There are multiple first venthole 17a.Protrusion 18 is formed in the center of the upper surface of the first resistance lid R1.
The outlet of suction channel 12 is connected to logical with first near the suction inlet of fan 7 by the pipeline 20 of serpentine shape
The alternate path 19 that road 14 is connected to.In addition, being provided with electrodynamic type near the outlet of suction channel 12 and the interconnecting piece of pipeline 20
Damper 21.22 be partition wall, and 23 be pressure sensor.24 be operation control section, is responsible for the energization control to heater 10
System, the adjustment of the aperture of damper 21 and the operating of chain 2 control etc..
Then, the structure of operation control section 24 is illustrated based on dry movement.
No matter whether pallet 3 reaches hothouse 5 all and makes motor 8 to operation control section 24 operates and keep wind as shown by arrow A
It recycles in hothouse 5, and is operated in such a way that the detection temperature of temperature sensor 11 is close to set temperature like that.Example
Such as PID control is carried out using the electric power that relay circuit opposite direction heater 10 supplies.Set temperature is that dried object W1 is impregnated with
Solvent drying temperature, be set to 150 DEG C~200 DEG C or so of temperature.
Before pallet 3 reaches hothouse 5, since the first resistance lid R1 sticks on suction channel 12 as shown in Figure 3
Pump orifice 15 around and pump orifice 15 is blocked, therefore be by for the circulating path of the hot wind in hothouse 5
The first venthole 17a of one resistance lid R1 and recycled.The size of multiple first venthole 17a of first resistance lid R1 and
Quantity is adjusted to, and makes to become identical as dried object W1 by the air drag of the first venthole 17a of the first resistance lid R1
Air drag.The air drag is, for example, 500Pa.
Operation control section 24 so that the pressure sensor 23 that the pressure of each suction channel 12 is detected detection pressure
The mode that reduces of mutual difference change the aperture of damper 21, to keep the air capacity flowed in each suction channel 12 solid
It is fixed.
When pallet 3 reaches hothouse 5, operation control section 24 as shown in Figure 4 rises suction channel 12.Firstly,
It is illustrated to the case where maximum quantity is four dried object W1 is mounted in the pallet 3 of arrival.
By by the driving of each suction channel 12 to lifting position, the thus pump orifice 15 of each suction channel 12 and pallet 3
Lower surface abuts and reclines.Rising initial stage and pumping of the first resistance lid R1 being arranged in each suction channel 12 in suction channel 12
Suction pipe road 12 rises together, but since abutting the protrusion 18 of the first resistance lid R1 with dried object W1,
The first all resistance lid R1 overcomes under the action of dried object W1 the active force of compressed spring 13 and is pressed.Exist as a result,
The first gap S1 is formed between suction channel 12 and the first resistance lid R1.The air drag of first gap S1 is than the first resistance lid R1
The first venthole 17a air drag it is small, e.g. 10Pa or so, therefore the hot wind in hothouse 5 does not pass through the first resistance
It covers the first venthole 17a of R1 and is recycled by the first gap S1.At this point, operation control section 24 is still so that each pressure
The mode that the mutual difference of the detection pressure of sensor 23 reduces changes the aperture of damper 21, to make in each suction channel 12
The air capacity of middle flowing is fixed.
When in this state, when operation control section 24 detects that the drying process of four dried object W1 is completed, make to own
Suction channel 12 decline, and make chain 2 operate and pallet 3 is moved out from hothouse 5, next pallet 3 is moved to drying
Room 5.
Above-mentioned explanation but is only disposed on pallet 3 simultaneously to four withering situations of dried object W1
In the case where being in rarefaction state there are three dried object W1 as dried object W1, when the fortune for detecting that pallet 3 arrived
When turning control unit 24 rises suction channel 12, as shown in the right side of Fig. 5, it is mounted with dried object W1's in pallet 3
At dry place, with Fig. 4 the case where in the same manner as form the first gap S1 between suction channel 12 and the first resistance lid R1, it is dry
Hot wind in room 5 is not recycled by the first venthole 17a of the first resistance lid R1 by the first gap S1.
