【Example】

 An embodiment of a cartridge attaching / detaching mechanism according to the present invention will be described below with reference to the drawings. 1 and 2 are perspective views of a bookbinding apparatus 10 to which the cartridge attaching / detaching mechanism of the present invention is applied, as seen from different directions. Since the bookbinding apparatus 10 is a preferred specific example to which the cartridge attachment / detachment mechanism of the present invention is applied, the bookbinding apparatus 10 will be described first.

The carriage 100 reciprocates between a first position P1 and a second position P2. The first position P1 refers to the home position. The second position P2 is a position at the limit of reciprocal movement of the carriage 100. Further, at the second position P2, the backing tape 12 is exchanged for each cartridge. 1 and 2 show a state in which the carriage 100 is moved to the second position P2 in order to show the structure in detail. The bookbinding device 10 also includes a large number of sensors S1 to S7 and a control unit 14. The control unit 14 controls operation commands of various processes by signals from the sensors S1 to S7.

In order to facilitate understanding, first, a process until the bookbinding work is completed will be briefly described. As shown in FIG. 1, the laminated paper 16 is pushed on the mounting table 28. The laminated paper 16 comes into contact with the raised stopper lever 30 as shown by the phantom line in FIG. The pressing arms 34 and 36 facing each other vertically sandwich and hold the laminated paper 16 and detect its thickness. The carriage 100 at the first position (home position) P1 sends out the backing tape 12 while moving toward the second position P2. The back adhesive tape 12 is attached to the back surface 18 of the laminated paper 16 and the temporary fixing rods 40 and 42. The press rollers 60, 62, 64, 66 which are vertically separated from each other rotate to press the surplus portion of the backing tape 12 protruding vertically from the back surface 18 of the laminated paper 16 against the front surface and the back surface of the laminated paper 16. The press rollers 60, 62, 64, 66 are rotationally driven to move the laminated paper 16 forward. The backing tape 12 is firmly pressed against the front and back surfaces of the laminated paper 16. Then, the press rollers 60, 62, 64, 66 are reversed, and the backing tape 12 is again pressed against the laminated paper 16 by the press rollers 60, 62, 64, 66. The laminated paper 16 for which the bookbinding operation has been completed is discharged onto the mounting table 28. The carriage 100 returns to the first position (home position) P1.

Next, the structure of the bookbinding apparatus 10 will be described while following the above process. First, as shown in FIGS. 1 and 2, the bookbinding device 10 is disposed on a base 20, and on the base 20, side frames 22 and 24 are erected so as to face each other. The side frames 22 and 24 have means for holding the laminated paper 16, means for pinching the backing tape 12 on the front surface and the back surface of the laminated paper 16 (these means will be described in detail below). Installed. A pair of rails 26 for the carriage 100 are laid on the base 20. The carriage 100 reciprocates along a rail 26 between a first position P1 and a second position P2.

The sensor S1 (see FIG. 2) confirms that the carriage 100 is in the first position (home position) P1. The signal from the sensor S1 is sent to the control unit 14. The control unit 14 confirms that the carriage 100 is at the first position P 1 and raises the stopper lever 30 as shown in FIG. The clamp arms 34 and 36 are located at positions that are opened vertically. The horizontal rods 50, 52, 54 and 56 for supporting the press rollers 60, 62, 64 and 66 are also in a vertically expanded position. When the above conditions are satisfied, the laminated paper 16 is ready to be received.

It is confirmed that the laminated paper 16 is correctly aligned at the left end and the front end of the mounting table 28. As shown in FIG. 2, the laminated paper 16 is aligned with a plurality of stopper levers 30 rotatably attached to the base 20 with the inside of one side frame 22 as a reference. Then, the sensor S3 attached to one side frame 22 (see FIG. 1) and the sensor S4 (see FIG. 2) including a photo coupler provided at the tip of the stopper lever 30 and below the mounting table 28 are laminated. The exact position of the paper 16 is detected. The light emitter at the tip of the stopper lever 30 projects light obliquely toward the light receiver below the mounting table 28. The sensor S4 confirms that the back surface 18 of the laminated paper 16 is in contact with the stopper lever 30 at a plurality of parallel positions.

