Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention provides a method for controlling the conveyance posture of thin plates such as veneer veneer, plywood, paperboard, metal plates, synthetic resin plates, etc. intermittently during the conveyance process. The present invention relates to a vibration alignment and conveyance device for thin plates, which automatically aligns conveyance lines by vibrating a ruler belt back and forth.

(B) Prior art In the conventional thin plate aligning and conveying device, a horizontal belt was arranged in the center, and the horizontal belt was movable in the width direction on both sides, and the horizontal oblique angle was set in two stages, making the angle adjustable. A vertical belt device is installed, and a group of small support rollers that can move in the width direction are arranged between the horizontal belt and the vertical belt device to accurately move thin plates such as stainless steel plates, aluminum plates, and glass plates at right angles to the conveying direction. (Jikko Sho 54)
(Refer to Publication No. 9739), or one side of a conveyor for conveying a plate-shaped object is provided with pulleys that rotate in a vertical plane, and upper and lower pulleys that rotate in a horizontal plane are provided on the other side, and each pulley is An endless rope is tied so as to reciprocate on the conveyor in the same vertical plane, and both ends of a pair of operating members provided parallel to the moving direction of the conveyor are connected to each other on the conveyor of the endless rope. is fixed in an upside-down position for reciprocating, both operating members are provided so that they can be guided by two guide rods, and a part of an endless rope is attached so that it can be driven by a drive device, so that the operating member is shaped like a plate. A device in which the center of a plate-shaped object such as a plate glass is aligned with a predetermined position by moving the same distance in opposite directions on both sides of the body is known (see Japanese Patent Publication No. 49-25706).

(C) Problems to be Solved by the Invention However, in the former case of the above-mentioned conventional device, the vertical belt devices disposed on both sides of the horizontal belt touch the cut plate from both sides while the cut plate is being conveyed. Since it is not configured to move back and forth, there is a problem in that the cutting plates that protrude irregularly from side to side cannot be accurately aligned and conveyed perpendicular to the conveyance direction, and in the latter case In this method, an operating member for accurately aligning the plate-like object in the conveying direction moves back and forth relative to both sides of the plate-like object being conveyed by the reciprocating action of an endless rope, thereby aligning the plate-like object accurately in the conveying direction. By clamping the side surfaces, the center line is always aligned at a constant position, so when the plate-shaped body is clamped by the moving member due to frictional resistance with the conveyor, the plate surface is not damaged. An air table must be provided to suspend and support the plate-like body in order to prevent the plate from being damaged.This poses a problem in that the device is complicated and costly, and the operating members are The back-and-forth movement is only a relative movement, and it is not possible to perform alignment work by changing the movement movement for the plate-shaped bodies separately for the left and right sides as necessary, and the position of the plate-shaped bodies cannot be adjusted by performing the above-mentioned movement as quickly as possible. Even if an attempt is made to quickly perform this, there is a limit to how high the speed can be increased because the moving member is driven by the reciprocating motion of an endless rope, and as a result, it is not possible to significantly improve work efficiency. I have a problem.

The present invention solves the above-mentioned problems and provides a vibration alignment and conveyance device for thin plates with extremely high working efficiency, which can quickly and accurately align the thin plates perpendicular to the conveyance direction without damaging them using a simple device. The purpose is to

(d) Means for Solving the Problems In order to solve the above-mentioned problems, the present invention includes a conveyor for conveying thin plates, and a machine on both sides of the conveyor on the carry-in side that is wider than the width of the machine on the unloading side. A pair of ruler belts set upright with the same width as the thin plate,
It is composed of a pair of rotary vane type vibration mechanisms that are inscribed in the ruler side of the ruler belt and vibrate the intermediate portion thereof back and forth intermittently to nearly the width of the machine on the unloading side.

