Description

  The present invention relates to an apparatus for feeding a wire wound around a wire drum in a predetermined direction while rotating the wire drum around an axis.

  When replacing a wire used in a crane or the like with a new wire, if the wire delivered in a state wound on a wire drum is unwound from the wire drum and mounted on the crane or the like, The following measures have been taken in the past because of the occurrence of resentment and various harmful effects.

  That is, after unwinding all the wires from the wire drum at the time of delivery, rewinding them into a figure 8 and removing the twist, after replacing the crane wires, remove the wires from the cotter of the winding drum at the top of the crane and remove the wires. A method of removing the twist of the wire, or a method of removing the wire from the wire drum by unwinding all the wires from the wire drum at the time of delivery has been implemented.

  However, the above-described method requires a great deal of labor and time for unwinding all the wires from the wire drum, which not only increases the physical burden on the operator, but also rewinds the wire unwound from the wire drum. There are problems such as requiring a vast space to stretch out.

  On the other hand, as a prior art related to the present invention, for example, there is a “cable sending device” described in Patent Document 1. This "cable delivery device" is a device that can send out the cable wound around the bobbin while rotating the bobbin around the axis, and when the cable is twisted (turned) during the delivery operation, It also has a function to remove it.

Japanese Utility Model Publication No. 63-113415

  The “cable delivery device” described in Patent Document 1 is excellent in that it has a function of removing twisting (twisting) of the cable generated during delivery, but the bobbin around which the cable is wound is connected to the horizontal rotation shaft. The bobbin is in a cantilever state because it is supported by the torsion release supporting mechanism. For this reason, the torsion release support mechanism that supports the entire weight of the bobbin around which the cable is wound and the mounting portion that supports these must be constructed to be robust. Therefore, it is easy to increase the size and weight of the device.

  In the case of the “cable delivery device”, when the bobbin is attached to or detached from the bobbin holding member, the bobbin must be moved up and down by placing the bobbin on the mounting table of the bobbin attachment holding mechanism. As the weight of the bobbin increases, workability deteriorates.

  As described above, the “cable delivery device” can be suitably used when the bobbin around which the cable is wound is relatively light, but a heavy wire such as a crane wire is wound around the bobbin. Since it is not suitable for wire delivery work from a wire drum, it lacks versatility.

  Furthermore, in the case of the “cable delivery device”, the position (height) of the cable delivered from the bobbin changes as the remaining amount of the cable wound around the bobbin decreases as the delivery work progresses. As a result, the sending operation may become unstable.

  The problem to be solved by the present invention is to provide a wire delivery device that is excellent in versatility, can perform stable wire delivery work, and can easily and safely perform wire scraping work.

The wire feeding device of the present invention includes a drum holding means for holding a wire drum having an axial center arranged in a substantially horizontal state so as to be rotatable about the axis at both side portions of the axial center, and the drum holding means in a virtual vertical direction. A turntable that can be pivoted around the line ,
In order to hold the wire fed from the wire drum movably in the feeding direction at a position above the wire drum during wire feeding work, the wire is placed at a position higher than the uppermost portion of the outer peripheral edge of the flange member of the wire drum. A guide member arranged in a state where the relative positional relationship with the drum is constant ;
During the wire scraping operation, the wire drum held between the wire drum and the guide member is erected more than during the delivery operation by changing the relative positional relationship between the wire drum that has stopped rotating and the guide member. state and a moving means capable of changing the,
As the advance / retreat means, a moving mechanism capable of changing a distance between the turntable and the guide member in a direction including the wire feeding direction is provided on at least one of the turntable or the guide member . Here, the above-mentioned “state standing more than during the delivery operation” means a state in which the inclination angle is closer to the vertical direction than the inclination angle of the wire when being delivered from the wire drum (hereinafter the same). .)

  With such a configuration, the wire drum in which the shaft center is arranged in a substantially horizontal state is held by the drum holding means so as to be rotatable around the drum shaft center at both side portions of the shaft center. It can be held stably without being affected by the weight or size of the drum. Moreover, since the wire sent out from the wire drum is held at a predetermined position by the guide member without being affected by the remaining amount of wire in the wire drum, a stable wire sending operation can be performed. Since such an effect can be obtained without being influenced by the size of the wire drum, it is excellent in versatility.

