Technical Field

[0001] This utility model relates to the field of toilet processing technology, and in particular to a toilet forming workstation. Background Technology

[0002] Toilets consist of a seat, inner tank, and outer casing. During the production process, the seat, inner tank, and outer casing are produced independently on different production lines. They are then transported together manually or by other means for bonding, wet repair, etc. The transportation distance is long, and the labor intensity of the operators is high.

[0003] Therefore, a toilet blank injection robot workstation is proposed in the related technology, which includes two sets of blank forming units arranged symmetrically in a C-shape. Each forming unit includes an inner liner forming machine, an outer liner forming machine, and a seat ring forming machine. Among them, a multi-joint robot is set between multiple vertical injection forming machines. The multi-joint robot can lift the contouring tray and use the contouring tray to transfer the seat ring, inner liner, and outer liner to the blank trimming table for manual blank trimming and other operations.

[0004] The aforementioned handling robot can only handle one blank at a time, resulting in low toilet production efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a toilet forming workstation to solve the problem of low toilet production efficiency caused by low efficiency in handling blanks.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A toilet forming workstation includes an upper buffer rack, a wet repair workbench, a transport robot, and a seat ring forming device, an inner liner forming device, an outer liner forming device, and the wet repair workbench arranged around the transport robot. The transport robot includes a robot body and a fork arm, the fork arm being located at the end of the wrist joint of the robot body, and the fork arm having at least two transport stations. The seat ring forming device has at least two seat ring forming stations; the inner liner forming device has at least two inner liner forming stations; the outer liner forming device has at least two outer liner forming stations; the upper buffer rack is used to store the blanks; and the wet repair workbench is located below the upper buffer rack.

[0008] In one embodiment, the fork arm is provided with positioning holes or positioning pins for positioning the bracket supporting the blank.

[0009] In one embodiment, the fork arm is rotatably mounted at the end of the wrist joint of the robot body.

[0010] In one embodiment, the seat ring forming device is a single-mold dual-tire seat ring forming machine, and / or the outer casing forming device is a single-mold dual-tire outer casing forming machine.

[0011] In one embodiment, the toilet forming workstation further includes a lower buffer shelf, and the transport robot is suspended and inverted above the lower buffer shelf.

[0012] In one embodiment, the toilet forming workstation further includes a blank turning machine and a conveyor line. The wet repair workbench is divided into a first wet repair workbench and a second wet repair workbench. The second wet repair workbench is located on the side of the first wet repair workbench away from the transport robot. An operating space for operators is formed between the first wet repair workbench and the second wet repair workbench. The conveyor line is located between the first wet repair workbench and the second wet repair workbench for transferring toilet blanks to the second wet repair workbench. The blank turning machine is straddling the conveyor line.

[0013] In one embodiment, there are two first wet repair workbenches, and the two first wet repair workbenches and the second wet repair workbench are arranged in a triangular pattern.

[0014] In one embodiment, the toilet forming workstation further includes a loading machine for transferring supply trays onto the conveyor line.

[0015] In one embodiment, the toilet molding workstation further includes a coating machine, which is located below the upper buffer rack.

[0016] In one embodiment, the toilet forming workstation further includes a connecting device for receiving the toilet blank on the second wet repair workbench.

[0017] The beneficial effects of this utility model are as follows: The seat ring forming device, inner liner forming device, and outer sleeve forming device in the above-mentioned toilet forming workstation each have at least two workstations, enabling the simultaneous formation of multiple blanks. The transport robot has at least two transport workstations, allowing it to transport multiple blanks simultaneously. The transport robot has high utilization, greatly improving the transfer efficiency of the blanks, shortening the toilet production cycle, and increasing production efficiency. It is worth noting that because the seat ring forming device, inner liner forming device, outer sleeve forming device, and wet repair workbench are arranged around the transport robot, compared to an assembly line setup, the required travel distance of the transport robot is shorter, further improving the transfer efficiency of the blanks, thereby further shortening the toilet production cycle. Moreover, the layout is compact, and the overall footprint is small. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

