Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, in particular to a belt transmission terminal transfer device. Background Art

[0002] In the automatic loading and unloading device, a transfer device is set at the conveying end to pick up and place materials at the preset position. When picking up materials at low height positions, especially at the bottom layer, it is necessary to lift the materials through a lifting device.

[0003] Using a suction cup to suck up materials to perform lifting operations is a common method. When the suction surface is the side of the material, the posture of the suction surface of the suction cup is usually designed to be in a vertical state.

[0004] The inventor believes that when using this method to transfer heavy-load materials, high requirements are placed on the suction force of the suction cup and the structural strength of the lifting component, especially when the outer packaging of the material is a carton, which can easily cause deformation of the carton. Utility Model Content

[0005] In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a belt transmission end transfer device, which does not need to lift the material as a whole when taking the material, and is not likely to cause deformation of the outer packaging.

[0006] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0007] A belt transmission end transfer device, used to realize material transfer between a conveyor belt and a target position, comprising:

[0008] A material picking actuator, wherein the material picking actuator is a suction cup, and a suction surface of the material picking actuator is arranged at the front side of the outer end thereof;

[0009] The moving part, the material taking actuator is connected to the moving part, and the moving part includes:

[0010] A lifting assembly, the lifting assembly includes a mounting plate, the material picking actuator is rotatably mounted on the mounting plate, and the lifting assembly is used to drive the material picking actuator to move in a direction perpendicular to the conveying direction of the conveyor belt, so that the material picking actuator can switch between the lower end of the conveying surface of the conveyor belt and the upper end of the conveying surface extending from the conveyor belt;

[0011] A second limiting structure is provided on the mounting plate, and the second limiting structure is used to prevent the material picking actuator from rotating too far downward. When the material picking actuator rotates to fit with the second limiting structure, the angle between the suction surface of the material picking actuator and the horizontal plane forms a preset acute angle.

[0012] Further, in the belt transmission end transfer device described in the present application, the moving part includes a translation assembly, the moving part of the translation assembly includes a mounting frame, the lifting assembly is arranged on the mounting frame, and the translation assembly is used to move the lifting assembly in a direction parallel to the conveying direction of the conveyor belt;

[0013] Based on the above structure, during the material picking operation, the transfer device is used to transfer the material at the target position to the conveyor belt; during the material unloading operation, it is used to transfer the material on the conveyor belt to the target position. During the material picking operation, the moving part drives the material picking actuator to move out of the outer end of the conveyor belt, the material picking actuator obtains the material, and the moving part moves the material picking actuator until the material is above the conveyor belt. During the material picking process, when the material picking actuator lifts the material, it does not lift the material as a whole, but lifts one side of the material so that the material is lifted up as a whole. During the lifting process, the material picking actuator rotates downward to fit with the second limiting structure. At this time, the bottom of the material near the suction surface is just lifted to a level higher than the outer end of the conveyor belt. During this process, the suction surface of the material picking actuator rotates downward to always fit the side of the material. Therefore, the belt transmission end transfer device described in the present application can transfer the material to the conveyor belt without lifting the material as a whole when taking the material. The suction force of the suction cup and the load requirement of the lifting component are relatively low, and because the suction surface rotates as the material is lifted, it is not easy to cause deformation of the outer packaging.

[0014] Furthermore, in the belt transmission end transfer device described in the present application, the lifting assembly includes a first drive device, the first drive device is installed on a mounting frame, the telescopic part of the first drive device is connected to a transmission assembly, the mounting plate is connected to the transmission assembly, and the mounting plate and the first drive device are arranged on both sides of the transmission assembly corresponding to the conveying direction of the conveyor belt.

[0015] In traditional lifting devices, the driving components and transmission components are often arranged on one side of the lifting direction. Based on the requirements of this application, a cylinder is generally used to push the material picking actuator from below to achieve the lifting operation. However, when transferring materials to an external low-height position, especially a bottom position, it is necessary to swing the end frame downward so that the material picking actuator corresponds to the lower side position of the material. If a cylinder is arranged below the material picking actuator, the material picking actuator will not be able to descend to the preset position when extended.

