A pair of linear shafts 60 provided on the support bracket 58 so as to be capable of reciprocating left and right, and a slave unit side provided at an intermediate position on the left and right of the pair of linear shafts 60 in plan view and having an output rod connected to a tip support part 59 It consists of an electric cylinder 61 and the like. Although illustration is omitted, rubber pads for preventing damage to the support rod 1 and the tip support portion 59 are provided at the left and right central portions of the bottom surface of the tip support portion 59 and the like.

  The tip support portion 59 is moved up and down by the lifting operation mechanism 62 and moved back and forth by the cordless handset-side electric cylinder 61, and when the support rod 1 is inserted into the roll-shaped article A, and the support rod 1 is detached from the roll-shaped article A. When this is done, the end portion 1F (hereinafter also referred to as the front end portion 1F) on the side of the slave unit 9B can be supported downward in the direction in which the master unit 9A and the slave unit 9B of the support rod 1 are arranged. The position control of the tip support portion 59 is controlled by the support rod insertion / removal device controller H2 based on the amount of displacement from the origin position of the slave unit side electric motor M7 included in the slave unit side electric cylinder 61 and the lifting operation mechanism 62. Is done.

  The slide chuck device 30 and the auxiliary guide 31 of the main unit 9A of the support rod inserting / removing device 9 and the guide unit 56 of the sub unit 9B are vertically raised from the lifting / lowering loading position by the lifting / lowering device 8 and are positioned at the upper limit position PAH. In order to enable the support rod 1 to be inserted into and removed from the roll-shaped article A, the installation position is such that the horizontal center position in plan view of each device coincides with the horizontal center position in plan view of the roll-shaped article A located at the upper limit position PAH. Has been adjusted.

  The insertion / removal operation of the support bar 1 by the support bar insertion / removal device 9 will be briefly described with reference to FIG. First, in the insertion operation of the support bar 1, immediately before the insertion starts, the slide chuck device 30 is positioned at the clamping body operation position P2 set slightly in front of the backward limit P1, and the auxiliary guide 31 is positioned at the support position. ing. That is, the root portion 1N of the support rod 1 is supported by the slide chuck device 30, and a portion slightly closer to the root side than the tip portion 1F of the support rod 1 is supported by the support portion 55T in the auxiliary guide 31 (FIG. 10A). )reference). When the insertion operation is started by rotating the electric motor M2 from this state, the slide chuck device 30 moves forward to the takeover setting position P3 close to the auxiliary guide 31, and the distal end portion 1F is located on the side of the slave unit 9A. When the fixed amount is projected, the rotation operation of the electric motor M2 is stopped and the slide chuck device 30 is stopped to temporarily stop the insertion operation (see FIG. 10B). After supporting the tip 1F of the support rod 1 by the tip support portion 59 of the slave unit 9B without moving the support rod 1, the support portion 55T of the auxiliary guide 31 is lowered to the standby position, and the master unit 9A The root portion 1N is in a state where the tip portion 1F is supported by the slave unit 9B. Then, the electric motor M2 is rotated again to resume the forward movement of the slide chuck device 30 and advance to the forward limit P4 (see FIG. 10C). At this time, the electric cylinder 61 of the slave unit 9B is shortened to synchronize the tip support portion 59 of the slave unit 9B with the advance of the slide chuck device 30.

  Next, in the detachment operation of the support bar 1, immediately before the start of the detachment operation, the slide chuck device 30 is positioned at the forward limit P4, the auxiliary guide 31 is positioned at the standby position, and the base portion 1N of the support bar 1 is positioned at the slide chuck. It is supported by the device 30, and the distal end portion 1F of the support bar 1 is supported by the distal end support portion 59 of the slave unit 9B (see FIG. 10C). From this state, when the electric motor M2 is rotationally driven to start the disengagement operation, the slide chuck device 30 moves back beyond the installation position of the auxiliary guide 31 to the takeover setting position P3, and the distal end portion 1F is moved to the slave unit. When a predetermined amount is projected to the 9A side, the rotation operation of the electric motor M2 is stopped and the slide chuck device 30 is stopped to temporarily stop the detachment operation (see FIG. 10B). Then, by raising the support portion 55T in the auxiliary guide 31 to the support position and supporting the intermediate portion of the support rod 1, the root portion 1N is supported by the slide chuck device 30 of the parent device 9A, and the auxiliary guide 31 of the parent device 9A. The intermediate portion of the support bar 1 is supported by the support portion 55T. Then, the electric motor M2 is rotationally driven again to restart the slide chuck device 30 so as to move back to the clamping body operation position P2 set in front of the backward limit P1 (see FIG. 10A). Note that the distal end support portion 59 of the slave unit 9B returns to the original position after the slide chuck device 30 resumes retreating.

