Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mobile trolley with an automatic positioning device, and more specifically, to a mobile trolley having a simple structure automatic positioning mechanism, in which the mobile trolley directly engages with an automated machine or the like. It is used when it is used in.

[0002]

[Prior art]

 Conventionally, positioning of a load on a moving carriage is often performed by a positioning device installed on the floor after the carriage is stopped.However, since the positioning device is complicated, it can be moved to the floor. A complicated positioning device was installed at each stop position of the bogie.

[0003]

[Problems to be solved by the device]

 As mentioned above, in the past it was necessary to install a complicated positioning device at each stop position on the floor, so it was restricted by the floor space, and the positioning device on the floor has many operating modes. Due to its complexity, it is prone to failure and has poor maintainability.

The present invention is intended to solve the above problems. That is, an object of the present invention is to provide a moving carriage with an automatic positioning device that can carry a load and can easily position the load at a stop position of the carriage.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention relates to a mobile trolley of a type in which a load is moved and the load is positioned in a stationary position at a stop position. An elevating device provided on an upper part, and a load receiving member is placed on the elevating device, and the load receiving member has a concave or convex bottom. A lower frame, and further, on the floor surface at the position to be positioned, there is a convex or concave portion that fits into one of the concave and convex of the lower frame. And

[0006]

[Action]

 According to the present invention, in a mobile trolley of a type in which a load is moved and the load is positioned at a fixed position at a stop position, the mobile trolley has a traveling wheel provided at a lower portion thereof and a lifting wheel provided at an upper portion thereof. And a load-receiving member mounted on the lifting device, and the load-receiving member has a lower frame having a concave or convex bottom. In addition, since the floor surface at the position to be positioned has a convex or concave portion that fits with either the concave or convex portion of the lower frame, In this case, the elevating device is extended to lift the load receiving member, and then the elevating device is lowered at the trolley stop position so that the bottom frame of the bottom frame of the load receiving member has a concave or convex shape on the floor surface. You can position the load by fitting it in the concave part.

Therefore, most of the load positioning device is on the moving carriage side, and only the convex or concave portion is on the floor surface side, so there are few restrictions on installation on the floor surface and few failures. .

【Example】

 FIG. 1 is a front view showing an embodiment of the present invention. In FIG. 1, reference numeral 1 is a moving carriage, 2 is a traveling wheel provided at a lower portion of the carriage 1, 3 is a lifting device provided at an upper portion of the carriage 1, and 4 is the platform via the lifting device 3. A load receiving member mounted on the vehicle 1, 5 is a load, 6 is a guide for preventing deviation during loading, 7 is a portion where the lifting device 3 and the load receiving member 4 are in contact, 8 is a lower frame of the load receiving member 4, and 9 Is a concave portion of the bottom portion of the lower frame 8, 10 is a floor surface, and 11 is a convex shape that is fitted to the concave portion 9 provided on the floor surface 10 It is a part.

A portion 7 where the lifting device 3 and the load receiving member 4 are in contact with each other is horizontally slidable. Further, the convex portion 11 is provided on the floor surface 10 at the position to be positioned. The load receiving member 4 may be a conveyor or the like, but in this embodiment, it is a fixed pedestal. Further, although the bottom portion of the lower frame 8 has the concave portion 9, it may be changed to a convex shape. In that case, the convex portion 11 provided on the floor surface 10 must be concave.

In the mobile carriage with the automatic positioning device configured as shown in FIG. 1, as shown in FIG. 2, the material and the load 5 of the parts in which the mobile carriage 1 is in direct contact with a machine such as a press die or robot. Transport and stop at the stop position. In this state, since the lifting device 3 is in the raised position, the load receiving member 4 is placed on the trolley 1 via the lifting device 3.

After the carriage 1 stops at this stop position, as shown in FIG. 3, the elevating device 3 descends to the lower position. Then, the concave portion 9 of the bottom portion of the lower frame 8 of the cargo receiving member 4 and the convex portion 11 of the floor surface 10 overlap with each other to position the cargo receiving member 4. In this way, the load 5 is positioned.

Further, since the load receiving member 4 has the guide 6 for preventing the shift at the time of loading, the load 5 is always stable, and the portion 7 where the load receiving member 4 is in contact with the lifting device 3 is horizontal. Since it is slidable, the positioning can be easily performed even if there is some deviation between the lifting device 3 and the load receiving member 4. That is, the state of FIG. 2 is easily changed to the state of FIG.

[0013]

[Effect of device]

 As described above, according to the present invention, in a mobile trolley of a type which moves a load and positions the load at a stationary position at a stationary position, the mobile trolley has a traveling wheel provided at a lower portion thereof. An elevating device provided on an upper part, and a load receiving member is mounted on the elevating device, and the load receiving member has a lower portion having one of a concave shape and a convex shape. Since the frame has a frame, and the floor surface at the position to be positioned has a convex or concave portion that fits in correspondence with either concave or convex of the lower frame, When moving a load, the lifting device is extended to lift the load receiving member. Then, the elevating device is lowered at the trolley stop position, and the concave or convex portion of the bottom of the lower frame of the load receiving member is fitted to the convex or concave portion of the floor surface, whereby the load can be positioned.

Therefore, most of the load positioning device is on the moving carriage side, and only the convex or concave portion is on the floor surface side, so there are few restrictions on installation on the floor surface and few failures. . Therefore, the facility cost and the maintenance cost can be reduced.
