Description

Technical Field

[0001] This application relates to the field of logistics transmission equipment technology, and more specifically, to a flexible traction guide device and a logistics transmission system. Background Technology

[0002] In devices that utilize flexible traction materials such as steel wire ropes for traction, one or more guide wheel structures, such as pulleys with flanges or idler gears, are typically used to guide the flexible traction material. When there are connecting objects on the flexible traction material, various technical measures must be taken to ensure that the guide wheels avoid the connecting objects, such as creating notches in the guide wheels. (See [reference needed]). Figure 1 This is to prevent the connecting object from hitting the guide wheel, or the wire rope from going out of the groove, the timing pulley from skipping teeth, the chain link from getting stuck, and other malfunctions.

[0003] When the length of the flexible traction object increases and the spacing between the force-bearing components is unequal, it becomes very difficult to implement smooth guidance, and there is currently no suitable technical solution.

[0004] Therefore, it is necessary to provide a wire rope guiding device that can be applied to multiple scenarios and enable the traction device to have a long service life. Summary of the Invention

[0009] A driving device is used to drive the guide structure to move according to a speed signal and a time signal when the force-bearing member moves to the vicinity of the guide structure with the flexible traction object, so that the notch on the guide structure actively meets the force-bearing member;

[0010] After the force-bearing component is fitted into the notch, the guide structure is driven by the driving device; the notch on the guide structure causes the force-bearing component to rotate.

[0011] In one embodiment, the guide structure includes:

[0014] Multiple first guide wheels within a predetermined arc area guide the flexible traction object; the gap between two first guide wheels at a predetermined position on the outer circumference of the guide body constitutes the notch.

[0015] In one embodiment, the meshing structure on the outer circumferential surface of the first guide wheel is a first tooth structure that meshes with the timing belt teeth, a second tooth structure that meshes with the chain gap, or a groove that can accommodate the cable.

[0020] The first controller is communicatively connected to the first displacement sensor, the first angle sensor, and the driving device, respectively. It is used to determine the angle that the guide body needs to rotate based on the distance between the force-bearing component and the guide body and the position of the notch on the guide body, and to determine the speed signal and time signal of the guide body rotation based on the moving speed of the force-bearing component and send them to the driving device.

[0021] The driving device controls the rotation of the guide body according to the speed signal and the time signal, so that the force-bearing component engages with the notch.

[0025] The first second guide wheel located on the arc-shaped guide track can actively meet the force-bearing component under the drive of the drive device, and the other second guide wheels in the arc-shaped guide track have the same rotation angle as the first second guide wheel.

[0028] The second drive is disposed on the first second guide wheel of the arc-shaped guide track;

[0029] A double-row synchronous pulley or sprocket is used to drive the adjacent second guide pulleys so that the other second guide pulleys in the arc-shaped guide trajectory follow the first second guide pulley.

[0030] In one embodiment, a self-rotating meshing structure is provided on the outer circumferential surface of the second guide wheel.

[0034] The second controller is communicatively connected to the second displacement sensor, the second angle sensor, and the drive device, respectively. It is used to determine the required rotation angle of the first second guide wheel based on the distance between the force-bearing component and the first second guide wheel and the position of the notch in the first second guide wheel, and to determine the speed signal and time signal of the rotation of the first second guide wheel based on the moving speed of the force-bearing component, and to send the speed signal and time signal to the drive device.

[0035] The driving device controls the rotation of the first second guide wheel according to the speed signal and the time signal, so that the force-bearing component engages with the notch of the second guide wheel.

[0036] In one embodiment, after the force-bearing member is fitted into the notch, the guide structure is driven by the driving device; the notch on the guide structure causes the force-bearing member to rotate.

[0037] According to another aspect of this application, a logistics transport system is also provided, including a flexible traction element arranged with one or more force-bearing elements and a flexible traction element guiding device as described in any of the preceding claims.

