Description

Technical Field

[0001] The present invention belongs to the technical field of button riveting machines, and particularly refers to a button riveting machine. Background Art

[0002] A button riveting machine is a device for riveting buttons onto clothes, fabrics, etc.

[0003] After being decelerated by an internal speed reducer, the button riveting machine automatically rivets buttons. The existing speed reducer is relatively large in volume, occupying more space, and the operating space for workers is small; in addition, the longitudinal punching and transverse feeding speeds of the existing button riveting machine are not reasonably designed.

[0004] For example, there is a Chinese patent with the application number CN202021119046.2. The utility model discloses an automatic counter-punching button machine, which includes a workbench, an upper die, a lower die, a fixed frame, a first push rod, a second push rod, and a lever plate. The fixed frame is installed on the workbench. A cam is rotatably installed on the front side of the fixed frame, and a first eccentric wheel is rotatably installed on the rear side of the cam. A switching swing rod is provided on the first eccentric wheel. By the rotation of the cam, the connected switching swing rod is driven. The switching swing rod pushes the first push rod, and the first push rod pushes the upper die to punch the button downward. At the same time, through the push of the cam, the second push rod causes the lever plate to perform a lever principle movement, pushing the lower die upward to move, realizing the mutual counter-punching of the upper die and the lower die, and punching the button completely onto the material.

[0005] However, since the power for both longitudinal punching and transverse feeding is provided by a connecting rod driven by a speed reducer, the longitudinal punching and transverse feeding are basically the same. During long-term operation, due to reasons such as the lubrication of parts, the speeds of longitudinal punching and transverse feeding will differ, and further, problems such as longitudinal empty punching or interference between longitudinal riveting and transverse feeding of the riveting machine will occur. Summary of the Invention

[0006] The purpose of the present invention is to provide a button riveting machine that controls the longitudinal punching and the transverse feeding of the feeding device respectively through a riveting connecting rod mechanism and a swing arm mechanism, so that the longitudinal punching and the transverse feeding are controllably staggered, solving the problems of longitudinal empty punching or interference between longitudinal riveting and transverse feeding of the riveting machine.

[0054] One end of the linkage mechanism is connected to the swinging member.

[0055] The outstanding and beneficial technical effects of the present invention compared with the prior art are:

[0056] 1. The riveting machine controls longitudinal punching and riveting through the riveting link mechanism, and drives the feeding device to feed laterally through the swing arm mechanism, so that the longitudinal punching and riveting and the lateral feeding are controllably staggered, thereby avoiding the problems of longitudinal empty punching or interference between longitudinal riveting and lateral feeding of the riveting machine.

[0057] 2. When the feeding device of the riveting machine provided in this embodiment is reset, it is driven by the first swing arm, and the first swing arm is powered by the linkage mechanism; when the feeding device feeds, the linkage mechanism cannot provide driving force. At this time, the return spring is in a stretched state and has a tendency to return, thereby driving the first swing arm to feed.

[0058] 3. The first swing arm is connected to the sliding part through the limit post, so that the first swing arm can drive the sliding part to move left and right along the guide rail, thereby feeding or resetting.

[0059] 4. The design of the bending part shortens the feeding stroke of the sliding part, so that the volume of the device can be reduced; and because the feeding stroke is shortened, the demand for driving force is also reduced.

[0060] 5. By arranging the rolling parts, the force application point of the second feeding rod on the first swing arm moves reciprocally on the first swing arm. Furthermore, when the feeding device is reset, during the process of the rolling parts rolling from top to bottom, the swing amplitude of the first swing arm is first large and then small; conversely, when the feeding device feeds, during the process of the rolling parts rolling from bottom to top, the swing amplitude of the first swing arm is first small and then large. Therefore, the feeding device feeds slowly first and then fast, and resets fast first and then slow, avoiding interference with longitudinal punching and riveting.

[0061] 6. The buffer groove is designed to be arc-shaped, and the tangent direction of the buffer groove tends to be vertical, so that the buffer groove is adapted to the swinging trend of the first swing arm, increasing the stability of product feeding.

[0062] 7. The inclined setting of the abutting part can make the rolling element closer to the top at the starting position of the first swing arm compared with the parallel setting. And the closer to the top, the greater the swing stroke of the first swing arm. Therefore, such a design can ensure that the feeding device can send the buttons to the riveting position.

