[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] On the disposable tableware production line, whether it is manual packaging or mechanical packaging, there is a certain amount of leakage, resulting in the tableware packages leaving the factory missing one, multiple or even all tableware. For this reason, please refer to Figure 1-Figure 13 The present invention provides an automated quality inspection device for tableware packaging, which can screen and remove tableware packages with missing tableware and empty packages to ensure the quality of tableware before leaving the factory.

[0045] The automatic quality inspection device for tableware packaging comprises two conveying units, and two quality inspection and screening units are arranged between the two conveying units.

[0046] See also Figure 2 The two transport units are conveyor line No. 1 1 and conveyor line No. 2 4. Conveyor line No. 1 and conveyor line No. 2 4 are preferably belt conveyors. Conveyor line No. 1 is used to convey the packaged tableware packages to be inspected along direction A, and conveyor line No. 2 4 is used to convey the tableware packages that have passed the inspection and screening along direction B.

[0047] See also Figure 2 and Figure 3 The two transport units are at a ninety-degree angle in the horizontal projection direction. Conveyor line No. 1 is higher than conveyor line No. 2 4, and the two have an overlapping part in the horizontal projection direction, that is, one end of conveyor line No. 1 extends to the top of conveyor line No. 2 4, so as to cooperate with the quality inspection and screening unit to form a complete conveying inspection chain and complete continuous quality inspection without stopping.

[0048] The two quality inspection and screening units are the empty package inspection mechanism 2 and the error inspection mechanism 3. The empty package inspection mechanism 2 is used to detect and screen out the empty packages on the No. 1 conveyor line 1. The error inspection mechanism 3 is used to detect the tableware packages with some tableware missing, and remove the unqualified products and transfer the qualified products to the No. 2 conveyor line 4.

[0049] Next, the empty packet detection mechanism 2 and the error detection mechanism 3 are described in conjunction with specific implementation methods.

[0050] Please continue reading Figure 2 and Figure 3 The empty package detection mechanism 2 includes a fixed frame 21 , one end of which is fixedly connected to the frame of the No. 1 conveyor line 1 , and one side of the fixed frame 21 is provided with an adsorption component 22 .

[0051] See also Figure 4-Figure 8 The adsorption assembly 22 includes a fixed sleeve 221, which is fixedly connected to the fixed frame 21 through a bracket. The fixed sleeve 221 is located directly above the No. 1 conveyor line 1. A rotating cylinder 222 is rotatably connected to the inner wall of the fixed sleeve 221. Both the fixed sleeve 221 and the rotating cylinder 222 are hollow structures. At least one through hole 2221 is opened on the surface of the rotating cylinder 222. The two ends of the through hole 2221 are respectively connected to the internal cavities of the fixed sleeve 221 and the rotating cylinder 222. When there are multiple through holes 2221, the multiple through holes 2221 are distributed in a circular array with the axis of the fixed sleeve 221 as the center, so that the air intake is more uniform. The surface of the rotating cylinder 222 protrudes outward along one diameter direction to form an adsorption nozzle 223 for adsorbing empty packages. The interior of the fixed sleeve 221 is connected to a vacuum generator 225 through an exhaust pipe 224 to provide a vacuum environment for the adsorption nozzle 223.

[0052] As an embodiment, a blanking plate 23 is fixedly connected to the fixing frame 21, and the fixing frame 21 is located outside the rotation range of the suction nozzle 223 and the empty bag to avoid motion interference with the suction nozzle 223 and the empty bag. The blanking plate 23 is provided with an angle at one end close to the suction component 22, and its vertical projection is a cone, and the distance between its top end line and the minimum distance of the rotation range of the suction nozzle 223 is between 0.1MM-1MM.

[0053] See also Fig. 9 The width of the suction nozzle 223 is smaller than the width of the tableware package. After adsorption, the two sides of the empty package will be exposed outside the suction nozzle 223. During the rotation of the suction nozzle 223, the exposed part of the empty package will be blocked by the unloading plate 23, that is, the top of the unloading plate 23 will enter between the empty package and the suction nozzle 223, so that the empty package cannot continue to rotate with the suction nozzle 223, and finally the empty package will separate from the suction nozzle 223.

[0054] As an embodiment, an empty bag box 24 is provided below the fixing frame 21 for collecting empty bags. The end of the unloading plate 23 away from the adsorption assembly 22 is tilted downward, so that the empty bags can automatically slide into the empty bag box 24 along the unloading plate 23 under the action of gravity.

[0055] As an embodiment, a motor 25 is fixedly mounted on the fixed frame 21, and the output end of the motor 25 is drivingly connected to one end of the rotating drum 222, so as to drive the rotating drum 222 and the suction nozzle 223 to rotate. Specifically, the output end of the motor 25 can be directly connected to one end of the rotating drum 222, or connected to the rotating drum 222 through a reduction structure to reduce the rotation speed of the rotating drum 222. The reduction assembly is preferably a large and small gear transmission pair or a belt transmission pair.

[0056] See also Figure 4 The error detection mechanism 3 includes a mounting seat 31, one end of which is fixedly connected to the frame of the second conveyor line 4. A spring-type quality inspection component 32 is arranged on the mounting seat 31, which is used to detect and screen the tableware packages whose quality is not enough to meet the standard value, so as to eliminate the tableware packages with missing tableware.

