Description

The invention relates to an apparatus and a method for Leveling of unevenly thick filled bags.

Leveling is understood to mean a process in which a Bag that is particularly thick with uneven thickness a good is filled, is reshaped such that an esp especially evenly wide or thick bags over the height  arises. This creates bags of uneven thickness, that in one on one side, usually the top, open Bag a good introduced using gravity becomes. Due to the elasticity of the bags and the weight of the The bag bulges particularly well on the bottom so that, seen in section, a bag with roughly teardrop-shaped contour. Especially with the manufacturer development of so-called 4-sided sealed edge bags, in particular for packaging food, such as ready-made soups in powder form, are used, especially during the filling process made sure that in the area of the still open, mostly the upper Seal edge of the bag, no goods arrived, otherwise at the subsequent sealing process the sealing seam is not tight can be attached. For this reason it is used for filling a filler tube brought close to the bottom of the bag and the material to be filled emerges from the opening at the end, for example, dried, granular soup powder and others Ingredients such as dried vegetable particles or pasta, out. With this filling method, bags are created in the bottom area are particularly bulged. Bulges arise even if a relatively coarse good with a relatively large one Speed is introduced into the bag, for example Candy or gummy bears.

Such bulbous bags, which are mass-produced and filled, all have about the same bulbous Structure on so that the bags are stacked over the bulbous Structure of very wide or high stacks, depending on the stacking direction, results in a in the area of the thin end of the bag have considerable space. To such bulbous bags Being able to pack them in cardboard boxes saves space  equalized to one evenly across the height and width to get filled bags.

In a known method or with a known Vorrich as described by the applicant under the name "Krempel wepamat, bag packer VSB 802 "is distributed, the Equalization in that the bag with the bulbous side be carried out first between two rollers, one Have a distance from each other, the thickness of the equalized Bag corresponds. When the bag passes through the two spaced rollers that will be the distance across protruding material pressed into the area of the bag by the rollers, in which very little material is recorded. This kalan The three-way process has the disadvantage that the bag apply relatively strong pressure forces that can cause that if the goods are not quick enough the pressure of the rollers can evade by moving, the bag bursts. Further it was found that if relatively hard goods in the bags is included, for example, hard noodle pieces in soups bag, hook them while rolling and through the bag wall can sting. During the subsequent transport, this can be done fine-grained soup powder through these holes from the bag emerge. This injury to the bag skin doesn't just result for the exit of goods in the bag, but opened also the possibility of contamination from the outside or germs can enter, which is the case with pouches, the food record leads to significant problems. Furthermore, after partly in such a leveling that by the pressure the material in the bag is crushed can, for example, with parts that have a liquid included, such as filled candies or the like  causes the content to become unsightly and to become misshapen Mass glued.

It has also been suggested that if there is a good thing to get caught tends to be specially trained, such as gummy bears To use toothed rollers by engaging the teeth with the Well equalize this and distribute it. This equalization method is very complex and requires special coordination a device on a very special good, also then it is not ensured that the goods are not damaged will, d. i.e., for example, separate gummy bears be torn. Such a device would then be for one other product no longer usable, since it is completely specially designed for the consistency and geometry of the goods is.

The object of the present invention is therefore a method and a device for leveling unevenly thick to create filled bags in which simple and without loading Risk of damage to the goods even distribution of the good in the bag can be achieved without being constructive complex measures to adapt to different types of goods, Different types and sizes of bags should be possible.

According to the invention, the object is achieved in a device solved that means are provided that in the bags Set the goods in motion in such a way that together effect with gravity the goods are equalized.

According to the invention, the object in a method is thereby solved that the bags are vibrated in such a way that the goods in the bag are moved in such a way that in cooperation with gravity is being equalized.  

According to the invention, the bags are set in vibration, whereby the goods received in the bags start to move. The vibration is selected so that a uniform Distribution of the goods in the available in the bag Space is guaranteed. Gravity imposes on the good a certain force component in a direction that in Overlay with the swinging motion for a controllable Orientation or alignment of the goods in the bag ensures. Becomes for example, put a bulbous bag on its side and vibrated in the horizontal and vertical directions, so the superposition of the horizontal movement with the vertically acting gravity for an equal moderate distribution of the goods in the lying bag. So it is no longer need mechanical devices such as rollers or toothed rollers must press into the bag. The Amplitude, frequency and duration of the vibration can then be optimally adapted to the goods ingested, without making expensive changes to the devices are necessary. It is also excluded that the good zer being squeezed or broken, or that fragments of the good pierce the wall of the bag.

