Description

The present invention relates to a method of manufacturing a box provided with a coating on an outer surface. Another aspect of the invention is a production plant, with which the production of beverage crates is simplified. The invention further relates to a beverage crate whose coating extends contiguously across edges of the beverage crate.

State of the art

Boxes z. B. for beverage containers or bottles serve the beverage trade for safe storage of beverage containers, especially in sales rooms and for transport. It is a mass product in the form of a reusable packaging, which must meet in particular requirements for labeling the content in order to find acceptance in the trade.

Meanwhile, a large variety of forms of reusable boxes has been developed, which is also reflected in part in a variety of forms of accommodated in the boxes containers or containers. In this context, by way of example to the patent DE 10 2007 048 310 B4 (Owner: Oberland Engineering GmbH, filing date: October 9, 2007). This document describes the formation of quills in a bottle crate, which is suitable both for holding individual bottles and for group packaging, ie single bottles grouped in groups of bottles. A change in design features often requires a complete redesign of the injection molding tools required for manufacturing, which also requires increased materials and control algorithms.

Various general process steps for producing an injection-molded container go z. B. from the DE 10 2010 024 383 A1 (Applicant: Ilsemann Automation, filing date: 15 June 2010). Therein, a container in the form of a plastic shell of three layers and a method for producing the same is described. The shell has conical walls and has an inner layer formed by a barrier film, an outer layer formed by a label, and an intermediate layer which is introduced in an injection molding process. Overlapping areas of the barrier film must be folded and specially sealed to create a suitable transition area. The transition region is needed so that the barrier film can be embedded in an injection molding assembly. The outer layer in the form of a label is also referred to as in-mold label, which enters into a solid connection with the hot injection molding compound. During the casting process, the outer layer of the injection molding compound is pressed firmly against an outer wall of an injection mold.

A tool with which a plastic box is produced, is in the document DE 10 2004 009 406 B4 (Owner: Theysohn Formenbau GmbH, filing date: 24 February 2004). The injection molding tool comprises four mold jaws for determining the outer shape of the plastic box. Each mold jaw encloses a corner of the box or an edge of the box. Furthermore, a recess for receiving a film is provided in each mold jaw, which is guided around the corner or edge of the box. This film is back-injected with plastic during the production of the box.

The above-mentioned documents apply in the context of the present invention description as further evidence of common usage of injection molding technicians, plastics technicians and mold makers, as far as individual terms, wording and wording for the reader in the following presentation should be incomprehensible.

task

The strict competitive situation z. B. causes in the beverage industry that often new product lines are introduced and the appropriate dosage forms must be adapted to the image campaigns of the advertising departments of beverage manufacturers. High requirements for beverage crate manufacturers result from the fact that the lowest possible production costs for the fastest possible production change and a high quantitative output of boxes is desired, for. B. to be able to supply retail outlets at short notice. Therefore, there is a need for convenient shapes of boxes that also provide a pleasing appearance. The boxes should be produced quickly and in large numbers with the simplest possible process steps. A production plant should also deliver high-quality boxes of varying appearance with the least possible changeover times. The product error rate should be kept as low as possible.

invention description

The object of the invention is achieved by a method according to claim 1, by which a box with a coating can be produced, a suitable production plant of a beverage box can be found in claim 11. a beverage box according to the invention describes claim 14. Advantageous developments can be found in the dependent claims.

In the manufacture of a box, its appearance can be modified by changing a coating with little effort. The method is particularly applicable to beverage crates. Here, the basic dimensions of the box can remain the same. Cheap dimensions are z. B. a box bottom area of 400 mm to about 300 mm. Such boxes provide a bottle interior with a width of z. B. 286 mm. Such a box can z. B. about 270 mm high. If the box equipped with sloping walls, so arise z. B. on the one hand a width of 300 mm, while on the farther side is given a width of only 286 mm. A crate, the z. B. has the dimensions set out above, for example, can accommodate reusable bottles in an upright position next to each other. A crate can also sets of bottles, such as so-called "six-packs", the z. B are combined in a box to a subset in the box, protect against shocks from the outside. A drink bottle transport container, which is composed of at least two boxes, is particularly popular among walkers. Such a beverage bottle transport container is divisible, so that for transport a first part container with a subset of bottles z. B. in the right hand and the second part of the container can be taken with a second subset bottles in the left hand.

