Description

  The present invention relates to an automatic packaging method and apparatus for automatically packaging a plurality of saddle-stitched booklets stacked in a cube shape so as to fold kraft paper and cover at least four sides or all six sides of the cube except for both sides. .

  A plurality of stacked saddle-stitched booklets are packaged with a wrapping material such as strong kraft paper and shipped. A saddle-stitched booklet is a booklet in which stacked documents are bound and bound with a thick binder on the back, and the back of the binder is thicker than the contents, so when stacked, the back side becomes higher Therefore, “staggered wrapping” is usually performed so that the back part is evenly placed on both sides by reversing the direction every few books. However, the back part on both sides is still high after all. As shown, the center is in a low state.

An automatic packaging method and apparatus for ordinary books is described in Patent Document 1. First, this will be briefly described.
FIG. 11 is a perspective view showing the procedure of automatic packaging work for a stack of ordinary books. (A) is an article P to be packaged such as a stacked book. This is covered with a packaging material C from the upper surface as shown in FIG. Now, assuming the direction of lateral movement, the left is the front and the right is the rear. The covered packaging material C is longer than the packaged object P in both the front and the back, and hangs down below the bottom surface of the packaged product P. Moreover, both sides are projected outside the side surface of the article P to be packaged.

Next, as shown in (c), the rear hanging portion is folded back. Further, as shown in (d), the protruding portions on both sides on the rear side are folded back.
Subsequently, by moving the package P in the direction of the arrow while holding the front end of the front hanging part, the front hanging part is folded as shown in FIG. The bottom tape B is stuck and fixed, although it is not visible in this figure.

Next, as shown in (f), the protruding parts on both sides on the front side are folded back, and finally the parts protruding in the horizontal direction on both sides as shown in (g) and (h) are folded in the order of top and bottom. Then, fix the side tape S.
Although illustration of the apparatus is omitted, the article P to be packaged is placed on a lift table in a lowered state, and after the packaging material C is sent to the upper surface of the article P to be packaged, the lift table is raised while holding the upper surface. (B) in FIG. 11 described above, but at this time, the front end of the hanging portion is fixed by the lifted table. In this state, the push-back is pushed out from the right side to fold back the hanging part at the rear and to fold back the protruding parts on both sides. Subsequently, the folding of the forward hanging portion is performed by moving the article to be packaged P in the left direction with the tip fixed.

  Fig. 12 (a) is the final packaging of a normal stack of books, and Fig. 12 (b) is a perspective view with the bottom turned upside down, and C is craft paper or the like. Packaging material, S is a side tape for pressing the side of the folded packaging material on the small edge side, B is a bottom tape for pressing the overlapping portion of the packaging material on the bottom, and the side tape S and bottom tape B are, for example, a commercially available width of 50 mm Craft adhesive tape.

In normal books, the back portion and other portions have almost the same thickness, so that they are almost hexahedral when stacked, making it easy to wrap and the above-described wrapping method was possible.
However, as described above, a stack of saddle-stitched booklets is high on both sides, and the center is indented, so it is easy to collapse even when stacked. Since it is easy to slip, it is not possible to adopt a conventional packaging method in which it is lifted by a lift table in the middle of packaging. In other words, a packaging method that does not move up and down should be considered exclusively for saddle stitch booklets.

JP-A-2004-67104

Embodiments of the present invention will be described below with reference to the drawings.
Fig.10 (a) is a perspective view which shows the to-be packaged object P which piled up the saddle stitch booklet which is going to be packaged in this invention. In order to suppress the collapse of the cargo, the binding margins are stacked in the opposite direction for each appropriate number of books, and this is called “staggered packaging”. The small size a of the booklet ranges from 148 mm equivalent to A5 size to 240 mm including the shift allowance when A4 size is staggered, the top and bottom size b is 210 mm to 297 mm of A4 size, and the maximum height h of stacking is 220 mm And

FIG. 10B is a perspective view showing the final package of the package W after packaging, and the vertical and horizontal dimensions a ′ and b ′ are almost the same numerically because only the thickness of the wrapping paper is added. Absent. Only the height h ′ is compressed at the time of packaging, so the maximum is 80 mm.
For the packaging body W shown in FIG. 10 (b), a side tape is applied to the overlapping portion of the wrapping paper on the front and back sides of the figure, and an overlapping portion of the wrapping paper on the bottom surface that is not visible in the figure. The bottom tape is stuck and fixed. The tape used is, for example, the same commercially available craft adhesive tape as described above.

