this automatic pile up neatly anchor clamps and production line packing box diverging device (the device makes the packing box on the assembly line flow in four little runners respectively through the guide plate, the current packing box 35 of every little runner) cooperation is used, pile up neatly anchor clamps are located the diverging device end, display product packing box flows in the pile up neatly anchor clamps along with diverging device, and trigger quantity feedback switch 15 on the backplate 26, when the packing box quantity that flows in reaches and is 4, switch on signal feedback to motor controller 18, motor controller 18 control motor 4 corotation drives clamping screw 2 corotation, movable clamping piece 1 moves to the inboard through screw 3 and clamping screw 2 cooperation, make the packing box press from both sides tightly. Meanwhile, the clamping feedback switches 16 on the movable clamping pieces 4 move along with the movable clamping pieces 1, when the preset clamping interval is reached, the 4 clamping feedback switches are conducted, a conducting signal is transmitted to the motor controller 18, and the motor controller controls the motor 4 to stop rotating. The pallet clamp is moved by the trolley on the truss to which the connector 30 is attached for further stacking operations.
When the truss vehicle moves the clamp to a designated position, the clamp is integrally rotated through the rotary connector 30, and transverse placement and vertical placement can be performed. (in the stacking process, the operation of the whole stacking clamp is set in the motor controller 18, and meanwhile, the motion of the gantry truss and the motor controller 18 are in communication connection) when the direction and the position meet the preset requirements, namely after the movement and the rotation of the stacking clamp complete corresponding action instructions, the motor controller 18 receives a feedback signal, controls the motor 4 to rotate reversely for a certain time and then stops, and drives the movable clamping pieces 1 to loosen outwards through the reverse rotation of the clamping screw 2, so that the packing box is released. 4 packing boxes are placed on the tray according to the regulations, and one-time stacking operation is completed.

This automatic pile up neatly anchor clamps can once pile up neatly 4 packing boxes, has improved pile up neatly work efficiency. Pile up neatly work piles up the pile up neatly according to the route that sets for, and the pile up neatly effect is comparatively neat, is favorable to packing operation on next step. The automatic stacking clamp is simple in structure, safe, reliable, easy to use and low in cost.
The clamping screw 2 is integrally provided with four sections of threads, each of the two sections of threads on the left threaded rod 11 and the right threaded rod 14 is divided into an inner thread and an outer thread, the thread pitch of the outer thread is 2 times of that of the inner thread, the thread pitches are identical in the rotating direction, and the left threaded rod and the right threaded rod are symmetrical and opposite in the rotating direction. A screw end synchronous wheel 8 is arranged on the middle transmission rod 13 and used for transmitting the driving force of the motor 4, and the three rods are connected through a coupler 12. Through carrying out the pitch difference to four sections screw threads on the clamping screw 2, and controlling the opposite setting of spiral direction, can make the activity clamping piece 1 of installing on clamping screw 2 move in step, guarantee 4 and press from both sides the uniformity of tight interval.
As shown in the figure, when the clamping pieces are 5, the fixed clamping piece is 1, and the movable clamping piece is 4, 4 clamping feedback switches 16 capable of adjusting the limit length are designed. Each switch comprises a rubber ring 19, a base 20, a limit spacing adjusting block 21, a spring 22, an internal lead 23, a movable end 24 and a metal contact 25. The packing force is adjusted through the limit interval adjusting block 21 in the switch, different lengths of the limit interval adjusting block 21 are set according to different widths of the packing boxes, and debugging is carried out before the first start of different production batches, so that the reliability of the whole stacking process is guaranteed. Meanwhile, inside the switch, a spring 22 is further arranged on the limiting adjusting block and plays a certain buffering role so as to reduce certain distance errors caused by the problem of transmission precision of the clamping screw 2.
The clamping piece is made of aluminum alloy through sheet metal cold stamping, and the whole structure can be wavy (as shown in figure 15) so as to reduce the weight while ensuring the strength. Wherein, activity clamping piece 1 contains 4 clamping pieces, installs screw 3 again behind the welding annular piece, drives the clamp of activity clamping piece 1 and unclamps through screw 3 and the cooperation of pressing from both sides tight screw 2. The contact surface of the clamping piece and the packing box is coated with anti-slip glue to increase friction and ensure the reliability of the stacking process.
