Abstract

PURPOSE:To enable stacking and arrangement with a unidirectional pusher by providing a cut-out pusher to be engaged with a plurality of box-like objects corresponding to the number of stacks on a front end of a box-like object array so that the pusher can be freely swung toward a downstream direction along a path. CONSTITUTION:In a stacking mechanism 5, a path 5a with a side in a 1/4-arc continuously extending downward or upward from a downstream extension position of a carry mechanism 4 is segmented into rectangular shapes in a cross section, and a cut-out pusher 5b which appears in the path 5a to be engaged with a plurality of box-like objects A corresponding to the number of stacks on a front end of a box-like object array A1 is provided freely swingable in a downstream direction. Therefore by a rotation of a box-standing turret 3, the box-like objects A are sequentially stood straight. Then these straight standing box-like objects A are pushed by the carry mechanism 4 to an entrance of the 1/4-arc path 5a of the stacking mechanism, and with a swinging of the cut-out pusher 5b the box-like objects A by the number corresponding to the number of stacks from the head of the stacked object array A1 are pushed along the path as they are in contact with one another. Thus stacking and arrangement can be done with a unidirectional pusher.

Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Application Fields The present invention relates to a stacking alignment and feeding device which collects box-shaped articles such as small packets of cigarettes into predetermined numbers and supplies them to a stacking and packaging device for the next process; Specifically, on the downstream side of a 1f1m structure in which box-shaped articles brought in horizontally in a flat state are stacked in a predetermined number of tiers, there is an alignment mechanism that aligns the stacked box-shaped articles by touching each other while horizontally transporting them. , and a separation/unloading mechanism that separates and transports the aligned box-shaped articles into predetermined numbers.

Conventional technology> Conventionally, as this type of stacked alignment and supply device, for example, the Japanese Patent Publication No. 1
-As disclosed in Publication No. 14092, first, box-shaped articles that are laid flat and transported horizontally are stacked one by one, and then two boxes are stacked from the top.
A pusher that reciprocates horizontally sends out the goods laterally to each item, converts them into two-tier stacks, and transports them horizontally on a belt conveyor.A pusher that reciprocates horizontally in a direction perpendicular to the belt conveyor then sequentially stacks the two-tiered boxes of goods. By feeding the stacked articles laterally so that they come into contact with each other and aligning them on the conveyance path, and when the head of this row of stacked articles reaches the elevator connected to the front end of the conveyance path, the elevator is raised by a sensor. Separate and lift a predetermined number of box-folded articles from the front end of the stacked article row from the stacked article row on the following conveyance path, and then push out the box-folded articles on the elevator by a discharge busher and supply them to the stacking packaging device. There is something.

Problems to be Solved by the Invention> However, in such a conventional stacked alignment and supply device,
Since the stacking and aligning work of box-shaped articles is performed by the reciprocating bushers, the stacking and aligning work is interrupted when the reciprocating bushers retreat without pushing the box-shaped articles, and the operation cycle time per cycle is shortened accordingly. As a result, there is a problem in that it is not possible to increase the speed of the apparatus, that is, to increase the amount of boxed articles supplied to the integrated packaging tower per unit time.

In addition, the transport direction of the box-shaped articles changes three times perpendicularly from the start position of the stacking operation to the end position of the alignment operation, and the amount of movement is required to be long, resulting in a line of 11 lines. There is also the problem that it is difficult to increase the speed.

), only the lower surface of the conveyance path (6b) is extended by the front and rear width dimension of the box-shaped article group (A2>), and the discharge busher (7C) is conveyed to the side of the extended surface (6b+). It is arranged perpendicular to the direction.

Therefore, the speed can be increased to the extent that the group of box-shaped articles (A2) is not raised by the elevator (7b) as in both of the above embodiments.

Next, the operation of such a stacked arrangement and supply device will be explained.

First, in the initial state, the stopper (2) disposed between the carry-in conveyor (1) and the box lifter turret (3>) moves upward, and the box-shaped articles (A) are randomly supplied from the cartoning machine. ...
Slip onto the carry-in conveyor (1) and store it,
The stopper (2〉) moves downward in synchronization with the timing when the box raising turret (3) passes through the recess (3b+), and the line pressure moves one box-shaped article (A) located at the front end into the recess (3b). Push it into.