In a particularly advantageous embodiment of the invention the leveling device has means for receiving and transporting the unevenly thick filled bags on which this vibrates over a distance in contact with brings transferred funds.

This measure has the advantage that in continuous operation bags can be equalized. The seized Bags can then be placed in an appropriate position, i.e. for example lying prone, standing or inclined and during  a certain distance in contact with the means that cause the vibration. The equalized bags can then be transported on to a Packing station are brought.

In a further preferred embodiment of the invention the bags are standing, with the thicker section at the top located, transported via the vibrated means.

This measure has the advantage that gravity in the Direction acts in which the goods must be moved. So it is then only necessary to vibrate the bag in this way put that the good out of the drops put on the head Form moves out due to gravity, taking the good then has a tendency to drop into a geometry again to pass, but with the opposite bulge. Here the good goes through an intermediate state which is exactly the same sized state, where then at this point Vibration process is interrupted and the equalized bag if necessary moving further horizontally so that the equal position of the goods is maintained. That in Schwin gung offset can be particularly advantageous in the direction gravity or by swinging along a vertical Level can be achieved. Becomes a standing bag in gravity direction vibrated, vibrated or shaken, see above the equalized state is closed within a few seconds achieve, depending on the type of good by one for this good optimal amplitude and frequency of the oscillatory motion is applied in order to keep the leveling process as short as possible hold, i.e. equalize the highest possible throughput to receive the bag in a device according to the invention.  

In a further advantageous embodiment of the invention assign the means for receiving and transporting the Pouches on an encircling element that is several pocket-shaped Includes transducers, each containing at least one bag is recordable.

This measure has the advantage that a special structurally simple measure simultaneously several bags gradually seized, transported and then one Processing station can be fed. These Measure contributes to an increase in throughput at the same time timely safe guidance of the bags in an inventive Device at.

In a particularly advantageous embodiment, this is the case running element as an endless running around at least two waves band formed, of which the pocket-shaped transducers perpendicular stand out.

This measure has the advantage of being compact, endless operable mobile device for picking up and transporting is created.

In a further particularly advantageous embodiment of the Invention is every pocket-shaped pickup through in tape running Direction one behind the other, sheet metal arranged at a distance.

This particularly constructively simple and robust measure allows you to pick up and guide bags of any kind and Consistency so that with a single such device very differently designed bags are transported can.  

In a further advantageous embodiment of the invention the at least two waves are horizontal and level arranged, and the vibrated means are under half of the lower circumferential pocket-shaped pickups arranged.

This structurally particularly simple measure benefits the heavy force for the implementation of the present invention in in two advantageous ways. The roughly horizontal running belt encircling pocket-shaped pickups, while either along the top or around the redirector points are filled with bags and carry them, as they run along the bottom of the band, along the immediately below the pocket-shaped recesses arranged vibrating means, the bags due to the Gravity tends to stick out of the pocket step out, whereby they can do so far, until they hit the vibrating means. The bags shaped gripper then include the fork in vibration offset bags, give it a certain movement freedom, but at the same time ensure leadership and onward transport via the stationary vibrating Medium. The frequency, the amplitude and the speed of the rotating element is then set so that the in the goods picked up are just equalized after the bags over the vibrating means, thereby on them dormant, were led. The bags can then be used, for example simply from the open pocket-shaped transducers slip out or fall and for example a ver packing unit are fed.  

In a further particularly advantageous embodiment of the According to the invention, the means set in vibration Plate on the spring means via a vibrator connected, with the pouch resting on the plate over these are transported.

This measure has the advantage that a simple frictionless and smooth transport of the bags over the plate is possible, i.e. the bag is not affected. The pig Generation generator can by ultrasound equipment or by itself known electrically controlled vibrators are formed. It is also possible with mechanical goods Vibration generators such as eccentrics or the like to work. The plate can, for example, in a vertical, in a horizontal or in a wobbling swinging motion depending on whether the bag is standing, lying or inclined Way over the plate.

In a further advantageous embodiment of the invention stopping means are provided that a movement of in Vibration displace bags from the vibration producing Limit funds directed away.

