Description

Technical Field

[0001] This invention relates to a strapping supply device for steel product packaging, and more specifically to a strapping supply device for steel product packaging that enables the smooth supply of straps of various specifications to a strapping device. Background Technology

[0002] Steel products such as coils and plates produced in steel mills are typically bundled along their outer circumference using strapping devices to transfer them to subsequent processes and to customers.

[0003] However, in the prior art, there is an inconvenience in the process of installing the belt in the belt supply device, which requires different loading positions depending on the specifications of the belt wound in the form of coils.

[0004] At this point, the operator needs to manually adjust the installation position of the belt, which serves as a weight, according to the inner diameter of the belt, which reduces the efficiency of the operation.

[0005] In addition, when supplying or replacing the belt to the strapping device, the operator needs to guide multiple guide rollers that are located in the direction of belt movement, which makes the installation work inconvenient and complicated, and requires multiple operators, resulting in inefficiency.

[0006] In particular, there is a problem of work interruption caused by belt detachment and kinking during the process of replacing the belt when the supply is exhausted and connecting it to a new belt.

[0007] At the same time, there is a problem that during the replacement of the straps, the straps can easily become tangled or untied, which can lead to defects in the binding of steel products and cause safety accidents.

[0084] The structure of the present invention as described above will be explained in detail below with reference to the accompanying drawings.

[0085] Figure 1 This is a front view illustrating an embodiment of the steel product packaging with a supply device according to the present invention. Figure 2 This is a side view illustrating an embodiment of the steel product packaging with a supply device according to the present invention. Figure 3 yes Figure 1 AA-line cross-section diagram, Figures 4 to 7 This is a side view illustrating another embodiment of the loading unit and the supply unit in this invention. Figure 8 This is a front view illustrating yet another embodiment of the steel product packaging with a supply device of the present invention. Figures 9 to 14 This is a reference diagram illustrating the operating state of the supply device for steel product packaging according to the present invention.

[0086] The present invention includes: a loading unit 110 configured to load a coil-wound tape A and move toward a supply unit 120, and to adjust its height according to the specifications (inner diameter or weight) of tape A; a supply unit 120 configured to supply tape A by fixing and rotating the inner diameter B of tape A received by the loading unit 110; a tension holding unit 130 configured to allow tape A received by the supply unit 120 to circulate through a front guide roller 132, an intermediate guide roller 133, a rear guide roller 134, and a moving roller 135, thereby maintaining tension on tape A by the weight of the moving roller 135 moving vertically, while moving toward a strapping device; and a tape guiding unit 140, which, when supplying or replacing tape A, moves the moving roller 135 upward to create a passage so that tape A can circulate through the front guide roller 132, the intermediate guide roller 133, the rear guide roller 134, and the moving roller 135.

[0087] In particular, the loading unit 110 loads the coiled strip A vertically in the vertical direction, adjusting the height so that the mounting part 126 of the supply unit 120 can be inserted and fixed at the inner diameter B of the strip A.

[0088] Such an implementation of the loading unit 110 is, for example... Figure 2 The device includes: a main body 111, configured to move toward the supply unit 120; a lifting body 112, configured to move vertically above the main body 111; a support body 113, vertically positioned on one side of the lifting body 112 to support the side of the belt A; a loading section 114, configured to load the belt A onto the other side of the lifting body 112; and an adjusting member 115, configured to allow the lifting body 112 to move vertically according to the specifications of the belt A, with the mounting section 126 of the supply unit 120 inserted into the inner diameter B of the belt A.

[0089] Another embodiment of the loading unit 110 is, for example... Figure 4 The device includes: a main body 111, configured to move toward the supply unit 120; a lifting body 112, configured to move vertically above the main body 111; a support body 113, formed on one side of the lifting body 112; a rotating shaft 113a, configured to face the supply unit 120 from the side above the support body 113; a reinforcing body 113b, rotating in front of the rotating shaft 113a; an elastic body 113c, radially shaped in front of the reinforcing body 113b; a cover 113d, supporting the side of the belt A in front of the elastic body 113c; and an adjusting member 115, configured to allow the lifting body 112 to move vertically according to the specifications of the belt A, with the mounting portion 126 of the supply unit 120 inserted into the inner diameter B of the belt A.

