Abstract

PURPOSE:To surely perform delivery by providing a means individually controlling right and left conveyers by a condition of material wood on the conveyer and a means forming a V-shaped receiving part protruding on the conveyer inhibiting the delivery of the material wood, in the case of a device which delivers the material wood being placed in an orthogonal direction with the axial core to the next process. CONSTITUTION:A material wood 1, fed from the preceding stage, is detected on a log hole conveyer 2 by a selection detector 8 for whether or not the material wood is suited for specification, and unsuited material wood is rejected. When the material wood is suited, the second receiving frame 14 is swiveled to the upper by a fluid cylinder 15, forming a receiving surface 18 of up gradient in the conveying direction. And the material wood 1 is fed into a conveyer 7. Here the material wood 1 is detected for its diameter by a diameter detector 19, adjusting a gradient angle of the second receiving frame 14. While the material wood 1 is detected for its condition by a detecting condition of a pair of right and left confirmation detectors 10, properly arranging the attitude by individually controlling right and left conveyers. When the material wood 1 is adapted to the receiving frame 14, the first receiving frame 11 of down gradient in the conveying direction is moved to the upper, and the material wood is held between the first and second receiving frame, being prevented from delivery. In this way, the material wood can be surely delivered one by one.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention is directed to the use of log centering devices, veneer laces, sawmills, etc., for the purpose of handling logs conveyed on a conveyor in a direction perpendicular to the axial direction of the conveyor from the previous stage. To the next process such as wood removal equipment,
The present invention relates to a device that reliably dispenses one bottle according to its processing capacity.

``Prior Art'' Conventionally, this type of device has been equipped with a pair of kick-out pieces on the left and right that are configured to be able to move in and out of the conveyor surface at an intermediate position of the conveyor. This kick-out piece was made to protrude from the conveyance surface, and while the raw wood conveyed from the previous stage was kept on the conveyor, it was fed out to the book. A pair of letter-shaped or arc-shaped pedestals are installed on the left and right so that they can swing freely, and in response to instructions from the next process, the logs to be fed are temporarily transferred onto these pedestals, and the pedestals are swung. He was pulling out logs destined for books.

[Problem to be Solved by the Invention] However, in these conventional techniques, the raw wood that has been transported from the previous stage process, or that has been transported and is stored in multiple pieces on a conveyor, is sent to the next stage processing process all at once. It was impossible to reliably send it to the book address.

In other words, with the former kick-out piece, if the logs were to be transported onto the conveyor, due to the mechanism in which the kick-out pieces protrude from the top of the conveyor at the same time on the left side, the rear part of the log in the longitudinal direction For example,
Even if one intervenes at the rear of one longitudinal side, and the other intervenes at the lower part of the female side in the longitudinal direction and kicks one longitudinal side of the log forward, the pond side part will be lifted up. It turns out. In addition, if the amount of logs transported from the previous process exceeds the amount processed in the next process, multiple logs will be stored on the conveyor, but between the groups of logs in this storage state, When the kicking piece is protruded to kick out one log forward, there are cases where not only one log but two logs are kicked out at the same time, and this tendency is especially true when the logs are stored with a mixture of large and small diameters. Often seen.

Also, in the latter pedestal method, as in the former case,
In the past, logs that had been transported would fall during transfer, and it was difficult to transfer them one by one from among groups of logs in storage.

However, the points common to both methods are that the kick-out pieces or cradle that protrude from the conveyance surface also serve as a stop for the subsequent logs, and that they do not correspond to the size of the log diameter. be.

"Means for Solving the Problems" In view of the above, the present invention confirms the presence of logs conveyed perpendicularly to the axial direction at an arbitrary position of a pair of left and right conveyors, and rotates the left and right conveyors separately. A log confirmation detector is installed to control the drive system for transporting logs, and a receiving surface on which logs are placed at each upper limit is installed near each pair of left and right conveyors, with the phase shifted in the direction orthogonal to the conveyance direction. It is composed of a first receiving frame having a downward slope with respect to the conveyance direction and a second receiving frame having an upward slope with respect to the conveyance direction, and is capable of moving in and out of the conveyance surface of each of the conveyors separately, This ensures that the logs are sent to the next stage of processing.

``Embodiment'' Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings, starting with the configuration.

Log hole conveyor 2 that conveys raw wood 1 from the previous stage process
A conveyor 7 is constructed by supporting chain wheels 5 on bearings 4 installed on a frame 3 at regular intervals in the front and back, and a chain wheel 6 suspended between the chain wheels 5. ? 1. A pair of left and right units are installed perpendicular to the feeding direction.

At the end of the log hole conveyor 2, a phototube, a proximity switch,
A log sorting detector 8 consisting of a limit switch and the like is installed to control the driving and stopping of the log hole conveyor 2 9 Further, a separate prime mover 9 is installed for each pair of conveyors 7, and a separate prime mover 9 is installed for each conveyor 7. The drive system of each conveyor 7 is controlled by a command from a log confirmation detector 10, which is composed of a phototube, a proximity switch, a limit switch, etc. arranged near the terminal end, and the left and right conveyors are driven and stopped individually.

On the outside perpendicular to the conveyance direction of each conveyor 7, a rectangular first receiving frame 11 whose rear end is vertical and whose upper surface slopes downward with respect to the conveyance direction is pivoted to the lower part of the front frame 3. The piston rod 13 of the fluid cylinder 12 is connected to the piston rod 13 of the fluid cylinder 12, and can be moved up and down relative to the conveying surface. Also,
The phase of the first receiving frame 11 is shifted in the direction perpendicular to the transport direction, and one corner of the rectangular second receiving frame 14 is attached to the lower part of the rear pedestal 3 so that the upper surface thereof has an upward slope. At the same time, the other corner of the fluid cylinder 15 is connected to the screw rod 16 of the pivoted fluid cylinder 15, and the other corner is brought into contact with a pin 17 on the pedestal 3, and the swinging movement using the contact point of this pin 17 as a fulcrum causes it to move against the conveying surface. It can appear at will. Therefore, when the first receiving frame 11 and the second receiving frame 14 are at their upper limits, the upper surfaces thereof constitute a receiving surface 18 having a substantially V-shaped cross section on which the log 1 is placed.

