Pass through said structure, at thin plate 2, drop to lowest part, under the blocking that solid line in Fig. 1 of grounding parts 2b and ground plate earthing represents, above-mentioned forward belt 31 as shown in Figure 4, belt upper end is arranged on to the pulley 8a that just converts above reels to form in the counterclockwise direction the mode of maximum winding diameter, belt middle is led to the pillar 3 of lower rear from the top of the leading block 37a that just converts, belt lower end is linked at the installation portion 36 that stretches out upper limit of movement position and piston rod 34.Thus, the piston rod 34 of the cylinder 11a that just the converting forward belt 31 pulley 8a forward that makes just to convert that stretches when air fed retracting motion, meanwhile, makes sheet reeling 5 forward rolled sheets 2 and makes its rising.
On the other hand, inversion belt 32 under above-mentioned blocking as shown in Figure 5, upper end side with contrary with forward belt 31 towards on form minimum winding diameter mode be wound on reversion with on pulley 8b, from reversion, with the top of leading block 37b, lead to the pillar 3 of lower rear, belt lower end is linked with the head of the piston rod 34 of the lower position of cylinder 11b by installation portion 36 and in reversion.Thus, when the cylinder 11a retracting motion of just converting, sheet reeling 5 forwards, thin plate 2 reeled while rising, on one side stretching out to move to the piston rod 34 that pulley 34 side by side makes to reverse the maximum winding diameter of inversion belt 32 formation with cylinder 11b, the reversion of carrying out forward stretches out upper limit of movement position on one side.
And reversion stretches and makes pulley 8b reversion for reversion inversion belt 32 when the air fed retracting motion with the piston rod 34 of cylinder 11b, meanwhile, sheet reeling 5 is reversed, thin plate 2 extractions and make it be declined to become blocking.Now, the pulley 8a that just converts simultaneously reversing carries out coiling action so that forward belt 31 forms the mode of maximum winding diameter, thereby the piston rod 34 of the cylinder 11a that makes just to convert stretches out the upper limit position that moves to draw direction, so, make it revert to original rising holding state.And, as mentioned above, each opening and closing device 7 setting along the pillar 3 of left and right, the housing 41 that its side is コ word shape during by cross-section covers, by 41 mounting or dismounting of this housing are arranged on the outer wall of pillar 3 freely, thus the structure that can provide the upkeep operation of the adjusting, belt exchange etc. of Belt Length easily to carry out.
Be provided with the thin plate rolling door 1 of above-mentioned opening and closing device 7, there is air control loop described later in Fig. 8, when thin plate 2 locking, control valve according to the climb command of test section 9b or console switch 9a by control panel 9 is supplied to from air supply portion 10 the cylinder 11a that just converts compressed air, and controlling reversion becomes release conditions with cylinder 11b.Thus, as mentioned above, according to lower moving (retracting motion) of the piston rod 34 of the cylinder 11a that just converts, forward belt 31 is stretched and extracted out, by the pulley 8a that just converts, carry out 5 pairs of thin plates 2 of sheet reeling of forward and reel, making it rise to the uppermost position shown in the chain-dotted line H in Fig. 1 becomes full-gear.Now, inversion belt 32 so that the mode of winding diameter maximum to be wound on the reversion that is rotated by sheet reeling 5 upper with pulley 8b, make reversion in release conditions with the piston rod 34 of cylinder 11b towards the piston rod 34 with the cylinder 11a that just converts contrary towards carrying out upper move (stretching out motion).
Thus, opening and closing device 7, when the piston rod 34 of the cylinder 11a that just converts is during in lower position, sheet reeling 5 makes thin plate 2 become complete reeling condition, stops at full-gear rising to the position H going up most shown in Fig. 1.And, meanwhile, the piston rod 34 of cylinder 11b for the reversion that becomes release conditions, when thin plate 2 rises, can not hinder sheet reeling 5 just then driven towards stretching out the direction of motion, not can because of now from dynamic resistance, make the crooked tensioning state that remains on of inversion belt 32.Therefore, reversion is reeled inversion belt 32 to form the winding diameter of ormal weight not there is not lax mode with pulley 8b, then, and when reversion is carried out lower moving (retracting motion) with cylinder 11b, reversion can be not slow with the reversion of pulley 8b, and the closing motion of thin plate 2 becomes smooth and easy.