[0090] Meanwhile, another embodiment of the loading unit 110 is, for example... Figure 5The device includes: a main body 111, configured to move toward the supply unit 120; a lifting body 112, configured to move vertically above the main body 111; a support body 113, formed on one side of the lifting body 112; a reinforcing body 113e, formed at the upper front of the support body 113; multiple rollers 113f, formed in front of the reinforcing body 113e; a rotating body 113g, which rotates by means of the multiple rollers 113f; an elastic body 113h, which is radially shaped in front of the rotating body 113g; a cover 113d, which supports the side of the belt A in front of the elastic body 113h; and an adjusting member 115, configured to allow the lifting body 112 to move vertically according to the specifications of the belt A, while the mounting portion 126 of the supply unit 120 is inserted into the inner diameter B of the belt A.

[0091] Here, when loading the strip A wound in the form of a coil, the body 111 moves in the opposite direction to the supply unit 120 to ensure loading space, and when supplying the strip A, the body 111 moves toward the supply unit 120.

[0092] At this time, a plurality of support members 111a formed below the main body 111 and a track 111b formed toward the supply unit 120 and configured to place the support members 111a on it can be used to smoothly move the loading unit 110 toward the supply unit 120 or in the opposite direction.

[0093] In particular, the support member 111a may also be formed by wheels or utilize LM blocks or the like so that it can be placed on the track 111b and moved.

[0094] On the other hand, the operator can manually push or pull the main body 111. It may also include a threaded shaft 111c formed to be threadedly connected to the lower part of the main body 111, and a drive member 111d for rotating the threaded shaft 111c. Through the operation of the drive member 111d, while the threaded shaft 111c is rotating, the main body 111 is moved toward the supply unit 120 or in the opposite direction.

[0095] Meanwhile, the lifting body 112 adjusts its height as it moves vertically through the operation of the adjusting member 115.

[0096] In addition, the support body 113 is supported on one side of the vertically erected section A.

[0097] Furthermore, when viewed from the front, the loading section 114 can be configured to load the bottom of the band A by gradually tilting downwards from the outside towards the center.

[0098] In particular, when the loading unit 110 is moved toward the supply unit 120 and the mounting part 126 is rotated while the cover 113d is in close contact with the side of the belt A, the rotating shaft 113a can rotate simultaneously, thus stably supplying the tension holding unit 130 while preventing the belt A from slipping off.

[0099] On the other hand, the elastomer 113c is located between the reinforcing body 113b and the cover 113d and performs a cushioning effect during the process of the cover 113d being in close contact with the side of the band A.

[0100] Here, the elastomer 113c uses springs of various forms and specifications.

[0101] Furthermore, the cover 113d is supported on the side of the vertically erected belt A to prevent it from detaching in the left-right direction during the supply of belt A.

[0102] Furthermore, when the mounting part 126 rotates while the cover 113d is in close contact with the side of the belt A, the rotating body 113g rotates simultaneously, and the roller 113f can stably supply tension to the tension holding unit 130 while preventing the belt A from slipping off.

[0103] At this time, when the reinforced body 113e is viewed from the side, the rollers 113f are formed in a radial pattern to assist the rotating body 113g in rotating stably.

[0104] In particular, the adjusting member 115 adjusts the height of the lifting body 112 according to the specifications of the band A, so that the mounting part 126 of the supply unit 120 can be smoothly inserted into the inner diameter B of the band A.

[0105] Such an adjusting member 115 includes: a plurality of guide shafts 115a, formed vertically on both sides above the main body 111 and configured such that the lifting body 112 can move in the vertical direction; a threaded shaft 115b, formed vertically on one side above the main body 111 and configured to be threadedly engaged with the lifting body 112; a driving member 115c for rotating the threaded shaft 115b; and a measuring sensor 115d for measuring the inner diameter B of the belt A on one or both sides of the support body 113 or measuring the weight of the belt A below the loading part 114.

[0106] At this time, the guide shaft 115a guides the lifting body 112 to move smoothly in the vertical direction.

