Description

Technical Field

[0001] The invention relates to the technical field of industrial parts weighing equipment, in particular to a heavy-weight parts conveying and weighing device. Background Art

[0002] Parts weighing is a common pre-processing method in the manufacturing industry. It uses a metering device to weigh a certain number of parts and discharges the parts when the weight reaches a preset value, thereby achieving precise control of the number of parts.

[0003] Chinese patent document CN218079089U discloses a parts weighing automatic sorting device, which uses a gravity sensor and a weighing table to calculate the total weight of a certain number of parts, and outputs the parts that reach the preset weight from the weighing table through a flap. Although this automatic sorting device can realize automatic weighing and output of parts, the continuity of the input sorting device before the parts are weighed is extremely poor, and it cannot meet the requirements of automatic transportation, weighing, and output. At the same time, although it outputs parts that reach the preset weight through a flap, there is a quantitative error in the input of the parts itself during weighing, so its weighing accuracy is poor.

[0004] The Chinese patent document CN217675001U discloses a vibration plate conveying device, which automatically conveys parts along the feed track and the straight vibration track through the cooperation of the vibration plate and the straight vibration base. Although the vibration plate conveying device can automatically convey parts, the disadvantages of vibration conveying are also very obvious. First, the weight and volume of the parts conveyed by vibration cannot be too large, otherwise the vibration conveying cannot make the parts detach from the vibration plate and the parts cannot be conveyed at all. Second, the vibration conveying track in the vibration plate needs to be laid for a certain length, which will not only increase the floor space of the conveying equipment itself, but also weaken the stability of the vibration conveying.

[0005] Therefore, how to achieve stable transportation of heavy parts while accurately weighing and outputting them is a major technical challenge in automated production. Summary of the invention

[0006] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a heavy-weight parts conveying and weighing device with small volume and accurate weighing.

[0007] The present invention provides a heavy-weight parts conveying and weighing device, which mainly comprises a feeding mechanism, a conveying mechanism, a weighing mechanism and a collecting mechanism which are respectively arranged on a frame and arranged in a stepped manner from top to bottom, a material blocking mechanism is arranged between the feeding mechanism and the conveying mechanism, the conveying mechanism comprises a main conveying assembly and a replenishing conveying assembly which are arranged in the same direction, and the weighing mechanism comprises a main weighing assembly and a replenishing weighing assembly, so that heavy parts can be weighed according to quantity during short-distance transportation and the accuracy of the weighing process can be ensured.

[0008] By optimizing the above structure, the feeding mechanism includes a feeding seat located on the frame, a feeding conveyor belt arranged in the feeding seat, a feeding motor connected to the feeding conveyor belt, and a feeding channel arranged at the end of the feeding seat.

[0009] By further improving the above structure, the loading conveyor belt is arranged to be tilted upward along the conveying direction to ensure that the parts are not affected by their own gravity and fall in the direction of the conveying mechanism.

[0010] By optimizing the above structure, the main conveying assembly includes a conveying seat located on the frame, a main conveying belt arranged in the conveying seat, and a main conveying motor connected to the main conveying belt, and the main conveying belt corresponds to the exit position of the feeding mechanism.

[0011] By further improving the above structure, the feeding conveying assembly includes a feeding conveying belt arranged in the conveying seat and a feeding motor connected to the feeding conveying belt. The feeding conveying belt corresponds to the outlet of the feeding mechanism and the position of the blocking mechanism respectively.

[0012] By further improving the above structure, a material shifting plate is provided on the side wall of the conveying seat, which corresponds to the position of the feeding conveyor belt and can rebound after being stressed, so as to shift them to the main conveyor belt when the number of parts is large.

[0013] By optimizing the above structure, the main weighing assembly includes a first weighing bucket arranged on the frame and corresponding to the position of the main conveying assembly, a first baffle movably hinged to the first weighing bucket, and a first driving cylinder arranged on the first weighing bucket and connected to the first baffle, and a meter is provided on the first weighing bucket.

[0014] By further improving the above structure, the feeding weighing assembly includes a second weighing bucket fixed on the first weighing bucket and corresponding to the position of the feeding conveying assembly, a second baffle movably hinged to the second weighing bucket, and a second driving cylinder arranged on the second weighing bucket and connected to the second baffle.

[0015] By optimizing the above structure, a lower hopper which can move back and forth in the vertical direction is provided below the collecting mechanism to discharge the parts after being weighed and collected.

[0016] By optimizing the above structure, a lifting cylinder is provided on the frame, and a bracket fixedly connected to the piston rod of the lifting cylinder is provided on the lower hopper, so that the lower hopper can adapt to collection scenes at different heights.

