Abstract

PROBLEM TO BE SOLVED: To safely move and array a bank by a relatively simple, inexpensive apparatus by mounting a pressing mechanism to a carrying apparatus main body upward and downward and pressing a bank base at a fall position. SOLUTION: When a bank 1 is carried up to a roller conveyor 2 downward of a main body 10, a motor 22 of a pressing mechanism 20 is actuated, a rectangular column 21 is lowered to the lower limit, and a channel member 24 of a lower end covers a roller conveyor 2. Then, a main body driving motor 14 is started up, and the main body 10 forwards while pushing the channel member 3 for loading the bank 1. When the channel member 3 loading the bank 1 abuts against the channel member 3 loading the bank 1 stopped forward, large force is applied to the channel member 24. Since an air cylinder pressure of a sensor 30 rises, when its air pressure reaches a desired value, the main body driving motor 14 stops, and carries the bank to a predetermined position.

FIG. 5 is a side view showing the transfer device with a part cut away, and FIG.
FIG. 6 is a plan view for explaining a mounting state of the sensor in the transport device, and FIG. 6 is a view taken along the line BB of FIG.

In FIG. 1 to FIG. 6, four serial roller conveyors 2 are horizontally arranged side by side, and a channel member 3 having a U-shaped cross section is placed on each roller conveyor so as to cover each roller conveyor. Is placed. Bank 1
The ALC group 1a is stacked horizontally and is placed directly on the channel member 3 or via a plate member between the channel members. The main body 10 of the transfer device is of a portal type and includes two vertical side plates 11 on both sides in the width direction and a gantry 12 at an upper end, and the gantry 12 connects the side plates 11 on both sides at both ends.

A deceleration motor (drive motor) 14, which is a reversible motor, is disposed on the gantry 12, and the rotation shaft of the drive motor 14 is connected to a front portion and a rear portion of the upper portion of the gantry via a pair of chains 14b. It is connected to the two arranged counter shafts 14a. A chain wheel 15a is attached to both ends of each counter shaft 14a, while a lower chain wheel 15b is attached to a front portion and a rear portion of the lower end of the side plate 11 at a vertically corresponding position of the upper chain wheel 15a. Have been. A chain 16 is hung on the upper chain wheel 15a and the lower chain wheel 15b. At the lower end of the side plate 11, two pairs (one pair on one side) of wheels 13 mounted on the traveling rail 4 are pivotally supported, and each wheel 13 is connected to a lower chain wheel 15b.
b. Therefore, the forward and reverse rotational movement of the drive motor 14
b, counter shaft 14a, upper chain wheel 15
a, a chain 16 and a lower chain wheel 15b.
, And can reciprocate along the two traveling rails 4.

As is apparent from FIG.
Are arranged outside the roller conveyor 2, so that the gate-shaped main body 10 traveling on the traveling rail 4 is in a state of straddling the bank 1 traveling on the roller conveyor 2.

Next, the bank movable mechanism 20 attached to the main body 10 will be described. The bank movable mechanism 20 includes a horizontally long rectangular column 21 extending between the side plates 11 on both sides and capable of ascending and descending. 2 attached to the lower end of
And a pair of channel members 24. As will be described in detail later, each channel member 24 is fixed to the square pillar 21 at a position where the channel member 24 covers each roller conveyor 2 at the lowered position, and therefore, can contact each channel member 3. The channel member 3 can be pushed.

At both ends of the quadrangular prism 21, there are provided end portions 21a having a quadrangular cross section projecting outward, while a vertical slit 11a is formed in the side plate 11 (FIG. 3). Each end portion 21a of the square pole 21 is respectively
It is inserted in the slit 11a of each side plate 11 on both sides and can be guided in the vertical direction, but the movement in the front-rear direction is restricted. Both ends of the square pillar 21 are suspended by a chain 23, and the chain 23 is a chain wheel 22.
a. Then, the chain wheel 22a
Is a pair of deceleration reversible motors 22 arranged on the gantry 12
(FIGS. 1 and 2). Therefore, the rotation of the rotation shaft of the motor 22 causes the chain wheel 22 a to rotate in either direction, and the square pole 21 is raised or lowered according to the rotation direction of the motor 22.

