Description

A kind of packing device that is used to make package

Technical field

The present invention relates to a kind of packing device that is used to make package.

Background technology

The present invention uses on making the external packing machine of cigarette case to have this machine of introducing below the advantage one and only proposes with form for example, but is suitable for its advantage of performance on any packaging machine of the overlapping portion heating of the packing that will have adhesives therebetween equally.

Outside on the packaging machine; the finished product packing spare that packaging machine is produced coats with a normally transparent heat seal mateiral; this material forms a tubular parcel in the package folded around, and the bottom that surpasses package is stretched in the bottom of parcel, and forms the protectiveness external packing in the package bottom fold.

On the external packing machine of the above-mentioned type, the bottom that folds usually makes it fixing with being installed in the apparatus for heat sealing that transports on one or more heat seal station on the path along package.When package stopped on station, apparatus for heat sealing just carried out heated sealant to it.

On one of the above-mentioned type known external packing machine, because will be with the folded end of less time these outer packagings of heat seal, apparatus for heat sealing must be mentioned so high temperature, so that since any former thereby when the operation of a machine is slowed down, will damage this housing material.

Movably apparatus for heat sealing is installed in a trial of attempting to overcome above-mentioned shortcoming exactly on machine, promptly this device can together move with package along certain part of machine.Keep one long period to contact thus, or make the time long at least to apparatus for heat sealing might be moved under lower temperature with package.

The utility model content

The purpose of this invention is to provide a kind of packing device that overcomes the preceding defective of being mentioned that is designed for.

According to the present invention, provide a kind of packing device that is used to make package.This device comprises: the bearing that at least one moves step by step along a given path, and extend by a series of fixedly station in this path, and bearing stops on station; At least one heater element, it and aforementioned bearing be together operation on aforesaid paths; It is characterized in that aforementioned heater element is a passive element that comprises a thermal accumulator; In (better) at least some aforementioned fixation stations, induction installation is installed, to supply heat to aforementioned thermal accumulator in a fixed position.

Description of drawings

Shown in Figure 1 is the planar view of a part according to a preferred embodiment of the present invention, wherein for the purpose of understanding some parts is removed;

Shown in Figure 2 is the front elevation of the details of Fig. 1;

Fig. 3 and shown in Figure 4 being respectively along the radial section figure of III-III among Fig. 1 and IV-IV line.

The specific embodiment

Wrapped in Cellophane machine of numeral 1 expression among Fig. 1, it comprises that is used to form an external packing device 2 that wraps in the transparent material packaging element 3 outside the cigarette case 4.Device 2 comprises that is transmitted a wheel 5, and it supports between two walls 7 of frame 6 and by frame 6, thereby can wind the axis 8 substep left-hand revolutions (in Fig. 2) perpendicular to wall 7.Wheel 5 has shown some radially bearings 9 on the circumference that axis 8 equidistantly distributes, bearing opens wide at its relative axial end, each bearing all receives a package 4, the longitudinal axis 10 of package is parallel with axis 8, and simultaneously two diapires 11 of packaging element 3 and axis 8 are vertical and be positioned at opposite axle head towards the bearing 9 of separately wall 7.

When wheel 5 in each steps of axis 8 rotation, bearing 9 march forward to two; The identical distance of distance that the bearing that adjoins is 9, and when each EOS, each bearing 9 all rest on fixedly among the station 9a.

Each packaging element 3 is all outside folding along package 4 with the one sheet of packing material (not shown) with the known method (not shown) in advance, to form a tubular packing (not shown), the end separately that two opposed end (not shown) of this tubular packing stretch out package 4, and (not shown) is folding in a known manner, form four contact pin (not shown), when package 4 by wheel 5 when forwarding, one of contact pin is folded in and becomes squarely on another, and is fixed with thermosealed method.

For reaching this purpose, for each bearing 9, wheel 5 provides a pair of compacting member 12, they can move along two opposite senses, toward or away from the operating position that contacts with the outside face of separately wall 11, each compacting member comprises a square rocker arm 13, it separately perpendicular to the pin 14 of axis 8 on around the rotation of its center, the compacting member is installed between the ear of the corresponding fork 15 of projection on the corresponding axial end surface of trailing wheel 5.Rocker arm 13 comprises two

arms

17 and 18 that extend along pin 14 both sides, and arm 17 extends in the cavity 19 that axially connects, and cavity passes wheel 5 and radially forms in bearing 9, and is separated by the bottom surface 20 of wall 21 with bearing 9.On the other hand, arm 18 extends in the outside on separately surface 16, and integrally at its free end a heater element 22 towards the axle head separately of separately bearing 9 is installed.Each heater element 22 comprises a closing plate 23, it in use, when corresponding compacting member 12 was positioned at its operating position, its position will contact with the outside face of corresponding wall 11; Each heater element 22 also comprises a regenerative block 24 that contacts with surface towards the plate 23 of corresponding wall 7.

As shown in Fig. 3 and Fig. 4, the arm 17 of each compacting member 12 all passes through to insert as more clearly.Pipe link 25 is connected with the arm 17 of another compacting member.The core of pipe link is hinged on the free end of take-off lever 26 of linear actuators 27.This actuator 27 radially is positioned at the inside of corresponding cavity 19, and being used to make pipe link is radially outwards to move to the effect of the spring 28 of Hangzhoupro between pipe link 25 and wall 21.

Except that wheel 5, packing device 2 also comprises a heating arrangement 29, and the latter itself comprises a series of double-type inductive heating elements 30 again; Each heater element 30 1 of each centering has a screw actuator one usually and is supported on station 9a place separately on the frame 6 respectively, its surface of position to and adjoin the regenerative block 24 that connects on the compacting member 12 that is fixed on the ga station.More clearly shown in Fig. 3 and Fig. 4, on one side towards wheel 5, each wall 7 is determined by surface 31, surface 31 presents a flute profile part 32, flute profile part 32 is farther apart from wheel 5 specific surfaces 31, and in the extension of the path of compacting member 12 part, on this path, the off-position after the compacting member remains on and is raised.Surface 31 and flute profile part 32 have some cavitys 33, and each cavity all is positioned at a t position 9a, and each cavity all is equipped with the cup-shaped housing 34 that is used for corresponding heater element 30.

Describe as seen from fwd, the operation of packing device 2 is clearly.Yet be noted that heater element 30 is the fixed type heater elements that do not need any power source electricity play or analogue on the one hand; Simultaneously, on the other hand, compacting member 12 is with package 4 when together mobile, the one period long time cycle and can adopt so relatively low operating temperature of can cooperating with package 4, so that will never damage packaging element 3.

Though device 2 shaped portions as Wrapped in Cellophane machine 1 are described, it also can be used for the machine of other type naturally.For example, wheel 5 can be a folding wheel or a drying wheel on the wrapping machine, and is wherein different with heat seal, and compacting member 12 only is used to guarantee to make the gluing of packing partly to be in the tram and makes glue drying between each several part.

At last, device 2 also can be foregoing like that at the enterprising line operate of sheet of packing meterial that contains metallic material (being paper tinsel or analogue) to small part, is used for the superimposed part of these material piece of heat seal.
