Description

Technical Field

[0001] The present invention relates to a multi-specification and low-damage bar-shaped material converging and diverging conveying device and method, belonging to the technical field of tobacco machinery. Background Art

[0002] During the cigarette production process, a lot of bar-shaped materials are produced, such as filter rods, cigarettes, etc. On the production line, bar-shaped material storage and conveying equipment is set between upstream and downstream equipment to match the speed difference between upstream and downstream equipment, store or release bar-shaped materials. Even when one of the upstream and downstream equipment stops, the other equipment can still continue to operate normally with the help of the bar-shaped material storage and conveying equipment, as described in the patent document 201810984683.7. There is a diversion device in the existing equipment (as Figure 2 shown). When the upstream and downstream equipment are operating normally, the bar-shaped material T1 produced by the upstream equipment is sent into the temporary storage bin A through the channel and then directly sent out through T3 and enters the downstream equipment; when a certain equipment among the upstream and downstream equipment has a problem, the bar-shaped material needs to be diverted. The diversion device of the existing technology has the following deficiencies:

[0003] 1) The existing diversion device forms a lying T-shaped channel at the converging and diverging point. When the bar-shaped material T2 in the storage barrel is discharged from the storage barrel to the left, it is necessary to prevent the temporary storage bin A from being emptied. It is necessary to lift the bar-shaped material in the temporary storage bin A to maintain the fullness of the temporary storage bin A and prevent the generation of disordered bars, which results in mutual extrusion of the bar-shaped materials. At the same time, because the temporary storage bin A and the converging and diverging port are arranged in the up and down direction with a large height difference, when the bar-shaped material T1 at the temporary storage bin A is conveyed to T3, it is damaged due to excessive mechanical pressure. Especially for cigarettes, a lot of tobacco dust will be extruded, resulting in empty ends of cigarettes, and wrinkles will appear on the outer surface of the cigarettes, thus affecting the quality of cigarettes;

[0004] 2) In the current production line layout, Figure 1 the distance L0 shown will vary due to different equipment. Because there are two specifications of the existing storage barrel 102, the transition channel 7 of the diversion device needs to be equipped with a variety of different inclination angles and different lengths to match different distances L0 and different specifications of the storage barrel 102, so there is a deficiency in poor specification adaptability;

[0005] 3) In the current production line layout, the entrance floor height of the diversion device is fixed, but different specifications of bar-shaped objects require different floor heights. The current equipment entrance floor height cannot be adjusted and cannot flexibly adapt to the production line adjustment.

[0006] In summary, the existing shunt devices cannot effectively adapt to the transportation of rod-shaped materials of various specifications, resulting in difficulties in the flexible switching of different models of rod-shaped materials on the actual production line. Otherwise, major renovations are required, which obviously involves high investment and high costs. Moreover, the traditional T-shaped channel with a side-lying layout will cause defects such as wrinkles and blanks in the rod-shaped materials at the shunt device due to excessive mechanical pressure. Therefore, it is necessary to improve the existing technology. Summary of the Invention

[0007] To reduce the mechanical pressure on the rod-shaped materials at the shunt device, avoid damages such as blanks and wrinkles in the rod-shaped materials, and at the same time, through modular design and structural innovation, flexibly adapt to rod-shaped materials of various different specifications. In this invention, on the same device of the same production line, it can be quickly adjusted according to production needs to adapt to rod-shaped materials of different specifications, and the on-site layout of the original equipment can be maintained, only by replacing the shunt device.

[0008] This invention is completed through the following technical solutions: A multi-specification and low-damage rod-shaped material shunt and confluence conveying device, which includes an input channel, a temporary storage bin, and a blanking channel that are sequentially connected on a frame. It is characterized in that the blanking channel is connected to a shunt and confluence bin, and the shunt and confluence bin is respectively connected to a transition channel and an output channel. When the rod-shaped materials produced by the upstream equipment are sent into the temporary storage bin through the input channel, and then sent into the shunt and confluence bin through the blanking channel, so that under normal production conditions, the rod-shaped materials in the shunt and confluence bin can be directly sent into the downstream packaging equipment through the output channel to complete packaging; when the downstream packaging equipment stops running, the rod-shaped materials in the shunt and confluence bin are transferred to a storage barrel through the transition channel for storage to maintain the normal production of the upstream equipment; when the upstream equipment stops running, the rod-shaped materials stored in the storage barrel are sent into the shunt and confluence bin through the transition channel, and then sent into the downstream packaging equipment through the output channel to maintain the normal production of the downstream packaging equipment.

