For the convenience of understanding the following contents, the working flow of the flat knitting machine related to the present embodiment for automatically stacking and bundling the products a will be briefly described here:

discharging and stacking products: the manipulator 200 is installed at the blanking end of the flat knitting machine main body 100, and is used for grabbing the products a knitted by the flat knitting machine onto the discharging platform 500 one by one, and specifically placing the products a above the rotating disc 630, where the products a are stacked one by one on the rotating disc 630 and forming a product stack. In the process of stacking each product a, the batten 750 is driven by the lifting adjusting assembly to move upwards firstly, so that the product a can be smoothly discharged by the manipulator 200, then the batten 750 presses downwards and presses the product stack, and at the moment, the manipulator 200 retracts and finishes the action of smoothing the product a on the uppermost layer.

Rotation of the product stack and binding action of the rubber band b: when the number of the products a in the product stack reaches a predetermined number, the robot arm 200 stops the material grabbing motion, and the operation of the rotation assisting device 600 at this time is divided into three cases (the first driving source controls the rotation disc 630 to rotate):

1. the part of the product stack to be bundled is aligned with the conveying direction of the rubber band b: the rotating disc 630 does not rotate, the material taking and bundling device 400 grabs the rubber band b from the storage position of the sorting and feeding device 300 through the umbrella-shaped gripper, and expands, conveys and bundles the rubber band b to a product stack;

2. the part of the product stack to be bundled is not aligned with the conveying direction of the rubber band b: the rotating disc 630 rotates to enable the part of the product stack to be bundled to be aligned with the conveying direction of the rubber band b, the material taking and bundling device 400 grabs the rubber band b from the storage position of the sorting and feeding device 300 through the umbrella-shaped hand grip 440 and expands and conveys and bundles the rubber band b to the product stack, and the rotating disc 630 can rotate for multiple times to enable the material taking and bundling device to bundle the rubber band b of multiple parts of the product;

3. when the external dimension of the product stack is not suitable for the position (needing to leave a vacant position for bundling) for bundling after the material taking and bundling device 400 picks the rubber band b: the robot 200 pushes the stack of products and displaces portions of it above the outer pallet 520 where they can be sensed by the capacitive proximity switch 530 (or other type of sensor). At this time, the rotating disc 630 rotates at different angles, and the mechanical action of the mechanical arm 200 is matched, so that the product stack can move in 360 degrees in all directions, and the part of the product stack to be bundled is matched with the position of the material taking and bundling device for bundling after the rubber band b is grabbed.

Blanking of the bundled product stack: the robot 200 pushes the bundled product stack off the rotating disc 630 and is ready for the next round of product stack loading and bundling, and the bundled product stack may be dropped into a receiving frame or onto another conveyor.
