Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product which is randomly supplied, such as a packaged product of sugar or candy in a small bag, a packaged product such as a pouch containing a retort food, or any other product having an indefinite shape. The present invention relates to a device for supplying and feeding conveyed objects, which enables automatic accumulation and packaging by a well-known accumulation and packaging machine without the need for directly connecting and interlocking the body with the device in the previous step.

[0002]

2. Description of the Related Art Conventionally, the problems to be solved by the invention
When a predetermined number of packaged objects, such as sugar and candy, which are packaged in small bags with a film, are accumulated and packaged, the shape of the packaging bag will change once pooled in the so-called "press-and-press" state. Since it is difficult to separate and supply one by one, it is directly connected to the device in the previous process (packaging machine for sachets) and linked with the packaging machine using a special collecting and feeding device, or it is collected manually. Needed to be supplied.

In particular, the pouch 1 containing the retort food product is individually and randomly transported to the transport device 50 in the subsequent process after the sterilization process and the metal inspection process in the preceding process shown in FIG. When they were pooled in the "press-and-press" state above, the pitches became indeterminate due to overlapping, making it difficult to automatically stack and pack multiple pieces.

On the other hand, if the object to be conveyed is solid (for example, if the object to be accommodated is accommodated in a case such as a box having rigidity), it is difficult to be deformed, and therefore, "press and hold".
It becomes possible to pool in a state, and it is possible to take out a predetermined number and easily perform automatic stacking packaging.

The present invention has been made in view of the above-mentioned problems of the prior art. Even if the transported object is a package which is easily packaged, it is easy to deform the transported object once. By accumulating in a bucket having, it can be handled like a transported object that is not easily deformed, and it is not necessary to directly connect and interlock with the device in the previous step, and it is possible to perform integrated packaging using a well-known accumulation packaging device. The task is to do.

[0006]

In order to solve the above-mentioned problems, the present invention has been made as an integrated supply device for conveying objects, which is characterized by a conveying device 2 for individually conveying the conveyed objects 1. A transport device 3 for accelerating and decelerating the transported object 1 supplied from the transport device 2 to a predetermined speed, a bucket 5 for receiving a predetermined number of the transported objects 1, and a transport capable of transporting the bucket 5 by sliding contact. Means 20, a fixed position stopping means 9 for releasably stopping the bucket 5 at the receiving position A of the transferred object 1, and a predetermined number of transferred objects 1 in the bucket 5A.
Second fixed position stopping means 10 for releasably stopping the bucket 5A at the discharge position B so as to supply
To be equipped with.

Then, the objects to be transferred 1 which are transferred at a predetermined speed are individually supplied to the bucket 5 at the receiving position A by the transfer device 3. At this time, the bucket 5 has the transport means 2
Since it is in sliding contact with 0, the transport means 20 allows the relative movement of the bucket 5.

Further, the first fixed position stopping means 9 releases the stop of the bucket 5 when a predetermined number of objects to be transferred 1 are transferred to the bucket 5, so that the bucket 5 is transferred to the transferring means 2.
It is conveyed by the conveying means 20 due to the frictional resistance with 0.

Bucket 5 for accommodating a plurality of objects 1 to be conveyed
However, when reaching the discharge position B, the second fixed position stopping means 10
Since the bucket 5 is stopped, the transported object 1 in the bucket 5 can be automatically supplied to the supply conveyor 8.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. 1 to 4 show an embodiment of the present invention. In the integrated feeding device of the present invention, a transported object 1 that cannot be pooled in a "press-and-press" state is randomly supplied from a previous process. There is.

The transported object 1 is a granular material such as sugar or candy, a powder or a small article 1a packaged in a small bag (see FIG. 4 (a)), and a packaged body in which a thin packaged object is packaged (see FIG. 4). Four
(See (b)) or a package such as a pouch containing retort food (see FIG. 4 (c)), or any other indefinite shape. In addition, the pre-process refers to a process (including a sterilization process and a metal inspection process) in which the object to be packaged, for example, candies are packaged in a pouch packaging machine, and retort foods and the like are pouch-packaged.

The transport device 2 (belt conveyor, etc.) for transporting the transported object 1 is operated at a higher speed than the pouch packaging machine in the previous step. Therefore, the transport device 2 is
Each transported object 1 supplied from a pouch packaging machine or the like can be sent to the acceleration / deceleration transportation device 3 at appropriate intervals.
The acceleration / deceleration transportation device 3 is capable of decelerating or accelerating each transported object 1 so as to be transported at a predetermined speed.

A transport device 6 for transporting a plurality of buckets 5 is provided at the downstream end of the acceleration / deceleration transport device 3 in a direction orthogonal to the transport direction of the transported object 1 of the acceleration / deceleration transport device 3. There is. The transport device 6 is, for example, an endless transport belt 20 as a transport means wound around a pair of pulleys 21a and 21b so as to be rotatably rotatable. Examples of the transport belt 20 include a plurality of belt members made of synthetic resin connected to each other.

Each bucket 5 has a bottom wall 5a slidably contacting the surface of the conveyor belt 20, a front and rear wall 5b,
5c, and both side surfaces and the upper surface are opened. On both sides of the bottom wall portion 5a, the conveyor belt 20 is formed by the bottom wall portion 5a.
A roller 22 is provided as a locking unit that rolls the back surface of the conveyor belt 20 so as to sandwich the roller 22. Each bucket 5 is not fixed to the conveyor belt 20, but is held by sliding contact by the bottom wall portion 5a or rolling contact by each roller 22.

