A loading platform vertical position regulating device (packing platform fixing device) that regulates the vertical position of the loading platform 3 so as to prevent the loading platform 3 of the truck from being lowered due to loading. The detailed structure of the platform position regulating devices 100 and 200 will be described later.

Next, a loading method using the loading device having the above-described configuration will be described with reference to an embodiment in which loads 4, 4'are left-aligned (with respect to the forward direction of the truck) and loaded on the truck bed 3. For the movement of, refer to FIG. 8 to FIG.
The movement of each part of the apparatus will be described with reference to FIGS. It should be noted that this left-side stacking is used when traveling on a general road, and is used to prevent the load from easily collapsing to the left side because the road shoulder is normally lowered to the left.

In carrying out the loading method in this embodiment, first, as a reference step, the truck is landed (stopped) from the rear of the truck just before the loading apparatus 2. This landing does not need to be performed accurately by making the centers of the truck and the loading device 2 coincide with each other, and within the width W1 of the left and right loads 4, 4'transported on the load transport conveyors 1, 1 '. The truck bed 3 (width W2 <W1) may be inserted. Then, as described above, the reflection plate 31 is moved from the detectors 83, 83 for detecting the vertical position of the loading platform 3 to the loading conveyors 6, 6 '.
Mounted below the roller conveyor 34 of the truck bed 3 by a distance equal to the distance up to and below the inner left wall of the truck. And again, guide brackets 81, 81 'to the slide shaft 8 in the loading device 2
Is set to be equal to the width W3 (<W2) of the loads 4 and 4'which are left-justified and loaded on the loading platform 3 of the truck. The distance W4 (see FIG. 1) between the side pushers 71, 71 'of the width-shifting devices 7, 7'at this reference stage has a relationship of W4> W1.

When the start button (not shown) of the loading device 2 is pressed after the above-described loading preparation is completed, the slide shaft 8 attached to the loading device 2 is moved to the right from the left end origin by the slide motor 53, and slides. When either one of the detectors 82, 82 for detecting the horizontal position of the loading platform 3 attached to the shaft 8 detects the reflective plate 31 of the truck, the slide motor 53 stops and the slide shaft 8 also stops. That is,
A loading platform detection step is performed in which the detectors 82, 82 move in a direction substantially perpendicular to the carrying-out direction of the loads 4, 4'to detect the loading platform position.

Then, the drive motors 63, 6 of the loading conveyors 6, 6 '
3'is driven, and 2 from the conveyors 1 and 1 ', respectively.
A total of four loads 4, 4, 4 ', 4', one by one, are loaded onto the loading conveyor 6, 6 '. Left and right loads 4, which were carried in
4'has the same width W1 as that of the load carrying conveyors 1, 1 '. This loading is detected by the load detectors 91, 92, 91 ', 92' on the loading conveyors 6, 6 '.

4 loads 4, 4, 4'on the loading conveyor 6, 6 ',
4'is loaded, the side pusher driving parts 74, 74 'of the width-shifting devices 7, 7'are driven, whereby the side pushers 71, 71' are loaded.
Align the widths of 4, 4'and 4'from both sides. The width adjustment by the side pushers 71, 71 'is performed by the detectors 75, 76 attached to the side pushers 71, 71' with the guide brackets 81, 81 'attached to the slide shaft 8 stopped at the predetermined positions as described above. It is completed by stopping the side pusher driving units 74 and 74 ′ when “′” is detected. That is, a detector 75 in which the bed position detected in the bed detection step is attached to the pulling device 7, 7 ',
By performing the width-shifting position detecting step of detecting the width-shifting completion position of the loads 4, 4, 4 ', 4'detected by 76', the width-shifting of the loads 4, 4, 4 ', 4'is completed. At this time, the guide brackets 81, 81 'attached to the slide shaft 8
As described above, the interval is equal to the width W3 of the truck which is left-justified to be loaded on the bed 3, and the left guide bracket 81 connects the left inner wall surface of the truck and the left side surface of the load. Since the slide shaft 8 has stopped moving so that the left and right loads 4 and 4'are located at positions where they can coincide with each other, the widths of the left and right loads 4, 4'are left-aligned with the loading platform 3 of the truck for loading W3.
The width of the load 4 is equal to
The left side surface of the track substantially coincides with the left inner wall surface of the truck. That is, the pushed loads 4, 4, 4 ', and 4'are in positions where they are left-justified and loaded on the truck bed 3 as they are if they are pushed toward the truck bed 3. Further, at the time of this width adjustment, the loading conveyors 6 and 6 ′ are
Together with 4, 4 ', 4', the width is adjusted to the inside, and when the width adjustment is completed, it is stopped and fixed by the brakes 62, 62 '.
In addition, when trying to load the load to the loading platform 3 of the truck by loading it to the left, the left side pusher 71 may be hardly driven when the truck is completely landed on the left side of the loading device 2.