The box can be coated on several sides with a flat element. Also, a partial container or a sub-box can be regarded as a box. Sub-boxes and sub-containers are preferably combined in pairs with each other to form a box unit. A box or sub-container of a beverage bottle transport container may be coated with a continuous label. The coating extends flat on a surface area of the box. A color-coordinated layer or a surface-structured layer can form a decorative layer as a coating of the box. It can z. For example, photographic elements depicting portraits of people or landscape can be placed on the box. By using a label film as a coating can on ingredients, eg. B. of beverages in the box, or be pointed out to special taste notes. A label may contain text or picture elements to advertise a product or to signal a source of origin, e.g. By the name of a manufacturer, with the method of coating on a box. Furthermore, it is possible to provide in a coating of a box window elements which are arranged in a side wall of the box. Window elements reduce the weight of the box. The label film can also extend to the edge regions of window elements of a box. It can be used as a protective membrane z. B. be formed against the deposition of dust particles on bottles.

In a priority step of the process for producing a coating of a box is a flat, extended element, the z. B. from a plastic, a cellulosic material such as paper, a metal foil or a multilayer membrane, introduced into an injection mold. By being applied to an outer mold of an injection molding tool, the extended element is transferable to an outer surface of a box. The application takes place in particular on an inwardly facing surface of the outer mold jaw. Textually, figuratively or color-designed patterns, which may have the extended element, are applied to the outer mold jaw. The information-carrying side of the extended element faces outwardly on an inwardly facing surface of the injection molding tool. At least one surface of the outer mold jaw is occupied by the extended element. In a subsequent step, a flowable molding compound is introduced into the mold formed by the injection molding tool. The result is a compound of the extended element with the molding compound. In the injection molding tool, the molding compound is distributed to fill a gap corresponding to the final shape of a box. Behind the flat, extended element, the molding compound is injected, wherein air escapes from the gap of the injection mold. By injection molding, the formation of the box in the area of the label, more precisely on its back, can be accomplished. The back-injected label also serves as a shape-limiting component. According to another aspect, the back-injected label takes over the shaping of the flowable molding compound. The extended element forms a coating on the box. The flowable molding compound can solidify on the extended element, in particular in a laminate, to form a coated, box-shaped unit.

The outer mold jaw of the injection molding tool has mutually angled side regions; several sides of the outer mold jaw advantageously form structural forms. The negatives of the structural forms can be found in the box produced. Parts of individual pages are used to form the box and parts of individual pages are used to hold the flat, extended element. Areas of a page are therefore intended for special tasks. These side areas are parts of the injection mold. At least three side regions of the outer shaping jaw, which adjoin one another, each form an angular position in the manner of a polygon angle relative to one another. The page areas are in particular integrally formed contiguous. Each side region may have concave and / or convex shape elements on a planar extent of the side region. A side region may further include pits and / or bulges. Three side areas are preferably arranged in a U-shape relative to one another.

In the priority process step for applying the extended element to the injection molding tool, an approach of the flat, extended element is performed on the outer mold jaw. The extended element is arranged on an element carrier and movable by means of element carrier. A movement of the element carrier spends the extended element to a bearing surface of the outer mold jaw. The movement of the element carrier to overcome the spacing between the outer mold jaw and the extended element takes place in one plane. In one embodiment, the approach movement corresponds to the movement of an injection molding core, which can be positioned in an interior of the injection molding tool. The movement course is advantageously aligned alongside an extension of a box bottom. The movement takes place along a shaping jaw, which defines the bottom of the box. The bottom of the box is created in particular by introducing the flowable molding compound into the injection molding tool.

Large quantities of similar boxes can be produced in an injection molding process. A suitable production plant for producing a beverage crate comprises an injection molding tool. In a production plant, two or more beverage crates or sub-crates of a plug-together beverage crate can be produced side by side in one process step at the same time. In one embodiment, several boxes or sub-boxes can be produced in one operation in an injection molding tool. Repeated execution of a production process makes it possible to rapidly produce quantities of more than a thousand crates. Process steps can be carried out synchronously on at least two juxtaposed injection molding tools. In an alternative process, alternate sub-boxes are produced in a production plant. While one part box is ejected, the shot takes place in the other injection mold.

The production plant comprises a robot arm with which transverse movements, longitudinal movements with respect to a position of the injection molding tool can be carried out. At least one element carrier is mounted on the robot arm. The robot arm can change an angular position of the element carrier in a controlled manner. The element carrier is moved in a controlled manner. An electronic control determines the movement sequence of the robot arm. With the robot arm positions of the element carrier and / or angular positions of the element carrier can be approached accurately. It is advantageous if positions of the robot arm can be sensed. The controlled element carrier passes over a track between an injection mold, in particular an outer mold jaw, and a magazine. The distance of the element carrier to the magazine and the outer mold jaw is adjustable. The electronic control directs the robotic arm to a magazine in a position-accurate manner, whereby both a rotation angle and a tilt angle of the element carrier can be controlled. In an end position of the element carrier, flat, extended elements can be picked up or set down. A predetermined number of extended elements, in particular a single extended element can be removed with the robot arm from the magazine. The transfer of the extended element from the magazine to the element carrier takes place with exact position. The extended element is to be brought to its final position in the injection mold. The extended element should be placed as exactly as possible in the end position, ie in its positioning. This is done by a gradual approach to this end position or final positioning. The positioning of the flat, extended element may, for. B. be monitored by a detectable only under infrared light (IR) or only under ultraviolet light (UV) mark the extended element. For this purpose, at least one dye marking can be provided on the extended element. The element carrier in particular comprises a sensor element, such as a camera, for detecting the position of the extended element. The camera can also be used for quality control of images on the flat, extended element.

