Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a method and apparatus for manufacturing a vacuum double bottle for an automatic processing section and an outer bottle with a vacuum tip tube used therefor. used.

(Prior art) In the days when bottle processing was done manually, the vacuum tip tube was a side tip type installed at the bottom (or periphery) of the bottle, which was a nuisance and was a nuisance. Installing the tip tube in position requires handling, so it is difficult to install the tip tube in place.

The tip tube is attached to the center of the bottom of the bottle, and the tip tube is attached by simply applying a vacuum tip tube to the outer surface of the bottom of a single outer bottle, and heating and melting the part of the bottle where the tip tube is applied. This is done by drilling a hole and welding the edge of the hole and the tip end of the tip tube (problem to be solved by the invention).A tip tube is placed in the center of the bottom of the bottle (= J-shaped center tip). In this model, the tip tube is attached to the most downwardly protruding part of the bottom of the bottle, which has a downwardly convex curved surface, so the length of the bottle increases by around 231), and the outer case does not protect the safety of the bottle. Including extra space for 3
It gets bigger around 01@. This makes the actual capacity relative to the apparent size considerably smaller. This makes the product unnecessarily bulky, increases material costs, transportation costs, warehouse costs, etc., and makes the product cost relatively high. On the other hand, if the tip tube is installed only by simply touching it to the outer surface of the bottom of the bottle, and the two parts are not in close contact over the entire area where it is applied, heat will be transferred from the local heating part of the bottle to the end of the tip. Conduction occurs only at one point, and before the end of the tip tube can be welded, the locally heated part of the bottle melts and a hole opens, causing the edge of the hole to sag. It takes time before the ends can be welded, and that delay causes various problems at the welded part. Therefore, automatic momentary work may cause welding defects. Therefore, a certain degree of consistency is required between the outer surface of the bottle bottom and the end of the tip tube to be applied. It is preferable to install from the facing direction, which limits the mounting direction of the tip tube, and even if the chip 1 tube is slightly chipped at the end, it may cause poor welding.

The limitation on the direction in which the tip tube is attached is that even if an attempt is made to solve the problem with the automatic processing bottle by using a cytochip type bottle in an automatic processing method, the tip tube should be placed in a direction that is approximately normal to the tip tube attachment part at the bottom of the bottle. As a result, the attached tip tube protrudes beyond the perpendicular line to the circumferential surface of the bottle, not only before it is fused and closed during the vacuuming stage, but also after it is fused and closed. If the vacuum tip tube protrudes from a vertical line with the side circumference of the bottle or a horizontal tangent to the bottom of the bottle, the tip tube is likely to come into contact with another object before the outside surface of the bottle. The tip tube itself is susceptible to concentrated loads, and the attachment of the tip tube to the outer bottle in which it is installed tends to apply concentrated loads to the roots.Furthermore, CJ of a still bottle is likely to cause an impactful external force. For this reason, as mentioned above, the bottle is more likely to break t0 due to its easy contact with other objects, which causes a decrease in yield at the manufacturing stage, and also reduces work efficiency due to the troublesome handling.

Moreover, the vacuum tip tube is +j, lI, l' of the bottle.
1) If the bottle protrudes outward from the perpendicular line with the surface, it will be rotated during bottle processing, and the above problem is especially serious considering that it is often deafened by rollover.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides an automatic vacuum tip pipe in which a vacuum tip pipe is provided on the outer periphery of the outer surface of the bottom part and does not extend out from a line perpendicular to the peripheral surface of the bottle side. It is characterized by a processed vacuum double bottle, and more preferably the dip tube does not protrude from a horizontal tangent to the bottom of the bottle.

Furthermore, in forming an outer bottle with a tip tube in this vacuum double-bottle manufacturing, the vacuum tip tube is applied to one point on the outer periphery of the outer surface of the bottom of the bottle in a direction on or close to the normal line to the one point, and the bottom of the bottle is The part to which the vacuum tip tube is applied is heated and melted to make a hole, and one end of the vacuum tip tube and the hole edge of the hole are melted and integrated, and the melted and integrated part softens while not solidifying. Another feature is that the vacuum tip tube is pushed from the outside to correct it to a vertical position.

