Abstract
Description
Technical Field
[0001] This utility model relates to the field of AGV technology, specifically to a blocking device. Background Technology
[0002] Automated Guided Vehicles (AGVs) are transport vehicles equipped with electromagnetic or optical automatic guidance devices, capable of traveling along a prescribed guidance path, and possessing safety protection and various transfer functions.
[0003] In existing technology, AGVs move along tracks laid on the ground. This requires external devices to stop the AGV when it needs to come to a stop, preventing it from sliding on the track due to inertia and failing to stop at the preset position. Currently, the blocking mechanism is generally set on the ground near the track. When the AGV is transported to the preset position along the track, the blocking component on the blocking mechanism can move onto the track, thereby blocking the AGV and stopping it at the preset position.
[0004] However, existing blocking mechanisms do not have buffering force. When the AGV collides with the blocking component, the collision force is large and unstable, resulting in a lot of noise and the risk of materials falling off the AGV. At the same time, it is easy to damage the AGV and the blocking mechanism. Utility Model Content
[0005] In view of this, the present invention provides a blocking device to solve the problems that the existing blocking mechanism does not have a buffering force, resulting in a lot of noise generated by the collision between the AGV and the blocking component, and also poses a risk of materials falling off the AGV, while easily damaging the AGV and the blocking mechanism.
[0006] In a first aspect, this utility model provides a blocking device for blocking an AGV moving along a track, comprising:
[0007] A fixing component is installed on the ground on one side of the track;
[0008] A blocking assembly includes a mounting component, a blocking component, and a buffer component. The mounting component is connected to the drive end of the fixed assembly. One end of the buffer component is connected to the mounting component, and the other end of the buffer component is connected to the blocking component. The blocking component is adapted to contact the AGV.
[0009] The driving end of the fixed component is adapted to drive the blocking component to move above the track so that the blocking component corresponds to the AGV. When the blocking component collides with the AGV, the buffer is configured to buffer the movement of the AGV and decelerate the AGV to a stop.
[0010] Beneficial effects: By fixing the drive end of the component, the blocking component moves above the track and blocks the AGV. When the blocking component blocks the AGV, the buffer can buffer the movement of the AGV and decelerate the AGV, so that the AGV can slowly decelerate to a stop. The buffer reduces the collision force when the AGV collides with the blocking component and makes the collision between the blocking component and the AGV occur smoothly. This reduces the noise generated when the AGV collides with the blocking component and avoids the risk of materials falling off the AGV. At the same time, because the collision force between the AGV and the blocking component is reduced, the AGV and the blocking device are less likely to be damaged.
[0011] In one optional embodiment, the buffer is a buffer pressure device, the fixed end of which is connected to the mounting component, and the telescopic end of which is connected to the blocking component.
[0012] Beneficial effects: By setting the buffer component as a buffer pressure device, which is a conventional instrument, it will not be described in detail in this embodiment. When the buffer pressure device is installed on the blocking device, the fixed end of the buffer pressure device can be connected to the mounting component, and the telescopic end of the buffer pressure device can be connected to the blocking component. In this way, when the blocking component collides with the AGV, the blocking component can drive the telescopic end of the buffer pressure device to move towards the fixed end of the buffer pressure device under the action of the collision force generated by the collision with the AGV. This allows the buffer pressure device to buffer the movement of the blocking component, thereby buffering the movement of the AGV.
[0013] In one alternative embodiment, the blocking member has an elastic force that deforms under external force and recovers its deformation when no external force is applied.
[0014] Beneficial effects: By designing the blocking component to have elasticity that allows it to deform under external force and recover its deformed shape when no external force is applied, the blocking component can deform when it collides with the AGV, thus protecting the components on the AGV and preventing hard contact between the blocking component and the AGV that could damage the components. When the AGV restarts operation, the blocking component separates from the AGV, and the deformed blocking component can then recover its original shape under the action of elasticity, preparing for the next collision with the AGV. Specifically, the blocking component is made of polyurethane.
[0015] In an optional embodiment, a guide assembly is further included, the guide assembly comprising at least two guide members, both of which are disposed between the mounting member and the blocking member, and the two guide members are respectively disposed on both sides of the buffer member, one end of each guide member being connected to the blocking member, and the other end passing through the mounting member.
[0016] Beneficial effects: By using a guide assembly positioned between the mounting component and the blocking component, specifically comprising two guide members (guide rods in this embodiment), the two guide members are respectively positioned on both sides of the buffer component. One end of each guide member is connected to the blocking component, and the other end passes through the mounting component. Thus, when the blocking component collides with the AGV, the guide member moves relative to the mounting component under the action of the blocking component, thereby providing guidance for the blocking component. Furthermore, since the buffer component is a buffer pressure regulator, it can only accept radial forces. By providing guide members on both sides of the buffer component, when the blocking component transmits pressure to the buffer component, the guide members can guide this pressure into a radial force. This ensures that the buffer pressure regulator only receives radial forces, thus the guide members also provide protection for the buffer component.