[0017] The beneficial effects of the heavy-weight parts conveying and weighing device of the present invention are:

[0018] 1. The heavy-weight parts conveying and weighing device of the present invention adopts a structure of continuous step-by-step conveying and zoned weighing to realize automatic conveying, weighing and unloading of heavy-weight parts. First, the step-by-step conveying structure can make full use of the large weight of the parts themselves, without the need for vibrating transmission of the parts, thus reducing the floor space occupied by the conveying and weighing device. Especially for assembled parts, step-by-step conveying can completely prevent the loosening or even separation of parts due to constant vibration during transmission, thereby improving the stability and reliability of part transmission. Secondly, zoned weighing can ensure the accuracy of the total weight when the parts are unloaded, and avoid errors in the total weight caused by excessive transmission speed of the parts.

[0019] 2. In the heavy-weight parts conveying and weighing device of the present invention, the conveying mechanism includes a main conveying component and a feeding conveying component, and the weighing mechanism includes a main weighing component and a feeding weighing component. This structure can separate the transmission and weighing of parts into two independent processes. In addition to ensuring the coordination between the two operations of transmission and weighing, it also improves the stability and accuracy of the total weight measurement of parts.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The following embodiments are one or several examples that can realize the new technical solutions of the present utility model, obtain corresponding technical effects, and solve corresponding technical problems, and do not mean that the protection scope of the technical solutions only includes the following embodiments.

[0033] according to Figure 1 As shown, the heavy-weight parts conveying and weighing device of the present invention mainly includes a frame 1, a feeding mechanism 2, a conveying mechanism 4, a weighing mechanism 5 and a collecting mechanism 6. The feeding mechanism 2, the conveying mechanism 4, the weighing mechanism 5 and the collecting mechanism 6 are all fixedly arranged on the frame 1, and are arranged in a stepped manner from top to bottom. A circuit controller is also installed in the frame 1, and the feeding mechanism 2, the conveying mechanism 4, the weighing mechanism 5 and the collecting mechanism 6 are all electrically connected to the circuit controller to realize that the parts pass through the above mechanisms in sequence under the action of their own gravity during transmission. The conveying mechanism 4 is composed of a main conveying component and a replenishing conveying component. The main conveying component and the replenishing conveying component are arranged in the same direction on the frame 1 to ensure that the transmission direction of the parts is consistent, and the two can operate independently to ensure that the transmission of the parts on the two does not interfere with each other. The weighing mechanism 5 is composed of a main weighing component and a replenishing weighing component, and the two can also operate independently. There is also a material blocking mechanism between the feeding mechanism 2 and the conveying mechanism 4, which is fixedly arranged on the frame 1 to control the parts to enter the main conveying assembly or the supplementary conveying assembly. The collecting mechanism 6 is located below the weighing mechanism 5, which collects the parts output from the main weighing assembly and the supplementary weighing assembly. There are at least two conveying mechanisms 4, material blocking mechanisms, weighing mechanisms 5 and collecting mechanisms 6 on the frame 1 and they are arranged in parallel to improve the working efficiency of the conveying and weighing device.

[0034] according to Figure 2 , Figure 3As shown, in one embodiment of the present invention, the feeding mechanism 2 includes a feeding seat 21, a feeding conveyor belt 22, a feeding motor 23 and a feeding channel 24. The feeding seat 21 is located on the frame 1 and is fixed to the frame 1. The feeding conveyor belt 22 is located in the feeding seat 21, and can continuously push the parts forward when it is working. The feeding motor 23 is also located on the frame 1 and is also fixed to the frame 1. The feeding motor 23 is connected to the feeding conveyor belt 22, specifically, the feeding conveyor belt 22 is sleeved on the output shaft of the feeding motor 23, so that the feeding motor 23 can drive the feeding conveyor belt 22 to rotate synchronously when it is working. The feeding channel 24 is located at the end on the other side of the feeding seat 21 relative to the outlet, and is fixed to the frame 1 to realize the input of parts from the feeding channel 24 to the feeding conveyor belt 22.

[0035] In another embodiment, the loading conveyor belt 22 is inclined along the conveying direction of the parts, specifically, the outlet of the loading conveyor belt 22 is higher than the inlet in the vertical direction. In addition to preventing the parts from rolling in the loading conveyor belt 22 due to their own gravity during transportation, this structure can also prevent the parts from accumulating at a certain place of the loading conveyor belt 22, thereby ensuring the stability and reliability of the loading conveyor belt 22 in conveying the parts. In addition, there is a supporting roller 25 below the loading conveyor belt 22, which is located below the bottom surface of the loading conveyor belt 22 and is connected to the loading conveyor belt 22 to support the transmission of the loading conveyor belt 22.

