Description

Technical Field

[0001] The present application relates to the technical field of cigarette production, and more specifically, to a rejection device of a packing system. Background Art

[0002] For the "Industry Cigarette QR Code Box Condition Association Management Subsystem", the system uses QR codes and No. 1 engineering codes to associate small boxes, cigarette strips, and cigarette boxes, requiring that the associated information is correct after the finished products are shipped out, and no missing information can exist.

[0003] In the packing system, due to uneven packaging of cigarette strips, abnormal rejection by the packing machine, irregular manual removal of cigarette strips, etc., the barcode scanning camera of the cigarette strips may not be able to recognize them. After the condition-item association with the No. 1 engineering code is performed, the system will only issue an audible and visual alarm to remind the packing machine that the "box condition association system association" has failed, and will not shut down or reject the cigarette box with the condition-item association failure. If the operator cannot accurately and efficiently locate the cigarette box according to the No. 1 engineering code and intercept and dispose of it, the cigarette box may flow into the finished product warehouse and require finished product traceability, otherwise it will cause quality accidents once it leaves the warehouse.

[0019] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0020] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0021] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0022] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0023] The present application provides a rejection device and method for a packing system, which automatically identifies and rejects cigarette pieces that fail condition-piece association through intelligent means, avoiding them from flowing into the finished product warehouse, reducing quality risks and labor costs.

[0024] like Figure 1 As shown, the rejection device 200 of the packing system provided in the present application includes an industrial computer and an output belt 210 connected to the main conveyor belt 170 of the packing system 100, and the other end of the output belt 210 extends to the high-bay warehouse system 300, from the main conveyor belt 170 to the high-bay warehouse system 300, and a barcode scanning camera 230 and a rejection component are sequentially arranged on the output belt 210.

[0025] The barcode scanning camera 230 is fixed to the top of the output belt 210 through the fixing frame 220, and is used to scan the No. 1 engineering code of the cigarette box passing below it. The rejection assembly includes a rejection push rod 280, a rejection belt 290 and a temporary storage cabinet 2100. The rejection push rod 280 and the rejection belt 290 are respectively arranged at relative positions on both sides of the output belt 210, and the temporary storage cabinet 2100 is arranged at the end of the rejection belt 290.

[0026] The industrial computer is respectively connected to the code scanning camera 230 and the actuator signal of the rejection push rod 280.

[0027] Preferably, if Figure 1 As shown, the output belt 210 is also provided with a first proximity switch 260 corresponding to the code scanning camera 230, and the first proximity switch 260 is connected to the industrial computer signal, and the industrial computer is connected to the actuator signal of the code scanning camera 230. When the first proximity switch 260 detects the cigarette box 400, it means that the cigarette box is located directly below the code scanning camera 230. After receiving the arrival signal of the first proximity switch 260, the industrial computer controls the code scanning camera 230 to scan the No. 1 engineering code of the cigarette box below.

[0028] Preferably, if Figure 1 As shown, a box condition association management system query component is also provided above the output belt 210 between the barcode scanning camera 230 and the rejection belt 290, and the box condition association management system query component is connected to the industrial computer signal.

[0029] As an embodiment, the query component of the box condition association management system includes a PDA handheld terminal 240 fixed directly above the output belt 210 by a fixing frame, the scanning port of the PDA handheld terminal 240 faces the output belt 210 below, and the display screen of the PDA handheld terminal 240 is perpendicular to the output belt 210. The query component of the box condition association management system also includes a color mark sensor 250, whose detection port faces the display screen of the PDA handheld terminal 240. The PDA handheld terminal 240 communicates with the box condition association management system. When the cigarette box is located directly below the PDA handheld terminal, the PDA handheld terminal 240 scans the No. 1 engineering code on the cigarette box, and sends the No. 1 engineering code to the box condition association management system for query to determine whether the No. 1 engineering code has an association relationship with 50 cigarette strips (500 cigarette boxes). If so, the query result displayed on the display screen of the PDA handheld terminal 240 is green; otherwise, the query result displayed on the display screen of the PDA handheld terminal 240 is red. The color mark sensor 250 is used to identify the color of the query result displayed on the display screen of the PDA handheld terminal 240 and transmit it to the industrial computer.

