Description

The present invention relates to an input device for an object to be packaged, and further relates to an input device for an object to be packaged for inputting an object to be packaged, such as leafy vegetables or rice cake, which is relatively difficult to input into a packaging bag.

For example, leafy vegetables that use edible leaves such as lettuce and spinach are thick and spread out from the root, and they are indefinite shape. It is difficult to put in a bag. An example of a packaging apparatus for putting leafy vegetables and the like as described above into a packaging bag is disclosed in Patent Document 1. Hereinafter, a conventional apparatus for loading an article to be packaged will be described according to the same document.

FIG. 7 is a front view of the packaging device of Patent Document 1. As shown in FIG. 7, the shaping plate 45 retreats and the flexible plate material 46 rises and stops. At the same time, the packaging bag a grasped and suspended by the grasping arm pair 42 moves to the supply position (I). Come and stop. Subsequently, the movable arm tube 44 advances from the retracted position and comes into contact with both sides near the bag mouth of the packaging bag a by the sucker 43, and retracts a little while sucking to widen the bag mouth. Subsequently, the guide tube 52 moves down slightly and the lower end edge is fitted into the bag mouth.

On the other hand, immediately after the rise of the flexible plate material 46 is stopped, the packaged article b such as rice cake and leafy vegetables is pushed into the cylindrical inner space 48 while being pressed against the inner surface of the concave arc of the flexible plate material 46, Is brought into contact with the shutter 51. When the feeding is finished, the horizontal link 49 advances to the right in FIG. 7, and the vertical edges 47 on both sides of the flexible plate 46 are relatively slid on the arcuate inner surface to deform into a small diameter cylindrical shape. The packaged article b fed into the cylindrical inner space 48 is compressed and gripped in a centripetal manner. At that time, the shutter 51 retreats from the lower surface of the cylindrical inner space 48 to the side, and the slider 50 starts to move downward to lower the flexible plate 46 that holds the packaged article b.

The flexible plate member 46 expands the guide cylinder 52 and descends from the bag mouth of the packaging bag a, and the roller shaping plate 45 with the horizontal link 49 slightly retracts when the lowering is finished. In order to loosen the compression, the packaging article b falls by gravity, and at that time, both the packaging bag a and the packaging article b are bitten by the presser piece 53. After the biting operation, the flexible plate member 46 returns to the raised position together with the slider 50, and escapes from the packaging bag a while leaving the packaging article b in the packaging bag a.

Japanese Utility Model Publication No. 56-125803

The packaging device of Patent Document 1 has a problem in that it is difficult to feed the candy, leafy vegetables, and the like, which are packaged articles b, into the cylindrical inner space 48 of the shaping plate 45 from the vertical direction. That is, it is difficult for an operator to look into the cylindrical inner space 48 of the shaping plate 45 for the loading operation due to the peripheral structure of the packaging device, and the packaged article b is correct at a predetermined position of the cylindrical inner space 48. In order to check whether or not it can be put in a posture, it is necessary to look on a stand or the like, and there is a problem that it is difficult to put the packaged article b.

  Moreover, it takes time to put the packaged article b into the packaging bag a because it goes through a plurality of loading processes. That is, in Patent Document 1, the packaged article b is pushed into the cylindrical inner space 48 while being pressed against the inner surface of the concave arc of the flexible plate 46. Thereafter, the horizontal link 49 moves forward, the longitudinal edges 47 on both sides of the flexible plate 46 are relatively slid on the arc-shaped inner surface, deformed into a cylindrical shape, and sent into the cylindrical inner space 48. Embrace b. Thereafter, the shutter 51 is opened, and the packaging article b is lowered into the packaging bag a while the flexible board 46 is holding it, and the roller shaping board 45 that has finished descending is slightly retracted. Since the holding force is loosened, the packaging article b falls and the packaging bag a and the packaging article b are sandwiched by the pressing piece 53. Thereafter, only the flexible plate member 46 returns to the raised position, and the charging of the packaging article b into the packaging bag a is completed.

