Abstract

PURPOSE:To dispense with a cargo pool area by providing a wheeled cage supporting device in such a way that the device can move to the right and left and up and down, making it possible to move this supporting device in the fore-and-aft direction relative to a loading device, and combining these movements in loading the cargo. CONSTITUTION:A cargo 3 on a carrying line 1 is shifted and mounted onto a wheeled cage 7, which is supported by a lifter 6, via a discharging roller device 2, a roller conveyor 4, and an expansion conveyor 5. By expanding or contracting a carrying belt sideways, the expansion conveyor 5 moves the falling spot of the cargo 3 to the forward or backward (or in the direction in which the cages are lined up). By the aide of the lifter 6, the wheeled cage 7 makes ascending/descending motion (in the direction of H) and lateral movements (in the direction of J), thereby adjusting the falling spot of the cargo 3 in the wheeled cage 7. With this constitution, by suitably combining the ascending/ descending motion and lateral movements of the wheeled cage 7 and the forward/backward movements of the expansion conveyor 5, the cargo 3 can be loaded successively and methodically into the wheeled cage 7. With this contrivance, a cargo pool area can be dispensed with.

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to automatic cage car loading equipment for loading (loading) cargo transferred from a conveyance line onto a cage car in multiple stages.

Conventional technology As a device for loading conventional cargo into multiple stages, the
A pallet loading device is disclosed in Japanese Patent No. 49451. This pallet loading device pools a predetermined number of loads that are sequentially brought in by a carry-in conveyor, and when the predetermined number of loads is reached, it is pushed onto an alignment plate.When the loads are aligned in multiple rows on the alignment plate, they are transferred to the pallet via a carriage. The pallet is configured to be pushed upward to transfer the pallet, lower the height of the pallet, and perform the next transfer.

Problems to be Solved by the Invention However, conventional loading devices require an area to pool the loads brought in, and therefore require a large installation space. The present invention solves the above problem, and aims to provide automatic loading equipment for carts that can be loaded sequentially without requiring a pooling area for imported cargo. Means for Solving the Problems In order to solve the above-mentioned problems, the cage car automatic loading equipment of the present invention includes a loading device that transfers the load transferred from the conveyance line to the cage car, and a loading device that transfers the cargo transferred from the conveyance line to the cage car, and a loading device that moves the cage car in the vertical and horizontal directions. The loading device and the cage support device are configured to be movable relative to each other in the front and rear directions, and the cage support device is configured to move vertically and horizontally, and the loading device and the cage support device are movable relative to each other in the front and rear directions. The device is equipped with a control device that controls the relative movement of the device in the front-back direction, changes the position where loads are transferred from the loading device to the cage truck, and sequentially stores the loads.

Furthermore, a second invention provides the loading device of the first invention, in which the telescopic belt is expanded and contracted in response to a control signal from a control device to change the transfer position to the cage truck in the front and back direction, so that the loading device is not transferred from the conveyance line. It consists of a telescoping belt conveyor that transfers the incoming cargo to a cage truck. Further, a third invention provides the cage car support device of the first invention,
This allows the cage car to move forward and backward. Effect With the configuration of the first invention described above, the control device controls the vertical and horizontal movement of the cage car support device and the relative movement in the front and rear direction of the loading device and the cage car support device to transfer the load from the loading device to the cage car. Then, the cargo is stored in the cart one by one, and then the cargo is loaded onto the cart. Further, according to the configuration of the second invention, by using a telescopic belt conveyor as the loading device, the relative movement of the loading device and the car support device in the front and rear direction is performed by expanding and contracting the telescopic belt. Further, according to the configuration of the third invention, the relative movement of the loading device and the cage car support device in the front-rear direction is performed by moving the cage car in the front-rear direction by the cage car support device.

EXAMPLE Hereinafter, an example of the present invention will be explained based on the drawings. FIG. 1 is a perspective view of an automatic car loading facility showing an example of the present invention. Loads 3 branched from a conveyance line 1 by a roller device 2 for discharging are transferred via a roller conveyor 4 to a loading device. The cargo is transferred from a telescopic belt conveyor 5 to a cage car 7 supported by a cage lifter 6, which is a cage support device.

