Background technology
This kind mobile station rack device is characterised in that the removable stand of operator enters in the passage that forms between adjacent stand and is able to pick and place article from the stand of hope as required, compares with the fixed rack device, and this kind structure can be saved the space.
Self-evident, in this kind mobile station rack device,, will forbid that stand moves by the locking wheel for preventing the people in the passage to be squeezed between stand because of stand moves.Specifically, if the manual stand of shaking will make the chain locking that connects handle and wheel motionless, if the electrodynamic type stand will make the motor locking motionless.
Well imagine, for further guaranteeing safety, one end of farm labourer's part to be supported on the pillar middle part of being located at stand feeder connection side corner sections, usually, this farm labourer's part keeps erecting state along described pillar, simultaneously, and when in people's access passage, make this farm labourer's part tilt to revolve to turn 90 degrees in adjacent stand direction and be the level of state, this farm labourer's part plays top rod (prominent っ か え rod) and guarantees passage width between stand.
Yet, as previously mentioned, both: only with the words of wheel lock, because wheel still can slide on guide rail, form at the stand big between the stand of passage, when bumping because of certain reason with bearing capacity, or when running into violent earthquake, guaranteeing to be difficult to guarantee sufficient safety aspect the passage width.Again, even adopt with farm labourer's part and make a top rod, when earthquake occurrence, in case each stand produces distortion or diagonal, even occurring the front end of farm labourer's part probably touches less than the pillar of described stand or touches and obtain but out of square or the situation of buckling takes place, therefore lower to guaranteeing safe reliability.Moreover, promptly allow to guarantee passage width, but because of the middle part of farm labourer's part at stand is the level of state, so farm labourer's part also causes trouble to evacuation.
Summary of the invention
The present invention can solve these deficiencies at one stroke, be intended to seek to improve the certainty and the safety of operation, it is provided with deformable or mobile horizontal stand with the built state between the upper end of adjacent stand, and corresponding many stands follow the tracks of servo-actuated because of the displacement of moving the passage width cause to each other, and forbid the distortion of this horizontal stand or move when operation.
The mobile station rack device that the present invention relates to is applicable to that a plurality of stands are the mobile station rack device of removable frame along guide rail, forbids that the passage that forms between adjacent any stand is narrow in the width of regulation.It is characterized in that this device is provided with horizontal stand, this support is being provided with the state between the upper end that is scaffolding in adjacent stand and can be out of shape with the passage width that stand moves generation and moving; Also be provided with and when the passage width state consistent, work and forbid the blocking device that described horizontal stand produces distortion or moves with described Rack; And be the latch-release device of action of the device that unlocks.
This kind structure is the configuration of cross-over connection shape at ordinary times because of horizontal stand between adjacent stand, even each stand deforms or diagonal, the front end that also can not produce the sort of farm labourer's part of support before above-mentioned touches the bad phenomenon less than the pillar of adjacent stand, and the effect of this horizontal stand is being guaranteed width of channel as a top rod.Self-evident, produce when mobile because of slip makes stand at guide rail and wheel, also can guarantee width of channel.Therefore, with comparing in the past, guaranteeing to increase substantially reliability aspect the passage width.Further, be arranged on because of horizontal stand between the upper end of stand, can not impact access way so be in operation, played the effect that does not hinder evacuation, in addition, not single right and wrong are often carved, when daily use, also can use as the blocking device of guaranteeing passage width.
After passage forms, blocking device must be worked automatically, the operator need not operate especially for starting blocking device, and best structure is the state formation work readiness for action that will become passage width narrower than aforementioned Rack by mobile stand with the blocking device of latch-release device formation action disarm state.
As simple in structure, realize being easy to specific embodiment, can be exemplified below: horizontal stand is to carry out the connection that can rotate mutually between each end with a pair of link rod element, and the connection that can rotate is mutually carried out with the upper end of adjacent stand respectively in two the other end.Blocking device is by forbidding that these link rod elements rotate the distortion of forbidding described horizontal stand to each other.
