Description

Ice cream sticks lateral bending testing agency and the ice cream sticks detection and selection machine that is provided with this mechanism

One, technical field

The utility model relates to woodwork in-process measurement utensil, particularly a kind of ice cream sticks detection and selection machine that is used to measure the testing agency of ice cream sticks lateral bending (side camber) and is provided with this mechanism.

Two, background technology

Along with the raising of ice-lolly production automation degree, also more and more higher to the requirement of ice cream sticks external dimensions standard.The automatic detection and selection machine of various ice cream sticks of public use at present is exactly at the quality requirements of ice-lolly manufacturing enterprise to ice cream sticks, respectively the machine that the defective ice cream sticks of index such as width, thickness, vertical curved and lateral bending are detected and reject.

Detect at the ice cream sticks lateral bending, the ZL200520094755.3 Chinese patent had once disclosed a kind of ice cream sticks lateral bending testing agency and had been provided with the ice cream sticks detection and selection machine of this testing agency, wherein lateral bending testing agency comprises front feeding chain and the back feeding chain that overlaps with the front feeding chain rear portion, preceding back feeding chain forms upright material assembly relation, promptly when the chain wing (this patent is called the feeding tooth) of front feeding chain advances to chain wing intersection with back feeding chain, the forward position of the back feeding chain chain wing just and the contained material of the front feeding chain chain wing (be ice cream sticks, back edge down together) touches mutually, and in continuing traveling process with material jack-up, edge-on behind the back feeding chain chain wing forward position and the corresponding chain wing of front feeding chain along in the gap that forms; On front feeding chain that overlaps and back feeding chain, the material reference platform is arranged, be used for detecting the emitter of photoelectric sensor of material side camber and the two ends that receiving pole is installed in the gate-type bearing of crossing over reference platform respectively.There are following three shortcomings in actual use in this lateral bending testing agency:

First shortcoming is that debugging difficulty is big, and accuracy of detection is low.Main cause is that this mechanism adopts and directly acts on the light that photoelectric sensor sends with tested material and get detection signal, and the debugging of machine is finished by the upper-lower position at adjustment photoelectric sensor the two poles of the earth.Find in the debug process; the ice cream sticks standard specimen that will have lateral bending places tested position; near when lateral bending apart from a utmost point (as emitter), apart from another utmost point (as receiving pole) when far away; set up behind the upper-lower position of sensor the two poles of the earth again the same ice cream sticks direction (make lateral bending near, far away) that swaps round apart from emitter apart from receiving pole; the sensor of originally modulated good the two poles of the earth upper-lower position usually can provide opposite testing result; illustrate that original position, the two poles of the earth of setting up is improper, need again row to adjust.Ice cream sticks direction and position, the two poles of the earth are changed in anti-reflex like this with going, and it is no longer very difficult with the position, the two poles of the earth that the ice cream sticks direction changes to obtain testing result, even not possible, and the accuracy of detection of machine can not be debugged very high.

Second shortcoming be to use shut down in the ice cream sticks detection and selection machine operational process of this mechanism frequent.Main cause is that photoelectric sensor the two poles of the earth of this testing agency are positioned at beyond the defeated material chain, stops light for avoiding the chain wing, and the height of the chain wing is restricted, and promptly can not exceed the width (generally than low 2 to 4 millimeters of material upper side edge) of material.So, material can not all abut on the two chain wings, do not have before and after some and rely on, material is not felt at ease or when material bottom lateral bending upwards arched upward it greatly, this part that can make material lose dependence became big, the material astasia when taking place, in high-speed travel and being subjected under the vibration situation, be easy to fall chain wing top, cause fault for operating machine from upwards overflowing between the two chain wings.For this reason, this machine is provided with the safety switch that monitors that material is overflowed, in case there is material to overflow, even safety switch is shut down.Because this machine material effusion phenomenon is frequent, the shutdown of machine is also just frequent.Frequent shutdown will inevitably make the work efficiency of detection and selection machine reduce, when serious even influence the normal use of machine.

