Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a taped component, particularly a so-called axial electronic component having an axial lead such as a capacitor or a transistor. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding storage device for a taping component, which is useful for folding and storing a taping component in a folded state.

2. Description of the Related Art FIGS. 5 and 6 show a case of a taping component 55 in which a capacitor 51 is taped at its lead 52 with a tape-shaped mount 53 and an adhesive tape 54. FIG. The taping parts 55 are stored in a folded state as shown in FIG. 7 to facilitate subsequent handling.

Conventionally, in order to store such a taping part 55 in a folded state, a fold 56 is given to the taping part 55 in advance,
The taping component 55 is sent out to a folding storage conveyance path on the downstream side by a not-shown sandwiching conveyance roller, and is fed into the storage portion while being folded in a folded state at the fold portion so as to be stored. The folding uses a taping part 55 sent out from the nipping and conveying means in a meandering state according to a pre-made crease 56, and a corner portion to be folded is stored on the storage side by a rotating arm. To be stored in a predetermined folded state.

Problems to be Solved by the Invention However, since the folding storage transport path downstream of the nipping transport roller is formed in a gutter shape, the taping component received in the folded state is received from below,
And it only guides roughly from both sides. The rotating arm is sent out by the nipping and transporting roller, and only pushes the corner portion that is about to be broken along the fold to the storage side, so that the taping component is relatively free on the downstream side from the nipping and transporting roller. . For this reason, the folded state is in a storage state in which the folding is sweet and bulky, and the stability is poor, and the player wins. In addition, if the electronic component being taped is large and heavy, the taped component itself tends to fluctuate and fall easily, so it is difficult to store the electronic device in the conventional device in an orderly folded state. is there.

Means for Solving the Problems In order to achieve the above objects, the first invention of the present application is:
Preliminary folds are applied to the taping parts in which the loose parts are successively taped, and this taping part is sent out to the folding storage and conveyance path downstream thereof by the nipping and conveying means, and is folded into the crimped state at the fold portion to the storage section. In the folding storage device of a taping component to be fed and stored, the folding storage transport path has a length that can be overlapped on the front end side by a length substantially equal to the fold interval, facing from both sides in a direction perpendicular to the folding storage transport path. A pair of folding arms, rotatably pivotally supporting the folding arms at positions outside the overlapping length range, and taping each folding arm immediately after its tip is sent out from the nipping and conveying means. While pressing against the fold of the part, rotate it forward to the overlapping position, Rotation driving means for alternately rotating each folding arm back to the side retreat position where the pressing against the folding parts is released, and folding each folding arm prior to each folding arm being rotated backward Up and down drive means for moving the folding arm upward to a retracted position that deviates upward from the storage and conveyance path and moving the folding arm down to the storage and conveyance path after the return rotation.

According to a second aspect of the present invention, in the first aspect, a weight member for receiving a taping component pushed from the folding arm portion is provided in the folding storage transport path.

According to the above configuration of the first invention of the present application, when one of the pair of folding arms is reciprocated from the lateral retreat position to the overlapping position by the rotary driving means, the other folding arm is in the overlapping position. One fold portion of the taping component sent from the nipping and conveying means is largely eccentric from the normal feeding path of the nipping and conveying means to its leading end, and the downstream side from the fold is compressed toward the folding storage part. For this reason, the taping part is bent at an acute angle by the tip of the folding arm in the overlapping position, and the upstream side of the fold is appropriately stretched between the holding means and the downstream side between the folding part and the already stored portion. , The taping component is firmly supported by the fold at the tip of the folding arm at the overlapping position, and a stable state can be provided between the nipping and conveying means and the already stored portion.

Then, the folding arm to be folded presses the tip from the side to the next folding portion of the taping component in a state of being stretched between the tip of the folding arm at the overlapping position and the holding and conveying means. As a result, the taping component is eccentric from the normal delivery path of the nipping / conveying means so that the next fold is on the side opposite to the previous fold, and the next fold is opposite to the previous fold. While maintaining or increasing the tension in the direction of, it is bent more. When the folding arm reaches the overlapping position with the folding arm already at the previous overlapping position by being swung, the gap between the next fold and the previous fold is sandwiched between both arms, so that the tip of the taping component is The fold can be folded into two folds, and the next fold can hold the taping component by the firm support at the next fold, as in the case of the fold arm at the previous overlapping position, and the holding and conveying means and the existing fold. A stable state can be obtained between the storage sections.

Next, the folding arm, which was in the overlapping position first, is moved upward to the upper retreat position by the vertical movement means, and is retracted upward from the taping component that has been folded in two at the previous fold. The folding arm at the upper retracted position is further returned to the side retracted position by the rotation driving means while being separated from the taping component and the folding arm at the next overlapping position while remaining at the upper retracted position. After being moved down to the folding storage conveyance path by the vertical movement driving means at the return position, the folding device is subjected to the folding operation at the next fold portion of the taping component, so that each folding arm can alternately work with the taping component. Taping parts sent out from the holding and conveying means can be repeated,
It can be stored while folded in a folded state along a fold portion that has been formed in advance.

