Conventional art

Plastic bag (Polythene Bag) is made by extremely thin plasticity (material) film, owing to behind the overlapping bunchy, adhere to mutually by static, is difficult for taking out singly.As taking out plastic bag, for the necessary opening of the article of packing into, this work bothers very much.If in occasions such as large-scale food processing factories, be provided with and spread over from film being become the sack shape to the large-scale equipment of filling a certain amount of article and sealing place, but consider from scrappy producer aspect, the machinery easily of so not working, all need rely on handwork, present situation is that less efficiently is realized packed operation.

To approach and tension-free sack or sheet material when automatically taking out one by one, generally adopt in many places sack or sheet material by the air-breathing method that is adsorbed on suction inlet by machinery.Suction inlet mostly is the pad that the rubber of round bowl-type is made, but at absorption sack or sheet material and when carrying, sack or sheet material can be fluttered in the breeze, on the way, sack can take place or sheet material peels off and sack or sheet material on can corrugate, be difficult to shorten the cycle time of taking out, machinery will stop continually simultaneously.Particularly, correctly take out plastic bag singly and make its very difficult technically realization of opening stably.

Disclosing of summary of the invention

The present invention is in view of the above-mentioned fact, its purpose be to provide a kind of can be efficiently and stably take out the sack withdrawing device of a sack and provide effectively a kind of and stably carry out the taking-up of sack or sheet material (シ one ト) and various form under suction inlet structure in the absorption unloading device that can use widely, sack or sheet material.

To achieve these goals, being characterized as of sack withdrawing device of the present invention has the storage bag device of taking in a plurality of overlapping sacks and the cylinder that is provided with the suction inlet of suction air around, the cylinder revolution is also taken out one by one by the sack in the suction inlet absorption storage bag device.The position relation of cylinder and storage bag device does not limit, and can take out the sack of storage bag device the top, can take out the sack of below of storage bag device yet.In addition, storage bag device can also can be to take under oblique or vertical state with sack to take under the horizontal positioned state.This device is owing to be to take out sack by the revolution of cylinder, thereby can be continuously and take out sack effectively.

Being characterized as of the sack withdrawing device of another program of the present invention, has the storage bag device of taking in a plurality of overlapping sacks, be provided with the cylinder of the suction inlet of suction air around, and wind pushing mechanism, the cylinder revolution, by the sack in the suction inlet absorption storage bag device and take out one by one, blow the wind of wind pushing mechanism to the peristome of the sack that takes out, so that this sack opening.Adopt this device, because the sack opening that takes out, can further carry out effectively pack into packed operation in the sack of article.In addition, adsorbed by suction inlet in the basic part near edge on every side of sack, particularly when the device of the sack opening that makes taking-up, the edge portion of the open side of sack is adsorbed by suction inlet.And cylinder is in the edge portion pull-out direction revolution of the sack that will adsorb from the sack of its absorption.

In order stably to take out sack and opening, wish adsorbing sack tightly until its front end by the suction inlet of cylinder, wherein, the edge portion of the open side of sack does not bend and does not form wrinkle.In order to realize above-mentioned requirements, being characterized as of another program of the present invention at the suction inlet place of cylinder, is provided with the auxiliary suction portion of main suction section and the opening side edge part that adsorbs the sack that exceeds main suction section.At this, main suction section is for can full intensity adsorbing sack when storage bag device takes out sack.Adopt the words of structure like this, even the opening side edge part of the sack that is adsorbing exceeds main suction section, auxiliary suction portion also can be from this part of back absorption, thus, the opening side edge part of sack can not bend and corrugate, can adsorb firmly by suction inlet, can from storage bag device, take out sack and make the sack opening really.For the opening side edge part that makes the sack that exceeds main suction section must be accommodated in the scope of auxiliary suction portion, preferably, sufficient length is extended by auxiliary suction portion in the front side at the cylinder gyratory directions of main suction section.

The aspirating mechanism (negative pressure generating mechanism) that makes main suction section and auxiliary suction portion produce suction can divide separately and is arranged.At this moment, in the case of necessary, the time of suction Controlled (opportunity), the suction of auxiliary suction portion is produced behind main suction section absorption sack.For fear of so loaded down with trivial details work, but also aspirating mechanism of dual-purpose.In another program of the present invention, be weaker than the suction of main suction section as suction with auxiliary suction portion, can roughly realize its purpose.For keeping the main suction section mechanism different without limits with the suction of auxiliary suction portion, for example, can be with the varying in size of the suction socket of the suction air of main suction section and auxiliary suction portion, perhaps paste net or fabric is adjusted suction in the inboard of suction socket.

