Description

[Detailed Description of the Invention] This invention relates to a cassette insertion device that automatically inserts a magnetic tape cassette into a jig.

Parts such as a separate sheet, a tape guide roller, a magnetic shield plate, and a spring plate with a butt are sequentially assembled into the lower case of the magnetic tape cassette transported by the transport mechanism, and after the upper case is fitted to the lower case, When the work of joining the upper and lower cases together using tapping screws or the like is performed automatically, the above-mentioned parts cannot be properly assembled unless the cassette is positioned and transported properly.

Therefore, if the cassette is transported alone, since the cassette itself is lightweight, it is likely to be displaced and misaligned due to vibration or impact, making it difficult to assemble the above-mentioned parts.

In order to solve this problem, a method has been adopted in which the cassette is transported while being inserted into a jig.

The second station 19 is the first station 5.
At the downstream side of the jig conveying path 1, opposing guide surfaces 20, 20 are provided, as shown in FIG.

The guide surfaces 20.20 are opposed with an opposing span W2 that is somewhat larger than the opposing span W1 of the first station 50 guide surface 13.13.

Therefore, in this position, the magnetic tape cassette 4
slopes forward and downward, as will be described later.

The second station 19 is provided with a second suppression mechanism 21 .

The second pressing mechanism 21 is used to push down the cassette 4 which is temporarily inserted into the jig 2 in a forward downwardly inclined manner to properly insert the cassette 4. A push-down member 2 that looks like a roller is suspended from a suspension member 23 provided at the lower end.
It is composed of 4.

Reference numeral 25 denotes a stopper, which is provided close to the first station 5 on the downstream side to appropriately position and stop the magnetic tape cassette 4 with respect to the jig 2 within the first station 5.

The second station 5, 19 is properly positioned and stopped.

As shown in FIG. 5, the jig 2 has a pair of left and right round shaft-shaped protrusions 2a, 2afr: standing high at the center of the top surface, and a pair of left and right pins 2b, 2b' standing low at the front of the top surface. It has a plate spring 2C attached to the rear of the top surface, and the top i
d Guide vanes 2d, 2d are provided in the center of each projection 2a, 2a+j so as to be movable in the radial direction.

As shown in FIG. 6, the magnetic tape cassette 4 is composed of a lower case 4A and an upper case 4B fitted into the upper case 4A.

4B is provided with a pair of drive shaft insertion ports 4C and a reference hole 4D.

In the above configuration, the jig 2 is conveyed intermittently on the jig rapid path 1 in the direction of arrow A1 in FIG. 21 comes into contact with the stopper 26 and stops at the proper position corresponding to the second station 19, and the second jig 22 adjacent to the jig 21 stops at the proper position corresponding to the first station 5. .

At the same time, the most advanced cassette 41 of the cassettes 4 on the cassette transport path 3 is carried out from the outlet 3a to the first station 5, contacts the stopper 25 and stops at a proper position, and the lock holding mechanism 6 is locked. It is held horizontally on a holding plate 12.

In this case, both the jig 2° and the cassette 41 are regulated in their longitudinal direction by the stoppers 25 and 26, and the width direction of the cassette 410 is guided by the front end surface 4a and rear end surface 4b of the cassette 41 as shown in the figure. Since it is held by the retaining plate 12 in contact with the surface 13.13, it is horizontal as described above, and as shown in Figures 7a and 8a above, the protrusion of the jig 2□ The axis X1 of 2a, 2a, the axis X2 of the drive shaft insertion port 4C of the cassette 4, the axis Y1 of the pins 2b, 2b, and the axis Y2 of the reference hole 4D are on the same line.

Next, the actuator 16 in the first pressing mechanism 15 of the first station 5 operates, and this operation causes the pressing member 18 to press the upper case 4B of the cassette 41, so that the lower surface of the lower case 4A engages with the retaining plate. A pair of movable arms 10.1
0 is opened as shown in FIG. 8b against the spring force of the spring 9.

Therefore, the cassette 41 falls horizontally using the guide surface 13.13 as shown in Figures 7b and 8c.
Protrusions 2a, 2 are formed on the periphery of the drive shaft insertion hole 4C of the cassette 41.
The state in which the guide blade 2d of a is in contact, that is, the protrusion 2a,
2a is temporarily inserted into the drive shaft insertion hole 4C.

In this temporary insertion state, both front and rear end surfaces 4a of the cassette 41,
4b comes into contact with the guide surface 13.13, so that it is in a horizontal state.

Once the above-mentioned temporary insertion is completed, the first suppressing mechanism 15 returns, the stopper 26 is released, and the conveying mechanism operates to move the jig 21y22 one pitch, that is, the jig 21,
22 in the direction of the arrow A, the jig 21 is sent downstream from the stopper 26 as shown in FIG. 1C, the jig 22 is stopped at a position corresponding to the second station 19, and the next The feeding jig 23 is stopped at a position corresponding to the first station 5, and the second cassette 4
2 is held on the lock holding plate 12 of the lock holding tank 6 of the first station 5.

The opposing spans W2 of the guide surfaces 20 and 20 of the second station 19 are connected to the first station guides h13 and 13.
Since it is set somewhat larger than the facing span Wl of the cassette 410, both front and rear end surfaces 4a, 4b and the guide surface 20.
A clearance is formed between 20 and 20.

For this purpose, the cassette 41 is tilted forward and downward by its own weight, as shown in FIG. 8d, and the pins 2b, 2b are temporarily inserted into the reference hole 4D.

Afterwards, the second suppression mechanism 2 of the second station 19
The actuator 22 of No. 1 operates to press the upper surface of the upper case 4B with the push-down member 24, and as shown in FIG. 1d and FIG.
The pins 2b and 2b are inserted into the drive shaft insertion port 4C and the reference hole 4D, and an appropriate insertion state is obtained in which the rear end surface 4b is latched onto the leaf spring 2C.

At this time, the cassette 4° is pushed down to the jig 23, which is stopped at a position corresponding to the first station 5, and temporarily inserted into the cassette 41 in a rotating motion.

Further, the stopper 26 is opened, the conveyance mechanism operates to convey the jigs 22 and 23 one pitch, and the jig 22 is sent out downstream of the stopper 26, that is, to the parts assembly line (not shown), and the jig 23 is transferred to the second The cassettes 4 are successively inserted and sent to the next process by repeating the above operations.

The cassette 4 sent to the next process is transported at a predetermined position with only the upper case 4B removed by a vacuum suction mechanism, the lower case 4A is opened, and predetermined parts are sequentially assembled into the upper case 4A. is fitted.

As explained above, this invention has protrusions 2a and 2 of jig 2
A and pins 2b and 2b are not inserted into the drive shaft insertion hole 4C and reference hole 4D of the cassette 4 at once, but after temporarily inserting the protrusions 2a and 2a into the drive shaft insertion hole 4C, the tilting is performed at the second station 19. Since the pins 2b and 2b are temporarily inserted and the pins 2b are then completely inserted, the insertion can be performed smoothly and accurately without malfunction, improving work efficiency and preventing damage to the cassette. There are advantages such as

In the above implementation, an example is described in which the cassette 4 in which the upper case 4B is fitted to the lower case 4A is inserted into the jig 2, but this invention is not limited to the above-mentioned arrangement. Even if only the lower case 4A is transported and inserted into the jig 2, the same effect can be obtained.
