In the embodiment, the positioning extension 10a rising outside the lower opening member 82b by the expansion of the bag opening 10e by the bag opening means 22 is held by the lower opening member 82b and the pressing member 88. (See FIG. 5). Further, the bag holding means 26 holds both the pressing members 88 and 88 away from the bread feeding path so as to hold the bag 10 in accordance with the time when the bread 18 fed by the pushing conveyor 28 reaches the bottom of the bag 10. It is configured to release.

  A sealing portion is provided on the downstream side from the filling position S4 to seal the vicinity of the bag mouth portion of the bag 10 filled with bread with a knotting tool or heat welding.

  Next, the operation of the bagging machine of the embodiment will be described. Positioning and extension of the uppermost bag 10 stacked and mounted on the bag mounting table 30 by lowering the moving body 36 of the bag take-out means 14 positioned above the bag mounting table 30 of the bag stacking unit 12. The portion 10a is sucked and held by the two suction cups 38a and 38a, and the single bag 10 is taken out from the bag stacking portion 12 by moving the moving body 36 upward and horizontally. By lowering the moving body 36 moved to the upper position with respect to the bag conveying means 20 and releasing the suction action by the suction cups 38a, 38a, the bag 10 held by suction by the suction cups 38a, 38a is positioned and extended. The exit side is placed on the suction conveyor 40, and the bag bottom side is placed on the bag transport table 42 and delivered to the receiving position S1 of the bag transport means 20 (see FIG. 1). At this time, if the first suction port 46a of the suction belt 46 has arrived at the receiving position S1, the suction acting on the first suction port 46a communicating with the first long hole 54a of the first suction chamber 48 is performed. The bag 10 is reliably sucked and held on the bag transport surface of the suction belt 46 by the force. In this state, the second long hole 54 b of the first suction chamber 48 is closed by the suction belt 46.

  When the suction belt 46 of the suction conveyor 40 runs intermittently and the bag 10 at the receiving position S1 arrives at the printing position S2 and the suction belt 46 stops intermittently, the printing means 16 is activated and the platen 56, the thermal head, Various information is printed in the printing area 10c by pinching the bag 10 with the above. Since the bottom side of the bag 10 where the printing region 10c is provided at the printing position S2 is placed on the bag conveyance table 42 and supported flatly, good printing is achieved by the printing means 16. Further, when the bag 10 is transported from the receiving position S1 to the printing position S2, the first suction port 46a communicates with the first long hole 54a of the second suction chamber 50 to hold the bag 10 on the bag transport surface. Therefore, the bag 10 can be accurately printed on the print region 10c without being displaced during the conveyance. When the bag 10 at the receiving position S1 is conveyed toward the printing position S2, the bag taking-out means 14 is operated and the bag 10 taken out from the bag stacking portion 12 is delivered to the receiving position S1. At this time, since the second suction port 46b of the suction belt 46 has arrived at the receiving position S1, the second suction port 46b communicated with the second long hole 54b of the first suction chamber 48 at the receiving position S1. The bag 10 is sucked and held on the bag transport surface of the suction belt 46 by the acting suction force.

  When the suction belt 46 runs intermittently, the bag 10 at the printing position S2 arrives at the filling standby position S3, and the suction belt 46 stops intermittently, the first and second bag mouth holding members of the bag mouth portion holding means 24. 64 and 68 are lowered from the release position to the holding position, and the positioning extension 10a of the bag 10 that has arrived at the filling standby position S3 is sandwiched between the conveyor frame 44 and held. When the bag 10 is transported from the printing position S2 to the filling standby position S3, the first suction port 46a communicates with the first long hole 54a of the third suction chamber 52 and sucks and holds the bag 10 on the bag transport surface. Since the operation is maintained, the bag 10 is stopped at a position where the center of the positioning extension portion 10a in the opening width direction coincides with the center of the bread bread conveyance path without being displaced during conveyance.

