Abstract

PURPOSE:To align stacked articles in one layer efficiently by disposing a carry- out conveyer in front of a carry-in path for carrying in boxed articles stacked in two layers and arranging transport conveyers for clamping and transporting the boxed articles to the carry-out conveyer above both sides of the carry-in path. CONSTITUTION:With boxed articles A1, A2, A3, A5 previously entered on a carry-in path 1, when boxed articles A4, A7 are pushed out onto the carry-in path 1 by a carry-out pusher 12, the boxed article A1 is pushed out onto a carry-out conveyer 2 and first transported. Subsequently, the upper boxed article A2 is disposed above both sides of the carry-in path 1, clamped by a pair of transport conveyers 3, 3 moved at a speed higher than the carry-in speed to be transported onto the carry-out conveyer 2, and then carried out after the boxed article A1. Thus, the boxed articles A3, A4, A5, A7 are on standby on the carry- in path 1. By repetition of such operation, these boxed articles are sequentially aligned in one layer and transported.

Description

[Detailed description of the invention] The present invention relates to a transport device for box products.

The so-called cellophane wrapper used in the final packaging process for cigarettes, etc. is equipped with a stacking mechanism for boxed products, in which the boxed products wrapped in a predetermined number of cigarettes are wrapped in cellophane, and the boxed products are stacked. Stack and discharge.

However, the carton packaging machine for packaging the above-mentioned boxed products one carton at a time is also provided with a stacking mechanism, and only one tier of boxed products can be carried into the packaging machine.

It was mechanically difficult to release the stacking mechanism of either the cellophane wrapper or the carton packaging machine.

Even if the stacking mechanism of the carton packaging machine is released,
Since the cellophane wrapper and the carton packaging machine are connected by a flat-held conveyor or the like, if they were left stacked in two tiers, the cargo would collapse, so it was necessary to make it into one tier for transportation.

The present invention has been made in view of the above-mentioned conventional circumstances, and an object of the present invention is to provide a transport device for box products that aligns stacked box products in one layer, and to provide a transport device for box products that arranges stacked box products in one layer, and to transfer the cellophane wrapper and carton packaging machine. The purpose is to perform efficient carton packaging by making connections possible.

Such a conveying device for boxed products of the present invention is provided with a carry-in path for carrying in boxed products stacked in two stages, upper and lower, and has an unloading conveyor in front of the carry-in path, and also clamps the boxed products on both sides of the upper stage of the carry-in path to control the carrying-in speed. The present invention is characterized in that a transport conveyor is provided for transporting the box products to the discharge conveyor at a faster speed.

An example of carrying out the present invention will be explained with reference to the drawings. Figure 1 shows a transport system for boxed products connected to a cellophane wrapper (11).
The installation state of (10) is shown, and the cellophane wrapper (11) is shown.
The paper box products (A) carried in from the carry-in section (20) are covered with cellophane wrap, stacked in two tiers in the stacking section (21), and pushed out by the carry-out pusher (12).

The transport device (10) for boxed products will be explained with reference to FIGS. 2 to 4. In the figure, (1) is the carry-in path for carrying in the boxed products (A) pushed out by the carry-out pusher (12); A carry-out conveyor (2) formed by a belt conveyor is disposed in the front, and conveyors (3) are disposed on both sides of the carry-in path (1).

The conveyor (3) is a belt conveyor consisting of four belt wheels (4) and a belt (5), and carries boxed products (A
) are higher than the carry-in path by the height of the box products (A), and are arranged facing each other with an interval equal to the width of the box product (A). In addition, the conveyor (
The terminal end of 3) projects onto the discharge conveyor (21).

Driven belt pulleys (6) are provided coaxially with the belt pulleys (4) on the carry-in side of the transport conveyor (3), and the driven belt pulleys (6) are connected to the driving machine ( 9
) to drive the conveyor (3).

A cover plate (13) is provided above the transport conveyor (3) so as to be openable and closable to prevent the boxed products (A) from flying out, thereby preventing the boxed products held by the transporting conveyor (3) from flying out.

If you try to pass the second step further, the lid plate will lift up and the limit switch (14) will activate, alerting you to the presence of a foreign item.

The operation of the above embodiment will be explained with reference to FIGS. 5 to 7. First, the box product (Al
) (Al), boxed products (Ax) (A2) (A3) (A5) that have been brought in in advance are waiting on the loading path (1) (Fig. 5).

When the box products (A4) (Al) are pushed up the carry-in path (1) by the carry-out pusher (12), the box products (Ax) are pushed onto the carry-out conveyor (2) and transported first (
Figure 6).

The stacked boxed products (A2) are pinched by the conveyor (3) and conveyed onto the unloading conveyor (2), and then the boxed products (A2) are
x) will be carried out next, and boxed products (A3) (A4) (As) (Ay) will be carried out next to the carry-in path (1).
(Fig. 7), and the above steps are repeated.

The box product conditioning device of the present invention can be used not only for cigarettes but also for all packaging machines that package similar products. or,
In the above example, the boxed products were brought in intermittently, but
It can also be applied to continuous loading.

As described above, the present invention provides a carry-in path for carrying in boxed products stacked in two levels, one above the other, a carry-out conveyor in front of the carry-in path, and a speed faster than the carry-in speed by sandwiching the boxed products on both sides of the upper stage of the carrying-in path. Since the box product transport device is configured to include transport conveyors for transporting the box products to the discharge conveyor at a high speed, the stacked box products can be arranged in one layer. Therefore, the connection between the cellophane wrapper and the carton packaging machine can be made without any mechanical improvement, and extremely economical carton packaging can be achieved, and since the packaging is in one stage, the load will not collapse during transportation.

Thus, the desired goal is achieved.
