Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a forming and feeding device for a member to be interposed which is interposed between a plurality of articles arranged in a container in an aligned manner.

Conventional technology For example, a carton blank of corrugated cardboard sheets, such as a corrugated cardboard case, is boxed in a three-dimensional container, and a plurality of bottles, cans, and other various boxed products are arranged in the container in an aligned manner, and then packed. In a machine, it is generally practiced to interpose a partition, subdivision, or other cushioning plate material between a plurality of adjacent articles stored in the three-dimensional container. As the intervening member, a flat plate material made of corrugated cardboard or cardboard is used alone, and the intervening member is dropped into the adjacent space between the articles intermittently transferred during the packaging process. The supply method is usually adopted. Further, a method in which the member to be interposed is constituted by combining a plurality of flat plate members in a cross beam shape and the article is supplied between the meshes of the interposed member formed in the cross beam shape is also appropriately adopted.

By the way, in the various members to be interposed, as shown in FIG. 1, the flap is bent outward in a U shape and is folded back at a horizontal bottom portion to have an H shape as a whole. There are special forms. As shown in FIG. 2, the articles 10 are individually stored in a container box for each unit, and the H-shaped member 1 to be interposed 1 is provided between the articles 10 adjacent to each other.
A plurality of articles are put together into one package with two intervening pieces, and the pieces are individually separated by breaking along the tear line 16 engraved on the lid of the outer box body 14 as necessary. It is preferably used for a so-called collective packaging box which can be divided into the above packaging boxes.

SUMMARY OF THE INVENTION However, the H-shaped member to be interposed has a special shape having a large number of bent portions as described above,
It has heretofore been realized to integrally incorporate a device for bending and forming an intervening member and automatically supplying an article to a group of articles into a device for automatically box-making and boxing like the corrugated cardboard caser. There wasn't.

SUMMARY OF THE INVENTION In view of the above-mentioned present situation, the present invention bends an H-shaped member to be interposed from a blank made of a flat plate material, and supplies the member to be interposed between a plurality of articles. The present invention proposes a molding and feeding device of the above, with the purpose of enabling the automatic feeding of the members to be fed into a feeding article group in a fully automatic box making and boxing machine such as a rewrap round caser. To do.

Means for Solving the Problems In order to achieve the above-mentioned object, a forming and feeding device for an interposed member in a packing machine according to the present invention is provided with two flap forming folds parallel to a flat plate material, A folding fold is formed at an intermediate position of the fold at a right angle to the fold, and a predetermined number of blanks in which a folding line is formed at a portion where the folding fold comes into contact with the flap are stacked and stored. Hopper, a suction member that is arranged below the hopper so as to be able to move up and down, and takes out the blanks of the hopper from the lowermost one by one downward, and the blank bending forming in which the taken-out blanks are provided on the side of the hopper. A feeding means having a transfer member for laterally transferring to a position, and arranged so as to be able to move up and down so as to face each other on both sides in the extending direction of the folding fold that sandwiches the blank horizontally supported at the blank bending position. When it descends, it abuts against the flaps on both sides of the cutting line and bends the flap outwards at a substantially right angle along the folds for flap formation, and the folds for abutment to bring the blank into contact with the folds. A pair of flap folding means integrally provided with an auxiliary member forcibly folded back and a swingable arrangement on both sides sandwiching the folding fold below the blank horizontally supported at the blank bending position. Two pairs of folding plates, which are installed and can be changed from a posture of expanding upwards to a palm posture of approaching in a substantially vertical direction, are provided in two sets spaced apart in the extending direction of the folding folds, and when the flap folding means descends. Blank folding means for folding the blank folded back by the auxiliary member back to back along the folding fold toward the upper side when the folding plate changes from the expanded posture to the palm-folding posture, and the blank folding. Corresponding to the folding folds of the blank that is supported horizontally in the forming position, it is located between the pair of flap folding means, a standby position above the blank folding forming position, and an operation below the blank folding means. The blank folding means is arranged so as to be able to move up and down between the position and the position, and when it descends from the standby position to the operating position, it abuts against the upper end of the bending-shaped H-shaped member to be interposed and pushes it down. And a push-down member forcibly supplying the member to be interposed between a plurality of articles positioned below the.