  After the bag 10 is held by the suction conveyor 40 to the filling standby position S3 and the positioning extension 10a is held by the first and second bag opening holding members 64, 68, the third suction chamber 52 is held. Is switched to the second state, the suction force does not act on the bag 10 at the filling standby position S3 via the first suction port 46a, and the suction holding state of the bag 10 is released. At this time, since the second long hole 54b of the third suction chamber 52 is closed by the suction belt 46 (see FIG. 3), even if the third suction chamber 52 is switched to the second state, the filling standby position S3. A suction force does not act on the bag 10 located in the bag 10 so that the bag 10 can be easily opened. Further, by blowing the pressure air from the first air blowing means 72, the bag mouth portion 10e facing the upstream side in the bread bread transport direction is preliminarily opened, and the second bag mouth holding means 24 in the bag mouth portion holding means 24 is held. The members 68 and 68 are lifted to release the holding on both sides in the width direction of the positioning extension 10a.

  At the timing after the bag opening 10e is preliminarily opened, the bag opening means 22 moves forward from the initial position, and the downstream ends of the respective opening members 82a, 82a, 82b, 82b enter the bag from the bag opening 10e. As the opening members 82a, 82a, 82b, and 82b move forward, the downstream end portions of the upper opening members 82a and 82a move upwardly away from the lower opening members 82b and 82b. The bag mouth portion 10e is greatly expanded into a substantially rectangular shape through which the bread 18 can pass and is held open (see FIG. 4). When the pressing members 88, 88 of the bag holding means 26 are moved from the release position to the holding position, the bag opening 10e is expanded so that the positioning extension portion rises outside the lower opening members 82b, 82b. 10a is sandwiched and held between the lower opening members 82b and 82b and the pressing members 88 and 88 from inside and outside. Further, when the bag 10 is held by the bag holding means 26, the first bag mouth holding member 64 in the bag mouth part holding means 24 is lifted to release the holding in the opening width direction center of the positioning extension 10a. At the same time, the whole bag 10 is lifted from the bag conveying surface by the blowing of the pressure air from the second air blowing means 74, and the bag 10 is held open at the filling position S4. That is, the next bag 10 is allowed to be conveyed to the filling standby position S3 on the lower side of the bag 10 waiting for the filling of the bread 18 at the filling position S4.

  The bread 18 fed by the push conveyor 28 passes between the four opening members 82a, 82a, 82b, 82b in the bag opening means 22 holding the bag mouth portion 10e and is directed toward the bag bottom side. Filled. Since the next bag 10 is allowed to be transported to the lower side of the bag 10 in which the bread 18 is being filled at the filling position S4, the bag printed at the printing position S2 by intermittently running the suction belt 46. 10 is conveyed to the filling standby position S3. When the next bag 10 is transported to the filling standby position S3, the positioning extension 10a is held by the bag mouth holding means 24 as described above. Although the third suction chamber 52 is switched to the second state, when the bag 10 is transported from the printing position S2 to the filling standby position S3, the third suction chamber 52 is moved along with the travel of the suction belt 46. The second suction port 46b communicates with the second long hole 54b, and the bag 10 is prevented from being displaced during conveyance.

  The pressing members 88, 88 of the bag holding means 26 are moved from the holding position to the release position and the holding of the bag 10 is released in accordance with the time when the bread 18 fed by the feeding conveyor 28 reaches the bottom of the bag. Then, the bag 10 is carried out toward the sealing part together with the bread 18 fed by the pushing member 80 of the pushing conveyor 28. Further, the bag opening means 22 moves backward to the initial position, so that the downstream end portions of the upper opening members 82a and 82a are close to the lower opening members 82b and 82b and return to the original posture, so that the next bread Wait for 18 filling.

  In the bag filling machine of the embodiment, printing is performed on the bag 10 before filling the bread 18, so printing can be performed with the printing surface of the bag 10 being flat and stable, and good printing can be obtained. Further, by adopting a thermal printer as the printing unit 16, better printing can be performed.

  In the bag filling machine of the embodiment, when the bread 10 pushed by the push conveyor 28 is filled into the bag 10, the left and right side portions of the bag 10 in which the bag opening 10 e is held open by the bag opening means 22. Since the bag is held by the bag holding means 26, the bag 10 can be prevented from moving with the bread 18 to the downstream side. In addition, since the bag side portion is held by the bag holding means 26 that prevents the bag 10 from moving downstream during filling of bread, the first bag mouth portion holding means 58 of the bag mouth portion holding means 24 is used. After releasing the holding of the positioning extension portion 10a, the next bag 10 is conveyed in the holding state to the lower filling standby position S3 of the bag 10 being filled with bread and filled with the next bread 18 The bag 10 can be prepared and it can respond to the speed-up of the bagging process of the bread 18. Further, after the bag 10 taken out by the bag take-out means 14 is sucked and transported to the filling standby position S3, the suction holding with respect to the bag 10 is released only at the filling standby position S3. The bag 10 can be accurately conveyed to the filling standby position S3 without being displaced during conveyance, and the bag opening portion 22 can be smoothly opened by the bag opening means 22.