Be that in another program of the present invention, auxiliary suction portion can form the air flue that is communicated with main suction section better.Be specially, form a plurality of grooves that are communicated with main suction section around cylinder, it can be used as auxiliary suction portion.So form, desirable state is, in the moment before main suction section absorption sack, auxiliary suction portion produces suction hardly, and from the moment that main suction section is plugged because of the absorption sack, auxiliary suction portion produces suction.

The principle of sack withdrawing device of the present invention is described with reference to Figure 1A～1C now.Shown in Figure 1A, cylinder 5 turns round in the direction of pulling out sack 1 in order contact with the open side of sack 1 in the storage bag device 2.Cylinder 5 is provided with the suction inlet 4 of suction air, and suction inlet 4 is made of with the auxiliary suction portion 8 that is arranged on the gyratory directions front side of main suction section 7 main suction section 7.At the suction inlet 4 of cylinder 5 by when above the sack 1, the weak auxiliary suction portion of suction does not adsorb under the state of sack and passes through, and main suction section 7 is being adsorbed than the opening lateral margin of the sack 1 downward part of bottom side slightly, shown in Figure 1B, pulls out a sack 1 from storage bag device 2.At this moment, the opening side edge part of sack 1 is not adsorbed by suction inlet 4, afterwards, during cylinder 5 revolution, because the suction of auxiliary suction portion 8, adsorb in proper order from the edge of absorbed portion, sack 1 can not corrugate, just first film by suction inlet 4 with firmly slack-free state absorption.Under this state, by the open side air-supply of wind pushing mechanism 6 from sack, shown in Fig. 1 C, sack 1 is opening reliably.

In order to make sack opening more reliably, in another program of the present invention, be to be provided with raised line at the suction inlet place.So, form longitudinal wrinkles, can between 2 films of sack, produce the gap at opening side edge part by the sack of suction inlet absorption, thus easier opening.Raised line for can form in the part that is adsorbed of sack longitudinal wrinkles just can, concrete form is qualification not, but preferably along the shape of the circumferencial direction of cylinder, is provided with a plurality of getting final product at certain intervals.In addition, when between raised line and cylinder surface, forming the bight, the sack in the suction first film and cylinder surface and raised line between also form the gap, the effect of auxiliary suction portion is played in this gap.Raised line can be arranged to one with cylinder, and perhaps split is fixed on the cylinder by little pin or adhesion zone, but preferably, rubber wheel is embedded cylinder around form so easy loading and unloading or carry out the adjustment of position, and,, take out sack easily by the friction of increase with sack.

As preventing to reduce the error that cylinder produces takes out sack from storage bag device, perhaps prevent the mechanism that the sack by cylinder absorption arbitrarily peels off because of the air-supply of wind pushing mechanism, consider around suction inlet, to be provided with the adhesion parts, to strengthen the suction of suction inlet.In addition, also in another program of the present invention, form corner part on suction inlet and the corresponding position of the side edge part absorption sack, like this, the side edge part of sack is adsorbed on corner part firmly, and air can be from transverse leakage, and sack is difficult to peel off from suction inlet.In addition, have the effect that forms with the same auxiliary suction portion of raised line at corner part, and have the effect that between 2 films of sack, forms the gap.

In another program of the present invention, it is characterized in that the side edge part with the sack that will take out contacts and push the bag maintaining body that is keeping with cylinder.Adopt this invention,, can prevent that also sack breaks away from the phenomenon of cylinder under its weight even in sack, drop into heavy slightly article.

In order more stably from storage bag device, to take out a sack, in another program of the present invention, it is characterized in that having the pressing device that the sack in the storage bag device is pressed from its one side thruster.As pushing side, can along the local pushing of the Width of sack, be to push the front side (open side) of the end sealing of sack better by the broad face pushing of sack.Thrust pressure preferably can be utilized counterweight or spring, actuator to wait and regulate.Adopt the words of pressing device like this, only pull out by cylinder directly traction, wanted first sack of taking out originally, stopped because its end sealing is suspended on the pressing device by the sack below the 2nd that pulls out by first sack with the friction of first sack, thereby can be prevented the phenomenon that a plurality of sacks are pulled out simultaneously reliably from storage bag device.

