[0045] For a thorough understanding of the present application, reference will be made to the following detailed description. It is apparent that the application can be practiced without the specific details disclosed herein. The preferred embodiments of the present application will be described in detail in the following description with reference to the drawings.

[0046] The present application provides a feeding device. The feeding device is used to move parts of a chassis of a container to a chassis welding platform. The parts of the chassis include a first bottom cross beam, a second bottom cross beam, and a gooseneck tank. The first bottom cross beam and the second bottom cross beam have different cross-sectional shapes. On the chassis, the length direction of the first bottom cross beam and the length direction of the second bottom cross beam both extend along the width direction of the chassis, and the length direction of the gooseneck tank extends along the length direction of the chassis.

[0047] The feeding device can move all the first bottom cross beams, the second bottom cross beams, and the gooseneck tank of one chassis to the chassis welding platform at one time, thereby facilitating the welding of the chassis.

[0048] For example, one chassis includes 24 first bottom cross beams, 3 second bottom cross beams, and 1 gooseneck tank. On the chassis, the first bottom cross beams, the second bottom cross beams, and the gooseneck tank are arranged in a part arrangement. The part arrangement is that, along the length direction of the chassis, a first part group, a second part group, a third part group, a second part group, a third part group, a second part group, a third part group, and a fourth part group are arranged in sequence.

[0049] The first part group includes 3 first bottom cross beams arranged at intervals along the length direction of the chassis. The second part group includes 1 second bottom cross beam. The third part group includes 7 first bottom cross beams arranged at intervals along the length direction of the chassis. The fourth part group includes 1 gooseneck tank.

[0050] The loading equipment can simultaneously transport 24 first bottom crossbeams, 3 second bottom crossbeams, and one gooseneck trough to the underframe welding platform. The first and second bottom crossbeams, as well as the gooseneck troughs, transported by the loading equipment are sequentially arranged according to the aforementioned component arrangement. The lengths of the first and second bottom crossbeams, as well as the gooseneck troughs, transported by the loading equipment, are aligned, while the gooseneck troughs are perpendicular to the length of the first bottom beams. This facilitates subsequent welding of the underframe.

[0051] like Figure 1 and Figure 2 As shown, the feeding device includes a main conveying component 110. The main conveying component 110 can be a conveyor belt. The main conveying component 110 is arranged along a first horizontal direction D1 ( Figure 1 In this way, the main conveying assembly 110 can move the parts placed on the main conveying assembly 110 along the first horizontal direction D1. The width direction of the main conveying assembly 110 is along the second horizontal direction D3 ( Figure 2 The first horizontal direction D1 is perpendicular to the second horizontal direction D3.

[0052] The running direction of the main conveying assembly 110 includes the main forward direction ( Figure 1 direction from left to right) and the main backward direction ( Figure 1 The main conveying assembly 110 is used to move the parts along the main forward direction to move the parts to the chassis welding platform.

[0053] When the first bottom beam, the second bottom beam and the gooseneck trough are placed on the main conveying component 110, the length direction of the first bottom beam is parallel to the second horizontal direction D3, the length direction of the second bottom beam is parallel to the second horizontal direction D3, and the length direction of the gooseneck trough is parallel to the first horizontal direction D1.

[0054] It should be noted that the operating direction is the direction in which the conveyor belt can move goods (parts). The operating direction of the main conveyor assembly 110 is parallel to the first horizontal direction D1. The operating direction of the first conveyor assembly 120 described below is parallel to the first horizontal direction D1. The operating direction of the second conveyor assembly 130 described below is parallel to the second horizontal direction D3.

[0055] The loading equipment includes a first conveyor assembly 120. The first conveyor assembly 120 may be a conveyor belt. The first conveyor assembly 120 extends horizontally. A plurality of first bottom crossbeams are stacked to form a first material pile. The first conveyor assembly 120 can be used to horizontally move the first material pile to a predetermined position within the first material pile.

[0056] When the first conveyor assembly 120 moves the first material pile, the length direction of the first bottom crossbeam of the first material pile is parallel to the width direction of the first conveyor assembly 120. The width direction of the first conveyor assembly 120 is perpendicular to the extension direction of the first conveyor assembly 120. The width direction of the first conveyor assembly 120 is parallel to the horizontal direction, and the width direction of the first conveyor assembly 120 is parallel to the extension direction of the first conveyor assembly 120.

