[0010]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 schematically shows a series of packaging processes performed by the turret type packaging apparatus of the present invention. The packaging apparatus includes a film reel RF as a packaging material roll, and the heat-weldable film F is drawn out from the film reel RF along a predetermined path as the film reel RF rotates. At the end of the drawing path of the film F, a feeding path 2 extending vertically is connected.
[0011]
  A tape reel RT is disposed above the feeding path 2 and a tier tape drawn from the tape reel RT.T tIs connected to the film F at the upper end of the feeding path 2.
  Although not shown in FIG. 1, a cutter unit is disposed in the middle of the feeding path 2, and a film gripper is disposed on the feeding path 2. The film gripper reciprocates on the feeding path 2 and rises to the cutter unit to grip the lower end of the film. Thereafter, the film F is fed along the feeding path 2 as the film descends. Along with this feeding, the film F has a tear tape.T tWill be pasted continuously. When the film gripper is lowered to the predetermined lower limit position, the cutter unit is at this time the film F and the tear tape.T tA cut sheet S with a tear tape having a predetermined length is formed as a packaging material.
[0012]
A supply position PS is defined on the feeding path 2, that is, one side of the cut sheet S, and the products A are sequentially supplied to the supply position PS. More specifically, a supply line LS for the product A is arranged below the supply position PS. The supply line LS extends horizontally toward the feeding path 2 and continuously conveys the product A toward the end thereof. To do. Although not shown in FIG. 1, the end of the supply line LS is configured as an elevator. When the elevator is at the same level as the supply line LS, the elevator can receive one product A from the supply line LS and then ascend and supply the received product A to the supply position PS.
[0013]
On the other hand, a turret is arranged on the opposite side of the supply position PS across the feeding path 2. In FIG. 1, only the rotation axis O of the turret is shown, but the turret is provided with a plurality of pockets at equal intervals on the outer periphery thereof. Each pocket has a size capable of receiving the product A, and is sequentially positioned at the receiving position PIN with the intermittent rotation of the turret. Receiving position P_INIs defined at the same level as the supply position PS across the feeding path 2.
[0014]
Further, as viewed in the supply direction of the product A on the supply line LS, the pusher 4 stands by behind the supply position PS, and the pusher 4 passes from the standby position through the supply position PS and the feeding path 2 to the receiving position. P_INCan be reciprocated along the indentation path. Therefore, as is apparent from FIG._INThe pusher 4 moves the product A at the supply position PS together with the cut sheet S to the receiving position P._INExtruding towards the receiving position P_INPush it into one pocket of the turret. In this process, the cut sheet S is folded around the product A.
[0015]
Thereafter, the product A in the pocket and the cut sheet S which is folded down are moved in the circumferential direction along with the intermittent rotation of the turret. In this process, the cut sheet S is formed as a body flap which will be described later, as is apparent from FIG. Folding / body seal, left and right ear folds, left and right side flap folds, and left and right side heat seals are sequentially received and sequentially sealed to wrap product A completely. As a result, packaged product H is obtained. . After this, the package H is the turret discharge position P._OUTThen, it is discharged from the pocket.
[0016]
Referring to FIG. 2, the turret 6 is shown, and the product A is supplied to the supply position Ps by the elevator 8.
The turret 6 has a pair of left and right side disks 10, and these side disks 10 are attached to the hub 12 at a predetermined interval. The hub 12 is supported by a rotating shaft 14, and the rotating shaft 14 is connected to an intermittent drive unit (not shown). Therefore, the hub 12, that is, the turret 6 is intermittently rotated by the rotation of the intermittent drive unit.
[0017]
A plurality of, for example, twelve bracket pieces 16 project radially from the outer periphery of each side disk 10, and these bracket pieces 16 are arranged at equal intervals in the circumferential direction of the side disk 10. The bracket pieces 16 of the side disks 10 are aligned with each other in the circumferential direction to form a pair, and the pair of bracket pieces 16 constitute a mounting bracket for one pocket.
