[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] like Figure 1 As shown, the shearing machine with a material transport device in an embodiment of the present invention includes a main body (not shown in the figure) and a material transport device 100, the main body has a material discharge port, the material transport device 100 includes a frame 1 and a plurality of material transport carts 2, the frame 1 has a material receiving area 11 arranged at the lower side of the material discharge port, the material transport cart 2 has a material receiving portion 21 for receiving the material plate, the material transport cart 2 is movably connected to the frame 1, and the plurality of material transport carts 2 move alternately to the material receiving area 11.

[0032] In the plate shearing machine with the anticipation device of the embodiment of the present invention, the material transport cart 2 can move to the material receiving area 11, and the material plate after the plate shearing machine shears and unloads the material falls on the material receiving part 21 of the material transport cart 2. After the material plates on the material transport cart 2 are accumulated to a certain number, the fully loaded material transport cart 2 can be controlled to move outwards, and the material plates can be moved to the outside of the plate shearing machine. The operator does not need to drill under the plate shearing machine to take out the material plates, which is more convenient to operate, thereby improving the safety of operation. At the same time, since multiple material transport carts 2 can be moved alternately to the material receiving area 11, when the fully loaded material transport cart 2 moves outwards, the unloaded material transport cart 2 can be synchronously moved to the material receiving area 11 for receiving the material, so as to ensure the continuity of receiving the material, and there is no need to stop the machine during the material taking period, thereby improving the operation efficiency of the plate shearing machine.

[0033] As an example, Figure 1 As shown, the material transport cart 2 has a rectangular material receiving cavity, which forms the above-mentioned material receiving portion 21; the frame 1 is in the shape of a long strip and is welded from profiles, the material receiving area 11 is arranged at one end of the length direction of the frame 1, and the other end of the frame 1 is provided with a unloading area 12, and the material transport cart 2 can slide along the length direction of the frame 1 so that the material transport cart 2 can reciprocate between the material receiving area 11 and the unloading area 12.

[0034] It can be understood that the size of the material receiving portion 21 can be adjusted according to the size of the shearing machine so as to accommodate the material sheet.

[0035] In some embodiments, Figure 2 As shown, the material transport device 100 also includes a connecting frame 3, which is movably connected to the frame body 1, and the material transport vehicle 2 includes a first vehicle body 22 and a second vehicle body 23, which are movably connected to the connecting frame 3 in opposite directions so that the material transport vehicle 2 can switch between an open state and a combined state, and a moving direction of the first vehicle body 22 and the second vehicle body 23 relative to the connecting frame 3 and a moving direction of the connecting frame 3 relative to the frame body 1 are perpendicular to each other; in the open state, the first vehicle body 22 and the second vehicle body 23 move away from each other to form a make way passage between the first vehicle body 22 and the second vehicle body 23; in the combined state, the first vehicle body 22 and the second vehicle body 23 abut to form a material receiving portion 21.

[0036] Through the above settings, the material transport carts 2 are in a merged state during normal operation. When two material transport carts 2 meet, one of the material transport carts 2 can be switched to an open state, and a make way passage can be formed in the middle, and the other material transport cart 2 can pass through the make way passage, thereby realizing the exchange of positions of the two material transport carts 2, so that multiple material transport carts 2 can be alternately moved to the material receiving area 11 for receiving materials.

[0037] As an example, Figure 2 and Figure 3 As shown, the connecting frame 3 includes two slides 31, and the two slides 31 are symmetrically arranged along the width direction of the frame body 1. The frame body 1 has two first slide grooves 13 extending along its length direction, and the two first slide grooves 13 are symmetrically arranged along the width direction of the frame body 1. The two slides 31 can slide with the first slide grooves 13 respectively, and the slides 31 can drive the material transport vehicle 2 to move back and forth between the material receiving area 11 and the material unloading area 12. In addition, two connecting frames 3 are correspondingly provided for one material transport vehicle 2, and the two connecting frames 3 are arranged at intervals along the length direction of the frame body 1, which can provide support for the material transport vehicle 2 and improve the sliding stability of the material transport vehicle 2.

[0038] The first vehicle body 22 and the second vehicle body 23 are respectively slidably connected to the two slides 31, and the sliding direction of the first vehicle body 22 and the second vehicle body 23 relative to the slides 31 is the width direction of the frame body 1; the relative sliding of the first vehicle body 22 and the second vehicle body 23 can enable the material transport vehicle 2 to switch between the merged state and the open state.

