This elbow automatic feeding device material lifting mechanism 1 is including promoting hopper 11, striker cylinder 17 and striker plate 18. A vertical lifting slide way 13 is arranged at the front end of one vertical side face of the rack 6, a lifting slide block 14 is connected onto the lifting slide way 13, and a lifting hopper 11 is fixedly connected onto the lifting slide block 14, so that the lifting hopper 11 is vertically and slidably connected to the front end of the vertical side face of the rack 6; the lower end of the lifting hopper 11 is connected with the output end of the lifting cylinder 12, so that the lifting cylinder 12 can drive the lifting hopper 11 to slide up and down. The lifting hopper 11 is of a hopper-shaped structure, the feed opening is over against the frame 6, and the bottom surface of the lifting hopper 11 is obliquely and downwards inclined towards the feed opening; like this, the elbow in the promotion hopper 11 can be at the position of gravity gliding to the feed opening to because the frame 6 can keep off the feed opening, can prevent to promote the elbow in the hopper 11 and drop at the promotion in-process. When the lifting hopper 11 rises to the highest point, the lower edge of the discharge port of the lifting hopper 11 is flush with the upper end of the frame 6. The feeding mechanism 7 comprises a feeding track 72 and a vibrating feeder 71, wherein the feeding track 72 is arranged on the other vertical side surface of the frame 6. A sliding material baffle plate 19 is arranged on the machine frame at the upper part of the feeding track 72; the sliding material baffle plate 19 is obliquely arranged, the upper end of the sliding material baffle plate 19 is over against the upper end of the rack 6, and the lower end of the sliding material baffle plate 19 is over against the feeding track 72. The material sliding baffle 19 includes a base plate disposed obliquely, and baffles disposed at the front and rear sides of the base plate to prevent the elbows 4 from falling off from both sides. After the structure is adopted, when the lifting hopper 11 rises to the highest point, the inclined bottom surface of the lifting hopper 11 and the inclined bottom plate of the sliding material baffle plate 19 form a slide way inclined towards the feeding track 72, and the elbow 4 can slide downwards under the action of gravity and fall to the feeding track 72 along the slide way. If a gap exists between the lifting hopper 11 and the sliding material baffle plate 19, a barrier strip 110 can be arranged above the rack 6; the barrier strips 110 are positioned between the gaps and are obliquely arranged, the upper ends of the barrier strips correspond to the lower ends of the feed openings after the lifting hopper 11 is lifted, and the lower ends of the barrier strips correspond to the upper parts of the sliding material baffles 19; the bars 110 are thus engaged between the elevator hopper 11 and the slip sheet skirt 19.

After the structure is adopted, the screening push sheet 111 only allows the elbows 4 in the horizontal posture to fall into the feeding track, the unqualified postures and the accumulated elbows 4 are blocked by the screening push sheet 111, and the unqualified postures and the accumulated elbows can be pushed back into the lifting hopper 11 under the pushing of the screening air cylinder 16.
In the feeding mechanism 7 of the elbow automatic feeding device, a feeding track 72 horizontally extends from the front end of the rack 6 to the rear end of the rack; the vibrating feeder 71 is positioned below the feeding track 72; thus, the feeding rail 72 can feed the bent pipe to the rear end of the feeding rail 72 by the vibrating feeder 71. The feeding rail 72 is in a long groove strip structure, and the groove width is matched with the pipe diameter of the elbow 4; in this way, the bends 4 can only be transported in the feed track 72 in a position in which the nozzle is directed upwards or downwards. The tail end of the feeding track 72 is provided with an attitude sensor, and the attitude sensor is preferably a photoelectric switch; when the pipe orifice of the elbow at the tail end of the feeding track 72 faces upwards, the attitude sensor is over against the pipe body at the middle lower part of the elbow; when the pipe orifice of the elbow at the tail end of the feeding track 72 faces downwards, the attitude sensor faces the space of the inner bend of the elbow, namely does not face the pipe body; therefore, whether the elbow is in an upward or downward posture can be judged according to the triggering condition of the posture sensor.
This elbow automatic feeding device elevating system 8 is including location tray 89 and ejector pad mechanism. The positioning support block 89 is positioned at the conveying rear end of the feeding track 72, the positioning support block 89 is provided with a support groove on the upper part of a square block body, and the support groove penetrates through the block body in a direction vertical to the conveying direction of the feeding track; along the conveying direction of the feeding track, the front end surface 811 of the bracket inclines backwards and downwards, the rear end surface 812 inclines forwards and downwards, and the distance between the front end surface and the rear end surface of the top of the bracket is greater than the closest distance between two pipe orifices of the elbow, so that an ︺ -shaped structure is formed; because the elbow on the feeding track 7 is in the posture that the pipe orifice is upward or downward, the elbows 4 in the two postures enter the positioning supporting block 89, and can fall into the bracket and be supported by the bracket. A downward vertical groove 810 is formed in the middle of the upper part of the block body at the front end and the rear end of the bracket along the conveying direction of the feeding track; because the elbow 4 is a round tube and is provided with the vertical groove 810, a part of the outer diameter of the contact part of the elbow 4 and the vertical groove 810 can fall into the vertical groove 810, thereby improving the stability of the elbow 4 in the bracket. One end of the lower portion of the positioning support block 89, which is close to the feeding rail 72, is provided with a vertical anti-falling baffle 83, and the anti-falling baffle 73 can be pushed up at the rear conveying end of the feeding rail 72 to prevent an elbow at the rear conveying end of the feeding rail 72 from falling.