Further, at the same time as the width adjustment as described above, the loading conveyor 6,
Leveling of the upper surface of 6'and the upper surface of the lift roller conveyor 34 of the truck bed 3 is also performed. That is,
By driving the lifting cylinder 52 of the lifting device 5, the lifting unit 5
1 rises, the slide shaft 8 attached to the elevating part 51 rises, and both detectors 83, 83 for detecting the vertical position of the loading platform 3 attached to the slide shaft 8 detect the reflection plate 31. Thus, the lifting cylinder 52 is stopped and the level adjustment is performed.

When the above-mentioned width adjustment and leveling are completed, the loading conveyors 6 and 6'are driven again, and the loads 4, 4, 4 ',
4'is a lift roller conveyor 34 of the truck bed 3.
When the rear two left and right loads 4, 4'pass over the load detectors 92, 92 'in front of the loading conveyors 6, 6' (on the side of the truck bed 3), the pushing pushers 9, 9 ''Actuates to push the loads 4, 4, 4', 4'to ensure that they are transferred onto the lift roller conveyor 34 of the truck bed 3 to complete loading.

When the loading is completed, the pushing pushers 9, 9'return to their original positions, the brakes 62, 62 'of the loading conveyors 6, 6'are released, and the side pushers 71, 7' When 71 'returns to its original position, the loading conveyors 6 and 6'return to their original positions via the return hooks 77 and 77', and the elevating section 51 of the elevating device 5 descends and is placed there. The upper surfaces of the loading conveyors 6 and 6'are equal to the upper surfaces of the load carrying conveyors 1 and 1'to prepare for the next loading.

Then, using the above-mentioned loading device, as shown in FIG. 11, in order to load the loads on both sides of the truck by loading them on the loading platform 3 of the truck, guide brackets 81, 81 'to the slide shaft 8 are used.
Has a mounting interval of W3, and the width W5 of the left and right loads 4, 4'which are loaded on the loading platform 3 of the truck by being moved to both sides.
Since the detector 75 'is attached to the inside of the detector 76' by a distance corresponding to the difference (W5-W3) from (<W2), the detectors 75 and 75 'may be used for width adjustment. . Such a loading mode is suitable when traveling on a winding road such as a mountain pass.

As is apparent from the description of the above-described embodiment, the loading device having the above-described configuration allows the detector 82 of the slide shaft 8 to horizontally move the truck bed 3 even if the landing position of the truck is not always accurate. Since the directional position can be detected and the loads 4 and 4'can be directly moved to a predetermined position based on the detected position, if the detector 82 detects the width-adjusted position once at the start of loading, the load can be set after the start of loading. Repeated automatic loading can be done without this detection, it is not necessary to move the device body after moving it to the center of the device body as in the conventional device, and every time the device body is loaded. It has the advantage that it does not need to be moved. Moreover, since the vertical level adjustment can be performed at the same time as the horizontal width adjustment, there is no wasteful operation, which is highly efficient and simple. Further, since the loading conveyors 6 and 6'are designed to move together with the width-shifting devices 7 and 7 ', the loading conveyors 6 and 6'
It is not necessary to install a conveyor orthogonal to 6 ', and by moving the loading conveyors 6 and 6'in this way, the load pusher 9, 9'disposed on the loading conveyors 6 and 6'provides a load 4 There is also an advantage that the central portion of 4'can be easily pushed in without requiring any special device.

The case where the lifting device 5 is fixed at a predetermined position has been described above. However, in the practice of the present invention, the lifting device of the loading device moves horizontally on the fixed path 11 as shown in FIG. The structure may be such that it is disposed on the trolley 12 that can be used. By configuring the loading apparatus in this way, three trucks, which have been loaded on the floor after receiving a load from any one of, for example, three sets of the conveyors 1 and 1'for load transportation shown in FIG. It is possible to load a load on any one of the loading platforms 3 of the above. In addition, in FIG.
Reference numeral 13 is a limit switch for stopping the carriage 12 in front of the load carrying conveyors 1, 1'of each set.

The setting state of the arm frame 104 in the storage section 113 is detected by the fall bracket 116 fixed to the arm frame 104 activating the fall detector (limit switch) 117 fixed to the support frame 101. .

That is, when loading the cargo bed conveyors 1 and 1'and the loading device 2 on the cargo bed 3 of the lift roller conveyor-equipped truck, the cargo bed front-rear position restricting apparatus 100 operates the operation button for switching to the truck mode. Motor 1 by operation
By driving 09, the armor frame 104 is set in the work area as shown by the solid lines in FIGS. 13 and 14 (track mode). On the other hand, in the case of loading using a forklift, the arm 109 frame 104 is driven by driving the motor 109 by operating the switching operation button to the fork mode.
13 and 14, as indicated by the chain double-dashed line in FIG.
Set to 13 (fork mode).

