Description

Technical Field

[0001] This invention relates to the field of coil packing technology, specifically to an automatic coil packing and sorting integrated machine. Background Technology

[0002] Nail coiling machines are mostly used for automatic sorting and packaging of nails. Their working principle is to arrange surface-treated nails in a row and connect them with thin metal wire to form a coil. The angle, spacing, and other parameters of the nails can be adjusted according to customer requirements.

[0003] The nail coiling machine is equipped with a nail separating wheel with grooves on the wheel rim that match the nail head and nail shank. The nail separating wheel is used to separate the messy nails in the feeding bin and position them according to the nail head facing forward, equidistant and fixed angle, to ensure that the posture of each nail is consistent when entering the welding station and to avoid mis-nailing and overlapping nails. The grooves in traditional sizing wheels are mostly created by grinding. This means that each sizing wheel can only be used for coil production with a fixed length and angle of coil nails. When the length and angle of the coil nails change, the corresponding sizing wheel needs to be replaced. In particular, after long-term use, the grooves of the sizing wheel will wear down. The sizing wheel also needs to be removed and transported to a special station for repair or scrapped. This limits the service life and compatibility of traditional sizing wheels.

[0018] Please see Figure 1-7This invention provides a technical solution: an automatic sorting and packaging machine for coil nails, including a nail-separating mechanism in the coil nailing machine. The nail-separating mechanism includes two mounting rings 2 symmetrically arranged front and rear. Each of the two mounting rings 2 has an equal number of universal joints 3 arranged in a circular array around its axis. Each universal joint 3 passes through the mounting ring 2 radially and is elastically slidably connected to a slide rod 4. Each slide rod 4 has a retainer 5 at one end of its outer wall of the mounting ring 2. The retainer 5 is used to retain the nail body. Each slide rod 4 has a connecting block 6 fixedly connected to one end of its outer wall of the mounting ring 2. A telescopic rod 7 is fixedly connected between the corresponding connecting blocks 6 on the two mounting rings 2. The telescopic rod 7 is parallel to the axial direction of the mounting ring 2. A drive assembly is provided, wherein a main shaft 8 is connected to the drive assembly and is coaxially arranged with two mounting rings 2, and the main shaft 8 is used to drive the two mounting rings 2 to rotate synchronously. A feed assembly is provided on the inner side of the mounting ring 2. The feed assembly is used to control all slide rods 4 to slide synchronously relative to the universal joint 3. The front mounting ring 2 is provided with a rotating assembly, which is used to control the front mounting ring 2 to rotate relative to the rear mounting ring 2; The rear mounting ring 2 is provided with a push-pull assembly, which is used to control the longitudinal movement of the rear mounting ring 2 to change the distance between the two mounting rings 2.

[0019] Step 1: Adjust the equipment: In the initial state, the feed assembly is in the reset state, all slide rods 4 maintain the same radial extension length under the constraint of universal joint 3, and the corresponding ferrules 5 on the front and rear mounting rings 2 are collinear, forming a pair of snap-fit ​​units, waiting to receive a single nail a from the coil nailing machine; The equipment is adjusted so that the push-pull assembly (such as an electric push rod or cylinder) moves first, controlling the rear mounting ring 2 to move axially along the main shaft 8, adjusting the distance between the front and rear mounting rings 2 to match the length of the nails to be sorted (ensuring that both ends of the nail can be simultaneously inserted into the corresponding front and rear retaining sleeves 5); then the rotating assembly is started, driving the front mounting ring 2 to rotate relative to the rear mounting ring 2 around the axis of the main shaft 8; at this time, the front and rear retaining sleeves 5 generate a relative rotation angle around the universal joint 3, and under the constraint of the telescopic rod 7, the axes of the front and rear retaining sleeves 5 remain collinear, thereby adjusting the circumferential posture of the subsequent nails after they are engaged, i.e., the angle of the coiled nails; Next, the feed assembly operates, controlling all slide rods 4 to slide synchronously relative to the universal joint 3 along the mounting ring 2 through mechanical contact or transmission. During this process, when the slide rod extends, the ferrule 5 drives the nail to move outward; when the slide rod retracts, the nail moves inward, realizing the uniform adjustment of the radial position of the nail, thereby adjusting the circumferential distance of the nail and completing the adjustment of the nail spacing of the coil nail.

