Description

Resin container coating apparatus and resin container manufacturing system

The present invention relates to a resin container coating apparatus for forming a thin film on the inner surface of a resin container and a resin container manufacturing system including the resin container coating apparatus.

Resins such as polyethylene, which are widely used for household goods, generally have the property of permeating low-molecular gases such as oxygen and carbon dioxide, and the property that low-molecular organic compounds sorb inside them. Also have. For this reason, when using resin as a container, compared with other containers, such as glass, it is known that it will receive various restrictions by the use object, usage form, etc. For example, in the case of using a carbonated drinking water filled in a resin container, the carbonic acid permeates outside through the container, and it may be difficult to maintain the quality as carbonated drinking water for a long period of time.

Therefore, when manufacturing a resin container, plasma CVD film formation technology is used for the inner surface of the resin container in order to eliminate the inconvenience due to the permeation of the low molecular gas in the resin container and the sorption of the low molecular organic compound. For example, a film that performs film formation such as DLC (Diamond Like Carbon) coating is known. In addition, from the viewpoint of improving mass production efficiency for mass production of coated resin containers, while the thin film is formed on the inner surface of the resin container held on a part of the container holding part, In this part, a coating apparatus capable of exchanging a coated resin container with an unformed resin container is disclosed (for example, see Patent Document 1).

However, the coating apparatus described in Patent Document 1 has a common position for supplying an undeposited resin container and a position for extracting a coated resin container. For this reason, the supply process and the removal process of the resin container cannot be performed in parallel, and it is difficult to improve the mass production efficiency of the resin container that has been coated.

Therefore, Patent Document 2 proposes a coating apparatus for a resin container that can improve the efficiency of mass production of a coated resin container.

In this configuration, it is necessary to ensure a predetermined clearance between the bottom surface of the turntable and the bottom surface in the recess of the machine base so that the turntable can rotate smoothly.

However, in this configuration in which the clearance is ensured, the impact force when the container holding member and the electrode member are combined in the coating process is not transmitted to the machine base installed on the floor surface, and the container holding member is installed. The rotating mechanism including the rotating table receives most of the impact force. Since this impact force is transmitted to the rotating mechanism at every coating process, it is likely to cause a failure of the rotating mechanism, and periodic maintenance is required for the rotating mechanism.

In addition, when the chamber lid portion 11 is abutted against the

container holding members

5a, 5b, 5c, and 5d, the lower shield member 70 and the upper shield member 140 are brought into contact with each other via the conductive seal member 72 and are electrically connected. Connected. The lower shield member 70 and the upper shield member 140 form a shielding space, and the chamber 30 including the lower chamber 60 and the upper chamber 130 is placed in the shielding space. Further, the lower shield member 70 and the upper shield member 140 are sealed by a conductive seal member 72 provided on the lower shield member 70.

Further, when the chamber lid 11 and the

container holding members

5 a, 5 b, 5 c, 5 d are combined, the internal electrode 13 disposed at the lower position is raised, and the tip thereof is accommodated in the storage chamber S of the chamber 30. The resin container 8 is inserted.

As described above, when the chamber lid portion 11 and the

container holding members

5a, 5b, 5c, and 5d are combined and the internal electrode 13 is inserted into the resin container 8 from the mouth of the resin container 8, the storage chamber The air in S is exhausted by the vacuum pump through the exhaust line 80, and the storage chamber S is evacuated. In this state, the source gas is supplied from the gas supply unit 14, and the supplied source gas is discharged from the tip of the pipe-shaped internal electrode 13 into the resin container 8. After the release of the source gas, electric power is supplied to the chamber 30 from the external high frequency power supply 15. Thereby, plasma is generated by a potential difference generated between the chamber 30 which is an external electrode and the internal electrode 13, and a film is collectively formed on the internal surfaces of the eight resin containers 8.

