Description

Magnetic erecting device for tank

The present invention relates to a magnet erecting apparatus having a first feed conveyor mechanism for a horizontal tank and a second discharge magnetic conveyor mechanism having a first magnetic mechanism, the first magnetic mechanism being provided for The second conveyor mechanism is used for magnetically suspended erected tanks, and a magnetic erecting device having two magnet boxes forming an intermediate space between them for use by the conveyor mechanism so that the horizontal tank can be fed The suspension can is released from the intermediate space, or the erecting device has a second rod-like magnetic mechanism that is disposed on the second conveyor mechanism in the direction of transport prior to the first magnetic mechanism.

In the manufacture of the can body, after the can body has left the welding machine, it is further processed or the seam cover is directly burned. For subsequent operations, the horizontal can is typically turned into a straight vertical position. A tank erector is known, in which this is achieved with the aid of a magnetic field. Here, the front edge of the can body is usually erected, and the rear portion of the can body is moved upward. A magnet erecting machine manufactured by O.S. Walker Magnetics, Inc. of the United States is known, and its design is as shown in Fig. 1 of the present application. With such a tank erector, the can is always rotated or tilted about its leading or leading edge, and the can is erected using the tail of the can. By arranging the magnets of the individual magnets in a row in a sealed box, a single large magnet is produced. The magnetic field. The can system is placed in the center of both sides of the tank conveyor path with the aid of two magnet boxes, which reduces the risk of scraping the paint on the tank. This solution is applicable to a wide variety of tank diameters and heights and is therefore a versatile solution, however it always uses their tails to erect these tanks. Further magnet erecting machines manufactured by NSM Magnettechnik GmbH of Germany are known which are designed for a dedicated production line in which the tank height and the tank diameter are substantially fixed. The canister erecting machine works with fewer magnets, incorporating fewer magnets to form individually arranged magnetic bars that are placed in a sealed magnet case located on either side of the can conveyor path. An exact location specified. In doing so, the magnetic rod is configured such that the tank erecting machine is not erected solely by the leading edge of the tank, or is constructed by erecting the trailing edge of the tank, so that the operator of the tank manufacturing system must Use a device for erecting one or the other type.

This purpose is for the construction of a magnetic erecting device for tanks, which is suitable as a universal solution in all cases. At the same time, more particularly, the erection direction must be easily selectable.

This object is achieved in that a further magnetic mechanism is disposed under the first conveyor mechanism such that it can be activated and deactivated, with which the horizontal cans can be magnetically held until they have been activated Fully entering the intermediate space, and the horizontal can is released before reaching the end of the intermediate space, or by activating the second magnetic mechanism, the horizontal can is partially magnetic along one of the conveyor paths located below the second magnetic mechanism The ground is maintained on the first conveyor mechanism.

According to the invention, with the same erecting device, the rear portion of the can body can optionally be erected by rotation or tilting around the leading edge of the can body, or the front portion of the can body can be wound around the can body The trailing edge is rotated or tilted to be erected. In doing so, the existing magnetic field of the erecting device is fully utilized for the erection of the two types. The can body can be maintained on the lower conveyor belt, and when it is activated, with the help of the activatable magnetic mechanism until it enters the intermediate space, the combined active area of the magnet and the magnetic conveyor mechanism that has left the magnet device can The erection does not take place with the leading edge, which can occur if the magnetic mechanism is deactivated. Upon exiting the intermediate space, the can has exited the active area of the activated activatable magnetic mechanism as a result of being transported on the first conveyor mechanism and is erected with its front portion by tilting about the trailing edge. In an alternative embodiment without a magnet cartridge, the tank system is maintained on the first conveyor mechanism during a portion of the conveyor path below the second magnetic mechanism of the erecting device by activating a further magnetic mechanism, Its erection is the result of rotation around the leading edge of the can. With the solution according to the invention, the vertical direction of the can body can thus be freely activated by activating or deactivating the magnetic mechanism separately without the need for new magnetic erecting devices or without having to change the alignment of the magnet cartridge or magnet select. The upright direction can be changed very quickly. This leads to a solution to resource and cost savings.

