First, with reference to Fig. 1～Fig. 4, the concrete structure of thin plate rolling door 1 is described.Sheet cassette 4, end plate 6a, 6b are installed in the both sides mounting or dismounting that are formed the box body 6 of the tubular of quadrangular section when observing in side freely, thereby form the box chamber of hollow form.Indoor at this box, accommodated end plate 6a, 6b by left and right and carried out in the mode that can be rotated the sheet reeling 5 of the hollow cylindrical that axle props up along left and right directions.And, be formed with the internal communication of the pillar 3 of left and right and allow the peristome 6c of thin plate 2 lifting moving in the rear lower portion of box body 6.
Right-hand end plate 6a is arranged on the root of the motor 7 of cylindrical shape on medial surface by bolt, supports thus facing in sheet reeling 5.The driving body 8 that motor 7 forms the concavo-convex wheel body being arranged on driving shaft 7a engages and sheet reeling 5 is carried out to positive and negative rotation driving with the inner face of sheet reeling 5.
In example shown in the drawings, the end plate 6b of left props up the fulcrum 8b axle of the installing plate 8a with the left part that is arranged on sheet reeling 5 on medial surface, and locking is carried out in the left part of box body 6.Thus, the horizontal earth's axis of sheet reeling 5 is propped up in sheet cassette 4, along with the positive and negative rotation of motor 7 carries out the extraction decline of thin plate 2 and reel to rise access is opened and closed.And the thin plate rolling door 1 of this embodiment, can be by being arranged on the control part (not shown) in control panel 9, select common switching pattern described later and defrosting pattern to carry out the on-off action of thin plate 2.For example can be arranged under the low temperature of-20 ℃ of left and right the access etc. that article are carried out to the equipment of freezing and refrigeration keeping locates.
; control part in control panel 9; by to prior art in be uniformly set the manual operation instruction that the 9a of console switch portion on control panel 9 carries out; and positive rotaring signal and the reverse signal of automatic detection of the test section detecting by body (sensor) 9b based on being arranged on thin plate guide part ll; make motor 7 positive and negative rotations; thus, carry out the thin plate on-off action in switching pattern conventionally.On the other hand, by the mode selector switch 9e that is arranged on the defrosting control part (loop) in control panel 9 is carried out to handover operation, thereby according to the pattern control instruction from common switching pattern to various defrosting patterns shown in Fig. 7, Fig. 8, carry out the defrosting action of the thin plate 2 based on defrosting pattern.And in the time of defrosting pattern, the buzzer 9c that is arranged on the top of pillar 3 by connection carries out reporting of state.And, corresponding to needs, heater 9d is set by the required position of pillar 3, motor 7 etc. in thin plate rolling door 1, can prevent the generation of frost, dewfall.
And, the lower end of thin plate 2 be provided with double as heavy hammer part thin plate 2 towards below load grounding parts 12, this grounding parts 12 drops at thin plate 2 under the closed condition of lowest part, keeps hermetic carrying out ground connection along smooth ground or floor etc. (hereinafter referred to as floor).This grounding parts 12 as shown in Figure 2, by the both ends of turning back of the bag-shaped ground connection thin plate 12b of the weight 12a along laterally in-built iron pipe etc., and is pasted to form before and after the lower end of thin plate 2 under overlapping state.And, in ground connection thin plate 12b, and between weight 12a, clamp the buffer unit 12c that sponge, elastomeric material form, and, between the bottom of weight 12a and ground connection thin plate 12b, form spatial portion.Thus, as shown in the chain-dotted line of Fig. 2, in the time that grounding parts 12 drops to lowest part, can prevent the direct butt in weight 12a and floor, and can make ground connection thin plate 12b along floor closely ground connection keep tightness.
Thin plate guide part 11, as shown in Fig. 2～Fig. 5, forms along the vertical direction groove 13 on the face inwardly of pillar 3, embeds the outer guide 14 that is formed コ word shape cross section in this groove 13, the end inwardly of paired sidewall 14a before and after fixing.And, inner orbit 16 and the top inner orbit 17 being connected with the top of this inner orbit 16 are carried out chimeric and installed in the mode that can install and remove outer guide 14 is interior.In addition, outer guide 14, inner orbit 16 and top inner orbit 17 are formed by the flexible synthetic resin material with abrasion resistance and regulation.
