Description

Semi-automatic strapping machine capable of power banding {SEMI-AUTOMATIC STRAPPING MACHINE WITH POWER BANDING}

The present invention relates to a semi-automatic strapping machine, and more specifically, when banding fabric using a packaging PP band, the product is first tied and then the PP band is pulled to provide additional tension, thereby strengthening the packaging object during the power banding process. This relates to a semi-automatic strapping machine capable of power bending that prevents deformation.

In general, packaging banding devices that use strip-shaped bands as tie strings are widely used to bundle and package various types of products in a certain number of bundles rather than individually. Most of these packaging banding devices allow individual products to be bundled and packaged in a certain number of bundles by simply wrapping the band used as a bundle around the outer surface of the packaged object with a certain binding force and cutting the band to bind it.

A semi-automatic strapping machine using a PP band has been developed as a type of packaging banding device. The semi-automatic strapping machine supplies the end of the PP band to the inside of the workbench, fixes it, and retracts the PP band using a tension motor. After the PP band wraps the packaging object with a certain tension, the ends of the PP band are joined and then cut.

However, the conventional semi-automatic strapping machine described above has a problem in that it is not strong enough to bundle elastic products such as fabric in a compressed state when tying inflexible products such as boxes and containers.

Accordingly, press banding machines are used to bind elastic items. The press banding machine compresses the packaging object with a press and then binds the packaging object using a PP band, etc., but it has the problem of high risk due to the press and the packaging object may be deformed due to high pressure.

Meanwhile, Registered Utility Model No. 20-0166005 includes a belt supply mechanism, a strip tensioning mechanism, a pivoting roller carriage that pivots by a supply tension cam, and a belt wrapping device that may be inserted into the belt wrapping device due to interference during the supply of the strip. It includes a banding housing that prevents failure to properly feed the band, and a band deployment housing that accommodates the band being removed from the banding device or the banding housing during tensioning of the band. The pivoting roller carriage first allows the band feeding mechanism to Actuating the strip feeding mechanism to feed such strips towards a belting device that engages with a portion and loops the strips around the package, wherein the strip feeding tensioning mechanism operates a first gripper that secures the ends of the strips in the belting device. After that, the pivoting roller carriage operates so that the strip tension mechanism engages a portion of the strip to apply tension to the loop forming the strip, and if the strip is not properly engaged by the first gripper, the strip tension mechanism uses a belt wrapping device. The strip will then remain in the strip deployment housing until the strip feed mechanism engages a portion of the strip and re-feeds the strip towards the belting device, where the strip will be directed into the strip deployment housing. The weight and position of the strip placed within the deployment housing prevents the strip from being completely withdrawn from the strip feed mechanism, thereby allowing the strip feed mechanism to automatically engage the strip and re-supply the strip to the belt wrapping device. A band supply tensioning device for a strapping machine is proposed and disclosed,