The robotic arm conveys the extended element from the magazine to the injection molding tool. A single extended element from the magazine can be deposited with exact position on an outer mold jaw of the injection molding tool. The position determination between the element carrier and the outer forming jaw can be carried out particularly accurately with an optical measuring device, so that an electronic control loop can compensate deviations of more than 1 mm by movement of the robot arm.

The element carrier is connectable to the extended element via a suspension force. The attachment force can in particular be formed between the extended element and the element carrier via an air pressure supply. The attachment force fixes the extended element preferably via an applyable negative pressure on the element carrier. By compressed air supply from at least one Opening the element carrier to the extended element, the extended element is detachable. The air pressure can fix the extended element, which is subjected to negative pressure on one side, to the element carrier. By means of a switched by the electronic control valve, the air pressure is variable compared to the atmospheric pressure of the ambient air, for. In a production hall. Underpressure is an air pressure which is less than the atmospheric pressure of 1 bar and which in particular is sufficient to form the appending force of the extended element to the element carrier. The attachment force can be switched off by applying an air pressure that exceeds the negative pressure, in particular by applying an overpressure of air compared to the atmospheric pressure of 1 bar. The Anhängkraft can be generated as an alternative to the air pressure method with a static charging process. The attachment force can also be generated electrostatically. By virtue of different static electrical charges, attractive coulombic forces can be formed between the extended element and the element support or the outer mold jaws. By the same static electrical charges, repulsive coulombic forces can be formed to the extended element which overcome the appendage forces. The electrical charges can be supplied to the extended element, the outer mold jaws or the element carrier by electrical lines of suitable electrical potentials. Preferably, the flat extended element has at least one insulating, dielectric layer.

An inventive beverage crate can z. B. be prepared with the inventive method and / or a production plant according to the invention. A crate provides space for at least one beverage container, such as a bottle or a bottle set. Preferably, a beverage box comprises at least two parts, whereby the weight of the bottles z. B. can be better distributed for manual transport. An inventive beverage crate preferably satisfies ergonomic requirements, eg. B. by rounded handle structures. Two-piece beverage crates can be firmly connected to each other by plug connection or by clip connection or by ironing connections. From the two sub-boxes through the connection is a beverage crate. A separation into two separate crates is possible with a simple handle. In a composite beverage crate at least two sides facing each other and therefore not visible to the outside or from the outside. At least three sides of a sub-box form an at least partially continuous surface having a foil coating. At least three sides of the beverage crate are coated with the flat, extended element. The flat, extended element forms a connection edge-free unit. Surface areas of the extended element hang over at least three sides of the beverage crate together. Butt edges or overlapping edges are not formed between areas of the extended element. The box side surfaces include an interior angle to each other. Preferably, at least two box side surfaces include an angle that is more than 90 °. The angled position of the box side surfaces may be diamond-shaped. The angle can be taken or measured with respect to a bottom surface of the beverage box on a side wall. It is also possible to specify internal angles of more than 95 ° between two box side surfaces in order to form a trapezoidal structure. In the trapezoidal structure z. B. be assigned along a box bottom surface longer surface edge a second sub-box and be spaced along a box bottom surface shorter side edge of the second sub-box.

The presented method is able to produce a high number of beverage crates with only short cycle times or cycles. The firing order is increased. For this purpose, the production plant is arranged so that the flat, extended element can be accurately positioned in the outer mold jaws introduced. The result is a beverage box or sub-box that has at least three sides of a contiguous label, label, decorative layer or protective layer. The beverage box or sub-box may be referred to as a bum-free beverage box.

In the following, advantageous embodiments and developments are set forth, which in themselves, both individually and in combination, can also disclose inventive aspects.

