Description

Technical Field

[0001] The utility model relates to a feeding device, in particular to an automatic feeding device for hinge rivets. Background Art

[0002] Hinges are widely used in furniture, electronic equipment and other industries. With the improvement of industrial automation level, the automatic production equipment of hinges has become popular. However, most of the existing hinges need to use rivets, and the automatic sorting and feeding device of rivets is an indispensable part of the production line. Most of the rivet feeding mechanisms in the prior art adopt the whole string feeding method. Although this method can improve production efficiency to a certain extent, it still has some significant shortcomings.

[0003] 1. Lack of single-piece feeding function. Most existing rivet feeding mechanisms use a whole bunch feeding method, that is, a whole bunch of rivets is fed to the next process through a feeding pipe. Although this method can transport a large number of rivets in a short time, due to the lack of single-piece feeding function, an additional dividing mechanism is required to separate the whole bunch of rivets into single pieces for operation when the rivets are installed on the product. This not only increases the complexity of the equipment, but may also cause the rivets to jam and be damaged during the dividing process.

[0004] 2. The additional material separation mechanism increases the complexity of production. Since the whole string feeding requires an additional material separation mechanism to separate the rivets into individual ones, it increases the complexity of the production line and the difficulty of maintenance. These material separation mechanisms are usually complex in structure, with many parts and compact arrangement, which makes maintenance and repair more difficult. In addition, the additional material separation process increases the residence time of the rivets in the production line, affecting the overall production efficiency.

[0005] 3. High energy consumption and maintenance costs. The whole string feeding plus the additional material distribution mechanism not only increases the energy consumption of the equipment, but also increases the maintenance cost. Frequent start and stop operations and complex mechanical moving parts lead to high energy consumption during the operation of the equipment, which is not conducive to energy conservation and emission reduction. At the same time, the complex material distribution mechanism is prone to wear and failure after long-term use, requiring frequent maintenance and repair, which increases production costs.

[0006] In summary, the lack of single-piece feeding function in the prior art rivet feeding mechanism leads to problems such as increased production complexity, insufficient material separation accuracy and stability, high energy consumption and high maintenance cost. Therefore, it is necessary to make further improvements thereto. Utility Model Content

[0029] The utility model is further described in detail below with reference to the accompanying drawings. An automatic feeding device for hinge rivets comprises a vibrating feeding tray 1, the discharge port of the vibrating feeding tray 1 is connected to a discharge pipe 11, and the rivets 2 sorted by the vibrating feeding tray 1 enter the discharge pipe 11 in order of direction;

[0030] The dividing seat 3 also includes a dividing channel 31 which runs vertically through the main body of the dividing seat 3. The inlet end of the dividing channel 31 is connected to the discharge pipe 11, and the outlet end of the dividing channel 31 is connected to the feed pipe. The dividing seat 3 is laterally provided with a dividing ejector pin 4 and a discharge ejector pin 5. The dividing ejector pin 4 and the discharge ejector pin 5 are spaced apart from each other in the upper and lower parts, and are driven to move by a power mechanism, so that the dividing ejector pin 4 and the discharge ejector pin 5 enter and exit the dividing channel 31, and block or release the rivet 2 located in the dividing channel 31.

[0031] In one of the embodiments: a dividing hole 32 and a discharging hole 33 are horizontally arranged on the dividing seat 3, the dividing hole 32 and the discharging hole 33 are vertically arranged and penetrate the dividing channel 31, the dividing ejector pin 4 is slidably installed in the dividing hole 32, and the discharging ejector pin 5 is slidably installed in the discharging hole 33.

[0032] In one embodiment, the material distribution hole 32 and the material discharge hole 33 are staggered in the upper and lower parts, and the distance between them is greater than the length of the rivet.

[0033] In one embodiment, the material distribution hole 32 and the material discharge hole 33 are arranged on the left and right sides of the material distribution seat 3, so that the material distribution ejector pin 4 and the material discharge ejector pin 5 are installed in opposite directions.

[0034] In one embodiment, the power mechanism is a cylinder 6, which is connected to the material distribution ejector 4 and the material discharge ejector 5 through a connecting frame 7 to drive them to move.

[0035] In one of the embodiments: the connecting frame 7 includes a guide rod 71 and a cylinder seat 72 and a connecting seat 73 located at both ends thereof, a guide hole 74 is horizontally arranged on the material distribution seat 3, the guide rod 71 is slidably installed in the guide hole 74, one end of the connecting seat 73 is connected to the material distribution ejector 4, and one end of the cylinder seat 72 is connected to the discharge ejector 5 and the cylinder 6.

