Description

[Detailed Description of the Invention] Technical Field This invention relates to a clipper device, a tenderizing device, a flattening device, and a veneer plywood manufacturing device.
The present invention relates to a veneer loading device installed on the loading side of various veneer veneer processing devices (hereinafter referred to as veneer veneer) such as a drying device or a deposition device.

Prior Art For example, an automatic aligning and feeding device disclosed in Japanese Patent Application Laid-Open No. 52-7568 has a stacking device in which a large number of thin plates are stacked in a predetermined direction, and a stacking device in which a large number of thin plates are stacked at one end of the stacking device. The ruler conveyor is stretched so as to run in a direction perpendicular to the conveyance direction, and is placed above the deposition device, has an axis in a direction perpendicular to the conveyance direction of the thin plate, and rotates toward the ruler conveyor side. A suction conveyance mechanism with a built-in number of feed rolls is arranged vertically in parallel with the axis line perpendicular to the conveyance direction of the thin plate between the suction conveyance mechanism and the ruler conveyor, and a spiral groove is formed on the outer periphery. The thin plate taken out from the stacking device is adsorbed by the suction conveyance mechanism and conveyed to the propulsion conveyor by a feed roll, where it is held between the two. The ruler is taken out by pressing the front end of the thin plate against the ruler conveyor and correcting its position.

However, the above-mentioned pair of upper and lower propulsion conveyors obtains the propulsive force to move the thin plate in the axial direction by sandwiching the thin plate located between them, but when the single plate is sandwiched by this propulsion conveyor, the propulsion conveyor The veneer is deformed by the peaks and valleys of the spiral groove formed on the outer periphery. Since the veneer has low strength in the direction perpendicular to the fibers, the veneer is damaged by being deformed by the peaks and troughs of the spiral groove. I have a problem.

In addition, the above-mentioned pair of upper and lower propulsion conveyors requires setting the distance between them each time depending on the thickness of the thin plates to be aligned, resulting in poor workability.

Furthermore, since the above-mentioned propulsion conveyor is arranged at a location where the axes coincide with each other in the vertical direction, simply holding the thin plate with the propulsion conveyor will not work.
The back end is hanging down. Therefore, even after the thin plate is clamped by the propulsion conveyor,
The rear end of the thin plate must be held, and a suction and conveyance mechanism for this purpose is essential, making the device complex and expensive.

Purpose of the Invention The present invention was invented in order to solve the above-mentioned conventional drawbacks, and its purpose is to reduce the weight of the veneer in a cantilevered state with only the front end of the veneer held in the fiber direction. To provide a veneer loading device that can move the veneer with an optimal force depending on the situation and unload the veneer while taking out the ruler, prevent damage to the veneer, and simplify the device and reduce costs. be.

Composition of the Invention The present invention provides a method for separating a stacked veneer by an appropriate distance from one end in the fiber direction of a stacked veneer stacked on the inlet side of an arbitrary veneer processing device toward the fiber direction in a direction perpendicular to the conveyance direction of the processing device. a ruler device having a ruler surface along the conveyance direction is provided at a position intermediate the ruler surface and one end of the laminated veneer in the fiber direction; a support roll facing toward the direction of transport, and a feed roll including a large number of linear bodies whose free ends are inclined at least toward the conveying direction, one of which is placed upward and the other of which is placed downward;
In addition, the upper one is slightly shifted toward the ruler taking-out device to form a veneer loading device.

Example The present embodiment will be described below with reference to the drawings.

FIG. 2 is a schematic plan view thereof, FIG. 3 is a front view of FIG. 2, and FIGS. 4 and 5 are explanatory diagrams of the feed roll.

The belt conveyor 10 in the figure is included in a veneer processing device (not shown) and consists of two conveyor belts 11a and 11b that are continuously or intermittently driven to convey in a predetermined direction at an appropriate speed. The veneer S moved from the device 20 is carried into the veneer processing device.

