る。(Prior Art) Conventionally, tray transport vehicles have been widely used in cigarette manufacturing factories to transport rolled cigarettes from winding machines to packaging machines, and their structure consists of a rectangular frame 1 as shown in FIG. A tray partition frame 4 in which a plurality of partition pieces 4' are provided at equal intervals on a trolley 3 which is provided with wheels 2a and 2b for one wheel on the front, rear, left and right sides respectively.
is erected on one side, and a tray mounting table 6 is mounted and fixed on which a plurality of tray partition protrusions 5 are formed on the upper surface corresponding to the partition pieces 4'. Note that 7 is a gripping rod for operating the tray transport vehicle.

後退方向のみに運行するように装着されている。 However, since conventional tray transport vehicles generally mainly move forward or backward in the A-A' direction, the wheels 2a attached to the front and rear of the frame 1 are mounted with the upper surface formed into a circular part 8. It is attached to the metal fitting 9 and rotatably attached to the plate 10 fixed to the frame 1 at the circular part 8 via a bearing, but the wheels 2b attached to the left and right sides of the frame 1 are always rotatable. Since the operation of the transport vehicle becomes unstable, the mounting brackets 9 of the left and right wheels 2b are fixed to the plate 10, and the wheels 2b are mounted so as to move only in the forward or backward direction.

装着して構成される。 In the figure, the tray transport vehicle of the present invention has a tray partition frame 4 erected on one side and a tray mounting table 6 having a plurality of tray partition protrusions 5 formed on the upper surface.
, wheels 2a and 2b are installed on the front, rear, left and right sides of the rectangular frame body 1, respectively.
In a tray transport vehicle mounted on a trolley 3, wheels 2a and 2b are rotatably attached to a plate 10 fixed to a frame 1 at a circular portion 8 formed on the upper surface of a wheel mounting bracket 9. At the same time,
The left and right wheels 2b are connected by a link rod 11 at a wheel mounting bracket 9, and a locking groove 12 and protrusions 13a, 13b are formed on the outer periphery of the circular portion 8 of the wheel mounting bracket 9 that is attached to one of the left and right wheels 2b. , a lever 15 is provided on the side surface of the plate 1 with a protrusion 14 that fits into and disengages from the locking groove 12, and the free end 15a is connected to a spring 16 so that the lever 15 is biased toward the circular portion 8.
The lever 15 is pivoted so as to be rotatable at 0, and a lock pin 17 for the lever 15 is mounted in a direction perpendicular to the lever 15 so as to be biased upward via a spring 17f.

されている。 In this configuration, the mechanism for rotatably attaching the left and right wheels 2b to the plate 10 via the mounting fittings 9 is similar to the known mechanism for rotatably attaching the front and rear wheels 2a to the plate 10.
This is done by mounting the circular portion 8 formed on the top surface of the mounting bracket 9 to the mounting plate 10a fixed to the back surface of the mounting bracket 9 via a bearing 10b. Also, the parts other than the mounting mechanism of the wheels 2b are the same as those of the conventional tray transport vehicle. Further, the lever 15 is pivotally supported by a support shaft 18 provided at one corner of the plate 10, and is supported by a mounting bracket 9.
It is provided in the tangential direction with respect to the circular portion 8 formed on the upper surface of. The free end 15a is a spring 16 whose one end is fixed to a support rod 19 hanging vertically from the frame 1.
The lever 15 is always biased toward the circular portion 8, and in a normal state, the protrusion 14 provided on the side surface of the lever 15 is fitted into the groove 12 provided on the outer periphery of the circular portion 8.
又、レバー１５の上面にはロツクピン１７の案
内板１５ｂが形成されている。 Further, a guide plate 15b for the lock pin 17 is formed on the upper surface of the lever 15.

付勢され常時レバー１５の上方に位置している。 The lock pin 17 is formed of a lock head 17d that passes through a tube 17a fixed to the plate 10 so as to be able to move up and down through a shaft 17b, and has a locking step 17c at the lower end of the shaft 17b located below the plate 10. At the same time, a foot plate 17e is formed at the upper end of the shaft 17b located above the plate 10, and a spring 17f is wound around the shaft 17b between the tube 17a and the foot plate 17e. Therefore, the lock head 17d is biased via the spring 17f and is always located above the lever 15.

る。(Function) Under normal conditions, the circular portion 8 formed on the upper surface of the mounting bracket 9 becomes circular by fitting into the groove 12 the protrusion 14 of the lever 15 which is biased toward the circular portion 8 by the spring 16. The portion 8 is locked, and the wheels 2b are in a state where they can only be moved in the front and rear directions, similar to the wheels of a conventional tray carrier.

れる。 Therefore, when moving the tray transport vehicle laterally, step on the foot plate 17e of the lock pin 17 to lower the lock head 17d. The lock head 17d presses the guide plate 15b of the lever 15 and moves the lever 15 as shown in FIG. Rotate it to the 15' position, then turn lever 1.
The side edge of the lock head 17d is engaged with the stepped portion 17c of the lock head 17d.
すると円形部８はレバー１５の突起１４による
ロツクが解除されて円形部８と一体の車輪２ｂは
旋回自由となり、横方向（Ｂ−B′方向）への移
動が可能となる。 Then, the circular part 8 is unlocked by the protrusion 14 of the lever 15, and the wheel 2b integral with the circular part 8 becomes free to turn, allowing movement in the lateral direction (in the direction of B-B').

の第３図に示す位置に復帰する。 When the tray transport vehicle is moved laterally, the wheels 2b change direction in the lateral direction. For example, when the tray transport vehicle is moved in the direction B, the wheels 2b turn more than 45 degrees and the wheels 2b change direction as shown in Fig. 2.
When the position b' is reached, the projections 13a, 1 of the circular part 8
3b also rotates, and one of the protrusions 13a abuts against the side surface of the lever 15, opening the lever 15 further outward from the position 15'. Then, the lock head 17d of the lock pin 17 is disengaged from the lever 15, and the lock pin 17 returns to its original position as shown in FIG. 3 by the repulsive force of the spring 17f.
なお、トレー運搬車をB′方向に移動させた場

能にロツクされる。 Furthermore, when the tray transport vehicle has completed its lateral movement, if the tray transport vehicle is moved slightly in the front-back direction and the orientation of the wheels 2b is changed in the front-rear direction (A-A' direction), the circular portion 8 is also moved by the wheels. As the wheel 2b turns, the groove 12 matches the position of the protrusion 14 of the lever 15, and the protrusion 14 is fitted into the groove 12 again by the biasing force of the spring 16, locking the wheel 2b so that it can move only in the front and rear directions. be done.

One wheel connected by a link rod is locked from turning by a lever protrusion, allowing stable operation only in the front and rear directions under normal conditions, and when moving sideways, the foot plate of the lock pin is pressed. The lock pin is automatically disengaged at the same time as the lateral movement, so after the lateral movement is completed, the carrier is moved slightly in the front and rear directions, and the wheels are turned in the front and rear directions. This has the advantage that it can be easily returned to normal by simply using the