[0018]
Each mounting bracket is provided with a pocket 18, so that the turret 6 has a total of 12 pockets 18. Each pocket 18 is composed of two blade members, these blade members are spaced apart in the circumferential direction of the side disk 10 and can receive the product A together with the cut sheet S therein.
Since there are twelve pockets 18, the turret 6 rotates intermittently by 30 °. As a result, each pocket 18 has a receiving position P._INAnd discharge position P_OUTWhile receiving position P_INTo first to fifth intermediate rotation angle positions P₁~ P_FiveThrough the discharge position P_OUTTo.
[0019]
When the turret 6 is in the state shown in FIG._INThe empty pocket 18 is positioned on the other hand, while the discharge position P_OUTIs positioned with a pocket 18 containing the completed package H. From this state, the supply position P_INWhen the product A is pushed together with the cut sheet S into the empty pocket 18 by the pusher 4, the cut sheet S is folded around the product A as described above, and the cut sheet S is partially pocketed. 18, that is, protrudes from the end surface and both side surfaces of the product A, respectively. In addition, the site | part of the cut sheet S which protruded from the end surface of the product A becomes an upper and lower body flap. On the other hand, at the same time when the product A is pushed into the pocket 18, the discharge position P_OUTThe packaged product H is discharged from the pocket 18 located at. This discharge is performed by a discharge pusher 20 indicated by a two-dot chain line in FIG.
[0020]
Second intermediate rotation angle position P described above₂A barrel flap folding / body sealing unit 22 is disposed outside the turret 6. The body flap folding / body sealing unit 22 includes a folding block 24 and a folding heater block 26. The folding block 24 is positioned upstream of the folding heater block 26 as viewed in the rotational direction of the turret 6, while the folding heater block 26 includes a heater 28.
[0021]
Folding block 24 is arrow B₁As shown by the first intermediate rotation angle position P₁Second intermediate rotation angle position P from the side₂Can be reciprocally swung to the pocket 18. The folding heater block 26 is indicated by an arrow B₂As shown by the third intermediate rotation angle position P_ThreeSecond intermediate rotation angle position P from the side₂It is possible to swing reciprocally up to the pocket 18 in the center.
Now, the second intermediate rotation angle position P₂When the product A is stored together with the cut sheet S which is folded in the pocket 18, the folding block 24 is moved to the second intermediate rotation angle position P.₂The one side flap DF in the cut sheet S is folded on the end surface of the product A at the lower end edge thereof. On the other hand, the folding heater block 26 starts to move behind the folding block 24, and immediately after the folding block 24 starts to move backward, reaches the end surface of the product A, while folding the other body flap DF. Is overlapped with one of the already-folded body flaps DF.
[0022]
At this time, the folding heater block 26 is indicated by an arrow B in the figure._ThreeIn this state, the end face of the product A is pressed, and in this state, the body flaps DF are mutually heat-sealed, that is, body-sealed, and then moved backward. When the body flap DF is thus sealed, the cut sheet S has a cylindrical shape surrounding the product A, and both side portions thereof form tubular portions protruding from both side surfaces of the product A. Has a pair of short and long sides.
[0023]
The folding block 24 and the folding heater block 26 described above are connected to a driving source via a power transmission path including a cam and a link, and are supplied with power from the driving source and are swung at a predetermined timing. The In the figure, the power transmission path and the drive source are not shown.
Third intermediate rotation angle position P_ThreeIn FIG. 2, a pair of folded ear claws 28 are arranged on the left and right sides of the turret 6, and FIG. 2 shows only the pair of folded ear claws 28 on one side. The pair of ear fold claws 28 has the pocket 18 at the third intermediate rotation angle position P._ThreeWhen the pocket 18 is in the vertical direction, the pocket 18 is spaced apart in the vertical direction and can be reciprocated in the direction of contacting and separating from each other as indicated by an arrow C.
[0024]
Now, the turret 6 is intermittently rotated, and the second intermediate rotation angle position P is thus far.₂Is located at the third intermediate rotation angle position P._ThreeThe cylindrical cut sheet S in the product A in the pocket 18 is positioned between the pair of ear fold claws 28 on the side corresponding to the tubular portions on both sides thereof. In this state, each pair of the ear fold claws 28 is moved in a direction approaching each other, and the upper and lower short sides of the tubular portion, that is, the upper and lower ears are folded into the side surfaces of the product A, respectively. This folding forms a pair of side flaps on the cylindrical cut sheet S on both sides of the product A. Thereafter, each pair of the ear fold claws 28 moves backward in a direction away from each other.
