Description

Packaging facilities and packing method

The present invention relates to the device that the packing of product is used.

Applicant's etc. common pending application PCT/GB90/00266(WO90/09316) number is related to an invention: make product or group of products by the intersegmental distance between input and output usefulness conveyer, and when in this segment distance, getting spiral circumvolution form, belt by this segment distance of passing through is supported, and this strap finally is also coupled in the interior packing of this spiral circumvolution part.

On the implementation in the invention, when a collection of product of promptly generally getting cylindrical shape with rounded bottom and sidepiece, at its direction of transfer of crosscut and set side by side and need carry out multi-packaging to them time, problem appearred once on this direction of transfer.This is because concerning certain a few these class package; deletrious moving takes place in this regular meeting on its direction of transfer of product; simultaneously; the final package that forms can make product become false relation from the state displacement of horizontal side-by-side alignment; the product of one side is fallen on the top of joining mutually between the opposite side product, even these products are being extruded under the contact condition of desired maintenance on the direction of transfer mutually.A kind of like this deleterious effects occurs in the spiral circumvolution packaged form, but the applicant finds that this is with the employed load-transfer device that goes in the packing and irrelevant that finally is attached to; But evidence suggests that problem is to fail to distinguish effectively which part product is in advancing or in retreating, and also is to know on this load-transfer device or even difference that cause because of tension force on its width.

One object of the present invention promptly is to solve the peculiar problem of the spiral circumvolution packaging process of above-mentioned this generic.

Packing technique total component part according to the present invention, when making it to be adjacent to carry out grouping package at its direction of transfer and in this direction of transfer of its crosscut for the product that transmitted a spiral circumvolution multiple package position, relate in the crosscut direction of transfer product that not so neighbour is pasted is separated, this is to be so in this section process that adopts spiral circumvolution packing at least.

In other words, the invention provides a kind of method of the group products that is provided with the relation of side-by-side along a direction and this direction of crosscut in order to packing, at this product in groups continuously is sent into along a said direction mutually, by one adopt therewith direction roughly the strip material of crosscut it is carried out the station of spiral circumvolution, wherein being at least in carrying out spiral circumvolution packaging process, is that the product that not so neighbour is pasted on the direction of the above-mentioned direction of crosscut is separated with some at least.

Therefore, the present invention also provides a kind of method that is used for packing the product of supporting form: the product that this kind opened by component in one direction sent the intersegmental distance between two transfer systems mutually continuously, carry out the station of effective helix angle formula circumvolution packing by an energy by the pass through material of this intersegmental distance of the above-mentioned direction of crosscut simultaneously, group of products wherein is included in sends into direction and product adjacent in the direction of this direction of crosscut, and those are sent into the product that not so neighbour is pasted in the direction in crosscut and are then carrying out at least being separated in the spiral packaging process.

Generally, when the product that will be in the crosscut direction of transfer not so the neighbour be pasted is separated, relate between the adjoining product of this class one or more dividing plate is set, to reduce the exposure level of product and product.It is to be inserted between the product before product just in time enters spiral circumvolution multiple package position at least that this baffle plate device can be arranged to.Another component part of the present invention then is that this class package member is provided, and comprises the baffle plate device that is located between adjacent product.

According to one embodiment of present invention, this kind baffle plate device is used a kind of product separator, this kind separator is to extend along the direction of transfer of product between product, and not so these products just will be at least when carrying out spiral circumvolution and pack, phase close neighbour in the direction of this direction of transfer of crosscut.If in the direction of this direction of transfer of crosscut, the product in every group then can have more than a separator more than two.

The formation pattern of this product separator can be agreed to the shape of adjacent product and be changed.

In this embodiment, needing to adopt above-mentioned separator is because spiral circumvolution is packed this special shape and caused, like this, the group of products of packaging will produce horizontal compression power, usually, wherein some is used for making this spiral circumvolution packing drawout, each such separator is extended simultaneously reach the total length of importing with conveyer this moment is favourable, and preferably further this kind packing are fixed in its end or beyond the end, it is being opened from this extension through a spiral circumvolution make-up room every when conveyer is used in output, except its base is able to may fall effectively this output with on the conveyer, no longer be subjected to any supporting.Described in this certain embodiments in plan, above-mentioned separator extends to the cooresponding length of group of products length with packaging on exporting with conveyer.Be for output is withdrawn out packaged group of products effectively with transmitting function from separator, can also be used for equally effectively aforementioned load-transfer device is withdrawn from by this packaging system, can supply with conveyer from input easily equally and cross a load-transfer device.

