Description

Heating device in the spreader box

[0001] The present invention relates to a spreader box of a soft capsule molding machine, and more specifically, to a heating device of a spreader box for keeping liquid gelatin provided in the inner space of the spreader box from solidifying.

[0002] Typically, a soft capsule molding machine is equipped with spreader boxes symmetrically on both the left and right sides, and the spreader boxes supply liquid gelatin onto a casting drum that rotates at a low speed. In addition, the casting drum rotates at a constant speed to cool the liquid gelatin and form a sheet, and a guide roller supplies the solidified gelatin sheet of the casting drum to a molding device in a taut, spread state. At this time, the molding device combines a pair of gelatin sheets pulled by the left and right guide rollers, and at the same time, when a liquid is injected between them, the edges are cut to encapsulate them.

[0003] Here, the spreader box supplies the mixed and stirred liquid gelatin from the storage tank and supplies it onto the low-speed rotating casting drum.

[0004] In particular, since the thickness of the gelatin sheet in the above-mentioned spreader box varies depending on the type and amount of the liquid, the amount of gelatin supplied upward to the casting drum is controlled by adjusting the opening width of the discharge port by changing the height of the blocking plate of the spreader box. At this time, a heating device is provided in the inner space of the spreader box to prevent the liquid gelatin contained within the inner space from solidifying when the liquid gelatin is supplied.

[0005] However, the internal space of the spreader box is limited, and especially when mixed and stirred liquid gelatin is supplied from the storage tank, high pressure exceeding the set pressure is generated due to various reasons such as air, viscosity, and density difference, so that the liquid gelatin is oversupplied, and the oversupplied gelatin overflows out of the spreader box and contaminates the surrounding area. And when the liquid gelatin overflows like this, the operation of the soft capsule molding machine must be stopped, and before the viscous liquid gelatin hardens, all the connecting components around the spreader box must be separated one by one, and the spreader box must be removed and washed separately.

[0006] In addition, even after production was completed, the spreader box had to be disassembled and cleaned for each lot, which was cumbersome because the heaters and sensors had to be removed and installed separately each time, and the connectors would break due to frequent removal and installation.

[0007] Therefore, the problem to be solved by the present invention is to provide a heating device for a spreader box in which the heating device is attached to the outside of the spreader box at an adjustable distance according to the position of the spreader box, and the spreader box can be easily removed or mounted.

[0008] In addition, the heating device of the present invention is intended to be a heating device that is completely sealed to the outside of a spreader box.

[0009] Therefore, the technical solution of the present invention is a heating device of a spreader box that supplies liquid gelatin from a storage tank and supplies it to a casting drum that rotates at a low speed.

[0010] A heating device is provided on the outer surface of the above spreader box,

[0011] The above heating device is provided so that the distance from the spreader box can be adjusted through a control means,

[0012] When the above heating device is placed in close contact with the outer surface of the spreader box, the liquid gelatin provided inside the inner space can be maintained without solidifying.

[0013] When the above heating device is pulled outward by the control means, a space is formed between the spreader box and the heating device, so that the spreader box can be easily mounted and removed through the space.

[0014] Accordingly, the present invention not only enables easy mounting and dismounting of only the spreader box regardless of the heating device, but also enables the heating device to be completely sealed without any gaps as the distance is adjusted according to the position of the spreader box, thereby maintaining the liquid gelatin provided in the inner space without hardening through heat transfer.

[0015] Figure 1 is a perspective view of a soft capsule forming machine according to an embodiment of the present invention.

[0016] Figure 2 is a front perspective view of a spreader box and a heating device according to an embodiment of the present invention.

[0017] Figure 3 is a rear perspective view of a spreader box and a heating device according to an embodiment of the present invention.

[0018] Figure 4 is a partially exploded perspective view of a heating device according to an embodiment of the present invention.

[0019] Figures 5 to 8 are operation status diagrams of a heating device according to an embodiment of the present invention.

[0020] The best form for carrying out the present invention is that the heating device is provided with a support portion that is long in the horizontal direction in accordance with the installation direction of the spreader box,

[0021] An assembly hole is formed in the center of the above support in the front-back direction,

[0022] An adjustment means is fastened to the assembly hole of the above support so as to be rotatable clockwise or counterclockwise, and the tip of the adjustment means protruding forward is connected to a heating part equipped with a heating wire.

[0023] The above control means rotates clockwise or counterclockwise so that the heating part is in close contact with the outer surface of the spreader box or forms a space apart from it.

[0024] Not only can the above spreader box be mounted and detached separately from the heating unit, but when the heating unit is in close contact with the outer surface of the spreader box, the liquid gelatin located in the inner space of the spreader box can be kept from hardening by heat transfer from the outside.