As shown in Figure 4, Figure 5, inner orbit 16, in the time overlooking observation, the left and right sides of the partition wall 19 arranging along the vertical direction in track component, be provided with engaging guide 21 inwardly, this engaging guide 21 engages in the mode that can carry out lifting slip with the guide protrusions 10 being attached on thin plate 2.And, on outer guide 14, form in thin plate direction of extension and there is the flexible inner support portion 22 that is used for installing.
Engaging guide 21 forms by having from the both sides of partition wall 19 the paired guide wall 23 of the outstanding hook-shaped termination portion arranging inwardly. Guide wall 23,23 is formed with the sheet groove 23a between the hook portion that is formed at termination portion, the lifting of thin plate 2 being led, and, between root side and partition wall 19, be formed with and be communicated with sheet groove 23a and accommodate the projecting slot 23b of guide protrusions 10 in the mode that can carry out lifting slip.
Illustrated projecting slot 23b, forms hook portion abreast the groove width of sheet groove 23a and guide protrusions 10.Under the common Installation posture of the inner orbit 16 shown in Fig. 4, thin plate 2 is positioned in guide protrusions 10 under the state in the middle of the left and right of projecting slot 23b of engaging guide 21 with the state being restricted of extracting of side inwardly and carries out lifting slip.
And when thin plate 2 contacts with people during in lifting, high wind etc. and while causing the load that is subject to fore-and-aft direction, the two ends of thin plate 2 are stretched inwardly, guide protrusions 10 is tending towards extracting from sheet groove 23a.Now, be restricted because guide protrusions 10 makes to extract by the hook-type of a pair of guide wall 23 in front and back, therefore, can prevent that thin plate from getting loose and can carry out the lifting guiding of thin plate 2.
According to this structure, the mount pin 26 that has been set with spiral helicine spring 28 is housed under the state in inner support portion 22, can make the termination portion of mount pin 26 outstanding from cotter way 27.Inserting and be located in the installing hole 29 of diapire 14c of outer guide 14 from the termination portion of the outstanding mount pin 26 of this cotter way 27, the detachable retainer 30 of latch etc. being installed with this, is limited excessive slip inwards.
Be set with the mount pin 26 of above-mentioned spring 28, the quantity of the multiple installing holes 29 that wear according to the installation interval that separates regulation on the above-below direction at outer guide 14 is housed in inner support portion 22, each mount pin 26 is inserted to each installing hole 29 of corresponding outer guide 14.
According to this structure, as shown in Figure 4, inner orbit 16 is installed under the state being inserted in outer guide 14, the diapire 14c that is flexibly pressed to outer guide 14 by the elastic force outwardly of each spring 28 is upper, and engaging guide 21 is flexibly stretched thin plate 2 it is supported along thin plate direction of extension outwardly by guide protrusions 10.
The thin plate guide part 11 forming as described above, in the time that thin plate 2 is subject to the load of the direction orthogonal with thin plate face (fore-and-aft direction), as shown in Figure 5, inner orbit 16 is subject to the pulling capacity of direction inwardly by thin plate 2 and guide protrusions 10.Now inner orbit 16 can flexibly slide along direction inwardly by antagonistic spring 28 in outer guide 14, therefore can cushion the power of drawing direction.And, now deflection deformation guide wall 23,23 and partition wall 19 flexibly return, therefore, can prevent the breakage of thin plate guide part 11.
Then, with reference to Fig. 2, Fig. 3, top inner orbit 17 is described.This top inner orbit 17 is connected with the top of inner orbit 16 freely in the interior mounting or dismounting of outer guide 14.And, the upper part integrated of top inner orbit 17 give prominence to the plate retainer 31 that horn shape extends that is being provided with inwardly.This thin plate retainer 31 can be distinguished butts with the retainer 32 of the both sides, top that are arranged on grounding parts 12.By screwing up nut on the bolt connecting before and after the lap of the lower end at above-mentioned thin plate 2 and ground connection thin plate 12b, thereby each retainer 32 is arranged on to the both sides, top of grounding parts 12.
