Abstract
To prevent the generation of a bridge and to quicken and facilitate the flap folding process, by folding the upper flap for the No. 1 flaps which are separated up and down while lifting a corrugated fiberboard from the stock stage by a suction pad, to open the corrugated fiberboard box. A multiple number of corrugated fiberboards 12 are loaded on a stocker 14 under a state where the corrugated fiberboards contact positioning devices 16, 18. A rotary arm 22 is made to descend; at a sensor Xc, a suction pad 20 draws up the corrugated fiberboard 12 on the top. While the corrugated fiberboard 12 is lifted by making the rotary arm 22 ascend, the corrugated fiberboard 12 is gradually and naturally opened by its own weight. Linked with the ascending of the rotary aim 22, a folding claw 30 is made to turn downward and folds an upper flap FIu; by this motion, the corrugated fiberboard 12 is forced to open. The rotary arm 22 then carries the corrugated fiberboard 12 to a flap folding stage. For the carried corrugated fiberboard 12, a remaining flap folding process is performed.
Description
The present invention is a method of making chest with carton blank, and this method is that lamellar carton blank is opened, and baffle plate is folded into then sealed.
As everyone knows, carton blank is upper and lower two pairs of baffle plates to be arranged respectively, be folded into laminally, thereby must make chest to laminal carton blank before using.
Usually, making chest with carton blank is following carrying out.
(1) at first, shown in the 10th figure (a), from the side pressure is added on the laminal carton blank 112, it is opened become cuboid (with reference to the 10th figure (b))
(2) shown in the 10th figure (c), fold into a pair of upper and lower baffle plate F that separates in two pairs of baffle plates that constitute the chest bottom on the carton blank
1The overhead gage F of (being called Internal baffle)
1U, lower baffle plate F
1L.Shown in the 10th figure (d), fold into a pair of baffle plate F that divides right and left then
2The right baffle-plate F of (being called outer baffle)
2L, right baffle plate F
2R makes it become the shape shown in the 10th figure (e).
(3) with the seam of the outer baffle that folds into as the center, carton bottom is sealed (with reference to the 10th figure (f).Sealing can utilize splicing tape, rubber strip, U-shaped bail, heat to fuse etc.
Like this, laminal carton blank through opening, fold into baffle plate, the sealing three process is made into chest.But, when in a single day baffle plate folds into, just produce recuperability, reverted back to the appearance of opening again by the baffle plate that folded into, therefore sealing need be carried out outer baffle being pressed in fold on the position.In addition, when the abutment joint of outer baffle not being sealed as the center, outward appearance is just bad, simultaneously can not guarantee full intensity, therefore, should prevent that shape from collapsing, making under the situation of left baffle keeping parallelism, seal as the center with the abutment joint of outer baffle.
Because the size of carton blank is fixing, sell the carton blank that various sizes are arranged on the market, therefore the machine with carton blank manufacturing chest must be able to utilize the carton blank of various sizes to make chest, requires machine to have versatility.And opening carton blank, fold into baffle plate, sealing in each operation, add the size difference of carton blank, all must have and will adjust mechanism that opens blank etc., known method with carton blank manufacturing chest can not promptly adapt to the variation of size, thereby makes the sort of machine with carton blank manufacturing chest complicated, and machine also is difficult to realize miniaturization and.
Adopt the method for known manufacturing chest, folding at baffle plate has the trend that often breaks down in the operation.This can know in the 10th figure (c) and see, as long as outer baffle F
2Shut a little, Internal baffle F
1Will be subjected to the obstruction of outer baffle and can not fold into.At outer baffle F
2Be under the closing state, will collide with outer baffle and form the bridge shape in case Internal baffle folded into, thus, because outer baffle F
2The fault of closing and causing is called bridge formation.And when taking place to build bridge, Internal baffle F
1Fold into by force, then inside and outside baffle plate produces distortion, damages, and carton blank also just becomes bad goods.Therefore, make the method for chest by carton blank with known, when owing to take place to build bridge at Internal baffle F
1On when producing to a certain degree resistance, baffle plate folds into operation and will interrupt at once.And the operating efficiency that the interruption of this operation can make baffle plate fold into operation significantly reduces.In addition, also provide a kind of limit by affirmation outer baffle F such as sensors
2Be not in and harm the position, open outer baffle forcibly on the limit, folds into Internal baffle F then
1Method.But baffle plate folds into operation can not carry out rapidly, also makes with the machine construction of carton blank manufacturing chest complicated simultaneously.