[0063] 8. The driving device formed by the motor, reduction gear set and eccentric mechanism is more flexible to use compared with the existing integral speed reducer. The riveting speed of the riveting machine can be adjusted by adjusting the reduction gear set. At the same time, the driving device is arranged in the housing, making the appearance cleaner and tidier, and also avoiding the detachment and collision of the driving device.

[0064] 9. By setting the linkage mechanism, a power source of the driving device drives the punching and riveting mechanism and the swing arm mechanism connected to the linkage mechanism, so that the longitudinal punching and riveting controlled by the punching and riveting mechanism and the lateral feeding controlled by the swing arm mechanism have different speeds.

[0078] The present invention will be further described below with specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0079]

Embodiment 1

[0080] Embodiment 1 specifically provides a button riveting machine.

[0081] Specifically look Figure 1 , Figure 1 is the structural schematic diagram of Embodiment 1. As Figure 1 shown, this embodiment specifically provides a button riveting machine, including a frame 5, a feeding device 3, a feeding device 2, a driving device 1 and a transmission device 6.

[0082] Among them, a lower die member and an upper die member for receiving buttons are provided on the frame 5; the feeding device 3 is installed on the frame 5 for transporting buttons; the feeding device 2 is used to transport the buttons transported out by the feeding device 3 to the upper die member and the lower die member; the driving device 1 is installed on the frame 5; the transmission device 6 is located inside the frame 5 and is connected to the driving device 1 and the feeding device 2. It should be noted that the upper die member and the lower die member are used to fix the upper buckle and the lower buckle and then rivet them together, and the upper die member and the lower die member are already prior art, and there are also upper die members and lower die members in the comparative document, and Figure 1 are blocked by the frame 5 and thus are not shown and described.

[0083] As Figure 1 shown, the frame 5 basically covers the entire button riveting machine. A protective cover 52 is provided at the upper end of the frame 5, and a motor 11 is provided inside the protective cover 52. The protective cover 52 is used to protect the motor 11.

[0084] As Figure 1 shown, an operation space is provided in the middle of the button riveting machine. The operation space is the position where button riveting and the user perform operations. Among them, a feeding device 2 is on the right side of the operation space, and feeding devices 3 are on both sides of the feeding device 2. The feeding device 3 includes an upper button feeding part 313 and a lower button feeding part 323. The upper button feeding part 313 and the lower button feeding part 323 respectively transport upper buttons and lower buttons to the operation space. Among them, the upper buttons are transported to the upper die member, and the lower buttons are transported to the lower die member.

[0085] As Figure 1 shown, the upper button feeding part 313 includes an upper vibrating plate 311 and an upper button feeding track 312; the lower button feeding part 323 includes a lower vibrating plate 231 and a lower button feeding track 322. The upper button feeding part 313 and the lower button feeding part 323 are respectively arranged on both sides of the frame 5, so that the upper button feeding part 313 and the lower button feeding part 323 can feed materials simultaneously. The upper buttons enter the upper die member from the upper vibrating plate 311 through the upper button feeding track 312, and the lower buttons enter the lower die member from the lower vibrating plate 321 through the lower button feeding track 322.

[0086] As Figure 1 shown, an operating platform 51 is provided outside the lower end of the frame 5. The user can control the motor 11 through the operating platform 51 and thus control the button riveting machine.

[0087] As Figure 1 shown, the bottom end of the frame 5 is connected to the support mechanism 4. The support mechanism 4 at least has: a support plate 41, a braking part 42, and a moving part 43. The support plate 41 is connected to the bottom end of the frame 5. The braking part 42 is installed on the support plate 41 and is used for the user to control the feeding device 2 to stop feeding; a moving part 43 is installed under the support plate 41, and the moving part 43 is used to move the button riveting machine.

[0088] As Figure 1 shown, the moving part 43 at least has 4 roller members 431. The roller members 431 can roll to move the button riveting machine, which is convenient for the user to adjust the position or direction, etc.

