Description

TECHNICAL FIELD

[0001] The present application relates to a kind of silk knot feeding machine, in particular to an automatic silk knot feeding machine and feeding method. BACKGROUND

[0002] The union joint, also known as a by ren, by ren or oil ren, is a commonly used pipe connecting piece that can be easily installed and removed, mainly consisting of a nut, a cloud head and a flat joint. The cloud head is also known as a silk knot. Before the silk knot is assembled into a by ren, the silk knot needs to be placed on a chute that holds the silk knot, and then the silk knot CNC lathe controls the chute filled with silk knots to enter the processing position to complete the turning of the silk knot. At present, there are two ways to load silk knots into the chute of the CNC lathe; one of them is a manual workpiece placement method, which is to manually place each silk knot into the chute of the CNC lathe, and then control the CNC lathe to drive the chute into the processing position to complete the processing of the silk knot. Although each operator can supplement the silk knots in the chute of multiple CNC lathes to maintain the normal operation of multiple CNC lathes, when a CNC lathe fails, the operator needs to handle it in time and cannot place silk knots in the chute of other CNC lathes, which causes other processing equipment to stop processing. Not only is the degree of automation low, but also a large amount of manpower and resources are required, and the production efficiency is low; the other is a vibrating disc feeding method, which automatically and orderly arranges the disordered workpieces in order through vibration and accurately transports them to the chute of the CNC lathe. Compared with the manual workpiece placement method, although the vibrating disc feeding method allows each operator to monitor 2 to 3 CNC lathes and ensures the normal operation of other lathes when one lathe needs maintenance, a large number of silk knots are placed in each vibrating disc during the vibrating disc feeding process, which not only produces a lot of noise but also causes bumps that affect the appearance of the silk knots.

[0003] Therefore, it is a problem for those skilled in the art to produce a silk knot feeding machine with high automation, efficient feeding and stable order. SUMMARY

[0004] The technical problem to be solved by the present application is to provide an automatic silk knot feeding machine with efficient feeding, stable order and high automation.

[0011] The automatic wire section loading machine, direction sensors one and two are arranged in the vertical piece sliding groove; the direction sensors one and two face the front and rear ends of the wire section in the vertical piece sliding groove, and the height of the direction sensors one and two from the lower outlet of the vertical piece sliding groove is matched with the size of the outer peripheral radius of the wire section.

[0012] An automatic wire section loading method, which adopts the wire section loading machine, and the method steps are:

[0013] 1) the yarn section is sent into the feeding end of the material conveying device by the feeding device, and then conveyed to the discharging end by the material conveying device;

[0014] 2) the yarn section falling from the discharging end of the material conveying device enters the vertical piece sliding groove in the posture of two open ends being distributed in front and back, and then slides downward;

[0015] 3) the moving groove cylinder drives the right rotating piece groove or the left rotating piece groove to be aligned with the vertical piece sliding groove; the yarn section sliding in the step 2) falls into the right rotating piece groove or the left rotating piece groove opposite to the vertical piece sliding groove, and then slides downward and rotates from the right rotating piece groove or the left rotating piece groove;

DETAILED DESCRIPTION

[0038] Referring to Figure 1 and Figure 13 , the automatic yarn section feeding machine comprises a feeding bucket 1 and a support 23. The support 23 is composed of a cylindrical supporting rod with supporting legs and a supporting plate horizontally arranged at the upper end of the cylindrical supporting rod. The supporting plate is provided with a feeding device 2, a material conveying device 8, a rotating device 13 and a control circuit. Under the control of the control circuit, the feeding device 2 transports the yarn sections in the feeding bucket 1 into the material conveying device 8, the material conveying device 8 sorts and lowers the yarn sections into the rotating device 13, and the rotating device 13 rotates the yarn sections into the same posture required for processing. The supporting plate is also provided with an upper piece chute 22. The upper piece chute 22 is used to receive the yarn sections after being rotated by the rotating device 13. The yarn sections are of a structure with a thick end and a thin end.

