The cassettes are sent arranged in a line in the longitudinal direction with the title cards laid out underneath them, and the lyric cards that fall onto the undulating board 21, which is lying face down, are is connected to the cassette by.

When the pusher 22 descends from above and presses down the cassette, the title card is folded and stored in the case together with the lyrics card.

[The problem that the idea attempts to solve]

In the conventional lyric card supply device of the tape cassette packaging machine described above, the lyric cards are stacked diagonally on the belt conveyor 1 with the back side supported by the anti-fall table 3. After stopping the operation of the device and moving the fall prevention stand 3 while supporting the back side with hands, a new lyrics card is supplied between the lyrics card and the fall prevention stand 3.

Therefore, it is difficult to replenish the supply, and it is necessary to stop the operation of the machine each time, resulting in a disadvantage that the operating rate decreases.

Furthermore, when the lyric cards are sucked by the suction cup 4, due to the adhesive force between the lyric cards, the two lyric cards are simultaneously pulled out by the suction cup 4, and the two lyric cards are not peeled off by the claw 7 at the same time. May be supplied.

Alternatively, the lyric cards may not be sucked by the suction cup 4, or the suctioned lyric cards may be pulled away from the suction cup 4 by the claws 7, and the lyric cards may not be supplied. 2. Since it is only based on the guide plate 8, it may be fed diagonally.

As a result, there were drawbacks such as poor packaging, lower product yields, and lower machine operating rates.

The present invention is intended to solve the above-mentioned problems of the conventional lyrics card supply device for tape cassette packaging machines, and allows for easy replenishment of lyrics cards without stopping the operation of the machine. To improve the yield of defective packaging in which lyrics cards are fed at the same time, lyrics cards are fed diagonally, or are not fed at all.

[Means to solve the problem]

The present invention relates to means for a lyrics card feeding device for a tape cassette packaging machine to achieve the above-mentioned object. A suction cup that rotates and attaches to the bottom of the lyrics card,
When the suction cup rotates and attracts the bottom surface of the lyrics card, it is in the retracted position, and when the suction cup moves to suck the lowest lyrics card and curves the lyrics card, the separation claw is located at the bottom surface of the next lyrics card. , a gripper that grips one side of the lyrics card that is curved by the rotation of the suction cup, pulls out the lyrics card from the magazine by its movement, and then releases the lyrics card; and a gripper that releases the lyrics card released from the gripper. The gist of the invention is that it is provided with a pusher having an alignment means for sending the feed to the means.

[Effect]

In the lyric card supply device of the tape cassette packaging machine of the present invention, the lyric cards are vertically stored in the magazine that supports a part of the bottom surface, so when the magazine runs out, the lyric cards can be stacked on top of it. This can be done easily without stopping the machine.

Then, in order to bend the lowest lyric card by sucking it with a suction cup, only one lyric card is bent due to the stiffness of the lyric card.

Grasp one side of this curved lyric card with a gripper and pull it out of the magazine, but at that time, use a separating claw to hold down the next lyric card to prevent it from falling out due to friction with the lowest lyric card. To prevent.

The extracted lyric cards are aligned in their orientation by a pusher and fed into the feeding means.

[Example of idea]

An example of the implementation of the present invention will be described with reference to FIGS. 1 to 3, in which the lyrics card, the title card, and the case of a recorded tape cassette are shown.

a, The magazine is composed of an L pillar 31b that supports the remaining two corners, and a receiving plate 31c that supports a part of the bottom surface. can be adjusted to fit the size of the folded lyrics card.

Lyric cards are stacked vertically in this magazine 31 and supplied, and a part of the bottom surface is a receiving plate 31c.
Supported by

Reference numeral 33 denotes a suction cup attached to one end of an arm 35 that is rotatable on a support shaft 34, and is connected to the vacuum and the atmosphere via a tube (not shown), and the arm 35 is rotated by the operation of an air cylinder 36. It is rotated.

37 is a gripper composed of gripper pieces 37a and 37b, and the gripper 37b is connected to the gripper piece 37a.
The gripper piece 37 is pivotably mounted on the fulcrum 37c, and rotates about the fulcrum 37c as the air cylinder 38 provided on the gripper piece 37a operates.
The tips of a and 37b are close to each other.

The gripper pieces 37a are attached to an air cylinder 40 guided by a guide bar 39, and the operation of the air cylinder 40 causes the tips of the gripper pieces 37a, 37b to approach the suction cup 33.

Further, a stopper 37d is fixed to the gripper piece 37a to prevent the lyrics card from entering a certain depth or falling through the gripper piece 37b before it starts to be held between the gripper pieces 37b.

Reference numeral 41 denotes a detachment prevention claw (separation claw) which is pivotally supported on a shaft 42, and its tip is formed to prevent uncurved lyrics cards from slipping out from the magazine 31. Therefore, it rotates around the shaft 42.

