Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a device that automatically collects and boxes a large number of individually packaged products.

(Prior Art) When packaging and transporting a large number of individually packaged products, conventionally, manual work was required to assemble the products and pack them into boxes, which hindered automation and the overall process.

Therefore, there is a known box packing device that pushes out multiple individually packaged products transported by a conveyor onto a loading platform, lowers the loading platform one by one, and packs the products into cardboard boxes using an appropriate method (Jikkosho).
54-44057)), there is no means to align the individual packaged products on the conveyor, and the individual packaged products are extruded while being lined up in a flat shape, so the number of products extruded at one time is 2 to 3 or 3 to 4. However, there are disadvantages in that it requires multiple extrusion operations to pack one box.

It is also known that individually packaged products stacked in multiple stages in a row are pushed out using a pusher, sandwiched between partition plates, and transported to another location using a carrier for packaging work (Japanese Patent Laid-Open No. 59-134128 (Refer to the Japanese Patent Publication No. 2003-111000), not only does it require an alignment chute for arranging the individually packaged products in the preceding stage, but it also requires a separate boxing operation, which is complicated.

Furthermore, the individually packaged products conveyed by the first conveyor are received one by one by a second conveyor having a partition plate, and sent one by one into the receiving frame via a chute,
There is also a known system in which after multiple receiving frames are full, they are pushed out into the box using a pusher (see Japanese Patent Publication No. 30597/1983), but this not only requires two types of conveyors, but also requires only one conveyor. Since it involves the step of feeding the boxes one by one, the boxing process is time consuming and inefficient.

(Problems to be Solved by the Invention) The object of the present invention is to improve the problems of the prior art, and to perform the operations from manufacturing to packaging of a large number of individually packaged products online.

In other words, the individual packaged products conveyed horizontally on the first conveyor are transferred to the second conveyor, and at the same time, the orientation of the individual packaged products is changed so that they are aligned vertically. The object to be solved is to make it possible to sequentially push packaged products into multi-layer boxes to form multiple rows of multi-stage boxes, change the position of the multi-layer boxes, and pack the individually packaged products of multiple rows of multi-layer boxes at once.

(Means for Solving the Problems of the Invention) A conveyor with pins 1 on the surface of which pins 1a are arranged in rows at regular intervals and conveys a plurality of individual products A at intervals in a horizontal state; A rotatable stacking wheel 2 that faces the discharge side and receives the individual packaged products in a horizontal state and discharges them in a vertical state, a sloped portion 3a of the stacking wheel 2 facing the discharge side, and a slope portion 3a that is continuous with the sloped portion 3a. Slope conveyors 3 each having a flat portion 3b and conveying the individual packaged products in a vertically aligned state are connected to each other. A drive device 5 is provided to drive the cross-feed plate 4 in a direction perpendicular to the running direction of the conveyor 3 to push the individual products to the opposite side, and a stacking device 6 is provided on the other side of the slope conveyor 3. and the stacking device 6
is driven by a motor 7 and an indexing device 8
90° to the direction of rotation around a central axis supported by
The indexing device 8 is provided with four multi-layered boxes 9 arranged at intervals, and the indexing device 8 is supported by a vertical movement drive device 10 so as to be vertically movable. At a position corresponding to the position where the multilayer box 9 is rotated by 90 degrees from the stacking position of the crossfeed board 4, the individually packaged products in the multilayer box 9 are all pushed out to the opposite side and stored in the box set in that part. A pushing device 11 is provided, and the stacking device 6 includes:
When the uppermost stage of one of the four multilayer boxes 9 faces the crossfeed plate 4, the one at the front stage in the rotational direction is intermittently driven to rotate by the motor 7 so that it faces the pushing device 11. In addition, the pushing device 11 is characterized in that it is operable only when the indexing device 8 is lowered to the lowest position by the vertical drive device 10.

(Example) An example will be described below with reference to the drawings. 1 is a conveyor with pins on the surface of which pins 1a are arranged in rows at regular intervals, and conveys individual products A to the next process; 2 is rotatable so as to face the travel path of the conveyor with pins 1; The stacking wheel is installed horizontally on the stacking wheel, and has a plurality of grooves 2a evenly distributed on the circumference. 3 is a slope conveyor facing the jumping side of the stacking wheel 2, and its shape includes a slope section 3a for lifting the individual packaged products upwards, and a slope section 3a for lifting the individually packaged products A continuously on this slope section. For example, a phototube (not shown) is provided on the side of the slope portion 3a of the slope conveyor 3 to detect the individual packaging of individual products placed on the slope conveyor 3. ing. Further, on the side of the flat portion 3b of the slope conveyor 3, there is a cross feed plate 4 for horizontally feeding the individually packaged products lined up on the flat portion 3b.
and an air cylinder 5 for driving this, and on the other side, a multilayer box 9 constituting a stacking device 6 faces the crossfeed plate 4. The individually packaged products are then stored in the box.

