Technical Field

[0001] This utility model relates to the field of binding technology, specifically to a rubber band transfer device and binding machine. Background Technology

[0002] Rubber bands are widely used in daily life, such as for bundling seafood, packaging goods, and tying common items like food, flowers, and cash. To reduce manual labor and improve automation efficiency, bundling machines are now primarily used to use rubber bands to tie items together.

[0003] Existing strapping machines rely on complex robotic arm structures, achieving high-efficiency strapping by setting multiple grippers on the main shaft. These machines typically have three or four grippers, resulting in a large overall size and limited application scenarios. Furthermore, the multiple grippers on the same main shaft place a heavy load on the motor driving the shaft, reducing its rotation speed and consequently slowing down the feeding of rubber bands, thus affecting strapping efficiency.

Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0024] In order to increase the feeding speed of the rubber band 20 while reducing its size, this embodiment discloses a strapping machine 10. Please refer to... Figure 1 , Figure 1 This is a schematic diagram of the structure of a strapping machine 10 disclosed in this embodiment. The strapping machine 10 is a cuboid, and its interior is equipped with a cutting device 100, a rubber band transfer device 300, and a strapping device 200. The cutting device 100, the rubber band transfer device 300, and the strapping device 200 can all be fixed on the base of the strapping machine 10, which can refer to the base plate of the strapping machine. The cutting device 100 cuts the rubber tube to obtain rubber bands. The rubber band transfer device 300 transfers the cut rubber bands to the strapping device 200, and the strapping device 200 uses the rubber bands 200 to strap the items. A strapping opening is provided on the outer shell of the strapping machine 10, and a gripper is provided on the strapping device 200. After the gripper takes the rubber band 20, it is strapped at the strapping opening.

[0025] Further, see Figure 2 This is a schematic diagram of the internal structure of the strapping machine 10. The diagram illustrates the positional relationship between the cutting device 100, the rubber band transfer device 300, and the strapping device 200. There is a certain distance between the cutting device 100 and the strapping device 200. Since the purpose of this design is to reduce the size of the strapping machine 10, the design aims to minimize the number of grippers on the strapping device 200 and reduce the sliding distance of the strapping device 200. To achieve this goal, the rubber band transfer device 300 is set between the cutting device 100 and the strapping device 200, which can quickly transfer the rubber band 20 and avoid the need to set up multiple grippers and rotate multiple grippers to grab the rubber band 20.

[0026] The cutting device 100 is equipped with a discharge port. The rubber band 20 exits from the discharge port at the discharge point. For the rubber band transfer device 300 to acquire the rubber band 20, the clamping component 330 capable of gripping the rubber band 20 needs to be moved to this position. Therefore, the position where the clamping component 330 grips the rubber band 20 is set as the initial position 31. The binding device 200 needs to acquire the rubber band 20 from the rubber band transfer device 300. The binding device 200 is equipped with a gripper. The binding device 200 acquires the rubber band 20 from the rubber band transfer device 300 by gripping it. During gripping, the gripper is retracted, and the end of the gripper can be inserted into the rubber band 20 to acquire it. When the binding device 200 uses the rubber band 20 for binding, it opens the gripper for binding. The position where the gripper on the binding device 200 grips the rubber band 20 is set as the target position 32. Since the function of the rubber band transfer device 300 is to transport the rubber bands 20 cut by the cutting device 100 to the binding device 200, the rubber band transfer device 300 needs to reciprocate between the cutting device 100 and the binding device 200. Understandably, within the binding machine 10, due to the different positions of the cutting device 100 and the binding device 200, simply sliding or rotating may not be sufficient to transport the rubber bands 20. To ensure the rubber bands 20 can be gripped, the rubber band transfer device 300, through sliding and rotating, can accurately move the gripping component 330 to the initial position 31 and the target position 32, precisely transporting the rubber bands 20 between them. The rubber band transfer device 300 is equipped with the gripping component 330 to grip the rubber bands 20, while the first sliding component 310 and the rotating component 320 are provided to enable the sliding and rotating of the gripping component 330.

[0027] In an optional embodiment, see Figure 2-3To better bundle the product and avoid damage to or limitations caused by the bundling machine 10 during the bundling process, the bundling device 200 maintains a certain distance between the bundling opening and the bundling device 200. The bundling device 200 is equipped with a second sliding component 210, which allows it to slide from the target position 32 to the bundling opening for bundling. The second sliding component 210 includes a second base 211 and a second slide rail 212. In this design, to reduce unnecessary motors, the motor driving the elastic band transfer device 300 is omitted; instead, the sliding bundling device 200 drives the elastic band transfer device 300. The connector 400 on the elastic band transfer device 300 connects to the bundling device 200, making the structure lighter and further reducing the size of the bundling machine 10. In this design, the motor drives the bundling device 200 to slide back and forth along the second sliding component 210, and the connector 400 drives the first sliding component 310 to slide. Understandably, connector 400 can be configured as a connecting rod, connecting plate, cam, or other structure.

