Description

[Technical field]

[0001] The present invention relates to an automated device for automatically transporting and depositing container bags. [Background technology]

[0002] A container bag is a type of packaging container that contains raw materials such as the electrode active material of a battery. These container bags are sometimes called flexible container bags, which are soft and deformable, and are also called flexcon bags for short.

[0003] Previously, workers manually added active material to all parts using a manual hoist. Specifically, previously, a manual hoist was used to transport the container bag, and the amount of active material added was adjusted while visually checking the discharge of the active material. If the discharge was not smooth due to clumping of the active material, the worker would hit it with a hammer to break up the clumps while continuing to discharge the material. Once discharge was complete, the tip of the discharge part was tied with a string to prevent the remaining amount from falling out.

[0004] Therefore, a control technique for a container bag for feeding active material into a hopper is required, as described below.

[0005] 1) Container bag transportation

[0006] 2) Tilt of container bags during transportation

[0007] 3) Automatic detection of the weight of the container bag and height correction of the container bag by discharging active material into the hopper (The length of the container bag increases as active material is discharged from the container bag, and the height must be increased by the increased length)

[0008] 4) The need to eliminate clumping of active material in the container bag when discharging is interrupted

[0009] 5) After the active material in the container bag has been discharged, the discharge of the minute amount of active material remaining in the discharge port is blocked (to prevent the remaining amount from falling onto the floor). Summary of the Invention [Problem to be solved by the invention]

[0010] SUMMARY OF THE PRESENT EMBODIMENT It is therefore an object of the present invention to provide an automated apparatus for automatically loading raw materials, such as active materials, into a hopper. [Means for solving the problem]

[0016] In the present invention, the hanger may further include load cells provided on both the left and right sides of the lower hanger.

[0017] In the present invention, the inclination of the container bag can be corrected by detecting the weight deviation of the load cells on both the left and right sides, and the height of the container bag can be adjusted in accordance with the change in weight of the load cells on both the left and right sides.

[0018] In the present invention, the hopper may include upper and lower photo-electric sensors that are vertically disposed near the inlet and detect the position of the end of the discharge portion of the container bag.

[0019] In the present invention, the hit post may include a support base provided on both sides of the hopper, and a striking plate extending inwardly from the upper end of the support base.

[0020] In the present invention, grippers are provided on both sides near the hopper's inlet, and each gripper includes a rod that can move back and forth horizontally inward, and is installed at different heights so that it can grip different parts of the container bag. Effect of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] The present invention will now be described in detail with reference to the accompanying drawings.

[0024] The present invention relates to an automated device for transporting and feeding container bags, and the container bag 10 is a big bag (Big Bag) for storing raw materials, and may be, for example, a flexible container bag (FIBC bag) that is soft and deformable. The upper part of the container bag 10 may have at least one or more sling bars 11 like a bag string, which can be hung on a hook 34 of a hanger 30, and the lower part of the container bag 10 may have an openable raw material discharge part 12. The container bag 10 may be composed of an outer packaging material and an inner packaging material. The raw materials are not particularly limited, and may be, for example, a mixer process active material, and more specifically, may be an active material (active material) of a battery electrode (negative electrode, positive electrode). The raw materials may be stored in the container bag 10 in the form of powder (powder) or particles.

[0025] Referring to FIG. 1 etc., the automated container bag transport and loading device according to the present invention may be composed of a rail 20, a hanger 30, a hopper 40, a hit post 50, a gripper 60 and the like.

[0026] Referring to FIG. 1, the rail 20 is for moving the hanger 30 and is arranged horizontally at a certain height (e.g., 3 to 10 m) to realize an overhead hoist transfer (OHT). The rail 20 can be fixed or supported by a suitable fixing or supporting means on a ceiling, a floor, or the like. The shape and size of the rail 20 are not particularly limited and can be set appropriately.

