Description
Technical Field
The invention relates to fastener processing equipment, in particular to a screw feeding system.
Background
Referring to fig. 10, in order to prevent the screw from being loosened accidentally after the screw is locked, a portion of the screw S is glued before shipment, that is, a glue with anti-loosening effect is coated on the thread of the screw S. When the glue coating process is performed, the screw is fed onto a strip-shaped conveying belt 92 by a flat feeding device 91, and the conveying belt 92 conveys the screw to a glue coater (not shown) for glue coating operation.
In order to ensure that the screw S is not separated from the conveyor belt 92 during the moving and gluing process, the adhesive tape 93 is adhered to the surface of the conveyor belt 92, and the head of the screw S is adhered to the conveyor belt 92 by the adhesive of the adhesive tape 93, so that the screw S is fixed on the conveyor belt 92.
However, the existing screw glue application process has the following drawbacks:
First, the adhesive tape 93 fixes the screw S by sticking, but the fixing force provided by sticking is very limited, so that the screw S cannot be firmly fixed on the conveyor belt 92.
Second, before processing, it is necessary to adhere the adhesive tape 93 to the conveyor belt 92 in advance, which results in a long processing preparation time.
Third, the viscosity of the adhesive tape 93 decreases with the use time, so that the screw S on the conveyor belt 92 is easy to be skewed due to the viscosity degradation of the adhesive tape 93, and the processing quality is affected. In addition, the adhesive tape 93 is often replaced due to the deterioration of the adhesion, which is troublesome.
Fourth, the feeding speed of the screw S to the conveyor belt 92 via the flat feeding device 91 cannot be excessively high, so that the overall efficiency is poor.

Detailed Description
Referring to fig. 1 to 4, the automatic feeding system of the fastener of the present invention is used for conveying a fastener F, and the fastener F is preferably a screw. The automatic fastener feeding system comprises an input mechanism 10, an output mechanism 20 and a material moving device 30.
The input mechanism 10 has a fastener output end 11 at one end, and the input mechanism 10 can convey the fastener F to the fastener output end 11. Specifically, the input mechanism 10 can arrange the fasteners F closely along a straight line, and feed the aligned fasteners F one by one toward the fastener output end 11. The input mechanism 10 is substantially the same as the flat feeding device 91 in the prior art, so details are not repeated.
The output mechanism 20 has an output member 21, an output driving device 22 (shown in fig. 1), and an output negative pressure generator 23 (shown in fig. 4); and in this embodiment, further has an output negative pressure distribution box 24.
Referring to fig. 4 and 9, the output member 21 extends along an output direction D (shown in fig. 4). The output member 21 is formed with a plurality of receiving channels 211, the receiving channels 211 are independent from each other, and two ends of each receiving channel 211 are respectively provided with a fastener adsorption port 212 and a negative pressure outlet port 214. The negative pressure outlet 214 communicates with the output negative pressure generator 23, and the fastener suction openings 212 are arranged at intervals along the output direction D. The output negative pressure generator 23 makes the fastener suction opening 212 have a negative pressure suction effect, and can suck and fix the fastener F on the fastener suction opening 212.
The output driving device 22 drives the output member 21 to move the fastener suction opening 212 in the output direction D. The fastener suction opening 212 preferably has a circumferential groove 2121 formed at the opening periphery, and the groove 2121 is adapted to receive the fastener F. A ring groove 2121 is formed at the opening periphery of the fastener suction opening 212, which is equivalent to a horn-shaped opening of the fastener suction opening 212.
In this embodiment, the output member 21 is a flexible conveying belt encircling an oval shape, and one end of each receiving channel 211 forms the fastener absorbing openings 212 on the outer ring surface of the output member 21, i.e. the fastener absorbing openings 212 are arranged at intervals along the extending direction of the output member 21; the other end of the receiving channel 211 forms a negative pressure outlet 214 on a negative pressure side 213 of the output member 21. The output driving device 22 drives the output member 21 to move around, so that the fastener suction opening 212 on the top surface of the output member 21 moves in the output direction D. In other embodiments, the output member 21 is not limited to being round in an oval shape, and may have different shapes depending on the structure of the conveyor belt.
In the present embodiment, the material receiving channel 211 is connected to the output negative pressure generator 23 through the output negative pressure distribution box 24, but not limited to this. The output negative pressure distribution box 24 is a hollow housing and extends in the output direction D. The output negative pressure distribution box 24 is provided on one side of the output member 21 so as not to move with the output member 21.