[0036] In one embodiment, the side wall of the distribution channel 31 is further provided with an upper air blowing channel 34 obliquely downward, and the upper air blowing channel 34 is connected to an upper air blowing pipe 35 .

[0037] In one embodiment, the connecting point between the upper blowing channel 34 and the material distribution channel 31 is located between the material distribution ejector pin 4 and the material discharge ejector pin 5 .

[0038] In one embodiment: the bottom of the distribution channel 31 is connected to a discharge seat 8, a discharge channel 81 is arranged in the discharge seat 8 and docked with the distribution channel 31, and a lower blowing channel 82 is also arranged obliquely downward on the side wall of the distribution channel 31, and the lower blowing channel 82 is connected to a lower blowing pipe 83.

[0039] Working principle: In this case, before use, rivets are manually introduced into the vibrating feeding tray 1, and the vibrating feeding tray 1 arranges the messy rivets 2 into an orderly arrangement through vibration and feeds them into the discharge port. The rivets enter the discharge pipe 11 in the order of direction. This method ensures the orderly arrangement of the rivets and improves the accuracy of subsequent material distribution.

[0040] The discharge pipe 11 delivers the orderly arranged rivets to the distribution seat 3, and a distribution channel 31 is vertically arranged in the distribution seat 3 and penetrates the body thereof. The inlet end of the distribution channel 31 is connected to the discharge pipe 11, and the rivets enter the distribution channel through the discharge pipe and enter the bottom of the distribution channel under the action of their own weight.

[0041] Among them, a material distribution ejector pin 4 and a material discharging ejector pin 5 are horizontally installed on the material distribution seat 3. The material distribution ejector pin and the material discharging ejector pin are spaced apart from each other and driven to move by a power mechanism. The power mechanism is usually a cylinder 6, which is respectively connected to the material distribution ejector pin and the material discharging ejector pin through a connecting frame 7 and drives them to move. The material distribution ejector pin and the material discharging ejector pin enter and exit the material distribution channel, block or release the rivets located in the material distribution channel, thereby realizing the single precise distribution of rivets.

[0042] Among them, a material distribution hole 32 and a material discharge hole 33 are horizontally arranged on the material distribution seat 3, and the two are arranged vertically and through the material distribution channel. The material distribution ejector is slidably installed in the material distribution hole, and the material discharge ejector is slidably installed in the material discharge hole. The material distribution hole and the material discharge hole are staggered up and down, and the distance between the two is greater than the length of the rivet, ensuring that the material distribution ejector and the material discharge ejector act on the upper and lower rivets respectively during the material distribution and feeding process.

[0043] like Figure 6 , 7 As shown, under normal conditions, the discharge ejector is inserted into the distribution channel to prevent the rivet at the bottom from falling down. When the rivet at the bottom needs to be supplied, the discharge ejector retracts. At the same time, the distribution ejector extends and presses on the side wall of the second rivet to fix it. When the distribution ejector is separated from the distribution channel, the rivet at the bottom falls out from the bottom of the distribution channel to realize the single rivet feeding. Then the discharge ejector is reset and reinserted into the distribution channel. At the same time, the distribution ejector withdraws from the distribution channel, and the rivet at the bottom falls down and is restricted by the discharge ejector without falling from the distribution channel. After the above steps are repeated, through the cooperation of the discharge ejector and the distribution ejector, the device can only supply one rivet at a time, thereby realizing the automatic distribution operation of rivets.

[0044] The side wall of the material distribution channel is also obliquely downwardly provided with an upper air blowing channel 34 and a lower air blowing channel 82. The upper air blowing channel is connected by an upper air blowing pipe 35, and the lower air blowing channel is connected by a lower air blowing pipe 83. During the material distribution and feeding process, air flow can be provided to clear the rivet blockage that may exist in the material distribution channel, ensuring the continuity and stability of the feeding process.

[0045] Compared with traditional technology, this device realizes orderly arrangement and single-piece distribution of rivets through the cooperation of vibrating feeding plate and distribution seat, avoids the disadvantage that an additional distribution mechanism is required for the whole string of rivets, and improves the accuracy and efficiency of distribution and feeding.

[0046] In addition, the dividing and discharging ejector pins are driven by cylinders and achieve precise synchronous movement through the connecting frame, ensuring the accurate positioning and release of the rivets in the dividing channel, realizing efficient, precise and stable single rivet dividing and feeding, so it can be widely promoted and used.

[0047] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
