Description

  The present invention relates to a bookbinding machine that uses a sheet as a booklet, for example.

  Conventionally, when a small-size sheet such as a color sample book is bound as a booklet, the sheets are collated and bound by rivets or the like.

  Various types of binding devices, such as signatures of normal size (B5 to B4), are provided, but they are as small as a color sample book (for example, width 50 mm x length 215 mm x height No special bookbinding machine exists.

  In addition, various types of binding devices are available for bookbinding. For example, considering the function as a sample book, for example, the bound color sample book is separated and a part of the color sample paper used is taken out. Again, it was necessary to easily assemble it into a bookbinding state, and it was impossible to achieve this function with ordinary rivets.

  As such a rivet that can be easily assembled again by releasing the booklet, a detachable screwed rivet is provided (see Patent Document 1).

  The above-described removable threaded rivet comprises a T-shaped female rivet having a thin caulked portion at one end and a screw hole formed at the other end, and a male rivet having a rivet head. A female rivet is inserted into a communicating rivet hole provided in a plurality of plate-shaped articles to be caulked from one side, and a male rivet is screwed into a screw hole of the female rivet from the other side and caulked. When the male rivet is screwed into the female rivet, a screwdriver is engaged with the groove provided in the rivet head of the male rivet.

  By using the above-described threaded rivet as a booklet binding tool, a user of the booklet can disassemble the booklet and easily assemble it again.

  However, in the bookbinding process, screwing one by one with a screwdriver is inefficient as an actual work, leading to an increase in bookbinding costs.

A transport station 5 that transports the booklet 101 by releasing it from the fixing device 8 is provided.

  The processes executed at each station are arranged radially at equal intervals around the rotation axis 9 of the turntable 6 in the order of the bookbinding process.

  An input device 7 for inputting an operation after an operator who performs a sheet feeding operation feeds the sheet 100 is disposed in the sheet feeding station 2, and the punching station 3 and the rivet hole that has been drilled remain in the punching station 3. The transfer station 5 is provided with a blower 35 that blows off the perforated pieces with air.

  The caulking station 4 includes a caulking device 41, a male rivet parts feeder 45 and a female rivet parts feeder 46 provided on both sides of the caulking device 41, and a male rivet supply rail that connects the caulking device 41 and the parts feeders 45 and 46. 451 and a female rivet supply rail 461.

  Further, in the vicinity of the outer peripheral portion of the upper surface of the turntable 6, four fixing devices 8 of the same number as the number of bookbinding steps are provided radially at equal intervals around the rotation shaft 9 of the turntable 6 so as to correspond to each station. Yes.

  Thereby, each fixing device 8 can operate a process in all the stations by a series of flow work simultaneously, and bookbinding time is shortened.

  Next, the input device 7 and the display unit 71 will be described together with an enlarged plan view of the input device 7 and the display unit 71 shown in FIG.

  The input device 7 includes an operation switch 72 and an emergency stop button 73 having an operation button that is slightly larger than the operation button of the operation switch 72, and the display unit 71 includes a display screen 74 that digitally displays the number of operations.

  After the sheets 100 (FIG. 1) stacked on the fixing device 8 (FIG. 1) are fed from the paper feeding station 2 (FIG. 1) outside the turntable 6 (FIG. 1) by the operator, the operator's left hand By pressing the operation switch 72 of the input device 7 arranged on the side, all processes are simultaneously performed at each station.

  After each process is completed, the turntable 6 rotates 90 degrees counterclockwise in plan view and stops in order for the fixing device 8 to advance to the next station.

  As a result, the operator can centrally manage all the devices at each station, and the number of operations is displayed on the display unit 71, so that the bookbinding cycle can be easily grasped.

  Next, the fixing device 8 will be described together with a plan view of the fixing device 8 shown in FIG.

  The female rivet press-fitting device 42 includes a drive unit 421 that engages with the rail pipe 411 and travels horizontally along the rail pipe 411, and an extendable telescopic cylinder 422 having an insertion pin 423 at the tip.

  The male rivet press-fitting device 43 includes a telescopic cylinder 422 for inserting the male rivet 401 into the rivet hole 300 by pushing it upward from below.

  In the caulking device 41 configured in this way, first, the female rivet insertion device 42 moves from the initial position a along the rail pipe 411 to the female rivet supply position b in FIG.

  At this time, the female rivets 402 are supplied from the female rivet parts feeder 46 while being aligned in a row and moved on the female rivet supply rail 461, and are supplied substantially vertically on the female rivet supply base 424 with the caulking portion 4022 facing upward. ing.

  Next, the female rivet insertion device 42 moved to the female rivet supply position b extends the telescopic cylinder 422 downward, the insertion pin 423 extends upward from the screw hole 4021, and the lower surface of the flange portion 4221 faces the upper surface of the caulking portion 4022. The female rivet 402 is locked to the insertion pin 423 by friction between the inner surface of the screw hole 4021 and the outer periphery of the insertion pin 423.

