When the blocking unit is in the blocking state, the driving connecting rod is perpendicular to the driving push-pull rod, and the distance between the driving end of the blocking connecting rod relative to the driving push-pull rod in the first horizontal direction is greater than the distance between the driving end of the blocking stop lever relative to the driving push-pull rod in the first horizontal direction. The end of the driving push-pull rod connected to the first driving assembly is defined as the driving end.
[0008] In one embodiment of the present application, the blocking unit further comprises a rotating connecting rod arranged vertically, both ends of the rotating connecting rod vertically penetrating the rotating supports and rotatably connected to the fixed supports. The axes of the blocking stop lever, the blocking connecting rod, and the rotating connecting rod are not coplanar. When the blocking unit is in the blocking state, the distance between the driving end of the blocking connecting rod relative to the driving push-pull rod in the first horizontal direction is greater than the distance between the driving end of the rotating connecting rod relative to the driving push-pull rod in the first horizontal direction.
[0009] In one embodiment of the present application, the middle part of the driving connecting rod is concave in the horizontal direction to form an avoiding part for the rotating connecting rod.
[0010] In one embodiment of the present application, the first driving assembly comprises a driving motor installed on the buffer support, a first rotating shaft and a second rotating shaft arranged vertically, a first gear coaxially arranged on the first rotating shaft, a second gear coaxially arranged on the second rotating shaft, a first rack meshingly connected to the first gear for transmission, and a second rack meshingly connected to the second gear for transmission.

The first rack and the second rack are slidingly connected to the buffer support along the first horizontal direction. The first rack is fixedly connected to the driving push-pull rod of one blocking unit of the same blocking assembly.

[0014] The above technical solutions of the present application have the following advantages compared with the prior art: The present application forms a buffer space extending along the first horizontal direction by arranging the buffer base and the buffer support arranged thereon, so that multiple drawer carriers can be stored in the space, thereby providing a structural basis for the centralized buffering and automatic transfer of the drawer carriers. The buffer support is fixed relative to the buffer base, so that the buffer space as a whole remains stable and will not deform or shake due to the operation of the moving device.

When the blocking unit is in the blocking state, the projection area of the blocking unit and the buffer space in the first horizontal direction at least partially overlaps, so that the blocking end of the blocking unit enters the movement path of the drawer carrier, thereby limiting the drawer carrier from the side or front and preventing it from continuously sliding out of the buffer space; when the blocking unit is in the release state, the projection of the blocking unit and the buffer space no longer overlaps, so that the drawer carrier can freely enter and exit the buffer space or be taken out by the transmission structure.

DETAILED DESCRIPTION
[0019] The present application will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present application and implement it, but the embodiments are not limiting to the present application. Embodiment 1:
[0020] Reference Figure 1With Figure 2 As shown in FIG. 1, the embodiment 1 discloses a carrier caching device, which comprises a device body 100 and a blocking mechanism 200.
[0021] The device body 100 comprises a caching base 110 and a caching support 120. The caching support 120 is arranged across the caching base 110, and a caching space 130 extending along a first horizontal direction is formed between the two, for accommodating a plurality of drawer carriers 300 or magazine devices 400. The first horizontal direction can be understood as the length direction of the caching space 130. The caching support 120 can be a frame welded structure or a metal profile structure, which is fixedly connected with the caching base 110, so that the caching space 130 remains stable and does not deform or shake under the action of a mobile device or an external force, thereby ensuring that the magazine device 400 and / or the drawer carrier 300 in the magazine device 400 can be arranged in order and reliably parked.
[0022] The blocking mechanism 200 is arranged at the end of the caching support 120 along the first horizontal direction, for controlling whether the magazine device 400 and / or the drawer carrier 300 is allowed to enter or exit the caching space 130. The blocking mechanism 200 comprises a first driving assembly 210 and at least one set of blocking assemblies 220. The blocking assemblies 220 are installed at the end of the caching support 120 along the first horizontal direction. The blocking assemblies 220 comprise two blocking units 221 arranged side by side along a second horizontal direction. The second horizontal direction can be understood as the width direction of the caching space 130. The two blocking units 221 are installed on the caching support 120 and connected with the first driving assembly 210. The blocking units 221 are arranged to have a blocking state and a release state during synchronous driving of the first driving assembly 210: when the blocking units 221 are in the blocking state, their projections in the first horizontal direction at least partially coincide with the caching space 130; when the blocking units 221 are in the release state, the overlapping part of their projections in the first horizontal direction with the caching space 130 is eliminated.
