Description

The invention relates to a palletizer for palletizing goods, in particular unfilled paper sack packages, on a pallet, comprising at least a feed belt for feeding the goods to be palletized to a laying belt, an adjustable length belt for placing and delivering the goods onto a lamination belt unit, and a lamination belt unit Delivery of the goods to be palletized on a pallet with at least one length-adjustable stratification belt, which is set up so that stored goods fall on the pallet.

Such palletizers are known in the art. Thus, the patent application discloses DE 19 501 637 A1 a palletizing device, in particular for stacks of empty packaging or packaging blanks, with a height-adjustable pallet. By means of various conveyor belts, goods to be palletized are positioned in such a device in a desired laying pattern on a so-called stratification belt unit. The goods to be palletized are fed from a freight flow direction. Upon completion of the pattern to be laid out of goods to be palletized, by means of the stratification belt unit a delivery of the laid pattern onto a pallet is effected.

A disadvantage of the described prior art has the effect that the palletizing capacity is limited with respect to the palletizable goods per unit of time, in particular by the unilateral goods supply. This is particularly due to the fact that the conveyor speeds of the belts and also the retraction and extension speeds of the belts are limited.

Another disadvantage arises in particular when a pallet change is to be made, because an introduced into the machine range has reached the desired level. In such a case - which makes it necessary to change the pallet - the flow of material or goods to the palletizing device must be interrupted.

This makes it necessary for the upstream production units to temporarily discontinue production, which results in significant efficiency disadvantages and increased staff costs.

It is therefore the object of the present invention to provide a palletizing device while avoiding at least some disadvantages of the prior art, in particular to provide a palletizing device which increases the palletizing speed and thus the overall achievable product output of a production device. Moreover, it is an object of the invention to provide a palletizer capable of continuously receiving goods to be palletized.

According to the invention the object is achieved in a Pealletiervorrichtung of the type mentioned by a second feed belt for feeding further goods to be palletized to a second delivery belt, and a second length-adjustable belt for the arrangement and delivery of goods on a stratification belt unit.

Such a palletizing device according to the invention has the particular advantage that the number of goods to be palleted per unit of time is significantly increased by means of such a device according to the invention. A given laying pattern can thus be laid in a significantly shorter period of time, or built up and delivered to a pallet.

The palletizer according to the invention also brings significant cost advantages. If one considers, for example, a production line whose output exceeds the palletizing capacity of a palletizing device known in the prior art, it would be necessary according to the prior art to provide a second palletizing device. With the palletizer according to the invention, it is now possible to palletize a significantly larger number of goods per unit time, which in the case described, the use of a single palletizer of the type according to the invention is sufficient.

This can also generate synergy effects, since individual device components are provided only once. This results in a significant cost savings.

Another particular advantage of using a palletizing device according to the invention over the alternative of using, for example, two palletizing devices, as are known in the prior art, moreover arises in relation to the required installation space or positioning space. Thus, an existing production floor area can be used and utilized more efficiently and in a more space-saving manner by means of the palletizing device according to the invention. Overall, this aspect allows a further reduction of the total manufacturing fixed costs. It is further to be expected that the use of a palletizer according to the invention over the use of two known in the art palletizing at a given palletizing per unit time requires less labor, less maintenance costs and lower energy consumption, and less complex, in particular because of the smaller number of components used, is.

According to another aspect of the invention, the object is further achieved in a palletizing device of the type mentioned above by at least one bypass device for dividing a goods flow from goods to be palletized and for providing the goods to be palletized on the laying belt and / or the second laying belt.

The bypass device advantageously allows the division of the flow of goods, so that in a confined space and on a small footprint, the supply of goods to be palletized in the palletizing from different directions - at least on different bands - can be done.

The bypass device is also advantageous to influence the flow of goods towards the palletizer. For example, it is conceivable to easily delay the flow of goods and / or to temporarily store a certain number of goods during a pallet change, so that the production process does not have to be interrupted. This has the advantage that the production can run without interruption and significantly more efficient, thereby saving costs overall.

Furthermore, the palletizer according to a preferred embodiment, characterized in that it comprises a machine frame having a longitudinal axis and the at least one bypass device at least one vertical bypass, substantially above the machine frame extending, and / or at least one horizontal bypass, substantially laterally and / or parallel to Machine frame longitudinal axis running, has.