EXAMPLES Next, the apparatus for forming and supplying the interposed member in the packing machine according to the present invention will be described in detail below with reference to preferred examples. FIG. 3 shows an outline of a step of forming a special intervening member 12 having the H-shape shown in FIG. 1. The intervening member 12 is a flat plate made of, for example, a corrugated cardboard sheet or a cardboard. Blank 2 punched out from a rectangular plate
6 is used as the material (the blank 26 may be square). This blank 26 is parallel to its longitudinal direction by 2
Flap-forming folds 18, 18 of the strip are engraved, and one fold 20 for folding back the blank is engraved at an intermediate position of the folds 18, 18 at right angles to the fold. A cut line 24 is formed at a portion where the blank folding back fold 20 comes into contact with the flaps 22, 22. The cutting line 24 may be a slit having a narrow width, or may be a single line of cutting line. The blank 26 thus formed by punching or other means is bent by a forming and feeding device as described later to be formed into the H-shaped member 12 to be interposed.

The molding supply device according to the embodiment is shown in FIGS. 4 to 9.
This device performs a required operation to bend the blank 26 into a predetermined shape and form it as an H-shaped interposed member 12 during a series of steps. FIG. 5 is a schematic side view of the apparatus, FIG. 5 is a schematic view taken along the line VV of FIG. 4, FIG. 6 is a schematic view taken along the line VI-VI of FIG. 4, and FIG. FIG. 7 is a schematic plan view seen from the direction of the line VII-VII. Also, in FIG.
The details of viewing the device in the figure from the left are disclosed. And this device is arranged at an appropriate position of a boxing machine for fully automatic box making and boxing.

In the schematic view of the apparatus shown in FIG. 4, a mechanism for storing and supplying the blank 26 is disclosed on the right side thereof, and a mechanism for folding the blank and forcibly supplying the blank downward is disclosed on the left side of the mechanism. Is substantially disclosed. That is, in FIG. 4, reference numeral 28 indicates a hopper, and a predetermined number of the blanks 26 are horizontally stacked and stored in the hopper 28. This hopper 2
The lower portion of the blank 26 is opened entirely, and rollers 30 are rotatably pivoted at the four corners thereof, and the corner portions of the blank 26 are placed on the four rollers 30 in contact with each other. .

Below the hopper 28, a blank withdrawing mechanism 32 is arranged to take out the blanks 26 one by one up to a predetermined level below. The blank pulling-down mechanism 32 is basically composed of a vacuum suction cup 34 and a double-acting air cylinder 36 for vertically moving the vacuum suction cup 34. The vacuum suction cups 34 are correspondingly attached to the upper four corners of a base 38 forming a rectangular frame in a plan view, with their suction surfaces directed upward, respectively. Connected to a vacuum suction source via a flexible hose. A guide rail 40 is vertically fixed below the base 38, and the guide rail 40 is rotatably attached to a vertical support base 43 (which is attached to a device base frame via a bracket 42). Both sides are slidably sandwiched by a pair of upper and lower guide rollers 44 arranged. Further, the air cylinder 36 is attached to the vertical support base 43 via a clevis 46, and the piston rod 48 of the air cylinder 36 is vertically upwardly and vertically movable, and the tip of the piston rod 48. Is pin-connected to the guide rail 40. Therefore, when the air cylinder 36 is biased by pressure, the piston rod 48 vertically rises by a predetermined stroke, whereby the base 38 and the vacuum suction cup 34 attached thereto rises to be positioned at the lowermost surface of the hopper 28. Abutting the bottom of the blank 26. It will be appreciated that the vacuum suction cup 34 is then actuated by vacuum suction and the air cylinder 36 is reversely biased to pull the vacuum suction cup 34 down to a predetermined level while holding the blank 26. When the blank 26 descends by a predetermined level in this manner, as shown in FIG. 8, the blank 26 is formed at each angle portion of the rails 50, 50 having an L-shaped cross section and arranged in parallel at a predetermined interval. Both ends are abutted against each other and held at a horizontal level. At this timing, the vacuum suction of the vacuum suction cup 34 is also released.

