Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a device for transporting an object using a support base surrounded by an endless belt, particularly for transporting a patient in a hospital or the like from one room to another through a room. The present invention relates to a transfer device that can be suitably used when transferring to another room.

←) Prior art This type of transfer device is used as a device B for carrying patients in and out of an external room through a sterilized operating room or the like. In other words, if a patient is transported into or out of a sterilized operating room using a transport vehicle or the like through a door, bacteria may enter the operating room and sterilization will need to be performed again. The method used is to install a loading/unloading device in the window of the operating room and to carry the patient in/out through the window.

This transfer device has a support table for scooping up, mounting, and transferring a patient lying on an operating table, etc., but this support table has a flat frame that is supported so as to be horizontally movable in a horizontal state. The basic component is an endless belt that is placed around the frame in the patient transport direction, and the patient is transported by rotation of the endless belt and movement of the frame.

An example of such a device is shown in Japanese Patent Application Laid-Open No. 53-16487, ``Transportation device for moving a lying patient, especially in a hospital.'' This "carrying device" is based on two upper and lower frames and endless belts surrounding both frames, and the lower endless belt is actively rotated by a drive mechanism. This "carrying device" is a system in which the lower endless belt of the upper and lower artist belts is actively rotated, and the upper endless belt is driven by frictional force. There is a problem with the reliability of belt rotation. Furthermore, there is also a problem in the speed of patient transfer, and there is also the drawback that it is difficult to rotate the upper endless belt smoothly.

This type of patient transfer device does not adopt the above-mentioned system that uses two upper and lower endless belts, but a simple structure that uses only one endless belt (Special Publication No. 57-3).
No. 373 ``Object Transfer Device'') has also been proposed, but this ``transfer device'' is a system in which an endless belt is frictionally connected to a bed, etc. and rotated by the movement of a frame, and it is used for scooping up and transferring patients. There is a problem with certainty.

1) Purpose The present invention is an object transfer device that solves the drawbacks of the conventional devices as described above, and provides an ideal transfer device that can drive the rotation of an endless belt at a fixed position. 0) Structure The object transfer device of the present invention is characterized by the structure of a support base on which an object is placed and transferred. In other words, this support base includes a main frame that supports the object to be loaded, two end lobes arranged at both ends of the frame in the transport direction, and a figure-of-eight tube between the frame and both end lobes. It is constituted by a group of endless band-like bodies in which multiple rows of wound narrow-width endless band-like bodies are wound. A drive mechanism for rotating the endless strip and a movable mechanism for vertically moving the support base are provided, as well as a guide mechanism for guiding the support base in the horizontal direction.

By the cooperative operation of these mechanisms, objects are scooped up from one side of the support base, received, and transferred to the other side. There are many types of endless strips, but they are unique in that they are constructed with one strip for the upper and lower sides, in contrast to the conventional method of providing separate strips for the upper and lower sides.

(e) Examples An embodiment of the patient transfer device will be described below.

Figure 1 shows partition ai! This is a diagram showing the overall configuration of the transfer device of the present invention implemented in the window M of the W. A support stand S, which is the main body of the device, is installed through the window M and extends into the outer room A and the operating room B. This indicates the state in which the

Although the figure shows the window M open, specifically, an opening/closing window that descends to the top surface of the support base S is provided, and FIG. 1 shows this opening/closing window (not shown). This is a diagram in which ``Z'' is omitted. In the figure, the patient K is placed on the transport vehicle H in the outer room A, and the state before the patient K is transferred to the operating table in the operating room B is shown.

The details of the configuration of the support stand S will be described later, but its main components are a frame 1 for mounting and supporting the patient K, loaves 2 at both ends, and an endless belt 3 (narrow width belt) surrounding these in the direction of transport of the patient. Endless band group).

This support stand S is horizontally supported through the window part M, and is movable back and forth in the horizontal direction.

The support stand S is specially constructed with a frame l#C for transporting the patient K.
- The continuous endless belt 3 is configured to be actively rotated, and is also configured to be able to move a certain amount in the vertical direction.

Details of these configurations will be explained with reference to FIGS. 2 to 7.

FIG. 2 is a perspective view showing how the patient transfer device shown in FIG. The movable mechanism for vertical movement is located within the partition wall W and does not appear outside, as will be described later.

