Abstract

PURPOSE:To cope with multiple-type production by using two-layer pallets: the lower pallet for common use, and the automatically replaced upper pallet for each machine type, in a pallet device allowing the assembly of products with an automatic machine. CONSTITUTION:A memory pin 3 and a position setting pin 5 are fitted to a commonly used master pallet 2, and a machine type judging through hole 9 is bored. A guide hole 6 and a machine type judging through hole 8 are bored on an automatically replaced slave pallet 4. When starting the assembly of a desk calculator main body section 1 via the operation of this device, a transfer signal is applied to the memory pin 3 of the master pallet 2, a slave pallet 4 in response to the signal is carried out from a stocker for line slave pallets 4 and is mounted on the master pallet 2. Next, the desk calculator main body section 1 detecting the slave pallet 4 with a reflective photoelectric cell and judging the machine type is mounted on the slave pallet 4.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a pallet device that enables automatic machine assembly of products. 2 that can correspond to
This invention relates to a layered parent-child pallet device.

Conventional structure and its problems Conventionally, in the manufacturing process of calculators, calculators were produced in a mix of many models, and even if automatic assembly of calculators was considered, there were so many different models that it was impossible to keep up with just changing the pallet setup. However, because common pallet equipment was not available, pallets hindered assembly automation. In addition, the model discrimination is also done manually, and there is a lot of work loss as people make selections each time, making it unsuitable for continuous automatic production.

Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks, and is a pallet device in which a common parent pallet is provided and child pallets are exchanged according to the model. is stored in the stocker, and can be automatically replaced according to the model identification, and the parent pallet is characterized by a constant board, making it a two-layer parent-child pallet device that can support multiple models. This is what we provide.

Structure of the Invention The present invention includes a plate-shaped two-layer pallet, and the upper child pallet regulates the lower surface and outer peripheral edge of a substantially thin plate-shaped object placed on the child pallet main body. It has a holding part, a positionable guide hole part that allows the child pallet to be attached and removed freely, and a through hole for identifying the model that extends from the child pallet to the parent pallet 7). On the other hand, the parent pallet has a memory pin for model switching, and a notch is provided in the main body of the parent pallet to enable the marking of the parent pallet, and a position adjustment pin when combined with the child pallet. It is characterized by having
It is possible to realize an optimal pallet device that enables automation in the assembly process of approximately thin plate-shaped parts such as calculators.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In the figure, 1 is a calculator main body, 2 is a parent pallet, 3 is a memory pin, 4 is a child pallet, 5 is a positioning pin installed on the parent pallet 2, 6 is a guide hole on the child pallet 4, 7 is a notch in the main body of the parent pallet 2, and 8 is a through hole provided on the child pallet 4 for model identification. Reference numeral 9 denotes a through hole for model identification, which is partially provided on the parent pallet 2 through the child pallet 4.

The operation of the pallet device configured as described above will be described below.

When starting the assembly of the calculator body 1, the switching signal is sent to the parent pallet 2.
When applied to the memory pin 3 above, the signal is automatically read from there, and the child pallet 4 is carried out from the stocker for the child pallet 4 on the line and transferred to the parent pallet 2 as shown in Figure 4.
The child pallet 4 is loaded by passing through the guide hole 6 of the child pallet 4 through the upper position regulating pin 6. Next, the calculator body 1 is placed on the child pallet 4 by the robot (not shown). The parent pallet 2 is also a substrate to be transported, and the notch 7 is used to regulate the parent pallet 2 itself.

The model of the calculator 1 is determined by having a plurality of holes 8 made in the loaded child pallet 4 and detecting the holes with a reflective phototube. When changing the model, a signal is similarly applied to the memory pin 3 on the parent pallet 2, and another child pallet 4 is taken out from the stocker and replaced, allowing the pallets to be sequentially changed on the automated line.

As described above, according to this embodiment, even if the child pallet 4 is manufactured for multiple models, the parent pallet can be used in the same shape, and it is possible to automatically take out and load the child pallet. It has added values such as transport one position regulation, memory operation, and model identification, and can provide an optimal pallet device for use in assembling ultra-thin parts such as calculators.

Effects of the Invention As described above, the pallet device of the present invention includes a plate-shaped two-layer pallet, and a child pallet for holding an object to be attached is manufactured according to the model, and a parent pallet serving as a substrate is common. You can deal with this. Father-son pallets are loaded through the positioning pins of the parent pallet, so there is no fear of misalignment.
Moreover, it can be manufactured easily and inexpensively. A pallet with a simple structure that can handle multiple models and is suitable for automation, such as through-holes for model identification on the father and child pallets, which can be automatically identified from multiple patterns of combinations of holes and non-holes. It is ideal as a device.
