Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer device for a wood processing machine which can efficiently perform tenon processing. In the conventional frame construction method, columns, beams and the like are used as structural materials, and various members are subjected to mortise processing in order to connect them to each other. For example, this processing is roughly divided into a wood mouth part (end part) and a side part (intermediate part)
Since it has a tenon shape that is different from each other and has different tenon shapes at each place, and each female tenon and male tenon, it is very complicated and requires many kinds of dedicated processing machines for processing. Therefore, when processing with a single-purpose machine, it is an important point to achieve efficiency by properly laying out these and connecting the lines with a conveyor. FIG. 17 is an explanatory view showing an outline of a conventional tenon processing system. That is, the processed material W put on the carry-in conveyor A is sent to the cross-cut saw C by the vertical feed conveyor B, and the front end and the rear end are cut there to be finished into a constant-sized material. The constant-size material (working material W) transferred to the vertical feed conveyor D behind the cross-cut saw C is fed to the first horizontal feed conveyor E and is stored on the transport surface thereof. The stored processing material W is transferred backward along with the lateral feeding, and is sequentially supplied onto the first vertical feeding conveyor F from the end. The processing material W supplied onto the first vertical feed conveyor F is sent only to the corners to the processing machine G, where the upper and lower surfaces are subjected to corner processing. This processed material W
Return to the first longitudinal feed conveyor F, where they are fed onto the second horizontal feed conveyor H and stored on their transport surface. The stored processed material W is transferred to the rear in the same manner as described above, and the processed material W is transferred to the second end in order from the end.
Of the vertical feed conveyor J. The work material W on the second vertical feed conveyor J is the first horizontal tenon mortise processing machine K.
It is sent to, where the side part is subjected to female mortise processing. In the following, the work material W moves laterally while being stored on the third to seventh lateral feed conveyors S, T, U, V and X, and in the meanwhile, the second lateral tenon machine. L, a router processing machine M, a stud rafter processing machine N, a front-end mortise processing machine P, and a rear-end mortise processing machine Q perform mortise processing, and a unloading conveyor R at the rear end sends the mortise back. In addition, a vertical feed conveyor having no reference numeral is arranged between the horizontal feed conveyors S, T, U, V, and X. [0006] As described above, in the conventional machining system, the machining material can handle all mortises, but the structural materials such as columns and beams are used at the places where they are used. It usually has a unique shape due to the difference. Therefore, it is extremely rare that it is necessary to pass through all the processing machines, and it is the actual situation that most of the members can be mortise processed by several kinds of processing machines. In such a case, conventionally, the work material W on the front-stage horizontal feed conveyor is skipped and supplied onto the rear-stage horizontal feed conveyor via the vertical feed conveyor to improve the work efficiency. However, the conventional processing system configuration is
The workpiece W is present on the vertical feed conveyor during the operation of the tenon processing machine. For example, the workpiece W cannot be skipped unless the workpiece W is retracted to the rear receiving conveyor Y. was there. That is, there is a problem that the flow of the processed material becomes worse on the contrary when the operation rate is increased, and further improvement is required to achieve efficient work. The present invention has been made by paying attention to the above-mentioned problems of the prior art, and enables the work material to be directly transferred between the front-stage and rear-stage transverse feed conveyors. An object of the present invention is to provide a transfer device for a wood processing machine that can ensure a smooth flow of a processed material and can perform efficient work. In order to achieve the above object, a transfer device for a wood processing machine according to the present invention is configured as follows. That is, the gist of the point is that a large number of horizontal feed conveyors that horizontally feed a long workpiece are arranged in the transfer direction, and a vertical feed conveyor that vertically feeds the workpiece is provided between each horizontal feed conveyor. In the wood processing apparatus for transferring the processed material to the processing machine side by this vertical feed conveyor, a mounting table for holding the processed material in standby is provided at the front side position of the vertical feed conveyor, and the preceding horizontal feed conveyor is also provided. First transfer means for transferring the processed material stored at the rear end position to the standby position, second transfer means for transferring the processed material at the standby position to the vertical feed conveyor, and the processed material on the vertical feed conveyor Is provided to the front end position of the subsequent horizontal feed conveyor, and the fourth transfer means for transferring the processed material at the rear end of the previous horizontal feed conveyor to the front end position of the subsequent horizontal feed conveyor. Especially. When performing mortise processing, the first and second transfer means are operated to feed the work material on the preceding horizontal feed conveyor to the mounting table, and from this mounting table to the vertical feeding conveyor. Transfer. When the mortise processing is completed, the third transfer means is operated to feed the processed material on the vertical feed conveyor to the horizontal feed conveyor in the subsequent stage. Further, when jumping over the processed material, the fourth transfer means is operated to directly transfer the processed material of the horizontal feed conveyor of the preceding stage to the horizontal feed conveyor of the subsequent stage.