The support stand S is supported via a support frame 4 by a movable box R installed movably up and down relative to the partition wall W, and at the same time is supported so as to be movable in the horizontal direction. Reference numeral 4H designates a horizontal guide hole drilled in the support frame 4 for this purpose, into which a support loaf 6 consisting of a movable box is inserted, as will be described later.

In order to make it easier to understand, the figure shows an example of the narrow endless belt 3 being wound around 10 belts at regular intervals.In reality, however, the narrow endless belt 3 is designed to almost cover the top surface of the frame 1 with no gaps. is desirable. In addition, since it is a narrow endless belt, the frame 1 and guide roller I
R and an endless belt 3 on each end loaf 2
It is desirable to form a four-part groove with a width equal to the width of the endless belt 3 so that the endless belt 3 does not fluctuate in the lateral direction (lateral vibration).

Each of the endless belts 3 is wound around the guide loaf IR and both end rollers 2 and is in contact with each other, but these are the same endless belts, that is, one endless belt 3 is wound around the guide loaf IR and both end rollers 2. 2. It is wound in a figure 8 shape for 2. This point is a feature of the present invention.

The support mechanism and movable mechanism of the support stand S are shown in FIGS. 3 to 5, and FIG. 3 is a perspective view of the relationship between the support stand S, particularly the frame 1, the support frame 4, and the movable box R that supports them. In the figure, the narrow endless belt 3 is completely removed and the support frame 4 is partially cut away.

The guide loaf IR and both end rollers 2 are fixed in position and rotatably held relative to the frame 1 via the support frame 4. That is, the frame 1 is fixed to the support frame 4 by a fixing port 5, and the guide loaf IR and both end loaves 2 are rotatably held by the support frame 4 via bearings at their respective support shafts IR8.28.

The support frame 4 disposed on both sides of the support stand S is provided with guide holes 4H as described above, and the support loaf 6 rotatably held by the movable box H is fitted into the guide hole 4H.

A pinion 7 engages with a hook 4G installed on the lower surface of the guide hole 4H, and is rotationally driven by an electric motor 14 as shown in FIG. That is, the rotation of the electric motor 14 is transmitted to the worm 12 via the bevel gear mechanism 13, and is further transmitted to the worm gear 11 meshing with the worm 12 to reduce the speed, and is then transmitted to the timing pulley 1o. The rotation of the timing pulley 1o is transmitted to the pinion support shaft 78 via the timing belt 9 and the timing pulley 8, thereby driving the pinion 7 to rotate. Since the pinion 7 and its support shaft 78 are rotated at a fixed position relative to the movable box R, the rotation causes the support frame 4 to move in the horizontal direction from the relationship between the guide hole 4 and the support p-flow.

The electric motor 14 is a reversible electric motor, and when rotated while the amount and direction of rotation are controlled by a control circuit as described later, the support frame 4 is displaced to a desired position. Electric motor 1
The pinion 7 is not rotated by the acting force of the support frame 4 and has a locking function due to the intervention of the worm reduction mechanism in which the pinion 4 is not actively rotated.

Each endless belt 3 is wound in a figure 8 shape around the loaf 2 at both ends of the frame 1, and each endless belt 3 is rotated around the loaf 2 at both ends of the frame 1. However, as shown in FIG. 1, the endless belt 3 is wound around the drive roller 2o under the frame 1 under pressure. Reference numeral 21 denotes a guide loaf that guides the endless belt 3 so as to lengthen the winding portion around the drive loaf 2o.

In FIG. 4, reference numeral 15 denotes an electric motor that rotationally drives the driving loaf 20, which is held in the movable box R and transmits rotational force to the transmission shaft 18 through a transmission mechanism of gears 16 and 17. The rotation of the transmission shaft 18 is transmitted to the support shaft 208 of the drive loaf 20 via the clutch 19.

The movable box R that supports the support stand S and the mechanism that realizes horizontal movement are as described above, and the configurations of both movable boxes R, the drive roller 20, etc. are shown in FIG.

FIG. 5 shows these structures in a perspective view, and the support stand S is shown virtually. Most of the components shown in FIG. 5 are provided inside the partition wall W, as shown in FIG. 2.