[0036] according to Figure 4 As shown, in another embodiment of the present invention, the material blocking mechanism includes a material blocking seat 31, a material blocking cylinder 32 and a material blocking plate 33. The material blocking seat 31 is located on the frame 1 and fixed to the frame 1. The material blocking seat 31 is arranged to converge inward along the transmission direction of the parts on the frame 1 to ensure that the material blocking plate 33 can contact the parts output from the feeding mechanism 2 in time. The cylinder body of the material blocking cylinder 32 is arranged on the material blocking seat 31, and its piston rod is fixed on the material blocking plate 33, and can drive the material blocking plate 33 to move back and forth when the cylinder body is working. There is also a material stopping slider 34 and a material stopping slide rail 35 between the material stopping seat 31 and the material stopping plate 33. The settings of the two on the material stopping seat 31 and the material stopping plate 33 can be selected according to actual needs. The sliding mechanism composed of the material stopping slider 34 and the material stopping slide rail 35 has the same movement direction as the piston rod of the material stopping cylinder 32 to improve the stability of the movement of the material stopping plate 33 and prevent parts from continuously hitting the material stopping plate 33 and affecting the normal operation of the material stopping cylinder 32.

[0037] according to Figure 5 , Figure 6As shown, in one embodiment of the present invention, the main conveying assembly includes a conveying seat 41, a main conveying belt 42 and a main conveying motor 43. The conveying seat 41 is located on the frame 1 and is fixed to the frame 1. The main conveying belt 42 is arranged in the conveying seat 41, and can continuously push the parts forward when it is working. The main conveying motor 43 is connected with the main conveying belt 42, specifically, the main conveying belt 42 is sleeved on the output shaft of the main conveying motor 43, so that the main conveying motor 43 can drive the main conveying belt 42 to rotate synchronously when it is working. The main conveying belt 42 corresponds to the outlet position of the feeding mechanism 2, specifically, the entrance of the main conveying belt 42 is located below the outlet of the feeding conveyor belt 22. In addition, a guide plate 44 is also provided on the outer side of the outlet of the main conveying belt 42, and the guide plate 44 is arranged on the conveying seat 41 and is movably hinged with the conveying seat 41. A material guide cylinder 45 is also provided on the conveying seat 41. The cylinder body of the material guide cylinder 45 is connected to the conveying seat 41, and its piston rod is connected to the material guide plate 44. When the material guide cylinder 45 is working, it can push the material guide plate 44 to rotate on the conveying seat 41, thereby adjusting the gap of parts output from the main conveyor belt 42 to avoid multiple parts being stacked and output.

[0038] In another embodiment, the feeding conveying assembly includes a feeding conveyor belt 47 and a feeding motor 48. The feeding conveyor belt 47 is arranged in the conveying seat 41, and can continuously push the parts forward when it is working. The feeding conveying motor is connected with the feeding conveyor belt 47, specifically, the feeding conveyor belt 47 is sleeved on the output shaft of the feeding conveying motor, so that the feeding conveying motor can drive the feeding conveyor belt 47 to rotate synchronously when it is working. The feeding conveyor belt 47 corresponds to the outlet of the feeding mechanism 2 and the position of the material blocking mechanism respectively, specifically, the inlet of the feeding conveyor belt 47 is located below the outlet of the feeding conveyor belt 22, and corresponds to the position of the moving end of the material blocking mechanism.

[0039] In another embodiment, the side wall of the conveying seat 41 is further provided with a material shifting plate 46. The material shifting plate 46 is located on the transmission path of the replenishing conveyor belt 47, and adopts an elastic mechanism that can rebound after being stressed, so that the material shifting plate 46 can reset after shifting the parts into the main conveyor belt 42.

[0040] according to Figure 7 , Figure 8As shown, in another embodiment of the present invention, the main weighing assembly includes a first weighing bucket 51, a first baffle 52, a first driving cylinder 53 and a meter 54. The first weighing bucket 51 is arranged on the frame 1 and is fixedly connected to the frame 1. At the same time, the first weighing bucket 51 corresponds to the outlet position of the main conveying assembly, specifically, the outlet of the main conveying belt 42, so as to receive the parts transmitted from the main conveying belt 42. The first baffle 52 and the first driving cylinder 53 are both connected to the first weighing bucket 51, wherein the first baffle 52 is movably hinged with the first weighing bucket 51 to realize the opening or closing of the first weighing bucket 51; the cylinder body of the first driving cylinder 53 is connected to the first weighing bucket 51, and its piston rod is connected to the first baffle 52 to realize the rotation of the first baffle 52 on the first weighing bucket 51 when it is working. The meter 54 is also arranged on the first weighing bucket 51 and is fixed to the first weighing bucket 51. It can use a commercially available electronic scale or other weight measuring device to calculate the total weight of the parts in the first weighing bucket 51.

