BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for continuously manufacturing a thermos on a mat made of inorganic fiber such as glass fiber, and more particularly, to a method for automatically separating a thermos and a mandrel wound on a mandrel (hereinafter referred to as decentering). .

Conventional decentering methods are disclosed in Japanese Unexamined Patent Publication No. 48-28328, in which one decentering apparatus is installed at a decentering position to perform decentering by intermittent movement of a conveyor. As disclosed, it is roughly divided into the method of decentering by continuous motion of a conveyor.

Although the method disclosed in Japanese Unexamined Patent Publication No. 48-28328 has advantages in that the structure of the decentering machine is relatively simple and the equipment is inexpensive, the drawing speed is increased to increase the speed of one cycle of the decentering to cope with the increase in production capacity. The lower end of the thermos receives the compression pressure and the entire pressure under the pressure is weakened, causing a quality defect.

The method disclosed in Japanese Patent Application No. 53-30374 has the advantage of improving work efficiency without damaging the quality of the thermos because de-centering is performed during continuous movement, but the structure of the de-core machine is relatively complicated, equipment cost is high, and maintenance cost is high. There is this.

In view of the fact that the above-described conventional de-centering method does not deteriorate economically and efficiently without impairing the quality of the thermos, the present invention provides two de-centering mechanisms in the de-centering position and alternately de-intercalates by intermittent movement. It is an object of the present invention to increase the yield of the inorganic fiber thermal insulation container by providing a method of de-coreting economically and with high efficiency without damaging the quality by a severe method.

In order to solve the above object, the invention of claim 1 supports the mandrel, which is formed and cured in the mandrel, with a thermos-coated mandrel, which is wound on the mandrel, so as to be pulled upward by an intermittent moving conveyor, and continuously sent to a decentered position. Two de-centering devices installed above the de-centering position send the mandrel with the thermos to the mandrel grip arm of the preceding de-centering device every time the conveying conveyor stops, and activates the thermo-seal separating member. Return the separating mandrel holding the gripper to the conveying conveyor, and then wait for the mandrel state with the thermos at the time of stopping the conveying conveyor, and at the same time by the time of sending the next thermos with the mandrel Two sequential steps to return the thermos separating member to its original position It has the structure of performing with a decentering device.

In addition, the invention of claim 2 supports the mandrel wound with the inorganic fiber insulation container with the V-shaped attachment member opened upward of the conveying conveyor, and simultaneously faces each mandrel grip arm of the two decentralizing devices to the moving direction of the conveying conveyor. And forward and backward in both forward and backward directions toward the V-shaped attachment member in the decentered position, and the axis of the retracted direction of each mandrel grip arm is positioned within the open angle of the V-shaped attachment member.

In order to clarify the features of the operation of the inventions of Claims 1 and 2, the process of the desealing method using the conventional desealing device A shown in FIG. 4 will be described.

In FIG. 4, the mandrel C with a heat insulation container in which the heat insulation container B made of an inorganic fiber is wound is placed in the decentering position X just under the decentering device A by the conveying conveyor D intermittently moving. And stops while being placed on the V-shaped attachment member (E).

The intermittent movement cycle of the conveying conveyor (D) stops only during the decentering period (T1) as indicated by the solid line (G) in FIG. In order to move (E) to the decentering position X, it has a cycle which moves between the moving periods T2 and stops again.

Therefore, as shown in FIG. 4, when using one decentering device A, the mandrel C from which the insulating tube B is separated remains in the decentering device A. The process of returning C) to the conveyance conveyor D side is needed.

For this reason, within the time of the decentering action period T1 subjected to the decentering action, as indicated by the solid line H in FIG. 5, the decentering position X by the mandrel grip arm F of the decentering device A is shown. The holding stroke (a), the rising stroke (b) of the mandrel (C) with a thermos (C), the drawing stroke (c) of the thermos (B), and the mandrel (C) from which the thermos (B) were separated are conveyed by the conveyor (D). Five strokes, the descent stroke (d) of the mandrel grip arm (F) and the mandrel (C) gripping release stroke (e), are to be carried out.