[0020] The single nail output by the coil stapler has its two ends embedded in corresponding retaining sleeves 5. The retaining sleeves 5 fix the nail body through an inner arc groove or elastic buckle structure (not detailed, a conventional snap-fit ​​design), completing the initial positioning of the nail; the process of the coil stapler outputting the nail to the retaining sleeves 5: Example 1: The ferrule 5 is connected to an external sensor. When the ferrule 5 moves to the position where the nail is received, the nail coiling machine outputs the nail into the ferrule 5. Example 2: The outer contact element of the ferrule 5 is connected to the output unit b of the coil nail machine. When the triggering element moves with the ferrule 5 to the nail receiving position, it will trigger the triggering element on the output unit, causing the coil nail machine to output nails to the ferrule 5. Step 2: Synchronous conveying, the rotating installation ring drives the material to move: Once the equipment is adjusted, the drive assembly starts, driving the two mounting rings 2 and their components to rotate synchronously around the axis via the main shaft 8. This causes each pair of snap-fit ​​units to pass through the output unit of the coil nailing machine in sequence, transporting the snap-fit ​​nails from the receiving position to the welding position c. The nails are then welded to the metal wire and transported along the metal wire d to the packaging position for coiling and segmenting operations.

[0021] In this invention, the rear mounting ring 2 moves longitudinally while the front mounting ring 2 rotates, which can fix the shape of the front end of the equipment and prevent the front mounting ring 2 from protruding forward due to the increase in the length of the nail, thus avoiding interference with the work outside the equipment caused by the protruding length of the front mounting ring 2. This invention, through the cooperation of various components, enables the snap-fit ​​unit composed of the front and rear snap-fit ​​sleeves 5 to accept nails of different lengths, angles, and spacings, thus improving the adaptability of the equipment and reducing the frequency of component replacement. At the same time, due to the adjustability of the snap-fit ​​unit, it can be adjusted according to the state of the nail to improve the compatibility between the snap-fit ​​unit and the nail, avoiding the situation where traditional devices have poor compatibility but can be used with difficulty, resulting in excessive local wear on the snap-fit ​​unit and a reduced service life.

[0022] Preferably, the rotating assembly includes a first mounting plate 12, which is fixedly connected to the inner wall of the front mounting ring 2. The first mounting plate 12 is rotatably connected to a gear 13. The main shaft 8 is coaxially fixedly connected to a gear 14. The gear 13 and gear 14 mesh. The first mounting plate 12 is fixedly connected to a motor 15, which is driven by the gear 13. The motor 15 has a built-in locking unit for locking the gear 13.

[0023] When adjusting the equipment, motor 2 15 controls gear 1 13 to rotate, which causes gear 1 13 to drive the front mounting ring 2 to rotate relative to gear 2 14, thereby causing the front mounting ring 2 to rotate relative to the rear mounting ring 2. After the equipment is adjusted, the locking unit locks gear 13, making gear 13 stationary relative to the first mounting plate 12. During the process of the drive assembly driving the main shaft 8 to rotate, the main shaft 8 drives the front mounting ring 2 to rotate synchronously through gear 2 14 and gear 1 13, thereby making the front and rear mounting rings 2 rotate synchronously.

[0024] Preferably, the push-pull assembly includes a support cylinder 16 coaxial with the mounting ring 2. The mounting ring 2 on the rear side is slidably connected to the inner wall of the support cylinder 16 along the axial direction. A plate 2 17 is fixedly connected to the inner wall of the mounting ring 2 on the rear side. A motor 3 18 is fixedly connected inside the support cylinder 16. The output shaft of the motor 3 18 is drively connected to the plate 2 17. The motor 3 18 is used to push the mounting ring 2 on the rear side to slide along the axial direction of the support cylinder 16.

[0025] The push-pull assembly is used to adjust the axial spacing between the front and rear mounting rings 2 to accommodate nails of different lengths. Its specific working process is as follows: Initial state: The rear mounting ring 2 maintains its initial position along the inner wall of the support cylinder 16. The support cylinder 16 is coaxial with the main shaft 8, providing axial sliding guidance for the rear mounting ring 2. Spacing adjustment trigger: When it is necessary to adapt to nails of different lengths, the control system sends a signal to motor 3 18; after motor 3 18 starts, its output shaft drives the pressure ring 19 to move axially along the main shaft 8 through the transmission structure; the pressure ring 19 generates axial thrust through its contact relationship with plate 2 17, pushing plate 2 17 to drive the rear mounting ring 2 to slide axially along the inner wall of the support cylinder 16; Spacing positioning: When the rear mounting ring 2 moves to a position that matches the length of the nail to be sorted (which can be detected by a displacement sensor or limit switch), the motor 318 stops running, and the rear mounting ring 2 remains in its current position, thus completing the adjustment of the spacing between the front and rear mounting rings 2; Synchronous rotation adaptation: When the subsequent drive component drives the main shaft 8 to rotate, the support cylinder 16 rotates synchronously with the main shaft 8. Due to the sliding connection between the rear mounting ring 2 and the support cylinder 16, it not only rotates synchronously with the support cylinder 16, but also maintains the adjusted axial position, ensuring the stable engagement of the front and rear retaining sleeves 5 with the nails.

