The level of technology

1. The technical field to which the invention relates.

The present invention relates to the treatment of long products rolling mill, in particular, it relates to the wrapping of such products.

2. Description of the prior art,

Used herein, the term "long products" includes the rental of square section, the band-pass rolling, angle rolling, channel, beams and other similar products that are typically grouped together in the form of stacked layers of packages.

In a typical system piping long products served at the receiving station. The transport system then transports these products in the transverse direction in the stacker. During the transverse movement of the product is divided into layers.

Stacker during operation passes these layers separately on a tray, where these layers are stacked, forming a package. The package then bind or wrap.

To transfer each layer on a tray stacker typically require an average of approximately 12 seconds. This transfer cycle is significantly longer than the time required for the transport system for feeding successive layers of articles in the stacker. Thus, the stacker is a bottleneck, limiting the speed with which the system of the garter can generate packets.

The present invention is SN the terms of the effects of this bottleneck and, thus, increasing the overall performance of the piping system.

The invention

In accordance with the present invention between the receiving station and the stacker is pre-stacker. Pre-stacker constructed and installed so that it works in cooperation with the transport system for the pre-laying multiple layers of products in subpacket. Subpacket served in the stacker, which transfers these subpacket on the tray. Due to delivery of multiple layers of products on the tray during each cycle of the transfer efficiency of the stacker increases significantly with a corresponding increase in the rate of formation of packages.

Brief description of drawings

The invention will be described in more detail below with reference to the accompanying drawings, on which:

on figa-1F is a schematic representation of the system piping in accordance with the present invention during tying of the rolled strip;

on figa-2I shows a similar species, representing the tying angular rental;

figure 3 shows a graph comparing the efficiency of the piping system in accordance with the present invention with a typical efficiency of conventional systems.

Detailed description of the invention

Consider first figa which shows a stacking system in accordance with h is a worthwhile invention, which contains table 10 rolling mill designed to supply long products longitudinally in the receiving station 12. The tray 14 is set to a distance in the transverse direction from the receiving station 12. The tray is made and installed in a known manner to receive and accumulate layers of products in the form of a package.

Stacker 16 and next to him the pre-stacker 18 is mounted in front of the tray 14 and the receiving station 12. The transport system 20 operates so that it conveys the product in the transverse direction from the receiving station 12 in the pre-stacker 18.

The transport system 20 includes a transfer car 22 with a lifting platform having a vertically adjustable levers 24, the gaps between the rolls table 10 mill.

As shown in figa, the levers 24 are located under long products (in this case a strip rolled) on the table of a rolling mill. On FIGU levers are raised in order to raise the product over the table rolling mill. On figs transfer trolley was moved in the transverse direction for installation of raised arms between the chain buffer chain conveyor 26. On fig.1D levers have been omitted to supply products on the buffer chain conveyor.

The buffer chain conveyor during operation moves several layers of products on the chain conveyor 28 selek is ora, on which the individual layers of products, consisting of pre-selected quantity of the products isolated from the other products by installing swivel lifting plate 30 acting in conjunction with the lugs 32. The individual layers of products then transferred via a chain conveyor 34 submission on the advanced stacker 18.

Pre-stacker comprises a base 36, which can be adjusted vertically along, and with the possibility of rotation around the y-axis can be rotated around the X-axis, which is perpendicular to the y axis.

The upper and lower fingers 38A, 38b are transferred through the base 36. These fingers can be adjusted vertically relatively to each other and together.

Stacker 16 contains the levers 40, which can be adjusted in the cycle of migration between the receiving position as shown in figa, and a feeding position, as shown in fig.1F.

The cycle of pre-laying of the rolled strip begins, as shown in figa, with the first layer of products, rolling conveyor 34 to a position above the upper fingers 38A. Then, as shown in figv, the base 36 is lifted to raise the fingers 38A and the first layer of products on the conveyor 34 and the conveyor then moves the second layer of articles in position between the upper and lower fingers 38A, 38b. Then, as shown in figs, top pall is s 38A is turned by 90 around the Y-axis, resulting in a first layer of products placed on located below the second layer of products, forming, thus, subpacket 42.

