Description

The term packaging machine means a machine that automatically packs various products (for example pharmaceutical products in blister packs, flacons, vials or cosmetic products in similar packaging) within the appropriate containers or boxes, if you say _{s: o} want.

The machines mentioned differ fundamentally in two alternatives, that is to say in those in which the introduction the product is placed in the appropriate container while the latter is stopped, and in continuous, in which all phases (introduction of the product, closing of the Container, etc.) without any stopping and in a completely continuous manner Movement, which of course leads to a higher productivity of the machine.

Said continuous packaging machines contain two Feed lines, one for the containers and one for the products, which are fed separately from one another and which lie next to one another on the same level for a certain distance and move at the same speed, a distance on which the product is introduced into the appropriate container.

The feed line for the containers consists of the known ones Machines from a magazine that is above the infeed level for the products is located, and in the stacked one on top of the other the container designed as a flat tube is housed are. In some solutions, the containers mentioned are removed one at a time from the bottom of the magazine, generally by means of suction cups in negative pressure and with an alternative movement, during the

the containers are first pressed against fixed parts which partially open or "keep free" the same make, and then the action of movable bending devices exposed, which should bend the container a little more than 90 ° and try to keep it in the open position to keep. From there, the containers fall between the teeth of an underlying feed chain, which they brings to the station for packing the product. However, it has been shown that opening of only 90 ° is not sufficient is to keep the container open evenly To ensure position, that is, there is the There is a risk that the product will hit one another when it is pushed in, resulting in rejects. Because of this, have other solutions Following the magazine, a rotating drum for removing the containers in combination with a suction device provided, which produced an opening of the container of over 90 °, which, however, inevitably leads to larger dimensions the height of the machine and consequently inconvenient for the operator when refilling the magazine, especially when using the Due to the high productivity of these machines, the frequency of replenishment is taken into account, at 200-300 packs in the minute.

Another disadvantage that these machines have is on them due to the fact that the products are placed in a series of compartments which are the infeed line for them and these, as I said, alongside those of the above

130050/0522

.Λ> · 3103H3

Containers carried by chains are guided, these compartments having to be brought up to the opening of the container at the point at which the product is to be pushed in, so that there are no obstructions. Furthermore, the subjects' j ^e according to the size of the format must be adjustable in their dimensions, and both of these requirements result in a not inconsiderable extensive construction, since it is not possible to simultaneously regulate all subjects with the consequently necessary enormous amount of time for setting of the machine when changing the product format. The main purpose of the present invention is therefore to avoid the disadvantages complained about above and, in particular, to realize an automatic and continuous packaging machine capable of opening the container perfectly and holding it in this position, this container being one in Man-height attached magazine is removed, which develops below the feed level for the products and is therefore easily accessible. A further purpose of the present invention is to produce a machine which can be easily adjusted when the product is changed and at the same time offers a safe assembly of product and container.

These and other purposes are all covered by this Invention achieved of the type comprising a feed line for the products consisting of a number of compartments with at least one pair of annularly closed and around one

A removal device for the containers from this magazine is arranged next to the said magazine, which is designated as a whole by 13 and consists of a pair of Arms 17, which are hinged at the point 18 at the top of the frame 1 and have a pair of suction cups 19 that extend over Lines 20 are connected to a known vacuum device. The arms mentioned are alternately between two opposite positions movable, namely an upper position parallel to the plane of the container 2 and for removal same, if they are inside the magazine (dashed line in Fig. 3), and a lower position with the arms rotated at an <Ä, angle compared to the previous illustration, as shown in full lines in Fig. 3, a position in which the containers are brought to then taken over by the drum 14 below to be able to.

The movement of the arms 17 between the above two positions takes place through simple kinematics with connecting rod and crank, the ii> of Fig. 3 are shown schematically in 21 and their movement by the common drive 22 for the The whole machine, which is mounted inside the frame and is not shown here, is taken up during the distribution of the negative pressure to the suction cups 19 is carried out by a likewise known rotating plate, the movement of which with the the arms match, and the suction cups 19 suck in air, when the arms 17 move themselves in the upper position

find and reconnect it with the atmosphere brings when the arms 17 are in the lower .Position, the container then being "released" by the suction cups 19.

