  Embodiments of the present invention will be described below with reference to the drawings. However, the embodiments described below are given various technically preferable limitations for carrying out the present invention, but the scope of the present invention is not limited to the following embodiments and illustrated examples.

1. Packaging Device FIG. 1 is a schematic side view of a packaging device 1. FIG. 2 is a cross-sectional view taken along the line II-II shown in FIG.

The packaging device 1 is a device for individually packaging the rod-shaped articles 2.
The rod-shaped article 2 has a magnetic body 3 at one end, and the other part 4 is a non-magnetic body. More specifically, the rod-shaped article 2 is a ball-point pen refill, and the resin-made ink storage cylinder 5 and the ink therein are nonmagnetic, and a metal ball-point pen tip attached to one end of the ink storage cylinder 5. Reference numeral 6 denotes the magnetic body 3.

  The packaging device 1 includes a lower film transporter 10, an upper film transporter 15, a hopper (article storage unit) 20, an article supply unit 30, a transport base 40, an auxiliary transporter 50, a side sealer 70, an end sealer 80, and a foreign matter detection unit. 90, a control unit 95, and the like.

  The lower film transporter 10 transports the belt-shaped film 8 while pulling the film with a driving roller (not shown) disposed downstream, and includes a guide roller 11, a feeding roller 13, and a feed motor 14. The upper film transporter 15 transports the strip film 9 so that the strip film 9 is partially parallel to the strip film 8, and includes a guide roller 16, a feed roller 18, and a feed motor 19.

  A conveying table 40 is provided on the downstream side of the guide roller 11, a side sealer 70 is provided on the downstream side of the conveying table 40, and an end sealer 80 is provided on the downstream side of the side sealer 70. A guide roller 16 is provided on the upstream side of the side sealer 70. The guide roller 16 is disposed on the downstream side of the guide roller 11.

The strip films 8 and 9 wound around the original rolls 12 and 17 are guided from the original rolls 12 and 17 to the feeding rollers 13 and 18, and the feeding rollers 13 and 18 are driven to rotate by the feed motors 14 and 19. Thus, the strip films 8 and 9 are continuously conveyed at a constant speed.
The belt-shaped film 8 is guided from the feeding roller 13 to the guide roller 11, and is guided in the horizontal direction from the guide roller 11 in the order of the conveyance table 40, the side sealer 70, and the end sealer 80. Moreover, the strip | belt-shaped film 8 passes on the conveyance base 40 to the downstream side in the state supported by the conveyance base 40 from the bottom.

  The belt-like film 9 is guided from the feeding roller 18 to the guide roller 16, and is guided in the horizontal direction from the guide roller 16 in the order of the side sealer 70 and the end sealer 80. The belt-like film 9 and the belt-like film 8 are opposed to each other in the path from the guide roller 16 to the end sealer 80.

  A hopper 20 and an article supply machine 30 are provided above the transport table 40. In the hopper 20, a plurality of bar-shaped articles 2 are stored in a lying state. The article supply device 30 supplies the bar-shaped articles 2 in the hopper 20 one by one onto the strip-shaped film 8 on the transport table 40. The rod-shaped article 2 placed on the band-shaped film 8 is conveyed downstream together with the band-shaped film 8 and is sandwiched between the band-shaped films 8 and 9 when passing through the guide roller 16. The rod-shaped article 2 is conveyed at the same speed as the band-shaped film 8 by the auxiliary conveyance device 50 so that the rod-shaped article 2 does not slip or jump up from the band-shaped film 8 while moving on the conveyance table 40.

