Description

Technical Field

[0001] The invention relates to the technical field of automatic painting line hoisting, and in particular to an automatic painting line hoisting device. Background Art

[0002] Automatic spray painting line is a modern spraying equipment that integrates pre-treatment, drying, spraying, curing, automatic conveying system and computer control technologies. It is widely used in various industrial fields to provide high-quality surface coatings for products. For example, spray painting the components of laboratory equipment can play a protective and aesthetic role.

[0003] At present, a suspended automatic spray painting line is generally used to transport and spray the objects to be sprayed. Before transportation, a sling is usually used to hang the objects to be sprayed on the transport line of the automatic spray painting line, and then the transport line transports the objects to be sprayed to the painting station.

[0004] However, in production practice, it is first necessary to pre-hang the sling on the transport line, and then hang the object to be sprayed on the sling. These two steps require different operators to perform the operations in chronological order, which has a high labor cost. In addition, since the transport line is in continuous motion, the operators are prone to fatigue from the long-term coordinated operations of mounting the sling and mounting the object to be sprayed. In particular, when the rhythm of mounting the sling does not continue to follow the movement of the track, the operation of mounting the object to be sprayed cannot be carried out smoothly, thereby affecting the production progress. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide an automatic online device for hanging equipment of an automatic painting line, which aims to automatically hang the hanging equipment on the spraying production line, reduce personnel configuration and improve hanging efficiency.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0043] Please refer to Figures 1 to 11, is an automatic painting line hanger automatic online device provided by the present invention, the automatic painting line includes a transport line 100, and the transport line 100 is provided with a first mounting part for mounting a hanger 200 at intervals along its extension direction, and the two ends of the hanger 200 in the length direction are respectively provided with a first hook head 210 and a second hook head 220 that can be mounted with the first mounting part, and the first hook head 210 is used to mount the object to be sprayed. The automatic painting line hanger automatic online device includes a circular cylinder 300, a transport trough 400, a push mechanism 500, a mounting assembly 600, and a collection assembly 700.

[0044] The circular cylinder 300 is provided with a first accommodating cavity 310, a first opening 320 communicating with the first accommodating cavity 310, a second accommodating cavity 330, and a second opening 340 communicating with the second accommodating cavity 330. The sling 200 is assembled in the circular cylinder 300. Specifically, the sling 200 is clamped in the first accommodating cavity 310, the second hook 220 is located outside the first accommodating cavity 310, and the second hook 220 is close to the first opening 320.

[0045] The transport trough 400 is used to hold the circular cylinder 300. The transport trough 400 is provided with a feed end 410 and a discharge end 420, and a guide groove 430 matching the second hook head 220. When the circular cylinder 300 enters the transport trough 400 from the feed end 410, the second hook head 220 is limited to move in the guide groove 430 to prevent the circular cylinder 300 from rotating.

[0046] The pushing mechanism 500 is used to push the circular cylinder 300 from the feeding end 410 to the discharging end 420 , so that the circular cylinder 300 carried in the transport trough 400 is moved out from the discharging end 420 in sequence.

[0047] The mounting assembly 600 is arranged on the side of the discharge end 420, and is used for movably connecting the circular cylinder 300 transported from the transport trough 400. Specifically, the circular cylinder 300 can rotate relative to the mounting assembly 600, and after a certain degree of force is applied, the circular cylinder 300 can be separated from the mounting assembly 600. In this way, when the second hook head 220 is mounted on the first mounting part, the first mounting part in a moving state can drive the circular cylinder 300 to deflect, so that when the first mounting part continues to move away from the circular cylinder 300, the sling 200 can be smoothly pulled out of the first accommodating cavity 310, and at the same time, the circular cylinder after being moved out of the sling 200 is separated from the mounting assembly 600 by applying force, so that the next circular cylinder 300 can be movably mounted on the mounting assembly 600.

