Abstract

PURPOSE:To shorten the regulation time by calculating the distance between a load detecting device and an expelling device by the line moving rate and the pulse signal number of a pulse encoder within a standard time, and setting the motion timing based on the obtained result. CONSTITUTION:The shoot judging means 13 of an assortment controller 11 determines the assorting shoot by the assortment data signal l from a host computer 8 and the detection signal j from a detecting device 7, and outputs selection signals P1-P3 to counter means 14a-14f directly or through switches 15a, 15b. The pulse signal n of a pulse encoder 12 is inputted to each counter means 14a-14f and a counter setting means 20. The counter setting means 20 determines each set point B1-B3 of the counter means 14a-14f from the distance and transfer speed between the detecting device 7 and expelling devices 3a-3c. The counter means 14a-14f controls the timing of each expelling devices 3a-3c by this set point. This constitution enables the shortening of the regulation time.

The present invention solves the above problem, and aims to provide a method for adjusting the operation timing of a dispensing device in a sorting facility that does not require time to adjust the operating timing of the dispensing device.

Means for Solving the Problems In order to solve the above problems, the present invention provides a plurality of chutes arranged along the side of a conveyance line for conveying loads, and a plurality of chutes corresponding to the entrances of these chutes. a dispensing device disposed on the line and sorting by discharging loads from the line to a chute by operation; a load detecting device disposed in the line upstream of the chute; detecting the conveyance speed of the line; A pulse encoder outputs a continuous pulse signal corresponding to the conveyance speed, and a load detection signal from the load detection device is used to count the number of pulse signals of the pulse encoder corresponding to the distance from the load detection device to the dispensing device. control means for operating the payout device, the control means measures the number of pulse signals of the pulse encoder input within a reference time, and determines the operation timing of each payout device by controlling the load detection device. The distance between the line and each dispensing device is calculated and set using the moving speed of the line and the number of pulse signals obtained by measurement.

Since this is done automatically, there is no need to adjust the operation timing, and the time required to adjust the sorting equipment is reduced. Further, conventionally, the operation timing was determined by visual sense, but by setting it by calculation, the operation timing of each dispensing device becomes the same timing.

EXAMPLE An example of the present invention will be described below based on the drawings. It should be noted that the same components as those of the conventional example shown in FIG.

FIG. 1 is a block diagram of a sorting controller that implements the method of adjusting the operation timing of a dispensing device in a sorting facility according to the present invention. The sorting controller 11, which is this control means, uses a data signal for sorting the loads 4 sent from the upper host computer 8, a load detection signal j for the loads 4 from the load detection device 7, and a load detection signal j for the load 4 from the load detection device 7, as shown in FIG. As shown, belt conveyors 18 to 1d are arranged along belt conveyor 1b.
A continuous pulse signal n corresponding to the conveyance speed of the belt conveyors 1a to 1d from the pulse encoder 12 that detects the conveyance speed of the belt conveyors 1a to 1d is input, and the dispensing roller devices 3a, -3 are inputted.
It outputs the drive signal kllk21 that drives the signals b and 3c.

In FIG. 1, 13 is a sorting chute 2a.

2b and 2c, and for sorting the load 4, it sequentially compares the data signal rising and the load detection signal j of the load 4 to determine the chute 2a, 2b, 2c for sorting the load 4, and determines the chute 2a, 2b, 2c for sorting the load 4. Counter means 14a-14f, which is the driving means for the roller group [3a, 3b, 3c, directly or by a switch 15a.

Selection signals Pp, , p, are outputted via the terminal 15b.

The switches 15a and 15b are configured so that their positions change sequentially each time the selection signals P, , P, are output. The counter means 14a to 14f each receive a selection signal P0°P2. P,
R-S flip-flop 1G whose set input is R
- AND circuit 1 that takes the logical product of the output signal of the S flip-flop 16 and the pulse signal n from the pulse encoder 12

First, the number of pulse signals n input during 10 sac is counted. Assuming that the number of pulses counted during 10 seconds is 2, the time per pulse y (n+sac/
pulse) becomes. In addition, belt conveyor a to 1d 1m5ac
The amount of movement a (W*5ec) per pulse is, and the amount of movement β (+a