[0089] As Figure 1As shown, the braking part 42 at least has a foot pedal 421, which is located on the support plate 41 for the user to step on. When the user hopes to stop the feeding, for example, when a button gets stuck, the feeding can be stopped by stepping on the foot pedal 421. The existing braking method is achieved through a braking wrench and requires manual operation. However, during work, the user's hands often need to operate in the operation space, so it is rather inconvenient. Changing to using the foot pedal 421 not only saves effort but also is convenient, liberating both hands.

[0090] Among them, from Figure 2 It can be seen that the specific braking method of the foot pedal 421 is to control the braking member 422 through the foot pedal 421, and there is a wire connected between 422 and the feeding device 2, so the feeding device 2 can be made to stop working.

[0091] Figure 2 It is a schematic diagram after hiding the frame in the first embodiment. As Figure 1 、 Figure 2 shown, the transmission device 6 includes a riveting link mechanism 61, with an upper die member provided at its lower end; a linkage mechanism 62, whose front end is connected to the riveting link mechanism 61 and whose rear end abuts against the swing arm mechanism 63; and a swing arm mechanism 63, whose lower end is movably connected to the feeding device 2;

[0092] The riveting machine provided in this embodiment controls the longitudinal punching through the riveting link mechanism 61, drives the feeding device 2 to feed laterally through the swing arm mechanism 63, so that the longitudinal punching and the lateral feeding are controllably staggered in time, thus avoiding the problems of longitudinal empty punching or interference between longitudinal riveting and lateral feeding of the riveting machine.

[0093] Figure 3 It is one of the schematic diagrams of the driving device and the transmission device in the first embodiment. As Figure 3 shown, the driving device 1 at least has a motor 11; and an eccentric mechanism 12, which is installed on the frame 5 and connected to the transmission device 6; a housing 13, which is detachably installed on the frame 5 and forms an installation cavity with the frame 5, where the housing 13 is visible in Figure 1 ; a reduction gear set 14, which is installed on the side walls inside the two ends of the frame 5 and is respectively connected to the motor 11 and the eccentric mechanism 12; the driving device 1 and the transmission device 6 are arranged in the installation cavity.

[0094] Among them, the motor 11 first drives the reduction gear set 14 to rotate, then the gear set 14 drives the eccentric mechanism 12 to move, and further drives the transmission device 6 to move. Specifically, the eccentric mechanism 12 drives the riveting link mechanism 61 to move.

[0095] As Figure 3As shown in the figure, the motor 11 protrudes an organic shaft 113 towards the gear set 14, and a first gear 112 is installed on the shaft 113; the gear set 14 has at least a first gear 112, a second gear 1111, a third gear 1112, and a fourth gear 1113; among them, the first gear 112 is sleeved outside the shaft 113 and rotates synchronously with the shaft 113, the second gear 1111 is located below the first gear 112 and meshes with the first gear 112, so the second gear 1111 rotates synchronously with the first gear 112; the third gear 1112 is coaxially arranged with the second gear 1111, so the third gear 1112 rotates synchronously with the second gear 1111; the fourth gear 1113 meshes with the third gear 1112 and is located below the third gear 1112, so the fourth gear 1113 rotates synchronously with the third gear 1112. Therefore, the motor 11 drives the rotation of the gear set 14.

[0096] It should be noted that in this embodiment, the cooperation of the motor 11 and the gear set 14 is used to drive the riveting link mechanism 61 as the power of the button riveting machine. And in the gear set 14, the number of teeth of the first gear 112 is less than that of the second gear 1111, and the number of teeth of the third gear 1112 is less than that of the fourth gear 1113. Therefore, the overall gear set 14 has a deceleration effect. The existing button riveting machine uses a reducer as the power. Although it is convenient to install, its specifications are relatively fixed, usually installed outside the frame 5, which affects the appearance and is easy to be bumped. The driving device 1 formed by the motor 11, the reduction gear set 14, and the eccentric mechanism 12 is more flexible to use. At the same time, the gears of the gear set 14 can be adjusted arbitrarily to meet the needs of the connecting rod part 11, which is very flexible. The riveting speed of the riveting machine can be adjusted by adjusting the reduction gear set 14. At the same time, the driving device 1 is arranged in the shell, making the appearance more refreshing and tidy, and also avoiding the falling off and bumping of the driving device 1.

