Description

  The present invention relates to a laying / collecting device used when laying or collecting a long material such as a fire hose or a cable.

  Conventionally, when a long material such as a fire hose is laid, the long material wound around the reel is often manually laid out. However, when a long material is laid over a long distance, the labor becomes large, and the laying work takes a considerable amount of time. Therefore, an apparatus that can more easily lay and collect a fire hose has been proposed (see, for example, Patent Document 1). This laying / collecting device includes a reel rotatably supported on a self-propelled vehicle around a support shaft, and a drive roller that rotationally drives the reel. The reel is rotated so that the fire hose can be fed out (or wound up).

  Further, the laying / collecting device is provided with a winch for exchanging reels. The winch lifts or lowers the reel along an inclined arm extending downward and rearward from the position of the bearing of the support shaft by winding or unwinding the wire connected to the support shaft of the reel with this winch. Can be exchanged.

  A first embodiment of the present invention will be described. This first embodiment applies the present invention to a laying / collecting device for laying / collecting a long and large-diameter fire hose, which is particularly used when performing fire extinguishing activities at a site having a large site area such as a complex. This is an example. In the following description, the left side in FIG. 1 is defined as the front, and the vertical direction in FIG. 1 is defined as the left-right direction.

  As shown in FIGS. 1 to 3, the laying / collecting device 1 according to the first embodiment can rotatably support a reel 3 around which a fire hose 2 is wound, and includes two drive wheels 20 and two slaves. A carriage 10 provided with a driving wheel 21, traveling drive motors 22 and 23 (traveling drive means) for driving the two drive wheels 20, respectively, and a rotation drive motor 24 for rotating the reel 3 (rotation drive means: see FIG. 4). Control of the entire laying / collecting device 1 including the generator 12 that generates electric power consumed by the travel drive motors 22 and 23 and the rotation drive motor 24, and the travel drive motors 22 and 23 and the rotation drive motor 24. A control device 13 is provided. In FIG. 2, the generator 12 and the control device 13 are not shown so that the internal configuration of the laying / collecting device 1 can be easily understood.

  The laying / collecting device 1 according to the first embodiment is configured to lay or collect the fire hose 2 by rotating the reel 3 while the cart 10 is self-propelled. Therefore, the laying / collecting device 1 is particularly suitable for laying or collecting a hose having a relatively large diameter and a large weight (for example, a diameter of 400 mm, a width of about 60 cm, and a length of about 200 m). Yes.

  The carriage 10 includes a horizontal frame 14 and a vertical frame 15 provided at the rear end of the horizontal frame 14, and has a solid structure that can sufficiently withstand the weight of the reel 3. Further, the horizontal frame 14 includes two side portions 14a arranged on both sides in the traveling direction (front-rear direction), and a horizontal connecting portion 14b that connects the rear end portions of the two side portions 14a. A vertical frame 15 is erected on the upper surface of the connecting portion 14 b of the horizontal frame 14.

  Two drive wheels 20 are rotatably provided on the left and right sides of the connecting portion 14b of the horizontal frame 14, respectively. As shown in FIG. 2, the output shafts of two travel drive motors 22 and 23 supported by bearings 25 are directly connected to these two drive wheels 20, respectively. The motors 22 and 23 are respectively driven to rotate. In this way, the traveling drive motors 22 and 23 are independently coupled to the drive wheels 20, so that the traveling drive motors 22 and 23 are independent by a traveling direction changing unit 61 (see FIG. 4) of the control device 13 described later. Thus, the traveling direction of the carriage 10 can be changed by making the rotational speeds of the two drive wheels 20 different from each other. On the other hand, two driven wheels 21 are rotatably provided on the left and right sides of the front end portion of the two side portions 14a of the horizontal frame 14, respectively. The traveling speed and traveling direction of the carriage 10 can be arbitrarily set by the remote controller 65 (see FIG. 4).

  As shown in FIG. 2, the two side portions 14a are connected to each other via a connecting portion 14b only at their rear end portions with a space wider than the width of the reel 3, and these two side portions 14a. The space between is open forward. Therefore, the reel 3 can be taken in and out between the two side portions 14a from the front.