According to the above configuration of the second invention of the present application, since the taping component in the folded state which is pushed into the folding storage transport path by the folding arm is received by the weight member provided on the folding storage transport path, the folded state is obtained. The taping component is pressed against the weight member and is compressed and held. As the folded portion of the taping component is increased, the weight member can be maintained in the compressed and held state while being pushed backward on the folding storage transport path.

Embodiment A description will be given of a taping device to which a folding storage device for a taping component as one embodiment of the present invention shown in FIGS. 1 to 4 is applied.

FIG. 4 shows the entire taping device as viewed from above.

Axial electronic components such as the condenser 51 are independently supplied in the direction of arrow a by the parts feeder 2 provided at the left end on the main body base 1. This electronic component 51 is the main body base 1
It is conveyed toward the turntable 3 located in the upper center,
It is sequentially escaped to the turntable 3 at the position P11 around the turntable 3. The escaped electronic component 51 is carried by the turntable 3 in the direction of arrow b, and the height of the product is inspected at the position P12. At the next position P13, the leads 52 of the electronic component 51 are extended by the ironing method. Thereafter, at the position P14, the lead is formed into a predetermined shape. At the position P15, the lead 52 is cut to a predetermined length. At the position P16, the electronic components determined to be defective from the inspection result are excluded. At the position P17, the leads 52 of the electronic components 51 sequentially carried by the turntable 3 are transferred to the tape-shaped mount 53 and the adhesive tape 5 fed to the position P17.
Taping is performed as shown in FIG.

In the position P19, the distance between the lead wires of each electronic component is regulated, and in the next position P20, the pitch hole 57 for feeding is set.
(FIGS. 5 to 7) are completed. A fold 56 is formed at position P21, and a taping part 51 is formed at position P22.
Is finally sent out to the folding storage section 10 by the nipping and conveying roller 9 and stored in a folded state.

As shown in FIG. 1 to FIG.
A folding storage transport path 11 is provided downstream of the nipping transport roller 9. The folding storage transport path 11 has a gutter shape as shown in FIGS. 1 to 3, and has guide walls 12 on both sides. A pair of folding arms 13 and 14 are provided on both sides in the middle of the folding storage transport path 11. Each folding arm
13 and 14 are supported on both sides of the folding storage transport path 11 by a shaft 17 on a slider 16 movably guided by a guide rail 15 in a direction parallel to the folding storage transport path 11 so as to be rotatable and vertically movable. A rotary drive cylinder 19 is connected to a shaft 17 of one of the folding arms 13 via an arm 18, and a vertical drive cylinder 20 is concentrically connected. A rotary drive cylinder 22 is connected to a shaft 17 of the other folding arm 14 via an arm 21, and a vertical drive cylinder 23 is concentrically connected.

Further, the sliders 16 are connected by shafts 33 and 34 to respective ends of a front / rear switching lever 32 pivotally supported at the center by a shaft 31. A swing drive cylinder 35 is connected to a part of the lever 32.

When the folding arms 13 and 14 rotate around the shaft 17, the overlapping length range L when the folding arms 13 and 14 reach the position orthogonal to the folding storage conveyance path 11 becomes the fold interval S of the taping component 36. They have lengths that are almost equal.

A weight box 41 is placed downstream of the installation position of the folding arms 13 and 14 of the folding storage transport path 11.

 The operation will be described below.

The taping component 55 taped by the apparatus shown in FIG.
Sent to 11 As shown in FIGS. 1 and 2, when one of the folding arms 14 is swung in the direction of arrow c from the lateral retreat position toward the overlapping position by the rotary drive cylinder 22, the other folding arm 13 becomes The one fold 56 of the taping component 55 which is already at the overlapping position and is sent out from the nipping / conveying roller 9 is moved from the normal feeding path of the nipping / conveying roller 9 to its own tip side, that is, the second
While being largely eccentric to the lower side in the figure, the downstream side from the fold 56 is compressed toward the folding storage unit 10. For this reason, the taping part 55 is provided with the folding arm in the overlapping position.
13 is bent at an acute angle at the fold 56 so that the upstream side of the fold 56 is appropriately stretched between the nipping and conveying roller 9 and the downstream side is the weight box 41.
And is held in a folded state by being compressed and held between the already-stored portion that is pressed. As a result, the taping component 55 is firmly supported at the tip of the folding arm 13 at the fold 56, and a stable state can be maintained between the nipping and conveying roller 9 and the already stored portion.

The folding arm 14 to be moved is moved between the tip of the folding arm 13 at the overlapping position and the nipping conveyance roller 9.
Next fold of taping part 55 stretched between
The tip is pressed from the side to the portion 56 as shown in FIGS. As a result, the taping part 55 becomes the next fold 56
The part is decentered from the normal delivery path of the nipping and conveying roller 9 on the side in the direction opposite to the above-mentioned fold part,
At the next fold 56, the fold is further bent in the opposite direction to the previous fold 56 while increasing the tension.