On the other hand, during thin plate 2 standard-sized sheet (decline holding state), control panel 9 makes compressed air with the cylinder 11b cylinder 11a that supplies with and make just to convert, become the control of release conditions towards reversion by above-mentioned decline instruction.Thus, it is lower moving that reversion carries out piston rod 34 with cylinder 11b, and inversion belt 32 is stretched and extracted out, by reversion, uses pulley 8b sheet reeling 5 is reversed and thin plate 2 is extracted out and made its decline forcibly.Now, the just conversion pulley 8a reversing by sheet reeling 5, piston rod 34 opposings of the cylinder 11a that makes just to convert it carry out drivenly from dynamic resistance towards stretching out the direction of motion, forward belt 31 reeled simultaneously and make its winding diameter become maximum.
And, the forward belt 31 being wound when thin plate 2 declines, by piston rod 34, from dynamic resistance, at the pulley 8a that just converts, keep tensioning state to be wound in unflagging mode, so, then, when the cylinder 11a that just converts carries out down when moving, the forward of the pulley 8a that just converting can be not slow, and the breakdown action of thin plate 2 can be smooth and easy.
And reversion when piston rod 34 arrives and stops at lower position, stops the decline of thin plate 2 with cylinder 11b, as shown in the solid line in Fig. 1, become the blocking of grounding parts 2b and ground plate earthing.
And, illustrated example is wound on the thin plate 2 on sheet reeling 5 like that, when grounding parts 2b from great, decline resistance hour, when declining, while being subject to acceleration, decline, but, now, the situation that is subject to from the cylinder 11a that just converts of dynamic resistance, decrease speed being risen to more than required speed is limited.And, for the cylinder 11a that just converts from dynamic resistance, by the evacuating air pressure in free adjustment cylinder chamber, can regulate simply the decrease speed of thin plate 2.
Like this, with respect to the just conversion pulley 8a and the reversion pulley 8b that are provided with sheet reeling 5, by forward belt 31 and inversion belt 32 are opened and are established with different coiling directions, will be towards arranging alignedly along pillar 3 with cylinder 11b the just conversion cylinder 11a of single-action type air cylinder and reversion, thereby, opening and closing device 7 can be made with succinct and cheap structure.And the tracing ability of the action owing to can improve thin plate 2 and open and close time, so can there is not slow can carrying out swimmingly in the action of each portion.
And, opening and closing device 7, is arranged under the state separating due to the both sides at sheet reeling 5 on the pillar 3 of left and right, therefore in couples, space around of the pillar that can utilize each pillar 3 and can not take the large space that arranges, can have convenience and formation is set simply.And; opening and closing device 7; because the lateral surface along pillar 3 collects formation compactly; the foreign side of its cylinder part and belt portion is installed and removed the housing 41 being arranged on freely on pillar 3 and is covered; therefore; can seek the pressure setting of cylinder part, the length adjustment of belt portion and the protection of the device such as check repairing, upkeep operation can easily carry out.
In addition, the thin plate rolling door 1 shown in this embodiment, the switching stroke of thin plate 2 is 2600 millimeter, the drum diameter of sheet reeling 5 is 216 millimeter.And just converting pulley 8a and reversion are 72 millimeter with the belt winder diameter of pulley 8b, just converting cylinder 11a and reversion are roughly 870 millimeters with the stroke of each piston rod 34 of cylinder 11b.Thus, above-mentioned switching stroke with respect to thin plate 2, by the forward belt 31 of the counteragent in opposite directions based on above-mentioned each piston rod 34 and the winding mechanism of inversion belt 32, opening and closing speed that can be identical with the thin plate rolling door be provided with electro-motor in the past carries out the lifting (switching) of thin plate 2.
