Description

  The present invention relates to a boxing device for packing a flexible bag body in which noodles and the like are packed into a storage box.

  Traditionally, noodles such as Chinese noodles and buckwheat noodles produced at a noodle factory are packaged in a bag formed of a resin film or the like, and then packed in a storage box and shipped. Since the boxing operation of each bag body into the storage box is complicated, in recent years, it is common to pack each bag body into the storage box using a boxing device.

  For example, the boxing device disclosed in Patent Document 1 is arranged side by side below the upper conveyor, and dropped from the upper conveyor, which conveys each bag and sequentially drops it from the downstream end in the conveying direction. A lower conveyor capable of conveying each bag body to the opposite side of the conveying direction of the upper conveyor. A pair of the lower conveyors are provided in a horizontal direction orthogonal to the conveying direction, and the lower conveyors can approach and separate in a horizontal direction orthogonal to the conveying direction. The lower conveyors carry a predetermined amount of transport every time the bags fall from the upper conveyor so that each bag is displaced from the drop position in the transport direction, and a predetermined number of bags. When a predetermined number of linear bag groups connected to the lower conveyors are created, the lower conveyors are separated from each other so that the bag groups are aligned in the storage box. It is dropped and packed in a box.

Japanese Patent Laid-Open No. 2015-218023

  By the way, in the boxing apparatus of patent document 1, in order to make each bag body into the bag body group which aligns linearly, it is necessary to arrange two conveyors in parallel up and down. Therefore, there exists a problem that an installation will occupy a large space up and down.

  Further, in the apparatus as described above, when dropping the group of aligned bag bodies from the lower conveyors to the storage box, the approach and separation operation of the lower conveyors is performed while the bag bodies drop from the upper conveyor to the lower conveyor. It needs to be completed. However, in Patent Document 1, since each bag body falls from the upper conveyor to both lower conveyors at a constant short interval, both the lower conveyors are attempted to complete the approaching / separating operation during the dropping of each bag body. It is necessary to increase the speed of the approaching / separating operation of the lower conveyor, which not only increases the equipment cost, but also the approaching / separating operation by both the lower conveyors becomes intense, and the bag group is likely to be packed in a disordered state. There was also a problem.

  The present invention has been made in view of such a point, and an object of the present invention is to provide a low-cost and vertically compact packaging device that can package a bag group in a neatly arranged state. It is in.

  In order to achieve the above object, the present invention is characterized in that a bag group is created by damming each bag being conveyed by a conveyor every predetermined number of passages.

  Specifically, the following solution was taken for a boxing device configured to drop a plurality of bags into a container box opened upward and pack the boxes.

  That is, according to the first aspect of the present invention, the first conveyor that sequentially conveys the bag bodies by the circumferential movement operation of the first endless belt, and the predetermined number X passes of the bag bodies that are being conveyed by the first conveyor. Weiring means for sequentially transporting the bag body group by the first conveyor while repeatedly creating a linear group of bag bodies having a predetermined number X in the transport direction by damming, and the first conveyor A second conveyor that is provided on the downstream side in the conveying direction and above the storage box and that sequentially conveys each of the bag groups by a circular movement operation of a second endless belt, and the second conveyor is defined as a conveying direction. It is characterized by comprising bag drop means for dropping each bag group into the storage box by moving in an orthogonal horizontal direction.

  According to a second invention, in the first invention, the number detection means capable of detecting whether or not the number of bags of each of the bag groups conveyed by the second conveyor is X, and the number detection When the number detected by the number detection means is X, the bag fall means is controlled so that the second conveyor moves in a horizontal direction perpendicular to the transport direction. On the other hand, when the number detected by the number detection means is not X, the control means is configured to control the bag body dropping means.

  In 3rd invention, in said 1st or 2nd invention, a pair of said 2nd conveyor is juxtaposed in the horizontal direction which cross | intersects a conveyance direction, and both 2nd conveyors connect the said bag group to both said 2nd conveyors. The bag body dropping means is configured to move the second conveyors closer to and away from each other in a horizontal direction intersecting the transport direction.

  According to a fourth invention, in any one of the first to third inventions, the container box is reciprocated in a horizontal direction that is disposed below the second conveyor and intersects a conveying direction of the second conveyor. A box moving means is provided.

