Specifically, with reference to fig. 1 to 7, the feeding device of the full-automatic riveting machine for scaffold cross bars mainly comprises a frame 1 and a conveying mechanism 3 which is arranged on the frame and is used for conveying scaffold cross bars 2 (the cross bars in the feeding device are to-be-processed pieces, and inserting pieces are not inserted), wherein:
The relative distance between the two sides of the frame 1 is adjustable so as to adjust the width of the frame according to the length of the cross bars 2 to meet the requirement of the transmission of the cross bars 2 with different lengths, and the width adjustment of the frame is the conventional technology, and the frame is not unfolded any more.
The conveying mechanism 3 comprises a front conveying mechanism 31, a rear conveying mechanism 32 and a pushing mechanism 33 arranged between the front conveying mechanism and the rear conveying mechanism, wherein the front conveying mechanism 31 is arranged at the feeding end of the frame 1 and mainly comprises a conveying belt and two limiting plates 311, and the conveying belt can adopt a conventional closed-loop conveying belt (not shown in the figure) and can be driven by adopting the prior art. The cross bar 2 is conveyed from the feed end into a predetermined slot 312 below the stop plate 311 by a conveyor belt. The two limiting plates 311 are correspondingly arranged on two sides of the frame 1 and correspond to the pushing mechanism 33 below the frame, and the cross rod 2 can smoothly roll into a preset groove 312 below the limiting plates 311 through the limiting plates 311 so as to flush and orderly convey the cross rod 2 to the pushing mechanism 33, thereby avoiding superposition and dislocation.
The pushing mechanism 33 is a rotary pushing mechanism, and mainly comprises a fixing frame 331, a rotating plate 332, a driving member 333, an inductor, and the like, wherein the fixing frame 331, the rotating plate 332, the driving member 333, and the inductor are all two, and are arranged on two sides of the frame 1 in a one-to-one correspondence manner. As shown in fig. 3, the fixing frame 331 is fixed on the inner sidewall of the frame 1 and is located below the limiting plate 311. The top of the fixing frame 331 is provided with a predetermined groove 312, the predetermined groove 312 is matched with the outer circumferential shape of the main body of the cross rod 2, and a connecting part 334 which is arranged obliquely downwards is further arranged at one side of the predetermined groove 312 close to the rear-stage conveying mechanism 32, and the connecting part 334 is used for smoothly feeding the cross rod 2 pushed by the rotating plate 332 onto the conveying chain 331 at the rear stage.
The rotating plate 332 has an eccentric wheel-like structure, and is connected to the fixing frame 331 to rotate around the shaft. The rotating plate 332 is formed with a blocking portion 332a on its outer circumference for pushing the cross bar, in the non-rotated state of the rotating plate 332, the blocking portion 332a is opened upward to face the cross bar 2 located above and limited in the predetermined slot 312, and when the rotating plate 332 is rotated (counterclockwise rotated), the blocking portion 332a is rotated upward to contact with the cross bar 2, so that the blocking portion 332a pushes the cross bar 2 to leave the predetermined slot 312 and pushes the cross bar 2 out, and one cross bar 2 can be pushed every time the rotating plate 332 rotates.

An inductor (not shown) is mounted on the fixing frame 331 below the predetermined slot 312, and the inductor may be an infrared transceiver sensor for sensing whether the transverse rod 2 to be pushed is placed in the predetermined slot 312. When the cross bar 2 is placed in the predetermined slot 312, the infrared rays emitted by the sensor are blocked and reflected, so that the reflected infrared rays can be received to judge that the cross bar 2 is placed in the predetermined slot 312, otherwise, the cross bar 2 is not placed in the predetermined slot 312. In a state that both side sensors sense that the predetermined groove 312 is provided with the cross bar 2, the control device automatically starts the two cylinders to operate, so that the two rotating plates 332 are driven to synchronously rotate, the cross bar 2 is pushed to fall to the connecting part 334, and then rolls into the conveying chain 32 at the rear stage through the connecting part 334.

Preferably, the feeding device can be matched with the subsequent station of the riveting machine to carry out the transmission of the cross rod 2, and two sides of the rack at the output end can be respectively provided with an inductor so as to control the action of the conveying chain 321. In order to enable the cross bars 2 to be conveyed one by one at certain intervals, a plurality of positioning plates 322 which are arranged at intervals are uniformly distributed on the whole conveying chain 321, and the lock heads 21 on the cross bars 2 fall between two adjacent positioning plates 322. The positioning plate 322 has a substantially L-shape and has a second horizontal portion 322a and an upright portion 322b bent upward from the second horizontal portion 322a, and the second horizontal portion 322a has a mounting hole for fixing the second horizontal portion and the conveying chain 321 by a fastener. Of course, the positioning plate 332 may be fixed with the conveying chain in other manners, which is not limited thereto.
The guide plate 323 is fixed on the inner side wall of the frame 1, and is provided with a corresponding oblique part 323a which is obliquely arranged upwards and a first horizontal part 323b which horizontally extends, corresponding to the travelling direction of the conveying chain 321, so that the locking heads 21 at two ends of the cross rod 2 can move upwards along the guide plate 323 and contact with each other in the travelling process, and the angles of the locking heads 21 are adjusted, so that the cross rod can be output in a horizontal state.
The feeding device further comprises a control device, and the driving piece, the sensor and the driving device for driving the conveyor belt and the conveying chain to rotate are electrically connected with the control device so as to control the driving devices and the driving piece to act according to signals of the sensor.
The working principle of the feeding device is as follows:
The cross bar 2 is first conveyed into the predetermined slot 312 by the conveyor belt, and when the sensors on both sides of the frame 1 sense that the cross bar 2 is in the predetermined slot 312, the driving member (cylinder) 333 acts to drive the rotating plate 332 to rotate counterclockwise, and the rotating plate 332 pushes the cross bar 2, so that the cross bar 2 enters the conveying chain 321 of the subsequent stage. Wherein, every time the rotating plate 332 rotates one circle, a cross rod is pushed to perform a circulating action. The pushed cross bars 2 are conveyed to the output end of the feeding device one by the conveying chain 321. And in the process of conveying and moving upwards, the angles of the lock heads on the transverse rods are continuously adjusted due to the action of the guide plates, so that the lock heads on the transverse rods are adjusted to be in the same horizontal state when the transverse rods reach the output end.
