Detailed Description

The accompanying drawings, which are incorporated in and constitute a part of this application, illustrate preferred embodiments of the utility model and together with the description, serve to explain the principles of the utility model and not to limit the scope of the utility model.

Referring to fig. 1 to 3 (connection wire harness is not shown in the figures), the present invention provides a preferred embodiment of a continuous sorting system of a packaging machine, the continuous sorting system of the packaging machine comprises a measuring conveyer belt 1 and a detecting component 2, wherein the measuring conveyer belt 1, a conveying surface of the measuring conveyer belt 1 is a continuous elastic surface, and a feeding end of the measuring conveyer belt 1 is connected to a discharging port of the packaging machine. The detection assembly 2 further comprises a mounting plate 21, a deformation detector 22 and an indicator 23, wherein the mounting plate 21 is arranged between the conveying surface and the return surface of the measuring conveyer belt 1 and is parallel to the conveying surface of the measuring conveyer belt 1. The deformation detector 22 is mounted on the mounting plate 21 and is used for detecting and measuring the deformation degree of the conveyor belt 1. The indicator 23 is electrically connected to the deformation detector 22 and is used for displaying the detection information of the deformation detector 22.

This continuous sorting system of packagine machine when using, transports the good product material of packagine machine packing through measuring conveyer belt 1, because of measuring the transportation face of conveyer belt 1 and being the elastic surface, its transportation face can produce decurrent deformation when it bears the weight of material, and the deformation degree alright with reflecting the weight of material fast. The deformation detector 22 is fixed through the mounting plate 21, the deformation detector 22 can be used for detecting and measuring the deformation degree of the conveying surface of the conveying belt 1, and the deformation information is reflected through the indicator 23. People like this through observing indicator 23, alright with knowing whether up to standard the net content of this material, alright with discerning the defective work. Most importantly, in the process of screening unqualified products, the measuring and conveying belt 1 can run uninterruptedly and continuously convey the packed products of the packing machine without stopping the machine for waiting.

The above components will be described in detail below:

the measuring conveyer belt 1 in this embodiment is a carrier for measuring the weight of the material, and is composed of a plurality of parts, such as an elastic conveyer belt, two driving rollers, and supporting legs, wherein the conveyer belt is arranged around the two driving rollers, and the upper surface of the conveyer belt is the conveying surface of the measuring conveyer belt 1. The conveyer belt can be made by elastic material such as PU skin, elastic rubber, and when the material was arranged in on the transportation face, the conveyer belt can the undercut produce deformation, and this deformation degree has then reflected the weight information of material, and sensitive when this deformation action takes place, rapid, can not produce too much delay.

As a preferred embodiment, the length of the stroke of the measuring conveyor belt 1 in this embodiment is greater than the length of one material it conveys, while being less than twice the length of one material it conveys. Therefore, only one material exists on the conveying surface at a time, and the information reflected by the deformation of the material is more accurate. However, since the measuring conveyor 1 is shorter in length, it is recommended in practice to cooperate with other conveyors, such as the preceding conveyor 4 and the following conveyor 5, to achieve a better conveying and sorting effect over a long distance.

As a preferred embodiment, in this embodiment, the mounting plate 21 of the detection assembly 2 is used as a carrier of the deformation detector 22, which is connected to the legs of the measuring conveyer 1 and is disposed between the conveying surface and the return surface of the measuring conveyer 1. Which should be kept at a suitable distance from the transport plane of the measuring conveyor 1 so that the deformation detector 22 can detect the deformation of the measuring conveyor 1.

Referring to fig. 2, as a preferred embodiment, the deformation detector 22 in this embodiment is an infrared distance measuring sensor, and the infrared emission direction of the deformation detector 22 faces and is perpendicular to the conveying surface of the measuring conveyor 1. The infrared distance measuring sensor is a sensing device, is a measuring system using infrared rays as a medium, and has the advantages of wide measuring range and short response time. The infrared distance measuring sensor of the embodiment can detect the distance from the conveying surface of the measuring conveyer belt 1 to the infrared emission end of the measuring conveyer belt 1, so that the sinking information of the conveying surface of the measuring conveyer belt 1 is obtained.

Further, the indicator 23 in this embodiment is a display, which is installed at one side of the measuring conveyer 1 and electrically connected to the deformation detector 22, for displaying the recess information detected by the deformation detector 22 in a reading manner.

It should be noted that the recess information is not necessarily distance information, and only the detection result of the deformation detector 22 needs to be reflected. For example, when the infrared distance measuring sensor does not have the function of data conversion, the voltmeter can be directly used as the display and connected with the result output end of the infrared distance measuring sensor, the voltage change output by the infrared distance measuring sensor is directly displayed through the voltmeter, and the voltage change is equivalent to the measurement of the depression change of the conveying surface of the conveying belt 1, namely the weight information of the material.

