A special now most preferred embodiment that describes foundation method and apparatus of the present invention with reference to attached sketch in detail.These accompanying drawings only show understands the indispensable parts of the present invention.
Fig. 1 is from the top view with the major part of the device of method Display Realization the inventive method of simplifying.
Fig. 2 is the device in the displayed map 1 from the side.
Fig. 3 A to E roughly shows length by length according to the method with thin film encapsulation object spare of the present invention.
Foundation illustrated in figures 1 and 2 device of the present invention is used for that thin film encapsulation 1 is added on packing and holds 2.Packing container 2 is made by the wrapping machine (not shown), and this wrapping machine is connected in apparatus of the present invention via first load-transfer device 3.First load-transfer device 3 is driven by an actuating device (not shown), running on carrying roller 4, and the supporting of carrying roller 4 can freely be rotated it on the center shaft of level.The prolongation of first load-transfer device 3 and it slightly above, conveyer 5 is arranged, this conveyer comprises that two are each positioned at the parts that packing container is given passage one side, these two parts all have a cycloconveyor belt 7 that driver 6 is housed.Load-transfer device 7 turns round on the carrying roller 8 that freely rotates around vertical central axis, and is positioned at the both sides of carrying roller 4.The other end of conveyer 5 has carrying roller 9, and the latter links to each other with the actuating device of being made up of (for example) electrical motor 10.They drive two load-transfer devices 7 to two opposite direction runnings, and in other words, the live part of load-transfer device faces with each other, and in Fig. 1 and Fig. 2, moves from left to right.Between the carrying roller 9 slightly below, a carrying roller 11 is arranged, be used for second load-transfer device 12.The last live part of this load-transfer device 12 enters the pyrocondensation stove 63 of an ordinary hot Air type or infra red type.
Be equipped with between two load-transfer devices 7 of driver of conveyer 5, soldering and sealing and breakaway-element 14 are arranged, it comprises two soldering and sealing and separates jaw 15,16 that they are positioned at the above and below of conveyer 5 accordingly.Two jaws 15,16 all have the driving surface of length direction and toward each other, extend in the horizontal direction perpendicular to conveyer 5.A jaw (for example end jaw 15) has an available electrically heated sword 17, is positioned at the central authorities of driving surface.The driving surface of jaw 16 on the other side is flat basically, and there is an elastic region at its middle part, and it can be by flexible material (rubber) formation that is suitable for cutting edge 17 cooperations of heating.The driving surface of jaw 15 is equipped with the but interior conduit of fluid such as cold water of cooling in addition.The structure of this jaw is common, is commonly used in the known means of heat-shrinkable film wrapping machine, so this respect just is not described in detail or illustrates.
Soldering and sealing with separate jaw 16 and be positioned at conveyer 5 tops, by rack support, and can move back and forth in vertical direction along guide rail 18.This jaw drives with common mode, for example uses a cam mechanism or by means of a steam cylinder piston device.Drive the intermittence of the driving of jaw 16 and conveyer 5 synchronously, guaranteeing that jaw 16 only contact with regular jaw 15 in conveyer 5 left alone without help having a rest, and assurance jaw 16 is in one and makes it can be in load-transfer device 7 and the position that be moved freely by the gap between the packing container 2 of conveyer 5 transmission.
During apparatus of the present invention running, packing container 2 is sent to along the live part of load-transfer device 3 tops at regular intervals.Between two load-transfer devices 7 of conveyer 5, packing container is engaged double-type driver 6 clampings one by one and and transport.Driver is designed to the short angle of stretching out from load-transfer device 7, and they clamp the relative base angle of packing container, makes it off and on, in Fig. 1 and Fig. 2, moves from left to right.
When packing container 2 during near soldering and sealing and breakaway-element 14 and contiguous their reel film 19, jaw 15,16 is in open position (Fig. 3 A).Packing container 2 continues forward, contacts with film strip 19, and the latter unclamps from film roll 20, and the supporting of reel 20 can freely be rotated it.Constitute film feed element 21 cylinders 22,23 each other constant engagement and and waste material band 24 constant engagement between them, retracted by waste material reel 25 when so just preventing that the waste material band is before film is pulled to.The length of sealing the required film of packing container 2 only gets around from film roll 20.
