Description

Wrapping machine
The invention relates to wrapping machine, particularly about using the wrapping machine of the outer box of transparent plastic film containers of cigarettes.
According to characteristics of the present invention, a wrapping machine comprises the conveyer that transmits the packing object of placing at interval along a passage continuously, continuously wrapper is sent to the device of described packing object, on this passage, determine the device of the first of wrapper with respect to the position of packing object, and for make wrapper at least can be on the part of packing object tensioning and make the device of the second portion of wrapper with respect to the packing movement of objects.In a most preferred embodiment, this packing object is box-like package, and the back all is referred to as package for convenience's sake.The registration device of preferably determining wrapper first position is the part along channel transfer package device, and can comprise a propelling unit easily, and this propelling unit acts on the rear portion of the package of part packing.Propelling unit also can FOLD AND PACK paper first be adjacent to the rear portion of package.Make wrapper produce the device that moves and comprise at least one areal of support, this areal of support is with respect to the second portion motion of wrapper, and the friction force between wrapper and areal of support produces enough pulling force makes wrapper center on the package tensioning.This areal of support may be static, also may move, and for example, the part wrapper can contact with the conveyer that moves with certain speed, and this speed is different with the speed of package.Friction between areal of support and wrapper is preferably low relatively, in order to avoid break trade mark or damage wrapper.An above areal of support can be arranged, and for example, the package that is centered on by wrapper can pass through between two areal of supports up and down, and each areal of support all trends towards the wrapper of tensioning around package.Applying light pressure between areal of support and package is possible with the tension effects that increases wrapper.
During beginning package packed, use sliding surface or other areal of support to guarantee the degree of tension particular importance of packing.So registration device can be used as the first folding propelling unit.Yet the degree of tension that keeps packing is up to the last sealed position of wrapper, and this is very important.At least during article one joint seal of wrapper, resemble the such device of one or more slip planes, finish, can make the present invention obtain maximum interests up to sealing by means of use.Wrapper is made by thermoplastic material, overlapping seam on the wrapper is to come leak free by heat, the most handy heating propelling unit transmits package, and this propelling unit mobilely overcomes very little resistance and contacts with seam by what one or more areal of supports produced, as described in the previous paragraph.The additional benefits of Huo Deing is that this very little friction force has been guaranteed good contact the between propelling unit and the seam in this case, becomes more convenient so that make to conduct heat.
According to another characteristics of the present invention, a continuous wrapping machine comprises at least one propelling unit, this propelling unit is pushing away a package of part packing, along one is straight passage reach substantially, this propelling unit has comprised during transmitting package, by means of heat conduction between propelling unit and the wrapper lap, make this lap leak free device.Heating may work to sealing (for example, thermoset material or thermoplastic material, these may be packing self or the adhesion agent that uses).In this case, propelling unit preferably is made of electric heating element, and can combine with the device of control electric heating element electric current, to keep being suitable for the range of temperatures of package and wrapper.Be appreciated that under the situation of using thermoplastic material, seal process is similar to welding, material cooled process is subsequently solidified hermetic unit.Because in the ordinary course of things, the required heat that applies is very little, so this cooling of very fast at ambient temperature generation.On principle, also can use the cooling propelling unit, for example, make the very fast curing of the fore-warming adhesion agent that is applied on the wrapper.
According to another characteristics of the present invention, wrapping machine comprises the device that the package order of placing is at interval constantly moved along passage, also having with package has some cycles relation ground to transmit the device of wrapper by this passage, so that package can intercept wrapper, wherein said mobile device comprises that relative conveyer constitutes, the position of this conveyer is substantially in the place ahead that is nestling up package intercepting wrapper so that this conveyer can with each two relative faces of the packaged package of part contact.This relative conveyer preferably acts on each on the packaged package of part haply simultaneously.In the process system of prior art, above-mentioned relative conveyer (if really exist) separates far away being in package intercepting wrapper place.Different with this process system, wrapping machine of the present invention is after package intercepting wrapper, keep control as much as possible to wrapper, and allowing has the areal of support of certain speed to contact with wrapper with respect to package: (for example per minute can be handled the wrapping machine of 400 above packages) that this is useful especially to high-speed packaging machine.
