Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-speed tray loading device, and more particularly to a high-speed tray loading device for carrying an object to be conveyed on a tray and storing a plurality of trays in a magazine. Is.

[0002]

2. Description of the Related Art Conventionally, when a large number of fragile confectioneries or other relatively small articles are conveyed and stored in various production lines, they are carefully and efficiently handled so as not to damage the conveyed objects. There is a need. To meet such a need, it is conceivable to place a predetermined number of objects to be conveyed on a tray, convey them, and package them.

FIG. 18 is a flow chart schematically showing such a transportation / packaging system.
The product (transported object) manufactured in 1 is placed on a tray and transported (step S2), the transported object is taken out from the tray at a predetermined station (unloading step of step S3), and finally packaged (step S4). ).

[0004] However, generally, since there is a difference in the processing capacity of the packaging equipment with respect to the mass production in the manufacturing equipment, the packaging equipments (I), (II), (III) and a plurality of them are required. However, there is a problem that the number of packaging facilities cannot be increased indefinitely because the installation area and cost are limited.

FIG. 19 is a flow chart showing another conveying / packaging system for coping with such a problem, in which a plurality of trays are loaded in a magazine (step S1).
3) By carrying this magazine (step S
14) Mass transport is possible, and in step S15,
The tray is unloaded from the magazine and the transported object is unloaded from the tray and packaged (step S1).
6).

Further, if the packaging process in step S16 is not in time, the magazines are temporarily stored in a three-dimensional warehouse or the like as in step S17, and the magazines are replenished as needed.

FIG. 20 is a perspective view showing a tray 1 and a magazine 2 which are suitable for use in the above-mentioned transport / packaging system. The tray 3 has a loading surface 3 on which articles 4 to be transported such as confectionery are placed side by side. It can be placed on a predetermined carrying path such as a conveyor (not shown), and a pair of reinforcing bent portions 5 and a storage side edge portion 6 are formed at the opposite side ends thereof. .

The magazine 2 has a pair of storage shelves 8 formed on a pair of opposing inner wall surfaces in the storage space 7 inside, and the tray 1 is pushed into the storage shelves 8 by pushing the tray 1 through the front opening 9. The trays 1 are stored in multiple stages in the storage shelf 8 by engaging the storage side edge portions 6 (loading).
In addition to the above, it can be discharged (unloaded) by pushing out from the rear opening 10 using a tray pusher (not shown) or the like.

On the front side of the storage rack 8, an inclined portion 11 for preventing the tray from popping out is inclined upward toward the outside.
To form the X direction, the Y direction of the magazine 2,
Alternatively, it is possible to prevent the tray 1 from popping out during its transportation such as rotation. The depth length of the inclined portion 11 for preventing the tray from popping out is L.

A reciprocating type is conventionally used as a loading device for packing the trays 1 in the magazine 2. FIG. 21 is a schematic cross-sectional view of a conventional one-stage reciprocating type loading device 20. The magazine 2 is conveyed and arranged by a magazine conveyor 21 with its front opening 9 facing the front position of the loading device 20. To do.

The loading device 20 includes a vertically movable loading frame 22, a frame elevating device 23 for elevating the loading frame 22, a tray 1 loading conveyor 24, an aligning conveyor 25, and a tray pushing head 26. The tray pushing head 26 has a pushing cylinder 27 that reciprocates, and a tilt cylinder 28 that horizontally tilts the pushing cylinder 27. In addition, in each of the following drawings, a driving motor is denoted by a symbol "M".

In the single-stage reciprocating type loading device 20 having such a structure, the tray 1 on which the objects to be conveyed from the production line are loaded is carried in by the carrying-in conveyor 24 and is aligned per storage shelf 8 of the magazine 2. Only the number of trays 1 are aligned by the aligning conveyor 25.

When a predetermined number of trays 1 are lined up on the aligning conveyor 25, the tilt cylinder 28 prepares the pushing cylinder 27 in the horizontal position at the rear end portion of the tray 1 and drives the pushing cylinder 27 to drive the tray pushing head. 26
Thus, a plurality of trays 1 are pushed into the storage shelves 8 of the magazine 2.

Next, the frame elevator 23 lifts up the entire loading frame 22 by one stage of the storage rack 8, and by a similar operation, a plurality of trays 1 are pushed and stored in the second storage rack 8. . After that, a large number of trays 1 are stored in the magazine 2 by repeating the same operation.

However, in the one-step reciprocating type loading device 20 which reciprocates the tray pushing head 26 based on the above-mentioned structure, the pushing cylinder 27 is used for each operation of loading, aligning and pushing the tray 1.
A reciprocating and elevating cycle is required every time the tray 1 is aligned.

