The turning bracket 21 is a # -shaped structure formed by splicing two oppositely arranged guard plates 211 and two oppositely arranged cantilevers 212 in a staggered mode. The two guard plates 211 are disposed on the upper surfaces of the cantilevers 212 for positioning the two outer sidewalls of the carrier 100, and the two cantilevers 212 are used for supporting the bottom of the carrier 100, so that the sides and the bottom of the carrier 100 can be well supported when being turned over, and the carrier is not easy to fall off.

As summarized above, the base frame 13 integrates all the mechanisms and components of the automatic roll-over unloader to form an integral mechanism module, so that the automatic roll-over unloader can be quickly moved and flexibly spliced in other mechanisms in the later period, and the full automation of the production line is realized.

Referring to fig. 1 to 3, the turnover driving mechanism 23 includes a turnover shaft 231, a turnover arm 232, an air cylinder connecting arm 233, and an air cylinder 234; the overturning shaft 231 is erected on the other side of the base frame 13 through a bearing with a base, one end of the overturning arm 232 is fixedly connected with the overturning shaft 231, and the other end of the overturning arm 232 is rotatably connected with the outer end of the air cylinder connecting arm 233; the cylinder connecting arm 233 is fixedly connected with the cylinder 234, and the cylinder 234 is a swing cylinder.

The flipping driving mechanism 23 swings the flipping arm 232 through the telescopic motion of the cylinder connecting arm 233 to drive the flipping shaft 231 to rotate. The cylinder 234 is mounted to the base frame 13 by a cylinder base mount. When the overturning device is in an overturning state, the air cylinder connecting arm 233 is in an extending state, and the connecting end of the overturning arm 232 and the air cylinder connecting arm 233 is far away from the air cylinder 234; in the turning state, the cylinder connecting arm 233 is in the retracted state, and the connecting end of the turning arm 232 and the cylinder connecting arm 233 is close to the cylinder 234.

As above, the turning driving mechanism 23 is linked by the components from the waiting turning state to the turning state, that is, when the cylinder 234 retracts the cylinder connecting arm 233, the turning arm 232 rotates clockwise to drive the turning shaft 231, so that the turning bracket 21 rotates clockwise to dump the goods; on the contrary, when the cylinder 234 extends out of the cylinder connecting arm 233, the turning arm 232 rotates counterclockwise to drive the turning shaft 231, so that the turning bracket 21 rotates counterclockwise back to the conveying flow channel. The mechanism for processing the product in the next step can be arranged on the other side of the turnover unloading machine, the unloaded product can be directly processed in the next step, and time and labor are saved.

In addition, the turning bracket 21 is respectively provided with clamping devices 22 at two sides close to the guard plate 211; the clamping device 22 comprises clamping jaws and a clamping cylinder 223 for driving the clamping jaws to open and close. The clamping jaw comprises an upper pressing plate 221 and a lower pressing plate 222 which are oppositely arranged, and mounting plates for fixedly mounting the upper pressing plate 221 and the clamping cylinder 223 are further arranged on two sides of the overturning bracket 21; the lower pressure plate 222 is fixedly connected with the outer end of the piston rod of the clamping cylinder 223. The fixed upper pressing plate 221 is used for transversely positioning the carrier 100, and when the clamping cylinder 223 is extended, the lower pressing plate 222 is driven to move upwards to be close to the upper pressing plate 221 so that the clamping jaws are in a clamping state to clamp the carrier 100; when the clamp cylinder 223 is unloaded, it drives the lower platen 222 to move downward away from the upper platen 221 to release the clamp jaws to release the carrier 100.

When the detection mechanism 4 detects that the carrier 100 with the product enters the conveying flow channel, the stop mechanism 3 mounted on the base frame 13 performs a stop action. The stop plate 31 between the two rollers 11 is pushed out by the second driving mechanism 23 and passes through the upper surface of the conveying flow channel, so as to stop the carrier 100 from advancing, and at this time, the carrier 100 is abutted to the stop plate 31. Guide push rods 34 for guiding are respectively arranged on two sides of the bottom surface of the stop plate 31, and the guide push rods 34 are installed on the mechanism base 13 through shaft sleeves. The guide push rod 34 can prevent the stopper plate 31 from being skewed when pushed out or retracted.

