Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a counting, alignment, and delivery device for transferring transported articles in a fixed quantity and in a fixed posture to the next process.

[Conventional technology]

For example, in packaging equipment for disposable diapers, when packaging a fixed number of disposable diapers in a fixed position, a device is required to arrange and deliver the paper diapers transported by a conveyor or the like to a fixed quantity to the next process, the packaging machine. is necessary.

In addition, lightweight and soft objects such as paper diapers are difficult to handle, and there are inherent technical problems that cannot be predicted on paper.

As a conventional means of arranging this kind of workpieces at a constant rate, as shown in FIG. I was doing it. In addition, this arrangement was performed by arranging several pieces at once instead of arranging them one by one.

[Problem that the invention seeks to solve]

In the conventional alignment described above, because the workpieces are light, irregular in size, and soft, the workpieces are often not aligned as shown in w2, w3, and w4 shown in Fig. 6, and as a result, The count by the counter became inaccurate, and the bagging process in the next process did not go well.

Also, if such misalignment occurs, the automated packaging equipment should be stopped and the misaligned parts corrected, or even if the packaging equipment is not stopped, workers should constantly monitor it. It needed to be corrected, and there were problems in terms of productivity, personnel costs, etc.

In addition, if you use a pusher or the like to forcibly align the workpieces, since the workpieces are soft, the pressing force will not be applied uniformly to the entire workpiece, resulting in irregularities where some workpieces are crushed and others are not. , there is a problem in that the product value is significantly impaired.

The present invention aims to provide a counting, alignment, and delivery device that solves all of these problems.

[Means to solve the problem]

In order to solve the above problem, the present invention provides a large number of guide plates at equal pitch intervals on an endless chain stretched around a sprocket, and forms cut and raised spring parts and guide parts on the guide plates. The present invention is characterized in that it is provided with a pusher that can move up and down to push out the conveyed object held between the guide plates in a downward direction.

[For production]

With this configuration, objects to be transported such as paper diapers are arranged in a line between a large number of guide plates provided at equal pitch intervals. The conveyed object is held by a cut-and-raise spring formed on the guide plate. When the number of transported objects aligned and held in this manner reaches a certain number, the pusher descends and pushes out the transported objects held by the cut-and-raise spring. The objects arranged in a fixed quantity and extruded are transported to the 5th step.

〔Example〕

An embodiment of the present invention will be described in detail below. In FIG. 1, an endless chain stretched around a sprocket 3 is provided with guide plates l at equal pitch intervals. As shown in FIG. 5, this guide plate 1 has a guide portion 1' and a cut-and-raised spring portion 2 formed therein. 4 is a support stand;
As shown in FIG. 3, the substrate 1? It is fixed to via a bracket 20. 5 is a pusher, which is a guide plate 1 that is attached to an endless chain and moves in the direction of arrow A.
(Fig. 83, Fig. 4).

8 is a rack integrally fixed to the pusher 5, and 9 is a pinion, and the pusher 5 moves up and down via the rack 8 and pinion 9.

That is, in FIGS. 2 and 4, the pinion 9 is connected to the support plate 1 which is bent into a U-shape so as to sandwich the support base 4.
It is pivoted at 0. Also, one side of the rack 8 has a slider 2 that moves up and down within a guide 18 fixed to a support plate lo.
3, and the rod of the cylinder 18 is connected to this slider 23. Thereby, by operating the cylinder 19 to move the slider 23 up and down, the rack 8 moves up and down, and the pusher 5 moves up and down. In this operation, the racks 8 on both sides are synchronously moved up and down via the pinion 9, and thereby the pushers 5 on both sides are moved up and down synchronously. Guide rods 6 are integrally fixed to the pusher 5, and are provided at four locations passing through the support plate 10, as shown in FIG. 7 is a guide member fixed to the support plate 10.

The support plate IO is, as shown in FIGS. 3 and 4,
It is movable in the transport direction along guide rails 11 formed on the support base 4.

Reference numeral 12 denotes a drive motor for the support plate 10, which rotates the screw forest 13 pivotally supported by the support base 4. This results in
Propulsive force acts on the threaded portion 14 fixed to the support plate 10, and the support plate 10 moves.

Further, during this movement of the support plate IO, the support plate IO is stabilized by the shaft support of the pinion 9 bent in a U-shape so as to sandwich the support base 4. Reference numeral 15 denotes a long hole for allowing the shaft 24 of the pinion 9 to move.

21 is an auxiliary plate, and 22 is a supply conveyor.

Note that in FIGS. 1 to 4, the same parts are indicated by the same reference numerals, so a description of one overlapping part will be omitted.

The operation of this embodiment configured as above will be explained next.

The conveyed object 16 carried in by the supply conveyor 22 is sandwiched between the guide plates 1 and is assisted by the auxiliary plate 21 and transferred. From the point where the guide plates 1 are removed from the auxiliary plate 21, the guide plates 1 become parallel to each other, strongly sandwiching the conveyed object 16, and the conveyed object is held by the cut and raised spring portions 2. In particular, disposable diapers, which are light and soft and have uneven folded thickness and vertical and horizontal dimensions, are aligned by being sandwiched between guide board workers.

Next, a counter (not shown) counts the number, and when a predetermined number is reached, the cylinder 18 is actuated to lower the pusher 5 and push out the conveyed object 18. For example, in the example shown in FIG. 1, the number of objects 1B to be transported is eleven. 5' indicates the lowered position of the pusher 5, and by pushing out the pusher 5, the vertical entry and exit of the conveyed object 1G is adjusted.

That is, the conveyed object 16 held by the cut and raised spring section 2
When the object 1θ is pushed by the pusher 5, the conveyed object 1θ is adjusted in the vertical direction and is further pushed out by the pusher 5.
Vertical entry and exit is arranged between the door and the floor.

In addition, the pusher 5 moves in the vertical direction and also moves in the conveyance direction with the support plate 1 (l) moved by the drive motor 12, and the combination of these two movements causes the pusher 5 and the conveyance being conveyed to The object 16 is pushed out while remaining stationary with respect to the transport direction.The combination of the above operations allows continuous transport.

When the pusher 5 rises, the pusher 5 returns to its original position without contacting the subsequent conveyed object I6.

Further, the pushers 5 are provided on both sides of the guide part 1, and the up and down movements are performed synchronously by the rack 8 and the pinion 9, so that both ends of the conveyed object 16 protruding from both sides of the guide plate 1 are pushed at the same time. and its alignment is not disturbed.

〔Effect of the invention〕

As detailed above, according to the counting, alignment and delivery device according to the present invention, a guide plate having a cut-and-raised spring portion and a guide portion is attached to an endless chain at equal pitch intervals, and is held by the cut-and-raised spring portion. Since the conveyed object is pushed out by a pusher that can move up and down, even if the conveyed object is uneven in size and lightweight and soft, such as a disposable diaper, it can be held between the guide plates and the thickness can be adjusted. It is also possible to arrange the vertical entry and exit of conveyed objects.

Then, when the counter counts the number and reaches a predetermined number, the pusher is lowered to push out the conveyed object, making it possible to count the conveyed objects.In addition to the above effect, even conveyed objects such as disposable diapers can be counted. Arrangement and delivery can be performed reliably.

As a result, complete automation of packaging equipment, etc. can be achieved, productivity can be improved, and in addition to greatly reducing labor costs, the appearance of packaged products will be better, increasing product value, etc. Has excellent effects.
