JP 2003-34302 A

  In the spoon bagging apparatus having the above configuration, the upper and lower two films and the spoon are transported together, but the spoon moves with respect to the film during transport, and a part of the spoon is positioned at the welded portion of the film. May end up. In such a state, two films cannot be welded, resulting in a defective product. In addition, since the two sides of the upper and lower films with the spoon in between are welded on both sides in the left and right direction and both ends in the front and rear direction, the bag is packed with something other than a spoon, for example, powder together with the spoon. Otherwise, a part of the powder falls off between the two films before the films are welded. For this reason, there existed a problem that it was difficult to pack things other than spoons, such as powder, with a spoon.

In order to solve the above problem, the present invention provides a bag formed by closing the left and right side portions and the lower end portion of two sheets facing each other from a top opening portion thereof to an elongated tableware such as a spoon. A bag transporting means for transporting the bag to a predetermined receiving position, and a tableware transporting means for transporting the tableware to a predetermined delivery position defined in the vicinity of the receiving position. And tableware loading means for moving the tableware conveyed to the delivery position to a loading position above the opening of the bag conveyed to the receiving position, the tableware loading means at the loading position, The tableware is held so that the direction is inclined with respect to the horizontal direction, the held tableware is dropped naturally, and is put into the bag from its upper end opening. .
In this case, the bag conveying means has a pair of bag holding portions that respectively hold the left and right side portions of the two sheets of the bag, and at least one of the pair of bag holding portions is in the left-right direction with respect to the other. It is desirable to keep the opening of the bag open by moving closer to a predetermined distance.
The tableware throwing means has a rotating arm that can rotate around a base end portion, and a holding portion that is provided at a distal end portion of the rotating arm and holds the tableware, and the holding portion is positioned at the delivery position. It is desirable that the rotary arm rotate the tableware to the loading position after holding the tableware.

According to the present invention having the above-described characteristic configuration, the bag conveying means conveys the bag to the receiving position. On the other hand, the tableware conveying means conveys tableware such as a spoon to the delivery position. The tableware throwing means moves the tableware conveyed to the delivery position to the loading position above the opening of the bag and then naturally drops the tableware. Thereby, tableware can be thrown in from the upper end opening part in a bag.
Here, since the left and right sides and the lower end of the bag are closed in advance, the bag can be filled with something other than a spoon such as powder. In addition, when the tableware is put into the bag, the longitudinal direction of the tableware is inclined with respect to the horizontal direction, and the horizontal length of the tableware is shortened by the amount of inclination. Therefore, tableware can be easily put into the bag. And the thrown-in tableware falls to the predetermined position in a bag. That is, when the powder or the like is packed in the bag, it falls to the top of the packed powder or the like, and when the powder or the like is not packed, it falls to the lower end of the bag. Therefore, when the upper end opening of the bag is closed by welding or the like after the tableware is packed in the bag, the situation where the tableware is positioned at the welding portion is not caused.

The best mode for carrying out the present invention will be described below with reference to the drawings.
First, description will be made of a bag in which a tableware bagging device according to the present invention is to be loaded with a spoon (tableware). As shown in FIGS. 1 and 2, the bag 1 has front and rear sheets 1a and 1b. The front and rear seats 1a and 1b are arranged to face each other in the front and rear direction. Moreover, the sheets 1a and 1b are arranged so that the upper end portions are in contact with each other, and the interval between the lower portions of the contact portions is expanded downward. A bottom sheet 1c is provided between the lower ends of the sheets 1a and 1b. Thereby, the lower end part of sheet | seat 1a, 1b is closed. The bottom sheet 1c may be formed separately from the front and rear sheets 1a and 1b, and both ends in the front-rear direction may be fixed to the lower ends of the front and rear sheets 1a and 1b. By bending the sheet, the front and rear sheets 1a and 1b and the bottom sheet 1c are integrally formed.

