[

3 is an illustration of a baggage loading schedule performed by the controller according to an embodiment of the present invention.

3A, when there is a specific cart passing through the first linear section 111 of the track 110 while the baggage 310 is moving from one of the at least one input section 120, The control unit can calculate the primary entry schedule for the baggage 310. [

In one embodiment, the control unit corresponds to a loading cart with no in-cart luggage among the plurality of carts on the track 110 and, based on the position of the loading cart and the position of the baggage 310, It is possible to perform synchronization only with respect to a loading cart located in a section where synchronization is possible. That is, the control unit can calculate the primary incoming schedule to check whether the mobile is in the loading cart in the synchronizable area.

Referring to Figure 3a, the position of the first loading cart 321 is located the most, and a slow position (D _l), the second loading cart 322 can be synchronized with the luggage 310 on the tracks 110 of the track (D _s ) that can be synchronized with the baggage 310 in the bag 110. That is, if the specific loading cart is located between the position of the first loading cart 321 and the position of the second loading cart 322, the baggage 310 can be received through the control of the synchronization area 220.

In one embodiment, the control unit can calculate the second incoming schedule, and since the position of the actual baggage may occur with the first incoming schedule due to an error corresponding to the jamming or jamming of the baggage with respect to the first incoming schedule, The incoming schedule can be confirmed again through the secondary incoming schedule. Referring to Figure 3b, it was the position of the hydrate change compared to Figure 3a, the position of the first loading cart 321 in accordance with a change in the position of luggage (D _l) and a second position of the loading cart (322) (D _s) It can also be adjusted.

In one embodiment, the control unit can identify the position of the loading cart that can draw in the baggage through the primary entry schedule and the secondary entry schedule, and consider the movement delay or delay of the baggage that may occur depending on the movement status of the baggage. And it is possible to calculate and confirm the secondary entry schedule after a predetermined time after the calculation of the primary entry schedule.

In one embodiment, if the control unit can not specify a loading cart to which to load the baggage at the primary entry schedule, i.e., the position of the slowest loading cart that can be synchronized in the track 110 and the position of the fastest loading cart It is possible to designate the loading cart at the time of calculation of the second incoming schedule after waiting for a predetermined time of the baggage. Here, during standby for a period of time, the hydrate may be stationary at the input, or may move the input at a predetermined speed (e.g., slower than during normal travel).

4 is an illustration of synchronization of an input unit performed by a control unit according to an embodiment of the present invention.

4, when the hydrate 310 reaches the synchronization area 220 through the transfer area 230 of the input part 120, the control part controls the hydrate 310 to move to the loading cart of the track 110 Synchronization can be performed by controlling the speed of the synchronization area 220 so that the synchronization can be achieved.

In one embodiment, when the controller 310 arrives at the point 410 where the baggage 310 enters the synchronization zone 220 through the delivery area 230 of the input 120, the control moves until the baggage reaches the track The speed at which the synchronization region 220 should be controlled can be calculated based on the distance to be supplied and the speed at which the hydrate is delivered in the delivery region 230 of the input portion 120 (i.e., the initial hydrate movement speed). More specifically, the moving speed of the baggage moving through the synchronization area 220 can be calculated through the following equation (1).

[Equation 1]

C _a = S _n2 * T _a + (S _{x -} S _n2 ) * T _a * 1/2 + (T - T _a ) * S _x

However, S _imin <= S _x <= S _imax

Sx = (2C _{a -} S _n2 * T _a ) / (2T - T _a )

If T _a -> 0, S _x = C _a / T

S _n1 : Speed at which the loading cart moves on the track

S _n2 : the rate at which the hydrate is delivered in the delivery region

T: Time taken by the loading cart to travel on section A (A / S _n )

C: Distance traveled by baggage until it reaches the track

T _a : the time it takes for the luggage to shift from S _n to S _x

S _x : speed at which the luggage of the input portion shifts in order to enter the track

C _a : C - current distance traveled (center of baggage) (ie, travel distance remaining)

More specifically, in Formula 1, a method of calculating C _a , that is, a distance that a hydrate has to travel, may be changed depending on the distance traveled while the moving speed of the hydrate is shifted, The distance traveled and the distance traveled by the shifted luggage during the time required for the luggage cart to move to the point where the luggage cart is moved after the luggage has been shifted.

