Carrying function can be realized in plane station after Handling device catches product array.
When using bracing frame shaping assembling device to operate bracing frame, needing that lower support is set along product throughput direction and putting up shape assembling device, Handling device, upper support frame shaping assembling device.Lower support is put up shape assembling device and is positioned on product travel line, and Handling device is across on product travel line and packing box transmission line, and upper support frame shaping assembling device is positioned on packing box transmission line.Product on product travel line is in Packet State, forms product array thus, and this product array is vertically and horizontally arranged state.
Product array is transported to lower support and puts up shape assembling device position.The minimum size of the cross-sectional plane of bending mold 22 is a bit larger tham the size of location division 9 outer ledge, and namely the width of the minimum cross-section of bending mold 22 is a bit larger tham W4, the length of minimum cross-section of bending mold 22 is a bit larger tham L2.During use, product array is positioned at lower support and puts up immediately below shape assembling device, the gradual change type simultaneously lower support frame 8 being placed in bending mold 22 guides the opening part of die cavity, lower support frame 8 only have support portion contact with bending mold 22, as shown in the step1 part of Figure 19.Under initial condition, first order lifting assembly, second stage lifting assembly all shrink, and separate between pushing tow mould 23 with bending mold 22 with ultimate range.Then, first order lifting assembly stretches out, and shaping assembling mould is dropped to product array place height, until lower support frame 8 and product array contact position, as shown in the step2 part of Figure 19, now product array is positioned at gradual change type guiding die cavity.As shown in the step3 part of Figure 19, second stage lifting assembly stretches out, and the downward bracing frame 8 of pushing tow mould 23 is moved, and moves in gradual change type guiding die cavity.Guide after in die cavity at gradual change type when pushing tow mould 23 stretches into, as shown in the step4 part of Figure 19, the bending action contrary with the sense of motion of pushing tow mould 23 is done in parcel, relative positioning portion, support portion.
The size of rectangular shape formed due to the bump array of pushing tow mould 23 and the outer ledge of location division 9 measure-alike, causes pushing tow mould 23 to be partial to the outside of location division 9 with the contact position of location division 9.Force the bending deformation extent of support portion 11 obviously obvious than the bending deformation extent of parcel 10 like this.This bending deformation extent conference causes the structural damage of lower support frame body at crease line place, and then can not return to original form.Amount of recovery after the bending distortion journey of support portion 11 forces it to be bent to form in this embodiment is less, namely still can keep larger bending amount; And parcel 10 has very strong elasticity after bending.
As shown in the step5 part of Figure 20, pushing tow mould 23 continues to stretch into gradual change type and guides die cavity, and support portion, parcel bend further.As shown in the step6 part of Figure 20, when support portion, parcel guide after die cavity through gradual change type completely, support portion, parcel are bent to form the state vertical with location division; Parcel is owing to having elasticity, and it has the trend of folder to product array.Lower support frame 8 has been arranged on the medium position of product array.
Be subject to the reasons in structure that the bearing of trend of the groove of the waveform core paper interlayer of the long edge position of location division 9 is vertical with the bearing of trend on long limit, cause bending to want large far away in the external force of the support portion 11 at the outer force rate bending broadside place of the support portion 11 of long edge position.Reach desirable to make the support portion 11 at this place and be bent into shape state, as shown in figure 21, be positioned at the support portion 11 of the long edge position of location division 9, the guiding setting effect in setting portion 25 is also subject in bending deformation process, the bending molding time of the support portion 11 at this place is made to compare the bending molding time of remaining support portion 11 long, therefore bending degree is kept, the support portion 11 at this place has and desirable is bent into shape state.As shown in the step7 part of Figure 20, after lower support frame 8 bends and is shaped, first order lifting assembly, second stage lifting assembly return to initial condition.
Through above-mentioned shaping assembly manipulation, take advantage of a situation at crease line 12 place of lower support frame and bend.The crease line 12 of lower support frame is all on the surface of the same side, and therefore, when bending, the overbending direction of four parcels, 10, four support portions 11 is identical.In lower support frame bending process, parcel 10 and support portion 11 bend in the same way, forming the spatial structure of ring-type, as shown in Figure 7, forming the through hole for holding product array between parcel 10.In bending process, be subject to the effect of linear pattern otch 13 between adjacent parcel 10, can not interfere with each other between adjacent parcel 10; Again because linear pattern otch 13 stretches in location division 9, when therefore fully can ensure that adjacent parcel 10 bends, location division 9 can not be torn.