It should be noted that the tension state can be increased when the tip end rotation speed of the folding arm 14 is higher than the feeding speed of the nipping / conveying roller 9. However, if the tension state is maintained to the extent that the taping component 55 can be prevented from falling down. Well, there is no need to strengthen as described above.

When the folding arm 14 to be swung reaches the overlapping position with the folding arm 13 at the previous overlapping position, the two folding arms 1 pass between the next fold 56 and the previous fold 56.
The leading fold 56 of the taping component 55 can be folded in two so as to be sandwiched between 3 and 14 (the imaginary line in FIG. 2). The next fold 56 is to stabilize the taping component 9 between the nipping and conveying roller 9 and the already stored portion by firmly supporting the fold 56 as in the case of the folding arm 14 located at the above-mentioned overlapping position. Can be.

Next, the folding arm 13 previously at the overlapping position is moved up to the upper retreat position by the vertical movement driving cylinder 20,
Taping parts 55 folded in two at the previous fold 56
Is evacuated upward. At this time, the swing drive cylinder 35 rotates the front / rear switching lever 32 clockwise in FIG. 2 to move the folding arm 13 to the upstream side and the folding arm 14 to the downstream side. For this reason, since the front-back positional relationship of each folding arm 13 and 14 is reversed,
The portion of the taping part 55 folded by the folding arm 14 is further compressed into the stored portion, and the folding arm 13 is located on the upstream side of the folding arm 14 to enable the folding operation at the next fold 56 part. .

Here, the folding arm 13 is returned to the lateral retreat position in a state where the folding drive arm 19 is disengaged upward from the taping component 55 and the folding arm 14 that has become the next overlapping position while remaining in the upper retreat position, and After being moved down by the vertical drive cylinder 20 at this return position, the taping component 55 is subjected to a folding operation at the next next fold 56.

By the above, the folding arms 13 and 14 can be repeatedly operated so as to alternately fold the taping component 55, and the taping component 55 sent out from the nipping and conveying roller 9 is moved along the fold 56 previously applied thereto. It can be folded and stored in a folded state.

According to the first aspect of the present invention, when one of the pair of folding arms is pivoted from the lateral retreat position to the overlapping position by the rotation driving means, the other folding arm is in the overlapping position and is pinched. One fold portion of the taping component sent from the conveying means is largely eccentric from the normal feeding path of the nipping and conveying means to its own tip side, and the downstream side from the fold is compressed toward the folding storage portion, and this compression is performed. Therefore, the taping component is bent at an acute angle by the tip of the folding arm at the overlapping position, the upstream side of the fold is appropriately stretched between the holding means, and the downstream side is between the already stored portion. The folding part is maintained in a folded state, so the taping parts are firmly supported by the fold at the tip of the folding arm at the overlapping position It is possible to stabilize between the nipping and conveying means and the already stored part, and even if the taping component is unstable such as taping a large electronic component, it may fall down or fluctuate. It can be handled without making it possible to reliably achieve folding at one fold.

The folding arm to be folded is pressed from the side to the next folding portion of the taping component in a state of being stretched between the tip of the folding arm at the overlapping position and the holding and conveying means. Taping part, the next fold is on the side opposite to the previous fold,
The fold is decentered from the normal delivery path of the holding and conveying means, and is gradually bent while maintaining or strengthening the tension state in the direction opposite to the previous fold at the next fold, and the fold is swung. When the arm reaches the overlapping position with the folding arm already at the previous overlapping position, the leading folding portion of the taping component is folded in half so that the next folding line and the preceding folding line are sandwiched between both arms. The next fold can be folded into a state, and the taping part can be stably supported between the nipping and conveying means and the already stored portion by the firm support at the next fold as in the case of the folding arm at the previous overlapping position. Since it can be in a state, the folding of the taping part at the next fold can be handled without falling or swinging the taping part as before. It can be reliably performed following the folding in the crease.

And the folding arm which was in the overlapping position first is moved up to the upper retreat position by the vertical moving means, retreated upward from the taping part which was folded in two at the previous fold, and the folding arm which became the upper retreat position is Further, it is returned to the side retreat position by the rotation driving means in a state where the taping component and the folding arm which has become the next overlapping position remain in the upper retreat position and are moved back to the side retreat position. After being moved down to the folding storage transport path by the above, the taping component is subjected to the folding operation at the next fold portion, so that the folding arms are alternately operated on the taping component as described above to repeatedly perform folding. The taping part continuously fed from the nipping and conveying means can be folded along the fold line previously formed on the taping part. It is possible to bulk low securely housed while folding in the state.

According to the second invention of the present application, the taping component in the folded state, which is pushed into the folding storage transport path by the folding arm, is received by the weight member installed on the folding storage transport path, whereby the folded taping component is received. Is pressed and held by this weight member, and the weight member can maintain the above-mentioned compression holding state while being pushed and moved backward on the folding storage transport path along with the increase of the folded portion of the taping component. Folding of the stored taping parts can be achieved even lower, making the taping parts more convenient for subsequent handling and use.
