Description

Technical Field

[0001] The invention belongs to the field of concrete prefabricated component production equipment, and mainly relates to a steel mesh transfer line which can timely and accurately transfer steel meshes from production stations to a concrete prefabricated component production line. Background Art

[0002] Steel mesh is an indispensable embedded part in the production of precast concrete components. It is mainly used to prevent the cracking of precast concrete components. At the same time, when the precast components are installed, the steel mesh exceeds the protruding bars of the precast components and can also play a connecting role between the components. Therefore, in the production of precast concrete components, the production and transportation of embedded steel mesh are important links. The production and circulation of steel mesh are usually arranged in adjacent but different spans of the factory. The two spans of the factory are the steel mesh production line and the precast component production line respectively; at present, the steel mesh is mainly circulated on the roller conveyor in single sheets; or it is stacked and stored on pallets and transported with the pallets by forklift or hoisting. Due to the certain distance between the production equipment of the mesh and the precast component mold platform, the single sheet circulation of the mesh on the roller conveyor has the problem of low efficiency. If there are obstacles or other equipment arranged in the transmission channel, it will also bring difficulties to the setting of the roller conveyor. The mesh is stacked on the pallet and transported by forklift, which has the problem of congestion in the transportation channel and low round-trip efficiency. Not only does it occupy the channel of the production site, but there are also unsafe factors. Summary of the invention

[0003] The purpose of the present invention is to provide a steel mesh circulation line, which can conveniently and quickly circulate the steel mesh and reduce the problem of occupying production work sites.

[0004] The present invention is realized through the following technical scheme, including a pallet, a pallet conveyor line, a pallet elevator, a mesh manipulator and a pad manipulator, and is characterized in that: the pallet conveyor line is a ring-shaped conveyor line, and a pallet mesh loading station, a pallet elevator, a pallet mesh unloading station and an empty pallet elevator are sequentially arranged on the conveyor line, and each station or equipment is connected by a conveyor roller; the pallet mesh loading station is located on the first floor of the circulation line, and the pallet mesh unloading station is located on the second floor of the circulation line; the pallet is arranged on the conveyor roller, and when the pallet runs on the conveyor roller of the ring-shaped conveyor line, its chassis contacts the roller wheels of each roller in turn.

[0005] At the mesh loading station on the first floor, there are mesh robot I for hoisting the steel mesh onto the pallet and a timber robot I for hoisting the timber from the timber storage rack to the timber isolation rack and dropping it onto the steel mesh.

[0006] At the pallet unloading mesh station on the second floor, there are mesh manipulator II for lifting the steel mesh from the pallet to the mesh lifting roller and timber manipulator II for lifting the timber from the timber isolation rack to the timber storage rack.

[0007] The pallet comprises a chassis, a pad storage rack and a pad isolation rack; the pad storage rack and the pad isolation rack are vertically mounted on two opposite sides of the chassis; the pad storage rack is located at both ends of the side, and the pad isolation rack is located between the two pad storage racks on the side.

[0008] The pallet elevator and the empty pallet elevator are located at the pallet lifting opening between the first and second floors. When lowered, the rollers on the elevator are connected to the rollers of the pallet loading mesh station on the first floor, and when raised, they are connected to the rollers of the pallet unloading mesh station on the second floor; the mesh lifting roller is located at the lifting roller opening between the first and second floors, and when raised, it is located near the mesh manipulator II on the second floor, and when lowered, it is connected to the roller leading to the mold platform on the first floor; the mesh manipulator III is located near the roller leading to the mold platform.

[0009] The pallet lift has the same structure as the empty pallet lift, including a lift base, a lift scissors beam and a lift roller, the lift roller being connected to the lift base through the lift scissors beam; the four ends of the lift scissors beam are connected to the lift roller or the lift base through hinges, and the other four ends are connected to the lift roller or the lift base through lift guide rails and guide wheels; on the lift scissors beam, a pallet lifting cylinder for controlling the lifting of the lift roller is installed through the lift connecting beam; the lift roller motor is installed at the end of the lift roller.

[0010] The mesh lifting roller comprises a base, a scissors beam and a roller frame, wherein the roller frame is connected to the base via the scissors beam; the four ends of the scissors beam are connected to the roller frame or the base via hinges, and the other four ends are connected to the roller frame or the base via guide rails and guide wheels; a lifting cylinder for controlling the lifting of the roller frame is installed on the scissors beam via a connecting beam; a cylindrical roller is installed on the roller frame, and a roller motor is installed at the end of the roller frame.

[0011] The structure of the described pad manipulator I is the same as that of the pad manipulator II, including a transverse walking beam, a longitudinal walking beam, a lifting beam and a rotating frame; the rotating frame is installed under the lifting beam and driven by a rotating motor; the lifting beam is connected to the longitudinal walking beam through a slide rail seat, the longitudinal walking beam is connected to the transverse walking beam, the transverse walking beam contacts the track on the frame through the walking wheel, and is respectively connected to the lifting motor, the longitudinal motor and the transverse motor; a pneumatic opening clamp for grabbing the pads is installed under the rotating frame.

[0012] The mesh manipulators I, II and III have the same structure and are all electromagnetic chuck manipulators with three-dimensional motion.

[0013] Mesh robot I and pad robot I are located on the track of the mesh loading rack, and alternately perform reciprocating motions to lift steel mesh or pads; mesh robot II and pad robot II are located on the track of the mesh unloading rack, and alternately perform reciprocating motions to lift steel mesh or pads.

[0014] When the steel mesh transfer line is in operation, the mesh manipulator I first grabs the steel mesh made by the steel mesh welding machine and places it on the pallet at the pallet loading mesh station, and then the pad manipulator I grabs the pads on the pad storage racks on both sides of the pallet and places them above the steel mesh in the pad isolation rack, which plays an isolation role for the steel mesh placed later. The steel mesh and pads are placed in sequence. After the steel mesh in the pallet is placed, the conveyor roller is started. The pallet runs to the pallet elevator roller through the conveyor roller, and the pallet elevator rises to the second floor. The roller on the elevator is connected to the conveyor roller of the pallet mesh unloading station, and the pallet runs to the pallet mesh unloading station. At this time, the mesh manipulator II lifts the mesh on the pallet to the mesh lifting roller, and the pad manipulator II lifts the isolation pads on the mesh to the pad storage rack for storage, and lifts the mesh and pads on the pallet in sequence. The empty pallet after unloading the mesh returns to the pallet mesh loading station via the empty pallet elevator for standby use. The mesh lifting roller equipped with the mesh falls to the first layer and is transferred to the mold platform of the prefabricated component through the conveying roller and the mesh manipulator III.

[0015] The beneficial effect of the present invention is that multiple steel mesh sheets can be transported over long distances at the same time by circulating through pallets, and the circulation efficiency is high. The steel mesh sheets on the pallet are isolated by pads, and multiple layers can be stacked without hooking up. The steel mesh sheets are circulated on a two-layer platform, and the space utilization is more reasonable, so that the orderly circulation of the steel mesh sheets can be achieved. It has the characteristics of reasonable process, compact structure, high circulation efficiency and high degree of automation. It can be widely used in the automated and rapid circulation of steel mesh sheets used in various concrete prefabricated component production lines. BRIEF DESCRIPTION OF THE DRAWINGS
