  Therefore, in view of the above problems, the present invention suppresses complication of the entire configuration of the liquid medicine supply device, and even when handling a suspension liquid medicine, the liquid medicine is suspended in the liquid medicine bottle. It is an object to provide a liquid medicine supply device that can be supplied.

  The liquid medicine supply device of the present invention includes a supply pump for supplying liquid medicine from the inside of the supply bottle to an opening of the liquid medicine bottle via a supply pipe, and a control device for controlling the drive of the supply pump. The control device has a function of switching the drive of the supply pump between a liquid medicine supply state for supplying liquid medicine to the liquid medicine bottle and a liquid medicine stirring state for stirring the liquid medicine in the supply bottle, In the liquid medicine supply state, the control device sucks the liquid medicine into the supply pipe from the one end tip of the supply pipe by driving the supply pump to rotate forward, and the opening of the liquid medicine bottle from the other end tip of the supply pipe In the liquid medicine agitation state, the liquid medicine is sucked into the supply pipe from the one end tip of the supply pipe and the water is drawn from the other end tip of the supply pipe. To prevent the medicine from being discharged, the feed pump is driven in reverse to supply the liquid medicine. It is characterized in that it is configured to be able to be returned to the Le.

In the above configuration, in the liquid medicine supply state, the controller drives the supply pump in the normal direction and continues this, whereby the liquid medicine is sucked from the one end tip of the supply pipe and sent to the other end tip side. The liquid medicine is discharged from the tip of the other end toward the opening of the liquid medicine bottle and supplied to the liquid medicine bottle.
In the liquid medicine agitation state, the control device drives the supply pump to rotate forward so that the liquid medicine is sucked from the tip end of one end of the supply pipe and sent to the tip end of the other end. Before discharging from the front end portion (before discharging), the control device reversely drives the supply pump. Then, the liquid medicine sucked into the supply pipe is returned again to the supply bottle, and since the liquid medicine is returned by driving the supply pump, the liquid medicine itself is agitated by the returned water flow.

The liquid medicine supply device of the present invention is characterized in that a liquid medicine reservoir having an enlarged diameter of the supply pipe is provided in the middle of the supply pipe.
According to this configuration, in the liquid medicine stirring state, the liquid medicine is sufficiently stirred by the amount of liquid medicine corresponding to the amount stored in the liquid reservoir without lengthening the supply pipe.

The elevating device 25 is driven by operating the drive switch, and the supply nozzle attached to the nozzle mounting plate 53 is operated. The mounting table 24 is raised until the liquid medicine 2 can be supplied from 22 to the supply bottle 3.

  The main body 37 of each supply pump 18 is detachably attached to the upper surface of the nozzle attachment plate 53 via an attachment frame 36 by screwing or the like. The supply pump 18 includes a driven gear 41 that meshes with the drive gear 47 and interlocks with the drive.

  A pump drive unit 20 for driving the supply pump 18 individually and selectively is provided. The pump drive unit 20 is disposed radially inward of a region surrounded by the attachment frame 36. The pump drive unit 20 includes a supply motor 54 (a stepping motor is used) held horizontally, and the drive gear 47 provided at the tip of the drive shaft.

  As shown in FIGS. 4 and 5, the supply pump 18 presses a midway part of the supply pipe 29 and moves the pressed part from the supply bottle 3 side to the liquid medicine bottle 4 side, so that the inside of the supply bottle 3 The liquid medicine 2 is configured to move to the liquid medicine bottle 4 side. The supply pump 18 is provided with clamping means composed of a pair of members that are relatively close to and away from each other, and the clamping means presses and deforms the intermediate portion of the supply pipe 29 by bringing the members close to each other. Thus, the supply pipe 29 can be inserted between the members. In other words, the supply pump 18 deforms the supply pipe 29 against its elasticity by the clamping means, thereby moving the negative pressure state in the supply pipe 29 from the supply bottle 3 side to the supply nozzle 22 side for supply. The liquid medicine 2 is sucked into the pipe 29, and the sucked liquid medicine 2 is moved from the supply bottle 3 side to the supply nozzle 22 side.

