Description

  The present invention relates to a container sealing device.

  A portion pack in which a liquid or gel-like body is used as a content and is sealed in a molded container is manufactured by sealing an opening of a container containing the content with a sealing material. And the sealing apparatus which joins a sealing material to the opening part of a some container sequentially, and seals these containers sequentially is known. In such a sealing device, the container is typically transferred intermittently along the transfer path. Moreover, the sealing material is long and wound around a roll, and is sent along the transfer path by being wound around another roll. And a sealing material is joined to the opening part of a container in the area between both rolls, and the joined part of the sealing material joined after that is isolate | separated.

  In the sealing device as described above, the feeding of the sealing material is controlled by the rotation of both rolls. Therefore, in order to synchronize the feeding of the sealing material with the feeding of the container, it is necessary to change the rotational speeds of both rolls from moment to moment, which is not easy. If the sealant is not synchronized with the container transfer until the sealant is joined to the opening of the container and the joint is separated, the position of the sealant and the joint of the sealant In some cases, the sealing of the opening of the container may be incomplete due to peeling.

  In the sealing device described in Patent Document 1, a container is placed in a section between a joining unit that joins the sealing material to the opening of the container and a cutting unit that cuts out a joining portion of the sealing material in the container transfer path. A pair of gripping bodies to be gripped are provided, and these gripping bodies are reciprocated along the transfer path to transfer the container. These gripping bodies grip the sealing material together with the container, and feed the sealing material integrally with the container. According to such a configuration, the seal material is prevented from being synchronized with the transport of the container until the seal material is joined to the opening of the container and the joined portion is separated.

  However, there may be a case where the containers are spaced so that the next container does not reach the joining means when the sealing of one container is completed. For example, the container may be manually supplied to the sealing device, and there may be a gap because the supply is not in time. In addition, another member such as an opening tool that breaks the sealing material that seals the opening and opens the portion pack may be formed integrally with the container, and may have to be spaced apart. In such a case, if the transfer means for transferring the container as in the sealing device described in Patent Document 1 also serves to feed the sealing material, the sealing material will be wasted.

JP-A-61-47310

  The present invention has been made in view of the above-described circumstances, and the sealing of the opening of the container with the sealing material is reliably performed by synchronizing the transfer of the container and the feeding of the sealing material, and saves the sealing material.

  1 and 2 show an example of a container.

  The container 1 includes a container body 2 and a first seal member 3.

  The container body 2 has a cylindrical shape, one end is open, and the other end is provided with a bottom 4. An opening 5 is formed in a part of the bottom 4. In the illustrated example, the container body 2 has a substantially rectangular cylindrical shape in plan view, and the openings 5 are provided at four corners of the bottom 4, respectively. These openings 5 serve as injection ports when the fluid is injected into the container 1. In some cases, some of the openings 5 are used as inlets, and the remaining openings 5 are used as exhaust ports for exhausting air in the container when the fluid is injected into the container 1.

  Further, a plurality of annular ribs 6 are formed on the outer surface 4 a of the bottom 4. Each of these ribs 6 is provided so as to surround the outside of the opening 5, and is spaced from the edge of the outer surface 4 a of the bottom 4 over the entire circumference thereof.

  The first seal member 3 is joined to the end surface 7 a of the open end 7 of the container body 2 and seals the open end 7. The first seal member 3 is a film made of a thermoplastic resin, and the first seal member 3 is joined to the end surface 7a of the open end 7 by welding. The joining of the first seal member 3 and the end surface 7a of the open end 7 is not limited to welding. For example, an adhesive may be applied to the end surface 7a of the open end 7, and the first seal member 3 and the end surface 7a of the open end 7 may be joined by the adhesive. Therefore, the first seal member 3 is also welded. It is not limited to what is possible.

  FIG. 3 shows an example of a portion pack in which a fluid 12 is sealed in a container 1.

  The portion pack 10 is configured such that the second seal member 11 is joined to the outer surface 4a of the bottom 4 of the container 1 into which the fluid 12 has been injected, and the opening 5 of the bottom 4 is sealed. The fluid 12 is injected into the container 1 so as to substantially fill the capacity of the container 1 and is enclosed in the container 1.

