Description

[0001]
BACKGROUND OF THE INVENTION
The present invention provides a device for pre-processing, such as a package of sugar or candy packed in a small bag, a packaged object such as a pouch containing a retort food, or another object to be randomly supplied, such as an undefined shape. The present invention relates to a stacking and feeding apparatus for a transported body that can be stacked and packed automatically by a well-known stacking and packaging machine without having to be directly coupled to the transporting apparatus.
[0002]
[Prior art and problems to be solved by the invention]
Conventionally, when a predetermined number of packages to be transported, which are formed by packing sugar or candy in a small bag with a film or the like, is accumulated and packed, once the pool is placed in a so-called “press and hold” state, Because it is difficult to separate and supply one by one due to changes in shape, it is directly connected to the previous process device (packaging machine for small bags) and linked with the integrated packaging machine using a special integrated supply device, or by hand It was necessary to collect and supply.
[0003]
In particular, the pouch 1 containing retort food is individually and randomly transported to the transport device 50 in the subsequent process after passing through the sterilization treatment process and the metal inspection process in the previous process shown in FIG. When pooled in the “press and press” state, they overlap and the pitch becomes indeterminate, making it difficult to automatically pack a plurality.
[0004]
On the other hand, if the object to be transported is solid (for example, when the object to be stored is housed in a case such as a rigid box), it is difficult to deform, so it can be pooled in the “press and hold” state. Thus, automatic collection and packaging can be easily performed by taking out a predetermined number.
[0005]
The present invention has been made in view of the conventional problems as described above, and even if the transported body is easily deformed, such as a small packaged package, the transported body is once a rigid bucket. It is possible to handle in the same way as a to-be-conveyed object that is difficult to be deformed, so that it is not necessary to link directly to the previous process device, and it is possible to perform integrated packaging using a known integrated packaging device. Let it be an issue.
[0006]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention has been made as an apparatus for collecting and supplying a body to be transported. The feature of the present invention is that a transport apparatus 2 that individually transports the transported body 1 and the transport apparatus 2 supply it. A transport device 3 that accelerates or decelerates the transported body 1 to a predetermined speed, a bucket 5 that receives a predetermined number of transported bodies 1, transport means 20 that can transport the bucket 5 by sliding contact, and the bucket 5 The first fixed position stop means 9 for releasably stopping at the receiving position A of the transported body 1 and the bucket 5A at the discharge position B in order to supply a predetermined number of transported bodies 1 in the bucket 5A to the supply conveyor 8. The second fixed position stop means 10 that is releasably stopped at the first position, the upstream inversion means 12 that engages with the bucket 5A and inverts the bucket 5A on the upstream side and the downstream side of the transport means 20, respectively, and the downstream inversion means. 11 and For example,
The conveying means 20 is composed of an endless conveying belt that rolls, and the first fixed position stopping means 9 and the second fixed position stopping means 10 are formed by an upper belt portion 20a and a lower belt portion 20b of the conveying belt 20, respectively. It is provided with hook bodies 24 and 28 which are provided in the middle and which are respectively provided on the bucket 5A and engage with a roller 22 which rolls on the back surface of the conveying means 20 and can swing up and down .
[0007]
And the to-be-conveyed body 1 conveyed by the predetermined speed by the conveying apparatus 3 is supplied to the bucket 5 in the receiving position A individually. At this time, since the bucket 5 is in sliding contact with the transporting unit 20, the transporting unit 20 allows the relative movement of the bucket 5.
[0008]
Furthermore, the first fixed position stop means 9 releases the stop of the bucket 5 when a predetermined number of the transported bodies 1 are delivered to the bucket 5, so that the bucket 5 is subjected to friction resistance with the transport means 20. It is transported by the transport means 20.
[0009]
When the bucket 5 that accommodates the plurality of transported bodies 1 reaches the discharge position B, the second fixed position stop means 10 stops the bucket 5 so that the transported body 1 in the bucket 5 is fed to the supply conveyor. 8 can be automatically supplied.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
1 to 4 show an embodiment of the present invention. In the integrated supply device of the present invention, the transported bodies 1 that cannot be pooled in the “press and press” state are randomly supplied from the previous process. Yes.
