Abstract

The utility model discloses an empty packet detector comprising a roller, a rotating arm, a rotating shaft, a support, a tension spring, an empty packet detection sensor and a sensor bracket. The roller is disposed at one end of the rotating arm. The rotating arm rotates around the rotating shaft. The rotating shaft is fixed on the support. One end of the tension spring is connected to the rotating arm, and the other end of the tension spring is connected with the sensor bracket. The empty packet detection sensor is fixed on the sensor bracket. The sensor bracket is fixed on the support. The roller continuously rolls on a small packet; when the small packet is not empty, inside drug of the small packet allows the roller to leap, and the empty packet detection sensor recognizes the packet as being not empty; when the small packet is empty, the roller never leaps, and the empty packet detection sensor recognizes the packet as being empty. The empty packet detector has the advantages that detection precision is improved, false report rate of empty packets is reduced, and the empty packets can be detected efficiently and automatically.

Description

A kind of empty package detection device

Technical field

The utility model relates to packaging field, particularly a kind of empty package detection device.

Background technology

At present, in the packaging facilities on market, in the medicine bag Kong Bao testing agency of granular preparation, use be substantially all proximity transducer, accuracy of detection is low, easily produces " wrong report " phenomenon, causes sky packet flow to enter follow-up producing process.

Utility model content

The technical problems to be solved in the utility model is exactly the defect that overcomes prior art, proposes a kind of empty package detection device, and whether can realize automatic detection parcel is empty bag.

In order to address the above problem, the utility model provides a kind of empty package detection device, comprise: roller, pivot arm, S. A., support, extension spring, empty bag detecting sensor and sensor support frame, wherein, described roller is positioned at one end of described pivot arm, described pivot arm rotates around S. A., and described S. A. is fixed on support; One end of described extension spring connects described pivot arm, and the other end connects described sensor support frame; Described empty bag detecting sensor is fixed on described sensor support frame, and described sensor support frame is fixed on described support; Described roller continuous rolling on parcel, when parcel non-NULL, has one to jump the work that rolls under the effect of roller medicine in parcel, empty bag detecting sensor is identified as non-NULL bag; When parcel is sky, roller is not jumped to roll and is done, and empty bag detecting sensor is identified as sky bag.

Preferably, described empty package detection device also comprises empty bag detecting sensor baffle plate, and described empty bag detecting sensor baffle plate is positioned at described pivot arm away from one end of roller.

The utility model has improved the precision detecting, and reduces the rate of false alarm of empty bag, and the high-efficient automatic of having realized empty bag detects.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of the empty package detection device of the utility model embodiment;

Wherein, 1-support, 2-pivot arm, 3-empty bag detecting sensor baffle plate, 4-S. A., 5-roller, 6-extension spring, 7-empty bag detecting sensor, 8-sensor support frame.

The specific embodiment

Hereinafter in connection with accompanying drawing, embodiment of the present utility model is elaborated.It should be noted that, in the situation that not conflicting, the embodiment in the application and the feature in embodiment be combination in any mutually.

This device is whether parcel to be had to the testing agency of material.As shown in Figure 1, empty package detection device comprises: support 1, pivot arm 2, empty bag detecting sensor baffle plate 3, S. A. 4, roller 5, extension spring 6, empty bag detecting sensor 7 and sensor support frame 8.

This device is fixed on the side plate of transmission mechanism by support 1.Pivot arm 2 one end are provided with roller 5, parcel moving direction as shown in Figure 1, roller 5 under the pulling force effect of extension spring 6, real-time contact continuous rolling on parcel.Pivot arm 2 rotates around S. A. 4, and S. A. 4 is fixed on support 1.One end of extension spring 6 connects pivot arm 2, other end connecting sensor bracing frame 8.Empty bag detecting sensor 7 is fixed on sensor support frame 8, and pivot arm 2 is equipped with empty bag detecting sensor baffle plate 3 away from one end of roller 5.

In parcel, during non-NULL, have one " jumping is rolled " action under the effect of roller 5 medicine in parcel, empty bag detecting sensor 7 is identified as non-NULL bag;

In parcel, during without medicine, roller 5 does not have " jumping is rolled " action, and this space-time bag detecting sensor 7 is identified as empty bag.

Claims

1. an empty package detection device, it is characterized in that, comprise: roller, pivot arm, S. A., support, extension spring, empty bag detecting sensor and sensor support frame, wherein, described roller is positioned at one end of described pivot arm, described pivot arm rotates around S. A., and described S. A. is fixed on support; One end of described extension spring connects described pivot arm, and the other end connects described sensor support frame; Described empty bag detecting sensor is fixed on described sensor support frame, and described sensor support frame is fixed on described support; Described roller continuous rolling on parcel, when parcel non-NULL, has one to jump the work that rolls under the effect of roller medicine in parcel, empty bag detecting sensor is identified as non-NULL bag; When parcel is sky, roller is not jumped to roll and is done, and empty bag detecting sensor is identified as sky bag.

2. empty package detection device as claimed in claim 1, is characterized in that, also comprises empty bag detecting sensor baffle plate, and described empty bag detecting sensor baffle plate is positioned at described pivot arm away from one end of roller.