The strip films 8 and 9 are conveyed from the guide roller 16 in the order of the side sealer 70 and the end sealer 80. When the strip films 8 and 9 pass through the side sealer 70, both side portions of the strip films 8 and 9 are continuously sealed and joined by the side sealer 70. Further, the strip films 8 and 9 are periodically sealed by the end sealer 80. Specifically, the end sealer 80 sandwiches the belt-like films 8 and 9 up and down between the bar-shaped article 2 passing through the end sealer 80 and the next bar-shaped article 2 reaching the end sealer 80. To do. Of the belt-like films 8 and 9, a portion sealed by the end sealer 80 is referred to as a planned sealing portion 7.
As described above, a drive roller (not shown) is provided on the downstream side of the end sealer 80, and the drive roller is a feed motor 14, a feed motor 19 or a transport motor (the transport motor is controlled by a control unit 95 described later). , 19 and the belt-like films 8 and 9 are pulled by the driving roller.
Below, each structure of the packaging apparatus 1 is demonstrated in detail.

2. Hopper As shown in FIGS. 1 and 2, the hopper 20 is disposed above the transport table 40. The upper end of the hopper 20 is open, and the bottom of the hopper 20 is provided in a V-shaped valley so that the width becomes narrower downward. In this hopper 20, a plurality of bar-shaped articles 2 are accommodated in a state of being lying in a posture parallel to the transport direction of the belt-like film 8. The magnetic body 3 of the rod-shaped article 2 in the hopper 20 is directed to the downstream side in the transport direction of the strip film 8.

  A discharge port 21 is formed at the deepest portion of the hopper 20 so as to extend in the transport direction of the strip-shaped film 8. The rod-shaped articles 2 in the hopper 20 are discharged from the discharge port 21 by gravity one by one.

3. Article Supply Machine The article supply machine 30 includes a supply drum 31, a supply motor 35, and a guide 38.
The supply drum 31 and the guide 38 are provided between the hopper 20 and the transport table 40. A plurality of concave portions 32 extending in the axial direction of the supply drum 31 are formed on the outer peripheral surface of the supply drum 31 at equal intervals in the circumferential direction. The supply drum 31 is disposed under the hopper 20 so that the axis thereof is horizontal and parallel to the transport direction of the strip film 8. The outer peripheral surface of the supply drum 31 is positioned immediately below the discharge port 21.

  The supply drum 31 is connected to a supply motor 35 (for example, a servo motor) and is rotationally driven by the supply motor 35. When the supply drum 31 is rotationally driven by the supply motor 35, the recess 32 sequentially passes under the discharge port 21 in the circumferential direction.

  The upper end of the semi-cylindrical guide 38 is disposed in the vicinity of the discharge port 21, and the guide 38 extends downward from the discharge port 21 in the circumferential direction of the supply drum 31. A gap is formed between them.

  The rod-shaped article 2 in the hopper 20 falls from the discharge port 21 and is accommodated in the recess 32 of the supply drum 31 when the recess 32 of the supply drum 31 passes below the discharge port 21. The rod-shaped article 2 is conveyed downward along the guide 38 by the rotation of the supply drum 31. Then, when the rod-shaped article 2 reaches the lower end of the guide 38, it falls from the concave portion 32 onto the strip-shaped film 8.

4). Conveying table The conveying table 40 is provided horizontally below the hopper 20, and moves on the conveying table 40 to the downstream side in a state where the belt-shaped film 8 is in contact with the upper surface of the conveying table 40. A groove 41 extending in the conveyance direction of the belt-like film 8 is formed on the upper surface of the conveyance table 40, and the lower end of the guide 38 and the shaft of the supply drum 31 are arranged above the groove 41. The groove 41 is formed in a V shape in a cross section (see FIG. 2) viewed in the transport direction of the strip film 8 so that the width becomes narrower toward the deep part. A slit 42 is formed at the bottom of the groove 41, leading to the lower surface of the transport table 40. Therefore, the transport table 40 is divided into two by the groove 41 and the slit 42.

