A safer staple supply mechanism

Abstract

The application discloses a safer nail feeding mechanism and relates to the technical field of riveting equipment. The nail feeding mechanism comprises a nail feeding track, a blocking piece and a trigger piece. The nail feeding track is arranged on a nail feeding barrel. The blocking piece is rotationally arranged at the bottom end of the nail feeding track. The trigger piece is arranged on a storage bin. When the storage bin is replenished with nails, the trigger piece is moved by the storage bin. The trigger piece first contacts the blocking piece and drives the blocking piece to rotate to open a conveying channel. The storage bin then contacts the nail feeding track, so that the rivets in the conveying channel can be supplemented into the storage bin. When the storage bin is completed with the nail replenishment and leaves, the trigger piece is separated from the blocking piece. The blocking piece is rotated to block the conveying channel under the action of gravity. The opening and closing actions of the conveying channel are realized by a pure mechanical driving structure formed by the blocking piece and the trigger piece. The power is derived from the movement of the storage bin, and the dependence on electrical elements such as sensors and driving pieces is completely eliminated, so that the economy of the nail feeding system is remarkably improved.

Description

Technical Field

[0001] This application relates to the field of riveting equipment technology, and in particular to a safer riveting feeding mechanism. Background Technology

[0002] In automated automotive production lines, to improve the continuity and efficiency of the riveting process, riveting systems are typically equipped with rivet storage bins that store multiple rivets, as well as riveting actuators that can automatically retrieve rivets and perform riveting operations. When the rivet reserves in the storage bin are depleted, the system will automatically replenish the rivets. The actuator will move the storage bin to the rivet supply system to replenish the rivets, thus maintaining continuous production.

[0003] Currently, the rivet feeding system includes a rivet feeding bin and a rivet feeding mechanism. The rivet feeding bin stores a large number of rivets, and the rivet feeding mechanism is installed at the discharge end of the rivet feeding bin. The rivet feeding mechanism consists of a rivet feeding track, a drive component, a sealing component, and a sensor. The rivet feeding track is connected to the discharge end of the rivet feeding bin, the sealing component is installed at the discharge end of the rivet feeding track, the drive component is installed on the rivet feeding track and is used to drive the sealing component to open or close the discharge end of the rivet feeding track, and the sensor is installed on the rivet feeding track and is used to control the operation of the drive component.

[0004] When the actuator moves the storage bin to the nail supply mechanism, the sensor controls the drive component to operate. The drive component drives the sealing component to open the discharge end of the nail supply track. After the storage bin is connected to the nail supply track, it can replenish the rivets. When the storage bin has finished replenishing the rivets and leaves the nail supply mechanism, the sensor controls the drive component to operate. The drive component drives the sealing component to close the discharge end of the nail supply track, so that the rivets will not leak.

[0005] The accuracy and reliability of the sealing mechanism's operation are highly dependent on the coordinated control of the drive components and sensors. Currently, commonly used drive solutions include servo motors or cylinders, both of which are high-precision, high-response control elements. When used in conjunction with high-precision sensors, this significantly increases the procurement cost of key components of the nail feeding mechanism, thereby affecting the economics of the nail feeding system. Utility Model Content

[0006] To reduce the cost of rivet feeding systems, this application provides a safer rivet feeding mechanism.

[0007] This application provides a safer nail feeding mechanism using the following technical solution:

[0008] A safer rivet feeding mechanism includes a rivet feeding track, a sealing element, and a trigger element. The rivet feeding track is disposed on a rivet feeding hopper, and a conveying channel for conveying rivets is formed within the rivet feeding track. The sealing element is rotatably disposed at the bottom end of the rivet feeding track and blocks the conveying channel. The trigger element is disposed on a storage bin. During the process of the storage bin moving and connecting to the rivet feeding track, the trigger element drives the sealing element to rotate and open the conveying channel.

