Description

The present invention relates to a method and a device for packaging and sealing small products such as chocolate pieces, stock cubes or stock tablets, hard caramels, soft caramels, washing machine or dishwasher tabs.

There are intermittent packaging machines for wrapping stock cubes and tablets. Outputs of up to 2000 products / minute can be achieved here. However, due to the extremely short cycle times (60 ms), this places very high dynamic demands on the working organs and leads to increased product loads due to impact and impact processes, since the respective processing step takes place within a product rest (35 - 40 ms).

This output can hardly be increased, or only with considerable additional effort, since the growing dynamic loads can no longer be sufficiently compensated for by, for example, lightweight construction measures. The susceptibility of the process to product tolerances also remains problematic.

At present, only very limited product tolerances can be processed in this high speed range. Another disadvantage is the high noise level that clocked machines are already emitting, and which would increase with increasing output or would have to be shielded even more elaborately.

A proven alternative to intermittent work is known from other areas such as chocolate, toffee and hard candy. By using a continuous working principle, the processing times are significantly extended, since the respective processing step is stretched over several working cycles, in that the product to be processed is in constant motion without intermediate stops. The processing operations take place during the movement.

the EP 2 906 473 or. WO 2014/056589 discloses a continuously operating, multi-lane packaging machine for small-sized products.

Another two-lane, continuous packaging machine for bouillon cubes is from the EP 2 894 103 famous. With this packaging machine, the products are fed in pairs on two lanes at the same time, continuously positioned in pairs and synchronized, with a first single wheel (pick-up wheel) continuously picking up products from both lanes and packaging material (one section per lane) being fed to the first wheel. A second single wheel (packaging wheel) for both lanes creates the wrapping of each individual product per lane from the packaging material. A third single wheel (tilting wheel) for both lanes transfers the products at the exit to an encapsulation module, in which further folding processes and an encapsulation (sealing) of the products on both lanes are carried out.

The present invention is based on the object of improving the known methods and devices for packaging and sealing small-sized products in order to achieve processing of the products that is as gentle on the product as possible with the highest possible packaging performance or output.

To achieve this object, the invention provides the method according to claim 1 and the device according to claim 6.

A first aspect of the invention relates to a method for packing and sealing small-sized products on three continuously rotating working heads, each product on the first working head being assigned a packaging material, each product with assigned packaging material being subsequently transferred to the second working head on which the product is placed is packed by folding the assigned packaging around the product, each packaged product then being transferred to the third working head, on which the packaging assigned to each product is sealed. In this method, the folding and packaging processes are largely or completely carried out on the first two working heads, while the final third working head is preferably used exclusively for sealing the packaging. Each working head preferably comprises the same number of working elements (e.g. pairs of gripper jaws) and / or rotates at the same angular speed around its axis of rotation. The packaging means assigned to the product is preferably sealed on the third working head on at least two sides of the product, preferably on two sides of the product facing away from one another, particularly preferably on the two end faces of the product. The product is preferably already packaged ready on the second working head by folding the assigned packaging around the product, but at the latest on the third working head.

With the use of the continuous working principle on three rotating working heads, a significant increase in the output of a packaging machine can be achieved, especially for pressure-sensitive products such as bouillon cubes and tablets. At the same time, the product load, which is very important for these sensitive products, be lowered and brought within permissible limits. In addition, larger product tolerances can be processed at high speed. The method according to the invention ensures an optimal product flow through the packaging machine, taking into account contamination processes and thermal processes. The complexity is limited to three continuously rotating working heads before the products are transferred to a delivery belt, for example. The essential processing steps necessary for packaging are implemented in these three heads.

In order to solve problems of accessibility, especially when there are several lanes, all the heads are preferably cantilevered in a frame arranged at the rear.

The packaging machine according to the invention enables an output of up to 3000 pieces per minute, particularly in the configuration for bouillon cubes and tablets.

Advantageous further developments of the invention are the subject matter of the dependent claims.

It can make sense if the products on the three continuously rotating rotary heads are packed in multiple lanes on parallel product lanes. This allows the packaging performance of the method according to the invention to be increased further. A multi-lane packaging machine is from the EP 2 906 473 known, the contents of which are incorporated herein by reference.

It can prove useful if the packaging assigned to each product is sealed on the third working head on the side and possibly on the product base, preferably with the working organ holding the product, the working organ preferably turning the product by at least one full turn of the third working head Holds the axis of rotation, the working member being particularly preferably heated by means of induction, very particularly preferably being heated in a state in which the working member is not holding any product. Corresponding seal heads are from the DE 10 2018 209 185.4 and DE 10 2019 210 354.5 known, the contents of which are incorporated herein by reference. With a suitable sealing head, the sealing time can be extended to such an extent that the sealing can take place within the continuous movement of the rotary head. The packaging material assigned to the product is preferably sealed from the side on the two end faces of the product.

