Description

  The present invention relates to a boxing device for packing a plurality of articles as a set.

  When shipping cellophane tape, a plurality of cellophane tapes individually wrapped in a film are collected by an accumulating device and then packed by a boxing device. In a boxing device, a plurality of cellophane tapes bundled so as to be laterally connected in an upright state are supported by being sandwiched from both ends, and are packed by inserting them into a paper box having both the lid and the bottom opened (Fig. 10 (A) → see FIG. 10 (B)). As a result, the cellophane tape can be stably packed without falling down. Note that in FIGS. 10A and 10B, illustration of a film in which cellophane tape is individually wrapped is omitted, and the drawings are simplified.

  In the case of a conventional boxing device, it is necessary to firmly support a paper box that is difficult to maintain its shape because both the lid and the bottom are open, and supports multiple inserted cellophane tapes. However, since it is necessary to close both the lid and the bottom of the paper box, there is a problem that the boxing apparatus becomes complicated and large, and there is a limit to shortening the cycle time of boxing.

  In order to solve these problems, the inventor considered that at least the paper box with the bottom closed needs to be packed. In order to realize such boxing, it is assumed that the can lid bagging device described in Patent Document 1 is applied. This bagging device inserts a can lid, which is bundled upright on a conveying surface, into a bag disposed on an upwardly inclined conveying surface so that the opening faces diagonally downward so as to be pushed from diagonally below. When such a bag filling device is applied, it is possible to pack the paper in a paper box whose bottom is closed.

  Alternatively, it is assumed that the confectionery bag stacking device described in Patent Document 2 is applied. This stacking device stacks the confectionery bags by dropping them into the tray and stacking the confectionery bags side by side. The confectionery bags accumulated in the tray are conveyed to the boxing device together with the tray. When such an integrated device is applied, the cellophane tape is handled in a laid state, and it is not necessary to stand the cellophane tape, and the factors that make the boxing unstable can be reduced.

Japanese Patent No. 3419494 (see paragraphs [0038] to [0040] and FIG. 5) Japanese Utility Model Publication No. 53-033574 (see FIG. 2)

  However, when the bagging device described in Patent Document 1 is applied, a plurality of cellophane tapes are pre-stacked so as to be arranged in the transport direction on the transport path, while a paper box is placed on the transport path of the cellophane tape. Will be set. For this reason, it is necessary to wait for a plurality of accumulated cellophane tapes until the paper box is set on the transport path of the cellophane tape, and there is still a limit to shortening the cycle time of boxing.

  And even if it is a case where the integration | stacking apparatus described in patent document 2 is applied, the device which contributes to shortening of the cycle time of boxing is not made | formed. In addition, it is necessary to transport a plurality of cellophane tapes in a stacked state, and the aligned state of the stacked products may be lost. In addition, since a plurality of cellophane tapes in a stacked state are separately transferred from a tray to a boxing device, a pusher device or the like is separately required, which causes a problem that the facility as a whole becomes complicated and large.

  Such a problem is not limited to the case of packing the cellophane tape, but may be common in the case of similarly packing other stationery items or various articles such as foods and daily necessities.

  The present invention has been made in view of the above problems, and an object thereof is to provide a boxing device that realizes stable boxing and shortening of the cycle time of boxing without increasing the complexity and size.

Adjust to hold the side. This is because the opening (top surface) side becomes a reference when filling the package XA1 into the paper box YA1. Thus, since the position of the height direction of the paper box YA1 held between the pair of arms 41a of the supply means 40 is adjusted by the lifting device 78, it is possible to deal with various paper boxes YA1 having different heights.

  The actual box conveying means 80 shown in FIGS. 1 and 9 sequentially conveys the paper box YA1 in which a plurality of packaging bodies XA1 are placed. Specifically, the actual box conveying means 80 includes an elevating surface 81a, a conveying surface 81b, a plurality of fingers 82, and the like.

  The elevating surface 81a includes a power source (not shown) such as a servo motor and moves up and down. The raising / lowering surface 81a moves up and down by a preset amount according to the height of the paper box YA1, and prepares for placing the paper box YA1. This is because the pair of arms 61a of the return means 60 has the opening (top surface) side of the paper box YA1 sandwiched regardless of the height of the paper box YA. By the operation of the return means 60, the paper box YA1 in which the plurality of packaging bodies XA1 are put inside is sequentially placed on the lifting surface 81a so that the opening is in an upward state. Thereafter, the elevating surface 81a is automatically positioned up by the required dimension. Thereby, the raising / lowering surface 81a and the conveyance surface 81b become flush. The plurality of fingers 82 advance and retreat above and below the elevation surface 81a and the conveyance surface 81b, and travel along the conveyance direction (the direction from left to right in FIG. 1), so that the paper box on the elevation surface 81a and the conveyance surface 81b. YA1 is conveyed.