The output negative pressure distribution box 24 has an output negative pressure outlet 241 and an output negative pressure communication port 242 for communicating with the output negative pressure generator 23. The output negative pressure communication port 242 is immediately adjacent to the negative pressure side 213 of the output member 21, and extends in the output direction D. The output negative pressure communication port 242 is in close proximity to the negative pressure side 213 of the output member 21 to reduce gas leakage to maintain negative pressure within the output negative pressure distribution box 24. The negative pressure outlet end 214 of the receiving passage 211 positioned on the top surface of the output member 21 is opposite to the output negative pressure communication port 242 and communicated with the output negative pressure generator 23.
In the present embodiment, the output negative pressure distribution box 24 has a negative pressure equalizing structure 243 therein, and the negative pressure equalizing structure 243 has an outlet 244 formed thereon, and the outlet 244 extends along the output direction D. The negative pressure equalizing structure 243 divides the internal space of the output negative pressure distribution box 24 into an output negative pressure equalizing chamber 245 and an input negative pressure equalizing chamber 246, wherein the output negative pressure equalizing chamber 245 is communicated with the output negative pressure air outlet 241, one of two opposite sides of the input negative pressure equalizing chamber 246 is communicated with the output negative pressure communicating opening 242, and the other side is communicated with the output negative pressure equalizing chamber 245 through the outlet 244 (namely, the outlet 244 is positioned at one side of the input negative pressure equalizing chamber 246 opposite to the output negative pressure communicating opening 242); the cross-sectional width of the inlet plenum 246 tapers from the center toward opposite sides. By providing the negative pressure equalizing structure 243, the negative pressure generated by the output negative pressure generator 23 can be uniformly distributed to each receiving passage 211, so that the negative pressure adsorption forces generated by each receiving passage 211 are approximately equal.
Referring to fig. 3 to 5, the aforesaid material transferring device 30 is connected to the input mechanism 10 and the output mechanism 20. The material transferring device 30 has a base 31, a plurality of material transferring pipes 32, a material transferring negative pressure generator 33, a material transferring positive pressure generator 34 and a power unit 35, and further has a center column 36, a sleeve 37, a positive pressure distribution box 38 and a material transferring negative pressure distribution box 39 in this embodiment.
The power unit 35 is disposed on the base 31, and the power unit 35 is specifically a motor. A central column 36 is secured to the base 31 and extends upwardly. The sleeve 37 is disposed on the power unit 35 and rotatably sleeved outside the center post 36, and the sleeve 37 can be driven by the power unit 35 to rotate around its center line. The top of the center post 36 protrudes upward from the collar 37, and the portion of the center post 36 protruding upward from the collar 37 defines a mounting section 361.
The plurality of transfer tubes 32 are spaced around the centerline of the sleeve 37. Each of the moving pipes 32 has an outer end opening 321 and an inner end opening 322 at opposite ends, and the inner end openings 322 are disposed on the sleeve 37 and exposed on a communication surface of the sleeve 37, i.e. the inner end openings 322 are not shielded by the communication surface, so that air can enter or leave the moving pipe 32 from the inner end openings 322. The communication surface is the top surface of the sleeve 37 in the present embodiment, but not limited to this, and the communication surface may be other outer surfaces of the sleeve 37, such as an outer ring surface.
When the sleeve 37 is driven to rotate by the power unit 35, the outer end opening 321 of the feed tube 32 moves along a circular feed path P (shown in fig. 4) and passes over the fastener output end 11 of the input mechanism 10 and over the path of action of the fastener suction opening 212 of the output mechanism 20. More specifically, the fastener output end 11 is located on the material moving path P of the outer end opening 321 when viewed from the top side (as shown in fig. 4), and the action path of the fastener adsorbing port 212 is a tangent line of the material moving path P of the outer end opening 321. In other embodiments, the material moving path P is not limited to a circle, and may have different shapes according to the system structure.
The manner in which the power unit 35 drives the moving tube 32 is not limited to the above, and only the power unit 35 can drive the moving tube 32, and the outer opening 321 of the moving tube 32 is selectively located at the fastener adsorbing port 212 corresponding to the fastener output end 11 of the input mechanism 10 or one of the material receiving channels 211 of the output mechanism 20. In other words, the power unit 35 only needs to drive the material moving pipe 32 to rotate or move, so that the outer end opening 321 can move between the fastener output end 11 and one of the material receiving passages 211 of the output mechanism 20 in a circulating manner.
The inner end opening 322 of each material moving pipe 32 is selectively communicated with the material moving negative pressure generator 33 or the material moving positive pressure generator 34, so that the outer end opening 321 of the material moving pipe 32 can optionally absorb or blow away the fasteners absorbed by the material moving pipe. In the present embodiment, the inner end opening 322 of the material moving tube 32 is connected to the material moving positive pressure generator 34 in a specific angle range through the positive pressure distribution box 38, and is connected to the material moving negative pressure generator 33 in other angle ranges through the material moving negative pressure distribution box 39, as will be described below.