In view of such problems, the present invention, since the packaging article is loaded from the side, makes it easy for the operator to load the packaging machine, and the loading process is simple. An object of the present invention is to provide an input device for a small number of items to be packaged.

The present invention is an apparatus for loading an article to be packaged into a packaging bag sandwiched between packaging machines, and the apparatus for placing an article for packaging places the article to be packaged on the packaging bag Bending the charging shooter mechanism, which has a flexible charging shooter that can be inserted into a packaging bag and accommodates an article to be packaged, and the charging shooter that is lowered while marking the arc And a guide plate mechanism including a guide plate for guiding the inside of the packaging bag.

According to the present invention, since the loading shooter for placing the article to be packaged descends while arching from the lateral direction, it is easy to place the article to be packaged on the entry shooter at the standby position for placing the article to be packaged. Moreover, since the charging shooter descends while inserting a circular arc from the lateral direction and is inserted into the packaging bag, the charging time is shortened because the charging process is simple.

It is a top view of the charging device.

A rotary wrapping machine 1 shown in FIG. 1 is a conventionally known wrapping machine, and a plurality of sets of two clamp arms 3 are set around a disk-like rotor 2 rotated by a drive motor (not shown). A clamp 5 that clamps the packaging bag 4 is attached to the tip of the clamp arm 3. The rotary wrapping machine 1 is configured to play a role in each section of the rotor 2, and the section (III) shown in FIG. 3 is a section into which an article to be packaged 6 such as leafy vegetables or straw is placed. The section (IV) is a pushing section for pushing the package 6 into the packaging bag 4. Thereafter, although not shown, a sealing section that seals the bag mouth of the packaging bag 4, a cooling section that cools the sealed seal portion, an unloading section that unloads the packaging bag 4 that has been packaged, and the like continue. In addition, this invention is not limited to the rotary packaging machine 1, For example, a linear packaging machine may be sufficient.

On the outer periphery of the charging section (III) of the rotary packaging machine 1, a packaging material charging device 10 is arranged. The input device 10 for an object to be packaged includes an input shooter mechanism 12 that places the object 6 to be packaged on an input shooter 11 and inputs it into the packaging bag 4, and a packaging bag for the item 6 to be packaged stored by the input shooter 11. 4, and a clamping mechanism 14 that clamps only the article 6 to be packaged in the packaging bag 4. Hereinafter, each mechanism will be described.

FIG. 4 is a plan view of the making shooter mechanism 12, and FIG. 5 is a front view of the making shooter mechanism 12. The input shooter mechanism 12 includes an input shooter 11 and is configured to feed the article 6 to be packaged into the packaging bag 4. The input shooter 11 is made of a flexible sheet material, and it is preferable to use a material that quickly returns to its original state even when rolled up, and that is excellent in durability and water resistance, and that the package 6 is easy to slide down. . Specifically, a sheet material in which a polyester (PET) canvas is used as a core and a polyurethane resin or a polyvinyl chloride resin (PVC) is coated on the surface, or a sheet material in which these resins are laminated in layers is used. In addition, a sheet material having a polyester sheet or canvas as a core and a surface coated with a fluororesin, a sheet material having paper as a core and a surface coated with a fluororesin, or the like is used. In addition, a single resin sheet material may be used. Further, in order to reduce friction, fine irregularities may be formed on the surface.

The feeding shooter 11 is formed by bending the longitudinal center portion of a rectangular sheet material made of the above-mentioned material into a U shape, and the tip portion is formed in a large arc shape on the outer side 15 so that the bottom portion of the U shape is formed. Is cut into a semicircular shape to form a notch 16. By forming the leading end portion of the charging shooter 11 in this way, the clamping piece 17 of the clamping mechanism 14 is obstructed by the charging shooter 11 as will be described later. And can be held from the outside of the packaging bag 4. However, the tip of the charging shooter 11 is not limited to such a shape, and only the article 6 to be packaged from the outside of the packaging bag 4 can be obtained without the holding piece 17 of the holding mechanism 14 being obstructed by the charging shooter 11. Any shape that can be sandwiched may be used.

