Description
The present invention relates to a kind ofly by inorganic fibre fabric, for example mineral wool or analog are made continuously a kind of method of heat-preservation cylinder, relate in particular to a kind of depoling method that the fuse that is tied with heat-preservation cylinder on it is separated from the heat-preservation cylinder of carrying automatically.
Conventional depoling method roughly is divided into following two types: a kind of is the method that is disclosed in the Japanese patent examination communique clear 48-28328 number, one of them fuse separator is located at the depoling position, so that finish the depoling operation by moving the intermittence of conveyer; Another kind is that to be disclosed in Japanese patent examination communique clear.Method in 53-30374 number, wherein the depoling operation is to finish by moving continuously of conveyer.
The advantage that preceding a kind of method is had is that the structure of depoling device is quite simple and its equipment is cheap; But it exists shortcoming to be qualitatively, in order to improve production capacity, if in the time of must improving the speed from the heat-preservation cylinder depoling, then to reduce circulation timei taking at interval, be applied to nocuously on the end of heat-preservation cylinder then greatly with unexpected draw pressure, this part is depressed and damages the deliquescing inevitably of the whole heat-preservation cylinder of result.
On the contrary, the back advantage that has of a kind of method is, finishes because depoling operates in the process that moves continuously, and promptly conveyer does not stop, so high efficiency can not reduce the quality of heat-preservation cylinder; But its shortcoming is the structure more complicated of depoling device, thereby demanding maintenance cost.
In view of current methods can not be under the situation that does not reduce the heat-preservation cylinder quality economical and finish the depoling operation effectively, the objective of the invention is to propose a kind of method, be provided with in this method and utilized two depoling devices, so that utilize two depoling devices alternately to isolate fuse by intermittently moving from heat-preservation cylinder a depoling position.
The method energy that the present invention proposes is economical and take out fuse efficiently from heat-preservation cylinder, can't reduce its quality, has improved the production capacity of unit interval inorganic heat insulating fiber tube thus.
In order to obtain above-mentioned and some other purpose, method of the present invention has utilized two to be arranged on a depoling device above the depoling position and to finish the following step continuously: each is twined and the fuse that solidifies that is shaped is sent to the depoling position one by one continuously thereon by the inorganic heat insulating fiber tube, so that stop at the there by a conveyer that moves intermittence, fixing in one way by conveyer simultaneously, fuse can upwards be mentioned; When each conveyer stopped, one of the front of two depoling devices of starting was grabbed the core arm by means of it and is mentioned a fuse that has heat-preservation cylinder, starts a heat-preservation cylinder separation member then; Make back one of two depoling devices will grab the fuse of having thrown off that the core arm catches by it at once and be put back on the conveyer, a back depoling device is promptly prepared can mention the fuse that another has heat-preservation cylinder when conveyer stops next time; And the heat-preservation cylinder separation member of previous depoling device is got back to its initial position at previous depoling device next time before mentioning the fuse that has heat-preservation cylinder.
In the method for the invention, inorganic heat insulating fiber tube winding fuse thereon is by the V-type fixture support of the upward opening on the conveyer, wherein, two depoling devices grab separately the core arm successively on the depoling position with respect to the moving direction of conveyer, from forward and the direction of stepping back towards/leave V-type anchor clamps forward/backward, and each axis of grabbing the core arm on the direction that moves forward and backward is positioned at the opening angle of V-type anchor clamps.
Feature of the present invention describes with reference to the depoling method of the single conventional depoling device A of the use shown in preferred embodiment, accompanying drawing and Fig. 4, wherein:
Fig. 1 is the method schematic diagram that the inorganic heat insulating fiber tube is made in explanation;
Fig. 2 is the front schematic view of depoling device;
Fig. 3 is the schematic right side view of device shown in Figure 2;
Fig. 4 is the front schematic view of an example of conventional depoling device;
Fig. 5 is explanation under the situation of using a conveyer and a single depoling device and use workflow diagram under the situation of a conveyer and two depoling devices.
In Fig. 4, the conveyer D that fuse C who is twining inorganic heat insulating fiber tube B on it is moved by a batch (-type) is transported to the depoling position X that is sitting at below the depoling device A, stops on this position then and is placed on the V-type anchor clamps E.
