Vertical filling-packaging machine 101 comprises: the film feed roller 107 that is used for transporting cylindrical membrane 160 downwards; Be used for weighting material is imported the guiding nozzle 108 of cylindrical membrane 160; A pair of ironing roller 125, it is used for cylindrical membrane 160 is squeezed into even shape to form flat 160a; Transverse sealing mechanism 130, it is used for the Width heat seal flat 160a along cylindrical membrane 160; With the cutting mechanism 140 that comprises cutter 141, it is used for cutting by transverse sealing mechanism 130 thermosealed transverse sealing parts.The distance of direction (vertical direction shown in Figure 1) between transverse sealing mechanism 130 and cutting equipment 140 that is transported along cylindrical membrane 160 wherein is set to corresponding to the length with a manufactured packaging bag.About this point, the heat seal operation that heat seal mechanism 130 carries out also is known as " transverse sealing ".
Adopt the example operation of the vertical filling-packaging machine 101 that this mode constructs to be described with reference to Fig. 2.
In the state shown in Fig. 2 A, a pair of ironing roller 125, transverse sealing mechanism 130 and cutting mechanism 140 stay open state.In addition, a packaging bag 166 has been formed on cylindrical membrane 160 times.From guiding nozzle 108, weighting material just is being inducted into cylindrical membrane 160 (referring to Fig. 1) continuously.
Next, shown in Fig. 2 B, when the height of weighting material surpassed the position of ironing roller 125, cylindrical membrane 160 was clamped to separate weighting material by ironing roller 125.
Next, shown in Fig. 2 C, under cylindrical membrane 160 kept clamped situation, ironing roller 125 was actuated to rotation, thereby cylindrical membrane 160 is transported downwards, forms the flat 160a in the cylinder 160 simultaneously.Thisly transport operation and continued, the transverse sealing part 165 that is heat sealed up to step formerly arrives it and is cut the be clipped in the middle position at place of mechanism 140.
Next, shown in Fig. 2 D, when transporting of cylindrical membrane 160 stopped, transverse sealing mechanism 130 and cutting mechanism 140 were driven.Transverse sealing mechanism 130 clamps and forms flat 160a by a pair of ironing roller 125, forms transverse sealing part 165 with the Width along cylindrical membrane 160.Cutting mechanism 140 is clamped in the transverse sealing part 165 that is heat sealed in the previous steps successively, wherein still has the transverse sealing part 165 of heat with cooling, and cutter 141 is advanced with broad ways cutting transverse sealing part 165.Adopt this mode, packaging bag 166 is cut off from cylinder film 160.
Next, shown in Fig. 2 E, make a pair of ironing roller 125, transverse sealing mechanism 130 and cutting mechanism 140 all enter open mode.By opening cutting mechanism 140, the hold mode of cutting mechanism 140 is released so that a packaging bag 166 to be provided.
Then, film feed roller 107 (referring to Fig. 1) is actuated to transport once more cylindrical membrane 160, up to the state shown in Fig. 2 A occurring.By repeating series of steps as mentioned above, filling the packaging bag 166 of weighting material and made in proper order.
After using transverse sealing mechanism 130 to form transverse sealing part 165 by this way in cylindrical membrane 160, the vertical filling-packaging machine 101 of Fig. 1 transports cylindrical membrane 160 once more downwards, and by using cutting mechanism 140 coolings and cutting transverse sealing part 165.
For example, Japanese Patent proposes a kind of mechanism No. 2598879, and it can carry out the operation of heat seal, cooling and cutting cylinder film 160 fully when transporting of film stops.
Fig. 3 is used to describe conventional seals and the structure of cutting mechanism and the diagrammatic sketch of operation that Japanese Patent the 2598879th proposes.
As shown, transverse sealing and cutting mechanism 230 comprise: heating pole 201 and heating pole container 204, and it is used for along the flat 160a of its Width heat seal cylindrical membrane; And comprise: cooling rod 202 and cutting equipment 205, it is used for cooling and cuts by heating pole 201 and heating pole container 204 thermosealed transverse sealing parts.
Heating pole 201 and cutting equipment 205 be by the drive power source of for example air cylinder, and be configured to move forward and backward along the direction perpendicular to flat 160a.Cooling rod 202 and heating pole container 204 be successively respectively by pivot shaft 210a, the rotatable support of 210b; And be configured in the step of moving that moves forward and backward of heating pole 201 and cutting equipment 205, center on pivot shaft 210a, 210b rotatably moves.Particularly, as shown in Figure 3A, when heating pole 201 advances, at this moment cooling rod 202 does not contact with flat 160a; And shown in Fig. 3 B, when heating pole 201 retreats, at this moment cooling rod 202 contacts with flat 160a.Successively, as shown in Figure 3A, when cutting equipment 205 was return, heating pole container 204 contacted with flat 160a; And shown in Fig. 3 B, when cutting equipment 205 advanced, heating pole container 204 did not contact with flat 160a.
As shown in Figure 3A, by using heating pole 201 and heating pole container 204, Gou Zao transverse sealing and cutting mechanism 230 advance heating pole 201 and cutting equipment 205 are retreated flat 160a being exerted pressure and heat as mentioned above, thereby heat seal flat 160a is to form the transverse sealing part.Then, shown in Fig. 3 B, heating pole 201 is return, and cutting equipment 205 advances so that flat 160a is clipped in the transverse sealing part that wherein still has heat between cutting equipment 205 and the cooling rod 202 with cooling.After this cooling down operation executed schedule time, the cutter 203 that is provided with in cutting equipment 205 advances with the transverse sealing part of cutting cooling.