A fixing lever 18 is attached to the outside of the rear end of the charging shooter 11, and this fixing lever 18 is joined to a parallel link mechanism 20 described later via a bracket plate 19. As shown in FIG. 4, the rear end outside of the loading shooter 11 and the arc-shaped fixing plate 18 a of the fixing lever 18 are fixed by screws. The throwing shooter 11 made of a flexible sheet material is curved in a U shape by the arc-shaped fixing plate 18a. Further, a lever 18b protrudes rearward from the fixed plate 18a, and a rear end portion of the lever 18b is inserted into the support tube 18c and fixed by a handle 18d. It is possible to adjust the mounting position of the closing shooter 11 by loosening the handle 18d. The support tube 18 c is fixed to a support portion 19 a that protrudes laterally from the upper end of the trapezoidal bracket plate 19.

The parallel link mechanism 20 is housed in a first mechanical box 21, and as shown in FIGS. 4 and 5, a first rotating shaft 22 is pivotally supported on the upper left side of the rectangular parallelepiped box. A second rotation shaft 23 is pivotally supported at the center inside the rotation shaft 22, and a first link 24 a having a long parallel link 24 is attached to an end of the first rotation shaft 22. A second link 24b having a short parallel link 24 is attached. The first and second links 24a and 24b hang downward, and both lower ends thereof are connected by a connecting link 24c. Further, a link drive cylinder 25 is disposed in the first mechanical box 21 in the longitudinal direction, and a piston rod 25a of the link drive cylinder 25 is connected to the second rotating shaft 23 via a crank lever 26.

The 1st mechanical box 21 which accommodated the said parallel link mechanism 20 is arrange | positioned so that raising / lowering is possible on the 2nd mechanical box 27 shown in FIG. That is, an elevating cylinder 29 is installed in the second mechanical box 27, and the piston rod 28 of the elevating cylinder 29 supports the lower part of the first mechanical box 21, and the first mechanical box 21 moves up and down.

Next, the guide plate mechanism 13 that guides the leading end of the charging shooter 11 into the packaging bag 4 will be described. The guide plate mechanism 13 includes a guide plate 31 that guides the closing shooter 11 and a guide plate cylinder 32 that drives the guide plate 31. The guide plate 31 is a plate body formed in a semi-cylindrical shape, and guides the input shooter 11 to the packaging bag 4 side, and both side edges of the input shooter 11 are pressed against the semi-cylindrical guide plate 31. Accordingly, the flexible charging shooter 11 which is curved is bent into a cylindrical shape as shown in FIG. 4 and can be inserted into the opening of the bag mouth of the packaging bag 4.

1 and 3, one end of the support bracket 33 is joined to the outside of the bottom of the guide plate 31, and the other end is joined to the piston rod 32a of the guide plate cylinder 32 as shown in FIG. ing. Therefore, the guide plate cylinder 32 is in a state of supporting the guide plate 31 upward via the support bracket 33, and when the guide plate cylinder 32 expands and contracts, the guide plate 31 reciprocates in the left-right direction. As will be described later, when the closing shooter 11 moves forward (moves to the right in FIG. 1) and starts the closing operation while drawing a circular arc toward the guide plate 31 by the parallel link mechanism 20, the guide plate 31 moves to the right in FIG. While holding back, the holding shooter 11 is held by the inner wall. Reference numeral 30 denotes a detection sensor attached to the support bracket 33 and detects an object to be packaged between the loading shooter 11 and the guide plate 31.

  Next, the clamping mechanism 14 will be described. After the lower part of the loading shooter 11 is inserted into the packaging bag 4 by the guide plate 31, the holding mechanism 14 sandwiches the package 6 that remains in the loading shooter 11 from the outside of the packaging bag 4, and This is a mechanism for allowing the article 6 to remain in the packaging bag 4 when the is pulled out. This clamping mechanism 14 is disposed at the lower end of the clamp arm 3 in the charging section (III) of the rotary packaging machine 1.

