Detailed Description

The technical solution provided by the present invention is explained in more detail with reference to fig. 1 to 4.

Referring to fig. 1 to 4, an embodiment of the present invention provides a cigarette conveying device, which includes a conveying passage 1, a flow guide member 2, a detection member 3, and a buffer member 4. The conveying channel 1 comprises a first channel 11 and a second channel 12, wherein the first channel 11 is communicated with the second channel 12, and a corner 13 is arranged at the joint of the first channel 11 and the second channel 12. The flow guide 2 is installed at the corner 13 of the first and

second passages

11 and 12 and makes the first and

second passages

11 and 12 smoothly transited. The flow guide 2 is configured to be deformable in the conveying direction a of the first passage 11. The detection means 3 are arranged outside the flow guide 2 and the detection means 3 are configured to trigger the machine for feeding the cigarettes 10 to the first channel 11 to be stopped when a deformation of the flow guide 2 is detected. The damping part 4 is at least partly located between the flow guide 2 and the detection part 3. The buffer member 4 is configured to buffer the air guide 2 before the air guide 2 touches the detection member 3.

The detection component 3 is used for detecting whether the diversion part 2 deforms or not. If the air guide 2 deforms, the air guide 2 touches the buffer part 4 first and then touches the detection part 3. The buffer member 4 serves to reduce or even prevent the flow guide 2 from deforming too fast, thereby striking or damaging the detection member 3.

If the flow guide 2 is deformed, it indicates that the cigarettes 10 in the first and

second passages

11, 12 are blocked. The cigarettes 10 cannot be smoothly transported downstream, so the cigarettes 10 may press the flow guide member 2, thereby causing the flow guide member 2 to deform. The deflection of the flow guide piece 2 is small, the deflection is smaller than the diameter of the cigarette 10, and after the cigarette 10 cannot be deformed from the flow guide piece 2, the flow guide piece 2 leaks out or falls off from a gap between the first channel 11 and the second channel 12.

When the detection component 3 detects that the diversion element 2 is deformed, the detection component 3 triggers the shutdown of the upstream equipment for conveying the cigarettes 10 to the conveying channel 1, such as a tray loader, a tray unloader and the like.

In some embodiments, the cigarette conveying device further comprises an alarm device (not shown) electrically connected to the detection unit 3, the alarm device being configured to activate the alarm device to send an alarm signal when the detection unit 3 detects a cigarette 10 being jammed. The alarm device is, for example, an alarm lamp, an alarm, an electronic display screen, etc. When the cigarette 10 in the channel is dujammed, the alarm device is started, and then alarm information such as sound, sound and light, character display information and the like is sent out.

Above-mentioned technical scheme can judge whether the transport of a cigarette 10 appears blockking up in transfer passage 1 to when a cigarette 10 appears blockking up, in time shut down the upstream equipment, in order to avoid causing further loss.

In some embodiments, the cushioning component 4 comprises a spring. One end of the spring is fixedly arranged, and the other end of the spring extends out of the end part of the detection part 3. The arrangement is such that when the deflector 2 deforms, it first touches the buffer member 4 and then touches the detection member 3. Alternatively, the entire buffer member 4 is located outside the detection member 3, and the buffer member 4 and the detection member 3 are not in a fitted relationship. But the position of the cushioning part 4 is also sufficient to be able to perform the cushioning function.

Referring to fig. 3, in some embodiments, the buffering member 4 is sleeved outside the detecting member 3.

Referring to fig. 3, in some embodiments, the baffle 2 is configured to be arcuate. The arc structure enables the cigarettes 10 to be in smooth transition, and the probability of blockage of the cigarettes 10 is reduced.

Referring to fig. 1 to 4, a specific implementation of the detection member 3 is described below.

In some embodiments, the detection component 3 comprises a microswitch 31 and a relay (not shown). The microswitch 31 is arranged outside the air guide 2. The relay is electrically connected with the microswitch 31 and used for triggering the coil of the relay to be electrified when the microswitch 31 detects the flow guide piece 2; and the normally open contact of the relay is electrically connected with the PLC of the equipment and used for sending a shutdown signal to the PLC of the equipment when the coil is electrified.

Referring to fig. 1 to 4, the microswitch 31 is fixedly mounted on the rack through the connecting part 5, the probe of the microswitch 31 is located between the connecting part 5 and the flow guide 2, and the buffer part 4 is sleeved outside the probe of the microswitch 31.

