Description

  In an automatic bookbinding machine that binds documents using a binding tube as a binding rod, if the length of the resin tube remaining in the machine is less than the length required for bookbinding, the remaining resin tube is removed. The present invention relates to a discharge device that can be easily discharged.

  Conventionally, the applicant has independently developed, manufactured and sold an automatic bookbinding machine that uses a resin tube as a binding rod to bind documents. The basic principle of the paper sheet binding method in this automatic bookbinding machine is that, as shown in Patent Document 1, a resin tube of an appropriate length is inserted into a binding hole provided in a paper sheet, and both ends of the resin tube are pressed. It is made to mold a cocoon-like overhang by heating. A basic structure of an automatic bookbinding machine for automatically realizing the binding principle is as shown in Patent Document 2, for example. That is, if the structure of this automatic bookbinding machine is summarized by quoting the numbers attached to the patent gazette according to Patent Document 2, the bookbinding machine can be used for documents stacked on the base 1 for the purpose of bookbinding. A device 2 for punching a binding hole, a device 3 for supplying a resin tube for forming a binding rod to a desired length, and a device 4 for forming a binding rod by the supplied resin tube are respectively mounted. Yes.

  Among them, the device 2 for punching a spell hole in the document is provided with a lifting and lowering operation screw 21 on the frame 13 of the base 1 so as to be rotatable, referring to FIGS. A support plate 222 of a drill motor 221 provided with a drill 22 is screwed to the lifting operation screw 21 so as to be movable up and down. That is, the support plate 222 of the drill motor 221 is lowered by the rotation of the raising / lowering operation screw 21 and further lifted, and the drill 22 punches a binding hole in the documents stacked on the base 1. The rotation switching of the drive motor 211 of the lifting / lowering operation screw 21 is performed by the operation of a limit switch. As one of the operation means, as shown in FIGS. What coated the surface of the board 232 with the elastic insulating board 233 is used. In other words, a predetermined voltage is applied to the drill, the drill 22 is lowered, and the punching of the spell hole is finished on the stacked documents, and the tip of the drill 22 passes through the elastic insulating plate 233 on the lower surface of the document to the energizing plate 232. If contact is made, a strong current instantaneously flows through the drill, the limit switch is operated to reverse the rotation of the drive motor 211, and the drill 22 and the like are raised. In addition, presser fittings 24 for pressing and fixing the document are provided on the lower surfaces of both side portions of the support plate 222 of the drill motor 221, and are inserted into the lifting guide rods 223 and 223 so as to be slidable in the vertical direction. The springs 241 and 241 are inserted into the upper and lower parts of the H.223 and are elastically supported. Accordingly, the presser fitting 24 is also lowered following the lowering of the support plate 222 of the drill motor 221.

  Next, the apparatus 3 for supplying a resin pipe for forming a binding rod to a desired length will be described. Reference numeral 31 shown in FIG. It is slidably provided inside the locking housing 243. A pressing portion 317 is provided at the upper end of the supply starting rod 31 and faces the operating piece 224 protruding from the support plate 222 of the drill motor 221 with a specific interval. This specific interval is substantially the same as the interval from the tip position of the drill 22 to the lower surface of the presser fitting 24 in a normal state, and is substantially smaller than that interval, that is, when the resin tube is used as a binding rod. In addition, both ends of the resin tube are melted and deformed to reduce the length of the portion that forms the ridge. That is, the supply start bar 31 is lowered together with the locking case 243 having the rack 242 as the presser fitting 24 is lowered. When the presser bracket 24 sandwiches the stacked documents on the base 1 and stops the descent, the supply starter 31 is stopped together with the locking case 243 having the rack 242. On the other hand, the support plate 222 that supports the drill motor 221 that has lowered the presser fitting 24 continues to be lowered by the rotation of the lifting operation screw 21 even when the presser fitting 24 stops. Then, immediately before the tip of the drill 22 rotated by the drill motor 221 reaches the surface of the stacked document held by the presser fitting 24, the operating piece 224 protruding from the support plate 222 presses the supply start piece 31. The pressing starter 31 is pushed down until the drilling holes 22 are stacked in the stacked documents, and the pressing starter 31 is pressed down until the supply starter 31 has a rack 242. It slides down inside. It is clear that the distance by which the feed starter 31 descends is approximately the same length as the thickness of the stacked documents, substantially a little longer.