Furthermore, the present invention provides an apparatus for forming an outer bottle with a tip tube for manufacturing the vacuum double bottle, including a bottle holding means for holding the bottle with the vacuum tip tube attachment part exposed on the outer surface of the bottom thereof, and a vacuum tip tube holding part. between the extended position where the vacuum tip tube to be held is applied to the vacuum and dip tube attachment section at the bottom of the bottle held by the bottle holding means and the dip tube receiving position which is retreated from the vacuum tip tube and receives the vacuum tip tube. heating means for locally heating the vacuum tip tube attachment part of the bottle held by the bottle holding means from within the bottle; and vacuum tip tube attachment of the bottle held by the bottle holding means. At the same time, blowing means blows through the vacuum tip tube fitting means and the vacuum tip tube held by the blowing means, and the vacuum tip tube, which is melted and integrated with the hole edge of the perforation formed by heating and melting the base bottom, is pushed from one side. and posture correction means for correcting the attachment posture to the bottle peripheral wall.

(Function) A vacuum tip tube that does not protrude from the perpendicular line with the side circumferential surface is difficult to contact with other objects during automatic processing of bottles, and even if the bottle is rotated or rolled over, the outside surface of the bottle does not come into contact with other objects. or easy to be supported and protected. In addition, the outer surface of the bottle comes into contact with other objects because it has some elasticity and tends to come into surface contact, making it difficult to act equilibria.

In addition, pushing the tip tube welded to the bottom of the bottle into a vertical position while the welded part is softened allows the tip tube to be welded in a position that is less likely to create a gap between the tip tube and the bottom of the bottle, which is advantageous for welding. The tip tube should be installed on or near the normal line of the outer surface, and the vacuum tip tube should be installed so that it does not come out of the vertical line with the bottle side circumferential surface when the vacuum tip tube is closed by melting during the vacuuming stage of the double bottle. Easy installation provides orientation.

Furthermore, the device enables automatic processing when forming an outer bottle with a vacuum tip tube, and the perforation caused by heating and melting of the tip tube fitting portion of the bottle can be changed in position and area by blowing through the tip tube. It is done properly, and blowing is done by also using the tip 7 pipe fitting means.

(Example) FIG. 1 shows an example of an automatically processed vacuum double bottle for a thermos bottle according to the present invention. To explain this, as shown in the figure, the vacuum tip pipe 2 provided on the outer periphery of the bottom outer surface of the double vacuum bottle 1 is connected to the vertical line a to the side circumferential surface of the bottle 1 and the bottom surface of the bottle 1. It is formed vertically so that it does not extend beyond both horizontal tangents.

This makes it difficult for the tip tube 2 to come into contact with other objects.

Such a vacuum double bottle 1 is made by combining and welding an inner bottle la and an outer bottle lb, which are individually molded as shown in FIG. This is obtained by suctioning and removing the air between them to form a vacuum heat insulating space 3, and then cutting and closing the chip tube 2.

Now, the procedure for forming this vacuum 2 ml bottle will be briefly described, including the installation of the tip tube 2, which is particularly adopted in the present invention.
As shown in FIG. 2, the inner bottle 1a is formed by cutting out the auxiliary edge 4 with a cooling cutter 5 or the like from an inner bottle material 1al which is formed with an auxiliary edge 4 for mouth shaping. On the other hand, the outer bottle 1b has a tip tube 2 attached to the outer bottle material 1b2 formed with an auxiliary edge 6 for mouth shaping. ? ff to make the outer bottle material 1bl, and this outer bottle material lb
When the welded portion of the tip tube 2 attached to the l is in a softened state, it is pushed with a butcher 7 or the like to correct it to the vertical J-6 posture, while the auxiliary edge 6 is cut off with a cooling cutter 8 or the like. These inner bottle 1.1 and outer bottle 1 are formed by
Formation of the vacuum double bottle 1 by fitting and integrating with b is performed as follows. A spacer pad 9 between the inner bottle 1a and the bottle 1b is attached to the bottom outer surface of the inner bottle 1a, and the outer bottle 1b, which is divided into two parts by a cooling cutter 10 or the like in the middle of the body, is placed on this spacer pad 9. Thereafter, the two halves of the outer bottle 1b are welded, and the mouths of the inner bottle 1a and the outer bottle 1b are welded together. This mouth welded portion is shaped by the mold fitting of the shaping mold 1). Then, the inner bottle 1a is passed through the tip tube 2.
The air between the bottle 1b and the bottle 1b is suctioned away to form a heat B empty space 3, and the tip tube 2 is fused and closed while being pulled up and down, thereby completing the formation of the vacuum double bottle.

Next, a specific example of a procedure for attaching a tip tube in forming the outer bottle lb with a tip tube according to the present invention is shown in FIGS. 3 to 6.
As shown in the figure.