If the activatable magnetic mechanism is formed by a permanent magnetic mechanism (e.g., a magnetic bar) that can be tightly attached and removed, this can result in a short transition time for changing from the upright tail to the upright front. If the activatable magnetic mechanism is formed by an electromagnet, the erecting of this type can be selected by activation or deactivation thereof without actually having a transition time.

Further embodiments, advantages, and applications of the present invention can be learned from the dependent items and from the descriptions that occur now based on these figures.

These figures show an exemplary embodiment of the invention in a simplified diagram. The erecting equipment is used in the manufacture of metal cans, and the horizontally conveyed cans need to be erected using the erecting equipment. After the weld is covered with a coating, the welded can is typically horizontally removed from the appropriate parts of the machine and erected for further processing. With regard to the erection process, the erecting direction is defined as follows: erecting the tail: the horizontal carrying tank rotates around the leading edge in the conveying direction; erecting the front: the horizontal carrying tank rotates around the trailing edge in the conveying direction.

Figures 1 to 3 show an embodiment of a magnet erection device 1 having a magnetic erecting device 5 comprising a magnet arrangement positioned in a tank conveyor path In the magnet box on the side. Such a device is preferred; if desired, a magnet device may be placed only on one side of the conveyor path; a space in which erection occurs may also occur in this case, and for the purposes of the present invention, this is equivalent The space described below (as an intermediate space). In the embodiment shown in Figs. 1 to 3, an intermediate space 17 for the can body is produced between the two magnet cases 15 and 16 of the magnet device, the can body passes through the intermediate space 17 and they are Erected. In Figures 1 and 2, the magnet device of the device is shown by only one magnet case (the magnet case 15, which is disposed behind the conveyor mechanism in the direction of the view above the drawing), and can be placed in the magnet case. The path between the cans and between the cans in the intermediate space can be seen and is not hidden by the other magnet box 16 disposed in front of the view. Figure 3 shows two magnet boxes 15, 16 and an intermediate space 17. Again, the magnetic field lines are shown in Figures 1 and 2, and in each case. Three tanks at different locations are displayed along the conveyor or upright path to show the erection process.

The conveyor mechanism for the tank body is only shown in outline, and the plurality of lines show the transport conveyor used in the examples of Figs. Their drive mechanism is not shown. The conveyor mechanism of the erect apparatus shown is designed to enable the can body to pass from the left into the erect device and away from it to the right in the illustrated embodiment of Figures 1 and 2. Conveyor mechanisms are, for example, conveyor belts well known to those skilled in the art, such as are well known for use in can manufacturing systems. The second discharge conveyor mechanism is a magnetic conveyor mechanism in which the upper tank system is transported in a suspended manner and its magnetic field acts in conjunction with the magnetic field of the magnet box or magnet assembly. In the example shown, the magnetic field of the magnet arrangement is produced by some permanent magnets. Electromagnets can also be used in place of permanent magnets, depending on their design, they can be configured differently than the permanent magnets. In the example shown, the magnetic conveyor mechanism is also designed to have a permanent magnet.

The erection of the can body utilizing the apparatus by tilting the leading or leading edge of the can body and by erecting the rear of the can is shown in FIG. This is the tanks 10, 11 and 12 for explanation. The apparatus as a whole is indicated by 1 and has a first conveyor mechanism 2, which is schematically shown as a driven conveyor belt. Drive mechanisms such as motors, reverse rollers, and support rollers are not shown, but are well known to those skilled in the art. In the drawing, the first conveyor mechanism 2 moves the container can located thereon from the left to the right. Again, the apparatus has a second magnetic conveyor mechanism 3 that is similarly shown as a conveyor belt and similarly has a drive mechanism, reverse roller and support rollers that are well known to those skilled in the art. Furthermore, the second magnetic conveyor mechanism 3 has a magnetic bar or a magnetically shaped mechanism 4 of another shape which, by virtue of their bottom portions, supports an upright can which is suspended from the conveyor mechanism 3 in an "inverted" configuration. The magnetic mechanism can extend over the entire conveyor path of the conveyor mechanism 3 for the tank from which it is suspended, or can be suspended from the conveyor mechanism 3 by another support during the conveyor path after the magnetic mechanism 4 or rod The magnetic retention mechanism of the can is replaced. The magnetic mechanism 4 can be a permanent magnet magnetic mechanism or an electromagnetic magnetic mechanism.