Referring to fig. 1 to 4, the connection member 5 includes a connection plate. The connecting plate is for example a steel plate. The steel plate is welded and fixed to a frame (not shown). The detection component 3 is fixedly connected with the frame through a nut. After the detection member 3 is mounted in place, the position is determined and not moved.

Referring to fig. 1-4, specific embodiments are described below.

Take a certain type of cigarette storage and transportation system as an example. As shown in figure 1, the cigarette conveying system mainly comprises a tray loader, a tray unloader and a conveying channel 1 to finish the conveying of cigarettes 10. The cigarettes 10 are conveyed as shown in fig. 1, and the cigarettes 10 are conveyed from the direction of a tray loader and the direction of a tray unloader, are converged and then are conveyed to a downstream machine through a conveying channel 1. The corner 13 is easy to be blocked, which causes the cigarette 10 to be damaged by extrusion and causes the flow guide element 2 to be deformed by extrusion.

The normal passage corner 13 operates as shown in fig. 2, and the flow guide 2 at the corner 13 is fixed by the first connecting piece and the second connecting piece. The other ends of the first connecting sheet and the second connecting sheet are fixed on a machine through nuts. The cigarettes 10 are vertically conveyed forwards by the belt, guided by the guide piece 2 and then transversely conveyed.

As shown in figure 3, the skewed cigarettes are easily clamped at the diversion piece 2, at the moment, the first belt conveying device 14 still vertically conveys the cigarettes 10 forwards, so that the conveying channel 1 is blocked and extruded, at the moment, the diversion piece 2 is jacked up by the cigarettes 10 due to overlarge stress, the first connecting piece and the second connecting piece are also bent upwards, and the cigarettes 10 in the channel are also extruded and deformed due to stress.

The detection part 3 is automatically stopped when the conveying channel 1 is extruded, and can also be connected with an alarm device to realize stop alarm, so that the increase of the stop time and the increase of the rejection rate caused by the blockage of the cigarettes 10 are prevented.

Referring to fig. 1, a microswitch 31 is mounted above the flow guide 2 at the corner 13 of the channel above the conveyor channel 1. When the conveying channel 1 is blocked to extrude the cigarettes 10, the flow guide piece 2 is extruded by the cigarettes 10 to lift the micro switch 31 to sense the flow guide piece 2 greatly, and at the moment, the micro switch 31 outputs a 24V direct-current voltage signal. When there is no jam or jam, the microswitch 31 is not sensed, and no signal is output.

The micro switch 31 is used for controlling the power-on and power-off of the coil of the relay, and a normally open contact of the relay is connected with a normally open contact of a stop button of the equipment main machine in parallel. When the cigarette 10 extrudes the diversion piece 2 and is induced by the microswitch 31, the signal end outputs a 24V direct-current voltage signal, the relay coil is electrified, the normally open contact of the relay coil is closed, the closing of the contact enables the PLC of the equipment to receive a stop signal, the equipment stops running, and the loss of raw materials is avoided.

The signal line of the microswitch 31 is connected to one end of the coil of the relay, the other end of the coil of the relay is connected to the common end of the direct current power supply, and the voltage of the common end is direct current of 0V. The one end of the normally open contact of relay is connected to 24V direct current voltage, and the other end is connected to the PLC input point that the host computer shut down the button and normally open contact that normally open contact and shut down the button is parallelly connected promptly, and arbitrary one closure in two normally open contacts all can make the PLC input point receive shutdown signal.

The working principle of the circuit part is as follows: when the microswitch 31 senses the guide piece 2, the signal end outputs a 24V direct current voltage signal, the coil of the relay is electrified, the contact is closed, the PLC of the equipment receives a corresponding signal, which is equivalent to that the stop button is pressed down, so that the equipment does not run any more, the conveying channel 1 is stopped to supply cigarettes 10, and the loss of a large number of cigarettes 10 is reduced.

The technical scheme of the embodiment of the invention realizes the detection of the cigarette conveying extrusion state of the conveying channel, can reduce the waste amount and improve the stability of equipment.

The following describes a specific embodiment of the conveyor channel 1.

Referring to fig. 1-3, in some embodiments, the carryway 1 includes a first belt conveyor 14 and a second belt conveyor 16. The first belt conveyor 14 and the second belt conveyor 16 are power devices for moving the cigarettes 10 to realize conveying. The first belt conveyor 14 is a straight belt, i.e. the belt has no turns, corners 13. The belt of the second belt conveyor 16 is also a straight belt. The first belt conveyor 14 and the second belt conveyor 16 together provide power for conveying the cigarettes 10 in the first path 11.