[0023] That is, the blocking units 221 have two working states of the blocking state and the release state under the driving of the first driving assembly 210. When in the release state, the two blocking units 221 completely or partially exit the projection area of the caching space 130 in the first horizontal direction, at which time the drawer carrier 300 and / or the magazine device 400 can freely enter or exit the caching space 130 along the first horizontal direction. When in the blocking state, at least a part of the blocking units 221 enters the projection range of the caching space 130, and overlaps with the movement path of the drawer carrier 300 and the magazine device 400, forming a limiting surface from the front end or the side end, which prevents the drawer carrier 300 and / or the magazine device 400 from sliding out of the caching space 130 along the first horizontal direction due to gravity or inertia.
[0024] The projection of the blocking unit 221 and the cache space 130 in the first horizontal direction is in a coincident relationship, which forms a physical block to the drawer carrier 300; by arranging the two blocking units 221 side by side, the limiting area covers the second horizontal direction (the width direction of the cache space 130) of the cache space 130, so that the drawer carrier 300 and / or the clip device 400 can be blocked even if there is a lateral offset. In this way, the drawer carrier 300 and / or the clip device 400 are prevented from falling or falling out during caching, improving the caching safety. In addition, the first drive assembly 210 is used to realize the synchronous action of the double blocking units 221, ensuring the reliability of the limiting and the consistency of the action.
[0025] Referring to Figure 1 With Figure 2 As shown, the carrier caching device further includes a second drive assembly mounted on the cache base 110, and a transmission assembly 140 arranged inside the cache base 110. The second drive assembly is used to drive the transmission assembly 140 to run along the first horizontal direction.
[0026] The transmission assembly 140 is located in the inner side area of the cache base 110, and extends along the first horizontal direction like the cache space 130. The second drive assembly is connected with the transmission assembly 140 and can drive the transmission assembly 140 to run, so that the clip device 400 actively moves along the first horizontal direction without the need for manual pushing, improving the efficiency of the carrier entering and leaving the cache area, reducing manual intervention, and avoiding shaking, jamming or falling of the carrier caused by pushing and pulling. This setting also enables the transmission assembly 140 to be connected with external transmission equipment, so that the clip device 400 directly enters and leaves the cache space 130, thereby further improving the efficiency of the carrier entering and leaving the cache area.
[0027] In specific use, the clip device 400 can be placed on the transmission assembly 140, and when the second drive assembly is started, the transmission assembly 140 drives the clip device 400 to be transported into the cache space 130 or transported out of the cache space 130. When the clip device 400 is transported to a predetermined position in the cache space 130, the blocking mechanism 200 acts to make the blocking unit 221 in a blocking state, thereby preventing the drawer carrier 300 and / or the clip device 400 from being separated or falling off from the transmission assembly 40; when the drawer carrier 300 needs to be taken out or inserted, the blocking unit 221 is switched to a release state, at which time the drawer carrier 300 can be taken out or inserted from the clip device 400 by the plug-in mechanism / holding mechanism of the external device, and the clip device 400 can also smoothly leave the cache space under the drive of the transmission assembly 140.
[0028] Referring to Figure 1 With Figure 2As shown, the transmission assembly 140 specifically includes two transmission belts 141 arranged in parallel with each other and extending along the first horizontal direction, and serving as a direct bearing surface for bearing the bottom of the cartridge device 400 to enable the cartridge device 400 to move thereon. A transmission channel 142 is formed between the two transmission belts 141, which is used to define the running area of the cartridge device 400 to prevent the drawer carrier 300 from deviating, tilting or sinking during the conveying process. The transmission belt 141 in the embodiment can be understood as a synchronous belt and pulley transmission structure, which generally has a synchronous belt and a synchronous pulley. The second driving assembly is generally a motor and transmission shaft transmission structure adapted to such a synchronous belt and pulley transmission structure. Therefore, the specific structure of the second driving assembly and the transmission assembly 140 will not be described in detail.
