Technical Field
The invention relates to a front-back separation type cigarette storage channel translation detection device and a translation control method, and belongs to the technical field of cigarette packet packaging.
Background
Cigarette packaging is a very important process in cigarette production, and for a number of reasons, the packets on the packaging conveyor belt are temporarily stored by a packet buffer device, and are stored in a cigarette storage box again by a cigarette storage grid. The cigarette storage grille is provided with a plurality of cigarette storage channels, each cigarette storage channel can store N cigarettes at most, the sum of the lengths of the N cigarettes is generally larger than the length of the cigarette storage channel, when cigarettes are stored, each cigarette storage grille is moved by one lattice, and cigarettes stored in the next cigarette storage channel are sequentially repeated until the last cigarette storage channel is full of cigarettes.
A small section of gap is reserved between the tail outlet of the smoke inlet runway and the inlet of the smoke storage channel on the conveyor belt, and the small section of gap is called as the smoke storage channel allowance. Because most of the cigarette packets on the conveyor belt are discontinuous, only when the head of the Nth cigarette packet completely enters the cigarette storage channel in the cigarette storage process, the tail of the Nth cigarette packet does not exceed the allowance of the cigarette storage channel, the cigarette storage channel can move to the side, otherwise, the outlet at the tail of the cigarette inlet runway can be caused to clamp the Nth cigarette packet, and the cigarette storage channel is stopped due to faults.
In actual production practice, it is difficult to judge that the tail of the Nth pack in the cigarette storage channel does not exceed the remaining amount of the cigarette storage channel in the cigarette storage process, and the Nth pack may rebound after completely entering the cigarette storage channel, which can cause the cigarette inlet runway to clamp the Nth pack. However, the remaining amount of the cigarette storage channel between the inlet of the cigarette storage channel and the tail outlet of the cigarette inlet runway is usually very small, and under the limitation of the structural space, it is difficult to install a detection device such as a sensor for detecting whether the cigarette packet is jammed or not.

the frame is also provided with a second tobacco packet detection sensor and a third tobacco packet detection sensor, and the second tobacco packet detection sensor and the third tobacco packet detection sensor are used for detecting whether a tobacco packet exists at the corresponding tobacco inlet runway or not; the distance between the second tobacco bale detection sensor and the inlet of the tobacco storage channel is greater than or equal to M x L, the distance between the third tobacco bale detection sensor and the tail outlet of the tobacco inlet runway is less than or equal to M x L, and the second tobacco bale detection sensor is closer to the tobacco storage channel than the third tobacco bale detection sensor.

Example III
The present embodiment is a translation control method for applying the smoke storage channel translation detection device described in the first embodiment or the second embodiment, including the following steps:
and step one, receiving a full smoke signal sent by the smoke storage channel, and executing step two after receiving the full smoke signal. The cigarette storing channel is provided with a sensor for detecting the full of cigarettes, and when the cigarette pack of the cigarette storing channel is full of cigarettes, a full-cigarette signal is sent out.
Step two, the first tobacco bale detection sensor detects whether a tobacco bale exists at a position corresponding to a tobacco inlet runway; when all the first tobacco bale detection sensors detect tobacco bales, stopping transmission work of the tobacco inlet runway, and judging whether the tail of an M-th tobacco bale is in a safe area after performing tobacco bale separation action in the third step; otherwise, after the smoke inlet runway continues to transmit the smoke packets for a first preset time period (for example, the smoke inlet runway can be set to be 1 second), the second step is repeatedly executed so as to ensure that each first smoke packet detection sensor can detect the smoke packets.
Step three, the tobacco bale separating device acts, the separating mechanism drives the tobacco bale holding mechanism to drive the tobacco bale at the corresponding position on the tobacco inlet runway to move in the direction away from the tobacco storage channel, and the moving distance is greater than or equal to (S+D-N x L), so that the M+1th tobacco bale can not be interfered when the tail part of the M th tobacco bale is detected to be in a safe area; and then the second tobacco bale detection sensor and the third tobacco bale detection sensor detect whether the tobacco bale exists on the tobacco inlet runway corresponding to the position.
If the second tobacco bale detection sensor detects a tobacco bale, the third tobacco bale detection sensor does not detect the tobacco bale, at the moment, the tail of the Mth tobacco bale is in a safe area, and the fact that the Nth tobacco bale on the tobacco storage channel cannot block tobacco is indirectly indicated, so that the tobacco storage channel is driven to translate, and after the tobacco storage channel translates in place, the fourth step is executed.
Otherwise, after the smoke inlet runway continues to transmit the smoke packets for a second preset time period (for example, the smoke inlet runway can be set to be 1 second), the third step is repeatedly executed. Here, there are two cases: if the third tobacco bale detecting sensor detects a tobacco bale, the tail of the Mth tobacco bale is not in a safe area, and the situation that the Nth tobacco bale on the tobacco storage channel possibly clamps tobacco is indirectly judged, so that the tobacco bale separating device is reset, and after the tobacco bale is continuously transmitted by the tobacco bale feeding runway for a second preset time period (for example, the tobacco bale feeding runway can be set to be 1 second), the step three is repeatedly executed; or if the second tobacco bale detecting sensor and the third tobacco bale detecting sensor do not detect tobacco bales, whether the Nth tobacco bale on the tobacco storage channel can block cigarettes cannot be judged at the moment, so that the tobacco bale separating device is reset, and the tobacco charging runway is enabled to continuously transmit the tobacco bales for a second preset time period (for example, the second time period can be set to be 1 second), and then the third step is repeatedly executed.
And fourthly, continuously transmitting the cigarette packets by the cigarette feeding runway, and returning to the first step.
The present invention is not limited to the specific technical solutions described in the above embodiments, and other embodiments may be provided in addition to the above embodiments. Any modifications, equivalent substitutions, improvements, etc. made by those skilled in the art, which are within the spirit and principles of the present invention, are intended to be included within the scope of the present invention.
