CS263397B1 - Device for handling of dimensional boxes in packaging - Google Patents

Abstract

The device enables the supply of boxes along roller conveyors and the subsequent removal of boxes into the strapping device. The device consists of a driven roller conveyor and a system of lifting mechanisms extending between its rollers, consisting of an even number of jacks fixed with their guides to the lower part of the frame on which they are fixed, by means of crossbars and forks with pivoted roller eyes, the piston rods of which are rotatably mounted in carriages, while the lower parts of the carriages are fitted with rotatably mounted pairs of guide rollers on both sides and the upper parts of the carriages extend above the level of the rollers of the driven roller conveyor after their lift.

Description

263397 2

The present invention relates to a device for handling large-sized cabinets.

Until now, the exclusive use of manual work tools is used for the packaging of sheet steel switchgear because the range of switchgear steel enclosures is diverse, with light weight ranging from 30 to 90 kg, depending on the size and charge of the electric elements. The packaging and fixing of the packaging is necessary to raise and reverse the switchboard several times, often causing mechanical damage, at least to the damage of surface coatings. The handling is physically significant and is also a source of work injuries.

The device according to the invention overcomes the above mentioned drawbacks. It consists of a driven roller conveyor and between its rollers engaging the lifting elements. BACKGROUND OF THE INVENTION The invention is characterized in that the lifting element assembly consists of an even number of jacks mounted on the bottom of the frame on which they are fastened by means of crossbars swinging the bearing rings of the cylinders whose piston rods are rotatably mounted in the carriages; fitted with rotatably mounted pairs of guide rollers and the upper parts of the carriages extend beyond the rollers of the driven roller conveyor after their lift.

The main advantages of the device according to the invention are that the large-sized cabinets can be pushed into the device from different distances along roller tracks with rubberized rollers, while physically strenuous lifting and turning work is avoided in a separate package. This handling also removes the possibility of mechanical damage to the housing or surface coatings. A further advantage of the device according to the invention is that the packaged large-sized cabinets can be moved from the device on the rubberized rollers and moved into the strapping device without the use of physically stressed work. The features of the device also make it possible to increase safety and health at work and significantly improve packaging and handling performance.

1 is a schematic front view of a device according to the present invention in a position prior to insertion of the front casings, and FIG. 2 shows a front elevational view of the casing prior to wrapping.

The device for handling large-sized boxes in packaging consists of a driven-roller conveyor and between its rollers engaging the lifting mechanisms. The lifting mechanism system consists of an even number of jacks 2 fixed by its guides 2 to the lower frame 2 on which they are fastened by the crossbars 5 and 5 of the rocker 6 of the rollers 2. the parts of the carriages 2 are mounted on both sides with rotatably mounted pairs of guide rails 10. The upper parts of the carriages 9 extend after their stroke above the level of the rollers 11 of the driven roller conveyor. The operator of the device gives a pulse for feeding the large-size housing 12 from the unmarked storage roller spindle to the rubberized rollers 11 of the driven roller conveyor.

During this infeed, all the jacks 2 of the jacks 2 are pushed below the level of the rubberized rollers 11i. The feed pulse component also gives the operator a pulse to the logic circuit to which the large-sized housing 12 is received. the center of the device according to the present invention, and in the automatic cycle, also raising the housing 12 above the level of the rubberized rollers 11 as shown in FIG. 1. In this position, the operator slides onto the housing 12 and, after this operation, impulses the device according to which the designated carriages 9 slide below the level bar 11 and, in the automatic cycle, the designated carriages 2 are raised above the level of the rollers 11. Thereby, the housing 122 is lifted by the wrapped portions as shown in FIG. 2. In this position, the operator wraps the middle portion of the housing 12 and fixes the packages 14 on the housing 12 with short adhesive tapes. they are inserted, whereby the housing 12 is lowered onto the rubberized rollers 11, which is pushed into the strapping device which is not the subject of the present invention. The packaging cycle with the other housing 12 can be repeated. During the lifting and retracting, the carriages 10 are guided in the guides 2 fixedly fixed to the frame 2 by means of guide rollers 10 • The carriages 9 are secured by rollers through the pistons 2 · The rollers 2 are swinging Stowed in forks 5, clamped to the lugs 4,