In said structure, thin plate rolling door 1, in common switching pattern, motor 7 being rotated and being controlled and upper limit position that rolled sheet 2 makes grounding parts 12 rise to highest point is set for, the above-mentioned retainer 32 representing with solid line in Fig. 2 from thin plate retainer 31 towards below leave the retainer interval of 20 millimeter position vertical motion is stopped.On the other hand, in the time that attachments such as producing misoperation or frost described later in the time that thin plate 2 is reeled is attached to thin plate 2 surperficial thickly, thin plate 2 can exceedingly be wound up on sheet reeling 5 or make winding diameter become large, crosses sometimes above-mentioned upper limit position and carries out vertical motion.In the case, the situation that thin plate retainer 31 rises to more than butt position thin plate with retainer 32 butts is limited, therefore, and can be by this butt be risen and is limited to prevent that grounding parts 12 is exceedingly wound up in sheet cassette 4.
And the thin plate rolling door 1 of embodiment is provided with controlling organization, be used for carrying out that butt limits rising and while stopping at above-mentioned such thin plate 2, eliminate the overload of motor 7 and the on-off action problem of thin plate 2 and keep interim upper limit position.This keeps the controlling organization of interim upper limit position, in the time that above-mentioned retainer 32 stops thin plate 2 butts with thin plate retainer 31 butts, detect controlling organization or detect controlling organization etc. based on the load of following butt to detect motor load by the rotation based on pulse detection, detect the rotation of motor 7.According to detection signal now, control part stops motor 7, thereafter reversing and thin plate 2 is extracted out declines, and retainer 32 in butt state is stopped and remaining on the interim upper limit position that leaves the above-mentioned thin plate 2 of 20 millimeter from thin plate retainer 31 towards below.
Thus, thin plate rolling door 1 is rolled sheet 2 slightly lenitively, thereby make thin plate 2 can not be fixed on butt stop position with the inadequate attitude that stops, under this state, the interim upper limit position that declines and possess smoothly that can stop and remaining on the next period, maintains the holding state that ensuing decline possesses.
And then, keep the controlling organization of above-mentioned interim upper limit position, when the lower end of grounding parts 12 from the bottom of thin plate retainer 31 or sheet cassette 4 towards below roughly in the more new range of the interim upper limit position of 300 millimeter, when overload appears in motor 7 when thin plate 2 is reeled rising, can avoid its overload to keep the holding state declining.
That is, in the time that thin plate rolling door 1 opens and closes at low temperatures for a long time, at the frost of the Surface Creation of thin plate 2, thickness adheres to towards below in turn from top with increasing, and, on thin plate guide part 11, generate similarly and adhere to frost.Under this state, while making thin plate 2 vertical motion, sheet reeling 5 is because the thickness of thin plate 2 increases because of frost, therefore under winding diameter becomes large state in turn, reels.For this reason, can not reach the setting rotation number (for example, 4,5 turn left the right side) of the sheet reeling 5 of being set by lifting travel amount, for example, even if rotation number is fewer (than it, 4 rotation left and right), thin plate 2 also can be crossed upper limit position and make vertical motion retainer 32 and thin plate retainer 31 butts.
And, can prevent that by this rise limitation grounding parts 12 is involved in sheet cassette 4, on the other hand, motor 7, because positive rotation is hindered thereby motor load increases, becomes rotation halted state.
Therefore, in the time that such state of affairs produces in the more new range of interim upper limit position, thin plate rolling door 1 reverses motor 7 by the renewal control of above-mentioned interim upper limit position, thin plate 2 is extracted out to decline, the lower end of grounding parts 12 is for example roughly being stopped after 20 millimeter in decline, load is removed, can be entered swimmingly next period down maneuver.
