Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a device for fixing a tilt of a truck when a load is transferred to a bed of the truck.

[Prior Art] When an article stored in a warehouse is taken out of the warehouse and transferred to a truck, a truck loader is installed in the vicinity of the loading / unloading port of the warehouse, and the article (hereinafter, There is a technology to transfer the cargo.

The truck loader automatically transfers the load transported to the end of the in-warehouse transport conveyor to the loading platform of the truck.For example, the entire truck loader moves on a rail that is orthogonal to the transport conveyor. There is a truck loader including a roller conveyor and a load pushing device on a load table that can be raised and lowered.

[Problems to be solved by the invention]

The loading platform can be moved up and down to match the loading transfer surface with the unloading conveyor or the loading transfer surface with the loading base of the truck.

However, no matter how much the loading platform is positioned at a fixed position, the height of the loading platform of the truck differs for each truck, and the step between the loading platform and the loading platform of the truck allows the load to be carried in smoothly. There was something that couldn't happen.

[Means for solving problems]

In order to solve the above problems, the present invention provides a detachable reflector plate for a truck stopped at a luggage transfer station, forms a horizontal line on the reflector plate, and conveys the cargo on the warehouse side. A detector for detecting a horizontal line of the reflection plate on a loading platform of a truck loader that travels between an end portion and the load transfer station,
A cylinder for supporting the tilt of the truck from below is provided, and the lifting and lowering of the lift base is stopped based on the detection of the horizontal line.

[Action]

The distance between the loading level of the lift table and the detector is unchanged, and the distance between the loading level of the tilt upper surface and the horizontal line of the reflector mounted on the truck is constant.
Therefore, if the distance between them is set to be the same and the lifting of the lifting platform is stopped based on the horizontal line detection, the loading level on the track loader side and the loading level on the upper surface of the tilt plate coincide. The cylinder supports the tilt of the truck from below, and the expansion and contraction of the cylinder finely adjusts the level of the tilt and prevents a step between the two due to the sinking of the vehicle body due to loading.

Next, the tilt fixing device (24) will be described. This device (2
4) is the tilt fixing means (18) on the truck loader side
And a reflection plate (25) provided on the track side, and a tilt fixing means (18) on the track loader side.
Is a cylinder (17) (17) installed on the front surface of the lift table (10) via brackets (26) (26), and a projector (28) and a receiver (29) shown in FIG. Consisting of a detector (30) consisting of. Reflectors on track side (25)
Is a hook (31) fixed to the truck body with an upper bent portion (25a) locked. White lines (32) (33) are drawn on the surface of the truck loader (4) side. There is. The lines are horizontal lines (32) and vertical lines (33)
The surface color of the reflection plate (25) other than the line is a dark color, for example, black.

With the truck loader (4) having the above structure, the load (B) conveyed to the end of the conveyor by the conveyors (1a) to (1f) shown in FIG. 5 is tracked (6).
The operation of transferring to the loading platform will be described below.

Roller conveyors (22) (22) on the (10) ascending / descending track loader (4) from the above conveyors (1a) to (1f)
The load (B) is transferred to and the truck loader (4) travels to the load transfer station (S) while the load (B) is transferred, and stops at the station (S). After the stop, the elevator (10) is moved up and down, the height of the roller conveyors (22) (22) is set to a predetermined height, and the tilt (6a) of the truck (6) is lowered by the tilt fixing means (18). Supported by the Aori (6a)
Or downward movement due to the load amount of the truck (6) is prevented.

When the elevator table (10) is moved up and down, the detector (30) detects the horizontal line (32) of the reflection plate (25) while the elevator table (1) is moved.
0) is moved up and down, the detector (30) detects the horizontal line (32), and at the same time, the elevator (10) is stopped from moving up and down, so that the detector (30) and the reflector (25) are leveled. Set the line (32) on the same horizontal plane. Above detector (30)
The distance between the loading level (L1) of the roller conveyor (22) (22) and the loading level (L2) on the upper surface of the tilt (6a) and the reflection plate (25) are not changed. The distance is constant, and by setting the detector (30) and the reflector (25) at the same height, the roller conveyors (22) (22)
And the loading level (L1) (L2) of the tilt (6a) can be set to the same height. The level of the tilt (6a) can be finely adjusted by expanding and contracting the cylinder (17) that supports the tilt (6a) from below. Also, by detecting the vertical line (33) with the detector (30), the track (6) with respect to the track loader (4)
Can be detected in the lateral direction. The detection of the lines (32) and (33) by the detector (30) converts the amount of reflected light received by the light receiver (29) into a voltage,
2) Reflected light quantity (voltage) of the (33) part and the non-line part
Made by the difference of. After setting the loading levels (L1) and (L2) of the roller conveyors (22) (22) and the tilt (6a) to the same height by raising and lowering the lift table (10),
The roller (21) is rotationally driven to move the load (B) toward the loading platform of the truck (6), and after the movement is completed, the load (B) is pushed into the loading platform by the pusher (23). At that time, since the loading levels (L1) and (L2) of the roller conveyors (22) (22) and the tilt (6a) are the same height,
The load transfer from the truck loader (4) to the truck (6) can be smoothly carried out without any trouble.

Since the reflector (25) is detachable from the truck (6), the same reflector (25) should be locked to the same type of trucks (trucks having the same height of the loading platform) each time. Since it can also be used as a single unit, there is no need to prepare a reflector (25) for each truck, which is very economical, and at the same time, the loading level (L1) of the roller conveyors (22) (22) ), There is an advantage that the loading level (L2) of the tilt (6a) can be set immediately by replacing the reflecting plate corresponding to the change.

[Effect of device]

As described above, according to the present invention, the loading level of the roller conveyor of the truck loader and the loading level of the tilt of the truck bed can always be kept at the same height. Transfer of loads has become very smooth. Moreover, since the same reflector can be used for the same type of truck by locking each time, it is not necessary to prepare a reflector for each truck, which is very economical. Further, in order to assist the loading of the load in the truck, a roller conveyor for loading the load may be installed on the tilt of the truck.
Even in such a case, even if the loading level on the upper surface of the tilt is changed, the loading level on the truck side and the truck loader side can be immediately changed by using a reflector that has been created in consideration of this change. Is matched with.
