Abstract

The utility model relates to an easy slitting box with sheet picking mechanisms, which comprises a beam, a ball screw, a linear guild rail, a slitting box mechanism and the sheet picking mechanisms, wherein the slitting box mechanism is fixed in a suitable position of the beam, the four sheet picking mechanisms are respectively and uniformly mounted on the beam, the slitting box mechanism comprises a slitting box shaft and sheet guide rails, and each sheet picking mechanism comprises a lower support, straight pins, a pull pin frame, springs and conical pull pins; the beam is mounted on the ball screw and the linear guild rail, and a step motor is connected with the ball screw and drives the beam to move horizontally. The utility model has the advantages that the slitting box is conveniently opened, an IP (intermediate positive) chip retreats, and the slitting box is automatically closed and locked so as to simplify the mechanism, widen the position accuracy of the slitting box and improve the reliability of the slitting box. The utility model changes a prior extrusion mode for closing the slitting box; after the IP chip is scanned, the step motor reverses the IP chip to retreat to the slitting box which is closed and locked by a slitting box locking mechanism, therefore, the service life of the slitting box is prolonged, and the IP chip is prevented from being scraped.

Description

A kind ofly simple and easyly hack box and hold sheet mechanism in the month

Technical field

This utility model relates to and a kind ofly simple and easyly hacks box and hold sheet mechanism in the month.

Background technology

In the CR system, hacking box and holding sheet mechanism in the month is by the structures shape of film magazine, external CR device hold that sheet mechanism has in the month realize holding in the month sheet, complex structure with compressed air absorption.Nineteen ninety-five, in the CR system of our research, hacking case structure is an ejector pin, when ejector pin inserts the film magazine top, opens the spring retaining mechanism, and spring discharges, and flicks film magazine, holds sheet mechanism in the month and is made up of compressed air mechanism, suction nozzle, actuator.Compressed air mechanism by inflator, tooth bar, motor, etc. form; Suction nozzle by: flexible pipe, sucker and support are formed; Actuator is made up of stepper, cam etc.; After film magazine was opened, gas rotated with motor, drives tooth bar inflator is pulled out, suction nozzle place air forms negative pressure, and under effects such as stepper, cam, suction nozzle moves to the IP front end, fall, absorption IP, the stepper counter-rotating is delivered to IP under the pressure roller, the counter-rotating of inflator motor, suction nozzle discharges, and finishes and holds sheet in the month, and the shortcoming of this mechanism is mechanism's complexity.2002, in the CR system of our design, film magazine was designed to double door, hacks the box mouth at the film magazine back side, hacks box and is finished by four electric magnet; Holding sheet in the month is to be finished by four intermediate plate mouths.When film magazine insertion CR reading device, film magazine is clamped, and the control electromagnetic actuation hacks the insertion of box ejector pin and hacks the box mouth, opens the spring retaining mechanism, and spring discharges, and flicks film magazine.The IP positive and negative exposes, four intermediate plate mouths arranged in a uniform, under the drive of stepper, move to the film magazine direction, vertical rod on the intermediate plate mouth collides horizontal iron clamp sheet mouth and opens, enter IP, the stepper counter-rotating is finished and is held the sheet action in the month, the shortcoming of this mechanism is a complex structure, required precision height, poor reliability, easily causes IP to scratch.

The utility model content

The purpose of this utility model provides a kind ofly simple and easyly hacks box and holds sheet mechanism in the month, overcoming the existing product complex structure, and required precision height, poor reliability, the deficiency that easily causes IP to scratch.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind ofly simple and easyly hack box and hold sheet mechanism in the month, comprise crossbeam, ball-screw, line slideway, hack case structure, hold sheet mechanism in the month, crossbeam is installed in and hacks the correct position that case structure is fixed on crossbeam on ball-screw and the line slideway; Hold sheet mechanism in the month for four and evenly be installed in respectively on the crossbeam, wherein hack case structure by hack the box axle, the slice, thin piece guide rail is formed, hold in the month sheet mechanism by lower carriage, sell directly to households, draw pin support body, spring, taper to draw pin to form; Crossbeam is installed on ball-screw and the line slideway; Stepper links ball-screw, drives the crossbeam horizontal movement.

The beneficial effects of the utility model are: open film magazine easily, reliably IP is held in the month out from film magazine, IP closes film magazine and locking after returning film magazine automatically; Four of past are hacked box electric magnet circle lean on ejector pin and change one into and hack the box axle, simplified mechanism, relaxed the positional precision of hacking box, improved the reliability of hacking box; Changed the mode of squash type pass film magazine in the past, after IP had scanned, stepper counter-rotating IP return film magazine, and film magazine is closed, and the film magazine retaining mechanism pins, and improves the film magazine life-span; Avoid the IP scratch.

Description of drawings

Fig. 1 is the described simple and easy structural representation that hacks box and hold sheet mechanism in the month of this utility model embodiment;

Fig. 2 is an A-A view among Fig. 1;

Fig. 3 is a B-B view among Fig. 1.

Among the figure:

1, line slideway; 2, ball-screw; 3, crossbeam; 4, hack case structure; 5, hold sheet mechanism 5 in the month; 6, sell directly to households; 7, draw the pin support body; 8, pin is drawn in taper; 9, lower carriage; 10, slice, thin piece guide rail; 11, hack the box axle; 12, spring.

The specific embodiment,

As Figure 1-3, this utility model embodiment is described simple and easyly to be hacked box and holds sheet mechanism in the month, comprise crossbeam 3, ball-screw 2, line slideway 1, hack case structure 4, hold sheet mechanism 5 in the month, crossbeam 3 is installed on ball-screw 2 and the line slideway 1, hacks case structure 4 and is fixed on the correct position of crossbeam 1 to guarantee to open the film magazine of four kinds of different sizes; Holding sheet mechanism 5 in the month for four evenly is installed in respectively on the crossbeam 1 to guarantee to hold in the month the IP sheet of last four kinds of different sizes, wherein hack case structure 4 by hack box axle 11, slice, thin piece guide rail 10 is formed, hold in the month sheet mechanism 5 by lower carriage 9, sell 6 directly to households, draw pin support body 7, spring 12, taper to draw pin 8 to form; Crossbeam 3 is installed on ball-screw 2 and the line slideway 1; Stepper links ball-screw 2, drives crossbeam 3 horizontal movements.

The IP film magazine is inserted the reading device of CR system, the action of control film magazine clamp mechanism, clamp film magazine, the control step machine rotates, driving crossbeam moves to the film magazine direction, hacking the box axle inserts and to hack the box mouth on the film magazine, open the spring retaining mechanism, spring discharges, and flicks the film magazine lock, when hacking box, a corresponding horizontal ferrum (not providing among the figure) is clashed in the direct selling of holding in the month in the sheet mechanism, the compression spring, pin-and-hole is drawn in the taper that the drive taper draws pin to raise and enter the preceding rib top of film magazine, and dilatory IP supporting plate is finished and is held action in the month.After IP has scanned, stepper counter-rotating IP returns film magazine, film magazine is closed, and the film magazine retaining mechanism pins, at the same time, the horizontal ferrum (not providing among the figure) of a correspondence is clashed in the direct selling of holding in the month in the sheet mechanism, the compression spring drives taper and draws pin to raise, the stepper counter-rotating, hack case structure and hold sheet mechanism disengaging film magazine in the month, finish everything.
