Then, the control means 15 causes the transfer mechanism 13 to perform a load distribution operation to the corresponding transport box 16 in the division storage unit 12 based on the identification information read by the reading unit 23 (still distribution). The rules will be described later).

The compartmentalized storage unit 12 has a plurality of transport boxes 16 that can move along the other directions (b1-b2) intersecting the transport direction of the transport unit 11, and is transported from the transport unit 11 to one of these transport boxes 16. The stored luggage N is stored.
These transport boxes 16 have various widths corresponding to the size of the cargo N and are located so as to be adjacent to each other, and each opening is arranged so as to face the transfer device 13. ing.

The transfer mechanism 13 is located between the end portion of the transport portion 11 and the division storage portion 12, and the standby plate 17 located on the upstream side and the transfer plate 18 located on the downstream side are formed. , Are adjacently arranged along the luggage transport direction (arrows a1-a2 direction).
The standby plate 17 is provided to allow the luggage N to be sent to the transfer plate 18 to stand by. Specifically, the standby plate 17 supplies, discharges, or discharges the luggage N to the luggage support plate 30 that supports the luggage N in an inclined state on the surface of the standby plate 17 and the luggage support plate 30. It has a bottom belt 31, a side belt 32, a holding roller 33, and a drive mechanism 34 for driving these belts and rollers.

The bottom belt 31 is located below the luggage support plate 30 and is arranged so as to be inclined at a predetermined angle with respect to the horizontal plane.
The side belt 32 is provided in a positional relationship perpendicular to the bottom belt 31, and is arranged on the luggage support plate 30.

The presser roller 33 is provided so that its peripheral surface can be displaced in the direction of advancing and retreating from the side belt 32, and makes it possible to sandwich luggage N of various sizes between the presser roller 33 and the side belt 32.
The presser roller 33 used in the present embodiment is configured so that the peripheral surface in contact with the load N is elastically deformed inward in the radial direction, and the elastic deformation between the presser roller 33 and the side belt 32. It is possible to insert various sizes of luggage N into the gap by making the gap size variable.
Specifically, the presser roller 33 is formed of a soft deformable elastic member such as a sponge, urethane foam, or rubber, has a substantially disk-shaped contour shape, and can rotate about the central axis 33a. Is. The presser roller 33 forms notches in a substantially arc shape at predetermined intervals in the circumferential direction around the central shaft 33a, thereby connecting the circular outer peripheral surface 33b with the holding portion of the outer peripheral surface 33b and the central shaft 33a. It has an arc-shaped spoke portion 33c.
The spoke portion 33c is formed so as to be curved rearward in the rotational direction from the central axis 33a toward the outer peripheral surface 33b. As described above, since the presser roller 33 is made of a sponge or the like having an elastic deforming force and has a notch, the presser roller 33 can be easily elastically deformed, and therefore the presser foot pressure of the load by the presser roller 33 becomes smaller. It is difficult to cause damage such as folding or crushing luggage N.

Then, in the standby plate 17 as described above, the bottom surface of the luggage N supported by the luggage support plate 30 contacts the bottom belt 31, the side surface of the luggage N contacts the side belt 32, and the side belt 32 and the side belt 32. The luggage N is sandwiched between the presser roller 33 and the presser roller 33. In this state, the bottom belt 31 and the side belt 32 are appropriately driven so that the luggage N supplied from the transport unit 11 is supported by the standby plate 17, and the luggage N on the standby plate 17 is divided. It is discharged to the storage unit 12.

The transfer plate 18 performs a synchronous operation in which the moving direction (b1-b2) of the transport box 16 and the moving speed thereof are the same, and the load is conveyed from the standby plate 17 via the transfer plate 18. N is distributed to one of the transport boxes 16 in the compartmentalized storage unit 12 via the luggage support plate 40 (described later).

The transfer plate 18 has a guide rail 19A that movably supports the luggage support plate 40 in the directions of arrows b1-b2 and a drive that moves the luggage support plate 40 along the guide rail 19A, as shown in FIG. A drive unit 19 having a drive mechanism 19C or the like for driving the belt 19B and the drive belt 19B is provided. For the guide rails 19A and 19B, for example, linear guides using rollers, balls, or the like are used.

Further, the transfer plate 18 is provided with a luggage support plate 40 that supports the luggage N in an inclined vertical posture on the transfer plate 18, and the luggage N is supplied, discharged, or sandwiched to the luggage support plate 40. A bottom belt 41, a side belt 42, a presser roller 43, and a drive mechanism 44 for driving these belts and rollers are provided.
The bottom belt 41 is located below the luggage support plate 40 and is arranged so as to be inclined at a predetermined angle with respect to the horizontal plane.
The side belt 42 is provided in a positional relationship perpendicular to the bottom belt 41, and is arranged on the luggage support plate 40.

