However, when explaining in detail the operating principle of a preferred embodiment of the present invention, if a detailed description of a related known function or configuration is judged to unnecessarily obscure the gist of the present invention, the detailed description will be omitted.

<Configuration>

As shown in FIG. 1, the diverter (D) equipped with the lifting device according to the present invention can be installed below the area where the roller conveyor devices (R) installed to transport goods in a straight direction intersect. This diverter (D) is configured so that the transport wheel 110 is located between the conveyor rollers (C) to rise or fall, and can be installed to transfer the transported object (A) by switching it in a direction other than a straight line when necessary. there is. At this time, the transfer wheel 110 may be arranged between the conveyor rollers (C), or may be arranged with one or two spaces between the rollers (C) in a certain pattern. Additionally, the conveyor roller (C) can be installed by connecting the conveyor frames (RF) arranged on both sides.

<First embodiment>

As a first embodiment of the present invention, a diverter having a structure in which reciprocating movement with a drive motor is converted into lifting movement includes a transfer means 100 and a lift means 200, as shown in FIG. 2.

First, the transfer means 100 here, as shown in Figures 2 to 5, the transfer means 100 includes a transfer wheel 110, a fixing bracket 120, a connection ring 130, a drive ring 140, and a drive. It may be provided with a wheel 150, a rotation shaft 160, and a drive shaft 170.

Here, as shown in Figures 3 and 4, a number of transport wheels 110 are arranged in a row on the vertical surface of the approximately 'ㄴ' shaped fixing bracket 120, and a connecting ring ( 130) or the driving ring 140 may be wound and connected. At this time, the connecting ring 130 and the driving ring 140 are wound and installed in a zigzag shape, and a detailed description thereof will be described later. Additionally, the transfer wheel 110 may have mounting grooves 111 machined in two rows on its outer edge as shown in FIG. 4 .

As shown in FIG. 4, this transfer wheel 110 minimizes the gap between adjacent transfer wheels 110 as much as possible, thereby preventing the edges of the transported object or the protruding ribs on the bottom from getting caught in the gap. At this time, if the gap between the transport wheels 110 is narrowed, the gap for inserting the connecting ring 130 or the driving ring 140 may not be guaranteed. Considering this, a portion of the outer edge of the transfer wheel 110 may be processed to be straight and flat. To explain in more detail, the transfer wheel 110 is formed by processing two rows of mounting grooves 111 as shown in FIG. The height of a portion of the wheel frame top 112 may be processed to be lower than the remaining wheel frame top 112. That is, just as the portions where the transport wheels 110 face each other in the enlarged upper view of FIG. 4 are machined flat, only some portions of the two wheel frame tops 112 can be machined flat. Therefore, when the two neighboring transport wheels 110 rotate to face the two low-height wheel frame tops 112, a gap can be provided through which the connecting ring 130 or driving ring 140 can pass. there is. Through this, the connecting ring 130 or the driving ring 140 can be mounted on the transfer wheel 110.

In addition, the transfer wheel 110 has a wheel bearing 113 mounted at the center and can be rotatably fastened in a line to the vertical surface of the fixing bracket 120. Looking at this fastening structure, the washer 116 is inserted into the fixing nut 114 fixed in line to the fixing bracket 120, and the fixing bolt 115 penetrating the wheel bearing 113 is attached to the fixing nut 114. can be concluded. At this time, the fixing nut 114 and washer 116 tightly tighten both sides of the wheel bearing 113 with the fixing bracket 120 in the center, thereby preventing the transfer wheel 110 from shaking or shaking. Accordingly, the transfer wheel 110 can avoid interference with the conveyor rollers (C) even if it is placed in a narrow gap between the conveyor rollers (C) and is lifted as shown in FIG. 3.

