Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a taping component supply device that intermittently conveys components stored in a tape at regular intervals and supplies the components to a predetermined position.

2. Description of the Related Art Conventionally, as a taping component supply device, a tape is intermittently conveyed, a cover tape on a tape surface is peeled off before a predetermined component supply position, and the peeled cover tape is rotated by a ratchet mechanism. 2. Description of the Related Art It is known to take up a component on a reel and then take out the component at a predetermined position.

In such a conventional taping component supply device, a ratchet mechanism is used for a take-up mechanism that intermittently winds the peeled cover tape. There is a problem in that the teeth of the ratchet wheel rub against each other, generating noise peculiar to the ratchet mechanism. For this reason, when the component supply speed is increased, the ratchet claws and the teeth are liable to be worn, and there is a disadvantage that the supply speed which can be employed is limited and the speed cannot be increased.

Means for Solving the Problems The present invention provides a tape sending means for intermittently transporting a tape containing a plurality of components at equal intervals, a peeling means for peeling off a cover tape of the tape, and a peeling cover tape. In a taping component supply device including a winding device for winding and supplying a component to a predetermined position, the winding device includes a winding reel, a ratchet wheel that rotates integrally with the winding reel, and a winding device. A ratchet arm pivotally supported by a common axis of the reel and the ratchet wheel; and a take-up lever pivotally supported by the common axis, and a tip end of the ratchet arm is detachably attached to a tooth portion of the ratchet wheel. A ratchet pawl to be engaged is pivotally supported, and a projecting portion that releases the ratchet pawl from the tooth portion when the ratchet pawl comes into contact with the ratchet pawl is provided at a tip end of the winding lever. And a spring is provided between the ratchet arm and the take-up lever to bring the two close to each other, and when the take-up lever is driven in the reverse take-up direction, the protrusion comes into contact with the ratchet pawl and the ratchet When the ratchet arm rotates together with the take-up lever with the pawl released from the teeth, and the take-up lever is driven in the take-up direction, the protrusion separates from the ratchet pawl and the ratchet pawl meshes with the teeth. And
The ratchet wheel is driven to rotate in the same direction while the ratchet arm rotates toward the winding lever by the spring.

According to the taping component supply device of the present invention, when the winding lever is driven in advance in the reverse winding direction to drive the ratchet wheel to move the ratchet arm in the direction opposite to the winding direction of the cover tape, The ratchet claw at the tip of the ratchet arm is pushed by the protrusion of the take-up lever, and the ratchet claw moves while being separated from the teeth of the ratchet wheel, so that the ratchet claw does not rub against the teeth of the ratchet wheel, No noise specific to the ratchet mechanism is generated, and ratchet claws and teeth are not worn.

On the other hand, when driving the winding lever in the winding direction,
The protrusion is separated from the ratchet pawl, the ratchet pawl meshes with the tooth part, and the ratchet arm is rotated toward the take-up lever by the spring, so that the ratchet wheel is driven to rotate in the take-up direction, and the take-up reel is driven. Can also be rotated in the same direction to wind up the cover tape.

An embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, a take-up reel 2 and a ratchet wheel 3 are rotatably mounted on a main body 1 of a supply device via a common shaft 4 thereof.

The common shaft 4 supports a rectangular take-up lever 5 and a ratchet arm 6 that are pivotally supported by the common shaft 4. The winding lever 5 is supported by the common shaft 4 at the center thereof, and a driving force from a driving source (not shown) acts on its upper arm 5a. The ratchet arm 6 projects in the same direction as the lower arm 5b of the take-up lever 5, and a projecting portion projecting toward the tip of the ratchet arm 6 at the tip of the lower arm 5b of the take-up lever 5. 5c is formed. Further, a pin is provided at the tip of the ratchet arm 6.
A ratchet pawl 7 pivotally supported by 7a and urged by a torsion spring (not shown) toward the tooth portion 3a of the ratchet wheel 3 is provided.

Further, the lower arm 5b of the take-up lever 5 and the ratchet arm 6 are connected by a spring 8 for bringing them closer together,
Behind the lower arm 5b, the other end of the tension spring 9 having one end attached to a locking pin 9a provided on the main body 1 is locked so that the winding lever 5 can be pulled back to a predetermined rotation position. I have.

Next, the winding operation in the cover tape winding structure of the taping component supply device will be described.

In FIG. 1, a cover tape 14a on the surface of the tape 14 which is intermittently sent by a tape sending means (not shown).
Is peeled off by the tape pressing guide 10 at a position 11 before the predetermined component supply position.

The stripped cover tape 14a is wound on the take-up reel 2 as follows.

As shown in FIG. 2, the winding lever 5 is covered with a cover tape.
Driving in the direction of arrow A opposite to the winding direction of 14a, the ratchet pawl 7 is pushed by the projection 5c of the winding lever 5,
The ratchet arm 6 is rotated in the same direction. In this case,
The ratchet pawl 7 pressed by the projection 5c is pivoted about the pin 7a in the direction of arrow B to be released from the tooth 3a of the ratchet wheel 3, and the tip pawl 7b of the ratchet pawl 7 is moved to the tooth of the ratchet wheel 3. Move without touching 3a.

Next, when the driving of the winding lever 5 is released, the third
As shown in the drawing, the take-up lever 5 is rotated in the direction of arrow C by the tension spring 9 and the projection 5c is separated from the ratchet pawl 7, so that the ratchet pawl 7 is returned and rotated in the direction of arrow D by the urging force. The ratchet pawl 7 is engaged with the tooth portion 3a of the ratchet wheel 3, and the arm 6
Is rotated in the direction of arrow E by the spring 8, and the ratchet wheel 3 and the take-up reel 2 coaxial with the ratchet wheel 3 rotate in the take-up direction, and the cover tape 14a is taken up by the take-up reel 2. .

By repeating the above operation, the cover tape 14a is peeled off from the surface of the tape 14 intermittently conveyed, and the peeled cover tape 14a is further wound on the take-up reel 2.

Effect of the Invention According to the present invention, a taping component supply device having a cover tape winding structure, which is excellent in durability without wear of ratchet claws and teeth of a ratchet wheel and does not generate noise peculiar to a ratchet mechanism. Can be provided.
