Abstract

PURPOSE:To surely separate sheet-like materials and to accumulate the same in order, by providing a separating arm in the boundary section between variable and stoppable first and second conveyers, at a level equal to both conveyers, which separating arm is adapted to be rotated and elevated by a predetermined angle. CONSTITUTION:A separating arm 15 is disposed in the boundary section between first and second conveyers 13, 14 which may separately changes speed and stop. During normal operation, the separating arm 15 is located at its lower position while the first and second conveyers 13, 14 are driven at an equal speed so that sheet-like materials P are conveyed through a gap in the separating arm 15 in the direction of the arrow. When the number of the sheet- like materials reaches a predetermined value, the separating arm 15 is rotated and elevated, and the first conveyer 13 is stopped simultaneously with the separation of the sheet-like materials P while the second conveyer 14 is driven at a high speed to convey the sheet-like materials P to an accumulating section 20. Then, the separating arm 15 is lowered while the second conveyer 14 is stopped. When the transfer of the sheet-like materials P in the accumulating section 20 into the next process station is completed, the conveyers 13, 14 are returned into their normal operating modes. Thereby, it is possible to surely accumulate the sheet-like materials.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is based on punching into a predetermined shape and removing unnecessary parts. This invention relates to a sheet-like material separation and transfer device that feeds a predetermined amount of sheet-like material at a time when transporting the removed sheet-like material, such as a carton blank.

[Prior art and drawbacks]

Currently, in order to stack carton blanks in predetermined amounts after punching them into predetermined shapes and removing unnecessary parts, it is necessary to reliably separate them into predetermined amounts and transport them to the stacking section before stacking them. For this separation and transfer, two belt conveyors t++ (2) are used as shown in Fig. 5, and conveyor 11).
At the end of A1,1, the presser roller (3) moves up and down, and at separation 11,'r, the conveyor (1) stops and the presser roller I;]) lowers the carton blank. suppress. -10,000 conveyor)'' (2) is a mechanism that rotates at high speed L and transfers carton blanks to a predetermined floor.However, in the case of carton blanks, the punched shape is complicated, - The front and back parts of the carton blanks that meet each other get caught, and when they are lined up at the separating part, they are not separated but are diagonally, so that they can be stacked smoothly at the stacking part. In case I, the carton blanks could not be separated and the machine had to be temporarily stopped.

[Problems to be Solved] Carton blanks punched into a predetermined shape and unnecessary portions removed are provided in a predetermined amount at a time reliably and in an aligned state to a separating and transferring device capable of separating at 0T.

"" Dinghai 51 Tei City Town 1 Tunna 1. It consists of the first and second conveyors, and at the boundary between the first and second conveyors there is an I-arm that is usually at the same height as both conveyors and that rotates and rises at a certain angle when separated. The problem was solved by setting it up.

[In use 1 During normal operation, the molecule ill? , in Endurance Ending Samurai,
After the first competition, the speed of the second conveyor can be changed, and the carton blanks can be separated by lifting and separating the partially overlapping carton blanks, rather than simply pressing them down. 16 feeds can be carried out smoothly without getting caught.

〔Example] B. Embodiments of the invention will be described with reference to the drawings.

Are the carton blanks arranged in a predetermined number of rows on a pallet, with a predetermined number of rows and a predetermined number of stages? Discharging section 11. ]0), in which the separation and transfer device of the present invention is used in the conveyance section 10).

As shown in Fig. 2, this vinegar feeding section 10) is a telescopic conveyor (]1) that expands and contracts according to the position of the delivery part of the punching machine.
, This telescopic conveyor 11) can be shifted at the same speed in the upward traveling direction as indicated by the Y conveyor U, 2). It consists of a first conveyor 1I31 and a second conveyor U4+ that can change speed and stop OT with five types of caterpillars.

At the boundary between the first conveyor r (131 and the second conveyor 14), there is an equinox arm f15 which is at the same height as both conveyors during normal operation and which rotates and rises by a certain angle during separation.
1'lX: Separation and transfer device provided.

As shown in Fig. 6, this separation arm 115) consists of a U-shaped arm (ISb) that extends diagonally from the spindle (15a) attached to the machine body to the conveyor, and a carton blanking presser rod end. It consists of a presser arm (15d) provided with a rotating roll (15c,).

Next, the separation single general feeding device of the present invention will be explained.

First of all, during normal operation, as shown in Figure 1A), minute A (to arm 1.151 'i is located above and below, the first conveyor (13) and the second conveyor 114) are at the same speed at low speed. As shown in the same figure (b), the separation arm t1.
51 rises one rotation, and at the same time the carton blanks are separated, the first conveyor (13) stops, the second conveyor (old) is shifted to high speed operation, and the carton blank on the second conveyor (I) is moved to the first east. Next, when a predetermined number of carton blanks are piled up in the primary drain section 12o, the separating arm is moved as shown in Fig. 4(c).
I4! At the same time, the second conveyor (14) is also stopped and the stacked carton blanks are sent to the next process. This is the end of the first conveyor 11 as shown in the same figure (-J).
31 and the second conveyor (14) rotate at low speed (~, carton blanking becomes durable under normal conditions).

The above-mentioned separating and assembling mechanism works more effectively if it is not in the water/F-state (the first conveyor and the second conveyor are arranged so as to rise in an oblique direction).

The above explanation was about the carton blank, but
It can be used not only for carton blanks, but also for sheet-like materials such as paper and plastic sheets, which are placed on a conveyor in a partially overlapping pM and are generally conveyed.

〔effect〕

Since the separation and transfer device t of the present invention has the above configuration,
When the sheets are partially stretched together like nails, the sheet should be stretched at the specified position 1 for 141# without the sheet bottom □ proboscis being caught or the lower sheet being slanted □. Therefore, a predetermined number of sheet-like materials could be neatly stacked in the stacking section.

In addition, it is possible to reliably separate even sheet-like materials such as carton blanks, which have complicated punched shapes and tend to catch on each other.
