,. :' ' .:
belt, ~hile a third, intermi.ttently moving conveyor belt, ;n line with .
` the second, feeds the articles to the receivin~ statio-n.
.~ Such apparatus is commonly used in si.tuations where large quantities of articles, such as chocolate bars, are delivered 013 a conveyor belt and .
; 10 are to be fed to a machine for ~urther treatment or for packaging. A ~ ~.
.~; problem generally encountered here is, that the receivi.ng machines are :
capable of accepting articles only with a certain frequency, ~hereas .~ :
~`.......... articles are delivered by the conveyor belt in quantities and at intervals ~i ;3 of time which are not synchronized w1th this frequency.
~;. ~3e conveyor belt which delivers the articles usually moves at a -uniform speed.
A known solution to the~above proble~ where, for example~ articles ~
delivered by a~con~eyor belt are fed to a packaging machine to one side o~ the belt, is the following. At the end of a first con-reyor belt7 at ;20 rieht angles to it and in comm3~3ication with it~ is a second conveyor beJ.t. ~ ;
.. ~ ., .
Thie Decond belt, while~stationary, receives the articles from the ~irst belt for example, by their sliding from one to the other - after which :
the oecond belt 6tarts to move at-"..niform speed and transports the articlei3 in the dire.^itio2. of the receiving machine. The articles are then : :~
transferre.d from the ~ec.ond bélt to a third belt, which travels inter-mitter3tly touards the machine and coms3~3icates direotly with ita intake, the frequency of movement of thi~ third belt ceir,g 6ynchronized with the fregueir.cy with which the machine c~ accept the article6~
~ ",, ' ' . . , An appropriate means, such as a photoelectric cell, can be used to indicate when the second belt is empty of articles.
If this is the case, the uniform movement of the belt is caused to cease and it is then ready to receive the next batch of articles.
This known sclution has a number of disadvantages, the most important of which is that machine capacity, i.e. the quantity of articles that can be handled per unit of time, -cannot normally be fully utilized.
This follows from the circumstance that, once the load on the second belt has been transferred to the intermittently -moving feeder belt for the machine, the uniform movement of the second belt is arrested so that it is ready to receive the next load. In this interval - while the arrival of the next load is ::,- :
awaited and during the loading process - no transfer of artlcles to the third belt takes place. This means that, between the last :, ~
article of a given load and the first article of a following load, ~ -there is an empty space on the third belt, which results in the machine receiving no articles during the passage of this empty space past the machine.
~,.1 ~ . . . .
The apparatus according to the invention avoids the above-mentioned disadvantage in that a fourth conveyor belt is dis-posed between the second and third conveyor belts, this fourth .. . .
;"! belt being coupled to and synchronized with the second belt when the latter is in motion, and being coupled to the intermittently moving t~ird belt when the second belt is at a standstill.

The presence of the fourth conveyor belt makes it possible to utilize the handling capacity of the machine optimally, in !,; that a sufficient number of articles is made available at the ` intake side of the machine.

36~33 the feeder belt for the machine - is continually recharged. In this case, no empty space occurs on ~he third belt and the machine is fed withou-t interruption in the supply of articles. Once the next load has been deposited on the second belt, the latter starts to move at uniform speed and, with it, the fourth belt in synchronization. In this n~anner, the first article of the new load is placed on the fourth be~t up against the last article of the previous load. Once the second belt is clear of articles, the uniform movement of both the second and fourth belts is ', ~ . .
arrested, the fourth belt starts to move intermittently, and so on. In these circu~stances, no empty space ever occurs on the intermittently - moYing feeder belt for the machine. Care must~ of course, be taken to ~` ensure that the rate of supply of art}cles to the fourth belt is such ~., ; .
~ that it is not allowed to become empt~, ~
,~.. .:. ~, , .
The desired coupling between the second and fourth belts, and ~ between the fourth and third belts, respectively, is preferably achieved 5 - ~ ~ with the aid of free-wheel transmission assemblies. When the second belt :. . ::: -stops, the coupling between the second and fourth belts is then automatically "free" aDd the fourth belt is then entrained by the thlrd belt by way of their mutual coupline.

In order to ensure that the articles on the intermittently moving eeder belt are properly closed up, it is advantageous for the intermittent travel, i.é. the distance covered per movement, of the fourth belt to be somewhat greater than that of the third belt.

, The invention is detailed below in conjunction with the drawing, in wh;ch 1 represents a conveyor belt on which articles are delivered at uniform speed in the direction 2. This conve~-or belt 1 cooperates with a second, transversely disposed conveyor belt ~ ~hich t-ravels in the direction 3, the delivered articles being "deposited" on this second belt by their being pushed onto it while the belt is stationary. Arrange-ments may be made for the momentum of the articles to cause them to strike the stop 5, which may be useful with a view to their correct orientation. After the load has been thus transferred, conveyor belt 1 ;;- 10 adopts the position corresponding to 1a, so that following articles C2~t :` ' .
; be transported on a secondary conveyor belt 6, possibly to another transverse belt operating in the same manner as tranverse belt 4.
The second conveyor belt 4 now stsrts to move at uniform speed `~'! ' in the direction 3, the articles being transported to the conveyor belt 7, correspondlng to the "fourth conveyor belt" referred to above. This belt -~
7 is coupled to the belt 4 by means of the schematically represented~ i tran=mîssion assembly 8 and also moves at the same uniform speed in the ,!, :
direction 9. The articles are thus transferred to the belt~7. When the photoelectric cell 10 no longer detects any articles on the belt 4, the i 4 ?Q-: latter ceases its uniform movementJand the conveyor belt 1 resumes its rai=ed~position in order that another load of article= may be deposited on the belt 4. The belt 7 ceases its uni~orm movement simultaneousl~
with belt 4, the transmission assembly 8 switches to the ~ree-wheeling position and the belt 7 then begins to move intermittently in the direction 9. This intermittent movement is imparted tv the belt 7 by way of a transmission~assembly 11 from the intermittently moving belt 12, which latter com~unicates with thé receiver, e.g. a packaging machine.
During the period in which the belt 7 moves at unifolrm speed, i,e, is coupled to the belt 4, the transmis~ion assembly 11 acts as a free-:,~ : . .
