Detailed Implementation Manner

[0034] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and should not be construed as a limitation to the present application.

[0035] In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0036] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0037] In the present application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected to", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0038] In this application, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply indicates that the first feature has a lower horizontal height than the second feature.

[0039] The reinforcing bar raw materials generally come in whole bundles, with a specification of Φ12 - 40mm and a length of 6 - 12m. During actual use, the reinforcing bars need to be picked up according to requirements and fed into a cutting device to be cut into the required length. When picking up the reinforcing bars, first place the reinforcing bars in the feeding bin.

[0040] When a certain specification of reinforcing bars in the feeding bin is used up, it is necessary to stop the machine for feeding. The operator needs to coordinate the on-site tower crane or other lifting equipment to hoist the reinforcing bars of each specification to the designated bin and untie the bundled steel wire ropes, and then the operation can be resumed. Such a feeding operation requires the production line to stop and wait for the feeding to be completed before starting production again. The scheduling of the on-site tower crane equipment is uncertain, resulting in the feeding waiting time being difficult to predict, which seriously affects the processing progress. Other lifting equipment such as a truck crane can also be used exclusively for the reinforcing bar processing production line, but this greatly increases the processing cost.

[0041] In response to the above problems, as Figure 1 shown, an embodiment of the present application provides a feeding device 100, which is mainly used to reduce the shutdown frequency of the reinforcing bar processing production line and speed up the progress of the reinforcing bar processing operation. The feeding device 100 includes a buffer storage rack 110 and a feeding truss 120. The buffer storage rack 110 is used to store the reinforcing bar materials to be processed, and the feeding truss 120 is used to hoist and move the materials stored in the buffer storage rack 110 to the feeding bin 210.

[0042] The buffer storage rack 110 is used to store the reinforcing bar materials with a specification of Φ12 - 40mm and a length of 6 - 12m, and the storage space of the buffer storage rack 110 is larger than the space of the feeding bin 210, so as to be able to timely and sufficiently supplement the materials in the feeding bin 210 when the materials in the feeding bin 210 are about to be exhausted.

[0043] As Figure 2 shown, the buffer storage rack 110 is provided with a plurality of storage bins 111, the storage bins 111 are arranged along the first direction D1, and the plurality of storage bins 111 are arranged in parallel along the second direction D2.

[0044] A tower crane or other hoisting equipment hoists bundled steel bar materials of various specifications to the buffer rack 110 and places them in the storage bin 111. The storage bin 111 is arranged along the first direction D1. In other words, the storage bin 111 is arranged along the length direction of the steel bars. The length of the storage bin 111 is 8 to 12 meters, which is convenient for storing materials with a length of 6 to 12 meters. At the same time, the length of the storage bin 111 is limited to reduce the floor area.

[0045] When the steel bar materials are placed in the storage bin 111, the ties of the steel bar materials are untied so that the steel bars of the same specification are stacked in one storage bin 111, avoiding the mixing of steel bars of different specifications in different storage bins 111.

[0046] As Figure 3 shown, the feeding truss 120 includes two support frames 123, a moving frame 122 and a picking mechanism 121. Among them, the two support frames 123 are arranged at intervals along the first direction D1, the buffer rack 110 is arranged between the two support frames 123, the moving frame 122 is mounted on the two support frames 123 and moves along the second direction D2, and the picking mechanism 121 is movably arranged on the moving frame 122 and moves along the first direction D1 or the third direction D3 to pick up the materials in the storage bin 111. In this way, the picking mechanism 121 moves along the second direction D2 to the position of the storage bin 111 of the required specification of steel bar materials, moves along the third direction D3 to pick up the required specification of steel bar materials, and then moves along the second direction D2 or the third direction D3 to move the steel bar materials into the corresponding feeding bin 210, timely replenishing the steel bar materials in the feeding bin 210. The steel bar processing production line does not need to stop, greatly improving the operation efficiency of the production line and accelerating the processing progress of the production line.

[0047] It should be noted that the first direction D1 is the length direction of the steel bars, the third direction D3 is the height direction relative to the ground, and the first direction D1, the second direction D2 and the third direction D3 are perpendicular to each other in pairs.

[0048] In some embodiments, as Figure 3 shown, the moving frame 122 includes a cross beam 1221 and two end beams 1222.

