Abstract

An apparatus for positioning, handling and conveying structural parts for a surface finishing of the parts comprises frames arranged successively in a conveying direction, hooks carried by the frames for hanging the structural parts, and devices for maintaining successive ones of the frames in the conveying direction so close to each other that the structural parts hanging on the hooks are locked in position by the successive frames.

Description

The invention relates to an apparatus and a method for the storage, handling and transport of components for surface finishing, e.g. in the immersion bath during hot dip galvanizing, during painting or powder coating, the components are mounted on a frame.

To perform a surface refinement of various components, such as rod or flat material, there is a loose transport or transport lying on pallets or in storage or special racks. The components then have to be hung by the refiner, usually manually, in devices. For technical reasons, the suspension is usually overhead or in confined spaces. Typical hanging devices are hook systems on conveyor chains and hook or wire fasteners on trusses or special racks. An automatic handling at the refiner is usually too expensive and requires a high degree of specialization, which only pays for itself with very high quantities and high part equality. Under certain circumstances, several different finishing processes may be required, which require an additional transfer or regrouping of the goods. After refining, the goods usually have to be removed manually and then made ready for dispatch.

From US-A-2 196, 633 racks for manual immersion of objects to be coated in immersion baths are known, which have a frame with a plurality of transversely extending transverse members, on each of which a plurality of adjacent hooks is arranged, to which be suspended to be coated components. To juxtapose adjacent racks in a dip prevent the racks are provided with spacers, which are supported on the cross members in the lower and upper region of the racks, and prevent the direct attachment of the components of two adjacent racks.

The invention is based on the object that an initial loading of the system and final removal from the system by simple means manually or automatically, horizontally
or can be done vertically and in this case the components to be treated are automatically locked in the system.

This object is achieved according to the invention by the features of claims 1 and 3.

Technically, the object is achieved by the features of claim 40 and 42.

Advantageous embodiments of the invention will become apparent from the dependent claims.

The system according to the invention allows horizontal or vertical loading and unloading of products, it can be compressed for transport and for Tauchbadveredelung on typical Bad- or container sizes and is self-locking. The locking of the profiles is mainly used for transport safety, for example in truck containers, the oblique pulling and securing during galvanizing. When galvanizing the steel threatens to swim up in the zinc bath and to break out of the hook. The system allows
good accessibility from above for a hot dip galvanizing, it can be singled for quality control or painting easy, it is manipulated with a crane or forklift and it can be stored in passable pallet racking or in containers in several levels one above the other, with the suspended components can be pulled diagonally. For transport, for reloading or for a dip refining, the products can be portioned in large numbers in a high packing density and securely locked. Long and heavy or delicate products can be pulled at an angle and do not need to swing freely. For hot-dip galvanizing, the system is accessible from above through scrapers. For painting or powder coating, the components are easy to separate automatically, so that the components are then freely accessible laterally. The surfaces and masses of the system, which are directly involved in the refining process, are low and may need to be well protected. The hook system is easy to procure and may be made of high quality materials such as titanium or stainless steel and is well suited for automatic cleaning. The cross-beam has a large distance to the bath surface or to the refining process. The receiving and functional surfaces of the system allow easy loading and unloading of the trusses with crane systems, stackers and machines. Furthermore, these allow a simple transport on transport chains, a Staufördern, a separation, a rotation about the longitudinal axis and a rotation about the vertical axis. The trusses can be stored in passable pallet racks. The system is flexible and, with one embodiment of the hook system, accommodates various profile lengths, widths and depths. It is suitable for profiles, pipes and solid material.

The invention will be explained in more detail in the following description with reference to exemplary embodiments illustrated in the drawing.

Fig. 1 shows a first embodiment for the formation of a frame 1, can be supplied to the individual components suspended a refining process. The frame consists essentially of two parallelepipedal side blocks 6, on which lateral struts 7 are arranged, which are directed vertically downwards in the starting position, the ends of these lateral struts 7 being connected by means of a transverse shaft 8. At this cross-shaft 8 at intervals hooks 4, 5 are attached to which then individual components are mounted. The dot-dash line indicates the level 27 of a finishing bath through which the frame 1 is towed. For handling the frame 1, grooves 10 are provided on the side blocks 6 on the inside. This embodiment is particularly intended for lightweight components, since the support frame of the frame 1 has no particularly high stability.