[0009] The blanking channel is set as an L-shaped channel. The vertical end port of the L-shaped channel is the input end and is connected to the outlet of the temporary storage bin, and the horizontal end port is the output end and is connected to the inlet of the shunt and confluence bin. The horizontal end of the L-shaped channel is composed of a second upper conveying component, a second lower conveying component, and a horizontal space located between the second upper conveying component and the second lower conveying component. The vertical end of the L-shaped channel is composed of a back plate, two vertical plates spaced on the back plate, and a longitudinal space located between the two vertical plates, so that after the rod-shaped materials come out of the outlet of the temporary storage bin, they enter the L-shaped channel through the vertical end, and then the blanking and conveying of the rod-shaped materials are completed by the second upper conveying component and the second lower conveying component at the horizontal end.

[0010] The sub-converging bin is a T-shaped bin body with a cavity inside. The left side of the T-shaped bin body is provided with a feeding port, the right side is provided with a storage inlet and outlet, the bottom is provided with a discharging port, and the top is closed. Among them: the feeding port is connected to the output end of the feeding channel, the storage inlet and outlet is connected to the transition channel, and the feeding port and the storage inlet and outlet are on the same horizontal plane. The discharging port is connected to the output channel; a second adjusting member capable of adjusting the cavity volume is arranged in the cavity of the T-shaped bin body. Through the second adjusting member, the sub-converging bin is always in a full state, and the feeding port and the storage inlet and outlet are on the same horizontal plane, so that there is no height difference for the rod-shaped materials here, and thus there will be no damage caused by gravity extrusion and abrasion due to the height difference. Moreover, the rod-shaped materials leave immediately after entering the sub-converging bin, without generating pressure and without being damaged.

[0011] The second adjusting member is an elastic flexible belt, and its two ends are respectively fixed above the feeding port and the storage inlet and outlet, so that when the rod-shaped materials increase or decrease, the cavity volume of the sub-converging bin can be increased or decreased under the elastic force of the elastic flexible belt.

[0012] One end of the transition channel is connected to the back plate through a swing plate, and the other end is connected to the storage barrel inlet and outlet but not connected, forming a swing-type transition channel. Among them:

[0013] The swing plate is set as a vertical flat plate. The vertical flat plate is fixed on the rotating shaft through the shaft hole at its center. Limit blocks are arranged at the four corners of the swing plate, and waist-shaped holes are arranged on each limit block. Limit pins are arranged in the waist-shaped holes, so as to adjust the swing of the swing plate and the third upper conveying component and the third lower conveying component on it around the rotating shaft as needed, and then limit and fix through the waist-shaped holes and limit pins on the swing plate, so that the swing-type horizontal channel completes the adjustment of the inclination angle to meet the connection requirements of storage barrels of different specifications;

[0014] The transition channel is composed of a third upper conveying component and a third lower conveying component fixedly connected to the swing plate, and the space between the third upper conveying component and the third lower conveying component. Among them:

[0015] The third upper conveying component includes: an upper horizontal support plate fixed on the upper part of the swing plate, upper horizontal support rollers fixed on the upper surfaces of both ends of the upper horizontal support plate, an upper horizontal driving roller and an upper tensioning roller fixed on the upper surface of the middle part of the upper horizontal support plate, and an upper belt wound around the upper horizontal support rollers, the upper horizontal driving roller, the upper tensioning roller, and the back of the upper horizontal support plate for one week;

