In one or more embodiments of the present invention, the cover conveyor further includes a conveying device. The conveying device is at least partially positioned on one side of the receiving plate away from the stop portion.

The above-described embodiments of the present invention have at least the following advantages:

(1) Because the shortest width of the first opening (and the second opening) of the cover separating structure is smaller than the longest width of the cover, when the cover passes through the first opening and the second opening of the cover separating structure, the cover is blocked by edges forming the first opening and the second opening, so that the soft cover is deformed. In this way, when the cover is stuck together with another cover or covers due to static electricity, the cover or covers stuck together with the covers sucked by the first suction means and the second suction means will be separated from the sucked cover or covers by the deformation of the cover. Therefore, the cover body separating structure can maintain the quantity of cover bodies driven to rise by the first suction device and the second suction device at one piece, and effectively improves the operation efficiency of the cover body conveyor.

(2) Because the height distance between the cover separating structure and the level of the cover stacked at the highest one is smaller than the longest width of the cover, namely smaller than the diameter of the cover in a round shape, when one or more covers stuck together with the cover absorbed by the first absorbing device and the second absorbing device are separated from the absorbed cover, one or more covers falling to the first accommodating space or the second accommodating space from the cover separating structure are not turned enough to cause the upside down, thereby being beneficial to keeping the cover conveyor to continue to operate. Therefore, the height distance between the cover separating structure and the level of the cover stacked at the highest position is kept smaller than the longest width of the cover, and the operation efficiency of the cover conveyor is improved.

(3) Because the user can hold the lid in advance in a plurality of jigs, so the user need not keep by the lid conveyer in order to supply the replenishment lid at any time all the time. That is, the cover conveyor can effectively save labor and cost.

Please refer to fig. 1-2. Fig. 1 is a schematic perspective view illustrating a cover conveyer 100 according to an embodiment of the invention. Fig. 2 is a partial front view illustrating the cover conveyor 100 of fig. 1, in which the first suction device 140 is not lowered to suck the cover 200. In the present embodiment, as shown in fig. 1 to 2, a cover conveyor 100 includes a frame 110, a plurality of jigs 120, a first supporting device 130, a first suction device 140, and a cover separating structure 150. The jigs 120 are arranged along the first direction D1. The jig 120 includes a base 121 and a plurality of first limiting structures 122. The base 121 is movably connected to the frame 110 along a first direction D1, so that the jig 120 can move along the first direction D1 relative to the frame 110.

Please refer to fig. 3. Fig. 3 is a cross-sectional view along line A-A of fig. 2. In this embodiment, as shown in fig. 3, the base 121 of the jig 120 further has a first through hole H1, and the first limiting structures 122 are separated from each other and disposed on the base 121 around the first through hole H1 on average. As shown in fig. 2, the first limiting structures 122 extend along a second direction D2, and the second direction D2 is perpendicular to the first direction D1.

As shown in fig. 2 to 3, a first accommodating space S1 is defined between the first limiting structures 122, and the first accommodating space S1 is configured to allow the plurality of covers 200 to be stacked therein along the second direction D2. In the present embodiment, the cover 200 is a soft plastic cover. As described above, since the first limiting structures 122 are separated from each other, the user can clearly know the number of the covers 200 located in the first accommodating space S1, and the space between the first limiting structures 122 can at least partially protrude the circular cover 200, which is beneficial to limiting the positions of the covers 200 in the first accommodating space S1.

Furthermore, as shown in fig. 2 to 3, the first supporting device 130 is disposed on the frame 110 and configured to extend and retract along the second direction D2 in the corresponding first accommodating space S1 at least partially through the corresponding first through hole H1.

More specifically, as shown in fig. 2, the first supporting device 130 includes a fixed portion 131, a movable rod 132, and a supporting portion 133. The fixing portion 131 is connected to the frame 110. The movable rod 132 is at least partially disposed in the fixed portion 131 and configured to extend and retract along the second direction D2 relative to the fixed portion 131. The supporting portion 133 is disposed at an end of the movable rod 132 away from the fixed portion 131, and the supporting portion 133 is configured to support the cover 200.

