Description

The present invention relates to a gluing device and a boxing device including the gluing device.

Conventionally, there is a gluing device that automatically attaches (applies) an adhesive to a predetermined position (for example, a flap) of a box to be conveyed. In addition, many of the gluing devices include a spraying means (nozzle, etc.) for spraying (spraying) the adhesive, and the position of the box is detected by a sensor or the like, and the adhesive is placed at a desired position. Is configured to spout. Then, in the case of adopting a gluing device having a structure in which an adhesive is sprayed from such a nozzle, a technique for preventing the application of the adhesive to a region other than the desired adhesive adhesion region has also been developed.

For example, when applying an adhesive to the adhesive application area (glue flap), the top wall and the adhesive flap cover the article contained in the box, and in that state, the adhesive is applied to the adhesive flap. A gluing device that sprays an adhesive from a feeding device is known (see, for example, Patent Document 1).

In addition, in the box to be transported, the presence or absence of the adhesive application area (the bent state of the flap to which the adhesive is applied) is detected, and if there is an abnormality, the adhesive is not sprayed from the adhesive injection nozzle. Such a packaging device is known (see, for example, Patent Document 2).

Japanese Patent No. 5003290 Japanese Patent No. 4515965

However, in the case of a configuration provided with an adhesive spraying means (nozzle or the like), the spraying means is likely to be clogged by the adhesive, and the adhesive scatters in an unintended direction to form a predetermined adhesive region (coating region). There is a problem that it is not adhered (coated) to the surface and adheres to an unintended area.

In such a case, for example, in the apparatus described in Patent Document 1, adhesion of the adhesive to the article housed in the box can be avoided, but adhesion of the adhesive to an unintended area (area other than the glued flap) (the adhesion of the adhesive to the unintended area (area other than the glued flap)). It cannot be avoided until (scattering).

Further, in the apparatus described in Patent Document 2, if the presence or absence of the adhesive coating region (the bent state of the flap to which the adhesive is applied) is normal, the coating is performed. That is, even in this case, it is not possible to prevent the adhesive from adhering (scattering) to an unintended area (area other than the flap).

The present invention has been made in view of the above problems, and in a gluing device that automatically glues (spouts) an adhesive from a spraying means at a predetermined position of a box to be transported, the spraying means is used. A gluing device that can prevent unintentional adhesion (application) of adhesive to areas other than the predetermined adhesion area (application area) even when the adhesive is scattered due to clogging, etc. It is intended to provide a complete boxing device.

The present invention is a gluing device for adhering an adhesive to a predetermined adhesion region of a box body to be conveyed, wherein the spraying means for spraying the adhesive on the box body and the timing of adhering the adhesive are described.

<Overall configuration>
Hereinafter, the boxing apparatus 1 according to the embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a top view of the boxing device 1, and the right end portion of FIG. 1 (A) is continuous with the left end portion of FIG. 1 (B). Further, FIG. 2 is an external view showing an example of the box body YA1. In this drawing and the subsequent drawings, some configurations will be omitted as appropriate to simplify the drawings, and the size, shape, thickness, etc. of the members will be exaggerated as appropriate.

As shown in FIG. 1, the boxing device 1 of the present embodiment supplies the transport means 3 of the box body YA1, the gluing device 5 arranged so as to line up with the transport means 3, and the box body YA1 on the transport means 3. The box body supply means 7 and the article supply means 9 for supplying the article XA1 into the box body YA1 are provided, and the article XA1 is housed in the box body YA1 while transporting the box body YA1. This is an apparatus for sealing the box YA1 in a state of accommodating the article XA1 by adhering an adhesive to a predetermined region (adhesive adhesion region) and gluing a part of the box YA1.

Each part of the boxing device 1 is collectively controlled by a control means (control unit) (not shown). The control unit is composed of a CPU, RAM, ROM, and the like, and executes various controls. The CPU is a so-called central processing unit, and various programs are executed to realize various functions. The RAM is used as a work area of the CPU. The ROM stores the basic OS and programs executed by the CPU.

Further, in the following description, the width direction of the transport surface (vertical direction in FIG. 1) orthogonal to the transport direction T is transported with reference to the transport direction T (horizontal direction in FIG. 1) of the box body YA1 in the transport means 3. The width direction W is defined, and the direction perpendicular to the transport surface is the transport height direction H.

As shown in FIG. 6A, the box body supply means 7 is, for example, a robot having an arm 71 that can move arbitrarily in a three-dimensional space, and is formed from a hopper 17 or the like in which the box body YA1 in a folded state is stacked. One sheet is taken out and supplied onto the transport means 3.

