 The problem to be solved by the present invention is to solve these problems in the past and to stack trays using mechanical force to store them, thus significantly reducing the labor and time required for stacking and storing trays. The present invention is to provide a medical tray stack storage device.

[0004]

[Means for Solving the Problems]

 The configuration of the present invention which solves such a problem is as follows: 1) A tray supply unit that supplies trays each having a stackable shape one by one, and the trays supplied from the tray supply unit are temporarily stopped at a fixed position station and the tray A station conveyor that can send out the trays on the station and a tray storage conveyor that receives and stacks the trays that are sent out from the station conveyor are installed and placed on the station of the station conveyor. Lifting the tray so that it supports the bottom tray and raises the tray to a height higher than the height of one tray, and lowers the supported tray to the position of the height of one tray of the station. Medical tray stacking storage device characterized by having a device 2) tray elevating device, A pair of left and right locking claws that support the upper collar of the lay from below, a cylinder that raises and lowers the locking claw, and a locking claw that is inserted below the collar of the tray and pivots to retract from below. The medical tray stacking storage device according to 1), which comprises a cylinder for opening and closing a nail.

[0005]

[Action]

 In the present invention, trays or empty trays containing the remaining used medicines and used medical items such as used syringes are collected or sent to the station conveyor one by one from the tray supply unit. The tray sent first is stopped on the station of the station conveyor, and is supported by the tray lifting device at this station and lifted above the height of the tray. After that, the next tray is received from the tray supply unit on the station and made stationary. Next, the tray lifting device is operated to lower the lifted tray, stack it on the next tray waiting at the station, stack it, stop the lowering, and release the support. In addition, the lifting device is operated to support the lower trays of the two stacked trays on the station, and the two stacked trays are lifted to a height higher than the height of one tray to supply the next tray. When the trays are sent from the department and stand still, the two trays that have been lifted are sent and lowered so that they stack on top of the stationary trays, forming a three-tier tray. By repeating this process, the trays are stacked in multiple stages. When a predetermined number of trays are stacked, the station conveyor operates, and the stacked trays are transferred to the tray storage conveyor, placed on the tray storage conveyor, and stored and transported.

[0006]

[Embodiment of device]

 The tray supply unit of the present invention feeds empty trays, trays collected from a patient room or new trays one by one, and is a normal belt conveyor, a conveyor such as a roller conveyor, a chute that tilts and slides by its own weight, Alternatively, a supply means such as a vertical conveyor can be used. It is desirable to automatically collect the trays on each floor of the ward by using a vertical conveyor and a horizontal belt conveyor. The station conveyor of the present invention can also be a conveyor such as a belt conveyor, a force-conveying roller conveyor, a chain conveyor, etc., which can normally feed and feed the load horizontally, and can be driven / stopped. The storage conveyor is a stack of trays that is stored and moved in multiple stages. Use a conveyor that has enough support strength so that the conveyor surface does not move even if the trays are stacked in multiple stages. A guide wall for preventing the stacked trays from falling over may be provided if necessary. In the tray elevating device of the present invention, as the elevating means for elevating and lowering a plurality of stacked trays, there are a cylinder, an endless chain stretched vertically, a link mechanism for elevating, and an elevating means using a feed screw shaft. As a means for holding the tray, a claw, a gripping hand, a horizontally moving support arm or the like can be used.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a plan view of the embodiment, FIG. 2 is a front view of the embodiment, FIG. 3 is an explanatory view showing a tray elevating device of the embodiment, and FIG. 4 is an explanatory view showing an operation of the embodiment. In the figure, 1 is a tray, 1a is a flange part of the upper part of the tray 1, 2 is a supply conveyor using a belt conveyor which is a tray supply section, 3 is a station conveyor using a belt conveyor, and 4 is a tray 1 of the station conveyor. A station for stopping the tray, 5 a tray storage conveyor using a roller conveyor, and 6 a tray lifting device. Further, in the figure, 6a to 6g are structures relating to the tray lifting device 6, 6a is a tray lifting guide column, and 6b is a pair of left and right engaging members for supporting the tray 1 by engaging with the lower surface of the collar portion 1a of the tray 1. Stop claw, 6c is a mounting plate pivotally supporting the locking claw, 6d is a pivot of the locking claw 6b, 6e is a cylinder for moving the mounting plate 6c up and down, 6f is a claw opening / closing for rotating the locking claw 6c A cylinder, 6g, is a sensor for detecting that the tray 1 has reached the position of the height of one tray. In this embodiment, the tray 1 in which empty trays or medical items collected from a hospital room are partially stored is sent from the supply conveyor 2 to the station conveyor 3, and the tray 1 is stationed by the station conveyor 3. Move to 4 and stop at this position. The tray lifting device 6 operates in synchronization with this stop. First, the cylinder 6e operates in a contracting direction to lower the mounting plate 6c to a position lower than the height of the tray 1, and the claw opening / closing cylinder 6f is operated at this position. The cylinder 6f rotates the locking claw 6b around the pivot 6d and inserts the locking claw 6b below the collar 1a of the tray 1 on the station 4. In this state, the cylinder 6e is operated, and the tray 1 is lifted by the pair of left and right engaging pawls 6b that extend the rod. The tray 1 is held at a position higher than the height of one tray, and the next tray 1 is Wait for Station 4. When the next tray 1 arrives at the station and becomes stationary, the cylinder 6e operates in the direction of contracting the rod, lowers the locking claw 6b and the tray 1 supported thereby, and stops the stationary tray 1 on the station 4 waiting. It is piled up on top and the state is detected by the sensor 6g, and the cylinder 6e is stopped. After that, the cylinder 6f for opening and closing the claw is operated, the locking claw 6b is rotated, and the tray 1 is retracted from below the collar portion 1a. The cylinder 6e is operated with the locking claw 6b retracted, the locking claw 6b and the mounting plate 6c are lowered to the tray 1 at the lowermost stage, and the cylinder 6f is operated at the lowered position to lock the locking claw 6f. Is rotated and inserted below the collar portion 1a of the lowermost tray 1, so that the tray 1 can be supported. After that, the cylinder 6e is operated to raise all the stacked trays by a height of one tray or more, and waits as it is until the next tray 1 comes to rest on the station 4. By repeating the above tray stacking, a predetermined number of trays are stacked. When the trays 1 are stacked one by one, the locking claws 6b are retracted, the station conveyor 3 is operated, and the trays are stored on the next tray storage conveyor 5, and the trays 1 are stored in the tray storage conveyor 5 in a stacked state. Then, it is transported for the next processing as needed. The operation of these device cylinders, conveyors, etc. is automatically performed by a control device (not shown), and trays are stacked and moved automatically.

[0008]
