The present invention relates to an automatic bookbinding machine that binds documents by using a resin pipe as a bar, and more particularly, to easily discharge the remaining resin pipe when the length of the resin pipe remaining in the machine is insufficient for the bookbinding. It is about one discharge device.

Applicants of the present invention have conventionally developed, manufactured, and sold an automatic bookbinding machine in which a booklet is bound using a resin pipe as a bar. As shown in Japanese Patent Publication No. 53-5574, the basic principle of the method of iron sheet binding in this automatic bookbinding machine is to insert a synthetic resin pipe of an appropriate length into an iron hole provided in the sheet leaf. Both ends of the resin tube are heated in a pressing mold to be molded into a release prevention jaw shape. The basic structure of the automatic bookbinding machine for automatically realizing such a binding principle is as shown in, for example, Japanese Patent Publication No. 55-25076. That is, when the structure of this automatic bookbinding machine is summarized by citing the number given to the patent publication related to Japanese Patent Publication No. 55-25076, the bookbinding machine is applied to the laminated documents for the purpose of binding the base plate 1. An apparatus 2 for drilling holes, an apparatus 3 for supplying a resin tube for forming iron with a desired length, and an apparatus 4 for forming iron with the supplied resin tube are provided.

Among them, the apparatus 2 for drilling iron holes in the document is a lifting and lowering operation screw 21 on the edge 13 of the base plate 1, as shown in FIGS. 1 to 3 of Japanese Patent Publication No. 55-25076. ) Is rotatably mounted, and the support plate 222 of the drill motor 221 including the drill 22 is screwed to the lifting operation screw 21 so as to be liftable. That is, the support plate 222 of the drill motor 221 is lowered and raised again by the rotation of the lifting operation screw 21, so that the drill 22 drills an iron hole in the document laminated on the base plate 1. The rotation switching of the drive motor 211 of the elevating operation screw 21 is carried out by the operation of a limit switch. As one of the operation means, FIGS. 4 and 5 of Japanese Patent Publication No. 55-25076 As shown in FIG. 5, what covered the surface of the electricity carrying plate 232 with the elastic insulating board 233 is used. That is, a predetermined voltage is applied to the drill, and the drill 22 descends and the perforation of the iron hole is finished in the stacked document, and the tip of the drill 22 passes through the elastic insulating plate 233 on the lower surface of the document, and the conduction plate 232 is applied. ), Instantaneously strong current flows through the drill, and the limit switch is operated to reverse the rotation of the driving motor 211 to raise the drill 22 and the like. In addition, pressing molds 24 for pressing and fixing the documents are installed on the lower surface of both sides of the support plate 222 of the drill motor 221, and are fitted so as to slide up and down with respect to the lifting guide bars 223 and 223. Springs 241 and 241 are inserted into upper and lower portions of the liver 223 and 223 to elastically support them. Accordingly, the pressing die 24 is also lowered by the lowering of the support plate 222 of the drill motor 221.

Next, a description will be given of an apparatus 2 for supplying a resin tube for forming a steel bar by a predetermined length, and reference numeral 31 shown in Fig. 7 of Japanese Patent Publication No. 55-25076 serves as a starter tube for supplying a rack ( 24 is provided so as to be slidable inside the U-shaped locking interceptor 243. The press part 317 is provided in the upper end of this supply starting period 31, and opposes at a specific space | interval with respect to the operation piece 224 which protruded on the support plate 222 of the drill motor 221. As shown in FIG. This particular spacing is almost equal to the spacing from the tip position of the drill 22 to the lower surface of the pressing die 24 in a normal state, and is substantially smaller than the spacing, that is, when the resin pipe is made of iron. Both ends of the resin tube are melted and deformed by the length of the portion forming the separation prevention jaw. That is, the supply starting time 31 descends together with the locking element 243 having the rack 242 along with the lowering of the pressing die 24. That is, when the pressing mold 24 stops the descent by clamping the documents stacked on the base plate 1, the starting timing 31 for the supply together with the locking body 243 having the rack 242 is also present. Stop. On the other hand, the support plate 222 which supports the drill motor 221 which lowered the pressing die 24 down continues by the rotation of the lifting operation screw 21, even if the pressing die 24 stops. Then, the working piece 224 protruding from the support plate 222 immediately before the tip of the drill 22 rotating by the drill motor 221 reaches the surface of the stacked document held by the pressing mold 24 is supplied. The drill 22, which descends in contact with the pressing portion 317 of the starting timing 31, drills an iron hole in the laminated document, and pushes down the pressing portion 317 until the end is finished, and the starting timing 31 for supplying Sliding down the inside of the holding member 243 having a rack 242. The descending distance of the start time 31 for supplying is about the same length as the thickness of the laminated document, and it is preferable that it is substantially longer than this.

