Fig. 1 is a top view of a mobile carrier 100 and a docking apparatus 102 in a docked state, and fig. 2 is a partially enlarged view at a in fig. 1. Referring to fig. 1 and 2, a docking mechanism according to an aspect of the present invention is used for docking a non-powered transmission 101 disposed on a mobile carrier 100 and a power device 103 disposed on a docking apparatus 102 docked with the mobile carrier 100. This mechanism of plugging into includes: a first engaging portion 104 and a second engaging portion 105. The first engaging portion 104 is provided on the mobile carrier 100, and has a first engaging member 106, and the first engaging member 106 is connected to and rotates synchronously with a first rotating shaft 107 at the front end of the unpowered transmission device 101. The second engaging portion 105 is provided on the docking apparatus 102, and includes a second rotating shaft 108, a second engaging member 109, a first cylinder 110, and a pushing member 111. The second rotating shaft 108 is connected with the power device 103 and is driven by the power device 103 to rotate. The second engaging member 109 is attached to the second rotating shaft 108 and rotates in synchronization with the second rotating shaft 108, and the second engaging member 109 is slidable in the axial direction (left-right direction in the drawing) of the second rotating shaft 108. The urging member 111 is driven by the first cylinder 110 in the axial direction of the second rotating shaft 108. The second engaging member 109 is connected to the pushing member 111 and is rotatable relative to the pushing member 111. In a state where the mobile carrier 100 and the docking apparatus 102 are docked, the second engaging member 109 is pushed by the pushing member 111 to engage with the first engaging member 106.

In the embodiment, since the first engaging member 106 and the second engaging member 109 are provided to engage in the axial direction, and the second engaging member 109 and the first engaging member 106 are engaged with each other adaptively while the second engaging member 109 is driven to rotate by the power device 103, the difficulty of connection can be reduced, and the reliability of connection between the unpowered transmission device 101 of the mobile carrier 100 and the power device 103 of the docking apparatus 102 can be improved.

The mobile carrier 100 may be, for example, an article vehicle or the like that carries materials, trays, and the like. The mobile carrier 100 is provided with a power transmission device 101, and the power transmission device 101 is a transmission device capable of continuous transmission, such as a belt transmission line, a timing belt 118 transmission line, or a chain transmission line. In addition, the unpowered transmission 101 is described herein, which means that the transmission is not directly provided with an independent power device on the mobile vehicle 100.

The transport device (not shown) may be, for example, an AGV car or another transport robot.

The docking facility 102 may be, for example, a feed stream line, or other processing facility, etc. A power unit 103 for driving the unpowered transmission 101 is provided on the docking apparatus 102. Thus, the mobile carrier 100 is directly driven by the power unit 103 of the docking facility 102 without providing an independent power to the mobile carrier 100. In the case where there are many mobile carriers 100, the cost of the mobile carriers 100 can be greatly reduced. Further, since the mobile vehicle 100 does not have independent power, it is not necessary to dispose electric power, an air source, and the like, and the path, the range, and the like, along which the mobile vehicle 100 can be carried can be greatly enlarged.

The power unit 103 may use a known rotation driving element such as a motor. The power means 103 may be a device dedicated to driving the unpowered actuator 101 or may be a power means provided on the docking apparatus 102 and using another powered belt that interfaces with the unpowered actuator 101.

Fig. 3 is a perspective view of the mobile carrier 100, fig. 4 is a perspective view of a rear end portion of the docking apparatus 102, fig. 5 is a partial enlarged view at B in fig. 3, and fig. 6 is a partial enlarged view at C in fig. 4. Referring to fig. 3 to 6, the first engaging piece 106 and the second engaging piece 109 can be engaged only, and the structure thereof is not particularly limited. For example, the first engaging member 106 has a disk shape, and a plurality of, for example, two axially protruding catches 112 are provided at intervals in the circumferential direction of the first engaging member 106 (see fig. 5). Correspondingly, the second engaging member 109 is also disc-shaped, and a plurality of, for example, four engaging grooves 113 (see fig. 6) are provided at intervals in the circumferential direction of the second engaging member 109. In a state where the first engaging member 106 and the second engaging member 109 are engaged, the latch teeth 112 of the first engaging member 106 are inserted into the latch grooves 113 of the second engaging member 109.

