  As shown in FIG. 1, the band guide 29 not only has the function of guiding the binding band 28 when the binding band 28 is pulled out forward (toward the handle 23) of the binding work table 2, but also has the following remarkable features. Play a function.

  That is, as described above, when the portion 55 of the binding band 28 behind the lawn bundle 22 is pulled upward as shown in FIG. 4B, the binding band 28 is pulled out from the binding band supply tool 3. , Play the function to guide. Thus, the band guide 29 is a very useful component, and the lawn binding working device 1 and the lawn binding method of the present invention are also characterized in that the band guide 29 is effectively used.

  Then, as shown in FIG. 5 (a), the front end 30 of the binding band 28 and the rear end 57 formed by cutting the folded portion 56, which is the rear portion 55 of the lawn bundle 22, The front end portion 30 and the rear end portion 57 which are overlapped and overlapped are heat-welded by a commercially available hand-held portable heat-welding band binding machine 48. As a result, as shown in FIG. 5B, the lawn bundle 22 is bound by the binding band 28.

  FIG. 6 is substantially the same as the lawn binding method shown in FIGS. 4 and 5, but before cutting the folded-back portion 56 of the binding band 28, the front-end portion 30 of the binding band 28 is bound by the heat welding band binding machine 48. The difference is that the rear portion 55 of the band 28 is thermally welded.

  That is, from the state of FIG. 4A, the rear portion 55 of the grass bundle 22 in the binding band 28 is pulled upward to form the folded portion 56 as shown in FIG. A portion where the front end portion 30 and the rear portion 55 are overlapped is sandwiched by a heat welding band binding machine 48 and thermally welded. Thereafter, as shown in FIG. 6B, the binding band 28 is cut in the vicinity of the folded portion 56 (see the cutting line S indicated by the one-dot chain line in FIG. 6B).

  In addition, when the lawn bundle 22 is bound in a cross shape with the binding band 28, the lawn bundle 22 bound as described above is once lifted, rotated 90 degrees in a horizontal plane, and again placed on the lawn placement unit 21. , Place. And what is necessary is just to repeat said binding work.

  By the way, in the above bundling operation, the lawn bundle 22 to be bundled is placed at least in front of the portion 60 where the bundling band 28 pulled out via the band guide 29 starts to come into contact in the lawn placement portion 21. .

  The length of the binding band 28 from the portion 60 that starts to contact to the portion that is fastened with the fastening piece 24 is at least the wrapping from the rear end of the lower surface of the grass bundle 22 to the upper surface along the front surface in FIG. It is necessary to make the length of the binding band 28 longer. If it is such length, as shown in FIG.4 (b), the front-end part 30 of the binding band 28 can be wound to the appropriate position of the upper surface of the bundle 22 of a lawn.

  For that purpose, the length of the binding band 28 from the portion 60 abutting on the lawn placement portion 21 to the portion fastened with the retaining piece 24 is the binding band 28 wound from the rear end to the upper surface of the bottom surface of the grass bundle 22. The length dimension in the front-rear direction of the upper frame 6 and the handle 23 of the bundling work table 2 may be designed so as to be longer than the length of

  As mentioned above, although the form for implementing the working apparatus for lawn binding and the lawn binding method concerning this invention was demonstrated based on the Example, this invention is not limited to such an Example, Claim It goes without saying that there are various embodiments within the scope of the technical matters described in the scope.

  Since the lawn binding work apparatus and lawn binding method according to the present invention have a relatively simple configuration as described above, not only large-scale lawn farms but also small lawn farmers can easily introduce the system. The work efficiency of the bundling work can be greatly improved.