  By the way, two pivotal support members 26 each having a rectangular plate shape extending in the vertical direction are fixed to middle portions in the front-rear direction of the two side portions 14a. Further, a middle portion in the length direction of a substantially rectangular plate-like link member 27 is pivotally connected to the upper end portion of each pivot member 26 so as to be rotatable. On the other hand, as shown in FIG. 2, a central hole 3 a that penetrates the reel 3 in the width direction (left-right direction) is formed at the center of the reel 3. In addition, two rotary shaft portions 28 are connected to the tip portions of the left and right link members 27 in a penetrating manner, and these two rotary shaft portions 28 are reels disposed between the two side portions 14a. 3 is inserted into the center hole 3a. That is, the two rotating shaft portions 28 inserted into the center hole 3 a of the reel 3 are supported by the two side portions 14 a via the link member 27 and the pivot member 26, respectively.

  Further, two hydraulic cylinders 29 (vertical drive means) for driving the reel 3 up and down via the link member 27 are provided on the two side portions 14a. Each hydraulic cylinder 29 has a cylinder body 30 rotatably attached to a bracket 33 fixed to the upper surface of the side portion 14a, and a rod 31 provided in the cylinder body 30 so as to be able to advance and retract. The cylinder body 30 of each hydraulic cylinder 29 is connected to a hydraulic pressure supply source 32 (see FIG. 4) configured by a hydraulic pump, a switching valve, and the like, and the rod 31 is driven to advance and retract by the hydraulic pressure supplied from the hydraulic pressure supply source 32. It is configured to be. The tip of the rod 31 is connected to the rear end of the link member 27. Therefore, as shown in FIG. 1, when the rod 31 is retracted to the maximum extent, the reel 3 is lifted upward via the link member 27, and the reel 3 is separated from the running surface 100 and left and right rotating shafts. It will be in the state supported by the part 28 so that rotation was possible. On the other hand, as shown in FIG. 3, when the rod 31 has advanced to the maximum extent, the reel 3 is lowered and contacts the running surface 100. Therefore, in this state, when the two rotation shaft portions 28 are further extracted from the center hole 3a of the reel 3 and the pivot support state of the reel 3 by the rotation shaft portion 28 is released, the reel 3 is attached to the two side portions 14a. Can be taken forward from between.

  Further, the laying / collecting device 1 is configured so that the driving force of the hydraulic cylinder 29 is transmitted to the two rotary shaft portions 28 via the link member 27 pivotally supported by the pivot member 26 so that the reel 3 moves up and down. Although configured, according to this configuration, the stroke of the rod 31 can be reduced compared to a configuration in which the reel 3 is moved up and down directly by the hydraulic cylinder 29, and the apparatus can be downsized accordingly. become.

  A handle 34 is provided at the outer end of each rotary shaft 28 so that the rotary shaft 28 can be easily inserted into the center hole 3 a of the reel 3. As shown in FIG. 2, the insertion length L of the rotary shaft portion 28 inserted into the center hole 3 a is shorter than half of the width B of the reel 3. Therefore, compared with the case where one long shaft member serving as a rotation shaft is inserted through the entire width of the reel 3 into the center hole 3a of the reel 3, the insertion operation is facilitated, and the rotation shaft portion 28 is provided. The surrounding space necessary for taking in and out is small.

  As shown in FIGS. 1 to 3, the rotation shaft portion 28 on the left side (the front side in FIG. 1) is a chain provided inside the link member 27 and the pivot member 26 corresponding to the rotation shaft portion 28. The rotary drive motor 24 (see FIG. 4) is connected to the rotary drive motors 35, 36 and sprockets 37, 38, 39, and the like. Therefore, the driving force of the rotary drive motor 24 is transmitted to the left rotating shaft portion 28 via the chains 35, 36 and the sprockets 37, 38, 39, and is pivotally supported by the left and right rotating shaft portions 28 by this driving force. The reel 3 is rotated. The rotation speed of the reel 3 can be arbitrarily set by the remote controller 65 (see FIG. 4).