Subsequent to said removal device 13 is with 14 shows a drum with a horizontal axis which moves continuously in the direction of arrow 23, namely tangentially to said arms 17 in their lower position, which is provided with a number of further pairs of arms 24 (see Fig. 6), which are uniform along the circumferential surface In Distances from each other are attached, each of these provided with a corresponding suction cup 25 and on lying on the same plane as the above arms 17, if these are in their lower position and are arranged internally between the aforesaid arms 24, as can be seen clearly is visible in Fig. 8.

More precisely, the drum 14 consists of two parts corresponding to 14 ^V , firmly connected to the frame 1 (even if this part rotates around its own axis 26) and 14 ^XV , which can be moved transversely or parallel to its own axis, namely in in both directions, indicated by 27 in Fig. 5, each of these parts being provided with a retainer of said arms 24 in order to be able to adjust the machines to the different container formats,

three hollow body 30 is connected and this in turn with a likewise hollow shaft 31, which is caused to rotate by a gear wheel 32 which engages in the drive elements of the machine, a number of bending devices 33 are arranged in the direction of rotation of the drum 14, also in point 34 are hinged to the above-mentioned flange 29 and whose task it is to open the container, as can also be seen in the station hy ' ⁿ Fig. 3, by turning clockwise, indicated with 35, as is shown after and then the drum continues to turn.

The rotation of the part 14 * of the drum takes place, as already mentioned, by a mechanical linkage provided by the elements 32-31-30, the latter visible in Fig. 9 and connected to the flange 29, while the part is rotating 14 ^% * takes place through a series of splined shafts 36 which are idly connected to the flange 29 and the corresponding flange 29 ^{v of} the part 14 * ^N , so that it can rotate together with 29 and at the same time move in the direction indicated by 27 . This displacement, which describes the distance between the lines 14 ^N and 14 * ^s and consequently the format of the container, is controlled manually, for example by acting on a gear wheel 37 which engages in a number of further wheels 38, of which each is pulled onto an end screw 39 which lies in the flange 29 * of the part 14 ** (see Fig. 9). It must be noted that the entire drum 14 is overhanging attached to the frame 1 with the help of a pair of bearings 40,

which is located between the hollow body 3T and the attachment 1 ^% . With each grooved shaft 36, as already said idling in the flanges 29 and 29%, a bushing 36 ″ is firmly connected on the side © of the flange 29, which is pulled onto a lever 41 which has a circular toothed section 42 at one end , which engages in a corresponding gear 44 firmly connected to the shaft of the bending device 33, and at its other end a roller 43 which is movable in a profile 45 worked into a frontal cam 46 firmly connected to the frame 1, visible as Outline also in Fig. 6, 3. A small arm 47 is drawn onto the same bushing 36 *, also on the side opposite the lever 41 in relation to the flange 29, in turn to the end of the attachment 24 ″ of the arm 24 with a suction cup attached to the drum. The same also applies to the part 14 ^{NN of} the drum 14. This kinematic connection has proven to be necessary in order to achieve the opening of the container 2 by over 90 °, which would otherwise not be possible, since the bending device 33 counteracts when the right angle is exceeded the edge 48 of the arm 24 would strike. In the solution shown, on the other hand, a small rotation of the lever 41 counterclockwise by the action between roller 43 - cam 46 (rotation that increases as the rotation of the drum 14 increases) corresponds to a rotation of the bending devices by an angle of approximately 150 ° (dashed position T in Fig. 6) compared to the rest position of the same (position in continuous line

nien T), precisely because of the counterclockwise rotation of the small arm 47, which is a slight Lowering of the arm 24 is effected by turning its joint 28 (see the dashed drawing in Fig. 6). The negative pressure on the suction cup 25 of each arm 24 is via a channel 49 through a line 50, which with a Channel 51 is connected, generated, the latter being located longitudinally on the hollow body 30, at the end of which a first ring 52 is attached, provided on the lower side and radially with a series of bores equidistant from each other, as many as there are arms 24. The said ring rotates tightly around an additional coaxial one with a third ring 54 firmly connected ring 53, this third ring 54 in turn at the end of a small Hollow shaft 55 is attached, which runs non-rotatably through the interior of the hollow shaft 31 and at the opposite end to the vacuum pump connected.