Referring to fig. 3, 5 and 6, a negative pressure distribution box 39 is disposed on the central column 36 and is adjacent to the communication surface of the sleeve 37. The negative pressure distribution box 39 is a hollow shell, and has a negative pressure outlet 391, a negative pressure inlet 392 and a negative pressure equalizing structure 393. The negative transfer pressure air outlet 391 communicates with the negative transfer pressure generator 33. The material transferring negative pressure air inlet 392 is an arc through hole which is closely adjacent to the communication surface of the sleeve 37 and is opposite to the inner end openings 322 of the plurality of material transferring pipes 32; a plurality, i.e., two or more, of the transfer tubes 32 are not all included. Specifically, negative pressure air inlet 392 is a through hole extending approximately 270 degrees in an arc.
When the sleeve 37 rotates, the inner end openings 322 of all the transfer tubes 32 sequentially pass through the transfer negative pressure inlet 392, so that the transfer negative pressure generator 33 is communicated through the transfer negative pressure inlet 392. Because the material moving pipe 32 rotates due to the fixed position of the material moving negative pressure air inlet 392, the material moving pipe 32 which is actually rotated to the angle range of the material moving negative pressure air inlet 392 is communicated with the material moving negative pressure generator 33 through the material moving negative pressure air inlet 392 to form a suction pipe. The negative pressure distribution box 39 is not limited to be arranged on the central column 36, and only needs to be connected with the base 31 in a non-rotatable way.
Referring to fig. 5 to 7, the negative pressure equalizing structure 393 is disposed in the material transferring negative pressure distribution box 39, and a first negative pressure equalizing hole 394 and a plurality of second negative pressure equalizing holes 395 are formed therethrough. The first negative pressure equalizing hole 394 is elongated and extends along the extending direction of the negative pressure inlet 392, and specifically is an elongated hole extending approximately 270 degrees in an arc shape. In this embodiment, the first negative pressure equalizing hole 394 overlaps the negative pressure inlet port 392 from above. The second negative pressure equalizing holes 395 are provided at intervals along the extending direction of the negative pressure air inlet 392.
The negative pressure equalizing structure 393 divides the internal space of the material moving negative pressure distribution box 39 into a negative pressure air outlet equalizing chamber 396 and a negative pressure air inlet equalizing chamber 397. The negative pressure air outlet equalizing chamber 396 is communicated with the material moving negative pressure air outlet 391, one of two opposite sides of the negative pressure air inlet equalizing chamber 397 is communicated with the material moving negative pressure air inlet 392, and the other side is communicated with the negative pressure air outlet equalizing chamber 396 through a first negative pressure equalizing hole 394 and a second negative pressure equalizing hole 395. The cross-sectional width of the negative pressure intake plenum 397 tapers from the center toward the opposite sides. Referring to FIG. 5, the second negative pressure equalizing aperture 395 preferably extends in an on-line direction along opposite sides of the negative pressure inlet equalizing chamber 397; the second negative pressure equalizing hole 395 extends along the on-line direction of the opposite sides of the negative pressure inlet equalizing chamber 397, that is, the second negative pressure equalizing hole 395 extends along the on-line direction of the material moving negative pressure inlet 392 and the negative pressure outlet equalizing chamber 396, so that the second negative pressure equalizing hole 395 extends substantially along the flow direction of the air flow; more specifically, the second negative pressure equalizing hole 395 extends up and down. By providing the negative pressure equalizing structure 393, the negative pressure generated by the material moving negative pressure generator 33 can be uniformly distributed to the inner end openings 322 of the material moving pipes 32, so that the negative pressure adsorption force generated by the material moving pipes 32 is approximately equal.
Referring to fig. 3, 5 and 6, a positive pressure distribution box 38 is disposed on the central column 36 and is adjacent to the communication surface of the sleeve 37. The positive pressure distribution box 38 is a hollow housing and has a positive pressure inlet 381, a positive pressure outlet 382, and a positive pressure equalizing structure 383. The positive pressure air inlet 381 is communicated with the material moving positive pressure generator 34. The positive pressure air outlet 382 is an arc through hole which is closely adjacent to the communication surface of the sleeve 37 and simultaneously faces the inner end openings 322 of the plurality of material moving pipes 32; a plurality, i.e., two or more, of the transfer tubes 32 are not all included. Specifically, the positive pressure outlet 382 is an arcuate through hole extending about 90 degrees in an arc.