The flow guide 2 is located at the corner junction of the first channel 11 and the second channel 12, and makes the first channel 11 and the second channel 12 smoothly transited.

Referring to fig. 1-3, in some embodiments, the baffle 2 is arcuate. The flow guide piece 2 is used as an arc-shaped flow guide sheet, so that the cigarettes 10 in the first channel 11 smoothly enter the second channel 12.

The installation mode of water conservancy diversion spare 2 does, and the both ends of connection piece all are connected with the foil, and the foil is receiving external force and is buckling deformation easily in the thin slice thickness direction to drive water conservancy diversion spare 2 and warp. It will be appreciated that other implementations may be used

Specific examples thereof are: in some embodiments, the cigarette conveying device further includes a first connecting tab (not shown) and a second connecting tab (not shown). The first end of the first connecting piece is fixedly arranged, and the second end of the first connecting piece is connected with the first end of the flow guide piece 2. The first end of the second connecting piece is fixedly arranged, and the second end of the second connecting piece is connected with the second end of the flow guide piece 2. Wherein, the surface of the first connecting piece and the surface of the second connecting piece are intersected with the conveying direction of the first channel 11, and the first connecting piece and the second connecting piece can deform in the conveying direction of the first channel 11.

Both the first and the second connecting piece can be deformed in the direction a shown in fig. 1, which in turn drives the flow guide element 2 to deform relative to the conveying channel 1.

In some embodiments, the surface of the first connecting piece and the surface of the second connecting piece are both perpendicular to the conveying direction of the first channel 11. That is, both ends of the guide member 2 are deformed toward the a direction.

In order to prevent the first connecting piece and the second connecting piece from being deformed too much, a stopper member may be provided for the first connecting piece and the second connecting piece. The limiting part prevents the deformation of the first connecting sheet and the second connecting sheet from being too large, and prevents the first connecting sheet and the second connecting sheet from being damaged.

In some embodiments, the limiting parts are separately arranged for the first connecting piece and the second connecting piece respectively.

Referring to fig. 1 to 3, in some embodiments, the cigarette conveying device further comprises a first limiting member, which is mounted near the first connecting piece and is used for limiting the deformation amount of the first connecting piece.

Specifically, the first stopper part includes a first fixing plate and a second fixing plate 62. The first fixing plate is installed upstream of the first connecting piece, and serves to limit the amount of deformation of the first connecting piece toward the upstream of the first passage 11. The second fixing plate 62 is installed downstream of the first connecting piece, and serves to limit the amount of deformation of the first connecting piece toward the downstream of the first passage 11.

The first fixing plate has, for example, a bent portion whose shape conforms to a path along which the first connecting piece is deformed downward to limit the maximum amount of deformation of the first connecting piece toward the lower side in fig. 1.

The first fixing plate has, for example, a bent portion having a shape conforming to a path along which the first connecting piece is deformed upward to limit the maximum amount of deformation of the first connecting piece toward the upper side in fig. 1.

Referring to fig. 1 to 3, in some embodiments, the cigarette conveying device further comprises a second limiting member, which is mounted near the second connecting sheet and is used for limiting the deformation amount of the second connecting sheet.

The second limiting part has various realization modes, and the maximum deformation of the second connecting piece can be limited.

In some embodiments, the second limiting member comprises a third fixing plate and a fourth fixing plate. The third fixing plate is mounted upstream of the second connecting piece and serves to limit the amount of deformation of the second connecting piece towards the upstream of the first channel 11. The fourth fixing plate is mounted downstream of the second connecting piece and serves to limit the amount of deformation of the second connecting piece towards the downstream of the first channel 11.

The third fixing plate has, for example, a bent portion, and the shape of the bent portion conforms to the path along which the second connecting piece is deformed downward, so as to limit the maximum amount of deformation of the second connecting piece toward the lower side in fig. 1.

The fourth fixing plate has, for example, a bent portion having a shape conforming to a path along which the second connecting piece is deformed upward to limit the maximum amount of deformation of the second connecting piece upward as viewed in fig. 1.

