Description

Technical Field

[0001] The utility model relates to the technical field of alkali product packaging, in particular to an intelligent bag-feeding sheet alkali packaging machine. Background Art

[0002] The caustic soda flakes in caustic soda products are initially made of low-concentration caustic soda, which is evaporated and concentrated by the system to form a high-concentration molten caustic soda, and then solidified into flaky products by flake forming equipment. The formed caustic soda flake products need to be packaged in packaging bags for easy transportation and sale.

[0003] The intelligent bag-feeding caustic soda flake packaging machine is a type of automated intelligent mechanical equipment specially used for packaging caustic soda products. It is used for intelligent bag-feeding and packaging of formed caustic soda products. The current intelligent bag-feeding caustic soda flake packaging machine generally includes a set of matching bag-making units, a set of bag-feeding units and a set of packaging units, among which:

[0004] The bag making unit is used to cut the continuous film bag in a roll and seal one end of the cut bag body, so as to make the continuous film bag in a roll into a plurality of independent packaging bags with only one end open; the prepared packaging bags are output via a conveyor belt;

[0005] The bag delivery unit is equipped with a bag delivery robot, which is mainly responsible for orderly delivering the independent packaging bags made by the bag making unit to the packaging unit for the convenience of packaging of alkali products;

[0006] The packaging unit is mainly used to pack the formed solid alkali products into packaging bags in sequence through the feeding port, so as to package the alkali products.

[0007] However, the bag-making units, bag-feeding robots and feeding ports in the existing system are all set up one by one and work in matching order. This single-group production line is difficult to meet the actual production demand. In order to adapt to higher production capacity and improve the packaging efficiency of alkali products, the intelligent bag-feeding sheet alkali packaging machine is now designed with multiple feeding ports. Taking two feeding ports as an example, this design of multiple feeding ports can realize the packaging of multiple groups of alkali products simultaneously, thereby effectively improving the packaging efficiency. At the same time, to match the multiple feeding ports, the system is equipped with multiple groups of bag-feeding robots. Each group of robots realizes one-to-one precise docking of the feeding ports of the robots through precise servo drives and intelligent control algorithms, ensuring the fast and accurate placement of packaging bags. Therefore, this design of multiple groups of simultaneous packaging can effectively improve work efficiency and greatly increase production capacity.

[0008] However, the current set of bag-making units is difficult to adapt to the synchronous bag grabbing and bag delivery work of multiple sets of robots. To solve this problem, if the bag-making units are designed to be matched with multiple sets of robots in the same number and one-to-one correspondence, the manufacturing cost and configuration cost of the equipment system will be greatly increased due to the complex structure and large size of the bag-making units.

[0009] Therefore, how to improve the packaging efficiency of the equipment by matching a single bag-making unit with multiple sets of robots becomes a key issue. Utility Model Content

[0010] The utility model aims to provide an intelligent bag-feeding caustic soda flake packaging machine to achieve matching work between a single bag-making unit and multiple groups of manipulators, thereby improving the packaging efficiency of the equipment.

[0011] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an intelligent bag-feeding caustic soda flake packaging machine, including a packaging bag transfer device, the packaging bag transfer device includes a mobile transmission mechanism and at least two bag warehouses for storing and transferring packaging bags; the mobile transmission mechanism is used to drive the bag warehouse to move back and forth, the mobile transmission mechanism includes a transmission member and a moving member, the transmission member is used to transmit the power source and drive the moving member to move back and forth, and the bag warehouse is fixedly connected to the moving member.

