Abstract

Be a kind of pallet or do translation, or do rotation, the controlled conveyer chain of the action operation of throwing.It is the closed chain formula messenger chain by two identical parallel placements of geomery, again will be wherein messenger chain along two chain stripe pitch behind the perpendicular direction miles of relative movement A of direction, corresponding point pine at two chains changes riveted joint polylith pallet, and being the distance at the two ends by pallet, this riveted also carries out for the two-semiaxle of A, make pallet can realize the translation transmission, as required the indivedual respective sprockets on the conveyer chain suitably are offset again simultaneously, change its width between centers A value, make that pallet can rotate, the operation of throwing, be used for several work such as transmission, discharging.

Description

The invention belongs to the chain-type belt conveyor, to be a kind of chain turning along sprocket wheel or in the space during by any direction operation for it, the pallet (plate) of riveting on chain but is controlled to or do not have and rotate operation (being translation), but the conveyer of the running state of can doing again when needing to rotate, throw.

According to examination data at home and abroad, material object, and computer search learns that existing similar mechanism has three kinds: they all are to change riveted by many pallets and several chain pines to form, wherein a kind of is that each pallet and two chains are only changeed riveted with an axle pine, and the center of gravity of pallet is put into the rotating shaft below.Because the effect of weight, no matter chain how change of direction or zigzag operation, pallet is to hang like hanging basket is sagging eventually, and pallet just can often keep horizontality, and the porcelain base of some porcelain kilns of the visible Tangshan of this design is dried the conveyor line material object.Second kind also is with pallet and chain Cheng Songzhuan riveted with an axle.But another place at pallet, or the other end of axle is equipped with guide wheel or bent axle guide wheel, guide wheel in guide groove set on the frame (or on guide rail) rolls, and so just can control pallet with the shape of guide groove (or guide rail) and do translation or do rotation, the operation of throwing.This is with German patent DT2510522, and DT2601034 is the typical case.These two kinds design shortcomings are a lot, and the former plays pendulum by pallet, can not put material partially, again can not high-speed cruising.Latter mechanism complexity, friction drag is big, and conveyor belt design length is stoped.The third is to adopt to be fixed in two axles that pallet its spacing is A (or four semiaxis) pallet is riveting on four chains, does like common chain conveyor Jie structure She Ji And earlier

Shape arranges that two in the middle of the vertical target phase of chain is positioned at four chains make distance of translation to center position again then.This distance should equate with two distance between shafts A on the pallet, so just makes pallet still keep horizontality at the vertical target phase of chain, makes pallet energy vertical transport material.This is with U.S. Pat 4232782, and Russian Patent SU518424 is the typical case.This design can only be done Type is arranged, is used for the vertical transport material, can not do

Type arranges, more can not be by any dog-leg path layout, and also complex structure, the transmission resistance is big, and chain design length receives greatly to place restrictions on equally.

The present invention is will be with few part, and design constitutes pallet or do translation or make the transmission chain belt of rotation, the controllable state of throwing operation, and can press any direction, any dog-leg path is made layout, while reaches cheap again, can stablize light transmission various materials, the purpose of carrying out several work.

The present invention's (seeing Fig. 1, Fig. 2) is the chain-type sealing messenger chain that chain (8,9) that two sizes and layout is identical, sprocket wheel (4,7) or the like are formed, earlier by the parallel placement of a certain direction (for example directions X), so with the perpendicular other direction (for example Y direction) of above-mentioned direction, after wherein a messenger chain moves a distance A, cause respective sprockets (4, the 7) width between centers of two messenger chains also to be A(A ≠ 0 like this).Fixing their positions again, and each member of this frame (10,11) is the outside that is distributed in this two chain (8,9) with frame (10,11), or away from the many pallets (5) of riveted on chain (8,9) at running space.Pallet (5) both sides all are fixed with a semiaxis (3,6), and two axles (3,6) distance is A also.The other end of two-semiaxle (3,6) pine commentaries on classics respectively is riveting on the corresponding point of two chains (8,9).Because two chains (8,9) are synchronous in operation, so the motion between their each corresponding point is equation of equal altitude forever, therefore two semiaxis (3,6) on the pallet also become being synchronized with the movement of equation of equal altitude, do not have the translation of rotating so the operation of pallet (5) also just becomes.

If rotation in various degree (seeing Fig. 1 bottom) will take place near the relative position pallet (5) that suitably is offset indivedual 1 to 2 pair of respective sprockets (12,13) in service this sprocket wheel.When if the width between centers of certain a pair of respective sprockets (1,2) skew becomes null value individually (A=0 sees Fig. 3) then pallet can do 90 ° the action of throwing.Like this pallet realized rotation, the controllable state of throwing, can be used for operations such as automatic discharging.

As long as two-semiaxle (3,6) axle base A is suitably big, pallet (5) is in operation just very stable.If pallet (5) is arranged to horizontality, then it can be at smooth operation under the heavy duty.There is not other add-on parts except that chain (8,9), pallet (5), semiaxis (3,6), frame (10,11) because of the present invention again, so it is not only easily manufactured, running resistance is little, the transmission chain actual length can design very longly, and the service direction of messenger chain, route can make any broken line layout, will greatly enlarge field of application.These performances are that existing various translations, the controlled various belt conveyor that rotate, throw can not be compared.

Transmit chain belt and do S shape to the traffic altitude direction and arrange because of the present invention can make again, be used to transform occupation of land commonly used and be the baking production line of tens of meters flint road formula bread, baking vanish etc., can make it to shorten to 2～3 meters.So just reduce accounting for the premises area widely, can reach effect energy-conservation significantly, economical with materials again.

The present invention is used for belt conveyor, just can extensively be extended to every profession and trade by level, vertical or any direction of tilt convey materials, not only convenient, safety, stable, but also be very economical.
