Description

DETAILED DESCRIPTION OF THE INVENTION Purpose of the Invention (Industrial Application Field) The present invention is directed to, for example, cutting a cylindrical film to a predetermined length and sealing the cut portion to form a bag shape.
In a bagging and packaging machine for fruits and vegetables, etc., which expands the opening of the packaging bag, inserts the contents from there, ties the opening, and discharges the bag, the contents are packed in the packaging bag with as little space as possible. This relates to devices that are packed tightly together.

(Prior art) Conventionally, as this type of bagging and packaging machine, for example,
There is one described in Japanese Patent No.-174413. In this packaging machine, as shown in FIG. A pair of clamp parts (support arm 43, rotation arm 44) that can be opened and closed
, a fixed clamp plate 46, a movable clamp plate 48, and the like.

A plurality of packaging bag transfer members 42 are installed at equal intervals, and each plug device, which is responsible for one step of packaging work, is used to open a cylindrical film that has been previously formed into a cylindrical shape into a bag shape. Both ends of the cylindrical bag are connected to the clamp portions 43, 44, 46.
A holding/drawing device A that grips and pulls out the cylindrical film at 48, and a seal cutting device that cuts the cylindrical film pulled out from the holding/drawing device A into a predetermined length and seals the cut portion to form one packaging bag 77. B, and both clamp parts 43, 44 so as to open and close the opening 78 of the packaging bag 77 sent from the seal cutting device B by the transfer member 42.
, 46. A bag mouth opening/closing device C that opens and closes 48, seals the mouth 78 of the packaging bag 77 sent from the bag mouth opening/closing device C by the transfer member 42, and seals the sealed packaging. The bag 77 is attached to the clamp parts 43 and 44 of the transfer member 42.
．． so as to synchronize the movement of the transfer member 42 with the rotation of both main chains 4, respectively, and a closing grip release device for releasing the grip of the clamp parts 43.44, 46.48 so as to move the clamp parts 43.44, 46.48 1liltllR from 46.48. By sequentially arranging the devices along the main lane 4, the various devices A, B, C, and D can effectively cooperate to perform continuous operation.

In particular, a bag opening/closing device C (unexamined Japanese Patent Application Publication No. 2003-120000) opens and closes both clamp portions 43, 44, 46, and 48 so as to open and close the opening 78 of a packaging bag 77 sent from the seal cutting device B by the transfer member 42. As shown in Figs. 15 and 16, a base plate 83 installed in the vicinity of the front lower sprocket 82 of the sprockets on which the main chain 4 is wound, A guide member 84 is provided upright between the left and right main chains 4 along the moving direction of the transfer member 42, and its lower end is rotatably mounted on a shaft 85. This guide member 84 consists of left and right guide rods 86, and a plate 87 for preventing the stored object from being captured, which is installed between the guide rods 86 except for the entrance portion 86a at the lower end and the exit portion 86b at the upper end. A guide surface 88 is formed along the longitudinal direction of both guide rods 86, and the distance between the guide surface 88 and the movement locus of the transfer member 42, that is, the distance from the main chain 4 is determined near the inlet portion 86a and the outlet portion 86b. Narrow and wide between them. When the operating rod 89 connected to the inside of the steady rest plate 87 is operated, the guide member 84 tilts within a certain angle range about the shaft 85 at its lower end, as shown by the imaginary line in FIG.

Engagement protrusions 90 are provided at the distal ends of both rotating arms 44 of the transfer member 42 to protrude inward.

When the transfer member 42 moves upward along the main chain 4, the engaging protrusion 90 enters the entrance portion 86a of both guide rods 86 and comes into contact with the guide surface 88, as shown in FIG. As 42 rises, it comes into contact with this guide surface 88 and is restricted in its guidance.

That is, as the distance gradually increases, the rotating arm 44b of the transfer member 42 is forcibly opened against the support arm 43 against the biasing force of the spring 62, as shown in FIG. Both side clamp portions 43 of the transfer member 42.
44, 46, and 48 are opened from the closed state, and the opening 78 of the packaging bag 77 is opened. At this time, the contents are supplied to the opened packaging bag 77. When the distance is gradually narrowed at the outlet portion 86b after the contents are supplied, the rotating arm 44 gradually closes with respect to the support arm 43 due to the bias of the spring 62.
Both clamping parts 43, 44, 46, 48 are closed again. In addition, when adjusting the opening width of the packaging bag 77, the operating rod 89 is operated to adjust the tilting of the guide member 84 as described above.

