Magnetic standing-up apparatus for can bodies

Abstract

A magnetic can-body standing-up apparatus (Z) comprises an inlet transporting device (10) for conveying lying can bodies (4), a transporting device (12) arranged above the inlet transporting device (10) for conveying upright can bodies (9) hanging on the transporting device (12), and a controller (13). A first magnet arrangement (1) which is activatable and deactivatable in a manner controllable by the controller (13) is arranged below the inlet transporting device (10) in such a manner that a can body (4) lying on the inlet transporting device (10) is magnetically securable in a releasable manner on the inlet transporting device (10). A second magnet arrangement (2) is arranged above a region of the inlet transporting device (10) in which the can bodies are transported and is configured in such a manner that a can body (4) lying on the inlet transporting device (10) can be lifted up by means of the magnetic field of the second magnet arrangement (2) when the magnetic field of the first magnet arrangement (1) is deactivated. A third magnet arrangement (3) is provided above the transporting device (12) and is configured and arranged in such a manner that a can body (4a) which has been lifted up can be lifted up further and can be lifted off the inlet transporting device (10) and can be transported upright hanging magnetically on the transporting device (12). The controller (13) is configured in order to activate the first magnet arrangement (1) when a front edge of a can body (4) lying on the inlet transporting device (10) passes the second magnet arrangement (2) and in order to deactivate the first magnet arrangement (1) when a trailing edge of said can body (4) comes to lie under the second magnet arrangement (2).

Description

[0001] Description of the file [0002] This document claims the priority of Swiss Patent Application No. 0666 / 14 filed on May 5, 2014, for which the entire content is incorporated by reference. Technical field [0003] The present invention relates to a magnetic tank erecting device according to the independent claims and a device for manufacturing tanks comprising such a tank erecting device. Background technique [0004] When the can body is manufactured, after the can leaves the welding machine, the can is directly processed further or the applied seam cover is baked. For subsequent operations, the flat tank is usually placed in an upright vertical position. Tank erectors are known, where this is done by means of a magnetic field. Here, erection usually takes place around the front edge of the tank, so that the rear of the tank moves upward. Known magnetic can standers work with magnet boxes, which are arranged on both sides of the transport path of the can. [0005] An exampl...

AI Technical Summary

Problems solved by technology

[0008] The use of magnet boxes lateral to the transport path entails a series of more or less obvious disadvantages

A disadvantage is that there is an increased risk of the magnet box coming into contact with the conveyed cans, which can lead to damage to the cans

Additionally, such magnet boxes can be difficult to assemble and adjust

In connection with this, the magnet box has the disadvantage that the view into the interior of the device is blocked due to the position of the magnet box, making access to the device difficult

Furthermore, the flight path or erection process of the tank cannot be observed or hardly observed, so that readjustment of the device becomes difficult