[0057] The running direction of the first conveying assembly 120 includes the secondary forward direction ( Figure 1 from left to right) and the secondary backward direction ( Figure 1 The secondary forward direction is opposite to the secondary backward direction. The first conveying assembly 120 moves the first material pile along the secondary forward direction.

[0058] The loading equipment includes a second conveyor assembly 130. The second conveyor assembly 130 may be a conveyor belt. The second conveyor assembly 130 extends horizontally. A plurality of second bottom cross beams are stacked to form a second material pile.

The width direction of the second conveyor assembly 130 is parallel to the horizontal direction, and the width direction of the second conveyor assembly 130 is parallel to the extension direction of the second conveyor assembly 130.

[0060] like Figure 1 As shown, along the first horizontal direction D1 , there is a placement gap 190 between the second conveying assembly 130 and the first conveying assembly 120 .

[0061] The loading device also includes a first grabbing assembly 140. First grabbing assembly 140 is positioned above first conveyor assembly 120 in vertical direction D2. First grabbing assembly 140 is movably configured so that it can move directly above the first material pile at a predetermined location within the first material pile to grab the first bottom crossbeam located at the topmost layer of the first material pile. The grabbed bottom crossbeam is then moved to placement interval 190 for placement on main conveyor assembly 110.

[0062] The loading equipment also includes a second grabbing assembly 150. Second grabbing assembly 150 is positioned above second conveying assembly 130 in vertical direction D2. Second grabbing assembly 150 is movably configured so that it can move directly above the second material pile at a predetermined location within the second material pile to grab the second bottom crossbeam located at the topmost layer of the second material pile. The grabbed second bottom crossbeam is then moved to placement interval 190 for placement on main conveying assembly 110.

[0063] The loading device further comprises a controller. The controller is used for the operation of the loading device. The controller is configured to include the first bottom cross beam placing step (step 1), the second bottom cross beam placing step (step 3), and the first spacing step (step 2).

[0064] The controller places the first bottom cross beam on the main conveying assembly 110 through the first grabbing assembly 140 in step 1. The controller places the second bottom cross beam on the main conveying assembly 110 through the second grabbing assembly 150 in step 3.

[0065] Step 2 is located between step 1 and step 3. Step 2 is that the controller controls the main conveying assembly 110 to run for a first predetermined period of time. In this way, the controller can make the first bottom cross beam placed in step 1 and the second bottom cross beam placed in step 3 be spaced apart along the first horizontal direction D1 through step 2.

[0066] In the embodiment, the controller moves the first pile to a first pile predetermined position through the first conveying assembly 120, moves the second pile to a second pile predetermined position through the second conveying assembly 130, and then sequentially performs the first bottom cross beam placing step, the first spacing step, and the second bottom cross beam placing step to sequentially place the first bottom cross beam and the second bottom cross beam on the main conveying assembly 110, and then moves the first bottom cross beam and the second bottom cross beam to the chassis welding platform by the main conveying assembly 110. The operation of moving the first bottom cross beam and the second bottom cross beam to the chassis welding platform is simple and does not need manual operation, and the work efficiency is high.

[0067] Please refer to Figure 1 and Figure 2 The loading device comprises a support beam 191. The support beam 191 is fixedly arranged. The length direction of the support beam 191 extends along the first horizontal direction D1. Along the vertical direction D2, the support beam 191 is located above the main conveying assembly 110, the first conveying assembly 120, and the second conveying assembly 130.

[0068] The first grabbing assembly 140 comprises a first grabbing part 142, a first support rod 141, and a first mounting seat. The loading device further comprises a first horizontal driving assembly 192 and a first vertical driving assembly. The first mounting seat is movably connected to the support beam 191 along the first horizontal direction D1. The first horizontal driving assembly 192 is connected to the first mounting seat and the support beam 191 to drive the first mounting seat to move along the first horizontal direction D1.

[0069] For example, the first horizontal driving assembly 192 comprises a first rack and pinion driving structure. The first rack and pinion driving structure comprises a first motor, a first pinion and a first rack. The first motor is fixedly connected to the first mounting base. The length direction of the first rack extends along the first horizontal direction D1. The first rack is fixedly connected to the support beam 191. The first pinion is connected to the motor shaft of the first motor. The first pinion is engaged to the first rack. In this way, the first motor can drive the first mounting base to move along the first horizontal direction D1.

