榛材の定寸機構は榛材を搬送手段上に直接積載し、搬送
手段の移動距離を感知する構成をしている。Rod-shaped members such as pipes, round bars, and shaped steel (hereinafter referred to as cylindrical materials) are manufactured to standardized lengths. The user then performs mechanical processing such as cutting and bending on the purchased birch wood to produce the desired birch wood. For example, a machine manufacturer produces a large number of steel shapes of a predetermined length by feeding purchased steel shapes a predetermined length using a conveyor and cutting them repeatedly, and these steel shapes are used as frame materials for machines. Further, reinforcing bars for reinforced concrete are fed a predetermined length by a conveying means and then bent into a desired L-shape or channel shape. A conventionally known sizing mechanism for bamboo wood is configured to directly load the bamboo wood onto a conveyance means and sense the distance traveled by the conveyance means.

り方法および定寸送り機構の提供を目的としている。When the conveyance means has been fed a predetermined length, the conveyance means is stopped to feed the birch material by a predetermined length. With such a known configuration, it is difficult to obtain sufficient machining accuracy because the movement tolerance of the conveying means is accumulated when a large number of machining processes are performed on the bamboo wood. Further, if there is a gap between the feeding member fixed to the conveyance means and the rear end of the twill material, the wicker material will slip on the conveyance means, and the moving distance of the conveyance means will not match the amount of feed of the twill material. Therefore, it is necessary to sufficiently press the rear ends of the materials against the sending part to prevent them from occurring in the dark, making it difficult to set the birch materials on the conveyance means. The object of the present invention is to provide a method and a mechanism for feeding Japanese bamboo to a fixed size, which eliminates the drawbacks of the known techniques as described above.

定寸送り機構１２はこのような応用例だけでなく他の分
野にも応用できることはいうまでもない。First, for example, four strips 14 are placed into the guide means 20 as shown in FIG. 4A. Then, when the conveying means 22 is operated, the feeding member 32 of the conveying means comes into contact with the rear end of the weight material (see Fig. 4B) and moves together with the weight material. The tip of the material 14 comes into contact with the stopper 34 (see FIG. 4C). Here, since the stopper 34 is given a biasing force in the direction of the reference position by the pneumatic cylinder unit 42, the camellia material 14 is firmly clamped between the stopper 34 and the feed member 32, and the birch material is Even if the pieces are placed in the front or back, they will be perfectly aligned. When the stopper 34 is moved, for example, by F, 1× from the reference position, and the bamboo wood 14 is fed by F from the reference origin (see Figure 4D), the sizing gauge 60 senses the passage of the stopper and transfers it to the conveying means. The driving force is used to stop the operation of the conveying means. Thereafter, the bending roller 72 is driven to perform a desired bending process. A biasing force in the direction of the reference position is constantly applied to the stopper 34, so that if the bamboo leaves the stopper during bending, the stopper automatically returns to the reference position. When the first bending process is completed, the birch material 14 has been processed into the shape shown in FIGS. 5A to 5B. When the first bending process is completed, the driving force is transmitted again to the conveying means 22, and the feeding member 32 further advances from the position shown in FIG. 4D while holding the grain material 14 between it and the topper 34. The feed member 32 moves from the position shown in FIG. 40 to F2-F,
If the stopper 34 moves by Fe−
(Figure 4E). Therefore, when the sizing gauge 59 senses the passing of the stopper 34, the operation of the conveying means 22 is stopped, and the second bending process is performed in the same manner as described above, and the bamboo material is processed as shown in FIG. 5C. Thereafter, by further operating the conveying means 22 and moving the feeding member 32 by F3-F2 from the position shown in FIG. 4E, the bamboo wood 14 is eventually fed by F3 from the reference origin. Then, the sizing gauge 58 senses the passage of the stopper 34, stops the operation of the conveyance means 22, and performs the third bending process. After passing through the first to third bending processes, the shank material 14 is finally processed into the shape shown in FIG. 5D, completing a predetermined cycle. When a series of predetermined cycles are completed, the processed bamboo material 14 is removed from the guide means 20, and the conveyance means 22 is driven in the opposite direction, so that the sent material 32 is returned to its initial state as shown in FIG. 4A. Ru. When the twill material 14 is removed from the guide means 20, the stopper 34 is automatically returned to the reference position by the biasing force of the pneumatic sealing unit 42, and all preparations for the next cycle are completed. Then, the birch wood 14 is placed into the guide means 20 again and the same cycle as described above is repeated one after another, thereby producing birch wood 14 one after another as shown in FIG. 5D. In the embodiment, the pressing and bending mechanism 16 is equipped with the fixed length feeding mechanism 1 of the present invention.
2 are combined to form the pressing and bending mechanism 10, but it goes without saying that the fixed length feed mechanism 12 of the present invention can be applied not only to this application example but also to other fields.

