In addition, interior proceeds posterolateral guidance unit 31ir also can possess the rear side driving motors (drive source) 17 that drives wheel 12r as illustrated in fig. 2, also can be as this motor of Fig. 3～do not possess as shown in Figure 5.Also can determine whether accordingly arranging rear side driving motors 17 with the weight of the article of carrying.Then,, in the situation that interior proceeds posterolateral guidance unit 31ir arranges rear side driving motors 17, configure the inner side wheel 12f of front guidance unit 31if and the wheel 12r of interior proceeds posterolateral guidance unit 31ir also in upright arrangemently.Accordingly, because two drive wheels travel on the same driving line of track, therefore only carry out same action by the driving motors 16,17 that makes model identical, chassis 10 just can not travel reelingly swimmingly along interior side rails 104.
With respect to this, rear side driving motors 17 be not arranged to interior proceeds posterolateral guidance unit 31ir but in the situation that front, outside guidance unit 31of arranges wheel and driving motors, is being necessary follower rail to be layed in the outside entirety of track.In addition, at the rotating part of track, on the running route of the running route of inboard wheel, outboard wheels, due to the distance difference of travelling, therefore need the control unit turning with the rotation of the driving motors in degree of precision control inner side and outside accordingly with the speed of chassis 10.If in the case of can not controlling well the rotation of the wheel of inner side and the wheel in outside, chassis and interior side rails and follower rail collide while travel, likely become and cause the article breakage of carrying, the reason of fault.
As mentioned above, in the case of by the wheel in the wheel of inner side and outside, any one is used as drive wheel, the laying of follower rail is interval to be expanded, and needs the control unit of driving motors.Therefore when, causing cost surging, make system become complicated.
Next action when, chassis 10 being travelled in orbit describes.For convenience of description, the position of the guide wheel of above-below direction (, guide wheel 35oo or guide wheel 35ii) is defined as to primary importance and the second place.At this, primary importance is the position that can cross the guide wheel of guide rail (, follower rail 105 or interior side rails 104).In addition, the second place be across guide rail and with the position of the relative guide wheel of guide wheel (, guide wheel 35oi or guide wheel 35oi) of pairing.The guide wheel of the second place can contact with guide rail.As follows, lifting mechanism 34i, the 34o of each guidance unit 31if, 31ir, 31of, 31or makes guide wheel 35ii, 35oo move to the second place from primary importance in the mode across the guide rail 104,105 that chassis 10 guiding is advanced as regulation.In addition, lifting mechanism 34i, 34o hinder the mode of the guide rail 104,105 that the regulation of chassis 10 advances that guide wheel 35ii, 35oo are moved to primary importance from the second place to cross.
First,, in the time that chassis 10 travels on main line or branch line, the guide wheel 35ii of front, inner side guidance unit 31if and interior proceeds posterolateral guidance unit 31ir declines, and is positioned at primary importance.At the guide wheel 35ii of this position across interior side rails 104 ground and guide wheel 35io subtend.Therefore, the direct of travel of chassis 10 is traveling the laying direction defined of track 101, and chassis 10 travels along interior side rails 104.On the other hand, the guide wheel 35oo of front, outside guidance unit 31of and outer proceeds posterolateral guidance unit 31or is positioned at the second place.
In addition, main line refers to the part of removing overlapping portion 109, branching portion 107, interflow portion 108 on cyclic track 102, and branch line refers to the part of removing branching portion 107, interflow portion 108 on auxiliary swing-around trajectory 103.
Next, as shown in Figure 4, to chassis 10, at the main line middle arrival branching portion 107 that travels, and the situation that former state continues to travel on main line by branching portion 107 describes.First, as shown in Figure 2, chassis 10 divides beginning deasil to travel from figure left side spin transfer part.In the time that chassis 10 enters the overlapping portion 109 of branching portion 107 upstream sides, the coder 91 of front, inner side guidance unit 31if and interior proceeds posterolateral guidance unit 31ir detects the mark (not shown) being arranged on interior side rails 104 ribs successively in branching portion 107 fronts.If be judged to be detected mark instruction " passing through to main line from main line " by the signal from coder 91 by control setup (not shown), the lift motor 74 of lifting mechanism 34o drives, lifter cam 71 half rotations.By lifter cam 71 half rotations, cam projection 76 moves to lower dead point from first dead center, and the lifting frame 72 of guide wheel 35oo declines.In the time that this lifting frame 72 declines, the swing projection 79 of the guide wheel framework 73 of guide wheel 35oo is in the interior movement of lifting groove 80, and this guide wheel framework 73 swings.Therefore, guide wheel 35oo along track width direction laterally guide rail 105 approach and decline, move to the second place.