The presser roller 43 is provided so as to be displaceable in the direction of advancing and retreating from the side belt 42, and makes it possible to sandwich luggage N of various sizes between the pressing roller 43 and the side belt 42.
The presser roller 43 used in the present embodiment is provided so that the peripheral surface in contact with the load N is elastically deformed inward in the radial direction, like the presser roller 33, and the side surface is elastically deformed by this elastic deformation. The size of the gap between the belt and the belt 42 can be made variable so that luggage N of various sizes can be sandwiched in the gap. That is, the presser roller 43 connects the circular outer peripheral surface 43b, the outer peripheral surface 43b, and the holding portion of the central shaft 43a by forming substantially arc-shaped notches in the circumferential direction around the central shaft 43a at predetermined intervals. It has an arc-shaped spoke portion 43c, and can be deformed following the outer shape of the luggage N while elastically deforming the outer peripheral surface 43b and the spoke portion 43c.

Then, in the transfer plate 18 as described above, the bottom surface of the luggage N supported by the luggage support plate 40 contacts the bottom belt 41, the side surface of the luggage N contacts the side belt 42, and the side belt 42 and the side belt 42. The luggage N is sandwiched between the presser roller 43 and the presser roller 43. At this time, the outer peripheral surface 43b and the spoke portion 43c can be elastically deformed according to the thickness of the luggage N to follow the outer shape of the luggage N.
That is, by appropriately driving the bottom belt 41, the side belt 42, and the presser roller 43, the luggage N is supplied from the standby plate 17 to the transfer plate 18, and the luggage N on the transfer plate 18 is supplied. Is sent out to the compartmentalized storage unit 12.
The side belt 42 and the bottom belt 41 constitute a first guide means and a second guide means, respectively.

The monitoring means 14 monitors whether or not the baggage N is stored in the predetermined transport box 16 depending on whether or not the detection light is blocked by the baggage N, and for example, a photoelectric sensor or the like is used.
The monitoring means 14 detects whether or not all the luggage N is contained in the compartmentalized storage unit 12, and the compartmentalized storage unit 12 is within a range in which the transfer plate 18 can be moved by setting the detection area. It is also possible to detect whether or not a part of the luggage N has popped out from the inside.
Here, the determination criterion in the monitoring means 14 is that even if the cargo N is not completely contained in the transport box 16, the amount of the cargo N protruding from the transport box 16 is small, and it collides with peripheral equipment or the like during subsequent transfer. If the amount of protrusion is so small that it does not occur, it is considered to be contained.

The control means 15 controls the drive of the transport unit 11, the standby plate 17 of the transfer mechanism 13, and the transfer plate 18 based on the identification information read by the reading unit 23 and the monitoring result of the monitoring unit 14. Therefore, it is also possible to retry the sorting operation of the luggage N by the transfer plate 18.

Next, the transport control program of the control means 15 will be described for each step S with reference to the operation diagrams of FIGS. 4 to 12 and the flowchart of FIG.
[Step S1]
By driving the bottom belt 31, the side belt 32, the presser roller 33 of the standby plate 17, and the bottom belt 41, the side belt 42, and the presser roller 43 of the transfer plate 18, the luggage N on the standby plate 17 is removed. Move it onto the transfer plate 18 (see FIGS. 4-6).
FIG. 6 shows the “initial position” after the luggage N on the standby plate 17 has moved onto the transfer plate 18, and in this “initial position”, the luggage N is placed on the luggage support plate 40 of the transfer plate 18. Is placed.

[Step S2]
Based on the identification information read by the reading unit 23, the drive mechanism 19C of the transfer plate 18 is driven to load the luggage N onto the luggage support plate 40, and the moving direction and the moving speed of the transport box 16 as the loading location. It is moved in the direction of arrow b1 in synchronization with (see FIGS. 6 and 7).

[Step S3]
By driving the bottom belt 41, the side belt 42, and the presser roller 43 of the transfer plate 18 in the forward direction in accordance with the movement of the load support plate 40 in the direction of the arrow b1 in step S2, the load support of the transfer plate 18 is supported. The luggage N on the plate 40 is moved in the direction of arrow a1 (see FIGS. 7 to 9).
As a result, the luggage N on the luggage support plate 40 of the transfer plate 18 can be guided into the corresponding transport box 16.

