Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette manufacturing, and particularly relates to a device for improving the running stability of a belt conveyor in a filter rod magazine. Background Art

[0002] At the forming end in a filter rod magazine of a cigarette factory, there are a forming-end belt conveyor, a tray loader, and a forming machine. At the discharging end, there are a discharging-end belt conveyor, a tray unloader, and a transmitter.

[0003] The forming machine is responsible for processing tobacco raw materials into filter rods; the tray loader is responsible for collecting and loading the formed filter rods onto trays; the forming-end belt conveyor includes a forming upper double-belt conveying device and a forming lower double-belt conveying device arranged on a forming-end rack, where the forming lower double-belt conveying device is below the forming upper double-belt conveying device; the forming upper double-belt conveying device includes forming upper belts arranged on both sides, and the two forming upper belts cooperate to convey empty filter rod trays in the storage area to one side of the tray loader; the forming lower double-belt conveying device includes forming lower belts arranged on both sides, and the two forming lower belts cooperate to convey loaded filter rod trays to one side of the storage area.

[0004] The tray unloader is responsible for taking out the filter rods from the loaded filter rod trays and placing them at the input end of the transmitter; the transmitter is responsible for accurately launching the filter rods into the cigarette making machine; the discharging-end belt conveyor includes a discharging upper double-belt conveying device and a discharging lower double-belt conveying device arranged on a discharging-end rack, where the discharging lower double-belt conveying device is below the discharging upper double-belt conveying device; the discharging upper double-belt conveying device includes discharging upper belts arranged on both sides, and the two discharging upper belts cooperate to convey loaded filter rod trays in the storage area to the tray unloader; the discharging lower double-belt conveying device includes discharging lower belts arranged on both sides, and the two discharging lower belts cooperate to convey the empty filter rod trays obtained after the filter rods are taken out by the tray unloader to one side of the storage area.

[0005] Among them, the forming-end belt conveyor serves as a bridge between the forming machine and the storage area, and the discharging-end belt conveyor serves as a bridge between the storage area and the transmitter. The forming-end belt conveyor and the discharging-end belt conveyor play a very important role in the overall operation of the filter rod magazine. However, during the conveying process, the filter rod tray group often has problems such as overall deviation and skew, resulting in production and process problems such as the filter rod tray group being unable to be conveyed normally, requiring a large amount of manual intervention, filter rod trays tipping over, and filter rods scattering.

[0006] Specifically, the main problem of the forming upper double-belt conveying device is the overall deviation of the empty filter rod tray group. One end of each empty filter rod tray falls on the guiding component on one side of one of the forming upper belts, and the other end of each empty filter rod tray rubs against the other forming upper belt, resulting in phenomena such as empty filter rod trays tipping over and abnormal wear of the forming upper belts.

[0007] Specifically, the main problems of the lower forming double-belt conveyor equipment are as follows: the full filter rod trays are skewed during transportation after being loaded onto the trays, affecting normal transportation; and the full filter rod trays are grouped in sets of 15. When the production reaches 15 full trays, the stacker will generate a transfer task to transfer the 15 full filter rod trays on the two lower forming belts to the storage area as a whole. However, when the number of full filter rod trays on the two lower forming belts has not reached the full set, the filter rod trays that have been transported to one end of the two lower forming belts are blocked by the baffles at one end of the lower forming double-belt conveyor equipment. The blocked filter rod trays rub against the lower forming belts. As the number of blocked filter rod trays increases, the resistance of the filter rod tray group will continuously intensify, resulting in problems such as the deviation and wear of the lower forming belts.

[0008] Specifically, the main problems of the upper launching double-belt conveyor equipment are as follows: the number of filter rod trays on the two upper launching belts is more than that on the two lower forming belts, and the resistance is stronger. Moreover, the whole filter rod tray group sent out from the storage area has an overall deviation, which is likely to cause disordered rods and affect the production of the transmitter. The reason for the larger number of filter rod trays on the two upper launching belts is that: the filter rod trays sent out from the storage area are grouped in sets of 15. When the unloader takes out the filter rods from several trays (such as 7 trays) of the filter rod trays, a material requirement task will be generated, and then there will be a phenomenon of 8 + 15 filter rod trays on the two upper launching belts.

[0009] Specifically, the main problems of the lower launching double-belt conveyor equipment are as follows: the attitude change of a single empty filter rod tray is large, which is likely to cause jamming and stagnation, and the integrity of the empty filter rod tray group is poor. Furthermore, it will affect the transportation of the empty filter rod tray group by the upper forming double-belt conveyor equipment. In addition, the empty filter rod trays are grouped in sets of 15. When the production reaches 15 full trays, the stacker will generate a transfer task to transfer the 15 empty filter rod trays on the two lower launching belts to the storage area as a whole. However, when the number of empty filter rod trays on the two lower launching belts has not reached the full set, the empty filter rod trays that have been transported to one end of the two lower launching belts are blocked by the baffles at one end of the lower launching double-belt conveyor equipment. The blocked empty filter rod trays rub against the lower launching belts. As the number of blocked empty filter rod trays increases, the resistance of the empty filter rod tray group will gradually increase, resulting in problems such as the deviation and wear of the lower launching belts.

The two first lifting assemblies on both sides cooperate to lift the filter rod full trays blocked and staying on the two forming lower belts to be separated from the forming lower belts.

[0017] Furthermore, the first lifting assembly includes a plurality of first lifting plates arranged side by side along the conveying direction of the corresponding side forming lower belt. Each first lifting plate is driven to lift vertically by a corresponding first lifting driving source. Each first lifting plate of one side first lifting assembly cooperates with the corresponding first lifting plate of the other side first lifting assembly and rises by the same height at the same time, and is used to lift the corresponding filter rod full trays blocked and staying on the two forming lower belts to be separated from the forming lower belts.

[0018] Further, it further includes a second lifting member and a pneumatic centering member. The second lifting member includes a second lifting assembly disposed outside each upper conveying belt for launching.

[0023] Further, the second lifting driving source is a cylinder.

In this way, the two fixed centering components cooperate to prevent the overall offset of the filter rod empty tray group, so that one end of each filter rod empty tray is located on one of the upper forming belts and the other end is located on the other upper forming belt, thereby preventing the filter rod empty tray from tipping over and the upper forming belt from wearing out. The first stop plate rises and is used to stop the filter rod solid tray that is tilted on the two lower forming belts, and the first stop plate descends and is used to allow the stopped filter rod solid tray to be conveyed by the two lower forming belts and pass over the first stop plate, thereby ensuring normal conveyance of the filter rod solid tray.

[0026] In this utility model, the device for improving the operational stability of the filter rod storage belt conveyor further includes a first lifting member, which comprises a first lifting assembly disposed on the outside of each lower forming belt.

Among them, the second aligning driving source is a cylinder.

[0049] In summary, through the device for improving the running stability of the filter rod magazine belt conveyor in the present utility model, the attitude of a single empty filter rod tray 7 on the lower conveyor belt 401 of the launcher is good, without skewing or deviation phenomena, the integrity of the empty filter rod tray group and the filter rod solid plate group is good, the conveyance is completely centered, and the forming end belt conveyor and the launching end belt conveyor operate stably, greatly reducing belt wear, and can reduce the degree of personnel intervention and labor intensity, effectively improving the overall running smoothness and stability of the filter rod magazine.