After carrying out the heat seal operation, the vertical filling-packaging machine 101 shown in Fig. 1 transports cylindrical membrane once more downwards, arrives the height of cutting mechanism 140 up to the transverse sealing part 165 of formation like this.Therefore, consider the variation of the amount of presenting cylindrical membrane, must use big sealed width.Yet, when using transverse sealing and cutting mechanism 230, owing to need not to consider this variation can reduce sealed width.Big sealed width means the cylindrical membrane that use is extra, causes packaging bag to increase as the manufacturing cost of product.Next, as mentioned above,, therefore, can carry out the packaging bag manufacturing operation with more speed ground because therefore transverse sealing and cutting mechanism 230 need not to transport cylindrical membrane downwards, and can reduce heat seal, cooling and cutting operation required time.
Other example operation of vertical filling-packaging machine 101 is described with reference to Fig. 4.
At first, shown in Fig. 4 A, the weighting material of bootstrap nozzle 108 is packed into the cylindrical membrane 160 that its lower end is heat sealed.As shown, the packaging bag that the lower end of cylindrical membrane 160 is positioned at the manufacturing of fwd manufacturing step is cut off the position at place, and at the height place identical with the blade of cutter 141.In addition, the regional A that will will be heat sealed in the transverse sealing step that describes later is positioned at above the ironing roller 125.
Next, shown in Fig. 4 B, cylindrical membrane 160 is transported downwards, drops on the ironing roller 125 times up to the level of weighting material.
Next, shown in Fig. 4 C, in the zone on the height of weighting material, cylindrical membrane 160 is clamped by a pair of ironing roller 125, and ironing roller 125 is actuated to rotation.Therefore, cylindrical membrane is transported downwards, forms flat 160a simultaneously.Thisly transport operation and be performed, arrive the height of transverse sealing mechanism 130 up to the regional A that will be heat sealed.
Subsequently, use heat seal mechanism 130 along its Width heat seal cylindrical membrane 160, cylindrical membrane 160 is transported downwards once more, and uses cutting mechanism 140 to cut off cylindrical membrane 160, thereby makes a packaging bag.
Summary of the invention
The present invention is with the problem that solves
Yet though use as shown in Figure 3 transverse sealing and cutting mechanism 230 that aforesaid advantage is provided, transverse sealing mechanism must be become individual unit by overall package for this purpose with cutting mechanism.Because this requirement causes the restriction to the shape of heating pole 201 and cooling rod 202, for example changing in the heating pole 201 and can encounter difficulties with the heating pole of another kind of type.In making packaging bag, in some cases, depend on the shape of manufactured packaging bag and the material heating bar 201 and the cooling rod 202 of cylindrical membrane must be exchanged.Therefore, expectation be: this vertical filling-packaging machine is configured so that: consider the ability of polytype packaging bag of make adopting multiple contour shape, polytype heating pole 201 and cooling rod 202 can be installed in wherein.
On the other hand, as mentioned above, do not transport cylindrical membrane, use transverse sealing and cutting mechanism 230 fully to carry out heat seals, cooling and cutting operation and can produce such as sealed width and reduce and the effect of higher operating speed, so that preferably make vertical filling-packaging machine can make this kind packaging bag.
Therefore, first target of the present invention is to provide a kind of vertical filling-packaging machine, its can: by not mobile cylindrical membrane heat seal, cooling and cutting cylinder film, form the transverse sealing part satisfactorily, and can: make to adopt polytype packaging bag of differently contoured shape.

Below, embodiments of the invention are described with reference to the accompanying drawings.
Fig. 5 is the view that shows the structure of vertical filling-packaging machine 1 according to an embodiment of the invention.
Vertical filling-packaging machine 1 comprises: vertical seal mechanism 6 is used for along the longitudinal direction heat seal and forms the match surface that guide forms the thin slice types of membranes 61 of drum by unshowned bag, with formation cylindrical membrane 60; Be used for transporting the film feed shelf 7 of cylindrical membrane 60 downwards; Be used for weighting material is imported the guiding nozzle 8 of cylindrical membrane 60; Liquid Antisplash machanism 20, it drives when guiding nozzle 8 is directed at weighting material; A pair of flat forms roller 25, and it is used for cylindrical membrane 60 is squeezed into even shape to form flat 60a; Transverse sealing and cutting mechanism 30, it is used for transverse sealing flat 60a and cuts the transverse sealing part to tear off packaging bag; Degasification mechanism 40, it is used for squeezing out the air that the cylindrical membrane 60 that has been directed at weighting material is held back; With bag holding plate 51, when being used for being driven in degasification mechanism 40, it keeps the bottom of cylindrical membrane 60.
Should be noted that: vertical seal mechanism 6 is representative vertical sealing mechanism and the film feed shelves that use in such vertical wrapping machine with film feed shelf 7, has therefore omitted relevant detailed description.
Guiding nozzle 8 is provided for liquid or pasty state weighting material is inducted into cylindrical membrane 60, and is set in the conveying channel of cylindrical membrane 60.The lower end of this guiding nozzle 8 is in the height place identical with liquid Antisplash machanism 20 basically.Adopt this mode, as will be described later, the lower end of guiding nozzle 8 can be by the liquid splashproof bar 21a of liquid Antisplash machanism 20, and 21b clamps.About this point, guiding nozzle 8 is configured to the cylindrical membrane 60 with cylinder transverse shape basically coaxial, so that weighting material can evenly be inducted into cylindrical membrane 60.