[0016] Based on the above structure, the principle of the belt transmission end transfer device is that the transmission assembly and the first drive device are arranged on the inner side of the mounting plate, which can ensure that when transferring materials to the external bottom surface, the material taking actuator can correspond to the position of the lowest point of the bottom surface after being extended. It has the advantages of compact structure in the vertical direction.

[0017] Furthermore, in the present application, a belt transmission end transfer device is described, wherein the transmission assembly includes a pair of connecting rods, and the two ends of the pair of connecting rods are rotatably connected to the mounting plate and the mounting frame respectively, and the first driving device is a driving cylinder, and the first driving device is rotatably connected to the mounting frame, and the telescopic component of the first driving device is rotatably connected to one of the connecting rods. As a preferred embodiment of the present application, based on the above structure, when performing material picking operations, the lifting assembly can drive the material picking actuator to move synchronously toward the conveyor belt during the rising process, and complete the lifting and movement toward the conveyor belt in one working cycle. When the material moves onto the conveyor belt, the material picking actuator puts down the material, and the translation assembly drives the lifting assembly to move until the material picking actuator is separated from the material, and the lifting assembly then drives the material picking actuator to be stored under the conveying plane.

[0018] Furthermore, in the belt transmission end transfer device described in the present application, the connecting rods are arranged in pairs along the width direction of the conveyor belt, that is, a pair of connecting rods are arranged on each side of the width direction. A connecting piece is installed between the pair of connecting rods in the width direction, and the telescopic component of the first driving device is rotatably connected to the connecting piece.

[0019] Furthermore, in the belt transmission end transfer device described in the present application, the material taking actuator is rotatably connected to the mounting plate, the rotating axis of the material taking actuator is parallel to the width direction of the conveyor belt, and the mounting plate is provided with a first limiting surface;

[0020] After the second drive assembly drives the end frame to swing downward to a preset angle, when transferring materials, the material picking actuator can passively rotate upward to fit with the first limit surface when it is in contact with the side of the material. As a preferred embodiment of the present application, the first limit surface is used to limit the angle at which the material picking actuator flips upward from a horizontal position; the first limit surface is used to ensure the stability of the upward swing angle when the suction surface of the material picking actuator fits with the contact surface of the external material.

[0021] It can be seen from the above technical solution that the utility model has the following beneficial effects:

[0022] The utility model provides a transfer device at the end of a belt transmission. When taking materials, the materials do not need to be lifted as a whole to transfer the materials to the conveyor belt. The suction force of the suction cup and the load requirements of the lifting component are relatively low. Moreover, since the suction surface rotates as the materials are lifted, it is not easy to cause deformation of the outer packaging. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Combination Figure 1 and Figure 2 A belt transmission end transfer device 33 is shown, which is used to realize material transfer between a conveyor belt and a target location, and includes:

[0035] A material picking actuator 330, wherein the material picking actuator 330 is a suction cup, and a suction surface of the material picking actuator 330 is arranged at the front side of the outer end thereof;

[0036] The moving part, the material taking actuator 330 is connected to the moving part, and the moving part includes:

[0037] A lifting assembly 331, wherein the lifting assembly 331 comprises a mounting plate 3311, and the material picking actuator 330 is rotatably mounted on the mounting plate 3311. The lifting assembly 331 is used to drive the material picking actuator 330 to move in a direction perpendicular to the conveying direction of the conveyor belt, so that the material picking actuator 330 can switch between the lower end of the conveying surface of the conveyor belt and the upper end of the conveying surface extending from the conveyor belt;

[0038] A translation assembly 332, wherein the moving part of the translation assembly 332 includes a mounting frame 3321, the lifting assembly 331 is arranged on the mounting frame 3321, and the translation assembly 332 is used to move the lifting assembly 331 in a direction parallel to the conveying direction of the conveyor belt;

[0039] The mounting plate 3311 is provided with a second limiting structure 33112, which is used to prevent the material picking actuator 330 from rotating too far downward. When the material picking actuator 330 rotates to fit with the second limiting structure 33112, the angle between the suction surface of the material picking actuator 330 and the horizontal plane forms a preset acute angle.

