Description

Blister package manufacturing process and welding gear thereof

The present invention relates in continuous handling or continuous in-time operation, make to have and gives the setting shape and the bubble type packing that holds connection with wrapping of piece and object of clear and definite volume or the method for similar packing are arranged.At least use the metallic paper or the film roll of two kinds of different materials in the method, preferably extract out from the axle volume as formalize basis or bottom thin film and cover film.Also relate to a kind of equipment or instrument,, the setting film that is pressed into shape deeply that holds goods and one cover film of adhesion with it will be arranged, be sealed into bubble type packing by heating and pressurization.

Blister package day by day increases in the use aspect the medicine of tablet form and pill form etc., therefore now has been difficult to see the tablet with little tube packaging.Yet blister package also is used for the object of other wide spectrums, such as household wares, and food, cake, business is in office and handicraft or the like scope.Can see tubule at present, medicine bottle, instrument, workpiece be such as iron nail, drawing pin, folder, the bubble type container of condiment or the like.All these details can only belong to character for example at this, also will enlarge day by day but not shrink because situation is a range of use.

Nowadays, in the orthodox method of this packing, manufacturing is held the setting film roll material setting of article cavity to be packaged, when essential, heating/heating and hold article afterboarding to be packaged.Two kinds of cylinder materials are by being tightly connected.To pack from the film rolling width of cloth and downcut, collect film pin material then.

The legacy equipment or the instrument that are used for this purpose have pair of plates or roller-type tools section, by both relative actions, accept film between the two, form packing and carry out sealing process.Being preferably in following is one first tool part, at least one depression is arranged above it, put setting holding on the film to be packaged and treat freezing object at least one be pressed into the shape bubble deeply, one second tool part preferably goes up tool part, pressurize and heat in the surface that corrugation shape is arranged.

Because raw material and the energy are day by day deficient, have especially noted reusing of packing, once the someone disclosed (DE-OS-3,110, No. 254) in blister package is produced, especially in pharmacy industry, and a large amount of waste recovery that the charging error is caused.Owing to relate to the problem that traditional aluminium is separated with the PVC composite material, and for avoiding the generation of problem, the composite material of PVC and aluminium must be supplied with crusher pulverizes, doping in the pulverized particles of aluminium and PVC, especially add the plastic powder particle raw material, special in molding, job operations such as injection moulding or extrusion forming form the new plastic product.The material of making need be engaged in waste disposal, and can be used for the plastic molded construction of polyurethane foam module and the aquaseal in the building industry, and as the spike of making wood wool board (chipboard).All these relate to the use of the composite material of stock production object, and the quality of its raw material is unimportant, on the contrary, use the packing material of low-quality and interpolation material that final products are not had negative consequence yet.Therefore, need not consider such as aluminium and for example high value and the high price of the woof of plastics etc. the PVC.In fact, problem results from film or the metallic paper reel material made from different materials, as be the medicine blister package, generally make the setting film with PVC, aluminium is made coverlay or paper tinsel, though may make the setting film and make another film with other plastics at many other fields with paper material, entire area welding or bonding, thus these different materials lump together when packaging process finishes.The result, in the past, when the blister package production process finishes, the waste material bar of jointing material or die-cut pin material account for 10 to 20% of packaging film reel, not doing production and processing again uses, on the contrary, compare with the materials recycling product that the error of will feeding in the pharmacy industry produces, being considered to useless waste material in the past must be handled subsequently.

Main purpose of the present invention is the method and apparatus that proposes a kind of known type, can satisfy requirement on environmental protection aspect the waste material recirculation.

Specific purposes of the present invention are to make waste material make recirculation usefulness in the blister package process, and the raw material of costliness is reclaimed respectively.

Another purpose of the present invention is to propose a kind of method, realizes the sizable saving of material cost, and proposes a kind of equipment that is fit to this method.

In the method for the type of above-outlined, why these purposes obtain, and are that recirculation will formalize and the waste material of cover film is collected respectively in order to do because welding is only carried out will pack the region surface of downcutting from material.As use the said equipment, why the present invention can reach above-mentioned purpose, be in when welding, in two tools sections at least one, the edge of its running surface or action face, consistent with the border (edge) of blister package.