Side sheets 1d and 1e are respectively disposed in triangular portions formed by the left and right side portions of the front and rear sheets 1a and 1b and the bottom sheet 1c. The peripheral edges of the side sheets 1d and 1e are fixed to the left and right side parts of the front and rear sheets 1a and 1b and the bottom sheet 1c, respectively, by welding or the like. Thereby, the space between both side portions of the front and rear seats 1a, 1b is closed. The lower end of the front and rear sheets 1a and 1b is closed by the bottom sheet 1c, and the left and right sides of the front and rear sheets 1a and 1b are closed by the side sheets 1d and 1e, thereby opening the upper end of the bag 1 Is configured. In addition, the bottom sheet 1c and the side sheets 1d and 1e are folded at the center in the front-rear direction as shown in FIGS. 8B and 1B, and the bag 1 has a spoon (tableware). Before S and powder P are packed, the bag 1 is folded thinly.

  Of the left and right end portions of the front and rear sheets 1a and 1b, portions located above the side sheets 1d and 1e are fixed by welding or the like. A portion between the front and rear sheets 1a and 1b located between the welded portions is an opening. The front and rear seats 1a and 1b located between the lower ends of the welded portions are provided with a fitting type fastener 1f. When the portions of the front and rear seats 1a, 1b where the fasteners 1f are formed are pushed closer together, the fasteners 1f are fitted together. Thereby, the upper-end opening part of the bag 1 is airtightly closed. On the other hand, when the upper ends of the front and rear sheets 1a and 1b are pulled apart from each other, the fastener 1f is opened and the upper end opening of the bag 1 is opened.

The front and rear sheets 1a and 1b, the bottom sheet 1c, and the side sheets 1d and 1e are made of a single-layer or multi-layer film made of resin. Of course, the sheets 1a to 1e may be made of other materials, for example, a laminate film obtained by laminating a resin film and a metal foil such as aluminum, or paper. Moreover, you may form each sheet | seat 1a-1e with a mutually different material.

The two sheets 1a and 1b are formed in a rectangular shape that is long to the left and right, so that the bag 1 is formed in a rectangular shape that is long to the left and right in the front view. You may form in shapes, such as a square and a trapezoid. Moreover, although the side view shape of the bag 1 is a substantially triangle, you may make it a rectangle long vertically. Further, the bag 1 may be formed by folding and stacking one sheet at the center and fixing the left and right sides thereof. Thus, the shape of the bag 1 is arbitrary as long as it has an opening at the upper end and the lower end and the left and right sides are closed.

  3A and 3B show a state where the powder P and the spoon S are packed in the bag 1. The powder P is packed in the bag 1 by a predetermined amount. In this embodiment, the powder P is packed in the bag 1 so that the upper surface of the powder P is located slightly below the center between the bottom sheet 1c and the fastener 1f. The spoon S is placed on the powder P in a state of being substantially horizontal with the longitudinal direction thereof set to the left and right direction. After the powder P and the spoon S are packed in the bag 1, the fastener 1f is closed, and then the upper ends of the front and rear sheets 1a, 1b located above the fastener 1f are fixed by welding or the like. Thereby, a product in which the powder P and the spoon S are packed in the bag 1 is manufactured.

  Next, an embodiment of a tableware bagging apparatus according to the present invention will be described. FIG. 4 shows a spoon bagging device (tableware bagging device) 10 according to the present invention. This bagging device 10 is for packing powder P and spoon S into the bag 1, and includes a rotary table 20, a belt conveyor 30 arranged around the rotary table 20, spoon conveying means (tableware conveying means). ) 40, spoon input means (tableware input means) 50 and product carry-out means 60. Note that the spoon bagging apparatus 10 according to the present invention does not necessarily have to be configured so as to pack anything other than the spoon S, such as powder, and may pack only the spoon S. Moreover, as tableware stuffed into the bag 1, long tableware other than the spoon S, for example, a fork or chopsticks may be used.

  The turntable 20 has a circular shape in plan view, and is arranged with its axis line directed in the vertical direction. The rotary table 20 is intermittently rotated by a rotational drive source (not shown) such as a motor at predetermined angles about the axis of the rotary table 20, in this embodiment, every 45 °. Assuming that the vicinity of a predetermined part of the rotary table 20 (the lower part in FIG. 4 in this embodiment) is the first station A1, the vicinity of the part that is 90 ° clockwise from the first station A1 is The second station A2, the third and fourth stations A3 and A4 are set every 45 ° from the second station A2, and the vicinity of the portion 90 ° away from the fourth station A4 is the fifth station A5. The vicinity of the part 45 ° away from the fifth station 5A is the sixth station A6.