[0017] In one optional embodiment, the mounting member has at least two guide portions, each guide portion corresponding to a guide member, and one end of the guide member passing through the mounting member is adapted to be inserted into the guide portion.
[0018] Beneficial effects: By providing two guide portions on the mounting component, which are guide holes in this embodiment, and each guide portion corresponding to a guide member, the end of the guide member that passes through the mounting component can be directly inserted into the guide portion. Thus, when the blocking member moves the guide member, the guide member can move relative to the mounting component through the guide portion and provide guidance for the movement of the blocking member.
[0019] In one alternative embodiment, the guide assembly further includes at least two linear bearings, each of which is disposed within a guide portion, and one end of the guide member passing through the guide portion is adapted to pass through the linear bearing.
[0020] Beneficial effects: By including two linear bearings in the guide assembly, each linear bearing is set in a guide section. When the end of the guide component passes through the mounting component and is inserted into the guide section, it can directly pass through the linear bearing. Thus, when the blocking component drives the guide component to move relative to the mounting component, the guide component can move relative to the mounting component through the linear bearing. This can effectively reduce the friction between the guide component and the mounting component, thereby helping to improve the service life of the guide component and the mounting component.
[0021] In one optional embodiment, a limiting portion is provided at the end of any of the guide members away from the blocking member, and the cross-sectional dimension of the limiting portion is larger than the cross-sectional dimension of the guide portion, so as to limit the guide member.
[0022] Beneficial effects: By setting a limiting part on the guide member, which is a limiting block in this embodiment, the limiting part is specifically set at the end of the guide member away from the blocking member, and the cross-sectional size of the limiting part is larger than the cross-sectional size of the guide member, so that when the end of the guide member away from the blocking member passes through the guide part on the mounting member, the limiting part can limit the guide member to avoid the guide member from completely detaching from the mounting member.
[0023] In one optional embodiment, the guide assembly further includes at least two elastic members, any one of which is sleeved on one of the guide members, and both ends of any one of the elastic members abut against the mounting member and the blocking member, respectively, and any one of the elastic members is elastic.
[0024] Beneficial effects: By including two elastic elements in the guide assembly, which are springs in this embodiment, each elastic element is sleeved on a guide element. When the elastic element is sleeved on the guide element, its two ends abut against the mounting element and the blocking element, respectively. At the same time, the elastic element is elastic, so when the blocking element drives the guide element to move relative to the mounting element, the elastic element can generate elastic force through the mutual approach of the blocking element and the mounting element. This elastic force can buffer the collision force generated by the collision between the blocking element and the AGV, thus further improving the buffering effect of the blocking device.
[0025] In one alternative embodiment, the fixing component includes a base and a drive member. The base is adapted to be disposed on the ground on one side of the track, and the drive member is disposed on the base. The drive end of the drive member is connected to the mounting member, and the drive end of the drive member is configured as the drive end of the fixing component.
[0026] Beneficial effects: By setting a fixed component including a base and a drive component, the drive component in this embodiment is a cylinder. The base can be set on the ground on one side of the track, and the drive component can be set on the base. At the same time, the drive end of the drive component can be connected to the mounting component, so that the drive end of the drive component can drive the mounting component to move above the track, thereby enabling the mounting component to drive the blocking component and the buffer component to move synchronously above the track.
[0027] In one alternative embodiment, the fixing component further includes a stabilizer disposed on the drive component.
[0028] Beneficial effects: By using a stabilizer on the drive component, which in this embodiment is a speed control valve, and since the drive component is a cylinder, the stabilizer can provide a stable effect on the movement of the drive end of the drive component when it is installed on the drive component, so that the drive component can stably drive the mounting component above the track.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0037] The following is combined with Figure 1 and Figure 2 The following describes embodiments of the present invention.
[0038] According to an embodiment of the present invention, in one aspect, a blocking device is provided for blocking an AGV moving along a track, such as... Figure 1 and Figure 2As shown, the system includes a fixing component 1 and a blocking component 2. The fixing component 1 is set on the ground on one side of the track. The blocking component 2 includes a mounting component 21, a blocking component 22, and a buffer component 23. The mounting component 21 is connected to the drive end of the fixing component 1. One end of the buffer component 23 is connected to the mounting component 21, and the other end of the buffer component 23 is connected to the blocking component 22. The blocking component 22 is adapted to contact the AGV. The drive end of the fixing component 1 is adapted to drive the blocking component 2 to move above the track so that the blocking component 22 corresponds to the AGV. When the blocking component 22 collides with the AGV, the buffer component 23 is configured to buffer the movement of the AGV and decelerate the AGV to a stop.
