Description

  The present invention relates to a packaging box reversing and accumulating device, and in particular, a group of folded packaging boxes that are sequentially supplied in a leaning state is reversed or forwardly rotated, and a group of reversed packaging boxes and a group of forwardly rotated states are grouped. The present invention relates to a packaging box reversing and accumulating apparatus that can improve productivity and reduce labor costs by accumulating the packaging boxes.

Conventionally, a box making machine (also referred to as a gluer machine) has been used for manufacturing packaging boxes.
This box making machine usually produces a folded packaging box by punching cardboard or corrugated cardboard, and pasting and folding the punched sheet-like material while moving inside the box making machine. To do. In addition, folded packaging boxes (abbreviated as packaging boxes as appropriate) are overlapped at a pitched pitch in the crimping process of the box making machine, and pushed in a vertical direction in a flat state in order to ensure adhesion. After receiving pressure, it is sequentially carried out.

Further, the post-process of the folded packaging box (including the one-touch case) carried out from the box making machine is usually performed manually by the operator.
That is, in the post-process, the operator visually checks the quality of the carried-out packaging box, picks up defective products, counts a predetermined number of good products, and stacks them. Subsequently, another group of packaging boxes is stacked on the group of stacked packaging boxes in a state where the top and bottom are reversed, and bound. The bundled transport boxes are arranged on a pallet or put in a box to prepare for shipment.

In particular, when the packaging box is a one-touch case, the bottom of the one-touch case is several times thicker than the other parts because it is bonded and folded. Therefore, when packing and shipping the packaging box, in order to make the thickness after binding almost parallel, two groups of packaging boxes need to be overlapped and bound with the top and bottom reversed. In addition, due to the complexity of the packaging box, defective products such as defective adhesion and folding failure may occur, and monitoring by humans is indispensable at the product carry-out section from the box making machine.
In addition, since packaging boxes are widely spread and are produced in large quantities, various techniques have been proposed for a box making machine and its peripheral devices.

  For example, Patent Document 1 discloses a lower belt disposed horizontally from a case receiving side to a discharging side of a machine frame, and a first upper belt provided so as to be able to move up and down in the belt direction toward the lower belt receiving side and to be moved up and down. The second upper belt, which can be moved up and down on the discharge side of the lower belt, constitutes a sandwich-feed type case conveyor device using a parallel split belt, and in the belt direction in the middle region of the first and second upper belts. And a reversing device that can move back and forth along a predetermined number of transfer cases. The reversing device is formed with a hook-like hook at the tip and pivotally mounted on a support shaft. A technique of a case automatic reverse transfer device comprising a plurality of parallel leaf springs is disclosed.

Patent Document 2 discloses that an elevator that collects and discharges sheet-like cardboard that has been processed and discharged by an upstream box making machine and a set number of sheet-like cardboards that are accumulated and counted on the elevator. When the stack is formed and the sheet-like cardboard to be discharged next is partitioned above the stack, the shutter is moved to the position of the lower conveyor by the elevator and conveyed to the lower conveyor. There is disclosed a technology of a sheet-like corrugated cardboard counting / discharging device provided with a presser for pressing the upper surface of the stack, a pusher for sending the stack downstream, and a lower conveyor for transporting the stack to the next process.
In this sheet-like cardboard counting and discharging apparatus, the driving means for moving the shutter forward and backward, the driving means for raising and lowering the shutter, the driving means for moving the presser forward and backward, and the driving means for raising and lowering the presser are independent driving means. Thus, the shutter is retracted while the presser is lowered, or the shutter is raised while the presser is waiting.

Here, preferably, the conveyance direction of the conveyance means 104 is perpendicular to the conveyance direction of the packaging box 11 on the upstream side of the above-described leaning means.
In this way, by changing the transport direction of the packaging box 11 to a right angle, for example, the packaging box 11 is inspected without greatly changing the current space of the product carry-out portion of the existing box making machine (not shown). Work space can be secured. Also, the operator can easily monitor the status of counting and the status of sorting operation while performing work such as inspection.