As an example, the transport means 3 is a means for transporting the box body YA1 by sliding a plurality of movers 33 along the rail 35 by a linear motor (linear drive motor). In this example, the rail 35 extends along (parallel to) the transport direction T of the transport means 3. That is, the mover 33 moves along the transport direction T.

The control unit arbitrarily moves and stops the mover 33 on the rail 35 independently (at an arbitrary distance and at an arbitrary speed). Each of the movers 33 is provided with a flat plate-shaped holding portion 37. The holding portion 37 is erected so that its surface spreads in the transport width direction W and the transport height direction H, for example. Further, in the holding portion 37, two holding portions 37 that are continuous (adjacent) in the moving direction are arranged to face each other to form a set of holding means, and the box body YA1 is sandwiched between them.

The box body YA1 is, for example, a sack box (caramel box) that becomes tubular when four consecutive faces are three-dimensional and has flaps that can be opened and closed on the remaining two facing faces (see FIG. 2). The surfaces with flaps are transported so as to be located on both sides in the transport width direction W.

For example, the box body supply means 7 takes out the unfolded box body YA1 from the hopper 17 or the like and supplies the box body YA1 between the set of holding portions 37 of the transport means 3. The set of holding portions 37 is controlled so as to move close to each other while moving in the transport direction T, and the box body YA1 is held by sandwiching the front and rear ends in the transport direction T between the set of holding portions 37. .. The set of holding portions 37 are further controlled so that they are closer to each other, whereby the folded portion of the four continuous surfaces is pushed, and the two surfaces corresponding to both sides in the transport width direction W are opened. The box body YA1 is boxed in this state. In this way, the transport means 3 transports the folded box body YA1 downstream while opening the box.

In the present embodiment, as an example, a case where the folded box body YA1 is transported while being boxed will be described, but the box body YA1 is in a separately boxed (three-dimensionally assembled) state and is a box. It may be supplied onto the transport means 3 by the body supply means 7, and the transport means 3 in this case may be a belt conveyor, a finger conveyor, or the like.

As shown in FIG. 3B, the article supply means 9 is provided on the downstream side of the box body supply means 7. The article supply means 9 has, for example, a pushing member 91, and the article XA1 is provided from one of the two open surfaces of the boxed box YA1 (the side of the box YA1 in the transport width direction W). Is pushed in and supplied (accommodated) in the box body YA1. The supply of the article XA1 is not limited to the pushing member 91, and the article XA1 may be held by a suction means, a gripping means, or the like and supplied (accommodated) in the box body YA1.

A gluing device 5 is arranged downstream of the article supply means 9. The gluing devices 5 are arranged in pairs on the left and right sides (upper and lower in FIG. 1) of the transport means 3 in the transport width direction W in this example so as to line up (parallel) with the transport means 3. The configuration of the pair of gluing devices 5 is the same.

As will be described in detail later, the gluing device 5 includes at least a spraying means 51 and a guide means 53, and an adhesive (for example, an adhesive adhesion region of a flap) is provided in a predetermined region of the box body YA1. , Hot melt adhesive) is attached.

The spraying means 51 is, for example, an injection nozzle, and is arranged so that a pair of left and right injection ports face each other so that the adhesive can be sprayed toward the center of the transport width direction W of the transport means 3. The spraying means (injection nozzle) 51 is fixed to a machine frame (not shown) and does not move. By injecting an adhesive onto the moving box body YA1 at a predetermined timing, the flap of the box body YA1 is ejected during the movement. The adhesive adheres to the predetermined position.

The guide means 53 is a means for covering a region other than the adhesive adhesion region of the box body YA1 at the timing when the injection nozzle 51 adheres (injects) the adhesive to the box body YA1. The gluing device 5 of the present embodiment is configured such that the injection nozzle 51 adheres (injects) the adhesive to the adhesive adhesion region while covering the region other than the adhesive adhesion region of the box body YA1 by the guide means 53. This makes it possible to prevent the adhesive from scattering (adhering) to a region other than the desired region (adhesive adhesion region).

The box body YA1 of the present embodiment will be described with reference to FIG. FIG. (A) is a top view of the box body YA1 in the folded state (before boxing), and FIG. 3B is an external perspective view showing the box body YA1 in the state of being boxed by the transport means 3. FIG. 3C is a front view of the flap F in a closed state. In addition, in FIG. 2, each direction is shown corresponding to the state of the box body YA1 conveyed in FIG.

As shown in FIG. 2, in the box body YA1, four consecutive surfaces S1 to S4 are bonded together so as to form a cylinder, and a plurality of flaps F (in this example, flaps F1) are attached to each of the two open (opened) surfaces. It is a sack box (caramel box) in which ~ F4) is formed. In the following description, for convenience, the four continuous surfaces S1 to S4 are referred to as peripheral wall surfaces SS, and the surface covered by (or planned to be covered with) the flap F is referred to as the flap surface FS.

