The transition device 5 is used to transfer workpieces from the lateral detection device 10 to the placement station 610 of the rotary detection device 6. A transition device 5 is also provided on one side of the take - out station 617. This transition device 5 is used to transfer workpieces from the take - out station 617 of the rotary detection device 6 to the NG judgment device 7. The NG judgment device 7 and the robotic arm 8 are both installed on the workbench 1. The robotic arm 8 is used to take out the qualified workpieces that have passed the qualified judgment in the NG judgment device 7 to the recycling side.

[0062] First, the workpiece is fed into the workbench 1 by the feeding device 2, and the workpiece is transferred into the lateral detection device 10 by the transfer device 3.

Among them, the unqualified workpieces are directly clamped into the NG box 1005 by the progressive device 4; then the workpiece on the placement table 1006 is clamped and placed on the placement station 610 of the rotary detection device 6 by the transition device 5, and then the rotary detection device 6 drives the workpiece to be detected one by one in the rotary detection device 6; finally, the workpiece is clamped from the rotary detection device 6 to the NG judgment device 7 by the second transition device 5. The NG judgment device 7 retains the qualified workpieces, and then the qualified workpieces are transferred to the recycling side by the manipulator 8.

[0063] Please refer to Figure 7 , the feeding device 2 includes a cylinder 201. A moving block 203 is provided on the cylinder 201. A linear guide 202 is installed on the cylinder 201. The moving block 203 is installed on the cylinder 201 and the linear guide 202. A placement table 204 is installed on the moving block 203. The photoelectric sensor 205 is installed on the workbench 1 through the sensor bracket 206, and the photoelectric sensor 205 is located at one end of the cylinder 201 close to the transfer device 3. The photoelectric sensor 205 is used to sense whether the workpiece reaches one end of the cylinder 201 close to the transfer device 3, so as to facilitate the transfer device 3 to transfer the workpiece.

[0064] Please refer to Figure 8 , the transfer device 3 includes a support block 301, a cylinder 302 and a linear guide 303 installed on the support block 301. A moving block 306 is installed on the cylinder 302 and the linear guide 303. A cylinder 304 is installed on the moving block 306. At the same time, a connecting block 305 is installed on the cylinder 304. A rotary cylinder 307 is installed on the connecting block 305. A pneumatic gripper 308 is installed on the rotary cylinder 307.

[0065] In the initial state, the pneumatic gripper 308 is in the open state. When the photoelectric sensor 205 senses the workpiece, the cylinder 302 is opened to move the pneumatic gripper 308 directly above the placement table 204. Subsequently, the cylinder 304 is opened to place the workpiece in the pneumatic gripper 308. Then the pneumatic gripper 308 is opened to clamp the workpiece directly above the lateral detection device 10. Finally, the rotary cylinder 307 is opened to rotate the workpiece to the corresponding position and then place it on the lateral detection device 10.

[0066] Please refer toFigure 9 The horizontal detection device 10 includes a core-pulling hole detector 1001, a sealing ring detector 1002, a buckle detector 1003, a sensing surface protrusion detector 1004, an NG box 1005, and a placing table 1006, which are sequentially installed on the workbench 1 starting from one end close to the transfer device 3. At the same time, the distances from the core-pulling hole detector 1001 to the sealing ring detector 1002, from the sealing ring detector 1002 to the buckle detector 1003, from the buckle detector 1003 to the sensing surface protrusion detector 1004, and from the sensing surface protrusion detector 1004 to the placing table 1006 are all equal. At the same time, the NG box 1005 is located at the middle position between the sensing surface protrusion detector 1004 and the placing table 1006.

[0067] Please refer to Figure 1 and 9 Among them, the core-pulling hole detector 1001 includes a placing table 1006, cameras 1009 respectively installed on both sides of the placing table 1006 through a camera mounting base 1008, a lamp ring 1007 located between the cameras 1009 and the placing table 1006 and mounted on the camera mounting base 1008, and the cameras 1009 on both sides are on the same horizontal line. By photographing the shapes of the core-pulling holes 1101 on both sides of the workpiece with the cameras 1009, it is judged whether the core-pulling hole part of the workpiece is qualified. There may be cracks in any of the core-pulling holes 1101. Therefore, by taking pictures at the core-pulling holes 1101, it is judged whether there are cracks at the core-pulling holes 1101. When there are cracks at the core-pulling holes 1101, the workpiece is judged as unqualified.

