DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment according to the present invention will be described with reference to FIGS. The present embodiment relates to a tire loading device 10 and a tire unloading device 40 to the tire uniformity measuring device 2 and the tire balancer measuring device 3.

FIG. 1 is an overall plan view, and FIG. 2 is a side view thereof. The tire loading device 10 includes a trolley 11 and a lifting device
The truck 11 has a roller conveyor 14 arranged on a frame 13 supported by wheels 12, and a handle 15 is protruded from an end of the frame 13.

The roller conveyor 14 has a drive roller rotated by a motor disposed between idle rollers, and can transport the tire 1 on the roller. On the roller conveyor 14, a set of stacked tires
Can be installed simultaneously in pairs.

FIG. 2 shows a state in which a set of five tires 1 stacked on each other is mounted on a three-set roller conveyor 14. When the roller conveyor 14 is driven in this state, three sets of tires move at the same time, and can be sequentially transferred from the front set.

The truck 11 travels with the tires mounted thereon, and abuts its front end at a predetermined position of the lifting / lowering device 21 to transfer the tires 1 in each stacked set. The elevating device 21 has a vertically long frame.
An elevating roller conveyor 23, which is a support plate of a tire having a driving roller disposed on a frame 22, is supported up and down freely, and the elevating roller conveyor 23 is moved up and down by an elevating drive mechanism.

Rollers 29 are vertically arranged on the back side of the frame 22. The rollers 29 abut on the outer peripheral surface of the stacked tires transferred to the elevating roller conveyor 23 to position and stack the tires. It is possible to smoothly raise the tire.

An extruding projection 28 is supported on the upper part of the frame 22 by a supporting member 26 which is moved up and down by an elevating motor 25. The extruding projection 28 protrudes downward. It is designed to move horizontally. The connecting conveyor 30 is positioned at a predetermined height of the frame 22 from the front.
Swings and is hanged slightly inclining, and a carry-in conveyor 2a of the uniformity device 2 is connected to the connecting conveyor 30.

A trolley 11 on which three sets of stacked tires are mounted
Is brought into contact with a predetermined position of the elevating device 21, the roller conveyor 14 of the carriage 11 and the elevating roller conveyor 23 of the elevating device constitute the same horizontal plane. It is smoothly transferred to the set elevating roller conveyor 23.

The transferred stacked tires are moved up and down by a driving mechanism.
The roller 24 is raised slightly together with the lifting roller conveyor 23 so that the lower surface of the uppermost tire 1 is set at the height of the connecting portion of the connecting conveyor 30.

The extrusion protrusion 28 above the frame 22 is lowered from the home position shown by the solid line in FIG. 3 and inserted into the inner hollow portion of the uppermost tire 1 and then moved forward to move the uppermost protrusion 1 Push tire 1 forward. The tire 1 moves on the inclined connecting conveyor 30 to the carry-in conveyor 2a, and is supplied to the uniformity device 2 by the carry-in conveyor 2a.

After the tire 1 is extruded, the extrusion protrusion 28
Retreats and waits. When the lifting roller conveyor 23 rises by one tire in a state where the remaining four tires 1 are stacked and supported, the extrusion protrusion 28 enters into the inner hollow portion of the tire 1 at the newly uppermost stage. Therefore, when the pushing projection 28 moves forward again, the next tire 1 can be pushed forward and carried into the uniformity measuring device 2.

By repeating the retreating of the extrusion protrusions 28, the raising of the lifting roller conveyor 23, and the advancement of the extrusion protrusions 28, the stacked tires 1 are carried in one by one from the upper stage.

When the lowermost tire 1 has been carried in, the extrusion protrusion 28 returns to the home position, the elevating roller conveyor 23 descends and is positioned at the same height as the roller conveyor 14 of the carriage 11, and the driving roller is rotated by the rotation of the driving roller. The second set of stacked tires is transferred from the cart 11 to the elevating roller conveyor 23 of the elevating device 21.

Thereafter, the tires of the second set are sequentially loaded into the uniformity measuring device 2 in the same manner as in the case of the first set of stacked tires. Thus, the loading of the tires 1 one by one into the uniformity measuring device 2 can be performed automatically without bothering the operator.

The tire 1 for which the uniformity measurement has been completed by the uniformity measuring device 2 is discharged to the connecting conveyor 31, conveyed, and supplied to the balancer measuring device 3. Tire 1 for which balancer measurement has been completed by balancer measuring device 3
Is sent out to the tire unloading device 40.

