BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a closed container manufacturing apparatus for manufacturing a closed container by fixing a metal lid plate to an open end of a bottomed cylindrical metal container by welding. The present invention relates to a closed container manufacturing system in which a closed container manufacturing device and an airtightness inspection device are combined.

2. Description of the Related Art As a conventional closed container manufacturing apparatus, an upper electrode sheath provided so as to be able to move up and down a required vertical movement distance, a plurality of lower electrode sheaths arranged on a circular movable base, and a lower electrode sheath are hermetically sealed. A component input machine for inputting the components of the mold container, a welding machine for applying a welding current between the upper electrode sheath and the lower electrode sheath to resistance-weld the components of the closed container, and A collecting machine for taking out from the electrode sheath and a collecting container for storing the closed container are provided.
[0003] The operation of the closed container manufacturing apparatus constructed as described above will be described. The circular movable base repeatedly rotates and stops, and at a predetermined position, the closed container is placed in the lower electrode sheath by a component feeder. A metal container and a lid plate, which are parts, are put in. The lower electrode sheath in which all the parts are put in stops at a position where the axis center coincides with the upper electrode sheath. Next, the upper electrode sheath descends and contacts the lower electrode sheath, and the upper welding electrode of the welding machine descends and contacts the upper electrode sheath. After that, a welding current is passed between the upper welding electrode and the lower welding electrode of the welding machine sandwiching the upper electrode sheath and the lower electrode sheath, and the lid plate is hermetically welded to the opening end of the metal container to hermetically seal. Manufacture containers. The manufactured sealed container is taken out from the lower electrode sheath by the collecting machine at the take-out point, and collected in the collecting container.
[0004]
At present, an airtight inspection is performed to determine whether or not the manufactured hermetically sealed container is securely sealed and to prevent the hermetically sealed airtight container from being shipped. The cause of the poor airtightness of the closed container may be a problem of a manufacturing apparatus and a problem of a component of the closed container. The main problem of the manufacturing apparatus is poor contact due to non-uniform contact pressure due to poor adjustment of the welding surface of the electrode sheath or wear in the combination of the upper electrode sheath and any of the lower electrode sheaths. As a result, welding of the closed container becomes uneven, and a very small pinhole or the like is generated, resulting in poor airtightness.
In a conventional closed container manufacturing apparatus, when an airtight inspection detects a poor airtightness in the closed container, the entire apparatus is stopped and the cause of the poor airtightness of the closed container is a problem of the electrode sheath. Investigate whether the problem is due to a problem with the components of the closed container or if it is a problem with the electrode sheath, adjust immediately if it is a problem with the components of the closed container, and review the supply components if the problem is with the components of the closed container. It was necessary to take measures such as taking measures. When the cause of poor airtightness is the problem of the lower electrode sheath, it is rare that the problem occurs simultaneously in multiple lower electrode sheaths, and it often occurs in one lower electrode sheath among the installed ones. It is. However, since it is not possible to identify which lower electrode sheath is a problem by simple inspection such as visual inspection, it is necessary to temporarily stop the entire manufacturing apparatus and perform maintenance work such as inspection and adjustment of all lower electrode sheaths. There is. Until these operations are completed, the production must be stopped for a long time, which not only affects the production plan but also increases the manufacturing cost, which is a major problem.
Accordingly, there has been a demand for a closed container manufacturing apparatus capable of identifying the problematic lower electrode sheath and avoiding a situation in which production is stopped for a long time, and shortening the time required for maintenance of the manufacturing apparatus.