The purpose of this invention is to provide and a kind ofly can prevent bridge formation reliably, that can carry out quickly and easily that baffle plate folds into operation makes the method for chest with carton blank.
In order to reach this purpose, the present invention is adsorbed carton blank with sucker, is lifting the process from the location of getting the raw materials ready, and the overhead gage of upper and lower the 1st pair of baffle plate that separates is folded into, and carton blank is aloft opened.
In addition, preferably along with the horizontal parallel datum line of carton blank, carton blank centering reserve stockpile is put, for example the edge alignment fiducials line below the carton blank is carried out centering, sucker is adsorbing this blank on the transverse center of carton blank, be preferably in to aim at the said reference line and carry out centering, simultaneously at carton blank transversely also under the state of centering, fold into remaining baffle plate, seal.Like this, can be under the dimension modifying situation of carton blank, when baffle plate folds into, when sealing, do not need to align the variation that just can adapt to size at an easy rate.

Seeing figures.1.and.2 illustrates the method for the present invention with carton blank manufacturing chest, and it is to be undertaken by the machine 10 of making chest with carton blank.Carton blank 12 is folded into lamellar being deposited on the stacking device 14, carton blank 12 is carried out the centering (i.e. location) of X-direction (laterally) and Y direction (vertical or short transverse) on the stacking device objective table.That is to say, the machine 10 of making chest with carton blank has can be at the align member 16 of X-direction activity and the align member 18 that can slide in Y direction, align these and locate the centering that parts 16,18 just can carry out X-axis and Y direction, above stacking device 14, the vacuum cup 20 of making the machine 10 of chest with carton blank is in holding state, levelling carton blank 12 makes this sucker be positioned at carton blank 12 at the center of X-direction X in the position of X-direction
COn.That is to say, make W, then will align align member 16 slidably at center X if the amplitude of carton blank is got
CW/2 place, the left side.In addition, pre-determined the datum line Y that is parallel to X-axis
O, make bottom margin (following edge) the 12a alignment fiducials line Y of carton blank
OCarry out the centering of Y direction,, need only align member 18 for this reason from datum line Y
OThe distance of removing the baffle length that is equivalent to carton blank 12 forward gets final product.
As mentioned above, for matching, slide into decentre X to align member 16 respectively with size as the carton blank 12 of object
CThe position of left side W/2, align member 18 from datum line Y
OThe length that is equivalent to baffle plate towards front slide.The present invention makes the method for chest, and as described below, align member 16,18 does not just need to remake and aligned except doing above-mentioned levelling, therefore adapts to the change in size of carton blank 12 easily.And most carton blanks 12 is all to be deposited on the stacking device 14 with align member 16,18 contacted states.
The surface of sucker 20 is towards the below and be installed in the front end of revoliving arm 22, and the revoliving arm lifting freely is contained on the pillar 24.In addition, be used for a pair of baffle plate (Internal baffle) F of upper and lower separation
1In overhead gage F
1U folds into folds into the front end that claw 30 is assembled in revoliving arm 22.
Shown in (A) among Fig. 1, in said structure, make revoliving arm 22 declines and be in center X
COn the position, the uppermost carton blank 12 of sucker 20 absorption, revoliving arm 22 rises shown in figure (B) then, and for example from the top, revolution is transported to next process to carton blank 12 in a clockwise direction.
