It is about.

  Especially, it is placed in food packaging places and stores such as supermarkets, convenience stores, fruit and vegetable stores, fresh fish stores, Japanese and Western confectionery stores, etc. In some cases, the present invention relates to a desktop-type sealing device that is downsized so that a customer who has purchased the product at the store can seal the container that stores the product.

  Conventionally, a packaging container made of a synthetic resin sheet material in which a container main body and a lid are integrally connected via a hinge portion on one side thereof, and a container main body and a lid are formed separately. A packaging container made of a synthetic resin sheet material is known. After a required product is accommodated in these containers, the peripheral edge thereof is sealed by appropriate means. In many cases, the packaging is efficiently performed in a production factory for stored goods. For example, in the case of a container for egg wrapping, a plurality of eggs are accommodated in the container, the lid is closed, and the overlapping peripheral portion of the container body and the lid body is industrially sealed with adhesive tape in the egg producer. ing. Such an automatic sealing device for wrapping eggs has already been proposed and publicly known by, for example, the present applicant. This is as described in Patent Documents 1 and 2 below.

Japanese Patent No. 2537461 Japanese Patent No. 2729598

  Thus, the egg-sealing container sealing device currently used is arranged at the end of a series of automatic egg-packing lines installed by an egg producer in its own company, for example, 50-60 pieces per minute or It is sealed by an automatic machine that automatically seals any further containers. Eggs sealed by an automatic sealing machine are stored in a cardboard box and packed, then shipped to the market and displayed at the store.

  However, with regard to eggs, not only elderly people living alone, but also young people living alone, purchase only one, two, or three pieces of eggs that are sold separately instead of 10 eggs. In recent years, not only singles but also ordinary households, as mentioned above, side dishes such as tempura and boiled dishes, kiwi, tomatoes and other small-sized dishes In some cases, fruit vegetables and the like are purchased in a required amount according to the preference of the purchaser, and the purchaser himself puts it in a container made of a synthetic resin sheet material and takes it home. In such a case, at present, it is common to hang a rubber band prepared at the store as a means for sealing the container, and sometimes it is temporarily fixed with cellophane tape. However, these sealing means have a poor sealing effect and have a problem to be solved that the lid easily opens during carrying. However, there is not yet a method for replacing such a sealing method.

  The present invention has been developed as a means for solving such problems, and is light and small in size so that it can be used by being placed on a kitchen or a tabletop or table in a store. The present invention aims to provide a container sealing device that can be easily and easily sealed not only by store employees but also by merchandise purchasers themselves using a normal 100V power supply.

  In order to achieve the object, the present invention takes technical means as described in the first aspect. That is, the main structure of the tabletop sealing device for packaging containers according to the present invention will be described using the reference numerals of the drawings used for the description of the embodiments. For packaging made of a synthetic resin sheet material comprising a container body and a lid. A table-top-type sealing device that seals a peripheral portion of the container C that is polymerized in a closed posture with an adhesive tape, and includes a conveyor 5 that moves a container that accommodates articles and is in a closed posture. A, a sealing side frame B provided with a sealing mechanism 7 that seals the overlapping peripheral edge 4 of the container C in a closed posture with an adhesive tape 6, a motor M that drives the conveyor 5 in a predetermined direction, A rotation transmission body for transmitting the rotation of the motor M to the conveyor 5, the conveyor side frame A and the sealing side frame B are formed as independent bodies, and at least one of the both frames A and B is Elevating mechanism D When the moving mechanism D is mounted on the conveyor side frame A, the container transfer surface of the conveyor 5 is moved up and down, and when the moving mechanism D is mounted on the sealing side frame B, it is moved up and down between the pair of pressure rollers described later. The sealing mechanism 7 includes a guide member 14 that feeds the pressure-sensitive adhesive tape 6 toward the pressure roller while bending the pressure-sensitive adhesive tape 6 into a V-shaped cross section, and a polymerization peripheral edge of the container. A pair of upper and lower pressure-bonding rollers 10 and 10 to be bonded to the portion 4 in a folded shape, and a cutting blade for adhesive tape connected to either one of these frames A and B on the rear end side in the moving direction of the sealed container A cutter mechanism 8 having a body 81 is disposed, and the cutting blade body 81 of the cutter mechanism 8 is normally retracted to a non-tape-cutting portion, and is related to a photoelectric tube, a limit switch, or the like that detects the presence or absence of a container. The tape is moved to the tape cutting position by the intelligent action of the structure, and the tape is cut along with this movement, and the tape feeding speed of the pressure rollers 10 and 10 and the container feeding speed of the conveyor 5 are synchronized. The structure is linked and linked.