Then, the structure of the pith of opening and closing device 7 is described.As shown in Fig. 3～Fig. 5, pulley 8a and reversion pulley 8b are just converting, by forming the winder 43 with the belt width of coiling belt and the pulley depressed part of diameter, and the guide part 44 leading from the left and right to belt of the both sides outstanding setting in the form of annular discs of this winder 43 forms.And just converting leading block 37a and reversion respectively in pulley 8a and the reversion rear lower portion with pulley 8b of just converting, are configured in the symmetric position facing toward above the axle center with each piston rod 34 in opposite directions with leading block 37b.
Thus, just converting leading block 37a and reversion are supported the middle part rotation of forward belt 31 and inversion belt 32 freely with leading block 37b, towards the axle center extended position of each piston rod 34, lead.For this reason just the converting impact of variation of winding diameter of forward belt 31 can not be subject to on-off action with leading block 37b time of leading block 37a and reversion and inversion belt 32, can make forward with cylinder 11a with reverse with each piston 34 of cylinder 11b retract action time smooth and easy the carrying out of action.
And, at the head of each piston rod 34, be provided with the guiding parts 49 that utilizes the mounting structure of installation portion 36 to lead to the knee-action of piston rod 34.This guiding parts 49 consists of the plastic plate of overlooking as square, its central portion is inserted to piston rod 34 and reinstate the fastening installation of nut 46 with mount pad 47 1.Thus, be fixed on guiding parts 49 on piston rod 34 by in-built, and the lateral surface of its periphery and pillar 3 and the medial surface of housing 41 are free to slide, the mobile guide of the above-below direction in the whole stroke of piston rod 34 carries out swimmingly.
; on piston rod 34; especially when sheet reeling 5 being carried out to positive and negative rotation switching; belt by forward belt 31 and inversion belt 32 waves etc., before and after the head that carries out expanding-contracting action applies and the transverse load of left and right directions, still; with respect to this transverse load; guiding parts 49 contacts with the wall sliding of loading direction, and the transverse shifting of piston rod 34 is limited, and makes that expanding-contracting action is smooth and easy to carry out.Therefore, just converting cylinder 11a and reversion can not occur moving smoothly limpingly with cylinder 11b, and, can make the high speed of piston stretching speed become easy.
Then the air control loop with control panel 9 grades, opening and closing device 7 being provided with describes with reference to Fig. 8.This air control loop, is supplied to control panel 9 from air supply portion 10 by air tank 56.And control panel 9 makes it carry out on-off action with connecting just converting cylinder 11a and reversion on valve cell with cylinder 11b in forward and reversion.And, on control panel 9, connect the console switch 9a that sends the on-off action instruction of thin plate 2 by manual operation, and to detecting by body, automatically sending the test section 9b of the explosion-proof pattern of on-off action instruction.
Above-mentioned air tank 56, by the air that makes to supply with from air supply portion 10 as in the past set tankage size and the accumulator valve of regulation, even stop from the air supply of air supply portion 10 sides, the on-off action of thin plate 2 also can carry out several left and right (being 3 times in embodiment).And, as shown in Figure 1 and Figure 2, by axially the approaching and arrange substantially in parallel of air tank 56 and sheet reeling 5, thereby, utilized the space around of reel that sheet reeling 5 is set.
; the thin plate rolling door 1 of illustrated example; at the interior installation frame 57 of dividing before and after a space that is formed on the forward lower part corner between sheet reeling 5 is carried out that arranges of sheet cassette 4, the installation bracket mounting or dismounting air tank 56 by left and right be arranged on freely this installation frame 57 before.And, the below of air tank 56, the cover cover 58 being arranged on freely on sheet cassette 4 by 3 mounting or dismounting of the pillar in left and right covers.
Thus, can suppress to be provided with air tank 56 thin plate rolling door 1 maximization and become succinct structure.And the exchange of the air tank 56 that airtrapping amount is different and accumulate the upkeep operation of the adjusting etc. of pressure, can open cover cover 58 to carry out from the face side of thin plate rolling door 1.In addition, as shown in the chain-dotted line of Fig. 2, air tank 56 can any space in sheet cassette 4 be set the size of regulation for, and, in the situation that be arranged on the outside of sheet cassette 4, also can arrange along the top of sheet cassette 4.