Lower support frame 8 is arranged on the medium position of product array, and under these circumstances, lower support frame all has constraint effect to whole product array, and product array is firmly fixed togather.The product array being provided with lower support frame is transported to Handling device position after disengaging lower support puts up shape assembling device.
In an initial condition, handgrip is positioned at the top of product travel line to Handling device all the time, and the distance between the clamping plate 36 on handgrip is greater than the width of product matrix, and the volume of the grasping part between clamping plate is in maximum state.The product array being provided with lower support frame is positioned at after immediately below handgrip, and translation lifting mechanism drives handgrip to decline, until product array is positioned at grasping part handgrip stop descending motion.Spacing between baffle plate 40 is identical with the length of product array, therefore product array is between two clamping plate 36 under the restriction of baffle plate 40.Screw rod 8 rotates, and impels clamping plate move toward one another, and then two clamping plate 36 clamp product array.Product array is caught by handgrip, after the drive of translation lifting mechanism, do upward movement.After product array departs from product travel line, translation lifting mechanism moves horizontally, and makes product array move to the top of packing box transmission line.Then, translation lifting mechanism does descending motion, and product array declines to packing chest position.Packing box transmission line places packing chest, and screw rod enters packing chest at product array and places counter motion steadily, and handgrip unclamps product array, and the product array being provided with lower support frame thus enters in packing chest.
Die 27 is positioned at punch 30 and is realized on the reciprocating track of horizontal linear by translation lifting mechanism.As shown in Figure 12,13,14,15, during use, product array and die lay respectively at the two ends of slide rail.The product array place station being positioned at packing chest is forming station, and die place station is pre-forming station.Die is placed the upper support frame 1 being in plate-like structure.
As shown in figure 12, the support portion at upper support frame 1 edge is subject to the supporting role of die 27 edge, and the parcel of the centre of upper support frame is subject to the supporting role of the rectangle terrace with edge of the projection in the middle of die 27, now, the position point of upper support frame is directly over groove 28.Translation lifting mechanism drives punch 30, and be placed in by punch 30 in the pros of die 27, then translation lifting mechanism does descending motion, drives punch 30 to move to die 27 position.After punch 30 contacts with upper support frame, its annular protrusion just contacts with location division.Punch 30 continues to the motion of die 27 position, and now groove 28 place of upper support frame 1 to die 27 heads into by punch 30, upper support frame is taken advantage of a situation distortion, as shown in figure 12.The opening part of groove 28 is covered by upper support frame, therefore between upper support frame and die 27, forms semi-enclosed region.During upper support frame distortion, groove 28 is reduced gradually by the region that upper support frame is separated, and air is discharged from the gap between upper support frame and die 27.Support portion, parcel all bend along crease line under the mutual extruding of punch 30, die 27.When bending, the overbending direction of parcel 3, support portion 4 is identical, and each parcel 3 bends along the crease line of self in the direction contrary with aforementioned overbending direction.In upper support frame 1 bending process, parcel 3, relative positioning portion, support portion 42 bend in the same way, the relatively horizontal parcel bending of longitudinal parcel, horizontal parcel is covered in the side of the rectangle terrace with edge of die 27 intermediate projections, longitudinal parcel is covered in the end face of the rectangle terrace with edge of die 27 intermediate projections, form the spatial structure of ring-type, between parcel 3, form through hole, the upper support frame after shaping as shown in Figure 5.In bending process, be subject to the effect of linear pattern otch 6 between adjacent parcel 3, can not interfere with each other between adjacent parcel 3; Again because linear pattern otch 6 stretches in location division 2, when therefore fully can ensure that adjacent parcel 3 bends, location division 2 can not be torn.
The effect of die 27 is profiles of analog equipment array, makes upper support frame complete shaping before formal use.The forming process of upper support frame relies on the mutual squeezing action of external object, if directly complete shaping operation on product array, not only bend shaping poor effect, this is because the size of not every product array is all consistent, so bending part can deviate from crease line, also can extruded product, make product appearance impaired.So, the preform effect that preform assembly plays, significant with the assembling effect of realizing ideal for precision bending bracing frame.
