The transfer chain is an automatic conveyor, and it can be according to preset route transported substance material, often is used for places such as storehouse, workshop and packing plant. Part of the conveying section of the conveying line needs to rotate the materials by 90 degrees to meet the requirements of the production process, for example, the conveying line on the refrigerator assembly production line needs to rotate the refrigerator direction by 90 degrees.

In the related art, the conveyor line includes a linear transport roller, a roller bracket, a steering strut, and a plurality of steering rollers. The plurality of steering rollers are erected on the roller support at preset angles, and the roller support is arranged above the area where the steering rollers are located. Before the refrigerator enters the area where the steering roller is located from the area where the linear transportation roller is located, the refrigerator is located on one side, close to the steering support rod, of the conveying line, and the refrigerator rotates through a certain angle under the pushing of the steering roller. The one end side of refrigerator collet with turn to the free end butt of branch, the cooperation straight line transports the roller and turns to the promotion of roller, the refrigerator uses the free end that turns to branch to rotate certain angle as the rotation center, realizes turning to. However, when the refrigerator in the related art is turned, the bottom bracket foam of the refrigerator is easily worn, deformed and even damaged under the pulling and squeezing of the advancing force of the linear transportation roller, the turning force of the turning roller and the supporting force of the roller bracket.

Therefore, the embodiment of the disclosure provides a conveying line, which can reduce the force required by material turning, thereby alleviating the phenomena of abrasion, deformation and even damage of the bottom of the material in the turning process.

Referring to fig. 1 and 2, the conveyor line provided in the exemplary embodiment of the present invention includes a roller bracket 100, a steering strut 200, a plurality of linear transport rollers 300, and a plurality of steering rollers 400.

The roller carriage 100 is provided with a linear transport zone 101 and a turning zone 102 in the conveying direction in this order.

Steering strut 200 is disposed in steering zone 102.

A plurality of linear transport rollers 300 are erected in the linear transport area 101, and the linear transport rollers 300 can be driven to rotate so as to push the materials above the linear transport rollers to advance.

A plurality of turning rollers 400 are mounted in the turning area 102 at a predetermined angle, and the turning rollers 400 can be driven to rotate to push the material above the turning rollers to turn.

At least part of the steering roller 400 includes a free rolling portion 401, and the free rolling portion 401 is disposed at one end of the steering roller 400 close to the steering strut 200.

According to the conveying line provided by the embodiment of the disclosure, before the material enters the turning area 102, the material is located on one side of the linear conveying area 101 close to the turning support rod 200, and the linear conveying roller 300 gives forward force to the material to push the material to move continuously into the turning area 102. When the material is in contact with the diverting roller 400, the diverting roller 400 gives a diverting force to the material because the diverting roller is mounted on the roller bracket 100 at a predetermined angle. The material rotates certain angle under the effect of steering force, and the one end of the side of material bottom and steering support rod 200 butt cooperate the promotion of turning to roller 400 and sharp transportation roller 300, and the refrigerator uses steering support rod 200 to rotate certain angle as the center of rotation, realizes turning to. Since at least part of the diverting roller 400 comprises the free rolling part 401, the free rolling part 401 does not give thrust to the material. Therefore, the force center of the material is shifted away from the steering strut 200, as compared to the related art. Because the stress center is far away from the steering support rod 200, the advancing force and the steering force required by steering and the supporting force given to the bottom of the material by the steering support rod are all reduced, so that the phenomena of abrasion, deformation and even damage of the bottom of the material in the steering process are favorably alleviated.

Wherein, the steering roller 400 is erected in the linear transportation area 101 in a preset angle, which means: the diverting roller 400 is at a predetermined angle to the roller bracket 100.

Optionally, the conveyor line that this disclosed embodiment provided is the refrigerator conveyor line, and the material that this disclosed embodiment provided includes the refrigerator, and the bottom of refrigerator is provided with the foam collet.

Alternatively, in connection with fig. 7, the preset angle between the diverting roller 400 and the roller bracket 100 is 20 °. So arranged, the diverting roller 400 imparts a diverting force f to the material ₁ The included angle between the steering force and the roller bracket 100 is 20 degrees, and under the matching of the steering force and the steering support rod, the material can be rotated by 90 degrees, and the steering is finished.

In some embodiments, referring to fig. 2, the roller bracket 100 includes a first roller bracket 103 and a second roller bracket 104, the first roller bracket 103 being provided with a steering strut 200, the second roller bracket 104 being parallel to the first roller bracket 103. The support of the straight transportation roller 300 and the steering roller 400 is facilitated by the arrangement of the first roller bracket 103 and the second roller bracket 104 which are parallel to each other.

Alternatively, the first roller bracket 103 and the second roller bracket 104 are linear, and the first roller bracket 103 and the second roller bracket 104 are parallel to the conveying direction of the material.

