Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging method and apparatus for packaging a triangle-shaped soft packaged object such as a sandwich with a continuous strip film wound on a roll.

[0002]

2. Description of the Related Art Conventionally, triangular sandwiches in which contents such as meat and vegetables are sandwiched between stacked breads are sold in a state of being wrapped with a transparent film. An example of a packaging machine for packaging a triangular soft packaged object such as a sandwich is described in, for example,
As disclosed in, for example, No. 10202 and Japanese Utility Model Laid-Open No. 60-171805, a sandwich bag that is pre-manufactured by hand is used in a packaging machine by using a bag that is already provided with an opening into which the sandwich can be inserted. It has been proposed that the opening of the bag is automatically folded and sealed with tape or the like by supplying.

[0003]

In the above-mentioned conventional packaging machine, since all the bags are packaged by using the already manufactured bags, the bags having the sizes according to the specifications of sandwiches having different outer dimensions and thicknesses are used. Therefore, there is a drawback that the inventory management becomes complicated and the packaging cost increases. Further, in order to insert the sandwich through the opening of the bag, a bag manufactured to have an internal dimension with a margin with respect to the outer dimension of the sandwich is used. Therefore, when the sandwich is packaged in the bag, there is a drawback that a gap is generated between the sandwich and the bag (dumbness occurs), and the commercial value is lowered. Moreover, it is pointed out that the cost of the packaging material is increased and the cost is increased.

Further, inserting the sandwich into a bag (packing)
Since the work depends on human labor, there is a problem that the work is troublesome and the labor cost cannot be reduced. Moreover, when the sandwich is inserted into the bag, the contents of the sandwich rub against the inner surface of the bag and stain the bag, resulting in poor appearance and reduced commercial value.

[0005]

[Regarding Article Discharge Mechanism] At the downstream end of the transfer conveyor 46, discharge members 109, 109 (moving forward and backward in the transport direction via a link mechanism 108 as shown in FIG. 16 to the outside sandwiching both side plates 47, 47). (Only one shown) is installed,
The discharge members 109, 109 are positioned so as to move to a position where they can contact the bottom surface of the sandwich 11 held by the holding member 53. That is, when the gripping member 53 of the transfer conveyor 46 reaches the discharging position of the sandwich 11 and is intermittently stopped at the appropriate timing, when the movable plate 55 is opened by the opening mechanism 60 described above, the link mechanism 108 causes the discharging member 109,
By moving 109 toward the downstream side in the transport direction, the sandwich 11 of the gripping member 53 is pushed out and released to the outside of the system via the chute 122.

[0044]

Operation of the Embodiment Next, the operation of the packaging apparatus according to the embodiment will be described. In addition, the strip-shaped film F is spread on the downstream side of the supply conveyor 14 without a seal portion, and the sandwich 1 in the transfer conveyor 46 is provided.
It is assumed that the holding member 53 stands by at the receiving position 1 with the movable plate 55 opened.

In this state, the concave portion 2 of the positioning base 22
When the sandwich 11 faces the 2a, the sandwich 11 is placed at the center of conveyance of the conveyor belt 18 with the top of the sandwich 11 oriented upstream. Supply conveyor 1
When the detecting means 120 detects that the sandwich 11 has been conveyed to the predetermined position by the intermittent movement of the cylinder 4, the cylinders 24, 24 are urged, and the both feeding plates 2 are pushed.
7, 7 and 27 move closer to each other, and as shown in FIG. 5, the pushing portions 27a and 27a are brought into contact with both inclined surfaces of the sandwich 11 which is stopped at a predetermined position due to the intermittent stop of the supply conveyor 14. Then, in synchronization with the intermittent movement of the supply conveyor 14, both cylinders 24, 24 are guided by the guide rods 23, 2 at the same speed.
By moving to the downstream side along 3, the sandwich 11 is supplied from the bottom side toward the expanded portion of the strip film F.

The stretched strip-shaped film F includes:
The pull-out portions 27b, 27b of the pushing plates 27, 27 first come into contact with each other, and the strip-shaped film F is pushed to the downstream side as the plates 27, 27 move forward, so that the upper and lower tension rollers 34, 37 move upward. And the film F is pulled out. As a result, the strip-shaped film F is wound around the bottom surface and the side surface side (lower upper surface on the supply conveyor) of the sandwich 11. Then, as shown in FIGS. 6 and 8, at the timing when the sandwich 11 arrives between the vertical portion 54c and the movable plate 55 of the holding member 53 standing by at the receiving position, and the intermittent stop is performed, the opening mechanism 60 is released. It operates to move the operating lever 62 to the movable plate 55.
It is separated from the projecting piece 55a. As a result, the movable plate 55 moves to the vertical portion 54c side under the elastic force of the compression spring 58, and elastically grips the sandwich 11 from the thickness direction.