With reference to FIG. 3A, the box body YA1 (sack box) has, for example, a peripheral wall surface after forming a gap between S1 and S3 by separating S1 and S3 held by the suction means. When the opposing side portions T, which are mountain-folded in the folded state of the SS, are brought closer to each other in the direction of the broken line arrow, the peripheral wall surface SS becomes three-dimensional as shown in FIG. Then, the article XA1 is housed in the box body YA1 from any one of the open flap surface FSs, and the flaps F (F1 to F4) are bent to close the flap surface FS. For example, the flaps F1 and F3 are provided so as to face the upstream side and the downstream side of the transport direction T, and the flaps F2 and F4 are provided so as to face the upper side and the lower side of the transport height direction H. Be done.

Here, as an example, none of the flaps F is inserted, and the flap surface FS is closed (sealed) by folding and partially adhering the flaps F.

More specifically, after the peripheral wall surface SS is laid in the middle of transporting the box body YA1, first, the flaps F1 and F3 provided on the upstream side and the downstream side of the transport direction T are folded. A part (indicated by a broken line circle) exposed to the outside of the box body YA1 in the folded state is provided with an adhesive adhesion region SP (planned as an adhesive adhesion region SP).

Then, after the adhesive is sprayed from the injection nozzle 51 onto the adhesive adhesion region SP, the flaps F2 and F4 provided on the upper side and the lower side in the transport height direction H are folded. As a result, the flaps F1 and F3 and the flaps F2 and F4 are glued together. After the adhesive is sprayed (applied), the flaps F2 and F4 are bent by, for example, a round bar or a flat plate-shaped fixing guide, and fixed by a pressing means such as a pusher device. As a result, the flap surface FS is closed.

In this example, none of the flaps F (F1 to F4) is inserted and the flap F is closed only by the adhesive. However, in addition to the closure by the adhesive, at least one of the flaps F is inserted. You may.
<Gluing device>
The gluing device 5 of the present embodiment will be further described with reference to FIGS. 3 to 7.

FIG. 3 is a top view of the gluing device 5, FIG. 4 is a side view of the gluing device 5 as viewed from the upstream side, for example, and FIG. 5 is a front view mainly explaining the guide means 53.

As described above, the spraying means (injection nozzle) 51 is fixed at a predetermined position and injects the adhesive onto the box body YA1 transported from the upstream to the downstream. As an example, the injection nozzle 51 is arranged so that the nozzle tips face each other on both sides in the transport width direction W with the transport means 3 interposed therebetween as shown in FIG. A plurality (two in this example) are arranged side by side in the height direction H.

The box body YA1 is transported so that, for example, the flap F3 is located on the downstream side and the flap F1 is located on the upstream side (see FIG. 5). Then, as shown in FIG. 3A, when the flap F3 on the downstream side moves to a position facing the tip of the injection nozzle 51, the injection nozzle 51 adheres toward the adhesive adhesion region SP of the flap F3 on the downstream side. Spray the agent. As a result, the flap F3 has the adhesive adhered to the adhesive adhesion regions SP at the upper and lower two positions in the transport height direction H (see FIG. 5).

The guide means 53 is provided on both sides in the transport width direction W with the transport means 3 interposed therebetween so as to be located between the injection nozzle 51 and the transport means 3. The configurations of the two guide means 53 are similar. The guide means 53 has a guide member 531 and a drive mechanism 533 of the guide member 531. The guide member 531 is moved from the upstream side to the downstream side in synchronization with the movement of the box body YA1, and at least the injection nozzle 51 is an adhesive. Is configured to cover a region other than the adhesive adhesion region of the box body YA1 at the timing of adhering (spraying) to the box body YA1.

As shown in FIGS. 3 and 4, as an example, the drive mechanism 533 slides a plurality of movers 537 along the rail 539 by a linear motor (linear drive motor) (not shown), thereby moving the mover 537. The guide member 531 attached to is moved. The rail 539 extends along (parallel to) the transport direction T of the transport means 3. That is, the mover 537 moves along the transport direction T.

The control unit moves and stops the mover 537 independently on the rail 539 (at any distance and at any speed). The rail 539 is provided, for example, in a straight line parallel to the rail 35 of the transport means 3, and the mover 537 is configured to reciprocate on the straight line along the transport direction T of the box body YA1.

As shown in FIGS. 3 and 5, one guide means 53 is provided with two paired movers 537 on the upstream side and the downstream side on one rail 539, and each of the movers 537 is provided with two movable elements 537. A flat plate-shaped guide member 531 is provided. The guide member 531 is erected so that its surface spreads in the transport direction T and the transport height direction H. The control unit controls to move a part of the pair (one set) of guide members 531 from the upstream to the downstream while superimposing them.

