Description

TITLE

Formateinstellvorrichtung

TECHNICAL AREA

The present invention relates to a format adjusting device according to the preamble of claim 1.

STATE OF THE ART

In packaging technology, products are often packaged in cardboard containers. For this purpose, cardboard flat blanks are withdrawn from a stack, fed to a forming and folding device and pressed by a die through a mold and thus they are formed into a cardboard container. The molded boxes are then fed to a packaging system, filled and closed again.

In order to be able to produce several different board formats on the same machine, individual parts of the machine have to be adapted or adjusted to these different sizes. For example, the following modules of the machine must be converted to the different carton formats: carton blank magazine, carton blank deduction, stamp, mold, positions of the glue nozzles in hot glue variant, various blank feeders and carton path transports.

Known solutions realize the adjustment in different ways.

For example, it is known to replace format-dependent parts, such as stamp and mold. These so-called change tools are adapted to the appropriate box format. Advantages of this solution is that the tools are preset and thus a short ramp-up (start-up time) of the production is achieved, that is the The machine runs within a short time with the new format again error-free and with maximum efficiency. There is no need to adjust at the start of production.

The disadvantage is that, especially in many formats, many tools are needed, which is expensive and requires a lot of storage space. Often the change tools are very heavy, so that during installation and removal partial lifting tools must be used.

It is also known that tools, e.g. Forming tools, the side walls and corner elements mounted on rails and adjustable with spindles. The spindles can be operated by hand or with servomotors. Such adjustments are made even with side guides or cardboard box.

The advantage is that no complex alterations have to be made in a format change. The ramp-up time for the variant with servomotor is very short, since the default setting can usually be stored. However, a disadvantage of the motor-driven variant is that it is very expensive, since separate servomotors with control must be used for each dimension. Also, the error rate is higher because more components are in use (electrical). The hand-adjustable variant is probably much cheaper, but difficult to adjust. In this case, the adjustment must be made with attached to the adjustment scale. In addition, fine-tuning must be done every time the production starts, so the ramp-up time will be longer, resulting in poorer availability. In multi-lane variants, this setting must be made on each lane, so there are countless spindles to adjust, which is costly and leads to a high error rate.

Another variant is the fastening of the individual elements of the mold by means of clamping screws on the rails. Although this is also a cost-effective variant, but has similar disadvantages of the spindle adjustment by hand. PRESENTATION OF THE INVENTION

Based on this prior art, an object of the invention is to provide a format setting device for devices for producing packages of different format or size and shape, which overcomes the disadvantages of the prior art. In particular, the format adjustment should have easier handling, as well as cost and allow a short start-up time of production after switching the device to a new format.

Accordingly, a format setting device serves for setting the format of at least one functional element on a packaging machine, in particular on a device for producing packaging of different sizes and / or shapes. The format setting device comprises at least one bearing element, at least one format gauge comprising at least one bearing section and at least one positioning element with at least one stop section, and at least one functional element with at least one connecting section. The format gauge can be connected to the bearing element via the bearing section. The abutment portion of the position element is connectable to the connecting portion of the functional element, so that the position of the at least one functional element with respect to the bearing element is adjustable. The arrangement of a format teaching a device can be created, which is easier to handle, which at the same time the time required for a format change can be reduced. Particularly advantageous is the fact that the functional elements can be connected to the position elements of the format gauge and thereby positioned.

The bearing element is preferably arranged stationary with respect to the format setting device and / or the packaging machine. Preferably, the abutment portion of the position element protrudes into the connecting portion of the functional element, wherein the format gauge is formed separately from the functional element.

Preferably, the format gauge has the shape of a along a central axis extending bar or the format gauge has the shape of a frame. Next are also format gauges in the form of plates or discs, in particular round discs, conceivable.

Preferably, the at least one format gauge in a format change as a whole with respect to the Formateinstellvorrichtung, preferably tool-less, interchangeable, each set format a preferably decided, preferably unique, format teaching or a dedicated, preferably unique, sentence is assigned consisting of several format teachings. Preferably, the functional elements remain in a format change in the packaging machine and are positioned according to the new format to be used. As a result, a particularly simple and above all faster format change can be achieved.

