The present disclosure relates to strap-winding and strap-coil-deforming systems.
Steel, aluminum, and other metals are manufactured into (relatively) thin sheets that are wound into large, heavy coils for storage and (later) transport to customers. To prevent one of these metal coils from uncoiling, its manufacturer typically applies several segments of steel strap around the circumference of the coil and, occasionally, through the “eye” of the coil. After a customer receives the coil, it must remove and dispose of the strap segments before using the coil. One can use a strap-removal robot-sometimes referred to as a “debander”—to cut the strap segments from the coil and to deliver them to a winder. The winder winds the strap segments into coils, which the customer then disposes of or recycles. While the strap coils are more compact and easier to handle, store, and transport than long segments of flexible steel strap, there's a chance they can uncoil during handling, storage, or transport.
Various embodiments of the present disclosure provide a strap-winding and strap-coil-deforming system configured to wind a strap segment into a coil and then deform the strap coil to render it more compact and to reduce the likelihood that it will uncoil during handling, storage, or transport. The deformed strap coil is introduced into a discharge chute to discharge it away from the strap-winding and strap-coil-deforming system for further handling, storage, or transport.
One embodiment of the strap-winding and strap-coil-deforming system of the present disclosure comprises a containment wall; first, second, and third gates movable between respective open positions and respective closed positions; first and second deformers comprising first and second deforming surfaces, wherein the first and second deformers are movable between respective retracted positions and deforming positions; and a winding assembly comprising a winding-assembly carriage supporting a rotatable winding head comprising multiple winding fingers, wherein the winding-assembly carriage is movable between a collecting position and a winding position, wherein the winding head is movable between a retracted position and a winding position. The containment wall, the first and second gates, and the first deforming surface of the first deformer at least partially define a first deforming chamber. The containment wall, the second and third gates, and the second deforming wall of the second deformer at least partially define a second deforming chamber.
One embodiment of a strap-winding and strap-coil-deforming process of the present disclosure comprises: rotating a winding head to wind a strap segment into a coil; deforming the strap coil in a first deforming chamber; and after the deformed strap coil has moved from the first deforming chamber into a second deforming chamber, further deforming the strap coil in the second deforming chamber.

Various embodiments of the present disclosure provide a strap-winding and strap-coil-deforming system configured to wind a strap segment into a coil and then deform the strap coil to render it more compact and to reduce the likelihood that it will uncoil during handling, storage, or transport. The deformed strap coil is introduced into a discharge chute to discharge it away from the strap-winding and strap-coil-deforming system for further handling, storage, or transport.

The controller 900 includes a processing device (or devices) communicatively connected to a memory device (or devices). For instance, the controller may include a programmable logic controller. The processing device may include any suitable processing device such as, but not limited to, a general-purpose processor, a special-purpose processor, a digital-signal processor, one or more microprocessors, one or more microprocessors in association with a digital-signal processor core, one or more application-specific integrated circuits, one or more field-programmable gate array circuits, one or more integrated circuits, and/or a state machine.

The memory device stores instructions executable by the processing device to control operation of the system 10 (such as to carry out the strap-winding and strap-coil-deforming process 800 described below with respect to
As shown in
Operation of the system 10 to carry out a strap-winding and strap-coil-deforming process 800 for a strap segment S is now described in conjunction with
After part of a strap segment is positioned in the strap-receiving channel of the strap-winding and strap-coil-deforming system, as block 802 indicates, the strap clamps clamp the strap segment in place, as block 804 indicates. For instance, referring to the example embodiment described above and shown in the Figures, the controller 900 controls the clamp actuator 260 to move the first and second strap clamps 240 and 250 from their respective strap-insertion positions to their respective strap-clamp positions. As the first and second strap clamps 240 and 250 reach their respective strap-clamp positions, the roller 244 of the first strap clamp 240 forces part of the strap segment S onto the clamping surface of the backstop 120, and the roller 254 of the second strap clamp 250 forces another part of the strap segment S onto the clamping surface of the first (upper) deformer guide 130a to hold the strap segment S in place.