The guiding nozzle 8 of current embodiment guides weighting material off and on, and as shown in Figure 6, has valve arrangement in its lower end side.Control cock 8c vertically is arranged on the guiding blast tube 8a that is used for transmitting weighting material movingly.By the opening 8b of mobile control cock 8c with On/Off guiding blast tube 8a, the weighting material pilot operationp is controlled.
Fig. 7 is the lateral plan that shows the structure of liquid Antisplash machanism 20; Fig. 8 is the birds-eye view that shows the structure of identical liquid Antisplash machanism 20.
Shown in Fig. 7 and 8, liquid Antisplash machanism 20 has a pair of liquid splashproof bar 21a, 21b, and a pair of liquid splashproof bar 21a, the conveying channel that 21b crosses cylindrical membrane 60 is provided with relative to one another.
Liquid splashproof bar 21a, 21b cover 23a being formed with near its centre, 23b, and lid 23a, and 23b is smooth on both sides.Lid 23a, 23b are formed so that surround guiding nozzle 8 along the periphery that guides nozzle 8.More specifically, liquid splashproof bar 21a, 21b are formed the constant distance with the periphery that is determined to guiding nozzle 8 when it advances.
Each liquid splashproof bar 21a, 21b is connected to air cylinder 22a respectively, the leading section of the arm of 22b.Adopt this mode, by driving air cylinder 22a, 22b, liquid splashproof bar 21a, 21b be along the direction motion that is transported (horizontal direction shown in Figure 5) direction perpendicular to cylindrical membrane 60 wherein, to take by the position of solid line indication with by the position of long and short dash line indication.
When weighting material was directed into cylindrical membrane 60 from guiding nozzle 8, so the liquid Antisplash machanism 20 of structure used liquid splashproof bar 21a, the progressive position of 21b.As liquid splashproof bar 21a, when 21b advanced, cylindrical membrane 60 was sandwiched in liquid splashproof bar 21a, between the 21b and the guiding outer periphery of nozzle 8 and each liquid splashproof bar 21a, and between the 21b, thus sealed basically.In this case, owing in the opening 8b opening of the lower end of guiding nozzle 8 cylindrical membrane 60 in the sealing state basically, do not have interference to the weighting material pilot operationp.
As will be described later, being positioned at liquid splashproof bar 21a in the zone that will be heat sealed, during 21b when top, the vertical filling-packaging machine 1 weighting material pilot operationp of current embodiment is performed.Therefore, even weighting material splashes during pilot operationp, because cylindrical membrane 60 is clipped in therebetween by the liquid Antisplash machanism, so that it keeps sealing basically, weighting material will can not splash the zone that will be heat sealed.
In the conventional bag installation of not disposing this mechanism 20, when the easier quilt of guiding splash have low-viscosity weighting material the time, as an example, weighting material must be with lower guiding speed guiding.Yet because liquid Antisplash machanism 20 is provided, even weighting material is directed at high speed, this embodiment does not exist weighting material wherein to stick at the problem in the zone that will be heat sealed yet.Therefore, can carry out pilot operationp, cause being used to making the reducing of cycle of individual packaging bag with more speed.
Cross the conveying channel of cylindrical membrane 60 below the lower end of guiding nozzle 8, flat forms roller 25 and is provided with relative to one another.Flat forms roller 25 and constructs in the mode that is similar to the ironing roller that the typical case uses in such wrapping machine, cylindrical membrane 60 is clipped in therebetween rotates.Adopt this mode, cylindrical membrane 60 is extruded to form flat 60a.Therefore, the flat preferred length that forms roller 25 makes them can be at cylindrical membrane 60 whole width extrusion cylinder films 60.Flat forms roller 25 and is set up, so that they can be moved forward and backward along the vertical direction of the direction that is transported with cylindrical membrane 60 wherein by unshowned drive source.In addition, flat formation roller 25 is configured to be driven to rotate them by unshowned another kind of seemingly drive source.About this point, flat forms roller 25 and is actuated to synchronously rotate with film feed shelf 7.
So the flat of structure forms roller 25 and is used to separate the weighting material that is directed into cylindrical membrane 60, and is used for clamping cylindrical membrane 60 in the elevation-over of the weighting material that imports.
Be actuated to rotation when flat forms roller 25, wherein cylindrical membrane 60 is clipped in the middle of it, and cylindrical membrane 60 is transported downwards when forming flat 60a.Flat 60a be wherein cylindrical membrane in subsequent step by the zone of transverse sealing.As flat 60a during by this way by transverse sealing, the transverse sealing part has been difficult for pleat.
As shown in figure 10, transverse sealing and cutting mechanism 30 comprise: the heating pole 31 and the heating pole container 32 that are used for the transverse sealing operation; Be arranged on the level and smooth mechanism (smoothingmechanism) 70 of their belows; With a pair of a pair of cooling rod 34a that is used to cool off and cut the transverse sealing part, 34b.In addition, cutter 35 is set among the cooling rod 34a, is used for cutting cylinder film 60.
The conveying channel that heating pole 31 and heating pole container 32 cross cylindrical membrane 60 is provided with relative to one another, and is constructed to respectively along moving perpendicular to the direction of the direction of wherein transporting cylindrical membrane 60.Heating pole 31 and heating pole container 32 are referenced the drive source driving that Figure 12 will be described later, and cylindrical membrane 60 can be clipped in therebetween.
