In one embodiment, the first gear structure transmits the rotational power of the first drive shaft (made 141) of the first drive motor 140 to the first housing 121 to move the first housing 121 to the first shaft (A2). ) can be rotated around. In one embodiment, the first gear structure may be disposed inside the first housing 121. In one embodiment, the first gear structure may include, for example, a planetary gear structure. Hereinafter, the description will focus on an embodiment in which the first gear structure has a planetary gear structure. However, the first gear structure is not limited to this, and the first gear structure can be formed as a power transmission structure in various ways that can dynamically connect the first drive motor 140 and the first housing 121. You should keep in mind.

In one embodiment, the first gear structure includes a first drive gear 1411 and a first carrier mounted on the first drive shaft 141, a first ring gear 1211 connected to the first housing 121, and a carrier. It may include a plurality of first planetary gears (122a, 122b, 122c) connected to and engaged with the first drive gear (1411) and the first ring gear (1211).

In one embodiment, the first drive gear 1411 is mounted on the outer surface of the first drive shaft 141 and may rotate together with the rotation of the first drive shaft 141. The first carrier is connected to the first drive shaft 141 and can support first planetary gears 122a, 122b, and 122c, which will be described later, around the first drive shaft 141. In one embodiment, the first carrier may include a plurality of support portions spaced apart by a certain angle to support a plurality of planetary gears. For example, as shown in FIG. 5, when the first gear structure includes three first planetary gears 122a, 122b, and 122c, the first carrier is rotated 120 degrees around the first drive shaft 141. It may include three support parts arranged at intervals.

In one embodiment, the first ring gear 1211 may be connected to the inner peripheral surface of the first housing 121 to surround the first drive shaft 141. The first ring gear 1211 may be formed in a ring shape centered on the first drive shaft 141. In one embodiment, the first ring gear 1211 may be fixed to the inner peripheral surface of the first housing 121.

It can be arranged so that For example, the first planetary gears 122a, 122b, and 122c may be disposed between the first drive gear 1411 and the first ring gear 1211.

According to this structure, as the first drive shaft 141 of the first drive motor 140 rotates, the power of the first drive motor 140 is transferred to the first drive gear 1411, the first planetary gear 122a, It is transmitted to the first housing 121 through 122b, 122c) and the first ring gear 1211, and the first housing 121 can rotate. In one embodiment, when the first gear structure is formed as a planetary gear structure, the volume is small compared to other gear structures having the same transmission ratio, so when the first gear structure is installed in the first housing 121, the volume is relatively small. A high transmission ratio can be realized. In addition, since the first drive shaft 141, which is the input shaft of power, and the first output shaft of the first housing 121, which is the output shaft, are located concentrically, power transmission efficiency is high, making it possible to reduce the size and weight. Therefore, it is possible to secure high power transmission efficiency while reducing the overall size of the cable (W) transmission device 1.

In one embodiment, the second transmission unit 110 may have substantially the same structure as the first transmission unit 120. For example, the second delivery unit 110 may include a second housing 111, a second delivery member 117, and a second gear structure.

In one embodiment, the second housing 111 may rotate on the upper part of the moving member 161 about the second axis A1.

The second housing 111 may include a hollow formed inside so that at least a portion of the second drive motor 130 is inserted therein. That is, when looking at the first surface 100A of the support plate 100, the second drive motor 130 may be located inside the second housing 111. In one embodiment, the second axis A1 of the second housing 111 may coincide with the second drive shaft 131 of the second drive motor 130.

In one embodiment, the second delivery member 117 is connected to the outer peripheral surface of the second housing 111 and may rotate depending on the rotation of the second housing 111. The second delivery member 117 is in direct contact with the outer surface of the cable (W) and can move the cable (W) in one direction through frictional force due to rotation. In one embodiment, the second delivery member 117, like the first delivery member 127, may include a material with high friction, for example, a rubber material.

In one embodiment, the second gear structure may dynamically connect the second drive motor 130 and the second housing 111. In one embodiment, the second gear structure transmits the rotational power of the second drive shaft 131 of the second drive motor 130 to the second housing 111 to move the second housing 111 to the second axis A1. It can be rotated around . In this case, the rotation direction of the second housing 111 around the second axis A1 may be opposite to the rotation direction of the first housing 121 around the first axis A2.

