Description

Technical Field

[0001] The invention belongs to the technical field of material distribution in a tobacco industry wrapping workshop, and relates to a power-regulated gravity-type material station. Background Art

[0002] Material distribution in tobacco industry packaging workshops typically involves placing pallets of various auxiliary materials, or pallets of a single auxiliary material, within the production line. Operators, based on the unit's material consumption, remove the materials from the pallets and place them at designated locations on the production equipment. Once a pallet of auxiliary materials is consumed, the operator first calls for the empty pallet to be recovered. Once the empty pallet is recovered, the auxiliary material distribution call can be made. This often leads to the following technical issues: 1. A significant amount of labor is required to palletize the various auxiliary materials before handling; 2. The operator is required to call for material distribution; and 3. The operator is required to manage material consumption. Consequently, the entire material distribution process consumes significant manpower and resources, resulting in low efficiency. Summary of the Invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a non-powered gravity material station, which is used in cigarette making units and can be used in conjunction with intelligent manipulators to realize automatic material discharge, meet manual material collection, ensure orderly material distribution, and improve work efficiency.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the present invention is: a non-powered gravity-type material station, characterized in that it includes a roll paper conveying device, a turbine screw lifting device, a base and a controller. The roll paper conveying device is tilted and consists of a concave conveying bracket and a plurality of anti-slip components, and the plurality of anti-slip components are rotatably mounted on both sides of the concave conveying bracket. The multiple roll papers located in the concave conveying bracket slide down to the bottom material removal port under the action of gravity. The anti-slip components can prevent the roll papers from sliding down too fast and separate adjacent roll papers to facilitate manual material removal. One end of the bottom of the concave conveying bracket is rotatably mounted on the base, and the other end of its bottom is overlapped with the turbine screw lifting device, and the turbine screw lifting device is fixed to the base. The turbine screw lifting device is used to adjust the inclination of the concave conveying bracket according to the different weights of the roll papers, thereby ensuring that the roll papers can slide smoothly. On one side of the concave conveyor bracket are located a first, second, and third photoelectric switch, all connected to the controller. The first and third photoelectric switches are located at the discharge and take-out ports, respectively, while the second photoelectric switch is located between the first and third photoelectric switches. These three photoelectric switches detect the presence of spliced ​​paper at their respective locations and transmit the detection signal to the controller, enabling automated unloading control.

[0005] Preferably, each anti-slip component comprises a ratchet shaft and a plurality of baffles, the ratchet shaft being mounted perpendicular to the concave conveyor bracket, and the plurality of baffles being fixed to the outer wall of the ratchet shaft. As the webs slide downward, the ratchet shaft and the baffles thereon rotate, extending between adjacent webs to separate them.

[0006] Preferably, the anti-slip component is divided into a first anti-slip component and a second anti-slip component. The multiple baffles on the first anti-slip component are evenly arranged along the middle of the corresponding ratchet shaft, and the multiple baffles on the second anti-slip component are evenly arranged along the two ends of the corresponding ratchet shaft. The first anti-slip component and the second anti-slip component are alternately arranged along the concave conveying bracket to avoid mutual interference between the baffles on adjacent ratchet shafts during rotation.

[0007] Preferably, the first anti-slip component is provided with three blocking pieces in total, and the second anti-slip component is provided with six blocking pieces in total, so as to ensure that the blocking pieces extend between two adjacent splicing papers.

[0008] Preferably, the blocking piece is a square sheet structure, which is welded to the ratchet shaft for ease of processing and manufacturing.

[0009] Preferably, a roller is mounted on the crossbeam at the top of the worm screw lifting device, and the roller contacts the bottom of the concave conveyor bracket. The crossbeam increases the support area of ​​the concave conveyor bracket. When adjusting the tilt angle of the web-wound conveyor device, the rotation of the roller reduces friction between the concave conveyor bracket and the crossbeam, thereby reducing wear.

[0010] Preferably, the ends of the crossbeam are clamped in two slide rails, which are respectively fixed to two upright posts, and both upright posts are fixed to the base. The upright posts support the slide rails, and the slide rails guide the up and down movement of the crossbeam, ensuring more stable angle adjustment of the web-spinning conveyor.

[0011] Preferably, a plurality of casters are installed at the bottom of the base, and a locking device is installed beside each caster. The casters facilitate moving the material station to the target location, and the locking device is used to fix the material station to ensure stability during the material transportation process.

[0012] Preferably, the locking device consists of a nut and a screw. The nut is welded to the bottom of the base and screwed to the screw. The bottom of the screw is welded to a support base. The nut and screw structure facilitates manual adjustment, and the support base can enhance the load-bearing area and stability of the material station when it is fixed.

[0013] The non-powered gravity-based material handling station provided by this invention can be used in conjunction with an intelligent manipulator, enhancing automation and intelligent production. The inclined roll-to-roll conveyor allows the rolls to slide under gravity and be transported to the reel opening, reducing energy consumption. A baffle in the anti-slip component separates adjacent rolls, facilitating manual retrieving. Furthermore, three photoelectric switches and a controller are used to control roll-to-roll feeding, ensuring smooth conveying. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following, in conjunction with the accompanying drawings of the embodiments of the present invention, clearly and completely describes the technical solutions of the embodiments of the non-powered gravity-type material station provided by the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present invention.

[0039] like Figure 1 As shown, the present invention provides a non-powered gravity material station, which includes a roll-to-roll paper conveying device 1, a turbine screw lifting device 2, a base 3 and a controller.