[Step S4]
At the same time as the processing of step S3 is started, the detection signal output from the monitoring means 14 is taken in, and the blocking status of the photoelectric sensor by the cargo N moving from the transfer plate 18 to the transport box 16 is monitored.

[Step S5]
It is determined whether or not the cutoff time of the sensor light measured in step S4 exceeds the preset time, and if NO, it is assumed that the luggage N has been normally stored in the transport box 16 and the present flowchart is terminated. Then, the transfer plate 18 is returned to the upstream side in order to feed the next baggage N. If YES, the process proceeds to the next step S6, assuming that there is a problem in storing the luggage in the transport box 16. The determination in step S5 is made before the transfer plate 18 is moved to 1/2 of the total movement stroke in the b1-b2 direction in anticipation of the time required to execute step S6 and some margin time. Is it completed?

[Step S6]
While continuing the synchronous drive of the drive belt 19B of the transfer plate 18, the bottom belt 41, the side belt 42, and the presser roller 43 are reversely driven, and the load N on the load support plate 40 of the transfer plate 18 is indicated by the arrow a2. Move in the direction and pull out from the transport box 16. Here, the return operation for retry is started on condition that the luggage N returns to the transfer plate 18 and the monitoring means 14 determines that the luggage N does not exist. That is, the transfer plate 18 is moved in the direction of the arrow b2, and then the process returns to step S1 to retry the feeding of the luggage N.
That is, as shown in FIGS. 9 to 12, the baggage N is returned to the "initial position" shown in FIG. 12, and then returns to the previous step S2, and the baggage N is stored in the predetermined transport box 16 again. Perform retry processing.
When the bottom belt 41, the side belt 42, and the presser roller 43 of the transfer plate 18 are reversely driven in order to return the luggage N determined to be abnormal, the speed is set to be higher than that when the luggage N is carried in. Even when the timing of the determination in step S5 is later (for example, than 1/2 of the total movement stroke in the b1-b2 direction), it is possible to take out the luggage N for retry.

As described in detail above, according to the transfer device 101 of the present embodiment, the load N conveyed in one direction (a1) by the transfer unit 11 is delivered to the transfer plate 18 of the transfer mechanism 13. After that, the transfer plate 18 moves in synchronization with the moving direction of the transport box 16 and the moving speed thereof, and moves along the other direction (b1-b2) which is the moving direction of the transport box 16.
As a result, the luggage N on the transfer plate 18 is guided to the predetermined transport box 16, and whether or not it is stored in the transport box 16 is monitored by the monitoring means 14.
Further, the control means 15 of the present embodiment can control the drive of the transfer plate 18 of the transfer mechanism 13 based on the monitoring result of the monitoring means 14.

As a result, in the transport device 101 of the present embodiment, for example, based on the monitoring result of the monitoring means 14, it is detected that the luggage N on the transfer plate 18 of the transfer mechanism 13 is not stored in the predetermined transport box 16. In this case, it is possible to return the baggage N to the initial position before sorting and retry the sorting process.
As a result, in the transport device 101 of the present invention, when the luggage N is not completely transferred into the transport box 16 and is in a state of straddling between the transfer mechanism 13 and the transport box 16, the luggage N is sorted. Since it can be returned to the previous initial position, it is possible to avoid damage to the transfer mechanism 13, the transport box 16, or the luggage N.

In the transport device 101 of the embodiment, the retry processing of steps S1 to S5 through step S6 is performed a preset number of times, and even if the retry processing for the set number of times is executed, the load is delivered to the predetermined transport box 16. When the storage cannot be performed, the entire transport device 101 may be stopped and a warning signal may be output to the operator.

Further, as the monitoring means 14, a photoelectric sensor was used to detect the state of luggage storage in the transport box 16 depending on whether or not the detection light was blocked at the entrance of the transport box 16.
However, the present invention is not limited to this, and as a monitoring means 14, a contact sensor that opens and closes a contact by a micro switch and a pin that can be moved by a spring is provided at the entrance of the transport box 16, so that the load N to the transport box 16 is N. You may monitor the storage status of the.
In the embodiment, the upstream portion of the transfer plate 18, that is, the bottom belt 31, the side belt 32, and the holding roller 33 do not move synchronously, and only the bottom belt 41, the side belt 42, and the holding roller 43 on the downstream side do not move synchronously. Although it is configured to move synchronously, the range to which the transport mechanism for sending the load N to the transport box 16 may be synchronously moved may be appropriately changed according to the distribution method of the load N and the layout of the present device. Of course.

Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment and includes design changes and the like within a range not deviating from the gist of the present invention.
