Description

Technical Field

[0001] The present invention belongs to the technical field of electric tool accessories, and in particular to an automatic packing device for electric tool accessories. Background Art

[0002] As a device widely used in various industries, electric tools usually need to be equipped with a series of accessories so that users can perform diverse operations according to their needs. These accessories usually include multiple bolts, nuts, and a special wrench 001 (see Figure 12 ). For the convenience of users' use and transportation, these accessories are usually put into special accessory packs.

[0003] In the traditional accessory packing process, smaller parts, such as bolts and nuts, are usually sorted and conveyed by a vibrating disk conveying system and then packed by automated equipment. The vibrating disk conveying system can improve production efficiency and reduce labor costs to a certain extent. However, for larger parts, such as special wrenches, due to their large size, they cannot be processed by the vibrating disk conveying system. Therefore, at present, these parts still need to be sorted and put into the accessory packs manually, which undoubtedly increases labor costs and production time and reduces production efficiency.

[0004] In the comparative document CN 109502093 A, the present invention application provides a packing device for electric tool accessories. The device mainly includes the following components:

[0005] Mounting base: As the basis of the entire packing device, it supports and fixes other components.

[0006] Accessory bag production department: Arranged on the mounting base, mainly including a film pulling mechanism and a sealing mechanism. The film pulling mechanism is used to draw out the bag film from the roll film, and the sealing mechanism seals the bag film to form an accessory bag.

[0007] Vibrating feeding department: Includes a feeding mechanism and a control mechanism. The feeding mechanism is arranged on the mounting base and conveys the materials into the accessory bag. The control mechanism is arranged on the feeding mechanism and is responsible for controlling the quantity of materials entering the accessory bag.

[0008] According to the description of the comparative document, the packing device can realize the automatic packing of electric tool accessory bags. However, this technical solution still has certain limitations. First, it mainly focuses on the packing process of smaller parts, and for larger parts, such as special wrenches, it has not provided an effective solution. Second, the invention does not elaborate in detail on aspects such as improving the overall packing efficiency and reducing labor costs.

[0009] Therefore, on the basis of considering the above-mentioned comparative documents, it is still necessary to research and develop a new type of electric tool accessory packing device to solve the problem of handling larger parts, improve production efficiency, reduce labor costs, and thus better meet market demands and user experiences. Summary of the Invention

[0010] In view of the above problems, the present invention provides a flexible and efficient automatic packing and integrating device for electric tool accessories. It is developed in view of the above-mentioned problems of the previous automatic packing devices for accessories, and its structural and functional features can overcome the aforementioned disadvantages of the prior art.

[0011] The object of the present invention is achieved through the following technical solutions: An automatic packing device for electric tool accessories includes a frame. In the frame, there are a finished product conveying component, a sealing mechanism, a bagging receiving hopper, and a vibrating disk installed from bottom to top. It also includes an annular conveying mechanism and a wrench conveying mechanism. The annular conveying mechanism mainly includes an annular track and a plurality of conveying frames moving along the annular track. Small parts are conveyed to the conveying frames through the vibrating disk. The wrench conveying mechanism is arranged on one side of the conveying frame and is responsible for arranging the wrenches in sequence and unloading them one by one into the conveying frame. When the conveying frame corresponds to the wrench conveying mechanism, the bottom of the conveying frame opens, and the wrenches and other parts enter the bag together from the bagging receiving hopper. After the sealing mechanism seals the bag and cuts it off, the finished accessory package is output by the finished product conveying component.

[0012] Preferably, the wrench conveying mechanism includes a wrench arranging bin, a propulsion component arranged in the wrench arranging bin, and a swinging unloading component arranged at the end of the wrench arranging bin close to the conveying frame.

[0013] Preferably, one side of the two side walls in the longitudinal direction of the wrench arranging bin is fixed to the frame. The area enclosed by the two side walls is low on both sides and high in the middle, forming an arranging area for placing and arranging wrenches. Long waist holes are symmetrically arranged along the length direction on both sides of the middle raised part in the arranging area.

[0014] Preferably, a disconnection part with a width greater than the width of the wrench is provided at one end of the arranging area of the wrench arranging bin, forming a falling opening, and the falling opening allows the wrenches to fall from the arranging area.

[0015] Preferably, an upward notch is provided on one side of the falling opening close to the center of the arranging area as a temporary docking part before the wrenches are ready to fall.

