置に関する。DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a peristaltic pump using flexible piping. More particularly, the present invention relates to an improved mounting device for a peristaltic pump on which the flexible tubing is compressed.

来る。PRIOR ART The operability of a peristaltic pump depends on the continuous and recursive compression of a length of flexible tubing which causes the outflow of fluid in the length of flexible tubing. The accuracy of the fluid flow from the peristaltic pump should be maintained only when the new flexible tubing is operable to repeat the (same) degree of compression of the flexible tubing whenever it bites into the peristaltic pump head. Can be done.

ずかしいものにしてしまつた。Since the size of the flexible pipe used and the hardness of the gyrometer are changed, there is a problem in maintaining the accuracy of the fluid discharge amount (flow rate) of the peristaltic pump. The problem of maintaining the accuracy of the liquid discharge rate is also compounded by the increasing viscosity of the fluid pumped. Furthermore, if the flexible tubing is properly positioned with respect to the pump rotor and the surface against which it is compressed, or if the pump head is slightly eccentric, the rotating pump head will be It can be squeezed in and stop the rotation of the pump head. Various attempts to overcome these problems have been made by recurring flexible tubing and adjustably mounting these portions of a continuously compressing peristaltic pump. This adjustable mount is configured to self-correct for eccentricity of the pump head itself or for irregularities in the flexible tubing. In lieu of the practical performance of these adjustable mounting devices, peristaltic pump heads have been difficult to clean and difficult to operate when the flexible tubing was placed in contact with the pump rotor.

単一のポンプヘツドと共に使用することが可能である。Means for Solving the Problems These problems of the prior art are overcome by the present invention including a floating bearing compression surface for use with a peristaltic pump. The floating support compression surface is offset with respect to the pump rotor and toward the flexible tubing so that it exerts a constant force on the flexible tubing as the pump rotor rotates. As that portion of the pump rotor repeatedly and continuously compresses the flexible tubing, the surface against which the flexible tubing is compressed rotates about the pivot mount. This rotation allows the compression surface to react to any irregularities in the pump rotor or flexible tubing. In this way it is possible to use flexible tubing of varying dimensions and gyrometer hardness with a single pump head without affecting the accuracy of the pump.

する。Peristaltic pumps typically have rollers that continuously and recoil the flexible tubing to maintain fluid flow in the flexible tubing. In order to compress the flexible pipe, it is necessary that the roller has a surface toward which the flexible pipe can be compressed. This includes a plate member having an arcuate surface against which the flexible tubing is compressed. Since this plate member is mounted on the pivot, it is rotatable with respect to the peristaltic pump head. A mechanical spring member, which is a biasing member, holds the plate member in operative engagement with the flexible tubing when the tubing is placed in operative engagement with the peristaltic pump head. In this way, the arcuate surface floats over the flexible tubing while exerting a constant force on the flexible tubing to maintain fluid flow accuracy.

み合わせておいても良い。The pump 20 comprises four main parts; in detail, a pipe guide piece 12, a flexible pipe 22, a rotary (possible) pump head 24 and a pressure plate (plate member) 10. As the pump head 24 rotates, the pressure wheel 26 contacts the flexible tubing 22,
The flexible pipe 22 is repetitively and continuously compressed. Pressure plate 10
The arcuate surface 11 of FIG. 1 operably engages the flexible tubing 22 and the pressure wheel 26 provides a surface against which the flexible tubing 22 can be compressed. If desired, the arcuate surface may be framed by a fence 13 to keep the flexible tubing 22 in operable engagement with the pump head 24 at all times.

The pressure plate 10 is held in position on the pivot bar rotatable by set screws 36. An arm 44 is attached to the opposite (backside) end of the pivot bar 14 as shown in FIGS. The electric switch 30 may be placed on the arm 44 to support the position of the arm 44.

のための面を提供させている。The pressure plate 10 is held in its position by a mechanical spring 28. The mechanical spring 28 includes a spring retainer 64, a coil portion 62, a straight portion 58, and a bend portion.
Composed of 56. The action of the straight portion 58 on the cam finger 42 biases the arm 44 downward.
This downward biasing action of arm 44 causes pressure plate 10 to remain in contact with flexible tubing 22 and provide a surface for compression of flexible tubing 22.

位置を示す。Operate the flexible tubing 22 to move the peristaltic pump to the pump head.
When attempting to operably engage 24, pressure plate 10 is moved from that position as shown in FIG. The flexible pipe 22 can then pass through the pipe guide 12 and on the pressure wheel 26, as shown in FIG. When the flexible tubing 22 is in the proper position, the pressure plate 10 is brought into position on the flexible tubing 22 by manually grasping the knob 16 and moving it into position to contact the flexible tubing 22. Can be returned. An automatic spring return device may be used if desired. As can be best seen by comparing FIGS. 3 and 4, the movement of the pressure plate 10 is
The finger 42 will slide down on the straight portion 58 of the mechanical spring 28. The electric switch 30 indicates the position of the pressure plate 10.

る力（バイアス力）を提供している。When power is applied to the motor 32 via conductor 50, rotational motion is transmitted to the drive shaft 18 through the reducer 34. The drive shaft 18 rotates the rotary pump head 24. As the pump head 24 rotates, the incompressibility of the fluid and the dimensions and gyrometer stiffness of the flexible tubing 22 cause the pressure plate 10 to move or float relative to the pivot bar 14 as the pump moves. A mechanical spring 28 provides the flexible tubing 22 with a biasing force that causes the pressure plate 10 to move closer.

動かすことによつて容易に実施される。When the required amount of fluid is pumped to the object, the rotation of the rotary pump head 24 can be stopped and the flexible pipe 22 can be removed from the peristaltic pump 20. This removal of the flexible pipe 22 is accomplished by grasping the knob 16 and raising the pressure plate 10 from the flexible pipe 22 to the position shown in FIG. As the pressure plate 10 is moved away from the rotary pump head 24, the cam finger 42 slides up along the straight portion 58 of the mechanical spring 28. When the cam finger 42 reaches the bending portion 56 of the mechanical spring 28, the coil portion is
The downward force sensed at the bend 56 caused by the action of 62 holds the pressure plate 10 open. If an automatic return device is used, the plate 10 will return to the closed position when removed. It is easily implemented by moving the pressure plate 10 back into contact with the flexible tubing 22.

性配管の凹凸に対して廻ることが出来る。In this way, the pressure plate 10 around the rotary peristaltic pump head 24 can rotate on the pivot bar against the eccentricity of the rotary pump or the irregularities of the flexible tubing.
