Description

The present invention relates to a box packing machine that packs attachments such as product manuals into a cylindrical box together with the product.

Conventionally, packing machines have been proposed that pack items into a folded, flat box in a cylindrical shape, with accompanying documents (attachments) such as instructions on how to use the item packed together with the item (for example, Patent Document 1). The packing machine of Patent Document 1 is configured to place the accompanying documents in front of one opening of the cylindrical box, and push the item into the box by pressing the item toward the accompanying documents with a pusher, thereby packing the accompanying documents, which are wrapped around the outer periphery of the item in a U-shape, into the box together with the item.

Japanese Patent Application Publication No. 4-267722

In the box packing machine disclosed in Patent Document 1, when the pusher pushes the article and the attached documents together through the opening of the cylindrical box, friction and contact resistance between the inner surface of the box and the attached documents cause the attached documents to shift position relative to the article and not bend into a U-shape. In particular, when the attached documents are long, the positions of both ends of the attached documents can shift significantly in the pushing direction, leaving one end protruding outside the box, which can cause problems with the sealing process.

The present invention aims to provide a box packing machine that can pack attachments into a box together with the item while properly folding the attachments.

The packing machine of the invention according to claim 1 of the present application comprises:
A box packing machine packs articles (12) conveyed by an article conveying means (13) into a cylindrical box (10) conveyed by a box conveying means (11),
a support means (40) for supporting the attachment (14) in an upright position such that the middle of the attachment (14) in the longitudinal direction is located between the article (12) and one of the openings (16a) of the box (10);
a pusher (45) for pushing the article (12) together with the attachment (14) supported by the support means (40) between the article (12) and one of the openings (16a) of the box body (10) toward the one of the openings (16a) of the box body (10);
a receiving member (46) which penetrates the box (10) from the other opening side and protrudes from one of the openings before the attachment (14) is pushed by the pusher (45) , and which is positioned in a receiving position facing the attachment (14) supported by the support means (40) at a distance from the attachment (14) so as to be able to clamp the article (12) and the attachment (14) to be pushed by the pusher (45) between the pusher (45),
The support means (40) has a recess (41a) that expands toward the front and rear in the article pushing direction by the pusher (45) as it moves upward to support the lower end of the attachment (14),
With the receiving member (46) positioned at the receiving position, the pusher (45) pushes the item (12) together with the attachment (14) supported by the support means (40), so that the attachment (14) with its lower end supported in the recess of the support means (40) and the item (12) are clamped between the receiving member (46) and the pusher (45) outside the box body (10), and the pusher (45) and receiving member (46) holding the item (12) and attachment (14) are moved to pack the clamped item (12) and attachment (14) into the box body (10) through one of the openings.
According to the invention of claim 1, since the article and the attachment are sandwiched between the pusher and the receiving member and packed into the box, the attachment can be packed into the box without being displaced relative to the article and with the attachment properly wrapped around it. In other words, it is possible to prevent the end of the attachment from protruding outside the box due to the attachment being displaced relative to the article, and to prevent the sealing work from being hindered. In addition, since the receiving member is configured to wait at a position protruding from one opening of the box, it is possible to prevent the attachment from being displaced before the article and the attachment pushed by the pusher are packed into the box.
In addition, by supporting the lower end of the attachment with a recess that expands in front and behind the direction in which the pusher pushes the item as it moves upward, when the attachment is pushed by the item, the lower end of the attachment is prevented from smoothly coming out of the recess and moving along with the item and becoming misaligned.

In the invention according to claim 2 , the pusher (45) is characterized in that an escape portion (45a) is formed on the article pushing surface capable of receiving a seal portion (12a) extending from a storage portion (12b) of the packaged article in the bagged article (12).
According to the second aspect of the present invention, the sealed portion of the article can be accommodated in the recess of the pusher, and the article can be pushed appropriately by the pusher.

In the invention of claim 3 , the support means (40) is characterized in that a guide portion (43) for guiding the article (12) and attachment (14) pushed by the pusher (45) is configured to move to a position where an end portion of the guide portion (43) on the box body (10) faces between a pair of side flaps (19a, 19a) before the article (12) and the attachment (14) enter between a pair of side flaps (19a, 19a) extending from the body portion (16) of the box body (10).
According to the invention of claim 3 , when loading items and attachments, the end of the guide portion can be moved to a position facing between a pair of side flaps on the box body, allowing the items and attachments to be loaded well into the box body without interfering with the side flaps.

