Japanese Utility Model Publication No. 54-70842 JP-A-2005-65522

The structure of the sheet laying device will be described using the basic structure proposed by the present applicant. FIG. 3 is a schematic view showing the structure of the sheet laying apparatus.
The sheet laying device includes a sheet reel 1R that holds the sheet 1, a punching device 2, a pressure-reducing roller 3, an earthing disk 4, a seed tape reel 5R that holds a seed tape 5, a seed detector 6, a punching control circuit 7, and a seeding pipe 8. It has.

FIG. 4 is a perspective view showing the structure of the punching device of the simultaneous punching sheet laying device.
4 includes a blade 9 having a plurality of triangular cutting edges, a holding frame 10 that forms the blade 9 in a U-shape, and a reciprocating motion of the holding frame 10 in a direction in which the blade 9 pushes the sheet 1 away. A driving means 11 for causing the blade 9 to push out the sheet 1, a receiving base 12 for preventing the sheet 1 from escaping, a folding plate 13 for folding back a U-shaped opening piece 16 (see FIGS. 5 and 6) of the sheet 1, and It is composed of a folding bar 14. Such a folding bar 14 is not used in a conventionally known apparatus.

FIG. 5 is a schematic view for explaining the operation of the simultaneous punching sheet laying apparatus.
FIG. 6 is a schematic diagram for explaining the operation sequence of the punching device of the simultaneous punching sheet laying device.
The sheet 1 moves down the upper surface of the cradle 12 by pushing down the folding plate 13 ((A) in FIG. 6). When the seed detector 6 detects the seed 15, it receives the output signal of the drilling control circuit, the driving means 11 is actuated, the blade 9 pushes the sheet 1 into a U-shape, and the U-shaped opening piece 16 that has been cut off. Is folded by the folding plate 13 ((B) of FIG. 6).
The folded opening piece 16 is further folded by the folding rod 14 ((C) of FIG. 6).

On the other hand, as shown in FIG. 5, the seed tape 5 passes through the seed detector 6 and is buried from the seeding pipe 8 to a predetermined depth from the soot surface. When the seed detector 6 detects the seed 15 in the seed tape 5, it sends the detection signal to the drilling control circuit 7, and the drilling control circuit 7 outputs a signal for driving the driving means 11 of the drilling device 2. On the other hand, when the sheet 1 passes through the punching device 2, the driving means 11 is actuated to make a U-shaped hole, and the U-shaped opening piece 16 is folded back by the folding plate 13 and the folding rod 14. Then, the sheet 1 is laid by covering the surface of the eaves through the pressure reducing roller 3 and covering the soil with the earthing disc 4 at both ends of the sheet 1.
It should be noted that the opening position of the sheet 1 and the seed position of the seed tape 5 are matched with each other because the distance A between the opening position of the sheet 1 and the punching device 2 and the distance between the seed 15 of the seed tape 5 and the seed detector 6. It is established by matching B.

In the above-described simultaneous punching sheet laying device, since the opening piece 16 of the sheet 1 is laid in a folded state, the folded opening piece 16 is turned over to the surface of the sheet 1 due to the influence of strong wind. There was a bug. Such a state in which the aperture pieces 16 are turned over may hinder the growth of the crop, and is a factor that hinders productivity.
An object of the present invention is to provide a sheet laying device that can prevent a folded opening piece from turning over to the sheet surface due to the influence of strong wind by gluing and bonding the folded opening piece of the sheet. The object is to provide a drilling device.

In order to achieve the object, a punching device for a sheet laying device according to claim 1 according to the present invention is provided.
In the drilling device used for the sheet laying device that draws and lays the seed tape and polyethylene sheet at the same time,
A blade that forms an aperture piece by cutting the sheet leaving a bent portion upstream of the cut aperture;
A holding frame that supports the blade;
A container having an application part for supplying glue to one end and provided in the holding frame;
Drive means for raising and lowering the holding frame;
A cradle for preventing the escape of the sheet when the blade pushes through the sheet;

A folding rod provided on the holding frame so as to be swingable, and folding back the hole piece to the sheet on which the glue is applied, and pressing and gluing the glue piece;
A pressure-reducing means for inverting and laying the sheet on the ridge so that the hole piece folded and bonded by the folding rod is positioned on the heel side of the sheet to be laid;
With
The sheet presses down the folded plate and moves on the upper surface of the cradle, and when the seed tape is detected, the driving means lowers the holding frame and pushes the sheet with the blade to open the hole piece. The one end of the container that has been lowered and pressed against the sheet is coated with glue, the folded plate folded the hole piece at the folding portion, and the hole piece folded the folding bar Is adhered to a sheet coated with the glue.

A punching device for a sheet laying device according to claim 2 according to the present invention is the punching device for a sheet laying device according to claim 1,
The blade has a plurality of triangular cutting edges, and is held in a U shape on the holding frame,
The container has an application part that permeates and discharges glue at the lower end, and is configured to be fixed to the holding frame so as to be movable up and down integrally with a holding bracket .

  The punching device of the sheet laying device according to the present invention can prevent the opening piece from being turned up due to the influence of strong wind by gluing and bonding the opening portion of the sheet in a folded state.

Embodiments of an apparatus according to the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view showing an embodiment of a punching device for a sheet laying device according to the present invention.
The holding frame 10 of the drilling device 2 is supported by the driving means 11 so as to be movable up and down with respect to the cradle 12, and the holding frame 10 has an application portion that permeates and discharges glue 17 (see FIG. 2) at one end. A container 19 having 18 is fixed by a holding metal fitting 20. At the same time as the blade 9 supported by the holding frame 10 pushes down the sheet 1, the paste 17 is applied to the approximate center position where the applicator 18 overlaps when the opening piece 16 of the sheet 1 is folded back.

The folding plate 13 constituting the folding means is urged upward by the cradle 12 and supported so as to be swingable.
The folding adhesion means of the sheet 1 is constituted by a folding bar 14 made of a metal round bar processed into a substantially rectangular frame shape. The folding bar 14 is rotatably supported by the holding frame 10. The lower end side of the folding bar is provided with pressure means 21 such as its own weight or a winding spring, and is in contact with the surface of the cradle 12. As will be described later, the sheet 1 between the cradle 12 and the lower end of the folding bar is attached. Press contact with the cradle 12.

FIG. 2 is a schematic view for explaining the operation of the punching device of the simultaneous punching sheet laying device according to the present invention.