Have, as shown in Figure 8, the lift motor 74 of lifting mechanism 34i drives again, lifter cam 71 half rotations.By lifter cam 71 half rotations, cam projection 76 moves to first dead center from lower dead point, and the lifting frame 72 of guide wheel 35ii rises.In the time that lifting frame 72 rises, the swing projection 79 of the guide wheel framework 73 of guide wheel 35ii is in the interior movement of lifting groove 80, and guide wheel framework 73 swings.Therefore, guide wheel 35ii leaves and rises from interior side rails 104 along track width direction, moves to primary importance.That is, replace guide wheel 35ii, the 35io of the direct of travel of regulation chassis 10, guide wheel 35oo, 35oi specify the direct of travel of chassis 10 again.Its result is that chassis 10 travels along follower rail 105.
If advance at branching portion 107 chassis 10, inner side guide wheel 33i crosses interior side rails 104.Afterwards, in the time that chassis 10 enters the overlapping portion 109 in branching portion 107 downstreams, the lift motor 74 of lifting mechanism 34i drives, lifter cam 71 half rotations.If lifter cam 71 half rotation, cam projection 76 moves to lower dead point from first dead center, the lifting frame 72 of guide wheel 35ii decline (with reference to Fig. 7).In the time that lifting frame 72 declines, the swing projection 79 of the guide wheel framework 73 of guide wheel 35ii is in the interior movement of lifting groove 80, and guide wheel framework 73 swings.Therefore, guide wheel 35ii along track width direction to the inside guide rail 104 approach and decline, and move to the second place.Therefore, interior side rails 104 is held between guide wheel 35ii and guide wheel 35io again.
Have, the lift motor 74 of outside lifting mechanism 34o drives again, lifter cam 71 half rotations.By lifter cam 71 half rotations, cam projection 76 moves to first dead center from lower dead point, and the lifting frame 72 of guide wheel 35oo rises.In the time that lifting frame 72 rises, the swing projection 79 of the guide wheel framework 73 of guide wheel 35oo is in the interior movement of lifting groove 80, and guide wheel framework 73 swings.Therefore, guide wheel 35oo, moves to primary importance away from also rising along track width direction from follower rail 105.Therefore, finished by the guiding of the chassis 10 of front, outside guidance unit 31of and outer proceeds posterolateral guidance unit 31or effect, travel along interior side rails 104 by the guiding of front, inner side guidance unit 31if and interior proceeds posterolateral guidance unit 31ir.
Next,, as shown in Fig. 5 (b), the situation that chassis 10 is travelled to branch line from main line via branching portion 107 describes.First, when chassis 10 travels on main line, guide wheel 35oo is in primary importance, and guide wheel 35ii is in the second place., chassis 10 travels along interior side rails 104 by the guiding of front, inner side guidance unit 31if and interior proceeds posterolateral guidance unit 31ir.Next,, in the time that chassis 10 enters the overlapping portion 109 of upstream side of branching portion 107, the coder 91 of front, outside guidance unit 31of and outer proceeds posterolateral guidance unit 31or detects the mark (not shown) being arranged on follower rail 105 ribs successively.If be judged to be detected mark instruction " from main line to branch line branch " by the signal from coder 91 by control setup (not shown), guide wheel 35oo and guide wheel 35ii maintain position now.If chassis 10 maintains this state in the time that branching portion 107 advances, the object being held in the guide wheel 33i of inner side becomes auxiliary rotary rail 106 from interior side rails 104.Its result is that chassis 10 advances along auxiliary rotary rail 106 rotation limits, limit.
The situation of next, chassis 10 being travelled from an alignment main line via interflow portion 108 describes.First, the coder 91 of front, outside guidance unit 31of and outer proceeds posterolateral guidance unit 31or detects the mark (not shown) being arranged on branch line successively in interflow portion 108 fronts.If be judged to be detected mark instruction " from an alignment main line interflow " by the signal from coder 91 by control setup (not shown), guide wheel 35oo and guide wheel 35ii maintain position now.Advance in interflow portion 108 if chassis 10 maintains this state, the object being held in the guide wheel 33i of inner side becomes interior side rails 104 from auxiliary rotary rail 106.Its result is that chassis 10 advances along interior side rails 104.