As shown in FIGS. 4 and 5 (A), the left and right (front and back of the transport direction T) flaps F1 and F3 of the box body YA1 are bent in the vicinity of the gluing device 5, but the upper and lower flaps F2 and F4 are bent. The article XA1 which is open and housed in the box body YA1 is transported on the transport means 3 in a state of being exposed from a part of the flap surface FS.

The timing of ejecting the adhesive from the injection nozzle 51 is accurately controlled based on the transfer speed of the box body YA1 by the transfer means 3, and as shown by the solid line arrow in FIG. 3, the adhesives of the flaps F1 and F3 adhere. It is possible to accurately eject the adhesive to the region SP.

Specifically, when the flap F3 on the downstream side moves to a position facing the tip of the injection nozzle 51 as shown in FIG. 3A, the injection nozzle is directed toward the adhesive adhesion region SP of the flap F3 on the downstream side. 51 sprays the adhesive. As a result, the flap F3 has the adhesive adhered to the adhesive adhesion regions SP at the upper and lower two positions in the transport height direction H (see FIG. 5B).

The transport means 3 may be configured to intermittently transport the box body YA1 so as to temporarily stop the box body YA1 when the adhesive is ejected from the injection nozzle 51, or the injection nozzle 51. When the adhesive is sprayed from the box body YA1, the transport speed of the box body YA1 may be reduced.

When the transport means 3 moves the box body YA1 and the flap F1 on the upstream side moves to a position facing the tip of the injection nozzle 51 as shown in FIG. 3 (B), the adhesive adhesion region of the flap F1 on the upstream side The injection nozzle 51 injects the adhesive toward the SP. As a result, the flap F1 has the adhesive adhered to the adhesive adhesion regions SP at the upper and lower positions in the transport height direction H (see FIG. 5 (B)).

At this time, since the injection nozzle 51 ejects the adhesive from the narrow ejection holes, for example, the ejection holes may be clogged. If the adhesive is ejected in this state, the adhesive may adhere (scatter) to an unintended region as shown by the broken line arrow in FIG. Further, as shown in FIGS. 4 and 5 (A), a part of the surface (flap surface FS) including the adhesive adhesion region SP of the box body YA1 is opened at the timing of application (adhesion) of the adhesive. The article XA1 housed inside is exposed.

That is, even if the timing of ejecting the adhesive of the injection nozzle 51 is accurately controlled, the adhesive may scatter, and the scattered adhesive may be exposed from the box body YA1 or the box body. If it adheres to an unintended area such as the inside of YA1, there is a problem that the article XA1 cannot be repacked or the finished product is poor.

Therefore, in the gluing device 5 of the present embodiment, at least at the timing when the injection nozzle 51 adheres (injects) the adhesive to the adhesive adhesion region SP, the guide means 53 uses the guide means 53 to cover the region other than the adhesive adhesion region of the box body YA1. It was configured to adhere (spray) the adhesive to the adhesive adhesion region SP while covering it.

Specifically, as shown in FIG. 5, the guide means 53 moves from the upstream side to the downstream side as the box body YA1 is conveyed, and the injection nozzle 51 adheres the adhesive (injection) to the adhesive adhesion region SP. ), The movement is controlled by a pair of guide members 531 so as to cover at least the area of the flap surface FS between the flaps F1 and the flap F3 where the inside is exposed (hereinafter, referred to as "exposed area EP"). (FIGS. 3 and 5 (B)).

Then, at least at the timing when the exposed region EP is covered by the pair of guide members 531 (after being covered), the injection nozzle 51 adheres (injects) the adhesive to the adhesive adhesion region SP.

More specifically, as shown in FIG. 3A, the guide means 53 is paired so as to cover the exposed region EP by the timing when the flap F3 on the downstream side moves to a position facing the tip of the injection nozzle 51. The guide member 531 is being moved. Then, the injection nozzle 51 injects the adhesive toward the adhesive adhesion region SP of the flap F3 on the downstream side while covering the exposed region EP by the pair of guide members 531 (FIG. 5B).

Further, when the transport means 3 moves the box body YA1, the guide means 53 moves the pair of guide members 531 so as to cover the exposed region EP in synchronization with this. Then, as shown in FIG. 3B, the injection nozzle is at the timing when the flap F1 on the upstream side moves to a position facing the tip of the injection nozzle 51 while the exposed region EP is covered by the pair of guide members 531. 51 sprays the adhesive toward the adhesive adhesion region SP of the flap F1 on the upstream side (FIG. 5 (B)).