  In addition, the requirement described in claim 2 is that the elevating / lowering mechanism D in the apparatus described in claim 1 is mounted on the conveyor-side frame A, and moves up and down the container transfer surface of the conveyor 5, thereby superimposing peripheral edges of the containers The height position of the portion 4 is configured to match the height between the pair of upper and lower pressure-bonding rollers 10 and 10 in the sealed frame B.

  As described above, the tabletop sealing device according to the present invention is light and small in size, and can be used by being placed in a small space on a kitchen or storetop in a store or in a store. The sealer is miniaturized as described above, and is used by immediately driving the conveyor in a predetermined direction just by inserting the plug of the motor power cord end into a 100V power outlet present anywhere in a general building. It is possible to seal the container while the peripheral part of the container is sandwiched between adhesive tapes by allowing the peripheral part of the container placed on the conveyor to pass between the pair of upper and lower pressure rollers. In particular, since each drive unit is interlocked and connected so as to synchronize the tape feeding speed of the pressure roller in the sealing mechanism and the container feeding speed of the conveyor, it is possible to always reliably seal the container with the adhesive tape. .

  Also, by dividing the sealing device into a conveyor side frame and a sealing side frame, and forming these frames as independent bodies, the height of the peripheral edge that seals differently in size and shape of the container Even when the height of the overlapping peripheral part from the bottom of the container is different, the height position of the sealing mechanism relative to the conveyor and the height position of the conveyor relative to the sealing mechanism are manipulated. Therefore, there is an advantage that it can be adapted to various containers. Furthermore, since the entire device can be placed on a tabletop or small table and operated so that it is small and lightweight, it is easy to carry and saves space. There is an effect that the purchaser himself / herself can use the product according to his / her preference in the container and can be conveniently used for sealing the container.

  Thus, the up-and-down movement mechanism D shown in the embodiment is provided on the conveyor side frame A among these frame bodies A and B. The conveyor-side frame A is formed by separately forming conveyor frames 5a and 5b arranged in parallel with the conveyor 5 interposed therebetween and a base 22 arranged below the conveyor frames 5a and 5b. 5b is attached so that raising / lowering is possible by the conveyor raising / lowering mechanism 9. As shown in FIG. As shown in FIGS. 1 and 3, the elevating mechanism 9 of this embodiment is configured such that two links 24 are pivotally combined with an intersection shaft 23 as a fulcrum and the upper end side of the link 24 is connected to a conveyor frame. 5a and 5b, the lower end side is connected to the base 22, and two sets are formed at the left and right locations in the longitudinal direction of the base 22, and the intersection shafts 23 of these two sets of links 24 are connected by a horizontal bar 25, One end side (left end side in the figure) of the horizontal bar 25 is always pressed by the pressing spring 26, and the other end side (right end side) is brought into contact with the eccentric cam 27 via the operation shaft 28. The operation handle 29 is connected with the front end protruding from the front surface of the conveyor frame 5b.

  The upper and lower ends of one end side (the right side in FIG. 1) of the X-shaped link 24 are rotatably connected to the conveyor frames 5a and 5b and the base 22 by fixing pins 30 and 30, and the upper and lower ends on the opposite side are slide pins. It is made to slidably fit in the horizontal long holes 32 and 32 provided in the conveyor frames 5a and 5b and the base 22 via 31 and 31, respectively.

  In order to raise and lower the elevating mechanism 9 as described above, the operating handle 29 protruding from the front surface of the conveyor frame 5b is rotated in an appropriate direction as shown in FIG. The eccentric cam 27 is rotated, and the horizontal bar 25 is moved laterally in cooperation with the pressing force of the pressing spring 26. By operating the handle, the crossing axis 23 of the X-shaped link 24 is moved laterally to change the inclination angle of the X-shaped link 24, and the distance between the conveyor frames 5a, 5b and the base 22 is changed widely. The height is raised and lowered.

  In particular, as shown in the perspective view of FIG. 7, the sealing mechanism 7 is configured such that the sealed container C is integrally connected to the container body 1 and the lid body 2 on one side via the hinge portion 3. A packaging container C made of a synthetic resin sheet material is shown, and a structure is shown in which a polymer peripheral edge 4 that is polymerized in its closed position is sandwiched in two with an adhesive tape 6 and bonded, and arranged vertically The tape guide surface is V-shaped so that the pressure-sensitive adhesive rollers 6 and 10 are disposed close to the lower side of the pressure-feeding container 10 in the container feeding direction, and the adhesive tape 6 is fed while being sequentially bent into a V-shaped cross section. The tape guide member 14 provided with the formed tape guide groove 14a, the rotating roller 13 disposed further on the lower side thereof, the tape reel receiving base 17 disposed on the lower side thereof, and the base 17 installed on the receiving base 17 Tape reel From R pulling the tape 6, it is a tape feed roller 15 with a pressure roller 16 for transferring the rotation roller 13 is disposed on the component placement plate 20.