In addition, the return stroke (f) in which the drawing member, which has been drawn before the completion of the drawing stroke (c) of the insulating container (B), returns to its original position, has the insulating tube attached mandrel (C) at the next position in the decentering position (E). Of course, it is good to be completed by the time of losing.

In the conventional decentering operation, the holding stroke (a) is 1 second, the rising stroke 1 second, the drawing stroke (c) is 2.5 seconds, the rising stroke (d) is 1 second, the breaking stroke (e) is also 1 second. The return stroke f requires 2.5 seconds.

Therefore, the decentralizing period T1 subjected to the decentralizing action is about 6.5 seconds, the moving period T2 is 2.1 seconds, and the total time of the decentralizing period T1 and the moving period T2 is about 8.6 seconds.

As a means of shortening the decentering time and improving the production efficiency, it is not only intended to shorten each stroke of gripping, raising, lowering, and releasing the gripping, but the maximum factor is a shortening of the stroke stroke. to be. However, the increase in the drawing speed exerts a sudden compressive force on the end of the thermos and crushes at the end, resulting in a deterioration in quality, so that it is not possible to improve the decentering efficiency. If it is.

On the other hand, the invention of claim 1 moves the mandrel holding mandrel to the mandrel grip arm of the preceding decentering device every time the conveying conveyor is stopped, and the mandrel holding arm of the next decentering device immediately grips the mandrel holding arm of the next decentering device. Return to the conveying conveyor and wait for the mandrel with the thermos to be delivered at the next stop of the conveying conveyor. In case of two de-centering devices, the conveying conveyor indicated by the solid line (I) in FIG. The same administration is carried out.

That is, during the stopping time TS of the conveying conveyor, as shown by the solid line J of FIG. 5, the holding stroke a1 and the rising stroke b1 are performed by the mandrel holding of the second decentering device, and then the first stroke is performed. The decentralizing device enters the drawing stroke (c1) but at the same time as the ascending stroke, the falling stroke (d2) of the mandrel holding arm (d2) and the holding of the mandrel, which hold the separating mandrel of the second decentering device, as indicated by the solid line (K) The stroke e2 is carried out, and the mandrel grip arm of the second decentering device is brought into the holding state of the mandrel with the heat insulating container at the position.

Since the decentering action by the first decentering device is performed irrespective of the movement of the conveying conveyor, the conveying conveyor is operated only for a period TM at the same time as the completion of the gripping release movement e2, and the desulting mandrel with the thermos attached to the next position is removed. Move to position

Only the stroke stroke (a1), the upstroke (b1), the upstroke (d2), and the freed stroke (e2) are carried out during the suspension period TS. The stopping period of the conveying conveyor is about 4 seconds.

The time required for moving the conveying conveyor is independent of the number of de-centering units. When the de-centering unit is calculated from one unit, the period TM is about 2.1 seconds, but the shortening of this time also reduces the production efficiency. It is important in that respect.

In the present invention, when two de-centering apparatuses are used, the total period of the stop period TS and the period TM is sufficient to be about 6.2 seconds.

In the case of using two de-centering devices according to the invention of claim 1, the downstroke d1 for gripping release of the separating mandrel of the first de-centering device is performed immediately after the ascending stroke b2 of the second de-centering device. The drawing stroke (c1) of the one decentering device is sufficient if it is carried out until the completion of the ascending stroke (B2) of the second decentering device, and can have sufficient time allowance, and several times of time when one decentering device is used. If the defecation in the inside is sufficient, it is possible to quickly release without damaging the thermos. As apparent from FIG. 5, the number of decentering times in the unit time increases as a result of the shortening of the stopping period TS of the conveying conveyor, and the decentering efficiency is improved.

According to the invention of claim 2, the mandrel grip arms of the two de-centering apparatuses face each other in order to face the V-shaped attachment member of the de-centering position supporting the mandrel of the conveying conveyor. Of the mandrel which is retracted and nevertheless has the same direction as the mandrel phage arm and no interference with the mandrel phage arm and the V-type attachment member because the axis of the retraction direction is located within the open angle of the V-type attachment member. The movement and desensitization of the mandrel to the conveyance conveyor are also performed.
