The platform of sweep
The platform 112 of the sweep 110 (Fig. 1) of conveyer system 100 will be described now.Should be noted that and will describe several different embodiments of flat-bed, these embodiments comprise the embodiment of rolling-ball unit 120 recessed platforms 112 and the embodiment that rolling-ball unit 120 is stretched out from platform surface.Sweep 110 will be described in more detail after the description of finishing motor-driven roller.
Fig. 9 is the section drawing of the part of platform 112.As shown in Figure 9, platform has upper surface 348 and lower surface 349.Refer again to Fig. 1, platform 112 has hole or the opening that a plurality of its sizes can be held rolling-ball unit 120.Opening 350 other opening in can illustration platform 112.For the sake of clarity, remove cooresponding ball and only show opening 350.As can be seen from Figure 9, opening 350 can comprise the through hole 352 that extends through platform 112.Hole 352 comprises counterbore part 354.Hole 352 can be limited by the circumferential surface 356 with diameter S, and counterbore part 354 can limit by the circumferential surface 358 with diameter T and by annular lower surface 360.Annular lower surface 360 can anomaly platform 112 upper surface 348 1 segment distance U.
With reference to the rolling-ball unit 200 of Fig. 2, the diameter S of through hole 352 can be a bit larger tham the diameter R (Fig. 2) of cup-shape member outside face 254 in addition.Therefore, when the cup 212 of rolling-ball unit 200 was installed in the opening 350, cup-like portion 212 can easily be installed into the through hole 352 of platform 112.The diameter T of counterbore part 354 can be a bit larger tham the diameter V of cap flange 264 (Fig. 5).As described in greater detail, diameter V makes rolling-ball unit 200 be convenient to inject opening 350.
For the rolling-ball unit 200 with Fig. 2 is installed into opening 350, can at first rolling-ball unit 200 be placed on the opening 350, mobile along being directed downwards shown in the arrow among Fig. 9 362 then, rolling-ball unit cup-like portion 212 is moved by the through hole 352 of opening 350.This moves downward the annular lower surface 360 that the lower surface 266 that lasts till rolling-ball unit cap 214 (Fig. 2 and 6) contacts counterbore part 354.In this case, O shape among Fig. 2 circle 328 will be crushed between the circumferential surface 356 of the outside face 254 of cup-like portion 212 (Fig. 3 and 5) and through hole 352, thereby rolling-ball unit 200 is remained in the opening 350.O shape circle 328 also can be pressed between the groove 252 and circumferential surface 356 of outside face 254.Alternately, rolling-ball unit 200 can remain in the opening 350 by any traditional approach.
Other embodiment of installing comprises and is spirally connected or otherwise rolling-ball unit is attached to platform 112.In some embodiments, cap 214 is integral on the platform.Cup-like portion 212 can be spirally connected or otherwise be attached to cap 214 then.
The thickness W of the rolling-ball unit flange 260 of Fig. 6 can be basic identical with the degree of depth U of counterbore part 354; Thereby, when as above-mentioned mode when installing, the upper surface 264 of rolling-ball unit flange 260 will with the upper surface 348 basic coplanes of platform 112.
Figure 10 illustrates the alternative arrangement mode of rolling-ball unit 200 being put into platform 112.Among Figure 10, illustrate in the opening 350 that rolling-ball unit 200 is installed in platform 112.For illustrative purposes, platform 112 illustrates with the form of section, and that rolling-ball unit 200 does not have is shown in section.Remaining opening can form with the essentially identical mode of following description in the platform 112.
As shown in Figure 9, the through hole among Figure 10 352 can pass completely through platform 112.Yet in the embodiment of Figure 10, the counterbore part 354 that is shown among Fig. 9 can be saved.With reference to Figure 10, through hole 352 can be limited by the circumferential surface 356 with diameter S.The diameter S of through hole 352 can be a bit larger tham the diameter R (Fig. 3) of cup-shape member outside face 254.The distance that the thickness Z of platform 112 may be selected to be between the lower surface 266 with O shape circle 328 and cap 214 is identical.In some embodiments, thickness Z can be a bit larger tham the distance between the lower surface 266 of O shape circle 328 and cap 214.
For rolling-ball unit 200 is installed in the opening 350, can at first rolling-ball unit 200 be arranged on the opening 350, and O shape circle 328 is removed.Can make rolling-ball unit cup-like portion 212 move along the mobile rolling-ball unit 200 that is directed downwards shown in the arrow among Figure 10 362 then by the through hole 352 of opening 350.This downward motion lasts till the upper surface 348 of the lower surface 266 contact platforms 112 of rolling-ball unit cap 214.Under this condition, the circular groove 252 of Fig. 4 will place below the lower surface 349 of platform 112 just.Be installed in the groove 252 by below platform 112, O shape circle being slipped over cup-like portion 212 then along direction 364.In case O shape circle is installed in kind of a mode, it will prevent that rolling-ball unit 200 from moving along direction 364, thereby rolling-ball unit 200 is securely locked in place.The edge that should be noted that rolling-ball unit cap 214 can tilt slightly so that article moving on platform 112.
The operation of rolling-ball unit 120 in the sweep 110 of conveyer system 100 among Fig. 1 will be described now.Rolling-ball unit 120 will be described in conjunction with the rolling-ball unit 200 of Fig. 2.Obviously as can be known, the ball 210 of Fig. 2 can move between higher position 332 and lower position 336.Thereby when ball during in higher position 332, sizable part of ball 210 will be stretched out on the upper surface 348 of platform 112.Yet when ball 210 was positioned at lower position 336, ball had only relatively little part to be higher than on the surface 348 of platform 112.In some embodiments, ball 210 is lower than the upper surface 264 of rolling-ball unit cap 214.