[0107] In particular, the threaded shaft 115b can adjust the height by moving the lifting body 112 in the vertical direction along the rotation direction through the operation of the drive member 115c.

[0108] Here, the measuring sensor 115d can be used as a contact or non-contact sensor, load unit, etc. to measure the inner diameter B of belt A or the weight of belt A.

[0109] Meanwhile, the central position can be stored and set in the control unit of the cab according to the inner diameter B and weight that vary according to the specifications of the A-band. The specifications of the A-band loaded in the loading unit 110 are confirmed and compared, and the lifting body 112 is moved in the vertical direction so that the central position of the inner diameter B and the central position of the moving part 124 of the supply unit 120 are consistent with each other.

[0110] In this invention, the supply unit 120 performs the function of receiving the belt A loaded in the loading unit 110 and supplying it to the tension holding unit 130 while it is rotating.

[0111] Such an implementation of the supply unit 120 is, for example... Figure 2 The device includes: a main body 121; a rotating shaft 122 formed on the upper side of the main body 121 toward the loading unit 110; a driving member 122a for rotating the rotating shaft 122; a threaded shaft 123 formed in the length direction at the inner diameter of the rotating shaft 122; a driving member 123a for rotating the threaded shaft 123; a moving member 124 configured to be threadedly engaged with the threaded shaft 123 at the front of the rotating shaft 122 and move in the front-rear direction along the rotation direction; a support body 125 provided in the vertical direction on the middle side of the rotating shaft 122 and configured to support the side of the belt A; a plurality of mounting portions 126 formed radially on the outer side of the moving member 124 and abutting and fixed at the inner diameter B of the belt A; a joint portion 127 connecting the front of the moving member 124 and the front of the mounting portions 126; and a rotating portion 128 connecting the rear of the moving member 124 and the rear of the mounting portions 126.

[0112] Another embodiment of the supply unit 120 is, for example... Figure 6The device includes: a main body 121; a rotating shaft 122 formed on the upper side of the main body 121 toward the loading unit 110; a driving member 122a for rotating the rotating shaft 122; a moving shaft 123c formed in the length direction at the inner diameter of the rotating shaft 122; a moving member 123d for moving the moving shaft 123c in the front-rear direction; a moving member 124 attached to the front of the rotating shaft 122; a supporting body 125 provided in the vertical direction on the middle side of the rotating shaft 122 to support the side of the belt A; a plurality of mounting portions 126 formed radially on the outer side of the moving member 124 and abutting and fixed to the inner diameter B of the belt A; a joint portion 127 connecting the front of the moving member 124 and the front of the mounting portions 126; and a rotating portion 128 connecting the rear of the moving member 124 and the rear of the mounting portions 126.

[0113] Meanwhile, another embodiment of the supply unit 120 is, for example Figure 7 The system includes: a main body 121; a rotating shaft 122 formed on one side above the main body 121 toward the loading unit 110; a driving member 122a for rotating the rotating shaft 122; a moving member 124 configured to move in a front-rear direction in front of the rotating shaft 122; a locking member 124a configured to be rotatably mounted in front of the moving member 124 and threadedly engaged in front of the rotating shaft 122 so that the moving member 124 can be moved in a front-rear direction along the rotation direction; and a support body 12. 5. A side of the rotating shaft 122 is provided vertically on the middle side to support the belt A; a plurality of mounting portions 126 are formed radially on the outer side of the moving member 124 and are fixed to the inner diameter B of the belt A; a joint portion 127 connects the front of the moving member 124 and the front of the mounting portion 126; a rotating portion 128 connects the rear of the moving member 124 and the rear of the mounting portion 126; a linkage unit 129 is used to engage with the engaging member 124a on one side of the loading unit 110 and rotate therefrom.

[0114] In particular, the main body 121 may be formed with multiple unit bearings, etc., so that the rotating shaft 122 can be mounted at the upper front and rear and rotate smoothly.

[0115] Here, the rotating shaft 122 can be supplied by unwinding belt A while rotating forward or backward through the operation of the drive member 122a.

[0116] At this time, the drive component 122a can be used with a motor or a combination of a motor and a reducer, and can transmit driving force between the rotating shaft 122 and the drive component 122a by using sprockets, pulleys, chains and conveyor belts of various specifications.

