Abstract

PURPOSE:To prevent a tied part of a film from obstructing the verification of a cut end of an agricultural product, and make it possible to verify the freshness of the agricultural product visually from the cut end by tie-forming a tied part of a film at a different location than the cut end of an agricultural product. CONSTITUTION:By sliding elements 43, 45, the peripheral side parts of a film F which packages an agricultural products A are approximately simultaneously contracted from the front and rear, and right and left directions through the agricultural products A on a receiving element 25. The peripheral side parts of the film F are collected on the top of the agricultural product A and tie-sealed by a heater 77, and the agricultural product A is packaged by the film F under a condition in which the whole body is totally covered. Also, since a cut end B of product A is supported by a tilted supporting edge 31 of an annular supporting part 30 for the receiving element 25 under such a condition in which the cut end B is deviated from the center, the sealing part of the film F which packages the agricultural product A under this condition is formed on the top of the agricultural product A, which is away from the cut end B of the agricultural product A. Therefore, the cut end B of the agricultural product A can be easily verified visually through the film F from the outside.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention relates to an agricultural product packaging device, for example, for packaging head vegetables such as cabbage, Chinese cabbage, lettuce, and broccoli, and fruits such as summer mandarin oranges and zapon in a film. Relates to items that are automatically packaged by

(Prior Art) Conventionally, in this type of agricultural products packaging device, for example, a guide hole for lowering the agricultural products is formed in a plate-shaped support for supporting a film, and the agricultural products are received and taken in the lower part of this guide hole. There is a structure in which a receiving body is provided to be movable up and down, and a film sealing mechanism is provided on one side of the supporting body to wrap and seal the agricultural products on the receiving body with a film.

Then, when a film is expanded and supported on the support with the guide holes closed, and agricultural products are fed into the guide holes through this film, the agricultural products pull out the film on the support with their own weight and this The film is dropped onto a receiver through the film, and the receiver is raised and lowered to a predetermined position, and the film sealing mechanism is activated. It is designed to be sealed.

(Problems to be Solved by the Invention) In the above structure, the agricultural products are dropped onto the receiver while pulling out the film on the support from the guide hole of the support, but at this time, the agricultural products are not exposed to the heat of the film after packaging. Film sealing is used because agricultural products are generally collected on a receiver with the cut end of the root facing upward, that is, upside down, to prevent the binding part caused by the seal from forming on the surface of the product. When the binding part of the film that wraps the agricultural products is formed into a bundle on the top of the agricultural products by the mechanism, the binding part of this film will be located on the cut of the root of the agricultural products, and this binding part will cause the cut 1-1 to be formed. There is a problem in that it becomes difficult for consumers to visually check the freshness of agricultural products through the cut side of the agricultural products. Note that when the freshness of agricultural products, such as head vegetables, decreases, the cut 1-1 quickly discolors, so checking the cut [] is an important point to confirm the freshness.

Therefore, the present invention has been made in view of the above problem, and it is possible to form the binding portion of the film at a position different from the cut end of the agricultural product when wrapping agricultural products with a film and binding the film. To provide a produce packaging device in which the freshness of the produce can be easily visually confirmed through the cut without the binding part of the film getting in the way of checking the cut of the produce. The purpose is to

Next, the operation of the above embodiment will be explained.

Operate the electric motor 14 to drive the sprocket 13. When the screw punch 12 is rotated via the endless chain 17 between the screw punches 16 and 16, the lifting plate 19 suspended from the screw punch 12 via the nut body 18
is lifted up guided by the screw punch 12 and the guide bar, and the receiving body 25 provided on the lifting plate 19 via the protruding plate part 30 and the support column 21 is lifted from the guide hole 8 of the mounting body 7 to the support body. - is struck toward the straight F of the guide hole 5 of No. 4. When the elevating plate 19 is moved to a position facing the first sensor 33, the elevating plate 19 moves the first sensor 3
3 is activated, the operation of the electric motor 14 is stopped by the output signal of this first sensor 33, and the lifting of the elevating plate 19 is stopped, and the receiving body 25 on this elevating plate 19 is guided by the support body 4. It is arranged directly under the hole 5, and makes this receiver 25 ready for receiving the agricultural products A.

Next, the film supply fitl 194 is operated to supply the film F that allows the agricultural products after packaging to be seen from the outside onto the support body 4, and the guide hole 5 of the film F is passed onto the support surface 6 of the support body 4. Deploy and support in a closed state.

