 The present invention relates to an automatic feeding device for a self-propelled vehicle of a carriage that is connected to the self-propelled vehicle.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, in assembly factories and warehouses, there is an unmanned vehicle in which an unmanned vehicle is connected to a trolley along a pre-defined traveling path by a guide tape laid on the floor. In order to connect an empty carriage (a carriage with no articles loaded) to the self-propelled vehicle, the empty carriage is manually placed and placed at a predetermined position on the traveling path of the self-propelled vehicle. There is.

[0003]

[Problems to be solved by the device]

 Therefore, there was a problem that man-hours were required to convey the empty truck to the position where it was connected to the self-propelled vehicle. In order to eliminate such inconveniences, there is disclosed an automatic feeder for a carriage that automatically conveys an empty carriage to a connecting position with respect to a self-propelled vehicle, but this automatic feeder is a large-scale and complicated device. Therefore, there were defects that were difficult to implement. Therefore, an object of the present invention is to make it possible to automatically supply an empty vehicle to a position where it is connected to a self-propelled vehicle with a simple device.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, an automatic feeder for a transporting trolley according to the present invention is provided with a pair of left and right guide plates that guide the left and right sides of the trolley and are vertically fixed to the floor, and fixed to the floor inside the guide plates. The front and rear cylinders that reciprocate back and forth, the upper and lower cylinders that are fixed to the movable side of the front and rear cylinders and move vertically, and the pins provided on the bottom of the bogie when the upper and lower cylinders are raised. It is characterized by comprising a hook to be engaged. It is desirable that the front and rear cylinders and the upper and lower cylinders are electrically connected to each other, and that the upper and lower cylinders are provided in the front-rear direction of the front and rear cylinders at regular intervals.

[0005]

[Action]

 When the dolly is manually inserted into the left and right guide plates, the upper and lower cylinders actuate and the hook rises to the position where the dolly pins are engaged, and then the front and rear cylinders actuate to move forward and the upper and lower cylinders move. Move forward along with the hook. Along with this movement, the hook engages with the pin, transports the carriage forward together with the pin, and after transporting it to a predetermined position, the upper and lower cylinders actuate to lower the hook, and the front and rear cylinders retract to return to the original position. Then, the next carriage is ready to be transported.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show the device of the present invention, in which (10) and (11) are a pair of left and right guides fixed to the floor (F) in an upright manner with a slightly wide interval with respect to the left and right width of the carriage (T). The trolley (T) is fed in the direction of the arrow into the left and right guide plates (10) and (11) by the plate, and the left and right side surfaces of the trolley (T) are guided as shown in FIG.

The front and rear cylinders (2) are arranged on the floor (F) between the left and right guide plates (10) and (11) along the guide plates (10) and (11). Is composed of a fixed rail (21) fixed to the floor (F) and a movable rail (22) fitted to the fixed rail (21) and movable in the front-rear direction by hydraulic pressure or an air cylinder (24). A plurality of rails (22) are arranged in the front-rear direction (in the figure, three upper and lower cylinders (3) are fixed via mounting plates (23)).

As shown in FIG. 2, the upper and lower cylinders (3) are hydraulic and air cylinders, the cylinders (31) of which are fixed to the mounting plate (23) and the rods (32) are provided in the vertical direction. The hooks (30), (30 ') and (30 ") are fixed to the tip of the rod (32). The hooks (30) engage with the pins (40) of the truck (T). The hooks (30) are arranged so as to be positioned in the center between the left and right guide plates (10) and (11). The front and rear cylinders (3) are cut into a V shape so as to engage with the front and rear cylinders (2) at substantially the same intervals as the entire length of the carriage (T). ).

At the ends of the guide plates (10) and (11), the upright plates (10A) (11A) are fixed in an expanding manner, and the upright plates (10A) (11A) are used to confirm the empty carriage. Sensor (4) is installed. The floor (F) between the upright plates (10A) and (11A) is provided with a truck positioning cylinder (5) with a vertically movable stopper (51).

The front and rear cylinders (2), the upper and lower cylinders (3), and the truck positioning cylinder (5) are electrically connected to each other. That is, when there is no carriage above the upper and lower cylinders (3) on the side of the carriage positioning cylinder (5), the empty carriage confirmation sensor (4) detects it and the upper and lower cylinders (3) (3) ′) (3 ″) operates to raise the hooks (30), (30 ′) and (30 ″), and at the same time, the stopper (51) of the truck positioning cylinder (5) also rises, and then the front and rear cylinders (5). 2) is moved forward, the carriage (T) is conveyed and hits the stopper (51) of the carriage positioning cylinder (5), the hooks (30) of the upper and lower cylinders (3) ... 2) is configured to retreat. In FIG. 2, reference numeral (41) in the figure denotes wheels of the carriage (T).

3 and 4, the hook (30) is engaged with the pin (40) provided on the bottom surface of the carriage (T), and the carriage (2) inside the guide plates (10) and (11) is moved by the front and rear cylinders (2). In the figure, (42) is a fixing piece for fixing the pin (40), and the tip of this fixing piece (42) projects forward from the front end of the carriage (T). A connecting pin (43) for connecting to the vehicle is provided on the upper surface of the part.

FIG. 5 shows the operation of the front and rear cylinders (2) and the upper and lower cylinders (3). The front and rear cylinders (2) and the respective upper and lower cylinders (3) move in this order to convey the carriage (T). And then repeat this order. That is, first, the upper and lower cylinders (3) are activated to raise the hooks (30). Next, the front and rear cylinders (2) move forward. As a result, the hook (30) engages with the pin (40) of the truck (T) and conveys the truck (T) forward together with the pin (40). Then, at the same time that the tip of the truck (T) hits the stopper (51) of the truck positioning cylinder (5), the hooks (30) of the upper and lower cylinders (3) move down and the pins (40). And the carriage (T) is stopped from being conveyed. Then, the front and rear cylinders (2) retreat and return to their original positions. Then, this operation is repeated to sequentially convey the carriage (T).

FIG. 6 shows a state in which the carriage (T) is transported to a predetermined position and then connected to the self-propelled vehicle (6). When the carriage (T) is coupled to the self-propelled vehicle (6), the carriage positioning cylinder (5) ) Is activated to lower the stopper (51), and the self-propelled vehicle (6) sends it out from the device of the present invention. After being sent out, the trolley (T) located above the upper and lower cylinders (30 ') or (30 ") or both (30') and (30") is moved to the upper and lower cylinders (3) as described above. By the operation of the front and rear cylinders (2), they are conveyed to the stopper (51) of the carriage positioning cylinder (5).

In FIG. 6, reference numerals (60) and (60) in the figure denote guide portions of the self-propelled vehicle (6) for connecting the connecting pins (43) of the carriage (T), and the guide portions (60) (60). Is a pawl piece for holding the connection state of the guide pin (61) (62) fixed to the supporting piece (64) provided at the rear end of the self-propelled vehicle (6) in an expanded state and the connecting pin (43). (63) and (63).