In addition, in the time that thin plate rolling door 1 stops thin plate 2 in the more position below new range of interim upper limit position in decline, detect controlling organization etc. by load the rotation of sheet reeling 5 is switched to forward from reversion, make thin plate 2 rise to upper limit position.And, in the time that thin plate 2 stops in rising, be judged as and people or thing butt, make thin plate 2 stop and reporting to the police in its position.
And then, because thin plate rolling door 1 possesses common switching pattern and possesses the defrosting pattern of following detailed description, therefore, in the time that thin plate 2 carries out on-off action during setting-up time, be switched to defrosting pattern from common switching pattern, make to be attached to the automatic defrosting operation that the frost on thin plate 2 automatically falls.
Then, with reference to Fig. 6～Fig. 8 the common switching pattern to thin plate rolling door 1, defrosting pattern with and movement posture describe.First, shown in thin plate rolling door 1 chart as shown in Figure 6, in common switching pattern, make motor 7 forwards by above-mentioned climb command (opening instruction), thereby sheet reeling 5 makes thin plate 2 coiling vertical motions, the thin plate retainer 31 of top inner orbit 17 be about to retainer 32 butts before upper limit position, control the rotation of sheet reeling 5 it is stopped the rotation, grounding parts 12 is stopped and becoming the standby attitude of decline.Then, by decline instruction (closing instruction), motor 7 is reversed, thereby sheet reeling 5 make thin plate 2 extract decline out and become closed condition from upper limit position.
Now, the weight that thin plate 2 is subject to grounding parts 12 declines, and in the time that grounding parts 12 arrives suitable earthing position with respect to floor, sheet reeling 5 is stopped automatically.And, the inner orbit 16 of the thin plate guide part 11 on the pillar 3 about the guide protrusions 10 at the two ends of thin plate 2 is formed in guides, thin plate 2 widths (laterally) are stretched and moving decline of sliding in state that prevents from relaxing, access locking is reached to the standby attitude of rising.In above-mentioned common switching pattern, thin plate rolling door 1 by with motor rotation control mechanism identical in prior art, start speedup gradually at rising initial stage and the decline initial stage of thin plate 2 from low speed, reach the translational speed of regulation.On the contrary, in the prescribed limit of rising end of a period phase and decline end of a period phase, carry out from afore mentioned rules translational speed start little by little to make motor 7 low speed rotation and stop slowly stopping control, thus, thin plate 2 is slowly stopped at upper limit position or lower position.
And in the occasion of pattern that defrosts, the mode selector switch 9e being arranged on control panel 9 by handle switches from above-mentioned common switching pattern, thereby, as shown in Figure 6 to 8, automatically carry out Defrost operation by defrosting pattern.In addition, in each figure, represented using thin plate 2 on carrying out once after on-off action till the time that the pattern that makes to defrost is connected as t1(minute), the setting of this defrosting pattern stand-by time, for example can be with 30 minutes intervals to 1 hour unit, in the time range about 24 hours, freely select to set.
And, the number of times that repeatedly carries out oscilaltion action in the defrosting pattern in 1 cycle is represented with n, this setting range can freely select the number of times of 1～10 left and right to set.
, defrosting pattern, becomes the defrosting pattern holding state shown in same Fig. 7 (b) from the pattern manually or automatically of the common switching pattern as shown in Fig. 6 and Fig. 7 (a).At this, the buzzer 9c that is used for informing defrosting pattern is connected, the defrosting for the first time of the action of time (about the 3 seconds) pattern that defrosts afterwards through setting action is carried out as the 1st defrosting mode as shown in Fig. 7 (c)～Fig. 7 (f).Then, a series of defrosting actions shown in Fig. 7 (c)～Fig. 7 (f) are set as the 2nd defrosting mode, carried out in turn the 2nd～n-1 time action.And then, a series of defrosting actions shown in Fig. 8 (k)～Fig. 8 (o) are set as the 3rd defrosting mode, carry out the n time action.