[0026] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0029] refer to Figures 1-5 As shown in the figure, this utility model embodiment proposes a toilet molding workstation, including a seat ring molding device 2, an inner liner molding device 3, an outer liner molding device 4, an upper buffer rack 6, a wet repair workbench 11, and a transport robot 1. The seat ring molding device 2 has two seat ring molding stations, the outer liner molding device 4 has two outer liner molding stations, and the inner liner molding device 3 has two inner liner molding stations. Specifically, the seat ring molding device 2 can be either two single-mold single-tire seat ring molding machines sharing the same support frame, or a single-mold double-tire seat ring molding machine. The outer liner molding device 4 can be either two single-mold single-tire outer liner molding machines sharing the same support frame, or a single-mold double-tire outer liner molding machine. A single-mold double-tire machine refers to a single-mold double-cavity mold capable of simultaneously forming two blanks, including but not limited to a seat ring blank, an inner liner blank, and an outer liner blank. The inner liner molding device 3 includes two single-mold single-tire inner liner molding machines. Both single-mold single-tire and single-mold double-tire structures are existing technologies and will not be described further here. Obviously, compared to single-mold single-tire seat ring forming machines and outer sleeve forming machines, single-mold double-tire seat ring forming machines and outer sleeve forming machines occupy less space. The seat ring forming device 2, inner sleeve forming device 3, outer sleeve forming device 4, and wet repair workbench 11 are arranged around the transport robot 1. For example, the wet repair workbench 11 and inner sleeve forming device 3 are respectively located on the front and rear sides of the transport robot 1, while the seat ring forming device 2 and outer sleeve forming device 4 are respectively located on the left and right sides of the transport robot 1. The upper buffer rack 6 is located above the wet repair workbench 11 for storing blanks. The transport robot 1 includes a robot body 101 and a fork arm 102. The robot body 101 is not limited to a six-axis robot. The fork arm 102 is located at the end of the wrist joint of the robot body 101 and has at least two transport stations, capable of simultaneously transporting at least two blanks. It is understandable that when there are more than two transport stations based on the fork arm 102, the seat ring forming device 2 can also be set with multiple seat ring forming stations, the outer sleeve forming device 4 can be set with multiple outer sleeve forming stations, and the inner liner forming device 3 can be set with multiple inner liner forming stations.

[0030] The toilet forming workstation described above features seat ring forming device 2, inner liner forming device 3, and outer sleeve forming device 4, each with at least two workstations, capable of forming multiple blanks simultaneously. The transport robot 1, with at least two transport workstations, can simultaneously transport multiple blanks. The transport robot 1 boasts high utilization, significantly improving blank transfer efficiency, shortening the toilet production cycle, and increasing production efficiency. It is worth noting that because the seat ring forming device 2, inner liner forming device 3, outer sleeve forming device 4, and wet repair workbench 11 are arranged around the transport robot 1, compared to an assembly line setup, the required travel distance of the transport robot 1 is shorter, further improving blank transfer efficiency and thus further shortening the toilet production cycle. Moreover, the layout is compact, resulting in a small overall footprint.

[0031] Understandably, due to the softness of the billet, the handling robot 1 uses a bracket to support the billet during transport. This bracket can be placed on the upper buffer rack 6. The handling robot 1 first removes the bracket from the upper buffer rack 6 and then transfers it to the seat ring forming device 2, inner liner forming device 3, or outer sleeve forming device 4, thus transferring the billet onto the bracket. To improve the stability between the billet and the bracket, a contoured bracket adapted to the surface shape of the billet is used. Furthermore, the bracket is absorbent; when a bracket becomes saturated with water, it needs to be placed on the buffer rack to allow the water to evaporate before continued use.

[0032] Based on this, to prevent the bracket from shifting relative to the handling robot 1, multiple positioning pins are provided on one of the fork arm 102 and the bracket, and multiple positioning holes are provided on the other. The positioning pins can be inserted into the positioning holes to position the fork arm 102 and the bracket, thereby achieving stable connection and handling. Specifically, the fork arm 102 is rotatably mounted at the end of the wrist joint of the robot body 101, and the position switching between the two handling stations is achieved by rotating the fork arm 102.

[0033] To provide more storage space for toilet blanks while making efficient use of space, the toilet forming workstation also includes a lower buffer rack 5 for storing the blanks, with the transport robot 1 suspended and inverted above the lower buffer rack 5. Therefore, the lower buffer rack 5 does not add extra space, resulting in a compact structure for the entire toilet forming workstation. The lower buffer rack 5 serves the same function as the upper buffer rack 6, both used to buffer and hold toilet blanks.