[0011]
The transported body 1 includes a granular body such as sugar or candy, a powder or a small article 1a packaged (see FIG. 4 (a)), and a packaged body wrapped with a thin package (FIG. 4 (b)). )) Or a packaging body such as a pouch containing retort food (see FIG. 4 (c)) and other indefinite shapes. In addition, the pre-process refers to a process (including a sterilization process and a metal inspection process) in which the article to be packaged wraps candy or the like with a sachet packaging machine or pouch-wraps retort food or the like.
[0012]
A transport device 2 (a belt conveyor or the like) for transporting the transported body 1 is operated at a higher speed than a sachet packaging machine or the like in the previous process. Accordingly, the transport device 2 can send each transported body 1 supplied from a sachet packaging machine or the like to the acceleration / deceleration transport device 3 at an appropriate interval. The acceleration / deceleration transport device 3 can decelerate or increase the speed so that each transported body 1 can be transported at a predetermined speed.
[0013]
A transport device 6 that transports a plurality of buckets 5 in a direction orthogonal to the transport direction of the transport target 1 of the acceleration / deceleration transport device 3 is provided at an end portion that is a downstream position of the acceleration / deceleration transport device 3. The transport device 6 is, for example, an endless transport belt 20 serving as transport means that is wound around a pair of pulleys 21a and 21b so as to be freely rotatable. The transport belt 20 includes, for example, a belt in which a plurality of belt members made of synthetic resin are connected.
[0014]
Each bucket 5 includes a bottom wall portion 5a that slidably contacts the surface of the conveyor belt 20, and front and rear wall portions 5b and 5c. Both side surfaces and an upper surface are opened. On both sides of the bottom wall 5a, rollers 22 are provided as locking means for rolling the back surface of the conveyor belt 20 so as to sandwich the conveyor belt 20 with the bottom wall 5a. Each bucket 5 is not fixed to the conveyor belt 20 and is held by sliding contact by the bottom wall portion 5 a or rolling contact by each roller 22.
[0015]
Between the upper belt portion 20a and the lower belt portion 20b of the conveyor belt 20, a first stop 5 is provided for releasably stopping and holding each bucket 5 at a predetermined position (receiving position) A at the downstream end of the acceleration / deceleration conveyor device 3. Fixed position stop means 9 is provided. The first fixed position stop means 9 is provided so as to be swingable in the vertical direction around the fulcrum 25 so that the hook body 24 is releasably engaged with the downstream side of the roller 22 of each bucket 5. It is.
[0016]
A second fixed position stop 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 downstream position of the fixed position stop means 9. Similarly to the first fixed position stop means 9, the fixed position stop means 10 also includes a hook body 28 provided so as to be swingable in the vertical direction about the fulcrum 27.
[0017]
The pulleys 21a and 21b are integrally provided with upstream reversing means 12 and downstream reversing means 11 for reversing the bucket 5 by engaging with the rollers 22 of the buckets 5 from the rear together with the pulleys 21a and 21b. It is provided to rotate.
[0018]
Reference numeral 13 denotes a detection sensor for detecting the article 1 to be packaged that is put into the bucket 5 from the acceleration / deceleration conveyance device 3. Reference numeral 14 denotes a pool amount minimum detection sensor for detecting a predetermined number of buckets 5 that are in a “pressed and pressed” state at a discharge position B to a bucket (actual bucket) 5A into which a predetermined number of stacked objects 1 are loaded. is there.
[0019]
Next, the operation of the integrated supply device will be described.
First, the to-be-conveyed body 1 processed in the previous process is supplied to the conveying apparatus 2 at random. Since the transport device 2 is operated at a speed higher than that of the previous step, the transport target 1 is individually sent to the acceleration / deceleration transport device 3 at an appropriate interval.
