Respective detecting means 21a to 21d detect the passing action of the work timber (W) being cross-sent, and control the corresponding sorting means 22a to 22d one by one, based on this detection signal.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sorting and transferring device for wood or the like, in which the leading ones are sequentially separated and taken out from a group of processed materials which are fed laterally and stored. is there. 2. Description of the Related Art Conventionally, a device shown in FIG. 3 is known as a device for separating and taking out timber fed laterally one by one. That is, the work material W introduced at the start end of the first horizontal feed conveyor A is transferred rearward by the forward rotation of the conveyor and stopped by the stopper means B arranged near the end portion. Then, the processing materials W are accumulated on the conveyor by the successive feeding. Then, when the stopper means B is operated to be retracted, the accumulated processed materials are transferred to the rear as a group. When the leading workpiece W reaches the position of the second transverse feed conveyor C which rotates at high speed, the difference in rotational speed causes
This processed material W and the subsequent processed material group are separated. The second transverse feed conveyor C is provided with a detection means D for detecting the passage of the separated work material W. When the work material W passes through this position, the sorting member E projects on the conveyor. . Further, the sorting member D stops the movement of the subsequent processed material group. The work material W separated as described above is
It is transferred to another position, and its shape is confirmed by, for example, a length measuring means (not shown), and then it is supplied to a predetermined processing position.
Further, the remaining processed material group is returned to the original storage position by the reverse rotation of the first and second lateral feed conveyors A and C, and is again held at the standby position by the stopper means B. The above-described series of operations are repeatedly performed, and the first one can be sequentially separated from the storage material group and taken out, and this can be supplied to a required processing position. When the workpiece W is transferred from the first transverse feed conveyor A to the second transverse feed conveyor C,
With a straight type, since the transfer timing over the entire length is properly performed, it is possible to smoothly perform transverse feed in a parallel state. However, in the case of a warped material or a distorted material, since the delivery timing at the front and rear ends deviates, the processed material is laterally fed in a state of being greatly inclined. However, in such a case, if the sorting member E is projected and controlled based on the passage of one point of the processed material as a reference, the following problems occur. For example, when the workpiece W is tilted and laterally fed as shown in the figure and the passage is detected by the detecting means D, the sorting members E are simultaneously projected. The processed material W rides on the means E and cannot be supplied to the subsequent processing position. Further, if the sorting means is controlled to project when it is tilted contrary to the above, this causes a problem that the timing is delayed and it interferes with the subsequent processed material. The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a sorting device for timber or the like that can accurately sort even a product that is laterally fed in an inclined state. In order to achieve the above object, the sorting and transferring apparatus according to the present invention is constructed as follows. That is, the gist thereof is to provide a first horizontal feed conveyor for laterally feeding a processed material and a second horizontal feed conveyor connected to the first horizontal feed conveyor and rotating at a high speed, The first lateral feed conveyor has a lateral feed position which has stopper means for projecting on the conveyor to store the work material group, and the second lateral feed conveyor has a lateral feed position which projects on the conveyor and is laterally fed. It has a large number of sorting means arranged at intervals in a direction intersecting with the feeding direction, and a detecting means for detecting passage of the processed material in the vicinity of the protruding position of the sorting means. The operation of the sorting means is controlled individually. The processed material is individually detected as passing through a plurality of locations in the longitudinal direction thereof. The sorting means is arranged corresponding to each detection switch, and individually operates according to the detection signal. Therefore, even when the processed material is laterally fed in a tilted state, the sorting means can operate in good timing with passage of each part. Therefore, it does not push up to the sorting material and does not interfere with the succeeding material. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a sorting and transferring apparatus for wood and the like according to the present invention will be specifically described below. In FIG. 1 and FIG. 2, 1 is a low-speed rotating first traverse conveyor 2 is a second traverse conveyor connected to the rear of the first traverse conveyor 1, and the second traverse conveyor 2 is a high speed conveyor. The speed ratio of the two is 1: 7 as an example. In addition, both lateral feed conveyors 1 and 2 have several lines (4 in the embodiment).
Strip chain conveyor, and arranged at appropriate intervals according to the length of the processed material W. Reference numerals 11 and 11 denote stopper means arranged near the end portion of the first transverse feed conveyor 1. The stopper means 11 and 11 are upwardly arranged pneumatic cylinders 12 and 1, respectively.
