Abstract
Description
Technical Field
[0001] This utility model relates to equipment for processing spring chains, specifically to a spring chain section buffer feeding device used in the process of processing spring chains. Background Technology
[0002] Ammunition belts are ammunition supply devices used to continuously feed ammunition to machine guns or various fully automatic rapid-fire weapons. They can be divided into disintegrating and non-disintegrating ammunition belts. Non-disintegrating ammunition belts consist of multiple belt links, each with a front and a back. At each end of the front of a belt link is a large swivel and a small swivel, forming a groove between them. Long and short wing plates are located on both sides of the belt link, with several small holes along their edges for insertion. The structure of the belt link is as follows: Figure 1 As shown, the links of the spring chain are fixedly connected to adjacent wing plates by hinges or helical springs, forming a long, non-detachable chain.
[0003] In the processing of spring chains, a continuous supply of spring chain links is required to improve processing efficiency. Currently, the methods for continuous supply of spring chain links include vibratory feeder supply and robotic arm supply. Robotic arm supply requires the spring chain links to be arranged in a specific pattern in advance, and then the robotic arm picks them up and delivers them one by one, which is costly. Vibratory feeder supply can output spring chain links individually in a certain posture, but it is easy for the conveying speed of the spring chain links to be inconsistent with the subsequent processing speed of the spring chain, affecting the continuity of spring chain processing. Therefore, there is an urgent need for a device that can buffer and feed the spring chain links sorted by the vibratory feeder to improve the continuity of spring chain processing. Utility Model Content
[0004] The purpose of this invention is to overcome the problem of continuous feeding of existing spring chain links and to provide a spring chain link buffer feeding device that buffers the sorted spring chain links and continuously feeds them to subsequent processes.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a spring link buffer feeding device, including a buffer component, a picking component, and a pushing component, wherein the buffer component, the picking component, and the pushing component are connected to a controller, characterized in that:
[0006] The buffer component mainly consists of a storage track and a retrieval track. The storage track has an U-shaped cross-section and a guide rail inside. A vibration table is located at the bottom of the storage track. The vibration table vibrates the storage track, causing the spring chain links inside to move forward along the guide rail. A feed inlet is located on one side of the retrieval track, and a vision sensor is located above the feed inlet. The discharge outlet of the storage track is located at the feed inlet of the retrieval track. A guide track is located at the discharge outlet of the retrieval track. The cross-sections of the retrieval track and the guide track are concave. The inner walls on both sides of the retrieval track and the guide track are provided with grooves that match the wing plates of the spring chain links. Guide ports are located on both sides of the guide track, and guide platforms are located at the guide ports.
[0007] The material handling assembly mainly consists of push rod mechanism I and push block I. Push block I is a cuboid. Push rod mechanism I is connected to one end of push block I. Push block I is equipped with a receiving platform. The receiving platform is connected to the guide slide rail to receive the spring chain link. Push rod mechanism I drives the receiving platform from the waiting track into the guide track and connects with the guide platform of the guide port.
[0008] The material pushing assembly mainly consists of push rod mechanism II and push block II. Push block II is a cuboid. Push rod mechanism II is connected to one end of push block II. Push block II is located at the guide port. Push rod mechanism II drives push block II to push out the spring chain link on the guide table.
[0009] Optionally, the push rod mechanism I and push rod mechanism II are electric push rods.
[0010] Optionally, the bottom surface of the push block II is provided with a groove that matches the guide platform, and the front end of the push block II is provided with a push part that contacts the small retaining ring of the spring chain link.
[0011] Optionally, each of the pusher block I and pusher block II is matched with a position sensor, and the position sensor detects the displacement distance of pusher block I and pusher block II.
[0012] The operating process and principle of this utility model: This device is generally used in conjunction with a vibratory feeder. The vibratory feeder outputs the spring links with their front facing laterally, and they enter the storage track by vibration. Under the vibration of the vibratory feeder, the spring links move forward along the guide rail in the storage track and arrive at the discharge port of the waiting track. They then enter the waiting track through the receiving platform of push block I. The receiving platform inserts into the groove on the front of the spring link. At this time, the storage track buffers a portion of the sorted spring links. When the vision sensor above the discharge port of the waiting track detects that the spring links have arrived, the vibratory feeder stops vibrating. Under the action of push rod mechanism I, the receiving platform moves forward... The spring chain enters the guide rail and arrives at the push port of the guide rail. The wing plate of the spring chain is placed on the guide platform. The receiving platform docks with the guide platform. Under the action of push rod mechanism II, push block II pushes the spring chain on the guide platform to the next process. Then it returns to its original position. Under the action of push rod mechanism I, the receiving platform returns to the outlet of the waiting track. After receiving the material demand information of the subsequent process, the vision sensor above the outlet of the waiting track detects whether there is material on the receiving platform. When there is no material, the vibrating table starts to vibrate. The spring chain in the storage track enters the waiting track through the receiving platform of push block I. Through the above reciprocating action, material is continuously supplied to the subsequent process.
[0013] Compared with the prior art, the present invention has at least the following beneficial effects: the present invention can effectively improve the continuity of spring chain processing by using the buffer feeding of the spring chain links. Attached Figure Description