  The tape guide member 14 and the pressure rollers 10 and 10 are preferably as close as possible, and are preferably set within a range of about 1 to 5 mm. In this case, one end of the guide member 14 can also be implemented as a shape (not shown) that is inserted into the arc space portion of the upper and lower pressure rollers 10. Thus, by arranging both members close to each other, the tape surface can be accurately crimped and sealed.

  Further, the apparatus of this embodiment is configured such that the abutting plate 12c of the container C is positioned at the upper end of the frame 5a on the back side of the conveyor frames 5a and 5b on the start side of the tape guide member 14 in the container moving direction. The container guide plates 12a and 12b are fixed on the surface of the conveyor 5 with a predetermined interval therebetween, and the interval between the guide plates 12a and 12b is placed on the conveyor as a container guide groove 11. A container transfer guide body 12 is formed so that the placed container C can be transferred toward the tape guide member 14 in a stable posture.

  Further, the sealing side frame B of the embodiment was provided with a cutting blade 81 for cutting the adhesive tape attached to the rear end side in the moving direction of the sealed container with the tape on the component arrangement plate 20. A cutter mechanism 8 is arranged. The cutter mechanism 8 has a cutting blade 81 fixed to one end of an electromagnetic rod 83 supported by an electromagnetic cylinder 82, and is always away from the portion where the tape is cut, and a photoelectric tube for detecting the presence or absence of a container. An intelligent mechanism 84 such as a limit switch, and in the embodiment, the photoelectric tube 84 is installed on the upper surface of the mounting base 85 of the lower pressure roller 10. The rod 83 moves in the tape cutting direction, that is, the conveyor 5 side, and the cutting blade 81 moves to the tape position along with this movement to cut the tape. Needless to say, the cutting blade 81 instantaneously shifts to the tape cutting zone by the operation of the electromagnetic cylinder 82, but at the next moment, due to the non-operation of the electromagnetic cylinder 82, the cutting blade 81 moves to a retreating place away from the tape cutting point. As a structure to return.

  Further, the pair of upper and lower pressure-bonding rollers 10 and 10 are arranged at the top of the mounting base 85 of the lower pressure-bonding roller 10 as shown in FIGS. In addition, a swing mounting base 86 of the upper press roller 10 is disposed so as to swing through the support pin 87, and an operation knob 88 provided at one end of the swing mounting base 86 is pushed down to lower the lower press roller 10. On the other hand, the upper pressure roller 10 is moved upward to form an appropriate space between the rollers 10 and 10. A spring is interposed between the upper and lower pressure roller mounting bases 85 and 86 so that the lower pressure roller 10 is always in pressure contact with the upper pressure roller 10 at an appropriate pressure (not shown).

  As shown in FIG. 3, the sealing side frame B shown in the embodiment having such a structure has the component placement plate 20 supported by support columns 21 s erected from the substrate 21, and the whole of them. Is formed as an integral structure. In addition, the codes | symbols 18 and 18 described in the both ends of the component arrangement | positioning board 20 shown in FIG. 2 are the positioning frames of the conveyor side frame A and the sealing side frame B. As shown in FIG. Reference numeral 71 denotes a lifting frame formed continuously on the left and right ends of the conveyor side frame A.

  On the other hand, the conveyor side frame A shown in the embodiment has a holder 52 for the right rotation shaft 51 transmitted through the conveyor 5 to the rotation of the motor M connected to the left end of the conveyor 5 as shown in FIG. 1, and a pulley 53 is coupled to the projecting shaft portion, and the passive pulley 55 coupled to the rear-side extension shaft 54 of the lower roller in the pressure roller 10 is connected to the conductive pulley shown in FIGS. Power is transmitted through the belt 56. In this way, the diameter ratio between the pulley 53 and the passive pulley 55 is set so that the tape feeding speed of the lower pressure roller 10 and the container feeding speed of the conveyor 5 are synchronized. As indicated by a chain line in FIG. 1, the transmission belt 56 is always given an appropriate tension by a tension pulley 58 that is tensioned by a spring 58s. With this tension, the structure depends on the contraction of the belt as the conveyor-side frame A moves up and down.

  In the sealing device configured as described above, as shown in FIG. 7, the packaging container C containing food such as chicken eggs is placed on the upper surface on the moving start end side of the conveyor 5 in a closed posture, and the polymerization is performed. The peripheral roller 4 is moved to the right while being pressed against the container guide groove 11 formed between the upper and lower guide plates 12a and 12b, and is applied to the guide member 14 together with the adhesive tape 6 formed in a V shape and the pressure roller 10; 10, and the adhesive peripheral edge 4 of the container C together with the pressure-sensitive adhesive tape 6 is pressure-bonded by pressure-bonding rollers 10 and 10, and is adhesively sealed with a double-folded tape. At this time, by setting the tape feeding speed of the pressure roller 10 and the container feeding speed of the conveyor 5 to be synchronized, there is a deviation in feeding between the packaging container C and the adhesive tape 6 while synchronizing them. It is designed to be surely sealed in a state that does not occur. After the packaging container C is sealed with the adhesive tape 6, when the container is separated from between the pressure rollers 10 and 10, the photoelectric tube 84 detects that the cylinder 82 of the cutter mechanism 8 is energized and the rod 83 is moved to the conveyor 5 side. With this movement, the cutting blade 81 cuts the adhesive tape connected to the terminal side of the packaged container C.