[0007]
Therefore, in the closed container manufacturing apparatus of the present invention, the upper electrode sheath provided so as to be able to move up and down a required vertical movement distance and the center of rotation of the circular movable base which repeats rotation and stop are provided. A plurality of lower electrode sheaths arranged on the same circumference, a component feeding machine for feeding components constituting a closed container into the lower electrode sheath, and a welding current flowing between the upper electrode sheath and the lower electrode sheath. A welding apparatus having a welding machine for hermetically sealing the components of the closed container, a collecting machine for removing the manufactured closed container from the lower electrode sheath, and a collecting container for storing the closed container And, in a closed container manufacturing apparatus consisting of a collecting device having a flow path for moving the closed container taken out by the collecting device to the collecting container, the same number of the collecting containers as the lower electrode sheath is provided, and each lower electrode sheath is provided. Manufactured It is characterized in that the hermetic vessel can be recovered in a separate collection vessel. With this, it is possible to distinguish which closed container is manufactured with which lower electrode sheath by knowing which of the plurality of collection containers is a collection container. The problematic lower electrode sheath can be easily identified.
Further, a second invention is characterized in that the table in which the same number of collection containers as the lower electrode sheath are repeatedly rotated and stopped in synchronization with the movement of the circular movable base on which the lower electrode sheath is installed, and the lower portion stopped at the take-out position. By moving the closed container taken out of the electrode sheath by the collection machine to the collection container stopped at the collection position via the flow passage, the closed container manufactured for each lower electrode sheath is collected in a separate collection container. A sealed container manufacturing apparatus characterized in that it can be manufactured. Thereby, the closed containers manufactured for each lower electrode sheath can be collected in separate collection containers, and a collection device that is relatively inexpensive and easy to maintain can be obtained.
According to a third aspect of the present invention, a flow path on a table on which the same number of collecting containers as the lower electrode sheath are repeatedly rotated and stopped in synchronization with the movement of the circular movable base on which the lower electrode sheath is installed, and the take-out position is set. By moving the closed container taken out from the lower electrode sheath stopped by the collecting device to the collecting container through the flow passage, the closed container manufactured for each lower electrode sheath can be collected in a separate collecting container. A closed container manufacturing apparatus characterized in that it can be manufactured. Thereby, the closed containers manufactured for each lower electrode sheath can be collected in separate collection containers, and a collection device that is relatively inexpensive and easy to maintain can be obtained.
In a fourth aspect of the present invention, the supply of the components of the closed container to an arbitrary lower electrode sheath is stopped, and the welding at the lower electrode sheath is stopped, whereby the closed container of the specific lower electrode sheath is stopped. The sealed container manufacturing apparatus is characterized in that the manufacturing can be stopped and the manufacturing of the sealed container can be continued in the remaining lower electrode sheath. Thus, even if a problem occurs in a part of the lower electrode sheath, by stopping the production of the sealed container only in the lower electrode sheath in which the problem has occurred, the production can be continued without stopping the entire apparatus. As a result, manufacturing delays can be minimized.
A fifth aspect of the present invention provides a closed container manufacturing apparatus capable of collecting closed containers manufactured for each lower electrode sheath into separate collection containers, and an airtightness of the closed container manufactured by the manufacturing apparatus. It consists of an airtightness inspection device that performs an inspection, and by performing an airtightness inspection of the closed container by this airtightness inspection device for each collection container, if a poor airtightness occurs in the closed container, the poorly sealed airtight container is stored. Identify the lower electrode sheath that produced the hermetically sealed hermetic container from the recovery container that is being used, stop manufacturing the hermetic container only with this identified lower electrode sheath, and use the hermetically sealed type in the remaining lower electrode sheath. It is characterized by continuing to manufacture containers. If the cause of the poor airtightness of the closed container is found to be a problem of the specific lower electrode sheath by the airtightness inspection, the production of the closed container is stopped only at the specific lower electrode sheath, thereby causing the poor airtightness. Occurrence is eliminated, and the closed container manufacturing apparatus can continue production although the manufacturing efficiency is slightly reduced. Also, since the problematic lower electrode sheath can be easily specified, it does not take much time to specify the problematic lower electrode sheath.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A closed container manufacturing apparatus according to the present invention will be described below with reference to the drawings. Here, FIG. 1 is a plan view of the present invention, and FIG. 2 is a front view thereof. 3 and 4 are cross-sectional views for explaining the operation. This closed container manufacturing apparatus 1 is composed of a welding device 2 and a recovery device 3 as shown in FIG.