The entirety of the rings 52-53-54 forms a general one rotating distributor with the variant in the shape of the cavity 56 of the ring 53, which can be seen in Fig. 6, and the In the cross-section in the direction of rotation of the drum decreases, and this is followed by another cavity 57, which does not coincide with the first connected is.

An additional opening device 58 is fitted between the removal device 13 and the drum 14, basically consisting of a shaft 59 overhanging the frame 1

is worn and with a pair of diametrically arranged Suction cups 60 are provided and move clockwise like rotates according to the arrow 61 about its own horizontal and parallel to the axis of the drum 14 axis. The device has the purpose in accordance with the movement of the Drum to keep the container 2 in the form of a square tube open, since this is due to a bad Carton quality of the containers even under the sole pressure the flexures 33 could not open as opposed to it shown in Figure 3, but could bend as an "L", the consequences of which are easy to imagine. In this case determining suction cup 60, which is only limited by a Rotatlonswtnkel should be under negative pressure (to this For this purpose, a rotating distributor similar to that shown in Fig. 6 is used, even if it has the appropriate cavities and is therefore not shown), and the rotational speed the opening of the container at the beginning of the hold-open.

Dashed lines in Fig. 3 and particularly visible in the cross section of the Fig. 5 is denoted by 62 a second frontal cam, which is attached with a series of equidistant from one another Bulges 63, in the same number as the number of rotations of the drum (in our case six), with an idle roller 64 acting on the cam, attached to the end of a lever 65, which at point 66 the frame is hinged and with the other end 67 to one

Arm 68; this arm is attached like a hinge to an appendix 69 of a shaft 70 (see Fig. 9), which overhangs from the The frame protrudes below the magazine 12 for the container and is provided with a pair of stop elements 71 which Press against the edge of the stacked container and when removing the last container through the removal device 13 Hold on to the containers above so that the weight of the stack does not cause more than one container at a time is removed.

Following the drum 14 or following its feed and therefore above the drum is the above-mentioned removal station 15, also for forwarding the containers to line 4. This station consists of a pair of chains 72 and 73 with horizontal axes parallel to the axis of the Drum 14, which run parallel to each other and closed in a ring around a driven drum 74, which is located in the vicinity the drum 14 mentioned above, and around a drum 75, the movement of which is given by a chain 76 (see Fig. 10), driven by a shaft connected to the general drive means of the machine. To the pair of chains mentioned, which has a horizontal one on the upper side Trum forms, includes a number of supports 78 and

79 (relative to chains 72 and 73), which are equidistant from one another along the evolution of the chains, each of which has a pair attached to the front and a pair of shafts

on the perpendicular to the plane from Fig. 4, or in the two with 81 directions indicated in Fig. 7 slide a body 82 can, the overhanging an inner hollow and at its free end with a series of suction cups 84 provided arm 83 carries which, corresponding to the driven drum 74, describe a circumference C ^ which is almost tangential to the circumference C2 runs through the suction cups 25 on the arms 24 in relation to the drum 14 will be described.

The purpose of the aforementioned station 15 is therefore to remove the containers 2 emerging from the drum 14 with the aid of the arms 83, by negative pressure on the suction cups 84, the negative pressure being delivered through a channel extending from the arm 83 itself consists (see Fig. 7), and through a channel 85 inside the corresponding body 82, connected to a small one Tube 86, which in turn is connected with its other end to the support 78 for the arm 83, which in relation to the continuous feed direction, denoted by 87, follows. The small tube 86 is further inside the corresponding support 78 (see part S in FIG. 4) with a suction cup 88 connected, which runs tangentially during the rotation of the chains and extends to the outer cylindrical surface first ring 89, which rotates with the chains, since it is connected to them via a gear 90 (see Fig. 7). Said ring forms the first of the elements of another rotating distributor, which is exactly the same as that on drum 14 and also has a second and third fixed ring,

corresponding to 91 and 92, the latter being firmly seated on the shaft 93 for supporting the driven drum 74 and with it the vacuum pump is connected. In Fig. 4 is the training of those mentioned as well as their relative positioning.