In the present embodiment, the packaging box 11 is leaned against the support member 142 at an angle of about 60 ° from the horizontal direction.
The belt conveyor 141 is inclined at an angle of about 30 ° from the horizontal direction, and the support member 142 is inclined at an angle of about 60 ° from the horizontal direction so as to be substantially perpendicular to the placement surface of the belt conveyor 141. ing. Further, the guide member 143 in the region corresponding to the sliding member 103 is substantially along the vertical direction, and further, on the upstream side (lower side in FIG. 5B) of the region corresponding to the sliding member 103, the support member 142. (Usually close enough to accommodate one packaging box 11), and away from the support member 142 on the downstream side (the upper side in FIG. 5B) corresponding to the sliding member 103. (Normally, the packaging boxes 11 are separated so that they can be accommodated even when they are overlapped).

  With the configuration described above, the falling packaging box 11 has the bottom of the packaging box 11 substantially in contact with the belt conveyor 141, and the upstream end of the packaging box 11 (the lower side in FIG. 5B) is supported. The member 142 is almost entirely contacted. That is, since the packaging box 11 is inclined in a stable state at an angle of about 60 ° from the horizontal direction and leans against the support member 142, the packaging box 11 can be extended even if the plurality of packaging boxes 11 are conveyed in a stacked state. Compared with the conveying state in the conveying means 102, the weight of the subsequent packaging box 11 due to the overlapping is greatly reduced. Thereby, as will be described later, the reliability of the sorting operation can be improved, and damage or dirt due to contact between the packaging boxes 11 can be suppressed.

  In addition, since the conveying speed of the belt conveyor 141 is normally set to be substantially the same as the conveying speed of the extended conveying means 102, the belt conveyor 141 sequentially conveys the packaging boxes 11 at substantially the pitch P. Furthermore, when the packaging box 11 is in a stable state and is sequentially conveyed at substantially the pitch P, a gap 12 having substantially the same shape is formed between the upstream ends of the packaging box 11. Thereby, as will be described later, the detection accuracy of the counting sensor 105 can be improved, and the certainty of the sorting operation can be improved. Also by these, the reliability of the sorting operation can be improved.

In the present embodiment, the packaging box 11 is inclined at an angle of about 60 ° from the horizontal direction and leans against the support member 142, but the angle of inclination is not limited to the above angle.
Here, it is preferable that the packaging box 11 is tilted at an angle of 45 ° or more and less than 90 ° from the horizontal direction, and more preferably inclined at an angle of 55 ° or more and less than 85 ° from the horizontal direction. It is good to have. In this way, as described above, the reliability of the sorting operation can be improved, and damage or dirt due to contact between the packaging boxes 11 can be suppressed.
Note that the reason for the above numerical limitation is that when the packaging box 11 is inclined at an angle of less than 45 ° from the horizontal direction, even if the plurality of packaging boxes 11 are transported in an overlapping state, the transport in the extended transport means 102 is performed. This is because, compared with the state, the effect that the weight of the subsequent packaging box 11 due to the overlapping can be greatly reduced cannot be exhibited sufficiently. In addition, when the packaging box 11 is vertical, the packaging box 11 may be tilted in one direction, and in an unstable state, the reliability of counting and sorting may not be improved.

(Counting sensor)
The counting sensor 105 is usually an optical sensor or the like, and is attached to the support member 142 on the downstream side (the upper side in FIG. 5B) corresponding to the sliding member 103 and is transported by the transport means 104. The packaging box 11 is detected. The control means to be described later receives a detection signal from the counting sensor 105 and generates detection information of the packaging box 11 when the gap 12 is detected after detecting the end portion. In addition, the detection information of the packaging box 11 means the information regarding the order of the detected packaging box 11, the information regarding the detected time, etc.
Here, in the packaging box 11 to be transported, as described above, the upstream end of the packaging box 11 is substantially entirely in contact with the support member 142, and the packaging box 11 is in a stable state, and substantially By being sequentially conveyed at the pitch P, a gap 12 having substantially the same shape is formed between the upstream ends of the packaging box 11. Therefore, the counting sensor 105 can detect the packaging box 11 reliably and accurately.