[0117] On the other hand, a rotation measurement sensor 122b, such as an encoder, may be included at the rear end of the rotating shaft 122.

[0118] Furthermore, the threaded shaft 123 can move the threaded moving member 124 in the front-back direction along the rotation direction, thereby expanding or shrinking the plurality of mounting portions 126.

[0119] In addition, the drive component 123a can be used with a motor or a combination of a motor and a reducer, and can transmit driving force between the threaded shaft 123 and the drive component 123a using sprockets, pulleys, chains, and conveyor belts of various specifications.

[0120] Meanwhile, the moving shaft 123c can cause the moving member 124 to move in the front-back direction by the operation of the moving member 123d, thereby expanding or shrinking the plurality of mounting portions 126.

[0121] Here, the moving member 123d can be moved in the front-to-back direction by using a cylinder to move the moving shaft 123c.

[0122] In particular, the moving member 124 causes the joint portion 127 and the rotating portion 128 to rotate in the vertical direction by moving in the front-back direction, which can cause the mounting portion 126 to expand or shrink.

[0123] In addition, the support body 125 is supported on the other side of the vertically erected band A.

[0124] Furthermore, multiple mounting portions 126 can be arranged radially on the outer side of the movable member 124. When the movable member 124 moves backward in a state where the movable member 124 and the mounting portion 126 are connected by the joint portion 127 and the rotating portion 128, it expands while closely adhering to and fixing the inner diameter B of the belt A.

[0125] Here, the joint portion 127 and the rotating portion 128 support and guide so that the mounting portion 126 can move and rotate stably inward or outward.

[0126] At this time, the joint 127, the rotating part 128, the moving part 124, and the mounting part 126 can form a shaft or pin to rotate smoothly.

[0127] In this invention, the linkage unit 129 can be detached from the engaging member 124a, thereby expanding or shrinking the mounting portion 126 along the rotation direction.

[0128] Such a linkage unit 129 includes a support body 129a formed on one side of the lifting body 112 of the loading unit 110, a drive shaft 129b formed in the direction of the support body 129a toward the engaging member 124a, an engaging member 129c formed to engage with the engaging member 124a in front of the drive shaft 129b, a drive member 129d for rotating the drive shaft 129b, and an elastic body 129e formed between the drive shaft 129b and the engaging member 129c.

[0129] In particular, the linkage unit 129 moves simultaneously with the loading unit 110 as it transfers belt A to the supply unit 120, and the engaging member 129c engages with the engaging member 124a and rotates.

[0130] At this time, the drive shaft 129b can cause the engaging component 129c to rotate forward or backward through the operation of the drive member 129d, thereby causing the threaded moving member 124 to move in the front-back direction and causing the mounting part 126 to expand or shrink.

[0131] Here, the drive component 129d can be a motor or a combination of a motor and a reducer.

[0132] In addition, the elastomer 129e can use springs of various specifications and types to perform a buffering function during the engagement of the engaging member 129c and the engaging member 124a.

[0133] In this invention, the tension holding unit 130 performs the function of maintaining the tension of the passing band A while preventing slippage and kinking, thus ensuring smooth supply to the binding device.

[0134] Such a tension holding unit 130 includes: a main body 131; a front guide roller 132 formed on the upper side of the main body 131 so that the belt A received by the supply unit 120 can pass through; a plurality of intermediate guide rollers 133 formed in the middle of the upper part of the main body 131 so that the belt A can circulate and pass through; a rear guide roller 134 formed on the other side of the upper part of the main body 131 so that the belt A can pass through; a moving roller 135 formed to hold the tension of the belt A passing through while moving vertically in the middle of the main body 131; a front supply unit 136 for moving the belt A toward the front guide roller 132 on the front side of the main body 131; a rear supply unit 137 for moving the belt A toward the strapping device on the rear side of the main body 131; a front fixing unit 138 for fixing the belt A on the front side of the main body 131; and a rear fixing unit 139 for fixing the belt A on the rear side of the main body 131.

