As shown in fig. 1-4, embodiments of the present disclosure provide a conveyor apparatus including a plurality of conveyors 100 and weighing devices 200. A plurality of conveyors 100 are coupled back and forth for conveying material in a defined conveying direction. The weighing device 200 is disposed in the engagement space between two adjacent conveyors 100. The weighing apparatus 200 comprises a weighing platform 210 arranged in suspension, the top of the weighing platform 210 being flush with the conveying surface of the conveyor 100.

In the case where the plurality of conveyors 100 are in operation, the conveying directions of the plurality of conveyors 100 are the same so that the material is conveyed to the designated place along the defined conveying direction. In order to determine the weight of the material during the conveying process, a weighing device 200 is arranged in the joint space between two adjacent conveying devices 100, and the weighing device 200 comprises a weighing platform 210. In the actual production process, it is relatively common to set up the supporting structure in the bottom of weighing platform 210, like this, because the existence of bottom fixed fulcrum, the moment of the material friction on weighing platform 210 for the fulcrum of supporting structure will give weighing device 200 additional power to cause the error of weighing, consequently, hang the setting with weighing platform 210 in this application embodiment to this reduces weighing error, improves the measuring accuracy. Alternatively, the weighing device 200 may be a belt scale.

With the conveying equipment provided by the embodiment of the disclosure, materials can be moved from one conveying device to the suspended weighing device by means of the movement of the conveying device, so that the weight of the materials can be determined, and the materials which are weighed can be moved to the next conveying device continuously by means of the movement of the next material. Through the suspended weighing device, the influence of the results of the symmetrical quantity such as the friction force generated between the material and the weighing platform can be reduced, the measurement error is reduced, and the weighing accuracy is improved.

In some embodiments, the weigh platform 210 includes a top plate 211, a bottom plate 212, a plurality of load cells 213, and a processing module. A weighing space is formed between the top plate 211 and the bottom plate 212, and an upper surface of the bottom plate 212 is configured as a floor of the weighing table 210. The weighing space communicates with the adjacent conveyor 100 to smoothly move the material to the top of the weighing platform 210. The plurality of load cells 213 are disposed between the top plate 211 and the bottom plate 212 and are equally spaced apart along the circumference of the top plate 211 or the bottom plate 212, so that each load cell 213 receives the same internal force during the weighing process. The weighing sensor 213 comprises a force action end and a fixed end, wherein the force action end is connected with the top plate 211, and the fixed end is connected with the bottom plate 212; alternatively, the force application end is connected to the bottom plate 212 and the fixed end is connected to the top plate 211. Thus, after the material moves to the top of the weighing platform 210, the force application end receives the force applied by the top of the weighing platform 210. And the processing module is electrically connected with the plurality of weighing sensors 213 and is used for obtaining the force values of the plurality of weighing sensors 213 and metering the weight of the material. The load cell 213 is operated when the material has just started to move into contact with the top of the weighing platform 210, so that the force detected by the load cell 213 may be constantly changing in value if the material has not completely moved onto the top of the weighing platform 210, and the processing module is therefore also configured to record the weight of a plurality of metered materials until the metered materials no longer change within a predetermined period of time, and the weight of the material no longer changes is output. Alternatively, the preset time period may be set to 5s, 10s, or 20 s. Optionally, the setting position of the processing module is not specifically required in the embodiments of the present disclosure.

In some embodiments, the weigh platform 210 also includes a plurality of connecting rods 214. A plurality of connecting rods 214 are used to connect the top plate 211 and the bottom plate 212. Wherein the load cell 213 is located between the top plate 211 and the connecting rod 214, or between the bottom plate 212 and the connecting rod 214. Alternatively, a plurality of connecting rods 214 connect the top plate 211 and the bottom plate 212 to achieve a weighing space between the top plate 211 and the bottom plate 212 and to improve the stability of the weighing platform 210.

In some embodiments, the weighing apparatus 200 further includes a support portion 220 and a hanger portion 230. The supporting portion 220 is located in the connecting space between two adjacent conveying devices 100, and has a receiving space for receiving the weighing platform 210. And a hanging part 230 provided on the top of the support part 220 for hanging the weighing platform 210.

In the embodiment of the present disclosure, in order to improve the working stability of the suspended weighing platform 210, the supporting portion of the weighing device 200 is located in the connection interval between two adjacent conveying devices 100, so that the weighing platform 210 is disposed in the accommodating space of the supporting portion and is communicated with two adjacent conveying devices 100. Optionally, the distance between the end of the top of the weighing platform 210 adjacent to the conveyor and the conveyor 100 is set between 10mm and 50mm, so as to ensure that the material conveyed by the conveyor 100 moves smoothly onto the top of the weighing platform 210, prevent the weighing platform 210 from influencing the movement of the conveyor 100 due to too close distance, and prevent the material from falling off due to too far distance.