[0097] As Figure 3 shown, the fourth gear 1113 rotates synchronously with the eccentric mechanism 12, and the eccentric mechanism 12 is connected to the riveting link mechanism 61.

[0098] As Figure 3 shown, the riveting link mechanism 61 has at least a first punching rod 611 and a swinging member 612. The first punching rod 611 is connected to the eccentric mechanism 12 and moves synchronously with the eccentric mechanism 12. The swinging member 612 is hinged inside the frame 5 and one end is connected to the first punching rod 611; and a punching mechanism 613, one end of which is hinged to the swinging member 612, and the upper die member is arranged at the other end of the punching mechanism 613; one end of the linkage mechanism 62 is connected to the swinging member 612.

[0099] By setting up the linkage mechanism 62, a driving device 1 drives a riveting mechanism 613 and a swing arm mechanism 63 connected to the linkage mechanism 62 with one power source, so that the longitudinal riveting controlled by the riveting mechanism 613 and the lateral feeding controlled by the swing arm mechanism 63 have different speeds.

[0100] As Figure 3 shown, the feeding device 2 at least has a sliding part 21, an upper buckle guide rail 22 and a lower buckle guide rail 23. The sliding part 21 is used to push the button into the operation space from the upper buckle guide rail 22 and the lower buckle guide rail 23. Channels for the button to pass through are provided inside the upper buckle guide rail 22 and the lower buckle guide rail 23, and they are respectively connected to the upper buckle feeding track and the lower buckle feeding track.

[0101] As Figure 3 shown, the riveting mechanism 613 punches and rivets the button in the operation space under the control of the swing member 612 and then resets, and works reciprocally like this. The process of the riveting mechanism 613 punching and riveting the button is already a relatively mature technology in the field of button riveting machines, so it will not be elaborated here.

[0102] Figure 4 is the second schematic diagram of the driving device and the transmission device in the first embodiment. Combining Figure 3 , as Figure 3-4 shown, further, the swing arm mechanism 63 at least has: a first swing arm 631, the upper end of which is rotatably arranged on the frame 5, the lower end is formed with a buffer groove 6311 and is connected to the feeding device 2; a return spring 632 is arranged on the frame 5 and is connected to the middle part of the first swing arm 631 for pushing the feeding device 2 to extend. The specific situation of the return spring 632 is shown in Figure 5 .

[0103] When the feeding device 2 of the riveting machine provided in this embodiment resets, it is driven by the first swing arm 631, and the first swing arm 631 is powered by the linkage mechanism 62; when the feeding device 2 feeds, the linkage mechanism 62 cannot provide a driving force. At this time, the return spring 632 is in a stretched state and has a tendency to reset, and then drives the first swing arm 631 to feed.

[0104] The rear end of the linkage mechanism 62 is slidably abutted against the front side of the first swing arm 631. The driving device 1 overcomes the elastic force of the return spring 632 through the linkage mechanism 62 to make the first swing arm 631 rotate around the upper fixed point, realizing the pushing back of the first swing arm 631.

[0105] As Figure 3-4 shown, one end of the swing arm mechanism 63 is provided with a buffer groove 6311, which is slidably arranged on the feeding device 2; the feeding device 2 at least has a sliding part 21, which is driven by the first swing arm 631 and is used to push the button to the upper die member and the lower die member and then reset; and a limiting column 211 protrudes from the sliding part 21 and extends into the buffer groove 6311.

[0106] As shown Figure 4 in, in combination with Figure 3 , an upper buckle push rod 221 and a lower buckle push rod 231 are respectively arranged between the upper buckle guide rail 22 and the lower buckle guide rail 23 and the sliding part 21. The upper buckle push rod 221 and the lower buckle push rod 231 are driven by the sliding part 21 and respectively push the upper buckle and the lower buckle into the upper die member and the lower die member.

[0107] The swing arm 631 is connected to the sliding part 21 through the limit post 211, so that the swing arm 631 can drive the sliding part 21 to move left and right along the guide rail, thereby feeding or resetting.