  Further, when it is necessary to scrape the wire during the wire feeding work, the feeding work is interrupted, and the relative positional relationship between the wire drum and the guide member is changed by the advance / retreat means, and the wire drum, the guide member, After the wire held between the two is changed to a more upright state than during the feeding operation, the turn can be removed by simply turning the wire drum around the virtual vertical line together with the turntable. In this case, since the wire is held in an upright state by the guide member as compared with the feeding operation, the wire drum can be easily turned and the scraping operation is easy. Further, since it is not necessary for the operator to touch the wire during the scraping operation, the safety is also good. After the turning-off operation is completed, if the relative positional relationship between the wire drum and the guide member is returned to the original state by the advance / retreat means, the wire also returns to the original inclination angle, so the wire feeding operation can be easily resumed. can do.

Here, in the wire delivery device, as the advance / retreat means, a moving mechanism capable of changing a distance between the turntable and the guide member in a direction including the wire delivery direction in at least one of the turntable or the guide member. Ru the provided Tei.

  With such a configuration, by moving the turntable or the guide member, the distance between the wire drum and the guide member is changed to change the relative positional relationship between them, and the two are held between the two. It is possible to erect the wire being put up or return it to its original state more than during the delivery work, which is effective in facilitating the scraping work.

  Further, a pedestal for holding the guide member at a predetermined position, and a carriage mounted on the pedestal in a state of being movable in a direction approaching and separating from the guide member, the drum holding means and the turntable are provided. The drum holding unit provided may be configured to be attached to the carriage.

  With such a configuration, an integrated wire delivery device composed of a gantry, a carriage, and a drum holding unit can be formed. Therefore, workability when carrying in, installing, removing, etc. of the wire delivery device is improved. improves.

  In this case, the drum holding unit can be detachable from the carriage.

  With such a configuration, it is possible to remove the drum holding unit from the carriage as necessary, so that convenience in transportation and storage is improved. Further, if a plurality of types of drum holding units are prepared according to the size of the wire drum, etc., it is possible to easily cope with a change in the wire type.

  On the other hand, a lock mechanism that prevents movement of the carriage and turning of the turntable can also be provided.

  With such a configuration, it is possible to hold the carriage and the turntable in a predetermined state by causing the lock mechanism to function when performing a wire feeding operation or a wire scraping operation, Safety can be improved.

  Furthermore, the drum holding means and the turntable can be arranged so that the drum axis and the virtual vertical line are orthogonal to each other.

  With such a configuration, when the wire scraping work is performed, the horizontal turning work of the wire drum by turning the turntable can be smoothed, which is effective in improving workability.

  According to the present invention, it is possible to provide a wire delivery apparatus that is excellent in versatility, can perform stable wire delivery work, and can easily and safely perform wire scraping work.

Of a pair of support pillars 11a and 11b erected on the one short side member 10a side, and beam members 12a and 12b extending horizontally from the support pillars 11a and 11b toward the other short side member 10b side, respectively. A guide member 13 that is pivotally supported near the tip, a cart 30 that is movable along the longitudinal direction of the long sides 10b and 10c of the gantry 10, and a drum holding unit 50 that is detachably mounted on the cart 30 And. The drum holding unit 50 includes a drum holding means 60 that holds the wire drum 90 rotatably around an axis 90c, and a turntable 80 that holds the drum holding means 60 so as to be rotatable around a virtual vertical line L.

  As will be described later, when the relative positional relationship between the wire drum 90 and the guide member 13 is changed by moving the carriage 30 along the longitudinal direction of the long sides 10b and 10c of the gantry 10, the wire drum 90 and the guide member 13 are changed. The wire W held between the two can be changed to a more upright state than during the delivery operation. In other words, the carriage 30 is changed to a state where the wire W held between the wire drum 90 and the guide member 13 is more upright than during the delivery work by changing the relative positional relationship between the wire drum 90 and the guide member 13. It constitutes a moving mechanism that is one of the possible advancing and retracting means.