  A suction port 43 is formed in the groove 41. The suction port 43 is connected to an air suction machine, and a negative pressure is generated at the suction port 43 by the air suction machine. When the belt-like film 8 passes over the groove 41, the suction port 43 sucks the belt-like film 8 due to negative pressure, so that the central portion of the belt-like film 8 is recessed so as to be deformed into the shape of the groove 41. Then, the rod-shaped article 2 conveyed to the lower end of the guide 38 by the supply drum 31 falls into the groove 41 and fits in the groove 41 while being placed on the belt-like film 8. Thereby, the relative position of the rod-shaped article 2 with respect to the strip-shaped film 8 is determined.

5). Auxiliary conveyance machine The auxiliary conveyance machine 50 includes a plurality of magnets 56 arranged below the belt-like film 8 conveyed downstream from the guide roller 11 and a moving mechanism for moving these magnets 56 in a circular manner. The moving mechanism includes a drive motor 51, sprockets 52 to 54, and an endless chain 55.

  A sprocket 52 is disposed under the carrier 40, a sprocket 54 is disposed under a lower seal plate 71, which will be described later, of the side sealer 70, and a sprocket 53 is disposed under the upstream end of the lower sealer plate 71. It is arranged. The rotation axes of the sprockets 52 to 54 extend in a direction (width direction) perpendicular to the paper surface of FIG. 1, and an endless chain 55 is stretched around the sprockets 52 to 54.

  Here, the part from the sprocket 52 to the sprocket 53 of the endless chain 55 is provided horizontally below the slit 42. The sprocket 52 is disposed below the position between the upstream edge and the downstream edge of the discharge port 21 of the hopper 20 (specifically, the central portion of the discharge port 21), and the sprocket of the endless chain 55 A horizontal portion from 52 to the sprocket 53 extends from below the central portion of the discharge port 21 to the downstream side. Further, a part of the endless chain 55 from the sprocket 53 to the sprocket 54 is inclined downward toward the downstream side.

  The magnets 56 are attached to the endless chain 55 so as to be arranged along the endless chain 55. These magnets 56 are provided in a part of the endless chain 55, but may be provided over the entire circumference. The moving speed of the magnet 56 due to the endless chain 55 orbiting is equal to the conveying speed of the belt-like film 8 by the feed motor 14 and the feeding roller 13.

  The path from the sprocket 52 to the sprocket 53 is called a parallel part 55a, the path from the sprocket 53 to the sprocket 54 is called a downward inclined part 55b, and the path from the sprocket 54 to the sprocket 52 is returned. This is referred to as part 55c. The parallel portion 55 a is parallel to the strip film 8 conveyed downstream from the guide roller 11 and is in the slit 42. The parallel portion 56 a is a proximity portion that is closest to the strip-shaped film 8 in the track of the magnet 56. In addition, the direction of movement of the magnet 56 in the parallel portion 55 a is the same as the direction of conveyance of the strip film 8 on the downstream side of the guide roller 11.

  As shown in FIG. 1, when the magnet 56 is moving in the parallel portion 55 a within the slit 42, the rod-shaped article 2 is supplied onto the band-shaped film 8 by the article supply machine 30. Then, since the magnetic body 3 of the rod-shaped article 2 is attracted to the magnet 56 by the magnetic force of the magnet 56, the rod-shaped article 2 does not jump up from the belt-like film 8. Moreover, since the rod-shaped article 2 moves together with the magnet 56 and the moving speed of the magnet 56 and the conveyance speed of the strip-shaped film 8 are equal, the rod-shaped article 2 does not slide with respect to the strip-shaped film 8 during the movement on the conveyance table 40. . Therefore, it is possible to prevent the stick-shaped article 2 from overlapping the planned sealing portion 7. The strip film 8 is preferably a non-magnetic material so as not to be attracted to the magnet 56.

  When the rod-shaped article 2 reaches the sprocket 53 together with the magnet 56, the magnet 56 moves away from the rod-shaped article 2. This is because the downward inclined portion 55 b is inclined downward and the belt-like film 8 is supported from below by a lower seal plate 71 described later of the side sealer 70.