As a result, even if the adhesive is scattered in a region other than the desired region (adhesive adhesion region SP) due to clogging of the injection nozzle 51 or the like, an unintended region (exposed region) It is possible to prevent the adhesive from adhering to the EP or the inside of the box body YA1).

The guide means 53 can individually move and control the pair of guide members 531. That is, the amount of superimposition (superimposition amount) of the pair of guide members 531 can be adjusted. Therefore, even if the area of the exposed region EP changes due to a change in the box body YA1, the exposed region EP can be reliably covered by changing the overlapping amount of the guide member 531 according to the exposed region EP. it can.

As shown by the broken line arrow in FIG. 4A, the rails 539 of the guide means 53 in the transport width direction W are also configured to be movable in the transport width direction W, respectively. Thereby, the distance between the two rails 539 (the length of the transport width direction W) can be adjusted according to the outer shape of the box body YA1.

After the adhesive is attached, the guide means 53 is moved upstream at a speed faster than the speed at which the guide means 53 and the box body YA1 move in the transport direction in synchronization with each other. After that, as shown in FIG. 4B, the upper and lower flaps F2 and F4 are bent and adhered to the flaps F1 and F3, and the flap surface FS is closed (sealed).

The bending of the upper and lower flaps F2 and F4 will be described with reference to FIG. 6A and 6B are views for explaining a guide for bending the upper and lower flaps F2 and F4, and FIGS. (A) and (E) are front views, and FIGS. FIGS. (F) to (H) are side views seen from, for example, the upstream side.

The upper and lower flaps F2 and 3 are bent by, for example, the upper flap folding guide 151 and the lower flap folding guide 153.

With reference to FIG. 3A, the upper flap folding guide 151 is a substantially flat plate-shaped member arranged to face each other on both sides in the transport width direction W, and the upstream side in the transport direction T is an inclined side 151S. It has become. The inclined side 151S is a side that is inclined so that the lower end is located on the downstream side from the upper end and the length (height) of the upper flap folding guide 151 in the transport height direction H becomes longer from the upstream to the downstream side. is there.

Further, the separation distance of the upper flap folding guides 151 arranged to face each other is set to be slightly wider than the length (width) of the box body YA1 in the transport width direction W.

As a result, when the box body YA1 is conveyed to the upstream side of the upper flap folding guide 151, the upper flap F2 comes into contact with the upper flap folding guide 151, and the flap F2 is pushed in as it is and folded downward. Then, the flap F2 is pushed down along the inclined side 151S and automatically bent (FIGS. (B) to (D)).

Further downstream, a lower flap folding guide 153 is provided. The lower flap folding guide 153 is a substantially flat plate-shaped member arranged to face each other on both sides in the transport width direction W, and the upstream side in the transport direction T is an inclined side 153S. The inclined side 153S is a side that is inclined so that the lower end is located on the upstream side from the upper end and the length (height) of the lower flap folding guide 153 in the transport height direction H becomes shorter from the upstream to the downstream side. is there.

Further, the separation distance of the lower flap folding guides 153 arranged to face each other is set to be slightly wider than the length (width) of the box body YA1 in the transport width direction W.

As a result, when the box body YA1 is conveyed to the upstream side of the lower flap folding guide 153, the lower flap F4 comes into contact with the lower flap folding guide 153, and the flap F4 is scooped up as it is and automatically bent. Go (Fig. (F) to Fig. (H)).

The arrangement of the upper flap folding guide 151 and the lower flap folding guide 153 may be reversed (the lower flap folding guide 153 is upstream).

The upper flap folding guide 151 and the lower flap folding guide 153 are fixed to, for example, a machine frame (not shown).

FIG. 7 is a top view showing another example of the guide means 53. As shown in the figure, the guide means 53 is configured to move in a circular manner, and in a part of the section, moves linearly along the transport direction T of the box body YA1 in synchronization with the transport of the box body YA1. It may be configured as follows.

The rail 539 of the guide means 53 is provided in an annular shape (in this example, an oval (track) shape) having a straight portion ST parallel to the rail 35 of the transport means 3 in a part of the section, and the mover 537 is the rail 539. Orbits in the horizontal plane in one direction (indicated by the broken arrow arrow).

Further, a plurality of sets of guide members 531 covering the exposed region EP are provided on one rail 539. When turning, the set of guide members 531 moves apart from each other without superimposing a part of each other, and a predetermined amount of a part of each other is superposed on the straight line portion and synchronizes with the box body YA1. Move downstream.

As shown in FIGS. 1 and 3, in the configuration in which the rail of the guide means 53 is linearly configured and the mover (guide member) is linearly reciprocated, the time and control for the guide member to return from the downstream side to the upstream side are controlled. However, as shown in FIG. 5, it is preferable to move the guide members in a plurality of sets because the cycle time can be improved.