Next, also in FIG. 4, a long air cylinder 54 is arranged along the vertical support column 52, and the piston rod 55 thereof is directed vertically upward. A rack 56 made of a long member is fixed to the tip of the piston rod 55, and the rack 56 meshes with a pinion 58 rotatably supported at a required position above the rack 56. A large-diameter sprocket 60 is connected and fixed to the pinion 58 with its rotation axis being common, and the chain 6 is attached to the sprocket 60 and a small-diameter sprocket group 62 scattered and arranged at appropriate positions as shown in FIG.
4 is wound so that it can run. A kicker 66 for fixing the rear end of the blank 26, which is stationary at a predetermined position below the hopper 28, and sending it out to the left (in FIG. 4), is fixed to the chain 64. It travels back and forth in the horizontal traveling area of the chain 64. As shown in FIG. 4, when the blank 26 is waiting to be folded, the piston rod 55 retracts into the double-acting air cylinder 54, and the rack 56 stands still at the lowest position. At this time, the kicker 66 is in a solid line position where the blank 26 is pushed out to the middle (blank bending position) of a blank folding mechanism (left side in FIG. 4) which will be described later and is in contact with the rear end portion. In this state, the air cylinder 54 is urged to press the piston rod 55.
Is extended, the rack 56 meshes with the pinion 58 and ascends to rotate the pinion 58 clockwise. Therefore, the sprocket 60 also rotates in the same direction, and drives and runs the chain 64 to bring the kicker 66 to the right end in FIG. 4, that is, to the position of the broken line right below the hopper 28 and stop.

Here, the operation order of each member driven by the two double-acting air cylinders 36 and 54 is summarized as follows. That is, the vacuum suction cup 34 is lifted by the biasing of the air cylinder 36 to vacuum-suck the blank 26, and then the blank 26 is pulled by the cup 34 by the reverse biasing of the air cylinder 36 so that the blank 26 is removed from the hopper 28
The L-shaped rails 50, 5 are taken out downward one by one toward the sheet.
0 is transferred horizontally. At this time, the kicker 66 stands by at the position of the broken line shown in FIG. 4, and catches the timing when the transfer of the blank 26 is completed, and the other air cylinder 5
4 is biased to drive the chain 64 under the meshing action of the rack 56 and the pinion 58 as previously described. As a result, the kicker 66 runs horizontally to the left in FIG. 1, hooks the lower end of the blank 26 located below the hopper 28 as described above, pushes it out to the left for a predetermined stroke, and then stops. . Ie blank 26
Will be horizontally transferred to the intermediate portion of the blank folding mechanism provided above the article standby position as shown by the solid line in FIG. Next, the air cylinder 54 is reversely urged, and the kicker 66 retreats to the position indicated by the broken line to wait for the next blank 26 to be supplied.

Next, details of the blank folding mechanism disclosed on the left side of FIG. 4 will be described. The blank folding mechanism is roughly classified into three types: a driving mechanism for the folding plate 68, a driving mechanism for the folding plate 70, and a driving mechanism for the pressing member 72. And
The folding plate 68 forms a required flap on the blank 26 and folds the blank itself, and further, the folding plate 70 folds the blank 26 into the folding folds 2.
0, the folds 20 are completely folded back so that the folds 20 are at the bottom, and the H-shaped member 12 finally formed from the blank 26 is pushed by the push-down member 72. The articles which are lowered and intermittently transferred on the bed 140 forming a part of the boxing machine arranged below and aligned in the standby position immediately below the folding mechanism (see, for example, FIGS. 5 and 6). It is forcibly supplied between a plurality of bottles 10) as shown. Therefore, each mechanism for performing these three basic operations will be described in order below.

