Description
Technical Field
[0001] This utility model belongs to the field of logistics stacking and conveying equipment, and specifically relates to a buffer mechanism. Background Technology
[0002] In modern logistics systems, the stability, efficiency, and timeliness of conveying equipment are crucial. These factors directly affect not only the speed of goods turnover but also the operating costs and customer satisfaction of the entire supply chain. However, existing conveying equipment still has some shortcomings in terms of conveying stability, efficiency, and timeliness.
[0003] For example, in the prior patent for a logistics conveying and feeding device (application number CN202220296207.8), the device includes a conveying mechanism and a buffer mechanism, which are connected together. The device also includes two or more guiding mechanisms, which are respectively arranged on both sides of the conveying mechanism. The guiding mechanism includes a side push component and a side push drive component, which are drivenly connected to each other. The side push components on both sides of the conveying mechanism are positioned correspondingly. The buffer mechanism includes a buffer conveying component, which is connected to the conveying mechanism. The side push components on both sides of the conveying mechanism are positioned correspondingly to the buffer conveying component. In the prior patent's device, when goods are placed on both sides of the buffer conveyor assembly and goods need to be placed in the middle, in order to avoid the goods on both sides of the buffer conveyor assembly affecting the placement of the goods in the middle, two insertion drive assemblies are used to drive guide insertion plates to extend into the buffer conveyor assembly. The two guide insertion plates isolate the goods that have been conveyed into the buffer conveyor assembly at both ends, and finally the goods in the middle position are conveyed. At this time, the goods on the buffer conveyor assembly are arranged in a row and can be pushed. However, in the prior patent's device, this structural setting not only has relatively low buffering efficiency, affecting the loading time, but also only has one set of buffer structure (buffer conveyor assembly), which is relatively unstable during loading. Utility Model Content
[0004] To address the aforementioned problems, the present invention aims to provide a multi-level caching mechanism. This mechanism, through the cooperation of two-level caching components, can not only effectively improve caching efficiency, but also, through the design of the two-level caching structure with primary and secondary caching components, effectively improve the stability when caching goods.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows.

The right side of the second conveying structure and the right side of the second buffer structure both correspond to the second buffer loading component.
[0011] In this mechanism, goods are first received from the upper-level conveyor structure via a connecting conveyor structure, and then these goods are alternately conveyed to the first conveyor structure and the second conveyor structure.

The second pusher corresponds to the right side of the second conveying structure and the right side of the second buffer structure.

[0019] Furthermore, the first blocking component includes a first blocking cylinder and a first blocking block. The first blocking cylinder is disposed on the left side of the first conveying structure, and the first blocking cylinder is drivenly connected to the first blocking block.
[0020] The second blocking component includes a second blocking cylinder and a second blocking block. The second blocking cylinder is located on the right side of the second conveying structure, and the second blocking cylinder is drivenly connected to the second blocking block.
[0021] Furthermore, a third deflector assembly for preventing goods from falling off is provided on the side of the first buffer structure away from the first conveying structure, and the third deflector assembly corresponds to the position of the first pusher.
[0022] The second buffer structure has a fourth deflector assembly on the side away from the second conveying structure to prevent goods from falling off, and the fourth deflector assembly corresponds to the position of the second pusher.
[0023] Furthermore, the third blocking component includes a third blocking cylinder and a third blocking block.

[0024] The fourth blocking component includes a fourth blocking cylinder and a fourth blocking block. The fourth blocking cylinder is located on the side of the second buffer structure away from the second conveying structure, and the fourth blocking cylinder is drivenly connected to the fourth blocking block.
[0025] Furthermore, the connecting conveyor structure includes multiple connecting conveyor belts for receiving goods and multiple connecting electric rollers for conveying goods toward the first conveyor structure or the second conveyor structure. The multiple connecting conveyor belts and multiple connecting electric rollers are arranged alternately, and the left and right sides of the multiple connecting electric rollers are connected to the right side of the first conveyor structure and the left side of the second conveyor structure, respectively.
[0026] Furthermore, a feed blocking component is provided in the middle of the side of the primary buffer component near the secondary buffer component, and the feed blocking component corresponds to the multiple connecting conveyor belts.
[0027] The beneficial effects of this utility model are as follows: In this mechanism, goods are first received from the upper-level transmission structure via a connecting conveyor structure, and then these goods are alternately conveyed to the first conveyor structure and the second conveyor structure. When the first conveyor structure receives goods, it conveys the goods to its left side and, under the action of the first buffer loading component, sends them into the first buffer structure, and then, under the action of the first buffer structure, conveys them to the right side of the first buffer structure. When the second conveyor structure receives goods, it conveys the goods to its right side and, under the action of the second buffer loading component, sends them into the second buffer structure, and then, under the action of the second buffer structure, conveys them to the left side of the second buffer structure. That is, through the above structural design, the buffered goods can alternately enter the second-level buffer component through the left and right ends, and gradually accumulate from the middle of the second-level buffer component to both sides. Through the structural setting of this mechanism, not only can the buffering efficiency be effectively improved, but also the stability of buffering goods can be effectively improved through the design of the two-level buffer structure of the first-level buffer component and the second-level buffer component.