[0034] The toilet forming workstation also includes a blank-turning machine 9, used to rotate the toilet blank, which is formed by assembling the seat ring, inner liner, and outer sleeve, 180 degrees to perform comprehensive, multi-angle finishing of the toilet blank. (Reference) Figure 2As shown, the wet repair workbench 11 is divided into a first wet repair workbench 11a and a second wet repair workbench 11b. The toilet forming workstation also includes a conveyor line 8. The second wet repair workbench 11b is located on the side of the first wet repair workbench 11a away from the transport robot 1. An operating space for operators is formed between the first wet repair workbench 11a and the second wet repair workbench 11b. The conveyor line 8 is located between the first wet repair workbench 11a and the second wet repair workbench 11b and is used to transfer the toilet blank to the location of the second wet repair workbench 11b. The turning machine 9 is straddling the conveyor line 8. When the toilet blank is moved to the turning machine 9, the turning machine 9 flips the toilet blank 180 degrees.

[0035] After the operator performs wet finishing on the toilet blank at the first wet finishing workbench 11a, the transport robot 1 places the toilet blank on the upper buffer rack 6 or the lower buffer rack 5 and lets it stand for a period of time to allow the surface to dry. Then, the transport robot 1 places the tray supporting the toilet blank on the conveyor line 8, and then transfers the toilet blank to the second wet finishing workbench 11b via the conveyor line 8. The operator can then turn around and perform wet finishing on the toilet blank on the second wet finishing workbench 11b. That is, the entire toilet forming workstation only requires one person to operate. For example, the conveyor line 8 is set in a U-shape, which is composed of multiple conveyor rollers.

[0036] Furthermore, the toilet forming workstation also includes a plate-mounting machine 10, which is used to supply a bracket to the conveyor line 8. When the billet turning machine 9 turns the toilet blank, it transfers the toilet blank from the original bracket to a new bracket. Obviously, the shapes of the upper and lower end faces of the toilet blank are different, and the shape of the upper surface of the plate used before and after turning is also different.

[0037] Optionally, two first wet repair workbenches 11a are provided, one for placing two blanks synchronously transported by the transport robot 1, and the other for vacating the transport robot 1, facilitating the transfer of other blanks by the transport robot 1. Specifically, the two first wet repair workbenches 11a and the second wet repair workbench 11b are arranged in a triangular pattern, so that the distance between the operator and the three wet repair workbenches 11 is similar, which can effectively reduce the travel distance of the operator between different wet repair workbenches 11, thereby effectively reducing the labor intensity of the operator and improving production efficiency.

[0038] To facilitate the timely transfer of toilet blanks after wet finishing, the toilet forming workstation also includes a connecting device 12. The connecting device 12 is not limited to an AGV (Automated Guided Vehicle). It is used to receive the toilet blanks on the second wet finishing workbench 11b and transfer them to the next process. In this embodiment, the moving direction of the connecting device 12 is perpendicular to the moving direction of the conveyor line 8 when transferring the toilet blank to the second wet finishing workbench 11b. To transfer the toilet blank to the connecting device 12 or from the conveyor line 8 to the second wet finishing workbench 11b, the second wet finishing workbench 11b has lifting, rotating, and conveying functions.

[0039] In addition, the toilet forming workstation also includes a slurry coating machine 7, which is used to coat the blank with slurry. The slurry coating machine 7 is also located below the upper buffer rack 6 to make efficient use of space.

[0040] The toilet molding workstation also includes an electrical control cabinet, which is electrically connected to the aforementioned functional mechanisms (including but not limited to the handling robot 1, seat ring molding device 2, inner liner molding device 3, outer sleeve molding device 4, coating machine 7, etc.). Additionally, the toilet molding workstation includes a hydraulic station 14, used to provide power to the hydraulic actuators used in the aforementioned functional mechanisms.

[0041] Taking the seat ring forming time as less than the inner liner forming time and the outer sleeve forming time as an example (if the forming times of each component differ too much, the starting order of forming can be adjusted appropriately), the process of toilet production at the toilet forming workstation is explained. The seat rings formed simultaneously by seat ring forming device 2 are defined as seat ring blank #1 and seat ring blank #2, the inner liner formed simultaneously by inner liner forming device 3 are defined as inner liner blank #1 and inner liner blank #2, and the outer sleeve formed simultaneously by outer sleeve forming device 4 are defined as outer sleeve blank #1 and outer sleeve blank #2.