According to the present invention, items can be packed into the box with the attachments properly wrapped around the box, and the attachments can be prevented from protruding from the box and interfering with the sealing process.

In addition, a suction portion 46a is provided at the tip of the receiving member 46, and is configured to suction the attached document 14 with the suction portion 46a when the article is stuffed into the carton 10.

6, in the feed device 22, the lower clamping sections 24 (eight in this embodiment) that move between the item stuffing work section S3 and the flap temporary folding work section S4 are provided with first folding members 49 that fold the side flaps 19a, 19a of the carton 10 in which the items 12 and attached documents 14 have been stuffed in the item stuffing work section S3 toward the opening side. The first folding members 49 are provided on each of the opposing clamping members 24a, 24a in the lower clamping sections 24 and are configured to move integrally with the clamping members 24a, 24a. As shown in FIG. 6(a), the first folding member 49 has a pair of folding portions 49a, 49a that can abut the side flaps 19a, 19a extending from both longitudinal ends (opening sides) of the side panel 19 of the carton 10, spaced apart in the longitudinal direction of the body 16. When the pair of clamping members 24a, 24a approach each other to clamp the body 16 of the carton 10 in the width direction, the pair of first folding members 49, 49 approach each other and fold the corresponding side flaps 19a toward the opening side with each folding portion 49a. That is, in the cartoner of the embodiment, the four side flaps 19a extending from both the left and right openings 16a, 16b of the body 16 of the carton 10 are folded at once.

6, in the feed device 22, the lower clamping sections 24 of the plurality (four in the embodiment) that move between the flap provisional folding section S4 and the sealing section S5 are provided with second folding members 50 that re-fold the side flaps 19a, 19a provisionally folded by the first folding members 49, 49 toward the opening side. The second folding members 50 are provided on the opposing clamping members 24a, 24a in the lower clamping sections 24 in the same manner as the first folding members 49, and are configured to move integrally with the clamping members 24a, 24a. As shown in Figure 6(b), the second folding member 50 has a pair of folding portions 50a, 50a spaced apart in the longitudinal direction of the body 16 and capable of abutting the side flaps 19a, 19a extending from both longitudinal ends (opening edges) of the side panel 19 of the carton 10. When the pair of clamping members 24a, 24a approach each other to clamp the body 16 of the carton 10 in the width direction, the pair of second folding members 50, 50 approach each other and use each folding portion 50a to fold the corresponding side flap 19a toward the opening side. That is, in the cartoner of the embodiment, the four side flaps 19a extending from both the left and right openings 16a, 16b of the body 16 of the carton 10 are folded twice: when the carton 10 is transported from the item stuffing work section S3 to the flap pre-folding work section S4, and when the carton 10 is transported from the flap pre-folding work section S4 to the sealing work section S5. Also, as shown in FIG. 17, each folding section 50a of the second folding member 50 has a guide surface 50b formed on the surface facing the outside of the box conveying means 11 in the left-right direction, which is inclined so as to move away from the box conveying means 11 as it goes from bottom to top.

As shown in Figures 14 and 15, in correspondence with the sealing work section S5, a folding device 51 is provided which folds the lid flap 20 of the carton 10 toward the openings 16a, 16b and inserts the glue flap 20a provided on the lid flap 20 into the body 16, and a gluing means 52 is provided which applies glue to the surface of the glue flap 20a. The folding device 51 and the gluing means 52 are provided on both sides of the box conveying means 11 in the left and right directions, and are configured to simultaneously fold the left and right lid flaps 20, 20 extending from the body 16 of the carton 10 positioned in the sealing work section S5 and held by the holding device 30, and to insert the glue flap 20a into the inner surface of the body 16 for gluing.

