In the prior art, an automatic weighing machine is generally arranged at the middle position of a section of production line and is provided with a conveying belt, the conveying belt rotates to convey articles, two ends of the upper surface of the conveying belt are respectively connected with the production line, the weighing principle is that a weight sensor is basically arranged below the conveying belt, the weight sensor detects the weight change of the whole conveying belt and then transmits the weight change to a computer weight signal, the weight sensor is basically a pressure change type sensor, the weight sensor moves downwards for a certain distance when receiving gravity and sends an electric signal outwards, when the articles on the production line enter the automatic weighing machine, a support part changes, and the weight sensor falls for a certain distance to detect, so that the vibration of a measuring section can be caused when the articles enter the measuring section and are separated from the measuring section, therefore, the length of the measuring section is larger than a certain multiple of the length and the size of the articles to eliminate the influence of, the measuring section is longer, influences the space utilization of assembly line, can only measure an article simultaneously in the measuring section, that is to say the interval of article on the assembly line will be great, will influence the packing efficiency of commodity like this again, moreover, can't use same automatic weighing machine to the commodity of different length size, because if regard as the lectotype standard with the longest length possible, then can further cut down when weighing to the small-size article and produce line efficiency and space utilization, this is too unacceptable.
Disclosure of Invention
The invention aims to provide a full-automatic high-precision dynamic electronic weighing device to solve the problems in the prior art.
In order to achieve the purpose, the invention provides the following technical scheme:
the utility model provides a full-automatic high accuracy developments electronic weighing device, includes conveyer belt, collet subassembly, a plurality of supporting component and signal line, and the conveyer belt covers at the upper surface of supporting component, and the supporting component is installed on the collet subassembly, and the supporting component loads on the collet subassembly with the weight of article on the conveyer belt, and collet subassembly passes through the signal line and outwards transmits the weight signal.
A plurality of supporting components installed on the bottom support component are individual weight measuring components, the conveying belt is a belt used for placing articles, the belt is not in a very tight state as usual, but is in a slightly loose state, the conveying belt in the loose state only pulls the articles to move forwards, and the weight of the articles is loaded on the supporting components when passing through the supporting components, so that the gravity of the articles can be considered as the gravity of the articles by the stress of the vertical direction of the supporting components, and the supporting components transmit the gravity to the external monitor through the bottom support component and the signal wire to record the weight information of the articles.
If the individual goods on a production line are weighed, the conveyor belt can directly use the belt on the original conveying line, but it should be noted that the related structural modification should be carried out on the original conveyor belt, so that the weight of the goods on the belt is transferred to the supporting component when the goods pass through the supporting component; for the weighing of commodities in a product line, the supporting component used by the invention can carry out synchronous multi-station measurement on a section of the product line, the supporting component of an article at different positions can also be subjected to multiple times of weighing, a plurality of data are mutually calibrated, if one supporting component deviates from other data, a manager is prompted to check the installation relationship between the supporting component and the bottom support component and whether an electrical component is in fault, the measurement accuracy and precision are improved, the continuity is good, and the article only needs to be separated by a distance which exceeds the distance between two supporting components.
It can be that supporting component is alone as the check weighing part, and the collet subassembly only provides the mounted position as rigid support for supporting component, supporting component can use traditional pressure sensor this moment, devices such as weight sensor carry out power-electricity signal conversion, this moment, because the principle of weighing of device, article can be difficult to the certain distance of whereabouts of avoiding when flowing through supporting component, weight is big more, article push down supporting component's distance is also big more, thereby the deformation of conveyer belt is also big more, the conveyer belt of department of weighing is recessed serious, can produce with front and back conveyer belt and drag, cause weighing of power to take place proportional skew, need carry out the later stage according to article weight after signal transmission comes out and revise, this kind of mode is comparatively troublesome.