In the case of the further embodiment of the frame 1 shown in FIG. 2, the stability is improved insofar as the two side blocks 6 are connected by means of a crossbeam 9, the lateral braces 7 being fastened to the crossbeam 9.

The embodiment of the frame 1 shown in FIGS. 3 to 5 is further reinforced by being arranged between the cross-member 9 and the transverse shaft 8 between each hook 4, 5 a strut 11 is arranged. Seen in or against the towing direction 6 pins 14 are attached to the side blocks, which have a conical tip with a paragraph 17. These pins 14 engage in a storage promotion in receiving holes 16 of the following frame 1, as shown in Fig. 6. Furthermore, located between the cross-beam 9 and the side brackets 6 internal shaft elements 38, which allow rotation about the traverse longitudinal axis. The crossbeam can also be advantageously designed as a solid shaft or as a tube in this regard.

The total length Lt of the traverse 9 is preferably 800 mm or 1200 mm or 2400 mm. With Rq, the distance of the struts 11 and designated Ht the height of the traverse 9. Furthermore, the width of the traverse Bt, Bb is the width and Lb the length of the side block marked. Hb is the height of the page block.

In a storage promotion of two racks 1, as shown in Fig. 6, results in a grid spacing Rt and a gap width St for the Badabstreifer.

In the further embodiment shown in Fig. 7, the individual hooks 4, 5 are arranged directly at the end of the struts 11 and the individual struts 11 are fixed to the transverse shaft 8. This embodiment is very stable, with no torque being transmitted to the transverse shaft 8. On the lateral struts 11 are directed outwards, and optionally below or above the bath level 27, lateral projecting camshaft 37 attached, which can be performed on a curved path or casserole elements, so that the angle of inclination of the traverse can be adjusted about the longitudinal axis.

In the further embodiment according to FIG. 8, the hooks 4, 5 have no transverse shaft 8. This embodiment of the frame 1 is e.g. suitable for flat profiles.

Fig. 9 shows the arrangement of a thin-walled U-profile as a component 2 with the rear wall 39 in the hook 4 hanging, wherein the hook 4 has a shortened leg 12. The struts 11 of the support shaft of two successive racks 1 are offset and the longitudinal grid spacing Rt is selected according to the leg length of the profile. The transverse grid spacing Rh results from the profile width plus the game. In this embodiment, both a positive and a negative swing angle A is possible. The embodiment is also suitable for open and closed profiles, but not for flat material. With an approximately horizontal end of hook also solid material can be processed. The Einhängungspunkt 13 on the profile 2 is lowered, wherein in the accumulation promotion (Fig. 10), the profile 2 is supported on the transverse shaft 8.

The embodiment shown in FIGS. 11 and 12 differs from the previously described embodiment in that only a positive pivoting angle A of the profile 2 is possible and this embodiment can only be used for open profiles, eg U-profiles, angle profiles and the like. With S the release play of the hinged product 2 is marked on the hook 4 until the next stop.

In Figures 13 and 14, another hook shape is shown, wherein a transverse shaft 8 is not provided for connecting the individual hooks. The hooks 5 have an enlarged length of the leg 12, which extends beyond the strut 11 of the subsequent frame 1. This embodiment is suitable, for example, for thin-walled U-profile as a component 3 with a rear wall 39, wherein the component 3 is mounted at a high hooking point 13 on the hook 5. The longitudinal grid spacing Rt is selected according to the leg length of the profile 3. The transverse grid spacing results from the profile width and the game. In this embodiment, a positive and, to a certain extent, a negative swivel angle A is possible. This embodiment is also suitable for flat material. The component 3 is prevented by the relevant strut 11 of the following frame from falling out.

