For example, the leather shell machine performs four-station operation, the turntable 52 performs four-index intermittent rotation, then the suction nozzle groups 82 are provided with four groups, the number of suction nozzles of each group can be correspondingly set according to practical situations, when the manipulator is provided with four groups of suction nozzle groups, a plurality of groups of suction nozzle groups are equally arranged on the four positions of the turntable, the manipulator performs four-index intermittent rotation along with the turntable, and each group of suction nozzle groups sequentially moves in each station in a circulating way, so that the layout is reasonable, and the high-speed operation requirement can be met. The suction nozzle groups are respectively and correspondingly connected with first pipelines 83 for connecting air sources (such as negative pressure sources), and first valves 84 for controlling the opening and closing of the pipelines are respectively arranged on the first pipelines 83. The first valve may be a solenoid valve or a mechanical valve. The corresponding first pipeline can be controlled through the first valve 84, so that the state of the air path to the corresponding suction nozzle group is controlled. For example, when the first valve is opened at the suction station, the air source (such as negative pressure) can pass through the first pipeline to the corresponding suction nozzle group, and before the first valve is closed, the suction nozzle group is kept in an air supply state until the first valve is closed at the discharging station, the first pipeline is closed, and the air source is cut off.

The manipulator mechanism further comprises a first touching device 85 and a second touching device 86, each first pipeline 83 is connected with the rotary joint device 87 respectively, that is, each suction nozzle group is connected with the rotary joint device 87 through a corresponding first pipeline 83, when four suction nozzle groups are arranged, four first pipelines are correspondingly arranged and correspond to the four suction nozzle groups, so that each suction nozzle group is connected with the rotary joint device, and a first valve 84 is correspondingly arranged on each first pipeline 83, that is, the first valves are connected in series on the first pipeline. In this embodiment, each of the nozzle groups has a gas distribution pipe 88, which is connected to the nozzles in each of the nozzle groups by a gas pipe (not shown), and the first pipeline is connected to the gas distribution pipe, and the first pipeline is also in the form of a gas pipe. When the manipulator performs intermittent indexing rotation along with the turntable, each suction nozzle group can still be connected with the rotary joint device through the corresponding first pipeline, the rotary joint device 87 is used for connecting an air source, and the air source is connected with the rotary joint device in operation.

The first mechanical valve 84 lowered to the engagement position engages with the first touching means 85 to open the corresponding first pipe 83. The first touchdown device may be disposed at the suction station. In this embodiment, the suction station refers to a station where suction starts to descend.

The suction nozzle group rotates to the unloading station, the first mechanical valve (namely the first valve 84) corresponding to the suction nozzle group at the unloading station descends, and the descending first machinery and the second touching device 86 are matched to close the corresponding first pipeline. The first mechanical valve (i.e., the first valve 84) lowered to the mated position mates with the second touching means to close the corresponding first line. The second touching means may be arranged at the discharge station.

When the first mechanical valve is opened, the suction station keeps the opened state, and the air supply of the corresponding suction nozzle group (such as suction by a negative pressure source) is maintained until the first mechanical valve is closed along with the synchronous movement (namely lifting and rotating) of the rotary table to the descending of the discharging station, and the air supply of the corresponding suction nozzle group is stopped. When the rotary joint device is connected with the negative pressure source, the first pipeline can be controlled to be opened and closed so as to enable the suction nozzles of the corresponding suction nozzle group to suck air or not.

The suction nozzle air path control is realized by adopting a mechanical matching mode, so that the response speed is faster and more stable.

In this embodiment, the first mechanical valve adopts a toggle mechanical valve, the first mechanical valve has a toggle switch (such as a rocking handle), the toggle switch can switch on and off the first mechanical valve by toggling, the first touch device comprises a first touch block, the first touch block has a mating surface (such as a left inclined surface) mated with the toggle switch, and the second touch block has a mating surface (such as a right inclined surface) mated with the toggle switch.

In this embodiment, the first touch pad reciprocates back and forth in a lifting manner, and the reciprocating transmission device 89 uses a cylinder or a motor as a power source for transmission. When the sucking station is provided with materials, the first touch block moves forward to be matched with the first mechanical valve, and the first touch block is retracted and reset after the matching; if the suction station is empty of material, the first touchdown block will not advance and the first mechanical valve remains closed. When no material exists, the air pressure is more stable.
