Abstract
Abstract In a process for delivering cylindrical containers into machines for further processing, the containers slide into a feed channel under gravity in a random sequence and are transported through this channel in an upright position by the action of an intermittently operating thrust. From the feed channel, the containers are transferred in sequence to a transport carriage equipped with individual holders which are successively positioned in relation to the feed channel. When fully loaded, the transport carriage is driven into the machine for further processing.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
253 words
An apparatus for delivering objects, having a circular cross section, in an upright position to machines for further processing comprising: a horizontal feed channel; a horizontally downwardly inclined feed shaft on which the objects slide randomly in an upright position into the feed channel under the force of gravity; sliding means disposed at one end of the feed channel for imparting an intermittent thrust to the objects in the feed channel to transport the objects side by side and in an upright position through the feed channel; transport carriage means having individual holders for the objects to hold them in an upright position for transferring a set of objects from the feed channel to a station for further processing, the transport carriage means comprising a rake having individual holder slots arranged in a straight line, each configured to hold one object and means for displacing the rake parallel to said straight line; means for sensing the transfer of each object from the feed channel to the rake and for generating a sensing signal when each individual one of the objects is transferred; and control means receptive of the sensing signal for asynchronously coordinating the movements of the sliding means and of the transport carriage means to effect displacement of the rake after the transfer of one object and to disable actuation of the sliding means until the rake has been positioned correctly in relation to the feed channel such that an empty holder slot is aligned with the outlet of the feed channel.

Claim 3
Dependent Claim
42 words
An apparatus as claimed in claim 1, wherein the sensing means comprises a recoiling locking pawl and a switch coactive therewith for producing the sensing signal when an object passes the outlet end of the feed channel and actuates the locking pawl.
Claim 4
Dependent Claim
18 words
An apparatus as claimed in claim 1, wherein the individual holders have clamping springs for retaining the objects.
Claim 5
Dependent Claim
34 words
An apparatus as claimed in claim 1, wherein the sliding means comprises means for returning same and reactuating same when an object has not been pushed into the individual holder within a predetermined time.
Claim 6
Dependent Claim
40 words
An apparatus as claimed in claim 1, wherein the sliding means comprises an adjustable slip clutch for driving same and which comes into operation when the force expended to push the container in the feed channel exceeds a predetermined value.
Claim 7
Dependent Claim
30 words
An apparatus as claimed in claim 1, wherein the sliding means comprises a cog which loosens the containers in the storage shaft during its return movement into its starting position.
Claim 8
Dependent Claim
24 words
An apparatus as claimed in claim 1, wherein the rake is adapted to be deflected about an axis parallel to the direction of transport.
Claim 9
Dependent Claim
43 words
An apparatus as claimed in claim 4, further comprising means for driving the rake for the movement of translation and an electric displacement pick-up coupled therewith and whose output voltage is compared with given nominal values for the exact positioning of the rake.
Claim 10
Dependent Claim
63 words
An apparatus as claimed in claim 1, further comprising a guide tube connected at one end to the rake and mounted at its other end in a bearing so as to be rotatable about its longitudinal axis but not displaceable in the axial direction, and a displacement guide for effecting the bearing to be displaceable in the longitudinal direction for movements of translation.
Claim 11
Dependent Claim
52 words
An apparatus as claimed in claim 9, further comprising a ball bearing arrangement screwed to the outside of the guide tube and an axial guide rod which is square in cross-section and which is rotatable about its longitudinal axis and wherein the ball bearing arrangement rolls on the four lateral surfaces thereof.
Claim 12
Dependent Claim
52 words
An apparatus as claimed in claim 8, wherein the control circuit for operating the sliding means and for operating the rake comprises a step-by-step switching mechanism which, in response to the signal released by the locking pawl in its closing movement, successively dictates the rated voltage values for positioning the transport rake.
Claim 13
Dependent Claim
87 words
An apparatus as claimed in claim 11, further comprising a proximity feeler in communication with the locking pawl and which gives off a signal when the locking pawl is closed again after transfer of an object to the rake, effecting the step-by-step switching mechanism to switch forwards by one step so that the next holder is positioned in front of the feed channel, and wherein immediately after this position has been reached, the control circuit sets the sliding means in motion for transfer of the next container.
Claim 14
Dependent Claim
73 words
An apparatus as claimed in claim 12, further comprising a time switch in communication with the control circuit and which checks whether the transfer of an object to the rake is reported back by the proximity feeler within a given time and which, in the absence of such a report, sets the automatic repeating device in operation so that the sliding means is returned to its starting position and again put into operation.