And, in the time that the automatic defrosting operation of the each pattern based on defrosting pattern is over, buzzer 9c is disconnected, revert to common switching pattern.After the standby setting-up time of the defrosting pattern through setting, again start same defrosting pattern, repeatedly carry out a series of automatic defrosting operations.And, the control panel 9 of thin plate rolling door 1, to each setting of above-mentioned common switching pattern and defrosting pattern and defrosting pattern, except the control part of the built-in by not shown carries out, can also be configured to by the PC being connected with control panel 9 and set.Thus, thin plate rolling door 1 is arranged in the refrigerating equipment of the refrigerator that for example moves in the low temperature of-20 ℃ of left and right etc., can be simply and high efficient and reliable ground the frost being attached on thin plate 2 is removed.
Then, with reference to Fig. 7, the 1st defrosting mode of defrosting pattern is described.Start the thin plate 2 rising by moving for the first time of Fig. 7 (c) from the defrosting pattern holding state shown in this Fig. 7 (b), after the rate of climb with regulation (about 2.5m/s) rose for 0.5 second, as shown in Fig. 7 (d), the defrosting height h1 place in the lifting travel way of thin plate 2 stops vertical motion.Then,, after stopping the time in 0.3 second, start and carry out the down maneuver shown in 0.5 Fig. 7 in second (e).Now in the time rising and down maneuver is carried out with identical speed, same time, make down maneuver distance than vertical motion distance by inertia force, thus, make the extraction quantitative change of thin plate 2 many, as shown in Fig. 7 (f), make strongly ground connection and cross the above-mentioned lower position of common switching pattern and floor collision of grounding parts 12, down maneuver is stopped.
In this 1st defrosting mode, make the thin plate 2 of closed condition rise to defrosting height h1 and stop hastily on the way, the vibration being produced by the waving of the inertia force of ascent direction of thin plate 2 and the tensioning of above-below direction and lax and fore-and-aft direction, deflection etc., carries out the 1st defrosting to the surface of thin plate 2.And thin plate 2 is again subject to vibration along with sharply declining from defrosting height hl and carries out the 2nd defrosting.And then thin plate 2 carries out the 3rd defrosting with the grounding parts powerful butts in 12 floors (collision).
Above-mentioned the 3rd defrosting, the weight 12a of the grounding parts 12 of thin plate 2 is by ground connection thin plate 12b and floor collision.Thus, the bottom of grounding parts 12 and thin plate 2, is subject to the ground connection vibration of vibration based on powerful and large deflection variation, can defrost reliably at the thick frost of this part to firm attachment.
Then, with reference to Fig. 7, Fig. 8, the 2nd defrosting mode of defrosting pattern is described.The state colliding ground connection from the grounding parts 12 shown in above-mentioned Fig. 7 (f) and floor starts, in Fig. 7 (g), carry out the position after the vertical motion in 0.8 second in the rate of climb (about 2.5m/s) with regulation, as shown in Fig. 7 (h), the defrosting height h2 that thin plate 2 rises in lifting travel way stops.Then,, after stopping 0.3 seconds, start the down maneuver of Fig. 8 shown in (i) and declined for 0.5 second.Thus, as shown in Fig. 8 (j), thin plate 2 is anxious to stop, and makes grounding parts 12 not remain on height h3 with ground plate earthing.
In this 2nd defrosting mode, in lifting travel, make vertical motion be configured to the anxious thin plate 2 stopping of defrosting height h2 of the position higher than the 1st time, owing to being subject to the 4th vibration different from above-mentioned the 1st vibration, so, can make the frost not falling when last defrosting is carried out in thin plate 2 surfaces fall on a large scale.And then, when making since then thin plate 2 sharply decline as shown in Fig. 8 (j) and anxious stopping, thereby make grounding parts 12 remain on height h3 and during not with ground plate earthing, and thin plate 2 is subject to the 5th vibration that the stretching, extension stretching tensioning of moment is given because of the inertia of grounding parts 12 down maneuvers.Thus, thin plate 2 can make the frost adhering to peel off to front-rear direction, make it to come off towards below, defrosts with other being used for.And a series of defrostings action based on this 2nd defrosting mode, also can carry out arbitrarily number of times (move for 2～n-1 time) from PC side as required.
