Description

[Detailed Description of the Invention] (Objective of the Invention) <Industrial Application Field> The present invention is applicable to applications where the sawing direction is non-vertical, such as a horizontal portable saw or an inclined band saw having a slightly inclined sawing surface. This relates to a material feeding device that is compatible with the set band 'Jffi.

<Prior art and its problems> For example, in a horizontal portable saw, the saw blade acts horizontally on the transported sawn material, so the sawed material tends to be drawn in in the direction of action of the saw blade. For this reason, as shown in Figure 9, when the back plate that is the sawn material is further sawed and split, even if there is space to feed the material for two pieces at a time, the sawn material is pushed to one side, The work cannot be carried out smoothly, and the cutting accuracy cannot be achieved accurately. A similar problem arises, for example, when sawing two pieces of sawn wood, one of which is sent as a product or to another processing process, so it must be transported in a straight line, and If other sawn materials are returned as return materials because they need to be processed again, the existence of this problem with horizontal sawing also poses the problem of not being able to sort the sawn materials smoothly. are doing.

Technical Problems Tried to Solve> The present invention was made in view of the problems of the conventional method, and it is possible to use this type of horizontal sawing machine or a band saw machine with a near-horizontal sawing angle, even if the sawn material is The aim was to develop a new material feeding device in which adjacent sawn materials do not collide or interfere with each other even when they are pulled in by the blade.

(Structure of the Invention) <Means for Achieving the Object> The material feeding device for a non-vertical portable saw according to the present invention is attached to a band saw set in a non-vertical direction, and is conveyed along the sawn surface by the band saw blade. In a device that has a working surface and that travels perpendicularly to the traveling direction of the bandsaw blade to transport the sawn material, a partition member is provided that protrudes from the transport working surface and runs along the transporting direction. This feature is intended to achieve the above objective.

<Examples> The present invention will be specifically described below based on illustrated examples. Reference numeral 1 denotes a material feeding device according to the present invention, which is applied to a so-called horizontal sawing band saw 2. Of course, this band saw machine 2 is set so that the direction of sawing action is horizontal or close to it, and in short, the sawing trajectory is set in a non-vertical state, and when sawing, it cuts in the horizontal direction of the sawn material A. It can be applied to any type of equipment where deviation of the position is a problem. To explain these below, reference numeral 3 is a base frame that is attached to the foundation and is used for the band saw $2.
and the material feeding device 1. That is, two vertically parallel guide rails 4 are provided on the surface of the base frame 3 on the bandsaw machine 2 side, and a slide guide 5 that engages with the guide rails in a substantially dovetail groove shape is attached to the guide rails 4. 5 is integrally assembled with the machine frame 6 of the band saw machine 2.
Ru. Therefore, the machine frame 6 is attached so that it can move up and down relative to the base frame 3, and for this shift, a lifting motor M1 is mounted on the base frame 3, and Drives the screw jack 9 to control the elevation and descent of the machine frame 6,
A drive tire 10 and a tension tire 11 are attached to the band saw machine 2 so as to face each other on the left and right sides, and the drive tire 10 is fixedly supported on the machine frame 6. Note that rotation is transmitted to the drive tire 10 from a motor, but illustration thereof is omitted. On the other hand, the tension tire 11 is supported by a bearing 13 on the end side of a spall 12 that is attached to the frame 6 of the machine so as to be slidable in the horizontal direction. The constant tension tire 11 is regulated in a direction away from the drive tire 10 by a biasing member 14 such as the above. The band saw blade 15 is suspended between the pair of driving tires 10 and the tension tire 11, and in this embodiment, the traveling trajectory above the band saw blade 15 is used as the sawing and splitting trajectory. The material feeding device 1, which is a characteristic structure of the present invention, is used on the lower surface of the sawing track in such a bandsaw machine 2.

A conveyor frame 17 fixedly supported by the cutting base frame 3 is disposed in the front and back so as to be perpendicular to the sawing track below the cutting track of the band saw blade 15, and a conveyor slat 19 supported by a chain 18 is disposed therein. Run many times. Specifically, a tension sprocket 20 and a drive sprocket 21 are arranged at the front and rear of the conveyor frame 17, and the chains are suspended there, and each chain 18 is equipped with a large number of conveyor slats 19 to form a so-called slat conveyor. Configure. With this configuration, the conveying surface of this material is set to be parallel to and orthogonal to the sawing surface of the band saw blade 15.

A partition protrusion 23 serving as a partition member, which is a characteristic feature of the present invention, is provided at the center as an example of the conveyor slat 19. Of course, the purpose of this partition protrusion 23 is to prevent the sawn material A from shifting from a certain range during sawing work, so it is not necessary to attach it to all the conveyor slats 19, as shown in FIG. 6(a). Conveyor slats 1 at regular intervals to the extent that the purpose is partially achieved as shown in
An appropriate method, such as providing it at 9, can be taken. In addition, in many cases, a partition protrusion 23 is provided as a partition member in the center because two pieces of sawn material A are often processed due to work efficiency, etc., but conveyor slats are used as shown in Fig. 6(b). 19 may be provided in several rows in the horizontal direction. Furthermore, in order to freely set the partition range, the partition protrusion 23 is constructed of a member that can be partially removed or retracted from the conveyor slat 19, as shown in FIG. 6(C), and it can be selectively protruded. Of course, there is no problem in allowing various positions to be selected by doing so.

