Description

Technical Field

[0001] This invention relates to a system and method for packaging based on rubber bands. Background Technology

[0002] Fruits such as pears, apples, and eggplants need to be bagged during their growth process, and these bags are usually placed in batches.

[0003] Large quantities of fruit bags require a large amount of manual labor to attach rubber bands, which is labor-intensive, prone to scattering, and results in misaligned and unsightly patterns. How to automate the attachment of rubber bands to fruit bags and similar structures has become an urgent technical problem to be solved.

[0004] The existing method for bundling fruit bags with rubber bands involves purchasing large quantities of rubber bands, opening them, and then individually bundling each bag. However, this method has problems: the quality of the purchased rubber bands varies, they are prone to breakage, and during long-term storage and compression, they age and stick together, making them inconvenient to open. Furthermore, purchased rubber bands cannot be used for automated bundling of sheet-like fruit bags. The applicant has creatively replaced purchased rubber bands with rubber sleeves that are directly cut from the rubber sleeves to automate the bundling process. This is a highly innovative approach compared to the traditional method of automating the bundling of fruit bags with bulk purchased rubber bands, which involves directly cutting and bundling the rubber bands from the purchased rubber sleeves.

[0005] When using rubber bands to attach fruit bags, the applicant invented a device and method for automatically attaching rubber bands directly to the fruit bags. However, in actual use, it was found that when the rubber bands were being made from the rubber band output cylinder, due to the inherent flexibility of rubber, they would stick together during compression, making them impossible to open and thus preventing the fruit bags from being properly bound. How to prevent this sticking during the rubber band production process has become an urgent technical problem to be solved. Summary of the Invention

[0006] In general, the technical problem to be solved by this invention is to provide a system and method for packaging based on rubber bands.

[0007] To solve the above problems, the technical solution adopted by the present invention is as follows: To achieve automated packaging, a rubber band-based packaging system is provided, including a packaging component; the packaging component has a packaging station. The packaging assembly includes a frame assembly, which is equipped with a rubber band fitting assembly for making the required rubber band parts and stretching the rubber band parts.

[0008] As a further improvement to the above technical solution: An input conveyor belt and an output conveyor belt are respectively installed on the entry side and the output side of the packaging station; A transfer robot arm with mechanical grippers is set up next to the packaging station; In this process, a transfer robot arm drives a mechanical gripper to hold the materials to be packaged and rotate them between the output end of the input conveyor belt, the input end of the output conveyor belt, and the packaging station.

[0009] Rubber band accessories include a feeding component; The feeding assembly includes a storage reel with a rubber sleeve wound on it, and a guide assembly is provided on the output side of the storage reel. A rubber band cutting component is provided on the output side of the guide component.

[0010] To achieve automated packaging, a rubber band-based packaging method is proposed, which includes the following steps; S1, Rubber tube feeding step; S2, rubber tubing cut into rubber band pieces; S3, receiving the elastic band and spreading it open; S4, clamp the material to be packaged and place it into the rubber band component to complete the process; S5, clamps and outputs the material to be packaged.

[0011] This invention achieves automated packaging of materials such as fruit bags. It has a high degree of automation and uses rubber tubes as raw materials to replace batches of finished rubber bands, thereby completing the functions of rubber band introduction, limiting and opening.

[0012] The improved automatic fruit bag baling machine suffers from adhesion during continuous cutting of rubber bands and conveying of rubber tubes, which prevents the opening action from being completed. This invention does not require additional processes. Utilizing existing components, only the rollers need to have forward and reverse rotation to allow the rubber tubes to be pre-exposed for application of anti-adhesion materials to their inner cavities through methods such as coating or spraying. This greatly improves the bundling qualification rate.

[0013] This invention is reasonably designed, low in cost, sturdy and durable, safe and reliable, simple to operate, time-saving and labor-saving, cost-saving, compact in structure and easy to use. The specific effects are described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0022] like Figure 1-7 As shown in this embodiment, the rubber band accessory assembly, the rubber band anti-adhesion assembly, and the system and method for packaging based on rubber bands are described. like Figure 1-3 As shown, a rubber band accessory assembly includes, most notably, a stretching component (2), which can stretch manually inserted or continuously inserted rubber bands into the desired shape. The rubber band is an example; other elastic sleeves used for bundling can also be used for bundling and packaging fruit bags or plastic bags. The stretching component (2) includes a movable second movable seat (19), which can be three in number, allowing for the bundling and packaging of materials such as plastic bags or paper tubes rolled into cylindrical shapes. A finger-opening part (20) is provided on the second movable seat (19). For example, it can be a linkage mechanism or a thin rod driven by a cylinder / electric cylinder, thereby realizing the opening and closing action. The finger-spreading section (20) includes a finger carrier (21) mounted on a second movable seat (19); the second movable seat (19) can be a conventional drive or a reverse twin screw, thereby enabling opposing forces to move closer or further away.