With the winding assembly in its collecting position, the winding head extends so its winding fingers flank part of the strap segment extending between the strap clamps, as block 806 indicates. Continuing with the above example, the controller 900 controls the second winder actuator 490b to move the winding-head carriage 440 from its retracted position to its winding position such that, as shown in
The winding assembly moves to its winding position, causing the winding head to pull the part of the strap segment with it, as block 808 indicates, and the upper and middle gates close to enclose part of the winding fingers and the part of the strap segment pulled with the winding fingers in the first deforming chamber, as block 810 indicates. Continuing with the above example, the controller 900 controls the first winder actuator 490a to move the winding-assembly carriage 410 from its collecting position to its winding position. As this occurs, the underside of the first winding finger 464 contacts the strap segment S and pulls the strap segment S downward with the winding head 460. The rollers 244 and 254 of the first and second strap clamps 240 and 250 enable the winding head 460 to pull the strap segment S with it while the strap clamps maintain clamping pressure on the strap segment S. The controller 900 controls the first gate actuator 191 to move the first (upper) and second (middle) gates 160 and 170 from their respective open positions to their respective closed positions. As shown in
The winding head winds the strap segment into a coil, as block 812 indicates, and then retracts to remove the winding fingers from the first deforming chamber, as block 814 indicates. Continuing with the above example, the controller 900 controls the third winder actuator 490c to rotate the winding head 460, as shown in
The first deformer deforms the strap coil, as block 816 indicates. Continuing with the above example, the controller 900 controls the first deformer actuator 320 to move the first deformer 310 from its retracted position to its deforming position. As the first deformer 310 moves, its first deforming surface 310a contacts the strap coil C and forces the strap coil C against the first deforming surface 120a of the backstop 120. Continued movement of the first deformer 310 causes the first deformer 310 to deform the strap coil C into an oblong shape, as shown in
The upper and middle gates open to enable the deformed strap coil to fall out of the first deforming chamber and onto the closed bottom gate, as block 818 indicates, and the upper and middle gates close to enclose the deformed strap coil in the second deforming chamber, as block 820 indicates. Continuing with the above example, the controller 900 controls the first deformer actuator 320 to move the first deformer from its deforming position to its retracted position and also controls the first gate actuator 191 to move the first (upper) and second (middle) gates from their respective closed positions to their respective open positions. As this occurs, the deformed strap coil C falls out of the first deforming chamber 100a and into the second deforming chamber 100b before coming to a stop atop the third (lower) gate 180. The controller 900 controls the first gate actuator 191 to move the first (upper) and second (middle) gates 160 and 170 from their respective open positions to their respective closed positions to enclose the deformed strap coil in the second deforming chamber 100b, as shown in
The second deformer further deforms the deformed strap coil, as block 822 indicates. Continuing with the above example, the controller 900 controls the second deformer actuator 340 to move the second deformer 330 from its retracted position to its deforming position. As the second deformer 330 moves, its second deforming surface 330a contacts the deformed strap coil C and forces the deformed strap coil C against the second deforming surface 120b of the backstop 120. Continued movement of the first deformer 310 causes the projections 330al and 330a2 of the second deforming surface 330a to form notches in the deformed strap coil C. These notches further deform the deformed strap coil C and cause it to further resist uncoiling. Thus, in this example embodiment: the first deformer causes a first type of deformation by deforming the strap coil into an oblong shape, and the second deformer causes a second, different type of deformation by forming notches into the oblong strap coil.