According to another characteristics of the present invention, wrapping machine has a straight substantially passage, the package order constantly moves along this passage, for the package that moves on this passage can intercept wrapper, the device that continuous transmission wrapper also should be arranged, make in addition around the device of the wrapper fold seals of package, it comprises first propelling unit and second propelling unit that package is moved along this passage, described second propelling unit then first propelling unit continues along this channel transfer package, described first, second propelling unit has complementary shape, allows each propelling unit to contact with the different piece while and/or the extension of this package.The first, the second propelling unit preferably has constant speed, and the second angle of rake speed is not less than the first angle of rake speed.At least one of them can carry out folding operation to wrapper, so as with the folded part that reaches wrapper at least in part that contacts of the extension of package, and this contact helps its folded part is fixed on the due position of package.In order to seal crease, have at least a propelling unit to comprise the element that heat can be passed to (or spreading out of) wrapper folded part, and can partly finish sealing at least the wrapper that centers on package.
According to another characteristics of the present invention, in wrapping machine, be useful on the conveyer that order transmits the packing object, these conveyers have common channel part, these devices are by independently actuating device driving, by at least one is controlled in the described actuating device, the phase place and the rapid change of conveyer can be made, the change in location that transmits the packing object between the conveyer can be made especially.The cycle of conveyer contact object is controlled.For example, if the speed of wrapping machine is variable and has a conveyer that the heating propelling unit is housed, this propelling unit applies heat so that its lap is sealed to wrapper, then the control of this actuating device allows the time cycle is controlled, so that can be irrelevant, transmit the heat of steady state value substantially with the speed of wrapping machine.
The present invention part or all characteristics may be on a wrapping machine be used in combination in mode arbitrarily.Though in conjunction with box-packaged wrapping machine of the present invention has been described especially, but the present invention can be applied to pack the various wrapping machine (being used in tobacco industry or other industry) of other packing object, and " package " that relates to here, " wrapper " and " packing " should have correspondingly to be explained.For example, the present invention can be used for packing bundled cigarette, promptly is used on the cigarette-packaging machine, or is used for soap packing machine.

The transparent membrane that is to use thermoplastic material shown in Figure 1, the machine of the outer box of containers of cigarettes.
This wrapping machine comprises film roll mechanism 10, and this mechanism 10 has two film rolls 12,14.The film tail end that engaging gear 16 is used for the reel 12 that will use and the front end of replacement reel 14 couple together (and also can oppositely be connected).
Walk around several transmission and belt tensioning drum is delivered to feed cutting mechanism 20 from the film band 18 of film roll mechanism 10 output.At the inlet of feed cutting mechanism 20, the tear tape that draws back goods packing from being convenient to of sending of tear tape reel 24 is sent on the film band 18.Before being sent to film band 18, tear tape will pass through hot cured applicator 26.Charging cutting mechanism 20 comprises cylinder 28 and counting drum 29, and these two cylinders lump together tear tape 22 is pressed on the film band 18, and heat is curedly sticked together them.A narrow cutting blade 31 is housed on the cylinder 28, is used for tear tape and following film 18 are severed, tear head so that on complete wrapper, produce one.
Feed cutting mechanism 20 comprises a pair of feed cylinder 32 that is positioned at below the cylinder 28,29.Cylinder 32 has been controlled the speed that film band 18 and tear tape 22 down transmit from the reel 12,24 separately.Be rotary cutter 30 below cylinder 32, rotary cutter 30 is sequentially with film band 18(and with tear tape 22) fore-end cut off and form wrapper 36.Cutter 30 acts on the reverse side of film band 18 or relative edge's edge (not shown).The feed strip 34 that is provided with at interval by a pair of side and a pair of similar feed strip (not shown) relative with feed strip 34 match continuous wrapper 36 along a vertical substantially passage toward drop-down, so that wrapper is transmitted between a pair of belt conveyor that separates a determining deviation setting in the side.The speed of feed strip 34 of pulling wrapper 36 slightly is higher than the feeding speed of cylinder 32, so as to make each wrapper and film band 18 not cut-off parts separate certain spacing.
