The present invention relates to a film packaging binding device that is securely tightened without generating slip and facilitates replacement of the mold.

FIG. 12 is an external view showing, for example, sausages and the like processed into a cylindrical film package.

The film package 16 is, for example, a copolymer of vinylidene chloride and vinyl chloride, in which a biaxially stretched film 1 is formed in a tubular shape, and is welded at a high frequency in accordance with its periphery to form a weld line 2. Will be. Both ends of the cylindrical film 1 are concentrated in the state in which the cylindrical package 16 is filled with contents such as processed meat, and the wire clips 3 such as aluminum are tightened to bind.

FIG. 13 shows a schematic structure of a conventional continuous filling packaging apparatus for forming a cylindrical film package 16 to fill the contents therein and to focus and bind the film package 16 at regular intervals.

In FIG. 13, reference numeral 4 denotes a metering pump, and 5 denotes a filling nozzle connected to the lower part of the metering pump 4. The contents of processed meat and the like are sent from the supply pump (not shown) installed on the floor of the workplace and transferred to the dosing pump 4 through the supply line, and in the dosing pump 4, the manufacturing speed of the film package 16 is In accordance with this, the contents are sent to the filling nozzle 5 as a constant flow rate.

A molding member 6 is provided around the upper portion of the filling nozzle 5. The film 1 drawn out of the original plate 7 in a planar shape is introduced into the guide rolls 9a and 9b and bent at an upper circumference of the cylindrical molding member 6, and the inner surface of the molding member 6 is formed. It is shaped into a tubular shape along. The high frequency electrodes 10 and 11 are provided in the lower position of the shaping | molding member 6, and the circumferential parts of the shaping | molding member 6 are welded by the high frequency electrode 10 and 11 by high frequency welding, and the welding line 2 is carried out. Is formed. The contents are continuously filled by the filling nozzle 5 in the cylindrical film package 16 thus formed.

At the lower position of the filling nozzle 5, film feed rollers 12 and 13 are provided, and the cylindrical film package 16 filled with the contents is moved downward by the film feed rollers 12 and 13. Is sent continuously. In addition, the lower packaging mechanism 14a is periodically driven in the direction indicated by the arrow in FIG. 13, and the film packaging body 16 into which the contents are put is flattened at regular intervals by this operation. When pressed by the powdered rollers 14 and 14 of the film package 16 into which processed meat and the like are put, the contents are divided up and down in this portion and the films are kept in flat contact with each other.

A binding / cutting unit 15 is further disposed below the pair of powder rollers 14 and 14.

As a result, the binding / cutting unit 15 is configured to reciprocate up and down in accordance with the falling speed of the film package 16 in which the contents are divided and lowered. The binding / cutting unit 15 is provided with a pair of moving members 15a and 15a on the left side with a film package 16 mounted thereon, and a focusing plate 15b and a mold are provided on the respective moving members 15a and 15b. 15c is integrally formed.

On the right side, a pair of focusing plates 15d and 15d arranged up and down and two upper and lower molds 15e and 15e arranged inside each of the focusing plates 15d and 15d are provided. 15f of cutting knives are provided in the middle.

When the left moving members 15e and 15e move from the right direction to the left focusing plate 15d by the mechanism in the binding / cutting unit 15, the contents of the film packaging body 16 are divided. The flat portion is focused on the focusing plate 15b and the focusing plate 15d. Immediately thereafter, wires such as aluminum are fastened by the mold 15c and the mold 15e, and 32 places attached to one knitting portion are bound as aluminum wires to form a ring-shaped wire clip 3. In addition, the film is cut | disconnected in the middle of the upper and lower wire clips 3 by the cutting knife 15f, and is separated into the individual package shown in FIG.

In the wire bonding operation of the binding / cutting unit 15, the wire is first deformed into a U shape, and the U-shaped wire is pressed in the molds 15c and 15 to form a ring shape as shown in FIG. To form a wire clip (3).

At this time, in the mold 15c on the side of holding the U-shaped wire, a slip occurs between the U-curved portion of the wire and the inner surface of the mold 15c during the tightening operation, so that the wire 15c, 15e) is not pressed firmly to form a wire clip (3) of the normal form. In such a case, the tightening jig of the wire with respect to the film is in a bad state, which causes a problem that the package cannot be reliably sealed.

Moreover, on the left side shown in FIG. 13, the focusing plate 15b and the metal mold | die 15c are integrated, and the moving member 15a is formed. The mold 15c and the opposing mold 15e approach each other at a predetermined cycle, and the film is bound by deforming the wire into a ring shape by sandwiching and pressing a wire such as aluminum between the molds. Therefore, the metal mold | die 15c, 15e is a part with severe friction, and needs to be replaced regularly in maintenance work.

