Description

[Detailed description of the invention] This invention relates to sawing equipment.

As a device for dividing materials into small pieces in a conventional sawmill,
The one shown in Figure 1 of the drawing is known, and this one is a band saw
A saw machine A is equipped with a ruler 3 on one side of a material feeding table 2 and a corresponding e-feeding roller 4 on the other side, with a sawing path in between to carry out products and leftover materials. conveyors 5 and 6 are provided,
A transfer conveyor 7 for returning the remaining material to the material feeding table 2 is provided on one side of the remaining material carrying out conveyor 6, and when the material reaches the position of the detector 8 when the middle t of the remaining material carrying out conveyor 6 falls, the material reaches the position of the detector 8.
When the detector 8 is operated, the remaining material is transferred to the return conveyor 7.
A transverse feed means 9 that operates in this manner was provided.

Therefore, when an operator stands in front of the material feeding table 2 of the saw machine AE, inserts the material between the ruler 3 and the feeding roller 4, and the material is sawn into pieces, the detector 8 detects sawing and splitting, activates the cross-feeding means 9, transfers the remaining material to the return conveyor 7 and returns it to the material feeding table 2, so if the remaining material is received and a product can still be obtained, the material feeding tape)v
If the scraps cannot be removed, they must be thrown off the processing conveyor (not shown in the drawing), which is dangerous because the operator stands near saw machine A. In addition, this method, in which materials are relayed and transferred using multiple conveyors, has low work efficiency because continuous sawing is not possible, and the material feeding device is large. The drawback was that it required a large amount of expense.

The present invention has been made to solve this problem, and by using a circulating conveyor equipped with a material feeding table, if the material is supplied at a position away from the saw machine, the material can be continuously fed to the saw machine. The purpose of the present invention is to provide a recirculating material-type sawing device u that can safely and efficiently produce sawn wood and has low facility costs.

Next, an example of the implementation of the recycled material type sawing device according to the present invention will be described below with reference to FIG. m1.

In Figures 2 and 3 of the drawings, A is a saw machine, and the frame 10 is
A pair of upper and lower chain wheels 11, ]2 are pivotally supported, and a band saw 13 is stretched between these chain wheels 11, 12, and on one side of the band saw 13 there is a sawn material ruler whose spacing can be freely adjusted. 14 is provided. Reference numeral 15 denotes a conveyor installed on one side of the saw machine A so as to run straight from the front to the rear near the saw 13, and return directly from the rear to the front outside of this straight-travel section. Chain wheels 16 and 17 are stretched, and the rear chain wheel 17
is driven by the reducer motor 18. Reference numeral 19 denotes a plurality of material feeding tables attached to the conveyor 15 at a pitch that does not interfere with each other, and the lower central part of the tables is attached to the conveyor 15 with a shaft 20,
Rollers 21, 21 are attached to the front end and the rear end of the guide means 1, which will be described later, to constantly direct the material feeding table 19 in the front and back direction. 22 , 23 , 24 , and 25 are guide means for directing the circulation movement of the material feeding table 19 back and forth, and the outer guide means 22 is parallel to the straight forward portion and the straight backward portion of the conveyor 15. Straight sections A, A and the diffraction section t of the conveyor 15
The middle guide means 23 of the inner guide means 23 and 24 is formed by the two diffraction section openings connected together, and the middle guide means 23 is formed by the outer guide means 23 and 24 on the side part of the saw machine A and the part on the opposite side thereof. Rollers 21 provided before and after the material feeding table 19 between the rollers 21 and the means 22
.
The outer guide means 22 is placed along one opening of the diffraction section in the
Between the front and rear rollers 21 of the material feeding table 19F, the rollers 21 are moved from the straight forward section to the rectilinear section or from the rectilinear section to the rectilinear section while the material feeding table 9 is facing in the front and back direction. To do this, the distance between the center of the gap between the diffraction section opening of the guide means 22 and the guide means 24 and the center of the diffraction section of the conveyor 15 is adjusted between the center axis 20 of the material feeding table 19 and the rollers at both ends. 21,
The distance between the shafts of the chain wheels 16 and 21 shall be equal to 1, and the rollers 2 of the material feeding table 19 are located inside the chain wheels 16 and +7.
A guide means 25 for supporting 1 shall be provided. Reference numeral 26 denotes a large number of rollers attached to one straight portion of the guide means 22 and 23, which roll into contact with the material feeding table 19, so that even if a heavy material is placed on the material feeding table 19, the material feeding table 19 remains light. It looks like it's moving.

