Description

Technical Field

[0001] This utility model relates to the field of transportation device technology, specifically to a trigger switch and its transportation trolley, and a multi-layer sorting machine. Background Technology

[0002] Multi-layer sorting machines are commonly used sorting devices in logistics, manufacturing, and other fields. They mainly consist of multiple stacked transport channels and corresponding lifting and sorting devices. For example, patent application number 202021561087.7 ​​discloses a sorting machine including multiple independent sorting conveyors. Each layer of the sorting conveyor is equipped with a reciprocating trolley that can move back and forth along its length. Multiple independent exit conveyors are located outside the sorting machine, with each layer of sorting conveyors corresponding to one of the multiple layers of exit conveyors. Each layer of sorting conveyor has multiple compartments on its side along its length. The reciprocating trolley of each layer of sorting conveyor can connect with the exit conveyor and the goods in the compartments of the same layer.

[0003] However, the continuous elevator used in this patent lacks guardrails or similar structures to protect materials during the lifting process. Furthermore, since the elevator trolley needs to connect with the sorting channel during material sorting, the guardrails must also be able to lower after the elevator trolley moves to the appropriate position to avoid obstructing material transport. Therefore, the elevator trolley must first be equipped with corresponding switches or other structures to control the raising and lowering of the guardrails. Utility Model Content

[0004] The technical problem this invention aims to solve is to provide a trigger switch that can switch its state through interaction with external components. When the trigger switch is installed in equipment such as a lifting trolley, it can cause the trigger switch to contact the external component when the lifting trolley reaches a designated position, resulting in the trigger switch entering a closed state and changing the state of the guardrail in the lifting trolley; and when the lifting trolley moves away from the designated position and separates from the external component, the trigger switch returns to the open state, and the guardrail in the trolley is restored, thereby making the guardrail adaptable to the working needs of the lifting trolley.

[0005] This utility model is achieved through the following technical solution:

[0006] A trigger switch, characterized in that it comprises: a main body, a trigger rod, a drive collar, a response rod, and a connecting part; the trigger rod is mounted on the main body via a movable connector, the trigger rod is rotatable around the movable connector, the movable connector divides the trigger rod into a trigger part and a response part, a return component is connected between the trigger rod and the main body, and the drive collar is sleeved on the response part; one end of the response rod is movably connected to the drive collar, and the other end is provided with a connecting section; the main body is also provided with a guide part for restricting and guiding the response rod to move in the vertical direction; the connecting part includes two sets of connecting blocks, a first gap is formed between the two sets of connecting blocks for accommodating the connecting section; when the trigger rod rotates and drives the response rod to rise and fall through the drive collar until the connecting section contacts the connecting block, the trigger switch closes, and the external circuit is connected.

[0007] As a further improvement of this utility model, the guide portion includes a set of guide clamps, and the response rod is embedded between the guide clamps.

[0008] As a further improvement of this utility model, the ends of the two sets of connecting blocks that are away from the location of the connecting segment are connected by a connecting block.

[0009] Secondly, this utility model provides a transport trolley for receiving and transferring goods, comprising: a trolley body, a guardrail movably mounted on at least one side of the trolley body, at least one set of drive kits for driving the guardrail to move, a reset kit connected to the guardrail, and any one of the above-mentioned trigger switches; wherein the trigger switch is placed in the circuit of the movable extension kit and is used to control the start and stop of the drive kit.

[0010] As a further improvement of this utility model, the guardrail is installed on the trolley body via a rotating connector, and the drive kit includes a movable extension kit, one end of which forms a drive section for driving the guardrail to rotate.

[0011] As a further improvement of this utility model, a rotation limit block is provided on the trolley body or the guardrail to limit the lower limit of the rotation of the guardrail.

[0012] As a further improvement of this utility model, the guardrail is provided with a guide surface structure. When the guardrail is rotated to the flat guiding state, the guide surface structure is used to guide the material to be transferred to the transport surface of the trolley body.

[0013] As a further improvement of this utility model, the reset kit includes two hydraulic rods respectively disposed on both sides of the guardrail. One end of the hydraulic rod is movably connected to the guardrail, and the other end is movably connected to the trolley body.

