Description

  TECHNICAL FIELD The present invention relates to an apparatus for sealing a packaging container made of a synthetic resin sheet material composed of a container body and a lid, such as a beet packaging container or an egg packaging container. More specifically, even if the container main body and the lid are individually formed, the container main body and the lid are integrally connected via a hinge portion on one side thereof. The present invention also relates to a sealing device for a packaging container that can be sealed.

  Thus, the present invention relates to a sealing device suitable for a producer of a packaged product to efficiently package and seal the product using a power source in a production factory or packaging warehouse for the product. .

Conventionally, in this type of synthetic resin sheet packaging container, the container body and the lid are separately formed, and the container body and the lid are integrated on one side via a hinge portion. There are generally connected containers, both of which are generally well known. Most of the packaging forms in which required products are sold in the container are usually efficiently performed by an automatic sealing device in a factory or the like. For example, in the case of a chicken egg packaging container, it is possible for egg producers to store the required number of eggs in the container, close the lid and then efficiently seal the polymer peripheral edge of the container body and lid with adhesive tape. Has been done. Such an automatic sealing device has been already proposed by, for example, the present applicant. This is described in Patent Document 1 described later, and a tape drum formed by winding a long adhesive tape into a drum shape is as described in Patent Document 2.
Japanese Patent No. 2537461 Japanese Patent No. 2995467

  Among these, the automatic sealing device described in Patent Document 1 is installed at the end part of a series of automatic egg packaging lines installed by an egg producer in its own factory, for example, 50 to 60 containers per minute. It is an automatic sealing machine that automatically seals. Eggs sealed by such an automatic sealing machine are stored in a cardboard box and packed, then shipped to the market, displayed at the store, and sold. In the former Patent Document 1, what is shown as a reel of the adhesive tape is a lump of adhesive tape for container sealing described in the latter Patent Document 2. In the present invention, this lump of tape is called a tape drum.

  As described above, such a sealing device currently used has a structure that operates efficiently and efficiently as described above. However, a long adhesive tape used for sealing is wound around the device. The installation place of the formed tape drum has a problem. This tape drum is formed by winding an adhesive tape in several layers while appropriately shifting the width in the width direction like a thread winding, for example, having a width of about 400 to 500 mm and a diameter of about 500 to 600 mm. . The most demanding tape length is 10,000 m.

  The need for this long tape prevents the machine from having to perform additional tape changes during the day's work, and forces the machine to stop during the tape change. This is to avoid the inconvenience that is caused as much as possible.

  On the other hand, in the current container sealing device, as shown by the phantom line L60 in the plan view of FIG. 2, a cylindrical tape holder for mounting a tape drum on the back surface of the control box B in the sealing device A L9 is installed with the mounting side of the tape drum L60 facing the back side of the sealing device A. That is, the tape drum L60 is inserted into the tape holder L9 from the back side of the sealing device A and attached.

  However, the tape drum L60 in which a long adhesive tape is wound, for example, has a considerable size and mass of about 350 mm in diameter, about 300 mm in width, and about 8 to 10 kg in weight in the 10,000 mm winding drum. In order to insert and mount the tape holder L9 protruding from the back side of the sealing device from the back side of the machine, the end of the holder L9 is attached to the back side direction of the machine. In addition, a space equal to or larger than the width of the tape drum D and a work space required for the mounting operator to be mounted must be kept at all times. When this space is too small, there is a problem that the replacement work of the tape drum is troublesome and takes time.

  On the other hand, this container sealing device A is rarely installed in a spacious place in the factory, and is installed with a large space on the back side of the device only for exchanging tape drums. Usually, it is installed as close to the wall surface as possible, or as close to other mechanical devices as possible. Therefore, the replacement work of the tape drum is a troublesome and time-consuming factor. Thus, having to secure a large space on the back side of the apparatus has a problem to be solved that the factory space cannot be effectively used.

  The present invention has been achieved for the purpose of solving such problems of the conventional apparatus, and at least a space for replacing the tape drum is secured on the back side of the sealing apparatus. The tape drum is structured so that the tape drum can be exchanged from the front side of the sealing device or the longitudinal outer side of the sealing device, which is not necessary and always has the necessary space for machine operation. It is possible to provide a container sealing device having a structure in which the entire sealing device can be installed in a state of being close to a wall surface or the like in the factory.

Has an effect.