[0027] Referring to FIG. 1 etc., hanger 30 (also called carrier) is for moving container bags 10, is attached to rails 20 and can move back and forth horizontally along rails 20, and can also allow container bags 10 attached to the lower end to move back and forth vertically.

[0028] The horizontal and vertical reciprocating movements of the hanger 30 can be achieved by conventional mechanisms (pulleys and belts, gears and chains, cylinders and pistons, racks and pinions, reels and wires, etc.) that convert the rotational motion of a motor into linear motion, and an appropriate mechanism can be selected from among these as needed.

[0029] Referring to FIG. 2, the hanger 30 may be composed of an upper hanger 31, a lower hanger 32, a wire 33, a hook 34, a positioning hole 35, a positioning pin 36, a scissor frame 37, a load cell 38, and the like.

[0030] 2, the upper hanger 31 is attached to the lower part of the rail 20 and may be configured in a plate shape (a polygonal plate such as a square plate, a circular plate, an elliptical plate, etc.). The lower hanger 32 is disposed below the upper hanger 31 and may be configured in the same plate shape as the upper hanger 31.

[0031] 2, the wire 33 may be provided between the upper hanger 31 and the lower hanger 32 to connect them. An upper end of the wire 33 may be fixed to a roller or reel provided on the upper hanger 31 or the rail 20, and a lower end of the wire 33 may be fixed to the lower hanger 32. The wire 33 may be wound or unwound by the roller or reel, and the lower hanger 32 may be moved back and forth in the vertical direction.

[0032] Referring to Fig. 2 etc., the hook 34 is attached to the lower hanger 32 and configured in a ring shape to hang the container bag 10. Referring to Fig. 3 etc., the hook 34 is configured in at least one pair (preferably two or more pairs), and the pair of hooks may hold the string-like sling bar 11 of the container bag 10 at two points and have a spacing that minimizes the height of the container bag 10 and the sling bar 11 (applied to wide double hook). The hook 34 may be disposed at the lower end of the lower hanger 32, or may be disposed entirely within the range of the height (thickness) of the lower hanger 32.

[0033] Referring to FIG. 4, H1 is the height at which the rail 20 and the hanger 30 can be installed. Specifically, when the hook 34 is at the highest height, that is, when the lower hanger 32 rises and comes into close contact with the upper hanger 31, the height between the upper end of the rail 20 and the lower end of the hook 34 may be, for example, up to 1.2 m. H2 is the height of the container bag 10. Specifically, the height of the container bag 10 including the sling bar 11 hung on the hook 34 may be, for example, 1.8 m. H3 is the height of the manual work space. Specifically, the height of the manual work space between the lower end of the container bag 10 and the upper end of the hopper 40 may be, for example, 0.5 m. H4 is the height between the lower end of the hook 34 located at the highest height and the upper end of the hopper 40, for example, up to 2.3 m. As described above, the floor height may be insufficient, and therefore a solution to the insufficient floor height is required.

[0034] Referring to Fig. 5, in order to solve the problem of insufficient floor height in Fig. 4, the height of the container bag 10 can be minimized by maximizing the two-point gripping distance for each sling bar. Fig. 5(a) shows one-point gripping of the sling bar 11, Fig. 5(b) and Fig. 5(c) show two-point gripping of the sling bar 11, Fig. 5(b) is a front view of the container bag 10, and Fig. 5(c) is a side view of the container bag 10.

[0035] In FIG. 5, H5 is the height between the hook 34 and the upper end of the container bag 10 when gripped at one point, and this height is maximum when gripped at one point. That is, when gripping the sling bar 11 at one point, the sling bar 11 is hung from the hook 34 so that the height of the container bag 10 is increased by adding to the height of the sling bar 11. H6 is the height between the hook 34 and the upper end of the container bag 10 when gripped at two points, and it can be confirmed that this height can be minimized and is much smaller than H5 when gripping at two points. That is, when gripping the sling bar 11 at two points, the height of the container bag 10 decreases as the height of the sling bar 11 decreases. D1 is the gripping distance when gripped at two points, which is the distance (spacing) between a pair of hooks 34. By maximizing this gripping distance D1, the height of the container bag 10 can be minimized, and in this case, the upper end of the container bag 10 can be in close contact with the hook 34 or almost in close contact with it.