The cigarette conveyor's that above-mentioned technical scheme provided work flow as follows: as shown in fig. 1, cigarettes 10 in the warehouse are conveyed by the discharging unit conveyor belt, buffered by the movable arc-shaped flow guide piece 2 at the corner and then conveyed downwards; then the cigarette is converged with the cigarettes conveyed by the tray unloading machine and sent to a packing machine. The detection part 3 detects the material level of the discharging unit, when the discharging unit replenishes smoke, the detection part 3 is not shielded, the conveyor belt runs continuously, and when the detection part 3 is shielded, the conveyor belt is stopped temporarily to prevent the blockage caused by the over-full material level at the corner 13. The detection component 3 is used for detecting the blockage of the material warehouse discharging unit, when the discharging unit replenishes smoke, the material level at the corner of the material level is over full, the arc-shaped flow guide piece 2 is jacked up to enable the detection component 3 to sense the arc-shaped flow guide piece 2, the blockage alarm occurs, and the material warehouse discharging unit stops. The level detection is realized by the level detecting part 6.

As shown in fig. 2, the detecting member 3 is fastened to a steel plate of the frame by a nut 32 and is rigidly connected to the steel plate. The detection head of the detection component 3 judges whether the blockage occurs or not by detecting the position of the movable arc-shaped flow guide part 2. During normal operation, the cigarette 10 is conveyed to the arc-shaped flow guide piece 2 by the conveying belt and is conveyed downwards under the action of gravity and the downward elastic force of the arc-shaped flow guide piece 2. The cigarette flow is not uniform in the feeding process of the discharging unit, and the movable arc-shaped flow guide piece 2 continuously swings up and down along with the change of the cigarette flow. The arc-shaped flow guide piece 2 can also swing upwards for a certain distance due to the inertia effect when the cigarette stops. When the cigarette change rate is too large, the arc-shaped flow guide piece 2 has too large swing inertia and is easy to cause false detection. In addition, when the discharging unit is blocked, the movable arc-shaped flow guide piece 2 at the corner easily collides with the detection part 3 when jacking thrust is too large, so that the detection part 3 is damaged.

Buffering part 4 then can effectively reduce, avoid the emergence of above-mentioned condition even to realize that material storehouse mends the stable detection of cigarette in-process detecting element 3 to curved water conservancy diversion spare 2, avoid detecting element 3 to receive the striking and damage.

The buffer part 4 can play a role in stabilizing and buffering the movable arc-shaped flow guide part 2. The buffer member 4 is fixedly connected to the detecting member 3, and the buffer member 4 provides a buffering force to the deflector 2. When the diversion part 2 extrudes the spring upwards, the spring can apply an elastic force reversely, so that the arc diversion part 2 can swing stably under the spring buffering force when the smoke amount at the corner 13 changes. When serious jam occurs, the arc-shaped diversion part 2 can be extruded towards the detection part 3, and the elasticity applied to the diversion part 2 by the buffer part 4 is larger, so that the arc-shaped diversion part 2 can be prevented from impacting the detection part 3 to play a role in protecting the detection part.

On the disk unloader, as shown in fig. 3, a buffer member 4 is mounted on a detection portion of the detection member 3 at a corner of the discharge unit, the buffer member 4 being a spring in particular. The diameter of the detection head of the spring diameter detection component is 1cm, and the spring and the detection head are concentrically arranged so as to be sleeved on the detection component 3 and not to be detected. One end of a spring which penetrates through the detection head is welded on a fastening nut of the detection part 3, which is positioned on the lower side of the steel plate, so that the buffer device 4 is convenient to disassemble and assemble when the detection part 3 is replaced. The other end of the spring is suspended by about 2cm more than the detection head part according to the detection requirement, namely X is about 2 cm.

When the cigarette 10 is too much and is seriously blocked, the arc-shaped flow guide part 2 is jacked up as shown in figure 4, and the spring is extruded by the arc-shaped flow guide part 2 to generate a deformation distance x. If the spring rate coefficient is k, the spring force F generated by the spring according to the hooke's theorem is kx, and the spring deformation distance is proportional to the force applied to the arc-shaped air guide member 2 by the spring with a larger spring. When the arc-shaped flow guide piece 2 is closer to the detection part, the larger the deformation distance of the spring is, the larger the corresponding elastic force is, and the effective buffer protection effect can be achieved when the cigarette 10 is extruded and blocked.

The technical scheme provided by the embodiment of the invention has high practicability, and the buffer component is fixed on the steel plate nut to facilitate disassembly and assembly. The detection part realizes reliable detection of the arc-shaped flow guide part 2, reduces damage to the detection head caused by overlarge impact of the arc-shaped flow guide part 2, and reduces the failure rate.

The embodiment of the invention also provides a cigarette storage and conveying system which comprises a tray loader, a tray unloader and a cigarette conveying device in any technical scheme of the embodiment of the invention. Both the tray loader and the tray unloader are used for throwing cigarettes 10 into the conveying channel 1 of the cigarette conveying device.