[0048] The collecting assembly 700 includes a third hook 710, a trigger assembly 720 and a first driving mechanism 730. The third hook 710 is movably arranged in the second accommodating chamber 330. Specifically, when the transport trough 400 transports the circular cylinder 300, the third hook 710 can be completely received in the second accommodating chamber 330 to avoid affecting the transportation. When the circular cylinder 300 is collected to prepare for the hanging of the next circular cylinder 300, the third hook 710 moves out of the second accommodating chamber 330 to separate the circular cylinder 300 from the mounting assembly 600. The trigger assembly 720 is arranged in the second accommodating chamber 330, and the trigger assembly 720 is connected to the third hook 710 in a transmission manner. The first driving mechanism 730 is provided with a second hanging part that can be hung with the third hook 710. When the first driving mechanism 730 is in a working state, the first driving mechanism 730 separates the circular cylinder 300 from the mounting assembly 600 through the hanging cooperation between the second hanging part and the third hook 710. Optionally, the first driving mechanism 730 may use a telescopic motor, and a hanging ring for hanging the third hook 710 is provided on the telescopic shaft of the telescopic motor.

[0049] In this embodiment, when the first mounting part mounts the second hook 220, the first mounting part pulls the circular cylinder 300 to rotate relative to the mounting assembly 600, and the circular cylinder 300 is transformed from a vertical state to an inclined state, and at the same time, the first mounting part gradually pulls the circular cylinder 300 out of the first accommodating cavity 310 through the second hook 220. Specifically, in the process of gradually withdrawing the sling 200 from the first accommodating cavity 310, the first hook 210 gradually approaches the trigger assembly 720, and the trigger assembly 720 is in a state of locking the third hook 710. When the first hook 210 passes the trigger assembly 720, the trigger assembly 720 is in a state of separating the third hook 710, and the third hook 710 extends out of the second accommodating cavity 330 from the second opening 340 under the action of gravity. When the sling 200 is pulled out from the first accommodating cavity 310, under the combined action of gravity and the mounting assembly 600, the circular cylinder 300 rotates from an inclined state to a vertical state. When the circular cylinder 300 rotates to a vertical state, the third hook head 710 is mounted on the second mounting portion, and then the first driving mechanism 730 is activated and applies force until the circular cylinder 300 is detached from the mounting assembly 600.

[0050] In some optional embodiments, such as Figures 2 to 4 , Figure 7 As shown, the mounting assembly 600 includes a surrounding plate 610 , a first rotating shaft 620 , an opening and closing mechanism 630 , and two sets of clamping plate assemblies 640 .

[0051] The enclosure 610 is provided with an avoidance hole 611 matching the discharge end 420, so that the circular cylinder 300 can smoothly pass through the avoidance hole 611 and enter the area surrounded by the enclosure 610. The first rotating shaft 620 is rotatably arranged on the enclosure 610, and the first rotating shaft 620 is located in the area surrounded by the enclosure 610. In addition, the rotation axis of the first rotating shaft 620 is parallel to the discharge direction of the discharge end 420. The side wall of the circular cylinder 300 is provided with a card interface 350 matching the first rotating shaft 620. When the circular cylinder 300 passes through the avoidance hole 611 and enters the area surrounded by the enclosure 610, the first rotating shaft 620 is carded in the card interface 350. At the same time, the side wall of the circular cylinder 300 is also provided with a slide groove 360 ​​connected to the card interface 350, the slide groove 360 ​​matches the width of the first rotating shaft 620, and the slide groove 360 ​​extends to the end of the circular cylinder 300 close to the first opening 320, so that after the first rotating shaft 620 and the card interface 350 are in contact and engaged, the first rotating shaft 620 can be moved out of the card interface 350 through the slide groove 360, so as to achieve the purpose of the circular cylinder 300 being separated. The opening and closing mechanism 630 is provided in the card interface 350, and is used to lock and separate the card interface 350 and the first rotating shaft 620. The two groups of clamping plate assemblies 640 are arranged opposite to each other, and the two groups of clamping plate assemblies 640 cooperate with each other to clamp the circular cylinder 300 in the discharge direction parallel to the discharge end 420, so that after the circular cylinder 300 passes through the avoidance hole 611 and enters the area enclosed by the enclosure 610, it can be clamped by the clamping plate assemblies 640 to prevent the impact force generated when the first mounting part mounts the second hook head 220 from causing the position of the circular cylinder 300 to deviate, thereby causing the mounting failure.

