Description

Technical Field

[0001] This utility model relates to the field of tobacco machinery, specifically to a conveying and unloading device for rod-shaped products. Background Technology

[0002] In the tobacco processing and manufacturing industry, when transporting cigarettes, filters, and other rod-shaped materials produced by upstream equipment to downstream equipment, the materials are typically conveyed in a multi-layered stack using conveyor systems. These materials are briefly stored before being transported to the downstream equipment, or temporarily stored in a container, which is then emptied and re-conveyed in a multi-layered stack. To reduce compression, the end plates on both sides of the container are tilted, changing the contact angle between the material-receiving head and the end plates. However, this affects the container's storage capacity. Emptying these containers is either achieved by the material-receiving head impacting the container's end plates. This impact inevitably affects the stability of the material emptying process, easily causing jams and stagnation in the container conveying, leading to channel blockages.

[0003] Patent application CN116616492A discloses a storage container for rod-shaped products and a filling, transporting, and unloading system for rod-shaped products. The storage container includes a front side plate, a rear side plate, a left end plate, a right end plate, and a bottom plate. The installation positions of the front and rear side plates are adjustable. Each of the left and right end plates includes an independent first vertical plate and a second vertical plate, which are movable back and forth. In the reset state, a narrow vertical slit is formed between the first and second vertical plates, the width of which is less than the distance between the front and rear side plates. In the active state, both the first and second vertical plates move outward so that the maximum width of the slit is equal to or greater than the distance between the front and rear side plates, thereby forming a material guiding or emptying passage. This storage container for rod-shaped products has the advantages of adaptability to various specifications, adjustable design, simple material emptying and introduction processes, and low risk of material damage. However, the disclosed structure of this storage container has the disadvantage that the first and second vertical plates are passively opened, resulting in untimely and uneven opening. Utility Model Content

[0004] In order to enable the container to open automatically and in a timely manner, and to solve the problems of container damage, channel blockage and damage to rod-shaped products caused by traditional impact opening and closing, the technical solution adopted by this utility model is: a conveying and unloading device for rod-shaped products, including a transverse conveying mechanism, an opening and closing mechanism, an opening and closing guide plate, a conveying and unloading assembly and multiple containers. The multiple containers are arranged end to end on the transverse conveying mechanism to carry rod-shaped products. A pair of L-shaped end plate assemblies are slidably arranged at both ends of the containers. The transverse conveying mechanism is located below the conveying and unloading assembly, and the opening and closing mechanism and the opening and closing guide plate are sequentially arranged on the transverse conveying mechanism along the conveying direction; The transverse conveying mechanism is used to transport the container laterally, so that the L-shaped end plate assembly of the container is opened by the opening and closing mechanism and then continuously opened by the opening and closing guide plate, so that the conveying and unloading assembly passes through the container and takes out the rod-shaped product.

[0005] Based on the above, the opening and closing mechanism includes a pneumatic opening guide plate, a mounting block, and a pair of parallel grippers. The pneumatic opening guide plate is movably connected to the pair of parallel grippers. The pneumatic opening guide plate is used to drive the pair of parallel grippers to perform opening and closing movements. The pneumatic opening guide plate is mounted on the transverse conveyor via the mounting block.

[0006] Beneficial effects: By setting up a pneumatic opening guide plate and a pair of parallel air grippers, compressed air can be used to drive the pair of parallel air grippers to open the pair of L-shaped end plate assemblies at the left and right ends of the container, so that the left and right ends of the container can be opened actively before the conveying and unloading assembly enters the container.

[0007] Based on the above, the central axis of the pair of parallel pneumatic grippers coincides with the central axis of the opening and closing guide plate.

