[0061] The transfer and conveying system of the present invention adopts one-way step-by-step conveying and can convey most of the workpieces or raw materials of goods in the industrial production field. For example, in the cotton spinning industrial production, the transfer and conveying system of the present invention can be used to convey full and empty cotton spinning cans, which can realize the automation of the logistics in the production workshop, reduce the dependence on labor in cotton spinning production, reduce the labor intensity, improve the efficiency, reduce the product cost, and increase the economic benefits of the product. Of course, the present invention is not limited to being applied to cotton spinning industrial production. The following only takes the application to the conveying of full and empty cotton spinning cans as an example.

[0062] As Figure 1 and Figure 2 shown, the transfer and conveying system of the present invention includes a transfer body 100, a tray 200 and a transfer and pushing component 300. The tray 200 is placed on the transfer body 100, and the transfer and pushing component 300 is connected to the transfer body 100. There are multiple trays 200, which are used to place workpieces or raw materials of goods such as cotton spinning cans. The transfer and pushing component 300 pushes or drags the tray 200 to move forward step by step in one direction along the transfer body 100.

[0063] Specifically, the shifting and pushing component 300 includes a moving part 310 and a pushing part 320. The moving part 310 is reciprocally movably connected to the transfer body 100, and the pushing part 320 is rotatably connected to the moving part 310. Among them, the moving part 310 has a forward stroke with step-by-step driving and a return stroke with step-by-step return. As Figure 1 shown, the moving part 310 advances a certain distance along the direction X. As Figure 2 shown, and then advances a certain distance along the opposite direction Y of this direction, that is, the moving part 310 drives the pushing part 320 to reciprocally move within a certain distance.

[0064] The moving part 310 includes a limit protrusion 311, and the pushing part 320 includes a pushing portion 321 and a limit portion 322. Among them, the pushing part 320 is rotatably connected to the moving part 310 and has a forward stroke state and a return stroke state. As shown in FIG. 1, in the forward stroke state, the moving part 310 drives the pushing part 320 to move along the X direction. At this time, the limit portion 322 of the pushing part 320 corresponds to the limit protrusion 311 of the moving part 310 to limit the rotation of the pushing part 320, and the pushing portion 321 of the pushing part 320 corresponds to the tray 200 to push the tray 200 to move forward on the transfer body 100. As Figure 2 shown, in the return stroke state, the whole pushing part 320 rotates and falls down, that is, the pushing portion 321 is located below the tray 200. At this time, the limit portion 322 is away from the limit protrusion 311.

[0065] The transfer and conveying system of the present invention is a one-way step-by-step conveying, and the moving part drives the pushing part to reciprocally move. In the forward stroke, the pushing part pushes the tray carrying the strip barrel forward. In the return stroke, the pushing part rotates and falls to retract, so it is a one-way conveying.

[0066] In an embodiment of the present invention, the whole pushing part 320 is a push hook in a triangular shape. The pushing portion 321 is formed at the first corner 320a of the triangle, and the limit portion 322 is formed at the second corner 320b and the third corner 320c of the triangle. The second corner 320b and the third corner 320c where the limit portion 322 is located are in the lower position under the action of gravity, and the first corner 320b where the pushing portion 321 is located is lifted upward. Of course, the pushing part 320 can also be of other shapes, and the present invention has no limitation.

[0067] In the forward stroke of the transfer and conveying system of the present invention, since the limit protrusion 311 of the moving part 310 is opposite to the limit portion 322 of the pushing part 320, it blocks the rotation of the pushing part 320, and the pushing portion 321 of the pushing part 320 pushes the tray forward. In the return stroke, due to the lack of limitation, the pushing portion 321 of the pushing part 320 rotates after hitting the tray and cannot push the tray back, thus realizing the one-way conveying of the tray.

[0068] The pusher 320 further includes a rotating shaft portion 323. The pusher 320 is rotatably connected to the moving member 310 through the rotating shaft portion 323. The whole pusher 320 can rotate around the rotating shaft portion 323, and the pushing portion 321 and the limiting portion 322 are respectively located on both sides of the rotating shaft portion 323.

