Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base material conveying device for intermittently conveying a long base material in the longitudinal direction and periodically positioning and holding it.

[0002]

2. Description of the Related Art At present, a roller conveyor or the like is used to form a base material transfer device for sequentially transferring and holding a long base material such as a hoop material, and a press machine or the like is provided at a side edge portion of such a base material transfer device. Processing systems in which a plurality of types of processing devices are sequentially arranged have been implemented. In such a processing system, a plurality of processing devices sequentially carry out predetermined machining on a long base material which is intermittently conveyed by the base material conveying device and is regularly positioned and held, whereby a small piece shape is formed. Mass-produced processed products.

[0003]

In the processing system as described above, a long base material is intermittently transferred by a base material transfer device and periodically positioned and held, so that the long base material is sequentially processed by a plurality of types of processing devices. The processing positions of the long base material are precisely matched.

However, a base material conveying device such as a roller conveyor requires a mechanism for stopping and positioning and holding a long base material conveyed by rollers at a predetermined position.
Although the recess formed in the long base material by the primary processing is made to collide with the movable gate, colliding the member in this manner is not preferable because it induces noise and vibration.

For example, as a base material conveying device that does not have such a problem, suction cups are provided at both ends of a long slider that reciprocates in the longitudinal direction of a long base material, and these suction cups make a long material. Although there is a device that sucks and holds a substrate and conveys it, this is less versatile because the position at which the suction cup holds the long substrate cannot be changed. In other words, since the through holes are continuously formed in the primary processed long base material and the like, the suction cup needs to hold the long base material at a position where it does not interfere with the through hole. When the product is changed, the position and shape of the through hole may change, so that the suction cup may not be able to properly hold the long base material.

Further, the above-mentioned base material conveying device in which the roller conveyor and the gate are combined requires a dedicated drive source for the rotational driving of the roller and the opening / closing driving of the gate. Even in the transfer device, since it is necessary to provide a dedicated drive source for each of the suction drive and the reciprocating drive of the suction cup, these base material transfer devices have a complicated structure and it is difficult to reduce their size and weight.

[0007]

In a base material conveying device for intermittently conveying a long base material in the longitudinal direction and periodically positioning and holding the long base material, a long slider arranged parallel to the long base material is used. A reciprocating mechanism that slidably supports in the longitudinal direction and that reciprocally drives this slidable long slider is connected to one drive source, and the long base material is connected to this drive source by a flexible power transmission mechanism. A plurality of base material holding mechanisms that are releasably held at a plurality of positions are provided, and these base material holding mechanisms are movably positioned and held in the longitudinal direction of the long base material and integrally connected to the long slider. A slider connection mechanism is provided.

[0008]

Since the holding operation of the base material holding mechanism and the reciprocating operation of the long slider are executed by one driving source, it is possible to contribute to size reduction and weight reduction and productivity improvement. For example, to change the product to be manufactured. Even if the space between the base material holding mechanisms is adjusted, the position of the base material holding mechanism can be adjusted easily because it is movable on the long slider, and the base material holding mechanism connected to the drive source by the flexible power transmission mechanism is Since there is no concern that an operation timing error will occur even if it is moved, its versatility is extremely good and it can be applied to the production of various products.

In the carrying unit 31, as shown in FIG. 5, a support pin 35, which is a base material holding mechanism, is vertically movable on a slider 34 slidably supported by guide rails 33 in the longitudinal direction. The rear end of the rotating arm 36, whose front end contacts the support pin 35 from below, is pressed upward by a spring 37. Further, an inner wire 39 of a drive wire 38, which is a flexible power transmission mechanism, is connected from below to the rear end of the rotary arm 36 biased upward by the spring 37.

Is attached to the outer holder 48, and the drive wire 3 is attached to a flat plate-shaped inner holder 49 located on the outer holder 48.
8, 45 inner wires 39, 46 are attached. Here, the inner holder 49 is a guide rail.
It is supported slidably in the vertical direction (not shown) or the like, and is pressed upward by a spring (not shown). The disc cam 26 protruding from the gear box 22 is positioned and held by contacting the disc cam 26 from below. ing.

By doing so, in the continuous machining apparatus 1, the press sections 9 and 10 each performing a predetermined operation.
The caulking machine 19, the transport unit 31, and the holding unit 32 are connected to one drive motor 3 by various mechanisms such as the gear train 6 and the spline shafts 12 and 13.

