The specific embodiment
In order to illustrate in greater detail screw feeding device of the present invention, describe with accompanying drawing.
Transparent view when the 1st figure is the loam cake that has removed screw feeding device of the present invention, the 2nd figure be from directly over the birds-eye view of looking, the 3rd figure is a front elevation, the 4th figure is a right elevation.
Shown in the 1st figure to the 4 figure like that, the screw feeding device 20 of this example has screw resettlement section 22 and arrangement units 23 in the inside of box-shaped enclosure 21.Both are extended longitudinally the median wall 24 that forms by the roughly centre portion of shell 21 and separate, and the substantial middle of this median wall 24 partly is equipped with the discoideus going barrel 25 as delivery unit.
Above-mentioned screw resettlement section 22 has three receiving spaces that sidewall surrounds by median wall 24 that comprises above-mentioned going barrel 25 and shell 21.And, be equipped with laminal base plate 26 on the bottom surface of screw resettlement section 22.The front and back of this base plate 26 are inclined upwardly, and make the centre portion step-down, and the integral body of base plate 26 is to the lopsidedness of going barrel 25, even make Screw 27 amounts that are housed in the screw resettlement section 22 seldom also slide to going barrel 25 1 sides easily simultaneously.
Above-mentioned going barrel 25 is driven by the motor 30 that next-door neighbour's screw resettlement section 22 sets, and is such shown in the 1st figure and the 2nd figure, by the propulsive effort that is crossed on the driving connecting gear 31 transmission motors 30 between going barrel 25 and the motor 30.Driving connecting gear 31 is made of belt pulley 33 on the S. A. 32 of output shaft that is installed in motor 30 and going barrel 25 and the belt 34 that is crossed between the output shaft of this belt pulley 33 and above-mentioned motor 30.Going barrel 25 can set rotatably along median wall 24, and 4 places around it offer the through hole 35 of the rectangular shape of section.The shape of all these through holes 35 is all identical, but straight line does not connect the front-back of going barrel 25, but shown in the 4th figure and the 5th figure internal face 36a, the 36b about like that along the hand of rotation of going barrel 25 tilted rearward gradually from the front to the back.And, the upper wall surface 37 of through hole 35 also from the front of going barrel 25 to the back to S. A. 32 lopsidedness.
Above-mentioned going barrel 25 is rotation like that in the counterclockwise direction shown in the 4th figure and the 5th figure, Screws 27 in the screw resettlement section 22 are ladled out play in the through hole 35, be sent in the arrangement units 23, but tilting action owing to this moment of base plate 26 of such screw resettlement section 22 shown in the 6th figure, Screw 27 enters in the through hole 35 easily, left and right sides inwall 36a, 36b owing to through hole 35 tilts to the direction that dips Screw 27 easily simultaneously, so can easily dip a plurality of Screws 27 in the through hole 35.And in the rotation of going barrel 25 was sent to Screw 27 process in the arrangement units 23, it is unrestrained that the inclination of internal face 36a, the 36b of above-mentioned through hole 35 is difficult to from through hole 35 Screw 27.And when the rotation of going barrel 25 made through hole 35 arrive the position of arrangement units 23, like that, because the upper wall surface 37 of through hole 35 is downward-sloping, so the Screw 27 in the through hole 35 successfully was slipped in the arrangement units 23 shown in the 7th figure.Like that, in screw resettlement section 22, back one side of going barrel 25 is blocked by longitudinal wall 28 shown in the 6th figure, has prevented to ladle out the Screw 27 that plays in the through hole 35 and has been left out to back one side of through hole 35.Though above-mentioned example explanation is the situation that going barrel 25 is provided with 4 through holes 35, the quantity of through hole 35 has no particular limits.Can do suitable change according to the kind of screw and the situations such as rotative speed of size and going barrel 25, for example also can use to have formed, perhaps than the going barrel of 6 or 8 through holes more than 4 than 42 of lacking or 3.
