Abstract

PURPOSE:To improve work efficiency by erecting sheet-like bodies taken out by the first conveyer device one by one at the position of a presser member in a condition stacked in sequence by the second conveyer device then reversing them in sequence on the third conveyer. CONSTITUTION:When corrugated plates 1 are fed one by one from a paper feed section by the first conveyer device 3, they are in a condition stacked in sequence on the second conveyer device 4. If the first corrugated plate 1 is manually operated into a vertical state so as to be in contact with a presser member 16, tips of the corrugated plates 1 fed in a stacked condition are gradually guided upward. In this case, the lower end of the corrugated plate 1 in contact with the presser member 16 is shifted onto the third conveyer device 6 via the shift of the second conveyer device 4, and the corrugated plate 1 is pulled to the left at its lower end and reversed upside down and fed to a stacking section 7. When the corrugated plate 1 is erected by the presser member 16, it is in a stationary state, thereby the printed condition on the rear can be checked and work efficiency can be further improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a sheet reversing device for reversing a sheet material such as a corrugated board or paperboard from the front side to the back side or from the back side to the front side.

Conventional technology For example, when checking a corrugated board with printing on the back side turned over so that the printed side faces the front side, conventionally, a predetermined number of corrugated boards with the printed side facing down are stacked and then turned over 180 degrees. After that, the corrugated boards were sent out one by one and checked, and then a predetermined number of the checked corrugated boards were stacked.

Problems to be Solved by the Invention As described above, in the past, the work of inverting a predetermined number of stacked corrugated boards by 180 degrees and the work of sending out the reversed corrugated boards one by one for checking were separated. As a result, work efficiency was extremely poor.

The present invention solves these problems by, for example, feeding out corrugated boards one by one from a stack with the printing side facing down, and then standing up the corrugated boards on the moving path of the sent out corrugated board. The purpose of this invention is to improve work efficiency by checking the printing surface by turning the paper over after printing.

Means for Solving the Problem In order to solve this problem, the present invention provides a first conveyor device that sequentially takes out stacked sheets one by one starting from the lowest one, and a second conveyor device that receives sheet-like objects from a first conveyor device that is driven at a lower speed than the first conveyor device; a third conveyor device for receiving the body; and a third conveyor device for receiving the body;
The holding member is located above the front end of the conveyor device and is biased downward by a spring so as to come into contact with the upper end of the upright sheet-like member.

With this configuration, the sheet-like objects taken out by the first conveyor device are stacked one on top of the other on the second conveyor device, stand up at the position of the holding member, and then are reversed on the third conveyor device. do.

EXAMPLE Hereinafter, an example of the present invention will be described based on the drawings.

In the figure, 1... is a predetermined number of corrugated boards stacked in the paper feed section, and is printed on the neck. Reference numeral 2 denotes a front plate that comes into contact with the # end face of the stacked corrugated boards to restrict the shape.

3 is a first conveyor device arranged below the paper feeding section;
The front ends of the predetermined number of stacked corrugated boards 1 ride on this first conveyor M3 with their front ends facing downward, and are pulled out from the lowest corrugated board 1 in the direction of the arrow in FIG. ing.

The first conveyor device 3 rotates at a speed of 1, and the corrugated board 1 pulled out by the first conveyor device 3 is transferred to the second conveyor device 4 provided in front of the first conveyor group [3]. transfer to the top. The second conveyor device 4 is rotating at a speed v2 that is slower than the speed v1 of the first conveyor device 3, and therefore the corrugated boards 1 are sent in a sequentially overlapping state on the second conveyor device 4. Become. Reference numeral 5 denotes a presser device located near and above the front end of the second conveyor device 4, which presses the upper end of the corrugated board 1 standing on the front end of the second conveyor device 4 with enough force to prevent the corrugated board 1 from being deformed. This is to press it downward. Reference numeral 6 denotes a third conveyor device located so that the front end of the second conveyor device 4 fits into the front end, and this conveyor device connects the first conveyor device 3 and the second conveyor group W! It is rotating at a speed ■3 between the speeds of 14 and 14.

Specifically, it is set to be Vl:V2:Vl-3:1:2. 7 is the third conveyor group N6
This is a stacking section where the corrugated pole boards 1 sent out from the stacking section are stacked up. By the way, the presser device 5 is a second conveyor group! ! ! A circular support 8 located so as to straddle the vicinity of the front end of the support 8, screw shafts 9a and 9b provided vertically on both sides of this support 8, and a chain wheel provided at the upper end of the screw shafts 9a and 9b. 10a.

A chain 11 hung endlessly on the IQb, a handle 12 provided on one chain wheel 10a, and internally threaded portions 13a and 13b on both sides of the portal support 8 screwed into the threaded shafts 9a and 9b. The lifting member 13 moves up and down with the rotation of the shaft 9a, and the springs 15a and 15b, which are located below the lifting part 4113 and whose spring pressures are adjusted by spring pressure adjustment screws 14a and 14b, are provided so as to be biased downward. It consists of a holding member 16.

In the above configuration, when the first conveyor device 3 feeds the corrugated boards 1 one by one from the paper feed section, the corrugated boards 1 are stacked one on top of the other on the second conveyor device 4. Therefore, when the first corrugated board 1 is manually operated in a vertical position so as to be in contact with the presser member 16,
The corrugated board boards 1 that are sent in a stacked state are gradually guided upward with their leading ends. At this time, the lower end of the corrugated board 1 in contact with the presser member 16 is connected to the second conveyor ti'
Due to the movement of a4, the corrugated board 1 is transferred onto the third conveyor device 6, and at that moment the lower end of the corrugated board 1 is pulled to the left in FIG. . By the way, when the lower end of the corrugated board 1 is transferred from the second conveyor device 4 to the third conveyor device 6, the next corrugated board 1 is already in a substantially vertical state and its upper end is pressed by the presser member 16. By performing this operation in order, the corrugated board 1 is continuously automatically reversed one by one. During such an automatic reversing operation, for example, when the corrugated board 1 is pushed by the presser member 1G and stands up, it is almost in a stationary state. You can check the printing status of Note that the corrugated board 1 located on the left side of the corrugated board 1 in the vertical state in FIG. 1 is instantly transferred horizontally onto the third conveyor device i6, so that it does not interfere with checking the printed surface. Further, the apparatus of this embodiment may be installed in a process where it is necessary to perform some processing on the front and back sides of the corrugated board 1.

In the apparatus of the embodiment described above, the holding member 16 is used to hold the corrugated board between the state in which the corrugated board 1 is in the vertical position before it stands up, and the state in which the lower end of the corrugated board 1 is transferred onto the third conveyor device 16^. It is designed to be able to move up and down as the corrugated board 1 moves so that it comes into contact with the upper end of the corrugated board 1. Furthermore, since the corrugated board 1 is not limited to a certain size, the height of the presser member 16 must be determined according to the size of the corrugated board 1, and the height of the presser member 16 must be determined by operating the handle 12. This is done by rotating the elevating members 9a and 9b to move the elevating member 13 up and down. Incidentally, the operation may be performed by a motor instead of operating the handle 12. Further, in the embodiments described above, the corrugated board 1 was used as an example of the object to be inverted, but the object may be any other flat sheet-like object such as paperboard.

Effects of the Invention As described above, according to the present invention, when checking sheet-like objects such as corrugated boards one by one, it is possible to automatically turn over the sheet-like objects one by one, which improves work efficiency. You can measure your improvement.