[0023] A swinging finger (26) is provided on the finger carrier (21); it is designed with a pointed tip so that it can better enter the falling rubber band loop, or it can be designed to be telescopic.

[0024] Above the swinging finger (26) is a support station (28); the key innovation of the invention is achieved here.

[0025] At the opening station (28), the top of the swing finger (26) is brought together or opened. When the top of the swing finger (26) is brought together, it enters the inner hole of the rubber band part (5).

[0026] Preferably, the second movable seat (19) is equipped with the first movable seat (18) which is movable; the second movable seat (19) is on the first movable seat (18); and its orientation can be one horizontal and one vertical or one vertical and one horizontal.

[0027] To facilitate automated bundling, the second moving seat (19) drives the first moving seat (18) to leave the spreading station (28) and arrive at the packing station (38). When the top of the swing finger (26) opens, the inserted rubber band (5) is opened, waiting for the material to be packed (4) to be put in. By using two stations, the concentration of processes is reduced, the structure is simplified, and efficiency is improved.

[0028] At least two second movable seats (19) are arranged opposite to each other on the first movable seat (18), so that they can be driven by reverse screws; As a preferred embodiment of the swinging finger, a swinging guide groove (24) is provided at the lower part of the swinging finger (26); the bottom of the swinging finger (26) is hinged to the finger carrier (21) through a hinge shaft (23); A finger drive unit (22) is provided on the finger platform (21), and a swing arm (25) is provided laterally on the finger drive unit (22); the swing arm (25) and the swing guide groove (24) are hinged together by a hinge shaft.

[0029] It cleverly applies a swing linkage structure to the finger, and when closed, it forms an A-shape that is smaller at the top and larger at the bottom, which makes it easier to accommodate more parts at the bottom. The slope is used to guide the falling rubber band and make it easy to adjust and position it at the limit point. Compared to a straight up and down result, it can get closer and the top is smaller.

[0030] The finger carriers (21) are two, three, four or at least five, and the present invention prefers a pair because they are matched with rectangular paper bags.

[0031] A feeding assembly is installed above the opening station (28) to achieve continuous matching output; A rubber band cutting component (3) is set below the feeding component; thus, a single rubber band is made. Compared with the traditional thinking, how to automatically bundle and pack the rubber bands that have already been made, the improvement of this invention is that it abandons the idea of ​​first making a batch of rubber bands and then improving the matching mechanical structure of the batch of rubber bands. Instead, it directly improves the rubber tube. Through the strip structure of the rubber tube, the continuous production of rubber bands is guaranteed. At the same time, automation is achieved through the production of a single rubber band. This is an innovative idea without any technical inspiration.

[0032] The feeding assembly delivers a continuous rubber tube (8) to the rubber band cutting assembly (3), thereby ensuring continuous output of the rubber tube.

[0033] The rubber band cutting assembly (3) includes a cutter (17) for cutting rubber band pieces (5) at the end of the rubber sleeve (8). The cutter can be a combination of a push rod and a blade, which cuts by squeezing with a cutter roller, all within the protection range.

[0034] A pad block (14) is provided on the opposite side of the cutter (17) to provide auxiliary support. This is preferred, but a scissor structure can also be used.

[0035] An auxiliary roller (16) is provided on the input side of the cutter (17) to achieve alignment and support.

[0036] A support (27) is provided on the swinging finger (26) to restrict the position of the rubber band and control the lateral expansion width of the rubber band, which is not available in the prior art.

[0037] Its working principle is as follows: the rubber tube (8) is fed; the rubber tube (8) is cut into rubber band pieces (5); the rubber band pieces (5) are received and stretched; the materials to be packaged (4) are put into the rubber band pieces (5) to complete the process. At the opening station (28), firstly, when the top is gathered, the swing finger (26) enters the inner cavity of the rubber band part (5) and is supported and positioned by the support part (27); then, the first moving seat (18) drives the second moving seat (19) to leave the opening station (28) and arrive at the packaging station. When the top of the swing finger (26) opens, the inserted rubber band part (5) is opened, waiting for the material to be packaged (4) to be put in; During the opening process of the tip of the swinging finger (26), firstly, the finger driving part (22) drives the swinging finger (26) to swing through the swinging horizontal arm part (25) to open the rubber band part (5) in one direction. Then, the second moving seat (19) moves back to back, so that the rubber band part (5) opens in another direction to form a rectangular inner cavity. The first moving seat (18) drives the rubber band component (5) to reciprocate between the spreading station (28) and the packaging station (38).

[0038] like Figure 1-7 As used alone or in combination, a rubber band anti-adhesion component includes an additive manipulator (31) mounted on a frame assembly (1); it has the ability to lift and enter the rubber tube port to spray materials and swing to avoid obstruction and interference with the opening action.

