[0017]
A plurality of bread loaf groups 11 coming from the bread slicer are carried into the containers 14, 15, 16 from the loading position I, and each bread group 11 is directed to the packaging machine from the section 20 of the containers 14, 15, 16 As shown in FIG. 1, the unloading position O to be unloaded is set corresponding to each of the orthogonal straight portions of the guide member 13 in which the containers 14, 15, 16 (section 20) move linearly. Then, by rotating the arms 24, 25, 26 independently by the servo motors 32, 33, 34, the bread pans for the respective sections 20 in a state where the containers 14, 15, 16 are stopped at the loading position I. When the group 11 is carried in from the outside and the center of each compartment 20 of the containers 14, 15, 16 is moved to a position corresponding to the center of the carry-out position O and stopped, the bread from the compartment 20 is stopped. The group 11 is unloaded from the inside. Accordingly, the front and rear of the bread loaf group 11 when being carried into the containers 14, 15, 16 at the carry-in position I and the front and rear of the bread loaf group 11 being carried out from the containers 14, 15, 16 at the carry-out position O are Vice versa. For example, in the case of a mountain-shaped bread, the bread group 11 carried into the containers 14, 15, 16 with the round head side in front at the carry-in position I is carried out after leaving the head at the carry-out position O. It is like that.
[0018]
When the size of the section 20 set in each container 14, 15, 16 is changed when changing the order, the number of pulses for controlling the rotation of each servo motor 32, 33, 34 is changed. By performing the above, it is configured to be able to move and stop so that the center of each changed section 20 corresponds to the center of the carry-out position O.

[Operation of the first embodiment]
Next, the operation of the article transport apparatus according to the first embodiment will be described. An example in which four compartments 20 having the same size are formed between the supports 18 and 18 in each of the containers 14, 15, and 16 will be described.
[0020]
For example, in the case of a mountain-shaped bread, the bread of 3 mm length is fed to the bread slicer with the round head side in front, and the slicer is sliced into pieces that can be divided into four. . The obtained slice bread group is divided into a predetermined number of bread bread groups 11 and fed into the article conveying apparatus 10 in a parallel state with the round head side in front. In this article transporting apparatus 10, as shown in FIG. 1, the first container 14 is stopped at the carry-in position I, and each bread group 11 fed from the bread slicer corresponds to the partition member 19. It is carried into each of the four compartments 20 from the side at a time. At this time, each bread group 11 is pushed over each section 20 from the outside of the track in a direction substantially perpendicular to the straight track portions of the containers 14, 15, 16 and is brought into the carry-in state.
[0021]
In the article transporting apparatus 10, by rotating the first servo motor 32 corresponding to the first container 14 by a predetermined amount, the first container 14 moves from the carry-in position I toward the carry-out position O. It moves on the guide member 13. In addition, since each bread group 11 is accommodated in each section 20 defined by the partition member 19, the movement of the first container 14 is not displaced in the moving direction. Further, by rotating the second servo motor 33 corresponding to the second container 15 by a predetermined amount, the second container 15 is stopped corresponding to the loading position I. Further, by rotating the third servo motor 34 corresponding to the third container 16 by a predetermined amount, the third container 16 stops on the near side of the loading position I where it does not contact the second container 15. Is done.
[0022]
When the center of the section 20 at the forefront in the moving direction of the first container 14 arrives at a position corresponding to the center of the unloading position O and stops, unloading means (not shown) contains bread loaves housed in the corresponding section 20. The bread loaf group 11 is carried out toward the packaging machine by abutting on the side 11. At this time, each bread group 11 is pushed out of the track in a direction substantially orthogonal to the straight track portion of the containers 14, 15, 16 (section 20). When the bread bread group 11 of the foremost section 20 is carried out, the first servo motor 32 is driven, the first container 14 moves downstream (moving direction), and the adjacent succeeding in the container 14 When the center of the section 20 arrives at a position corresponding to the center of the carry-out position O, the first servomotor 32 is stopped, and another bread group 11 is carried out by the carry-out means as described above. By carrying out the above operation four times, the carry-out of the bread loaf group 11 from all the sections 20 of the first container 14 is completed. In this example, one bread group 11 is a packaging unit, and the carry-out operation of each bread group 11 is performed in correspondence with the packaging timing of the packaging machine.
[0023]
While the bread bread group 11 is being carried out from the first container 14, the bread bread group 11 is carried into the second container 15 facing the loading position I and the second servo. By rotating the motor 33 by a predetermined amount, the second container 15 is moved from the carry-in position I toward the carry-out position O. Further, by rotating the third servo motor 34 by a predetermined amount, the third container 16 arrives at the carry-in position I, and the bread bread group 11 can be carried into the container 16.
[0024]
And when the bread bread group 11 is carried out from all the divisions 20 of the 1st container 14, the center of the frontmost division 20 in the subsequent 2nd container 15 corresponds to the center of the carrying-out position O. The second servomotor 33 is rotationally controlled so as to move up to. While the bread bread group 11 is being carried out from the second container 15, the bread bread group 11 is carried into the third container 16 facing the carry-in position I, and the third servo is moved. The third container 16 is moved from the carry-in position I toward the carry-out position O by rotating the motor 34 by a predetermined amount. Further, by rotating the first servo motor 32 by a predetermined amount, the first container 14 arrives at the carry-in position I, and the bread bread group 11 can be carried into the container 14.
