The driving plate 21 is moved to the right, thereby driving the first roller 17 to move to the right along the horizontal slide of the first slide 19, while the cross member 1 moves along the first guide rail 12. The first roller 17 moves downwards along the vertical sliding groove or the inclined sliding groove of the first sliding groove 19, the second roller 18 moves downwards along the second sliding groove, and meanwhile, the beam 1 moves downwards along the second guide rail. Referring to fig. 12, the cross member 1 is lowered to the lowest position until the driving plate 21 moves to the rightmost end. The double-groove guide mechanism is adopted in the embodiment, the horizontal and vertical movement of the cross beam can be realized only by one driving mechanism, and the cost is greatly reduced. Obviously, the double-groove guide 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 slide block structure for realizing the longitudinal movement and the vertical movement of the marking head.

The gripper of the invention can also be provided with four needle bases, the four needle bases are divided into two pairs, and the two pairs of needle bases 3 are distributed in central symmetry, namely the needle bases are distributed in four edges or four corners. The pressing block 5 is an inverted quadrangular frustum pyramid, the base 2 is provided with a groove in the shape of the inverted quadrangular frustum pyramid matched with the

pressing block

5, and 4 side surfaces of the groove are provided with needle base guide grooves. The needle seat 3 is arranged in the needle seat guide groove 2.1, and four inclined side surfaces of the pressing block 5 are respectively abutted against the top end surface of the needle seat 3. Since the needle holder 3 is disposed obliquely, the tip end surface thereof is also inclined.

The control process of the code printer is as follows:

1. remove and beat sign indicating number device to the position that needs beat the sign indicating number, place cut-parts on first platform, the part is flagging to the second platform, compresses tightly the cut-parts with the depression bar, is close to and beats pier one end and contradicts with damping device, and the both sides of cut-parts are spacing with stop device.

2. The start button is pressed.

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

4. The second driving mechanism moves towards the code printing device, drives the cut-part picking device to horizontally move to the upper side of the first platform and then moves downwards, the base of the gripper is abutted to the cut-parts until the detection device on the cross beam senses the detection block on the base, the first driving mechanism moves downwards, the needle is driven to prick into the cut-parts, and the second driving mechanism moves in the opposite direction.

5. The second driving mechanism resets and moves to the second platform top, and first driving mechanism resets, and in the needle withdrawal pinhole, cut-parts dropped to the second platform from the tongs on. The first driving mechanism can repeat the telescopic action again, so that the cut pieces can be ensured to fall off from the grip.

6. And continuing the steps 2-5 until the cut pieces can not be detected by the cut piece detection device, and stopping working.

The controller can also be provided with a counter, the number of times of code printing is counted, and whether the cut pieces on the platform have codes or not is judged according to the number of times of code printing.

What control process described above is that turn over the page to the second platform after beating the sign indicating number, also can change the coding machine a little, realize turning over the page earlier the cut-parts and pile up at the second platform, reuse cut-parts pickup apparatus to turn over the cut-parts to beat the sign indicating number on the first platform, because along with the one end of the cut-parts on the second platform is moved on the first platform, the cut-parts height on the second platform descends, the tongs need go up and down above second platform 28, consequently, the vertical spout setting of first spout is on this side of second platform.

First platform also can make the same height with the second platform, and when cut-parts pickup assembly shifted cut-parts to the second platform, moved some toward second platform department more, the cut-parts on the second platform probably piled up neatly inadequately at this time. Under the same high condition, also can turn over the page or leaf earlier with the cut-parts and pile up on the second platform, turn over the page or leaf again and beat the sign indicating number to first platform.