As shown in FIG. 4, the continuous processing apparatus 1 illustrated in this embodiment has a hoop material 52 in which a large rectangular hole 50 and a small diameter circular hole 51 are continuously formed by primary processing. Is used as a long base material, and the hoop material 52 is sequentially transported forward by the transport unit 31 and various processes are continuously performed by the press parts 9 and 10 and the crimping machine 19 or the like to form a small electrode plate. 53 is mass produced. In the continuous processing apparatus 1, each of the two transport units 31 that holds the hoop material 52 at two places is detachably attached to the main body housing 2 to remove the hoop material 52.
The hoop member 52 is movable in the longitudinal direction of the
Since the support pin 35 of the transfer unit 31 is connected to the connecting arm 41 that is movable on the slide shaft 27 parallel to the position, the position of the support pin 35 that holds and transfers the hoop member 52 is adjustable. ing. By doing so, in the continuous processing device 1, the base material conveying device in which the holding interval of the hoop material 52 is variable includes the drive motor 3, the gear box 22, the disc cams 25, 26, and
The slide shaft 27, the transport unit 31, the drive wire 38, the connecting arm 41 and the like are formed. In this continuous processing device 1, the hoop material 5 is
Since the longitudinal direction of 2 is parallel to the longitudinal direction of the spline shafts 12 and 13, the caulking machine 1 movably connected to the spline shafts 12 and 13 is movable.
9 is also movable in the longitudinal direction of the hoop member 52.

With such a structure, the operation of each part when the continuous machining apparatus 1 manufactures the electrode plate 53 from the hoop material 52 will be described in detail below. First, in the continuous machining device 1, the drive motor 3 rotationally drives the flywheel 5 via the belt drive device 4 to stably generate a high-torque driving force. The two press parts 9 and 10 are transmitted by being transmitted to the shaft 7.
On the other hand, the driving force of the main shaft 7 is transmitted to the spline shaft 12 by the gear train 11, and the driving force of the spline shaft 12 is transmitted by the bevel gear 16 to the interlocking shafts 14, 1.
5 and the spline shaft 13 are sequentially transmitted to drive the two drive bases 17 and 18. Further, in the continuous machining apparatus 1 exemplified here, the caulking machine 19 is connected to the one drive base 17, so that the caulking machine 19 and the two press parts 9 and 10 perform machining operations accurately synchronized with each other. It will be.

On the other hand, in the continuous machining apparatus 1, since the driving force of the interlocking shaft 15 as described above is transmitted to the two disc cams 25 and 26 by the gear box 22, the rotation of the disc cam 25 causes the slide shaft to rotate. 27 and the slider 34 of the two transport units 31 reciprocate in the front-rear direction at a predetermined timing. On the other hand, when the disc cam 26 rotates, the inner holder 49 reciprocates in the vertical direction at a predetermined timing, so that the inner wires 39, 46 of the drive wires 38, 45 connected to the inner holder 49 move in the outer wires 40, 47. By slidingly moving, the support pins 35 of the two transport units 31 and the holding unit 3
The two slide arms 43 simultaneously reciprocate in the vertical direction.

That is, in this continuous machining apparatus 1, the driving force of one drive motor 3 is held by the press units 9 and 10, the caulking machine 19 and the carrying unit 31 by various mechanisms such as the gear train 6 and the spline shafts 12 and 13. Since it is mechanically transmitted to the unit 32, the electrode plate 53 can be accurately mass-produced while the conveying operation and the processing operation of the hoop material 52 are precisely synchronized.

Therefore, the hoop material 52 formed by the carrying unit 31 and the holding unit 32 of the continuous processing apparatus 1 as described above.
The transport operation of will be described in detail below. First, in the continuous processing apparatus 1, the carrying unit 31 is adapted to carry the positioning and holding of the hoop material 52 by fitting the support pin 35 into the round hole 51, and start such carrying. In this case, the slider 3 located at the rearmost part of the transport unit 31
4, the support pin 35 rises and the hoop member 52 has a round hole 51.
, And at the same time, the slide arm 43 of the holding unit 32 also rises to release the holding of the hoop material 52. Therefore, in this state, the slider 34 of the transport unit 31 advances and stops to transport and hold the hoop material 52. Therefore, two presses are performed on the hoop material 52 thus positioned and held. The parts 9 and 10 and the crimping machine 19 execute a machining operation described later. And
When such a processing operation is completed, the slide arm 43 of the holding unit 32 lowers and holds the hoop material 52, and at the same time, the support pin 35 of the transport unit 31 lowers and separates from the round hole 51 of the hoop material 52. As the slider 34 of the transport unit 31 retracts, the hoop members 52 do not retract and the respective parts return to the initial state.

