CS243936B1 - Device for automatic cutting of blanks from semi-finished products in the form of flat prisms - Google Patents

Abstract

The device is mainly intended for cutting the same blanks from prismatic flat materials to obtain input material for serial production or for cutting samples. It consists of a two-piece base with fixed and sliding table. The cut material is clamped on the sliding table by the back pressure automatically with the determination of the clamping length. Under the sliding table there is a movement device for sliding to the sawmill and sleeping. The cut blanks are removed by the belt conveyor into the bunker. The device is equipped with an electrical system and a control panel. The cutting tool is equipped with a lifting cover.

BACKGROUND OF THE INVENTION The present invention relates to a device for automatically cutting blanks from blank blanks in flat beams.

The problem of gradual dividing, of various materials in the form of flat prisms with equal blanks becomes important in technical practice especially when introducing automated lines including robotics.

Also, in the field of testing and quality control, a number of identical patterns are required to obtain an average characterizing property characteristic. For some types of materials, we assume inhomogeneity and then search for the lowest, average and highest characterizing properties. Such materials are, for example, wood, minerals, heat-treated metals, plastics and the like.

The prior art systems for the working tool and the split material work together so that the storage and drive saw is guided on the carriage and is moved in the longitudinal direction of the material when moving to the cut, or the two saws move in a rocking direction. There is also a system in which the drive of the actuator moves along the guide in the cross-section above the material, or the saw is driven and the material moves on an arc with an adjustable radius. A known system in which the position of the saw is adjusted to the working table in a vertical direction in order to change the size of the saw above the work table.

The disadvantage of the devices used so far was that they did not allow accurate multi-cut cutting of blanks without operator supervision, created unsafe dust environments, worked as a single-purpose machine and, in manual operation, created environments with increased risk for occupational safety.

The above-mentioned drawbacks are eliminated by the device according to the invention, which consists in a two-part unfolding base provided with guide rails carrying a sliding table, wherein a non-movable table with a cut-out for receiving the conveyor is placed on the two-part base and under the stationary a drive electric motor of the piston disc is mounted on the two-part spreading support, with the support which is covered by the lifting cover, from the support for supporting the workpiece at the time of cutting and at the same time keeping the perpendiculars relative to the saw blade, with the indicator being provided with an indicator of presence the blank, from the feeder to the blank, to the cutting position, the end stop with the electro-mechanical contact, from the side and top presses to hold the blank at the time of cutting, wherein the slide table is provided with a securing mechanism for securing the position over time feed in the semi-finished product, from the geared e-electromotor and the moving screw to the sliding slide to the cut and sleep, the sliding table is provided with a closure carrier for engaging with the motion screw and also with a manual locking lever for cutting from the automatic and from the gear switch of the gear motor; cutting the blank and a control panel, as well as an electrical system, are provided on the two-part spacer.

In particular, the advantages of the arrangement of the device for automatically cutting the same cuts from a flat prism shaped blank according to the invention consist in automatically clamping the blank for cutting, automatically feeding it to the end stop, cutting the cut blank into the pickup, enabling the sawing to be removed and dust of the docentral separator and reservoir, and increases safety at work by covering the saw blade with a lifting cover actuated automatically by the movement of the slide gallery or by the foot lever.

1 is a side elevational view of an exemplary embodiment of the apparatus of the present invention; FIG. 2 is a side view of a control panel; and FIG. 3 is a plan view.

The device for automatically cutting flat blanks of flat blanks is formed by a base bunker 1 with the possibility of opening the saw blades or maintenance, and the guide rails 2 for guiding the movable sliding carriage 3 are fixed on the bunker. a drive electric motor 6 mounted by means of a tensioning device is placed under the movable base 1 under the stationary table 4, and a saw blade 8 is mounted on the two-part spreading base 1 and is supported by a lifting device. On the sliding table 3 there is placed a blanket 11 to support the workpiece at the time of cutting and to keep the semi-stock longitudinal axis in the timing and to maintain the perpendicularity of the blank relative to the saw blade surface. A blank indicator 17 is inserted in the tab 11. In contrast to the shank 11, a feeder 13 is disposed on the sliding table 3 for shifting the blank during cutting a front stop 18 with the electromechanical contact 183 to turn off the feeder 13.

Also on the sliding table 3 is a side presser 12 and a top pusher 14 for holding the workpiece at the time of cutting and providing a lock 13 for positioning the displacement gallery during the feed of the workpiece. A sliding table is a movement device consisting of a gearbox.