[0030] Preferably, if Figure 1 As shown, the output belt is also provided with a second proximity switch 270 corresponding to the query component of the box condition association management system. When the second proximity switch 270 detects the cigarette box 400, it means that the cigarette box is located directly below the PDA handheld terminal 240. After receiving the arrival signal of the second proximity switch 270, the industrial computer controls the PDA handheld terminal 240 to scan the No. 1 engineering code of the cigarette box below.

[0031] like Figure 1 As shown, the box packing system includes a main conveyor belt 170, a plurality of box packing machines and their supporting conveyor belts. Figure 1 The embodiment shown includes five packing machines numbered 110, 130, 140, 150, and 160. Each packing machine is equipped with a set of conveyor belts, each conveyor belt is provided with a coding machine 120, and each packing machine is provided with a bar-piece association end-side server. After each packing machine packs 50 cigarette bars into a piece cigarette box, the piece cigarette box is conveyed to the coding machine 120 for coding of the No. 1 engineering code, and then transported to the main conveyor belt 170 and output from the packing system. The cartoning machine transmits the QR code information of 50 cigarette strips to the condition-item association end-side server, and the coding machine transmits the corresponding No. 1 engineering code to the condition-item association end-side server, thereby realizing the condition-item association. Each condition-item association end-side server and coding machine puts the condition-item association information and No. 1 engineering code information into their respective condition association system databases. The condition association system database sends the condition-item association information to the box condition association management system. The box condition association management system combines the obtained cigarette strip-cigarette box association information with the condition-item association information to form box-condition-item association information.

[0032] The packing system also includes a switch and a general input-output module (GPIO module). The industrial computer is connected to the switch and the general input-output module respectively. The general input-output module is connected to the condition-related end-side server of each packing machine, and the switch is connected to the coding machine of each packing machine. The switch is equipped with a condition-related system database. Figure 2 The embodiment shown includes two interconnected switches, the original switch is connected to four of the coding machines by signal, forming a tree network, the fifth coding machine is connected to the newly added switch, and the industrial computer is connected to the newly added switch. Thus, the industrial computer can obtain the information of the No. 1 engineering code that failed to be associated on all coding machines from the switch. It can be understood that only one switch can also be used.

[0033] Specifically, the condition-item association information includes condition-item association success information and condition-item association failure information. Figure 2 As shown, if a condition-part association failure occurs in a packing machine, its condition-part association end-side server sends an end-side association failure alarm signal to GPIO. At this time, different packing machines drive the corresponding photocouplers (different packing machines have different colors of photocouplers), and convert the 24V end-side association failure alarm signal into a 3.3V input to different pins of the GPIO module. The signal of the GPIO module is read by the industrial computer through USB, thereby obtaining the corresponding packing machine association failure signal.

[0034] Based on the above, the present application also provides a rejection method for a packing system of an industrial computer. It should be noted that the rejection logic used by the industrial computer includes data reception, comparison, simple combination of information to generate a control signal and output of the control signal, which is a common setting of existing industrial computers.

[0035] As an embodiment, the elimination method includes:

[0036] P1: The industrial computer receives the No. 1 engineering code of the cigarette box where the condition-item association fails.

[0037] Specifically, the industrial computer cyclically accesses the condition association system database of each packing machine at preset intervals (for example, 3 seconds) to search for the most recent alarm code of the corresponding packing machine. If the alarm code is a condition-part association failure code, the industrial computer accesses the latest No. 1 engineering code in the corresponding condition association system database as the No. 1 engineering code of the cigarette box with the above-mentioned condition-part association failure.

[0038] P2: The industrial computer receives the recognition result of the No. 1 engineering code of the current cigarette box by the barcode scanning camera.

[0039] When a cigarette box appears directly below the barcode scanning camera, the barcode scanning camera scans the No. 1 engineering code on the cigarette box and transmits the recognition result to the industrial computer, so that the industrial computer compares the recognition result of the barcode scanning camera with the No. 1 engineering code of the cigarette box where the condition-item association fails.

[0040] Preferably, the barcode scanning camera identifies the No. 1 engineering code of the current cigarette box in response to the in-place signal of the first proximity switch.

