The present invention relates to a method for conveying solid, pulpy, powdery or liquid materials in a vertical, inclined or horizontal direction by moving back and forth the documents carrying these goods according to a special law of movement.

The purpose of this movement, described below, is to:

ι. the highest delivery rate with the lowest power consumption, d. H. the theoretically cheapest To achieve funding,

2. conveying the material in a closed mass while avoiding displacement the masses among themselves, d. H. exclude a separation of the mass according to grain size,

3. Avoid material effects on the conveyed goods, and thereby

4. to enable noiseless work.

In the previously known methods for conveying bulk goods in vibrating chutes, In the case of hordes and rescue systems, the documents carrying the material are moved in such a way that that they give the material an impulse which forces it to free itself from its base take off and fly up diagonally to the same to continue forward again on the Surface falling down.

Still other devices use inclines, even perpendicular to the conveying direction posed areas that propel the material forward.

In all of these devices, the material experiences shifts in position, which leads to a loss of force occur, but then also in particular easily crumbling materials such as coal, coke and many chemical products are broken up and thus devalued, and besides that Path that the material travels as a result of the constant being thrown in the air is uselessly enlarged.

All these inconveniences of the known processes can only be avoided by the fact that the material slides on its base, i.e. in closed masses without lifting pushes itself forward, which is achieved in the present process by the fact that here the movement of the material on its main part by a uniform or practical uniformly accelerated forward movement of the same supporting base BEZW. one correspondingly rapid, uniformly decelerated, i.e. rapidly beginning backward movement or by alternately applying both types of action in uninterrupted sequence, with one corresponding straightforward management of the documents is conveyed.

Since the base is guided in a straight line, the pulse division takes place only in one straight direction. Thereby material displacements of the individual parts of the Material to be conveyed avoided in itself, and as a result of the uniform accelerated forward movement respectively delayed backward movement of the substrate can be the existing constant pressure of the conveyed material on the substrate to achieve the greatest impulse

Grant fully utilized, i.e. the workload can be reduced to a minimum.

This pressure, which benefits the funding, causes the greatest possible uptake of living force in the mass of the material to be conveyed.

The new method is characterized by the fact that the material is lifted off the document should not occur.

The accompanying drawing illustrates three exemplary embodiments for the application of the proceedings in question.

In Fig. Ι the material in question is conveyed vertically.

The material passes through a funnel a onto a chute c supported by a handlebar b. The open end of this chute is articulated to a vertically guided conveyor pipe d , which is continuously moved up and down by means of the hanger rod, the crank loop f and the crank g indicated only in dotted lines.

The accelerating upward movement and the decelerating downward movement are only achieved indirectly by the drive device, namely by the lugs or raceways q that come into effect at the same time. The crank oscillation is also not the most essential requirement of this movement and it can be replaced by an ordinary crank device, by thumbs or non-circular disks.

The cross-section of the pipe itself can be thought of as being square. The vertical guidance of the delivery pipe d can take place in any desired manner, but in order to indicate these guides, the links Ar are shown in FIG.

The material is conveyed by shovels /, which are rotatably attached to the tube d at points m and carry the levers η with the rollers ο. If all the blades I assume the position shown in Fig. Ι drawn, the material to be conveyed slides from the channel c into the lowermost blade /.

This inward flow lasts until the pipe d, after it has descended into its lowest position, is lifted back into the position shown. From about this moment on, or even a little earlier, the rollers run onto the curved running surfaces q provided in the shaft and cause the blades to run ahead of the pipe to a certain extent and thereby give the material to be conveyed an even higher speed.

When the tube occupies the highest position that it can be imparted through the crank loop so the blades / the dotted position received and the rollers have reached ο q up to the highest edge of the tread.

The letter h in FIG. 2 denotes the speed diagram according to which the up and down movement of the pipe d takes place.

When the crank loop goes down, the pipe moves downwards at the speed corresponding to diagram h.

On the lowest part of the movement of the tube the speed of the blade / corresponds to that of the curve h. On the upper part of the tube movement the speed of the blade center corresponds to curve i.

On the two parts r of curves h and i there is a uniform acceleration upwards and a uniform deceleration downwards.

The material runs on the lowest shovel,

while the tube is on the second half of its downward motion, evenly and without fabric and accordingly. without loss of work.

The material to be conveyed is accelerated on all blades during the largest part of the upward movement, corresponding to the curve r (Fig. 2), uniformly accelerated. The acceleration pressure required for the promotion is - 'P

and consequently a constant size, hence the material down to the corrugation, which corresponds to the speed 3 in Fig. 2, living force is supplied in the most favorable manner.

In the meantime, the shovels carrying the conveyed material rise upwards, so that the same, sliding along the blades, as in Fig. 1 crossed with Arrows indicated, flies upwards to during movement from 3 through 4 and 5 to be caught in the gentlest possible way by the next higher shovel, and following the paddles during the uniformly decelerated backward movement with no cloth to return to the relative rest position - as shown ■.

