Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the provision of a device that can stack and stack stacked works, such as paper products, at high speed.

[0002]

[Prior art]

 Conventionally, for this purpose, for example, a work is placed on a conveyor, and one by one is taken out from the bottom by rotation of the conveyor, for example, a trade-in method as disclosed in US Pat. No. 4,991,831, or JP-A-59-20529 invented by the applicant, there is a horizontal take-out method which takes out a work in a vertical state as shown in FIGS. However, in the former method, the work is taken out from the gap between the conveyor and the roller provided opposite to it by rotating the conveyor. Problems such as overlap and clogging are likely to occur, and there is a problem for speeding up. In addition, even in the latter method of stealing, there is a limit to the number of sheets that can be picked up at high speed due to its mechanism.

[0003]

[Problems to be solved by the device]

 In this respect, the present invention provides a novel apparatus that can reliably stack stacked work pieces at high speed, and which has never existed before. For example, it is possible to check the quantity, take out one sheet, print it, and process it. It is suitable for use in the next step of, or for counting and stacking a fixed amount.

[0004]

[Means for Solving the Problems]

 However, in the configuration of the present invention, the stocker for stacking the works, the air jetting device for separating the stacked upper works, and the rotary transfer for sucking and transferring the uppermost work. The present invention relates to the provision of a one-piece work transfer apparatus characterized by comprising a separate member for providing a gap between the apparatus and one or more work pieces and less than two work pieces.

[0005]

[Action]

 The present invention is configured as described above, and separates the stacked works by the air blown onto the upper part of the work, and the separated works are sucked and transferred by a suction-type transfer device. A separate member provided with a gap of at least one work piece and less than two work pieces with the transfer device is configured so that one sheet can be reliably fed, thereby achieving high accuracy and high speed. It is possible to transfer and transport one sheet.

The structure will be described below with reference to the drawings.

【Example】

 FIG. 1 is a perspective view illustrating the configuration of the present invention, and FIG. 2 is a front view of the stocker portion illustrated in FIG. 1 as seen from the traveling direction. As shown in this figure, the structure is composed of a stocker 1, air injection devices 2 and 3, a rotary transfer device 4, and a separate member 5. The stocker 1 is composed of a receiving member 7 so that the workpieces 6 can be stacked, and side plates 8 and 9 connected to the air ejecting device in order to regulate both ends thereof, and contact type sensors 10 and 11 face the upper part thereof. Are provided at positions corresponding to both ears of the work. The sensor is a contact type having a rotating roller 13 at the tip of the elastically supported connector 12, and the switch 14 is turned on and off by the up and down movement of the elastically supported connector 12, and the operation of the switch 14 is received. The lifting devices 15 and 21 attached to the receiving member 7 are configured to be moved up and down individually by an air cylinder, a motor, etc. (not shown). That is, the elevating device 15 operates upon detection of the sensor 10, and the elevating device 21 operates upon detection of the sensor 11 (the description thereof is omitted because the relay circuit is conventionally used. ,) And maintain the horizontal state as shown in FIG. The configuration of the present invention is applicable to any work and any state, and is intended to always receive the action of the air injection described later under the same condition. The height of the work 6 (envelope) whose height is distorted when stacked due to the above has been corrected by raising the elevating device 21.

The air injecting devices 2 and 3 are provided in a face-to-face manner so that compressed air is ejected in the same direction as the traveling direction of the works and facing the upper part of the stacked work 6, and the air from the front and rear is provided. Upon receiving the jet, the central part floats up and rises up, so that accurate and reliable separation is possible. In addition, the rotary conveying device 4 has through holes 17 at regular intervals in the stretched rotating belt 16, and a negative pressure box 18 is provided inside the rotating belt 16, that is, in contact with the lower belt surface in particular. Has been. Further, the separate member 5 is stretched with a belt 19 made of, for example, silicon, which is robust against abrasion, and has a clearance of at least one work piece and not more than two work pieces with the rotary belt 16. is set up.

In the above structure, the stacked works 6 (envelopes in this example) are subjected to the action of the air sprayed from the air spraying devices 2 and 3 from the front and back of the stacked works 6 and several of the upper parts thereof are removed as shown in FIG. The uppermost one is floated, is sucked by the negative pressure box 18, and is adsorbed to the lower surface of the through hole of the belt 16 in a negative pressure state, and is continuously and sequentially conveyed as the belt rotates. At this time, since both ends of the workpiece floated by the air are pressed by the rotating rollers 13 of the contact type sensors 10 and 11, the positional deviation due to the air jet is unlikely to occur, and the opposite air jet causes the workpiece to move upward. As shown in FIG. 2, the work piece is curved in a curved shape and floats up, facilitating suction and conveyance.

Next, the workpieces that are adsorbed on the lower side of the conveyor belt and conveyed are separated into one sheet by the gap provided between the separate member 5 and the belt in the course of the conveyance. That is, in the separate member 5, the belt 19 is stretched in advance under a gap of at least one work piece and less than two work pieces. As the work progresses, the excess work is separated to the lower side, and the work that has passed through normally is transported and then adsorbed and transported. The separating member 5 is used as a belt mechanism because when it wears due to long-term use and causes an error, the belt stretched around is rotated and its position is set in the non-wearing portion. This is because it can be easily corrected by shifting. Therefore, the material is preferably a wear-resistant material such as silicon or synthetic rubber, and the separate member 5 itself can be a work of various thicknesses, that is, the gap can be easily changed as a whole. It is preferable that the device can be operated up and down by an appropriate means, for example, a gear, an air cylinder, a stepping motor or the like. Further, driving of a motor or the like may be used to change the position of the worn belt.

The work sucked and conveyed as described above is released from the suction action at its end, is released from the belt 16, and is transferred to the stocker or the like by the rotating transfer device 20. At this time, if a photoelectric counter 22 is provided on the transfer device 20 and the number thereof is counted, the number can be grasped, and the total amount can be checked and quantified easily.

[0011]

[Effect of device]

 The present invention has the above-described configuration, in which the upper work is sequentially floated by the compressed air injection device provided in the stocker part, and the work located at the top is adsorbed to the constantly rotating suction belt and continuously transferred. Since this method is used, it is possible to carry out high-speed and high-precision single-sheet transfer. Also, the target work can be applied not only to paper but also to plastics, and can also be used favorably for commercialized works such as envelopes, so various applications that require separation for each sheet It can be applied to a wide range of.