14 and 15, the folding device 51 is provided with four folding members 54 extending toward the box conveying means 11 side on a base member 53 extending along the carton conveying direction, spaced apart in the carton conveying direction so as to correspond to the four cartons 10 located in the sealing work section S5. The folding members 54 are formed to extend in a bifurcated shape spaced apart in the carton conveying direction, and a space is formed between the pair of extending portions to allow the application of the glue sprayed from the gluing means 52 to the glue margin flap 20a. In addition, the base member 53 is provided with a pusher member 56 that moves back and forth in the left and right direction by an air cylinder 55 at a lower position corresponding to each folding member 54. The folding device 51 is provided with a lateral movement mechanism 57 that moves the base member 53 in the left and right direction, and a lifting mechanism 58 that moves the base member 53 in the up and down direction. A linear operating mechanism that servo-controls an electric actuator is adopted for both the lateral movement mechanism 57 and the lifting mechanism 58. The lifting mechanism 58 is configured to move the base member 53 in the vertical direction to position the folding member 54 at a lower standby position (FIG. 17(a)) where the folding member 54 does not interfere with the lid flap 20 of the carton 10 transported by the feed device 22, and at a folding position (FIG. 17(b)) where the folding member 54 folds the lid flap 20 upward to a position along the guide surface 50b of the folding portion 50a of the second folding member 50. In the folding position, the folding member 54 is set to be located outside the glue flap 20a extending obliquely upward from the folding portion 50a. The lateral movement mechanism 57 is configured to position the folding member 54 at a retreated position (FIGS. 17(a) and (b)) where it can abut against the lid flap 20 when it rises from the standby position to the folding position, and at an advanced position (FIGS. 17(c) and (d)) where the folding member 54, which has been raised to the folding position, folds the glue flap 20a from the crease 20b so that it is approximately horizontal and can enter the openings 16a and 16b of the body 16 of the carton 10. The lower surface of the folding member 54 positioned at the advanced position at the height of the folding position is set to a position where it can guide the insertion of the glue flap 20a into the openings 16a and 16b of the body 16 of the carton 10.

When the folding member 54 is moved to the forward position, the pushing member 56 is moved forward by the air cylinder 55 to fold the lid flap 20 toward the openings 16a, 16b of the body 16 of the carton 10 and insert the glue flap 20a into the body 16 (see Figs. 17(c) and (d)). The gluing means 52 is provided above the folding device 51 and is configured to spray glue onto the upwardly facing surface of the glue flap 20a until the glue flap 20a folded approximately horizontally by the folding member 54 is inserted into the body 16 by the forward movement of the pushing member 56.

The discharge section S6 is provided with a discharge means (not shown) for discharging the sealed cartons 10, and the discharge means is configured to discharge the four cartons 10 that have been transported by the feed device 22 to the discharge section S6 and released from the clamping portion 24 of the feed device 22 to the next process at once.

Next, we will explain the operation of the cartoner in this embodiment.

As shown in Fig. 1, when four cartons 10 are erected into a cylindrical shape by the carton supply device and placed on the placement section 21 of the carton supply work section S1 of the box conveying means 11, the alignment device 23 moves a pair of alignment members 23a, 23a from a separated position toward each other to abut against the lid flaps 20, 20 of the cartons 10, thereby positioning the cartons 10 in an appropriate position where the longitudinal center of the body 16 is aligned with the left-right center of the placement section 21. The feed device 22 raises the transfer section group, which is located in the retreated position in the retracted position, to the clamping position by the lifting means 25, and also moves a pair of clamping members 24a, 24a of each lower clamping section 24 toward each other to clamp the body 16 of each carton 10 on the placement section 21 from both sides in the width direction. Then, the feed device 22 uses the movement mechanism 26 to move the group of transport sections downstream by one work section, so that the four cartons 10 located in the carton supply work section S1 are slid together on the placement section 21 and transported downstream to the flap setting work section S2.

When four cartons 10 are transported to the flap forming work section S2, the holding device 30 lowers the lifting member 33 from the upper standby position to the clamping position by the lifting mechanism 32, and the clamping members 31a, 31a of each upper clamping section 31 approach each other to clamp the body 16 of the carton 10 from both sides in the width direction (see Figure 7). When the carton 10 is clamped by the holding device 30, the feed device 22 releases the clamping of the carton 10 by the lower clamping section 24, and then lowers the transfer section group from the clamping position to the retracted position by the lifting means 25, and moves the transfer section group upstream by one work section distance by the moving mechanism 26.

When a carton 10 is clamped by the upper clamping part 31 of the holding device 30 in the flap forming work section S2, the forming member 38 of the forming means 36 enters between a pair of side flaps 19a, 19a extending from one opening edge of the opening 16a of the carton 10, and the forming member 38 moves back and forth in the carton conveying direction, whereby the pair of side flaps 19a, 19a are bent outwardly so as to be separated from each other and formed. When the next four cartons 10 are placed on the carton supply work section S1 in the loading section 21 by the carton supply device, in the feeding device 22, the transport part group in the retracted position is raised to the clamping position by the lifting means 25, and each carton 10 is clamped by the lower clamping part 24. At this time, when the carton 10, which is located in the flap forming work section S2 and is clamped by the upper clamping section 31 of the holding device 30, is clamped by the lower clamping section 24 of the feeding device 22, the holding device 30 releases the clamping of the carton 10 by the upper clamping section 31, and the lifting mechanism 32 raises the lifting member 33 from the clamping position to the standby position.