  According to a fifth invention, in any one of the first to fourth inventions, a plurality of the storage boxes or the storage boxes are vertically stacked on the second conveyor on the downstream side in the transport direction of the second conveyor. A box transporting means capable of transporting the stored storage box group along a transport path extending in the horizontal direction, and an upper position that is disposed upstream of the transport path and does not block the passage of the storage box in the transport path. A box holding means capable of holding the storage box or the storage box group, and disposed below the box holding means, and configured to be able to move up and down the storage box or the storage box group. A first box lifting and lowering means configured to be able to overlap the storage box or the storage box group in a state where the box is lifted and held by the box holding means, and is disposed downstream of the transport passage. Ascend the above storage box group It can be, and is characterized in that a second box elevating means capable of holding the container box group at a position above that does not block the passage of the receiving box group in the transport path.

  In the first invention, in the mechanism for dropping the bag body and storing it in the storage box, it is not necessary to arrange two conveyors above and below the storage box as in Patent Document 1, so that the compact packaging can be performed vertically. Can be a device. Moreover, when the bag body dropping means performs the dropping operation of the bag body, each bag body group created by the damming means is larger than the interval between the bag bodies before the bag body group is conveyed on the first conveyor. Since the interval becomes wider, the time until the next bag body group is dropped after dropping the bag body group from the second conveyor is compared with the case where each bag body is transported and dropped at a predetermined interval. become longer. Accordingly, since it is not necessary to make the operation of the bag body dropping means faster than necessary, the aligned bag bodies are not easily disturbed when dropped into the storage box, the equipment can be simplified, and the cost can be kept low. be able to.

  In the second invention, since the bag group is dropped only when a predetermined number of bag groups conveyed by the second conveyor are continuous, the accurate number of bag bodies are surely placed in the storage box. Can be accommodated. On the other hand, when the bag group conveyed by the second conveyor is not a predetermined number of bag bodies, the bag group passes through the upper side of the storage box as it is downstream of the second conveyor in the conveying direction. Therefore, the bag body group in which the bag bodies which are not a predetermined number are connected can be efficiently sorted and removed without reducing the operating speed of the equipment as much as possible.

  In 3rd invention, the stroke which moves a 2nd conveyor by a bag body dropping means can be shortened compared with the case where a bag body group is dropped by one 2nd conveyor. Therefore, the cycle time of the operation in the bag dropping means can be shortened as compared with the case where there is one second conveyor.

  In the fourth invention, the box moving means can reciprocate the storage box in the horizontal direction perpendicular to the transport direction of the second conveyor. It can be changed in the horizontal direction perpendicular to the transport direction. Therefore, each bag body can be stored in the storage box so that each bag body is arranged in a lattice shape with no gap when viewed from above.

  In the fifth invention, when a plurality of storage boxes are stacked by the box holding means and the first box lifting means, two storage box groups can be stacked by the second box lifting means adjacent to the box holding means. The storage boxes can be stacked efficiently and efficiently in two areas.

  When it is confirmed by each second bag body confirmation sensor 35b that the bag body group 10A composed of the four bag bodies 10 is conveyed by the second conveyors 33, as shown in FIGS. The circumferential movement of the second endless belt 33b is stopped while the plate 39a is in a position to dam the bag group 10A, and the second conveyor 33 is separated from each other by the bag dropping means 7 so that the bag group 10A is separated. It falls to the central part of the storage box 11.

  Next, as shown in FIG. 12, the second endless belt 33 b starts the revolving movement again, and both the second conveyors 33 approach each other by the bag dropping means 7 and are accommodated by the box moving unit 4. The box 11 moves from the position just below the bag drop unit 3 to the position retracted by the width of the bag 10. Then, when the bag group 10A conveyed by the second conveyors 33 is confirmed by the second bag confirmation sensors 35b, the second conveyors 33 are separated from each other by the bag dropping means 7, and the bag bodies are separated. The group 10 </ b> A falls on one end side portion of the storage box 11.

  Next, as shown in FIG. 13, both the second conveyors 33 approach each other by the bag body dropping means 7, and the storage box 11 is just below the bag body dropping unit 3 by the width of the bag body 10 by the box moving unit 4. Moves from the position to the advanced position. Then, when the bag group 10A conveyed by the second conveyors 33 is confirmed by the second bag confirmation sensors 35b, the second conveyors 33 are separated from each other by the bag dropping means 7, and the bag bodies are separated. The group 10 </ b> A falls on the other end side portion of the storage box 11.