[0039] The additive robot (31) includes a robotic arm (32) with a degree of automation; a nozzle (34) is provided on the robotic arm (32) which can spray powder.

[0040] Preferably, the nozzle (34) sprays out an anti-sticking material; the anti-sticking material includes talcum powder, petroleum jelly, toner, grease or flour, and the corresponding material can be selected according to the material requirements. The principle is to prevent the inner wall of the rubber tube from sticking due to compression.

[0041] During the spraying operation, the nozzle part (34) is located at the spreading position (28) below the rubber band cutting assembly (3). A finger-spreading part (20) is provided below the rubber band cutting assembly (3); it is used to spread the rubber band into the desired shape.

[0042] As a limitation of the supporting application environment, the rubber band cutting assembly (3) includes a cutter (17) and an auxiliary roller (16) disposed behind the cutter (17). The rubber tube (8) is output to the cutter (17) via the auxiliary roller (16). The cutter (17) cuts the rubber tube (8) into individual rubber band pieces (5) for packaging the materials to be packaged (4).

[0043] A drive roller group (13) with forward and reverse rotation is provided on the input side of the rubber band cutting assembly (3) to drive the rubber tube (8) to move forward or backward.

[0044] A vacuum cleaner (29) is installed at the opening station (28) to absorb the solid powder that overflows due to the spray, thus avoiding air pollution. A negative pressure suction robot (30) is installed at the opening station (28) to absorb the outer wall of the end of the rubber tube (8) that is going down to the opening station (28). It can absorb the rubber tube and open it. Of course, it can also have a moving action to achieve a staggered opening.

[0045] The nozzle part (34) is equipped with a guide spray seat (33) on the robotic arm (32); it can temporarily store the material and spray it out by connecting the air pipe, or it can have other structures, such as a venturi tube structure or a fan or other similar structures to achieve spraying.

[0046] The nozzle section (34) is distributed on the guide spray seat (33), realizing multi-angle sandblasting, or single-hole spraying. Of course, multiple nozzles can be used for uniform spraying, and using a single nozzle is not easy to clog, and the air flow is large.

[0047] The anti-adhesion component is in a sprayed state; During the spraying process, the continuous rubber sleeve (8) is located at the spreading position (28). The nozzle (34) enters or approaches the port of the rubber tube (8) and sprays the coating onto the inner wall of the rubber tube (8).

[0048] After the spraying state, there is a single-piece cutting state. In the single-piece cutting state, the rubber tube (8) with the sprayed material attached to the inner wall returns to the cutting position at the cutter (17).

[0049] In step S1, an anti-sticking material is applied to the port of the rubber tube (8). First, under the forward drive of the drive roller group (13), the continuous rubber tube (8) arrives at the spreading station (28), and the nozzle part (34) enters or approaches the port of the rubber tube (8) and sprays the coating material onto the inner wall of the rubber tube (8). Then, under the reverse drive of the drive roller group (13), the continuous rubber tube (8) leaves the spreading station (28) and returns to the cutter (17) to enter the single-piece cutting state. Among them, for the rubber tube (8) located at the opening station (28), the negative pressure adsorption robot (30) adsorbs the outer wall of the end of the rubber tube (8) and opens the port; when the spraying operation is carried out, the vacuum cleaner (29) is started. like Figure 1-7 A system based on rubber band bundling includes a bundling component (36); the bundling component (36) has a bundling station (38); thereby completing the bundling of fruit bags and the like with rubber bands.

[0050] The packaging assembly (36) includes a frame assembly (1), on which a rubber band fitting assembly is provided for making the required rubber band piece (5) and for spreading the rubber band piece (5). In order to achieve automation, the present invention adopts a completely new design concept, which is not available in the prior art.

[0051] An input conveyor belt (35) and an output conveyor belt (37) are respectively installed on the entry and exit sides of the packaging station (38) to realize the connection of processes.

[0052] A transfer robot (39) is set up next to the packaging station (38). The transfer robot (39) has mechanical grippers (40), which realizes the material clamping and turnover.

[0053] In this process, the transfer is achieved by using a transfer robot (39) to drive a mechanical gripper (40) to hold the material to be packaged (4) and rotate it between the output end of the input conveyor belt (35), the input end of the output conveyor belt (37), and the packaging station (38).

[0054] To enable continuous operation, the rubber band accessories include a feeding assembly; The feeding assembly includes a storage reel (6) with a rubber tube (8) coiled on it, and a guide assembly (7) is provided on the output side of the storage reel (6); thereby achieving continuous output.

[0055] The guide component (7) is provided with a rubber band cutting component (3) on the output side.