This horizontal stand is when passage reaches Rack, and as the linearly each other structure of link rod element, during by existing Fixed width degree stenosis, the link rod element does not rotate desire to each other, therefore exists to hinder the defective that stand moves with passage width.For avoiding this phenomenon really, desirable structure is that the link rod element is＜the word shape each other when passage width is opened to the Rack state.
Be logical parts, the simplified structure of reducing, blocking device preferably has retainer and the elasticity parts of energizing.Retainer is located on side's linkage part, can and the other party linkage part can be being to close the position and can not being that the non-system of closing closes between the position and moves of closing; The elasticity parts of energizing are being to close on the locality retainer to be carried out elasticity and energize.The latch-release device have can will be in described non-system close the position retainer with the fixed parts of prescribed form, utilize the elasticity that the constitutes blocking device parts of energizing, be that purpose is carried out elasticity and energized with retainer to form described prescribed form.
In particular, blocking device has and can protrudingly be embedded on the maintenance body that is installed on side's linkage part and the rotatable braking roll that supports retainer and braking roll is carried out the coil spring that elasticity is energized along protrusion direction as the elasticity parts of energizing, have that will to be raised in by this helical spring expansion force be that the end lateral margin in the other party linkage part closes in the braking roll system of closing the position, with this function that linkage part can not be locked each other with relatively rotating.It is to close parts and be located at the fixed parts that keeps body that the latch-release device has what be located at described braking roll, when this braking roll be positioned at do not forbid non-system that linkage part rotates each other close the position imbed the position time, by the rotation of predetermined angular, it is to close in fixed parts also the projection of this braking roll to be forbidden that parts are closed in described system.Utilize described helical spring torsion, with described braking roll towards being that to close parts and fixed parts be that cooperation is rotated and energized.
The operator forgets latch-release in order effectively to prevent to walk out passage after the end of job, but the latch-release device is preferably made by sagging in the gangway width direction operating mode that forms of the cord section of central authorities slightly.

The specific embodiment
Below, with reference to accompanying drawing one embodiment of the present of invention are described.
The structure of the mobile station rack device 1 that present embodiment relates to as shown in Figure 1, be to have a plurality of stands 2 on many guide rail R that lay in parallel to each other on the ground, by these stands 2 are moved along guide rail R, formed 2 of any stands and the vertically extending passage S of guide rail R.Be to illustrate by built-in direct motor drive in the present embodiment with each stand 2, but also harmless to promote the manual type form that stand itself moves stand.
Be provided with safety gear in the present embodiment, the horizontal stand 3 that it comprises between the upper end that is scaffolding in adjacent stand 2 and can be out of shape or move along with the variation of the passage width of the mobile generation of these stands 2; According to moving of stand 2, when arriving Rack H, passage S starts and to forbid that described horizontal stand 3 distortion come the blocking device 4 of control channel width stenosis; Remove the latch-release device 5 of the effect of this blocking device 4.
Details are as follows in relevant each one of this safety gear.Horizontal stand 3 is made up of a pair of linkage part 31,32 as Fig. 2～shown in Figure 7, and each linkage part the 31, the 32nd is that main body constitutes respectively with channel member 31b, the 32b of top opening.One end 31a of one side's linkage part 31 is roughly discoid, and an end 32a of other party linkage part 32 is little tabular of an end area than an end 31a of side's linkage part 31.One end 31a of one side's linkage part 31 goes up the overlapping end 32a that other party linkage part 32 is being set, the two carries out turnable connection by pin 33, simultaneously, he end 31c, the 32c with each linkage part 31,32 is bound up on the top board 25 of adjacent stand 2 in the mode that can horizontally rotate respectively.Be that main body constitutes with channel member 31b, 32b on these linkage parts 31,32, in order that not only keep lightweight but also obtain full intensity.The space that this channel member 31b, 32b and diapire and two side surround can be used as the shelf space P that preserves distributions such as cable and is used.