[0068] Please refer to Figure 1 、 2 、9 and 10, the sealing ring detector 1002 includes a placing table 1006, a camera 1009 installed on one side of the placing table 1006 through a camera mounting base 1008, and a baffle 1011 located on the other side of the placing table 1006 and mounted on the workbench 1 to facilitate the focusing of the camera 1009. By photographing the position of the O-ring 1102 of the workpiece with the camera 1009, it is judged whether the sealing ring part of the workpiece is qualified. There may be situations where the O-ring 1102 is missing or over-installed on the workpiece. When the above situations exist in the photographed pictures, the workpiece is judged as unqualified.

[0069] Please refer to Figure 1 、 2 、9 and 11, the buckle detector 1003 includes a placing table 1006 and a 3D camera 1010 located on one side of the placing table 1006 and mounted on the workbench 1. By photographing the position of the buckle 1103 of the workpiece with the 3D camera 1010, it is judged whether the buckle part of the workpiece is qualified. There may be situations where the buckles 1103 on both sides of the workpiece are short of material or broken. When the above situations exist in the photographed pictures, the workpiece is judged as unqualified.

[0070] Please focus on 1, 2 and 9. The induction surface protrusion detection 1004 includes a shelf 1006, a camera 1009 installed on one side of the shelf 1006 through a camera mounting seat 1008, and a telecentric lens installed on the camera 1009, which can more carefully photograph the position of the induction surface 1104, and a baffle 1011 located on the other side of the shelf 1006 and installed on the workbench 1. The camera 1009 photographs the position of the workpiece induction surface 1104 to determine whether the workpiece induction surface is qualified. The workpiece induction surface 1104 may have a protrusion. When the above situation exists in the photographed photo, it is judged as an unqualified workpiece.

[0071] Please focus on Figure 12 The progressive device 4 includes a fixed plate 402 installed on the workbench 1 through a fixed support 412, a motor 401 is installed on the fixed plate 402, and a limit block 405 installed on the fixed plate 402, the limit block 405 is provided with a limit groove 406, the motor 401 is located at the midline position of the limit groove 406, the limit groove 406 is a 冂 shape, the sliding block is located in the limit groove 406, and the linear guide rail 3 403 is horizontally installed on the fixed plate 402, the linear guide rail 404 is vertically installed on the linear guide rail 3 403, the moving block 3 408 is installed on the linear guide rail 4 404, and the moving block 3 408 is installed on the sliding block 408 through the connecting shaft 409. The movable block is mounted on the movable block, and the sliding block is installed on the motor 1 401 through the connecting shaft 409. Therefore, when the motor 1 401 is turned on, the motor 1 401 drives the sliding block to move along the limit groove 406, thereby driving the movable block 3 408 to move along the limit groove 406; a fixed seat 410 is installed on the movable block 3 408, and four pneumatic clamps 2 411 are evenly installed on the fixed seat 410. The four pneumatic clamps 2 411 respectively correspond to the core pulling hole detection 1001, the sealing ring detection 1002, the buckle detection 1003 and the sensing surface protrusion detection 1004. At the same time, the lateral length of the limit groove 406 is equal to the distance between the core pulling hole detection 1001 and the sealing ring detection 1002.

[0072] In the initial state, the four pneumatic jaws II 411 of the progressive device 4 respectively rest on the seal ring detection 1002, the buckle detection 1003, the sensing surface protrusion detection 1004 and the placement table 1006. Therefore, when the photoelectric sensor I 205 senses the workpiece, the transfer device 3 clamps the workpiece to the core hole detection 1001 and starts to detect the core hole 1101 of the workpiece. After the detection is completed, the motor I 401 is started, and the progressive device 4 transfers the workpiece that has completed the core hole detection to the seal ring detection 1002. At the same time, the transfer device 3 clamps the next workpiece to the core hole detection 1001. The above operations are repeated until all the detections of the workpiece on the lateral detection device 10 are completed. Subsequently, it is judged whether the workpiece is qualified by photos. If the workpiece is unqualified, when the motor I 401 moves the moving block III 408 to the midpoint position of the limit groove 406, the pneumatic jaw II 411 directly above the NG box I 1005 is opened at this time, so that the unqualified workpiece falls into the NG box I 1005. If the workpiece is qualified, the motor I 401 sends the workpiece to the placement table 1006. The placement table 1006 here mainly plays a transitional role, so as to facilitate the subsequent transfer device 5 to transfer the workpiece and transfer the workpiece to the rotary detection device 6 for workpiece detection.