Feed strip 34 is sent each wrapper into the passage of package (not shown), and this package transmits along horizontally extending baling line 37.Receive package above lower floor's belt conveyor 40 of baling line 37, make its reach and propelling unit 42 acts on the rear portion of package.The package of receiving on belt conveyor 40 perhaps comes stocking mechanism or other works of comfortable cigarette-packaging machine outlet setting from cigarette-packaging machine.Have two big relatively bottom surfaces of area, two relative narrow limits and two ends if each package all regarded as, then the orientation of package should be that two bottom surfaces are levels, two end parts parallel is in baling line 37 travels direction, and, as described, the back of each package is subjected to the effect of propelling unit 42.
Upper strata belt conveyor 38 is positioned at the top of belt conveyor 40 carriage direction forebodys.The setting of the propelling unit 42 of belt conveyor 38 matches with the propelling unit 42 of belt conveyor 40.The cycle of propelling unit 42 and cutter 30 and feed strip 34 and belt conveyor 38, the front that the determining of 40 relative velocity makes each package fits with the central authorities of every wrapper 36 substantially, and every wrapper 36 is pushed between upper flat plate 44 and following dull and stereotyped 46 side face of wrapper 36 passages of these two flat boards between feed strip 34.
So, packaged paper 36 parcels of the front of package and upper and lower surface, and wrapper 36 also has the elongated end freely that is parallel to the package upper and lower surface.The propelling unit 50 of and then dull and stereotyped 44 upper strata belt conveyor 48 acts on the upper strata free end of wrapper 36.Free end above the propelling unit 50 FOLD AND PACK paper 36 is adjacent to the back of package, and forwards package along baling line 37.
The aft section of the previous section of upper strata belt conveyor 48 and lower floor's belt conveyor 52 is overlapping, and lower floor's belt conveyor 52 is faster than the transfer rate of belt conveyor 48.Cycle arrangement between propelling unit 52 and the propelling unit 54 makes the free end below every wrapper of propelling unit 54 promotions 36, and with its upwards folding back that is adjacent to package, the length of wrapper 36 should make following free end and top free end overlapping and be fixed in (by means of propelling unit 54) on the due position.
The heated belt 56 on upper strata is equipped with electrothermal propeller 58, and the previous section of the aft section of this belt conveyor and belt conveyor 52 is overlapping.Belt conveyor 56 is faster than the transfer rate of belt conveyor 54, and heating propelling unit 58 acts on the lap of wrapper 36 at each package rear portion.During propelling unit 58 transmits package, there are enough heats to pass on the thermoplastic material of wrapper lap, make that part be sealed.
In the previous section of heated belt 56, the transmission flat rubber belting 60 of lower floor transmits package, and this belt conveyor is identical with heated belt 56 speed, and when propelling unit 58 transported package, this belt conveyor held up package.
On the position of heated belt 56 previous sections, the package that transports on belt conveyor 60 has the barrel-contoured part packing of unlimited rectangle, and this barrel extends in the outside at package two ends.Each end all has upper and lower surface and front and back dual-side.The peripheral velocity of rotary type folding device 62 is faster than the direct speed of package, and this folder 62 acts on the back side edge part of end and it is folded the end that is adjacent to package.Fixing plow-shape folder 63 acts on the front side edge part of end and it is folded the end that is adjacent to package, and, in rotary folding device 62 exits in position with folding back side edge partial fixing.Then, the lower part of plow-shape folder 64 first FOLD AND PACK paper, the upper part of FOLD AND PACK paper covers on folding lateral section then.
Behind plow-shape folder 64, each package passes through between a pair of driving band 66, and this rotating band is gone up in position with the folded end of wrapper is fixing, and with temperature booster 68 to its heating, make the folded end sealing of package, so finished the packing of package.
Packaged package is sent to next step Fabricating machinery from belt conveyor, for example, and packing machine or compress.
What Fig. 2-7 showed is the part of improved wrapping machine.This wrapping machine is similar to wrapping machine shown in Figure 1 in many aspects.