The rail 539 in this case may have a configuration in which the guide means 53 can orbit around in one direction, and is not limited to an annular shape including an arc shape (in this example, an oval (track) shape), but has a substantially polygonal shape. It may be annular (endless shape) or the like.
<Modification example>
8A and 8B are views showing another example of the guide means 53, in which FIG. 8A is a side view seen from, for example, the upstream side, and FIG. 8B is a front view.

In the above-described embodiment, the rail 539 of the guide means 53 exemplifies a configuration in which the rail 539 of the guide means 53 is located near the substantially center of the box body YA1 in the transport height direction H (see FIG. 5). The flap surface FS of the box body YA1 has four flaps F1 to F4 including the upper and lower flaps F2 and F4, and the upper and lower flaps F2 and F4 which are in an open state in the adhesive spraying process and the upper and lower flaps F2 and F4. There is a possibility of interference with the guide member 531. Therefore, the position of the rail 539 is provided near the substantially center of the box body YA1 in the transport height direction H to avoid interference between the upper and lower flaps F2 and F4 and the guide member 531.

However, the above example is not limited as long as the configuration can avoid interference between the upper and lower flaps F2 and F4 in the open state and the guide member 531.

In the example of the figure, the flap surface FS has only the left and right flaps F1 and F3 and one flap above or below (for example, flap F2). In this case, the guide member 531 only needs to avoid interference with the flap F2, and the rail 539 is arranged near the bottom surface of the box body YA1 below the transport height direction H, and the guide member 531 stands on the mover 537. It may be set up. Further, the rail 539 may be arranged above the transport height direction H close to the flap F2 so as to suspend the guide member 531 from the mover 537.

FIG. 9 describes yet another example of the guide means 53. FIG. (A) is a top view showing another example of the guide means 53, and FIG. (B) is a side view.

The guide means 53 is not limited to the above example as long as it covers a region other than the adhesive adhesion region of the box body YA at the timing of adhering the adhesive, and is, for example, a configuration that does not move (fixed). May be good.

That is, the guide means 53 of the above embodiment moves the guide member 531 synchronously with the box body YA1, that is, moves relative to the fixed (non-moving) injection nozzle 51. It was composed of.

On the other hand, the guide means 53 shown in the figure is similarly fixed to, for example, a machine frame to which the injection nozzle 51 is fixed so that the guide member 531 does not move relative to the injection nozzle 51. The guide member 531 is a flat plate-shaped member erected so that its surfaces spread in the transport direction T and the transport height direction H, and is an adhesive adhesion region on the downstream side (front side of the transport direction T) of the box body YA1. When the SP is located at the opposite position of the injection nozzle 51, the exposed region EP of the box body YA1 is arranged so as to be shielded.

When the adhesive is ejected from the injection nozzle 51, the transport means 3 temporarily stops the box body YA1 or slows down the transport speed of the box body YA1, and the jet nozzle 51 uses the adhesive exposed from the guide member 531. The adhesive is sprayed onto the adhesion region SP. In this example, the guide member 531 may be configured so that the length in the transport direction T can be adjusted.

According to such a guide means 53, even if the adhesive adheres (scatters) to an unintended area due to clogging of the injection nozzle 51 or the like, an unintended area (at least the exposed area EP of the box body YA1). In addition, it is possible to prevent the adhesive from adhering (scattering).

In the case of the fixed guide member 531 shown in the figure, when the glue (adhesive) of the gluing device 5 is poorly cut (stopped), the adhesive adhering to the box body YA1 passes through the exposed region EP. It may adhere to XA1. Therefore, as shown in FIGS. 1 to 8, it is more desirable that the guide member 531 is moved in the transport direction T in synchronization with the box body YA1.

Further, as shown in FIG. 10, the box body YA1 may be a so-called one-touch box. FIG. (A) is a plan view in a folded state, FIG. (B) is an external perspective view in a boxed state, and FIG. (C) is a front view in a boxed and transported state.

The FS one-touch box is also called a one-touch bottom, a one-touch bottom box, a one-touch carton, etc. It is a box body configured so that the bottom B can be combined by three-dimensionalizing the peripheral wall surface SS from the folded state. Here, as an example, a one-touch box in which the lid portion F0 covering the upper opening in the assembled state is continuously provided at the upper end of the peripheral wall surface SS on the rear side will be described.

In this case, if the opposing side portions T, which are mountain-folded in the folded state shown in FIG. 6A, are brought closer to each other in the direction of the arrow, the peripheral wall surface SS becomes three-dimensional, and accordingly. The bottom B is automatically combined. As an example, if the opposing side portions T are urged in the direction of the arrow or the two peripheral wall surfaces SS that overlap vertically in the folded state are separated from each other, the peripheral wall surface SS becomes three-dimensional. In this case, the flap surface FS is the surface on which the lid portion F0 and the flaps F1 and F2 are provided.

