Description

(5) LEAFLET

one

The invention relates to metal processing and can be used when stacking sheets on a pallet in a container.

This is a sheet stacker containing a feed conveyor, adjustable side guides and a front stop, and supporting nozzles 1.

Such a sheet paver does not take into account the peculiarities of the stacked sheets — their dimensions, longitudinal flexibility, and no connection between the centering elements and nozzles; therefore, it is not reliable enough in operation.

The aim of the invention is to improve the reliability of laying sheets.

The goal is achieved by the fact that, in the sheet paver containing the feeding conveyor, adjustable lateral guides and front stop and supporting nozzles, vertical grooves are made in the lateral guides, in which supporting nozzles are installed, the grooves with nozzles are located along the descending line, equidistant line the natural deflection of the sheet having the lowest stiffness, in increments decreasing in the course of feeding the sheet, and the supporting nozzles have the means to adjust their position.

The paver consists of a feed roller conveyor 1, lateral guides 2 with a lateral movement mechanism 3 and a lifting drive k, an end stop 5 with 5 water 6 longitudinal movements, a rear wall 7 installed under the conveyor 1.

Claims (2)

The guides 2 in the grooves 8 are arranged with supporting nozzles 9 for supplying compressed air, which are connected to the compressed air system, with the help of hoses 10. The pallet 11 is mounted on a sliding carriage or conveyor belt (not shown in the figures for mechanized cleaning of the foot and rapid replacement of the pallet. Moreover, the grooves 8 with nozzles 9 are located along the descending line, equidistantly, the natural deflection of the sheet having the lowest rigidity, in increments decreasing along the sheet feeding direction. In addition, the nozzles 9 have means for adjusting The proposed sheet-laying machine works as follows: using mechanism 3 and drive 6, adjust the sheet-laying machine to a given width and length of the sheet. The position of wall 7 is not adjustable, it keeps the sheet from moving backward when laying. 8, based on the minimum; the strength of the sheets processed on this unit. After adjusting the sheet-laying machine to the specified size of the sheets, the compressed air is fed through the nozzles 9. The front end of the sheet supplied by the rollers is a conveyor The tera 1 is centered by the guides 2 and supported by the weight of an air cushion created by compressed air jets emanating from these nozzles until it approaches the stop 5. When the front end of the sheet reaches this stop, its rear end leaves the conveyor rollers 1 and shutting off the air streams in succession smoothly descending into the foot; at the same time, air slowly leaves the sheet. At the beginning, the back end of the sheet is placed in the stack, since, due to the uneven pitch between the nozzles 9 along the sheet, the excess pressure in the air cushion is less. After the set of sheets of the conveyor 1 is set in the stack, the conveyor rollers 1 are stopped, the guides 2 are set to the upper position for the foot to pass when it is extended, the foot is extended by placing a new pallet instead, after which the process is repeated. The use of the proposed sheet paver reliably protects the surface of the sheets from damage during installation, while at the same time ensuring that the sheets are laid flat in the stack or container. Each sheet paver releases four people on the sheet packaging line, and using it on the packaging lines of annealed sheets of aluminum alloys, especially prone to surface damage when stacked, will reduce rejects by 0.5-1%. Claim 1. A sheet paver containing a feed conveyor, adjustable side guides and a front stop, and supporting nozzles, characterized in that, in order to improve the reliability of laying the sheets in the side guides, vertical slots are filled in which the supporting nozzles are installed, while the grooves with nozzles are arranged along the descending line, equidistant line of the natural deflection of the sheet having the smallest; stiffness, in increments that decrease as the sheet feeds. 2. The sheet stacker of claim 1, wherein the supporting nozzles have means for adjusting them. Sources of information taken into account in the examination 1. UK patent N 1262895 cl. In 8 / R, 1972.
