Description

The invention relates to carrier inserts for shipping packaging, in particular for impact and surface protected recording of packaged goods, such as vehicle parts, electrical or electronic equipment and components.

To safely transport equipment and components to be shipped in pallets, boxes or other transport containers, packaging inserts of different shapes and materials are known. It is important that the packaging and the included tray inserts should be as light as possible. Furthermore, it is important that the packaging containers have such carrier inserts which, despite their low weight, have the highest possible stability in order to ensure a secure and stable transport of the components contained.

Are known racks of sheet materials such as wood, corrugated cardboard and cellular sheets or foam and plastic toothed strips, which are inserted or fixed in the transport container. The racks usually have recesses that can accommodate the components to be shipped.

The disadvantage of toothed racks made of materials such as corrugated board, hollow panels or wood are their hard front sides, which can not prevent both surface damage to the male parts as well as damage from shock or vibration. Foam and plastic toothed strips, however, are comparatively material-intensive and expensive.

Also known, for example, shipping inserts that are made of full-surface materials, and in which the negative forms of the parts to be transported are recessed or formed.

In DE 36 26 765 C2 Such a solution for packaging small parts is described. The packaging body is multi-layered. It has a non-deformable base plate and an elastic, with the base plate firmly connected, thermoplastic deformable support layer. The base plate may be, for example, corrugated cardboard laid over its entire surface. For packaging, the carrier layer is heated to a temperature between 70-180 ° C and the small part pressed into the heated support layer so far that the small part is held securely.

DE 40 22 790 A1 describes, for example, a packaging solution for small engines, consist in the floor and roof wall elements made of rigid, self-supporting foamed plastic. These plastic elements contain recesses for receiving the motors.

In DE 41 15 773 A1 has a packaging a holding plate made of cardboard, on the cushion parts of foam material are detachably arranged. The upholstery parts have mutually swept recesses for positive reception of the devices to be transported. For larger devices, the upholstery parts must be designed to be voluminous in order to derive the entire weight on the holding plate.

US 53 39 958 A describes a carrier insert in which a continuous surface element is 3-fold folded so that it forms a standing on the top, closed triangular body, which is not on the bottom of the shipping container stands up and thus can not derive the loads to be included on the shipping container. The carrier insert is suspended laterally by means of a flap. The entire carrier insert is unsuitable for heavy parts, since it is not intended for load-bearing, but only during storage or transport to prevent easy contact with the parts to be transported and ensure compliance with the distances.

In DE 103 10 197 A1 a device for receiving objects is described, which has a support strip with transversely extending recesses. In these recesses, a flexible band of leather, plastic film or micro fiber fleece is hung, which does not touch the bottom of the recesses. Damping is thus achieved by the floating belts. To support the flexible bands, the support strip has latching points, into which pins or sleeves are inserted and whereby the strips are clamped. The support strip is over its entire width a solid material made of wood or plastic.

In the DE 11 53 677 B a demountable slatted frame is described. The walls of the frame are upright wooden slats B. The parts to be transported lie on the support surfaces resulting flattened slats A. The wider support surface is a safe support. A padding does not take place.

The object of the invention is the development of carrier inserts for a shipping container, with the sensitive equipment and components are protected against mechanical damage. The packaging should be light and easy to make and use. She should be special characterized by a high static and dynamic load capacity. Furthermore, the carrier inserts should be suitable for repeated use or enable worn packaging to be re-used with little effort.

According to the invention the object is achieved by the features of claim 1. Ausgestaltende features are described in the subclaims 2 to 16.

The carrier inserts according to the invention consist of a stable frame substructure and of padding elements made of damping materials, on which the parts to be transported rest. The frame substructure consists of at least two upright and spaced surface elements with high edge crush resistance. The padding elements rest on the end faces of the surface elements. The padding elements have frame-side molded pins or recesses. The surface elements in turn have to the pins or recesses of the cushion elements corresponding recesses or pins.

The carrier insert rests on the bottom of the shipping container and will in most cases fill it completely.

In order to obtain a shipping container which is closed on all sides, a carrier insert which images the top and bottom geometry can form the cover of the shipping container. As a result, the packaged goods can be held on all sides positively in the carrier inserts and transported.

It is also possible to arrange several carrier inserts one above the other and to form a multi-layered shipping unit.

To keep the carrier inserts mutually and zu.positionieren, the frame substructure has longitudinal and / or transversely arranged additional surface elements, which usually consist of the same materials as the surface elements for the upholstery elements. The additional surface elements are inserted or clamped in other surface elements arranged in one or both sides, corresponding slots and thus hold each other.

Between the longitudinally and / or transversely arranged additional surface elements, there may be additional upholstery elements which are inserted or clamped into upholstery recesses in the additional surface elements. These additional upholstery elements serve the additional support of the packaged goods and in most cases do not have to absorb loads as high as the doubly supported upholstery elements.

In order to firmly position the cushion elements on the surface elements, the transversely arranged additional surface elements in the region of the cushion elements can be somewhat higher than the surface elements of the cushion elements. This prevents lateral slipping out.

If the pins of the padding elements are larger than the corresponding recesses of the surface elements or vice versa, if the pins of the surface elements are larger than the corresponding recesses in the padding elements, then both corresponding moldings are held firmly together due to the compressible padding materials.

The pins or recesses of the padding elements and the corresponding recesses or pins of the surface elements may be formed profiled so that they form a non-self-releasing, positive and / or non-positive connection.