[0014] Thirdly, this utility model provides a multi-layer sorting machine, which includes several layers of transmission channels and at least one sorting and lifting device. In the sorting and lifting device, any of the above-mentioned transport trolleys are used to support the materials, and the lifting and lowering of the transport trolleys is controlled by the lifting system.

[0015] As a further improvement of this utility model, a transmission inlet is provided on the transmission channel for receiving the material carried by the transport trolley; an extended starting block is installed on one end of the transmission inlet near the sorting and lifting device for contacting the triggering part.

[0016] The beneficial effect of this utility model is that when the trigger switch is affected by external force, it can enter the closed state by adjusting the component structure such as the rotation of the trigger rod; and after the influence of the external force disappears, the trigger switch returns to the open state by the return component, which meets the requirement that some circuits and their connected devices need to be triggered and started under specific conditions, and the triggering conditions are realized through physical structure, which is more reliable.

[0017] Taking the circuit of the drive assembly on the transport trolley as an example, after the transport trolley moves to the corresponding position, the external protrusions abut against the triggering part, causing the trigger rod to rotate in any direction and ultimately move the response rod. The connecting section then contacts the connecting block, causing the trigger switch to close and activate the drive assembly, prompting the guardrail to move, thus facilitating the transfer of materials on the transport trolley. When the transport trolley is in operation, the external protrusions no longer affect the triggering part, the repositioning component returns the trigger rod to its original position, and the trigger switch randomly switches to the open state, allowing the guardrail to return to its original position and resume its protective function. Through the trigger switch, the drive assembly and related guardrails in the transport trolley can respond and change according to the corresponding position to adapt to current needs.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0026] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0027] Example 1:

[0028] This embodiment provides a trigger switch, such as Figure 1 As shown, it mainly includes a main body A01, a trigger rod A02, a drive collar A03, a response rod A04, and a connecting part A05.

[0029] The trigger rod A02 is mounted on the main body A01 via a movable connector. After installation, the trigger rod A02 can rotate around the movable connector. The movable connector can be a pin connection, a threaded connection, etc. In this embodiment, a riveting connection is used, meaning the trigger rod A02 can rotate around the rivet used for fixing after installation. In the above structure, the trigger rod A02 is divided into two parts by the movable connector: a trigger part A02-1 and a response part A02-2. A return component A02-3 connects the trigger rod A02 and the main body A01. In this embodiment, the return component A02-3 is connected to the trigger part A02-1. A drive collar A03 is fitted onto the response part A02-2, and the drive collar A03 can slide along the response part A02-2. The return component A02-3 can be a spring, a hydraulic rod, etc.; in this embodiment, a spring is used.

[0030] The response rod A04 is linked to the trigger rod A02 via the drive collar A03. One end of the response rod A04 is movably connected to the drive collar A03, while the other end is fixedly connected to the connecting section A04-1. The movable connection between the response rod A04 and the drive collar A03 can be a pin connection, a threaded connection, or a hinge; in this embodiment, a hinge is used. Since the main body A01 also has a guide part A06 to restrict and guide the response rod A04 to move only in the vertical direction, under the above structure, when the trigger rod A02 rotates, it can only drive the response rod A04 and its connecting section A04-1 to move either upwards or downwards. The guide part A06 can adopt a kit of guide groove and guide block, two sets of clamping guide blocks, etc. In this embodiment, preferably, the guide part A06 includes a set of guide clamping blocks A06-1, and the response rod A04 is embedded between the guide clamping blocks A06-1, so that the response rod A04 can only slide relative to the guide clamping blocks A06-1 in the vertical direction.

[0031] The connecting part A05 mainly includes two sets of connecting blocks A05-1, with a first gap L1 between the two sets of connecting blocks A05-1 to accommodate the connecting segment A04-1. Therefore, when the connecting segment A04-1 is raised or lowered by a certain distance, it can come into contact with any of the connecting blocks A05-1. When the trigger switch provided in this embodiment is placed in the circuit, one end of the circuit is connected to the response rod A04 or the connecting segment A04-1, while the other end of the circuit is connected to the two connecting blocks A05-1 respectively. Therefore, when the connecting segment A04-1 comes into contact with any of the connecting blocks A05-1, the switch can be triggered to close completely, and the external circuit can be connected completely.