As described above, the feed device 22 uses the moving mechanism 26 to move the group of transport parts downstream by one work section, thereby transporting the four cartons 10 located at the carton supply work section S1 to the flap forming work section S2 and the four cartons 10 located at the flap forming work section S2 to the item stuffing work section S3. Then, each carton 10 transported to the flap forming work section S2 and the item stuffing work section S3 is clamped and positioned by the upper clamping section 31 of the holding device 30. After releasing the clamping of the carton 10 by the lower clamping section 24, the feed device 22 lowers the group of transport parts from the clamping position to the evacuation position and moves upstream by one work section. That is, by using the feed device 22 to perform box motion on the group of transport bodies, the four cartons 10 supplied to the carton supply work section S1 are transported in order to the flap forming work section S2 and the item stuffing work section S3, and are held by the holding device 30 in these work sections S2 and S3.

In the item stuffing work section S3, as shown in Figures 10 and 11, each of the four attachments 14 removed from the stacking section by the attachment supply device 39 is supported by each of the support means 40 in an upright position with its longitudinal axis extending vertically. In addition, the four items 12 are transported to the item stuffing work section S3 by the item transport conveyor 13 and stopped intermittently, and each item 12 faces the carton 10 positioned in the item stuffing work section S3, sandwiching the attachment 14 supported by the support means 40 between them.

As shown in Fig. 12, when the carton 10 and the article 12 are transported and positioned in the article loading work section S3, the guide device 61 lowers the guide member 62 from the standby position and positions it at a guide position where it can guide the upper surface of the article 12 supported by each bucket of the article transport conveyor 13. Also, as shown by the two-dot chain line in Fig. 13 and Fig. 16(a), the receiving member 46 is moved from the retreat position to the pick-up position by the forward/backward movement mechanism 48, the receiving member 46 penetrates the inside of the carton 10 and enters the tube portion 43 of the support means 40, and the suction portion 46a provided at the tip is positioned at the pick-up position approaching the attached document 14 supported by the support means 40. Also, the pusher 45 starts to advance from the retreat position by the forward/backward movement mechanism 47, and the article 12 on the article transport conveyor 13 is pushed into the tube portion 43 by the pusher 45 while being guided by the guide member 62 and the side wall of the bucket. When the article 12 pushed into the tube portion 43 by the pusher 45 comes into contact with the attachment 14, the upper support member 42 is moved toward the carton 10 by the air cylinder 44, and the attachment 14 supported by the tube portion 43 of the upper support member 42 moves toward the carton 10 together with the article 12. Then, when the attachment 14 that comes into contact with the article 12 pushed by the pusher 45 is pushed toward the carton 10, the middle portions of the article 12 and the attachment 14 are clamped between the receiving member 46 in the receiving position and the pusher 45, as shown in FIG. 16(b).

When the article 12 and the attached document 14 are clamped between the pusher 45 and the receiving member 46, the receiving member 46 moves in synchronization with the pusher 45 toward the retreated position by the forward/backward movement mechanism 48. When the attached document 14 moves toward the carton 10 together with the article 12 clamped between the pusher 45 and the receiving member 46, as shown in Fig. 16(c), the extension portion extending up and down sandwiching the clamped portion of the attached document 14 is pulled into the tubular portion 43, and is folded to fit along the top and bottom surfaces of the article 12. Then, the article 12 pushed further by the pusher 45 passes through the tubular portion 43 with the attached document 14 wrapped around it, and is pushed into the carton 10 through one opening 16a, as shown in Fig. 16(c). A pair of side flaps 19a, 19a located on the side of the carton 10 where the article 12 is loaded are bent outwardly by the bending means 36 so as to be spaced apart from each other, so that the article 12 and the attached document 14 can be loaded through the opening 16a without any problems. When the pusher 45 advances to the loading position, the pusher 45 is returned to the retracted position by the forward/retract mechanism 47, and the receiving member 46 is returned to the retracted position by the forward/retract mechanism 48, and the clamping of the article 12 and the attached document 14 is released.