The shape of the element carrier can be stretched. With a change in shape, at least one region of the element carrier can be adapted to a shape of the outer forming jaw. The change of a shape of the element support also affects the shape of an extended element held by the element support. The variable shape region of the element carrier carries at least a partial surface of the extended element. A change in position of a region of the element carrier can bring about an approximation of the element carrier to the outer mold jaw. At least a partial surface, such as a curvature of the extended element, may be affected by a change in shape of the element carrier. A surface region of the extended element can preferably be applied to the outer mold jaw with the element carrier by a change of shape. In the priority process step, it can also be said, in the prearranged process step, a movement is performed, which leads to a Change in position of the element carrier can lead. The movement may also cause a change in position of a partial surface of the extended element. In particular, the movement carried out from a first position, carried out by at least a portion of the element carrier, in a second position of the region of the element carrier. Preferably, the movement is carried out transversely to the movement in the priority process step. The movement leads the element carrier into a final positioning. In a final positioning, a reversal of a direction of movement or a change of a direction of movement can take place. A movement transverse to the movement in the priority process step z. B. along a surface which extends in an inner space with respect to an outer mold jaw. The movement can be executed with a change of direction. It is possible to carry out the movements at least in sections along a path, such as a straight path or a curved path. With the movement, a final positioning of at least a partial surface of the extended element vornehmbar. To maintain high timing speeds, precise positioning is helpful.

The extended element can be brought to the outer mold jaw from a predetermined direction. In the feeding of the extended element to the outer mold jaw, an angle of the extended element with respect to an angle of the outer mold jaw is brought into a position. The angles can be described by two legs each. Here, the respective angular ranges can be arranged parallel to the legs. A movement then preferably takes place predominantly parallel to a first limb which extends along a first side region of the outer shaping jaw. A movement can also lead to a leg, so that a leg which is associated with the extended element, moves toward a leg of the outer mold jaw. The outer mold jaw may have a plurality of side portions. A first side region is preferably arranged at an angle to a second side region of the outer shaping jaw. The angle can be greater than 90 °. Preferably, the angle is greater than 95 ° in order to improve a freedom of movement between the outer mold jaw, in particular a side region of the outer mold jaw and the extended element, in particular a partial surface of the extended element. The angle between a first side region of the outer shaping jaw and a second side region of the outer shaping jaw is in particular less than 180 °. The angle can also be less than 120 °. The Elemententrä ger preferably has two angles. A shape of the element carrier may be precisely matched to a shape of the outer mold jaw. In particular, an element support configured in the form of a counter-shape to the outer mold jaw extends in regions along an outer mold jaw, preferably along a side region of the outer mold jaw. In a final position of the element carrier, the element carrier can occupy a parallel position to at least one, preferably at least two, even better to three side regions of the outer mold jaw. In a final positioning of the element carrier, the latter preferably has at least one precisely fitting angle with which a flat element arranged equiangularly is transferable. The extended element is transferred to the outer mold jaw. At least three side portions of the outer mold jaw are covered with the extended element. A first, a second and a third side region of the outer shaping jaw can be covered at least on part surfaces with the extended element. Thus, it is possible to avoid wrinkles and Winkelunstimmigkeiten the flat, extended element with respect to the outer mold jaw. A possible bilateral backflow of the extended element is prevented by the exact positioning, a so-called encapsulation. This measure also contributes to reducing the clocking durations and to increasing the firing sequences.

In one aspect, the extended element may be changed in its spatial arrangement and in at least one extension direction. A movement of the extended element is preferably carried out when it sits on the element support. In the controlled movement of the extended element, a contact or adhering of partial surfaces of the extended element to a second partial surface, which is not assigned to an end position of the element carrier, is avoided. Scratching or grinding marks on the flat, extended element, which can lead to a deterioration of the adhesive properties or the visual appearance, can be avoided with a targeted movement. The extended element is spread over a larger area. The change of the planar arrangement of the extended element is preferably carried out with a drive which acts on the element carrier. The driving force can in particular be mediated mechanically by a freestanding shaft. A rotation angle of the shaft may be associated with an extension of the shaft. An extension of the shaft is transferable to at least a portion of the element carrier, as at least one mounting bar. An electric motor or a hydraulic-pneumatic drive can act on the element carrier via the shaft and convey a movement. With an electric motor drive can achieve a higher positioning accuracy. A hydraulic-pneumatic drive can be operated very quickly and conveniently with a system for moving Combine components of the injection mold, z. B. of external shaping jaws, cores, etc. The actuation, in particular of the element carrier can be mediated via transmission elements, such as mounting strips, mechanically or be effected with a mechanical drive. At least one mounting strip can cause a spreading of an element carrier. A preferably free-standing support strip may be formed at least partially as a shaft. The change of the element carrier serves to position the extended element. By the drive and the effect mediation of the support bar, the flat, extended element can be smoothed or stretched and then fitted in its final position. A direction of movement of the support bar, the element carrier and the extended element is preferably along a direction which feeds on the outer mold jaw. The movements are simplified, the movement can be handled faster. The clock rate is so steigerbar.