[0036] Also, the problem of insufficient floor height can be solved by making the traveling rail 20 and the hanger 30 compact. Specifically, when the upper hanger 31 and the lower hanger 32 are docked, the hook 34 is positioned at the highest height, and at this time, it is preferable that the height between the upper end of the rail 20 and the lower end of the hook 34 is designed to be a maximum of 1.2 m.

[0037] 3, a positioning hole 35 may be formed in one of the upper hanger 31 and the lower hanger 32, and a positioning pin 36 to be inserted into the positioning hole 35 may be formed in the other. In FIG. 3, the positioning hole 35 is formed in the upper hanger 31, and the positioning pin 36 is formed in the lower hanger 32, but the reverse is also possible. The positioning hole 35 may be formed in the lower surface of the upper hanger 31 in the form of a groove or hole, and the positioning pin 36 may be formed in the upper surface of the lower hanger 32 in the form of a protrusion.

[0038] 3, at least one pair of positioning holes 35 may be formed on both sides of the upper hanger 31, and at least one pair of positioning pins 36 may be formed on both sides of the lower hanger 32. The positioning holes 35 and the positioning pins 36 may have shapes and sizes corresponding to each other. As the container bag 10 moves upward along the lower hanger 32 and the hook 34, and the upper hanger 31 and the lower hanger 32 come into close contact with each other, the positioning holes 35 and the positioning pins 36 can dock.

[0039] When the container bag 10 moves left and right, a problem may occur in which the container bag 10 sways left and right. However, by docking the positioning hole 35 and the positioning pin 36, and by gripping the sling bar 11 at two points, the problem of the container bag 10 swaying left and right when the container bag 10 moves left and right can be solved or minimized.

[0040] 2 etc., the scissor frame 37 is provided between the upper hanger 31 and the lower hanger 32, and is extendable (deformable) in the vertical (height) direction. An upper end of the scissor frame 37 may be fixed to the upper hanger 31, and a lower end of the scissor frame 37 may be fixed to the lower hanger 32. When the container bag 10 is lowered, the height of the scissor frame 37 may be extended, and when the container bag 10 is raised, the height of the scissor frame 37 may be shortened. The scissor frame 37 may simply be passively extended and retracted by the active movement of the wire 33.

[0041] Although a problem of the container bag 10 swinging left and right may occur when the container bag 10 moves up and down, by applying a scissor frame 37 between the upper hanger 31 and the lower hanger 32, the problem of the container bag 10 swinging left and right when the container bag 10 moves up and down can be solved or minimized.

[0042] 6, the container bag 10 may tilt to one side when the active material is charged, and the length of the container bag 10 may increase when the active material is charged.

[0043] 7, in order to solve the problems of the inclination and increase in length of the container bag 10 in FIG. 6, load cells 38 may be installed on both the left and right sides of the lower hanger 32. At least one pair of the load cells 38 may be formed on both sides of the lower hanger 32, and the weight can be measured in real time. The inclination of the container bag 10 can be corrected by detecting the weight deviation of the load cells 38 on both the left and right sides, and the height of the container bag 10 can be adjusted according to the change in weight of the load cells 38 on both the left and right sides.

[0044] As shown in the left drawing of Fig. 7, when the container bag 10 is tilted downward to the right side, the load cell 38 detects the weight deviation and adjusts the displacement of the right wire 33, thereby correcting the tilt of the container bag 10 and aligning it. Also, as shown in the right drawing of Fig. 7, when the length of the container bag 10 increases, the load cell 38 detects the weight change and the wire 33 rises, thereby offsetting and correcting the increase in the length of the container bag 10.