[0025]
Each pair of ear folding claws 28 is also connected to the drive source via a power transmission path (not shown) including cams and links, and reciprocates linearly at a predetermined timing in conjunction with each other.
On the other hand, the third intermediate rotation angle position P_ThreeIs provided with a pair of side folding members 30, which are arranged on both sides of the turret 6. FIG. 2 shows only the side folding member 30 on one side.
[0026]
Each side folding member 30 is provided so as to be able to reciprocate in a horizontal plane. Now, each side folding member 30 moves from the illustrated rest position to the third intermediate rotation angle position P._ThreeOf the pair of side flaps on the corresponding side, the rear side flap is folded into the side surface of the product A when viewed in the intermittent rotation direction of the turret 6, Then return to the rest position.
[0027]
The detailed configuration and movement of the side folding member 30 will be described later together with the movement of the ear fold claw 28.
Plate-like side folding guides 32 are fixedly arranged on both sides of the turret 6, and these side folding guides 32 are arranged at the third intermediate rotation angle position P._ThreeFrom the pocket 18 at the discharge position P_OUTIt extends in the circumferential direction of the turret 6 up to the pocket 18 at the center. Accordingly, the side folding guide 32 has the fourth and fifth intermediate rotation angle positions P described above._Four, P_FiveThe pocket 18 is covered from the side.
[0028]
As described above, after the folding of one side flap is completed, when the turret 6 is intermittently rotated next, the third intermediate rotation angle position P_ThreePocket 18 located in the fourth intermediate rotation angle position P_FourMove to. At this time, when the pocket 18 enters between the left and right side fold guides 32, each side fold guide 32 folds the other side flap on the corresponding side at its edge, and the one side flap already in the folded state is folded. Superimpose.
[0029]
Each side folding guide 32 has a fourth and fifth intermediate rotation angle position P._Four, P_FiveHave openings 34, 36 respectively, which are the fourth and fifth intermediate rotational angle positions P._Four, P_FiveThe pocket 18 is exposed from the side folding guide 32. Side heat sealers 38 and 40 are arranged in the openings 34 and 36, respectively, and these side heat sealers 38 and 40 can be brought into contact with and separated from the pocket 18 at the intermediate rotation angle position through the corresponding openings. Therefore, with the intermittent rotation of the turret 6, the third intermediate rotation angle position P_ThreePocket 18 located in the fourth and fifth intermediate rotation angle position P_Four, P_FiveThe side heat sealers 38 and 40 contact the side flaps and heat-seal, that is, side-seal them, so that the package H is obtained.
[0030]
After this, the pocket 18 containing the packaged product H is at the discharge position P._OUTAs described above, the packaging product H is ejected from the pocket 18 by the ejection pusher 20 and the series of packaging processes is completed. The packaged product H discharged from the turret 6 is collected by a conveyor (not shown).
Referring to FIG. 3, the upper ear claw 28 and the side folding member 30 on one side when viewed from the left and right are shown together with the side folding guide 32.
[0031]
The ear fold claw 28 is attached to a mounting plate 42, and this mounting plate 42 is guided by a guide rail 44 extending in the vertical direction and can be moved up and down. The guide rail 44 is attached to the frame 46.
FIG. 3 shows a state in which the ear fold claw 28 folds the ears of the cylindrical cut sheet S described above, whereby a pair of side flaps SF are formed on both sides of the product A, respectively.
[0032]
  Bright from Figure 3EtThe side folding member 30 is made of a plate, and its tip is bent slightly over 90 ° toward the side surface of the turret 6, and this bent portion forms a folding blade 48 for the side flap SF. . The folding blade 48 extends in the vertical direction by the length of the product A.
