Abstract

The utility model discloses a conveying device capable of evenly separating products. The conveying device comprises a conveyor belt (10), a drive motor (12) and a control unit (20). The control unit comprises a frequency converter (22), a sensor (24) and a programmable logic controller (26). The frequency converter can adjust the rotation speed of the drive motor, and the sensor can output a signal (S1) about the number of the products. The programmable logic controller is provided with an input end (260), a first output end (262) and a second output end (264). The programmable logic controller compares the signal about the number of the products with a preset value; if the signal is equal to the preset value, the first output end outputs an interval acceleration instruction to the frequency converter, and the second output end outputs a count reset signal to the sensor. In this way, the products in the conveyor belt are evenly separated into groups, an obvious interval is formed between every two adjacent groups, encasement operators can easily encase products with the fixed number into boxes, and the encasement speed and efficiency are improved.

Description

The conveyer that article evenly can be separated

Technical field

The utility model relates to the conveyer that transmits article, particularly a kind of belt conveyor that article evenly can be separated by certain quantity.

Background technology

The belt conveyor of workshop all travels at the uniform speed at present, article are fallen on belt feeder the vanning district that travels at the uniform speed one by one out from wrapping machine, packer takes off article from belt conveyor and cases, the product that crater takes off same number from belt conveyor packs in packing chest, not only require the skilled of operative employee but also require crater will remember accurately the number of Chu's product, this working strength for crater is very large.

Summary of the invention

The purpose of this utility model is to provide a kind of conveyer that article evenly can be separated, the speed of the change belt conveyor that it can pass through, article on belt conveyor are evenly separated by some, even have obvious space to cut apart in the middle of the article of fixed qty, vanning personnel are easy to identify objects number like this, facilitate article vanning.

The utility model provides the conveyer that article evenly can be separated, it comprises a belt conveyor, a drive motor that can drive belt conveyor, with a control unit, control unit comprises a frequency converter, a sensor, with a programmable logic controller (PLC), the rotating speed of frequency converter capable of regulating drive motor, sensor can and be exported a number of articles signal to the transporting articles number count on belt conveyor, programmable logic controller (PLC) has an input end that can receive article number signal, first mouth that frequency converter can be electrically connected, with second mouth that can be electrically connected with sensor.Programmable logic controller is compared number of articles signal with a preset value, if number of articles signal equals this preset value, the first mouth is exported an intermittently assisted instruction to frequency converter, and the second mouth is to counting reset signal of sensor output.

In the another kind of exemplary embodiment of the conveyer that article evenly can be separated, sensor is opto-electronic pickup.

The conveyer that article evenly can be separated can make the article that drop on belt conveyor divide into groups equably by preset value, between each group, formed obvious interval, vanning personnel can, very like a cork by the packaging products in boxes of fixed qty, improve speed and the efficiency of vanning.

The specific embodiment

For technical characterictic, object and the effect of invention are had more clearly and are understood, now contrast accompanying drawing the specific embodiment of the present utility model is described, accompanying drawing is only for helping to understand the utility model, the not practical structures of representative products and truly ratio, in each figure, identical label represents identical part.

In this article, " schematically " expression " is served as example, example or explanation ", any diagram, the embodiment that are described in this article " schematically " should be interpreted as a kind of preferred or have more the technical scheme of advantage.In this article, " one " not only represents " only this ", also can represent the situation of " more than one ".In this article, " first ", " second " etc. are only for differentiation each other, but not represent their significance level and order etc.

Figure 1 shows that a kind of exemplary embodiment of the conveyer that article evenly can be separated, conveyer comprises belt conveyor 10, drive motor 12 and control unit 20, drive motor 12 drives belt conveyor 10 to rotate, and the article 30 from article outlet 14 are transmitted along the direction shown in arrow in figure.

Control unit 20 comprises a frequency converter 22, sensor 24 and a programmable logic controller (PLC) (PLC) 26.Frequency converter 22 is connected with drive motor, the rotating speed of capable of regulating drive motor 12.Sensor 24 can be to the transporting articles 30 on belt conveyor 10 number count, and export a number of articles signal S1.Programmable logic controller (PLC) 26 has 260, one first mouths 262 that can be electrically connected with frequency converter 22 of input end that can receive article number signal S1, and second mouth 264 that can be electrically connected with sensor 24." electric connection " as herein described comprises the various connection modes that can realize signal transmission, as signal transmission forms such as electricity or light.

Programmable logic controller 26 is compared number of articles signal S1 with preset value, if number of articles signal S1 equals preset value, (for example one case ice cream is 30, this preset value is 30), the first mouth 262 is exported an intermittently assisted instruction S2 to frequency converter 22, and the second mouth 264 is to counting reset signal S3 of sensor 24 output.Intermittently assisted instruction S2 can make motor faster rotational speed in a predetermined time interval, it will be understood by those skilled in the art that this time gap need be less than two article 30 successively from article outlet 14 time gaps of sending.

During the rotating speed of drive motor 12 is intermittently accelerated, the transfer rate of belt conveyor 10 is also accelerated thereupon, and the former distance of article 30 and its now dropping on belt conveyor 10 increases, and the counting zero clearing of sensor 24.Along with intermittently adding fast process, finish, after drive motor 12 rotating speeds recover normally, it is normal that also recover thereupon at the interval that article are 30, and 24 pairs of number of articles that fall on belt conveyor 10 of sensor start again to count.This process constantly circulates, and the article 30 that drop on like this on belt conveyor 10 just can divide into groups equably by preset value, has formed obvious interval between each group, and vanning personnel can, very like a cork by the packaging products in boxes of fixed qty, improve speed and the efficiency of vanning.

In the another kind of exemplary embodiment of the conveyer that article evenly can be separated, sensor 24 can be a kind of opto-electronic pickup.

Listed a series of detailed description is above only illustrating for feasibility embodiment of the present utility model; they are not in order to limit protection domain of the present utility model; allly do not depart from equivalent embodiment or the change that the utility model skill spirit is done; as the combination of feature, cut apart or repeat, within all should being included in protection domain of the present utility model.