Preferably, different format gauges are available for different formats, whereby the format gauges are simply exchanged during a format change. With particular preference, each packaging to be produced is assigned a dedicated format theory. This has the advantage that when a format change the incorrect settings can be reduced because a format is assigned a corresponding format theory. Particularly preferably, a set of different format gauges is always exchanged. The format gauge is thus an interchangeable or an exchangeable element.

Preferably, the at least one position element is adjustable with the format gauge or adjustable or firmly connected. An adjustable or adjustable connection means that the position element can be adjusted manually with respect to the format gauge and that the position element can be fixed with respect to the format gauge at at least two different positions. With the fixed connection, the position element is in an unchangeable position with respect to the format gauge.

Preferably, the at least one position element is connected to the format theory via a frictional connection or a positive connection or a material connection.

With the form-fitting connection, the format gauge can be transferred to defined positions Have means with which the position elements can be brought into positive connection. Such means may be, for example recesses, teeth, dowel pins and / or locking means. The connection can be designed as a latching connection and / or plug connection. For example, a position element can be set to predefined positions.

Particularly advantageous, the position of the position elements on the format gauge can be adjusted continuously and be determined by a frictional connection. In particular, the position of the position elements can be fixed non-positively via a releasable clamp connection. This is usually done when setting up a format for the first time, and in production the position can be finely adjusted. These settings are retained even if the format is changed.

In the cohesive connection, the position of the position elements can be defined once on the format either during manufacture or during the first use and is then no longer changeable.

As an alternative to the types of connection, the at least one position element can be formed in one piece with the format gauge, ie, in one piece, for example, by casting and / or by production in a one-component or multi-component injection method and advantageously from a single blank. A one-piece format gauge can be produced particularly cost-effectively.

It is also conceivable to combine the above types of connection of position elements with the format theory, e.g. individual position elements can be made in one piece with the format gauge, others can be designed by means of locking means, others by means of frictional engagement. It is also conceivable that the position elements can be adjusted with spindles, servomotors, cylinders or other means.

Preferably, the functional elements are movably mounted on a guide rail, wherein the guide rail is preferably part of the packaging machine, and the format gauge is preferably arranged parallel to the guide rail, wherein the bearing element preferably in communication with the guide rail.

Alternatively, the functional element can be connected directly to the format gauge so that the functional element is essentially supported by the format gauge.

Further embodiments are given in the dependent claims.

A packaging machine comprises at least one format setting device as described above and at least one bearing element for receiving the format setting device. In such a packaging machine format change can be done very easily.

Preferably, the packaging machine further comprises at least one mold for forming a package from a blank, wherein the mold comprises at least one corner element and optionally at least one side member. Corner element and side element each comprise at least one functional section and a connecting section for receiving the position element of the format gauge. The packaging can be shaped via the functional section, for which purpose, for example, a forming punch can be used, which can be part of the forming tool.

Preferably, the packaging machine further comprises at least one adhesive nozzle, wherein the adhesive nozzle comprises a connecting portion which is in particular integrally formed on a holder in communication with the adhesive nozzle.

DESCRIPTION OF PREFERRED EMBODIMENTS

In FIG. 1, a format setting device 1 according to the invention is shown with reference to a forming tool, which will be explained in detail later with reference to FIGS. 5 and 6. The mold is used in the present case for the production of cardboard boxes for receiving packaged or unpackaged items. The mold will be explained in detail below. As a rule, devices are built and used which can produce packaging, in particular cardboard containers of different sizes and shapes. In this context, a format should be understood to mean a specific size and / or shape of a packaging. In order to produce a different packaging with the device, it may have to be converted to a new format. In this case, various functions of the device, such as blank magazine, stamp, mold can be converted to the new dimensions, such as length, width, height, possibly also the shape of the container.

By the term packaging machine can be understood a device for producing packages of different sizes and shapes. FIG. 2 shows a detailed view of an embodiment of the format setting device 1 according to the invention, which serves to adjust the format of a functional element on a packaging machine. This format setting device can be used, for example, in connection with the molding tool according to FIG. 1 or else in other devices.

