Abstract

A compacting feed device which is used for accurately pulling and feeding a workpiece material belt comprises a base, at least one motion platform glidingly matched with the base, at least one stationary platform fixed on the base, a first compacting device and a second compacting device respectively fixed on the motion platform and the stationary platform; wherein, the workpiece material belt is fixed in the first compacting device and the second compacting device. The compacting feed device of the utility model has two sets of compacting devices; wherein, the first compacting device is mounted on the motion platform; the second compacting device is installed on the stationary platform and keeps stationary. The whole compacting feed device is flexible in use, convenient in regulation and very convenient in adjustment of the workpiece material belt. The compact contact part can be made of soft materials without effect on feeding precision; moreover, the movement of the compacting device and the workpiece material belt directly adopts a vertical downward pressing relation instead of a rolling movement relation, so pieces are not easy to be damaged by pressing. The device is easy to make, thus correspondingly reducing design and production cost.

Description

Compress pay-off

[technical field]

The utility model relates to a kind of pay-off that compresses, the transmission control of the workpiece strip that refers to manufacturing equipment and conveyor line processed and applied especially in automation processing compress pay-off.

[background technology]

As Fig. 1, in the automation processing, usually needing processing originally is that the mono-processing work is intended in the course of processing, according to a certain specific rule, processing work is linked together in some way (perhaps on the strip raw material, process, and reservation links together), make up a long banded structure, it is workpiece strip 10, than being easier to realize full-automatic production, as carrying out leapfrog processing, a step is finished an operation like this, the n step has just been finished n operation, in the end they is separated in the operation again.

As shown in Figures 2 and 3, work schematic flow diagram for existing workpiece strip, as Fig. 1, the workpiece strip 10 that processes is in regular turn by preceding control 11, a plurality of operation processing stations 12, back control 13, preceding control 11, final operation processing stations 12, back control 13 and last rewinding or leftover bits operation 14, this a whole set of structure, the accurate leapfrog transmission that guarantees workpiece strip 10 reaches functions such as stablizing the workpiece combination of transmitted, these functions realize by preceding control 11 and back control 13, control 11 is take-up devices wherein, back control 13 is accurately to draw (sending) device, and accurately drawing (sending) device is that workpiece 10 is accurately delivered on each station.

For adopting the pay-off 13 of scroll wheel mode, there are the following problems for it as Fig. 4:

A) scroll wheel is designed to hard wheel, can weighs the workpiece strip wounded;

B) scroll wheel is designed to soft wheel, the diameter of wheel diminishes along with the increase of pressure, and promptly the diameter of wheel has uncertain problem.

In the prior art, feed distance with how many angles of wheel turns is controlled, the rotation radian that draws the distance of (sending) material to equal wheel is multiplied by the radius of wheel, in this relation, probabilistic result of the radius of wheel (diameter), can't accomplish accurately to draw " sending " material.

Therefore, be necessary to design a kind of new pay-off, make to compress that it doesn't matter with feed distance, to overcome above-mentioned defective.

[utility model content]

The technical matters that the utility model institute desire solves is to provide and compresses and loosen function, and the vertical compression contact compress pay-off.

The technical scheme that the utility model adopted provides a kind of pay-off that compresses, be used for accurately drawing and send the workpiece strip, comprise: a pedestal, be slidingly fitted at least one motion platform on this pedestal, be fixed at least one fixed platform on this pedestal, first pinch device that is separately fixed at this motion platform and fixed platform and second pinch device, wherein the workpiece strip is fixed in first pinch device and second pinch device.

The utility model compresses pay-off to have two covers and compresses device, i.e. first pinch device and second pinch device, first pinch device is installed on the motion platform, second pinch device is installed on the fixed platform, maintain static, the whole pay-off workflow that compresses is: the first pinch device workpiece pressing strip---first pinch device drives the workpiece strip and travels forward---behind the relevant position, first pinch device stops---the second pinch device workpiece pressing strip---and first pinch device unclamps the workpiece strip---first pinch device returns original position---repetitive cycling said process originally compresses pay-off and has following advantage:

1. technology is reliable: only need can compress the conveying work pieces strip by the compressing and loosen the workpiece strip of first, second pinch device;

2. use flexibly, easy to adjust, it is also very convenient to adjust the workpiece strip: by adjusting motion platform itself just can adjusting motion apart from, speed and acceleration/accel;

3. the contact portion that compresses can be used the soft material manufacturing, can not influence pushing precision, and pinch device and the workpiece strip vertical relation of depressing of direct employing of moving, and does not have the rolling movement relation, is not easy to produce the part problem that weighs wounded;

4. make easily: the structure of motion platform, fixed platform and pinch device is very simple, has reduced design and productive costs accordingly.

[specific embodiment]

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

See also Fig. 5 to Fig. 7, compress the structural representation of pay-off for utility model, originally compress pay-off 100 and be used for manufacturing equipment and conveyor line processed and applied field, refer in particular to the transmission control of workpiece strip 20 in automation processing, guaranteeing that the accurate leapfrog transmission of workpiece strip and stabilizer elements combination pass function such as establishes, wherein workpiece strip 20 is formed by a plurality of workpiece 21 with the strip 22 that will these a plurality of stations links together, and strip 22 is positioned at the both sides of these a plurality of workpiece 21.