The batch (-type) of conveyer D moves circulation and is represented by the solid line G among Fig. 5, wherein, conveyer D only stops at the time interval T1 of depoling operation, mobile then a period of time interval T 2, so that have the V-type anchor clamps E of the fuse (treating the fuse of depoling) that has heat-preservation cylinder to be transported to depoling position X next its upper support, stop once more at this position conveyer.
As shown in Figure 4, using under the situation of a depoling device A,, therefore, before next depoling is operated, must have one fuse C is put back into step on the conveyer D because the fuse C that separates from heat-preservation cylinder B still stays on the depoling device A.
Therefore, shown in the solid line H among Fig. 5, need to carry out five steps in time T 1, these five steps comprise: step a, grab core arm F at depoling position X by of depoling device A and catch the fuse that has heat-preservation cylinder; Step b, E mentions fuse C from the V-type anchor clamps; Step C extracts heat-preservation cylinder B from fuse C; Steps d, core arm F is grabbed in reduction turns back on the conveyer D fuse C that sloughs heat-preservation cylinder B, promptly is put back on the original V-type anchor clamps E; And step e, unclamp and catch fuse C.
As shown in Figure 5, before next fuse C is transported to depoling position X, time enough completing steps f be arranged, promptly pull-out piece makes pull-out piece get back to its initial position after having finished in step c and having extracted operation.
In above-mentioned conventional depoling operation, grab core step a, lifting step b, extract step c, the steps d that descends, unclamp step e and return the time that step f requires separately and be respectively 1 second, 1 second, 2.5 seconds, 1 second, 1 second and 2.5 seconds.
Therefore, the time interval T1 that is used for the depoling operation is about 6.5 seconds, and traveling time interval T 2 requires 2.1 seconds approximately, and the summation of time T 1 and T2 is about 8.6 seconds.
Thereby enhance productivity in order to shorten the depoling time interval, require certainly to shorten the time interval of grabbing core step, lifting step, decline step and unclamping each step in the step.
The biggest factor is to shorten the time interval that is used to extract step.Yet if improve the speed of extracting operation, a unexpected pressure acts on an end of heat-preservation cylinder nocuously, and this part is damaged, and reduces the quality of product thus.Therefore, it is impossible improving its depoling efficient for the single depoling device of routine A.
On the contrary, according to the present invention, when conveyer stops, a fuse that has heat-preservation cylinder on it is mentioned by means of the core arm of grabbing that is used for the operation of heat-preservation cylinder separation member in one of the front of two depoling devices, and in two depoling devices back one will be put back on the conveyer by another fuse deviate from that the core arm catches of grabbing of a back depoling device at once.And the core arm of grabbing of a back depoling device is got ready mention the fuse that another has heat-preservation cylinder when next time being stopped of conveyer.Therefore, using under the situation of two depoling devices, as shown in Figure 5, in the intermittence of conveyer moving process (representing) by the solid line I finish next procedure.
That is to say that in the dwell time interval T S of conveyer, shown in the solid line J among Fig. 5, the first depoling device is grabbed the core arm by means of it and grabbed core step a1 and lifting step b1, enters then and extracts step c1.On the other hand, in dwell time interval T S, the second depoling device catches the grabbing of fuse of having thrown off to begin to descend steps d 2 when the core arm is finished lifting step b1 on first device with it, then, unclamp the step e2 of next fuse, the core arm of grabbing of second depoling device is in one and can catches another to have the position of the fuse of heat-preservation cylinder at any time.
Because the carrying out of the depoling of first depoling device operation is irrelevant with moving of conveyer, unclamping after step e2 finishes, conveyer is driven a period of time interval T M, so that make the next fuse that has heat-preservation cylinder on it enter the depoling position.
The step of carrying out at dwell time interval T S includes only grabs core step a1, lifting step b1, decline steps d 2 and unclamp step e2.Because aforesaid each step required for 1 second, so the dwell time of conveyer is only required about 4 seconds.
