Detailed Description

As shown in fig. 1, the double-feeding type automatic feeding machine comprises a rack 5, and a discharging unit 1, a sorting unit 2, a feeding unit 3 and a control circuit unit which are mounted on the rack. The sequencing unit 2 and the feeding unit 3 have two sets; the blanking unit 1 is respectively and correspondingly provided with a set of sequencing unit 2 towards two sides, and each set of sequencing unit 2 is correspondingly provided with a set of feeding unit 3. The blanking unit 1 is used for feeding materials to the feeding machine, the sorting unit 2 is used for sorting and conveying external threads, the feeding unit 3 is used for feeding the external threads into the tapping machine, and the control unit is used for controlling the operation of the units.

As shown in fig. 1 and 8, the blanking unit 1 of the double-feeding type automatic feeder comprises a blanking hopper 12, an adjusting door 13 and a push rod 16. A blanking barrel 11 is arranged above the blanking hopper 12, the blanking barrel 11 is cylindrical, the upper end of the blanking barrel is communicated with the previous processing unit, and the blanking barrel is used for conveying the outer wires processed by the previous processing unit to the blanking hopper 12. The lower hopper 12 is cylindrical, an adjusting door 13 is arranged below the side part, and the adjusting door 13 can be adjusted up and down to open or close the adjusting door. The bottom of the blanking hopper 12 is provided with a nesting-preventing bottom 14, and the nesting-preventing bottom 14 is an inclined plane; the inclined plane is opposite to the adjusting door 13, and the bottom of the inclined plane is equal to or slightly higher than the bottom of the adjusting door; therefore, after the outer wires enter the discharging hopper 12, the outer wires can directly slide towards the direction of the adjusting door 13 along the anti-nesting bottom 14, and the accumulation of the outer wires at the bottom of the discharging hopper 12 is avoided. A push rod 16 is arranged in the lower hopper 12 at a position opposite to the adjusting door 13, and one end of the push rod 16 far away from the adjusting door is connected with a discharging cylinder 15; the blanking air cylinder 15 can drive the push rod 16 to move towards the adjusting door 13, so that the outer wire is pushed out of the adjusting door 13. After adopting above-mentioned structure, the unloading process is: the external thread enters a discharging hopper 12 through a discharging barrel 11, and slides to an adjusting door along an obliquely-arranged anti-nesting bottom 14 at the bottom of the discharging hopper 12; the push rod 16 is driven by the blanking cylinder 15 to push the outer wire to move towards the direction of the adjusting door 13; the outer wire falls from the adjusting door 13 to the starting end of the sequencing unit; the push rod 16 is retracted and then pushes the outer wire again to fall out of the adjustment gate 13.

