Description

Technical Field

[0001] The utility model relates to a loading and unloading vehicle system, in particular to an automatic loading and unloading vehicle system, belonging to the technical field of logistics and transportation. Background Art

[0002] The automated loading and unloading system realizes automatic loading and unloading of goods through mechanization and intelligent means, which improves logistics efficiency, reduces labor costs and labor intensity, and reduces operational errors and the risk of cargo damage. When loading and unloading roll materials, it is troublesome to unload them because roll materials are usually large in size.

[0003] An automated loading and unloading system and method for roll materials disclosed in Chinese patent publication CN112573241B includes a vertical lifting mechanism installed on a transverse moving mechanism, and an L-shaped hook for loading and unloading roll materials is installed at the lower end of the vertical lifting mechanism. The L-shaped hook is composed of a vertical rod and a horizontal rod, and is close to the lower part of the vertical rod.

[0004] The above device inserts the L-shaped hook into the axial socket of the roll material through the action of the lateral moving mechanism. In actual use, it is found that lifting only one side of the roll material will cause uneven force on the roll material, which may cause deformation or damage to the material. Lifting on one side is likely to cause the roll material to tilt or shake, reducing the stability and safety of the unloading process. For this reason, we provide an automated loading and unloading vehicle system. Utility Model Content

[0005] The utility model provides an automatic loading and unloading vehicle system, which can lift and lower both sides of a roll material at the same time, so that the roll material is evenly stressed, and the roll material is prevented from tilting or shaking.

[0006] The utility model is realized through the following technical scheme: comprising a gantry, the gantry comprising a crossbeam, a support column and a mounting plate, the gantry being provided with two horizontal moving mechanisms, the horizontal moving mechanisms being provided with a loading and unloading mechanism for loading and unloading rolled materials, and a controller being fixed on the crossbeam.

[0007] The horizontal moving mechanism includes a moving shell, a first servo motor is fixed to the side of the moving shell, a driving wheel is fixed to one end of the output shaft of the first servo motor extending to the inside of the moving shell, and a sliding groove is provided on the top surface of the crossbeam for sliding contact with the driving wheel.

[0008] The loading and unloading mechanism includes a second servo motor fixed on the side of the moving shell, a bidirectional lead screw is fixed on the output end of the second servo motor, two symmetrical sliders are threadedly connected to the surface of the bidirectional lead screw, guide rods are fixed on the sides of the sliders, guide cylinders are arranged on the sides of the guide rods, slide rails are fixed on the sides of the two moving shells close to each other, a moving block is slidably connected to the slide rails, the side of the moving block is fixed to the guide cylinder, a U-shaped frame is fixed on the side of the moving block, a flashlight push rod is fixed to the bottom of the U-shaped frame, and a cross bar is fixed to the output end of the flashlight push rod.

[0009] Specifically, the bottom surface of the cross beam is fixed to the upper end of the support column, and the top surface of the mounting plate is fixed to the lower end of the support column.

[0010] Furthermore, the inner wall of the movable shell is rotatably connected to a driven wheel via a bearing, and the driven wheel is in sliding contact with the slide groove. The contact area between the movable shell and the slide groove is increased by providing the driven wheel, thereby effectively improving the stability of the horizontal movable mechanism.

[0011] Furthermore, the end of the bidirectional lead screw away from the second servo motor is connected to the side of the movable shell through a bearing, thereby preventing the end of the bidirectional lead screw away from the second servo motor from sliding.

[0012] Specifically, a rubber pad is sleeved on the side of the cross bar, and the outer contour of the rubber pad is cylindrical. The rubber pad can protect the roll material and prevent the roll material from being damaged.

[0013] Furthermore, a 3D camera is installed at one end of the cross bar, the controller is electrically connected to the 3D camera, the controller is electrically connected to the second servo motor, and the controller is electrically connected to the first servo motor. The 3D camera can improve the accuracy of positioning the roll material.

[0014] Specifically, the guide rod and the guide cylinder are clearance-matched to prevent the guide rod from exerting downward pressure on the guide cylinder.

[0015] The utility model provides an automatic loading and unloading system, which has the following beneficial effects:

[0016] 1. The automated loading and unloading vehicle system can drive the driven wheel to rotate by starting the first servo motor, so that the moving shell drives the second servo motor to move to the position of the roll material, and then the started second servo motor can drive the bidirectional lead screw to rotate, so that the limited slider drives the guide rod, guide cylinder, slide rail, moving block, U-shaped frame, flashlight push rod and cross bar to move, and two cross bars close to each other are inserted into the axis of both sides of the roll material, so that both sides of the roll material can be lifted and lowered at the same time, so that the roll material is evenly stressed, avoiding tilting or shaking of the roll material during loading and unloading.

[0027] See also Figure 1 to Figure 5 The embodiment of the utility model provides an automated loading and unloading system, including a gantry 1, the gantry 1 includes a crossbeam 101, a support column 102 and a mounting plate 103, the bottom surface of the crossbeam 101 is fixed to the upper end of the support column 102, the top surface of the mounting plate 103 is fixed to the lower end of the support column 102, and a controller 4 is fixed on the crossbeam 101, and the model of the controller 4 is Siemens S7-300.