  And the operation | movement which drops the bag group 10A from the bag body dropping unit 3 to the central part of the storage box 11, one end side part, and the other end side part in order, reciprocatingly moving the storage box 11 with the box moving unit 4. This is repeated once, and a total of 24 bags 10 are accommodated in the storage box 11 in a state where the bags 10 are aligned vertically and horizontally in a plan view and are stacked in two upper and lower stages.

  In addition, when the bag body group 10A consisting of the four bag bodies 10 is not carried into the second conveyors 33 of the bag body dropping unit 3, the bag bodies consisting of the four bag bodies 10 by the respective second bag body confirmation sensors 35b. It is confirmed that the group 10A is not conveyed by the second conveyors 33, and as shown in FIG. 14, the dam plate 39a rotates to the position where the dam of the bag group 10A is released, and the second conveyors The bags 33 are transported downstream in the transport direction without being separated from each other, and discharged to the outside of the bag body dropping unit 3 via the discharge slope 31a.

  When the bag 10 is spread over the storage box 11, the storage box 11 is moved to the region of the first box stacking mechanism 5 </ b> A of the box stacking unit 5 by the box moving unit 4 as shown in FIG. 2.

  When the storage box 11 moves to the area of the first box stacking mechanism 5A of the box stacking unit 5, as shown in FIGS. 15 and 16, both support members 53a are raised to support the storage box 11 from below. The position is raised to a position between both the box holding mechanisms 52. Then, the engaging claw 52b of each box holding mechanism 52 is switched to a horizontally extending posture and engages with each engaging hole 11a of the containing box 11 to hold the containing box 11 by the both box holding mechanism 52, and then both supports The member 53a is lowered.

  Next, as shown in FIGS. 17 and 18, when the next storage box 11 moves to the area of the first box stacking mechanism 5 </ b> A of the box stacking unit 5, both support members 53 a are lifted to move the storage box 11 downward. And is superposed on the storage box 11 held by the box holding mechanism 52 from below. At this time, each supporting claw 52b is switched to a posture in which each engaging claw 52b faces upward, and the support members 53a are moved until the storage boxes 11 on the lower side of the two storage boxes 11 stacked are positioned between the first box stacking mechanisms 5A. The two storage boxes 11 are further raised. Then, the engaging claws 52b of each box holding mechanism 52 are switched to a horizontally extending posture and engage with the respective engaging holes 11a of the lower receiving box 11 to hold the two receiving boxes 11 by the both box holding mechanisms 52. After that, both supporting members 53a are lowered.

  As described above, when a plurality of storage boxes 11 are stacked by the first box stacking mechanism 5A to obtain a storage box group 12A composed of a plurality of storage boxes 11, both support members 53a rise as shown in FIG. Then, the storage box group 12A is supported, and thereafter, the engagement claws 52b are switched to the upward posture, and the holding state of the storage box group 12A by the both-box holding mechanism 52 is released. Thereafter, both support members 53a are lowered to deliver the storage box group 12A to both the lift members 51c. Then, each slider 51b slides along each guide rail 51a, and the storage box group 12A moves to the area of the second box stacking mechanism 5B of the box stacking unit 5.

  When the storage box group 12A moves to the area of the second box stacking mechanism 5B of the box stacking unit 5, the storage box group 12A in a state where both the mounting plates 59 are supported by both the lifting members 51c as shown in FIG. And slide along the guide poles 56 to the side position.

  When both mounting plates 59 move to the side of the storage box group 12A, as shown in FIG. 21, the engagement claws 59c are switched to a horizontally extending posture, and each engagement of the storage box 11 at the bottom of the storage box group 12A. The second box lifting mechanism 58 is engaged with the hole 11a and holds the storage box group 12A.

  Next, as shown in FIG. 22, both mounting plates 59 slide upward to raise the storage box group 12A to an upper position that does not block the passage of the storage box group 12A in the transport path R1, and each slider 51b. Slides along the guide rails 51 a and the storage box group 12 </ b> B created next by the first box stacking mechanism 5 </ b> A enters between the side frames 55.

  Thereafter, both mounting plates 59 slide downward. Then, as shown in FIG. 23, the storage box group 12A is obtained by stacking the storage box group 12A on the storage box group 12B from above.

  Next, in a state where both the lifting members 51c support the storage box group 12, both the engaging claws 59c are switched to a posture of extending upward, and both the mounting plates 59 slide downward so that the respective engaging claws 59c of the storage box group 12 It moves to a position corresponding to the storage box 11 located on the bottom side. Thereafter, as shown in FIG. 24, each engaging claw 59c is switched to a horizontally extending posture, and each engaging claw 59c engages with each engaging hole 11a of the storage box 11, and both the second box lifting mechanisms 58 are moved. Holds the storage box group 12.