[0045] 8, the hopper 40 is disposed under the rail 20, and raw materials inside the container bag 10 moved by the hanger 30 are inputted therein. When the height of the container bag 10 is adjusted, the discharge part 12 of the container bag 10 may come off the hopper 40, which may cause a problem of active material scattering. Therefore, when the height of the container bag 10 is adjusted, it is necessary to maintain the depth of the discharge part 12 of the container bag 10 entering the hopper 40.

[0046] 9, in order to solve the problem of active material scattering in FIG. 8, an upper photo sensor 41 and a lower photo sensor 42 are vertically installed near the inlet of the hopper 40 to detect the position of the end of the discharge part 12 of the container bag 10. At least one pair of upper photo sensors 41 are installed on both sides of the upper part of the inlet of the hopper 40 to detect the minimum (Min.) position of the end of the discharge part 12 of the container bag 10. At least one pair of lower photo sensors 42 are installed on both sides of the lower part of the inlet of the hopper 40 to detect the maximum (Max.) position of the end of the discharge part 12 of the container bag 10. Reflecting the detection results of both photo sensors 41 and 42, the container bag 10 can be lowered when the minimum (Min.) position is detected, and the container bag 10 can be raised when the maximum (Max.) position is detected.

[0047] Referring to FIG. 10, aggregation of the active material may occur near the discharge portion 12 of the container bag 10, causing the discharge to be interrupted.

[0048] 11, in order to solve the clumping problem of the active material in FIG. 10, a hit post 50 may be disposed near the inlet of the hopper 40. The hit post 50 may be of a fixed type, or may be composed of a support stand 51 provided on both sides of the hopper 40 and a striking plate 52 extending inward from the upper end of the support stand 51. As the hanger 30 reciprocates vertically, the container bag 10 is struck by the striking plate 52 of the hit post 50, thereby solving the clumping phenomenon of the active material.

[0049] Specifically, if there is no change in the weight of the load cell 38, it is determined that an agglomeration phenomenon of the active material has occurred, and the container bag 10 is repeatedly lowered and raised to collide with the striking plate 52 of the fixed hitting post 50, thereby eliminating the agglomeration of the active material. The load cell 38 can detect the moment when the container bag 10 is struck (collided) with the hitting post 50.

[0050] 12, conventionally, hopper custom input and finishing work were performed manually. Specifically, after a worker confirmed the input weight, he / she grasped the discharge part 12 of the container bag 10 and performed finishing. That is, conventionally, after the input of the raw materials was completed, a worker was required to input the container bag 10 for finishing work of the inner packaging material.

[0051] 13, in order to solve the problem of the manual work in FIG. 12, grippers 61, 62 can grip (finish) the discharge portion 12 of an empty container bag 10 that has completed the introduction of raw materials into the hopper 40, thereby blocking the discharge of the raw materials. The grippers 61, 62 are provided on both sides near the inlet of the hopper 40, and each of the grippers 61, 62 includes rods 63, 64 that can reciprocate horizontally inwardly, and can grip different portions of the container bag 10 due to different installation heights.

[0052] Referring to FIG. 13, the upper gripper 61 and the lower gripper 62 may be disposed under the striking plate 52 of the hitting post 50 and fixed to the support bases 51 on both sides, respectively. The upper gripper 61 and the lower gripper 62 may be disposed to face each other on the opposite sides, and the upper rod 63 and the lower rod 64 may move inward toward the center and approach each other at the center. The pressure of the grippers 61 and 62 may distort and deform the discharge section 12 to perform finishing, so that the remaining raw material does not fall to the floor. As shown in the figure, for effective finishing (sealing) of the discharge section 12, the lower end of the upper gripper 61 and the upper end of the lower gripper 62 may be disposed to be located at the same height. In this way, when the container bag 10 reaches a certain weight, the gripper 60 may block the discharge of the active material and perform finishing.

[0053] Referring to FIG. 14, the working space can be separated into a mixer room 80 and an antechamber 90 by a wall 70, but conventionally, separate rails 21, 22 were provided in the mixer room 80 and the antechamber 90, respectively, to operate the two spaces separately.

