The present invention relates to a sealing apparatus for cocurrent flow.

Generally, food bottles (vessels) such as milk, juice, yogurt, etc., adhere the encapsulation body (cap) in order to detect contamination around the bottle mouth. In other words, after filling the glass or synthetic resin bottle with the contents, an oil-conical cylindrical (envelope cup-like) encapsulation made of a heat-shrinkable plastic film (thin film) is placed in the bottle and then heated and shrunk. It is tightly sealed and is not contaminated with food.

However, as described above, the encapsulated body is not only an oil well cone, but also a very thin thin one that is suitable for mass production or mass consumption. Therefore, their encapsulations were extremely poor in workability and difficult to automate. Particularly, after the encapsulation is manufactured, it is made of one rod-shaped polymer, which is dense on a plurality of equiaxes, so that it is easy to handle when it is carried out, but on the contrary, when the encapsulation is removed from the polymer one by one On the contrary, there was a problem in that it was very difficult to separate the encapsulation from the polymer one by one. In other words, the encapsulated body is so thin that the weight of the encapsulated body is in close contact, and thus, when it is taken out, it is difficult to make a vacuum between the close encapsulated bodies, and it is difficult to reliably separate out one by one.

SUMMARY OF THE INVENTION The present invention has been made in view of these circumstances and one of its main features is that the encapsulating encapsulation is deformed with respect to another encapsulation in close contact with it, thereby forming a gap in which air is introduced to separate only between the apiary encapsulation and It is possible to extract only one body.

Other specific structural features and advantages of the present invention will become apparent from the following description.

In the present invention, the charging container refers to a vertical cylindrical body having a smooth inner surface in which the polymer (or aggregate) of the encapsulated body is slid up and inserted downward of the top of each encapsulated body. As a result, there are steel bars, so that they do not fall downward. In addition, this steel bar is made to be excluded from the portion corresponding to the contact direction of the extraction arm protrusion, which will be described later, that is, the inner circumferential portion, and has a function of deforming the encapsulation body as a whole. In addition, the steel bar may be a plurality of iron groups which are discontinuous. Of course, the slope of these barbed wire or ironware should be smooth.

In the present invention, the withdrawal arm means an arm having protrusions for sequentially removing the encapsulation body one by one from the lower opening of the electric charging container. In the present invention, at least two arms are disposed to face each other. Arms other than two include three or four at equal angle intervals. It is necessary for these protrusions to increase the friction with respect to the inner surface of a sealing body, and it is preferable to coat a rubber cap on the surface specifically ,. In addition, these protrusions need not only simple contact with the inner surface thereof but also elastic contact in drawing the encapsulated body. Specific examples of the elastic means include elasticity obtained by the rubber cap or tube.

The feeding mechanism 4 of the encapsulated body to be covered with the milk container M portion and the heating (shrinkage) tunnel 69 as the sealing mechanism 5 to seal the encapsulated body S, respectively, were provided.

The encapsulation body extracting mechanism (2) has a charging container (6) for sliding the polymer (T) of the encapsulating body upwardly and projections (7) (8) for extracting the encapsulating body one by one from the lower opening of the charging body. The leading arms 9 and 10 and the protrusions 7 and 8 enter downwardly into the encapsulation at the bottom of the polymer T to make a tight contact with the inner side thereof and to maintain its contact state to escape coaxially downward. It is mainly comprised by the movement control means 11 which moves the said extraction arm 9 and 10. As shown in FIG.

The charging cylinder 6 is mainly composed of an upper cylindrical portion 12 and a lower cylindrical portion 13 and a supporting cylindrical portion 14 of the lower cylindrical portion, which form a smooth sliding inner surface, and the lower cylindrical portion 13 is formed of an upper cylindrical portion ( 12) and the inner circumferential edge of the lower opening 12, and the lower inner circumferential edge 15, except for the portions 16 and 17 corresponding to the impact direction of the projections 7 and 8, which will be described later. (19) was laid. Further, (20), (21), (22), and (23) are partition bars extending downward from the lower opening cross section of the lower cylinder portion 13.

The lead arm 9 has an arm portion 24 and a protrusion 7 at its distal end, and the arm portion is formed by slightly bending the solid plate at the X portion, and the upper portion including the protrusion 7 looks outward. Has become. The projection 7 has a rubber cap 25 on the surface thereof, and is configured to ensure that the encapsulation body is pulled out with its elasticity and high friction (slip preventing effect). In addition, since one lead-out arm 10 will have the same structure as the above-mentioned lead-out arm 9, it will make it symmetric about the center axis 0-0 ', and abbreviate | omits description.

The movement control means 11 is a horizontal movement means 26 for moving the projections 7 and 8 in a substantially horizontal direction, and the horizontal movement means 26 is provided with respect to the air check 29 and its horizontal axis 30. The L-shaped portion 31 held by the rotating material and the jack adapter 320 which is supplied with the pressurized air and the piston 33 upwardly moved by the pressurized air and the piston-shaped portion 931 extend upwardly integrally from the piston. It was comprised with the piston shaft 37 which the horizontal pin 36 of the upper part penetrates through the perforation 35 of the substantially horizontal piece 34. Reference numeral 38 denotes a substantially vertical piece with the L-shaped portion 31, and the lead arm 9 is fixed by screws 39, 40, etc. in the same direction. Reference numeral 41 denotes a spring coil, 42 and 43 gaskets, and 58 denotes a solenoid valve for pressurized air supply control.

