Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The bag holding apparatus according to the present embodiment is for holding a bag containing a dialysis drug in powder form (including granules) for producing a dialysate to be supplied to a dialysis machine. As shown in FIG. 4, the bag body sent out by the bag body conveying device 1 is sequentially sandwiched and sent to the bag opening device 3 in the next step. Further, after opening with the bag opening device 3, the contents can be dissolved by the dissolving device 4 . In the figure, various devices for dialysis drugs of either agent A or agent B are shown, and similar devices are necessary for other dialysis drugs.

  Here, as shown in FIG. 12, the bag body H is formed from a flexible bag-like member (soft vinyl material or the like) that is made self-supporting and having a discharge port portion Ha for discharging contents. Become. The bag body H contains a predetermined amount of powdered dialysis drug as the contents inside the bag-shaped member, and the contents can be discharged from the discharge port portion Ha fixed to the upper part thereof. is there. The discharge port portion Ha (spout) is made of a relatively hard resin molded product or the like, and a flange portion Haa protruding in a convex shape is formed on the outer peripheral surface. In addition, a film Hb is attached to the upper opening (discharge port) of the discharge port portion Ha so that the contents do not overflow, and the inside of the bag body H is in a sealed state.

  As shown in FIG. 2, the bag transport apparatus 1 is mainly composed of a plurality of pallet-shaped placing means 5 and take-out means 7 including a pusher disposed at the take-out position A. The placing means 5 can place each bag body H in an upright state and can move sequentially from the upstream side to the take-out position A, and each lower part is connected by a chain 6 suspended in an annular shape, It is comprised so that it can move along a conveyance path | route. That is, when the chain 6 is rotated by driving a motor or the like (not shown), the placing means 5 moves along the conveying direction, so that the bag body H before opening is placed on the placing means 5 on the upstream side. If it does, it will be conveyed to the extraction position A. Each placement means 5 is formed with a standing wall portion 5a for holding the bag body H on the placement surface. Instead of the chain 6, a belt or the like that can connect and move the mounting means 5 may be used.

  The take-out means 7 can move the bag H on the placement means 5 at the take-out position A to a position B off the transfer path by moving in a direction substantially perpendicular to the transfer direction by a drive source (not shown). Is. At the position B, the correcting means 10, the positioning means 8 and the clamping means 11 constituting the bag body clamping device 2 are arranged. According to such a bag body conveying apparatus 1, the bag body H before opening can be sent out to the bag body clamping apparatus 2, and a plurality of bag bodies H can be accommodated, the bag bodies H can be sequentially sent out, and the bag body clamping apparatus 2 can be sent. A series of operations such as clamping (including positioning operation and correction operation) can be automatically performed.

  Here, the bag body clamping device 2 is in a state where the bag body H sequentially sent out by the bag body conveying device 1 is clamped and fixed, and the bag body opening device 3 can perform the opening operation. As described above, the correction means 10, the positioning means 8, and the clamping means 11 are provided. The correcting means 10 can correct the direction of the discharge port portion Ha in the bag body H so as to have a predetermined direction. As shown in FIG. 3, the correction means 10 is a pair disposed at a height substantially equal to the discharge port portion Ha. The pressing means 10a.

  That is, since the bag body H is made of a flexible member such as a vinyl material, the bag body H may be bent as a whole as shown in FIG. In this case, the discharge port portion Ha is inclined by the angle α, and the opening of the discharge port portion Ha (the opening portion to which the film Hb is adhered) and the suction port 8a of the positioning means 8 described later are not opposed to each other. Thus, the suction by the positioning means 8 becomes difficult.

  Therefore, according to the correction means 10, correction is performed so that the pair of pressing means 10 a is pressed while moving toward the discharge port portion Ha, and the discharge port portion Ha is directed upward (predetermined direction). (Refer to (b) in the figure). Therefore, before the discharge port portion Ha is positioned in the vertical direction by the positioning means 8, the correction means 10 can correct the direction of the discharge port portion Ha with respect to the bag body H so as to have a predetermined direction. The positioning by can be performed reliably and easily.

  The positioning means 8 can be positioned at a predetermined height by displacing the discharge port portion Ha in the vertical direction, and as shown in FIG. It can be brought into contact with and separated from the opening) to which the film Hb is attached. The suction port 8a of the positioning unit 8 communicates with the negative pressure generating unit 9, and the suction port 8a contacts the film Hb at the discharge port portion Ha projection, thereby sucking and adsorbing the projection at a negative pressure. To get.

