Description

A transport and distribution platform for logistics distribution

technical field

The invention relates to the technical field of logistics distribution, in particular to a delivery and distribution platform for logistics distribution.

Background technique

With the rapid development of logistics business, the traditional manual sorting method is gradually being replaced by the automated logistics delivery and sorting platform. The balance wheel sorting platform is one of them. The balance wheel sorting platform has less restrictions on the weight and volume of the package. , and the investment cost is low, the later maintenance cost is low, and the weight of the diverted goods can reach up to 60KG, so the balance wheel diversion platform is favored by many logistics diversion stations.

The balance wheel sorter is a common equipment for the balance wheel sorting platform. The balance wheel sorter is mainly divided into two types. At the beginning, the line pendulum sorter was used, and then the modular pendulum sorter was gradually developed. Wheel sorter, modular balance wheel sorter Although the later equipment maintenance is convenient, each module is equipped with a driving element, which makes the input cost and maintenance cost of the modular balance wheel sorter relatively high, and most users now Line pendulum sorters are still in use;

The pendulum type balance wheel sorter is mainly composed of a frame, rollers, steering controller, transmission device and other structures. During operation, according to the instructions and information issued by the management system, the steering controller changes the running direction of the conveying rollers, which can realize Items are sorted on the left and right sides, and the items are transferred to the diverted conveyor. The transmission device drives the rollers to rotate through the belt, and the rollers need to swing to change the running direction of the rollers. During this process, the belt will be twisted and elongated by 3-5cm. When the wheeled sorting platform is sorting small objects, the single-machine sorting speed can reach up to 4000-5000 pieces/hour, the belt will be stretched 4000-5000 times per hour, and the belt will be stretched and contracted at high frequency, so that the belt will Irreversible plastic deformation will occur within 15-30 days, and the belt will be completely elongated. After the belt is stretched, the pre-tightening force will be insufficient during the driving process and it will slip and affect the transmission of the goods, making it impossible for the goods to be smoothly diverted, resulting in the diversion of the goods Wrong, so when using the pendulum type balance wheel sorter, the belt needs to be replaced frequently to ensure the normal operation of the equipment. The time for a line pendulum type balance wheel sorter to replace the belt is about 30-40 minutes. However, the general sorting platform has more than ten line-swing balance wheel sorters, which consumes a lot of time in equipment maintenance and greatly increases the maintenance cost of the equipment.

For this reason, in order to reduce the deformation of the belt, prolong the life of the belt, and reduce the cost and frequency of equipment maintenance, a transport and distribution platform for logistics distribution is proposed.

Contents of the invention

The purpose of the present invention is to provide a delivery and diversion platform for logistics distribution. By setting the adjustment device and connecting the drive assembly with the fixed frame, the adjustment assembly is driven to loosen the belt when the roller swings, so that the belt stretches after the roller swings. In 0-1cm, to solve the problems raised in the above-mentioned background technology.

To achieve the above object, the present invention provides the following technical solutions:

A transportation and distribution platform for logistics distribution, including a mounting frame 1 and a mounting frame 2, the mounting frame 2 is arranged above the mounting frame 1, and a plurality of driving shafts are mounted on the mounting frame 1 through a vertical bearing with a seat for rotation , one side of the installation frame one is equipped with a drive motor through bolts, the drive motor is connected to the drive shaft on one side of the drive motor through a belt transmission, and the two adjacent drive shafts are connected through a belt transmission, the Mounting frame two is provided with a plurality of rotating devices, and the rotating device can be a rotating cylinder or a rotating electric cylinder. The rotating device is fixed with a fixed frame by bolts, and the rollers are fixed on the fixed frame by bolts. The roller is glued and fixed with lagging, and the lagging material is anti-skid and wear-resistant rubber, such as chlorinated nitrile rubber. The drive shaft and the roller are connected through a belt drive, and the second mounting bracket is equipped with a shell through screws. Said installation frame two is provided with the adjustment device that avoids belt elongation.

When in use, the drive motor rotates, and the drive shaft is driven to rotate through the belt transmission. The adjacent drive shafts are connected in pairs through the belt transmission, so that one drive motor can drive multiple drive shafts to rotate and realize speed synchronization. The drive shaft passes through the belt and the rollers. Connection, the rotation of the drive shaft drives the rollers to rotate. The speed of the drive shaft is the same, and the speed of multiple rollers is also the same. When the goods arrive at the diversion platform, the system will detect and judge whether the goods need to enter the diversion port. When it is judged that the goods enter the left side The diversion port, the system will control the rotating device to rotate 45° clockwise. After the goods arrive at the diversion platform, the conveying direction will be inclined to the left by 45°, and the objects will flow into the left diversion port. When it is judged that the goods enter the right For the side diverter, the system will control the rotating device to rotate 45° counterclockwise. After the goods reach the diversion platform, the conveying direction will be inclined to the right by 45°, and the objects will flow into the right diverter. When it is judged that the goods are in When the two diversion ports do not need to divert, the rotating device will not rotate, and the objects will continue to flow to other diverting ports. According to the system, it is judged whether the objects need to be diverted and the rotation of the rotating device is controlled to change the conveying direction of the objects. Flow to the diversion ports on the left and right sides, so as to realize the diversion of the goods.

Preferably, the adjustment device includes a roller and a connecting rod, the connecting rod is hinged to the mounting frame, the connecting rod is provided with a connecting frame, the roller is connected to the connecting frame by bolts, and the connecting rod is connected to There are drive components;

The driving assembly includes a rotating cylinder and a driving rod, the rotating cylinder is welded on a fixed frame, a chute is arranged on the rotating cylinder, the shape of the chute is V-shaped, the driving rod is hinged to the connecting rod, A spherical slider cooperating with the chute is hinged on the drive rod;

The bottom of the chute is set in an arc shape;

A plurality of balls are rolled and inlaid inside the chute.

