Abstract

Rieši sa problém manipulácie s viacvrstvovými systémovými paletami, pričom vstupno-výstupná časť je umiestnená pod pracovnou častou zariadenia. Manipulačně zariadenie pre manipuláciu so systémovými paletami pozostávajúce z pevného vstupno-výstupného štola, vodiaceho rámu a ikrclkovane pohyblivého vozíka, v ktorom je zabudovaná zdvíhacia vidlica, vyznačujúca sa tým, že vstupno-výstupný stůl je na svojej vstupnej a výstupnej časti opatřený pevne usporiadanými strediacimi klinmi, pre předběžné vystredenie palety vytvorenej z niekolkých rovnakých vrstiev, kde každá vrstva je tvořená rámom, v ktorom je Vložka pre přesné roizloženie obrob- •kov a ktorý je na svojej hornej časti opatřený strediacimi kolíkmi pre předběžné vystredenie odobranej vrstvy v otvoroch vidlice opatrenej upínacími palcami, automaticky vysúvatelnými pri zasunutí strediacich kolíkov hornej vrstvy palety do otvorOv vidlice, pričom v hornej časti vozíka sú upevnené strediace puzdra pre přesné ustavenie zdvihinutej vrstvy palety vo vidlici voči vozíku.The problem of handling multi-layer system pallets is solved, with the input-output part being located below the working part of the device. Handling device for handling system pallets consisting of a fixed input-output gallery, a guide frame and a circularly movable carriage in which a lifting fork is built in, characterized in that the input-output table is provided with fixedly arranged centering wedges on its input and output parts for pre-centering a pallet formed from several identical layers, where each layer is formed by a frame in which there is an insert for precise arrangement of workpieces and which is provided with centering pins on its upper part for pre-centering the removed layer in the holes of a fork provided with clamping fingers, automatically extendable when the centering pins of the upper layer of the pallet are inserted into the holes of the fork, while centering sleeves are fixed in the upper part of the carriage for precise positioning of the lifted layer of the pallet in the fork relative to the carriage.

Description

231483

BACKGROUND OF THE INVENTION The present invention relates to a handling device for manipulating system pallets. In the machining of parts in an automated manufacturing system, the components are stored in system pallets from which the robot or the robot selects them, inserts them into the machine tool, and processes the inserts into the system tray, you. The present invention is such that the components in the system tray are stored either in a single layer in a plane or in two layers in a circularly spaced circumference of the system pallet which must be rotated when the components are removed.

The disadvantage of this arrangement is the high load on the pallet and the need for a large maneuvering area for handling equipment.

The disadvantages of the prior art handling devices are removed by the manipulation device for manipulating the system pallets consisting of a fixed input-output gallery, a guide frame and an angular movable carriage, in which a lifting fork is mounted, characterized in that the output-output table is at its input output parts provided with fixed centering wedges, for pre-centering a pallet formed of a plurality of multi-layered layers, wherein each layer is formed by a frame in which the insert is for precisely folding the workpieces and provided on its upper part with centering pins for pre-centering the removed layer in the opening of the fork provided with clamping with the forks, automatically retractable when inserting the centering buttons of the upper layer of the pallet into the openings of the fork, whereby centering sleeves are fixed in the upper part of the pallet, precisely positioning the raised layer of the pallet in the fork against the vehicle ku.

The application of the subject matter of the invention makes it possible to use the multi-layer system pallets, thereby substantially increasing the pallet capacity and thus the shelf warehouse, while the material flow through the device is only intermittent and unidirectional. An example of a device which is subject to protection is shown schematically in the drawing of FIG. 2 in side view.

The device consists of an inlet-outlet gallery 1 provided with centering wedges 7 which forms the inlet and outlet portions of the device. The fork 2 is provided with clamping shoes 11 and serves to remove one layer 9 of the system pallet 8 into the removal height. The carriage 3 moves the raising height layer of the picking height to the exit portion while stepping along the program on the jogging drum 4.

The layer 9 of the pallet 8 is centered with its centering pins 10 on the carriage 3 in relation to the carriage 3. The individual steps of the carriage 3 are indexed by the indexing device 5, which is located on the carriage. When all components are machined, the device will lay a layer on the output part of the device. The trolley moves along the frame 6.

The feature of your device is as follows:

The system pallet 8 is formed from a plurality of identical layers 9. Each layer 9 is formed by a frame in which the liner is, allowing accurate and optimum distribution of the workpieces. The individual pallet layers are aligned with the centering pins 10.

The system pallet 8 is placed on the input-output table 1 in the input section of the induction cart 3 (re-baseline. When placed, the pallet 8 is roughly centered on the inner-center wedges 7 with an accuracy of + 2 mm. The trolley 3 is moved in the entrance section The rod 2 is lowered above the pallet 8. It is stopped by approaching the top layer 9 (10 mm). The clamping fingers 11 and the layer 9 are clamped.

By raising to the take-off height, the pins 10 (closer to the carriage) are pushed into the two centering bushes 12 in the carriage frame 3. Thus, the position of the removed layer 9 in the carriage 3 is precisely set and started to be stepped. The individual steps of the carton 3 are indexed and centered by an indexing device 5, which displaces the indexing tip into the template of the stepping drum 4, which is fixed on the frame 6 of the device. The fork 2 places the pallet 8 in the access-exit table 1. The empty fork 2 is lifted to the take-off height The truck 3 moves without stepping into the inlet section. lifts up to take-off height and the entire cycle! repeats. Pallet drum 4 times the built-in 6 bars according to the size (spacing) of the machined parts.

The device can be used to manipulate the system pallet for chip machining of rotary components in automated manufacturing systems, and for automated assembly of components stored in system pallets.