In other embodiments of the invention, it is characterized in that the thrust pressure intensity of pressing device is undertaken according to taking out object to obtain the processing of each optimal thrust pressure intensity by system controlled by computer.Because of the material of sack or overlapping number difference, exist the situation that under the thrust pressure of predefined regulation, can not correctly take out a sack, but as for the present invention, when operation, obtain the processing of each optimal thrust pressure, can further improve the reliability that takes out a sack.

Cylinder can turn round by hand by carrying out packed operator, but in order to improve operating efficiency, is preferably driven by motor (motor), at this moment, is provided with the switch that makes cylinder begin rotating switch and the revolution of cylinder is automatically stopped.In addition, the structure of cylinder is as being, when sack takes out failure, do not stop revolution and goes around, then can further improve operating efficiency.Can detect the suction inlet absorbent packet period of the day from 11 p.m. to 1 a.m and not have the different of absorbent packet period of the day from 11 p.m. to 1 a.m swabbing pressure by pressure sensor, perhaps can detect sack self and have or not and implement by optical sensor etc.

More than, sack withdrawing device of the present invention is illustrated, but, can be not limited to the occasion that the sack unloading device is a cylinder, and the sack that also can be used for taking out is the occasion of the sheet of symmetry for as the wherein relevant invention of suction inlet structure of pith.Another program of the present invention is the invention of the suction inlet structure in the absorption unloading device of a kind of sack or sheet material, it is characterized in that, auxiliary suction portion with edge portion of the main suction section of an edge portion of absorption sack or sheet material and sack that absorption exceeds main suction section or sheet material.The structure of this suction inlet for example is, is provided with this suction inlet on the one side of the unloading device that becomes the case shape, by with mobile unloading devices such as mechanical arm or cylinders, can be used for taking out one by one the occasion of sack or sheet material.Adopt the words of this suction inlet structure, one edge portion of sack or sheet material can not bend or corrugate, can be adsorbed to its front end firmly, thus whereabouts of sack or sheet material etc. in preventing to transfer, the work behind also can stably carry out in the sack of opening, packing into article or any stickup sheet material.Auxiliary suction portion is preferably and forms the air flue that is communicated with main suction section in another program of the present invention.

In addition, being configured in another program of the present invention of this suction inlet is having the occasion that spreads all over the raised line that main suction section and auxiliary suction portion mode extend, when absorption sack or sheet material, can separate sack or sheet material more reliably singly, and the opening of sack carries out easily also.

In addition, in another program of the present invention, adopt the suction inlet structure that has corner part with the side edge part corresponding section of sack that adsorbs or sheet material, the phenomenon that sack or sheet material peel off from suction inlet in can preventing to transfer.

When cylinder 5 adsorbs the plastic bag 1 that stores up in the bag devices, preferably begin not adsorption plastic bag 1 of auxiliary suction portion 8.Auxiliary suction portion 8 almost can realize this state, but for perfectly safe, can consider method as shown in figure 11 that as being above-mentioned structure promptly cylinder 5 is non-positive cylindrical shape, is provided with the nearer part of distance center on perisporium, and at this auxiliary suction portion 8 is set.Cylinder 5 is set to ellipse, main suction section 7 is set in distance center part far away, and in that near the part at center auxiliary suction portion 8 to be set gradually effectively same.Figure 12 A, Figure 12 B are that auxiliary suction portion 8 becomes movable embodiment.This embodiment is, the panel 46 that constitutes auxiliary suction portion 8 is connected with the cylinder body by hinge or the such link 47 of rubber, by will be from panel 46 to the outstanding rod member 48 in the side of cylinder along the guide member 49 that is arranged on the cylinder side, can be at the lower position that takes out plastic bag 1, panel 46 is bent to the inside, and in the top position that makes plastic bag 1 opening, panel 46 returns to the cylinder body and flushes.

On the top of body housing 10 protective cover 52 is housed, is provided with air guiding wall 57,, from its place ahead along cylinder 5, send the wind of wind pushing mechanism 6 to, make plastic bag 1 opening that is adsorbed on the cylinder 5 around cylinder, to form air flue in the inside of body housing 10.Also consider by protective cover 52 and air guiding wall 57, will be delivered to the downside of cylinder 5 from the wind of wind pushing mechanism 6, make the front end emersion of the plastic bag 1 in the storage bag device 2, plastic bag 1 is easily by cylinder 5 absorption.Protective cover 52 is provided with and makes the rotating switch S 1 of cylinder 5 beginnings.When the hand push by the operator compresses switch the rod member 41a of S1, motor 9 energisings.Wind pushing mechanism 6 is then better as sending hot blast.