  In this way, the support rod inserting / removing device 9 is a device for both insertion and removal that can automatically perform both the insertion and removal operations of the support rod 1 with this single unit. Moreover, when the support rod 1 is inserted and removed by the support rod insertion / removal device 9, the support rod 1 is driven by the slide chuck device 30 and the auxiliary guide 31 or the tip support portion 59 of the slave unit 9B at the root portion 1N. And it is supported by other places (for example, front-end | tip part 1F) away from the base part 1N, and can maintain a horizontal state. This prevents the support bar 1 from coming into contact with the inner surface of the support bar insertion hole of the roll-shaped article A so that dust is not generated.

  Since the roll-shaped article A has a long lateral width, the tip 1F of the support bar 1 is still in the roll-shaped article even when the slide chuck device 30 holding the base 1N of the support bar 1 is positioned at the setting position P3 for taking over. In order to cope with the case where the projection does not protrude from the hollow shaft core of A, the tip support portion 59 of the slave unit 9B is configured to be small enough to enter the hollow shaft core of the roll-shaped product A, and the roll-shaped product A The front end portion 1F of the support rod 1 may be supported by the front end support portion 59 in the hollow shaft core.

The front end portion and the rear end portion of the operation shaft 77 can be lifted and lowered in a balanced manner.

  An electric motor M4 with a gear for operating the lifting link is provided on the upper portion of the fixing member 71. When the crankshaft 73 is rotationally driven by the electric motor M4 for lifting link operation, the lifting link mechanism 65 is lowered. It operates between the dead center and the top dead center, and as a result, the elevating body 64 is reciprocated up and down between the ascending limit position and the descending limit position.

  When the support bar 1 separated by the support bar insertion / removal device 9 is received by the support bar receiver 63 when the elevating link mechanism 65 is located at the top dead center, and when the elevating link mechanism 65 is located at the top dead center The support rod 1 received and supported by the support rod receiver 63 is transferred to the support rod insertion / removal device 9.

  The connection height of the side frame 83 on the side where the support bar receiving rail 86 protrudes is lower than the connection height of the side frame 83 on the side where the support bar reception rail 86 does not protrude, and the upper shelf assembly 79U is The support rod receiving rail 86 is attached so as to be inclined downward from the side from which the support rod receiving rail 86 protrudes toward the side from which the support rod receiving rail 86 does not protrude. Accordingly, as shown in FIGS. 11A and 11B, the upper shelf assembly 79 </ b> U is configured so that the support bar 1 received at the transfer position Psr is placed and supported on the support bar support rail 86. Along the downward inclined surface Su formed on the upper surface (hereinafter referred to as the upper inclined conveying surface Su), it can roll to the inter-shelf relay device 80 side by its own weight.

  In the lower shelf assembly 79D, a support bar receiving rail 86 protrudes from the middle height portion of each of the right front vertical frame 78RF and the right rear vertical frame 78RB arranged forward and backward on the right side (the lifting unit 10E side) of the main body frame 78. A pair of front and rear front side horizontal frames that are connected to the front and rear ends of the non-side side frame 83 and that are provided substantially horizontally along the left-right direction at the intermediate height of the front and rear surfaces of the main body frame 78. The front and rear ends of the side frame 83 on the side from which the support rod receiving rail 86 protrudes are connected to the 78FSM and the rear intermediate horizontal frame 78BSM.

