Description

Liquid supply device for soft capsule molding machine.

[0001] The present invention relates to a liquid supply device for a soft capsule molding machine, and more specifically, to a liquid supply device for a soft capsule molding machine that enables a linear device to operate stably even when liquid overflows, and is also easy to maintain and manage.

[0002] In general, a soft capsule molding machine is a device for manufacturing capsules containing a liquid inside, and in particular, spreader boxes are provided symmetrically on the left and right sides, and the spreader boxes receive liquid gelatin and widely spread it over a casting drum that rotates at a low speed, and the casting drum cools the liquid gelatin to form a sheet, and at the same time, the sheet is supplied to a capsule molding machine in a tightly spread state through a guide roller, and the capsule molding machine combines a pair of gelatin sheets into one through a pair of die rolls that form pockets, and when a liquid is injected between them, the edges are cut to encapsulate.

[0003] Here, the chemical liquid is injected at a constant rate through a chemical liquid supply device according to the timing when the pockets of a pair of die rolls are aligned, and in particular, the chemical liquid supply device includes a storage tank that temporarily stores the chemical liquid in order to repeatedly inject a fixed amount of the chemical liquid, a chemical liquid supply block that is connected to the storage tank to receive the chemical liquid and to constantly supply the chemical liquid to a wedge, a plurality of pistons mounted on both left and right sides of the chemical liquid supply block to push out or fill the chemical liquid present in the path when stroking, a slide block that repeatedly strokes the plurality of pistons mounted on both left and right sides of the supply block, and a linear device that repeatedly moves the slide block in a straight line back and forth.

[0004] However, since the conventional slide block is equipped with a linear device at the bottom center to move the slide block back and forth evenly left and right, there was a problem that when the chemical liquid in the storage tank overflows or leaks out, the linear device located directly below is contaminated.

[0005] That is, since the medicinal solution is composed of various ingredients and is often viscous or contains granules, etc., when the medicinal solution is supplied, it may suddenly overflow due to density / pressure differences caused by viscosity or granules, or when replacing with a new size or new drug, the medicinal solution may suddenly overflow and leak out due to changes in setting conditions or errors in operation by the administrator.

[0006] However, in this case, if the viscous liquid or granules contaminate the motor of the linear device located at the bottom of the slide block, the viscous liquid may harden, causing the motor to be overloaded, or the linear device may move irregularly, causing the liquid injected into the capsule to be defective due to insufficient content.

[0007] Therefore, whenever the existing medicine overflowed or a new medicine / size was to be replaced / adjusted, the storage tank, supply block, and slide block located at the top had to be sequentially separated one by one, and only then the linear device located at the bottom and its surroundings had to be thoroughly cleaned and dried before being used again. In other words, the structure was difficult to maintain and manage.

[0008] Therefore, the problem to be solved by the present invention is to provide a drug supply device for a soft capsule molding machine that minimizes contamination of the surroundings even when the drug overflows, while allowing a linear device to continuously and stably inject a fixed amount of drug, and is easy to maintain and manage.

[0009] Accordingly, the present invention relates to a drug supply device for a soft capsule molding machine, comprising a slide block for repeatedly moving a piston mounted in a chamber of a drug supply block to repeatedly inject a fixed amount of drug during capsule molding, and a linear device for repeatedly moving the piston in a straight line at regular intervals.

[0010] The slide block edge of the above-mentioned liquid supply device forms an isolation room by connecting multiple partition walls at a certain distance above the base plate to prevent overflowed liquid from leaking out.

[0011] A linear motion bush (LM BUSH) is formed in the above bulkhead,

[0012] The above linear motion bush (LM BUSH) is equipped with a linear motion shaft (LM SHAFT), and the linear motion shaft (LM SHAFT) is connected to a slide block at one end centered on the bulkhead, and the other end exposed outside the isolation room is connected to a fixed stand that is maintained horizontally with the slide block.

[0013] The above fixed member is connected to the moving table of the linear device that moves back and forth in a straight line outside the isolation room,

[0014] Even if the liquid overflows, it is blocked by the isolation room, and at the same time, the slide block located inside the isolation room is equipped to move back and forth by the linear device located outside.

[0015] Accordingly, the present invention minimizes contamination of the surroundings while containing the drug solution in an isolation room even when the drug solution overflows, and in particular, enables continuous injection of a fixed amount of drug solution while stably moving the slide block by a linear device located laterally.

[0016] In addition, the present invention facilitates maintenance and management by allowing only the linear device located on one side to be easily removed / installed separately without disassembling the liquid supply block and the slide block.

