Abstract
Abstract Buffer storage device for transfering textile coils from an irregularly operating coil feeding device to a uniformly advancing coil delivery device having a given coil delivery velocity includes a multiplicity of identical transport elements for at least one textile coil, respectively, the transport elements being shiftable towards one another, a conveyor section extending from the coil feeding device to the coil delivery device, the transport elements being movable on the conveyor section from the coil feeding device to the coil delivery device with varying and at least two-stage travel velocity so that the travel velocity thereof at least immediately before reaching the coil delivery device, in travel direction of the transport elements, corresponds to the given coil delivery velocity and otherwise is greater than the coil delivery velocity.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
139 words
Buffer storage device for transferring textile coils from an irregularly operating coil feeding device to a uniformly advancing coil delivery device having a given coil delivery velocity comprising a multiplicity of identical transport elements for at least one textile coil, respectively, said transport elements being shiftable towards one another, a conveyer section extending from the coil feeding device to the coil delivery device, said transport elements being movable on said conveyer section from the coil feeding device to the coil delivery device, and means for varying the velocity of travel of said transport elements along said conveyer section in at least two velocity states so that the travel velocity thereof before reaching the coil delivery device, in travel direction of the transport elements, corresponds to the given coil delivery velocity and otherwise is greater than the coil delivery velocity.
Claim 2
Dependent Claim
139 words
Buffer storage device for transferring textile coils from an irregularly operating coil feeding device to a uniformly advancing coil delivery device having a given coil delivery velocity comprising a multiplicity of identical transport elements for at least one textile coil, respectively, said transport elements being shiftable towards one another, a conveyer section extending from the coil feeding device to the coil delivery device, said transport elements being movable on said conveyer section from the coil feeding device to the coil delivery device, and means for varying the velocity of travel of said transport elements along said conveyer section in at least two velocity states so that the travel velocity thereof before reaching the coil delivery device, in travel direction of the transport elements, corresponds to the given coil delivery velocity and otherwise is greater than the coil delivery velocity.
Claim 3
Dependent Claim
52 words
Buffer storage device according to claim 1 including means for indicating the transport-element content of the storage device, and means for switching off the coil feeding device when a predetermined maximal transport-element content is reached and for switching off the coil delivery device when a predetermined minimal transport element content is reached.
Claim 4
Dependent Claim
40 words
Buffer storage device according to claim 1 including at least one endless conveyer belt is associated with said conveyer section for transporting said transport elements, said endless conveyer belt having a travel velocity greater than the given coil delivery velocity.
Claim 5
Dependent Claim
44 words
Buffer storage device acording to claim 3 comprising advancing means for stepwisely transporting an empty transport element to the coil feeding device and for simultaneously transporting farther into operating range of said conveyer belt a filled transport element located adjacent the empty transport element.
Claim 6
Dependent Claim
34 words
Buffer storage device according to claim 4 wherein said transport elements are slidably mounted on said conveyer belt during stepwise transport thereof by said advancing means, at least before reaching the coil delivery device.
Claim 7
Dependent Claim
45 words
Buffer storage device according to claim 1 including a common stepping mechanism associated with the coil delivery device and said conveyer section for stepwise advancing said transport elements with a rhythm corresponding to that with which the coils are delivered by the coil delivery device.
Claim 8
Dependent Claim
32 words
Buffer storage device according to claim 1 including means defining guidance contours for transforming individual textile coils to the coil delivery device, said guidance contour means being associated with said conveyer section.