Still another mode is weighed through the linkage of supporting component and collet subassembly, be connected not rigid connection between supporting component and the collet subassembly, but the supporting component becomes suspension state, perhaps the collet subassembly can give the ascending feedback power of supporting component, help the supporting component when receiving article gravity whereabouts, thereby can be once more by upwards jack-up and keep certain high position, article gravity that the supporting component received lets it detect on transmitting the collet subassembly through the form of reaction force, and then convert the signal of telecommunication into and transmit away through the signal line. The height position keeps stable supporting component just can let the conveyer belt also keep certain height position to reduce the deformation of conveyer belt, article also be whole gravity loading when through supporting component on supporting component, thereby weight data does not need the later stage to revise.
Furthermore, the weighing device also comprises a partition plate, the bottom support assembly comprises a track and a supporting electromagnet, and the supporting assembly comprises a supporting block, a supporting permanent magnet, a first limiting permanent magnet and a rolling support;
an inverted T-shaped groove with an upward opening is formed in the rail, a plurality of inserting plate grooves are formed in the rail along the extending direction of the rail, a plurality of supporting electromagnets are arranged on the bottom surface of the T-shaped groove, and the supporting electromagnets are electrically connected with the outside through signal wires; the supporting block is embedded into the T-shaped groove, the supporting permanent magnets are arranged on the bottom surface of the supporting block and are arranged opposite to the supporting electromagnets, a plurality of rolling supports are arranged on the upper surface of the supporting block, the first limiting permanent magnets are arranged on the side surface of the bottom of the supporting block, and the electromagnets opposite to the first limiting permanent magnets are arranged on the wall surface of the T-shaped groove; two adjacent supporting blocks are separated by a partition plate, and the partition plate is inserted into the inserting plate groove.
The signal wire is also used for transmitting exciting current of the supporting electromagnet, the magnetic force of the supporting electromagnet and the supporting permanent magnet is repulsive force, the larger the exciting current of the supporting electromagnet is, the stronger the magnetism of the supporting electromagnet is, so that the lifting force of the supporting electromagnet relative to the supporting permanent magnet is larger, in a conventional state, basic current I1 is introduced into the supporting electromagnet, the current is used for offsetting the self gravity of the supporting assembly, when an article is loaded on the supporting assembly for weighing, the supporting assembly can fall due to the gravity, a position sensor used for detecting the falling position of the supporting assembly is arranged for identifying whether the article is loaded on the supporting assembly, when the supporting assembly falls, the exciting current introduced into the supporting electromagnet is increased until the supporting assembly returns to the original height, at the moment, the current in the supporting electromagnet is I2 which is larger than I1, and the difference value between I2 and I1 is represented as the external magnetic force on the, the difference value delta I can reflect the weight of the object on the supporting component after conversion. If the article flowing on the conveyor belt is a standard article, the weight of the article has a standard value, when the article is loaded on the supporting component, the current on the supporting electromagnet can be directly adjusted to be standard I2, whether the difference value between the weight of the article and the standard weight exceeds the expectation or not is reflected by detecting the difference value between the actual height position and the standard height position of the supporting component, and the external data only needs to indicate whether the weight of the article is qualified or not; if the article is an article without standard weight, the proper current is applied to return the article to the original position by detecting the downward movement of the supporting component, and the external output data is the actual weight of each article, which is slightly more complicated than the previous weighing mode. The partition board is used for separating adjacent supporting assemblies and used as a front-back movement limiting part of the supporting assemblies on the track to prevent the supporting assemblies from displacing along the length direction of the supporting assemblies on the track, the supporting assemblies and the partition board are preferably not contacted, and even if the supporting assemblies are in contact type limiting, acting force and reacting force in the vertical direction should be prevented.