Furthermore, since the partition projection 23 only needs to protrude at least from the surface where the conveying action is performed, the partition projection 23 is rotatably attached to the conveyor slat 19 as shown in FIG. It may be guided by a cam plate C or the like such that it protrudes only at the transport position. Furthermore, partition protrusions may be formed on slat conveyors such as chain conveyors, belt conveyors, etc. to the extent that the purpose is achieved.

On the other hand, as the other component of the material feeding device 1, a pressing roller 26 having spikes 25 on its surface is provided above the conveyor 16. This pressing roller 26 is the band saw blade 2
A presser roller support frame 2 is configured to rise and fall integrally with the machine frame 6 and surround the conveyor 16 in a gate shape.
7, a support arm 29 is extended from a rotation fulcrum 28, and a presser roller 26 is supported on the working end side of the support arm 29. In this embodiment, two pressing rollers 2G are provided before and after the position where sawing and splitting are performed, and when it is necessary to distinguish between them, they are shown on the exit side, with respect to the insertion direction of the sawn material A, and It will also be explained separately from the entrance side. First, it is necessary for the pressure roller 26 on the entrance side to hold down the sawn material A relatively firmly before starting sawing. Therefore, a biasing cylinder 31 is provided above the support arm 29, so that the exit is always maintained. The pressing roller 26 on the side is strongly pressed down and raised as necessary. On the other hand, since the material A has already been sawed and cracked by the band saw blade 15 on the outlet side presser roller 26, if it is held too firmly, the movement of the band saw blade 15 will be braked and smooth sawing will not be possible. Since it won't work, I'll just use my own weight to hold it down. However, in consideration of the fact that the pressing roller 26 on the exit side must lift up a large amount each time depending on the thickness of the sawn material °A, the lifting chain 33 is actuated by the lifting drive mechanism 32, and the The height at which the press roller 26 on the exit side waits can be set in advance according to the type. These pressing rollers 26
To explain the drive system for this, first, a separate gear is attached to the shaft of the drive sprocket 21 of the conveyor 16, which receives rotation from the conveyor drive motor M2, and a relay gear 35 that meshes with this gear is placed on the side of the conveyor 16. A relay sprocket 36 is provided coaxially with this, and an outlet sprocket 37 is provided at the rotation fulcrum 28 on the outlet side, and a part of the chain 38 is suspended between the relay sprocket 36 and the outlet subrocket 37. Rotation is transmitted to the axis of this rotation fulcrum 2B. As already mentioned, the rotation fulcrum 28 on the presser roller 26 side rises together with the presser roller support frame 27, and the height changes relative to the conveyor 16. The structure is structured so that the 3rd day can always respond to changes. A separate sprocket is installed coaxially with the outlet side sprocket 37 to tension the secondary chain 40, and tension it so as to transmit the rotation to the inlet side sprocket 41, which is coaxial with the rotation fulcrum 28 on the artificial side. do. Then, an outlet chain 42 is further separately stretched from the outlet sprocket 37, and is transmitted to the outlet presser roller sprocket 44 coaxial with the outlet presser roller 26 to drive it. - Rotation is similarly transmitted to the entrance side press roller sprocket 45 by the entrance side chain 43 on the million population side.

The configuration described above is one basic configuration, but
The partition member, which is a characteristic structure of the present invention, can further have the following structure. That is, a partition plate 46 is provided as a partition member in addition to the conveying member, and this plate protrudes from the conveyor 16 at a position that substantially bisects the conveying surface thereof, and is provided along the conveying direction. And the conveyor slant 19 in the conveyor 1'6 has a partition plate 4.
A flange 47 is provided to sandwich the conveyor slats 19, or a groove is provided as shown in FIG. Incidentally, by doing this, it is possible to completely prevent the sawn material A from biting into this part during sawing. Similarly, when an exit roller 49 to which a roller conveyor is applied is provided on the exit side, a flange 50 is also provided in this portion, or a recess 51 is provided in the exit roller so that the uneven engagement with the partition plate 46 is achieved. .

The present invention has a specific configuration as described above, and in order to process the sawn material A, for example, two pieces of sawn material A are separated by partition protrusions 23 or partitions, each of which is a partition member. The plate 46 is arranged as a boundary, and the material is fed forward by the action of the material feeding device 1. In such a case, the band saw blades 15 traveling in the horizontal direction would act to pull each sawn material A sideways, but even if this happens, since there is a partition member between them, This prevents the sawn and split materials A from interfering with each other, allowing smooth sawing and splitting work.

(Effects of the Invention) As described above, the present invention is a non-vertical portable saw machine in which a partition member is provided for the material feeding device.
Even when sawing and splitting two pieces at once, there is no interference between them or irregular shifts during the work, and efficient and highly accurate sawing is possible.
