DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of supplying individually stocked block pieces such as biscuits in a state of being stacked in a plurality of stages.

[0002]

2. Description of the Related Art In some cases, biscuits and the like having different colors and tastes are wrapped in two layers. In such a case, the individually manufactured biscuits are separately stocked and supplied to the packaging section in a two-tiered state. Conventionally, a method as shown in FIGS. 1 and 2 has been adopted as a method for the two-stage stacking.

In this conventional method, the upper confectionery pieces (A ₂ ) and the lower confectionery pieces (A ₁ ) are stored in a stacked state in separate hoppers, and these hoppers are connected to the upstream side of a linear transfer path. They are arranged in series at a certain interval on the downstream side. The transfer path is a main transfer table (1a) for slidingly transferring the upper confectionery pieces (A ₂ ) and the lower confectionery pieces (A ₁ ), and the main transfer table (1a).
Slit (S) formed along the longitudinal direction
And a transfer rod projecting from below with respect to the slit (S).
(11) Consisting of a loop-shaped traveling body (10) such as a chain provided with (11) at regular intervals, and the upper confectionery pieces (A ₂ ) (A ₂ ) in the downstream hopper are (1a) is supported by an auxiliary transfer table (1b) provided in parallel with this, and a slit for inserting the transfer rod (11) into this auxiliary transfer table (1b).
(S) is formed.

In this apparatus, the auxiliary transfer table (1b) is extended from the downstream hopper by a certain range to the downstream side, and the distance between the auxiliary transfer table (1b) and the main transfer table (1a) is smaller than the lower confectionery piece.
The thickness is approximately equal to the thickness of (A ₁ ). Accordingly, when the transfer rod (11) reaches the hopper on the upstream side, the lower confectionery piece (A ₁ )
Is pushed out by this transfer rod (11), and the main transfer table (1a)
Is transported along. When the transfer rod (11) reaches the hopper on the downstream side, the lower upper confectionery piece (A ₂ ) supported by the auxiliary transfer table (1b) is pushed out to the downstream side. This allows
When the upper confectionery piece (A ₂ ) and the lower confectionery piece (A ₁ ) are simultaneously pushed out to the downstream side and come off the auxiliary transfer table (1b), they become a two-stage stacked state, and in this state, the main transfer table ( It is transported downstream along 1a).

In this conventional apparatus, the configuration is simple, but the upper confectionery pieces (A ₂ ) and the lower confectionery pieces (A ₁ ) stocked in the hopper are forcibly pushed out by the transfer rods (11), (11). Therefore, a frictional force acts between the upper confectionery pieces and, in the case of fragile confectionery pieces such as biscuits,
Chipping occurs during the pushing operation from the hopper. Further, there is a case where the pushing operation cannot be performed smoothly.

The present invention has been made in view of such a point, and in the above-described method of stacking and supplying block pieces, in the process until the block pieces are stacked, the block pieces are not chipped. And to make the stacking operation smooth. [Invention of Claim 1]

[0007]

[Technical Means] The technical means of the present invention for solving the above-mentioned problem includes a main transfer table (1a) for transferring a plurality of block pieces (A) and (A) while sliding them in a stacked state, A transfer rod (11) (1) that runs in an upright posture along the upper surface of the main transfer table (1a).
The number of stacks of the loop-shaped traveling body (10) provided at a predetermined pitch and the block pieces (A) (A) provided so as to merge at the upstream part of the transfer path of the main transfer table (1a) And the same number of input transfer devices (2) and (2), and the input transfer devices (2) and (2) are main-transferred so as to have an interval between junctions with the main transfer table (1a). Each transfer device for loading is installed diagonally to the table (1a)
The block (A) transferred by (2) is the main transfer table (1a)
To the main transfer table (1a) of the upstream transfer device (2) and the main transfer table (2) of the downstream transfer device (2). An auxiliary transfer table (1c) that is parallel to the main transfer table (1a) after rising from the upper surface of the main transfer table (1a) to the downstream side is provided between the junction with 1a) and the auxiliary transfer table. The distance between the horizontal part of the transfer table (1c) and the main transfer table (1a) is set to be larger than the thickness of the block pieces (A) or the stacked block pieces (A) and (A) to be charged downstream. And
The slit (S) extending in the longitudinal direction in the auxiliary transfer table (1c)
The transfer rods (11) and (11) are made to travel in a mode penetrated by the transfer rods (11) and (11).
After passing through the junction of the main transfer table (1a), the block piece (A)
(A) was intermittently put in.]