In the present embodiment, the carrying device carries the mobile carrier 100 to the rear end of the docking apparatus 102, and the docking is completed by a docking mechanism (not shown). The docking mechanism is not particularly limited as long as it can reliably dock the mobile carrier 100 and the docking device 102. For example, the docking mechanism positions the mobile carrier 100 and the docking apparatus 102 by driving a positioning pin with a cylinder. Furthermore, the docking mechanism may also drive the tensioning block by the air cylinder to tension the mobile carrier 100 towards the docking apparatus 102 to complete docking, etc.

After docking of the mobile carrier 100 and the docking apparatus 102 is completed, the docking of the unpowered transmission 101 and the power device 103 is completed by the docking mechanism of the present embodiment.

With continued reference to fig. 4 and 6, in some embodiments, the power device 103 is coupled to the second rotatable shaft 108 via a synchronous belt drive 114. Specifically, the rear end of the docking device 102 is provided with a chassis 115. The power unit 103, the timing belt drive mechanism 114, and the second engaging portion 105 are mounted on a frame 115. The position of the power unit 103 is not limited as long as it can be connected to the second rotating shaft 108 by the synchronous belt drive mechanism 114. The synchronous belt drive mechanism 114 includes, for example, a first synchronous pulley 116, a second synchronous pulley 117, and a synchronous belt 118 connecting the first synchronous pulley 116 and the second synchronous pulley 117. The first synchronous pulley 116 is coaxially connected to an output shaft of a motor (or a speed reducer) of the power unit 103. The second rotating shaft 108 is mounted to the frame 115 through, for example, a bearing block 119. The second timing pulley 117 is fitted in the second rotating shaft 108 by, for example, a key (not shown). Thereby, the second rotating shaft 108 can be rotationally driven by the power unit 103. Since the power unit 103 is connected to the second rotating shaft 108 via the timing belt drive mechanism 114, the power unit 103 can be attached to a place (for example, a lower place) away from the place where the first engaging portion 104 and the second engaging portion 105 are engaged with each other, and the difficulty of attaching the second engaging portion 105 can be reduced, and the attachment of the second engaging portion 105 can be made compact.

With continuing reference to fig. 4 and 6 and with additional reference to fig. 3, in some embodiments, at least one side of the docking device 102 in the left-right direction is provided with a plurality of second engaging portions 105 in the up-down direction. Specifically, for example, when the mobile carrier 100 has the unpowered transmission 101 in multiple stages, the docking apparatus 102 may be provided with a plurality of second engaging portions 105 along the vertical direction in order to match with the unpowered transmission 101 of the mobile carrier 100. In addition, when the plurality of unpowered apparatuses 101 are provided on both the left and right sides of the mobile carrier 100, the second engaging portions 105 may be provided on both the left and right sides of the docking facility 102.

In some embodiments, to reduce the number of the power devices 103, the second engaging portions 105 located on the same side of the docking apparatus 102 are respectively connected to the power devices 103 through the same synchronous belt transmission mechanism 114. Specifically, the description will be given taking an example in which two second engaging portions 105 are provided in the vertical direction. For example, the synchronous belt transmission mechanism 114 further includes a third synchronous pulley 120 and a plurality of transfer rollers 121, and the synchronous belt 118 connects the first synchronous pulley 116, the second synchronous pulley 117, and the third synchronous pulley 120 in series through the transfer rollers 121. Thereby, the power device 103 can simultaneously drive the second rotating shafts 108 to rotate.

In some embodiments, in order to optimize the structure of the docking mechanism and make the docking mechanism more compact, the left and right sides of the rack 115 disposed at the rear end of the docking device 102 are respectively provided with the upright columns 122, the upright columns 122 are provided with the receiving grooves 123, and the second engaging portions 105 are at least partially received in the receiving grooves 123. Specifically, for example, a channel steel material may be selected for the upright 122, and a U-shaped channel of the channel steel may be used as the receiving groove 123. Second engaging portion 105 is mounted to upright 122 by mounting plate 124. Two bearing blocks 119 supporting the second rotary shaft 108, one of which is mounted to the upright 122 and the other of which is mounted to the mounting plate 124. A first end 125 of one axial end of the second rotating shaft 108 is received in the receiving groove 123, and a second end 126 of the other axial end of the second rotating shaft 108 extends out of the receiving groove 123 of the upright post 122.