In one embodiment, the control unit can determine whether the baggage 310 is moving at a normal speed through the speed sensor 420. [ If the moving speed of the baggage 310 detected through the speed sensor 420 is different from the speed controlled through the equation (1), synchronization can be performed again through the equation (1).

FIG. 5 is a diagram illustrating an example of calculating a bias measurement amount performed by the control unit according to an embodiment of the present invention.

5, when the hydrate 310 reaches the synchronization area 220 through the transfer area 230 of the input part 120, the control part determines that the hydrate 310 is in the loading cart of the track 110 It is possible to adjust the pull-in timing based on the left-right deviation measured amount of the hydrate 310 so as to be correctly drawn.

In one embodiment, the controller may measure the length and lateral deflection of the baggage 310 through the area sensor 510, which may be located between the delivery area 230 and the synchronization area 220. The length of the hydrate 310 is determined by the length of time from the start of the sensation of the hydrate 510 passing through the area sensor 510 to the moment of detection of the hydrate 310 and the time from the delivery region 230 to the synchronization region 220, Can be measured based on the speed of movement (i.e., length = time * speed).

In one embodiment, the lateral bias of the hydrate 310 can be measured by comparing the position where the sensor is sensed farther away from the center of the center of the area sensor 510. That is, the left-right degree of inclination of the hydrate 310 can be measured based on whether the hydrate 310 is biased in the B direction or biased in the C direction through the area sensor 510.

In one embodiment, the control unit may calculate the correction distance based on the amount of deviation of the hydrate 310, and based on the correction distance, when the baggage 310 is introduced into the loading cart, Can be adjusted. More specifically, the control unit calculates the time point of entry of the baggage 310 into the loading cart, so that the center point of the baggage 310 can be aligned with the center of the loading cart, based on the correction distance calculated through the following equation (2) Can be adjusted.

[Equation 2]

Correction distance = offset measurement amount / cos (contact angle between input part and track)

For example, when the correction distance corresponds to +10, the control unit determines that the loading cart reaches the point where the center of the loading cart coincides with the center line of the loading unit, and then the loading cart is moved by a distance corresponding to +10 The crossbelt cart of the loading cart may be driven to allow the baggage 310 to enter the loading cart.

For example, if the weight group corresponds to {weight range} {0 to 5 kg}, Group 2: {6 to 10 kg}, Group 3: {11 to 15 kg} and Group 4: {More than 16 kg}.

The control unit determines the track travel speed based on the determined weight group (step S602). In one embodiment, the track travel speed may be preset for each of at least one of the weight groups, for example, if the weight group is {weight range, track travel speed} 5kg and 1.2m / s}, Group 2: {6-10kg, 1.5m / s}, Group 3: {11-15kg, 1.7m / s} and Group 4: {16kg ~, 2m / s} .

The control unit operates the track based on the determined track running speed (step S603).

In one embodiment, the track running speed can be determined based on the weight of the baggage measured through the weighing area of the at least one input during travel of the track. In one embodiment, the weighing region may be located between the delivery region 230 and the synchronization region 220 of the input portion, and when there is no hydration in the synchronization region 220 of the input portion, The user can proceed to another bag through the delivery area 230 when the loading cart is to be loaded.

The presence or absence of hydrants in the cart is checked for a plurality of carts passing through the SPS area through the SPS area in the first linear line 111 of the track 110 (step S604). In one embodiment, if there is a hydrate in the cart, the presence or absence of hydration in the cart can be confirmed with respect to the other cart passing through the SPS area (step S605).

In one embodiment, when there is no hydration in the cart, a particular input may be selected for the cart to enter the hydrate (step S606). Here, the cart without the hydrate in the cart may correspond to a cart which can receive the hydrate from the input portion of one of the at least one input portion 120 as a loading cart.

In one embodiment, there must be only one loading cart to be loaded with the specific baggage in a particular input, and the control may store the loading cart in which the baggage is to be loaded, in relation to the specific baggage in the particular input, in association with the corresponding baggage . In addition, the control unit can prevent the luggage of the same input unit from being associated with the plurality of loading carts.

The control unit controls the running speed of the synchronization area 220 of the loading unit based on the position of the loading cart and the luggage to be introduced into the loading cart (step S607). In one embodiment, the control unit can control the time of entry of the baggage into the loading cart based on the speed of travel of the area of synchronization 220 and the amount of deviation of the baggage, so that the baggage can be correctly pulled into the loading cart .
