 The present invention relates to a packaging device for agricultural products that wraps an object to be packaged (for example, vegetables such as lettuce and cabbage, or fruits such as melon and apple) with a packaging sheet.

[0002]

[Prior art]

 An example of the packaging device as described above is disclosed in Japanese Patent Application Laid-Open No. 3-133710. In other words, a packaging table having an opening through which the object to be packaged falls is provided, the packaging sheet cut to a predetermined length is placed on the packaging table, and the object to be packaged is dropped into the opening from above. As a result, the packaging sheet is squeezed at the outer edge of the opening, the packaged item is wrapped in the packaging sheet, and is supported by the lower support table, after which the excess portion of the squeezed packaging sheet is cut and cut. This is a configuration in which the packaging sheet is fastened.

In the packaging device as described above, a pulling-out mechanism for pulling out a packaging sheet of a predetermined length to a predetermined position on the opening of the packaging table and a packaging sheet for the next packaging after the completion of one packaging. It has been proposed to have a cutter that cuts to length. In this structure, for example, as shown in FIG. 10A, the packaging sheet 1 is wound in a roll shape, and the packaging sheet 1 is placed on a pair of freely rotating support rollers 5 (corresponding to support members). Then, as shown in FIG. 10B, they are arranged below the cutter 12 for cutting the packaging sheet 1 at predetermined intervals along the roll axis direction of the packaging sheet 1, and have the same height. A plurality of first receiving portions 10a and a plurality of second receiving portions 10a that are arranged to face each of the first receiving portions 10a at predetermined intervals and have the same height as that of the first receiving portions 10a. The portion 10b is arranged.

As a result, as shown in FIG. 10A, the drawer mechanism 16 moves from the right side to the left side of the drawing, and the plurality of receiving portions 20 and the operation arm 19 of the pulling mechanism 16 are moved to the respective first receiving portions.

The first and second sandwiching parts include a plurality of second sandwiching parts that can be inserted between the first receiving parts. It is inserted between the respective second receiving portions and between the respective first receiving portions, and one of the first and second holding portions is moved to the other side, so that the packaging sheet of the packaging sheet is moved by the first and second holding portions. Clamping position where the end is clamped, and while rotating the roll body of the packaging sheet, the clamped packaging sheet is pulled out on the packaging table for a predetermined length. After being pulled out to a predetermined length and stopped at the pulling-out position, it is provided with a horizontally long cutter that cuts the packaging sheet from above the packaging sheet until it falls between the first receiving portion and the second receiving portion. There is.

[0008]

[Action]

 For example, as shown in FIG. 4, after the packaging sheet 1 is pulled out to a predetermined length by the pull-out mechanism 16, the cutter 12 is lowered to cut the packaging sheet 1, and the packaging sheet 1 is cut by the cutter 12. Even if it is dragged and turned downward, the end portion 1b of the packaging sheet 1 tends to return upward due to its own elasticity or the rising of the cutter 12 after the cutter 12 is lifted. In this case, if the second receiving portions 10b are set lower than the first receiving portions 10a as in the present invention (see FIG. 1), the end portion 1b of the packaging sheet 1 will return upward. In this case, since each second receiving portion 10b is located below the movement locus of the end portion 1b, the end portion 1b of the packaging sheet 1 is obstructed by each second receiving portion 10b. Instead, it returns upward and the end 1b of the packaging sheet 1 is positioned diagonally above each second receiving portion 10b or is placed on the upper surface of each second receiving portion 10b.

After the packaging sheet 1 is cut as described above, for example, as shown in FIG. 1, the pulling-out mechanism 16 advances toward the packaging sheet 1 side again, and the first and second nipping of the pulling-out mechanism 16 is performed. It is assumed that the parts 20 and 19 enter between the first receiving parts 10a and between the second receiving parts 10b (see FIG. 6). In this case, the first holding part 20 is located higher than the first receiving part 10a, and the second holding part 19 is located lower than the second receiving part 10b. Even if the portion 1b is on the upper surface of the second receiving portion 10b, the end portion 1b of the packaging sheet 1 surely enters the space between the first and second sandwiching portions 20 and 19 of the pullout mechanism 16, and the first portion Also, the end portion 1b of the packaging sheet 1 is sandwiched by the second sandwiching portions 20 and 19. Therefore, in this state (the end of the packaging sheet does not enter downwardly between the first and second receiving portions, and the end of the packaging sheet is sandwiched between the first and second sandwiching portions of the drawer mechanism. In this state, the packaging sheet may be pulled out by the pulling mechanism.

