Description

Technical Field

[0001] This utility model relates to the technical field of combination scales, and in particular to a visual material sorting combination scale. Background Technology

[0002] Existing combined scales generally include a main vibrating plate, multiple linear vibrating plates circumferentially distributed around the main vibrating plate, a storage hopper located below the discharge end of each linear vibrating plate, a weighing hopper located below each storage hopper, and a collection hopper to receive the material output from the multiple storage hoppers. Material placed on the main vibrating plate is conveyed to each linear vibrating plate via vibration. The linear vibrating plates then convey the material to each storage hopper, which in turn discharges the material into the collection hopper. The weighing hopper weighs the material. When the sum of the weights of the materials in the multiple weighing hoppers equals a set weight, the multiple weighing hoppers simultaneously discharge material into the collection hopper, from which it is output from below. While this type of combined scale can meet the usage requirements, some problems exist in actual use, such as the vibration output of the main vibrating plate... After the material enters each vibratory feeder, some feeders receive more material than others. When the feeders need to output material into the hopper, all feeders start simultaneously for a set time to output material. However, if a feeder that receives less material stops just as it reaches the output end after its set time, it may fail to output any material, and the hopper will not receive any material, thus affecting the efficiency of the combined scale. In addition, the overlapping edges between adjacent feeders create gaps, which may cause material jamming during transport, also affecting the efficiency of the combined scale. Therefore, designing a visual material distribution combined scale that can improve the combined efficiency has become an urgent technical problem to be solved. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide a visual material sorting combination scale to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] According to one aspect of this utility model, a visual material sorting combination scale is designed, comprising: a main vibrating plate mounted on a frame, multiple linear vibrating plates circumferentially distributed around the main vibrating plate, a CCD camera disposed above the linear vibrating plates, a storage hopper disposed below the discharge end of each linear vibrating plate, a weighing hopper disposed below each storage hopper, a collection hopper for receiving materials output from the multiple storage hoppers, and a control device. The main vibrating plate, linear vibrating plates, and CCD camera are all electrically connected to the control device. The CCD camera is used to scan the material status on the multiple linear vibrating plates and feed back the material status information to the control device, so that the control device can control one or more linear vibrating plates to start so that the material on them is conveyed to their output end, and control the linear vibrating plate at the jamming position to increase the amplitude.

[0006] Using the above technical solution, when there is material in the weighing hopper and storage hopper and they are waiting to be combined, the CCD camera can scan the material status on each vibrating plate and feed the status information back to the control device. When the control device analyzes that the material on one or more vibrating plates is not at its discharge end, the control device controls the one or more vibrating plates to start and move the material to the discharge end, so that the material can be smoothly output after the vibrating plate starts again, thereby improving the material combination efficiency of the combined scale. When the control device analyzes that the material status on one or more vibrating plates is the same as before and has not changed, that is, it is determined that one or more vibrating plates are jammed, the control device controls the vibrating plate that is jammed to increase its amplitude or controls the vibrating plate that is jammed and the vibrating plates on both sides to increase their amplitude simultaneously, so that the material is smoothly conveyed, the jamming problem is solved, and the efficiency of the combined scale is improved.

[0007] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0008] In some embodiments, the CCD camera is mounted on a camera mount, which is connected to the frame via a support rod.

[0009] In some embodiments, the CCD camera is provided in two, with one CCD camera scanning half of the plurality of linear oscillators and the other CCD camera scanning the other portion of the plurality of linear oscillators.

[0010] In some embodiments, a feeding reminder device is installed on the frame. The feeding reminder device is electrically connected to the control device. When the material status information received by the control device includes multiple linear vibratory feeders with no material, it controls the feeding reminder device to start.

[0011] In some implementations, the control device is an industrial control integrated computer. Attached Figure Description

[0019] refer to Figures 1 to 2 As shown, the present invention provides a visual material sorting combination scale, comprising: a main vibrating plate 2 mounted on a frame 1, multiple linear vibrating plates 3 circumferentially distributed around the main vibrating plate 2, a CCD camera 4 positioned above the linear vibrating plates 3, a storage hopper 5 positioned below the discharge end of each linear vibrating plate 3, a weighing hopper 6 positioned below each storage hopper 5, a collection hopper 7 for receiving materials output from the multiple storage hoppers 5, and a control device. The collection hopper 7 is connected to the frame 1, and the collection hopper 7 is conical with a discharge port at the bottom.