Figures 15 to 17 show an embodiment of the frame in which the side block 6 is provided with a pointing in or against the conveying direction pin 14 having a conical tip 17 with paragraph. Furthermore, located in the side block 6 with the pin 14 in alignment with a receiving bore 16 into which the pin of an adjacent frame can engage. Furthermore, the lower surface of the side blocks 6 is suitable as a wide outer surface 26 for a two-lane chain conveyor system.

Figures 18 and 19 show two adjacent racks 1, which are spaced by means of a spacer sleeve 19, which may be slotted or closed.

In the embodiment shown in Figures 20 to 22, the side block 6 has a rectangular passage in which a narrow rectangular pin 15 is mounted. This consisting of flat iron pin 15 has at its top 20 a fuse strip 21. About this pin 15 are U-shaped spacers selbstklemmend pluggable (Figures 23 and 24), which have a clamping pin 28 at its opening. With Ld the length of the spacer 22 is designated. For rotation about the traverse longitudinal axis outboard shaft elements 29 are provided.

In the embodiment shown in FIGS. 25 and 26, a torque support 23 is achieved over a large side block height Hb. Furthermore, the side blocks 6 are provided with outboard shaft members 29 for rotation about the traverse longitudinal axis.

A further embodiment of such a torque support 24 results in the embodiment of Figures 27 and 28, wherein the outer struts 7 have a protruding nose 25 at hook height.

The embodiment of a side block 6 shown in FIG. 29 essentially consists of two L-shaped supports 32, the horizontal legs 42 of these supports 32 projecting laterally. The upper support 32 thus forms laterally inside a receiving groove 10, in which the pliers of an inner hook 31 can engage. The interior of the side block 6 forms a forklift pocket 33. Laterally, a side shaft with collar 35 is attached to the outside of the pivoting of the frame about the cross-beam 9. The cross-beam 9 can also be designed as a solid shaft or tube, whereby side shafts 29 and side shafts with Federal 35 omitted. Furthermore, a sidebar 41 is attached to the leg 42 outboard, on this side paragraph a side shelf is created in the clamping elements, such as ropes, chains, wires and rods for lashing the first can be loaded with the last traverse. The upper surface 40 of the side block 6 may be configured as a custom surface, such as the attachment of holes, threads, eyelets, pockets or the like.

The jam-promoted trusses can be secured in the gripper by inserting separate empty racks at the beginning and at the end of the jam section, which have, for example, a widened horizontal leg 42 and preferably jam with the gripper 31. This effect can be further improved for example by a toothing in the clamping surfaces.

The embodiment according to FIG. 30 shows a traverse 9, which is received with an adapter plate 43 for a stacker with stapler pocket 44. The adapter plate 43 can be retracted frontally into the receiving groove 10 of the trusses. However, it would be advantageous to use an example hydraulically operated inner gripper.

Figures 31 to 36 show the particular advantages in handling with a hook system, for example, according to the figures 3 to 5 based on U-profiles. Here, as shown in FIG. 31, the hook system for receiving a profile row with the hook tips is positioned directly under the receiving holes. FIGS. 33 and 34 show how, by means of a simple vertical movement, the U-profile 2, 3 can securely hang and can be brought into the vertical.

In Fig. 35 a towing of the U-profile 2, 3 is shown, wherein the traverse 9 is received drehbeweglieh on the upper side shaft 29. Due to the tilting of the traverse 9, the U-profile 2, 3 is held securely and can be slid horizontally. In the stored tension-free state of the hooks 4, 5 can be unscrewed from the profile 2, 3.

If U-profiles 2, 3 are nested in one another, then dragging and horizontal laying down of the U-profile 2, 3 with the rear wall 39 upwards makes sense. The traverse 9 is rotated before the towing process by 180 ° about the vertical axis. Fig. 36 shows this towing process. Due to the geometry of the profile 2, 3 is securely blocked between hook 4, 5 and transverse shaft 8 and can not fall out, the tilted cross member 9 keeps the hooks 4, 5 always under tension. The hook can be unscrewed when the component 2, 3 rests.

The side blocks can be arranged, for example, inclined inwards or outwards so that sprayed or condensed bath liquid can drain in a defined manner; In addition, venting and drainage holes can be installed.