(Problems to be Solved by the Invention) However, in the bag opening/closing device C, the contents are simply put into the expanded packaging bag 77 and the opening 78 is tied, so that the contents are not easily removed. If the packaging bag 77 is not packed securely, the accommodation portion 79 of the packaging bag 77 may become loose after binding, resulting in poor packaging conditions.

Therefore, the present invention applies vibration to the packaging bag containing the contents.

Structure of the Invention (Means for Solving the Problems) That is, the present invention, as shown in the drawings of the embodiment described later, hits the packaging bag 77 suspended and supported by the transfer members 42A, 42B, 420. diaphragm 71 and this diaphragm 7

and a rotating arm 44 are supported at their upper ends by a shaft 45 so as to be rotatable in the front-rear direction, and a fixed clamping plate 46 is installed between both support arms 43 and between the rotating arms 44 so as to extend in the left-right direction. At the same time, a pair of bifurcated movable clamping plates 48 are each supported on a guide shaft 47 which is supported on the upper surface of both fixed clamping plates 46 so as to extend in the left-right direction. ing. The clamping arm 49 of each movable clamping plate 48 extending downward from the inside of the guide shaft 47 is adapted to abut on the inside of the fixed clamping plate 46 .

A cam roller 51 is supported by a slide shaft 52 on a movable arm 50 of each movable clamping plate 48 extending from the guide shaft 47 to the outside of the fixed clamping plate 46 .
0 moves in the left-right direction along the guide shaft 47, the cam roller 51 also moves along the slide shaft 52 along with the movable arm 50.
It is designed to move left and right along the . Both left and right ends of the slide shaft 52 are biased by a spring 53, and due to this bias, the clamp K149 of the movable clamp plate 48 and the fixed clamp plate 46 are always closed. The support arm 432, the rotating arm 44, the fixed clamping plate 46, the movable clamping plate 48, etc. constitute a clamp section. A support shaft 54 is protruded from the upper part of the support arm 43, and a guide roller 55 is supported at the center thereof, and the tip of the support shaft 54 is removably engaged with the support recess 8 of the support claw 7 of the main chain 4. Support pin 5 supported by

The transfer member 42C is supported by the support pawl 7 by the support pin 56, and moves upward toward the front chain wheel 2 by the rotation of the main chain 4, and then the support pawl 7 is moved as shown by the imaginary line in FIG. Front chain wheel 2
When reaching the top, the transfer member 42 is moved as shown by the imaginary line in FIG.
The guide roller 55 of C is connected to the guide groove 9a of the idle rail 9.
be placed on top. Roughly speaking, as the main chain 4 rotates, the guide roller 55 rolls on the guide groove 9a, and the support pin 56 moves along the guide groove 9a to draw a movement locus L (see FIG. 8). When the support shaft 54 of the guide roller 55 hits the third feed pawl 14, the feed pawl 14 tilts backward about the shaft 15 against the bias of the spring 16, as shown by the imaginary line in FIG. The support pin 56 advances further. As shown by the solid line in FIG.
By the time the support claw 7 moves next to the front chain wheel 2 and the front chain engagement plate 5, it moves diagonally downward so as to draw a movement trajectory M along the main chain 4 between the front chain wheel 2 and the front chain engagement plate 5, and follows both movement paths. Since the distance between M is widened, the support pin 5
6 can be handled upward from the support recess 8 of the support claw 7, and the transfer member 42C shown in FIG. At this time, the pressing roller 61 of the transfer member 42C is pressed against the guide surface 35 of the guide rod 34.