After applying the extended element to an outer mold jaw further components can be connected to the outer mold jaw. The outer mold jaw with the extended element is z. B. completed by inserting the injection molding core to the injection molding tool. For example, an angle of the injection molding tool can be specified. An angle can be formed by attaching at least one second outer mold jaw to a first outer mold jaw. A side portion of a first outer mold jaw may be extended by combination with a second outer mold jaw. The position of the extended element on the outer mold jaw, in particular the first outer mold jaw, remains unchanged. The connection of the outer mold jaw with a second outer mold jaw is closable at an edge region. The impetus of the outer mold jaws forms a linear connection. The combination of the outer mold jaws is tight with respect to the molding compound for injection molding. The impulse is closed as far as possible without an extensive, flat overlap between the outer mold jaws or outer mold baking parts. Thus, the material requirement for the outer mold jaws can be reduced. To complete the injection mold, side portions of outer mold jaws are connected together. Depending on the embodiment of a box to be produced, several connecting steps can be provided. An edge region of a box to be produced can be formed by a first side region and a second side region of an outer shaping jaw. An edge region of a box to be produced can also be imaged by the shape of an outer forming jaw. A side region of a box to be produced extends at least partially along an outer mold jaw. Furthermore, an edge or a side of a box to be produced may be stencil-like fixed by an outer shaping jaw or an arrangement of at least two outer shaping jaws. The shape of the box corresponds to an image that is limited by the shape of the outer mold jaw. The outer mold jaw may have an at least two-part subdivision. A first part of the outer forming jaw is associated with a first height area of the box. A second part of the outer mold jaw is assigned to a second height range of the box. The first height range and the second height range may be arranged one above the other with respect to a bottom of the box to be produced. However, it is also possible, in an advantageous box shape, to associate the first height range with a first side range and the second height range with a second side range. Here, the bottom portion of the box from the upper portion of the box through which z. B. bottles are inserted into the box, spaced. The spacing is in particular greater than an extension between the bottle bottom and bottle cap. With collapsible and divisible, at least two-part outer mold jaws can the removal of the box from the injection mold faster and less stress z. B. to avoid deformation of a solidifying box. A first part of the two-part outer mold jaw is displaceable with respect to the injection mold. The displacement of a part of the outer mold jaw can be carried out before inserting a flat, extended element. To form the injection mold, a first part of an outer mold jaw can be moved toward a second part of the outer mold jaw. Two parts of a two-part outer mold jaw can be synchronously moved to an end position to connect to an outer mold jaw together. The second part of the two-part outer mold jaw z. B. be used for molding a box part. Particularly advantageously, a second part of a two-part outer mold jaw can be used to form a bump wall of a box part. The shape of the bumper wall is precisely matched to a second bumper wall, which may be associated with a second box part. At the bumpers box parts can be combined. Formations of the impact wall form detents or connectors for box parts and are generally not visible in the assembled state. The curing only has to run so that the visible from the outside walls, edges and spots look well sprayed. As a result, the timing in the production is further increased.

The flat, extended element is preferably applied to areas of the outer mold jaw, which are at least in end portions of a baffle wall spaced. During the movement of the element carrier are the corners and Edges of the extended element in reaching the final position in an inner region of the outer mold jaw. There is a transfer of the extended element of the element support on the outer mold jaw. A retaining connection between the extended element and the outer mold jaw is made. The position of the extended element and the outer mold jaw can be fixed by means, wherein z. B. a negative pressure is exerted at least in a surface region of the extended element of an adjacent side of the outer mold jaw. By pulling a vacuum, the extended element can be held in one position. In a vacuum process applied to the extended element, gas, e.g. As compressed air, fed to one side of the extended element and / or be discharged from a second side of the extended element. The gas supply side is preferably the side with which the extended element bears against the element carrier. The gas discharge side is preferably the side where at least a part of the flat extended member contacts the outer mold jaw. The vacuum process may spend the extended element in the final shape. The position of the extended element on the outer mold jaw can be maintained as an alternative or in addition to the vacuum process with a static charge method. For this purpose, the outer mold jaw is preferably stored free of ground and can be acted upon in particular controlled by an electrical potential. Coulomb forces pull the flat extended element through an electric field to the outer forming jaw. A precise or positionally accurate placement is possible, which avoids disturbances in the manufacturing process and concomitant reductions in the clock rate.

In the injection molding, a material connection between the extended element and the surface formed by injected hardening molding compound is closed. By maintaining the position of the extended element, warping of the flat, elongated element due to heating or the formation of bubbles or wrinkles is prevented.