The base of the index rope 32 is fixed to the rope winding car 322 and wound appropriately, and its front end is attached to the lower step piece 312 of the start time 31 for supply. Therefore, when the supply starting time 31 slides and falls, the engagement piece 312 is also lowered and the gap between the engaging portions 313 of the engagement element 243 is increased so that the engagement piece 312 is fixed to the engagement piece 312. The index rope 32 is indexed only for the drop. Reference numeral 33 denotes a delivery vehicle of a resin pipe forming steel, which is freely fitted so as to be rotatable with respect to the rotation shaft 326 of the rope winding car 322, and is provided to face the friction difference 33l. The friction wheel 331 is supported by the eccentric shaft 332, and by rotating the eccentric shaft 332 by the lever 333, the position of the friction wheel 33l with respect to the delivery vehicle 33 is approached or Make a separation. That is, when the resin pipe is inserted between the delivery vehicle 33 and the friction difference 331, the friction difference 331 is separated from the delivery vehicle 33, and when the resin tube is interlocked with another operation mechanism to send out the resin tube. The friction wheel 331 is brought close to the delivery vehicle 33 to sandwich the resin pipe. When the delivery vehicle 33 is rotated while the delivery vehicle 33 and the friction vehicle 331 sandwich the resin tube, the resin tube is sent out. If the size of the delivery vehicle 33 is the same as that of the rope winding car 322, only the index amount of the indexing rope 32 is sent out. When the punching of the iron hole is finished in the documents stacked by the drill 22 and the lifting guide bar 223 rises together with the drill 22, the lower protrusion 357 of the lifting guide bar 223 opens and closes 356. ), Since the base of the opening and closing section 356 is supported by the stopper 358, the opening and closing section 356 ascends simultaneously with the arm section 354, as shown by the broken line in FIG. As the tip of the arm 354 rises, the rotating shaft 351 of the operating piece 35 rotates, and the locking piece of the cutting knife 34 fitted to the secondary phase stop portion 353 of the operating piece 35 ( 344 is retracted to move the cutting knife 34 to one side of the supply port 343 to cut the resin tube protruding from the supply port 343. The resin pipe cut | disconnected by the cutting knife 34 falls below, and is supplied and inserted in the support 36 previously located below.

Next, a description will be given of an apparatus 4 for forming iron by the supplied resin pipe. The resin pipe is formed in the upper and lower portions of the resin pipe by the upper heating mold 41 and the lower heating mold 42. The upper and lower ends thereof are pressed and deformed, respectively, to be executed by the separation prevention jaw shape. That is, the upper heating mold 41 is provided so as to be slidable with respect to the inner lower surface of the pressing die. When the drill 22 drills the iron hole, the upper heating mold 41 is retracted so as not to obstruct the passage of the drill 22, and the resin tube is retracted. When forming the iron, the drill 22 is advanced to the drilled hole position. While the sliding of the upper heating die 41 is performed by the operation of the operation lever 43, at the same time, the arm 44 is rotated in conjunction with the movement of the operation lever 43, and the subplate 23 is slid back and forth. The through hole 15 of the base plate 1 is opened and closed. That is, the subplate 23 is installed by moving forward to the opposite position of the drill 22 which descends when the drill 22 drills the iron hole, as opposed to the upper heating die 41 which slides back and forth inside the pressing mold 24. When the resin pipe is inserted into the drilled hole to form the steel, the reinforcing hole 15 of the base plate 1 is opened. In addition, the lower heating mold 42 is supported by the rotation support plate 421 so as to reciprocate the resin pipe supply position for the iron and the opening 15 position of the iron hole, which is also operated by the operation lever 43. It works in conjunction with. Thereafter, the lower heating mold 42 is raised to insert the resin tube fitted to the central support 36 from the lower side with respect to the perforation so as to contact the upper heating mold 41 and press it further. As shown in FIG. 14, the upper and lower parts of the resin tube are melt-deformed by the upper heating mold 41 and the lower heating mold 42 to form a release prevention jaw, thereby forming bookbinding as the steel tube by iron. To complete.

