Field of the Invention The present invention relates to a fabric transfer in which a fully wound fabric knitted by a circular knitting machine is removed from a winding shaft, transferred to a fabric receiving table, and transported to the next processing step. Related to the device.

[0002]

2. Description of the Related Art Conventionally, a dough winding device for winding and removing a full-wound dough knitted by a circular knitting machine of this kind on a winding shaft is constructed as shown in FIGS. (Japanese Patent Publication No. 1-59372, Japanese Patent Publication No. 2-6862)
issue).

That is, in FIGS. 12 to 16, a plurality (3 in FIG.
Each of the legs a of the book) is provided with a columnar support b vertically via a disk-shaped machine base f. A knitting machine cylinder c is rotated inside the support b. It is fitted freely. Each knitting needle is provided in a large number of vertical grooves of the knitting machine cylinder c so as to slide in the vertical direction by a cam mechanism or the like (not shown). It is provided so as to slide in the radial direction in conjunction with the operation of each knitting needle. Further, a dial mechanism d is mounted on the support b directly above the knitting machine cylinder c so as to rotate in synchronization with the knitting machine cylinder c. A yarn feeding device e is provided.

On the other hand, a pair of supporting rods g is provided to be suspended from a machine base f above the leg a, and three squeezing rollers h are knitted at the base of the supporting rods g. The shaft is mounted horizontally and rotatably so as to squeeze it flat, also serving as a guide for the fabric W. Further, at the lower part of the pair of supporting rods g, the two divided winding shafts i are axially slidably and rotatably mounted so as to be anastomosed with each other.
Each flange j formed at each outer end of each
The locking rods k are configured to move in the axial direction by rotation of a link mechanism and a feed screw rod (not shown). Further, in the middle of each winding shaft i, each gear m is connected to a ratchet mechanism o via each transmission gear n meshing with it, and each gear m is integrated with each rotation shaft of each transmission gear n. Each other sprocket q is connected to the sprocket p via each belt r. Further, a cloth holding member t is axially mounted on the rotation shaft s of each sprocket q so as to press the cloth W with the elasticity of the spring u. In addition, as shown in FIG. 16, the fully-wound fabric W detached from each of the winding shafts i is dropped onto a receiving cart v provided with casters. Then, the full-length cloth W is cut by a pair of circular circular cutters w.

[0005] Therefore, the above-described cloth take-up device uses the cloth W knitted by the operation of the knitting machine cylinder c and sinker.
Is squeezed downward by each of the squeezing rollers h, and is sent downward. An end of the hung cloth W is anastomosed and sandwiched by each end of each of the two divided winding shafts i. By driving o, each winding shaft i is intermittently rotated via each gear n and m to wind up the cloth W. When the cloth W reaches a predetermined size, each flange of each winding shaft i is rotated. By engaging each locking rod k with j and moving in the axial direction outward from each other and pulling out each winding shaft i from the full-width cloth W, the full-roll cloth W is placed on the receiving cart v. Then, as shown in FIG. 16, the full-length cloth W is cut by a pair of circular circular cutters w.

[0006]

However, in the above-described cloth winding device, when the cloth W has a predetermined size, the locking rods k are engaged with the flanges j of the winding shafts i so that the locking rods k are separated from each other. By moving in the other axial direction and pulling out each winding shaft i from the fully-wound fabric W, the fully-wound fabric W is dropped and placed on the receiving trolley v, as shown in FIG. Since the full-width dough W is cut by a pair of circular circular cutters w, due to the weight of the full-roll dough W,
Each winding shaft i is bent over time, which makes it difficult for the ends of the winding shafts i to anastomose each other at a normal position, and also causes the full-battered cloth W to fall on the receiving cart v. As a result, the fabric is impacted, and the quality of the fabric may be impaired.

[0007] The present invention has been made in view of the above circumstances, and silently placing a full-battered cloth on a receiving table,
It is an object of the present invention to provide a dough transfer device in which a dough is not damaged by a pulling force applied to a dough edge when a full roll of dough is conveyed outward and taken out.

[0008]

According to the present invention, in a circular knitting machine provided with a dough winding device for winding a dough knitted by a knitting machine cylinder on a winding shaft, the dough conveying device is provided directly below the knitting machine cylinder. A feed screw rod horizontally mounted on the machine base, a slider member screwed on the feed screw rod, a lifter device provided on the slider member so as to be able to move up and down, and a cloth provided on the lifter device It is characterized by comprising a receiving table, a receiving tray placed on the dough receiving table via a buffer spring, and a dough receiving roller provided on the receiving tray.

[0009]

In the dough conveying device of the present invention, when removing the full dough, the lifter device is lifted and the tray placed on the dough receiving table via the buffer spring is brought into contact with the full dough to remove the dough. When the full weight of the dough is transferred and the take-up shaft is pulled out and the full dough is supported on the receiving tray, the full dough is quietly placed on the receiving tray without giving an impact by the action of the buffer spring,
A pulling force acting tangentially to the take-up shaft at the end of the fully-loaded dough was provided to the tray when the fully-loaded dough supported by the dough support was transported outward and taken out. By rotating the cloth receiving roller, the pulling force is reduced so that the cloth is not damaged.
