Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is used in a granular chemical dissolution apparatus that puts granular chemical stored in a bottle into a dissolution tank, mixes and agitates with a predetermined amount of solvent, and stocks the dissolved solution, and is provided at the spout of the bottle. The present invention relates to an unsealing apparatus for a granular chemical dissolving apparatus for unsealing a sealing member.
[0002]
[Prior art and problems to be solved by the invention]
2. Description of the Related Art Conventionally, a loading port provided in a dissolving apparatus has its axis line set in a vertical direction, and a loading port of a bottle filled with a flowing chemical is directed downward.
[0003]
The loading unit provided with the loading port is provided with an opening device.
[0004]
The opening device has a cylindrical main body corresponding to an aluminum opening seal (seal member) provided at the spout of the bottle. The cylinder diameter of the main body is slightly smaller than the diameter dimension of the spout of the bottle loaded in the loading port, and a plurality of triangular blades (opening blades) are formed on the opposite end surface around the entire circumference of the end surface. It is formed leaving a part. The main body and the blade portion are collectively referred to as a cylindrical blade.
[0005]
The cylindrical blade has a radial direction in which the blade portion is not formed by the cam mechanism, and rotates about an axis whose axis is the horizontal direction. In a state where the bottle is loaded, the bottle is separated from the opening seal of the bottle. Here, when the opening operation is started, the blade portion of the opening device is pierced into the opening seal with the urging force of the urging means. This piercing operation may be repeated several times.
[0006]
As a result, the opening seal cannot withstand the weight of the internal granular chemical, breaks, the internal granular chemical flows out, and reaches the dissolution tank provided below the loading portion of the dissolution apparatus.
[0007]
At this time, the blade portion does not extend over the entire circumference of the end surface of the cylindrical main body as described above, and there is a portion where the blade portion does not exist. For this reason, the opening seal is not completely separated from the bottle by the non-breaking portion of the portion where the blade portion does not exist, and prevents the opening seal from dropping into the dissolution tank. That is, for example, when a can is opened by opening a can opener, the opening seal is supported on the bottle side by providing the same function as the hinge function except for a part of the circumference to be opened. .
[0008]
Here, it is sufficient that the opening seal is opened by about 90 ° and retracted from the inner space of the completely cylindrical blade body. However, the fracture surface of the opening seal has a so-called jagged shape, and a convex whiskers. May occur. The convex whiskers may be caught on the inner peripheral surface of the cylindrical blade, and the opening seal may not be completely retracted. If the unsealed seal remains in this inner space, it will be the resistance of the falling granular chemical, which will result in the granular chemical being scattered in the loading port.
[0009]
If the scattered granular chemicals are solidified, the cam blade prevents the cylindrical blade from rotating, and as a result, there is a problem that the opening seal cannot be opened.
[0010]
In consideration of the above facts, the present invention improves the passage of granular chemicals from the loading port to the dissolution tank, and prevents the movement of the cylindrical blade by the opening mechanism due to the retention and solidification of the granular chemicals for a long period of time. It is an object to obtain a granular chemical unsealing apparatus for a granular chemical dissolving apparatus.
[0011]
[Means for Solving the Problems]
The invention according to claim 1 is used in a granular chemical dissolution apparatus that puts granular chemical stored in a bottle into a dissolution tank, mixes and agitates with a predetermined amount of solvent, and stocks the dissolved solution. An opening device for a granular chemical dissolution apparatus for opening a sealing member provided at a spout, a loading portion provided with a loading port into which the spout of the bottle can be inserted vertically downward, and a cylindrical shape A main body formed on the cylindrical body, a blade portion formed on one circumferential end surface of the cylindrical main body facing the loading port, and provided on the other circumferential end surface of the cylindrical main body. The part where the blade is not formed Cylindrical body in a predetermined range centered on the farthest position A cylindrical blade provided with a notch for shortening the cylindrical length of the cylindrical body, and an inner space of the main body in the loading section, and the cylindrical blade is disposed outside the cylindrical main body by a driving force of a driving means. An opening mechanism that rotates about a horizontal axis and allows the blade to penetrate the seal member until the notch reaches the seal member.