On the other hand, at appropriate positions above each conveyor 7, photocells, proximity switches, One log diameter detector consisting of a scanner or the like is installed, which detects the log diameter stepwise or steplessly, and detects the expansion and contraction amount of the piston rod 16 of the fluid cylinder 15 connected to the second receiving frame 14 stepwise or steplessly. Controlled steplessly.

Further, on the outside of each of the first receiving frame 11 and the second receiving frame 14 arranged on the left and right pairs, a pin 20 on the pedestal 3 is provided.
A push arm 23 is connected to the contact point as a pivot point via a piston rod 22 of a fluid cylinder 21 pivotally supported on the pedestal 3, and the push arm 23 can move in and out in a direction perpendicular to the conveying direction. .

In the figure, reference numeral 24 is a relay conveyor that is connected to each conveyor 7 and conveys the raw wood 1 to a processing device for the next step.

Next, the effect will be explained.

First, the logs 1 conveyed from the previous stage process are placed on the log hall conveyor 2. At this time, the logs are transported from the log hall conveyor 2 onto the conveyor 7 by the log sorting detector 8. If it is detected that the diameter, specifications, etc. of the log hole conveyor 2 do not match in the processing equipment of the next step, the drive of the log hole conveyor 2 is stopped and the log is discharged. Next, by extending the screw 1-rod 16 of the fluid cylinder 15, the second receiving frame 14 is swung upward using the contact point of the pin 17 as a fulcrum, projecting from the conveyance surface, and with its upper surface facing the conveyance direction. The slope is uphill.

Under this condition, the logs 1 are transferred to the conveyor 7 by synchronously driving the separate prime movers 9 for the pair of left and right conveyors 7.
The material is transported forward from the starting end.

The log diameter detector 19 detects the diameter of the log 1 in the process of being conveyed, for example, in stages such as 2 or 3 steps, or in a non-step manner.
Piston rod 16 of fluid cylinder 15 connected to 4
Adjust the amount of expansion/contraction and set the slope angle of the upper surface of the second receiving frame 14.9 Also, if the logs 1 are being conveyed parallel to the axial direction during transportation, check the logs installed on the left and right pairs. The detector 10 simultaneously detects the outer circumferential portion of the log 1 on both the left and right sides and stops each prime mover 9.

Furthermore, if one of the logs 1 is detected by the log confirmation detector 10 because the logs 1 are conveyed in an offset manner, for example, the right side in the conveyance direction will be detected by the log confirmation detector 10 located on the right side. Then, the right prime mover 9 is controlled, and the right conveyor 7 is first stopped, and the left conveyor 7 is activated when the left side of the log 1 is detected by the log confirmation detector 10 located on the left side. The log 1 is stopped, and the log 1 is positioned in front of the second receiving frame 14 with its axis substantially perpendicular to the conveying direction.

Next, by extending the piston rod 13 of the fluid cylinder 12, the first receiving frame 11 is made to protrude from the conveying surface, and the log 1 is lifted from the pair of left and right conveyors 7.
The cross sections formed by the upper surfaces of the receiving frame 11 and the second receiving frame 14 are placed on a substantially V-shaped receiving surface 18. At this time, if the amount of logs 1 supplied from the previous stage process is large compared to the processing capacity of the next stage processing process, and if a plurality of logs 1 are stored and waiting on the conveyor 7, the first receiving frame When the log 11 is raised, the vertical portion at the rear end prevents the adjacent log 1 from being drawn out.

A pushing arm 23 intervenes equidistantly on the 100-end face of the log 1 placed on the upper surface of each of the first receiving frame 11 and the second receiving frame 14 by fluid movement using the contact point of the pin 20 as a fulcrum. is centered on the pair of conveyors 7, and then the second
The receiving frame 14 is swung back to below the conveying surface. By this swinging return, the log 1 slides down from the downwardly sloped surface of the first receiving frame 11 and is delivered to the starting end of the relay conveyor 24, and is conveyed by the rotation of the relay conveyor 24 to the next J'2 I culm.

``Effects'' As described above, according to the device of the present invention, the presence of logs conveyed perpendicularly to the axial direction at arbitrary positions on the left and right conveyors is confirmed, and the left and right conveyors are rotated separately. Install a log confirmation detector to control the drive system.2. At a position near each of the left pair of conveyors, there are first receiving frames whose receiving surfaces on which logs are placed at each upper limit have a downward slope with respect to the conveying direction, with the phase shifted in a direction perpendicular to the conveying direction. and a second receiving frame having a slope of 11 degrees with respect to the conveyance direction, and can be moved in and out of the conveyance surface of each conveyor individually, so that the disadvantages of the conventional method described above are solved. According to the 98 processing steps of the next stage, the logs destined for - books can be reliably delivered from the logs transported from the previous stage process or from the group of logs waiting to be stored.

In addition, by adjusting the upward slope angle of the second receiving frame that forms the receiving surface of the log using the log diameter detector and changing the obtuse angle of the receiving surface that is formed by the first receiving frame, the diameter can be adjusted to a wide range of sizes. Even from a group of mixed logs, it is possible to accurately lift and feed the logs to the book.9
