Description
Technical field
The present invention relates to by the edge, both sides possessing the opening and closing pair of right and left clip clamping bag of holding part freely respectively of track (such as circle, straight line, the racing track etc.) intermittent movement along regulation in horizontal surface, this bag is kept with hanging state, one side is in the distance of the Width mobile regulation at every turn of roughly bag, stop at the stop position of regulation successively, one side, in the scope conveying of regulation, implements the intermittent delivery formula longitudinal type pack packing method of the packaging process specified in its course of conveying.In more detail, the intermittent delivery formula longitudinal type pack packing method that the packed article relating to comprising fraction is object.
Background technology
Longitudinal type one of packing in packaging of intermittent delivery formula is the filling of the packed article comprising fraction.Use Fig. 1,2, this intermittent delivery formula longitudinal type pack packing method is in the past described.In the past, the clip 104 of the edge, both sides 108 of holding bag 106,104 close to each other is made for filling packed article, make sack 110 to become the mode opening of circular, Fig. 1 represents the front elevation of the bag 106 of the state making sack 110 opening, when conveying a () represents filling fraction 136 after starts, when (b) represents that the conveying on next stop position stops.Fig. 2 represents the birds-eye view (corresponding with Fig. 1 (b)) during the conveying stopping of the bag 106 of the state making sack 110 opening.In Fig. 2, the arrow in left side represents the throughput direction of bag 106.
As shown in the figure, in intermittent delivery formula longitudinal type pack packaging, due to one side delivery bag 106 off and on, one side carries out the packaging process specified, so, when carrying (when the conveying of when especially intermittent delivery starts and gap stops), the fraction 136 be filled in bag is significantly waved because of inertia, in the edge 108 bulk deposition (see Fig. 1) of sack 110.Its result is, fraction 136 is attached to the sealing reservations of the inner face of sack 110, as reason, produces poor sealing (sealing of nipping) in sealing process afterwards.In addition, when waving excessive, also producing fraction 136 and flying out problem (see Fig. 1 (b), Fig. 2) such bag from sack 110.
In the past, as the relative strategy of such problem, carry out after filling fraction 136, before sack 110 seals, as shown in Figure 3, pair of right and left clip 104 is deviated from, makes the method for bag 106 tensioning in the downside of sack 110.Fig. 3 represents the front elevation of the bag 106 of the state of tensioning, when (a) represents that conveying starts, when (b) represents that conveying stops.But, although according to the method, the problem that fraction 136 flies out bag from sack 110 can be prevented, the accumulation on the edge 108 of bag 106 of waving, accompanying with it of the fraction 136 in bag itself can not be suppressed.And, if fraction 136 because waving with the tensioned portion 118 in bag immediately below sharp impacts, even if be then tensioned near sack 110, fraction 136 is also immersed in the minim gap of the inner face of sack 110, as a result, the situation being attached to sealing reservations can be produced.
Especially, when interval stop position such for such as degassing process being set between the operation of filling fraction 136 and the operation of sealing sack 110, during after filling fraction to carrying out the sealing of sack 110, repeatedly repeatedly carry out beginning and the stopping of intermittent delivery.Namely, after filling fraction, due to beginning and the stopping of the intermittent delivery to next operation, fraction 136 is significantly waved, and just carries out the beginning to the intermittent delivery of next operation and stopping when it waves and is not also absorbed.Thus, waving of fraction 136 increases cumulatively, and when sealing sack 110, the problem of above-mentioned poor sealing is obvious.
In addition, even if suppose that fraction 136 does not arrive sealing reservations, when after pressurization degassing process is arranged on when operation, owing to passing through the degassed air be pushed out in bag of pressurization, the fraction 136 being immersed in tensioned portion 118 is made to be pushed sealing reservations, its result is, produces poor sealing.Like this, in the method making tensioning near sack 110, due to the generation of above-mentioned poor sealing can not be prevented completely, so, be the speed by the process of reduction packaging in the past, suppress waving of fraction 136 next corresponding as far as possible, but, do not avoid the productive reduction because suppression speed causes.
But, as the invention of waving preventing intermittent delivery formula longitudinal type from packing the charges in packaging, such as, have the anti-rolling pendulum device that Japanese Unexamined Patent Publication 2001-88810 publication (patent documentation 1) is recorded.In this device, adopting each of each bag by firmly being kept with hanging state by fixture with a pair anti-rolling pendulum plate holder, preventing the structure that the rolling of the bag produced in intermittent delivery process is put.
This device suppresses waving of bag itself owing to entering bag by direct plate holder, so, certain effect can be expected, but that can not reduce packed article waves itself.Especially, when packed article is fraction, substantially waving of these aqueous charges can not be suppressed, even if owing to using this structure also can produce poor sealing, so, the speed suppressing packaging to process of having to.

