Description

A tank cover conveying buffer device

technical field

The utility model relates to a can lid production equipment, in particular to a can lid conveying buffer device for transferring the can lid from the previous processing procedure to the next processing procedure.

Background technique

In enterprises that produce canned food, tea, food, beverages and other canned packaging products, in the production process of cans, the production process of the can lids (lids) at both ends of the cans is very complicated, from sheet material to molding to packaging. After many processes, the equipment of each process is different, the production speed is also different, and it cannot be connected to the production line. The traditional process is to equip operators at the front and back of each equipment, cover the front, cover the back, and then The porters in the two processes carry out inter-process transportation, so many operators are required to complete the complete production of a cover line, and the labor cost is very high, and the labor intensity is also very high. In order to reduce labor intensity and labor cost, after providing single-process production efficiency, automatic connection production between processes is carried out to improve product competitiveness is the primary task of cap manufacturers at present. Because the equipment of each process is different and the production speed is also different, only one robot transfer system can be set up for automatic in-line production between processes. The transfer system needs to be equipped with the front conveyor belt of the cylindrical cover from the previous process. , it is also necessary to set up the conveyor belt behind the cylindrical cover that enters in the last process, and also to set up a storage system for can cover buffering between the two processes. The storage system is set according to the size of the storage capacity. If the storage capacity is large, the storage system It needs to be set up very large, so a transfer system needs to occupy a large site space, and the manufacturing and maintenance costs are relatively high, which is suitable for cap types and cap production lines with large output.

For the transfer system, generally the front conveyor belt of the cylindrical cover in the previous process is based on the production speed of the previous process, and is associated with the timing control of the previous process. The front conveyor belt of the tubular cover in the subsequent process is based on the production speed of the subsequent process, and is associated with the timing control of the subsequent process. Theoretically, the production speeds of the previous process and the subsequent process are set to be equal. However, due to the separate control of the timing of the preceding and following processes, and it is difficult to achieve the absolute same speed of different motors, in actual production, sometimes the can lids sent by the previous process are 1 more than the can lids required by the subsequent process. -2 pcs/per minute, and sometimes 1-2 pcs/per minute less. If there are too many cans, the arched lid will be squeezed after the accumulation of cans. If there are too few cans, the lid will be broken and the production process will be affected. . Therefore, for those lid-type production lines whose production capacity is not very large and the production speeds of adjacent processes are relatively close but not completely consistent, it is necessary to design a set of can lid conveying buffer devices for better in-line production. of.

Utility model content

The purpose of the utility model is to solve the problem that the accumulation of can lids and extrusion arches or broken lids are easy to occur in the existing can lid line production, which affects the smooth progress of production, and to provide a method that does not cause can lid accumulation and extrusion arches or Cap breaking can ensure the smooth production of can cap conveying buffer device.

The specific technical solution adopted by the utility model to solve the above-mentioned technical problems is that a tank cover conveying buffer device includes a frame, and the left side of the frame is provided with a front conveyor belt of a cylindrical tank cover, and the front conveyor belt is formed by the front Driven by the drive motor; the right side of the frame is equipped with a rear conveyor belt for cylindrical can lids, the rear conveyor belt is driven by the rear drive motor, and a buffer conveyor belt for can lids is set between the front conveyor belt and the rear conveyor belt in the middle of the frame. The buffer conveyor belt is driven by the front drive motor through the speed change wheel. The two ends of the buffer conveyor belt are respectively connected with the front conveyor belt and the rear conveyor belt. There are anti-dumping devices for the lid on both sides. A section of buffer conveyor belt is added between the front and rear conveyor belts. Compared with the front conveyor belt, the buffer conveyor belt has a higher can lid conveying speed, so there is a certain gap between the can lids on the buffer conveyor belt, so that the buffer conveyor belt The number of can lids on the conveyor belt can be increased or decreased, and the can lids have a certain buffer capacity in the section. When the speed of the previous process is faster than that of the subsequent process, the density of the can lids on the buffer conveyor belt increases, and when the speed of the previous process is slower than that of the subsequent process, the density of the can lids on the buffer conveyor belt decreases. In this way, the normal conveying of the can lids will not be affected, and the problem that the can lids are easy to accumulate, extrude the arched lid or break the lid and affect the smooth progress of production is solved in the prior art can lid in-line production. On the other hand, since there is a gap between the can lids on the buffer conveyor belt, it is necessary to install anti-dumping devices on both sides of the buffer conveyor belt to avoid the can lids from toppling over.