  The guide member 13 is a cylindrical roller whose both ends are rotatably supported in a substantially horizontal posture on bearings 14a and 14b attached to the lower surfaces of the beam members 12a and 12b, respectively. Above the guide member 13, a horizontal bar member 15 is disposed with a gap through which the wire W can be inserted. Moreover, the horizontal bar material 16 is arrange | positioned in the position lower than the guide member 13 between support | pillar 11a, 11b. In addition, a pair of left and right side guide members 18 a and 18 b are arranged in the vertical direction near the both ends of the guide member 13 in a state of three-dimensionally intersecting the guide member 13 and the horizontal bar member 15.

  A carriage 30 that is a moving mechanism in the wire delivery device 100 is disposed on the inner peripheral side of the gantry 10, and includes a main body 31 that detachably mounts the drum holding unit 50, and a plurality of shafts that are pivotally supported on the periphery of the main body 31. The main body 31 is provided with a fitting tube 33 that includes a wheel 32 and that fits and locks a plurality of protrusions 81 formed on the lower surface of the turntable 80. The plurality of wheels 32 can travel inside the long side members 10c, 10d along their respective longitudinal directions. Stoppers 34a, 34b for stopping the movement of the carriage 30 at predetermined positions (wire delivery work position, wire scraping work position) are provided at both ends of the traveling region of the wheels 32 of the long side members 10c, 10d. . Further, a lock plate 17 having a vertical through hole is provided in the horizontal direction at a portion of the long side member 10c near the support 11a.

  As shown in FIGS. 5 and 6, the drum holding unit 50 includes a turntable 80 that is detachably mounted on the main body 31 of the carriage 30, and a drum holding means 60 that is integrally formed on the turntable 80. And. The turntable 80 includes a support plate 82 that is placed immediately above the main body 31 of the carriage 30, and a rotating plate 84 that is attached to the support plate 82 via a support shaft 83. The rotating plate 84 can turn around a virtual vertical line L that is the axis of the support shaft 83 with respect to the support plate 82.

  On the lower surface of the support plate 82, a plurality of protrusions 81 having an inverted truncated cone shape project downward. A lock plate 85 having a through hole for fixing the carriage 30 at a predetermined position (wire scraping work position) is provided at the corner edge of the support plate 82 in the horizontal direction. Further, in order to prevent the rotating plate 84 from rotating and the carriage 30 from moving during the wire feeding operation, a lock plate 86 having a through hole is provided in the horizontal direction at the rear edge of the rotating plate 84. Has been.

  The drum holding means 60 includes a pair of support walls 61a and 61b erected on the support plate 82 of the turntable 80, and bowl-shaped bearing portions 62a attached to the respective support walls 61a and 61b. 62b, an operation handle 63 that is gripped and used by an operator when the drum holding unit 50 is moved or turned, and a brake 64 for stopping the rotation of the wire drum 90 held by the drum holding means 60. And.

  The support walls 61a and 61b are formed of a plate material having a substantially Mt. Fuji shape when viewed from the side, and are opposed to each other with an interval wider than the width of the wire drum 90 (the interval between the outer surfaces of the pair of flange members 90a and 90b shown in FIG. 4). Has been placed. Both ends of the shaft body 91 that is rotatably inserted in the core hole of the wire drum 90 are placed on the bearing portions 62a and 62b positioned at the top portions of the support walls 61a and 61b, and a disengagement preventer (not shown). The wire drum 90 is rotatably attached to the drum holding means 60.

  The brake 64 is pivotally supported by the support walls 61a and 61b via a support shaft 64a. If necessary, a brake shoe 64c provided on the opposite side when the operator steps on the stepping portion 64b is pressed against the periphery of the wire drum 90. The rotation can be stopped. If the rotating wire drum 90 immediately after the wire W delivery operation is interrupted is suddenly stopped by the brake 64, the wire drum 90 and the wire delivery device 100 as a whole are dragged in the direction in which the wire W is delivered. Since this may occur, the braking force of the brake 64 is set to be suppressed to such an extent that the wire drum 90 does not stop suddenly.

  Next, how to use the wire delivery device 100 will be described with reference to FIGS. As shown in FIG. 7A, a drum holding unit 50 in which a wire drum 90 is rotatably held via a shaft body 91 is placed on a carriage 30, and a lock pin P1 is attached as shown in FIG. The lock plate 86 is inserted from a through hole (not shown) toward the lock hole 10 e of the short side member 10 b of the gantry 10. Accordingly, the drum holding unit 50 is locked so as not to move with the carriage 30 and the wire drum 90 does not rotate around the virtual vertical line L.

