Technical Field

[0001] The invention relates to a poultry online weighing system and process. Background Art

[0002] At present, the various cutting machines of the poultry automatic cutting line cannot accurately cut all the products on the line. The products need to be classified by weight. A small amount of overweight and underweight products will be removed from the line. Products that meet the weight requirements will be divided into two categories: heavy and light. The two categories of products correspond to different cutting machines, so that the cutting is more accurate and the product output is higher. Therefore, a continuous online weighing device is needed, and the weighing speed and accuracy must meet the requirements of the matching cutting line.

[0058] First, the object to be weighed is hung on the hollow hook of the hook assembly; then, the hook assembly is transported forward; second, the connecting rod of the hook assembly is laterally positioned;

[0059] Before weighing, the hollow hook is lifted in the vertical direction with the help of an auxiliary tool that moves forward synchronously. The auxiliary tool rises for the first time along the set guide path, so that the hollow hook and the connecting rod are separated for the first time and move forward synchronously. Again, during weighing, the auxiliary tool walks on the weighing sensor and rises again, so that the hollow hook and the connecting rod continue to remain separated for weighing. The weighing sensor obtains the weight of the auxiliary tool, the hollow hook and the object to be weighed.

[0060] As a further improvement of the above technical solution:

[0061] Including the above-mentioned poultry online weighing system, the specific steps are as follows;

[0062] Step 1: The hook components are installed on the continuous conveying group at equal intervals, and the object to be weighed is hung on the hollow hook of the hook component and moved forward to the direction change station;

[0063] Step 2: At the direction-changing station, the hollow hook carries the object to be tested from the track opening to the guide track; at the same time, the connecting rod of the hook assembly enters the clamping arc channel from the clamping channel opening, and under the action of the clamping support guide wheel and the annular clamping strip, the arc-shaped bayonet block bites the connecting rod and drives it forward, and at the same time, the supporting pad bites the hollow hook;

[0064] Step 3: First, the central axis group drives the rotating bracket to rotate; then, the guide wheel A moves and rises at the curved guide line, so that the supporting pad tops the hollow hook and separates from the connecting rod; then, the guide wheel B moves and rises on the roller support block;

[0065] Step 4: When the guide wheel B reaches the weighing support section of the roller support block, the guide wheel B pushes the weighing trolley upward, and the guide wheel A is suspended on the curved guide line; weighing is performed through the weighing sensor.

[0066] The present invention uses a weighing trolley, which can run synchronously with the hook, and the roller on the back of the trolley can drive the trolley to rise and fall when running on the curved guide line track, that is, the trolley performs a compound movement of rotation and lifting. The supporting pad on the trolley can be inserted into the hook, and the supporting pad can rise with the rise of the guide wheel, so as to lift the hook and suspend it in the air, so that when the guide wheel passes the weighing sensor, the total weight of the material, the trolley weighing block and the hook can be weighed.

[0067] The structure of the weighing trolley of the present invention is that its driving wheel runs in a circular track, which can realize the circular and lifting compound motion of the trolley, and its guide wheel runs on the supporting block of the sensor assembly to realize the circular and lifting compound motion of the weighing block, and the weighing block is located on the rear side of the guide wheel A, and the operation is smooth; multiple groups of guide parts can guide the hook assembly to the optimal position and minimize the vibration of the material during operation, thereby ensuring the weighing accuracy.
