[0068] The conveying push hook assembly of the present invention is applied to a step-type conveying line. The conveying push hook assembly unfolds during the pushing stroke, pushing the material to be conveyed forward. When returning, it automatically retracts when encountering the material to be conveyed, and resumes the unfolded state under the action of gravity when getting rid of the obstruction of the material to be conveyed. The conveying push hook assembly is in an unfolded state under normal conditions, and realizes step-type one-way conveying of the material to be conveyed under reciprocating horizontal drive without a return drive.

[0069] The step-type conveying line of the present invention is particularly suitable for the conveying of cotton bales in a cotton spinning production workshop. However, it should be noted that it can also be used to convey most of the raw materials of goods in the industrial production field.

[0070] Such as Figures 1 to 5 shown, Figure 1 is a three-dimensional structure diagram of an embodiment of the step-type conveying line of the present invention, Figure 2 and Figure 3 is a three-dimensional structure diagram of an embodiment of the conveying push hook assembly of the present invention, Figure 4 is a side view of an embodiment of the conveying push hook assembly of the present invention, Figure 5 is a use and installation state diagram of an embodiment of the conveying push hook assembly of the present invention.

[0071] The step-type conveying line 10 of the present invention includes a conveying push hook assembly 100, a moving mechanism 200 and a conveying main body 300. Among them, the conveying push hook assembly 100 is connected to the moving mechanism 200, the moving mechanism 200 is connected to the conveying main body 300, and the moving mechanism 200 drives the conveying push hook assembly 100 to reciprocate along the conveying direction X on the conveying main body 300, so that the conveying push hook assembly 100 drives the material to be conveyed to be transported step by step along the conveying direction X.

[0072] The moving mechanism 200 drives the conveying push hook assembly 100 to reciprocate, having a forward stroke and a return stroke. During the forward stroke when the moving mechanism 200 drives the conveying push hook assembly 100 to move forward along the conveying direction X, the conveying push hook assembly 100 is in the pushing position, and the moving mechanism 200 drives the conveying push hook assembly 100 to push the material to be conveyed along the conveying direction X, so that the material to be conveyed is conveyed along the conveying direction X. During the return stroke when the moving mechanism 200 drives the conveying push hook assembly 100 to move backward along the conveying direction X, first, the conveying push hook assembly 100 rotates from the pushing position to the returning position due to the obstruction of the material to be conveyed when moving backward, and rotates from the returning position to the pushing position under the action of gravity when the obstruction disappears, preparing for the next step-by-step pushing.

[0073] Among them, there are multiple conveying push hook assemblies 100, which are connected to the moving mechanism 200 at intervals. Each conveying push hook assembly 100 is used to convey one material to be conveyed, for example.

[0074] Such as Figures 2 to 5As shown in the figure, the conveying push hook assembly 100 of the present invention includes a mounting base 110 and a push hook 120. Among them, the mounting base 110 is connected to the moving mechanism 200, and a first limiting structure 130 and a second limiting structure 140 are connected thereto. The push hook 120 is rotatably connected to the mounting base 110 and is inclined along the conveying direction X, and has a pushing stroke position limited by the first limiting structure 130 and a return stroke position limited by the second limiting structure 140 during the rotation process.

[0075] As Figure 3 and Figure 4 shown, the push hook 120 is inclined along the conveying direction X. The horizontal height of the front of the push hook 120 along the conveying direction X is lower than the horizontal height of the rear of the push hook 120 along the conveying direction X. The first limiting structure 130 is located at the rear along the conveying direction X, and the second limiting structure 140 is located at the front along the conveying direction X. Under normal conditions, the push hook 120 droops due to gravity and is located at the pushing stroke position under the limitation of the first limiting mechanism 130, showing an unfolded state. When an external force acts on the push hook 120, for example, during the return journey when the moving mechanism 200 drives the conveying push hook assembly 100 to retreat along the conveying direction X, combined with Figure 1 , the push hook 120 is blocked by the material to be conveyed and rotates counterclockwise along the direction P from the pushing stroke position, and is limited by the second limiting mechanism 140 to be in the return stroke position, showing a retracted state. When the push hook 120 retreats to a position where there is no action of the material to be conveyed, the push hook 120 rotates clockwise along the direction Q under the action of gravity and rotates from the return stroke position to the pushing stroke position, that is, returns from the retracted state to the unfolded state.

[0076] Specifically, the push hook 120 includes a push hook arm 121 and a first end 122 and a second end 123 respectively located at both ends of the push hook arm 121. The first end 121 is rotatably connected to the mounting base 110, and the second end 123 is far from the mounting base 110. That is to say, the first end 122 forms a rotational connection with the mounting base 110, and the second end 123 is used to push against the material to be conveyed to convey the material to be conveyed.