[0016] The third lower conveying component includes: a lower horizontal support plate fixed on the lower part of the swing plate, lower horizontal support rollers fixed on the lower surfaces of both ends of the lower horizontal support plate, a lower horizontal driving roller and a lower tensioning roller fixed on the lower surface of the middle part of the lower horizontal support plate, and a lower belt wound around the lower horizontal support rollers, the lower horizontal driving roller, the lower tensioning roller, and the upper surface of the lower horizontal support plate for one week;

[0017] Moreover, the rear ends of the upper horizontal driving roller shafts of the third upper conveying assembly and the rear ends of the lower horizontal driving roller shafts of the third lower conveying assembly both pass through the pedestal bearings on the bottom plate and are connected to the output shaft of the prime mover, so that the corresponding upper belt and lower belt can be moved under the drive of the prime mover, thereby completing the conveying of the rod-shaped materials located between the upper and lower belts.

[0018] The upper horizontal support plate and the lower horizontal support plate of the transition channel are both formed by connecting multiple plates, and the lengths of the upper belt and the lower belt respectively correspond to the lengths of the corresponding upper horizontal support plate and lower horizontal support plate, so as to adjust the length of the transition channel as needed to meet the connection requirements of different specifications of equipment.

[0019] The front and rear sides between the upper horizontal support plate and the lower horizontal support plate of the transition channel are respectively provided with a front plate and a rear plate. Among them: an adjusting screw and a nut are provided on the front side of the front plate, the adjusting screw is screwed on the corresponding bracket, and the rear side of the rear plate is connected to the swing plate through a connecting piece, so as to manipulate the rotation of the nut to drive the corresponding front and rear plates to move by the screw, realizing the width adjustment of the transition channel to meet the conveying of rod-shaped materials of different specifications.

[0020] Pads are respectively provided at the upper and lower ends of the connecting piece located at the rear side of the rear plate of the transition channel, so as to adjust the height of the transition channel through the pads to meet the connection requirements of different specifications of equipment.

[0021] The input channel is composed of a first upper conveying assembly, a first lower conveying assembly, and the space located between the first upper conveying assembly and the first lower conveying assembly, so as to complete the feeding and conveying of the rod-shaped materials through the first upper conveying assembly and the first lower conveying assembly;

[0022] The temporary storage bin includes a cavity formed by a back plate, an outer side plate and a top plate, with an inlet and an outlet provided thereon. A first adjusting member capable of regulating the cavity volume is provided in the cavity. The inlet is communicated with the input channel, and the outlet is communicated with the blanking channel.

[0023] The first adjusting member is a telescopic belt or an elastic flexible belt, among which:

[0024] One end of the telescopic belt is fixed above the output end of the input channel, and the other end bypasses at least one pulley group provided outside the blanking channel and is connected to a counterweight, so that under the combined action of the counterweight and the pulley group, the telescopic belt is always in a tensioned state, and moves into the temporary storage bin as the rod-shaped materials increase to increase the cavity volume, and moves out of the temporary storage bin as the rod-shaped materials decrease to reduce the cavity volume;

[0025] The elastic flexible belt has one end fixed above the output end of the input channel and the other end fixed outside the blanking channel, so that when the rod-shaped materials increase or decrease, the cavity volume of the temporary storage bin increases or decreases under the elastic force of the elastic flexible belt;

[0026] The first adjusting member can be used to keep the temporary storage bin B always full, effectively preventing the rod-shaped materials from being squeezed and damaged due to disorderly sticks.

[0027] The first upper conveying assembly and the first lower conveying assembly of the input channel are both conventional belt conveyors or chain conveyors, and the length, height and width of the input channel can be adjusted conventionally.

[0028] The second upper conveying assembly and the second lower conveying assembly at the horizontal end of the L-shaped channel are both conventional belt conveyors or chain conveyors, and the length, height and width of the horizontal end of the unloading channel can be adjusted conventionally.

[0029] The height, width and depth of the vertical end of the L-shaped channel can be adjusted conventionally.