Another kind of can being limited at spiral circumvolution make-up room every interior or satisfy the minimum requirements that product separates and be meeting required upstream or downstream part, usually aforementioned load-transfer device top that is in low level and the said separator of facing are with it hung down from the product orientation device of top, when being used for making the product of input to be able to that the front edge of separator is met therewith by juncture easily, can be along laterally being separated from its direction of transfer.The product orientation device of this class top can wait disclosed the sort of in its common pending application with the applicant, even its downstream part is unfettered, and be fixed in input with the end of conveyer or its neighbouring or be fixed in spiral circumvolution make-up room every starting point, make it helical coil by drawout be wrapped charging wrapped up in around, and this kind material promptly tightens the ground bag and is attached on this set product when in groups product is pumped to output with on the conveyer time.Should know that this kind separator can be from upstream, aforesaid guide piece upper edge or downstream extension, simultaneously/or only be fixed on this top guide piece the upstream extremity place, and be able to freely drift about in the downstream effectively this spiral circumvolution make-up room every, even only be fixed to input with on the end of conveyer or near it, or be fixed to this spiral circumvolution make-up room every the irrelevant starting point place of top guide piece therewith, no matter whether this guide piece exists.

If as the situation in its common pending application such as applicant, when have the top guide piece by spiral circumvolution make-up room every the time, no matter whether be combined with the supporting mass of separator, the extension that exceeds the top guide piece of this kind separator can guarantee that at first from then on each packaged group of products withdraw from the guide piece, and first inevitable outcome that is had is the percentage of elongation that has reduced spiral circumvolution packing; Guaranteed simultaneously when said separator is withdrawn from each packaged group of products, the minimizing of spiral circumvolution material percentage of elongation is as one second and further reduces the result of percentage of elongation and take place, then the product that circumvolution is good applied less power.Applicants etc. be sure of, by reduced between product because of with correctly be positioned with the little residual relative displacement risk that departs from, the jacket that will help carrying out around the packaged group of products of circumvolution series shrinks.Yet the stretching, extension meeting of spiral circumvolution package is grabbed cooperation usefulness to the special actv. that product brings, and is at least departing under the little condition in correct location, can help to keep the stability of the group of products that packages.

In general, the actual (real) thickness that should know said separator is can not bring hell and high water for obtaining required spiral package thickness, and this is because the percentage of elongation of the spiral packing of this kind will surpass when replying after withdrawing from separator needed fully.The PVC(polyvinylchloride that applicant etc. were once thick with 1.5mm satisfactorily) plate is used for experimental developmental work, this is for the separator that extends by two group of products that product became arranged side by side, (the group of products here includes and is in output with first the packaged group of products on the conveyer), also promptly being grabbed fashionablely when its package by two continuous mutually spiral circumvolutions even, is not have any time to remove problem.The material of rigidity, for example steel or even spring steel can be made the separator of Bao Deduo.Can aspect following two, bring benefit like this; Can reduce the final fold of aforementioned load-transfer device in packing, simultaneously can reduce product undesirable displacement risk takes place when being separated from separator, the downstream end of this kind separator is can retrofit tapered, at least be when still not being very thin all, so just can help to reduce any influence that is subjected to displacement at separator.

With regard to top that summarize and content that enumerate one by one, employing among the present invention this component part of product separator, no matter in fact be equivalent to be used for the group of products of circumvolution when whether having adopted load-transfer device, this waits pointed in its common pending application as the applicant, only need supposition to provide supporting at interval in whole spiral circumvolution by having the lower guide that transmits character, perhaps supposition can be otherwise transmits in the lower guide return device of static state and gets final product, in a kind of situation in back, above-mentionedly be fit to be used for the separator that matches with said upper guide, it is combined to plant lower guide equally well therewith.

But, load-transfer device in application applicant's etc. the common pending application, it is believed that the purpose that can more help realizing the above-mentioned few component parts of the present invention, this is because this kind load-transfer device provides unified continuous or conveyor surface, the group of products that collection holds together to this face then can be owing to the product generation relative displacement of this kind transport condition that is provided in causing on the same group, here the position stability of addressing can improve rapidly by adopting such conveyor belt material, and this kind material has at least a in following two kinds of abilities: the bottom of product can produce slight impression at least on this kind material; This kind material can produce adhesive bonding property to the product bottom.