Detailed description of the invention
With reference to Fig. 4 to 7, the embodiment of the present application is described.First, use Fig. 4, the structure of the entirety of the present application is described.Fig. 4 is the schematic configuration diagram of intermittent delivery formula longitudinal type pack wrapping machine (singly claiming wrapping machine below) 1 implemented about the packing method of the present application.In addition, in the present embodiment, be by both solid 34 and fraction 36 to bag 6 filling, but, also can be the situation of only filling fraction 36.
Wrapping machine 1 possesses the rotary table 2 rotated off and on by the direction of not shown drive source arrow in the drawings.On this rotary table 2, configure the many groups of opening and closings as hold assembly pair of right and left clip 4 freely using the interval specified, move while rotary table 2 rotates.The bag 6 being filled with packed article 34,36 as shown in the figure, holds to hang state in its edge, both sides (side seal) 8, the delivery bag 6 along with the rotation of rotary table 2 by clip 4.Clip 4 is made and is left structure freely in the Width contact of bag 6.Below, in conjunction with each operation of packaging process, the structure of wrapping machine 1 is described.
Symbol I is empty bag supply step, arranges known transmission charging tray 20 accordingly at this stop position and this operation.Transmission charging tray 20 in, by releasing roller 22 bag 6 is released in order a sheet by a sheet, by a pair bag of taking-up sucker 24, bag 6 is taken out, as in figure shown in arrow make it to become plumbness, in this operation stop and standby clip 4 deliver.
Then, the bag 6 held by clip 4 is carried to lettering operation II, by information such as printing device 26 lettering build dates.Operation III is sack opening operation, after being adsorbed onto bag face 16 from both sides by the pair of openings sucker 28 being arranged on this stop position near the sack 10 of bag 6, one side makes this pair of openings sucker 28 deviate from, one side makes the clip 4 of left and right close at the Width of bag 6, makes sack 10 opening be circular.Using the position of left and right clip 4 now as the first approximated position.This open state remains to next operation IV by the openings lead device 30 chased after from formula always.
Operation IV is solid filling procedure, through hopper 38 to the bag 6 filling solid 34 being maintained open state by openings lead device 30.Operation V is that fraction filling and clip are closest to operation, through nozzle 40 to bag 6 filling fraction 36 (see Fig. 5,6,7), in its stowing operation after (especially final) or filling, make pair of right and left clip 4 close further from above-mentioned first approximated position, move to the position of regulation.Using the position of left and right clip 4 now as the second approximated position.To set forth below this.In addition, in this embodiment, the filling of fraction 36 carries out in the process of rotary table 2 stopping, but, carry out in the process that also can rotate at rotary table 2.
The state that bag 6 maintenance sack 10 as described above is opened is transferred to the stop position performing operation VI.Operation VI is sack tensioning and pressurization degassing process, if bag 6 stops at the stop position performing operation VI, then first, the left and right clip 4 being positioned at the second approximated position at operation V is deviated from, until apply the place of certain tensile force to bag 6, form tensioned portion 18 (see Fig. 7) in the position of the top compared with the packed article (solid 34 and fraction 36) of bag 6.After this, clamped the bag face 16 of bag 6 by a pair bar-shaped pressure-producing part 42 from both sides, by extrapolated to bag for the gas in bag, accordingly, carry out degassed.In addition, pressure-producing part 42 is not limited to bar-shaped parts, also can use the parts of tabular.Because in order to perform operation VI rotary table 2 be stopped time, waving of the fraction 36 as aftermentioned in bag is significantly suppressed, so, pressurization can be carried out at steady-state degassed.
Operation VII, VIII are sack first sealing process, sack second sealing process that perform at respective stop position, and use a pair first hot plate 44, second hot plates 46 are at the position seals sack 10 of regulation respectively.Operation IX is that sealing cooling and goods release operation, and at operation VII, VIII, the position by a pair cold plates 48 coolant seal, completes packaging.After completing, bag 6 is discharged as finished goods along skewed slot 50.Operation X is that operation discharged by bad bag.