Depending on the available space and the nature of the production or manufacturing area so that the divided goods flow can be performed advantageous and flexible. Thus, for example, a space-saving freight management above the machine base body is conceivable, but it is also possible to guide the goods flow laterally, preferably parallel to the main body or machine frame longitudinal axis. It should be noted at this point that the variations described here are merely examples that do not represent an exhaustive list. All possible implementations which are found to be particularly advantageous by a person skilled in the art are possible in principle and belong to the invention.

Furthermore, it is preferred that the vertical bypass comprises conveying elements, in particular at least one vertical switch or at least one intermediate belt and / or at least one vertical parallel belt. The formation of a bypass by means of said conveying elements has the advantage that the goods flow can be performed flexibly. For example, this makes continuous material transport just as possible as intermittent freight transport. On the intermediate belt or the parallel belt goods can be temporarily stored and supplied to the Pallettiervorrichtung if necessary, for example, even if the production of goods upstream is temporarily interrupted, such as due to a business interruption. The palletizing by means of the palletizing device can be continued for a while using the stored goods in any case.

Further preferably, the horizontal bypass on several conveyor elements, in particular at least one horizontal switch and / or at least one sideband and / or at least one horizontal parallel band. Again, there is the advantage - a flexible freight management, adapted to the respective space conditions. Once again, a continuous, intermittent, or provided with further operating modes freight transport is possible.

According to a further preferred embodiment, the palletizer has at least one horizontal bypass on a machine frame longitudinal axis side of the machine frame. Preferably, the horizontal bypass is designed to extend substantially parallel to the machine frame longitudinal axis. The existing production area can be optimally utilized. In addition, the result, for example, of a parallel arrangement of several horizontal bypasses has the advantage that a horizontal bypass can be used for buffering goods, so that in the event that a pallet is to be changed, efficient buffering can take place so that the production process as a whole is not interrupted is. By arranging a desired number of bypasses, it is possible to respond specifically to the prevailing production reality and to achieve a tailor-made and particularly advantageous solution with special consideration of the production volume.

According to a preferred development, the palletizing device has in each case at least one horizontal bypass on both sides of the machine frame. With regard to the particular advantages, reference is made to the above statements. In principle, such an arrangement again enables a good utilization of the available production space and an individual adaptation of the freight transport and the goods buffering with regard to the present production volume.

Furthermore, the at least one bypass device for receiving and temporarily storing goods, in particular on the at least one intermediate belt and / or the at least one parallel belt, is set up. This results in the already mentioned advantage that a production process, in the case of the use of processes tailored to this process Bypass facilities with memory function can run substantially uninterrupted. Events, such as a pallet change or a short-term malfunction in the palletizing, now not necessarily lead to a production interruption. This results in a clear overall efficiency gain.

Further preferably, the palletizer has at least one centering device for centering the goods to be palletized on the second feed belt.

This results in the advantage of an exact centering of the goods to be palletized, so that a standardized transfer characteristic results for the next process step. If individual goods have been displaced during the transport process, for example, then the goods are exactly centered on the conveyor after passing through the centering device and can be taken over in a next step with standardized positioning.

Furthermore, according to a preferred embodiment, the palletizing device has at least one turning device for rotating the goods to be palletised on the second feeding belt. This results in the particular advantage that the goods to be palletized particularly space-saving or particularly stability-giving, with regard to the pattern to be laid, can be aligned. Thus, it is particularly advantageous possible to increase the number of goods to be palletized by optimizing the alignment.

According to a preferred development, the palletizing device moreover has at least one slider device for aligning the goods to be palletized, substantially perpendicular to the transport direction, on the second conveyor belt. Again, the particular advantage results from the fact that an optimized pattern with respect to the goods to be deposited can be formed. In this way, for example, the intake of goods to be palletised on a given pallet can be optimized and maximized, but it is also possible to achieve the highest possible stability by means of a certain laying pattern, for example against overturning of the palletized goods.

Another alternative preferred embodiment is characterized in that the palletizing device has a device for pallet supply and / or for pallet removal and / or for height adjustment of pallets. This has the advantage that the palletizing process can be further automated and optimized, so that the pallet change times can be significantly reduced compared to a manual pallet change. This results directly in an increase in Gesamtpalettierleistung per unit time, and thus an efficiency and cost advantage.

Further preferably, the bands of the palletizing device, in particular the feed belts, laying belts and the at least one stratification belt, have electrical drives with linear motors. As a result, this makes it possible to realize precise belt movements which enable an optimized palletizing of goods without jeopardizing, for example, existing laying patterns due to jerky and uncoordinated movements with regard to laying precision. In addition, such drives are robust, and easy to maintain, for example, compared to belt drives.