First, the drive mechanism of the folding plate 68 will be described. The folding plate 68 is arranged as a pair of left and right members in opposition to each other in FIG. 4 (each mechanism for driving the pair of folding plates 68, 68 is described as follows). Since they have exactly the same structure, only the mechanism on the left side in FIG. 4 will be described for convenience). That is, the folding plate 68 is composed of a deformable member formed by processing a flat metal plate as shown in FIG. 5, FIG. 8 and FIG. 9 (1). Rectangular auxiliary member 7 extending to the
6 is fixed upright. As will be described later, the auxiliary member 76 functions to come into contact with the folding fold 20 of the blank 26 and forcibly fold the blank 26.

Further, both lower edge portions of the folding plate 68 are obliquely cut, and the cut edge portions are slightly parallel to each other in a direction opposite to the side on which the auxiliary member 76 is vertically arranged with a predetermined parallel width. It is bent at an angle so that the bent edge 78
Is formed. This bent edge 78 is the blank 2
It functions to bend the flaps 22 at the folds 18 for flap formation by contacting the respective flap formation scheduled portions 6 of FIG.
As shown in FIGS. 4 and 9, the folding plates 68 are vertically opposed to each other with a predetermined space therebetween, and are supported by the double-acting air cylinders 80 and 82, respectively, to have predetermined strokes. It is possible to move vertically up and down. For example, on the back surface of the folding plate 68, that is, on the flat surface on the side where the auxiliary member 76 is not disposed, a pair of protrusions 84, 84 are vertically arranged, and each protrusion 84 is connected to a vertical guide rail 86. It is fixed. The folding plate 68 is driven by an air cylinder 80 so that it can move up and down. That is, as shown in FIGS. 4 and 5, the carriages 92, 92 are movably arranged on a pair of rails 88, 88 horizontally arranged at a predetermined distance.
The carriage 92 is configured to sandwich each rail 88 by a pair of upper and lower guide rollers 90. A vertical support plate 94 is arranged between the carriages 92, 92 so as to bridge in the lateral direction. A horizontal support plate 96 is attached to the top of the vertical support plate 94, and the air cylinder 80 is attached to the horizontal support plate 96. Is fixed vertically upside down. A lower end portion of a piston rod 98 of the air cylinder 80 is fixed to an L-shaped bracket 100 attached to the guide rail 86, and the guide rails 86 are vertically and horizontally rotated on the vertical support plate 94 at predetermined intervals. Both sides thereof are slidably sandwiched by a plurality of guide roller groups 101 which are freely attached. Therefore, when the air cylinder 80 is biased by pressure, the piston rod 98 extends downward, whereby the guide rail 86 and the folding plate 68 attached thereto descend vertically by a predetermined stroke. As is clear from FIG. 4 and FIG. 9 (1), the pair of folding plates 68, 68 are arranged in such a positional relationship that the auxiliary members 76 fixed upright on the plate surfaces face each other. Moreover, the lower end edges of these auxiliary members 76 are always positioned above the blank folding back folds 20 of the blank 26 fed horizontally by the kicker 66.

Next, as shown in FIG. 7 and FIG. 9 (1), the drive mechanisms of the folding plates 68 are mounted on the carriages 92, 92, and the carriages 92, 92 move on the rails 88, 88. It is possible to approach and separate in synchronization with the horizontal. In this way, the structure in which the pair of folding plate drive mechanisms can be closely spaced from each other is to supply the blank 26 to be supplied.
This is because it is possible to correspond to the size of the item, which may differ depending on the form of the article to be packaged. It is preferable to use, for example, a pair of reverse screws 104 as a mechanism for performing this approaching / separating movement. That is, as shown in FIG. 7, two reverse screws 104, 1 arranged in parallel are provided.
Reference numeral 04 is threadedly inserted into each vertical support plate 94, and rotatably supports both ends of each reverse screw 104 by each bearing 106. As is clear from FIG. 4, the sprocket 108 is fixed near the right end of the reverse screw 104, and the sprocket 108, 1 provided on each of the adjacent reverse screws 104 is fixed.
A chain (not shown) is wound between 08. Therefore, if the reverse screw 104 is rotated by an appropriate handle, the pair of reverse screws 104, 104 respectively rotate in the same direction, and the spiral action of the pair of folding plate drive mechanisms causes the pair of reverse screw plates 104, 104 to rotate.
By moving the carriage on 88, they are brought closer to and farther from each other.