  The second seal member 11 is a film made of a thermoplastic resin, and is joined to the outer surface 4a of the bottom 4 of the container 1 by welding. The joining of the second seal member 11 and the outer surface 4a of the bottom 4 is not limited to welding. For example, an adhesive may be applied to the outer surface 4a of the bottom 4, and the second seal member 11 and the outer surface 4a of the bottom 4 may be joined by the adhesive. Therefore, the second seal member 11 can also be welded. It is not limited to things.

  FIG. 4 shows a manufacturing process of the portion pack 10.

  The fluid 12 is injected into the container 1 whose open end 7 is sealed with the first seal member 3 through the opening 5 formed in the bottom 4 thereof. A substantially constant amount of the fluid 12 is injected using, for example, a dispenser. Due to the surface tension of the fluid 12, the shape of the surface of the fluid 12 injected into the container 1 is a concave shape in which the edge portion 12a contacting the inner surface of the side wall of the container 1 is raised compared to the central portion 12b. Present. (FIG. 4A)

  When the surface edge 12 a of the fluid 12 reaches the inner surface 4 b of the bottom 4 of the container 1, the surface edge 12 a of the fluid 12 is pressed against the inner surface 4 b of the bottom 4, and the fluid 12 is injected by further injection of the fluid 12. Stay in position. On the other hand, a space is left between the surface center portion 12 b of the fluid 12 and the inner surface 4 b of the bottom 4, and the surface center portion 12 b gradually bulges as the fluid 12 is further injected. Contact 4b. That is, the surface of the fluid 12 having a concave shape is leveled by the inner surface 4 b of the bottom 4. Thereby, the fluid 12 is filled in the container 1. (FIG. 4B to FIG. 4C)

  The second seal member 11 is joined to the outer surface 4 a of the bottom 4. All the openings 5 in the bottom 4 are sealed by the second seal member 11, and the fluid 12 is sealed in the container 1. (FIG. 4D)

  FIG. 5 shows in detail the joining state of the container 1 and the second seal member 11 around the opening 5.

  Due to variations in the injection amount of the fluid 12 by the dispenser, the fluid 12 may extend over the periphery of the opening 5 on the outer surface 4 a of the bottom 4 beyond the edge of the opening 5. The figure shows a state in which the fluid 12 is spread around the opening 5.

  The second seal member 11 is joined to the outer surface 4 a of the bottom 4 in a state where the fluid 12 is wet and spread around the opening 5. Since the outer surface 4a of the bottom 4 is larger than the end surface when the end of the container 1 provided with the bottom 4 is an open end, even if the fluid 12 spreads around the opening 5, the outer surface 4a A bonding region can be provided on the outer surface 4 a of the bottom 4 so as to surround the opening 5.

  In particular, a plurality of annular ribs 6 are formed on the outer surface 4 a of the bottom 4, and each of these ribs 6 is provided so as to surround the outside of the opening 5. Each of the ribs 6 is spaced from the edge of the outer surface 4a of the bottom 4 over the entire circumference. The wetting and spreading of the fluid 12 is blocked by the rib 6, and a joining region surrounding the opening 5 is secured outside thereof.

  As described above, when the second seal member 11 is joined to the outer surface 4 a of the bottom 4, each of the openings 5 is surrounded by a joint portion between the second seal member 11 and the outer surface 4 a of the bottom 4. Thereby, the opening 5 is reliably sealed by the second seal member 11.

  FIG. 6 shows an example of an opening tool for the above-described portion pack 10 and a step of opening the portion pack 10 using this opening tool.

  The opening tool 20 includes a substrate portion 21, a convex portion 22 provided at the center of the upper surface of the substrate portion 21, and a sharp claw portion 23 protruding from a part of the edge of the upper surface of the convex portion 22. ing. The convex portion 22 can be inserted into the container 1 from the open end 7 side of the container 1 of the portion pack 10 and is loosely fitted inside the container 1.

  The first seal member 3 that seals the open end 7 of the container 1 of the portion pack 10 is pressed against the convex portion 22 of the opening tool 20, and the first seal member 3 is perforated by the claw portion 23 on the upper surface of the convex portion 22. . (FIG. 6A)

  The first seal member 3 is further pressed against the convex portion 22 of the opening tool 20, the first seal member 3 is broken with the hole generated by the claw portion 23 as a base point, and the portion pack 10 is opened. Then, the convex portion 22 is inserted into the container 1. The fluid sealed in the portion pack 10 is pushed out by the convex portion 22. The fluid to be pushed out is received by the substrate part 21 and recovered. (FIG. 6B)

  When the convex portion 22 is completely inserted into the container 1, the inside of the container 1 is replaced with the convex portion 22, whereby substantially all of the fluid sealed in the portion pack 10 can be recovered. (FIG. 6C)

  7 and 8 show an example of a container sealing device that seals the opening 5 of the container 1.