A pair of horizontal shafts 26 (only one of which is shown in FIG. 5) is slidably inserted through the center of the square pole 21. These shafts 26
A box-shaped base 25 (FIGS. 3, 4, and 5) is suspended on the base. Therefore, the base 25 can be moved back and forth within a certain range with respect to the square pole 21. Base 25
A pair of channel members 24 that cover the roller conveyor 2 when lowered are fixed to the lower end of the roller member 2.
When the quadrangular prism 21 is raised to the upper limit, the lower end of the channel member 24 is at a position higher than the top of the bank 1, so that there is no problem when the main body 10 retreats.

On the base 25 of the bank movable mechanism 20, a pair of sensors (pressure sensors) 30 are arranged. Each of these sensors 30 has a coiled spring 31
, An air cylinder 32 and a box-shaped case 33.
The case 33 has an opening facing the side surface of the square pole 21 and is fixed to the side surface of the square pillar 21. The bases of the air cylinder 32 and the spring 31 are fixed to the bottom of the case 33, and the tops of both are connected to the base 25. Further, since the spring 31 constantly urges the base 25 forward with respect to the square pillar 21, the channel member 24 fixed to the base and the air cylinder 3 are fixed.
The second piston is in a state of protruding forward.

For this reason, the air pressure of the air cylinder 32 is normally kept low, but when the channel member 24 is pressed backward by a strong force, the piston of the air cylinder is opposed to the acting force of the spring 31. The air cylinder 32 is pushed rearward, and the air pressure of the air cylinder 32 increases. This rising air pressure is detected, and when the desired pressure is reached, the motor 14 is stopped to stop the movement of the transfer device. The biasing force of the spring 31 is adjustable,
The air pressure of the air cylinder 32 for stopping the motor 14 can also be freely set.

Next, the operation of the transfer device of the present invention will be described. Initially, the main body 10 is at a predetermined position, which is the starting position of transport, and the pressing mechanism 20 is waiting at the raised position.
In this state, when the bank 1 is transported onto the roller conveyor 2 below the main body 10, the motor 22 of the pressing mechanism 20 is operated, and the square pillar 21 is lowered to the lower limit, and the channel member 24 at the lower end is Covers the roller conveyor 2.
FIG. 4 shows this state. Then, the drive motor 14 of the main body
Is started, and the main body 24 advances while pushing the channel member 3 on which the bank 1 is mounted. At this time, since pressure is applied to the channel 24, the air cylinder 3
2, the pressure is adjusted so that the driving of the main body is not stopped at such a pressure increase.

The channel member 3 on which the bank 1 is mounted moves forward, and the channel member 3 on which the bank 1 is stopped or the stopper is fixed (see FIG. 7).
A large force is applied to the channel 24, and the pressure of the air cylinder 32 of the sensor 30 increases. When the air pressure reaches a desired value, the motor drive motor 14 of the main body stops and the bank Can be transported to a predetermined position.

Thereafter, the drive motor 14 and the motor 22 of the pressing mechanism 20 are sequentially operated in the opposite directions to slightly retreat the main body 10, raise the square pole 21 to the upper limit, and retreat the main body 10 to the original position. Let me wait.

Since the spring 31 is disposed between the pressing mechanism 20 and the sensor 30, the pressing mechanism 2
To alleviate the impact when the zero channel member 24 moves in contact with the channel 3 on which the bank 1 is mounted, or when the channel member 24 in front comes into contact with the channel member 3 on which the bank stopped is mounted. Can be.

Next, another sensor which is preferably used together with the sensor 30 will be described with reference to FIGS. FIG.
8 is a schematic side view for explaining a sensor, and FIG.
FIG. 3 is a schematic plan view for explaining a sensor.

7 and 8, a channel member 3 is covered on the roller conveyor 2, and a bank 1 to be conveyed is placed on the channel member 3. A fixed stop 40 is arranged at the foremost position where the bank 1 of the roller conveyor 2 should be stopped. Proximity switch (sensor) 42 is located in front of its fixed stop 40, e.g.
It is provided between the fourth roller and the fourth roller.
These sensors 42 are provided for each roller conveyor 2 and operate independently. The sensor 42 is, for example, a proximity switch that detects the approach of the metal when the channel member 3 is made of a metal such as iron.

As shown in FIG. 8, bank 1 is
Is placed on the two outermost roller conveyors or is placed on the inner two roller conveyors depending on the length of the plate material. Therefore, by providing the sensor 42 for each roller conveyor, detection can be performed in any case. As a result, the apparatus main body 10 can be stopped when one sensor detects it. By providing these sensors 42, for example, the bank 1 at the forefront can be stopped before coming into contact with the fixing step 40.
