Abstract

For example, a process device for recovering cigarettes from a plurality of flip-top packs, having a rotary separator (II), which feeds the packs conveyed therein in the longitudinal direction of the pack to the slit machine (III) at the same position. , The slit machine forms a shallow longitudinal cut in each of the front and rear surfaces of each pack and then transfers it to the paddle unit (IV), and the paddle unit strikes the pack of cigarettes in which the slit is formed to be broken and opened. Packs of cigarettes, tobacco and packaging are then transported to a rotating sloping filtration drum, which consists of pieces of board spaced apart enough to allow only tobacco to pass, separating the tobacco from the tobacco package. With the device, the cut made by the slit machine is made shallow so that it is not possible to cut articles such as tobacco.

Description

Apparatus and method used for unpacking of packaged goods

The tobacco industry is an example of the need for effective means of unpacking. As early as one manager was assigned to each packaging machine to monitor the damaged cigarette packs for a long time, the damaged cigarette packs were collected and then opened by hand and recovered contents such as cigarettes. . In recent years, one manager has jurisdiction over several packaging machines, such as five, which is no longer capable of monitoring, collecting and retrieving contents, thus increasing the need for automatic unpacking facilities.

In the tobacco industry, a cigarette pack cutting machine has already been proposed, which cuts the length of the pack through its upper surface, and the bag is extracted from it by bending the pack in the longitudinal direction around the non-cut side. The operation of the above-mentioned unpacking machine was not ideal because the cigarettes could be broken including the filter part. Contamination of cigarettes by the filter material and packaging fragments is difficult to clean, which causes serious problems in the recovery of reusable cigarettes.

In this regard, the present applicant has developed an apparatus and method for unpacking tobacco products that can facilitate the recovery of tobacco, and such a method for packaging and disassembling the cigarette is disclosed in European Patent A 0,118,289 and British Patent A 2,158,410. The above-mentioned prior applications are hereby incorporated by reference.

However, the two devices and methods described above mainly unpackaged tobacco products, although they could be used to unpack beverages such as tea, coffee and cocoa, and other contents such as food and cosmetics or other suitable articles.

As described in European Patent A 0,118,289, the above-mentioned packaging dismantling device essentially cuts the package at right angles in two directions, and the cutting of the package facilitates the separation of the pieces and the contents of the package, thereby preventing contamination from the pieces of the package. Minimize.

The device according to EP A 0,118,289 is used for opening the packaging of tobacco, the packaged tobacco is cut in half (usually in its length), in this state is released from the pack and the tobacco is in a known tobacco-recovering device. It is then returned from the tobacco paper and filter section and used to produce new tobacco.

It is desirable to have the cigarettes unpacked to return to their best condition intact and to reduce the cost of reprocessing them. Recovery of intact tobacco is not possible with the apparatus and method disclosed in Applicant's European Patent A 0,118,289 and remanufacturing is only an option. By utilizing the instructions in the applicant's British Patent A 2,158,410 to unpack a cigarette, the cigarette can be released undamaged from the package.

Applicant's UK Patent A 2,158,410 discloses a method for recovering tobacco from a packaged article, in particular a flip-top pack of cigarettes, from the packaging, each pack passing through a slit forming step so that two longitudinal slits Produced adjacent to the edge between the rear side and the shallow mating side, the cigarette pack then passes through a second slit forming step, in which one shallow slit is transversely directed to the first two slits through the rear side. It will be formed to cross this. The location of the slit is used to separate a portion of the pack (including the fleet top) from the rest of the pack.

The device disclosed in British Patent A 2,158,410 can process hundreds of packs of cigarettes per hour, which is impractical to ensure that all packs are correctly positioned and fed so that the three slits are placed in or adjacent the rear. Therefore, British Patent A 2,158,410 has a slit forming portion with a double cutter, both front and rear surface is slit to ensure the separation of the flip-top portion irrespective of the position of the cigarette pack passing through the slit forming portion.

The double cutter increases the manufacturing cost of the machine according to British Patent A 2,158,410, and more importantly, it is more difficult to control the cutting depth because the cutters only cut the packaging and do not affect the contents.