In addition, as shown in FIG. 5, some of the plurality of transfer wheels 110 are installed to rotate together with the drive wheel 150 via the drive ring 140, and the remaining transfer wheels 110 are installed to rotate together with the drive wheel 150. Adjacent transfer wheels 110 may be installed in pairs to rotate together via the connecting ring 130. At this time, the connecting ring 130 or the driving ring 140 may be arranged in a zigzag shape. That is, one transport wheel 110 may have a connecting ring 130 and/or a driving ring 140 wrapped around two mounting grooves 111, respectively.

As an example, the connection structure of the transfer wheel 110, the connecting ring 130, and the driving ring 140 will be described with reference to FIG. 5. First, the connection structure between most of the transfer wheels 110 and the connecting ring 130 is that the first transfer wheel 110a and the second transfer wheel 110b have the first row of mounting grooves 111. It is connected by a connecting ring 130 wound around, and the second transfer wheel 110b and the third transfer wheel 110c may be connected by another connecting ring 130 wound around the mounting groove 111 in the second row. In addition, the third transfer wheel (110c) and the fourth transfer wheel (110d) have a driving ring 140 wound around the first row of mounting grooves 111, and the fourth transfer wheel (110d) and the fifth transfer wheel (110e) Can be connected by wrapping the connecting ring 130 around the mounting groove 111 in the second row. In addition, the remaining transfer wheels 130, excluding the third transfer wheel 110c and the fourth transfer wheel 110d, may be connected to each other by wrapping the neighboring transfer wheels 130 with the connecting ring 130. In this way, the connecting ring 130 or the driving ring 140 is mounted on the transport wheel 110 in a zigzag shape, so that when the two transport wheels 110 equipped with the driving ring 140 rotate, the remaining transport wheels 110 They can rotate together by the connecting ring 130.

Additionally, the fixing bracket 120 may have an approximately “L” shape as shown in FIG. 4 . On the vertical surface of this fixing bracket 120, fixing nuts 114 on which the transport wheel 110 is mounted are installed at regular intervals, and on the horizontal surface, the upper transport wheel 110 and the lower driving wheel 150 are installed as shown in FIG. 4. A driving ring hole 121 may be provided through which the connecting driving ring 140 passes. In addition, a number of holes may be machined on the horizontal surface of the fixing bracket 120 for fixing it to the upper surface of the lifting plate 230. Here, the fixing nut 114 may be a blind nut. In addition, the fixing bracket 120 may be fixed to the lifting plate 230 by welding. In addition, in order to improve the load bearing capacity including the transport wheel 110, the fixing bracket 120 may be manufactured in a shape in which the vertical surface has an inclined portion at an acute or obtuse angle from the horizontal plane and a vertical portion that is vertical again at the end of the inclined portion. there is.

In addition, as mentioned above, the connecting ring 130 is wound and installed in the mounting groove 111 of the two adjacent transport wheels 110 in a zigzag shape, and the rotation of one transport wheel 110 is controlled by the other transport wheel 110. It can have enough tension to transmit to . For this purpose, the connecting ring 130 may be made of rubber or silicone material with high friction, or may be made of a belt or gear. In addition, since the connecting ring 130 fills the gap between neighboring transport wheels 110, it is possible to minimize the phenomenon of corners of the transported object or protruding ribs on the bottom being caught in the gap.

Additionally, the driving ring 140 may be installed wrapped around some of the transport wheels 110 and the drive wheel 150 among the transport wheels 110, as mentioned above. At this time, the driving ring 140 may be disposed through the driving ring hole 121 of the fixing bracket 120. Additionally, the driving ring 140 may be made of rubber or silicone material with high friction so that the rotation of the driving wheel 150 is partially transmitted to the transfer wheel 110, and may also be made of a belt or gear.

Additionally, the driving wheel 150 may be mounted on the rotating shaft 160 fixed to the lower surface of the lifting plate 230. As shown in FIG. 3, a plurality of drive wheels 150 can be installed on the rotation shaft 160 in accordance with the multiple rows of transfer wheels 110.

Additionally, the rotation shaft 160 may be firmly fixed to the lower surface of the lifting plate 230 and rotated by the driving shaft 170.

