Description of drawings
Feature of the present invention will following with reference to accompanying drawing to some preferably but obtain in the description of not exclusive embodiment the explanation, wherein:
Fig. 1 is the lateral plan that adopts the whole device that the blister-pack article of plastic material use according to method proposed by the invention;
Figure 1A represents the part of the film of plastic material;
The amplification of K diagram in Figure 1B presentation graphs 1;
Fig. 2 is the planar view of device proposed by the invention;
Fig. 3 is the corresponding top view of plastic film tape in the article packing process;
Fig. 4 is the partial side view of another embodiment of device proposed by the invention.
The specific embodiment
With reference to above accompanying drawing, Reference numeral 1 expression is used for the protective film with plastic material, is preferably transparent for example glass paper, to article 2 device that coats such as book, newspaper, magazine for example.
Article 2 to be coated are supplied to device 1 successively by travel line 3, and this travel line 3 is equipped with suitable driver train 4 by known methods.
Device 1 is included in the load-transfer device 5 of running continuously of direction shown in the arrow A.
Plastic film tape 6 also is drawn out of from the entrance area of article 2 to be packaged thus by continuous supply on load-transfer device 5.Plastic film tape 6 launches from bobbin 16.
Enter the upstream region of load-transfer device 5 at article to be packaged 2, plastic film tape 6 applies the suitable adhesive that is suitably heated by station C at station C place.
Station C for example be arranged in with 6 corresponding zone, vertical path, extend between suitable deflection roller 7 in described vertical path with 6.
Be provided with the first adhesives applying mechanism 8 and the second adhesives applying mechanism 9 at station C, the nozzle of known type is for example arranged.
The purpose of the first adhesives applying mechanism 8 is that the longitudinal edge along plastic film tape 6 applies strip of glue 18; The purpose of the second adhesives applying mechanism 9 be with plastic film tape 6 traversed bies apply the isolated regularly adhesive area 19 of a series of quilts (referring to Figure 1A).
Strip of glue 18 and horizontal adhesive area 19 preferably are applied on the same side of plastic film tape 6, especially are applied to plastic film tape 6 and are diverted package 2 in-to-ins one side.
The longitudinal edge contact fold mechanism 10 of plastic film tape 6 its objective is with barrel shape plastic film tape 6 is coated around the article 2 to be packaged that are sent to successively on the load-transfer device 5.
The edge of fold mechanism 10 guiding plastic film tapes 6 passes the top of article 2 also basically along the middle longitudinal axis of load-transfer device 5 overlapping (especially referring to Fig. 2).
The direction A that moves forward at load-transfer device 5, be provided with rotation in the downstream of fold mechanism 10 and add pressure zone 11, its objective is basically in the zone that covers by vertical strip of glue 18 overlapping edge effect, so that the joint at edge becomes firm to plastic film tape 6.
Rotation adds the position of pressure zone 11 and can vertically regulate by suitable actuating mechanism.
Cutting mechanism 12 is positioned at the downstream that rotation adds pressure zone 11, is arranged in and the corresponding zone of load-transfer device 5 formed rings that is limited by a series of deflecting wheel 14.
The purpose of cutting mechanism 12 be with corresponding zone, the bonding part of horizontal adhesive area 19 in transverse cuts plastic film tape 6, to obtain the individual packaging spare of article 2.
In this application, cutting mechanism 12 comprises a pair of counterrotating roller 13A, the 13B that lays respectively at top and bottom, is provided with suitable cutting element T on their circumferential surface.
Cutting element T comprises blade 50, and this blade 50 is carried diametrically by upper wheel 13A and between two pressurizing member 60A, 60B, its objective is by two in the nip 19 lateral part 19A, 19B side by side.By described part 19A, 19B branch being opened by blade 50 cutting areas 19.
Therefore,, apply strip of glue 18 along the longitudinal edge of plastic film tape 6, and on plastic film tape 6, apply by isolated horizontal adhesive area 19 regularly at station C according to the method for connection with wrapping of piece 2.
Adhesives can be in a continuous manner, point send mode or uses needed other suitable mode to be applied in.
Fig. 4 represents the different embodiments of described device, wherein the first adhesives applying mechanism 8 has a pair of counterrotating wheel 15, described wheel 15 contact plastic film tapes 6 also pass through suitable adhesive case 17 and supply with, thereby apply continuous strip of glue 18 along the longitudinal edge of plastic film tape 6.
The plastic film tape 6 that is applied with adhesives is thereon supplied to load-transfer device 5 continuously, and above load-transfer device 5, article 2 to be packaged are transmitted successively in each position that laterally limits between the adhesive area 19.
Subsequently, the edge of fold mechanism 10 folding plastic film bands 6 to be forming tube around the material to be packaged 2 that is sent to successively on the load-transfer device 5, thereby with the imbricate of plastic film tape 6, makes the opposed edges of vertical strip of glue 18 contact plastic film tapes 6.
Then, rotation adds pressure zone 11 and acts on the overlapping edge of plastic film tape 6 basically in the zone with vertical strip of glue 18, thereby makes vertical joint at described edge become firm.
Be coated on counterrotating roller 13A, the 13B that article 2 plastic film tape 6 on every side arrives cutting mechanisms 12 with barrel shape, because the effect of little pressurizing member 60A, 60B, cutting mechanism 12 make the joint of the part with horizontal adhesive area 19 become firm and pass through cutting element T transverse cuts band 6.
It should be noted that by blade 50 to be the centre in the zone 19 between part 19A, 19B (referring to Fig. 3) more accurately, transverse cuts plastic film tape 6 along by horizontal adhesive area 19 bonded assembly parts.
Therefore, the method that is proposed has realized utilizing in mode effectively and efficiently the purpose of the blister-pack article of plastic material, and especially it has reduced the time length of wrapping cycle, and has improved capacity rating significantly thus.
Resulting package is shown as in Fig. 3 still and partly is bonded on the plastic tape, this package comprises article for example magazine, book, the newspaper etc. in the thin slice 6 that is covered by the plastic material with end 19A, 19B, and described end 19A, 19B are sealed by the strip of glue between the upper and lower part of described thin slice.By strip of glue 18 longitudinal edge of described thin slice is bonded with each other.
Especially, obtain this result and be because: be applied to suitable adhesive on the plastic sheeting by adopting at suitable station, realized being coated on vertical joint at the edge of article plastic sheeting on every side with barrel shape, and the horizontal joint of the identical tubular plastic sheeting between two adjacent article.
In other words, the scheme that is proposed has overcome the existing technological deficiency of known devices, wherein realized vertically and laterally engaging of plastic sheeting edge, because it has saved all required heating-welding mechanisms of sealed plastic band well-known to those skilled in the art and has eliminated associated all problems by heating-welding.
It should also be noted that by simple, reliable and general-duty device and obtain The above results.
Should be realized that, with reference to accompanying drawing only to have but and unrestriced example proposed invention is described.Therefore, it is evident that in reaching following protection domain of asking such technical solution of the present invention as described above and can make any change and modification the present invention.