  The connection height of the side frame 83 on the side where the support rod receiving rail 86 does not protrude is lower than the connection height of the side frame 83 on the side where the support rod reception rail 86 protrudes, and the lower shelf assembly 79D is The support rod receiving rail 86 is attached so as to be inclined downward from the side from which the support rod receiving rail 86 protrudes toward the side from which the support rod receiving rail 86 does not protrude. Accordingly, as shown in FIG. 11C, the lower shelf assembly 79 </ b> D is placed on the upper surface of the support bar receiving rail 86 while the support bar 1 received from the inter-shelf relay device 80 is placed and supported on the support bar receiving rail 86. Along the downwardly inclined surface Sd (hereinafter, referred to as a lower inclined conveying surface Sd) formed by rolling, it can roll to the lifting unit 10E side by its own weight.

  The upper shelf assembly 79U and the lower shelf assembly 79D are provided with the downstream stopper SP3 provided at the protruding position, so that the upper shelf conveyance surface Su of the upper shelf assembly 79U and the lower shelf conveyance surface of the lower shelf assembly 79D. A plurality of support rods 1 can be stored in a state of being aligned along the inclination direction of Sd.

  The inter-shelf relay device 80 is installed on the left side of the main body frame 78 at a position facing the lifting unit 10E. The receiving position when the pair of front and rear support bar receivers 94 of the inter-shelf relay device 80 are located on the virtual extension line of the support bar receiving rail 86 of the upper shelf assembly 79U, and the side of the support bar receiving rail 86 of the lower shelf assembly 79D It is configured to be moved up and down between a supply position located at an end protruding from the frame 83.

  Since the inter-shelf relay device 80 is partially configured in the same manner as the lifting body 64 so as to be shared with the lifting body 64 of the lifting unit 10E, detailed description of the device configuration is omitted. In the elevating unit 10E, the elevating link mechanism 65 is swung between the top dead center and the bottom dead center to raise and lower the support bar receiver 63. However, in the inter-shelf relay device 80, the support bar is supported by a gas spring. The receiver 94 is configured to move up and down.

  That is, the support bar receiver 94 is provided in a state of being biased back to the receiving position by the gas spring. When the support bar 1 is not placed on the support bar receiver 94, the holding bar receiver 94 is at the receiving position. When the support bar 1 is placed on the support bar receiver 94, the gas spring is degenerated by the weight of the support bar 1, and the holding bar receiver 94 is lowered to the supply position.

  Accordingly, as shown in FIG. 11, if the support bar receiver 94 of the inter-shelf relay device 80 is positioned at the receiving position, the upper inclined transport surface Su formed by the support bar support rail 86 of the upper shelf assembly 79U. After the support rod 1 rolling along is received and supported by the recessed portion of the support rod receiver 94, the support rod receiver 94 is lowered by its own weight. Then, after the lower end portion of the support bar 1 comes into contact with the support bar receiving rail 86 of the lower shelf assembly 79D, the support bar receiver 94 continues to descend due to inertia, and the support bar 1 moves from the recessed portion of the support bar receiver 94. The support rod receiving rail 86 of the lower shelf assembly 79D is taken over, and the support rod 1 rolls along the lower inclined conveying surface Sd formed by the support rod receiving rail 86 of the lower shelf assembly 79D, and the support rod receiver 94 is moved. Rises back to the receiving position.

  In addition, when the support rod 1 is continuously delivered to the support rod insertion / removal device 9 and the support rod 1 stored in the support rod storage device 10 is insufficient, an inter-shelf relay device is provided by an operator. A new support bar 1 is supplied on the support bar receiving rail 86 of the lower shelf assembly 79D with the 80 support bar receivers 94 positioned at the receiving position.

  In the space of the base 29 located on the right side of the lower shelf assembly 79D, a pair of front and rear swing relay rails 82 that form a relay transport surface Sc extending from the downstream end portion of the lower inclined transport surface Sd to the preparation position Pj. Is attached to the base 29. The swinging relay rail 82 has a relay posture in which the longitudinal direction thereof coincides with the virtual extension line of the support bar receiving rail 86 of the lower shelf assembly 79D to form the relay transport surface Sc, and the end of the lower shelf assembly 79D is the collection tray. It is attached so as to be swingable around the horizontal axis set on the base 29 side between the discharge posture positioned on the 81 side.