In the base material conveying device of the continuous processing device 1, since the vertical movement and the reciprocating movement of the support pin 35 as described above are realized by one drive motor 3, it contributes to downsizing and weight reduction and productivity improvement. It is supposed to do. Further, in the base material transfer device of the continuous processing device 1 described above, for example, the interval between the round holes 51 may change when the product to be manufactured is changed.
1 can be easily dealt with by adjusting the positions of the connecting arm 41 and the support pin 35 and the like are connected to the gear box 22 by the flexible drive wire 38 even if the position of the transport unit 31 is moved. Therefore, there is no concern that an error will occur in the operation timing. In the base material transfer device of the continuous processing device 1, the disc cam 2 determines the transfer stroke of the hoop material 52 and the timing of positioning and holding.
Since the disc cams 25 and 26 can be freely exchanged, various forms of conveyance can be realized.

Next, the content of the continuous processing performed by the continuous processing apparatus 1 on the hoop material 52 conveyed as described above will be described based on FIG. 6 with reference to FIG. Here, a cutting die and a bending die (both not shown) are set in parallel in the first press portion 9, and the second press portion 10 is provided.
A cutting die is set in. First, as illustrated in FIG. 6A, in the hoop material 52, a rectangular hole 50 and a round hole 51 are continuously provided by primary processing, and as shown in FIG. The cutting die of the press portion 9 cuts the right edge portion of the hoop material 52 and shapes it into a comb tooth shape, and as shown in FIG. The projecting portion 54 is bent into a crank shape. Therefore, as illustrated in FIG. 3D, the protruding portion 5 of the hoop member 52 is
The caulking machine 19 is connected to the terminal 55 in the round hole 51 located at the tip of
Hoop material 5 with this terminal 55 attached
When the cutting die of the second press portion 9 cuts the left edge portion of No. 2, small-piece electrode plates 53 are mass-produced as illustrated in FIG. The pressing sections 9 and 10 and the crimping machine 19 as described above are simultaneously operated, and the above-described processing is simultaneously performed every time the hoop material 52 is intermittently conveyed and positioned and held. It will be.

In other words, in the continuous processing apparatus 1, the base material transfer device for sequentially transferring the hoop material 52 and the processing mechanism are connected to one drive motor 3 and mechanically interlock with each other, so that the hoop material 52 is transferred. The electrode plate 53 is accurately mass-produced by precisely synchronizing the operation and the processing operation. Moreover, since each unit is driven by one drive motor 3 as described above, reduction in size and weight and power saving are realized as compared with a continuous machining system in which each unit has a dedicated drive motor.

Here, in the continuous processing apparatus 1, as described above, since the conveyance and processing of the long base material such as the hoop material 52 are synchronized with each other to accurately mass-produce the product, for example, the product to be manufactured is When changing, press parts 9 and 1 whose position is immovable
It may be necessary to adjust the front and rear positions of the moving processing unit 21 and the transport unit 31 with respect to zero. In this case, in the continuous machining device 1, the drive base 1 of the moving machining unit 21 is
7 and 18 are slidable in the front-rear direction on the spline shafts 12 and 13. Since the transport unit 31 is connected to the gear box 22 by the flexible drive wire 38 as described above, the position adjustment of these is possible. It is easy, and there is no concern that an error will occur in the operation timing even if it moves. Therefore, in the continuous processing apparatus 1, the positions of the moving processing unit 21 and the transfer unit 31 can be easily adjusted to accurately transfer and process the long base material.
Its versatility is extremely good and it can be applied to the production of various products.

In the base material conveying device of this embodiment, the drive wire 38 that transmits power by sliding the inner wire 39 inside the outer wire 40 is illustrated as a flexible power transmission mechanism. As a transmission mechanism, a flexible tube that transmits power by rotating the inner tube inside the outer tube
(Not shown) and the like are also possible. Further, in the base material conveying device of the present embodiment, the support pin 35 that fits into the round hole 51 of the hoop member 52 by moving up and down is illustrated as a base material holding mechanism that releasably holds the long base material. The invention is not limited to the above structure, and as such a substrate holding mechanism, for example, a magic hand (not shown) that holds a long substrate having no through hole can be implemented. Further, in the continuous processing apparatus 1 of the present embodiment, the metal hoop material 52, which has been subjected to the primary processing, is pressed or caulked to manufacture the electrode plate 53. It is not necessary to limit the form or material of the base material. Further, the front-back direction referred to in this embodiment is exemplarily defined based on the conveying direction of the hoop material 52 in order to simplify the description, and this limits the actual use direction of the continuous processing apparatus 1 and the like. Not something to do.
