Description

[Detailed Description of the Invention] The present invention relates to a pallet for conveying blank materials.

Material supply in press working is broadly divided into coil material and material whose external shape has been formed to a certain degree (generally referred to as blank material). The pallet of the present invention is used as the latter blank material.

The purpose of the pallet is to transport blanks stacked high into a fixed position in the material supply device in a fixed direction, and also to prevent the materials from shifting on the pallet.

Since the shape and orientation of the blanks vary from product to product, the pallet is either adapted to accommodate these changes or is dedicated to a particular blank.

Of these, the latter is only used in special cases, and generally has a structure that can accommodate changes in shape and direction. Figures 1, 2, and 3 show pallets that are currently widely used in factories.

In the pallet of the type shown in Fig. 1, a T-groove is provided in the pallet base plate 1 as shown in Figs. It has a structure that allows it to be tightened in an appropriate position.

In addition, the pallet of the type shown in Fig. 4 has a structure in which screw holes are provided in the pallet base plate 1 in place of the T-grooves shown in Fig. 2, and the guide rods 2 are screwed into appropriate positions.
The structure is such that one skilled in the art can easily conceive of a pallet of the type shown in the figure.

Generally, four or more guide rods 2 are required to regulate the shape and direction of the blank material 5. Furthermore, in order to accurately feed blanks one by one from a pallet to a transfer press or other automatic conveyance device, accuracy in the position and direction of the blanks 5 with respect to the pallet is required. The pallet of the type shown in Figure 1 requires a lot of effort to tighten the bolts according to the shape, and the pallet of the type shown in Figure 4 has threaded holes, making it difficult to accommodate minute changes in shape.
Adjusting the position of the guide rod 2 is a tedious and difficult task, and automation is also difficult.

The present invention aims to eliminate these drawbacks and provide a pallet for conveying blank materials that can quickly and freely adapt to the shape of blank materials in order to accurately and quickly supply blank materials to transfer presses and other automatic conveyance devices. It is something to do.

The structure of an embodiment of the present invention is shown in FIGS. 5, 6, 7, and 8.

7 is a box-shaped case made of a bent board, 8 is a guide rod,
9 is a low alloy alloy, 10 is a roller for moving the case, 1
1 is a case guide plate, and 12 is a double pipe for heating and cooling. A low-fusion metal 9 is placed inside the case 7. A plurality of guide rods 8 for positioning the blank material 5 are erected at positions corresponding to the shape and direction of the blank material 5, with their lower ends buried in the low alloy metal 9. A protrusion for receiving a blank material 5 is provided around the central hole 13 of the case 7, and the blank material is stacked on the protrusion part. Also, inside the case 7 is a double pipe 1 for heating and cooling.
2 is disposed and is buried in the low alloy metal 9.

The low alloy metal 9 is melted in a short time by the internal heating of one of the heating pipes 12a, so the guide rod 8
The position can be easily adjusted. Furthermore, by flowing the coolant through one of the cooling pipes 12b, the guide rod 8 can be quickly cooled and solidified after the positioning of the guide rod 8 is completed.

Incidentally, the guide rod 8 is provided with a protrusion 8a or a recess 8b at one end, as shown in FIG. 7, to prevent it from easily coming off.

The center hole 13 of the case 7 is a square hole, and is structured to fit into the square portion 14b of the template 14.

The shaped portion 14a of the template 14 has the same shape and dimensions as the blank material 5, and the blank material can be easily removed by fitting the square portion 14b into the square hole of the case and positioning the guide rod 8 along its outer periphery. Set the shape and direction of

In addition, multiple pallets of the present invention are prepared, blanks are stored externally, and the case moving roller 1 is used.
0 and a case guide plate 11 (not shown).

Since the present invention has the above-described structure and operation, the present invention produces the following effects.

1. Since it is made of a thin pallet base plate 1 and a low alloy metal 9, the whole is light and easy to handle.

2 Heating and cooling can be done quickly with the double pipe 12, regardless of the position of T-slots, screw holes, etc.
The guide rod 8 can be set at the most appropriate position that matches the shape, and there is no need to tighten bolts, so the positioning work of the guide rod 8 is easy and can be easily automated.

3. Since the template 14 is used when positioning the guide rod 8, the shape and direction of the blank material can be set accurately at the same time.

4. Since the time for positioning the guide rod 8 is shortened, one pallet can handle many types of blank materials. As a result, the total number of pallets can be reduced.
