[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 In this invention, one end or both ends of a plate is processed into a finger shape, and one end of a certain plate is fitted (joined) with a finger at the end of another plate to form a fixed length. 1. Field of the Invention The present invention relates to a finger processing device for processing into a long fixed-length material. In particular, the finger processing device relates to a roll-type continuous transfer device that transfers a finger-joined plate material and a finger processing device including a fixed-length cutting device that cuts the finger-joined plate material to a fixed length.

[0002]

[Prior art]

 After processing and using plate materials and square materials for a predetermined purpose, a large amount of short plate materials remains. Conventionally, from the viewpoint of effective use of resources, such a plate material can be processed into a long plate material or a strong column material by performing finger processing at one end or both ends. As an example of such a finger processing device, a finger processing device as shown in FIG. 13 is used. In this finger processing apparatus, a plate material for processing is moved from a material input section 60 to one end of the apparatus by a roller transport section 61, and transported while holding the plate material by a chain transport apparatus 62, for example. Finger processing is performed on one side of the plate by a finger processing section 63 having a finger cutter installed on the side, and the plate is moved to the other side of the apparatus by a roller conveying section 71, and the sheet is again pressed by a chain conveying apparatus 72. The sheet material W is finger-processed by the finger processing portion 73 provided on the other side.

[0003] Next, the plate material whose both ends are finger-processed is glued to the finger portion by an adhesive application portion 81, rotated by 90 ° and finger-joined by a finger joint portion 82, and further conveyed by a conveying device 91 for a predetermined distance. After being transported and moved, it is cut into a certain size by a cutting device (not shown), and is transferred by being "splashed" by cylinders 92, 92, etc., and is pressed by another pressing device (press device) 93. And firmly joined. Reference numeral 94 denotes a plate stopper when pressure is applied by a pressing device (press device) 93.

[0004]

[Problems to be solved by the invention]

 As described above, in the conventional finger processing device, after applying an adhesive to the finger-processed plate material, a finger-joining is performed by adding a tightening allowance to a predetermined dimension, and “jointly bounced”, and then the bonding material is cut. It requires a laborious work of working and then pressurizing with a pressurizing device to ensure this finger joining. Therefore, there is a problem that it takes a long time from the finger processing to the processing to the long fixed length material, and the processing efficiency is poor. In addition, the lower the processing efficiency, the higher the cost. In addition, as shown in FIG. 13, the conventional finger processing device requires a large area for installation of mechanical equipment because it is necessary to “splash” after finger joining and to measure and cut again. There is also.

The present invention has been made in order to address the above-described problem, does not require a large installation area, has a high processing efficiency, and reduces the cost for producing a long fixed length from scraps. It is an object of the present invention to provide a finger processing device capable of performing the above-described operations.

Reference numeral 54 denotes a bearing that supports the shaft 55. Incidentally, the rotary encoder 53, the plate material holding portion 41 of the plate material cutting device, and the electromagnetic clutch 43j of the moving mechanism 43 are controlled by an arithmetic processing unit (CPU).

The cutting length measuring device 5 measures the cutting length of the plate W, and the cutting unit 42 cuts the plate W in the following manner. (1) First, the sheet material W is conveyed while being loaded by the elastic load means (24, 24) while being sequentially inputted into the sheet material conveying device 1 (the roller conveying devices 2, 3) from the sheet material input section. (2) When the plate material W passes through the exit-side roller transfer device 3 of the plate material transfer device 1, the rotor 52 comes into contact with the surface of the plate material W and rotates while being rotated by a rotary encoder 53 from a predetermined position. Start measurement. (3) When the cutting length approaches the predetermined cutting length, the entire material feeding speed is reduced, and the plate holding portion 41 grips the plate W, and the cutting unit 42 moves at the same speed as the plate W at that speed. (The frame 42b on which the plate material gripper 41 and the cutting unit 42 are installed is moved.) The plate material W is cut when it has a predetermined length, and when the shore is completed, the plate material gripper 41 separates the plate material W and the feed speed is reduced. Speed. (4) Then, the electromagnetic clutch 43j of the moving mechanism 43 is turned ON, and the cutting unit 42 returns to the original position by the motor 43a, the sprockets 43d and 43e, and the chain 43f. (5) When the length approaches the predetermined length again, the sheet feeding speed is reduced, the plate material gripping portion 41 grips the plate material W, and the circular saw 42a automatically determines the position of the cutting length measured by the rotary encoder 53. Disconnect. Such an operation is repeated as many times as necessary.

The rotation speed of each roller may be configured so that the rotation speed gradually decreases from the plate material input side. Further, although the press mechanism and the press release mechanism (load means and load release means for sandwiching the plate material W) of the plate material W use the air mounts 24 and 26, the rollers 2a, 3a,. A configuration may be adopted in which a load is applied to or released from the plate material W through the intermediary. Further, the two roller transporting devices 2 and 3 have been described in the case where the material is fed using one motor 6, the speed reducer 7, the shafts 8, 12, 13 and the sprockets 9, 14, 17 and the like.
