Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automatic boxing device and its pushing device. More specifically, the present invention relates to an automatic boxing device for aligning bag-packed products and boxed products and automatically storing them in an outer box such as a larger cardboard case, and a pushing device suitable for the automatic boxing device. .
[0002]
[Prior art]
FIG. 9 shows such a conventional automatic boxing apparatus. FIG. 9A is a schematic front view of the apparatus, and FIG. 9B is a plan view thereof. As shown, this apparatus includes an introduction conveyor 51 for supplying articles W to be boxed, an alignment conveyor 52 for receiving and aligning a plurality of articles W supplied from the introduction conveyor 51, and an aligned group of articles. An extrusion plate 53 for taking out from the alignment conveyor 52 as it is, and a push-in device 55 for pushing down the taken-out article group as it is and inserting it into the outer packaging box below (similarly). (For example, refer to Patent Document 1). This push-in device 55 has a holding plate 54 that holds and holds the taken-out article group in an aligned state until just before pushing it in.
[0003]
As shown in FIG. 9B, the aligning conveyor 52 has a plurality of fins 57 mounted on the transport surface of an endless track 56 in parallel with each other at a predetermined interval in the transport direction. This predetermined interval is dimensioned so that one article W can be accommodated, and is called a gap portion 58. Endless orbits are divided into two parallel groups. A first group 56a composed of a first belt and a third belt, and a second group 56b composed of a second belt and a fourth belt. In the first group 56a, the fin group is attached so as to straddle the first belt and the third belt, and in the second group 56b, the fin group is attached so as to straddle the second belt and the fourth belt. . The groups 56a and 56b are circulated and driven independently from each other by different driving devices.
[0004]
The endless track 56 is arcuate in the sprocket 52a portion from the lower return path to the upper outbound path, and the plurality of fins 57 spread radially. This portion of the aligning conveyor 52 becomes a receiving position R for receiving the article W from the introducing conveyor 51 (FIGS. 5 and 6 of Patent Document 1). When the first group 56a of the endless track described above is stopped at the receiving position R, the second group 56b can be moved, or can be stopped at an article take-out position T described later. On the other hand, when the second group 56b is stopped at the receiving position R, the first group 56a can be moved or stopped at the article take-out position T.
[0005]
A belt conveyor or a roller conveyor is used as the introduction conveyor 51, and the discharge end 51a faces the receiving position R. The supplied articles W fall one by one from the discharge end 51a of the introduction conveyor 51, and the alignment conveyor 52 receives the articles W one by one in each gap portion 58 while moving by one gap. When the articles W enter all the gap portions 58, the alignment conveyor 52 moves to the article take-out position T at a stretch. The article take-out position T is located in an outward path in which the endless track 56 is in a horizontal state and the fins 57 stand upright, and the push-out plate 53 pushes the articles W of the gap portions 58 together from the endless track 56. Position.
[0006]
At the article take-out position T, the push-out plate 53 moves horizontally so as to cross the alignment conveyor 52 and pushes out all articles from between the fins. The extrusion plate 53 is formed with slits (not shown) through which the fins 57 can pass. The article W is transferred to the pushing device 55 by the pushing plate 53 in the aligned state. The pushing device 55 includes an opening / closing shutter (hereinafter simply referred to as a shutter) 60 on which an article transferred by the pushing plate 53 is placed, a pushing plate 61 for pushing the article downward, and a carry-in / out position of the outer box C And a lifter 62 that moves up and down between the insertion position where the article is inserted.
[0007]
The article group transferred by the extrusion plate 53 is stopped by the stopper plate 63 when reaching the opening / closing shutter 60, and is held by the holding plate 54 here. Below the shutter 60, the lifter 62 on which the outer box C is placed is disposed.