[0073] Please refer to Figure 13 , the transfer device 5 includes a support block II 508, a linear guide V 502 and a cylinder IV 501 installed on the support block II 508. At the same time, a moving block IV 505 is installed on the linear guide V 502 and the cylinder IV 501. A cylinder V 503 is installed on the moving block IV 505. A connecting block II 506 is movably installed on the moving block IV 505 through a linear guide VI 507. The connecting block II 506 is installed on the cylinder V 503. At the same time, a pneumatic jaw III 504 is installed on the connecting block II 506.

[0074] In the initial state, the pneumatic jaw III 504 is located directly above the rotary detection device 6. When the workpiece is on the placement table 1006, the cylinder IV 501 is started, so as to drive the pneumatic jaw III 504 to reach directly above the placement table 1006. Subsequently, the cylinder V 503 is started to bring the pneumatic jaw III 504 close to the workpiece. Then the pneumatic jaw III 504 is started to clamp the workpiece. Finally, the cylinder IV 501 is started to send the workpiece to the rotary detection device 6.

[0076] The cam divider is used as an intermittent divider to intermittently turn the workpiece to eight workstations, so that the rotating disk 607 can be used as a dividing disk.

[0077] The guide post detection device 619 is composed of a camera 1009 mounted on the fixed plate 606 through a camera mounting seat 1008, and a light ring 1007 located between the camera 1009 and the support frame 613. Figure 15 , the position of the workpiece guide column 1105 is photographed by camera 1009 to determine whether the workpiece guide column 1105 is qualified. The workpiece guide column 1105 may not be in the specified position. When the above situation exists in the photograph taken, it is determined to be an unqualified workpiece.

[0078] Please focus on Figure 1 The burr detection device 620 is composed of a 3D camera 1010 and its mounting base. The camera 1009 photographs the position 1106 where burrs will appear on the workpiece to determine whether the workpiece is qualified. If burrs appear on the workpiece in the photograph, it is determined to be an unqualified workpiece.

[0079] Please focus on Figure 1 and 2, the marking detection device 621 consists of a camera 1009 mounted on the fixed disk 606 through a camera mounting base 1008, and a lamp ring 1007 located between the camera 1009 and the support frame 613. The camera 1009 takes pictures of the workpiece marking position 1107 to determine whether the workpiece is qualified. There may be abnormal marking and engraving positions or offset of the coding mark at the workpiece marking position 1107, that is, the two-dimensional code touches the mold clamping line. When the above situation exists in the taken photo, the workpiece is judged as unqualified.

[0080] Please refer to Figure 1 , 2 and 16, the induction surface foreign object detection device 622 includes a light condensing auxiliary part 6221 and a camera 1009 located directly below the induction surface foreign object detection station 616 in sequence. The light condensing auxiliary part 6221 is hemispherical, and there is a light condensing hole 6222 on the light condensing auxiliary part 6221. The camera 1009 is located directly below the light condensing hole 6222. The light condensing auxiliary part 6221 is installed on the workbench 1 through a bracket 6224, and the camera 1009 is installed on the first electric lead screw 6225 through a camera mounting base 1008. The first electric lead screw 6225 is installed on the workbench 1, and the camera 1009 can adjust the focusing distance through the first electric lead screw 6225. The camera 1009 takes pictures at the position of the workpiece induction surface 1104 to determine whether the workpiece induction surface is qualified. There may be exposed white or foreign objects on the workpiece induction surface 1104, that is, the color on the induction surface 1104 is inconsistent. When the above situation exists in the taken photo, the workpiece is judged as unqualified.

[0081] When the transfer device 5 moves the workpiece from the shelving table 1006 to the placement station 610 of the rotary detection device 6, the second motor 602 is started, which drives the rotary disk 607 to perform intermittent rotation operations, so as to perform guide post detection, flash detection, marking detection and induction surface foreign object detection in sequence. When all the detections of the workpiece on the rotary detection device 6 are completed; then the detected workpiece is sent to the NG judgment device 7 through the second transfer device 5, and the NG judgment device 7 is used to separately process qualified workpieces and unqualified workpieces.