As shown in fig. 1, 2 and 3, the sorting units 2 of the double-loading automatic feeder each include a sorting rail 24, a material combing mechanism, a linear vibration feeder 25, a lifting mechanism, a remote pushing mechanism and a remote pushing rail 23. The following is written by taking one of the sorting units as an example. The sorting track 24 is arranged corresponding to the adjusting door 13 of the blanking unit, and the outer wire 6 dropped from the adjusting door 13 falls to the starting end of the sorting track 24. The sorting track 24 is a strip track, and the bottom surface is preferably of a V-shaped or U-shaped structure, so that the outer wire has a posture changed from a transverse posture to a posture along the sorting track, and the trend that the outer wire is changed from the posture along the sorting track to the transverse posture can be effectively prevented; a material baffle plate 21 is arranged at the corresponding position of the sequencing track 24 and the adjusting door 13 and is used for preventing the outer wires from falling off from the sequencing track 24 in the blanking process. A linear vibration feeder 25 is installed below the start end of the sorting rail 24 to feed the outer wire 6 to the end. The material combing mechanism comprises a material combing plate and a bidirectional cylinder 22; as shown in fig. 9, the material combing plate is located above the front middle part of the sorting track and comprises a rear material combing rubber plate 27 and a front material combing rubber plate 26 which are fixedly connected together; the rear combing rubber plate 27 is of a double-door-column structure, and the front combing rubber plate 26 is of a single-door-column structure; the combing holes formed by the combination are matched with the sequencing track 24, only the outer wires which have the required postures and are along the direction of the sequencing track are allowed to enter and pass, and the outer wires which do not meet the form requirements are blocked. The combing plate is connected with a cylinder rod of the bidirectional cylinder 22 at the end of the conveying direction, so that the cylinder rod can push the outer wires to the direction opposite to the conveying direction, and the blocked outer wires which do not meet the form requirement are pushed back to the starting end of the sequencing track. As shown in fig. 1, 4 and 5, the tail end of the sequencing track 24 is provided with a lifting mechanism; the lifting mechanism comprises a lifting track 214 and a lifting cylinder, the lifting track 214 is connected with the lifting cylinder through a lifting connecting plate 213, and the lifting cylinder is used for pushing the lifting track to lift; the front end of the lifting track 214 after falling is connected with the sorting track 24, so that the outer wires conveyed by the sorting track can be connected; the side of the lifting rail 214 is provided with a side anti-falling plate 212, and the upper surface is provided with an upper anti-falling plate 28, so as to prevent the outer wires from falling off from the lifting rail. The raised rear end of the lifting rail 214 is in contact with the pushing rail 23. The far-push rail 23 is a strip-shaped rail, a side far-push baffle 211 is arranged on the side surface of the far-push rail, and an upper far-push baffle 29 is arranged on the side surface of the far-push rail, so that the posture of the outer wire in the sliding process can be prevented from being changed, and the outer wire can be prevented from falling off from the far-push rail. The remote pushing mechanism comprises a remote pushing block 210, the remote pushing block 210 is positioned above the front part of the remote pushing track and is connected with another cylinder rod of the bidirectional cylinder 22, and the pushing direction of the cylinder rod is the same as the conveying direction of the outer wire; after the lifting rail 214 is lifted, the bidirectional air cylinder 22 can push the outer wire on the lifting rail into the far-pushing rail. The conveying process comprises the following steps: the outer wire 6 falls to the starting end of the sequencing track 24 from the adjusting door 13 of the discharging hopper; the striker plate 21 cannot fall to the ground due to its blocking. The outer wire is conveyed in both right and left directions along the two sorting rails 24 by the vibration of the linear vibration feeder 25. Because the sorting track 24 is a V-shaped or U-shaped strip track, the posture of the outer wire can be continuously adjusted in the transportation process so as to meet the requirements; after encountering the material combing mechanism, the external wires which do not meet the form requirement cannot enter a material combing hole formed by the combination of the back material combing rubber plate 27 and the front material combing rubber plate 26, and are pushed back to the starting end of the sequencing track 24 by the material combing plate driven by the bidirectional cylinder 22; and the outer wire with the required posture is continuously conveyed on the sequencing track 24 through the carding holes. And because the sorting track 24 is V-shaped or U-shaped, the posture of the outer wire is not changed in the transportation process, thereby realizing automatic sorting and posture adjustment. The external thread is sent into the lifting track 214 from the sequencing track 24, and the lifting track 214 is driven by the lifting cylinder to move upwards and is connected with the far pushing track 23; the bidirectional cylinder 22 drives the far-push block 210 to push the outer wire on the lifting rail towards the conveying direction, and the outer wire slides to the far-push rail 23 under the action of the pushing force and slides to the tail end of the far-push rail along the far-push rail.

As shown in fig. 1, 6 and 7, the feeding unit 3 of the double-feeding type automatic feeding machine includes a pushing mechanism and a pushing cylinder, and the pushing mechanism is disposed at the end of the far-pushing rail 23. The material pushing mechanism comprises a material pushing block 32 and a material pushing bracket 31; the pusher blocks 32 are arranged on both sides of the pusher rail 23 opposite to the feed end of the tapping machine scraper-trough conveyor 4. The material pushing block 32 is fixedly connected with the material pushing support 31, and the material pushing support 31 is connected with a material pushing cylinder; the pushing cylinder is used for pushing the pushing block 32 towards the direction of the feeding end of the tapping machine scraper-trough conveyer 4, so that the pushing block 32 pushes the outer wire 6 on the far pushing rail 23 into the feeding end of the tapping machine scraper-trough conveyer 4. The side face of the pushing mechanism is provided with a side pushing baffle 33, and the upper face of the pushing mechanism is provided with an upper pushing baffle 34, so that the outer silk is prevented from falling off in the pushing process. The feeding process comprises the following steps: the outer wires 6 sliding to the tail end of the far pushing track 23 are vertically pushed to the inlet of the tapping machine scraper-trough conveyer 4 by a material pushing block 32 driven by a material pushing support 31 and a material pushing cylinder, so that the tapping machine scraper-trough conveyer is fed.