UK Patent A 2,158,410, on the other hand, provides improvements to European Patent A 0,118,289 but still requires space for the installation, especially if the machine according to UK Patent A 2,158,410 can handle hundreds of packs of cigarettes per hour. The recovery rate of tobacco products should ideally be 100%, but in practice it is not as expected because the packs are not fully open to release the contents during filtration.

Another problem with the former machine of British Patent No. 2,158,410 is that it is difficult for the cutter to cut only the packaging, for example, cigarettes and cuts that are not damaged by the released tobacco due to the loss of control due to loss of control during misadjustment or use. Mixtures of tobacco can be included, which must be specially filtered and separated from the tobacco to be repackaged and the damaged tobacco by a cutter requiring remanufacturing. The above filtration is difficult and consumes a lot of labor.

In both European Patent A 0,118,289 and British Patent A 2,158,410, the separation of cigarettes from cigarette pack pieces is usually initiated when gravity packs drop by gravity into a chute leading towards rotary filtration drums. This separation can also be triggered by compressing the slit pack of cigarettes as it continues in the drum and, if necessary, leaves the second slit forming portion. Unfortunately, the separation of cigarettes from packs of cigarettes is sometimes incomplete so that some cigarettes can be released from previous devices along the packs of cigarettes and thus not recovered for reuse, so that the recovery rate does not reach the desired level.

The present invention is intended to overcome the deficiencies of the aforementioned conventional apparatus and method.

FIELD OF THE INVENTION The present invention relates to an apparatus and method for use in the unpacking of a packaged article, where consumer goods are usually marketed in the form of a package or box rather than in a disassembled form, but often such articles need to be unpacked. Handling devices are widely used and may cause malfunctions for any reason, resulting in damage to the package. Of course, the packaging may not be available for sale even though the contents are intact, or are subject to degrading value, so that a facility is required to effectively extract contents of particularly substantial value from the damaged packaging or box.

2 is a schematic diagram illustrating a pavement slit forming operation performed in accordance with the present invention;

3 is a top view of the device according to the invention,

4 is an enlarged partial view of the apparatus shown in FIG.

FIG. 5 is a perspective view of the impact device forming part of the device shown in FIG. 3. FIG.

According to the invention, at least one longitudinal slit is cut in each of the front and rear surfaces of each pack to be opened, and no transverse slits are made. The longitudinal slits are located at about the same distance from the mating face of the pack. After the slit forming step, each pack of cigarettes is subjected to a shock that is rapidly applied, and the packs are broken and opened by such a blow, thereby completing the separation of contents from the pack garbage.

Generally, only one slit is cut in the front and rear surfaces and a number of slits are formed in each surface but need not be pressed more than once.

When the present invention is used to open the pack of cigarettes, the risk of cutting the cigarette is minimized, and the change in the slit formation depth due to loss of control or misregulation does not have a significant effect on the cigarette. This is due to the elimination of transverse slits. In addition, the slits are parallel to the cigarette in the longitudinal direction, and the position is generally coincident with the V-shaped hollow between the two cigarettes.

Therefore, according to a feature of the present invention, a method for recovering a packaged article from a package comprises the steps of: transporting a pack of cigarettes that are freely positioned and aligned to the same position and feeding them one by one to the slit forming unit, wherein each pack is a slit forming unit; Forming longitudinal slits on each of the front and rear surfaces of the pack, such that the slits are not deep enough to cut the contents of the pack, and damaged by opening the pack by hitting each pack; And making it easy to deviate the article from the package.

Since articles such as tobacco, for example, are separated from the packaging pieces by filtration, the broken article packaging can be fed towards the filtration means having a gap having a size that passes only the article to be recovered and does not pass the packaging pieces. Separation of the article from the piece of packaging can occur as the package is pneumatically conveyed to the slideway under gravity to fall towards the filtration means, the separation being completed in a filtration device such as a drum formed, for example, into pieces of scrap.