  Then, the positioning means 8 is further lowered while maintaining the suction state, and the discharge port Ha is displaced downward. Thus, the height dimension of the bag body H (the height from the bottom surface of the bag body H to the protruding end of the discharge port section Ha) in which the discharge port section Ha is opposed to the suction port 8a of the positioning means 8 by the correcting means 10. When the dimension is H1 (see FIG. 5A), the positioning means 8 can be lowered until the height dimension becomes H2.

  Thereafter, the positioning means 8 is raised while maintaining the suction state, and the discharge port portion Ha is displaced upward so that the height dimension of the bag body H becomes H3 (see FIG. 10C). That is, when the height dimension of the bag body H is H3, the discharge port portion Ha is set to a predetermined height so as to be substantially equal to the height of the claw portion 11a of the clamping means 11 described later. Therefore, since the discharge port portion Ha is displaced in the vertical direction and positioned at a predetermined height, the discharge port portion Ha in the bag body H in which the discharge port portion Ha is formed can be stably supported by the clamping means. Can be pinched.

  In the above description, the negative pressure generating means 9 is driven to bring the discharge port portion Ha into close contact with the suction port 8a both when the positioning device 8 is lowered and when it is raised. It is also possible to adopt a configuration in which the close contact state is set only when Ha is displaced upward, and the negative pressure generating means 9 is stopped and not closely contacted when lowered (when the discharge port portion Ha is displaced downward).

  However, the ejection port portion Ha is clamped by the clamping unit 11 while the discharge port portion Ha is positioned at a predetermined height by the positioning unit 8. As shown in FIGS. 5 to 8, the clamping unit 11 includes a pair of claw portions 11 a disposed at a height substantially equal to the discharge port portion Ha positioned by the positioning unit 8, and the width direction of the bag body H. And a pair of side surface support portions 11b arranged with a separation dimension corresponding to the above.

  The claw portions 11a swing around the swing axis C so as to be close to each other and can be separated from each other. As shown in FIGS. It is comprised so that it can be clamped. Moreover, the groove | channel 11aa which can be fitted with the collar part Haa formed in the discharge outlet part Ha is each formed in the inner side (surface which mutually faces) of the nail | claw part 11a, and the said nail | claw part 11a is connected with the discharge outlet part Ha. It can be fitted and firmly clamped.

  Here, the clamping means 11 can be turned upside down while pinching the discharge port portion Ha of the bag body H, so that the contents can be taken out downward (note that the upside down operation will be described later). This is performed after connection with the bag opening device 3 is performed). Thereby, the holding operation of the bag body and the operation of taking out the contents can be continuously performed, and workability can be improved. On the other hand, as shown in FIG. 8, the side surface support portion 11 b is configured so as to be close to or abut on the side surface of the bag body H with the claw portion 11 a sandwiching the discharge port portion Ha. When H is turned upside down, the side surface of the bag body H is supported by the side surface support portion 11b, and the shape of the entire bag body H can be maintained to some extent. For example, the clamping operation and the upside down operation can be facilitated by forming the clamping means 11 at the tip of an air-driven or motor-driven robot hand.

  The bag opening device 3 is capable of tearing and opening the film Hb attached to the opening of the discharge port Ha, and as shown in FIGS. 9 and 10, an inlet joint 3a, an outlet joint 3b, The blades 12a and 12b and the gasket G are mainly configured. As shown in FIG. 10, the cutting tools 12a and 12b are inserted into grooves 3d and 3e formed in a substantially cross shape, and are fixed by screws N2.

  The inlet joint 3a and the outlet joint 3b are internally formed with flow paths 3aa and 3ba and are connected to the pipes L1 and L2 in FIG. 11, respectively. The flow path 3aa can guide the water (including the liquid in the dissolution process) flowing in from the pipe L2 to the side on which the blades 12a and 12b are attached. The flow path 3ba is a water (dissolution process) from the blades 12a and 12b side. Of the liquid) can be led to the pipe L1 side.

The gasket G is fixed by a ring R attached by a screw N1, and can be liquid-tightly sealed by coming into contact with the opening edge of the discharge port Ha when the film Hb is opened. That is, when the bag opening device 3 is connected to the discharge port Ha, the blades 12a, 12b tear and open the film Hb, and at the same time, the gasket G comes into contact with the opening edge and the flow paths 3aa, 3ba and the bag H The inside can be sealed liquid-tightly.

