Description

[Detailed Description of the Invention] The present invention is a method for disassembling wire parts into a parts feeder in which wire parts with lead wires, such as resistors and capacitors, are fed into the bowl of the parts feeder. This relates to a supply device.

Linear parts with lead wires such as resistors and capacitors as shown in Figure 1 A and B are lined up on a parts feeder and transported in sequence before being transported to painting or other finishing processes. However, before being fed into the bowl of the parts feeder, these parts are sent in a bundle that is intertwined with each other. However, the parts remained in a bundle without unraveling, making it impossible to transport them in an aligned manner using a parts feeder. Conventionally, the tangled parts were manually unraveled and fed into the bowl of the parts feeder little by little, which was inefficient and resulted in an increase in costs.

In view of these drawbacks, the present invention provides a receiving plate to which intertwined linear parts are supplied, and a number of guide needles for retaining and retaining the parts are provided on guides provided on both sides of the receiving plate to hang down and protrude. At the same time, the guide body is placed on the guide body, and the guide body is moved forward by the transfer mechanism, so that the parts are sequentially and integrally transferred to the falling part, and a diaphragm to which vibrations are applied by a vibrator is connected to the tip of the receiving plate. A device that allows the parts to fall while being loosened by vibration, and furthermore, below the falling position, needles are planted radially on the circumferential surface and a roller whose rotation is controlled at low speed is installed to perfect the loosening action. An embodiment of the present invention will be described below based on the drawings. 1 is a main body of a device for disassembling and supplying linear parts to a parts feeder according to the present invention. Linear parts 4, such as resistors and capacitors, are supplied between the rear parts of the side plates 3 and 3' of the frame 2, which has an open upper and lower surface.
A receiving plate 5 for receiving the receiving plate 4' is arranged horizontally, and both sides of the receiving plate 5 are raised to form guides 6, 6'.

Reference numeral 7 denotes a guide body movably placed on the guides 6, 6' facing above the receiving plate 5, and the guide body 7 includes a large number of guide pieces 8,
8'... are connected in series to connect the connecting member 9, such as tape or string.

The guide body 7 is moved forward by movement of the chains 16, 16' as the chains 16, 16' rotate. Note that the transfer means in the transfer mechanism 11 may be implemented by appropriate means such as a belt drive.

Reference numeral 19 denotes a diaphragm attached to the vibrator 20 attached to the lower part of the frame 2, and it is connected to the tip of the receiving plate 5 so as to be inclined slightly downward toward the falling part 21, and both ends are raised up. Guides 6'', 6 are formed to transition from the guides 6, 6', and a step 22 is formed between the guides 6'', 6 and the tip of the receiving plate 5.
has been established.

Reference numeral 23 denotes a roller having holding needles 24, 24'... radially implanted on its circumferential surface, and is pivoted via a rotating shaft 25 between the side plates 3 and 3' so as to be positioned opposite to each other below the falling part 21. It supports me. Furthermore, holding needle 2
The shape and arrangement of the parts 4, 24' can be selected as appropriate, such as a hook shape, depending on the shape and size of the parts 4, 4'.

26 is a drive unit, and a reducer 2 is installed in the front part of the side plate 3.
7, a sprocket 30 and a pulley 31 are attached to the drive shaft 29, a sprocket 32 corresponding to the sprocket 30 is attached to the end of the connecting shaft 15 in the transfer mechanism 11, and a sprocket 32 is connected between the sprockets 30 and 32. A pulley 3 corresponding to the pulley 31 is wound around the chain 33 and is attached to the end of the rotating shaft 25 of the roller 23.
A belt 35 is wound between the pulleys 31 and 34, and the rotation of the motor 28 controls the transfer mechanism 11 and the rollers 23 at low speed.

36, 36' are guide pieces, and guides 6'', 6
Inclined portions 37, 37' are formed in front of and opposite to each other to cause the guide body 7 to move from a position in front of the falling portion 21 in an upwardly inclined manner.