  The base portion of the index rope 32 is fixed to the rope winding wheel 322 and appropriately wound, and the tip end thereof is fixed to the lower end engaging piece 312 of the supply starting rod 31. Accordingly, when the supply starting rod 31 slides down, the engaging piece 312 also moves down and is separated from the engaging portion 313 of the locking housing 243, so that the index rope 32 fixed to the engaging piece 312 is Only the amount of descent is indexed. Reference numeral 33 denotes a resin tube delivery wheel that forms a binding rod, and is loosely fitted to the rotary shaft 326 of the rope take-up wheel 322 so as to face the friction wheel 331. The friction wheel 331 is supported by an eccentric shaft 332, and the lever 333 rotates the eccentric shaft 332 so that the position of the friction wheel 331 with respect to the delivery wheel 33 is approached or separated. That is, when the resin pipe is inserted between the delivery wheel 33 and the friction wheel 331, the friction wheel 331 is separated from the delivery wheel 33, and when the resin tube is sent in conjunction with another operation mechanism, the friction wheel 331 is disposed. Is caused to approach the delivery wheel 33 to sandwich the resin tube. If the delivery wheel 33 is rotated while the delivery wheel 33 and the friction wheel 331 sandwich the resin tube, the resin tube is sent out. If the size of the delivery wheel 33 is the same as that of the rope winding wheel 322, the resin pipe is sent out by the index amount of the index rope 32. When the punched holes are finished in the documents stacked by the drill 22 and the lifting guide rod 223 is lifted together with the drill 22, if the lower protrusion 357 of the lifting guide rod 223 comes into contact with the opening / closing rod 356, the base of the opening / closing rod 356. Is supported by the stopper 358, so that the opening / closing rod 356 is lifted together with the arm rod 354 as shown by a chain line in FIG. When the tip of the arm rod 354 is raised, the rotating shaft 351 of the operating piece 35 is rotated, and the locking piece 344 of the cutting blade 34 fitted to the bifurcated locking portion 353 of the operating piece 35 is retracted. The cutting blade 34 is moved to one side of the supply port 343, and the resin tube protruding from the supply port 343 is cut. The resin tube cut by the cutting blade 34 falls downward, and is supplied to and supported by the receiving needle 36 positioned in the lower side in advance.

  Next, a description will be given of the apparatus 4 for forming a staple with the supplied resin tube. The resin tube is formed on the staple by pressing the upper and lower portions of the resin tube with the upper heating die 41 and the lower heating die 42. The upper and lower end portions are melted and deformed to form a ridge. That is, the upper heating die 41 is slidably provided with respect to the inner lower surface of the presser fitting. When the drill 22 pierces a binding hole, the upper heating die 41 moves backward so as not to obstruct the passage of the drill 22 and is bound by a resin tube. When forming a collar, the drill 22 is advanced to the position of the spell hole in which the drill 22 is drilled. The upper heating die 41 is slid 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 floor plate 23 is slid back and forth. 15 is opened and closed. That is, the floor plate 23 is provided to advance to a position opposite to the drill 22 that descends when the drill 22 drills a spell hole, contrary to the upper heating die 41 that slides back and forth inside the presser fitting 24. When the resin tube is inserted into the spelled hole to form a binding rod, it is retracted to open the through hole 15 of the base 1. The lower heating die 42 is supported by the rotation support plate 421 so as to reciprocally rotate between the resin tube supply position for binding and the position of the through hole 15 where the binding hole is opened. It operates in conjunction with the operation of the lever 43. Thereafter, the lower heating die 42 is raised, and the resin tube fitted to the center receiving needle 36 is inserted into the binding hole from the lower side so as to contact the upper heating die 41 and further pressed. Then, as shown in FIG. 14 of the same publication, the upper and lower portions of the resin tube are melted and deformed by the upper heating die 41 and the lower heating die 42 to form a fold, thereby binding the book using the resin tube as a binding rod. Complete.