Further, in a state where the

container holding members

5a, 5b, 5c, 5d and the chamber lid portion 11 are combined, the lower shield member 70 and the upper shield member 140 are brought into contact with each other to be electrically connected and shielded. Create a space. Then, the chamber 30 including the lower chamber 60 of the

container holding members

5a, 5b, 5c, and 5d and the upper chamber 130 of the chamber lid portion 11 is disposed in the shielding space. Therefore, propagation of high frequency generated during the coating process to the outside is prevented.

The coating process in the coating unit 10 is performed based on each control signal output from a control unit (not shown).

By the way, when the chamber cover part 11 is lowered and the

container holding members

5a, 5b, 5c, 5d are combined, the

container holding members

5a, 5b, 5c, 5d have an impact force downward from the chamber cover part 11. Works. On the other hand, there is a predetermined clearance between the bottom surface of the turntable 3 and the bottom surface in the recess 300 of the machine base 2. Further, the

container holding members

5 a, 5 b, 5 c, and 5 d are installed on the turntable 3 at positions separated from the support shaft 7 of the turntable 3 by a predetermined distance radially outward.

For this reason, for example, in the structure in which the

container holding members

5a, 5b, 5c, and 5d are fixed to the turntable 3 as in the apparatus described in Patent Document 2, the

container holding members

5a, 5b, 5c, The impact force when 5d and the chamber lid 11 are combined is not easily transmitted to the machine base 2 installed on the floor, and this impact force is mainly received by the turntable 3. Then, when this impact force is applied to a part of the turntable 3 that is a predetermined distance away from the support shaft 7 every time the coating process is performed, the drive mechanism 6 may break down. For example, there is a possibility that the shape of the turntable 3 is deformed, or the joint portion between the turntable 3 and the support shaft 7 is deformed. For this reason, the apparatus of Patent Document 2 requires periodic maintenance on the drive mechanism 6.

Therefore, for example, it is conceivable to provide a sliding member in the clearance between the bottom surface of the turntable 3 and the bottom surface in the recess 300 of the machine base 2. In this configuration, while the smooth rotation of the turntable 3 is ensured, the impact force when the

container holding members

5a, 5b, 5c, 5d and the chamber lid portion 11 are combined with each other through the sliding member is used for the machine base 2. Can be received.

However, such a sliding member is expensive and increases the cost of the apparatus. Further, since the sliding member wears, periodic maintenance of the sliding member is required.

In contrast, in the resin container coating apparatus 1 according to the present embodiment, the

container holding members

5a, 5b, 5c, and 5d are moved before the

container holding members

5a, 5b, 5c, and 5d are combined with the chamber lid portion 11. Since the

container holding members

5 a, 5 b, 5 c, 5 d and the chamber lid 11 are combined with each other, the impact force is not directly transmitted to the turntable 3 because it moves to a separated position away from the turntable 3. For this reason, it is possible to reduce the possibility that the drive mechanism 6 breaks down due to the above-described impact force generated every time the coating process is performed, and it is possible to reduce the frequency of maintenance.

Further, the moving pipeline portion 82 constituting the exhaust pipeline 80 is moved up and down by the air cylinder 85. For this reason, at the moment when the impact force is generated, the

container holding members

5a, 5b, 5c, and 5d can move slightly from the separated position toward the turntable 3. Thereby, the impact force when the

container holding members

5a, 5b, 5c, 5d and the chamber lid 11 are combined can be buffered by moving the

container holding members

5a, 5b, 5c, 5d slightly downward. it can. Thereby, the

container holding members

5a, 5b, 5c and 5d are also difficult to break.

FIG. 7 is a cross-sectional view taken along the line CC of FIG. 1, and shows the cleaning unit 20 provided at the cleaning processing position P3. The cleaning unit 20 includes a container holding member 5 c, a container pressing part 21, a container pressing support part 22, a nozzle 23, and a compressed air supply part 24.