Therefore, when solving set problem, method and apparatus of the present invention provides a kind of possibility, exactly when making blister package, with limited technical fee " generation " waste material, can directly supply with the raw material of sorting to process recycling.Therefore this packing method is favourable to ecology, saves the energy, and the pin material of not forgetting the film roll material simultaneously may reach 10 to 20% when producing this blister package, and assorting room just can use for recirculation subsequently.When blister package has tangible rising tendency, show that this is important paces aspect the raw material that day by day lacks in the promotion saving.In addition, owing to can keep low-down pin material cost of further processing, just may obtain the actv. cost savings.Tool construction of the present invention can be used a kind of plain mode, and it is bonding with the setting film only will to make packaged surface, and all keeps separating with whole remaining activity membrane portions.The general construction of this instrument is also uncomplicated, can add on existing installation easily and install, also can be with the corresponding transformation of existing instrument, for example by milling or corrosion processing etc.At the cutting of equipment and manufacturing line or the Die cutting tool on the die-cut station, shape is consistent with packing, thereby can on the film bar of advancing, cut packing, accurately consistent with action face or running surface, thereby on the avris and each packing between the pin material of excision be continuously band shape, can distinguish further and process.

For careful about goods to be packaged as far as possible, especially to the goods of temperature-sensitive and/or pressure-sensitive material, soft capsule etc. for example, in the further developing of method of the present invention, when welding, can only hold on the mating surfaces that is pressed into the shape film deeply of goods to be packaged, make film bear the effect of essential pressure of welding and heat.

In the special proper arrangement of soldering outfit,, then action face can be limited to the size on blister package surface if blister package has flat coverlay.Preferably make the action face of tool part on second partly more outstanding than remaining surface.This point is being transformed or during additional device, on the film tape width that is equivalent to substantially be called in the past on the welded plate, can be with the surface milling or the corrosion easily of existing tool part, thus packaged surface that only will be to be made gives over to action face.

In welding process, for anti-pressurization and heating have passive influence to the preparation to be packaged that is pressed in the shape deeply or put into formed film, if be medicine, for example soft capsule etc. is then especially harmful, so the action face of last tool part has suitable structure, have and do not heat the position, its number, size and location are consistent with depression on the following tool part.

Other purposes of the present invention just can check on from following explanation and claims and accompanying drawing, and desirable embodiment of the present invention and principle thereof are shown in the accompanying drawing letter, now think the best form of implementation of this scheme for having considered.Be familiar with that this area person can just implement same principle of the present invention or doctrine of equivalents adopts other schemes, can carry out structural variation on demand, and do not break away from the scope that the present invention and right thereof will books.Accompanying drawing is as follows:

Fig. 1 shows the side-looking of blister package equipment principle;

Fig. 2 is soldering outfit side-looking disconnected from each other;

Fig. 3 is equivalent to Fig. 2 for last tool part, the looking up of line III-III.

The blister package equipment that Fig. 1 shows is only represented its principle and non-details form, wherein has 14, one cuttings of 13, one welding posts of a forming station or die-cut station 15 and a pin material to collect station 16, is arranged on the base or basis 10 of a machine; With the coverlays 12 from storing 111 a setting film 11 that are commonly referred to as counterdie or basement membrane of extracting out and extracting out, the blister package of production medicine (tablet, pill etc.) from storage axle 121; On forming station 13, the film 11 that will formalize is pressed deeply, forms the bubble 112(Fig. 2 that holds tablet 3); Welding post 14 is in heating and add and depress, and will formalize film 1 and coverlay 12 weld; Cutting work station 15 is downcut the blister package of finishing from continuous reel film; Collect station 16 the pin material of collecting axle 161 collection formed films 11 is arranged; Axle 162 is collected the pin material of coverlay 12.Two kinds of films that this pin material is collected station 16 are collection structures respectively, with to have only collecting of field to mix the pin material earlier opposite, the soldering outfit special construction in Fig. 2 and 3 are arranged.Certainly do not need balled scrap agglomeratingly, and one first reprocessing process is supplied with in obviously desirable pin material sorting respectively, for example the process that is made of chopping and/or crushing process.