And, in the air control loop in embodiment, the action air pressure of piston rod 34 retracting motions of the cylinder 11a that is used for making just converting, set for higher than being used for making the action air pressure of piston rod 34 retracting motions of cylinder 11b for reversion.Thus, the just conversion cylinder 11a that supplies with pressure-air carries out retracting motion and the forward belt 31 that simultaneously stretches with brute force, the deadweight of the thin plate 2 of opposing in blocking makes thin plate carry out swimmingly vertical motion, and, by the continuation of air, supply with and make the state of the thin plate 2 in opening operation state keep stable lasting.
And reversion by the supply of low-pressure air, is carried out the retracting motion inversion belt 32 that stretches with cylinder 11b on one side, the initial stage resistance of the rotation of opposing sheet reeling 5 is extracted the initial stage of the thin plate 2 in full-gear out to carry out swimmingly and makes thin plate 2 declines.Now, the affix reversion in To deadweight of the thin plate 2 of decline makes sheet reeling 5 reversions by the retract action power of cylinder 11b.And, while forward belt 31 is wound onto the cylinder 11a that makes just to convert on the pulley 8a that just converts, towards stretching out the direction of motion, carry out driven.
That is, the thin plate 2 declining, stretch out motion drag (from dynamic resistance), thereby (closing motion) action that declines under the state that the situation sharply declining because of thin plate deadweight is limited becomes blocking due to what added the cylinder 11a side of just converting.And, reversion is also proceeded after the locking of thin plate 2 with the air supply of cylinder 11b, thereby the blocking of maintenance thin plate 2, is suppressed the generation of the fold of thin plate 2, deflection.In addition, above-mentioned air control loop can align conversion cylinder 11a and reverse from control panel 9 sides and freely regulate setting etc. by the action air pressure of cylinder 11b.Thus, diversified scene and the purposes of thin plate rolling door 1 can be tackled, opening operation and the closing motion speed of thin plate 2 can be regulated simply.
And then, air control loop is provided with reversion breakdown action control loop 9c, this reversion breakdown action control loop 9c in thin plate 2 closing motions ways, be subject to external force R and the abnormal closing motion that becomes halted state constantly, just the converting variation of the air pressure in cylinder 11a of perception, makes thin plate 2 breakdown action that reverses towards just converting cylinder 11a air supply.Thus, when such as butt things such as automobiles (passing through body), from below or side and closing motion, thin plate 2 butts in the way that declines make thin plate be subject to hindering external force (closing motion load) R of closing motion (decline), the half-open position h place of thin plate 2 in the closing motion way of for example Fig. 1 stops declining, then make thin plate 2 towards the full-gear H breakdown action that reverses, therefore, can prevent thin plate 2, pass through the damage of body and the issuable problem along with butt.
That is, when thin plate 2 is subject to external force R and makes to decline while being prevented from, during beginning turning, by reversion, use the retract action of cylinder 11b by reversion, with pulley 8b, to proceed the sheet reeling 5 of reversion, owing to coiling being relaxed thin plate 2 extractions sheet cassette 4 is interior.And reversion is proceeded retracting motion with cylinder 11b, by just convert pulley 8a and forward belt 31 make just the to convert piston rod 34 of cylinder 11a, stretch out motion.For this reason, the air pressure in the cylinder 11a that just converting changes, the low pressure of air pressure while becoming than normal closing motion.Then, the variation of the air pressure in this cylinder 11a that just converting is inverted breakdown action control loop 9c and detects, and cuts off towards reversing with the air supply of cylinder 11b side and carrying out air supply towards the cylinder 11a side of just converting.