[0012] The principle of this scheme is: the packaging bag transfer device of this scheme is set between the bag making unit and the bag feeding unit in actual application, and the number of bag warehouses is the same as the number of manipulators and feeding ports and they work in a one-to-one matching manner. The packaging bags transmitted from the bag making unit are temporarily stored by the packaging bag transfer device, and transferred to the manipulator for the manipulator to grab and feed the bags. At the same time, the bag warehouse is moved and replaced by the mobile transmission mechanism, so that the packaging bags made by the bag making unit can fall into different bag warehouses and be grabbed by different manipulators. Therefore, even if there is only one set of bag making units, it is possible to supply bags to multiple sets of manipulators, so that multiple sets of manipulators can simultaneously feed bags to the packaging unit, and further realize that multiple sets of feeding ports can simultaneously carry out unloading and packaging. In this way, the matching work of a single bag making unit and multiple sets of manipulators is effectively realized, so that the bag making and the grabbing actions of the manipulators are adapted to each other, and the packaging efficiency of the equipment for alkali products is improved.

[0013] At the same time, in the existing equipment structure, if multiple groups of manipulators are to grab bags from the same bag-making unit, the bag-making unit cannot be located directly behind the multiple groups of manipulators at the same time. However, since the current movements of the manipulators are to move forward and backward in a straight line in a vertical plane to grab and deliver bags, in order to make the manipulator adapt to the change in the position of the bag-making unit, it is necessary to change the movement direction and deflection angle of the manipulator, then the corresponding manipulator structure and its control algorithm need to be redesigned and adjusted, and the structure of the manipulator is precise. This improved design will undoubtedly bring about the problem of greatly increasing the design, manufacturing and maintenance costs. In the present application scheme, by setting a packaging bag transfer device between the bag-making unit and the bag-delivering unit, and using a movable bag warehouse to achieve the change in the orientation of the packaging bag, the position of the packaging bag is adapted to the movement of the manipulator. Compared with the method of improving and optimizing the manipulator, the structure is simpler, and the design, manufacturing and maintenance costs are lower.

[0014] The advantages of this solution are:

[0015] 1. Introduction of packaging bag transfer device: A packaging bag transfer device is added between the bag making unit and the bag feeding robot to temporarily store the packaging bags output by the bag making unit, and distribute the packaging bags to different robots through the movement of the moving parts in this packaging bag transfer device, so that even if there is only one bag making unit, it can efficiently support the bag supply needs of multiple groups of robots.

[0016] 2. Dynamic bag supply mechanism: The packaging bag transfer device realizes the movement of the bag warehouse through the mobile conveying mechanism, ensuring that the packaging bags produced by the bag making unit can be distributed to the corresponding robots, so that multiple groups of robots can simultaneously deliver bags to packaging units with multiple feeding ports, thereby improving packaging efficiency.

[0017] 3. Avoid the complexity of the robot structure: By setting up the packaging bag transfer device, the need to directly improve the robot structure and control algorithm to adapt to the position change of the bag making unit is avoided, the cost and complexity of the robot modification are reduced, and the simplicity and economy of the equipment system are maintained.

[0018] 4. Optimize the balance between cost and efficiency: This solution increases the flexibility and work efficiency of the system at a lower cost through the design of the packaging bag transfer device. Compared with the solution of directly adjusting the robot design or setting up multiple groups of bag-making units, this method is more economical in design, manufacturing and maintenance costs, while ensuring the consistency and efficiency of the packaging process. At the same time, the existing one-to-one matching working method of bag-making units, robots and feeding ports limits the work efficiency of the bag-making units, making it difficult to reflect and exert the high work efficiency characteristics of the bag-making units. However, through this solution, even one group of bag-making units can be matched with multiple robots and feeding ports for packaging at the same time. In this way, the work efficiency of the bag-making units is fully explored and utilized, so that the work efficiency of the bag-making units can be greatly improved.

[0019] Preferably, as an improvement, a support beam for supporting the moving member is provided partially below the moving member, the support beam is extended along the moving direction of the moving member, and the bag storage is located above the support beam.

[0020] Through the above scheme, the support beam can horizontally support the moving part, so that the moving direction of the moving part always remains in the horizontal direction, thereby indirectly supporting the bag warehouse stably through the moving part, so that the bag warehouse will not tilt and cause the packaging bags to slide during the process of storing and transporting packaging bags.