  The sealing device 100 joins the second seal member 11 to the outer surface of the bottom 4 of the container 1 to seal the opening 5 of the container 1. A plurality of containers 1 are arranged on the pallet 108, and the containers 1 are supplied to the sealing device 100 in units of pallets. In the drawing, for simplicity, only one container 1 is shown for each pallet 108.

  The sealing device 100 is supplied from a transfer unit 101 that transfers the pallet 108 on which the container 1 is arranged, a supply unit 102 that supplies a sealing material 120 that is a material of the second seal member 11, and a supply unit 102. The sealing means 120 for feeding the sealing material 120, the injection means 104 for injecting the fluid into the container 1, the joining means 105 for joining the sealing material 120 to the container 1 of the pallet 108, and the container 1 of the pallet 108. A cutting means 106 for cutting out the joining portion (second seal member 11) from the sealing material 120 and a separating means 107 for separating the cut-out joining portion (second sealing member 11) from the remaining sealing material 120 are provided. .

  The transfer means 101 includes a guide rail 110 extending along the transfer path of the pallet 108, an engagement member 111 detachably engaged with the plurality of pallets 108 mounted on the guide rail 110, and an engagement member 111. And a driving mechanism 112 for driving the motor.

  The engaging member 111 includes a base 113 that extends under the guide rail 110 and extends in parallel with the guide rail 110, and a plurality of pins 114 that are erected on the base 113 at a predetermined pitch.

  The drive mechanism 112 supports the engagement member 111, and a lift drive mechanism 115 such as a cylinder piston that lifts and lowers the engagement member 111, and a translation drive such as a linear motor that reciprocates the lift drive mechanism 115 along the transfer path of the pallet 108. Mechanism 116.

  The engaging member 111 is driven by the elevating drive mechanism 115 and the engaging member 111 engages the pins 114 with the plurality of pallets 108 placed on the guide rail 110. Next, the elevating drive mechanism 115 and the engaging member 111 supported by the elevating driving mechanism 115 are advanced along the transfer path by being driven by the translation drive mechanism 116, and the plurality of pallets 108 with which the pins 114 are engaged are the engaging members. 111 and the guide rail 110 are advanced together. Next, the engaging member 111 is driven by the lifting drive mechanism 115 to lower, and the engaging member 111 engages and disengages the pins 114 from the plurality of pallets 108. Next, the lift drive mechanism 115 and the engagement member 111 supported by the lift drive mechanism 115 driven by the translation drive mechanism 116 retreat along the transfer path, and the engagement member 111 returns to the initial position. By repeating the above cycle, the plurality of pallets 108 are intermittently transferred along the transfer path.

  The sealing material 120 is a long film made of a thermoplastic resin, and the supply unit 102 includes an original fabric roll 121 around which the sealing material 120 is wound, and a winding roll 122 that winds the sealing material 120 from the original fabric roll 121. And a plurality of auxiliary rolls 123.

  The original fabric roll 121 and the take-up roll 122 are each driven by a motor (not shown). This is not for controlling the feeding of the sealing material 120 but for removing a slack of the sealing material 120 by applying a certain tension to the sealing material 120.

  The plurality of auxiliary rolls 123 are appropriately disposed in a section between the raw fabric roll 121 and the take-up roll 122 and define the feed path of the sealing material 120. The feeding path of the sealing material 120 is along the transfer path of the pallet 108 in a part of the section, and the sealing material 120 overlaps the outer surface of the bottom 4 of the container 1 of the pallet 108 in the section.

  The injection means 104 is disposed upstream of the section along the transfer path of the pallet 108 along the feed path of the sealing material 120. The injection means 104 includes a dispenser 140 and a sensor (not shown). When the pallet 108 to be transferred is placed under the injection means 104, the injection means 104 detects this with a sensor, operates the dispenser 140 based on the detection signal of the sensor, Fluid 12 is injected.

  The joining means 105 is arranged in a section along the feed path of the sealing material 120 in the transport path of the pallet 108. The joining means 105 includes a heat welding head 150 that is driven up and down and a sensor (not shown).