  Thereafter, the wire W wound around the wire drum 90 is pulled out, and between the side guide members 18a and 18b, between the guide member 13 and the horizontal bar member 15, and above the horizontal bar member 16, the object. When it is extended to the place, as shown in FIG. 1, the wire W can be sent out in the direction of the arrow X, and the wire sending work can be started.

  As shown in FIG. 1, during the wire feeding operation, the wire drum 90 in which the shaft center 90 c of the wire drum 90 is arranged in a substantially horizontal state is rotated around the shaft center 90 c at both side portions of the wire drum 90 by the drum holding means 60. Therefore, the wire drum 90 can be stably held regardless of the weight and size of the wire drum 90. Further, since the wire W fed out from the wire drum 90 is held at a predetermined position by the guide member 13 without being affected by the remaining amount of wire in the wire drum 90, a stable wire feeding operation can be performed.

  When it is necessary to scrape the wire during the wire feeding operation, the feeding operation is interrupted to stop the rotation of the wire drum 90, and the lock pin P1 is removed. Then, as shown in FIG. By moving in the direction (direction approaching the support columns 11a and 11b), the wire drum 90 is caused to enter the lower region of the guide member 13 together with the drum drum holding unit 50. Since the carriage 30 stops when the wheel 32 on the front side of the carriage 30 comes into contact with the stopper 34b, the lock pin P2 is locked from a through hole (not shown) of the lock plate 85 in this state as shown in FIG. If it inserts toward the through-hole of the board 17, it will be latched so that the trolley | bogie 30 may not move, and it will be in the state shown in FIG.

  That is, when the carriage 30 is moved as described above, the relative positional relationship between the wire drum 90 and the guide member 13 changes, and the inclination angle of the wire W held between the wire drum 90 and the guide member 13 is sent out. It becomes a standing state (state shown in FIG. 2) rather than a working state (state shown in FIG. 1).

  Thereafter, when the wire drum 90 held by the drum holding means 60 together with the rotating plate 84 of the turntable 80 is turned 360 degrees around the support shaft 83 (virtual vertical line L), the wire W can be removed. In this case, since the wire W is held in an upright state by the guide member 13 positioned above the wire drum 90, the wire drum 90 can be easily swung and the scraping operation is easy. is there. Moreover, since it is not necessary for an operator to touch the wire W during the scraping operation, safety is also good.

  In order to smoothly perform the wire W winding operation, the position of the guide member 13 is set between the inner side surfaces of the pair of flange members 90a and 90b forming the wire drum 90, as shown in FIG. It is desirable to arrange in the region R at a position higher than the uppermost part of the outer peripheral edges of the flange members 90a and 90b.

  When the scraping operation is finished, the lock pin P2 (see FIG. 2) is extracted, and as shown in FIG. 7D, the drum holding unit 50 and the wire drum 90 together with the carriage 30 are retracted from the lower region of the guide member 13, When the lock pin P1 is moved from the through hole (not shown) of the lock plate 86 toward the lock hole 10e of the short side member 10b of the gantry 10 after being moved to the original position on the back side of the gantry 10, FIG. The wire sending operation can be resumed.

  In the wire W feeding operation shown in FIG. 1 and the scraping operation shown in FIG. 7, it is not necessary for an operator to enter the area between the wire drum 90 and the columns 11a and 11b. It is also excellent in terms. Also, the virtual circle C shown in FIG. 3 shows the outermost locus when the rotating plate 84 and the wire drum 90 of the turntable 80 turn around the support shaft 83, but within the range of the virtual circle C. As long as there are no obstacles, the scraping operation can be performed smoothly and safely.

  Next, based on FIG. 8, FIG. 9, the wire delivery apparatus 200,300 which is the 2nd, 3rd embodiment of this invention is demonstrated. In FIGS. 8 and 9, the parts denoted by the same reference numerals as those in FIGS. 1 to 7 are parts having the same structure and function as the constituent parts of the wire sending device 100 described above, Description is omitted.