[0070] It can be understood that, in an embodiment not shown, the first horizontal driving assembly can also be a pneumatic cylinder, a hydraulic cylinder or a belt pulley structure, as long as it can drive the first mounting base to move along the first horizontal direction D1.

[0071] The length direction of the first support rod 141 extends along the vertical direction D2. The first support rod 141 is movably connected to the first mounting base along the vertical direction D2. The first vertical driving assembly is connected to the first support rod 141 and the first mounting base for driving the first support rod 141 to move along the vertical direction D2.

[0072] For example, the first vertical driving assembly comprises a second rack and pinion driving structure. The second rack and pinion driving structure comprises a second motor, a second pinion and a second rack. The second motor is fixedly connected to the first mounting base. The length direction of the second rack extends along the vertical direction D2. The second rack is fixedly connected to the first support rod 141. The second pinion is connected to the motor shaft of the second motor. The second pinion is engaged to the second rack. In this way, the second motor can drive the first support rod 141 to move along the vertical direction D2.

[0073] It can be understood that, in an embodiment not shown, the first vertical driving assembly can also be a pneumatic cylinder, a hydraulic cylinder or a belt pulley structure, as long as it can drive the first support rod to move along the vertical direction D2.

[0074] The first grabbing part 142 can be an electromagnet. The position of the first grabbing part 142 is higher than the first conveying assembly 120. The first grabbing part 142 is connected to the lower end of the first support rod 141 for adsorbing the first bottom cross beam. Under the action of the first horizontal driving assembly 192, the first grabbing part 142 can be moved along the first horizontal direction D1. Under the action of the first vertical driving assembly, the first grabbing part 142 can be moved along the vertical direction D2.

[0075] The first grabbing part 142 has a first initial position (P1). Figure 1 When the first grabbing part 142 is located at the first initial position and the first material pile is located at the first material pile predetermined position, the first grabbing part 142 is located directly above the first material pile.

[0076] Preferably, the first grabbing part 142 is a plurality (for example, 7). The plurality of first grabbing parts 142 are arranged in sequence along the first horizontal direction D1. In this way, each first grabbing part 142 is used to grab one first bottom cross beam. The plurality of first grabbing parts 142 grab a plurality of first bottom cross beams at the same time.

[0077] Preferably, the first conveying assembly 120 extends along the first horizontal direction D1. The width direction of the first conveying assembly 120 is parallel to the second horizontal direction D3. In this way, the first conveying assembly 120 can be used to move the first material pile along the first horizontal direction D1. The main conveying assembly 110 is located below the first conveying assembly 120. Along the second horizontal direction D3, the position of the first conveying assembly 120 is substantially the same as the position of the main conveying assembly 110. In this way, the main conveying assembly 110 and the first conveying assembly 120 can be staggered along the vertical direction D2. Thereby, the footprint of the feeding equipment can be reduced, and the space utilization rate can be improved.

[0078] Preferably, the feeding equipment further comprises a stop rod 160 and a stop rod driving motor. The stop rod driving motor is fixedly arranged. One end of the stop rod 160 is connected to the motor shaft of the stop rod driving motor. In this way, the stop rod driving motor can drive the stop rod 160 to rotate between a standing position (the position of the stop rod 160) and a lying position. When the stop rod 160 is in the standing position, the length direction of the stop rod 160 is substantially parallel to the vertical direction D2. When the stop rod 160 is in the lying position, the length direction of the stop rod 160 is substantially parallel to the extension direction of the first conveying assembly 120. Figure 1

[0079] Along the second horizontal direction D3, the stop rod 160 is located on the side of the first conveying assembly 120. In this way, when the first conveying assembly 120 moves the first material pile, the stop rod 160 in the standing position can block the first material pile, so that the first material pile abuts against the stop rod 160. At this time, the first material pile blocked by the stop rod 160 is located at the predetermined position of the first material pile.

[0080] As shown in FIG. 1, along the first horizontal direction D1, the stop rod 160 is located at a substantially middle position of the first conveying assembly 120. Thereby, on both sides of the stop rod 160 along the first horizontal direction D1, the first material pile can be arranged. Figure 1

[0081] The feeding equipment further comprises a pushing assembly 170. Along the subsequent advancing direction, the pushing assembly 170 is located downstream of the stop rod 160. The pushing assembly 170 is located above the first conveying assembly 120. The pushing assembly 170 is movably arranged along the vertical direction D2. Part of the pushing assembly 170 is retractable along the running direction of the first conveying assembly 120.