  A generator 12 and a control device 13 are disposed on the upper side of the connecting portion 14b of the carriage 10. Various signals relating to various operations of the laying / collecting device 1 such as the traveling operation of the carriage 10 and the rotation operation of the reel 3 are input to the control device 13 from the remote controller 65 (see FIG. 4). The operation of the control device 13 will be described in detail later. Further, the generator 12 is configured to generate electric power required by the travel drive motors 22, 23, the rotation drive motor 24, and the like based on a command from the control device 13.

  Further, as shown in FIGS. 1 to 3, the vertical frame 15 of the carriage 10 is wound around the reel 3 in order to smoothly feed out the fire hose 2 from the reel 3 and wind it up with the reel 3. There is provided a traverse mechanism 16 (traverse means) for reciprocating the portion of the fire hose 2 that is not reciprocated relative to the carriage 10 in the left-right direction (direction parallel to the rotation shaft portion 28 that is the rotation shaft of the reel 3). ing. The traverse mechanism 16 has a movable frame 50 that can move in the left-right direction with respect to the vertical frame 15, a drive motor 51 (see FIG. 4) that moves the movable frame 50 in the left-right direction, and a movable frame 50 that can rotate freely. A feed roller 52 is provided.

  As shown in FIG. 2, the moving frame 50 has a structure in which two left and right plate members 55 and 56 are connected to each other with an interval wider than the width of the fire hose 2 wound around the reel 3. The plate members 55 and 56 of the moving frame 50 are integrally formed with cylindrical portions 55a and 56a that protrude inward and have screw portions inside, respectively. On the other hand, a screw shaft 57 extending in the left-right direction is rotatably provided at the upper end portion of the vertical frame 15, and a guide shaft 58 is also provided below the screw shaft 57. The cylindrical portions 55a and 56a of the moving frame 50 are threadedly engaged with the screw shaft 57, and the screw shaft 57 is connected to the drive motor 51, although not shown. Further, a guide shaft 58 is inserted into the plate members 55 and 56 of the moving frame 50.

  The feed roller 52 is rotatably provided between the left and right plate members 55 and 56 of the moving frame 50. Further, two guide rollers 59 extending in the vertical direction are rotatably provided at positions near the both ends of the feed roller 52 of the moving frame 50. Accordingly, the fire hose 2 fed out from the reel 3 or wound around the reel 3 is fed in the front-rear direction by the feed roller 52 between the two guide rollers 59.

When the fire hose 2 is unwound from the reel 3 or when the fire hose 2 is wound around the reel 3, the screw shaft 57 is rotationally driven by the drive motor 51, and the screw shaft 57 is rotated. The moving frame 50 reciprocates left and right while being guided by the guide shaft 58. The portion of the fire hose 2 sent by the feed roller 52 between the two guide rollers 59 is fed out from the reel 3 while moving left and right in synchronization with the rotation of the reel 3, or is wound around the reel 3. Therefore, the fire hose 2 can be prevented from being entangled or twisted.
When the fire hose 2 is collected, the position of the moving frame 50 is as high as possible in order to make it easier to drain water from the connecting portion 2a of the fire hose 2 when the fire hose 2 is fully wound on the reel 3. Preferably it is in position.

  In addition, a feed roller 45 is rotatably provided at a position obliquely below and below the traverse mechanism 16. Therefore, since the fire hose 2 sent backward from the traverse mechanism 16 is further laid on the traveling surface 100 while being sent by the feed roller 45, the fire hose 2 is more likely to get entangled or twisted. It can be surely prevented.

  In addition, as shown in FIGS. 1 to 3, a brush 40 having a large number of bristles whose tips are in contact with the running surface 100 at the center in the left-right direction of the rear end portion of the carriage 10 (connection portion 14 b) The brush 40 is rotationally driven by a brush drive motor 41 (see FIG. 4). Then, when the carriage 10 is caused to travel with the brush 40 rotating, an object such as a stone existing on the traveling surface 100 is jumped off immediately before the fire hose 2 is laid on the traveling surface 100. Since the fire hose 2 is excluded from the laying path, it is possible to prevent the fire hose 2 from being laid on an object such as a stone. In addition, since the fire hose 2 can be laid by running the carriage 10 while removing stones and the like with the brush 40, it is not necessary to remove stones and the like before laying the fire hose 2 and the laying work is further performed. Can be done quickly.