Referring again to fig. 3, in a preferred embodiment of the present invention, the detecting assembly 2 of the continuous sorting system of the packaging machine further includes a resilient plate 24. The elastic plate 24 is arranged between the mounting plate 21 and the conveying surface of the measuring conveyer belt 1, one surface of the elastic plate 24 departing from the mounting plate 21 is attached to the conveying surface of the measuring conveyer belt 1, and the deformation detector 22 is arranged between the elastic plate 24 and the mounting plate 21. Because the conveying surface of the measuring conveyer belt 1 is in a motion state all the time, the elastic plate 24 is arranged in the embodiment and is made of materials such as PVC, rubber or polyurethane, the elastic plate can fluctuate along with the conveying surface of the measuring conveyer belt 1, and meanwhile, the deformation detector 22 can detect a stable object which cannot move all the time, so that the detection result is more accurate. In addition, the elastic plate 24 may be provided with a deformation detector 22, such as:

as a preferred embodiment, unlike the previous embodiments, the deformation detector 22 in this embodiment is two contacts, which are respectively mounted on the elastic plate 24 and the mounting plate 21, and are used for contacting when the elastic plate 24 is depressed toward the mounting plate 21. In addition, the detecting assembly 2 in the present embodiment further includes a direct current power source, such as a storage battery (not shown in the figure). The indicator 23 is not a display but an indicator light, and the indicator 23 is mounted on one side of the measuring conveyer 1.

Direct current power supply, deformation detector 22 and pilot lamp are connected the formation return circuit in proper order electricity, and two contacts are just equivalent to the effect of switch this moment, and when material weight reached standard, the sunken certain degree of measuring conveyer belt 1 made two contacts contact, and the return circuit switches on this moment, and the pilot lamp lights, just takes the table material qualified. When the field personnel see that the materials pass through and the indicating lamp is not lighted, the materials can be judged to be unqualified products with unqualified weight, the unqualified products can be removed by adopting corresponding means, and the simplest method is manual taking.

It should be understood that the types of the deformation detector 22 and the indicator 23 in the above two embodiments are only used as two preferred embodiments for illustration, and in practical implementation, other types of components may be used according to practical requirements.

The push rod 3 is used for replacing hands to perform material removing action, and due to the fact that the push rod 3 is spaced from the detection assembly 2, sufficient reaction time is given to field personnel, and unqualified materials are prevented from being missed when the push rod 3 acts.

Further, if an electric push rod or a hydraulic push rod is adopted as the push rod 3 in the embodiment in practical implementation, the control part of the push rod can be electrically connected with the deformation detector 22 or the indicator 23 to realize automatic control, and unqualified materials can be automatically identified and removed without manual monitoring. However, since the height of the surface of the conveyor belt 1 is measured to be periodically and continuously changed, if it is determined that the weight of a material does not meet the standard, the change of the signal waveform needs to be monitored for a period and analyzed, and therefore, a certain time delay is generated between the time when the motion of the push rod 3 is detected by the deformation detector 22. During this time, if the conveyor belt 1 is continuously operated, the defective material will already have passed the position of the detection assembly 2 when the pusher 3 starts to operate.

Therefore, the push rod 3 is arranged in front of the detection component 2 along the conveying direction of the measuring conveyer belt 1, the materials can continue to advance in the delay time from the detection component 2 to the detection that the push rod 3 starts to perform effective action, and when the push rod 3 acts, the unqualified materials just advance to the corresponding position of the push rod 3. So that the whole continuous sorting system of the packing machine can continuously run without stopping the machine and waiting for the action of the push rod 3. In this way, the push rod 3 in this embodiment can operate well, and there is no need to stop the measuring conveyor 1, whether manual or automatic control is used in practice.

While the subsequent conveyor 5 is used to connect the measuring conveyor 1 with the next process, such as cleaning, loading etc. The shortage of the length of the measuring conveyer belt 1 is made up by the pre-conveyer belt 4 and the post-conveyer belt 5, so that the whole continuous sorting system of the packing machine has enough conveying length and certain sorting precision. The pre-conveying belt 4 and the post-conveying belt 5 can be realized by selecting a roller line, a conveying belt and the like according to actual needs, and the utility model does not limit the utility model.

As a preferred embodiment, two posture correcting rails 6 are arranged on the preamble conveying belt 4 in the embodiment, the two posture correcting rails 6 are both parallel to the conveying surface of the preamble conveying belt 4, and the interval between one ends of the two posture correcting rails 6 departing from the measuring conveying belt 1 is gradually increased along the opposite direction of the operation of the preamble conveying belt 4.