[0052] In this embodiment, when the circular cylinder 300 rotates relative to the enclosure 610, the two groups of clamping plate assemblies 640 approach or move away from each other. Specifically, when the first mounting portion mounts the second hook head 220, the circular cylinder 300 changes from a vertical state to an inclined state, and the circular cylinder 300 applies a thrust to the two groups of clamping plate assemblies 640 on both sides thereof. Under the action of the thrust, the two groups of clamping plate assemblies 640 move away from each other, but the two groups of clamping plate assemblies 640 always clamp the circular cylinder 300 in a discharge direction parallel to the discharge end 420 to ensure the stability of the hanging process; when the sling 200 is pulled out of the first accommodating cavity 310, the circular cylinder 300 changes from a vertical state to an inclined state. Since the first mounting portion does not apply a force to the circular cylinder 300, Under the combined action of the gravity of the circular cylinder 300 and the clamping force of the two sets of clamping plate assemblies 640, the two sets of clamping plate assemblies 640 approach each other until the circular cylinder 300 changes from the inclined state to the vertical state, and when the circular cylinder 300 rotates to the vertical state, the third hook 710 is mounted on the second mounting portion; thereafter, under the action of the first driving mechanism 730, the opening and closing mechanism 630 separates the card interface 350 from the first rotating shaft 620, so that the first rotating shaft 620 moves along the extending direction of the slide slot 360 until it moves out of the card interface 350, and the circular cylinder 300 is detached from the enclosure 610. Preferably, in order to ensure that the card interface 350 and the first rotating shaft 620 can always maintain a relatively static state, the card interface 350 can be set to a polygonal shape, such as a quadrilateral card interface 350, and a corresponding polygonal clamping area is set on the first rotating shaft 620.

[0053] In addition, it should be noted that by reasonably setting the depth of the card interface 350, when the circular cylinder 300 has not yet completely entered the area enclosed by the enclosure 610 from the avoidance hole 611, the front end of the first rotating shaft 620 can be inserted into the outermost edge of the card interface 350, thereby ensuring that the first rotating shaft 620 is accurately inserted into the card interface 350.

[0054] In addition, it should be noted that, in the process of the circular cylinder 300 passing through the avoidance hole 611 and entering the area surrounded by the enclosure 610, the circular cylinder 300 may rotate, thereby causing the second hook head 220 on the circular cylinder 300 to be unable to align with the first mounting portion to be mounted, and causing the third hook head 710 on the circular cylinder 300 to be unable to align with the second mounting portion to be mounted, and the guide groove 430 extends a portion toward the enclosure 610, and the length of the portion is equal to the thickness of the avoidance hole 611. At the same time, in order to enable the circular cylinder 300 to be smoothly clamped on the first rotating shaft 620, the area surrounded by the enclosure 610 matches the diameter of the circular cylinder 300.

[0055] In some optional embodiments, such as Figure 8As shown, the third hook 710 is slidably disposed in the second accommodating cavity 330. Optionally, a slide groove (not shown in the drawings) can be provided on the inner side wall of the second accommodating cavity 330. The third hook 710 is limited in the slide groove and can move in the slide groove. The third hook 710 is provided with a clamping block 711. The trigger assembly 720 includes a clamping plate 721, a first elastic member 722, a blocking rod 723, and a second elastic member 724 that are relatively disposed.