[0028] In an optional embodiment, see Figure 3 The connecting member 400 is configured as a curved groove plate 410, which has a curved groove 420. A guide pin 340 is mounted on the first base 311 and can be inserted into the curved groove 420. When the curved groove plate 410 is driven by the binding device 200, the guide pin 340 can slide within the curved groove 420. The groove wall within the curved groove 420 exerts a thrust on the guide pin 340, causing the guide pin 340 and the first base 311 to slide on the first slide rail 312, thereby causing the entire elastic band transfer device 300 to begin sliding. Using a curved groove plate 410 for the connecting member 400 is more stable and flexible than using a connecting rod or cam structure.

[0029] Further, see Figure 4 The curved groove 420 is provided with an inclined groove 421, a first straight groove 422, and a second straight groove 423. When the curved groove plate 410 pushes the guide pin 340 to move, the movement is mainly achieved by the thrust generated by the inclined groove 421 on the guide pin 340. When the rubber band transfer device 300 slides between the initial position 31 and the target position 32, the sliding distance is a fixed distance. Therefore, the inclined groove 421 has a preset length. Within this preset length, the guide pin 340 is pushed, and the rubber band transfer device 300 can move within the initial position 31 and the target position 32. That is, the sliding distance of the rubber band transfer device 300 is determined by the preset length of the inclined groove 421.

[0030] Furthermore, the curved groove 420 also includes a first straight groove 422 and a second straight groove 423, which are respectively connected to both ends of the inclined groove 421. The connection point between the first straight groove 422 and the inclined groove 421 is a second preset position 425. When the guide pin 340 slides to the second preset position 425 in the curved groove 420, the clamping component 330 moves to the target position 32. The connection point between the second straight groove 423 and the inclined groove 421 is a first preset position 434. When the guide pin 340 slides to the first preset position 424 in the curved groove 420, the clamping component 330 moves to the initial position. When the strapping device 200 slides towards the strapping opening, the gripper passes through the target position 32 and catches the rubber band 20 at the target position 32. However, since the strapping device 200 is connected to the first base 311 through the connector 400, when the strapping device 200 slides, it will cause the clamping component 330 to slide. Therefore, to ensure that the clamping component 330 remains stationary at the target position 32 when the strapping device 200 moves to the target position 32, and to keep the clamping component 330 at the target position 32 for a first preset time, a first straight groove 422 is provided in the curved groove 420. The length of the first straight groove 422 is relatively short, only ensuring that when the strapping device 200 slides towards the strapping opening and is fully inserted into the rubber band 20, the guide pin 340 will not be subjected to force in the first straight groove 422, and the clamping component 330 will remain at the target position 32 without moving. Within the strapping machine 10, due to the different volumes of the components and the different settings of the target position 32, the distance that the strapping device 200 slides on the second sliding component 210 will be different from the distance that the first base 311 slides on the first slide rail 312. Therefore, when one device slides, the other device needs to stop sliding. Furthermore, when the clamping component 330 moves to the initial position 31, it needs to stay at the initial position 31 for a second preset time to ensure that the rubber band 20 can be clamped. The elastic band transfer device 300 is slidable by the binding device 200, preventing a situation where the elastic band transfer device 300 slides while the binding device 200 remains stationary. If the binding device 200 needs to move further when it has moved enough to move the elastic band transfer device 300 to the initial position 31 or the target position 32, the second straight groove 423 allows the guide pin 340 to slide within it without being subjected to force. In this case, the clamping assembly 330 can remain at the initial position 31 for a second preset time. Furthermore, the second straight groove 423 allows adjustment of the sliding distance between the binding device 200 and the elastic band transfer device 300, ensuring they each meet the desired sliding distance.

[0031] A groove 430 is also provided on the curved groove plate 410. The groove 430 is located on the edge of the curved groove plate 410 and cooperates with the positioning post on the binding device 200. When the binding device 200 slides, the positioning post abuts against the edge of the groove 430, which drives the curved groove plate 410 to slide. This arrangement can also adjust the sliding distance between the binding device 200 and the elastic band transfer device 300, and can also extend the time that the clamping assembly 330 stays in the initial position 31 or the target position 32. Furthermore, the curved groove plate 410 is connected to the binding device 200 through the positioning post. In order to make the curved groove plate 410 slide more stably between the binding device 200 and the elastic band transfer device 300, the binding device 200 is also provided with a third slide rail 442 and a third base 441. The third slide rail 442 is arranged parallel to the second slide rail 212, and the third base 441 slides along the third slide rail 442. The third base 441 is fixedly connected to the curved groove plate 410. The third slide rail 442 and the third base 441 enable the curved groove plate 410 to slide more stably under the drive of the binding device 200.