When the sleeve 37 rotates, the inner end opening 322 of the material moving pipe 32 sequentially passes through the positive pressure air outlet 382, so that the material moving positive pressure generator 34 is communicated through the positive pressure air outlet 382. Because the positive pressure outlet 382 is fixed in position and the moving tube 32 rotates, the moving tube 32 actually rotates to the angle range of the positive pressure outlet 382 and is communicated with the positive pressure generator 34 through the positive pressure outlet 382 to form a blowing tube. The positive pressure distribution box 38 is not limited to the fixed center post 36, and may be connected to the base 31 in a non-rotatable manner.
Referring to fig. 6-8, a positive pressure equalizing structure 383 is disposed in the positive pressure distribution box 38, and the positive pressure equalizing structure 383 is substantially identical to the negative pressure equalizing structure 393. The positive pressure equalizing structure 383 is formed with a first positive pressure equalizing hole 384 and a plurality of second positive pressure equalizing holes 385. The first positive pressure equalizing hole 384 is elongated and extends in the direction in which the positive pressure outlet 382 extends. The second positive pressure equalizing holes 385 are arranged at intervals along the extending direction of the positive pressure outlet 382.
The positive pressure equalizing structure 383 divides the interior space of the positive pressure distribution box 38 into a positive pressure outlet equalizing chamber 386 and a positive pressure inlet equalizing chamber 387. The positive pressure inlet plenum 387 communicates with the positive pressure inlet 381. One of two opposite sides of the positive pressure air outlet equalizing chamber 386 is communicated with the positive pressure air outlet 382, and the other side is communicated with the positive pressure air inlet equalizing chamber 387 through a first positive pressure equalizing hole 384 and a second positive pressure equalizing hole 385. The cross-sectional width of the positive pressure outlet plenum 386 tapers from the center toward the opposite sides. The second positive pressure equalization holes 385 preferably extend in a direction on-line with opposite sides of the positive pressure outlet equalization chamber 386; the second positive pressure equalizing hole 385 extends along the on-line direction of the two opposite sides of the positive pressure outlet equalizing chamber 386, that is, the second positive pressure equalizing hole 385 extends along the on-line direction of the positive pressure outlet 382 and the positive pressure inlet equalizing chamber 387, so that the second positive pressure equalizing hole 385 extends substantially along the flow direction of the air stream; more specifically, the second positive pressure equalizing hole 385 extends upward and downward. By providing the positive pressure equalizing structure 383, the positive pressure generated by the positive pressure generator 34 can be uniformly distributed to the inner end openings 322 of the respective transfer pipes 32, so that the positive pressure blowing forces generated by the respective transfer pipes 32 are approximately equal.
Referring to fig. 1 and 4, when the present invention is used, the power unit 35 drives the sleeve 37 to rotate, so that the outer end opening 321 of each material moving pipe 32 moves along the circular material moving path P, and the inner end opening 322 of each material moving pipe 32 passes through the positive pressure air outlet 382 of the positive pressure distribution box 38 and the material moving negative pressure air inlet 392 of the material moving negative pressure distribution box 39 in turn along with the rotation of the sleeve 37. When the position of the moving pipe 32 corresponds to the fastener output end 11, the inner end opening 322 of the moving pipe 32 is opposite to the moving negative pressure air inlet 392 of the moving negative pressure distribution box 39, so that the outer end opening 321 of the moving pipe 32 generates negative pressure, and the fastener F of the fastener output end 11 is adsorbed by the outer end opening 321 of the moving pipe 32. When the same material moving pipe 32 rotates to the position corresponding to the fastener adsorbing port 212 of the output mechanism 20, the inner end opening 322 of the material moving pipe 32 is opposite to the positive pressure air outlet 382 of the positive pressure distribution box 38, so that the outer end opening 321 of the material moving pipe 32 generates positive pressure air blowing, and further the fastener F corresponding to the fastener adsorbing port 212 is blown out of the outer end opening 321 of the material moving pipe 32, and the fastener F is adsorbed by the corresponding fastener adsorbing port 212. Finally, the fastener F is driven by the output member 21 to move in the output direction D to a processing machine (not shown) for processing.
In summary, by arranging the output negative pressure generator 23 and the material transferring negative pressure generator 33, the fastener F is absorbed by the negative pressure and firmly fixed on the output member 21 and the material transferring pipe 32 in the moving process, so that the effect of fixing the fastener F is more reliable, the processing preparation time can be saved, and the maintenance and repair are more time-saving and labor-saving.
The present invention is not limited to the above-mentioned embodiments, but is not limited to the above-mentioned embodiments, and any person skilled in the art can make some changes or modifications to the equivalent embodiments without departing from the scope of the technical solution of the present invention, but any simple modification, equivalent changes and modifications to the above-mentioned embodiments according to the technical substance of the present invention are still within the scope of the technical solution of the present invention.