The mobile required time interval of conveyer has no relation with the number of depoling device.According to above-mentioned the situation of using a depoling device, time interval TM is about 2.1 seconds as calculated.In order to enhance productivity, it also is important shortening this time interval.
According to the present invention, using under the situation of two depoling devices dwell time interval T S and time interval TM total and about 6.2 seconds.
Using according to the present invention under the situation of two depoling devices, because after the lifting step 62 of the second depoling device, the first depoling device has been deviate from the decline steps d 1 before the step e1 of unclamping of fuse immediately, and what had before the lifting step b2 of the second depoling device finishes that time enough finishes the first depoling device extracts step C1.Therefore, extracting step C1 can have time enough, compares with the situation of using a depoling device, and fuse can be separated in time several seconds.Thus, fuse can deviate to make heat-preservation cylinder not to be damaged quickly.
As shown in Figure 5, the dwell time interval T S of conveyer is shortened, and has increased the number of times of depoling operation in the unit interval thus, and the efficient of depoling has been improved.
According to the present invention, each of two the depoling devices in depoling position grab the core arm with respect to conveyer towards with leave be placed on conveyer upper support fuse the V-type anchor clamps from upstream and downstream position forward/backward, and the forward/backward axis of grabbing the core arm is positioned at the opening angle of V-type anchor clamps, so that can catch the fuse that is tied with heat-preservation cylinder on it and make the fuse of from heat-preservation cylinder, having deviate from can turn back on the conveyer, this structure is not only being grabbed not interference between the core arm, and grabs between core arm and the V-type anchor clamps also noiseless at each.
Fig. 1 is that the diagrammatic sketch that the present invention makes inorganic heat insulating fiber tube method is implemented in explanation.The inorfil that provides by raw fibre feedway 1, for example glass layer 2 passes through a winding mechanism 3 on fuse, outside one, enter curing oven 5 then through guiding mechanism 4, make binding agent pass through curing oven 5 curing moldings, be transported to the depoling position by conveyer 6 then, utilize a depoling device R that heat-preservation cylinder and fuse are separated from each other in this position.Heat-preservation cylinder and fuse after separating, fuse is sent into winding mechanism 3 once more, so that repeat identical circulation.On the other hand, the heat-preservation cylinder of deviating from from fuse is delivered to verge cutter S successively, and longitudinal cut machine T and marking press U are to obtain heat-preservation cylinder finished product 11.
In said method, conveyer 6 moves off and on, makes to support the depoling position of anchor clamps below preset time just in time stops at depoling device R that is tied with the fuse of inorganic heat insulating fiber tube on it.
Fig. 2 and 3 is schematic diagrames that expression realizes equipment of the present invention, and wherein, V-type anchor clamps 8 and 9 are placed on the conveyer 6, and conveyer is pressed the direction shown in the arrow L and moved off and on.
The inorganic heat insulating fiber tube twine thereon fuse 10 with its relative two end supports on anchor clamps 8 and 9.When fuse 10 was transported to depoling position X, 6 of conveyers stopped a period of time interval T S.
The first depoling device 12 and the second depoling device 13 just in time are arranged on above the depoling position.Depoling device 12 and 13 is respectively arranged with in the same plane on the plane parallel with conveyer 6 directions of advance perpendicular to grabs core arm 14 and 15, make grab core arm 14 and 15 can be respectively by the direction forward/backward shown in double-headed arrow M and the N.
In an illustrated embodiment, grab core arm 14 forward with respect to the direction of advance (shown in arrow L) of conveyer 6, make grab core arm 14 can towards with leave V-type anchor clamps 8 and move back and forth.On the other hand, grab core arm 15 backwards with respect to the aforementioned direction (shown in arrow L) of conveyer 6, make grab core arm 15 can towards with leave V-type anchor clamps 8 and move back and forth.
Each that moves by direction shown in arrow M and the N direction grabs the axes O of core arm 14 and 15 and the intersecting angle θ 2 between the P should be less than the opening angle θ 1 of each V-type anchor clamps 8 and 9.Therefore, axes O and P are set in place in the opening angle θ 1 of each V-type anchor clamps 8 at X place, depoling position and 9.
