Individual object conveying device

Abstract

The invention discloses an individual article transportation device which comprises a circular cam, a rotation support, a slide arm, a slide arm base, an elastic reduction part, a fetch holding claw, a claw base and two guide wheels. The rotation support can rotate around an axis of the rotation support. The slide arm base is fixed on the rotation support. The slide arm and the slide arm base arematched with each other in a sliding way along the vertical direction of the slide arm. And the slide arm can reciprocate along the radial direction of the rotation support. A claw base shaft is arranged on the front end of the slide arm. The claw base is arranged on the front end of the slide arm by the claw base shaft and can rotate around the claw base shaft. The fetch holding claw is arrangedon the claw base. Two sections of mutually independent cam curved surface are arranged on the circular cam. The two guide wheels are respectively arranged on the two sides of the claw base. The elastic reduction part is arranged between the slide arm base and the slide arm or the claw base. Under the effect of the elastic reduction part, the two guide wheels are respectively matched with the two sections of the cam curved surface closely. When the individual article transportation device works, the rotation inertia of the claw base part is small, and the slide arm cannot jitter, so that the action of grasping articles is more accurate. The energy consumption is lowered, and the noises are small.

Description

technical field [0001] The invention relates to an individual item transport device. Background technique [0002] In the beverage or pharmaceutical filling industry, a large number of bottles are used, and during the blowing process of these bottles, individual object conveyors are used, which are used to remove the bottles and transport them to specific positions , and the structure of the existing individual material conveying device is as described in Chinese patent ZL200580007076.6: "The rotating support is driven to rotate continuously around a substantially vertical axis of rotation (A0), and has a conveying arm, the The transfer arm has a disc mounted pivotally relative to said rotating support about a pivot (18) substantially parallel to the axis of rotation (A0) of said support ... said guide groove has a concave groove; the ram is implemented as a single piece generally in the shape of a cam curve, the profile of which is complementary to the profile of the groov...

AI Technical Summary

Problems solved by technology

[0003] 1. During the working process, the disc (including the ram and the guide groove) needs to rotate around the pivot (18), and its moment of inertia is large, which will affect the movement accuracy of the gripping head, and the movement is not accurate when picking and gripping the object ;

[0004] 2. The ram protrudes longer, which is 3 to 5 times that of the driving swing arm, and the gap between the guide wheel and the cam groove on the drive swing arm will be enlarged at the front end of the ram. At the same time, after the collision between the guide wheel and the cam groove There will be rebound, which will cause the guide wheel to swing in the cam groove, which will cause the ram part to vibrate, and also reduce the accuracy of the action;

[0005] 3. Similarly, when the disk (including the ram and the guide groove) rotates around the pivot (18), the moment of inertia is large, resulting in more energy loss and mechanical loss;

[0006] 4. During the working process, since the disc (including the ram and the guide groove) needs to rotate reciprocally around the pivot (18), its motion inertia is relatively large, which also increases the noise in the working environment
