Body is installed, since this dispenser mounting surface is higher relative to the perpendicular or parallel degree of input, output shaft, equipment Installation base surface, which has to guarantee, makes input, output direction of principal axis and the input needed for equipment, outbound course of this dispenser coaxial.No Can deflection or bias.Otherwise, output accuracy is not only influenced, and can seriously damage dispenser.Because at this moment, dispenser In abnormal stress.It is body scheme of installation such as Fig. 5：

I. the dispenser is to cut extension set cutter structure for 1 point 5. through high accuracy obtained from Precision Machining and correct equipment adjustment. User is before use, must not without authorization adjust, dismantle, assemble.

Ii. confirm that the dispenser mounting surface has not damaged, if any damage, repaired with oilstone.

Iii. centering input, the position of output shaft, fill positioning pin, equably tighten screw.

Iv. the dispenser bears pulsating load moment loading, and installation must be very firm.

Input shaft is installed, in the combination of Cam splitter and motor, driving flowing mode that motor is connected with input shaft Have：Pulley drive, chain gear transmission, synchronous belt pulley transmission, gear drive, shaft coupling transmission etc..During operation, due to The pulsation of load, camshaft torque had positive and negative change in one week, can cause the skidding of transmission device, so, camshaft Rotating unstability can be impacted to the torque added by dispenser, so as to be unable to reach our required precision.Therefore, No matter technically, or using empirically, the belt that cannot be all slided on camshaft and motor drive with producing is used as The medium of transmission, but use can produce the chain of pulsation and the gear for having gap drives.To ensure at the same time the belt that uses or Chain stretching.The present embodiment uses synchronous belt pulley transmission.Because the advantages of synchronous belt and synchronizing wheel is more, one is can ensure It is synchronous；In addition, synchronous belt will not produce gap with synchronizing wheel in transmission process；And smaller, Neng Goushi is vibrated in use Now run at high speed；At the same time in order to strengthen stability, select the synchronizing wheel effect of major diameter better.Carrying out gear or synchronization During the selection of wheel, it is ensured that the precision used, back lash will be removed with synchronous belt or chain collocation.

Output shaft is installed, and the present embodiment is linked together output shaft and chassis using ring flange, passes through flange dish driving Chassis rotates.Together with ring flange is screwed between chassis.It is quiet by moving to due to turntable by static to movement Only, inertia force is big.Along with the fit clearance of connector, often it is easy to produce loosening between output terminal and connector.Make Preshoot or hysteresis into output driving member, produce vibration.Output accuracy is so not only reduced, and can seriously destroy segmentation Device and its cam and needle bearing of inside.

Therefore, should be noted during installation：

I. hole, axis fit clearance cannot be excessive, and key connection cannot be too loose.

Ii. axis is docked with axis, between flange connection cannot eccentric or deflection, to ensure concentricity.

Iii. flanged joint filling pin, blending bolt are tightened.

Ii. manually just or despining worm shaft is so that telescoping tube reaches suitable position, the length of setting, which does not exceed, to be pushed away The limiting value of bar

It is intact, clean whether the part for iii. examining installation fixed is processed, and ensures these parts with to be installed on push rod The sizes of parts coincide.

Iv. ensure that electric pushrod only by axial load, such as occurs fastening or is subject to non axial load, electric pushrod cannot Normal work.

(2) inspection that direction substitutes

Motor is started, checks whether the explanation on the traffic direction and switch board of inner tube is consistent, if inconsistent, stops at once Electric-examination is looked into

(3) maximal work position is checked

Check whether the dimension limit of electric pushrod is consistent with the extreme position for the workpiece to be moved

(4) trial operation

One working cycles of electric pushrod are run under no-load condition, gradually increase load running working cycles until reaching most Heavy load.

Six, go out fore-edge detection device

After books are pushed out out fore-edge, wait is removed.Go out fore-edge and sensor is housed, after books are removed, machine Original state is automatically restored to, waits sale next time.Going out fore-edge detection device can use photoelectric sensor and pressure sensor real Existing, concrete structure is as shown in Figure 10：

1. pressure sensor is realized

(1) brief introduction type selecting

Pressure sensor is a kind of sensor the most commonly used in industrial practice, is a kind of that pressure conversion is defeated for electric signal Electric measuring type instrument in pressure measuring instruments, is usually called pressure sensor by the sensor gone out.The present embodiment final purpose is Realize that customer asks for bought books nationality, therefore book is detected to going out the pressure change of fore-edge by pressure sensor, so as to judge exactly Whether books are removed, and conveniently realize related procedure.With reference to the characteristics of the present embodiment, related sensitivity, precision, stability, line The requirement of property scope etc. is not high, it is therefore intended that realizes qualitative analysis.Therefore the present embodiment uses resistance-strain pressure sensor.

(2) operation principle

Resistance strain gage is pasted onto in flexible member particular surface, when things such as power, moment of torsion, speed, acceleration and flows When reason amount acts on flexible member, the change of element stress and strain can be caused, and then cause the change of resistance-strain sheet resistance. The change of resistance being exported in a manner of electric signal after processing of circuit, so as to fulfill the detection to pressure change, further Determine whether fore-edge books are removed.

2. photoelectric sensor is realized

(1) brief introduction type selecting

Photoelectric sensor is the principle of reflection near infrared ray light beam using object, is reflected by synchronization loop sensing Light, the presence or absence of detection object is carried out according to its power, and photoelectric sensor sends infrared light beam and reaches or through object first Body, object or minute surface reflect infrared light beam, and photoelectric sensor receives the light beam reflected, according to the power of light beam The presence of judgment object.

For the present embodiment by considering, selection uses correlation optoelectronic switch.It is by separated transmitter and reception Device forms.When have no occluder, receiver receives the infrared ray that transmitter is sent, the action of its contact；When there is object to block, Receiver does not just receive infrared ray, its contact resets.

(2) install

I. during erecting and welding, the pin root of photoelectric sensor and the minimum range of pad cannot be less than 5mm, otherwise weld When fragile tube core.Or cause the change of tube core performance.Weld interval should be less than 4 seconds.

Ii. the front end face of photoelectric sensor and detected workpiece or the necessary keeping parallelism of body surface in use, so The transfer efficiency highest of photoelectric sensor.

Iii. correlation photoelectric sensor minimum detectable width is the 80% of this kind of optoelectronic switch lens width.

The above, is only the preferable embodiment of the invention, but the protection domain of the invention is not This is confined to, any one skilled in the art is in the technical scope that the invention discloses, according to the present invention The technical solution of creation and its inventive concept are subject to equivalent substitution or change, should all cover the invention protection domain it It is interior.