According to the invention, the object is also achieved by a system for producing and packaging sacks, in particular paper sacks, at least comprising a bottoming machine for bag production, a conveyor for receiving the bags, in particular from the floor laying machine and for forming at least two streams of goods from the recorded bags and a palletizer for palletizing the introduced in the form of at least two streams of goods in the palletizing bags. Such a system results in the advantages of increasing the efficiency of the invention by increasing the number of goods to be palleted per unit of time. With regard to the other advantages, reference is made to the arguments already given.

It is further preferred that the palletizer is a palletizer as described above. In that regard, reference should also be made here to the advantages already mentioned.

According to the invention, the object is further achieved by a method for palletizing goods, in particular paper sacks, comprising at least the steps of providing goods, in particular paper bags, by means of a first and a second feed belt, conveying a respective first and second goods to a first and a second laying belt, moving the first laying belt and the second laying belt into the desired position by adjusting the length and dropping the goods onto a lamination belt unit, moving the belts of the lamination belt unit through Length adjustment to the outside and dropping the goods on the pallet.

The implementation of such a method again allows a significant increase in the number of goods to be palleted per unit of time.

It is further preferred that the palletizing device used to carry out the above-mentioned method is a palletizing device according to the invention, as already introduced and described above. In that regard, the advantages already mentioned at this point arise analogously.

According to a preferred development, the method additionally comprises the steps of: centering in each case a good, in particular a paper bag package, on the first and / or the second feed belt, rotating respectively one good, in particular one paper bag package, on the first and / or the second Feed belt, positioning each one good, in particular a paper bag package, substantially perpendicular to the transport direction on the first and / or the second feed belt.

Carrying out the method steps described brings with it the additional advantage that goods which may possibly be arranged on the conveyor belts by the transport process in almost any desired manner are brought into a defined orientation. By rotating the goods and moving them sideways, it is also possible to prepare any laying pattern by these steps. As a result, the paletable amount of goods per pallet is increased, or it can also be realized other advantages, such as a particularly optimized lapping, for example, with regard to the stability of the palletized goods.

Another alternative preferred embodiment is characterized in that the palletizer of the above-mentioned method is a palletizer, as has already been introduced in this description. In that regard, reference is again made to the statements already made with regard to the advantages.

1 shows components of a production line for the production and palletizing of paper sacks 2 , A floor laying machine 4 serves the training of paper sacks. In a Press belt unit 6 with different press belts 7 a pressing of the paper bags takes place. A sack package forming unit 8th serves the formation of lots. Subsequently arranged in Gutflussrichtung is a palletizer 10 , The palletizer has a machine frame 12 on. The palletizer 10 has a height-adjustable pallet guide 14 on. Pallets can be transported via a pallet feeder 16 be fed and a pallet removal 18 be dissipated.

A feeding belt 20 serves the supply of goods to be palletized. In the area of the feed belt 20 there is a vertical switch 22 , which allows a splitting of the goods to be palletized and part of a bypass device 28 is, which is further explained below. The feeding belt 20 downstream in Gutflussrichtung is a centering device 36 , which is a material to be palletized, such as by the reference numeral 26 indicated on the conveyor belt 20 centered.

A turning device 38 is the centering device 36 downstream. The turning device 38 allows a rotation, respectively an orientation of a good to be palleted, for example, the goods 26 , The turning device 38 downstream is a slider device 40 , The slider device 40 allows slides with an alignment of a palletized good 26 perpendicular to the crop flow direction.

Palettierbänder 44 are the slider device 40 downstream. For detailed information on these palletizing belts 44 be on the 4 ff. referenced.

bypass device 28 includes the vertical switch 22 that divides the goods flow. The vertical switch 22 is an intermediate band 24 downstream, which goods to be palletized on a vertical parallel band 30 leads. This downstream is again an intermediate band 24 and a vertical switch 22 , The vertical switch 22 leads to palletizing goods on a second conveyor belt 34 .The individual bands, especially the intermediate bands 24 , the vertical parallel band 30 as well as the vertical switches 22 form essential parts of the bypass device 28 ,

At the second feed belt 34 is a second centering device 50 arranged, which is a centering of the supplied goods - shown here is an exemplary, second to be palletized Good 32 - serves. Subordinate in the second transport or feed direction is a second rotating device 48 for rotation of the goods to be palletized 32 on the second feed belt 34 , Downstream of this is a second slider device 46 for aligning the goods perpendicular to the transport direction. Subsequently, the goods are also from this second feed the palletizing belts 44 supplied, wherein respect to the principle of operation and a detailing of the same 4 ff. again referenced.