Therefore, according to the front and rear position regulating device 100 of the loading platform, in the truck mode, a rear loadable truck having the auxiliary bumper 3A attached thereto invades at the back to land on the floor as shown in FIGS. At this time, the arm frame 104 of the luggage rack front-back position regulating device 100 is in a horizontal state,
When the auxiliary bumper 3A pushes the landing bracket 106 urged by the spring 107, the landing detector 108 is activated, and a landing completion lamp (not shown) is turned on to support the truck driver to stop the landing completion. . The shock-absorbing portion 105 attached to the arm frame 104 receives the impact force exerted by the auxiliary bumper 3A. Thereby, the loading platform front-back position regulating device 100 protects the loading device 2 and
An appropriate stop position in the front-rear direction of the loading platform 3 is secured.

Further, according to the loading platform front-rear position restricting device 100, in the fork mode, the arm frame 104 is housed in the storage section 113 sandwiched between the support frames 101, so that the arm frame 104 with respect to the floor berth of the truck.
The occupancy state is reduced as compared with the truck mode, and it is possible to form a wide traveling space for the forklift.

In the above-described loading platform front-rear position restricting device 100, when the arm frame 104 is set in a work area where the arm frame 104 is in a horizontal state, the rotating shaft 103 integrated with the arm frame 104 is supported by the bearing 102 on the support frame 101. The driven sprocket 11 attached to one end of the rotating shaft 103.
1 is connected to a drive sprocket 110 of a motor 109 via a chain 112. The motor 109 has a built-in brake, and in this stopped state, the arm frame 104 maintains a horizontal state. The load applied to the chain 112 is only the own weight of the arm frame 104 and the like, and no great force is applied to the chain 112. Further, when the truck lands on the floor, a horizontal collision with the arm frame 104 occurs.
The bearing 102 and the support frame 10 are provided via the rotating shaft 103.
Therefore, the load is hardly applied to the driven sprocket 111 and the chain 112. The bearing 102 is installed at the same level as the auxiliary bumper 3A of the truck. Therefore, the motor 109, the drive sprocket 110, the driven sprocket 111, and the chain 112 need only have an output and strength enough to swing and fix the arm frame 104 and the like, and have a small capacity and a small size.

The loading platform vertical position regulating device 200 is shown in FIG. 1, FIG. 2, and FIG.
As shown in the figure, it is arranged at a position immediately before the truck landing berth side of the loading device 2, and is formed as shown in FIGS. 15 and 17.

That is, the loading platform up-and-down position regulation device 200 is the loading device 2
A pit-shaped storage portion 201 is formed on the floor surface immediately before the truck landing berth side, support frames 202 are fixedly installed on both sides of the bottom portion of the storage portion 201, and a bearing 203 fixed to the upper portion of each support frame 202. The rotary shaft 204 is rotatably supported by the rotary shaft 204, and a pair of left and right hydraulic cylinders (load platform position restricting parts) 205 are fixed to both ends of the rotary shaft 204. Both hydraulic cylinders 205 have their cylinder mounting portions 206 fixed to the rotary shaft 204 by fixing bolts 207. A platform support 208 is provided on the upper end of the piston rod of the hydraulic cylinder 205, and a platform detection bracket 209 is provided. The loading platform detection bracket 209 is elastically urged upward in FIG. 16 by the spring 210, and is lowered downward by the load exerted by the auxiliary bumper 3A of the truck, and the lower end flange portion 209 thereof.
By A, the detector (limit switch) 211 provided on the main body of the hydraulic cylinder 205 can be operated. 212 and 213 are hydraulic hoses. The loading platform vertical position restricting device 200 includes a lower limit detection bracket 214 provided at the upper end of the piston rod of the hydraulic cylinder 205.
However, the contracted state can be detected by operating the lower limit detector (limit switch) 215 provided in the main body of the hydraulic cylinder 205.

Further, in the loading platform vertical position restricting device 200, a motor (drive unit) 216 with a brake and a speed reducer is fixedly installed on one of the support frames 202, and a drive sprocket 217 fixed to the output shaft of the motor 216 and a rotating shaft 204. The chain 2 to the driven sprocket 218 fixed to one end of the
It is wound around 19.

