Below in conjunction with accompanying drawing, the present invention is further described:

The feeding palletizer system in the present invention is a fully automatic feeding device, and the manipulator can move up and down and forward and backward. As shown in Figure 2, the initial position of the vacuum suction cup gripper 16 stays directly above the pallet, and the feeding palletizer is started , the servo motor drives the vacuum suction cup gripper 16 to descend to a certain height, and after absorbing a piece of PVC floor fabric, the servo motor drives the vacuum suction cup gripper 16 to rise to a certain height. At this time, the front and rear drive servo motors are started, and the gripper is driven forward 1m to reach directly above the feed inlet of the punch press, the vacuum suction cup is discharged, and the floor fabric enters the feed inlet of the punch press. Since the mechanical structure and working principle of the unloading palletizer are similar to those of the loading palletizer, the detailed working process is detailed in the unloading process, which will not be described here.

A piece of PVC floor fabric is punched and cut into 4 pieces by the automatic punch 2, and transported to the slot of the fixed-distance slicer 3 through the outlet of the automatic punch 2, as shown in Figures 1 and 2, when the height of the PVC floor in the slot is When higher than the fixed-distance slicing machine photoelectric switch 17, the fixed-distance slicing machine photoelectric switch 17 sends a signal to the sheet-feeding motor, and the sheet-feeding motor drives the fixed-distance synchronous pulley to send the sheet. When the PVC floor height in the draw-in groove was lower than the fixed-distance slicer photoelectric switch 17, the sheet-feeding motor stopped.

The equidistant PVC floor is delivered to the 180° turning machine 5 through the fixed-distance slicer 3, and as shown in Figures 1 and 3, the 180° turning machine 5 will realize that the odd-numbered sheets are not turned over, and the even-numbered pieces are turned over (No. 2n+1 pieces are not turned over, and the 2nth piece is turned over, where n is a natural number greater than 1), only need to explain the working principle of the first and second pieces of PVC floor turning in detail: when the turning machine is working, the photoelectric switch 4 The set value of the counter is 2, the photoelectric switch 4 senses the first PVC floor, and the count is 1. At this time, the flip arm 20 does not turn over. When the photoelectric switch 4 senses the second PVC floor, the count is 2, and the signal is sent Give the flap arm motor 21, and the flap arm motor 21 drives the flap arm 20 to rotate, realizes the turning over of the second PVC floor, and counter resets simultaneously, starts counting again. When the flap arm rotated 180 °, the flap arm proximity switch 15 sensed the flap arm, and the signal was sent to the flap arm motor 21 to make it stop running, that is, the flap arm 20 reset to prepare for the next working cycle.

The cylinder piston rod of the lifting plate is retracted, and the pneumatic lifting plate 8 is lowered. At the same time, the cylinder piston rod of the connecting plate stretches out, and the pneumatic connecting plate 7 stretches forward to catch the PVC floor that the 180 ° turning machine 5 conveys, and is positioned by the positioning baffle plate 6. When a stack of 12 PVC floors was transported through the photoelectric switch 10 under the action of the roller bed 9, the pneumatic lifting plate 8 rose, and at the same time, the pneumatic connecting plate 7 was retracted. The PVC floor is delivered to the baffle plate 12, and the photoelectric switch 11 transmits a signal to the manipulator of the unloading palletizer 13, and the manipulator of the unloading palletizer 13 starts blanking.

The specific control process of the above lifting board is as follows: the PVC floor passes through the photoelectric switch 14, and the counter counts once. When the counter reaches the preset value of 12, the normally open contact of the counter is closed, the cylinder piston is lowered, and the lowering relay coil is energized and lowered. The relay contact is closed, the pneumatic electromagnetic reversing valve is energized, and the lifting plate stops falling when it falls to the lower limit and approaches the switch.