When packing container between two open jaws 15,16 by the time, moveable jaws begins to move down, and this means that film strip 19 further gets around from reel 20.The film strip slides to the driving surface of moveable jaws 16, until two jaw contacts (Fig. 3 C).In this position, conveyer 5 packing container 2 that shut down is then surrounded by film annular cover fully, and the end of this film cover is just between the driving surface of jaw 15,16.The sword 17 of regular jaw 15 is heated to and remains on required temperature, interconnect function by cooresponding elastic part on jaw circumferential surface and the moveable jaws, the partial melting that pastes mutually each other on the one side film strip also merges, and is used to form the part of sealing on the other hand on the film strip and separates with the membraneous material that stays.The design of this jaw makes around the band of material of packing container to be welded together, thereby obtains thin film encapsulation 1, and film strip 19 and waste material band 24 are welded together in this same operation, and last, between welding point, thin film encapsulation separates with cylinder material.
When operation finishes, soldering and sealing with separate jaw 15,16 and back move again, jaw 16 is got back to its upper stationary position (Fig. 3 D).Simultaneously, 21 startings of film material tape feed element, make waste material band and the film strip that is attached thereto move a segment distance forward, thereby the place slightly down that the material plug 27 that produces during soldering and sealing is moved the driving surface of lower jaw 15 to so just is unlikely influence soldering and sealing operation subsequently.This is necessary, because the soldering and sealing joint that forms previously forms a local shape fitfull reinforcement on strip, can not carry out another time soldering and sealing herein.By means of above-mentioned photoemissive element 26(Fig. 2), can guarantee that film strip 19 is drawn forward a position at the same time, so that make its literal and decorative pattern be in correct position, with the shape alignment of the packing container of back.Because the strip feed element all engages in whole procedure with strip, the position of strip can not change by accident, so said process can carry out accurately.So far, this device is got ready for the thin film encapsulation of next packing container, conveyer 5 entry into service again, and push forward packing container (Fig. 3 E and 3A), so this operating process repeats, till the bale capacity of requirement all possesses means of heat-shrinkable film and seals.
For the distortion on the material plug 27 of the up-to-date generation that reduces waste material band 24, apparatus of the present invention also are equipped with anchor clamps 29, with so that waste material band 24 keeps stable when object is sent to forward.Fixing device 29 comprises that a folder refers to 28, and it presses to regular jaw 15 to the waste material band after the waste material band is presented forward.This folder refers to and can move around, when it is in withdrawal or open position, before feed element 21 can freely pull to waste material band 24.When folder refers to that when in the closed position, the waste material band moves backward and is obstructed because waste material band 24 be sandwiched in folder refer to 28 and regular jaw between up-to-date generation the material plug place or be clipped in the tight back of this joint.In this way, when the soldering and sealing joint still was in hot state, distortion just was unlikely and reaches this joint because reel marches forward to the strip that causes, has significantly reduced the danger of strip in the connector area retardance thus.This device is particularly useful when high-speed production.
After packing container 2 is closed in the thin film encapsulation 1, be sent to second load-transfer device 12(Fig. 1,2), this load-transfer device will have the packing container of sealing with suitable speed and import pyrocondensation stove 13.There, means of heat-shrinkable film is heated to the temperature that pyrocondensation takes place and is close on the profile of packing container.So far, the packing container that band is sealed has been made, and it can continue to move, and for example further is packaged in the concentrated container to transfer out.
Above-mentioned foundation method and apparatus of the present invention is good through facts have proved function, it can with per hour nearly 8000 speed seal packing container.Higher if desired speed, can be soldering and sealing and breakaway-element 14, the deflector roll of film material tape feed element 21 and film strip is connected on the reciprocal support, the latter coordinates with conveyer 5 in forced stroke and backhaul, make the conveyer 5 can be by continuous drive rather than drive off and on, its result per hour can obtain the manufacturing speed of 12000 packings nearly in theory.
