Abstract

PURPOSE:To perform high-speed bundling by winding tapes in a predetermined position to which the objects to be bundled are sequentially brought down by means of a work receiving portion in a circulating motion which receives a plurality of long works in bundles using its recessed surface facing upwardly and which drops the same using its recessed surface facing downwardly by the circulating motion of a belt. CONSTITUTION:A work P to be bundled is sequentially placed in a lower position A of a conveyor mechanism 10 and carried by the movement of a belt driven by a motor 10F to a higher position B thereof, where a work receiving portion 20Aa2 receives the work P, since its recessed surface faces upwardly and a tape T is extended by the circulating motion of the belt so as to be supported between the retaining face of a tape retaining and severing portion 30Aa and the end portion of a C-shaped arm 30Ab2. The work receiving portion 20Aa2 is moved downwardly by the circulating motion of the belt and a taping means 20A is then placed into motion by the sensor detection, whereby the tape T is wound approximately one-half around the work P and subsequently all around the work P. Thus, a bundle of the work P is made by winding tapes T1 and T2, whereby a high-speed bundling can be performed in a manner extremely similar to manual operation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Use) The present invention relates to a binding device for bundling long workpieces such as green asparagus into bundles.

a2 approaches the tape TIP by the circular motion so as to cover it, and the workpiece bundle P is interposed between the tape T and the concave portion of the workpiece receiving portion 20Aa2.

Here, the workpiece receiving part 20Aa2 moves downward due to the circular movement, and the tape hanging l12 is detected by the sensor.
The OA is activated, and the tape T is wrapped around approximately 1/2 of the circumference of the workpiece bundle P, as shown in FIG. 2(b).

Next, as shown in FIG. 2(C), the tape T is wrapped around the entire circumference of the workpiece bundle P, and the end of the tape T adhering to the holding surface of the tape holding/cutting section 30Aa and the C mold arm 3
The adhesive surface of the tape ■ drawn out by 0Ab2 is attached, and in this state, the workpiece bundle P is 2 as shown in FIG.
This means that the tapes TI and T2 are bound at certain points.

Then, the blade of the C-shaped arm 30Ab2 and the cutting part of the tape holding/cutting part 30Aa come into contact and cut the tape T. At this time, since the work receiving part 20Aa2 is concave downward, the bound work bundle is cut. P is accommodated in the packet 40 directly below it due to natural fall. Then, the state returns to the state shown in FIG. 1 again.

In this case, the work receiving portion 20Aa2 is
