Description

Technical Field

[0001] The utility model relates to the technical field of tobacco logistics auxiliary devices, in particular to a safety warning device used for cigarette palletizing. Background Art

[0002] At present, the last link of cigarette sorting in the cigarette logistics center is to stack the wrapped cigarettes on the pallet in packs. After the whole pallet is stacked, the operator changes the pallet and drags it to the shipping temporary storage area with a manual hydraulic forklift for placement. In the process of cigarette stacking, due to the excessive height of the stacked cigarettes, the stacked cigarettes often collapse and injure people and damage the cigarettes. Although on-site operation specifications are set, in actual work, the height of the stacked cigarettes can only be controlled by human visual senses, and the phenomenon of cigarettes collapsing due to excessive height still occurs. Therefore, it is further stipulated that the stacking of cigarettes per pallet shall not exceed 60 packs to control the excessive height. However, this method cannot effectively control the stacking height because the stacking of cigarettes is affected by factors such as order structure, irregular external dimensions of cigarette strips, and machines. This is also the technical problem to be solved by this application. Utility Model Content

[0017] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments:

[0018] Example:

[0019] Reference Figure 1The present embodiment provides a safety warning device for cigarette stacking; it comprises a cigarette labeling machine 1; a cigarette stacking area 2 is arranged near the exit side of the cigarette labeling machine 1; a height sensor 3 is installed on the exit side frame of the cigarette labeling machine 1; the sensing end of the height sensor 3 is arranged facing the cigarette stacking area 3, and the height sensor 3 is used to detect the working height of the cigarette stacking area 2; the height sensor 2 is connected to a controller 4 through a wire; the controller 4 is connected to an alarm 5 through a wire.

[0020] It also includes a positioning sensor 6 arranged at the cigarette stacking area 2; the positioning sensor 6 is used to detect whether there is a tray working in the cigarette stacking area 2, and the positioning sensor 6 is connected to the controller 4 through a wire.

[0021] The controller 4 is a time relay, and there are two controllers 4, which are respectively used to respond to the output signals of the height sensor 3 and the positioning sensor 6. The rated voltage of the time relay used in this embodiment is 24V; the electric shock form is two open and two closed; the action time is 20ms; and the electric shock material is silver.

[0022] Relays are used as controllers because of their low cost and easy installation, but their wiring is relatively complicated. In some cases where the wiring environment is poor, PLC or single-chip microcomputer control can also be considered.

[0023] The outlet side frame of the cigarette labeling machine 1 includes a vertical door-type structure, and the height sensor 3 and the alarm 5 are both installed on the upper side of the door-type structure; the height sensor 3 is a diffuse reflection electronic sensor; and the alarm 5 is an audible and visual alarm. In this embodiment, the height sensor 3 is an M18 diffuse reflection infrared sensor, and its detection distance is 3 meters + 10% adjustable; the output mode is PNP normally closed; the working voltage is 10-30VDC; the response time is 2ms; the alarm is a small strobe warning light; its light source type is LED strobe; the color is yellow; the power is ≤5W; the sound level is about 85 decibels; the voltage is 0-24V.

[0024] The diffuse reflection sensor is used because its transmitting end and receiving end are integrated, which is easy to adjust and install; it is understandable that the through-beam and mirror reflection sensors can be selected according to the actual work needs. At the same time, the height sensor is installed above the frame of the cigarette labeling machine to facilitate its wiring, reduce the difficulty of installation, and facilitate later maintenance and adjustment; in some environments that do not meet the installation requirements, the height sensor can be installed on the inner top surface of the house.

[0025] It also includes a DC transformer 7 connected to an external power source; the height sensor 3, the controller 4, the alarm 5 and the positioning sensor 6 are all powered by the DC transformer 7. The rated power of the DC transformer is 50W; the input voltage is 120V; and the output voltage is 24V.

[0026] An air switch 8 is also provided on the output wire of the DC transformer 7; the DC transformer 7 and the controller 4 are both provided in the electric control cabinet of the cigarette labeling machine 1. Conventionally, a new electrical system needs to design an independent electric control cabinet, but in order to save costs and ensure the cleanliness of the site, in this embodiment, since the added electrical equipment is relatively small, the electric control cabinet of the existing labeling machine can be used.

[0027] The manifestation of economic benefits:

[0028] After statistics on the sorting and stacking data of cigarettes from June to July 2023, the applicant learned that: a total of 3,755,436 cigarettes were sorted during the two-month effectiveness verification period, the number of pallets to be stacked was 2,504, the number of cigarette stacking over-high alarms was 2,504, the over-high stacking detection alarm rate was 100%, the number of collapses of over-high stacked cigarettes was 0, the number of major risks was 0, and the number of damaged cigarettes was 0.

[0029] After the device was implemented, there was no more collapse of stacked cigarettes causing damage to cigarettes, so the economic loss can be reduced by more than 5,000 yuan each year. The calculation method is: saving loss cost = number of collapsed damaged cigarettes from 1 to 3 months before the activity ÷ total number of sorted cigarettes from 1 to 3 months × annual sales × average half price of a single cigarette. The calculation results are as follows:

[0030] M = 22 pieces ÷ 11,529,149 pieces × 114,000 boxes × 250 pieces / box × 200 yuan / piece ÷ 2

[0031] =22÷11529149×114000×250×200÷2=5438 yuan.

[0032] If the device in this embodiment is not used, if the cigarette stack collapses, the operator will spend about 4 minutes to sort it out and resume production, so the sorting efficiency of the sorting equipment is improved by 8.7%. The calculation method is: efficiency improvement value = (average sorting efficiency of sorting equipment after the activity - average sorting efficiency of sorting equipment before the activity) ÷ average sorting efficiency of sorting equipment before the activity × 100%. The calculation results are as follows:

[0033] Efficiency increase △S = (M2-M1)÷M1×100%=(12500-11500)÷11500×100%

[0034] =8.7%.