The boxing device 1 includes a box body supply means 7, an article supply means 9, and a gluing device 5 similar to those in FIG. That is, the box body supply means 7 takes out the folded box body YA1 from the hopper or the like and supplies the box body YA1 between the set of holding portions 37 of the transport means 3. The set of holding portions 37 is controlled so as to move close to each other while moving in the transport direction T, and the box body YA1 is held by sandwiching the front and rear end portions T in the transport direction T between the set of holding portions 37. To. The set of holding portions 37 are further controlled so that the distances from each other are closer to each other, whereby the peripheral wall surface SS is boxed and three-dimensionalized, and the bottom portion B is automatically combined accordingly. The flap surface FS in the open state is transported so as to be located on one side of the transport width direction W.

The article supply means 9 has, for example, a pushing member 91, and pushes the article XA1 from the flap surface FS (side of the box body YA1 in the transport width direction W) in the opened state of the boxed box body YA1 to push the box body YA1 into a box. It is supplied (accommodated) in the body YA1.

A plurality of pushing members 91 may be provided, and the article XA1 may be pushed in while moving the box body YA1 to be housed in the box body YA1.

After that, for example, in the gluing device 5 shown in FIG. 3 or 7, the adhesive is ejected from the injection nozzle 51 toward the adhesive adhesion region SP with the exposed region EP between the flaps F1 and F2 covered. .. Then, after the guide member 531 moves downstream, the lid portion F0 is bent and adhered to the flaps F1 and F2. The injection nozzle 51 is provided only on the side where the lid FO of the box body YA1 is located. Alternatively, the glue is not applied from the injection nozzle 51 on the side opposite to the lid FO of the injection nozzle 51 provided on both sides in the transport direction W. That is, the injection nozzle 51 is configured so that it is possible to switch between the need for coating and the need for coating.

<Other Embodiments>
FIG. 11 is a front view showing another example of the boxing device 1, and is an example of a boxing device 1 provided with an adhesive misalignment correction device 11 that prevents misalignment when the flap F is adhered.

The adhesion misalignment correction device 11 is provided, for example, on the downstream side of the gluing device 5 in the above embodiment and on the upstream side of the bonding process of the upper and lower flaps F (flaps F2 and F4).

In the box body YA1, the peripheral wall surface SS is boxed by the holding portion 37 of the transporting means 3, but as shown in FIG. 11, the boxing is not sufficient, and the upper surface during transportation is slightly upstream from the lower surface. It may become a parallelogram that has collapsed (distorted) so as to shift to. If the upper and lower flaps F2 and F4 are bent and attached in this state, there is a risk of causing adhesive misalignment (adhesion misalignment). Therefore, the adhesive misalignment correction device 11 corrects the adhesive misalignment.

As shown in FIG. 3A, the adhesive misalignment correction device 11 is, for example, an attach conveyor, and includes a timing belt 111, a pressing means 115, a pulley 113, a servomotor (not shown), and the like. The adhesive misalignment correction device 11 is arranged above the conveying means 3 in parallel with the conveying means 3 and moves in the conveying direction T of the pressing means 115.

The pressing means 115 is attached to the timing belt 111 at predetermined intervals, and extends vertically downward on the lower side of the timing belt 111.

The timing belt 111 is wound around the pulley 113, and the pulley 113 is driven by a servomotor (not shown). By the servomotor, the pressing means 115 comes into contact with the box body YA1 from above on the rear side, moves in the transport direction at the same speed as the transport means, and corrects a slight deviation of the box body YA1.

Specifically, the pressing means 115 is configured to be able to come into contact with the upstream upper end portion of the box body YA1. Then, for example, the pressing means 115 moves behind the box body YA1 in the vicinity of the pulley 113 on the upstream side of the adhesive misalignment correction device 11, and gradually increases in speed to the upstream upper end portion of the preceding box body YA1. Contact from (upstream side). After that, the pressing means 115 moves slightly faster than the transport speed of the transport means 3, and pushes the upper end portion of the box body YA1 on the upstream side forward (downstream side). As a result, even if the box body YA1 is slightly distorted, it can be corrected and its shape can be corrected so that the adhesive deviation does not occur.

The shape of the pressing means 115 is, for example, a flat plate shape similar to that of the holding portion, but is not limited to this, and may be a square bar or a cylindrical bar, and has an inverted L shape when viewed from the front. It may be a plate.

