Fig. 3 has represented some part of Fig. 2 with the decomposition view mode of amplifying, and it has illustrated first operation, and in order to see clearly Chu, has omitted other parts;
Fig. 4 has illustrated Fig. 3 part in another operation.
Represented to be packaged into the equipment of set product 19 with reference to accompanying drawing 1,1, it does as a whole, combines with the part of wrapping machine 100, and packing 3 along this part by predetermined feeding route 4 forward.Haul packing 3 by one group of pinch roll 5, and it is guided to first cutter sweep 6 forward with positive 3a and back side 3b.In institute's example, cutter sweep 6 has comprised the rotary cylinder 7 that blade 8 is housed, and it cooperatively interacts with another fixed blade 9 that provides at packing 3 back side 3b.Cutter sweep 6 cuts off packing 3 periodically and is divided into plate 2 along the line of cut of representing with T, and every plate produces relevant widthwise edge thus, considers and the relation of predetermined feeding route 4, identifies with base 2i and top margin 2s.
Measure between top margin 2s and base 2i along feeding route 4, monolithic plate 2 must have length L, like this, in the multiple package position that is connected on above-mentioned cutter sweep 6 back along feed direction, can make plate can intactly wrap in group products 19, for example in groups on the cigarette case.
Equipment 1 comprises a gluer 12, it surpasses cutter sweep 6 along feed direction, can be along predetermined direction P the travel forward F1 and the F2 that moves backward, direction P is vertical substantially with the feeding route 4 of packing 3, gluer 12 is along parallel with the line of cut T tree lace G that laterally is coated with, and 3 back side 3b are coated with last layer adhesive material 16 to packing.
Being connected on gluer 12 back along feed direction has two second cutter sweeps 10, and it periodically makes lateral incision 11 on the every plate 2 that order is sent here, and otch is from vertical side and parallel with line of cut T basically.Lateral incision 11 makes up in pairs, the transverse region 2 that formation is cut ', be tongue piece 13 to call it in the following text, it has connectionless three limits and amounts to the bonded assembly limit with one with 2 one-tenth of plates.In multiple package position 15, the first push rod 15a is along the predetermined feeding route by 15 ' expression, and advance forward from dead position by the direction that F3 represents, because the effect of push rod, the group products 19 that order is sent here advances forward, on relevant plate 2, whenever hit once successively, plate is wrapped on the product foldedly, and form " U " shape.In case push rod 15a is along forwards having finished a stroke to F3, and F4 gets back to its initial rest position in opposite direction, the top margin 2s and the base 2i of plate 2 just connect together, or rather, along being coated with the limit that tree lace G scribbles adhesive material 16 inside, contact with another limit is overlapping, form the packing box 23 of a tubulose thus, it have first 26, the second 27 with two relative sides 38; This moment two of packing box 23, vertically end 28 still was an opening, gave prominence to outside box 19 to be packaged in groups with given distance.In this example, carrying out the device that this packaging process adopted is conventional equipment, not expression in the drawings.
After above-mentioned packaging process, along predetermined feeding route 4 ', tubular wrapping box 23 is sent to forward, feeding route 4 ' parallel with the original feeding route 4 of packing 3, and along above-mentioned F3 direction to the reach distance, tubular wrapping box 23 is sent in the folding device 40, and folding device 40 surpasses at multiple package position 15 along feed direction, comes two open ends 28 of enclose box 23 by it.
Each open end 28 of packing box 23 forms a continuous U-shaped edgefold 39, and a tongue piece 13, and tongue piece 13 is separated with this edgefold 39 mutually by above-mentioned lateral incision 11, and is provided by zone 2 ' institute that cutter sweep 10 produces on plate 2.Edgefold 39 comprised from second 27 of tubular wrapping box 23 core 39 that extends ', and 38 two side direction parts 39 of extending from two sides respectively "; and tongue piece 13 extends from first 26 of packing box 23, and basically with this face in same plane.
As depicted in figs. 1 and 2, folding device 40 comprises a cylinder 20, it and relevant axle 29 usefulness keys connection, and several radial slots 21 are provided, and groove is separated from each other with same angular distance, and each groove proportionately holds a packing box 23.Axle 29 is designed to can be around the intermittent rotation of its axis 29 ' do, make cylinder 20 rotate (being anticlockwise shown in the figure) along the direction that F8 represents, thereby groove 21 orders are replaced on two positions: at first being the position of accepting packing box 23 from multiple package position 15, is that above-mentioned packing box 23 is delivered to the position of sending outside on the conveyer belt 35 then.