[0039] The aforementioned blocking device comprises a fixed assembly 1 mounted on the ground on one side of the track and a blocking assembly 2 mounted on the fixed assembly 1. The blocking assembly 2 includes a mounting member 21, a blocking member 22, and a buffer member 23. In this embodiment, the mounting member 21, the blocking member 22, and the buffer member 23 are respectively a mounting plate, a blocking block, and a buffer pressure device. The mounting member 21 is connected to the driving end of the fixed assembly 1, so that the mounting member 21 can move above the track under the drive of the driving end of the fixed assembly 1. One end of the buffer member 23 is connected to the mounting member 21, and the other end is connected to the blocking member 22. When the mounting member 21 moves above the track, it can drive the buffer member 23 and the blocking member 22 to move synchronously above the track, so that the blocking member 22 can correspond to the AGV moving on the track. In this way, the blocking member 22 can contact the AGV and block it.
[0040] In addition, when the blocking member 22 collides with the AGV, the buffer member 23 can buffer the movement of the AGV and decelerate the AGV, so that the AGV can slowly decelerate to a stop. Through the buffer member 23, the collision force generated when the AGV collides with the blocking member 22 can be reduced, and the collision between the blocking member 22 and the AGV can occur smoothly. This reduces the noise generated when the AGV collides with the blocking member 22 and avoids the risk of materials falling off the AGV. At the same time, since the collision force between the AGV and the blocking member 22 is reduced, the AGV and the blocking device will not be easily damaged.
[0041] In one embodiment, such as Figure 1 and Figure 2 As shown, the buffer 23 is a buffer pressure device. The fixed end of the buffer pressure device is connected to the mounting part 21, and the telescopic end of the buffer pressure device is connected to the blocking part 22.
[0042] The blocking device described above uses a buffer 23 as a buffer pressure device. Since the buffer pressure device is a conventional instrument, it will not be described in detail in this embodiment. When the buffer pressure device is installed on the blocking device, the fixed end of the buffer pressure device can be connected to the mounting part 21, and the telescopic end of the buffer pressure device can be connected to the blocking part 22. In this way, when the blocking part 22 collides with the AGV, the blocking part 22 can drive the telescopic end of the buffer pressure device to move towards the fixed end of the buffer pressure device under the action of the collision force generated by the collision with the AGV. This allows the buffer pressure device to buffer the movement of the blocking part 22, thereby buffering the movement of the AGV.
[0043] In one embodiment, such as Figure 1 and Figure 2 As shown, the blocking member 22 has an elastic force that deforms under external force and recovers its deformation when no external force is applied.
[0044] The aforementioned blocking device, by providing the blocking member 22 with elastic force that deforms under external force and recovers its deformation when no external force is applied, allows the blocking member 22 to deform when it collides with the AGV, thus protecting the components on the AGV and preventing hard contact between the blocking member 22 and the AGV that could damage the components. When the AGV restarts operation, the blocking member 22 separates from the AGV, and at this time, the deformed blocking member 22 can recover its original shape under the action of elastic force, preparing for the next collision with the AGV. Specifically, the material of the blocking member 22 is polyurethane.
[0045] In one embodiment, such as Figure 1 and Figure 2 As shown, it also includes a guide assembly 3, which includes at least two guide members 31. Both guide members 31 are disposed between the mounting member 21 and the blocking member 22, and the two guide members 31 are respectively disposed on both sides of the buffer member 23. One end of any guide member 31 is connected to the blocking member 22, and the other end is disposed through the mounting member 21.
[0046] The blocking device described above uses a guide assembly 3 disposed between the mounting member 21 and the blocking member 22. The guide assembly 3 specifically includes two guide members 31, which are guide rods in this embodiment. The two guide members 31 are respectively disposed on both sides of the buffer member 23, and one end of each guide member 31 is connected to the blocking member 22, while the other end passes through the mounting member 21. Thus, when the blocking member 22 collides with the AGV, the guide member 31 moves relative to the mounting member 21 under the action of the blocking member 22, thereby providing guidance for the blocking member 22.
[0047] In addition, since the buffer 23 is a buffer pressure absorber, the buffer 23 can only accept radial force. By providing guides 31 on both sides of the buffer 23, when the blocking member 22 transmits pressure to the buffer 23, the guides 31 can guide the pressure into a radial force. In this way, the buffer pressure absorber will only receive radial force. Therefore, the guides 31 can also provide protection for the buffer 23.