The bottle to which the tip tube 2 is attached is an outer bottle material 1bl with an auxiliary rim 6, and is in the form of a so-called narrow-mouth bottle with a large body diameter and a small diameter. The tip tube 2 connects the outer bottle material lbl to a point near the outer circumference of the bottom of the outer bottle material lbl.
The axis of the rod-shaped burner 13 inserted into the interior toward the one point is applied. This direction is the outer bottle material 1.
As shown in Fig. 3, it is angled at an angle α with respect to the normal n erected on the tip tube 2 abutment part on the outer surface of the bottom of the bl, and the end of the tip tube 2 that has been simply cut into pieces and the outer bottle material 1bl are There is only point contact with the outer surface of the bottom part on the inside, and a gap S is created that opens outward (FIG. 3 (bl)).

The outer bottle material 1bl has the burner 1 inserted therein.
The burner 13 is held such that the axis of the burner 13 faces vertically.
The axis of the outer bottle material 1bl is slanted by an angle β with respect to the vertical axis of the bottle. In this posture, the outer bottle material 1bl is rotated together with the tip tube 2 around the axis of the burner 13 while the vacuum tip tube 2 is applied to the bottom outer circumference from the axial direction of the burner 13, and the burner 13 and the outer bottle material are rotated together. It is preheated by a plurality of burners 14 placed in fixed positions around the bottom of the 1 bl.

After this preheating, the outer bottle material 1bl is rotated around the axis of the burner 13 as shown in FIG. 4, the burner 13 is brought close to the bottom of the outer bottle material 1bl, and the vacuum tip tube 2 is applied. Locally heat the area.

When the tip tube 2 abutting part of the outer bottle material 1bl becomes softened before melting due to this local heating, the tip tube 2 is pushed into the bottom of the bottle holder several times as shown in Fig. 5, and as shown in Fig. 5 fbl. As seen in the figure, the tip tube 2 is attached to the end of the bottle L.
The bottle 1 is in close contact with the bottom of the bottle 1, and the entire area of the applied end receives the heat from the local heating part of the bottle 1. From this stage, heating by the burner 14 is stopped.

Furthermore, the local heating by the burner 13 continues, and the tip tube 2 abutting part and the tip tube 2 abutting end of the bottle 1 reach the f6 molten state or a state close to it when almost opened, and in that state, the 1000-knob tube 2 is passed through. Blow is performed on the local heating area. As a result of this blowing, the tip tube 2 abutment part of the outer bottle material 1bl is blown out at its center, as shown in FIG. 6fbl, and the hole 15 is opened.

The diameter of the hole edge of the hole 15 increases as the melting progresses, and when it reaches the diameter of the abutting end of the tip tube 2, the abutting end of the tip tube 2 is also in a molten state or a state close to it, and remains as it is. 1. Alternatively, the hole edge of the hole 15 and the -L end edge of the tip tube 2 are melted and integrated after a short period of time. While this melted and integrated portion is softening, the tip tube 2 is pushed by the pusher 1) as shown in FIG. This attitude is parallel to the axis of the outer bottle material 1bl, and is oriented vertically when the bottle is in the normal position.

After correcting the posture of the tip tube 2, as shown in FIG. Completed with posture correction.

Immediately after installing tip tube 2, burner 13 and burner 1
4 is ignited again, and the tip tube 2 attachment part and the entire bottom of the bottle 1 are later roasted to remove thermal distortion (FIG. 8).

An example of a device for attaching the vacuum tip pipe 2 is shown in FIG. 9 and below. As seen in FIG. 9, on the outer periphery of the turntable 20 which is driven to rotate intermittently,
The bottles 1 are held at equal positions corresponding to the intermittent rotation pitch by bottle holding means 21 as shown in FIG. 10, and the held outer bottle material 1bl is
Each bottle holding means 21 is sequentially and intermittently advanced to a common stop position.

The bottle holding means 21 receives and holds the outer bottle material 1bl in the diagonal positions shown in FIGS. The axis of the burner 13, which is directed toward the tip tube 2 abutment part of the bottle material 1bl, is on the same vertical axis as the axis of the tip tube 2. In addition, the outer bottle material 1bl
A well-known spring force is used to hold it, but its illustration and explanation will be omitted.

The rotation of the outer bottle material 1bl about the axes of the burner 13 and the tip tube 2 is achieved by transmitting the rotating shaft 22 to a driven pulley 24 attached to its lower end with a belt (FIG. 12).