[0016] Preferably, the swinging unloading component includes a roller and an elastic pin. The roller is used to make the elastic pin act when being collided to unload the wrenches.

[0017] Preferably, the transfer frame has an openable and closable bottom plate, which is used to open downward when receiving a wrench with a weight greater than a preset weight, so that the wrench and other components fall into the transfer frame.

[0018] Preferably, the height of the bottom plate is lower than that of the wrench transfer mechanism.

[0019] Preferably, at least one collision block for hitting the roller is arranged in each transfer frame, and the collision block is located at the front end in the advancing direction of the transfer frame.

[0020] Preferably, each collision block of the transfer frame has two optional installation positions, so as to select the collision block in the correct direction for installation according to the movement direction of the transfer frame.

[0021] In summary, the present invention has the following advantages compared with the prior art:

[0022] 1. High degree of automation: The automatic packing device for electric tool accessories can realize the automatic conveying, packing and sealing of large wrenches and other small components, reduce manual operation and improve production efficiency.

[0023] 2. Compact structure: The device compactly arranges various parts such as the ring transfer mechanism and the wrench transfer mechanism, occupies a small area, and is more suitable for the production line layout of modern factories.

[0024] 3. Reduce labor intensity: The wrench transfer mechanism has no direction limit when loading and placing the wrench, and the operator does not need to specifically adjust the direction when placing the wrench, which reduces the labor intensity of the workers and is convenient and fast.

[0025] 4. Good stability: Through the precisely designed swing unloading component and the wrench arrangement bin, it is ensured that one wrench is unloaded each time.

[0026] In summary, the invention realizes the automatic packing of electric tool accessories, improves production efficiency and stability, reduces labor intensity, and has high practical value. Brief Description of the Drawings

Specific embodiments

[0040] The following further describes the present invention in combination with the embodiments shown in the drawings: With reference to all the drawings

[0041] Embodiment 1

[0042] As Figure 1-2As shown in the figure, the present invention relates to an automatic packing device for electric tool accessories, which is mainly used to automatically pack various parts. The device includes a frame 01, which serves as the basic support structure of the entire packing device. In the frame 01, a finished product conveying component 02, a sealing mechanism 03, and a bagging receiving hopper 04 are installed from bottom to top. At the same time, the present invention also includes an annular conveying mechanism 10 for sorting out each part. The annular conveying mechanism 10 mainly includes an annular track 11 and a plurality of conveying frames 12 moving along the annular track 11. In addition, the present invention also includes one or more vibrating discs 05 for inputting small parts into the conveying frame 12, and a wrench conveying mechanism 20 arranged on one side of the conveying frame 12, which is responsible for conveying the wrench to the conveying frame 12.

[0043] The present invention may also include a negative pressure adsorption component for putting the instruction manual into the conveying frame 12. The negative pressure adsorption component is a commonly used device in the prior art and is not shown in the figure. To prevent the instruction manual from getting stuck and blocked in the bagging receiving hopper 04, the present invention is provided with an anti-blocking vertical conduction component 30 inside the bagging receiving hopper 04.

[0044] Refer to Figure 4 , in the present invention, the anti-blocking vertical conduction component 30 adopts a guiding structure as the conveyor belt 31. The conveyor belt 31 is driven by an externally arranged motor 32. The conveyor belt 31 extends to the lower outlet of the bagging receiving hopper 04, so as to ensure that the instruction manual will not get stuck and blocked when entering the receiving hopper. This design effectively improves the working efficiency and stability of the automatic packing device for electric tool accessories and further optimizes the entire packing process.

[0045] As Figure 3 , 5 shown in Fig. -10, the wrench conveying mechanism 20 mainly includes the following parts:

[0046] Wrench arrangement bin 21: The overall structure of the wrench arrangement bin 21 is as Figure 10 shown in the figure. One side or the lower bottom surface of the two long side walls in the longitudinal direction is used to be fixed to the frame 01. The areas on both sides of the two side walls are low in the middle and high on both sides, forming an arrangement area 211 for placing and arranging the wrench 001. Long waist holes 212 are symmetrically arranged along the length direction on both sides of the middle raised part of the arrangement area 211, which are used to limit the movement track of the propulsion component 22.