With reference to Figure 11 level and smooth mechanism 70 is described.Figure 11 is the figure of heating pole 31 and heating pole container 32 when watching from below.About this point,, omitted its detailed description because the structure of level and smooth mechanism 70 is similar to by disclosed structure among the JP-A-2002-234504 of the previous application of current applicant.
Level and smooth mechanism 70 comprises a pair of contact component 73a, 73b, and its contact is formed the cylindrical membrane 60 that roller 25 is squeezed into even shape by flat, to stretch film (referring to the arrow that draws) to both sides.Be adhered to each contact component 73a by the pad of making such as the elastomeric material of rubber 76, on the front surface of 73b, so that cylindrical membrane 60 can be stretched.Select for use the material of making pad 76 can not apply excessive friction force to cylindrical membrane 60, like this when the cylindrical membrane 60 that is clipped in the middle when the direction of arrow stretches, this can cause cylindrical membrane 60 to be expanded.
Because each contact component 73a, 73b connects with similar structure, will be described as representative instance with a contact component 73a below.One end of pitman 72 is rotatably supporting contact component 73a, and pivot shaft 75 is rotatably supporting the opposite end of pitman 72.Therefore, when pitman 72 rotated around pivot shaft 75, contact component 73a can pivot along the direction shown in the arrow and move.In addition, the extension coil spring 74 that is hooked on the snap hook 71 makes the other end be hooked on the front end place of pitman 72.In the initial condition of smooth structure 70, as shown, utilize the effect of extension coil spring 74 and block 77, contact component 73a is positioned as than other structure member more near cylindrical membrane 60.
When heating pole 31 and heating pole container 32 advance, so level and smooth mechanism 70 operations of structure.Particularly, when heating pole 31 and heating pole container 32 when cylindrical membrane 60 advances, at heating pole 31 with before heating pole container 32 contacts cylindrical membrane 60, contact component 73a respect to one another, 73b is clipped in the both end sides of cylindrical membrane 60 therebetween.When heating pole 31 in this state and heating pole container 32 were advanced further, contact component 73a, 73b be respectively to the movement outside of cylindrical membrane 60, simultaneously their friction cylindrical membranes 60.Therefore, cylindrical membrane 60 is held, and folding line is touched parts 73a simultaneously, and 73b removes.As a result, cylindrical membrane 60 is accepted pressure satisfactorily and is heated bar 31 and 32 heating of heating pole container.
As mentioned above, in heat seal operating period, the contact component 73a of level and smooth mechanism 70,73b is clipped in the middle cylindrical membrane 60 at (below heating pole 31) below the zone that will be heat sealed, the load that is applied to heat sealing part by weighting material uprises like this, up to the heat seal EO.Therefore, prevented because the weight heat sealing part expansion of weighting material.
As shown in figure 10, cooling rod 34a, 34b are set under the level and smooth mechanism 70, and utilize the drive source that will be described later with reference to Figure 12 to drive them, are clipped in therebetween with the transverse sealing part 65 with cylindrical membrane 60.In addition, because cooling rod 34a, 34b is sent to these parts with cooling transverse sealing part 65 with the heat of heat sealing part 65, and they are preferably made by the material with high thermal conductivity.
In the groove that forms in cooling rod 34a, a cooling rod 34a disposes cutter 35, is used to cut transverse sealing part 65 so that packaging bag 66 is separated from cylindrical membrane 60.Utilize unshowned drive source, cutter 35 is constructed movably to advance to cylindrical membrane 60 and to retreat from cylindrical membrane 60.Relative cooling rod 34b is formed with the groove that is used to hold the cutter 35 that is used for cutting operation when advancing.
About this point, heating pole 31 and heating pole container 32 and a pair of cooling rod 34a, 34b all are constructed to be different from contour shape heating pole and the heating pole container and the cooling rod exchange of their other type.In traditional transverse sealing and cutting mechanism 230 as shown in Figure 3, for example have difform packaging bag in order to make, whole mechanism must be by whole exchange.Yet because only heating pole 31 and cooling rod 34a, 34b need exchange with those dissimilar heating poles and cooling rod, and the transverse sealing of current embodiment and cutting mechanism 30 help swap operation.In addition, owing to need not to provide a plurality of whole mechanisms according to the shape of packaging bag, equipment cost can be suppressed.
At the lower end position place of Figure 10 A, heating pole 31 and heating pole container 32 are positioned in and packaging bag cutting position L1 equal height place.In this state, by driving heating pole 31 and the 32 execution heat heating of heating pole container.On the other hand, the upper end position place in Figure 10 B, the whole upward movement of transverse sealing and cutting mechanism 30 is to take the position with packaging bag cutting position L1 equal height.In this state, by driving cooling rod 34a, 34b and cut tool 35, transverse sealing part 65 is cooled off and is cut.About this point, " packaging bag cutting position L1 " indication cylindrical membrane 60 is by the position of cutter 35 cut-off parts, and along the direction that cylindrical membrane 60 wherein is transported, is set at the central authorities of transverse sealing part 65.
With reference to Figure 12, will describe the detailed construction of transverse sealing and cutting mechanism 30 and be used to move up and down the structure of the driver train 80 of transverse sealing and cutting mechanism 30.In order to simplify description, ignored level and smooth mechanism 70 in the demonstration of Figure 12.
