[0035] Currently, in the logistics and transportation operations of parts in the workshop, some parts need to be placed in part boxes for transportation. Part boxes with parts are called full part boxes, and parts boxes without parts are called empty part boxes. When transporting the part boxes, the part box transport trolley needs to first load the empty part boxes from the production line, and then move to the empty part box receiving shelf, unload the empty part boxes to the empty part box receiving shelf, and then move to the full part box sending shelf, load the full part boxes onto the part box transport trolley, and then transport them to the production line by the part box transport trolley, and so on.

[0036] According to the observation and research of the application, it was found that in the process of unloading empty parts boxes to the empty parts box receiving shelf and receiving real parts boxes at the real parts box sending shelf, since the parts box transport trolley needs to unload its own empty parts box first and then receive the real parts box, and the parts box transport trolley needs to move forward slowly during the unloading and receiving process, there is a lot of time waste in this process, which reduces the overall work efficiency of the parts logistics transportation operation.

[0037] In view of this, the present invention proposes a quick exchange trolley 100 to solve the above technical problems.

[0038] See also Figure 1 and Figure 2In one embodiment of the present invention, the quick exchange trolley 100 includes a traveling frame 1, a cargo box loading platform 2 and an empty box unloading platform 3, wherein the traveling frame 1 is provided with an opening side O and a stop side S which are arranged opposite to each other. When the quick exchange trolley 100 exchanges parts boxes with the shelf, the opening side O faces the shelf; at least one cargo box loading platform 2 is provided, and the cargo box loading platform 2 includes a loading entrance 23 and a loading rail 21, the loading entrance 23 is provided at the opening side O, and the loading rail 21 extends from the opening side O to the stop side S; at least one empty box unloading platform 3 is also provided, and the empty box unloading platform 3 is provided above the cargo box loading platform 2, the empty box unloading platform 3 includes an unloading outlet 33 and an unloading rail 31, the unloading outlet 33 is provided at the opening side O, and the unloading rail 31 extends from the opening side O to the stop side S.

[0039] Specifically, two platforms are mounted on the traveling frame 1. The upper platform is an empty container unloading platform 3, used to load empty component containers from the production line or other locations and transport them to the shelves for unloading. The lower platform is a cargo container loading platform 2, used to receive full component containers from the shelves and transport them to the production line or other locations. To facilitate loading and unloading of component containers, one side of the traveling frame 1 is an opening side O. Opening side O is unobstructed by the traveling frame 1's rods, allowing for the exchange of empty and full component containers. Opposite opening side O is a stop side S of the traveling frame 1, which prevents component containers from falling off the traveling frame 1. Brackets with the same function as the stop side S are also installed on the front and rear sides of the traveling frame 1. On the open side O of the traveling frame 1, a loading entrance 23 is formed between the cargo box loading platform 2 and the traveling frame 1, and an unloading exit 33 is formed between the empty box unloading platform 3 and the traveling frame 1. The size of the loading entrance 23 is larger than the size of the actual part box, while the size of the unloading exit 33 is larger than the size of the empty part box, so as to facilitate the loading of actual part boxes and the unloading of empty part boxes. After the rapid exchange trolley 100 is docked with the shelf, the actual part box enters the cargo loading platform through the loading entrance 23 and is located above the loading track 21. The loading track 21 facilitates the sliding of the actual part box in the cargo loading platform, reducing the difficulty of loading the actual part box. Similarly, an unloading track 31 is also provided on the empty box unloading platform 3. The unloading track 31 enables the empty part box to slide on the empty box unloading platform 3, so that after the rapid exchange trolley 100 is docked with the shelf, the empty part box slides from the unloading track 31 through the unloading exit 33 into the shelf, thereby facilitating the unloading of the empty part box. It should be noted that the shelf in the above embodiment also has two platforms: an empty box platform and a full box platform, respectively used to receive empty parts boxes and deliver full parts boxes. The positions of the two platforms correspond to the empty box unloading platform 3 and the cargo box loading platform 2 in this embodiment, with the empty box platform located above the full box platform. When receiving empty parts boxes, the empty box platform is lower than the empty box unloading platform 3 to facilitate gravity unloading of the empty parts boxes. When delivering full parts boxes, the full box platform is higher than the cargo box loading platform 2 to facilitate gravity loading of the full parts boxes.