The horizontal moving means 26 of the lead-out arm 9 has been described mainly. However, the same configuration is applied to the other lead-out arm 10 as well. That is, the L-shaped portion 44 is made of the L-shaped portion 31 symmetrically about the central axis 0-0 ', and the horizontal pin 36 and the perforation 46 (up and down movement of the common piston shaft 37) ( Power transmission, and rotates about the horizontal axis (45).

The vertical movement means (27) is coupled to the rotating material by a slide shaft (47) coaxially connected to the jack adapter (32), its slide guide support (48), the slide shaft (47) and a link (49). The crankshaft 50, the power motor 51, the belt 52, the pulley 53, and the rotation shaft 54 of the pulley, and the pin crank 56 rotates freely on the crankshaft 50. It is composed of a power arm 55 and the like coupled. In addition, 57 is a cam plate fixed to the rotary shaft 54 integrally.

The detailed description of the control means 28, the transfer mechanism 4 of the encapsulated body, and the transfer mechanism 3 of the milk container is omitted here.

In addition, (70) is a mechanism for automatically supplying a new polymer when the encapsulant polymer disappears into the charging container (6), (77) is a photoelectric switch, (78) is an electromagnetic shut-off valve of the air nozzle (61), (79) Is a micro switch, 80 and 81 is a photoelectric switch, and 83 is an automatic control mechanism of the entire apparatus.

Next, the operation of the sealing device 1 of the milk container 7 will be described (see 1-3). First, in FIG. 102, when the polymer of the encapsulation body S is introduced into the charging container 6 from above, the polymer of the encapsulation body S is shunted and loaded due to self-sufficiency. When the arbitrary operation switch (not shown) is turned on, the power motor 51 rotates, and accordingly, the slide shaft (via the belt 52, the pulley 52, the power arm 55, the crankshaft 50, etc.) 47 rises, and the protrusions 7 and 8 of the extraction arms 9 and 10 move upward through the jack adapter 32, the air 29 and the L-shaped portion 31 again. Subsequently, this rise is detected through the cam plate 57 and the micro switch 79, and the control mechanism 83 is operated on the basis of the detection signal, the switching valve 58 is operated to supply pressurized air, and the piston ( 33) is raised. Thus, the piston shaft 37 is raised, the L-shaped portion 31 rotates about the horizontal axis 30, and moves the projection 7 to the other side. In this way, the projection 7 is in close contact with the inner surface of the encapsulation body S, but in the same operation, one projection 8 is also in close contact with the inner surface of the encapsulation body 5 at the same time.

Subsequently, the rotation of the power motor 951 continues and the slide shaft 47 descends and the projection 798 descends while being in close contact with the inner surface of the sealing body S, and the sealing body S is lowered. Just before the sealing body S is connected to the horizontal conduit 59, the switching valve 58 is operated and the air jack 29 is depressurized to lower the piston 33 and the projection 7 98 inward. Move it. The working body S is placed on a horizontal conduit 59 which is separated from the projection 7 98 and has a substantially U-shaped cross section, and is then elastically passed through the inclined conduit 60 by the air nozzle 61. It is held by the holding arms 62 and 63.

Thus, the milk bottle container (e.g., M _{2 of} FIG. 1) moved by the conveyor 68 is removed by hanging the encapsulation body (such as S ₂ ) into the bottle opening and sealing it with the pressing piece 64 again. Press so that is correctly placed (eg M ₃ , S ₄ ). Next, the milk bottle in which the encapsulated body is placed in this manner passes through the heating tunnel 69, and the encapsulated body is heated, and is sealed in close contact with the seal.

상으로 변형한다. 한편, 봉피체(S)는 극히 밀착하여 중적되어 있으나 하단의 것과 그 위의 것과는 철조(18)(19)에 대한 위치관계가 다르고 따라서 변형 정도가 다르다. 이리하여 그 변형 정도의 상이에 따라 양 봉피체간의 밀착이 해제되어 틈(Y)이 생기기 쉽게되고 공기의 침입이 용이하게 된다. 즉 하단의 봉피체(S)만의 강하가 용이하게 된다. 즉 하단의 봉피체(S)만의 강하가 용이하고 확실하게 된다.By the way, in the inner circumference 15 of the lower opening of the charging tube 6 into which the encapsulation body S is to be inserted, except for the portions 16 and 17 corresponding to the elastic directions of the projections 7 and 8, the steel bars 18 ( 19) is made so that the lower edge of the sealing body (S)

Transform into phases. On the other hand, the encapsulation body (S) is extremely close and neutral, but the positional relationship with respect to the barbed wire 18 and 19 is different from that of the lower one and thus the degree of deformation is different. In this way, the adhesion between the two sealing bodies is released according to the difference in the degree of deformation, so that a gap Y is easily generated, and air is easily intruded. That is, the lowering of only the encapsulation body S at the bottom becomes easy. That is, the lowering of only the sealing body S at the bottom becomes easy and sure.

In addition, the sealing device 1 of the above milk container enables sealing of about 8000 pieces per hour. For reference, the dimensions of the encapsulated body at this time are as follows (see Fig. 8).

E: Transparent thin plate (non-shrinkable) plate thickness made of vinyl chloride resin 60 μm outer diameter 39 mm

F: An opaque thin plate made of vinyl chloride resin (uniaxial stretching treatment, shrinking only in the circumferential direction, heat fusion with E)