The packaging box 11 is divided.

Here, it is preferable that the sorting engagement member 161 has a roller 611 at the tip on the side of the conveying unit 104. In this way, when the roller 611 contacts the guide member 143, the sorting engagement member 161 can move smoothly, and the roller 611 rolls on the surface of the packaging box 11 in contact with the (n + 5) th packaging box 11, so that a problem such as damage to the packaging box 11 can be prevented.
Moreover, since the structure of the sorting means 106 is simplified, for example, the manufacturing cost can be reduced as compared with the case where a robot or the like is used.

In addition, the thickness of the engaging member 161 for classification and the position with respect to the packaging box 11 are set suitably.
In addition, the support member 142 has an opening in a region where the sorting engagement member 161 enters the belt conveyor 141 and retracts from the belt conveyor 141, and the sorting engagement member 161 has no problem. It enters on the belt conveyor 141 and separates a predetermined number of packaging boxes 11 from the upstream packaging box 11.
Further, the support member 142 is formed up to a position corresponding to the downstream end (upper end in FIG. 7A) of the belt conveyor 141, and the guide member 143 is configured such that the sorting engagement member 161 is the belt conveyor. The guide member 143 in this area is along the vertical direction with respect to the belt conveyor 141.
Moreover, the structure of the moving means 162 for sorting mentioned above and the moving means 172 for extrusion mentioned later is an example, and is not limited to this structure.

(Extruding means)
FIG. 7: is the outline of the principal part for demonstrating the extrusion means of the inversion stacking apparatus of the packaging box based on embodiment of this invention, (a) has shown the top view, (b) is an enlarged view. Show.
In FIG. 7, the push-out means 107 is provided on the downstream side (upper side in FIG. 7A) of the region corresponding to the sorting means 106 and engages with the upstream end of the packaging box 11. The moving member 172 for extruding which moves the combined member 171 and the engaging member 171 for extruding is provided.
The push-out means 107 supplies the packaging box 11 sorted by the sorting means 106 so as to push it out to the reversing basket 21 and the normal rotation basket 31.

The pushing moving means 172 of the present embodiment has substantially the same structure as the sorting moving means 162 described above, and has two roller chains 721 and 723 arranged at predetermined positions facing each other. That is, as illustrated in FIG. 7A, a roller chain 721 is provided on the right side of the support member 142, and a roller chain 723 is provided on the right side of the roller chain 721. Each roller chain 721 and 723 is hung on four sprockets 722 and 724, respectively, and has substantially the same shape.
Further, although not shown, the pushing moving means 172 has a motor (stepping motor, servo motor, etc.) that rotates the sprockets 722 and 724 in synchronization.

Further, as shown in FIG. 7B, the pushing moving means 172 includes connecting shafts 725 and 726 respectively attached to predetermined portions of the two roller chains 721 and 723, and a pair of connecting shafts 725 opposed to each other. 726, a moving plate 729 attached via bearing blocks 727, 728, an attaching means for attaching the pushing engagement member 171 to the moving plate 729 so as to be reciprocally movable, and the pushing engagement member 171 for the conveying means 104.

Further, the pushing means 107 aligns the positions of the packaging boxes 11 in the transport direction by moving the sorted packaging boxes 11 in the transport direction at a speed faster than the transport speed of the transport means 104.

In addition, the thickness of the engaging member 171 for extrusion, and the position with respect to the packaging box 11 are set suitably.
Further, the support member 142 has an opening formed in a region from a position where the pushing engagement member 171 enters the belt conveyor 141 to a downstream end (upper end in FIG. 7A). The pushing engagement member 171 enters the belt conveyor 141 without any trouble, and feeds the divided packaging boxes 11, that is, the group of packaging boxes 10, to the reversing basket 21 and the normal rotation basket 31.