As optimization, the T-shaped groove is filled with deionized water. The T-shaped groove is filled with magnetic induction lines for transmitting acting force between the support component and the bottom support component, so the space of the T-shaped groove is clean and pollution-free, otherwise, after some dust which can be magnetized enters the T-shaped groove, the distribution of the magnetic induction lines is influenced, the weighing is inaccurate, most preferably, a vacuum environment is created in the T-shaped groove, however, because the opening at the upper part of the T-shaped groove is inconvenient to seal, the deionized water is used as a dustproof liquid, the dust falling from the outside can only float on the liquid level of the deionized water, and the deionized water is pure water after most of ion particles in the water are removed, and the distribution of the magnetic induction lines in the T-shaped groove can not be influenced at all.
Preferably, the bottom of the supporting block is also in an inverted T shape, a second limiting permanent magnet is arranged on the upward surface of the bottom of the supporting block, and an electromagnet facing the second limiting permanent magnet is arranged on the wall surface of the T-shaped groove.
In order to prevent the support component from moving up far or colliding with the track under the larger support force of the support electromagnet, the second limit permanent magnet and the electromagnet on the wall surface of the T-shaped groove opposite to the second limit permanent magnet are used for limiting the moving up distance of the support component.
Preferably, the front end face and the rear end face of the partition plate are provided with guide limiting magnets, the front end face and the rear end face of the bottom of the supporting block are provided with third limiting permanent magnets, and the third limiting permanent magnets face the guide limiting magnets. Spacing along track length direction between baffle and the supporting shoe is also accomplished through magnetic force to avoid surface contact, because the lift of friction scheduling problem influence supporting component, thereby influence the weighing precision of device.
Preferably, the cross section of the supporting block is in a composite I shape, the supporting block is provided with an upper horizontal plate and a lower horizontal plate and is connected by using two vertical rib plates, and the surfaces of the two vertical rib plates, which are deviated from each other, are close to the groove width surface of the opening of the T-shaped groove. The conventional I-shaped structure has poor left and right stability due to the fact that only one vertical rib plate is arranged, the cross section is easy to rotate, the double-rib-plate type composite I-shaped structure is enhanced in structural stability and small in self weight, and loss of original current I1 for maintaining suspension of the supporting assembly is low.
Preferably, the rolling support is a universal ball bearing or a rolling needle. The conveyer belt will rub when contacting with the upper surface of the supporting component, which affects the forward movement tendency of the conveyer belt, and the friction of the universal ball bearing or the roller pin is greatly reduced.
Further, weighing device still includes the camera, and the camera sets up in conveyer belt one side, and all supporting components have been embraced to camera monitoring range. The camera is used for identifying one article on the conveyer belt, matches the position signal of the article on the conveyer belt with the current signal of the supporting electromagnet corresponding to the supporting component at the corresponding position, the same article is weighed by the supporting components at different positions when being circulated to different positions, the matching and screening of the position signal are also needed, and the camera signal and the current signal of the supporting electromagnet at a plurality of positions are transmitted into the same controller for processing and conversion.
Compared with the prior art, the invention has the beneficial effects that: according to the invention, the weight of an article is reflected by the change of the exciting current of the magnetic suspension through the supporting mode of the magnetic suspension, and after the supporting force is increased, the supporting assembly can be approximately kept at the same height position, and the conveying belt cannot shake, vibrate or deform; the same article is subjected to weighing for multiple times in the measuring section, the weight data are mutually calibrated, if one article has larger deviation, the fault of the device can be timely known, and a manager is prompted to check and remove the article; the plurality of supporting assemblies support and cooperate with the supporting electromagnets below to transmit weight signals through signal wires, when an article is long, data of two or even three supporting assemblies can be combined to perform corresponding processing, and components in the measuring section are fully utilized; because the goods on the conveyer belt are upwards jacked up to keep the height position, the conveyer belt can not vibrate at the initial position and the final position, so that the goods can be continuously sent into the measuring section and sent out of the measuring section, a longer conveying distance is not required to be reserved for buffering the vibration caused by the height change when the goods enter the measuring section, the goods are continuously measured, and the space utilization rate is high.