In one embodiment, the second gear structure may have the same transmission ratio as the first gear structure. For example, the second gear structure may include the same gear structure as the first gear structure, for example, a planetary gear structure. As with the first gear structure, the following description will focus on an embodiment in which the second gear structure has a planetary gear structure. However, it should be noted that the second gear structure is not limited to this, and the second gear structure may be formed with a gear structure different from the first gear structure.

In one embodiment, the second gear structure may include a second drive gear 1311 mounted on the second drive shaft 131 and a second carrier. The second drive gear 1311 is mounted on the outer surface of the second drive shaft 131 and can rotate together with the second drive shaft 131, and the second carrier is connected to the second drive shaft 131 to create a second planetary system described later. It can support gears 112a, 112b, and 112c.

In one embodiment, the second ring gear 1111 may be connected to the inner peripheral surface of the second housing 111 to surround the second drive shaft 131. The second ring gear 1111 may be formed in a ring shape centered on the second drive shaft 131. In one embodiment, the second ring gear 1111 may be fixed to the inner peripheral surface of the second housing 111. In another example, the second ring gear 1111 may be formed integrally with the second housing 111 by forming gear teeth on the inner peripheral surface of the second housing 111. For example, the second housing 111 may rotate integrally with the rotation of the second ring gear 1111 centered on the second drive shaft 131.

In one embodiment, the plurality of second planetary gears (112a, 112b, 112c) are each rotatably connected to the support portion of the second carrier and engage with the second drive gear 1311 and the first ring gear 1211. It can be arranged so that For example, the second planetary gears 112a, 112b, and 112c may be disposed between the second drive gear 1311 and the second ring gear 1111.

According to this structure, as the second drive shaft 131 of the second drive motor 130 rotates, the power of the second drive motor 130 is transferred to the second drive gear 1311, the second planetary gear 112a, It is transmitted to the second housing 111 through 112b, 112c) and the second ring gear 1111, and the second housing 111 can rotate. When the second gear structure is formed as a planetary gear structure, like the first gear structure, it can be installed in the second housing 111 and achieve a relatively high transmission ratio compared to other gear structures. In addition, since the second drive shaft 131 and the second axis A1 are located concentrically, power transmission efficiency is high, making it possible to make the structure smaller and lighter. In particular, the first drive motor 140 and the second drive motor 130 are disposed inside the first housing 121 and the second housing 111, respectively, and the gear structure for power transmission is also located in the first housing 121. And since it is disposed inside the second housing 111, the structure for power transmission is miniaturized, and the overall size of the cable (W) transmission device 1 can be reduced.

In addition, as in the embodiment, when the first gear structure and the second gear structure have the same transmission ratio, if only the rotational torque of the first drive motor 140 and the second drive motor 130 is controlled to be the same, the first transmission The unit 120 and the second transmitter 110 may rotate in a synchronized state. For example, since the first transmission unit 120 and the second transmission unit 110 have the same rotational torque and can rotate in opposite directions, a stable transmission operation of the cable W can be performed only with simple motor control. .

In one embodiment, the guide unit 160 may adjust the position of the moving member 161 with respect to the support plate 100. In one embodiment, the guide unit 160 may be disposed on the second surface 100B of the support plate 100. In one embodiment, the guide unit 160 may include a pair of support members 164, a position adjustment member 162, and a connection member 164.

In one embodiment, a pair of support members 1641 and 1642 may be disposed on the second surface 100B of the support plate 100, respectively, at both ends of the guide slot 101 in the longitudinal direction. In one embodiment, the position adjustment member 162 is connected to the pair of support members 1641 and 1642 with a bearing and can rotate while maintaining its position relative to the support plate 100.

In one embodiment, the position adjustment member 162 may adjust the position of the connection member 164 with respect to the guide slot 101. The position adjustment member 162 may overlap the guide slot 101 when looking at the second surface 100B of the support plate 100, as shown in FIG. 4A. The position adjustment member 162 may extend along the central axis parallel to the longitudinal direction of the guide slot 101. In one embodiment, the position adjustment member 162 is connected to a pair of support members 1641 and 1642 along a central axis by bearing, and can rotate about the central axis by manipulation. In one embodiment, threads may be formed on the outer peripheral surface of the position adjustment member 162.