[0056] Among them, the two clamping plates 721 are both rotatably arranged on the circular cylinder 300, and the two clamping plates 721 are both located in the second accommodating cavity 330, and a wedge-shaped edge 7211 is provided at one end of the clamping plate 721 close to the second opening 340, and a clamping groove 7212 matching the clamping block 711 is provided on the outer wall of the clamping plate 721 close to the wedge-shaped edge 7211. The two ends of the first elastic member 722 are respectively connected to the two clamping plates 721, and the first elastic member 722 is located between the two clamping plates 721. The two blocking rods 723 are slidably arranged on the circular cylinder 300, and optionally, an axial hole (not shown in the drawings) can be provided on the circular cylinder 300, and the middle part of the blocking rod 723 is penetrated into the axial hole. At the same time, one end of the two blocking rods 723 extends into the first accommodating cavity 310, and the other end of the two blocking rods 723 extends into the second accommodating cavity 330. The parts of the two blocking rods 723 located in the second accommodating cavity 330 are connected to one end of the clamping plate 721 near the second opening 340. The second elastic member 724 is arranged between the circular cylinder 300 and the blocking rod 723, and the second elastic member 724 is connected to the blocking rod 723, so that the second elastic member 724 can change the state during the sliding process of the blocking rod 723. Optionally, the first elastic member 722 and the second elastic member 724 can both be elastic members such as springs and shrapnel. For example, when a spring is selected, the spring is arranged between the circular cylinder 300 and the blocking rod 723, and the spring is sleeved on the sliding rod of the blocking rod 723.

[0057] In the present embodiment, when the first hook 210 does not push the two blocking rods 723, the two blocking rods 723 extending into the first accommodating cavity 310 are in contact with each other. At this time, the first elastic member 722 and the second elastic member 724 are both in a natural state, and the clamping block 711 is engaged in the clamping groove 7212, so that the third hook head 710 is completely in the second accommodating cavity 330. When the first hook 210 pushes the two blocking rods 723, the two blocking rods 723 extending into the first accommodating cavity 310 receive the pushing force and abut against each other. Separate, at this time, the blocking rod 723 pushes the two card plates 721 to rotate, and the driving force makes the parts of the card plates 721 close to the wedge edges 7211 approach each other, the first elastic member 722 is compressed, the second elastic member 724 is stretched, and the parts of the card plates 721 away from the blocking rod 723 move away from each other. At this time, the card block 711 is disengaged from the card slot 7212, and under the action of gravity, the third hook head 710 slides in the second accommodating cavity 330 and moves away from the card plate 721, so that the third hook head 710 moves out of the second accommodating cavity 330. When the first hook 210 gradually moves away from the blocking rod 723, the parts of the two blocking rods 723 extending into the first accommodating cavity 310 are again abutted against each other, and the first elastic member 722 and the second elastic member 724 are transformed into a natural state. At this time, the end of the third hook head 710 close to the second accommodating cavity 330 is blocked by the wedge-shaped edge 7211, thereby keeping the position fixed. When a force is applied to the third hook head 710 from the outside, the third hook head 710 moves into the second accommodating cavity 330 and squeezes the wedge-shaped edge 7211 at the same time. 1, the extrusion force pushes the two clamping plates 721 to rotate, so that the parts of the clamping plates 721 close to the wedge-shaped edge 7211 are close to each other, the first elastic member 722 is compressed, and the second elastic member 724 is stretched, until the clamping block 711 moves to the clamping groove 7212. At this time, under the action of the first elastic member 722 and the second elastic member 724, the two clamping plates 721 rotate in the opposite direction until the clamping block 711 is engaged in the clamping groove 7212, and at the same time, the parts of the two blocking rods 723 extending into the first accommodating cavity 310 are again abutted against each other.

