Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a pallet loading device, and in particular in the driving part of its moving plate.

The moving plate of the pallet loading device makes linear reciprocating motion during operation, but its drive mechanism is
It consists of a traction mechanism consisting of a chain and the like driven by a motor.

Therefore, in the conventional pallet loading device, the moving plate generates a large impact at the start and end points of the movement, which is undesirable, and the structure is also complicated.

The purpose of the present invention is to eliminate the above-mentioned drawbacks, to reduce the impact at the starting and ending points of the movement of the moving plate, and to simplify the structure.

The invention of the present application includes a sorting table that supports the lined up cargo, a pusher that is provided at the position of the sorting table and moves the lined up cargo to a loading position,
A moving plate that receives the aligned items at the loading position and retreats to a standby position during pallet loading, a groove-shaped driven part provided on this moving plate in a direction crossing the moving direction, and this driven part. an arm that connects the top and bottom parts and is rotated by a rotary drive means; a stopper that prevents the aligned loads on the moving plate from moving when the moving plate moves to the standby position; The platform is provided with a lifting platform which receives the cargo aligned on the moving plate with a cargo handling pallet when the moving plate is retracted.

Hereinafter, the present invention will be specifically explained based on an embodiment shown in the drawings.

The pallet loading device 1 of the present invention includes an alignment table 2,
pusher 3, moving plate 4, groove-shaped driven part 5,
It is composed of an arm 6, a stopper 7, and a lifting platform 8. The sorting table 2 is fixed at a sorting position and is used to line up a plurality of pieces of baggage 10.
It is carried by the carry-in conveyor 12 and stopped by the stopper 13. Note that a press plate 14 for sending out the luggage 10 is provided at the position of the carry-in conveyor 12. Also, a pair of guide plates 15 on the alignment table 2
are provided in a figure eight shape when viewed from above in order to align the luggage 10.

For example, two pushers 3 are provided on the above-mentioned sorting table 2, and are used to move a plurality of aligned items 10 to a loading position, that is, above the lifting table 8. A pair of endless chains 17 are wound around the four arranged chain foils 16 in an opposing state, and supported by the chains 17 in a substantially horizontal state. The pair of chains 17 are simultaneously driven by an upper drive shaft 18. This driving source is a motor 19, the rotational force of which is transmitted by chain wheels 20, 21 and a chain 22.

As clearly shown in FIGS. 2 and 3, the moving plate 4 receives a plurality of items 10 aligned in a loading position, that is, the position of the lifting platform 8, and retreats to a standby position when loading a pallet. , is supported horizontally between a pair of guide rails 23 by a support roller 24 and a guide roller 25 so as to be movable. The driven portion 5 is provided on the lower surface of the moving plate 4 and is configured to extend in a direction intersecting the moving direction. The arm 6 is connected to the groove-shaped driven portion 5 by a roller 26 at one end thereof. The rotational drive means is a motor 9, and the rotation of this motor 9 is transmitted by a stepless reduction gear 27, a coupling coupling 28, and a reduction gear 29. Here, the length of the arm 6 is equal to the stroke S1/2 of the moving plate 4, and the length of the groove-shaped driven portion 5 is at least twice the length of the arm 6.

Further, the stopper 7 is configured to stop the plurality of items 1 aligned on the moving plate 4 when the moving plate 4 is moved to the standby position.
The stopper 7 in this embodiment is also used as the aforementioned pusher 3.
As shown in FIG. 3, the elevating platform 8 is provided below the loading position, and receives a plurality of cargoes 10 that are aligned when the movable plate 4 is moved on a cargo handling pallet 11. It is supported so that it can be raised and lowered freely.

Note that the fixed stopper 30 is fixed to the machine frame 31 at the loading position, and is also fixed to the guide plates 32, 33.
is attached to the machine frame 31 in order to guide the cargo 10 on the side of the loading position.

Next, the operation will be explained. A plurality of packages 10 are sent in by a carry-in conveyor 12, and a stopper 13
For example, 3 pieces are lined up in a line. In this state, the pressing plate 14 is driven by an air cylinder or the like to move forward and push the three items 10 onto the alignment table 2. By repeating such operations, six pieces of luggage 10 are arranged on the arrangement table 2. After this, the chain 17 rotates in the direction of the arrow, and the pusher 3 also moves at the same time. The pusher 3 presses the aligned loads 10 and moves them onto the moving plate 4 at the loading position. Next, the arm 6 rotates, for example, clockwise, so that the moving plate 4 retreats to the standby position. At this time, the pusher 3 acts as a stopper 7, and the loads 1 are aligned on the moving plate 4.
Preventing 0 from retreating. Therefore, luggage 10 is
They descend while remaining aligned and get on top of the pallet 11. At this time, the elevator platform 8 is lowered by the height of the load 10 on which it is placed, and is ready to receive the next load 10. During this time, the arm 6 rotates once to return the moving plate 4 to the pallet loading position. In this way, the next cargo 10 is loaded onto the pallet 11 one after another.

Note that the retracted position of the moving plate 4 is the same as that of the alignment table 2.
It doesn't have to be at the bottom. In addition to rotating the arm 6 once, it may also be rotated back and forth by half a rotation. Furthermore, the stopper 7 may be provided so as to move up and down separately without being used also as the pusher 3.

The present invention has the following effects.

When the first arm rotates at a constant angular velocity, the velocity of the moving plate varies as a sinusoidal function, providing motion damping when the moving plate starts and stops.

Second, since the initial movement amount of the moving plate relative to the rotation amount of the arm is small, the rotational force of the arm rotation driving means may be small.

Thirdly, since the rotation drive means can be placed below the alignment table, the apparatus can be made smaller.

Fourthly, unlike the conventional traction mechanism consisting of a chain, there is no need for a guide rail for guiding the chain or a sprocket for guiding and driving the chain, which simplifies the structure.

Fifth, since drive can be transmitted simply by engaging the tip of the arm with the groove-shaped driven portion, the drive system also has a simple structure.