As shown in FIG. 3, when the rod-shaped article 2 is mistakenly accommodated in the hopper 20 with the magnetic body 3 facing the upstream side in the transport direction of the belt-shaped film 8, the rod-shaped article 2 is supplied by the article feeder 30. Even if it is done, the magnetic body 3 of the rod-shaped article 2 is not attracted to the magnet 56. This is because the last magnet 56 is positioned downstream of the magnetic body 3 of the bar-shaped article 2 in the opposite direction at the timing when the bar-shaped article 2 falls. In particular, since the sprocket 52 is disposed below the discharge port 21 of the hopper 20, the magnet 56 is always positioned on the downstream side of the magnetic body 3 of the rod-shaped article 2 when the opposite-shaped rod-shaped article 2 falls.
Since the magnetic body 3 of the bar-shaped article 2 in the reverse direction is not attracted to the magnet 56, the bar-shaped article 2 is shifted in position because of its light weight, and may overlap the planned sealing site 7. In this case, when the bar-shaped article 2 passes through the inspection point P together with the belt-shaped film 8, the bar-shaped article 2 is detected as a foreign object by the foreign object detection unit 90 described later.

  The endless chain 55 may be replaced with an endless belt or an endless wire, and the sprockets 52 to 54 may be replaced with pulleys.

6). Side Sealer The side sealer 70 includes a pair of lower seal plates 71 and a pair of upper seal plates 72 that are arranged at intervals in a direction perpendicular to the paper surface of FIG. The upper seal plate 72 is disposed on the lower seal plate 71, and when both side portions of the strip films 8 and 9 pass through the gap between the upper seal plate 72 and the lower seal plate 71, the seal plates 71, 72 is heated. Thereafter, both side portions of the belt-like films 8 and 9 are pressed by a pressure roller (not shown) provided on the downstream side of the seal plates 71 and 72. Thereby, the both sides of the strip-shaped films 8 and 9 are sealed.

7). End sealer The end sealer 80 moves the lower crimping portion 81 and the upper crimping portion 82 in the vertical direction by the power of the lower crimping portion 81 and the upper crimping portion 82, the lifting motor 83, and the lifting motor 83, which are brought into and out of contact with each other. A transmission mechanism (not shown) for contact and separation. When the crimping portions 81 and 82 come close to each other, the belt-like films 8 and 9 are sandwiched between the lower crimping portion 81 and the upper crimping portion 82 and heated by these crimping portions 81 and 82. Thereby, the strip | belt-shaped films 8 and 9 are thermocompression bonded.

8). Foreign Object Detection Unit The foreign object detection unit 90 is disposed between the supply drum 31 of the article supply machine 30 and the guide roller 16 above the transport table 40. The foreign matter detector 90 detects the presence or absence of foreign matter on the belt-like film 9 that passes through the inspection point P on the downstream side of the supply drum 31 of the article supply machine 30 and on the upstream side of the guide roller 16. The foreign object detection unit 90 is a reflective optical sensor having a projector that projects light toward the lower band-shaped film 8 and a light receiver that receives reflected light from below. The foreign object detection unit 90 may be a transmissive optical sensor.

  Here, the level of the output signal of the foreign matter detector 90 when foreign matter other than the strip film 8 exists between the strip film 8 and the foreign matter detector 90 is that the foreign matter is between the strip film 8 and the foreign matter detector 90. Is different from the level of the output signal of the foreign object detection unit 90 when it does not exist. Thereby, the presence or absence of a foreign substance can be detected by the foreign substance detection unit 90.

  In addition, when the rod-shaped article 2 is accommodated in the hopper 20 in the opposite direction, when the rod-shaped article 2 in the opposite direction is supplied onto the band-shaped film 8, the rod-shaped article 2 overlaps the planned sealing portion 7 due to the displacement. In this case, the rod-shaped article 2 is detected as a foreign object by the foreign object detector 90 when passing through the inspection location P.