[0029] In operation, the cartridge device 400 is placed above the two transmission belts 141 with the bottom portion spanning between the two transmission belts 141. The drawer cartridge device 400 moves along the first horizontal direction under the drive of the transmission belts 141, and the transmission channel 142 ensures that the cartridge device 400 maintains a stable posture during movement and does not swing left and right or deviate from the conveying path. This structure enables the cartridge device 400 to be reliably supported and smoothly enter or exit the buffer space 130, and cooperates with the action of the blocking mechanism 200 to achieve automatic buffering, releasing and limiting control.
[0030] Referring to Figures 1 to 4 As shown, the blocking unit 221 includes two fixed supports 2211 arranged in parallel with each other, two rotating supports 2212 arranged in parallel between the two fixed supports 2211, a blocking stop lever 2213 and a blocking link 2214 arranged vertically and fixedly connected to the two rotating supports 2212 at both ends, a drive link 2215 rotatably connected to one end of the blocking link 2214, and a drive push-pull rod 2216 hingedly connected to the other end of the drive link 2215. Among them, the fixed support 2211 is fixedly installed on the buffer bracket 120. The rotating support 2212 is rotatably installed on the fixed support 2211. The end of the drive push-pull rod 2216 away from the drive link 2215 is connected to the first driving assembly 210. The drive push-pull rod 2216 is limited to reciprocate along the first horizontal direction under the drive of the first driving assembly 210 to realize the state switching of the blocking unit 221. When the blocking unit 221 is in the blocking state, the drive link 2215 is perpendicular to the drive push-pull rod 2216, and the distance between the blocking link 2214 and the drive end of the drive push-pull rod 2216 in the first horizontal direction is greater than the distance between the blocking stop lever 2213 and the drive end of the drive push-pull rod 2216 in the first horizontal direction. The end of the drive push-pull rod 2216 connected to the first driving assembly 210 is defined as the drive end.
[0031] In the blocking unit 221, the driving push-pull rod 2216 reciprocates along the first horizontal direction (i.e. the length direction of the buffer space 130), and the driving link 2215 converts the linear motion into the synchronous rotation of the blocking link 2214 and the blocking stopper 2213 with the rotating support 2212. When the driving push-pull rod 2216 moves to exert a pushing force along the first horizontal direction to the outside of the buffer space 130, the driving link 2215 drives the blocking link 2214 and the blocking stopper 2213 to rotate synchronously, so that the blocking stopper 2213 rotates into the projection area of the buffer space 130 along the first horizontal direction and enters the running path of the drawer carrier 300 and the magazine device 400, thereby limiting and blocking the drawer carrier 300 and the magazine device 400. At this time, if the drawer carrier 300 or the magazine device 400 slides along the first horizontal direction to the outside, it will be blocked in the buffer space 130 by contacting the blocking stopper 2213.
[0032] Specifically, when the driving push-pull rod 2216 exerts a pushing force on the driving link 2215 under the driving of the first driving assembly 210, the driving link 2215 drives the blocking link 2214 and the blocking stopper 2213 to rotate to the inside of the buffer space 130, so that the blocking stopper 2213 enters the running path of the drawer carrier 300 and forms a block; as the driving push-pull rod 2216 moves further, a 90° angle is gradually formed between the driving link 2215 and the driving push-pull rod 2216, i.e. the driving link 2215 is perpendicular to the driving push-pull rod 2216, forming a dead point (as shown in Figure 6 At this time, the blocking unit is in a blocking state.
[0033] In this dead point state, the torque generated by the external force F1 exerted by the drawer carrier 300 or the magazine device 400 on the blocking stopper 2213 is counteracted by the torque generated by the reaction force F2 exerted by the driving link 2215 on the blocking link 2214. Therefore, even if the first driving assembly 210 stops driving or no longer exerts an external force, the blocking unit still remains in the blocking state and will not be automatically released.