Magnetic erecting devices are generally well known to those skilled in the art and are indicated at 5. This is preferably carried out by means of two boxes 15, 16 comprising magnets on both sides of the conveyor mechanisms 2, 3, whereby the two boxes 15, 16 thus form an intermediate space 17 between them, the conveyor mechanism 2 and 3 are guided therethrough to transport the can between the two boxes with magnets. In doing so, the can system is erected by the magnetic mechanism and transported from the first conveyor mechanism 2 on which the can body is placed to the second conveyor mechanism 3 from which the canister is suspended. In Figures 1 and 2, the box-like erecting device is only shown with a magnet box 15 (which is disposed behind the conveyor mechanism in the direction of the view above the drawing), thereby allowing viewing between the two magnet boxes. In the tunnel or intermediate space 17, the tank runs through the tunnel or intermediate space 17, and the tunnel or intermediate space 17 is shown in FIG.

It can be seen in Figure 1 how the horizontal tank 10 is conveyed towards the tunnel or intermediate space 17 in the erecting device 5. Upon entering the erecting device 5, each can system is erected with its leading or leading edge 7 by means of a magnet that produces the erecting device 5 of the magnetic field represented by the field line 6 and with the magnetic mechanism 4 of the conveyor mechanism 3. As shown in the figure, the can body 11 is followed by It becomes its tail resting on the second conveyor mechanism 3. Each can body is thus erected from a horizontal position and is thus tilted about its leading edge. The illustrated embodiment of the process and erecting device is well known to those skilled in the art and is not further described herein. The erecting device according to the invention additionally has a retaining mechanism 14 for a further magnetic mechanism of the electromagnetic mechanism below or in lieu of the conveyor mechanism 2, as will now be explained with reference to FIG.

Figure 2 shows how the front portion can alternatively be erected in accordance with the present invention whereby the can system is erected by tilting about its trailing or trailing edge 8 so that it can be relied upon by its front or with the edge 7 It is transported on the second conveyor mechanism 3 and again in a suspended manner. For this purpose, a further magnetic mechanism is associated with the first conveyor mechanism 2. This magnetic mechanism can be a permanent magnet bar 9 that can be tightly mounted to the generally shown retaining mechanism 14 below the conveyor mechanism 2 and secured therein. The apparatus according to the invention is thus utilized during the interruption of the operation of the apparatus 1 by means of the introduction of such a magnetic mechanism for the rear edge to be converted for erection. The magnetic mechanism 9 can be introduced and fixed only by sliding the magnet bar into the appropriately formed retaining mechanism 14, which results in a particularly simple changeover. However, a further magnetic mechanism can also be an electromagnetic mechanism that is permanently disposed in the device 1 and that can be operated only by activating its power source. In this manner, the change from erecting the tail to the edge of the leading can body (Fig. 1) to erecting the front with the trailing can edge (Fig. 2) can be achieved only by activating the electromagnet. Figure 2 shows how the can body 10 is not erected into the erecting device 5 in this case, its further magnetic mechanism (here the magnetic bar 9) is prevented, but has been transported horizontally into the first conveyor In the interior of the erecting device on the mechanism 2, and when the can body is no longer held on the first conveyor mechanism by a further magnetic mechanism, it is erected only when it is removed. This can be seen in the case of the can body 11, just by tilting about its rear edge 8, by the erecting device 5 and the magnetic mechanism 4 of the second conveyor mechanism, just removed, which becomes its leading edge 7 It is docked thereon and transported by a second conveyor mechanism in a suspended manner, which is displayed by the can body 12.

