The roller assembly 5, the sealing cut portion SCP, the chute 11, the gate assembly GA, the peeling supporter 13 and the load cell 10 are supported by the main frame 2. The roller assembly 5, the sealing cut portion SCP, the chute 11, the gate assembly GA, the filling supporter 13 and the load cell 10 are arranged in this order from the input end to the output end of the main frame 2 . The roller assembly 5 includes a bobbin roll 5A, a tension roll 5B, a guide roll 5D, feeding rolls 5C and 5F, and an eye mark sensor 5E. The control panel 6 controls the operation of the automatic metering vesicle organ of the present invention. The control panel 6 is mounted to the main frame 2 through fixing means such as a bracket. The present invention can be referred to as an automated weighing tube roll compact.

The bobbin roll 5A is supported on the main frame 2 by a bracket. A bobbin roll 5A is disposed at a feeding end of the main frame 2 for feeding the wrapping back film 3. At this time, the wrapping back film 3 is in the form of a tube, and such wrapping pack film is wound around the bobbin roll 5A.

The tension roll 5B is rotatably mounted on a pair of tension rolls 5B provided on both left and right sides of a bracket supporting the bobbin roll 5A. Both ends of the spring are connected to the link of the bracket and the tension roll 5B. Therefore, when the wrapping back film 3 fed from the bobbin roll 5A passes through the outer circumferential surface of the tension roll 5B, tension suitable for the wrapping bag to which the tension roll 5B is fed by the elasticity of the spring, .

The feeding roll 5C is provided on the main frame 2. A drive roll 5C is disposed between the bobbin roll 5A disposed at the input end of the main frame 2 and the discharge end of the main frame 2. [ At this time, the feeding rolls 5C and 5F include the driving roll 5C and the driven roll 5F.

The feeding rolls 5C and 5F are rotatably mounted on a support such as a bracket fixed to the main frame 2. [

The driven roll 5F is rotatably installed on the support. At this time, the supporting body is provided with a long hole extending in the longitudinal direction (i.e., in the direction of the discharge end from the input end of the main frame 2), and the elongated hole is provided with a slide member and a driven adjustment member facing the slide member do. Further, the threaded portion of the outer circumferential surface of the feeding adjusting member is engaged with the screw hole of the supporting member so that the driven adjusting member can be moved forward or backward in the direction of the sliding member. The driven adjusting member may be screwed in one direction to advance to be close to the slide member and the driven adjusting member may be screwed in the other direction to be retracted away from the slide member. A spring is interposed between the slide member and the driven adjustment member. A roll shaft provided at both ends of the driven roll 5F is rotatably coupled to the slide member. Therefore, the driven roll 5F is configured to be able to move forward and backward in the driving roll 5C, and normally, the outer peripheral surface of the driven roll 5F is in contact with the outer peripheral surface of the driving roll 5C.

The drive roll 5C is connected to a motor shaft of a motor (not shown) by power transmission means (e.g., coupling, gear, etc.), and when the motor shaft of the motor rotates, the drive roll 5C rotates When the drive roll 5C is rotated, the driven roll 5F having its outer circumferential surface abutted against the outer circumferential surface of the drive roll 5C rotates. The drive roll 5C and the driven roll 5F are rotated in the direction of feeding (feeding) the package back film 3 downward (for example, the drive roll 5C is clockwise, the driven roll 5F is half Clockwise).