[0034] As shown in Figure 7 When it is necessary to release the blocking limitation, the driving push-pull rod 2216 moves in the opposite direction, i.e. exerts a pulling force along the first horizontal direction to the inside of the buffer space 130, so that the driving link 2215 exits the dead point position, the blocking link 2214 and the blocking stopper 2213 rotate reversely, the blocking stopper 2213 exits the projection area of the buffer space 130 along the first horizontal direction, and the drawer carrier 300 and the magazine device 400 can freely enter and exit the buffer space 130 along the first horizontal direction. At this time, the blocking unit is in a release state.
[0035] Through the above structure and motion relationship, the blocking unit 221 realizes the conversion of linear motion to rotary motion, and realizes stable self-locking through the geometric dead point, preventing the drawer carrier 300 and / or the cartridge device 400 from sliding out of the buffer space 130 due to inertia or vibration from the source, ensuring the safety and reliability of the carrier during movement or handling.
[0036] Referring to Figure 3 As shown, the blocking unit 221 further includes a vertically arranged rotating link 2217. The upper and lower ends of the rotating link 2217 are vertically penetrated through the rotating support 2212 and are rotatably connected with the fixed support 2211. The axes of the blocking stop lever 2213, the blocking link 2214, and the rotating link 2217 are not coplanar. Moreover, when the blocking unit 221 is in the blocking state, the distance of the blocking link 2214 from the driving end of the driving push-pull rod 2216 in the first horizontal direction is greater than the distance of the rotating link 2217 from the driving end of the driving push-pull rod 2216 in the first horizontal direction.
[0037] In a specific structure, the rotating link 2217 is installed together with the blocking link 2214 and the blocking stop lever 2213 in the same pair of rotating supports 2212, which acts as an auxiliary support and force transmission node, so that the blocking stop lever 2213 is not only subjected to bending moment by the blocking link 2214 when subjected to force, thereby improving the overall stability and impact resistance of the entire blocking mechanism 200. Through this three-link spatial arrangement, the impact force loaded on the blocking stop lever 2213 can be partially transmitted to the rotating link 2217, avoiding the concentration of force on the driving link 2215 or the blocking link 2214, so that the structure is more balanced in force.
[0038] When the blocking unit 221 is in the blocking state, the distance of the blocking link 2214 from the driving end in the first horizontal direction is the greatest, while the distance of the rotating link 2217 from the driving end in the first horizontal direction is slightly smaller, so that the driving link 2215, the blocking link 2214, and the rotating link 2217 form a spatial triangular structure with a moment balance relationship. When the drawer carrier 300 or the cartridge device 400 applies an external pushing force in the first horizontal direction, the force first acts on the blocking stop lever 2213, and is then dispersed to the rotating support 2212 through the blocking link 2214 and the rotating link 2217, so that the acting force is no longer concentrated on a single point of the driving push-pull rod 2216 or the driving link 2215. Therefore, the dead point locking position formed by the driving push-pull rod 2216 is not damaged, and even in the case of device vibration, carrier impact, or unbalanced load, the blocking stop lever 2213 can still be reliably maintained at the limiting position within the buffer space 130, thereby further enhancing the anti-falling effect and operation stability.
[0039] The blocking unit 221 is provided with a rotating connecting rod 2217, and the blocking rod 2213 and the blocking connecting rod 2214 form a spatial three-point force system with the rotating connecting rod 2217, so that when an external force is applied to the blocking mechanism 200, the external force can be transmitted to the rotating support 2212 and the buffer support 120 along two different paths respectively, instead of being concentrated on the hinged point of the driving connecting rod 2215 and the blocking connecting rod 2214. This structure effectively improves the impact resistance, eccentric load resistance and vibration resistance of the blocking mechanism 200, and ensures that the blocking mechanism 200 can maintain a stable blocking state in a complex operating environment.
