 Embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIG. 7, reference numeral 1 denotes a package transport path for transporting the package P to a packing section or the like in a state where the package P is placed on a tray. The transport path 1 is for a transport line 2 and a package provided on the line 2. Storage line 3 of In the illustrated example, a set of two rows of storage lines 3 is shown. The storage lines 3 are capable of temporarily storing and carrying a plurality of trays of the packages P which are being carried, together with the trays. An elevator (elevating device) 4 that connects the transfer line 2 and each stage of the storage line 3 is connected to the carry-out end and the carry-in end of the storage line 3.

Reference numeral 5 denotes a tray transport path for transporting (returning) a plurality of trays collected at the time of packing to an automatic winder or the like in a stacked state, and this transport path 5 is for transporting the trays. The transfer line 6 and a storage line 7 for the tray, which is provided on the transfer line 6 and can temporarily store and transfer stacked trays on the way of transfer. As shown in FIG. 8, the storage line 7 is divided into a plurality of stages in the frame 8 in the vertical direction, and is supported by guide rails 10 so that the stacking tray 9 does not fall sideways. In the illustrated example, the trays can be transported and stored in four stages such that the types of trays in the upper three stages and the lower one are different.

As shown in FIG. 9, the tray used in the present embodiment is formed by integrally molding pegs 11 and 12 for inserting a package in the center of a circular substrate, and the diameter of the pegs 11 and 12 is There are two different types, which are hollow from the center of the substrate to the inside of the pegs 11 and 12, and it is possible to stack a plurality of trays 13 and 14 with pegs of other trays inserted in the hollow part. You can do it. For example, 10 trays 13 as shown in FIG. 9A and 10 trays 14 as shown in FIG. 9B are stacked and conveyed as a stacking tray 9. The pegs 11 and 12 are formed in two stages with different diameters so that they can be used for two types of packages.

As shown in FIG. 7, an elevator 15 that connects the carrying line 6 and each stage of the storage line 7 is also connected to the carry-out end and the carry-in end of the storage line 7 for the tray. As shown in FIG. 2, the elevator 15 includes an elevating frame 17 having a tray guide 16 on which the stacking trays 9 are placed, and a motor 18 capable of rotating the elevating frame 17 in a forward and reverse direction. It is mainly composed. The rotation shaft of the motor 18 is formed as a screw shaft 19, and a nut 20 is screwed onto the screw shaft 19. The nut 20 is attached to the elevating frame 17, and the elevating frame 17 moves up and down along with the nut 20 along the screw shaft 19 by the rotation of the motor 18. In FIG. 2, reference numeral 21 denotes an air cylinder, and the air cylinder 21 engages a hook 22 below the stacking tray 9 to drive it, thereby raising or lowering the tray 9 of the transport or storage lines 6, 7. The tray 9 on the frame 17 or the elevating frame 17 can be transferred to the storage or transfer lines 7 and 6.

A shaft 24 is erected so as to face each other on the side frame 23 on both sides of the elevating frame 17, and the shaft 24 has a stack tray 9 as shown in FIGS. 1 and 2. A plate 25, which is curved so as to hold it, is rotatably attached. Upper and lower base portions 25a and 25b of the plate 25 are rotatably attached to the shaft 24, and a pin 26 protruding in the axial direction of the shaft 25 is attached to the lower base portion 25b as shown in FIGS. It is provided. The projecting portion of the pin 26 is located in the groove 28 provided in the circumferential direction of the casing 27 adjacent to the base portion 25b, and the rotation of the plate 25 rotates about the groove 28 about the shaft 24 times. Is regulated. That is, the groove 28 holds the transferred stacking tray 9 so as to cover it from both sides thereof, and then the plate 25 can be rotated so that the tray 9 can be transferred to the next line 6, 7 or the like. Is formed. Further, one end of a spring 29 is attached to the plate 25, and the other end of the spring 29 is attached to the shaft 24. The spring 29 causes the plate 25 to move to the position shown by the dotted line in FIG. When the stacking tray 9 is guided, the plate 25 is rotated so that the tray 9 is sandwiched by the plates 25 from both sides and sandwiched. Is becoming In addition, as shown in FIG. 2, when the tray is not placed on the elevating frame, the elevating frame is seen from the downstream side in the transport direction and has a gate shape. Further, in FIG. 3, reference numeral 35 denotes a bush.