[0038] As can be seen from the above technical solutions, the flexible traction guide device in this application is provided with a notch that can engage with the force-bearing components on the flexible traction object, and the notch is used to actively meet the force-bearing components, rather than waiting to engage with the force-bearing components at a designated position. Since the position of the notch is no longer limited by the position and spacing of the force-bearing components, this application can be applied to more complex guiding scenarios.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0046] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0047] The traditional guiding method for wire rope guide wheels involves the connector on the wire rope moving to the traction notch and then fitting into it. The connector then drives the guide wheel to rotate. After the connector has rotated the guide wheel by a predetermined angle, it disengages from the notch, and subsequent connectors continue to drive the guide wheel. This method restricts the diameter of the wire rope guide wheel and the position of the notch to the spacing of the connectors on the wire rope. The inventors of this application creatively propose that the curved section of the guide wheel used for guiding is no longer driven by the connectors but is solely used to guide the wire rope. A notch is provided to accommodate the connector. An additional drive device is installed on the guide wheel, causing it to rotate so that the notch actively aligns with the connector approaching the curved section. After the connector fits into the notch, the drive wheel rotates, changing the position of the notch until the connector on the wire rope disengages from the notch. Because it can actively accommodate the connected objects, the guiding method in this application makes the diameter of the wire rope guide wheel and the setting of the notch position no longer limited by the spacing of the connected objects on the wire rope, thus making it applicable to more scenarios.

[0048] The guiding device and its working principle described above will be explained in detail below through specific embodiments.

[0049] Figure 2 This is an example of a flexible traction guide device according to an embodiment of this application. See also... Figure 2 The flexible traction guide device includes a flexible traction object 100, a guide structure 200, and a drive device (not shown in the figure).

[0050] Conveying equipment is generally classified into conveying equipment with flexible traction and conveying equipment without flexible traction based on whether it has traction (chain, rope, belt). The flexible traction elements described in this application include, but are not limited to, synchronous belts, chains, and structures with protruding connecting parts. Figure 2 The structure of the flexible traction guide device is described in the embodiment shown, taking a steel wire rope with a protruding connector as an example.

[0051] One or more force-bearing members 300 are arranged on the flexible traction object 100. A guide structure 200 is used to surround and guide the flexible traction object 100. A notch 210 is provided on the guide structure 200 to engage with the force-bearing member 300. A drive device is used to drive the guide structure 200 to rotate. When the force-bearing member 300 moves with the flexible traction object 100 to the vicinity of the guide structure 200, the drive device drives the guide structure 200 to actuate so that the notch 210 on the guide structure 200 actively engages with the force-bearing member 300. After the force-bearing member 300 engages with the notch 210, the drive device drives the guide structure 200 to rotate with the flexible traction object 100.

[0052] In one implementation, Figure 3 for Figure 2 Partial schematic diagram of the AA-direction section. See also Figure 3 The guide structure 200 includes a guide body 220 and a predetermined number of first guide wheels 230.

[0053] The guide body 220 can rotate under the drive of the drive device. The drive device can be installed on the guide body 220 or located outside the guide body 220. This application does not specifically limit the position of either, as long as the drive device can drive the guide body 220 to rotate.

[0054] Each first guide wheel 230 is rotatable, and a predetermined number of first guide wheels 230 are circumferentially arranged on the entire outer circumferential surface of the guide body 220 to form a guide arc. The diameter of each first guide wheel 230 is smaller than the diameter of the guide body 220, and the axis of each first guide wheel 230 is parallel to the axis of the guide body 220. Each first guide wheel 230 has an engagement structure on its outer circumferential surface that can engage with the flexible traction object 100.

[0055] The meshing structure on the outer circumferential surface of the first guide wheel 230 varies depending on the type of flexible traction device 100. For example, when the flexible traction device 100 is a steel wire rope with a protruding connector, the meshing structure on the outer circumferential surface of the first guide wheel 230 is a groove that can accommodate the steel wire rope, see [reference needed]. Figure 3When the flexible traction object 100 is a synchronous belt, the meshing structure on the outer circumferential surface of the first guide wheel 230 is a first tooth structure capable of meshing with the teeth on the synchronous belt. When the flexible traction object 100 is a chain, the meshing structure on the outer circumferential surface of the first guide wheel 230 is a second tooth structure capable of meshing with the chain gap. It should be noted that this application does not specifically limit the meshing structure on the outer circumferential surface of the first guide wheel 230; its structure is adaptively adjusted according to the structure of the flexible traction object 100. After the flexible traction object 100 meshes with the meshing structure on the outer circumferential surface of the first guide wheel 230, the first guide wheel 230 functions only as an idler wheel; the first guide wheel 230 can rotate on its own and does not provide traction for the flexible traction object 100.

