Description

Technical Field

[0001] The utility model belongs to the technical field of packaging weighing, in particular to an intelligent weighing mechanism. Background Art

[0002] As we all know, there are increasing orders for fresh pork bone products that require fixed weights. Manual weighing is difficult for the following reasons: ① To ensure quality, bone products must maintain bone integrity, so they cannot be cut. Bone products have a low meat content, and if the target weight is not reached, it is difficult to complete the weighing by cutting the meat. This requires repeated material changes, which is time-consuming. ② Products such as spare ribs, front and back legs, front and back hams weigh between 1kg and 2kg each. For example, weighing 10kg requires 6-10 pieces, which increases the difficulty of weighing.

[0003] Through research, we found that there is no fresh pig bone weighing equipment on the market. Existing fish, agricultural products, and powder weighing equipment cannot be applied to fresh pig bone weighing products. The main reasons are as follows:

[0004] 1. The equipment specifications and sizes do not match. The size of fresh pork bones is relatively large, and the length of the spine and hind leg bones is between 300mm and 500mm.

[0005] 2. Because fresh pork bone products are large in size and irregular in shape, the existing weighing equipment on the market has the disadvantage of being easily stuck.

[0006] Given the irregular shape of fresh pork bones, there is no viable automated loading solution on the market. Therefore, designing a device to replace manual weighing, improve overall efficiency, and reduce labor intensity has become a key research topic in the existing technology. Utility Model Content

[0007] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides an intelligent weighing mechanism to solve the above-mentioned problems.

[0008] To achieve the above-mentioned purpose, the utility model discloses an intelligent weighing mechanism, comprising:

[0009] A loading module, comprising a lever mechanism, a product outflow channel, and a first conveying mechanism. The first conveying mechanism is provided with a rotatable lever mechanism, the lever mechanism being used to shift the material on the first conveying mechanism to the product outflow channel. A weighing module is provided below the outlet of the product outflow channel.

[0010] The weighing module is used to weigh the material. There are multiple weighing modules, and the multiple weighing modules are used to transport the weighed material to the second conveying mechanism according to the specified weight requirements.

[0011] Compared with the prior art, the present application has the following effects: first, the material is placed on the first conveying mechanism, and the material is moved by the first conveying mechanism. When the material moves to the specified position, the lever mechanism works to shift the material into the product outflow channel. Under the guidance of the product outflow channel, the material falls onto multiple weighing modules; then, the material is weighed on the weighing module, and the multiple weighing modules display their respective weights; finally, the multiple weighing modules give a material unloading plan according to the specified weight requirements, ensuring that the weight of the materials conveyed by the multiple weighing modules is equal to the specified weight requirements, and conveying the materials to the second conveying mechanism, and conveying the materials to the specified position through the second conveying mechanism. Therefore, the present application replaces manual weighing and realizes simultaneous batching through multiple weighing modules, which not only improves the overall efficiency of fresh pork bone weighing, but also reduces labor intensity.

[0012] Furthermore, the weighing modules are symmetrically arranged on both sides of the first conveying mechanism.

[0013] Furthermore, the number of the weighing modules is 16.

[0014] Furthermore, the weighing module includes a weighing frame, a weighing platform, a cylinder and a weighing sensor. One end of the weighing frame is hinged to the weighing platform through a rotating shaft, and the other end is connected to the weighing sensor. The cylinder is connected to the rotating shaft to drive the rotating shaft to rotate, thereby driving the weighing platform to flip.

[0015] Furthermore, or the weighing module includes a belt scale, and the second conveying mechanism is provided below the outlet of the belt scale.

[0016] Furthermore, the first conveying mechanism includes a horizontal belt conveyor, which is used to convey materials horizontally.

[0017] Furthermore, the first conveying mechanism also includes an inclined belt conveyor arranged on one side of the horizontal belt conveyor, and the outlet of the inclined belt conveyor is arranged above the horizontal belt conveyor.