[0135] At this time, the tension holding unit 130 includes: a front auxiliary roller 131a, which guides the belt A received by the supply unit 120 toward the front guide roller 132 in front of and below the main body 131, and has a sensor 131c on the lower side for confirming the presence or absence of the belt A; and a rear auxiliary roller 131b, which guides the belt A toward the strapping device in the rear of and below the main body 131.

[0136] In particular, the sensor 131c can be a contact or non-contact sensor, thereby causing the front fixing unit 138 to operate by sensing the front end of the supplied belt A as it passes by, thus fixing the belt A in place and preventing problems such as detachment or tangling.

[0137] Here, by forming contact or non-contact sensing sensors 131d and 131e on the front and rear sides of the main body 131, the presence or movement of the belt A is confirmed, and the front fixing unit 138 and the rear fixing unit 139 are operated, so that the belt A can be fixed in its position to prevent the problem of detachment or tangling.

[0138] In addition, the front guide roller 132, the middle guide roller 133, and the rear guide roller 134 guide the belt A to pass through in a cyclic manner.

[0139] At this time, the front guide roller 132 guides the belt A to enter and circulate the moving roller 135, the middle guide roller 133 and the moving roller 135 form a plurality of guides to allow the belt A to circulate repeatedly in the up and down direction, and the rear guide roller 134 discharges the front end of the belt A circulating in the moving roller 135.

[0140] On the other hand, the moving roller 135 can be a structure with a certain weight to keep the circulating belt A pulled downwards at all times to maintain tension.

[0141] Here, the moving roller 135 can move smoothly in the vertical direction along the track 135a formed vertically in the middle of the body 131.

[0142] Meanwhile, the front supply unit 136, as a component for moving the front end of the belt A toward the front guide roller 132, includes a pressing roller 136a that is movable in the front-back direction, a drive roller 136b that is able to abut against the pressing roller 136a and rotate, and an auxiliary roller 136c formed below the drive roller 136b.

[0143] Therefore, with the contact roller 136a and the drive roller 136b in close contact with the belt A, the front end of the belt A can be moved by rotating the drive roller 136b.

[0144] At this time, the auxiliary rollers 136c are located on both sides of belt A to prevent them from detaching.

[0145] Additionally, the rear supply unit 137, as a component for moving the front end of the belt A toward the strapping device, includes a pressing roller 137a that is movable in the front-rear direction, a drive roller 137b that is able to abut against and rotate with the pressing roller 137a, and an auxiliary roller 137c formed above the drive roller 137b.

[0146] Therefore, with the contact roller 137a and the drive roller 137b in close contact with the belt A, the front end of the belt A can be moved by rotating the drive roller 137b.

[0147] At this time, the auxiliary rollers 137c are located on both sides of belt A to prevent them from detaching.

[0148] Here, a cylinder can be formed behind the contact rollers 136a and 137a to move in the front-back direction, and a motor can be formed on one side of the drive rollers 136b and 137b to rotate.

[0149] On the other hand, when the sensor 131c senses the front end of the moving belt A, the front fixing unit 138 and the rear fixing unit 139 can simultaneously fix the belt A to prevent the belt A from unwinding and detaching while the moving roller 135 is descending.

[0150] Here, the front fixing unit 138 and the rear fixing unit 139 include a pair of clamps for pressing and fixing the surface of the band A, and cylinders 138a and 139a for moving either of the pair of clamps in the front-rear direction.

[0151] In this invention, the belt guide unit 140 performs the following function: when supplying or replacing belt A, it sets up a path so that the front guide roller 132, the middle guide roller 133, the rear guide roller 134 and the moving roller 135 can be circulated naturally without the need for operators.

[0152] The guide unit 140 includes a front cover 132a formed to surround the outer side of the front guide roller 132 and configured to be open at the bottom, a middle cover 133a formed to surround the outer side of the middle guide roller 133 and configured to be open at the bottom, a rear cover 134a formed to surround the outer side of the rear guide roller 134 and configured to be open at the bottom, a guide cover 142 formed to surround the outer side of the moving roller 135 with the moving roller 135 placed inside and configured to be open at the top, and a drive member 141 for moving the guide cover 142 in the vertical direction.

