Description

The present invention relates to a bag package reversal device immediately reversing the applied bag package manufactured in the vertical bag filling and packaging machine under the vertical bag filling and packaging machine for producing a bag package.

Conventionally, in a general vertical bag making and filling machine as shown in FIG. 8, a belt-like packaging material Fw fed in a downstream direction by a pair of paper feed belts 26 a and 26 b is made by a bag making machine 6. The cylindrical packaging material is formed by wrapping from the rear side of the cylinder 22 to bend and forming the longitudinal seal 4 by sticking both ends in the width direction of the belt-shaped packaging material Fw on the front side of the bag-filling cylinder 22 with the vertical sealers 28a and 28b. Formed into Ft, the packaged product is put into the bag making and filling cylinder 22 and filled into the tubular packaging material Ft, and is further tubular by the horizontal sealers 24a and 24b that operate in the longitudinal direction of the vertical bag making and filling packaging machine. The bag package 7 is manufactured by applying the horizontal seal 3 in the direction crossing the packaging material Ft and cutting it in the middle of the horizontal seal 3. The manufactured bag package 7 is guided by a guide chute 27, transferred to a transport device 30 such as a belt conveyor, and further transported to a downstream portion where an inspection device and a boxing device are disposed. In this case, the bag packaging body 7 is discharged from the vertical bag making and packaging machine with the surface to which the vertical seal 4 is applied facing upward, and is conveyed downstream.

When the bag packaging body 7 manufactured by the vertical bag making filling and packaging machine is packed in a box, it is usually packed in the box with the vertical seal surface of the bag packaging body facing down. For this reason, a reversing device using an air cylinder as a drive source may be provided at the discharge portion of the vertical bag making filling and packaging machine (Patent Document 1). An example of the reversing device using the air cylinder as a drive source as described above is shown in FIG. 9A is a schematic view of the reversing device as viewed from the front, FIG. 9B is a schematic view of the reversing device as viewed from the side, and shows its configuration. FIGS. 9C to 9E are horizontal views. The operation is shown in the schematic diagram seen from FIG.

As shown in FIG. 9 (a), FIG. 9 (b), the reversing device includes a guide chute 27,突押and cylinder 35 for driving it between the plate 31 and突押on the back side thereof, and a stopper plate 32 it A stopper cylinder 36 for driving is provided. The guide chute 27 is formed with a pushing opening 33 through which the pushing plate 31 can pass and a stopper opening 34 through which the stopper plate 32 can pass. The pushing cylinder 35 and the stopper cylinder 36 are attached to a lower base (not shown) of the vertical bag making filling and packaging machine.

The operation of the reversing device is composed of the following three movements. As shown in FIG. 9 (c), the first operation is to detect the fall of the bag package 7 and to operate the stopper cylinder 36 to advance the stopper plate 32 through the stopper opening 34. The operation is to receive the falling bag packaging body 7. As shown in FIG. 9 (d), the next operation is to move the push-push plate 31 forward through the push-push opening 33 by operating the push-push cylinder 35 and push the bag package 7 forward. Drop to fall down. By this operation, the bag package 7 is discharged with the vertical seal as the bottom surface. Finally, as shown in FIG. 9 (e), the operation of the stopper cylinder 36 and the pushing cylinder 35 is released, and the stopper plate 32 and the pushing plate 31 are moved backward to the rear of the guide chute 27 . .

As described above, since this reversing device uses the reciprocating motion obtained by applying or releasing the air pressure to the air cylinder as it is, the structure and operation are simple, but because of the reciprocating motion, FIG. The return operation time shown in e) is a useless time that does not contribute to the operation of inverting the bag. If the bag falls during the return operation of the thrust plate 31 and the stopper plate 32 , the reversing operation may not be performed or an incomplete operation may occur. For this reason, in this reversing device, there is a limit to the reversing capacity of the bag packaging body, and there is a problem that the vertical bag making filling packaging machine cannot cope with high speed operation .

  With reference to the drawings, an embodiment of a bag packaging body reversing apparatus using a turret of a vertical bag making filling and packaging machine according to the present invention will be described. FIG. 1 shows a schematic diagram of a bag package reversing device using a turret of a vertical bag making filling and packaging machine. The turret 40 includes four storage pockets 42a to 42d (generically denoted by reference numeral 42) that are divided in the circumferential direction by partition plates 46a to 46d around a shaft 52 that is a rotatable rotating shaft. The turret 40 is driven by a motor 41 capable of speed control. Hereinafter, with reference to FIGS. 2-5, the installation position and structure of a bag packaging body inversion apparatus, and operation | movement are demonstrated.

First, the installation position and operation of the bag packaging body reversing device (hereinafter abbreviated as “reversing device” for simplicity) will be described. As shown in FIGS. 2 and 3, the inverting apparatus, a vertical bag filling and packaging machine of the transverse sealer 24a, is installed immediately below the 24b, the transverse sealer 24a, and 24b as viewed in the front rotated toward the body A turret 40 is provided. In the state shown in the drawing, among the plurality of storage pockets 42 provided in the turret 40, one storage pocket 42a stands by at a position where the falling bag packaging body 7 can be received and stored. This standby position is a receiving position where the storage pocket 42 can receive and store the bag package 7 manufactured by the vertical bag making filling and packaging machine.