[0026] Preferably, the feeding assembly includes a number of connecting rods 20 equal to the number of connecting blocks 6. The connecting rods 20 are fixedly connected to each connecting block 6 and are coaxial with the corresponding slide rod 4. A ball bearing 21 is fixedly connected to the end of each connecting rod 20. A pressing unit is provided inside the mounting ring 2. The pressing unit is used to synchronously press and push all the ball bearings 21 radially along the mounting ring 2.

[0027] The feed assembly controls the synchronous radial sliding of all slide bars 4, adjusting the radial position of the ferrule 5 (and the pins), thereby adapting to different "pin spacing" requirements. Its specific workflow is as follows: Initial state: All slide rods 4 maintain the same radial extension length under the constraint of universal joint 3, and the ball bearings 21 at the end of the connecting rod 20 (fixed to the connecting block 6 and coaxial with the slide rod 4) are in a natural state and are not subjected to the force of the compression unit; Radial position adjustment trigger: When it is necessary to adjust the circumferential spacing of the nails (i.e., the distance between adjacent nails in the circumferential direction), the extrusion unit of the feed assembly is activated; Synchronous compression and sliding of slide bar 4: The compression unit applies synchronous pressure to all slide balls 21 along the radial direction of the mounting ring 2. After the slide balls 21 are subjected to pressure, they transmit the force to the connecting rod 20, which in turn pushes the connecting block 6 to drive the slide bar 4 to slide along the radial channel of the universal joint 3. If the slide bar 4 slides outward: the sleeve 5 moves outward synchronously with the slide bar 4, the radial position of the nail moves outward, and the circumferential distance between adjacent nails increases; If the slide bar 4 slides inward: the sleeve 5 moves inward synchronously with the slide bar 4, the radial position of the nail shrinks inward, and the circumferential distance between adjacent nails decreases; Position locking: When slide bar 4 slides to the target radial position (detected by position sensor), the extrusion unit maintains pressure or locks, so that all slide bars 4 maintain the current extension length, ensuring stable nail spacing during subsequent conveying.

[0028] Preferably, the extrusion unit includes two conical blocks 22 arranged symmetrically front to back. The conical blocks 22 are slidably connected to the main shaft 8 and are coaxially arranged with the main shaft 8. The conical surfaces of the conical blocks 22 face each other. A plate 3 26 is fixedly connected to the inner wall of the mounting ring 2 on the front side. A motor 4 23 is fixedly connected to the end of the plate 3 26 and the plate 2 17 near the conical blocks 22. The motor 4 23 is respectively connected to the conical blocks 22 on the same side for transmission. The motor 4 23 is used to control the conical blocks 22 to slide along the main shaft 8.

[0029] The extrusion unit is the power actuator of the feeding assembly. It achieves synchronous radial extrusion of the sliding ball 21 through the axial movement of the conical block 22. The specific working process is as follows: Initial state: The two conical blocks 22 (symmetrical front and back, with their conical surfaces facing each other) maintain their initial axial position along the main axis 8, and their conical surfaces do not contact the sliding ball 21 or only slightly contact it, and the sliding ball 21 is not subjected to radial force; Extrusion trigger: When it is necessary to drive the slide bar 4 to slide radially, the control system sends a signal to the motors 23 on both the front and rear sides; Axial movement of conical block 22: After the motor 4 23 starts, its output shaft drives the conical block 22 on the same side to slide along the main shaft 8 (the sliding directions of the front and rear conical blocks 22 are opposite, such as the front conical block 22 sliding backward and the rear conical block 22 sliding forward); by utilizing the inclined characteristics of the conical surface, the axial force of the conical block 22 is converted into a radial thrust on the sliding ball 21; Synchronous compression control: The rotation speed and direction of the front and rear motors 23 are kept consistent, ensuring that the axial movement distance of the two conical blocks 22 is the same, and the radial thrust applied to the sliding ball 21 on the front and rear mounting rings 2 is uniform, thereby making the sliding rod 4 on the front and rear mounting rings 2 slide synchronously in the radial direction, avoiding the nail posture deviation due to uneven force. Pressure maintenance and reset: When the slide bar 4 reaches the target position, the motor 4 23 stops running and locks the position of the conical block 22, maintaining the radial pressure on the ball 21; if reset is required (the slide bar 4 returns to its initial extension length), the motor 4 23 rotates in the opposite direction, causing the conical blocks 22 to move away from each other along the axis of the main shaft 8, the radial thrust of the conical surface on the ball 21 disappears, and the slide bar 4 returns to its initial position under the elastic constraint of the universal joint 3 (or the return spring, which is not detailed and is a conventional design).