The driver train 80 that is used to move up and down transverse sealing and cutting mechanism 30 comprises: the cover keep lever 81 that is used to keep transverse sealing and cutting mechanism 30; Be used to move up and down the ball screw 82 of cover keep lever 81; With as being used for the servomotor SM3 of the drive source of swing roller screw rod 82.
Cover keep lever 81 is whole to keep heating poles 31 and heating pole container 32, a pair of cooling rod 34a, 34b, is used to open and close their each toggle link 85,86 and servomotor SM1, SM2.Cover keep lever 81 can arrange that this guide member for example comprises two strut bar (not shown) that are set parallel to each other along guide member vertical shifting ground, and ball screw 82 is mediate.
So the driver train 80 of structure is used to put on servomotor SM3 from the predetermined electrical signals of unshowned controller, with the predetermined amount of rotating servo motor SM3, ball screw 82 is rotated relatedly with it.Adopt this mode, heating pole 31, heating pole container 32, cooling rod 34a, 34b etc. are moved up and down by integral body and are positioned the pre-position.Only, can change the distance of motion in this case by changing the electric signal that self-controller is applied to servomotor SM3.In addition, can accurately locate heating pole 31, heating pole container 32, cooling rod 34a, 34b etc. by ball screw 82 relatively with the driver train 80 that servomotor SM1 forms.
Move the structure of transverse sealing and cutting mechanism 30 and the conventional confguration as shown in Fig. 3 relatively the time with respect to stationary cylinder film 60 in will be as current embodiment, owing to use the transverse sealing and the cutting mechanism 30 of driver train 80 up-and-down movements, the structure of current embodiment is subjected to the problem that positional precision descends.Yet, as shown in figure 15, to compare with the conventional confguration that is used for mobile cylindrical membrane 60, the structure of current embodiment can realize the more location of high position precision.
Above-mentioned reason will be described below.In structure shown in Figure 15, the film feed roller 107 (referring to Fig. 1) that cylindrical membrane 60 provides by the film feed shelf 7 (referring to Fig. 1) that provides with the belt conveyer form, with the form of a pair of rotation roller usually etc. transports.In this case, the feed quantity of cylindrical membrane 60 changes easily.On the other hand, in the structure of the Fig. 2 that is used for mobile cylindrical membrane 60, after being heat sealed, cylindrical membrane 60 must be moved downward cooling rod 34a, the height of 34b once more.Adopt this mode, in the structure that is used for transporting the cylindrical membrane 60 that is inducted into weighting material intermittently, downwards, the weight of the weighting material of importing is applied to cylindrical membrane 60 as impulsive force, and so in some cases, cylindrical membrane 60 can slightly be expanded.This expansion can change the distance that cylindrical membrane 60 is transported.Especially, the transverse sealing part of not cooled off fully 65 is subjected to the influence of this expansion easily.
As a comparison, as in current embodiment, in the structure of transporting and be used for mobile transverse sealing and cutting mechanism 30 that is used for stopping cylindrical membrane 60, though itself cause mal-position by mobile transverse sealing and cutting mechanism 30, this mal-position helps to be used for the physical construction of the driver train 80 of upper and lower mobile transverse sealing and cutting mechanism 30, compare with the structure that is used for mobile cylindrical membrane 60 like this, the amount of mal-position is very little.In addition, in current embodiment, because cylindrical membrane 60 need not to be transported off and on, cylindrical membrane 60 extremely can not be because the weight expansion of weighting material.Particularly, the transverse sealing part 65 that is not cooled extremely can not expansion or distortion.
Next, about from being heat sealed to required time of cutting, will between the structure of current embodiment, conventional confguration shown in Figure 3 and the conventional confguration shown in Figure 15, compare.Compare between the structure to the structure of current embodiment and Fig. 3, the structure of current embodiment requires the longer time of cutting, promptly needs to move up and down the required time of transverse sealing and cutting mechanism 30 more; But compare with the structure of Fig. 15, this time has been reduced.This be because: for example, transporting in the cylindrical membrane 60, having difficulties as the structure that in the structure of Figure 15, is used for transporting cylindrical membrane 60 downwards with specific predetermined speed or more speed in order to reduce to be applied to the impulsive force of cylindrical membrane 60.
In order to increase the speed of packaging bag manufacturing operation, can implement following control.In Figure 10, cooling rod 34a, the distance between the 34b is identical with distance between heating pole 31 and the heating pole container 32, but cooling rod 34a, the distance between the 34b can be set to shorter.At the upper end position place of transverse sealing and cutting mechanism 30, heating pole 31 is positioned with heating pole container 32, and the height with flat formation roller 25 is identical highly basically.Therefore, need guarantee that the distance between heating pole 31 and the heating pole container 32 is longer than the distance that flat forms between the roller 25, interfere so that heating pole 31 and heating pole container 32 can not form roller 25 with flat.On the other hand, because cooling rod 34a, 34b can not interfere flat to form roller 25, can reduce cooling rod 34a, the distance between the 34b.This causes cooling rod 34a, the distance that the 34b motion is short, thus make and can drive them with more speed.About this point, only be applied to the electric signal of the servomotor SM2 shown in Figure 12 by change, cooling rod 34a, distance can be regulated between the 34b.