A rotating frame 708 is located inside the fixing frame 707, and the rotating frame 708 is movably installed on the fixing frame 707 through a shaft 706 and a bearing. A second rotary cylinder 711 is installed at the end of the shaft 706. The rotating frame 708 shown in the figure is in a horizontal state. In the initial state, the rotating frame 708 is in a vertical state, that is, the top surface of the rotating frame 708 faces upward.

[0083] The top surface of the rotating frame 708 is provided with a clamping hole 710, and the clamping hole 710 is used to place the workpiece. The rotating frame 708 is also equipped with a pneumatic clamp 709, and the pneumatic clamp 709 is used to clamp the workpiece when the workpiece is placed in the clamping hole 710 to prevent the workpiece from falling. At the same time, the bottom surface of the rotating frame 708 does not exceed the position of the clamping hole 710. Therefore, when the rotating frame 708 is in a vertical state and the pneumatic clamp 709 releases the workpiece, the workpiece can directly detach from the NG judgment device 7.

[0084] Please focus on Figure 19 and Figure 4 The NG judgment device 7 also includes an NG hole 702 provided on the workbench 1, and an NG box 2 712 installed directly below the NG hole 702 through a box rack 713. When the rotating rack 708 is in a vertical state and the pneumatic clamp 5 709 releases the workpiece, the workpiece passes through the NG hole 702 and falls into the NG box 2 712.

[0085] In the initial state, the rotating frame 708 is in a vertical state and the cylinder six 701 is in a full stroke state; when the photos taken by the camera are transmitted to the controller and it is determined whether the workpiece is qualified, the second transition device 5 sends the inspected workpiece to the clamping hole 710 in the NG judgment device 7, and at the same time, the pneumatic clamp five 709 is turned on to clamp the workpiece. When the workpiece is judged to be an unqualified workpiece, the pneumatic clamp five 709 is turned on to loosen the workpiece, and the workpiece passes through the NG hole 702 and falls into the NG box two 712; when the workpiece is judged to be a qualified workpiece, the rotating cylinder two 711 is turned on, and the rotating cylinder two 711 drives the rotating frame 708 to rotate, so that the rotating frame 708 is in a horizontal state, and at the same time, the cylinder six 701 is turned on, and the cylinder six 701 drives the entire fixed frame 707 to retract, and then waits for the robot arm 8 to grab the workpiece.

[0086] Please focus on Figure 20 The robot 8 includes an industrial robot 801 and a pneumatic gripper 802 mounted on the industrial robot 801. The industrial robot 801 moves the pneumatic gripper 802 to the workpiece in the rotating frame 708, opens the pneumatic gripper 802, thereby clamping the workpiece, and then the industrial robot 801 moves the workpiece out to the recovery side.

As the central control system, the PLC uses a touch screen to realize the program input and operation control of the whole machine, and realizes the full automation of the transportation process. The control system can be used as a system that connects each actuator to move according to a logical trajectory, and controls the actuator to operate according to the required operation steps through programming.

[0089] Based on the above device, Embodiment 1 of the present invention also proposes an operation method of using the detection device of an automotive sensor, including the following steps:

[0090] Step 1, first, the workpiece is fed into the workbench 1 by the feeding device 2, and the workpiece is transferred into the horizontal detection device 10 by the transfer device 3;

[0091] Step 2, the horizontal detection device 10 cooperates with the progressive device 4 to sequentially perform core hole detection 1001, seal ring detection 1002, buckle detection 1003 and induction surface protrusion detection 1004 on the workpiece. The progressive device 4 drives the workpiece to perform the detection in the horizontal detection device 10 one by one, and finally falls onto the placement table 1006. The unqualified workpieces are directly clamped into the NG box 1 1005 by the progressive device 4; the qualified workpieces are clamped by the transition device 5 and placed on the placement station 610 of the rotary detection device 6;

[0092] Step 3, then the rotary detection device 6 drives the workpiece to sequentially perform guide post detection, burr detection, marking detection and induction surface foreign object detection;

[0093] Step 4, finally, the workpiece is clamped from the rotary detection device 6 to the NG judgment device 7 by the second transition device 5. The unqualified workpieces directly pass through the NG judgment device 7 and fall into the workbench 1, while the qualified workpieces are left by the NG judgment device 7, and then the qualified workpieces are transferred to the recycling side by the manipulator 8.