[0040] Based on the above structure, during the material picking operation, the transfer device 33 is used to transfer the material at the target position to the conveyor belt; during the material unloading operation, it is used to transfer the material on the conveyor belt to the target position. During the material picking operation, the moving part drives the material picking actuator 330 to move out of the outer end of the conveyor belt, the material picking actuator 330 obtains the material, and the moving part moves the material picking actuator 330 until the material is above the conveyor belt. During the material picking process, when the material picking actuator 330 lifts the material, it does not lift the material as a whole, but lifts one side of the material so that the material is lifted as a whole. During the lifting process, the material picking actuator 330 rotates downward to fit with the second limiting structure 33112. At this time, the bottom of the material near the suction surface is just lifted to a level higher than the outer end of the conveyor belt. During this process, the suction surface of the material picking actuator 330 rotates downward to always fit the side of the material. Based on the above structure, when picking up materials, it is not necessary to lift the materials as a whole to transfer the materials to the conveyor belt. The suction force of the suction cup and the load requirements of the lifting component are relatively low. In addition, since the suction surface rotates as the materials are lifted, it is not easy to cause deformation of the outer packaging. Specifically, the second limiting structure 33112 is a plane. The translation component 332 is driven by a screw motor to move the components. The rotating axis of the material picking actuator is parallel to the width direction of the conveyor belt.

[0041] The lifting assembly 331 includes a first driving device 3312, which is installed on a mounting frame 3321. A transmission assembly is connected to the telescopic part of the first driving device 3312. The mounting plate 3311 is connected to the transmission assembly. The mounting plate 3311 and the first driving device 3312 are arranged on both sides of the transmission assembly corresponding to the conveying direction of the conveyor belt.

[0042] In a conventional lifting device, the driving components and transmission components are often arranged on one side of the lifting direction. Based on the requirements of this application, a cylinder is generally used to push the material picking actuator 330 from below to achieve the lifting operation. However, when transferring materials to an external low-height position, especially a bottom position, it is necessary to swing the end frame 34 downward so that the material picking actuator 330 corresponds to the lower side position of the material. If a cylinder is arranged below the material picking actuator 330, the material picking actuator 330 will be unable to descend to the preset position when extended.

[0043] Based on the above structure, the principle of the belt transmission end transfer device is: the transmission assembly and the first drive device 3312 are arranged on the inner side of the mounting plate 3311, which can ensure that when transferring materials to the external bottom surface, the material taking actuator 330 can correspond to the position of the lowest point of the bottom surface after being extended. It has the advantages of compact structure in the vertical direction.

[0044] The transmission assembly includes a pair of connecting rods 3313, and the two ends of the pair of connecting rods 3313 are rotatably connected to the mounting plate 3311 and the mounting frame 3321 respectively. The first driving device 3312 is a driving cylinder, and the first driving device 3312 is rotatably connected to the mounting frame 3321. The telescopic part of the first driving device 3312 is rotatably connected to one of the connecting rods 3313.

[0045] Based on the above structure, when performing the material picking operation, the lifting assembly 331 can drive the material picking actuator 330 to move synchronously toward the conveyor belt during the rising process, and complete the lifting and moving toward the conveyor belt in one working cycle. When the material moves onto the conveyor belt, the material picking actuator 330 puts down the material, and the translation assembly 332 drives the lifting assembly 331 to move until the material picking actuator 330 is separated from the material, and the lifting assembly 331 then drives the material picking actuator 330 to be stored under the conveying plane.

[0046] The connecting rods 3313 are arranged in pairs along the width direction of the conveyor belt, that is, a pair of connecting rods 3313 is arranged on each side of the width direction. A connecting piece 33131 is installed between the pair of connecting rods 3313 in the width direction, and the telescopic component of the first driving device 3312 is rotatably connected to the connecting piece 33131.

[0047] In this embodiment, the material taking actuator 330 and the lifting assembly 331 are arranged in pairs along the width direction of the conveyor belt.