According to the embodiment shown in FIGS. 37 and 38, a sealing element 36 is arranged below the cross-beam 9, with the cross-pieces 9 sealingly engaging with the sealing elements 36 in the event of accumulation of accumulation. The seal can be done with simple sheets, labyrinths, with sealing lips and the like.

In the embodiments shown in Figures 39 to 51, a good acidity is ensured, which is advantageous for dealing with aggressive media.

The Ausführungsfom of the device shown in Figures 39 to 42 has on both sides of a side block which is formed in cross-section Z-shaped. This Z-shape consists of a vertical leg 52, an upper inboard horizontal leg 59 and an outwardly directed lower horizontal leg 60. Inside the vertical leg 52, the cross-beam 9 is attached. Furthermore, 60 pins 48 are arranged offset on the horizontal leg, wherein in the jam-conveyed state (Fig. 42) these pins 48 receive the torque. A lashing for the jam-promoted state is carried out by a separate element that holds the individual racks 1 in a suitable manner. This can be done with the help of rods, wires, chains, ropes and the like.

In the further embodiment illustrated in Figures 43 to 46, the side block 6 "is L-shaped and has a downwardly directed vertical leg 55 and an upper inboard horizontal leg 56. At the bottom of the vertical leg 55 is the crossbar 9 fastened and furthermore a transverse pin 47 is arranged at a distance from the vertical leg 55 between the horizontal leg 56 and cross-beam 9.

Through the thus formed opening 54 is a safety shaft 46 can be plugged, which is pushed through in the conveying direction 53 for the stowed conveyed state adjacent frames 1 (Fig.46), to secure the shaft 56, this a head 51 and an end plate 49 with Locking pin 50 has. Through this safety shaft, the necessary torque absorption takes place, that is, the safety shaft 46 serves as a torque arm, as lashing element and secures the individual racks against unintentional release.

Figures 47 to 49 show a further variant for the formation of the side block on such a frame, wherein the side block 6 "'has a round tube 57 on which a horizontally extending flat iron 58 is welded .. The cross-beam 9 is fixed to the inside of the round tube 57 The securing shaft 46 runs through the bore of the round tube 57. For better acid removal, the round tube 57 can be provided with drainage bores and the flat iron 58 can also be dispensed with if an external gripper is used for receiving.

FIG. 50 shows the side blocks 6 '"in the jam-conveyed state, wherein a screw connection can also be selected as a modification of the safety shaft shown in FIG.

In the embodiments shown in FIGS. 52 to 59, longitudinal locking, transverse locking and torque absorption are made possible simultaneously by vertical insertion, so that subsequent securing of the traverses is not required.

The embodiment of the device shown in Figures 52 to 55 has on both sides of a side block which is formed in cross-section Z-shaped. This Z-shape consists of a vertical leg 52, an upper inboard horizontal leg 59 and an outboard lower horizontal Leg 60. Inside the vertical leg 52, the cross-beam 9 is fixed.

On the upper horizontal leg 59 includes in the opposite direction to an arm 61 which is laterally directed away from the side block 6 ', wherein at its end a vertical locking pin 62 is mounted. At the lower horizontal leg 60 of the side block 6 ', a vertically aligned sleeve 63 is arranged.

In jam-conveyed frames (FIG. 55), the socket pin 62 of a frame is inserted into the respective sleeve 63 of a subsequent frame 1, so that the individual transverse members 9 are locked together by vertical insertion.

In the further embodiment according to FIGS 56 to 59 is located near the lower end of the lateral struts 7 another arranged on an arm 64 pin 65, wherein on the strut 7 laterally a perforated plate 66 is arranged in stowed frames 1 of the locking pin 65 a Frame engages in the perforated disc 66 of a subsequent or preceding frame (Fig. 59).

In this embodiment, the arm 61 'on the vertical leg 52 of the side block 6' is arranged and the vertical plug pin 62 'shortened. At the lower horizontal leg of the side block 6 ', a correspondingly shortened sleeve 63' is arranged. In this embodiment, the locking thus takes place both in the region of the side blocks 6 'and in the region of the transverse shaft 8.
