Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a long material pushing device for pushing a laminated product, a prism, or the like, in which long materials such as timber formed into a plate shape are stacked, in the width direction thereof.

[0002]

2. Description of the Related Art Conventionally, for example, a large number of timbers K as shown in FIG. Long material) W,
W,-is obtained, and each obtained plate material W, W, -is given its width dimension b.
According to the above, the sheets are sorted and classified into several types and stacked, and when a predetermined number (for example, 10) of plate materials W, W, -having a width dimension within a predetermined range (for example, 74 mm or more and less than 76 mm) are stacked, 10 It is common practice to pack (band) a laminate made up of sheets of plate material W, W, and cut and cut it to a predetermined length before shipping.

[0003]

As described above, when a stack of several plate materials W is used for packing, sawing or the like, the long stack is kept constant in the width direction without being tilted. It may be required to push quickly by sliding only a distance or into place. For pushing such long materials,
Conventionally, a linear motion actuator such as a fluid pressure cylinder whose speed adjustment and stroke setting are easy is often used. However, since the fluid pressure cylinder has a long overall length and it is necessary to secure a space for the piston rod to project, an extremely large space is required in the width (pushing) direction of the long material to be pushed under normal usage. In many cases, the fluid pressure cylinder cannot be used due to the layout and installation space. In addition, in order to push the long material in its width direction without inclining it, it is required to synchronously press at a plurality of points along the longitudinal direction at the same speed, but this requirement is satisfied. The long material pushing device with high practicality has not been proposed yet.

The present invention has been made in view of such a problem, and an object thereof is to push a long material in a width direction thereof quickly and at a fixed distance or to a predetermined position by using a linear motion actuator. In addition, the layout and installation space are not so restricted, a large space is not required in the feeding direction of the long material, and more than one place can be pressed synchronously at the same speed. The present invention provides a long material pushing device.

[0005]

In order to achieve the above-mentioned object, a long material pushing device according to the present invention has a pair of left and right pushing portions, and each pushing portion has a linear actuator and a long moving member. A swivel arm that swivels in a plane parallel to the material, and a push rod that is vertically provided on the free end side of the swivel arm,
It comprises a pinion fixed to the rotating shaft of the revolving arm and a rack that meshes with the pinion and is moved by the linear actuator, and the racks of the pair of left and right pushing units operate in synchronization. The feature is that they are connected to each other. As a preferred aspect of the present invention, the linear motion actuators of the pair of left and right pushing units, the rack, and the rack connecting synchronous shaft are connected in series on the same straight line and arranged in parallel with the long member. There are things.

In the pushing device having such a structure, when one of the piston rods of the linear actuators of the pair of left and right pushing parts is projected and the other is pulled in, the swing arms of both the pushing parts are moved through the rack and the pinion. In a preferred embodiment, the push rods of the two pushing units are swung in the same direction at the same speed and at the same speed by 180 degrees, so that the push rods turn in the same direction so as to draw a semicircle. It is pushed in the width direction. In this case, since the piston rods of the linear movement actuators of the two pushing units are mechanically connected to each other via the rack and the synchronous shaft so as not to cause a slip, the linear movement actuators of the pair of left and right pushing units are Even if the internal resistance values are different, those piston rods will be ejected synchronously at the same speed and will be pulled back, and as a result, the elongated member will not be inclined and the longitudinal direction will be increased. It is possible to quickly push a fixed distance or a predetermined position without moving.

Further, since the linear motion of the piston rod of the linear actuator is converted into the rotational motion by the rack and the pinion and the push rod is swung to push the long material, the linear actuator Since the degree of freedom of installation (posture) is increased and it is not necessary to arrange the long material along the pushing direction of the long material, a large space is not required in the width (pushing) direction of the long material. The layout is easy, and the device can be installed in a restricted space.