  Subsequently, the female rivet insertion device 42 retracts the telescopic cylinder 422 upward while holding the female rivet 402 to the insertion pin 423, lifts the female rivet 402, and reaches the caulking position c (FIG. 11) along the rail pipe 411. Moving. At this time, the next female rivet 402 supplied by moving the female rivet supply rail 461 is supplied to the female rivet supply base 423.

  In the male rivet guide 44, a male rivet 401 that has been moved by aligning male rivet supply rails 451 in a vertical row from a male rivet parts feeder 45 is disposed.

  11 is an enlarged plan view of the ends of the male rivet guide 44 and the male rivet supply rail 451 shown in FIG. 11, a BB sectional view of the male rivet guide 44 shown in FIG. 12, and a screwed rivet 400 shown in FIG. The male rivet guide 44 and the caulking device 41 in the caulking state will be described together with a right side view of the caulking device 41 in the caulking state and an AA sectional view (FIG. 10) of the caulking device 41 in the same state shown in FIG. .

First, the male rivet guide 44 will be described in detail.
The male rivet guide 44 is a square pillar having a substantially square shape in plan view, and has a substantially C-shaped space in plan view larger than the outer periphery of the rivet head 4012 of the male rivet 401, and the male rivet guide rail 451 side of the space. Has an opening 444 through which the rivet head 4012 can pass.

  Further, on the upper surface of the male rivet guide 44 facing the opening 444, a passage recess 443 through which the rivet head 4012 of the male rivet 401 protrudes from the lower portion of the booklet 101 when the booklet 101 is locked is provided.

  Two vertical contact portions 442 are provided on the side surface of the space as a guide for guiding the press-fitting direction when the male rivet 401 is moved upward by the telescopic cylinder 422 of the male rivet press-fitting device 43.

  The vertical abutting portion 442 has a convex shape in a plan view in which a corner portion abuts on the outer periphery of the rivet head 4012, and is continuously formed from the bottom of the inner surface of the guide 44 to the lower end of the passage recess 443.

  Further, the vertical contact portion 442 is provided at two positions on the side surface opposite to the opening 444 at right angles to the axial direction of the male rivet supply rail 451, and the interval between the two vertical contact portions 442 is the rivet head. It is smaller than the diameter of the portion 4012.

  As a result, the axis of the screw portion 4011 of the male rivet 401 in contact with the vertical contact portion 442 coincides with the axis of the screw hole 4021 of the female rivet 402, and the male rivet 401 and the female rivet 402 can be engaged without failure. Can be combined.

  Further, even when the burr 4013 formed at the time of manufacturing the male rivet 401 remains on the outer peripheral portion of the rivet head 4012, the burr 4013 interferes with the guide inner surface when the male rivet 401 is moved upward, and is displaced from the press-fitting position. Thus, the screwed rivet 400 can be prevented from failing, deforming, or breaking.

  Even if the burr 4013 once contacts the vertical contact portion 442, the male rivet 401 rotates and the burr 4013 deviates from the vertical contact portion 442 because the burr 4013 is in point contact with each vertical contact portion 442. The rivet head 4012 and the vertical contact portion 442 come into contact with each other, so that reliable positioning can be performed.

Next, the female rivet insertion device 42 will be described in detail.
The female rivet insertion device 42 moves to the caulking position c, extends the telescopic cylinder 422 downward with the female rivet 402 locked to the insertion pin 423, and caulks the female rivet 402 on the lower surface of the flange 4221 (FIG. 7). The female rivet 402 is inserted into the rivet hole 300 from above by pressing the portion 4022 (FIG. 7).

  Accordingly, the surface of the caulking portion 4022 is pressed by the surface of the flange portion 4221, and the breakage and deformation of the female rivet 402 can be prevented.

  At the same time, the male rivet 401 is inserted into the rivet hole 300 by extending the telescopic cylinder 422 of the male rivet press-fitting device 43 from below and press-fitted into the female rivet 402.

  At this time, the male rivet 401 is moved upward along the outer periphery of the rivet head 4012 of the male rivet 401 along the two vertical contact portions 442 of the male rivet guide 44 and engaged with the female rivet 402.

  After completion of the engagement between the male rivet 401 and the female rivet 402, the respective telescopic cylinders 422 are contracted to return to the initial position a (FIG. 8).

  After each telescopic cylinder 422 returns to the initial position a, the operator operates the input device 7 (FIG. 2), so that the booklet 101 moves to the next station 5 by the rotation of the turntable 6. Sometimes the rivet head 4012 of the male rivet 401 protruding from the lower surface of the booklet 101 passes through the passage recess 443 provided on the upper surface of the male rivet guide 44.

  Next, the conveyance device 51 will be described together with a plan view of the conveyance device 51 in a state where the booklet 101 is held by the grip 52 shown in FIG.

  The transport device 51 includes a grip 52, a rail 53 on which the grip 52 travels, and a chute 54 that slides the booklet 101 transported by the grip 52.

  The grip 52 includes an upper grip 521, a lower grip 522, and a side grip 523 that sandwich the booklet 101, and can travel on the rail 53.