[0058] In some optional embodiments, such as Figure 4 As shown, the clamping plate assembly 640 includes a clamping plate 641 and a third elastic member 642. The clamping plate 641 is parallel to the discharge direction of the discharge end 420 so as to better clamp the circular cylinder 300. The two ends of the third elastic member 642 are respectively fixed on the surrounding plate 610 and the clamping plate 641. When the two clamping plates 641 do not clamp the circular cylinder 300, the third elastic member 642 is in a natural state. When the two clamping plates 641 clamp the circular cylinder 300, the third elastic member 642 is in a compressed state under the extrusion of the circular cylinder 300, so that the circular cylinder 300 is always tightly clamped between the two clamping plates 641. Optionally, the third elastic member 642 can be an elastic member such as a spring or a shrapnel.

[0059] Furthermore, in order to enable the two clamping plates 641 to smoothly approach and move away from each other, and to prevent the clamping plates 641 from swinging during movement, causing the clamping plates 641 to be non-parallel to the discharge direction of the discharge end 420, thereby hindering the rotation of the circular cylinder 300, the clamping plates 641 are slidably arranged on the enclosure 610. Optionally, a slide groove (not shown in the drawings) can be arranged on the inner side wall of the enclosure 610, and the clamping plates 641 are limited in the slide groove and can move in the slide groove.

[0060] In some optional embodiments, such as Figure 7 As shown, the opening and closing mechanism 630 includes clamping arms 631 arranged opposite to each other and fourth elastic members 632 arranged opposite to each other. The two clamping arms 631 are both rotatably arranged on the circular cylinder 300, and the rotation axes of the two clamping arms 631 coincide with each other. One end of the two fourth elastic members 632 is fixed on the circular cylinder 300, and the other ends of the two fourth elastic members 632 are respectively fixed on the two clamping arms 631. When the two clamping arms 631 are closed, a clamping area is formed in the middle of the two clamping arms 631, and the clamping area matches the outer dimensions of the first rotating shaft 620. At this time, the fourth elastic member 632 is in a stretched state; when the two clamping arms 631 are opened and closed, the two clamping arms 631 form an avoidance space matching the width of the first rotating shaft 620. At this time, the fourth elastic member 632 is still in a stretched state, but the stretching degree of the fourth elastic member 632 is reduced. When the force applied by the first driving mechanism to the circular cylinder 300 is greater than the tensile force of the fourth elastic member 632 when the two clamping arms 631 are opened and closed, the first rotating shaft 620 pushes the two clamping arms 631 apart, so that the two clamping arms 631 are opened and closed, so that the first rotating shaft 620 can be moved out of the card interface 350 through the sliding groove 360, and then the circular cylinder 300 can be detached from the first rotating shaft 620. Optionally, the fourth elastic member 632 can be an elastic member such as a spring or a spring sheet.

[0061] It should be noted that, in order to facilitate the transmission of the circular cylinder 300 , the clamping arm 631 and the fourth elastic member 632 are both arranged inside the circular cylinder 300 . Optionally, a movable space can be set on the side wall of the circular cylinder 300 to accommodate the clamping arm 631 and the fourth elastic member 632 .

[0062] In order to avoid the situation that the third elastic member 642 fails or the third elastic member 642 is axially deformed, the clamping plate 641 is deflected and the rotation of the circular cylinder 300 is affected. Figure 5 As shown, an auxiliary push-pull structure 800 is further provided between the clamping plate 641 and the first rotating shaft 620 . The auxiliary push-pull structure 800 is used to drive the two groups of clamping plates 641 to approach each other when the circular cylinder 300 rotates relative to the surrounding plate 610 .