[0018] Furthermore, the shifting rod mechanism includes a shifting rod, a crank arm and a cylinder, and the cylinder drives the crank arm to move the shifting rod to shift the material on the first conveying mechanism into the product outflow channel.

[0019] Furthermore, it also includes a control system. The first conveying mechanism is provided with a photoelectric sensor for detecting the passage of materials. The lever mechanism, the photoelectric sensor, and the first conveying mechanism are all electrically connected to the control system. The control system controls the operation of the lever mechanism and the first conveying mechanism based on the signal feedback from the photoelectric sensor.

[0020] Furthermore, the control system is electrically connected to the weighing module and the second conveying mechanism respectively, and the control system controls the weighing module and the second conveying mechanism to operate according to a signal fed back by the weighing module.

[0027] 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. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figure 1-3As shown, the utility model discloses an intelligent weighing mechanism, comprising:

[0029] The loading module includes a lever mechanism 1, a product outflow channel 2, and a first conveying mechanism 3. The first conveying mechanism 3 is provided with a rotatable lever mechanism 1, which is used to shift the material on the first conveying mechanism 3 to the product outflow channel 2. A weighing module 4 is provided below the outlet of the product outflow channel 2;

[0030] The weighing module 4 is used to weigh the material. There are multiple weighing modules 4 , and the multiple weighing modules 4 are used to transport the weighed material to the second conveying mechanism 5 according to the specified weight requirement.

[0031] Compared with the prior art, the present application has the following effects: first, the material is placed on the first conveying mechanism 3, and the material is moved by the first conveying mechanism 3. When the material moves to the specified position, the lever mechanism 1 works to shift the material into the product outflow channel 2. Under the guidance of the product outflow channel 2, the material falls onto multiple weighing modules 4; then, the material is weighed on the weighing module 4, and the multiple weighing modules 4 display their respective weights; finally, the multiple weighing modules 4 provide a material unloading plan according to the specified weight requirements, ensuring that the weight of the materials conveyed by the multiple weighing modules 4 is equal to the specified weight requirements, and convey the material to the second conveying mechanism 5, and the material is conveyed to the specified position by the second conveying mechanism 5. Therefore, the present application replaces manual weighing and realizes simultaneous batching through multiple weighing modules 4, which not only improves the overall efficiency of fresh pork bone weighing, but also reduces labor intensity.

[0032] Continuing with the above embodiment, more specifically, the weighing modules 4 are symmetrically arranged on both sides of the first conveying mechanism 3. The weighing modules 4 are designed in a double-row linear shape, which saves space to a certain extent and better receives the materials transferred by the first conveying mechanism 3.

[0033] Continuing with the above embodiment, more specifically, the number of weighing modules 4 is 16. Based on the weight characteristics of the material, 16 weighing modules 4 are designed to ensure that multiple weighing modules 4 are combined to achieve successful weight balancing. Each weighing module 4 can work independently. If too many weighing modules 4 are provided, the cost will inevitably be too high. If too few are provided, weight balancing may fail.

[0034] Following the above embodiment, more specifically, in one embodiment, Figure 2As shown, the weighing module 4 includes a weighing frame 6, a weighing platform 7, a cylinder 8, and a weighing sensor 9. One end of the weighing frame 6 is hinged to the weighing platform 7 via a rotating shaft, and the other end is connected to the weighing sensor 9. The cylinder 8 is connected to the rotating shaft, which is used to drive the rotating shaft to rotate and thus drive the weighing platform 7 to flip. The cylinder 6 extends and retracts to drive the weighing platform 7 to rotate via the rotating shaft, thereby flipping the material on the weighing platform 7 onto the second conveying mechanism 5.

[0035] Continuing with the above embodiment, more specifically, the first conveying mechanism 3 includes a horizontal belt conveyor 11, which is used to convey materials in horizontal motion.

[0036] In another embodiment, Figure 3 As shown, the weighing module 4 includes a belt scale 10 , and a second conveying mechanism 5 is provided below the outlet of the belt scale 10 . The belt scale 10 has weighing and conveying functions, completes the weighing of materials, and conveys the materials to the second conveying mechanism 5 .