  In 1st station A1, the bag 1 conveyed by the belt conveyor 30 is delivered to the turntable 20 side. That is, the belt conveyor 30 extends from the first station A1 toward the radially outer side of the rotary table 20, and conveys the bag 1 toward the first station A1. The bag 1 has its end on the opening side facing forward in the conveying direction of the belt conveyor 30 (left side in FIG. 5), and its end on the bottom 1c side of the end of the subsequent bag 1 on the opening side. It is conveyed in a state of being stacked on top. You may convey the bag 1 in the state which the edge part by the side of the bottom part 1c of the front bag 1, and the edge part by the side of the opening part of the back bag 1 contacted, without overlapping the edge part.

  A rotary transfer means 31 is provided between the front end of the belt conveyor 30 in the transport direction and the rotary table 20. The rotary transfer means 31 has a suction part 31a. The adsorbing part 31a adsorbs the bag 1 conveyed to the front end by the belt conveyor 30, that is, the front sheet 1a of the bag 1 located at the head. Thereby, the top bag 1 is held. Here, since the bag 1 is placed on the belt conveyor 31 with the front sheet portion 1a facing upward, the suction portion 31a sucks and holds the front sheet 1a, but the bag 1 then holds the sheet portion 1b. When it is placed on the belt conveyor 31 in an upward direction, the suction portion 32a holds the rear sheet portion 1b by suction. The rotation transfer means 31 rotates by a predetermined angle around the rotation shaft 31b while holding the bag 1. As a result, the bag 1 stands vertically with its opening positioned on the upper side, and the rear sheet portion 1 b is opposed to the outer peripheral surface of the turntable 20.

  The rotary table 20 is provided with a plurality of holding means 32. Each holding means 32 is arranged away from each other in the circumferential direction of the turntable 20. Moreover, the central angle between the two holding means 32 adjacent to each other in the circumferential direction is set to the same angle as the intermittent rotation angle of the rotary table 20. Therefore, in this embodiment, eight holding means 32 are provided. Moreover, of the eight holding means 32, one of the holding means 32 is positioned at the first station A1 in accordance with the rotation of the rotary table 20, and five of the remaining seven holding means 32 are the first ones. 2 to 6 stations A2 to A6, respectively, and the remaining two holding means 32 are disposed between the first and second stations A1 and A2 and between the fourth and fifth stations A4 and A5, respectively. ing.

  As shown in FIG. 6, the holding means 32 has a pair of left and right clamping parts (bag holding parts) 32A and 32B. The holding portions 32A and 32B are arranged so as to be movable in the tangential direction of the rotary table 20, that is, in the left-right direction of the bag 1 after being transferred by the rotary transfer means 31, and the bag 1 is moved by the rotary transfer means 31. When transported to a position opposite to the outer peripheral surface of 20, they approach each other and sandwich the left and right side portions of the bag 1, which is also slightly lower than the fastener 1 f. Thereby, the bag 1 is held by the rotary table 20. You may make it hold | maintain the bag 1 by adsorb | sucking the right-and-left both sides of the front sheet | seat 1a or the right-and-left both sides of the back sheet | seat 1b without pinching by the clamping parts 32A and 32B. Since the bag 1 is held by the holding means 32, when the rotary table 20 rotates, the bag 1 rotates following the rotation table 20. The bag 1 is held in a state where the bag 1 is separated from the outer peripheral surface of the turntable 20 by a predetermined distance and the upper end portion of the rear sheet portion 1 b is opposed to the outer peripheral surface of the turntable 20. Of course, the opening of the bag 1 is located at the upper end of the bag 1.