It can be advantageous if the product transfer between the first working head and the second working head and / or the product transfer between the second working head and the third working head takes place exactly or essentially in a tangential direction to the axes of rotation of the respective working heads. This avoids rapid changes in direction and quality-reducing lateral accelerations of the product perpendicular to the direction of movement.

Dadurch sind die (mit Flächennormalen in und entgegen der Bewegungsrichtung bzw. tangential zum Teilkreis ausgerichteten) vorderen und hinteren sowie (mit Flächennormalen radial zur Rotationsachse des Arbeitskopfs nach innen und nach außen ausgerichteten) oberen und unteren Seitenflächen des Produkts zur Umwicklung mit Packmittel zugänglich. Das Halten des Produkts erfolgt vorzugsweise über ein Arbeitsorgan bzw. Greiferbackenpaar, welches das Produkt zwischen dessen Stirnseiten einklemmt.
• - Schritt B: Zuordnen eines Packmittels zu dem Produkt. Die Zuführung des Packmittels zu dem Produkt erfolgt vorzugsweise von der Vorderseite des Produkts, d.h. der in Bewegungsrichtung führenden Seite des Produkts, sodass das Produkt quasi in das bereitgestellte Packmittel „hineinläuft“ und selbiges in der Bewegung entlang der Bewegungsrichtung mitnimmt. Das Packmittel wird vorzugsweise mit einer Packmittelzange in Anlage am Produkt gehalten.

However, it can also be practical if the packaging of the product with packaging material has at least one of the following steps, of which steps A to D are preferably in the specified order, preferably on the first working head, and / or steps E to J are preferably in in the specified order, preferably on the second working head:

• - Step A: Holding the product across the width or between its front sides. As a result, the front and rear (aligned with surface normals in and against the direction of movement or tangentially to the pitch circle) as well as (with surface normals radially inward and outward to the axis of rotation of the working head) upper and lower side surfaces of the product are accessible for wrapping with packaging material. The product is preferably held by a working element or pair of gripper jaws, which clamp the product between its end faces.
• - Step B: Assigning a packaging to the product. The packaging material is preferably fed to the product from the front of the product, ie the side of the product leading in the direction of movement, so that the product “runs” into the provided packaging material and takes the same with it when it moves along the direction of movement. The packaging is preferably held in contact with the product with packaging tongs.
• - Step C: Arranging the packaging in an L-shape around the product. The L-shape of the packaging means preferably covers the front and lower or the side surfaces of the product which lead in the direction of movement and which are oriented radially outward.
• - Step D: Arranging the packaging in a U-shape around the product. The U-shape of the packaging means preferably covers the front, the lower and the rear or the in and against the direction of movement as well as the radially outwardly oriented side surfaces of the product. In this state, the product is preferably transferred to the downstream working head.
• Step E: Holding the product and the packaging means assigned to the product over the length so that the end faces of the product are exposed, and / or placing a leg of the U-shaped packaging means against the Product. The length of the product and the packaging associated with the product is preferably held by a working element or pair of gripper jaws, which clamps the product and the packaging associated with the product over the length, ie over the product axis aligned along the direction of movement or tangential to the pitch circle.
• Step F: Forming a first forehead inner fold from the packaging means protruding over each end face of the product and folding the same onto the end face of the product. The order of steps F and G can be swapped.
• - Step G: Arranging the packaging in the form of a tube around the product. As a result, the packaging is closed around the circumference of the product in a plane oriented perpendicular to the axis of rotation of the rotary head.
• Step H: Forming a second forehead inner fold from the packaging material protruding over each end face of the product and folding it onto the end face of the product. Ideally, the packaging material overhang is selected in such a way that a small section of the end face of the product is still exposed between the first and second front inner folds. The order of steps H and I can be swapped.
• Step I: Forming a first outer forehead crease from the packaging material protruding beyond each end of the product and folding the same onto the first and optionally second inner forehead crease on each end of the product.
• Step J: Forming a second forehead outer fold from the packaging material protruding beyond each end face of the product and folding it onto the first and second forehead inner fold and the first forehead outer fold on each end face of the product.

Steps F to J are preferably carried out simultaneously on both end faces of the product, preferably symmetrically to the center of the product. In the case of rectangular end faces, the packaging material overhang is preferably chosen to be so large that there is a secure overlap of the two front outer folds. In the case of a square end face, these folds will preferably only butt against one another or overlap each other to a minimum, the overlap not being able to be significantly increased. In the exemplary embodiment described - when the products are transferred from the second to the third working head with sufficient coverage of the last two folds - the sequence of steps F-G-I-H-J should preferably be used. The first and last folds are preferably connected to one another in order to fix the packaging in the folded state.