  When the pallet 108 to be transferred is arranged under the joining means 105, the joining means 105 detects this by a sensor and lowers the thermal welding head 150 based on the detection signal of the sensor. The sealing material 120 is pressed against the container 1 of the pallet 108 by the descending heat welding head 150 and is welded to the outer surface of the bottom 4 of the container 1. Thereby, the container 1 is sealed in the opening 5. In addition, joining of the sealing material 120 and the outer surface of the bottom 4 is not limited to welding. For example, an adhesive may be applied to the outer surface of the bottom 4 and the sealing material 120 and the outer surface of the bottom 4 may be joined by the adhesive. In that case, for example, an adhesive is applied to the outer surface of the bottom 4 of the container 1 upstream of a section along the transfer path of the pallet 108 along the feed path of the sealing material 120.

  The cutout means 106 is disposed on the downstream side of the joining means 105 in a section along the feed path of the sealing material 120 in the transfer path of the pallet 108. The cutout means 106 includes a laser marker 160 and a sensor (not shown).

  When the pallet 108 to be transferred is placed under the cutout means 106, the cutout means 106 detects this with a sensor and operates the laser marker 160 based on the detection signal of the sensor. The laser marker 160 irradiates the sealing material 120 welded to the container 1 of the pallet 108 with a laser. The laser is irradiated along the edge of the outer surface of the bottom 4 of the container 1. Accordingly, the second seal member 11 is cut out from the seal material 120 in a state where the second seal member 11 is bonded to the outer surface of the bottom 4 of the container 1. The pallet may be a die, and a punch may be pressed against the die to punch out the second seal member 11 from the seal material 120.

  The separating means 107 is disposed on the downstream side of the cutting means 106, and defines the downstream end of the section along the transfer path of the pallet 108 in the feed path of the sealing material 120. Separating means 107 includes a spatula-like slidable contact member 170 that is in sliding contact with seal material 120, and a roller 171 that guides seal material 120 upward downstream of slidable contact member 170.

  The sealing material 120 is bent immediately after the sliding contact member 170 and is sent upward to be separated from the transfer path. However, the second sealing member 11 cut out from the sealing material 120 is joined to the container 1 and is connected to the pallet 108. Move along the transfer path. Thereby, relative movement occurs between the second seal member 11 and the remaining sealing material 120, and the second seal member 11 is separated from the remaining sealing material 120.

  The feeding means 103 is arranged in a section between the joining means 105 and the cutout means 106 in the transfer path of the pallet 108. The feeding means 103 includes a pair of gripping mechanisms 130 which are provided on both sides of the sealing material 120 and each grips and releases the edge of the sealing material 120. These gripping mechanisms 130 are fastened to the lifting / lowering driving mechanism 115 reciprocally driven along the transfer path by the translation driving mechanism 116 in the transfer means 101, and move together with the lifting / lowering driving mechanism 115.

  The feeding means 103 is used when the engaging member 111 engaged with the pallet 108 and the elevating drive mechanism 115 that supports the pallet 108 are moved forward to transfer the pallet 108 in the cycle of the above-described transferring means 101 for transferring the pallet 108. In addition, the sealing material 120 is gripped by the gripping mechanism 130. As the gripping mechanism 130 moves forward integrally with the lifting drive mechanism 115, the sealing material 120 gripped by the gripping mechanism 130 is sent along its feed path. The feeding means 103 releases the gripping of the sealing material 120 by the gripping mechanism 103 when the engaging member 111 engaged / disengaged from the pallet 108 and the lifting / lowering drive mechanism 115 supporting the same retracts to return to the initial position. To do. The gripping mechanism 130 moves backward together with the lifting drive mechanism 115 and returns to the initial position. By repeating the above cycle, the sealing material 120 is intermittently fed along the feeding path. Thus, when feeding the sealing material 120, the feeding means 103 holds the sealing material 120 and moves integrally with the transfer means 101. Thereby, the sealing material 120 is joined to the container 1 of the pallet 108, and the feeding of the sealing material 120 and the feeding of the pallet 108 are easily synchronized until the joining portion (second sealing member 11) is separated. Can take.

  The feeding means 103 holds the sealing material 120 in the section between the joining means 105 and the cutting means 106 in the pallet 108 transfer path, and the sealing material 120 in the section between the joining means 105 and the cutting means 106. When synchronizing the feeding of the pallet 108 and the transfer of the pallet 108, it is possible to prevent the two from being out of synchronization due to the elongation of the sealing material 120.