[0010]

[Effect of device]

 As described above, when the cutter cuts the wrapping sheet pulled out to the predetermined length, the end of the wrapping sheet does not enter between the first and second receiving portions, and the end of the wrapping sheet is pulled by the pulling mechanism. Since it is possible to reliably hold the sheet, it is possible to prevent the package sheet from being pulled out or broken by the pulling mechanism.

As shown in FIGS. 1 and 6, a plurality of first receiving portions 10a are arranged below the end portion 1b of the drawn-out packaging sheet 1 at predetermined intervals along the roll axis direction of the packaging sheet 1. The first receiving portions 10a are set to the same height. The second receiving portions 10b are arranged to face each of the first receiving portions 10a on the opposite side of the packaging sheet 1 wound in a roll shape with a predetermined space therebetween, and each of the second receiving portions 10b is connected to the first receiving portion 10a. It is set to the same height, which is lower than a by a difference a1.

As shown in FIGS. 1 and 6, a pair of support plates 17 are slidably supported along guide rails 2 b provided on both the left and right sides of the packaging table 2, and the left and right support plates are supported. One support shaft 18 is laid across 17 and five operation arms 19 (corresponding to a second holding portion) are independently fitted to the support shaft 18 so as to be independently swingable. A rubber plate 19a is fixed to the top surface of the tip. Then, five receiving portions 20 (corresponding to the first holding portions) having substantially the same width as the operating arm 19 are fixedly supported on the upper side of the operating arm 19, and the rubber plate 20a is fixed to the lower surface of the receiving portion 20. Each operation arm 19 is provided with five springs 21 for urging the operation arm 19 toward the receiving portion 20 on the swing side, and the drawer mechanism 16 is configured as described above. In this case, as shown in FIG. 1, when the operation arm 19 is being pulled down, the receiving portion 20 of the drawer mechanism 16 is located at a position higher than the first receiving portion 10a by the difference a2. The tip of the operating arm 19 is located at a position lower than the second receiving portion 10b by a difference a3.

The support shaft 18 is rotatably supported with respect to the support plate 17, an arm 18a is fixed to the left and right of the support shaft 18, and one rod 18b is provided over the left and right arms 18a (see FIG. 6). ) Is erected and fixed. A link 23 is installed between the fan-shaped gear 22 swingably supported on one support plate 17 and the one arm 18a, and a motor 24 for driving the fan-shaped gear 22 is provided. The state shown in FIG. 1 is a state in which the motor 24 is driven to push up the rod 18b (see FIG. 6) to pull down each operation arm 19 from the receiving portion 20, and the motor 24 is driven in reverse as described later. Then, when the rod 18b is pulled down, the operating arms 19 are lifted to the receiving portion 20 side by the biasing force of the springs 21 to clamp the packaging sheet 1.

As shown in FIGS. 1 and 6, a support frame 13 is disposed above the first and second receiving portions 10 a and 10 b, and the support frame 13 has a width wider than the lateral width of the packaging sheet 1. A flat plate-shaped cutter 12 having is fixed. The plate-shaped pressing member 15 having a width of about ½ of that of the packaging sheet 1 is provided on the front side and the left side of the cutter 12 and on the rear side of the left and right four in total. A rubber plate 15a is attached to the lower surface of each of the holding members 15, and each holding member 15 is provided so as to be vertically movable on the support frame 13 and urged downward by a spring 15b. As shown in FIG. 1, the rubber plate 15a of the pressing member 15 is set to project below the lower end of the cutter 12.

As shown in FIG. 6, the boss portions 13a fixed to the left and right of the support frame 13 are externally fitted to the left and right guide rails 9, and the entire support frame 13 is slidably supported in the vertical direction. A crank mechanism (not shown) and a motor (not shown) arranged on the lower side of the base 2 and the left and right boss portions 13a of the support frame 13 are connected via a link link 29. With this, when the crank mechanism is rotated once by the motor, the support frame 13 and the cutter 12 are lowered, the cutter 12 is inserted between the first and second receiving portions 10a and 10b, and the packaging sheet 1 is cut, The support frame 13 and the cutter 12 are again moved up.

