Abstract

The utility model discloses a fault detection device of cigarette machine spider claw, including a plurality of spider claws, the spider claw sets up in a cigarette pipeline top, it is peripheral that all spider claws encircle the carousel of installing in a vertical setting, and the carousel is installed in first pivot, and it changes shaft encoder to be equipped with in the first pivot, receiving the drum and being located carousel the place ahead, the second pivot of receiving the drum place is parallel with the carousel, be equipped with a plurality of induced draft grooves parallel with the second pivot on the outer circumference of receipt drum, line source sensor settings is receiving the drum top, and the detection position of line source sensor is just to the groove of induced drafting. The utility model discloses a detect the cigarette and prop up the displacement and a cigarette damage condition in spider claw data send process, carry out quick fault detection and location to spider claw spare to improve the fault detection rate of accuracy.

Description

The failure detector of cigarette machine spider pawl

Technical field

The utility model belongs to tobacco production equipment technical field, the particularly failure detector of cigarette machine spider pawl.

Background technology

PROTOS cigarette machine is one of production of cigarettes equipment of domestic main flow. The semi-finished product cigarette being rolled into by SE cigarette machine forms the cigarette of normal length after cutter head cutting, and cigarette is sent to cigarette on the air draught groove that receives drum by 8 spider pawls. After certain spider pawl breaks down, corresponding cigarette can not correctly be transported to and receive on drum, cause cigarette align-err or loss and cause shutdown. Because spider pawl running speed is high, in the time that breaking down, certain spider pawl is difficult to it to locate fast, conventionally can only by virtue of experience investigate one by one to eliminate fault to spider pawl, cause that maintenance time is long, percent defective is high, waste of raw materials is serious.

Summary of the invention

The purpose of this utility model is in order to address the above problem, and provides a kind of and can pass through to detect displacement and the cigarette degree of impairment of cigarette, and spider pawl is carried out to the failure detector of the cigarette machine spider pawl of quick fault testing and location.

For this reason, the technical solution of the utility model is: the failure detector of cigarette machine spider pawl, comprise some spider pawls, and spider pawl is arranged on cigarette conveyance conduit top; All spider dog collars are around being arranged on a rotating disk periphery vertically arranging, and rotating disk is arranged in the first rotating shaft, and the first rotating shaft is provided with shaft encoder; Receive drum and be positioned at rotating disk front, the second rotating shaft that receives drum place is parallel with rotating disk; The excircle that receives drum is provided with some and air draught groove the second shaft parallel; Line source sensor setting is above reception drum, and the detection position of line source sensor is just to air draught groove.

When the utility model work, the cigarette of well cutting is transported to spider pawl below by cigarette conveyance conduit, and rotating disk is driven by the first rotating shaft, makes to clockwise rotate after spider pawl crawl cigarette, makes next spider pawl can continue to capture cigarette; Spider pawl is put into the cigarette of crawl to receive the air draught groove of drum and rotate with receiving drum, in the time that cigarette runs to the detection position of line source sensor, whether line source sensor detects the position of cigarette on air draught groove correct, if occur and occur continuously repeatedly problem, determine fault spider pawl position by the shaft encoder in the first rotating shaft and the PLC control device that is attached thereto. The utility model is by detecting displacement and the cigarette degree of impairment of cigarette in spider pawl transport process, spider tine is carried out to quick fault testing and location, thereby reach and reduce maintenance time, improve fault detect accuracy rate, and the cigarette quantity of wasting in minimizing maintenance process, raw material resources avoids waste.

Brief description of the drawings

Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is work schematic diagram of the present utility model.

Fig. 3 is work block diagram of the present utility model.

In figure, be labeled as: spider pawl 1, cigarette conveyance conduit 2, rotating disk 3, the first rotating shaft 4, shaft encoder 5, the cigarette 91 that receives drum 6, air draught groove 61, the second rotating shaft 7, line source sensor 8, cigarette 9, goes wrong.

Detailed description of the invention

Referring to accompanying drawing. The present embodiment comprises some spider pawls 1, and spider pawl is arranged on cigarette conveyance conduit 2 tops; All spider dog collars are around being arranged on rotating disk 3 peripheries that vertically arrange, and rotating disk is arranged in the first rotating shaft 4, and the first rotating shaft is provided with shaft encoder 5; Receive drum 6 and be positioned at rotating disk front, the second rotating shaft 7 that receives drum place is parallel with rotating disk; The excircle that receives drum is provided with some and air draught groove 61 the second shaft parallel; Line source sensor 8 is arranged on and receives drum top, and the detection position of line source sensor is just to air draught groove.

When the present embodiment work, semi-finished product cigarette enters 2, the first rotating shafts 4 of cigarette conveyance conduit and drives rotating disk 3 to rotate after cutterhead cutting, and the second rotating shaft 7 drives reception drum 6 to rotate; After the spider pawl 1 of cigarette conveyance conduit top captures cigarette 9, clockwise rotate, make next spider pawl can continue to capture cigarette; Meanwhile, capture the spider pawl of cigarette clockwise rotate with receive drum on air draught groove 61 positions when relative, spider pawl is put into cigarette 9 the air draught groove that receives drum, cigarette is followed the next procedure that rotates into that receives drum; In the time that cigarette runs to the detection position of line source sensor 8, whether line source sensor detects the position of cigarette on air draught groove correct. Under normal circumstances, after spider pawl transmits, cigarette front and back skew in the air draught groove that receives drum can not exceed 3mm, and cigarette losing probability is less than 0.01 ‰. If cigarette skew is greater than 5mm or cigarette is lost, illustrate that certain spider pawl breaks down, PLC control device will record the wrong data of the corresponding spider pawl of these cigarette 91 place air draught grooves that go wrong. In the time that certain spider pawl occurs continuously transmitting mistake or error accumulation number and far exceedes mean value, there is fault by this spider pawl of judgement in diagnostic device, and carries out fault demonstration on man-machine dialog interface.

The present embodiment is the run location that guarantees accurately to locate spider pawl 1 and cigarette 9 in high-speed cruising, shaft encoder 5 is connected in the first rotating shaft 4 of spider pawl 1, determine the run location of filter stick on forming machine by " the equipment operation phase calculation " unit in PLC control device, when operating in, cigarette 9 when line source sensor detects 8 detection position, carries out the collection of cigarette offset data and calculating, and judge this cigarette is by which spider pawl transmission, and then judge whether this spider pawl exists fault.

The fault diagnosis of the present embodiment to spider pawl, single spider pawl fault diagnosis and be less than 20 minutes maintenance time, fault diagnosis accuracy rate is greater than 98%; The cigarette quantity of maintenance process waste is less than 500, reduces by 93.8%. 18 cover cigarette machines reduce 262500 of cigarette wastes every year, reduce by 3500 minutes downtimes of breakdown maintenance, can create direct economic effect indirect economic effect more than 1,500,000 yuan.