Thus, the cylinder 11a that just converting stops the motion of stretching out of piston rod 34, directly makes it carry out retracting motion and makes sheet reeling 5 forwards.And, in above-mentioned sheet cassette 4, in winder, produce the lax thin plate 2 of reeling, owing to carrying out the sheet reeling 5 of forward, lax the tightly wrapping on one side of reeling started to carry out the rising (reversion breakdown action) of thin plate 2 on one side, therefore, from butt thing, leave and stop at full-gear H.Then, after the factor of the external force R by body etc. is removed, by reversion, use the normal retracting motion of cylinder 11b to move, again make thin plate 2 extract out swimmingly and carry out swimmingly normal closing motion.
And, as mentioned above, the reversion breakdown action carrying out when following the abnormal closing motion (decline) of thin plate 2 of external force R is controlled, while utilizing the normal closing motion of the cylinder 11a that just converting and external force R cause abnormal closing motion time the variation of air pressure carry out, therefore, only by clamping in air loop for switching the succinct and cheap structure of valve that pressure detecting switches etc., just can control reliably.And, cylinder 11b and the cylinder 11a that just converting for reversion, owing to using pulley 8b associated with sheet reeling 5 with forward belt 31 with inversion belt 32 and the pulley 8a that just converting by reversion each other, therefore, impact during to the load variations sharply of following external force R to produce, reversion breakdown action has resiliency, can in the positive and negative rotation of sheet reeling 5 and the on-off action of thin plate 2, not occur inadequate situation.
That is, the resiliency by the flexible of inversion belt 32 and forward belt 31 and when reeling and extracting out, makes to follow the generation of external force R in thin plate 2 down maneuvers and mitigations such as impact when the load variations that occurs and reversion breakdown action.Thus, can prevent the damage of thin plate 2 and the distortion of piston rod 34 etc., and, can seek the protection of air control equipment etc.And, the thin plate rolling door 1 with the air actuated type of above-mentioned such opening and closing device forming 7, owing to air being alternately supplied to the cylinder 11a that just converting, with cylinder 11b, make sheet reeling 5 positive and negative rotations with reversion, so, especially compare with air driven roller door arrangement in the past, thin plate 2 in the time of can using cylinder 11b to make Primary closure action by reversion declines and there will not be closing motion slow, promptly carries out.And, by the air supply in each cylinder part 33, regulate, can freely set the opening and closing speed of thin plate 2, go for multiduty air type roller door arrangement.
Be provided with the thin plate rolling door 1 of the opening and closing device 7 forming as described above, under the blocking of the thin plate 2 shown in Fig. 1, by by test section 9b to detect to detect opening operation by body, by or the opening operation operation of console switch 9a start, from air supply portion 10 by air tank 56 and control panel 9 air supply to the cylinder 11a that just converts.Thus, the piston rod 34 of the cylinder 11a that just converting carries out retracting motion by high air pressure, while tractive forward belt 31 is extracted out, makes just to convert pulley 8a and sheet reeling 5 forwards, thin plate 2 opposing deadweights is reeled and rise.
Now, the inversion belt 32 being wound with pulley 34 by carrying out the reversion of forward, while make reversion stretch out motion with the air that piston rod 34 opposings of cylinder 11b are discharged in cylinder upper from dynamic resistance.And, Yi Bian reversion can be rolled tightly the inversion belt 32 in tensioning state to reel from dynamic resistance by above-mentioned on one side with pulley 8b.And the cylinder 11a that just converting, in the lower position of stretching out the piston rod 34 of motion, makes thin plate 2 become full-gear, on one side hold mode become decline standby attitude on one side.
Then, when test section 9b is not when existing by body by detecting by body, or operate by the closing motion of console switch 9a, from air supply portion 10 by air tank 56 and control panel 9 air supply to reversion cylinder 11b.Thus, reversion is carried out retracting motion with the piston rod 34 of cylinder 11b by low air pressure, on one side tractive inversion belt 32 extract out and make reversion reverse with pulley 8b and sheet reeling 5 on one side, make thin plate 2 extraction declines.
When this thin plate 2 declines, be wound on the forward belt 31 of just converting on pulley 8a, the decline power of following the deadweight of thin plate 2 to produce by opposing stretch out motion piston rod 34 from dynamic resistance, under tensioning state, there will not be to be loosely wound on and just convert on pulley 8a, then, the breakdown action of the thin plate 2 that carries out is carried out rapidly.And, reversion use cylinder 11b, in the lower position of having carried out the piston rod 34 of retracting motion, on one side make thin plate 2 become full-shut position and one side hold mode become rising standby attitude.
