A part transporting apparatus comprises: a guiding groove for lining up parts in one row and guiding the parts; a transporting member which is provided at the base of the guiding groove and transports the parts in a forward direction by itself moving forwards and backwards along the groove; and a driving means for reciprocally driving the transporting member in the forward and backward directions; wherein the transporting member is advanced slowly and retracted rapidly, so as to transport the parts forwards. Provided to this arrangement are: a stopper which operates so as to open and close in the width direction of the guiding groove, and hold the second part from the front of the row of parts being transported on the upper plane of the transporting member; and a shutter for opening and closing at the tip of the guiding groove, so as to cover the space above the first part in the row so as to prevent the part from flying out. The shutter is opened synchronously with the transporting member immediately before forward movement of the transporting member is completed, thereby extracting the first part separated from the second part. Such an arrangement provides for an apparatus for transporting parts, wherein the first part and second part can be separated in a sure manner even in the event that the parts are non-magnetic material, and wherein ease and stability of extracting of the first part is facilitated.

Apparatus for transporting parts

A feeder for chip components is provided wherein the chip components can be supplied with high stability even in high-speed operation by operating a conveying member at a lower speed than that of a chip mounter and operating the conveying member even when the chip mounter is stopped. The chip components on a belt are supplied in one direction by lowering a feed lever according to the input load from a chip mounter so as to drive the belt connected to the feed lever via a transmission mechanism intermittently in one direction. urging means is provided for urging the feed lever in the returning direction by storing the input load of the chip mounter as energy while an eddy current damper is provided for delaying the returning operation of the feed lever relative to the returning operation of the chip mounter. When the chip mounter operates downwardly, the feed lever is moved downwardly by linking to the chip mounter while the conveyor belt is maintained in a stationary state. When the chip mounter operates upwardly, the feed lever is moved upwardly so as to be delayed relative to the chip mounter by the eddy current damper while the belt is driven at a low speed.

Feeder for chip components

A feed lever is lowered, correspondingly to the load input of a chip mounter. A rotary drum is intermittently moved through a conversion mechanism, intermittently in one direction. Chip components placed in a component accommodation chamber are aligned and discharged. When a rotation resistance larger than a predetermined value acts, a belt is slid, and breaking of a chip component is prevented.

Feeding apparatus for chip component

A component carrying device has a simple constitution, and is capable of lining up components and carrying them in one direction with high reliability. The device comprises a guide groove for lining up components into one line and guiding them; a carrying member, provided on the bottom face of the guide groove, which can move forward and backward along the direction of the groove; and driving means, for driving the carrying member forward and backward at a higher speed when moving backward than when moving forward. The speed of the carrying member when moving forward is a speed at which a predetermined sustained frictional force acts between the carrying member and the components, which are mounted on the top face of the carrying member; and the speed of the carrying member when moving backward is a speed at which the frictional force between the carrying member and the components mounted on its top face, substantially breaks, so that the components are carried forward by the difference in frictional force.

A part-conveying apparatus allows parts to align and slide down a sloped chute without stacking therein. The part-conveying apparatus has a chute sloped to align and slide down parts, and a first mobile blade for slidably supporting the parts in a bottom section of the chute in the direction of the chute,. The lower end section of the chute is connected to a horizontal guide path, and a second conveying blade movable forward and backward is provided in a bottom section of the guide path. The second conveying blade reciprocates in a manner so as to move backward faster than to move forward, thereby conveying forward the parts placed thereon. A projection in the lower end of the first mobile blade engages with a groove of the second mobile blade so as to cause fine movements of the first conveying blade in the direction of the chute in synchronous with back and forth movements of the second conveying blade,. This allows the parts to side down.

Provided to this arrangement are: a second stopper which operates so as to open and close in the width direction of the guiding groove, and hold the second part from the front of the row of parts; and a movable first stopper which stops the first part at the tip of the guiding groove; wherein the first stopper is moved forwards synchronously with the transporting member immediately prior to completion of the forward movement of the transporting member, thereby separating the first part in the row from the second part. The first stopper retreats following the retreat of the transporting member. Such an arrangement provides for an apparatus for transporting parts, wherein the first part and second part can be separated in a sure manner even in the event that the parts are non-magnetic material, wherein ease of extracting of the first part is facilitated, and wherein parts can be supplied in a sure manner even in the event that an extracting failure occurs.

A part transfer apparatus includes a guide groove for aligning and guiding parts, a blade placed at the bottom of the guide groove so as to move forward and backward in the direction of the groove, and a driving device for reciprocally driving the blade so that the speed of backward movement of the blade is higher than the speed of forward movement. The part transfer apparatus conveys the parts forward by using the difference in frictional force. The driving device includes a cam, and a cam lever having a cam follower in contact with the peripheral surface of the cam. The rear end of the blade is in contact with the front side of the cam lever. Since the rotational motion of the cam is converted into the pivotal motion of the cam lever, and further into the reciprocating motion of the blade, vertical force hardly acts on the blade, and vertical vibration of the blade is inhibited. This makes it possible to prevent parts laid on the blade from being lifted and popped off, and to thereby stably transfer the parts.

A component feeder minimizes damage to chip components and efficiently discharges chip components aligned in a line. A bulk case is attached on the top portion of an external storage housing capable of being supplied with a large number of chip components. A predetermined number of the chip components is supplied at a time from the external storage housing to an inner housing of a component storage housing via a supplying path. The chip components in the inner housing enter into the outer housing from the reception inlet via a guide path by being scooped up by pockets in accordance with rotation of a rotary drum. The chip components are dropped into an aligning groove to be aligned and are discharged aligned in a line via a gate and a discharge path. The chip components slide down on the aligning groove to be discharged to a discharge path, via the gate, aligned in a line. Since excess components in the outer housing are returned to the inner housing via the return path by raking them up by a raking-up portion formed in the rotary drum, the number of chip components in the outer housing is small, resulting in maintaining increased alignment efficiency.

A component feeder is provided in which damage to chip components is minimized, being capable of efficiently discharging chip components aligned in a line. A bulk case is attached on the top portion of an outer storage housing capable of being supplied by a large number of chip components. Chip components are supplied from the outer storage housing to an inner housing of a component-storage housing via a supplying path. A predetermined number of the chip components in the inner housing is fed at a time to the outer housing via a communicating path in accordance with rotation of a rotary drum so as to be dropped into an aligning groove and aligned by a lug member of the rotary drum. The number of components in the outer housing is reduced, resulting in high efficiency of aligning and reduced damage to components. The chip components slide down on the aligning groove to be discharged to a discharge path, via the gate, aligned in a line.

A component conveying device is provided in which a lead component and a second component behind the lead component can be reliably separated and the lead component can be readily extracted with reduced error. The device includes a guide groove 6 for guiding and aligning the components P in a single line. A blade 5 is provided which moves back and forth in the groove. The components P are conveyed forward by moving the blade 5 forward at a low speed and then moving the blade backward in a high speed. A first stopper 31 holds a second component at the distal end of the device. A second stopper 41 stops the lead component P1 from moving back and forth, and a shutter 43 includes a magnet 49 for attracting the lead component. The second stopper is provided at a distal end portion of the guide groove 6. After the first stopper 31 holds the second component P2, the blade 5 moves forward by a predetermined distance, thereby conveying the lead component P1 forward with the blade 5 while the lead component P1 is attracted and held by the magnet 49 of the shutter 43. Thus, the lead component P1 is separated from the second component P2. Further, extraction of the lead component can be made easier by pulling the magnet 49 away from the lead component P1 just before the completion of the forward movement of the blade 5.
