[Problems to be solved by the invention]
By the way, in the case of using a thermoplastic resin adhesive (hot melt type) that is heat-dissolved on the back surface of the sheet bundle, the adhesive solidifies at room temperature, so that a drying unit such as the apparatus disclosed in Patent Document 1 is used. Is no longer necessary. However, when the use environment of the bookbinding apparatus is high, it takes a longer time for the adhesive to solidify than the use reference temperature (usually 20 ° C.).
[0006]
For this reason, if the bookbinding device is used in an environment where the temperature is higher than the reference temperature, and the required holding time for holding the sheet bundle after applying the adhesive is the same as the required holding time at the reference temperature, the adhesive Since the solidification is not sufficient and the adhesive state on the back side of the sheet bundle is poor and the bookbinding is poor, the necessary holding time is set so as to solidify even at a temperature higher than the use reference temperature.
[0007]
For example, the time until the release of clamping is displayed on the display device after the application of the adhesive is completed (the indication “Please take out”) is the time for Tennori binding that only applies the adhesive to the back of the sheet bundle. It is 18 seconds, and in the case of wrapping (walnut) bookbinding in which the cover is bound after the adhesive is applied to the back of the sheet bundle, it is 10 seconds (including the cover pressing time: 6 seconds).
[0008]
However, when using it at the reference temperature, useless time is generated within the set required holding time, and even though the adhesive has already solidified, there is no indication to release the holding, and more paper than necessary is needed. The bookbinding work was inefficient because it was pinched.
[0009]
There are many types of hot melt type adhesives, each softening point, open type (time to solidify after application), set time (time to solidify by pressing the cover after application), Other properties are different, and the required time for holding the sheet bundle varies depending on the thickness of the sheet bundle and the amount of adhesive applied.

Further, the notification means is not limited to the liquid crystal display unit 18 and can be configured by a buzzer.
[0028]
When the movable clamp 28 is driven by the clamp driving device 37 instead of the driving by the operation knob 11, the signal output circuit 68 outputs a signal instructing the clamp driving device 37 to open the sheet bundle 6.
[0029]
The time required for clamping and the time required for pressing differ depending on the type of the adhesive 8, the thickness of the sheet bundle 6, the coating amount of the adhesive 8, and the temperature of the use environment. For this reason, the control unit 65 that constitutes the holding time control means and the pressure bonding time control means uses the data for each used adhesive inputted in advance as an index for the thickness of the sheet bundle 6, the amount of adhesive 8 applied, and the temperature of the usage environment. The time required for clamping and the time required for crimping are selected and set.
[0030]
For example, it is longer as the thickness of the sheet bundle 6 is larger, longer as the application amount of the adhesive 8 is larger, and longer as the temperature of the use environment is higher. The data necessary for selecting and setting the required clamping time and the required crimping time was obtained by experimentally determining the correlation between the sheet bundle thickness 6, the amount of adhesive 8 applied, the temperature of the usage environment, and the required clamping time. Data is stored in the control unit 65.
[0031]
The selection and setting of the required clamping time and the required crimping time using the temperature as an index may be fixedly set with the temperature detected by the temperature sensor 66 at the initial installation of the bookbinding apparatus 1 as an index, but in the present embodiment, each time when binding is performed. In addition, the time required for clamping and the time required for crimping are selected and set using the temperature detected by the temperature sensor 66 as an index.
[0032]
Hereinafter, the operation of the above-described configuration will be described. As shown in FIG. 9A, in the initial state, the coating unit 3 is in the standby position, and the adhesive reservoir 43 corresponds to the electromagnetic induction coil 48. Next, the bookbinding mode that is set to either the top binding or the case binding as a default value is switched to a desired bookbinding mode by turning on one of the selection buttons 21 and 22. The default value of the bookbinding mode is switched by operating the setting button 23.