(4) Next, the flow of operation of the pull-out mechanism 16 and the cutter 12 when the packaging sheet 1 is pulled out onto the packaging table 2 for the next packaging after the end of one packaging will be described. The state shown in FIG. 1 and FIG. 2 (a) is a state in which one packaging is completed, and in order to pull out the packaging sheet 1 for the next packaging onto the packaging table 2, the pull-out mechanism 16 is moved to the cutter 12 side. It is in a state of moving. In this state, the pair of braking members 27 are pressed by the support roller 5, and the support roller 5 is being braked. Then, as shown in FIG. 2B, when the operation arms 19 and the receiving portions 20 of the drawer mechanism 16 enter between the first and second receiving portions 10a and 10b and the drawer mechanism 16 stops (holding (Equivalent to the position), the end portion 1b of the packaging sheet 1 is inserted between each operation arm 19 of the drawing mechanism 16 and the receiving portion 20.

In this case, as shown in FIG. 1, when the operation arm 19 is being pulled down, the receiving portion 20 is located at a position higher than the first receiving portion 10a by the difference a2, and the second receiving portion 10a is positioned higher than the first receiving portion 10a. Since the tip of the operation arm 19 is located at a position a3 lower than 10b, the end portion 1b of the packaging sheet 1 is surely inserted between each operation arm 19 and the receiving portion 20 of the drawer mechanism 16. . Next, the motor 24 of the pull-out mechanism 16 is actuated to pull down the rod 18b, and the urging force of each spring 21 raises each operation arm 19 to the receiving portion 20 side, so that each operation arm 19 and the receiving portion The end 1b of the packaging sheet 1 is sandwiched by 20 and.

Next, as shown in FIGS. 2B to 3, the drawer mechanism 16 starts to move to the right in the drawing with the end portion 1b of the packaging sheet 1 being held, and the packaging table 2 of the packaging sheet 1 is moved. Start pulling up. In this case, as shown in FIG. 3, the operating arm 33 (see the state of FIG. 1) that has been raised is lowered, and the upper ends of both braking members 27 are separated from both support rollers 5 against the spring 30. Operated. As a result, the pair of support rollers 5 can freely rotate, so that the roll body of the packaging sheet 1 rotates together with the support roller 5 as the packaging sheet 1 is pulled out, and the packaging sheet 1 is pulled. The delivery is done smoothly.

As shown in FIGS. 1 and 6, in the packaging table 2, a pair of right and left rubber plates 33 made of urethane rubber are provided between the second receiving portion 10b and the opening 2a. As a result, as shown in FIG. 3, the left and right rubber plates 33 are constantly in contact with the lower surface of the packaging sheet 1 while the packaging sheet 1 is being pulled out by the pulling-out mechanism 16, so that the packaging sheet 1 and the packaging base 1 are in contact with each other. A space is constantly formed between the packaging sheet 1 and the sheet 2 and the state in which the entire packaging sheet 1 is in close contact with the packaging table 2 is prevented. Since the rubber plate 33 is provided on the packaging table 2 so as to be located between the operation arms 19 of the drawer mechanism 16, when the drawer mechanism 16 moves to the cutter 12 side as shown in FIG. The rubber plates 33 do not pass between the operation arms 19 of the pull-out mechanism 16 and come into contact with each other, and even if they contact each other, the rubber plates 33 elastically deform and escape from the operation arms 19.

As shown in FIG. 4, the packaging sheet 1 is transparent, but the marks 1c are printed along the longitudinal direction of the packaging sheet 1 at predetermined intervals corresponding to the type of the article A to be packaged and the like. As shown in FIG. 6, a frame 25 fixed to the packaging table 2 is provided with a reflection type optical sensor 26 including a light emitting device and a light receiving device. With the above structure, the packaging sheet 1 is pulled out, and as shown in FIG. 4, the mark 1c of the packaging sheet 1 reaches the position of the optical sensor 26, and the detection light from the light emitter of the optical sensor 26 is detected by the mark 1c. When the light is reflected by and is detected by the light receiver of the optical sensor 26, the drawer mechanism 16 temporarily stops at that position (corresponding to the drawer position).