Moreover, as a structure of only the 1st bag mouth holding | maintenance means 58, when pressing and holding the positioning extension part 10a of the bag 10 from upper direction with a plate-shaped bag mouth holding member, the width | variety of a bag mouth holding member is made wide. By doing so, the positioning extension 10a can be reliably held.
(2) The bag mouth portion holding means 24 may employ a configuration in which the lower surface of the positioning extension 10a is sucked and held from below by suction means such as a suction cup.
(3) The bag holding means 26 may be configured to suck and hold the inside or the outside of the bag 10 only by suction means such as a suction cup without using the bag opening means 22 together. Further, when the inside of the bag 10 is adsorbed, the opening member 82a, 82b of the bag opening means 22 is formed as a suction chamber having a thin double structure and an internal air chamber, so that the bag opening means is used as a bag holding means. Can function.
(4) When the bag holding means 26 is configured to hold the bag 10 between the pressing member 88 and the bag opening means 22, the pressing member 88 can be moved in the vertical direction, and the upper side of the bag 10 is the bag opening means. It is good also as a structure hold | maintained on both sides from 22 up and down directions.

(5) The printing unit 16 is arranged at a position where printing can be performed on the uppermost bag 10 stacked and stored in the bag stacking portion 12, and after printing on the uppermost bag 10 of the bag stacking portion 12, the printing is performed. A configuration in which the bag 10 taken out by the bag taking-out means 14 can be adopted. In addition, the printing unit 16 can be arranged at a position where printing can be performed on the bag 10 delivered to the receiving position S1 of the bag conveying unit 20. Thus, if the printing means 16 is arranged so as to print on the bag stacking portion 12 or the bag 10 located at the receiving position S1, the conveyance path by the bag conveyance means 20 can be shortened to reduce the size of the bag filling machine. it can.
(6) The mounting surface of the bag mounting table 30 in the bag stacking section 12 is not limited to being horizontal, but may be inclined, or the bag mounting table 30 is arranged vertically and the bag 10 is suspended by the support pins 30a and 30a. It may be stored in a lowered state.
(7) The suction belt 46 is configured such that a plurality of suction belts divided in accordance with the number of the suction chambers 48, 50, 52 are arranged in parallel so that each suction belt can run independently. A plurality of bags 10 can be accumulated upstream from the filling standby position S3 in the bag conveying direction to cope with further speeding up of the bag filling process.
(8) The suction conveyor 40 is provided with one suction chamber from the upstream side to the downstream side in the bag conveyance direction, and a long hole provided at a position corresponding to the filling standby position S3 in the suction chamber is opened and closed by an opening / closing member. By adopting, it is possible to perform suction holding and suction release of the bag 10 conveyed to the filling standby position S3.
(9) In the embodiment, the third suction chamber 52 is switched between the first state and the second state in accordance with the time when the bag 10 at the filling standby position S3 is expanded by the bag opening means 22, thereby filling the filling standby position. Although the suction force is not applied to the bag 10 in S3 (the suction force is reduced to 0), the suction force is reduced to a small value that does not hinder expansion of the bag 10 by the bag opening means 22. There may be. For example, the distance between the long holes 54a and 54b of the third suction chamber 52 and the suction ports 46a and 46b of the suction belt 46 is separated to reduce the suction force, or the negative pressure formed in each of the long holes 54a and 54b. The suction force acting on the corresponding suction ports 46a and 46b may be reduced by changing the above.
(10) With respect to the suction force acting on the bag conveyance surface of the suction belt 46, the bag 10 is not displaced during travel of the suction belt 46, and the expansion by the bag opening means 22 of the bag 10 at the filling standby position S3 is obstructed. If it is set to a value that does not, the configuration in which the suction force is constant can be adopted without switching the third suction chamber 52 between the first state and the second state or reducing the suction force.
(11) The pre-opening means for pre-opening the bag 10 may preliminarily open the upper film adsorbed by an electrostatic charging member or an adsorbing member such as an adsorbing cup while being separated from the lower film.
