Detailed Description

Referring to fig. 1 to 5, a roller conveyor centering device comprises a rack and rollers 2 arranged on the rack in rows, wherein fluent strips 3 are arranged between part or all of the adjacent rollers 2, a jacking mechanism 5 for adjusting the tops of the fluent strips 3 to be higher or lower than the tops of the rollers 2 is arranged at the bottom of each fluent strip 3, guardrails 4 which are higher than the rollers 2 and vertical to different surfaces of the rollers 2 are arranged on two sides of the rack, and the guardrails 4 are connected with a translation mechanism for driving the guardrails 4 on the two sides to move towards or away from each other.

When the plank passes through the utility model discloses a cylinder conveyer is during device placed in the middle, climbing mechanism 5 jack-up fluent strip 3 makes fluent strip 3's top be higher than cylinder 2's top, utilizes fluent strip frame 3 to play the plank, makes the plank unsettled for cylinder 2, then 4 relative motions of guardrail of translation mechanism drive both sides, the crooked plank of guardrail 4 correction to clip the plank and make the plank center. Subsequently, the guardrails 4 move away from each other, the fluency strips descend, the roller conveyor continues to convey the wood boards, and the circulation is carried out, so that the labor can be saved. Because circulation at every turn all makes 4 tight after the certain time of clamp of guardrail open, so the utility model discloses can be applicable to the plank of multiple width, fluent 3 has erect the plank and has except can making things convenient for the plank to the both sides motion of rolling conveyer, can also produce the braking on the direction of transfer to the plank, makes the plank slow down, and is static even, avoids plank and guardrail collision overstimulation to lead to plank surface to produce flaw or the guardrail is hit the damage by the plank.

It should be noted that the fluency strip 3 should be a fluency strip using casters, with the swivel axes of the casters orthogonal to the drum 2, whereas a fluency strip with swivel axes of the casters parallel to the drum 2 is not available. If the universal wheels or the smooth strips of the balls are adopted, the centering process can be smoother, but the universal smooth strips cannot brake the wood board, so that the collision between the wood board and the guardrail 4 is strengthened, and the universal smooth strips are not recommended.

The rack comprises a supporting leg 1, a side plate 11 connected to the top end of the supporting leg 1 and a bottom plate 12 connected to the bottom of the side plate 11, and two ends of the roller 2 are respectively connected with one side plate 11 in a rotating mode. The base plate 12 may be divided into a plurality of pieces as shown, or may be connected into a single piece. Climbing mechanism 5 sets up in the frame, can be cylinder, pneumatic cylinder or electric putter, and concrete mounted position has following three kinds:

the jacking mechanisms 5 are vertically connected between the top surface of the bottom plate 12 and the bottoms of the fluency strips 3, and each fluency strip 3 is provided with at least two jacking mechanisms 5. This mode uses more cylinders, and difficult synchronization, does not recommend.

Two, every the bottom of fluent strip 3 is provided with two piece at least support montant 31, many support montant 31 and connect a connecting plate jointly, climbing mechanism 5 is vertical to be connected bottom plate 12 top surface with between the connecting plate bottom.

Thirdly, every the bottom of fluent strip 3 is provided with two piece at least support montant 31, many support montant 31 and divide into two sets ofly, and every group connects a crossbeam 32 jointly, climbing mechanism 5 is vertical to be connected bottom plate 12 top surface with between crossbeam 32 bottom, every crossbeam 32 is furnished with two at least climbing mechanism 5.

The second scheme and the third scheme are respectively good and bad, the second scheme is equivalent to the third scheme that the cross beams 32 are connected into a whole, the minimum number of cylinders can be used, the synchronization is easiest, but the whole machine is heavier, and the wood chips which are shaken are easily accumulated on the top surface of the connecting plate. The third scheme is the scheme shown in the figure, the jacking mechanism is formed by at least four cylinders and is easy to synchronize, and if the connection mode of the output end of the jacking mechanism and the cross beam 32 is changed into hinging, the fluent strip can be inclined and can be modified to be close to the edge instead of being centered.

The specific structure of the translation mechanism is as follows, the translation mechanism comprises two slide rails 64 vertically connected between two side plates 11, two rotating rods 62 rotatably arranged on the side plates 11, sliding blocks 61 slidably connected on the slide rails 64, a belt 63 forming a loop by bypassing the two rotating rods 62, and a driving member for driving the belt to move bidirectionally, one rotating rod 62 is arranged on each side plate 11 in the same direction, two sliding blocks 61 are arranged on each slide rail 64, each of the two sliding blocks 61 on the same slide rail 64 is connected with one guard rail 4, one of the sliding blocks 61 is connected with the upper section of the loop formed by the belt 63 (see fig. 2), and the other sliding block 61 is connected with the lower section of the loop formed by the belt (see fig. 4). When the driving member drives the belt 63 to rotate, the two sliding blocks 61 on the same sliding rail 64 can move towards or away from each other, so as to realize the facing or the separating of the guardrails 4. Preferably, a protective cover 65 may be provided where the belt 63 passes around the rotating rod 62.

The drive member may be a bi-directional motor with an output end driven to a belt 63. Or the stretching cylinder 6 is vertically connected between two guardrails 4, the stretching cylinder 6 is positioned between two slide rails 64, the guardrail 4 is directly pushed by the cylinder, and the slide rails 64 and the sliding blocks 61 are only used for assisting the synchronization of the guardrails 4 on two sides. As shown in the figure, the stretching cylinder 6 is arranged on the bottom plate 12, and only the output end of the stretching cylinder 6 is hinged with one side guardrail 4.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and decorations can be made without departing from the principle of the invention, and these modifications and decorations are also regarded as the protection scope of the present invention.
