Description

  The present invention relates to an apparatus for preventing a wire coil from overturning when a wire coil coiling work is performed at a distribution center that collects and distributes wire coils.

  For example, various wire coils (hereinafter also simply referred to as “coils”) manufactured and shipped at steelworks are unloaded by cranes at distribution centers and once stored in warehouses by forklifts. Shipped according to orders from.

  By the way, the surface of the wire coil, particularly the end face, may be wrinkled during conveyance or handling. Such a coil with a hook does not look good and its quality value is lowered. Therefore, the coil is usually shipped after it is scraped in a warehouse.

  When coil scraping work is performed in the warehouse, a large number of coils to be shipped are moved from the storage place to the scraping work place with a forklift, and then an operator visually observes both end faces of each coil. The presence or absence of wrinkles is observed, and if wrinkles are found, they are manually removed using a hand grinder or the like.

  As described above, since the scraping work requires visual observation of both end surfaces of a large number of coils and the removal work when there are wrinkles, a plurality of coils are attached to improve the efficiency of the work. In the state where it is stood in the scooping work place, it is temporarily placed at an appropriate interval to carry out the scooping work. Moreover, in the warehouse, the fork of the forklift is pierced through the hollow part of the coil, and handling work such as transfer, storage and unloading is performed, and it is most convenient to handle the coil in an upright state. . For this reason, it is customary to perform the scraping operation while the coil is in an upright state.

  In order to temporarily place the coil while standing on the floor surface, for example, as shown in FIG. 5, a scraping work place 102 is provided at one corner in the warehouse 101 so as to be parallel to each other on the floor surface 103. A plurality of coil temporary placement rows 105 made of a pair of square bars 104 laid on the substrate are provided. Then, the coil 106 is placed between the pair of parallel square members 104 in a standing state and placed.

  However, the wire coil 106 placed on the floor surface 103 (coil temporary placement row 105) in an upright state differs from the case where a large number of coils are placed almost without any gap as in the storage place. In the case where the coil is placed alone with a gap between them, especially in the case of a coil having a small coil width with respect to the coil diameter, the coil easily falls down in the axial direction during the scraping operation, and there is a risk. Even when the coil width is not so small, even when the hoop pressure (clamping force) of the coil binding belt is small and loosely bound, the load collapses easily in the direction of the coil axis, and there is a risk of coil falling. Although it is desirable to increase the coil hoop pressure to some extent from the viewpoint of preventing collapse of the load, the hoop pressure is intentionally reduced according to the demand of a customer who does not want to bend the coil by tightly binding. May tie loosely. As described above, since the scraping work is performed while being aware of the danger of the coil falling over, there is a problem in that it is impossible to concentrate on the work with peace of mind and the burden on the worker is large and the work efficiency is low.

  In order to avoid the danger due to the falling of the coil, it is conceivable to carry out the scraping work with the coil lying on its side, but this is not realistic because the working efficiency is significantly reduced. That is, if the coil is laid down, only one end face can be scraped off at a time, so that it is necessary to perform the scraping operation again with the coil turned over. Moreover, as described above, the handling work by the forklift is suitable for performing with the coil standing upright, so that the coil with the forklift has been turned upside down, turned over, turned over, or overlaid To return to the standing state, skilled operation is required, and the work load is greatly increased. In addition, there is a high possibility that a new wrinkle will be attached to the coil during these extra handling operations. In addition, it is not practical to introduce a dedicated coil overturning device in place of handling by these forklifts because the equipment cost is too high in a distribution center that handles relatively inexpensive wire coils.

  It is also possible to assemble a wooden frame called “mote” at the rigging place and hold the coil in a standing state to carry out the culling work, but the wooden frame is in the way, making it difficult to remove the cocoon. Therefore, this method is also not realistic.

Various proposals have been made as devices for preventing a wire coil from overturning (see, for example, Patent Documents 1 to 4), and all of them are intended to prevent the coil from overturning when the coil is conveyed by a coil carriage or a stacker crane. As described above, a movable arm or the like is attached to a cart or the like, and the configuration is completely different from the present invention.

As a result, the coil can be reliably prevented from falling during the end work of the end face of the wire coil, so that the end work can be efficiently and safely performed at low cost.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Embodiment 1
(Device configuration)
An example of the wire coil overturn prevention device according to the embodiment of the present invention is shown in FIGS. In addition, this wire coil fall prevention device shall be installed in the conventionally used scraping work place demonstrated in FIG. 5 in the said background art, and hereafter, the same code | symbol is attached to the same place, the same member, etc. A description will be given.

  As shown in the plan view of FIG. 1, rails 2 and 2 are laid on both side floor surfaces 103 of the scraping work place 102 so as to be orthogonal to the temporary coil placement row 105. Then, the wire coil overturn prevention device 1 is erected on the rails 2 and 2 so as to straddle the scraping work place 102.