[0069] In one embodiment, in the return stroke state, the pushing portion 321 of the pusher 320 is blocked by the tray, causing the whole pusher 320 to rotate and fall. Specifically, in combination with Figure 1 and Figure 2 , in the forward stroke state, the moving member 310 drives the pusher 320 to push the previous tray 200' forward a distance along the direction X. In the return stroke state, the moving member drives the pusher 320 to move along the direction Y. During this process, the pushing portion 321 of the pusher 320 is blocked by the subsequent tray 200". At this time, the limiting protrusion 311 does not limit the limiting portion 322 of the pusher 320. Therefore, the pusher 320 rotates counterclockwise and moves along the direction Y below the subsequent tray 200".

[0070] As Figure 3 shown, in one embodiment of the present invention, the transfer conveying system further includes a return stroke trigger 400. In the return stroke state, the limiting portion 322 of the pusher 320 is triggered by the return stroke trigger 400, causing the whole pusher 320 to rotate.

[0071] Specifically, the return stroke trigger 400 includes a trigger limiting block, and the pusher 320 includes a trigger switch 324. The trigger limiting block is connected to the transfer body 100, and the trigger switch 324 is connected to the limiting portion 322 of the pusher 320. Specifically, the trigger switch 324 is connected to the third corner portion 320c of the pusher 320.

[0072] In this embodiment, the trigger limiting block is triangular, and the trigger switch 324 is a bearing member. During the return stroke, the moving member 310 drives the pusher 320 to move along the direction Y. The trigger switch 324 on the third corner portion 320c of the pusher 320 moves along the inclined surface of the trigger limiting block, so that the whole pusher 320 rotates counterclockwise, and the pushing portion 310 rotates and falls until it is below the transfer body 100.

[0073] By setting the return stroke trigger 400, the present invention can also make the pusher 320 rotate and fall when there is no tray blocking during the return stroke, and will not drag or hook the tray when there is a tray during the return stroke. The return stroke trigger 400 of the present invention is generally arranged at the turning position in the line body, and the following embodiments will illustrate this.

[0074] As Figure 4 and Figure 5As shown, the transfer body 100 of the transfer and conveying system of the present invention includes a first transfer body 110 and a second transfer body 120, and the width of the second transfer body 120 is greater than the width of the first transfer body 110.

[0075] As Figure 6 and Figure 7 shown, the tray 200 cooperating with the transfer and conveying system of the present invention is rectangular and can hold two bobbins. For the two forms of horizontal transfer trays and vertical transfer trays, the transfer body 100 of the transfer and conveying system of the present invention has two types: narrow and wide. Among them, the first transfer body 110 is a narrow transfer body for vertically conveying trays, and the second transfer body 120 is a wide transfer body for horizontally conveying trays. The narrow and wide first transfer body 110 and second transfer body 120 can cooperate with the tray 200 to meet various requirements such as straight line, turning, merging, and diverting of bobbin conveying.

[0076] As Figure 8 and Figure 9 shown, the first transfer body 110 is suitable for vertically conveying the tray 200. Generally speaking, there are multiple sets of transfer and pushing components 300, and the transfer and pushing components 300 are connected to the middle of the first transfer body 110. The second transfer body 120 is suitable for horizontally conveying the tray 200. Generally speaking, there are multiple sets of transfer and pushing components 300, and the transfer and pushing components 300 are connected to both sides of the second transfer body 120. In this embodiment, the pushing members 320 on both sides are connected to the same moving member 310, which is not limited in the present invention. In the line body composed of the first transfer body 110 and the second transfer body 120, each transfer body has different combination forms according to needs.

[0077] As Figure 6 and Figure 7 shown, the tray 200 includes a bottom surface 210 and a bearing surface 220. The bottom surface 210 is the surface corresponding to the transfer body 100 and facing the transfer body 100, and the bearing surface 220 is the upward surface opposite to the bottom surface 210. The bearing surface 220 includes a fixing portion 221 corresponding to the shape of the bottom of the bobbin for placing and fixing the bobbin.