Next, the upper and lower fusing sealers 43, 44
Move closer to each other, and the band-shaped film F wound around the sandwich 11 is cut by the abutting of the fusing sealers 43 and 44 at approximately the center in the thickness direction on the inclined surface side of the sandwich 11. As a result, as shown in FIG. 17 (a), the sandwich 11 is wrapped around the film 13 in which the fusing seal line (seal portion) is formed substantially at the center in the thickness direction on the inclined surface side. The pushing plates 27, 27 are the film F formed by the fusing sealers 43, 44.
The sandwich 11 is held in a state of being supported from both sides until the seal cutting is completed, and the cylinders 24, 24 are held at appropriate timings when the sealers 43, 44 are separated from each other.
Is biased in the opposite direction, and the pushing plates 27, 27 are separated from each other. Then, both cylinders 24, 24 are connected to the guide rod 23,
It retreats (moves upstream) along 23 and waits for the arrival of the next sandwich 11. The pushing plate 27,
The upper and lower end portions of 27 in the height direction face substantially the same positions as the upper and lower end portions of the sandwich 11, and the supporting portion 2
Since the films 27c and 27c face the vicinity of the rear end (near the top) of the sandwich 11 in the feeding direction, the film F is sealed by the sealer 4
When wrapped around the sandwich 11 by 3,44,
The shape of the sandwich 11 is not destroyed by the film F.

Here, when the band-shaped film F is seal-cut by the sealers 43 and 44, the air cylinder 4
1, the lower tension roller 37 is forcibly lowered to a lower fixed position, and the winding roller 36 is rotationally driven by the drive motor 35 to wind the strip film F. When the pulse transmission means 40 arranged on the guide roller 38 counts the preset number of pulses, the motor 35 stops and the winding of the strip film F is stopped. As a result, the seal portion attached to the band-shaped film F by the sealers 43 and 44 is moved to the lower position not used for the next packaging. That is, the device 1 of the embodiment
In No. 0, the sandwich 11 is wound around the tubular film 13 in which only one sealing portion is formed in the center of the sandwich 11 in the thickness direction on the inclined surface side. Further, the origin sensor 42 indicates that the feeding roller 32 is rotationally driven by the drive motor 31 and the strip-shaped film F is pulled out from the film roll 30 so that the tension roller 34 located above is lowered from the raised position to the origin position. When detected, the motor 31 stops and the film drawing stops.
As a result, the strip-shaped film F for the next packaging is stretched and held between the upper and lower tension rollers 34 and 37.

The gripping member 53 which grips the sandwich 11 in which the film 13 is wound by the above-mentioned process is intermittently driven by the transfer conveyor 46 so that the first bent body 72,
At the timing of reaching the lower side of 72 and intermittently stopping, as shown in FIG. 11, the guide bar 67 is lowered and the film 13 facing the inclined surfaces of the sandwich 11 faces the first bent body. It is bent by 72 along the corresponding inclined surface. In addition, the first bent body 72,
Film 1 bent by 72 along each inclined surface
3 and the film 13 extending outward from the bottom surface of the sandwich 11, the linear seal line 1 is formed by the pressing plate 73 and the sealer 74 in the vicinity of the base thereof.
By forming 30 and 130, a temporary seal is applied (see FIG. 17B).

By the intermittent drive of the transfer conveyor 46,
After the gripping member 53 that grips the sandwich 11 reaches the downstream side of the position where the second bent body 76 is disposed and stops, the support body 75 descends, and the second bent body 76 moves upstream of the sandwich 11. Face to the side. Then, by moving the second bent body 76 to the downstream side, the upstream side extending portions 13a, 13a extending from the inclined surface of the sandwich 11 are bent along the inclined surface (Fig. 17 ( See c)). The second bent body 76 is lifted at an appropriate timing when the gripping member 53 that grips the sandwich 11 is moved toward the third bent body 80 on the downstream side by the next intermittent drive, Retreat and return to the initial standby position.

When the gripping member 53 passes through the position where the third bent body 80 is disposed, the laterally extending portions 13a, 13a on the downstream side that extend outward from the inclined surface of the sandwich 11 are provided.
Is bent along the inclined surface by the third bending body 80 and overlaps with the upstream side extending portions 13a, 13a.
(See FIG. 17 (d)). Then, the downward extending portions 13b, 13b extending outward from the bottom surface of the sandwich 11 are conveyed to the downstream side while facing between the folding guides 81, 82. The downward extension 13b is conveyed to the downstream side in a state in which it is inclined slightly above the level of the bottom surface of the sandwich 11.