[0054] Referring to FIG. 15, in order to solve the separation problem of FIG. 14, a door is provided on the wall 70, and after the door is opened, the rail 22 of the front room 90 can be slid horizontally (arrow) to dock with the rail 21 of the mixer room 80, thereby allowing the container bag 10 and the hanger 30 to move freely between the mixer room 80 and the front room 90.

[0055] The process of feeding raw materials into the hopper will be described below in sequence with reference to Figures 16 to 23. Only one rail 20 may be provided, and multiple hangers 30, hoppers 40, hit posts 50, grippers 60, etc. may be provided. The container bag 10 may be placed on a stand.

[0056] Referring to FIG. 16, the hanger 30 is lowered, and the worker fixes the container bag 10 to the hanger 30, and after fixing, presses the work completion button (manual process).

[0057] Referring to FIG. 17, the hanger 30 is raised by the OHT, and after the container bag 10 is transported along the rail 20 to the designated position of the hopper 40, the hanger 30 is lowered (automatic process).

[0058] Referring to FIG. 18, an operator disassembles the lower portion of the container bag 10 and connects it to the inside of the hopper 40, and then presses a work completion button (manual process).

[0059] Referring to FIG. 19, the internal material of the container bag 10 is dumped into the hopper 40 by the OHT, and the weight is measured in real time by the load cell 38. If the internal material of the container bag 10 clumps together and there is no change in weight, the container bag 10 is raised and lowered to collide with a hit post 50 to break up the clumps (automatic process).

[0060] 20, the weight of the container bag 10 on the hanger 30 is measured in real time by the OHT using a load cell 38, and as the length of the container bag 10 increases due to the discharge of the internal material of the container bag 10, the internal material is poured into the inside of the hopper 40 while correcting the overall height of the container bag 10 (automatic process). When adjusting the overall height of the container bag 10, the end positions of the discharge part 12 are detected by photosensors 41 and 42 so that the end of the discharge part 12 does not come out of the hopper 40.

[0061] Referring to Figure 21, when the OHT completes material loading and the detected weight of the load cell 38 becomes 0, the gripper 60 bends the discharge section 12 of the container bag 10 to prevent any remaining fine material from escaping from the discharge section 12 (automatic process).

[0062] Referring to FIG. 22, the hanger 30 is raised by the OHT, and the empty container bag 10 that has completed loading is transported along the rail 20 to the recovery position, after which the hanger 30 is lowered (automatic process).

[0063] Referring to FIG. 23, an operator detaches and discards the empty container bag 10 that has been transported to the collection location (manual process).

[0064] That is, the work sequence is as follows: Lowering of the hanger (carrier) 30 → Transfer of the container bag 10 and lifting of the hanger 30 → Transporting the container bag 10 to the hopper 40 (horizontal movement along the rails 20) → Detection of weight deviation by the load cell 38 and alignment of the container bag 10 (correction of tilt, etc.) → Lowering of the container bag 10 and loading of the active material into the hopper 40 → Impact of the bottom of the container bag 10 by the hit post 50 to disintegrate the clumps → After loading of the set weight, discharge blocking by the gripper 60 (custom loading) → Lifting of the empty container bag 10 and moving to the collection position.

[0065] As described above, in the present invention, the container bag 10 can be automatically controlled by applying the OHT to feed the active material. Specifically, in the present invention, the container bag 10 is attached to the hanger 30 by applying the OHT with the rails 20 arranged at a certain height, and is automatically transported. The transported weight is measured in real time by the load cell 38 applied to the hanger 30. When the change in weight discharged due to the aggregation of the active material is negligible, the container bag 10 is moved up and down to collide with the hit post 50 to break up the aggregation. When the discharge to the hopper 40 is completed, the discharge part 12 is distorted and deformed by the gripper 60 so that the negligible remaining amount does not fall to the floor.