That is, the tray pushing head 26 needs to be reciprocated in the horizontal plane and moved up and down in the vertical plane, so that the tray pushing head 26 can be retracted and aligned in one cycle of the pushing cycle. Since the descending operation of the conveyor 25 does not contribute to the actual tray pushing operation, it requires at least twice the operation time as compared with the continuous operation, and the transfer speed of the aligning conveyor 25 and the tray pushing head 26 is the same. In such a case, there is a problem that the operation time is required to be four times as long as a simple calculation, and the efficiency is unavoidable.

In order to solve such a problem, a method of simultaneously pushing a plurality of trays 1 in a multi-stage (for example, four stages) into four storage shelves 8 in the magazine 2 can be considered. 22 is a schematic cross-sectional view of such a multi-stage reciprocating loading device 30, and FIG. 23 is XXIII- of FIG.
FIG. 6 is a cross-sectional view taken along the line XXIII in which a multistage reciprocating loading device 30 includes a carry-in conveyor 24, an aligning conveyor 25, a multistage vertical conveyor 31, and a tray corresponding to four tray pushing heads 26. Pushing head 3
2, a pushing cylinder 33 that can reciprocate the tray pushing head 32 and can be raised and lowered, and a cylinder lifter 34 that raises and lowers the pushing cylinder 33.

As shown in FIG. 23, the multi-stage vertical conveyor 31 has tray holding portions 35 formed in pairs, and the trays 1 are held horizontally and in a multi-stage manner between the tray holding portions 35. It can be raised and lowered to a predetermined position.

In the multi-stage reciprocating type loading device 30 having such a structure, the trays 1 aligned on the aligning conveyor 25 are sequentially lifted by the multi-stage vertical conveyor 31, and the pushing cylinder 33 is driven when four stages are accumulated. The tray pushing head 32 pushes the four trays 1 into the magazine 2 at the same time.

Therefore, although the loading efficiency can be increased as compared with the single-stage reciprocating type loading device 20 shown in FIG. 21, the structure is complicated and the storage racks 8 of the magazine 2 can be simultaneously trayed in multiple stages. Since 1 is pushed in, when the trays 1 are raised to each other in any one of the four trays during such a loading operation, the so-called restoration work of removing the raised tray 1 is extremely difficult. There is a problem. This problem of difficulty in recovery imposes a very large obstacle in practical use of system operation.

In addition, instead of the reciprocating type loading devices such as the one-stage type reciprocating type loading device 20 and the multi-stage type reciprocating type loading device 30 described above, the tray 1 is continuously pushed although it is a single-stage type. A possible single-stage continuous loading device 40 is conceivable. Figure 2
4 is a schematic side view of such a one-stage continuous loading device 40. In this loading device 40, a pushing conveyor 41 is arranged so as to face the front opening 9 of the magazine 2.

A pair of pushing plates 42 are attached to the pushing conveyor 41 with a phase difference of 180 degrees, for example, the tray holding portion 3 for one stage of the multistage vertical conveyor 31.
The plurality of trays 1 arranged on the tray 5 are pushed into the storage racks 8 of the magazine 2 by the pushing plate 42 as the pushing conveyor 41 rotates.

When the storage of one tray 1 is completed, the magazine 2 is raised or lowered to place the empty storage shelf 8 at the loading position.

In the single-stage continuous loading device 40 having such a construction, the pushing conveyor 41 and the pushing plate 42 are the tray pushing head 26 (FIG. 21).
Alternatively, since the reciprocating operation and the lifting operation like the tray pushing head 32 (FIG. 22) are not required, highly efficient and high-speed pushing operation is possible, and the one-stage type allows the tray 1 to be raised and other lines to be stopped. Even if it is unavoidable, recovery work is easy.

However, as shown in the drawing, in order to push the tray 1 into the storage rack 8 of the magazine 2, the tray 11 is pushed inward by the depth L of the inclined portion 11 (FIG. 20) for preventing the tray from popping out. Despite the need to push the tray 1 completely, the push plate 42 and the sprocket 43 cannot extend beyond the front opening 9 into the storage space 7.

That is, since the pushing plate 42 and the sprocket 43 need to perform the reversing action at the site of the front opening 9 of the magazine 2, the semicircular range shown by the imaginary line in the drawing is the approach limit. This is because when the pushing conveyor 41 is positioned so as to extend the pushing plate 42 into the storage space 7, the pushing plate 42 collides with the upper wall surface or the lower wall surface of the magazine 2 in the upper or lower stage of the storage space 7 and the tray 1 It is impossible to push in.

Therefore, in a reciprocating type loading device such as the one-stage reciprocating type loading device 20 or the multi-stage reciprocating type loading device 30, the pushing stroke of the tray pushing head 26 or the tray pushing head 32 is simply controlled. Although the pushing operation of the tray 1 can be easily performed by the above, the tray 1 projects from the front opening 9 of the magazine 2 by the length T in the continuous loading device such as the one-stage continuous loading device 40. Therefore, there is another problem that the advantages of the continuous pushing mechanism cannot be exhibited.

[0028]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is relatively small in size and a large number of objects to be conveyed are placed on a tray and conveyed, and the tray is stored in a magazine.