  In the following, an embodiment of a packaging container sealing device according to the present invention will be described with reference to the drawings. 1 to 6 are views showing a first embodiment, wherein FIG. 1 is a front view showing a schematic front structure of the entire apparatus, FIG. 2 is a plan view showing the same planar structure, and FIG. 3 is a tape drum mounting means. FIG. 4 is a perspective view illustrating a sealing portion, and FIGS. 5 and 6 are partially longitudinal front views illustrating a pressure roller portion.

  The sealing device A shown in this embodiment is a portion biased to the left side of the entire device as seen in FIGS. 1 and 2, and as seen in FIGS. 2 and 3, on the back side of the entire device. The tape drum 60 has a structure in which almost the whole is positioned on the back side of the container transport conveyor 5. Reference numeral B shown in FIGS. 1 to 3 is a control box having various switch buttons B1 on the upper surface and a control operation lever B2 on the front surface.

  Further, as shown in FIG. 4, the container C sealed by the container sealing device A has the container main body 1 and the lid body 2 integrally connected via a hinge portion 3 at one side edge portion thereof. A thin packaging container made of a synthetic resin sheet, which is a generally known egg packaging container. Needless to say, this container C does not exclude a container made of a foamable resin sheet. Therefore, the distance between the pressing rollers 10 and 10 arranged opposite to each other in the vertical direction so as to correspond to the container having the thickness of the foamable resin material is the pressing force of the spring 46 shown in FIGS. 5 and 6 to be described later. Against this, it can be expanded as necessary.

  Thus, the synthetic resin packaging container C shown in the embodiment is intended for the container in which the container body 1 and the lid body 2 are integrally formed by the hinge portion 3 as described above. Therefore, as shown in FIG. 4, the sealing operation may be performed by sandwiching only the overlapping peripheral edge 4 on the free end side of the container body 1 and the lid body 2 with the adhesive tape 6 from above and below.

  This sealing device A includes a conveyor 5 for transporting a packaging container C containing products, and a polymerization peripheral edge portion on the free end side of the container body 1 and the lid body 2 on the side facing the hinge portion 3 of the container C. 4 is provided with a sealing mechanism 7 for sealing 4 with an adhesive tape 6 and a cutter mechanism 8 for cutting the adhesive tape 6 after sealing the packaging container C at a predetermined position.

  Further, as shown in an enlarged view in FIG. 4, the sealing mechanism 7 includes a pair of upper and lower pressure rollers 10 for adhering the peripheral edge portion 4 of the container C in a folded manner with the adhesive tape 6 while feeding the adhesive tape 6. 10 and a guide jig 12 which is arranged along the feeding direction of the container C and guides the polymerization peripheral edge 4 of the container C, and the adhesive tape 6 is bent in a V-shaped cross section in order to sandwich the peripheral edge 4 of the container The guide member 14 is provided with a V-shaped guide portion 14 a that can be fed between the pressure-bonding rollers 10 and 10, and the guide roller 13 that feeds the adhesive tape 6 into the guide member 14. The sealing mechanism 7 including the pair of pressure rollers 10 and 10 is held by a frame 21 of the sealing device.

  The guide member 14 shown in the embodiment is formed of a flat metal plate material having an appropriate thickness, and has a structure in which a V-shaped guide portion 14a is formed on a vertical end surface facing the direction of the conveyor 5, and the pressure bonding is performed. It is attached to the frame 21 in a state of being close to the rollers 10 and 10.

  1 and 4, the guide jig 12 for guiding the overlapping peripheral edge 4 of the container is provided with a pair of plate members 12 a and 12 b disposed vertically opposite to each other with a horizontal gap 11 therebetween. It is attached to the vertically arranged back plate 12c. As a result, the gap 11 constitutes a substantially bottomed U-shaped groove. Further, the guide jig 12 including the plate members 12a and 12b arranged on the upper and lower sides includes a container receiving wide guide portion on the start end side on the container feed direction side, and the container feed direction end side has a narrower vertical width toward the tip end. Thus, the adhesive tape 6 is not prevented from being bent into a V shape by the guide portion 14a at the front portion of the guide jig 12.

  Thus, the container transporting conveyor 5 in the sealing device A shown in the embodiment is configured such that the tape drum 60 is moved from the front side of the conveyor 5 to the rear side on the container transport starting end side a (left side in FIGS. 1 and 2). A lower space S that moves toward the side is provided. Further, as shown in FIG. 3, the tape holder 9 shown in this embodiment is a horizontal plate 92 that protrudes from the substrate 91 fixed to the back side of the rear frame 5 a of the conveyor 5 toward the back side of the conveyor 5. The conveyor 5 moves so that the base end portion is fixed to the holder fixing portion 90 formed in an L shape in a side view and the tip end portion projects downward from the conveyor 5. It is arranged in a posture that intersects the direction.