  The pallet 108 can also be transferred using a belt conveyor, but since the belt circulates and returns to the initial position, a plurality of pallets 108 can be transferred without interruption, and the sealant 120 can be sent in synchronization therewith. A plurality of gripping mechanisms 130 of the feeding means 103 are required along the belt. On the other hand, the transfer means 101 transfers the pallet 108 by reciprocatingly driving the engaging member 111 detachably engaged with the pallet 108 and the elevating drive mechanism 115 supporting the engaging member 111 along the transfer path. As described above, one set of gripping mechanisms 130 is sufficient, and the configuration of the apparatus can be simplified.

  The feeding unit 103 grips the sealing material 120 by the gripping mechanism 130 only when the pallet 108 is in the section between the joining unit 105 and the cutout unit 106 in the transport path of the pallet 108. Whether or not the pallet 108 is in the section between the joining means 105 and the cutout means 106 is determined by, for example, using a sensor provided in each of the joining means 105 and the cutout means 106 and passing through the joining means 105. And the number of pallets that have passed through the cutting means 106 are counted and compared.

  FIG. 9 shows a step of sequentially sealing a plurality of containers 1 using the container sealing device 100 configured as described above.

  FIG. 9 shows a state in which the interval between two pallets 108a and 108b among the plurality of pallets to be transferred is large, and the interval P is cut out from the joining means 105 along the transfer path of the pallet 108. It is larger than the distance L to 106. Such a state may occur, for example, when the supply of the pallet 108 to the container sealing device 100 is performed manually. In the figure, only two pallets 108a and 108b with a gap P are shown for simplicity.

  The preceding pallet 108a is disposed under the joining means 105, and the sealing material 120 is welded to the container 1 of the pallet 108a. Thereby, the container 1 is sealed in the opening 5. (FIG. 9A)

  Next, the pallets 108a and 108b are transferred by the transfer means 101 that operates in the above-described cycle. Here, a pallet 108 a is provided in a section between the joining unit 105 and the cutout unit 106 in the transfer path of the pallet 108. Therefore, the feeding means 103 moves the engaging member 111 engaged with the pallet 108 and the elevating drive mechanism 115 supporting the pallet 108 in the cycle of the transferring means 101 for transferring the pallet 108 to transfer the pallet 108. When doing so, the sealing material 120 is gripped by the gripping mechanism 130. As the gripping mechanism 130 moves forward integrally with the lifting drive mechanism 115, the sealing material 120 gripped by the gripping mechanism 130 is sent along its feed path. Since the gripping mechanism 130 that grips the sealing material 120 moves integrally with the lifting drive mechanism 115 that transports the pallet 108a, the feeding of the sealing material 120 is reliably synchronized with the transport of the pallet 108a. Thereby, it is prevented that peeling occurs in the joining between the container 1 of the pallet 108a and the sealing material 120. (FIG. 9B)

  The transfer means 101 repeats the above cycle, and the preceding pallet 108a is placed under the cutout means 106. The second sealing member 11 is cut out from the sealing material 120 in a state where the second sealing member 11 is welded to the container 1 of the pallet 108a. Thereby, sealing of the container 1 of the pallet 108a is completed. Here, the interval P between the pallets 108 a and 108 b is larger than the distance L from the joining means 105 to the cutout means 106 along the transfer path of the pallet 108. Therefore, when the preceding pallet 108a is disposed below the cutout means 106, the subsequent pallet 108b is positioned upstream of the joining means 105 along the transfer path. (FIG. 9C)

  As the transfer means 101 repeats the above cycle, the pallet 108b is transferred under the joining means 105. Meanwhile, the section between the joining means 105 and the cutout means 106 in the transfer path of the pallet 108 has a pallet. Does not exist. Therefore, the feeding means 103 moves the engaging member 111 engaged with the pallet 108 and the elevating drive mechanism 115 supporting the pallet 108 in the cycle of the transferring means 101 for transferring the pallet 108 to transfer the pallet 108. In doing so, the sealing material 120 is released without gripping the sealing material 120 by the gripping mechanism 130. Even if the gripping mechanism 130 moves forward integrally with the lifting / lowering driving mechanism 115, the sealing material 120 is not sent along the feeding path, and only the pallets 108a and 108b are transferred. Thereby, the sealing material 120 is saved. (FIG. 9D)