[0017] In addition, the liquid supply block of the present invention operates in a state separated from the linear device, thereby minimizing the transmission of vibration or shock generated during the operation of the linear device, thereby enabling more stable and accurate liquid injection.

[0025] Accordingly, the present invention relates to a drug supply device for a soft capsule molding machine, comprising a slide block for repeatedly moving a piston mounted in a chamber of a drug supply block to repeatedly inject a fixed amount of drug during capsule molding, and a linear device for repeatedly moving the piston in a straight line at regular intervals.

[0026] The slide block edge of the above-mentioned liquid supply device forms an isolation room by connecting multiple partition walls at a certain distance above the base plate to prevent overflowed liquid from leaking out.

[0027] A linear motion bush (LM BUSH) is formed in the above bulkhead,

[0028] The above linear motion bush (LM BUSH) is equipped with a linear motion shaft (LM SHAFT), and the linear motion shaft (LM SHAFT) is connected to a slide block at one end centered on the bulkhead, and the other end exposed outside the isolation room is connected to a fixed stand that is maintained horizontally with the slide block.

[0029] The above fixed member is connected to the moving table of the linear device that moves back and forth in a straight line outside the isolation room,

[0030] Even if the liquid overflows, it is blocked by the isolation room, and the slide block located inside the isolation room is equipped to be moved by the linear device located outside.

[0031] The following is a detailed description of the present invention with reference to the attached drawings.

[0032] Figures 1 and 2 show the overall appearance of a soft capsule forming machine according to an embodiment of the present invention.

[0033] With reference to this, the gelatin soft capsule forming machine (1) according to an embodiment of the present invention is

[0034] A pair of spreader boxes (10) are provided symmetrically on the left and right sides, a casting drum (20) that rotates at a low speed is provided at the bottom of each spreader box (10), and a molding machine (40) is provided around each casting drum (20) together with a guide roller (30), so that the liquid gelatin spread by the spreader box (10) is solidified by the casting drum (20) into a sheet, and at the same time, the guide roller (30) supplies the solidified gelatin sheet to the molding machine (40) in a tightly spread state.

[0035] At this time, the molding machine (40) is configured to include a pair of die rolls that form pockets in the shape of dividing the capsule in half, and when a pair of gelatin sheets are joined by the respective die rolls (41) so that the pockets match, a wedge (42) connected to the liquid supply device (100) located at the top injects the liquid and cuts the edge to encapsulate.

[0036] FIG. 3 shows the overall appearance of a liquid supply device according to an embodiment of the present invention, FIG. 4 is an exploded perspective view showing the configuration of a liquid supply device according to an embodiment of the present invention, and FIG. 5 shows a linear device according to an embodiment of the present invention.

[0037] With reference to this, the liquid supply device (100) connected to the wedge (42) repeatedly supplies a fixed amount of liquid according to the timing when the pockets of one die roll and the other die roll match, according to the instructions of the controller.

[0038] At this time, the chemical supply device (100) includes a chemical supply block (120) having a compartment (124) and a flow conversion module (130) inside to supply a fixed amount of chemical to the wedge (42) at the bottom of the storage tank (110) while having a storage tank (110) for temporarily storing chemical supplied from the outside.

[0039] In particular, the left and right compartments of the above-mentioned liquid supply block (120) are provided with a plurality of pistons (140) for pushing the filled liquid to the wedge (42), and each piston (140) moves back and forth to one side or the other by the slide block (150) to supply the liquid present in each compartment or path to the wedge.

[0040] Here, the slide block (150) is provided so as to be able to slide left and right on a flat metal base plate (165), and in particular, a plurality of partition walls (161) are combined on the edge of the base plate (165) with the slide block (150) as the center, thereby forming an isolation room (160) for blocking and receiving the overflowed liquid inside.

[0041] In addition, a cover body that surrounds a liquid supply block (120) or a storage tank (110) according to an embodiment can be formed on the upper part of the isolation room (160), and the cover body is provided so as to be able to be opened and closed.

[0042] In addition, a linear motion bush (hereinafter referred to as LM BUSH) (162) formed in a left or right partition (161) forming the isolation room (160) is formed in a manner such that the linear motion bush (hereinafter referred to as LM BUSH) is perforated left and right in accordance with the movement direction of the slide block (150), and a linear motion shaft (hereinafter referred to as LM SHAFT) (163) is provided in the LM BUSH (162), and one end of the LM SHAFT (163) is directly / indirectly connected to a slide block (150) that can slide left and right, and the other end of the LM SHAFT (163) is provided so as to always protrude outside the isolation room (160).