The stacked veneers 12 are arranged on the carry-in side of the belt conveyor 10, and a large number of veneers S are stacked with the fiber direction oriented in a direction perpendicular to the conveying direction of the belt conveyor 10. Incidentally, while placing the stacked veneer 12 on a lifter (not shown) that moves up and down,
By sequentially controlling the upward movement as the veneers S are supplied to the carrying-in device 20, which will be described later, it is possible to keep the take-out height of the veneers S substantially constant.

The carry-in device 20 is composed of a ruler taking-out device 13, a feed roll 15, and a support roll 18, and after taking out the ruler while supporting one fiber direction end of the veneer S supplied from the stacked veneer 12, The veneer S is transferred onto the belt conveyor 10.

The ruler device 13 is arranged adjacent to the stacked veneer 12 and at least on the conveyance side of the belt conveyor 10, and has a ruler surface that moves in the direction of the solid line arrow shown in the figure at a substantially synchronized speed along the conveyance direction of the belt conveyor 10. It consists of a ruler belt 14 having a diameter 14a. The ruler device 13 is supplied from the stacked veneer 12, and connects the edge in the fiber direction of the veneer S whose one end in the fiber direction is supported by a feed roll 15 and a support roll 18, which will be described later, and the ruler surface 14a. The veneer S is brought out into a ruler by contact.

The feed roll 15 is disposed between the stacked veneer 12 and the ruler removal device 13, has an axis in the conveyance direction of the belt conveyor 10, and has an axial length extending at least to the input side of the belt conveyor 10, A large number of linear bodies 17 are planted on the outer periphery of a rotating shaft 16 that rotates in the direction of the solid arrow in the figure so that their free ends can contact the lower surface of the veneer S supported by support rolls 18, which will be described later. . The linear body 17 is made of a synthetic resin material or a metal material that is flexible and has excellent corrosion resistance, and has its free end at an appropriate angle θ1 in the conveying direction with respect to the rotating shaft 16. It is installed tilted at an appropriate angle θ2 in the direction of rotation. The angle θ1 is approximately 8 to 30 degrees, and the angle θ2 is approximately 8 to 30 degrees.
is set approximately between 0 and 25 degrees.

The support roll 18 is disposed slightly closer to the ruler plane 14a than the upper position of the feed roll 15, has an axis in the same direction as the feed roll 15, has approximately the same axial length, and rotates in the direction of the solid line arrow in the figure. , one fiber direction end of the veneer S taken out from the stacked veneer 12 in the fiber direction is supported in a cantilever state by the feed roll 15, and as it rotates, the fiber direction end is moved toward the ruler surface 14a side. It is something that draws people in.

Next, the operation of this embodiment will be explained with reference to FIGS. 6 and 7.

As shown in FIG. 6, the operator moves the veneer S taken out from the stacked veneer 12 in the fiber direction, and moves one end of the veneer S in the fiber direction to the feed roll 15, which rotates in the direction indicated by the solid line arrow in the figure. and the support roll 18. Due to this operation, the veneer S is moved by the feed roll 15
and the support roll 18. Since the upper support roll 18 is disposed closer to the ruler bell 14 than the feed roll 15, it is supported in a cantilevered state. When the weight of the veneer S held in a cantilevered state acts on the feed roll 15, the linear body 17 of the feed roll 15 contacts the entire lower surface of the veneer S while elastically deforming according to the weight of the veneer S. Then, a conveying force F in the direction of the solid arrow shown in FIG. 7 is applied.
In addition, a small conveying force is required for light veneers, whereas a large conveying force is required for heavy veneers, so a small conveying force can be obtained for light veneers, and a large conveying force can be obtained for heavy veneers. Therefore, the edge of the veneer S in the fiber direction is brought into contact with the ruler surface 14a moving in the direction of the solid line arrow in the figure, and the veneer S is moved on the belt conveyor 10 while being rulered.
transported to the side. Then, when the cantilever support by the feed roll 15 and the support roll 18 is released in accordance with the above-mentioned conveyance, the veneer S is held on the belt conveyor 10 while the edge in the fiber direction and the ruler surface 14a are kept in contact with each other. After being transferred onto the top, the veneer is carried into the veneer processing apparatus according to the drive. The conveyance force F applied by the feed roll 15 is basically to tilt the free end of the linear body 17 at an appropriate angle θ1 in the conveyance direction of the belt conveyor 10, and to apply the weight of the veneer S to the free end portion of the linear body 17. However, the linear body 1
By further tilting the free end of belt 7 by an appropriate angle θ2 in the rotation direction, a conveying force F inclined in the conveying direction of belt conveyor 10 can be generated.
This contributes to making the feed roll function at a lower rotational speed, and has the effect of significantly reducing wear on the linear body of the roll.