Additionally, the drive shaft 170 may be arranged side by side next to the rotation shaft 160 and interconnected with a plurality of chains or belts arranged in the longitudinal direction. Accordingly, the power of the drive shaft 170 may be transmitted by a chain or belt to rotate the rotation shaft 160.

Meanwhile, as shown in FIG. 2, the lifting means 200 may include a base plate 210, a sliding plate 220, a lifting plate 230, and a driving unit 240.

As shown in Figure 2, the base plate 210 is fixed by connecting the lower part of the roller frame (RF) installed on both sides of the conveyor roller (C), and a sliding plate 220 and a lifting plate 230 are arranged on the upper side. It is absence. This base plate 210 has a left and right length fixed by connecting the roller frames (RF) on both sides in a plane as shown in FIGS. 6A and 6B, and is long enough to accommodate the transport wheels 110 arranged in multiple rows as shown in FIG. 1. It may be of a size having a front-to-back length of . For example, the base plate 210 may have a substantially square shape.

As shown in FIGS. 6A and 6B, this base plate 210 has fasteners 211 processed for bolting with the lower part of the roller frame (RF) on the left and right edges in a plan view, and a drive motor 241 processed to be fixed near the center. It may be provided with a plurality of fixing holes 212, a through hole 213 machined in the center, and a cut portion 214 machined from the center to the four corners.

At this time, the distal end of the cut portion 214 is fastened to the support portion 232 of the lifting plate 230 as shown in Figure 11 or 12, and is cut together with the support portion 232 while the lifting plate 230 is lifted. The part 210 may rise and fall elastically. Due to this, by fastening the support portion 232 and the cutout portion 210, the sliding plate 230 can be freely raised and lowered, but positional deviation in directions other than the raised and lowered portion, i.e., forward, backward, left, and right, can be prevented. In addition, the roughly 'v' shape of the incision 214 is intended to lengthen the incision line and distribute the pressure applied to the incision 214 as much as possible so as not to break it due to repeated elastic lifting and lowering. In other words, as the length of the incision section 214 becomes shorter, the possibility of fracture due to repetitive elastic lifting may increase.

As shown in FIG. 2, the sliding plate 220 is a member that reciprocates on the upper surface of the base plate 210. As shown in FIGS. 7A and 7B, the sliding plate 220 is large enough to move approximately a certain distance on the base plate 210 in plan, and may have a substantially square shape, for example. In addition, the sliding plate 220 has a guide flange 221 in which the left and right parts on the front are bent upward and machined, and a lifting guide hole 222 machined in an upper and lower diagonal line on the front and rear of the guide flange 221 on the left side. ), a sliding roller 223 mounted near the lifting guide hole 222 of the guide flange 221 on the left side, a fixed cover 224 processed to be convex upward in the center of the front view, and below the fixed cover 224 It may be provided with a sliding guide hole (225) machined long in the front-back direction.

Here, as shown in FIGS. 11 and 12, the lifting guide hole 222 is, for example, machined diagonally upward to the right, and the lifting roller 233 of the lifting plate 230 can be mounted. The upper diameter (r1) of this lifting guide hole (222) is processed to be wider than the diameter (r2) of the remaining part, and after being inserted through this wider diameter (r1), the concave rolling surface of the lifting roller (233) is formed in the remaining part. (F) can be installed so that it hangs over. Accordingly, while the sliding plate 220 reciprocates, the lifting roller 233 rises or falls along the lifting guide hole 222, thereby allowing the lifting plate 230 to go up and down.

Additionally, the sliding roller 223 is placed on the upper surface of the base plate 210 and can perform a rolling motion while the sliding plate 220 moves back and forth.