Another component part of the present invention relates to a kind of vertical circumvolution material of special employing or load-transfer device.According to this component part,, need set out overall variation portion value in the vertical circumvolution material between adjacent product in order not so will on the direction of roughly crosscut transmission, to separate mutually by close neighbour's product with the sort of.The packing of producing has so then constituted another component part of the present invention.

The present invention also provides packing for such group of products, product in this kind group of products in a first direction near, and in the direction of this direction of crosscut, above-mentioned packing then includes vertical circumvolution material and spiral circumvolution material, before a kind of overall variation portion of material expand to aforementioned the sort ofly not so between the product with the close neighbour, then a kind of material generally uses by the direction of the aforementioned vertical material of crosscut.

Before product enters spiral circumvolution station, can provide this change section easily among the skim and preferably be covered among the top thin layer of circumvolution material of product.Be suitable for the baffle plate device that this kind packing destination device has product separator or reproducing unit one class, be used for being inserted between this series products and/or be used for the form of replicated product, but can not cause product that the excess in displacement that can not make us accepting takes place or move.For example, a kind of separator of plate-like just is applicable to the product of the wall portion with roughly setting, and a kind of drum member or similar articles then comparatively are applicable to the goods than complex appearance, for example " thin neck " container.

Product to be packaged can suitably apply the vertical circumvolution material that adds one layer or more bottom and/or top, is to be configured in product and to be used for providing overall variation portion and to influence between the equipment that product separates in the circumvolution material and have the such material of one deck at least.So; by aforementioned vertical material is contacted with this kind equipment (a for example separator); and this separator is inserted between the adjacent product; this kind material that so just can take certain-length holds together or turns over Zhe to be incorporated between the product, and has provided the single-piece change section in the certain limit of this layer material.The visual concrete situation of the limit of this change section, form and direction comprises according to the form of adjacent product different.Similarly, adjacent product can be separated by last change section prominent and/or that dash forward down.In this case, different if this kind gone up the limit of prominent with prominent down variable quantity, then above product with below relative linear velocity during the aforementioned vertical material of supply need look particular case and regulate.

Adopt aforesaid the sort of side to have load-transfer device or vertical material of adhesives, be able to stability be improved, so just can obtain gratifying especially result by said change section is adhered at its joint product.

The contrast accompanying drawing is described instantiation of the present invention with way of example below, in the accompanying drawings:

Fig. 1 is the transparent view that the equipment of separator is installed according to an embodiment;

Fig. 2 is used for illustrating problem to be overcome;

Fig. 3 is a planar view, shows the decomposed form of bright Fig. 1;

Fig. 4 is for being used for providing the transparent view of the equipment of overall change section in vertical circumvolution material;

Fig. 5 is a scheme drawing, and the application of the vertical circumvolution material with overall variation portion is described.

Equipment 10 among Fig. 1 and applicant's grade common pending application PCT/GB90/00266 number is disclosed basic identical, simultaneously also will be directly with reference to the latter.This equipment can be when each group of products moves past one section space 16, with continuous circumvolution strip of wrapping material around on group of products, the space 16 here is limited between the downstream end and one second conveyer, 13 upstream extremities of one first conveyer 12, these two conveyers are disposed among the direction of transfer C by delegation, and separate mutually.

Among above-mentioned space 16, there is a dicyclo type strip to stick device 14 around a rotational that parallels with the axis of first and second conveyers, it is able in each group of products 11.1 to 11.N when first conveyer 12 is on second conveyer 13 is come in space 16, on at least one rotating shaft 15, to intend in the packing of circumvolution 15A among at least one spiral fashion band 17(figure, B, Z and 17A, B X) is around on aforementioned each group of products.16 load-transfer devices of pulling out 18 fit with these a few group of products through the space, and preferably can do fitting of gleyness with it, meanwhile, 17 on spiral fashion band in turn is wound up into each group of products and with on the load-transfer device 18, this load-transfer device plays a part rotation, or is convenient to make each group of products 11 to be transferred on second conveyer from first conveyer through space 16.

As shown in the figure, on the spool 21 of load-transfer device 18 from the packaging coiling material that is located at technological process top, in this technological process, thereby load-transfer device 18 is covered input uninterruptedly with this space 16 in the carriage 19(bridging in the conveyer 12, space 16) and conveyer 13 on.This Addon Volume package material that is wrapped from spool 21, can be with similar from the material in the master package material rotating shaft 15, it also can be the flexible material of other type, its purpose is to provide a kind of continuously active surfaces with conveyer 12 and 13 operations, and surface that preferably can be bonding with group of products 11.Conveyer 12 and 13 can be according to the operation of identical command speed, perhaps makes output be a bit larger tham input with the command speed of conveyer 13 and uses the speed of conveyer 12 may be more favourable.

