Abstract

The utility model provides an anti-returning device for preventing an object entering a carrying disk from returning back. The anti-returning device comprises stop pieces, torsion springs, bases and a rotating shaft, wherein the stop pieces are fixed on the bases through the rotating shaft in a rotatable manner; when the stop pieces rotate to the vertical direction, the upper ends of the stop pieces are higher than the surface of carrying disk through through holes in the carrying disk; under a condition of no outer force, the stop pieces can automatically rotate to vertical positions under the supporting of the torsion springs; under the action of thrust and gravity of an object on the carrying disk, the stop pieces can counteract the acting force of the torsion springs and rotate to positions below the surface of the carrying disk. According to the anti-returning device, the object can successfully enter the carrying disk; when the object returns back in the direction to an inlet of the carrying disk, the stop pieces work to stop the object from dropping out of the carrying disk.

Description

A kind of anti-rollback device

Technical field

The utility model relates to field of mechanical technique, is specifically related to a kind of for the anti-rollback device on carrying disk.

Background technology

Automatic conveyor is widely used in some instrument and equipments, when article are sent to a certain position automatically, is pushed to a carrying disk, does other processing.If after article enter carrying disk, under accidental external interference, to carrying disk entrance rollback, next article can be hindered in moving process, make a mistake.

Summary of the invention

The technical problems to be solved in the utility model is: overcome in background technology, thereby the article that enter carrying disk may rollback hinder the correct mobile defect of next article.

The technical solution adopted in the utility model is:

A kind of anti-rollback device, is arranged on the arrival end of carrying disk, for preventing from entering the object rollback of carrying disk, comprises block, torsion spring, pedestal and rotating shaft;

Described block is fixed on described pedestal by rotating shaft is rotating, and in the time that described block turns to vertical direction, described block upper end by the through hole on described carrying disk above described carrying disk surface, the lower end of described block has the groove that holds described torsion spring, and the two side of described groove is applied in described rotating shaft;

Described torsion spring is positioned at described groove, torsion spring body is applied in described rotating shaft, one end of torsion spring is connected to the roof of described groove, the other end is connected on described pedestal, so that described block is not in the time being subject to External Force Acting, under the support of torsion spring, be automatically brought to vertical position, and the application force that overcomes torsion spring in the time that block is subject to the thrust of object on carrying disk and Action of Gravity Field rotates;

Described pedestal is positioned at the rear of described block, prevents that described block from rotating to the arrival end direction of described carrying disk, and described pedestal is fixed on external device, supports the other end of described torsion spring.

Further, the upper surface of described block is an inclined-plane, and described inclined-plane rises gradually along the direction that enters carrying disk.

Further, described pedestal has the fixed part that lays respectively at described block the right and left, and with the abutting part of described torsion spring butt, described fixed part is applied in described rotating shaft.

Further, the fixed part of described pedestal and described rotor axis mechanical are fixed together.

Further, in described rotating shaft, there are multiple blocking units that formed by described block, torsion spring, pedestal.

The beneficial effects of the utility model are: prevent from entering the article rollback of carrying disk, thereby do not affect the correct movement of next article.

The specific embodiment

The utility model is in prior art, and the article that pushed carrying disk by automatic transfer equipment may be at rollback under external interference, thereby disturbs the correct mobile defect of next article, and a kind of device of article from carrying disk rollback that prevent is provided.

Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, anti-rollback device of the present utility model, is arranged on the arrival end of carrying disk, for preventing from entering the object rollback of carrying disk, comprises block 1, torsion spring 2, pedestal 3 and rotating shaft 4;

Described block 1 is fixed on described pedestal 3 by rotating shaft 4 is rotating, and in the time that described block 1 turns to vertical direction, described block 1 upper end by the through hole on described carrying disk above described carrying disk surface, the lower end of described block 1 has the groove 11 that holds described torsion spring 2, and the two side of described groove 11 is applied in described rotating shaft 4;

Described torsion spring 2 is positioned at described groove 11, torsion spring 2 bodies are applied in described rotating shaft 4, one end 21 of torsion spring 2 is connected to the roof of described groove 11, the other end 22 is connected on described pedestal 3, so that described block 1 is not in the time being subject to External Force Acting, under the support of torsion spring 2, be automatically brought to vertical position, and the application force that overcomes torsion spring 2 in the time that block 1 is subject to the thrust of object on carrying disk and Action of Gravity Field rotates;

Described pedestal position 3, in the rear of described block 1, prevents that described block 1 from rotating to the arrival end direction of described carrying disk, and described pedestal 3 is fixed on external device, supports the other end 22 of described torsion spring 2.

In the time that object enters carrying disk, block 1, under the effect of object thrust and pressure, take rotating shaft 4 as axially entering the direction rotation of carrying disk, is oppressed torsion spring 2 simultaneously, and block 1 enters below carrying disk surface by the through hole on carrying disk, and object enters carrying disk smoothly.After object enters carrying disk, torsion spring 2 recovers deformation, and block 1, under torsion spring 2 supports, returns to vertical position.If object generation rollback, produces to the thrust that exits carrying disk direction block 1, because described pedestal position 3 is in the rear of described block 1, prevent that described block 1 from rotating to the arrival end direction of described carrying disk, therefore blocked by block 1 can not rollback for article.

In certain embodiments, the upper surface of block 1 is an inclined-plane, described inclined-plane rises gradually along the direction that enters carrying disk, make in the time that article enter carrying disk, the resistance that block produces article is less, and 2 of torsion springs need to produce very little deformation, just can meet block 1 and enter the needs below carrying disk surface.

In certain embodiments, pedestal 3 has the fixed part 31 that lays respectively at described block 1 the right and left, and with the abutting part 32 of described torsion spring 2 butts, described fixed part 31 is applied in described rotating shaft 4, on described fixed part 31, there is tightening screw 5, together with described pedestal 3 is mechanically anchored in described rotating shaft 4.Because block 1 is positioned at the centre of fixed part 31, and together with pedestal 3 is mechanically anchored in rotating shaft 4, make whole anti-rollback apparatus structure more firm.

In certain embodiments, have multiple blocking units that are made up of described block 1, torsion spring 2, pedestal 3, tightening screw 5 in rotating shaft 4, make anti-rollback device more firm, anti-rollback effect is better.

The anti-rollback device of one above the utility model embodiment being provided is described in detail, but the explanation of above embodiment is just understood method of the present utility model and core concept thereof for helping, and should not be construed as restriction of the present utility model.In the technical scope that those skilled in the art disclose at the utility model, the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.