[0008]
As shown in FIG. 10, the shutter 60 is composed of a pair of plate members that are opened and closed by approaching and separating in the horizontal direction. A frame member (an attachment member for attaching a guide member described later) 65 in which a rectangular opening 64 through which the article group W and the push-in plate 61 can pass is provided in the vicinity of the shutter 60 and below the shutter 60. . A rectangular frame-shaped guide member 66 is attached to the periphery of the opening 64, and each side of the guide member 66 is composed of a plate member that is inclined downward toward the inside of the opening (see FIG. 1). 1-4). The guide member 66 is for preventing the article W pushed downward from being caught on the flap (lid) F of the outer box C. This flap F is a well-known one extending continuously upward on each of the four sides of the upper surface of a general corrugated cardboard case. These flaps F are finally folded inward and bonded together with gum tape or the like and closed. It is what When the outer box C is at a position below the opening 64, the flap F is opened and stands upward, and the outer casing C is positioned so that the lower end of the guide member 66 is positioned inside each flap F.
[0009]
Next, when the shutter 60 is fully opened and the holding plate 54 releases the holding of the article, the pushing plate 61 descends almost simultaneously and pushes the article group into the outer box C. Since the article enters the outer box C while being guided by the guide member 66, the end of the article W is prevented from being caught by the flap F.
[0010]
However, since the guide member 66 has a rectangular frame shape with four sides integrated, if the outer box C is changed to a different size, it is necessary to replace the guide member 66 with a different guide member accordingly. In addition, the outer box such as a cardboard case has a large dimensional error of the product, and there are many cases in which the flap is slightly tilted inward. In these cases, the guide member 66 may not enter the inside of the flap well, and the function as the guide member cannot be exhibited.
[0011]

Japanese Patent Laid-Open No. 2002-19707
[Problems to be solved by the invention]
The present invention has been made to solve such a problem, and when the article is pushed into the outer packaging box having the flap in a standing state from above, the flap is eliminated from the descending path of the article and is effective without being caught. An object of the present invention is to provide an automatic boxing device capable of guiding and packing an article group in an outer box and a pushing device for the automatic boxing device.
[0013]
[Means for Solving the Problems]
The pushing device for the automatic boxing device of the present invention is:
A pushing device for inserting an article into a storage case from above,
A pair of shutters that are opened and closed by moving closer to and away from each other in the horizontal direction, on which the article is placed;
A pushing member for pushing the article on the shutter downward;
An opening member disposed below the shutter and having an opening through which the article and the pushing member can pass;
An elevating device disposed below the opening member for raising the housing case to just below the opening;
And a flap opener extending downward from the mutually facing edges of the shutters through the opening.
[0014]
According to this configuration, when the shutter is opened, the flap opener moves together with the shutter. Therefore, when there is a storage case with a flap standing immediately below the opening, when the shutter reaches the fully open position, the flap (a so-called minor flap, the flap positioned at the end of the shutter opening direction) is opened by the flap opener. Retained. Moreover, since the pair of shutters moves integrally with the flap opener in the opening direction, the housing case is also positioned. Further, when the article is lowered (dropped), the flap opener also serves as a guide.
[0015]
The opening has a rectangular shape, and of the four sides of the opening member, the members constituting two sides parallel to the opening / closing direction of the shutter are configured to be able to advance and retreat in a direction perpendicular to the opening / closing direction of the shutter. The device is like this. This is because the size of the opening can be changed according to the housing case by changing the position of the member together with the opening of the shutter.
[0016]
A pushing device in which the opening has a rectangular shape and a flexible guide plate that is inclined toward the inner side of the opening is attached to two sides parallel to the opening / closing direction of the shutter among the four sides of the opening is preferable. This is because the guide plate can prevent the article from being caught on the lid of the storage case when the article falls.
[0017]
In addition, the left and right ends of the flap opener are located close to the guide plates on the two sides of the opening, and are inclined toward the lower side on the inside of the opening at both ends of the other two sides orthogonal to the two sides of the opening. A pushing device to which a flexible guide plate is attached is preferable. This is because the guide plate can more effectively prevent the article from being caught by the lid of the storage case when the article falls.
[0018]
A pushing device in which the left and right edges of each flap opener are inclined inwardly downward and the length of the upper edge of the flap opener is made larger than the width of the housing case is preferable. This is because the major flap (the flap in the direction perpendicular to the minor flap) of the housing case can be opened by the left and right sides of the flap opener.
[0019]
A pushing device in which the left and right end edges of the flap opener are close to the guide plates on the two sides of the opening and formed obliquely so as to correspond to the inclination of the guide plate is preferable.