The compressed-air actuated feeding mechanism that schematically marks with Reference numeral 370 among Fig. 2 can be connected to the hole 244 in the cup-like portion 212 in a conventional manner.Being connected among Fig. 2 between air supply device 370 and the hole 244 is schematically illustrated by Reference numeral 372.As can be seen, when not supplying pressurized air, because gravity ball 210 will be placed in lower position 336.Yet when the pressurized air at the enough pressure of supply, ball 210 will be pushed to higher position 332.In this higher position, ball 210 is the opening 312 of supporting base 216A among the sealed picture 7-8 effectively, and prevents that pressurized air from losing in a large number from system.
Have been found that as mentioned above when ball 210 was positioned at higher position 332, ball 210 can support the travelling load of conveyer system 100 effectively, for example moved past the article of the sweep 110 of Fig. 1.As can be seen, when support loads in this way, the power that makes progress on the ball 210 is provided by air pressure fully, thereby need not and mechanical contacts such as spring, cylindrical bearing, otherwise may produce the friction of increase, thereby produces heat and wearing and tearing.Therefore, rolling-ball unit 220 is can at high speed articles conveyed and can not produce tangible wearing and tearing or heat.
According to factors such as weight, can select and adjust to be applied among Fig. 1 the air pressure on each rolling-ball unit 120 on the platform 112 such as each article that are transferred.Another standard that is applied to the air pressure of rolling-ball unit 120 is the interval of rolling-ball unit 120 in the platform 112, makes to supply the enough power that makes progress with the article on the surface 48 of support platform 112.Yet having been found that even ball 210 is forced to into lower position 336, the air pressure of supply also will help to reduce the wipe contact between ball 210 and the low supporting base 216B, and therefore reduce to be applied to the friction drag of the travelling load that is transferred.
It should be noted that, if the midway location of ball 210 between higher position 332 and lower position 336, because ball 210 neither contacts also with upper support seat opening 312A and do not contact with lower support seat opening 312B, will can not form sealing in the rolling-ball unit 200.Therefore, in this case, some pressurized airs will be overflowed from ball transfer unit 200.Yet the amount that has been found that the effusion air can be ignored relatively, as long as keep very little tolerance according to foregoing mode between the diameter Y of the diameter X of supporting base opening 300A (Fig. 8) and ball 210 (Fig. 2).Can find further that also the air quite in a small amount of overflowing in this case helps to cool off in an advantageous manner ball transfer unit 200.Oil can be added to pressurized air, thus effusion air lubrication rolling-ball unit 120.
Referring again to Fig. 2, O shape circle 320 is used for reducing and begins ball required compressed-air actuated amount when lower position 336 moves to higher position 332.This realizes by the amount that reduces the air that contacts ball 210 when ball 210 is positioned at lower position 336.
Use together with the curve or the turning part of conveyer system although should be noted that rolling-ball unit 120 described herein, it also can easily be used for the straight line conveying if desired.Can this embodiment be described in more detail about acceleration device 130 below.
Though disclosed herein is compressed-air actuated use, should be noted that the gas (for example nitrogen) of other form can use alternatively.In addition, the fluid of other form (for example liquid such as water) also can use alternatively.As mentioned above, gas can contain oil, oil lubrication ball transfer device 120.
Describe some embodiments of rolling-ball unit 120, will describe other embodiment of rolling-ball unit 120 now.The birds-eye view of the embodiment of rolling-ball unit 380 is shown among Figure 11.The packing ring 384 that has increase except rolling-ball unit 380 enters the rolling-ball unit 380 to prevent chip, and rolling-ball unit 380 is similar to the rolling-ball unit 200 of Fig. 2 and relevant drawings substantially.
The partial cross section that faces of the rolling-ball unit 380 of Figure 11 is illustrated among Figure 12.Should be noted that Figure 12 is similar to Fig. 2 substantially, wherein ball 210 is positioned at lower position 336 and packing ring 384 is included in wherein.In the embodiment of Figure 12, packing ring 384 is clamped between rolling-ball unit cap 214 and the supporting base 216A.As shown in Figure 12, when ball 210 falls into into or is positioned at lower position 336, packing ring 384 contact balls 210.This contact preventing chip enter rolling-ball unit 380 and influence ball 210 and supporting base 216A, 216B between contact.
Should be noted that the rolling-ball unit 380 of Figure 12 has to retrofit with respect to the rolling-ball unit 200 of Fig. 2 in order to hold packing ring 384.For example, in order to hold packing ring 384, the opening 278 in the rolling-ball unit cap 214 is had to bigger.Rolling-ball unit cap 214 also can have the sunk part 390 that size can be held packing ring 384.Sunk part 390 can be used to securely keep packing ring 384 and does not damage packing ring 384.
As mentioned above, packing ring 384 helps to prevent that chip from entering rolling-ball unit 380.When ball 210 falls into in the rolling-ball unit 380, packing ring 384 contact balls 210, this prevents that chip from entering rolling-ball unit 380.When ball 210 rose, packing ring 384 was enough crooked keeping and the contacting of ball 210, but only the rotation of ball 210 was had the adverse effect of minimum.Therefore, packing ring 384 remains on chip the function that does not influence ball 210 outside the rolling-ball unit 380.
Other embodiment of rolling-ball unit comprises the size that changes ball.For example, the most handy bigger ball of some heavier load transmits, and the most handy less ball of lighter load transmits.Supporting base in the rolling-ball unit can change with ccontaining different big or small balls with other parts.