As shown in FIG. 2, the welding apparatus 2 has a welding machine 4 having an upper welding electrode 4A and a lower welding electrode 4B, and a plurality of welding machines 4 arranged on a circular movable base 7 so as to be able to store the components of a closed container. , And an upper electrode sheath 5 in contact with the lower electrode sheath 6. The lower welding electrode 4B of the welding machine 4 is installed on the back side of the pedestal 26 of the circular movable base 7 when the manufacturing apparatus is viewed from the front. The components of the closed container are charged into the lower electrode sheath 6 by the component charging device 25. The collecting device 3 communicates the plurality of collecting containers 8 installed on the table 17, a collecting device 9 for taking out the closed container from the lower electrode sheath 6, and the collecting device 9 and the collecting container 8. It comprises a flow passage 10 which is inclined to move the container to the collection container 8. The same number of lower electrode sheaths 6 and the same number of collection containers 8 are arranged, and their movements are synchronized as described later.
As shown in FIG. 3, the upper electrode sheath 5 has a cylindrical upper guide 11 and a piston-like first encapsulation electrode which slides air-tightly with respect to the upper guide 11. Insulated and fixed. The first sealing electrode is composed of a shaft electrode 12 and an upper welding tip 13, and an exhaust pipe 29 and a filling pipe 30 for replacing gas inside the electrode sheath are connected to the upper guide 11.
The lower electrode sheath 6 has a lower guide 14 and a second sealing electrode. The lower guide 14 of the lower electrode sheath 6 is insulated and fixed on the circular movable base 7. The second encapsulated electrode is composed of a lower electrode contact 15 and a lower welding tip 16, and the lower end of the lower electrode contact 15 can be brought into contact with the lower welding electrode 4 </ b> B. A pocket for storing parts is provided.
The upper electrode sheath 5 is configured to move up and down along a guide bar 21 supporting the support via a support 20 and to contact the lower electrode sheath 6. A plurality of lower electrode sheaths 6 are evenly arranged at equal angles on the same circumference with respect to the center of rotation of the circular movable table 7, and the circular movable table 7 repeatedly rotates and stops around its center. Further, the upper welding electrode 4A and the lower welding electrode 4B of the welding machine 4 are installed so as to sandwich the upper and lower electrode sheaths from above and below where the axes of the upper electrode sheath 5 and the lower electrode sheath 6 coincide.
Next, the operation of the closed container manufacturing apparatus 1 will be described. As shown in FIG. 3, a metal container 27 and a cover plate 28, which are components of the closed container, are put into a pocket of the lower welding tip 16 of the lower electrode sheath 6 by a component feeder 25. The lower electrode sheath 6 is rotated by the circular movable base 7 and sequentially stops at a position substantially coincident with the axis of the upper electrode sheath 5. When the lower electrode sheath 6 stops at a position coinciding with the axis of the upper electrode sheath 5, the upper electrode sheath 5 descends along the guide bar 21, and comes into contact with the lower electrode sheath 6 as shown in FIG. Is composed. The inside of the sealed container is replaced with an inert gas such as helium gas in an airtight space formed by the upper and lower electrode sheaths. At this time, the lower electrode contact body 15 is pushed down, and its lower end contacts the lower welding electrode 4B. Next, the upper welding electrode 4A of the welding machine 4 descends, contacts the upper end of the shaft electrode 12 of the upper electrode sheath 5, and pushes down the shaft electrode. The shaft electrode 12 slides down with respect to the upper guide 11, and the upper welding tip 13 pushed down together with the shaft electrode 12 comes into contact with the lid plate 28, which is a component of the closed container, and when the contact pressure reaches a predetermined value. A welding current is caused to flow between the upper welding electrode 4A and the lower welding electrode 4B, and the lid plate 28 is hermetically welded to the open end of the metal container 27 to complete the hermetic container.