[0020]
A pushing device in which a side flap opener extending in the shutter closing direction is formed on the left end edge of one flap opener and the right end edge of the other flap opener is preferable. This is because the side flap opener can stably maintain the opened state of the major flap even when the shutter is fully opened.
[0021]
A pushing device in which the side flap opener is formed so as to be continuously curved and extend in the shutter closing direction from the end edge of the flap opener is preferable. This is because the manufacturing is easy and the friction with the guide plate and the flap is reduced.
[0022]
The automatic boxing device of the present invention is
A transport apparatus provided with a storage unit for storing articles;
An article supply device arranged to face the article receiving position arranged in the conveying device;
Any one of the aforementioned article pushing devices;
An article push-out device that takes out an article from an article take-out position arranged in the carrier device and conveys the article to the article push-in device.
[0023]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of an automatic boxing device of the present invention will be described with reference to the accompanying drawings.
[0024]
FIG. 1 is a front view of an automatic boxing apparatus according to an embodiment of the present invention. 2 is a plan view of FIG. 1, and FIG. 3 is a view taken along the line III-III of FIG.
[0025]
The illustrated automatic boxing device (hereinafter simply referred to as “device 1”) 1 includes a loading device 2 for aligning the articles W and automatically storing them in an outer box C such as a cardboard case, etc. Are provided, a box carrying-in conveyor 4 for carrying the outer box C into the loading device 2, and a box carrying-out path 5 for carrying out the outer box C in which articles are stored by the loading device 2. As the introduction conveyor 3 and the box carry-in conveyor 4, a belt conveyor or a roller conveyor is used. The box carry-out path 5 is a free roller type in which a large number of rollers that are not normally driven to rotate are only rotatably mounted, but a belt conveyor or a roller conveyor may be used.
[0026]
The loading device 2 receives a plurality of articles W supplied from the introduction conveyor 3 and aligns them with an alignment conveyor (conveying device) 6 and an extrusion for taking out the aligned articles in the horizontal direction. A plate 7, a pair of holding plates 8 that hold the picked-up article group as it is and temporarily hold it, and for inserting the picked-up article group into the outer packaging box C below A pushing device 9 is incorporated.
[0027]
As shown in FIG. 4, the alignment conveyor 6 has the same configuration as that already described as the prior art. In other words, it has an endless track 16 composed of a first group of belts 16a and a second group of belts 16b that are parallel to each other. A plurality of fins 10 are attached to the belt groups 16a and 16b in parallel to each other at a predetermined interval (referred to as a gap portion 11) as an article accommodating portion in the conveyance direction on the conveyance surface. A plurality of fin groups are arranged at predetermined intervals in the conveying direction of the endless track 16. In the first group 16a, the fin group is attached so as to straddle the first belt and the third belt, and in the second group 16b, the fin group is attached so as to straddle the second belt and the fourth belt. The belts of the groups 16a and 16b are circulated and driven independently from each other by different driving devices.
[0028]
The endless track 16 circulates and stops when each fin group sequentially reaches an article receiving position R and an article taking-out position T described later. In the portion of the sprocket 6a from the lower return path of the endless track 16 to the upper forward path, the endless track 16 has an arc shape, so that the plurality of fins 10 spread radially. A part of the portion of the alignment conveyor 6 where the fins 10 spread radially is a reception position R for receiving the articles W, and the article discharge end 3a of the introduction conveyor 3 faces the reception position R. Articles fall one by one from the discharge end 3a of the introduction conveyor 3, and enter the gap portions 11 one by one. The alignment conveyor 6 moves by one gap when receiving the articles W, and each gap 11 stops at the receiving position R sequentially. When the articles W enter all the gap portions 11 in this way, the alignment conveyor 6 is driven and the fin group is moved to the article take-out position T at a stretch.
[0029]
At the article take-out position T, the push-out plate 7 moves horizontally so as to cross the alignment conveyor 6 and pushes out all articles W from between the fins. The extrusion plate 7 is formed with slits 12 through which the fins 10 can pass so as not to interfere with the fins 10 when crossing the alignment conveyor 6. All articles W are transferred to the pushing device 9 by the pushing plate 7 in the aligned state.