The 3rd shortcoming is this mechanism's false drop rate height.Analyzing its reason has two: one, and the material that stands between the two chain wings is subjected to various condition effect, can not accomplish each and every one the bottom reference platform that can both recline when entering the detection position.For example, when the chain wing because of contamination by dust or be stained with grease when smooth inadequately, the material bottom that has will be unsettled, whole material raises, even be certified products, also can be when tested because of stopping that light is regarded as unacceptable product and is rejected; The 2nd, some sides have tiny burr but do not influence the certified products (especially to the blank material) of use, can Yin Maoci when tested stop light and are regarded as unacceptable product and are rejected.

Three, utility model content

The purpose of this utility model be the shortcoming at above-mentioned prior art provide a kind of debug simple, accuracy of detection is high, can not cause frequent shutdown, ice cream sticks lateral bending testing agency that false drop rate is low and be provided with the ice cream sticks detection and selection machine of this testing agency.

At the reason that causes above-mentioned prior art shortcoming, design philosophy of the present utility model is to directly act on photoelectric sensor institute isolychn by tested material, and pass through the intermediate member indirectly-acting in photoelectric sensor institute isolychn, thereby eliminate the shortcoming of above-mentioned prior art with tested material.

What the ice cream sticks lateral bending testing agency that the utility model provides was identical with above-mentioned prior art is: back feeding chain overlaps with the rear portion of front feeding chain, and forms described upright material assembly relation, is provided with the material reference platform on preceding back feeding chain.Different is: the height of the back feeding chain chain wing is greater than the material width; By bearing presser feet is installed on material reference platform top, front, presser feet bottom is a cambered surface, and the bottom surface is the plane, and the corresponding chain wing in presser feet bottom is provided with key way, the connecting rod that has adjustable for height light barrier, both sides to have end to rotate around stationary shaft in the middle of the presser feet top; There is the up stop screw of presser feet corresponding presser feet front portion, and there are descending stop screw of presser feet and extension spring in the rear portion; Photoelectric sensor is installed in the top of light barrier by support.

The utility model provide the ice cream sticks detection and selection machine, be provided with in (same as the prior art) width detection mechanism, thickness detection mechanism and the vertical curved machines a kind of, two or three, also be provided with above-mentioned the utility model ice cream sticks lateral bending testing agency simultaneously.

For helping blowing material, ice cream sticks lateral bending testing agency can be located at the rear portion of detection and selection machine, the preceding back feeding chain that is positioned at this lateral bending testing agency back is bent downwardly, and purge valve that should lateral bending testing agency is positioned on this bending section.

The detection principle of the utility model ice cream sticks lateral bending testing agency is, detected material before standing on the back feeding chain chain wing is when reference platform advances to the presser feet bottom surface, do not exist lateral bending or lateral bending not to be above standard as material, will pass through smoothly along the presser feet bottom surface, inoperative to presser feet, presser feet is failure to actuate, and the light barrier on its top can not produce sensor light and stop that material is regarded as certified products output; When the material lateral bending was above standard, the presser feet bottom surface can by lateral bending or the upper side edge that exceeds makes progress jack-up and presser feet is raise, and the light barrier on presser feet top also increases, and stops light, and photoelectric sensor then sends material and detects defective signal.

The utility model adopts material to pass through the presser feet indirectly-acting in the way of sensor light, has thoroughly overcome the above-mentioned shortcoming of prior art.During debugging, earlier the distance between presser feet and the reference platform is adjusted to standard value, adjust the height of presser feet top light barrier then, make it and the accuracy of detection that requires adapts by the descending stop screw at presser feet rear portion.Because light barrier is very near apart from photoelectric sensor the two poles of the earth, the signal reflection is sensitive, makes debugging simple, and quick, accuracy of detection also can be heightened.Because the chain wing of clamping material exceeds the upper side edge of material, and material is stood steadily, the phenomenon of selecting the chain wing greatly reduces, and the shutdown number of times during machine run also reduces naturally, and work efficiency can be guaranteed.During machine run, the reference platform even the material that has bottom does not recline, reference platform can recline under the pressure of presser feet when entering the presser feet bottom surface; Even the material side has tiny burr, also can be overwhelmed by presser feet, the two all can not cause the machine flase drop, and the false drop rate of machine dwindles greatly.
