(Prior Art) As shown in Japanese Unexamined Patent Publication No. 59-163237, the applicant has previously disclosed that the goods (corrugated pole boxes, etc.) shipped by factories, etc.
We have proposed a cargo transport device that accepts cargo into a loading section and sequentially loads it into a vehicle cargo box using a loading device that can be driven into a vehicle cargo box. (Problems to be Solved by the Present Invention) The above-mentioned baggage conveyance device has a problem in that work efficiency is low because the loading device operates discontinuously. That is, the cargo conveyed on the conveyor is first positioned on the dividing conveyor and then supplied to the alignment conveyor, where the cargo is aligned. Thereafter, the cargo pushed onto the stowage conveyor is moved to the planting position in the left and right direction via the stowage conveyor, and then is supplied to the cargo box by retreating while operating the planting conveyor. When cargo is being moved between conveyors, the rear conveyor must be on standby, and the loading conveyor must be moved left and right to the loading position each time, making the work complicated. The present invention has been made in view of the above points, and it is an object of the present invention to provide a cargo loading device that can continuously load cargo. (Means for solving the problem) A traveling trolley that can travel inside a cargo box, and a stowage that is movable up and down and has a width approximately equal to the width of the cargo box in front of the running trolley. and an inclined conveyor connected to the planting device. a plurality of pushers that can freely move in and out of the surface and move forward and backward in a direction perpendicular to the direction in which the goods are conveyed by the cross-feeding conveyor; It has a configuration including a plurality of loading forks that can move forward and backward. (Function) The cargo carried onto the stowage device from the inclined conveyor is
First, the items are sequentially transferred one by one to one side of the stacking device by a traverse conveyor. When the loads are lined up horizontally on the traverse conveyor, the boot 7 is positioned at the rear of the load and the main body of the boot 7 is raised to protrude from between the traverse rollers. Thereafter, when the pusher main body and the loading fork main body are moved forward at the same time, the cargo is pushed out from above the traverse conveyor by the pusher main body and placed on the loading fork main body that has moved forward in synchronism. In this state, the cargo is placed on the loading fork main body with its back surface in contact with the pusher main body located forward of the traverse conveyor. Then, when the loading fork body is moved backward, the cargo is placed on the floor of the cargo box or on the previously loaded cargo. Next, when the pusher body is retreated and lowered, it returns to the stowage work position.

The operating limits of the sliders 44, 44a and 5L are regulated by the stroke of the air cylinder 41. The links 47, 47a are formed such that the front link 47 has a shorter link length than the rear link 47a, and when the air cylinder 41 is extended, the rollers 48... The conveyance surface is the horizontal feed roller 29
It rises above the conveyance surface of a and slopes downward in the front. In addition, a lift stopper 52 is arranged on the frame 30a and integral part 30b of the loading device 30,
This is to prevent the cargo 1 from falling off from the stowage device 30 when the cargo 1 is transported forward by the upward movement of the direction changing device 40. This lift stopper 52 is composed of a stopper body 53 that is fitted to the above-mentioned bumper plate 30b so as to be able to rise and fall freely, and an air cylinder 54 that moves the stopper body 53 up and down with respect to the bumper plate 30b, and a piston of this air cylinder 54. A rod is connected to the stopper body 53. The stopper main body 53 and the air cylinder 54 are arranged so as to be slightly inclined forward in response to the fact that the direction changing device 40 is inclined forwardly and downwardly when the direction changing device 40 is raised. On the other hand, in order to detect the elevation state of the stopper body 53, a proximity switch LSI is disposed at the lower part of the stopper body 53 facing the lower surface of the stopper body 53, and also extends to a position where it abuts the stopper body 53 of the elevation stopper 52. Luggage 1

An optical fiber cable 55 is inserted through b. That is, when the baggage 1 reaches the back side of the stopper main body 53, the optical signal from the optical fiber cable 55 is blocked, the contacts of the optical switch LS2 open and close, and the carrying-in of the baggage 1 is detected. Note that 56 is a support bracket fixedly attached to the frame 30a and the bracket 30b, and supports the front and rear of the lateral feed roller 29a. Next, regarding the loading fork 57 and the pusher 58, the seventh
The explanation is given with reference to the drawings and FIG. The frame 30a of the loading device 3o includes electric motors Ml, M.
2 is arranged, and its output shaft 60.60a is connected to the binions 62, 62a through the chain sprocket 61.61a.
It is linked to C. This binion 62.62a has a rack 64.64 which is slidable along a guide 63 fixed to the frame 30a.
a is engaged, and if the electric motors Ml and M2 are driven appropriately, the ranks 64 and 64a can move forward and backward simultaneously or independently. On the other hand, a loading fork main body 65... and a pusher main body 66... are arranged between the adjacent horizontal feed rollers 29a, and the lower end of the loading fork main body 65.phi. It is fixed integrally with the trolley 5a, and this mounting plate h65a is fixed to the rack 64a. These loading fork bodies 65 and their advance/retreat drive devices constitute a loading fork 57, and a sensor L is installed at the tip of the loading fork body 65 to detect contact with the cargo 1.
S3 (see Figure 3) is provided. This sensor L
S3 is to prevent the loading fork main body 65 from coming into contact with the cargo 1 previously loaded in the cargo box 2 and damaging the cargo 1. In addition, the pusher body 66 is attached to the mounting plate 66a.