  The base end portion of the side folding member 30 is attached to a rotation lever 50, and the rotation lever 50 has a rotation shaft 52 at one end portion thereof, and is rotatable in a horizontal plane around the rotation shaft 52. is there. An angle lever 54 is disposed below the rotation lever 50, and a rotation shaft 52 is attached to one end of the angle lever 54. The angle lever 54 is attached to a support shaft 56 at a central bent portion thereof, and is rotatable in a horizontal plane around the support shaft 56. The support shaft 56 is attached to the frame 46 described above. Therefore, the rotation lever 50 is supported by the frame 46 via the angle lever 54 and the support shaft 56.
[0033]
The other end of the angle lever 54 is connected to an air cylinder, and can be rotated around a support shaft 56 by expansion and contraction of the air cylinder. Now, when the angle lever 54 is rotated counterclockwise from the illustrated state, the rotation lever 50 is also rotated in the same direction. As a result, the rotation shaft 52 is deviated from the advance position indicated by the solid line to the retract position indicated by the two-dot chain line, and is separated from the pocket 18 side of the turret 6.
[0034]
In FIG. 3, when the rotation lever 50 is rotated clockwise about the rotation shaft 52 at the forward movement position, the side folding member 30 is moved to the third intermediate rotation angle position P._ThreeRotate clockwise toward the pocket 18 in the pocket, that is, the product A in the pocket 18. At this time, the rotation path of the folding blade 48 in the side folding member 30, that is, the access path X is in contact with the side surface of the product A. Here, the access path X indicates the turning trajectory of the tip of the folding blade 48.
[0035]
Thereafter, when the turning lever 50 is turned counterclockwise about the turning shaft 52 in a state where the turning shaft 52 of the turning lever 50 is deviated to the retracted position, the side folding member 30 is moved. The folding blade 48 is moved along a revolving path Y that is moved to the side of the turret 6 from the access path X, that is, a retreat path Y indicated by a two-dot chain line in FIG. Here, the interval Z between the starting end of the retreat path Y and the end of the access path X is set to be wider than the protruding length of the tubular portion T in the tubular cut sheet S described above.
[0036]
  One end of a link rod is connected to the other end of the rotating lever 50, and the other end of the link rod is connected to the drive source via a power transmission path (not shown) including a cam. Therefore, the link rod reciprocates at a predetermined timing in response to the driving force from the driving source, and the side folding is performed via the rotating lever 50.IncludedThe member 30 is reciprocally rotated. Here, as described above, the rotation lever 50 has its rotation shaft (rotation center) 52 displaced by the rotation of the angle lever 54, so that the other end of the link rod 58 is connected as shown in FIG. In order to allow the deflection of the rotation lever 50, the rotation lever 50 is rotatably supported on the upstream side of the power transmission path.
[0037]
  FIG. 5 shows the third rotation angle position P.₃Shows the state immediately after the pocket 18, that is, the product A is positioned. At this time, the upper and lower ear folding claws 28 and the side folding member 30 are both in the rest position, and the side folding member 30 has the pivot shaft 52 of the pivot lever 50 in the retracted position as shown in FIG. It is positioned.
  From this state, when the angle lever 54 is turned, the turning shaft 52 of the turning lever 50 is deviated from the retracted position to the advanced position as shown in FIG. Then, the ear folding is started as shown in FIG. At this time, the side folding member 30 also starts to move forward, and the folding blade 48 enters the access path X.AlongMove toward product A.
[0038]
As shown in FIG. 9, even when the ear folding by the ear folding claw 28 is completed, the side folding member 30 is in the forward movement process, and thereafter, when the ear folding claw 28 moves backward toward the resting position, FIG. As shown in FIG. 10, the folding blade 48 of the side folding member 30 reaches the side surface of the product A and starts folding the one side flap SF described above. At this time, the tip of the folding blade 48 partially overlaps the tip of the ear fold claw 28. However, at this time, there is an ear fold between the tip of the folding plate 48 and the side surface of the product A. A gap that allows the claw 28 to move backward is secured, and these tips do not interfere with each other.
