CS241288B1 - Feeder for feeding parts into the grinding space of a two-sided surface grinder vertical - Google Patents

Abstract

The feeder device is intended for feeding parts into the grinding chamber of a double-sided vertical surface grinder. It is equipped with a control element mechanically connected to the guide plates and bearing bodies of the upper feed roller. Furthermore, the control element is connected to an indicator of the set width of the feed zone. The device allows the adjustment of the adjustable elements of the feed zone using a single control element.

Description

Gripping device for feeding components into the grinding space of a double sided vertical surface grinder

The feeding device is designed for feeding components into the grinding space of a double-sided planar vertical grinder. It is provided with a control element mechanically connected to guide plates and bearing bodies of the upper feed roller. Furthermore, the control element is connected to a set feed bandwidth indicator. The device allows the adjustment of the adjustable feed belt elements by means of a single control element.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feed device for feeding components into the grinding space of a double sided planar vertical grinder in a continuous grinding process.

Up to now, in the case of continuous grinding on vertical double-sided grinding machines, the components are guided by a feeding device at the entrance between the grinding wheels, guiding the parts by means of a conveyor belt and two rollers forcedly rotating against each other. A guide plate is placed in front of the upper roller, followed by another guide plate that directs the entry of the components into the grinding zone. Since the different types of components have different ground widths, the guide plates and the two upper roller bearing bodies, i.e. four independent elements, need to be adjusted each time the feed device is adjusted.

Double-sided surface grinders have a very high productivity, for example 10,000 or more grinded pieces per hour, so adjustments to different ground widths are often performed several times per shift. Continuous adjustment of the four independent elements by the same value together with the adjustment of the upper grinding wheel represents a loss of time which reduces the capacity of such a productive machine as a double sided surface grinder.

The above-mentioned drawbacks are partially eliminated by the feed device according to the invention, which is based on the mechanical connection of the adjustable elements for adjusting the feed zone so that the rotation of one control element moves all the adjustable elements together. The actuating element is mechanically connected to the guide plates and the bearing bodies of the upper feed roller. Furthermore, the operating element is mechanically connected to the set width indicator.

The advantage of this arrangement is the possibility of fast and accurate adjustment of the feeding device to another dimension, that is, saving of the time loss during adjustment and thus increasing the capacity and productivity of the machine work.

An exemplary embodiment of the feeding device is shown schematically in the attached drawing.

At the inlet of the grinding zone between the upper grinding wheel χ and the lower grinding wheel 2, the components are guided by a feeding device guiding the components by means of a conveyor belt J. Downstream there is a lower roller 4 and an upper roller 4 above it. thereby pushing the fed parts through the abrasive

241 2M band. A guide plate is placed in front of the upper roller 6, followed by a guide plate X, which directs the entry of the components into the grinding zone. At the top there is an operating element 8, by turning of which all the adjustable elements are moved together. The actuating element 8 is keyed on a shaft 6 provided with worms 10, 11 engaging worm wheels 12, 13 with movement threads, displacing the movement screws 14, 15 connected to the bearing bodies 16, 17 of the upper cylinder 6. A pair of helical wheels 18 and 19 connect the shaft 6 to the height adjustment shaft 20 provided with the worms 21, 22 engaging the worm wheels 23 and 24 with the movement threads. The movement screw 25 is connected to the guide plate 6 and the movement screw 26 to the other guide plate. The shaft 6 is further provided with a worm 27 engaging a worm wheel 28 associated with a pointer 29 which shows a set width on the scale. The worms 10, 21 and 22 are provided with the possibility of pivoting against the helical wheels 18 and 19 because of the height adjustment of the individual elements when replacing the guide plates 60, 41. At the same time, the bearing bodies 16, 17 of the upper cylinder 6 and the guide plate 8, χ are precisely adjusted by the rotation of the actuating element.