For flat upholstered elements, these can be easily adapted to the shape of the end faces of the surface elements and fixed there due to their flexible design. For thicker upholstery elements or upholstery elements with a greater inherent rigidity, the upholstery elements with the underlying surface elements may already have the shape of the male packaging parts.

The frame substructure will be made of materials with suitable edge crush resistance. Suitable materials are corrugated cardboard, cardboard, wood, metal or plastic. A preferred embodiment is the use of polypropylene cellular sheets.

For additional fixation of the padding elements on the end faces of the surface elements, these can be glued.

As upholstery elements in particular foams are used. These may consist of polyurethane (PUR), polypropylene (PP), polyethylene (PE), sponge rubber, sponge rubber, latex, melamine resin, viscose, PVC, copolymers, electrically conductive or antistatic foam.

The upright and spaced surface elements for receiving the upholstery elements can also be formed by a horizontal or upright U-profile. When standing U-profile padding elements are not directly on the end faces of the surface elements, but on the central web of the U-profile, whereby the padding elements also need not extend over the entire width of their webs. Without the central web of the U-profiles, the cushion elements should be at least as wide as the outer distance of the surface elements. Within the carrier insert, differently shaped cushion elements can receive differently shaped shipping parts in a form-fitting manner.

The carrier inserts according to the invention are particularly suitable for shipping packaging with which sensitive equipment and components must be protected against mechanical damage. The carrier inserts combine the high edge crushing capacity of the sheet materials with the scratch, impact and vibration protection properties of foams or plastics, where only foam material or plastic material must be applied at the points where appropriate protection by the contact surface of the protective packaging material is required. The packaging is very light. They are easy to make and use. Furthermore, the carrier inserts are well suited for repeated use. In the case of multi-way packaging, the wear-resistant upholstery can be easily exchanged if necessary without the need for special tools.

The invention will be explained in more detail by exemplary embodiments.

For the shipment of electric motors from an automotive supplier to an assembly company, these are to be combined into packaging units of 100 pieces each in a shipping container and transported safely. 5 layers of electric motors of 5 x 4 pieces per layer are packed in this shipping box made of corrugated cardboard and uncrosslinked PE foam. Each electric motor is about 6kg heavy. According to this, the lowest support used has a static load of more than 480kg and almost 1 ton of dynamic load during transport.

In Fig. 1 a carrier insert for such a shipping container is shown. The carrier insert consists of a sturdy frame substructure, which must accommodate the entire loads of the superimposed in 5 layers engines. In the present example, the frame substructure consists of two surface elements 1, each of which is edgewise and spaced 50 mm apart. The material used is double-walled, 6 mm thick corrugated cardboard cut into stripy contour. According to the contours of the motors to be shipped, the individual strips are brought into such a shape that their end faces have the shape of the male motors. The individual corrugated strips have at intervals of about 100mm recesses into which pins 3 are pressed by cushioning elements 2 made of foam in a simple manner. The approximately 15mm thick and 62mm wide cushion elements 2 adapt very well to the contours of the end faces of the surface elements 1. The poster elements 2 can be very easily manufactured by the meter and cut on site and used universally for various packaging products.

To the two in Fig. 1 shown padding elements 2 on their respective surface elements 1 to each other and within To position the shipping container, between them additional surface elements 5 are installed from the same corrugated board material. For this purpose, the surface elements are each cut in half and the slots 7 inserted into each other. If the additional surface elements in the region of the intersection are low enough, it is also sufficient if only one side has a corresponding slot 7.

In order to position the cushioning elements securely on the end faces of the surface elements and to prevent them from slipping sideways, the additional surface elements have a shoulder 9, the additional surface elements 5 being approximately 5 mm higher than the surface elements 1 in the crossing region.

In Fig. 1 the right pad element 2 is shown prior to installation and the left pad element 2 in the already installed state.

For additional support of parts of the electric motors can be in the surface elements 1 cushion recesses 8 are inserted into the additional cushion elements. The about 20mm wide and about 40mm high additional upholstery elements are in Fig. 1 not shown.

In each layer is a carrier insert, which completely fills the shipping container. Between the individual layers are double-carrier inserts, which have on their underside and at the same time on their upper side the contours of the motors to be shipped and can accommodate them. The upper end is the negative of the illustrated carrier insert, on which then the lid of the shipping container is placed.

In Fig. 2 is a similarly constructed carrier insert to see. The padding elements 2 are preformed in this example, however, already in the form of male motors. In the Fig. 2 apparent pin 3 are formed drop-shaped. However, since the foam used is very elastic, the pins 3 can be very easily pressed into the recesses 4 of the surface elements 1. An independent release is excluded.

Fig. 3 shows a variant in which the pair of surface elements is formed by a plastic U-profile 6. In the middle web are the recesses 4 for the pins 3 of the cushion elements. 2

Fig. 4 shows a flat additional element 10 made of polypropylene cellular sheets. It has recesses 4 for pins 3 of the upholstery elements 2. The illustrated pins 3 allow due to the flexibility of a particularly moldable foam, such as crosslinked polyethylene foam, a further variant of a positive connection. Thus, in several layers, the pin 3 does not hinder the respective overlying layer, 2 notches 11 are provided in the cushion elements. Such additional elements can be placed in addition to free places of the shipping containers.

In principle, such a shipping package is of course also suitable for other shipping goods.