  When the turntable 20 rotates 90 °, the bag 1 is conveyed to the second station A2. In the second station A2, the opening of the bag 1 is opened. As shown in FIGS. 7 and 8, an opening means 33 and an air blowing nozzle 34 are disposed at the second station A2. The opening means 33 has a pair of suction portions 33A and 33B. The pair of suction portions 33A and 33B are provided so as to face each other in the radial direction of the turntable 20 and to be movable in the same direction. When the bag 1 is conveyed to the second station A2, the pair of suction portions 33A and 33B move toward each other and come into contact with the front sheet 1a and the rear sheet 1b, respectively. And one suction part 33A vacuum-sucks the center part of the left-right direction of the upper end part of the front sheet | seat part 1a. The other suction portion 33B vacuum-sucks the central portion in the left-right direction of the upper end portion of the rear sheet portion 1b. Thereafter, the pair of suction portions 33A and 33B move away from each other to a predetermined position. Thereby, the upper-end opening part of the bag 1 is opened (refer FIG. 8 (B)). Here, when the upper end opening portion of the bag 1 is opened, the width in the left-right direction of the upper end portion of the bag 1 is reduced accordingly. Therefore, when the suction portions 33A and 33B move away from each other, the sandwiching portions 32A and 32B move closer to each other accordingly.

  The air blowing nozzle 34 is disposed with its blowing port 34a facing downward, and the blowing port 34a is located at the center of the opening of the bag 1 in plan view. Therefore, when air blows out from the blowout port 34a, the air enters the bag 1 and spreads the folded bottom sheet 1c and side sheets 1d and 1e. Then, the bag 1 is inflated into a predetermined shape. When the air blowing nozzle 34 blows air for a predetermined amount or for a predetermined time, the air blowing nozzle 34 stops blowing the air.

When the opening of the bag 1 is widened and the bag 1 is inflated, the suction portions 33A and 33B stop the vacuum suction, move away from each other, and separate from the front and rear sheets 1a and 1b in the left-right direction. Even if the suction portions 33A and 33B are separated from the bag 1, the opening of the bag 1 is maintained in an open state. This is because when the opening portion of the bag 1 is opened, the sandwiching portions 32A and 32B move close to each other and remain in that position, thereby maintaining the opening portion of the bag 1 in an open state. The suction portions 33A and 33B separated from the bag 1 return to their original initial positions. The suction portions 33A and 33B that have returned to the initial position stand by until the next bag 1 is conveyed to the second station A2.

If the opening of the bag 1 is open as shown in FIG. 12 in the initial state, the opening means 33 and the air blowing nozzle 34 need not be provided. In addition, when the opening portions of the bag 1 can be opened by moving the holding portions 32A and 32B closer to each other in the left-right direction while holding the left and right side portions of the bag 1, the opening means 33 and the air blowing nozzle are not necessarily used. 34 need not be provided.

  The bag 1 whose opening is opened in the second station A2 is conveyed to the third station A3 by the rotation of the rotary table 20. In the third station A3, as shown in FIG. 9, a predetermined amount of powder P is charged into the bag 1 by the powder charging means 35. Needless to say, when a bag other than the powder P is packed in the bag 1, a loading unit for loading an object to be packed into the bag 1 is provided instead of the powder loading unit 35. The powder input means 35 has a hopper 35A. The hopper 35A stores the powder P therein. An opening 35a is provided at the lower end of the hopper 35A, and the opening 35a is opened and closed by a door 35b. By opening and closing the door 35b for a predetermined time, a predetermined amount of the powder P naturally falls from the lower end opening 35a of the hopper 35A.

  A chute 35B is disposed below the hopper 35A. The chute 35B is arranged so that the rear end portion receives the powder dropped from the hopper 35A. The chute 35B is inclined so as to form a downward slope toward the front. Therefore, the powder P dropped from the hopper 35A to the rear end portion of the chute 35B slides down on the chute 35B. A door 35c is provided below the front end of the chute 35B. When the door 35c is opened, the powder P naturally falls from the front end opening 36d of the chute 35B. The powder P that has fallen naturally enters the bag 1 through the tapered cylindrical guide 35C that decreases in diameter downward. Thereby, a predetermined amount of the powder P is packed in the bag 1.

  The bag 1 filled with the powder P is transported from the third station A3 to the fourth station A4 as the rotary table 20 rotates. The position of the bag 1 when transported to the fourth station A4 is the receiving position. Therefore, in this embodiment, the belt conveyor 30, the rotation transfer means 31, the holding means 32, and the rotary table 20 constitute a bag conveying means for conveying the bag 1 to the receiving position. Of course, the bag conveying means is not limited to the one having the above-described configuration, and other various types can be adopted.

