Abstract

A heater heats sheets to which a powder adhesive has been applied in a binding margin. A pressing member manufactures a booklet by applying pressure to the sheets. In a first adhesion mode, an application amount of the powder adhesive applied to the binding margin is a first application amount and a heat parameter proportional to an amount of heat applied to the sheets is a first value. In a second adhesion mode, the application amount of the powder adhesive applied to the binding margin is a second application amount and the heat parameter is a second value. The first value is higher than the second value. The first application amount is lower than the second application amount.

First claim

What is claimed is:

1 . A booklet manufacturing apparatus comprising:
a heater configured to heat a plurality of sheets to which a powder adhesive has been applied in a binding margin of each of the sheets; a pressing member configured to manufacture the booklet by applying pressure to the plurality of sheets heated by the heater; and a controller configured to control the heater and the pressing member, wherein the controller has a first adhesion mode and a second adhesion mode, the first adhesion mode is a mode in which an application amount of the powder adhesive applied to the binding margin is a first application amount and a heat parameter proportional to an amount of heat applied to the plurality of sheets by the heater is a first value, the second adhesion mode is a mode in which the application amount of the powder adhesive applied to the binding margin is a second application amount and the heat parameter is a second value, the first value is higher than the second value, and the first application amount is lower than the second application amount.

2 . The booklet manufacturing apparatus according to claim 1 ,
wherein the heat parameter is a heating time for which the heater heats the plurality of sheets, the first value is a first heating time, and the second value is a second heating time, and the heater is further configured to:
heat the plurality of sheets for the first heating time in the first adhesion mode; and
heat the plurality of sheets for the second heating time in the second adhesion mode.

3 . The booklet manufacturing apparatus according to claim 2 ,
wherein the heater is further configured to:
heat the plurality of sheets at a first temperature in the first adhesion mode; and
heat the plurality of sheets at a second temperature in the second adhesion mode, and
the first temperature is lower than the second temperature.

4 . The booklet manufacturing apparatus according to claim 1 ,
wherein the heat parameter is a temperature of the heater, the first value is a first temperature, and the second value is a second temperature, and the heater is further configured to:
heat the plurality of sheets at the first temperature in the first adhesion mode; and
heat the plurality of sheets at the second temperature in the second adhesion mode.

5 . The booklet manufacturing apparatus according to claim 1 ,
wherein the pressing member is further configured to apply pressure to the plurality of sheets in parallel with the heater heating the plurality of sheets.

6 . The booklet manufacturing apparatus according to claim 5 ,
wherein a pressure applied to the plurality of sheets by the pressing member in the first adhesion mode is lower than a pressure applied to the plurality of sheets by the pressing member in the second adhesion mode.

7 . The booklet manufacturing apparatus according to claim 1 ,
wherein the booklet manufacturing apparatus is connected to an image forming apparatus that forms images on the plurality of sheets and supplies the plurality of sheets to the booklet manufacturing apparatus, the controller is further configured to:
select the first adhesion mode when a throughput, the throughput being a number of sheets on which the image forming apparatus forms an image per unit of time, is a first throughput; and
select the second adhesion mode when the throughput of the image forming apparatus is a second throughput, and
the first throughput is lower than the second throughput.

8 . The booklet manufacturing apparatus according to claim 7 ,
wherein when downtime during which the image forming apparatus cannot form an image arises in the image forming apparatus, the controller switches from the second throughput to the first throughput.

9 . The booklet manufacturing apparatus according to claim 8 ,
wherein the downtime arises in response to at least one of the following:
control related to cleaning a member involved in forming the images in the image forming apparatus;
a rise in an internal temperature of the image forming apparatus;
a number of sheets on which images are formed in succession by the image forming apparatus;
performing calibration for maintaining image formation performance of the image forming apparatus; and
sensing a remaining amount of a consumable used to form the images in the image forming apparatus.

10 . The booklet manufacturing apparatus according to claim 1 ,
wherein the booklet manufacturing apparatus is connected to an image forming apparatus that forms images on the plurality of sheets and supplies the plurality of sheets to the booklet manufacturing apparatus, the controller is further configured to:
select the first adhesion mode when an image formation interval corresponding to a distance or a time between a following end of a preceding sheet and a leading end of a subsequent sheet in the image forming apparatus is a first image formation interval; and
select the second adhesion mode when the image formation interval in the image forming apparatus is a second image formation interval, and
the first image formation interval is longer than the second image formation interval.

11 . The booklet manufacturing apparatus according to claim 10 ,
wherein an ability of the first image formation interval to suppress curling in the plurality of sheets is higher than an ability of the second image formation interval to suppressing curling in the plurality of sheets.

12 . The booklet manufacturing apparatus according to claim 1 , further comprising:
a support member configured to support sheets that are conveyed from an image forming apparatus and that constitute a booklet, wherein each time a predetermined number of sheets are conveyed onto the support member, the heater performs heating processing and the pressing member performs pressing processing, and when a condition for performing an operation that will cause downtime in which the image forming apparatus cannot form an image is satisfied, the controller performs the operation after waiting for the predetermined number of sheets to be conveyed onto the support member.

13 . The booklet manufacturing apparatus according to claim 1 , further comprising:
a support member configured to support sheets that are conveyed from an image forming apparatus and that constitute a booklet, wherein each time a predetermined number of sheets are conveyed onto the support member, the heater performs heating processing and the pressing member performs pressing processing, and when a condition for performing an operation that will cause downtime in which the image forming apparatus cannot form an image is satisfied, the controller causes the heater to perform the heating processing, causes the pressing member to perform the pressing processing, and performs the operation, before the predetermined number of sheets are conveyed onto the support member.

14 . The booklet manufacturing apparatus according to claim 1 , wherein
the controller is further configured to determine the first value in accordance with a material of the plurality of sheets.

15 . The booklet manufacturing apparatus according to claim 1 ,
wherein the controller is further configured to determine a combination of the first value and the application amount in accordance with an adhesion strength required for the booklet.

16 . A booklet manufacturing apparatus comprising:
a heater configured to heat a plurality of sheets to which a powder adhesive has been applied in a binding margin of each of the sheets; a pressing member configured to man