At Fig. 1, in 2 and 4 the example, cylinder 20 has comprised 90 ° four grooves 21 of being separated by separately, and the bottom surface of each groove forms an opening 37, and its size is less than the respective surfaces size of tubular wrapping box 23.
When groove 21 is in when accepting the position and accepting packing box 23, it along relevant feeding route 4 ', with perpendicular with a pair of first fixed fold devices of 30 expressions, the first fixed fold device is between multiple package position 15 and groove 21, and is and consistent with the relative vertically two ends 21a of groove.
From Fig. 1, can know in 2 and 4 and see, the position of each fixed fold device 30 makes with the open end 28 of corresponding packing box 23 and engages, this moment, packing box 23 was along feeding route 4 ' forward, and entering in the relevant groove 21, like this, when in the packing box 23 complete insertion grooves, the core 39 of above-mentioned each continuous edgefold 39 ' will be with direction bending shown in the F5 arrow among Fig. 1, and on the associated end face of group products 19, flatten, relevant tongue piece 13 is towards the vertical direction bending, and is basically perpendicular to first 26 of packing box 23, the inner face 22 of tongue piece is towards fixed fold device 30, and partly contacts with it.Particularly, since each fixed fold device 30 for the core 39 of associated end tabs 39 ' effect, two less side direction tabs have been produced, its profile is trapezoidal substantially, rotation direction F8 with respect to cylinder 20, identify them with back tabs 14 and preceding tabs 17, and the effect of fixed fold device 30 also make tongue piece 13 remain on first 26 of packing box 23 vertical substantially above-mentioned position on, at least when cylinder 20 time-outs be like this when accepting the position.
A pair of movable folder 31 also becomes the part of folding device 40, they are connected on the back of fixed fold device 30 along feed direction, separately alongside on two vertical end 21a that are in the groove 21 of accepting the position, when they suspended in cylinder 20 motions, the rear side of each packing box 23 that flattening is sent here in proper order was to tabs 14.Two movable folder 31 are from dead position, do to front travel along direction shown in the F6 earlier, engage to tabs 14 with each rear side this moment, and make it bend towards core 39 ' (core 39 ' flatten on the end face of group products 19 earlier) of edgefold 39, folder 31 is return stroke along direction shown in the F7 then, returns dead position.
From geometrical point, each fixedly spiral folder 24 can regard 1/4th of a tubular ring approx as, reverse 90 ° of shapes after the angle at the longitudinal axis along himself.
In fact, single folder 24 is made up of double- type screw element 24a and 24b, they are respectively external component and interior element, stretch in parallel to each other and combine a gap 24c is provided, when equipment 1 work, or say so more accurately when cylinder 20 rotates, gap 24c can hold the part of packing box, make that the tongue piece 13 of respective end tabs of each packing box 23 slides along gap 24c this moment, its inner face 22 faces toward inside spin element 24b.From Fig. 2, can see clearly, each spiral folder 24 combines with cylinder 20, one of its extreme end limit 24 ' close, and another extreme end limit 24 with corresponding vertical end 21a at first groove 21 of accepting to stop on the position " close with corresponding vertical end 21a of second groove 21 that on delivery position, stops; Limit 24 ' the position be radially basically along cylinder 20, so can correctly introduce gap 24c to tongue piece 13, and the other end 24 " the position be arranged essentially parallel to the pivot center 29 of cylinder 20 '.
As utilizing Fig. 3 illustrated, the width h1 of external spiral element 24a makes tongue piece 13 in a single day be positioned among the 24c of gap greater than the width h2 of parallel interior element 24b, will give prominence to outside interior element 24b, exposes the part of its inner face 22.
At last, folding device 40 comprises a pair of the 3rd fixed fold device 32, and their position is along the direction of sending conveyer belt 35 outside, and is consistent with the end face of cylinder 20 basically, and tongue piece 13 is flattened on side direction tabs 14 and 17.
Or rather, as shown in Figure 2, on packing box 23 delivery positions, tongue piece 13 along direction bending shown in the arrow F9, flattening is on side direction tabs 14 and 17, and at this moment, second push rod 36 of a routine is pushed ahead by the opening 37 of groove 21 on the cylinder 20, packing box 23 is released certain distance from groove, make it along belt conveyor 35 forward by direction shown in the F10.
