[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet material loading cart provided with a lifting stopper that can be raised and lowered as a means for fixing a sheet material loading position on the cart.

[0002]

[Prior Art]

 Conventionally, a sheet material loading trolley for loading and transporting a large amount of sheet material used in a press machine, etc. As a method for moving and fixing the loading position of the sheet material (material), a stopper is detached from four directions of the material. The method of doing was adopted.

In the air floater type stopper method, a plate is provided on the lower surface of the upper table, and the plate is placed on the lower table. When the compressed air is sent from the upper table side, the pressure of this compressed air causes the upper table to float and fix the sheet material position.

Further, in the air floating type free bear method, the hollow balls of the free bear are moved up and down by compressed air such as a cylinder head, and the sheet material position is fixed by fixing the free bear as necessary.

[0005]

[Problems to be solved by the device]

 By the way, in general, the method of attaching and detaching the stopper requires manpower, and there is a problem that extra work time is required. In the air floater stopper method, the plate on the lower table needs to be mirror-finished, which increases the labor for machining. In addition, when the floating air leaks from the side of the plate, the internal pressure decreases and the upper table lowers, which eventually causes the upper table to repeatedly repeat this lifting operation.

Further, in the air floating type free bear method, there is a problem that the internal machining becomes complicated and accordingly the price becomes expensive.

In order to solve the above problems, an object of the present invention is to provide a sheet material loading cart having a simplified structure, easy to handle, requiring no manpower, and saving working time. Is to provide.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a free bear which is provided on a trolley to smoothly move a sheet material to be loaded, and a free bear which is provided on the trolley and is vertically movable to fix the sheet material to a loading position. A sheet material loading trolley comprising an up-and-down type stopper.

[0009]

[Action]

 By adopting the sheet material loading truck of the present invention, a free bear for smoothly moving the loaded sheet materials is provided on the truck, and an elevating type stopper capable of fixing the sheet material at the loading position can be raised and lowered on the truck. By arranging it on the base, the structure is simplified, and it is easy to handle, does not require manpower, and saves working time.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a plan view of FIG. The sheet material loading cart 1 is mainly composed of a mounting base 3, a table 5, legs 7 and 7a provided between the mounting base 3 and the table 5 so as to be vertically movable, and a large number of free bears provided on the upper surface of the table 5. It is composed of a unit 9 and a lifting type stopper 11.

The mounting base 3 and the lower ends of the legs 7 and 7a are pivotally supported by shafts 13 and 13a, and a shaft 15 is pivotally supported at the intersection of the central portions of the legs 7 and 7a and The lower part of the table 5 is pivotally supported by shafts 17 and 17a. A table lifting hydraulic cylinder 19 is mounted between the legs 7 and 7a to lift the table 5. Further, the mounting base 3 is provided with a hydraulic unit 21.

As shown in FIG. 3, each free bear unit 9 has a proper number of free bears 23 arranged on the surface of a mounting case 25, and is mounted on the table 5 by mounting bolts 27.

Further, the elevating type stopper 11 is arranged together with the free bear unit 9 in an appropriate number on the table 5 so that the sheet material can be moved and fixed to the loading position on the carriage 1. Reference numeral 29 is a stacking sheet material stacked on the free bear unit 9 and the elevating stopper 11, and 31 is a pipe for preventing the plate 29 from falling.

FIG. 4 is a schematic configuration diagram of the lifting stopper, and FIG. 5 is a side view of FIG. In the elevating type stopper 11, the spring 35 is inserted into the stopper body 33, the T-shaped shaft 37 is placed on the spring 35, and the lid 39 is attached. Shaft guides 43 are provided on both sides of the stopper body 33 to prevent the urethane stopper 41 from shaking.

The urethane stopper 41 includes a mounting plate 45, a urethane plate 47 fixed on the mounting plate 45 with countersunk screws 49, and a guide shaft 51. The central portion of the mounting plate 45 is a T-shaped shaft 37. A coupling fitting 53 is provided that is integrally coupled to the tip of the. The guide shaft 51 slides in the shaft guide 43.

The free bear unit 9 is uniformly arranged around the elevating stopper 11. Further, 55 is a mounting screw for the stopper body 33 and the lid 39, 57 and 59 are mounting screws for the mounting base 61, 63 is a mounting screw for the lifting type stopper 11 on the table 5, and 65 is an intake port for compressed air. Is.

With the above configuration, since the elevating stopper 11 is normally pushed upward by the spring 35, the urethane stopper 41 comes into contact and pushes up the lower surface of the sheet material 29, and the sheet material 29 is pushed up. Block and fix the movement of.

In order to move the sheet material 29, compressed air is supplied from the air intake 65 of the stopper body 33, the T-shaped shaft 37 formed in a cylinder shape is pushed downward by the compressed air, and the spring 35 is moved. Compressed. Therefore, the sheet material 29 becomes free on the free bear 23 and becomes movable.

Therefore, the combination of the free bear 23 and the elevating type stopper 11 by the operation of compressed air by turning on / off a switch (not shown) causes the sheet material 29 on the sheet material loading carriage 1 to be fixed and moved at the loading position. Can be carried out freely, the handling of the sheet material during machining is easy, and the structure is simplified.

The present invention is not limited to the above-mentioned embodiments, but can be implemented in other modes by making appropriate design changes.

[0022]

[Effect of the device]

 As is clear from the above description, the carriage for loading sheet material according to the present invention is provided with a free bear for smoothly moving the loaded sheet material on the carriage, and is provided on the carriage so as to be vertically movable. By providing a lift stopper that can be fixed at the loading position on the carriage so that it can be lifted and lowered, the problems of the prior art can be effectively solved, its configuration can be simplified, and its handling is easy and requires manpower. Therefore, the working time can be saved.