Next, from above the film F, for example, cabbage, Chinese cabbage, etc.
When agricultural products A, such as head vegetables such as lettuce and broccoli, and fruits such as summer mandarin oranges and zapon, are supplied with the cut side B facing upward, the agricultural products A are exposed to the film F.
While pulling out the film F from the support surface 6, it is lowered from the guide hole 5 onto the net body 29 of the receiving body 25.

Further, when agricultural products A are lowered and supported on the net body 29 with the film F, the net body 29 is stretched downward within the receiving body 25 by the weight of the agricultural products A, and
While the film F is narrowed along the external shape of the agricultural product A by the net body 29, the agricultural product A is transferred to the receiving body 2.
5 and the lower part of the produce is supported by the support edge 31 of the annular support 30 at its bottom. Therefore, the film F is fixed to the outside of the agricultural product A by the net body 29 in a manner similar to the shape of the agricultural product A, and the agricultural product A is stably inserted into the receiving body 25 via the film F and the net body 29. It is well received.

In this case, the support edge 31 of the annular support part 30 that supported the agricultural products A is formed to be inclined downward toward one side at the upper edge of the opening, so that the agricultural products A are received in the annular support part 30. At the same time, the supporting edge 31 automatically tilts the agricultural product in the inclination direction, and the cut B at the top thereof is deviated to one side from the upper center. Furthermore, since the film F pulled out downward from the support 4 is not in close contact with the support surface 6 of the support 4, it is smoothly pulled out from above the support surface 6 as the agricultural products A descend.

Next, when the electric motor is activated and the screw 12 is rotated in conjunction, the lifting plate 19 is guided by the screw 12 and the guide rod.
Then, the receiver 25 on this elevating plate 19 is lowered, and the agricultural products A are lowered below the guide hole 8 of the support 7, and the film F between the receiver 25 and the agricultural products A is
As the agricultural product A descends, it is supported by the agricultural product A and smoothly pulled out from the support surface 6 and the guide hole 5. When the upper part of the agricultural products is lowered to a predetermined position of the film sealing mechanism 40, a detection means (not shown) is activated, and an output signal from the detection means stops the operation of the electric motor 14, and the lifting plate The downward movement of agricultural product A due to +9 is stopped.

Further, when the operation of the electric motor 14 is stopped, the cylinder equipment rFf 57 is operated, and this piston rod 58 is extended, and the lower slide body 45 is moved by the plurality of guides 46 via the interlocking arm 55 by this piston rod 58. It is slid from the outer side toward the inner guide hole 5 along the lower front and rear guide rods 42 via.

Further, when the lower slide body 45 is moved toward the guide hole 5, the pinion 52 meshed with the rack 51 of the lower slide body 45 is rotated, and the pinion 52 meshed with the rack 51 of the lower slide body 45 is rotated. The upper slide body 43 is interlocked with a plurality of guides 44.
It is moved from the outer side toward the lower part of the inner guide hole 5 along the upper front and rear guide rods 42 via. Then, the left and right upper and lower slide bodies 43 and 45 are moved from the left and right direction directly below the guide hole 5, and the opposing focusing recesses 48 and 49 at the inner ends of the left and right slide bodies 43 and 45 overlap. The left and right portions of the film F on the receiver 25 are sequentially moved from the left and right direction through the produce A to the upper part of the produce A by the narrowing edges 48s and 49g from the enlarged portions of the left and right focusing recesses 48 and 49. Narrowed down.

Further, as described above, the lower slide body 45 is connected to the guide hole 5.
When the slide body I5 is moved toward the lower part of the
As a result, the pair of opening/closing rods 87 are interlocked with the movement of the lower slide body 45 toward the guide hole 5. By the movement of the pair of opening/closing rods 87, the guide rollers 9o of the respective extension rod portions 87b are sequentially engaged and guided from the release portion 81 of the pair of guide bodies 80 to the slanted guide portion 82 to the binding portion 83. At the same time, the pair of opening/closing rods 87 are gradually rotated about the rotation center axis 85 against the coil spring 92, and the respective focusing rods on the upper part of the clamping plate 67 of the pair of opening/closing rods 87 are rotated. The parts 871 are rotated in a direction in which they approach each other from the front and rear directions, and the front and rear focusing rod parts 871 of the front and rear focusing rods cause the front and rear parts of the film F on the receiver 25 to be sequentially bound from the front and back directions on the upper part of the agricultural products A through the agricultural products. At the same time, the front and rear of this film A are
It is folded inward from the front and back so that it fits tightly against the top of the paper. In this case, the focusing rod portion 871 of the pair of opening/closing rods 87 is
Since the upper part of the clamping plate 67 is horizontally rotated between the front and rear mounting pieces 72, even if the agricultural product protrudes more upwardly than necessary from the receiver 25 due to a shape with a different diameter that is deformed from its original shape, the focusing rod can be rotated horizontally. The portion 87I rotates the film A in a stable manner without damaging the agricultural product A.