(Control means)
The packaging box inversion stacking apparatus 1 usually has a control means, and this control means (not shown) is usually an information processing apparatus such as a computer or a programmable logic controller. Control means 3, stacking means 4, moving means 5 and the like.
Further, the control means inputs a detection signal from the counting sensor 105, counts the packaging box 11 based on the detection signal, controls the sorting means 106 based on the count, and also performs a predetermined step in the next step. The information from the device is input, and the sorting means 106 is controlled based on this information.

Next, the operation of the packaging box inversion stacking apparatus 1 having the above-described configuration will be described with reference to the drawings.
As shown in FIG. 5, when the packaging box 11 is sequentially supplied from a conveyor of a box making machine (not shown), the packaging box inversion stacking apparatus 1 is configured so that the extended conveying means 102 is substantially at a pitch P. It is conveyed downstream (left side in FIG. 5).
Next, the leaning means causes the packaging box 11 to fall through the sliding member 103 to be in a leaned state. At this time, since the presser roller 131 is pressed by the falling packaging box 11 so that the subsequent packaging box 11 does not lift, the packaging box 11 on the extension conveying means 102 is maintained in an aligned state, and is substantially pitch P. Are sequentially transported and then fall sequentially.

Next, the transport unit 104 sequentially transports the dropped packaging box 11 in a state of leaning on the support member 142 and a part of the packaging boxes 11 overlapping each other.
At this time, as described above, the packaging box 11 that is dropped and conveyed has the bottom of the packaging box 11 substantially in contact with the belt conveyor 141, and the upstream end of the packaging box 11 is the support member 142. And in a stable state, is inclined at an angle of about 60 ° from the horizontal direction and leans against the support member 142. Therefore, even if the plurality of packaging boxes 11 are transported in an overlapped state, the weight of the subsequent packaging box 11 due to the overlapping is greatly reduced as compared with the transported state in the extended transporting means 102. Damage or dirt due to contact between the boxes 11 can be suppressed.
Moreover, since the conveyance means 104 has changed the conveyance direction of the packaging box 11 in the extended conveyance means 102 at right angles, for example, the current space of the product carry-out part of the existing box making machine (not shown) is greatly changed. Without this, it is possible to secure a work space for inspecting the packaging box 11 and the like. Also, the operator can easily monitor the status of counting and the status of sorting operation while performing work such as inspection.

Next, the counting sensor 105 detects the packaging box 11 conveyed by the conveying means 104, and the control means inputs a detection signal from the counting sensor 105, and after detecting the end portion, the gap 12 is detected. Is detected, the detection information of the packaging box 11 is generated.
Here, as described above, the upstream end of the packaging box 11 is substantially entirely in contact with the support member 142, and the packaging box 11 is sequentially conveyed in a stable state. As a result, a gap 12 having substantially the same shape is formed between the upstream ends of the packaging box 11. Therefore, the counting sensor 105 can detect the packaging box 11 reliably and accurately.

  Further, the control means, as shown in FIG. 6, is based on the detection information of the packaging box 11 (information on the detected order of the packaging box 11 and information on the detected time, etc.) and the information on the conveyance speed of the belt conveyor 141. Then, the position of the packaging box 11 that has passed through the counting sensor 105 is calculated. Then, based on the detection information, the control means determines that the packaging box 11 corresponding to the predetermined quantity (in this embodiment, the (n + 4) th packaging box 11 (n is a natural number)) The sprockets 622 and 624 are synchronized so that the tip of the sorting engagement member 161 enters the belt conveyor 141 after the tip passes an entry start point (not shown) for starting entry onto the belt conveyor 141. To control the rotating motor.