[0020] The linear vibrating plate 3 has three, four, five, six or more circumferences. In this embodiment, it is preferred that the linear vibrating plate 3 has fourteen circumferences. The linear vibrating plate 3 is connected to the frame 1.

[0021] One, two, or more CCD cameras 4 are provided. One CCD camera 4 scans up to eight adjacent line vibrating disks 3. The number of CCD cameras 4 is determined according to the number of line vibrating disks 3. In this embodiment, two CCD cameras 4 are preferably provided. One CCD camera 4 scans seven adjacent line vibrating disks 3, and the other CCD camera 4 scans the other seven line vibrating disks 3. The CCD cameras 4 are mounted on camera mounting parts 41. Camera mounting parts 41 are fixedly connected to support rods 42, and support rods 42 are fixedly connected to the frame 1.

[0022] The storage hopper 5 is a conventional storage hopper. The storage hopper 5 is connected to the frame 1. The gate at the lower end of the storage hopper 5 is controlled to open and close by the drive device on it to realize material feeding and stop feeding. The drive device on the storage hopper 5 is electrically connected to the control device and is controlled by the control device.

[0023] Weighing hopper 6 is a conventional weighing hopper. Weighing hopper 6 is connected to frame 1. The gate at the lower end of weighing hopper 6 is controlled to open and close by a drive device on it to realize material feeding and stop feeding. The drive device on weighing hopper 6 is electrically connected to the control device and is controlled by the control device.

[0024] The main vibrating plate 2, the linear vibrating plate 3, and the CCD camera 4 are all electrically connected to the control device, which is an industrial control all-in-one machine, a micro-control host, or a PLC controller, etc.

[0025] The CCD camera 4 is used to scan the material status on multiple vibrating discs 3 and feed the material status information back to the control device. This allows the control device to activate one or more vibrating discs 3 to transport the material to their output end, and to control the vibrating disc 3 at the jammed position to increase its amplitude, allowing the material to be released from the jam and transported normally. Furthermore, while the weighing hopper 6 and storage hopper 5 contain material and are waiting for the control device to combine the weights, the CCD camera 4 scans the material status on each vibrating disc 3 and feeds the status information back to the control device. When the control device analyzes that the material on one or more vibrating discs 3 is not at its discharge end position, such as... Figure 2 Material A has three states. The control device controls one or more vibrating discs 3 to start, causing the material to move to the discharge end. The state of the material after moving to the discharge end is as follows: Figure 2 The material A' is in any of the four states; when the control device analyzes that the material state on one or more vibrating discs 3 is the same as before and has not changed, it is determined that a jamming phenomenon has occurred at the position of one or more vibrating discs 3. The control device controls the vibrating disc 3 where the material is jammed to increase its amplitude or controls the vibrating disc 3 where the material is jammed and at least one side of the vibrating disc 3 to increase their amplitude simultaneously, so that the material can be conveyed smoothly.

[0026] A feeding reminder device is installed on the frame 1. The feeding reminder device is electrically connected to the control device. The feeding reminder device is an alarm flashing light and / or a buzzer. When the material status information received by the control device includes that there is no material on two or three or more linear vibrating discs 3, it controls the feeding reminder device to start, and the alarm flashing light flashes and / or the buzzer sounds.

[0027] The principle of this combined scale is as follows: Materials are manually or via a feeding machine conveyed to the main vibrating plate 2. The control device controls the main vibrating plate 2 to vibrate, causing the materials to disperse into multiple linear vibrating plates 3. The multiple linear vibrating plates 3 vibrate to convey the materials into multiple storage hoppers 5. After the main vibrating plate 2 and linear vibrating plates 3 start for a set time, they stop. The drive devices on the multiple storage hoppers 5 drive their lower gates to open, allowing the materials to be discharged into the weighing hopper 6. After that, the gate closes. The weighing sensors on the weighing hopper 6 feed back the weighing information to the control device. When the combined scale needs to output a set weight of material, when the control device analyzes that the sum of the weights of the materials in several weighing hoppers 6 equals the set weight of the material, the control device controls the drive devices on those several weighing hoppers 6 to open their lower gates according to the set weighing command, allowing the materials to be discharged into the collection hopper 7 and discharged from the outlet at the bottom of the collection hopper 7. After that, the gate on the weighing hopper 6 closes.

[0028] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