  Then, each slider 51b slides along each guide rail 51a to move both lifting members 51c to the region of the first box stacking mechanism 5A, and both mounting plates 59 slide downward, so that FIG. As shown, the storage box group 12 is placed on the carry-out guide portion 50. Thereafter, the worker carries out the storage box group 12 along the carry-out guide portion 50 to the downstream side in the transport direction, and the boxing operation is completed.

  As described above, according to the embodiment of the present invention, in the mechanism for dropping the bag body 10 and storing it in the storage box 11, it is not necessary to arrange two conveyors vertically above the storage box as in Patent Document 1. The boxing device 1 can be made compact in the vertical direction.

  In addition, when the bag body dropping unit 3 performs the dropping operation of the bag body 10, the first damming mechanism 28 causes the bag body 10 to move more than the interval between the bag bodies 10 before the bag body group 10 </ b> A is conveyed on the first conveyor 21. Since the interval between the created bag groups 10A is wider, the time until the next bag group 10A is dropped after the bag group 10A is dropped from both the second conveyors 33 is set for each bag 10. It becomes longer than the case of transporting and dropping at a predetermined interval. Therefore, since it is not necessary to make the operation of the bag drop unit 3 faster than necessary, the aligned bag groups 10A are less likely to be disturbed when dropped into the storage box 11, and the equipment can be simplified. Can be kept low.

  Further, since the bag group 10A is dropped only when a predetermined number of bag groups 10A conveyed by the second conveyor 33 are continuous, the correct number of bag bodies 10 are reliably stored in the storage box 11. Can be accommodated. On the other hand, when the bag group 10A conveyed by the second conveyor 33 is not the predetermined number of bag bodies 10, the bag group 10A is accommodated as it is downstream of the second conveyor 33 in the conveyance direction. Since the upper part of the box 11 is passed, the bag body group 10A in which the bag bodies 10 of a predetermined number are connected can be efficiently sorted and removed without reducing the operating speed of the equipment as much as possible.

  Further, the bag body dropping unit 3 is provided with a pair of second conveyors 33, and the bag body group 10A is dropped by moving the second conveyors 33 close to and away from each other. Thus, the stroke for moving each second conveyor 33 can be shortened compared to the case where the bag group 10A is dropped by one second conveyor 33. Therefore, the cycle time of the operation in the bag drop unit 3 can be shortened as compared with the case where there is one second conveyor 33.

  Further, since the box moving unit 4 can reciprocate the storage box 11 in the horizontal direction orthogonal to the transport direction of the second conveyor 33, the position where the bag group 10A is dropped relative to the storage box 11 is set to the second conveyor. It can be changed in the horizontal direction orthogonal to the conveying direction 33. Therefore, each bag body 10 can be stored in the storage box 11 so that each bag body 10 is arranged in a lattice shape without a gap when the storage box 11 is viewed from above.

  Further, when the plurality of storage boxes 11 are stacked by the box holding mechanism 52 and the first box lifting mechanism 53, the two storage box groups 12A and 12B are stacked by the second box lifting mechanism 58 adjacent to the box holding mechanism 52. Therefore, it is possible to efficiently stack the storage boxes 11 in two areas.

  In the embodiment of the present invention, a bag group 10A including four bag bodies 10 is created by the bag group creating unit 2, but a bag consisting of two or three bag bodies 10 is used. The body group 10 </ b> A may be created, or a bag group 10 </ b> A composed of five or more bag bodies 10 may be created.

  Further, in the embodiment of the present invention, the bag group creation unit 2 attaches four first bag body confirmation sensors 25 and detects whether or not four bag body groups 10A are connected. Not limited to this configuration, for example, when each bag 10 is aligned in a straight line, a desired number of bag groups 10A can be obtained by a sensor or the like configured to detect only the two rear bags 10. The structure which detects whether it is connected may be sufficient.

  In the embodiment of the present invention, when the bag body group 10A is dropped by the bag body dropping unit 3, the bag body group 10A is dammed by the second damming mechanism 39 and the second endless shapes of the second conveyors 33 are used. Although the circumferential movement operation of the belt 33b is stopped, either the damming operation by the second damming mechanism 39 or the stopping operation of the second endless belt 33b may be performed.