Next, during being travelled on main line, chassis 10 describes by the situation of interflow portion 108.First,, in the time that chassis 10 enters the overlapping portion 109 of interflow portion 108 upstream sides, the coder 91 of front, outside guidance unit 31of and outer proceeds posterolateral guidance unit 31or detects the mark (not shown) being arranged on follower rail 105 ribs successively.If be judged to be detected mark instruction " passing through to main line from main line " by the signal from coder 91 by control setup (not shown), with at branching portion 107 do not advance but the situation step that continues to travel along main line is identical to branch line, guide wheel 35oo declines, move to the second place, and guide wheel 35ii rises to primary importance.Therefore,, during chassis 10 advances along follower rail 105, guide wheel 35ii crosses inner side guide wheel 33i.Afterwards, guide wheel 35ii declines, and moves to the second place.On the other hand, guide wheel 35oo rises to primary importance.
As shown in Figure 9, the trolley carrying system 1 of present embodiment not merely possesses auxiliary swing-around trajectory, can also possess the branch line in various path of the main line branch from being made up of cyclic track 102.For example, branch line can be as the marshalling yard of chassis 10.In addition, the chassis 10 of present embodiment only just can be realized travelling of any direction that advances and retreat by switching the hand of rotation of driving motors 16,17., there is no need to change in order to switch direct of travel the formation of chassis 10 or running rail 101.
In the trolley carrying system 1 of above-mentioned formation, on front, inner side guide housing 32i and front, outside guide housing 32o, be linked with front armite 37f by hinge structure respectively.In addition, interior proceeds posterolateral guide housing 32i and outer proceeds posterolateral guide housing 32o are linked with rear armite 37r by hinge structure respectively.By any optionally lifting in branching portion 107 and interflow portion 108 make guide wheel 35ii and guide wheel 35oo, can optionally carry out chassis 10 the branch of branching portion 107, by and at the interflow of interflow portion 108, pass through.Thus, even the in the situation that of lifting mechanism 34i, 34o et out of order, repair this chassis 10 owing to can only changing, therefore can avoid stopping because repairing makes handling system entirety.
In addition, by using auxiliary swing-around trajectory 103 using cyclic track 102 as shortcut, can improve handling efficiency, and owing to having reduced consumes power, therefore can reduce operating cost.
Front, inner side is waved fulcrum and is had the effect that front, inner side rotates fulcrum concurrently, and front, inner side wheel is arranged at front, inner side guide housing.Interior proceeds posterolateral is waved fulcrum and has concurrently the effect of interior proceeds posterolateral rotation fulcrum, and interior proceeds posterolateral wheel is arranged at interior proceeds posterolateral guide housing.Therefore, the formation of chassis 10 can be simplified, and can reduce costs.
By by wheel 12f, wheel 12r as drive wheel, can by these drive wheel arrays configure.Thus, because two drive wheels travel on identical driving line, even if therefore rotating part is for drive wheel also not special control, chassis 10 does not travel reelingly smoothly along interior side rails 104.Therefore, handling system does not have complexity, does not have cost surging, can be simply to form carrying heavy goods
In addition, in the present embodiment, follower rail 105 is only disposed at overlapping portion 109, branching portion 107 and the interflow portion 108 of running rail 101.But, the situation that is weight at the article that are handled upside down or chassis 10 are in the situations such as the moving velocity of rotating part uprises, also can follower rail 105 be set at the rotating part of main line or branch line, be configured to make load that interior side rails 104 bears laterally guide rail 105 disperse.
In addition, in the above description, guide wheel 35oo only moves to the second place in the situation that there is follower rail 105, is positioned at primary importance in addition in the situation that.But guide wheel 35oo also can be only moves to primary importance in the situation that needs are crossed follower rail 105, is positioned at the second place in addition in the situation that.
Have, in the present embodiment, running rail 101 is made up of cyclic track 102, auxiliary swing-around trajectory 103, interior side rails 104, follower rail 105 and auxiliary rotary rail 106 again.But chassis 10 is not limited at the up equipment of sailing of rail bar., chassis 10 also can possess the wheel that can travel in the planes such as floor as wheel 12f, 12c, 12r.In this case, also can omit the rail bar that forms cyclic track 102 or auxiliary swing-around trajectory 103.Even if omitting under the state of rail bar, chassis 10 also can only travel on running rail 101 by guide rail separately.
The switching of the direct of travel of mark instruction also can manually be carried out by operating personal, also can automatically carry out by control unit.In addition,, in the situation that especially control unit being set, can change the path of travelling to each chassis.
In addition, the present invention is not limited to above-mentioned embodiment, shown in the record of claim, also comprises all distortion in the content that is equal to mutually with the record of claim and claim.