Between the upper belt portion 20a and the lower belt portion 20b of the transport belt 20, each bucket 5 is releasably stopped and held at a predetermined position (reception position) A at the downstream end of the acceleration / deceleration transport device 3. A fixed position stopping means 9 is provided for this purpose. The first fixed position stopping means 9 is provided so as to be vertically swingable about a fulcrum 25 so that the hook body 24 is releasably engaged with the downstream side of the roller 22 of each bucket 5. Is.

A second fixed position stopping means 10 for stopping and holding the bucket 5 at the discharge position B for supplying the bucket 5 to the supply conveyor device 8 is provided at a position downstream of the fixed position stopping means 9. The fixed position stopping means 10 also includes a hook body 28 that is vertically swingable around a fulcrum 27, like the fixed position stopping means 9.

Further, each of the pulleys 21a and 21b has
An upstream reversing means 12 and a downstream reversing means 11 for engaging the rollers 22 of each bucket 5 from the rear and reversing the bucket 5 are provided so as to rotate integrally with the respective pulleys 21a and 21b.

Reference numeral 13 is a detection sensor for detecting the object to be packaged 1 which is put into the bucket 5 from the acceleration / deceleration transportation device 3. 14 is a bucket (actual bucket) 5A into which a predetermined number of accumulated objects 1 are loaded at the discharge position B.
It is a pool amount minimum detection sensor for detecting a predetermined number of buckets 5 that are brought into contact with each other in a "push-push" state.

Next, the operation of the integrated supply device will be described. First, the transported object 1 processed in the previous step is randomly supplied to the transportation device 2. Since the transfer device 2 is operated at a speed higher than that in the previous step, the transferred objects 1 are individually sent to the acceleration / deceleration transfer device 3 at appropriate intervals.

At the receiving position A at the downstream end of the acceleration / deceleration transport device 3, the bucket 5 is stopped and held by the first fixed position stop means 9. Since the bucket 5 is not fixed to the transport belt 20 of the transport device 6 and is held so as to slide or make rolling contact, the upper belt portion 20a of the transport belt 20 has a bottom wall of the bucket 5 that is stopped. Part 5a
It is circulating and rotating while sliding. When the bucket 5 is stopped, the transported object 1 is fed into the bucket 5 at a high speed by the acceleration / deceleration transportation device 3.

When a predetermined number of accumulated objects 1 are loaded, the first fixed position stopping means 9 releases the engagement of the roller 22 of the bucket 5 by swinging the hook body 24 thereof downward. , The actual bucket 5A is opened. The actual bucket 5A is transported forward by frictional resistance due to contact with the belt of the transport device 6. It should be noted that the transported object 1 is fed from both sides of the actual bucket 5A.
It is preferable to provide a guide body (not shown) or the like on the side of the transporting device 6 so as not to accidentally fall off.

At the same time that the actual bucket 5A is conveyed, the next empty bucket 5 that has stopped by contacting the actual bucket 5A also advances due to frictional resistance, and the hook body 24 of the first fixed position stopping means 9 moves. Since it swings upward and engages with the roller 22 of the bucket 5, the next empty bucket 5 is stopped and held at the receiving position A.

The predetermined accumulation number of the transported objects 1 is detected and integrated by the detection sensor 13. When the final number is detected, the acceleration / deceleration transportation device 3 is in the deceleration operation state, the actual bucket 5A passes, and the next empty bucket 5 arrives at the receiving position A until the next transported object 1 arrives. Is held so that it is not turned on.

When the next transported object 1 having the first accumulated number is detected by the detection sensor 13, the acceleration / deceleration transportation device 3 is in an accelerating operation state, and thereafter, the empty bucket 5 of the transported object 1 is similarly moved. Will be repeated.

The actual bucket 5A is stopped and held at the discharging position B by the second fixed position stopping means 10. Further, when the required minimum number of actual buckets 5A are pooled in the "press-and-press" state, the minimum pool amount detection sensor 14 detects the final actual bucket 5A. Pool amount minimum detection sensor 1
In response to the signal of 4, the supply conveyor 8 of the stacking packaging machine is activated, and at the same time, the charging device 7 (pusher, overhead conveyor, etc.) is operated, and the plurality of conveyed objects 1 (collected products 4) in the actual bucket 5A are taken out. , To the supply conveyor 8.

The bucket 5 which has been emptied by taking out the accumulated product 4 is released by releasing the engagement of the second fixed position stopping means 10, and is advanced again by the carrying device 6. At the same time, the next actual bucket 5A also advances, and the next actual bucket 5A is stopped and held at the discharge position B by the second fixed position stopping means 10.

The emptied bucket 5 moves to the lower belt portion 20b of the conveyor 20 because the downstream side inverting means 11 engages with the roller 22, and further, the upstream side inverting means 12 causes the upper belt portion 20a. Go to and empty bucket 5
, And is pooled in the "press-and-press" state before the receiving position A. As described above, the automatic accumulation operation state is continued.

By the stacking and feeding device of the present embodiment, even the transported objects 1 which are difficult to be pooled in the "press-down" state, such as the transported objects having an indefinite shape, are temporarily accumulated in the bucket 5, Since it can be handled like a solid transported object, it is possible to carry out integrated packaging using a normal integrated packaging machine without the need for direct connection and interlocking with the device in the previous step (packaging machine for small bags).

The present invention is not limited to the above-mentioned embodiment, and, for example, the shape and size of the bucket are not particularly limited, and can be appropriately determined depending on the type of the transported object and the number of accommodated objects. is there.

[0030]

Since the present invention is constructed as described above,
Even if it is difficult to pool in a "press-and-press" state, such as an indefinite transferred object, by accumulating a plurality of these transferred objects in the bucket 5 once, It can be handled like a carrier.
As a result, there is an advantage that it is possible to automatically and efficiently carry out integrated packaging using a normal integrated packaging machine without directly interlocking with the apparatus of the previous step, and to reduce the cost required for a series of packaging steps.