Wrapper is delivered to vertical channel 100 and along this channel transfer, this is similar to the transmission of wrapper 36 among Fig. 1, lower floor's belt conveyor 140 is equipped with among the equal propelling unit 142(figure of spacing and only illustrates one), the areal of support 141 that this belt conveyor is provided with package 101 along the side continuously at interval transmits, and pass across path 10 0, so that package 101 can cut mutually with wrapper 136, and this package 101 enters the following band of upper flat plate belt conveyor 148 and going up between the band of lower conveyor belt 145, and upper conveyor belt 148 is equipped with among the propelling unit 150(figure with certain intervals setting and only illustrates one).Belt conveyor 145 and 148 is almost near path 10 0, at package 101(together with wrapper 136) by after the path 10 0, its front end is transmitted soon is with 145 and 148 to clamp.Obviously, because the circular arc of belt pulley bending, when package 101 makes after wrapper turns back, belt conveyor 145,148 can not touch wrapper 136 immediately.In order to address this problem, be provided with lower guide plate 144,146, they have slight curving leading edge, and these two guide plates define only slightly high than the height of package 101 opening, in addition, also guarantee wrapper 136 good initial package state on package.The position of the drive pulley of belt conveyor 145 be set directly at top small belt pulley below, and not coaxial to the belt pulley of belt conveyor 152: can use the full duration (promptly similar) of propelling unit 154 like this, because propelling unit 154 has been excluded with the possibility that belt conveyor 145 takes place to disturb to the propelling unit 154A of Fig. 8.
Belt conveyor 140,145 is identical with 148 linear velocity.The cycle of propelling unit 150 arranges each propelling unit can be withstood on rear portion, the upper strata 136A of wrapper 136, and it is its upper strata rear part edge along package 101 is folding, next make it be adjacent to limit, the back portion of package, meanwhile, the rear portion that propelling unit 150 is pushing away package 101 has the areal of support 153 that is provided with at interval to advance along the side, areal of support 153 originates in the front portion of belt conveyor 145 upper stratas operation minor face.When wrapper upper strata rear portion 136A was fixed on the back part of package 101 by propelling unit 150, the friction force between the underclad portion of wrapper 136 and the areal of support 153 ordered about and guarantees that wrapper tightly encases package.
The front end that lower floor's belt conveyor 152 with the propelling unit 154 that is provided with at interval is arranged on belt conveyor 145 has been installed.The linear velocity of belt conveyor 152 is higher than the linear velocity of belt conveyor 148.The cycle of propelling unit 154 determines, so that each propelling unit 154 can be contacted and it is upwards folding with the rear portion 136B of lower floor of wrapper 136, covers in the back of package 101 part, and is overlapping with previous folding top section 136A.Subsequently, propelling unit 154 promotes packages 101 and transmits on areal of support 153, and this propelling unit 154 is fixed on the appropriate location with the overlapping wrapper that encases package 136.Along with propelling unit 154 transports package 101, the lower surface of areal of support 153 and belt conveyor 148 contacts with wrapper 136, to its retentive control, and it is packed tightly, and is similar to the situation during propelling unit 150 transports.
Conveyer chain or the belt conveyor that warming and transporting unit 156 is provided with at interval by the side and be in the heating propelling unit 158 that the interval between the belt conveyor is provided with and form the front position overlaid of this warming and transporting unit and areal of support 153 and belt conveyor 152.Spacing between the belt conveyor of conveyer 156 is greater than the width of wrapper 136.Conveyer 156 is compared with belt conveyor 152 has higher linear velocity, and the setting of propelling unit 158 can contact this propelling unit 158 with the back part of each package 101, and this propelling unit 158 then propelling unit 154 continues to transmit package on areal of support 153.Heating propelling unit 158 contacts with the lap of wrapper 136, and makes this lap be sealed with enough heats during transmitting.Propelling unit 158 extends to the side, and this extendible portion is passing through between the both sides up and down, and this part has been improved the rigidity of conveyer 156 lower floors operation parts, and plays directional tagging and prevent the propelling unit vertical shifting at run duration.
Propelling unit 158 is electrically heated, and with the end of package moving contact is arranged, and this end acts on (shown among the figure 159) on the fixed sides guide rail.Electric current by propelling unit 158 is well controlled, so that keep suitable range of temperatures (generally being 120-160 ℃) on propelling unit; Obtain temperature controlling by control voltage, and will apply electric current during this period.Propelling unit 158 has relative high caloic.