In a continuous manufacturing process, an injection molded box having a flat, elongated member at the surface must be peeled off the outer mold jaw to prepare the outer mold jaw for a second box manufacture. A detachment of the extended element from the outer mold jaw can be promoted by a printing process in which gas is introduced through regions of the outer mold jaw to the extended element. Between the surface of the outer mold jaw and the surface of the extended element, a gas pressure builds up, which lifts the respectively abutting surfaces, in particular of the extended element, from the outer mold jaw. With the printing method, the removal of the box from the injection mold can be performed faster, especially because the air flow and the cooling and solidification of the box for removal from the injection mold can be performed faster. This measure also contributes to increasing the timing or shortening of the timing times.

The design options for a box shape can be further improved by having an outer forming jaw at least one movable punch, such as a handle stamp or a window jaw slider. At least at one of the side regions of the outer mold jaw, a stamp may be arranged, the position of which is variable. The punch is movable with respect to the side portion of the outer forming jaw, wherein a spacing between a surface element of the punch and the side portion of the outer forming jaw changes. The stamp can be retracted into the space formed by the outer mold jaw. An inserted in the outer mold jaw, flat-extending element is traversed by the stamp. For the formation of a casting mold, the punch can penetrate or extend through the extended element at least in certain areas. The stamp movement takes place in particular in a normal direction, ie at right angles to a surface of a side region. The stamp brings a surface-shaped molding area in the injection mold. Due to the shape of the stamp, a cutout-like segment of a box, such as a window or a recessed grip can be molded into a box surface. During injection molding, the injection molding compound surrounds the molding area of the stamp. The corresponding area remains free in the cast form of the box. For shaping, the punch can be moved by a preset length. Favorable travel distances are in a range of about 0.5 mm to about 20 mm. Before placing the extended element on the outer mold jaw of the punch can be extended over a predetermined distance from the outer mold jaw. This simplifies insertion of the extended element onto the outer mold jaw with the element carrier. A more accurate positioning of the element carrier with respect to the outer mold jaw is possible. The flat, extended element can have a recess through which the area-related shaped body of the movable punch passes. If the traveling punch produces a box or sub-box that can be manufactured with less mass compared to an outer-forming jaw present in a die-less injection mold, it shortens the cooling times, which in turn increases the timing rate and shortens the timing times. In addition, the stamp can support the ejector unit of the Injection molding machine can be used. The stamp supports the pressing out of the finished casting mold, the so-called demoulding. The demolding process is promoted by the stamp.

The accuracy of the injection molding process for a box production can be further increased by the tempered element is supplied to the outer mold jaw tempered. By avoiding thermal expansion effects in the transmission of the flat, extended element, the positioning accuracy can be improved. In particular, the element carrier can be heated to temper the flat, extended element. Preferably, a tempered extended element is placed on the element carrier. The extended element can from a magazine, such as a tempering, with a predetermined temperature of z. B. 20 ° C are removed. A single elongated member is liftable from a stack of flat, elongate members by having a panel support retain a retaining connection to the adjacent flat elongate member, e.g. B. by a vacuum method or a static charging method is formed. The static charging method is based on an uneven distribution of electric charge carriers between the element support and the flat extended element. With the aid of the tempering, the formability of the flat, extended element can be improved, so that a uniform, wrinkle-free support can take place on the element support. A temperature of the label can also be effected by heat, in particular radiant heat from the outer mold jaw. Furthermore, the element carrier may comprise a heater for temperature control of the label. If the flat, elongated element is introduced into the injection mold in the manner described, the transport times for the flat, extended element are to be set with a fraction of the curing times, which in turn leads to an acceleration and thus to an increase in the timing or the firing sequence contributes.

The design variety for boxes, such as crates, can be even further improved and in particular, the stability of a box can be improved by at least one stabilizer spar is introduced into the injection mold of the box. The stabilizer bar is preferably positioned by an element carrier at the corner areas. The stabilizer bar can in particular be inserted into an interior bounded by at least one outer forming jaw. In injection molding, the stabilizer bar is at least partially covered by flowable molding compound. This allows hollow areas in the box or in the sub-box manufacture, which reduces the amount of molding material and increases the rate of clocking.

In the production plant for the production of boxes, the element carrier is automatically moved. At least one element carrier has at least one hydraulic, pneumatic, electrically or purely mechanically actuable actuating cylinder. An element support may also comprise a plurality of similar actuator cylinders or actuator cylinders to be actuated or driven by similar equipment. The actuating cylinder causes a change in length, which is transferred into an extension of the element carrier. The element carrier can, for. B. are spread with a control cylinder in a first direction. The element carrier can be moved with a positioning cylinder in a first direction. Furthermore, it is possible to return the element carrier with an actuating cylinder in an initial position for receiving a flat, extended element. The element carrier can take a first shape, in the z. B. an extended element can be applied to a surface of the element carrier. The element carrier can take a second shape in a second position, which is adapted to a shape of the outer mold jaw. The adaptability of the element carrier makes the support of the element carrier, in particular of the flat, extended element, even more uniform to the outer forming jaw.