[0039]
Thereafter, when the folding of one side flap SF is completed as shown in FIGS. 10 and 11, and when the ear fold claw 28 is separated from the product A as shown in FIG. 12, as shown in FIG. The turret 6 is intermittently rotated. Therefore, the third rotation angle position P_ThreePocket 18 is in the fourth rotational angle position P together with product A._FourAt this time, the other side flap SF is folded by the side folding guide 32 as described above.
[0040]
  When the turret 6 starts to rotate and the side flap SF is folded, the rotation lever 50 of the side folding member 30 receives the rotation of the angle lever 54 and the rotation shaft 52 moves from the forward position to the reverse position. Is biased tothisAs a result, the side folding member 30,In other words, the folding blade 48 is in a state of escaping so as to secure a predetermined distance from the side surface of the product A as indicated by a two-dot chain line in FIG.
[0041]
On the other hand, the intermittent rotation of the turret 6 causes the next pocket 18 to move to the third rotation angle position P as shown in FIG._ThreeAt this time, the cylindrical cut sheet S enclosing the product A in the pocket 18, that is, the tubular portion T, does not interfere with the folding blade 48 of the side folding member 30, and The folding blade 48 does not interfere with the tubular portion T even when the side folding member 30 moves backward along the retracting path Y toward the rest position. Therefore, there is no adverse effect on the subsequent ear folding or side flap folding. 3 and 14 is the distance between the inner ends of the pockets 18 in the radial direction of the turret 6 (see FIG. 2).
[0042]
Thereafter, the ear fold claw 28 and the side folding member 30 return to the rest position, and the above-described operation is repeated, so that the third rotation angle position P_ThreeThen, the ear folding and side flap folding are performed in the same manner.
As described above, when the side folding member 30 moves backward, the folding blade 48 moves not along the access path X but along the retracting path Y. Therefore, even if the pitch between the pockets 18 in the turret 6 is shortened, the folding blade Interference between 48 and the tubular portion T of the cut sheet S can be reliably avoided.
[0043]
If the pitch between the pockets 18 can be shortened in this way, the turret 6, that is, the entire packaging device can be reduced in size. Conversely, when the diameter of the turret 6 is the same, the number of pockets can be increased.
Moreover, since the size reduction of the turret 6 contributes also to the weight reduction, replacement | exchange of the turret 6 can be performed easily.
[0044]
Furthermore, since all of the configurations for performing the folding and sealing of the cut sheet S are all arranged in the upper half of the turret 6, an open space can be secured below the turret 6, and therefore this opening The turret 6 can be exchanged using the space.
Furthermore, since a series of packaging processes of the product A by the cut sheet S are all completed in the turret 6, it is not necessary to separately provide a product transfer path for folding or sealing outside the turret 6. Therefore, the mechanism of the entire packaging apparatus is simplified, the installation space is further reduced, and an inexpensive packaging apparatus can be provided.
[0045]
The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, in one embodiment, the side folding member 30 is reciprocally rotated along the access path and the retracting path. Instead, a so-called block motion may be applied to the side folding member 30. .
[0046]
【The invention's effect】
As described above, according to the turret type packaging apparatus of the present invention (Claim 1), since a series of packaging processes for products is completed in the turret, a part of the packaging process is performed outside the turret. There is no need to provide a separate product transfer route. Therefore, not only can the mechanism of the entire packaging apparatus be simplified, but also the downsizing and the installation space can be reduced.
[0047]
  The folding member of the side flap folding means is,For products in the pocketWhile moving forward along the access route on the turret side, Reciprocating along the retreat path that is separated from the access path to the side of the turretIn addition, a gap wider than the protruding length of the tubular portion of the packaging material is ensured between the end of the access path and the start of the retreat path (Claim 2).Even if the pitch between the pockets in the turret is shortened, the folding member interferes with the product packaging during intermittent rotation of the turret.ofCan definitely be avoided. As a result, since the pitch between the pockets can be shortened, the diameter of the turret can be shortened, that is, the packaging apparatus as a whole can be further reduced in size.
[0048]
  A series of packaging processes for the product is completed as the product in the pocket is transported through the upper half of the turret.(Claim 3)An open space can be secured under the turret, and the turret can be easily replaced using this open space.