The bottle holding means 21 is combined with a tip tube applying means 30 as shown in FIG. 12, and is intermittently moved together with the bottle holding means 21 by the turntable 20. The tip front applying means 30 is connected to the bottle holding means 21
The elevator shaft 31 has an elevator shaft 31 vertically extending vertically through the rotating shaft 22, and a tip tube holder 32 attached to the protruding end of the elevator shaft 31 toward the rotating shaft 22-A. By fitting the vertical groove 33 of itself with the pin 34 of the rotating shaft 22F,
The annular groove 35 on the outer periphery of the lower end is rotatable as a unit, and the vertical movement range, especially the downward movement position, with respect to the bottle holding means 21 is restricted.
By elastic engagement with the click stopper 36 held on the rotation shaft 22 side, the tip tube 2 received in the tip tube holder 32 is elastically locked at a height position where it is applied to a predetermined position of the outer bottle material 1bl. It has become.

The annular groove 35 has a slight play in the vertical direction with respect to the click stopper 36, and allows the lifting shaft 31 to be raised by about 3 cm from the tip tube abutment height position, and is placed at the bottom of the outer bottle material 1bl. Place the applied tip tube 2 on the outer bottle material 1.
This allows it to be pushed into the bottom of the bl. In addition, a passage 37 is formed in the lifting shaft 31 and is used for dropping the broken tip tube.This passage 37 is always kept half open, and is fully opened manually or automatically as necessary. A slide shutter 38 is provided to ensure that the objects fall.

The stop positions due to the intermittent movement of the bottle holding means 21 and the tip tube applying means 30 are from the first stop position S1 to the 16th stop position S16 shown in FIG. 9, and can be designed in various ways depending on the number of steps and processing method. be done.

At the first stop position S1, the tip tube holder 32 is in the lower movement position and receives the insertion of the vacuum tip tube 2, but the lifting shaft 3
By upward movement by a cylinder or the like of a push-up member 39 (FIG. 13) located opposite to the lower end driven flange 31a of No. 1, the tip tube can be pushed up through the flange 31a to the tip tube application position. Next second stop position S2
Then, the bottle holding means 21 receives the outer bottle material 1bl,
A predetermined portion of the outer bottle material 1bl is brought into contact with the tip tube 2.

Further, at the final stop position 1516, the outer bottle material 1bl, which has undergone the tip tube attachment process, is taken out from the bottle holding means 21. For these operations, each stop position S1
, S2, S16, is the rotating shaft 22 of the bottle holding means 2I.
Times against! 2 drive is stopped 1-.

Third stop! A large number of gas supply connection ports 50 are provided around the outside from the stop position S3 to the fifteenth stop position S15, and the burner 14 for heating adjustment to the bottom of the outer bottle material 1bl is arranged, except in specific cases. At the same time, the bottle holding means 21 is rotated.

Also, from the 41st +h position S4 to the 13th stop F position S13
A burner 13, which is inserted into the outer bottle material 1bl held by the holding means 21 and moved intermittently up to a predetermined position, is provided at each stop position up to and connected to the elevating means 5I using an air cylinder or the like. Each time the material 1bl advances and stops, it is inserted and removed before the outer bottle material 1bl starts to be moved to the next stop +h position, and the tip tube 2 at the bottom of the outer bottle material 1bl is inserted. This allows local heating to be performed without intermittent movement of the outer bottle material 1bl.

The height of the burner 13, which performs preheating from the fourth stop position WS4 to the seventh stop position S7, is set so that heating is performed from a position where the tip of the flame is appropriately separated from the bottom of the row bottle material 1bl. On the other hand, from the 8th (+h position F?s8 to the 10th stop l-, position SIO), the bottom of the outer bottle material 1bl is locally sintered and heated, and the resulting perforation occurs, and the hole edge of the hole 15 and the tip tube 2 The burner 13 for melting and combining the
The height is set so that the tip of the flame heats the local heating portion of the outer bottle material 1bl.

At the ninth stop position S9, where the tip tube 2 abutting part of the outer bottle material 1bl reaches a molten state or a state close to it by the local baking heating, there is a slight push on the tip tube 2 part side shown in FIG. 14. 52 is the flange 31 of the lifting shaft 31
The lifting shaft 31 is slightly pushed up by the operation of a cylinder or the like, and the outer bottle material 1b is
The tip tube 2 that is applied to the outer bottle material 1bl is pushed into the bottom of the outer bottle material 1bl, thereby reducing the gap S between the tip tube 2 and the part of the outer bottle material 1bl that it is applied to. is certain to be resolved.