[0047] Propulsion component 22: It is arranged in the wrench arrangement bin 21, and the pushing direction of the propulsion component 22 is towards the side of the conveying frame 12.

[0048] Swinging unloading component 23: It is arranged at the end of the wrench arrangement bin 21 close to the conveying frame 12.

[0049] The arrangement area 211 of the wrench arrangement bin 21 is provided with a break part at one end close to it, the width of which is greater than the width of the wrench 001, forming a falling opening 213. The falling opening 213 allows the wrench 001 to fall from the arrangement area 211. A notch facing upward is provided on one side of the falling opening 213 close to the center of the arrangement area 211, serving as a temporary docking part 214 before the wrench 001 is ready to fall.

[0050] The propulsion assembly 22 consists of the following:

[0051] Moving block 221: Covers the upper part of the arrangement area 211, and is provided with a groove at the lower part that matches the middle area of the arrangement area 211.

[0052] Limit rod 222: Is arranged in the groove of the moving block 221 and horizontally passes through two long waist holes 212.

[0053] Tension spring 223: One end is hooked on the limit rod 222, and the other end is fixed at a position of the wrench arrangement bin 21 close to the docking part 214.

[0054] Wrench limit part 224: Is arranged in the sliding channel at the upper part of the moving block 221 and is in sliding fit with the sliding channel.

[0055] Flap 225: Is arranged at the upper part of the docking part 214 and is used to block the wrench limit part 224.

[0056] During operation, the wrench 001 is placed in the arrangement area 211. Under the pulling force of the tension spring 223, the moving block 221 advances in the pulling force direction, pushing the whole row of wrenches 001 towards the docking part 214. The wrench limit part 224 is blocked by the flap 225 during the movement, thus realizing the positioning of the wrench 001. This design enables the wrench 001 to be smoothly conveyed in the wrench conveying mechanism 20.

[0057] The swing unloading assembly 23 mainly includes the following parts:

[0058] Swing linkage part 231: Includes a long strip-shaped plate 002 and two mounting shafts 233. The center of the plate is hinged at the center in the width direction of the wrench arrangement bin 21.

[0059] Rollers 232: Are respectively arranged on the two mounting shafts 233, and at least part of the outer peripheral surface extends beyond the end face of the wrench arrangement bin 21.

[0060] Elastic pins 234: Are respectively fixed on the two mounting shafts 233 radially facing the center of the arrangement area 211, and the length and center distance match those of the wrench 001.

[0061] Back-pushing part 235: Is slidably arranged at the front end of the falling opening 213 and is connected to the arrangement area 211 through a slide rail assembly.

[0062] Trigger 236: Installed at the hinge position of the slat 002 and interacts with the push-back member 235.

[0063] Through the coordinated action of these components, the wrench conveying mechanism 20 can arrange, convey, and drop the wrench 001, thereby transporting it into the conveying frame 12.

[0064] Working principle:

[0065] When an external object moves parallel to and against the end of the wrench arrangement bin 21, it first hits a roller 232, causing the elastic pin 234 on one side of the roller 232 to rotate inward and enter the wrench 001 more, while the other elastic pin 234 rotates outward and exits the wrench 001. At this time, one end of the wrench 001 drops under the action of gravity. When the object continues to move forward and hits another roller 232, similarly, another elastic pin 234 exits the wrench 001, causing the entire wrench 001 to fall from the dropping port 213. Thus, the unloading and placing of a single wrench 001 are completed. After the object leaves the roller 232, the wrenches 001 in the back row are pushed, and the wrench 001 originally on the docking part 214 is pushed into the dropping port 213 to fill the vacancy. At the same time, a new wrench 001 enters the docking part 214 to supplement the vacancy, and so on in a cycle.

[0066] To ensure the smooth dropping of the wrench 001 at the dropping port 213, the trigger 236 rotates synchronously with the rotation of the slat 002 and interacts with the push-back member 235, causing the push-back member 235 to move towards the docking part 214. The height of the push-back member 235 just reaches and presses on the wrench 001 on the docking part 214, ensuring that the wrench 001 in the dropping port 213 is not affected by the thrust from the entire row of wrenches 001. This design enables the smooth conveying and unloading of the wrench 001 in the swinging unloading assembly 23, improving the working efficiency of the automatic packing device for electric tool accessories.