The format setting device 1 comprises at least one bearing element 2, at least one format gauge 3 and at least one functional element 7, which can be aligned with the bearing element 2 via the format gauge 3. The format gauge 3 is connectable to the bearing element 2 and enters into a connection with the at least one functional element 7, so that the functional element 7 can be aligned with respect to the bearing element 2 or the format gauge 3. The position of the at least one functional element 7 is thus adjustable with respect to the bearing element 2. The format gauge 3 comprises at least one bearing section 4 and at least one positioning element 5 with at least one stop section 6. The functional element 7 has at least one connecting section 8, which can be connected to the stop section 6. In other words, it can therefore be said that the format gauge 3 can be connected to the bearing element 2 via a bearing section 4, and that the stop section 6 can be connected to the connecting section 8 of the functional element 7, so that the position of the at least one functional element 7 with respect to the bearing element 2 is adjustable.

During positioning, the functional elements 7 are prepositioned to the desired positions. Subsequently, the format teaching 3 with the bearing element 2 and the position elements 5 are connected to the functional elements 7, whereby the functional elements 7 are accurately positioned by the format teaching 3. In the case of a format change, the format gauge 3 can be replaced by another format gauge 3, whereby the format is automatically changed. A fine adjustment of the position elements 5 is omitted, so the changeover time can fall in a format change.

When using a format gauge 3 for the first time, the corresponding format must be set. When setting up a format for the first time, all necessary Format gauges 3 provided with the correct and the correct number of position elements 5, used in the machine in the right place and engaged with the functional elements 7. Now all position elements 5 are placed on the format gauges 3 in position and fixed so that the corresponding functional elements 7 are positioned for this format in the right place. When retracting the format, the functional elements 7 are finely adjusted by the corresponding functional elements 5 are set. This step is omitted in the embodiment described below with the fixedly arranged position elements 5. Now all interchangeable format gauges 3 can be marked with the appropriate format and any codes are attached. These format gauges 3 can be placed in stock as a format set and used again in the next production of this format. It is also ensured that the last fine adjustment made on the format gauges 3 is still set.

The at least one bearing element 2 is stationary relative to the format setting device 1 or the packaging machine in which the format setting device 1 is arranged. That is, the position of the bearing element 2 serves as a reference point for the adjustment of the functional element 7. It can therefore be said in other words that the functional elements 7 are aligned with respect to the bearing element 2 or positioned.

The format gauge 3 comprises, as already mentioned above, at least one bearing section 4 and at least one position element 5 with at least one stop section 6. The bearing section 4 serves for the connection to the bearing element 2. The positioning element 5 with the stop section 6 serves to position the functional element 7. Preferably, the number of position elements 5 corresponds to the number of functional elements 7. Here, two mounting sections 4 are arranged.

The functional element 7 has at least one connecting section 8. The connecting section 8 is formed corresponding to the stopper section 6, and the functional element 7 can be positioned via the stopper section 6 and connecting section 8. Next, the functional element 7 at least one Functional section 22, which serves the execution of a specific function.

The bearing element 2, which can be clearly seen in FIGS. 3 and 4, comprises in the present embodiment a first receiving space 11 for receiving the size gauge 3 and a second receiving space 12 for receiving parts of the size gauge 3. In the present embodiment, the two Receiving spaces 11, 12 provided by spaced bearing blocks 13. The first receiving space 11 is defined by the space between the two bearing blocks 13 and the second receiving space is provided by recesses in the bearing block 13.

The format gauge 3 is formed in the present embodiment substantially rod-shaped and extends along a central axis M. The cross-section of the rod may be varied, in the present embodiment, a round cross section is shown. Alternatively, an angular or polygonal cross-section would be conceivable. Transverse to the central axis M extends in the region of the storage section 4, a bearing pin 14. This bearing pin 14 projects in the connected state with the bearing element in the second receiving space 12, while the rod 9 protrudes into the first receiving space. About bearing pin 14 and rod 9 of the storage section 4, the format teaching 3 is aligned with respect to the bearing element 2 in all 3 directions.