At the next tenth stop position 510, a blow shaft 53 as shown in FIG. 15 is provided facing the lower end of the lifting shaft 31, and is moved upward by a cylinder or the like and connected to the lower end of the lifting shaft 31. The abutting portion of the locally heated and melted tip tube 2 of the outer bottle material 1bl is blown through the lifting shaft 31, the chi-knob tube holder 32, and the tip tube 2, and a hole is made by blowing.

1) 7-tei! L rank? 7S 1) includes Figures 10 and 1.
) As seen in the figure, a bifurcated pusher 54 for the tip tube 2 is provided so as to face the tip tube posture regulation guide 55 on the bottle holding means 21, and is positioned at the stop position WI.
The tip tube 2, which has reached Sll and is welded to the outer bottle material 1bl on the bottle holding means 21, is pushed against the guide 55 by the operation of a cylinder or the like while the welded part is in a softened state. Correct the posture, that is, the vertical posture with the bottle in the upright position.

During this posture correction, there is a tendency for the thickness of the /8 contact portion on the side where the tip tube 2 is pushed to become considerably large.

However, in reality, at the time of correcting the posture, the welded part of the tip tube 2 is slightly stretched due to its own weight, and as it stretches, it is bent to correct the posture, so there is no need to worry about the above, and if necessary, the welded part of the tip tube 2 It is sufficient to provide a time lag for the tube to stretch by a predetermined amount. If having this time lag is not desirable in terms of work efficiency, a means for forcibly stretching the tip tube 2 by a predetermined amount may be provided.

The burner 13 installed in this 1st) r-tei JL position gs1)
is connected to an air supply source in a timely manner, and the outer bottle material 1b is
The edge of the hole 15 formed by the hole 15 and the end of the tip tube 2-F are brought into contact with each other by air cooling as shown in FIG. . Further, at this stop position S1), a push-down roller 56 as shown in FIG.
is moved downward to pull the tip tube holder 32 downward from the tip tube 2 attached to the bottom of the outer bottle material 1bl, so as not to interfere with the posture correction of the tip tube 2.

At the 12th and 13th stop F positions S12.13, the burner 13.14 performs the rear blowing as shown in FIG. I am making sure that the roasting is done. 1 bl of outer bottle material with heat distortion removed by these post-burning processes
is removed from the bottle holding means 21 manually or automatically at the 16th stop position S16.

Note that 57 indicates a hand-held operation box, and 58 indicates a control panel. In addition, oxygen is forcibly supplied to the heating by the burner 13 to help burn the fuel gas in the outer bottle material 1blO. Fuel gas and oxygen are also supplied to the burner 13 through the connection port 50.

Furthermore, the direction of rotation of the outer bottle material 1bl must be kept constant. For example, at the first) stop position Sll, the rotating shaft 3
A stopper 60 is attached to the positioning portion 59 provided on the outer periphery of the lower end of the
is applied to stop the bottle holding means 21 in a predetermined direction.

(Effects of the Invention) According to the present invention, a vacuum 2 m bottle is provided with a tip tube on the outer periphery of the bottom outer surface thereof so as not to come out from a line perpendicular to the side circumferential surface of the bottle itself, and is automatically processed. Even if the upper bottle is rotated or overturned, the tip tube, which is susceptible to intensive external force, is prevented from coming into contact with other objects, and the bottle itself remains elastic on its sides and bottom under various handling conditions. By coming into contact with other objects in a state of surface contact, it becomes difficult to damage itself and the vacuum double bottle during manufacture, handling, and use. This makes various handling easier and helps automate and streamline work.

In addition, since the outer bottle with the tip tube is used to correct the vertical posture by pushing the anally welded tip tube when the welded part is in a softened state, the vacuum double bottle with the tip tube Weld the tip to a point on the bottom of the bottle that satisfies the conditions in the above table in an advantageous direction that does not leave a gap large enough to cause defective welding or other problems, and after welding, vacuum the tip tube. Since the orientation that makes it easy to obtain the conditions for a heavy bottle can be obtained without any problem in welding, the vacuum double bottle can be obtained without any problem.

Furthermore, the apparatus of the present invention is capable of automatically forming the outer bottle for the vacuum double bottle, and in particular, while applying the tip tube, the tip tube applying part of the bottle that is being heated and melted is formed. Blowing can be suitably accomplished by one tip tube application means and through the tip tube.