Thereafter, the box-shaped article (A) engaged in the recess (3b+)
is reversed 90 degrees by the rotation of the circular wheel (3a) and placed on the cradle (
3C> and are pushed out one after another onto the three-sided conveyor (4a) of the transport am (4), and from then on both holding plates (4b) (4b) are pushed out onto the three-sided conveyor (4a) of the conveyor am (4).
It is transported horizontally between

These both holding plates (4b) (4b) are connected to the sensor (4d
> opens only when the boxed articles (A)... are stored in contact with each other to a predetermined position on the three-sided conveyor (4a), and the opening roller (4az) (4az) is opened intermittently. Due to the closing movement, the row of box-shaped articles (A1) in units of 10 pieces is moved to stage M.
Every time the cutting pusher (5b) of the mechanism (5) passes, two pieces from the beginning are pushed into the entrance (5a+) of the 1/4 arc-shaped passage (5a).

At the same time, each strip (5b+) of the cutout pusher (5b) is pushed into the entrance (5a+) of the passageway (5a) by the rotation of the rotary body (5bz).
A), the two are pushed along the passageway (5a) while being turned 90 degrees while in contact with each other, and the exit (5a3
), 21[1i1 box-shaped articles <A) (A
) are laid flat again and stacked in two layers.

Thereafter, the two-tiered box-shaped articles (A) (A) are horizontally transferred by the alignment mechanism (6), and the following two-tiered box-shaped articles (A) (A) are brought into contact with each other. At the same time, the aligned box-shaped articles (A
)... are separated into a predetermined number of box-shaped article groups (A3) and transported to an accumulation packaging device.

From then on, the above-described operations are repeated continuously.

In each of the above embodiments, the box-shaped articles (A) are arranged in two rows and five rows of 10
Although the case of combining into units is shown, the case is not limited to this, and the same effect can be obtained even if the number of stacks and the number of arrays are converted, and the example shown in FIG. The cut-out bushing (5b) shown, the discharge bushing (7C) shown in FIGS. 6 and 7, etc. may be partially replaced.

Furthermore, the conveyance mechanism (4) is not limited to the structure described above, and for example, as shown in FIGS. ) placed horizontally and pushed out onto the pedestal (3C) (A>

), and this passage (5a + entrance (5a +
For example, an elastic support (4e) such as a brush is placed horizontally on the downstream extension line of the support surface (4C) and above it in parallel so as not to come into contact with each strip material (5b+) of the cutout button (5b). This prevents each box-shaped article (A>) pushed into the entrance (5a+) from moving up and down before it engages with each strip (5b+).

In the illustrated example, the conveyance section (4a') is used for each box-shaped article (A).
) is a pair of belt conveyors that are sandwiched between the left and right sides of the box, but in place of these, a busher that moves back and forth horizontally from inside the box lifter turret (3) toward the entrance (5a+) is installed. Or each recess (3b+) of the box raising turret (3)
) may be directly pushed into the inlet (5a+) using a rotary pusher (3bz) connected to the inlet (5a+).

<Effect of the invention> Since the present invention has the above configuration, it has the following advantages.

■The front end of the box-shaped articles carried in flatly engages with the recess of the box-raising turret, and the rotation of the box-raising turret causes the box-shaped articles to stand upright one after another. The articles are pushed out to the entrance of the 1/4 arc-shaped passage of the stacking mechanism, and the rotation of the cut-out pusher causes box-shaped articles whose number is equivalent to the number of stacks to come into contact with each other from the forward side of the row of stacked articles. By being pushed along the path in this state, the box-shaped articles are again laid flat and stacked, and then the stacked box-shaped articles are aligned by the alignment mechanism, so that the one-way busher allows the stacking and stacking. Can perform alignment work.

Therefore, compared to the conventional system in which the reciprocating pusher performs the stacking and alignment work in one step, the pusher does not need to retreat when it does not push out the boxed goods, so the time for one operation cycle is shortened accordingly. The time required for one alignment operation can be shortened, and as a result, the speed of the device can be increased and the number of feeds per unit time can be increased.

■Compared to the conventional system, in which the direction of transport of box-shaped articles changes three times perpendicularly from the start position of stacking work to the end position of alignment work, and the moving distance is long, the direction of transport of box-like goods is approximately By standing the box-shaped article upright in one direction, the moving distance is shortened, which simplifies the line and increases the speed of the device.