With continued reference to fig. 6 and with additional reference to fig. 2, the synchronous belt drive mechanism 114 is also at least partially accommodated in the accommodating groove 123. Specifically, the second timing pulley 117 (and the third timing pulley 120) is mounted on the first end 125 of the second rotating shaft 108 and is accommodated in the accommodating groove 123. The timing belt 118 partially extends in the receiving groove 123 and is connected to the power unit 103 installed at the lower portion of the column 122 by a transfer roller 121 installed at the outer side of the column 122. Therefore, the installation space of the accommodating groove 123 of the column 122 can be fully utilized, and the connection mechanism is more compact.

With continued reference to fig. 6, in some embodiments, to reliably urge the second catch member 109 into or out of engagement with the first catch member 106, the axial middle portion of the second catch member 109 is provided with an annular groove 127, and one end of the pusher 111 is fitted with a follower 128, the follower 128 extending at least partially into the annular groove 127. Specifically, the second engaging member 109 is erected at the second end portion 126 of the second rotating shaft 108 and is rotatable in its axial direction relative to the second rotating shaft 108 while rotating synchronously with the second rotating shaft 108. The follower 128 may be, for example, a known commercially available cam follower, and the first cylinder 110 slides the second engaging member 109 with respect to the second rotating shaft 108 by driving the pushing member 111 and moving the follower 128 axially along the second rotating shaft 108. In the present embodiment, since the follower 128 is used to contact the second engaging member 109, the frictional force of the second engaging member 109 in rotation can be greatly reduced, and the abrasion of the annular groove 127 of the second engaging member 109 can be effectively suppressed.

In some embodiments, in order to improve the smoothness of the sliding of the second engaging member 109 with respect to the second rotating shaft 108, one end of the pushing member 111 is provided with two arm portions 129 extending in a Y shape with respect to each other, and each arm portion 129 is provided with one follower 128. Specifically, the two arm portions 129 of the second engaging member 109 are located on both sides in the radial direction of the second engaging member 109, respectively, and the two followers 128 are also located on both sides in the radial direction of the second engaging member 109, respectively. Thereby, the two followers 128 can project into the annular groove 127 substantially symmetrically with respect to the second engaging member 109. Thus, the first cylinder 110 can slide the second engaging piece 109 with respect to the second rotating shaft 108 by the two followers 128 that are substantially symmetrical with respect to the second engaging piece 109, thereby improving the smoothness of the sliding movement of the second engaging piece 109.

In addition, although the first cylinder 110 pushes the second engaging member 109 by the follower 128 has been described as an example, the present invention is not limited thereto. For example, in some embodiments, the pushing member 111 may partially extend into the annular groove 127 to directly push the second engaging member 109. Specifically, for example, two arm portions 129 extending in a Y shape with respect to each other provided at one end of the pusher 111 may be caused to directly project into the annular groove 127.

According to the docking mechanism of the present embodiment, after the mobile carrier 100 and the docking apparatus 102 complete docking, the first engaging member 106 and the second engaging member 109 are in substantially coaxial positions. The power device 103 drives the second rotating shaft 108 and the second engaging member 109 to rotate slowly, and at the same time, the first air cylinder 110 pushes the second engaging member 109 to slide slowly along the axial direction of the second rotating shaft 108, the second engaging member 109 abuts against the first engaging member 106, and when the engaging groove 113 of the second engaging member 109 and the engaging tooth 112 of the first engaging member 106 are aligned gradually along with the slow rotation of the second engaging member 109, the second engaging member 109 slides slowly further along the axial direction of the second rotating shaft 108 due to the driving force of the first air cylinder 110. Thereby, the latch 112 of the first engaging member 106 is inserted into the latch slot 113 of the second engaging member 109, thereby completing the engagement of the first engaging member 106 and the second engaging member 109. When the second engaging piece 109 needs to be disengaged from the first engaging piece 106, the first cylinder 110 needs to be driven in the reverse direction.

Since the second engaging member 109 and the first engaging member 106 are engaged with each other adaptively while the second engaging member 109 is driven to rotate by the power device 103, the difficulty of connection can be reduced, and the reliability of connection between the unpowered transmission device 101 of the mobile carrier 100 and the power device 103 of the docking apparatus 102 can be improved.