The bottom gate opens to enable the deformed strap coil to fall out of the second deforming chamber and into the discharge chute, as block 824 indicates. Continuing with the above example, the controller 900 controls the second deformer actuator 340 to move the second deformer 330 from its deforming position to its retracted position and controls the second gate actuator 192 to move the third (lower) gate 180 from its closed position to its open position. This enables the deformed strap coil C to fall out of the second deforming chamber 100b and into the discharge chute DC, as shown in
For clarity, during the winding and deforming process: the first (upper), second (middle), and third (lower) gates and the winding-head carriage move back and forth in a first direction (the Z-direction in the above example embodiment); the first and second deformers move back and forth in a second direction (the X-direction in the above example embodiment); and the winding-assembly carriage moves back and forth in a third direction (the Y-direction in the above example embodiment). The first, second, and third directions are transverse to (and in the above example embodiment, perpendicular to) one another. The first (upper), second (middle), and third (lower) gates are movable relative to the winding-head carriage, the first and second deformers, and the winding-assembly carriage. The winding-head carriage is movable relative to the first (upper), second (middle), and third (lower) gates; the first and second deformers; and the winding-assembly carriage. The first and second deformers are movable relative to the first (upper), second (middle), and third (lower) gates; the winding-assembly carriage; and the winding-head carriage. The winding-assembly carriage is movable relative to the first (upper), second (middle), and third (lower) gates; the winding-head carriage; and the first and second deformers.
In the embodiment of the deforming assembly described above and shown in the Figures, the deforming assembly includes two deformers. In other embodiments, the deforming assembly includes first and second upper deformers and first and second lower deformers. First and second upper deformer actuators are operably connected to the first and second upper deformers, respectively, to control movement of the first and second upper deformers. Similarly, first and second lower deformer actuators are operably connected to the first and second lower deformers, respectively, to control movement of the first and second lower deformers. In these embodiments, the system does not include a backstop. Rather, the first deforming chamber is defined by the first (upper) and second (middle) gates, the first and second upper deformers, and the first and second containment walls. Similarly, the second deforming chamber is defined by the second (middle) and third (lower) gates, the first and second lower deformers, and the first and second containment walls. In these embodiments, to deform the strap coil in the first deforming chamber, the first and second upper deformer actuators control the first and second upper deformers to move toward one another to engage and deform the strap coil. Similarly, to deform the deformed strap coil in the second deforming chamber, the first and second lower deformer actuators control the first and second lower deformers to move toward one another to engage and deform the strap coil.
In the embodiment of the deforming assembly described above and shown in the Figures, the winding assembly winds the strap segment into a coil within the first deforming chamber. In other embodiments, the winding assembly winds the strap segment into a coil outside of or partially inside of the first deforming chamber and then moves the strap coil into the first deforming chamber in preparation for deforming.
In certain embodiments, both deformers include projections, while in other embodiments neither deformer includes projections.
The frame F, the housing H, the strap guides G, and the discharge chute DC are similar to (or the same as) those described above with respect to the system 10 and are thus not separately described here. The gate assembly 1100, the clamping assembly 1200, and the deforming assembly 1300 are similar to the gate assembly 100, the clamping assembly 200, and the deforming assembly 300 described above with respect to the system 10 and are thus not separately described here. Components of the gate assembly 1100, the clamping assembly 1200, and the deforming assembly 1300 are identified below with the same numbering convention used for their counterparts in the gate assembly 100, the clamping assembly 200, and the deforming assembly 300 with the addition of a “1” before the element number. For instance, the first gate actuator of the gate assembly 1100 is identified as element number 1191.