In one embodiment, the connecting member 164 may be screwed to the positioning member 162. For example, a screw hole into which the position adjustment member 162 is inserted may be formed in the connecting member 164. The connecting member 164 is disposed on the guide slot 101 and can move on the guide slot 101 along the central axis direction of the position adjusting member 162 as the position adjusting member 162 rotates. In one embodiment, the connecting member 164 may be connected to the moving member 161. In one embodiment, the connecting member 164 may be fixedly connected to the moving member 161 as shown in FIG. 4A. In this case, according to the connection position of the connection member 164 with respect to the position adjustment member 162, for example, the position of the connection member 164 on the guide slot 101 changes, the moving member 161 connected to the connection member 164 ) moves. For example, when the position adjustment member 162 rotates in one direction (e.g., when rotating clockwise about the It is possible to move in the +X direction along and move the moving member 161 toward the fixing member. On the other hand, when the position adjustment member 162 rotates in the opposite direction (e.g., when rotating counterclockwise around the It is possible to move in the -X direction along and move the moving member 161 away from the fixing member. For example, according to the rotational movement of the position adjustment member 162, the moving member 161 moves along the longitudinal direction on the guide slot 101, so the second delivery unit 110 mounted on the moving member 161 is fixed. It may move away from or get closer to the first sending unit 120 mounted on the member. Therefore, depending on the diameter of the cable (W) used in the cable (W) transmission device 1, the gap between the first transmission unit 120 and the second transmission unit 110 can be adjusted.

In one embodiment, an auxiliary motor 170 for rotating the position adjustment member 162 may be connected to the position adjustment member 162. However, the position adjustment member 162 may be manually operated by the user.

In one embodiment, the moving member 161 may be partially movably connected to the connecting member 164. For example, as shown in FIG. 4B, the moving member 161 may be partially movably connected to the connecting member 164 through the position adjusting unit 165 along a direction parallel to the longitudinal direction. For example, a connecting bar 1651 parallel to the longitudinal direction of the guide slot 101 is connected to the connecting member 164, and the moving member 161 may be slidably connected to the connecting bar 1651. In one embodiment, an elastic member 1652 may be disposed between the moving member 161 and the connecting member 164. The elastic member 1652 connects the moving member 161 and the connecting member 164, and partially adjusts the gap between the moving member 161 and the connecting member 164, while maintaining the restoring force due to compression/stretching. Elastic force can be applied to the moving member 161 through.

In one embodiment, the elastic member 1652 may apply an external force in a direction in which the moving member 161 moves away from the connecting member 164 (e.g., +X direction in FIG. 4B), that is, in a direction toward the fixing member. . On the other hand, when force is applied to the moving member 161 in the direction in which the elastic member 1652 is compressed, the elastic member 1652 is compressed and moves the moving member 161 in a direction toward the connecting member 164 (e.g., Figure 4b). of -X direction), that is, an external force can be applied in a direction away from the fixing member.

According to this structure, based on the process of the cable (W) transmission device 1 transmitting the cable (W), the cable (W) sandwiched between the second transmission unit 110 and the first transmission unit 120 Even if the cross-sectional size of changes, the cable W can be stably supported by partially adjusting the position of the second delivery unit 110 without adjusting the position of the moving member 161. For example, when the cross-section of the cable (W) supported by the first transmission unit 120 and the second transmission unit 110 increases (e.g., due to the connection area where the cable (W) is connected, (when the cross-section of the supported cable (W) increases), the moving member 161 compresses the elastic member 1652 and moves partially toward the connecting member 164, and the second transmitting unit 110 transmits the first transmitting member 164. The gap formed between the parts 120 can be widened. In this case, since elastic force is applied to the moving member 161 by the restoring force of the elastic member 1652, the gap between the second delivery unit 110 and the first delivery unit 120 is prevented from widening excessively, It can enable stable support of the cable (W). On the other hand, when the increased cross-section of the cable (W) decreases again, the moving member 161 moves partially away from the connecting member 164 by the restoring force of the elastic member 1652 as the external force decreases. The gap between the second transmission unit 110 and the first transmission unit 120 may be narrowed. For example, according to the above-described structure, it is possible to partially adjust the position of the moving member 161 with respect to the connecting member 164, so that the cross section of the cable (W) can be adjusted without the process of adjusting the position of the moving member 161. As the size changes, the gap between the transmitting parts is immediately finely adjusted, enabling stable support of the cable (W).