A sealed container manufactured by this welding apparatus is a closed container constituted by a metal container and a cover plate. For example, a thermally responsive switch having a thermally responsive plate of bimetal or the like, , And is configured as an acceleration responsive switch for detecting vibration, inclination, or acceleration.
In this embodiment, the manufactured closed container is collected by the collecting device 3. The collecting device 3 includes a collecting container 8 installed on a table 17 shown in FIG. 1, a collecting machine 9 for removing the manufactured sealed container from the lower electrode sheath 6, and a flow passage connecting the collecting machine 9 and the collecting container 8. 10 is comprised. The number of the collection containers 8 is the same as the number of the lower electrode sheaths 6, and the operations of the table 17 and the circular movable table 7, respectively, are synchronized. The closed type container is taken out of the lower electrode sheath 6 by the take-out part tip 23 of the collecting machine 9, and the take-out part 22 moves along the slide jig 24 and moves to the flow passage 10. Thereafter, the closed type container slides down from the upper end 10B of the flow passage 10 to the lower end 10C and is collected in the collection container 8.
In this embodiment, as shown in FIG. 1, the same number of collecting containers 8 as the lower electrode sheath 6 are equally arranged on the same circumference of the table 17 at an equal angle, and the table 17 is repeatedly rotated and stopped. . Here, the opening of the collection container 8 is set to stop at a position overlapping the lower end 10C of the flow passage 10. The number of lower electrode sheaths 6 and the number of collection containers 8 are the same, and the operation of rotating / stopping the circular movable table 7 and the operation of rotating / stopping the table 17 in each case is synchronized with the collection machine 9. The lower electrode sheath 6 and the collection container 8 communicated with the flow passage 10 always have the same combination. Therefore, the closed container manufactured by each lower electrode sheath 6 can be collected in a fixed collection container 8. Further, since the collecting container 8 corresponding to the lower electrode sheath 6 stopped at the takeout position stops at the collecting position, the collecting machine 9 is manufactured for each lower electrode sheath 6 simply by moving the closed container to the flow passage 10. The closed containers can be collected in the respective collection containers 8. Therefore, even if a problem occurs, it is possible to specify which lower electrode sheath 6 is the problem without investigating all the lower electrode sheaths 6, so that the efficiency of the investigation work can be improved.
Here, for example, the sealed container manufactured by replacing the collecting machine 9 with a robot arm or the like can be distributed to a plurality of collecting containers. However, such a robot arm is expensive and requires a lot of maintenance. Therefore, according to the present embodiment, it is possible to obtain a relatively inexpensive and easy-to-maintain recovery device without using such an expensive robot arm.
Next, another embodiment will be described. Since the same parts are given the same numbers, detailed description will be omitted. In this embodiment, the same number of collection containers 8 as the lower electrode sheath 6 shown in FIG. 5 are evenly arranged at the same angle on the same circumference of the fixed table 18. A movable table 19 is installed at the center of the table 18 so as to be rotatable around the center of the table 18. The flow passage 30 is attached to the movable base 19, and the upper end 30B of the flow passage 30 is installed so as to overlap the rotation center of the movable base 19, and when the movable base 19 rotates, the flow passage 30 is centered on the upper end 30B. Rotate. When the movable table 19 stops, the lower end 30 </ b> C of the flow passage 30 is set to stop at the opening of the collection container 8. In the present embodiment, the flow path 30 is repeatedly rotated and stopped in synchronization with the circular movable base 7, so that the flow path 30 is stopped on the collection container 8 corresponding to the lower electrode sheath 6 stopped at the take-out position. Reference numeral 9 indicates that the closed containers manufactured for each lower electrode sheath 6 can be collected in each of the collecting containers 8 simply by moving the closed container to the upper end 30B of the flow passage which is the center of rotation that does not always move. . According to this embodiment, the same number of the collection containers 8 are provided for the lower electrode sheath 6 so that it is possible to specify where the failure of the lower electrode sheath 6 occurs by making one-to-one correspondence. Can be achieved.