[0008] Based on the above, the container includes a front side plate, a rear side plate, a bottom plate, and two pairs of L-shaped end plate assemblies; the front side plate and the rear side plate are both assembled and connected to the bottom plate, and the inner surfaces of the front side plate and the rear side plate are flat; the two pairs of L-shaped end plate assemblies, the front side plate, the rear side plate, and the bottom plate together form a rectangular container with an open top. The L-shaped end plate assembly includes a vertical plate. A mandrel extending in the front-to-back direction and a return spring fitted on the mandrel are installed at the bottom end of the vertical plate. A through hole is made on the bottom plate corresponding to the mandrel to allow the vertical plate to move back and forth. In the reset state, a vertical narrow slit is formed between a pair of vertical plates located on the same side of the container. The width of the narrow slit is less than the distance between the front and rear side plates. In the movable state, both pairs of vertical plates located on the same side of the container move outward so that the maximum width of the narrow slit is equal to or greater than the distance between the front and rear side plates, thereby forming a material guiding or emptying passage.

[0009] Beneficial effects: By designing the container as a rectangular container with an open top and actively openable left and right ends, it can not only hold rod-shaped products, but also easily remove rod-shaped products from the container without damage.

[0010] Based on the above, a bottom connecting plate is provided at the bottom of the upright plate, a spring seat plate for installing the reset spring is provided on the bottom connecting plate, a spindle guide seat is provided on the spring seat plate, and a spreading plate parallel to the narrow slit is provided on the lower side of the spring seat plate, so that a pair of parallel pneumatic grippers spread outwards a pair of spreading plates, thereby driving a pair of upright plates to move outwards.

[0011] Beneficial effect: This structure allows the container to automatically return to its initial state after material is removed.

[0012] Based on the above, the mounting positions of the front and rear side panels in the front-rear direction are adjustable.

[0013] Based on the above, a guide groove is provided on the lower surface of the base plate along the length direction.

[0014] Based on the above, the conveying and unloading assembly includes a material handling mechanism and a feeding mechanism used in conjunction; The feeding mechanism includes a conveyor belt and a conveyor guide plate disposed on the conveyor belt, and the working surface of the conveyor belt is flush with the horizontal working surface of the transverse conveying mechanism. The conveyor belt is used to provide power to transport the rod-shaped products located on the upper layer of the container to the inlet of the material handling mechanism during the unloading process; The material handling mechanism includes inclined inner and outer conveyors and a material handling guide plate connected to the lower end of the inner and outer conveyors. The inner and outer conveyors are arranged in parallel to form an inclined conveying channel, and a guide comb plate is provided at the end of the material handling guide plate.

[0015] Beneficial effects: By designing a structure that clamps from above and below and actively conveys, it ensures that the rod-shaped products do not become disordered or squeezed during the material handling process, and avoids the phenomenon that rod-shaped products in the container are squeezed due to sliding down in the inclined channel.

[0016] Based on the above, the transverse conveying mechanism includes a guide rail, on which an inner synchronous conveyor belt, an outer synchronous conveyor belt, and a synchronous belt limiting guide plate are arranged in parallel. The opening and closing guide plate is installed on the synchronous belt limiting guide plate, and the synchronous belt limiting guide plate is arranged in parallel with the opening and closing guide plate.

[0017] Based on the above, a sealing mechanism is also provided above the container. The sealing mechanism includes a mounting bracket and a sealing guide plate disposed on the mounting bracket. The sealing guide plate is used to smooth the rod-shaped product located on the top of the container.

[0018] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model provides a conveying and unloading device for rod-shaped products. It uses an opening and closing mechanism to open the L-shaped end plate assemblies at both ends of the container, ensuring that the L-shaped end plate assemblies are evenly stressed along the spindle direction during the opening process. This ensures the stability of the opening and closing process and avoids the problems of container damage, channel blockage, and rod-shaped product damage caused by impact vibration caused by traditional impact opening and closing.

[0019] Meanwhile, an opening and closing guide plate is also installed on the transverse conveying mechanism. This guide plate not only maintains the open state of the L-shaped end plate assemblies at both ends of the container, but also serves as a guide and limiter, ensuring the stability of the container conveying and unloading process. Furthermore, by using the feeding mechanism in conjunction with the picking mechanism, the feeding mechanism can provide power to the upper rod-shaped products of the container and transport them to the entrance of the picking mechanism, thereby preventing the rod-shaped products in the inclined conveying channel from sliding backward and causing the rod-shaped products behind to be squeezed and damaged.

