Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for removing joint 7 lunges of a pot for raising seedlings formed by connecting a large number of synthetic resin sheets through joint flanges having fragile connecting parts.

Conventionally, in pots made of a chain of pots for raising seedlings, cuts were made at predetermined intervals at the joints of each pot, so after filling each pot with soil, When cutting out the pots, it was difficult to cut them out along the cuts, and each pot had to be cut out individually, which was time-consuming and the cuts were not beautiful.

The present invention is applied to each of a large number of pots for raising seedlings, which are formed by vacuum forming a synthetic resin sheet, arranged in a plane such as a base, and connected to each other via joint flanges provided with fragile connecting parts. The object of the present invention is to provide a method for removing a joint flange of a pot for raising seedlings, which can extremely efficiently remove the joint flange, which becomes unnecessary, from each pot after filling each pot with soil.

Next, each embodiment of the present invention will be described based on the drawings.

First, a first embodiment of the present invention will be described with reference to the drawings from FIG. 1 to FIG. 8.

In the figure, reference numerals 1 to 1 are pots for raising seedlings in the shape of an open top. connected.

The pot 1 and the joint flange 2 are formed by vacuum forming or the like using a thin plastic sheet such as polyethylene, and the boundary between the upper edge of the pot 1 and the joint flange 2 is formed by four fragile Connecting part 3
It is separated by leaving a cut 4.

That is, each pot 1-1 is connected to a joint flange 2 by four frangible connections 3, respectively.

Reference numeral 5 designates drainage holes provided through the bottoms of the pots 1 to 1, respectively.

Reference numeral 6 denotes a joint flange remover, in which a large number of press rods 8 with push pieces protrude below a lattice-shaped substrate T made of light alloy material, iron material, hard plastic, or the like.

The arrangement of the press rods 8 with push pieces is almost the same as the arrangement of the pots 1.

Next, the joint flange removal method of this example will be explained.

A large number of pots 1 to 1 arranged in a plane and connected by jointed flanges 2 at their upper edges is called a multi-pot.Soil is placed on top of the multi-pot as shown in Fig. 3, and each pot is After filling soil into the chamber, scrape off the excess soil remaining on the top with a flat scraping board as shown in Figure 4, and flatten the top surface.Next, remove the joint flange as shown in Figure 5. When the pressing rods 8 to 8 with push pieces of the container 6 are inserted into each of the pots 1 to 1 and pressed downward as shown in FIG. H is generated and each pot 1 to 1 is pressed onto the workbench F.

Next, when the end E of the joint flange 2 and the end of the grid-like substrate 7 of the joint flange remover 6 are pinched together and pulled upward, the joint flange 2 is pulled up together with the board 7, as shown in FIG. The fragile connections 3 to 3 are successively torn off and pulled up, and the pots 1 to 1 remain on the workbench F in an aligned state as shown in FIG.

Note that the recess H formed on the inner upper surface of each pot 1 is convenient for planting seeds and seedlings.

According to this example, each pot 1 is connected to the joint flange 2 only by the fragile connecting portion 3, and the joint flange 2 is pulled up while pressing the pot 1 with the push rod 8, so that the joint flange 2 is moved from the pot 1. It has the feature that it can be easily separated.

Next, a second embodiment of the present invention will be described with reference to FIGS. 9 and 10.

In this example, a large number of pressing rods 8A-8A with push pieces are installed on the circumferential surface of a cylindrical rotating body 9, and the rotating body 9 is rotatably supported by a holder 10.

In this example, the rotating body 9 supported by the holder 10 is connected to the pot 1.
Rotate at the top of ~1.

When the rotating body 9 is rotated by appropriately hooking the end E of the joint flange 2 to the holder 10, for example, the pressing rods 8A to 8A with push pieces of the rotating body are sequentially inserted into the pots 1 to 1. This creates a recess H in the soil inside, and the joint flange 2 can be separated from the pot 1 at the fragile connection part 3 and rolled up.

As described above, in the present invention, soil is poured into a large number of pots for raising seedlings that are arranged in a plane and connected through joint flanges provided with fragile connecting portions, and then a pressing member having a pressing rod with a pressing piece is placed. Therefore, the joint flanges were pulled up while pressing the soil in each pot, the weak connecting parts were cut, and the joint flanges were removed from each pot, leaving each pot intact.
It has the advantage that the connecting flanges connecting each pot can be removed extremely efficiently and easily.