  The rail 53 has a length that allows the grip 52 to extend from the clamping position B to the release position C, and includes a chute 54 at the release position C.

  First, after the rotation of the turntable 6 is completed, the grip 52 travels on the rail 53 from the initial position A, moves to the clamping position B, and clamps the booklet 101. Simultaneously with gripping of the grip 52, the fixing of the booklet 101 by the fixing device 8 is released.

  Subsequently, the grip 52 travels on the rail 53 toward the chute 54 side while holding the booklet 101 and moves. After arriving at the release position C, the holding of the booklet 101 is released, and the booklet 101 is carried out by sliding on the chute 54.

  After the booklet 101 is nipped and released, the grip 52 moves to the initial position A to prepare for the next step.

  Thereby, the booklet 101 which completed all the processes is automatically conveyed from the turntable 6. FIG.

  Next, the control of the booklet binding machine 1 will be described based on the block diagram shown in FIG.

First, after the operator feeds the stacked sheets 100 on the fixing device 8 (FIG. 1) at the paper feeding station 2, the operator presses the operation switch 72 (FIG. 2) of the input device 7.
An input signal input by the operator is transmitted to the control unit 61 and the fixing means position detection device 64.

  The fixing means position detection device 64 detects the position of each of the four fixing devices 8 and transmits the detection result to the control unit 61.

  The control unit 61 that has received the input signal causes the display unit 71 to display the number of operations obtained by adding one operation of the current operation to the number of operations up to the previous time, and causes the punching device 31, the caulking device 41, and the transport device 51 to display each device. The operation signal of is transmitted.

  In addition, the control unit 61 that has received the detection result of the fixing unit position detection device 64 transmits operation signals such as pressurization, holding, and decompression to the compressor 62 based on the detection result.

  More specifically, the four fixing devices 8 are fixed devices 8a to 8d, respectively. The fixing device 8a is in the sheet feeding station 2, the fixing device 8b is in the punching station 3, the fixing device 8c is in the caulking station 4, and the fixing device 8d is in It is assumed that the presence at the transfer station 5 is detected by the fixing means position detection device 64.

  Here, the compressor 62 has five systems corresponding to the respective fixing devices 8a to 8d and the blower 35, and each system is connected to the fixing devices 8a to 8d and the blower 35, respectively. (Not shown), each system can be independently pressurized and depressurized.

  For the paper feeding station 2, the control unit 61 transmits a pressure signal for operating the side pressing jig 83 and the upper surface holding jig 84 by pressurizing the air pressure to the system connected to the fixing device 8 a of the compressor 62. .

  For the drilling station 3 and the caulking station 4, the control unit 61 transmits a signal for maintaining air pressure to the system connected to the fixing device 8b and the fixing device 8c of the compressor 62, and drills the punching device 31 and the caulking device 41, respectively. Signals and caulking signals are transmitted.

  For the transfer station 5, the control unit 61 first moves the grip 52 from the initial position A (FIG. 15) to the holding position B (FIG. 15) and transmits a running signal for holding the booklet 101 to the transfer device 51. Subsequently, after sending a pressure reducing signal for releasing the fixation of the booklet 101 by reducing the pressure to the system connected to the fixing device 8d of the compressor 62, the grip 52 is moved again to the release position C (FIG. 15) to the conveying device 51. Then, a release signal for releasing the holding of the booklet 101 is transmitted.

  After the operation of each station is completed, the control unit 61 transmits a rotation signal for rotating the turntable 6 by 90 degrees counterclockwise in plan view to the motor 63 of the turntable 6, so that the fixing device 8 b moves directly below the blower 35. A pressurizing signal is transmitted to the system of the compressor 62 connected to the blower 35 at the passing timing, and one bookbinding cycle is completed.

  With the above control, the bookbinding machine 1 can centrally manage all processes in each station, and the operator can synchronize all processes simultaneously at the optimal timing without making efforts to eliminate time loss. Since the process can be performed, the bookbinding cost can be reduced.

  When the operator confirms that a failure has occurred in any station, the operator presses the emergency stop button 73 (FIG. 2), and the control unit 61 that has received the emergency stop signal forcibly stops each device. Send a signal.

  As a result, the operator does not operate each device in a timely manner by looking at the operation status of each device, but only operates the input device 7 for all the steps required for one bookbinding cycle. Since it can be operated at an optimum timing, the bookbinding cycle can be shortened.

  Further, a suction device may be provided at the lower end of the telescopic cylinder 422 instead of the insertion pin 423.

  Furthermore, the side pressing jig 83 and the upper surface holding jig 84 of the fixing device 8 may be operated by a motor instead of the air pressure of the compressor 62.

  Further, in the present embodiment, one compressor 62 is divided into five systems, but five separate compressors 62 may be provided.

  Thereby, even the female rivet 402 in which the screw hole 4021 does not penetrate to the caulking portion 4022 can be moved from the female rivet supply position b (FIG. 8) to the caulking position c (FIG. 13).