A principal character of the present invention is to make revoliving arm 22 to rise, and when lifting carton blank 12, carton blank is opened.That is to say that in lifting process, carton blank 12 relies on deadweight to open naturally gradually.And the action that folds into claw 30 is that rising with revoliving arm 22 links, and relies on deadweight and when opening automatically, folds into claw 30 to rotate downwards, overhead gage F
1U folds into, shown in figure (B), because this overhead gage F
1U folds into, and carton blank 12 is opened forcibly.
Revoliving arm 22 turns to sucker 20 always and is in baffle plate and folds into center F
C, descend then, carton blank 12 is transported to baffle plate folds into the location (referring to (c), (D) among Fig. 1; (D), (D ') among Fig. 2, Fig. 3).
Be centering to baffle plate and fold into center F
CAfter going up, be transported to baffle plate fold into the location the surplus baffle plate in carton blank 12 enterprising Xingqi fold into operation.That is: at first be to be hidden in the following claw 32 of folding into to rise ground the lower baffle plate F in the Internal baffle on while rotating
1L folds into (referring to the 3rd figure (D ')), and tuck-in panel 34,36 is rotated then, left and right the 2nd couple of baffle plate F that separates
2In about two baffle plate F
2R, F
2L folds into (referring to Fig. 4, Fig. 2 (D ")).Certainly, when rotating, make to fold into claw 30 risings, make to fold into claw 32 declines with tuck-in panel 34,36.
As mentioned above, lift in the process, because overhead gage F at carton blank
1U folds into, and carton blank 12 is opened, this moment shown in the 3rd figure (D '), about baffle plate F
2R, F
2L is backed down, and is not in overslaugh lower baffle plate F
1On the closed position that L folds into, so lower baffle plate F
1Folding into of L just is not subjected to left and right baffle plate F
2R, F
2The overslaugh of L, and can fold into quickly and easily.
That is to say, in the process that carton blank 12 lifts, along with overhead gage F
1U folds into, the present invention that blank is aloft just opened, and so the leeway that bridge formation takes place is Internal baffle F
1Fold into can be rapidly, carry out accurately and reliably, and owing to can prevent the generation of building bridge really, therefore inside and outside baffle plate F
1F
2Distortion, damage and can not produce; In addition, do not have to cause baffle plate to fold into the phenomenon of process interruption owing to building bridge yet.
Also need not utilize sensor etc. forcibly outer baffle F
2Fold into Internal baffle F after pressing off
1, therefore, can simplify the machine 10 of making chest with carton blank, make its small-sized, lightweight.
Left baffle F
2R, F
2The formation of the tuck-in panel 34,36 that L uses, make it can and X, 16 interlocks of axial align member are toward or away from baffle plate center F
C, therefore, in case according to the size of carton blank 12 align member 16 has been done levelling, then tuck-in panel 34,36 just can automatically move to given position, does not need the size levelling tuck-in panel 34,36 according to carton blank 12.That is to say,, do not need that baffle plate is folded into the location and align, therefore just can not adapt to the change of size as any levelling along with the variation of carton blank size.
As can be seen from Figure 2, center seal S
CBe located on the X-direction and fold into center F from baffle plate
CGiven distance L place.Distance L should be chosen to equate or longer suitable distance with the width of carton blank.Therefore, as long as carton blank 12 is transported to given distance L, carton blank just is centered in center seal S on X-direction
COn, so blank moves to the sealing location.
As shown in Figure 5, to center seal S
CTherefore in the course of conveying, tuck-in panel 34,36 remains on and folds into the position, plays guide function, can prevent that the shape of carton blank 12 in course of conveying from collapsing.At the latter half of carrying, tuck-in panel 34,36 is left carton blank 12, for this reason, along carrying path guide member 38 is set suitably, takes over guiding by guide member 38 in succession after tuck-in panel 34,36, can continue to prevent that carton blank 12 shapes from collapsing.
Thereby as long as carton blank 12 has been carried given distance, sealing mechanism is just sealed up carton blank 12.Sealing mechanism has the spool 40 that splicing tape 39 packages are got up as shown in Figure 7 during for example it constitutes.Limit revolution splicing tape spool 40 limits are risen its, the abutment joint 42 of the 2nd pair of baffle plate as the center, with splicing tape 39 stick on carton blank 12 below, thus carton blank 12 is sealed.Be illustrated on Fig. 8 through the chest 12 that the blank case is opened, each operations such as baffle plate folds into, sealing are made.
