Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packaging, in particular to a cigar supply device. Background Art

[0002] In existing automated production equipment, the wrapped cigarettes are generally transferred to a cigarette warehouse and quantitatively transported to a mold box through a cigarette feeding device.

[0003] For general thin cigarettes, as shown in the patent document with application number CN202323029022.4, the cigarette feeding device generally includes a plurality of vertically arranged lower cigarette partitions, and cigarette channels are formed between adjacent partitions. The cigarette channels have a size limit so that only one cigarette can pass through at a time. Cigarettes from different cigarette channels are arranged in groups and fed into the mold box to achieve cigarette packaging. The diameter, shape and packaging habits of cigar cigarettes are different from those of general thin cigarettes. In the existing process, some cigarette feeding devices use grooved drum wheels for conveying. The outer periphery of the grooved drum wheel is arranged with cigarette grooves that can cooperate with a single cigar. After the cigar is fed from the hopper above the drum wheel, it falls into the cigarette groove and moves with the rotation of the drum wheel. When the cigar rotates to the lower side of the grooved drum wheel, the cigar detaches from the cigarette groove and falls onto the receiving object below to achieve quantitative supply.

[0004] In order to make the cigars smoothly enter the cigarette slots of the grooved drum, a stirrer is usually set above the grooved drum. The stirrer includes a stirring roller with the same length as the cigars. When the stirring roller rotates, it stirs the cigars at the bottom of the hopper to facilitate the cigars to be loaded into the cigarette slots. Due to the large diameter and irregular shape of cigars, the cigars need to move with a large amplitude during the stirring process to easily match the cigarette slots. Because the single weight of cigars is large, the cigars at the bottom are under great pressure. During the movement of the cigars, it is easy to get stuck and squeezed with the grooved drum, which leads to deformation and damage of the cigarettes, increasing production costs. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a cigar supply device, which can quantitatively convey cigars, avoid deformation, breakage and other problems caused by cigar accumulation, and reduce the impact of defective products on production costs.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A cigar cigarette supply device includes a first feeding unit, a first transfer platform disposed below the first feeding unit, a second feeding unit connected to the end of the first transfer platform, and a second transfer platform disposed below the second feeding unit; a discharge port facing the first transfer platform is formed at the lower end of the first feeding unit; the second feeding unit includes a temporary storage bin in the upper half and a transfer bin in the lower half, the temporary storage bin is provided with a receiving port connected to the end of the first transfer platform, a cigarette sensor is disposed at a certain height position on the inner wall of the temporary storage bin, a rotatable metering drum is disposed inside the transfer bin, a plurality of cigarette slots are arranged on the outer periphery of the metering drum, a communicating inlet is formed at the connection between the temporary storage bin and the transfer bin, a discharge port facing the second transfer platform is formed at the lower end of the transfer bin, and a stirring roller is disposed above the inlet.

[0008] The present utility model supplies cigar cigarettes in a two-step feeding manner: the first step is completed by the first feeding unit and the first transfer platform. The first feeding unit is used to continuously receive cigar cigarettes and transfer the cigarettes to the first transfer platform through the discharge port. The first transfer platform horizontally transports the cigar cigarettes placed above in the direction of the second feeding unit through structures such as a conveyor belt. A stirring roller for stirring the cigar cigarettes is disposed above the discharge port. The second step is composed of the second feeding unit and the second transfer platform. The temporary storage bin in the upper half of the second feeding unit is used to receive and temporarily store the cigar cigarettes from the first transfer platform. The transfer bin in the lower half is used to individually transfer the cigar cigarettes in the temporary storage bin one by one and transfer them from the lower discharge port to the second transfer platform. Under the action of the metering drum in the transfer bin, the cigar cigarettes can be supplied to the second transfer platform quantitatively and uniformly, facilitating subsequent packaging processing. Since the present utility model is provided with two-step feeding and a cigarette sensor is disposed at a certain height position on the inner wall of the temporary storage bin, when the cigarettes in the temporary storage bin accumulate to a certain height, the cigarette sensor will be triggered, and then a signal will be sent to the background control system through the cigarette sensor. The background control system can pause the operation of the first transfer platform or reduce the operation speed of the first transfer platform to ensure that the temporary storage bin will not accumulate too many cigar cigarettes, thereby reducing the probability of defective products and lowering the production cost.

[0009] Further, the first feeding unit includes a guiding portion. The guiding portion includes a first guide plate relatively far from the second feeding unit and a second guide plate relatively close to the second feeding unit. A guiding channel with a gradually decreasing width from top to bottom is formed between the first guide plate and the second guide plate.

[0010] Further, the distance between the first guide plate and the first transfer platform is smaller than the distance between the second guide plate and the first transfer platform. A horizontal transfer port is formed between the lower end of the second guide plate and the first transfer platform.

[0011] Further, the temporary storage bin includes an inlet portion with a gradually decreasing width of the bin body from top to bottom.

[0012] Further, the inlet portion includes a first side plate near one side of the first transfer platform and a second side plate far from one side of the first transfer platform. The upper end of the first side plate is set at a height not exceeding that of the first transfer platform, and the upper end of the second side plate is higher than that of the first transfer platform.

[0013] Further, a vertically arranged storage baffle is connected to the upper end of the first side plate.

[0014] Further, the cigarette sensor is arranged at the height position where the first side plate is connected to the storage baffle.

[0015] Further, the second transfer platform includes a conveyor belt and a plurality of positioning blocks arranged on the outer side surface of the conveyor belt. The positioning blocks are provided with positioning receiving grooves.

[0016] Further, the cross section of the positioning receiving groove is not less than that of the cigarette card slot.

[0017] Further, an adsorption channel is provided at the bottom of the cigarette card slot.