[0021] Preferably, as an improvement, a fixed beam is fixedly connected to the support beam, and the support beam and the fixed beam are vertically arranged; the mobile conveying mechanism also includes a frame, and the fixed beam is fixedly connected to the frame.

[0022] Through the above solution, the fixed beam is used to support the supporting beam and provide stable installation of the supporting beam, so that the bag warehouse is more stable when moving.

[0023] Preferably, as an improvement, the transmission member and the moving member are provided with two groups arranged in parallel, and the two groups of moving members are respectively connected and fixed to the front end and the rear end of the bag storage.

[0024] Through the above scheme, two groups of moving parts respectively move and transport the front end and the rear end of the bag warehouse synchronously, thereby making the control of the bag warehouse more flexible and avoiding the situation where a single moving part cannot achieve smooth movement and transportation of the bag warehouse when the bag warehouse is heavy.

[0025] Preferably, as an improvement, the bag storage and the moving member are fixedly connected via a connecting member, and the connecting member is a corner plate or a T-shaped plate.

[0026] Through the above scheme, the connecting piece is used to connect the bag storage and the moving piece. Through the connection of the angle plate or T-shaped plate, space can be provided for the connection and installation of the bag storage and the moving piece, thereby ensuring a stable connection relationship between the bag storage and the moving piece.

[0027] Preferably, as an improvement, the transmission member is a sprocket, the movable member is a chain meshing with the sprocket for transmission, one end of the connecting member fixes two adjacent chain plates on the chain, and the other end is fixed to the bag storage.

[0028] Through the above scheme, the meshing transmission of the sprocket and the chain can realize the mobile drive of the bag warehouse. The mobile transmission mechanism of this structure is relatively simple and has lower cost. At the same time, by fixing the adjacent chain plates through the connecting piece, the adjacent two chain links that were originally relatively movable can be relatively fixed, so that the flexible chain can be partially rigid, making the connection between the chain and the bag warehouse more stable, which is more conducive to the mobile transmission of the bag warehouse.

[0029] Preferably, as an improvement, an adjustment mechanism is provided on the frame for longitudinal sliding, the adjustment mechanism comprises a sliding shaft slidably connected to the frame and an adjustment sprocket rotatably connected to the sliding shaft, and the adjustment sprocket is also engaged with the chain.

[0030] Through the above scheme, the adjustment mechanism is used to adjust the tension of the chain. By adjusting the position of the sliding shaft on the frame, the position of the adjustment sprocket can be changed, so that the adjustment sprocket can tension the chain to different degrees.

[0031] Preferably, as an improvement, a slide groove is provided on one side of the support beam facing the movable member, the slide groove extends along the length direction of the support beam, and the movable member is located in the slide groove.

[0032] Through the above solution, the slide groove can limit the moving part, thereby fixing the moving direction of the moving part, so that the bag storage can move towards the target direction to deliver the bags.

[0033] Preferably, as an improvement, a plurality of rollers are rotatably provided at the bottom of the chute, the plurality of rollers are arranged in sequence along the length direction of the chute, and the chain contacts the upper ends of the rollers.

[0034] Through the above solution, the roller can reduce the movement resistance of the slideway to the chain, thereby being more conducive to the smooth movement and transmission of the chain to the bag warehouse. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following is further described in detail through specific implementations, but the implementation of the utility model is not limited thereto. Unless otherwise specified, the technical means used in the following implementations are conventional means well known to those skilled in the art; the experimental methods used are all conventional methods; the materials, reagents, etc. used can all be obtained from commercial channels.

[0041] Example 1

[0042] Intelligent bag supply caustic soda flake packaging machine includes: Figure 1 The packaging bag transfer device shown is arranged between the bag making unit and the bag feeding unit when in use.