[0020]
At the receiving position A at the downstream end of the acceleration / deceleration conveyance 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 conveyor belt 20 of the conveyor device 6 and is held so as to be in sliding or rolling contact, the upper belt portion 20a of the conveyor belt 20 is the bottom wall of the bucket 5 that is stopped. Circulating and rotating while sliding on the part 5a. When the bucket 5 is stopped, the transported body 1 is charged and supplied into the bucket 5 at a high speed by the acceleration / deceleration transport device 3.
[0021]
When a predetermined number of stacked transported bodies 1 are loaded, the first fixed position stopping means 9 causes the hook body 24 to swing downward and release the engagement of the roller 22 of the bucket 5. Open 5A. The actual bucket 5 </ b> A is conveyed forward by frictional resistance due to contact with the belt of the conveying device 6. In addition, it is preferable to provide a guide body (not shown) or the like on the transport device 6 side so that the transported body 1 does not accidentally drop off from both sides of the actual bucket 5A.
[0022]
At the same time when the actual bucket 5A is conveyed, the next empty bucket 5 that has stopped in contact with the actual bucket 5A also moves forward due to frictional resistance, and the hook body 24 of the first fixed position stop means 9 swings upward. In order to move and engage the roller 22 of the bucket 5, the next empty bucket 5 is stopped and held at the receiving position A.
[0023]
Note that the predetermined number of stacked objects 1 is detected and integrated by the detection sensor 13. When the final number is detected, the acceleration / deceleration conveyance device 3 enters a decelerating operation state, and the next conveyed object 1 is passed until the actual bucket 5A passes and the next empty bucket 5 arrives at the receiving position A. Is kept from being thrown in.
[0024]
When the next accumulated object 1 to be conveyed is detected by the detection sensor 13, the acceleration / deceleration conveying device 3 enters an acceleration operation state. Hereinafter, the supply of the object 1 to the empty bucket 5 is similarly performed. Will be repeated.
[0025]
The actual bucket 5 </ b> A is stopped and held by the second fixed position stop means 10 at the discharge position B. Further, when the required minimum number of real buckets 5A are pooled in the “press and hold” state, the pool quantity minimum detection sensor 14 detects the last real bucket 5A. In response to the signal from the pool amount minimum detection sensor 14, the supply conveyor 8 of the integrated packaging machine is activated, and at the same time, the input device 7 (pusher, overhead conveyor, etc.) is operated, and a plurality of conveyed objects 1 (integrated products) in the actual bucket 5A. 4) is taken out and put into the supply conveyor 8.
[0026]
The bucket 5 emptied by taking out the accumulated product 4 is released by releasing the engagement of the second fixed position stop means 10, and moves forward again by the transport 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 stop means 10.
[0027]
The emptied bucket 5 moves to the lower belt portion 20b of the conveyor 20 because the downstream reversing means 11 engages the roller 22, and further moves to the upper belt portion 20a by the upstream reversing means 12. Then, it circulates as an empty bucket 5 and is pooled in the “press and hold” state before the receiving position A. As described above, the automatic accumulation operation state is continued.
[0028]
Even if the transported body 1 that is difficult to be pooled in a “press and press” state, such as a transported body having an indefinite shape, is once accumulated in the bucket 5 by the stacking and feeding apparatus of the present embodiment, Since it can be handled in the same way as a transported object, it is possible to perform integrated packaging using a normal integrated packaging machine without the need for direct coupling with the previous process device (packet packaging machine).
[0029]
The present invention is not limited to the above-described embodiment. For example, the shape and size of the bucket are not particularly limited, and can be determined as appropriate depending on the type of the transported object and the number of accommodated objects.
[0030]
【The invention's effect】
Since the present invention is configured as described above, even if the object to be transported is difficult to be pooled in a “pressed and pressed” state, such as a to-be-conveyed object having an indefinite shape, the plurality of objects to be transported are arranged. Once accumulated in the bucket 5, it can be handled in the same manner as a solid transported body. As a result, there is an advantage that efficient and efficient packing can be automatically performed using a normal stacking and packaging machine without requiring direct linkage with the apparatus in the previous process, and the cost required for a series of packing processes can be reduced.