In some embodiments, referring to fig. 3, the conveyor line further comprises a pusher 500, the pusher 500 being adapted to push material to the side of the first roller support 103 before the material enters the turnaround area 102. So arranged, it is convenient to turn the material by 90 ° in cooperation with the turning area 102.

Optionally, the conveyor line further comprises a guardrail 600, the guardrail 600 being arranged on the upper side of the first roller bracket 103, and the guardrail 600 covering at least the parts of the first roller bracket 103 located in the straight transportation zone 101 and the turnaround zone 102. By arranging the guardrail at the position, the falling of the materials from the conveying line in the steering process can be avoided.

Optionally, the side of the guard rail 600 facing the second roller bracket 104 is provided with a plurality of rollers 601, the rollers 601 being rotatable in the conveying direction. The pushing device 500 pushes the material to the side of the first roller bracket 103, and the material contacts with the guardrail 600 on the side of the first roller bracket 103. By providing a plurality of rollers 601 on the side of the guardrail 600 facing the second roller bracket 104, the friction between the material and the guardrail 600 can be reduced, making the material easier to push.

In some embodiments, referring to fig. 5, the diverting roller 400 comprises a first shaft 402 and a stationary cylinder 403. The first shaft 402 is rotatably connected to the roller bracket 100. The fixed cylinder 403 is sleeved on the first shaft 402, and the fixed cylinder 403 is fixed relative to the first shaft 402. Thus, the first shaft 402 is driven to rotate to drive the fixed cylinder 403 to rotate, so as to push the material on the fixed cylinder 403 to move.

Alternatively, the fixed cylinder 403 and the first shaft 402 are connected by welding. In this way, the relative fixation between the fixed cylinder 403 and the first shaft 402 can be achieved at a low cost.

In some embodiments, referring to fig. 5, where the steering roller 400 includes a free rolling portion 401, a stationary cylinder 403 is sleeved over an end of the first shaft 402 distal from the steering strut 200. The turning roller 400 further includes a free-rolling cylinder 404, the free-rolling cylinder 404 is sleeved on an end of the first shaft 402 close to the turning strut, and the free-rolling cylinder can freely rotate around the first shaft. Thus, the first shaft rod 402 can drive the fixed cylinder 403 to rotate, provide a steering force for materials, and provide support for the free rolling cylinder 404, so that the forced center of the materials moves outwards, and the advancing force, the steering force and the supporting force required by the steering of the materials are reduced.

In some embodiments, with reference to fig. 3 and 4, in the case where the material is not diverted, the first side 10 of the material faces the downstream side in the conveying direction, and the ratio of the length n of the free rolling portion (also the length n of the free rolling cylinder 404) to the length m of the first side ranges from n/m =1/2 to 3/4.

The longer the free rolling cylinder 404 is, the larger the contact area between the material and the free rolling cylinder 404 is, and the smaller the contact area between the material and the fixed cylinder 403 is, which is more beneficial to moving the stressed center of the material outwards in the direction away from the steering support rod 200, and the smaller the force required by the material to steer. However, the contact area of the material with the fixed cylinder 403 is small, which may cause the material to receive a small steering force from the fixed cylinder 403, and the material may be difficult to steer if the steering force is too small. By controlling the ratio of n to m in the range, the stress center of the material can be moved outwards reasonably, the force required by material steering is reduced properly, the material can be ensured to be subjected to enough steering force, and the material can be ensured to steer smoothly. If n is larger than m, the front sides of the materials are all positioned above the free rolling cylinder 404, and the materials cannot smoothly turn; if n is too small, the force required to divert the material is large, easily resulting in damage to the bottom of the material. Here, the force required for the steering of the material includes a forward force, a steering force, and a supporting force.

Illustratively, n/m may be 0.5, 0.55, 0.6, 0.65, 0.7, 0.72, 0.73, 0.75, or the like.

In some embodiments, with reference to fig. 3 and 4, the material further comprises a second side 20 perpendicular to the first side 10, the second side 20 being directed towards the downstream side of the conveying direction in case the diversion of the material is completed; the ratio of the span b of the region where the free rolling part is located (also the span b of the region where the rolling cylinder is located) to the length k of the second side surface ranges from b/k =1/3 to 1/2.

If b is too large, the contact area between the material and the linear transportation roller 300 is too small, which results in too small advancing force applied to the material and is not beneficial to the steering of the material. If b is too small, the material cannot turn through the desired angle before it contacts the steering strut 200, again adversely affecting the steering of the material. By limiting the ratio of b to k to the above range, it is ensured that the material is subjected to a sufficient advancing force, turning through 90 ° according to a preset path.

In some embodiments, in the case that the steering roller 400 includes the free rolling portion 401, the steering roller further includes a plurality of bearings 405, the plurality of bearings 405 are sleeved on the first shaft 402, and the bearings 405 are used for connecting the first shaft 402 and the free rolling cylinder 404, so that the free rolling cylinder 404 can freely rotate around the first shaft 402. The friction force between the free rolling cylinder 404 and the first shaft rod 402 can be reduced by arranging the bearing 405, the resistance of the free rolling part 401 to the material is reduced, and the forward force required by the forward movement of the material is favorably reduced.