[0030]
The pushing device 9 has the same configuration as that already described as the prior art. That is, the holding plate 8, the opening / closing shutter 13 on which the article transferred by the extrusion plate 7 is placed, the pushing plate 14 for pushing the article downward, the carry-in / out position of the outer box C, and the outer box C Includes a lifter 15 that moves up and down between a waiting position for waiting for the insertion of an article, and a stopper plate 17 for abutting the article group W transferred by the extrusion plate 7 and positioning in the transfer direction. The shutter 13 is composed of a pair of plates that are installed in a horizontal state and that open and close by being moved away from each other in the horizontal direction.
[0031]
The standby position is changed and set according to the height dimension of the outer box C. The height dimension of the outer box C means that the outer box C is opened with its lid (referred to as a flap) like a cardboard box, that is, with the flap F standing up and waiting, The dimension from the bottom to the top of the flap. The carry-in / out position is at the same level as the box carry-in conveyor 4 and the box carry-out path 5.
[0032]
As shown in FIGS. 1, 3, 5, and 6, an opening member 19 is installed near the shutter 13 and below the shutter 13. A rectangular opening 18 through which the article group W and the push-in plate 14 can pass through the opening member 19 and the edge part 13a (the edge part that abuts when closed) 13a facing each other. Is configured. Therefore, the shutter 13 opens and closes the opening 18.
[0033]
As shown in FIGS. 5 and 6, the opening member 19 is a member extending in parallel with the opening / closing direction of the shutter 13, and has a deformed L shape with a sharp cross section (see FIG. 5C). The opening member 19 is driven back and forth in a direction perpendicular to the opening / closing direction of the shutter 13. That is, the width of the opening 18 can be changed according to the width of the article W (the width of the exterior box C). As the drive device for the frame member 19, a known device such as a feed screw mechanism 20 using a ball screw can be adopted. Along with the setting change of the opening degree of the shutter, the size of the substantial opening 18 can be changed according to the size of the exterior box C by changing the position of the frame member 19.
[0034]
Further, a drive device (not shown) for the extrusion plate 7, an opening / closing drive device (not shown) for the shutter 13, a lift drive device (not shown) for the push plate 14, and a lift drive device 15a for the lifter 15 (FIG. 1 and FIG. 1). 3) and the drive device 20 of the frame member 19 use servo motors, respectively, so that position control can be easily performed.
[0035]
As shown in FIG. 6B, the pair of holding plates 8 are respectively disposed above the shutter 13 and on both ends in the opening / closing direction of the shutter 13. When the holding plate 8 clamps the group of articles conveyed to the top of the shutter 13, the pair of holding plates 8 approach each other in the shutter closing direction. The outer packaging box C waiting below the shutter 13 is waiting at a position where the upper end (the upper end of the flap in the case of a cardboard box with a flap) is close to the lower surface of the shutter 13.
[0036]
When the article group is packed in the lower exterior box C, after the push plate 14 is lowered and the article group W sandwiched between the holding plates 8 is slightly pressed from above, the shutter 13 opens and the holding plate 8 Move in the direction to release the holding of the group W. As a result, the article group W starts to fall after the pushing plate 14 is accelerated, so that the article group W can be prevented from moving downward from the pushing plate 14. The pushing plate 14 descends at a speed slightly faster than the free fall speed. The article group W receives a frictional resistance from the holding plate 8 at the beginning, and then descends while receiving a frictional resistance from the inner surface of the outer box C (or the raised flap).
[0037]
A flap opener 21 is extended from each of the opposite edge portions 13a of the pair of shutters 13 so as to pass through the opening 18 vertically downward therefrom. The flap opener 21 is detachably attached to the shutter 13 with a bolt or the like. Further, the flap opener 21 is for holding the minor flaps (flaps located at both ends in the opening / closing direction of the shutter) Fma of the exterior box C waiting in the downward direction. Formed from. Since the end edge portion 13a is linear in a direction perpendicular to the opening / closing direction of the shutter 13, the flap opener 21 is perpendicular to the opening / closing direction of the shutter 13 and forms a vertical surface. The flap opener 21 also has an effect of guiding the fall of the article W as will be described later.