[0082] ​​When the first stack is located at the predetermined position, the advancing assembly 170 can be moved downward to the first bottom beam located at the uppermost layer of the first stack. Then, the part of the advancing assembly extends in the first horizontal direction D1 to apply a force to the first bottom beam located at the uppermost layer of the first stack. The force can press the first bottom beam located at the uppermost layer of the first stack against the guide rod 160. In this way, the first bottom beam located at the uppermost layer of the first stack can be fixed more effectively, so that the first gripping part 142 can grasp the first bottom beam more easily.

[0083] Specifically, the advancing assembly 170 includes an advancing part 172 and an advancing support rod 171. The feeding device further includes an advancing vertical driving assembly.

[0084] The length direction of the advancing support rod 171 extends along the vertical direction D2. The advancing vertical driving assembly is connected to the support beam 191 and the advancing support rod 171 for driving the advancing support rod 171 to move along the vertical direction D2.

[0085] For example, the advancing vertical driving assembly includes an advancing rack and pinion driving structure. The advancing rack and pinion driving structure includes an advancing motor, an advancing pinion and an advancing rack. The advancing motor is fixedly connected to the support beam 191. The length direction of the advancing rack extends along the vertical direction D2. The advancing rack is fixedly connected to the advancing support rod 171. The advancing pinion is connected to the motor shaft of the advancing motor. The advancing pinion is engaged with the advancing rack. In this way, the advancing motor can drive the advancing support rod 171 to move along the vertical direction D2.

[0086] It can be understood that, in an embodiment not shown, the advancing vertical driving assembly can be a pneumatic cylinder, a hydraulic cylinder or a belt pulley structure, as long as it can drive the advancing support rod 171 to move along the vertical direction D2.

[0087] The advancing part 172 can be a pneumatic cylinder. The advancing part 172 can be telescopic in the first horizontal direction D1. The advancing part 172 is connected to the advancing support rod 171.

[0088] Please refer to Figure 1 The second gripping assembly 150 includes a second gripping part 152, a second support rod 151 and a second mounting seat. The feeding device further includes a second horizontal driving assembly 193 and a second vertical driving assembly. The second mounting seat is movably connected to the support beam 191 along the first horizontal direction D1. The second horizontal driving assembly 193 is connected to the second mounting seat and the support beam 191 for driving the second mounting seat to move along the first horizontal direction D1.

[0089] For example, the second horizontal driving assembly 193 comprises a third rack and pinion driving structure. The third rack and pinion driving structure comprises a third motor, a third pinion and a third rack. The third motor is fixedly connected to the second mounting base. The length direction of the third rack extends along the first horizontal direction D1. The third rack is fixedly connected to the support beam 191. The third pinion is connected to the motor shaft of the third motor. The third pinion is engaged to the third rack. In this way, the third motor can drive the second mounting base to move along the first horizontal direction D1.

[0090] It can be understood that, in an embodiment not shown, the second horizontal driving assembly can be a pneumatic cylinder, a hydraulic cylinder or a belt pulley structure, as long as it can drive the second mounting base to move along the first horizontal direction D1.

[0091] The length direction of the second support rod 151 extends along the vertical direction D2. The second support rod 151 is movably connected to the second mounting base along the vertical direction D2. A second vertical driving assembly is connected to the second support rod 151 and the second mounting base for driving the second support rod 151 to move along the vertical direction D2.

[0092] For example, the second vertical driving assembly comprises a fourth rack and pinion driving structure. The fourth rack and pinion driving structure comprises a fourth motor, a fourth pinion and a fourth rack. The fourth motor is fixedly connected to the second mounting base. The length direction of the fourth rack extends along the vertical direction D2. The fourth rack is fixedly connected to the second support rod 151. The fourth pinion is connected to the motor shaft of the fourth motor. The fourth pinion is engaged to the fourth rack. In this way, the fourth motor can drive the second support rod 151 to move along the vertical direction D2.

[0093] It can be understood that, in an embodiment not shown, the second vertical driving assembly can be a pneumatic cylinder, a hydraulic cylinder or a belt pulley structure, as long as it can drive the second support rod 151 to move along the vertical direction D2.

[0094] The second grabbing part 152 can be an electromagnet. The position of the second grabbing part 152 is higher than the second conveying assembly 130.

