Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a paper turning device for wrapping paper, etc., which is capable of automatically opening, transporting and removing wrapping paper for wrapping paper, or automatically sending out stacked paper bundles one by one from the uppermost paper.

[Conventional technology]

For example, in printing factories, bookbinding factories, etc., paper packages transported by a forklift or the like are placed on a stationary elevator and raised to a predetermined height by the elevator. The wrapping paper of the packaging is manually removed and the paper packaging is transferred to the next process, but such manual work requires a lot of time and effort, resulting in extremely low work efficiency. There was a problem with it being bad. This invention was made to solve the above problems, and it is possible to automatically and smoothly open and remove the wrapping paper of a paper package placed on an elevator, and to automatically and sequentially address stacked paper stacks one by one. It is an object of the present invention to provide a paper turning device for wrapping paper, etc., which can be rolled up and sent out of the system, thereby improving efficiency and saving labor in this type of work.

[Means to solve the problem]

The device for turning paper such as wrapping paper according to this invention includes a running body that is driven to run in the front and rear directions on the upper part of one side wall, and an outer guide member of an elevator that is driven up and down with a stack of paper placed thereon. A plate-shaped cam is provided which gradually slopes higher toward the paper turning direction of the body, and the proximal end side is rotatably supported by the running body, and the wrapping paper of the paper packaging body or the uppermost paper surface of the stacked paper bundle is provided. A guide roller is rotatably supported on the base end side of a paper turning crank arm that is pressed against the paper, and the guide roller is supported in a rolling or sliding manner on the plate-shaped cam.

[Effect]

In this invention, when the traveling body is driven to run in the paper-turning direction, the guide roller rolls on the plate-shaped cam toward the high slope side, causing the crank arm to rotate upward in the reverse direction. The wrapping paper of the paper package on the elevator is turned open by the crank arm, and in the case of stacked paper bundles, the uppermost paper is turned over and sent out of the system. Thereafter, the traveling body is driven in the opposite direction to return to the paper stack turning standby position. By repeating the above operations, the wrapping paper is removed from the paper package or the stacked paper bundle is turned over and conveyed one by one.