[0042] S1, seat ring forming device 2, inner liner forming device 3, and outer sleeve forming device 4 begin simultaneous grouting. After the seat ring grouting and forming is completed, the transport robot 1 receives a demolding command and proceeds to the seat ring forming device 2 to receive the #1 seat ring blank. After the #1 seat ring blank is received, another transport station on the fork arm 102 rotates to the seat ring forming device 2 and, driven by the transport robot 1, receives the #2 seat ring blank. After the #2 seat ring blank is received, the entire seat ring forming device 2 restarts for the next forming operation.

[0043] S2. After the transport robot 1 places the #1 and #2 seat ring blanks onto the two first wet repair workbenches 11a, the operator begins to perform the wet repair actions on the #1 and #2 seat ring blanks in sequence. After the wet repair actions on the #1 and #2 seat ring blanks are completed, the transport robot 1 picks up the #1 and #2 seat ring blanks and takes them to the coating machine 7 for coating. After both seat ring blanks have been coated with slurry, the transport robot 1 receives the inner liner demolding instruction and proceeds to an inner liner molding machine. The fork arm 102 carries the #1 seat ring blank and the #1 inner liner blank to perform a blank receiving action. After the blank receiving action is completed, the fork arm 102 retracts, and the inner liner molding machine starts the next molding action. The fork arm 102 rotates to another transport station facing another inner liner molding machine and carries the #2 seat ring blank and the #2 inner liner blank to complete the blank receiving action. After the receiving action is completed, the fork arm 102 retracts, and the inner liner molding machine immediately starts the next molding action.

[0044] S3. Next, the transport robot 1 places the #1 seat inner liner assembly and the #2 seat inner liner assembly onto the two first wet repair workbenches 11a respectively. The operator then begins to perform the wet repair actions on the #1 and #2 seat inner liner assemblies sequentially. After the first wet repair actions on the #1 and #2 seat inner liner assemblies are completed, the transport robot 1 picks up the #1 and #2 seat inner liner assemblies respectively and moves them to the coating machine 7 for coating. After the coating is completed, the transport robot 1 receives the outer shell demolding command and moves to the outer shell forming device 4. The fork arm 102, carrying the #1 seat inner liner assembly, completes the blank receiving action with the #1 outer shell blank. Then, the fork arm 102 retracts and rotates, carrying the #2 seat inner liner assembly, to complete the blank receiving action with the #2 outer shell blank. After the outer molding device 4 assists in completing the demolding action, the outer molding device 4 starts the next molding action again. At that time, a complete toilet blank injection molding action is completed, and then the next cycle begins.

[0045] S4. Simultaneously, after the transport robot 1 places toilet blank #1 and toilet blank #2 (i.e., the seat ring, inner liner, and outer casing assembly) onto the two first wet repair workbenches 11a, the operator begins to complete the first wet repair action of toilet blank #1 and toilet blank #2 in sequence. After the first wet repair action of toilet blank #1 and toilet blank #2 is completed, the transport robot 1 picks up toilet blank #1 and toilet blank #2 and moves them to the lower buffer rack 5 or the upper buffer rack 6, respectively. After toilet blanks #1 and #2 are left to stand and buffer for a period of time, the transport robot 1 receives the blank removal instruction and moves to the upper buffer rack 6 or the lower buffer rack 5 to pick up toilet blank #1 and toilet blank #2 in sequence. After the insertion and removal action is completed, they are moved to the conveyor line 8. At the same time, the blank turning machine 9 has prepared a dry pallet in preparation for the next blank turning before it starts turning blanks. After the billet is conveyed into the billet turning machine 9, the machine receives a turning instruction and completes the turning action. The toilet billet, carried by a drying tray, is conveyed via conveyor line 8 to the second wet repair workbench 11b. The operator turns to face the second wet repair workbench 11b and immediately performs the second wet repair action on the #1 toilet billet. Simultaneously, the #2 toilet billet is also turned over. After the second wet repair of the #1 toilet billet is completed, the second wet repair platform 11b descends and is conveyed to the receiving position, where it awaits transport to the next process by an AGV or other receiving device 12. After the second wet repair workbench 11b rises back to its working position, it rotates to receive the #2 toilet billet and performs a similar operation, and this cycle continues alternately.

[0046] S5. After the second wet repair of toilet blanks #1 and #2 is completed, the operator turns to face the first wet repair workbench 11a and begins the next cycle to prepare for the first wet repair of the next seat blank.
