Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for cutting a work material used for a window frame, a door frame, a rim, a waist plate, a door, etc. to an arbitrary length, and more specifically, a related device such as a double end tenona, a molder, a lapping machine. The present invention relates to a work material cutting device that is used by connecting machines and the like in series at the front and rear stages.

[0002]

[Prior art]

 Double-end sizers and cross-cut saws are conventional devices of this type.

The double end sizer is provided with two circular saws which face each other and whose facing distance is variable. In order to cut the work piece using this device, the distance between the two circular saws is adjusted to a predetermined cutting length, and the work piece is moved in the direction along the surfaces of the two circular saws.

When the double-end sizer is connected to a related device, a device for changing the direction of the work material is used between the double-end sizer and the former device and between the double end sizer and the latter device. To be done. For example, if the work material is cut in the vertical direction by the preceding device, cut horizontally by the double end sizer, and the hinge hole and the handle hole are sequentially bored in the vertical direction by the subsequent device, the work material is conveyed to the next device. Every time it is done, the direction is changed. There are two types of devices for changing the direction of the work material, one of which is a combination of a roller conveyor and a belt conveyor so that their conveying directions are different from each other by 90 degrees. Specifically, between the multiple rollers of the roller conveyor, multiple belts that rotate in a direction perpendicular to the direction of rotation of the rollers are provided, and the belt is hidden between the rollers or floats above the rollers. When the work material is conveyed above the belt by the roller conveyor, the belt is levitated to separate the work material from the roller conveyor, and the belt is rotated to move the work material. It is designed to be conveyed to the next device.

The other method is to support one end of the work material and rotate the support. In detail, it consists of a shaft that can be raised and lowered and rotated, and a work material clamping unit attached to the shaft, which holds one end of the delivered work material and raises it to separate the work material from the conveyor, The shaft is rotated and transferred to the next device.

In the cross cut saw, one circular saw and one abutment body are faced to each other, and the facing distance is made variable. To cut a work piece using this device, match the distance between the circular saw and the contact body to a specified cutting length, first cut one side of the work piece with a circular saw, and then cut the end face. To the abutment body and cut the other side with the same circular saw. By the way, the orientation of the work material does not change from the pre-stage device to the post-stage device through this device.

[0007]

[Problems to be solved by the device]

 The conventional double-end sizer has a problem that the equipment cost and the installation area of the equipment increase because a device for changing the direction of each work material is required between the former double-end sizer and the latter-stage device. .

Further, when a device for changing the direction of the work material is used by combining two conveyors by changing the conveying direction, the installation line including the related devices becomes L-shaped and dead space is created on the floor. There is a problem that it easily occurs.

Further, when a device for changing the direction of the work material is used, there is a problem in that it takes time for the change.

In addition, in the above-described cross-cut saw, sawing is performed twice in order to cut one work piece into a predetermined length, so that more time is spent compared with a device that cuts both sides at one time. There is a problem.

The present invention has been made in view of the above problems of the conventional apparatus, and an object thereof is to make it possible to cut a work material into various lengths. To eliminate the need for a device for changing the direction of the work material, to make the installation line including related equipment straight, and to provide a work material cutting device that enables a faster work speed of the work material. It is in.

When the cut piece extruding body 50, 64 moves by driving an air cylinder (not shown), the cut piece in the gutters 44, 62 is discharged to the outside of the apparatus. When the leading edge contact member 66 of the work material is opened and the roller is driven, the work material moves on the roller in the same direction as the introduction direction, and is conveyed to the subsequent apparatus.

Next, a second embodiment will be described. 5 (a) and 5 (b) are longitudinal sectional views showing the same embodiment, and show a state in which the intervals between the two circular saws 12 and 14 are changed from each other. In this figure, details are omitted to avoid complexity.

Reference numerals 202 and 204 denote auxiliary conveyors. In the auxiliary conveyor 202 on the right side of the drawing, the line connecting the axes of the rollers 206 and 208 and the line connecting the axes of the rollers 210 and 212 are parallel to each other, and the roller 206 is in contact with the roller 206.

However, the left auxiliary conveyor is not provided with the roller 216. This roller is for changing the moving path of the belt 218. The necessity of this roller depends on the shape of the support of the rollers 208 and 212, and is not necessary in the case of the left side auxiliary conveyor.

The configuration other than the auxiliary conveyors 202 and 204 and the parts related thereto is basically the same as that of the first embodiment.

Next, the operation of the second embodiment will be described. When the movable table 36 is moved to adjust the distance between the two circular saws 12, 14, the main conveyors 56, 74 move accordingly, and the rollers 206, 214 associated therewith also move. Therefore, the lengths of the conveying surfaces of the auxiliary conveyors 202 and 204 change according to the change in the distance between the circular saw 12 and the front main conveyor 56 and the change in the distance between the rear main conveyor 74 and the device end. In this way, a continuous conveyor surface is always formed between the input and the output of the work piece, even if the distance between the two circular saws 12, 14 changes. The endless belt is always kept in tension even if the length of the conveying surface of the auxiliary conveyor changes.

[Effect of device]

 As described above, the work material cutting device according to the present invention has the main conveyor and the auxiliary conveyor as the continuous length varying means of the conveyor provided between the two circular saws and between the circular saws and the end of the device. Since they are combined, the following effects are achieved.

Since the work material processed by the former-stage device can be introduced without changing the direction, it is possible to omit the device for changing the direction of the work material and save the facility cost and the floor use area.

Further, by omitting the device for changing the direction of the work material, the processing time can be shortened and the production efficiency can be improved.

Furthermore, since the installation line including the related devices is linear, the occurrence of dead space on the floor surface is reduced, and the floor surface utilization efficiency can be improved.