9. Control Unit The control unit 95 is configured by a control circuit having, for example, a programmable logic controller (PLC) and a motor driver.

  The control unit 95 performs synchronous control of the feed motors 14 and 19 and the drive motor 51. More specifically, the feed motor 14 is configured such that the transport speed of the strip film 8 by the feed motor 14, the transport speed of the strip film 9 by the feed motor 19, and the moving speed of the magnet 56 by the drive motor 51 are equal to each other. , 19 and the drive motor 51 are synchronously controlled by the control unit 95.

  The controller 95 controls the drive motor 51 and the supply motor 35 synchronously. Specifically, the drive motor 51 and the supply motor 35 are arranged so that the magnet 56 moves downstream between the sprocket 52 and the sprocket 53 when the recess 32 of the supply drum 31 passes the lower end of the guide 38 in the circumferential direction. Are controlled synchronously by the control unit 95.

  Further, the control unit 95 controls the lifting motor 83 so as to synchronize the lifting motor 83 of the end sealer 80 with the feed motors 14, 17, the supply motor 35, and the driving motor 51. Perform thermocompression bonding and cutting operations. Thereby, the seal | sticker planned site | part 7 is thermocompression-bonded and cut | disconnected sequentially by the end sealer 80. FIG.

  Further, the control unit 95 determines the presence / absence of foreign matter by comparing the output signal of the foreign matter detection unit 90 with a predetermined threshold value in synchronization with the timing when the planned seal portion 7 passes the inspection location P. For example, if the level of the output signal of the foreign matter detection unit 90 exceeds a predetermined threshold at the timing when the planned seal portion 7 passes the inspection location P, the control unit 95 recognizes the presence of the foreign matter, and at that timing, If the level of the output signal of the foreign object detection unit 90 is equal to or less than a predetermined threshold, the control unit 95 recognizes the absence of the foreign object. Note that when the level of the output signal of the foreign object detection unit 90 exceeds a predetermined threshold, the control unit 95 recognizes the absence of the foreign object, and the control is performed when the level of the output signal of the foreign object detection unit 90 is equal to or lower than the predetermined threshold. The unit 95 may recognize the presence of a foreign object.

  When the presence of the foreign matter is recognized by the control unit 95, the control unit 95 temporarily stops the lifting motor 83 immediately before the planned seal site 7 where the foreign matter is present reaches the end sealer 80. Therefore, when the planned sealing site 7 where foreign matter exists passes between the lower crimping portion 81 and the upper crimping portion 82, the planned sealing site 7 is not sealed. Therefore, it is possible to prevent foreign matter from being sandwiched between the lower crimping portion 81 and the upper crimping portion 82.

  Thereafter, the control unit 95 continues to stop the lifting motor 83 until the absence of a foreign object is recognized by the control unit 95. When the control unit 95 recognizes the absence of foreign matter, the control unit 95 restarts the lifting motor 83 immediately before the planned seal portion 7 where no foreign matter is present reaches the end sealer 80.

  When the controller 95 recognizes the absence of a foreign object, not only the lifting motor 83 of the end sealer 80 but also the feed motors 14 and 19, the supply motor 35 and the drive motor 51 may be stopped by the controller 95. At this time, an alarm device (for example, an alarm lamp or an alarm speaker) connected to the control unit 95 may be activated by the control unit 95.

10. Effect According to the above embodiment, since the rod-shaped article 2 is conveyed to the downstream side at the same speed as the strip-shaped film 8 by the movement of the magnet 56, the position of the rod-shaped article 2 with respect to the strip-shaped film 8 is relatively shifted. Can be prevented.