Next, the drive mechanism of the folding plate 70 will be described with reference to FIGS.
This will be described with reference to the drawings and FIG. 9 (1). Folding board 70
Is typically composed of a plate member having the shape shown in FIG. 9 (1) and FIGS. 5 and 6, and the folding plate 70 has a pair of rotating shafts 110, 110 arranged horizontally in parallel. A pair of folding plates 70 are fixed along the longitudinal direction at fixed intervals and fixed to each pair, and as shown in FIG. 5, FIG. 6 and FIG. The respective 70 have a predetermined width and are opposed to each other (thus, in this embodiment, there are a total of four folding plates 70). When the folding plates 70, 70 are observed from the axial direction of the rotating shaft 110 while waiting for the blank 26 to be folded, as shown in FIGS. 5 and 6, the individual folding plates 70 are It is slightly inclined inward, and the folding plates 70, 70 as a whole are approximately 150
It is held in an upwardly expanded posture at an angle of °. Then, by being biased by a drive mechanism which will be described later, the two folding plates 70, 70 move close to each other substantially vertically and take a palm-holding posture.

As the drive mechanism for the pair of folding plates 70, 70, for example, a double-acting air cylinder 112 shown in FIG. 4 is preferably used. That is, the air cylinder 112 is vertically fixed and supported vertically on the base frame, and the guide rail 114 is fixed and hangs down at the tip of the piston rod of the cylinder 112. As shown in FIG. 8, the guide rail 114 includes a horizontal plate 11 which is horizontally laid between vertical base frames.
A pair of guide rollers 118, 1 rotatably supported by 6
Both sides of which are slidably held by 18. As shown in FIG. 8, two link rods 120, 120 are symmetrically swingably supported on the upper portion of the guide rail 114, and the lower end portion of each link rod 120 has the rotating shaft 110. Link plate 122 connected and fixed to the tip of the
Are connected to each other via a pin 124. As shown in FIG. 8, the link mechanism constituted by the link rod 120 and the link plate 122 forming each pair, as shown in FIG.
0 and 70 are held at an angle of approximately 150 °. Then, by urging the air cylinder 112 with pressure, the piston rod thereof descends, and the guide rail 114 also descends vertically, so that the link rod 120 and the link plate 122.
Will drive the link mechanism constituted by. That is, as a result, the pair of folding plates 70, 70 are
As shown in (3) and FIG. 10 (3), the blanks 26 are brought into close contact with each other in the vertical direction, and the folded blank 26 is brought into close contact with the back 26 as described later. Fulfill

Next, the drive mechanism of the push-down member 72 will be described. This mechanism is driven by a double-acting air cylinder 126 for a predetermined stroke as shown in FIGS. 4, 6, and 9 (1) (from the standby position above the blank bending position to the folding plate). A plurality of articles 10 located below the blank 26 (which has already been molded as the intervening member 12) that has been vertically lowered and folded back to the operating position below the position where 70, 70 are disposed. Fulfill the function of forcibly supplying during. That is, this push-down member 7
As shown in FIG. 6 and FIG. 9 (1), 2 is composed of a channel member of a required length that expands downward in an eight shape, and is located at an intermediate position between the pair of folding plates 68, 68. , The longitudinal axis of the push-down member 72 is aligned with the straight line connecting the mutually facing auxiliary members 76, 76 of the folding plates 68 to maintain the horizontal posture. Depressing member 72
Is connected to the lower end of the piston rod 127 of the air cylinder 126 via a bracket 128 on its upper surface, and the bracket 128 is connected and fixed to a vertically arranged guide rail 130. Then, as can be seen from FIG. 7, a horizontal member 13 horizontally laid horizontally.
A vertical support plate 134 is fixed to the vertical support plate 13
The guide rails 130 are slidably supported from both sides by a guide roller group 136 provided in a pair of upper and lower sides and a pair of left and right sides. Further, another support plate 138 is horizontally fixed to the vertical support plate 134, and the air cylinder 126 is fixed upside down on the horizontal support plate 138. Since the push-down member 72 forcibly pushes down the blank 26 folded back to back to the article conveying position below as described later, the downward stroke of the air cylinder 126 is caused by the folding plate 68 by the folding plate 68. It is set to be larger than the lowering stroke of the two air cylinders 80 and 82 that perform the function of bending. The drive mechanism of the push-down member 72 is always standing by at the intermediate position above the folding fold 20 of the blank 26 which is horizontally supplied by the kicker 66 and placed at a fixed position. Therefore, even if the dimension of the blank 26 is changed, it is not necessary to move the blank plates 26 close to and away from each other as in the drive mechanism of the pair of folding plates 68, 68. There is something.