When the laminated paper 16 is pushed along the one side frame 22 on the mounting table 28 and brought into contact with the stopper lever 30, one side of the laminated paper 16 contacts the side frame 22 of the sensor S3. The sensor S4 detects that the other side of the laminated paper 16 is in contact with the stopper lever 30. The sensors S3 and S4 send a signal to the control unit 14 that the laminated paper 16 is in the proper position.

A means for temporarily holding the laminated paper 16 is required in order to prevent the laminated paper 16 from falling on the mounting table 28. Therefore, as shown in FIGS. 1 and 2, a plurality of upper clamping arms 34 and a plurality of lower clamping arms 36 are provided. The upper clamping arm 34 is pivotally supported by a support rod 32 that is vertically movably fitted into the elongated holes of the side frames 22 and 24. The lower clamping arm 36 is fixed to the lower surface of the mounting table 28. When it is confirmed that the laminated paper 16 is aligned in the regular position, the control unit 14 activates the driving means (not shown) to rotate the link 38 (see FIG. 2). The support rod 32 moves downward, and the pressing arms 34 and 36 sandwich the laminated paper 16 from above and below.

As shown in FIG. 2, a sensor S5 is provided on the other side frame 24. The sensor S5 detects the vertical position of the support rod 32 and sends the thickness of the laminated paper 16 on the mounting table 28 to the control unit 14 as an electric signal.

Next, the carriage 100 moves, and the back adhesive tape 12 is attached to the back surface 18 of the laminated paper 16. The carriage 100 is shown in detail in FIGS. The back adhesive tape 12 is stored in the cartridge 102, and the replacement of the back adhesive tape 12 is performed in cartridge units.

The carriage 100 reciprocates between a pair of rails 26 of the base 20 between a first position P1 and a second position P2. A rack (not shown) is attached between the rails 26, 26. As shown in FIG. 5, the carriage 100 has a motor 108 and a pinion 106 driven by the motor 108 via the worm gear 104 on the lower surface. As a result, the carriage 100 reciprocates. The rotation of the motor 108 is detected by the rotary encoder, and the signal is sent to the control unit 14.

The carriage 100 has a cartridge base 101. The cartridge base 101 can move in the same direction as the carriage 100. On the upper surface of the cartridge base 101, a pair of vertical shafts 114 and 116 that rotate by rotating gears 110 and 112 are provided. The cartridge 102 is fitted on the basis of these vertical shafts 114 and 116. The carrier of the backing tape of the cartridge 102 engages with the vertical shafts 114 and 116. The gears 110 and 112 are rotationally driven by the rotation of the cartridge motor, and the backing tape 12 is sent out from the cartridge 102.

To facilitate replacement of the cartridge 101, the carriage 100 has a cartridge attachment / detachment mechanism. 6 to 9 show this cartridge attaching / detaching mechanism. The cartridge base 101 has elongated holes 131, 132, 133, and 134 at the four corners. Four studs 141, 142, 143, 144 provided on the carriage 100 are fitted in the long holes 131, 132, 133, 134. As a result, the cartridge base 101 can move in one direction with respect to the carriage 100.

Other studs 150, 151 are provided on the carriage 100 and the cartridge base 101. Reference numeral 152 denotes a link, which is fitted into the stud 151 of the carriage 100 at one end and the stud 151 of the cartridge base 101 in the central long hole 153. A torsion coil spring 154 is interposed between the other end of the link 152 and the cartridge base 101. The studs 150, 151, the link 152, and the torsion coil spring 154 constitute a link means 130 for holding the cartridge base 101 at either the forward limit position or the backward limit position.

As shown in FIG. 4, the cartridge 102 is mounted on the cartridge base 101. 8 and 9 show the inside of the cartridge 102 mounted on the carriage 100. A feed roller 124 is provided upright on the carriage 100, and is rotationally driven by a motor (not shown). The cartridge 102 has a pinch roller 156 facing the feed roller 124. The backing tape 12 is sent to the outside of the cartridge 102 via a pinch roller 156. The backsheet 13 of the back-adhesive tape 12 is suspended by a winding roller 159 through a pinch roller 156, a partition wall 158.