Then, with reference to Fig. 8, the 3rd defrosting mode is described.In this Fig. 8 (k), at the thin plate 2 of ungrounded state that makes the grounding parts 12 shown in above-mentioned Fig. 8 (j) in thering is defrosting height h3 with the rate of climb (2.5m/s left and right) of regulation after 0.8 second of rising, as shown in Fig. 8 (1), the defrosting height h4 place in the lifting travel way of thin plate 2 stops vertical motion.In addition, defrosting in the case height h4 is configured to the low clearance than defrosting height h2.Then, after stopping 0.3 seconds, start the down maneuver shown in Fig. 8 (m) and carried out for 0.5 second, thus, make the control (slowly stopping controlling) of grounding parts 12 and floor low speed ground connection, as shown in Fig. 8 (n), make thin plate 2 stop at lower position, make thin plate 2 become closed condition, action 3 patterns are over.
And, as shown in Fig. 8 (o), buzzer 9c is disconnected, revert to common switching pattern.After the following time of setting arbitrarily, again start to carry out same defrosting pattern, carry out a series of automatic defrosting operations.In above-mentioned the 3rd defrosting mode, can control by above-mentioned slowly stopping, so that the down maneuver that the mode that sheet reeling 5 does not carry out high speed reverse rotation starts from defrosting height h4 thin plate 2 is rotated control, make thin plate 2 lentamente with low speed decline while stop at lower position.
Therefore, the thin plate 2 that when sheet reeling 5 is rotated, inertia and the inertia force in the time that great grounding parts 12 declines are suppressed can correctly stop, and makes grounding parts 12 can not produce dislocation from lower position towards lower side.And, due to thin plate 2 low speed because of sheet reeling 5 extract out and the deadweight of grounding parts 12 stretch under the state of stretching, extension towards below move, so, lax, the fold that can become the thin plate 2 to producing in above-mentioned defrosting mode have carried out the closed condition stretching, and, can remain on lower position with contacting under the airtight state of maintenance of floor by grounding parts 12, be transformed into swimmingly common switching pattern.
Then, the use state of the thin plate rolling door 1 forming is as described above described.First, the thin plate rolling door 1 of moving with switching pattern conventionally under above-mentioned low temperature, in the time that on-off action frequently carries out, adhering to also of frost is few, so, can with the common environment of normal temperature under carry out swimmingly in the same manner the switching of thin plate 2.On the other hand, when under the state that is not using defrosting pattern under low temperature environment while carrying out the switching of thin plate 2 for a long time, the frost layer after the frost of the Surface Creation of thin plate 2 can adhere to into.
Carry out in the case the thin plate 2 of opening operation, on the sheet reeling 5 that carries out forward, adhered to and under white state, be wound and make winding diameter become large, can prevent that the retainer 32 of crossing upper limit position is involved in grounding parts 12 with thin plate retainer 31 butts.And, now, by the load now producing is detected, the interim reversion of sheet reeling 5 is stopped, making retainer 31 leave and thin plate is stopped and remaining on interim upper limit position from thin plate retainer 32, towards the decline standby attitude conversion of next period.
And, because thin plate rolling door 1 has the defrosting pattern of the automatic defrosting operation function automatically coming off as the frost that has made to adhere to, so, can according to defrost the accordingly setting of pattern of the use state of the low temperature safedeposit of refrigeration, refrigerating chamber etc., automatically switch towards defrosting pattern the action that defrosts from common switching pattern.Thus, can be laborsaving and energy-conservation, and contribute to the quality managemant to the keeping thing in keeping is in low temperature safedeposit.And, because defrosting action possesses various defrosting patterns, so in the time that thin plate rolling door 1 is arranged in the safedeposit of the refrigerating chamber that moves under above-mentioned low temperature etc., the frost that can make simply efficiently to adhere on thin plate 2 comes off.