【Example】

An embodiment of this invention will be described below based on the drawings. In FIG. 1, reference numeral 1 denotes an outer guide member for an elevator consisting of a box whose front and upper surfaces are open, and within this outer guide member 1 a lifting table 2 for the elevator is arranged. This elevating table 2 has a paper package or stacked paper stack P placed on the upper part thereof, and is driven up and down by a drive means (not shown). A running body 4 that is driven to run in the front-rear direction along a guide rail 3 (see FIGS. 2 and 3) is provided at the upper part of one side wall of the surrounding guide member 1. In this embodiment, the drive means 5 for the traveling body 4
consists of a motor 6, a main sprocket 7 fitted to the output shaft of the motor 6, a slave sprocket 8 (see Fig. 2) pivotally supported at a position separated from the rear of the main sprocket, and the traveling body 4. It consists of an endless chain 9 whose front and rear ends are connected to each other and which are wound and meshed with the sprockets 7 and 8. The traveling body 4 includes an outer guide member 1.
The base end side of a crank arm 10 for paper turning that extends upwardly inside the paper package is rotatably supported, and the wrapping paper H of the paper package P is attached to the crank arm 10.
Alternatively, a plurality of friction imparting members 11 made of rubber rings or the like for imparting a friction force to the upper paper of the stacked paper bundle P are integrally arranged at regular intervals. Further, a guide roller 12 is rotatably supported on the base end side of the crank arm 10 at an eccentric position with respect to the shaft support with respect to the traveling body 4. The guide roller 12 is provided on the upper part of one side wall of the outer guide member 1 and is rotatably supported on a plate-shaped cam 13 along the guide rail 3. The illustrated plate-shaped cam 13 includes a horizontal cam surface 13a on the paper-turning start end side, and an inclined cam surface 13 that gradually slopes higher toward the rear from the rear end of the horizontal cam surface 13a.
The guide roller 12 is rotatably supported on these cam surfaces 13a and 13b. Further, at the upper part of the rear wall of the envelope guide member 1, a carry-out roller 14 for feeding out the wrapping paper H or the last paper of the paper bundle P on the lifting table 2 is rotatably supported. The illustrated example of the carry-out roller 14 is made up of a plurality of gears fitted at regular intervals to the output shaft of a motor 15 that drives the carry-out roller 14 in the paper feeding direction. In the above, the operation panel 1 is attached to the outer guide member 1.
6 is provided, and the operation panel 16 sequentially controls each of the motor 6 of the lifting table 2, the motor 6 of the traveling body 4, and the motor 15 of the carry-out roller 14. For this sequence control, limit switches L1 and L2 for controlling the speed of the traveling body 4 and limit switches for stopping the traveling body 4 are installed at the starting end and the terminal end of the guide rail 3, respectively, as shown in FIG. L3 and L4 are arranged respectively. In these limit switches, the speed control limit switches L1 and L2 set a low speed section between limit switches L1 and L3 and between L2 and L4, respectively, and set a high speed section between L1 and L2 as a high speed section of the traveling body 4. This is for speed control. In addition, the outer guide member 1 includes a lifting table 2.
Limit switches (not shown) are arranged to restrict the respective raised positions. Next, the operation of the above embodiment will be explained. First, a paper package or stacked paper bundle P that has been transported by a forklift or the like is placed on the lifting table 2 at the lowest position.
In the solid line state in FIG. 4 in which the crank arm 1 is mounted and the guide roller 12 is supported on the lowest horizontal cam surface 13a of the plate-shaped cam 13, the crank arm 1
The friction imparting member 11 of No. 0 presses the upper surface of the wrapping paper H of the paper package or the upper paper of the stacked paper bundle P on the paper turning start end side. In this state, when the motor 6 is started by a command signal from the operation panel 16, the traveling body 4 is driven to run in the paper turning direction, so that the guide roller 12 is inclined from the horizontal cam surface 13a of the plate-shaped cam 13. It rolls toward the cam surface 13b. At the beginning of this rolling, the guide roller 12 horizontally moves on the horizontal cam surface 13a of the plate-shaped cam 13, and at the time of this horizontal movement, the wrapping paper H or the stacked paper bundle P

sneaks in. Then, when the guide roller 12 rolls and transfers from the horizontal cam surface 13a to the inclined cam surface 13b of the plate-shaped cam 13, the guide roller 12 climbs the inclined cam surface 13b, so that the crank arm 10 moves as indicated by the chain line in FIG. As shown, it rotates in the upward reversal direction around the pivot support. As a result, the wrapping paper H is rolled up and spread out on the delivery roller 14. Thereafter, the paper packages P are sequentially removed from above, and when the load of the paper packages P on the unfolded wrapping paper H becomes lighter or completely eliminated, the wrapping paper H is moved forward by the carry-out roller 14. Transported and removed. On the other hand, in the case of stacked paper bundle P, the topmost paper is turned over in the reverse direction and sent forward. Thereafter, the traveling body 4 is moved backward by the reverse rotation start of the motor 6, and the guide roller 12 of the crank arm 10 is moved backward.
The crank arm 1 rotates downward from the inclined cam surface 13a toward the horizontal cam surface 13a.
0 rotates in the opposite direction, and the friction applying member 11 of the crank arm 10 returns to the position where it presses the upper paper starting end side of the paper stack P on the lifting table 2. Then, by sequentially repeating the above operations, the lifting table 2
The upper stacked paper stack P is automatically turned over and sent out one sheet at a time, starting from the uppermost sheet. In addition, during the above-mentioned paper turning operation, the elevating table 2 adjusts the amount by which the sheaf P decreases so that the upper paper of the sheaf P remaining on the elevating table 2 is held within a certain height range. are sequentially and intermittently driven upward.