In this case, as shown in FIGS. 3 to 4, the operation arm 33 is operated to be raised, and the lower portions of both the braking members 27 are attracted to each other by the action of the spring 30, and the upper ends of both the braking members 27 are supported by both. The rollers 5 are pressed by the outer surface of the rollers 5, and the both supporting rollers 5 are braked. As a result, the roll body of the packaging sheet 1 and the supporting roller 5 are immediately stopped at the same time when the pulling mechanism 16 is stopped. Therefore, between the roll body of the packaging sheet 1 and the pull-out mechanism 16, the packaging sheet 1 does not wavy or wrinkle.

Next, as shown in FIG. 4, the support frame 13 provided with the cutter 12 and the pressing member 15 is moved down. In this case, since the rubber plate 15a of the pressing member 15 projects below the lower end of the cutter 12 as shown in FIG. 1, when the support frame 13 is lowered, first, the four pressing members before and after the cutter 12 are pressed. The member 15 presses and holds the packaging sheet 1 against the first and second receiving portions 10a and 10b. When the supporting frame 13 is further lowered from this state, the cutter 12 enters between the first receiving portions 10a and the second receiving portions 10b to cut the packaging sheet 1 at a stretch as shown in FIG. To do.

When the packaging sheet 1 is cut by the cutter 12 as described above, even if the packaging sheet 1 is held by the pressing member 15, the packaging sheet 1 is dragged while being cut by the cutter 12 and is dragged downward. In some cases, the end portion 1b (see FIG. 1) on the roll body side of the packaging sheet 1 may be drawn between the first receiving portion 10a and the second receiving portion 10b. In this case, as shown in FIG. 1, the second receiving portions 10b are set lower than the first receiving portions 10a by the difference a1, so that the end 1b on the roll body side of the packaging sheet 1 is cut by the cutter. Even if the user is dragged down by 12 and faces downward, the end 1b is pulled onto the upper surface of the second receiving portion 10b, and the end 1b is drawn between the first receiving portion 10a and the second receiving portion 10b. There is no such thing. As shown in FIG. 1, when the operation arm 19 is being pulled down, the receiving portion 20a is located at a position a2 higher than the first receiving portion 10a and is higher than the second receiving portion 10b. Since the tip of the operation arm 19 is located at a lower position by a3, even if the end portion 1b of the packaging sheet 1 on the roll body side is on the upper surface of the second receiving portion 10b, the end portion 1b of the packaging sheet 1 is not affected. Is reliably inserted between the operation arms 19 of the pull-out mechanism 16 and the receiving portion 20 and clamped.

When the cutting of the packaging sheet 1 is completed as described above, the support frame 13 of the cutter 12 is lifted to its original position as shown in FIGS. 4 to 5, and the drawer mechanism 16 is moved to the right side of the drawing. It is moved to one side and stopped so that the center of the cut packaging sheet 1 comes to the position of the opening 2a of the packaging table 2 (see FIG. 6). After that, each operation arm 19 of the drawer mechanism 16 is pulled down from the receiving portion 20 to separate the end portion 1b of the packaging sheet 1, and one packaging sheet 1 cut to a predetermined length is placed on the packaging table 2 at a predetermined position. Placed on. In this case, as shown in FIGS. 5 and 6, since the pair of rubber plates 33 of the packaging table 2 are in contact with the lower surface of the cut packaging sheet 1, air is trapped between the packaging sheet 1 and the packaging table 2. Even if the packaging sheet 1 is lifted up, the packaging sheet 1 does not move from that position due to the contact and frictional action between the rubber plate 33 and the packaging sheet 1.

[Other Example] Although the packaging sheet 1 is fastened with the adhesive tape 4 in the above-described examples, the packaging sheet 1 is heated to weld the packaging sheet 1 after cutting the upper portion 1a, and the packaging sheet 1 is packaged. The present invention may be applied to a packaging device that seals the sheet 1. Further, instead of the disc cutter 28 shown in FIG. 8 (a), a packaging device that heats and fuses the upper portion 1a of the packaging sheet 1 sandwiched by the sandwiching members 14 with a heater (not shown). The present invention may be applied to. Then, when the package A is placed on the packaging sheet 1 of the packaging table 2 without equipping the packaging table 2 with the openings 2a as shown in FIG. 6, the outer peripheral portion of the packaging sheet 1 is lifted and the packaging sheet 1 is packaged. The present invention can be applied to a packaging device configured to wrap the accessory A.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