Next, the electrical configuration of the laying / collecting device 1 centering on the control device 13 will be described with reference to the block diagram of FIG.
The control device 13 includes a central processing unit (CPU), a ROM (Read Only Memory) storing various programs and data for controlling the overall operation of the laying / collecting device 1, and a CPU. A RAM (Random Access Memory) or the like for temporarily storing data to be processed is provided.

  The control device 13 includes a traveling speed adjusting unit 60 that adjusts the traveling speed of the carriage 10, a traveling direction changing unit 61 that changes the traveling direction of the carriage 10, a rotational speed adjusting unit 62 that adjusts the rotational speed of the reel 3, A traverse control unit 63 that controls the traverse mechanism 16 (traverse drive motor 51). The travel speed adjustment unit 60, the travel direction change unit 61, the rotation speed adjustment unit 62, and the traverse control unit 63 are configured by a CPU, a ROM, a RAM, and the like in the control device 13.

  From the remote controller 65, the control device 13 receives a start / stop signal for the carriage 10, a setting signal for the traveling speed of the carriage 10, a setting signal for the traveling direction of the carriage 10, a rotation start / stop signal for the reel 3, or Various signals such as a setting signal for the rotation speed of the reel 3 are input. Further, the control device 13 outputs various control signals such as start / stop signals to the drive motors 22, 23, 24, 41, 51, the hydraulic supply source 32, the generator 12, and the like.

  The traveling speed adjusting unit 60 controls the rotational speeds of the two traveling drive motors 22 and 23 so that the traveling speed of the carriage 10 becomes a predetermined speed set by the remote controller 65. Further, the traveling direction changing unit 61 rotates the rotational speeds of the two traveling drive motors 22 and 23 (that is, the two driving wheels 20) so that the traveling direction of the carriage 10 becomes a predetermined traveling direction set by the remote controller 65. And the direction of the carriage 10 is changed according to the difference in the rotational speed. Specifically, when the remote controller 65 gives an instruction to change the traveling direction of the carriage 10 to the right, the traveling direction changing unit 61 drives the driving on the left side of the rotational speed of the right traveling driving motor 23. The rotational speed of the motor 22 is increased. Conversely, when an instruction to change the traveling direction of the carriage 10 to the left is given, the traveling direction changing unit 61 sets the rotational speed of the right traveling drive motor 23 to be higher than the rotational speed of the left traveling drive motor 2. Enlarge. Here, the steep change in the instructed traveling direction (that is, the greater the turning angle of the carriage 10), the greater the difference in rotational speed between the two traveling drive motors 22 and 23.

  The rotation speed adjustment unit 62 adjusts the rotation speed of the rotation drive motor 24 (that is, the feeding speed of the fire hose 2 or the fire hose 2 so that the rotation speed of the reel 3 becomes a predetermined speed set by the remote controller 65. The winding speed). The traverse control unit 63 controls the traverse drive motor 51 so that the moving frame 50 of the traverse mechanism 16 reciprocates left and right in synchronization with the rotation of the reel 3 adjusted by the rotation speed adjusting unit 62.

  Next, the operation of laying and collecting the fire hose 2 of the fire hose 2 laying / collecting device 1 will be described. In the first embodiment, one fire hose 2 wound around one reel 3 has a relatively large diameter and a large weight (for example, a diameter of 400 mm, a width of about 60 cm, and a length of about 200 m). ). Then, a plurality of fire hoses 2 wound around the reels 3 are sequentially laid while exchanging the plurality of reels 3, and the fire fighting hoses 2 are connected to each other at the connection portion 2a, thereby The hose 2 is laid over a long distance.

