In the above-mentioned configuration, when the expanded leaf portions 2' of each of the leafy vegetables 2 such as cabbage and Chinese cabbage, which are growing in large numbers, are lightly tied with vinyl strings 9, for convenience of explanation, in order to perform the bundling in a recycled manner. To explain from the intermediate process in FIG. 6, the vinyl string 9 is passed between the string chucking device 26 of the string binding device 13 of the expansion/contraction compass 7 of the compass 3 expanded to a predetermined size and the slit 23 of the fixed compass 4. Compass 3 while traversing the front side of the confectionery spreading section 2'
The sled-shaped guide 14. is pushed forward from the front side.
14, the expansion/contraction compass 1 opens relative to the fixed compass 4 around the pin 6, expands to the diameter of the expanded leaf portion 2', and passes through the expansion/contraction device 15. 12 is in a state where electricity is cut off, both motors 20 and 12 rotate freely, the compass 3 expands, and as shown in FIG. 9 is pulled from the slit 23 and rotates freely, and the vinyl string 9 is sent out from the string roller 10. At this time, due to the extension of the arm 16 of the compass 3, the diameter is measured via the bevel gear 19. The device @21 measures the diameter of the expanded leaf portion 2', the control device 8 immediately calculates the circumference of the expanded leaf portion 2', and the reversible motor 12 lets out the string 9 by the length L of the circumferential portion. As shown in FIG. 7, the tip of the compass 3 passes through the spreading part 2', and the vinyl string 9 between the chuck device 26 and the slit 23 moves halfway around the spreading part 2'. be done.

Then, at the timing when the pin 6 of the compass 3 reaches the end of the expanded leaf part 2', the motor 20 of the string binding device 15 is operated at a predetermined timing via the control device 8, and the arm 16 is shortened, and the expansion/contraction compass 7 When the fixed compass 4 approaches the pin 6 as shown in FIG. 8, the compass 3 closes to surround the expanded leaf portion 2'.

Then, when the string binding devices 13 and 13 of the compass 3 come into contact with each other and the microswitch 24 detects the closed position,
Once the chuck device 26 is expanded, the concave groove of the string tying device 13 is opened.
As shown in FIG. 10, the heaters 27 and 27 are activated to thermally weld and bond the two threads 9, 9 together. Along with this, the chuck device 26 chucks the base end portion of the string 9 from the closed string roll 10.

Prior to this, the control device 8 makes the length of the circumferential portion of the expanded leaf portion 2' measured by the diameter measuring device M21 a certain amount shorter than the length of the string 9 sent out, and rotates the reversible motor 12 in the reverse direction to roll the leaf. 11 and 11 are reversed, the string 9 is pulled and the string 9 is lightly tightened against the circumferential portion of the expanded leaf portion 2', and welding is performed by the heater 27 in this tightened state.

Then, when the heater 27 is continuously energized for a predetermined period of time, the solenoid type cutter 29 extends and cuts the welded string 9 as shown in FIG.

Then, the motor 2G of the expansion/contraction device rotates and the bevel gear 1
9. Pinion 18. The arm 16 is extended via the rack 17, and the compass 1 is expanded via the pin 6. At this time, the compass 3 is expanded by the chuck device 26 at the tip of the compass 7, as shown in FIG. As shown in Figure 5, by pulling this in the chucked state, the string 9
is pulled out from the slit 23 of the other stationary compass 4, and at this point, the reversible motor 12 is de-energized and the roller 11.11 rotates freely, and the Mi9 is sent out by the force of the force as shown in FIG. Like, scaling compass 7
and the fixed compass 4 in a loose state.

When the compass 3 expands to a size D' that slightly exceeds the diameter of the expanded leaf part 2', the compass 3 is drawn upward from the expanded leaf part 2' as shown by the white arrow, as shown in FIG. It is pulled up and returned to the front side, and becomes an open position. Here, the compass 3 is placed facing the expanded leaf part 2' of the next leafy vegetable 2, as shown in Fig. 13, and pushed forward. As a result, the string 9 loosely stretched between the expansible compass 7 tip and the fixed compass 4 tip is pressed against the inner part of the front side of the expanded leaf part 2', and the sled-shaped guide 14.14 is attached to the expanded leaf part 2'. ', and the process shown in FIG. 6 is reached, and by repeating the above process, each leaf vegetable 2 is sequentially tied to the expanded leaf part 2'.

At this time, in the process of pressing the string 9 against the front half of the expanded leaf portion 2' shown in FIG. .

In this process, the pressing of the FB 9 against the expanded leaf portion 2' and the passage of the compass 3 through the expanded leaf portion 2' are performed in a posture with sufficient leeway by freely pulling out the string 9 from the string roll 10. In addition, when tying, as described above, the control device 8 reversely rotates the reversible motor 12 to appropriately tighten the strings 9.

In addition, since the size of the expanded leaf part 2' accompanying the growth of the leafy vegetables 2 is not necessarily uniform, the amount of sending out and the amount of pulling back of the string 9 by the reversible motor 12 can be freely adjusted each time via the control device 8 at the time of tying. By adjusting the binding, it is possible to optimally tie the leafy vegetables 2 to the expanded leaf portion 2' without loosening or over-tightening.

That is, as shown in FIG. 14, by pulling back the string 9 by reversing the reversible motor 12, the bundle can be tightened, and as shown in FIG. 15, the amount of feed can be increased. This allows binding in a loose state.

Of course, the practical aspects of this invention are not limited to the above-mentioned embodiments. For example, when binding strings, other than heat welding, mechanical tying such as a binding device of a combine harvester or a binder can be used. There are many possible ways in which this can be done.

Furthermore, the target leaf vegetables are not limited to cabbage and Chinese cabbage, but it is also possible to apply the present invention to other leaf vegetables such as spinach.

<Effect of the invention> As mentioned above, according to this invention, basically cabbage.

Since the spreading part of leafy vegetables such as Chinese cabbage can be tied automatically and continuously with vinyl strings, etc., it is possible to make the leafy vegetables grow into desired lumps as commercial products. , it is possible to increase the product value, and
This has the effect of improving work efficiency and leading to increased productivity.

Furthermore, since the leaf vegetables can be bundled as designed, it is easy to stuff them into cardboard boxes or the like after harvesting, and to pack them, which improves the efficiency of shipping operations and has the advantage of increasing productivity.

In addition, since the bundling can be performed uniformly and with uniform precision on the leaf-spreading parts of leaf vegetables, the leaf-spreading parts of the leaf vegetables are not damaged and a decrease in commercial value can be prevented.

One side of the compass is inserted with the string from the string roll, and the other side of the compass has a chuck device, so that the string can be tightened each time the compass expands and contracts during the next stage of tying after the previous stage of tying. It has the advantage that it can be stretched over the expanded leaf part of the leafy vegetable, the string can be traversed through the expanded leaf part via a compass, and the string can be tied.

In addition, by equipping the compass expansion/contraction device with a set length adjustment device via a diameter measurement device, the design length can be adjusted from the circumference of the expanded leaf part when the compass measures the diameter of the expanded leaf part of the leaf vegetable. Since the string can be sent out long or short, the excellent effect of being able to freely adjust the tightness when tying the leafy vegetables to the expanding portion is achieved.