According to the present invention, a method for recovering cigarettes from a flip-top cigarette pack includes a feeding step of supplying freely positioned cigarette packs to the slit-forming parts one by one while aligning them in the same position, and longitudinally in both the front and rear surfaces of each cigarette pack. Forming a slit shallow so as not to cut the cigarette in the pack, and damaging the pack and damaging the pack and leaving all the cigarettes from the pack.

According to the present invention, an apparatus for recovering a packaged article from the packaging includes a conveying means for positioning a freely positioned article package body at the same position and transferring it to a fractionator for discharging them one by one, and the article package body positioned as described above. And a feeder for advancing toward a slit forming section having two slits, each of which can form at least two slits in total, one at each of the front and rear surfaces of the article packaging body, wherein the slits are formed as described above. A conveying means for conveying the object package into the impactor unit to contact the impactor which damages the object package to be opened, and a means for conveying the damaged object package body from the impactor unit toward the separator which is discharged along the article from the piece of packaging. Two slits are installed to cut only the packaging material.

The separators, as in the prior art, have a drum that is formed of a rotationally driven knurled piece, the spacing between the knurled pieces that divide the drum is of a size such that, for example, a cigarette-like article can pass radially from the drum but not the packaging piece. . The drum is preferably inclined such that the packaged piece contained therein flows toward the lower discharge tip of the drum. Alternatively other filtering means, such as a vibrating mesh filter, may be used, the choice of which depends on the type of article to be recovered. Drums formed in pieces are preferably used for recovering tobacco articles such as cigarettes and cigars from the pack.

At least a partial or preliminary separation of the packaging pieces from the article can be made between or within the impactor.

In a preferred embodiment of opening the pack of cigarettes, the fractionator transfers the pack of cigarettes towards the feeder with the tip at the leading end and vertically upright at its side.

In the position described above, packs of cigarettes pass between a pair of horizontally facing slit blades or wheels, and the fractionator may be transported with the tip lying on its head. In this case, the slit forming unit receives the pack of cigarettes with the front or rear face placed on top and passes between a pair of vertically facing slit blades or wheels.

In a preferred embodiment the impactor is a rotating device, which will be described later.

When the pack is blown by the impactor, it is broken into two parts and opened, but is often broken in one end and bent toward the other to spread in a V shape and open in a fan shape. In either case, the contents of the pack are separated from the broken pack.

The detailed description of the invention is hereinafter described in detail in connection with the accompanying drawings which illustrate by way of example.

Figures 1a, 1b and 2 show a flip-top cigarette pack P with a flip-top T, the upper hinge H transversely across the rear surface R of the pack. Is provided, the cigarette pack P has a front face (F) and a shallow side (S) and the end surface (E).

In the cigarette pack P, cigarettes are usually arranged along one of two rows of loading, one of which is to place 20 cigarettes in three rows of cigarettes 7, 7, and 6, and the other stack of rows is 2 The group would have 10 cigarettes, ie each row 2 would have 5 cigarettes.

According to European Patent A 0,118,289 (FIG. 1A) by the applicant, two longitudinally extending slits S1, S2 are cut into the rear surface R along the lines 1, 2 and then the cigarette pack Two are cut along the plane transverse to the slits S1, S2 as shown by lines L1, L2, L3. Of course, the transverse cutting (S3) is made over the entire depth of the pack.

In addition, according to Applicant's British Patent A 2,158,410 (FIG. 1B), two shallow longitudinally extending slits S1, S2 are again cut into the rear surface R, and once again the cigarette pack P is lined ( Along L1) in the transverse direction at S3. In this case, the slit S3 is cut as shallow as the slits S1 and S2 and does not extend through the entire length of the cigarette pack. As a result, a part of the cigarette pack P including the flip-top T is separated from the rest of the cigarette pack, and the cigarette can be released.

On the other hand, if the cigarette pack P is cut in the manner as shown in Fig. 1A, since the cigarettes will be cut into two pieces, recovery is incomplete and must be re-manufactured.