The pneumatic cylinder 15 in the above-mentioned first transfer means 10 operates independently, and the work material W supplied to the end portion of the transverse feed conveyor C1 (C2, C3) is conveyed on the conveying surface. Lift and hold. Also in the third transfer means 30, the pneumatic cylinder 35 operates independently, and holds the processed material W at the standby position on the transport surface at the starting end of the transverse feed conveyor C1 (C2, C3). Whether the first and third transfer means 10 and 30 are operated in series or in a fragmentary manner as described above detects the presence or absence of the processed material W at the next transfer position. It is made by the signal of the detection means. The construction of the tenon processing system according to one embodiment is as described above, and an efficient processing operation can be achieved under a smooth transfer as follows. First, FIG.
The work material W1 cut to a constant size with a cross-cut saw (not shown) is supplied to the starting end of the first horizontal feed conveyor C1 from above the vertical feed conveyor Ao. The vertical feed conveyor Ao has the same height as the horizontal feed conveyor C1, and the processed material W is transferred by the starting end transfer means 30a configured similarly to the third transfer means 30. When no other work material W is present on the first transverse feed conveyor C1, this conveyor rotates in the normal direction and transfers the work material W1 to the end position. When the processed material W1 reaches the end of the conveyor, the normal rotation is stopped by the detection switch means (not shown). In addition, when the constant-size cutting by the cross-cut saw is completed during the transfer of the processed material W1, the processed material W2 is
It is held above the starting end of the first transverse feed conveyor C1.
(See FIG. 7) This holding position is a standby position that does not reach the conveyance surface. The work material W1 at the end of the first horizontal feed conveyor C1 is lifted upward by the first transfer means 10 and set at the standby position. In the above state, when the mortise processing machine A1 is cutting and there is a processed material on the mounting table Da, the processed material W2 at the starting end of the transverse feed conveyor C1 is supplied to the conveying surface, Then, the conveyor C1 is fed slightly backward by the forward rotation of the conveyor C1 (width pitch of the processed material W). (Refer to FIG. 8) By this transfer operation, a space for receiving the next processed material is formed at the start end of the transverse feed conveyor C1.
At this time, when the cutting work by the mortise processing machine A1 continues, the next sizing work material W3 is supplied to the lateral feed conveyor C1. (See FIG. 9) Thus, several processed materials W1 to
W3 is stored on the lateral feed conveyor C1. (Refer to FIG. 10) When the cutting process by the mortise processing machine A1 is completed in the state where several pieces are stored, the third transfer means 30
Thus, the processed workpiece Wm is sent to the starting end of the second horizontal feed conveyor C2. (See FIG. 11) Further, the second transfer means 20 supplies the next processed material Wn onto the first vertical feed conveyor Aa. Further, the first transfer means 1
The work material W1 in the standby position is supplied to the mounting table Da by 0. (Refer to FIG. 12) When the transfer of the processed material W1 is completed, the first lateral feed conveyor C1 rotates in the normal direction, and the stored processed material W
2 to W4 are transferred backward. And the processed material W at the top
When 2 reaches the end, traverse stops. (See FIG. 13) The processed material Wn on the first vertical feed conveyor Aa is fed to the mortise processing machine A1 and subjected to cutting. Here, in the case where the work material W2 reaching the end of the first transverse feed conveyor C1 is cut by the mortise processing machine A1, it is held at the upper standby position by the operation of the first transfer means 10. To be done. The work materials W3 and W4 are returned to the front by the reverse rotation of the first transverse feed conveyor C1 in order to store the work materials W3 and W4 at a predetermined pitch without any gap. (See FIG. 14) The operation thereafter is the same as that described above. Whether or not the above-mentioned processed material W2 requires cutting processing is determined by reading a bar code (not shown) information attached at an appropriate position. On the contrary, when the machining of the workpiece W2 is not required, the fourth transfer means 40 is operated to feed the workpiece W2 from the end of the conveyor to the start of the second transverse conveyor C2. It should be noted that this transfer is performed after confirming that there is no preceding processed material at the starting end of the second horizontal feed conveyor C2.
(See FIG. 15 and FIG. 16) After the jump transfer of the work material W2, the next work material W3 is transferred to the end of the first lateral feed conveyor C1. For this processed material W3 as well, the transfer processing based on the bar code information is performed as described above. In the above embodiment, the first transfer means 10 to the fourth transfer means 40 are separately constructed. However, since all of these transfer means are simple ones that combine the raising and lowering operation and the back and forth operation, it is possible to summarize the configuration. For example, if a drive motor whose position can be easily controlled, or a hydraulic cylinder or a pneumatic cylinder that can set multistage positions is used as a drive source, four transfer means 10 to 40 can be combined into one or two. Further, in one embodiment, the transverse feed conveyor C1
Longitudinal conveyor Aa (B from the conveying surface of (C2, C3)
Although the conveyance surface in b) is set low, it may be the same or high. In this case, in the former case, the operation range of the fourth transfer means 40 becomes large, and in the latter case, the operation range of the first and third transfer means 10, 30 becomes large, but this can be easily covered in design. . As described above, the transfer device for a wood working machine according to the present invention directly transfers from the front-stage horizontal feed conveyor to the rear-stage horizontal feed conveyor even when the mortise processing machine is in operation. It is possible to jump over and transfer processed materials. Therefore, the flow of the processed material is dramatically improved, and the excellent effect that the processing operation can be performed efficiently is exhibited.