[0030] Preferably, the drive shaft of the motor 23 is fixedly connected to a screw 24, the screw 24 passes through the corresponding conical block 22 and is threadedly connected to the conical block 22, and the motor 23 is used to control the rotation of the screw 24.

[0031] The specific transmission structure for the motor 23 to drive the conical block 22 to slide is the screw 24 transmission, and the working process is as follows: Transmission structure adaptation: The transmission shaft of motor 23 is fixedly connected to screw 24. Screw 24 passes through tapered block 22 and is threadedly engaged with tapered block 22 (the inner wall of tapered block 22 is provided with internal thread matching screw 24), forming screw 24 and nut transmission pair; Forward drive (conical block 22 approaches): When motor 4 23 rotates forward, it drives screw 24 to rotate synchronously in the forward direction; since the conical block 22 and the main shaft 8 are slidably connected (it can only move axially and cannot rotate circumferentially), the rotation of screw 24 is converted into the movement of conical block 22 along the axial direction of main shaft 8 through threaded engagement (for example, when the front motor 4 23 rotates forward, screw 24 drives the front conical block 22 to slide backward; when the rear motor 4 23 rotates forward, screw 24 drives the rear conical block 22 to slide forward), so that the two conical blocks 22 approach each other and squeeze the sliding ball 21; Reverse drive (conical block 22 moves away): When motor 4 23 rotates in the reverse direction, screw 24 rotates in the reverse direction synchronously. Through the threaded engagement, it drives the conical block 22 to move away from each other along the main shaft 8, and the squeezing effect of the conical surface on the sliding ball 21 is released. Position accuracy control: The screw 24 transmission has the characteristics of high transmission accuracy and small backlash. The motor 23 (preferably a stepper motor or servo motor) can control the rotation angle to precisely control the number of rotations of the screw 24, thereby precisely controlling the axial movement distance of the tapered block 22, and finally achieving precise adjustment of the radial extension length of the slide bar 4, ensuring that the accuracy of the nail spacing meets the production requirements.

[0032] Preferably, the slide rod 4 has a threaded hole at one end outside the mounting ring 2 along the axial direction, and the slide rod 4 is threadedly connected to a threaded rod 25 through the threaded hole. The end of the threaded rod 25 is fixedly connected to the sleeve 5.

[0033] The sliding rod 4 and the ferrule 5 are connected by a threaded connection, mainly used for quick replacement and fine adjustment of the ferrule 5. The working process is as follows: Fitting requirements for ferrule 5: When the "nail body diameter" of the nail to be sorted changes, a ferrule 5 with the corresponding inner diameter needs to be replaced (to ensure that the ferrule 5 can stably hold the nail body). Disassembly of ferrule 5: The operator manually rotates the old ferrule 5. Since the ferrule 5 is fixedly connected to the threaded rod 25 and the threaded hole of the threaded rod 25 is threadedly engaged with the threaded hole of the slide rod 4, rotating the ferrule 5 will drive the threaded rod 25 to unscrew from the threaded hole of the slide rod 4, thus completing the disassembly of the old ferrule 5. Installation of new ferrule 5: Align the ferrule 5 (fixed to the new threaded rod 25) with the threaded hole of the slide rod 4, manually rotate the ferrule 5 to screw the threaded rod 25 into the threaded hole, until the ferrule 5 fits against the end face of the slide rod 4 or reaches the preset tightening torque, and the installation of new ferrule 5 is completed. Fine-tuning of posture: If there is a slight deviation between the axis of the ferrule 5 and the axis of the slide bar 4 after installation (affecting the nail engagement accuracy), the posture of the ferrule 5 can be corrected by slightly rotating the ferrule 5 and using the small adjustment of the thread to ensure that the axes of the front and rear ferrules 5 are collinear; Batch adaptation: Since all slide bars 4 and ferrules 5 have the same connection structure, all ferrules 5 on the front and rear mounting rings can be replaced in batches to quickly adapt to nails of different diameters and improve equipment changeover efficiency.

[0034] Preferably, the drive assembly includes a mounting frame 10, which is fixedly connected to the coil nailing machine. The main shaft 8 is rotatably mounted on the mounting frame 10, and a motor 11 is fixedly connected to the mounting frame 10. The motor 11 is drively connected to the main shaft 8.

[0035] Motor 11 drives main shaft 8 to rotate, main shaft 8 drives support cylinder 16 and gear 14 to rotate, which in turn drives the front and rear mounting rings 2 to rotate synchronously.
