CS239677B1 - Modular transport section of intermediate conveyor - Google Patents

Abstract

The modular transport section of the inter-operation conveyor consists of a lower and upper track with rollers, between which a continuous groove of guide sheets is placed. The transport section is equipped with retractable stops and pallet position sensors with adjustable sliding prisms. The upper track can be double with modified translators. This solution achieves a significant increase in machine performance.

Description

The invention relates to a modular conveying section of an in-process conveyor for conveying blanks between machine tools.

The development of engineering production is characterized by an increase in the productivity of labor and the overall efficiency of production. Particularly in the case of high series components, it is advantageous to process them in automated manufacturing systems.

For example, for shaft components, which make up a large proportion of all manufactured parts in mechanical engineering, the current state of production is characterized by low levels of automation and mechanization, hence a significant proportion of human labor. Produced conveyors of similar character do not have double drift or pallet reloaders. They are intended mainly for assembly and storage for parts weighing approx. 50 kg.

These disadvantages are overcome by the modular conveyor section of the intermediate conveyor, consisting of the lower and upper tracks provided with the rollers according to the invention. Their essence is that the lower track is provided with short shafts with freely rotatable and axially secured pulleys housed in the lower frame and the upper frame, that the upper track is also provided with pulleys on short shafts, provided on the uprights, with a continuous groove between the pulleys of guide rails.

On each short shaft there is a drive chain which engages the chain pressed by the bars. At both ends of the lower frame there is a tension and drive shaft provided with a tension and transmission chain. Pull-out stops and pallet position sensors with adjustable sliding prisms are located on the upper frame. The upper track can be executed in duplicate with four pulleys on each long shaft, with translators mounted on the upper frame of the double track.

The progress achieved by the invention consists in solving the modular transport sections necessary for the assembly of automated production systems, which increase the utilization of machine output to 70 to 80%, improve working conditions and increase occupational safety and hygiene.

The invention is illustrated in the accompanying drawing, in which Fig. 1 is a schematic cross-sectional view of the conveyor section, Fig. 2 is a schematic cross-sectional view of the conveyor section, and Fig. 3 is a schematic cross-sectional view of the conveyor section.

The conveyor section of my lower track 19 (FIG. 3) is formed by a lower frame J (FIG. 1) with bearing bodies 6 (FIG. 2) in which the short shafts 2 (FIG. 3) are housed by stacks 2 (FIG. 2) and the drive chains 10 (FIG. 3). Between the rollers 2 (FIG. 2) is a groove of guide rails 2 (FIG. 3).

An upper track 17 (FIG. 3) is positioned above the lower track 49, which is formed by an upper frame 2 fixed to the lower frame X (FIG. 1 by means of six props). which is the same as the lower track 19.

On the upper frame 2 there are displaceable hydraulically operated stops 22 (FIG. 1) and pallet position sensors 21 with adjustable slide prisms 22i in which the shaft parts 6 are inserted. On the shafts 2 (Fig. 3), the rollers 2 (Fig. 2) are slidably mounted in the porous bushes. The drive of the short shafts 2 (FIG. 3) is effected by an endless chain 11 (FIG. 1) engaging tangentially from above into the drive chains 12 (FIG. 3).

The chain 11i (FIG. 1) is pressed into engagement with the strips 12 (FIG. 2) and is guided from the drive chains 12 (FIG. 3) of the upper track H (FIG. 3) through the tension chains 14 (FIG. 2) on the tensioners. and drive shafts 13 (FIG. 2) for the drive chains 12 (FIG. 3) of the lower track 19 (FIG. 3).

The tension and drive shafts 12 (FIG. 2) are self-supporting of the frame 1 (FIG. 1) and still have the transmission chains 15 (FIG. 2) mounted at both ends of the lower for driving adjacent sections.

In the double section, there is a double upper track 17 in the upper frame 2 (FIG. 3), which consists of bearing bodies 6 (FIG. 2), in which long shafts 2 with four rollers J and drive chains 10 (FIG. 3) are mounted. Hydraulic toploaders 18 (FIG. 2) of the pallets 22 (FIG. 1) are also provided in the upper frames.

The shaft parts to be machined are inserted into prisms 23 of the pallets 22 moving along the upper path 17 to the individual machines, where they are stopped by retractable stops 26. The rollers J are slidably mounted on the shafts 8 to stop the pallets when the drive is permanently switched on.

In places where the same operation is carried out on several machines, double transport sections are installed. The untreated workpieces on the pallets 22 are fed to these machines on one path and the workpieces on the pallets 22 are moved along the second parallel path to which the pallet is transferred by the translator 16. The lower track 19 is used to return the empty pallets 22 to the beginning of the conveyor.
