Specific implementation mode
With reference to specific embodiment, the utility model is expanded on further.
Fig. 2 is gravity for transport system schematic provided in this embodiment, and the gravity for transport system is by frame 5, pallet
The compositions such as mechanism 6, deceleration mechanism 7, blocking mechanism 8, Pneumatic turnover mechanism 9.
5 both sides of frame are equipped with guide rail 14, and guide rail 14 uses hexagonal steel guide rail.Guide rail 14 includes being located at 5 top of frame just
Return guide rail 14-2 to transport guide rails 14-1 and positioned at the lower section of frame 5, positive transport guide rails 14-1 have a down dip along transporting direction Z-direction
Tiltedly, guide rail 14-2 is returned to tilt down along Return-ing direction R.The both ends of frame 5 are respectively piece uploading position O points (along the upper of transporting direction Z
Trip) and working position P points (along the downstream of transporting direction Z), position Q points to be flipped (along the downstream of Return-ing direction R).Positive transport guide rails
14-1 is connected by arc transition track with the both ends for returning to guide rail 14-2, and the positive transport guide rails 14- at the O points of piece uploading position
1 is equipped with Pneumatic turnover mechanism 9 with the return guide rail 14-2 joining places at Q points in position to be flipped.
Pallet body 6 is set on the guide rail 14 of frame 5, and can be slided along guide rail 14.Piece uploading position O and working position P, and wait for
Blocking mechanism 8 is respectively arranged at flip bit Q.
As shown in figure 3, pallet body 6 is mainly made of tray body 10, backing pin 11, walking roller 12, stop piece 13 etc.,
Walking roller 12 is symmetrically distributed in 10 left and right sides of tray body, per side 2；Backing pin 11 is arranged in 10 bottom of tray body
The heart；Symmetrical two stop pieces 13 are arranged in the end face in 10 direction of advance of tray body simultaneously, for the buffering between pallet
Blocking；Tray body 10 is the Lightened structure hollowed out, leaves the surplus bigger of load for relative to the common pallet not hollowed out.
As shown in figure 4, the walking roller 12 at 6 both ends of pallet body is mounted on the guide rail 14 of 5 both sides of frame.Due to guide rail
14 is are obliquely installed, and under gravity, the walking roller 12 at 6 both ends of pallet body can be in the guide rail 14 of 5 both sides of frame
Upper rolling, when pallet body 6, which has been run to, needs stop position, blocking mechanism 8 makes pallet body 6 by blocking backing pin 11
Stop；Guide rail 14 is used as Load-bearing rail, load-bearing capacity strong.
If only there are one pallet body 6 in the utility model gravity for transport system, then this pallet body works at one
Motion path and sequence of movement in cycle is as follows：The pallet bodies 6 of workpiece or tooling parts is loaded with from piece uploading position O points by this
The blocking mechanism 8 of position is let pass, since the action transport of gravity stops to working position P points and by the blocking mechanism of P points, it is artificial or
Person robot unloads workpiece or tooling parts, at this point, empty pallet body 6 is blocked the relieving of mechanism 8, due to gravity
Effect rolls, directly from working position P points by the return trajectory being at an angle of along the arc transition track of lower part position and with Horizon direction
To the Q points reached below piece uploading position O points, overturn to O points, and by the blocking of the position along circular arc OQ by Pneumatic turnover mechanism 9
Means block stops, and waits for piece uploading.
In the utility model, otherwise pallet body 6 is stopped or is worked by previous pallet body in transportational process
The blocking mechanism 8 of position or piece uploading position stops, when 6 quantity of pallet body being arranged in the utility model is enough, all pallets
Mechanism 6 will be stopped by previous pallet body 6 in a forward direction, and accumulative and travel type arranges in gravity system, be located at work
The workpiece or tooling parts made on the pallet body 6 of position P points are removed, and all pallet bodies 6 after P points are made in gravity
It transports the distance of a pallet body spacing forward under and is blocked；Meanwhile empty pallet body 6 is blocked the relieving of mechanism 8
And it is rolled to the blocking mechanism from Q points, when front pallet-free from P points along circular arc and the track angled with Horizon direction
When, blocking mechanism lets pass and is back to O points and is blocked by Pneumatic turnover mechanism, waits for piece uploading.
Therefore, this gravity system is not limited to accumulative and travel type or non-accumulative and travel type transport model.
Due to the effect of acceleration of gravity, the pallet body in the utility model during the motion can be with the increasing of time
Acceleration increases, and in order to reduce the impact of impact or pallet body 6 to blocking mechanism 8 between pallet body, this practicality is new
Deceleration mechanism 7 is arranged in type also in positive conveying track, absorbs the kinetic energy that a part of pallet body 6 is converted to by gravitional force,
Speed of the pallet body 6 in gravity system is reduced, whole system even running is made.
The above, the only preferred embodiment of the utility model, it is in any form and substantive not to the utility model
On limitation, it is noted that for those skilled in the art, in the premise for not departing from the utility model method
Under, several improvement and supplement can be also made, these are improved and supplement also should be regarded as the scope of protection of the utility model.It is all ripe
Professional and technical personnel is known, in the case where not departing from the spirit and scope of the utility model, when using disclosed above
Technology contents and the equivalent variations of a little variation, modification and evolution made, be the equivalent embodiment of the utility model；Together
When, all substantial technologicals according to the utility model to the variation, modification and evolution of any equivalent variations made by above-described embodiment,
In the range of still falling within the technical solution of the utility model.