However, for example, as described above, even if the lower electrode sheath having a defect can be specified, if the scheduled maintenance work is scheduled in advance, the specified lower electrode sheath 6 is not used immediately than the maintenance work is started. In some cases, it may be more efficient to temporarily stop the operation in step 1 and continue the operation until the remaining lower electrode sheath 6 reaches the planned quantity. Therefore, a sealed container manufacturing apparatus 1 capable of such a response will be described below. The closed container manufacturing apparatus 1 includes a component input device 25 for inputting the components of the closed container, rotating and stopping the circular movable base 7 on which the lower electrode sheath 6 is installed, gas replacement and welding by the welding machine 4, and a collecting machine 9. A series of operations for manufacturing a closed container such as removal and movement of the closed container by rotation of the table 17 or the flow passage 30 in which the collection container 8 is installed is controlled by a control device (not shown). By repeatedly performing the above operation, a closed container is continuously manufactured. The closed container manufacturing apparatus 1 supplies components of the closed container to the lower electrode sheath 6 specified by the control device by the component input device 25, and performs gas replacement and welding in a state where the closed container production is continued. By controlling not to perform the welding by the machine 4 and the removal operation by the recovery machine 9, it is possible to stop the production of the closed container at the lower electrode sheath 6 by designating it.
More specifically, the lower electrode sheath 6 whose production of the closed container is stopped is stopped at the component supply position of the closed container by the rotation of the circular movable base 7, but the control unit controls the component input device. Numeral 25 is controlled so that the metal container 27 and the cover plate 28, which are the components, are not charged. The lower electrode sheath 6 stops at a position coinciding with the axis of the upper electrode sheath 5, the upper welding electrode 4A of the welding machine 4 does not descend, and a welding current flows between the upper welding electrode 4A and the lower welding electrode 4B. It is controlled not to flow. Furthermore, the upper electrode sheath 5 and the lower electrode sheath 6 are in contact with each other, but the gas replacement operation is not performed, and even if the lower electrode sheath 6 is stopped at the closed container collecting position, the collecting machine 9 does not operate. .
As described above, even while the production of the closed container is stopped at the specific lower electrode sheath 6, the components of the closed container are supplied to the remaining lower electrode sheath 6 by the component input device 25. The gas replacement and welding by the welding machine 4 and the collection of the sealed container manufactured by the collecting machine 9 are performed, and the manufacturing of the sealed container is continued. As a result, compared to the case where the hermetic container manufacturing apparatus 1 is completely stopped and the maintenance work of the electrodes is performed when a failure occurs only in the specific lower electrode sheath 6, the manufacturing can be continued without significantly lowering the manufacturing efficiency. it can.
Next, a closed container manufacturing system in which the above-described closed container manufacturing apparatus 1 and an airtightness inspection apparatus are combined will be described. One example of the airtightness inspection device used here is a helium leak detector, and this helium leak detector checks the airtightness of the sealed container by detecting leakage of helium gas sealed in the sealed container. The closed container manufacturing apparatus 1 has a plurality of lower electrode sheaths 6 as described above, and the closed containers manufactured for each of the lower electrode sheaths 6 are collected in separate collection containers 8. Further, the production of the hermetically sealed container can be stopped at the specific lower electrode sheath 6 while the production of the whole hermetically sealed container is continued. When the hermetic seal is inspected for each collection container 8 and a hermetic container with poor airtightness is detected, the hermetic containers manufactured with the respective lower electrode sheaths 6 are collected in the fixed collection container 8. From the container 8, the lower electrode sheath 6 which has produced a hermetically sealed airtight container can be easily specified. The specified lower electrode sheath 6 can be specified to the control device, and the production is stopped only at the specified lower electrode sheath 6. With this measure, it is possible to suppress the occurrence of a hermetically sealed airtight container, and to continue manufacturing without stopping the entire manufacturing apparatus.