It runs parallel to the main chain 4 between them. At this time, the spindle 5
As shown in FIG. 9, since the guide rod 34 moves along a movement trajectory N parallel to the horizontal portion 35b of the guide groove 35, the distance between the front inclined portion 35a and the support shaft 54 gradually increases. spread. As a result, the pressure roller 6 of the transfer member 42C
1 is moved from the front inclined portion 35a to the horizontal portion 35b and is pushed downward, so that both links 57.5 of the transfer member 42C
8 opens against the bias of the spring 62, and accordingly, the support arm 43 and the rotating arm 44 also open. Third feed claw 14
The support shaft 54 of the transfer member 42C is connected to the third stopper 4 part 23a.
Once inside, it stops together with the other feed claws 12, 13, and the transfer member 42C stops here. In addition, lever 1
7, the third stopper plate 26 touches the other stopper plate 2.
4.25 protrudes onto the guide rail 9, and even if the support shaft 54 of the transfer member 42G passes through the third stopper recess 23a due to inertia, it is stopped by the third stopper plate 26.

The above describes how one transfer member 42G changes from the state shown in FIG. 1 to the state shown in FIG. 5 to the state shown in FIG. 9. However, another transfer member 42B shown in FIG. 9th
It is in the same state as the transfer member 42C shown in the figure, and moves to the position shown in FIG. 5 by the same action as the transfer member 42G.

Then, the transfer member 42B shown in FIG. 5 is hoisted until it reaches the state shown in FIG. 9. When the lever 17 tilts backward as shown in FIG. 9, each of the feed pawls 12, 13, and 14 moves backward together with the slide rod 11, and as shown in FIG. 13, the guide roller 55 rolls on the guide groove 98, and as shown in FIG. move on. At this time, since the movement locus N of the support shaft 54 and the horizontal portion 35b of the guide surface 35 of the guide rod 34 are parallel, the pressing roller 61 of the transfer member 42B
5b, the support arm 43 and the pivot arm 44, together with both links 57, 58, are open. The second feed claw 13 is opened at the point where the support shaft 54 of the transfer member 42[3 enters the second stopper portion 22].
14, and the transfer member 42B stops here. Note that the second stopper plate 25 also has the third stopper plate 26.
plays a similar role.

This transfer member 42B shown in FIG. 9 is in the same state as the transfer member 42A shown in FIG. 5, and this transfer member 42A moves to the position shown in FIG. Moving.

Next, a description will be given of how the transfer member 42A shown in FIG. 5 reaches the state shown in FIG. 9. When the lever 17 is tilted backward as shown in FIG.
2.13.14 moves backward, and as shown in FIG. 10, the support shaft 54 of the transfer member 42A is pushed backward by the second feed claw 12, and the guide roller 55 moves along the guide groove 9a. As shown in FIG. 11, the support pin 56 advances parallel to the main chain 4 between the front and rear cylindrical chain engagement plates 5 and 6. At this time, the distance between the movement trajectory N of the support shaft 54 and the rear inclined portion 35C of the guide surface 35 of the guide rod 34 gradually becomes narrower. As a result, the pressure roller 61 of the transfer member 42A moves from the horizontal surface 35b of the guide surface 35 to the rear oblique portion 35c, and the pressure on the roller 61 is released, so that both links 57 and 58 of the transfer member 42A are moved by the spring. The support arm 43 and the rotating arm 44 are closed by the biasing force of the arm 62.
Also close. The third feed claw 12 is the support shaft 54 of the transfer member 42A.
When it enters the first stopper recess 2Ia, it stops together with the other feed claws 13, 14, and the transfer member 42A stops here. Note that the first stopper plate 24 also plays the same role as the third stopper plate 26.

In this way, when the transfer member 42A moves to the position shown in FIG. 9, the support claw 7 of the main chain 4, which has once separated from the support pin 56 of the transfer member 42G as shown in FIG. 8, moves as shown in FIG. The transfer member 42A is approached as shown in FIG. This support claw 7 moves obliquely upward so as to draw a movement trajectory M along the main chain 4 between the rear chain engagement plate 6 and the rear chain wheel 3, so this movement trajectory M and the transfer member 4
The distance from the movement locus of the support pin 56 of 2A gradually becomes narrower, and as shown in FIG. 12.13, this support pin 56
is engaged with the support recess 8 of the support claw 7 from above, and the ninth
The transfer member 42A shown in the figure is supported by the main chain 4 again. Before this support, the lever 17 bends its head, and each feed pawl 12, 13, 14 moves forward together with the slide rod 11, and each stopper plate 24, 25, 26 moves forward on the guide rail 9.
Evacuate from above to below.