The operation sequence of a total of four double-acting air cylinders used in the blank folding mechanism shown on the left side of FIG. 4 is as follows. That is, the pair of air cylinders 80, 82 for lowering the folding plates 68, 68 are synchronously biased by pressure, and then the air cylinder 112 for driving the folding plates 70 (four in total) is biased by pressure. After that, a long air cylinder 126 for lowering the push-down member 72
Is in a pressure activated sequence.

In the figure, reference numeral 140 indicates a flat bed on which the article 10 is placed and supplied in a predetermined direction. A pair of left and right chains 142 circulates on the bed 140, and the pair of left and right chains is The article 10 is intermittently transported forward by a group of bars 144 which are laterally arranged at predetermined intervals. Further, reference numeral 146 indicates a guide plate which is provided so as to be adjustable depending on the distance between the articles 10 transferred on the bed 140.

Operation of the Embodiment Next, the operation of the molding and feeding device configured as described above will be described. Note that the operation sequence developed in each mechanism of the device shown in each drawing is described in the corresponding place each time, and thus the detailed description of each operation is omitted. In FIG. 4, a large number of blanks 26 stacked and stored in a hopper 28.
Are pulled down one by one from the blank 26 at the bottom under the suction action of a vacuum suction cup 34 that can be moved up and down, and on a pair of L-shaped rails 50, 50 arranged facing each other at a predetermined level. Placed horizontally. Then, the kicker 66 catches the rear end portion of the blank 26 and sends it to the blank bending position on the left side in the horizontal direction (in FIG. 4) to end the blank supply cycle.

The blank 26 thus transferred to the predetermined position of the blank folding mechanism waits for the folding operation at the fixed position. Further, in FIG. 4, a plurality of articles 10 (for example, bottles in this embodiment) are intermittently transferred on the bed 140 by a bar conveyor configured by the bar 144 and the chain 142, and the blank 26 stands by horizontally. The article group 10 arrives at the standby position immediately below the existing position in an aligned state and stops (see FIG. 10 (1)). Then, catching this timing, first, the pair of folding plate drive mechanisms operate. That is, the pair of air cylinders 80, 82 are synchronously biased by pressure, and the pair of facing folding plates 68, 68 vertically descend by a predetermined stroke. Therefore, Fig. 9
As shown in (2) and FIG. 10 (2), after the vertical auxiliary members 76 fixed upright to the folding plates 68 contact the folding folds 20 of the horizontally placed blank 26, respectively. Further down. For this reason, the blank 26 is pushed down at the folding fold portion 20 (specific end edges of the blank 26 are supported by the L-shaped rail 50) and folded back into a V shape. Become. Further, in the process of folding back the blank 26, each folding plate 68
The bent edge portion 78 formed in FIG.
As shown in FIG. 0 (2), the blank 26 is abutted against the flap-forming portions 22 and pressed against each other, and the flaps 2 are bent at a substantially right angle at the flap-forming folds 18.
Form 2.