The container pressing part 21 is a member for preventing the resin container 8 from coming off, pressing the resin container 8 fitted in the container holding hole 9c from above. The container pressing portion 21 includes a pressing plate 21a and a pressing arm 21b that supports the pressing plate 21a at one end. The other end of the pressing arm 21 b is attached to the container pressing support portion 22. The container holding | suppressing part 21 is supported so that a movement to an up-down direction (arrow S direction shown in FIG. 7) is possible.

The nozzles 23 are pipe members respectively inserted into the resin containers 8 held in the container holding holes 9c of the container holding member 5c. The nozzle 23 is connected to the compressed air supply unit 24. The air supplied from the compressed air supply unit 24 is discharged into the resin container 8 through the nozzle 23.

By the way, at the time of film formation in the coating unit 10 described above, a film may adhere to the internal electrode 13 or the like inserted into the resin container 8. In this case, when the coating process is repeated a plurality of times, the film gradually becomes a large deposit, and the deposit may be peeled off inside the resin container 8. In addition, deposits adhering in the exhaust pipe 80 may be wound up by the air flow when the atmosphere is released and enter the resin container 8.

In the cleaning unit 20, a nozzle 23 is inserted into each resin container 8, and compressed air is blown into the resin container 8 from the nozzle 23. At this time, the container pressing portion 21 is disposed and pressed above the resin container 8 so that the resin container 8 set on the container holding member 5c is not blown away by blowing compressed air. Thereby, particles such as dust, dust, dust, and foreign matters adhering to the inner surface of the container during film formation can be removed to the outside of the resin container 8.

Next, operation | movement of the coating apparatus 1 for resin containers of the said structure is demonstrated.
In the initial state in which the coating process is performed, the four

container holding members

5a, 5b, 5c, and 5d are all empty, that is, the resin container 8 is not placed. This state will be described below with reference to FIG. 1 as this initial state.

In the initial state, first, the uncoated resin container 8 that is not coated is inserted into the container holding hole 9a of the container holding member 5a disposed at the container supply position P1.

When the supply of the resin container 8 to the container holding member 5a is completed, the turntable 3 subsequently rotates 90 degrees about the support shaft 7 in the arrow Q direction. By this rotation, the container holding member 5a moves to the coating processing position P2.

At this time, the other

container holding members

5b, 5c and 5d are also rotated by the same angle in the direction of arrow Q, the container holding member 5b is moved to the cleaning processing position P3, the container holding member 5c is moved to the container removal position P4, The container holding member 5d moves to the container supply position P1.

When the container holding member 5a moves to the coating processing position P2, the coating process is started on the resin container 8 supplied to the container holding member 5a at the coating processing position P2. The contents of the coating process are as described above.

While the coating process is being performed on the resin container 8 of the container holding member 5a at the coating processing position P2, in parallel with this process, the container holding hole 9d of the container holding member 5d disposed at the container supply position P1. A process of inserting a non-film-formed resin container 8 is performed.

When the coating process to the resin container 8 supplied to the container holding member 5a and the container supply process to the container holding member 5d arranged at the container supply position P1 are completed, the turntable 3 further rotates 90 degrees. The container holding member 5a moves to the cleaning processing position P3.

At this time, the other

container holding members

5b, 5c, and 5d are also rotated by the same angle, the container holding member 5b is moved to the container take-out position P4, the container holding member 5c is moved to the container supply position P1, and the container holding member 5d is moved. Moves to the coating processing position P2.

When the container holding member 5a moves to the cleaning processing position P3, the cleaning process is started on the resin container 8 held by the container holding member 5a at the cleaning processing position P3. The contents of the cleaning process are as described above.

While the cleaning process is being performed on the resin container 8 of the container holding member 5a at the cleaning process position P3, the resin container 8 of the container holding member 5d disposed at the coating process position P2 is coated in parallel with this process. Processing is performed. Moreover, the process which inserts the non-film-formation resin container 8 in the container holding hole 9c of the container holding member 5c arrange | positioned in the container supply position P1 is implemented.

The cleaning process for the resin container 8 held by the container holding member 5a, the coating process for the resin container 8 held by the container holding member 5d, and the container holding member 5c disposed at the container supply position P1 When the container supply process is completed, the turntable 3 further rotates 90 degrees, and the container holding member 5a moves to the container removal position P4.