[0039] In some embodiments, at least one material transport vehicle 2 is a first material transport vehicle 24, and at least one material transport vehicle 2 is a second material transport vehicle 25. The moving directions of the first material transport vehicle 24 and the second material transport vehicle 25 are opposite, so that the first material transport vehicle 24 and the second material transport vehicle 25 move alternately to the material receiving area 11.

[0040] The moving directions of the first material transport cart 24 and the second material transport cart 25 are opposite, so the first material transport cart 24 or the second material transport cart 25 is located in the material receiving area 11; for example, when the first material transport cart 24 is full of material plates, the first material transport cart 24 moves to the unloading area 12, and the second material transport cart 25 moves to the material receiving area 11 at the same time. When the first material transport cart 24 arrives at the unloading area 12, the second material transport cart 25 arrives at the material receiving area 11, thereby ensuring that the material transport cart 2 can be alternately located in the material receiving area 11 to ensure that the material plates continuously falling from the unloading port can fall onto the material transport cart 2.

[0041] As an example, Figure 1 and Figure 2 As shown, there are two material transport vehicles 2 , namely a first material transport vehicle 24 and a second material transport vehicle 25 .

[0042] In some embodiments, the second material transport cart 25 includes a first guide member 251 and a second guide member 252, the first guide member 251 is connected to the first body 22 of the second material transport cart 25, and the second guide member 252 is connected to the second body 23 of the second material transport cart 25; the first material transport cart 24 includes a first trigger member 241 and a second trigger member 242, the first trigger member 241 is connected to the first body 22 of the first material transport cart 24, and the second trigger member 242 is connected to the second body 23 of the first material transport cart 24, the first trigger member 241 is used to stop the first guide member 251, and the second trigger member 242 is used to stop the second guide member 252, so that the first body 22 and the second body 23 of the second material transport cart 25 are away from each other.

[0043] Through the above arrangement, after the first material transport cart 24 is filled with material plates, the first material transport cart 24 moves from the material receiving area 11 to the unloading area 12. When the first material transport cart 24 meets the second material transport cart 25, the first trigger member 241 of the first material transport cart 24 stops at the first guide member 251, and the second trigger member 242 stops at the second guide member 252. As the first material transport cart 24 and the second material transport cart 25 continue to move, the first trigger member 241 drives the first guide member 251 to move outward along the width direction of the frame 1, and the second trigger member 242 drives the second guide member 252 to move outward along the width direction of the frame 1, thereby driving the second material transport cart 25 to switch from the merged state to the open state, and the first material transport cart 24 enters the unloading area 12 through the make way channel.

[0044] Alternatively, if Figure 2 As shown, the first material transport vehicle 24 also includes a first guide member 251 and a second guide member 252. The first guide member 251 and the first trigger member 241 are respectively arranged on both sides of the first vehicle body 22 along the length direction of the frame body 1, and the second guide member 252 and the second trigger member 242 are respectively arranged on both sides of the second vehicle body 23 along the length direction of the frame body 1.

[0045] The structure of the second material transporting trolley 25 is the same as that of the first material transporting trolley 24 , that is, the second material transporting trolley 25 further includes a first triggering member 241 and a second triggering member 242 .

[0046] Therefore, both the first material transport cart 24 and the second material transport cart 25 can switch between the combined state and the open state; when the second material transport cart 25 is fully loaded, the second material transport cart 25 moves from the material receiving area 11 to the unloading area 12, and the first trigger member 241 and the second trigger member 242 of the second material transport cart 25 respectively stop at the first guide member 251 and the second guide member 252 of the first material transport cart 24, so that the first material transport cart 24 can be switched from the combined state to the open state, and the second material transport cart 25 reaches the unloading area 12 through the yield channel.

[0047] In some embodiments, Figure 2 and Figure 3 As shown, the first guide member 251 has a first guide surface 2511, and the second guide member 252 has a second guide surface 2521. The first guide surface 2511 gradually moves away from the second guide member 252 in a direction away from the first vehicle body 22, and the second guide surface 2521 gradually moves away from the first guide member 251 in a direction away from the second vehicle body 23; the first trigger member 241 has a first trigger surface 2411, and the second trigger member 242 has a second trigger surface 2421. The first trigger surface 2411 gradually approaches the second trigger member 242 in a direction away from the first vehicle body 22, and the second trigger surface 2421 gradually approaches the first trigger member 241 in a direction away from the second vehicle body 23.