When in use, the connecting rod is installed obliquely, and the belt is pushed by the roller to make the belt tight. The drum is fixed on the fixed frame, and the connecting rod and the mounting frame are hinged. The rod is hinged and does not have a horizontal degree of freedom. When the drum rotates, the slider moves vertically up and down under the push of the chute, thereby driving the drive rod to swing. After the drum rotates 45°, the drive rod and the vertical The inclination angle of the direction changes, thereby driving the inclination of the roller and the vertical direction to change. During the rotation of the rotating device, the belt will be twisted and has a tendency to be elongated, while the driving rod drives the connecting rod to swing upwards, and the roller gradually Far away from the belt, the belt has a tendency to relax, which in turn counteracts the belt elongation tendency, thereby solving the problem that the belt is elongated many times during work and the belt life is reduced.

When two consecutive items need to be diverted to the diverting ports on both sides, the roller will swing to the other side after swinging to one side. During the swinging process, the slider is first pushed by the upper wall of the chute, and then becomes The thrust of the lower wall of the chute. During this process, the force of the slider below the chute is prone to fusion and damage the connecting block. By setting the bottom of the chute as an arc shape, when the slider reaches the bottom of the chute, the chute will The thrust of the slider gradually decreases. After entering the chute on the other side, the lower wall of the chute generates a thrust on the slider, and the thrust gradually increases, so as to avoid sudden changes in the thrust of the slider when it is under the chute;

By rolling and inlaying multiple balls inside the chute, the sliding friction between the chute and the slider becomes rolling friction, reducing the wear between the slider and the chute, and improving the service life of the parts;

Since the chute is a V-shaped groove, when the slider and the chute are worn, the contact surface between the slider and the chute remains unchanged, which will cause rapid wear on the part of the slider surface that is in contact with the chute. On the connecting block, the slider rotates during the sliding process of the slider, which changes the contact surface between the slider surface and the chute, so that the surface of the slider can wear with the chute, thereby avoiding local wear of the slider , the slider is rotated and installed on the connecting block, and the slider rotates when it moves in the chute, so that the sliding friction between the slider and the chute becomes rolling friction, thereby reducing the friction between the slider and the chute.

The connecting rod includes a movable rod and a fixed rod, and the fixed rod is hinged to the mounting frame. A pin that cooperates with the jack is installed.

The belt will be stretched after a long time of use. By setting the connecting rod as a fixed rod and a movable rod, the movable rod will be pulled out after the belt is stretched. The movable rod is fixed in the hole, so as to realize the pre-tightening of the belt after it is elongated.

Preferably, the diameter of the roller is 5-7cm, and the roller is an arc-shaped roller inclined from the middle to both sides;

The belt will swing to both sides during the rotation of the roller. The diameter of the roller is usually 4-6cm. During the swinging process of the roller, the maximum deviation of the belt to both sides is 2-3cm, and the width of the belt is between 0.4-1cm. The range of motion is between 4.4-7cm. In order to prevent the belt from shifting and detaching from the roller during the swing of the roller, the length of the roller is set to 5-7cm;

When the roller swings, the belt will have a certain twist, but by setting the roller, the belt between the roller and the drive will not be twisted, and the belt between the roller and the roller will be twisted, which will increase the deformation of the twisted belt. When the belt rotates to the section from the roller to the drum, the length of the belt will fuse, and the increase of the belt twist will lead to an increase in the deformation of the belt, which will aggravate the life loss of the belt. The belts from the drive shaft to the rollers will be elongated when the belts swing, but the amount of elongation is small, and the deformation of the belts will not produce large fusion.

Preferably, the roller can be located inside or outside the belt;

When the roller is on the inner side of the belt, the connecting rod is inclined upwards to stretch the belt to play the role of tensioning the belt. At this time, the contact surface between the belt and the roller will be reduced, and the belt is easy to slip. It is suitable for the diversion of lighter cargo. When it is on the outside, the connecting rod is inclined downward, and the belt is tensioned by pulling the belt back. At this time, the contact surface between the belt and the roller is large, and the belt is not easy to slip relative to the roller on the inner side of the belt, so it can divert larger items, but The adjustment after the belt is stretched will be affected by the space. The distance between the belt and the mounting frame 2 is relatively short, and the tightening of the belt by the roller requires the shortening of the connecting rod. The belt takes too much adjustment.

Compared with prior art, the beneficial effect of the present invention is:

1. A delivery and distribution platform for logistics distribution according to the present invention is provided with an adjustment device and connected to the fixed frame through the drive assembly, which drives the adjustment assembly to loosen the belt when the rollers swing, so that the belt stretches after the rollers swing The amount is 0-1cm, which reduces the deformation of the belt during the swing of the roller, prolongs the service life of the belt and reduces the maintenance frequency.

2. A kind of delivery distribution platform for logistics distribution according to the present invention, by dividing the connecting rod into a fixed rod and a movable rod, by arranging a block on the movable rod and setting a plurality of blocks that cooperate with the block on the fixed rod One bayonet, the position of the block can be adjusted after the belt is deformed for a long time, so that the movable rod can tighten the belt, improve the utilization rate of the belt, prolong the service time of the belt, and reduce the maintenance frequency.

3. A kind of conveying and distribution platform for logistics distribution according to the present invention, by rolling and inlaying a plurality of balls inside the chute, and rotating and installing the slider on the connecting block, when working, the gap between the slider and the chute The friction force changes from sliding friction to rolling friction, effectively reducing the wear between the slider and the chute, and during the friction between the slider and the chute, the slider will rotate, so that the surface of the slider can be in contact with the chute, It avoids the local wear of the slider and reduces the life of the slider.