[0039] Referring to Figures 1-7 ​The feeding device 2 of the automatic silk bobbin feeding machine comprises a feeding hopper 3. The feeding hopper 3 is cylindrical, sleeved on the feeding barrel 1, and has an adjusting door 4 opened at the lower side, and a feeding push rod 6 arranged at the lower end inside. The feeding push rod 6 is made of plastic, and has a front end facing the adjusting door 4 and a rear end connected with a feeding cylinder 7. A V-shaped bottom 3-1 is additionally arranged at the bottom of the feeding hopper 3 between the adjusting door 4 and the feeding push rod 6; the V-shaped bottom 3-1 is arranged in the same direction as the feeding push rod 6 and adjacent to the lower side of the feeding push rod 6, and has a front end facing the adjusting door 4. A anti-packing bottom 3-2 is further arranged inside the feeding hopper 3, which is a slope facing the V-shaped bottom 3-1 downward, and the plane where the slope is located is above the feeding push rod 6. The adjusting door 4 is capped with a rubber adjusting door 5. In this way, the silk bobbins in the feeding barrel 1 can fall into the feeding hopper 3, and after falling into the feeding hopper 3, first contact the anti-packing bottom 3-2 facing the V-shaped bottom 3-1 downward, and then slide down on the anti-packing bottom 3-2 to the V-shaped bottom 3-1 between the feeding push rod 6 and the adjusting door 4; on the one hand, the silk bobbins are prevented from directly falling and colliding with the V-shaped bottom 3-1 to cause damage to the shape of the silk bobbins; on the other hand, the silk bobbins can only slide down on the anti-packing bottom 3-2 to the V-shaped bottom 3-1 between the feeding push rod 6 and the adjusting door 4, avoiding the silk bobbins distributed to the two sides relative to the feeding push rod 6, and the feeding push rod 6 cannot push out the silk bobbins to cause packing; then, the feeding cylinder 7 can drive the feeding push rod 6 made of plastic to push the silk bobbins on the V-shaped bottom 3-1 out of the adjusting door 4 along the wall of the V-shaped bottom 3-1, and avoid the feeding push rod 6 from colliding and damaging the silk bobbins when contacting the silk bobbins. Since the adjusting door 4 is capped with the rubber adjusting door 5, the silk bobbins not pushed out of the adjusting door 4 can be pressed back into the adjusting door 4 due to the elasticity of the rubber adjusting door 5.

[0040] Referring to Figure 1 、 2 , 3, 4, 8, 9 and Figure 10The feeding device 8 of the automatic yarn package loading machine comprises a linear vibration feeder 12, and a sorting track 11 is arranged above the linear vibration feeder 12. The sorting track 11 is V-shaped, the bottom of the V-shaped sorting track is matched with the diameter of the end of the yarn package, the front end of the V-shaped sorting track is opposite to the adjusting door 4 in the up-down direction, the rear end of the V-shaped sorting track is opposite to the feeding end of the rotating device 13 in the up-down direction, and one support plate 9-3 is vertically arranged on each side of the V-shaped sorting track. The rear end of each of the two support plates 9-3 is fixedly connected with a guide plate 9-2. The guide plate 9-2 is fixedly connected with a combing air cylinder 9 arranged in front of and behind the guide plate 9-2. The cylinder rod of the combing air cylinder 9 is fixedly connected with a vertically arranged pushing plate 9-1. The pushing plate 9-1 is made of rubber and can move forward and backward in the sorting track 11. The lower end of the pushing plate 9-1 is provided with openings through which the yarn packages in the up-down distribution state pass. In this way, the yarn packages in the downcomer 3 can be transported to the rear end of the sorting track 11 by the linear vibration feeder 12 after falling into the front end of the sorting track 11. Since the V-shaped bottom of the sorting track 11 is matched with the diameter of the end of the yarn package, the yarn packages are transported in a front-rear linear arrangement. During the transportation process, the yarn packages whose opening ends are not in the up-down distribution state can be rolled in the V-shaped sorting track 11 and adjusted to be in the up-down distribution state, the yarn packages whose opening ends are in the up-down distribution state can be transported to the rear end of the sorting track 11 by the pushing plate 9-1, and the yarn packages whose opening ends are not in the up-down distribution state are blocked by the pushing plate 9-1 and pushed back to the front end of the sorting track 11 by the forward movement of the pushing plate 9-1 driven by the combing air cylinder 9 until the yarn packages are adjusted to be in the up-down distribution state and pass through the pushing plate 9-1. Since the pushing plate 9-1 is made of rubber, the pushing plate 9-1 and the pushed yarn packages do not collide and damage the appearance of the yarn packages when the pushing plate 9-1 pushes the yarn packages forward.