At this time, the other

container holding members

5b, 5c, and 5d also rotate by the same angle, the container holding member 5b moves to the container supply position P1, the container holding member 5c moves to the coating processing position P2, and the container holding member 5d. Moves to the cleaning processing position P3.

When the container holding member 5a moves to the container removal position P4, the process of taking out the film-formed resin container 8 placed on the container holding member 5a is started at the container removal position P4. The resin container 8 taken out from the resin container coating apparatus 1 is conveyed to a filling apparatus that fills the interior thereof with a content such as a liquid.

While the process of taking out the film-formed resin container 8 held by the container holding member 5a at the container take-out position P4 is being performed, in parallel with this process, the container holding member 5d disposed at the cleaning process position P3 A cleaning process is performed on the resin container 8. Further, the coating process is performed on the resin container 8 of the container holding member 5c disposed at the coating process position P2. In addition, a container supply process is performed in which a non-film-formed resin container 8 is inserted into the container holding hole 9b of the container holding member 5b disposed at the container supply position P1.

When the coating process, the cleaning process, the removal process, and the container supply process are completed, the turntable 3 further rotates 90 degrees, and the container holding member 5a moves again to the container supply position P1. At this time, the container holding member 5a is in an empty state in which the resin container 8 is not supplied.

Then, as described above, the supply process of the undeposited resin container 8 is performed on the container holding member 5a that has returned to the container supply position P1. Further, when the rotation is further repeated, the above-described operations are sequentially repeated at the respective positions P1 to P4.

The container supply process, the coating process, the cleaning process, the removal process, and the container supply process described above are set to finish within a predetermined time. In this example, the above four processes are set so that the processes are completed within 10 seconds, for example, and the turntable 3 rotates 90 degrees in the direction of the arrow Q about the support shaft 7 every 10 seconds, for example. The operations described above are repeated at each of the positions P1 to P4.

As described above, according to the resin container coating apparatus 1 according to the present embodiment, the

container holding members

5a, 5b, 5c are combined before the

container holding members

5a, 5b, 5c, 5d and the chamber lid portion 11 are combined. , 5d move to a position separated from the top of the turntable 3, so that the impact force when the

container holding members

5a, 5b, 5c, 5d and the chamber lid 11 are combined is directly transmitted to the turntable 3. do not do. For this reason, it is possible to reduce the possibility that the drive mechanism 6 breaks down due to the above-described impact force generated every time the coating process is performed, and it is possible to reduce the frequency of maintenance.

Moreover, according to the coating apparatus 1 for a resin container according to the present embodiment, a process for supplying an undeposited resin container 8, a process for performing a coating process, a process for performing a cleaning process, and a resin container 8 having a film formed thereon. Therefore, it is possible to improve the mass production efficiency of manufacturing the resin container 8 that requires a coating process.

Thus, according to the present embodiment, it is possible to reduce the frequency of maintenance caused by the coating process while improving the mass production efficiency of the coated resin container 8.

In addition, the turntable 3 can be reduced in size and cost, which can contribute to the cost reduction of the entire apparatus.

Further, since the guide pins 42 for guiding the movement of the

container holding members

5a, 5b, 5c, 5d to the separated position are provided on the turntable 3, the

container holding members

5a, 5b, 5c, 5d are separated accurately. It can be moved to a position. Further, the

container holding members

5a, 5b, 5c and 5d can be prevented from moving to a position different from the separated position.

Moreover, the guide pins 42 can prevent the

container holding members

5a, 5b, 5c, and 5d from moving in the horizontal direction on the turntable 3. Thereby, it is possible to suppress the occurrence of displacement of the

container holding members

5a, 5b, 5c, and 5d due to the impact force when the

container holding members

5a, 5b, 5c, and 5d are combined with the chamber lid portion 11.