  In the current automatic bookbinding machine, the operation lever 43 is eliminated and the entire process is automated. That is, a series of processes are automatically performed continuously by an internal control mechanism. And also about the apparatus 3 which supplies the resin tube for forming the staple related to this invention to desired length, the improvement is added as follows. This will be described with reference to FIG. 5 attached, and basically, an operation similar to that of the apparatus 3 is performed. First, when a drill and a drilling motor (not shown) begin to descend, the tube (resin pipe) entrance opens. When the tube cutting shaft inside the main shaft interlocked with the motor base opens the claw, the cutter operating lever slides the cutter forward by the contraction force of the tension spring, and the tube entrance is opened. The cutter not only cuts the tube but also serves as a door for the tube entrance. Then, when the holding arm is lowered and the document is fixed, the length of the tube is determined. That is, when the pressing arm is lowered, the tube length detecting plate connected by the wire is raised, and the position of the tube length detecting plate is determined when the pressing arm fixes the document. The length of the tube that changes depending on the thickness of the document is set to a length B obtained by adding 14 mm to the portion where the tube is caulked to the thickness A of the document. That is, the length from the position of the cutter to the position of the tube length detection plate is determined as the length of the tube. Subsequently, tube feed begins when the drill penetrates the document and reaches the energizing plate. The tube feed motor is driven, and the tube is fed into the guide pin by the feed roller and reaches the tube length detection plate. Even after the tube reaches the detection plate, the roller is idle. Further, when the drill is turned upside down and returned to the original position, the tube is cut. That is, the tube feed motor stops, the tube cutting shaft catches the claw, and the cutter slides backward by the cutter operating lever to cut the tube, and at the same time closes the tube entrance. Through this series of operations, a tube (resin tube) cut to an accurate length is supplied to the guide pin and is inserted and supported.

  The present invention presupposes an automatic bookbinding machine having the above-described configuration and operation, and solves the above-described problems relating to the handling of a resin tube (tube) as a staple.

  That is, the automatic bookbinding machine automatically measures the thickness of a document, cuts out a resin tube having an appropriate length, and heats both ends of the resin tube with heat to bind the document. In this case, the length of the resin tube is monitored via a sensor, and when the length of the resin tube is insufficient with respect to the thickness of the document, the machine does not operate. It informs you that the length of the resin tube is not enough. Therefore, the user needs to remove the shortened resin tube and supply a new long resin tube.

  Conventionally, the operation of removing the remaining resin pipe is performed by inserting a pull-out rod, which is a dedicated tool for taking out the resin pipe, into the hole for supplying the resin pipe provided on the top surface of the bookbinding machine body, and using the tapered tip of the resin pipe. It was inserted into and hooked, and the remaining resin tube was pulled out. That is, a dedicated instrument is required for taking out the resin tube. In addition, since the dedicated instrument is long and the insertion position is the top surface of the bookbinding machine main body, the operation of taking out the remaining resin tube is a very laborious operation. Furthermore, since the dedicated instrument is tapered, there is a risk of injury, and care must be taken when handling it. Furthermore, since the length of the remaining resin pipe cannot be confirmed from the outside and is taken out when it is less than the thickness at the time of binding thickness measurement, it may be used as it is at a thinner binding thickness. It was difficult and sometimes wasted.

  The present invention has been made to solve such a problem, and an object of the present invention is to allow the residual resin pipe to be discharged by a simple lever operation.

  In order to solve the above-mentioned problem, the invention according to claim 1 of the present invention is such that a resin tube bracket is rotatably attached to a resin tube feed base standing on a base of an automatic bookbinding machine via a rotation shaft. A discharge lever is attached to the rotating shaft, a resin pipe holding pipe communicating with the resin pipe guide pipe is provided on the resin pipe bracket, and a resin pipe presence / absence detection sensor is provided at a predetermined position of the resin pipe holding pipe. When the presence / absence detection sensor cannot detect the presence of the resin pipe and determines that the resin pipe is short, the resin pipe feed roller is reversed via an appropriate control device to return the remaining resin pipe into the resin pipe holding pipe and the user. The discharge device is configured such that when the discharge lever is operated, the resin tube bracket rotates to drop the remaining resin tube in the resin tube holding pipe onto the resin tube discharge guide. It is obtained by adopting the means of.

  Further, in the invention described in claim 2, in the discharge device, when the remaining resin pipe returns into the resin pipe holding pipe, the resin pipe holding roller is pressed by the spring toward the resin pipe feeding roller, and the roller arm is interposed. The microswitch is turned off, the resin tube feed roller is stopped via the control device, and the user is urged to operate the discharge lever.

  When the resin pipe presence / absence detection sensor determines that the resin pipe in the machine is shorter than the specified length, the residual resin pipe discharging device having the above configuration reverses the resin pipe feed roller to return the residual resin pipe into the resin pipe holding pipe. At the same time, the user is prompted to operate the discharge lever. As a result, when the user operates the discharge lever, the resin tube bracket provided with the resin tube holding pipe rotates, and the remaining resin tube is free-falling to the resin tube discharge guide. It is now possible to discharge the remaining resin tube by a simple lever operation without using a special jig.

  Further, since the length of the resin pipe is detected by the sensor and the remaining resin pipe having a predetermined length or less is discharged, the resin pipe can be used without waste.