[0057] See also Figure 10-12The cam 324 is fixedly connected to the support frame 321 of the second embodiment of the present invention, and the cam 324 is fixedly connected to the support frame 321 of the second embodiment of the present invention.

[0058] As an embodiment, a thread is provided on the surface of one of the fixing rods 321, and two nuts 327 are connected to the thread. The two nuts 327 are respectively provided on both sides of the support plate 325, and are used to fix the support plate 325. By screwing the nuts 327, the height of the support plate 325 can be adjusted, and then the elastic force of the tension spring 326 can be adjusted to match the elastic force of the tension spring 326 with the weight of the cutlery package. The other fixing rod 321 is a bare rod, and there are two tension springs 326, so that the support plate 325 and the material dividing plate 324 are evenly stressed and can maintain a stable state.

[0059] A limiting assembly 33 is provided on the mounting seat 31 for limiting the rotation range of the dividing plate 324 .

[0060] See also Fig.11 and Fig.12 The limiting assembly 33 includes two symmetrically arranged fixing plates 331, the bottom ends of the two fixing plates 331 are fixedly connected to the mounting base 31, the opposite sides of the two fixing plates 331 are fixedly connected with a bottom baffle 332 and a top baffle 334, and both sides of the dividing plate 324 are fixedly connected with the limiting plates 333, and the limiting plates 333 can rotate between the bottom baffle 332 and the top baffle 334.

[0061] Continue to refer Fig.13 , the line connecting the center of the bottom end of the tension spring 326 and the rotation center of the dividing plate 324 is extended to form the C axis, and the line connecting the center of the top end of the tension spring 326 and the rotation center of the dividing plate 324 is extended to form the D axis. The bottom end of the tension spring 326 is located on the support plate 325, and its top end can rotate with the dividing plate 324. During the rotation, the angle between the C axis and the D axis will change. Under the restriction of the limit assembly 33, the C axis and the D axis will not overlap, and the angle is always an acute angle greater than zero degrees, so the tension spring 326 can be prevented from being stretched to the maximum state. After the cutlery bag is separated from the dividing plate 324, the dividing plate 324 can be smoothly reset under the tension.

[0062] As one embodiment, a shaking assembly 34 is provided between the dividing plate 324 and the rotating drum 222 , which can promote the dividing plate 324 to shake within a certain range, so that the underweight tableware packages can slide off the dividing plate 324 .

[0063] See also Fig.10 The shaking assembly 34 includes an extension plate 341 and a spiral plate 342, wherein the bottom end of the extension plate 341 is fixedly connected to the dividing plate 324, and the spiral plate 342 is fixedly connected to one end of the drum 222. The spiral plate 342 can intermittently contact the top of the extension plate 341 as the drum 222 rotates, and pushes the dividing plate 324 downward through the extension plate 341, so that the dividing plate 324 rotates counterclockwise by a certain angle. When the spiral plate 342 is separated from the extension plate 341, the dividing plate 324 will rebound under the action of the tension spring 326 and swing back and forth. It is worth noting that while the shaking assembly 34 drives the dividing plate 324 to swing, it does not change the upward tilted state of the end close to the No. 1 conveyor line 1, thereby ensuring the unloading effect of the tableware packages that do not meet the weight standard.

[0064] The working process of the automatic quality inspection device for tableware packaging of the embodiment of the present invention is as follows:

[0065] The tableware package to be inspected is transported along direction A through conveyor line 1 No. 1. The vacuum generator 225 evacuates the interior of the fixed sleeve 221 through the exhaust pipe 224. Since the fixed sleeve 221, the rotating drum 222, the suction nozzle 223 and the external environment are in a connected state, during the vacuuming process, the external air enters the interior of the device through the suction nozzle 223, and a pressure difference occurs at both ends of the suction nozzle 223. When an empty package appears on conveyor line 1 No. 1, due to its light weight, it can be adsorbed by the suction nozzle 223, so that the empty package is separated from the transportation team. The motor 25 drives the rotating drum 222 to rotate, thereby driving the suction nozzle 223 and the empty package at one end of the suction nozzle 223 to make a circular motion. When the rotating drum 222 rotates a certain angle, the top of the unloading plate 23 will enter between the empty package and the suction nozzle 223, so that the empty package cannot continue to rotate with the suction nozzle 223. Finally, the empty package will be separated from the suction nozzle 223, slide down along the inclined surface of the unloading plate 23, and automatically fall into the empty package box 24.

[0066] The remaining cutlery packages continue to move along the A direction with the No. 1 conveyor line 1. When the cutlery packages move to the end of the No. 1 conveyor line 1, they will leave the No. 1 conveyor line 1 and fall on the dividing plate 324. If a certain cutlery is missing from the cutlery package, the weight of the package is insufficient and it will slide directly down the surface of the dividing plate 324. If the cutlery package is of good quality, the dividing plate 324 will be driven by gravity to rotate counterclockwise by a certain angle. When the dividing plate 324 rotates to a state where the end close to the No. 1 conveyor line 1 is tilted downward, the cutlery package will slide down along the dividing plate 324, fall on the No. 2 conveyor line 4, and be transported to the next process along the No. 2 conveyor line 4.

[0067] Through the cooperation of two conveying units and two quality inspection and screening units, a complete conveying inspection chain can be formed to complete non-stop continuous quality inspection, thereby eliminating missing tableware packages or even empty packages on the production line and improving production quality.
