Description
Technical field
The present invention relates to by along the track (for example circle, straight line, racing track etc.) of regulation in horizontal surface intermittently mobile possess the both side edges portion of the pair of right and left clip clamping bag of holding part freely that opens and closes respectively; Keep this bag to hang state; One side moves the distance of regulation at the Width of bag roughly at every turn; Stop at the stop position of regulation successively, one side is carried in the scope of regulation, the intermittent delivery formula longitudinal type pack packing method that the packing of in its course of conveying, implementing to stipulate is handled.In more detail, relating to the packed article that comprises fraction is the intermittent delivery formula longitudinal type pack packing method of object.
Background technology
One in the longitudinal type pack packing of intermittent delivery formula is the filling that comprises the packed article of fraction.Use Fig. 1,2, in the past this intermittent delivery formula longitudinal type pack packing method is described.In the past; For the filling packed article makes the clip 104,104 of the both side edges portion 108 of controlling bag 106 approaching each other; Make sack 110 to become the mode opening of circular; The front elevation of the bag 106 of the state that Fig. 1 has represented to make sack 110 openings is when (a) conveying after the expression filling fraction 136 begins, when (b) conveying on the next stop position of expression stops.Birds-eye view (corresponding) when the conveying of the bag 106 of the state that Fig. 2 has represented to make sack 110 openings stops with Fig. 1 (b).The arrow in left side is represented the throughput direction of bag 106 among Fig. 2.
As shown in the figure; In intermittent delivery formula longitudinal type pack packing, because one side delivery bag 106 off and on, the packing that one side is stipulated is handled; So; When carrying (carry when stopping in when especially intermittent delivery begins and gap), be filled in the interior fraction 136 of bag because of inertia significantly waves, at edge portion 108 bulk depositions (referring to Fig. 1) of sack 110.Its result is that fraction 136 as reason, produces poor sealing (sealing of nipping) attached to the sealing reservations of the inner face of sack 110 in the sealing process afterwards.In addition, waving under the excessive situation, also producing fraction 136 from the sack 110 such problem (referring to Fig. 1 (b), Fig. 2) outside the bag that flies out.
,, carried out after filling fraction 136 as the relative strategy of such problem in the past, as shown in Figure 3 before sack 110 sealing, pair of right and left clip 104 is deviated from, make bag 106 slack-free methods at the downside of sack 110.Fig. 3 represent tensioning bag 106 the front elevation of state, when (a) beginning was carried in expression, (b) expression was carried when stopping.But, though according to this method, can prevent fraction 136 from sack 110 problem outside the bag that flies out,, can not suppress the accumulation in the edge portion 108 of bag 106 of waving, accompanying with it of the fraction 136 in the bag itself.And; If fraction 136 because of wave with bag in tensioned portion 118 under sharp impacts, even then be tensioned near the sack 110, fraction 136 also is immersed in the minim gap of the inner face of sack 110; As a result, can produce attached to the situation that seals reservations.
Especially; Under the situation between the operation of operation that the for example such stop position at intermittence of degassing process is set in filling fraction 136 and sealing sack 110; From after the filling fraction till the sealing of carrying out sack 110 during, repeatedly carry out the beginning of intermittent delivery repeatedly and stop.Promptly, after the filling fraction because to the beginning of the intermittent delivery of next operation and stop, fraction 136 is significantly waved, wave at it and just to carry out to the beginning of the intermittent delivery of next operation when also not being absorbed and stop.Thus, the cumulative bad ground that waves of fraction 136 increases, and when sealing sack 110, the problem of above-mentioned poor sealing is obvious.
In addition; Even suppose fraction 136 no shows sealing reservations; Be arranged at the degassing process that will pressurize under the situation of back operation because the air that is pushed out in the bag through the pressurization degassing, make the fraction 136 that is immersed in tensioned portion 118 by on shift the sealing reservations onto; Its result is to produce poor sealing.Like this, near making sack 110 in the slack-free method, owing to can not prevent the generation of above-mentioned poor sealing fully; So the past is through reduce the speed that packing is handled, suppress the next correspondence of waving of fraction 136 as far as possible; But, do not avoid the productive reduction that causes because of inhibition speed.
But,, the anti-rolling pendulum device of TOHKEMY 2001-88810 communique (patent documentation 1) record is for example arranged as the invention of waving that prevents the charges in the intermittent delivery formula longitudinal type pack packing.In this device, adopt through living with a pair of anti-rolling pendulum plate holder the structure that the rolling of the bag that prevents in the intermittent delivery process, to produce is put by anchor clamps each with each bag of hanging state and keeping.