[0009] By adopting the above technical solution, when the storage bin is being refilled with rivets, the storage bin drives the trigger to move. The trigger first contacts the sealing component and drives it to rotate, opening the conveying channel. The storage bin then contacts the rivet supply track, allowing rivets in the conveying channel to be replenished into the storage bin. After the storage bin completes the refilling and leaves, the trigger separates from the sealing component, and the sealing component rotates under gravity to seal the conveying channel. With this configuration, the opening and closing of the conveying channel is achieved by a purely mechanical drive structure formed by the sealing component and the trigger, powered by the movement of the storage bin. This completely eliminates the reliance on electrical components such as sensors and drive components, significantly improving the economic efficiency of the rivet supply system.

[0010] Preferably, the sealing component includes a sealing plate, a push block, and two connecting members. The two connecting members are detachably disposed on opposite sides of the bottom of the nail supply track. The two ends of the sealing plate are rotatably disposed on the two connecting members. The push block is fixedly disposed on one side of the sealing plate, and the triggering member moves to contact the push block.

[0011] By adopting the above technical solution, when the storage bin is being patched, the trigger moves to contact the push block, and the push block drives the sealing plate to rotate on the connector, thereby opening the conveying channel. When the storage bin has finished patching and left, the trigger separates from the push block, and the sealing plate rotates to close the conveying channel.

[0012] Preferably, the sealing plate is bent at the side away from the direction of rotation to open the conveying channel, forming a folded edge that is closer to the nail supply track. The end of the folded edge abuts against the bottom wall of the nail supply track and blocks the conveying channel.

[0013] By adopting the above technical solution, after the storage bin completes the nailing and leaves, the sealing plate drives the folded edge to rotate and abut against the bottom wall of the nail supply track, thereby quickly sealing the conveying channel.

[0014] Preferably, the push block has a clearance groove on its side wall, and the trigger is located in the clearance groove.

[0015] By adopting the above technical solution, when the storage bin is connected to the nail supply track, the trigger moves into the clearance groove, making the connection between the storage bin and the nail supply track smoother and reducing the leakage of rivets during the connection process.

[0016] Preferably, the nail supply track includes a track body and a track cover, the conveying channel is opened in the track body, and the track cover is detachably mounted on the track body.

[0017] By adopting the above technical solution, the nail supply track consists of a track body and a track cover. The track cover is detachable from the track body, which facilitates the maintenance of the nail supply track.

[0018] Preferably, there are two conveying channels, and the two conveying channels are parallel to each other.

[0019] By adopting the above technical solution, two conveying channels are used to transport rivets, thereby improving the efficiency of rivet repair.

[0020] Preferably, the nail supply track is provided with a mounting plate, the mounting plate is provided with a mounting bracket, and the mounting bracket is connected to the nail supply barrel.

[0021] By adopting the above technical solution, the nail feeding track is installed using mounting plates and mounting brackets, making the nail feeding track more stable on the nail feeding barrel.

[0022] Preferably, the mounting plate has a mounting groove, the nail supply track is located in the mounting groove, and the track body has a slot on the side away from the track cover, with the mounting plate located in the slot.

[0023] By adopting the above technical solution, the installation of the staple feeding track is limited by the installation groove and the slot, thereby further improving the stability of the staple feeding track installation.

[0024] Preferably, the mounting plate is provided with shock-absorbing pads, and the mounting bracket is mounted on the shock-absorbing pads.

[0025] By adopting the above technical solution and using shock-absorbing pads for vibration reduction, the connection between the storage bin and the nail supply track becomes more stable.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Utilizing a sealing component and a triggering component, when the storage bin is being refilled with rivets, the storage bin drives the triggering component to move. The triggering component first contacts the sealing component and drives the sealing component to rotate and open the conveying channel. The storage bin then contacts the rivet supply track, allowing the rivets in the conveying channel to be replenished into the storage bin. After the storage bin has finished refilling and left, the triggering component separates from the sealing component. The sealing component rotates under the action of gravity to block the conveying channel. The opening and closing of the conveying channel is achieved by a purely mechanical drive structure formed by the sealing component and the triggering component. Its power comes from the movement of the storage bin, completely eliminating the dependence on electrical components such as sensors and drive components, and significantly improving the economy of the rivet supply system.