With reference to Figure 13 degasification mechanism 40 and bag holding plate 51 are described below.Should be noted that: Figure 13 has only shown that planar section forms roller 25, but shows transverse sealing and the cutting mechanism 30 that is arranged between flat formation roller 25 and the degasification mechanism 40.
The second degasification plate 42a, 42b are used for pushing the cylindrical membrane 60 that wherein has been inducted into weighting material from both sides, to discharge the parts of the air in the cylindrical membrane 60.Then, their size is formed the size corresponding to packaging bag 66, so that they can advantageously carry out its pressing operation.On the other hand, the first degasification plate 41a, 41b are the parts that are used to prevent that the weighting materials in the cylindrical membrane 60 are pushed upwardly between exhaust cycle, and are set at the second degasification plate 42a, the 42b top.
So operation of the degasification mechanism 40 of structure below will be described.
At first, make the first degasification plate 41a, 41b is closer proximity to each other, has the gap that width is enough to allow the air in the cylindrical membrane 60 upwards to overflow therebetween.Next, as the second degasification plate 42a, 42b pushes weighting material and is directed into wherein cylindrical membrane 60 when wherein their approximating directions are advanced from both sides; And be associated therewith, by the first degasification plate 41a, the zone of the cylindrical membrane 60 that 41b is clipped in the middle upwards squeezes out the air in the cylindrical membrane 60 from wherein, with from cylindrical membrane 60 air-outs.
About this point, the second degasification plate 42a, 42b preferably arranged so that: its move distance can be conditioned, so that in this degas operation, the air in the cylindrical membrane 60 can advantageously be squeezed out.Adopt this mode, according to the size of packaging bag 66 and the amount of weighting material, by compatibly regulating the second degasification plate 42a, the move distance of 42b, degas operation can be performed, so that the amount of air minimum in the cylindrical membrane 60.In addition, can make the first degasification plate 41a, 41b is so far forth closer proximity to each other, even so that therein in the scope that air can squeeze out reposefully, weighting material upwards extruding also has difficulties.Yet, shown in Figure 13 B,, weighting material exceeds the first degasification plate 41a even being extruded, 41b, and the transverse sealing operation will can not be subjected to negative influence, unless the height of weighting material reaches the regional A that will be heat sealed.
With reference to Figure 14 to 17, below will provide the as above description of the packaging bag manufacturing operation of the vertical filling-packaging machine 1 of the current embodiment of structure.
In the initial condition shown in Figure 14 A, make in the packaging bag manufacturing step in front; And the heat seal lower end of cylindrical membrane 60 is positioned at L1 place, packaging and cutting position.Then, liquid Antisplash machanism 20 is in the closed condition.Cylindrical membrane 60 is by liquid splashproof bar 21a, and 21b is clipped in the middle, and becomes even shape basically, and is in sealing state basically.Yet cylindrical membrane 60 is not exclusively smooth, but by guiding nozzle 8 and liquid splashproof bar 21a, the zone that 21b is clipped in the middle is along the peripheral projection of guiding nozzle 8.Flat forms roller 25, transverse sealing and cutting mechanism 30 and degasification mechanism 40 will be set in the open mode, and bag holding plate 51 is placed in the horizontality simultaneously.Transverse sealing and cutting mechanism 30 are positioned at the lower end of its action radius; And heating pole 31 and heating pole container 32 are positioned in and packaging bag cutting position L1 equal height place.Describe as the back, the regional A that will be heat sealed in the transverse sealing step is positioned at above the liquid Antisplash machanism 20.
Next, as shown in Figure 14B, from the guiding of guiding nozzle 8 beginning weighting materials, liquid Antisplash machanism 20 remains in the closed condition.Because cylindrical membrane 60 is clipped in the middle by liquid Antisplash machanism 20, this weighting material will can not adhere to the regional A that will be heat sealed.
Next, shown in Figure 14 C, pilot operationp continues, and arrives in the packaging bag 66 sealed single bag amount (referring to Figure 17) up to the weighting material that imports.Liquid Antisplash machanism 20 is switched to open mode in the centre of this pilot operationp.About this point, when liquid Antisplash machanism 20 was opened, pilot operationp just stopped once, or as-is condition continues.
Have the exterior intention of air exhaustion that makes in the cylindrical membrane 60, liquid Antisplash machanism 20 is opened in the centre of pilot operationp.As mentioned above, when liquid Antisplash machanism 20 was closed, cylindrical membrane 60 kept sealing basically.Therefore, be that a bag guides a certain amount of weighting material if attempt as-is condition, the air in the cylindrical membrane can not overflow, and the result is along with increasing weighting material is directed, and the pressure in the cylindrical membrane 60 becomes higher.When pressure was applied to cylindrical membrane 60 by this way, cylindrical membrane 60 can projection and distortion, or can break at the heat sealing part of the lower end of cylindrical membrane 60.And as the result that the cylindrical membrane internal pressure increases, the air under the high pressure can be from by preventing spray liquid bar 21a, and the minim gap that 21b narrows down is squeezed out.If air squeezes out from minim gap by this way, air is flow at high speed, if weighting material adheres near preventing spray liquid bar 21a like this, and the gap location between the 21b, air-flow can upwards blow afloat weighting material.
In addition, even liquid Antisplash machanism 20 is opened in the middle of aforesaid pilot operationp, owing to following reason, the possibility that weighting material will adhere to the regional A that will be heat sealed is quite low.When as in current embodiment, weighting material be directed into by liquid Antisplash machanism 20 clamp and the cylindrical membrane 60 of smooth basically sky in the time, the weighting material most probable begins the back in pilot operationp to be splash at once.Yet when weighting material was directed into wherein in the cylindrical membrane 60 that existing a certain amount of weighting material is directed into, weighting material can not splash too much.