  First, the reel 3 around which the fire hose 2 is wound is attached to the carriage 10 according to the following procedure. First, the reel 3 is rolled and moved from the front with respect to the stopped carriage 10, or the driving wheel 20 is driven to rotate by the traveling drive motors 22 and 23 so that the carriage 10 travels forward, whereby the reel 3 is moved to the carriage. The reel 3 is inserted between the two side portions 14 a from the front end side portion of the carriage 10. Next, as shown in FIG. 3, the two rotating shaft portions 28 penetrating the left and right link members 27 are respectively inserted into the center hole 3a of the reel 3 disposed between the two side portions 14a from both the left and right sides. To do. Then, when hydraulic pressure is supplied from the hydraulic supply source 32 to the left and right hydraulic cylinders 29 and the rod 31 of the hydraulic cylinder 29 is retracted to the maximum, the reel 3 is moved upward via the link member 27 as shown in FIG. As a result, the reel 3 is separated from the running surface 100 and is pivotally supported by the two left and right rotating shafts 28.

  In this state, when the traveling speed of the carriage 10 is set from the remote controller 65 and the start of the carriage 10 is instructed, the two traveling drive motors 22 and 23 are activated and the carriage 10 starts to travel, and the control device The two travel drive motors 22 and 23 are controlled by the 13 travel speed adjusting units 60, and the carriage 10 travels at the set travel speed. Here, the traveling speed of the carriage 10 is set to a speed substantially equal to the walking speed of the worker so that the worker can operate the remote controller 65 while walking near the traveling carriage 10.

  When an instruction to change the traveling direction of the carriage 10 is given from the remote controller 65, the two traveling drive motors 22 and 23 are controlled by the traveling direction changing unit 61 of the control device 13 so that their rotational speeds are different from each other. A difference in rotational speed between the two drive wheels 20 is generated, the carriage 10 bends in the direction set by the remote controller 65, and the traveling direction is changed.

  When the rotation speed of the reel 3 is set from the remote controller 65 and an instruction to start the rotation of the reel 3 is given, the rotation drive motor 24 is activated to start the rotation of the reel 3, and the rotation speed of the control device 13 is adjusted. The rotary drive motor 24 is controlled by the unit 62, the reel 3 rotates at the set rotation speed, and the fire hose 2 is fed out from the reel 3. At this time, the traverse control motor 63 of the control device 13 controls the traverse drive motor 51, and the moving frame 50 of the traverse mechanism 16 reciprocates left and right in synchronization with the rotation of the reel 3. Therefore, the feed roller 52 and the two guide rollers 59 are located at a position where the fire hose 2 is sent substantially straight rearward, and the fire hose 2 is removed from the reel 3 through the feed roller 52 and the guide roller 59. It goes out smoothly.

  Further, during this laying operation, when an instruction to drive the brush 40 is given from the remote controller 65, the brush 40 is rotationally driven by the brush drive motor 41. When the carriage 10 travels while the brush 40 is rotating, an object such as a stone existing on the traveling surface 100 is jumped off immediately before the fire hose 2 is laid (contacted) on the traveling surface 100. Therefore, the fire hose 2 is not laid on the object such as stone. In addition, since the fire hose 2 can be laid by running the carriage 10 while removing stones and the like with the brush 40, it is not necessary to remove stones and the like before laying the fire hose 2 and the laying work is further performed. Can be done quickly.

  When all the fire hoses 2 wound on the reel 3 are laid, the reel 3 is replaced as follows. First, as shown in FIG. 3, the rod 31 of the hydraulic cylinder 29 is advanced as much as possible, the link member 27 is rotated, the reel 3 is lowered, and the reel 3 is brought into contact (placed) with the running surface 100. From this state, two more rotating shaft portions 28 are removed from the reel 3 to release the pivoting state of the reel 3 by the rotating shaft portion 28, and then the empty reel 3 is taken forward from between the two side portions 14a. Instead, the reel 3 is replaced by moving another reel 3 around which the fire hose 2 is wound between the two side portions 14a. According to this replacement procedure, the reel 3 can be easily replaced and the replacement work can be performed quickly. Therefore, it is necessary to lay the fire hose 2 over a long distance in a fire site having a large site area such as a complex. Even in this case, the laying operation can be completed in a short time.