The production plant comprises at least one injection molding tool. An injection molding tool according to one aspect has at least two outer mold jaws. The inner mold of the injection molding tool is formed by a core. The core specifies an inner shape of the box. For this purpose, the core is preferably movable in an arrangement with respect to at least one outer mold jaw. A core can, for. B. with an assignment to an outer mold jaw form a mold that includes at least two Eckholme. A core may also be in the form of a quill or spar connecting in the box to the bottom portion of the box or to the wall portion of the box. Another function of the core may be to define a floor structure for a box, such as a honeycomb structure. An arrangement of quills or compartments, which can be specified with a core for a beverage crate, serves for. B. the storage of individual bottles in a beverage container. The bottles are protected from scratching or damage during vibration. The sleeves preferably extend in a cylinder-like manner as shock absorber elements between the bottles.

A beverage box may include hollow body corner posts that improve box stability and reduce the weight of the box. At least two hollow body corner posts may be part of a carrying structure of a box for receiving a large weight. In one embodiment of a beverage crate are the corner posts upright on the bottom surface of the box, with a side wall of the box extending between the corner posts. A flat, extended element is applied to the outer surface of the box. The extended element is in this case materially connected to the molding compound of the box. The extended element is arranged on the box so that at least two hollow body corner posts are at least partially covered. The flat, extended element is a one-piece element that extends over the surface of the beverage box. The extended element is a one-piece element connecting a first side portion of the beverage crate, a second side portion of the beverage crate, and a third side portion of the beverage crate. The extended element can also connect in one piece a first hollow-body Eckholm with a second hollow-body Eckholm. Due to the one-piece nature of the flat, extended element, it has no seams or overlapping areas in which the layer thickness of the extended element is increased and there is a deviation from a flat extent. Edged seams could pose a risk of injury, whereas provision is made in a box according to the invention. The extended element may be formed as a perforated element with holes or flat recesses. The extended element still forms a coherent unit, preferably with a uniform layer thickness over the entire surface. In this way, a fusion with the flow-shaped molding compound can be improved. In each case, there is preferably an opening at a first end and at a second end of a longitudinal extent of the corner pillars. The corner posts are in particular continuous from the bottom of the box to an upper edge of the box. By dispensing with spatial subdivisions inside the Eckholme the weight of a beverage crate can be reduced even more.

The previously described combinations and exemplary embodiments can also be considered in numerous other connections and combinations.

Below, various aspects of suitable production equipment for the production of boxes and sub-boxes by means of injection molding tools are shown in a simplified representation. These can be implemented in conventional production systems in numerous combinations.

1 shows a sub-box 3 , on one of three pages 11 . 13 . 15 circumferential partial surface 45 with a coating 47 is occupied. The coating 47 starts above the area of the ground 19 and extends over the box edges 29 . 31 on the other pages 13 . 15 of the box 3 , Thus, the coating extends 47 from the first box side 11 on the second side of the box 13 to the third box side 15 in a coherent, bum-free manner, that is, continuously. The coating 47 is on the center plane 17 unavailable. The center area 17 serves as a bumper wall, so that a similar box as the part box 3 mirror image of the sub-box 3 can be connected. From individual sub-boxes like the sub-box 3 becomes a Total crate 1 (please refer 2 ) created. The box edges 29 . 31 are by corner posts 33 . 35 strengthened. The corner posts 33 . 35 extend from the ground 19 up to the top of the total drinks box 1 , so the box top 20 , and have a low weight with high stability due to a continuous, hollow cylinder-like structure. The box sides like the box sides 11 . 15 are not continuous, but have openings 37 . 39 , in particular in the area facing away from the ground, ie in the vicinity of the side facing away from the floor 21 , on. The box surface 23 is through the coating 47 designed visually appealing at least in some areas. The coating 47 is cohesive with the casting compound of the sub-box 3 connected. The coating 47 is through the casting mass of the sub-box 3 underlaid; This is due to the fact that the coating 47 from the casting compound during the manufacture of the sub-box 3 has been injected behind. For this purpose, as in 4 better to see the molding compound 240 into the cavity 236 the injection mold or mold 242 with such a temperature, for. B. in a temperature range between 20 ° C and 60 ° C introduced that the bottom or inside of the coating 47 few μm (with a thickness smaller 20 μm) is welded. In addition, there are other protective membranes 51 in the window area 41 . 43 available. The window 41 . 43 serve as grip openings at the same time. The protective membranes like the protective membrane 51 in the window area 41 . 43 are interchangeable to prevent perspiration, hand dirt and signs of wear by removing or replacing the protective membrane 51 to eliminate. From such a replacement action remains the coating 47 untouched, as a specially designed decorative layer, the essential impression of the sub-box 3 taught. The subarea 45 with the coating 47 can still be preserved in the originally created form. It is particularly favorable if the protective membrane 51 superficially as an adhesive layer is present, the coating 47 a component of the sub-box 3 is. The (partial) box 3 has more recesses like the recess 59 , which can also be referred to as Gefache, can be adjusted by the (not shown) bottles or removed from the box. The center area 17 extends from the first edge of the box 25 to the second edge of the box 27 , From the first box edge 25 to the second box edge 27 runs without the center area 17 to touch or part of the center area 17 to be, even the coating 47 but over the box pages 11 . 13 . 15 instead of the short connection plane of the center surface 17 , The coating 47 makes for a pleasing appearance. At the same time, the coating 47 develop a protective function for the box, z. B. against scratches and signs of wear.