[0037] Continuing with the above embodiment, more specifically, the first conveying mechanism 3 further includes an inclined belt conveyor 12 disposed on one side of the horizontal belt conveyor 11, with the outlet of the inclined belt conveyor 12 disposed above the horizontal belt conveyor 11. The design of the inclined belt conveyor 12 eliminates the need for operators to lift materials onto the relatively high horizontal belt conveyor 11, thereby significantly reducing the workload of operators.

[0038] Continuing with the above embodiment, more specifically, the lever mechanism 1 includes a lever 14 , a crank arm 13 and a cylinder 8 . The cylinder 8 drives the crank arm 13 to move the lever 14 to move the material on the first conveying mechanism 3 into the product outflow channel 2 .

[0039] Continuing with the above embodiment, it is more preferred that, in order to achieve automated control of the entire apparatus, a control system be further included. A photoelectric sensor 15 is provided on the first conveying mechanism 3 for detecting the passage of material. The lever mechanism 1, the photoelectric sensor 15, and the first conveying mechanism 3 are all electrically connected to the control system. The control system controls the operation of the lever mechanism 1 and the first conveying mechanism 3 based on signals fed back by the photoelectric sensor 15. The photoelectric sensor 15 is provided at the feed end of the first conveying mechanism 3. When material passes through the photoelectric sensor 15, it feeds back a signal to the control system. The control system calculates the position of the material within the first conveying mechanism 3 based on the conveying speed of the first conveying mechanism 3 and the time since the material passed the photoelectric sensor 15. The control system then controls the lever mechanism 1 to divert the material into the designated product outflow channel 2.

[0040] Continuing with the above embodiment, more specifically, the control system is electrically connected to the weighing module 4 and the second conveying mechanism 5, respectively. The control system controls the operation of the weighing module 4 and the second conveying mechanism 5 based on the signals fed back by the weighing module 4. Specifically, the weighing modules 4 feed back their respective temporarily stored material weight signals to the control system. The control system then generates a weight distribution plan based on a preset weight standard, and then controls the weighing modules 4 to discharge the material onto the second conveying mechanism 5. It should be noted that if the weighing modules 4 cannot be matched to meet the required weight standard, the control system preferentially discharges the material in the heaviest weighing modules 4 onto the second conveying mechanism 5. The second conveying mechanism 5 then reverses the direction of transport and delivers the material to the designated area. Simultaneously, the material is re-fed into the weighing modules 4 that have already discharged material.

[0041] The working process of this equipment is:

[0042] First, a person stands at the rightmost end of the first conveying mechanism 3 and places the materials in order. The materials are transported to the top of the weighing module 4 through the conveyor belt of the first conveying mechanism 3. Then, the materials are transferred to the corresponding vacant weighing platform 7 in order through the lever 14. After the weighing platform 7 is filled with materials, each weighing platform 7 reads the product weight, and the control system calculates and combines it into the value closest to the target weight requirement of the product (such as 10kg / 15kg, and the error is within the range of 0-20g for successful weight balance). Finally, the control system controls the weighing platform 7 to flip inward, and the materials fall onto the conveyor belt of the second conveying mechanism 5 and are transported to the finished product discharge port. Among them, if the difference in the weighing results is large, greater than 20g, the six weighing platforms 7 with larger weights will flip inward, and the conveyor belt of the second conveying mechanism 5 will run in the opposite direction to discharge the materials from the rejection port. Then the lever 14 will load the materials at the position of the weighing platform 7 where the materials are vacant until the weighing is successful.

[0043] It should be noted that the control system is a PLC controller, a digital computing and operating electronic system designed specifically for use in industrial environments. It uses a programmable memory to store instructions for performing operations such as logic operations, sequential control, timing, counting, and arithmetic operations. It controls various types of mechanical equipment or production processes through digital or analog input and output.

[0044] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