Thereafter, the transfer member 42A shown in FIG. 9 moves upwardly through the rear chain wheel 3 due to the rotation of the main chain 4, and the transfer member 42A shown in FIG.
Only 2B and 42C remain.

At the same time, the next transfer member (not shown) is sent below the front chain wheel 2, and is in the same state as each transfer member 42A, 42B, 42C shown in FIG. ends. Thereafter, each step is repeated with the same effect.

A steady rest roller 63 is supported by a shaft 63a at the lower part of the support arm 43 of each transfer member 42A, 42B, 420, and rolls on a guide plate 64 provided along the main chain 4. There is.

Further, in each of the transfer members 42A, 42B, and 42C, the opening between the support arm 43 and the rotating arm 44 can be adjusted by rotating the operating rod 36 to move the guide rod 34 of the re-guide rod 34 in the vertical direction. This is done by changing the position and changing the engagement position of the pressing roller 61 with the horizontal portion 35b of the guide surface 35 in the vertical direction to adjust the opening of both links 57 and 58.

On the other hand, as shown in FIG. 1.2, a screw jack 65 (elevating section) is provided at the lower rear side between both mounting frames 1. In this screw jack 65, the lower ends of two links 65b are rotatably supported on a fixed fulcrum 65a, and two other links 65b are rotatably supported on the upper ends of both links 65b via a movable fulcrum 65c. The links 65b are movably supported, and the upper ends of both links 65b are rotatably supported via a movable fulcrum 65d, so that each link 65b constitutes a parallel link mechanism. An operating threaded rod 65e is screwed into one of the two movable fulcrums 65c, and its tip is connected to the other fulcrum 65Cl.

A base plate 66 is fixed on the screw jack 65, and a shaft support 67 is supported on the front side thereof so as to be rotatable in the front and rear direction by a shaft 68, and a second shaft support 69 is connected to the first shaft support 67. 70 so as to be rotatable in the left and right direction. On this second shaft support 69, each of the transfer members 42A,
A diaphragm 71 (with artificial turf pasted on the top surface) is fixed to extend in the front-rear direction below the movement paths of 42B and 42C, and is fixed to the lower surface of the diaphragm 71 behind the second shaft support 69. A rod 72 is inserted through the base plate 66 and urged downward by a spring 73.

An electric motor 74 is installed on the base plate 66, and its output shaft 74a is connected to the diaphragm 74 between the second shaft support 69 and the rod 72.
1 and supported by a bearing 75 on a plywood board 66. Eccentric cam plates 76a and 76b (cam members) are fixed to the left and right sides of the output shaft 74a in a 180-degree symmetrical relationship, so that they can alternately engage with the left and right lower surfaces of the diaphragm 71. . And electric motor 74
Both cam plates 76a are rotated by the rotation of the output shaft 74a.

When 76b rotates, the diaphragm 71 simultaneously reciprocates in the front-rear and left-right directions around the first and second shaft supports 67 and 69. That is, when one cam plate 76a engages with the lower right side surface of the diaphragm 71 as shown in FIG. 2, the rear edge 71a of the image pickup plate 71 tilts upward as shown in FIG. The right edge 71c tilts upward, and the rear edge 71a
The intersection corner between the front edge 71b and the right edge 71C is the highest, and the intersection corner between the front edge 71b and the left edge 71d is the lowest. Next, when the other cam plate 76b engages with the left lower surface of the diaphragm 71, the first
, 2, the front edge 71b of the diaphragm 71 tilts upward, and at the same time its left edge 71d tilts upward, so that the intersection corner between the front edge 71b and the left edge 71d is raised the most. , the corner where the rear edge 71a and the right edge 71c intersect is the lowest. In this way, the diaphragm 71 swings continuously so that its two intersecting corners can alternately assume the uppermost or lowermost positions. This swinging motion can be varied in various ways by changing the position of the cam plate, etc.