Control with reference to Fig. 2 for the revolution of cylinder 5, Fig. 3, Figure 16 A, Figure 16 B illustrates in greater detail.Being arranged on the switch S 2 of cylinder 5 sides and the switch S 1 that is arranged on the protective cover 52 is arranged in parallel on motor 9.Usually, knock the position of block 40 and plastic bag 1 opening at the rod member 41b of switch S 2, cylinder 5 stops revolution.The operator packs article in the plastic bag 1 that is adsorbing into and when plastic bag 1 is pulled away from cylinder 5, the rod member 41a of palm button S1.So, shown in Figure 16 A, when switch S 1 was connected (ON), cylinder 5 began revolution.Cylinder 5 is in case revolution, and shown in Figure 16 B, the rod member 41b of switch S 2 just breaks away from block 40, because switch S 2 is in the ON state, also can continue revolution by original state even switch S 1 becomes the OFF state, with by suction inlet 4 adsorption plastic bags 1.During adsorption plastic bag 1,, inhale pad 37 and be adsorbed onto on the cylinder side plate 35a, the revolution brake activation power of cylinder 5 because the negative pressure in the cylinder 5 increases (air pressure step-down).Cylinder 5 continues revolution by original state, and by block 40, when switch S 2 becomes the OFF state, inhales pad 37 and also play brake action, makes cylinder 5 stalls.When not having adsorption plastic bag 1 on suction inlet 4, act on hardly owing to inhale the braking force of pad 37 generations, by block 40, switch S 2 also becomes the OFF state, because of the inertia of cylinder 5, and can be until stopping, shown in Figure 16 C, by block 40.Like this, cylinder 5 just is parked in the position of regulation when adsorption plastic bag 1, when not adsorbing, continues revolution up to absorption.In addition, when switch S 1 was not connected (ON) certain hour, motor 9, attraction mechanism 3 and wind pushing mechanism 6 were controlled as and stop.

The variation of the air pressure in the cylinder 5 is detected by the pressure switch (not shown), and its signal also can be used for the revolution of index drum 5.Pressure switch for example is installed to inhales on the pad 37, be not adsorbed onto under the less state of negative pressure on the cylinder 5 at plastic bag 1, and to motor 9 output ON signals, and when the negative pressure of adsorption plastic bag 1 becomes big, to motor output OFF signal.When pressure switch was in OFF and switch S 2 and becomes OFF, motor 9 stopped revolution.Be in ON in pressure switch, and switch S 2 is when being in the OFF state, just cylinder 5 does not extract plastic bag 1 and when stop position, motor 9 does not stop revolution.In addition, be under the state that stops at motor 9, when pressure switch switched to ON from OFF, promptly the operator when being adsorbed onto plastic bag 1 on the cylinder 5 under the open state and being pulled away from cylinder, made motor 9 begin revolution with hand.That is to say that even operator's inoperation switch S 1 is pulled away from cylinder 5 by plastic bag 1, cylinder 5 naturally and understandably begins revolution.But, even under these circumstances,, can wait for the operation of switch S 1 for safety etc., make cylinder begin revolution again.In addition,, can dispose fault or set a plurality of operational modes, also can carry out higher operation by signal with processing pressure switches such as microcomputer, switch S 1 and switch S 2.

The revolution control of cylinder is not limited to aforesaid way.For example, substitute and to detect the mode that has or not adsorption plastic bag 1 with pressure switch, the available various sensor of utilizing light or super sonic etc. go out to be adsorbed onto the plastic bag self on the cylinder, also can carry out the revolution control of cylinder.Much less, also can be irrelevant with the whether absorption of plastic bag, cylinder is whenever goed around and must be stopped.

Below, the improved embodiment of bag of the present invention withdrawing device is described.Figure 23 and Figure 24 illustrate another embodiment around the storage bag device, on the pedestal 59 that slides before and after the jack 15 of substrate 11 knee-actions of placing plastic bag 1 being arranged on can guide by guide rail 58, and by pulling out pedestal 59 forward, supply plastic bag easily.End plate 12 and be fixed on the pedestal 59, substrate 11 always keeps certain with the distance of ending plate 12.Prevent that 1 one-tenth 2 of plastic bags from ending part 17 from being arranged on the pillar 60 in cylinder 5 the place aheads from the 2nd of storage bag device turnover overlappingly, become arciform extension along periphery, be fixed on the fairlead 53 of expanded cellular rubber 61 crimping the ending plate of front end at the downside of cylinder.The 2nd ends part 17 as shown in figure 24, can be arranged to consistently press against with the size of plastic bag 1 two ends of plastic bag to horizontal slip.Keep fan 62 in the cover piece 13, so that the 1st plastic bag 1 emersion and being adsorbed on the cover piece 13.As adopt this cover piece 13, the effect that also can dispose because of pressing device 14 makes one of plastic bag take out for example damaged easily paper bag of difficulty or the bag of rub big bag, sealing of the no end etc.