Under the action of the second horizontal driving assembly 193, the second grabbing part 152 can be moved along the first horizontal direction D1. Under the action of the second vertical driving assembly, the second grabbing part can be moved along the vertical direction D2.

[0095] Preferably, the second grabbing part 152 is one. In this way, the second grabbing part 152 is used for grabbing one second bottom cross beam.

[0096] Preferably, the second conveying assembly 130 extends along a second horizontal direction D3. The width direction of the second conveying assembly 130 is parallel to the first horizontal direction D1. In this way, the second conveying assembly 130 can be used to move the second material pile along the second horizontal direction D3. The main conveying assembly 110 is located below the second conveying assembly 130. In this way, the main conveying assembly 110 and the second conveying assembly 130 can be staggered along the vertical direction D2, and the space can be used more effectively, and the footprint of the feeding device can be reduced.

[0097] The feeding device further comprises a stopper. The stopper is fixedly arranged. The stopper is located at the main conveying assembly 110. In this way, the stopper can block the second material pile, so that the second material pile is located at the second material pile predetermined position. The second material pile located at the second material pile predetermined position is located at the main conveying assembly 110.

[0098] Along the second horizontal direction D3, the second grabbing assembly 150 is located at the main conveying assembly 110. The second grabbing part 152 has a second initial position. When the second grabbing part 152 is located at the initial position and the second material pile is located at the second material pile predetermined position, the second grabbing part 152 is located directly above the second material pile. The second grabbing assembly 150 is movably arranged along the first horizontal direction D1. In this way, the second grabbing assembly 150 can be used to grab the second bottom cross beam of the second material pile located at the second material pile predetermined position. In this way, the structure of the second grabbing assembly 150 is simple.

[0099] The feeding device further comprises a gooseneck slot feeding assembly 180. The gooseneck slot feeding assembly 180 is located at the main conveying assembly 110. Part of the gooseneck slot feeding assembly 180 is movable along the vertical direction D2 for moving the gooseneck slot along the vertical direction D2. Part of the gooseneck slot feeding assembly 180 can rotate a predetermined angle in the horizontal direction for rotating the gooseneck slot a predetermined angle in the horizontal direction.

[0100] Specifically, the gooseneck slot feeding assembly 180 comprises a hydraulic cylinder, a gooseneck slot jacking support, a rotary motor, and a fixed part. The cylinder body of the hydraulic cylinder is fixedly arranged. The piston rod of the hydraulic cylinder is retractable along the vertical direction D2. The gooseneck slot jacking support is fixedly connected to the piston rod of the hydraulic cylinder. The rotary motor is fixedly connected to the gooseneck slot jacking support. The axis of the motor shaft of the rotary motor is parallel to the vertical direction D2. The fixed part is fixedly connected to the motor shaft of the rotary motor. The fixed part is provided with an electromagnet.

[0101] When the gooseneck slot is placed on the fixed part, the length direction of the gooseneck slot is parallel to the width direction of the main conveying assembly 110. The rotary motor can be rotated by about 90° to make the length direction of the gooseneck slot parallel to the running direction of the main conveying assembly 110.

[0102] Preferably, the gooseneck trough loading assembly 180, the first conveying assembly 120, and the second conveying assembly 130 are arranged in sequence along the main advancing direction. Thus, the structure of the loading device is simple.

[0103] As shown in FIG. 1, the steps performed by the controller include: Figure 3

[0104] Step 1, first bottom crossbeam placing step. Step 1 is followed by step 2.

[0105] Step 1 includes step 1.1, step 1.2, step 1.3, step 1.4, step 1.5, step 1.6, step 1.7, step 1.8, and step 1.9.

[0106] Step 1.1, the controller controls the advancing support rod 171 to move along the vertical direction D2 so that the advancing portion 172 moves to the first bottom crossbeam located at the uppermost layer of the first pile. Step 1.1 is followed by step 1.2.

[0107] Step 1.2, the controller controls the advancing portion 172 to extend close to the stop rod 160 so as to apply a force to the first bottom crossbeam located at the uppermost layer of the first pile. Step 1.2 is followed by step 1.3.

[0108] The force can press the first bottom crossbeam located at the uppermost layer of the first pile against the stop rod 160. In this way, the first bottom crossbeam located at the uppermost layer of the first pile can be fixed, facilitating the first grabbing portion 142 to grab the first bottom crossbeam.

