The product 5 ₃ piled thereon, ... are dropped onto the pusher 3 in phantom line position, returns to the initial state by the pusher 3 returns to the solid line position.

A conventional drive mechanism 4 is such that a gear motor 8, sprockets 9a and 9b, and an endless body 10 are assembled to a drive mechanism casing 7 as shown in FIG. 10 to form a projection 11 formed on the endless body 10. The pusher 3 is engaged with a pusher 3 supported so as to be able to reciprocate linearly, and the pusher 3 is driven by a gear motor 8.

[0006]

The conventional drive mechanism 4 has a bearing 12 formed on a drive mechanism casing 7.
The endless body 10 is provided outside the drive mechanism casing 7 so that the shafts of the sprockets 9a and 9b are inserted into the shafts a and 12b and the sprocket 9a is inserted into the output shaft 13 of the geared motor 8.
It is necessary to assemble the drive mechanism casing 7 after the sprockets 9a and 9b are set in this state, and the workability of the assembly is poor.

An object of the present invention is to provide a drive mechanism that is easy to assemble.

[0008]

The drive mechanism of the present invention pushes the rear end of the lowermost product of the product group directly stacked in the product stacking path with the front end of a linearly reciprocatingly driven pusher. In a direct stacking type product unloading device that unloads products from a front opening of a product stacking path, an output shaft of a power source is arranged at a bottom of a drive mechanism casing, and a fixed gear is provided around the output shaft at a bottom of the drive mechanism casing. A first shaft that engages with the output shaft and rotates about the output shaft.
And a moving gear pulled out above the first rotating plate through a through hole formed in the first rotating plate, the lower end of the first rotating plate being meshed with the fixed gear. A second rotating plate pivotally supported at a position near the through-hole on the upper surface and formed with a gear meshing with an upper end of the moving gear is provided on the lower surface, and the pusher supported so as to be able to reciprocate in a straight line is provided on the second rotating plate.
Characterized by being engaged with the outer peripheral portion of the upper surface of the rotating plate.

[0009]

According to this structure, when the output shaft rotates and the first rotary plate rotates, the moving gear set in the through hole of the first rotary plate moves. The moving gear meshed with the fixed gear moves while rotating, the second rotating plate is driven by the rotating fixed gear, and the tip of the second rotating plate linearly reciprocates the pusher.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 9 and 10 showing the conventional example will be described with the same reference numerals.

The drive mechanism 4 of the present invention is, as shown in FIG.
A fixed gear 14 fixed to the bottom of the drive mechanism casing 7
And a stop detection microswitch 15 are provided. An output shaft 13 of the geared motor 8 extends from the center of the fixed gear 14 into the drive mechanism casing 7, and the first rotating plate 16 is fitted on the output shaft 13 and is driven to rotate.

The lower end 18a of the moving gear 18 inserted into the through hole 17 of the first rotating plate 16 meshes with the fixed gear 14. First
A shaft 19 is implanted at a position near the through hole 17 on the upper surface of the rotating plate 16, and a second rotating plate 20 is pivotally supported on the shaft 19. A gear 21 meshing with the upper end b of the moving gear is formed on the lower surface of the second rotating plate 20, and a shaft 22 is implanted on the upper surface of the second rotating plate 20.

A locking projection 23 to which the pusher 3 is attached is inserted through a shaft 24, and both ends of the shaft 24 are inserted into and supported by holes 25a and 25b formed in a side wall of the drive mechanism casing 7. The shaft 22 of the second rotating plate 20 is engaged with the hole 26 on the back surface of the locking projection 23.

The pusher 3 is configured as shown in FIG. The pusher 3 includes a pusher body 3a and an auxiliary body 3c one end of which is pivotally supported by shaft portions 3b formed at both ends of the back surface of the pusher body 3a. A projection 3d is formed on the back surface of the other end of the auxiliary body 3c.

As shown in FIG. 7, a lid 27 is attached to the upper opening 7a of the drive mechanism casing 7, and the upper surface of the lid 27 is the product stacking surface 1. As shown in FIG. An opening 28 through which the locking projection 23 is inserted is formed at the center, and a long hole 29 with which the convex portion 3d of the auxiliary body 3c engages is formed at both sides thereof.

With this construction, when the locking projection 23 is in the initial position as shown in FIG. 2, the pusher 3 is moved to the rear opening of the product stacking path 1 as shown in FIGS.
In the state located at 30, the auxiliary body 3c in which the convex portion 3d is engaged with the elongated hole 29 is rotating to the side of the pusher main body 3a.

When the output shaft 13 starts to rotate clockwise (in the direction of arrow F) upon detection of a product dispensing instruction, the first rotating plate 16 causes the moving gear 18 meshing with the fixed gear 14 to be rotated by the first rotating plate 16.
Move along the outer circumference of.

The movement of the moving gear 18 causes the moving gear 18 to move.
18 rotates clockwise, the second rotating plate 20 rotates counterclockwise about the shaft 19 as shown in FIG. 3, and the locking projection 23 advances in the direction of arrow G along the shaft 24. Initiate reciprocation.

The locking projection 23 reaches the advanced position shown in FIG. 4 by the output shaft 13 is further rotated, product 5 ₁ merchandise stacked extruded by the pusher 3 reaches the forward position as shown in FIG. 8 Fall from surface 1.

The locking projection output shaft 13 even after the product 5 ₁ is carried out is engaged to continue to rotate in the clockwise direction, the second rotation plate 20
23 starts the backward movement from the forward position to the initial position.
At the end of the return movement, as shown in FIG. 5, the micro switch 15 detects the first rotary plate 16 and immediately after the peak H of the first rotary plate 16 has passed over the sensing lever 31 of the micro switch 15, the geared motor 8 is turned on. Is turned off and the return is completed.
When the locking projection 23 and the pusher 3 arrive at the initial positions shown in FIGS. 2 and 7, one operation is completed.

As described above, the driving mechanism 4 of the present invention, which can reciprocate the pusher 3 linearly, only needs to incorporate each component one by one as shown in the exploded view of FIG. Easy to assemble compared to

[0022]

As described above, according to the present invention, the output shaft of the power source is arranged at the bottom of the drive mechanism casing, and a fixed gear is provided around the output shaft at the bottom of the drive mechanism casing. And a first rotating plate which rotates about the output shaft is provided, the lower end of the first rotating plate meshes with the fixed gear, and the upper end of the first rotating plate passes through a through hole formed in the first rotating plate. A second rotating gear provided with a moving gear drawn out above the plate, the upper surface of the first rotating plate pivotally supported at a position near the through hole, and the lower surface formed with a gear meshing with the upper end of the moving gear; A plate is provided, and the pusher supported so as to be able to reciprocate linearly is engaged with the outer peripheral portion of the upper surface of the second rotating plate. Therefore, when the output shaft rotates and the first rotating plate rotates, the first rotating plate rotates. The moving gear set in the through hole of the rotating plate moves,
The movement of the moving gear meshed with the fixed gear moves while rotating, the second rotating plate is driven by the rotating rotation of the fixed gear, and the tip of the second rotating plate can drive the pusher in a linear reciprocating manner, thereby reducing the assembly time. In terms of point, since it is only necessary to incorporate each component one by one, it is easier to assemble than a conventional drive mechanism.
