Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a palletizer for bookbinding in which band-wrapped books, cartons, etc. are automatically stacked in sequence on a pallet.

[0002]

2. Description of the Related Art A conventional palletizer for bookbinding or the like picks up one-by-one articles such as band-wrapped booklets supplied by a conveyor with a robot hand and arranges them on a pallet or an article row previously stacked. After arranging the minutes' items, they were pushed from all sides by the packers to close the gap and align the front, back, left and right.

[0003]

An apparatus for picking up and stacking books and the like with a robot hand requires an operation space for the robot hand above the uppermost stage. Since the height of this operation space is relatively large, there is a problem that when the ceiling is low, the height of books bound on a pallet becomes low.

The present invention has been made to solve this problem, and an object thereof is to provide a palletizer such as a bookbinding machine having a relatively small space for stacking required above the uppermost stage. To provide.

[0005]

[Means for Solving the Problems] To achieve the above object, the means adopted by the present invention is to store a pallet supported by an arm of a lifter in a frame of a palletizer such as bookbinding, and bind to the front outer surface of the frame. A pitch feed conveyor for arranging items such as items can be lifted up and down, a roller shutter with a row of rollers of about the same size as the pallet is installed in the upper part of the frame, and front and rear and left and right pushing sliders are provided on the roller shutter. , The front and rear push-in sliders sequentially traverse the articles such as bookbinding arranged on the pitch feed conveyor and transfer them to the roller row of the roller shutter, and the left-right push-in slider grips the bookbinding article for one step on the roller row. Then, the roller row is circulated upward, and the pallet is raised to make one-stage bookbinding or the like. The lies in the so accumulate on the article stage laden the pallet or previously.

It is desirable that a sensor for detecting an article such as a book to be supplied to the pitch feed conveyor and a driving means for moving the conveyor according to the signal of the sensor are provided so that the interval between the articles on the conveyor can be adjusted.

[0007]

First, the roller row of the roller shutter is turned to the first position, and the lifter raises the pallet to support the roller row. Next, the articles such as bookbinding on the pitch feed conveyor are arranged at a predetermined interval, then the pitch feed conveyor is raised to the first position of the roller shutter, and the articles such as bookbinding placed on the pitch feed conveyor are pushed back and forth. The slider moves it onto the roller row at the first position of the roller shutter. By repeating this operation a predetermined number of times, an article such as a bookbinding for one step is arranged on the roller row. Then, the left-right pushing slider is moved from the left-right direction to the center to grip the article such as bookbinding for one step from the left-right direction.
Next, the roller row of the roller shutter is circulated from the first position to the second upper position, and then the pallet is lifted to load one-stage articles such as bookbinding on the pallet. Therefore,
When the left / right push-in slider is opened, articles such as a bookbinding for one step are stacked as they are on the pallet. By repeating the above operation, articles such as bookbinding are stacked on the pallet. The stacking height is the first in the row of roller shutters.
Although it is up to the position, the height from the first position to the ceiling is equal to the sum of the vertical width of the roller shutter and the vertical width of the push-in slider, but this vertical width is the vertical width required by the conventional robot hand. By comparison, since the size is significantly small, it is possible to stack articles such as band binding up to the height of the ceiling.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A palletizer of the present invention will be described based on the embodiments shown in the drawings. As shown in FIG. 1, the palletizer has a frame 10 composed of four columns 11 and beams 12 connecting the upper ends of the columns.

The arm 14 supports a pallet 15 and stacks the bound book 16 on the pallet.

A pitch feed conveyor 17 is provided on the outer front surface of the frame 10 through a cylinder so as to be movable up and down as shown by an arrow B. The pitch feed conveyor 17 runs in the left-right direction indicated by arrow C. The pitch feed conveyor 17 has a sensor for detecting the supplied bookbinding 16 and a driving means for controlling the traveling of the conveyor according to the signal of the sensor, and it is possible to adjust the bookbinding interval on the conveyor. .

A roller shutter is provided inside the frame 10
Build 18 The roller row 19 of the roller shutter 18 circulates between a horizontal first position and a horizontal second position above it as indicated by an arrow D. The first position corresponds to the uppermost stage of bookbinding that can be stacked on the pallet 15, and the second position is higher than that by one stage or more of bookbinding. The size of the roller row 19 is substantially equal to the size of the pallet 15.