This device is owing to suppress waving of bag itself through directly going into bag with plate holder, so, can expect certain effect, still, that can not reduce packed article waves itself.Especially be under the situation of fraction at packed article, can not suppress waving of these aqueous charges basically, even owing to use this structure also can produce poor sealing, so, have to suppress to pack the speed of processing.

In addition; Though the invention of patent documentation 2,3 record is non-directly to the invention of the problems referred to above point, disclose as after a structure part, that the pair of right and left clip of clamping bag is set in the position more approaching of the application of stating structure of inventing than general position.But the invention of these document records is compared with the application's invention, makes the approaching moment of clip different, and the solution problem of invention and effect are also different.
The application's invention is the invention that is used to solve above-mentioned problem points in the past; More particularly; Its problem is; Provide a kind of prevent by the fraction in the bag of intermittent delivery outside bag, fly out, the generation of poor sealing of bag, can improve the productive intermittent delivery formula longitudinal type pack packing method that packing is handled.
Summary of the invention
But, though above-mentioned fraction to wave with the force of inertia that accompanies with intermittent delivery be that this point of cause is very clear; If in addition; Also there is other essential factor of waving of encouraging fraction, then, can reduces waving of fraction through it is removed; And then can prevent the generation of the flying out of fraction, poor sealing, can also seek the stabilization of degassing phase, productive raising.Therefore, the inventor has carried out various tests according to above-mentioned design, and the result finds as the essential factor of waving of encouraging fraction, and the opening shape relation of the sack of the throughput direction of bag when overlooking is very big.
Promptly, usually the opening shape of bag is considered the insertion of hopper, fraction filling nozzle, the clip of making about making is approaching, circular when overlooking (referring to Fig. 1,2).In this case; Can find out from figure; It is sharp-pointed with angle θ that bag 106 becomes when overlooking the boundary portion 112 at side seal, expands the shape of opening towards the Width center side, under the situation about seeing in the cross section that with the Width with respect to paper and bag 106 is the right angle; The closer to the edge portion 108 of the Width of bag 106, sectional area is more little.Under this open state, bag 106 is carried at its Width, when seeing situation about for example having stopped, fraction 136 integral body in the bag move to the boundary portion 112 of the side seal on right side in Fig. 1 (b), Fig. 2 because of inertia, shown in Fig. 1 (b), bulk deposition.
Even such shown in the image pattern 3; Make the bag 106 tensionings situation under; From its tensioned portion 118 to the scope of the packed article that is filled with downside, though obvious unlike the situation that kind of Fig. 1, also become the shapes that the encapsulation boundary portion 112 in the edge portion 108 of bag 106 sharply opens towards central portion; Still near edge portion 108, sectional area is little.Therefore, cause and the identical phenomenon of situation that bag 106 carried, stopped at its Width.
The application's invention is the invention of making according to above-mentioned knowledge; A kind of packing method is provided; This packing method is by the both side edges portion of bag being controlled to hang state by the pair of right and left hold assembly of intermittent delivery along the track of regulation; One side makes above-mentioned bag move the distance of regulation at the Width of bag roughly at every turn; Stop at the stop position of regulation successively; One side is carried in the scope of regulation; Carry out the intermittent delivery formula longitudinal type pack packing method that the packed article to comprising fraction that various packings handle is packed in the process that in stopping at the process of above-mentioned stop position or between above-mentioned stop position, moves; It is characterized in that; Above-mentioned packing method comprises to the pair of right and left hold assembly that is positioned at deviation location to be supplied with empty bag and bag supply operation that makes it to control, makes above-mentioned a pair of hold assembly be close to first approximated position; Make the opening operation of the sack opening of above-mentioned bag, from above-mentioned opening sack filling fraction in above-mentioned bag the fraction filling procedure, above-mentioned hold assembly is deviated from each other, make the slack-free tensioning operation of above-mentioned bag, with the sack leak free sealing process of above-mentioned bag, above-mentioned packing method also be included in above-mentioned fraction filling procedure near finish or end after; Make above-mentioned a pair of hold assembly move to second narrower than the above-mentioned first approximated position at interval approximated position; Make above-mentioned sack become the Width of above-mentioned bag when overlooking be minor axis substantially elliptical near operation, keep the state of above-mentioned substantially elliptical at above-mentioned sack, the opening that above-mentioned bag carries stop position to carry to the next one as the opening of one of stop position of afore mentioned rules is carried operation, above-mentioned tensioning operation and sealing process are above-mentionedly carried out after near operation and opening conveying operation having carried out.In this intermittent delivery formula longitudinal type pack packing method; Through the approximated position of hold assembly being set for so extremely simple method of two stages; Can reduce by the waving of fraction in the bag of intermittent delivery, can suppress fraction flying out to bag outside, bag the generation of poor sealing.