The right side of the second conveying structure 12 and the right side of the second buffer structure 22 are both corresponding to the second buffer loading component 4.
[0046] In this embodiment, the secondary cache component 2 is arranged in parallel behind the primary cache component 1, and the left side of the first conveying structure 11 corresponds to the left side of the first cache structure 21, and the right side of the second conveying structure 12 corresponds to the right side of the second cache structure 22.
[0047] In this embodiment, the first conveying structure 11, the second conveying structure 12, and the second buffer structure 22 are all composed of multiple electric rollers. These electric rollers are a conventional drive device that integrates a motor and a reducer inside the roller body. The electric rollers can select their direction of movement as needed, and the control of this direction of movement is existing technology. It is worth noting that for the first conveying structure 11, its multiple electric rollers rotate towards its left side to move the goods to its left; for the second conveying structure 12, its multiple electric rollers rotate towards its right side to move the goods to its right; for the first buffer structure 21, its multiple electric rollers rotate towards its right side to move the goods to its right; and for the second buffer structure 22, its multiple electric rollers rotate towards its left side to move the goods to its left.

[0053] In this embodiment, a first blocking component 5 for preventing goods from falling off is provided on the left side of the first conveying structure 11, so as to block the goods when the first conveying structure 11 conveys the goods to its left side, thereby preventing the goods from falling off the left side of the first conveying structure 11; a second blocking component 6 for preventing goods from falling off is provided on the right side of the second conveying structure 12, so as to block the goods when the second conveying structure 12 conveys the goods to its right side, thereby preventing the goods from falling off the right side of the second conveying structure 12.
[0054] In this embodiment, the first blocking component 5 includes a first blocking cylinder 51 and a first blocking block 52. The first blocking cylinder 51 is disposed on the left side of the first conveying structure 11, and the first blocking cylinder 51 is driven to connect with the first blocking block 52. The cylinder can drive the first blocking block 52 to rise and fall, so as to better block the goods.
[0055] The second blocking component 6 includes a second blocking cylinder 61 and a second blocking block 62. The second blocking cylinder 61 is located on the right side of the second conveying structure 12 and is driven to the second blocking block 62. The cylinder can drive the second blocking block 62 to rise and fall, so as to better block the goods.
[0056] In this embodiment, a third blocking component 7 is provided on the front side of the first buffer structure 21 away from the first conveying structure 11 to prevent the goods from falling off. The third blocking component 7 is positioned corresponding to the first pusher 33 so as to prevent the goods from falling off the first buffer structure 21 during the pushing process when the first pusher 33 pushes the goods on the left side of the first conveying structure 11 to the left side of the first buffer structure 21.
[0057] A fourth blocking component 8 is provided on the front side of the second buffer structure 22 away from the second conveying structure 12 to prevent the goods from falling off.

[0058] In this embodiment, the third blocking component 7 includes a third blocking cylinder 71 and a third blocking block 72.

The cylinder can drive the third blocking block 72 to rise and fall, so as to better block the goods.
[0059] The fourth blocking assembly 8 includes a fourth blocking cylinder 81 and a fourth blocking block 82. The fourth blocking cylinder 81 is located on the front side of the second buffer structure 22 away from the second conveying structure 12, and the fourth blocking cylinder 81 is driven to the fourth blocking block 82. The cylinder can drive the fourth blocking block 82 to rise and fall, so as to better block the goods.
[0060] In this embodiment, the connecting conveyor structure 13 includes multiple connecting conveyor belts 131 for receiving goods and multiple connecting electric rollers 132 for conveying goods towards the first conveyor structure 11 or the second conveyor structure 12. The multiple connecting conveyor belts 131 and multiple connecting electric rollers 132 are arranged alternately, with the left and right sides of the multiple connecting electric rollers 132 respectively connected to the right side of the first conveyor structure 11 and the left side of the second conveyor structure 12. The connecting electric rollers 132 are existing electric rollers, specifically existing drive devices that house the motor and reducer together inside the roller body. These electric rollers can select the direction of movement as needed, and the control of this direction of movement is existing technology. It is known that the connecting conveyor belts 131 can dock with the external upper-level conveyor structure 9 to receive goods. After the connecting conveyor belts 131 receive goods, the goods can be conveyed to the right side of the first conveyor structure 11 by rotating the multiple connecting electric rollers 132 to the left, or to the left side of the second conveyor structure 12 by rotating the multiple connecting electric rollers 132 to the right.
[0061] In this embodiment, a feed blocking member 133 is provided in the middle of the rear side of the primary buffer component 1 near the secondary buffer component 2, and the feed blocking member 133 corresponds to multiple connecting conveyor belts 131.
[0062] Furthermore, after a row of goods is cached on the secondary cache component of the caching mechanism, the goods can be pushed out by an external pushing structure to complete the placement of the goods. Specifically, the external pushing structure can be set above the caching mechanism, lifting and pushing the goods above it; or it can be set between the primary and secondary cache components, with lifting cylinders at both ends to drive it to lift and move between the primary and secondary cache components, thus avoiding the transfer of goods from the primary cache component to the secondary cache component. Pushing cylinders can also be set at both ends to control the pushing structure to push the goods. Since the external pushing structure is not a structure protected by this application, and its implementation structure can also be existing technology, it will not be described in detail in this application.
[0063] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