[0040] In the embodiment provided by the present invention, a cargo box loading platform 2 and an empty box unloading platform 3 located above the cargo box loading platform 2 are provided on the traveling frame 1, and a loading entrance 23 is provided on the open side O of the traveling frame 1 to connect to the cargo box loading platform 2, and an unloading exit 33 is provided to connect to the empty box unloading platform 3, and loading rails 21 and unloading rails 31 are provided on the cargo box loading platform 2 and the empty box unloading platform 3, respectively, to facilitate the sliding of the component boxes. Through this arrangement, when the rapid exchange trolley 100 exchanges component boxes with the shelf, the open side O is close to the shelf, the empty component box slides from the empty box unloading platform 3 to the shelf, and the full component box slides from the shelf to the cargo box loading platform 2. This process is carried out simultaneously and does not interfere with each other. In this way, there is no need to unload the empty component box first and then load the full component box, which greatly reduces the component box exchange time, thereby improving the overall work efficiency of the component logistics and transportation operation.

[0041] Furthermore, in one embodiment of the present invention, the cargo box loading platform 2 further includes a first support platform 22, a loading rail 21 is mounted on the top surface of the first support platform 22, and at the bottom of the first support platform 22, the traveling frame 1 is provided with a first support rod 11, the first support rod 11 is connected to the first support platform 22 via a bearing, and the first support platform 22 can rotate around the first support rod 11; at the same time, the empty box unloading platform 3 further includes a second support platform 32, an unloading rail 31 is mounted on the top surface of the second support platform 32, and at the bottom of the second support platform 32, the traveling frame 1 is provided with a second support rod 12, the first support rod 12 is connected to the second support platform 32 via a bearing, and the second support platform 32 can rotate around the first support rod 12. For details, please refer to Figure 1 、 Figure 3 and Figure 4The cargo box loading platform 2 includes a first supporting platform 22, which is equivalent to the skeleton of the cargo box loading platform 2, and a loading rail 21 is installed on its top surface. The top of the loading rail 21 is usually used to place the actual parts box; below the first supporting platform 22, a layer of rods of the walking frame 1 is provided, wherein a first support rod 11 is provided at the center line position of the first supporting platform 22, and a bearing is fixedly sleeved on the first support rod 11, and the outer side of the bearing can rotate around the first support rod 11, and the lower part of the first supporting platform 22 includes symmetrically arranged oblique rods, which are connected to the outer side of the bearing, so that the first supporting platform 22 can rotate around the first support rod 11; on the opening side O and the stop side S, the walking frame 1 is also provided with two limit rods at the bottom of the first supporting platform 22, and the limit rods are used to limit the rotation angle of the first supporting platform 22 to avoid excessive rotation angle affecting the loading and unloading of the actual parts box. The empty container unloading platform 3 is also provided with a second supporting platform 32, which has a structure similar to that of the cargo container loading platform 2. The top surface of the second supporting platform 32 in the empty container unloading platform 3 is installed with an unloading track 31, and the bottom thereof is provided with a rod of the traveling frame 1, wherein a second support rod 12 is provided at the center line of the second supporting platform 32. The second support rod 12 and the second supporting platform 32 are connected by a bearing so that the second supporting platform 32 can rotate around the second support rod 12; on the opening side O and the stop side S, the traveling frame 1 is further provided with two limit rods at the bottom of the second supporting platform 32, and the limit rods are used to limit the rotation angle of the second supporting platform 32 to prevent its rotation angle from being too large and affecting the unloading and loading of the empty parts box.

[0042] With this arrangement, when the quick exchange trolley 100 exchanges component boxes with the shelf, the empty box unloading platform 3 on the opening side O of the quick exchange trolley 100 can be tilted downward to facilitate the empty component box to slide toward the shelf under the action of gravity, and the empty component box can be unloaded by gravity; while the cargo box loading platform 2 can be tilted upward to facilitate the full component box to slide toward the stop side S under the action of gravity after entering the cargo box loading platform 2 from the shelf until the traveling frame 1 on the stop side S stops the full component box, thus completing the loading of the full component box by gravity. When the quick exchange trolley 100 moves to the production line to exchange component boxes, the empty box unloading platform 3 on the opening side O is tilted upward to facilitate receiving the empty component box from the production line, while the cargo box loading platform 2 is tilted downward to facilitate the full component box to slide from the cargo box loading platform 2 to the production line. In this way, the operator does not need to push the parts box with hands or tools to complete the parts box exchange operation. The operator only needs to rotate the cargo box loading platform 2 and the empty box unloading platform 3 to rely on gravity to complete the parts box exchange, which greatly reduces the operator's work intensity and further ensures the operator's safety.