  With regard to the replacement of the reel 3, a plurality of reels 3 are stored in a predetermined storage location, and each time the reel 3 is replaced, the carriage 10 is moved to the storage location to perform the replacement operation of the reel 3. However, when a fire breaks out, a plurality of reels 3 are arranged at a predetermined distance on a route where the fire hose 2 is laid, and the reels are emptied in the middle of the laying route. The reel 3 may be replaced with another reel 3. In this case, it is not necessary to reciprocate the carriage 10 between the storage place and the laying route every time the reel 3 is replaced.

  On the other hand, when the fire hose 2 laid on the traveling surface 100 is collected by the laying / collecting device 1, the empty reel 3 is attached to the carriage 10, and then the traveling speed of the carriage 10 and the carriage 10 are controlled from the remote controller 65. The travel direction and the rotation speed of the reel 3 are set. Then, while the traveling speed adjusting unit 60 and the traveling direction changing unit 61 control the two traveling drive motors 22 and 23 to travel the carriage 10, the rotational speed adjusting unit 62 controls the rotational drive motor 24 and The fire hose 2 is wound up by rotating the reel 3 at a rotational speed set in a direction opposite to that at the time of laying. As the winding operation proceeds, when the fire hose 2 can no longer be wound on a certain reel 3, the reel 3 is replaced with another empty reel 3 and the collecting operation is resumed. .

  According to the laying / recovering device 1 described above, the reel 3 is driven downward by the hydraulic cylinder 29 between the two side portions 14 a in contact with the traveling surface 100 while the reel 3 is attached to the carriage 10. Then, after the two rotary shafts 28 are removed from the reel 3, the reel 3 is moved relative to the carriage 10 in the traveling direction (front-rear direction), so that the two side portions 14a are not connected to each other. The reel 3 can be easily taken out from. Conversely, with the reel 3 not attached to the carriage 10, the reel 3 is disposed between the two side portions 14 a from the front, and then the reel 3 is driven upward by the hydraulic cylinder 29 to run the reel 3. By separating from the surface 100, the reel 3 can be easily installed on the carriage 10. Accordingly, the reel 3 can be easily replaced, and in particular, even when the large-diameter and long fire hose 2 is wound and the reel 3 is heavy, the fire hose 2 can be laid quickly. Become.

The rod 31 of the hydraulic cylinder 29 may be connected to the rotary shaft portion 28 without the link member 27, and the reel 3 may be directly driven up and down by the hydraulic cylinder 29. Further, as a vertical driving means for driving the reel 3 up and down, a motor, a screw mechanism or the like may be used instead of the hydraulic cylinder 29.

  5] In the first embodiment, the reel 3 is pivotally supported by the two left and right rotating shafts 28, but is configured to be pivotally supported by one shaft member that penetrates the reel 3. It may be.

  6] In the first embodiment, the brush 40 for removing an object such as a stone existing on the traveling surface is configured to be driven to rotate, but the brush is configured to be reciprocated in the left-right direction. Even if it is done, it is possible to remove objects such as stones. Furthermore, as means for removing an object such as a stone (inhibitor removal means), a means other than a brush can be employed. For example, as shown in FIG. 5, the laying / collecting device 1B includes a scraping portion 70 having an inverted L-shaped cross section that extends rearward from the carriage 10 and further extends downward from the rear end to the vicinity of the traveling surface 100. As the carriage 10 travels, the scraping unit 70 may scrape off an object present on the traveling surface 100.

Next, a second embodiment of the present invention will be described with reference to FIG. In the following description, the left side in FIG. 6 is defined as the front, and the vertical direction in FIG. 6 is defined as the left-right direction.
As shown in FIG. 6, the laying / collecting device 51 of the second embodiment includes two drive wheels 70 and two driven wheels 71, and has a carriage 60 that pivotally supports the reel 3. Similar to the first embodiment, the cart 60 of the second embodiment also includes two side portions 60a disposed on both sides in the traveling direction (front-rear direction), and one end portion (front end) of the two side portions 60a. Part) and a horizontal connecting part 60b for connecting each other. At the front end of the carriage 60 are provided two drive wheels 70 and a travel drive motor 72 that rotationally drives each of the drive wheels 70, while two driven wheels 71 are provided at the rear end of the carriage 60. The cart 60 is capable of traveling on the traveling surface 100.