[0008]

The above technical means operates as follows. In the upstream part of the main transfer table (1a), the block pieces (A) and (A) are individually charged by the charging transfer devices (2) and (2) from diagonally rearward. Then, after the transfer rod (11) has passed the junction of the input transfer device (2) and the main transfer table (1a), the block pieces
(A) is charged from the charging transfer device (2) to the main transfer table (1a). Therefore, the block piece transferred to the main transfer table (1a)
(A) (A) is moved downstream along the main transfer table (1a) by the transfer rod (11).

The main transfer table (1) of the input transfer device (2) on the upstream side
a), and the downstream transfer device for input
(2) between the main transfer table (1a) and the junction with the main transfer table (1a).
Since the auxiliary transfer table (1c) that is parallel to the main transfer table (1a) after being raised from the upstream side to the downstream side on the upper surface of (a) is provided, the block piece (A) that is input on the upstream side Is a block piece (A) which is supplied on the downstream side by the auxiliary transfer table (1c).
When the transfer rod (11) coincides with the block piece (A) input at the downstream junction, the block piece (A) placed on the main transfer table (1a) and the auxiliary transfer When the block piece (A) placed on the table (1c) is simultaneously moved downstream by one transfer rod (11) and comes off the downstream end of the auxiliary transfer table (1c), it is thrown in on the upstream side. The block pieces (A) placed on the main transfer table (1a) are stacked on the block pieces (A) charged on the downstream side and transferred to the downstream side by the transfer rod (11). Becomes

When the number of stacks is three or more, an (N-1) auxiliary transfer table (1c) is prepared for the number of stacks N, and the auxiliary transfer table (1c) on the most upstream side is provided. The uppermost block piece (A) is transported along the
The lower block pieces (A) are successively transported along and are stacked with the lower block pieces (A) by the above-described operation when the end points of the auxiliary transfer tables (1c) are deviated.

Incidentally, the transfer devices (2) and (2) for charging the main transfer table (1
The above-mentioned effects can be obtained both when joining obliquely from below to a) and when joining obliquely behind the main transfer table (1a) on the horizontal plane.

[0012]

[Effect] The block (A) (A) which is intermittently fed at a predetermined timing by the input transfer device (2) (2) is used as the main transfer table.
Since they are superposed during the transfer on the upper surface of (1a), there is no inconvenience such that the block piece (A) is chipped due to excessive force applied when escaping from the hopper as in the related art.

By synchronizing the traveling speed of the transfer rod (11) and the charging speed of the block piece (A) by the charging transfer device (2), even if both speeds are high, the block piece (A) can be smoothly moved. And (A) can be supplied in a stacked state. Therefore,
The supply speed in the case where the individually supplied block pieces (A) and (A) are supplied in a stacked state can be increased.

In addition, the upstream end of the main transfer table (1a) is located at a position downstream of the small diameter sprocket (13). As described above, even if the movement locus of the lower end of the transfer rods (11) is along the horizontal plane, it does not interfere with the side wall of the main transfer table (1a) during this movement.

[About the main transfer table (1a)] The main transfer table (1a)
Is basically formed in a U-shaped cross section, and the side walls on both sides of the confectionery piece mounting surface having a width slightly larger than the length of the short side of the block-shaped confectionery piece are formed by stacking the confectionery pieces in two stages. The height is almost the same as the height in the stacked state. Two feeding transfer devices (2) and (2) are provided to join the main transfer table (1a) from the outer peripheral region of the traveling region of the loop-shaped traveling body (10), and these feeding transfer devices (2) The junction with (2) is set on the upstream end of the main transfer table (1a) and on the downstream side at a certain distance from the upstream end. As shown in FIGS. 6 and 7, a conveyor belt is employed as each of the charging transfer devices (2), and the transfer surface of the charging transfer device (2) is the same height as the upper surface of the main transfer table (1a).

In this embodiment, the inclination angle between the main transfer table (1a) and the input transfer device (2) is set to about 15 degrees.