[0025]
That is, the arm 24, 25, 26 is independently rotated by the three servo motors 32, 33, 34 to move and stop the containers 14, 15, 16 so as to correspond to the loading position I. And the operation | movement which moves and stops the division 20 in the accommodating body 14,15,16 different from it corresponding to the conveyance position O can be performed independently. Accordingly, for example, the containers 14, 15, 16 are moved and stopped for each section at the carry-out position O to carry out the bread loaf group 11, while another container 14, 15 different from that at the carry-in position I is stopped. , 16 can be loaded with a plurality of bread groups 11 divided into four, and high-speed processing can be achieved.
[0026]
Further, in the article conveying apparatus 10 of the first embodiment, the guide member 13 to which the containers 14, 15, 16 move does not move in the horizontal direction. The carry-in position I or the carry-out position O can be set in (Part). That is, the article carry-in position I and the article carry-out position O can be provided so that the carry-in direction and the carry-out direction are linearly overlapped or orthogonal to each other, and the packaging machine connected to the carry-out position O can be provided. The degree of freedom of arrangement (layout) increases, and the effective use of space in the factory can be achieved. Moreover, since the guide member 13 does not move, the device itself can be made compact. Furthermore, since the centers of rotation of all the arms 24, 25, and 26 are set concentrically inside the guide member 13, the apparatus can be further downsized.

When the bread loaf group 11 in the foremost section 20 of the first container 14 is carried out, the first servo motor 59 is driven, and the first toothed belt 71 is moved. Thereby, the first container 14 linearly moves downstream (moving direction), and when the center of the adjacent subsequent section 20 in the container 14 arrives at a position corresponding to the center of the unloading position O, The first servo motor 59 is stopped, and another bread group 11 is carried out by the carrying-out means as described above. By carrying out the above operation three times, the carry-out of the bread loaf group 11 from all the sections 20 of the first container 14 is completed. Moreover, the carrying-out operation | movement of each bread group 11 is performed corresponding to the packaging timing of the said bagging machine (packing machine).
[0036]
In addition, when carrying out the operation of carrying out the bread loaf group 11 from the first container 14, the loading of the bread loaf group 11 into each section 20 of the second container 15 facing the carry-in position I is completed, When the second servomotor 60 is driven and the second toothed belt 72 is moved, the second container 15 facing the carry-in position I is moved downstream. The amount of movement at this time is set to a value that does not interfere with the first container 14 located on the downstream side. When the bread bread group 11 is unloaded from all the sections 20 of the first container 14, the center of the foremost section 20 in the subsequent second container 15 reaches a position corresponding to the center of the unloading position O. The second servomotor 60 is rotationally controlled so as to move. In addition, while the bread bread group 11 is being carried out from the second container 15, the bread bread group 11 is carried into each section 20 of the third container 16 facing the carry-in position I. By rotating the third servo motor 61 by a predetermined amount, the third container 16 is moved from the carry-in position I toward the carry-out position O. Further, by rotating the first servo motor 59 by a predetermined amount, the first container 14 arrives at the carry-in position I, and the bread bread group 11 can be carried into the container 14.
[0037]
That is, also in the second embodiment, the toothed belts 71, 72, 73 are independently rotated by the three servo motors 59, 60, 61, so that the containers 14, 15, 16 are brought into the loading position I. The operation of moving and stopping so as to correspond to each other, and the operation of moving and stopping the compartment 20 in another container 14, 15, 16 so as to correspond to the carry-out position O can be performed independently. Therefore, a plurality of breads divided into three at the carry-in position I while carrying out the bread bread group 11 by moving / stopping the first to third containers 14, 15, 16 by one section at the carry-out position O, for example. The group 11 can be carried into another container 14, 15, 16 other than that which is stopped, and high-speed processing can be achieved.
[0038]
Further, when the two unloading positions O and O are set as in the second embodiment, for example, the two unloading positions O and O are loaded while loading the bread 11 into the first container 14 at the loading position I, for example. By stopping the second container 15 and the third container 16 independently at O, the bread loaf group 11 can be carried out to the bag filling machine and the horizontal bag making and filling machine. In addition, even when the bag filling machine and the horizontal bag making and filling machine are arranged side by side, the guide member 52 does not move in the horizontal direction, so that the length of the apparatus can be suppressed. Furthermore, since the three accommodating bodies 14, 15, and 16 are disposed in the toothed belts 71, 72, and 73, the conveyance processing capacity of the bread group 11 is improved.
[0039]
In this case, after the bread bread group 11 of one section 20 defined in one container 14, 15, 16 is carried out to the horizontal bag making and filling machine at the carry-out position O on the upstream side, the same container 14, 15 is used. , 16 can also be carried out to the bagging machine at the carry-out position O on the downstream side. That is, the plurality of bread loave groups 11 accommodated in one container 14, 15, 16 can be distributed to the two carry-out positions O, O and carried out. Further, the bread bread group 11 may be carried out only toward the packaging machine installed corresponding to the upstream delivery position O. In this case, the same kind of packaging machine is installed corresponding to the two delivery positions O, O. However, when a problem or the like occurs in the upstream packaging machine, the loss time can be reduced by carrying the bread loaf group 11 to the downstream packaging machine for backup.