A soldering outfit 2 forms the main portion of welding post 14, as shown in Figure 2, a following tool part 21 is arranged, and form is a receiving plate, goes up tool part 22 for one, and form is a welding drift.Two tool part 21,22 of diagram are in does not work, and promptly leaves the position mutually.Two film bars have setting film 11, and bubble 112 forms in the above, and goods to be packaged have been put into wherein, are tablet in this example, and coverlay 12 passes through between two tool part by timing or cycle mode.On graphic position, bubble 112 is in the top of the depression 211 that forms on the receiving plate 21.In the time of on this position, welding process just can begin, at this moment move on the direction of receiving plate 21 by arrow A, thereby cave in 211 and receiving plate 21 bubble is held, receiving plate does not heat, if needed can it is freezing, the bottom side of preliminary contact setting film 11.Be heated to the welding drift 22 that requires temperature be generally static, but some the device in also can move down by the direction of arrow B.Because this relatively moves, the surface of setting film 11 is crushed on the coverlay 12.The adhesive phase of making bonding usefulness is established in the bottom side of coverlay 12, because the pressure that produces between receiving plate 21 and the welding drift 22, and because the heat that drift 22 transmits, adhesive phase is bonding with setting film 11.

Looking up from Fig. 3 in conjunction with the side-looking among Fig. 2, as seen welded drift 22 bossed action face 221, its maximum surface is accurately consistent with packaged surface to be made, or less, to avoid die-cut pin material and die-cut waste material and material there be any involving, and guarantee to do to cut off simply rapidly.As simple giving an example, as shown, packing has three dark tablet bubbles that are pressed into shape.The making of the action face relative with remainder is by milling on welded plate.But also available any other suitable method for making produces this action face.Corresponding mode is pressed in the setting of the Die cutting tool of die-cut station 15, thereby packing can be cut out with respect to action face, output in the slave unit 1, and setting film 11 and coverlay 12 as shown in Figure 3, are sent along trapezoidal lattice.Just weld on the total surface of drift 22, formation is with respect to the depression 222 of action face 221, action face can be improved welding pressure, and be provided with this as among watt spinulose tree fern network 223(figure of known technology only shown in the upper left quarter, but the whole action face of actual covering), have and do not heat position 224, corresponding with the depression 211 of following tool part 21.In the instrument of slab structure, mode as shown, a watt spinulose tree fern network forms little pyramid, or the jut of butt shape, though therefore film has any unevenness or protrusion, welding pressure is even, thereby obtains flawless packing.If but use roller or drum barrel type instrument, its surface is provided with bossed cross line traditionally, to obtain uniform pressurized conditions.

The punching instrument of plate shape soldering outfit and respective design can be done continuous timing production operation as shown.If but require to do the continuous process of not timing, and then can adopt the said structure of roller or drum barrel form instrument, as for doing regularly running, instrument according to its position relative to each other, is made accuracy control.

With the obtainable advantage of the present invention, be that the film pin material boundary of sorting is clearly demarcated, can be simply and supply with to the recirculation operation that matches with various certain material compositions rapidly, thus can be made into very pure high-quality recycled product. Simultaneously, because watt spinulose tree fern line can be with the size of concrete packing, at least with respect to its edge area, arrowhead just can reduce corrugation line manufacturing expense. Owing to process a large amount of Different Package sizes, just need prepare proper implements, in installation or manufacturing expense with the equipment of instrument, instrument accounts for very important status. And the present invention need not process film waste fully, and especially in the drug packages industry, pin material amount is quite big, thereby ecology has been made significant contribution, has proposed the design of useful environment in packing technique.

The present invention is not limited with the specific branch of packing technique certainly, and can successfully be used for having the pin material of mixing and the film of the various different materials types that sorting throws into question, the processing of metal forming or material layer, for example, the present invention is applicable to dairy husbandry, especially be applicable in the equipment of filling, in the deep drawing molding plastic containers, fill emulsion, cream, sour milk, curdled milk, blancmange etc., the plastics of making bowl in the equipment are supplied with continuous reel band, utilize forming punch or vacuum under heating, deep-draw become to increase and quality device closely, and is different from the method for filling of the difference bowl of common usefulness, the carrying out of perfusion and sealing used the continuous aluminium foil of extracting out from spool at welding post. In the operation in the past, the waste material die cutting of single bowl must shred, and makes then particle and processes. The present invention also can realize plastic material and metal forming (aluminium) are cleared up respectively, does the recirculation that economizes in raw materials.