The displacement in both directions of arrows 81 of the bodies 82 and therefore also that of the arms 83 is carried out by a cam 94 which develops below the shafts 80 and on which the rollers 95 act, which are attached to the underside of each of said bodies 82. This displacement causes the container 2, which is held by the arms 83, to come closer to the compartments 5 which are arranged in front of the arms themselves and which have the same advance speed with them. The mentioned arms 83 slide during their rotation (see Fig. 10) into the space that is described by a group of three rungs 96, 97 and 98, the chains with the corresponding, ring-shaped closed chains running continuously around drums with a horizontal axis 96 ^V , 97 ^V and 98 * are connected, said chains forming the last transport stage of the supply line for the containers. The rungs 96, 98, arranged in correspondence with one another and corresponding to the two outer chains, and the rungs 97, arranged in relation to the inner chain and centered correspondingly to the other two chains, form with their opposite sides receiving elements for the container 2 ( see Fig. 11), and for this purpose the distance between one

130050/0522 ■ / ·

nem pair of rungs 96, 98 and the rung 97 depending on the dimensions, or the width of the container can be regulated. Let us now describe the operation of the machine in question. The products are fed to the corresponding compartments 5, the continuously in the feed direction indicated by 9 slide on.

The magazine 12 is filled with the tubular closed and designed as a flat tube container, which one are stacked on top of the other.

Below the said magazine, a removal device 13 brings its arm 17 in the upper "in Fig. 3 dashed position and with the suction cups 19 Jn contact with the lower surface 2 ^V of the container 2, whereby in this position a rotary distributor with the suction cups is connected, creates a certain negative pressure.

In this phase, the stop elements rotate through a the elements 62 - 63 - 64 - 65 - 68 - 69 formed kinematic Chain in such a direction that they press against the edges of the stacked containers, so that the few that are are under the action of the elements 71 themselves, from the weight of the entire stack in the magazine can be isolated. If then in the immediately following phase the arms 17 begin to turn to look at the full lines in Fig. To bring the position shown in FIG. 3, the action of the suction cups 19 removes only one container that is around a slightly deformed, but sufficient to keep him out of the lower

130050/0522 ^A

Free 16 ^V protrusions of the magazine. At this point the container 2 is brought by the arms 17 into the position indicated by h \ in Figure 3, in which the arms 17 move in relation to the pair of arms 24 which form a station of the drum 14 and which are continuously movable , are arranged inside.

In this situation (as shown in Fig. 8) takes place the "exchange" of the container between the suction cups 19 of the arms 17 and the suction cups 25 of the arms 24. If we have the Looking at Figures 5 and 6, we see that in the case of the drum 14 in this position the ring 53, which is fixed to the drum remains connected, the channel 51a with the cavity 56 of the ring 53, which is connected to the vacuum pump, connects together, the channel 51a due to the mechanical construction the drum is connected to the suction cups of station A] is.

More precisely, this means that each channel 51 of the ring 52 controls the suction cups of the immediately following station in the direction of rotation 23 of the drum 14. The container 2 begins following Lich its way together with the drum 14 and running past the opening device 58 it is partially opened by the suction cups 60 in negative pressure, the negative pressure being generated only for the necessary time and only in the case of containers with a square Cross-section where there are difficulties in the opening phase.
Following the drum in its course, the empty

Roller 43 inside the profile 45 of the cam 46, which by means of the already mentioned lever mechanism causes the bending devices 33 to rotate clockwise and the support arms 24 to rotate counterclockwise (positions T and T ^N in Fig. 6). This progressive rotation of the lever 41 consequently causes a progressive opening of the container through the rotary movement of the drum 14, i.e. an opening of well over 90 °, close to almost 150 °, necessary to allow the material forming the container to snap back elastically during the viewing To avoid less packaging of the same, open one, which is visible in Fig. 3 in the subsequent stations A2, A3, A4, A5, in which the bending devices 33 return to their rest position (see profile cam 46).