A case in which a hermetically sealed hermetic container is detected using the hermetic container manufacturing system will be described. When a hermetically sealed airtight container is detected, the production of the airtight container in the lower electrode sheath 6 of the airtight container manufacturing apparatus 1 corresponding to the collection container 8 in which the airtight container is stored is immediately stopped, and In the lower electrode sheath 6 described above, the production of the closed container is continued. If a hermetically sealed hermetic container is randomly detected from some of the collection containers 8, a cause of the hermetic hermeticity of the hermetic container is, for example, a problem of the lower electrode sheath 6 that manufactured these hermetic containers, Alternatively, there is a problem of the whole closed container manufacturing apparatus 1 or a problem of components of the closed container. In such a case, the entire closed container manufacturing apparatus 1 is stopped, the lower electrode sheath 6 is maintained, the components of the closed container are reviewed and replaced, and then the closed container manufacturing apparatus 1 is used. Resume container production. A hermetic container with poor airtightness is detected from a certain collection container 8, and while production of the hermetic container in the lower electrode sheath 6 corresponding to this collection container 8 is stopped, out of several tens of hermetic containers, The hermetically sealed container is identified and the location of the hermetic container, such as leaking from a weld or a component, is investigated in detail.
When the location of the hermetically sealed container is a welded portion, it can be determined that an abnormality such as abrasion of the lower welding tip 16 of the lower electrode sheath 6 has occurred, and a hermetically sealed hermetically sealed container will be manufactured in the future. Therefore, the production of the closed container is stopped until the lower welding tip 16 of the lower electrode sheath 6 is replaced. The replacement of the lower welding tip 16 of the lower electrode sheath 6 may be performed only in a specific lower electrode sheath 6 and can be performed in a short time. Further, when the location of the hermetic seal of the hermetic container is other than the welded portion, it can be determined that the hermetic seal of the hermetic container has occurred by accident, and the lower electrode sheath 6 corresponding to this collection container 8 will be used in the future. Even if it is manufactured, there is a low possibility that a hermetic container with poor airtightness is generated. Therefore, the manufacturing apparatus of the hermetic container manufacturing apparatus 1 is operated to cancel the production stop and restart the manufacturing of the hermetic container.
【The invention's effect】
As described above, the closed container manufacturing apparatus according to the present invention is configured such that the table on which the collecting container is installed or the flow passage for moving the closed container from the collecting machine to the collecting container is rotated and stopped to thereby lower the closed container. The closed containers manufactured for each electrode sheath are collected in separate collection containers. Even if an expensive device such as a robot arm is not installed, a collection device that is relatively inexpensive and easy to perform maintenance work can be obtained by combining a collection machine and a rotating table or a rotating flow passage provided with a collection container. be able to.
By combining the closed container manufacturing device and the airtightness inspection device, the closed containers manufactured for each lower electrode sheath of the closed container manufacturing device are collected in separate collection containers, and the airtightness of the closed container is measured. By performing an inspection for each collection container, when a hermetically sealed airtight container is detected, the manufactured lower electrode sheath can be easily specified. Further, the sealed container manufacturing apparatus can stop the production of the sealed container at a specific lower electrode sheath while continuing the production of the sealed container at another lower electrode sheath. Therefore, when a hermetically sealed container is detected, the production of the hermetically sealed container is stopped at a specific lower electrode sheath, during which the cause of the hermetically sealed container is investigated, and a specific lower electrode is determined according to the cause. It is determined whether the production of the sealed container with the sheath should be resumed or subsequently stopped. Since the production of the closed container can be stopped at the lower electrode sheath which is a problem, the production efficiency is not significantly reduced as compared with the case where the closed container production device is completely stopped and the lower electrode sheath is maintained. Production can continue.
