DE3116335A1 - Apparatus for the bundling and tying of tubes - Google Patents

Abstract

The invention relates to an apparatus for the bundling and tying of elongate articles, especially tubes and rods, which are lifted out of a collecting trough, shaped to form parcels and, tied by tying means, transported further to a collecting point. In order to save means of transport and transport stations, whilst ensuring the least possible transport delay, the tube bundles are extracted from the collecting trough by means of a tong manipulator which, simultaneously with the transport function, by means of a truss former integrated into its gripper tongs, carries out the shaping of the tube bundles to form a solid parcel and carries this parcel in a stepped longitudinal movement past a tying machine which, after each step, moves into the tube bundle and ties it with a tying means, after which the tong manipulator deposits the finished tube parcel for transfer to a collecting device.

Apparatus for bundling and tying pipes The invention relates to a device for bundling and tying elongated parts, in particular pipes and rods, - which are lifted out of a collecting trough, formed into packages and by means of Tied binding agents are handed over to a collection point. The tube bundles are grasped with the gripper tongs of a tong manipulator and removed from the trough, whereby the forming is integrated into the gripper tongs during transport make the tube bundle to the fixed package and then this package in a step-by-step manner Longitudinal movement is carried past a binding machine.

This binding machine moves into the tube bundle after each transport and binds it with a binder. The tong manipulator transports that finished tube bundle to a collecting device.

Bundling devices as such are known. Wherever there are pipes are collected in collecting troughs at the end of a work cycle, they must be collected using suitable Means of transport, such as cranes, are lifted out of the troughs. Should they are combined into packages in order to facilitate the subsequent transport, you have to tie them together. The main binders are wire and steel strip. That Binding is done by hand or by known binding machines. To a solid package to get out of the pipes in transit do not slip out, the tube bundles must be pressed together as closely as possible before they are set and assume a bindable form. Bund formers are used for this purpose. That are known devices in which, for example, hydraulically operated by pressing Fittings or by pulling the bundle together using chains, straps or ropes the corresponding solid packages are formed. This type of fret formers is in the writings DT PS 1 511826, GB-PS 1,358,472 Soviet copyright certificate No. 391013 v. 1972 and DE 28 36857 B2 insofar as they relate to fittings and according to DT 27 12 950 Al, DE 27.47.410.8-27 and DE 27.47 410.8-27, which focus on the collar forming relates to an elastic shaper, shown and known. Binding machines are described in the application DT 15 11817 C3. All known fret formers have the disadvantage that they get the material fed from above and -with it in combination are unusable with a pincer gripper. The known binding machines are alone not the subject of the application according to the invention. The known devices are placed inside the collecting trough, in which the bundle is also preformed, used.

Either several binding machines can be attached to the bundle at intervals be brought up in the hollow to make the binding, to the package or it individual binding machines can be moved laterally from binding point to binding point procedure to make multiple bindings. Because of the binding in the collecting trough the spatial conditions often the retraction of. Binding machines difficult and on the other hand, the collecting trough during the binding and emptying process against subsequent ones Pipes must be blocked, which leads to delays in the process, the collar forming and binding partly outside of the collecting troughs in special stationary Made bundling and binding stations into which the tube bundle is then transported Need to become.

The invention is based on the general object of tube coils To remove collecting devices, to form them into solid bundles and as packages to tie off in order to hand them over to a collection or conveying facility. this also corresponds to the task the known devices. However, the invention is based on the specific task of this process to transfer to a single means of conveyance, with the slightest transport delay a saving of means of transport and transport stations as well as a saving made possible by binding machines. This was due to the easy accessibility of all devices the operational safety and ease of maintenance of the required equipment to optimize.

This object is achieved according to the invention in that as a means of transport A tong manipulator between the collecting trough and the collecting station for the finished packages is used, the different, so far.