A torque shaft 68 is rotatably supported on the mounting plate 66a, while a torque shaft 68 is rotatably supported on the mounting plate 66a. A lever 69 is fixed to the torque shaft 68 so as to face the pusher body 66 . Further, one end of an air cylinder 70 is pivotally connected to the lower surface of the rack 64, and its piston rod is connected to the tip of a bell crank 71 fixed to the torque shaft 68. The front end of the above-mentioned 8-69 is in contact with the lower surface of the pusher body 66, and since the air cylinder 70 is extended and contracted by rotating the torque shaft 68 via the bell crank 71, the lever 69 is eventually used. pusher body 6
6 protrudes from the conveyance surface of the transverse feed roller 29a...
Alternatively, it can be raised and lowered. The pusher body 66, the driving device for raising and lowering the pusher body 66, and the driving device for moving the pusher body 66 and the driving device for raising and lowering constitute the pusher 58. - Next, the operation of the present invention will be explained. When a start switch (not shown) is turned on, each of the seven cutuators starts operating, and the cargo l carried into the carrying section [O] is
It reaches the loading device 26 via the depalletizer 16 and the feed conveyor 20. The cargo 1 conveyed to the inclined conveyor 28 of the loading device 26 is transferred onto the loading device 30 by the direction changing device 40 in the raised position, usually by extension of the air cylinder 41. That is, the elevating plate 4 constituting the direction changing device 40
9 is raised, the rear end is continuous with the front end of the inclined conveyor 28, and the conveyance surface by the roller 48, which is rotatably pivoted to the elevating plate 49, rises beyond the conveyance surface of the traverse conveyor 29, and It will slope downward. Therefore, the baggage 1 moves onto the inclined conveyor 28 due to its own weight.
from there onto the stowage device 30. On the other hand, at the same time, the stopper body 53 of the lift stopper 52 is also raised by the expansion of the air cylinder 54, and the load l conveyed by the direction changing device 40 comes into contact with this stopper body 53 and is stopped. Then, the loading of the cargo 1 onto the loading device 30 is detected by the optical switch LS2, and the air cylinders 54 and 41 are contracted in response to this detection signal. As a result, the conveyance surface formed by the rollers 48 of the direction changing device 40 is located below the conveyance surface of the cross conveyor 29, so that the cargo 1 is placed on the cross conveyor rollers 29a of the cross conveyor 29. At the same time, it is transported laterally to the negative side (right side in the embodiment) (see FIG. 9). A timer (not shown) is activated in accordance with the conveyance time for the cargo L to leave the group of direction changing devices 40, and the air cylinders 41 and 54 are again operated to extend, and the lifting stroke and bar 52 are activated.
The stopper main body 53 and the elevating plate 49 of the direction changing device 40 are raised to prepare for the next load l. In this way, the cargo 1 transported to the loading device 30-H
are transferred laterally along their front edges separately, and when they are aligned completely horizontally on the stowage device 30 (10th UgJ and 11th UgJ)
(see figure), the air cylinder 70 operates to contract. When the air cylinder 70 contracts, the torque shaft 68 is transmitted via the bell crank 71! As a result of the rotation in the clockwise direction in FIG. 88, the lever 69 also rotates in the same direction, causing the pusher body 66 to rise along the guide 67 beyond the conveying surface of the traverse conveyor 29. When the lift of the pusher body 66 is completed, the pusher 58 and the loading fork 57 move forward. That is, when electric motors M1 and M2 are driven in normal rotation,
The rotational force rotates the pinion 62.62a through the chain sprocket 61.61a, and the pinion 8.
2, 62a is moved forward along the guide 63.
pushed forward by At this time, since the loading fork main body 65 also moves forward at the same time, when the center of gravity of the load l exceeds the front end of the loading device 2t30,
The cargo 1 is transferred and placed on the loading fork body 65.1:, and together with the push by the pusher body 66, it is stopped at a position beyond the front end of the loading device 30 (see Fig. 12). . In this state, the cargo 1 is placed on the loading fork body 65, and at the same time, its back surface is in contact with the front surface of the boot body 66 located beyond the front end of the loading device 30. When the cargo 1 is loaded in this way, the electric motor M2 is then driven in the reverse direction, and contrary to the above, the rack 6 is loaded.
4a is retracted, and the loading fork main body 65 is retracted. Therefore, the loading fork body 65 supporting the lower surface of the baggage 1 is moved backward while its rear surface is blocked by the pusher body 66, and as a result, the baggage 1 lands on the floor of the cargo box 2 or on top of the baggage 1 that was previously stowed. Descended and stowed (13th
(See figure). After that, the electric motor M1 is driven in reverse, and the air cylinder 7
0 is extended, the pusher body 66 retreats to its normal position via the rack 64 and simultaneously descends along the guide 67 so that its upper end is located below the conveyance surface of the traverse conveyor 29. Next, the @ attaching device 30 is raised by a predetermined amount by a lifting device (not shown) in order to stack the next baggage 1 on top of the previously stowed baggage 1, and prepares for the work of stowing the next baggage 1. In addition, if the lifting position of the loading device 30 is not appropriate,
As the loading fork body 65 moves forward, there is a risk that the tip of the loading fork body 65 will collide with the cargo 1 that has been loaded first, but in that case, the sensor LS3 will detect the moment immediately after the collision, and the electric motor It is designed to stop the rolling and prevent damage to the baggage 1. (Effects) As described above, according to the present invention, the cargo that has been sequentially transferred onto the stacking device by the lateral conveyor is transferred at once by the amount corresponding to the width of the cargo box by the operation of the loading fork and pusher. It is possible to carry out stowage work and improve the work efficiency.