The stacking device 6 includes a main body frame 6a that is driven by an index motor 7 and supported by a central shaft that is rotatably supported by an index device 8, and four sets of multilayer boxes 9 arranged around the main body frame 6a.
A driving cylinder 10 for vertically moving the stacking device 6 is provided below the indexing device 8.

When each of the four sets of multilayer boxes 9 is in a horizontal state, a plurality of partition plates 9a are disposed inside the box in the horizontal direction to form a product storage in multiple stages.
A comb-shaped pushing device 11 is provided above the flat portion 3b of the slope conveyor 3 for pushing out the individually packaged products stored in the multilayer box 9 all at once and pushing them into a cardboard box 12 set on the entire surface thereof.

(Operation of the invention) The configuration of the invention is as described above, and the operation will be explained next.

Individually packaged product A manufactured by a predetermined manufacturing process
are conveyed in a horizontal state at regular intervals in the direction a by a conveyor 1 with pins on the surface of which pins 1a are arranged in rows at regular intervals.

When it is brought to the position of stacking wheel 2,
The product A is scooped up into the groove 2a of the rotating stacking wheel 2 and discharged onto a slope conveyor 3 having an upward slope. As a result, the individually packaged products A, which had been held horizontally at intervals on the pin-equipped conveyor 1, are reoriented and aligned so as to be perpendicular to the conveyor surface of the slope conveyor 3.

That is, when the individual packaged products A, which are conveyed by the conveyor 1 with pins in a horizontal state (horizontal state) with respect to the conveyor surface, are carried to a position facing the stacking wheel 2, It is scooped up by the structure 2a, and as the stacking wheel 2 rotates, its direction gradually changes to the vertical direction, and at the discharge end it becomes perpendicular to the conveyor surface of the slope conveyor 3 (vertical state). It is discharged and placed on the slope conveyor 3. (See Figure 2) In this way, the individual packaged products A are placed from the stacking wheel 2 onto the slope conveyor 3.
As the stacking wheel 2 rotates, it moves forward by being successively pushed aside by the peripheral edge (mountain) 2b located forward in the direction of rotation of the succeeding groove 2a. The subsequent individually packaged products A held in the next groove 2a slide into the space, and are sequentially placed and aligned on the slope section 3a of the slope conveyor 3.

When a predetermined number of product groups are placed and aligned on the slope section 3a of the slope conveyor 3, the driving device (not shown) of the slope conveyor 3 is driven to start traveling, and the product group is placed on the slope section 3b of the slope conveyor 3. When the slope conveyor 3 is reached, a stopper (not shown) stops the slope conveyor 3.
stops, and each individual packaged product A is held in vertical alignment on the flat portion 3a.

Next, when the crossfeed plate 4 on the side of the flat part 3b of the slope conveyor 3 is operated, the products are transported all at once to the opposite side of the conveyor, and the products are stored in the uppermost stage of the multilayer box 9 facing this position. Pushed into storage. When this operation is completed, the stacking device 6 is raised by one level by the vertical movement drive device 10 of the indexing device 8, and the products are stored in the second product storage from the top of the multilayer box 9 by the same operation as described above. . Following the same steps,
The products are stored in the lower product storage in sequence.

When the products have been stored in one set of multilayer boxes 9 in this way, the indexing device 8 is started and the index motor 7 moves the main body frame supporting the four sets of multilayer boxes 9 counterclockwise. Rotate 90°. At the same time, the vertical drive device 10 is driven to lower the index device 8,
Lower the stacking device 6 to the lowest position.

By this operation, the partition plate 9a in the multilayer box 9 containing the product is inevitably oriented vertically. In this state, the comb-shaped pushing device 11 is operated to push out the products in the product storage in the vertical position all at once to the opposite side, and the products are kept at that position with the lid open by an appropriate device (not shown). Push it into a certain cardboard box 12.

If necessary, the cardboard box filled with the product is erected by appropriate means and transported to a subsequent process.

While the product is being packed into boxes, the multilayer box 9' located at the bottom in the figure, which has been rotated counterclockwise, is held in a horizontal state and is positioned opposite to the crossfeed plate 4, Therefore, the operation of filling the uppermost stage of the multilayer box 9', which does not contain any products, with products can be carried out at any time, regardless of other operations.

By detachably attaching the multilayer box 9 to the main body 6a to which the indexing device 8 is attached, it is possible to use a box of a desired number of stages or size, and it is possible to store the number of products according to the size of the cardboard box. If possible, and if a cardboard box of a size corresponding to an appropriate number of shelves is set, it can be replaced with a multi-layer box of the same size, etc., making it possible to store various numbers of products.

(Effects of the invention) Since the invention has the structure and function described above, it is possible to change the direction of individual packaged products conveyed in a horizontal state on the first conveyor at the same time as transferring them to the second conveyor. This makes it possible to arrange the individually packaged products in multiple rows through multi-layer boxes and pack them all at once, streamlining the packing work.
Extremely effective for automation. In addition, in the previous process, the number of products is counted and detected by the speed at which the products are introduced from the conveyor with pins or by the detection device, and each drive device is controlled based on the signal, allowing for quick and continuous boxing work without waste. It became possible.