  Then, when the holding means 11 is reversed and the bag body H is turned upside down, as shown in FIG. 11, the bag body H is connected to the melting device 4 while being upside down from the self-standing state. As shown in the figure, the dissolution apparatus 4 includes a dissolution switch 13 in which a float switch F1 is disposed and is connected to a water supply source 18, and is disposed below the dissolution tank 13, And a storage tank 14 provided with a float switch F2. The dissolution tank 13 and the storage tank 14 are connected via a pipe L3, and an electromagnetic valve 16 is connected to the middle of the pipe L3.

  Furthermore, the dissolution tank 13 and the bag opening device 3 are connected via pipes L1 and L2, and a pump 15 is connected to the middle of the pipe L2. More specifically, the end of the pipe L1 is connected to the inlet joint 3a of the bag opening device 3 and the end of the pipe L2 is connected to the outlet joint 3b. (Including the liquid in the dissolution process) flows, and the water reaches the bag body H through the flow path 3aa, is led to the flow path 3ba together with the contents, and is discharged to the dissolution tank 13 through the pipe L1. It is configured.

  That is, water (including the liquid in the dissolution process) circulates between the dissolution tank 13 and the bag body H, and the contents in the bag body H are taken out and dissolved in the process. The dissolved dialysis drug is stored in the dissolution tank 13 as a dialysis stock solution, and is opened and stored in the lower storage tank 14 by opening the electromagnetic valve 16, via the discharge line L 4. Sequentially discharged to the dialysis machine side. In addition, the code | symbol L5 and 17 in the figure has shown the air filter arrange | positioned in the middle of the piping which connects the storage tank 14 (similarly the dissolution tank 13) and the exterior, and the said piping L5.

Next, the effect | action in the said bag body clamping apparatus 2 is demonstrated.
The unopened bag body H sequentially sent out from the bag transport apparatus 1 is maintained in the standing state at the position B, and the discharge port portion Ha is corrected in a predetermined direction by the pressing of the pressing means 10a in the correcting means 10. (See FIG. 3). Thereafter, as the positioning means 8 is lowered and raised, and the height dimension of the bag body H is sequentially changed to H1, H2, and H3, the discharge port portion Ha is displaced up and down to a predetermined height (the clamping means 11). (Nearly the same height as the claw portion 11a) (see FIG. 4).

  Thereafter, the clamping means 11 is slid in the direction of the arrow in FIG. 6 by a driving means (not shown), and the side support portion 11b is positioned on the side surface of the bag body H by approaching the bag body H. The discharge port portion Ha is clamped by swinging about the swing shaft C (see FIGS. 7 and 8). The claw portion 11a starts to close when the positioning means 8 is attracted to the film Hb, and when the positioning means 8 is closed to some extent, the negative pressure generating means 9 is stopped to release the suction, and then the groove 11aa is surely secured to the flange Haa. The claws 11a are controlled to close until they are fitted.

  Thereby, in the clamping state, as shown in the figure, the claw portion 11a is brought into a state of being fitted to the flange portion Haa of the discharge port portion Ha, and a firm clamping is performed. Then, the bag opening device 3 is liquid-tightly connected to the discharge port Ha while maintaining the clamping, the film Hb is cut and opened by the blades 12a and 12b, and then the clamping means 11 is turned upside down. Thereby, the bag body H is in a state opposite to the self-supporting state, and the contents are easily taken out by gravity.

  Thus, a series of operations of the bag body sandwiching device 2 is completed, and then the melting by the melting device 4 is performed. Next, dissolution will be described below. First, water for dissolution is supplied from the water supply source 18 into the dissolution tank 13, and a predetermined amount of water (with a capacity to dissolve the dialysis drug contained in one bag H is detected by the float switch F1. Water). At this time, the electromagnetic valve 16 is closed. When the pump 15 is driven, the water in the dissolution tank 13 reaches the bag body H through the pipe L2 and the flow path 3aa, and enters the flow path 3ba together with the contents in the bag H (dialysis drug). After being guided, the fluid flows to the dissolution tank 13 through the pipe L1. Since a large amount of water does not need to flow when the pump 15 is in operation, it can be set to a low flow rate using an inverter or the like.

  Accordingly, water (including the liquid in the dissolution process) circulates between the dissolution tank 13 and the bag body H, all the contents in the bag body H are taken out, and the circulating liquid has a uniform concentration. At this point, the pump 15 is stopped. Thus, since the dialysis stock solution adjusted to a predetermined concentration is stored in the dissolution tank 13, the electromagnetic valve 16 is opened and the dialysis stock solution is dropped and stored on the storage tank 14 side. Can do.