In addition, install except that electrical equipment 63, from removing electric air, to remove the static of plastic bag except that the plastic bag 1 of electrical equipment 63 in storage bag device blows in the side of body housing 10.Be provided with to remove electrical equipment 63 the place so long as can to plastic bag 1 blow remove electric air just blow can, also can be arranged on cover piece 13 or the wind pushing mechanism 6.It is not necessary removing electrical equipment 63.In addition, owing to also store static on the cylinder 5, so, can around cylinder 5, be provided with and remove brush (not shown) and contact with it.

In this device, as shown in figure 25, plate 12 moves the side inwards by only making, also can be with the taking-up singly and the opening of hand-held plastic bag 74.At this moment, plastic bag 74 with handles is adsorbed by the main suction section 7 of cylinder by the part shown in the symbol among the figure 75.The 2nd ends the outside that part 17 moves to plastic bag.In addition, in this embodiment, use not common cover piece 13 and Figure 17 A, the pressing device 14 shown in Figure 17 B with fan.

Figure 39 illustrates another embodiment of storage bag device portion, at this, is provided with to

upper bottom portion

104a, 104b at the front and rear of the substrate 11 of placing plastic bag.So, can relax, owing to can form the gap to each other, can alleviate the friction of pulling out when the plastic bag, can realize the taking-up one by one of plastic bag well at plastic bag up and down in the central authorities of plastic bag.

Figure 31 A, Figure 31 B illustrate the improvement example of cover piece.At first, in the example of Figure 31 A, be provided with anti-escape of air parts 96 in the inside one side near the edge part of cylinder 5 of cover piece 13, plastic bag 1 is easily by suction inlet 4 absorption.Should anti-escape of air parts 96 preferably form by soft rubber etc.Figure 31 B is the example that also is provided with anti-escape of air parts 96 on cover piece 13, but the anti-escape of air parts 96 of this moment are tabular, but is pivotally mounted to the inside side of cover piece by easy on and off such as hinges.So, even the number of plastic bag 1 reduces, and when having the gap between plastic bag and cylinder, thereupon, the revolution by tabular anti-escape of air parts 96 can prevent escape of air usually.Should can only depend on deadweight to be overlapped on the plastic bag 1 by anti-escape of air parts 96, but also can under spring force, push plastic bag 1.

Figure 17 A, Figure 17 B and Figure 18 illustrate another embodiment of pressing device 14.In the present embodiment, between the sidewall of body housing 10, set up pillar 76, on pillar, fixing the slide plate 77 of linear guides by the part of angle bar shape, on the bottom of the track 78 of the linear guides that slides up and down, propping up tabular push-pads 79 by bolt or the bearing earth's axis that can freely swing, in the upper end of track 78 counterweight 23 is being set, simultaneously, spring 80 is connected to the track upper end from pillar 76, and the marginal portion of the bottom of push-pads 79 is from last vertical pushing plastic bag 1.The two sides, bottom of push-pads 79 becomes chamfering, and the marginal portion of front end is somewhat the R shape.Even adopt such pressing device, also can stop 1 one-tenth of plastic bag to overlap ground more than 2 reliably and from storage bag device, take out.In addition, preferably shown in Figure 17 B, pressing device 14 is arranged side by side in front and back, 2 push-pads 79 are knee-action respectively separately, and can adjust the form of thrust respectively.So, by pressing device 14 is arranged to 2, can further improve the reliability that takes out a sack.

