This invention relates to a packaging method and apparatus for supplying an elongated plant between finger claws running in the same direction at a predetermined interval, and then inserting the elongated plant into an open film for packaging.

(Prior art) When conventionally packaging long green onions, etc. using a horizontal and row packaging machine, the roots of a plurality of long green onions are placed backwards in the direction of travel, and a pair of cross-sections are separated slightly in the center. The rear end of the root of the long leek is fed onto the L-shaped conveyance guide plate, connected to a pair of endless chains disposed on both sides of the guide plate, and protruded upward from the center of both guide plates. The leek was pushed forward, and the eastern front end of the leek was inserted into a bag making machine for packaging.

In this way, the reason why the root part was positioned backward in the direction of movement is that the finger claw pushes the root part from behind to position the green onion to the packaging machine. If the tip is placed in the
In addition, if the tip of the flange is open and part of it protrudes behind the finger nail, it will get caught in the sealing part during the subsequent horizontal sealing of the packaging, making it impossible to pack correctly and resulting in defective packaging. This is because it may cause. Therefore, it was necessary to press the root part at the rear in the direction of travel, but in this case, when inserting the green onion into the bag-making machine, the eastern part was open, so it hit the entrance end of the bag-making machine and fell into the bag-making machine. There were cases where the product was not inserted correctly, resulting in defective packaging.

(Problems to be Solved by the Invention) The present invention has been made to solve the above-mentioned problems, and its purpose is to remove the roots of long onions, chives, and other slender plants without damaging their leeks. It is an object of the present invention to provide a packaging method and device that can correctly maintain a predetermined interval and insert into an opened film, thereby eliminating the packaging defects that occur in the past.

(Means for Solving the Problems) In order to achieve the above object, according to the method of the present invention, an elongated plant is supplied between finger claws that run at a predetermined interval in the same direction as the conveyance direction of the packaged object. Then, in a packaging method in which the slender plant is inserted into an open film and packaged, the slender plant is fed between the finger claws with its root side forward, and the transport speed of the slender plant is controlled by the movement of the finger claws. The tip of the root of the slender plant is pressed against the fingernail at a higher speed than the above speed, and then inserted into the film.

Moreover, the apparatus of the present invention for carrying out the above method is a carrier for transporting an elongated plant as an object to be packaged.

a step, a plurality of finger claws running at predetermined intervals in the same direction as the conveying means, a bag-shaped opening forming means for a packaging film disposed on the front end side in the traveling direction of the conveying means, and the bag. In a packaging device comprising longitudinal sealing and transverse sealing means for a packaging film provided in front of the shaped opening forming means in the traveling direction, and a cutter means for cutting the transverse sealing portion of the packaging film, Means for accelerating the conveyance speed of the plant relative to the moving speed of the fingers is provided, and the front end of the elongated plant is pressed against the front finger at the rear in the traveling direction of the bag-shaped opening forming means. .

Preferably, the conveying means is formed of a series of roller groups rotatably mounted between a pair of endless chains, and the accelerating means is in contact with a lower part of the roller group to direct the roller group forward in the conveying direction. It is constituted by a rotational force imparting member that is rotated by a rotational force.

(Embodiments) Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

The apparatus of the present invention is an improvement on the known packaging apparatus, and the main part thereof is the improvement of the part for inserting the articles to be packaged into the bag making machine while maintaining a predetermined interval.

FIG. 1 shows the above-mentioned main parts of the present invention, and 1 indicates an endless chain. A pair of chains 1 are provided on the left and right, and each chain is engaged with a sprocket 2-2 after sprouting in the direction of the arrow. It is designed to run. As shown in FIG. 2, rotatable rollers 3-3 are provided across the pair of left and right chains 1-1. This rotatable roller
3 consists of a shaft part 3a and a roller part 3b, and its structure is that the shaft part 3a and the roller part 3b are integrally formed, and the shaft part 3a is rotatably connected to the chain 1. Alternatively, the shaft portion 3a may be fixed to the chain 1 and the roller portion 3b may be rotatable with respect to this shaft portion 3a. The rotatable rollers 3 are arranged in groups at predetermined intervals, and between the rotatable roller groups, finger pawls 4 project upward and are attached to the chain 1. The intervals between these finger claws 4-4 are relatively large, and a long slender plant 5 such as a green onion to be packaged is placed between these finger claws 4-4, placed on the rotatable roller 3, and conveyed. It has become. This slender plant 5
The interval between the finger nails 4-4 is made sufficiently longer than the length of the elongated plant 5 in order to facilitate the operation of inserting the plant between the finger nails 4-4. In order to prevent the long plants 5 to be packaged from spreading laterally on the rotatable roller 3-3, a horizontal guide frame 6 is provided, which is slightly separated upward from the roller 3-3. -6 is roller 3
-3 is provided on the left and right sides.