And if the pack P is cut in the manner shown in FIG. 1B, the cigarettes can be recovered intact but some may be damaged, and they must be separated (by difficult operation) and re-manufactured. In addition, cigarettes could be damaged if the transverse slits S3 were too deep and / or if the slits S1, S2 were too deep and / or improperly positioned.

According to the present invention, only longitudinal slits S1 and S2 are formed, and they are formed shallow in the front face F and the rear face R of the cigarette pack P, and no transverse slits are formed. The cigarette pack P is no longer opened by separating the part A including the flip-top T, but is opened by hitting with the impact pad described later. The opening by the blow of the pack (P) allows the cigarette to be released to be suitable for full reuse. The elimination of transverse slits eliminates potential damage to cigarettes, and the slit lines (1,2) have slit (S1, S2) V-shape between successive pairs of cigarettes as shown in FIG. If it is set to coincide with the hollow or curved portion of the risk of damage to the cigarette due to too deep slits (S1, S2) is negligible.

Preferred unpacking devices are devices as shown in FIG. 3 to be described below.

The unpacking machine 10 is provided with a receiving hopper with a feed elevator or conveyor I of any convenient type for conveying a flip-top damaged pack of cigarettes towards the separator II. Preferably the elevator I travels at a constant speed, the speed of which is adjustable and is provided with transverse vanes which certainly face the pack of cigarettes towards the fractionator II. Useful for example is a rotary brush (not shown) located on the conveying surface (II) of the elevator (I) which prevents the packs from bunching together, which is bundled and one rises above the top of the pack. You will hit the back pack. The fractionator establishes an even flow of packaging and is all aligned in the same direction and then fed to the slit forming section III which will be described later. In this slit forming section (III), two slits are manufactured in the longitudinal direction, respectively, which are located on the front and rear surfaces of the cigarette pack.

After the slit forming step, the pack of cigarettes is fed to the paddle unit IV, which ruptures the packs so that the cigarettes are easily released and recovered intact. The cigarette pack leaves the impactor unit IV via a conduit and a dust collector V, and falls into a drum composed of pieces of slanted filtration means VI. The filter means VI finally separates the tobacco from the packaging residue. In addition, the packing residue is discharged in the direction of arrow A at the bottom end VI-A of the filtering means VI.

Tobacco penetrates through the wall consisting of the strips of filtration means VI, and below the filtration means VI a collector for collecting the discharged tobacco and conveying it in the direction of arrow B to release it from the machine 10 or A conveyor is provided. The released cigarettes are then repackaged or subjected to the process required by the manufacturer, and the packaging residues are fed towards the collector part VII in the direction of arrow A. In the collector section VII described above the residues are packaged in a bag for disposal, for example. The collection section VII can be equipped with a commercial double chamber back former, and the residues are compressed to about 5: 1 to increase efficiency.

The cigarette pack P is transported by the lifter I, falls into the separator II, and is freely positioned as it is received by the separator.

The fractionator II functions to arrange the freely-positioned packs of cigarettes and to feed them to the slit forming section III in a uniformly aligned state.

The fractionator (II) and the slit forming section (III) are shown in detail in FIG. 4, wherein the fractionator is a rotary body having an inclined turntable (12) for receiving a pack of cigarettes from the elevator (I). Is inclined and has a bottom face 12a and a bottom face 12b. The turntable rotates at a constant speed but can change its speed, and the pack of cigarettes falls on the table 12 adjacent to the bottom 12a and is transported toward the surface 12b by the rotating table 12. Here, the pack of cigarettes is discharged on the rotating ring 13, the ring 13 is placed in close contact with the fixed side wall 14 of the fractionator II, and the pack of cigarettes reaching the bottom 13 is a ring ( As it rotates 13 it is moved along the side wall 4 and ultimately exits the fractionator II via the outlet zone 15.