Figure 40～Figure 42 illustrates the A to Figure 17, the further improved embodiment of the pressing device shown in Figure 17 B.But this pressing device 14 has 2 tabular push-pads 117,118 of knee-action independently.But push-pads 117 is being propped up by the bolster 121 of the easy on and off action earth's axis that can freely swing by linear guides 132, but and push-pads 118 is being propped up by the bolster 134 of the easy on and off action earth's axis that can freely swing by linear guides 133.Spring 120 from be installed to fixing carriage 119 on the pillar 76 be suspended to pushing plastic bag 1 by on the push-pads 117 of edge side, and spring 122 is suspended on the push-pads 118 of push-pads 117 front sides from the bolster 121 of the push-pads of rear side.For this reason, on the push-pads 117 of bag edge side, produce the thrust pressure with the proportional intensity of amount of movement that makes progress, but on the push-pads 118 of its front side, produce and highly irrelevant roughly certain thrust pressure.When two push-pads 117,118 did not push plastic bag 1, the push-pads 118 of front side was downward, and the pushing sensor (limit switch) 123 that detects the pushing state is housed on the push-pads of front side.This switch 123 as shown in figure 41, the lower end of push-pads 118 in than push-pads 117 slightly down when becoming the state of pushing bag 1, the bar of switch 123 is by bolster 121 pushings, switch connection.In addition, the push-pads 117 of bag edge side is hung by steel rope 124 and is held, and steel rope passes pillar 76 and is suspended on the pulley 125 as shown in figure 42, and its front end is connected with bolt 127 by spring 126.Bolt 127 is screwed into by in the stepping motor 128 rotating hex screws 129, as motor 128 is rotated so that bolt 127 passes in and out, and can add and subtract the thrust pressure of push-pads 117,118.

Below to by above-mentioned pressing device 14, the whole control flow with the device that takes out a sack in the time of the plus-minus thrust pressure describes.At first, by Figure 43 the configuration of sensor main in this sack withdrawing device or motor etc. is described.Among the figure 115 is the sack height sensor, by detecting the action of the tabular anti-escape of air parts of swinging 96, can find whether empty opening stipulated above gap between sack 1 and the cylinder 5.Among the figure 116 is jack location confirmation sensor.Jack 15 is owing to consider to pull out forward from replenishing sack 1 easily, but when operation, can confirm whether jack is on the correct position.And 130 among the figure is the pressure sensor that detects the pressure variation in the cylinder, and 131 are the jack motor.In addition, be marked by identical symbol, and omit its explanation for the member that so far illustrates.

The control of this device is by the main microcomputer of the control of the revolution of carrying out cylinder 5 and suction

wind pushing mechanism

3,6, make jack about in the of 15 the jack with the height of regulating sack 1 use these three microcomputers of microcomputer of the thrust pressure adjusting usefulness of microcomputer and pressing device 14 to carry out.Figure 44 is the diagram of circuit that the control content of being undertaken by main microcomputer is shown, and Figure 45 is the diagram of circuit of jack with microcomputer, and Figure 46 regulates the diagram of circuit of using microcomputer for thrust pressure.In this device, can select just when sack takes out successfully, cylinder stops, in a single day breaking away from cylinder at the sack that takes out just makes cylinder automatically begin rotating " automatic mode ", even sack break away from the cylinder operator also not according to pressure roller begin to turn round switch the time, make cylinder non-rotating " manual mode " and with the taking-up of sack successful, failure is irrelevant, " the 1 revolving die formula " of whenever going around and just stopping at cylinder.

Main control of microcomputer shown in the flow process of Figure 44 owing to when the setting of the setting of sack height and thrust pressure does not finish, can not carry out earlier, so, after power supply drops into,, carry out the control of sack height earlier according to the diagram of circuit of Figure 45.As shown in Figure 45, at first,, confirm whether the position of jack is correct by jack location confirmation sensor 116.When correct,, make jack, the sack height is in correct state, as finishes this setting, just regulate with microcomputer output " sack height OK signal " to host microcomputer and thrust pressure with motor 131 revolutions according to the ON/OFF signal of sack height affirmation sensor 115.Afterwards, also often monitor the ON/OFF of sack height sensor 115, sack take out and and cylinder between during empty gap of opening more than the specified amount, sack is automatically promoted.

After the setting of sack height finishes, thereupon, carry out the initial setting of the thrust pressure of pressing device 14.This control pushes sensor 123 under the OFF state as shown in figure 46, rotates by the motor 128 that makes pressing device, become ON up to its sensor, thrust pressure is slowly strengthened, and in the moment that becomes ON, the numerical value of just further setting, thrust pressure is strengthened is only the initial value of thrust pressure.This initial value preferably setting state of all relatively sacks becomes high slightly.In addition, how strong last thrust pressure have, with selections simply such as select switches, then best as the operator.Finish as this initial setting, just to host microcomputer output " thrust pressure is set OK ".