[0038]
On the other hand, a flexible guide plate 22 inclined downward toward the inside of the opening 18 is detachably attached to the frame member 19 that forms two sides parallel to the opening / closing direction of the shutter 13 among the four sides of the opening 18. It is attached. Therefore, the lower end of the guide plate 22 enters the opening more than the frame member 19. The guide plate 22 guides the fall of the article W. And, since it enters the inside of the major flaps (flaps located on both sides in the direction perpendicular to the minor flaps in the present embodiment) Fmj of the outer packaging box C waiting below, the role of holding the major flaps Fmj in the open state Fulfill. Therefore, the flap opener 21 is positioned so as to enter the opening of the guide plate from the frame member 19 to the inside of the opening so that both side ends thereof do not contact the guide plate 22. That is, the lateral width (the length in the direction perpendicular to the opening / closing direction of the shutter 12) is narrower than the lateral width of the opening 18.
[0039]
Further, as shown in FIGS. 5 and 6, a flexible guide that is inclined downward toward the inside of the opening 18 at positions corresponding to both side ends of the flap opener 21 when the shutter is fully opened in the opening member 19. A piece 25 is attached. In this case, when the shutter 13 is fully opened, the portions outside the flap opener 21 on the vertical side of the opening 18 are exposed, and thus this portion is also provided with guidance. The guide piece 25 has flexibility and is inclined downward toward the inside of the opening 18. The guide piece 25 has the same configuration as the guide plate 22 described above, but its length is different (short).
[0040]
When the shutter 13 is opened, the flap opener 21 stops in a state in which the minor flap Fma of the outer box C is pushed open, so that the outer box C on the lifter 15 is positioned. Further, since the minor flap Fma is pushed open, it also serves to guide the fall of the article W.
[0041]
7 and 8 show another flap opener 23. The flap opener 23 has both end edges 23a inclined inwardly downward. In other words, the width is narrowed downward. The inclination of each end edge 23a substantially corresponds to the inclination of the guide plate 22 described above. Further, a side flap opener 24 extending in the closing direction of the shutter 13 (perpendicular to the surface of the flap opener 23 and facing the opposing flap opener) is formed on one of the inclined edges 23a. The side flap opener 24 is for holding the major flap Fmj of the outer box C in an open state. The surface of the side flap opener 24 is inclined corresponding to the surface of the opposing guide plate 22.
[0042]
Therefore, when the outer box C with the flaps raised is raised by the lifter 15, the major flap Fmj is regulated by the side flap opener 24, so that the major flap Fmj is kept open and the outer box C Vertical positioning is performed. For this reason, the width of the upper end of the flap opener 23 is preferably larger than the width of the outer box C, and the width of the lower end is preferably smaller than the width of the outer box C.
[0043]
As shown in the figure, the edge where the side flap opener 24 is formed is the right edge (right side in the figure) of the flap opener 23 (front side in FIG. 7) when the flap opener 23 is attached to the shutter 13. The flap opener 23 on the other side (the front side in FIG. 7) is formed at a left end edge (left side in the figure) that is not opposed to each other. And each side flap opener 24 is formed so that it may be located in the outer side of the edge 23a so that it may not interfere with the opposing flap opener 23 so that both the shutters 13 can be fully closed (refer Fig.8 (a)). ). Further, since the side flap opener 24 extends in the closing direction of the shutter 13, the major flap Fmj is kept open even when the shutter 13 is fully opened.
[0044]
The side flap opener 24 is formed as a single piece continuous from the edge of the flap opener 23 by curving the end of the flap opener 23. As a result, not only manufacturing is easy, but also friction between the guide plate 22 and the major flap Fmj is reduced when the shutter 13 is opened and closed.
[0045]
Thus, since the side flap opener 24 can hold the major flap Fmj in the open state, the guide plate 22 may be removed.
[0046]
【The invention's effect】
According to the present invention, when an article is pushed into an exterior box or the like from above, the article can be prevented from being caught on the lid or the like of the exterior box. Furthermore, the outer box can be positioned.