FIG. 8 shows the case where the cartridge 102 is at the forward limit position. The vertical shafts 112 and 114 and the feed roller 123 are driven, and the backing tape 12 is fed from the cartridge 102. FIG. 9 shows the case where the cartridge 102 is at the backward limit position, and the cartridge 102 is attached and detached.

As shown in FIGS. 1 and 3, the carriage 100 further includes a pressing roller 120 that presses the back adhesive tape 12 fed from the cartridge 102 toward the back surface 18 of the laminated paper 16. Further, the carriage 100 has a cutter 122 between the cartridge 102 and the pressing roller 120. The pressing roller 120 is actuated by a solenoid, and when the carriage 100 is at the first position P1, it moves back and forth toward the laminated paper 16. Further, the cutter 122 is also operated by a solenoid to cut the back adhesive tape 12 sent from the cartridge 102 into an appropriate length. S6 is a sensor for detecting the length of the back surface 18 of the laminated paper 16 on the mounting table 28 when the carriage 100 moves from the first position P1 to the second position P2.

As shown in FIG. 2, the side frames 22 and 24 are provided with a pair of temporary fixing rods 40 and 42 which are vertically separated from each other. The temporary holding rods 40 and 42 are rotatably supported by the side frames 22 and 24. After the laminated paper 16 is sandwiched by the clamping arms 34 and 36, the back adhesive tape 12 sent out from the cartridge 102 has its end portion moved forward and backward by the pressing roller 120 provided on the carriage 100. It is crimped to the temporary fixing rods 40 and 42. Then, the carriage 100 moves from the first position P1 toward the second position P2. The control unit 14 controls the moving speed of the carriage 100 and the feeding speed of the backing tape 12. As the carriage 100 moves, the back adhesive tape 12 is attached to the back surface 18 of the laminated paper 16 and the upper and lower temporary holding rods 40 and 42. The backing tape 12 is prevented from loosening. The pressing roller 120 presses the back surface of the backing tape 12 toward the laminated paper 16. At the same time, the sensor S6 detects the length of the back surface 18 of the laminated paper 16 and sends the signal to the control unit 14. The stopper lever 30 is pressed by the carriage 100 and is in the laid-down posture as shown by the solid line in FIG.

When the control unit 14 confirms the length of the back surface 18 of the laminated paper 16 by the sensor S6, the motor 108 of the carriage 100 is stopped and the cutter 122 is operated. As a result, the back adhesive tape 12 is attached to the back surface 18 of the laminated paper 16 with an appropriate length. The control unit 14 restarts the carriage 100. The sensor S2 provided at the second position P2 detects the arrival of the carriage 100, and the control unit 14 stops the carriage 100. FIG. 6 shows the back adhesive tape 12 adhered to the back surface 18 of the laminated paper 16 and the temporary fixing rods 40 and 42 in this way.

Next, the back adhesive tape 12 attached to the back surface 18 of the laminated paper 16 is also attached to the front surface and the back surface of the laminated paper 16. The mechanism for this is shown in FIGS. 1, 2, 11 and 12. Reference numerals 70 and 72 are upper swing arms, and 74 and 76 are lower swing arms. The respective pivot arms 70, 72, 74, 76 rotate about support shafts 80, 82, 84, 86. The upper swivel arms 70 and 72 have a first horizontal rod 50 and a second horizontal rod 52, and the lower swivel arms 74 and 76 have a first horizontal rod 54 and a second horizontal rod 56. The first horizontal rods 50 and 54 respectively include a plurality of pressing rollers 60 and 64 that are spaced apart at equal intervals. The second horizontal rods 52, 56 have cylindrical second pressing rollers 62, 66, respectively. A drive mechanism (not shown) is provided below one of the side frames 22, and four lateral rods 50, 52, 54, 56 are interlocked and rotated by a belt and a gear.

As shown in FIG. 11, the support shafts 80, 82 of the upper swing arms 70, 72 are pivotally supported on the respective ends of the six links 91, 92, 93, 94, 95, 96. There is. Further, the support shaft 80 of the upper turning arm 70 is attached to the support shaft correction mechanism 88. The control unit 14 receives the signal of the sensor S5 which detects the vertical position of the support rod 32 of the upper clamping arm 34, and corrects the vertical position of the support shaft 80 of the upper turning arms 70 and 72. As a result, the upper turning rod 70 turns according to the thickness of the laminated paper 16.