Then, with reference to Fig. 5 to 7, illustrate from operation V to VI, VI to VII, the conveying of the bag 6 between various stop position during enforcement operation and the action of clip 4 of accompanying with it.Fig. 5 is the figure of the change of the action of the clip 4 represented in operation V and the shape of sack 10.Namely, operation V is described above, be the operation of filling fraction 36, the clip 4 of left and right is positioned at above-mentioned first approximated position, and its sack 10 of bag 6 is as shown in Fig. 5 (a), be transferred from the stop position performing previous operation IV with the state becoming circular, stop at this stop position.And, nozzle 40 is inserted to sack 10, filling fraction 36.Then, in the process of filling fraction 36, time especially during sand off or after sand off, make clip 4 movement close to each other again of left and right, as shown in Fig. 5 (b), be positioned at above-mentioned second approximated position.Now, the edge, both sides 8 of bag 6 is in sack 10 side, within moment of obstruction of movement that can not become nozzle 40 and scope, mutually close further, respective bag face 16 is in Fig. 5 (b), and upper and lower convex ground distortion, across respective side seal boundary portion 12, the part of left and right () is large obtuse angle θ in Fig. 5 up and down, and becoming is alternatively generally flat shape.Namely, sack 10 becomes the Width of bag 6 when overlooking is the substantially elliptical of minor axis.
Fig. 6 represents the state that sack 10 remains above-mentioned, from the state that the stop position performing operation V is transferred to the stop position performing next VI, when () represents that conveying starts a, when () expression stops b (here, maintenance sack 10 substantially elliptical is opened, bag 6 being called opening conveying operation to the operation that next stop position is carried, being called opening conveying stop position by maintain the stop position that bag 6 that this opening is transferred stops).Throughput direction due to bag 6 is the Width of roughly bag, so, same with past case, produce waving on the Width of fraction 36.But as mentioned above, bag 6 is the substantially elliptical of minor axis in its Width, and two faces along major axis are almost parallel state, and interval is therebetween roughly the same along long axis direction.Therefore, in bag in Fig. 6 (a) to the left, the fraction 36 of moving to the right in Fig. 6 (b) is when seeing from Fig. 5 (b), move substantially uniformly along long axis direction, do not exist as past case to the situation that side seal boundary portion 12 is nearby concentrated.Therefore, its piling height also significantly reduces.
Here, the essential factor suppressing fraction 36 to be piled up also has one.Namely, be the inclined degree of side, edge 8 of bag 6.As can be seen from Figure 6, the Width center side that the side, edge 8 of bag 6 becomes sack 10 side direction bag 6 is significantly close, and it tilts large compared with past case, to the state of the upside overspread of fraction 36, accordingly, suppresses fraction 36 to be piled up along bag inner face.As shown in the figure, fraction 36 is only stacked into the position of enough belows compared with the position held by clip 4, can not arrive by the tensioned portion 18 (see Fig. 7) of clip 4 tensioning.Described above at this operation VI, make clip 4 away from, at the position (tensioned portion 18) of the below compared with sealing reservations, make bag 6 tensioning, after this pressurization is carried out degassed, but, as mentioned above, because the waving of the fraction 36 during the stopping of bag 6, pile up suppressed must be low, so, stably can carry out degassed operation of pressurizeing, in addition, degassed by carrying out pressurization, fraction 36 also can not move attachment to sealing reservations.
Fig. 7 be represent bag 6 from the stop position (opening conveying stop position) performing operation VI to the figure of feed status of stop position performing VII, when (a) represents that conveying starts, (b) represents when stopping.As mentioned above, during stopping in operation VI executing location, fraction 36 wave suppressed must be low, and then in operation VI executing location in stopped process, it waves and is absorbed further.Therefore, wave even if produce when carrying from operation VI to VII, also can not be overlapping with waving of producing above, become large waving.Therefore, there is not fraction 36 and be attached to sealing reservations, in the sealing operation that this operation VII carries out, produce the situation of poor sealing.
Like this, special part need not be added in the wrapping machine 1 of present embodiment, by means of only the approximated position of pair of right and left clip 4 being set as the extremely simple structure that two benches is such, the generation of poor sealing can being suppressed, the productivity of packaging process can be improved.
In addition, in the present embodiment, the moment of the movement to the second approximated position (clip is closest to operation) of clip 4 is set in packed article in bag 6 stowing operation or after filling, but wherein also comprises bag 6 from fraction filling procedure execution stop position to the process that next operation execution stop position is carried.If before being carried to next operation by bag 6, setting clip closest to operation, then can reduce waving of the fraction 36 in bag effectively.But, fraction 36 when intermittent delivery starts wave in allowed band, the productivity of packaging process is preferential under such circumstances, by setting clip closest to operation in the course of conveying of bag 6 to next operation, clip 4 moves interval standing time from the amount of required time to the second approximated position can be shortened, the productivity of packaging process can be improved.
In addition, in the present embodiment, set in the mode of the degassing process that carries out at the interval stop position same with sack tensioning operation pressurizeing, but also can with the interval stop position in the sealing process (being sack first sealing process VII in the present embodiment) of sack 10, the mode of carrying out before the sealing of sack 10 sets.
