BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a spreading base for an automatic spreading machine used before a cutting process in the sewing field.

[0002]

As is well known, in the field of sewing,
Prior to the cutting process, there is a spreading operation that uses an automatic spreading machine to spread and cut the original fabric to a certain length and stack it. FIG. 1 shows a spreading operation using the automatic spreading machine 1. The automatic spreading machine 1 is reciprocally moved in the arrow direction on a spreading table 2 (usually a cutting table is used), and the original After the cloth 3 is spread to a constant length, the operation of cutting with the cutter 4 is repeated to stack the original fabric on the spreading base 2. Then, the laminated product is cut by a manual cutting machine or transferred to another automatic cutting table and cut by a computer-controlled automatic cutting machine.
The spreading table used for this spreading is usually a cutting table, and the surface is flat. However, when spreading and cutting by the automatic spreading machine 1 and stacking, 3a, 3
a curls upward as shown in FIG. 2, and the stacking height is 17
The limit is -20 cm, and the fabric is not flatly stretched beyond that, making it difficult to stack. Without this problem, the automatic spreading machine has a structure that allows it to be stacked at a height higher than that, but conventionally it has been unavoidable.

[0003]

SUMMARY OF THE INVENTION In this invention, the stretched original fabric can be stacked at a height more than twice that of the conventional one.
It is an object of the present invention to provide a spreading stand for an automatic spreading machine capable of doubling the cutting efficiency.

[0004]

As a result of various trials and errors, the inventors of the present invention must have a flat cutting table for automatic spreading machine or spreading table for automatic spreading machine. We have succeeded in solving this problem by overcoming the preconceived notion of "," and creating a structure that allows both ears of the stretched and cut original fabric to hang down. That is, in the first invention, the extending portion is raised so that both ears of the original fabric hang downward. The second invention is such that the spreading portion can be moved up and down, and when the spreading portion is raised, both ears of the original fabric hang down, and when lowered, it is flat. is there. The third invention is to solve the problem of curling upward of the ear by providing a groove for hanging the ear of the original fabric. A fourth invention is such that a closing piece is detachably provided in the groove of the third invention so that a flat table is formed after the completion of spreading. A fifth invention is to improve workability by making the above-mentioned closing piece movable up and down so that it can be used as a grooved spreading table or a flat spreading table.

According to the present invention, since the cut and laminated ears of the original fabric do not hang downward and curl upward, it is possible to laminate up to about twice the height of the conventional one, which contributes to improvement in productivity.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 3 shows a first embodiment of the present invention, in which an extending portion 2 is formed so that both ears 3a of the original fabric 3 hang downward.
a is increased and the width W _{1 of the} stretched portion 2a is set to the width W of the original 3a.
_It is smaller than ₀ (W ₀ > W ₁ ). According to this embodiment, since both ears 3a hang downward and do not curl upward, it is possible to stack up to twice or more the height of the conventional case, so that the cutting efficiency can be doubled. FIG. 4 shows a second embodiment of the present invention, in which the extending portion 2b is attached to the handle 5
The cams 6 and 6 interlocking with the machine make it possible to ascend and descend, and when the automatic spreading machine 1 spreads, the spreading part 2a is raised so that both ears of the material 3 hang down, and at the time of cutting or another cutting table. In the case of moving to, the extending portion 2b is lowered to facilitate the movement. FIG. 5 shows a third embodiment, which is considered as a simple type stretcher. That is,
Depending on the width of the material, the closing pieces 7a and 7b or 7a and 7
c and remove the grooves 8a, 8b or 8 in the longitudinal direction of the original on both sides.
a and 8c are formed so that both ears of the original fabric are hung in these grooves. FIG. 6 shows a fourth embodiment, which differs from the one shown in FIG. 5 in that the closing pieces 7a, 7b, 7c are manually attached and detached, while the cams 9a, 9b are rotated by turning the handle 5. , 9c through the closing pieces 10a, 10
b is lowered to form grooves 11a, 11b for hanging the ear. The closing pieces 10a and 10
When raising and lowering c, cams 9b and 9c are fixed by screws.
You can change the fixed position of. The embodiment shown in FIG. 6 has a structure in which a closing piece having a width smaller than the thickness of the spreading table is moved up and down. However, when the width of the closing piece is larger than the thickness of the spreading table, one of the lower surfaces is It is preferable to have a structure in which the side is hinged to move up and down.

[0006]

According to the present invention, since both ears of the original fabric laminated by spreading and cutting do not curl upward unlike the conventional flat base, but hang downward rather than the conventional flat pedestal, it is laminated higher than before. Therefore, the efficiency of cutting in the next step can be significantly improved.