In the present embodiment, two bearing elements 2 are arranged and the format gauge 3 also comprises two bearing portions 4, which are arranged at the end of the corresponding rod 9.

The position elements 5 can be permanently or adjustably connected to the format gauge 3. Under fixed is understood that a user can make any adjustments to the position elements 5, because the position elements 5 with respect to the format teaching 3 firmly connected. Consequently, a format format for a fixed format is provided. This embodiment is particularly advantageous if a subsequent fine adjustment should not be necessary. In the adjustable or positionable variant, the user can adjust the position of the position elements 5 with respect to the format gauge 3. The position of the position elements 5 can then be set on the format gauge 3, with a fine adjustment at a later date is still possible. In this embodiment, tolerances and errors can be compensated by the fine adjustment during production. The compensation is then to be used again in a further use of the same format gauge, whereby the fine adjustment are automatically taken over even in later production.

In other words, it can be said that the at least one position element 5 can therefore be connected to the format gauge 3 by way of a frictional connection or a form fit or a material connection.

In the present embodiment, the position element 5 is clamped to the format gauge 3 via a screw connection 15. Consequently, it is an adjustable embodiment. The position element 5 in this case has an opening 16 which corresponds to the cross section of the rod 9 and a slot 17 which extends from the opening 16. The screw 15 extends through the slot 17, wherein the slot 17 and the opening 16 are reduced when tightening the screw 15, so that the position element 5 is clamped to the format teaching 3 and the rod 9. The position element 5 is preferably additionally secured by a pin connection or by the application of a varnish to the format gauge 3.

In the cohesive connection, the position element 5 is fixed, for example via a welding ssverbindung, with the format gauge 3 in connection.

Alternatively, it would also be conceivable that the format teaching 3 has corresponding sections which allow a positive connection with the position element 5.

In a further alternative embodiment, the format gauge 3 can also be formed integrally with the position element 5. This would be particularly advantageous, for example, if format gauge 3 and position element 5 consist of a stamped part. Alternatively, it could also be a corresponding rotary part in the format teaching act radially extending punctures.

The positioning of the position elements on the format gauge 3 has the advantage that different format gauges 3 can be provided for predefined formats. When changing the format on the packaging machine, if necessary, the user then only has to choose another format gauge 3 and can adjust the functional elements accordingly using this format gauge 3. Consequently, there is no need for elaborate fine-tuning of the functional elements 7. In this connection, it may be mentioned that a particular format gauge can be used for several formats if the settings of the corresponding format gauge are the same for the different formats.

The abutment portion 6 of the position element 5 projects here in the connecting portion 8 of the functional element 7 a. For this purpose, the connecting section 8 has two cams 18 which provide a recess 19 for receiving the stop section 6. It would also be conceivable that the abutment portion 6 of the position element 5 as a recess and the connecting portion 8 form as in the recess matching element.

In a further development, a format gauge has 3 differently shaped position elements 5. Accordingly, the connecting portions 8 are formed differently from each other, so that the position elements 5 can be brought into engagement only with a certain connecting portion 8, so that a format gauge 3 can be used for setting of different formats. Preferably, the position elements 5 and the connecting portions 8 are each formed such that only a specific format can be set, wherein a corresponding position element 5 can protrude into a the connecting element 8 assigned to the position element 5, which in turn a coding can be achieved. Preferably, the engagement of the stopper portion 6 is coded in the connecting portion 8, so as to ensure that the connecting portions 8 of the functional elements 7 with the correct stop portions 6 engage or that there is no confusion or mixing in the different formats or that to no confusion between position elements and connection sections of a certain format theory 3 of a certain format comes. The coding can also be carried out by means of a visually perceptible marking, such as the stamping in of numbers, letters or the application of a color.

