Abstract

A workpiece transporter can avoid contact between workpieces, and can smoothly and stably transport the workpieces to a downstream side. The transporter (1) of workpieces (2) has a conveyor (3) for loading and placing the workpieces, and multiple swing bodies (4) are arranged above the conveyor and extend in the transport direction. The swing bodies respectively have upstream side arms (42) and downstream side arms (43), wherein the upstream side arms are parallel to the conveyor, take a shaft portion (61) which extends in a direction of forming a right angle relative to the transport direction as the center of rotation, and extend toward the upstream side; the downstream side arms rotate by taking the shaft portion (61) as the center and are heavier than the upstream side arms. In a state that the workpieces are not in contact with both the upstream side arms and the downstream side arms, a gap (h1) between the upstream side arms and the conveyor is larger than the height of a workpiece. In a state that the workpieces are configured to be on a lower side of the downstream side arms and the workpieces are in contact with the downstream side arms, the gap (h3) between the upstream side arms and the conveyor is smaller than the height of a workpiece.

The specific embodiment

Below, with reference to the description of drawings embodiments of the present invention.

Fig. 1 and Fig. 2 represent that the integral body of the Work transfer apparatus 1 of embodiment of the present invention constitutes.Handling device 1 is with workpiece 2(gear for example) the i.e. right side carrying among the figure of side downstream, by the conveyer 3 of mounting workpiece 2, arrange a plurality of pendular bodies 4 of arranging with the carrying direction of workpiece 2 above the conveyer 3, be located at a plurality of pendular bodies 4 above and the tabular rotational stop 5(of the amount of spin of restriction pendular body 4 for ease of explanation, in Fig. 1, be illustrated by the broken lines.), swing supports the pendular body support 6 of pendular body 4 freely, the workpiece retainer 7 that is disposed at the downstream of conveyer 3 constitutes.

Conveyer 3 by a plurality of rollers 31 and be wound in sheet on a plurality of rollers 31 be with 32 to constitute.At least one of a plurality of rollers 31 is the driven roller that is connected with electrical motor.When driven roller is driven by electrical motor, be with 32 side shiftings downstream, thus, with the workpiece 2 downstream side carrying of mounting on 32.

Pendular body 4 equally spaced disposes in the carrying direction of workpiece 2.Pendular body 4 possesses cylindrical body 41, from the cylindrical body 41 upstream side arm 42 that upstream direction is extended under the skew back, from the cylindrical body 41 downstream side arm 43 that direction is extended under the skew back downstream.Cylindrical body 41 is outer be embedded in from pendular body support 6 with respect to conveyer 3 axial region 61 parallel and that extend with respect to the carrying direction with meeting at right angles, thus, pendular body 4 can freely be swung centered by axial region 61 and cylindrical body 41.

Upstream side arm 42 is the arm of T word shape roughly.Upstream side arm 42 possesses the arm base portion 42a that is connected with cylindrical body 41, the workpiece abutting part 42b that extends to downside from the approximate right angle ground, end of arm base portion 42a, the retainer abutting part 42c from extending to the opposite sense of workpiece abutting part 42b with the end.

Downstream side arm 43 is the arm of rectilinear form.Downstream side arm 43 possesses arm base portion 43a and is installed on the 43b of hammer portion of arm base portion 43a.Downstream side arm 43 is owing to possess the 43b of hammer portion, thereby than upstream side arm 42 weights.

Upstream side arm 42 and downstream side arm 43 all not with workpiece 2 state of contact under, weight balancing by upstream side arm 42 and downstream side arm 43, pendular body 4 clockwise rotates in figure, and the retainer abutting part 42c of upstream side arm 42 contacts with rotational stop 5 and stops (state of the pendular body 4 on the left of Fig. 2).Under this state, between workpiece abutting part 42b and conveyer 3, form the gap h1 bigger than the height of workpiece 2, workpiece 2 can be by the downside of upstream side arm 42.

Relative with it, the gap h2 between downstream side arm 43 and the conveyer 3 is littler than the height of workpiece 2.Therefore, when the downside of workpiece 2 by upstream side arm 42 moved to the downside of downstream side arm 43, workpiece 2 contacted with downstream side arm 43.And when workpiece 2 further downstream during side shifting, downstream side arm 43 jumps to the top, rotates counterclockwise in figure.

Under the state of the pendular body 4 on Fig. 2 central authorities that downstream side arm 43 takeoffs and right side, between downstream side arm 43 and conveyer 3, form the gap that equates with the height of workpiece 2, workpiece 2 can pass through the downside of downstream side arm 43.Workpiece 2 is by during the downside of downstream side arm 43, downstream side arm 43 with slip above the workpiece 2, the weight by the 43b of hammer portion is close to workpiece 2 and conveyer 3, makes the stable posture of workpiece 2.

