Description

Conveyor for Conveying Packages at Curves

The present invention relates to a belt conveying conveyor for easily transporting a package in a curved portion, and more particularly, in a curved portion to easily transport the package even in a curved section in which the transport path is curved. It relates to a conveyance conveyor of the package.

In general, the conveyer conveying device 200 is a facility for transporting the package in a linear direction, as shown in Figure 1, the carrier belt 210 on which the package is loaded and a carrier roller 212 below, And a return roller 214 at the lower portion thereof and a roller stand 220 supporting them, which transmits power to the belt 210 to rotate the belt in an endless track, a reducer, and The pulley etc. are equipped.

However, such a conveyor 200 may be conveyed as two straight conveyors 200 when the conveyance is only a straight line and the conveyance position is not a straight line, as shown in FIG. 2A). As shown, a curved conveyance conveyor 240 named Pipe Conveyor, or Curved Conveyor, should be used.

In the curved conveyance conveyor 240, the pipe conveyor (Pipe Conveyor) is a device for conveying the package by rolling the belt round like a pipe by a special roller structure to be supported by the drive rollers, the structure is complicated and the transport amount It is a small amount, and even in the straight part, the belt conveyor and the support rollers of the pipe conveyor have to be a special pipe-type structure, expensive equipment is required.

And, the curved conveyor 250 is belt 258 by a separate independent roller stand 256 rotatably mounted as a hinge 254 at the bottom of the structural steel 252, as shown in FIG. Since the package is loaded and transported above, the centrifugal force generated at the curved portion and the semi-centrifugal force caused by the folding of the belt allow the roller stand 256 to freely swing, and the upper portion of the roller stand 256 is avoided. Pivot hinge 254 structure is made by adjusting the centrifugal force and the anti-centrifugal force while driving the curved portion is a principle that the belt 258 rolls on the roller 260 to balance.

However, the problem of the conventional curved conveyor apparatus 250 as described above, First, the size of the frame of the roller stand 256 in the cargo transport should be precisely designed by the radius of rotation of the curved portion, the speed of the package, the amount of transport, etc. However, it is difficult to determine each mechanical element according to the actual operating conditions such as friction and temperature only by the theoretical design calculation. Therefore, the structure is corrected by empirical experimental value.

That is, the rotation radius that is not appropriate in the radius of rotation of the curved portion is inappropriately fixed to the carrier roller 260 and the return roller 262 position integrally with each other so that the belt 258 and the carrier roller 260 in the curved portion is completely Because they are not in close contact, the resulting centrifugal and semicentrifugal forces are not properly controlled. In addition, the carrier roller 260 and the return roller 262 are fixed to the roller stand 256, respectively, so that the belt 258 cannot be adjusted like the belt meander adjustment by the adjustment of the rollers 260 and 262. Accordingly, the roller stand 256 is excessively swinged upwards, so that the carrier roller 260 and the return roller 262 are rotated in the same manner, thereby increasing the swing width and limiting the amount of cargo carried on the belt 258. Will receive.

In particular, the swing radius should be adjusted slightly in response to the change of the carrying amount and the change of the driving speed (high speed, low speed), but the size of the roller stand 256 is fixed around the rotating hinge axis 254 of the upper end, so the swing radius This is fixed and constrained by the use of the conveyor 250.

Second, since the carrier and the return roller stand 256 are composed of separate stand frames and connected together, the facility structure is complicated, and the empty return belt on the return side compared to the centrifugal force generated by the belt 258 and the cargo 270. Since the centrifugal force generated by 272 is relatively small, in the case of the integrated roller stand 256 as described above, the phenomenon of reducing the centrifugal force on the carrier belt 258 side cannot be used.

Third, the roller stand 256 and the rollers 260 and 262 are fixed in the through-connect type, when replacing the rollers 260 and 262, all the stand 256 must be replaced. Therefore, the maintenance cost and manufacturing cost are increased, and the hinge 254 structure at the top of the roller stand 256 is free to rotate in the rotational direction, but cannot support the force against the acceleration force generated in the transport direction of the carrier belt 258. It is a fragile structure and difficult to use in parallel with a conventional conveyor frame even when transporting a package in a straight portion.

The present invention has been made to solve the above-mentioned conventional problems, the object of which is to improve the convenience of smooth conveyance and roller replacement in the curved portion, improved by reducing the equipment cost and operation maintenance cost by having a simple structure The present invention provides a conveyor apparatus for conveying a package at a curved portion.