[0043] At this time, the LM SHAFT (163) and LM BUSH (162) protruding outside the isolation room (160) are formed in multiple numbers, so that when the linear device operates, multiple LM SHAFTs (163) move simultaneously to prevent the left and right of the slide block (150) from deviating and to move horizontally as consistently as possible.

[0044] In addition, the other end of the LM SHAFT (163) protruding outside the isolation room (160) is connected to a fixed member (164) that is maintained horizontally with the bulkhead (161), and the fixed member (164) is vertically assembled to a moving table (171) of a linear device (170) that moves back and forth in a straight line.

[0045] In addition, the linear device (170) is provided with a linear motor (172) composed of a mover and a stator at the bottom of a moving table (171) for linear reciprocating movement, and guide rails (173) are formed on both left and right sides on a bed (175) that fixes the stator, and a slider (174) is mounted on each guide rail (173) so as to be able to move in the front and rear directions, and each slider (174) is fixedly installed at the bottom of the moving table (171), so that when the linear motor (172) operates, the moving table (171) repeatedly makes linear reciprocating movements, and moves the slide block (150) and piston (140) connected to one end of the LM SHAFT (163) through the fixing member (164) that is fixed vertically to the moving table (171), thereby enabling the filling or discharging of the drug solution into the compartment.

[0046] Accordingly, the present invention is to minimize contamination of the surroundings while the chemical solution contained in the storage tank (110) is contained in the isolation room (160) even when the chemical solution overflows due to an operator's error, density difference, pressure difference, etc., and to enable repeated injection of a fixed amount of chemical solution by continuously and stably moving the slide block (150) by the linear device (170) located laterally.

[0047] In addition, the linear device (170) of the present invention forms a linear scale (181) at the left or right end of the moving table (171), and an encoder (180) is installed around the corresponding guide rail (173), so that when the moving table (171) moves, its position can be confirmed and the distance of linear reciprocating movement can be controlled.

[0048] At this time, a sensor block (183) is installed around the guide rail (173) on which the encoder (180) is installed to constantly determine the starting point (reference point) when the moving table (171) moves, and according to an embodiment, a limiter (184) is installed around the slider (174) moving along the guide rail (173) to limit the slider (174) to move constantly within a specified range.

[0049] In addition, a moving handle (176) is formed in a direction perpendicular to the moving direction of the moving table (171) on the bed (175) of the linear device (170), and a moving wheel (177) protruding downward is formed around the moving handle (176), so that when the fixed base (164) is separated, the moving handle (176) is pushed and pulled to move over the lower plate of the liquid supply device and can be easily removed / installed.

[0050] Accordingly, the present invention facilitates maintenance and management by allowing only the linear device (170) located on one side to be separately removed or mounted without disassembling the storage tank (110), the liquid supply block (120), the slide block (150), and the piston (140).

[0051] In addition, the isolation room (160) may be installed in close contact with the linear device at the same height, but preferably, a support (166) is formed at the bottom of the base plate (165) of the isolation room (160) so that the linear device (170) and the isolation room (160) are spaced apart from each other at different heights, thereby reducing the shock transmission and vibration generated when the moving table (171) of the linear device (170) reciprocates linearly, thereby enabling more stable and accurate injection of the drug.

[0052] In addition, the storage tank (110) temporarily stores the chemical solution supplied from an external chemical solution tank and supplies it to the chemical solution supply block (120), and depending on the embodiment, it further includes a heating / cooling means to stably supply the chemical solution without it being spoiled.

[0053] In addition, the liquid supply block (120) forms a plurality of channels (121) in the vertical direction on the left and right sides with the center as the center, and a compartment (124) is formed at the end of each channel (121), and a piston (140) is mounted in each compartment (124).

[0054] At this time, the flow path (121) is formed with a supply flow path (122) on one side and the other side of the lower part for filling the chemical liquid of the storage tank (110) into the compartment, and a discharge flow path (123) on one side and the other side of the upper part for discharging the chemical liquid of the compartment out of the outlet. In addition, a flow path conversion module (130) is provided between the supply flow path (122) and the discharge flow path (123), and a conversion flow path (131) is formed in the flow path conversion module (130) for connecting the supply flow path (122) or the discharge flow path (123) so as to enable conversion of the flow paths.

[0055] Here, the euro conversion module (130) has a rectangular body (132) formed long in the horizontal direction, and has a conversion path formed in accordance with the supply path or the discharge path of the liquid supply block, and the conversion path (131) is formed in the left and right directions as a first conversion path (131a) connecting the supply path and the discharge path and a second conversion path (131b) connecting the storage tank (110) and the supply path, and is alternately formed in a vertical direction in accordance with the stroking distance of the body (132).