  FIG. 1 is a front view showing an automatic packaging apparatus according to an embodiment, FIG. 2 is a plan view, FIG. 3 is a left side view, and FIG. 4 is an explanatory diagram schematically showing FIG. This apparatus is designed so that the rack 1, the packaging material supply unit 2 for supplying kraft paper as a packaging material, the carry-in table 3 for carrying the stacked booklet P, and the stacked booklet (packaged material) that has been loaded are not destroyed. The surrounding lower frame 4, the upper frame 5, the package P, and the packaging material C are wound around, the roller table 6 that is conveyed downstream, the lateral folding mechanism 7 that folds the side packaging material, the packaged work W It is comprised by the carry-out table 8 etc. which carry out. As shown in FIG. 2, the worker is arranged beside the carry-in table 3, and 11 is an operation panel provided with buttons such as start and emergency stop.

  Among these, the carry-in table 3 and the carry-out table 8 are each provided with U-shaped cross-sectional guideways 31, 81 on which the workpiece slides and move, and pushers 32, 82 to move, especially with conventional packaging devices. There is no change. Moreover, the supply part of a packaging material and each tape is the same as what is used for general packaging equipment. The lateral folding mechanism 7 is the same as the conventional one described in Patent Document 1. Therefore, detailed description of these will be omitted, and hereinafter, description will be made centering on the operations from covering the top surface of the package with the packaging material, hanging down along both side surfaces, and folding the hanging portion down to the bottom surface.

  First, the movement of the workpiece will be described with reference to FIG. The operator stacks the booklets to a predetermined height, places the forehead portion back and forth on the carry-in table 3, and pushes it into the “load-in position” indicated by the thick line in FIG. 4 by the pusher. Here, the lower frame 4 stands by, and the article to be packaged is inserted therein, and the weight of the work is supported by the roller table 6. The packaging material is supplied to the upper surface of the article to be packaged, and then the upper frame 5 waiting upward is lowered, and the lower frame escapes downward in synchronization with pushing down the top surface of the article to be packaged by the press plate, Instead, the upper frame 5 holds the side surface of the workpiece. Then, the upper frame 5 moves laterally within the range indicated by the two-dot chain line in the figure, and during this time, the wrapping material that hangs down is folded to the bottom as described later, and then the side wrapping mechanism 7 wraps the side surface on the small edge side. The material is folded, a fixing tape is applied to the bottom and side surfaces, packaging is completed, and the material is unloaded from the unloading table 8.

Explaining the above procedure in more detail, as shown by an imaginary line in FIG. 3, an operator placed on the carry-in table 3 places an article to be packaged P on which a booklet is stacked on the guideway 31, and the pusher 32 uses the device. It is sent to the “loading position” in FIG. Here, the lower frame 4 rises and stands by, and the article P to be packaged is inserted inside the guide plate 42.
FIG. 5 is a perspective view of the lower frame 4. The lower frame 4 has a pair of guide plates 42 attached to both sides of the base plate 41 so as to face each other, and an engaging portion 43 that engages with the lifting mechanism 44 is provided at the base portion.

  Since the article to be packaged P is fed in the vertical direction, that is, the front end side is the front-rear direction, the distance between the guide plates 42 corresponds to the dimension a of the article P to be packaged in FIG. A stopper 45 is provided at the innermost position of the feeding so that the foremost object P stops at the optimal position for packaging. The stopper 45 is shown in FIG. The raising / lowering mechanism 44 can raise / lower the lower frame 4 linearly, for example by the combination of a raising / lowering cylinder and a linear guide. Thus, since the article P to be packaged is fed into the guide plate 42, no load collapse occurs at this point. As will be described later, when the upper frame 5 is lowered, the packaging material slides between the lower end portion of the upper frame 5 and the upper edge portion of the guide plate 42 of the lower frame 4. A good resin material 421 is attached.

  FIG. 6 is a perspective view showing the upper frame 5. The upper frame 5 is an inverted U-shaped upper folding frame 51 as viewed from the horizontal direction, a cylinder 511 for raising and lowering the upper folding frame 51, a horizontal press plate 52 inserted in a gap between the upper folding frame 51, and a cylinder 521 for raising and lowering this. The frame 5 includes a lateral feed mechanism 53 that moves the entire frame 5 in the lateral direction (left-right direction in FIG. 6). In FIG. 6, three rods can be seen in the cylinder 521, but the center is a cylinder rod and the two on both sides are guide rods. The transverse feed mechanism 53 is a normal transfer mechanism including a geared motor, a timing belt, etc., and is shown in FIGS. The distance between the left and right inner sides of the upper folding frame 51 is also the same as the distance between the guide plates 42 of the lower frame 4. The functions of the lower frame 4 and the upper frame 5 will be described later.