The pack of cigarettes withdraws heat and falls on the turntable 12 from the lifter I, some of which are seated on one of the main surfaces, other packs of sides to the side, and other packs of the pack to the end. The classifier (II) rearranges and releases the packs of cigarettes in the same state and position. As they are released, the packs are placed on their sides, the ends of which are moved first, and their main front and rear surfaces are positioned vertically. As described above, in the first step of positioning the pack of cigarettes, the pack of cigarettes is positioned so that one of the main surfaces is in contact with the ring 13. The sack pack is detached from the ring and falls back onto the turntable 12. The means for cutting the cigarette pack P1 has a fixed curved arm 22 which allows the packs of cigarettes to lie flat and spaced apart on the ring, thereby lowering the lower part of the arm 22. By passing through any ring of cigarettes located above the ring 13 and placed on another pack of cigarettes in a "piggyback" manner, the arm 22 drops the pack of cigarettes and falls back onto the turntable. Arm 22 is attached to sidewall 14 in a conventional manner.

The pack P does not have to be placed on the ring 13 so that the front side (or the rear side) is in contact with it, and it is only necessary that the side having the largest size is positioned to be tangential to the ring. In other words, it must travel around the wall 14 fixed on the ring so that its end is leading. The cooperation between the rotating turntable 12 and the ring 13 and the fixed wall 14 causes most packs of cigarettes to take the required position as they move over the ring. Some cigarette packs P2 may be seated on the ring at right angles to the desired position, and the cigarette packs P2 protrude from the inner circumferential end 23 of the ring 13. The fractionator (II) has a device for missing an improperly positioned cigarette pack, for which a fixed inner wall (25) is provided, and the arm (22) protrudes somewhat inward of the inner tip of the ring (13). One free end 24 is provided. The protruding pack P2 is detached from the ring when engaged with the wall 25 or free end 24 and falls back onto the turntable 12.

The pack of cigarettes removed from the ring 13 is returned to the ring by a turntable that rotates through appropriate procedures.

The cigarette pack which has passed through the arm 22 and the free end 24 continuously goes around the fixed wall 14 at the end, and the front (or back; F, R) reaches the bottom with the ring ( 13) All lying on the bed. The final stage of the pack includes rotating the packs so that their sides touch the floor so that the major surfaces F and R are vertical. This can be accomplished by running the pack P along a ramp 26 which is inclined or threaded with the aid of an air jet. The packs of cigarettes travel along the lamp 26 by the thrust of the pack of cigarettes upstream driven by the rotating ring 13 around the wall 14.

The cigarette pack is conveyed to the outlet 15 by the separator II, and then the end S is transported to the slit-forming part III with the end S positioned at the bottom in the vertical state. It is done. The fixed guide wall 27 assists in the process of transporting the pack of cigarettes toward the slit forming portion at this position.

The rotation speed of the turntable 12 and the ring 13 is determined by trial and error according to the size of the separator II and the number of cigarette packs to be processed per minute. For example, a separator having a turntable having a diameter of about 1 m (II) transfers 450 packs of cigarettes per minute to the slit forming part, for example, has a turntable 12 rotating at 60 rpm. The ring 13 typically rotates at a slightly slower speed of 37 rpm. The above speeds are not limited and should be optimized according to the surrounding conditions.

The pack of cigarettes leaving the outlet 15 of the fractionator II flows into the slit forming unit III, and the slit forming unit III and the two continuous running conveyors 31 and 32 and the guide wall ( 27 are connected together to define transfer nip 33. The nip 33 receives the pack of cigarettes P and they are transported past the slits of the slit forming section III.

Each conveyor 31, 32 has respective track bands 34, 36 hooked on pulley wheels 38, 40. The bands 34 and 36 consist of a number of forked belts, for example four belts superimposed on one another. Appropriate pulley wheels 38 and 40 are positionally adjustable to set the nip 33 appropriately to the pack size so that the pack can slip freely from the outlet 15 while ensuring adequate friction grip. The advancing of the pack of cigarettes from the non-slip outlet 15 passes through the slit forming section III. One pulley wheel of each conveyor 31, 32 is coupled to an associated drive motor, not shown, and a single motor can power the drive pulley wheels of both conveyors.