[0056] The guide component (7) is rotated to achieve strip output; To prevent the rubber tube from wrinkling or deviating during transport, the guide assembly (7) includes an upper guide frame (9) and a lower guide frame (12) that are arranged alternately and have the same structure, thereby achieving the smoothing of the upper and lower surfaces; There is a middle contact part (10) at the front center of the upper guide frame (9) and / or the lower guide frame (12), and there are oblique guide wings (11) on both sides of the middle contact part (10). Compared with the middle contact part (10) that contacts the corresponding side surface of the rubber tube (8), the distance between the oblique guide wings (11) and the middle contact part (10) gradually increases from the middle to the edge. The middle part is pressed down by positive pressure, while avoiding the folding and deflection of the wings.

[0057] Projected onto the horizontal plane, the oblique guide wing (11) is obliquely intersecting the conveying direction of the rubber tube (8); A drive roller group (13) is provided between the storage reel (6) and the rubber band cutting assembly (3) to achieve forward and reverse driving, and / or several guide rollers (15) to achieve guiding and direction changing.

A finger-spreading part (20) is provided below the rubber band cutting component (3); The rubber band cutting assembly (3) includes a cutter (17) and an auxiliary roller (16) located behind the cutter (17). The rubber tube (8) is output to the cutter (17) via the auxiliary roller (16). The cutter (17) cuts the rubber tube (8) into individual rubber band pieces (5) for packaging the materials to be packaged (4).

[0061] The spreading action of the spreading component (2) follows the spraying action of the anti-adhesion component.

[0062] As an improvement to the method, a method for wrapping based on rubber bands is characterized by the following steps: S1, Rubber tube (8) feeding step; S2, the rubber tube (8) is cut into rubber band pieces (5); S3, receiving the rubber band component (5) and spreading the rubber band component (5); S4, clamp the material to be packaged (4) and place it into the rubber band part (5) to complete the process; S5, clamp the material to be packaged (4) and output.

In the single-piece cutting state, the rubber tube (8) with the sprayed material attached to the inner wall returns to the cutter (17).

2. A method for bundling based on rubber bands, characterized in that: Based on the system described in claim 1; method Includes the following steps; S1, Rubber tube (8) feeding step; S2, the rubber tube (8) is cut into rubber band pieces (5); S3, receiving the rubber band component (5) and spreading the rubber band component (5); S4, clamp the material to be packaged (4) and place it into the rubber band part (5) to complete the process; S5, clamp the material to be packaged (4) and output; Mechanical gripper (40) grips the material to be packaged (4) and inputs it from the input conveyor belt (35). At the packaging station (38), the material to be packaged (4) is placed into the stretched rubber band piece (5), and then the material to be packaged (4) with the rubber band piece (5) is output to the output conveyor belt (37). In step S1, with the help of the feeding assembly, firstly, the rubber tube (8) is placed on the storage reel (6) and output to the rubber band cutting assembly (3) through the guide assembly (7); under the drive of the drive roller group (13), the output rubber tube (8) is stretched by the upper guide frame (9) and the lower guide frame (12) respectively, and the direction is changed by the guide roller shaft (15); Among them, the middle contact part (10) is the middle part of the stretching rubber tube (8), and the oblique guide side wing (11) is the corresponding surface of the stretching rubber tube (8); In step S1, an anti-sticking material is applied to the port of the rubber tube (8). First, under the forward drive of the drive roller group (13), the continuous rubber tube (8) arrives at the spreading station (28), and the nozzle part (34) enters or approaches the port of the rubber tube (8) and sprays the coating material onto the inner wall of the rubber tube (8). Then, under the reverse drive of the drive roller group (13), the continuous rubber tube (8) leaves the spreading station (28) and returns to the cutter (17) to enter the single-piece cutting state. Among them, for the rubber tube (8) located at the opening station (28), the negative pressure adsorption robot (30) adsorbs the outer wall of the end of the rubber tube (8) and opens the port; when the spraying operation is carried out, the vacuum cleaner (29) is started. In step S3, at the opening station (28), firstly, when the top ends converge, the swing finger (26) enters the inner cavity of the rubber band (5) and is supported and positioned by the support (27); then, the first moving seat (18) drives the second moving seat (19) to leave the opening station (28) and arrive at the packaging station. When the top ends of the swing finger (26) open, the inserted rubber band (5) is opened, waiting for the material to be packaged (4) to be put in. During the opening process of the tip of the swinging finger (26), firstly, the finger driving part (22) drives the swinging finger (26) to swing through the swinging horizontal arm part (25) to open the rubber band part (5) in one direction. Then, the second moving seat (19) moves back to back, so that the rubber band part (5) opens in another direction to form a rectangular inner cavity. The first moving seat (18) drives the rubber band component (5) to reciprocate between the spreading station (28) and the packaging station (38).