According to the above embodiment, the discharge port portion Ha is displaced in the vertical direction and positioned at a predetermined height (the height of the claw portion 11a of the clamping means 11), so that it can be self-supporting while containing powdered contents. The discharge port portion Ha in the bag body H in which the discharge port portion Ha for discharging the contents is formed can be stably held by the holding means 11 . Further, the positioning means 8 attracts the discharge port portion Ha of the bag body H at a negative pressure and moves up and down in the adsorbed state, so that the discharge port portion Ha is raised to a predetermined height (the nail portion 11a of the clamping means 11). Therefore, if the application and release of the negative pressure are controlled, the discharge port portion Ha of the bag body H that is sent out can be sequentially positioned.

  Further, since the claw portion 11a of the clamping means 11 can be fitted and clamped to the flange portion Haa of the discharge port portion Ha, it can be clamped more firmly, and the subsequent operation (opening etc.) while being clamped is ensured. Can be done. Still further, the holding means 11 can be turned upside down while holding the discharge port portion Ha of the bag body H, and the contents can be taken out downward. Operation can be performed continuously, and workability can be improved.

  Since the bag body H naturally stands up and can stand on its own, and the discharge port portion Ha made of a hard material (hard resin or the like) is formed on the upper portion, the bag body opening device 3 as in this embodiment is provided. On the other hand, the liquid-tight connection can be easily made, and the opening operation and the dissolution can be performed smoothly and easily. In addition, since it has a flange portion Haa formed in a convex shape on the outer peripheral surface of the discharge port portion Ha, the operator can hook and hold the finger on the flange portion Haa, can improve the transportability, For example, the workability at the time of carrying into the bag transport apparatus 1 can be improved.

  Although the present embodiment has been described above, the present invention is not limited to these embodiments, and the correction means 10 may be of another form, or a plurality of bags having a plurality of ridges of the discharge port portion of the bag body may be sandwiched. May be. For example, as shown in FIG. 13, the correcting means 10 is constituted by a swinging member 10a ′ that can swing around a swinging axis P, and the tip of the correcting member 10 is moved in the swinging process of the swinging member 10a ′. It may be hooked on the part Ha2 so that the discharge port part Ha faces upward (see FIG. 5B). In this case, a reversible motor or the like can be used as a drive source for the swing member 10a '.

  Further, as shown in the figure, at the discharge port portion Ha of the bag body H, two hook portions Ha1 and Ha2 are formed at the top and bottom, and the tip of the swinging member 10a ′ is hooked on the lower hook portion Ha2 for correction. At the same time, the clamping means 11 may be fitted into the upper flange Ha1 and clamped. Here, in a state where the tip of the swinging member 10a ′ is hooked on the flange portion Ha2, swinging is continued until the discharge port portion Ha reaches a predetermined height (substantially the same height as the claw portion 11a in the clamping means 11). For example, the swinging member 10a ′ can simultaneously correct the direction of the discharge port portion Ha and position the height, and the separate positioning means 8 can be dispensed with.

  Further, the bag body H may have a substantially flat bottom surface to improve the self-supporting property. For example, as shown in FIGS. 14 and 15, if the discharge ports H′a, H ″ a are formed above the bag bodies H ′, H ″ whose bottom surfaces are maintained substantially flat, the bag bodies are formed. As a result, the dispersion of the positions of the discharge ports H′a and H ″ a can be reduced.

  On the other hand, the positioning means only needs to be able to be positioned at a predetermined height (substantially the same height as the clamping position by the clamping means) by displacing the discharge port portion of the bag body in the vertical direction, and by the negative pressure as in this embodiment. Instead of the one to be adsorbed, it may be displaced in the vertical direction by fitting with the discharge port portion or the like. Moreover, in this embodiment, although it is comprised so that the content may be melt | dissolved by connecting to the bag body opening apparatus 3, after tearing and opening the film Hb, the clamping means 11 is turned upside down and the discharge port You may comprise so that the content may be dropped to the dissolution tank 13 from the opening part of the part Ha.

  In this embodiment, the bag transport apparatus 1 moves a plurality of mounting means by a chain or a belt and transports it to the take-out position. A general-purpose transport device may be used. The contents stored in the bag H may be other powders instead of the dialysis drug as in this embodiment.