Next, as shown in FIG. 6, the sorting means 106 has an entry start point (not shown) at which the tip of the n + 4th packaging box 11 starts to enter the belt conveyor 141. After passing, the leading end of the sorting engagement member 161 enters the belt conveyor 141, and a predetermined number (in this embodiment, five) of the packaging boxes 11 is transported at a speed higher than the transport speed of the transport means 104. By moving to, a predetermined number of packaging boxes 11 are separated from the upstream packaging box 11.
At this time, since the weight of the subsequent packaging box 11 due to overlapping is greatly reduced, the reliability of the sorting operation can be improved,
Further, since the partitioning engagement member 161 has the roller 611 at the tip on the side of the conveying unit 104, when the roller 611 contacts the guide member 143, the partitioning engagement member 161 can move smoothly, Further, since the roller 611 rolls on the surface of the packaging box 11 in contact with the packaging box 11, it is possible to prevent problems such as damage to the packaging box 11.

Next, as shown in FIG. 7, the push-out means 107 feeds the packaging boxes 11 sorted by the sorting means 106, that is, the group of packaging boxes 10, to the reverse basket 21 and forward rotation basket 31.
At this time, the pushing means 107 aligns the positions of the packaging boxes 11 in the transport direction by moving the sorted packaging boxes 11 in the transport direction at a speed faster than the transport speed of the transport means 104.

Next, the reversing operation, the normal rotation operation, and the accumulating operation of the packaging box reversing and accumulating device 1 will be described with reference to the drawings.
FIG. 8: has shown the schematic side view of the principal part for demonstrating operation | movement of the inversion stacking apparatus of the packaging box based on embodiment of this invention.
As shown in FIG. 8 (a), the packaging box reversing and accumulating apparatus 1 has a first basket (a reversing basket 21 in which 1 is shown in the circle and illustrated). It moves to the left side of the endless loop and moves to the lower stage and stops, and a group of packaging boxes 10 are supplied by the pushing means 107.
Next, as shown in FIG. 8 (b), the reversing basket 21 and the forward rotation basket 31 are moved by the moving means 5, and the second basket (in the figure, 2 is shown in the square and illustrated). The forward rotation basket 31.) is moved to the left side and the lower stage of the endless loop and stopped, and the group of packaging boxes 10 is supplied by the pushing means 107. The first basket moves to the left side of the endless loop and the middle stage and stops.
As described above, the reversing basket 21 and the forward rotation basket 31 sequentially move to the left side and the lower stage of the endless loop and stop, and the group of packaging boxes 10 is supplied by the pushing means 107.

FIG. 9: has shown the schematic side view of the principal part for demonstrating operation | movement of the inversion stacking apparatus of the packaging box based on embodiment of this invention.
Next, as shown in FIG. 9 (a), the packaging box inversion stacking apparatus 1 moves the inversion basket 21 and the forward rotation basket 31 by the moving means 5, and the first basket moves to the left side of the endless loop. The reversing rotation means 22 rotates the reversing basket 21 in the counterclockwise direction, and the group of packaging boxes 10 is placed on the reversing conveying means 23 in the reversed state. After that, the reversing basket 21 is rotated in the clockwise direction.

Here, the reversing and accumulating apparatus 1 for packaging boxes reverses a group of packaging boxes 10 together, so that the efficiency is greatly improved compared to the case automatic reversing transfer apparatus of Patent Document 1 that reverses the packaging boxes one by one. Can be made.
Further, since the group of packaging boxes 10 in a leaned state can be turned in an inverted state by rotating them by about 90 ° in the counterclockwise direction, the patent can be inverted by rotating the packaging box by about 180 °. Compared with the case automatic reversal transfer device of Document 1, the efficiency can be greatly improved in this respect as well.

  Further, as shown in FIG. 9A, the reversing basket 21 and the forward rotation basket 31 are moved by the moving means 5, and the second basket is moved to the left side and the middle stage of the endless loop and stopped. The forward rotation basket 31 is rotated clockwise by the normal rotation first rotation means 32 at substantially the same timing as the reversing basket 21 is rotated. In addition, the group of packaging boxes 10 that are moved obliquely downward and are supplied are placed on the forward conveying means 34 with the bottom portion supported by the guide member 33 and the glued portion on the upper surface side.