[0048] In one embodiment, such as Figure 1 and Figure 2 As shown, the mounting component 21 has at least two guide portions, each guide portion corresponding to a guide member 31, and one end of the guide member 31 that passes through the mounting component 21 is adapted to be inserted into the guide portion.
[0049] The blocking device described above has two guide portions on the mounting member 21. In this embodiment, the guide portions are guide holes. Each guide portion corresponds to a guide member 31, so that one end of the guide member 31 that passes through the mounting member 21 can be directly inserted into the guide portion. When the blocking member 22 moves the guide member 31, the guide member 31 can move relative to the mounting member 21 through the guide portion and provide guidance for the movement of the blocking member 22.
[0050] In one embodiment, such as Figure 1 and Figure 2 As shown, the guide assembly 3 also includes at least two linear bearings 32, each of which is disposed in a guide portion, and one end of the guide member 31 passing through the guide portion is adapted to pass through the linear bearing 32.
[0051] The blocking device described above also includes two linear bearings 32 by setting the guide assembly 3. Each linear bearing 32 is set in a guide section. So when the end of the guide member 31 that passes through the mounting member 21 is inserted into the guide section, it can be directly inserted into the linear bearing 32. Then, when the blocking member 22 drives the guide member 31 to move relative to the mounting member 21, the guide member 31 can move relative to the mounting member 21 through the linear bearing 32. In this way, the friction between the guide member 31 and the mounting member 21 can be effectively reduced, which is conducive to improving the service life of the guide member 31 and the mounting member 21.
[0052] In one embodiment, such as Figure 1 and Figure 2 As shown, a limiting part is provided at the end of any guide member 31 away from the blocking member 22. The cross-sectional dimension of the limiting part is larger than the cross-sectional dimension of the guide part, so as to limit the guide member 31.
[0053] The blocking device described above, through a limiting part provided on the guide member 31, which in this embodiment is a limiting block, is specifically provided at the end of the guide member 31 away from the blocking member 22, and the cross-sectional dimension of the limiting part is larger than the cross-sectional dimension of the guide part, so that when the end of the guide member 31 away from the blocking member 22 passes through the guide part on the mounting member 21, the limiting part can limit the guide member 31 to prevent the guide member 31 from completely detaching from the mounting member 21.
[0054] In one embodiment, such as Figure 1 and Figure 2 As shown, the guide assembly 3 also includes at least two elastic members 33, each elastic member 33 is sleeved on a guide member 31, and the two ends of each elastic member 33 abut against the mounting member 21 and the blocking member 22 respectively, and each elastic member 33 is elastic.
[0055] The blocking device described above also includes two elastic elements 33 by setting the guide component 3. In this embodiment, the elastic elements 33 are springs. Each elastic element 33 is sleeved on a guide component 31. When the elastic element 33 is sleeved on the guide component 31, the two ends of the elastic element 33 abut against the mounting component 21 and the blocking component 22, respectively. At the same time, the elastic element 33 is elastic, so when the blocking component 22 drives the guide component 31 to move relative to the mounting component 21, the elastic element 33 can generate a spring force through the mutual approach of the blocking component 22 and the mounting component 21. This spring force can buffer the collision force generated by the collision between the blocking component 22 and the AGV, which helps to further improve the buffering effect of the blocking device.
[0056] In one embodiment, such as Figure 1 and Figure 2 As shown, the fixing component 1 includes a base 11 and a drive member 12. The base 11 is adapted to be set on the ground on one side of the track. The drive member 12 is set on the base 11, and the drive end of the drive member 12 is connected to the mounting member 21. The drive end of the drive member 12 is configured as the drive end of the fixing component 1.
[0057] The blocking device described above includes a base 11 and a driving component 12, which is a cylinder in this embodiment. The base 11 can be placed on the ground on one side of the track, and the driving component 12 can be placed on the base 11. The driving end of the driving component 12 can be connected to the mounting component 21, so that the driving end of the driving component 12 can drive the mounting component 21 to move above the track, thereby enabling the mounting component 21 to drive the blocking component 22 and the buffer component 23 to move synchronously above the track.
[0058] In one embodiment, such as Figure 1 and Figure 2As shown, the fixing component 1 also includes a stabilizer 13, which is disposed on the driving component 12.
[0059] The blocking device described above, through the stabilizing member 13 provided on the driving member 12, the stabilizing member 13 is a speed regulating valve in this embodiment. Since the driving member 12 is a cylinder, when the stabilizing member 13 is installed on the driving member 12, the stabilizing member 13 can provide a stabilizing effect on the movement of the driving end of the driving member 12, so that the driving member 12 can stably drive the mounting member 21 above the track.
[0060] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