[0033]
In this state, when receiving an ON operation of the main switch 15, the controller 65 energizes the electromagnetic induction coil 48 of the coating unit 3 prior to the bookbinding operation, causes the heating plate 50 to generate heat, and stores the adhesive in the adhesive reservoir 43. 8 is heated and melted, and the application roller 44 is rotated by the application roller rotation motor 46 to enter a standby state.
[0034]
Next, as shown in FIG. 9B, when the start button 19 is turned on, the control unit 65 drives the crimping unit driving device 52 to place the crimping unit 5 at a predetermined upper position below the clamp unit 7. The fixed plate 54 of the crimping unit 5 is disposed with a predetermined gap between the fixed clamp 27 of the clamp portion 7 and the lower end of the movable clamp 28.
[0035]
In this state, the sheet bundle 6 is inserted between both sheet bundle holding members 29 and between the fixed clamp 27 and the movable clamp 28, and one side of the sheet bundle 6 is aligned with the fixed plate 54. Next, the operation knob 11 is rotated, the rotational force of the shaft 34 is transmitted to the screw shaft 31 via the transmission belt 35, both screw shafts 31 are driven synchronously via the synchronization belt 33, and screwed into the screw shaft 31. The holding part 32 to be moved is moved. As the holding unit 32 moves, the movable clamp 28 approaches the fixed clamp 27, and the sheet bundle 6 is sandwiched between the movable clamp 28 and the fixed clamp 27.
[0036]
Next, as shown in FIG. 9C, when the start button 19 is turned on again after the holding of the sheet bundle 6 is completed, the controller 65 drives the crimping unit driving device 52 to drive the crimping unit. 5 is lowered to a lower predetermined position.
[0037]
When performing case binding, the control unit 65 places the cover 12 on the cover table 13 and waits until the start button 19 is turned on again. The gluing operation is started without receiving the ON operation of the start button 19 again.
[0038]
In the gluing operation, the control unit 65 drives the application unit driving device 42 to reciprocate the application unit 3 along the rail 39 and the rail shaft 41, and rotates the application roller 44 to remove the adhesive 8 in the adhesive reservoir 43. It is applied to the back side of the sheet bundle 6 in both the forward path and the backward path.
[0039]
At this time, the application amount of the adhesive 8 is changed according to the sheet bundle thickness detected by the sheet bundle thickness sensor 36. When the sheet bundle thickness is thick, the application roller 44 is rotated in the forward direction in the forward path and the return path in which the application unit 3 moves to increase the coating amount. When the sheet bundle thickness is thin, the application roller 44 is moved forward in the forward path. The amount of application is reduced by rotating in the direction and reversely rotating the application roller 44 in the return path.
[0040]
When performing sheet binding, the control unit 65 applies the adhesive 8 to the sheet bundle 6 with the timer circuit 67 in a state where the application unit 3 is returned to the standby position as shown in FIG. Measure the elapsed time after completion. At this time, as shown in FIG. 10C, the crimping unit 5 is retracted integrally with the cover board 13 and the movable shooter 59 until the movable shooter 59 corresponds to the shooter 17.
[0041]
The control unit 65 uses the temperature measured by the temperature sensor 66 as the temperature condition of the usage environment, and selects and sets the necessary holding time from the data stored in advance. When the detected temperature is higher than the reference temperature, the reference holding at the reference temperature is necessary. The required holding time is set longer than the time, and when the detected temperature is lower than the reference temperature, the required holding time is set shorter than the reference holding required time at the reference temperature. Further, the necessary holding time is set longer as the thickness of the sheet bundle 6 is larger, and is set longer as the application amount of the adhesive 8 is larger.
[0042]
When the elapsed time reaches the necessary holding time, the control unit 65 outputs a signal instructing display of a wording notification of bookbinding completion such as “please take out” from the signal output circuit 68 to the liquid crystal display unit 18 of the operation unit 14. . After confirming the bookbinding completion word displayed on the liquid crystal display unit 18, the operator operates the operation knob 11 to separate the movable clamp 28 from the fixed clamp 27.