  Next, as shown in FIG. 9 (b), the reversing and accumulating apparatus 1 for packaging boxes moves the reversing basket 21 and the normal rotating basket 31 by the moving means 5, and the first basket moves to the right of the endless loop. When the second basket moves to the left side of the endless loop and stops, the reversing transport means 23 moves the group of packaging boxes 10 placed downstream to the downstream side. The group of packaging boxes 10 that have been transported and transported are placed on the upper shutter 421.

  Further, as shown in FIG. 9B, the reversing basket 21 and the forward rotation basket 31 are moved by the moving means 5, and the third basket supplied with the group of packaging boxes 10 is moved to the left side of the endless loop. Move to the middle and stop. Further, when the forward rotation conveying means 34 rotates in the clockwise direction and becomes horizontal, the group of packaging boxes 10 placed thereon are in a normal rotation state. Subsequently, the forward conveying means 34 conveys the group of packaging boxes 10 in the normally rotated state to the downstream side, and when the group of packaging boxes 10 moves onto the accumulation conveying means 41, the conveyance is stopped, and the counterclockwise It rotates in the turning direction.

Here, since the packaging box inversion stacking apparatus 1 rotates the group of packaging boxes 10 in a normal direction, the normal rotation can be performed efficiently.
Further, by rotating the group of packaging boxes 10 in a leaning state by about 90 ° in the clockwise direction, the normal rotation state can be obtained, and while the reversing means 2 performs the reversing operation, Since forward rotation is performed, cycle time can be shortened and efficiency can be greatly improved.

FIG. 10: has shown the schematic side view of the principal part for demonstrating operation | movement of the inversion accumulation | stacking apparatus of the packaging box which concerns on embodiment of this invention.
Next, as shown in FIG. 10A, the packaging box inversion stacking apparatus 1 moves the inversion basket 21 and the forward rotation basket 31 by the moving means 5, and the third basket moves to the left side of the endless loop. The reversing rotation means 22 rotates the reversing basket 21 in the counterclockwise direction, and the group of packaging boxes 10 is placed on the reversing conveying means 23 in the reversed state. After that, the reversing basket 21 is rotated in the clockwise direction.
Further, as shown in FIG. 10 (a), the reversing basket 21 and the forward rotation basket 31 are moved by the moving means 5, and the fourth basket is moved to the left side and the middle stage of the endless loop and stopped. The forward rotation basket 31 is rotated clockwise by the normal rotation first rotation means 32 at substantially the same timing as the reversing basket 21 is rotated. In addition, the group of packaging boxes 10 that are moved obliquely downward and are supplied are placed on the forward conveying means 34 with the bottom portion supported by the guide member 33 and the glued portion on the upper surface side.

  Further, as described above, when the reversing basket 21 and the normal rotation first rotating means 32 are rotating, as shown in FIG. 10A, the stacking means 4 supplies from the second basket. Then, the group of packaging boxes 10 in the normal rotation state are conveyed downstream by the accumulation conveying means 41 until they come into contact with the stopper shutter 45. In the dropping means 42, the group of packaging boxes 10 supplied from the first basket and inverted are dropped from the upper shutter 421, and further dropped from the lower shutter 422, and are brought into contact with the stopper shutter 45. It is accumulated on a group of packaging boxes 10 that are in contact with each other in a normal rotation state.

  Next, as shown in FIG. 10B, the packaging box inversion stacking apparatus 1 moves the inversion basket 21 and the forward rotation basket 31 by the moving means 5, and the third basket moves to the right side of the endless loop. When the fourth basket moves to the left side of the endless loop and stops, the reversing transport means 23 moves the group of packaging boxes 10 placed downstream to the downstream side. The group of packaging boxes 10 that have been transported and transported are placed on the upper shutter 421.