[0094] Embodiment 2

[0095] Such as Figures 3 - 5As shown in the figure, a detection device for an automotive sensor disclosed in the second embodiment further includes a recycling device 9 installed on the workbench 1. Except for this, other devices, their installation positions, and usage methods are the same as those in the first embodiment.

[0096] The manipulator 8 moves the qualified workpieces into the recycling device 9.

[0097] Please refer to Figure 21 for key reference. The recycling device 9 includes two tray transportation devices 902 installed inside the workbench 1 with one end passing through the workbench 1. One of the tray transportation devices 902 is used to place empty trays, and the other tray transportation device 902 is used to place qualified workpieces. And an empty tray in one tray transportation device 902 is transported to the other tray transportation device 902 through a transfer tray device 901 between the two tray transportation devices 902.

[0098] Please refer to Figure 22 for key reference. The transfer tray device 901 includes a single-axis robot 9011 installed on the workbench 1 through a transfer support frame 9012, a transfer seat 9013 installed on the single-axis robot 9011, a connecting seat 9015 movably installed on the transfer seat 9013 through a linear guide rail eight 9014 and a cylinder seven 9015, a rotary cylinder three 9016 installed on the transfer seat 9013, a suction cup seat 9017 installed on the rotary cylinder three 9016. The suction cup seat 9017 is in an X shape. At the same time, a suction cup 9018 is installed at each end of the suction cup seat 9017. At the same time, a proximity switch 9019 is installed on the side of the rotary cylinder three 9016. The proximity switch 9019 is used to judge whether the sucked tray is in the correct or reverse direction. When it is judged to be in the reverse direction, the rotary cylinder three 9016 is turned on, so that the tray can be turned back to the correct direction.

[0099] Please refer to Figure 21 for key reference. The tray transportation device 902 includes an electric lead screw two 9021, the electric lead screw two 9021 is installed on the workbench 1 through a lead screw seat 9022, a tray seat 9028 is installed on the electric lead screw two 9021 through a support rod 9029 and a flange seat 90210. The tray is placed on the tray seat 9028. Angle steels 9024 are located at the four corners of the tray seat 9028. At the same time, the angle steels 9024 are installed on the workbench 1. The angle steels 9024 are used to limit the up and down movement of the tray. At the same time, the angle steel 9024 at one corner of the tray seat 9028 is lower than the tray seat 9028, while the angle steels 9024 at the other three corners are higher than the tray seat 9028, so as to facilitate tray positioning. A clamping block 9027 is provided at the angle steel 9024 lower than the tray seat 9028. The clamping block 9027 is installed on a cylinder eight 9025, and the cylinder eight 9025 is installed on the lead screw seat 9022 through a cylinder seat 9026.

[0100] Therefore, when the empty tray is placed on the tray seat 9028, the cylinder eight 9025 is activated, and the empty tray is moved to the same position through the chuck 9027, facilitating the positioning of the tray transport device 902.

[0101] The manipulator 8 places the workpieces one by one into the trays on the tray transport device 902. When there is no empty space in the trays here, the single-axis robot 9011 and the electric lead screw two 9021 are activated. The electric lead screw two 9021 moves the tray down one station. At the same time, the single-axis robot 9011 drives the suction cup 9018 to move directly above another tray transport device 902 where the empty tray is placed. The suction cup 9018 sucks the empty tray to the tray transport device 902 without empty space. At this time, this empty tray replaces the position of the previous tray, enabling the manipulator 8 to continue transporting qualified workpieces. At the same time, the electric lead screw two 9021 at the other tray transport device 902 is activated, causing the empty tray to rise one station, facilitating the next transfer of the tray device 901 to suck the empty tray.

[0103] Based on the above device, Embodiment 2 of the present invention also proposes an operation method of using the detection device of an automotive sensor, including the following steps:

[0104] Step 1, first, the workpiece is fed into the workbench 1 by the feeding device 2, and the workpiece is transferred into the horizontal detection device 10 by the transfer device 3. The workpiece is continuously fed into the horizontal detection device 10.