The specific embodiment
With reference to Fig. 4 to 7, the application's working of an invention mode is described.At first, use Fig. 4, the single-piece structure of the application's invention is described.Fig. 4 is the schematic configuration diagram of the intermittent delivery formula longitudinal type pack wrapping machine (following single wrapping machine of claiming) 1 of the packing method of the relevant the application's invention of enforcement.In addition, in this embodiment, be with solid 34 and fraction 36 the two to bag 6 fillings, still, also can be the situation of only filling fraction 36.
Wrapping machine 1 possesses the rotary table 2 that rotates off and on through the direction of the not shown drive source arrow in the drawings that goes out.On this rotary table 2, as the switching of hold assembly pair of right and left clip 4 freely, in rotary table 2 rotations, move with the many groups of arranged spaced of regulation.Clip 4 is as shown in the figure, with filling the bag 6 of packed article 34,36 control to hang state in its both side edges portion (side seal) 8, be accompanied by the rotation of rotary table 2, delivery bag 6.Clip 4 is made in the Width contact of bag 6 and is left structure freely.Below, each operation of handling in conjunction with packing describes the structure of wrapping machine 1.
Symbol I is that empty bag is supplied with operation, at this stop position and this operation known transmission charging tray 20 is set accordingly.In transmitting charging tray 20, by emit roller 22 with bag 6 in order many emit, by a pair of bag taking-up sucker 24 bag 6 is taken out, that kind shown in the arrow makes it to become plumbness in the image pattern, delivers to the clip 4 that in this operation, stops also standby.
Then, will be carried to lettering operation II by the bag 6 that clip 4 is controlled, by information such as printing device 26 lettering build dates.Operation III is a sack opening operation; After being adsorbed onto bag face 16 from both sides near by the sack 10 of the pair of openings sucker 28 that is arranged on this stop position at bag 6; One side deviates from this pair of openings sucker 28; Clip 4 about one side makes is approaching at the Width of bag 6, and making sack 10 openings is circular.With the position of left and right sides clip 4 of this moment as first approximated position.This open state remains to next operation IV by the openings lead device 30 that chases after from formula always.
Operation IV is the solid filling procedure, through hopper 38 to kept by openings lead device 30 open state the bag 6 filling solids 34.Operation V is that fraction filling and clip are near operation; Through nozzle 40 to bag 6 filling fraction 36 (referring to Fig. 5,6,7); In its stowing operation, after (especially final) or the filling, make pair of right and left clip 4 further approaching, move to the position of regulation from above-mentioned first approximated position.With the position of left and right sides clip 4 of this moment as second approximated position.To set forth in the back this.In addition, in this embodiment, the filling of fraction 36 is in the process that rotary table 2 stops, carrying out, and still, also can in the process of rotary table 2 rotations, carry out.
The state that the sack 10 that bag 6 is kept above-mentioned that kind is opened is transferred to the stop position of carrying out operation VI.Operation VI is sack tensioning and pressurization degassing process; If bag 6 stops at the stop position of carrying out operation VI; Then at first; The left and right sides clip 4 that is positioned at second approximated position at operation V is deviated from,, form tensioned portion 18 (referring to Fig. 7) in the position of the top of comparing with the packed article (solid 34 and fraction 36) of bag 6 until the place that applies certain tensile force to bag 6.After this,, the gas in the bag is released outside bag, in view of the above, outgased by the bag face 16 of a pair of bar-shaped pressure-producing part 42 cramping bag 6 from both sides.In addition, pressure-producing part 42 is not limited to bar-shaped parts, also can use tabular parts.Because when rotary table 2 having been stopped in order to carry out operation VI, as after state waving of fraction 36 in the bag significantly suppressed, so, the degassing of can under stable status, pressurizeing.
Operation VII, VIII are sack first sealing process, sack second sealing process of carrying out at separately stop position, use a pair of first hot plate 44, the second hot plate 46 position seals sack 10 in regulation respectively.Operation IX is that sealing cooling and goods are emitted operation, at operation VII, VIII, by a pair of cold plates 48 coolant seals the position, accomplish packing.After accomplishing, bag 6 is discharged along skewed slot 50 as the article of completion.Operation X is that bad bag is discharged operation.