During propelling unit 158 transmitted, the top section of wrapper 136 and package 101 were subjected to the control of static surface 157.These surface 157 direct contacts cover the part wrapper above the package 101.Yet, preferably have elastic force that package 101 is pressed on the areal of support 153.Therefore, with pinch device 180 be attached to the surface 157 below, Fig. 9 and Figure 10 have represented this structure preferably, and this pinch device 180 is equipped with hairspring 182 and heads on surface 157 and contact with package, so package 101 is being pressed on the areal of support 153 under the light pressure effect.Though the lower surface of pinch device 180 (having four these devices along propelling unit 158 running length serial arrangement) and areal of support 153 by the material of relative low-friction coefficient (for example are, corrosion-resistant steel) makes, but, try hard to keep at some additional frictions that cause of exerting pressure on the package 101 and to have demonstrate,proved good contact between each propelling unit 158 and the package 101.During propelling unit 158 transmits packages 101, pinch device 180(or surface 175) and the resistance of areal of support 153 generations help to keep the wrapper tensioning, till sealing is finished.
The previous section of warming and transporting unit 156 and next lower floor conveyer 170 overlaids are equipped with propelling unit 172 at regular intervals on the conveyer 170.For the transmission that makes package can carry out the transition to propelling unit 172 with propelling unit 158, conveyer 170 has the linear velocity higher than conveyer 156.
Conveyer 140(also has 145 and 148) and 152,156,170 speed be 1: 1.20: 1.33 than approximately: 1.40.The spacing of (with at the propelling unit of conveyer separately) also has same ratio between the package.Conveyer 140,148,152,156 and 170, the propelling unit that each device all has four equidistant from distance.
Reduce or eliminate a pair of or several propelling units 150 to order, 154,158, speed difference between 172, thereby reduce or eliminate their speed differences between the conveyer separately, may be an advantage, doing like this be in order to reduce the impact on the package 101, the slip of wrapper 136 with respect to package may to occur thereupon.This when promptly transmitting, has special purpose between propelling unit 150 and 154 when initial transmission.In this example, conveyer 148 and 152 is with the operation of identical speed (this comprise the gap length between the propelling unit 154 is reduced to gap length between the propelling unit 150), this has potential further advantage for expansion drags package 101 and wrapper 136 on areal of support 153 cycle, thereby has also enlarged the benefit of tensioning with the control packing potentially.
Each conveyer 140,148,152,156,170 all is to be made of timer-operated belt conveyor (or belt), and is opposite with conveyer chain, uses these transmission to have bigger plasticity, thereby also helps to reduce potentially the collision to package 101.Belt conveyor has further advantages than conveyer chain.Be belt conveyor can with wrapper 136 direct contacts, and control wrapper 136 and package 101, for example, as using belt conveyor 148 and 170, and make areal of support that package slides (for example thereon, areal of support 153) and convertible between the areal of support (for example, belt conveyor 170) that directly transmits thereon of package.
Propelling unit 142 and 152 generally has simple rectangular section, as shown in Figure 3.Propelling unit 154,158 and 172 has complementary shape, and as shown in Figure 4 and Figure 5, this helps to transmit and permission has enough contacting with package, though each in them might be simple rectangular shape all, it is such to resemble propelling unit 142,152.When attention transmits between two propelling units, two propelling units will contact (or because velocity contrast has been eliminated substantially, contact simultaneously can be arranged then for a long time) at short notice simultaneously with each package.
Areal of support 153 can extend to always the left side, as shown in Figure 2, thus conveyer 170 can be installed in this extension areal of support below, this is the same below areal of support 153 with belt conveyor 152.(so conveyer 170 preferably is made of the mono-main belt, replaces side belt conveyor at regular intervals, as shown in Figure 6).And then, this plane of slip plane 149(, upper strata is set near belt conveyor 148 can comprises side part at regular intervals), so that propelling unit 150 reach this slip plane 149 below, but this slip plane 149 belt conveyor 148 lower floors transport the part below so that it can with contact by the wrapper on the package 101 136.Conveyer 148, plane 149 and propelling unit 150 can have part that the side is provided with at interval to achieve the goal.Plane 149 and plane 157 be on a level substantially.Slight additional friction power between the static plane below part wrapper 136 that is centered around package 101 upper surface and belt conveyor 148 tightly has further help to the degree of tension and the control of packing.Upper strata control plane 149 preferably originates in the place that propelling unit 154 contacts with package 101 at first, perhaps originates in this local the place ahead.Plane 149 extend to belt conveyor 148 fwd belt pulleys below, keeping the control to wrapper 136 top section, this plane 149 is as far as possible near the path of heating propelling unit 158.