; in the case; above-mentioned defrosting pattern in embodiment; no matter the 1st defrosting mode, the 2nd defrosting mode or the 3rd defrosting mode; all need not thin plate 2 is all open; near above in the too high lower position that grounding parts 12 is not left from floor, repeatedly carry out lifting action with the short time at every turn, defrost thereby effectively give vibration.For this reason, can flow out to outside situation to cold air and be suppressed, even and the thin plate rolling door 1 of existing pattern also without carrying out large structural change, just can realize efficiently defrosting by succinct and cheap structure.
And, because each defrosting pattern is except giving vibration, can also in each pattern, combine as the defrosting action of feature and carry out a series of defrosting action, can not there is not action reluctantly in each portion of action, and, can be to adhering to of thin plate 2 white part effectively to defrost on a large scale.
That is, in the 1st defrosting mode, thin plate 2 is declined, make grounding parts 12 and floor collision, give strong vibration to the bottom of grounding parts 12 and thin plate 2, the frost reliably this part being adhered to defrosts.
In the 2nd defrosting mode, owing to suddenly stopping keeping height h3, so that grounding parts 12 not with ground plate earthing, so, inertia when large down maneuver by grounding parts 12, can give to thin plate 2 stretching, extension stretching tensioning or the resilience of moment, and it is sharply vibrated towards upper and lower and fore-and-aft direction, white peel off and come off that therefore, can promote to adhere to defrosts.
In the 3rd defrosting mode, owing to making thin plate 2 carry out down maneuver from defrosting height h4, similarly stop at lower position by slowly stopping controlling with common switching pattern, therefore, can make grounding parts 12 gently carry out ground connection (soft landing) and become suitable closed condition.Therefore,, even if thin plate rolling door 1 is in the case of being arranged in the freezing equipment moving under the low temperature of for example-20 ℃ of left and right, also the block frost of generation being stiffly attached on thin plate 2 can be removed reliably.And, thus, can be swimmingly based on carrying out the vertical motion of thin plate 2 by common switching pattern.
In addition, the Defrost method based on each defrosting pattern, order and combination thereof of the defrosting pattern of embodiment, in the thin plate rolling door 1 shown in thin plate rolling door 1 and Fig. 9 of illustrated example, realize in the situation that not making thin plate 2, each action equipment produce action reluctantly and having defrosted, but for the roller door arrangement of the different equipment of white build environment, different modes, defrosting pattern and the pattern that had better set respectively adaptation defrost.
And above-mentioned Defrost method, except using the thin plate rolling door 1 of the thin plate 2 that possesses illustrated example, can use too for the thin plate rolling door 1 of the other embodiment with the thin plate with core components 2 shown in Fig. 9.
Then, describe with reference to Fig. 9, Figure 10 for the thin plate rolling door 1 of above-mentioned other embodiment.In addition, identical structure and the explanation of effect in laborsaving and above-mentioned embodiment.This thin plate rolling door 1 has been pulled down inner orbit 16 and top inner orbit 17 from the outer guide 14 of the thin plate rolling door 1 of above-mentioned embodiment.And, insert the outer guide 14 of left and right by the two ends of multiple cores 33 that the thin plate 2a with core components same as the prior art is had, thereby can carry out lifting slide-and-guide to core 33, carry out the on-off action of thin plate 2a.
Thus, the thin plate rolling door 1 of Fig. 9 becomes decline standby attitude at above-mentioned upper limit position thin plate 2a being wound on sheet reeling 5.And, when making sheet reeling 5 extract when rotation out, thin plate 2a is extracted out, make core 33a and the next core 33 of upper/lower positions ... the slip that declines in rail groove 14b in turn, becomes full-shut position.And, make each core 33 in outer guide 14, carry out up-slip by the coiling rotation of sheet reeling 5, thin plate 2a is reeled and rise.The core 33 of illustrated example, 33a, with being identically formed as pipe of prior art, by being inserted into, the core installation bag 34 of the core installation site that is formed on thin plate 2 is interior to be installed and supports.And at the two ends of core 33,33a, mounting or dismounting are inserted freely and have been installed and roller 36 is rotated to the earth's axis freely prop up the roller shaft 37 at axle head.