[0012]
According to the first aspect of the present invention, when the bottle is set in the loading port of the loading unit and the opening mechanism is operated, the cylindrical blade rotates and penetrates the sealing member provided in the spout of the bottle. To do. This penetration amount is preferably performed up to the notch position. If this operation is repeated several times as necessary, the sealing member cannot withstand the weight of the granular medicine filled in the bottle, and breaks and the granular medicine flows out.
[0013]
By the way, the penetration of the sealing member by the cylindrical blade does not form a blade portion in a part of the cylindrical main body, and therefore this portion does not break and remains on the bottle side (from the diameter of the cylindrical blade portion). The larger part). This part of the sealing member acts as a hinge, and the sealing member is pressed by the granular medicine and moves to a position that is substantially perpendicular to the opening of the spout of the bottle.
[0014]
At this time, the seal member passes through the inner space of the cylindrical main body, but in the invention of claim 1, there is no member constituting the opening mechanism portion or the like in the inner space of the main body, Moreover, since the notch is provided, the seal member is immediately opened by the weight of the granular medicine. For this reason, it is solved that the inner space of the main body, that is, the flow path of the granular medicine is blocked by the resistance force caused by sliding in contact with the inner periphery of the main body.
[0015]
In addition, the notch extends over about 1/3 of the circumference of the cylindrical main body.
[0016]
As a result, the granular chemical reaches the dissolution tank through the regular drop flow path, and is dispersed in the inner space of the main body and the vicinity thereof to be solidified.
[0017]
If the granular chemical falls properly into the dissolution tank, it does not adversely affect the movement of the cylindrical blade by the opening mechanism, so that maintenance is not required over a long period of time, and workability is improved.
[0018]
According to a second aspect of the present invention, in the first aspect of the present invention, a reinforcing member is attached to the cylindrical main body so that the wall thickness is larger than the blade thickness of the blade portion. It is characterized by that.
[0019]
According to the invention described in claim 2, the normal blade portion is formed with the same wall thickness as that of the cylindrical main body on which the blade portion is formed, but the main body needs to have a predetermined rigidity. For this reason, the blade portion has a wall thickness that is larger than necessary. For this reason, when the seal member is pierced and is broken by the weight of the granular medicine, the fracture surface is deformed in the thickness direction in proportion to the thickness of the blade portion (convex whiskers). Due to this deformation, the seal member is easily caught when it comes into sliding contact with the inner space of the main body. In addition, the convex whiskers may become chips and fall into the dissolution tank, and the chips may cause clogging of the solution flow path of the dissolution tank or clogging of the filter. .
[0020]
For this reason, according to the second aspect, the thickness of the blade portion is set to be appropriate for the blade portion, and the portion in which the rigidity of the main body cannot be maintained by this is eliminated by attaching the reinforcing member. By reducing the thickness of the blade portion, it is possible to eliminate the sticking of the seal member and to prevent the convex whiskers from becoming chips and falling into the melting tank.
[0021]
The appropriate thickness of the blade is about 0.2 mm to 0.5 mm, preferably 0.3 mm.
[0022]
Further, the blade portion is often made of stainless steel in order to prevent deterioration due to the granular chemical, but the granular chemical is likely to adhere to the stainless steel blade portion. For this reason, by applying Teflon coating to the surface of the blade portion, it is possible to improve the slipperiness against the granular chemical, prevent the granular chemical from adhering to the blade portion, and maintain the breakability of the sealing member. be able to.
[0023]

[0059]
A cylindrical member 256 is disposed between the pair of brackets 252 and coaxially with the circular hole 254, and both end surfaces in the axial direction are welded to the bracket 252. Note that two through holes 258 in the diameter direction are provided on the outer periphery of the cylindrical member 256.
[0060]
On the other hand, the lever member 37 is supported so as to be rotatable around a fulcrum shaft 86. The lever member 37 and the cylindrical blade 38 are fixed, and the lever member 37 and the cylindrical blade 38 rotate integrally around a fulcrum shaft 86.
[0061]
Further, the lever member 37 and the cylindrical blade 38 are connected to the developing bottle 104 (fixing bottle 104F) in which the lever member 37 and the cylindrical blade 38 are held by the holding portion 36 by a torsion coil spring 87 fitted around the fulcrum shaft 86. It is urged in a direction in which the opening 126 abuts (a direction in which the lever member 37 rotates counterclockwise in FIG. 10).