When the items 12 and attached documents 14 are stuffed into the body 16 of the carton 10 in the item stuffing work section S3, the feed device 22 box-motions the group of transporting bodies using the lifting means 25 and moving mechanism 26, and transports the carton 10 stuffed with the items 12 and attached documents 14 in the item stuffing work section S3 to the flap pre-folding work section S4, and at the same time, the empty carton 10 whose side flaps 19a, 19a have been creased in the flap creasing work section S2 is transported to the item stuffing work section S3. As shown in FIG. 6(a), in the feeding device 22, the clamping members 24a, 24a of the lower clamping section 24 that clamp the body 16 of the carton 10 between the item stuffing work section S3 and the flap temporary folding work section S4 are provided with first folding members 49, 49. When the body 16 is clamped by the clamping members 24a, 24a, the left and right side flaps 19a, 19a extending from the body 16 are folded toward the opening side by the folding portions 49a, 49a of the first folding members 49, 49.

The carton 10 transported to the flap pre-folding work section S4 by the feed device 22 is handed over from the lower clamping section 24 to the upper clamping section 31 of the holding device 30. Then, by box-motioning the group of transport bodies by the feed device 22, the carton 10 in the flap pre-folding work section S4 is handed over from the upper clamping section 31 to the lower clamping section 24 and transported to the sealing work section S5. As shown in FIG. 6(b), in the feeding device 22, the clamping members 24a, 24a of the lower clamping section 24 that clamp the body 16 of the carton 10 between the flap pre-folding work section S4 and the sealing work section S5 are provided with second folding members 50, 50. When the body 16 is clamped by the clamping members 24a, 24a, the side flaps 19a, 19a extending from the body 16 are folded again toward the opening side by the folding portions 50a, 50a of the second folding members 50, 50.

When the carton 10 is transported to the sealing work section S5, the body 16 is clamped by the upper clamping section 31 of the holding device 30 while the body 16 is clamped by the lower clamping section 24 of the feeder 22. In addition, the suction sections 64a, 64a located between the clamping members 31a, 31a of the upper clamping section 31 corresponding to the sealing work section S5 suction the top panel 18 of the carton 10, and as the suction section 64a is raised by the air cylinder 64b, the top panel 18 is lifted by a predetermined height and the openings 16a, 16b of the body 16 expand upward. As shown in Figures 17(a) and 17(b), the folding device 51 raises the folding member 54 from the standby position to the folding position by the lifting mechanism 58, and the folding member 54 folds each lid flap 20 of the carton 10 obliquely along the guide surfaces 50b, 50b of the folding parts 50a, 50a that fold the side flaps 19a, 19a toward the opening side. In addition, the folding member 54 is moved from the retreated position to the advanced position by the lateral movement mechanism 57, and the glue flap 20a extending obliquely upward from the folding parts 50a, 50a is folded approximately horizontally from the crease 20b as shown in Figure 17(c). In this state, the clamping by the lower clamping part 24 of the feeding device 22 is released, and the folding parts 50a, 50a of the second folding members 50, 50 pass between the side flaps 19a, 19a and the lid flap 20 in the front and rear in the carton conveying direction. In addition, glue is sprayed from the gluing means 52 toward the upward surface of the approximately horizontal glue flap 20a, and glue is applied to the surface of the glue flap 20a that faces the void in the folding member 54.

When the glue is applied to the glue flap 20a, the pushing member 56 advances toward the carton 10 by the air cylinder 55, and the lid flap 20, which has been bent diagonally by the pushing member 56, is folded toward the openings 16a, 16b of the body 16, and the glue flap 20a is guided by the underside of the folding member 54 and inserted into the body 16. At this time, the vicinity of the opening in the top panel 18 of the carton 10 is lifted by the suction part 64a of the holding device 30, and the openings 16a, 16b are widened upward, so that the glue flap 20a can be smoothly inserted into the body 16. After the glue flap 20a is inserted into the body 16, as shown in FIG. 17(d), the suction parts 64a, 64a are lowered by the air cylinder 64b, and the top panel 18 is pressed against the surface (glued surface) of the glue flap 20a inserted into the body 16 to which the glue is attached.

The cartons 10 sealed in the sealing work section S5 are transported to the discharging work section S6 by the box motion of the transport body group caused by the feed device 22, and the cartons 10 in the discharging work section S6 are discharged to the next process by the discharging means.