In the fourth station A4, the spoon S is put into the bag 1 conveyed to the receiving position as follows. That is, a table 70 is provided in the vicinity of the rotary table 20 in front of the fourth station A4 (upward in FIG. 4). On this table 70, a spoon input means (tableware input means) 50 is provided, and a spoon transfer means (tableware transfer means) 40 is provided on the right side of the spoon input means 50 in FIG.

The spoon conveying means 40 has a hopper 41, a chute 42, a rotary feeder 43, and a straight feeder 44. The hopper 41 stores a large amount of spoon S therein. From the hopper 41, the spoon S is discharged onto the chute 42 at a substantially constant rate. The chute 42 is disposed between the hopper 41 and the rotary feeder 43 and has a downward slope from the hopper 41 side toward the rotary feeder 43 side. Therefore, the spoon S discharged from the hopper 41 onto the chute 42 slides down on the chute 42 and reaches the rotary feeder 43. The rotary feeder 43 is configured to move the article in the circumferential direction of the rotary feeder 43 by vibration and to make a predetermined posture. The spoon S sent in a random posture from the chute 42 is used for its scooping portion (head). Top with the handle on the bottom. The rotary feeder 43 having such a function is a known one, and its structure is not important in the present invention. Therefore, description of the detailed structure of the rotary feeder 43 is omitted.

  As shown in FIG. 10, the rectilinear feeder 44 has a guide portion 44A. The guide portion 44 extends horizontally in the tangential direction of the rotary table 20, and the spoon S aligned in a fixed posture by the rotary feeder 43 is sequentially transferred by the rotary feeder 43 to the rear end portion away from the rotary table 20. Is done. Therefore, the spoon S is transferred to the guide portion 44A in an upright state with the scooping portion facing upward. The spoon S transferred to the rear end portion of the guide portion 44A is transferred to the tip end side with the vibration of the guide portion 44A. The rectilinear feeder 44 having such a function is known, and its structure is not important in the present invention. Therefore, description of the detailed structure of the rectilinear feeder 44 is omitted.

  The spoon S transferred to the tip of the guide portion 44 </ b> A is stopped by the first stopper 45. The position of the spoon S at this time is the delivery position. The first stopper 45 is movable between a stop position shown in FIG. 12 and a standby position separated from the stop position by a predetermined distance upward in FIG. 12 (a direction away from the rotary table 20 in the radial direction). It is. The first stopper 45 prevents the spoon S from moving forward of the guide portion 44A when it is at the stop position, and allows the spoon S to move forward when it is positioned at the standby position.

  The spoon throwing means 50 has a movable part 51. The movable portion 51 is movable in the longitudinal direction of the guide portion 44A between a retracted position indicated by a solid line and an advanced position indicated by an imaginary line in FIG. The movable portion 51 is provided with a base end portion (left end portion in FIG. 11) of the rotary arm 52 so as to be rotatable about a horizontal axis extending in a direction orthogonal to the longitudinal direction of the guide portion 44A. The rotating arm 52 can rotate between a holding position indicated by a solid line and a release position indicated by an imaginary line in FIG.

  The distal end portion of the rotating arm 52 protrudes from the movable portion 51, and a pair of sandwiching claw portions (holding portions) 52a and 52b are provided at the distal end portion. The pair of clamping claws 52a and 52b can move toward and away from each other in the horizontal direction perpendicular to the longitudinal direction of the guide portion 44A. The pair of clamping claws 52a and 52b may be capable of moving close to and away from each other without allowing any of them to move close to and away from each other. When the movable portion 51 moves to the forward movement position in a state where the rotary arm 52 is located at the clamping position, the handle portion of the spoon S is located between the pair of clamping claw portions 52a and 52b. It is arranged to enter. When the handle portion of the spoon S enters between the pair of sandwiching claws 52a and 52b, when the pair of sandwiching claws 52a and 52b move closer, the pair of sandwiching claws 52a and 52b are positioned at the delivery position. Hold the handle of the spoon S. When the clamping claws 51a and 51b clamp the handle portion of the spoon S, the first stopper 45 moves to the standby position, and the spoon S can move forward from the guide portion 44A. Therefore, when the movable part 51 moves to the retracted position, the spoon S is detached from the guide part 44A. The spoon S may be held by other holding means instead of being held by the pair of holding claws 52a and 52b.