Equipped with rollers, the carrier belt 32 is provided with an upper stand 35 for sliding, and the upper stand 35 is slided along the guide rail 15 when the carrier belt 32 receives a centrifugal force. As the guide rail 15, the plurality of side carrier rollers 37 and the central carrier rollers 39 are assembled and installed on the integrated upper stand 35 having the same arc-shaped cross-sectional structure as the guide rail 15, and the upper stand ( 35) The bearing attachment wheel 40 mounted on the side surface is moved while swinging along the guide groove 20a formed in the longitudinal direction on both sides of the space 20 of the guide rail 15 while supporting the upper stand 35. .

As shown in FIG. 5, the integrated upper stand 35 has a lower arc shape and a curved arc shape in which both ends thereof rise, and the upper flange 45 constituting the stand 35 body may be assembled with the side carrier roller 37. There are two bolt holes 37b at the top so that the other side has holes 37c at the side so that the roller shaft can be moved by the hinge structure. In addition, two bolt holes 39d are provided on the upper and lower sides of the roller 39 so as to be assembled with the central carrier roller 39.

On the side of the upper stand 35, there are three wheels 40 and mounting holes 40h for swinging the upper stand 35 along the guide rail 15, and the wheel 40 with bearings there is a bearing 40c. Is rotatably inserted through each, the outer cover 41 of the wheel 40 is configured to rotate in contact with the guide groove (20a) of the inner surface of the guide rail (15).

In addition, the diameter of the wheel 40 is smaller than the width of the guide rail 15 is mounted so that the wheel 40 is rotatable along the rotation radius while moving freely in the guide groove (20a) of the guide rail (15).

In addition, the hinge shaft 52 and the hinge bar 54 are positioned at both sides of the upper stand 35 so as to be assembled with the return side roller lower stand 60 so as to be rotatable to the lower stand 60. Will be.

In addition, as shown in FIG. 6, the side carrier roller 37 is rotatable about the shaft 37a, and the shaft 37a adjusts the angle with the shaft 37b on the left side moving up and down so that the height can be adjusted. It is a shaft 37c for this purpose. A support body 37d is mounted on the upper side of the left shaft 37b so that the height can be adjusted. A hole 37d 'is formed at the center of the support body 37d, and on the left shaft 37b. The height adjustment bolt 37f is fixed to the upper side, and the height adjustment bolt 37f passes through the hole of the support body 37d and is coupled to the nut 37e at the upper portion of the support body, thereby adjusting the height of the nut 37e. It is controlled by. And, the support body (37d) is fixed to the bolt so that it can be assembled with the upper flange (45).

Then, the right shaft 37c of the side carrier roller 37 has a pin 37j in the left and right holes 37c 'of the shaft 37c so that only the angle can be adjusted, and the hole of the sleeve 37l and the shaft 37c. It is connected through 37c 'and is fixed by the split pin 37k.

In addition, the side carrier roller 37 has a belt departure prevention jaw 37m so as not to be released when the belt 32 is excessively tilted to one side. The left and right sides are the same, and the side return roller 82 on the return roller part 80 side has the same structure.

On the other hand, as shown in Figure 7, in the roller shaft 39b of the central carrier roller 39, the fixing cover 39c and the bolt 39d are bolt holes 39e of the integrated upper stand 35 without a separate hole. Connected to and assembled.

And, in the longitudinal direction of the guide rail 15 as a hinge axis 52 and the hinge bar 54 on the lower side of the upper stand 35 of the carrier roller portion 30 at the lower side of the guide rail 15. Rotatably connected, the upper surface is provided with a lower stand 72 having a plurality of rollers to allow the return belt 70 to slide, and the lower stand 72 is movable independently of the upper stand 35. The return roller part 80 is positioned, and the return roller part 80 is disposed on the lower stand 72 so as to face the plurality of side return rollers 82 and is rotatably mounted to slide the return belt 70. It is possible to support it.

Hereinafter, the operation and effects of the present invention will be described.