Therefore, the wrapping back film 3 passes between the drive roll 5C and the movable driven roll 5F and is fed downward. At this time, the driven roll 5F is configured to be able to move back and forth in the drive roll 5C, and normally, the outer peripheral surface of the movable driven roll 5F is in contact with the outer peripheral surface of the drive roll 5C. At this time, the spring pushes the slide member in the direction of the drive roll 5C so that the outer peripheral surface of the driven roll 5F is brought into contact with the outer peripheral surface of the drive roll 5C at an appropriate pressure (elastic force) The elastic force of the spring can be adjusted by adjusting the length of the driving roll 5C and the driven roll 5C so that the pressure applied to the outer circumferential surface of the driven roll 5F can be adjusted to the outer circumferential surface of the driving roll 5C, It is possible to adjust the conditions such as the frictional force and the speed of feeding the wrapping back film 3 by the opposite direction rotation of the wrapping film 5F. That is, the ability to adjust the pressure at which the outer circumferential surface of the driven roll 5F is in contact with the outer circumferential surface of the drive roll 5C makes it possible to smoothly supply the wrapping back film 3 to the package back forming section 12 it means. Particularly, since the spring is interposed between the slide member and the feeding control member, a force of retreating the drive roll 5C from the driven roll 5F acts on the wrapping back film 3 while the wrapping back film 3 is fed, 5C, the spring is compressed so that the driven roll 5F mounted on the slide member is instantly widened smoothly on the outer peripheral surface of the drive roll 5C, So that it can be supplied to the next package back forming section 12 more smoothly.

At least one guide roll 5D is disposed between the feeding rolls 5C and 5F and the tension roll 5B. The guide roll 5D is rotatably disposed on the main frame 2. [ The wrapping back film 3 unwound from the bobbin roll 5A is fed to the feeding rolls 5C and 5F via the guide roll 5D. In the main frame 2, the feeding stand is arranged in the horizontal direction, and the guide roll 5D guides the wrapping back film 3 to be fed onto the feeding stand.

On the other hand, an eye mark set 5E is provided on the path through which the packaging back film 3 passes. The eye mark set 5E includes a sensor such as an optical sensor and detects the eye mark displayed on the packaging back film 3 so that the packaging back film 3 passes through the feeding roll 5C one pitch at a time, (12). The sensor of the eye mark set 5E is connected to the control unit provided on the control panel so that the sensor senses the eye mark of the wrapping back film 3 and transmits it to the control unit, So that the film 3 is fed to the forming section 12 so as to be fed by one pitch. At least the motor shaft of the motor is connected to the center of the driving roll 5C constituting the feeding roll 5C. The controller is electrically connected between the motor and the sensor, and receives the detection signal of the eye mark sensed by the sensor The motor with the motor shaft connected to the driving roll 5C is intermittently rotated at intervals of one pitch so that the wrapping back film 3 passes the feeding roll 5C through the forming portion 12 Direction) by one pitch.

The packaging back film 3 is laid down in the horizontal direction on the feeding stand on which the eye mark set 5E is placed and the packaging back film 3 that has passed through the feeding roll 5C is conveyed in a standing state under the feeding roll 5C In other words, to the forming section 12.

The sealing cut portion SCP seals the lower end portion of the wrapping back film 3 supplied through the roller assembly 5 and cuts the upper end portion. The wrapping back film 3 supplied through the feeding roll 5C constituting the roller assembly 5 is formed by sealing the tube-shaped film 3 in the package back-forming portion 12 (hot sealing by melting by heat) Thereby forming a packing bag having an inlet at the upper end thereof. A packaging back-forming section 12 is disposed in the main frame 2 under the feeding roll 5C.

In the present invention, the packaged back forming section 12 includes a lower sealing bar 12AL and a cutting knife CK.

The lower sealing bar 12AL includes a lower fixed sealing bar fixed to the main frame 2 and a lower movable sealing bar which moves back and forth at a position facing the fixed sealing bar by the bar moving means. The lower sealing bar 12AL is disposed in a direction (orthogonal direction) intersecting with the conveying direction of the wrapping back film 3. If the direction in which the wrapping back film 3 is transported from the feeding end of the main frame 2 to the discharge end direction is referred to as the longitudinal direction, the lower sealing bar 12AL can be moved in the left and right width direction . The lower fixed sealing bar is provided with an impulse sealing heating wire so that the film is sealed by the heat of the heating wire. The bar moving means may be a cylinder to which a cylinder rod is connected to a lower movable sealing bar. Of course, in addition to the cylinder, there is a motor, a linear guider which is drive-connected between the motor shaft of the motor and the lower movable sealing bar, and which moves the movable sealing bar downward by rotation of the motor shaft to move back and forth at a position facing the fixed sealing bar . It is a matter of course that all the means for moving the lower movable sealing bar in the direction opposite to the lower fixed sealing bar can be employed as the bar moving means.