Further, the storage section 4 may be formed encoded. This can ensure that the format gauge 3 can be used only in a predefined position in the bearing elements 2 and / or in the correct bearing element 2. Thus it can be prevented that the format teaching 3 is used wrongly or in the wrong place. In other words, it can be said that when, for example, the gauge is designed as a rod, with the proper coding, it can be prevented from being used in the wrong way. Or, if there are several equally-formed format gauges per machine, this can prevent a format gauge from being used in the wrong place, thus making the format setting incorrect. The coding can be provided for example by a different design of the storage section 4. For example, by the choice of different diameters for the bearing pin 14 and the second receiving space 12 and / or by the choice of a different dimension of the bearing portion 4 of the format gauge 3 itself and the first receiving space 11. Also, the coding by a visually perceptible marking, such as the impressing of numbers, letters or the application of a color.

The at least one functional element 7 is preferably connected to a guide rail 10 in connection and is movable relative to this guide rail 10. The guide rail 10 may be part of the packaging machine or be part of a functional element. The bearing element 2 is preferably fixed to the guide rail 10 in connection.

In an alternative embodiment, the functional element 7 can also be suspended directly on the format gauge 3, so that the functional element 7 is essentially supported by the format gauge 3.

The format gauge 3 can be designed differently depending on the application. For example, as a rail, rod, plate or disc. For a disc is preferred a circular disc is selected, which has at its periphery different vertically adjustable rods, which can serve as stops. In this variant, the format gauge is not replaced, but rotated so that the rod corresponding to a particular format comes to the place where it can be brought into engagement with its associated element.

FIGS. 5 and 6 show schematically the application of the format setting device according to the invention in connection with a forming tool for producing a container from a flat blank. The parts have in principle the same reference numerals according to the above description.

The functional element 7 here has the shape of form elements, here of corner elements 20 and side elements 21, on. The mold members 20, 21 include a connecting portion 8 and a functional portion 22. The connecting portion 8 is brought into contact with the stopper portion 6 of the positioning member 5, and the functional portion 22 serves to form the container.

The two corner elements 20 are slidably mounted on one side of the container to be formed on a first common guide rail 10, the two other corner elements of the second side of the container to be molded mounted on a second guide rail 10. With a format guide 3 assigned to the first guide rail 10 and first corner elements, these first two corner elements are positioned at the corresponding position by engaging the connecting section 8, here the groove of each corner element 20, with the corresponding stop section 6, here the cam, of the format gauge 3 becomes. Similarly, the two other corner elements 20 are brought into engagement with a second format gauge 3. Thus, the shape with respect to the first direction L has been set to the correct size.

In order to set the width of the mold to the correct size, the two guide rails 10, which carry and guide the corner elements 20, also mounted slidably. However, they are displaceable transversely to the sliding direction L of the corner elements along the direction B. In order to fix the guide rails 10 in the correct position, the guide rails 10 are provided with a 'connecting section 8'. Here, a groove, equipped, which with a stop portion 6 ', here a cam of another format teaching 3' is engaged. The guide rails 10 are brought on both sides, each with a format gauge 3 'into engagement, wherein each one side of both guide rails 10 with the same further format gauge 3' is engaged. In this case, the guide rail 10, which in turn contains the corner elements 20 with associated format gauges, the functional element 7 and the further format gauge 3 ', which can be mounted in the machine housing, is the associated format teaching 3. Thus, four format teaching 3, 3' for the adjustment of the form necessary.

Alternatively, these four format gauges may also be implemented as a rectangular frame containing all stop portions 6 of the individual format gauges 3, 3 '.

In the example shown in Figure 1 four boxes are formed side by side. This means that not only the two corner elements 20 of the one mold are mounted on the guide rails 10, but a total of eight corner elements, two per form. The corner elements 20 can be removed and replaced depending on how many containers are to be formed in parallel. In FIG. 5, this is shown with two corner elements 20 arranged next to one another.

It should also be noted that not only containers with rectangular floor plans can be processed. There are also other shapes, such as octagonal, rounded and other shapes conceivable. For this purpose, functional forms adapted to the shapes must at most be used.