At the dry place for not disposing dried object W1 of pallet 3, as shown in the left side of Fig. 5, even if making to aspirate
Pipeline 12 rises, and the first resistance lid R1 will not overcome the active force of compressed spring 13 and be pressed, therefore with Fig. 3 the case where is same
Recycled by the first venthole 17a of the first resistance lid R1 to sample.
Still changed in a manner of reducing the mutual difference of detection pressure of each pressure sensor 23 at this point, turning control unit 24
The aperture of variable damping device 21, so that the air capacity flowed in each suction channel 12 be made to fix, therefore, can with in pallet 3
The case where there are four the dried object W1 identical time is disposed to be dried.
When operation control section 24 detects that drying process is completed, decline all suction channels 12, then drive chain
Item 2 moves out pallet 3 from hothouse 5.
It should be noted that it is that necessary composition is wanted that damper 21 and operation control section 24 are not to the control of damper 21
Part.Only the pump orifice 15 of suction channel 12 is set to open or block up by the first resistance lid R1 even if not controlling the aperture of damper 21
Plug, also can there are shorten drying time when deviation in the quantity of each withering dried object.
It should be noted that only being avoided by controlling the aperture of damper 21 because of quilt without using the first resistance lid R1
In the extended situation of drying time caused by the deviation of the quantity of dried object, due to the stream of the indoor hot wind of hothouse 5
It is dynamic unstable in a short time, therefore delay is generated until the flowing of hot wind is stablized.Therefore, in order to being placed in pallet 3 and
The each dried object for being moved to hothouse 5 starts to be dried rapidly with hot blast rate appropriate, it is preferred to use the first resistance lid
The combination of R1 and the adjustment based on damper 21.
It should be noted that be illustrated in case where being mounted with four dried object W1 of maximum in pallet 3, but
In the case where disposing the dried object there are three dried object below or five or more in pallet 3, also can similarly into
Row is implemented.
(embodiment 2)
Fig. 6~Fig. 8 shows embodiments of the present invention 2.
In the embodiment 1, the identical situation of the weight of multiple dried object of aeration cylinder-like body is shown, but at this
In embodiment 2, even if also can in the weight of each withering multiple dried object there are in the case where deviation
With and weight deviation is not present the case where identical time be dried.
Fig. 6 shows the major part of the drying device of embodiments of the present invention 2.Other are identical as embodiment 1.
Drying condition in the embodiment 2 are as follows:
The withering situation of dried object of maximum quantity is disposed in pallet；
Placement is less than the withering sparse situation of dried object of maximum quantity in pallet；
The case where there are weight differences between each other of the dried object disposed in pallet.
In pallet 3, the first step portion 6a in addition to being formed with placement dried object W1 is also formed with the second resistance of placement
Cover the second step portion 6b of R2.Second resistance lid R2 is than the first resistance lid R1 path.
(a) of Fig. 7 is shown in the pallet 3 in placement maximum quantity for six dried object, in six mounting position P1
First step portion 6a and second step portion 6b are each formed at~P6.Be mounted at mounting position P1, P3, P5 of pallet 3 by
Dried object.The height of the dried object W2 disposed at mounting position P3 is the dried object disposed at mounting position P1, P5
The half of the height of W1.That is, the air drag of dried object W2 is the half of the air drag of dried object W1.(b) of Fig. 7 shows
The section of the mounting position P1-P3 of pallet 3 out.
Shown in (b) of such as Fig. 7, respectively by the second resistance lid at mounting position P2, P4, the P6 for not disposing dried object
R2 is placed in the state of second step portion 6b, and pallet 3 is moved to hothouse 5.
Before pallet 3 reaches hothouse 5, since the first resistance lid R1 sticks on suction channel 12 as shown in Figure 3
Pump orifice 15 around and pump orifice 15 is blocked, therefore be by for the circulating path of the hot wind in hothouse 5
The first venthole 17a of one resistance lid R1 and recycled.The size of multiple first venthole 17a of first resistance lid R1 and
Quantity is adjusted to, and makes to become air drag identical with dried object W1 by the air drag of the first resistance lid R1.The sky
Atmidometer identical as the air drag of dried object W1 is, for example, 500Pa.
Operation control section 24 so that the pressure sensor 23 that the pressure of each suction channel 12 is detected detection pressure
The mode that reduces of mutual difference change the aperture of damper 21, to keep the air capacity flowed in each suction channel 12 solid
It is fixed.
