Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting rod aligning and conveying apparatus for transferring a rod and a cap of a connecting rod from a first conveying apparatus including a walking beam to a second conveying apparatus in an aligned state.

[0002]

2. Description of the Related Art Normally, an engine connecting rod is composed of a rod and a cap which are divided into two parts at a large end. When such a connecting rod is conveyed by a walking beam, a pair of rods and a cap are laterally aligned and simultaneously conveyed by a plurality of rows of walking beams having the same drive source.

[0003]

By the way, when the rod of the connecting rod is conveyed by a walking beam, the rod is conveyed in an inclined posture in which the longitudinal direction of the rod is substantially vertical and the upper end is biased forward in the conveying direction. . On the other hand, since the connecting rod caps are transported in a normal posture without inclination, the length in the front-rear direction of the predetermined number of rods aligned on the walking beam is longer than the length in the front-rear direction of the same number of caps. I will end up. For this reason, when the same number of rods and caps forming a pair are collectively transferred from the walking beam to another transfer device, the transfer work is difficult due to the fact that the rods have an inclined attitude. There is a problem.

The present invention has been made in view of the above circumstances, and an aligning and conveying apparatus for connecting rods capable of reliably transferring the same number of rods and caps forming a pair from a walking beam to another conveying apparatus. The purpose is to provide.

It is supported on the upper surface of the column 4 via a column 15. Therefore, by driving the cylinder 12 to extend, each of the eight rods R supported at the front end of the three rows of rod carrying walking beams 1 and the three rows of cap carrying walking beams 2 are supported.
The eight caps C supported on the front end of the ejector 7 are simultaneously lifted by the ejector 7 and the ejector 11.

A spacer 16 having an upper end conforming to the shape of the inner peripheral surface of the cap C is fixed to the stopper 3 facing the three columns of cap carrying walking beams 2 for carrying the cap C (see FIG. 7). Therefore, the leading cap C transported by the cap transport walking beam 2 contacts the spacer 16, and the leading cap C is lifted to a position above the spacer 16 by the ejector 7.

The cylinder 17 arranged horizontally above the first walking beam device WB ₁ has a pusher support member 19 at the tip of an output rod 18 thereof. The pusher support member 19 supports six slide rods 21 urged forward by springs 20 corresponding to the six rows of walking beams 1 and 2, and the rods are attached to the tips of the slide rods 21. A pusher 22 that presses the R or the cap C is provided.

As shown in FIGS. 1 and 2, the first walking beam device W ₁ and the second walking beam device W

As shown in FIGS. 1 and 4, the second walking beam device WB ₂ includes three rows of walking beams for rod transportation 30 for transporting rods R and three rows of walking beams for cap transportation for transporting caps C. The six rows of walking beams 30 and 31 including the beam 31 are arranged in parallel with each other and are driven in synchronization with each other by a common drive source (not shown). Walking beam 30 for rod transportation and walking beam 31 for cap transportation
A forward chute 32 for guiding the rod R or the cap C to the rod carrying walking beam 30 or the cap carrying walking beam 31 is provided at the starting end of the.

A pair of guide rails 33 that are inclined at the same angle as the chute 32 are provided on both left and right sides of the chute 32. On the other hand, a pusher support member 36 is fixed to an output rod 35 of a cylinder 34 horizontally arranged above the second walking beam device WB ₂ , and a pusher support member 36 is vertically attached to a pusher support member 36. A pusher 39 is supported via a slider 38 so as to be able to move up and down. A pair of guide rollers 4 provided on both sides of the pusher 39
0 is guided on the upper surface of the guide rail 33, whereby the pusher 39 moves up and down along the guide rail 33 (that is, along the chute 32). In addition, the pusher support member 36 is provided with a cylinder 41 forcibly raising the pusher 39.

Next, the operation of the embodiment of the present invention having the above construction will be described.

The first walking beam device WB ₁ is driven to convey the rod R by the three rows of rod conveying walking beams 1 and convey the cap C by the three rows of cap conveying walking beams 2. At this time, the rod R is conveyed with the upper end inclined forward, and the leading rod R comes into contact with the stopper 3 and stops (FIG. 5).
(See (A)). On the other hand, the cap C is conveyed in the normal posture, and the cap C at the top is the spacer 1 provided on the stopper 3.
6 and stops (see FIG. 6A).