This automatic material loading machine of two material loading formula control circuit unit includes control chip (PLC), correlation photoelectric switch, target in place sensor and full sensor of material. The signal input end of the control chip PLC is connected with the correlation photoelectric switch, the in-place sensor and the full-material sensor, and the signal output end of the control chip PLC is connected with the blanking cylinder 15, the bidirectional cylinder 22, the lifting cylinder and the material pushing cylinder. The emitter of the correlation photoelectric switch is arranged on one side of the starting end of the sequencing track 24, and the receiver is arranged on the other side of the sequencing track 24 in a matching way. The correlation photoelectric switch detects whether the starting end of the sequencing unit has an external thread. If the photoelectric switch does not detect the external thread, the control chip PLC drives the blanking cylinder 15, and the push rod 16 is driven by the blanking cylinder 15 to push the external thread in the blanking hopper 12, so that the external thread falls from the blanking hopper 12 to the starting end of the sequencing track 24. The in-position sensor is mounted at the end of the push-away rail 23 and functions to determine whether the outer wire reaches the reach of the pusher mechanism. The full material sensor is arranged on the tapping machine scraper-trough conveyer 4 and is used for determining whether an external thread exists on the tapping machine scraper-trough conveyer 4. The blanking cylinder 15 is responsible for controlling whether the push rod 16 pushes materials or not. The bidirectional cylinder 22 is responsible for controlling whether the material combing plate carries out material combing operation or not and controlling whether the far pushing block 210 pushes materials or not. The lifting cylinder is used to take charge of lifting or lowering the lifting rail 214. The pushing cylinder is responsible for controlling whether the pushing block 32 pushes the outer wire from the tail end of the sequencing unit to the scraper-trough conveyer 4. The control circuit unit works as follows: when the correlation photoelectric switch cannot detect that the outer wire is arranged at the starting end of the sequencing unit, the control chip PLC controls the blanking cylinder to work, and the blanking cylinder drives the push rod to carry out blanking operation; when the in-place sensor detects the outer wire and the full-material sensor does not detect the outer wire, the control chip PLC controls the material pushing cylinder to drive the material pushing mechanism to perform material pushing operation; the bidirectional air cylinder periodically pushes the material to be combed in the material conveying process of the linear vibration feeder; when the in-place sensor cannot detect the outer wire and the piece lifting mechanism is in the lifting position, the material pushing operation is carried out, and the outer wire is pushed to the position of the in-place sensor to finish the far pushing of the outer wire.

This two material loading formula automatic feeding machine's use does: (1) the outer wire 6 enters the discharge hopper 12 through the discharge bucket 11, and slides in the discharge hopper 12 along the anti-nesting bottom 14 to the adjusting door 13. The correlation photoelectric switch arranged at the starting end of the sequencing track 24 does not detect the outer wire, the control chip PLC controls the blanking cylinder 15 to drive the push rod 16 to move, the outer wire is pushed to move towards the direction of the adjusting door 13, and the outer wire falls to the starting end of the sequencing track 24. Subsequently, the push rod 16 is retracted and the pushing action is performed again.

(2) The outer wire drops to the initiating terminal of sequencing track 24 from the regulation door of hopper under stopping of striker plate 21. The outer wire is carried along the sorting rail 24 under the vibration of the linear vibration feeder 25. The outer silk can constantly adjust the gesture in transportation in order to meet the demands to after meetting the comb flitch, the outer silk that does not conform to the form demand can not get into the comb material hole that the combination of back comb material offset plate 27 and preceding comb material offset plate 26 formed, and the comb flitch propelling movement that is driven under the comb material cylinder gets back to the orbital initiating terminal of sequencing. And the outer wire with the posture meeting the requirement continuously moves on the sequencing track through the carding hole.

(3) The external thread enters the lifting track 214 from the tail end of the sequencing track 24, and the lifting track 214 is driven by the lifting cylinder to move upwards and is connected with the far pushing track 23; the bidirectional cylinder 22 drives the far-pushing block 210 to push the outer wire on the lifting rail 214 towards the conveying direction, and the outer wire slides down to the far-pushing rail 23 under the action of the pushing force and slides to the feeding unit at the tail end of the far-pushing rail 23.

(4) When the in-place sensor detects the outer wire and the full-material sensor does not detect the outer wire, the control chip PLC controls the material pushing cylinder to drive the material pushing block 32 to vertically push the outer wire to the inlet of the tapping machine scraper-trough conveyer 4 through the material pushing support 31 to enter the tapping machine scraper-trough conveyer.