As shown in FIG.
In the gap between A and IB, there is a plurality of drive rollers 8 (five in the drawing) that can be raised and lowered and whose directions can be changed, and when the load 3 passes, the drive rollers 8 are connected to the belt conveyor IA.
It is located on the same plane as the top surface and faces the conveyance direction M. When the load 3 is to be delivered, the drive roller 8 is driven so as to protrude from the top surface of the belt conveyor IA, and is directed toward the roller conveyor 4, facing the conveyance direction M. The conveyed load 3 is conveyed toward the roller conveyor 4 as shown by the imaginary line. Further, as shown in FIGS. 3A to 3C, the telescopic belt conveyor 5 includes a belt 1 stretched between a fixed roller 9 and a movable roller 11 supported diagonally by a pair of springs 10.
2 is passed through a pair of fixed rollers 13 and 14 provided at an intermediate rear position of the belt 12, and a movable roller 15 that is movable in the vertical direction indicated by the arrow H in response to a control signal, and the movable roller 15 is moved vertically. By moving the belt 12, the belt 12 is expanded and contracted in the diagonal direction shown by the arrow K, and the dropping position of the load 3 can be moved in the front-rear direction shown by the arrow K. Further, the cage car lifter 6 is connected to the cage car 7 as shown in FIG.
The cage car 7 is shaped like an ellipse so that it can be moved in the horizontal direction indicated by the arrow J and in the vertical direction indicated by the marking H. When the lifter surface 6A on which the cage car 7 is placed is at the same level as the floor surface, the cage car 7 moves in the direction shown by the arrow G. The car moves forward in the forward direction shown by , and the cage car 7 that was in the rear direction is placed on the lifter surface 6A.

This movement of the cage car 7 is performed by a forced movement device (not shown). Further, the lifter 6A is provided with a holding device for holding the cage car 7 in a fixed position. A control device 16 controls the movement of the belt 12 of the telescopic belt conveyor 5 in the front-back direction shown by the arrow K, the movement of the lifter 6A of the cage car lifter 6 in the vertical direction (not shown by the arrow H), and the left-right direction shown by the arrow J.
By controlling this, it is possible to load the cargo 3 onto the cage car 7 in an orderly manner so that the cargo does not fall apart.

As shown in FIG. 4, the control device 16 is connected by a cable to a sorting controller 17 that controls the telescopic belt conveyor 5, the car lifter 6, and the dispensing roller device 2. As shown in FIG. 1, the sorting controller 17 receives a barcode signal of the sorting destination read from a label provided on the load 3 from a barcode reader 18 provided along the conveyance line 1 on the upstream side of the dispensing roller device 2. Enter
The dispensing roller device 2 corresponding to the sorting destination is driven, and at the same time, the same drive signal is output to the control device 16 of the cage car automatic loading equipment from which the cargo 3 is discharged by the dispensing roller device 2 for this purpose. Also, the sorting controller 17
When an abnormality signal is input from the control device 16 to the automatic car loading equipment, the system locks the drive of the unloading roller device 2 that unloads the load 3 to this equipment, thereby preventing the load 3 from being unloaded. The operation of the control device 16 will be explained according to the flowchart in FIG. As shown in Fig. 5, the basket car 7 is loaded with a total of 16 loads 3, with 4 items per tier and 4 tiers. First, check whether a device abnormality signal is input from the telescopic belt conveyor 5 or the cage car lifter 6! (step F-1), and if an abnormal signal is input, it is set to the sorting controller 17 (ii) and outputs an abnormal signal (step F-1).
-2), if no abnormal signal is input, check whether a drive signal is input from the sorting controller 17 (Step F-3>. If this drive signal is not input, terminate the process and input If so, after a certain period of time T1 has elapsed (steps F-4 to F-6), the value N of the counter that counts the loading of loads 3 becomes the number K (=16 (step F-7), and if N=K, send a position command signal to the cage car lifter 6 to bring the cage car 7 to the same level as the floor, that is, to move the cage car 7 forward. A replacement command signal for placing the next cage car 7 on the lifter surface 6A is output (step F-8), and after the elapse of time T2 at which the replacement of the cage car 7 is completed (steps F9 to F-11>, the value of the cage Reset N (
Step Fi2>. The above-mentioned time T1 is the maximum time until the load 3 discharged by the roller device 2 for dispensing is stored in the basket car 7. After the elapse of this time T1, the load 3 is placed in the basket car 7 in preparation for storing the next load 3. The cars 7 are replaced, or the positions of the telescopic belt conveyor 5 and car lifter 6 shown in the next step are changed.

