 through the second slide 24 to achieve higher stability.

[0039]

Example 2

[0040] The configuration of this embodiment is largely the same as that of Embodiment 1, except for the structure and connection mechanism of the actuating part 41 of the swing member 4, such as... Figure 5 and Figure 6 As shown, in this embodiment, the working part 41 of the swing member 4 is an inclined surface. The difference between the inclined surface and the movable groove 44 is that the return stroke cannot be achieved by the inclined surface and the second push part 262. Therefore, a reset torsion spring is provided outside the swing member 4. One end of the reset torsion spring abuts against the second slide 24 and the other end abuts against the swing member 4, which is used to realize the automatic reset of the swing member 4 when there is no force. The inclined surface in this embodiment can be compared to a groove wall of the movable groove 44. The inclined surface is inclined upward along the forward direction of the drive component 5. The lower end of the inclined surface is the first position 42 and the upper end is the second position 43. The inclined surface can also be an arc-shaped inclined surface, which can better adapt to the second push part 262. The output end of the drive component 5 is provided with the second push part 262. The second push part 262 moves against the inclined surface. At this time, the output end of the drive component 5 does not need to be set on the side of the swing member 4 as in embodiment 1. The support can be set on the same horizontal line as the swing member 4.

[0041] The connection structure 36 in this embodiment includes a connecting part 364 and a sliding button 366. The connecting part 364 is disposed at the rear end of the swing member 4. The connecting part 364 has a sliding groove 365. The sliding button 366 is disposed on the side wall of the fastener seat 32. The sliding button 366 is movably placed in the sliding groove 365. The connection structure 36 in the two embodiments can be interchanged.