  As shown in FIG. 2, the wire coil toppling prevention device 1 includes a portal frame 3 erected on rails 2, 2 laid on a floor surface 103 so as to be able to move forward and backward, and both the portal frame 3. A horizontal bar 4 that is horizontally passed between the pillars 3a and 3a and is suspended from the beam 3b of the portal frame 3 so as to be freely raised and lowered, and is suspended from the horizontal bar 4 and upper end surfaces 105a and 105a of the wire coil 106. It consists of two pairs of coil support claws 5 and 5 sandwiching.

  For example, the gate-shaped frame 3 may be configured such that wheels 3c are attached to the lower ends of both supports 3a, 3a and can be moved forward and backward on the rail 2 with an electric motor or the like. In addition, as shown in FIG. 2, the rails 2 and 2 are good to make it the groove shape dug down from the floor surface 103. As shown in FIG.

  Further, the horizontal bar 4 is suspended by, for example, a wire rope 8 via a beam 3b of the portal frame 3, and rollers 4a and 4a are attached to both left and right ends of the horizontal bar 4, and these rollers 4a and 4a are connected to the gate. What is necessary is just to comprise so that it may slide on both the support | pillars 3a and 3a of the shape frame 3, and to wind up and unwind the wire rope 8 manually or with an electric motor etc., and to adjust height.

  Here, since the coil diameter D is in the range of about 1100 to 1300 mm, the height of the gate-shaped frame 3 and the range in which the horizontal bar 4 can be raised and lowered are adjusted so that the height of the coil support claw 5 can be adjusted in this range. What is necessary is just to set suitably.

Further, for example, as shown in FIG. 3, the horizontal bar 4 has a large number of pin holes 6 in the lateral direction, and each coil support claw 5 has two laterally attached portions 5 a to the horizontal bar 4. The pin hole 7 is assumed to be provided. The distance between the pair of coil support claws 5 and 5 can be changed by fixing the two pin holes 7 of each coil support claw 5 and any one of the many pin holes 6 of the horizontal bar 4 with pins. What is necessary is just to comprise.

  Since the coil width W is about 500 mm at the minimum and about 1300 mm at the maximum, the plurality of pin holes 6 are arranged so that the distance between the pair of coil support claws 5 and 5 can also be changed at least within this range. The pitch and the number of holes may be set as appropriate.

  If the pitch of the large number of pin holes 6 is too small, the number of holes becomes too large and the strength of the horizontal bar 4 decreases. On the other hand, if the pitch is too large, both ends of the coil 106 are covered by a pair of coil support claws 5 and 5. When the surface 106a is sandwiched, the gap may become large, and the coil 106 may slip through the pair of coil support claws 5 and 5 and fall down, so that it is 20 to 100 mm, more preferably 30 to 70 mm. What is necessary is just to adjust suitably in the range. Further, the interval between the two pin holes 7 of the coil support claw 5 is an integral multiple of the pitch of the pin holes 6 so that each pin hole 7 and any one of the many pin holes 6 of the horizontal bar 4 always match. However, in order to suppress the rattling of the coil support claw 5 as much as possible within a range in which the mounting portion 5a to the horizontal bar 4 is not excessively large, it is 1 to 5 times the pitch of the pin holes 6, more preferably 2 What is necessary is just to adjust suitably in the range of -4 times.

  Further, if the length of the coil support claw 5 hanging from the horizontal bar 4 is too short, there is an increased risk that the coil 106 slips between the pair of coil support claws 5 and 5 and falls. In addition, there is an increased risk that the coil support claw 5 will be deformed due to excessive torque when the weight of the coil 106 is supported at the tip of the coil support claw 5, so that it is 200 to 600 mm, more preferably 300 to 500 mm. It may be adjusted as appropriate within the range.

(How to use the device)
Next, a method for supporting the coil 106 using the wire coil toppling prevention device 1 will be described (see FIGS. 1 to 3).

  First, the wire coil fall prevention device 1 is kept waiting at the end of the scraping work place 102, and the horizontal bar 4 winds the wire rope 9 so that the coil support claw 5 moves to the coil 106 when the wire coil fall prevention device 1 moves. Raise it to a height where it will not touch. Then, by adjusting the pinning position of the pin hole 7 of each coil support claw 5 to the pin hole 6 of the horizontal bar 4, the distance between the pair of coil support claws 5 and 5 is slightly wider than the coil width to be shipped. Keep in line with.

  Next, the coil 106 to be shipped is picked from the storage location in the warehouse 101 by a forklift, and placed at a predetermined interval on the coil temporary placement row 105 in the scraping work location 102.