Above-mentioned arrangement units 23 shown in the 1st to the 3rd figure, have like that be arranged on than the high locational arrangement units in advance 40 of the base plate 26 of screw resettlement section 22 and with these arrangement units 41 of being provided with continuously of arrangement units 40 in advance.In advance arrangement units 40 comprise the plate part 42 of a plurality of Screws 27 that acceptance discharges from going barrel 25, the guide groove in advance 43 of groove shape that the Screw 27 that discharges is arranged along the periphery of plate part 42 rows ofly, be used for making from this in advance the guide groove 43 unrestrained Screw 27 turn back to top sliding part 44 in the screw resettlement section 22.Above-mentioned plate part 42 has a down dip towards guide groove 43 1 side direction in advance like that shown in the 3rd to the 7th figure, can be effectively collects in advance in the guide groove 43 being discharged into Screw 27 on the plate part 42.
Above-mentioned guide groove 45 is formed on an end of tabular component, with overlap on this tabular component, that the approximate L shaped pressing plate 50 1 of section is reinstated Screw 51 is fixing, can take off.Above-mentioned pressing plate 50 has the longitudinal wall 53 of 45 1 edge-on of adjacent guide grooves.Therefore, the Screw 27 of misarrangement is revised its orientation by contacting with above-mentioned longitudinal wall 53, and the Screw 27 of perhaps revising difficulty falls from slotted portion 49.Because tabular component can take off, the therefore groove width by preparing a plurality of guide grooves 45 or the different member of kerf width of slotted portion 49 can be replaced according to the difference of the kind of Screw or size etc.The lower end of above-mentioned bottom sliding part 47 links to each other with screw resettlement section 22, Screw 27 guider screw resettlement sections 22 that will landing is got off from top sliding part 44 and guide groove 45.
In the screw feeding device 20 of this example, jagged cam 56 is installed on the output shaft of above-mentioned motor 30, roller 57 rotates at this serrated face, makes device integral body along the fore-and-aft direction slight vibration thus.Under the effect of this slight vibration, be arranged on guide groove 43, guide groove 45 and the guide rail 48 in advance and the Screw 27 that is directed moves gradually and advances.In addition, this example shown in the 4th figure like that, from the rear end of guide groove 43 in advance through guide groove 45 to the top of guide rail 48 relative horizon 61 downward-sloping, the inclination angle is θ, thus above-mentioned microvibration makes Screw 27 progressive motions effectively.
According to the 6th figure to the 10 figure the screw feeding device 20 that said structure constitutes is described below.Above-mentioned screw feeding device 20 is arranged on the assigned line of miniaturized electronics etc. for example.At first, open the loam cake (not illustrating among the figure) of the shell 21 that the top of screw resettlement section 22 is provided with, a plurality of Screws 27 are dropped in the screw resettlement sections 22.The length of the screw rod 27a of this Screw 27 is about 1: 1 with the diameter ratio of nut 27b.Then, open main switch (not illustrating among the figure) drive motor 30, make going barrel 25 rotations.Shown in the 6th figure, by the rotation of going barrel 25, Screw 27 is scooped in 4 through holes 35 in succession.The Screw 27 that is scooped into is rotated drum 25 and is sent to the top, then shown in the 7th figure like that, be discharged into from back one side of through hole 35 on the plate part 42 of arrangement units 40 in advance.
Like that, because plate part 42 is to guide groove 43 lopsidedness in advance, so Screw 27 gathers guide groove 43 1 sides in advance easily shown in the 7th figure.The Screw 27 that compiles is subjected to the states with accumbency of acting in the guide groove 43 in advance of the whole little vibration of device to be row one by one to arrange.The discrete Screw 27 of proper alignment does not slip over the bottom sliding part 47 that top sliding part 44 is shifted to arrangement units 41 on guide groove 43 in advance.
