Description

The present invention relates to a chain conveyor and more particularly to a conveyor which permits an accumulation of a certain number of trucks on a section of the conveyor in accordance with the unloading procedure.
- It is known to employ chain conveyors for displacing, over a certain horizontal distance, trucks carrying a load, the return of the empty truck to the point of departure occuring below the forward travel. It is then necessary to add to the conveyor proper means for lowering the trucks at one end and raising the trucks at the other end, and this requires distinct driving mechanisms provided with considerable control means which affect the cost price and the reliability.
An object of the invention is to considerably simplify these mechanisms by providing a device which effects both the horizontal transfers and the raising and lowering of the trucks by a single driving means.
According to the present invention there is provided a chain conveyor comprising a frame, supporting two endless parallel driving chains movably mounted on said frame, trucks drivingly engaged by said two chains, a driving sprocket wheel and a return sprocket wheel for each of said two chains, the respective sprocket wheel and the respective return sprocket wheel being contained in a corresponding vertical plane, said driving sprockets engaging said two chains and being so arranged that said two chains are driven by said driving sprockets in a forward direction in an upper path and in a return direction in a lower path below said upper path, said trucks being unloaded at an end of said upper path and being returned empty in said lower path, each truck comprising at least one axle, two sprocket pinions each engaging with a respective one of said two chains and a friction coupling device mounting said pinions on said axle, said conveyor further comprising .~ ~

10Further features and advantages of the invention will be apparent from the following description with reference to the accompanying drawings, which illus~rate an embodiment given by way of a non-limiting example.
In the drawings:
15Fig. 1 is a side elevational view of an embodiment of the conveyor according to the invention;
Fig. 2 is a partial plan view of the conveyor of Fig.
1 ;
Fig. 3 is an end elevational view of the conveyor in 20the direction of arrow F of Fig. 1;
1239~1~
Fig. 4 is an ~arged cross-section view along line rv-rv of Fig.l.
Fig. 5 is a side elev~tional Yiew of one of the ends of the conveyor.
The conveyor shown in the drawings comprises a frame 1 provided with legs lc bearing on the ground. A motor 2 drives, through a transmission 3, a transverse~shaft 4 on which are keyed two driving sprocket wheels 5 located at one end of the frame 1. Extending around each of these wheels 5 is a double chain 6 consisting of two rows (6a,6b) of links which engage, at the other end of the frame 1, a return sprocket wheel 7. The engagement is achieved by the row 6b of links adjacent to the interior of the frame 1, which 1s formed by longitudinal girders la, lb (inter-connected by cross-members 23 and vertical posts 24).
Disposed above and below the frame 1 are two side members 8a, 8b each having a vertical flange 9 and a hori-zontal branch 10 fixed to the cross-members 23 by bolts 22. Fixed to the horizontal branch 10 of the upper side member 8b is a slideway 11 along which the u~per portion of the corresponding chain 6 slides. Fixed to the horizon-tal branch 10 of the lower side member 8a is a slideway 12 in which slides the row 6b of links of the chain 6 which engages with the sprocket wheels 5 and 7.
L-section members 13 are fixed to the flanges 9 and constitute the runways for rollers 14 freely rotatively mounted on the axles 15 of trucks 15 adapted to shift the loads and dis2osed between the flanges 5.

~2~9tj~C~
Mounted on at least one or the axles 15 of each truck 16 are two sprocket pinions 17 which permanently engage with the r~w 6a of links of the chains 6 located on the outside. Each sprocket pinlon 17 is connected to the axle by a driving device which provides a friction coupling 18, known Der se assuring the release of the sprocket pi-nion 17 relative to the axle 15 beyond a certain torque.
The upper side member 8b and lower side member 8a are interconnected at each end of the frame 1 by a u-section member 19 which is bent in a semi-circumference. The outer branch 20 of the section carries, on its inner side, a fixed chain 21 of the same modulus as the chains 6 and constituting a curved rack with which the sprocket pinion 17 carried by the axles 15 engage.
Each fixed chain 21 has a development of at least substantially a semi-circumference but may optionally be extended by a rectilinear portion. Thus, in the illustra-ted embodiment, the chain 21 located adjacent to the driv-ing sprocket wheel 5 and corresponding to the lowering of the t~ucks, extends from the point A to the point B which terminates a lower horizontal rectilinear portion~ while the chain 21 located at the other end and corresponding to the raising of the truc~s extends from the point C to the point ~ which terminates the curved portion in the region of the upper side members 8b.
The conveyor just described operates in the following manner :
lZ39G~
In the hori20ntal parts not associated with a fixed chain portion 21, i.e~ from 3 to A for the upper part and from B to C for the lower part, the sprocket pinions 17 remain rigid with their axle 15 so long as no obstacle opposes the travel of the trucks 16. The latter are the-refore driven by the chain 6 which is shifted by the sprocket wheel 5 and the motor 2 at the s eed of the chain 6. When a truck 16 encounters the preceding truck or a movable abutment (not shown), a torque is created between the sprocket pinions 17 and the axle 15 causes a release of the d r i v e therebetween and therefore the stoppage of the associated truck 16, while the chains 6 continue to rotate. Thus, it is possible to accumulate as desired the full trucks 16 before the unloading station and the empty trucks before the raising thereof to the loading station. As soon as the obstacle has disappeared, the truck starts to move again.
The movable abutments and their actuating means are well known per se and therefore not described since they are not part of the invention.
When the teeth of the sprocket pinions 17 of a truck 16 start to engage, at A, with the fixed chains 21, a tor-que is created between the sprocket pinion 17 and the axle 15 causing the release of the drive therebetween. There is then produced an epicyclic movement of the sprocket pinion 17 achieving a positive driving of the trucks 16 with an over-turning thereof. This manner of travelling continues 123g6~L~
until the sprocket pinions 17 are disengaged from the chains 21 at s.
A similar operation occurs at the end of the conveyor between the points C and D achieving the raising and the over-turning of the trucks 16 which are again ready to receive a load.
It can be seen that the described device thus ~ermits achieving very simply all of the horizontal, raising and - lowering transfers with a single continuously rotating driving motor.