  Further, as shown in FIG. 10 (b), the reversing basket 21 and the forward rotation basket 31 are moved by the moving means 5, and the supplied fifth basket of the group of packaging boxes 10 is placed on the left side of the endless loop. Move to the middle and stop. Further, when the forward rotation conveying means 34 rotates in the clockwise direction and becomes horizontal, the group of packaging boxes 10 placed thereon are in a normal rotation state. Subsequently, the forward conveying means 34 conveys the group of packaging boxes 10 in the forward rotated state to the downstream side. Although not shown, the forward conveying means 34 stops conveying and rotates counterclockwise when the group of packaging boxes 10 moves onto the accumulation conveying means 41.

Further, as described above, when the reversing transport means 23 is transported and the normal rotation transport means 34 is rotating, as shown in FIG. 44 rises above the stacking transport means 41 on the upstream side of the stacking transport means 41 and then moves downstream. At this time, the two groups of packed packaging boxes 10 are sandwiched between the stopper shutter 45 and the feeding engagement member 44 so that when dropped, the grouped packaging boxes 10 in an inverted state shifted to the upstream side are dropped. It can be accumulated in a well-organized state on a group of packaging boxes 10 in a normal rotation state.
Subsequently, after correcting the deviation, the stopper shutter 45 is moved to the front side or the back side, for example, and the two groups of the stacked packaging boxes 10 are fed by the feeding engagement member 44 and the stacking transport means 41. , Sent to the downstream side, and usually bound by a binding machine in the next step.

  Here, as described above, the packaging box reversing and accumulating apparatus 1 automatically counts the packaging boxes 11, divides them into predetermined quantities, and supplies them to a group of packaging boxes 10 that are sequentially supplied in a standing state. On the other hand, the inversion means 2 puts the first group of packaging boxes 10 in the inverted state, the normal rotation means 3 puts the second group of packaging boxes 10 in the normal rotation state, and the stacking means 4 has the group of inverted states. The packaging box 10 and the group of packaging boxes 10 in the normal rotation state can be integrated. Therefore, the reversing and accumulating apparatus 1 for packaging boxes can be produced in an almost unmanned state, and the labor cost spent for the reversing operation and the accumulating operation can be greatly reduced.

By repeating the above-described operation, the packaging box reversing and accumulating apparatus 1 reverses or forwardly rotates the group of packaging boxes 10 sequentially supplied from the extruding means 107 to the normal state of the group of packaging boxes 10 in the inverted state. A group of packaging boxes 10 in a rolled state can be collected.
In addition, the two groups of packaging boxes 10 that are accumulated are accumulated with the adhesive surfaces facing each other and the bottoms facing each other.

As described above, according to the packaging box reversing and accumulating apparatus 1 of the present embodiment, the productivity can be significantly improved, and the labor cost can be reduced.
Further, the reliability of the sorting operation can be improved, and damage or dirt due to contact between the packaging boxes 11 can be suppressed.

As mentioned above, although the preferable embodiment was shown and demonstrated about the inversion accumulation apparatus of the packaging box of this invention, the inversion accumulation apparatus of the packaging box which concerns on this invention is not limited only to embodiment mentioned above, this invention It goes without saying that various modifications can be made within the range described above.
For example, the packaging box inversion stacking apparatus 1 has a plurality of inversion baskets 21 and forward rotation baskets 31 and moves them along an endless loop. However, the present invention is not limited to this. For example, although not shown, each of the reversing baskets 21 and the normal rotation baskets 31 is provided, and an elevator for raising and lowering the group of packaging boxes 10 is provided between the sorting means 106 and the pushing means 107, and the pushing means. 107 may be configured to alternately supply the group of packaging boxes 10 to the reversing basket 21 and the forward rotation basket 31. Even if it does in this way, there can exist an effect substantially the same as the inversion accumulation | stacking apparatus 1 of a packaging box.