The distortion of the parallel quadrilateral shape of the box body YA1 can be detected by, for example, acquiring an image of the outer shape of the box body YA1 and the adhesion position of the adhesive with a camera. Then, when it is detected that the box body YA1 is distorted and a misalignment (positional misalignment) is likely to occur, the servomotor is fed back, and if necessary, the timing belt 111 is moved back and forth or pressed by the servomotor. Control is performed so that distortion can be reliably corrected by changing the position of the means 115.

As shown in FIG. 3B, the adhesive misalignment correction device 11 is not limited to the attach conveyor, and a plurality of movers to which the holding means 115 is attached by an annular linear motor in which the movers move around in a vertical plane are individually attached. It may be configured to move / stop at an arbitrary speed.

Since each pressing means 115 can be moved / stopped at an arbitrary speed, for example, in the vicinity of the pulley 113 on the upstream side of the adhesive misalignment correction device 11, the pressing means 115 moves later than the box body YA1 and gradually increases in speed to precede. After contacting the upper end portion of the box body YA1 on the upstream side from the rear (upstream side), the box body YA1 can be moved at the same speed as the transport speed of the transport means 3 (holding portion). That is, while pushing the upper end portion of the box body YA1 on the upstream side forward (downstream side), the holding portion and the pressing means 115 can maintain an appropriate shape and convey the box body YA1 for a long period of time. Reliable correction can be performed. Further, even if the degree of distortion of the individual box body YA1 is different, the degree of correction can be adjusted individually and flexibly.

An upper flap folding guide 117 is provided on the downstream side of the adhesive misalignment correction device 11. Further, although not shown, a lower flap folding guide is also provided. Since the configurations of the upper flap folding guide 117 and the lower flap folding guide are the same as those of the upper flap folding guide 151 and the lower flap folding guide 153 described above, the description thereof is omitted here.

In this example, the shape is corrected by the adhesive misalignment straightening device 11 after the adhesive is sprayed by the gluing device 5, but the adhesive misalignment straightening device 11 is provided on the upstream side of the gluing device 5. , The shape may be corrected before and between the spraying of the adhesive. In this case, the flap folding guide 117 is not required for the adhesive misalignment correction device 11.

FIG. 12 is a view showing another example of bending of the flap F4, and is a side view seen from the upstream side as in FIG. 8A.

As shown in the figure, the flap F4 may be transported in a state of being bent 90 degrees in the direction opposite to that at the time of sealing before spraying (applying) the adhesive. As a result, the guide member 531 can cover the area closer to the opening of the box body YA1.

FIG. 13 is a diagram showing another example of the box body supply device 7. As shown in FIG. 6A, the box body supply device 7 may be a rotary type supply device arranged above the transport means 3. The box body supply device 7 of this example has a plurality of holding means (for example, suction portions) 703 that are rotatably supported by bearings (not shown) provided on the turntable 701. A stocker 705 that stocks the folded box body YA1 in a laminated state is arranged near the outer periphery of the turntable 701, and the box body YA1 in the stocker 705 is configured to be sucked by the suction portion 703. Below the turntable 701, a rotating arm 709 provided with an auxiliary suction portion 707 capable of sucking the folded box body YA1 at the rotating end is provided. The rotating arm 709 can rotate up and down with the lower end shaft support portion 711 as a fulcrum, and the box body YA1 is laid up by the rotating arm 703 and the suction portion 701 as shown by the broken line, and the conveyor means. It is conveyed by 3 (for example, a belt conveyor or the like).

Further, as shown in FIG. 3B, the box body supply device 7 may be a supply device in which the take-out arm 723 of the box body YA1 swings and rotates.

The box body supply device 7 includes a take-out arm 723 that repeatedly swings and rotates around a support shaft 721, and a plurality of holding means (for example, a suction portion) 725 are provided on the tip end side of the take-out arm 723. There is. The folded box body YA1 is accumulated in the stocker (magazine) M, held by the suction portion 725, and is taken out by swinging rotation around the support shaft 721 of the take-out arm 723.

The take-out arm 723 has a guide 727 (roller 727A, swing rotation circle) in which a part of the box body YA1 located far from the support shaft 721 during the swing rotation is arranged inside the swing rotation radius of the take-out arm 723. The guide plate 727B) that bends or bends along the shape of When one suction unit 725 stops the suction operation at the timing when a part of the box body YA1 approaches the guide 727, the box body YA1 is guided by the swing rotation of the take-out arm 723 and the suction operation of the other suction unit 725. It comes into contact with 727 and is boxed.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and technical idea.

That is, in the above embodiment, the position, size, length, shape, material, orientation, etc. of each configuration can be appropriately changed.

For example, the box body supply means 7 may supply the box body YA1 separately boxed by another robot or the like to the transport means 3. Further, in this case, the transporting means 3 may be a belt conveyor or the like having no mover (because it is not necessary to raise the box).