[0032] The specific working process of the trigger switch is as follows Figure 1 The following example illustrates the installation situation and the structural changes when state a in the diagram is changed to state b or c. When the trigger part A02-1 is not affected by any external force, it is in a horizontal state. At the same time, the connecting section A04-1 is also placed between the two sets of connecting blocks A05-1 without contacting them. Therefore, the trigger switch is in the open state and the external circuit is not connected.

[0033] When the trigger part A02-1 is affected by external force and is pressed down or lifted, the corresponding response part A02-2 will undergo the opposite state change, such as being lifted up or pressed down. However, no matter how the response part A02-2 changes, it will drive the response rod A04 and the connecting section A04-1 on it to rise or fall together through the drive collar A03. After the connecting section A04-1 rises or falls, it will contact the connecting block A05-1, thereby making the trigger switch closed and the external circuit connected.

[0034] When the external force is removed, the return component A02-3 will drive the trigger lever A02 to return to the horizontal state, that is, the trigger switch automatically returns to the open state. Therefore, the trigger switch can remain in the normally open state under normal circumstances.

[0035] Preferably, the ends of the two sets of connecting blocks A05-1 that are furthest from the location of the connecting segment A04-1 are connected by a connecting block A05-2. With this structure, one end of the external circuit only needs to be connected to any one of the connecting blocks A05-1 to achieve the connection of the external circuit when the trigger switch is closed, thus reducing the number of external interfaces required in the external circuit.

[0036] Example 2:

[0037] This embodiment provides a transport trolley, such as Figures 2-4 As shown, the transport trolley mainly includes a trolley body B01, a guardrail B02, a drive kit B03, a reset kit B04, and the trigger switch described in Embodiment 1, wherein the trigger switch is connected to the start circuit of the drive kit B03. If the trigger switch is closed, the drive kit is started and can provide driving force; if the trigger switch is open, the drive kit is turned off and stops providing driving force.

[0038] The transport trolley has at least one docking side, which is usually the main window for loading and unloading materials. Therefore, during loading and unloading, the guardrail B02 on this side needs to be moved to avoid obstructing the transport of materials. The guardrail B02 can be installed on the transport trolley through any connection method such as a rotating connector or a lifting connector, and the drive kit B03 is mainly used to drive the movement of the guardrail B02.

[0039] A trigger switch is installed in the circuit of the drive kit B03. When the transport trolley moves to the corresponding position, the trigger rod A02 of the trigger switch will be affected by external force and rotate, thereby causing the trigger switch to close, the drive kit B03 to be activated, and the guardrail B02 to move. After the material loading and unloading is completed and the transport trolley moves, the influence of external force disappears, and the trigger switch is driven by the return component A02-3 to open. In this embodiment, the return component A02-3 is connected to the response unit A02-2 and the main body A01. Subsequently, the drive device stops generating driving force. At this time, under the action of the reset kit B04, the guardrail B02 also returns to its original position to resume its protective function for the material. The reset kit B04 is connected to the guardrail B02 and can be an elastic component such as a spring or a hydraulic rod.

[0040] Preferably, the guardrail B02 is mounted on the trolley body B01 via a rotating connector, and the drive kit B03 mainly includes a movable extension kit B03-1, one end of which is formed with a drive section B03-1a for driving the guardrail B02 to rotate.

[0041] like Figures 2-3 As shown, when the trigger switch is closed, the movable extension kit B03-1 receives driving force and extends out of the trolley body B01. Its driving section B03-1a abuts against the guardrail B02, and as the extension amount of the movable extension kit B03-1 increases, it eventually drives the guardrail B02 to rotate until it lies flat. At this point, the guardrail B02 no longer obstructs the materials, and the transport trolley can smoothly carry out material loading and unloading operations. And as... Figure 4 As shown, when the trigger switch is in the off state, the movable extension kit B03-1 loses its driving force and the reset kit B04 begins to exert force, driving the guardrail B02 back to the vertical protective state. At this time, if there is material loaded on the trolley body B01, the guardrail B02 can protect the material to prevent it from falling. At the same time, if the material was originally partially placed outside the trolley body B01, the guardrail B02 will move the material during the lifting process until the entire material is placed on the trolley body B01, so as to protect the material from falling during the transfer of the transport trolley.

