[0019] Any feature disclosed in this specification (including any appended claims and abstract), unless otherwise stated, may be replaced by other equivalent or similar features. In other words, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0021] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features being referred to. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of such features.

[0022] Example 1 like Figures 1 to 6 As shown, the present invention provides a technical solution: A multifunctional cigarette pack buffer device suitable for a packaging unit, which at least includes but is not limited to an inlet portion 1, an outlet portion 2, a conveying portion 3, a temporary storage portion 4 and a power portion 5; the inlet portion 1 and the outlet portion 2 are respectively arranged on the front and rear sides of the conveying portion 3, the temporary storage portion 4 is movably arranged on at least one side of the conveying portion 3, and the power portion 5 is arranged on the conveying portion 3. The power portion 5 is capable of transporting the cigarette packs on the conveying portion 3 to the temporary storage portion 4.

[0023] Based on the above structure, when the rear end of the packaging unit needs to be repaired, the cache device is connected to the front end production line position of the packaging unit through the feed part 1 and the discharge part 2, so that the front end production line of the packaging unit can continue to perform packaging operations without stopping. The strip bags in the packaging process are transported to the temporary storage part 4 by the power part 5 for storage. When the rear end production line returns to normal, they are intermittently transmitted to the rear end packaging production line along with the normally transported strip bags; if the rear end production line maintenance time is too long, after the temporary storage part 4 is full, the storage cavity 42 filled with strip bags can also be taken out from the side wall of the conveying part 3 and replaced with an empty storage cavity 42 for temporary storage operations. The detachable temporary storage part 4 can make the entire cache device have a larger cache space.

[0024] As an example, the feeding part 1 may include a transport channel and a baffle plate 15; the transport channel may include a vertical channel 11 and a curved channel 12, the vertical channel 11 is connected to an external transport mechanism, the curved channel 12 is respectively connected to the vertical channel 11 and the conveying part, and the baffle plate 15 is provided on the vertical channel 11; Both the vertical channel 11 and the arc-shaped channel 12 include a supporting bottom plate 13 and a supporting side wall 14 ; the material blocking plate 15 is connected to the supporting side plate 422 of the vertical channel 11 .

[0025] Based on the above structure, the feeding part 1 is connected to the external conveying structure, and a baffle plate 15 is provided in the vertical direction to prevent the strips from falling out of the channel, thereby ensuring the safety and stability of the entire feeding process.

[0026] As an example, the discharge section 2 is arranged at the end position of the conveying section 3, and the discharge section 2 can be a conveyor belt structure, and the width of the discharge section 2 matches the width of the strip bag; the conveying direction of the feed section 1 is the same as the width direction of the strip bag, and the conveying direction of the discharge section 2 is the same as the length direction of the strip bag.

[0027] Based on the above structure, by transporting the feed part 1 in the direction of the width of the strip bag, the strip bags can be arranged in the width direction. More strip bags can be placed in the unit area, which is convenient for the overall transportation of the power part 5. At the same time, the discharge part 2 is transported in the direction of the length of the strip bag, so that each strip bag can be separated, which is convenient for other subsequent operations.

[0028] As an example, the conveying part may include a support frame 31, a transmission component 32 and a limiting component 33; the transmission component 32 is arranged at the center position of the support frame 31, and the limiting component 33 is arranged at the end of the transmission component 32, and the limiting component 33 can block the discharge part 2 of the transmission component 32 by moving.

[0029] Based on the above structure, the strip packages transmitted from the upstream are transmitted outward through the transmission component 32. When the rear end is maintained, the limiting component 33 is activated, so that the strip packages are gradually blocked and stay on the transmission component 32. When the predetermined number is reached, the power unit 5 is activated to transport the predetermined number of strip packages to the temporary storage unit 4 for storage.

[0030] As an example, the transmission component 32 may include a power motor 321, a transmission belt 322, a support bar 323 and a transmission wheel 324, the transmission wheels 324 are respectively arranged on both sides of the support bar 323, and the transmission belt 322 is arranged between the transmission wheel 324 and the support bar 323; the power motor 321 is arranged at the bottom position of the support bar 323, and the output part of the power motor 321 is connected to the transmission belt 322 through a pulley.

[0031] Based on the above structure, the conveyor belt 322 can be moved under the drive of the power motor 321, and finally the strip packages on it are transported. The power motor 321 is set at the bottom of the support bar 323 in order to reserve holes at the front and rear ends of the support bar 323. On the one hand, it can make the overall structure more compact, and on the other hand, it reserves assembly space for the limit component 33.

[0032] As an example, the limiting assembly 33 may include a limiting cylinder 331, a limiting plate 332 and a support plate 333, the support plate 333 is connected to the support frame 31, the cylinder body of the limiting cylinder 331 is fixedly set on the support plate 333, and the output part of the limiting cylinder 331 is connected to the limiting plate 332; the position of the limiting plate 332 is matched with the center position of the transmission assembly 32.

[0033] Based on the above structure, when the bag needs to be blocked, the limiting cylinder 331 is activated, so that the support plate 333 is driven by the piston rod to protrude from the plane where the conveyor belt 322 is located, thereby blocking the bag.