[0049] The cross beam 1221 is erected above the two support frames 123 and arranged along the first direction D1. The end beams 1222 are connected to the ends of the cross beam 1221 and are movably connected to the support frames 123, so that the cross beam 1221 can drive the picking mechanism 121 to move along the first direction D1 and the second direction D2. In this way, it is convenient to quickly move the picking mechanism 121 to the position of the storage bin 111 of the material to be picked up.

[0050] In some embodiments, the moving frame 122 further includes a first slide rail (not shown in the figure) and a slider (not shown in the figure). The first slide rail is provided on the cross beam 1221, the slider is slidably provided on the first slide rail, and the picking mechanism 121 is connected to the slider, so that the picking mechanism 121 is movably provided on the first slide rail.

[0051] In one embodiment, a linear motor or a stepper motor drives the slider to move on the first slide rail through a transmission mechanism (such as a belt, a chain, a gear, etc.). Combining with sensors (such as photoelectric sensors, proximity switches, etc.) and a controller (such as a programmable logic controller, a single-chip microcomputer, etc.), precise control of the position and speed of the slider is achieved, and the picking mechanism 121 is moved and positioned along the first direction D1.

[0052] The picking mechanism 121 includes clamping jaws, and the clamping jaws move along the third direction D3. In one embodiment, the picking mechanism 121 uses an electric hoist or a mechanical clamping jaw. An electric hoist is a lifting device driven by a motor, usually including components such as a motor, a reducer, a drum, a steel wire rope or a chain, etc., for lifting and lowering heavy objects. A mechanical clamping jaw is a device for grasping and releasing objects, usually driven by pneumatic, hydraulic or electric means, and is suitable for various shapes and sizes of items.

[0053] The number of the picking mechanisms 121 is at least two, and the corresponding number of picking mechanisms 121 is called according to the length of the steel bar material to be picked.

[0054] In some embodiments, as Figure 3 shown, the support frame 123 includes a longitudinal beam 1231 and a support beam 1233.

[0055] The longitudinal beam 1231 is arranged along the second direction D2, a second slide rail 1232 is provided on the longitudinal beam 1231, and the end beam 1222 is movably arranged on the second slide rail 1232.

[0056] In one embodiment, the end beam 1222 includes a motor and rollers. The rollers roll along the second slide rail 1232 to drive the end beam 1222 and the cross beam 1221 to move along the first direction D1. By outputting torque from a brushless motor or a stepper motor, passing through a reducer and a transmission mechanism (such as a belt, a gear, etc.), the power is transmitted to the rollers, thereby realizing the rotational movement of the rollers. The motor is installed on the cross beam 1221 or the end beam 1222.

[0057] The support beam 1233 is arranged along the third direction D3 and is connected to the side of the longitudinal beam 1231 away from the end beam 1222. The support beam 1233 is arranged below the longitudinal beam 1231 to support the cross beam 1221. As Figure 3 shown, the bottom of the cross beam 1221 has a triangular structure, which improves the stability of the support beam 1233 and reduces the vibration of the steel bar material during transportation.

[0058] In some embodiments, the support frame 123 further includes a first reinforcing rib 1234. The first reinforcing rib 1234 connects the longitudinal beam 1231 and the support beam 1233, and the first reinforcing rib 1234, the support beam 1233 and the longitudinal beam 1231 are connected to form a triangular structure.

[0059] As Figure 3 shown, the number of the first reinforcing ribs 1234 is two. The first reinforcing ribs 1234 are used to support the end of the longitudinal beam 1231, improving the stability and load-bearing capacity of the support frame 123.

[0060] In some embodiments, the number of the support beams 1233 is two. The two support beams 1233 are arranged at intervals along the second direction D2. The support frame 123 further includes at least one second reinforcing rib 1235. The at least one second reinforcing rib 1235 is arranged at intervals along the third direction D3. The second reinforcing rib 1235 connects the two support beams 1233.

[0061] As Figure 3 shown, the longitudinal beam 1231 and the two support beams 1233 are connected to form a gantry structure. The loading truss 120 of the gantry structure can provide stable support and a moving platform. Combined with an electric hoist and a mechanical gripper, more efficient material handling and processing can be achieved.

[0062] In some embodiments, the buffer rack 110 includes a moving base 113 and a plurality of partition members 112. The plurality of partition members 112 are arranged in an array to form a plurality of bins.