2 moves in and out of the conveyor surface. A plurality of these stopper means 11 and 11 are arranged in a direction orthogonal to the feeding direction of the lateral feed conveyor 1. Further, the stopper means 11, 11 described above are simultaneously operated by the simultaneous operation of the pneumatic cylinders 12, 12. Numerals 21a to 21d are detection means composed of photoelectric switches arranged above the starting end portion of the second horizontal feed conveyor 2, and irradiate the detection light downward and pass backward depending on the presence or absence of the work material W. Detect motion. This detecting means 21a-
A plurality of (21 in the embodiment) 21d are arranged in a direction orthogonal to the lateral feed direction and detect at least two positions in the longitudinal direction. Reference numerals 22a-22b denote the above-mentioned detection means 21a-.
21d is a sorting means provided corresponding to the sorting means 22a to 22d.
With a to 23d, it moves in and out of the conveyor surface.
These sorting means 22a to 22d are used for the lateral feed conveyor 2
Are arranged in a direction orthogonal to the feeding direction of the above, and are individually operated by the detection signals of the respective detecting means 21a to 21d. Reference numeral 13 denotes a guide plate that regulates one end of the work material W at the time of feeding the work material W, and is arranged on the side of the first transverse feed conveyor 1 and the second transverse feed conveyor 2. 24 is a horizontal feed stop plate disposed above the end of the second horizontal feed conveyor 2
Detecting means 26 for detecting that the work material W is in contact with the lateral feed stop plate 24 is a vertical feed conveyor which is operated by a pneumatic cylinder and projects from the conveyor surface. It is transferred in the longitudinal direction. The structure of the sorting and transferring apparatus according to one embodiment is as described above. For example, when the workpiece W is fed laterally in an oblique state as shown in FIG. 1, first, the detecting means 21a corresponding to the starting end is formed. Detects the passage of the processed material W, and the corresponding sorting means 22a protrudes onto the transverse feed conveyor 2,
Then, the intermediate detecting means 21b detects the processed material W and sequentially operates so that the sorting means 22b projects. This operation is similarly performed for the other detecting means 21c and 21d. As described above, in each part, the sorting means 22a to 22d perform the projecting operation in a timely manner after the processed material W has passed therethrough, so that the smooth sorting operation can be surely performed. Further, it is possible to properly separate the processed material W from the succeeding material. The processed material W taken out by the separation is further transported rearward by the second lateral feed conveyor 2 and comes into contact with the lateral feed stop plate 25 to stop in the orthogonal direction. The subsequent processed material group is sorted by the sorting means 22.
It abuts a to 22d and stops there. Therefore, the sorted work materials W can be transferred by the vertical feed conveyor 26 and supplied to appropriate work positions. Further, the remaining processed material group is temporarily stopped by the stopper means 1 by reversing the two lateral feed conveyors 1 and 2.
It is returned to the front of the conveyors 1 and 11 and then transferred to the contact position of the stopper means 11 and 11 by the normal rotation of these conveyors. By doing so, it is possible to stand by for sorting the next processed material W. In the above embodiment, the stopper means 11, 11 and the sorting means 22a to 22d are projected on the conveyor surface by the ascending operation, but they may be protruded to a predetermined position by the descending operation. In this case, the pneumatic cylinders are arranged downward, and the respective means are configured to operate by switching between an upper retracted position and a lower projected position. Further, in one embodiment, the detection means 21a-21
The detection position of d and the projecting positions of the sorting means 22a to 22d are arranged close to each other in the feeding direction so that the projecting operation is performed immediately after the detection, but the invention is not necessarily limited to this configuration. For example, when the delay means is interposed, the detection position and the protruding position can be separated from each other, which facilitates the attachment of the detection means. As described above, the sorting and transferring apparatus according to the present invention is provided with a large number of detecting means in the longitudinal direction of the work material, and a large number of related sorting means are detected by the detection signals of the detecting means. The operation is controlled individually. Therefore, the sorting means can be operated in good timing regardless of the state in which the processed material is laterally fed, and the sorting work can be reliably performed, which is an excellent effect.