As a result, the loading platform up-and-down position regulating device 200 drives the motor 216 to move the hydraulic cylinder 205 to the rotary shaft 2.
04, and the hydraulic cylinder 205 is set to the work area for position control shown by the solid lines in FIGS. 15 to 17, and the storage unit 2 is shown as shown by the chain double-dashed line in FIG.
It is possible to selectively set any of the states set to 01. The setting state of the hydraulic cylinder 205 in the working area is detected by operating the upright detector (limit switch) 221 fixed to the support frame 202 by the upright detection bracket 220 fixed to the rotating shaft 204. , This detector result displays a landing ready lamp (not shown). Storage 201 of hydraulic cylinder 205
The fall detection bracket 222 fixed to the rotary shaft 204 operates the fall detector (limit switch) 223 fixed to the support frame 202.

That is, when the cargo bed vertical position restricting apparatus 200 loads the cargo cylinders 1 and 1 ′ and the loading apparatus 2 onto the cargo bed 3 of the truck equipped with the lift roller conveyor, the hydraulic cylinder 205 is used in FIG. The work area is set as shown by the solid line in FIG. 17 (track mode). On the other hand,
When loading using a forklift, the hydraulic cylinder 205 is set in the storage unit 201 as shown by the chain double-dashed line in FIG. 15 (fork mode).

Therefore, according to the bed top / bottom position restricting device 200, in the truck mode, the rear loadable truck to which the auxiliary bumper 3A is attached is installed in the buffer section 105 attached to the arm frame 104 of the bed front / rear position restricting device 100. After touching and landing, the loading platform support portion 208 of the hydraulic cylinder 205 can be raised by pressing a raising operation button (not shown). In the luggage carrier support portion 208, the luggage carrier detection bracket 209 that has been elastically springed in advance by the spring 210 comes into contact with the auxiliary bumper 3A, and the collar portion 2 thereof is
09A stops the rise by operating the detector 211 (fixing of the bed is completed). When the truck is empty, the truck level is high because it is raised, and when the truck is loaded, the truck sinks and becomes lower, but the truck is fixed at a high level. Therefore, the loading device 2 can stably perform the loading operation without always detecting the vertical movement of the loading platform 3. After the loading device 2 completes the loading, by pressing a lowering operation button (not shown), the platform support 208 is lowered, and the lower limit detection bracket 214 operates the lower limit detector 215 to lower the platform support 208. Stops.
This allows the truck to start.

In addition, according to the loading platform up-and-down position regulating device 200, in the fork mode, the hydraulic cylinder 205 falls over by pressing an unillustrated inversion button. However, the hydraulic cylinder 205 is allowed to fall down only when the lower limit detector 215 detects the contracted state of the pistol rod. The overturning of the hydraulic cylinder 205 is performed by the rotation of the motor 216, and the driving force is the driving sprocket 217.
Is transmitted to the driven sprocket 218 through the chain 219, and the rotation shaft 204 is rotated. When the fall detector 223 detects the fall detection bracket 222, the operation of the motor 216 is stopped (fall complete). When the hydraulic cylinder 205 is completely fallen, the hydraulic cylinder 205 is stored in the storage portion 201. Therefore, if the upper portion of the storage portion 201 is covered, the forklift can travel on the floor. This eliminates the occupancy state of the loading platform up-and-down position regulation device 200 with respect to the floor berth of the truck, and makes it possible to form a wide traveling space for the forklift.

In the loading platform up-and-down regulating device 200, when the hydraulic cylinder 205 is upright and supports the auxiliary bumper 3A of the truck, the load is the hydraulic cylinder 20.
Since it is received by the rotary shaft 204 and the bearing 203 via 5,

The 9 has almost no load. That is, the motor 2
16, drive sprocket 217, driven sprocket 21
8. The chain 219 is sufficient if it has an output and strength sufficient to make the hydraulic cylinder 205 fall down or stand upright, and it has a small capacity and a small size.

In addition, in the embodiment of FIGS. 1 to 17 described above, the armor frame 104 of the cargo bed front-rear position regulating device 100 is attached to the storage unit 1.
13 in the fork mode in which the hydraulic cylinder 205 of the cargo bed vertical position regulating device 200 is housed in the storage portion 201, if the loads 4, 4'are moved close to each other, it will be difficult to pick them up by the forklift, so the width adjustment devices 7, 7 '. Is not used. Also, in this fork mode, the loading device 2
Is the load 4, 4'that has reached the tip of the loading conveyor 6, 6 '.
It is equipped with a forklift work control circuit that can take out one pallet at a time and forward one pallet at a time. In this fork mode, the lifting device 5 is not operated, and the loading conveyors 6 and 6'of the loading device 2 may be held at the level of the load carrying conveyors 1 and 1 '.

Further, in the embodiment shown in FIGS. 1 to 17, the hydraulic cylinder 205 is fixed to the rotary shaft 204 at its end portion, but the hydraulic cylinder 205 is fixed to the rotary shaft 204 at its intermediate portion. It may be one.