[0062]

Therefore, the cam follower 74 rotates around the shaft 83 integrally with the driven gear 84. Further, the shaft 83 is rotatably supported by a support bracket 92 attached to the frame body 61 via a sliding bearing 91 (FIG. 11).
[0064]
In FIG. 10, the state of the lever member 37 in the initial position where one end of the lever member 37 is separated from the opening 126 of the bottle 104 (104F) is indicated by a solid line, and the seal member 128 sealing the opening 126 is broken through. The lever member 37 in the state is indicated by a two-dot chain line. Whether or not the lever member 37 is in the initial position is detected by a position detection sensor 94 supported by the frame body 61.
[0065]

[0066]
Hereinafter, the detailed structure of the cylindrical blade 38 will be described.
[0067]
As shown in FIG. 8, the cylindrical blade 38 is constituted by the main body 250 and the bracket 252 as described above, and the main body 250 is formed of a plate material having a wall thickness of 0.8 mm.
[0068]
A circular opening blade 260 is provided at the circular upper end of the main body 250. The unsealing blade 260 is formed with a plurality of blade portions whose upper end surface has a saw blade shape (triangular shape). The thickness of the opening blade 260 is 0.3 mm, and the rigidity of the opening blade 260 is low. However, by being supported (welded) to the main body 250, the overall rigidity of the cylindrical blade 38 is high, and blade spillage and deformation do not occur.
[0069]
The opening blade 260 is pierced into the seal member 128 of the bottle 104 (104F) with vigor, so that the seal member 128 can be broken according to the pitch of the blade inserted into the seal member 128. When the seal member 128 is broken, the support force of the granular chemical inside the bottle by the seal member 128 is reduced.
[0070]
Due to the decrease in the supporting force, the granular chemical is configured to press the seal member 128 and flow out.
[0071]
Here, the opening blade 260 is a part of the circumferential direction (between the pair of brackets 252) so that the sealing member 128 is not cut out in a complete circumferential shape and is partly connected without being cut. It is set as the structure which does not have a saw blade. 8 and 11, a range B is a range where no saw blade is provided.
[0072]
With such a configuration, the seal member 128 is opened while rotating around the hinge while the portion remaining corresponding to the portion not having the saw blade has a function as a hinge and is pressed by the granular medicine. The
[0073]
As shown in FIG. 8, a notch 262 is formed at a lower end of the main body 250 in a predetermined range (1/3 of the circumference) around the position farthest from the position where the bracket 252 is attached. ing.
[0074]
The tube length direction of the notch 262 reaches a position close to the opening blade 260. When the opening blade 260 breaks the seal member 128, the notch 262 enters the inside of the bottle 104 (104F). ing.
[0075]
For this reason, when the seal member 128 is pressed and released by the granular medicine after being broken, there is no member that prevents this movement in the opening direction, and the seal member 128 is opened in a state of hardly contacting the main body 250.
[0076]
Here, since the notch portion 262 has not been formed in the main body 250 conventionally, the convex whiskers of the fracture surface of the seal member 128 formed when the opening blade 260 is broken are the bottom of the opening blade 260 and the main body 250. There is a case where it is not completely opened due to being caught with the inner peripheral surface of the lens or the bracket for supporting the cylindrical blade 38 of the lever member 128 described above.
[0077]
On the other hand, in the present embodiment, the bracket for supporting the cylindrical blade 38 is excluded from the inner peripheral surface side of the main body 250 to form the notch portion 262, and the seal member 128 is notched at the time of breakage. Therefore, the seal member 128 does not receive any resistance force and can be smoothly fully opened (open approximately 90 °).
[0078]
Further, the surface of the main body 250 and the opening blade 260 is coated with Teflon, and the sliding of the seal member 128 with respect to the inner periphery of the main body 250 is improved.
[0079]
The operation of this embodiment will be described below.
[0080]
The loading port 106 of the first dissolution processing unit 116 is loaded with a bottle 104 in which granules containing chemicals necessary for the development replenisher are stored, and the loading port 106F of the second dissolution processing unit 118 is loaded with A bottle 104F in which granules containing chemicals necessary for the fixing replenisher are stored is loaded. When each bottle 104 (104F) is loaded into the loading port 106 (106F), a cap (not shown) is removed, the bottle 104 (104F) is turned upside down (the pouring port 124 faces downward), and the pouring port 124 is placed into the loading port 106. Insert into (106F). The sizes of these bottles 104 (104F) are almost the same, but can be distinguished by color (the developing bottle 104 is red translucent and the fixing bottle 104F is white translucent). Can be easily distinguished. Further, as shown in FIGS. 6A and 7A, the shape of the spout 124 of the bottle 104 (104F) is slightly different. For example, even when working in a dark room, there is no mistake.