The horizontal stand 3 of this kind structure contacts with each other can't form passage S fully the time at adjacent stand, be inside warpage shown in Figure 2 look squarely for vee shape both close-shaped; When passage width is consistent with Rack H, as shown in Figure 3, Figure 4, linkage part 31,32 for angle to each other be greater than close-shaped, inwardly looking squarely of warpage is＜font, promptly opens shape.
Details are as follows about this blocking device 4.Be closed cylinder type below maintenance body 41 is provided with and keep phosphor bodies 411; Be located at the flange part 413 that this keeps phosphor bodies 411 upper ends and becomes one; Be tightened on this upper end that keeps phosphor bodies 411 and with the lid 412 of closure of openings above it.
The diameter of inserting hole 42a and braking roll 42 roughly the same, it runs through the place ahead slightly, side of an end 31a of side's linkage part 31.Specifically, install when horizontal stand 3 is expanded shape as shown in Figure 3, Figure 4 and do not close with the end 32a system of other party linkage part 32, and as shown in Figure 2 horizontal stand 3 be close-shaped or be closed with open between shape the time at least the one part be on the position of closing with an end 32a of other party linkage part 32.
That is to say, during the shape of this blocking device 4 between horizontal stand 3 is close-shaped or closed and opens, braking roll 42 is in the following inhibition that its upper end is subjected to other party linkage part 32, can not the projection the action readiness for action, and when horizontal stand 3 is expanded shape, as shown in Figure 8, braking roll 42 is from top projection and with the lateral margin 32b of an end 32a of other party linkage part 32 and closes, forbids that this other party linkage part 32 forwards close-shaped lock out action state to.
Latch-release device 5 is imbedded the position as Fig. 8～shown in Figure 11 for the braking roll 42 that will constitute blocking device 4 is fixed on, and makes it can not make lock out action, so be provided with the set pin 52 that parts close in the conduct system that is located on the braking roll 42; As this set pin 52 being in the bottom surface 53 of imbedding the fixed parts that location status fixes with braking roll 42; With making this set pin 52 and bottom surface 53 is that the braking roll 42 of closing is rotated and carried out elasticity that elasticity the energizes parts of energizing; Cord section 51 as the operating portion of operating this latch-release device 5.
Details are as follows about each one of this latch-release device 5, and set pin 52 is to be pressed into the cylinder-like part of installation by intersecting vertically at the middle part of above-mentioned braking roll 42 and its with extending.
The effect of bottom surface 53 is the bottom surfaces that are used as from a pair of raised body 53A of the bottom surface projection of described lid 412.The center of 2 corresponding lids 412 of raised body 53A is disposing symmetrically.
The elasticity parts of energizing are held a concurrent post by the coil spring 43 that constitutes blocking device 4.Both, an end of this coil spring 43 had been fixed on the set pin 52, and the other end is fixed on the base plate that keeps body 41, gives braking roll 42 rotational forcees with its torsion.
When spurring this flexible cord 51 downwards and make braking roll 42 imbed the position, coil spring 43 rotates braking roll 42, and set pin 52 is to close with the bottom surface 53 of raised body, in order to prevent braking roll 42 projectioies.On the bottom surface 53 of raised body 53A, be provided with protrudingly and forbid the stopper pin 531 of braking roll 42 because of the torsion inordinate rotation of coil spring 43.
In an embodiment, be provided with and be in the re-setting device 6 of blocking device 4 involutions of latch-release state because of latch-release device 5 to the action readiness for action.
This re-setting device 6 is by the cross bar 61 of the bottom of being located at braking roll 42 and be located at cross bar on the other party linkage part 32 and energize and form with the parts 62 of energizing.