The revolving arms 70, 72, 74, 76 are actuated by a drive mechanism (not shown) provided below the other side frame 24. In FIG. 11, as the central horizontal link 92 moves forward, the turning arms 70, 72, 74, 76 are rotated from the solid line position to the chain line position so as to narrow the facing interval. When the control unit 14 confirms that the carriage 100 is at the second position by the sensor S2, it activates the support shaft correction mechanism 88, and then activates the drive mechanism of the presser rollers 60, 62, 64, 66 to rotate. The arms 70, 72, 74, 76 are rotated.

FIGS. 13 to 15 show a process in which the press rollers 60, 62, 64, 66 pinch the backing tape 12. First, as shown in FIG. 13, the back adhesive tape 12 is adhered to the back surface 18 of the laminated paper 16 and the temporary fixing rods 40 and 42. The revolving rod rotates, and the pressing rollers 60 and 64 contact the back surface of the back-pasting tape 12 between the laminated paper 16 and the temporary fixing rods 40 and 42. As shown in FIG. 14, the laminated paper 16 is introduced between the pressing rollers 60 and 64. The pressing rollers 60 and 64 move the laminated paper 16 forward, and simultaneously bend the surplus portions of the laminated paper 16 projecting up and down on the front surface and the back surface of the laminated paper 16. The vertical distance between the press rollers 60, 62, 64, 66 is kept slightly smaller than the thickness of the laminated paper 16 by the sensor S 5, and the press rollers 60, 64 press the backing tape 12 therebetween. Further, the second pressing rollers 62, 66 press the entire surface of the backing tape 12 from the back surface.

S7 (see FIGS. 1, 14 and 15) is a sensor that detects that the laminated paper 16 has advanced a certain amount. This sensor S7 informs the control unit 14 that it is at the forward limit position of the laminated paper 16. The control unit 14 outputs an inversion signal to the drive mechanism of the presser rollers 60, 62, 64, 66. As shown in FIG. 15, the laminated paper 16 is vertically pressed again by the first pressing rollers 60 and 64 and the second pressing rollers 62 and 66 when retracted. When the drive mechanism rotates a certain amount, the control unit 14 stops the drive mechanism. The laminated paper 16 to which the back adhesive tape 12 is attached on the back surface, the front surface, and the back surface is discharged onto the mounting table 28.

Next, the control unit 14 sends an activation signal to the motor 108 of the carriage 100 to return the carriage 100 from the second position P2 to the first position P1. Further, the control unit 14 raises the stopper lever 30 and returns the lateral rods 50, 52, 54, 56 to the expanded posture. The bookbinding device 10 is in a standby state for the next bookbinding work.

When the back adhesive tape 12 is removed, the carriage is moved to the second position, and the cartridge is replaced at that position. When the cartridge is moved with respect to the carriage, the feed roller of the carriage and the pinch roller of the cartridge are separated from each other. After that, the cartridge is pulled out upward. Then, when a new cartridge is inserted into the vertical shaft and the cartridge is moved in the direction of the feed roller, the spine tape is sandwiched between the feed roller and the pinch roller, and the replacement is completed.

[Effect of the device]

 In the present invention, since the feed roller that is driven to rotate is provided on the side of the carriage that is the fixed member and the pinch roller is provided on the cartridge, the backing tape can be sent out based on the feed roller on the side of the fixed member. The backing tape can be delivered accurately. In addition, since the drive means, for example, the path for transmitting the rotational drive force from the motor to the feed roller is simplified and there is no need to use gears or belts as in the conventional case, the amount of rotation of the drive means is accurate. Can be transferred to the backing tape. Since the pinch roller is provided in the cartridge, there is no need to perform the work of feeding the backing tape between the feeding roller and the pinch roller, and it is easy to mount the cartridge in the carriage and move it. By the work, the backing tape can be sandwiched between the feed roller and the pinch roller, which has the effect of greatly simplifying the replacement work.