[0077] Among them, the first end 122 of the push hook 120 is inclined along the conveying direction X. The horizontal height of the part of the first end 122 close to the first limiting structure 130 is lower than the horizontal height of the part of the first end 122 close to the second limiting structure 140. That is, under normal conditions, the push hook 120 is in the unfolded state at the pushing stroke position under the action of gravity.

[0078] Furthermore, the push hook arm 121 of the push hook 120 includes a limiting section 1211 and a pushing section 1212 connected at an angle. Among them, the limiting section 1211 is close to the mounting base 110, and the pushing section 1212 is at the other end far from the mounting base 110. The pushing section 1212 corresponds to the material to be conveyed and is used to push and convey the material to be conveyed.

[0079] Due to the limitation of the first limiting structure 130 and the second limiting structure 140, the pushing hook 120 can only rotate within the range defined by the first limiting structure 130 and the second limiting structure 140. When the pushing hook 120 is in the pushing stroke position, the limiting section 1211 is limited by the first limiting structure 130, and when the pushing hook 120 is in the return stroke position, the limiting section 1211 is limited by the second limiting structure 140.

[0080] In an embodiment of the present invention, when the pushing hook 120 is in the pushing stroke position, the pushing section 1212 is perpendicular to the conveying direction X, which is beneficial for pushing the material to be conveyed.

[0081] In an embodiment of the present invention, the pushing hook 120 further includes a pushing hook contact head 124 and a pushing hook return shaft 125. The pushing hook contact head 124 is connected to the second end portion 123 through the pushing hook return shaft 125. The setting of the pushing hook contact head 124 is beneficial for the pushing hook 120 to push the material to be conveyed and for the pushing hook 120 to move relative to the material to be conveyed on the one hand, and on the other hand, it increases the weight of the second end portion 123, which is beneficial for the pushing hook 120 to return to its position.

[0082] In an embodiment of the present invention, as Figure 4 shown, the mounting seat 110 further includes an adjusting plate 111. The first limiting structure 130, the first end portion 123 of the pushing hook 120, and the second limiting structure 140 are respectively connected to the adjusting plate 111 along the conveying direction X. Among them, the adjusting plate 111 is inclinedly mounted on the moving mechanism 200, so that the first end portion 123 of the pushing hook 120 is inclinedly arranged. Specifically, the horizontal height of the adjusting plate 111 where the second limiting structure 140 is located is higher than the horizontal height of the adjusting plate 111 where the first limiting structure 130 is located, or in other words, the adjusting plate 111 has an angle relative to the horizontal plane The horizontal height of the front end of the adjusting plate 111 along the conveying direction X is higher than the horizontal height of the rear end.

[0083] Correspondingly, the horizontal height of the front end of the first end portion 123 of the pushing hook 120 mounted on the adjusting plate 111 along the conveying direction X is higher than the horizontal height of the rear end. Under normal conditions, due to the action of gravity, the pushing hook 120 abuts against the first limiting structure 130 at the lower end and is in the unfolded state of the pushing stroke position.

[0084] Specifically, the mounting seat 110 further includes a mounting plate 112. The mounting plate 112 is connected to the moving mechanism 200, and the adjusting plate 111 is inclinedly mounted on the moving mechanism 200 through the mounting plate 112. Generally speaking, the mounting plate 112 is horizontally arranged, so the adjusting plate 111 has an angle with the mounting plate 112

[0085] In an embodiment of the present invention, the first limiting structure 130 includes a first height adjusting member, and the second limiting structure 140 includes a second height adjusting member. Specifically, the first height adjusting member and the second height adjusting member are, for example, height adjusting screws. By adjusting the heights of the height adjusting screws on both sides, the inclination angle of the adjusting plate 111 can be conveniently adjusted.

[0086] Combined with Figure 3 and Figure 5 , the adjusting plate 111 of the mounting seat 110 is mounted on the moving member 210 of the moving mechanism 200 through the mounting plate 112. The hook arm 121 of the push hook 120 can rotate around the hook arm rotation shaft 126, and the push hook contact 124 can move around the contact rotation shaft 125. The first limiting structure 130 and the second limiting structure 140 limit the swinging range of the hook arm 121, and can adjust the adjusting plate 111 and the mounting plate 112 to form a certain angle, so that the hook arm 121 of the push hook 120 is in an unfolded state under the action of gravity, which is also the state of pushing the material to be conveyed during the pushing stroke, and the rotation of the push hook is limited by the first limiting structure 130. During the return stroke, the push hook contact 124 touches the material to be conveyed and rotates around the push hook swing arm 125 to a retracted state. After bypassing the material to be conveyed, the push hook 120 returns to the unfolded state under the action of gravity.

