Bookbinding Control Device Adhesive Coating Timing for Jam Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bookbinding apparatuses face difficulties in operability and safety when the bookbinding process is stopped, particularly due to issues with sheet bundle handling and high-temperature adhesive coating, leading to poor jam clearance and potential safety hazards for operators.
Innovation Solution
A bookbinding apparatus with a control device that coordinates the gathering tray, sheet bundle conveying device, adhesive coating device, and cover sheet stitching device to ensure the sheet bundle is coated with adhesive before stopping, allowing for improved jam clearance and safety by preventing the bundle from disintegrating and relocating it to a safe area for handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the bookbinding process is stopped before the sheet bundle reaches the adhesive coating position, then the sheet bundle remains in a state of being grasped by grippers, but this causes poor operability during jam clearance and safety hazards for operators
Solution Approach 1:
The adhesive coating is applied to the sheet bundle before the stopping point is reached. This preliminary action ensures that the sheet bundle is secured with adhesive before being discharged to the gathering tray, preventing disintegration during subsequent handling and jam clearance operations.
2Productivity
If the bookbinding process is stopped with sheets discharged to the gathering tray in an unbundled manner, then the sheets are difficult to pick up and operability is poor, but continuing the process increases production time
Solution Approach 1:
The adhesive coating is applied in advance to the sheet bundle before it is discharged to the gathering tray. This ensures that even if the process is stopped, the sheets remain bundled together in a handleable state, maintaining both productivity and ease of operation.
3Object-affected harmful factors
If structural parts are installed to hide the high-temperature adhesive coating portion, then operator safety is improved, but the device structure becomes complicated
Solution Approach 1:
The adhesive coating process is extracted and completed before the sheet bundle enters the gathering tray area. By discharging the already-coated bundle to a separate gathering tray, the high-temperature adhesive coating portion is effectively separated from the operator's workspace, eliminating the need for additional protective structures.

AI summary
A bookbinding apparatus including: a gathering tray device that collates sheets sequentially fed thereto into a sheet bundle; a sheet bundle conveying device that conveys the sheet bundle collated by the gathering tray device to an adhesive coating position located downstream of the gathering tray device; an adhesive coating device that coats the sheet bundle located at the adhesive coating position with an adhesive; a cover sheet stitching device that stitches a cover sheet with the sheet bundle; and a control device that controls a bookbinding process executed by the sheet bundle conveying device, the adhesive coating device, and the cover sheet stitching device, wherein, upon receiving a bookbinding process stopping signal before the sheet bundle is coated with the adhesive by the adhesive coating device, the control device controls the adhesive coating device to coat the sheet bundle in process with the adhesive.
