The driving plate 21 is moved rightward, thereby driving the first roller 17 to move rightward along the horizontal chute of the first chute 19, while the cross member 1 is moved along the first rail 12. The driving plate 21 continues to move right when moving to the intersection of the horizontal chute and the vertical chute of the first chute 19, at which time the intersection of the first chute 19 and the second chute 22 continues to move down, the first roller 17 moves down along the vertical chute or the inclined chute of the first chute 19, the second roller 18 moves down along the second chute, and the cross beam 1 moves down along the second rail. Referring to fig. 12, until the driving plate 21 moves to the rightmost end, the cross beam 1 is lowered to the lowest position. The embodiment adopts the double-groove guide mechanism, and only one driving mechanism is needed to realize the horizontal and vertical movement of the cross beam, thereby greatly reducing the cost. It is obvious that the double-slot guiding mechanism can also be realized by a conventional displacement mechanism, for example, the transverse movement and the vertical movement of the gripper can be realized by referring to a guide rail and a sliding block structure for realizing the longitudinal movement and the vertical movement of the wharf.

The gripper can be provided with four needle seats which are divided into two pairs, and the two pairs of needle seats 3 are distributed in a central symmetry manner, namely the needle seats are distributed in four sides or four corners. The pressing block 5 is an inverted quadrangular frustum pyramid, a groove which is matched with the pressing block 5 and is in the shape of the inverted quadrangular frustum pyramid is formed in the base 2, and needle seat guide grooves are formed in 4 side faces of the groove. The needle seat 3 is arranged in the needle seat guide groove 2.1, and four inclined side faces of the pressing block 5 are respectively propped against the top end face of the needle seat 3. Since the needle holder 3 is disposed obliquely, the tip end face thereof is also inclined.

The control process of the coding machine is as follows:

1. and moving the coding device to a position where coding is needed, placing the cut pieces on the first platform, enabling parts to droop to the second platform, pressing the cut pieces by using a pressing rod, abutting against one end of the coding head with the damping device, and limiting two sides of the cut pieces by using limiting devices.

2. The start button is pressed.

3. The third driving mechanism drives the printing head to move downwards, and the printing head resets after printing codes on the cut pieces.

4. The second driving mechanism moves towards the coding device to drive the cut piece picking device to horizontally move to the upper part of the first platform, then moves downwards, the base of the gripper abuts against the cut pieces until the detection device on the beam senses the detection block on the base, the first driving mechanism moves downwards to drive the needle to be pricked into the cut pieces, and the second driving mechanism moves in the opposite direction.

5. The second driving mechanism is reset and moved to the upper part of the second platform, the first driving mechanism is reset, the needle is retracted into the needle hole, and the cutting piece falls onto the second platform from the grip. The first driving mechanism can repeat the telescopic action again, so that the cut pieces can be ensured to fall off from the grippers.

6. And continuing the step 2-5 until the cut piece detection device cannot detect the cut piece, and stopping working.

The controller can also set a counter to count the number of times of coding, and judge whether the cutting piece is not coded or not on the platform according to the number of times of coding.

The above control process describes that the page is turned to the second platform after coding, and the coding machine can be slightly changed, so that the cut pieces are turned and stacked on the second platform, and then the cut pieces are turned to the first platform by using the cut piece picking device to code, and as one end of the cut piece on the second platform is moved to the first platform, the height of the cut piece on the second platform is lowered, and the gripper needs to lift above the second platform 28, the vertical chute of the first chute is arranged on the side of the second platform.

The first platform and the second platform may be made as tall, and the cut-parts pick-up device may move a little more to the second platform when transferring cut-parts to the second platform, but at this time the cut-parts on the second platform may not be stacked in order. Under the condition of the same height, the cut pieces can be turned and stacked on the second platform, and then the cut pieces are turned to the first platform for coding.