The second (lower) ejecting assembly 1490 helps move the deformed strap coil from the second deforming chamber 1100b to the discharge chute DC (if needed). As best shown in
The second (lower) ejecting assembly actuator 1494 is operably connected to the third ejecting finger 1496, which is a pin in this example embodiment (but may be any other suitable component in other embodiments), and configured to move the third ejecting finger 1496 in the Z-direction between a retracted position (
The straightening assembly 1500, which is shown in
Operation of the system 1000 to carry out a strap-winding and strap-coil-deforming process for a strap segment S is now described. Initially: the first (upper) gate 1160 and the second (middle) gate 1170 of the gate assembly 1100 are in their respective open positions; the third (lower) gate 1180 of the gate assembly 1100 is in its closed position; the first and second strap clamps 1240 and 1250 of the clamping assembly 1200 are in their respective strap-insertion positions; the first and second deformers 1310 and 1330 of the deforming assembly 1300 are in their respective retracted positions; the winding-assembly carriage 1410 is in its collecting position; the winding-head carriage 1440 is in its retracted position; the winding head 1460 is in its home (rotational) position, the first, second, and third ejecting fingers 1486a, 1486b, and 1496 are in their retracted positions; and the second roller 1520 is in its open position.
After part of a strap segment is positioned in the strap-receiving channel SC of the strap-winding and strap-coil-deforming system 1000, the controller 1900 controls: (1) the clamp actuator 1260 to move the first and second strap clamps 1240 and 1250 from their respective strap-insertion positions to their respective strap-clamp positions; and (2) the straightening-assembly actuator 1530 to move the second roller 1520 to its closed position. As the first and second strap clamps 1240 and 1250 reach their respective strap-clamp positions, the roller 1244 of the first strap clamp 1240 forces part of the strap segment S onto the clamping surface of the backstop 1120, and the roller 1254 of the second strap clamp 1250 forces another part of the strap segment S onto the clamping surface of the first (upper) deformer guide 1130a to hold the strap segment S in place. And as the second roller 1520 reaches its closed position, it forces the strap segment S against the first roller 1510, pinching it between the first and second rollers.
The controller 1900 controls the second winder actuator 1490b to move the winding-head carriage 1440 from its retracted position to its winding position such that the first and second winding fingers 1464 and 1466 of the winding head 1460 flank part of the strap segment S that extends between the first and second strap clamps 1240 and 1250. The controller 1900 controls the first winder actuator 1490a to move the winding-assembly carriage 1410 from its collecting position to its winding position. As this occurs, the underside of the first winding finger 1464 contacts the strap segment S and pulls the strap segment S downward with the winding head 1460. The rollers 1244 and 1254 of the first and second strap clamps 1240 and 1250 enable the winding head 1460 to pull the strap segment S with it while the strap clamps maintain clamping pressure on the strap segment S. The controller 1900 controls the first gate actuator 1191 to move the first (upper) and second (middle) gates 1160 and 1170 from their respective open positions to their respective closed positions. This encloses the portions of the first and second winding fingers 1464 and 1466 projecting from the winding-assembly carriage 1410 and part of the strap segment S in the first deforming chamber 1100a.
The controller 1900 controls the third winder actuator 1490c to rotate the winding head 1460. As this occurs, the remainder of the strap segment S is pulled through the rollers 1510 and 1520 of the strap-straightening assembly 1500, into the first deforming chamber 1100a, and wound into a strap coil C. As the strap segment moves between the rollers 1510 and 1520, they remove (or lessen) any curl in the strap segment to facilitate winding into the coil. Additionally, as the strap segment moves between the rollers 1510 and 1520, it causes the rollers to rotate, and the sensor 1540 detects this rotation. Once the strap segment S has been completely wound into the strap coil, it no longer contacts the rollers 1510 and 1520, and the rollers stop rotating. The sensor 1540 detects this and generates and sends a corresponding signal to the controller 1900. In response to receiving this signal, the controller 1900 controls the third winder actuator 1490c to stop rotating the winding head 1640. The controller 1900 controls the second winder actuator 1490b to move the winding-head carriage 1440 from its winding position to its retracted position such that the first and second winding fingers 1464 and 1466 are removed from the first deforming chamber 1100a (and no longer contact the strap coil C).