Reference numeral 44 denotes a base for receiving the lyrics card, and on both sides thereof there are a guide plate 45 for aligning both sides of the lyrics card, a pusher 48 that is guided by a guide bar 46 and slides on the base 44 by the operation of an air cylinder 47, and a pusher 48 for holding the lyrics card. A stopper 49 is provided to support the back side.

The air cylinders 36, 38, 40, 43, 4

A switch 51 that is turned on and off is provided.

Furthermore, rollers 13 and 14 similar to conventional rollers are provided on the opposite side of the base 44 from the stopper 49, and belts 15 and 16 guided by a guide roller 19 are installed between the rollers 17 and 18.
It is the same as in the prior art that an undulating plate 21 having a guide 20 is provided below the side of the cassette 18, and a pusher 22 for pushing down the cassette and lyrics card is provided.

Next, the operation of the lyrics card supplying device of this tape cassette packaging machine will be explained.

First, the air cylinder 36 operates and the third air cylinder 36 operates.
As shown in FIG. A, a suction cup 33 is brought into contact with the bottom surface of the lowest layer of lyric cards stacked one on top of the other, and this is brought into a vacuum state to attract the lowest layer of lyric cards.

Next, as shown in FIG. 3B, the air cylinder 43 is operated to retract the lower end of the anti-falling claw 41, and the air cylinder 36 is operated in the opposite direction to move the suction cup 33.

Therefore, the lowest lyric card is placed on the receiving plate 31c.
The lyrics card is curved around one side, but the lyric card above it is not curved due to its stiffness, so only the lowest lyric card is bent and separated from the lyric card above it.

Thereafter, as shown in FIG. The tips of 37a and 37b are open.

At this time, the tip of the anti-falling claw 41 has returned from the retracted position due to the movement of the air cylinder 43 in the opposite direction.

Then, at the same time that the gripper pieces 37a and 37b grip the curved lyric card, the vacuum of the suction cup 33 is shut off, air is introduced, and the suction of the lyric card is released.

In this way, when the gripper 37 grips the lyric card by moving the air cylinder 38 in the opposite direction as shown in FIG.
As shown in FIG. 3E, the gripper 37 moves away from the magazine 31 and pulls out the lyrics card from the magazine 31.

At this time, even if the next lyric card is also pulled out due to friction with the lowest lyric card, since this lyric card is not curved, it is blocked by the lower end of the pull-out prevention claw 41. It does not come out of the magazine 31.

Therefore, of the stacked lyric cards, only the lowest one can be pulled out from the magazine 31.

When the lowest lyric card has been pulled out, the cylinder 38 operates in the opposite direction, and as shown in FIG.
The lyrics card is placed at base 44 in order to keep it away from the tip of the
fall towards.

At this time, both the left and right sides of the lyrics card are aligned by the guide plate 45.

Further, since the pusher 48 is projected above the base 44 by the operation of the air cylinder 47, the fallen lyrics card comes to rest on this pusher.

Then, the pusher 48 moves in the direction of retreating from above the base 44 due to the operation of the air cylinder 47 in the opposite direction.
8 and comes into contact with the stopper 49.

This corrects the position and inclination in the front-rear direction, and as the pusher 48 is further retreated, the entire surface of the lyric card is placed on the base 44.

Then, the pusher 48 pushes the lyrics card toward the rollers 13 and 14 as shown in FIG. Push it in.

Belts 15, 1 installed on rollers 13, 14
6 conveys the lyrics card and drops it from the rollers 17 and 18 onto the title card on the undulating plate 21, and the undulating plate 21 bends one side of the title card and stands up, and the lyrics card is placed on one side of the title card and the lyrics. Place the card in the cassette,
By lowering the pusher 22, the opposite side of the undulating plate 21 of the title card is bent, and the title card is stored in the case together with the cassette and lyrics card in the same manner as in the prior art.

[Effect of idea]

As mentioned above, in this invention, the lyric cards are stacked and stored in the magazine, so when the number of lyric cards runs low, all you have to do is stack new lyric cards on top of them. There is no need to stop the machine for replenishment, and replenishment is easy.

In addition, since the lyrics card on the bottom layer is sucked by a suction cup and bent, the lyrics card above it is not bent due to its stiffness, so that it can be separated.

Furthermore, when I grabbed a curved lyric card with a gripper and pulled it out, the lyric card above it was not curved, so I used a separating claw to hold it in place so that I could only pull out the bottom one. , it is possible to reliably supply lyrics cards one by one.

When the lyric card that has left the gripper is fed into the feeding means by the pusher, its tilt and position are accurately corrected by the alignment means, so that it is placed in a position where it completely overlaps the cassette and is removed from the case. There is no need for parts to protrude.

Therefore, the yield rate of defective packaging due to improper storage of a cassette with lyric cards attached to the case, or an excess or shortage of two lyric cards, etc., is significantly improved.

There will be no need to stop machine operation due to this.
This has the effect of improving the operating rate.
