Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a lateral movement device for bars, cylinders, etc. that transversely transports bars, cylinders, and the like.

[Conventional technology]

2. Description of the Related Art Conventionally, a walking beam used for lateral movement of steel materials, for example, is known as a device for lateral movement of bar materials and the like. A walking beam is used to cross-feed steel materials one after another through the cooperative action of a fixed beam and a movable beam that repeats motion in a nearly elliptical cycle using hydraulic cylinders, link devices, etc.

[Problem that the invention seeks to solve]

However, according to the conventional walking beam, since the link device is operated by a hydraulic cylinder, there is a problem that the traverse speed is slow.

SUMMARY OF THE INVENTION Therefore, the present invention aims to provide a lateral movement device for rods, etc., which allows the lateral movement speed to be made high.

[Means for solving problems]

In order to solve the above problems, the present invention provides a slide frame that is movably mounted on a guide rail on a base frame and that is reciprocated along the guide rail by a reciprocating slider crank mechanism;
A fixed holder is located above the slide frame and attached to the base frame, and supports a plurality of bars parallel to each other at right angles and horizontally to the guide rail, and a crank mechanism provided on the slide frame allows the slide frame to be moved. The movable holder is provided with a movable holder that moves circularly in synchronization with the movement of the slide frame in a vertical plane in the direction of movement, and cooperates with the fixed holder to intermittently feed the bar or the like laterally.

[Effect]

According to the above means, the motion of the movable holder becomes an elliptical motion that is a combination of the reciprocating motion by the reciprocating slider crank mechanism and the circular motion by the crank mechanism that operates in synchronization with the reciprocating motion, and the motion speed is the same as that of both crank mechanisms. Proportional to rotation speed.

Due to the action of the crank rod 31 and rod holder 32, the slide frame 13 is moved to the guide rail 1.
It is moved back and forth along 2. At the same time, the second worm wheel 36 engaged with the upper side of each worm 19 rotates in the same direction together with the second driven shaft 35,
Due to the action of the crank disk 37 and crank plate 38 of the crank mechanism, the movable holder 40 is moved circularly in a plane perpendicular to the moving direction of the slide frame 13, and as shown in FIG. The reciprocating motion by the mechanism and the circular motion by the crank mechanism that operates in synchronization create an elliptical motion, and the fixed holder 1
A bar or the like W placed on one end of the holder 8 is lifted and transversely fed to the other end on the fixed holder 18 one after another intermittently.

When the required number of bars, etc. are placed on the fixed holder 18, the motor 23 placed on the slide frame 13 is stopped, and then the geared motor 45 on the support column 41 is driven, and the sprockets 48, 4 are driven.
6. Rotate the sprocket shaft 44 via the chain 47. The rotation of the sprocket shaft 44 rotates the chain 52 wound around the drive sprocket 49 and the driven sprocket 51, and the pusher 59 moves along the guide shaft 55 together with the chain 52, moving the bar material on the fixed holder 18 along the line. Push upwards.

Thereafter, similar operations are repeated to continuously supply the required number of bars, etc. onto the line.

In the above embodiment, the base frame 3 was provided so as to be movable up and down in order to accommodate changes in the outer diameter of the bar, etc. However, when handling bars with a single outer diameter, the base frame 3 The frame 3 may be fixed.

Further, although both the reciprocating slider crank mechanism and the crank mechanism are operated by the motor 23 mounted on the slide frame 13, the present invention is not limited to this, and the reciprocating slider crank mechanism may be operated by a separate motor mounted on the base frame 3. The crank mechanism may be operated in synchronization with the reciprocating slider crank mechanism by a motor mounted on the slide frame 13.

Furthermore, not only when horizontally feeding a bar or the like, but also by tilting the reciprocating movement of the slide frame 13, tilting the fixed holder 18, and tilting the movement of the movable holder 40, the bar or the like can be moved horizontally. It can also be fed diagonally. In this case, each receiving part of both holders 18 and 40 is shaped so that the bar material etc. will not fall off.

Furthermore, in the case of an unloader that receives a bar or the like by a linen pusher, the pusher 59 etc. may not be provided.

〔Effect of the invention〕

As described above, according to the present invention, the motion of the movable holder is an elliptic motion that is a combination of the reciprocating motion by the reciprocating slider crank mechanism and the circular motion by the crank mechanism that operates in synchronization with the reciprocating motion, so that the reciprocating slider By changing the outer diameter of the crank disk of the crank mechanism, it is possible to arbitrarily change the lateral feed pitch of the bar, etc.

Furthermore, since the moving speed of the movable holder is proportional to the rotational speed of both crank mechanisms, the transverse feed speed of the bar etc. can be dramatically increased compared to the conventional method.