[0028] Please refer to Figure 1 , Figure 4 and Figure 5Two horizontal moving mechanisms 2 are arranged on the door frame 1, and the horizontal moving mechanism 2 includes a moving shell 201, a first servo motor 202 is fixed on the side of the moving shell 201, a controller 4 is electrically connected to the first servo motor 202, and the first servo motor 202 can be controlled by the controller 4, an output shaft of the first servo motor 202 extends to one end of the inside of the moving shell 201 and a driving wheel 203 is fixed, and an inner wall of the moving shell 201 is rotatably connected to a driven wheel 204 through a bearing, and the driven wheel 204 and the slide groove 205 are in sliding contact. By setting the driven wheel 204, the contact area between the moving shell 201 and the slide groove 205 is increased, and the stability of the horizontal moving mechanism 2 is further improved. The top surface of the beam 101 is provided with a slide groove 205 that is in sliding contact with the driving wheel 203. The rotation of the first servo motor 202 will drive the driving wheel 203 to rotate. At the same time, the two first servo motors 202 are started, and the two driving wheels 203 will respectively drive the moving shell 201 to move on the top surface of the beam 101, thereby driving the cross bar 310 to the position of the roll material.

[0029] Please refer to Figure 1 , Figure 2 and Figure 3 The horizontal moving mechanism 2 is provided with a loading and unloading mechanism 3 for loading and unloading the roll material. The loading and unloading mechanism 3 includes a second servo motor 301 fixed on the side of the moving shell 201. The second servo motor 301 and the first servo motor 202 are of Panasonic MSMA10ZP1U with a rated power of 1000W. The controller 4 is electrically connected to the second servo motor 301, and the second servo motor 301 can be controlled by the controller 4. A bidirectional lead screw 302 is fixed to the output end of the second servo motor 301. The rotation of the second servo motor 301 will drive the bidirectional lead screw 302 to rotate. The end of the bidirectional lead screw 302 away from the second servo motor 301 is connected to the side of the moving shell 201 through a bearing to prevent the end of the bidirectional lead screw 302 away from the second servo motor 301 from sliding. The surface of the bidirectional lead screw 302 is threadedly connected with two symmetrical sliders 303. The sliders 303 are limited, so when the bidirectional lead screw 302 rotates, the two sliders 303 will move toward each other.

[0030] Furthermore, a guide rod 304 is fixed to the side of the slider 303, and a guide cylinder 305 is arranged on the side of the guide rod 304. The guide rod 304 and the guide cylinder 305 are clearance-matched. Therefore, the pressure from the roll material on the moving block 307 will not be transmitted to the slider 303 through the guide cylinder 305 and the guide rod 304, so as to avoid the two-way lead screw 302 being continuously subjected to pressure, which causes the two-way lead screw 302 to deform. The sides of the two moving shells 201 that are close to each other are fixed with slide rails 306, and the slide rails 306 are slidably connected with the moving block 307. The moving slider 303 will drive the guide rod 304 to move, which can drive the guide cylinder 305 to move through the guide rod 304, and which can drive the moving block 307 to slide on the slide rails 306 through the guide cylinder 305.

[0031] The side of the moving block 307 is fixed to the guide cylinder 305, and a U-shaped frame 308 is fixed to the side of the moving block 307. A flashlight push rod 309 is fixed to the bottom of the U-shaped frame 308. The model of the flashlight push rod 309 is DT1600. The flashlight push rod 309 is fixed in the middle of the bottom of the U-shaped frame 308. A cross bar 310 is fixed to the output end of the flashlight push rod 309. The two cross bars 310 are close to each other. A rubber pad 311 is sleeved on the side of the cross bar 310. The outer contour of the rubber pad 311 is cylindrical. A 3D camera 312 is installed at one end of the cross bar 310. The 3D camera 312 can detect the axis of the roll material, and then transmit the detected signal to the controller 4. The controller 4 controls the flashlight push rod 309 and the second servo motor 301, and finally the two cross bars 310 are inserted into the axis of the roll material. The controller 4 is electrically connected to the 3D camera 312.

[0032] Working principle: When unloading, first move the vehicle under the cross beam 101, then start the first servo motor 202 to drive the driven wheel 204 to rotate, so that the moving shell 201 drives the second servo motor 301 to move, and the cross bar 310 is moved to the top of the roll material, and then the started second servo motor 301 drives the bidirectional lead screw 302 to rotate, so that the limited slider 303 drives the guide rod 304, guide cylinder 305, slide rail 306, moving block 307, U-shaped frame 308, flashlight push rod 309 and cross bar 310 to approach each other, and the two cross bars 310 close to each other are inserted into the axis of both sides of the roll material. The same is true when loading, and then both sides of the roll material can be lifted and lowered at the same time, so that the roll material is evenly stressed, avoiding the roll material from tilting or shaking during loading and unloading.
