Description

The invention relates to a transport unit for transporting and providing a plurality of components.

From the DE 10 2009 004 302 A1 a load carrier unit for the transport of components as well as a transport carriage for the transport of the load carrier unit has become known. The load carrier unit and the trolley are modular, so that the load carrier unit can be adapted to the respective requirements.

An object underlying the invention is to provide an ergonomic transport unit.

This object is solved by the features of patent claim 1. Further advantageous embodiments of the invention are each the subject of the dependent claims. These can be combined in a technologically meaningful way. The description, in particular in conjunction with the drawing, additionally characterizes and specifies the invention.

• – einen Rahmen mit einer ersten Seite und einer zweiten Seite, sowie
• – eine Mehrzahl an zur Aufnahme von Bauteilen geeigneten Trägerelementen, welche übereinander auf der ersten Seite sowie auf der zweiten Seite in einer Hochachse verschiebbar angeordnet sind, wobei die Trägerelemente so in dem Rahmen angeordnet sind, dass
• – ein jeweils oberes Trägerelement in einer Querachse von der ersten Seite zu der zweiten Seite verschoben und ein jeweils unteres Trägerelement in der Querachse von der zweiten Seite zu der ersten Seite verschoben werden kann, und dass
• – auf der ersten Seite die Trägerelemente in der Hochachse nach oben verschoben werden und auf der zweiten Seite die Trägerelemente nach unten verschoben werden.

Accordingly provided is a transport unit for a plurality of components, comprising

• - a frame with a first page and a second page, as well
• - A plurality of suitable for receiving components carrier elements which are arranged one above the other on the first side and on the second side in a vertical axis displaceable, wherein the carrier elements are arranged in the frame, that
• A respective upper carrier element can be displaced in a transverse axis from the first side to the second side and a respective lower carrier element in the transverse axis can be displaced from the second side to the first side, and
• - On the first page, the support elements are moved in the vertical axis upwards and on the second side, the support elements are moved down.

The support members are thus adapted to be moved in linear directions in a circuit. The support elements first perform a lifting movement in the vertical axis, wherein the lifting movement takes place upwards or downwards, depending on which side they are currently located. Components on both the first side and on the second side can be removed from the uppermost carrier element, while the second side can likewise be open, so that the side on which the components are removed can be selected locally. The transport unit can be constructed so high that the top support member is easily accessible by a fitter standing up, so that the components can be removed in an ergonomic manner. The transport unit thus facilitates the installation of numerous heavy components, such as units for vehicles on the assembly line of a motor vehicle production. It can accommodate a variety of components in the transport unit, which can be brought by the linear circle promotion of the support elements always to the same, easily accessible height.

In one embodiment, the transport unit has a coupling device which shifts a lower carrier element in an opposite direction when a respective upper carrier element is displaced.

As a result, the lowermost carrier element does not have to be moved manually before the carrier elements on the first side can be moved upwards on the first side and the carrier elements on the second side can be moved downwards due to the lifting movement. This improves the ergonomics of the handling, since the installer does not have to go to the height of the lowest support member.

According to a further embodiment, the displacement of the support elements in the vertical axis via a first lever is manually initiated.

As a result, relatively heavy components can be arranged in the support elements. By employing a relatively long lever to displace the support members, leverage can be utilized to facilitate displacement. The necessary muscle power can be kept correspondingly low, so that the provision of the next respectively equipped with new components support element can be done easily and ergonomically favorable.

According to a further embodiment, the displacement of the upper support member and the lower support member in the transverse axis via a second lever.

Although the displacement of the carrier elements in the transverse direction can be done manually, the second lever facilitates the displacement of the carrier elements in the transverse direction. Thus, the ergonomics of the transport unit can be further improved.

In a further embodiment, on the frame to achieve the displacement in the High-axis extending belts are arranged, wherein the belts are coupled to each other on one side so that they move parallel to each other and wherein the belts of one side are coupled to the belt of the other side, that they move in opposite directions.

As a result, a uniform movement of the support elements in the vertical axis is achieved. The carrier elements on the first side thus always move in the opposite direction as the carrier elements of the second side. The direction is reversible, so that not only the entire circle must be traversed to achieve an already moved in the downwardly moving side support element.

According to a further embodiment, guide elements with rollers are arranged on the belt, wherein the carrier elements are mounted displaceably on the rollers in the transverse direction.

The rollers facilitate the transverse displacement of the respective upper and lower support elements by reducing the friction between the guide elements on which the support elements rest and the support elements.

According to a further embodiment, the carrier elements on guide pins, which partially engage in a rail and secure the support elements in the transverse direction.

The support elements are not rigidly connected to a means which conveys them linearly in the vertical axis, so that they can be displaced upon reaching the respective uppermost or lowest position in the transverse axis. The means which conveys them linearly may be formed by the already mentioned belts. By engaging in the rail guide pins, the support elements can be secured in the transverse direction, when they are currently not in the upper position or in the lower position.

In one embodiment, the material container further comprises a brake, which is designed to decelerate the carrier elements.

The brake can act on the carrier elements in the transverse axis and in the vertical axis. The brake can be designed so that the displacement of the support elements can be braked, for example, if many components are still located on one side of the material container and the other side is empty. Furthermore, the position of the carrier elements can be fixed via the brake.

In one embodiment, the brake is tightened via a handwheel. The brake can be dosed via the handwheel. When equipped with many components and unilaterally loaded transport unit, a high braking force can be adjusted to secure the support elements.

Some embodiments will be explained in more detail with reference to the drawing.
