Abstract

The utility model discloses an edge searching regulating and controlling device which comprises a feeding frame, a power controlling group, an edge searching group, an edge searching sensor group and a manual or automatic switch; the feeding frame can move to the left and to the right and can be against by materials; the hand automatic switch is switched automatically or by hand; the edge searching sensor group comprises two sensors which are respectively connected with a controlling device; the sensor is an air pressure type edge searching sensor or an electric eye sensor; the power controlling group comprises the controlling device, a pressure unit and a stop valve; the controlling device controls the pressure unit and transmits pressure through the stop valve; the pressure pushes the feeding frame to move to the right or to the left; therefore, when moving away from the positioning area between the two sensors because of the migration, the edge of the materials triggers one of the two sensors, starts the controlling device, connects a linked pressure unit to transmit pressure and push the feeding frame and moves the edge of the material return to the positioning area.

Description

Seek the limit regulation device

Technical field

The utility model is about a kind of limit regulation device of seeking, especially refer to a kind of provide instant and stably mobile cradle seek the limit regulation device, can apace locating area be returned in the adjustment of out-of-position material, time difference is reduced, improve the accuracy of rolling material location on the cradle, reduce the skew that material cuts or prints.

Background technology

Automated machine equipment will be made production procedure systematization and mechanization, replace manual operation, not only improve prouctiveness greatly, relatively, the mistake that also reduces manual work and produced, after for example the cloth cutting operation is positioned the rolling material for guillotine, can draws apace and send and cut, cloth is positively cut apart according to required size; The making of plastic bag product is a cross bar of plastics prototype bag volume being located at cradle, be arranged in plastics envelope cutter inside again after, through back cover and cut off and promptly finish the plastic bag output.

In the above-mentioned operation process, be to guarantee that cloth or plastics prototype bag that rolling is to be cut keep the location in the feeding process most importantly, if establishing to draw,, machine vibration improper because of being provided with or volume move angular deflection, cause the left and right sides offset of material, to cause that to cut the edge inconsistent, the trimmed size error is big, forms waste material or is returned goods by the client, so need further with the edge trace operate unit material position to be adjusted and located.

Therefore also a kind of full vapour-pressure type edge trace operate unit is arranged, the edge trace operate unit of its exposure will detect the boundary position of object, and when the bits of offset of the generation left and right sides, the edge of machined object, automatic compensation returns back to fixed point at any time, to avoid cropped diversified in specifications of material.

The cradle of said structure is the axostylus axostyle push-and-pull that is subjected to air cylinder, left and right displacement with the control material, yet, the edge of vapour-pressure type induction material, or the air pressure transmission pressure all can postpone because of gas has height compressibility generation time to pass the mode of cradle, that is when the edge begun the skew, pass about beginning to cradle to reply the overlong time of position, under the situation of mechanical fast turn-around and feeding, the deviation that cuts has made that waste material produces in a large number.

Edge this, the experience that the designer of this case accumulation manufactures and designs for many years through constantly thinking deeply, make and revising, has birth of the present utility model, then to address the above problem.

The utility model content

The technical problems to be solved in the utility model is: a kind of limit regulation device of seeking is provided, and it does an immediate reaction with Null oil-pressure equipment with the tracking at material edge, solves the shortcoming of full vapour-pressure type control.

Another technical matters to be solved in the utility model is: a kind of limit regulation device of seeking is provided, its have the hand automatic transfer switch for the hand adjustment cradle about the skew.

Technical solution of the present utility model is: a kind of limit regulation device of seeking, and it comprises:

One cradle, but its left and right displacement and feed spare are against the ground setting;

One power control group, it comprises first controller, second controller, first pressure unit, second pressure unit, first non-return valve and second non-return valve, first controller links first pressure unit and first non-return valve in regular turn, this first non-return valve is linked to cradle, and this first controller and second non-return valve link, second controller links second pressure unit and second non-return valve in regular turn, and this second controller and first non-return valve link;

One seeks the limit sense group, and it comprises the first sensor and second sensor, and the first sensor and first controller link, and second sensor and second controller link;

One manual control group, it comprises first direction control knob and second direction control knob, and the first direction control knob and first controller link, and the second direction control knob and second controller link; And

Automatic transfer switch on the other hand, its with seek limit sense group and manual control group and link;

Thus, the hand automatic transfer switch switches under the auto state, when the locating area of the edge of materials and parts between between the first sensor and second sensor, first controller and the second not start of controller, when the edge of materials and parts leaves this locating area because of skew, to trigger the first sensor or second sensor and drive first controller or second controller, then interlock first pressure unit or the second pressure unit delivery pressure make the edge of materials and parts be reset to this locating area to pass cradle.

As from the foregoing, advantage of the present utility model is:

1. the utility model adopts the Null oil-pressure mode, makes the sensor signal immediate reaction make the cradle left and right displacement to the oil pressure power plant, the shortcoming of improving existing full vapour-pressure type induction and moving.

2. the utlity model has the hand automatic transfer switch, be available for users to conveniently carry out the fine setting of cradle, help the adjustment at materials and parts edge, in order to the processing of processing equipment in switching automatically and manually.