In the case of N:l:K in step F-7, or after the end of step F-12, the counter value N is incremented by 1 (step F-13), and according to the value of N,
For example, as shown in Table 1, a drive signal indicating a predetermined movement position is output to the telescopic belt conveyor 5 and the cage lifter 6, and the telescopic belt conveyor 5 is moved so that the load 3 falls to the storage position of the next load 3. Move the belt 12 and the cage car 7 (
Step F-14). When the control device 16 outputs the drive signals shown in Table 1 according to the counter value N, the loads 3 are loaded into the two forward stages in the order of numbers from ■ to [phase] shown in FIG. Load 3 is loaded on the first stage in the rear direction, cargo 3 is loaded on the first stage in the front direction, cargo 3 is loaded on the first stage in the rear direction, and cargo 3 is loaded in the first stage in the forward direction. Loaded, and finally 2 in the rear direction
Load 3 is loaded onto the stage. By performing loading with priority given to the forward direction, the cargo 3 is prevented from collapsing and transferred. When loading is completed, the cage truck 7 is moved.

Table 1 In this way, by moving the belt 12 of the telescopic belt conveyor 5 in the front-back direction and moving the lifter surface 6A of the cage car lifter 6 in the vertical and horizontal directions, the load 3 is transferred to the cage car 7. By changing the loading position, there is no need to pool the load 3 onto the roller conveyor 4, and by loading the load with priority in the forward direction, the load 3 can be collapsed even if the size of the load 3 is slightly different. Therefore, the loads 3 can be stored in order and in an orderly manner.

Although not shown in the drawings, branching sections using discharging roller devices 2 are installed at multiple locations on the conveyance line 1, and automatic cage loading equipment is installed at each branching section.
Therefore, while the cargo 3 is being sorted, it can be sequentially transferred to the basket cars 7 for each sorting destination. In addition, in this embodiment, the telescopic belt conveyor 5 of the loading device is
The loading device and the car support device are moved relative to each other in the front and rear direction by moving the belt 12 of the car support device in the front and back direction. By making it movable in the front and rear directions, it is also possible to perform relative movement of the loading device and the car support device in the front and rear directions.

Furthermore, it goes without saying that by changing the movement position indicated by the drive signal in accordance with the value N of the counter in Table 1, the order of the positions at which the cargo 3 is loaded onto the cage car 7 can be changed. Furthermore, it is possible to install an ITV that can take pictures of the inside of the cage car 7 on the telescopic belt conveyor 5, monitor the height of the cargo 3 stored in the cage car 7 using the ITV, and load the cargo with priority given to the front direction. It is. It is also possible to load the cargo 3 onto the cage truck 7 by directly transferring the cargo 3 to the automatic cage loading facility without providing a branching section.

Effects of the Invention As described above, according to the present invention, by changing the position where the load is transferred from the loading device to the cage car and storing the load in the cage car in the third stage, the load can be transferred to the cage car in an orderly manner. Furthermore, it does not require a pooling area on the conveyor line, so it can be installed even in a small installation space.

Further, according to the second invention, the relative movement in the front-rear direction between the loading device and the cage car support device can be realized by the expansion and contraction of the elastic belt of the telescoping belt conveyor, and according to the third invention, the relative movement can be realized by the cage car support device. This can be achieved by moving the cage car back and forth using a device.