  As shown in FIG. 3, the tape drum 60 is inserted into the tape holder 9 from the front side of the conveyor 5 through the lower space S of the conveyor 5 so as to contact the holder fixing portion 90. In this way, the tape drum 60 is installed on the back side of the conveyor 5.

  The leading end of the adhesive tape 6 is taken out from the tape drum 60 arranged in this way as shown in FIG. 2 and guided from the reversing roller 15 via the tape guide bar 16 arranged horizontally on the top of the tape drum 60. It is configured to be transferred toward the guide member 14 and the pressure rollers 10 and 10 through the roller 13.

  As shown in FIG. 2, the cutter mechanism 8 includes a cutter blade 81 fixed to a conveyor-side end of a moving shaft 82 that is pivotally supported so as to be movable in the front-rear direction on a fixed base 84 supported by the frame 21. The operation piece 83 operated by an operation lever (not shown) is moved in the front-rear direction by the movement in the front-rear direction, and is arranged so that the tape cutting portion on the rear side where the container is sealed is located within the movement range.

  In the sealing device A thus configured, as shown in FIG. 4, the overlapping peripheral edge portion 4 on the free end side of the container C containing the food is moved in the direction of the arrow while being sandwiched between the grooves of the guide jig 12, that is, the gap 11. Then, the peripheral edge 4 is sandwiched between the pressure rollers 10 and 10 together with the pressure-sensitive adhesive tape 6 formed in a V shape at a position before the pressure rollers 10 and 10, and bonded and sealed. At this time, the rotational speed is adjusted so that the tape feeding speed of the pressure roller 10 and the container feeding speed of the conveyor 5 are synchronized. In this way, the container C is sealed with the adhesive tape 6. Further, the double-folded tape connected to the rear of the sealed container is cut by the cutter blade 81 at an appropriate position from the rear end of the container, and the tape at the rear of the container C is cut off.

  In order to initially set the tip of the adhesive tape 6 to the two upper and lower pressure-bonding rollers 10, 10, it is preferable to move the upper pressure-bonding roller upward so that a gap is formed between the two rollers. Therefore, in this embodiment, as shown in FIG. 5, the upper frame 40 that supports the upper pressure roller 10 is moved upward and separated from the frame 21 that supports the lower pressure roller 10. This separation is achieved by holding the upper frame 40 in a seesaw-like manner with the pivot 45 fixed to the frame 21 as a fulcrum, and at the end of the upper frame 40 opposite to the side where the fixed upper roller is provided, A spring 46 that always pushes the end upward is provided, and the tip of a rod rod 47 extended from the lower frame 21 is loosely passed through the upper surface of the upper frame 40, and the exposed portion swings around the pin shaft 48 as a fulcrum. The cam 49 is provided and operated by the operation lever 50.

  In this manner, as shown in FIG. 6, the operation lever 50 is pushed down to rotate the cam 49, whereby the upper frame 40 swings around the pivot 45, and the upper roller 10 is lifted to contact the lower roller. A gap is formed between them. In this way, the tape may be sandwiched between the upper and lower rollers that form the gap.

  The second embodiment shown in FIGS. 7 to 9 will be described below. FIG. 7 is an overall front view showing a state where a drum is installed, FIG. 8 is an overall plan view thereof, and FIG. 9 is an overall front view showing a state before the drum is mounted.

  The container transfer conveyor 5 shown in the second embodiment has a structure in which a tape holder 9 is arranged on the container transfer start end side a as in the case of the first embodiment. The tape drum 60 is provided with a side space T that is sufficient to put in and out the tape drum 60, and the tape holder 9 is installed in the side space below the conveyor 5. Specifically, the support board 93 spanned on the lower surfaces of the front and rear frames 5a and 5b of the conveyor 5 is horizontally horizontal with respect to a turntable 94 installed downwards in a circumferential direction. A rotating plate 95 is attached, and a holder fixing portion 90 is formed so as to hang from the left end of the conveyor as shown in FIG. A tape holder 9 is provided so that the base end portion is fixed in a form along the longitudinal direction of the conveyor 5 and the distal end portion extends toward the left outer end side of the conveyor 5.