The first and / or second forehead inner fold (s) is / are preferably folded over one of the two shorter side edges of a rectangular end face of the product.

The first and / or second front outer fold (s) is / are preferably folded over one of the two longer side edges of a rectangular end face of the product.

• - Einen ersten Arbeitskopf, welcher ausgebildet ist, um kontinuierlich rotierend jedem Produkt ein Packmittel zuzuordnen.
• - Einen zweiten Arbeitskopf, welcher ausgebildet ist, um kontinuierlich rotierend jedes Produkt mit zugeordnetem Packmittel vom ersten Arbeitskopf zu übernehmen und das Produkt durch Faltung des zugeordneten Packmittels um das Produkt zu verpacken.
• - Einen dritten Arbeitskopf, welcher ausgebildet ist, um kontinuierlich rotierend jedes verpackte Produkt vom zweiten Arbeitskopf zu übernehmen und das jedem Produkt zugeordnete Packmittel zu siegeln.

Another aspect of the present invention relates to a device for packaging and sealing small-sized products on three continuously rotating working heads, comprising:

• - A first working head, which is designed to assign a packaging means to each product in a continuously rotating manner.
• - A second working head, which is designed to take over continuously rotating each product with assigned packaging means from the first working head and to pack the product by folding the assigned packaging means around the product.
• - A third working head, which is designed to take over each packaged product in a continuously rotating manner from the second working head and to seal the packaging material assigned to each product.

The same advantages result that were mentioned above in connection with the method according to the invention.

The second working head and / or the third working head is / are preferably designed to finish packing each product by folding the associated packaging material around the product.

The third working head is preferably designed to seal the packaging means assigned to each product on at least two sides of the product, preferably on two sides of the product facing away from one another, particularly preferably on the two end faces of the product.

It can be useful if the device has a product feed in order to feed the products to the first working head, preferably tangentially to its pitch circle, preferably on a plurality of parallel product paths. As a result, the products are optimally positioned for the subsequent product pick-up by the first working head. All products to be picked up are preferably positioned and oriented in the same way with respect to the respective working organ of the first working head at the picking up station. As a result, a uniform packaging result can be achieved for each product.

It can prove to be practical if the device has a product dispenser in order to remove the products from the third working head, preferably exactly or essentially tangentially to its pitch circle. As a result, the products are ejected from the packaging device in a particularly gentle manner.

It can be helpful if the pitch circles of two or three of the working heads overlap when projecting in the vertical direction and / or in the horizontal direction. As a result, the design of the packaging device is particularly compact. The pitch circle generally describes the path on which the center of the product is guided around the axis of rotation of the working head. Alternatively, the pitch circle describes a circle around the axis of rotation of the product-guiding rotary head, which runs through the center of the product at the time of product pick-up and / or delivery.

However, it can also prove to be expedient if the axis of rotation of the third working head is arranged above the axis of rotation of the second working head and / or above the axis of rotation of the first working head. This means that the sealing station is at the top of the packaging process. The waste heat from the working organs rises upwards and therefore does not impair the first and second working heads lying underneath and the packaging processes carried out on them.

terms and definitions

The term “small-sized products” particularly refers to small-sized food products such as chocolate pieces, bouillon cubes or brewing tablets, hard caramels such as candies, soft caramels such as chewy candies, but also small-sized consumer goods such as washing machine or dishwasher tabs. The small-piece products preferably have a cuboid shape, in particular a cube shape, or at least a rectangular base area. However, it is also possible to pack other product forms using the method according to the invention.

The term “ready-packed” means that after all the folding processes have been completed, all side surfaces including the end faces of the product are covered with packaging material, and that preferably no further folding or packaging steps follow within the scope of the device and method according to the invention.

The product is preferably packaged airtight in the completely sealed state. The packaging is preferably made airtight and the overlapping packaging sections are sealed airtight. Length, width, height and sides of the product

The terms length, width and height of the product are usually defined in relation to its direction of movement.

Detailed Description of the Preferred Embodiments:

The invention is described below on the basis of the preferred exemplary embodiment with reference to the figures.

