Custodial lapped stream mechanism
View Patent ↗A device is provided for transferring printed sheet material products including a gripper conveyor having a plurality of grippers for gripping a plurality of printed sheet material products, a sheet conveyor for receiving the plurality of products from the plurality of grippers in a lapped stream, and a plurality of fingers, each finger assigned to one of the plurality of grippers, each finger contacting a first side of one of the plurality of products when a second side of the plurality of products is in contact with the sheet conveyor. A method is also provided.
1. A device for transferring printed sheet material products comprising:
a gripper conveyor having a plurality of grippers for gripping a plurality of printed sheet material products;
a sheet conveyor for receiving the plurality of products from the plurality of grippers in a lapped stream; and
a plurality of fingers, each finger corresponding to one of the plurality of grippers, each finger contacting a first side of one of the plurality of products when a second side of the plurality of products is in contact with the sheet conveyor so that the product is supported against the sheet conveyor by the corresponding finger as and after the gripper releases the product to form the lapped stream on the sheet conveyor.
2. The device as recited in claim 1 further comprising a sensor for detecting a location of at least one of the plurality of products.
3. The device as recited in claim 2 further comprising a further sensor for detecting a second location of the same product.
4. The device as recited in claim 1 wherein the finger is flexible.
5. The device as recited in claim 1 wherein the finger is retractable.
6. The device as recited in claim 1 further comprising a controller for releasing the products from the gripper.
7. The device as recited in claim 6 further comprising a driving device for the fingers and wherein the controller also synchronizes velocities of the gripper conveyor, the sheet conveyor and the driving device.
8. A method for transporting printed sheet material products comprising the steps of:
gripping the products with corresponding grippers and transporting the products along a gripper conveyor;
depositing the products onto a sheet conveyor in a lapped manner as the products are released from the grippers;
applying pressure to the products with a finger as and after the products are deposited so that the products are supported against the sheet conveyor by the corresponding finger after being deposited thereon; and
transporting the products further using the sheet conveyor.
9. The method as recited in claim 8 further comprising the step of sensing a first location of selected one of the products.
10. The method as recited in claim 9 further comprising the step of sensing a second location of the selected one product.
11. The method as recited in claim 8 further comprising the step of counting the products.
12. The method as recited in claim 8 further comprising the step of determining a misfeed.
13. The method as recited in claim 8 further comprising the step of tracking the products.
14. The method as recited in claim 13 wherein the products are tracked using positional data.
15. The method as recited in claim 8 further comprising the step of processing batch or count data of the products.
16. The method as recited in claim 8 further comprising the step of transmitting outputs to devices further downstream.