The cartoner of the embodiment is configured so that the item 12 and the attached document 14 are packed into the carton 10 while being held between the pusher 45 and the receiving member 46. Therefore, even if the attached document 14 is subjected to friction or contact resistance with the carton 10, the attached document 14 can be prevented from shifting position relative to the item 12, and the item 12 can be packed into the carton 10 with the attached document 14 properly wrapped around the item 12. In other words, it is possible to prevent the end of the attached document 14 from protruding outside the carton 10 due to the attached document 14 being shifted position relative to the item 12, and to prevent interference with the sealing operation.

The receiving member 46 is configured to receive the attachment 14 at a position close to the attachment 14 when the article 12 and the attachment 14 are stuffed into the carton 10, so that the attachment 14 can be prevented from shifting position before the article 12 and the attachment 14 pushed by the pusher 45 are stuffed into the carton 10. In addition, the receiving member 46 is configured to enter the carton 10 from the opening 16b opposite to the opening 16a through which the article 12 is stuffed into the carton 10 and to be positioned at the receiving position, so that the receiving member 46 can have a simple configuration that moves forward and backward in the left and right directions, and the configuration can be simplified. The attachment 14 supported by the support means 40 moves toward the carton 10 when the article 12 abuts against the attachment 14, so that the article 12 and the attachment 14 can be clamped between the pusher 45 and the receiving member 46 without shifting position while the attachment 14 is supported by the support means 40. In addition, the support means 40 supports the attachment 14 from below, so that when the attachment 14 is pushed by the item 12, the attachment 14 moves smoothly together with the item 12, preventing it from shifting out of position.

The pusher 45 has an escape portion 45a on the article pushing surface that can receive the end seal portion 12a of the article 12, so that when pushing the article 12, the end seal portion 12a can be accommodated in the escape portion 45a. In other words, when the pusher 45 abuts against the article 12, it prevents the end seal portion 12a from folding over in a biased state against the end surface of the article, which would prevent the pusher 45 from pushing the article 12 in the correct direction, and the article 12 can be pushed properly toward the support means 40 and the carton 10.

In the cartoner of the embodiment, when the carton 10 is transferred between the feeding device 22 and the holding device 30 in the flap forming work section S2, the item stuffing work section S3, the flap temporary folding work section S4 and the sealing work section S5, the carton 10 is clamped by the lower clamping section 24 of the feeding device 22 and then clamped by the upper clamping section 31 of the holding device 30. This allows the carton 10 to be positioned in the correct position in each of the work sections S2, S3, S4 and S5 without being misaligned in the carton conveying direction.

According to the cartoner of the embodiment, the lower clamping section 24, which clamps and transports the carton 10 to the item stuffing section S3, the flap pre-folding section S4, and the sealing section S5 in the feeder 22, is provided with folding members 49, 50 for folding the side flaps 19a, 19a of the carton 10 toward the opening side, so that there is no need to provide a dedicated flap folding means in the sealing section S5, and the mechanical configuration in the sealing section S5 can be simplified. In addition, the second folding member 50 provided in the lower clamping section 24, which clamps and transports the carton 10 to the sealing section S5, is provided with a guide surface 50b, so that the lid flap 20 can be folded in the correct position by the vertical movement of the folding member 54 of the folding device 51. In addition, the second folding member 50 supports the side flaps 19a, 19a on the opening side until the folding member 54 folds the lid flap 20, so that the lid flap 20 can be folded outside the side flaps 19a, 19a.

The sealing section S5 is provided with folding devices 51 for folding the left and right flaps 20, 20 extending from the body 16 of the carton 10 transported to the sealing section S5 toward the opening side, so that the left and right flaps 20, 20 can be folded simultaneously, shortening the operation time. In addition, the sealing section S5 is configured so that when the glue flap 20a is inserted into the body 16 of the carton 10, the top panel 18 is lifted by the suction parts 64a, 64a to widen the openings 16a, 16b, so that the glue flap 20a can be inserted smoothly.

In the cartoner of the embodiment, the box conveying means 11 conveys multiple cartons 10 at once to each of the work sections S2, S3, S5, and S6, and each of the work sections S2, S3, S5, and S6 is configured to be able to work on multiple cartons 10 simultaneously, thereby improving production capacity. In addition, the item stuffing work section S3 and the sealing work section S5 are configured to use servo-controlled mechanisms to perform various operations, so they can easily accommodate changes in the size of the cartons 10 and items 12.