FIG. 5 shows a configuration in which the movable box R moves up and down relative to the fixed part 1, and the drive lobe 2o and guide loaf 21 also move up and down due to the up and down movement of the movable box. This is because the drive loaf 20 and the guide loaf 21 are held between the two movable boxes R%R. The support stand S moves up and down through the up and down movement of both movable boxes R%R.

The vertical movement of the movable box R is performed by the rotational output of the electric motor 22, and the vertical movement guidance is performed by a guide frame WGK- which is a part of the partition wall W.

As shown in the figure, the movable box Rt is provided with through holes RH at corresponding positions in the vertical direction, and a rack RG is installed on the vertical side surface of the hole. Further, each of the through holes RH of both movable boxes R has an electric motor 22.
A drive shaft 24 which is rotationally driven by the rack RG passes through the rack RG, and a pinion 25 fixed to the drive shaft 24 meshes with the rack RG.

23 is a transmission that reduces the rotational output of the electric motor 22 and transmits it to the drive shaft 24, and the drive shaft 24 is rotatably held by the frame F. Therefore, when the electric motor 22 is controlled as described later and driven to rotate in the desired forward and reverse directions, the movable boxes R and R move up and down by a predetermined amount. This amount of vertical movement may be small as described later.

The operation of the rotational drive transmission 15 for the support stand S, especially its small width drain belt 3, the drive electric motor 14 for horizontally moving the support stand S, and the drive electric motor 22 for moving the movable box R up and down is controlled by the patient. The transfer is performed sequentially, and these operations can be performed as appropriate by operating the operation button P and on/off switch T on the operation box 26, as shown in FIG. That is, signals from the operation box 26 are input to a controller 27, which outputs signals necessary to operate the electric motors 14, 15 and 22, as will be described later. 28 is electric g, S+
% 82 , Ss is a switching circuit that controls the operation of the electric motor MA14.15.22 by a signal from the 1 controller 27. The electric AL114.15.22 is a reversible motor, and the controller 27 sends either a signal for forward rotation or reverse rotation to the switching circuits s, , 82, and S5 based on the signal t from the operation box 26, and performs switching. The circuits 8N, 82sSx also control the rotation direction of each electric motor 14, 15.22 based on the signals.

Although the control system diagram shown in FIG. 7 schematically shows the basic configuration, various devices are specifically added.

Although the on/off control method is illustrated in which the operation button P is held down and the button P is stopped from being moved or transferred to a patient, the on/off control method is not limited to the illustrated example. It is also possible to input this value when it is set in advance or when the patient transfer distance is known, and to control the movement of the endless belt or support base in accordance with this input value. You may input a digital value,
Furthermore, it is also possible to install a microcomputer to control the amount of movement and the amount of rotation of the endless belt to match the set values. In such a specific device, various functions,
It is also possible to add equipment.

With the above configuration, transport to the patient will be explained with reference to FIG. FIGS. 6(1) to 6(4) show the order of transfer, and also show the order of operation of this cylinder making.

In addition, in FIG. 6, the relationship between the support stand S and the patient is shown in the IIA diagram. In particular, regarding the support stand S, one narrow width beltless belt 3, both end loaves 2, a frame 1, a driving loaf 2o, and a guide loaf 21, which are directly related to patient transfer, are shown as representatives. Furthermore, in FIG. 6, the endless belt 3 is marked with black circles or triangular arrows at regular intervals on the line of the belt, but the belts marked with black circles are displaced relative to the partition wall W. The triangular arrow indicates that it is not moving, that is, it is in a stationary state, and that the triangular arrow is displaced relative to the partition wall W, that is, that it is moving in the direction of the arrow.

In the illustrated example, an operation will be described in which a patient K on an operating table is transferred through a partition wall W to a transport vehicle H in an outer room.

Further, it is assumed that the vertical movement and horizontal movement of the drive loaf 6 and the support base S are performed by the operations described above.

First, it is necessary to advance the support table S toward the operating table. If the support table S is located on the outside room side as shown in Figure (1), the support table moving mechanism must be operated, that is, the drive The electric motor 14 is rotated to rotationally drive the pinion 7 that meshes with the rack 4G. - The reason for moving the support stand S in this way is that if the upper surface of the endless belt 3 comes into contact with a member, wall, etc. of the outer chamber when the support stand S is moved, damage due to contact with it (damage due to sliding contact) may occur. This is to prevent

The support table S moves and reaches the position of the operating table, but as this state progresses further, the support table S moves forward while the upper and lower surfaces of the endless belt 3 remain stationary against the fixed part t. Therefore, the right end of the support table S enters between the patient and the operating table. As a result, the support stand S scoops up the patient K, as shown in Figure (2).
The state will be as follows.