The controller 1900 controls the first deformer actuator 1320 to move the first deformer 1310 from its retracted position to its deforming position. As the first deformer 1310 moves, its first deforming surface 1310a contacts the strap coil C and forces the strap coil C against the first deforming surface 1120a of the backstop 1120. Continued movement of the first deformer 1310 causes the first deformer 1310 to deform the strap coil C into an oblong shape.
The controller 1900 controls the first deformer actuator 1320 to move the first deformer from its deforming position to its retracted position and also controls the first gate actuator 1191 to move the first (upper) and second (middle) gates from their respective closed positions to their respective open positions. As this occurs, in most cases the deformed strap coil C falls out of the first deforming chamber 1100a and into the second deforming chamber 1100b before coming to a stop atop the third (lower) gate 1180. But in certain instances the deformed strap coil C becomes stuck in the first deforming chamber 1100a or between the first and second deforming chambers 1100a and 1100b. To ensure the deformed strap coil C reaches the second deforming chamber 1100b, the controller 1900 controls the first winder actuator 1490a to move the winding-assembly carriage 1410 from its winding position to its collecting position (or another position above the winding position). The controller 1900 controls the first (upper) ejecting assembly actuator 1484 to move the first and second ejecting fingers 1486a and 1486b from their retracted positions to their ejecting positions. The controller 1900 then controls the first winder actuator 1490a to move the winding-assembly carriage 1410 from its collecting position toward the second deforming chamber 1100b. As this occurs, if the deformed strap coil C is stuck one or both of the first and second ejecting fingers 1486a and 1486b contact and force the deformed strap coil C to move into the second deforming chamber 1100b. The controller 1900 then controls the first (upper) ejecting assembly actuator 1484 to move the first and second ejecting fingers 1486a and 1486b from their ejecting positions to their retracted positions and the first winder actuator 1490a to move the winding-assembly carriage 1410 back to its collecting position.
The controller 1900 controls the first gate actuator 1191 to move the first (upper) and second (middle) gates 1160 and 1170 from their respective open positions to their respective closed positions to enclose the deformed strap coil in the second deforming chamber 1100b. The controller 1900 controls the second deformer actuator 1340 to move the second deformer 1330 from its retracted position to its deforming position. As the second deformer 1330 moves, its second deforming surface 1330a contacts the deformed strap coil C and forces the deformed strap coil C against the second deforming surface 1120b of the backstop 1120. Continued movement of the first deformer 1310 causes the projections 1330a1 and 1330a2 of the second deforming surface 1330a to form notches in the deformed strap coil C. These notches further deform the deformed strap coil C and cause it to further resist uncoiling. Thus, in this example embodiment: the first deformer causes a first type of deformation by deforming the strap coil into an oblong shape, and the second deformer causes a second, different type of deformation by forming notches into the oblong strap coil.
The controller 1900 controls the second deformer actuator 1340 to move the second deformer 1330 from its deforming position to its retracted position and controls the second gate actuator 1192 to move the third (lower) gate 1180 from its closed position to its open position. This enables the deformed strap coil C to fall out of the second deforming chamber 1100b and into the discharge chute DC. But in certain instances the deformed strap coil C becomes stuck in the second deforming chamber 1100b or between the second deforming chamber 1100b and the discharge chute DC. To ensure the deformed strap coil C reaches the discharge chute DC, the controller 1900 controls the second (lower) ejecting assembly actuator 1494 to move the third ejecting finger 1496 from its retracted position to its ejecting position. The controller 1900 then controls the first winder actuator 1490a to move the winding-assembly carriage 1410 from its collecting position toward the discharge chute DC. As this occurs, if the deformed strap coil C is stuck the third ejecting finger 1496 contacts and forces the deformed strap coil C to move into the discharge chute DC. The controller 1900 then controls the second (lower) ejecting assembly actuator 1494 to move the third ejecting finger 1496 from its ejecting position to its retracted position and the first winder actuator 1490a to move the winding-assembly carriage 1410 back to its collecting position.