  The ear fold means 90 is arranged in the middle of the actual box transport means 80. The ear folding device 90 pushes the ears of the plurality of packaging bodies XA1 placed inside the paper box YA1 placed on the conveying surface 81 with the opening facing upward into the paper box YA1. Specifically, the ear fold means 90 includes a pair of rod-shaped members 91 that advance and retract in the vertical direction. The pair of rod-shaped members 91 are respectively inserted into the paper box YA1 from above the paper box YA1. Accordingly, the ears of the plurality of packaging bodies XA1 placed inside the paper box YA1 are pushed into the inside of the paper box YA1. Each of the pair of rod-shaped members 91 includes a spring 91a, and contracts when a force of a predetermined level or more is applied separately from the up and down movement. As a result, when the pair of rod-shaped members 91 are inserted inside the paper box YA1, they are contracted and retracted when they are caught by something and cannot be inserted.

  Next, the flow of the package XA1 will be described with reference to FIG.

  The plurality of package bodies XA1 are sequentially supplied one by one from the previous process in a lying state. The plurality of packaging bodies XA1 in a laid-down state are sent out one by one to the accommodating portion 22 by the sending means 10. The plurality of packaging bodies XA1 sent out one by one to the housing portion 22 are accumulated in the housing portion 22 in a stacked state. The plurality of packages XA1 stacked in a stacked state in the storage unit 22 are transported from the first position PO1 to the third position PO3 by the storage means 20. The plurality of packages XA1 transported to the third position PO3 are pushed up by the push-up means 50 and placed inside the paper box YA1.

  Next, the flow of the empty paper box YA1 will be described with reference to FIG.

  The plurality of paper boxes YA1 are sequentially supplied one by one from the previous process equipment so that the openings are aligned in a row with the openings facing upward. The plurality of paper boxes YA1 supplied in one row are increased in two rows in the process of being conveyed by the empty box conveying means 70. As a result, it is possible to perform boxing simultaneously on the two paper boxes YA1 in parallel. The two paper boxes YA <b> 1 arranged and conveyed are arranged by the supply means 40 so as to be swung around the horizontal axis so that the opening is in a downward state above the accommodating portion 22. The two paper boxes YA1 disposed above the storage unit 22 are conveyed by the storage unit 20 from the second position PO2 to the third position PO3. A plurality of packages XA1 pushed up by the push-up means 50 are placed inside the two paper boxes YA1 conveyed to the third position PO3.

  Next, the flow of the paper box YA1 after the plurality of packaging bodies XA1 are placed inside will be described with reference to FIG.

  The two paper boxes YA1 in which the plurality of packaging bodies XA1 are put inside are swung around the horizontal axis by the return means 60 and arranged on the transport surface 81 so that the opening faces upward. The two paper boxes YA1 arranged on the conveyance surface 81 are conveyed by the fingers 82 and sequentially supplied to the ear folding means 90 one by one. The plurality of packages XA1 placed inside the paper box YA1 supplied to the ear folding means 90 are pushed into the inside of the paper box YA1 by the ear folding means 90. Thereafter, in a subsequent step, the lid of the paper box YA1 is closed.

  Thus, according to the boxing apparatus 1, a plurality of packaging bodies XA <b> 1 can be accumulated in the storage means 20. For this reason, it is not necessary to provide the stacking device separately from the boxing device 1, and the stacking device can be omitted. As a result, it is possible to prevent complication and enlargement of the entire facility including the boxing device 1.

  Then, while the paper box YA1 is supplied above the storage means 20, a plurality of packaging bodies XA1 can be accumulated in the storage means 20. For this reason, it is not necessary to accumulate and wait for a plurality of packaging bodies XA1 in advance, thereby eliminating time waste. As a result, the packaging cycle time can be shortened.

  Further, the plurality of packaging bodies XA1 in a stacked state are pushed up toward the bottomed paper box YA1 with the opening facing downward, and the plurality of packaging bodies XA1 are put inside the paper box YA1, so that the packaging body XA1 falls down. Without this, stable boxing can be realized.

  Further, the step of accumulating the plurality of packaging bodies XA1, the step of supplying the paper box YA1, and the step of placing the plurality of packaging bodies XA1 inside the paper box YA1 are performed simultaneously at different positions PO1, PO2, PO3. It can be carried out. Thereby, the cycle time of boxing can be shortened compared with the case where each process is performed in order one by one as in the prior art.

  And since the some accommodating part 22 is respectively inclined and arrange | positioned, the several package XA1 can be integrated | stacked in the state of the inclined stacking. For this reason, even when the packaging body XA1 exhibits a rolling shape such as a ring shape, a plurality of packaging bodies XA1 are stacked upright as in the conventional case (FIGS. 10A and 10B). Unlike the reference), the packaging body XA1 is unlikely to roll. As a result, stable boxing can be realized. Moreover, if the case where it accumulates in the state of stacking vertically is assumed, the position of the package XA1 is not constant in the horizontal plane. On the other hand, according to the boxing apparatus 1, since the packaging body XA1 is positioned on the side wall of the accommodating portion 22 on the inclined side, the packaging body XA1 can be smoothly put into the paper box YA1.

