Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for accurately collecting stick-shaped food packages packaged in sticks such as stick sugar, stick-shaped package seasoning, and other stick-shaped package sweeteners in an arbitrary predetermined number.
[0002]
[Prior art]
Taking stick sugar as an example of stick-shaped food packages, powder sugar is divided into a predetermined amount (for example, 1 to 10 g arbitrary weight) and filled in a rod-shaped packaging bag while being fed side by side by a conveyor. The worker A accumulates an arbitrary predetermined number (for example, an arbitrary number of 10 to 300), and then a bundle of stick sugars accumulated by different workers B is a second packaging bag in the form of a product. I was working on packing. Since there are hundreds of different types of products with different sugar weights and number of packages in the sticks, workers need to be quick and accurate. In addition, it is difficult to automate because the collection work is performed according to the specifications with different number of packages and weight.
[0003]
[Problems to be solved by the invention]
Therefore, in the present invention, the accumulation and measurement in the pre-process of the work of packing the stick-shaped food package packaged in a stick shape such as stick sugar into the product packaging bag is automated.
[0004]
[Means for Solving the Problems]
As a result of examining the above problems, a counting means (counter sensor) is provided for each of a plurality of conveyors provided in a parallel state moving in the same direction as the longitudinal direction of the stick-shaped food package, and a plurality of counters are provided downstream of each conveyor. An apparatus for stacking stick-shaped food packages, provided with a small-sized alignment means for aligning and holding the stick-shaped food package, and provided with a receiving tray for a collection dish for storing a large number of stick-shaped food packages under the small-sized alignment means; did. As the counting means, an optical sensor is preferable, and its structure is combined control with a counter.
Small edge alignment means means that all the stick food packagings (for example, 4 to 10) are aligned in the same direction, and aligned to the subsequent stacking pan (the direction and front and back positions are aligned). It means enabling migration.
[0005]
As the small edge aligning means, a plurality of guide plates arranged in parallel or narrowly below may be provided to forcibly align the stick-shaped food packaging bodies in the same direction so as to enable the transition to a later stacking dish. Although considered, stick-shaped food provided with a cross-section C-type receiving cylinder that can rotate at least downstream of each conveyor as a small-mouth aligning means, and provided with a small-mouthed collection basket whose bottom is an open / close door. This is an apparatus for stacking packages, and if a tray tray for receiving a large number of stick-shaped food packages is provided below the small-sized stacking basket, all stick-shaped food packages are forcibly identical. It can be aligned in the direction.
[0006]
According to this apparatus, the stick-shaped food package supplied to each of the plurality of conveyors is counted by the counting means, and then held in a C-shaped receiving cylinder having a split slot in a part of the cylinder. When the C-shaped cross-section cylinder is rotated, the stick-shaped food packaging body falls from the split to the small-mouthed collecting basket when the split comes down. As a result, it became possible to align the stick-shaped food package on the small-mouthed basket. When a predetermined number of stick-shaped food packagings accumulate on the small-mouthed basket, the bottom door is opened and taken out downward.
[0007]
By shifting the mounting position of the counting means between the conveyors arranged in parallel, even if the stick-shaped food packaging is supplied to each conveyor at the same time, the counting of each counting means is shifted in time. This eliminates miscounting.
[0008]
The longitudinal direction of the stick-shaped food package is the same as the moving direction of the conveyor on which it is placed (the moving direction of the conveyor is the same as the longitudinal direction of the stick-shaped food package on the conveyor), that is, the stick-shaped food package is vertically Therefore, the detection length (time) by the counting means is long, and the amount of information to be detected is large. The bar-shaped packaging bags can be collected by color and pattern, and can be stored in the final product packaging bag by color and pattern.
[0009]
A height adjusting means is provided at least on the downstream side of each conveyor. Sticky food packages have different inertias when dropped depending on their weight. In particular, stick sugar can jump when it is heavy. Therefore, the height of the conveyor can be adjusted by the weight of the stick-shaped food package.
[0010]
A predetermined number of stick-shaped food packaging bodies are accommodated in a stacking dish, and weighing means can be weighed by providing weighing means (load cells) at or near the cradle. The accuracy of product packaging is improved by both counting by the counting means and weighing by the weighing means.
[0011]
Each conveyor is provided with a stopper capable of stopping the movement of the stick-shaped food package toward the stacking part when necessary. When it is determined that the stick-shaped food packaging body counted by the counting means is close to the predetermined number when it is sent to the predetermined number accumulation unit side, when only the number that is insufficient for the predetermined number is passed to the accumulation unit side, A part of the stopper is lowered to stop the movement of the stick-shaped food package toward the stacking part. In addition, it is possible to divide and wrap packages with different appearances of stick-shaped food packaging bodies, or conversely, and to provide a stopper is useful.