This measure has the advantage that the bags in the the vibrating means stimulated movement not too far stand out from these, but immediately against the stopping means bump and from this back in the direction of gravity the vibrating means are encountered.

This measure has the advantage that the bags are not affected by the Jump the vibrating means away, but soon again  get in touch with them, which means that a new Vib rations impact on the good, so that it is very quickly moved to the desired equalized position. Thereby, that the bags are not very far from those which generate the vibration can withdraw the funds, they do not come up with high Speed back on these means so that ensures is that the edge of the bag is not bent, which would make him unsightly.

In a particularly constructively simple embodiment of the Invention, the stopping means have a stationary stop rail, and the transducers on both sides of the Stop rail extending sections along the Stop rail are moved.

This measure has the advantage that the bags of the Aufneh laterally guided between the swinging bottom Plate and the fixed stop rail are transported, taking these bags by choosing a certain distance one more between the vibrating plate and the stop rail or less little possibility of free jumping on the own vibrating plate.

In a further advantageous embodiment, means for Feeding bags provided that the bags in about horizontal, pocket-shaped transducers at one end Introduce the deflection area of the endless belt.

This measure has the advantage that the each bag in a straight, horizontal position Transducers can be introduced.  

In a further advantageous embodiment of the invention the means for feeding consist of a conveyor belt, the Control in this way with control of the rotating element is connected that a bag can only be brought if an empty pocket-shaped pickup at the end of the conveyor Conveyor belt lies.

This measure has the advantage of ensuring that one bag each in a pocket-shaped sensor is brought, whereby it is ensured that only then a bag is brought into the transducer if this is directly in front of the Band lies and is also empty.

In a further advantageous embodiment of the invention means are provided for removing the equalized bags, which enable the equalized bags to be turned.

This measure has the advantage that, as desired, the bags can be continued as they are from the pocket-shaped Fall out transducers, or that they can be turned. This turning process is often when equalizing standing bags desirable with a legible Be are provided with the lettering and with the standing equalization yes upside down, because when filling the bulge yes arises at the bottom. Leave the equalized bags then the pocket-shaped receptacles, if they are, for example due to gravity from the pocket-shaped recesses fall out, stand on your head, so that it often it is desirable to turn this over so that it can be used be fed to the bottom of a packaging box and inserted there again using gravity  so that they can be there in the right way are included, i.e. for open boxes, their labeling is perceptible for reading.

It is understood that the above and the following standing features to be explained not only in each specified combination, but also in other combinations and can be used alone, without the scope of the to leave the present invention.

The invention is selected below on the basis of a few Embodiments in connection with the accompanying Drawings described and explained in more detail. Show it:

. Figure 2 shows schematically three adjacent stacked bags before and after equalization;

Fig. 3 is a section along the line III-III in Fig. 1;

Fig. 4 is a partial representation corresponding to the representation of Fig. 1 of another embodiment of the invention of a device for leveling lying bags, and

Fig. 5 is a highly schematic plan view of a further inventive embodiment of a device for leveling of standing pouches.

A device 10 according to the invention shown in FIGS. 1 and 3 has means 11 for receiving and transporting bags 24 to 32 .

Bags 24 to 32 are so-called 4-sided sealed edge bags, and are used to hold fine-grained goods in the form of dry ready-made soups.

The means 11 for receiving and transporting the bags have an element 12 which rotates around two level, horizontal shafts 14 , 16 and which is a chain belt in the exemplary embodiment shown in FIG. 1.

The peripheral element 12 is provided on its outside, in the illustration in FIG. 1, with sixteen pocket-shaped receptacles 18 which are U-shaped in the side view of FIG. 1 and are open at the end facing away from the peripheral element 12 .

Each pocket-shaped pickup 18 has two sheets 20 , 21 projecting perpendicularly from the rotating element, which are connected to one another on the side of the rotating element 12 by means of a web (not shown here).

Each sheet 20 , 21 consists of two spaced-apart, side-by-side sheet strips (see Fig. 3 strips 21 , 21 ').

Underneath the rotating element 12 there are arranged oscillation means 36 , which have a plate 35 which is resiliently connected to an oscillation generator 40 , this being represented schematically in FIG. 1 by a spring 38 . The vibration generator 40 can be a mechanical agitation, an eccentric, an ultrasound device or an electric vibrator.

The plate 35 is arranged such that it comes to lie at a short distance below the outer transverse edges of the sheets 20 and 21 respectively.