[0040] Referring to Figure 5 As shown in the drawings, in the embodiment, the middle part of the driving connecting rod 2215 is concave inward in the horizontal direction, forming an avoidance part 2218 which avoids the rotating connecting rod 2217. The avoidance part 2218 is arranged at the middle position of the length direction of the driving connecting rod 2215, and is used to provide necessary structural space for the rotating connecting rod 2217 during the movement and rotation of the driving connecting rod 2215 with the driving push-pull rod 2216. Moreover, the distance between the blocking connecting rod 2214 and the rotating connecting rod 2217 can be slightly increased on the premise of compact structure, so as to exert a larger torque on the rotation process of the rotating support 2212, and improve the feasibility of normal operation of the blocking unit.
[0041] Specifically, when the driving push-pull rod 2216 drives the driving connecting rod 2215 to rotate and drives the blocking connecting rod 2214 and the blocking rod 2213 to switch from the release state to the blocking state, the relative motion trajectory between the rotating connecting rod 2217 and the driving connecting rod 2215 will be close. If the middle part of the driving connecting rod 2215 is a straight line structure, when the blocking unit 221 approaches the dead point position, the driving connecting rod 2215 may interfere with or collide with the rotating connecting rod 2217, affecting the stability of the mechanism movement. By arranging the avoidance part 2218, when the driving connecting rod 2215 rotates to the limit position, the concave area of the driving connecting rod 2215 just reserves the motion space for the rotating connecting rod 2217, so that the driving connecting rod 2215 and the rotating connecting rod 2217 always maintain the necessary gap during the whole movement process, avoiding the jamming, wear or movement instability caused by contact interference.
[0042] Referring to Figure 3As shown, the first driving assembly 210 includes a driving motor 2101 mounted on the buffer support 120, a first rotating shaft 2102 and a second rotating shaft 2103 arranged vertically, a first gear 2104 coaxially arranged on the first rotating shaft 2102, a second gear 2105 coaxially arranged on the second rotating shaft 2103, a first rack 2106 in meshing transmission with the first gear 2104, and a second rack 2107 in meshing transmission with the second gear 2105. The first rotating shaft 2102 and the second rotating shaft 2103 are arranged side by side along the second horizontal direction and are simultaneously in driving connection with the driving motor 2101 to realize synchronous and same-direction rotation of the two rotating shafts. The first rotating shaft 2102 and the second rotating shaft 2103 are rotatably mounted on the buffer support 120. The driving motor 2101 is mounted on the buffer support 120. Specifically, a synchronous pulley mechanism 21013 is arranged between the first rotating shaft 2102 and the second rotating shaft 2103, the output end of the driving motor 2101 is also provided with a driving synchronous pulley (not marked in the figure), and the first rotating shaft 2102 and the second rotating shaft 2103 are driven to rotate synchronously through the synchronous pulley mechanism 21013. That is, a driven synchronous pulley (not marked in the figure) is fixed to the end of the first rotating shaft 2102 and the second rotating shaft 2103 respectively, and the synchronous pulley is connected through a synchronous belt, the synchronous belt is wound around the driving synchronous pulley and the driven synchronous pulley at the same time, so as to realize synchronous and same-direction rotation of the first rotating shaft 2102 and the second rotating shaft 2103. The first rack 2106 and the second rack 2107 are both in sliding connection with the buffer support 120 along the first horizontal direction. Specifically, the first rack 2106 and the second rack 2107 are in sliding connection with the buffer support 120 through a first sliding pair 21010 (which can be selected as a standard part, including a track and a sliding block matched with the track). The first rack 2106 is fixedly connected with the driving push-pull rod 2216 of one of the blocking units 221 of the same group of blocking assemblies 220, and the second rack 2107 is fixedly connected with the driving push-pull rod 2216 of the other blocking unit 221 in the same group of blocking assemblies 220. The first rack 2106 is located on the same side of the first gear 2104 in the second horizontal direction, and the second rack 2107 is located on the same side of the second gear 2105 in the second horizontal direction. For example, the first rack 2106 is located on the right side of the first gear 2104; and the second rack 2107 is located on the right side of the second gear 2105. Figure 3
[0043] In the specific working process, after the driving motor 2101 is started, the first rotating shaft 2102 and the second rotating shaft 2103 are simultaneously driven to rotate in the same direction, the first gear 2104 fixed on the first rotating shaft 2102 rotates to drive the first rack 2106 in meshing transmission with the first gear 2104 to move linearly along the first horizontal direction; the second gear 2105 fixed on the second rotating shaft 2103 rotates to drive the second rack 2107 in meshing transmission with the second gear 2105 to move linearly along the first horizontal direction, and the second rack 2107 keeps synchronization with the first rack 2106 in the same direction, equal displacement.