Though Screw 27 its nut 27b that proper alignment moves on guide groove 43 in advance towards having nothing in common with each other, but shown in the 8th figure and the 9th figure, in the time of on moving on to guide groove 45, because the effect of step 60,, in guide groove 45, forwards arranged under such state and moving for all backwards by neat.Even though axially the departing from a bit also and can be directed with the groove direction of guide groove 45 of Screw 27 on moving to guide groove 45 time, when the slotted portion 49 by guide groove 45, as long as axially some departs from, Screw 27 will fall down from slotted portion 49.Therefore, when being about to arrive guide rail 48, be arranged in Screw 27 on the guide groove 45 axially all with the groove direction basically identical of guide groove 45.The Screw 27 that falls down from above-mentioned slotted portion 49 and turn back to the screw resettlement section 22 from the dip plane that the Screw 27 that sliding part 44 landings in top are got off slips over bottom sliding part 47 with keeping intact is used for transmitting next time.
Though in guide groove 43 and guide groove 45 in advance, Screw 27 forms a line with the state of accumbency, but when the terminal from guide groove 45 moves on on the guide rail 48, like that, the screw rod 27a that is in Screw 27 is inserted in the gap 55 of guide rail 48, nut 27b is by left and right rail member 48a, 48b supporting and sagging state shown in the 10th figure.The Screw 27 that nut 27b is bearing on the guide rail 48 is directed with the state of file, moves down to the top of guide rail 48 successively.In addition, because Screw 27 is arranged in guide groove 45 with screw rod 27a state forward and is moved, therefore screw rod 27a be inserted into when going in the gap 55 of guide rail 48 extremely smooth, even but the nut 27b of Screw 27 forward, do not influence in the gap 55 that screw rod 27a inserts guide rail 48 yet.
The screw retrieval unit that the Screw 27 that is moved successively by guide rail 48 guiding does not illustrate from the top arrival figure of guide rail 48 takes out singly by operator's bit manipulation.
The 11st figure and the 12nd figure are the figure of expression the 2nd example of the present invention.The screw feeding device 20a of this example passes to going barrel 25 with size 2 belt pulley 33a, 33b with the propulsive effort of motor 30, is provided with belt 34a, 34b striding respectively between the output shaft of motor 30 and the small belt pulley 33a and between the S. A. of small belt pulley 33a and the big belt pulley 33b.The S. A. of big belt pulley 33b is coaxial with the S. A. 32 of going barrel 25.Like this, by using size 2 belt pulley 33a, 33b, can easily adjust the rotative speed of going barrel 25.
And the screw resettlement section 20a of this example utilizes electromagnet 70 to make the whole little vibration of device.This electromagnet 70 is installed on the fixing base 71 of shell 21 by carriage 72 shown in the 11st figure like that, and only separates very little configuration with gap between the oscillating plate 73.Oscillating plate 73 is for being installed to above-mentioned arrangement units 23 by carriage 75 member on the supporting arm 74 that is supported on the shell 21.Therefore, when electromagnet 70 energisings, oscillating plate 73 little vibrations, this little vibration passes to arrangement units 23 by carriage 75 and supporting arm 74, makes arrangement units in advance 40 such shown in the 1st figure, arrangement units 41 and guide rail 48 along the little vibration of fore-and-aft direction.Thus, be arranged on guide groove 43, guide groove 45 and the guide rail 48 in advance and the Screw that is directed can move successively and advances.The situation of using electromagnet 70 as this example rotates the situation of vibrative previous example different with making roller 57 on the surface of jagged cam 56, can suppress the noise that whole device sends significantly.
And, such shown in the 12nd figure, the screw feeding device 20a of this example has a pair of detecting sensor 77a, 77b in the position configuration in the outside of the top of guide rail 48,2 guide rail component 48a, 48b, disposes the killer member 78 in the gap 55 of stopping up guide rail 48 simultaneously.This killer member 78 is made of the leaf spring that the rear end is fixed on the lateral surface of a guide rail component 48a, stops up the gap 55 of guide rails 48 with the curve 79 of top formation.