[0063] Specifically, the auxiliary push-pull structure 800 includes mutually meshing gears 810, a torsion spring 820, and rows of teeth 830 arranged in parallel with each other. The first rotating shaft 620 is sleeved on one of the gears 810, and the torsion spring 820 is arranged between one of the gears 810 and the first rotating shaft 620. When the first rotating shaft 620 rotates relative to the enclosure 610, the torsion spring 820 provides a blocking force to prevent the first rotating shaft 620 from rotating. Both rows of teeth 830 are slidably arranged on the enclosure 610, and the two rows of teeth 830 are respectively arranged on both sides of two gears 810 arranged side by side, and the two rows of teeth 830 are respectively meshed and connected with the two gears 810, and the two rows of teeth 830 are also respectively connected to the two clamping plates 641.

[0064] In this embodiment, when the circular cylinder 300 is dragged by the first mounting portion and changes from a vertical state to an inclined state, the circular cylinder 300 drives the first rotating shaft 620 to rotate on the enclosure 610, and the gear 810 connected to the first rotating shaft 620 also rotates, thereby driving another gear 810 to rotate synchronously, so that the two gears 810 can respectively drive the two rows of teeth 830 to slide on the enclosure 610, thereby driving the two clamping plates 641 to move, so that the two clamping plates 641 are away from each other, and when the sling 200 is pulled out of the first accommodating cavity 310, under the action of gravity, the first rotating shaft 620 rotates on the enclosure 610, and the gear 810 drives the two rows of teeth 830 to slide on the enclosure 610, thereby driving the two clamping plates 641 to move, so that the two clamping plates 641 are away from each other. Under the joint action of the first and second elastic members 642, the splints 641 approach each other, and the gear 810 connected to the first rotating shaft 620 rotates in the opposite direction, thereby driving the other gear 810 to rotate synchronously. In this way, the two gears 810 can respectively drive the two rows of teeth 830 to slide on the enclosure 610, so that the two splints 641 approach each other until the circular cylinder 300 is changed from an inclined state to a vertical state. In addition, during the movement of the splint 641, the row of teeth 830 slides along a fixed path to play a certain limiting role, thereby preventing the splint 641 from deflecting.

[0065] In some optional embodiments, such as Figure 1 , Figure 2As shown, the bottom of the transport trough 400 is provided with an avoidance groove 440, and the pushing mechanism 500 includes a push head 510, a telescopic mechanism 520, and a lifting mechanism 530. The telescopic mechanism 520 is connected to the push head 510 in a transmission manner. When the telescopic mechanism 520 is in an extended state, the telescopic mechanism 520 drives the push head 510 to move horizontally along the extension direction of the avoidance groove 440. The lifting mechanism 530 is connected to the telescopic mechanism 520. When the lifting mechanism 530 is in a working state, the lifting mechanism 530 drives the telescopic mechanism 520 to approach the transport trough 400 until the push head 510 is inserted into the avoidance groove 440, and part of the push head 510 extends into the transport trough 400, so that when the telescopic mechanism 520 drives the push head 510 to move, the push head 510 can push the circular cylinder 300 in the transport trough 400 to move. When the pushing head 510 is pushed to the discharge end 420, the lifting mechanism 530 drives the telescopic mechanism 520 to move away from the transport trough 400 until the pushing head 510 is moved out of the avoidance groove 440, and then the telescopic mechanism 520 drives the pushing head 510 to move to the vicinity of the feeding end 410. Finally, the lifting mechanism 530 drives the telescopic mechanism 520 to approach the transport trough 400 until the pushing head 510 is inserted into the avoidance groove 440, and part of the pushing head 510 extends into the transport trough 400. In this way, the telescopic mechanism 520 continues to push the pushing head 510 to move, and continues to push the circular cylinder 300 in the transport trough 400 to move.

[0066] In this embodiment, the cooperation of the lifting mechanism 530, the avoidance groove 440 and the telescopic mechanism 520 prevents the circular cylinder 300 placed in the transport groove 400 from blocking the push head 510 from moving back to the feed end 410. It should be noted that the telescopic mechanism 520 and the lifting mechanism 530 are prior art, and their specific structures are not described here. For example, the telescopic mechanism 520 uses an electric push cylinder, and the lifting mechanism 530 uses a linear motor.