Referring now to Fig. 6 and Fig. 7,, the fwd part machine that is arranged on machine shown in Figure 2 of these two figure expressions, conveyer 170 transmits package between the rotary folding device 162 that forms wrapper folded end aft section.Folder 162 has two parts 161 up and down at regular intervals, (Fig. 7), during folder 162 rotations, these two parts pass through the both sides up and down of fixed fold device 162 respectively, forming and to keep the shape of the previous section of folded end, and keep the shape of folded end aft section.Folder 163 has the introducing targeting part 163A between the parts 161 that reach folder 162.The rear portion curved surface of folder 162 is used for the aft section of folding part being clamped and locating, and takes over it up to fixed fold device 163 and rises and clamp the location.With the short belt that folding element is housed or use have the up and down two-part folded piece similar to replace folder 162 can strengthen this effect to parts 161.Air nozzle helps the function of folder 162: these air nozzles may be fixed, and also can be installed on the folder 162.Fixing plow-shape folder 164 is finished the folding of top and bottom, end.The folder 62,63 of folder 162,163 and 164 operation and machine shown in Figure 1 is similar with 64 operation substantially.
During package was sent to relative belt conveyor 166 from conveyer 170, folder 164 fwd side plates 165 were fixing in position with the folded end of wrapper, the folded end contact that belt conveyor 166 is relative with each package.168 pairs of belt conveyor 166 of heat block that the electric heating chuck member is housed heat, and make package when passing through between the belt conveyor, seal its folding end.The material of belt conveyor 166 is generally steel or has soaked into the glass fibre of polytetrafluoroethylene, and the material of selection should have the performance of enough permeability of heats and Ke Nai higher temperature.Heat block 168 constitutes (as shown in Figure 6) by heater block independently, and the heat that is applied to belt conveyor 166 is had stronger control ability.It is telescopic that one or more parts are arranged, and these parts or heat block 168 are equipped with the spring bearing load (shown in 168A among Fig. 6) towards belt conveyor 166.Can guarantee the rational constant pressure between heat block 168 and belt conveyor 166 like this, also guarantee the rational constant pressure between belt conveyor and package, and the subtle change that helps to regulate package length (between the two ends).The thermal radiation temperature booster, for example halogen heater can replace heat block 168, perhaps to 168 supplementary function of heat block.Heat can be sent to the belt conveyor 166 of (perhaps, also can spread out of) revolution operation, helps temperature control.
Be appreciated that each conveyer 140,148,152,156,170 all has and the adjacent aft section of self work operation part, play supporting role to belt conveyor.That conveyer acts directly on is very beneficial on the package 101 that is transmitted (for example, conveyer 170 shown in Figure 2 and the conveyer 148 during not with plane 149).Theoretically, aft section needs not be straight.For example, if the belt pulley of conveyer 148 is contained in the place higher than position shown in Figure 2, for the face that returns of the projection that begins can make propelling unit 150 progress into their control position, the work operation part of conveyer 148 should move down.When length a part of of conveyer 148 lower floors operation part only extended on plane 149, belt pulley 151 can be contained in the place slightly higher than belt pulley 155, and aft section has one section (promptly near belt pulley 155 the place aheads one section) parallel with plane 153, slightly upwards face toward belt pulley 151 at a certain angle, thereby controlled the part of the close belt pulley 151 of the conveyer 148 lower floors operation on plane 149.Preferably directly contact with package 101 with wrapper 136 from belt pulley 155 beginning propelling units 150, and conveyer 148 lower floors operation part does not preferably have amount of deflection, 149 beginning partly is such on the plane at least.