Pending circumvolution packaged products group 11 is delivered to circumvolution with on the packing 18 by product to the spacing 20 of product.At work, group of products 11.1 to 11.N-2 is all done the actv. operation with identical linear velocity with packing 18 and conveyer 12 and 13, if but the running velocity of conveyer 13 slightly faster than the speed of conveyer 12, will be more favourable.

Because group of products 11.1 to 11.N-2 is to be positioned on the packing 18, this does not just have external force and disturbs these products or the spacing 20(between them to be different from the situation of the spiral circumvolution packing that will occur).At least be that group of products 11 can be used as unique means that are pulled through corresponding system with 18 that make in the weight on 18 when conveyer 13 is driven, this is with 18 then can fully satisfactorily these group of products be carried space 16 at conveyer 12 and 13 formed tension force.In practice, particularly for the highly ductile perfect package band 17 of having of those adhesive membrane types, carriage 19 can be used to supporting load-transfer device 18 and comes by space 16, and load-transfer device 18 then can adopt and spiral package 17 identical materials.

In this packaging process, spiral packing 17 will be wound up on group of products to be packaged 11 and the supporting packaging material 18, and this load-transfer device 18 is clipped between spiral strap 17 and the group of products 11, and can partly make the extension degree of this spiral strap 17 obtain substantial recovery at least.Caused the problem that the present invention was concerned about just because of this recovery characteristics.

Fig. 2 shows clear owing to product these problems that deletrious relative displacement causes in direction of transfer, particularly for having the product of shape bottom, garden with sidewall, promptly is roughly columniform product.Specifically, among the group of products 111 of dislocation, former should touching mutually alignedly side by side by side being transverse to the direction of transfer upper side edge is promptly perpendicular to the diameter of direction of transfer (show with the long and short dash line bright) product (101,102 by desirable contact point alignment; 103,104; 105,106), displacement has in fact taken place now, thereby fallen along direction of transfer on the joining of adjacent product.In fact, in case reached above-mentioned state, this a few products even might be forced to depart from direction of transfer, and make the packed products of final gained become the mixed and disorderly thing of a pile.Although except that only utilizing friction, no matter help to resist or limit the displacement of this product by the special localization method of the supporting of bonding or impression and load-transfer device 18, but it usually is not enough to stop dislocation, is at least to be not enough to prevent that the extensibility because of material from causing the load-transfer device distortion to cause dislocation.Utilize two screw-shaped circumvolution packaging rings can increase the weight of this class problem, and if when being reversed circumvolution, equally can be so.From basically, this class problem is because under the effect of the power F that spiral strap applied that stretches, product produces on its position has less not collimation and product slide relative to be arranged each other with due to the rolling.

Reducing this class problem from essence is because the special device that is here adopted for example shown in Fig. 1 and 3, is provided with a kind of separator 30.The separator 30 of this optimised form shown in the figure is installed in the upstream extremity of input with conveyer 12 by an adapter plate 32, this kind separator as shown is a riser, extend downwards, be in by each set product in spiral packing space 16 and between output is with first group of packaged product on the conveyer 13.Separator 30 is the most handy to be passed screw or clamping form and is installed on the pawl card under hanging from above from adapter plate 32, like this, the downstream part of this kind separator 30 just is in a kind of " floating " state, and does not need its bottom free and bearing in being output on the conveyer 13.

Packing shown in Figure 1 are actually and are embedded between product, though from the principle must be not so, a row product of being packed continuously therefrom, each packaged product is for example available to be located at a reciprocal heated filament 24 or the blade on the balladeur train 25 of activity, or cuts packing and make it to separate one by one with any actv. cutter sweep.Complete packaged product just has screw type jacket in its outside this moment, wherein includes the supporting packaging material 18 of a product itself and a monolithic.Use a kind of heating system, for example a kind of heated filament/cushion block/blade assembly is used for to help to seal on all high synthetic plastics packing 17 of extensibility and recovery, though usually and do not require so from two ends to completed package.

Device shown in the figure also has a upper bracket 19A, the second load-transfer device 18A on the product top, and with the double-type top of first and second conveyers conveyer 12A, 13A, they all are the stability that is used for improving load-transfer device and spiral packing, especially for the situation of tall and thin type product.Along being that input is used on the both sides of conveyer 12 at least, in the normally a pair of wall portion that parallels (referring to the 22A among Fig. 3, B), generally also will be provided with other guide piece (not showing bright).