In addition, the fixed cover 224 may be provided with sliding roller mounting holes 224a that are long and machined left and right on the front upper surface. The eccentric body 243 of the drive motor 241 is located in this fixed cover 224, and the eccentric rotating roller 244 of the drive motor 241 located below the front is inserted into the sliding roller mounting hole 224a. You can. Here, as shown in FIGS. 7A and 7B, the sliding roller mounting hole 224a may be processed so that the diameter (r1) of one part is wider than the diameter (r2) of the remaining part. Therefore, the eccentric rotating roller 244 can be installed in the sliding roller mounting hole 224a by inserting the eccentric rotating roller 244 through the wide diameter r1 and then moving it to the remaining area. In addition, the eccentric rotating roller 244 may be assembled and mounted across the sliding roller mounting hole 224a. In addition, the eccentric rotating roller 244 can be processed to have a concave rolling surface like the lifting roller 233.

Additionally, the sliding guide hole 225 may be machined in a direction approximately perpendicular to the sliding roller mounting hole 224a, that is, in the forward/backward movement direction of the sliding plate 220. Therefore, while the eccentric rotation roller 244 rotates eccentrically, positional deviation can be prevented by the sliding guide hole 225.

Therefore, as shown in FIG. 10, the eccentric body 243 and the eccentric rotating roller 244 rotate eccentrically and push or pull the fixed cover 224 on which the sliding roller mounting hole 224a is machined back and forth, so that the sliding plate 220 reciprocates back and forth. do.

As shown in FIG. 2, the lifting plate 230 is mounted on the base plate 220 and is a member that moves up and down while the sliding plate 220 moves back and forth. This lifting plate 230 may be equipped with a transfer wheel 110 and a fixing bracket 120 on its upper surface, as shown in FIGS. 2 and 8A and 8B. This lifting plate 230 is located on the left and right sides from the front, and includes a mounting portion 231 that is processed by bending the front and rear portions downward, and a support portion 232 that is processed by bending horizontally from the bottom of the mounting portion 231. , It may be provided with a lifting roller 233 mounted on the mounting portion 231 and a pair of shaft coupling portions 234 that are bent downward near the center of the front view and machined on the front and back sides.

Here, a lifting roller 233 may be mounted on the mounting portion 231.

Additionally, the lifting roller 233 may have a concave rolling surface (F). As a result, the concave part of the rolling surface (F) hangs over the edge of the lifting guide hole 222 of the sliding plate 220, preventing the lifting roller 233 from being separated while mounted in the lifting guiding hole 222. And, the concave portion may contact a portion of the edge of the lifting guide hole 222 to rotate the lifting roller 233. And when the sliding plate 220 moves back and forth, the lifting roller 233 moves up and down along the lifting guide hole 222, and the lifting plate 230 may also move up and down.

In addition, the shaft coupling portion 234 may be machined with a drive shaft fastening hole 234a into which both ends of the drive shaft 170 are mounted, and a rotation shaft fastening hole 234b into which both ends of the rotation shaft 160 are mounted, as shown in FIG. 8A. Here, when the rotation shaft 160 is driven by a separate motor instead of the drive shaft 170, the drive shaft fastening hole 234a can be excluded.

And, as shown in FIGS. 11 and 12, the support portion 232 may be fastened to the tip of the cutout portion 214 of the base plate 210. Accordingly, while the lifting plate 230 can be raised and lowered, deviation of the lifting plate 230 from the base plate 210 in forward, backward, left and right directions other than the lifting and lowering can be prevented.

As shown in FIG. 9, the drive unit 240 includes a drive motor 241, a central rotation shaft 242 rotated by the drive motor 241, an eccentric body 243 mounted on the central rotation shaft 242, and this eccentric body. It may be provided with an eccentric rotation roller 244 that is mounted on (243) and rotates eccentrically about the central rotation axis 242.

At this time, the rolling surface (F) of the eccentric rotating roller 244 may be processed to be approximately concave. Accordingly, the mounted state can be maintained by covering the sliding roller mounting hole 224a over the concave portion of the rolling surface F. In addition, when the eccentric rotating roller 244 is mounted on the sliding roller mounting hole 224a, the concave portion of the eccentric rotating roller 244 is in contact with a portion of the edge of the sliding roller mounting hole 224a, thereby causing the eccentric rotating roller 244 ) may be rotated. In addition, the sliding roller mounting hole 224a, like the lifting guide hole 222, is machined so that the diameter of some parts is wider than the diameter of the remaining parts, and the eccentric rotating roller 244 is inserted through the wide diameter to create a rolling surface ( The concave part of F) can be stretched.

