Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a bogie on which a box or the like filled with articles such as bolts and nuts can be automatically stacked on a bogie in a predetermined number of stages and in a predetermined row. It relates to a box stacking device.

(Prior Art) Boxes filled with bolts, nuts, etc. are delivered to a user's factory in a multi-tiered state on a trolley to save floor space. However, since such a case has a heavy weight per one, it is not easy to handle manually, and it is difficult to improve the efficiency of the stacking work. Therefore, the present applicant previously invented an apparatus for automatically stacking boxes supplied one by one from a box sending section up to a predetermined number of steps and sending them out on a conveyor, and proposed them as JP-A-60-128130. It was required to stack the boxes in a plurality of rows on the trolley, and at the conveyor end, it was necessary to transfer the boxes onto the trolley by a forklift or the like.

(Problems to be Solved by the Invention) The present invention solves the conventional problems as described above, and automatically stacks a box filled with articles in a predetermined number of stages on a trolley in a predetermined row. It has been completed to provide a box stacking device on a trolley capable of

(Means for Solving the Problems) The present invention made to solve the above problems provides a rail between a box sending-out section for sending out a box filled with articles and a bogie stop section apart from the box sending-out section. A gate-type carriage that is laid and can be stopped at multiple positions on the carriage set on the carriage stop section is installed freely on this rail, and the boxes sent from the box sending section are sequentially installed on this gate-type carriage. It is characterized in that a box lifting mechanism for hooking and stacking a predetermined number of steps is provided.

(Example) Hereinafter, the present invention will be described in more detail with reference to the illustrated example.

In the figure, (1) is a box sending part, (2) is a dolly stopping part located at a position slightly apart from this, (3) is a rail laid on the floor between them, and this rail ( 3) A gate type carriage (4) is movably installed on the top.

The box sending unit (1) includes an empty box magazine (5) that stores empty boxes B in a stacking state in multiple stages, and a swing plate (7) that is openable and closable by cylinders (6) on the left and right sides of the magazine. Is equipped with. The rocking plate (7) is a cylinder (6)
Although it supports the flange portion of the lowermost box B when it is closed via a link by means of the structure, only the lowermost box B can be dropped onto the table when opened as shown in the figure. . A cylinder (9) with a projecting piece (8) for box feeding is horizontally provided on the lower surface of this table, and the box B dropped from the empty box magazine (5) is directly below the packing chute (10). send. The boxing chute (10) can supply articles such as bolts supplied from a bolt manufacturing machine into the box B by a fixed amount.

The gate type carriage (4) travels on the rail (3) by the drive wheels (12) driven by the geared motor (11) and comes into close contact with the box delivery section (1) as shown in FIG. The position on the far side of the bogie (13) stopped at the bogie stop (2) shown in FIG. 2 and the bogie (13) shown in FIG.
It is possible to stop at three positions, the upper position on the front side. At each stop position, stoppers (14a), (14b), (14c) are provided on the side of the rail (3),
Further, a dog (15) which is moved up and down by a cylinder is provided on the gate type carriage (4) side, and an accurate stop position is secured by bringing the dog (15) into contact with a stopper. Further, a gate frame (16) is erected on the upper surface of the gate type carriage (4), and a box pulling mechanism (18) which is moved up and down by the upper and lower cylinders (17) is provided on both side surfaces thereof. As shown in FIG. 5, the box pulling up mechanism (18) has an L-shaped lower end that can rotate upward but cannot rotate downward from the horizontal position. It is equipped with a hook (19). This box pulling mechanism (18)
The box B is lifted by the hook (19) of FIG. 1 and the next box B is sent below the box B, and the hook (19) is lowered by the cylinder (17). Although it gets on the top, when the hook (19) is further lowered from this state, the hook (19) descends while escaping to the upper side as shown by the dotted line in FIG. 5, and lower than the flange of the lower box B. Moving. Then, when the hook (19) is raised by the cylinder (17), the hook (19) engages with the flange of the lower box B, and the box B stacked in two stages can be lifted. By repeating this operation a predetermined number of times, the box lifting mechanism (18)
Has a structure in which the boxes B can be stacked a predetermined number of times, and in the case of the embodiment, the boxes B can be stacked in nine steps.

Note that (20) is a clamp device, (21) is a guide rail for the truck (13), and (22) is a bolt for fixing the truck.

(Operation) In the apparatus of the present invention thus configured, first, as shown in FIG. 1, the gate type carriage (4) is moved to the box sending section (1) side and clamped by the clamp device (20), In this state, as described above, articles such as bolts are supplied from the packing chute (10) into the box B dropped from the lower end of the empty box magazine (5), and then the cylinder piece (1) is moved by the projecting piece (8). The boxes are sent one by one below the box lifting mechanism (18) of the gate type carriage (4). Then, the box raising mechanism (18) stacks the boxes B to a predetermined number of stages as described above.

Next, the gate type carriage (4) moves on the rail (3) onto the carriage (13) of the carriage stop (2) as shown in FIG.
At the position on the back side of 3), the box lifting mechanism (18) is lowered to place the stacked boxes B on the carriage (13). At this time the trolley (1
3) The trolley (1
3) is fixed in position. After that, the gate type carriage (4) returns to the position shown in Fig. 1 again to stack the boxes B in the same manner, and then the box B stacked at the front side position of the carriage (13) as shown in Fig. 3 is loaded. Put. In this way, the boxes B can be stacked in a plurality of rows on the carriage (13), and then the carriage (13) is
As shown in the figure, it is pulled out from the trolley stop (2).

The stop position of the gate type carriage (4) on the rail (3) is regulated by the stoppers (14a), (14b) and (14c) and the dog (15) which can be moved up and down to be brought into contact with the stoppers (14a), (14b) and (14c). It When the gate type carriage (4) moves beyond the stopper (14b), the dog (15) is pulled upward.

(Effects of the Invention) As described above, the present invention fully automatically stacks a large number of boxes, which are filled with articles, with a predetermined number of stages, and
It can be placed in multiple rows in front and back on the dolly,
It is possible to stack the boxes on the trolley efficiently without the need to manually move the boxes by a forklift or the like as in the conventional case. Therefore, the present invention, as a box stacking device on a trolley that eliminates the conventional problems, has an extremely great contribution to the industrial development.