In the illustration of FIG. 1, a feed conveyor belt 22 is arranged on the right side, the upper band surface is located at such a level that a resting on the belt 22 bag 24 can be horizontally aligned placed in a horizontally aligned pocket-shaped receiver 18, as the bag 25 is shown. The belt 22 rotates at such a speed that a bag 24 , as indicated by an arrow 23 in FIG. 1, is thrown into the ready receiver 18 due to the inertia of the mass. Since this process takes a certain amount of time, the rotating element 12 stands still for this process, a control (not shown here) of the rotating element 12 being coupled to the control of the feed belt 22 such that, as shown in FIG. 1, only one Bag 25 is shot into a pocket-shaped pickup 18 provided. Thereafter, the circumferential element 12 moves, as shown in Fig. 1, along an arrow 17 until the next, the transducer 18 trailing on in the horizontal recording position before the end of the belt 22 is pivoted to then take the bag 24 .

The bags 24 and 25 lie on the feed conveyor belt 22 in such a way that their bottom end 50 , in the region of which the bag is bulged, runs ahead. In the area of the head 48 of the bag 24 , no good 24 'is added at all, ie the inside of the bag lies against one another. This unevenly thick training in the longitudinal direction of the bag 24 results from the filling process of the bag 24 , which was open when filling at its top 48 and the good 24 'was filled in such that no particles remain in the area of the head 48 , so that this Safe area, can be closed with a seal.

During the cyclical displacement of the rotating element 12 in the direction of the arrow 17 , the horizontally oriented pickup 18 loaded with the bag 25 is pivoted clockwise from the end of the feed conveyor belt 22 , and a bag received therein then assumes the position as it passes through the bag 26 is shown.

A guide plate 34 , which extends from the end side of the feed conveyor belt 22 downwards, ensures that the bag 26 cannot fall out of the corresponding sensor 18 . After a further cyclical displacement of the circulating element 12 , a bag is in the position as represented by the bag 27 .

In this position, the bag 27 is approximately vertical, with the bulge on the bottom at the top. The now upper end, which corresponds to the bottom 50 of the bag transported by the belt 22 , is just below a stop rail 52 which runs between the strips 21 , 21 'of a sheet lying next to each other in the lateral direction (see also FIG. 3 ).

During a further pivoting movement of the rotating element 12 , a bag 28 is pushed onto the top of the plate 35 , which in the exemplary embodiment shown in FIG. 1 swings in the vertical direction, as indicated by an arrow 41 . Due to the oscillation or vibration movement of the plate 35 , the bag 28 is raised slightly until it hits the stop rail 52 , then falls back onto the plate 35 and is then raised again. During this shaking or vibrating movement, the material in the bags 28 , 29 , 30 , 31 guided over the plate 35 moves partly due to the inertia of the mass, partly due to the downward movement tendency due to the force of gravity, such that the material moves relative to the bag moved downward, the bulge narrowing and gradually the material in the bags, as shown in the sequence of bags 28 to 31 in section, evenly distributed.

The speed of rotation of the rotating element 12 , the amplitude and frequency of the vibrating plate 35 are matched to one another in such a way that, depending on the goods, a bag at the end of the plate 35 , ie in the illustration of FIG distributed, i.e. assumes equalized form.

If the revolving element 12 is moved by a further cycle step in the direction of arrow 17 , the equalized bag 31 is transported away from the oscillating plate 35 and falls over a chute 44 onto a discharge conveyor belt 46 , as indicated by an arrow 45 , and arises the discharge conveyor 46 to lie, as shown by the bag 32 .

The bag 32 comes to rest on the discharge conveyor belt 46 in such a way that it is directed in the conveying direction thereof, as shown by an arrow 47 , with the head 48 ahead. If the leading end of the bag were to be inserted directly into a packaging box, the bag 32 would be upside down in this box. This is sometimes not desirable because it is common in supermarkets, for example, to place the equalized bags in a box on a shelf. Then the printed text would be upside down and could only be read with difficulty.

If the bag is to be turned over, as indicated by broken lines in FIG. 1, a baffle plate 33 can be arranged below the pocket-shaped pick-up 18, which is just moved away from the plate 35 , and the falling bag 32 hits the head end 48 thereof. By the left in the presen- tation of Fig. 1 movement of the transducer 18 , from which the bag 32 falls, he is given a tendency that he, as indicated in Fig. 1 by the arrow 45 ', with the bottom end 50 ahead, so turned on the Abführför derband 46 falls. It is thus possible, by simple measures, to optionally remove the bags from one end or the other from the device 10 according to the invention.