About this point, shown in Figure 13 C, because the air cylinder 22a that the liquid Antisplash machanism 20 of current embodiment uses as drive source, 22b (referring to Fig. 8) is with moving liquid splashproof bar 21a, 21b, liquid splashproof bar 21a, 21b is opened away from each other fully, and they are in open mode like this.Yet, replacing air cylinder, drive source can be changed and be servomotor or analogue, and in this structure, servomotor can be used to regulate liquid splashproof bar 21a, the opening of determining between the 21b.In this case, liquid splashproof bar 21a, 21b does not open away from each other fully, but preferably closer to each other, and middle gap is enough to allow the air in the cylindrical membrane 60 to be overflowed.Adopt this mode,, thereby prevent that further weighting material from investing the regional A that will be heat sealed during the second half section of pilot operationp even cylindrical membrane 60 also can be extruded.
Next, shown in Figure 15 D, film feed shelf 7 (referring to Fig. 5) is actuated to transport cylindrical membrane 60 downwards.Thisly transport operation and be performed, drop to flat up to the weighting material height that imports and form roller below 25.
Next, shown in Figure 15 E, cylindrical membrane 60 is formed roller 25 by flat and clamps, and transporting of cylindrical membrane 60 stops simultaneously.In this case, forming by flat under the zone that roller 25 clamps, holding back the air of scheduled volume in the cylindrical membrane 60.
Next, shown in Figure 15 F, flat forms roller 25 and is actuated to rotation, thereby transports cylindrical membrane 60 downwards, forms flat 60a simultaneously.In this case, be noted that film feed shelf 7 also is driven simultaneously.Thisly transport operation and be performed up to the bottom of cylindrical membrane 60 and be maintained on bag holding plate 51, and the regional A that will be heat sealed is heated bar 31 and heating pole container 32 is clipped in the middle.
Next, shown in Figure 16 G, degasification mechanism 40 is actuated to push the air that is trapped in the cylindrical membrane 60, and the bottom of cylindrical membrane 60 is maintained on bag holding plate simultaneously.
At first, the first degasification plate 41a, 41b is closer proximity to each other so that the top of cylindrical membrane 60 narrows to the degree that air can overflow.In addition, clamped the flat formation roller 25 of cylindrical membrane 60 along wherein their directions separated from one another are mobile slightly.Adopt this mode, flow passage guarantees that air extrusion goes out.
Then, make the second degasification plate 42a, 42b advances to push cylindrical membrane 60 from both sides.Then, the air that is trapped in the cylindrical membrane 60 is exceeded by the first degasification plate 41a, the zone that 41b is clipped in the middle by extruding upwards.In this case, by making the first degasification plate 41a, the 41b degree that can be discharged from hardly closer proximity to each other to weighting material, and by compatibly regulating the second degasification plate 42a, the amount of movement of 42b, weighting material are prevented from rising to the regional A with being heat sealed.
About this point, the first degasification plate 41a, the 41b and the second degasification plate 42a, 42b can be driven with the multiple different timing that differs from one another.For example, at the second degasification plate 42a, after 42b is at first closer to each other, the first degasification plate 41a, 41b can be controlled to closer to each other.In this case, owing to make the second degasification plate 42a, 42b is closer proximity to each other, and the height of weighting material rises.Then, make the first degasification plate 41a, 41b is closer proximity to each other, thereby further squeezes out the air in the cylindrical membrane 60.
Alternatively, can be basically and make the first and second degasification plates closer proximity to each other simultaneously.When the control first degasification plate and the second degasification plate with basically and when simultaneously closer to each other owing to make the second degasification plate 42a, the impact that excessively high speed caused when 42b was closer proximity to each other, some weighting materials can upwards splash.Similarly, the driven timing of degasification plate preferably compatibly is provided with according to the characteristic of weighting material etc.Preferably, in order to pack the weighting material that splashes easily, at first make the first degasification plate 41a, 41b is closer proximity to each other.Alternatively, the first degasification plate 41a, 41b can structurally be designed to than the second degasification plate 42a, and 42b is earlier closer to each other, so that make the first degasification plate and the second degasification plate basically with simultaneously closer proximity to each other.
Next, shown in Figure 16 H, cylindrical membrane 60 is clipped in the middle by the heating pole 31 of transverse sealing and cutting mechanism 30 and heating pole container 32, cylindrical membrane 60 is exerted pressure and heat cylindrical membrane 60.This causes forming the transverse sealing part 65 in the cylindrical membrane 60.In this transverse sealing operation, owing to be arranged on the effect of the level and smooth mechanism 70 (referring to Figure 11) of heating pole 31 and heating pole container 32 belows, the regional A of the cylindrical membrane 60 that is heat sealed is not had folding line ground and is kept, thereby advantageously realizes heat seal.
Next, shown in Figure 16 I, after heating pole 31 and heating pole container 32 have retreated, the time durations when transporting of cylindrical membrane 60 stops, transverse sealing and cutting mechanism 30 are risen fully, arrive the height of packaging bag cutting position L1 up to cutter 35.Because driver train 80 is carried out this upward movement operation, whole transverse sealing is positioned with relative high positional precision with cutting mechanism 30.