  Further, prior to the container sealing operation, if there is a height difference between the height of the sealed portion 4 of the container C and the height between the pressure rollers 10, 10, it protrudes from the front surface of the conveyor side frame A. It is preferable to perform the sealing operation in an optimum state by rotating the up / down operation handle 29 in an appropriate direction to adjust the height of the work position.

It is. The structure of the elevating / lowering mechanism D itself shown in this embodiment is such that the two links 24 described in detail in the first embodiment are crossed in an X shape, and the intersection axis 23 of the cross links 24 is moved laterally. Thus, the inclination angle of the X-shaped link 24 is changed, and the interval between the upper and lower frame bodies connected to the upper and lower ends of the link 24 is changed widely by the undulation of the link 24.

  That is, the sealing side frame B shown in the second embodiment is formed by separately forming the upper frame as the component arrangement plate 20 and the substrate 21 as shown in FIG. This is a structure connected by a link 24. The difference from the first embodiment is that the operation shaft 28 connected to the vertical operation handle 29 is lengthened and the operation handle 29 is arranged on the front surface of the bearing plate 33 fixed to the front surface of the front frame 5b in the conveyor side frame A. This is the point of having a certain structure. In this way, the operation handle 29 is rotated to move the upper frame as the component placement plate 20 up and down so that the height between the pressure rollers 10 can be adjusted with respect to the height of the conveyor 5.

  On the other hand, the operation shaft 28 shown in the embodiment includes a bearing plate 60 fixed to the front surface of the front frame 5b in the conveyor side frame A, and is provided with a long hole 61 along the vertical direction. 15 to 17, the left side wall is formed as a sawtooth triangular triangular uneven wall 62, and the opposite wall, the right side wall in the figure, is formed as a cushion wall 63 having rubber elasticity. As a thing. Further, the operation shaft 28 connected to the operation handle 29A may be the entire circumferential surface. However, in the illustrated example, the portion facing the triangular concavo-convex wall 62 is engaged with the concavo-convex portion of the triangular concavo-convex wall 62 in the illustrated one. An uneven surface 64 is formed.

  Thus, the operation handle 29A shown in the fourth embodiment is simply operated in the vertical direction to move the operation shaft 28 up and down along the elongated hole 61. At this time, the operation shaft 28 moves up and down while resisting the elasticity of the cushion wall 63 while contacting the triangular concavo-convex wall 62 facing the concavo-convex surface 64. When the up / down operation of the operation handle 29A is finished, the triangular concavo-convex wall 62 and the concavo-convex surface 64 are engaged to maintain the position.

  As the operation handle 29A is operated in the up-and-down direction, the operation shaft 28 has its tip portion moved up and down with the operation shaft tip receiving hole 56 of the jig 55 as a fulcrum, and a bearing hole 58 through which the horizontal bar 25 is inserted. The horizontal bar 25 is moved in the vertical direction via. The height of the component arrangement plate 20 is adjusted up and down via the horizontal rod receiver 50 fixed to the lower surface of the component arrangement plate 20 by the vertical movement of the horizontal plate 25.

  In each of the above embodiments, the structure of the conveyor 5 is shown as a structure that is arranged over the entire length in the longitudinal direction of the conveyor side frame A, that is, in the horizontal direction in the drawing. For example, in the figure, the conveyor 5 as an endless belt is formed only in the right half, and the left half is used as a container mounting table that forms the upper surface of the conveyor frame. This may be carried out assuming that the container mounting surface is formed.

  Although typical embodiments of the present invention have been described above, the present invention is not necessarily limited to the above-described embodiments. For example, in the cutter mechanism for cutting the adhesive tape connected to the rear of the sealed container or the conveyor lifting mechanism, any mechanism can be used as long as it can achieve its purpose. Others The present invention achieves its object and can be implemented with appropriate modifications and changes without departing from the scope of the claims.

  The present invention is placed in a merchandise processing room such as a supermarket or in a store, and a container made of a synthetic resin sheet material containing processed sugar beet and other foods is sealed and displayed as it is on the merchandise counter. Since the container can be sealed in front of the customer's eyes, or in some cases, the product purchaser himself can operate and seal the container, it is expected to be used greatly in the market.