[0043] Furthermore, in one embodiment of the present invention, the first support 22 and the second support 32 are respectively provided with counterweights on the stop side S, and the counterweights make the heights of the cargo box loading platform 2 and the empty box unloading platform 3 decrease from the opening side O to the stop side S. Figure 1 In order to ensure that the empty parts boxes and the full parts boxes can be as close as possible to the stop side S of the quick exchange trolley 100 when loaded on the quick exchange trolley 100, counterweights are installed on the side of the first support 22 and the second support 32 located on the stop side S, so that the parts of the cargo box loading platform 2 and the empty box unloading platform 3 located on the stop side S are weighted. This ensures that during the transportation of the parts boxes, the cargo box loading platform 2 and the empty box unloading platform 3 always remain tilted, with the tilting direction being from the opening side O to the stop side S, and the heights of the two platforms decreasing from the opening side O to the stop side S. Through this arrangement, the parts boxes are always close to the stop side S and away from the opening side O during transportation. Since the heights of the cargo box loading platform 2 and the empty box unloading platform 3 on the stop side S are lower than those on the opening side O, the parts boxes are not likely to fall during transportation, thereby improving the safety of the parts boxes during transportation and preventing them from falling and being damaged.

[0044] In one embodiment of the present invention, at the opening side O, the first support platform 22 is installed with a push rod assembly 221, and the second support platform 32 is installed with a pull rod assembly 321. The push rod assembly 221 is slidably connected to the shelf so that the first support platform 22 is pushed up at the opening side O, and the pull rod assembly 321 is slidably connected to the shelf so that the second support platform 32 is pulled down at the opening side O. For details, please refer to Figure 1 and Figure 5The push rod assembly 221 and the pull rod assembly 321 are provided on the quick exchange trolley 100. The push rod assembly 221 and the pull rod assembly 321 are both provided on the opening side O of the quick exchange trolley 100. The push rod assembly 221 is installed on the first supporting platform 22. When the quick exchange trolley 100 exchanges parts boxes with the shelf, the push rod assembly 221 is used to push up the cargo box loading platform 2, so that the cargo box loading platform 2 tilts from the opening side O to the stop side S, thereby facilitating the receipt of the real parts box from the shelf; a push rod slide is provided at the corresponding position of the real box platform of the shelf. In the process of moving the quick exchange trolley 100 to one side of the shelf, the push rod assembly 221 is slidably connected to the push rod slide, and the push rod slide applies a thrust to the push rod assembly 221, so that the push rod assembly 221 can drive the cargo box loading platform 2 to tilt from the opening side O to the stop side S, so that the real parts box slides to the stop side S under the action of gravity. The pull rod assembly 321 is installed on the second supporting platform 32. When the quick exchange trolley 100 exchanges parts boxes with the shelf, the pull rod assembly 321 is used to pull down the empty box unloading platform 3 on the opening side O, so that the empty box unloading platform 3 tilts from the stop side S to the opening side O. At this time, the height of the empty box unloading platform 3 on the stop side S is higher than the height on the opening side O, so that the empty parts box slides toward the empty box platform of the shelf under the action of gravity to complete the unloading of the empty parts box; a pull rod slide is provided at the corresponding position of the empty box platform of the shelf. In the process of moving the quick exchange trolley 100 to one side of the shelf, the pull rod assembly 321 is slidably connected to the pull rod slide, and the pull rod slide applies a pulling force to the pull rod assembly 321, so that the pull rod assembly 321 can drive the empty box unloading platform 3 to tilt from the stop side S to the opening side O.

[0045] This arrangement allows the quick exchange trolley 100 to automatically exchange parts boxes with the shelf under the action of gravity. Full parts boxes automatically slide to the stop side S under the action of the tilted container loading platform 2 and its own gravity, while empty parts boxes automatically slide to the open side O and enter the shelf under the action of the tilted empty container unloading platform 3 and its own gravity. This eliminates the need for operators to actively adjust the tilt of the container loading platform 2 and the empty container unloading platform 3. The quick exchange trolley 100 only needs to be moved to the corresponding position on the shelf to automatically exchange empty and full parts boxes. This improves the efficiency of part box exchange, reduces operator labor, and saves labor costs.