That is, the supply pump 18 is fixed to the nozzle mounting plate 53 side, the vertical movement member 100 capable of moving up and down by operating a lever (not shown) with respect to the main body 37 and holding the position thereof. And a rotary clamping member 102 provided on the main body 37 side. The clamping means includes a vertical movement member 100 and a rotary clamping member 102.
The vertical movement member 100 has an inverted U-shaped concave portion 101 on its lower surface, and a middle portion of the supply pipe 29 between the rotary clamping member 102 provided on the main body portion 37 side and the concave portion 101 of the vertical movement member 100. Can be sandwiched. The wall surface of the recess 101 has an upper arc surface 103 and a suspended surface 104 depending from both the left and right sides of the arc surface 103.

  The vertical movement member 100 is arranged at the upper portion of the main body 37 near the front side, and the rotary clamping member 102 is arranged at a position facing the concave portion 101 of the vertical movement member 100 in the downward direction. Thus, the vertical movement member 100 and the rotation clamping member 102 are configured to be relatively close to each other in the vertical direction.

The rotary clamping member 102 further includes a drive shaft 105 that rotates as the supply motor 54 is driven, and front and rear rotary disks 106 that are provided on the outer peripheral portion on the distal end side of the drive shaft 105 so as to rotate integrally with the drive shaft 105. And a plurality of (in this case, three) roller-shaped rotary pressing bodies 107 that rotate by contacting the supply pipe 29 and revolve around the drive shaft 105 along with the rotation of the rotating disk 106.
The rotary pressing body 107 is supported so as to be rotatable around a support shaft 108 in the front-rear direction, and the support shaft 108 is supported between the rotary disks 106 in parallel with the drive shaft 105. Is set so as to protrude further outward from the outer peripheral portion of the rotating disk 106.

In the supply pump 18 having such a configuration, the supply pipe 29 is directed from the front to the rear between the vertical movement member 100 and the rotary clamping member 102 by operating the lever to move the vertical movement member 100 upward. After the insertion, the lever is operated again to lower the vertical movement member 100.
By doing so, the supply pipe 29 is sandwiched and pressed between the rotary clamping member 102, in particular, the rotary pressing body 107 and the arc surface 103 of the recess 101, and the supply pipe 29 is deformed so as to be crushed in the radial direction. Is done. Then, by rotating the rotary clamping member 102 around the drive shaft 105 (for example, clockwise in FIG. 5), the deformed portion of the supply pipe 29 moves to the liquid medicine bottle 4 side, and a negative pressure / positive pressure region is provided in the supply pipe 29. Occurs, the liquid medicine 2 in the supply bottle 3 is sucked into the supply pipe 29 and sequentially moves to the liquid medicine bottle 4 side.

  As described above, in order to supply the liquid medicine 2 to the liquid medicine bottle 4, a rotation operation around the axis of the drive shaft 105 is required. The drive shaft 105 rotates along with the rotation of the driven gear 41 around the axis. For this purpose, the driving gear 47 is moved in the horizontal direction by driving a moving device 52 described later, and the driving gear 47 is meshed (fitted) with the driven gear 41 whose distance from the vertical axis 16 is immovable.

As described above, the one end tip portion 29 a of the supply pipe 29 opened is inserted into the bottom portion of the supply bottle 3 and immersed in the liquid medicine 2, and the supply nozzle 22 is attached to the other end tip portion of the supply pipe 29. The middle portion of the supply pipe 29 is detachably held by the supply pump 18. Further, in the supply pipe 29, the staying portion S processed into a meandering shape, a spiral shape, a winding shape, etc. from the tip end portion 29 a to the middle portion sandwiched by the supply pump 18 (on the downstream side of the supply pump 18). Thus, the supply pipe 29 has a predetermined length necessary for stirring the liquid medicine 2. In other words, by providing the retention part S, the amount of the liquid medicine 2 that can be retained in the entire supply pipe 29 is retained in a limited space as compared with the supply pipe 29 in which the retention part S is not provided. be able to.
That is, when the supply pump 18 is driven forward, the liquid medicine 2 is sucked from the one end tip portion 29a of the supply pipe 29 and moves to the supply nozzle 22 side. Therefore, in a state where the sufficient amount of the liquid medicine 2 is filled in the supply bottle 3, the liquid medicine 2 is at least a stay part until the liquid medicine 2 is sucked and discharged from the supply nozzle 22. As a result, the liquid medicine 2 is present in the supply pipe 29 more than in the case where the stay portion S is not provided.
In this embodiment, the supply pipe 29 is provided for each supply bottle 3 (supply pump 18), and each supply pipe 29 has a retention portion S. These staying parts S are accommodated in a predetermined place so as not to get in the way.