The uppermost running surface q does not rise as much as the lower ones, with the result that the material, deviating more strongly from the uppermost shovel, flies from the vertical direction through the ejection tube 0 and arrives directly into the collecting funnel w.

The counterweight on the upper lever is used to Ausbalanciren the own weights of the tube d, and linkage, while the air brake is to serve these parts for adjustment of the mass effects.

By Fig. 3, a device is illustrated schematically in which the

The material is conveyed upwards in an inclined direction. The channel χ, which, is provided in known manner with blades \ to prevent the backward movement of the material, k of the links to which it is suspended, with a corresponding length thereof approximately rectilinearly in the conveying direction, in this case in an oblique direction , up and down.

These blades \ are not bent at the rear end perpendicular to the direction, but only so far, that this rear end is horizontal; so that this bending only intended to support the material, but not to exercise a Stofswirkung it.

The acceleration of the material takes place in accordance with FIG. 4 at the greatest Parts of the upward movement practically uniform, according to the direction of the arrow j / ·, which is parallel to the surface of the Shovel £ lies.

When the speed of the chute decreases at the end of the stroke, the material slides forwards along the shovel, and then backwards again by taking the gutter vibrates, the following blade moves into the material.

This prevents the material from lifting off the bucket; rather, it slips along the first shovel and without any fabric over to the next one.

Here, too, the material is accelerated uniformly as it moves forward the latter advanced in a closed mass; Changes in the position of the pieces of material in relation to one another, loss of work and shredding of the material carry with them are reduced to the slightest degree.

Fig. 5 is a cross section through Fig. 3 and is only intended to be an example of construction for one Appropriate suspension of the entire conveyor trough χ, avoiding pegs or bolts.

The design according to FIG. 6 is an example of horizontal conveyance. The promotion itself takes place both during the forward and reverse gear of the conveyor trough x.

The rollers j serve for the horizontal guidance of the latter. The drive of the conveyor trough χ is brought about here, for example, by elliptical wheels 8 and 18, which transmit their movement through the crank g and the rod e to the trough χ.

The pulley 9 rotates the driving wheel 8 at a uniform angular speed, so that the driven wheel 18 and accordingly also the crank g are moved in such a way that the desired type of movement occurs.

The diagram in FIG. 7, which is obtained by the drive shown in FIG. 6, corresponds practically the condition of the uniformly accelerated forward movement and correspondingly uniformly decelerated backward movement if the documents are kept in a straight line.

As already stated above, enables the uniformly accelerated forward movement and uniformly decelerated backward movement make full use of the constant Pressure of the material to be conveyed on the base to achieve the greatest pulse division in the Material in the conveying direction.

The following should be noted:

The frictional resistance of the rest to which the material is moving on the smooth Document opposed respectively. the normal pressure of the material, i.e. its own weight here a certain constant quantity, and only if the increase in speed with which the Base is moved, is not greater than this frictional resistance corresponds., Remains the material rest on the surface when the living force is absorbed.

In order to store a maximum of living force in the material, it is therefore necessary to have speed grow constantly, d. H. the movement must be uniformly accelerated.

Only in this way is the promotion possible in practice and at the same time the maximum of Achieved performance while consuming the least amount of work.

Should be in addition to the feed of the material through the forward movement of the smooth surface Relative feed can also be achieved by the backward movement, so it is necessary to to withdraw the document at first much faster, so that the material due to the inertia of the mass, it maintains its place in the room while the base is pulled away from underneath. Thereby again the maximum of the achievement with the smallest Effort achieved when the movement of the pad is a uniformly delayed one.

8 and 9 serve to explain in detail the manner in which the desired one was created Speed diagram.

FIG. 8 shows the uniform movement of the drive pulley, while FIG. 9 shows the gear. Speed diagram of the channel illustrated.

The speed in Fig. 9 increases almost uniformly accelerated, namely from α to β; from there it decreases rapidly to γ ^ , where it becomes zero, and then increases just as rapidly in the opposite direction, and finally decreases from & to a with a uniformly delayed movement to zero.

Means t the time unit, in which a point of the driving pulley covers a certain portion of the circular arc Fig. 8, and ρ the corresponding associated acceleration of the speed of the channel x, the movement of the latter be a uniformly accelerated when t in equal times the Acceleration ρ increases by the same amount. Then the paths s, calculated from the zero point of the movement, must behave like the squares of the times.

So if the drive pulley (Fig. 8) rotates with a uniform angular speed, the individual arcuate pieces are ^ ₁ t. ₂ t ₃ t _i and? _{5 covered} in the same times and the associated accelerations of the channel are the same according to FIG. 8.

According to FIGS. 8 and 9, this takes place uniformly accelerated BEZW. uniformly delayed Movement for about 75 pCt. every revolution and to approx. 70 pCt. of the stroke with almost mathematical accuracy.

The remaining part of the movement serves to reverse the direction of movement and may should not be chosen smaller if the device is to work substance-free.