[0020] Furthermore, the fully loaded containers connected end to end are continuously transported in the same way, and the material handling mechanism continuously unloads the neatly stacked rod-shaped products from the containers to the downstream equipment. The whole process is carried out in a relatively sealed environment, avoiding problems such as rod-shaped products falling, tangled rods, and wrinkled rods that occur in the traditional unloading process.

[0021] Therefore, this conveying and unloading device for rod-shaped products enables the container to open automatically and in a timely manner, improving the smoothness of unloading and avoiding damage to materials caused by untimely passive opening. Attached Figure Description

Detailed Implementation

[0029] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0030] Example 1 This embodiment provides a conveying and unloading device for rod-shaped products, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the device includes a transverse conveying mechanism 2, an opening and closing mechanism 26, an opening and closing guide plate 25, a conveying and unloading assembly 5, and multiple containers 1. The multiple containers 1 are arranged end-to-end on the transverse conveying mechanism 2 to carry rod-shaped products. A pair of L-shaped end plate assemblies 14 are slidably disposed at both ends of each container 1.

[0031] The transverse conveying mechanism 2 is located below the conveying and unloading assembly 5, and the opening and closing mechanism 26 and the opening and closing guide plate 25 are sequentially arranged on the transverse conveying mechanism 2 along the conveying direction.

[0032] The transverse conveying mechanism 2 is used to transport the container 1 laterally, so that the L-shaped end plate assembly 14 of the container 1 is opened by the opening and closing mechanism 26 and then continuously opened by the opening and closing guide plate 25, so that the conveying and unloading assembly 5 passes through the container 1 and takes out the rod-shaped product.

[0033] Specifically, such as Figure 4As shown, the opening and closing mechanism 26 includes a pneumatic opening guide plate 262, a mounting block 263, and a pair of parallel pneumatic grippers 261. The pneumatic opening guide plate 262 is movably connected to the pair of parallel pneumatic grippers 261, and the pneumatic opening guide plate 262 is used to drive the pair of parallel pneumatic grippers 261 to perform opening and closing movements. The pneumatic opening guide plate 262 is mounted on the transverse conveyor 2 via the mounting block 263. The central axis of the pair of parallel pneumatic grippers 261 coincides with the central axis of the opening and closing guide plate 25.

[0034] like Figure 3 As shown, the container 1 includes a front side plate 11, a rear side plate, a bottom plate 13, and two pairs of L-shaped end plate assemblies 14. The front side plate 11 and the rear side plate are both assembled and connected to the bottom plate 13, and the inner surfaces of the front side plate 11 and the rear side plate are flat. The two pairs of L-shaped end plate assemblies 14, the front side plate 11, the rear side plate, and the bottom plate 13 together form a rectangular container with an open top.

[0035] The L-shaped end plate assembly 14 includes a vertical plate 145. A spindle 15 extending in the front-back direction and a return spring fitted on the spindle 15 are installed at the bottom end of the vertical plate 145. A through hole is made on the base plate 13 corresponding to the spindle 15 so that the vertical plate 145 can move back and forth.

[0036] In the reset state, a vertical narrow slit is formed between a pair of upright plates 145 located on the same side of container 1, the width of which is less than the distance between the front side plate 11 and the rear side plate. In the active state, both pairs of upright plates 145 located on the same side of container move outward, such that the maximum width of the narrow slit is equal to or greater than the distance between the front side plate and the rear side plate, thereby forming a material guiding or emptying passage.