[0108] As shown Figure 4 in, the swing arm 631 has at least a bent part 6312, which is connected to the buffer groove 6311; the bent part 6312 is arranged approximately perpendicular to the sliding part 21. The design of the bent part 6312 shortens the feeding stroke of the sliding part 21, thereby reducing the volume of the device; and since the feeding stroke is shortened, the demand for driving force is also reduced.

[0109] As shown Figure 4 in, the linkage mechanism 62 has at least a first feeding rod 621, which is connected to the riveting link mechanism 61; and a second feeding rod 622, one end of which is hinged to the first feeding rod 621, and the other end is provided with a rolling member 6211, and the rolling member 6211 abuts against the swing arm 631. By arranging the rolling member 6211, the force application point of the second feeding rod 622 on the swing arm 631 reciprocates on the swing arm 631. Furthermore, when the feeding device 2 is reset, during the process of the rolling member 6211 rolling from top to bottom, the swing amplitude of the swing arm 631 is first large and then small; conversely, when the feeding device 2 feeds, during the process of the rolling member 6211 rolling from bottom to top, the swing amplitude of the swing arm 631 is first small and then large. Therefore, the feeding device 2 feeds slowly first and then fast, and resets fast first and then slow, thus avoiding interference with the longitudinal punching and riveting.

[0110] As shown Figure 4 in, the buffer groove 6311 is arc-shaped, so that the tangent of the buffer groove 6311 tends to be perpendicular from top to bottom. It should be noted that Figure 4 due to the perspective problem, the buffer groove 6311 does not match the description. The specific shape of the buffer groove 6311 can be seen in Figure 5-8 . The buffer groove 6311 is mainly used for the sliding of the limit post 211. During the process of the rolling member 6211 rolling from top to bottom, the swing amplitude of the swing arm 1123 is first large and then small. Therefore, the tangent direction of the buffer groove 6311 is designed to gradually tend to be perpendicular, which is adapted to the change of the swing amplitude of the swing arm 1123.

[0111] As shown Figure 4As shown, the second feeding rod 622 has at least a connecting portion 6221, one end of which is hinged to the first feeding rod 621; and a abutting portion 6222, one end of which abuts against the first swing arm 631. Wherein, through holes are provided at the other ends of the connecting portion 6221 and the abutting portion 6222 and are coaxially arranged. Through Figure 4 It can be seen that there is a certain distance between the first swing arm 631 and the first feeding rod 621. Through the design of the connecting portion 6221 and the abutting portion 6222, the second feeding rod compensates for the distance between the first swing arm 631 and the first feeding rod 621 without losing power.

[0112] Wherein, the abutting portion 6222 is inclined towards the connecting portion 6221, so that the rolling member 6211 abuts against the upper end portion of the first swing arm 631. The inclined setting of the abutting portion 6222 can make the rolling member 6211 closer to the top at the starting position of the first swing arm 631 compared with the parallel setting. And the larger the swing stroke of the first swing arm 631 is closer to the top. Therefore, such a design can ensure that the feeding device 2 can feed the buttons into the riveting position.

[0113] As Figure 4 shown, the second feeding rod 622 is fixed on the frame 5. Therefore, the second feeding rod 622 swings around the fixed point with the first feeding rod 621. At the same time, a rolling member 6211 is provided at the other end of the second feeding rod 622. The rolling member 6211 abuts against the third feeding rod 1123 and moves on the third feeding rod 1123. During the process of the rolling member 6211 abutting against and sliding on the third feeding rod 1123, the third feeding rod 1123 is pushed to swing. At the same time, the lower end of the third feeding rod 1123 is clamped with the feeding device 2, thereby driving the feeding device 2 to feed or reset.

[0114] As Figure 4 shown, when the second feeding rod 622 is driven by the first feeding rod 621 to make the rolling member 6211 roll on the third feeding rod 1123, the third feeding rod 1123 is simultaneously driven by the second feeding rod 622 to move to the right. And during the movement of the rolling member 6211 from top to bottom, the position of the rolling member 6211 is the force fulcrum of the third feeding rod 1123. Due to the change of the force fulcrum, the moving amplitude of the third feeding rod 1123 is first large and then small. And during the rightward movement of the third feeding rod 1123, the sliding portion 21 is driven to move to the right. At this time, the feeding device 2 is in the reset stage. Therefore, the moving amplitude of the third feeding rod 1123 being first large and then small can enable the feeding device 2 to quickly reset and avoid interference with the punching and riveting mechanism 613;

[0115] Conversely, during the upward movement of the rolling member 6211, the movement amplitude of the third feeding rod 1123 is small first and then large. At this time, it is the feeding stage. Therefore, the feeding method of small first and then large makes the feeding of the sliding portion 21 slow first and then fast, giving the user sufficient operation time. At the same time, when the riveting mechanism 613 is in place, the sliding portion 21 moves quickly, enabling the feeding to be completed quickly.