[0078] Among them, the bottom surface 210 is provided with a groove 230 corresponding to the pushing portion 321 of the pushing member 320. Specifically, the groove 230 includes a first groove 231, a second groove 232, a third groove 233, and a fourth groove 234, and the first groove 231, the second groove 232, the third groove 233, and the fourth groove 234 are respectively multiple. Among them, the first groove 231 and the second groove 232 intersect in a cross shape. The third groove 233 and the fourth groove 234 are provided at the edge of the bottom surface 320. The third groove 233 is located on the extension line of the first groove 231, and the fourth groove 234 is located on the extension line of the second groove 232.

[0079] Combined Figures 4 to 7 , the tray 200 in the longitudinal direction has a long side and a short side. Among them, the first groove 231 is arranged along the middle of the short side parallel to the long side of the tray 200. The first groove 231 and the third groove 233 located on the extension line of the first groove 231 correspond to the pushing part 321 of the transfer assembly arranged in the middle of the first transfer body 110. The second groove 232 is parallel to the short side of the tray 200, and there are two second grooves 232 which are symmetrically arranged along the long side of the tray 200. The second groove 232 and the fourth groove 234 located on the extension line of the second groove 232 correspond to the pushing parts 321 of the transfer assemblies arranged on both sides of the second transfer body 120.

[0080] When two narrow transfer bodies are connected, as Figure 10 shown, that is, the first transfer body 110' is connected to the first transfer body 110". At this time, the pushing part 321 of the transfer assembly connected to the first transfer body 110' pushes the third groove 233 at the edge of the short side of the tray, so that the tray moves forward from the first transfer body 110' to the first transfer body 110".

[0081] When two wide transfer bodies are connected, as Figure 11 shown, that is, the second transfer body 120' is connected to the second transfer body 120". At this time, the pushing parts 321 of the transfer assemblies connected to the second transfer body 120' respectively push the two fourth grooves 234 at the edge of the long side of the tray, so that the tray moves forward from the second transfer body 120' to the second transfer body 120".

[0082] When a narrow and a wide transfer body are connected, as Figure 12 shown, the first transfer bodies 110a, 110b, 110c, 110d are respectively connected to the second transfer body 120. At this time, the first transfer body 110a to the second transfer body 120 is a turn at the L-shaped opening, and the first transfer body 110b to the second transfer body 120 is a turn at the T-shaped opening. Both of these are pushed by the pushing part 321 of the transfer assembly connected to the narrow transfer bodies (the first transfer bodies 110a, 110b) to push the tray onto the wide transfer body (the second transfer body 120). The second transfer body 120 to the first transfer body 110c is a turn at the T-shaped opening, and the second transfer body 120 to the first transfer body 110d is a turn at the L-shaped opening. Both of these hook out the tray from the wide transfer body (the second transfer body 120) through the pushing part 321 of the transfer assembly connected to the narrow transfer bodies (the first transfer bodies 110c, 110d).

[0083] Specifically, in the L-shaped and T-shaped steering from the narrow transfer body to the wide transfer body, the pushing part 321 of the transfer and pushing assembly connected to the first transfer bodies 110a and 110b pushes the third groove 233 at the short-side edge of the tray, causing the tray to move forward from the first transfer bodies 110a and 110b to the second transfer body 120.

[0084] In the L-shaped and T-shaped steering from the wide transfer body to the narrow transfer body, the pushing part 321 of the transfer and pushing assembly connected to the first transfer bodies 110c and 110d hooks the first groove 231 of the tray, causing the tray to move forward from the second transfer body 120 to the first transfer bodies 110c and 110d.

[0085] In addition, during the L-shaped and T-shaped commutation, since the tray will change the transfer body, the pushing part 321 of the transfer and pushing assembly on the wide transfer body will drop, enabling the tray to be pushed in or hooked out. Therefore, combined Figure 3 , in an embodiment of the present invention, a return trigger 400 is provided on the wide transfer body (the second transfer body) at all steering positions. At the steering position, the trigger switch 324 of the transfer and pushing assembly on the wide transfer body touches the return trigger 400 at the steering position, thereby causing the transfer and pushing assembly to rotate and the pushing part 321 to drop and retract.

[0086] In addition, each transfer body is also provided with an occupancy switch detection device for detecting whether there is a tray on the transfer body, and an information recognition device for recognizing the batch and status of the barrels on the tray.

[0087] Certainly, the present invention can also have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention. However, these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present invention.