Here, when the spoon S positioned at the delivery position (spoon S positioned in front of the guide portion 44A) is disengaged forward from the guide portion 44A, the spoon S remaining in the guide portion 44A freely moves forward. There is a possibility that the spoon S located at the head may come off from the guide portion 44A and fall. In order to prevent such inconvenience, a second stopper 46 is provided. The second stopper 46 can move between the standby position and the stop position in the same manner as the first stopper 45, and at the same time as the first stopper 45 moves from the stop position to the standby position or slightly before that, To the stop position. The second stopper 46 positioned at the stop position prevents the spoon S adjacent after the spoon S positioned at the transfer position from moving forward. When the first stopper 45 moves to the stop position after the movable part 51 has moved to the retracted position, the second stopper 46 moves from the stop position to the standby position. As a result, the spoon S in the guide portion 44A can be moved forward, and the foremost spoon S in the guide portion 44A is transferred to the delivery position by the rectilinear feeder 44. Then, it is stopped by the first stopper 45.

  When the movable part 51 is in the retracted position and the rotating arm 52 is in the clamping position, the spoon S is clamped vertically by the pair of clamping claws 52a and 52b. When the rotary arm 52 rotates from the clamping position to the release position, the spoon S also rotates together with the rotary arm 52 and stops. The position of the spoon S at this time is the charging position. Here, if the angle between the holding position and the release position of the rotary arm 52 is θ, the angle θ is set to an angle smaller than 90 °, which is about 60 ° to 80 °. Therefore, when the rotary arm 52 is rotated to the release position and thereby the spoon S is positioned at the loading position, the spoon S is inclined by (90−θ) ° with respect to the horizontal direction. In particular, in this embodiment, the spoon S is inclined with the scooping portion up and the handle portion down. The spoon S may be inclined so that the scooping portion is on the bottom and the handle portion is on the top.

  When the spoon S is positioned at the charging position, the entire spoon S is positioned above the opening of the bag 1 in plan view. In particular, in this embodiment, the spoon S is positioned at the center of the state opening of the bag 1. Therefore, when the clamping claws 52a and 52b are separated from each other to release the handle of the spoon S, Spoon S falls naturally and enters bag 1. And it rides on the powder P in a substantially horizontal state. In this way, the powder P and the spoon S are packed in the bag 1. The rotary arm 52 that has released the spoon S rotates back from the release position to the clamping position, and the spoon throwing means 50 returns to the original state indicated by the solid line in FIG. Thereafter, by repeating the above operation, the insertion of the spoon S into the bag 1 is repeated.

  The operations of the first stopper 45, the second stopper 46, the movable portion 51, the rotating arm 52, and the clamping claws 52a and 52b are controlled by various sensors and a computer (not shown) to which the sensors are connected. However, the control method is a combination or change of known control methods, and is not important in the present invention. Therefore, detailed description of the control method is omitted.

  The bag 1 filled with the powder P and the spoon S is conveyed from the fourth station A4 to the fifth station A5 as the rotary table 20 rotates. In the fifth station A5, the upper end portion of the bag 1, that is, the range surrounded by the imaginary line in FIG. 3A, is fixed by fixing means (not shown) such as welding means. . As a result, a product in which the bag 1 is filled with the powder P and the spoon S is completed.

The fixing portion of the upper end portion of the bag 1 is spaced upward from the fastener 1f. Therefore, the fixed part can be cut off from the bag 1 by cutting the part between it and the fastener 1f. In a state where the fixing portion is cut off, the fastener 1f can be opened to open the opening of the bag 1 by pulling the front and rear sheets 1a, 1b above the fastener 1f. In this state, the spoon S can be taken out from the bag 1, and the powder P can be taken out from the bag 1 with the spoon S. On the other hand, the opening of the bag 1 can be closed by fitting the fastener 1f.