材とを具備している。Then, the bamboo wood is further conveyed while being held between the stopper placed at the standard position and the feeding member, and when the stopper moves a predetermined distance from the standard position, this is sensed and the conveying process of the conveying means is stopped. There is. In such a fixed-size feeding method, even when a large number of bamboo pieces are conveyed at the same time, the pieces are held between the feeder and the stopper and are automatically aligned. Therefore, it is not necessary to set the rear end of the birch material in contact with the feeding member, and the subsequent material can be easily set. Furthermore, since the birch material moves while being held between the stopper and the feed material, they move as one and there is no play between them. Since the movement of the stopper from the reference position, which is located a certain distance from the reference origin, which is a problem in a given process, is sensed and the operation of the transport means is stopped, errors in the movement amount of the transport means may be caused. It is possible to accurately control the feed rate of the bamboo material, regardless of the Even when the twill material is repeatedly fed, the feed amount of the twill material is always controlled based on the reference position of the stopper, so that the error in the twill material is not gradually reduced. Further, the sizing feeding mechanism directly used to carry out the sizing feeding method for twill materials according to the present invention includes a guide means for storing the twill material, a conveying means that moves along the guide means, and a conveying means fixed to the conveying means. The feeding member is provided with a feeding member that touches the rear end of the bamboo material and moves the bamboo material integrally along the guide means during the operation.

。Furthermore, the foot length mechanism is movably disposed at the reference position by applying a return force to the reference position, and the tip of the twill material that moves integrally with the feeding member comes into contact with the twill material. A stopper that moves against the return force while holding the conveyance means, and a sensing means that senses that the stopper has moved a predetermined distance from a reference position and stops the operation of the conveying means. In such a basic sizing feeding mechanism, even when a large number of bamboo pieces are conveyed at the same time, the pieces are automatically aligned by being held between the stopper and the feeding member fixed on the conveyance means. Since the bamboo wood is sandwiched between the stopper and the sender, there is no play and it moves completely as one piece. Furthermore, since the movement of the stopper is sensed by the sensing means and the movement of the stopper is controlled, rather than the amount of movement of the conveyance means, which is prone to errors, the amount of feed of the birch material can be accurately controlled. Furthermore, since the feed amount of the Kabamura is always controlled based on the reference position of the stopper, errors in the feed amount do not accumulate. Since the stopper always applies biasing force in the direction of the reference position, it is possible to further ensure the clamping of the bamboo material between the feed material and the material, and the stopper automatically returns to the reference position after the completion of a series of cycles. to return to normal. Here, it is preferable to apply a biasing force to the stopper using a pneumatic cylinder schnit or a hydraulic cylinder schnit as in the embodiment, since the same biasing force can always be applied regardless of the amount of movement of the stopper. The above-mentioned embodiments are for illustrating the present invention and are not intended to limit the present invention in any way, and all modifications and modifications within the technical scope of the present invention are also included in the present invention. Needless to say, it will be done.

どのような形態であってもよい。For example, the guide means and the feeding member are not limited to the form shown in the drawings, but the feeding member fixed to the conveying means comes into contact with the rear end of the bamboo wood stored in the guide means, so that the bamboo wood and the feeding material are guided. Any form may be used as long as it moves integrally along the means.