In the above device of the present invention, a pair of left and right guide rails 7 is provided at the lower part in front of the chain 1-1 in the running direction, and as the chain 1-1 runs, the lower surface of the rotatable roller 3-3 attached thereto. The guide rail 7-7 is configured such that the upper surface of the guide rail 7-7 comes into pressure contact with the upper surface of the guide rail 7-7. When the lower surface of the roller 3-3 comes into contact with the guide rail 7-7, the frictional resistance between the rollers 3-3 and the guide rail 7 causes the roller 3-3, which has come into contact with the guide rail 7, to move toward the chain 1 as shown in FIG. It rotates in the same direction as the running direction of -1.

A bag making device 8 is provided adjacent to the front end of the chain 1-1. This bag-making device 8 is generally used in known horizontal and row packaging machines, and is shaped like a bag by folding a packaging film 9 supplied from below so that both ends of the packaging film 9 are brought together in the shape of palms facing upward. That is. An endless belt 10 is provided at the entrance of the bag-making device 8, and as described later, this allows the confectionery part that spreads upward of the elongated plant 5, which is the object to be packaged, to smoothly enter the bag-making device 8. This is to guide the presser foot so that it can be pressed. A vertical sealing device 11 is provided in front of the bag making device 8 for vertically sealing the upper end of the packaging film 9 that is joined together in the shape of palms. However, a known transverse seal cutting device is provided in the transverse plastic packaging machine.

The above-mentioned device of the present invention was specially developed for packaging long and slender plants 5 such as long onions, and the packaging method will be described first. When putting in the elongated plant 5, its root part 5a is positioned at the front in the advancing direction. As a result, the elongated plant 5 is placed on the rotatable roller 3 installed between the chains 1-1, and the front and rear finger claws 4
-4, and is transported forward at an intermediate position. When the chain 1-1 travels forward in this manner and comes to the position of the guide rail 7-7, the roller 3 carrying the elongated plant 5 rides on the guide rail 7-7. At this time, as the chain 1-1 travels, the roller 3 rotates forward in the traveling direction due to frictional resistance with the guide rail as shown by the arrow in FIG.

As a result, the elongated plant 5 on this roller moves forward with respect to the running chain 1-1, and its root tip comes into contact with the finger claw 4. In this way, the elongated plants 5 that are sequentially fed into the bag making machine 8 by the conveyance chain 1-1 have their root tips attached to the finger nails 4.
It is kept in the correct position with a predetermined spacing. The slender plant 5 is then cut into a bag making machine 8 from its root.
However, since there is an endless belt 10 above this bag making machine 8, if the eastern part of the belt protrudes upward, push it down to enter the bag making machine. Make it easier.

The II plant 5 that has entered the bag-making device 8 in this way is then moved forward together with the packaging film 9 while maintaining the correct position at the above-mentioned predetermined distance, and is then sealed by a vertical sealing device using a known method. The upper edge is vertically sealed, then laterally sealed and cut to obtain an elongated plant package entirely covered with the film 9.