[0063] In one embodiment, as Figure 2 shown, the moving base 113 is a steel frame formed by welding steel. The partition members 112 are steel bars welded to the steel frame. The plurality of steel bars are arranged in an array. Such a simple structure can meet the usage requirements for storing steel bar materials and can also reduce the manufacturing difficulty and cost of the buffer rack 110.

[0064] In one embodiment, rollers are installed at the bottom of the moving base 113, facilitating the dragging of the buffer rack 110 by an automobile or moving the buffer rack 110 to the lower part of the moving rack 122.

[0065] The present application provides a loading system 1000, including the loading device 100 and the conveying rack 200 in any one of the foregoing embodiments. The conveying rack 200 is used to feed the steel bar materials into a cutting device to be cut into required lengths.

[0066] The conveying rack 200 is provided with a plurality of feeding bins 210. The feeding bins 210 are arranged along the first direction D1. The feeding bins 210 are arranged in parallel with the storage bins 111. The loading truss 120 does not need to adjust the angle of the steel bar materials, improving the transportation efficiency of the loading truss 120.

[0067] A plurality of feeding bins 210 are arranged along the second direction D2, facilitating the separate placement of reinforcing bar materials of multiple specifications.

[0068] The buffer rack 110 and the conveying rack 200 are arranged at intervals along the second direction D2, and the loading truss 120 is arranged between the buffer rack 110 and the conveying rack 200. The picking mechanism 121 is driven by the loading truss 120 to move along the second direction D2 to the position of the storage bin 111 of the reinforcing bar material of the required specification, move along the third direction D3 to pick up the reinforcing bar material of the required specification, and then move along the second direction D2 or the third direction D3 to move the reinforcing bar material into the corresponding feeding bin 210, timely supplementing the reinforcing bar material in the feeding bin 210. The reinforcing bar processing production line does not need to stop, greatly improving the operation efficiency of the production line and accelerating the processing progress of the production line.

[0069] In some embodiments, the loading system 1000 further includes a moving mechanism 300, and the moving mechanism 300 is connected to the conveying rack 200 and drives the conveying rack 200 to move along the second direction D2.

[0070] As Figure 1 shown, the inlet position of the cutting device is fixed. By moving the moving mechanism 300 and driving the conveying rack 200 to move along the second direction D2, the outlet of the feeding bin 210 where the reinforcing bar material to be cut is located is aligned with the inlet of the cutting device. In this way, when the reinforcing bar material in the previous feeding bin 210 is exhausted, the moving mechanism 300 moves the conveying rack 200 to continuously convey the reinforcing bar material in the next feeding bin 210 to the cutting device. The reinforcing bar processing production line does not need to stop, greatly improving the operation efficiency of the production line and accelerating the processing progress of the production line.

[0071] As Figure 1 and Figure 4 shown, the present application provides a loading method, which is implemented by using the loading system 1000 of the foregoing embodiments, including:

[0072] Step S10, transporting the material to the storage bin 111 of the buffer rack 110 and the feeding bin 210 on the conveying rack 200.

[0073] Before the reinforcing bar processing production line is started, the operator needs to coordinate the on-site tower crane or other lifting equipment to hoist the reinforcing bar materials of each specification to the feeding bin 210 of the conveying rack 200 and untie the straps of the reinforcing bar materials. When the reinforcing bar processing production line is started and during the production process, the operator also hoists the reinforcing bar materials of each specification to the storage bin 111 of the buffer rack 110 and untie the straps of the reinforcing bar materials. This enables one hoisting operation to carry more reinforcing bar materials, reducing the hoisting frequency of the tower crane equipment and reducing costs.

[0074] Step S20: When the materials in the feeding bin 210 need to be replenished, the loading truss 120 moves the materials in the bin to the feeding bin 210.

[0075] Specifically, the loading truss 120 transports the materials to the idle feeding bin 210. For example, when the steel bar materials with a diameter of 12 mm and a length of 6 meters are about to be consumed, the loading truss 120 transports the materials of the same specification to the idle feeding bin 210. After the materials in the previous feeding bin 210 are consumed, the moving mechanism 300 moves the conveying rack 200 to align the outlet of the newly filled feeding bin 210 with the inlet of the cutting device, shortening the feeding time of the cutting device and improving the operation efficiency of the steel bar processing production line.

[0076] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples", etc. means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application.

In addition, without conflict, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.
