Description
Technical field
This utility model belongs to the detection screening dress before bar packing technique field, more particularly to a kind of packaging for bar
Put.
Background technology
In a kind of production of bar, need to carry out sabot operation to it, the material is club-shaped material, is needed before sabot
It is uploaded into output from streamline to come, and detects whether its diameter meets the requirements, transmitted to packaging for satisfactory
The enterprising luggage disk of device, for the undesirable bar of diameter then needs screening to remove.Existing detection screening plant is main
Using as shown in Fig. 1-2, existing transmission dress band is typically constituted using gap bridge a and conveyer belt, and conveyer belt is generally rolled by two sections
The steel band b that axle d drives, steel band b are the rectangular strip structure in cross section.Bar c is transmitted to one from the gap bridge a for being provided with V-groove
To on steel band b, two steel band b parallel intervals are arranged, its gap is for placing bar c, and bar c is lain in two steel band b
Between gap on when, the bottom (lower side bus) of bar c sinks and stretches out the bottom of top steel band b, i.e., H as shown in Figure 2
Value is more than zero, and the upper surface of steel band b can block the upside (bus) of bar, in order to be arranged on swashing for two steel band b both sides
One planar laser beam f1 that light caliper f sends is laterally (vertical) to pass through bar c, so as to measure the diameter of bar c, and will be straight
Footpath value is recorded.And overproof to diameter bar on the basis of diameter is detected is also needed to before virtual package carries out screening point
From such as only relying on the value of measurement carries out manual screening, and its efficiency is also low, and existing equipment has employing to record overproof bar through swashing
Time t1 after light caliper f calculating the displacement S of its movement, by the displacement S places setting doffer in setting separating
Bar, when bar is detected in the S/v time points after laser diameter measuring instrument f, doffer work, bar falls.It is this
The problem that automatic screening separate mode is present is to must assure that in the transmission at the uniform velocity (v) is stably transmitted bar, is otherwise worked as the time
When reaching S/v time points, doffer will start.However, due to being transmitted using steel band b, steel band b itself has a fixed width
Degree, after long-time is transmitted, the easy sideslips of steel band b, i.e. steel band b are not parallel to each other in the horizontal plane, so as to cause the biography of bar
Unstable, easy clamping stagnation is sent, bar just can not possibly be with a certain constant speed movement or even stuck suddenly, delays overproof bar to reach
The time that doffer starts, now, for doffer, the meeting automatic when setting time is reached may be by normal chi
Very little bar is separated, or device dry running, therefore, when there is putty, mode is rejected in traditional time delay will not be judged
The change of rejecting time, so that rejecting to defective work in inappropriate time, causes certified products disallowable, this separation
Screen that stability requirement of the mode of unqualified bar to whole device is high, structure is more complicated, and effect and bad.
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem, there is provided a kind of bar automatic detection screening plant, should
On the premise of device can steadily be transmitted bar is ensured, automatic detection is carried out to diameter and unqualified bar is rejected.
The technical solution of the utility model is as follows：
A kind of bar automatic detection screening plant, including for transmitting the gap bridge for being provided with V-groove of bar, the gap bridge with
Conveyer belt connects, for detecting the transmitting terminal and receiving terminal of the laser diameter measuring instrument of bar diameter respectively positioned at the both sides of conveyer belt,
The laser diameter measuring instrument can send the planar light beam of the bar on conveyer belt；
The conveyer belt includes the rubber strip of two circular in cross-section be arrangeding in parallel, and bar is located between two rubber strips
Gap on and the two sides up and down of rubber strip are protruded respectively in the both sides up and down of bar, the rubber strip be nested on roller and by
Roller drives, and the laser diameter measuring instrument is provided with the outside of rubber strip；
The outfan side of the rubber strip be sequentially provided with the sensor for countering just to the bar on rubber strip and with pressure
The connected nozzle of contracting source of the gas, the opposite side of the outfan is provided with the waste material box for catching the unqualified bar of nozzle blowout；
The outfan and sensor for countering of laser diameter measuring instrument is connected with the input of PLC, outfan and the control of PLC
The electromagnetic valve of nozzle opening and closing processed is connected, wherein, laser diameter measuring instrument is used for the transmission order signal of the bar for transmitting unqualified diameter,
Sensor for countering is used to be delivered to the transmission order up to the bar before nozzle.
Further, the part of bar protrusion rubber strip upper side accounts for the 2/3 of its cumulative volume, and the puff prot of the nozzle
Just bar is being protruded at the medium position of part of rubber strip upper side.
Further, the roller includes setting the first roller and the second roller, embedding on first roller and the second roller
The groove of set rubber strip is arc groove, and the arc radius of arc groove are identical with the radius of rubber strip, the first roller and the
Second wheel is fixed in same rotating shaft.
Further, the rotating shaft of the roller in the middle part of rubber strip is provided with axle journal, is actively cased with the axle journal described
First roller and the second roller.
The beneficial effects of the utility model：This utility model replaces traditional rectangular using the rubber strip of circular in cross-section
Steel band use as conveyer belt, will not as steel band transmission produce larger friction, rubber strip is nested on roller, can be right
Rubber strip plays a part of guiding, prevents rubber strip sideslip, and transmission is steady；Thus, on the one hand bar uniform motion is made, to ensure
There are certain intervals between each bar, adjacent bar making contact will not be caused because transmitting retardance, so as to also affect
To the counting of sensor for countering；On the other hand bar is avoided to cause laser diameter measuring instrument to be examined because axial location on a moving belt deviates
Survey result inaccurate；Rubber strip is transmitted and organically combined with sensor for countering, PLC and nozzle, it is ensured that this device can be accurately
The unqualified bar of separation screening.