The position where the turret 40 stands by is determined by the stop position detection sensor 44 detecting the detection portion of the stop position detection plate 43 indicating the position of the storage pocket 42 and grasping the control unit of the reversing device. The stop position detection plate 43 is attached to one end of the shaft 52 and rotates together with the shaft 52. Further, as shown in the right side view of FIG. 1 and FIGS. 3 and 4, the stop position detection plate 43 has the same number of storage pockets 42 as the storage pockets 42a to 42d. Cuts 43a to 43d are formed as detection portions. The stop position detection sensor 44 is fixedly provided on the apparatus base in the vicinity of the stop position detection plate 43, and optically or magnetically detects the detection portion of the stop position detection plate 43. A product detection sensor 45 is disposed in the vicinity of the turret 40 and detects that the bag package 7 has fallen into the storage pocket 42. As shown in FIGS. 1 to 4, the product detection sensor 45 is provided at a position facing the storage pocket 42 waiting at the receiving position of the turret 40 obliquely from above and from the side.

When the product detection sensor 45 confirms that the vertical bag making filling and packaging machine has started operation and the bag packaging body 7 has fallen into the storage pocket 42a waiting at the receiving position , the control unit rotates the motor 41. Then, the turret 40 starts to rotate in the direction of the discharge device 30. When the turret 40 is rotated, the stop position detection plate 43 is also rotated and the detection portion (the cut 43 ) is also moved. Therefore, the stop position detection sensor 44 is lost once. When the next storage pocket 42d comes to a position where the falling bag packaging 7 can be stored, the next detection portion (the cut 43) of the stop position detection plate 43 also moves to a detection position where the stop position detection sensor 44 can detect. Therefore, the position detection sensor 44 detects the detection portion and outputs it again. At this timing, the control unit stops the rotation of the motor 41. As a result, the turret 40 rotates intermittently. Since the partition plate 46a constituting the storage pocket 42a is inclined, the bag wrapping body 7 stored in the storage pocket 42a slides downward with the vertical seal on the lower surface and transfers to the carry-out device 30. . That is, with the rotation of the turret 40, in the illustrated example, the position where the storage pocket 42a shown in FIG. It becomes the discharge position to discharge to. Thereafter, with the intermittent rotation of the turret 40, the storage pocket 42 is stopped at the receiving position and the discharge position sequentially every time the turret 40 is stopped. At the receiving position, the bag packaging manufactured by the vertical bag making and filling packaging machine The body 7 is received, and at the discharge position, the operation is repeated in which the bag packaging body 7 that has been inverted to the state in which the vertical seal 4 is on the lower side by the rotation of the turret 40 is discharged to the front of the vertical bag making filling packaging machine.

The turret 40 has a shaft 52 which is a rotating shaft thereof parallel to the longitudinal direction of the horizontal sealers 24a and 24b. Arranged to have an extending axis. The turret 40 rotates from top to bottom on the front side due to the rotation of the shaft 52, that is, in the direction in which the longitudinal seal 4 side of the bag package 7 received at the receiving position faces. Below, the detailed structure of the turret 40, the connection with the motor 41 capable of speed control, and the assembly order will be described.

  As shown in FIG. 4, both end portions of the shaft 52 pass through both end plates 49a, 49b, respectively, and four partition plates 46a, 46b, 46c, 46d are connected to both end plates 49a, 49b. The assembly of the turret 40 is completed by fixing 49b to the shaft 52. Accordingly, the storage pocket 42a is between the partition plates 46a and 46d, the storage pocket 42b is between the partition plates 46a and 46b, the storage pocket 42c is between the partition plates 46b and 46c, and the partition plates 46c and 46d are between the partition plates 46c and 46d. Storage pockets 42d are respectively formed.

  Both ends of the shaft 52 of the turret 40 are passed through the reversing device mounting brackets 50a and 50b, and are fixed so as not to prevent the rotation of the shaft 52 via ball bearings (not shown). Next, the driving pulley 47a is fixed to one end of the shaft 52, the stop position detection plate 43 is passed through the opposite end, and the detection portion is adjusted to a position that matches the position of the partition plate. The stop position detecting plate 43 is fixed to the shaft 52. In this state, the turret 40 is attached to a position directly below the horizontal sealers 24a and 24b on the lower base of the vertical bag making filling and packaging machine.

  As shown in FIG. 5, after the speed-controllable motor 41 is mounted on the reversing device drive motor mounting bracket 51, the pulley 47 b is fixed to the rotating shaft of the motor 41. In this state, after connecting the driving pulley 47a attached to the turret 40 and the pulley 47b attached to the motor 41 on the lower base of the vertical bag making filling and packaging machine with the driving belt 48, the reversing device The drive motor mounting bracket 51 is fixed. Finally, the stop position detection sensor 44 and the product detection sensor 45 are attached to adjust the position, and the motor and sensor are electrically wired. Thereby, the reversing device is completed.

In this embodiment, a DC brushless motor is used as a motor capable of driving speed control, a dedicated programmable logic controller (PLC) is mounted for control, and control signals and status signals are mutually transmitted with the vertical bag filling and packaging machine. It is only to exchange. The operating speed is set manually by connecting a speed command variable resistor (speed volume) to the motor drive amplifier. From PLC, start, stop, only the rotation direction of the signal is sent as a command, an abnormal operation of the motor 41, including a turret Ru sent to the PLC as an alarm signal. The motor rotation direction signal is the rotation direction from the top to the bottom of the turret 40 on the front side, that is, the rotation direction in the direction in which the vertical seal side of the bag packaging body stored in the storage pocket faces. It is a signal determined correspondingly.

  The PLC sends a start command to the motor drive amplifier when the detection signal from the product detection sensor 45 is input while the vertical bag filling and packaging machine is in operation, and the stop position detection sensor 44 while the DC brushless motor is rotating. Sends a stop command to the motor drive amplifier in response to the input of the signal for detecting the detection portion of the stop position detection plate 43. In addition, a return-to-origin operation is required to move to a position where the bag packaging body 7 in which the storage pocket of the turret 40 falls once after the power is turned on can be stored. It is assumed that the time when the origin return operation is performed is grasped by the status signal of the packaging machine and performed at the same time.