  As shown in FIG. 1, the clamping mechanism 14 includes a clamping hand 14 b on both sides, and the clamping hand 14 b moves toward and away from the air cylinder 35 to clamp the article 6 to be packaged. As shown in FIG. 2, a circular holding piece 14a is attached to the front end of the holding hand 14b, and the pair of holding pieces 14a holds the packaged article 6 from the outside of the packaging bag 4. The holding piece 14a The interval at which the sandwiching pieces 14a approach is adjusted according to the object to be packaged 6 so that the object to be packaged 6 is not damaged by pressure contact. Adjustment of the space | interval of this clamping piece 14a can be adjusted by adjusting the attachment position to the clamping hand 14b. As shown in FIG. 1, the approaching position of the clamping piece 14 a is adjusted so as to come directly below the clamp 5 of the clamp arm 3.

Next, the pushing mechanism 36 arranged in the pushing section (IV) will be briefly described. This push-in mechanism 36 is a conventionally known mechanism, and the article 6 to be packaged is put into the packaging bag 4 by the throwing shooter 11, and the article 6 staying in the packaging bag 4 is further packaged by the clamping mechanism 14. This is a mechanism for completely storing in the bag 4, and the hook-shaped push rod 37 descends from the top to push the article 6 in the packaging bag 4, and the wire-like opening / closing rod 38 moves the bottom of the packaging bag 4. Both sides are pressed and released to improve the fit of the package 6.

Next, the use state of the said structure is demonstrated using FIGS.
Before the packaging bag 4 having an open bag mouth arrives at the loading section (III) in FIG. 3, the operator places the packaged item 6 on the loading shooter 11 and waits. Since the piston rod 28 of the elevating cylinder 29 during the standby state is in an extended state, the first mechanical box 21 is at the highest position.

As described above, when the first mechanical box 21 is in the raised position, the throwing shooter 11 is also in the high position. At that time, the loading shooter 11 is inclined downward toward the rotary packaging machine 1 at an angle of about 30 degrees from the horizontal. The angle of the charging shooter 11 during the standby is preferably an angle at which the article 6 can be easily placed. Specifically, an angle in the range of about 45 degrees from the horizontal is preferable. The angle at the time of loading from the lateral direction by the loading shooter 11 refers to an angle at which an object to be packaged can be easily placed on the loading shooter 11 as described above.

During standby, the piston rod 25a of the link drive cylinder 25 is in a contracted state, and the parallel link 24 composed of the first and second links 24a, 24b is substantially V upward as shown by phantom lines in FIG. It expands in a letter shape. At this time, since the connecting link 24c is inclined about 60 degrees to the upper right, the bracket plate 19 attached to the connecting link 24c is inclined about 60 degrees to the left in FIG. For this reason, the closing shooter 11 fixed to the bracket plate 19 via the fixing lever 18 is inclined downward at an angle of about 30 degrees as indicated by a virtual line, and the tip of the closing shooter 11 at this time As shown in FIG. 6A, the portion is in a semi-cylindrical guide plate 31, and the tip is bent into a truncated cone shape by the guide plate 31. As shown in FIGS. 6A and 6B, even if the inclination angle of the charging shooter 11 is increased and the package 6 is about to slide down, it is blocked by the guide plate 31 and does not fall.

When the piston rod 25a of the link drive cylinder 25 extends, as shown in FIG. 5, the second rotating shaft 23 rotates counterclockwise via the crank lever 26, and the second link 24b also rotates counterclockwise. In addition, the first link 24 a whose lower ends are connected by the connecting link 24 c also rotates counterclockwise about the first rotation shaft 22. Simultaneously with the start of extension of the piston rod 25a of the link drive cylinder 25, the elevating cylinder 29 starts to contract, and the first mechanical box 21 and the closing shooter 11 start to descend. Accordingly, as shown in FIG. 6B, the input shooter 11 inclines while drawing a circular arc on the right side and descends while being guided by the inner wall of the guide plate 31. As described above, even if the loading shooter 11 advances to the guide plate 31 side, the guide plate 31 escapes horizontally to the rotary packaging machine 1 side by the guide plate cylinder 32, but the loading shooter 11 does not move to the guide plate 31. Descend while following