  The swing relay rail 82 is elastically biased to a relay position by a biasing coil spring (not shown). The main body frame 78 has a lock state in which the swing relay rail 82 is fixed in the relay position, and a discharge state. A lock mechanism (not shown) that can be switched to a release state that allows swinging to the posture is provided. The lock mechanism is normally locked, and when the storage number N of the support rods 1 stored in the storage unit 10B reaches the storage allowable upper limit number Nmax, the operation of an actuator such as an electric cylinder is activated. Switched to the released state.

  The lock mechanism is controlled by the storage controller H3 by controlling the operation of the actuator of the lock mechanism in accordance with the storage number N of the support rods 1 stored on the upper inclined conveyance surface Su and the lower inclined conveyance surface Sd. Is done. In other words, the number of the support bars 1 stored in the storage unit 10B is managed by the storage number management process as the storage number management means Hn executed by the storage device controller H3. That is, the storage device controller H3 performs the number of times of receiving control executed when receiving the support rod 1 from the support rod insertion / removal device 9 and the support rod 1 with respect to the support rod insertion / removal device 9 in the storage number management process. The storage number N of the support rods 1 is managed based on the number of times delivery control executed when delivering is performed. When the storage number N exceeds the storage allowable upper limit number Nmax, the storage device controller H3 operates an actuator such as an electric cylinder to switch the lock mechanism to the released state. In the storage number management process, when the support bar 1 is ejected as will be described later, the storage number N is decremented by 1 separately from the process based on the number of times the delivery control is executed.

  When the lock mechanism is switched to the locked state, as shown in FIG. 11 (c), the support rod 1 that has rolled along the lower inclined conveying surface Sd is transferred to the swing relay rail 82 and relayed as it is. It rolls to the preparation position Pj along the relay conveyance surface Sc formed by the swinging relay rail 82 in the posture, and is received and supported by the lifting body 64 of the lifting unit 10E located at the lower limit position.

  When the lock mechanism is switched to the released state, when the support bar 1 that has rolled along the lower inclined conveyance surface Sd rolls to the swing relay rail 82 and is transferred, the support bar 1 swings due to its own weight. The relay rail 82 swings to the discharge posture side, and the inclination direction of the swing relay rail 82 is reversed. As a result, the support rod 1 rolls in the reverse direction from the middle portion of the swing relay rail 82 to prepare. The paper is discharged to the collection tray 81 without reaching the position Pj. When the load by the support rod 1 on the swing relay rail 82 is removed, the swing relay rail 82 swings back to the relay posture by the biasing force.

  As described above, the storage unit 10B can receive the support bar 1 at the transfer position Psr by the support bar receiver 63 of the elevating unit 10E, and can transport the received support bar 1 to the preparation position Pj via the swing relay rail 82. It is like that. Therefore, the storage unit 10B functions as a storage unit of the present invention.

  In addition, the storage unit 10B includes a support bar receiving rail 86 for the upper shelf assembly 79U, a slide table 89, a support bar receiving rail 86 for the lower shelf assembly 79D, and a swing relay rail as an inclined portion where the support bar 1 rolls. 82, the support bar 1 received at the transfer position Psr is configured to be movable along these members to the preparation position Pj, and the support bar support rail 86 and the lower shelf of the upper shelf assembly 79U as an inclined portion. The support rod 1 is configured to be stored in the support rod receiving rail 86 of the assembly 779D.

  As shown in FIG. 12, the lifting device controller H1, the support rod insertion / removal controller H2, and the storage device controller H3 are connected so as to be able to communicate in a comprehensive manner, and the lifting device 8, the support rod insertion / removal device 9 and the support are connected. The operation of the bar storage device 10 is controlled in cooperation. Below, among the control operations by the cooperation of these controllers, the operation in the receiving control from when the support rod 1 is detached by the support rod insertion / removal device 9 until it is received by the support rod storage device 10, and the support rod storage Only the operation in the delivery control until the support rod 1 stored in the device 10 is delivered to the support rod insertion / removal device 9 will be briefly described based on the flowcharts shown in FIGS.

  In the standby state until the support bar storage device 10 receives and transfers the support bar 1, the support bar receiver 63 of the elevating unit 10E is located at the preparation position Pj, and the upper shelf assembly 79U in the storage unit 10B. Slide table 89 is located at the retracted position, the downstream stopper SP3 of the upper shelf assembly 79U and the lower shelf assembly 79D is located at the protruding position, and the locking mechanism is in the locked state.