[0030] The present invention has the following advantages and effects: by adopting the above technical scheme, in the process of conveying rod-shaped materials to downstream equipment or storage barrels, the T-shaped branch flow bin can be used to effectively prevent the rod-shaped materials from being squeezed and damaged due to the height difference, and the problems of wrinkling and hollow damage of the rod-shaped materials can be completely solved. At the same time, the inclination angle, length, width and height of the swinging transition channel can be adjusted to meet the connection requirements with storage barrels of different specifications, and the conveying and storage of rod-shaped materials of different specifications can be met through the adjustable channels, thereby expanding the application scope of the present invention, improving the compatibility of the equipment, adapting to the conveying of rod-shaped materials of different specifications, meeting actual production needs, saving investment and reducing costs.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. 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.

[0037] The multi-specification and low-damage rod-shaped material converging and diverging conveying device provided by the present invention includes an input channel 1, a temporary storage bin 2, and a blanking channel 3 that are sequentially connected on a back plate 4, wherein: the blanking channel 3 is connected to a converging and diverging bin 5, and the converging and diverging bin 5 is respectively connected to a transition channel 7 and an output channel 6; when the rod-shaped materials produced by the upstream device 103 are sent into the temporary storage bin 2 through the input channel 1, and then sent into the converging and diverging bin 5 through the blanking channel 3, so that under normal production conditions, the rod-shaped materials in the converging and diverging bin 5 can be directly sent into the downstream packaging device 101 through the output channel 6 to complete packaging; when the downstream packaging device 101 stops running, the rod-shaped materials in the converging and diverging bin 5 are transferred to a storage barrel 102 through the transition channel 7 for storage to maintain the normal production of the upstream device 103; when the upstream device 103 stops running, the rod-shaped materials stored in the storage barrel 102 are sent into the converging and diverging bin 5 through the transition channel 7, and then sent into the downstream packaging device 101 through the output channel 6 to maintain the normal production of the downstream packaging device 101;

[0038] The input channel 1 is composed of a first upper conveying component 11, a first lower conveying component 12, and a space 13 located between the first upper conveying component 11 and the first lower conveying component 12, and both the first upper conveying component 11 and the first lower conveying component 12 are conventional belt conveyors, and the linear speeds of the first upper conveying component 11 and the first lower conveying component 12 are kept consistent, so as to convey the rod-shaped materials entering the space 13 to the temporary storage bin 2 through the first upper conveying component 11 and the first lower conveying component 12;

[0039] The temporary storage bin 2 includes a cavity formed by a back plate 4, an outer side plate 22, and a top plate 21, as well as an inlet and an outlet communicating with the cavity. A first adjusting member 23 capable of adjusting the volume of the cavity is provided in the cavity. The inlet is communicated with the input channel 1, and the outlet is communicated with the blanking channel 3; by the first adjusting member 23, the temporary storage bin 2 is always maintained in a full state to prevent the rod-shaped materials from getting disordered;

[0040] The first adjusting member 23 is an elastic flexible belt, and the right end of the elastic flexible belt is fixed above the output end of the input channel 1, and the left end is fixed outside the blanking channel 3, so that when the rod-shaped materials increase or decrease, the volume of the cavity of the temporary storage bin can be increased or decreased under the elastic force of the elastic flexible belt;

[0041] Obviously, the first adjusting member 23 can also be set as a telescopic belt. The right end of the telescopic belt is fixed above the output end of the input channel 1, and the left end is connected to the counterweight block after bypassing at least one pulley group arranged outside the blanking channel 3. In this way, under the combined action of the counterweight block and the pulley group, the telescopic belt is always in a tensioned state, and moves into the temporary storage bin as the number of rod-shaped materials increases to increase the cavity volume, and moves out of the temporary storage bin as the number of rod-shaped materials decreases to reduce the cavity volume;