However, if the connecting plate 15b and the mold 15c are integrally formed in the same block as in the conventional example shown in FIG. 13, the focusing plate 15b must also be replaced when the mold 15c rubs. Since the focusing plate 15b merely focuses the film, there is almost no friction, and it is complicated to replace it with the mold 15c. Moreover, since the moving member 15a in which the focusing plate 15b and the mold 15c are integrated is attached to the movable part of the drive mechanism, the work of replacing the entire moving member 15a becomes complicated.

The present invention has been made to solve the above-mentioned problems, and to provide a film packaging binding device that can securely press and deform wires so that the film can be tightened, and the replacement work can be simplified when the mold is rubbed. It is aimed.

At this time, the shaft 68 in the guide block 65 is driven clockwise and the shaft 69 is rotated counterclockwise by the driving ring 73 shown in FIG. 7, and the upper nose 76 and the lower nose ( 77 faces the front of each wire W and W. As shown in FIG. Therefore, as shown in Figs. 11A and 11B, when the noses 76 and 77 are inserted into the grooves 46d and 47d of the cutting members 46 and 47 described above, The wires W and W are bent in a U-shape so that the U-shaped wires W and W are held in the cutting members 46a and 47a (see FIG. 11 (b)). After the wires W and W are bent in a U-shape, the gear plate 72 is driven clockwise by the drive ring 73 as shown in FIG. The gear plate 71 being fitted is also driven counterclockwise. Thus, the shafts 68 and 69 are driven in opposite directions to each other so that the noses 76 and 77 move away from the moving region of the wire cutting members 46 and 47.

In addition, when the left and right moving blocks 27 and 35 are approaching each other, as shown in FIG. 9, the front end of the left focusing member 41 is the focusing groove 41e of the continuous plates 41b and 41c. In the focusing grooves 93d of the right focusing plates 93a and 93b, the flattened portion 16a of the film package 16 is focused. In addition, when the left and right moving blocks 27 and 35 are approaching, the sleeves 92 and 92 supporting the right focusing plates 93a and 93b are moved by the spring 94, While sliding 94), the guide shafts 91 and 91 slide to move to the right.

If both moving blocks 27 and 35 are approaching, the front ends of the positioning shafts 61 and 61 fixed to the retaining block 48 as shown in FIG. 10 are guide shafts 91 on the right side. , 91) at the front end. At this point, the pressing arm 56 is rotated counterclockwise through the driving arm 58 and the shaft 55 by the lowering of the contact surface between the floor roller 59 and the flat cam 29a shown in FIG. As shown by a dotted line in FIG. 5, the pressing block 56a is pulled out from the rear surface of the holding block 48. As shown in FIG. Therefore, after the positioning shafts 61 and 61 fixed to the holding block 48 contact the guide shafts 91 and 91, the movement of the holding block 48 and the wire cutting members 46 and 47 held thereon is regulated. Then, in the movement of the moving block 27 in the right direction, the guide shafts 49 and 49, which the elastic springs 52 and 52 contract and are fixed to the retaining block 48, are supported by the bearings on the movable block 27. (51, 51) Slide inside me.

Therefore, after contact between the positioning shafts 61 and 61 and the front ends of the guide shafts 91 and 91, the wire cutting members 46 and 47 fixed to the retaining block 48 do not move in their positions. The guide protrusions 43e and 44e of the binding mold 43 and 44 slide in the sliding grooves 46a and 46a of the wire cutting members 46 and 47, and the concave at the front end thereof. The points 43g and 44g and the recesses 96a and 97a of the molds 96 and 97 on the right face each other with the U-shaped wires W and W interposed therebetween, and the wires W and W shown in FIG. In the form of a wire clip 3 is clamped in two places of the film 1. At this time, as shown in FIG. 3, the wires W and W are formed in the small recesses 43h and 44h formed on the inner bottom surfaces of the recess 43g and 44g of the binding mold 43 and 44, respectively. Since the curved portion enters and fits, the film 1 is reliably tightened by the wires W and W without the wires W and W being slid and the wire clips 3 are formed at two positions above and below. The shape of the small recesses 43h and 43h is not particularly limited as long as the wires W and W partially penetrate therein and are tightened so as not to slide in the mold when they are tightened. Arbitrary planar shapes, such as a polygon, a circle, and a cone, are about 0.5 mm deep.

Both moving blocks 27 and 35 approach each other so that the engagement molds 43 and 44 and the recessed portions 43g and 44g and 96a and 97a of the molds 96 and 97 are completely in contact with each other. Just before the tightening of the wires W and W, the roller 106 shown in FIG. 4 abuts against the stopper 107, and the driving arm 103 is moved by moving in the left and right directions of the moving block 35. FIG. Driven clockwise, the cutter support block 101 moves to the left, and the cutter 100 is driven to the position where the film 1 is penetrated as shown in FIG. The film 1 is cut | disconnected in the middle of the part in which (3, 3) was formed.

