Description

AUTO STRAPPING PACKAGING TOOL HAVING CLAMP FIXING APPARATUS

The present invention relates to a tool for automatic strapping packaging, and more particularly, to a tool for automatic strapping packaging used when packaging an article using a plastic band.

The automatic strapping packaging tool is used for packaging items such as boxes through a plastic band in the form of a portable tool. In packaging, the product is first wrapped with a plastic band to make a loop, and then the plastic band is pulled through an automatic packing tool until a certain amount of tension is generated in the loop. Then, proceed with the subsequent process of bonding the plastic band of the two-layered overlapping part. Here, the bonding usually uses frictional heat generated by vibration while the plastic band is pressed. As a result, a strong bond between homogeneous materials is generated in the plastic band that is in a locally molten state. Then, when the joint is cooled, a rigid loop is formed.

Conventional tools for automatic strapping packaging have the inconvenience of maintaining a state in which the clamp is spaced apart from the feed wheel at a predetermined interval during the mounting process of the plastic band, which is the first step of strapping. This causes inconvenience to the user in operation, and when the operation continues for a long time, it becomes a problem of lowering the operation convenience.

In addition, conventional strapping and packaging tools are usually used in a way to place and control one long cylindrical BLDC motor. This has become a problem in that the internal structure is complicated, and high vibration is transmitted to different devices during the welding process, which adversely affects the durability of the internal parts. In addition, the long cylindrical BLDC motor imposes restrictions on the arrangement structure of the parts, resulting in an imbalance in the overall weight distribution, raising inconvenience in terms of ease of use.

Meanwhile, while the lever unit 500 is switched to the open mode, the clamp unit 230 is opened by pivoting around the feed wheel unit 220 . In the open mode, the locking jaw of the first locking piece 520 is caught by the first locking element 410 and the lever body 510 is fixed at that position. At this time, the lever shaft 531 is also rotated by the same angle, which rotates the annular ring portion 240 through the connecting piece 610 . As a result, the clamp part 230 spreads from the feed wheel part 220 and is fixed and opened in that state.

Specifically, the lever unit 500 may include a lever body 510 , a first locking piece 520 , an extension locking member 530 , and the like. The lever body 510 has a handle formed at one end, and a shaft hole 511 is formed at the other end to be rotatable. In addition, a coil spring is disposed on the lever body 510 . The lever body 510 rotates at a certain angle by a pulling operation by the user, and when the pulling is released in that state, the lever body 510 returns to its original position by the elastic restoring force of the coil spring. The first locking piece 520 extends outward from the lever body 510 and has a locking protrusion formed at an end thereof.

The extension locking member 530 is coupled to the other end of the lever body 510 and is released from the second locking element 420 when the lever unit 500 is switched to the open mode.

FIG. 6 is a view showing a process in which the clamp part is fixed by the operation of the locking part and the lever part of FIG. 1 , and FIG. 7 is a view showing the rotation of the clamp part in the process of FIG. 6 . In FIG. 6( a ), the lever unit 500 has a second locking piece 532 caught on the second locking element 420 . At this time, the clamp part 230 is close to (or partially in contact with) the feed wheel part 220 as shown in FIG. 7(b). This is called closed mode. First, for strapping, the plastic band has a process of being inserted into the tension module 200 . 6(b) and 6(c), the user first presses the push button bar 411 so that the first locking element 410 is rotated at a predetermined angle. Then, the user provides a pulling action to the lever body 510 so that the end of the first locking piece 520 , that is, the locking jaw is engaged with the first locking element 410 .

At this time, even if the user releases the pulling operation for the lever body 510, the lever body 510 maintains the latched state. In addition, the extension locking member 530 rotates in conjunction with the pulling operation of the lever body 510 , and as a result, the second locking piece 532 is released from the second locking element 420 .

In addition, in conjunction with the pulling operation of the lever body 510, the clamp unit 230 is rotated based on the second axis (a2). As a result, as shown in FIG. 7( a ), the clamp unit 230 moves away from the feed wheel unit 220 , and the clamp unit 230 is fixed in that state. That is, it is switched from the closed mode to the open mode. At this time, a plastic band may be inserted into the tension module 200 . Specifically, the connecting piece 610 rotates the annular annular ring portion 240 engaged therewith, and the annular ring portion 240 rotates the clamp portion 230 through the protruding piece 242 .

On the other hand, in order to switch from the open mode back to the closed mode, the user presses the first locking piece 520 downward. At this time, the first locking element 410 rotates at a predetermined angle, and the lever unit 500 returns to its original position by the elastic restoring force of the coil spring. On the other hand, in the process, the connecting piece 610 rotates the annular ring part 240 in the reverse direction. As a result, the clamp portion 230 is brought into proximity (or partially in contact with) the feed wheel portion 220 .

The tensile module 200 and the welding module 300 according to an embodiment are formed in module units, and are individually driven and controlled. That is, the tension module 200 and the welding module 300 are completely separated from each other and operate independently. This improves product productivity and maximizes assembly efficiency.

The strapping process by the automatic strapping packaging tool is as follows. First, the plastic band is provided with a tensile force of a preset size due to the first power generated by the first motor 210 . Through this, the step of providing the tensile force is completed. Then, the welding module 300 is operated for welding. The welding step starts with the operation of the opening/closing unit 350 . In this case, when the connecting rod part 356 is lowered by the third power by the third motor 351 , the friction providing unit 310 in the open state is switched to the closed state. Then, the friction providing unit 310 linearly reciprocates by the second power by the second motor 311 to provide frictional force to the plastic band applied through the tension module 200 . As a result, the plastic band overlapped in two layers between the inner gripper part 323 and the lower gripper part 329 is locally melted and joined.

In the above, preferred embodiments of the present invention have been exemplarily described, but the scope of the present invention is not limited only to such specific embodiments, and can be appropriately changed within the scope described in the claims.