[0056] Multiple first guide wheels 230 within a predetermined arc area guide the flexible traction object 100. A notch 210 is formed by the gap between two first guide wheels 230 at a predetermined position on the outer circumference of the guide body 220. It should be noted that when there is only one notch 210 on the guide body 220, it is sufficient to create a gap between two first guide wheels 230 on the guide body 220. The gap between the two first guide wheels 230 is determined according to the shape of the force-bearing member 300 on the flexible traction object 100, and the size of the gap is sufficient to accommodate the force-bearing member 300 so that the flexible traction object 100 can pass smoothly through the guide body 220.

[0057] To ensure that the notch 210 on the guide body 220 actively engages with the force-receiving member 300 and that the force-receiving member 300 fits precisely within the notch 210 of the guide body 220, in one embodiment, a first displacement sensor is positioned at a predetermined location in front of the guide body 220. The first displacement sensor is used to acquire the distance between the force-receiving member 300 and the guide body 220. A first angle sensor is also provided on the guide body 220 to acquire the position of the notch 210 on the guide body 220. Simultaneously, the flexible traction device 100 also includes a first controller communicatively connected to the first displacement sensor, the first angle sensor, and the drive device. The first controller determines the required rotation angle of the guide body 220 based on the distance between the force-receiving member 300 and the guide body 220 and the position of the notch 210 on the guide body 220, as well as the moving speed of the force-receiving member 300 obtained from the previous controller. It then determines the speed and time signals of the guide body 220's rotation and sends them to the drive device. The drive device controls the guide body 220 to rotate according to the speed signal and the time signal, so that the force-bearing component 300 engages with the notch 210.

[0058] In another implementation, Figure 4 This is a schematic diagram illustrating another guiding structure according to an embodiment of this application. See also... Figure 4The guide structure 200 includes a second drive 260, a plurality of second guide wheels 240 and a double row of synchronous pulleys 250.

[0059] Each second guide wheel 240 has an engagement structure on its outer circumferential surface that can engage with the flexible traction object 100 and rotate on its own. In this embodiment, the engagement structure on the outer circumferential surface of the second guide wheel 240 can refer to the engagement structure on the outer circumferential surface of the first guide wheel 230; that is, the engagement structure varies depending on the type of flexible traction object 100. For example, when the flexible traction object 100 is a steel wire rope with a protruding connector, the engagement structure on the outer circumferential surface of the second guide wheel 240 is a groove for accommodating the steel wire rope, which can be referred to... Figure 5 The second guide wheel 240 has rollers 241 arranged in an array around its axis at a position away from the axis. The length of the rollers 241 is parallel to the axis of the second guide wheel 240, and the distance of the rollers 241 from the axis is less than the radius of the second guide wheel 240. Therefore, the rollers 241 form grooves that can accommodate steel wire ropes. The steel wire rope is wound around the rollers 241, and the rollers 241 can rotate. When the flexible traction object 100 is a synchronous belt, the meshing structure on the outer circumferential surface of the second guide wheel 240 is a first tooth structure that can mesh with the teeth on the synchronous belt. When the flexible traction object 100 is a chain, the meshing structure on the outer circumferential surface of the second guide wheel 240 is a second tooth structure that meshes with the chain gaps.

[0060] Several second guide wheels 240 are configured to form an arc-shaped guide trajectory. Each second guide wheel 240 has a notch 210. A second driver 260 is disposed on the first second guide wheel 240 of the arc-shaped guide trajectory. The second driver 260 and the first second guide wheel 240 can be driven by a synchronous belt pulley or by a sprocket. This application does not specifically limit the transmission structure between the second driver 260 and the first second guide wheel 240. Any structure that enables the second driver 260 to drive the first second guide wheel 240 to rotate falls within the protection scope of this application.

[0061] The double-row synchronous pulley 250 is used to connect adjacent second guide pulleys 240 and to set the orientation of the notches 210 on adjacent second guide pulleys 240 to be misaligned. The misalignment angle of the notches 210 on adjacent second guide pulleys 240 is configured such that after the force-bearing member 300 on the flexible traction member 100 leaves the notch 210 of the previous second guide pulley 240 at a predetermined speed, it just enters the notch 210 of the next second guide pulley 240.

[0062] In one implementation, the spacing between the plurality of second guide wheels 240 can be set to be very small, such that each second guide wheel 240 is not interfered with by adjacent second guide wheels 240. Driven by a double-row synchronous belt pulley 250, the plurality of second guide wheels 240 rotate at the same speed. When the notches 210 on the plurality of second guide wheels 240 are mapped onto a single guide wheel, the notches 210 on the second guide wheels 240 are arranged adjacently on a circumference and exactly form a circumference.