In addition, as shown in fig. 2, the first suction device 140 is coupled to the frame and at least partially aligned with the first holding device 130, and the first suction device 140 is configured to move at least partially in the second direction D2.

Please refer to fig. 4. Fig. 4 is a cross-sectional view along line B-B of fig. 2. In this embodiment, as shown in fig. 4, the cover separating structure 150 has a first opening O1, the first opening O1 is configured to allow the first suction device 140 to at least partially pass through, and a shortest width WS of the first opening O1 is smaller than a longest width WL of the cover 200. Specifically, the longest width WL of the cover 200 is the diameter of the cover 200 having a circular shape.

In fact, as shown in fig. 3, the base 121 further has a plurality of second through holes H2, and the second through holes H2 are arranged along a third direction D3, and the third direction D3 is perpendicular to the first direction D1 and the second direction D2. The first through holes H1 and the corresponding second through holes H2 are arranged along the third direction D3, a first distance L1 is provided between the first through holes H1 and the adjacent second through holes H2, a second distance L2 is provided between the two adjacent second through holes H2, and the second distance L2 is the same as the first distance L1. In essence, the first through hole H1 is the same size as the second through hole H2.

Furthermore, as shown in fig. 2 to 3, the jig 120 further includes a plurality of second limiting structures 122', the second limiting structures 122' are separated from each other and are disposed on the base 121 around the corresponding second through holes H2, the second limiting structures 122 'extend along the second direction D2, the second limiting structures 122' define a plurality of second accommodating spaces S2, the second accommodating spaces S2 are respectively communicated with the corresponding second through holes H2, and the second accommodating spaces S2 are configured to enable a plurality of covers to be stacked therein along the second direction. In other words, the jig 120 can simultaneously accommodate multiple sets of stacked covers 200 in the first accommodating space S1 and the second accommodating space S2, so as to improve the operation efficiency of the cover conveyor 100. In essence, the second limiting structure 122' has the same size as the first limiting structure 122.

Correspondingly, as shown in fig. 2, the cover conveyer 100 further includes a plurality of second supporting devices 130 'and a plurality of second sucking devices 140'. The second supporting device 130' is disposed on the frame 110 and configured to extend and retract along the second direction D2 in the corresponding second accommodating space S2 at least partially through the corresponding second through hole H2. The second suction device 140' is coupled to the frame 110 and is at least partially aligned with the corresponding second holding device 130' along the second direction D2, and the second suction device 140' is configured to move at least partially along the second direction D2. Furthermore, as shown in fig. 4, the cover separating structure 150 has a plurality of second openings O2, and the second openings O2 are arranged and configured along the third direction D3 to allow the corresponding second suction devices 140' to at least partially pass through. In essence, the second support 130 'is identical in structure to the first support 130, and the second suction device 140' is identical in structure to the first suction device 140.

When the cover conveyor 100 is operated, as shown in fig. 2, the movable rods 132 of the first supporting device 130 and the second supporting device 130' extend along the second direction D2 relative to the fixed portion 131, so as to support the covers 200 supported by the supporting portions 133 in the first accommodating space S1 and the second accommodating space S2 toward the cover separating structure 150 until the highest cover 200 reaches a specific level R. It should be noted that, since the jig 120 has the first accommodating space S1 and the plurality of second accommodating spaces S2, the jig 120 can simultaneously provide a plurality of sets of the cover bodies 200 for the first suction device 140 and the second suction device 140' to extract, so as to improve the operation efficiency of the cover body conveyor 100. For example, in the present embodiment, as shown in fig. 2, the number of the first accommodating spaces S1 is one, and the number of the second accommodating spaces S2 is three, that is, the jig 120 can simultaneously provide four sets of the cover bodies 200 for the cover body conveyor 100 to operate. However, it should be understood that the number of the first accommodating space S1 and the plurality of the second accommodating spaces S2 in the jig 120 is merely illustrative, and is not intended to limit the present invention, and the number of the first accommodating space S1 and the plurality of the second accommodating spaces S2 should be set appropriately according to practical needs.