[0048] Combination Figure 2 and Figure 6 As shown, a first limiting surface 33111 is provided on the mounting plate 3311; when the moving part as a whole is tilted downward and rotated at a preset angle to transfer materials, when the material picking actuator 330 is in contact with the side of the material, it can be passively rotated upward to be in contact with the first limiting surface 33111.

[0049] The first limiting surface 33111 is used to limit the angle of the material picking actuator 330 flipping upward from the horizontal position; the first limiting surface 33111 is used to ensure the stability of the upward swing angle when the suction surface of the material picking actuator 330 is in contact with the contact surface of the external material.

[0050] Example 2

[0051] Combination Figure 3 and 4 As shown, this embodiment provides a terminal conveying device, comprising:

[0052] A conveying assembly 31, wherein a conveying belt 312 is provided on the conveying assembly 31 for conveying materials;

[0053] A belt transmission end transfer device 33 as described in Example 1;

[0054] The terminal frame 34 and the second driving assembly 35, the second driving assembly 35 is used to drive the terminal frame 34 to swing up and down, and the conveying assembly 31 is arranged on the terminal frame 34; the second driving assembly 35 is used to drive the terminal frame 34 to swing to adjust the angle of the conveying surface of the conveying assembly 31. The fixed assembly of the translation assembly 332 is arranged on the terminal frame 34.

[0055] Based on the above structure, when picking up materials, the moving part drives the picking up material actuator 330 to move out of the outer end of the conveyor belt 312, the picking up material actuator 330 obtains the materials, and the moving part moves the picking up material actuator 330 until the materials are above the conveyor belt 312;

[0056] When unloading, the lifting assembly 331 drives the material picking actuator 330 to rise to the upper end of the conveying surface, and the translation assembly 332 is used to push the material on the conveyor belt 312 to move out of the material picking actuator 330. And the material picking actuator 330 can be moved to the lower end of the conveying surface of the conveying assembly 31 through the lifting assembly to achieve storage. The conveyor belt 312 is arranged in intervals along the width direction, and the material picking actuator 330 is arranged in the interval cavity of the conveyor belt 312.

[0057] The terminal conveying device is integrally arranged on a cantilever that swings up and down (such as Figure 1 As shown in FIG. 1 ), the second drive assembly 35 is required to adjust the posture of the end frame 34 to ensure the stability of material transportation according to different heights. After the second drive assembly 35 drives the end frame 34 to swing downward by a preset angle, when the material is transferred, the material taking actuator 330 is in contact with the side of the material and can be passively rotated upward to be in contact with the first limit surface 33111.

[0058] Combination Figure 4 and 5 As shown, in this embodiment, the end frame 34 is provided with an avoidance notch 341 at the bottom of the outer end corresponding to the conveyor belt 312; when the material is transferred to the external low height position, especially the bottom surface position, the second drive assembly 35 can drive the end frame 34 to swing down to a preset angle, so that the outer end of the conveyor belt 312 drops to a position corresponding to the lower side of the material side, such as Figure 5 As shown, the avoidance notch 341 is used to prevent the outer bottom of the end frame 34 from interfering with the external transfer position when the end frame 34 swings down to the lowest point.

[0059] During the material transfer process at the general position, the conveying surface of the conveying component 31 is horizontal. During the material picking process, the material picking actuator 330 sucks the lower side of the material and transfers the material to the conveyor belt 312 through the moving part. During the material discharge process, the material picking actuator 330 pushes the material to the preset external position. However, when transferring the material at the bottom position, since the conveying surface of the conveying component 31 is at a certain height from the bottom of the terminal frame 34, if the conveying surface of the conveying component 31 is still conveying the material in a horizontal posture, when picking up the material, the material needs to be lifted above the height of the conveying surface of the conveying component 31 from the bottom of the terminal conveying device, resulting in the lifting stroke of the lifting component 331 being too high, affecting the lifting stability; and during the material discharge operation, when the material leaves the conveyor belt 312, there is a risk of dumping due to the large height difference.

