Description

[Detailed Description of the Invention] [Field of Application of the Invention] This invention relates to a magazine that accommodates a large number of video tape recorder heads (VTR heads) and facilitates handling of the VTR heads during inspection and assembly.

[Background of the idea]

Magazines of this type can be used, for example, with rotating heads.
When pairing the video heads of a VTR, that is, when combining multiple video heads with the same electrical characteristics that are incorporated into one rotary head, it is necessary to accommodate the heads before and after inspection, and to combine them. It is used to house a new head.
Each magazine is identical in size and shape;
It is designed so that it can be used mutually in each work process.
However, since it is not possible to distinguish between the types of heads housed, the current situation is that it is up to workers to manage the heads by placing them in different locations or attaching paper, etc.

[Purpose of invention]

The present invention can standardize and classify and display not only the types of VTR heads housed, but also their electrical characteristics, and can also be machine readable. It provides magazines for VTR heads.

[Summary of the idea]

In the magazine of the present invention, the magazine itself is equipped with a means for displaying the type of VTR head, electrical characteristics, etc., and this means is provided with a plurality of heads arranged close to each other and outside the pit group. It is characterized in that it is composed of pin holes and a number of pins that correspond to the number of pin holes and that are detachable from the pin holes, and that the above-mentioned display is made by the combination of pins on the pin holes. According to the present invention, when the number of pin holes and pins is six, for example, 64 separate indications are made, including when all the pins are not fitted into the pin holes and when all the pins are fitted. This allows for detailed classification by head type, electrical characteristics such as output and inductance.
Moreover, since the display can be standardized and is done for each magazine, it is clear to all workers what type of bed is stored.
Re-inspections and incorrect work can be eliminated.

Each combination of pins can be machine read, for example, by scanning a reflective light sensor along the direction of the pin holes, or by aligning the pin holes with the scanning direction of the reflective light sensor. Therefore, the inspection equipment and assembly equipment can automatically select the work procedure according to the VTR head accommodated.

In the present invention, pin holes may be provided in multiple locations apart from each other, for example, at both ends of a rectangular magazine, so that the operator can easily assemble the pins no matter which direction the magazine is oriented. Alternatively, it can be read by a sensor.

An example of the VTR head magazine of the present invention is as follows:
A description will be given below with reference to the accompanying drawings.

[Example of idea]

In Figures 1 to 3, the magazine body 1
1 is made of a synthetic resin molded product, and pits 12 for accommodating VTR heads are arranged in a grid pattern, for example.
There are 50 of them. Each pit has the form of a rectangular recess, and the VTR head 13 is supported by the magazine by falling into this pit. A hole 14 is provided between the pits. This hole is for the chuck that takes out the head in the pit. A pair of pins 15 are provided diagonally on the top surface of the main body 11, and a pin 1 is provided on the bottom surface of the main body 11.
A hole 16 is provided corresponding to the magazine body 5 so that these fit together when the magazine bodies are stacked. Further, a hole 17 is provided in the main body 11 in line with the hole 16, so that when the magazine is loaded into an inspection device or the like, the magazine can be positioned by fitting into a pin on the inspection device.

As mentioned above, the magazine according to the present invention has a means for classifying and displaying the type and electrical characteristics of the VTR head accommodated in the magazine pit, that is, the pin hole 2
1 and a pin 22. The pin hole 21 is
Six pieces are arranged in a straight line, and they are provided at both ends of the magazine body symmetrically with respect to the central axis of the magazine body. The pin hole itself consists of a blind hole integrally molded with the pit. Although two pins 22 are shown for each pin hole row in the drawing, there are actually six pins 22 for each pin hole row. Each pin has a diameter that allows it to fit somewhat into the pin hole 21;
and a height that is flush with the magazine body when mated. And pin 22
The end surface exposed from the pin hole in has a light reflectance different from that of the surface of the magazine body. Such a classification display means uses a single pin 22.
are fitted into the pin holes 21 in sequence, so that 6
By using two pins, you can display 15 different ways, by using three pins, you can display 20 different ways, and by using four pins, you can display 20 different ways.
15 different displays can be made, and 8 different displays can be made using 5 pins. A total of 64 including those in
Different street representations can be made.

This magazine can be used, for example, with a rotating head type VTR.
It is used in automatic inspection equipment that measures the electrical characteristics of video heads in the industry and combines heads with the same rank of electrical characteristics. This automatic inspection device includes, for example, a robot 31 as shown in FIG.
a transport section including a measuring section 32, and a robot 33.
It is equipped with a pairing part including. One of the video heads in a two-head VTR, ie, the first head, is accommodated in a magazine 30 according to the present invention, identified by a pin 21, and loaded onto a table 34 of a transport section at the position shown by the chain line. table 34
When the magazine is moved to the robot 31 side, the robot sets one magazine in the head supply position 40 of the classification table 35. Next, the heads in the magazine are sent one by one to the measuring section 32. The measurement unit measures the heads in each magazine one by one, and the robot 31 stores the heads in the magazines 30 on a table 35 divided according to the measured electrical characteristics. Thereafter, when the magazines are full, the robot 31 places each magazine on the table 35 on the table 36, and the table 36 transports them to the robot 33 in the magazine pairing section. The robot 33 places each magazine containing heads of the same characteristics on a table 37, and the table 37 moves along the chain line position to stock the first head. The other image head is similarly measured and classified, and is stored in a magazine according to its electrical characteristics.

When this second image head is transported by the transport table 36, the robot 33 transports the magazine to the table 37, and then, when the first and second heads with the same rank of electrical characteristics are ready, the robot 33 transfers the magazine to the table 37. Place the head and second head magazines on table 38.
Set to . Next, an empty magazine is set on the table 38, and the first and second heads are spared there. The full magazine on table 38 is conveyed to finished product table 39. The magazine containing the pair of first and second heads is removed from the device at the position shown in phantom on the table 39.

The magazine according to the present invention is not only used for accommodating and transporting a large number of image heads in the transport section and the pairing section of such inspection equipment, but also the magazine is By reading the combination of the pins 21 above, it is possible to determine whether the first or second head is being sent, and the necessary work can be automatically performed, and even in the event of a power outage, etc. stored in each magazine even when operation is interrupted.
Since the types of VTR heads are distinguished by pins 22, operation can be restarted immediately without confusion.

[Effect of idea]

As mentioned above, the VTR head magazine of the present invention can display the type of head accommodated, its electrical characteristics, etc. Moreover, since the display is made by a combination of pins, it is possible to display different magazines while working. It is possible to easily distinguish even if there is a mixture of materials, and it can be read by a machine, so inspection, assembly, and related work can be automated.
