[Detailed description of the invention] This invention relates to a device for fixing and releasing a presser plate and for sizing a binding tube in an automatic document binding machine, and can be used only for punching work that does not involve binding documents. In addition, by simplifying the sizing device for the binding tube compared to conventional products, reducing the number of parts, and simplifying the manufacturing process, we aim to provide a product with low cost and superior operability. be.

To describe an embodiment with reference to the drawings, a pair of guide shafts 2,
A motor base 4 of a drilling motor 3 is installed vertically on the upper part of the shaft, and a protruding part 5 is provided on one side of the rear part of the motor base 2 to make contact with an operating rod of a limit switch, which will be described later. A rack 6 is fixed to the part in the longitudinal direction. 7 is a holding plate, which is attached to the lower part of the guide shaft so as to be able to rise and fall;
The lifting and lowering of the drilling motor is followed through springs 8 and 9 wound around the shaft. Note that 10 is a hollow drill of a drilling motor. In order to raise and lower the drilling motor and holding plate constructed as described above, an upper motor 11 is attached to a mounting plate 12, and a pinion 14 is fixed to the motor shaft 13 and meshed with the rack 6 to rotate or reversely rotate the upper motor. This is something to do. Reference numeral 15 is an upper limit switch which is attached to the mounting plate 16 so that it can come into contact with the protrusion 5 provided on the drilling motor base, and when the motor starts to descend and the contact between the two leaves, that is, the switch is turned off and the drilling motor is activated. Set up to rotate. As a mechanism for fixing and releasing the presser plate 7, a fourth
As shown in FIG. 6, a stop bar 17 is provided to protrude downward from the lower surface of one side of the plate, and a stop plate 19 is provided at the upper end of a support plate 18 erected on one side of the upper surface plate of the machine casing 1.
One end of the stop plate is pivoted 20, and the other end of the stop plate has a pin 21 that passes through the top plate of the machine casing 1 and is slidable up and down.
The stop bar 17 provided on the presser plate 7 is inserted into the insertion hole 22 provided in the center of the stop plate, and the spring 23 is wound around the outer circumference of the pin 21, and its elasticity causes the stop plate 19 to move upward. Press to. Therefore, as shown in FIG. 5, the stop bar is forcefully locked on one side of the upper hole wall of the insertion hole 22 and the other side of the lower hole wall, and the presser plate 7 is fixed, stopping its movement and moving backward. Proceed to the drilling process. When only drilling holes without binding documents, it is necessary to release the presser plate, and for this purpose a release rod 25 connected to a release button 24 is provided at the upper part of the stop plate 19.
is provided in the longitudinal direction, and when the lever is switched to manual mode and pushed down by hand, the stop plate 19 resists the elasticity of the spring 23 and becomes horizontal as shown in FIG. Therefore, the hole wall of the insertion hole 22 and the stop bar 17 are disengaged from each other in parallel, so that the presser plate 7 is raised by the elastic force of the spring 9. When binding documents, the pin 21 automatically lowers after the work is completed, and the engagement between the stop plate 19 and the stop bar 17 is released, and the presser plate 7 rises in the same manner as described above, and the stop plate also has the elasticity of the spring 23. The device is designed to return to normal.

Next, as a sizing mechanism for the binding tube, as shown in FIG.
6, one end of the wire 27 is attached to the metal fitting, and the other end of the wire is attached to the upper end of the sliding rod 29 which is held by the holding part 28 provided on the other side of the top plate of the machine casing 1 so as to be slidable up and down. A binding tube 30 is connected to the lower end of the sliding rod.
A push-up plate 31 is attached, and the lower end of the binding tube to be sent out is received by the plate. Therefore, when the presser plate descends, the pusher plate also rises at the same time. At this time, the descending distance X of the L-shaped fitting 26 is equal to the ascending distance X of the push-up plate 31. Therefore, the dimensions of the binding tube are determined by setting the position B of the push-up plate 31 to be at Y + 1.1 cm, which is the thickness Y of the document 32 plus 1.1 cm, from the cut surface A of the binding tube 30. . As shown in FIGS. 1 to 3, the binding tube 30 inserted into the guide tube 33 receives a signal to the binding tube feeding motor 35 when the tip of the drilling drill 10 comes into contact with the rubber plate fitted into the upper surface of the bottom plate 34. The binding tube feed roller 36 fixed to the motor shaft rotates to the left, and the lower end of the binding tube reaches the push-up plate 31 by the actuator roller 38 of the lower limit switch 37, the feed roller 38, and the feed roller 36. However, the advance of the binding tube is stopped at this plate, and the drilling motor 3 is raised.
The feeding is continued until the upper limit switch 15 is turned on, but the binding tube and the feed roller are kept in a slip state, and the device is designed so that the binding tube of the required size can be cut by the cutting device.

Various processes such as perforating the document, cutting the binding tube, and caulking the binding tube are performed by known methods, and will be briefly explained with reference to the drawings as follows.

When a document is placed on the top plate and the upper motor 11 is rotated to the left, the pinion 14 fixed to the shaft engages with the rack 6 attached to the drilling motor 3, and the drilling motor begins to descend. Limit switch 15 that was in contact with protrusion 5
The operating rod is separated and the drilling motor 3 starts rotating.
After that, the motor continues to descend, but the presser plate 7
It also follows this and descends. Presser plate 7 reaches the document
As described above, the stop bar 17 provided on the plate stops the advance at the stop plate 19 provided on one side of the top plate of the machine casing, but the drilling motor 3 continues to descend and drill holes in the document, and the tip of the drill 10 is the bottom plate 34
When the drill reaches the rubber plate provided in the upper motor 11, a reversal signal is sent to the upper motor 11, and the drilling motor moves upward. On the other hand, as described above, the binding tube 30 is sent out to an appropriate size onto the push-up plate 31 by the feed roller 36 and the actuator roller 38 of the limit switch. A pin 40 provided at the lower end of the binding tube cutting shaft 39 whose upper end is fixed to the drilling motor base 4 and moves up and down together with the base pushes up the claw 41 engaged with the pin 40 when the cutting shaft rises. , as shown in FIG.
The lever 42 integrally formed with the lever 42 swings back and forth about the pivot 51 as a fulcrum. Therefore, when the tube cutting shaft 39 rises, the rear end of the claw 41 that engages with the pin 40 rises, and the upper end of the lever moves forward (towards the right in the drawing).
The cutting blade 52 swings forward to engage with the upper end.
The rear end is pressed and moved forward, and the binding tube 30 is cut with the blade portion 52' at the tip. After the cutting is completed, the return spring 53 causes the machine to return backward. The cut tube is attached to the guide pin 43
Receive it at The guide pin with the binding tube inserted is drum 4.
It is designed to rise by rotation of 4,
The binding tube inserted into the binding hole of the document is fused to the edge of the binding hole by an upper heating plate (built in the holding plate) and a lower heating plate 45, and the binding is completed. After the stitching is completed, the drum continues to rotate, and the release roller 47 hits the screw 46 on the drum, and the connecting rod 48 to which the roller is attached moves to the pivot 4.
Using 9 as a fulcrum, pull down the joint 50. Accordingly, the pin 21 connected to this joint is also pulled down, and the stop plate 19 becomes horizontal, and the holding plate 7 is disengaged from the stop bar 17, so that the holding plate automatically rises.

As described above, the product of the present invention not only allows the dimensions of the binding tube to be determined with a simpler device than the conventional product, but also
It is extremely convenient as it can be used only for hole punching work that does not involve binding documents, and the simplified structure reduces product costs by omitting parts and shortening the manufacturing process and time. It has advantages.