Like this, making in the machine 10 of chest center seal S with carton blank
CBe positioned at and leave baffle plate and fold into center F
CGiven distance L place.Therefore, as long as folding into the location from baffle plate moves given distance L, carton blank 12 just can frequent centering center seal S
C, carton blank 12 is packed under the centering state.Adopt this structure,, also do not need sealing mechanism is aligned even the size of carton blank 12 has change.Promptly no matter to the carton blank 12 of what size, the levelling that needn't carry out sealing mechanism just can easily adapt to the change of size.
As mentioned above, the present invention makes the method for chest, as long as align detent mechanism 16,18, just passable according to the size of carton blank 12, folding into the location at baffle plate does not need levelling with the sealing location.The dimension modifying that therefore, can easily adapt to carton blank 12.
In addition, as shown in the figure, fold into the location from baffle plate, as long as the parallel mobile given distance L of carton blank, just can reach the sealing location, given distance L has considered that the amplitude W of carton blank 12 sets minimum of a value afterwards for, therefore the fed distance of carton blank 12 is very little just enough, making the machine of chest can make very for a short time with carton blank in the length of X-direction, make this machine Miniaturizable, and till folding into the location from the location of getting the raw materials ready to baffle plate, rotate and carton blank is carried by sucker 20, this structure uses carton blank to make machine 10 miniaturization more of chest, makes the erection space of this system punch-out equipment also littler simultaneously.
As Fig. 6, shown in Figure 9, when being preferably in sealing guide member 44 is contacted with carton blank upper surface 12U face, other guide member 46 is sealed all sidedly with under the contacted state of front end of the 2nd pair of baffle plate at the carton blank back side, can prevent fully that under this state the shape of carton blank R from collapsing, two baffle plates are parallel about keeping, and the abutment joint 42 that can easily carry out with outer baffle is the sealing at center.Certainly, the structure of these guide members 44,46 does not need to align the change that just can adapt to the size of carton blank 12.
As mentioned above, carton blank is at datum line Y
OOn carry out centering and get the raw materials ready, sucker 20 is in the transverse center X of carton blank
COn adsorbing carton blank and carrying.In addition, at said reference line Y
OOn when carrying out centering, also carry out under the state of centering remaining baffle plate being folded into and sealing in the transverse center of carton blank.The method of this manufacturing chest can adapt to the change in size of carton blank, does not need levelling when baffle plate folds into and seal, and can easily adapt to the change of carton blank size.
The above embodiments are to explanation of the present invention, are not to any qualification of the present invention, and that has done in technical scope of the present invention changes shape, improvement etc., is to comprise in the present invention certainly all.For example in embodiment, used a sucker 20, yet also can install a plurality of suckers, can prevent reliably like this when revoliving arm 22 rotates, owing to rotary inertia causes departing from of carton blank position.
In addition, also can be as folding into claw that it is more specific folding into baffle plate, also can be used as tuck-in panel and it is more specific.
As mentioned above, the present invention is adsorbed carton blank with sucker, lifts the process from the location of getting the raw materials ready, and the overhead gage of Internal baffle is folded into, and carton blank is just aloft opened.
In this method, the left baffle of outer baffle all is subjected to pushing of Internal baffle overhead gage and opens, and is not in the closed position that the lower baffle plate that hinders Internal baffle folds into.Therefore lower baffle plate fold into the obstruction that is not subjected to left baffle, and can carry out quickly and easily.
That is to say, method of the present invention, the leeway that bridge formation takes place, inside and outside baffle plate can not produce distortion yet, damage.
In addition, can not produce interruption owing to bridge formation makes baffle plate fold into operation yet.
In addition, the machine with carton blank manufacturing chest of implementing manufacture method of the present invention constitutes and can oversimplify, can also small-sized, lightweight.