  A tape drum 60 is inserted and suspended from the left outer end of the conveyor 5 until it comes into contact with the holder fixing portion 90 with respect to the tape holder 9. Thereafter, the horizontal rotating plate 95 is rotated toward the back side of the conveyor 5 with the rotary table 94 as a rotation axis until it contacts the rotation stopper 96, and the tape drum 60 is moved to the back side of the conveyor 5 as shown in FIG. It is always installed at a predetermined location on the side.

  The tape holder 9 shown in the embodiment is arranged in a posture along the moving direction of the conveyor 5 as an insertion of the tape drum 60 from the left outer side of the conveyor 5. The tape holder 9 is the same as that of the first embodiment. Like the tape holder 9, the tape drum 60 is inserted from the front side of the conveyor 5 by being arranged in a posture intersecting with the moving direction of the conveyor 5, and is rotated using the rotary table 94 and the horizontal rotating plate 95. By doing so, the tape drum 60 can be used as it is as a structure in which the tape drum 60 is arranged on the back side of the conveyor 5.

  Next, the third embodiment shown in FIGS. 10 to 12 will be described. FIG. 10 is an overall front view for explaining a sealing device of a third embodiment, and FIGS. 11 and 12 are central longitudinal side views showing a cart structure used in the embodiment.

  The container conveying conveyor 5 of the sealing device shown in the third embodiment has a structure in which a tape holder 9 is arranged on the container conveying start end side a as in the case of the first embodiment. The tape holder 9 has two rails 98 installed on the upper surface of the frame 97 extending from the front side to the back side of the conveyor 5 in the lower space S formed in the front-rear direction below the left side portion of the conveyor 5. A moving carriage 99 with rollers on the rail 98 has a holder fixing portion 90 erected at the rear end, and the tape holder 9 that suspends the tape drum 60 on the front side of the holder fixing portion 90 is moved in the moving direction of the conveyor 5. It is assumed that it is installed in the direction that intersects.

  Thus, the tape drum 60 is inserted and suspended from the front side of the conveyor 5 with respect to the tape holder 9 until it comes into contact with the rear holder fixing portion 90, and then the movable carriage 99 is moved to the back side of the conveyor 5. Then, it is pushed in and fixed until it comes into contact with the stopper wall 100 erected at the rear end of the frame 97. In this way, the tape drum 60 can be installed at a predetermined location on the back side of the conveyor 5.

  The holder 9 of the tape drum 60 shown in FIG. 11 is formed not by a cylinder but by a rod shaft, and a spring-loaded ball elastic latch 18a for fixing the axial movement of the tape drum 60 is provided on the rod shaft. The tape drum 60 can be inserted into and removed from the tape holder 9 by one-touch operation by strongly pushing and pulling.

  Further, the holder 9 of the tape drum 60 shown in FIG. 12 is threaded at the tip of the rod shaft to form a bolt portion 18b. After the tape drum 60 is suspended, a nut 18c is screwed into the bolt portion 18b. It is structured to fix the position in the axial direction by tightening and tightening. Needless to say, the tape drum 60 needs to be rotatable between the tape holder 9 and whether the tape holder 9 itself is rotatable.

  In each of the above-described embodiments, the tape holder 9 is shown as a structure in the case where the tape holder 9 is disposed on the container conveyance start end side a (the left side in FIGS. 1 and 2) of the conveyor 5. It is assumed that the tape drum 60 is disposed on the back surface of the container conveyance end side b, and is arranged on the right side in FIGS. Moreover, in each said Example, although the installation direction of the tape holder 9 was shown as what was formed in the direction which cross | intersects the moving direction of the conveyor 5 in the back side of the conveyor 5, the axial direction of this tape holder 9 is shown. By arranging the tape pull-out guide bar and the tape reversing roller as appropriate, it is possible to carry out by arranging in a posture along the moving direction of the conveyor 5, an intermediate angle thereof, or a posture having an appropriate inclination angle. It doesn't require many words about what can be done.

  The representative embodiments of the present invention have been described above. However, the present invention is not necessarily limited to the structures of the embodiments described above, and has the configuration of the present invention and achieves the above-described object and has an effect. In the range which is, it can change suitably and can implement.

  In the sealing device according to the present invention, it is possible to effectively use the installation location in the factory or the like without taking an extra space when installing the device, and the time required for the replacement and supply work of the tape drum. Therefore, it is expected to be widely spread and used.