Here, as shown in FIGS. 2, 6A to 7B, and FIG. 9, the drive motor 241 is fixed to the base plate 210 through the fixing hole 212, and the central rotation axis 242 is connected to the through hole 213. ), the eccentric body 243 is accommodated in the fixed cover 224 of the sliding plate 220, and the eccentric rotating roller 244 is installed in the sliding roller mounting hole 224a of the fixed cover 224. You can.

<Second Embodiment>

Hereinafter, a diverter having a structure in which reciprocating movement is converted into lifting movement according to the second embodiment of the present invention will be described. Since the transfer means 100 in the first embodiment is applied in the same way, it will be briefly described when necessary, and the lifting means 200 will be described in detail.

As shown in FIG. 13, the lifting means 200 may include a base plate 210, a sliding plate 220, a lifting plate 230, and a driving unit 240.

As shown in FIG. 13, the base plate 210 is fixed by connecting the lower ends of the roller frames (RF) installed on both sides of the conveyor roller (C), and a sliding plate 220 and a lifting plate 230 are arranged on the upper side. It is absence. This base plate 210 has a left and right length fixed by connecting the roller frames (RF) on both sides in a plane as shown in FIGS. 14a and 14b, and is long enough to accommodate the transport wheels 110 arranged in multiple rows as shown in FIG. 1. It may be of a size having a front-to-back length of . For example, the base plate 210 may have a substantially square shape.

As shown in FIGS. 14a and 14b, this base plate 210 has fasteners 211 processed for bolting to the roller frame (RF) on the left and right edges in plan, and protrudes upward to secure the rear of the cylinder 245 in the center. It may be provided with a fixing piece 215 and cut portions 214 machined from the center to the four corners.

At this time, the distal end of the cut portion 214 is fastened to the support portion 232 of the lifting plate 230 as shown in FIGS. 17 and 18, and is cut together with the support portion 232 while the lifting plate 230 is lifted. The part 210 may rise and fall elastically. Due to this, by fastening the support portion 232 and the cutout portion 210, the sliding plate 230 can be freely raised and lowered, but positional deviation in directions other than the raised and lowered portion, i.e., forward, backward, left, and right, can be prevented. In addition, the roughly 'v' shape of the cut part 214 is intended to lengthen the cut line and distribute the pressure applied to the cut part 214 as much as possible so as not to break it due to repeated elastic lifting and lowering. In other words, as the length of the incision section 214 becomes shorter, the possibility of fracture due to repetitive elastic lifting may increase.

As shown in FIG. 13, the sliding plate 220 is a member that reciprocates on the upper surface of the base plate 210. As shown in FIGS. 15A and 15B, the sliding plate 220 is large enough to move approximately a certain distance on the base plate 210 in plan, and may have a roughly square shape, for example. In addition, the sliding plate 220 has a guide flange 221 in which the left and right parts on the front are bent upward and machined, and a lifting guide hole 222 machined in an upper and lower diagonal line on the front and rear of the guide flange 221 on the left side. ), a sliding roller 223 mounted near the lifting guide hole 222 of the guide flange 221 on the left side, and a fastening in which the rod 246 of the cylinder 245 is mounted on the center portion of the plan view, protruding upward from the front. It may be provided with a piece 226 and a through hole 227 machined near the fastening piece 226.

Here, as shown in FIGS. 17 and 18, the lifting guide hole 222 is, for example, machined diagonally upward to the right, and the lifting roller 233 of the lifting plate 230 can be mounted. Accordingly, while the sliding plate 220 reciprocates, the lifting roller 233 diagonally rises or falls along the lifting guide hole 222, thereby allowing the lifting plate 230 to move up and down.