Because it is to carry out with reference to the back part of package that the cycle of wrapping machine arranges,, an advantage of this wrapping machine needn't adjust because of the change of package width (that is, between the package both sides) so being the conveyer that transmits package.The variation of package length direction is relatively easily regulated, and for example, uses the method that has the belt conveyor of spacing to remove the side.If not to the movable members adjustment but adjust retaining element, then the variation of package height (that is, between the two sides) also can reduce the influence of wrapping machine.With reference to figure 8, this figure is that the section-drawing of some improved devices has been made in VIII in the being equivalent to Fig. 2-place of VIII line, and areal of support 153 can vertical shifting, to adjust the distance between it and the belt conveyor 148 lower floors operation parts (also having plane 149).Conveyer 148 and 152 position remain unchanged.The distance of noting being in the propelling unit 154A top of the belt pulley 174 diameters top that belt conveyor 152 walks around is smaller (for example 3mm): when propelling unit when belt conveyor work operation end is walked around belt pulley, do the acceleration/accel that can reduce package on the areal of support 153 like this.
At least the variation of some size is carried out automatically.Start to control the microprocessor of making usefulness with button with size or about the code input of known package part size.Monitor the package that relates in turn, for example, on wrapping machine or the place of contiguous wrapping machine opto-electronic pickup is set so that carry out suitable adjustment in the relevant size to the control system on the wrapping machine after the monitoring, for example, a reference package spare is sent in the monitor unit monitored.The relevant sensor that monitors package after the sensor of monitored position and packing cooperates guaranteeing that packing is consistent, and this parts also can be used for whether unanimity of printed patterns that wrapping machine checks package.
Cycle relevant between the conveyer very strictly arranges, and it is even more important particularly to transmit this problem of these positions of package between conveyer.Can be with public engine drive conveyer with suitable gear system.In other words, can use independently actuating device, can be automatically controlled to keep certain cycle to arrange.On the wrapping machine of Fig. 2-7, these methods are combined use.The belt pulley of the first public engine drive conveyer 148,152 and 156 back, and the guiding belt pulley of drive transmission unit 140 and 145.The guiding belt pulley of the second public engine drive conveyer 170, the back strap wheel and the rotary folding device 162 of belt conveyor 166.
An advantage of individual drive device is: in the overlapping place of conveyer, this place's fwd conveyer continues to transmit package, is easy to control these conveyers with the phase place of adjusting actuating device with the method that changes the angle of rake relative position of each conveyer.In habitual drive scheme, each conveyer all links to each other with a shared driving engine, controls conveyer like this with much more difficult.For example with regard to the situation of conveyer 156 and 170, these conveyers all are individual drive, and lap is also more more than shown in Figure 2.So the phase place of actuating device is variable (in the machine zero load), makes propelling unit 172 can follow propelling unit 158 sooner or later and continue to transmit package 101.In this respect, be adjustable between the week of heating propelling unit 158 contact packing parts 101.This is a useful convenience, particularly when the wrapping machine running velocity is variable, because might keep the contact time of propelling unit 158 constant relatively, otherwise will control contact time as required by this way when wrapping machine speed be different.Might change the relative velocity of conveyer one by one at an easy rate with individual drive device, but, usually on a cover conveyer, need refill-unit at least, because the spacing on the conveyer between the propelling unit is relevant with the speed of conveyer, that is, the spacing between the package changes with transfer rate.
Should be noted that when propelling unit 142 is also kept in touch with package 101 and begin around conveyer 140 front pulley movements, can produce slight speed course latitude error.A kind of method that overcomes this problem is the speed of control conveyer 140, makes it slow slightly at this period velocity, with the speed of compensation package increase.Obviously using independently on conveyer 140, electric driver is easy to accomplish this point.Another method that addresses this problem is to load onto sweptback guide surface at the propelling unit 142 of conveyer.After being to use what is called, another kind of possibility turns over the propelling unit conveyer, and perhaps simpler, connecting rod is set to keep propelling unit vertical on parallel belt conveyer.Also can make conveyer 140 more slow slightly, separate with propelling unit 142 immediately after being clamped by these follow-up conveyers with convenient package than the speed of conveyer 145 and 148.Do not rely on the propeller structure of speed regulating device or relative complex, can alleviate this problem yet and reduce the height that propelling unit exceeds front belt pulley effective diameter, as above in conjunction with Fig. 8 narrated.
