Description

[Detailed Description of the Invention] This invention relates to a method for manufacturing a cage for fruit cultivation.
The purpose of this is to maintain constant pipe spacing even during long-term use, and to maintain good ventilation and drainage.
To provide a method for producing bamboo shoots that can surely prevent fruits such as strawberries, watermelons, and prince melons from rotting.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1A and B/I, the manufacturing method of the present invention involves molding a large number of long pipes 2 (for example, length 180 crL) made of synthetic resin such as polyethylene, polypropylene, vinyl chloride, etc. using an extrusion molding machine 1. Next, as shown in FIG. As shown in the figure, while pulling the thread 3 in its longitudinal direction, the heater 5 (trowel) heats the thread 3 to maintain a substantially constant interval between the pipes 2.
Glue the thread 3 and the pipe 2 while keeping the thread 3
Glue the contact parts.

Particularly in this embodiment, since the thread 3 is heated while being pulled in the longitudinal direction, the adhesive or the like impregnated into the thread 30 oozes out from the upper surface of the thread, thereby improving the adhesive effect.

In addition, by pulling the thread 3, the pipe 2 is compressed by the thread 3 and partially recessed, and the thread 3 is strongly wedged into this recess, which has the effect of making it even more difficult for the pipe 2 to come out.

In addition, when knitting yarn 3, leave 4 threads between pipes 2 and 2, and
It is desirable to twist it two or more times.

Next, as shown in FIG. 1E, the cutter 6 is used to cut an appropriate part of the pipe excluding the excess braided portion 4 to form screens 7, 7 of a predetermined width (for example, 18 crf1.).
As shown in the figure, these screens 7 and groups of 7 are wound around a plurality of drums 8.8 arranged alternately in the vertical direction.

Incidentally, in the above examples, threads that were pre-impregnated or coated with a heat-soluble adhesive or the like were used, but instead of this, after braiding the threads, a heat-soluble adhesive or a thermoplastic synthetic resin was applied to the threads. It may be applied to the surface and then heated and bonded.

The thread 3 is made of a material such as vinylon, cotton, or polypropylene, and the heat-soluble adhesive or thermoplastic synthetic resin impregnated, coated, or applied to the thread is appropriately selected depending on the material of the pipe 2.

In the screen 7 formed by this manufacturing method, as shown in FIG. 2, the distance 1 between the pipes 2, 2 is maintained constant, and the excess knitting portion 4 of the threads 3 is securely held by heat welding.

The bamboo basket 7 has a bed 10 along the planting direction of strawberries, for example.
It is laid on top and receives the fruits 12 of strawberries 11 as shown in FIG.

As described above, in the method of the present invention, after knitting a plurality of synthetic resin pipes with thread, the threads are heated and impregnated with, coated with, or coated with a heat-soluble adhesive or thermoplastic synthetic resin. (Because of this, the threads and pipes are glued together to create the screen, so each pipe will not fall out of the braided threads even during long-term use, and a constant spacing between each pipe will be maintained. Ru.

In other words, if each pipe is simply knitted with thread, the pipes may pull out and fall off, or if the pipes are not evenly spaced and there is a wide gap, the fruit may fall within the space and come into contact with the upper surface of the sleeping bed, causing water droplets to form and rotting. In places with small gaps, a water film is formed due to the surface tension of the water, and this water film causes the fruit to rot, but the bamboo baskets produced by the method of the present invention do not have such drawbacks.

In addition, since the screen does not deform in any way even when used for a long period of time, ventilation and drainage are good.

In addition, threads impregnated with, coated with, or coated with heat-soluble adhesives or thermoplastic synthetic resins are made of materials with low water content, so the threads may rot and tear, making the screen unusable.
In addition, water droplets attached to the threads will not come into contact with the fruit and cause gray mold on the fruit.

In addition, the following improvements may be added to the present invention.

■ Both ends of a synthetic resin pipe are sealed by welding, etc. to prevent pathogens from propagating inside the pipe, and the air present inside the pipe increases the restoring force of the pipe.

(2) A bending line or several bending lines are provided on the pipe Q in a direction perpendicular to the synthetic resin pipe (that is, a direction parallel to the threads) so that the pipe can be bent along these lines.