Additionally, the sliding roller 223 is in contact with the upper surface of the base plate 210 and can perform a rolling motion while the sliding plate 220 moves back and forth.

In addition, the through hole 227 is processed so that the cylinder 245 fixed to the base plate 210 passes through and the rod 246 of the cylinder 245 is fixed to the fastening piece 226, and the sliding plate 220 is The size may be such that there is no interference between the cylinder 245 and the sliding plate 220 during reciprocating movement.

And the rod 246 of the cylinder 245 located through the passage hole 227 can be fixed to the fastening piece 226, as shown in FIG. 17. Therefore, when the rod 246 reciprocates back and forth, the sliding plate 220 may reciprocate via the fastening piece 226.

As shown in FIG. 13, the lifting plate 230 is mounted on the base plate 210 and is a member that moves up and down while the sliding plate 220 moves back and forth. As shown in FIGS. 13 and 16A and 16B, the lifting plate 230 may be equipped with a transfer wheel 110 and a fixing bracket 120 on its upper surface. This lifting plate 230 is located on the left and right sides from the front, and includes a mounting portion 231 that is processed by bending the front and rear portions downward, and a support portion 232 that is processed by bending horizontally from the bottom of the mounting portion 231. , It may be provided with a lifting roller 233 mounted on the mounting portion 231 and a pair of shaft coupling portions 234 that are bent downward near the center of the front view and machined on the front and back sides.

Here, a lifting roller 233 may be mounted on the mounting portion 231.

Additionally, the lifting roller 233 may have a concave rolling surface (F). As a result, the concave portion of the rolling surface (F) hangs over the edge of the lifting guide hole 222 of the sliding plate 220, causing the lifting roller 233 to break away while mounted in the lifting guiding hole 222. This prevents the lifting roller 233 from rotating by contacting the concave portion with some edges of the lifting guide hole 222. And when the sliding plate 220 moves back and forth, the lifting roller 233 moves up and down along the lifting guide hole 222, and the lifting plate 230 may also move up and down.

In addition, the shaft coupling portion 234 may be machined with a drive shaft fastening hole 234a into which both ends of the drive shaft 170 are mounted, and a rotation shaft fastening hole 234b into which both ends of the rotation shaft 160 are mounted, as shown in FIG. 16A. At this time, the drive shaft 170 may be installed to rotate the rotation shaft 160.

And, as shown in FIGS. 17 and 18, the support portion 232 may be mounted on and fastened to the tip of the cut portion 214 of the base plate 210. Accordingly, while the lifting plate 230 can be raised and lowered, deviation of the lifting plate 230 from the base plate 210 in forward, backward, left and right directions other than the lifting and lowering can be prevented.

As shown in FIG. 17, the driving unit 240 may include a cylinder 245.

Here, as shown in FIGS. 13, 17, and 18, the rear of the cylinder 245 is fixed to the fixing piece 215 of the base plate 210, and the rod 246 of the cylinder 245 is attached to the sliding plate 220. ) can be mounted on the fastening piece 226.

<Operation>

Hereinafter, the operation of the lifting device using the cylinder 245 as a power source will be described with reference to FIGS. 17 and 18.

First, as shown in FIG. 17, the rod 246 of the cylinder 245 may not be pulled out at the initial position where the lifting plate 230 is lowered. At this time, the lifting roller 233 may be located at the lower part of the lifting guide hole 222.

Next, when the rod 246 of the cylinder 245 is pulled out, the sliding plate 220 can be moved forward, as shown in FIG. 18. At this time, the sliding plate 220 moves forward with respect to the base plate 210 by the sliding roller 223, and as the lifting roller 233 rises along the lifting guide hole 222, the lifting plate 230 moves forward. We can rise together.

Finally, as the rod 246 of the cylinder 245 retreats, the sliding plate 220 moves rearward and returns to its original position, and as the lifting roller 233 descends along the lifting guide hole 222, the lifting plate 230 also moves. It can be lowered and returned to its original position.