In the state where the piston rod 25a is extended to the longest, the lower ends of the first and second links 24a, 24b move to the right, and the connecting link 24c connecting the lower ends of the first and second links 24a, 24b is horizontal. It becomes. The bracket plate 19 fixed to the connection link 24c rises as shown by the solid line in FIG. The closing shooter 11 fixed to the bracket plate 19 via the fixing lever 18 is in a vertical state in the guide plate 31 as shown in FIG. Further, when the first mechanical box 21 is lowered by the piston rod 28 of the lifting cylinder 29, the charging shooter 11 erected vertically is lowered, and the lower part of the charging shooter 11 is inserted into the packaging bag 4.

As shown in FIG. 6 (B), the packaged item 6 that has been prevented from dropping by the guide plate 31 until the charging shooter 11 stands up is blocked as shown in FIG. 6 (C). Therefore, it falls into the packaging bag 4 or stays at the tip of the charging shooter 11. When the input shooter 11 is restored to the original state in the above-described stage, the package 6 that spreads upward like leafy vegetables is lifted together with the input shooter 11, and in the worst case, the packaging is performed. There is a risk of jumping out of the bag 4. Therefore, when the article 6 to be packaged falls to the inside of the packaging bag 4 or the leading end of the loading shooter 11, the clamping mechanism 14 is actuated so that the clamping piece 14a of the clamping hand 14b comes close to be packaged from the outside of the packaging bag 4. The object 6 is clamped. After the article to be packaged 6 is clamped by the clamping piece 14a, the parallel link mechanism 20 and the lifting cylinder 29 operate in the reverse manner to pull out only the charging shooter 11 from the packaging bag 4, and in the charging section (III) Is finished.

The packaging bag 4 that has been loaded is moved to the pushing section (IV) by the rotation of the rotor 2, but the detection sensor 30 detects whether there is a loading mistake of the package 6. In this push-in section (IV), the package 6 is pushed into the packaging bag 4 in a good posture when the package 6 is not sufficiently charged in the loading section (III). As for the push-in mechanism 36, as described above, when the article 4 reaches the push-in section (IV), the bowl-shaped push rod 37 descends from the top of the bag mouth to push the article 6 into the packaging bag 4. The opening / closing rod 38 opens and closes, and the bottom of the packaging bag 4 is pressed and released from the left and right sides so that the article 6 to be packed fits to the bottom of the packaging bag 4. In this way, the packaging bag 4 in which the article to be packed 4 is sufficiently pushed in the pushing section (IV) is moved to the sealing section of the rotary packaging machine 1 and sealed. Carry out of the packaging machine and complete the packaging.
The closing shooter mechanism 12 includes a parallel link mechanism 20 that rotates the closing shooter 11 while drawing an arc, and a lift cylinder 29 that moves the parallel link mechanism 20 and the closing shooter 11 up and down. The present invention is not limited to such a configuration as long as it is a mechanism that lowers the input shooter 11 while drawing an arc. For example, the input shooter 11 may be moved along the guide groove.
Moreover, in the said embodiment, although the pinching mechanism 14 for arrange | positioning the to-be-packaged product 6 to remain in the packaging bag 4 was arrange | positioned in the front-end | tip lower part of the clamp arm 3 of the input section (III), This clamping mechanism 14 is not necessarily required. That is, when pulling out the loading shooter 11 from the inside of the packaging bag 4, for example, carrots and radishes, such as carrots and radishes, follow along with the loading shooter 11 and do not have to be packaged. Also good.

INDUSTRIAL APPLICABILITY The present invention is useful for an input device for an object to be packaged that inputs an object to be packaged such as leafy vegetables and rice cake, which is relatively difficult to input into a packaging bag.