An auxiliary transfer table (1c) is provided within a certain range from the vicinity of the downstream side of the junction of the upstream transfer device (2). The auxiliary transfer table (1c) includes an inclined surface that rises obliquely and a horizontal surface that follows the inclined surface. The space between the horizontal surface and the main transfer table (1a) is the lower confectionery piece as a block piece (A).

In the center of the auxiliary transfer table (1c), a slit (S) is formed in the whole area in the longitudinal direction, and the transfer rod (11) runs in the slit (S). [About the transfer device (2) for charging] The transfer device (2) for charging
Is a conveyor belt, which is associated with a continuous supply and transfer belt (2b) provided upstream of the conveyor belt, and is primary when transferred from the continuous supply and transfer belt (2b) to the input transfer device (2). This input transfer device (2) runs at high speed. Therefore, the charging transfer device (2) operates in such a manner that the high-speed state and the low-speed state are alternately repeated, and the charging transfer device (2)
The block pieces (A) and (A) are transferred to the main transfer table (1a) side in a state of being arranged at regular intervals on the transfer surface. At the downstream end of the charging transfer device (2), the charging transfer device (2) is moved from the charging transfer device (2) to the main transfer table (1) when the charging transfer device (2) is in a high speed range.
The configuration can be transferred to a).

The block piece (A) transferred to the main transfer table (1a) side has a condition that the transfer direction matches the longitudinal direction of the block piece (A), and further, the block piece (A) is obliquely rearward.
Since the block pieces (A) transferred to the main transfer table (1a) side are eventually pushed into the main transfer table (1a)

The transfer rod (11) travels at a constant speed, and the arrangement interval of the transfer rods (11) in the loop-shaped traveling body (10) is set to be constant. Then, the transfer rod (11) is
Immediately after passing through the junction with (2), the block piece (A) is fed from the charging transfer device (2) to the main transfer table (1a).

In order to execute this operation, the traveling speed of the loop-shaped traveling body (10), the traveling speed of the charging transfer device (2) and the length of the charging transfer device (2) are adjusted to the above conditions. Needless to say, it is set. In the above embodiment, the charging transfer device (2) is a conveyor belt that operates in such a manner that a high-speed state and a low-speed state are alternately repeated, and the block pieces (A) are directly transferred to the main transfer table (1a). )
However, a conveyor belt running at a constant speed between the high-speed state and the low-speed state may be connected to the downstream side of the conveyor belt, and the latter conveyor belt may be used as the input transfer device (2).

Immediately after passing through the junction with the upstream transfer device (2), the upper confectionery piece (A ₂ ) is transferred from the transfer device (2) to the auxiliary transfer table (1c). After this, the subsequent transfer rod
When (11) moves to the input section of this upper confectionery piece (A ₂ ),
The upper confectionery piece (A ₂ ) is moved downstream by the transfer rod (11) and, when reaching the auxiliary transfer table (1c), is pushed up from the inclined surface to the horizontal surface.

Prior to this, immediately after the preceding transfer rod (11) has passed the junction with the downstream transfer device (2), the main transfer table (1a) and the auxiliary transfer table ( Between 1c), the lower confectionery pieces (A ₁ ) are transferred from the charging transfer device (2). Then, the subsequent transfer rod (11) is connected to the lower confectionery piece (A
At the time of coincidence with ₁ ), the upper upper confectionery piece (A ₂ ) and the lower lower confectionery piece (A ₁ ) are both moved downstream. And
Since these lower confectionery pieces (A ₁ ) and upper confectionery pieces (A ₂ ) are located vertically, when they come off the downstream end of the auxiliary transfer table (1c), they become stacked and become the main transfer table (1a). Upper transfer rod (1
It is moved downstream by 1).

When the lower confectionery piece (A ₁ ) and the upper confectionery piece (A ₂ ) in the stacked state reach the downstream end of the main transfer table (1a) by the transfer rod (11), the downstream transfer table ( It is transferred to 1e) and transferred to the downstream bottom along this transfer table. Since the height of the side wall of the downstream transfer table (1e) is set lower than the movement locus of the lower end of the transfer rod (11), the transfer rod (11) is moved by the large-diameter sprocket (12). ), The downstream transfer table (1e) does not interfere with the movement path of the transfer rod (11).
