As shown in FIG. 2, for convenience of explanation, the moving direction of the packaging film sent from the film supply mechanism to the former 16 is referred to as the front F direction of the bag making, filling and packaging machine 8, and the opposite direction is referred to as the rear B direction. , the width direction of the packaging film will be explained as the width W1 direction of the bag making, filling and packaging machine 8.
The frame 14 includes a bottom frame 1402, side plates 1404 that stand up from the bottom frame 1402 and cover the left and right sides of the device main body 12, and a top plate 1406 that covers the top of the device main body 12.
The filling cylinder 18 includes a filling cylinder main body 28 disposed vertically penetrating the center of the former 16 and a hopper 2802 provided at the top of the filling cylinder main body 28, and the hopper 2802 projects above the top plate 1406. There is.
Above this hopper 2802, a product loading hopper 6002 of the weighing machine 6 is arranged.

The former 16 folds a band-shaped packaging film having a width and length supplied by the film supply mechanism onto the outer circumferential surface of the filling cylinder main body 28 into a cylindrical shape.
The film feeding mechanism 20 includes a pair of belt/pulley mechanisms 2002, and the former 16 intermittently feeds the packaging film folded into a cylindrical shape downward, and the vertical sealing device 22 feeds the packaging film folded into a cylindrical shape. A cylindrical film F is obtained by sealing both ends in the width direction.
The lateral sealing device 24 seals and cuts the lower portion of the cylindrical film F in the length direction.
In detail, at the first position of the cylindrical film F, the lower part of the cylindrical film F in the longitudinal direction is sealed by the horizontal sealing device 24, and the weighed product is filled from the product input hopper 6002 via the hopper 2008. The tube body 28 is inserted into the cylindrical film F whose lower portion is sealed.
Thereafter, the film transport mechanism 20 transports the cylindrical film F from the first position to a second position below the first position.
At the second position, the upper part of the cylindrical film F into which the product has been introduced is sealed by the horizontal sealing device 24 to form the bag body 10 in which the product is enclosed, and at the same time, the tube located at the first position above The lower part of the cylindrical film F is sealed, and at the same time, the bag 10 containing the product is separated from the cylindrical film F located at the first position.

In this embodiment, as shown in FIGS. 2 and 3, the present invention is applied to a mounting structure of a drive source 30 that linearly moves a pair of seal portions 24A and 24B of a horizontal sealing device 24 in a reciprocating direction in a direction toward and away from each other. has been done.
As shown in FIG. 4, the drive source 30 includes a servo motor 30A and a reducer 30B integrated with the servo motor 30A, and a rectangular flange 30C is provided at the boundary between the servo motor 30A and the reducer 30B. It is being
Then, as shown in FIGS. 3(B) and 3(C), the toggle link mechanism 32 is actuated by the output shaft 3002 of the reducer 30B, and the pair of seal portions 24A, 24B are reciprocated and linearly moved.
The pair of seal portions 24A, 24B include a pair of seal blocks 34A, 34B for sandwiching and sealing the cylindrical film F from both sides in the front and rear directions, and a bar-shaped sealer supported by the seal blocks 34A, 34B, respectively. Although not shown, one sealer 36A is provided with a cutter for cutting the packaging film F in its width direction, and the other sealer 36B is provided with a cutter insertion groove.
Note that in FIG. 3(B), the symbol P indicates a product enclosed in the bag body 10.

Because the toggle link mechanism 32 operates to cause the other seal part 24B, which includes a seal block 34B and a sealer 36B, to move in response to the movement of one seal part 24A, which includes a seal block 34A and a sealer 36A, the lateral seal device 24 is provided with a reaction block 38A to which the toggle link mechanism 32 is connected, and connection rods 38B, 38B that connect the reaction block 38A to the seal block 34B. The connecting rods 38B, 38B are attached to the reaction block 38A and the seal block 34B, pass through the seal block 34A, and guide the movement of the seal block 34A.

The sealers 36A and 36B, which are arranged in front and behind the cylindrical film F, are moved in the opening and closing direction by the operation of the toggle link mechanism 32, which will be described in detail later. The cylindrical film F is brought into contact with the cylindrical film F, and a seal such as a heat seal is applied to the cylindrical film F at the time of contact. The servo motor 30A serves as a drive source 30 for opening and closing the seals 24A and 24B, and is disposed at a position downwardly away from the opening and closing operation surfaces of the seals 24A and 24B. The servo motor 30A is preferably a pulse motor with excellent controllability and responsiveness, but is not limited thereto.