[0060] The avoidance notch 341 forms an avoidance slope 3410 that is inclined with respect to the conveying direction of the conveying assembly 31 (in this embodiment, the inclination angle is 15°); when the second driving assembly 35 drives the end frame 34 to swing downward to the lowest point, the avoidance slope 3410 is horizontal.

[0061] Specifically, the material is a cube. When transferring the material, the material taking actuator 330 is used to suck the lower side of the side of the cube. When the transfer position of the material is the bottom surface of the lowest layer, that is, the cube is transported from the bottom surface to the conveyor belt 312, or when the cube is transported from the conveyor belt 312 to the external bottom surface, in order to ensure that the position of the outermost end of the conveying component 31 corresponds to the lower side of the side of the material, the second driving component 35 needs to drive the end frame 34 to swing downward at a preset inclination angle to reduce the height of the outer end of the conveying component 31 to the lowest point. Specifically, at this time, the avoidance slope 3410 is parallel to the external bottom surface. When performing material picking operations, the moving part drives the material picking actuator 330 to extend out of the outer end of the conveying component 31. At this time, after the material picking actuator 330 contacts the cube, the material picking actuator 330 will passively rotate upward until it is in contact with the first limiting surface 33111. At this time, the suction surface of the material picking actuator 330 is perpendicular to the external bottom surface to ensure that the suction surface of the material picking actuator 330 is in contact with the side of the cube to ensure the stability of material transfer at low heights, especially at the bottom layer.

[0062] Furthermore, in this embodiment, the second driving assembly 35 includes a terminal longitudinal swing assembly, and the terminal longitudinal swing assembly is used to drive the terminal frame 34 to swing longitudinally, and the terminal longitudinal swing assembly includes:

[0063] A longitudinal swing drive cylinder 351, wherein the longitudinal swing drive cylinder 351 is rotatably mounted on the intermediate frame 41; specifically, the longitudinal swing drive cylinder 351 is an electric push cylinder, and the cylinder body of the longitudinal swing drive cylinder 351 is rotatably mounted on the bottom of the intermediate frame 41;

[0064] The transmission frame 352 is rotatably mounted on the intermediate frame 41, and the telescopic assembly of the longitudinal swing drive cylinder 351 is rotatably connected to the transmission frame 352; the end drive seat 353 is rotatably mounted on the end of the intermediate frame 41 near the end conveying assembly 3, and the end frame 34 is mounted on the end drive seat 353; the transmission rod 354, the swing transmission rod 354 is rotatably connected to the transmission frame 352 and the end drive seat 353 respectively. Specifically, the two ends of the swing transmission rod 354 are rotatably connected to the transmission frame 352 and the end drive seat 353 respectively. The end longitudinal swing assembly is used to drive the end frame 34 to swing longitudinally so that the end frame 34 can adjust its posture following the longitudinal swing of the intermediate frame 41. The transmission process of the end longitudinal swing assembly is: the longitudinal swing drive cylinder 351 drives its telescopic assembly to move, and then drives the transmission frame 352, the swing transmission rod 354, and the end drive seat 353 to rotate in sequence, thereby driving the end frame 34 to swing longitudinally.

[0065] In this embodiment, the transmission frame 352 includes a shaft 3521, which is rotatably mounted on the intermediate frame 41. A first connecting rod 3522 is fixed on the shaft 3521, and the first connecting rod 3522 is arranged at the center of the shaft 3521. The first connecting rod 3522 is rotatably connected to the telescopic component of the longitudinal swing drive cylinder 351; the swing transmission rods 354 are arranged in pairs, and a second connecting rod 3523 is fixed at each end of the transmission frame 352, and the second connecting rod 3523 is rotatably connected to the swing transmission rod 354; the end drive seat 353 includes a third connecting rod 3531 fixedly arranged at both ends of the end drive seat 353, and the third connecting rod 3531 is rotatably connected to the swing transmission rod 354. Based on the above structure, the force of the longitudinal swing drive cylinder 351 acting on the end drive seat 353 is symmetrically distributed at both ends of the end drive seat 353, which has the advantage of good transmission stability.

[0066] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanation here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