In this way, in this embodiment, the lower feed roll 1
5, the upper support roll 18 is the ruler belt 1
Because it is placed closer to 4, the veneer S brought in
By holding the front end in a cantilever state without holding the rear end in the fiber direction, and pressing the veneer S against the feed roll 15 with a force corresponding to the own weight of the veneer S, the veneer S The front end of the veneer S in the fiber direction is moved by the ruler belt 14 due to the conveying force of the feed roll 15 caused by the linear body 17 being elastically deformed by a force corresponding to its own weight.
It can be carried out while pushing it against the ruler and taking out the ruler.

Thereby, damage to the veneer S in the direction orthogonal to the fibers can be prevented, and the entire device can be simplified and cost reduced.

In this embodiment, one end of the veneer S in the fiber direction is supported in a cantilevered state by the feed roll 15 and the support roll 18, but the veneer S having an elongated width in the fiber direction is When carrying the veneer S into the veneer processing apparatus while taking out the ruler, one end of the veneer S in the fiber direction is supported by the feed roll 15 and the support roll 18, as shown in FIG.
It is also possible to implement a configuration in which the operator carries the veneer into the veneer processing apparatus while supporting the other end in the fiber direction.

Further, the present invention provides a support roll that is a rotating spiral roll with threads formed on the outer periphery, or a roll that is made of a large number of linear bodies whose free ends are inclined at least in the conveyance direction, similar to the feed roll. It is also possible to implement the structure as shown in FIG.

In addition, when the belt conveyor 10 of the veneer processing device is driven to convey continuously or intermittently, the drive type of the carrying-in device of the present invention that corresponds to the case where the belt conveyor 10 of the veneer processing device is driven is basically 10, but may be configured in any format as needed. In addition, when the belt conveyor 10 is stopped, the veneer S on the carrying device is
When stopping, feed roll 15 and support roll 1
By stopping only the ruler belt 14a with a large friction coefficient without stopping the veneer S
It is also possible to interrupt the transport of

Furthermore, in this embodiment, the ruler surface 14a is provided with a ruler dispensing device 13 that can move in the conveying direction, and the belt conveyor 1
Although the fiber direction edge of the veneer S transferred onto the veneer S is kept in contact with the ruler surface 14a, in the present invention, the veneer S is elongated in the transport direction, and one of the fibers in the veneer S is It is also possible to use a non-moving ruler setting device having a ruler surface with excellent smoothness on the side that contacts the directional edge.

Effects of the Invention As explained above, the present invention can be applied from one end in the fiber direction of stacked veneers stacked on the input side of any veneer processing device toward the fiber direction in a direction perpendicular to the conveying direction of the processing device. A ruler device having a ruler surface along the conveying direction is provided at an appropriate distance apart, and the respective axes are set at intermediate positions between the ruler surface and one fiber direction end of the stacked veneer. A support roll oriented in the same direction as the conveyance direction, and a feed roll including a large number of linear bodies whose free ends are inclined at least toward the conveyance direction, one of which is on top and the other is on the bottom, and The one side of the veneer is shifted slightly toward the ruler removal device, and the ruler is removed while being moved with the optimum force depending on the weight of the veneer in a cantilevered state that holds only the end of the veneer in the fiber direction. Thus, it is possible to provide a veneer loading device that can prevent damage to the veneers, simplify the device, and reduce costs.