Then, the control to host microcomputer shown in Figure 44 describes.After the setting of sack height and thrust pressure finishes, when the operator pushes operation beginning switch (not shown),, confirm whether cylinder 5 is in stop position by cylinder position sensor 41b, when not being in stop position, make the cylinder revolution till stop position.Afterwards, starting aspirating mechanism 3 and wind pushing mechanism 6 become the state that the revolution of waiting for the pushing cylinder begins the switch (not shown).Timer 1 is when certain hour does not push revolution beginning switch, to finish the member of this device operation.

When pushing revolution beginning switch, cylinder 5 revolutions.In revolution, pressure sensor 130 detects pressure in the cylinder when reducing, and means sack by the absorption of cylinder suction inlet, and whether the state that reduces by pressure maintains in the specific time, and the taking-up that can judge sack is success or failure.When taking out successfully, cylinder stops at stop position, becomes the state of waiting for that the operator removes sack from cylinder, in a single day sack is removed from cylinder, cylinder just begins revolution under automatic mode, remove to adsorb sack, when 1 revolving die formula or manual mode, revolution beginning switch becomes the ON state of waiting for.In addition, when taking out failure, cylinder continues revolution up to till success under automatic mode or the manual mode, during 1 revolving die formula, whenever goes around and just stops at stop position.

When not detecting the pressure reduction in the cylinder in 1 commentaries on classics, owing to do not adsorb sack on the suction inlet, for taking-up next time, strong suction a little.Ground also can have no truck with, when after continuous n (predefined number, for example 5) changes, not adsorbing and since consider whether be sack do not have or the height adjustment of sack not smooth, just give a warning, the revolution of cylinder 5 and suction

wind pushing mechanism

3,6 are quit work.In addition, timer 2 is, pushing revolution beginning switch and sack quit work the revolution of cylinder and suction wind pushing mechanism not when cylinder is removed within a certain period of time, become the member of the state of waiting for operation beginning switch connection.In addition, timer 3 is, within a certain period of time, when cylinder does not stop, the revolution of cylinder and suction wind pushing mechanism stopped, and becomes the member of the state of waiting for operation beginning switch connection.

The ON/OFF signal of pressure sensor 130 is also regulated with the microcomputer input to thrust pressure, in this microcomputer, also judges the taking-up success or not of sack, and utilizes its result will push intensity of force to become the control of suitable degree.The right half part of Figure 46 is therewith corresponding, when taking out failure, weakens thrust pressure at leisure, and when taking out successfully, strengthens thrust pressure at leisure.Like this, strengthen thrust pressure at leisure, initial take out failure after, be benchmark thrust pressure and remembered (storage) with a certain amount of thrust pressure that weakens.Be specially, the angle of stepping motor 128 at this moment can be remembered, also can measure the pushing intensity of force and also be remembered by force transducer.So the benchmark thrust pressure of setting becomes the strongest numerical value in the thrust pressure strength range that can take out a sack, afterwards by keeping this numerical value, can do one's utmost to prevent to take out simultaneously the sack more than 2.

But,, also exist the situation of best inching for the thickness of taking into account overlapping sack and adjustment of sack height etc.Figure 47 A, Figure 47 B, Figure 47 C illustrates the example for the diagram of circuit of inching thrust pressure.Figure 47 A illustrates continuous n time and takes out when failing the situation that thrust pressure weakens.Figure 47 B illustrates according to taking out successful past data to control the situation of thrust pressure.In this diagram of circuit, during taking out sack, thrust pressure does not change substantially successfully in good conditionly, thrust pressure is not weakened and takes out case of successful and is remembered.And, be when sack does not have opening continuously, strong a little thrust pressure.In case the enhancing thrust pressure, 2 films of sack can misplace, easily opening.In addition, sack has imperforation by near the light sensors the stop position that is arranged on cylinder.When sack takes out failure, weaken thrust pressure till success, when initial success thereafter, but it is just continuous successful more than the stipulated number whether not weaken thrust pressure when last time taking out successfully, controls thrust pressure.That is, then be that necessary degree ground strengthens the state that thrust pressure just can turn back to this moment, if do not weaken last time just success continuously of thrust pressure.The amount of its enhancing is each all according to the number of times that weakens thrust pressure till success, or last time continuously the thrust pressure during success obtain with the difference of the thrust pressure in the present moment.Owing in a fairly large number of bag, can exist the situation of the sack of taking-up in distress once in a while, thereby this control will taken out the function that can get back to original state fast behind such sack.In addition, when last time taking out successfully, do not weaken thrust pressure and under can not successful continuously situation more than the stipulated number, judge whether to exist difficult once in a while situation of taking out, get back to the state that weakens thrust pressure.The diagram of circuit of Figure 47 C is, is provided with the operator and pushes push-button " enhancing switch " and " weakening switch ", operates these buttons by the operator according to situation, but manual mode change pushing intensity of force just.