Please refer to fig. 5. Fig. 5 is a partial front view illustrating the cover conveyor 100 of fig. 1, in which the first suction device 140 and the second suction device 140' descend and suck the cover 200. In this embodiment, as shown in fig. 2 and 5, the cover conveyor 100 further includes a connection structure 145 and a moving device 160, wherein the connection structure 145 connects the second suction device 140 'and the first suction device 140, and the moving device 160 is connected between the frame 110 and the connection structure 145 and configured to move the connection structure 145 along the second direction D2 relative to the frame 110, so that the first suction device 140 and the second suction device 140' can move along the second direction D2 relative to the frame 110. When the top cover 200 in the first and second spaces S1 and S2 reaches the specific level R, the moving device 160 moves the first and

second suction devices

140 and 140 'to descend toward the cover 200 until the first and

second suction devices

140 and 140' reach the level R and contact the cover 200. At this time, the movable rods 132 of the first and second supporting devices 130 and 130 'further extend along the second direction D2 relative to the fixed portion 131, so that the first and

second suction devices

140 and 140' can firmly suck the cover 200.

In practical applications, as shown in fig. 2 and 5, the cover conveyer 100 further includes a sensing device 190 and a control device 195. The sensing device 190 is in signal connection with the first suction device 140 and the second suction device 140', and the control device 195 is electrically connected with the sensing device 190 and the first holding device 130 and the second holding device 130'. Specifically, the sensing device 190 is configured to sense the elastic displacement of the first suction device 140 and the second suction device 140 'when contacting the cover 200, and provide a signal to the control device 195 to allow the control device 195 to control the expansion and contraction of the first support device 130 and the second support device 130'. Furthermore, the sensing device 190 is further configured to sense whether the first suction device 140 and the second suction device 140 'are too high in displacement due to the pressing force when the first supporting device 130 and the second supporting device 130' are further extended. For example, the sensing device 190 may be a metal sensor, an electrical sensor, or a light sensor, but the invention is not limited thereto.

Please refer to fig. 6. Fig. 6 is a partial front view illustrating the cover conveyor 100 of fig. 1, in which the first suction device 140 and the second suction device 140' suck the cover 200 and lift the cover 200. In the present embodiment, after the first suction device 140 and the second suction device 140' firmly suck the cover 200, the moving device 160 moves the first suction device 140 and the second suction device 140' away from the jig 120, that is, the cover 200 sucked by the first suction device 140 and the second suction device 140' is lifted up and passes through the first opening O1 and the second opening O2 of the cover separating structure 150, as shown in fig. 6. As described above, since the shortest width WS of the first opening O1 (and the second opening O2) is smaller than the longest width WL of the cover 200, when the cover 200 passes through the first opening O1 and the second opening O2 of the cover separating structure 150, the cover 200 is blocked by the edges forming the first opening O1 and the second opening O2, resulting in deformation of the soft cover 200. In this way, when the cover 200 is stuck to another cover 200 or covers due to static electricity, the cover 200 or covers stuck to the cover 200 sucked by the first suction device 140 and the second suction device 140' are separated from the sucked cover 200 by the deformation of the cover 200. Therefore, the cover separating structure 150 can maintain the number of the covers 200 lifted by the first suction device 140 and the second suction device 140' at one piece, thereby effectively improving the operation efficiency of the cover conveyor 100.

It is noted that the height distance V between the cover separating structure 150 and the horizontal R is smaller than the longest width WL of the cover 200, i.e. smaller than the diameter of the cover 200 having a circular shape. In this way, when one or more covers 200 attached to the covers 200 absorbed by the first absorbing means 140 and the second absorbing means 140' are separated from the absorbed covers 200, one or more covers 200 falling from the cover separating structure 150 to the first accommodating space S1 or the second accommodating space S2 will not have enough space to turn upside down, so that the cover conveyor 100 is advantageously kept to continue to operate. Therefore, maintaining the height distance V between the cover separating structure 150 and the horizontal R smaller than the longest width WL of the cover 200 is advantageous to improve the operation efficiency of the cover conveyor 100.