[0067] In some optional embodiments, such as Fig. 9 As shown, the transport line 100 includes a track 110 , an endless drag chain 120 , and a swing damping mechanism 130 .

[0068] Specifically, the circulating drag chain 120 is disposed on the track 110 , and the swing damping mechanism 130 is disposed on the circulating drag chain 120 . The swing damping mechanism 130 is used to mount the sling 200 , so that the swing damping mechanism 130 moves together with the circulating drag chain 120 .

[0069] The swing damping mechanism 130 includes a first mount 131, a second shaft 132, a second mount 133, a first friction plate 134, a second friction plate 135, and an anti-drop hook 136. The first mount 131 is fixed on the circulating drag chain 120, the second shaft 132 is rotatably mounted on the first mount 131, and the second mount 133 is sleeved on the second shaft 132, so that the second mount 133 can rotate relative to the first mount 131. The first friction plate 134 is rotated. The lower end is rotatably arranged on the second rotating shaft 132, the upper end of the first friction plate 134 is fixed on the first hanging seat 131, and the upper end of the second friction plate 135 is sleeved on the second rotating shaft 132, so that the second friction plate 135 can rotate with the second rotating shaft 132, the second friction plate 135 and the first friction plate 134 are close together, the lower end of the second friction plate 135 is fixed on the second hanging seat 133, and the anti-detachment hook 136 is fixed on the second hanging seat 133.

[0070] In this embodiment, the second friction plate 135 and the first friction plate 134 interact with each other to increase the resistance of the second mount 133 when rotating relative to the first mount 131, and the sling 200 hung on the anti-slip hook 136 shakes greatly after being pulled out of the first accommodating chamber 310, which can avoid colliding with other equipment or operators in the working space. In addition, the sling 200 hung on the anti-slip hook 136 can also be quickly transformed into a vertical state under the action of gravity, which is convenient for the subsequent hanging of the object to be sprayed on the sling 200.

[0071] In order to realize automatic loading, reduce the number of personnel, and improve the working efficiency, in some optional embodiments, such as Fig.10 , Fig.11 As shown, the automatic loading device of the automatic paint spraying line hanger also includes an automatic loading mechanism 900, and the automatic loading mechanism 900 includes a material trough 910, a sliding rod 920, a push rod 930, a second driving mechanism 940, and a mechanical arm 950.

[0072] Among them, the material trough 910 is provided with a discharge channel 911, the discharge channel 911 is provided with an inclined section 9111 and a straight section 9112, the straight section 911 has a clamping groove 9113, and the sliding rod 920 is provided on the material trough 910, and the sliding rod 920 matches the extension path of the inclined section 9111 and the straight section 9112. When the circular cylinder 300 is inserted into the inclined section 9111 of the material trough 910, the second hook head 220 is hung on the sliding rod 920, so that it can be ensured that when the circular cylinder 300 moves to the clamping groove 9113 in the inclined section 9111 and the straight section 9112 in turn, the hook surface of the second hook head 220 on the circular cylinder 300 is always facing upward. The push rod 930 is provided with a push head 931, and the push head 931 is provided with a limit groove 9311 that matches the height of the second hook head 220. When the circular cylinder 300 slides into the clamping groove 9113, the second hook head 220 with the hook surface facing upward is limited in the limit groove 9311. Then, the second driving mechanism 940 pushes the push rod 930 to move back and forth along the clamping groove 9113 to complete the transfer operation of a circular cylinder 300. Since the second hook head 220 is limited in the limit groove 9311, when the push rod 930 pushes the circular cylinder 300 to move in the clamping groove 9113, the hook surface of the second hook head 220 always faces upward. Finally, the robot arm 950 transforms the circular cylinder 300 from a horizontal state to a vertical state and places it at the feed end 410. By repeating the above operations, multiple circular cylinders 300 can be loaded in the transport trough 400.