The parts 62 of energizing are to touch described cross bar 61 from the sagging flap of an end 32a of other party linkage part 32, in that this other party linkage part 32 is turned to from expanded shape when close-shaped, and the set pin 52 that makes fixed stop axle 42 is to close to the direction of removing to rotate with the bottom surface 53 of raised body 53A.
Action and method of operation thereof with regard to safety device in the present embodiment is illustrated below.
When 2 of adjacent stands did not form the state of path S as yet, as shown in Figure 2, horizontal stand 3 was close-shaped, blocking device 4 be suppressed at for the upper end of braking roll 42 other party linkage part 32 an end 32a following can not the projection the action readiness for action.Therefore do not forbid moving of these stands 2.
To one the adjacent stand 2 is moved when strengthening passage width to Rack H, horizontal stand 3 becomes expanded shape from this state, and an end 32a of other party linkage part 32 is not in the top position of braking roll 42.Its result, braking roll 42 is because the expansion force of coil spring 43 and projection and be to close mutually with an end 32a lateral margin of other party linkage part 32, make this other party linkage part 32 become the state of the close-shaped direction of banning of turning movement, both Fig. 3, Fig. 8, locking mode of operation shown in Figure 10.In this state, forbid that by blocking device 4 horizontal stand 3 that is out of shape plays a part the top rod, therefore stand 2 is moved and form the passage width stenosis.
After forming passage S like this, when the operator fulfils assignment out in passage S, pulling flexible cord 51, braking roll 42 is positioned at imbeds the position.At this moment, flexible cord 51 hangs down from central authorities near feeder connection, so can prevent effectively that the operator from forgetting to draw the situation of flexible cord 51.By this operation, as Fig. 4, Fig. 9, shown in Figure 11, latch-release device 5 starts, and forms the latch-release state.Both: braking roll 42 is rotated by the torsion of coil spring 43, braking roll 42 set set pins 52 are to close with the bottom surface 53 of raised body mutually, in order to preventing braking roll 42 projectioies, and form linkage part 31,32 and can rotate once more each other, become stand 2 transportable states.
Next, the operator is if will form passage S, and mobile stand 2 during with above-mentioned passage width stenosis 2 of other stands, linkage part 31,32 turns to closer to each other, corresponding with it, the parts 62 of energizing of being located at other party linkage part 32 touch the cross bar 61 of being located at braking roll 42 bottoms, opposite with the torsion of coil spring 43, making braking roll 42 is that the direction of closing is rotated to removing the bottom surface 53 of set pin 52 with raised body 53A.The bottom surface 53 of set pin 52 and raised body 53A is in case releasing system closes, and by the expansion force of coil spring 43, braking roll 42 is just protruding thereupon.Then, with this state, as shown in Figure 6, the upper end of braking roll 42 is subjected to the inhibition of the 32a bottom surface, an end of other party linkage part 32, has only projection slightly, that is to say, is the action readiness for action of above-mentioned blocking device 4.
In the safety gear of the present embodiment of this kind structure horizontal stand 3 always crossbearer between adjacent stand 2, therefore, both made each stand 2 distortion or diagonals, this horizontal stand 3 also can play an effect of top rod really, and guarantees passage width.Self-evident, even producing stand because of sliding, guide rail R and wheel move, also can guarantee passage width.Therefore, at the reliability of guaranteeing to increase substantially aspect the passage width at safety., be configured in because of horizontal stand 3 between the upper end of stand 2 in addition, the turnover that does not influence passage S in service, do not have aspect the barrier evacuation, the outward appearance aspect also can be satisfactory.
Again, consider situation in the past, because operational error, or forgotten the locking wheel, or forgotten farm labourer's part is placed flat-hand position etc., safety gear can't be worked.In the present embodiment, blocking device 4 on the stand 2 that does not form passage S as yet is the action readiness for action at ordinary times, and state moves the width H that stand 2 makes passage S formation regulation thus, even do not do what special operation therebetween, blocking device 4 also will inevitably automatically be worked.Therefore can further improve safety.