Like this, opening and closing device 7, air is alternately supplied to the cylinder 11a that just converting makes it carry out expanding-contracting action with reversion with cylinder 11b, and, make just convert cylinder 11a and the reversion of the non-supply side of air in opposite directions towards being reversed when stretching out motion and retracting motion, carry out relevant action with cylinder 11b, thus, can use pulley 8b with reversing by forward belt 31 and just converting pulley 8a and inversion belt 32, make sheet reeling 5 carry out positive and negative rotation, carry out the opening and closing of thin plate 2.Therefore, the opening and closing device 7 of this air driven, utilizes 2 air cylinder to improve the tracing ability of the action while opening and closing, and, the roller door arrangement of succinct and cheap structure can be provided.
And, be provided with the thin plate rolling door 1 of above-mentioned reversion breakdown action control loop 9c, when the thin plate 2 in closing motion way is subject to external force R that the butt by body such as automobile etc. produces, under the state stopping at this at thin plate 2, detect the variation of the air pressure of the cylinder 11a that just converting, according to this variation, to the cylinder 11a air supply of just converting, make thin plate 2 towards the full-gear H breakdown action that automatically reverses.Therefore, not only can prevent thin plate 2, by the damage of body and the problem of following butt to occur, and can continue to make smooth and easy the carrying out of on-off action of thin plate 2 thereafter.And, can seek to utilize just converting cylinder 11a and reversion to make sheet reeling 5 carry out the high speed of action of the opening and closing device 7 of positive and negative rotation with cylinder 11b.
And the thin plate rolling door 1 as the air actuated formula of above-mentioned that formation, can not produce electric spark, and can utilize reliably air cylinder to carry out action control, so, can also be relievedly towards explosion-proof area, arrange and carry out layout change, mobile setting.And then this thin plate rolling door 1, just can arrange simply owing to only carrying out from the air supply portion 10 in explosion-proof area for example the pipe arrangement that air supply uses, so, can omit for making power supply setting, the electrical engineering of electro-motor action.
In addition, the opening and closing device 7 of the thin plate rolling door 1 of embodiment, arranges just convert cylinder 11a and reversion dividually with cylinder 11b with on the left and right sidesing pillar 3 that is arranged on sheet reeling 5 left and right, but is not limited to this, also can as following, form.; can be not just convert cylinder 11a and reversion not be divided right and left with cylinder 11b etc. yet; but two cylinder 11a, 11b are arranged side by side to the side at sheet reeling 5; at a side concentrated setting of the spool shaft of this sheet reeling 5 just converting pulley 8a and reversion pulley 8b, the two by forward belt 31 and inversion belt 32 by correspondence respectively links separately.
In the case, the pillar 3 of left and right is not set on the top of room opening, by making to carry out positive and negative rotation a side of room opening towards the sheet reeling 5 of longitudinal setting along being arranged on horizontal single rolling door guide part 12, thereby, can form simply and can make thin plate 2 opening and closing device 7 of the rolling door of the horizontal open and close type of freely openable to left and right direction.In addition, be provided with the roller door arrangement of opening and closing device 7 of the rolling door of this horizontal open and close type, the thin plate 2 that can replace the tentiform of illustrated example is used the identical rolling door parts that use in the roller door arrangement with horizontal open and close type in the past, for example, can use straw rain cape (Japanese: Mino) formula, corrugated rolling door parts.
And just converting cylinder 11a and reversion utilize single-acting cylinder to carry out rolling door action control with cylinder 11b in embodiment, still, also can utilize the cylinder of many dynamic formulas.In the case, it is many that the selecting scale that the supply of air is controlled becomes, and the expanding-contracting action degree of freedom of piston rod 34 uprises, and therefore, can more freely carry out the action control of the speed of rolling shutter door switching and time etc.