As described above, in the above embodiment of the present invention, the rotatable roller 3 and the guide rail 7 are used as means for pressing the elongated plant 5 against the finger claw 4 in front of it, but various other methods may be adopted. I can do it. As an example, an endless belt is provided in place of the guide and rail 7 in the above embodiment, and the upper surface of this endless belt is brought into contact with the lower surface of the rotatable roller 3, and this endless belt is moved oppositely to the running of the chain 1-1. It may also be driven in the direction. Alternatively, an endless belt may be installed at the upper end of the rotatable roller, with the lower surface of the belt in contact with the upper end surface of the roller, and the belt may be driven in the same direction as the chain travels. Alternatively, the guide rail may be abolished, and an endless belt may be provided above the rotatable roller 3, and the lower surface of the endless belt may contact the upper surface of the fine plant 5 that is being transported. While pressing against the rotatable roller, the rotatable roller may be rotated by its FJ friction force, thereby pressing the elongated plant against the finger nails 4 in front of it. Furthermore, the rotatable roller 3 and the guide rail 7 are eliminated, and a belt conveyor that moves slightly faster than the pair of endless chains 1-1 is provided between the pair of endless chains 1-1, and the long and narrow plants placed on the belt conveyor are transferred between the endless chains. It may be pressed by the finger claws provided. In the illustrated embodiment, the finger claw 4-4
Rotatable rollers 3-3 are provided over the entire surface of the mutual roller, but it is not necessary to provide this many rollers 3-3, and some of these rollers may be replaced with flat plates. However, the number can also be reduced. The point is that when the rotatable roller 3-3 is rotated by the guide rail 7-7, the elongated plant placed thereon should be moved forward so as to come into contact with the front finger nail.

(Effects) As described above, in the method for packaging slender plants according to the present invention, the slender plants are fed between the finger claws with their roots facing forward, and the transport speed of the slender plants is set higher than the moving speed of the finger claws. Since the tip of the root of the slender plant is quickly pressed against the finger nail and then inserted into the opened film, the eastern part of the slender plant is at the entrance when entering the bag-like opening forming means such as a bag making machine. It is inserted smoothly without getting caught, and the tip of the root comes into contact with the finger nail and is maintained at a predetermined interval, so the predetermined interval is maintained even in the film formed into a bag shape, and during subsequent horizontal sealing and cutting. The tip of the elongated plant no longer protrudes from the seal portion. Furthermore, since the tip of the root is pressed against the finger claw, the alignment is more reliable than when the eastern part is pressed against the finger claw for alignment.

Furthermore, in the apparatus of the present invention for achieving the above method, a means for simply accelerating the conveyance speed of the elongated plant relative to the moving speed of the finger claws is provided to form a bag-like opening in a bag making machine or the like. Since the front end of the plant can be pressed against the front finger claw at the rear in the direction of movement of the means, the structure can be simplified and the operation can be ensured.

In particular, the conveying means comprises a series of roller groups rotatably mounted between a pair of endless chains, and the accelerating means contacts the lower part of the roller group to rotate the roller group forward in the conveyance direction. In the case where the rotating force imparting member is used, there is no need to separately run another belt conveyor or the like between the endless chains to which the finger claws are attached, and the drive mechanism can be simplified.

The rear end of the root of this long leek is fed forward by finger claws that are connected to a pair of endless chains placed on both sides of this guide plate and protrude upward from the center of both guide plates. The green onions were then packaged by being inserted into a bag making machine from the front end of the green onion leaf. In this way, the reason why the root part was positioned backward in the direction of movement is that the finger claw pushes the root part from behind to position the green onion to the packaging machine, and the eastern part is positioned backward. If you place it in the wrong position, the tip will be soft and may bend and damage the packaged item.
In addition, if the tip of the eastern part is open and a part of it protrudes behind the finger claw, it will get caught in the seal part during the horizontal sealing in subsequent packaging, making it impossible to package correctly and causing defective packaging. This is because it would become . Therefore, it was necessary to position the root part at the rear of the bag-making machine and push it forward, but in this case, when inserting the green onion into the bag-making machine, the eastern part was open, so it hit the entrance end of the bag-making machine and fell into the bag-making machine. There were cases where the product was not inserted correctly, resulting in defective packaging. (Problems to be Solved by the Invention) The present invention has been made to solve the above-mentioned problems, and its purpose is to remove the roots of long onions, chives, and other long, slender plants without damaging their eastern parts. It is an object of the present invention to provide a packaging device that can correctly maintain a predetermined interval and insert into an opened film, and can eliminate the packaging defects that occur in the past.