[0040] The roll-to-roll paper conveyor 1 is tilted and consists of a concave conveyor bracket 11 and multiple anti-slip components 12. The concave conveyor bracket 11 is a frame structure with a concave storage space. A baffle 13 is located at its bottom, and hollow structures are formed on both sides to accommodate the anti-slip components 12. Each anti-slip component 12 consists of a ratchet shaft 14 and multiple baffles 15. The ratchet shaft 14 is mounted perpendicular to the concave conveyor bracket 11 within the hollow structure. The baffles 15 are square plates welded to the outer wall of the ratchet shaft 14.

[0041] like Figure 3 and Figure 4 As shown, the anti-slip component 12 is divided into a first anti-slip component 121 and a second anti-slip component 122. The first anti-slip component 121 is provided with three baffles 15, which are evenly arranged along the middle of the corresponding ratchet shaft 14; the second anti-slip component 122 is provided with six baffles 15, which are evenly arranged along the two ends of the corresponding ratchet shaft 14. Figure 1As shown, the first anti-slip components 121 and the second anti-slip components 122 are alternately arranged along the concave conveyor bracket 11 to prevent the blocking pieces 15 on adjacent ratchet shafts 14 from interfering with each other during rotation. In practical applications, the blocking pieces 15 can also be configured as triangular, trapezoidal, or other sheet structures. There is no specific limitation on the shape and number of blocking pieces 15, as long as the blocking pieces 15 can extend between two adjacent webs during rotation of the anti-slip component 12.

[0042] A first photoelectric switch 16, a second photoelectric switch 17, and a third photoelectric switch 18 are located on one side of the concave conveyor bracket 1. The first and third photoelectric switches 16 and 18 are located at the discharge and take-out ports, respectively, with the second photoelectric switch 17 positioned between them. If the concave conveyor bracket 1 can accommodate ten rolls of splicing paper 4 (full capacity), the second photoelectric switch 17 is positioned at the fifth roll (counting from bottom to top). In practice, the second photoelectric switch 17 can alternatively be positioned at the fourth or sixth roll, as long as the refill requirements are met and the refill signal is provided. Each of the three photoelectric switches is connected to a controller, transmitting their detection signals to the controller for automated unloading control.

[0043] One end of the bottom of the concave conveying bracket 1 is rotatably mounted on the base 3, and can be installed in a hinged manner. The other end of its bottom is connected to the turbine screw lifting device 2. The turbine screw lifting device 2 is manually cranked, and a crossbeam 22 is provided on the top of its screw 21. The top of the crossbeam 22 is provided with a roller, and the roller contacts the bottom of the concave conveying bracket 11. The ends of the crossbeam 22 are clamped in two slide rails, and the two slide rails are respectively fixed to two columns 23. Both columns 23 are fixed to the base 3. In a preferred embodiment, the connection between the columns 23 and the base 3 is provided with reinforcing ribs 24 to increase the connection strength.

[0044] The entire worm screw lifting device 2 is fixed to the base 3 by bolts. The base 3 is a frame structure and can be welded with I-beams or square steel. A plurality of casters 31 are installed at the bottom of the base 3, and a locking device 32 is installed on the side of each caster 31. Figure 2 As shown, the locking device consists of a nut 321 and a screw 322. The nut 321 is welded to the bottom of the base 3 and threadedly connected to the screw 322. A support base 323 is welded to the bottom of the screw 322. In this embodiment, the base 3 has a square frame structure, and there are four casters 31 and four locking devices 32. In actual applications, the base 3 can also be configured as a circular or other shaped frame or plate structure. There is no specific limitation on the number of casters 31 and locking devices 32.

[0045] Move the non-powered gravity material station provided by the present invention to the target placement position of the cigarette making unit, manually twist the screw 322 in the locking device 32, and move the screw 322 downward until the support base 323 supports the ground and the caster 31 is off the ground, thereby fixing the material station.

[0046] When the entire cigarette-making machine begins operation, the concave conveyor support 11 is empty of the splicing paper 4. At this point, all three photoelectric sensors are activated, transmitting a detection signal (the initial delivery task signal) to the controller. The intelligent manipulator or intelligent delivery robot then uses its end effector to sequentially pick up fourteen splicing papers 4 and place them at the discharge port. Under the influence of gravity, the fourteen splicing papers 4 slide sequentially to the end of the concave conveyor support 11 and are stopped by the baffle 13, thus completing the initial delivery task.

[0047] As the web 4 slides down, the anti-slip member 12 rotates, and the blocking piece 15 on the ratchet shaft 14 extends into and out of the space between two adjacent webs 4. When the web is full, the two adjacent webs 4 are separated by the blocking piece 15, making it easier for humans to take the web 4 at the feeding port.

[0048] The roll paper 4 at the feeding port is manually taken away, and the remaining roll paper 4 slides to the feeding port synchronously. The first photoelectric switch 16 detects that there is no material at the discharge port, and it is in an untouched state. When there are only seven roll papers 4 left on the concave conveying bracket 11, manual material collection continues, and the second photoelectric sensor 17 detects that there is no material at the seventh roll paper, and it is in an untouched state. At this time, the controller receives that both the first photoelectric switch 16 and the second photoelectric switch 17 are in an untouched state, and sends a refill signal. The intelligent manipulator or intelligent delivery robot uses the end effector to start refilling until the second photoelectric switch 17 and the first photoelectric switch 16 are triggered at the same time, and the material is in a full state, and the refilling is completed. The program in the above controller is written by a person skilled in the art to ensure the smooth progress of the roll paper conveying process.

[0049] It should be noted that the above description is only a preferred embodiment of the present invention and does not limit the scope of implementation of the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