Further, the left and right slide bodies 43, 45 are further moved directly below the guide hole 5, and the respective focusing recesses 4g, 49
When the left and right parts of the film F are squeezed and overlapped and further approached, the holding plate 67 of the interlocking frame 60 fixed to the left and right slide bodies 43.45 is interlocked with the respective slide bodies 43.45, and the left and right parts are approached from the direction,
The left and right slide bodies 4
3. The upper and lower parts of the converging part of the film F narrowed to the upper part of the agricultural product A from the left and right directions and the front and rear directions by the converging recesses 4B and 49 of 45 and the converging rod part 87g of the pair of front and rear opening/closing rods 87 can be seen from the left and right. are held at almost the same time, and therefore,
As a whole, the agricultural product A with the cut end B deviated is held by the film F in a state where it is packaged according to its shape.

In addition, when the left and right slide bodies 43 and 45 are approached while further overlapping with the upper and lower portions of the focusing portion of the film F being held between the left and right holding edges 70 and the left and right holding pieces 74, the focusing portion of the film F is The upper and lower parts of the unit are more firmly pressed and clamped in a flat shape from the left and right by the left and right clamping edges 70 and the left and right clamping pieces 74, and the interlocking frames 60 of the left and right slide bodies 43 and 45 are attached to the front and rear coil springs 69. The film F is further advanced along the respective holding plates 67 against this movement, and the left and right interlocking frames 60
The heat-sealed portions 78 of the heater bodies 77 are advanced from the lower portions of the respective clamps 174 toward the condensing portion of the film F, and the left and right heat-sealed portions 78 seal the left and right clamping edges 70 and the left and right clamping pieces 74. A flat press-contact clamping part f1 of the film F in between is clamped from left and right and heat-sealed, and an unnecessary unnecessary film part f3 above the sealing part f2 is removed by fusing.

Therefore, the peripheral sides of the films 1 and F that wrap the agricultural products A are squeezed from the front and back and from the left and right directions through the agricultural products A on the receiver 25, and the agricultural products A are wrapped by the films F. The peripheral side of the film F is bundled and sealed above the agricultural product A, and the agricultural product A is wrapped with the film F covering its entire surface. In addition, since the agricultural products A are supported by the inclined support edge 31 of the annular support portion 30 of the receiver 25 in a shape in which the cut 1-13 is offset from the center, the agricultural products in this state cannot be packaged. The sealed portion 52 of the film F is
It is formed on the upper part of the produce A apart from the cut II B of the produce A, so that the cut II B of the produce A can be easily seen through the film F from the outside.