Further, at the carry-out end of the carrying line 6, as shown in FIG. 5, a pair of plates 25 are provided on both sides thereof in substantially the same manner as described above. Further, although not shown, a pair of plates 25 are provided at the carry-in end of the storage line 7 for the tray, although not shown.

Next, the operation of this embodiment will be described.

A plurality of trays 13 and 14 collected at the time of packing are stacked, and the stacked tray 9 is placed on the transfer line 6 and transferred. Since a pair of plates 25 are provided on both sides of the carry-out end of the carrying line 6, when the stacking tray 9 enters the carry-out end, the plates 25 are rotated by the trays 9, As shown in FIG. 5, the stacking tray 9 is sandwiched by the pair of plates 25 so that the stacking tray 9 can be changed over from both sides. As a result, even if the stacking tray 9 is tilted, the stacking tray 9 is straightly corrected by the pair of plates 25.

Then, the stacking tray 25 is sent from the carry-out end of the transfer line 6 onto the elevating frame 17 of the elevator 15 by the hook 22 being operated by the air cylinder 21 shown in FIG. It is sandwiched by the pair of plates 25 so that it can be held from both sides. In this state, the elevating frame 17 moves up and down. After moving, the stacking tray 9 is sent from the lifting frame 17 to the carry-in end of the storage line 7, is placed on the storage line 7, and is also clamped from both sides by the pair of plates 25 at the carry-in end. .. Then, the stacking tray 9 is stored on the storage line 7 as needed.

Therefore, by providing the pair of plates 25 at the carry-out end of the carrying line 6, the elevating frame 17 of the elevator 15 and the carry-in end of the storage line 7, the stacked tray 9 can be carried smoothly. That is, at the carry-out end of the transfer line 6 and the carry-in end of the storage line 7, the stacking trays 9 are suddenly moved or suddenly stopped, so that the trays 9 are likely to be tilted. By providing 25, the stacking tray 25 is prevented from tilting, and even when the stacking tray 9 is tilted and conveyed, its posture is corrected. For this reason, there is no possibility that the stacking tray 9 projects by inclining toward the elevator 15 and hits the elevating frame 17 of the elevator 21 to obstruct the vertical movement of the elevating frame 17. Also, in the elevator 15, when the lifting frame 17 moves up and down, it is particularly easy to tilt, and when the lifting frame 17 is transferred to the lifting frame 17 or the storage line 7, the hook 22 is engaged below the stacking tray 9. Since the upper part of the stacking tray 9 is not supported because it is moved, the stacking tray 9 may tilt or fall down.However, by installing the pair of plates 25 at the carry-in end of the elevating frame 17 and the storage line 7, The stacking tray 9 will not tilt or fall. Therefore, the stacking tray 9 is sent from the transfer line 6 to the storage line 7 via the elevator 15 without tilting or falling. The above-mentioned pair of plates are also provided at the exit / entry end of the line for sending the stacking tray from the storage line to the transfer line via the elevator and at the elevator, but these explanations are almost the same as above. Omit it. Thus, the stacking tray 9 can be smoothly transported by providing the pair of plates 25 in the tray transport path 5 at a position where the stacking tray 9 is likely to tilt.

FIG. 6 shows another example of a pair of plates, which is different from the above-mentioned curved plates and is rotatably attached to the shaft 30 and provided at intervals of about 90 ° in the circumferential direction. It is being formed as a rotary gate 32 composed of four arms 31. The rotary gate 32 rotates 1/4 rotation each time the stacking tray 9 is inserted, and the rigidity of the rotary gate 32 prevents the stacking tray 9 from tilting or falling. By providing the pair of rotary gates 32 on both sides of the tray transport path 5 in place of the pair of plates 25 described above, the stacking trays 9 can be prevented from tilting and collapsing in a similar manner to the above. The stacking tray 9 can be sequentially sandwiched and sent one after another.