[0018] In summary, the following beneficial effects can be achieved by applying the present utility model:

[0019] 1. The present utility model is provided with two-step feeding, and a cigarette sensor is arranged at a certain height position on the inner wall of the temporary storage bin. When the cigarettes in the temporary storage bin are stacked to a certain height, the cigarette sensor will be triggered, and then a signal will be sent to the background control system through the cigarette sensor. The background control system can pause the operation of the first transfer platform, ensuring that the temporary storage bin will not accumulate too many cigar cigarettes, thereby reducing the probability of defective products and lowering the production cost.

[0020] 2. The present utility model can control the operation state of the first transfer platform through the cigarette sensor. After adjusting the operation states of the quantitative hub and the second transfer platform, the first transfer platform can adaptively change the conveying speed to meet different production requirements.

[0021] 3. In some embodiments, the present utility model is further provided with an adsorption channel, which can prevent the cigarettes from rubbing against the inner wall of the transfer bin, thereby reducing the probability of defective products. Description of the Drawings

Detailed implementation mode

[0025] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0026] Refer to Figure 1 , an embodiment of the first aspect of the present invention provides a cigar cigarette supply device, which includes a first feeding unit 1, a first transfer platform 2 arranged below the first feeding unit, a second feeding unit 3 connected to the end of the first transfer platform, and a second transfer platform 4 arranged below the second feeding unit. The first feeding unit is used to continuously receive cigar cigarettes from the previous process module and transfer the cigar cigarettes to the first transfer platform. The first transfer platform is used to transfer the cigarettes above to the second feeding unit. The second feeding unit is used to gradually transfer the cigarettes to the second transfer platform in the form of single roots. The second transfer platform is used to receive the cigarettes one by one and arrange the cigarettes regularly.

[0027] The specific structures of the above-mentioned first feeding unit, first transfer platform, second feeding unit, and second transfer platform are as follows:

[0028] The first feeding unit 1 includes a diversion part located in the lower half. The lower end of the diversion part forms a discharge port facing the first transfer platform. The diversion part includes a first guide plate 11 relatively located upstream of the first transfer platform and a second guide plate 12 relatively located downstream of the first transfer platform. The distance between the first guide plate and the second guide plate gradually decreases from top to bottom, so that the discharge port has a conical structure, thereby restricting the discharge rate of the cigarettes. Moreover, the distance between the first guide plate and the first transfer platform is less than the diameter of the cigar cigarette, and the distance between the second guide plate and the first transfer platform is greater than the diameter of the cigar cigarette, so that the cigarette cannot slide out from the gap between the first guide plate and the first transfer platform and can only be horizontally conveyed to the side of the second guide plate;

[0029] The first transfer platform 2 includes a first conveyor belt and a first driving roller, and the working state of the driving roller is adjusted by a background control system;

[0030] The second feeding unit 3 includes a temporary storage bin 31 in the upper half and a transfer bin 32 in the lower half. The temporary storage bin 31 includes a first side plate 311 close to the first transfer platform and a second side plate 312 far from the first transfer platform. The upper end of the first transfer side plate does not exceed the upper surface of the first transfer platform, so that a receiving port is formed above the first transfer side plate, enabling the cigarette sticks on the first transfer platform to fall into the temporary storage bin after reaching the end. The upper end of the second transfer side plate exceeds the upper surface of the first transfer platform, and a vertically arranged storage baffle 313 is connected to the upper end of the second transfer side plate, preventing the cigarette sticks entering the temporary storage bin from falling out. The distance between the first side plate and the second side plate gradually decreases from top to bottom, and a cigarette inlet 314 is formed between the lower ends of the first side plate and the second side plate. A stirring roller 33 is provided on the upper side of the cigarette inlet. The length direction of the stirring roller is the same as the length direction of the cigarette stick, and is used to rotate the contacting cigarette sticks to facilitate subsequent transfer. The transfer bin 32 is in a cylindrical structure, and a quantitative drum 34 is arranged inside the transfer bin. Cigarette stick slots 341 that can cooperate with cigarette sticks are arranged on the outer circumference of the quantitative drum. Each cigarette stick slot can accommodate at most one cigar. Under the action of the stirring roller, each time the cigarette stick slot reaches below the cigarette inlet, one cigar enters the cigarette stick slot, thereby realizing quantitative conveying. An outlet 321 is provided at the lower end of the transfer bin. When the cigarette stick reaches the outlet, it disengages from the cigarette stick slot and falls onto the second transfer platform;

[0031] The second transfer platform 4 includes a second conveyor belt and a second driving roller. A plurality of positioning blocks 41 are installed on the outer belt surface of the second conveyor belt. The positioning blocks are provided with positioning receiving grooves 411 for receiving the cigarette sticks falling from the outlet. Under the action of the positioning blocks, the cigarette sticks are arranged regularly one by one, facilitating subsequent packaging.

[0032] In order to further reduce the probability of defective cigarette sticks, referring to Figure 2 , in some embodiments, an adsorption channel 342 is further communicated with the bottom of the cigarette stick slot 341 of the quantitative drum 34. The adsorption channel makes the cigarette stick 5 closely adhere to the cigarette stick slot by means of negative pressure adsorption, avoiding damage to the cigarette stick caused by friction between the cigarette stick and the inner wall of the transfer bin during the movement of the quantitative drum. The adsorption channels 342 converge to a main channel 343 in the middle of the quantitative drum, and the main channel is connected to a negative pressure device to achieve the adsorption effect. A sealing block 344 is attached to the inner wall of the main channel. When the adsorption channel rotates to a specific position, the sealing block blocks it and disconnects the connection with the main channel, causing the corresponding cigarette stick slot to lose the adsorption effect and facilitating the detachment of the cigarette stick.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