Figure 26～Figure 28 illustrates the embodiment of improved cylinder.This cylinder 5 forms in the both sides of columnar cylinder body 64 and embeds ring 65 as shown in figure 27, and ring 65 is laterally slided, just the width L of suction inlet and the size of sack consistently can be changed, thus can be corresponding to the sack of different size.On cylinder body 64, form as the suction inlet 4 of main suction section 7 and auxiliary suction portion 8 and be distributed in the front and back of gyratory directions.Main suction section 7 is made of the mutual closely a plurality of less suction socket 66a that are arranged on the cylinder body 64.Auxiliary suction portion 8 is, gyratory directions front side in main suction section 7, be provided with under the state side by side at circumferencial direction at the suction socket 66b that laterally is equipped with the interval, front side with the row of suction socket 66b between the row of the suction socket 66b of the inner face of cylinder body 64 and row is pasted with banded spacing body 67a, 67b, also on spacing body, be pasted with crooked plate 68, so, form the air flue 69 that is communicated with main suction section 7.The auxiliary suction portion 8 that forms so just when main suction section 7 is plugged because of the absorption of sack, produces suction by air flue 69.

Also around cylinder body 64, be formed on and laterally be provided with raised line 70 at interval at circumferencial direction.Raised line 70 forms on cylinder body 64 and embeds rubber wheel.In addition, the rear side at gyratory directions of main suction section 7 is provided with the adhesion parts 71 of length in horizontal band shape.About the edge part of ring 65 inboards form flange plate-like portion 72.Figure 29 is illustrated in the state of the suction inlet 4 adsorption plastic bags 1 of this cylinder, and Figure 30 illustrates the enlarged drawing of the X portion of Figure 29.On plastic bag 1, form vertical wrinkle by raised line 70, thus, can between 2 films of plastic bag 1, produce gap a, enter air state easily owing to become in the inside of plastic bag 1, under the wind effect of wind pushing mechanism 6, the opening of plastic bag 1 is opened reliably.In addition, the bight between raised line 70 and cylinder surface is only with first film of adsorption plastic bag 1 under the state of empty standard width of a room in an old-style house crack b, and the suction by gap b plays the effect same with auxiliary suction portion.In addition, where the corner part 73 that the flange plate-like portion 72 by ring that enters in the both sides of the edge of plastic bag 1 forms also is adsorbed on by brute force, and the plastic bag that adsorbs by the wind of accepting wind pushing mechanism 6 can arbitrarily not peel off.In addition, cylinder 5 also can not be the form that embeds ring 65 on cylinder body 64, but can change the width of suction inlet by pasting adhesion zone and clog suction inlet at cylinder surface.

Figure 13 illustrates the mechanism of assisted plastic bag 1 opening.The swing arm 50 of swing is provided with rubber rollers 51 synchronously along with the revolution of cylinder 5, the plastic bag 1 that passes through with rubber rollers 51 frictions from the top, but the film in the outside of stretched plastic bag 1 so that peristome open naturally, thereby under wind pushing mechanism is carried wind action, the easy opening of plastic bag.Figure 14 illustrates another mechanism, and at this, the rear side at suction inlet 4 of cylinder perisporium is provided with elastic protrusion 56, and is same by projection 56 and fairlead 53 friction plastic bags 1, makes plastic bag 1 opening easily.

Figure 32 and Figure 33 illustrate the bag maintaining body 97 that is keeping by the plastic bag 1 of cylinder 5 absorption and opening.This bag maintaining body 97 is, can with the push part 100 that contact around the cylinder 5 by actuator 101 actions, when the sack opening, be adsorbed on the both side edges portion of the sack 1 at suction inlet 4 places by push part 100 pushings, can prevent sack 1 disengaging cylinder 5.Adopt this bag maintaining body 97,, also can not break away from cylinder 5 because of this weight make sack 1 even when in the sack 1 of opening, dropping into heavy slightly article.By the revolution interlock action of actuator 101 with cylinder 5, push part 100 just contacts with cylinder 5 when being necessary, removes in addition, throws off cylinder 5.