[0041] Referring to Figure 1 、 2 , 3, 4, 11 and Figure 12The rotating device 13 of the automatic silk knot loading machine comprises a vertical piece sliding groove 16, a rotating part and a blocking part. The rotating part comprises a moving groove cylinder 17, a right rotating piece groove 20 and a left rotating piece groove 21. The blocking part comprises a blocking piece plate 15 and a blocking piece cylinder 19. The vertical piece sliding groove 16 is a strip-shaped groove with an open front end, and the open end is opposite to the discharging end of the material conveying device 8. The distance between the open end and the groove bottom of the vertical piece sliding groove 16 is matched with the distance between the two openings of the silk knot, and the distance between the two groove walls of the vertical piece sliding groove 16 is matched with the diameter of the outer buckle end of the silk knot. In this way, a silk knot located at the discharging end of the material conveying device 8 can only enter the vertical piece sliding groove 16 and slide down in the posture of the two openings arranged in front and back. The moving groove cylinder 17 is fixed on the bracket 23 in left and right directions, and the cylinder rod of the moving groove cylinder 17 is fixed with the right rotating piece groove 20 and the left rotating piece groove 21, which are vertically distributed below the vertical piece sliding groove 16. The right rotating piece groove 20 is a cylindrical structure with a horizontal right twist of 90° from top to bottom inside. The left rotating piece groove 21 is a cylindrical structure with a horizontal left twist of 90° from top to bottom inside. The inner diameter of the right rotating piece groove 20 and the left rotating piece groove 21 is matched with the silk knot, and can contain the silk knot but cannot rotate arbitrarily. The moving groove cylinder 17 drives the left rotating piece groove 21 and the right rotating piece groove 20 to slide below the vertical piece sliding groove 16 through the stretching of the cylinder rod, so that the upper inlets of the left rotating piece groove 21 and the right rotating piece groove 20 are respectively opposite to the lower outlets of the vertical piece sliding groove 16. The blocking piece plate 15 is horizontally arranged below the vertical piece sliding groove 16 and above the left rotating piece groove 21 and the right rotating piece groove 20. The blocking piece cylinder 19 is fixed on the bracket 23, and the cylinder rod of the blocking piece cylinder 19 is fixed with the blocking piece plate 15 and can drive the blocking piece plate 15 to be pulled out below the vertical piece sliding groove 16. In this way, a silk knot located at the upper and lower distribution state of the rear opening end of the sorting track 11 enters the vertical piece sliding groove 16, and can only enter in the posture of the open end in front and back due to the size limitation of the vertical piece sliding groove 16. Then the silk knot slides down along the vertical piece sliding groove 16 and is blocked by the blocking piece plate 15 at the lower end of the vertical piece sliding groove 16. The moving groove cylinder 17 drives the left rotating piece groove 21 or the right rotating piece groove 20 to correspond to the vertical piece sliding groove 16 according to the front and back orientation of the two openings of the silk knot. Then the blocking piece cylinder 19 pulls out the blocking piece plate 15 below the vertical piece sliding groove 16, and the silk knot falls into the corresponding left rotating piece groove 21 or right rotating piece groove 20. The subsequent falling silk knot can slide out in the same posture according to the different turning directions of the left rotating piece groove 21 or the right rotating piece groove 20. When the left rotating piece groove 21 or the right rotating piece groove 20 is changed, the blocking piece plate 15 is driven by the blocking piece cylinder 19 to block the material.