Next, shown in Figure 17 J, the transverse sealing part 65 bar 34a that is cooled, 34b clamps, so that it turns cold.In addition, the cutter 35 that is arranged among the cooling rod 34a advances with the packaging bag 66 of cutting or tear from cylindrical membrane 60.
Consider the material of cylindrical membrane 60, the size of transverse sealing part 65 etc., the time of the cutting operation of cutter 35 preferably compatibly is set.For example, when the cooling of transverse sealing part 65 need not when long-time, cutter 35 can be at cooling rod 34a, and the time durations when 34b is closed is driven simultaneously.On the other hand, when transverse sealing part 65 needed cooling for a long time, cutter 35 can be driven after the schedule time when 34b is closed at cooling rod 34a.
Next, shown in Figure 17 K, cooling rod 34a, 34b retreat with the release bar 34a that is cooled, and the packaging bag 66 that 34b keeps causes packaging bag 66 to drop on bag holding plate 51.Then, make bag holding plate 51 enter heeling condition, thereby cause packaging bag 66 to fall.
Next, shown in Figure 17 L, each parts of transverse sealing and cutting mechanism 30 representatives are returned to its position in the initial condition shown in Figure 14 A.Particularly, transverse sealing and the cutting mechanism 30 that is positioned at upper end position turns back to lower end position; Keep each other near and flat with the slight clearance that is used for degas operation form roller 25 and be opened; Bag holding plate 51 is returned to horizontality; And liquid Antisplash machanism 20 turns back to closed condition.
By repeating a series of abovementioned steps, sequential system is produced the wherein packaging bag 66 of sealing filler.
As mentioned above, by using the driver train 80 shown in Figure 12, vertical filling-packaging machine 1 according to current embodiment can move down heating pole 31 and the heating pole container 32 that action is provided with for sealing mechanism on the whole along the direction of transporting cylindrical membrane 60, with a pair of cooling-part 34a that is provided as cutting mechanism, 34b.Therefore, can carry out heat seal, cooling and cutting operation fully in not mobile cylindrical membrane 60 ground.Therefore, cylindrical membrane 60 need not to present downwards off and on, causes the possibility of less cylindrical membrane 60 with expansion, and if cylindrical membrane 60 is transported off and on because the expansion of cylindrical membrane 60 can appear in impulsive force; And the possibility that causes the less transverse sealing part 65 that is not cooled to expand or to be out of shape.In addition, because sealing mechanism and cutting mechanism are provided with independently of one another individually, according to the specification of packaging bag 66, heating pole 31 and heating pole container 32 and cooling rod 34a, 34b can with have difform heating pole and heating pole container and cooling rod and exchange.In addition, because driver train 80 is configured to whole mobile heating pole 31 and heating pole container 32 and cooling rod 34a, 34b compares with their structures of moving independently wherein, and structure and operation control are simplified.
In addition, as mentioned above, the vertical filling-packaging machine 1 of current embodiment is inducted into weighting material the cylindrical membrane 60 that is clamped by liquid Antisplash machanism 20 from guiding nozzle 8, and the regional A that is heat sealed is positioned at liquid Antisplash machanism 20 tops.Therefore, when weighting material is directed, weighting material will can not invest the regional A that will be heat sealed.And, because liquid Antisplash machanism 20 stays open, being inducted into cylindrical membrane 60 fully up to one bag weighting material amount, cylindrical membrane 60 or sealed lower portion edge will be not can not be out of shape or rupture owing to the importing of weighting material.
In addition, a pair of flat forms roller 25 and is actuated to clamp cylindrical membrane 60 in the elevation-over of the weighting material that imports, and the weighting material of importing will can not contact the regional A that will be heat sealed in the step of back.Adopt this mode, the regional A that is heat sealed is squeezed into even shape, and in this state, be transported to heating pole 31 and heating pole container 32, do not have weighting material and adhere to or be in contact with it with heat seal.Therefore, heat sealing part 65 is formed well, and can not have the defective sealing.In addition, formerly be squeezed into even shape, prevented that heat sealing part 65/ transverse sealing part 65 has folding line owing to be heated bar 31 and 32 pressurizations of heating pole container and area heated.In addition, in current embodiment,, can form heat sealing part 65/ transverse sealing part 65 more satisfactorily because level and smooth mechanism 70 is provided for the folding line of eliminating among near the regional A that will be heat sealed heating pole 31 and the heating pole container 32.
As mentioned above, be actuated to when the elevation-over of the weighting material that imports clamps cylindrical membrane 60 when a pair of flat forms roller 25, shown in Figure 14 E, air is trapped within the cylindrical membrane 60.Yet current embodiment uses degasification mechanism 40 with air-out, thereby makes the amount of air minimum in the packaging bag 66 that is included in manufacturing.
Be noted that in current embodiment as shown in figure 15, form roller 25 (but being not limited to this) by using a pair of flat, cylindrical membrane 60 is clamped at the weighting material elevation-over, weighting material can form roller 25 separately by a pair of flat.
In fact, according to the type of the material and the sealing filler of cylindrical membrane 60, the step of this formation flat 60a is optional.Even in this case, for regional A is carried out heat seal, by regional A being transported to heating pole 31 and heating pole container 32, transverse sealing part 65 can form satisfactorily, do not stay wherein and do not have weighting material, wherein regional A will be heat sealed, and pass through the effect of liquid Antisplash machanism 20, prevent that weighting material from adhering on the regional A.