Further, the moving mechanism 90 is connected to the

container holding members

5a, 5b, 5c, and 5d disposed at the coating processing position P2, and the lower chamber 60 and the chamber lid portion of the

container holding members

5a, 5b, 5c, and 5d. The exhaust member which comprises the exhaust pipe 80 for exhausting the air of the storage chamber S formed with the 11 upper chambers 130 outside is used. That is, by using the exhaust member necessary for the coating process as the moving mechanism 90, it is possible to realize a mechanism for moving the

container holding members

5a, 5b, 5c, and 5d to the separated position while suppressing an increase in the number of parts. .

Further, in a state where the

container holding members

5a, 5b, 5c, 5d and the chamber lid portion 11 are combined, the

container holding members

5a, 5b are within the shielding space formed by the lower shield member 70 and the upper shield member 140. , 5c, 5d, the chamber 30 composed of the lower chamber 60 and the upper chamber 130 of the chamber lid 11 is arranged. Thereby, it is possible to prevent the high frequency generated during the coating process from propagating to the outside of the apparatus.

In addition, the lower shield member 70 and the upper shield member 140 are connected to each other via the conductive seal member 72 made of an elastic material having conductivity provided in the lower shield member 70, so that the sealed space is sealed. Is easier to secure.

Here, the lower chamber 60 and the upper chamber 130 are designed to be thick enough to withstand vacuum, but there is no problem as long as the lower shield member 70 and the upper shield member 140 can be electrically shielded. Therefore, the lower shield member 70 and the upper shield member 140 can be designed to be thinner than the lower chamber 60 and the upper chamber 130, but the possibility of deformation due to impact force must also be taken into consideration.

In the present embodiment, when the

container holding members

5a, 5b, 5c, 5d and the chamber lid 11 are combined by the conductive sealing member 72 made of an elastic material having conductivity provided in the lower shield member 70, the lower side The impact force generated between the shield member 70 and the upper shield member 140 can be reduced. Thereby, the lower shield member 70 and the upper shield member 140 can be thinned and the cost can be reduced.

Next, the resin container manufacturing system 230 provided with the said resin container coating apparatus 1 is demonstrated.
FIG. 8 is a plan view of an embodiment of the resin container manufacturing system 230 as viewed from above. The resin container manufacturing system 230 includes a molding machine (an example of a resin container manufacturing apparatus) 240 that manufactures the resin container 8, a resin container coating apparatus 1 that performs a coating process on the resin container 8, and a resin manufactured by the molding machine 240. A robot arm (an example of a resin container transport device) 250 that transports the container 8 to the resin container coating apparatus 1 is provided. The resin container coating apparatus 1 is the same apparatus as the resin container coating apparatus described in the above embodiment.

The molding machine 240 includes a raw material supply stage 241 to which the raw material of the resin container 8 is supplied, a preform molding stage 242 for molding a preform, a temperature adjustment stage 243 for making the temperature distribution of the preform uniform, air And a take-out stage 245 for taking out the molded resin container 8. The number of resin containers 8 arranged in parallel to the take-out stage 245 and the pitch of the resin containers 8 (die pitch) are the

container holding members

5a, 5b, 5c arranged at the container supply position P1 of the resin container coating apparatus 1. , 5d, the number of

container holding holes

9a, 9b, 9c, 9d and the pitch thereof are set.

The robot arm 250 is disposed between the molding machine 240 and the resin container coating apparatus 1. The robot arm 250 takes out the resin container 8 placed on the take-out stage 245 of the molding machine 420, and takes the taken-out resin container 8 at the container supply position P1 of the resin container coating apparatus 1. Transport to. The robot arm 250 holds the conveyed resin container 8 by fitting it into the container holding hole 9a of the container holding member 5a.

As described above, according to the resin container manufacturing system 230 of the present embodiment, the resin container 8 held by the molding machine 240 is directly supplied to the resin container coating apparatus 1 by the robot arm 250. For this reason, compared with the structure which conveys the resin container 8 manufactured with the molding machine 240 to a coating apparatus by a belt conveyor, the alignment operation | work for installing in a coating apparatus becomes unnecessary, and mass-production efficiency improves more.