[0063] It should be noted that the use of a double-row synchronous belt is merely exemplary, and a sprocket structure can also be used as a substitute. This application does not specifically limit the transmission structure between the second guide wheels 240; any transmission structure that enables several second guide wheels 240 to rotate simultaneously falls within the protection scope of this application.

[0064] It should be noted that the above-described drive device that uses the second driver 260 and the double-row synchronous pulleys 250 / sprockets to make all the second guide wheels 240 rotate simultaneously is only an example. The drive device may also include a first driver disposed on each of the second guide wheels. The drive device can achieve the simultaneous rotation of all the second guide wheels by controlling each first driver.

[0065] To ensure that the notch 210 of the second guide wheel 240 in the first position can actively meet the force-receiving member 300 and that the force-receiving member 300 is precisely fitted into the notch 210 of the guide body 220, in one embodiment, a second displacement sensor is provided at a predetermined position. The second displacement sensor is used to detect the distance between the force-receiving member 300 and the first second guide wheel 240 on the arc-shaped guide track entry side. It should be noted that this application does not specifically limit the location of the second displacement sensor; any location capable of detecting the distance between the force-receiving member 300 and the first second guide wheel 240 on the arc-shaped guide track entry side falls within the protection scope of this application. A second angle sensor is provided on the first second guide wheel 240. The second angle sensor is used to obtain the position of the notch 210 of the first second guide wheel 240 when the force-receiving member 300 reaches the predetermined position. Simultaneously, the flexible traction object 100 guide device is also provided with a second controller. The second controller is communicatively connected to the second displacement sensor, the second angle sensor, and the second driver 260, respectively. It determines the required rotation angle of the first second guide wheel 240 based on the distance between the force-bearing component 300 and the first second guide wheel 240 and the position of the notch 210 in the first second guide wheel 240. It also determines the speed and time signals of the rotation of the first second guide wheel 240 based on the moving speed of the force-bearing component 300, and sends these signals to the second driver 260. The second driver 260 controls the rotation of the first second guide wheel 240 according to the speed and time signals, so that the force-bearing component 300 engages with the notch 210 of the second guide wheel 240.

[0066] The above-described structure of adjacent second guide wheels 240 is merely exemplary. Adjacent second guide wheels 240 may also be spaced apart by a certain gap. Correspondingly, the gap 210 between adjacent second guide wheels 240, in addition to the offset angle, will also have an additional arc length, which depends on the distance between adjacent second guide wheels 240 and the radius of the second guide wheels 240. In this embodiment, a second displacement sensor can be used to detect the distance between the force-bearing member 300 and the first second guide wheel 240 on the arc-shaped guide trajectory entry side. Based on the distance between adjacent second guide wheels 240 and the moving speed of the flexible traction object 100, the position of the gap 210 of the next second guide wheel 240 should be calculated, so that the force-bearing member 300 fits precisely into the gap 210 of the second guide wheel 240 when it reaches the gap 210 of the next second guide wheel 240.

[0067] In one embodiment, after the force-bearing member is fitted into the notch, the guide structure is driven by the driving device; the notch on the guide structure causes the force-bearing member to rotate.

[0068] In this embodiment, after the force-bearing component is engaged with the notch, the guide structure can either serve only a guiding function or be driven by the driving device, thus achieving both guiding and driving functions. When only guiding is performed, after the notch engages the force-bearing component, the driving device stops driving, and the guide wheel enters an idler state. When serving both guiding and driving functions, after the notch engages the force-bearing component, the driving device continues to rotate the notch, the guide wheel enters a driving state, and the force-bearing component is pushed by the notch to move along the circumferential edge.

[0069] As can be seen from the above technical solutions, the flexible traction guide device in this application is provided with a notch 210 that can engage with the force-bearing member provided on the flexible traction object 100, and the notch 210 is used to actively meet the force-bearing member 300, rather than waiting to engage with the force-bearing member at a designated position. Since the position of the notch 210 is no longer limited by the position and spacing of the force-bearing member 300, this application can be applied to more complex guiding scenarios.

[0070] According to a second aspect of this application, a logistics transport system is also provided, including a flexible traction element 100 with one or more force-bearing elements 300 arranged thereon and a flexible traction element guide device as described above.

[0071] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0072] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0073] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