In addition, the gap h3 between upstream side arm 42 and the conveyer 3 is littler than the height of workpiece 2.Thus, stop other workpiece 2 side shifting downstream be positioned at upstream side, avoid workpiece 2 to contact with each other.

Further movement or workpiece 2 are taken out of from conveyer 3 downstream by workpiece 2, when downstream side arm 43 and contacting of workpiece 2 become when not contacting, by the weight balancing of upstream side arm 42 and downstream side arm 43, pendular body 4 clockwise rotates in figure, becomes the state of the pendular body 4 in Fig. 2 left side again.

Fig. 3 A～Fig. 3 E represents a series of action of above-mentioned Work transfer apparatus 1.Further specify the action of above-mentioned Work transfer apparatus 1 with reference to it.In addition, in the following description, for ease of explanation, a plurality of pendular bodies 4 are called the first pendular body 4a, the second pendular body 4b, the 3rd pendular body 4c successively from the downstream, a plurality of workpiece 2 that are disposed on the conveyer 3 are called the first workpiece 2a, the second workpiece 2b, the 3rd workpiece 2c, the 4th workpiece 2d successively from the downstream.

Fig. 3 A is illustrated in the downside configuration workpiece 2a～2c of the downstream side arm 43 of each pendular body 4a～4c, and workpiece 2a～2c contacts with the upstream side arm 42 of the workpiece retainer 7 that is positioned at these downstreams or

pendular body

4a, 4b and the state that stops.

When the first workpiece 2a that will be positioned at downstream from this state took out of from conveyer 3, the first pendular body 4a was around clockwise rotating, the downside (Fig. 3 B) of the upstream side arm 42 that the second workpiece 2b can be by the first pendular body 4a.

So the second workpiece 2b is by the downside of the upstream side arm 42 of the first pendular body 4a, the downstream side arm 43 of skipping the first pendular body 4a is further mobile downstream.In addition, because the downstream side arm 43 of the second workpiece 2b and the second pendular body 4b does not contact, therefore, the second pendular body 4b is around clockwise rotating, and the 3rd workpiece 2c can pass through the downside (Fig. 3 C) of the upstream side arm 42 of the second pendular body 4b.

The second workpiece 2b and the 3rd workpiece 2c contact with the upstream side arm 42 of workpiece retainer 7 and the first pendular body 4a respectively afterwards and stop, and the 4th workpiece 2d is by the upstream side arm 42 of the 3rd pendular body 4c and the downside (Fig. 3 D) of downstream side arm 43.

Afterwards, the 4th workpiece 2d contacts with the upstream side arm 42 of the second pendular body 4b and stops, and become the state of Fig. 3 E, but this state is identical with the state shown in Fig. 3 A.

Therefore, when the workpiece 2 that at every turn will be disposed at downstream is taken out of from conveyer 3, carry out the action of Fig. 3 A～Fig. 3 E, avoid workpiece 2 to contact with each other, simultaneously, workpiece 2 one by one is transported to the downstream.Workpiece 2 is whole below it to be contacted with conveyer 3, and its result is can be with workpiece 2 smooth and easy and be transported to downstream (with the first aspect present invention corresponding effect) with stable posture.

And when passing through the downside of downstream side arm 43, downstream side arm 43 slips with workpiece 2, and workpiece 2 and conveyer 3 are close to.Thus, can make the posture of workpiece 2 more stable (with the second aspect present invention corresponding effect).

In addition, the size with each workpiece 2 among the figure is made as identical size, but according to the part Handling device 1 of above-mentioned formation, can carry the workpiece 2 of all size in the scope of the above-mentioned action that does not limit pendular body 4.

Embodiments of the present invention more than have been described, but above-mentioned embodiment only being represented the part of application examples of the present invention, is not the particular content that technical scope of the present invention is defined as above-mentioned embodiment.

For example, constitute rotational stop 5 by the tabular parts of the top that is disposed at a plurality of pendular bodies 4, but also can be constituted by the pin-shaped or block parts that contact with the arm base portion 42a of upstream side arm 42.Perhaps also can contact the rotation of restriction pendular body 4 by making downstream side arm 43 with conveyer 3.

In addition, constitute the carrying road of workpiece 2 by conveyer 3, but the roller that is disposed at the dip plane of also can serving as reasons constitutes and make workpiece 2 utilize its weight side mobile formation voluntarily downstream.