In each tape applying mechanism 102 arranged on the downstream side of the arrangement position of the third folded body 80, the tape 83 is horizontally placed on the upper surface of the table 88, and 88 faces the tape application position near the transfer conveyor 46. Therefore, when the gripping member 53 gripping the sandwich 11 arrives at the position where the pasting mechanism 102 is disposed, the downward extending portion 13b faces above the tape 83 placed on the table 83. Then, at the timing when the gripping member 53 is intermittently stopped,
The second cylinder 91 is urged and the attaching member 93 descends to press the downward extending portion 13b against the tape 83, so that the tape 83 is attached to the lower surface of the downward extending portion 13b. Further, the third cylinder 92 is urged to press the pressing members 95 located on the left and right sides of the perforation forming knife 94,
95 is lowered, and the portion of the downward extension 13b to which the tape 83 is not attached is clamped between the base 96 and the receiving base 96.

Next, the second cylinder 91 is reversely biased to retract the pasting member 93 upward, and then the first cylinder 84 is biased to move the table 83 and the tape roll 86 toward the standby position. As a result, the tape 83 is pulled out from the tape roll 86. Tape roll 8
When 6 moves to the standby position, the fourth cylinder 98 is urged to lower the perforation forming knife 94 and the tape cutting knife 100. As a result, perforations 101 for opening are provided in the thickness direction of the sandwich 11 in the downward extending portion 13b facing between the pressing members 95, 95, and the tape 83 is attached to the inclined surface side. Is cut at the position where the mark remains (see FIG. 17 (e)). Note that FIG.
In FIG. 11, only the tape 83 is attached to the lower extending portion 13b on the right side, and the perforation 101 is not provided.

The downward extending portions 13b, 13b to which the tapes 83, 83 are attached are inclined portions 82c, 82 of the folding guides 82, 82 with the intermittent movement of the gripping member 53.
It is gradually bent upward by c, and finally brought into a substantially vertical state. This sandwich 11 is a folding guide 8
At the timing of reaching the position of the opening 82d provided in No. 2 and intermittently stopping, each of the cylinders 104 is urged and the adhesive member 105 opens the opening 8 as shown by the two-dot chain line in FIG.
2d extending inward, and the downward extending portion 13 in a vertical state
B is bent along the inclined surface of the sandwich 11, and the adhesive margin of the tape 83 is adhered to the film 13 already bent along the inclined surface. This allows
A package P in which the sandwich 11 is tightly packaged with the film 13 is obtained (see FIG. 17 (f)).

At an appropriate timing when the gripping member 53 gripping the sandwich 11 arrives at the discharge position and stops due to intermittent movement, the opening mechanism 60 operates to open the movable plate 55 of the gripping member 53. Further, the link mechanism 108 is operated, and the discharge member 1 connected to the link mechanism 108 is operated.
By moving 09 and 109 toward the downstream side, the sandwich 11 is extruded from the grip member 53 and discharged to the outside of the system via the chute 122.

As described above, the sandwich 1 is formed by the strip-shaped film F continuously drawn from the film roll 30.
Since 1 can be packaged, the manufacturing efficiency can be significantly improved. Further, a change in the thickness dimension due to a change in the number of stacked sandwiches 11 or the like can be easily dealt with by changing the supply amount of the film F without changing the width dimension of the strip film F. Therefore, it is not necessary to prepare films of various sizes according to the thickness size of the sandwich 11, and the packaging material cost can be reduced. Moreover, since the perforation 101 is provided to the one downward extension portion 13b, it is possible to easily open the perforation 101 as a guide.

[0057]

As described above, according to the method and apparatus for packaging a flexible packaged object such as a sandwich according to the present invention, the packaged object is wrapped by the continuous strip-shaped film drawn from the supply source. Since it is not necessary to manufacture bag-making bags of various sizes, the packaging cost can be reduced. In addition, even if there is a change in the external dimensions of the packaged item, the film can be tightly adhered according to the dimensions of the packaged item, thereby improving the commercial value and efficiently using the film. As a result, the packaging material cost can be kept low.

Further, a series of operations from the winding of the film on the object to be packaged to the sealing of the extended portions of the film can be automated, and labor can be saved. Furthermore, since it is not a method of inserting the object to be packaged in the bag, in the case of an object to be packaged such as a sandwich, the contents of the sandwich do not rub the inner surface of the film and stain the film, which reduces the commercial value. There is also an advantage to improve.