  As described above, when the ride chuck device 30 is retracted to the holding body operation position P2 by the operation of removing the support rod 1, the operation of removing the support rod 1 by the support rod insertion / removal device 9 is completed, and the support rod insertion / removal controller is completed. H2 outputs a support bar removal completion signal to the storage device controller H3. As a result, reception control is started. In the receiving control, as shown in FIG. 13, the storage device controller H3 raises the support rod receiver 63 of the elevating unit 10E to the ascending limit position in step # R1 (hereinafter abbreviated as “step”). After that, the support rod insertion / removal controller H2 opens the pair of sandwiching bodies 48 of the slide chuck device 30 to the separation position at # R2, and the support portion 55T of the auxiliary guide 31 at the support position to the standby position at # R3 Lower. By synchronizing the lowering operation of the lower clamping body 48 and the support portion 55T, the support bar 1 is lowered while maintaining the horizontal state. Thus, as the support bar 1 is lowered while maintaining the horizontal state, the support bar 1 is transferred to the pair of front and rear support bar receivers 63 located at the upper limit position.

  When the processes of # R2 and # R3 are completed, the support rod insertion / removal controller H2 retracts the slide chuck device 30 to the retreat limit P1 at # R4. Then, before the processing of # R2 to # R4 is completed, the storage device controller H3 causes the pair of front and rear slide tables 89 to project obliquely upward to the receiving position at # R5. As a result, the pair of front and rear slide tables 89 inclined to the upper shelf assembly 79U side of the storage unit 10B is moved downward when the support bar 1 at the transfer position Psr is lowered below the front and rear sides of the pair of front and rear support bar receivers 63. It will be in a state where it can be received.

  In # R6, the storage device controller H3 lowers the support bar receiver 63 of the elevating unit 10E from the ascent limit position to the descent limit position. As a result, the support bar 1 positioned at the transfer position Psr is lowered and received and supported by the pair of front and rear slide tables 89, along the upper inclined conveyance surface Su formed by the slide table 89 and the support bar receiver 63. And is received by the upstream stopper SP1 of the upper end shelf assembly 79U (see FIG. 11A). After the support bar 1 is thus inherited by the storage unit 10B, the storage device controller H3 retracts the slide table 89 to the retracted position.

  Next, delivery control will be described. The delivery control is started when a support bar request signal is output from the support bar insertion / removal device controller H2 to the storage device controller H3. In the delivery control, as shown in FIG. 14, in # S1, the storage device controller H3 lowers the downstream stopper SP3 of the lower shelf assembly 79D to the retracted position and rolls the support rod 1 to be delivered to the preparation position Pj. (Refer FIG.11 (c)). For example, if the slide chuck device 30 is not positioned at the retreat limit P1 immediately after the preceding operation of inserting the support rod 1 is completed, the support rod insertion / removal device controller H2 determines that the slide chuck device 30 is # S2. The device 30 is retracted to the retract limit P1. Thereafter, in # S3, the storage device controller H3 raises the support bar receiver 63 of the elevating unit 10E located at the lower limit position to the upper limit position, and raises the support bar 1 from the preparation position Pj to the transfer position Psr.

  Then, the support rod insertion / removal device controller H2 advances the slide chuck device 30 to the clamping body operating position P2 in # S4, and then closes the pair of clamping bodies 48 of the slide chuck device 30 to the approach position in # S5. While operating, the support part 55T of the auxiliary guide 31 is raised to a support position by # S6 (refer Fig.10 (a)). As a result, the support bar 1 positioned at the transfer position Psr is transferred to the support bar insertion / removal device 10. Note that the raising operation of the auxiliary guide 31 is set to start earlier than the closing operation of the holding body 48 so that the lower holding body 48 and the support portion 55T come into contact with the support rod almost simultaneously. .

  When the processes of # S5 and # S6 are completed, the storage device controller H3 lowers the support bar receiver 63 of the elevating unit 10E located at the ascending limit position to the descending limit position at # S7. When the delivery control is thus completed, the support rod insertion / removal device controller H2 advances the slide chuck device 30 to insert the support rod 1 into the roll-shaped article A, and the insertion operation (see FIG. 10) is started.