Furthermore, as described above, since the jig 120 can move along the first direction D1 relative to the frame 110, when the cover 200 in the first accommodating space S1 and the second accommodating space S2 of a certain jig 120 is extracted by the first suction device 140 and the second suction device 140', that is, when the cover 200 is not in the first accommodating space S1 or the second accommodating space S2, the user can move the jig 120 along the first direction D1 and move the jig 120 adjacent to the accommodated cover 200 along the first direction D1 to the lower portion of the first suction device 140 and the second suction device 140', so that the cover conveyor 100 can continue to operate. Because the user can hold the cover 200 in the plurality of jigs 120 in advance, the user does not have to keep the cover conveyor 100 at all times to replenish the supply of the cover 200 at any time. That is, the cover conveyor 100 can effectively save labor and cost.

Please refer to fig. 7. Fig. 7 is a partial side view illustrating the drawing of fig. 6 along arrow C, in which the cover 200 sucked by the first suction device 140 (and the second suction device 140') is located above the receiving surface 172a of the receiving plate 172. In the present embodiment, the cover conveyor 100 further includes a collecting device 170. To simplify the drawing, the collection device 170 is not shown in fig. 2-6. As shown in fig. 7, the collecting device 170 includes a stopper 171 and a receiving plate 172. The stop portion 171 is connected to the frame 110 and has a stop surface 171a. The receiving plate 172 is movably connected to the stopper 171, and the receiving plate 172 has a receiving surface 172a, the receiving surface 172a being configured to be exposed to the stopper 171 or to be covered by the stopper 171. When the receiving surface 172a of the receiving plate 172 is exposed to the stop portion 171, the receiving surface 172a is adjacent to the stop surface 171a and is at least partially located between the first suction device 140 (and the second suction device 140') and the corresponding jig 120 (see fig. 1, 2, 5, and 6 for the jig 120).

Please refer to fig. 8. Fig. 8 is a schematic diagram illustrating the operation of the collecting device 170 of fig. 6, wherein the cover 200 is separated from the first suction device 140 (and the second suction device 140') and falls on the receiving surface 172a of the receiving plate 172. In the present embodiment, as shown in fig. 8, when the receiving surface 172a is exposed to the stopper 171, the receiving surface 172a is located below the first suction device 140 (and the second suction device 140'). When the first suction device 140 and the second suction device 140' stop sucking the cover 200, the cover 200 drops on the receiving surface 172a of the receiving plate 172.

Please refer to fig. 9. Fig. 9 is a schematic diagram illustrating the operation of the collecting device 170 of fig. 6, wherein the receiving plate 172 moves toward the stop portion 171 and the cover 200 touches the stop surface 171a of the stop portion 171. In the present embodiment, as shown in fig. 7 to 9, the cover conveyor 100 further includes a conveyor 180. The conveying device 180 is at least partially located at a side of the receiving plate 172 away from the stop portion 171, and is configured to support and convey the cover 200. To simplify the drawing, the conveyor 180 is not shown in fig. 2-6. In practical applications, the conveying device 180 may be a conveyor belt, but the invention is not limited thereto. When the cover 200 is dropped onto the receiving surface 172a of the receiving plate 172, the receiving plate 172 moves toward the stopping portion 171 so that the cover 200 touches the stopping surface 171a of the stopping portion 171. At this time, the position of the cover 200 corresponds to the conveyor 180.

Please refer to fig. 10. Fig. 10 is a schematic diagram illustrating the operation of the collecting device 170 of fig. 6, in which the receiving surface 172a is covered by the stop portion 171 and the cover 200 falls onto the conveying device 180. In the present embodiment, as shown in fig. 10, when the receiving surface 172a of the receiving plate 172 is covered by the stopper 171, the cover 200 is no longer supported by the receiving surface 172a, and the cover 200 falls onto the conveyor 180 and is conveyed to the next process location by the conveyor 180.