Further, by making the number and pitch (mold pitch) of the resin containers 8 of the take-out stage 245 correspond to the number and pitch of the

container holding holes

9a, 9b, 9c and 9d at the container supply position P1. The resin container 8 can be reliably delivered by the robot arm 250, and the mass production efficiency can be further improved.

Here, the manufacturing apparatus of the resin container 8 and the coating apparatus may be connected and used (see, for example, Japanese Patent Laid-Open No. 2005-036260 and Japanese Patent Laid-Open No. 2005-2469). In this way, in the apparatus that uses the manufacturing apparatus for the resin container 8 and the coating apparatus connected to each other, the resin containers 8 formed in the final shape by the manufacturing apparatus are individually transferred to the individual conveying members (under the chamber) of the coating apparatus. It is necessary to supply it in a state where it is aligned with the part). This type of apparatus is mainly used to manufacture a resin container 8 having a general-purpose shape that is mass-produced.

By the way, the resin container 8 to be coated includes not only a mass-produced and general-purpose shape but also a small-sized or flat shape and a small-volume product. For resin containers 8 that are mainly produced in small quantities, such as small and flat shapes, it is difficult to transport them in an aligned state and supply them individually to individual transport members one by one, which increases the efficiency of the coating process. It is one of the causes of the decrease.

On the other hand, according to the resin container manufacturing system 230 of the present embodiment, the

container holding members

5a, 5b, and 5c of the resin container coating apparatus 1 are used as they are as they are manufactured by the molding machine 240 and in an upright state. , 5d, the efficiency of the coating process is unlikely to decrease even for resin containers 8 that are small, flat, or the like and are produced in small quantities.

In addition, an apparatus that connects and uses a manufacturing apparatus for the resin container 8 and a coating apparatus continuously supplies the resin containers 8 one by one to individual conveying members (such as the lower part of the chamber), Flow along the path. In such a rotary type apparatus, for example, in the case of an apparatus having specifications that can arrange 20 to 50 resin containers 8 in a circle at once (specs that can process 10,000 to 30,000 containers per hour), 20 Since the resin container 8 is continuously supplied to the supply port only up to 50 times and moved to the next position, the rotation mechanism of the apparatus is operated as many as the number of resin containers 8 to be supplied. The risk of failure is susceptible to the number of resin containers 8. In addition, one transport member is provided for one resin container, which makes the apparatus large and expensive.

In contrast, in the resin container manufacturing system 230 according to the present embodiment, a plurality of resin containers 8 are held by one container holding member 5a (5b, 5c, 5d) at a time. For this reason, as compared with the rotary type, it is possible to greatly reduce the risk of failure of the rotating mechanism and to reduce the cost of the apparatus.

In the resin container manufacturing system 230 described above, the number and pitch (mold pitch) of the resin containers 8 of the take-out stage 245, the number of

container holding holes

9a, 9b, 9c, and 9d at the container supply position P1 and the number thereof. When the pitch is different, the robot arm 250 may be configured to adjust the difference in pitch and number.

In the above embodiment, the number of container holding members arranged on the turntable 3, that is, the number of other processes performed in parallel with the coating process, is not limited to the above example, and the cleaning process is omitted. Five or more processes may be added by adding a process or other process. As a result, the mass production efficiency can be further improved.

In addition, the number of coating treatments is not limited to one, and the coating treatment may be performed twice. That is, two coating processing steps may be provided. In that case, the same coating process may be performed twice, or a film different from the first may be formed in the second coating process.

While the present invention has been described in detail and with reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.

For example, in the above-described example, the configuration including the drive mechanism that rotationally drives the turntable 3 has been described, but the configuration is not limited thereto. For example, the present invention can be applied to a configuration including a transport mechanism (such as a belt conveyor) including a transport table instead of a rotation mechanism including a rotary table.

Although the present invention has been described in detail and with reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.