In the present automatic bookbinding machine, the operation lever 43 is closed and all the strokes are automated. That is, a series of processes are continuously and automatically performed by the built-in control mechanism. In addition, the apparatus 3 for supplying a predetermined length of the resin pipe for forming the steel sheet according to the present invention is also improved as follows. Referring to this attached FIG. 5, basically, an operation similar to the apparatus 3 is performed. First, when the drill and hole opening motor (not shown) starts to descend, the tube (resin tube) inlet is opened. When the shaft for cutting a tube in the main shaft interlocking with the motor base opens the saw blade, the cutter operating lever rides the cutter to the base by the force of the tension spring to open the inlet of the tube. The cutter not only cuts the tube but also acts as a door to the tube entrance. Then, the push arm is lowered and the length of the tube is determined when the document is fixed. That is, when the push arm is lowered, the tube length detection plate connected by the wire is raised, and the position of the tube length detection plate is determined when the push arm fixes the document. The length of the tube changed by the thickness of the document is set to the length B of the document A, the portion of which the tube is caulked, and 14 mm. That is, the position from the position of the cutter to the position of the tube length detection plate is determined as the length of the tube. Subsequently, when the drill passes through the document and reaches the current carrying plate, the tube transfer starts. The tube feed motor is driven and the tube is sent to the guide pin by the feed roller to reach the tube length detection plate. The roller is idle even after the tube reaches the detection plate. In addition, the tube is cut when the drill reverses and returns to its original position. That is, the tube feed motor stops, the tube cutting shaft hangs the saw blade, the cutter is rear-base-ride by the cutter operating lever to cut the tube, and at the same time the inlet of the tube is closed. By this series of operations, the tube (resin tube) cut to the correct length is supplied to the guide pin to be depressurized and supported.

This invention presupposes the automatic bookbinding machine which has the structure and operation | movement mentioned above, and solves the subject regarding the handling of the resin pipe (tube) mentioned above as iron.

That is, the automatic bookbinding machine automatically measures the thickness of the document, cuts out a resin tube of an appropriate length, and copes both ends of the resin tube with heat to bind the document. In this case, when the length of the resin tube is monitored through a sensor and the length of the resin tube is insufficient for the thickness of the document, the machine does not operate, for example, the length of the resin tube is displayed to the user by the lighting of a warning lamp. It is supposed to announce the lack. Therefore, the user needs to remove the reduced resin tube and supply a new long resin tube.

The operation of removing the residual resin pipe is made by inserting a drawing rod, which is a device for exclusively dispensing the resin pipe, into a hole for resin pipe supply, which is conventionally installed on the upper surface of the main body of the bookbinding machine, and inserting the tapered tip into the resin pipe. I put it on, and I pulled out the residual resin pipe. That is, a dedicated mechanism was necessary for taking out the resin tube. Moreover, since this dedicated mechanism was long and the insertion position became the upper surface of the bookbinding machine main body, the extraction operation of the remaining resin tube was a very instant operation. In addition, since the dedicated mechanism has a thin tip shape, there is a risk of injury and care must be taken for its handling. In addition, if the length of the remaining resin tube is not confirmed from the outside and is not satisfied with the thickness at the time of iron thickness measurement, it may be used as it is in the case of thinner iron, so that the effective use of the resin tube It was difficult and sometimes wasted.

The present invention has been made to solve such a problem, and an object thereof is to enable the discharge of the remaining resin pipe by simple lever operation.

The present invention for solving the above problems, the resin pipe bracket installed in the base plate of the automatic bookbinding machine through the rotating shaft to be installed rotatably, the discharge shaft is attached to the rotating shaft, the resin pipe A resin pipe holding pipe is installed in the bracket to communicate with the resin pipe guide pipe, a resin pipe presence sensor is installed at a predetermined position of the resin pipe holding pipe, and the resin pipe presence sensor detects the presence of the resin pipe. If it is determined that the resin pipe is short, the resin pipe feed roller is reversed through an appropriate control device, the remaining resin pipe is returned to the resin pipe holding pipe, and the user is urged to operate the discharge lever to operate the discharge lever. The resin pipe bracket is rotated to discharge the remaining resin pipe in the resin pipe holding pipe to the resin pipe discharge guide. It employs a means of constituting an apparatus.

In the above discharging device, when the remaining resin pipe is returned to the inside of the resin pipe holding pipe, the resin pipe pressing roller is pushed to the resin pipe feed roller by a spring, and the micro switch is turned off via the roller arm. And a means for stopping the resin pipe feed roller through the control device and for prompting the user to operate the discharge lever.

Next, the operation of the discharge device of the remaining resin pipe will be described. In the series of bookbinding operations, the resin pipe is cut to the length necessary for bookbinding by the cutter blade 15, and is transferred to the resin pipe guide pin 12. The coating operation is performed by heat and after bookbinding, the resin tube guide pin 12 returns to its original position (state of FIG. 2). At this time, the resin tube presence sensor 9 detects the presence or absence of the resin tube (T), the upper end of the resin tube (T) is located below the sensor (9) can detect the presence of the resin tube (T). If it is judged that the length is shorter than the prescribed length, the resin tube discharge lamp (not shown) of the operation panel (not shown) installed in the front of the bookbinding machine through an appropriate control device (not shown) flashes and the user can Inform the branch is short. At this time, the next binding operation is not executed. At the same time, the resin pipe feed motor controlled by the control device is operated so that the resin pipe feed roller 10 is reversed to return the remaining resin pipe upward.