[0109] Step 1.3, the controller controls the first grabbing portion 142 to move downward to the first pile. Step 1.3 is followed by step 1.4.

[0110] Step 1.3 is performed when the first grabbing portion 142 is located at the first initial position.

[0111] Step 1.4, the controller energizes the first grabbing portion 142. Step 1.4 is followed by step 1.5.

[0112] The energized first grabbing portion 142 can adsorb the first bottom crossbeam located at the uppermost layer of the first pile.

[0113] Step 1.5, the controller controls the first grabbing portion 142 to move upward so that the first bottom crossbeam grabbed by the first grabbing portion 142 moves away from the first pile or the first conveying assembly 120. Step 1.5 is followed by step 1.6.

[0114] ​The first stack has a multi-layer and multi-row structure. When the first bottom beam grabbed by the first grabbing part 142 is located at the bottom layer of the first stack, the controller controls the first bottom beam grabbed by the first grabbing part 142 to move away from the first stack. In other cases, the controller controls the first bottom beam grabbed by the first grabbing part 142 to move away from the first stack.

[0115] Step 1.6, the controller controls the first grabbing part 142 to move horizontally to the placement interval 190. After step 1.6, step 1.7 is performed.

[0116] Step 1.7, the controller controls the first grabbing part 142 to move downward to the main conveying assembly 110, and the controller stops supplying power to the first grabbing part 142. After step 1.7, step 1.8 is performed.

[0117] When the first bottom beam is located at the main conveying assembly 110, the controller stops supplying power to the first grabbing part 142. In this way, the adsorption of the first bottom beam by the first grabbing part 142 can be released, so that the first bottom beam is placed on the main conveying assembly 110.

[0118] Step 1.8, the controller controls the first grabbing part 142 to move upward and then move in the horizontal direction to return to the first initial position.

[0119] Step 1.9, the controller controls the pushing support rod 171 to return to the pushing initial position, and controls the pushing part 172 to shorten and reset.

[0120] The pushing support rod 171 has a pushing initial position. When the pushing support rod 171 is in the pushing initial position, the pushing part 172 is located above the lower surface of the first grabbing part 142 in the vertical direction D2. Step 1.9 can be performed after step 1.4. After step 1.8 and step 1.9, the current step 1 is completed.

[0121] Step 2, the first concession step. After step 2, step 3 is performed.

[0122] The controller controls the main conveying assembly 110 to run in the main retreat direction for a first predetermined time period, so that the first bottom beam placed on the main conveying assembly 110 in step 1 moves away from the placement interval 190. Step 2 can be performed after step 1.7.

[0123] Step 3, the second bottom beam placement step. After step 3, step 4 is performed.

[0124] Step 3 includes step 3.1, step 3.2, step 3.3, step 3.4, step 3.5, and step 3.6.

[0125] Step 3.1, the controller controls the second grabbing part 152 to move downwards to the second material pile. Step 3.1 is followed by Step 3.2.

[0126] Step 3.1 is performed when the second grabbing part 152 is at the second initial position.

[0127] Step 3.2, the controller supplies power to the second grabbing part 152. Step 3.2 is followed by Step 3.3.

[0128] The powered second grabbing part 152 can adsorb the second bottom beam located at the uppermost layer of the second material pile.

[0129] Step 3.3, the controller controls the second grabbing part 152 to move upwards so that the second bottom beam grabbed by the second grabbing part 152 is away from the second material pile or the second conveying assembly 130. Step 3.3 is followed by Step 3.4.

[0130] The second material pile has a multi-layer and multi-row structure. When the second bottom beam grabbed by the second grabbing part 152 is the last one of the second material pile, the controller controls the second bottom beam grabbed by the second grabbing part 152 to be away from the second conveying assembly 130. In other cases, the controller controls the second bottom beam grabbed by the second grabbing part 152 to be away from the second material pile.

[0131] Step 3.4, the controller controls the second grabbing part 152 to move horizontally to the placement interval 190. Step 3.4 is followed by Step 3.5.

[0132] Step 3.5, the controller controls the second grabbing part 152 to move downwards to the main conveying assembly 110, and the controller stops supplying power to the second grabbing part 152. Step 3.5 is followed by Step 3.6.

[0133] When the second bottom beam is at the main conveying assembly 110, the controller stops supplying power to the second grabbing part 152. In this way, the adsorption of the second bottom beam by the second grabbing part 152 can be released, so that the second bottom beam is placed on the main conveying assembly 110.