The toggle link mechanism 32 is configured as a double toggle link mechanism in which a first toggle link mechanism 32A and a second toggle link mechanism 32B are combined. The first toggle link mechanism 32A and the second toggle link mechanism 32B are arranged in a manner to perform a toggle link operation in a plane MM (FIG. 3(A)) perpendicular to the bar-shaped extending direction of the sealers 36A and 36B. There is. Due to this arrangement, the layout and operation of the toggle link mechanism 32 are not restricted by the servo motor 30A and the seals 24A and 24B, compared to a case where the toggle link mechanism 32 is arranged in a manner that it toggles in a horizontal plane. This increases the degree of freedom in layout design, and enables efficient toggle operation in terms of force transmission and boosting.

The first toggle link mechanism 32A is disposed between one seal portion 24A and a reaction block 38A that is disposed apart from the seal portion 24A in the opening direction. The first toggle link mechanism 32A has one first link body 42A rotatably connected to one seal portion 24A by a shaft 40A at one end, and rotatably connected to the reaction block 38A by a shaft 40B at one end. The other first link body 42B is connected to the other first link body 42B, and the intermediate link body 46 is rotatably connected to the other ends of the first link bodies 42A and 14 by first intermediate connection shafts 44A and 44B, respectively. We are prepared. The intermediate link body 46 is rotatably arranged around a fixed machine frame by its central shaft 48, and since the position of its axis of rotation is fixed with respect to the machine frame, it is a toggle link mechanism that operates stably. It can be done.

The second toggle link mechanism 32B includes two second link bodies 50A and 50B. One second link body 50A is attached to the output shaft 3002 of the servo motor 30A at one end, and the other second link body 50B is rotatable with respect to the first intermediate connecting shaft 44A of the first toggle link mechanism 32A. is connected to. The second link bodies 50A, 50B are rotatably connected to each other by a second intermediate connecting shaft 52 at their other ends. Note that the other second link body 50B may be rotatably connected to the other first intermediate connecting shaft 44B of the first toggle link mechanism 32A instead of the first intermediate connecting shaft 44A.

The first toggle link mechanism 32A and the second toggle link mechanism 32B perform a link operation so as to be bent by the first intermediate connecting shafts 44A, 44B and the second intermediate connecting shaft 52, respectively. When the second toggle link mechanism 32B moves toward a straight line, the first toggle link mechanism 32A pushed by the second link body 50B of the second toggle link mechanism 32B also moves toward a straight line. .

In the bag making, filling and packaging machine 1A, the output of the servo motor 30A as the drive source 30 is converted by the toggle link mechanism 32 into an opening/closing operation of the seal parts 24A, 24B, and the seal parts 24A, 24B open and close the cylinder by this conversion of operation. The cylindrical film F is opened and closed by sandwiching the cylindrical film F, and during the closing operation, the cylindrical film F is sealed, for example, by heat sealing. In the second toggle link mechanism 32B, one second link body 50A rotates together with the output shaft 3002 of the servo motor 30A, and the angle at which the two second link bodies 50A and 50B intersect at the second intermediate connecting shaft 52 is When performing a linear movement that approaches 180 degrees, the force pushing the first intermediate connecting shaft 44A against the first toggle link mechanism 32A increases. At this time, due to the related structure relationship between the first toggle link mechanism 32A and the second toggle link mechanism 32B, the two first link bodies 42A, 14 and the intermediate link body 46 are connected to the first toggle link mechanism 32A as well. The first intermediate connecting shafts 44A and 44B move toward a straight line so that the intersecting angles are close to 180 degrees.

Due to this operation of the first toggle link mechanism 32A, one first link body 42A directly brings one sealer 36A close to the cylindrical film F, and the other first link body 42B moves the reaction block 38A to the cylindrical film F. Make a pushing motion in the direction away from F. The action of pushing the reaction block 38A causes the other sealer 36B to approach the cylindrical film F from the side opposite to the one sealer 36A via the connecting rods 38B, 38B. Therefore, as the second toggle link mechanism 32B moves closer to a straight line, the first toggle link mechanism 32A is pushed by an increased force from the first intermediate connecting shaft 44A, and at the same time the first toggle link mechanism moves closer to a straight line. 32A, both sealers 36A and 36B abut against the cylindrical film F at the seal portions 24A and 24B with further increased force. As a result, both sealers 36A and 36B can horizontally seal the cylindrical film F with high sealing pressure.