[0042] The blanking channel 3 is set as an L-shaped channel. The vertical end port of the L-shaped channel is the input end and is connected to the outlet of the temporary storage bin 2, and the horizontal end port is the output end and is connected to the transition channel 7. The horizontal end of the L-shaped channel is composed of a second upper conveying component 32, a second lower conveying component 33, and a horizontal space 34 located between the second upper conveying component 32 and the second lower conveying component 33. The vertical end of the L-shaped channel is composed of a back plate 4, two vertical plates 31 spaced on the back plate 4, and a longitudinal space located between the two vertical plates 31. Among them: the linear speeds of the second upper conveying component 32 and the second lower conveying component 33 are the same, and both are conventional belt conveyors; so that after the rod-shaped materials come out of the outlet of the temporary storage bin 2, they enter the vertical end of the L-shaped channel, and then the rod-shaped materials entering the space 34 are conveyed to the sub-confluence bin 5 by the second upper conveying component 32 and the second lower conveying component 33 at the horizontal end;

[0043] The sub-confluence bin 5 is arranged on the back plate 4 and is a T-shaped bin body with a cavity inside. The left side of the T-shaped bin body is provided with a feeding port, the right side is provided with a storage inlet and outlet, the bottom is provided with a discharge port, and the top is closed. Among them: the feeding port is connected to the output end of the blanking channel 3, the storage inlet and outlet is connected to the transition channel 7, and the feeding port and the storage inlet and outlet are on the same horizontal plane. The discharge port is connected to the output channel 6; a second adjusting member 51 capable of adjusting the cavity volume is arranged in the cavity of the T-shaped bin body. Through the second adjusting member 51, the sub-confluence bin 5 is always in a full state, effectively preventing the rod-shaped materials from being disordered; the second adjusting member 51 is an elastic flexible belt, and its two ends are respectively fixed above the feeding port and the storage inlet and outlet, so that when the rod-shaped materials increase or decrease, the cavity volume of the sub-confluence bin 5 increases or decreases under the elastic force of the elastic flexible belt;

[0044] The sub-confluence bin 5 makes the following work assignments according to the production conditions of the upstream and downstream equipment:

[0045] 1) Under normal production conditions, the rod-shaped materials in the sub-confluence bin 5 are directly sent into the downstream packaging equipment 101 through the vertical channel 6 for packaging;

[0046] 2) When the downstream packaging equipment 101 stops running, the rod-shaped materials in the sub-confluence bin 5 are transferred to the storage barrel 102 for storage through the transition channel 7 to maintain the normal production of the upstream equipment 103;

[0047] 3) When the upstream device 103 stops running, the rod-shaped materials stored in the storage bucket 102 are sent into the sub-confluence bin 5 through the transition channel 7, and then sent into the downstream packaging device 101 through the vertical channel to maintain the normal production of the downstream packaging device 101; after the rod-shaped materials enter the sub-confluence bin 5, they will leave immediately. Compared with the prior art, the height direction drop of the sub-confluence bin 5 is much smaller, and it is not necessary to support the rod-shaped materials in the silo. Therefore, the pressure of the rod-shaped materials is reduced and the damage is also reduced;

[0053] Moreover, the upper tension roller 723 of the third upper conveying component 72 and the lower tension roller 733 of the third lower conveying component 73 are both conventional tension rollers, which are used to control the tension of the corresponding upper belt 725 and lower belt 735 to meet the conveying requirements of the rod-shaped materials;

[0055] The upper horizontal support plate 722 and the lower horizontal support plate 732 of the transition channel 7 are each formed by connecting multiple plates, and the lengths of the upper belt 725 and the lower belt 735 respectively correspond to the lengths of the corresponding upper horizontal support plate 722 and lower horizontal support plate 732, so as to adjust the length of the transition channel 7 as required to meet the connection requirements with equipment of different specifications;

[0056] The front and rear sides between the upper horizontal support plate 722 and the lower horizontal support plate 732 of the transition channel 7 are respectively provided with a front plate 75 and a rear plate 76. An adjusting screw 752 and a nut 753 are provided on the front side of the front plate 75, and the adjusting screw 752 is screwed onto the corresponding support 751. The rear side of the rear plate 76 is connected to the swing plate 71 through a connecting member 761, so as to manipulate the rotation of the nut 753 to drive the corresponding front plate 75 to move, and thus the width adjustment of the transition channel 7 can be realized to meet the conveying of rod-shaped materials of different specifications;