[0081]
Since the opening 126 of the spout 124 is sealed by a thin seal member 128, the granular chemical does not flow out during the loading stage.
[0082]
When loading of the bottle 104 (104F) (one set of two) is completed, the corresponding display lamp on the operation / display panel 132 is turned on. When the operation key is pressed in this state, the bottle 104 (104F) enters a waiting state for opening the seal member 128.
[0083]
The opening time is the initial stage of operation (the stirring tank 154 (154F) and the stock tank 156 (156F) are both empty) and the remaining amount in the stock tank 156 (156F) is 10 liters. At this time, the water supply pump 212 (212F) is operated and water is supplied from the water supply tank 206 until the level terminal 170C is detected, and then the stirring blade 166 (166F) is rotated by the motor 168 (168F). Then, the corresponding display lamp 148 starts blinking, and an opening operation is performed.
(Opening operation)
When the bottle 104 (104F) is not opened, as shown in FIG. 12A, the cylindrical cam follower 74 is stopped at the upper limit position, and the engagement between the cam follower 74 and the groove-shaped portion 88 The lever member 37 is fixed in an initial state (a state in which the separation distance between the cylindrical blade 38 at one end of the lever member 37 and the opening 126 of the bottle 104 (104F) is maximum).
[0084]
Further, when the lever member 37 is in the initial state, it is detected by the position detection sensor 94.
[0085]
Then, when the bottle 104 (104F) needs to be opened, a controller (not shown) rotates the disk 90 counterclockwise as shown in FIG. At the initial stage of rotation, as shown in FIG. 12B, the cam follower 74 gradually advances in the groove-shaped portion 88 according to the effect of the position of the cam follower 74 accompanying the rotation of the disk 90, and accordingly, the lever member Slow rotation of the lever member 37 is started so that one end side of 37 faces the opening 126 of the bottle 104 (104F).
[0086]
Further, when the rotation of the disk 90 advances and the cam follower 74 comes out of the groove-shaped portion 88 of the plate cam 70 and moves to the semicircular hole portion 89 (see FIG. 10), as shown in FIG. The cam follower 74 and the groove-shaped portion 88 are disengaged, and the lever member 37 can be rotated at a high speed in a counterclockwise direction.
[0087]
At this time, the lever member 37 is rotated at a high speed by the biasing force of the torsion coil spring 87. However, the biasing force of the torsion coil spring 87 is not so great that the cylindrical blade 38 completely penetrates the seal member 128 that seals the opening 126 of the bottle 104 (104F).
[0088]
Accordingly, when the seal member 128 is in an unopened state, the rotation of the lever member 37 is temporarily stopped with the tip of the blade of the cylindrical blade 38 hit as shown in FIG.
[0089]
Then, as shown in FIG. 12E, the cam follower 74 is half a month until the cam follower 74 on the rotating disk 90 comes into contact with the outer peripheral edge adjacent to the groove-shaped portion 88 of the guide groove 72 of the plate cam 70. Transmission of the rotational force from the driving force conversion mechanism 76 (see FIG. 10) to the lever member 37, which is in a state of crossing the hole 89, is stopped.
[0090]
When the disk 90 further rotates and the cam follower 74 on the disk 90 comes into contact with the outer peripheral edge adjacent to the groove-shaped portion 88 of the guide groove 72 of the plate cam 70 as shown in FIG. The rotational force is transmitted from 74 to the plate cam 70, the lever member 37 is rotated by the driving torque of the motor 78, and the cutting edge of the cylindrical blade 38 seals the bottle 104 (104F). Begin to break through.
[0091]
When the disk 90 further rotates, the disk 90 enters the groove-shaped portion 88 of the cam follower 74, and the operation of the cylindrical blade 38 breaking through the seal member 128 is completed as shown in FIG. (The cam follower 74 is at a position close to the lowest limit). At the same time that the seal member 128 is pierced, the seal member 128 is lowered by its own weight, and the granular drug falls.
