Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a device for loading a stacking container in which a plurality of parts manufactured by a press, for example, poly cases, which are stacked, are stacked on a palette.

[Prior Art] Conventionally, in the case of stacking containers in which articles are respectively stored and stacked on a pallet, there are various proposals as disclosed in, for example, Japanese Patent Publication No. 47-16938. However, since these stacked containers having a rectangular planar shape are arranged in the same direction and arranged on the pallet, it is easy for the load to slip. On the other hand, when stacking stacked containers by sequentially changing the direction by 90 degrees onto a square-shaped pallet, the load will not be lost, but it must be done by a robot in order to carry out automatically. Therefore, there is a problem that a space for installing the robot is required and the cost is high.

[Problems to be Solved by the Invention] The present invention solves such a point and can be installed in a small space for automatically stacking stacked containers on a pallet so as not to collapse, and is simple and inexpensive. The present invention provides a stacking device for stacking stacked containers as described above.

[Means for Solving the Problems] The present invention supports a pallet for supporting a pallet, a drive device for rotating the pedestal by 90 degrees and stopping it, and a stacking container. Stacking container pallet, characterized by including an extruder for pushing out onto the pallet when the support table is stopped and a control device for automatically controlling the rotation of the support table and the operation of the extrusion apparatus. To provide a loading device for the vehicle.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

In the embodiment of the present invention shown in FIGS. 1 to 5, reference numeral 10 denotes a stacking apparatus for stacking stacked containers as a whole. 12 is a square support for supporting the pallet 13.
Reference numeral 15 is a base that rotatably supports the support base by an annular protrusion 16 formed on the upper surface, and 17 is a control device. 1
Reference numeral 8 is a motor which serves as a drive device, and is adapted to rotate a shaft 23 extending downward from the support base 12 through the chain 20 and the sprocket 21 by 90 degrees in response to a signal from the control device 17. Reference numeral 25 is a sensor for detecting the stop position of the support 12, and reference numeral 26 is a projection on the lower surface of each corner of the support 12, two projections outwardly protruding so as to slightly open. Reference numeral 27 denotes an engagement member that moves forward and backward between the protrusions 26 by an air cylinder 28 in response to a signal from the control device 17, and holds the support base 12 at a predetermined position when engaged between the protrusions 26. In addition to such engaging means, it is needless to say that other engaging means for preventing the support base 12 from rotating with respect to the base 15 may be used.

Reference numeral 30 denotes a table, which supports a stacked container 90 formed by stacking containers 91 each containing an article. The stacking container 90 is, for example, sent from another supporting means 31 via the roller conveyor 32. Reference numeral 33 denotes a movable table which is retracted from the state shown in FIG. 1 by the air cylinder 35 so that the support 12 and the pallet 13 can be rotated, and is returned again. The movable table 33 is disposed between the support 12 and the table 30. There is. The movable table may be movable to another portion, for example, moved to the lower side of the table 30. A pusher 36 is an pushing device which is operated by an air cylinder 37 provided on the table 30, and sends a stacking container 90 on the table 30 to the pallet 13 through a movable table 33 in response to a signal from the control device 17. It is becoming like this. In the state shown in FIG. 1, the support base 12 is rotated by 90 degrees for each delivery, and the loading is completed by delivering four times. When the loading is completed, the pallet 13 is properly transported by a not shown forklift. By stacking the stacking containers 90 on the pallet 13 in this manner, the cargo can be prevented from being collapsed and can be transported. In this embodiment, as shown in FIG. 6, the stacking container 90 having a narrow width may be stacked twice on the pallet 13 four times in succession.

In another embodiment of the present invention shown in FIGS. 7 and 8, a stacking device for loading the stacked containers on a known device 40 for storing articles in empty stacked containers and stacking them again. The case where 10 is connected is shown. In this figure, 41 is a conveyor for transferring empty stacking containers 90. Reference numeral 42 denotes a main body, which is adapted to be lifted by engaging the arm members 43 on both sides of the second and higher stages, leaving the container 91 at the lowermost end of the stacked container 90 transferred to a predetermined position by this conveyor. The remaining container 91 is a three-stage engaging portion 4 that engages only when it is transferred to the left side in the drawing.
Articles are supplied from a supply device 50 by being transferred to a lower portion of the main body part 42 by an engaging part 46 of a transfer device 45 composed of an air cylinder having 6, 47 and 48. During this time, the stacked container 90 lifted by the arm member 43 descends, and only one container 91 is left again to lift the others. In this state, the container 91 accommodating the articles and the empty container 91 are simultaneously transferred to the next stage by the operation of the transfer device 45. The container 91 accommodating the articles is transferred onto the table 51 which also serves as the table of the stacking device 10 by the engaging portion 47 and is lifted by the arm member 53 extending from the main body portion 42 so that another container 91 can come down. Then, the containers 91 are stacked, lifted and held. When the total number of the containers 91 held by the arm member 53 and the next container 91 reaches a predetermined number by repeating such an operation, the arm member 53 descends and the stacked container 9 containing the articles.
0 will be released. The stacking container 90 is pressed by the engaging portion 48, passes through the movable table 33, and is stacked on the pallet 13. The pallet 13 is rotated as described above, and the same operation is repeated. All of this is done automatically,
A known device 40 for accommodating articles in respective stacked empty containers and stacking them again is automatically loaded on the pallet 12 without stacking the stacked containers 90 coming out.

In this invention, for example, in the embodiment shown in FIG. 1 and the like, an air cylinder is used without rotating the motor 18 to rotate the support base 12, or an air cylinder 37 is used to operate the pusher 36. You may use.

[Advantages of the Invention] Since the present invention is configured as described above, the stacking container 90 can be automatically loaded on the pallet 12 with a simple and inexpensive structure and in a minimum space without being unbalanced. Has the effect.