Functions to be carried out individually are oversized. First lift his grippers the bundle out of the collecting tray. Strapping the bundle in the hollow for Removal by crane is not necessary due to the shape of the grippers. This is the collecting trough is free again in a very short time and can pick up new pipes. While The tong manipulator also fulfills the removal from the collecting trough and at the same time the task of the fret builder. Into the gripper tongs of the tong manipulator integrated bundle formers firmly hold the bundle together. The tong manipulator carries meanwhile this bundle in front of a stationary binding machine, which is in the longitudinal direction and the height can be approached precisely. The binding machine moves over the tube bundle and ties it off. After binding, the tongs manipulator moves the bundle one step lengthways to the next binding point and so on until all necessary bindings have been made. The tong manipulator then delivers the finished package to the collection device, which collects it for further transport, or it is transported to a conveyor that passes it on.

The next binding transport process then takes place.

Advantages of the device according to the invention are: The rapid emptying the collecting trough with the grippers of the gripper nanipulator.

These make it unnecessary to put chains and straps around the tube bundle in the collecting trough by hand, thereby saving crane waiting time. the During this process, the necessary blocking against additional pipes is made as short as possible Time limits and thus does not disturb the flow of material. The bundle hangs in the Grippers that preform it that way. The bundle formers integrated in the gripper tongs shape it into a solid package shape during transport. This becomes the fret form given in a simple way and the difficult arrangement of fret formers within of the trough area is omitted.

If a separate federal formation station were to be provided, this would be the case additional stations and additional transport processes are necessary here, too are saved. The hanging tube bundle is better placed in a collar shape than the bundle lying in a basin.

Opposite several stationary binding machines on a collecting trough, the device according to the invention has the advantage of only having a binding machine for needing multiple ties. The arrangement according to the invention leaves a freer one structural design and easier operation and maintenance of the binding machines to. A single binding machine would be provided on the collecting trough, the lengthways is flexible and allows multiple ties at different points on the bundle, so the advantages mentioned would also apply to the device according to the invention to. If a collar forming and binding device is connected downstream of the trough, then additional transport operations and transport times required. According to the suggestion these do not apply to the invention. The previous opening of the known devices for removing the bundle after - forming the bundle or pulling out the bundle from the bond former is also omitted. By combining the transport process and fret forming and tying in the same device according to the invention there is a significant reduction in the load on the hall cranes, which would otherwise be necessary for this constant, short, continuously recurring process would have to be used. Another The advantage of the device according to the invention is that the entire process is automated is and is proqratrrniertxr. In the drawing, the invention is based on an exemplary embodiment shown.

The collecting trough (2) are individual pipes (1) by a cross conveyor (3) until the collecting trough (2) has filled, as in Figure 1 shown. Figure 2 shows the filled collecting trough, the stopper (4) locks the inflow of new pipes, the gripper manipulator (5) lowers with the gripper tongs open (6) to grasp the tube bundle in the collecting trough (2). The covenant former is shown here by its two loose bands (7) and (7a), which are when lowering of the grippers over the tube bundle. Figure 3 shows how after closing the gripper tongs (6) the tong manipulator (5) lifts the tube bundle (2). Simultaneously The two straps (7) and (7a) are tightened by means of a winch in the tong manipulator of the bundle former and form the tube bundle according to their arrangement in the grippers (6) to the closed covenant. Figure 4 shows how the tong manipulator (5) with the tube bundle moves on its track (8) in the longitudinal direction and it is in a binding position moves the extended binding machine (9).

Figure 5 shows the retracted binding machine (9), which is the binding process undertakes. After this binding process, the binding machine (9) moves back to its starting position.

The tong manipulator carries the tube bundle around any, before defined or programmed step in the longitudinal direction. The binding machine repeats the binding process and the game repeats itself depending on the intended Number of ties.

Once all bindings have been made, the tong manipulator transports (5) the finished package as Figure 6 shows to a transfer or collection station, where it is filed. In the example according to Figure 6, a lift truck cross transport (10) takes over the bundle package at the transfer point and transports it across to a collecting station (11).

FIG. 7 shows an embodiment of the bundle former, which is inserted into the gripper tongs (6) is integrated. The belts (7) and (7a) run from the winch (13) or (13a) over the rollers (12) or (12a) in the Grippers and are respectively attached to the tip of the opposite gripper. Figure 8 shows the plan view to a complete binding line.