Therefore, the lower end of the packaging bag film 3 which is erected through the feeding roll 5C and is supplied is sealed (hot bonded) by the lower sealing bar 12AL, and the lower end of the lower sealing film A sealing portion is formed at a lower end portion of the package back film 3 because the lower sealing portion is spaced apart from the lower fixed sealing bar and is hot sealed by the heat of the impulse sealing wire of the lower sealing bar 12AL, An open packaging bag is formed. At this time, the packaging bag is in a state of continuing to another packaging bag film 3 on which the lower sealing portion is not yet formed.

The packaging bag in which the lower end portion is sealed via the packaging back-forming portion 12, that is, the lower sealing bar 12AL, is unified (individualized) in the packaging bag by the cutting portion CP. A state in which the packaging bag having the sealing portion formed at the lower end thereof is connected to the other packaging bag film 3 on which the lower sealing portion is not yet formed may be referred to as a packaging bag. The cut portion CP may be formed in the packaging bag, (That is, an end portion opposite to the lower end sealing portion of the packaging bag) is cut, the packaging bag having the lower end sealing portion and the sealing portion formed on at least one end portion is separated into one sheet.

The cutter blade having the above-described configuration is disposed in a direction (orthogonal direction) intersecting with the conveying direction of the packaging bag. If the direction in which the packaging bag is transported from the input end of the main frame 2 to the discharge end direction is referred to as the longitudinal direction, the cutter blade is arranged in the left and right width direction orthogonal to the longitudinal direction of the main frame 2. The cutter blade moving means may be a cylinder having a cylinder rod connected to the movable cutter blade CP2. Of course, in addition to the cylinder, the motor is driven and connected between the motor shaft of the motor and the movable cutter blade CP2 so that the movable cutter blade CP2 is moved forward and backward at the position facing the fixed cutter blade CP1 by the rotation of the motor shaft And a linear guider for driving the motor. It is a matter of course that all the means for moving the movable cutter blade CP2 forward and backward in the direction opposite to the fixed cutter blade CP1 can be employed as the cutter blade moving means.

The cutting portion CP may include the fixed cutter blade CP1 and the movable cutter blade CP2 and may be the cylinder or the like as the cutter driving portion .

The packaging bagilla enters between the movable cutter blade CP2 and the fixed cutter blade CP1 and stops when the movable cutter blade CP2 is spaced apart from the fixed cutter blade CP1. As described above, since the wrapping back film 3 advances by one pitch, the packaging bag is also advanced by a pitch, so that the packaging bag is stopped between the movable cutter blade CP2 and the fixed cutter blade. Next, the movable cutter blade CP2 is advanced to the fixed cutter blade CP1 to cut the upper end of the packaging bag from the packaging bag by the movable cutter blade CP2 and the fixed cutter blade CP1 A packing bag having a lower end and a sealing portion formed on at least one end thereof may be unified into a single piece by cutting an end portion opposite to the end portion where the sealing portion is formed. On the other hand, the cutting portion CP may be constituted by a pair of movable cutter blades that face each other, and the pair of movable cutter blades may be moved forward and backward to form a single wrapping bag. In this case, when the side sealing portion is formed at both ends of the packaging bag 15, when the packaging bag 15 is cut (unified) from the packaging bag 15, the packaging bag 15 has the lower sealing portion and both side ends And an upper end portion may have an envelope shape having an inlet. On the other hand, since one end of each of the left and right side end portions of the package bag film 3 is continuous, if the sealing portion is formed only at the other end portion of the packaging bag, A bottom sealing portion may be provided at the lower end of the packaging bag, and an envelope-shaped packaging bag may be formed with an inlet at an upper end of the packaging bag. At this time, in the present invention, when the lower sealing part of the packing bag is formed, the lower sealing part of the lower sealing bar 12AL functions to grip the packing bag when the power of the heater is cut off and then cooled again.
