Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a supply section and a collection section for supplying magazines to a TC handler, and particularly relates to a mechanism that can accommodate magazines of different dimensions and cross-sectional shapes. 2 [Prior Art] Conventionally, when supplying ICC non-porous magazines, it was possible to stack magazines in multiple stages, and it was possible to supply and store a large number of magazines although it was compact.

However, since most of them use the separation claw method, 1
Many of the machines were dedicated to only one type of product, and even if they were capable of handling several types, there were a large number of setup points, which required a considerable amount of time and made it difficult to manage the setup parts. An example of a setup-type mechanism that can accommodate several types of magazines is a structure for storing and holding different types of magazines in an IC handler, as disclosed in Japanese Utility Model Application Publication No. 172390/1983.

[Problem that the invention seeks to solve]

Since the conventional technology is a multi-stack separation claw system, it is only possible to deal with differences in dimensions in the width direction among magazines of the same shape, and cannot deal with cases where the cross-sectional shape of the magazine is completely changed. In addition, the setup changes in the width direction also require replacement and attachment of setup parts, which requires a considerable amount of time and skill, and it is also difficult to manage the setup parts.

An object of the present invention is to provide a magazine feeding mechanism that can handle magazines with any difference in size and cross-sectional shape as long as they are within specifications with simple setup that does not require much time. .

[Measures to solve the problem 1 and layout are to eliminate the separating claws used in the conventional technology, and to install magazine receivers around the entire circumference of the belt or chain, etc. that match the maximum width of the magazine determined by the dimensional specifications. This is achieved by having a structure in which two sets of these are installed vertically facing each other, and by providing a sliding mechanism in the two sets of the above-mentioned standing mechanisms to make the interval between the two sets of belts or chains variable. be done.

[Effect]

Two sets of belts with magazine holders all around them, or
Magazines are supplied between the chains in a separated state one by one, thereby eliminating the need for separation claws that were conventionally required, so there are no restrictions on the shape and width of the magazines to be supplied. Further, since the distance between the two sets of upright mechanisms can be varied depending on the slide structure, the length of the magazine is also permissible as long as it is within the range of dimensional specifications.

Furthermore, since the magazine is fed to the mechanism in a separated state in advance, the magazine and the TC housed in the magazine are less likely to be damaged, and the magazine can be fed reliably.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on FIG. 1.2. FIG. 1 is a front view showing the basic structure of the present invention, and FIG. 2 is a plan view thereof.

Magazine receivers 2a, 2b are welded at regular intervals around the entire circumference of belts 1a, 1b), pulleys 3a, 3b,
It is erected and tensioned by 4a and 4b. Two sets of these structures are arranged facing each other, and the rotational drive given by the motor 15 is transmitted to the bevel gears 8 and 9 through the shaft 11, so that the belts 1a and 1b are rotated simultaneously in the rotational directions shown in FIG. make it possible to

Magazine guides 6a, 6b are magazines 23a, 23b.
When the magazine 23 is set in the magazine receiver 2a, it functions as a guide in the width direction, and regardless of the width of the magazine 23, the magazine guides 6a and 6b are used as a reference for feeding.

Moreover, since the magazine guide a, 61) has only one side, it is possible to supply not only from above but also from the side. Magazines 23a and 23b supplied and set to each magazine receiver 2a and 2b are connected to the motor 1,
By rotating belt 5 and feeding belts 1a and 1b one pitch, magazine rails 5a and 5b are sequentially moved from the bottom.
transported to.

Furthermore, one set on one side of the belt mechanism is fixed to a slide base 24 that can be slid in a straight line, so that even if the length of the magazine 23 changes, it can be handled simply by sliding the unit I-. The drive is transmitted by a key built into the bevel gear 9a, and a key slot 7 carved into the shaft 1].
This corresponds to the change in position when the unit is slid.

FIG. 3 shows an example of a magazine feeding device compatible with the present invention. When the magazine 23 set in the magazine receiver 2 is fed one pitch by the motor 15 and conveyed to the magazine rail 5, it is conveyed laterally by the magazine lateral feed claw 17. At this position, the device is transported by the device delivery unit 16 to the device receiver 19, and then supplied to the handler main body by another mechanism such as a robot. When the devices become empty, the magazine collection unit 18 collects the devices in multiple stacks in the magazine collection stockers 25a and 25b. The magazine collection stocker can be changed by the handle 21 according to the width of the magazine 23.

As a result, in the present invention, only the magazine receiver 19 needs to be replaced due to a change in the dimensions and cross-sectional shape of the magazine, and the rest can be handled by simply turning the handle.

In this embodiment, a belt is used as the supply mechanism, but a chain or the like may also be used. In addition, this belt or chain can have a structure that can be attached to and detached from the W firefly.
In some cases, it is possible to change the mounting pitch of the magazine holder provided on the belt, etc., and replace it with one that increases the number of magazines to be supplied.9 It can also be used in special-purpose machines where the dimensions of the magazine cannot be changed. It is possible.

〔Effect of the invention〕

According to the present invention, even if the types, dimensions, and cross-sectional shapes of magazines change, the setup work for the magazine supply section can be reduced, and one unit can accommodate many magazines of different types. Furthermore, since no setup parts are required, management of setup parts is easy. Furthermore, since the magazine is set in the main mechanism in a separated state before being supplied, damage to the magazine and the ICs housed in the magazine is less likely to occur, and the magazine can be supplied reliably. There are other effects.