[0092]
Accordingly, one end side of the lever member 37 is lowered, the pierced seal member 128 is opened, and the granular medicine in the bottle 104 (104F) falls into the stirring tank 154 (154F).
[0093]
Note that the saw blade of the cylindrical blade 38 that breaks through the seal member 128 is provided only in a range excluding the range B (FIG. 11) on the fulcrum shaft 86 side of the lever member 37. Thus, there is no inconvenience that the cut end of the seal member 128 falls into the stirring tank 154 (154F).
[0094]
Thereafter, when the disk 90 further rotates, the cam follower 74 moves the groove portion 88 toward the hole portion 89 along the upper edge of the groove portion 88 as shown in FIG.
[0095]
When the disk 90 rotates once and the cam follower 74 returns to the upper limit position, the lever member 37 also returns to the initial posture, and this is detected by the position detection sensor 94. That is, when the disk 90 rotates once, the opening operation of the seal member 128 by the lever member 37 is achieved once.
[0096]
The rotating operation of the disk 90 is repeatedly performed five times. In the second and subsequent opening operations, as shown in FIG. 12 (C), the lever member 37 immediately rotates to the maximum extent, and a part of the lever member 37 or the cylindrical blade 38 opens the bottle 104 (104F). Part of 126 is struck, and the granular chemical remaining in the bottle 104 (104F) is dropped into the stirring tank 154 (154F) by impact to prevent the occurrence of inconvenience such as residual granular chemical.
[0097]
Here, as shown in FIG. 8, the cylindrical blade 38 of the present embodiment has a notch 262 formed at the lower end portion of the main body 250, and the depth when the opening blade 260 pierces the seal member 128. However, it reaches the notch 262.
[0098]
For this reason, after the seal member 128 is broken, the seal member 128 cannot withstand the weight of the granular chemical and is released by being pressed by the granular chemical. A whisker is not in contact with the inner periphery of the cylindrical main body 250. Further, since the bracket 252 is located outside the outer periphery of the main body 250 and the mounting position with the seal member 128 is located outside the outer periphery of the main body 250, the inside of the main body 250 is completely transparent. Therefore, the granular chemical smoothly pushes down the seal member 128 (rotates the seal member 128 by approximately 90 °) and falls straight into the agitation tank 154.
[0099]
Compared with the prior art, since the notch portion 262 does not exist in the prior art, the convex beard on the outer periphery of the seal member 128 generated by piercing with an opening blade and breaking by the weight of granular chemicals is a cylindrical main body The seal member 128 could not be pushed down smoothly. In addition, since the attachment position with the lever member 128 exists inside the cylindrical main body, the seal member 128 is not completely opened, and a part of the granular medicine that falls into the stirring tank 154 while being scattered accumulates at this attachment position. , Solidified.
[0100]
However, in the present embodiment, the bracket for supporting the cylindrical blade 38 is excluded from the inner peripheral surface side of the main body 250 to form the cutout portion 262 and the seal member 128 reaches the cutout portion 262 at the time of breakage. As a result, the inside of the main body 250 is completely threaded, and even if a convex whiskers are present on the seal member 128, it does not receive any resistance, and can be smoothly fully opened (open approximately 90 °). Can do. In addition, the granular chemical is not deposited on the way to the stirring tank 154. Furthermore, since the cylindrical blade 38 is coated with Teflon, the granular medicine can slide well, and part of it can be prevented from adhering to the inner periphery of the main body 250.
[0101]
As described above, the structure is such that unnecessary members do not exist in the flow path from the loading port 106 for loading the bottle 104 (104F) upside down to the stirring tank 154, and the main body 250 of the cylindrical blade 38 has a large notch 262. Since the contact between the seal member 128 and the inner peripheral surface of the main body 250 is minimized as much as possible when the seal member 128 is moved after being broken, the seal member 128 is smoothly and surely completely opened (rotated by about 90 °) and granular. The chemical can be dropped straight down to the stirring tank 154.
[0102]
【The invention's effect】
As described above, the opening device of the granular chemical dissolution apparatus according to the present invention improves the passage of the granular chemical from the loading port to the dissolution tank, and the movement of the cylindrical blade by the opening mechanism is caused by the retention and solidification of the granular chemical. It has an excellent effect that it can be prevented for a long time.