For larger containers, it is possible in addition to the corner elements 20 also use side elements 20 so that a better stability of the container can be achieved during molding. This is shown in FIG. In this case, a possible coding may be such that in each case the left corner elements 20 are provided with larger cams and the right corner elements 20 are provided with smaller cams. In order to prevent that the format gauges 3 can not be inserted or confused incorrectly, a suitable coding can also be used with these. The format gauges 3 can at their individual ends with bearing pin 14 of different lengths or diameters be equipped, or there may be different versions of cam and groove, such as frontal groove or ring-like cam, respectively. Federal are used. Alternatively or additionally, the format gauges 3 may have different lengths or diameters. Other types of coding are mentioned above and are equally applicable here.

FIG. 7 shows a further embodiment of the format setting device 1. Here, the format setting device 1 is shown in connection with a carton magazine. A carton magazine 25 must be adapted to the size of the carton blank. From this cardboard magazine, a cardboard blank is removed, which can be fed, for example, to the molding tool shown above.

Most such magazines also have a pre-transport 26, which is arranged below the blank stack. The pre-transport consists of two circulating belts, which are each attached to a support 26a. The two supports 26a must be positioned laterally according to the size of the blanks. In this case, the two beams 26 a are each an element which are provided with connecting portions 8. The format gauge 3 is in this case a cover 27, which is arranged on the machine-side end of the magazine 25 and at the same time serves as a security cover. The corresponding position elements 5 are now bolted to the correct location on the disc. This disc is replaced as format gauge 3 if necessary.

FIGS. 8 and 9 show diagrammatically the application of the format setting device according to the invention in connection with an adhesive application tool for bonding sides of a container from a flat blank. The parts have in principle the same reference numerals according to the above description. Such a device can be used, for example, to glue elements formed by the molding tool. For this purpose, the adhesive nozzles 30 for spraying the hot glue are also to be positioned correctly. The glue nozzles 30 are individually mounted on a respective holder 31. This holder 31 is slidably mounted and has a connecting portion 8 which is engaged with a corresponding abutment portion 6 of the vertically mounted format gauge 3. The format gauge 3 is used and the individual holder 31 vertically shifted so that they with their corresponding stopper section 6 come into engagement. The connecting element 8 is pushed from above onto the stop element 6 and suspended, so that the holder 31 is fixed.

Since the glue nozzle holders 31 are vertically slidably mounted, when replacing the format gauges 3, the holders 31 would fall downward by gravity. This can be prevented by the following special design. Each element / holder has two connecting sections 8. When changing the format, the new format bar is used in a second bearing element 2 '. Subsequently, the holders of all glue nozzles are converted from the groove elements of the first, old format rod to the groove elements of the second, new format rod. Finally, the old format bar is removed.

As an alternative, which is shown in FIG. 10, the holders 31 of the glue nozzles 30, which are mounted so as to be vertically displaceable, can strike a stop 6 of the format gauge 3. On a circular disk 32 vertically adjustable bars 33 are mounted on the perimeter per format. These rods 33 serve as a stop for the glue nozzle holder 31 and are set to the correct height per format. When changing format, the format gauge 3 is not replaced but rotated in the correct position.

FIG. 11 shows a further alternative embodiment of the format setting device 1. The same parts are provided with the same reference numerals. In principle, the format setting device 1 according to FIG. 11 is essentially identical to that according to FIG. 2 or FIG. 2. The right-hand storage section 4 has a groove 36 mounted on the front side of the rod 9. The right-hand storage section 4 is connected to a storage section 2, wherein the groove 36 comes into engagement with a bearing journal 2 mounted on the bearing section 2. The left storage section 4 is formed differently from the storage section of the format gauge according to FIG. Here, the left storage section 4 comprises two circumferentially extending around the rod 9 elevations 34, which form a groove 35. With these two elevations 34, the rod 9 comes into contact with the storage section 4. This can be subsequently in a simple manner Positioning elements on the format gauge 3 can be added or removed by sliding them up or down.

In summary, the format setting device has the following advantages:

Simple and cost-effective adjustment

Fine-adjusted format gauges can be created per format, so the ramp-up time is minimal when changing to a new format

Readjustment during normal production of a format is possible at any time

There are no large and expensive format parts necessary. The format gauges can be made very inexpensive and small.

There is a great deal of flexibility, you are not limited to a fixed number of format elements. The number of elements per format can vary.