[0034] As an example, the temporary storage portion 4 may include a transfer trolley 41 and a storage chamber 42; the storage chamber 42 is hinged to the transfer trolley 41, and an adjustment member for adjusting the pitch angle of the storage chamber 42 is further provided on the transfer trolley 41; Based on the above structure, the pitch angle of the storage cavity 42 is adjusted by the adjusting part, which is convenient for the transportation of the storage cavity 42; when the storage cavity 42 needs to cooperate with the power unit to store the bar bags, the storage cavity 42 is adjusted to a vertical state through the adjusting part, which is convenient for cooperating with the vertical lifting power unit to complete the batch transfer operation of the bar bags. When the storage cavity 42 full of bar bags needs to be transported, the storage cavity 42 is adjusted to a pitch state through the adjusting part to avoid the storage cavity 42 falling from the open hinged seat during transportation.

[0035] As an example, the transfer trolley 41 may include an armrest 411 and a sliding base 412; a hinged ear is provided at the front end of the sliding base 412, and the armrest 411 is provided at the rear end of the sliding base 412; The storage cavity 42 may include a support base 421, support side panels 422, and a support back panel 423; the support base 421 is connected to the hinged ears, and the support side panels 422 and the support back panel 423 are enclosed on the support base 421 to form an open structure; A sliding block 424 and a guide rail 425 are provided on the support back plate 423, and the sliding block 424 is movably provided on the guide rail 425. A connecting seat 416 and a rotating block 426 are provided on the sliding block 424, and the rotating block 426 is hinged to the connecting seat 416; a rotating bearing 427 is provided at the center position of the rotating block 426; a rotating handrail wheel 413, a screw rod 414 and a fixed plate 415 are provided on the handrail frame 411; a threaded hole cooperating with the screw rod 414 is provided in the fixed plate 415, and the ends of the screw rod 414 are respectively connected to the rotating bearing 427 and the rotating handrail wheel 413.

[0036] Based on the above structure, by rotating the handrail wheel 413, the depth of the screw rod 414 screwed in and out of the fixed plate 415 can be adjusted, thereby realizing the adjustment of the pitch degree of the storage cavity 42. At the same time, through the cooperation of the sliding block 424 and the guide rail 425, different positions can be selected for support according to the different centers of gravity of the storage cavity 42 carried, thereby ensuring the stability of the support.

[0037] As an example, the power unit may include a linear module 51, a lifting cylinder 52 and a suction cup assembly 53; the linear module 51 is arranged at the upper end of the support frame 31, and the lifting cylinder 52 is movably arranged on the sliding plate 54 of the linear module 51; the suction cup assembly 53 is arranged at the output part of the lifting cylinder 52.

[0038] Based on the above structure, the sliding plate 54 can be moved along the length of the linear module 51 through the linear module 51, thereby driving the lifting cylinder 52 and the suction cup assembly 53 to move, and then cooperating with the suction cup assembly 53 and the lifting cylinder 52 to realize the transfer of batch strips on the left and right sides of the transport assembly. The linear module 51 in this solution is the existing technology, and this solution has not improved it, so it will not be repeated here.

[0039] As an example, the suction cup assembly 53 can include a transfer bracket 531, a suction cup component 532 and a control valve 533; the transfer bracket 531 is connected to the output of the lifting cylinder 52, the suction cup component 532 is set to multiple in the length direction of the transfer bracket 531, and the control valve 533 is connected to each suction cup component 532.

[0040] Based on the above structure, multiple suction cup components 532 can be supported by the transfer bracket 531, so that multiple strip packages can be transferred in batches simultaneously during transfer. The control valve 533 is individually connected to each suction cup component 532, which is convenient for releasing the strip packages one by one when they are transported back to the conveying part later, avoiding the accumulation of strip packages and causing blockage in the transportation channel.

[0041] Example 2 like Figures 1 to 4 As shown, the present invention provides a technical solution: A multifunctional cigarette pack caching method applicable to a packaging unit, comprising the following steps: Step 1: Choose whether to perform buffering according to the on-site situation. If buffering is required, start the limit component 33 to block the packet; if buffering is not required, transmit in sequence; The specific method of starting the limiting assembly 33 to block the strip package is to start the limiting cylinder 331 so that the support plate 333 protrudes from the plane where the conveyor belt 322 is located under the drive of the piston rod to block the strip package.

[0042] In step 2, when the number of blocked bag packs reaches a predetermined number, the lifting assembly lifts the suction cup assembly 53 as a whole to absorb the predetermined number of bag packs as a whole; the linear module 51 then transports the suction cup assembly 53 as a whole to the location of the storage cavity 42, releases the bag packs, and allows them to fall into the storage cavity 42 for temporary storage. The suction cup assembly 53 then returns to its original position to carry out the next transfer operation; this continues until the storage cavity 42 is full or the buffering operation is completed. Step three, when the buffering operation is completed; the suction cup assembly 53 transports the strip packages back to the top of the conveyor belt 322 in batches, and releases the strip packages on the single suction cup assembly 532 in sequence according to the time interval of the current normal sequence of strip package transmission; until the strip packages on the current suction cup assembly 53 are released, the strip packages are adsorbed in batches again until all the buffered strip packages are released to the assembly line.

[0043] In this solution, when releasing the bar pack, the bar pack on each suction cup member 532 is released individually through the control valve 533 to avoid interference with the normally transmitted bar pack.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