[0025] The following is a detailed description of the present invention with reference to the attached drawings.

[0026] Figure 1 is a perspective view showing the entire appearance of a soft capsule molding machine according to an embodiment of the present invention.

[0027] With reference to this, a soft capsule molding machine (1) according to an embodiment of the present invention is provided with spreader boxes (10) symmetrically on both left and right sides, the spreader boxes supply liquid gelatin from a storage tank and supply it onto a casting drum (20) that rotates at a low speed, the casting drum (20) cools the liquid gelatin to form a sheet, and the guide roller (30) supplies the cooled gelatin sheet to a molding device (40) in a taut and spread state, and the molding device (40) combines a pair of gelatin sheets supplied through respective guide rollers provided on both left and right sides, and at the same time cuts them into a capsule shape when a drug solution is injected into the inside thereof.

[0028] Figures 2 and 3 are front and rear perspective views showing the entire appearance of the spreader box.

[0029] With reference to this, the spreader box (10) of the present invention receives mixed and stirred liquid gelatin from a storage tank, buffers it in an internal space, and then simultaneously spreads it in a long horizontal direction onto a casting drum that rotates at a low speed.

[0030] At this time, the soft capsule molding machine (1) is equipped with a mechanism to control the amount or thickness of gelatin sprayed onto the casting drum according to the type and amount of the drug injected between the pair of gelatin sheets when the molding device (40) is combined, the size of the capsule, etc.

[0031] That is, the above spreader box (10) is provided with a blocking plate (11) in a box body that forms an inner space that is opened on one side, and the blocking plate is configured to be able to adjust the opening width of the discharge port while moving up and down by a driving device (not shown), thereby controlling the amount or thickness of gelatin to be sprayed onto a rotating casting drum.

[0032] And this spreader box (10) includes a horizontal maintenance device (11) and a heating device (12).

[0033] Here, the horizontal maintenance device (11) is provided to prevent the spreader box (10) from being pressed against the casting drum due to excessive pressure, and includes a bracket for mounting the spreader box (10), a mounting base for mounting the bracket, a shaft for enabling the bracket to be raised / lowered while mounted on the mounting base, and a spring for maintaining the spreader box in a pressed state while reducing the load applied to the casting drum.

[0034] In addition, the heating device (12) is provided to prevent the liquid gelatin provided in the inner space of the spreader box from hardening, and is particularly provided to be selectively and closely attached to the outside of the spreader box so that only the spreader box can be easily separated, while being provided so that the entirety is completely sealed according to the position of the installed spreader box, thereby keeping the liquid gelatin from hardening through heat transfer.

[0035] Figure 4 shows the configuration of a spreader box and a heating device equipped therewith according to an embodiment of the present invention.

[0036] With reference to this, a heating device (12) according to an embodiment of the present invention is provided on the outside of a spreader box (10), and the heating device (12) is provided with a heating unit (110) supported by an elastic body (120) that can move forward and backward so as to be in close contact with the outer surface of the spreader box (10) and, when the heating wire of the heating unit (110) operates, heat the outer surface of the close-contacted spreader box (10) to prevent the liquid gelatin provided inside the inner space from solidifying.

[0037] At this time, the heating unit (110) is pulled backward by the adjusting means (150) provided in the support unit (130), and a space is formed between the heating unit (110) and the spreader box (10), and the spreader box (10) in the space is provided so that it can be easily detached regardless of the heating device (12).

[0038] Here, the elastic body (120) is provided in multiple numbers on both sides at a constant distance from the control means (150) according to the embodiment, so that the heating part (110) is elastically supported and is constantly pressed forward, and at the same time, the heating part is completely pressed against the outer surface of the spreader box without any gaps, preventing it from being heated unevenly.

[0039] In addition, the above heating device (12) is configured in multiple ways according to the embodiment, and the multiple heating devices are provided in the front-back direction centered on the spreader box (10).

[0040] Preferably, a pair of heating devices (12) are provided on one side, one upper and one lower, with the spreader box as the center, and a heating device is provided on the other side at a position that is relatively lower than the upper heating device provided on one side and relatively higher than the lower heating device, so that the spreader box located in the middle can be pressurized from both sides to enable removal and installation.

[0041] In addition, the above support member (130) is fixed lengthwise in the horizontal direction in accordance with the direction in which the spreader box (10) is installed on the upper fixing member of the horizontal maintenance device (11) provided on both left and right sides centered on the spreader box (10).

[0042] At this time, the support member (130) is positioned at a certain distance from the spreader box (10), and an assembly hole (131) penetrating in the front-back direction is formed in the support member (130), while guide holes (132) are formed on both left and right sides centered on the assembly hole (131).