As shown in Figure 3, each in the first and second depoling devices all has a fuse separation member 17 that moves back and forth along a guide rod 16 that is parallel to the fuse supporting surface that is limited by V-type anchor clamps 8 and 9 by direction shown in the double-headed arrow Q.The fuse separating plate 18 of this fuse separation member 17 can be reduced to be resisted against by grab that core arm 14 (15) is caught and the fuse 10 that promotes on an end face 19 of heat-preservation cylinder 11 on, and move to, thereby heat-preservation cylinder 11 is removed from fuse 10 by the position shown in the chain-dotted line 20.After this fuse separating plate 18 turns back to the position shown in the solid line among Fig. 3.
The fuse of deviating from from heat-preservation cylinder 11 10 is got back to again on V-type anchor clamps 8 and 9 by the decline of grabbing core arm 14 (15).
Method of the present invention is to utilize the first and second depoling devices 12 and 13 and in conjunction with moving realization the intermittence of conveyer 6, has carried out description in conjunction with Fig. 5 above.
That is to say, in Fig. 2, the core arm 15 of grabbing of the second depoling device 13 is to be positioned at raised position when catching the fuse 10A that removes heat-preservation cylinder 11, and when conveyer 6 stopped the next one being had the fuse 10B that waits to remove heat-preservation cylinder 11 and bring depoling position X into, the core arm 14 of grabbing of the first depoling device 12 was caught the fuse 10B that has heat-preservation cylinder 11.To grab core arm 14 then promotes.
Then, the core arm 15 of grabbing of the second depoling device 13 descends, so that the fuse 10A that will separate brings among the V-type anchor clamps 8A, then, grabs that core arm 15 unclamps fuse 10A and prepares to catch the next one to have the fuse 10C of heat-preservation cylinder on that position.
Conveyer 6 moves always before the fuse 10C that has heat-preservation cylinder has occupied depoling position X.
The core arm 14 of grabbing of the first depoling device 12 is raised and enters the depoling step, makes fuse separation member 17 move to the position shown in the chain-dotted line 20 among Fig. 3, and heat-preservation cylinder 11 is taken off from fuse 10B.
When the fuse 10C that has heat-preservation cylinder occupied depoling position X, the core arm 15 of grabbing of the second depoling device 13 was caught fuse 10C and lifting at once.
Before the lifting step of grabbing core arm 15 is finished, take off the step of heat-preservation cylinder 11 by the first depoling device 12 and finish, the fuse 10B that has deviate from catches by grabbing core arm 14.Finish the lifting while of grabbing core arm 15, grab core arm 14 and descend, the fuse 10B that has deviate from is being brought among the V-type anchor clamps 8A, unclamping the fuse 10B that has deviate from and rest on that position.
When taking off after step finishes of heat-preservation cylinder 11, the fuse separation member 17 of the first depoling device 12 enters and returns step.
Afterwards, conveyer 6 is moving always before the fuse 10D that the next one has a heat-preservation cylinder occupies depoling position X.
Before the fuse 10D that has heat-preservation cylinder occupies depoling position X, finish the first depoling device 12 fuse separation member 17 return step.Then, the first depoling device 12 enters the depoling step again and repeats aforesaid operations.
In each above-mentioned step, each that moves by direction shown in double-headed arrow M and the N grabbed the axes O of core arm 14 and 15 and the opening angle θ 1 that P is positioned at V-type anchor clamps 8 and 9, thereby when fuse mention/when descending, V-type anchor clamps 8 and 9 can not disturb fuse fully or grab core arm 14 and 15.
According to the present invention, the depoling operation is alternately carried out by two depoling devices, and before a back depoling step began, previous depoling step was finished.Therefore, eliminated the restriction that the depoling step must be finished in the conventional equipment in the dwell time interval of conveyer, and there is no need to increase the speed of extracting that is used to extract heat-preservation cylinder for improving depoling efficient.Therefore, the present invention has improved the efficient of depoling can't damage heat-preservation cylinder, but also has improved the production capacity of inorganic heat insulating fiber tube.
In addition, according to the present invention, the V-type anchor clamps will never disturb fuse and depoling device, to realize an operation of depoling stably.