[0044] The end of the first rack 2106 is fixedly connected to the drive push-pull rod 2216 of one of the blocking units 221 of the same group of blocking assemblies 220, and the end of the second rack 2107 is fixedly connected to the drive push-pull rod 2216 of another blocking unit 221 of the same group of blocking assemblies 220. Therefore, when the first gear 2104 drives the first rack 2106 to move along the first horizontal direction towards the outside of the buffer space 130, the first blocking unit 221 is pushed to the blocking position, and at the same time, the second gear 2105 drives the second rack 2107 to move in the same direction, so that the other second blocking unit 221 also enters the blocking state; when the first gear 2104 and the second gear 2105 rotate reversely, the first rack 2106 and the second rack 2107 move reversely along the first horizontal direction, and the two blocking units 221 simultaneously exit the transmission path of the buffer space 130, thereby forming a release state.
[0045] The first drive assembly 210 converts the rotary motion of the drive motor 2101 into the linear motion of the drive push-pull rods 2216 of the two blocking units 221 by using the first gear 2104 to cooperate with the first rack 2106 and the second gear 2105 to cooperate with the second rack 2107, thereby realizing synchronous control of the two blocking units 221. Since the first rack 2106 and the second rack 2107 are arranged on the same meshing side of the respective gears, the force direction and the motion direction of the two are kept consistent, avoiding the problems of one-side pushing and one-side pulling or inconsistent action time, thereby ensuring synchronous and reliable blocking action, and avoiding the situation of carrier skewing, jamming or impacting the buffer support 120.
[0046] Referring to Figure 8 As shown in another possible implementation, the blocking mechanism 200 includes two groups of blocking assemblies 220. The two groups of blocking assemblies 220 are arranged at the two end positions of the buffer support 120 along the first horizontal direction. Each group of blocking assemblies 220 is driven by the first drive assembly 210, and each group of blocking assemblies 220 is composed of two blocking units 221 arranged side by side along the second horizontal direction, thereby forming a blocking structure that can be simultaneously switched at both ends of the buffer space 130 along the first horizontal direction. This structure realizes bidirectional protection at both ends of the buffer space 130, avoids the problem of carrier inertia slip or over-limit caused by single-end limiting, and improves the anti-falling ability and operation stability of the system under complex working conditions.
[0047] Referring to Figure 8As shown, the first driving assembly 210 further comprises a third rack 2108 in mesh transmission with the first gear 2104, and a fourth rack 2109 in mesh transmission with the second gear 2105. The third rack 2108 and the fourth rack 2109 are slidingly connected to the buffer support 120 along the first horizontal direction. Specifically, the third rack 2108 and the fourth rack 2109 are slidingly connected to the buffer support 120 through a second sliding pair 21011 (which can be selected as a standard part including a track and a slider matched with the track) respectively. The third rack 2108 is fixedly connected with the driving push-pull rod 2216 of one blocking unit 221 of another set of blocking assemblies 220. The fourth rack 2109 is fixedly connected with the driving push-pull rod 2216 of another blocking unit 221 of the set of blocking assemblies 220. The first rack 2106 and the third rack 2108 are arranged on two sides of the first gear 2104 along the second horizontal direction respectively; the second rack 2107 and the fourth rack 2109 are arranged on two sides of the second gear 2105 along the second horizontal direction respectively.