In some embodiments, turning strut 200 is perpendicular to roller bracket 100, turning strut 200 including an attachment end 201 and a turning end 202, attachment end 201 for fixed attachment to roller bracket 100, turning end 202 for abutment with first side 10 of material to assist in turning the material, see fig. 6. The turning end 202 is abutted against one side of the first side surface 10 close to the turning support rod 200, so that the material can rotate by taking the turning end 202 as a rotation center, and the turning of the material is realized.

Optionally, the diverting end 202 of the diverting strut 200 is further provided with a roller 203, the roller 203 being able to turn in the conveying direction. Therefore, the friction force between the steering support rod 200 and the material can be reduced, and the material can be smoothly steered.

In some embodiments, the length of the steering strut 200 ranges from 30mm to 60mm. For example, the length of the steering strut 200 may be 30mm, 35mm, 40mm, 45mm, 50mm, 60mm, or the like. The turning end 202 of the turning support rod 200 is the rotation center of the material, and if the turning support rod 200 is too long, the distance between the rotation center and the stress center of the material is shortened, so that the acting force required by the material turning is increased, and the material is abraded. If the length of the steering strut 200 is set too small, it can cause the first side 10 to disengage from the steering end 202, resulting in a steering failure. Therefore, the length of the steering support rod 200 is limited in the range, so that the phenomenon of material bottom damage is favorably relieved, and the steering is favorably and smoothly carried out.

In some embodiments, referring to FIG. 3, the first side 10 includes a first side 11 adjacent to the steering strut, the abutting position of the steering end 202 against the first side 10 is a first position, and the distance between the first position and the first side 11 is 1/20-1/8 of the length m of the first side. For example, the distance between the first position and the first side edge 11 is 0.05, 0.07, 0.09, 0.10, 0.12, 0.125, or the like of the length of the first side surface. The first position corresponds to the rotation center of the material, and if the distance between the first position and the first side 11 is too long, the distance between the rotation center and the stress center of the material is shortened, so that the acting force required by the material to turn is increased, and the material is abraded. If the distance between the first position and the first side edge 11 is set too small, the first side edge 10 may be separated from the turning end 202, resulting in a failed turning. Therefore, the distance between the first position and the first side edge 11 is limited in the range, so that the phenomenon of material bottom damage can be relieved, and the steering can be smoothly performed.

In some embodiments, referring to fig. 6, first shaft 402 is provided with first gear 4021 and second gear 4022 at both ends, and first gear 4021 and second gear 4022 are both perpendicular to first shaft 402. The conveying line further comprises a plurality of chains 4023, and the plurality of chains 4023 are used for connecting the first gear 4021 and the second gear 4022 of two adjacent first shafts 402 to realize the linkage of the plurality of first shafts 402. By the arrangement, the linkage of the first shafts 402 can be realized, and the synchronous operation of the steering rollers 400 can be driven by one motor, so that the materials can be steered by 90 degrees.

Alternatively, the steering roller 400 includes a first steering roller located at the first end side of the steering zone 102, the first gear 4021 or the second gear 4022 of the first steering roller is connected to the second gear 4022 or the first gear 4021 of the adjacent steering roller 400 by a chain 4023, and the other gear of the first steering roller is connected to the motor by a chain. Therefore, all the steering rollers can be driven to synchronously rotate by one motor, and cost is saved.

FIG. 7 is a force diagram o of the bottom of the material of the conveyor line provided by an embodiment of the disclosure ₁ Is the first stress center, f ₁ The bottom of the material is subjected to the steering force of the steering roller 400, f ₂ The bottom of the material is subjected to the driving force of the linear transport roller 300, f ₃ Is a supporting force of the steering column 200. FIG. 8 is a force diagram of the bottom of the material in a related art conveyor line, o ₂ Is the second stress center, f ₄ The bottom of the material is subjected to the steering force of the steering roller, f ₅ The bottom of the material is driven by a linear conveying roller f ₃ The supporting force of the steering support rod.

In the conveying line in the embodiment of the disclosure, for the part of the material located in the turning region 102, the free rolling part 401 does not give thrust to the material, and the side of the material far away from the turning strut 200 is stressed. Therefore, the center of force o of the material is compared with the related art ₁ Biased away from the steering strut 200. Since the center of force is far from the steering strut 200, the forward force and the steering force required for steering are both reduced according to the lever theorem, and accordingly, the supporting force given to the bottom of the material by the steering strut is both reduced. Therefore, the abrasion, deformation and even damage of the bottom of the material in the steering process can be relieved. Meanwhile, the power required by the motor is correspondingly reduced, and the reduction of energy consumption is facilitated.