Further, in the screw jack 65, the operating screw rod 6
5e is rotated, one of the movable fulcrums 65c screwed thereto moves on the same threaded rod 65e, and both movable fulcrums 65
C move toward or away from each other, and the entire plywood 66 moves up and down. Thereby, the movement of the diaphragm 71 can be adjusted in the vertical direction.

Note that the screw jack 65 and the first and second shaft portions 67.
69 etc. constitute a support section, and the electric motor 74, eccentric cam plates 76a, 76b etc. constitute a drive section.

Next, a description will be given of the effect of supplying the contents to the packaging bag 77 suspended and supported by each of the transfer members 42Δ, 42B, and 42C, and the effect of imparting vibration to the packaging bag A77.

In the state shown in FIGS. 1 to 4, one collar 17 is tilted forward, each feed pawl 12, 13.14 is in the forward movement position, and each stopper plate 24, 25, 26 is moved from above the guide rail 9. They are evacuating. A transfer member 4 is provided in the second stopper recess 22a.
The support shaft 54 of the transfer member 42B is inserted into the third stop 1 to the collar recess 23a, and the support @54 of 2△ is connected to both transfer members 4.
2A and 42B are stopped on the guide rail 9. Below the front chainwheel 2, the transfer member 42C is supported by the main chain 4 and is on its way up. In both transfer members 42A and 42B on the guide rail 9, their support arms 43 and rotation arms 44 are opened to each other, and both clamping plates 46.
The opening 78 of the packaging bag 77 gripped by the handle 48 is also open, and the contents have already been put into the packaging bag 77 from this recess 78.

Further, in the transfer member 42G, both arms 43 and 44 are closed to each other, and the opening 78 of the packaging bag 77 is also closed.

From this state, the transfer member 42C is transferred from the main chain 4 to the guide rail 9-H due to the separation between the support claw 7 and the support bin 56, as shown in FIGS. The transfer members 42A, 42B, and 42C are stopped in a closed state and arranged in sequence on the guide rail 9.

Next, as shown in FIGS. 9 to 11, when the lever 17 tilts backward and each of the feed pawls 12, 13, and 14 moves backward, each of the feed pawls 1
2, 13. Each transfer member 42A, 42B, 42 by 14
The support shafts 54 of C are pushed rearward and enter the first, second and third stopper recesses 2Ia, 22a, 23a, respectively, and the respective transfer members 42A, 42B, 42C move toward the guide rail 9.
Stop while lined up on top of each other. At this time, each stopper plate 24, 25, 26 projects onto the guide rail 9.

In the transfer member 42A, both arms 43, 44 close together and the opening 78 of the packaging bag 77 also closes. In the transfer member 42B, the opening 78 of the packaging bag 77 remains open. In the transfer member 42C, both arms 43, 44 thereof open to each other, opening the opening 78 of the packaging bag 77, and immediately thereafter the packaging bag 77 is opened.
Objects are placed in the container.

During this feeding of the contents, the lever 17 is tilted forward and each feed pawl 12, 13, 14 moves forward, and each topper plate 24, 25, 26 is retracted from the guide rail 9 as shown in FIG. 12.13. In addition, the transfer member 42A has the support claw 7 and the support pin 5.
Main chain 4 is removed from guide rail 9 by engagement with 6.
and rises above the rear chain wheel 3.

Along with this ascent, another transfer member (not shown) is in the process of being ascended below the front chain wheel 2, resulting in the same state as in FIG. 1. Thereafter, the supply of the contents is repeated under the same action.

On the other hand, the diaphragm 71 continues to vibrate and strikes the bottom of the storage portion 79 of the packaging bag 77 to which the stored items have been supplied from below. Therefore, the contents are reliably packed into the packaging bag 77. In particular, the diaphragm 71 not only vibrates the bottom of the housing portion 79 in the vertical direction from directly below it, but also can provide imaging from both the left and right sides of the bottom, as well as from both the front and rear sides. Due to the combination of the various vibrations (turbulence), the contents of the packaging bag 77 become even tighter.

Effects of the Invention In short, according to the present invention, the packaging bag 77 is
Since the vibration is applied to the storage part 79 of the packaging bag 77, the contents are reliably packed into the packaging bag 77, and the storage part 79 of the packaging bag 77 is not loosened after binding, so that a good packaging state can be obtained.