[0043] At this time, the control means (150) is rotatably fastened to the assembly hole (131) of the support member (130) in a clockwise or counterclockwise direction, and the heating member (110) that is elastically supported is pulled backward while protruding forward or retracting around the support member (130) according to the clockwise or counterclockwise rotation of the control means (150) so that the position (distance) can be adjusted.

[0044] And this control means (150) is provided with a body having a rotating handle on one side and a screw thread formed on the edge on the other side, and a stopper (151) having a catch frame is coupled to the end of the body so as to penetrate the heating unit (110) and be exposed to the outside, thereby allowing the heating unit (110) to move within a limited range.

[0045] In addition, the LM SHAFT (140) is provided in the guide hole (132) of the support member (130), and the LM SHAFT (140) guides the elastic body (120) located between the heating member (110) and the support member (130) to contract or expand in the forward and backward direction, while being provided so as to move the heating member (110) while moving in the forward and backward direction with the support member (130) as the center.

[0046] At this time, the support member (130) is provided with a mounting groove (133) that is inserted with a relatively larger area than the guide hole (132) centered on the guide hole (132), and an LM BUSH (141) having a catch formed on one side of the mounting groove (133) is inserted into the guide hole (132) and installed so that the catch is positioned in accordance with the mounting groove (133).

[0047] And, in this LM BUSH (141), a hole is formed in the front-back direction, and a column of an LM SHAFT (140) is inserted into the hole so as to be able to move in the front-back direction, and the column of the LM SHAFT (140) is positioned at the edge of the mounting hole (111) of the heating unit (110) with its end penetrating the elastic body (120), and a fastening means is fixed to the column of the LM SHAFT (140) by penetrating the heating unit (110).

[0048] In addition, it includes a contact surface that is in close contact with the outer surface of the spreader box (10), a pressure surface located at the rear of the contact surface, and a fixing hole (111) that penetrates the pressure surface and the contact surface in the front-back direction, and a sensor unit (112) that has a slide groove in which a heating wire (113) is fitted in the lateral direction and a fixing piece and a sensor (114) for fixing the heating wire when it is fitted in the slide groove.

[0049] Fig. 5 shows a state in which the contact surface of the elastically supported heating part is completely and completely fixed to the outer surface of the spreader box, and Fig. 6 shows a state in which the spreader boxes are provided in multiple numbers and are secondarily fixed to the spreader boxes on one side and the other side so as not to move.

[0050] With reference to this, the present invention is characterized in that when the rotary handle of the adjusting means (150) located at the center of the support member (130) is rotated in one direction, the contracted elastic body (120) expands and the heating member (110) moves forward, and the contact surface of the heating member (110) is contacted with the outer surface of the spreader box (10).

[0051] At this time, the elastic body (120) is provided on both left and right sides with the control means (150) as the center, so that even if the left and right sides of the heating unit (110) that moves forward and backward by the rotation of the control means (150) located at the center move deviately, the heating unit (110) is completely pressed against the outer surface of the spreader box (10) as a whole through the expansion of the elastic body contracted on both left and right sides, thereby preventing the heating unit (110) from being heated deviately in a gap.

[0052] In addition, when the control means (150) no longer rotates in one direction, the contact surface of the heating unit (110) and the outer surface of the spreader box (10) are completely contacted. At this time, each heating unit positioned in the front-back direction applies pressure to the outer surface of the spreader box (10) in both directions from one side and the other side to fix the spreader box.

[0053] Figures 7 and 8 show the heating part, which is attached to the outer surface of the spreader box, being pulled apart by the adjusting means.

[0054] With reference to this, the present invention is characterized in that when the rotary handle of the adjusting means (150) is rotated in the other direction while the heating part (110) is in close contact with the outer surface of the spreader box (10), the adjusting means (150) moves rearward around the support part (130), and accordingly, the heating part (110) that is elastically supported is pulled rearward to move backward.

[0055] At this time, the heating unit (110) moves backward while being elastically supported by elastic bodies (120) located on both left and right sides of the support unit (130), and the elastic bodies (120) contract in the forward and backward direction along the column of the LM SHAFT (140), while the engaging head of the LM SHAFT (140) moves backward in accordance with the movement of the heating unit (110), so that the heating unit (110) is completely separated from the spreader box (10).

[0056] And the spreader box (10) can be easily removed / installed regardless of the heating device, thereby minimizing damage to peripheral devices.

[0057] Accordingly, the present invention not only enables easy mounting and dismounting of only the spreader box (10) regardless of the heating device, but also enables the distance of the heating unit to be adjusted according to the position of the spreader box (10), and the heating unit is completely sealed against the outer surface of the spreader box without any gaps, thereby maintaining the liquid gelatin provided in the inner space of the spreader box (10) from hardening through heat transfer.