As shown in Fig. 4, the integrated roller upper stand 35 is installed in the radial direction at the center of the arc that forms the curved portion at the curved portion. In the upper stand 35, the return roller lower stand 72 is assembled by the hinge shaft 52 and the hinge bar 54, and the magnitude of the centrifugal force generated on the carrier belt 32 side and the return belt 70 side. Is differently assembled so as to move properly by the centrifugal force generated in each, and the bearing attachment wheel 40 mounted on the side surface of the upper stand 35 is inserted into the guide rail 15 while supporting the upper stand 35. Afterwards, the carrier belt 32 side is interfered during the swing by the return belt 70 side, and as a result, only the total centrifugal force can swing, so that the conveyance can be conveyed while representing the centrifugal force generated by the curved portion as the swing movement. Will be.

In addition, the side roller roller 37 and the central carrier roller 39 are assembled on the integrated roller upper stand 35, and the return roller lower stand 72 is assembled in an integral manner, and thus, the frictional force of the belts 32 and 70 is caused. Acceleration force in the belt advancing direction cancels each other (carrier, return side), and the centrifugal force of the belt 32 and the package generated at the curved portion is forced to the anti-centrifugal force by friction of the belt 32 and the rollers 37 and 39. Since the height of the side rollers 37 and the end jaw 37m is adjusted so that the centrifugal force is canceled from each other, only the smallest centrifugal force is generated in the integrated roller upper stand 35 so that the size of the upper stand 35 and the guide rail 15 is reduced. Can be reduced.

In addition, the device can be used in a curved section by connecting to a frame of a conventional straight conveyor.

Then, the left shaft 37b of the side carrier rollers 37 and 82 of the carrier roller part 30 and the return roller part 80 controls the height by turning the nut 37e at the height adjustment bolt 37f. The angle is adjusted due to the right shaft 37c. In addition, the carrier rollers 37 and 82 are assembled with bolts to facilitate separation and assembly with the upper and lower stands 35 and 72. The return side rollers 82 also have the same configuration symmetrical to each other, which are assembled together with the side carrier rollers 37.

According to the present invention as described above, since the first carrier roller upper stand 35 and the return roller lower stand 72 are assembled integrally by the hinge shaft 52 and the hinge bar 54, a separate stand is unnecessary and a carrier is not required. When the belts 32 and 70 are opposite to each other when they return to each other, the acceleration force is reduced to each other, thereby reducing the force generated in the guide rail 15 and the side posts 10 on which the roller stand 35 is mounted. At the same time, since the return roller stand 72 is freely connected to the carrier roller stand 35, the return roller stand 72 is free to move from side to side due to the centrifugal force generated on the carrier side and the return side, respectively.

Secondly, the assembled unitary upper stand 35 is a wheel 40 of a bearing structure attached to the side of the stand frame, and the belt 32 and the package 100 along the side guide rails 15. As the centrifugal force generated by the swing motion. At this time, the upper and lower width of the guide groove (20a) of the rail (15) rather than the diameter of the wheel 40, the stand 35 is able to move, so that even a slight change in the rotation radius and the belt (32) on the stand (35) When the acceleration force in the advancing direction occurs, the flange portion 41 of the wheel 40 is supported by the guide groove 20a side of the rail 15.

Third, the height of the side rollers 37 and 82 is adjusted by the fastening bolt 37f and the nut 37e, thereby preventing the spillage of the package 100 due to the flattening of the belt 32 when the package is transported, and the belt 32 ) Improves the adhesion between the rollers (37) (39), by adjusting the friction force of the belt 32, the magnitude of the centrifugal force on the rollers (37) (39) is adjusted by the meandering control principle of the belt (32), The rollers 37 and 39 are easily assembled and dismantled, so that the parts can be easily replaced with a conveyor device.

Therefore, according to the conveyor apparatus of the present invention, it is possible to convey the package in the curved portion, so that when the package position is not a straight line, there is no need to install a separate connecting conveyor, unlike the conventional linear conveyor. In comparison, the height of the rollers 37 and 82 is adjusted from the side, so that the centrifugal force is reduced due to the belt tension adjustment by the friction between the belt 32 and the rollers 37 and 82, and thus, the swing width is also reduced, thus the package 100 ) The spillage is prevented, and the carrier and the return stand 35 and 72 are integrally formed, but the structure of the hinge shaft 52 and the hinge bar 54 can move freely to each other, thereby the stand structure as a whole. In this case, the assembly and the disassembly of the rollers 37, 39 and 82 are simplified, and the conveyance of the package at the curved portion is easily achieved.