The tire unloading device 40 comprises a stacking device 41 and a unloading conveyor 51. The stacking device 41 includes a lifting drive mechanism.
A lifting roller conveyor 43 that moves up and down by 42 is disposed along the discharge side of the balancer measuring device 3. The lifting roller conveyor 43 includes a plurality of rollers including a driving roller, and is capable of transporting the tire 1 in a direction perpendicular to the tire discharging direction of the balancer measuring device 3.

A support stand 45 is provided upright on the opposite side of the balancer measuring device 3 with the lifting roller conveyor 43 interposed therebetween.
A pair of left and right guide rails oriented in the front and rear direction at the top of 45
46, 46 are laid, and a sliding roller board 47 is erected on the guide rails 46, 46 so that both side edges are slidable.

The sliding roller board 47 has a plurality of rollers 47b arranged in a rectangular frame 47a. Cylinders 48, 48 are attached to the outside of the left and right guide rails 46, 46, respectively.
The tip of 48 a is fixed to the underframe 47 a of the sliding roller board 47.

The cylinders 48, 48 are driven to drive a cylinder rod.
When 48a and 48a are extended, the sliding roller board 47 protrudes toward the balancer measuring device 3 side, and can receive and support the tire 1 discharged from the balancer measuring device 3 just above the elevating roller conveyor 43.

The balancer measuring device 3 for the guide rails 46, 46
Bracket on the cross member 49 installed between the side ends
A roller-shaped stopper 51 is provided at an end of the bracket 50 protruding toward the balancer measuring device 3.

Therefore, as shown in FIGS. 2 and 5, when the tire 1 is discharged from the balancer measuring device 3 to the sliding roller board 47 with the sliding roller board 47 protruding above the elevating roller conveyor 43, The tire 1 moves on the roller 47a, and the outer peripheral surface thereof comes into contact with the stopper 51, and is placed at a predetermined position on the sliding roller board 47.

In this state, when the cylinders 48, 48 are driven to retract the sliding roller disc 47, the sliding roller disc 47 supported from below moves, leaving the tire 1 stopped by the stopper 51. Therefore, the tire 1 falls downward in a horizontal posture.

Before the tire 1 falls, if the lower elevating roller conveyor 43 is appropriately raised in advance and waits just below the tire 1 as shown by a two-dot chain line in FIG. Falls onto the elevating roller conveyor 43 at a short falling distance, so that it is securely placed at a predetermined position.

Then, the elevator roller conveyor 43 on which one tire 1 is mounted is lowered by one tire and waits, and the sliding roller board 47 is projected to wait for the next tire 1 to be discharged. When the tire 1 is discharged, it comes into contact with the stopper 51 and slides on the sliding roller disc.
Since the tire 1 is placed on the predetermined position of the tire 47, if the sliding roller disc 47 is retracted again, the tire 1 is dropped and stacked on the tire 1 on the lifting roller conveyor 43 this time.

By repeating the above steps, the tires 1 are sequentially stacked on the elevating roller conveyor 43 and are stacked. When the five tires 1 are stacked, the driving rollers of the lifting roller conveyor 43 are driven to move the five stacked tires to the carry-out conveyor 55, and are moved and carried out by the carry-out conveyor 55.

The unloading conveyor 55 is a slightly inclined roller conveyor, and the tires stacked on one another move by their own weight and are stopped at the downstream end. The stacked tires carried out to the downstream end are moved to the cart 60 and carried.

The push cart 60 has a pair of left and right support arms 62 at the lower end of a vertically long backrest 61 as shown by a two-dot chain line in FIG.
Are provided at right angles, a wheel 63 is provided at a base end portion of the support arm 62, and a handle 65 and an auxiliary wheel 64 are provided at the rear of the backrest 61 so as to project up and down, respectively.

The hand cart 60 can swing about the wheels 63, and the pair of left and right support arms 62 are inserted into both sides of the lower surface of the stepped tire stopped at the downstream end of the carry-out conveyor 55 so as to move toward the support arm 62 side. After being transferred, the push cart 60 is swung to allow the stacked tires to lean against the backrest 61 and to be transported while being supported by the wheels 63 and the auxiliary wheels 64.

As described above, the tire 1 discharged from the balancer measuring device 3 falls while being supported and positioned by the temporary sliding roller disc 47 and is supported by the elevating roller conveyor 43. The sheets are sequentially stacked on top of each other, and are discharged in a stacked state. During this time, all operations are performed automatically, and the labor is greatly reduced without bothering the operator.