[0043]
By this operation, as shown in FIG. 10C, the sheet bundle 6 with the bound cover sheet 12 falls from the clamp portion 7 and is discharged through the movable shooter 59 and the shooter 17. When the clamp driving device 37 is provided, the clamp driving device 37 receives the signal from the signal output circuit 68 and moves the movable clamp 28 to open the clamp portion 7 to discharge the bookbinding.
[0044]
In case binding, when the coating unit 3 returns to the standby position as shown in FIG. 9D, the controller 65 drives the crimping unit driving device 52 as shown in FIG. 9E. Then, the pressure bonding unit 5 is raised to a predetermined upper position, and the cover sheet 12 placed on the cover table 13 is pressed against the back surface of the sheet bundle 6 by the fixing plate 54.
[0045]
Next, as shown in (f) of FIG. 9, (a) and (b) of FIG. 7, the control unit 65 drives the movable plate driving device 57 to press the movable plate 56 toward the presser unit 55. Then, the cover sheet 12 and the sheet bundle 6 are pressure-bonded between the movable plate 56 and the pressing portion 55, and bookbinding is performed as shown in FIG.
[0046]
At this time, the pressing force of the crimping unit driving device 52 is transmitted from the movable block 63 to the fixed block 61 via the spring 64, and the pressing force of the movable plate 56 becomes equal regardless of the thickness of the sheet bundle 6.
[0047]
As shown in FIG. 10A, the control unit 65 presses the cover sheet 12 against the back surface of the sheet bundle 6 with the fixed plate 54, and presses the cover sheet 12 and the sheet bundle 6 between the movable plate 56 and the pressing unit 55. The state is continued, and the elapsed time after the application of the adhesive 8 to the sheet bundle 6 is completed by the timer circuit 67 is measured.
[0048]
The controller 65 uses the temperature measured by the temperature sensor 66 as the temperature condition of the usage environment, and selects and sets the required crimping time for maintaining the crimped state of the cover 12 after the application of the adhesive 8 is completed from the data stored in advance. To do. This time required for crimping is the time required for crimping the cover 12 in case binding, but it is set as the time including the time required for clamping. When the detected temperature is higher than the reference temperature, the time required for crimping is longer than the time required for standard crimping at the reference temperature. The time is set to be long, and when the detected temperature is lower than the reference temperature, the time required for pressure bonding is set shorter than the time required for pressure bonding at the reference temperature. The time required for crimping is set longer as the thickness of the sheet bundle 6 is larger, and is set longer as the coating amount of the adhesive 8 is larger.
[0049]
When the elapsed time reaches the time required for crimping, the controller 65 drives the movable plate driving device 57 to retract the movable plate 56 to release the crimping state as shown in FIG. The apparatus 52 is driven to lower the crimping unit 5 to a predetermined lower position integrally with the cover table 13 and the movable shooter 59. Subsequently, as shown in FIG. The movable shooter 59 is moved backward to a predetermined position integrally with the movable shooter 59 so that the movable shooter 59 corresponds to the shooter 17.
[0050]
Next, the control unit 65 outputs from the signal output circuit 68 a signal for instructing the display of the wording indicating completion of bookbinding such as “please take out” to the liquid crystal display unit 18 of the operation unit 14. After confirming the bookbinding completion word displayed on the liquid crystal display unit 18, the operator operates the operation knob 11 to separate the movable clamp 28 from the fixed clamp 27.
[0051]
By this operation, as shown in FIG. 10C, the sheet bundle 6 with the bound cover sheet 12 falls from the clamp portion 7 and is discharged through the movable shooter 59 and the shooter 17. When the clamp driving device 37 is provided, the clamp driving device 37 receives the signal from the signal output circuit 68 and moves the movable clamp 28 to open the clamp portion 7 to discharge the bookbinding.
[0052]
【The invention's effect】