(E) Effect As shown in the first diagram, thin sheets 1 such as veneer veneers discharged from the previous stage, such as a drying process (not shown), are normally irregularly spaced left and right with respect to the conveyor 2 that conveys them. They are often delivered in a conveying posture that protrudes or is slightly bent at an angle.This tendency is especially common for thin plates with a narrow width in the conveying direction, so first align the conveying rows of the parts that protrude irregularly to the left and right. A thin plate 1 is placed on both sides of the conveyor 2 with the machine width Li on the carry-in side.
The part that protrudes irregularly to the left and right is made wider to match the protrusion on the left and right, and is made erect by a pair of ruler belts 3a and 3b with the machine width Lo on the unloading side the same width as the thin plate 1. are gradually pushed inward to align the conveyor rows. However, with only the continuous pushing action of the ruler belts 3a and 3b, the inside of the thin sheet 1 that arrives somewhat obliquely, especially the thin sheet 1 whose width is narrow in the conveying direction as shown in the figure, will be affected by the conveying train that corrects the curvature. Since it is practically impossible to align, the ruler belts 3a and 3b are inscribed on the ruler side, and the machine width Lo on the unloading side is intermittently carried out around the middle part of the ruler belts 3a and 3b.
By driving a pair of rotary vane type vibrating mechanisms 4a, 4b in relation to the ruler belts 3a, 3b, which vibrate back and forth even close to each other, the rotary vane type vibrating mechanisms 4a, 4b vibrate through the rotating shafts 5a, 5b of the rotary vane type vibrating mechanisms 4a, 4b. to rotate the rotary blade bodies 6a, 6b, and rotate the rotary blade bodies 6a, 6b.
The ruler side of the ruler belts 4a, 4b is intermittently pushed inward by rotating a pair of rollers 7a, 7b installed near both ends of the ruler belts 4a, 6b at an appropriate speed, that is, the rotating blades The ruler side of the ruler belts 4a, 4b is intermittently pushed inward by the vibration effect caused by the tapping action of the mold vibration mechanisms 4a, 4b, and the intermediate portion thereof is moved back and forth until it approaches the machine width Lo on the unloading side. By vibrating, the portions that protrude irregularly to the left and right are gradually pushed inward to align the conveyance line, and finally the thin plates 1 are aligned and conveyed so that the conveyance posture is exactly perpendicular to the conveyance direction. It is something to do.

(F) Embodiment Figures 1 and 2 show an embodiment of the present invention. A pair of ruler belts 3a, 3b are set upright with the machine width Lo on the unloading side of the strips being the same width as the thin plate 1, and a pair of ruler belts 3a, 3b are inscribed on the ruler side of the ruler belts 3a, 3b, and the middle part thereof is intermittently A pair of rotary vane type vibration mechanisms 4a, 4 that vibrate back and forth to near the machine width Lo on the unloading side.
It consists of b. Further, the rotary blade type vibration mechanisms 4a, 4b have propeller-like rotary blade bodies 6a, 6b attached to rotary shafts 5a, 5b having an appropriate drive source (not shown), and the rotary blade bodies 6
A pair of rollers 7a each near both ends of a and 6b,
7b is constructed.

Incidentally, the rotary vane type vibration mechanisms 4a and 4b can be freely vibrated alternately by shifting the phase of their vibration period by 90 degrees as shown in the figure, or can be vibrated in the same phase or in an unspecified phase. be.

(g) Effects As explained above, according to the present invention, there is a conveyor for conveying a thin plate, and on both sides of the conveyor, the machine width on the incoming side is wider than the thin plate, and the machine width on the unloading side is set to be the same width as the thin plate. It consists of a pair of upright ruler belts and a pair of rotary vane type vibration mechanisms that are inscribed in the ruler side of the ruler belts and vibrate the middle part of the belt back and forth intermittently up to the width of the machine on the unloading side. Because of this, not only is it possible to align the thin plates during conveyance, in which the conveyance row is disrupted and the sheets protrude irregularly from side to side, but also due to the striking action of the rotary vane-type vibrating mechanism, which was not available in conventional machines. The intermittent vibration action of the ruler belt causes the thin plate being conveyed to be repeatedly pushed inward from the protruding part first, and the conveyed state of the thin plate, which was initially delivered slightly bent at an angle, is gradually conveyed. It is possible to align the sheets so that they are exactly perpendicular to the conveying direction, and there is no need to forcefully press the thin plates 1 with the ruler belts on both sides during the alignment and damage the material. Not only can it fully fulfill its purpose even when using a narrow thin plate, but the phase of the vibration period of the rotary vane type vibration mechanism can be freely changed to the left or right depending on the type of thin plate, so it can be used with many types of thin plates. It can be used for many purposes, and has the effect of allowing work to be done quickly, accurately, and with high efficiency.