  The supply operation of the liquid medicine 2 and the stirring operation of the liquid medicine 2 are controlled by the control device M. As shown in FIG. 6, the supply start switch W is connected to the input side of the control device M, and the driving units of the rotation motor 28 and the supply motor 54 are connected to the output side of the control device M.

Next, the operation of the liquid medicine supply device 1 having the above configuration will be described based on the function of the control device M that controls the operation of the liquid medicine supply device 1.
First, when the supply start switch W laid on the liquid medicine supply device 1 is operated to start supply, the control device M drives the rotation motor 28 (rotation drive unit 17) so as to select the supply bottle 3 to be used alone. The nozzle mounting plate 53 and the mounting body 5 are rotated by a predetermined angle around the vertical axis 16 as necessary so that the supply bottle 3 to be used is positioned so as to face the front side of the operator. .
Subsequently, the control device M drives the moving device 52 (moving motor 58) to move the driving gear 47 in the horizontal direction, and engages (fits) the driving gear 47 with the driven gear 41 to supply motor. By driving 54, the drive gear 47 rotates, the driven gear 41 meshing with it rotates, the intermediate portion of the supply pipe 29 is deformed by the rotary pressing body 107, and the deformation moves to the supply nozzle 22 side. As a result, the liquid medicine 2 is sucked into the supply pipe 29 and moved to the supply nozzle 22 side, and the rotation of the driven gear 41 is continued, so that the liquid medicine 2 is supplied from the supply nozzle 22 to the liquid medicine bottle 4. The liquid is discharged toward the opening and supplied to the liquid medicine bottle 4.
In order to perform such an operation separately for the supply bottle 3 to be used, the control device M drives the rotating motor 28 to intermittently place the mounting body 5 and the nozzle mounting plate 53 around the vertical axis 16. The required amount and the required type of liquid medicine 2 are supplied to the liquid medicine bottle 4.

  In the case where the liquid medicine 2 is suspendable, the components constituting the liquid medicine 2 are separated with the passage of time unless some stirring operation is performed on the liquid medicine 2. And if the liquid medicine 2 in the isolate | separated state will be supplied to the liquid medicine bottle 4, there exists a problem that the effect of the liquid medicine 2 cannot be exhibited. Therefore, in order to stir the liquid medicine 2 in the supply bottle 3, for example, the control device M, prior to supplying the liquid medicine 2 from each supply bottle 3 to the liquid medicine bottle 4, the liquid medicine in each supply bottle 3. The drive of the supply pump 18 is controlled so that 2 is stirred.

Specifically, the control device M drives the supply motor 54 (supply pump 18) until the liquid medicine 2 is sucked into all the regions of the staying part S having a preset length, and performs a predetermined process. An amount of liquid medicine 2 is sucked into the supply pipe 29.
At this time, the control device M includes, as information, the storage amount associated with the length of the supply pipe 29, and when the supply pump 18 is in a stirring state, the control apparatus M provides the supply nozzle 22 of the supply pipe 29. The driving time of the supply motor 54 is limited so that the liquid medicine 2 is not discharged from the liquid.
Thereafter, the control device M reversely drives the supply motor 54 for a time corresponding to the liquid medicine 2 that is sucked into the supply pipe 29. Then, the liquid medicine 2 is returned from the one end tip portion 29 a of the supply pipe 29 into the supply bottle 3. At this time, since the liquid medicine 2 is returned by the drive of the supply pump 18, it has a constant water flow (hydraulic force), and is therefore well mixed with the liquid medicine 2 in the supply bottle 3 and sufficiently agitated. can do.
Subsequently, the control device M supplies the liquid medicine 2 to the liquid medicine bottle 4 by driving the supply motor 54 in the normal rotation again in the supply state. In this case, the control device M controls the supply motor 54 to perform only normal rotation driving so as to reach a preset supply amount of the liquid medicine 2. And since the liquid medicine 2 is fully stirred beforehand, it is supplied to the liquid medicine bottle 4 in the suspended state, and the fall of the effect as the liquid medicine 2 is prevented.