[0116] It should be noted that Figure 4 The state shown in [Figure] is the state where the button feeding is in place. At this time, the sliding portion 21 needs to move to the right to end the button feeding.

[0117] Specifically, look at Figure 5 , Figure 5 is a schematic diagram of the state where the button feeding ends. As Figure 5 shown, at this time the button feeding ends. Therefore, the feeding device 2 needs to be reset. The rolling member 6211 slides downward against the third feeding rod 1123, driving the third feeding rod 1123 to move to the right, causing the sliding portion 21 to slide to the right; and at this time, the position of the rolling member 6211 is at the upper end of the third feeding rod 1123. Therefore, the swinging amplitude of the third feeding rod 1123 is relatively large, that is, the reset process of the feeding device 2 is relatively fast in the entire feeding and reset cycle, avoiding interference between the feeding device 2 and the riveting mechanism 613 during feeding. After reset, the riveting mechanism 613 starts riveting.

[0118] As Figure 5 shown, a reset spring 632 is also provided inside the frame 5 and is fixed by a fastener passing through the frame. Both ends of the reset spring 632 are connected to the fastener and the third feeding rod 1123 respectively. When the third feeding rod 1123 and the sliding portion 21 slide to the right, they are driven by the force of the second feeding rod 622; while when the third feeding rod 1123 and the sliding portion 21 slide to the left, they are assisted by the reset spring 632.

[0119] Figure 6 is a schematic diagram of the state of the connecting rod portion 11 when the riveting mechanism 613 is riveting. As Figure 6 shown, at this time the riveting mechanism 613 rivets the button, the rolling member 6211 continues to slide downward, driving the third feeding rod 1123 to move to the right, causing the sliding portion 21 to slide to the right; after riveting is completed, at this time the sliding portion 21 moves to the rightmost end and is ready to slide to the left to start feeding, and at the same time the riveting mechanism 613 resets.

[0120] Specifically, look at Figure 7 , Figure 7 is a schematic diagram of the state when the button starts feeding. As Figure 7 shown, at this time the button starts feeding, and the sliding portion 21 needs to move to the left. Therefore, the rolling member 6211 slides upward, driving the third feeding rod 1123 to move to the left, causing the sliding portion 21 to slide to the left; until the riveting mechanism 613 is in place.

[0121] See specifically Figure 8 , Figure 8 It is a schematic diagram of the state when the riveting mechanism 613 is in place and waiting for button feeding. As Figure 8 shown, at this time, the riveting mechanism 613 is in place and waiting for button feeding. After the riveting mechanism 613 is in place, the rolling member 6211 continues to slide upward, driving the third feeding rod 1123 to move leftward, causing the sliding portion 21 to slide leftward; and at this time, the position of the rolling member 6211 is closer to the upper end compared to when feeding starts, so the swing amplitude of the third feeding rod 1123 is larger, that is, after the riveting mechanism 613 is in place, the feeding speed of the feeding device 2 is very fast and there will be no interference with the riveting mechanism 613. After the feeding device 2 sends the button to the operation space, it enters the state where the button feeding is in place, that is, it returns to Figure 4 the state shown, and the cycle is completed.

[0122] Working principle: When the button riveting machine provided in this embodiment is working, the connecting rod portion 11 causes the riveting mechanism 613 to move downward, and at the same time, the button starts to be fed; when the riveting mechanism 613 is in place and waiting for button feeding, the feeding speed increases; after the button feeding is in place, the button feeding ends, the feeding device 2 starts to reset, and then the riveting mechanism 613 starts to rivet; after the riveting is completed, the riveting reset completes a cycle and repeats cyclically.

[0123] The above embodiments are only preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