[0012]
Defective product pushing means is provided at or near the receiving tray of the collecting tray that contains the stick-shaped food packaging body. When a defective packaging product is detected by the weighing means, the collecting dish is automatically collected together with the stick-shaped food packaging body. I tried to remove it.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a front view of an apparatus for collecting stick-shaped food packaging bodies according to the present invention, FIG. 2 is a side view of the apparatus, and FIG. 3 is a plan view of the apparatus. In this apparatus, six conveyors 3 are provided in parallel from the supply unit 1 side of the stick-shaped food package toward the stacking unit 2. Each conveyor 3 has a structure in which a chain conveyor is provided in the groove, and the longitudinal direction of the stick-shaped food package is the same as the moving direction of the conveyor 3. On the downstream side of each conveyor, an extendable leg with a stopper is provided as a height adjustment means 20 so that the stick-like food package can be adjusted to an appropriate height that is difficult to jump when packaging, although it is easy to jump when falling like sugar. Yes.
[0014]
The counting means 4 is provided on each of the plurality of conveyors 3. The counting means 4 detects the stick-shaped food package 5 carried by each conveyor 3 and counts the number of passing pieces. Each conveyor 3 has a stopper 6 that can stop the movement of the stick-shaped food package toward the stacking portion 2 when necessary. The stopper 6 has a structure in which a stopper plate that can approach and separate from each conveyor 3 is advanced and retracted by a cylinder. When it is determined that the stick-shaped food packaging 5 counted by the counting means 4 is close to the predetermined number when it is sent to the predetermined number stacking unit 2 side, it passes through the stacking unit 2 side by an insufficient number of the predetermined number In order to stop the movement, a part of the stoppers 6 is lowered to stop the movement of the stick-shaped food package toward the stacking portion 2 side.
[0015]
For example, in the case of packaging of 100 pieces, when 16 pieces are carried by each of the six conveyors 3, a total of 96 pieces are accumulated on the accumulation unit 2 side. Since only the remaining four are insufficient, the movement of the stick-shaped food package is stopped by the stoppers 6 of the two conveyors 3. As a result, four stick-like food packages are replenished, and 100-pack can be packaged.
[0016]
4 is a side view of the stacking unit 2, FIG. 5 is a front view, and FIG. 6 is a plan view. On the stacking unit 2 side, an open cross-sectional C-shaped receiving cylinder 7 serving as a fore edge aligning means 21 is provided in the vicinity of the end of the path of the stick-shaped food package sent by each conveyor 3. The cross-section C-type receiving cylinder 7 is intended to arrange the direction cleanly so that the stick-shaped food fed by the conveyor 3 suddenly falls downward and does not bounce or accumulate randomly, as shown in FIG. As shown in FIG. 7, when it is rotated as shown in FIG. 7, the stick-shaped food packaging body falls from the cut 7a when the cut 7a is turned down. I am doing so. There is a motor 8 that rotates when the stick-shaped food package enters the cross-section C-type receiving cylinder 7 for rotation, and a crank mechanism 9 that rotates the holding shaft of the cross-section C-type receiving cylinder 7 by the motor 8. When the counting means 4 confirms that the stick-like food package has entered the cross-section C-type receiving cylinder 7, the dividing slot 7a is simultaneously rotated downward.
[0017]
At this time, if there is no sticky food package in any of the cross-section C-type receiving cylinders 7, it is known by the counting means 4. The stick-shaped food package is accommodated in the C-shaped receiving cylinder 7 in section. This is also done by linking with the stopper 6 on the conveyor 3. Below the C-shaped receptacle in cross section, there is provided a small mouth collecting rod 11 which also has an opening / closing door 10 on the bottom as a small edge aligning means 21. A small number (usually 10 to 20) of stick-shaped food packaging bodies are once stored in the small-mouthed basket 11. Although the opening and closing of the opening / closing door 10 on the bottom surface is omitted in the drawing, six opening / closing doors 10 are simultaneously opened by one cylinder. Therefore, the open / close door 10 has a hinge 10a on one edge, and an open / close rod 10b abuts on the middle of the bottom surface.
[0018]
As shown in FIGS. 1 to 3, a receiving tray 13 for a collecting tray 12 that can accommodate a large number of stick-shaped food packaging bodies is provided below the small-mouthed collecting basket 11. The stacking tray 12 is placed on a receiving tray 13 and can be moved when a predetermined number of stick-shaped food packaging bodies are dropped and stacked from the small stacking basket 11. When an abnormal situation occurs in which the number of stick-shaped food packages does not reach the predetermined number, a discharge cylinder 14 is provided on the side of the main body of the device, and the stick-shaped food packages are discharged to the side together with the stacking tray 12 in the event of an abnormality. be able to.
[0019]
A load cell is provided as a weighing means 15 in the tray 13 for receiving the stick-shaped food package, and the collected stick-shaped food package is accurately measured. The bag-packing operation of the stick-like food package accumulated by the apparatus can be performed manually or can be automated by providing a bag-packing apparatus at the side of the apparatus. In consideration of workability in the case of manual work, a work table 16 whose height is adjustable is provided.
[0020]
【The invention's effect】
According to the present invention, it is possible to automate a predetermined number of stacking operations by hand. Even when products with various specifications such as stick sugar with different weights and number of packages are manufactured in a wide range of several hundred types, the integration of the device of the present invention for arbitrary packaging into products of various specifications Made possible. It is possible to avoid an abnormality in the number of packages that are likely to occur during manual accumulation work, and to reduce the number of personnel and improve the efficiency.