[0028] 2. With the help of the folded edge, after the storage bin has finished nailing and left, the sealing plate drives the folded edge to rotate and abut against the bottom wall of the nail supply track, thereby quickly sealing the conveying channel;

[0029] 3. By using the clearance groove, when the storage bin is connected to the nail supply track, the trigger moves into the clearance groove, making the connection between the storage bin and the nail supply track smoother and reducing the possibility of rivet leakage during the connection process.

[0036] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0037] This application discloses a safer nail feeding mechanism.

[0038] Reference Figure 1 and Figure 2 A safer nail feeding mechanism includes a nail feeding track 2, a sealing component 3, and a trigger component 1. A mounting plate 7 is fixedly installed in the middle of the nail feeding track 2. Four shock-absorbing pads 11 are fixedly installed on the mounting plate 7. A mounting bracket 8 is fixedly installed on every two shock-absorbing pads 11, and the two mounting brackets 8 are fixedly connected to the nail feeding barrel.

[0039] Reference Figure 2 and Figure 3 The nail feeding track 2 includes a track body 21 and a track cover 22. Two parallel conveying channels 4 are formed within the track body 21. Each conveying channel 4 has its upper and lower ends connected to the discharge end of the nail feeding bucket and the inlet end of the storage bin, respectively. The track cover 22 is installed on one side of the nail feeding track 2 and has two bolts that detachably attach it to the track body 21.

[0040] The track body 21 has a slot 10 on its side wall and a mounting slot 9 on its mounting frame 8. The track body 21 is located in the mounting slot 9 and the mounting frame 8 is located in the slot 10. Two bolts are installed in the mounting frame 8 and the track body 21 is fixedly connected to the mounting frame 8 by the two bolts.

[0041] Reference Figure 4 and Figure 5 The sealing component 3 includes a sealing plate 31, a push block 32, and two connecting members 33. The sealing plate 31 is U-shaped and located at the bottom of the track body 21. The push block 32 is fixedly installed at one end of the sealing plate 31 along its length. The two connecting members 33 are detachably installed on both sides of the track body 21 along its width, and the two connecting members 33 pass through both ends of the sealing plate 31. In this application, the connecting members 33 can be bolts, and the sealing component 3 is rotatably installed at the bottom end of the track body 21 by two bolts.

[0042] The sealing plate 31 has a folded edge 5 formed on one side of its width direction, which is bent towards the track body 21. The folded edge 5 is located on the side of the sealing plate 31 away from itself when it rotates to open the conveying channel 4, and the top of the folded edge 5 abuts against the bottom wall of the track body 21 and is used to block the two conveying channels 4.

[0043] The trigger 1 is installed on the top of the storage bin. In this application, the trigger 1 can be a bolt. The top of the side wall of the push block 32 is provided with a clearance groove 6. During the process of connecting the storage bin with the conveying channel 4, the trigger 1 moves to contact the push block 32. After the storage bin is connected to the conveying channel 4, the trigger 1 moves into the clearance groove 6 of the push block 32.

[0044] The implementation principle of a safer rivet supply mechanism in this application embodiment is as follows: During the rivet replenishment operation in the storage bin, its movement first drives the trigger 1 to displace. The trigger 1 then contacts the push block 32, and the push block 32 drives the sealing plate 31 to rotate, thereby opening the conveying channel 4. Immediately afterwards, the storage bin and the rivet supply track 2 are connected, allowing the rivets in the conveying channel 4 to smoothly enter the storage bin under the action of gravity or pushing.

[0045] After the nailing is completed, the storage bin separates from the nail supply mechanism, and the trigger 1 disengages from the push block 32. The sealing plate 31 automatically rotates under gravity and returns to the closed position, achieving reliable sealing of the conveying channel 4. At this time, the push block 32 acts as a counterweight, facilitating the rapid reset of the sealing plate 31.

[0046] The safer nail feeding mechanism achieves automatic opening and closing of the conveying channel 4 through a purely mechanical linkage structure consisting of trigger element 1 and sealing element 3. Its power comes entirely from the displacement movement of the storage bin, without relying on electrical control components such as sensors and electric drive components. This significantly reduces the manufacturing cost and maintenance complexity of the nail feeding system while ensuring system reliability.

[0047] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