  The article P to be packaged sent into the load in the lower frame 4 is supported by a part of the roller table 6, that is, a part inside the lower frame 4. FIG. 7 is a front view showing the entire roller table 6, and the roller table is classified into five types: a first roller table 61 to a fifth roller table 65. The first to third roller tables 61 to 63 are mounted on a common moving frame 66 and can be moved laterally by a cylinder 661. The first roller table 61 is further moved on the moving frame 66 via a cylinder 611. The second roller table 62 can be moved laterally. Although the second roller table 62 is fixed to the moving frame 66, the third roller table 63 can be moved up and down on the moving frame 66 by the cylinder 631.

  The fourth roller table 64 can be opened and closed as indicated by an arrow by a cylinder 641 with the right end as a fulcrum. In any of the above, the roller itself is rotated freely and is not driven. The fifth table 65 is a simple plate-like fixed table. Among the above, the second roller table 62 and the third roller table 63 are located inside the lower frame 4 or the upper frame 5 in the “loading position”.

  Next, an automatic packaging method of the saddle stitch booklet in the embodiment of the present invention will be described with reference to the drawings. FIG. 8 is an explanatory view illustrating the first half of the automatic packaging method. (A) has shown the condition where the to-be-packaged goods P were sent from the carrying-in table 3 in the lower frame 4 in a "carry-in position". The packaged item P is supported by the second and third roller tables 62 and 63 and the both sides are sandwiched between the guide plates 42 of the lower frame 4 so that no load collapse occurs. In this state, the packaging material C is supplied. The roll of the packaging material supply unit 2 shown in FIG. 1 is rewound, and the packaging material C is fed to the upper surface of the article to be packaged P by the paper feed roll 21. At this time, since the packaging material C smoothly passes over the article to be packaged P, the shutter 22 that has been retracted on both sides advances and guides. When the packaging material C having a predetermined length is supplied, the rear end portion is cut by a shearing device (not shown).

  Next, as shown in (b), the upper frame 5 descends from above. While the press plate 52 presses the article P to be packaged via the packaging material C, the upper folding frame 51 continues to descend, and the lower frame guide plate 42 also descends in synchronization therewith. Since the packaging material C is pressed against the top surface of the article P to be packaged by the press plate 52, there is no displacement at this portion, and only the hanging portion on both sides is the gap between the upper folding frame 51 and the guide plate 42. And touch both sides of the package P.

  (C) shows a state in which the upper folding frame 51 is lowered almost to the bottom surface of the article P to be packaged, and (d) shows that the guide plate 42 of the lower frame is further lowered and the packaging material C is placed on both sides of the article P to be packaged. Shows the state of hanging. When the packaging material C is cut at the stage of (a), the sag of both sides in the state of (d) is not less than 1/2 of the small dimension a of the package P, and the dimension that overlaps when folded later. It is necessary to be.

  Next, as shown in (e), the first roller table 61 moves rightward and approaches the second roller table 62. Subsequently, when the first to third roller tables 61 to 63 on the common moving frame 66 are aligned and moved to the right, the rollers do not rotate and the workpiece does not move. As shown, only the sagging portion of the packaging material C is in a state of fluttering to the right. Since the third roller table 63 comes out of the lower part of the article to be packaged P, the support of the object to be packaged P is replaced by the first roller table 61 and the second roller table 62.

Next, the explanation will move to the explanation of FIG. 9, which is the latter half of the automatic packaging method. As shown in (g), the third roller table 63 released from the support of the article to be packaged P is lowered, and the fourth roller table 64 that has been opened upward is closed and overlapped therewith. The right hanging portion of the packaging material C between the three roller tables 63 is sandwiched.
Subsequently, the lateral movement of the work (packaged object) P is started. 1 and 2, the entire upper frame 5 is laterally moved in the right direction, and the work P surrounded by the upper frame 5 is also moved while sliding on the roller table. However, since the position of the roller table itself does not change, only the workpiece P moves while the tip of the packaging material C is held between the lower roller tables 63 and 64 as shown in FIG. As shown in (i), the packaging material C at the bottom is overlapped with each other. In this state, the bottom tape is pasted by the bottom tape pasting means 67 provided on the fifth roller table 65 or a subsequent portion, and the entire circumference packaging is completed.

In the case of four-sided packaging, all of the packaging work is completed. In the case of six-sided packaging, the side folding mechanism 7 subsequently folds both side surfaces, and the side surface tape attaching means 71 uses the side surface tape S. It is necessary to fix.
As is clear from the above description, the work sent to the “loading position” is initially sandwiched on both sides of the guide plate 42 of the lower frame 4, and then the upper folding frame 51 of the upper frame 5 is lowered. Instead of this, both sides are restrained and the restraint continues until the bottom fold is fixed. Further, since the workpiece is not moved in the vertical direction during the packaging, the stacking of the saddle-stitched booklets is not broken in the present invention.

  If the size of the booklet to be handled changes, the interval between the guide plate 42 and the upper folding frame 51 and the number of rollers of the roller table 6 must be changed. Omitted.