[0037] Example 2 This embodiment provides a conveying and unloading device for rod-shaped products. The main difference from Embodiment 1 is that, in this embodiment: a bottom connecting plate 144 is provided at the bottom of the upright plate 145, and a spring seat plate 143 for mounting the return spring is provided on the bottom connecting plate 144. A spindle guide seat 142 is provided on the spring seat plate 143, and a spreading plate 141 parallel to the narrow slit is provided on the lower side of the spring seat plate 143, so that a pair of parallel pneumatic grippers 261 spread outwards the pair of spreading plates 141, thereby driving a pair of upright plates 145 to move outwards.

[0038] Example 3 This embodiment provides a conveying and unloading device for rod-shaped products. The main difference from Embodiment 1 is that, in this embodiment, the installation positions of the front side plate 11 and the rear side plate in the front-rear direction are adjustable. A guide groove 17 is provided on the lower surface of the base plate 13 along its length.

[0039] Example 4 This embodiment provides a conveying and unloading device for rod-shaped products. The main difference from Embodiment 1 is that in this embodiment, the conveying and unloading assembly 5 includes a material handling mechanism 51 and a feeding mechanism 4 used in conjunction. The feeding mechanism 4 includes a conveyor belt 41 and a conveying guide plate 42 disposed on the conveyor belt 41. The working surface of the conveyor belt 41 is flush with the horizontal working surface of the transverse conveying mechanism 2.

[0040] The conveyor belt 41 provides power to transport the rod-shaped products located on the upper layer of container 1 to the inlet of the material handling mechanism 51 during the unloading process. The material handling mechanism 51 includes inclined inner and outer conveyors 52 and a material handling guide plate 512 connected to the lower end of the inner and outer conveyors 52. The inner and outer conveyors 52 are arranged in parallel to form an inclined conveying channel 511. The end of the material handling guide plate 512 is provided with a guide comb plate.

[0041] Example 5 This embodiment provides a conveying and unloading device for rod-shaped products. The main difference from Embodiment 1 is that in this embodiment, the transverse conveying mechanism 2 includes a guide rail 24, on which an inner synchronous conveyor belt 21, an outer synchronous conveyor belt 22, and a synchronous belt limiting guide plate 23 are arranged in parallel. The opening and closing guide plate 25 is installed on the synchronous belt limiting guide plate, and the synchronous belt limiting guide plate 23 is arranged parallel to the opening and closing guide plate 25.

[0042] Example 6 This embodiment provides a conveying and unloading device for rod-shaped products. The main difference from Embodiment 1 is that, in this embodiment, a sealing mechanism 3 is also provided above the container 1. The sealing mechanism 3 includes a mounting bracket 31 and a sealing guide plate 32 disposed on the mounting bracket 31. The sealing guide plate 32 is used to smooth the rod-shaped products located at the top of the container 1.

[0043] Specifically, the conveying and unloading device for rod-shaped products provided by this utility model operates as follows: Fully loaded containers connected end to end are horizontally conveyed to the material handling mechanism 51 under the action of the transverse conveying mechanism 2. The guide comb plate of the material handling guide plate 512 enters the guide groove 16 symmetrically distributed on the upper surface of the bottom plate. At the same time, the parallel pneumatic gripper 261 works to drive the pneumatically opening guide plate 262 to open the left end plate of the container end plate 12. At this time, the gap between the two L-shaped end plate assemblies 14 of the left end plate is the same as the distance between the front and rear side plates 11 of the container. The material handling mechanism 51 enters the inner cavity of the container 1.

[0044] As container 1 is further conveyed, under the action of the opening and closing guide plate 25, the left end plate of the container remains open, and the rod-shaped products inside the container are lifted into the inclined conveying channel 511. Under the action of the inner and outer conveyors 52 and the feeding mechanism 4, the rod-shaped products inside container 1 are emptied.

[0045] When the material handling mechanism 51 reaches the critical position between two adjacent containers 1, the parallel pneumatic gripper 261 simultaneously opens the right end plate of the current container and the left end plate of the next container, connecting the two containers. The material handling mechanism 51 then exits the current container and smoothly enters the next container, ensuring continuous and uninterrupted emptying and output of the rod-shaped products.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
