[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a folding forming device for an agricultural synthetic resin sheet that is folded and formed for shipping wide and long synthetic resin sheets used for agricultural houses, tunnels, mulches and the like.

[0002]

[Prior art]

 Conventionally, folding molding of this kind of agricultural synthetic resin sheet is

(1) A long synthetic resin sheet (hereinafter, simply referred to as a sheet) cut into a predetermined length with a wide width of 5 to 15 m, which is fed out from an original fabric or by a welding machine. Two workers spread it by hand.

(2) Two workers squeeze the sheet from both sides to narrow the width of the sheet, introduce the sheet between a pair of compression rolls of an air squeezing machine, and squeeze the air between the sheets. Remove the sheet to make the sheet narrower and thinner.

(3) An operator sequentially folds the above-mentioned sheet fed out between the compression rolls into a box in a zigzag shape.

(4) An operator rests on a seat folded in the above box and stomps it with his / her feet, removes air between the seats, compresses and stores the seat in the seat.

(5) After that, the box lid is closed for packaging.

[0008]

[Problems to be solved by the device]

 In the conventional folding synthetic means for agricultural synthetic resin sheet,

(A) The sheet is squeezed from both sides and introduced into the space between the compression rolls of the air squeezing machine, the sheet fed out from between the compression rolls is folded into the box, and the folded sheet in the box is stepped on. The compression work requires 3 to 4 workers, which requires a large number of workers.

(B) Since the sheet is large and heavy, and if held, it droops and is extremely difficult to handle. Therefore, the above sheet is squeezed from both sides to be introduced between the compression rolls of the air squeezing machine, and between the compression rolls. Folding the sheet fed out from the inside of the box and folding and compressing the sheet inside the box are both labor-intensive, require a lot of physical strength, and cause a great deal of fatigue to the worker. This often causes the shoulders, waist and legs to be injured, and the worker does not last long.

[0011]

[Means for Solving the Problems]

 The present invention mechanically cuts wide and long sheets from both sides and introduces them between the compression rolls of the air squeezing machine, and folds the sheets fed out between the compression rolls to save manpower. (EN) Provided is a folding molding device for an agricultural synthetic resin sheet, which facilitates work.

That is, a horizontal receiving roll (2) is rotatably installed on the front end of the upper part of the frame (1), and guide rails (3) on both sides in the vertical direction are rotated behind the receiving roll (2). A movable base (4) which is reciprocally driven forward and backward is provided behind the both side guide rolls (3), and the regulation rolls (5) on both sides in the vertical direction are rotated at the front end of the movable base (4). A pair of compression rolls (6) and (7) in the lateral direction, which are freely rotated and are driven to rotate in the middle of the movable table (4), are closely arranged side by side to form a folding molding device for an agricultural synthetic resin sheet. Then, the sheets are squeezed from both sides and introduced between the compression rolls of the air squeezing machine, and the folding work of the sheets fed out between the compression rolls is performed mechanically to save manpower and facilitate the work. Put the sheet on the receiving roll and pass it between the guide rolls on both sides. It was realized by squeezing from both sides and passing it between the regulation rolls on both sides of a moving table that is driven to reciprocate back and forth, squeezing to a specified width from both sides, and then feeding it out with a compression roll and placing it in a zigzag shape.

When the seat (b) is stored in the box (32), the empty box (32a) is placed on the protruding portion (a) of the conveyor (a) as shown in FIG. Then, when the motor (27) is started, the conveyor (a) rotates from the rotary shaft (28) of the motor (27) through the transmission mechanism (29) and the drive shaft (26) for a certain period of time, and the empty box (32a ) Reaches the position of the box (32) and the box (32) accommodating the sheet (b) reaches the other side protruding portion (b) of the conveyor (a).

Then, the piston rod with the pressure plate (31) of the cylinder (30) is lowered by compressed air, and the sheet (b) in the box (32) is squeezed by the pressure plate (31). The air between (b) is removed and the sheet (b) is compression molded.

Thereafter, the piston rod with the pressing plate (31) is raised and restored to pack the box (32) containing the sheet (b).

Even when the sheet (b) is directly bundled without using the box (32), the sheet (b) can be folded and formed by the same operation as above.