[0042] Preferably, a rotation limit block is provided on the trolley body B01 or the guardrail B02 to limit the lower limit of the guardrail B02's rotation. In this embodiment, the rotation limit block is provided on the guardrail B02. When the guardrail B02 rotates to the flat guiding state, the rotation limit block abuts against the trolley body B01, preventing the guardrail B02 from rotating and lowering further. At this time, the rotation limit block provides support for the guardrail B02, so that the guardrail B02 can play a connecting and supporting role during the transfer of materials to the trolley body B01, thereby preventing the materials from falling during the transfer process.

[0043] Preferably, the guardrail B02 is provided with a guide surface structure B02-1, such as... Figures 2-3 As shown, when the guardrail B02 is rotated to the flat guiding state, one end of the guiding surface structure B02-1 can connect with the transport surface of the trolley body B01, so as to guide the material to be smoothly transferred to the transport surface.

[0044] Preferably, such as Figures 2-4 As shown, the reset kit B04 includes two hydraulic rods B04-1 respectively disposed on both sides of the guardrail B02. One end of the hydraulic rod B04-1 is movably connected to the guardrail B02, and the other end is movably connected to the trolley body B01. The movable connection is to allow the hydraulic rod B04-1 to rotate relative to the guardrail B02 or the trolley body B01. It can be in the form of riveting, hinge, threaded connection, etc. In this embodiment, a riveting structure is used.

[0045] Example 3:

[0046] This embodiment provides a multi-layer sorting machine, such as Figure 5 As shown, the machine includes three-layer transport channels C01 and a sorting and lifting device C02. The sorting and lifting device C02 uses the transport trolley described in Example 2 to carry the materials, and the lifting system controls the raising and lowering of the transport trolley. This multi-layer sorting machine should be used in conjunction with an external transport channel. That is, the external transport channel transfers the materials to the transport trolley in the sorting and lifting device C02, and then the transport trolley is lifted. When the transport trolley is lifted to the corresponding height and aligned with the transport channel C01, the guardrail B02 is lowered to complete the transfer of the materials to the corresponding transport channel C01.

[0047] Therefore, triggering components A02-1 should be installed at corresponding heights on the multi-layer sorting machine and on the external conveying channel to drive the closing of the trigger switch and the transfer of the guardrail B02. Specifically, protrusions or similar structures can be installed at corresponding heights on the support rod of the sorting lifting device C02, or at the junction of the conveying channel C01 and the transport trolley, so that when the transport trolley is raised or lowered to the corresponding position, the protrusions contact the trigger rod A02, causing it to rotate, thereby closing the trigger switch and transferring the guardrail B02.

[0048] Preferably, each transmission channel C01 is provided with a transmission inlet for receiving materials carried by the transport trolley; an extended starting block is installed at one end of the transmission inlet near the sorting and lifting device C02 for contacting the trigger part A02-1.

[0049] like Figure 5 Taking the structure in the middle as an example, when the transport trolley moves to the middle layer of the transmission channel C01 and the material needs to be transferred, the extended start blocks on the upper and lower transmission channels C01 can remain in the retracted state, so that they will not come into contact with the trigger rod A02 when the transport trolley passes by.

[0050] The extended activating block on the middle layer transmission channel C01 remains extended. Therefore, as the transport trolley moves from top to bottom, the extended activating block first contacts the trigger rod A02, and as the transport trolley moves further down, it causes the trigger part A02-1 to rise. Until the transport trolley is aligned with the transmission inlet, the extended activating block remains in contact with the trigger rod A02, similar to... Figure 1 In the middle c state of the structure, the drive kit B03 can provide driving force to keep the guardrail B02 being transferred; finally, after the material is loaded, the transport trolley moves further down, and the trigger rod A02 gradually moves away from the extended starting block until the two no longer contact each other. The trigger switch returns to the normally open state, and the guardrail B02 returns to its position.

[0051] In multi-layer sorting machines, trigger switches enable the transfer of guardrail B02 by simply deploying external components, whether the transport trolley is being lifted or lowered. This means that the triggering methods of the trigger switches are more extensive, which in turn makes the deployment of transport trolleys and the design of flow routes more flexible.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