[0043] The packaging bag transfer device comprises a mobile conveying mechanism and at least two bag warehouses 1 for storing and transferring packaging bags. In this embodiment, there are two bag warehouses 1, namely, a first bag warehouse 1 ( Figure 1 The middle right bag storehouse) and the second bag storehouse 1 ( Figure 1 The specific implementation method is described by taking the bag store on the left side of the middle as an example. Figure 1 The two bag warehouses 1 shown are now located at the workstations where the corresponding matching manipulators grab the packaging bags. There are also two manipulators and two feeding ports that match the bag warehouses 1. The mobile conveying mechanism is used to drive the bag warehouse 1 to move back and forth, so that the bag warehouse 1 can deliver the packaging bags made by the bag making unit to the manipulators for grabbing and delivering the bags. Specifically:

[0044] The mobile transmission mechanism includes a transmission member, a moving member and a frame 13, wherein the transmission member is rotatably arranged on the frame 13, the transmission member is used to transmit a power source and drive the moving member to move back and forth, and the bag storage 1 is fixedly connected to the moving member. The transmission member in this embodiment is a sprocket 2, and the moving member is a chain 3 that is meshed with the sprocket 2 for transmission, and the sprocket 2 is rotatably arranged on the frame 13 through a rotating shaft and using a bearing. A reduction motor 4 is also fixed on the frame 13, and of course other motors that can rotate in both forward and reverse directions can also be used. The driving shaft of the reduction motor 4 is fixedly connected to a power drive sprocket, and the power drive sprocket is also connected to the sprocket 2 of the mobile transmission mechanism through a transmission chain for power transmission.

[0045] The frame 13 is fixedly connected with a fixed beam 5 by bolts and nuts. A support beam 6 for supporting the chain 3 is provided below a part of the chain 3. The support beam 6 is horizontally extended along the moving direction of the chain 3. The support beam 6 is perpendicular to the fixed beam 5 and fixedly connected by bolts and nuts. The bag warehouse 1 is located above the support beam 6. Therefore, the chain 3 can be supported by the support beam 6, so that the chain 3 has a certain rigidity, thereby indirectly achieving stable support and transfer of the trouser pockets. In addition, in this embodiment, the sprocket 2 and chain 3 of the mobile conveying mechanism are provided with two sets of parallel arrangements. The two sets of chains 3 are respectively connected and fixed to the front end and the rear end of the bag warehouse 1. In this embodiment, as shown in FIG. Figure 2 and Figure 3 As shown, the front end of the bag warehouse 1 and the chain 3, as well as the rear end and the chain 3 are fixedly connected by a connecting piece 7, and the connecting piece 7 is an angle plate or a T-shaped plate. Furthermore, the connecting piece 7 in this embodiment is a angle plate, and one end of the angle plate is welded to fix two adjacent chain plates 14 on the chain 3, and the other end is welded to the bottom of the bag warehouse 1 or fixed with bolts and nuts.

[0046] In the specific implementation of this embodiment, the conveyor belt of the bag making unit is directly opposite to the middle of the frame 13, and the first bag warehouse is initially located at Figure 1 The position of the second bag storehouse is shown, at this time, the first bag storehouse is opposite to the conveyor belt of the bag making unit, and the second bag storehouse is located on the left side of the frame 13.

[0047] When the intelligent alkali flake packaging machine for bag supply is used to package alkali products, the packaging bags made by the bag-making unit are transported to the first bag warehouse 1 through the conveyor belt. After a certain number of packaging bags are loaded into the first bag warehouse 1, the reduction motor 4 starts to work and drives the mobile transmission mechanism to work, so that the sprocket 2 drives the chain 3 to move, and the chain 3 drives the two bag warehouses 1 fixedly connected thereto to move together, and moves the second bag warehouse 1 to the conveyor belt of the bag-making unit (i.e., the middle position of the frame) for bag storage, and the bag-making unit sends bags to the second bag warehouse 1. During the above-mentioned movement of the second bag warehouse 1, the first bag warehouse 1 also moves with the chain 3 and moves to the robot arm that matches it. At this time, the robot arm that matches the first bag warehouse 1 does not take bags from the first bag warehouse 1.