The blank 26 is V-shaped by the pair of folding plates 68, 68.
Although it is bent by the mold, it does not yet come into close contact with each other back to back. Therefore, the blank 26 is folded for folding by actuating the group of folding plates 70 here. The eyes 20 are closely contacted back-to-back so that they are at the bottom. That is, when the air cylinder 112 is biased by pressure and its piston rod extends from the cylinder tube, each pair of link mechanisms constituted by the link rod 120 and the link plate 122 operates, and the respective rotary shafts 110, 110. Are each turned inward by a predetermined central angle. As a result, a pair of folding plates 70, 70 facing each other in FIGS.
Turn in the approaching direction by a predetermined center angle, respectively.
And, as shown in FIG. 10 (3), the palm stands in a substantially vertical upright position. Therefore, the blank 26 is forcibly sandwiched between the two folding plates 70, 70, and the blank 26 is folded back approximately 360 ° at the folding fold 20 and comes into close contact with each other back to back. As a result, the interposed member 12 shown in FIG. 1 is molded. At this time, the folding fold 2 of the member to be interposed 12
0 faces the group of articles 10 and 10 aligned above the group of articles stopped at the standby position of the bed 140 in the aligned state.

Next, a long air cylinder 1 that drives the push-down member 72.
26 is pressure biased, which causes the piston rod 127
Is extended and the push-down member 72 is vertically lowered by a predetermined stroke. At this time, as described above, since the push-down member 72 is positioned almost directly above the folding fold 20 of the blank 26 and aligned therewith, the press-down member 72 of the interposer 12 formed from the blank 26 is formed. The part on the opposite side (upper part) from the fold 20 is captured and this is pushed down all at once (9th
See Figure (4) and Figure 10 (4). Therefore, the H-shaped member 12 to be interposed is forcibly supplied to the adjacent gap between the plurality of articles 10, 10 stopped on the bed 140. In this case, since the folding fold 20 is located under the member to be interposed 12, the articles 10, 10
The member 12 to be interposed can be smoothly interposed.

According to the apparatus shown in this way, the blank 26 having the form shown in FIG. 3 is folded back to back at the folding fold 20 by the folding plate 68, and the flap is formed at the flap forming fold 18. The flap 22 is formed by bending the planned formation portion outward at a substantially right angle,
Finally, as shown in FIG. 1, it is possible to easily form the interposed member 12 having a special shape that exhibits an H shape in a plane.

After the blank 26 is formed as the H-shaped member to be interposed 12, the respective air cylinders are reversely biased and the folding plate 6 is pressed.
8, 68 and folding plates 70, 70 and pressing member 72
Is returned to the original position waiting for folding of the blank, thereby completing the interposed member forming and supplying step as one cycle. Further, the articles 10, 10 having the H-shaped members 12 to be interposed in the gaps adjacent to each other are intermittently transferred forward on the bed 140 again by the drive of the bar conveyor, and new articles 10 are again provided. , 10 subsequently arrive at the standby position of the blank supply mechanism and stop. Again hopper 28
Of the blank group placed on the, the blank 26 located at the lowermost part is again lowered to one sheet, horizontally moved to a fixed position in the middle of the blank folding mechanism, and waits again for the next blank folding operation. To reach.

In the embodiment using the blank forming and feeding device shown in the drawing, the blank 26 is bent into a V-shape at the folding fold 20 as shown in FIG. 3 and is folded outward to form the flap 22 at the fold 18. Although an example in which the bending operation is performed in a substantially synchronous manner has been described, as another procedure, as shown by a thick arrow in FIG.
May be bent at a right angle, and may be bent back to back in the next step. Further, first, the blanks are folded back until they are substantially back-to-back at the folds 20 for blank folding, and then, in the next step, at the folds 18 for flap formation, the folds 18 are folded outward at a substantially right angle. The step of bending may be taken.

EFFECTS OF THE INVENTION As described above, according to the apparatus for forming and supplying a member to be interposed in the boxing machine according to the present invention, the H-shaped member to be interposed is bent and formed from a flat plate-shaped blank, and The interposed member can be automatically supplied between a plurality of articles. Therefore, it is possible to integrally incorporate the bending forming process and the supplying process of the interposed member during the box making / boxing process in the boxing machine. Further, since the blank folded by the blank folding means has the folding fold on the lower side, it has an advantage that the member to be interposed can be easily interposed between a plurality of articles. Further, since the horizontally supplied blank is bent and formed above the plurality of aligned articles, it is possible to supply the blanks between the articles only by lowering the formed intervening member.