[0048] Through the above structure, when the driving motor 2101 works, the first gear 2104 and the second gear 2105 rotate synchronously, not only driving the first rack 2106 and the second rack 2107 to drive the first set of blocking assemblies 220 to act, but also driving the third rack 2108 and the fourth rack 2109 to make the other set of blocking assemblies 220 to realize synchronous operation. In other words, the first gear 2104 can drive the first rack 2106 and the third rack 2108 at the same time, and the second gear 2105 can drive the second rack 2107 and the fourth rack 2109 at the same time, so as to realize the synchronous action of the two sets of blocking assemblies 220 under the driving of the same motor. The blocking units of the two sets of blocking assemblies 220 can simultaneously enter the blocking state or the release state in the same direction, that is, the two-end blocking assemblies 220 can be opened or closed at the same time by controlling the running direction of the driving motor 2101.
[0049] The present embodiment method only needs a set of driving motor 2101 and gear transmission mechanism, and can control the synchronous action of the two-end blocking assemblies 220 of the buffer device at the same time, without the need to install independent driving devices at both ends. In this way, not only the number of motors, transmission parts and other components is reduced, the manufacturing and maintenance costs are reduced, but also the problems of asynchronous action and inconsistent response time easily caused by double-end driving are avoided.
[0050] The first rack 2106 and the third rack 2108 are distributed on both sides of the first gear 2104, and the second rack 2107 and the fourth rack 2109 are distributed on both sides of the second gear 2105, so that the action force directions generated by the gear pairs on the two racks are opposite, thereby ensuring that the operation states of the blocking units of the two groups of blocking assemblies 220 remain consistent, whether entering the blocking state or exiting the release state, and synchronous and unified action effects can be achieved. In addition, since the same set of driving structures drives the two end blocking assemblies 220, when the buffer device moves, vibrates or is impacted by the vehicle, the blocking mechanisms 200 at both ends can still cooperatively maintain the closed state, preventing the drawer vehicle 300 and / or the magazine device 400 from sliding out or falling from either end.
[0051] In summary, the first driving assembly 210 of the embodiment realizes the control of two blocking ends by one driving mechanism, which not only reduces the structural complexity and cost, but also improves the consistency and reliability of the blocking action of the two ends, and is especially suitable for scenes that require bidirectional buffering or prevent falling during movement. Embodiment 2
[0052] The embodiment 2 also provides a vehicle buffer moving device, which includes a moving chassis and a vehicle buffer device arranged on the moving chassis. The moving chassis can be an automatic guided vehicle, a mobile robot platform or a track walking base, which is used to realize the movement and transfer of the buffer device between different stations of a production line. The vehicle buffer device adopts the technical solution of embodiment 1, which is not described here. The vehicle buffer device is fixedly installed on the upper part of the moving chassis by means of bolts, positioning blocks or welding, so that the buffer base 110 and the moving chassis form a stable connection structure, thereby maintaining the overall balance and reliability when the device is running, accelerating or passing through uneven ground.
[0053] During the working process, the moving chassis drives the entire vehicle buffer device to move along different stations of a production line. After moving to a specified position, the blocking mechanism 200 on the buffer device can be controlled to enter the release state as needed, so that the magazine device 400 can enter or exit the buffer space 130 along the first horizontal direction, or the drawer vehicle 300 can enter or exit the magazine device 400 in the buffer space 130 along the first horizontal direction; when the moving chassis is started again or in the transfer state, the blocking mechanism 200 returns to the blocking state, thereby limiting the vehicle from both ends of the buffer space 130, thereby preventing the drawer vehicle 300 or the magazine device 400 from sliding out or falling due to vehicle movement, inertia or vibration.
[0054] The carrier buffer mobile device integrates the storage, transfer and feeding and discharging functions of the carrier on the same device by integrally configuring the buffer device with the mobile chassis, and can complete the buffer and flow operation without manual handling or additional conveying devices. Meanwhile, the double-end protection provided by the blocking mechanism 200 ensures that the drawer carrier 300 is always in a controlled state during movement, thereby improving the automation degree, safety and stability of the system operation.
[0055] Obviously, the above embodiments are only examples for clearly illustrating the present application, and are not intended to limit the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, it is not necessary and impossible to enumerate all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