A locking template 100 can also be used to secure the containers hold in the open position, which is mainly in during the run-through phase or while it is being held in the machine, in order to allow the containers to snap back elastically avoid.

Note the particular configuration of the rotating distributor cavity 56, decreasing in cross-section and continuing with the suction of the corresponding containers in stations connected to the extraction device. if If we look at channel 51e, which corresponds to station A5, we see that the suction force of the suction cups is much less is (due to losses due to the smaller cross-section)

130050/0522

than, for example, at station A ₁ , which is desirable, however, since the suction force at station A] is very high, because there the container is taken from the arms 17, whereas during the opening phase, that is, as the The container gradually opens.

When the channel 51e comes out of the area of the cavity 56 (section 56 ^ of Fig. 6) due to the rotation of the ring 52, the suction cups are no longer under negative pressure and continue to rotate when the Channel is in the position 51f, the suction cups are in connection with the cavity 57, in which an expansion of the air takes place, which causes the release of the container, which has now been opened. When the container is detached from the drum 14 at station A5, the removal of the same must begin by the arm 83b in Fig. 4, which is connected in the same way as we have seen before to the suction duct 91a, which draws the negative pressure on the arm 83b causes, when this connects to the channel 92a, which is connected to the suction pump, according to the same and already mentioned mechanism as in the case of the distributor of the drum 14, the channel 91a being in connection with the channel 89a of the outer ring 89, on which the suction cup 88a of the corresponding support for the previous arm, which is connected to the suction cup 84b via the above-mentioned small tubes 86, acts in a sealed manner.
The container is removed from station A6 in this way

130050/0522

Completely open form, even in maximum flatness on the opposite side of the flat position that the container has when it emerges from the magazine, which is caused by the Approach at station Ao between arms 24 of drum 14 and the corresponding arm 83, which causes a complete "relaxation" of the container itself, which as it moves on through the subsequent stations A7, Aß and Ag so far goes back elastically so that it comes into a stable parallelepiped shape and remains in it.

During the passage of the container through these stations, it is held by the suction cups 84, which are gradually connected to the suction channels 91a, 91b and 91c, and the body 82 for holding the corresponding arm experiences a progressive displacement by the action of the cam 94 which acts on the roller 95, which causes the container to slide slowly between the rungs 96-98 and 97 and at the same time approach the compartments 5 in the direction of arrow 99, which are arranged frontally and in correspondence and at the same speed move like the chains 96 ", 97", 98 ^v (see Fig. 11). It should be noted that this movement may only take place with the container in the advanced position from station Ag to station A10, i.e. when the container and the corresponding compartment are completely on the same level, so that the small plate 16 is below the Can slide tray 5 (not possible if the tray is still rotated). This is precisely what is possible through the special connection between arm 83 and the corresponding one

Suction on the manifold, i.e. due to the suction on the suction cups of the arm 83f, which takes place through the suction cup 88e, which belongs to the previous arm and is still in connection with the ring 89.

As soon as the suction cup 88e is released from the ring 89, the arm 83f, which is no longer in negative pressure, releases the in the meantime, go to the container positioned accordingly to the compartment and begins its return in the opposite direction to the arrow 99. The container is now in the station A ^ by the rungs 96, 97 and 98 passed and through a pair held by guides 101 and 102 in the position of approaching the compartments and is then held by the sliders 10, the now start their work, filled with the product. After the filling has been completed, appropriate known lifting accessories take the Close the container. As shown in Figures 3 and 4 As can be seen, the number of sections into which the driven drum 74 is divided is greater than that in FIG which the drum 14 is divided (in the illustrated case seven against six). But so that the arms 83 and 24 of the The subsequent stations are always arranged according to one another It is necessary that with the same diameter of the drums themselves, the drum 74 with a slower one Revolving speed rotates as the drum 14; this in order to avoid that on the transition from station A5 to Station Aö, during which the container through the suction cups 84 and 25 is pressed together, a pressing and arching of the-