27, 27 are means for holding the material provided on the material feeding table 19. In the case of the both-end clamping type shown in FIG. 2, one holding means 27 is fixed, and the other is shown in FIG. If the cylinder 28 is used to move the material forward and backward as shown in FIG. 30 is attached, and the holding means 25 is raised and lowered from this cylinder 30t. Furthermore, this holding means 27,
27 is a roller type as shown in Figure q and Figure 5 T,
The material is of a sliding plate type, and when lateral pressure is applied from the pushing means (to be described later) or the pushing means (t) described below, the material is pressed against the ruler 14 or fed by the rotation of the rollers or the sliding of the sliding plate. It is preferable that the material is splashed off from the table 19. 31 is the side 1 of the receding part of the conveyor 15;
The provided material feeding section receives the material from the conveyor 32f and sends this material onto the material feeding table 19. Reference numeral 33 denotes a scrap scraping means provided on the rear side of the material feeding section 31, which is normally lowered by the elevating means 34 to a position that does not impede the lateral movement of the material feeding table 19, and the scrap scraps on the material feeding table 19 is When you want to jump off the
The lifting means 34F raises the scraps to a corresponding position, and the cylinder 35 feeds the scraps toward the scraps, causing the scraps to fall onto the carrying-out means 36. 37 is the conveyor 15 mentioned above.
A pressing means provided corresponding to the ruler 14 of the saw saw machine A on one side of the straight section in one row uses a roller supported by a swinging arm 391 operated by a cylinder 38. Note that the pressure applied by the pressing means 37 may be applied by suspending a weight from a wire tied to the swinging arm 39 and applying pressure from this weight. Reference numeral 40 denotes a product delivery means provided at the rear of the saw machine A, which receives the products sawn from the material by the band saw 13 and transports them to the product storage area.

One of the chain wheels 1.6 and 17 on which the conveyor in the recirculating material sawing device constructed as described above] 5 is stretched.
When rotated by the reducer motor 181, the conveyor]
5 repeats the circular motion of moving from the front to the rear through the straight section, changing direction at the turning section, returning from the rear to the front at the turning section, changing direction at the turning section, and proceeding through the straight section. The plurality of material feeding tables 19, which are attached to the shaft 20 at the center of the conveyor 151, are connected to the straight section A of the outer guiding means 22 and the inner guiding means 23 in the straight moving part and the straight retreating part of the conveyor 15. Since the front and rear rollers 21 and 21 are sandwiched between the front and rear rollers 21, 21 are correctly oriented in the front and rear directions.
) from which one roller 21 is held, and the other roller 21
Since 25 guide means move in contact with each other, this portion t also undergoes circular motion directed in the front-rear direction. Therefore, when the material is sequentially supplied from the material supply section 301 to the material holding means 27 and 27 on the second feed material table 19, the supplied material is turned at the turning section on the front side, and when it advances through the straight section, it is pushed by the pressing means. 37, pressed against the ruler 17 by 37,
After being fed into the band saw 13 and sawn into the product and the remaining material, the product falls to the carrying-out means 40, and the remaining material is supported by the feeding table and turned at the rear turning section t. is,
The operator repeats the operation of returning through the straight section, turning at the front turning section, pressing the straight section against the ruler 14 by the pressing means 37, 37, and sawing the material again. After monitoring, if the remaining material is a scrap material E that cannot be removed as a product, the scrap material is splashed off from the material feeding table 1 through the means 331.
9 to the unloading means 36, and supplying new material to the material holding means 27, 27 on the empty material feeding table 19, the circulation movement of the plurality of material feeding tables 19 can be reduced by one rotation. It is possible to continuously feed material to the single saw machine A and perform sawing with extremely high efficiency.

The recirculating material type sawing device related to the present invention 1 includes a saw that is driven by a power F to saw the material, and after moving straight from the front to the rear on one side of the saw, the outside of this straight section is moved backward. a conveyor that moves straight forward from the conveyor, a plurality of material feeding tables whose intermediate portions are pivoted to the conveyor and whose directions are determined by guide means, and material holding means for holding the material on the material feeding tables. and a material feeding section for supplying material to a material feeding table on the opposite side of the saw, and a pressing means for pressing the material on the material feeding table against a sawn material ruler in front of the saw, In the material supply section, material is supplied onto each material feeding table, and when the conveyor is operated, the material feeding table moves straight on the saw machine side and goes straight on the opposite side, performing a circular motion to feed the materials one after another to the saw. Since the pushing means presses the material against the sawn material ruler and determines the material, the material is sawn continuously by one saw, which not only greatly increases work efficiency but also saves the worker. The machine monitors the recycled materials at a location F far from the saw machine, and when the material becomes scraps that cannot be used for products, it can be transformed into new materials. The work can be carried out safely without the risk of accidents, and since the material feeding device is small in the cylinder made up of a single conveyor, it has the unique effect of reducing facility costs. It is something.