[0041] In another embodiment, the refill weighing assembly includes a second weighing hopper 55, a second baffle 56 and a second drive cylinder 57. The second weighing hopper 55 is fixed to the first weighing hopper 51 and corresponds to the outlet position of the refill conveying assembly, specifically, the outlet of the refill conveying belt 47, so as to receive the parts transmitted from the refill conveying belt 47. The second baffle 56 is connected to the second weighing hopper 55 and is movably hinged with the second weighing hopper 55 to realize the opening or closing of the second weighing hopper 55. The cylinder body of the second drive cylinder 57 is connected to the second baffle 56, and its piston rod is connected to the second weighing hopper 55, so as to realize the rotation of the second baffle 56 on the second weighing hopper 55 when it is working.

[0042] according to Fig. 9 , Fig.10 As shown, in another embodiment of the present invention, the material collecting mechanism 6 includes a material collecting hopper 61, a material collecting baffle 62 and a material collecting cylinder 63. The material collecting hopper 61 is fixed on the frame 1, and is located below the weighing mechanism 5, specifically below the first weighing hopper 51 and the second weighing hopper 55, so as to collect the parts output from the first weighing hopper 51 and the second weighing hopper 55. The material collecting baffle 62 is movably hinged on the material collecting hopper 61, and the material collecting hopper 61 can be opened or closed when it rotates. The cylinder body of the material collecting cylinder 63 is arranged on the material collecting hopper 61, and its piston rod is connected to the material collecting baffle 62, so as to realize the rotation of the material collecting baffle 62 on the material collecting hopper 61 when it is working.

[0043] according to Fig.11 As shown, in another embodiment of the present invention, a lower hopper 71 is further provided below the material collecting mechanism 6. The lower hopper 71 is located below the material collecting mechanism 6 and can move back and forth in the vertical direction to adapt to the discharge height of different parts.

[0044] In another embodiment, the frame 1 is further provided with a lifting cylinder 72. The cylinder body of the lifting cylinder 72 is fixed on the frame 1, and a bracket 73 is fixedly provided on the piston rod thereof. The bracket 73 is connected to the lower hopper 71 to drive the lower hopper 71 to move up and down when the lifting cylinder 72 is working.

[0045] When the heavy-weight parts conveying and weighing device of the present invention is working, the parts are input from the feeding channel 24 to the feeding conveyor belt 22, and the feeding conveyor belt 22 is driven by the feeding motor 23 to transport the parts forward, and output from the outlet of the feeding conveyor belt 22. When the number of parts is large and stacked, they will contact the baffle plate 33 during the output process, and enter the feeding conveyor belt 47 under the blocking effect of the baffle plate 33. The feeding conveying motor drives the feeding conveyor belt 47 to transport the parts forward. The position of the baffle plate 33 is controlled by the movement of the baffle cylinder 32, and the axial reciprocating movement of the baffle plate 33 in the piston rod of the baffle cylinder 32 is realized by the sliding cooperation between the baffle slider 34 and the baffle rail 35. When the parts on the feeding conveyor belt 47 are being transported, the parts will judge whether the number of parts on the feeding conveyor belt 47 is too much through the elastic blocking effect of the material stripping plate 46. When there are fewer parts on the feeding conveyor belt 47, they enter the main conveyor belt 42 under the blocking of the material stripping plate 46; and when there are more parts on the feeding conveyor belt 47, they push the material stripping plate 46 away and continue to be transported on the feeding conveyor belt 47. When the number of parts output from the outlet of the feeding conveyor belt 22 is small, they directly enter the main conveyor belt 42 from the outlet of the feeding conveyor belt 22, and are continuously transported forward under the drive of the main conveying motor 43. At the outlet of the main conveyor belt 42, the parts enter the first weighing bucket 51 under the guidance of the material guide plate 44, and at the outlet of the feeding conveyor belt 47, the parts directly enter the second weighing bucket 55. The position of the material guide plate 44 can be adjusted by the material guide cylinder 45 to accommodate parts of different sizes. The total weight of the parts in the first weighing hopper 51 and the second weighing hopper 55 is weighed by the meter 54, and when the predetermined weight is reached, the first baffle 52 is opened by the first driving cylinder 53, and the second baffle 56 is opened by the second driving cylinder 57, so that the parts enter the collecting hopper 61. The collecting baffle 62 is opened by the collecting cylinder 63, and the parts can enter the lower hopper 71 and be output after the collection is completed.

[0046] The above specific embodiments are only implementation methods with better technical effects of the present invention.