So far two end faces 25 are closed fully, can be sent to the packing box that present usefulness 34 is represented in this example in unaccounted other fexible unit, and be received by them.
Equipment 1 is the part of wrapping machine 100, wrapping machine is as the packing of product of cigarette case and so in groups 19, when equipment 1 work, the continuous band of packing 3 advances along predetermined feeding route 4, and adopt first cutter sweep 6, transversely line of cut T is divided into monolithic plate 2 periodically to band, and every plate has base 2i and top margin 2s.
Along basic parallel with the line of cut T tree lace G that is coated with, and close 2i place, plate 2 base, on the 3b of the back side of packing 3, be coated with last layer adhesive material 16 with movable gluer 12.
To pack the packing box of 19 products in groups in order to prepare that plate 2 is formed one, surpassing on plate 2 vertical limits of gluer 12 positions, make lateral incision 11 with second cutter sweep 10, and plate 2 and the product on multiple package position are aligned, this moment push rod 15a along relevant feeding route 15 ', begin to promote product by direction shown in the F3, and shift onto above the plate 2, therefore make plate 2 be folded into the U-shaped shape around group products 19; Then the top margin 2s of plate and base 2i are stacked, base 2i on top margin 2s, thereby form a tubular wrapping box 23 with two open ends 28.
After having finished these initial process, the shape that tubular wrapping box 23 presents has first and second 26 and 27 as shown in Figure 1, and two sides 38.Two vertical end 28 openings still, each opening has a continuous U-shaped edgefold 39 and a tongue piece 13 that is surrounded by lateral incision 11.And continuously edgefold 39 comprised a core 39 ' and two side direction parts 39 ".
At this moment, tubular wrapping box 23 and is forced into etc. in the groove 21 of the cylinder 20 of accepting the position along predetermined feeding route 4 ' (the skew certain distance from original feeding route 4 along the F3 direction) forward.
As shown in Figure 1 and Figure 4, when packing box 23 enters relevant groove 21, the core 39 of edgefold 39 ' tackled by the first fixed fold device 30,23 bendings along direction shown in the F9 towards packing box, and contact with the end face of group products 19, in this process, side direction tabs 14 and 17 before and after producing.In same motion, tongue piece 13 also is blocked, and be bent to first 26 of packing box 23 vertical substantially position on.
When packing box 23 is contained within the relevant groove 21, and tongue piece 13 flattens back transverse flap 14 with movable folder 31, as shown in Figure 2 when remaining on perpendicular to first 26 position by folder 30.
Then, cylinder 20 beginnings are rotated along direction shown in the arrow F8, have changed a step-length that is equivalent to angular distance between two grooves 21, force thus among the gap 24c of each tongue piece 13 between spiral folder element 24a and 24b.
From Fig. 1, can know in 2 and 3 and see, because cylinder 20 is around the rotation of self axis 29, make tongue piece 13 slide along relevant gap 24c, thus packing box 23 is taken to delivery position, and another dead slot 21 (not shown)s have occupied and accepted the position, prepared to accept next packing box 23.When cylinder 20 rotated, two tongue pieces 13 were flattened gradually, from vertical substantially position move on to roughly with 23 first 26 identical faces of packing box on, at this moment packing box 23 has arrived delivery position.Simultaneously, each tongue piece 13 will cross relevant fixedly gluer 18, thus one deck adhesive material will be coated on the inner face 22 of tongue piece 13, and roughly curved gum spot point forms ring-type.
When cylinder 20 rotates about 90 ° around himself axis 29, when group products 19 and relevant packing box 23 thereof are taken to delivery position, the front side to tabs 17 by second fixedly tabs 33 interceptions and the flattening; At last, packing box 23 is released outside the groove 21 by push rod 36 (Fig. 2), be sent to therefrom on the belt conveyor 35, and through between the 3rd fixed fold device 32, two tongue pieces 13 engage with the 3rd fixed fold device 32, along the direction bending shown in the F9, thereby be driven plain in side direction tabs 14 and 17, and the core 39 of respective end tabs 39 ' on.
Importantly should be understood that and adopt the fixedly gluer 18 of position near cylinder 20 end faces, big along the space that the feeding route 4 required spaces of packing 3 can't be more required than prior art approach, in the prior art, finished before packing box 23 folding process along vertical limit coating process of feeding route.
In addition, coating process of the present invention only just carries out when tongue piece 13 folds, so just in case the cycle of operations of packing interrupts, if also there is not gluing on tongue piece 13, can not cause the dry problem of adhesive material.