  In the wire delivery device 200 shown in FIG. 8, the lower end portion of the support 11a (11b) is attached to the gantry 10 via a carriage 201 that can travel along the longitudinal direction of the long side member 10d (10c) of the gantry 10. ing. The wire delivery operation by the wire delivery device 200 can be performed in the state shown in FIG. 8. When the wire W needs to be scraped off during the wire delivery operation, the carriage 201 is moved to move the wire drum 90. If the relative positional relationship with the guide member 13 is changed and the guide member 13 is made to enter the upper region of the wire drum 90, the wire W stands up more than during the delivery operation, as in the case shown in FIG. The wire W can be scraped off according to the procedure shown in FIGS. 7B and 7C.

  In other words, the carriage 201 is changed to a state where the wire W held between the wire drum 90 and the guide member 13 is more upright than during the delivery work by changing the relative positional relationship between the wire drum 90 and the guide member 13. It constitutes a moving mechanism that is one of the possible advancing and retracting means.

  When the scraping work is finished, if the pillar 11a (11b) is returned to the original position together with the carriage 201, the wire W returns to the original state (the same inclination angle as that during the sending work), so that the wire sending work can be resumed. it can. Since a locking mechanism (not shown) is provided to lock the carriage 30 so that the carriage 30 does not move during the wire feeding operation and the wire scraping operation, workability and safety during the operation are provided. Can be secured sufficiently.

  In the wire delivery device 200, the carriage 201 functions as a moving mechanism. However, the invention is not limited to this, and the lower end of the support 11a (11b) is fixed to the gantry 10 as in the wire delivery device 100 shown in FIG. If a mechanism for moving the guide member 13 by extending and contracting the beam members 12a (12b) in the longitudinal direction is provided, the relative positional relationship between the wire drum 90 and the guide member 13 is changed and the wire drum 90 is provided. The wire W held between the guide member 13 and the guide member 13 can be changed to a more upright state than during the sending operation, or returned to the state during the sending operation.

  In the wire delivery device 300 shown in FIG. 9, the lower end portion of the column 11 a (11 b) can be rotated near the short side member 10 a of the gantry 10 via a support shaft 301 parallel to the short side member 10 a of the gantry 10. Is attached. The wire delivery operation by the wire delivery device 300 can be performed in the state indicated by the solid line in FIG. 9. When the wire W needs to be scraped off during the wire delivery operation, the support 11a (11b) is supported on the support shaft. When the guide member 13 is tilted to the center of 301 and the guide member 13 enters the upper region of the wire drum 90, the relative positional relationship between the wire drum 90 and the guide member 13 changes, and the state is similar to the state shown in FIG. Since the wire W held between the members 13 is in a standing state more than during the delivery operation), the wire W can be scraped off by the procedure shown in FIGS. 7B and 7C. .

  That is, the column 11 a (11 b) rotatably attached to the vicinity of the short side member 10 a of the gantry 10 via the support shaft 301 parallel to the short side member 10 a of the gantry 10 is formed between the wire drum 90 and the guide member 13. By changing the relative positional relationship, a moving mechanism, which is one of the advancing / retreating means that can change the wire W held between the wire drum 90 and the guide member 13 to a standing state rather than during the feeding operation, is configured. Yes.

  When the scraping operation is finished, the wire W returns to the original state (the same inclination angle as that during the feeding operation) by rotating the support column 11a (11b) about the support shaft 301 to return to the original upright state. The sending operation can be resumed. In addition, since a locking mechanism (not shown) is provided to prevent the support column 11a (11b) from rotating about the support shaft 301 during the wire feeding operation and the wire scraping operation, the workability and the operation are improved. It is possible to ensure sufficient safety.

  The wire delivery devices 100, 200, 300 and the like described with reference to FIGS. 1 to 9 exemplify the present invention, and the wire delivery device of the present invention includes the wire delivery devices 100, 200, 300 and the like described above. It is not limited to. In addition, the wire delivery device of the present invention can be suitably used in delivery work from a drum around which a member other than a wire such as a cable, an electric wire, or a string-like body is wound.

  The wire delivery device of the present invention can be widely used in fields such as the manufacturing industry and the processing industry where various types of transport machines incorporating wires are used.
