DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for arranging and counting bar-shaped products, and relates to confectionery such as chocolate bars that are in a misaligned state.

In this system, bar-shaped products such as foods are moved one by one at intervals, and after a predetermined count, they are arranged and sequentially stored in one box with an open top.

Conventionally, when placing a predetermined number of bar-shaped products such as confectionery and foods such as chocolate bars in a box with an open top, the number of bar-shaped products was counted by hand and then fed into the box, which required a lot of labor and labor. It was time consuming and inefficient.

For this reason, there has been a recent demand for automation in this direction.

In consideration of these points, the present invention provides an apparatus that automatically and efficiently performs all of the boxing process operations by automatically saving labor and performing them continuously and uniformly.

That is, in this invention, a bar-shaped product 1 such as a chocolate bar is fed to a feeder 3. Each gap 7 is provided by providing a crosspiece 6 which is allowed to fall onto the belt conveyor 4 and freely rotates while forming a gap 7 at a constant interval on both outer frames, and a plate 13 having an inclined portion on the lower surface of the crosspiece 6. A chain conveyor 5 that transfers the bar-shaped products 1 that have entered the product while being received by a plate 13, and a belt that is provided at a distance below the tip of the chain conveyor 5 and that accommodates and transfers the bar-shaped products 1 that fall from the chain conveyor 5 under its own weight. A conveyor 9 and a bar-shaped product 1 that is provided near the falling position of the bar-shaped product onto the belt conveyor 9.
A light emitting tube 8 for counting and stopping the operation of the feeder 3, belt conveyor 4, and chain conveyor 5 when a certain amount is reached. A counting and operation stop device including a light receiving tube 8', and a plurality of belt conveyors 9 that are rotated in a direction perpendicular to the traveling direction of the belt conveyor 9 and that transport rows of bar-like products 1 having a constant interval and reaching a constant quantity from the peltocospair 9. a chain conveyor 11 to which several attachments 12 are attached; a support plate 14 provided below the attachments 12 to support the bar-shaped products 1 to be transferred; and a receiver for receiving the bar-shaped products 1 that fall in parallel below the tip of the support plate 14. Plate 19 line and receiving plate 19
It is characterized in that it includes a protruding metal fitting 15 that slides on the top and accommodates the bar-shaped products 1 in the box 2 so that their lengths are adjacent to each other.

Next, embodiments of the device according to the present invention will be described with reference to the drawings.

As shown in Figure 2, a predetermined number of bar-shaped products 1 (hereinafter referred to as "products") such as bar chocolates that are lined up this year are lined up, that is, the short parts are placed next to each other, and the tops are opened. The filling operation is performed using a series of devices shown in FIGS. 1, 3, and 4.

First, in the plan view of Fig. 1, 3 is a well-known spiral vibrating feeder, into which the products 1 that are being conveyed in a misaligned manner are placed, guided by vibration, and gradually moved toward the outer circumference. The chain conveyor 5 is transferred onto the belt conveyor 4 in a linear direction and advances (in series) with the length direction as the traveling direction, and the crosspieces 6 which are provided at a constant interval on both outer frames of the chain conveyor 5 and freely rotate, and the gap 7 between the adjacent crosspieces 6. Product 1 is introduced one by one.

The chain conveyor 5 advances in the direction of the arrow as shown in FIG. 3 (front view in the entry direction of FIG. Move forward.

In this case, the plate 13 of the receiver is composed of a low part 13a, a high part 13c, and an inclined part 13b, and a part of it is made into an inclined shape because it is a product that does not fit into the gap γ between adjacent crosspieces 6 and gets caught in the middle. 1 rests on the crosspiece 6 due to its inclination, and due to its weight and the free rotation of the crosspiece 6, it slides down and enters an appropriately empty gap 7 below. It is possible to prevent the product 1 from being transferred until the end.

In this way, the products 1 that have entered each gap 7 move forward as the chain conveyor 5 advances while being held between each crosspiece 6, and the receiver disappears at the end of the plate 13, so that the product 1 is transferred from the gap 7 to the top of the belt conveyor S. The pieces naturally fall one by one due to their weight.

At this time, a pair of light emitting tubes and light receiving tubes 8 for detecting articles are provided on both sides of the belt conveyor 9 so as not to obstruct its progress.
, 8' count the products 1 falling onto the belt, and when a predetermined number of products have fallen, the progress of the chain conveyor 5 is automatically stopped.

This is because the amount of light received by the light receiving tube 8' is interrupted every time the product 1 passes by, and the amount of light received by the light receiving tube 8' is blocked for a certain amount of light from the arc tube 8, and is connected to a counting device to perform counting, and when a predetermined number of counting is completed, a relay or switch is used. At the same time, the feeder 3 and belt conveyor 4 are stopped, and the movement of the subsequent products 1 is temporarily stopped.

