Description

2. The device according to claim 1, of which it is e with the fact that / for the purpose of multilateral. supply of products directly from the bunker, pos edny is supplied with vertical walls

Kami, dividing the bunker into channels, respectively, the creek of the tray, and the partitions and the entry parts of the streams of the tray are arranged console with a gap above the working surface of the plate.

The invention relates to the automation of technological processes, and is intended, in particular, for the group supply of products such as semiconductor devices to control automata. A vibratory loading device is known that contains a vibrator-driven flow including streams for moving products and a hopper 1. A disadvantage of the known vibrating loading device is that two moving masses, each separately, oscillate with the same amplitude along the working length of the masses, which does not allow There is no p-relocation of product flows with increasing intervals between them, which are necessary for reliable orientation of the products. The purpose of the invention is to increase the reliability of the device by ensuring the movement of the flow of products with the interval between them increasing. The goal set is achieved by that. In the vibratory loading device containing a tray, including streams for moving articles and a hopper, a window is made in the tray, in which a hopper is located associated with the tray by means of vertically placed springs additionally inserted into the device; the form of an elastic plate, located in the direction of the bottoming, of the plate products, the working surfaces of the said plate and the tray are located in the same horizontal plane .. In addition, for the purpose of multi-feed of products directly latter continuously from the hopper is provided with vertical baffles GOVERNMENTAL, section yuschimi buoy ker channelization m respectively Ruch River tray, and wherein the septum zahodnye streams tray portion arranged cantilevered with clearance above the work surface of the plate. FIG. Figure 1 shows schematically the proposed (vibratory loading device, the general view in Fig. 2 is the same, plan view; Fig. 3, section LL in Fig. 1; Fig. 4, section BB in Fig. 1; Fig. 5 product. (semiconductor device; Fig. 6 is view B in Fig. 5; the Vibrating loading device comprises a tray 1 fixed to the base 2 using inclined springs 3j and a hopper 4 embedded with a gap in the window made in lot 1, and connected with the latter by means of vertically arranged springs 5, Anchor 6 of the electro-magnetic vibrator through brackets 7 with the bracket F to tray 1, and the electromagnet 8 is fixed to base 2 via bracket 9. Each end of the ng1 inclined spring 3 is connected to tray 1 and base 2 by means of clamp 10 and rod 11, which allows the change of 1 spring 3 at angles l fl, providing thereby controlling the oscillation trajectory of the flow 1 and of the hopper 4, Tray 1, applicable for the oriented supply of semiconductor-type products (Lig. 5 and 6y has a series of streams 12 formed by right guides 13, on the cantilever; which, on the length a, are attached bosses 14 s, uyj7oo6pa3Hb iH flexible elements 15, made of spring wire and installed at a distance of about 20 cm, Bottom 13, Bottom 4 in the direction of the movement of the products is made in the form of an elastic, well-arranged plate 16 , while the working surface 17 of the plate 16 and the working surface 18 of the tray 1 are located in the same horizontal plane. In order to increase the elasticity in section 16, longitudinal grooves 19 are formed. The bunker 4 is equipped with vertical bridges 20 which divide its space into channels 21 corresponding to the number of streams on J. flow. Each channel 21 is equipped with a valve 22 and smoothly desiccated, cantilever-mounted on the bunker case with 4 tongs 23 with working surfaces 24, Partitions 20, and also the lead-in parts of the guides 13 arranged 1ad with the plate 16, mounted relative to it with the Slide grip, the Product of FIG. 5 and provided with a leg 25, located on the tray 1 in the grooves 26 (FIG. 4), a flange 27, a small flag 28, the upper part of which is located about from the lower bearing surface of the flange. The small flag is welded to the tube 29, and the large flag 30 to the tube 31. The flags are separated from each other in height by segment 2, the distance from the lower bearing surface of the flange to the middle of the segment is equal to segment e. . The vibrating-hole loading device operates as follows. Tray 1 receives excitatory oscillations from the electromagnet 8 fixed on the base 2, which feeds from an alternating current network of industrial frequency. Making oscillations with a small amplitude (0.3 mm, tray 1 through pairs of springs 5 excites KOJie6aEinH of the bunker 4, Since the mass of the bunker 4 is small and the rigidity of the pair of springs 5 is small, the bunker 4 oscillates with a large amplitude (the amplitude of the oscillations in the upper part of the section A-A is 0.6 .tM, and at the end of the plate 16 is about 1.3 M1.) The products are loaded in portions into the channels of the bunker 4 formed by partitions 20 and flaps 22. Moving down along smoothly decreasing surfaces 24 m 23, products pass through the gap, where they are separated by intense vibration , if you previously holed up in the state of mutual coupling by flags 30 and 28. Then, moving along the working surface 17 of the plate 16 under the action of the displaced center of gravity, the product with the legs 25, sink into the longitudinal grooves 19 of the plate 16 of the bunker 4, as a result, they occupy a vertical position. The small rigidity and large length of the plate 16 contribute to the fact that the products in the segment t / under the action of the ever-increasing oscillation amplitude move with increasing speed. This causes the formation of increasing gaps between the products, which is necessary for reliable and fast carrying out of their angular orientation. Pass on the increased console hour -. These plates 16 under the orienting. device on the segment Oh, each product receives an angular orientation. It consists in turning it with arcuate elastic elements installed at a height b above the working surface 17 and at a distance Γ above the top of the flags 28. It acts on an eccentric positioned relative to the vertical axis of the flange 27 of the tube 31, due to the different magnitudes of the amplitudes the product and the arcuate elastic element of the product instantly dissolve, taking up the position of the tube 31 backward relative to the direction of the twin. After the passage; a1, of the cut of the product, the flow smoothly, in the slip mode, moves into the streams of tray 1 along the guide surfaces 13. The said smooth movement prevents the flanges of the product from interlocking. At the end of tray 1, the products are transmitted by a group feeder B of the cassette (not shown. This embodiment improves the reliability of the device by ensuring the movement of products with an increase in the interval.