[0048] Through the above arrangement, when the first trigger member 241 and the second trigger member 242 move toward the first guide member 251 and the second guide member 252, the first trigger member 241 and the second trigger member 242 can be inserted between the first guide member 251 and the second guide member 252, so that the first trigger surface 2411 can stop against the first guide surface 2511, and the second trigger surface 2421 can stop against the second guide surface 2521.

[0049] As an example, Figure 2 As shown, the projections of the first trigger member 241 and the second trigger member 242 on the horizontal plane are both in the shape of a right triangle, and match the shapes of the first vehicle body 22 and the second vehicle body 23 respectively. The surfaces of the first trigger member 241 and the second trigger member 242 that are away from each other are the first trigger surface 2411 and the second trigger surface 2421 respectively. The angle between the first trigger surface 2411 and the second trigger surface 2421 is 20° to 60°, for example, 30°, 45°, etc.

[0050] The projections of the first guide member 251 and the second guide member 252 on the horizontal plane are fan-shaped and match the shapes of the first vehicle body 22 and the second vehicle body 23 respectively. The first guide surface 2511 and the second guide surface 2521 are both arc surfaces. When the first vehicle body 22 and the second vehicle body 23 are combined, the first guide surface 2511 and the second guide surface 2521 are in contact with each other.

[0051] In some embodiments, Figure 4 As shown, a first elastic member 41 is provided between the first guide member 251 and the connecting frame 3, and the first elastic member 41 is used to apply an elastic force to the first guide member 251 toward the second guide member 252; a second elastic member 42 is provided between the second guide member 252 and the connecting frame 3, and the second elastic member 42 is used to apply an elastic force to the second guide member 252 toward the first guide member 251.

[0052] When two material transport carts 2 meet, one of the material transport carts 2 forces the other material transport cart 2 to switch to an open state to form a make way passage. After the material transport cart 2 passes through the make way passage, the first body 22 and the second body 23 of the material transport cart 2 in the open state approach each other under the action of the first elastic member 41 and the second elastic member 42, so that the material transport cart 2 automatically switches to a merged state to receive the material.

[0053] As an example, Figure 4As shown, the carriage 31 has a second slide groove 311, and the material transport vehicle 2 further includes four sliders 26, which correspond to the carriage 31 one by one and slide in cooperation with the slide groove; two sliders 26 are respectively connected to the first trigger member 241 and the second trigger member 242, and the other two sliders 26 are respectively connected to the first guide member 251 and the second guide member 252, so that the first vehicle body 22 and the second vehicle body 23 can slide stably. The first elastic member 41 and the second elastic member 42 are respectively installed in the second slide groove 311.

[0054] Optionally, the first elastic member 41 and the second elastic member 42 are both springs, which are arranged on the side of the slider 26 away from the material transport vehicle 2, one end of the spring abuts against the slider 26, and the other end abuts against the groove wall of the second slide groove 311, and the spring is in a compressed state.

[0055] Thus, the first elastic member 41 can apply an elastic force to the first vehicle body 22 toward the second vehicle body 23 , and the second elastic member 42 can apply an elastic force to the second vehicle body 23 toward the first vehicle body 22 , so that the first vehicle body 22 and the second vehicle body 23 are automatically switched to a merged state.

[0056] In some embodiments, Figure 1 and Figure 3 As shown, the material transport device 100 further includes a first drive assembly 51 and a second drive assembly 52 . The first drive assembly 51 is used to drive the first material transport vehicle 24 to move, and the second drive assembly 52 is used to drive the second material transport vehicle 25 to move.

[0057] By providing the first driving assembly 51 and the second driving assembly 52, the first material transporting vehicle 24 and the second material transporting vehicle 25 can be automatically moved, thereby improving the convenience of operation.

[0058] In some embodiments, Figure 1 and Figure 3 As shown, the first drive assembly 51 includes a first screw 511 and a first nut 512, the first screw 511 is rotatably connected to the frame 1, the first nut 512 is connected to the first material transport cart 24 and is threadedly engaged with the first screw 511; the second drive assembly 52 includes a second screw 521 and a second nut 522, the second screw 521 is rotatably connected to the frame 1, the second nut 522 is connected to the second material transport cart 25 and is threadedly engaged with the second screw 521.

[0059] Through the above arrangement, the first material transporting trolley 24 can be driven to move by rotating the first lead screw 511, and the second material transporting trolley 25 can be driven to move by rotating the second lead screw 521, and the operation is more convenient.