Preferably, the length of the buffer conveyor belt is 20% to 30% of the length of the front conveyor belt; the tank cover conveying speed of the buffer conveyor belt is 2 to 5 times of the tank cover conveying speed of the front conveyor belt. The longer the relative length of the buffer conveyor belt and the greater the can lid conveying speed of the buffer conveyor belt relative to the front conveyor belt, the smaller the density of the can lids on the buffer conveyor belt or the larger the gap between the can lids; The transmission error of the process is relatively small, so the length of the buffer conveyor belt is 20% to 30% of the length of the front conveyor belt, and the can cover delivery speed of the buffer conveyor belt is 2 to 5 times the can cover delivery speed of the front conveyor belt. Require.

As preferably, the front conveyor belt and the rear conveyor belt all include two round belts for supporting the cylindrical tank cover and moving at the same speed, the two round belts are arranged on the same height of the frame and the front conveyor belt and the rear conveyor belt The height of the round belts is the same; the buffer conveyor belt consists of two round belts used to support the can lid and move at the same speed, and the two round belts are set at the same height of the frame and their height is lower than that of the front conveyor belt or the rear conveyor belt . Two round belts are set under both sides of the can lid to support the can lid and drive the can lid to move; since the buffer conveyor belt needs to be cross-connected with the front conveyor belt and the rear conveyor belt, the height of the buffer conveyor belt is lower than that of the front conveyor belt And the height of the rear conveyor belt, that is, the two round belts of the buffer conveyor belt are located inside the two round belts of the front conveyor belt and the rear conveyor belt, so that the can lids can be smoothly conveyed without mutual interference at the junction of the conveyor belts. The problem of impact; the junction of the conveyor belt is to use the arc structure at the end of the conveyor belt to transfer the can lid from one conveyor belt to another conveyor belt.

As preferably, the can lid anti-dumping device is a magnetic field generator, and the magnetic field generator is a permanent magnet arranged in pairs up and down on both sides of the buffer conveyor belt. The permanent magnets on both sides have a symmetrical structure, and the upper and lower permanent magnets on the same side of the buffer conveyor The polarity of the magnetic poles is opposite, and the side of the permanent magnet away from the buffer conveyor belt is provided with a magnetic conductive plate; both sides of the buffer conveyor belt are provided with non-magnetic conductive side plates, and the end of the side plate close to the front conveyor belt is bent outward A guide structure is formed, the permanent magnets are arranged on the outside of the side plates, and a support plate of a non-magnetic structure is provided between the upper and lower permanent magnets on the same side of the buffer conveyor belt. For iron can lids, a magnetic field generating device is used, using the principle of magnetic levitation, that is, the two sides of the buffer conveyor belt can generate a magnetic field parallel to the cross-section of the cylindrical can lid, and a lighter iron can lid can be used. Under the action of the magnetic force of the magnetic field, the state parallel to the channel cross section is maintained, so that the iron can lid remains upright and moves under the action of the buffer conveyor belt. The side plate of the buffer conveyor belt plays the role of isolating the can lid from the permanent magnet, preventing the iron can lid from being attracted by the permanent magnet.

As an optional solution, the tank cover anti-dumping device is a vacuum device, and the vacuum device is an air pumping mechanism arranged on both sides of the channel and connected to the air pumping holes. This structure uses airflow to suspend the can lid and keep it upright, suitable for can lids with non-ferrous structure.

The beneficial effect of the utility model is that it effectively solves the problems in the prior art that the can lids are easy to accumulate, extrude the arched lid or break the lid during the in-line production of the can lids, which affects the smooth production. The utility model has the advantages of simple structure, small occupied space, good conveying and buffering effect of the can lid, and high practical value.