Front and rear push-in sliders 20 are attached to the front and rear beams 12 of the frame 10. Front-back push slider 20
As shown by arrows E and F, has a movable plate 21 that is reversible and can move forward and backward, and a fixed plate 22 that receives bookbinding in the rear. Left and right push-in sliders 23 are attached to the left and right beams 12 of the frame 10, and the left and right packers 24 are opened and closed as indicated by an arrow G.

A roll sheet 27 is provided on the pillar 11 on the rear side of the frame 10.
The paper feed roll 25 near the second position of the roller row.
Attach. Slide cutter in front of the paper feed roll 25
When 26 is attached and the interleaving paper of a certain length is delivered from the paper feeding roll 25, the slide cutter 26 advances as shown by an arrow H to cut the interleaving paper. A stock conveyor 30 for stocking book stacks is provided so as to be connectable to the pitch feed conveyor 17. A turn conveyor (31) that changes the direction of bookbinding is provided in front of the stock conveyor (30).

Next, the operation of the present invention will be described. In advance, the roller row of the roller shutter is circulated to the first position, and the roller row is supported by a pallet from below. As shown in FIG. 2, one step on the stock conveyor 30
Arrange the bookbindings for each row in the specified direction,
Each bookbinding is transferred to the pitch feed conveyor 17 as indicated by arrow I. At this time, the traveling of the pitch feed conveyor 17 is automatically controlled so that the bookbindings transferred thereon are lined up at a predetermined interval. When one row of bookbindings 16 is transferred onto the pitch feed conveyor 17, the pitch feed conveyor 17 is raised as indicated by arrow J to reach the same level as the roller row in the first position of the roller shutter.

As shown by an arrow K in FIG. 3, the movable plate 21 of the forward / backward pushing slider 20 pushes the bookbinding 16 on the pitch feed conveyor 17 onto the roller row 19, and then pushes the bookbinding against the fixed plate 22. A roll bridge 28 is provided between the first position of the roller row of the roller shutter 18 and the pitch feed conveyor 17. When the operations shown in FIGS. 1 and 2 are carried out the number of times equal to the number of columns in one stage, as shown in FIG.
The bookbinding 16 for one stage is arranged on the roller row 19. At this time, the space in the front-rear direction of the bookbinding 16 for one step is closed, but the space in the left-right direction remains open.

Then, as shown in FIG. 5, the packer 24 of the left-right pushing slider is moved toward the center by a predetermined distance as indicated by an arrow L to close the left-right space between the bookbindings 16, and
Hold the entire book. In this state, as shown by the arrow M in FIG. 6, the roller row 19 is circulated from the first position to the upper second position. Since binding on the roller row is held by the left and right pushing sliders, the roller row 19 of the roller shutter 18 can smoothly circulate. Then, arrow N
As shown in, the pallet 15 is raised slightly to receive the bookbinding 16.

Then, when the packer of the left-right pushing slider is opened, the bookbinding for one step is loaded on the pallet. Therefore, rotate the paper feed roll 25 by a predetermined number of revolutions
29, and then the slide cutter 26 is operated to cut the interleaving paper 29, and the interleaving paper 29 is placed on the entire one-step bound book.
Lay. The bookbinding for one stage is stacked by the operation from FIG. 2 to FIG. By repeating this, as shown in FIG. 7, the bookbinding can be stacked on the pallet 15 until the uppermost step reaches the first position. All the steps from FIG. 2 to FIG. 7 can be automated. As shown in Fig. 1, the upper and lower widths of the space above the uppermost bookbinding are roller shutters.
18 is the sum of the vertical widths of the front / rear and left / right push-in sliders 20 and 23, and the vertical widths of these are relatively small.
Can be stacked. Although the embodiment shows stacking of bookbinding wound in a band, it goes without saying that cartons and the like can be stacked as well.

[0017]

As described above, in the palletizer of the present invention, the articles such as bookbinding on the conveyor are pushed horizontally by the pushing slider and fed to the roller row of the roller shutter, and the one-step bookbinding etc. fed to the roller row. This is a method of stacking articles such as bookbinding for one step on the pallet or the article stacked in front of it by holding the article of another item with another push-in slider and circulating the roller row upward. Since the vertical width of the space required above is much smaller than the conventional robot hand method that picks up and stacks conventional articles, even in a space with a low ceiling, articles such as books can be stacked high enough on a pallet. It has an excellent effect that it can.