In one embodiment, the auxiliary motor 170 is disposed on the second surface 100B of the support plate 100 and is connected to the position adjusting member 162 to move the position adjusting member 162 in both directions about the central axis. It can be rotated.

In one embodiment, when looking at the second surface 100B of the support plate 100 as shown in FIG. 3, the guide unit 160 and the auxiliary motor 170 may be covered by the cover unit 1600. Since components for operating the first transmitter 120 and the second transmitter 110 (e.g., drive motor, gear structure, etc.) are not disposed on the second surface 100B of the support plate 100, the support The size and structure of the components disposed on the second surface 100B of the plate 100 can be simplified. The cover unit 1600 covers the guide unit 160 and the auxiliary motor 170, thereby protecting the operating structure of the guide unit 160.

In one embodiment, the cable (W) transmission device 1 may include a detection sensor unit (not shown) and a processor (not shown). In one embodiment, the detection sensor unit can detect the operating state of the cable (W) transmission device 1 in real time. For example, the detection sensor unit detects the rotational state of the first delivery unit 120 and the second delivery unit 110, for example, the rotational torque of the first delivery member 127 and the second delivery member 117 in real time. can do. In one embodiment, the detection sensor unit may measure the tension of the cable (W) transmitted by the cable (W) transmission device (1).

In one embodiment, the processor may control the operation of the cable (W) delivery device (1). The processor determines the first transmission unit 120 and the second transmission unit 110 based on the information detected by the detection sensor unit, for example, the change in rotational torque of the first transmission member 127 and the second transmission member 117. ) can be detected. In one embodiment, when the processor determines that the first transmitter 120 and the second transmitter 110 do not rotate in synchronization, for example, the tension of the cable W decreases or the second transmitter 110 decreases. If it is determined that there is a difference in the rotational speed or rotational torque of the first transmission unit 120 and the second transmission unit 110, the first transmission unit 120 and the second transmission unit 110 are operated in a synchronized state. The operation of the first drive motor 140 and the second drive motor 130 can be controlled.

In one embodiment, the processor applies PWM (PWM) to the first drive motor 140 and the second drive motor 130 so that the first transmitter 120 and the second transmitter 110 rotate at the same rotation speed. pulse width modulation) signals can be controlled in real time. In one embodiment, the first gear structure of the first transmission unit 120 and the second gear structure of the second transmission unit 110 have the same gear transmission ratio, and the first drive motor 140 and the second drive motor ( When 130) is provided as a motor with the same specifications, the processor can control the first drive motor 140 and the second drive motor 130 to rotate at the same speed.

In one embodiment, the processor may control the operating output of the drive motor according to set conditions. For example, the processor receives information about the withdrawal speed of the cable (W), and controls the operation output of each of the driving motors 130 and 140 based on the input information to operate the first transmitter 120 and the first transmitter 120. 2 The rotation speed of the delivery unit 110 can be changed.

In one embodiment, the processor may control the operation of the auxiliary motor 170 based on information detected by the detection sensor unit. For example, when the tension of the cable (W) decreases while the two drive motors are operating at the same output, the processor causes the first delivery member 127 and the second delivery member 117 to It can be determined that (W) is not pressurized. On the other hand, when it is detected that the rotational torque of the first delivery unit 120 and the second delivery unit 110 is reduced, the processor causes the first delivery member 127 and the second delivery member 117 to exert excessive force. It can be judged that the cable (W) is pressurized. In this case, the processor controls the operation of the auxiliary motor 170 to rotate the position adjustment member 162, thereby adjusting the gap between the first transmitter 120 and the second transmitter 110. For example, the processor operates the guide unit 160 through control of the auxiliary motor 170 so that the first delivery member 127 and the second delivery member 117 can support the cable W with a pressing force within a set range. The moving member 161 can be moved by operating it.