[0153] Here, when the front cover 132a, the middle cover 133a, and the rear cover 134a are formed such that band A surrounds the outer side of the front guide roller 132, the middle guide roller 133, and the rear guide roller 134 and is configured to be open at the bottom, and the guide cover 142 is formed such that band A surrounds the outer side of the moving roller 135 and is configured to be open at the top, and when the lower part of the front cover 132a, the middle cover 133a, and the rear cover 134a and the upper part of the guide cover 142 abut against each other, it can prevent band A from detaching to the outside, thus forming a natural circulation and movement path.

[0154] In particular, with the movable roller 135 positioned inside the guide cover 142, the drive member 141 is guided to move upward by operation so that belt A can circulate the front guide roller 132, the middle guide roller 133, the rear guide roller 134, and the movable roller 135.

[0155] Here, the intermediate cover 133a and the guide cover 142 are formed to be inclined from one side to the other so that the belt A can be circulated in a threaded manner through the intermediate guide roller 133 and the moving roller 135.

[0156] Additionally, when the guide cover 142 moves downward, the moving roller 135 can move in the vertical direction to maintain the tension of belt A.

[0157] At this time, the drive component 141 can be combined with various specifications and types of cylinders or threaded shafts and motors.

[0158] On the other hand, such as Figure 8As shown, it may include a coupling unit 150 for continuously supplying the back end of the used belt and the front end of a new belt by coupling them together between the supply unit 120 and the tension holding unit 130.

[0159] Here, the joining unit 150 includes a support body 151 supported on top for overlapping the front end of the band A, a fastener 152 for fixing the front end of the band A above the support body 151, electrodes 154 and 155 formed to be welded to the front end of the band A above and below the middle of the support body 151, and a cylinder 153 for moving the electrode 154 in the vertical direction.

[0160] Therefore, with the two sides of the strip A fixed by the fastener 152, the electrodes 154 and 155 supply current to perform spot welding in a state where the front ends of the strip A overlap.

[0161] In particular, the electrodes 154 and 155 weld the two points together to be spaced apart in the width direction of the band A. The joined band A moves toward the tension holding unit 130. After the band A is fixed by the rear fixing unit 139, the overlapping part of the joined band A is cut by a separate cutting device, and the front end of the cut band A is supplied to the binding device.

[0162] Therefore, in this invention, as Figure 8 as well as Figure 9 As shown, a crane 160 with various forms and structures is used to move the coil-wound belt A to the loading unit 110 and load it on the loading section 114 in a vertically upright state.

[0163] At this time, as Figure 10 As shown, the lifting body 112 is moved vertically to adjust its height so that the mounting part 126 can be inserted into the inner diameter B of the section A.

[0164] And, as Figure 11 As shown, the loading unit 110 is moved toward the supply unit 120 and guided so that the mounting part 126 can be inserted into the inner diameter B of the belt A.

[0165] Next, as Figure 12 As shown, after the inner diameter B of the belt A is fixed while the mounting part 126 expands, the loading unit 110 returns to the initial position.

[0166] On the other hand, such as Figure 13As shown, the supply unit 120 supplies the front end of belt A to the tension holding unit 130, and the front end of belt A maintains tension while circulating sequentially through the front guide roller 132, the middle guide roller 133, the rear guide roller 134 and the moving roller 135, and moves toward the strapping device.

[0167] Here, by operating the drive member 141, the guide cover 142 moves upward and remains in contact with the lower part of the front cover 132a, the middle cover 133a, and the rear cover 134a, thereby forming a passage through which the moving belt A can circulate naturally without detaching from the outside.

[0168] In particular, the operation of the belt guide unit 140 can eliminate the inconvenience and complexity of the operator having to manually grasp the front end of the belt A and circulate the front guide roller 132, the middle guide roller 133, the rear guide roller 134 and the moving roller 135.

[0169] Finally, as Figure 14 As shown, the guide cover 142 moves downward, and the moving roller 135 moves in the vertical direction according to the supply speed of belt A, etc., while smoothly supplying the strapping device with belt A under tension.

[0170] Thus, the embodiments of the present invention have been described in detail above, but the scope of the present invention is not limited thereto, and any scope substantially equivalent to the embodiments of the present invention is also included in the scope of the present invention.