[0048] After the second bag warehouse 1 is also filled with a corresponding number of packaging bags, two groups of manipulators simultaneously take bags from the first bag warehouse 1 and the second bag warehouse 1 respectively and send the packaging bags to the packaging unit for packaging of alkali products. In this way, through the matching work of one bag making unit and two groups of manipulators, the synchronous packaging of the two groups of packages is achieved, which improves the packaging efficiency of the equipment while improving the working efficiency of the bag making unit.

[0049] After the packaging bags in the two bag warehouses 1 are taken by the robot, the reduction motor 4 starts working again and drives the chain 3 to move in the reverse direction. The chain 3 drives the two bag warehouses 1 to move in the reverse direction and reset, and then enters the next bag storage and bag taking cycle.

[0050] Example 2

[0051] In this embodiment, based on the content of embodiment 1, an adjustment mechanism is further provided on the frame 13 for longitudinal sliding, and the adjustment mechanism includes a sliding shaft 10 slidably connected to the frame 13 and an adjustment sprocket 11 rotatably connected to the sliding shaft 10 through a bearing, Figure 1 As shown, the front side wall and the rear side wall of the frame 13 are provided with vertically extending strip holes 12, and both ends of the sliding shaft 10 are provided with threads. The two ends of the sliding shaft 10 pass through the strip holes 12 on the front side wall and the rear side wall of the frame 13 respectively and are locked by nuts respectively, so that the sliding shaft 10 is fastened in the strip holes 12 to fix the adjustment sprocket 11 at a certain height position. The adjustment sprocket 11 is meshed with the chain 3 of the mobile transmission mechanism.

[0052] The specific implementation process is as follows: when the tension of the chain 3 needs to be adjusted, the nut between the sliding shaft 10 and the strip hole 12 is loosened, and the sliding shaft 10 is vertically slid along the strip hole 12 to move the sliding shaft 10 to a suitable height position. At this time, the adjusting sprocket 11 follows the movement of the sliding shaft 10 to tighten or loosen the chain 3, thereby adjusting the tension of the chain 3. After adjusting to a suitable degree, the sliding shaft 10 is fixed in the strip hole 12 again by the nut, and the height position of the adjusting sprocket 11 can be fixed. In the process of the movement of the chain 3, since the adjusting sprocket 11 is rotatably connected to the sliding shaft 10 through the bearing, the adjusting sprocket 11 can follow the movement of the chain 3 and rotate on the sliding shaft 10 to adapt to the movement of the chain 3 without blocking the chain 3.

[0053] Example 3

[0054] In this embodiment, based on the content of embodiment 1 or embodiment 2, a slide groove 8 is further provided on the side of the support beam 6 facing the chain 3, that is, Figure 1 The upper end surface shown is provided with a slide groove 8, which extends along the length direction of the support beam 6. Figure 4 As shown, the chain 3 is located in the slide groove 8, and a plurality of rollers 9 are rotatably provided at the bottom of the slide groove 8. The rotational connection relationship between the rollers 9 and the slide groove 8 can be achieved by hole-shaft matching. The specific connection and installation method is well known in the art and will not be repeated here. The plurality of rollers 9 are arranged in sequence along the length direction of the slide groove 8, and the bottom of the chain 3 contacts the upper end of the roller 9.

[0055] During specific implementation, the chain 3 is limited by the side wall of the chute 8 during movement and always moves in a fixed direction, so that the bag warehouse 1 can move in the target direction to deliver the bags. At the same time, the rollers 9 in the chute 8 reduce the resistance of the chute 8 to the movement of the chain 3, which is more conducive to the smooth movement and transmission of the chain 3 to the bag warehouse 1.

[0056] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