As shown in fig.1D, the base 36 is then lowered, and the fingers 38A, 38b are reinstalled in position ready to start the next cycle of pre-laying. Simultaneously, subpacket 42 to move on the conveyor 34 in a position in which it is located above the levers 40 styling. As shown in figa, levers styling then work toward fulfilling the cycle of migration, in which they raise (arrow 44), move (arrow 46) and lowered (arrow 48) to the feeding position slightly above or the base of the tray 14, or the upper layer of the previously laid subpacket (dotted lines on file). Levers stacker then turn 90 around their axes, before they will be removed (arrow 50 on fig.1F)in order, therefore, to remove layers of subpacket 42 with respect to the vertical arm of the tray, resulting in subpacket is installed in the tray.

Levers styling then return to the receiving position in which they are ready to take the next subpacket.

As you can see in file and 1F, the transfer cycle of the stacker 16 is superimposed on the cycle of pre-laying pre-stacker 18. In other words, when the stacker 16 performs the transfer process one subpacket 42 in the tray 14 pre-stacker 18 performs a process of pre-placing additional layers of products in the following subpacket.

As each subpacket placed in the tray 14, the tray sequentially lowered (arrow 54 on fig.1F cannot be assembled a complete package. This package is then tied or wrapped with another known device (not shown) and removed.

On figa-2H illustrates the wrapping angle of the car. The operations performed by the transfer carriage 22 and other components of the transport system 20, are essentially the same as described with regard to the binding strip steel. However, the operation performed preliminary stacker 18, is slightly different when laying the corner of the car. More specifically, as shown in figa, the first layer of the four products corner of the car initially tolerated by the conveyor 34 in a position in which they are placed on top of the fingers 38A pre-stacker and adjacent to the base 36. On FIGU base 36 has been omitted for the liberation of passage for transfer of the first layer of products to position retention relative to the stop 56. Simultaneously, the second layer of the products of the three products angular rent move in the direction of the pre-stacker.

On figs base 36 is returned to the upper position, and a second layer corner of the car was passed between the fingers 38A, 38b.

On fig.2D lower fingers 38b raised so that p is DNAT second layer of products on the conveyor 34, resulting in the second layer of products is captured between the fingers 38A, 38b. As shown in figa, fingers 38A, 38b with a second layer of goods, captured between them, rotate around X-axis in the position shown in fig.2F, turning, thus, the second layer of products.

Then, as shown in fig.2G, the upper fingers 38A is turned by 90 around the Y-axis for filing an internal second layer of products on the first layer of products, forming as a result, subpacket 58, in which an inverted angular car of the second layer is installed in a corner car first layer.

As shown in fign, the upper and lower fingers 38A, 38b then re-installed in their receiving position and the base 36 is lowered. Simultaneously, the stop 56 is lowered and subpacket 58 is moved by conveyor 34 to a position above the levers 40 stacker.

As shown in Fig, stacker then performs the transfer cycle, as described above, for filing with subpacket in the tray 14. When this happens, the pre-stacker again performs the process of forming the next subpacket, which will be ready for transfer to the levers 40 stacker, when they will return to their receiving position.

As shown in figure 3, using the example of forming a package containing ten layers of products for ordinary piping system that transports one layer per cycle stacker, potrebbe the camping time t 1styling package. In contrast, the system in accordance with the present invention, in which the pre-laying two layers in subpacket, completes the package for significantly less time t2, i.e. approximately half the time required for conventional systems.

It was stated above that the present invention significantly increases the overall efficiency of the system piping, as much better use of the advantage of the loop transfer stacker.

It is also important to note that the strapping system in accordance with the present invention manipulates stacked products without the use of magnets. The system thus allows processing of non-magnetic items, i.e. bars, stainless steel, etc. and Packed in bundles of magnetic products have no residual magnetization.