[0042] Referring to Figure 1 , 2 , 3, 4, 11 and Figure 12, the upper piece chute 22 is a strip-shaped track for the silk section to fall into from the left rotating piece groove 21 or the right rotating piece groove 20. When the upper end of the upper piece chute 22 is adjacent to and opposite to the lower end of the right rotating piece groove 20 or the left rotating piece groove 21, the upper end of the upper piece chute 22 is adjacent to and opposite to the lower end of the right rotating piece groove 20 or the left rotating piece groove 21. At this time, the vertical piece sliding groove 16, the right rotating piece groove 20 or the left rotating piece groove 21 and the upper piece chute 22 can form a through channel for the silk section to fall. In this way, when the upper piece chute 22 is not full of silk sections, the blocking piece cylinder 19 pulls out the blocking piece plate 15 at the lower end of the vertical piece sliding groove 16, and then the silk section at the lower part of the vertical piece sliding groove 16 enters the upper piece chute 22 through the corresponding right rotating piece groove 20 or left rotating piece groove 21; until the upper piece chute 22 is full of materials, the blocking piece cylinder 19 drives the blocking piece plate 15 to cover the lower end of the vertical piece sliding groove 16; at the same time, the linear vibration feeder 12 stops feeding, and the combing cylinder 9 stops driving the lower pushing plate 9-1 to move.

[0043] Referring to Figures 1-13 The control circuit of the automatic silk section feeding machine comprises a CPU 25, a pair of photoelectric sensors 10, a direction sensor one 14, a direction sensor two 18 and a full material sensor 24. The pair of photoelectric sensors 10 are located at the front ends of the two support plates 9-3 to detect whether there is a silk section at the front end of the sorting track 11. The direction sensor one 14 and the direction sensor two 18 are both inductive proximity switches. The direction sensor one 14 and the direction sensor two 18 are opposite to the front and rear ends of the silk section in the vertical piece sliding groove 16, and the height of the direction sensor one 14 and the direction sensor two 18 from the lower outlet of the vertical piece sliding groove 16 is matched with the size of the outer peripheral radius of the end of the silk section. The silk section at the bottom of the vertical piece sliding groove 16 is opposite to the two direction sensors. Since the thicknesses of the two ends of the silk section are different, the thick end can trigger the direction sensor, and the thin end cannot trigger the direction sensor. Thus, the posture of the silk section, whether the thick end is forward or the thin end is forward, can be determined according to the triggering conditions of the two direction sensors. The direction sensor one 14 and the direction sensor two 18 can control the slot moving cylinder 17. The full material sensor 24 is located at the upper end of the upper piece chute 22 to detect whether the upper piece chute 22 is full of silk sections. The signal input end of the CPU 25 is connected with the pair of photoelectric sensors 10, the direction sensor one 14, the direction sensor two 18 and the full material sensor 24, and the signal output end is connected with the discharging cylinder 7, the combing cylinder 9, the linear vibration feeder 12, the slot moving cylinder 17 and the blocking piece cylinder 19.

[0044] Referring to Figures 1-13 The silk section feeding method adopts the automatic silk section feeding machine described above, and the method steps are as follows:

[0045] 1) the yarn section is sent into the feeding end of the conveying device 8 by the feeding device 2. In the conveying process, the front end of the sorting track 11 is detected by the light barrier photoelectric sensor 10. When the light barrier photoelectric sensor 10 detects that the front end of the sorting track 11 is empty, a signal is sent to the CPU 25. The CPU 25 controls the combing air cylinder 9 to start and drives the push plate 9-1 to move forward. When the air cylinder rod of the push plate 9-1 moves forward in the straight state, the light barrier photoelectric sensor 10 detects again whether the front end of the sorting track 11 has yarn sections. When the light barrier photoelectric sensor 10 detects that the front end of the sorting track 11 is empty, a signal is sent to the CPU 25. The CPU 25 controls the discharging air cylinder 7 to drive the discharging push rod 6 to push out the yarn sections located at the adjusting door 4. When the light barrier photoelectric sensor 10 detects that the front end of the sorting track 11 has yarn sections, a signal is sent to the CPU 25. The CPU 25 controls the discharging air cylinder 7 to stop running. Subsequently, the direction sensor one 14 and the direction sensor two 18 detect whether the yarn sections are at the lower end of the vertical sliding groove 16. When the direction sensor one 14 and the direction sensor two 18 do not detect the yarn sections at the lower end of the vertical sliding groove 16, a signal is sent to the CPU 25. The CPU 25 controls the linear vibration feeder 12 to start feeding and drives the push plate 9-1 to move forward. The yarn sections with the opening ends in the up-down distribution state are transported to the rear end of the sorting track 11, and the yarn sections with the opening ends not in the up-down distribution state are pushed to the front end. Then, the yarn sections with the opening ends not in the up-down distribution state are adjusted by the linear vibration feeder 12 until the yarn sections with the opening ends in the up-down distribution state pass through the push plate 9-1;

[0046] 2) Due to the size limitation of the vertical sliding groove 16, the yarn sections falling from the discharging end of the conveying device 8 enter the vertical sliding groove 16 in the posture of two opening ends in front and back distribution, and slide down. Subsequently, the yarn sections are blocked by the blocking plate 15 at the lower end of the vertical sliding groove 16;

[0047] 3) The slot-moving cylinder 17 drives the right-rotating slot 20 or the left-rotating slot 21 to align with the vertical-sliding slot 16; the fullness sensor 24 detects whether the upper-sliding chute 22 is full of yarn; when the fullness sensor 24 detects that the upper-sliding chute 22 is not full of yarn, it sends a signal to the CPU 25, which controls the blocking cylinder 19 to drive the blocking plate 15 to move to open the lower end of the vertical-sliding slot 16, so that the yarns dropped in step 2) fall into the right-rotating slot 20 or the left-rotating slot 21 opposite to the vertical-sliding slot 16 and slide downward and rotate into the same posture from the right-rotating slot 20 or the left-rotating slot 21; when the fullness sensor 24 detects that the upper-sliding chute 22 is full of yarn, it sends a signal to the CPU 25, which controls the blocking cylinder 19 not to pull out the blocking plate 15, and the blocking plate 15 covers the yarns at the lower end of the vertical-sliding slot 16 to prevent the yarns in the vertical-sliding slot 16 from falling down;

[0048] 4) The yarns dropped in step 3) fall into the upper-sliding chute 22 in the same posture after passing through the right-rotating slot 20 or the left-rotating slot 21, until the upper-sliding chute 22 is full, and then the yarns enter the processing position with the upper-sliding chute 22;

[0049] 5) When the posture of the yarns in step 2) changes, it is judged by the direction sensor one 14 and the direction sensor two 18; when the direction sensor one 14 detects that there are yarns at the lower end of the vertical-sliding slot 16, it sends a signal to the CPU 25, which controls the linear-vibration feeder 12 and the combing cylinder 9 to close, and controls the slot-moving cylinder 17 to start, which drives the right-rotating slot 20 to move below the vertical-sliding slot 16; when the direction sensor two 18 detects that there are yarns at the lower end of the vertical-sliding slot 16, it sends a signal to the CPU 25, which controls the linear-vibration feeder 12 and the combing cylinder 9 to close, and controls the slot-moving cylinder 17 to start, which drives the left-rotating slot 21 to move below the vertical-sliding slot 16; so that the left-rotating slot 21 or the right-rotating slot 20 is opposite to the vertical-sliding slot 16.