[0134] Step 3.6, the controller controls the second grabbing part 152 to move upwards and then move in the horizontal direction to return to the second initial position. After Step 3.6, the current Step 3 is completed.

[0135] Step 4, the second yielding step.

[0136] The controller controls the main conveying assembly to run in the main retreat direction for a second predetermined time period, so that the second bottom beam placed on the main conveying assembly 110 in Step 3 is away from the placement interval 190. Step 4 can be performed after Step 3.5.

[0137] Step 5, gooseneck trough placing step. Step 5 is performed after Step 4.

[0138] Steps 1, 2, 3, and 4 are performed repeatedly in sequence until all the first floor cross members and the second floor cross members (an example of a predetermined number of first floor cross members and second floor cross members) required for one container are placed completely to the main conveying assembly, then Step 5 is performed.

[0139] Before Step 5 is performed, the gooseneck trough can be placed to the fixed part by the crown block. Then Step 5 is performed.

[0140] Step 5 includes Step 5.1, Step 5.2, Step 5.3, Step 5.4, and Step 5.5.

[0141] Step 5.1, the controller controls the hydraulic cylinder to extend upward to lift the gooseneck trough until the gooseneck trough is above the main conveying assembly 110. Step 5.1 is followed by Step 5.2.

[0142] Step 5.2, the controller energizes the electromagnet of the fixed part. Step 5.2 is followed by Step 5.3.

[0143] The energized electromagnet can attract the gooseneck trough, thereby fixing the gooseneck trough.

[0144] Step 5.3, the controller controls the rotary motor to rotate the fixed part to rotate the gooseneck trough by a predetermined angle, so that the length direction of the gooseneck trough is parallel to the first horizontal direction D1. Step 5.3 is followed by Step 5.4.

[0145] Step 5.4, the controller stops supplying power to the electromagnet of the fixed part to release the attraction of the electromagnet of the fixed part to the gooseneck trough. Step 5.4 is followed by Step 5.5.

[0146] Stopping supplying power to the electromagnet of the fixed part can release the attraction of the electromagnet of the fixed part to the gooseneck trough.

[0147] Step 5.5, the hydraulic cylinder is shortened and reset.

[0148] During the process of shortening and resetting the hydraulic cylinder, the gooseneck trough is placed on the main conveying assembly 110. Step 5.5 is followed by the completion of the current Step 5.

[0149] Step 6, moving the parts to the welding predetermined position step.

[0150] The controller controls the main conveying assembly 110 to move in the main advancing direction to move the first floor cross member, the second floor cross member, and the gooseneck trough to the floor frame welding platform.

[0151] The controller also performs Step 0.1, the first material pile positioning step, before Step 1.

[0152] Before step 0.1 is performed, the first stack is placed on the first conveying assembly 120 by the crown block. At this time, the first stack is located upstream of the stopper 160 along the sub-advancing direction, and the stopper 160 is in the lying position.

[0153] Step 0.1 includes step 0.11, step 0.12, and step 0.13.

[0154] Step 0.11, the controller controls the first conveying assembly 120 to run along the sub-advancing direction to move the first stack downstream of the stopper 160 along the sub-advancing direction. Step 0.11 is followed by step 0.12.

[0155] Step 0.12, the controller controls the stopper 160 to rotate to the upright position. Step 0.12 is followed by step 0.13.

[0156] Step 0.13, the controller controls the first conveying assembly 120 to run along the sub-retreating direction.

[0157] The first conveying assembly 120 runs along the sub-retreating direction, thereby moving the first stack located downstream of the stopper 160 along the sub-advancing direction towards the stopper 160. In this way, the stopper 160 can block the first stack to stop the first stack at the first stack predetermined position. Thus, the first grabbing part 142 can conveniently grab the first bottom cross beam. Step 0.1 is completed after step 0.13.

[0158] Before step 3, the controller also performs step 0.2, the second stack positioning step.

[0159] Before step 0.2 is performed, the second stack is placed on the second conveying assembly 130 by the crown block.

[0160] Step 0.2, the second stack positioning step.

[0161] The controller controls the second conveying assembly 130 to work to move the second stack to the stop block, which can block the second stack to stop the second stack at the second stack predetermined position. Thus, the second grabbing part 152 can conveniently grab the second bottom cross beam.