Two partial boxes 3 . 5 make up a total box 1 as if in a line of sight from below 2 is shown. The box side 11 thus goes into the box side 11 ' above. The box side 15 goes in the same angular position as the box sides 11 . 11 ' in the box side 15 ' above. The center area 17 is from the outside, more precisely from one direction, starting from one of the sides 11 . 11 ' . 15 . 15 ' , no longer touchable when the total box 1 is compiled. The parallel compared to the center area 17 running outer walls 13 . 13 ' represent the outer limits. Inside, between the box sides 11 . 11 ' . 13 . 13 ' . 15 . 15 ' run quills 57 . 57 ' , Spars or sections 61 , for the attachment of (not shown) bottles in the sense of transport safety part of the box 1 are. When looking from below onto the ground 19 can be seen very well the areas for receiving the (not shown) bottles. At the sub-box 5 is also a formed on the bottom stabilizing grid 63 shown that with little material the rigidity of the structure of the whole box 1 improves and carries the bottles. The stabilization grid 63 is with the quills 57 . 57 ' connected. The stabilization grid extends to the sides 11 ' . 13 ' and 15 ' , As a sub-box 3 can an appropriately trained sub-box like sub-box 5 be used. Furthermore, two sub-boxes, such as the sub-box 3 be combined into a total box. In a more stable embodiment of a box, in particular with a supporting floor z. As for bottles, Sparkegel are dispensable. In further embodiments of beverage crates, a stabilizing grid in the ground can also be combined with recesses for bottles, spars or compartments. The box 1 in 2 consists of two sub-boxes 3 . 5 together, the slightly sloping sides 11 . 11 ' . 15 . 15 ' to have. The slopes of the pages 11 . 11 ' . 15 . 15 ' arise by a Lotfällung on the sides 13 respectively. 13 ' of the box 1 , The pages 11 . 11 ' . 15 . 15 ' close at an angle that deviates from a right angle by a single-digit degree range, to which the two sides 11 . 15 respectively. 11 ' . 15 ' connecting pages 13 respectively. 13 ' at. Only the box sides 13 . 13 ' actually run parallel to each other while the cask sides 11 . 11 ' and 15 . 15 ' in a spanning manner, in other words outwardly extending for a larger center area 17 compared to the areas of the box sides 13 . 13 ' to care. The angle to the outside is so small (it is less than 5 °, preferably only about 1 °), so that for a superficial viewer, the slope or the inclination of the box sides 11 . 11 ' and 15 . 15 ' compared to the box sides 13 . 13 ' not really jumping in the eye. The angle between an outside 11 . 15 respectively. 11 ' . 15 ' and the page connecting these pages 13 . 13 ' is greater than 90 °. The two partial boxes 3 . 5 give the impression of a coherent (total) box 1 , Such sub-boxes 3 . 5 and such a total box 1 can with their bevels and extra-rectangular side layers or Page orientations in the production plants explained below 100 . 200 . 300 . 400 . 500 (please refer 3 to 7 ) getting produced. It is particularly advantageous if the pages 11 . 11 ' . 15 . 15 ' These are the pages 11 . 11 ' . 15 . 15 ' coming from the center area 17 as outsides go away, both to the ground 19 as well as to those of the center surfaces such as the center surface 17 farthest box sides 13 . 13 ' bent at an angle, in particular at an angle greater than 90 °. An attaching the bes chichtung 47 (please refer 1 ) is particularly easy.