Then,, explain from operation V that VI is to VII, the action of the conveying of the bag 6 between the various stop position when implementing operation and the clip 4 that accompanies with it to VI with reference to Fig. 5 to 7.Fig. 5 is the figure of shape variation of action and the sack 10 of the clip 4 among the expression operation V.Promptly, operation V as stated; Be the operation of filling fraction 36, about clip 4 be positioned at above-mentioned first approximated position, the bag 6 its sacks 10 shown in Fig. 5 (a); State to become circular is transferred from the stop position of carrying out previous operation IV, stops at this stop position.And, nozzle 40 is inserted filling fraction 36 to sack 10.Then, in the process of filling fraction 36, in the time of especially during the sand off or after the sand off, the clip 4 about making each other near moving, shown in Fig. 5 (b), is positioned at above-mentioned second approximated position once more.At this moment, the both side edges portion 8 of bag 6 is in sack 10 sides, in the moment and scope of the obstruction of moving that can not become nozzle 40; Further approaching each other; Bag face 16 separately is in Fig. 5 (b), and convex ground distortion up and down is across side seal boundary portion 12 separately; About the part of (about among Fig. 5) be big obtuse angle θ, become and also can be described as roughly flat shape.Promptly, to become the Width of bag 6 when overlooking be the substantially elliptical of minor axis to sack 10.
Fig. 6 representes that sack 10 keeps above-mentioned state; The state that is transferred to the stop position of carrying out next VI from the stop position of carrying out operation V; When (a) beginning was carried in expression, (b) (will keep sack 10 substantially ellipticals here, opened when stopping in expression; The operation that bag 6 is carried to next stop position is called opening and carries operation, is called opening and carries stop position keeping stop position that bag 6 that this opening is transferred stops).Because bag 6 throughput direction is the Width of bag roughly, so, with example is same in the past, produce waving on the Width of fraction 36.But as stated, bag 6 is the substantially elliptical that its Width is a minor axis, is state that we can say almost parallel along two faces of major axis, and interval therebetween is roughly the same along long axis direction.Therefore, in bag in Fig. 6 (a) to the left, the fraction 36 of in Fig. 6 (b), moving to the right under situation about seeing from Fig. 5 (b), along the long axis direction approximate equality move, do not exist as example was to the nearby concentrated situation of side seal boundary portion 12 in the past.Therefore, its piling height also significantly reduces.
Here, the essential factor of inhibition fraction 36 accumulations also has one.Promptly, be the inclined degree of edge portion 8 sides of bag 6.Can know from Fig. 6, the Width center side that bag 6 edge portion 8 sides become sack 10 side direction bags 6 significantly near, compare it with example in the past and tilt greatly, the state to the upside overspread of fraction 36 in view of the above, suppresses fraction 36 and piles up along the bag inner faces.As shown in the figure, 36 of fraction are stacked into the position of comparing enough belows with the position of being controlled by clip 4, can not arrive by clip 4 slack-free tensioned portion 18 (referring to Fig. 7).At this operation VI as stated, make clip 4 away from, with the sealing reservations compare below position (tensioned portion 18), make the bag 6 tensionings; After this degassing of pressurizeing, still, as stated; Because the waving of the fraction 36 during bag 6 stop, pile up and be suppressed lowly, so, the degassing operation of can stably pressurizeing; In addition, through the degassing of pressurizeing, fraction 36 can not move to the sealing reservations yet adheres to.
Fig. 7 be expression bag 6 from the stop position (opening conveying stop position) of carrying out operation VI figure, when (a) beginning is carried in expression, when (b) expression stops to the feed status of the stop position of carrying out VII.As stated, during stopping on operation VI executing location, waving of fraction 36 is suppressed lowly, and then in stopped process, it waves by further absorption in operation VI executing location.Therefore, even wave when VII carries, producing from operation VI, can be not overlapping with waving of producing of front yet, become big waving.Therefore, do not exist fraction 36, in the sealing operation that this operation VII carries out, produce the situation of poor sealing attached to the sealing reservations.
Like this; Needn't in the wrapping machine 1 of this embodiment, append special part; Only be set at so extremely simple structure of two stages, can suppress the generation of poor sealing, can improve the productivity that packing is handled through approximated position with pair of right and left clip 4.
In addition; In this embodiment; The moment of moving (clip is near operation) to second approximated position of clip 4 is set in packed article in bag 6 stowing operations or after the filling, but comprises also that wherein bag 6 carries out stop position from the fraction filling procedure and carry out the process that stop position carries to next operation.If with bag 6 before next operation is carried, set clip near operation, then can reduce the waving of fraction 36 in the bag effectively.But; Waving in allowed band of fraction 36 when intermittent delivery begins; Under the preferential such situation of the productivity that packing is handled; Through in the course of conveying of next operation, setting clip near operation at bag 6, can shorten clip 4 moves standing time at intermittence from the amount of needed time to second approximated position, can improve the productivity that packing is handled.
In addition; In this embodiment; To set with the pressurize mode of degassing process of the same stop position at intermittence of sack tensioning operation; But also can be with the stop position at intermittence in the sealing process (being the sack first sealing process VII in this embodiment) of sack 10, the mode of before the sealing of sack 10, carrying out is set.