The front end of the elongated plant is pressed against the front finger at the rear in the traveling direction of the bag-shaped opening forming means. Preferably, the conveying means is formed of a series of roller groups rotatably mounted between a pair of endless chains, and the accelerating means is in contact with a lower part of the roller group to direct the roller group forward in the conveying direction. It is constituted by a rotational force imparting member that is rotated by a rotational force. (Embodiments) Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. The apparatus of the present invention is an improvement on a known packaging apparatus, and the main part thereof is an improvement in the part where the articles to be packaged are inserted into the bag making machine while maintaining a predetermined interval. FIG. 1 shows the above-mentioned main parts of the present invention. Reference numeral 1 indicates an endless chain, and a pair of chains 1 are provided on the left and right sides, and each chain is engaged with the front and rear sprockets 2-2 and moves in the direction of the arrow. It is designed to run. As shown in FIG. 2, rotatable rollers 3-3 are provided across the pair of left and right chains 1-1. This rotatable roller 3
consists of a shaft portion 3a and a roller portion 3b, and its structure is such that the shaft portion 3a and roller portion 3b are integrally formed and the shaft portion 3a is rotatably connected to the chain 1. Alternatively, the shaft portion 3a may be fixed to the chain 1 and the roller portion 3b may be rotatable with respect to this shaft portion 3a. The rotatable rollers 3 are arranged in groups at predetermined intervals, and between the rotatable roller groups, finger pawls 4 project upward and are attached to the chain 1. The intervals between these finger claws 4-4 are relatively large, and an elongated plant 5 such as a green onion to be packaged is placed between these finger claws 4-4, placed on the rotatable roller 3, and conveyed. It looks like this. This slender plant 5
The interval between the finger nails 4-4 is made sufficiently longer than the length of the elongated plant 5 in order to facilitate the operation of inserting the plant between the finger nails 4-4. Further, in order to prevent the elongated plant 5 to be packaged from spreading laterally on the rotatable roller 3-3, a horizontal ten-shaped guide frame 6- is slightly separated upward from the roller 3-3. 6 is roller 3-3

The guide rail 7-7 is configured such that the upper surface of the guide rail 7-7 comes into pressure contact with the upper surface of the guide rail 7-7. When the lower surface of the roller 3-3 comes into contact with the guide rail 7-7 in this way, the frictional resistance between the rollers 3-3 and the guide rail 7-7 causes the roller 3-3, which has come into contact with the guide rail 7-7, to become chain It rotates in the same direction as the running direction of 1-1. A bag making device 8 is provided adjacent to the front end of the chain 1-1. This bag making device 8 is generally used in a known horizontal billow packaging machine, and is made into a bag shape by folding a packaging film 9 fed from below and bringing both ends of the film together in the shape of palms facing upward. It is something to do. An endless belt 10 is provided at the entrance of the bag making device 8, and as described later, this enables the upwardly extending eastern part of the elongated plant 5, which is the object to be packaged, to smoothly enter the bag making device 8. This is to guide the presser foot. In front of this bag-making device 8, a vertical sealing device 11 is provided which vertically seals the upper end of the packaging film 9, which is folded together in the shape of palms. However, the horizontal billow packaging machine is equipped with a known horizontal seal cutting device. The above-mentioned device of the present invention was specially developed for packaging long and slender plants 5 such as long onions, and the packaging method will be described first. When putting in the elongated plant 5, its root part 5a is positioned at the front in the advancing direction. As a result, the elongated plant 5 is placed on the rotatable roller 3 installed between the chains 1-1, and the front and rear finger claws 4
-4 and is transported forward at an intermediate position. When the chain 1-1 travels forward in this manner and comes to the position of the guide rail 7-7, the roller 3 carrying the elongated plant 5 rides on the guide rail 7-7. At this time, as the chain 1-1 travels, the roller 3 rotates forward in the traveling direction due to frictional resistance with the guide rail as shown by the arrow in FIG. As a result, the elongated plant 5 on this roller moves forward with respect to the running chain 1-1, and its root tip comes into contact with the finger claw 4. In this way, the elongated plants 5 that are sequentially fed into the bag making machine 8 by the conveyance chain 1-1 have their root tips attached to the finger nails 4.
It is kept in the correct position with a predetermined spacing. The slender plant 5 is then cut into a bag making machine 8 from its root.