Carriage 19,19A respectively have an actv. supporting arm 22, it extends to a free end at the direct of travel of product 11, and will be 17 circumvolutions of spiral strap equally, this spiral strap can stretch with suitable response rate, make it these products that can unroll rapidly when product leaves gap 16.The low-friction material of polytetrafluoroethylene (PTFE) and so on is available for the surface that is engaged for spiral strap 17 at least.But, the carriage 19 of open core type or be equivalent part with supporting arm 22 at least, when on supplying with pressure gas (normally air) and surface, boring a hole, explained to have special advantage and practicality in the common pending application as applicant etc. at them to their.

If surpassed the width of product to be packaged as the width of the load-transfer device 18 of packing, the side of this kind load-transfer device will be for having special recoverability, on the spiral strap 17 of the adhesive membrane section bar material that can highly stretch volume or under be bent on the product.

The narrow neck type product for example separator of bottle can be equipped with the side extension, is used for engaging the neck of product, and when carrying out spiral circumvolution product is remained in position accurately.If the diminishing product towards the bottom, that just should adopt the separator that extension is arranged at downside.In fact, the two all is useful concerning some product for upside and downside extension, and for those and the strict different product of right cylindrical, even also require the sidepiece shape of this kind separator and product in full accord.

Referring now to Fig. 4,, shows wherein and understands a kind of equipment that has improved that it is by providing the variable quantity adjacent product separation in the upper strata as the packing 18B of load-transfer device.

This kind equipment comprises a frame 38, and the rotating scroll 21B of vertical packing 18B is installed above.This frame comprises a bottom supporting bar 43 (and its corresponding parts on frame 38 relative sides (do not give among the figure show bright)).Bar 43 separates mutually with its corresponding component, gets so that product in groups transmits on vertical strap 18 of frame 38 in the bottom, and has several millimeters of having an appointment between the adjacent product of this its transverse direction of direction of transfer upper edge, for example about 5 millimeters spacing.Outside the outlet of frame 38, be provided with the bar 50(counterpart relative at product with it), the spacing between these two bars is less than bar 43 and counterpart thereof the spacing in frame 38 entrance.

Top in frame 38 rotatably is installed with roller 48 and 49, and they can be located at a kind of either side of adjustable scraper plate 40.If scraper plate 40 is projected under roller 48,49 horizontal surfaces several millimeter.During use, in groups product 11 is installed on the vertical strip of wrapping material 18 in bottom, but has the adhesives of cementitious product on the upper surface of common this material band, this strip of wrapping material 18 is by frame 18 simultaneously, and in groups product 11 is pulled through therebetween.

Vertical material band 18b on top, is covered on the product 11 under the effect of dummy roll 48 from spool 21B.Gap between roller 48 and the product 11 is very little, makes band 18B be on the end face of product 11 at this with relaxing.

Along with product 11 and the vertically propelling of material band 18,18B, the band 18b on top is that anti-Zhe returns between the adjacent product, and provides one generally to have "T"-shaped overall variation portion.Under the effect of roller 49, advance, pressure is affacted on product 11 and the top vertical material band 18B, bonding with tenaculum 18B and product 11 end faces.The band 18B in change section combine with the viscosity of product 11 limit portions owing to product 11 by export orientation bar 50(and counterpart thereof) between be easy to the realization, this pilot bar 50 is installed inwardly with respect to inlet guide bar 43, is pointed to in-to-in power to the sidepiece of product 11 and apply one.From inlet guide bar 43 to also being provided with the horizontally-guided bar 47 of convergent inwardly between the export orientation bar 50, with combining of the sort of change section of further support and product sidepiece.

Product is with vertically material band 18,18b promptly are sent on the spirally circumvolution multiple package position 14 for example shown in Figure 1 after frame 38 is come out.In the spiral circumvolution process of this kind, under the effect of the power that the helical coil tape wrap that trails is applied, the slide relative or the rolling of adjacent product have reduced, and, usually make above-mentioned slip or roll and eliminate basically owing to having utilized overall variation portion in vertical strip of wrapping material to reduce contacting between product and product.

As mentioned above, this kind equipment is specially adapted to the goods of container dimensions than the right cylindrical complexity, for example narrow mouth container or similar products.As shown in Figure 5, the bottle of 3 * 3 arrays can be packed with the vertical strip of wrapping material 18A and the 18 and one intermediary layer 18b of upper and lower, this intermediary layer has the 18E of overall variation portion, when spiral circumvolution packing esting and inclination takes place to eliminate these bottles.