The present invention is not limited only to the foregoing description, also various distortion can be arranged.For example, when the present gantries breadth was very long, horizontal stand was not limited only to be located near the feeder connection, also can be at the many places built.Again, horizontal stand made with respect to stand can slide mobile structure, and blocking device made to forbid that horizontal stand slides mobile structure with respect to stand also passable.Also have, the latch-release device also is not limited only to the structure of the foregoing description, as long as it is just passable to meet the form of horizontal stand, also can consider to use electromagnetic type mechanism.In addition, in the foregoing description, when passage broadening during to Rack, blocking device is inevitable automatically to be started, and it is also passable to start blocking device in hand fortune mode, or additional mechanism, makes the user also passable to the selection that blocking device can carry out automatic or manual.
The concrete structure of other each ones is not limited only to the above embodiments, without departing from the spirit and scope of the present invention, can do all distortion.
More than be described in detail the present invention, because of horizontal stand all the time built between adjacent stand, each stand was deformed or diagonal, the front end that the sort of in the past farm labourer's part also can not occur touches the fault less than the pillar of adjacent stand, this horizontal stand plays a part a top rod definitely, is guaranteeing passage width.Self-evident, even, also can guarantee passage width because of the slip of guide rail and wheel causes stand to move.Compare with device in the past, guaranteeing to increase substantially reliability aspect the passage width.Moreover, be located at because of horizontal stand between the upper end of stand, even also do not hinder access way at work, also can rise to there not being the effect that barrier is evacuated.
To make by mobile stand by the blocking device of latch-release device formation action disarm state and make the narrow structure that forms the action readiness for action in described Rack of passage width, because mobile stand, when making passage reach Rack, blocking device is started automatically.That is to say that the operator need not to operate especially for starting blocking device, therefore can avoid the accident that makes blocking device not work and cause owing to reasons such as forgetting operation, make safety be able to further raising.
Horizontal stand is that each end with a pair of linkage part can connect each other rotationally, and the parts that each his end is connect rotationally in the upper end of adjacent stand respectively.Blocking device is by forbidding that these linkage parts rotate the device of forbidding described horizontal stand distortion mutually.These can be realized with simple structure.
In this horizontal stand, when passage reaches Rack, if linkage part is the words of linearity structure each other, at needs when Rack dwindles passage width, linkage part does not rotate each other yet, exists the problem that stand moves that hinders, and when passage width reaches the open configuration consistent with Rack, if linkage part each other＜word shape structure, just can positively avoid the problems referred to above.
Blocking device is provided with the braking roll that can protrudingly bury and support rotationally and this braking roll is carried out the coil spring that elasticity is energized along projection direction on the maintenance body that is loaded on side's linkage part, by being to close the braking roll of projection mutually with the other party linkage part, and the lock function that linkage part can not be rotated is to each other mutually arranged with this helical spring expansion force.The latch-release device has that to be located on the described braking roll be to close parts and be located at fixed parts on the described maintenance body, by with this braking roll in the rotation that predetermined angular is carried out in the position of imbedding of not forbidding that linkage part rotates each other, so that parts close in described system is to close mutually with fixed parts, and forbid this braking roll projection.Utilize described helical spring torsion, it is that cooperation is rotated and energized mutually that described braking roll is closed parts and fixed parts towards described system, like this, can provide commonization of blocking device with the component parts of the device that unlocks, but and simplified structure, cuts down components number.
The latch-release device can prevent from effectively to forget when the operator walks out passage after the end of job that by operating by the sagging flexible cord that is roughly central authorities in the channel amplitude direction thing that unlocks takes place.
Have the shelf space P that the distribution of preserving cable etc. uses in the horizontal stand, on the electrodynamic type stand, special-purpose distribution mechanism is not set also can carries out distribution easily each stand.
