[Detailed description of the invention] This invention automatically knits the fully wound fabric together with the winding shaft when the knitted fabric in a knitting machine or the like is wound onto the winding shaft of the winding mechanism. Relating to the provision of a new device for taking things out of the aircraft.

In various knitting machines, such as Taiku knitting machines, the knitted fabric is guided to a winding mechanism below the knitting machine, and the winding shaft is rotated on a winding shaft that is removably mounted on the lower end of the winding mechanism. The knitting machine and the winding mechanism are stopped and the winding shaft is moved to take out the fully wound fabric from the winding shaft. It is removed from the winding mechanism, the rolled fabric and the knitted fabric connected to it are cut off, and then the rolled fabric is taken out of the knitting machine along with the winding shaft, but this is all done manually, which requires time and effort. Therefore, the knitting machine has to be stopped for a long time, which is inefficient.

The present invention aims to save labor and increase efficiency by automating the work of taking out the rolled fabric.The feature of this invention is that the winding mechanism is detachably attached to the winding mechanism. A slide table is arranged below the take-up shaft so that it can be reciprocated and stopped in the width direction of the fabric that is wound around the take-up shaft and continuous with the knitting machine, etc., and the slide table is rotatable at the upper end of the upwardly inclined surface of the slide table. A fabric cutting member that is connected to the cutter provided on the fabric cutting member, a truck body that is also provided in a direction intersecting with the slide table of the fabric cutting member so as to be able to reciprocate and stop, and a fabric cutting member that is formed on the truck body and located above the slide table. The fabric is separated from an inclined placement surface for receiving the rolled fabric located at the slanted placement surface, and a recessed bearing surface for supporting the rolled fabric formed subsequent to the inclined end of the inclined placement surface and provided with a rolled fabric sensing member. Carts for carrying out the fabric are arranged in an overlapping manner, and a control switch is provided on the movement path of the carriage for carrying out the fabric to start and stop the carriage at a fixed distance for continuous cutting of the fabric.

The present invention will be described in detail below with reference to the illustrated embodiment.

It is attached as shown in Figure H.

FIG. 4 is an explanatory diagram of the cutting and unloading operations performed by the device of the present invention, and FIG. indicates a winding shaft, and 21 indicates a presser roller.

Automatic unloading with cutting of the rolled fabric according to the present invention is carried out as follows.

In other words, the knitted fabric a that has been knitted by a knitting machine
is successively wound up on a winding shaft 20 rotatably and removably mounted on the lower ends of a pair of winding frames in a winding mechanism located below the knitting machine, through the rotation of the winding shaft 20. The rolled fabric A becomes fully rolled, and the knitting machine and winding mechanism are stopped. At this time, as shown in FIG. The circular cutter 8 is stopped below the stopped rolled material A.
A slide table 1 is stopped on one side of the rolled fabric A in the width direction.

Therefore, by unlatching both ends of the winding shaft 20 from the shaft supports at the lower end of the winding frame, the winding material A is placed on the inclined mounting surface 12a of the lower carriage main body 12 together with the winding shaft 20 which is now free. It falls due to its own weight, rolls along the slope, and is supported on the recessed support surface 12b, resulting in the state shown in FIG. 4.

In the figure, reference numeral 20a denotes a winding shaft for the next winding that is newly supplied to the shaft support of the winding frame after the winding shaft 20 is detached, and this supply may be done manually or automatically. , and 21 indicate a fabric pressing roller which is swingably provided on the winding mechanism side and is resiliently pressed against the winding shaft.

At this point, the sensing member 15 is actuated as the rolled fabric A is received onto the recessed placement surface 12b, and the trolley body 12 runs from the cut switch LSA position to the limit switch LSB position as shown in FIG. It is temporarily stopped at this position, and if the new winding shaft 20a is to be automatically supplied, it may be done at the same time as the switch LSB position of the truck body 12 is stopped.

Next, the truck body 12 travels further from the limit switch LSB position to the limit switch LSC position 1, and
While rotating the circular cutter 8 on the slide table 1, the slide table 1 is moved from the limit switch LSX position to the limit switch LSY position and stopped at the same position, so that the circular cutter 8 is moved as shown in FIG. Then, the rolled fabric A and a part of the knitted fabric A connected thereto are cut by traveling in the width direction.
As the material moves from the limit switch LSB to the LSC position 1, the material is tensioned and cut accurately and smoothly by the cutter 8, as shown in FIG.

When the cutting of the rolled fabric A and the knitted fabric A is thus completed, the slide table 1 stops at the limit switch LSY position, and the circular cutter 8 also stops.

Here, the trolley body 12 travels further from the limit switch LSC position to the limit switch LSD position and stops there, so that the wound fabric A is carried out of the knitting machine as shown in FIG. In the same figure, 2
2 is an outer frame (cover) of the knitting machine, and 23 is a hanging frame (hanging cover) that is pivotally supported on a part of the outer frame so that it can be opened and closed. I will be leaving the plane.

Note that the cut knitted fabric a is transferred to the newly supplied winding shaft 20.
The knitting machine is wound up one after another with the next operation of the knitting machine.

Next, the slide table 1 of the circular cutter 8 moves back again from the limit switch LSY position to the LSX position, and the trolley that took out the cut rolled fabric A also moves back again from the limit switch LSD position to the LSA position, and then the next unloading is carried out. will be prepared for.

As described above, the present invention makes it possible to automatically take out the rolled fabric A wound on the winding shaft of the winding mechanism out of the knitting machine, unlike the conventional manual work. This makes it possible to start operating the knitting machine immediately after unloading the rolled fabric A, thereby significantly improving the operating rate of the knitting machine without having to stop the knitting machine for a long time as in the past. is possible,
It also contributes to labor saving, and if a new take-up shaft is supplied automatically, complete automation of the knitting machine becomes possible.

In particular, in the present invention, the height of the device can be significantly lowered by combining the fabric cutting members and the fabric delivery cart, which are disposed crosswise and overlappingly below the winding shaft, and can be easily incorporated into the lower part of the knitting machine, etc. Also, after ensuring that the rolled fabric received on the inclined loading surface is supported within the recessed support surface, the main body of the cart is moved and stopped a certain distance from one switch position to the other switch position, so that the continuous fabric is Its effects are outstanding, such as being able to pull out a certain length and then stop, and while holding the fabric in a taut state, the cutter can accurately and smoothly cut the fabric by running the slide table.