2 shows a plan view of already out 1 known components. In addition to 1 is in 2 a machine frame longitudinal axis 41 drawn up and introduced, which will be referred to later.

The enlarged view of the palletizer with vertical bypass in Fig. 3, some additional components can be removed. Thus, the feed belt has a linear motor drive 42 , It should be noted that the linear motor drive 42 here only for the feed belt 20 is shown, in principle, however, can be transmitted analogously to all other tape units. Furthermore, the height-adjustable pallet guide 14 detail. It has a pallet guide drive 56 on to the height adjustment of pallets 68 (see. 4 ) serves.

4 Now can the arrangement of Pallettierbänder 44 and their interaction are taken. Referring first to the side view, the feeding belt 20 serves to feed goods to be palletized. As an example, here is the good B, which is denoted by the reference numeral 26 is provided, shown. The feeding belt 20 downstream is a laying band 58 , The band 58 allows a transport of goods, but it is also adjustable in length and can be moved in the transport direction and against the transport direction.

The band 58 downstream is the stratification belt unit 62 , The stratification belt unit 62 has a first layering band 64 and a second layering band 66 on.

According to the illustrated side view is below the stratification belt unit 62 the height-adjustable pallet guide 14 with the pallet lying on top 68 shown. Depending on the level of the pallet 68 It is the task of the height-adjustable pallet guide 14 , the palette 68 in an optimum distance for palletizing the stratification belt unit 62 respectively.

Furthermore, the palletizing belts 44 a second feed belt 34 on. From this conveyor belt 34 goods are - exemplified here is the good A with the reference number 32 , which is already on a second band 60 is - fed.

In Gutflussrichtung based on the estate 32 is located after the second feed belt 34, the second laying belt 60 , The second band 60 can on the one hand to transport goods in a conventional manner, however, is also adapted to be moved in and out in the transport direction against the transport direction. This makes it possible, a good, such as the good 32 Store on a desired position on the stratification belt unit.

In the lower part of 4 the section of the palletizer is shown in a plan view. Such a display mode, namely the representation of a side view in the upper part of the figure and a plan view in the lower part of the figure, is for the following 5 - 10 maintained in an analogous manner.

Coming back to 4 is first in the lower part of the figure, the feed belt 20 shown. On the conveyor belt 20 there is a good to be palletized 26 , It can also be seen that the laying belt 58 which is the feed belt 20 is downstream, is in a partially retracted state.

The second feed belt 34 is in a known manner, the second belt 60 downstream. The second band 60 is in one compared to the laying belt 58 extended state. The good 32 , which is arranged on the second laying belt, is located in the position shown above the stratification belt unit 62 ,

With the help of - Now the palletizing process using the palletizing device will be detailed. The already described and introduced components can the 5 - 10 analogous to 4 be removed. New reference numbers only result for newly introduced into the process, or the process, to be palletized goods.

As 5 can be removed, was the good A by the reference numeral 32 by returning the second band 60 delivered to the stratification belt unit. On the second feed belt 34 there is already another good C with reference numerals 70 , The good 26 is still on the conveyor belt 20 , It should be noted that the tape opposite 4 is now in a clearly extended in the transport direction state.

The lower part of the 5 can be seen that the good C with reference numerals 70 is in a different orientation transverse to the transport direction compared to the goods 26 and 32 , In addition, is good 70 opposite the goods 26 and 32 rotated by 90 degrees. These operations are in an earlier process step with the already introduced centering device 36 , Rotary device 38 , Slider device 40 or the second centering device 50 the second rotating device 48 and the second slider device 46 realized.

In 6 now became the estate 26 on the band 58 convicted, and the laying tape 58 even compared to the step shown in 5 continue to proceed in the transport direction. The good 26 is now in a position just before dropping onto the stratification belt unit 62 , Good C with reference number 70 is still on the second feed belt 34 , The second band 60 but was opposite 4 retracted further.

In 7 is the discharge operation of the goods B with reference numerals 26 from the laying belt 58. The band 58 will be under the estate 26 retracted against the transport direction. This drops the estate 26 on the stratification belt unit 62 , On the conveyor belt 20 is already a new good D with reference numerals 72 fed. Good C with reference number 70 is still on the second feed belt 34 , The second band 60 is now extended in the transport direction.