  Next, the portal frame 3 of the wire coil toppling prevention device 1 is moved immediately above the temporary coil placement row 105 that performs the scraping operation. Then, the wire rope 9 is rewound and the horizontal bar 4 is lowered, and the pair of coil support claws 5 and 5 are lowered to a position where the upper end faces 106a and 106a of the coil 106 are sufficiently sandwiched. At this time, since the distance between the pair of coil support claws 5 and 5 is slightly wider than the coil width, the coil 106 does not wrinkle even if the coil support claws 5 come into contact with the coil 106.

  Thus, even if the coil 106 tries to fall in the axial direction during the scraping operation, any one of the pair of coil support claws 5 and 5 always supports the upper end surface 106a of the coil 106, so that the coil 106 is surely turned over. Can be prevented.

  Then, after the scraping work for all the coils 106 placed on the coil temporary placement row 105 is completed, the wire coil overturn prevention device 1 is moved onto the next coil temporary placement row 105 by the same operation as described above. By doing so, it is possible to perform the scraping work sequentially.

  In addition, the applicant of the present invention is that the pitch of the pin holes 6 of the horizontal bar 4 is 50 mm, and the interval between the two pin holes 7 of the coil support claw 5 is 150 mm, which is three times the pitch of the pin holes 6 of the horizontal bar 4 Although the length of the support claw 5 hanging from the horizontal bar 4 is about 400 mm and has been put into practical use for more than 6 months, neither the coil 106 falls nor the coil support claw 5 is deformed at all.

[Embodiment 2]
(Device configuration)
In the first embodiment, an example in which one horizontal bar 4 is provided between both the pillars 3a and 3a of the portal frame 3 is shown. However, in this embodiment, as shown in FIG. One column 9 is suspended from the middle of 3b, and the horizontal bar 4 and at least one pair of coil support claws 5, 5 are provided between the columns 3a, 3a of the portal frame 3 and the columns 9 described above. The example which each provided is shown. In the figure, a pair of coil support claws 5 is provided between the support post 3a on the left side of the portal frame 3 and the other support column 9, and the support post 3a on the right side of the portal frame 3 and the above support column 9 are provided. An example is shown in which two pairs of coil support claws 5 are provided between another support column 9.

  Accordingly, the coil 106 having a relatively wide coil width can be supported on the left side of the drawing, and two coils 106 having a narrow coil width can be simultaneously supported on the right side of the drawing. As a result, even when coiling coils having different coil diameters and coil widths, a plurality of coils 106 can be supported simultaneously without raising and lowering the horizontal bar 4 and changing the distance between the pair of coil support claws 5 and 5 one by one. As a result, the work efficiency can be greatly improved.

[Modification]
In the first embodiment, an example in which two pairs of coil support claws 5 and 5 are provided on the horizontal bar 4 is shown, but one pair or three or more pairs may be provided. In the second embodiment, an example is shown in which a pair of coil support claws 5 and 5 are provided on the horizontal bar 4 on the left side of the drawing, and two pairs of coil support claws 5 and 5 are provided on the horizontal bar 4 on the right side of the drawing. Two or more pairs may be provided on the left side of the drawing, or one or three or more pairs may be provided on the right side of the drawing.

  In the second embodiment, an example in which only one support column 9 is provided in the middle of the beam 3b of the portal frame 3 is shown, but two or more columns may be provided.

  Moreover, in the said Embodiment 1, although the example which provided the pin hole 7 of the coil support nail | claw 5 in the horizontal direction in the attaching part 5a was shown, you may provide only one. However, it is preferable to provide two because the rattling of the coil support claws 5 can be more reliably prevented.

  In the first and second embodiments, as a means for adjusting the distance between the pair of coil support claws 5, 5, the pin hole 7 of the coil support claw 5 is pinned to any of the many pin holes 6 of the horizontal bar 4. Although an example of performing by fixing is shown, instead of providing a pin hole, for example, the structure for attaching each coil support claw 5 to the horizontal bar 7 is a gear structure so that each coil support claw 5 is moved by an electric motor or the like. Also good.

  The present applicant has introduced the wire coil toppling prevention device 1 having the device configuration described in the second embodiment (see FIG. 4) at the scraping work place in the warehouse of the distribution center. As described above in the first embodiment, the pitch of the coil support claw fixing holes 6 is 50 mm, and the interval between the two horizontal bar fixing holes 7 is 150 mm, which is three times the pitch of the coil support claw fixing holes 6. The length of the coil support claw 5 hanging from the horizontal bar 4 was about 400 mm. As a result of the introduction of this device, there were about 1 to 2 near-miss accidents per month before the introduction of this device, but after the introduction of this device, more than 6 months have passed since the introduction. No accidents related to coil fall have occurred. In addition, workers can now concentrate safely and securely on the scraping work, improving work efficiency and greatly reducing the burden on the workers.