Figure (2) shows a state in which the rotational drive of the drive electric motor 14 has been stopped and the lifting up of the patient has been completed.

When the patient has been scooped up from the operating table, the patient K is then transferred to the outside room. In this case, first, the driving electric motor 22 is driven to rotate. Then, as shown in FIG. 6 (3), the support table S rises slightly and the endless belt 3 separates from the operating table. In this state, patient K is transferred to transport vehicle H.
When transferring to the side, the electric motor 15 is driven to rotate. This sharpening motor 14 is stopped, so the pinion 7 does not rotate, and the horizontal movement of the support base S is prevented.

Then, the drive loaf 20 is driven to rotate, and each group of narrow endless belts 3 is rotated (in the direction of the arrow) and transported to the right on the frame 1 to the patient. At this time, it is necessary to take the left end position of the support stand S in Figure (4) into consideration and transport the patient K to the right from this position on the belt 3.

Next, to move the patient K to the transport vehicle H in the outer room, the electric motor 1
4 to move the support stand S horizontally to the right to the position shown in Figure (4). Then, the electric motor 15 is driven again to support the support base S.
Transfer the patient K to the right end and position it on the transport vehicle H, then rotate the electric motor 22 in the opposite direction to move the movable box R downward (lower) to the same height as in Figure (2). Saposition H
to be restored.

FIG. (4) is a diagram showing the state after the return.

Next, an operation is performed to lower the patient K from the transport vehicle HK, but for this purpose, the drive electric motor 14 is rotated in the opposite direction and the support table 8 is horizontally moved to the left. Then, the upper and lower surfaces of the endless belt 3 become stationary relative to the fixed part, and the patient is placed on the carrier H by moving to the left while maintaining the position shown in Figure (4). You will be taken off.

In this way, the transfer of the patient from the operating table to the transport vehicle H is completed, but in the case of transfer in the reverse direction, the rotation direction of the electric motors 14, 15 is driven in the opposite direction.

The present invention is not limited to the illustrated example, and various modified embodiments are possible. First, the frame, which is the main component of the support base, is formed by joining plate-shaped bodies in the illustrated example, but in other cases, for example, a large number of rollers are arranged between both side plates, and the entire periphery of the frame is formed. It is also possible to surround an endless belt. It is desirable that the tip of the frame be formed as thin as possible.

Further, in the illustrated example, the drive roller is configured to move up and down integrally with the up and down movement of the support base. This is because the drive lobe is held in a movable box, but the movable box and the drive lobe may be separate bodies and the drive lobe may be held in a fixed position and rotated. In this case, it is also possible to make the guide row 21 shown in the illustrated example movable left and right so that the slack and tension of the endless belt 3 due to the vertical movement of the support base S can be adjusted by this row. The guide roller IR is not necessarily required.

The horizontal movement of the support stand can also be performed manually, but in this case it is necessary to provide a mechanism for preventing (locking) the horizontal movement of the support stand S when rotating the endless belt.

The device of the invention can transport not only patients but also other heavy objects. In this case, a caterpillar is used instead of a belt.
It is preferable to use Therefore, the invention is not limited to belts only.

(f) Effects As described above, the object transfer device of the present invention can transport objects more reliably than conventional devices. In particular, since the endless conveyor A/) itself, which is arranged around the frame on which the object is mounted, is actively driven and rotated, the mounted object can be reliably transferred. “Furthermore, the entire support base does not slide into contact with other fixed parts, and especially when the surrounding endless band-like body comes into contact with the fixed part, it eliminates the state of relative displacement and forms a stationary state. Moreover, the object can be transferred without causing damage to the endless strip.

It can be effectively used as a patient transport device in hospitals, and its effects are remarkable. In particular, although it is necessary to provide multiple rows of beltless bays, the belts in contact with the loading surface and the bottom surface are both of the same belt /L'), that is, there is one belt /L'), and two belts, upper and lower, are A. Compared to the method using the /), there is no malfunction of the tablet drive (rotation), and smooth object transfer is guaranteed.
