Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production, in particular to a cartridge buffer device with adjustable storage capacity. Background Art

[0002] The strip box conveying system currently used in the market is connected to the packaging machine outlet at the front end and the carton filling and sealing system at the back end. The strip box conveying system consists of strip box lifting equipment directly connected to the packaging machine outlet, strip box missing package detection equipment, strip box overhead conveying equipment, strip box diversion equipment, strip box vertical descending equipment, strip box reversing collection equipment, strip box appearance detection equipment and strip box storage equipment at the front end of the carton filling and sealing system. The strip boxes produced by the packaging machine are transported to the entrance of the carton filling and sealing machine through the strip box conveying system, and the strip boxes are packed, sealed, and coded. The strip boxes from the packaging machine outlet to the carton filling and sealing system belong to the assembly line operation mode. The disadvantage of the assembly line operation mode is that as long as there is an abnormal situation in any intermediate link that causes it to fail to work normally, the entire assembly line will be paralyzed.

[0003] The buffer device is an important part of the box conveying system. It solves the problem of the whole process line or back-end equipment being shut down due to a small and easy-to-handle fault in the box conveying system, and ensures that the normal production of other locations is not affected when a small fault occurs in the whole line. The storage space of the existing buffer device is generally fixed, and the storage capacity cannot be adjusted. When faced with some faults that require a long time to handle, due to the limitation of buffer capacity, it is easy to cause congestion at the outlet of the packaging machine or lack of material in the box conveying system.

[0042] Embodiment 1:

[0043] Please refer to Figure 1-8 , this embodiment provides a bar box buffer device with adjustable storage capacity, including a support frame 100 and a conveying assembly 200, a transfer mechanism 300 and a first storage cabinet assembly 400 installed on the support frame 100;

[0044] The support frame 100 is a box structure composed of a number of square tubes and sealing plates, which has a certain load-bearing capacity and protection capability, and provides a supporting connection function and an installation basis for various components. Specifically, an installation cavity for installing various components is formed at the top of the support frame 100, a storage cavity for storing strip boxes is formed at the bottom, and a control cabinet 700 for installing an integrated control system is arranged on the side.

[0045] The conveying assembly 200 is disposed in the support frame 100 and is used to transport the strip boxes; the conveying assembly 200 has a feed port 211 and a discharge port 222, the feed port 211 is used to dock with an upstream machine, and the discharge port 222 is used to dock with a downstream machine;

[0046] The transfer mechanism 300 is used to transfer the strip box between the conveying assembly 200 and the first storage cabinet assembly 400;

[0047] The first storage cabinet assembly 400 is arranged below the conveying assembly 200, and the storage cabinet assembly includes a lifting mechanism 410 and a moving trolley 420; the lifting mechanism 410 is used to store the strip boxes, and the lifting mechanism 410 is slidably connected to the support frame 100, and the lifting mechanism 410 can move back and forth in the gravity direction relative to the support frame 100; the moving trolley 420 is arranged at the bottom of the lifting mechanism 410, and the moving trolley 420 has a receiving plate 421 for receiving the strip boxes; by transferring the strip boxes between the receiving plate 421 and the lifting mechanism 410, the strip boxes can be replenished or removed.

[0048] When in use, when the system operates normally, the strip box is fed in by the upstream machine, and the strip box is fed to the discharge port 222 through the feed port 211 of the conveying assembly 200, and then the downstream machine performs the next process; when the front-end equipment fails, the upstream machine cannot normally input the strip box, and the strip box stored in the strip box buffer device is released to maintain the normal operation of the system; when the back-end equipment fails, the downstream machine cannot process the strip box in time, and the strip box is stored in the strip box buffer device to maintain the normal operation of the system;

[0049] The strip box caching device of this embodiment provides the conveying and caching functions of the strip boxes by setting up a conveying component 200. The strip boxes on the conveying component 200 are grabbed by the transfer mechanism 300 and transferred to the lifting mechanism 410. Every time the lifting mechanism 410 stores a full layer of strip boxes, it moves down by the thickness of a strip box to store the next layer of strip boxes. When the strip boxes on the lifting mechanism 410 are full to the preset number of layers, the preset number of layers in this embodiment is 20 layers, the lifting mechanism 410 descends and transfers the 20 full layers of strip boxes into the mobile cart 420, thereby emptying the strip boxes on the lifting mechanism 410 to facilitate the storage of the next layer of strip boxes; the mobile cart 420 has a receiving plate 421 for receiving the strip boxes; the mobile cart 420 moves the receiving plate 421 filled with strip boxes out of this strip box caching device, thereby expanding the storage capacity of this strip box caching device and avoiding affecting the overall operation of the system due to insufficient storage. On the contrary, it is the process of releasing the strip boxes. The strip boxes on the lifting mechanism 410 are grabbed by the transfer mechanism 300 and transferred to the conveying assembly 200 to complete the release of a layer of strip boxes. Each time a layer of strip boxes is released, the lifting mechanism 410 moves up by the thickness of a strip box to raise the next layer of strip boxes to the grabbing range of the transfer mechanism 300. When all the strip boxes on the lifting mechanism 410 are released, the lifting mechanism 410 is replenished by the mobile trolley 420 with the receiving plate 421 full of strip boxes, thereby improving the strip box caching capacity of the strip box caching device and avoiding the internal shortage of materials affecting the overall operation of the system. The problem of the existing strip box conveying system causing the entire process line to shut down or the back-end equipment to shut down due to small-scale and easy-to-handle faults is solved; the internal storage of the cache device is adjustable, and its cache capacity is controllable. In the case of blockage or shortage of materials due to faults at the front and back ends, the strip boxes are stored or released for adjustment, effectively maintaining the normal operation of the system and ensuring the normal production of the entire production line.

[0050] Specifically, the lifting mechanism 410 includes a first lifting plate 411, a second lifting plate 412, a connecting plate 413 and a first driving structure 414;

[0051] The first lifting plate 411 and the second lifting plate 412 are used to lift the two ends of the box respectively. The first lifting plate 411 and the second lifting plate 412 are arranged in parallel. A receiving gap 412 is formed between the first lifting plate 411 and the second lifting plate.
