Description

(54) DEVICE FOR SEARCHDING DISTRIBUTION OF PARTS

 The invention relates to mechanical engineering and can be used when loading with oriented parts of machine tools and automatic lines.

It is known a device for single-piece firing of parts with different ends, comprising a drum with primary and secondary orientation slots located radially one above the other, with orientation knives l located in the secondary orientation slots.

This device allows you to reliably view parts only with a displaced center of gravity relating to the geometric center of their direct ego contour.

The aim of the invention is to improve the reliability of the device.

This goal is ensured by the fact that each nest of the primary orientation is provided with a xeno node for displacing parts relative to the orienting knife and a separating flap mounted rotatably between the nests of the primary and secondary orientation, and the node for displacing parts relative to the orienting knife is in the form of pushers on

the end of which and on the opposite wall of the nest of the primary orientation are made symmetrical to each other bevels directed toward the nest of the secondary orientation.

The invention is illustrated in the drawing, where in FIG. 1 shows a general view of the described device; Fig. 2 - the same, view from the side of the st10 of a smaller diameter; in fig. 3 is a section A-A in FIG. 2; in fig. 4, the mechanism of displacement with a child, in which the center of gravity does not coincide with the geometric centers of the Commution, oriented in the forward direction; in fig. 5 - the same, with the part oriented in the opposite direction; in fig. 6 — displacement mechanism with a part with a center of gravity

20 coincides with the geometric center of the contour oriented in the forward direction; in fig. 7 - the same, with the detail oriented in the opposite direction; in fig. 8 - 25 times cut BB in FIG. 6

Claims (2)

The device for single-piece dispensing of parts contains a pre-bunker 1 with an automatic feeding mechanism 2 with parts and a preliminary guide 30 with a conventional tray 3, a hopper 4 coupled with a rotating gripper with a orientation block, made in the form of a two-stage drum 5, along which generators are formed on large-diameter stages 6 7-8, respectively, of primary and secondary orientation, are located one under the other, and at stage 9 of smaller diameter — nest 10 for receiving oriented parts. The nests of the primary orientation are made in the form of il-l2 pockets, separated by an orienting knife 13, set in the prices Tpie of the nest of the secondary orientation. The pockets go to guide rail 14, through which the secondary orientation socket communicates with the socket for receiving oriented parts. The first drum stage 6 is in conjunction with a bunker, the second stage 9 is with an outlet tray 15. Each slot 7 of the primary orientation has a length L, is longer than the length of the part 16 (for better sink-down of parts) and is equipped with a mechanism 17 for displacing parts relative to the center of the corresponding slot of the secondary orientation of the separating rotary valve 18 with the lever 19 driven from the fixed cam 20 mounted on the second stage side. The mechanism 17 for displacing parts is made in the form of a pusher 21 positioned with the possibility of axial movement in the first stage of the drum drum 22, coaxially with the primary orientation slot and cooperating at one end through roller 23, which is common to all followers, with a sliding cam 24 mounted from the side the first stage is a block a and, and the other end, from the pa end of the pusher and on the opposite wall 25 of the nest of the primary Origentak, coaxial bevels 26-27 of length 5 are made according to the shape of the end of the part of smaller diameter P face 23 is continuously pressed against the cam 24 by a spring 28 rigidly associated with the end of the pusher bar 29. Slots for .priema oriented detaleyzakryty S- flap 30. The length of stroke: 21 tolkatol selecting a ratio of. The device allows orienting and delivering parts both with the displaced center C of the body relative to the geometric center C, their outer contour (Fig. 4 and 5), and the detail Ly, at which the specified centers coincide or are displaced slightly (Fig. 7). The device works as follows. Details from prebunker 1 under the action. The mechanism 2 feeds portions are fed into tray 3 and are pre-oriented from it — fed into the hopper 4. Rolling along the sloping wall of the bunker, the parts easily fall into the slots 7 of the primary orientation, since they are pre-oriented {3 and the length L nests selected longer than the length of the part. Lightness of zapadan helps to reduce the violation of coverage. Further, the parts are transported by rotating the drum 5 to a secondary orientation position, where they are fed by the pusher 21 along slot 7 to a flap 18 separating the slots of the primary and secondary orientation. This flap is pivoted through under the action of the lever 19. inside the pockets 11–12, as a result of which the chip goes down onto the knife 13 and under the action of its own weight G sinks into one of the pockets, obtaining a secondary orientation. This dropping is ensured by the fact that in detail the center of the CY of tin plate naturally does not coincide with the geometric center of the CJL of its outer contour. It is offset by the value of l. On the inclined guide tray 14, the part also under the action of its own weight is sent to slot 10 to receive oriented parts: where it is transported to the POSITION of slot 10 with the window of the exit tray 15. Soft cloth 30 from the inside, prevents parts from falling out of the socket.10 during transport. This is the way to dispense parts with an offset center of gravity. When working with parts whose center t rigidly coincides with the geometric center (or is slightly displaced), by means of the pusher 21, the part is set each time with an offset of ../2 in one direction or another relative to the knife 13 depending on the nature of the primary orientation. The tick, in the primary orientation in the forward direction, the part is shifted by the value of DE with respect to the knife 13 to the left, and in the case of the opposite orientation, to the right by the same amount. In this case, the center C of the body of the part shifts by the indicated amount, thus creating favorable conditions for secondary orientation. This is achieved due to coaxial bevels 26-27, where the orientable part enters with a smaller diameter end. After the part has been moved, the pusher 21 moves back before the valve 18 is opened. Claim 1: A device for single-piece dispensing parts with different ends, comprising a drum with primary sockets and secondary orientation, located in the radial direction one below the other, and orienting knives are located in the secondary orientation sockets, distinguish if, in order to increase the reliability of the device, each slot of the primary orientation is equipped with an offset unit, parts relative to the orienting knife and a separation flap installed with the possibility of rotation between the slots of the primary and secondary orientation. 2. The device according to claim 1, wherein the node of the displacement of parts is relatively oriented; its knife is made in the form of a pusher, at the end of which, opposite to the wall of the primary orientation opposite to it, the symmetrical bevels are made symmetrically to one another Stsronu nest secondary orientation.