The push block mechanism of the automatic elbow feeding device comprises a push block guide rail 81, a push block supporting plate 84 and a power mechanism. The push block guide rail 81 is vertically arranged on the frame 6 below the positioning supporting block 89. The power mechanism comprises a synchronous motor 87, a synchronous belt wheel 82, a synchronous belt 86 and a synchronous guide plate 85; the synchronous motor 87 is fixedly connected to the frame 6, and the synchronous belt wheel 82 is rotatably connected to the frame below the synchronous motor 87 through a connecting shaft; the synchronous motor 87 and the synchronous pulley 82 are in transmission connection through a synchronous belt 86. The synchronous guide plate 85 is fixedly connected to the synchronous belt 86 and is slidably connected to the push block guide rail 81 through the push block sliding block 88. The push block supporting plate 84 is vertically arranged, the upper end of the push block supporting plate is fixedly connected with the lower end of the positioning supporting block 89, and the lower end of the push block supporting plate is fixedly connected with the synchronous guide plate 85. Thus, when the synchronous motor 87 rotates, the synchronous belt 86 is driven to rotate between the synchronous motor and the synchronous belt wheel, and the synchronous guide plate 85 fixedly connected with the synchronous belt 86 can move up and down under the driving of the synchronous belt and slide up and down on the push block guide rail 81; the synchronous guide plate 85 moving up and down drives the push block supporting plate 84 to move up or down; the pushing block supporting plate 84 moving up or down drives the positioning supporting block 89 to move up and down, so as to drive the elbow 4 on the positioning supporting block 89 to move up and down.
The elbow automatic feeding device comprises a rotating cylinder 32 and a finger cylinder 31. The rotary cylinder 32 is fixedly connected to the upper part of the rack at the rear end of the positioning support block 89, and the output end of the rotary cylinder 32 extends towards the direction of the positioning support block 89 and is connected with the finger cylinder 31; after the positioning support block 89 is lifted, the supported elbow is positioned between the clamping fingers 33 of the finger cylinder 31; after the positioning support block 89 descends, the upper end of the positioning support block is flush with the bottom of the feeding rail 72; thus, the positioning support block 89 can receive the elbow conveyed by the feeding track 72 and support the elbow upwards between the clamping fingers 33 of the finger cylinder, so that the finger cylinder 31 can clamp the elbow conveniently.
The material pushing structure of the automatic elbow feeding device comprises a material pushing cylinder 21 and a push plate 22. The material pushing cylinder 21 is fixedly arranged at the upper part of the rack, and the output end of the material pushing cylinder extends out towards the direction of the piece entering slide way 5; the push plate 22 is fixedly connected with the output end of the material pushing cylinder 21; the push plate 22 and the workpiece inlet slide way 5 are oppositely arranged and are respectively arranged at two sides of the positioning support block 89; the push plate 22 and the workpiece inlet slide 5 are lower than the clamping fingers 33 of the finger cylinder and higher than or flush with the feeding track 72. Thus, the pushing cylinder 21 can drive the pushing plate 22 to push the elbow 4 on the positioning support block out towards the workpiece feeding slide way 5 of the processing device, so that the elbow is pushed onto the workpiece feeding slide way 5, and feeding of the processing device is achieved.
The method for automatically feeding the elbow comprises the following steps: (1) the lifting hopper 11 is lowered to the lower part of the frame to receive the feed of the previous process.
(2) Driven by a lifting cylinder 12, the lifting hopper 11 moves upwards on the rack and drives an elbow therein to move upwards; until the inclined bottom end of the lifting hopper 11 is flush with the upper end of the frame; at this time, since the bottom surface of the lifting hopper 11 is designed to be inclined, the elbow will slide down to the position of the frame and be blocked by the striker plate 18 and stacked together.
(3) The material blocking cylinder 17 drives the material blocking plate 18 to rise upwards, and a channel capable of accommodating an elbow is formed below the material blocking plate 17; so that part of the elbow will pass through the channel and enter the sliding material baffle plate 19, and slide down to the conveying front end of the feeding track 72 along the sliding material baffle plate 19; due to the limitation of the groove width of the feeding rail 72 and the posture adjustment in the sliding process, the elbow 4 on the feeding rail 72 can only fall into the feeding rail in the posture that the pipe orifice is upward or downward. The material blocking cylinder 17 is controlled to drive the material blocking plate 18 to rise or fall, and the feeding speed to the feeding track 72 can be controlled; when the feeding rail 72 falls into the elbow, feeding is stopped. In the process that the elbow 4 slides down the sliding material baffle plate 19, the screening push sheet 111 pushes the unqualified and accumulated elbow 4 back into the lifting hopper 11 under the pushing of the screening air cylinder 16.
(4) The elbow 4 on the feeding track 72 is fed to the rear end of the conveying under the action of the vibrating feeder 71; the attitude sensor determines whether the elbow 4 is in the attitude of spout-down or spout-up.
(5) The elbow 4 at the conveying tail end on the feeding track 72 enters the positioning supporting block 89 and is supported by the positioning supporting block 89; the vibration feeder 71 stops working, and the feeding rail 72 stops feeding; the synchronous motor 87 rotates, and the synchronous belt 86 drives the positioning support block 89 and the elbow to move upwards. And (4) judging the elbow attitude according to the attitude sensor in the step (4), and performing the following step (6) or (7).
(6) When the elbow gesture does not conform to processingequipment's material loading gesture: the synchronous motor 87 drives the elbow on the positioning support block 89 to rise to the finger position of the finger clamp 33 of the finger cylinder; the clamping fingers 33 of the finger cylinder clamp the elbows on the positioning support blocks 89; after the elbow is clamped by the finger cylinder 31, the elbow is rotated by 180 degrees by the rotating cylinder 32, so that the elbow is rotated to a posture according with the feeding posture; then the synchronous motor 87 drives the elbow on the positioning support block 89 to descend to the position of the piece entering slideway 5.