In 8th is now the good D with reference numerals 72 seen substantially in the transport direction at the end of the feed belt 20 been transported. laying belt 58 is located in one opposite 7 retracted state. Good B with reference number 26 is now on the stratification belt unit. The discharge process is thus completed.

Good C with the reference 70 is now on the second band 60 passed over, with the second band 60 across from 7 is clearly extended in the transport direction to position the Good C in the transport direction relevant to the Good C above the stratification belt unit.

In 9 becomes the second band 60 Now back process, which the good C with the reference 70 is delivered to the Legebandeinheit. The estate D with the reference number 72 is opposite 8th at unchanged position. About the second feed belt 34 now becomes a good E with the reference numeral 74 fed.

By way of example, it is assumed at this point that the arrangement of the goods A, B and C on the stratification belt unit corresponds to the desired laying pattern.

As in 10 Now you can see the bands of the stratification band unit 62 namely the first layering band 64 and the second layering band 66 , in each case moved outwards. Thus, the goods A, B and C according to the previously created laying pattern on the pallet 68 issued.

After delivering the goods A, B and C to the pallet 68 Now takes place by means of the height-adjustable pallet guide 14 a lowering of the pallet 68 , Subsequently, the first stratification band 64 and the second layering band 66 inside, which again results in a shelf space. On the storage surface of the stratification belt unit 62 Now a new pattern of goods can be built and finally to the pallet 68 be delivered.

The laying pattern shown here as well as the orientation of the goods A, B and C are explicitly shown here only as an example. Also, it is not necessary that the goods to be palletized have the same size.

In 11 an example of a palletizer according to the invention is shown, which instead of the vertical bypass device 28 a horizontal bypass, which in the form of various embodiments in the 12 - 14 is detailed. The actual, in 11 illustrated palletizer 76 , follows the known procedure for the palletizing process itself. The illustrated reference numerals have already been introduced and described.

12 shows the top view of a palletizer 76 , which have a horizontal bypass 84 which is on one side of the machine frame longitudinal axis 41 is arranged. The horizontal bypass 84 has horizontal switches 78 , Side walls 80 and a horizontal parallel band 82 on.

The horizontal switch 78 essentially serves to divide the flow of goods. A first part of the goods flow passes over the conveyor belt 20 in the centering device 36 and then passes in a known manner to the palletizing belts 44 ,

A second part of the freight flow is from the horizontal switch 78 led to the sideband 80. The goods in question are then conveyed to the horizontal parallel belt 82. From there the goods pass over another sideband 80 to a second feed belt 34 , From there, these goods arrive in a manner known per se to the palletizing belts 44 and thus justify the second feed direction.

At this point it should be noted that an opposite goods feeder, as in 12 and was also shown in the preceding embodiments, is particularly advantageous, but the invention is not limited to such an arrangement of the goods feed. Rather, it is up to the skilled person to devise a solution that deviates from an opposing arrangement.

An alternative embodiment of a horizontal bypass 86 is in 13 shown. This horizontal bypass 86 is parallel to the machine frame longitudinal axis on both sides 41 arranged. He has two horizontal switches 78 putting it on the conveyor belt 20 incoming goods flow either unaffected in the direction of the centering device 36 let pass, or this in the direction of the sidebands 80 redirect. From there, the goods reach the downstream horizontal parallel belts 32 and by means of sidebands 80 to the second feed belt 34 , For example, it is at the in 13 illustrated arrangement possible to use one of the two bypasses for temporary storage of goods. So it would be possible to cache a certain amount of goods without being palletized directly.

This applies in principle also for in 14 illustrated embodiment with a horizontal double bypass 88 , Here are both bypasses 88 on one side parallel to the machine frame longitudinal axis 41 , The horizontal double bypass consists of two horizontal switches 78 , a total of four sidebands 80 as well as two horizontal parallel bands 82 ,

By means of a first horizontal switch 78 the flow of goods which is supplied via the feed belt 20 is divided. This separated goods flow now reaches the sideband 80. In this crop flow direction behind the sideband 80 a switch 90 is arranged. This divides the flow of goods again in the direction of the parallel band 82 or over the sideband 80 in the direction of the parallel band 92. After passing the parallel bands 82 , or 92 the goods become by means of the sidebands 80 merged and finally arrive at the second Zuführband 34 , Also, such an arrangement allows, as already stated, a temporary caching of goods.