Optionally, the top of the weighing platform 210 is connected to the hanging part 230, that is, one end of the hanging part 230 is connected to the top plate 211, and the other end is connected to the top of the supporting part 220, so as to suspend the weighing platform 210 and improve the weighing accuracy of the weighing platform 210.

In some embodiments, support 220 includes a first upright 221, a cross-beam 222, and a second upright 223. The first and

second columns

221 and 223 are vertically disposed at both sides of the conveyor 100, respectively. Alternatively, in the embodiment of the present disclosure, the distance between the first upright 221 and the second upright 223 is at least not less than the width of the conveyor, and the width of the table top of the weighing platform 210 is kept as consistent as possible with the width of the conveyor, so that in the case of conveying materials with large size, there is no fear that the materials get stuck. The cross member 222 is fixedly connected to the top ends of the first and

second columns

221 and 223, and the hanging portion 230 is provided on the cross member 222. Optionally, the cross beam 222 is bolted or welded to the first and

second columns

221, 223. Alternatively, the cross beam 222 is a round bar, is perpendicularly connected to both the first upright 221 and the second upright 223, and is parallel to the conveying surface of the conveyor 100.

In some embodiments, the hanger 230 includes a hanging loop 231, a hanger bar 232, and a hook 233. The hanging ring 231 is sleeved on the beam 222. The hook 233 is fixedly connected to the suspension loop 231 via a suspension rod 232, and the weighing platform 210 can be suspended by a lifting lug 2111 provided on the top plate 211 and engaged with the hook 233.

In the embodiment of the present disclosure, in order to improve the safety and the service life of the weighing apparatus 200, the hanging ring 231 of the hanging portion 230 is sleeved on the cross beam 222. Since the weighing devices 200 are disposed in the engagement space between two adjacent conveyors 100, when the material is moved from the conveyor 100 to the weighing platform 210 or when the material is moved from the weighing platform 210 to the conveyor 100 by other materials, the weighing platform 210 moves in the engagement space, and if the hanging part 230 is fixedly connected to the cross beam 222, the hanging part 230 is likely to be broken under a long-term action, and workers or users working around the hanging part may be accidentally injured. The suspension ring 231 is sleeved on the cross beam 222, so that the force between the suspension part 230 and the cross beam 222 is used as static friction force under the condition that the weighing platform 210 shakes, and the safety and the service life of the weighing device 200 are improved.

Optionally, in order to achieve the replacement of the weighing platform 210, a lifting lug 2111 is provided on the top plate 211 of the weighing platform 210, and the hanging hook 233 may achieve the suspension of the weighing platform by hooking the lifting lug. Optionally, a lifting lug 2111 is provided at the geometric center of the top plate 211 to improve the stability of the suspension of the weigh platform 210 and the uniformity of the force.

In some embodiments, a limiting groove 2221 is formed at a middle position of the cross beam 222, and the hanging ring 231 can be clamped in the limiting groove 2221 to prevent the hanging portion 230 from moving toward the first vertical column 221 or the second vertical column 223. The middle position of the cross beam 222 refers to a position that is equidistant from the first upright 221 and the second upright 223. In order to prevent the weighing platform 210 from shaking towards the first upright 221 or the second upright 223 under the condition of uneven stress, the suspension loop 231 drives the suspension portion 230 and the weighing platform 210 to move integrally, and the suspension loop 231 is clamped in the position of the limit groove 2221 in the middle of the cross beam 222, so that the stability of the weighing process and the weighing accuracy are further improved.

In some embodiments, the delivery apparatus further comprises a display device 300. The display device 300 is electrically connected to the processing module, and disposed on the first vertical column 221 or the second vertical column 223, and is configured to display the weight of the metered material. In this way, the user can conveniently check the weight of the material.

In some embodiments, support portion 220 further includes a cross foot 224 fixedly attached to the bottom of first upright 221 and the bottom of second upright 223. Thus, the base area of the supporting portion 220 and the bottom surface can be increased to improve stability.

In some embodiments, the support portion further includes a limit plate 225. The stopper plate 225 is disposed on a side of the first and

second columns

221 and 223 facing the weighing platform 210 in the conveying direction of the conveyor 100, between the cross beam 222 and the floor of the weighing platform 210. Thus, the movement range of the weighing platform 210 can be prevented from exceeding the connection interval between two adjacent conveying devices 100, the weighing platform 210 can be prevented from moving out of the accommodating space of the supporting part 220 towards the first upright column 221 and the second upright column 223, and the falling of materials can be prevented.