On the other hand, the products 1 that are counted and transferred on the belt conveyor 9 advance in the direction of the arrow in FIG. 3 and are stopped by a stopper 10 at the final end.

At this time, the product 1 is placed under the L-shaped attachment 12.

Next, as shown in FIGS. 3 and 4 (side view from the direction of arrow B in FIG. 1), an attachment made of a transparent plastic material with a cross-section is attached so as to proceed in a direction perpendicular to the direction of movement of the belt conveyor 9. The chain conveyor 11, on which the chain conveyors 12 are attached at predetermined intervals, begins to move intermittently.

The time required for the last product 1 to be counted to catch up and contact the products arranged on the belt conveyor 9 after it falls onto the bell 1 to conveyor 9 is set by a timer. is arranged to begin intermittent progression.

The belt conveyor 9 continues to move continuously unless the entire apparatus is stopped.

As shown in FIG. 3, the products 1 at the leading end are stopped by a stopper 10 provided close to the belt conveyor 9, and a predetermined number of parallel products 1 are then placed under the attachment 12, and then transferred to the stopper 10 in FIG. Chain conveyor 11 as shown
With intermittent progress, the parallel products 1 leave the E position on the belt 9, move onto the support plate 14, move to the F position, and move onto the chain conveyor 1.
1 stops.

At the same time as the intermittent progress of chain conveyor 11 starts, the next product 1
A feeder 3. Belt conveyor4. and the chain conveyor 5 starts operating again,
As described above, the products 1 are dropped one by one onto the belt conveyor 9.

The parallel product 1 stopped at the F position is transferred to the next chain conveyor 11
Goes to the G position with intermittent progression and stops, then moves to G with the next intermittent progression.
When the parallel products 1 move from the position to the H position, they fall onto the receiving plate 19 while remaining parallel to each other below the support plate 14, and when viewed from above, they are surrounded by a protruding metal fitting 15 that is exactly U-shaped, and the bottom surface of the parallel products 1 is At the same time as being supported by the receiving plate 19, the protruding metal fitting 15 moves forward,
The receiving plate 19 moves backward.

The protruding metal fitting 15 is an arm 16' extending from the slide bearing 16.
A receiving plate 19 is mounted on the bearing 20 and slides the shaft 17 fixed to the brackets 23 and 24 in the direction of the arrow C2D, that is, left and right in the figure, by the operation of the air cylinder 18. 17 is slid in the same direction as the shaft 17, that is, left and right, by the operation of the air cylinder 22.

A predetermined number of parallel products 1 that have fallen so as to be surrounded by the protruding metal fittings 15 having a U-shaped frame are once supported by the receiving plate 19, and at the same time the protruding metal fittings 15 move forward in the direction of arrow C.
9 is a box 2 that retreats in the direction of the arrow and is placed with its tip facing downwards.
The projecting metal fitting 15 pushes out the parallel products 1, slides them on the receiving plate 19, and inserts them into the box 2 in parallel to supply them in an aligned manner.

The box 2 is placed on a fixed stand, but in order to automate this part as well, the box 2 may be placed on a belt conveyor (not shown) that moves intermittently.

When the parallel products 1 are placed in the box 2 as shown in FIG. 2, the protruding metal fittings 15 move back in the direction of the arrow, while the receiving plate 19 moves forward in the direction of the arrow C and is stopped at a predetermined position as shown in FIG. Then, the parallel products 1 arranged under the next attachment 12 are conveyed intermittently by the chain conveyor 11, fall into the U-shaped protruding metal fitting 15, and are supported by the receiving plate 19, as described above. , each is activated again to lock the parallel products into the next transported box 2.

As described above, the products 1 placed in the feeder 3 in a misaligned manner are placed one by one into the gap 7 of the chain conveyor 5 and fall onto the belt conveyor 9 one after another, and with the help of the photocells 8 and 8', the products 1 are placed into the counting device. When the predetermined number is reached, the feeder 3. Belt conveyor4. The chain conveyor 5 automatically stops, and the parallel products 1 on the belt conveyor 9 move intermittently on the support plate 14 while remaining parallel due to the intermittent progress of the attachment 12, fall from the end of the support plate 14, and engage the protruding metal fittings 15 and the receivers. The bar-shaped products 1 are supported and held by the plate 19, and the bar-shaped products 1 are aligned and fed one after another into the box 2 placed on the stand 25 by repeating various operations in which they are placed in the box 2 in parallel by advancing and retreating alternately. This allows bar-shaped products to be aligned in the same direction and automatically packaged uniformly in a predetermined number of boxes without using human hands, contributing to efficiency and labor savings.