Next, the mounting structure of the drive source 30 of the present invention will be explained.
As shown in FIG. 2, a pair of brackets 56 are provided, one end of which is supported in a height-adjustable manner by the support column 54, and the other end supported by the side plate 1404 of the frame 14 in a height-adjustable manner. The connecting rod 38B is supported by each bracket 56 via a slide bearing 56A so as to be capable of reciprocating linear movement in the front F direction and the rear B direction.

Once all the bolts B0, B1, and B2 are screwed into the female screws S0, S1, and S2 in this way, tighten the entire bolts B0, B1, and B2 by rotating them little by little, and the work of installing the drive source 30 is completed. finish.
Therefore, the drive source 30, which is disposed in a narrow space in the rear B direction of the bag-filling-sealing machine 8 with respect to the vertical conveyance path of the cylindrical film F, can be attached by one worker.

According to this embodiment, one worker can suspend the drive source 30 in a movable state along the bolt insertion groove 62. Move the drive source 30 or the drive source side attachment member 64 so that the shaft portion of S0 is located deep in the bolt insertion groove 62, and then fasten the bolts B0, B1, and B2 to the female threads S0, S1, and S2. The drive source 30 can be attached to the frame-side attachment member 60 by performing the work.
Therefore, the drive source 30 can be attached to the frame side attachment member 60 by one person without requiring two workers, one who supports the drive source 30 and the other who rotates the bolt, as in the past. It becomes possible.
In particular, in the past, the drive source 30 was placed in a narrow space in the rear B direction of the bag-filling-sealing machine 8 with respect to the upper and lower transport path of the cylindrical film F, and two people were required to attach the drive source 30 in this narrow space. However, in the present embodiment, it can be easily installed by one worker in a narrow space, which improves the work efficiency of installing the drive source 30. It will be advantageous.

In addition, in the embodiment, a case has been described in which the frame side first lateral attachment plate part 6002 to which the drive source 30 is attached extends in the horizontal direction, but the frame side first lateral attachment plate part 6002 extends from the base part 6002A. If the tip portion 6002B has an inclination that is located at a slightly higher location, the driving source 30 can be stably suspended from the first horizontal mounting plate portion 6002 on the frame side by the bolt B0. It becomes more advantageous.
However, even if the frame side first horizontal mounting plate part 6002 has an inclination such that the tip part 6002B is located slightly lower than the base part 6002A, the drive source 30 does not slip down along the bolt insertion groove 62, and the bolt It is only necessary to obtain a state in which the drive source 30 is suspended from the frame-side first horizontal attachment plate portion 6002 by B0.
In short, it is sufficient that the frame-side first horizontal attachment plate portion 6002 extends substantially horizontally.
Further, the drive source 30 may be attached to the frame side first horizontal mounting plate portion 6002 by one bolt B0 that is inserted into the bolt insertion groove 62 and screwed into the female thread S0. It is advantageous to attach the drive source 30 to the frame-side first horizontal mounting plate portion 6002 using the bolts B1 and B2 in order to attach the drive source 30 in a more stable state.
In addition, a plurality of bolt insertion grooves 62 are provided in the first horizontal mounting plate portion 6002 on the frame side at intervals in a direction perpendicular to the direction in which the bolt insertion grooves 62 extend, and the drive shaft 62 is aligned with the deep part of the bolt insertion grooves 62. By providing a plurality of female threads S0 on the source side upper mounting surface 6412 and providing a plurality of bolts B0 that are inserted into the plurality of bolt insertion grooves 62 and screwed into the female threads S0, the drive source 30 is attached to the frame side first horizontal mounting plate portion 6002. This is more advantageous in that the suspended state can be stably obtained.
Furthermore, in this embodiment, a case has been described in which the female thread S0 is provided at a location on the drive source side upper mounting surface 6412 that matches the deep part of the bolt insertion groove 62, but the bolt B0 connects the drive source 30 Since it is sufficient to obtain a state in which the source-side mounting member 64 is suspended from the frame-side first horizontal mounting plate portion 6002, the location where the female thread S0 is provided is not limited to the deep part of the bolt insertion groove 62. It may be located in the middle of the bolt insertion groove 62 in the extending direction or in the bolt insertion groove 62 near the open end. However, if a female thread S0 is provided at a location on the drive source side upper mounting surface 6412 that matches the deep part of the bolt insertion groove 62, the drive source 30 and the drive source side mounting member 64 are attached to the frame side first horizontally by the bolt B0. This is advantageous in stabilizing the suspended state from the plate portion 6002.