After the binding / cutting operation is completed, the moving blocks 27 and 35 are driven in a direction in which the moving blocks 27 and 35 are separated from each other by rotation of the input shafts 23 and 31 shown in FIG. After the positioning shafts 61 and 61 fixed to the retaining block 48 on the left side and the guide shafts 91 and 91 on the right side are separated, the wire cutting members 46 and 47 and the binding molds 43 and 44 are mutually The position is in the state shown in FIG. 2 and returns to the left direction.

At this time, as shown in FIG. 7, the driving ring 73 is driven in the right direction so that the shaft 68 is counterclockwise and the shaft 69 is driven clockwise. Therefore, as shown in FIG. 8, the upper nose support block 74 is rotated counterclockwise, and the sleeve 78 is applied counterclockwise by the force of the spring 82, and the spring ( The detection pin 79a is pressed against the upper surface of the wire cutting member 46 by the elastic force of 82. Since the lower nose support block 75 is driven in a clockwise direction, this also pushes the sleeve 85 clockwise through a spring 89, and the lower detection pin 86a is a piercing cutting member ( It is pressed on the bottom of 47).

When the wire cutting members 46 and 47 are returned to the position shown in FIG. 2, the detection pins 79a and 86a which are subjected to the biasing force of the springs 82 and 89 as described above are cut by the wire. The detection holes 46e and 47e of the members 46 and 47 enter the fastening recesses 43g and 44g of the binding molds 43 and 44, respectively. This state is shown by the dotted line in FIG. When the detection pins 79a and 86a enter the recessed portions 43g and 44g, the detection plates 81 and 87 of the upper and lower portions shown in FIG. 8 move together with the detection pins 79a and 86a. Proximity switches 83 and 88 are detected.

That is, when the detection output is obtained from the proximity switches 83 and 88, the wires W and W do not remain in the recesses 43g and 44g of the respective binding molds 43 and 44, and the detection pins do not remain. It is possible to detect that the 7979 and 86a has completely fallen into the recessed portions 43g and 44g. On the contrary, when the wires W and W remain inside at least one of the recesses 43g and 44g of the binding molds 43 and 44 returned, at least one of the detection pins 79a and 86a is recessed to 43g, 44g), the detection output from at least one of the proximity switches 83 and 84 is not obtained.

As shown in FIG. 11 (c), the above-described detection operation does not perform reliable binding by the wires W and W, and the operation is performed when the wires W and W remain in the binding molds 43 and 44. FIG. It can interrupt, and it can prevent that wire W, W is cut again.

Further, when the binding operation is completed and the left moving block 27 is moved in the left direction, the movable block 48 is applied to the right direction in FIG. 4 by the elastic spring 52, and this moving block ( 27) and the focusing member 41 fixed thereto are returned to the left in advance. At this time, the pressing arm 56, which is applied clockwise by the spring 57, is returned to the posture indicated by the solid line in FIG.

In addition, when the concave portions 43g and 44g of the binding molds 43 and 44 are worn out by repeating the above-described binding / cutting operation, the wire cutting members 46 and 47 shown in Figs. Can be removed and the bolts 45 can be removed to remove the binding molds 43 and 44 from the focusing member 41 and replaced. At this time, the focusing member 41 may be removed from the moving block 27, but it is also possible to work without removing the focusing member 41. The mold block 95 on the left side can also be replaced as a unit.

In addition, in the above embodiment, as shown in FIG. 4, the drive arm 103 is connected to the cutter support block 101, and the roller 106 provided on the drive arm 103 is in contact with the stopper 107. As a result, the cutter support block 101 is driven through the driving arm 103 so that the cutter 100 protrudes in the left direction. Therefore, after the clip 3 which binds with the wires W and W is formed, the timing until the film 1 is cut | disconnected by the cutter 100 is minute, and adjustment operation is difficult. Here, the cutter support block 101 may be driven by a cylinder mechanism or the like to cut the film by advancing the cutter 100 with sufficient allowance time after the binding is completed.

In addition, according to the binding device of the present invention in which the binding molds 43 and 44 have the small concave portions or the small convex portions, the film package 16 to be manufactured has its wires corresponding to the concave portions on the outer surface of the lip 3. The concave portion corresponding to the projection or block portion to be made.

All. Effect of design

As described above, by forming the block portion or the recessed portion on the inner surface of the recess for joining the mold, it is possible to prevent the sliding of the wire in the mold when the wire is tightened, and to perform reliable work.

In addition, since the focusing member and the mold can be separated, when the mold is worn out by repeating the binding operation, only the mold can be removed from the focusing member and replaced. Therefore, it is not necessary to replace the unworn focusing member. In addition, this mold replacement can be performed while the focusing member is attached to the apparatus, so that the replacement is easy.

In addition, since the mold is accurately positioned on the focusing member by uneven fitting, the relative positional accuracy between the focusing member and the mold can be increased, and the mold is fixed by the screw. Can be exchanged.

And by integrally forming the guide block in which the wire cutting member slides, there is no need to provide a mechanism for guiding the focusing member, and the structure of the focusing plate can be simplified.