[0056] In addition, the body (132) is provided so as to be able to perform a linear reciprocating motion repeatedly at regular intervals, and when the body (132) moves from one side to the other side or vice versa, when it moves from the other side to one side, it is provided so as to be able to switch the flow path by being connected to the supply flow path (122) or the discharge flow path (123) through the switching flow path (131).

[0057] In addition, the piston (140) is mounted in the compartments (124) on the left and right sides of the liquid supply block (120), and the liquid is filled in the compartment (124) when the piston (140) is pulled in accordance with the opening time when the supply path and the storage tank are connected, or conversely, the liquid in the compartment (124) is discharged out of the discharge port when the piston (140) is pushed in accordance with the opening time when the supply path and the discharge path are connected.

[0058] At this time, it is preferable that the piston (140) be arranged in a shape in which multiple pistons mounted on the left and right compartments face each other with a certain interval between them, and depending on the embodiment, the pistons on the left and right may form layers in the vertical direction.

[0059] In addition, the slide block (150) is provided so as to be able to slide left and right on a flat metal base plate (165), and in particular, the pistons (130) mounted on the left and right compartments of the chemical supply block (120) are arranged so as to face each other. Therefore, when the slide block (150) moves in one direction, one piston is pulled to charge the chemical, and at the same time, the other piston is pushed to discharge the chemical. In addition, when the slide block (150) moves in the other direction, conversely, one piston is pushed to discharge the chemical, and the other piston is pulled to charge the chemical, so that each piston is configured to be able to continuously charge and discharge the chemical, thereby minimizing the time lost.

[0060] Figures 6 to 8 are operating diagrams showing the process of filling or discharging a liquid into one or the other compartment while the flow is switched when the slide block is moved to one or the other side by the linear device.

[0061] Referring to this, when the linear motor (172) of the present invention applies current to the coil, a magnetic field is generated along the coil, thereby generating a driving force to one side, and accordingly, the slider (174) moves to one side along the guide rail (173), thereby moving the moving table (171) to one side.

[0062] At this time, the fixed member (164) assembled on the above-mentioned moving table (171) pressurizes the LM SHAFT (163) to move the slide block (150) located inside the isolation room (160) to one side, thereby pulling the piston (140a) on one side around the liquid supply block (120) and pushing the piston (140b) on the other side.

[0063] In addition, in one compartment (124a) equipped with one piston (140a), the chemical liquid in the storage tank (110) flows down along one supply path (122a) and is filled in one compartment (124a), and at the same time, in the other compartment (124b), the chemical liquid is pushed out by the other piston (140b) and moves out of the discharge port through the other discharge path (123b), enabling discharge of a fixed amount of chemical liquid.

[0064] And then, when the body (132) of the euro conversion module (130) moves from one side to the other side, the first conversion path (131a) formed alternately on one side and the other side connects the one-side supply path (122a) and the one-side discharge path (123a) to each other, and at the same time, the other-side supply path (122b) and the storage tank (110) are connected by the second conversion path (131b) located on the other side.

[0065] And then, when the linear motor (172) supplies current to the coil in the opposite direction, a magnetic field is generated in the opposite direction along the coil, and a driving force is generated to the other side, causing the slider (174) to move to the other side along the guide rail (173), thereby moving the moving table (171) to the other side.

[0066] At this time, the fixed member (164) assembled to the above moving table (171) pulls the LM SHAFT (163) to move the slide block (150) located inside the isolation room (160) to the other side, thereby pushing one piston (140a) around the liquid supply block (120) and pulling the other piston (140b).

[0067] At this time, the medicine filled in one compartment (124a) is pushed out by one piston (140a) and moves out of the discharge port along one discharge path (123a), so that the medicine filled in the one compartment (124a) can be discharged in a fixed amount, and the medicine in the other compartment (124b) moves down along the other supply path (122b) and is filled in the compartment (124b), so that the slide block (150) can simultaneously fill and discharge the medicine with just one movement.

[0068] Accordingly, the present invention minimizes contamination of the surroundings while containing the chemical liquid inside the isolation room (160) even when the chemical liquid overflows, and in particular, the linear device (170) located laterally moves the slide block (150) stably regardless of the overflowed chemical liquid to enable injection of a fixed amount of chemical liquid, and without disassembling the slide block (150) and the chemical liquid supply block (120), only the linear device (170) located on one side can be easily detached or installed separately, thereby facilitating maintenance and management.
