Description

[Detailed explanation of the invention] This invention holds and transports a band-shaped member with multiple electronic components fixed to the band plate, and when stamping the product name, polarity, etc. on the component body, the component body is accommodated in the groove. The present invention relates to a pallet device that performs positioning, and is particularly intended to improve work efficiency when changing types of electronic parts in automatic stamping devices.

To stamp the product name, polarity, etc. on the main body of an electronic component such as a tantalum capacitor, count multiple electronic components 1 and place the tips of the lead parts 2 on the strip plate 3 at a constant pitch as shown in Figure 1. The belt-like member 4 is formed by joining together, and the both ends of the belt plate 3 of the belt-like member 4 are locked as shown in FIG.
It is placed on a pallet 5 which has locking claws 6, 6' for placing the parts and grooves 7 for accommodating and positioning the parts body 1' of the electronic parts 1. During the transportation, a marking device (not shown) stamps the product name, polarity, etc. on the component body 1.

A plurality of pallets 5 are mounted on a suitable conveyor at regular intervals, circulated endlessly, and near the starting end are strips of strip members 4 that have been individually conveyed on other conveyors. Both ends of 3 are locked with the locking claws 6, 6', placed on the pallet 5, the part body 1' is accommodated in the groove 7, transported, and the product name, polarity, etc. are marked on the part body 1. After stamping, the strip member 4 was carried out near the end and fed to another conveyor.

By the way, in the past, a manual stamping device was used to stamp the parts body 1 of the strip member 4 on the pallet 5, which resulted in low work efficiency, and there was no need to continuously convey the strip member 4 to the conveyor of the pallet 5. The number of strips 4 used to be attached was small, but in recent years automatic stamping devices have come to be used for stamping, which has improved work efficiency and made it possible to stamp the strips 4 continuously. A large number of pallets 5 are now mounted on a conveyor for continuous supply.

However, if only the same product type is to be stamped, it can be stamped without any problem, but if different product types are to be stamped, the mounting pitch to the strip plate 3 will be different due to the difference in the diameter of the component body of the electronic component, and this may be done on a pallet. 5, there was a problem in that the component body was not accommodated in the groove 7 and was misaligned, making it impossible to stamp.

That is, the same pallet 5 cannot be used to stamp different types of strip members, and when the types are changed, each pallet must be replaced with a pallet having grooves formed therein that match the mounting pitch of the component bodies.

However, it takes time and effort to replace the entire pallet 5.
Also, since there are many installed, it takes a lot of time to replace them.
There was a drawback that workability was significantly reduced.

Also, a large amount of storage space for pallets was required.

Therefore, as shown in FIG. 3, the pallet 5 is separated into a flat part 5a having a locking pawl 6.6' and a positioning part 5b having a groove 7, and both are integrally connected with a bolt 8. Only the positioning part 5b is replaced when the product type is changed.

However, the load applied to the component body 1' during stamping is as large as approximately 120 kg in total, and this load is of course received by the positioning part 5b, so the attachment between the positioning part 5b and the flat part 5a must be quite strong. For this purpose, the flat portion 5a and the positioning portion 5b are connected by a plurality of bolts 8, so that many bolts 8 must be removed and tightened during replacement, resulting in poor workability.

In view of the above-mentioned conventional drawbacks, this invention has been improved and eliminated by making it possible to replace grooves with different pitches with a single touch, and by creating a structure that can sufficiently withstand the load during stamping.

The configuration of this invention will be explained below according to the embodiment shown in the drawings.

In FIGS. 4 and 5, reference numeral 10 denotes a pallet device, which is made up of a fixed pallet 11 that is attached and fixed to a conveyor (not shown) and a rotating pallet 12 that is fixed and fixed to the rear of the fixed pallet 11. , the fixed pallet 11 has the upper surface 11

7', and positioning pins 16.16' and fitting holes 29.29' or 30.30' are fitted to prevent misalignment in the width direction, so they are separated during transportation. It is safe without any problems.

Further, since the rotating pallet 12 has the groove section (1) for accommodating the component body 1' supported by the stepped portion of the fixed pallet 11, it can sufficiently withstand the load applied to the component body 1' during stamping.

As explained above, this invention consists of a fixed pallet in which a step is formed by cutting out the rear upper surface in the width direction, and a corner on one diagonal of the side surface of the prismatic body is notched in the width direction to engage with the step in the fixed pallet. A rotating pallet that has a locking stepped part formed thereon, and a plurality of grooves with different pitches formed perpendicularly to the width direction on the top and bottom surfaces of the prismatic body, excluding the engaging stepped part, and a fixed pallet that holds the rotating pallet. Because the mounting pitch differs depending on the type of strip member to be stamped, all that is required is to rotate the rotating pallet when replacing the pallet, and the pallet can be replaced with a single touch, making it easy to use the conveyor. Even if a large number of pallet devices are attached to the top, it is possible to change types in a short time, improving work efficiency.

In addition, since the rotating pallet is supported by the wide horizontal surface of the fixed pallet, it has high rigidity and can withstand the load during stamping, and the relationship between the positioning pin and the fitting hole ensures high positioning accuracy and no misalignment. It can be stamped.

Note that the present invention is not limited to the above-mentioned embodiments; for example, the holding means may be a combination of magnets, positioning pins, and connecting rods, or may be any one of them or any combination thereof, and may further include a support bracket and a rotating shaft. The rotating pallet is held on the fixed pallet by bending the ends of the connecting rods inward into an L-shape, or by forming them into a U-shaped integral part, so that the stepped part of the fixed pallet and the rotating pallet are held together. It can be secured and fixed by pressing against the stepped portion.

This makes it easy to replace the rotating pallet, and
Furthermore, pallets can be replaced in a short time even for a large number of strip members having different pitches.