  In this way, the means for stirring the liquid medicine 2 in the supply bottle 3 is realized by controlling the drive of the supply motor 54 provided originally, and the supply pipe 29 provided originally is simply extended. Since the agitation means is constituted by a simple configuration, the liquid medicine 2 is suspended in the suspended state even when the suspension liquid medicine 2 is handled while suppressing the complexity of the whole liquid medicine supply device 1. The medicine bottle 4 can be supplied.

In the above embodiment, the stirring means of the supply pipe 29 is configured so that the liquid medicine 2 in the supply bottle 3 can be sufficiently stirred using a configuration in which the supply pipe 29 is lengthened. However, the present invention is not limited to this. is not.
For example, as shown in another embodiment of FIG. 7, the liquid medicine 2 in the supply bottle 3 is provided by providing a liquid reservoir 50 of the liquid medicine 2 having an enlarged diameter in the middle of the supply pipe 29 as a stirring means. It is also possible to stir.
In this case, the control of the drive of the supply motor 54 in the control device M is the same as in the above embodiment, but the liquid medicine 50 is agitated by providing the liquid reservoir 50 without increasing the length of the supply pipe 29. Since a sufficient amount of the liquid medicine 2 can be stored in the liquid reservoir 50, the suspension liquid medicine 2 is handled while suppressing the complexity of the entire liquid medicine supply device 1. The liquid medicine 2 can be supplied to the liquid medicine bottle 4 in a suspended state.

In the embodiment of FIG. 7, the liquid reservoir 50 is arranged upstream of the supply pump 18 in the supply direction of the liquid medicine 2, but the liquid reservoir 50 is more liquid 2 than the supply pump 18. It is good also as a structure arrange | positioned in the downstream of the supply direction. Furthermore, the liquid reservoir 50 may be configured to be disposed on both sides of the supply direction with respect to the supply pump 18, and in any case, when handling the suspension liquid medicine 2 as in the above embodiment. Even if it is, the liquid medicine 2 can be supplied to the liquid medicine bottle 4 in a suspended state.
The liquid reservoir 50 may be configured by enlarging a part of the supply pipe 29, or the liquid reservoir 50 itself is formed separately from the supply pipe 29, and this is formed in the middle of the supply pipe 29. You may make it connect to.

  In each of the above-described embodiments, when the liquid medicine 2 is agitated, the example in which the forward drive and the reverse drive of the supply pump 18 are performed only once is shown, but the liquid medicine 2 is not discharged from the supply nozzle 22. The control device M may perform control so that the forward rotation drive and the reverse drive of the supply pump 18 are repeated a plurality of times. If the forward drive and the reverse drive of the supply pump 18 are repeated a plurality of times, the liquid medicine 2 in the supply bottle 3 can be stirred more reliably, and the liquid medicine 2 is suspended in the liquid medicine bottle 4. Can be supplied to.

  In each of the above embodiments, the supply pipe 29 is lengthened or the liquid reservoir 50 is provided to secure the amount in the supply pipe 29 so that the liquid medicine 2 is sufficiently stirred. Without changing the length of the supply pipe 29 and without providing the liquid reservoir 50, the forward rotation drive and the reverse drive of the drive of the supply motor 54 in the control device M are repeated several times little by little, thereby supplying bottles If the liquid medicine 2 in 3 can be sufficiently stirred, a method of stirring the liquid medicine 2 only by controlling the driving of the supply motor 54 in the control device M is also preferable.