Figure 3 shows this embodiment in a view of a magnetic canister erecting device 1 as it leaves in a direction opposite to the conveying direction. The can body 12 is thus visible. Both magnet boxes 15 and 16 and the space between them are shown in this figure. Further, the conveyor mechanisms 2 and 3 are in the form of a conveyor belt. In the case of the lower conveyor belt 2, the display mechanism 14 is shown with a further magnetic mechanism in the form of a magnetic bar 9, as if the conveyor mechanism 2 is transparent, in addition to Figure 2, in order to better display further magnetic mechanisms The location. According to a preferred embodiment, on the top second magnetic conveyor mechanism, the magnetic mechanism 4 is implemented in the form of two magnetic bars 4' and 4" arranged separately from each other. This preferred embodiment has the following effects. The can body 12 is substantially placed in the center of the middle of the conveyor mechanism 3 and does not touch the magnet boxes 15 and 16, which avoids damage to the can body.

Figures 4 through 6 show still further versions of the embodiments in the same pattern. Here, the magnetic erecting device 5' is implemented without a magnet case. Instead, the erecting device 5' of the magnet erecting device 1 has a second rod-shaped magnetic mechanism 18 on the upper conveyor mechanism 3, which is located in front of the first magnetic mechanism 4 in the conveying direction. This second magnetic mechanism 18 is designed such that it can pull individual can bodies (which are labeled here in Figures 4 to 30, and 30 to 36 in Figure 5) to the second. Conveyor mechanism 3. It can be seen in Figure 4 that when the further magnetic mechanism in the lower conveyor mechanism 2 is not activated, this thus causes one of the front portions to erect or erect one of the respective trailing edges 8 of the respective can body. This is not the case in Figure 4 because a magnetic bar 9 is not tightly mounted on the holder 14. In the case of an electromagnet as a further magnetic mechanism, this will be converted to an inactive state. The conveyor mechanism is shown schematically as a rotating conveyor belt, where the drive and reversal mechanisms are generally visible. The same reference numerals are used to designate the same or functionally identical elements.

In Figure 5, we can see that further magnetic mechanisms are activated because a magnetic bar 9 is tightly mounted in the holder 14. This causes the rear of the can to be erected with their leading edge 7 because a further magnetic mechanism (here the magnetic bar 9) compensates for the magnetic mechanism The effect of 18 passes over one of the paths allows the erection to occur only in association with the first magnetic mechanism 4 of the second conveyor mechanism 3.

With a manner similar to that of Figure 3, Figure 6 thus shows a view of the embodiment of Figure 5 viewed in a direction opposite to the direction of transport. However, the display itself is not a visible retention mechanism 14 and rod 9.

Figure 6 also shows here that the first magnetic mechanism is preferably implemented using two rods 4' and 4" so that the respective can bodies are centrally located. This embodiment is also preferably a magnetic mechanism 18 for erecting the device 5'. It is therefore also preferred to carry out the two rods spaced apart from one another in such a way that, in the case of the erection process according to FIG. 4, the tank body here has been placed in the center of the conveying direction.

Figure 7 schematically shows an apparatus for manufacturing a can body. This has a unit 21 in which the can system is rounded from a flat sheet and welded, and then an internal coating is produced. The can body thus formed is then fed into the magnet erection machine 1 by means of the conveyor mechanism 2.

The present invention relates to a magnet erecting apparatus comprising a magnetic erecting device 5 for a tank body, a first conveyor mechanism 2 for feeding the horizontal tank body, and a second magnetic conveyor mechanism for erecting the tank body 3, 4. Alternatively, the can body may utilize further magnetic mechanisms 9 such that their tails or their front portions are erected by means of the device, the magnetic mechanism 9 being configured to enable it to be activated, or in a permanent In the case of a magnetic mechanism, they are separately glued, deactivated or removed.