When the carrier 100 with the dumped products returns to the conveying flow channel again, the detecting mechanism 4 detects that the carrier 100 is empty, the stop plate 31 is retracted to be below the plane of the conveying flow channel, and the first driving mechanism 12 drives the conveying roller 11 to rotate to convey the carrier 100 out of the conveying flow channel.

Referring to fig. 4 and 5, the clamping device 22 is shown in an enlarged view in partial operation and in a non-operation state.

The work flow of the automatic overturning unloading machine provided by the invention is as follows:

the position of the turnover support 21 of each turnover mechanism 2 is called a station, the forward direction of the conveying flow channel is taken as a reference, the group of turnover mechanisms 2 at the forefront side is called a first station, and so on, the working flows of the first station and the second station are explained in the embodiment, and the working flows of the first station and the second station are repeated in the subsequent stations;

firstly, a first group of carriers 100 filled with products enter a conveying flow channel, when a detection mechanism 4 positioned at a first station detects that the first station has no carrier 100, a stop plate 31 positioned at the front side of the first station is driven by a second driving mechanism 23 to be pushed out of the upper surface of the conveying flow channel to stop the first group of carriers 100, so that the first group of carriers stop on an overturning bracket 21 at the first station; if the detection mechanism 4 detects that the carrier 100 is already present at the first station, the stop plate 31 located at the rear side of the first station is pushed out of the upper surface of the conveying runner, and the second group of carriers 100 is blocked from entering the first station. When the first set of carriers 100 stops at the first station, the first driving mechanism 12 stops working, that is, the roller 11 of the first station stops rotating; the first set of carriers 100 is in place. The mechanisms of the second station repeat the action of the first station to stop the second group carrier 100 to the second station.

Next, after the detection mechanisms 4 located at the first station and the second station detect that the carrier 100 is in place, the clamping cylinders 223 located at both sides of the turning bracket 21 drive the lower pressing plate 222 to move upward and abut against the bottom of the flange of the carrier 100 and the clamping jaws formed by the upper pressing plate 221 pressing the upper surface of the carrier laterally to clamp the carrier 100 located at the station.

Finally, the air cylinder 234 of the turnover mechanism 2 drives the air cylinder connecting arm 233 to retract, so that the turnover arm 232 swings clockwise, that is, the turnover shaft 231 rotates clockwise, and the turnover bracket 21 turns clockwise and upwards to be larger than 90 degrees to dump the product in the carrier 100 to other mechanisms beside; after the dumping is finished, the air cylinder connecting arm 233 pushes the overturning arm 232 to swing anticlockwise, and then the overturning shaft 231 rotates anticlockwise to drive the overturning bracket 21 to reset to the conveying flow channel; while the clamp cylinder 223 unloads the lower platen 222 to retract downward away from the flange bottom of the carrier 100, i.e., the jaws release the carrier 100. The detection mechanism 4 detects that the carriers 100 on the station are not loaded with products, the stop plate 31 retracts to the upper surface of the conveying flow channel, and the first driving mechanism 12 works, namely the conveying roller 11 rotates to convey the two groups of carriers 100 out of the turnover mechanism 2, so that the two groups of products are dumped.

Therefore, the conveying flow channel transportation carrier is adopted, and the products in the carrier are poured onto other equipment beside the turnover unloading machine through the cooperative operation of the turnover mechanism and the clamping device, so that the products can be directly processed in the next step, the manual participation is saved, the labor intensity is reduced, the efficiency is improved, and the cost is saved; the turnover mechanism and the clamping device have simple structures, are safe and reliable, and are convenient to use and maintain; and the turnover mechanism can select two or four groups of turnover mechanisms to operate simultaneously according to the capacity requirement, and has certain flexibility.