Next, when the film F is heat-sealed and the piston rod 58 of the cylinder device 57 is contracted, the lower slide body 45 and the upper slide body 43 focus the film F from left and right. The focusing recesses 48 and 49 are opened in the left and right directions, and the pair of opening and closing rods 87 are moved in the evening direction by the pivot axis 85 of the lower slide body 45. By the movement of the pair of opening/closing rods 87, the idle rollers 90 of the respective extension rod portions 87b are sequentially engaged with the release portion 81 from the binding portion 83 of the pair of guide bodies 80 via the inclined guide portion 82. At the same time, the pair of opening/closing rods 87 are gradually rotated about the rotation center axis 85 by the restoring force of the coil spring 92, and each focusing rod portion 871 of the pair of opening/closing rods 87 is The front and rear concentrated hitting parts 87g are separated from the top of the agricultural product A in the front and back direction.The upper and lower slide bodies 43 and 45 are rotated outward in the direction in which they are separated from each other. When the sliding body 43, 45 is slid, the interlocking frame 60 of the slide body 43, 45 is interlocked with it, and the restoring force of the respective coil springs 69 presses the left and right gripping edges 70 against each other and the left and right gripping pieces 74 against each other. While interlocking frame 6
0 is retracted outward along the holding plate 67, and the heat seal portion 78 of the heater integral 77 of the left and right interlocking frames 60
are retreated to the outside of each holding piece 74, and this heat seal portion 78 is spaced outward from the seal portion f2 of the film F. Then, the upper and lower slides F43 and 45 are further slid outward, and the left and right clamping plates 67 are interlocked and retracted outward via their respective interlocking frames 60, and the left and right clamping edges 70 and clamping pieces 74 are widely spaced outward from the sealing portion f2 of the film F, and therefore the left and right holding plates 67 have upper and lower, left and right slide bodies 43, 45, a pair of front and rear opening/closing rods 87, and a clamping piece 74.
are opened widely outward from directly below the guide hole 5 of the support body 4, and are returned to the starting position in preparation for the sealing of the next film F, and the next receiving body 25 advances directly below the guide hole 5. Prepare for.

Further, when the left and right holding plates 67 are separated outward in the left-right direction and air is ejected from the air nozzle 93, the seal part f, the unnecessary film part f that was melted above, and the chips are removed by this air. The unnecessary film portion f and the chips are forcibly removed outwards and are prevented from adhering to the heat seal portion 78 of the heater unit 77.

Next, when the piston rod 58 of the cylinder device 57 is retracted and the film sealing mechanism 40 is returned to the starting position, the electric motor 14 is activated again and the screw punch 12 is rotated in conjunction with the power of the electric motor 14. , the elevator plate 19 is lowered along the screw pestle 12 and the guide rod, and the receiving body 25 carrying the agricultural products wrapped by the film F on the four plates 19 is lowered, and 1 g of the four plates is lowered into a predetermined amount. When the electric motor H is lowered to a position opposite to the second sensor 35 in the lowered position, the second sensor 35 is actuated by this fourth lowering 19, and the operation of the electric motor H is stopped by the output signal of this second sensor 35. And lifting plate 1
9 is stopped, but at this time, when the receiving body 25 is lowered to a predetermined position, one side of the engagement support plate 27 of this receiving body 25 is brought into contact with the operating portion 39 at the upper end of the operating body 37. end,
One side of the engagement support plate 27 is pushed up by the actuating portion 39, and the receiving body 25 having the engagement support plate 27 at the bottom is supported around the support shaft 24 of the column 21 against the coil spring 28. It is rotated downward from the surface 22 toward the front part on the guide slope 23 side. And this receptor 2
5 is rotated approximately 90 degrees and lowered, the packaged agricultural products in the receiver 25 are automatically discharged from the receiver 25 onto the discharge chute 38. It is automatically ejected to the front of the machine.

Further, when the electric motor 14 is operated again, the screw punch 12 is rotated in conjunction, and the receiving body 25 is raised via the nut body 18 and the guide rod, and the engagement support plate 37 of this receiving body 25 is moved to the operating body. 37 and above the operating part 39,
The receiving body 25 is automatically rotated back around the support shaft 24 by the restoring force of the coil spring 28, and this engagement support plate 27 is again engaged with the support surface 22 at the upper end of the column 21, and this receiving body The body 25 is automatically set upward in preparation for receiving the produce A again. Then, as the electric motor 14 continues to rotate, the receiving body 25 is moved upwardly R toward directly below the guide hole 5 of the support body 4, as in the case described above.

〔Effect of the invention〕

According to the present invention, when packaging agricultural products with a film using the film sealing mechanism, the receiver for receiving the agricultural products opens its top surface so that the agricultural products can be received from above! ! (Since it is shaped like a bowl, agricultural products can be easily collected in this container, and the bottom of this container has a downward slope toward one side that supports the lower part of the agricultural products on the top surface.) Since the annular support part that Tr the support edge is integrally provided,
This support edge can support the agricultural products with good stability, and the cut 11 of the agricultural products to be received with the cut 1 on the support edge in the -direction can be placed on one side from the center. This cut can be automatically deflected to
The film sealing mechanism can reliably shift the agricultural product that is sealed to the two parts of the agricultural product from the binding part of the wrapped film. The freshness of agricultural products can be easily checked visually through this cutter without getting in the way.