As shown in Figure 13,14, the upper support frame after bending is shaped is held by the sucker 32 on punch 30, and translation lifting mechanism does upward movement, and drive the punch 30 being adsorbed with the upper support frame of shaping to leave die 27, then translation lifting mechanism does horizontal rectilinear motion.Upper support frame by bottom punch 30 pushing tow to groove 28 time demolded parts 29 on push rod be pushed, make spring-compressed, thus when upper support frame does upward movement with punch 30 extend action of push rod can help upper support frame depart from die 27.Punch 30 moves to forming station from pre-forming station under the drive of translation lifting mechanism, and upper support frame is positioned at the top of product array.Then, translation lifting mechanism does descending motion, makes the punch 30 being adsorbed with upper support frame 1 move closer to product array, until upper support frame is mounted on the surrounding of product array.
The consistent size of the through hole formed after the Outside Dimensions of product array and upper support frame bend.Be close on product array under the elastic reaction that parcel 3 has at material own, make four periderm upper support frames of product array tightly fixing.Just in time be positioned at packing chest time upper support frame contacts with product array, support portion 4 is pressed on packing chest inside under natural resiliency effect.Parcel 3 place of upper support frame only has horizontal parcel to contact with product array, and longitudinal parcel covers the top of product array, and after packing chest encapsulation, longitudinal parcel is pressed to product array by case lid.The trend that parcel is inwardly launched impels parcel to be clamped on product array; Be subject to the impact of the flared movement tendency in support portion, upper support frame struts in packing chest simultaneously, therefore upper support frame can maintain static after being arranged on product array top, plays the effect of fixed product array and positioning product array.After upper support frame is in place, the cylinder 31 in projection stretches out, piston rod from the through hole the location division of upper support frame through stretching to the lower support frame being arranged on product array medium position.Piston rod promotes lower support frame and moves bottom product array, until lower support frame moves to the bottom of product array.After this, cylinder 31 shrinks, and returns to initial condition; Sucker 32 discharges upper support frame; Punch 30 does upward movement with translation lifting mechanism, repeats said process when next product array arrives.
After upper support frame and lower support frame are arranged on product array outside, it immobilizes relative to the position of product array, and top, each support portion, to packing chest inwall, makes to keep spacing between product array and packing chest.Bracing frame of the present invention achieves the effect of registration device in prior art thus, also avoids using interlayer.Because upper support frame, lower support frame are all plate-like structure, occupy little space after ranked and stacked pile, space availability ratio is higher, stacked bracing frame entirety comparatively consolidation, has very strong resistance to compression, shock-resistance features, makes bracing frame storing moving convenient.
Bracing frame is firm in structure under stereoscopic-state, and when major cause is stereoscopic-state, the force structure of bracing frame changes, and the stability of force structure improves.Simultaneously, the long limit of bracing frame is arranged also can optimize force structure, the parcel of bracing frame is after bending, the parcel of location division surface stress-bearing capability owing to being bent, the support of support portion and improving, this is because the bearing of trend of the groove of the waveform core paper interlayer of long edge position is vertical with the bearing of trend on long limit, larger external force can be born from direction in parallel in location division, parcel, support portion bends, make parcel, support portion with nonparallel direction, location division on can bear larger external force, and then impel location division on direction nonparallel with it, namely favour location division or larger external force can be born perpendicular on the direction of location division, parcel, support portion are subject to the effect of location division, larger external force can be born in direction that is vertical or that favour its surface, between parcel like this and location division and the interphase interaction of support portion and location division, complement one another, finally make whole bracing frame sound construction under stereoscopic-state.
After vanning, product carries out joint sealing.In the present embodiment, upper support frame is positioned at the support portion of the long edge position of location division is two sectional type structure, and namely bracing frame is provided with at this support portion place the opening extending to location division.The upper support frame of this structure is applicable in the packing chest of eye-splice-type encapsulating structure, because the outside of the deck portion of this type of packing chest is provided with eye-splice, eye-splice is finally inserted in lower box.
