Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a guide device for positioning a paper bundle in a width direction in a paper bundle punching machine for placing and punching a paper bundle on a slide base on a base.

[0002]

[Prior art]

 Conventionally, a centering mechanism for punching punches, which is disclosed in Japanese Utility Model Laid-Open No. 51-96691, is known. In the above mechanism, two paper guides having rack gears that can be expanded in the direction perpendicular to the longitudinal direction of the table are arranged in parallel on the back surface of the table of the punching punch. The two paper guides are connected by a pinion and a rack gear.

Next, the operation will be described. When a stack of paper is placed on the punch table and one of the paper guides is operated, the other paper guide is also operated by the engagement of the pinion and the rack gear. That is, when one of the paper guides is operated in the expanding direction, the other paper guide is also operated in the expanding direction. The operation of both paper guides causes the paper stack to be positioned at the center of the table. When not in use, retract the paper guide and store it on the back of the table.

[0004]

[Problems to be solved by the device]

 By the way, in the above-mentioned prior art, since each paper guide was connected with one pinion, the expansion width (expansion amount including the width of the table) of the paper guide is less than twice the width of the table. there were. Therefore, the effective usage of the paper guide was less than twice the width of the table, and the size of the paper to be punched was limited. In other words, only paper that is less than twice the width of the table can be used. It is also possible to make the paper guide longer to increase the amount of meshing with the pinion, but when storing the paper guide when not in use, one end of the paper guide protrudes from the table, which is aesthetically pleasing to store. Even at the top, it took a lot of space and was not very good.

[0005]

[Means for Solving the Problems]

 The present invention is intended to solve the above-mentioned problems, and two paper guides are slidably arranged in the width direction of the lower surface of the base, and drive members are attached to both guide members. Interlocking members that slide in opposite directions on both guide members are connected so that the inner ends of both guide members can be positioned outward beyond the center in the width direction of the base when the guide members are fully expanded. Characterize.

【Example】

 1 and 2 show a first embodiment of the present invention. Reference numeral 1 is a base, and two paper guides 2 and 3 are vertically slidably arranged in an overlapping manner in the width direction of the lower surface thereof. A drive plate 5 is vertically slidably mounted on a guide member 4 at the center of the back surface of the base 1, and racks 6 and 7 are formed on both sides of the drive plate 5. Racks 8 and 9 formed on one side of the perper guides 2 and 3 are engaged with pinions 10 and 11, and the racks 6 and 7 of the drive plate 5 are engaged with the pinions 10 and 11.

Next, the operation will be described. When the paper guide 2 is pulled out, the pinion 10 rotates left to drive the rack 6 downward, and the rack 7 rotates the pinion 11 right to drive the rack 9 left and slide the paper guide 3 outward. The paper guides 2 and 3 can be expanded outward until their inner ends reach the vicinity of the centers of the pinions 10 and 11.

FIGS. 3 and 4 show a second embodiment of the present invention. The paper guides 22 and 23 are arranged at the front and rear, pinions 26 and 27 are meshed with the respective racks 24 and 25, and the pinions 26 and 27 are connected by a connecting rod 28 in a lateral direction.

Next, the operation will be described. When the paper guide 22 is pulled out, the rack 24 rotates the pinion 26 counterclockwise, the connecting rod 28 rotates the pinion 27 counterclockwise, the rack 23 is moved outward, and the paper guide 23 is slid outward. To do.

FIGS. 5 and 6 show a third embodiment of the present invention. The paper guides 32 and 33 are vertically stacked, the respective pinions 36 and 37 are meshed with the respective racks 34 and 35, and the pinions 36 and 37 are obliquely connected by the connecting rod 38.

Next, the operation will be described. When the paper guide 32 is pulled outward, the rack 34 rotates the pinion 36 counterclockwise, the connecting rod 38 rotates the pinion 37 clockwise, the rack 35 is moved outward, and the paper guide 33 is slid outward.

7 to 9 show a fourth embodiment of the present invention. The paper guides 42 and 43 are arranged at the front and rear, and pins 44 and 45 are provided at both ends of the mounting so as to be slidable in the width direction. Reference numeral 46 is a connecting rod whose center is pivotally connected by a shaft 47, and the pins 44 and 45 are fitted in the long grooves 48 and 49 on both sides.

Next, the operation will be described. When the paper guide 42 is pulled outward, the pin 44 slides inward in the long groove 48, and the connecting rod 48 is rotated leftward, and the pin 45 of the paper guide 43 is pushed outward by the long groove 49. , The connecting rod 48 is vertical as shown in FIG. 8, and when the paper guide 42 is further pulled outward, the connecting rod 46 is further rotated to the left as shown in FIG. Stop and expand to the maximum.

[0014]

[Effect of device]

 In the present invention, two paper guides are slidably arranged in the width direction of the lower surface of the base, and drive members are attached to both guide members, and both guide members are slid in opposite directions. When the guide members are fully expanded, the inner ends of the guide members can be located outwardly beyond the center in the width direction of the base, so that the size of the base is more than twice the size of the base. It can accommodate paper, and when the paper guide is stored, one end of the paper guide does not protrude from the base.