[0046] Further, see Figure 1 and Figure 5In one embodiment of the present invention, the push rod assembly 221 includes a first pulley 2211 and a first connecting arm 2212. The first pulley 2211 is rotatably connected to one end of the first connecting arm 2212, and the other end of the first connecting arm 2212 is mounted on the first supporting platform 22. The pull rod assembly 321 includes a second pulley 3211 and a second connecting arm 3212. The second pulley 3211 is rotatably connected to one end of the second connecting arm 3212, and the other end of the second connecting arm 3212 is mounted on the second supporting platform 32. Specifically, the first connecting arm 2212 of the push rod assembly 221 is generally L-shaped, including a long arm and a short arm. The first pulley 2211 is connected to the short arm and can rotate around the short arm. The long arm portion is connected to the rod member on the first supporting platform 22. When the quick exchange trolley 100 exchanges parts boxes with the shelf, the first pulley 2211 slides along the push rod slide, causing the cargo box loading platform 2 to remain tilted from the opening side O to the stop side S. After the first pulley 2211 slides off the push rod slide, the gravity of the parts box and the counterweight on the stop side S causes the cargo box loading platform 2 to remain tilted from the opening side O to the stop side S. The overall structure of the pull rod assembly 321 is similar to that of the push rod assembly 221. The second pulley 3211 is rotatably mounted on the short arm of the second connecting arm 3212. The long arm portion of the second connecting arm 3212 is connected to the rod on the second support platform 32. When the quick exchange trolley 100 exchanges parts boxes with the shelf, the second pulley 3211 slides along the pull rod slide, so that the empty box unloading platform 3 remains tilted from the stop side S to the opening side O. The empty parts box can slide from the empty box unloading platform 3 to the shelf. When the second pulley 3211 slides out of the pull rod slide, the gravity of the counterweight on the stop side S causes the tilt direction of the empty box loading platform to change from the opening side O to the stop side S. This arrangement makes it easier for the push rod assembly 221 and the pull rod assembly 321 to connect with the push rod slide and the pull rod slide on the shelf, thereby facilitating the docking of the quick exchange trolley 100 with the shelf.

[0047] In one embodiment of the present invention, the rapid exchange trolley 100 further includes a buffer 4, which is mounted on the stopper side S of the traveling frame 1 to prevent the parts box from hitting the traveling frame 1. Figure 1 and Figure 2 A buffer 4 is installed on the stop side S of the traveling frame 1. The number of buffers 4 can be set to one or more according to actual needs. The buffer 4 includes at least one of an elastic rubber buffer, a polyester-ammonia buffer, and even a vacuum suction cup. The main purpose is to use the elasticity of the buffer 4 to block and buffer the parts box, thereby preventing the parts box from directly hitting the traveling frame 1 on the stop side S when loading, thereby avoiding damage to the traveling frame 1 or the parts box.

[0048] In one embodiment of the present invention, the rapid exchange trolley 100 further includes a plurality of guide rails 5, which are respectively mounted on the traveling frame 1 on both sides of the cargo box loading platform 2 and the empty box unloading platform 3. Figure 1 and Figure 2 Facing the opening side O, brackets for the traveling frame 1 are provided on both sides of the cargo box loading platform 2 and the empty box unloading platform 3, each higher than the two platforms. These brackets are connected to the brackets on the stop side S and are used to prevent the component boxes from falling during transportation. Guide rails 5 are installed on both brackets. The guide rails 5 have a smooth surface and, in this embodiment, are arranged perpendicular to the plane of the stop side S. This facilitates the sliding of the component boxes and prevents them from getting stuck in the gaps of the traveling frame 1 during loading or unloading. This ensures that the quick exchange trolley 100 and the shelf can smoothly exchange component boxes, thereby ensuring work efficiency.