[0041] P3: If the No. 1 engineering code is consistent with the recognition result, it means that the piece cigarette box directly below the current barcode scanning camera is the piece cigarette box that fails the above condition-piece association. Then the industrial computer controls the rejection push rod to push the current piece cigarette box into the rejection belt when it arrives.

[0042] During the production process, there are problems such as missing cigarette boxes or packs, blockage of the packing machine, blockage of the main conveyor belt, and manual replacement of cigarette boxes in the packing machine, which lead to incorrect association information on the server side of the item-item association, or errors in the query results of the PDA handheld terminal due to database update delays, access lags, etc., resulting in the inability to accurately determine the quality of the products entering the high-bay warehouse. Based on this consideration, it is preferred that Figure 3 As shown, the elimination methods include:

[0043] S310: The industrial computer receives the No. 1 engineering code of the cigarette box with the condition-item association failure transmitted by the industrial computer.

[0044] S320: The industrial computer receives the recognition result of the No. 1 engineering code of the current cigarette box by the barcode scanning camera.

[0045] S330: The industrial computer receives the query result of the box condition association management system query component on the current cigarette box, and the query result indicates that the box condition association of the current cigarette box is successful or unsuccessful.

[0046] When the cigarette box moves to the bottom of the PDA handheld terminal, the PDA handheld terminal scans the No. 1 engineering code on the cigarette box, queries the box condition association management system, obtains the query result, identifies the color of the query result through the color mark sensor, and sends the identified color information to the industrial computer. The industrial computer determines whether the query result is a successful box condition association or a failed box condition association based on the color information.

[0047] Preferably, the box condition association management system query component queries the current cigarette box in response to the arrival signal of the second proximity switch.

[0048] S340: The industrial computer determines whether the No. 1 engineering code is consistent with the recognition result and / or the query result is a failed association. If so, it means that there may be a problem with the association of the cigarette box, and S350 is executed; otherwise, the No. 1 engineering code is inconsistent with the recognition result (indicating that the condition-item association is successful), and the query result is a successful association, indicating that there is no problem with the association of the cigarette box, and S360 is executed.

[0049] S350: The industrial computer controls the rejection push rod to push the current cigarette box into the rejection belt when it arrives and enters the temporary storage cabinet.

[0050] Preferably, after the cigarette boxes are sent to the temporary storage cabinet, further correlation verification is performed on the cigarette boxes in the temporary storage cabinet.

[0051] Specifically, if the No. 1 engineering code is consistent with the recognition result, and the query result is a successful association, that is, the industrial computer recognizes that the condition-item association fails, but the PDA handheld terminal queries that the association is successful, it may be because the database update of the box condition association management system is delayed or the PDA access database is delayed. Then, after a preset time (for example, 15 minutes), the No. 1 engineering code of the current cigarette box is manually re-identified using the box condition association management system query component. If the query result is a successful association, the current cigarette box is transported to the high-bay warehouse system, otherwise, the cigarette box is manually opened to verify whether it has defects.

[0052] If the No. 1 engineering code is consistent with the recognition result, and the query result is an association failure (i.e., the industrial computer recognizes that the condition-item association fails, and the PDA handheld terminal queries that the association fails), or the No. 1 engineering code is inconsistent with the recognition result, and the query result is an association failure (i.e., the industrial computer recognizes that the condition-item association is successful, but the PDA handheld terminal queries that the association fails. It may be that the PDA detects that there are missing strips or packages in the cigarette box, or the condition-item association is misaligned due to blockage of the case packing machine, blockage of the main conveyor belt, manual replacement of cigarette strips in the case packing machine, etc., or the case packing machine does not recognize the association error, but the PDA recognizes that the data association logic is misaligned, such as one engineering code is associated with more than 50 pieces of data), then the current cigarette box will be discarded, and manual unpacking will be performed to verify whether the current cigarette box has defects.

[0053] S360: The industrial computer controls the rejection push rod to not move, and the current cigarette box directly enters the high-bay warehouse system.

[0054] This application fully considers various association failure situations, and minimizes the number of cigarette boxes with condition-item association failures entering the high-bay warehouse system, making it easier for quality management personnel to deal with them in a timely manner and reducing the cost of manual quality tracing.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application.