[0105] Step 2: The horizontal detection device 10, in cooperation with the progressive device 4, sequentially performs core-pulling hole detection 1001, sealing ring detection 1002, buckle detection 1003, and induction surface protrusion detection 1004 on the workpieces. The progressive device 4 drives the workpieces one by one to be detected in the horizontal detection device 10 and finally drops them onto the placement table 1006. The unqualified workpieces are directly clamped by the progressive device 4 and placed into the NG box 1005; the qualified workpieces are clamped by the transfer device 5 and placed on the placement station 610 of the rotary detection device 6;

[0106] Step 3: Then, the rotary detection device 6 drives the workpieces to sequentially perform guide post detection, burr detection, marking detection, and induction surface foreign object detection;

[0107] Step 4: Subsequently, the second transfer device 5 clamps the workpieces from the rotary detection device 6 and places them into the NG judgment device 7. The unqualified workpieces directly pass through the NG judgment device 7 and fall onto the workbench 1, while the qualified workpieces are retained by the NG judgment device 7. Subsequently, the manipulator 8 transfers the qualified workpieces to the recycling device 9;

[0108] Step 5: Finally, the manipulator 8 places the workpieces one by one into the trays on the tray transportation device 902. When there is no empty space in the trays here, the transfer tray device 901 and this tray transportation device 902 are activated. The transfer tray device 901 transfers the empty tray on another tray transportation device 902 to the position of the previous tray on this tray transportation device 902. Subsequently, another tray transportation device 902 is activated, and another tray transportation device 902 ejects the subsequent empty tray to the position of the previous empty tray.

[0109] This device realizes the continuous detection operation of a large number of sensor housings, realizes automatic operation throughout the process, reduces the consumption of manpower, and improves the operation efficiency at the same time.

[0110] This device realizes eight detections on the automotive sensor housing, namely core-pulling hole detection 1001, sealing ring detection 1002, buckle detection 1003, induction surface protrusion detection 1004, guide post detection, burr detection, marking detection, and induction surface foreign object detection, ensuring the quality of the automotive sensor housing to the greatest extent. At the same time, the detected workpieces are classified as qualified and unqualified, and finally all the qualified workpieces are orderly recycled into the trays, realizing the whole-process automatic detection and recycling.

At the same time, the angle steel (9024) at one corner of the pallet base (9028) is lower than the pallet base (9028), while the angle steels (9024) at the other three corners are higher than the pallet base (9028). A clamping block (9027) is provided at the angle steel (9024) lower than the pallet base (9028). The clamping block (9027) is installed on a cylinder VIII (9025). The cylinder VIII (9025) is installed on the lead screw base (9022) through a cylinder base (9026).

7. An operation method of using the detection device for an automotive sensor according to claim 1, characterized in that, It includes the following steps: S1. First, the workpiece is fed into the workbench (1) by a feeding device (2), and the workpiece is transferred into a lateral detection device (10) by a transfer device (3). The workpiece is continuously fed into the lateral detection device (10). S2. The lateral detection device (10) and a progressive device (4) are used to sequentially perform core hole detection (1001), sealing ring detection (1002), buckle detection (1003), and induction surface protrusion detection (1004) on the workpiece. The progressive device (4) drives the workpiece to be detected in the lateral detection device (10) one by one, and finally falls onto a shelving table (1006). Among them, the unqualified workpieces are directly clamped into an NG box I (1005) by the progressive device (4); the qualified workpieces are clamped and placed on a placement station (610) of a rotary detection device (6) by a transition device (5). S3. Then, the rotary detection device (6) drives the workpiece to sequentially perform guide post detection, burr detection, marking detection, and induction surface foreign object detection. S4. Subsequently, the workpiece is clamped from the rotary detection device (6) into an NG judgment device (7) by a second transition device (5). Among them, the unqualified workpieces directly pass through the NG judgment device (7) and fall into the workbench (1), while the qualified workpieces are left by the NG judgment device (7). Subsequently, the qualified workpieces are transferred to a recycling device (9) by a manipulator (8). S5. Finally, the manipulator (8) places the workpieces into the pallets on the pallet transportation device (902) one by one. When there is no empty space in the pallets here, the transfer pallet device (901) and this pallet transportation device (902) are started. The transfer pallet device (901) transfers the empty pallet on another pallet transportation device (902) to the upper pallet of this pallet transportation device (902). Subsequently, another pallet transportation device (902) is started, and another pallet transportation device (902) ejects the subsequent empty pallet to the position of the previous empty pallet.