[0049] See also Figure 1 and Figure 2In one embodiment of the present invention, the rapid exchange trolley 100 further includes a lever assembly 6, which is rotatably mounted on the traveling frame 1 on the opening side O. The lever assembly 6 includes an open state and a closed state. When the rapid exchange trolley 100 moves to one side of the shelf, the rod on the shelf drives the lever assembly 6 to rotate and enter the open state, so that the shelf and the rapid exchange trolley 100 can exchange parts boxes. When the rapid exchange trolley 100 moves away from the shelf, the lever assembly 6 enters the closed state to prevent the parts boxes from falling from the rapid exchange trolley 100. The number of the lever assemblies 6 is at least two. On the opening side O of the rapid exchange trolley 100, at least one lever assembly 6 is mounted on the traveling frame 1 on both sides of the cargo box loading platform 2. At the same time, at least one lever assembly 6 is also mounted on the traveling frame 1 on both sides of the empty box unloading platform 3. In this embodiment, two lever assemblies 6 are mounted on both sides of the cargo box loading platform 2 and the empty box unloading platform 3. A parts box placement space is formed between the traveling frame 1 and the empty box unloading platform 3 and the cargo box loading platform 2. The gear lever assembly 6 includes a gear lever, a bearing, a limit block and a push plate. The bearing is rotatably mounted on the traveling frame 1. One end of the gear lever is mounted on the outer wall of the bearing, and the other end points to the parts box placement space. The limit block is mounted on the traveling frame 1 and is located at the lower part of the gear lever to support the gear lever. A push plate is mounted on the lower side of the bearing. By pushing the push plate, the gear lever can be rotated upward around the bearing. When no external force is applied to the push plate, the gear lever will fall down and eventually stop on the limit block because the weight of the gear lever is greater than the weight of the push plate. When the quick exchange trolley 100 is located away from the shelf, the shift lever assembly 6 is in a closed state, the shift lever is in contact with the limit block, and the shift lever now points to the component box placement space, which is used to prevent the component box from sliding off the empty box unloading platform 3 or the cargo box loading platform 2; when the quick exchange trolley 100 and the shelf are exchanging component boxes, the rod member provided on the corresponding shift lever component on the shelf can push the push plate, thereby driving the shift lever to rotate upward around the bearing, so that the component box exchange operation is not blocked by the shift lever.

[0050] To facilitate the sliding of the parts box, in one embodiment, there are at least two loading rails 21 and at least two unloading rails 31, and at least two loading rails 21 are arranged parallel to each other, and at least two unloading rails 31 are arranged parallel to each other. There are at least two loading rails 21 and at least two unloading rails 31, and preferably three or more. In this embodiment, there are four loading rails 21 and at least four unloading rails 31, and the four loading rails 21 are arranged parallel to each other, and the four unloading rails 31 are also arranged parallel to each other. This allows the full and empty parts boxes to slide more easily under their own weight when loading or unloading full parts boxes, facilitating the exchange of parts boxes.

[0051] Furthermore, the loading track 21 includes a first guide groove 211 and a plurality of first rollers 212. The first guide groove 211 is mounted on the top surface of the first support 22 and extends from the opening side O to the stop side S. The plurality of first rollers 212 are placed in the first guide groove 211 and are rotatably connected to the inner wall of the first guide groove 211. The unloading track 31 includes a second guide groove 311 and a plurality of second rollers 312. The second guide groove 311 is mounted on the top surface of the second support 32 and extends from the opening side O to the stop side S. The plurality of second rollers 312 are placed in the second guide groove 311 and are rotatably connected to the inner wall of the second guide groove 311. For details, please refer to Figure 1 The first guide groove 211 of the loading rail 21 is installed on the top surface of the first supporting platform 22. The first guide groove 211 is arranged perpendicular to the opening side O and the stop side S of the traveling frame 1, and the first guide groove 211 extends from the opening side O to the stop side S. The cross-section of the first guide groove 211 is "concave". On the inner wall of the first guide groove 211, multiple first rollers 212 are installed in parallel, so that the real parts box can slide from the opening side O to the stop side S along the direction of the first guide groove 211. The second guide groove 311 of the unloading track 31 is mounted on the top surface of the second support platform 32. The second guide groove 311 is perpendicular to the opening side O and the stop side S of the traveling frame 1, extending from the opening side O to the stop side S. The second guide groove 311 has a concave cross-section. Multiple second rollers 312 are mounted parallel to the inner wall of the second guide groove 311, allowing empty parts boxes to slide along the second guide groove 311 from the stop side S to the opening side O and onto the shelf. This arrangement further improves the sliding smoothness of the parts boxes on the rapid exchange trolley 100, expediting the exchange of parts boxes.