[0087] In the present invention, as Figure 1 , Figure 7 and Figure 8 shown, Figure 7 and Figure 8 are partial perspective structural diagrams of an embodiment of the step-type conveying line of the present invention. The conveying push hook assembly 100 and the moving mechanism 200 can be arranged on one side of the conveying main body 300 along the conveying direction X. Specifically, the moving mechanism 200 further includes a cylinder 220, a slide rail 230, and a connecting member 240. The moving member 210 is connected to the slide rail 230 through an internal slider to linearly move along the slide rail 230. The mounting plate 112 of the conveying push hook assembly 100 is connected to the moving member 210. The cylinder 220 is connected to the moving member 210 through the connecting member 240, and the cylinder 220 drives the conveying push hook assembly 100 to reciprocate through the moving member 210 for pushing. In this embodiment, the conveying push hook assembly 100 and the moving mechanism 200 are only arranged on one side of the conveying main body 300, and the conveying push hook assembly 100 pushes the material to be conveyed to perform step-type conveying in the conveying channel of the conveying line body 300.

[0088] As Figure 1 , Figure 9 and Figure 10 shown, Figure 9 and Figure 10FIG. 0 is a partial perspective view of an embodiment of the step conveyor line of the present invention, showing the structure of the conveying push hook assemblies and the moving mechanism arranged on both sides of the conveying main body. The conveying push hook assemblies and the moving mechanism can be arranged on both sides of the conveying main body along the conveying direction X.

[0089] Specifically, the conveying push hook assemblies include conveying push hook assemblies 100a and 100b. The conveying push hook assembly 100a is arranged on the first side 310 of the conveying main body 300, and the conveying push hook assembly 100b is arranged on the second side 320 of the conveying main body 300.

[0090] The moving mechanism 200a includes moving members 210a, 210b, a cylinder 220, connecting members 240a and 240b. Among them, the moving members 210a and 210b are respectively arranged on the first side 310 and the second side 320. Synchronization can be achieved by a chain and a transmission shaft to the other side for horizontal movement synchronization control. For example, the moving mechanism 200a further includes chains 250a, 250b and a transmission shaft 260. The transmission shaft 260 passes from the first side 310 to the second side 320. The chain 250a is connected to the transmission shaft 260 on the first side 310, and the chain 250b is connected to the transmission shaft 260 on the second side 320. Among them, as Figure 8 shown, the cylinder 220 is arranged on the first side 310, and the cylinder 220 is connected to both the moving member 210a and the chain 250a through the connecting member 240a. As Figure 9 shown, on the second side 320, the moving member 210b and the chain 250b are connected through the connecting member 240b.

[0091] When the cylinder 220 moves to drive the moving member 210a to reciprocate, it drives the moving member 210b to reciprocate synchronously through chain drive, so that the conveying push hook assemblies 100a and 100b located on the first side 310 and the second side 320 reciprocate synchronously. In this embodiment, the conveying push hook assemblies 100a, 100b and the moving mechanism 200a are arranged on both sides of the conveying main body 300, with a greater pushing force and more stable conveying.

[0092] As Figure 6 shown, Figure 6Stereoscopic structure diagram of an embodiment of the step conveyor line of the present invention. The step conveyor line 10 of the present invention further includes a steering hook 400. The conveying main body 300 includes a vertically connected conveying main body 3001 and a conveying main body 3002. The steering hook 400 is arranged on the moving mechanism at the connection of the conveying main body 3001 and the conveying main body 3002. Specifically, a moving mechanism 2001 and a conveying push hook assembly 1001 are connected to the conveying main body 3001, a moving mechanism 2002 and a conveying push hook assembly 1002 are connected to the conveying main body 3002, and the steering hook 400 is arranged on the moving mechanism 2002 at the connecting corner of the conveying main body 3001 and the conveying main body 3002. The material to be conveyed is step-conveyed along the conveying direction X1 on the conveying main body 3001 through the moving mechanism 2001 and the conveying push hook assembly 1001 until it reaches the corner. Then, it is turned by the steering hook 400, the moving mechanism 2002, and the conveying push hook assembly 1002, and is step-conveyed along the conveying direction X2 on the conveying main body 3002.

[0093] When the present invention is used in the logistics system of the cotton spinning system, the material to be conveyed is, for example, a bale, as Figure 1 shown, the step conveyor line 10 further includes a bale positioning member 500 for fixing the bale. There are multiple bale positioning members 500, which are sequentially arranged at the inner bottom of the conveying main body 300, and the positions of the bale positioning members 500 correspond to those of the conveying push hook assembly 100, that is, the conveying push hook assembly 100 step-pushes the bale out of the bale positioning member 500 and advances it to the next bale positioning member 500.

[0094] The step conveyor line 10 of the present invention further includes a counting sensor 600 for counting the bales.

[0095] Of course, 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, but these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present invention.