In this way, when the rod R and the cap C are carried into the ends of the three rows of rod carrying walking beams 1 and the three rows of cap carrying walking beams 2, the cylinder 12 is driven to eject the ejectors 7, 11. Raise all at once. As a result, the leading eight rods R are cut off from the ninth and subsequent rods R locked by the regulation beam 6 and lifted by the ejector 7 (FIG. 5).
(See (B)). As a result, the eight rods R are posture-converted from the inclined posture to the vertical posture by gravity. Similarly, the eight caps C at the head are cut off from the caps C after the ninth cap C locked by the restriction beam 9 and lifted by the ejector 11 (see FIG. 6B). As a result, the top cap C is raised to a position where it does not engage with the spacer 16.

Subsequently, when the cylinder 17 is driven to extend and the pusher supporting member 19 is moved forward, the six pushers 22 provided on the pusher supporting member 19 cause the eighth rod R to move.
The rear end and the rear end of the eight caps C are pressed to push the leading rod R against the stopper 3 for alignment (see FIG. 5C), and the leading cap C is pushed against the stopper 3 for alignment (see FIG. 5C). See FIG. 6C.

Therefore, even if there are variations in the transporting postures and transporting intervals of the rods R and the caps C, the eight rods R and the caps C can be correctly pressed against the stopper 3 and aligned.

In this way, when the rods 8 and the caps C are aligned at the ends of the three rows of rod carrying walking beams 1 and the three rows of cap carrying walking beams 2, respectively, the cylinder 17 is contracted. After driving and retracting the pusher 22, the transfer device T transfers the rod R and the cap C from the first walking beam device WB ₁ to the second walking beam device WB ₂ .

That is, after the transfer device T is moved above the first walking beam device WB ₁ along the guide rail 23, the cylinder 24 is extended and driven to lower the elevating member 26 and the pair of cylinders 27 are used. By driving the pair of chuck plates 29 in the closing direction, for example, eight rods R aligned on the walking beam 1 for rod conveyance are chucked all together. The transfer device T chucking the rod R moves above the second walking beam device WB ₂ , transfers eight rods R onto the corresponding chute 32, and then transfers the next eight rods R. Therefore, it returns above the first walking beam device WB ₁ . In this case, since the same number of rods R and caps C are aligned with the same stopper 3 in the first walking beam device WB ₁ , the common transfer device T can easily and reliably transfer the rods R. The mounting and the transfer of the cap C can be performed.

Thus, the second walking beam device WB
_When 8 rods R are transferred onto the chute 32 of ₂ ,
The cylinder 34 is driven to contract, and the pusher support member 36 is moved from the solid line position in FIG. 4 toward the chain line position. At this time, since the cylinder 41 is in the inoperative state and the pusher 39 is urged downward by gravity, the pusher 3 which moves the guide roller 40 while being guided by the guide rail 33.
9, the eight rods R are discharged from the chute 32 to the rod carrying walking beam 30 while maintaining the aligned state.

In this way, when the eight rods R are delivered to the rod carrying walking beam 30, the cylinder 41 is contracted and driven so that the pusher 39 is raised so as not to interfere with the subsequent rod R or the cap C. In this state, the cylinder 34 is extended to drive the pusher support member 36.
To the original position.

By repeating the above operation,
The rods R or the caps C aligned on the six-row walking beams 1 and 2 of the first walking beam device WB ₁ are
The second walking beam device WB ₁ is sequentially dispensed onto the six rows of walking beams 30, 31. When all the rods R or the caps C aligned on the first walking beam device WB ₁ are discharged by the transfer device T, the ejectors 7 and 11 are returned to their original positions in preparation for the subsequent loading of the rods R and the caps C. To descend.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments, and various design changes can be made.

For example, the first walking beam device WB
The number of rods carrying the walking beam 1 and the cap carrying the walking beam 2 is provided in ₁ is not limited to the three rows, each two rows below, or may be each 4 or more rows. The second transfer device is a walking beam device WB.
The transport device is not limited to _2, and may be another type of transport device.

[0030]

As described above, according to the present invention, the movement of the leading rod and the cap carried by the rod carrying walking beam and the cap carrying walking beam is regulated by the stopper, and the ejector sets a predetermined distance from the leading end. Since a certain number of rods and caps are cut off from the following rods and caps and lifted up, and these rods and caps are pressed against the stoppers by the pushers to be aligned, even if there are variations in the transporting postures and transport intervals of the rods and caps. It is possible to correctly cut out a predetermined number of rods and caps in an aligned state. This makes it possible to easily and reliably transfer the rod and the cap from the first transfer device to the chute. Moreover, since the rod and the cap transferred on the chute are pushed out by the pusher to the second conveying device, the rod and the cap can be supplied to the second conveying device while maintaining the aligned state of the rod and the cap.