On the other hand, the slit forming section III has a slit in the form of two lateral facing driven rotating slit forming blades or wheels 42 and 44. The blades 42 and 44 are motorized to counter-rotate with each other and the spacing between the blades is adjustable, such as the height relative to the substrate on which the pockets are advanced by the conveyors 31 and 32. This adjustment of the spacing affects the depth of the slit formed in the main surface (F, R) of the pack, and the adjustment of the height is adjusted to place the slit in the V-shaped hollow between neighboring cigarettes as already described. .

Two cutting blades are provided in the slit forming portion. Thus, one slit is formed in each of the main surfaces F and R of the cigarette pack. If desired, the blades 42 and 44 can be composed of multiple blades, producing longitudinally extending slits in one or more of the respective major surfaces F and R. However, it is not necessary because of the complexity of the resulting machine.

After the cutting blades 42 and 44 slit the front and rear surfaces F and R of the pack, they are advanced by the conveyors 31 and 32 into the paddle unit IV. The unit is shown in FIG. 5.

In FIG. 5, the impactor unit IV has a generally drum-shaped casing 50 with an outlet port 54 tangentially provided with the inlet port 52, with the conveyors 31, 32 being approximately per minute. The pack of cigarettes is transferred into the inlet port at a speed of 450. The actual speed will depend on the output of the fractionator II. The inside of the casing 50 is a wire rotary frame 56 driven by the motor 58 in the direction of the arrow C. The rotary frame 56 is usually made of a round bar having a diameter of about 6.3 mm. The rotary frame 56 also has a frame made of two rings 60, 62 fixed to a driven, rotationally journaled bottom plate, not shown. The ring described above is joined by eight 6.3 mm bars 64 in this example. The casing 50 has an inner diameter of 50.8 cm, and the rotating frame has an outer diameter of 49.5 cm. The casing is rotated at a speed of, for example, 2000rpm between 1600-2500rpm, and can utilize the usual trial and error to optimize the rotational speed of the firebox 56.

Since the described rotary frame 56 may be circular in plan view but may have a different shape, it may take the shape of a square or other common rectangular shape in the plan view or polygonal shape such as hexagon rings 60 and 62 in plan view.

In use, the pack of cigarettes entering the casing 50 via the inlet 52 is hit at least once by one of the bars 64 with a force sufficient to break the pack of cigarettes as described above. These broken packs and the cigarettes derived therefrom are swept towards the outlet port 54 by the rotary frame under the aid of the air draft generated by the frame 56.

The outlet 54 is connected to a 15 cm inner diameter conduit leading towards the cyclone separator 68, and the pack of cigarettes and tobacco are moved along the conduit 66 towards the cyclone separator due to the low speed air flow generated by the frame 56. Solids (tobacco, packs of cigarettes, etc.) are separated from the airflow in the cyclone separator 68. They fall through the separator 68 and enter the filtering means VI.

Separation of tobacco from the pack of cigarettes is initiated in the paddle unit V and passes along conduit 66 and proceeds as it falls into the cyclone separator 68 under gravity.

The cyclone separator conveys the cigarette and pack of cigarette packs into the open upper tip of the filtration means VI inclined downward. Separation of the tobacco is completed in the filtration means VI, which is a drum 70 formed of cylindrical slabs. The drum rotates around an inclined longitudinal axis, and the wall of the drum is partitioned into longitudinal longitudinal pieces that are tight enough for the tobacco pack residue to pass through while being spaced enough to allow tobacco to pass. The residue here is ultimately discharged in the direction of arrow A as it is discarded from said tip of the drum. In the meantime, the tobacco passing through the wall of the drum falls in the direction of the arrow, for example onto the discharge conveyor.

Although the above description has been made of the tobacco recovery machinery, the principle of operation of the method according to the invention can be embodied in a machinery for recovering this content without damaging other contents from the packaging.

Under certain conditions, cigarettes may be contained in a pack of cigarettes that are wider than their length (length is considered to be the longitudinal direction of the cigarette), which pack may be contained in an inner tray holding the pack, and the device may It can also be easily used to extract tobacco from a pack of cigarettes.

It is used to open the package to minimize the risk of damage to the packaged goods, and the change in the slit formation depth due to loss of control or misadjustment does not significantly affect the packaged goods damage.