Next, to explain the operation of the device for disassembling and supplying linear parts to a parts feeder according to the present invention, the main body 1 is positioned by the support rod 40 so that the roller 23 is positioned above the bowl 39 of the parts feeder 38. Fix it. In such a state, the receiving plate 5
The bundle-shaped parts 4, 4'... are supplied onto the top, and then the guide body 7 is placed between the guides 6, 6', and the guide needles 10, 10'... of the guide body 7 move the receiving plate 5. The upper parts 4, 4'... are locked and held. When the motor 28 and vibrator 20 are activated by a signal from a detection switch that detects the amount of parts remaining in the bowl 39 of the parts feeder 38, the guide body 7 slowly moves forward in conjunction with the chains 16, 16' of the transfer mechanism 11. Then, the guide needles 10, 10'... move the parts 4, 4' forward integrally, and when the parts 4, 4'... reach the diaphragm 19, the vibrator 20 vibrates. The parts 4, 4', . . . , which are intertwined with each other due to the action, fall one after another from the end of the diaphragm 19 while being unraveled to some extent. Further, the holding needles 24, 24' are placed on a roller 23 provided below the falling portion 21 and held in place by the holding needles 24, 24', and as the roller 23 rotates at a low speed, the holding needles 24, 24' . . . They slip through the gaps one by one little by little, are unraveled into the bowl 39 of the parts feeder 38, and are then dropped and supplied.

Also, in the process of transferring the parts 4, 4'... by the guide body 7, the parts 4, 4'... are loosened by the step 22 when moving from the receiving plate 5 to the diaphragm 19, and the parts 4, 4'... As shown in FIG. 5, the guide body 7 is inclined upwardly from the position in front of the falling part 21 along the inclined parts 37, 37' of the guide pieces 36, 36' of the guide body 7. Guide pieces 8, 8'...
As the... are bent, the guide needles 10, 10'...
Since the parts 4, 4', . . . are expanded and act to separate the entangled parts, the unraveling action of the parts 4, 4', . . . is further promoted.

In short, the present invention arranges a receiving plate 5 to which linear parts 4, 4' are supplied, and guides 6, 6' provided on both sides of the receiving plate 5.
A large number of guide needles 10, which lock and hold 4'...
Since the guide body 7 having the guide bodies 10' hanging downwardly protruded is placed thereon, and the conveying mechanism 11 for forwardly conveying the guide body 7 is associated with the guide body 7, the parts 4, which are supplied on the receiving plate 5, 4'... and the guide needles 10, 10'...
... can be held and transferred integrally and sequentially, and since a diaphragm 19 to which vibration is applied by a vibrator 20 is connected to the tip of the receiving plate 5, the vibration action on the diaphragm 19 The parts 4, 4'... can be unraveled, and the retaining needle 2 is attached to the peripheral surface below the falling part 21 at the tip of the diaphragm 19.
4, 24', . The falling parts 4, 4'... are moved to roller 2.
The holding needles 24, 24' are held by the holding needles 24, 24' of No. 3, and the holding needles 24, 24'
By passing the parts 4, 4'... through the parts 4, 4'..., it is possible to further understand them.

Further, the guide body 7 has a bendable structure in which a large number of guide pieces 8, 8', . . . are provided, so that the guide needles 10, 10', .
The separation and disassembly action of the parts 4, 4', etc. can be promoted by the expansion of the parts 4, 4', etc., and since the step 22 is provided between the receiving plate 5 and the diaphragm 19, the parts 4, 4',... When transferred from the receiving plate 5 to the diaphragm 19, the parts 4,
4'... can be brought into play.

Therefore, according to the present invention, it is possible to mechanically drop and feed the parts 4, 4'... into the bowl 39 of the parts feeder 38 while reliably disentangling the parts 4, 4', etc., which are supplied in an intertwined state. The practical effects of this, such as being able to ensure alignment and conveyance at the feeder 38, are tremendous.
