Description

Steering conveying device

Technical Field

The utility model relates to a conveying equipment especially relates to a turn to conveyor who carries article rotation to different angles.

Background

In an automatic production line, a conveying belt is generally used for conveying articles, the conveying direction of the conveying belt is generally a straight line, when the articles need to be turned to a certain angle to facilitate subsequent processing or packaging, the conveying belts in multiple sections and different directions need to be combined for use, or a special turning track is arranged, but the turning devices need to occupy a large amount of production space, the problems of complex structure, high failure rate, difficult maintenance and the like exist, and the turning precision is difficult to effectively guarantee.

Disclosure of Invention

An object of the utility model is to provide a simple structure and accurate, the stable conveyor that turns to of work to improve article turn to the precision, and reduce the space and occupy required and the cost of manufacturing, maintaining.

The steering conveying device of the utility model comprises two screw rods which are arranged in parallel in the axial direction and driving motors which respectively drive the two screw rods to rotate along opposite directions; the two screws are symmetrically arranged, the screw pitches on the screws gradually increase or decrease from one end to the other end, and a gap for articles to enter the spiral grooves of the two screws is reserved between the two screws.

In the steering conveying device of the utility model, the spiral grooves of the two screws are symmetrically arranged along the axial direction, and the driving motor drives the two screws to rotate along opposite directions, namely one of the screws rotates along the clockwise direction and the other screw rotates along the anticlockwise direction, and simultaneously, the rotating speeds of the two screws are consistent, so that the spiral grooves relatively rotate in the rotating process; when an article enters from one end of the two screw rods, the two screw rods can drive the article to be conveyed out from the other end under the action of the spiral grooves, and in the process, the article is pushed by the spiral grooves and rotates around the direction perpendicular to the axial direction of the screw rods, so that the article can be conveyed in a turning mode, and the turning conveying at different angles of 30 degrees, 60 degrees, 90 degrees and the like can be realized according to the conveying requirement of the article and the setting of specifications such as the length, the thread pitch and the like of the screw rods, so that the conveying requirement of the article can be met. The steering conveying device is simple in structure and small in size, is beneficial to reducing the manufacturing and maintenance cost, and reduces the requirement of occupied space; meanwhile, the steering conveying is carried out by utilizing the characteristics of the screw, the working precision and the stability are extremely high, and the steering precision and the conveying position precision of article conveying are greatly improved.

Detailed Description

A steering conveying device comprises two axially parallel screw rods 1 and driving motors 2 which respectively drive the two screw rods to rotate along opposite directions; the two screws are symmetrically arranged, the screw pitches on the screws gradually increase or decrease from one end to the other end, and a gap for articles to enter the spiral grooves of the two screws is reserved between the two screws.

The steering conveying device is provided with a feeding conveying belt 3 for conveying articles between the two screw rods 1 and a discharging conveying belt 4 for conveying the articles output from the screw rods, and the feeding conveying belt and the discharging conveying belt are respectively arranged at two ends of a gap between the two screw rods so as to meet the requirement of automatic production. In addition, a rack 5 which can be movably and fixedly placed at any place is arranged, the screw rod 1, the driving motor 2, the feeding conveyer belt 3 and the discharging output belt 4 are all arranged on the rack, and the arrangement and the use of the steering conveyer device are more flexible through the arrangement of the structure, so that the steering conveyer device can be conveniently arranged at any needed place to steer and convey articles.

As shown in fig. 1 and 2, for example, rectangular box-shaped articles 10 are conveyed in a 90 ° turn, and the box-shaped articles are conveyed from above to below in fig. 2. The box-shaped product enters between the two screw rods under the drive of the feeding conveyer belt, and the two screw rods rotate along opposite directions under the drive of the drive motor respectively; then, the box-shaped product falls into the spiral groove between the two screws and is driven by the spiral groove to move towards the other end; the box-shaped article is divided into two parts, one part is linearly moved from top to bottom, and the other part is rotated around the direction vertical to the paper surface of figure 2, so that the box-shaped article rotates and translates at the same time; and the box-shaped products are turned at a set angle until the box-shaped products are output from the other end of the screw rod, fall onto the discharging conveyor belt and are conveyed to the subsequent process by the discharging conveyor belt.

In the above turning conveyor device shown in fig. 1 and 2, the screw pitch of the screw gradually increases along the conveying direction, i.e. the screw pitch of the screw gradually increases from top to bottom, and the conveying directions of the feeding conveyor belt and the discharging output belt are also from top to bottom, so that the box-shaped articles which are transversely placed are finally turned by 90 degrees to form longitudinal placement. Similarly, the conveying directions of the feeding conveying belt and the discharging output belt can be set in opposite directions, so that the articles are conveyed from the lower part to the upper part in the figure 2, and at the moment, the screw pitch of the screw is gradually reduced along the conveying direction, so that the box-shaped articles which are originally longitudinally placed are transversely placed. The articles conveyed by the above-described diversion conveyor may be articles of other shapes, such as bottle-shaped articles as shown in fig. 3.

The angle of each rotation of the articles is not too large, preferably between 1 and 20 degrees, and optimally between 10 and 15 degrees, so that the articles are prevented from being damaged or the occurrence of the blocking accident is avoided; in addition, the screw pitch of the screw is 1.2-2.5 times of the length of the article to be turned, when the screw pitch is less than 1.2 times, the gap between the two screws is too narrow, and the article can be extruded during rotation, so that the article is failed to be turned, and even the article is damaged; if the pitch is greater than 2.5 times, the gap between the two screws is too wide, and the screws are likely not to contact and rub with the object to form a steering acting force, thereby causing steering failure.