[0032] In this embodiment, see Figure 5 The first slide rail 312 and the second slide rail 212 are perpendicular, meaning the sliding path of the binding device 200 is perpendicular to the sliding path of the first base 311. To make it easier for the curved groove plate 410 to push and pull the guide pin 340, the inclination direction of the inclined groove 421 is set at a 45° angle. The angle between the inclined groove 421 and the first straight groove 422 or the second straight groove 423 is 45°. Thus, when the binding device 200 slides from the target position 32 toward the binding opening, the clamping component 330 slides from the target position 32 toward the initial position 31 to clamp the rubber band 20 at the initial position 31; when the binding device 200 slides from the binding opening toward the target position 32, the rubber band transfer device 300 slides from the initial position 31 toward the target position 32 to transport the rubber band 20 to the target position 32. According to the rubber band transfer device 300 disclosed in this embodiment of the present invention, see [link to relevant documentation]. Figure 6 The rubber band transfer device 300 also includes a clamping assembly 330 and a rotating assembly 320. The rotating assembly 320 controls the rotation of the clamping assembly 330, aligning the clamp 331 on the clamping assembly 330 with the target position 32 or the initial position 31. The rotating assembly 320 includes a gear 321 and a rack 322. The rack 322 is mounted on the base plate of the first slide rail 312. The gear 321 slides with the first base 311. When the gear 321 slides, it meshes with the rack 322, causing the gear 321 to rotate. The gear 321 is coaxially arranged with the clamping assembly 330, and the rotation of the gear 321 causes the clamping assembly 330 to rotate accordingly.

[0033] In an optional embodiment, the clamping component 330 rotates at an angle of 180°. However, it is understood that the angle of rotation of the clamping component 330 can be changed to other angles depending on the internal structure of the strapping machine 10.

[0034] According to the clamping assembly 330 disclosed in this embodiment of the present invention, the clamping assembly 330 can be configured as a pneumatic finger or a mechanical gripper. See also Figure 7 This solution uses a mechanical gripper, specifically including a gripper 331 for gripping the rubber band 20, and a switch 332 for controlling the opening and closing of the gripper 331.

[0035] Further, see Figure 8 The base plate of the clamping assembly 330 is provided with a groove 334. The switch 332 is a slider 332a that can slide within the groove 334. Under normal circumstances, the end of the slider 332a protrudes outward for easy pressing. The clamp 331 consists of a fixed arm 331a and a movable arm 331b. The movable arm 331b moves closer to the fixed arm 331a to clamp it. When the movable arm 331b moves away from the fixed arm 331a, it can easily grip the rubber band 20, and the rubber band 20 can easily be fitted onto the fixed arm 331a. A torsion spring 333 is connected between the movable arm 331b and the slider 332a. When the slider 332a slides into the groove 334 under force, the torsion spring 333 pushes the movable arm 331b, which can open the clamp 331. When the slider 332a is no longer under pressure, the torsion spring 333 springs back, and the clamp 331 closes.

[0036] Furthermore, participate Figure 2 The sliding frame 110 is located at the discharge port of the cutting device 100, on the outer periphery of the discharge port. The cutting device 100 cuts the rubber tube by sliding the blade holder in cooperation with the blade. The sliding frame 110 is connected to the blade holder, and when the blade holder slides, the sliding frame 110 slides along with it. When the clamping assembly 330 reaches the initial position 31, the blade holder moves away from the blade, and the sliding frame 110 can abut against the slider 332a. The clamp 331 opens, ready to clamp the rubber band 20. When the cutting device 100 cuts, the blade holder slides towards the blade, and the sliding frame 110 slides along with the blade holder, causing the sliding frame 110 to separate from the slider 332a, and the clamp 331 clamps. Since the clamp 331 clamps during the cutting process of the cutting device 100, it can just clamp the cut rubber band.

[0037] Furthermore, an inclined surface 332b is provided on the slider 332a. When the cutting device 100 cuts, the sliding frame 110 moves to the right and separates from the slider 332a. The inclined surface 332b can slow down the separation of the sliding frame 110 and the slider 332a, thus providing a buffering effect.