When pallet 3 reaches hothouse 5, operation control section 24 rises each suction channel 12.Each suction tube risen
The pump orifice 15 in road 12 is abutted with the lower surface of pallet 3 and is reclined.(a), (b), (c) of Fig. 8 be shown respectively with mounting position P1,
The state of the corresponding suction channel 12 of P2, P3.
In the suction channel 12 of mounting position P1 the first resistance lid R1 for being arranged suction channel 12 rising initial stage with
Suction channel 12 rises together, but since abutting protrusion 18 with dried object W1 along with rising, the first all resistances
Power lid R1 overcomes under the action of dried object W1 the active force of compressed spring 13 and is pressed.As a result, suction channel 12 with
The first gap S1 is formed between first resistance lid R1.Air drag of the air drag of first gap S1 than the first resistance lid R1
It is small, e.g. 10Pa or so, therefore the hot wind in hothouse 5 is not passed through by the first venthole 17a of the first resistance lid R1
The first gap S1 is recycled.At this point, operation control section 24 or so that the detection pressure of each pressure sensor 23 it is mutual
Difference reduce mode change the aperture of damper 21, so that the air capacity flowed in each suction channel 12 be made to fix.
The first resistance lid R1 being arranged in the suction channel 12 of mounting position P2 along with suction channel 12 rising
And rise together with suction channel 12, the pump orifice 15 of the suction channel 12 after rising is abutted with the lower surface of pallet 3 and is reclined.
In addition, the protrusion 18 of the first resistance lid R1 is abutted with the second resistance lid R2 for being placed in mounting position P2 by rising.To first
The weight of force ratio the second resistance lid R2 for the compressed spring 13 that resistance lid R1 exerts a force upwards is big, therefore from the first resistance lid
The protrusion 18 of R1 is abutted with the second resistance lid R2 to be started, and along with the rising of suction channel 12, the second resistance lid R2 is from pallet 3
Second step portion 6b is lifted, and forms the second gap S2 between pallet 3 and the second resistance lid R2.Due to the sky of the second gap S2
The air drag of multiple second venthole 17bs of the atmidometer than being formed in the second resistance lid R2 is small, e.g. 10Pa or so, therefore
Hot wind in hothouse 5 does not pass through the second gap S2 by the second venthole 17b of the second resistance lid R2, and then passes through air
Resistance is the first venthole 17a of the first resistance lid R1 of 500Pa to be recycled.At this point, operation control section 24 or so that
The mode that the mutual difference of the detection pressure of each pressure sensor 23 reduces changes the aperture of damper 21, to make in each suction
The air capacity flowed in pipeline 12 is fixed.
The second resistance lid R2 and dried object W2 is mounted at mounting position P3.In the suction channel 12 of mounting position P3
First resistance lid R1 of middle setting rises at the rising initial stage of suction channel 12 with suction channel 12 together, but from along with rising
And abut protrusion 18 with the second resistance lid R2 and start, the first all resistance lid R1 overcomes pressure under the action of dried object W2
The active force of contracting spring 13 and be pressed.The first gap S1 is formed between suction channel 12 and the first resistance lid R1 as a result,.The
The air drag of one gap S1 is smaller than the air drag of the first resistance lid R1, e.g. 10Pa or so.By dried object W2 into
And do not pass through the first venthole 17a of the first resistance lid R1 by the hot wind of the hothouse 5 of the second resistance lid R2, and pass through second
Gap S2 is recycled.At this point, operation control section 24 is still so that the mutual difference of the detection pressure of each pressure sensor 23
Reduced mode changes the aperture of damper 21, so that the air capacity flowed in each suction channel 12 be made to fix.That is, for example existing
In the case that the air drag of dried object W2 is 250Pa, by the way that the air drag of the second resistance lid R2 is set as 250Pa, make
Total air drag becomes 500Pa, so as to be dried under the same conditions with dried object W1.
It should be noted that being only mounted with mounting position P4, P6 and load of the second resistance lid R2 there is no dried object
The case where seated position P2, is identical.In the case where mounting position P5 is mounted with dried object W1, with phase the case where mounting position P1