  Further, a generator 73 that generates electric power consumed by the travel drive motor 72 and the like, and a control device (not shown) that controls the entire laying / collecting device 51 are disposed on the upper surface of the horizontal connecting portion 60b. Has been. Further, an arm 75 having one end connected to a shaft member 74 inserted through the center hole of the reel 3 is pivoted around the end opposite to the shaft member 74 at the rear end of the connecting portion 60b. It is attached as possible.

  Further, the laying / collecting device 51 rotates the reel 3 in a vertical plane, thereby causing the fire hose 2 wound around the reel 3 to have rollers 76, 77, 78, 79 disposed above the connecting portion 60b. In order to pay out forward or to wind up the fire hose 2 on the reel 3, the following structure is provided. A driving roller 80 extending in the left-right direction (the width direction of the reel 3: the direction perpendicular to the paper surface of FIG. 6) is rotatably provided at the rear end portion of the connecting portion 60b. Further, in the vicinity of the drive roller 80, a roller drive motor 82 (roller drive means) that rotationally drives the drive roller 80 is provided. Furthermore, a driven roller 81 extending in the left-right direction is provided on the two side portions 60a so as to be rotatable and straddle the two side portions 60a. Then, with the lower part of the reel 3 pivotally supported via the shaft member 74 in contact with the driving roller 80 and the driven roller 81, the driving roller 80 is rotated by the roller driving motor 82, whereby the reel 3 is It can be rotated in a vertical plane. The driving roller 80, the driven roller 81, the roller driving motor 82, and the like described above correspond to the rotational driving means of the present invention.

Yes. The screw shaft 83 is driven to rotate by the drive motor 84 so that the driven roller 81 can be relatively moved along the guide shaft 85 in the front-rear direction (a direction parallel to the traveling direction of the carriage 60). ing. Accordingly, when the reel 3 is exchanged, the driven roller 81 is moved from the rear position (the side opposite to the connecting portion 60b) shown by the solid line in FIG. 6 to the front position (connecting portion) shown by the two-dot chain line in FIG. 60b side), the driven roller 81 does not get in the way when the reel 3 is inserted and removed between the two side portions 60a, and the rear end side portion of the carriage 60 is between the two side portions 60a. The reel 3 can be taken in and out while rolling.

  Further, the shaft member 74 is attached to the reel 3 disposed between the two side portions 60a, and the driven roller 81 is moved in the front-rear direction in a state where the reel 3 is pivotally supported via the shaft member 74. Thus, the reel 3 can be driven up and down. That is, in the state where the driven roller 81 is at the front position indicated by the two-dot chain line in FIG. 6 and the reel 3 is in contact with the running surface 100 between the two side portions 60a, the driven roller 81 is moved backward. When moved, the arm 75 connected to the shaft member 74 rotates counterclockwise in FIG. 6, while the reel 3 is pushed upward by the driven roller 81, and the reel 3 is rotationally driven by the drive roller 80. Will be possible. Conversely, when the driven roller 81 is in the rear position (the position indicated by the solid line in FIG. 6) and the reel 3 is rotatable, and the driven roller 81 is moved from the rear to the front, the weight of the reel 3 is driven. The reel 3 can be lowered and come into contact with the running surface 100 while the arm 75 rotates in the clockwise direction of FIG. It becomes a state. According to this configuration, the driven roller 81 that is movable in the front-rear direction also serves as means for driving the reel 3 disposed between the two side portions 60a up and down, so that the hydraulic pressure according to the first embodiment is used. There is no need to separately provide vertical drive means such as the cylinder 29 (see FIG. 1), which is advantageous in terms of manufacturing cost.