Owing to possess such structure, the Screw 27 that moves to the top of guide rail 48 is detected by above-mentioned detecting sensor 77a, 77b.Whereby, the rotation of going barrel 25 is interrupted in the driving that stops motor 30, and the conducting of tripping magnet 70 simultaneously stops little vibration of oscillating plate 73.Therefore, can not be detained a large amount of Screw 27 on the arrangement units 23, guide rail 48 can not stopped up by Screw 27 yet certainly.The Screw 27 on guide rail 48 tops connects with the curve 79 of killer member 78, rests on this position.Because curve 79 elastic deformations of killer member 78, so the front end of the enough corkscrews of operator's energy plucks out Screw 27 at an easy rate from guide rail 48.When from guide rail 48, plucking out Screw 27, drive above-mentioned motor 30, and give electromagnet 70 energisings, Screw 27 begins to move successively on guide rail 48 once more thus.
The 2nd example of the present invention also has feature on the structure of arrangement units 41 except that said structure.That is, shown in the 12nd figure to the 14 figure like that, for offer at the tabular component 50a upper edge guide groove 45 that forms guide groove 45 as the slotted hole 80 of removing part, make this slotted hole 80 below the structure that is communicated with bottom sliding part 47.Above-mentioned slotted hole 80 clips the opposite side that guide groove 45 is arranged on slotted portion 49.Therefore there is not the such longitudinal wall of example before this along guide groove 45.In addition, it is fixing that tabular component 50a and pressing plate 50 1 are reinstated Screw 51, can take off.
Therefore, when Screw 27 passes through guide groove 45, the Screw 27 that orientation departs from not only can be removed by slotted portion 49, can also be removed by slotted hole 80, particularly when the nut 27b of Screw 27 passes through under the state of the direction of slotted hole 80, fall in the slotted hole 80 from the direction of nut 27b, bottom sliding part 47 is crossed in landing like this.Like this, even the orientation left and right deviation that can strengthen Screw 27 situation seldom or the measuring ability of the overlapping situation of a plurality of screw can further improve and make Screw move to reliability on the guide rail 48 from guide groove 45.
The 15th figure and the 16th figure are the figure of other examples of the arrangement units 41 of above-mentioned the 2nd example of expression, groove part 81 is set replaces above-mentioned slotted hole 80.As the groove part 81 of removing part is not to be set directly on the tabular component 50a that is formed with above-mentioned guide groove 45, but an overlapping side that is placed in the accessory plate 50b above this tabular component 50a is cut into rectangle.Therefore, tabular component 50a and accessory plate 50b is overlapping, overlapping thereon again pressing plate 50, and can fix with Screw 51, formed the groove part 81 that is provided with the step that equates with the thickness of accessory plate 50b along guide groove 45 thus. with taking offThis groove part 81 also with above-mentioned slotted hole 80 the same opposite sides that are arranged on slotted portion 49, clip guide groove 45, length is shorter than the length of slotted portion 49.
The groove part 81 and the above-mentioned slotted hole 80 that constitute like this have same purpose.That is,,, then when 2 Screws 27 pass through guide groove 45 with overlapping state, exist the nut 27b of Screw 27 to prop up the possibility of on longitudinal wall 53, like this passing through if there is longitudinal wall 53 side of adjacent guide groove 45 as above-mentioned the 1st example.This example is owing to be bearing in Screw 27 on the longitudinal wall 53 has lost nut 27b at groove part 81 places support, having lost original posture turns over and falls in the groove part 81, again owing to contact with the turning 82 in groove part 81 downstreams, quilt ejects guide groove 45 and has fallen, and slips down from bottom sliding part 47 with keeping intact.Therefore, do not removed and remaining Screw 27 all is in the state of proper alignment towards guide rail 48 by groove part 81.