In Fig. 3 the effect of equalization is shown with respect to the stack height of bags.

Three bags 24 , 25 and 26 , which are stacked laterally before leveling, take up a much wider space than the three bags 24 e, 25 e and 26 e (e = equalized). From Fig. 2 it can be seen that, for example, four equalized bags approximately occupy the space in the direction Licher, as three non-equalized bags.

In Fig. 4 a modification of the device of Fig. 1 and 3 is shown, in which the circumferential element 62 is formed such that its pocket-shaped transducer 68 transport a bag 70 lying on the side over a plate 75 set in vibration.

The plate 75 is, as indicated by a double arrow 76 , 76 'in Fig. 4, in two spatial directions in vibration ver, ie the bag is set horizontally and horizontally in vibration, vibrated or vibrated. Equalization also takes place here, during which the circumferential element 62 transports a bag 70 to be leveled in the direction of an arrow 63 over the vibrating plate 75 .

In this case, the material 71 received in the bulky bag 70 filled with an uneven thickness is distributed in the horizontal direction, and brought into an equalized form by superimposing the vertical vibration component in cooperation with gravity, as shown in FIG. 4 by the product 71 '.

Here, too, a stop rail 52 'can be provided, which limits a movement of the bag in the illustration of FIG. 4 upward, away from the oscillating plate 75 .

Since there is a reduction in the height of the bag lying on the side during a leveling process in the embodiment of FIG. 4, the stop rail 52 'can be inclined, as is indicated in FIG. 4 by a dash-dotted line.

In a further exemplary embodiment of a device 80 according to the invention shown in FIG. 5, in which bags 104 to 109 are transported upright in the same way as in the device 10 of FIGS. 1 and 3, means 81 for receiving and transporting the bags 104 to 109 are provided provided, which contain a circumferential element 82 , which has a vertical axis 84 or a vertical journal, from which radially eight plates 85 protrude by 45 ° each. The circumferential element 82 thus has a star-shaped structure in plan view, as shown in FIG. 5, in which a pocket-shaped pickup 88 is formed in each case between two metal sheets 85 . Unevenly thick filled bags 104 are placed on a feed conveyor 92 , as indicated by an arrow 93 , standing with the thick bulge upwards, into a pocket-shaped pick-up 88 . The bags 104 and 105 rest on a stationary base plate and are moved clockwise by the action of the metal sheets 35 of the rotating element 82 , as indicated by an arrow 83 . After a rotary movement of approximately 90 °, a bag 106 is pushed onto means 86 which, like the means described above in connection with FIGS. 1 to 4, have a plate 87 which vibrate the bags in the vertical direction, ie in enable the representation of FIG. directed towards the viewer and away from 5 to move. In the meantime, the bags 106 , 107 , 108 and 109 are guided in a semicircular movement over the vibrating plate 87 , an equalization takes place, as is shown in FIG. 1 by the sequence of the bags 28 to 31 .

A bag 109 equalized after passing through this semicircular movement then falls via a chute 95 onto a discharge conveyor belt 96 and is then, as shown in FIG. 5 with the aid of an equalized bag 110 lying on the side, in the direction of an arrow 97 from the device 80 dissipated again.

Also, in the apparatus of FIG. 5, a turn may of course equally as described in connection with the baffle plate 33 of the embodiment of Fig. 1, an equalized bag are attained and can be advantage so that it transported away with either the head end or the bottom end first, .

In the embodiment of FIG. 5, a stop rail can again be provided, which limits an upward movement of the bags 106 to 109 away from the vibration plate 87 .

A guide wall 90 ensures that the bags 105 to 109 moving in a circle do not move radially away from the corresponding pocket-shaped receptacles 88 .

Also in the device 80 of FIG. 5, there is a coupling, not shown here, of the control of the rotating element 82 and the control of the feed conveyor belt 92 , which ensures that a bag 104 can only be inserted into a pocket-shaped receiver 88 if such was pivoted in front of the discharge end of the feed conveyor 92 . Here, too, it is possible to work in increments, it is also possible to drive with a continuously rotating mode of operation.