  When the magnetic body 3 of the rod-shaped article 2 faces the upstream side in the transport direction of the strip-shaped film 8, the magnetic body 3 of the rod-shaped article 2 is not attracted to the magnet 56, and the position of the rod-shaped article 2 with respect to the strip-shaped film 8 is There may be a relative shift. In that case, the bar-shaped article 2 in the opposite direction can be detected as a foreign object by the foreign object detection unit 90. That is, it can be positively detected that the rod-shaped article 2 is in the reverse direction.

11. Modifications As described above, the mode for carrying out the present invention has been described. However, the above embodiment is for facilitating the understanding of the present invention, and is intended to limit the present invention to the above embodiment. is not. Further, the above embodiments may be changed or improved without departing from the spirit of the present invention, and the present invention includes equivalents thereof. Several changes from the above embodiment will be described below, but some changes described below may be combined as much as possible.

(1) In the above embodiment, a part of the belt-like film 8 is transported in the horizontal direction by the lower film transporter 10, but the whole strip-shaped film 8 may be transported in the horizontal direction by the lower film transporter 10.

(2) In the above embodiment, the rod-shaped article 2 is sandwiched between the band-shaped film 8 and the band-shaped film 9 and wrapped by the band-shaped films 8 and 9. On the other hand, the rod-shaped article 2 may be packaged only by the band-shaped film 8. In this case, instead of the side sealer 70, a bag making device and a sealer are provided between the transport table 40 and the end sealer 80. Specifically, the bag making device is disposed on the downstream side of the transport table 40, and the belt-like film 8 is bent by the bag making device, so that the belt-like film 8 is rounded into a cylindrical shape so as to wrap the rod-like article 2. A sealer is provided on the downstream side of the bag making machine, and the overlapped portions of both sides of the rolled strip film 8 are sealed (heated and pressed) by the sealer.

(3) If the rod-shaped article 2 is an article provided with a magnetic body at one end thereof, other than the ballpoint pen refill (for example, a ballpoint pen refill having a ballpoint pen tip of a magnetic body at a tip portion is a non-magnetic body shaft. A ballpoint pen housed in a cylinder, a mechanical pencil having a core feeding mechanism, which is a magnetic body, or the like built into the end of a non-magnetic body cylinder may be used.

(4) In the said embodiment, although the magnet 56 was a permanent magnet, you may change this to an electromagnet.

(5) The auxiliary transporter 50 may be changed to an auxiliary transporter 150 as shown in FIG. The auxiliary transport machine 150 includes a drive motor 151, a rotor 152, and a magnet 156. The disk-shaped rotor 152 is rotatably provided below the transport table 40. The rotating shaft of the rotor 152 extends in the width direction (direction perpendicular to the paper surface of FIG. 4) just below the downstream edge of the discharge port 21 of the hopper 20. A magnet 156 is attached to the outer peripheral surface of the rotor 152. The number of magnets 156 attached to the outer peripheral surface of the rotor 152 is one or more. When there are a plurality of magnets 156, these magnets 156 are arranged in the circumferential direction of the rotor 152 at a predetermined interval. A drive motor 151 is connected to the rotation shaft of the rotor 152, and the rotor 152 is rotationally driven by the drive motor 151, whereby the magnet 156 rotates around the rotation shaft of the rotor 152. The uppermost point of the circular orbit of the magnet 156 is located in the slit 42. Further, the uppermost point is the proximity portion closest to the strip film 8 in the circular orbit of the magnet 156.

  The direction and speed of rotation of the drive motor 151 are controlled by the control unit 95 so that the direction and speed at which the magnet 156 passes the uppermost point are the same as the direction and speed of conveyance of the strip film 8. When the concave portion 32 of the supply drum 31 passes the lower end of the guide 38 in the circumferential direction, the magnet 156 passes the uppermost point of the circular orbit in the circumferential direction, and the magnetic body 3 of the rod-shaped article 2 that has fallen from the concave portion 32 is reversed. If it is not oriented, it is attracted to the magnet 156, and if it is reversed, it is not attracted to the magnet 156.
