Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device that conveys a cut piece that has been cut and separated from a work by a cutting machine such as a saw machine. The present invention relates to a cutting piece conveying device in a cutting machine that has a vertical degree of freedom.

[0002]

[Prior art]

 For example, circular saw machines and band saw machines are well known as cutting machines for cutting long materials such as rods. In the above-mentioned cutting machine, a main body vice device is provided close to the cutting position in order to hold and fix a work to be cut by a cutting tool such as a saw blade provided in the cutting machine. Further, a material feeding vise device for carrying in a work to a cutting position is generally provided on the rear side of the main body vise device so as to be reciprocally movable in the front-rear direction.

In the cutting machine having the above structure, the work can be automatically fed to the cutting position of the cutting machine by automating the back-and-forth movement of the material feeding vise device.

Moreover, in order to automate the cutting machine, further, in order to convey the cutting piece cut and separated from the work at the cutting position to the next process, first, the cutting piece is placed on the feed roller in front of the cutting machine. It is necessary to send it on.

[0005]

[Problems to be solved by the device]

 By the way, the cut pieces are clamped by the clamp device and placed on the material feeding roller to be conveyed.If the cut pieces do not warp or bend, the cut piece conveying device is completely guided by the linear guide. No problem.

[0006] However, if the cut piece has a warp or a bend, the cut piece conveying device is crushed by the cut piece and receives an excessive force. Therefore, the conventional cutting piece device does not have the freedom to move with respect to the bending and bending of the cutting piece, and the cutting piece conveying device itself has a problem with respect to the bending and bending of the cutting piece.

In order to improve the above problems, an object of the present invention is to provide an X-axis direction out of three axes of a material feeding direction (X-axis direction), a left-right direction (Y-axis direction) and a vertical direction (Z-axis direction) Since there should be no backlash, it is possible to provide a cutting piece conveying device for a cutting machine, which gives a degree of freedom in two directions of the Y axis and the Z axis and eliminates the problems associated with the bending and bending of the cutting piece. is there.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a device for conveying cut pieces cut by a cutting machine on a material feeding roller, and a conveying frame arranged on the front side of the cutting machine and a cutting position of the cutting machine. A carriage supported on the transport frame so as to be reciprocally movable toward and away from the carriage, and first and second clamp jaws for clamping the cutting pieces, and are reciprocally movable to the left and right. The movable vice body supported by the carriage, the reciprocating actuator for reciprocating the movable vice body in the left-right direction with respect to the carriage, and the movable vice body in which the cut pieces are clamped by both clamp jaws. The cutting piece conveying device in the cutting machine is configured by including a middle shifting device that shifts the material feeding roller upward.

[0009]

[Action]

 By adopting the cutting piece conveying device in the cutting machine of the present invention, by bringing the carriage close to the cutting machine, the cutting pieces cut and separated from the work at the cutting position of the cutting machine are the first and second clamp jaws. Is clamped at. Then, the cut pieces are conveyed forward by advancing the carriage.

When the cutting piece is moved forward, even if the cutting piece is warped or bent, the reciprocating motion device moves the movable vice body in the left-right direction, and the displacement device moves the movable vice body upward. The cut pieces can be smoothly conveyed in the material feeding direction because they have a degree of freedom in the left-right direction and the vertical direction so that they can be displaced in any direction.