The packaging device comprises the implementation of a continuous packaging process 1 according to the preferred embodiment of the invention, a conveyor belt 2 as a product feed, a gripper head 3 as the first working head, a packing head arranged above it 4th as a second working head and a sealing head arranged above it 5 as a third working head as well as and a delivery belt 6th as a conveying device. In addition, the packaging device 1 an inductor 7th for inductive heating of the working elements of the sealing head 5 as well as a packaging material feed 8th on that of the gripper head 3 for each product P. a packaging material or a packaging blank V exactly or essentially radially to its pitch circle T3 or radial to the circular segment-shaped movement paths P1 , P2 of the products P. on the first working head 3 feeds.

The products P. are in constant motion across different stations without stopping S1-S11 through the packaging device 1 guided. This can be done with one, two or more lanes. The handover of the products P. from one to the next working head 3 , 4th , 5 takes place in the tangential direction in the respective product path P1 , P2 . The main features of the invention are in detail:

Product feed / conveyor 2

In the conveyor 2 a continuous product feed takes place in a regular product sequence, with the products in their position in relation to the following first working head or gripper head 3 be synchronized.

First working head - gripper head 3 (stations S1 to S5)

In the gripper head 3 the inclusion of individual products takes place P. by a working element, here by laterally arranged grippers, from the conveyor 2 in the tangential direction. The supply of a packaging material V can be carried out approximately in the radial direction, but also tangentially. The packaging V is next to the product to be packaged P. positioned (cf. 2 B) and fixed by means of packaging pliers (not shown). The packaging is then folded V to the bottom of the product P. (see. 2c ) by the products P. can optionally be guided past a guide curve (not shown).

Second working head - packing head 4th (Stations S5 to S10)

The packing head 4th takes over the products P. with assigned packaging V tangential in the movement of the gripper head 3 by a working element, thereby grippers arranged in the front and rear in the direction of movement. The complete folded cover is produced by forming a tubular envelope from the packaging material V as well as folding the overhang of the packaging material onto the front sides of the product in the in 2 illustrated views (d) to (j).

The packing head 4th has movable folding elements at each station (bottom folder, forehead folder), which realize the folding in connection with external folding elements (e.g. folding arches, folding switches, folding head).

Third working head - sealing head 5

The seal head 5 takes over the products P. tangential in the movement of the packing head 4th by a working element, thereby laterally arranged grippers in the direction of movement. The grippers or specially designed elements fix the (preferably lateral) folds by gripping. The grippers are heated so that the packaging material is sealed at the same time as it is gripped V he follows.

To extend the sealing time, the sealing head 5 alternatively, they can be designed in such a way that the products are held in the head for more than one turn and are accordingly sealed. A corresponding seal head 5 is in the German patent application DE 10 2019 210 354 , the contents of which are incorporated herein by reference.

• Nachdem die Produkte P versiegelt sind und damit die Faltung nicht wieder aufspringen kann, werden die Produkte P in tangentialer Richtung an eine kontinuierlich bewegte Abgabestrecke 6 übergeben. In der Abgabestrecke 6 können bei Bedarf weitere Funktionalitäten realisiert werden.
• Das können sein:
  • - Siegeleinrichtung für die Längsnaht
  • - Produktqualitätserfassung
  • - Ausschleusung fehlerhafter Produkte

Dispensing device 6th or delivery route 6th :

• After the products P. are sealed and so that the fold cannot open again, the products are P. in the tangential direction to a continuously moving delivery line 6th to hand over. In the submission line 6th further functionalities can be implemented if required.
• It can be:
  • - Sealing device for the longitudinal seam
  • - Product quality recording
  • - Rejection of defective products

Packaging feed 8

The packaging V is continuously unwound from a reel by a transport device. A cutting device separates individual packaging material sections V and transfers it to the gripper head 3 . A changing device is used to change from an empty to a full bobbin during unwinding in order not to interrupt the processing process. In the case of a two-lane or multi-lane design of the machine, longitudinal cutting into a corresponding number of packaging lanes and their deflection onto the respective product flow path are preferably carried out in the packaging material feed, so that two or more packaging material sections are then simultaneously carried out V to be provided.

It is essential that the functions mentioned in the two-lane design are performed in pairs at the same time for each lane P1 , P2 be carried out with multiple lanes P1 , P2 in a corresponding variety in parallelism.

The product flow is essentially from bottom to top and from a feed side to a discharge side that is away from it.

The core idea of the invention consists in the implementation of a packaging process with the highest output of up to 3000 prod./min. combined with justifiable demands on the processable product tolerances as well as processing that is as gentle on the product as possible. The presented functional principle of a continuously operating machine, especially in a two-lane design, does justice to this. Furthermore, with an arrangement of this type, very good accessibility to all process-relevant functional points is guaranteed with minimal space requirements. Aspects of environmental pollution, such as the reduction of noise emissions and vibration pollution, are also taken into account.
