Abstract

The invention relates to devices for automatic counting of parts and can be used in mechanical engineering, instrument engineering and electronic industry. The invention allows to expand the field of application of the device and improve the accuracy of the account. For this purpose, the feeding tray is made multi-channel and mounted coaxially with the bin of the hopper, each feeding tray guide having a variable cross-sectional size. The parts moving in a spiral tray are separated by a cutter in one row, go into a guide, at the exit of which a separating inclined tray is installed to create the necessary for reliable counting the gaps between the parts in front of the photosensor which is installed at the beginning of the reset zone. The separation tray is made in the form of two parallel flexible plates, one end of the top plate is placed flush with the surface of the guide feed tray and rigidly attached to it, the other end is movably placed in the groove of the bracket, which has the possibility of fixed vertical movement relative to the guide feed tray , and has a bevel that smoothly passes from its working surface to the discharge of parts, at the beginning of which a photo sensor is mounted. 5 il.

The invention relates to devices for the automatic counting of parts and can be used in mechanical engineering, instrument engineering and electronic industry.

The purpose of the invention is to expand the tenological capabilities by counting parts of different sizes and improving the accuracy of the account.

FIG. 1 shows the device, a general view; in fig. 2 - view A ia of FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 is a view of B in FIG. 3 in FIG. 5 shows the node I in FIG. 3

The device for counting parts consists of a hopper 1 (Fig. 1), with a vibrodrive 2, the bowl 3 of the hopper 1 has a spiral tray 4. Coaxially with the bowl 3. the bunker 1 on its flange 5 with screws 6 is fixed a multichannel feed stock 7, containing several guides 8, each of which has a cross-sectional size different from the others. At the exit of each of the directions, LLYuDI 8, a regulating separation tray 9 is installed, consisting of two flexible elastic plates 10 and 11, one end of which is rigidly fixed in the guide 8 and the other is movably installed in the slots 12 of the bracket 13. At the same time, the upper plate 10 is an extension of the guide 8, and the bracket 13 with the base 14 is installed in the slots 15 with the possibility of a fixed vertical movement of the screw 16 to obtain the required angle of inclination of the separation tray 9, which creates certain intervals by means of exit from it, corresponding to their reliable account. To protect the screw 16 from spontaneous turning, a nut 17 is installed under the action of vibration. The end of the top plate 10 has a bevel 18 which smoothly passes from its working surface 19 to the initial relief zone 20. The bevel 18 is intended to create additional linear acceleration. details and the formation of a guaranteed gap between them.

At the beginning of the discharge zone 20, a photosensor 21 with an illuminator .22 and a tray 23 for resetting the parts into the container 24 mounted on the bracket 25 are installed.

The device works as follows.

The parts are loaded into the bowl 3 of the hopper 1, which corresponds to the size of the part. The guide 8 of the multichannel feed tray 7 is connected to the exit of the spiral tray 4. The shutter 26 sets the required clearance for the passage of the parts into the guide 8 in one row. shown) install the required number of parts, turn on the vibrodrive 2. The parts moving along the spiral tray 4 are separated by a cutter 26 in one row, falling into the guide 8, at the output of which the secondary separation is made lnym tray 9, i.e. creating the necessary, for reliable counting, the intervals between the parts in front of the photosensor 21. At the same time, the photosensor is mounted. at the beginning of the drop zone 20, it allows to produce a reliable counting of parts, not depending on their accumulation on the separation tray 9, since the bevel 18 of the top plate 10 allows to obtain additional linear acceleration to ensure separation of parts from each other, and inclined the regulating separation tray 9 prevents them from moving at the outlet of the guide 8 by a continuous flow. In addition, the photo sensor 21, installed at the beginning of the reset zone 20, produces a count of parts that do not depend on their overall dimensions, at the very beginning, at a low fall rate, thus increasing the reliability of the device.

Upon termination of the counting and the attainment of a predetermined number of parts in the container 24, the device is automatically switched off. Control is carried out on the light display of the counter (not shown).

To count the parts of another size, you need to install the multi-channel feed tray 7 on the bowl 3 with the corresponding guide 8 to the exit of the spiral tray 4, and the cutter 26 has a clearance for passage of parts in one row. To count parts with a different weight, you should also change the angle the nut at the output of the guide 8 to create the necessary gap between the parts corresponding to their reliable count.

Thus, the invention allows to significantly expand the scope