  In addition, since the height of the lower support means 31 is sequentially adjusted, the plurality of packaging bodies XA1 sent out by the sending means 10 are dropped sequentially and smoothly in the stacking direction without dropping in the stacking direction. Even if it is a case, the head can be made small and received in the accommodating means 20. Thereby, several package XA1 can be integrated | stacked in the state in order. As a result, stable boxing can be realized.

  Furthermore, since the supply means 40 is provided, the top and bottom of the paper box YA1 can be reversed. For this reason, it is not necessary to receive the paper box from the previous process in the upside down state where the flap or the lid interferes with the mounting surface, and if the paper box YA1 is received from the empty box conveying means 70 as the previous process with the opening facing upward. Good. As a result, the paper box YA1 can be easily received, and the entire apparatus including the boxing apparatus 1 can be prevented from becoming complicated and large.

  By the way, when it is assumed that a plurality of packaging bodies XA1 are stacked in a vertically stacked state, it is necessary to supply the paper box YA1 by reversing the opening 180 degrees from the upward state. On the other hand, in the case of the present embodiment, the plurality of storage portions 22 are respectively arranged to be inclined, and the plurality of packaging bodies XA1 are stacked in a stacked state, so that the paper box YA1 is opened upward. From this state, it may be supplied by reversing it by an angle smaller than 180 degrees. Thus, since the angle at which the paper box YA1 is inverted is reduced, the time required for supplying the paper box YA1 can be shortened. As a result, the packaging cycle time can be shortened.

  Since the returning means 60 is provided, the paper box YA1 can be turned upside down. For this reason, the paper box YA1 after the plurality of packaging bodies XA1 are placed can be reversed and placed on the mounting surface so that the opening is in an upward state. As a result, handling after putting a plurality of packaging bodies XA1 becomes easy, and complication and enlargement of the entire equipment including the boxing device 1 can be prevented.

  By the way, it is assumed that after placing a plurality of packaging bodies XA1 stacked in a vertically stacked state inside the paper box YA1, the paper box YA1 is placed on the mounting surface so that the opening is in an upward state. The paper box YA1 needs to be reversed by 180 degrees and returned. On the other hand, in the case of the present embodiment, after the plurality of packaging bodies XA1 accumulated in an inclined stacked state are placed inside the paper box YA1, the paper box YA1 is placed on the mounting surface so that the opening is in an upward state. Therefore, the paper box YA1 may be reversed by an angle smaller than 180 degrees. As described above, since the angle for reversing the paper box YA1 is reduced, the time required for returning the paper box YA1 can be shortened. As a result, the packaging cycle time can be shortened.

  Further, since the article fall prevention mechanism 62 is provided, the paper box YA1 is reliably returned without dropping the plurality of packaging bodies XA1 placed inside the paper box YA1, and the opening is in an upward state. Can be placed on the mounting surface. As a result, stable boxing can be realized.

  Furthermore, since the return means 60 includes the turning mechanism 63 for turning the holding mechanism 61 and the article drop prevention mechanism 62 integrally around the horizontal axis, the return means can be configured with a simple structure. As a result, the boxing device 1 can be prevented from becoming complicated and large.

  Since the ear folding means 90 is provided, the ear of the package XA1 can be pushed into the inside of the box, and the ear of the package XA1 can be prevented from protruding from the opening of the paper box YA1. As a result, stable boxing can be realized.

  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 thereof.

  That is, in the above embodiment, the position, size, length, shape, material, orientation, and the like of each component can be changed as appropriate. Moreover, in the said embodiment, you may apply the structure of another form in the possible range.

  Or in the said embodiment, after pushing up by the raising means 50 and putting the package XA1 in paper box YA1, the opening of paper box YA1 was made downward like the apparatus disclosed by Japanese Patent Publication No. 05-079566, for example You may make it seal in a state.

  Alternatively, when the packaging capacity is low, as in the above embodiment, the position for receiving the package XA1 (first position PO1 in the above embodiment) and the position in which the package XA1 is placed in the paper box YA1 (the first in the above embodiment). The third position PO3) only needs to be different, and the position for supplying the paper box YA1 (second position PO2 in the above embodiment) and the position for putting the package XA1 into the paper box YA1 (third position PO3 in the above embodiment). May be the same. That is, in the above-described embodiment, the paper boxes YA1 are supplied upward from the fourth position (corresponding to the first position PO1 in the above-described embodiment) through which the plurality of storage units 22 of the transport unit 20 receive a plurality of articles. You may make it move to the 5th position (equivalent to 2nd position PO2 and 3rd position PO3 in the said embodiment) which puts the some package XA1 inside the upper paper box YA1.