[0067] It should be noted that at the position of the wrench arrangement bin 21 corresponding to the roller 232, the wrench arrangement bin 21 is provided with a notch for the roller 232 to move in and out. The diameter of the elastic pin 234 is much smaller than the diameter of the working part of the wrench 001. The elasticity of the elastic pin 234 lies in its ability to bend and return to a straight state in the radial direction, and the end of the elastic pin 234 has a chamfer. The center distance between the two elastic pins 234 is the same as or close to the center distance between the holes or notches at both ends of the wrench 001. The lengths of the two elastic pins 234 are set such that when the slat 002 is parallel to the end of the wrench arrangement bin 21, the chamfers of the two elastic pins 234 can enter the wrench 001 on the docking part 214, and the parts of the two elastic pins 234 close to the chamfers enter the wrench 001 falling at the dropping port 213. Such a design effectively supports the wrench 001 located at the dropping port 213.

[0068] In addition, to make the elastic pin 234 more smoothly disengage from and re-enter the wrench 001, referring to Figure 9 , a transition block 237 with an annular working surface is added during the stroke of the elastic pin 234 rotating outwards. The transition block 237 plays a role in guiding the elastic pin 234, which helps to ensure that the elastic pin 234 smoothly disengages from and re-enters the wrench 001.

[0069] In addition, considering that the sizes of the two ends of a general wrench 001 usually do not differ much, and the structure of the wrench conveying mechanism 20 performs the supporting and unloading actions based on the centers of the working positions at both ends of the wrench 001, with relatively low precision requirements, that is, having a certain error tolerance range. Therefore, there is generally no direction limit for the wrench 001. This means that the wrench conveying mechanism 20 can, to a certain extent, adapt to wrenches 001 of different shapes and sizes. It also means that the operator does not need to specifically adjust the direction when placing the wrench 001, which can simplify the operation process and improve work efficiency. This characteristic of the wrench conveying mechanism 20 helps to reduce the operation burden of the operator and improve the operation efficiency of the entire system.

[0070] Referring to Figure 1 and Figure 2 , the structure of the conveying frame 12 is similar to a tray. The lower bottom plate is hinged from both sides and opens downward. A torsion spring is provided at the hinge. The opening method in this embodiment is that when the lower bottom plate receives a weight greater than the torsion force of the torsion spring, it opens downward. After opening, the components on the bottom plate fall downward. In further expansion, it can be any opening and closing mechanism with other structures in the prior art. The height of the lower bottom plate of the conveying frame 12 needs to be lower than that of the wrench conveying mechanism 20. At least one collision block 121 for hitting the roller 232 is provided in each conveying frame 12. The collision block 121 needs to be provided at the front end in the advancing direction of the conveying frame 12, so as to ensure that after the second impact, the wrench 001 can fall into the conveying frame 12 when it drops. In this embodiment, the collision block 121 in each conveying frame 12 can be installed at two positions, which is convenient for selecting and installing a collision block 121 in the correct direction according to the moving direction of the conveying frame 12.

[0071] In the present invention, referring to Figure 1 and Figure 2 , the structure of the conveying frame 12 is similar to a tray. The lower bottom plate of the tray is designed to be hinged from both sides and open downward. A torsion spring is provided at the hinge, so that the lower bottom plate opens downward when it receives a weight greater than the torsion force of the torsion spring. When opened, the components on the bottom plate will fall downward. In further expansion, any opening and closing mechanism with other structures in the prior art can be adopted.

[0072] The height of the lower bottom plate of the transfer frame 12 needs to be lower than that of the wrench transfer mechanism 20. In each transfer frame 12, at least one collision block 121 for hitting the roller 232 is provided. The collision block 121 should be arranged at the front end in the forward direction of the transfer frame 12 to ensure that the wrench 001 can fall into the transfer frame 12 after the second impact.

[0073] In this embodiment, the collision block 121 of each transfer frame 12 has two installable positions. Such a design facilitates selecting and installing a collision block 121 in the correct direction according to the moving direction of the transfer frame 12.

[0074] In summary, through the ingenious structural design of the invention and the setting of hitting the roller by the stroke of the transfer frame 12, the rapid and efficient unloading and placing of the wrench are realized, the operation process is simplified, and the work efficiency is improved. At the same time, the design of the transfer frame 12 and the adjustable installation position of the collision block 121 also bring more convenience to the actual operation.

[0075] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