[0060] Alternatively, if Figure 1 and Figure 3As shown, the number of the first drive assembly 51 and the second drive assembly 52 are both two, the two first drive assemblies 51 are respectively used to drive the first body 22 and the second body 23 of the first material transport vehicle 24 to move, and the two second drive assemblies 52 are respectively used to drive the first body 22 and the second body 23 of the second material transport vehicle 25 to move.

[0061] As an example, Figure 3 As shown, the first driving assembly 51 includes a first screw 511 and two first nuts 512. The two first nuts 512 cooperate with the first screw 511, and the two first nuts 512 are respectively fixedly connected to the two slides 31 arranged on the same side; the two first driving assemblies 51 are respectively arranged on both sides of the material transport vehicle 2, and the simultaneous rotation of the two first screws 511 can drive the first body 22 and the second body 23 of the first material transport vehicle 24 to move synchronously.

[0062] like Figure 1 As shown, the structure of the second driving assembly 52 is the same as that of the first driving assembly 51 , and the simultaneous rotation of the two second lead screws 521 can drive the first body 22 and the second body 23 of the second material transport vehicle 25 to move synchronously.

[0063] like Figure 2 and Figure 3 As shown, the height of the two first drive assemblies 51 is lower than the first material transport cart 24, and the height of the two second drive assemblies 52 is higher than the second material transport cart 25; thus, when the first material transport cart 24 and the second material transport cart 25 meet, the first nut 512 and the second nut 522 can be prevented from colliding with each other.

[0064] In some embodiments, Figure 5 As shown, a transmission assembly 6 is provided between the first lead screw 511 and the second lead screw 521, and the transmission assembly 6 includes a transmission shaft 61, a first bevel gear pair 62 and a second bevel gear pair 63. The transmission shaft 61 is rotatably connected to the frame 1, one end of the transmission shaft 61 is connected to the first lead screw 511 through the first bevel gear pair 62, and the other end of the transmission shaft 61 is connected to the second lead screw 521 through the second bevel gear pair 63, so that the rotation directions of the first lead screw 511 and the second lead screw 521 are opposite.

[0065] Through the above arrangement, the rotation directions of the first screw 511 and the second screw 521 can be kept opposite, so that the first material transport cart 24 and the second material transport cart 25 can be moved alternately to the material receiving area 11, so as to transport the sheared material plates out of the shearing machine, thereby improving the operating efficiency of the shearing machine.

[0066] As an example, Figure 5As shown, there are two transmission assemblies 6 , which are arranged on both sides along the width direction of the frame 1 , respectively, and the first lead screw 511 and the second lead screw 521 arranged on the same side of the frame 1 are connected through the transmission assembly 6 .

[0067] Alternatively, if Figure 3 As shown, the two first lead screws 511 are transmission connected via a synchronous belt structure 54 .

[0068] Thereby, the first vehicle body 22 and the second vehicle body 23 of the first material transport vehicle 24 can always keep moving synchronously.

[0069] Alternatively, if Figure 2 As shown, one of the first lead screws 511 is connected to a drive motor 53 .

[0070] Thus, the driving motor 53 can drive one of the first lead screws 511 to rotate, and then drive the other first lead screw 511 to rotate through the synchronous belt structure 54, drive one of the second lead screws 521 to rotate through the transmission assembly 6, and the other first lead screw 511 drives the other second lead screw 521 to rotate through the transmission assembly 6. In other words, the driving motor 53 can drive the two first lead screws 511 and the two second lead screws 521 to rotate synchronously.

[0071] Optionally, pressure sensors are provided on the lower sides of the first material transporting trolley 24 and the second material transporting trolley 25 , and the pressure sensors are electrically connected to the driving motor 53 .

[0072] Therefore, when the first material transport cart 24 or the second material transport cart 25 receives the material, when the weight of the material plate reaches the set value, the pressure sensor can send a signal to the drive motor 53 to start the drive motor 53, thereby controlling the fully loaded first material transport cart 24 or the fully loaded second material transport cart 25 to move to the unloading area.

[0073] In some embodiments, Figure 3 As shown, the lower side of the material transport vehicle 2 is provided with support wheels 7 .

[0074] When the material transport vehicle 2 is fully loaded, the support wheels 7 can provide greater support force for the movement of the material transport vehicle 2, thereby improving the material transport stability of the material transport vehicle 2.
