2. Description of the Related Art Conventionally, as a packaging machine equipped with this type of transport pusher, for example, Japanese Patent Publication No. 62-34607 is known. 4 and 5 show the apparatus disclosed in the above-mentioned publication. In this conventional example, a conveyor 1 is shown.
Is transported by the first pusher-2 onto the table 3 on which the packaging by the tape T is performed, where it is pressed by the press plate 4 by the lowering of the press plate 4. The second pusher 5 slides on the table 3 to move to the packaging position. Immediately before the movement by the second pusher,
A tape of a predetermined length is vertically stretched in front of the laminate, and the tape is wound around three sides of the laminate by the movement of the laminate by the second pusher, and then the shutter 6 is lowered. Thus, a tape is also attached to the back surface of the laminated body, and the bottom surface is glued.

The transfer pusher according to the present invention is used, for example, as a first pusher in the above-mentioned conventional example. The conventional pusher-2 is suitable for extruding a laminate A as shown in FIG. A contact portion 7 made of a plate material of an appropriate size and a transport portion that moves the contact portion to move the laminate onto the table 3, and the transport portion is often constituted by an air cylinder 8. Was done. A guide rod 9 was provided in parallel with the air cylinder.

[0004] Such a conventional transport pusher, when the stacked body carried in by the conveyor 1 is stopped at a predetermined position by an appropriate stopper provided at that position, the stacked body is placed on a table. However, there is a problem as described below, since it is simply extruded.

[0005]

[Problems to be Solved by the Invention] For example, in the case of bookbinding by saddle stitching such as a weekly magazine, the binding side is considerably thicker than the opposite side, so that the stacking is alternately changed every several books and stacked. In the conventional push-out method, the binding side A1 protrudes from the side face as shown in FIG. 7 and the binding side A1 protrudes from the side face. It is impossible to realign even if touched. In particular, it is impossible to re-arrange items such as weekly magazines that do not have stiffness (rigidity).
There is a problem that desirable packaging without looseness cannot be performed.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art, and therefore, a pusher for transferring a laminated body such as a magazine to a predetermined position without unloading the laminated body. -To provide.

[0007]

The features of the transport pusher according to the present invention include a contact portion for pushing out the laminate and a transport portion for moving the contact portion, and the contact portion for pushing out the laminate is attached to the contact portion. In addition to the contact surface, a member such as a rod provided to be vertically movable and an actuator for moving the member up and down are provided.

[0008]

When the laminate is sent to the position of the pusher,
The pressing member in the abutting portion descends and presses the central portion of the upper surface of the stacked body, and presses the stacked body so as not to lose its load.
In this state, the transport unit operates to move the stack to a predetermined position, so that the stack can be prevented from being unloaded.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 show an example of a transport pusher according to the present invention. The pusher also includes a contact portion 10 for pushing out a laminate such as a book and a transport portion 20 moving the contact portion. The present invention is characterized in particular by the contact portion 10.

As shown more clearly in FIG. 2, the transfer pusher has a contact portion 10 preferably formed in a box shape, and a vertical front surface 10a serving as a contact surface for pushing out the laminate. A single rod 11 is provided on the contact portion so as to be vertically movable and preferably horizontally so as to press the upper surface of the laminate A, and the rod is moved up and down in the body of the contact portion. Actuating device 12 is provided. The rod 11 is provided with a reinforcing member 11a on the upper side thereof as required in order to increase its rigidity.

The operating device 12 may be any device or mechanism that can move the rod 11 up and down. In the illustrated example, a rodless cylinder is used. Reference numeral 13 denotes a movable portion of the air cylinder, to which the rod 11 is fixed horizontally. Therefore, in this embodiment, the actuator 12 is constituted by an air cylinder, but may be constituted by another mechanism such as a rack and pinion or a screw mechanism. The rod 11 and the actuator 12 enable the rod to press an intermediate position on the upper surface of the stacked body. In FIG. 2, reference numeral 14 denotes a stopper, which serves to stop the loaded laminate at a predetermined position.

In this embodiment, as shown in FIG. 1, the transporting section 20 for moving the abutting section 10 includes a screw rod 21 and a screw 22 which is fitted on the screw rod and fixed to the upper portion of the abutting section 10. ,
And a screw mechanism composed of a forward / reverse rotation motor 23 for rotating the screw bar forward / reverse. The contact portion 10 moves forward and backward by the forward / reverse rotation of the motor. The transfer unit 20 may also be configured by another device or mechanism such as an air cylinder.

As shown in FIG. 1, it is preferable to provide a holding plate 15 which moves forward and backward in relation to the transfer pusher.
Thus, the stack A can be moved while sandwiching the stack A between itself and the abutting portion 10 in the whole process or a part of the process of the stack. The holding plate 15 is operated by an air cylinder 16 or the like, and the operation is guided by guide rods 17 provided on both sides thereof.

This transport pusher is used, for example, as the first pusher 2 in the above-mentioned conventional example. In this case, when the stacked body A is carried into the position of the contact portion 10 by the conveyor, the operating device 12 By operation, as shown in FIG. 2, the rod 11 is lowered to the intermediate position on the upper surface of the laminated body and pressed, and in this state, the motor 23 operates to move the contact portion 10, and accordingly the laminated body is also moved. Move by slide,
In the case where the holding plate 15 is provided as described above, the holding plate 15 is further moved while sandwiching the laminated body between the holding plate 15 and the holding plate 15 that has been advanced in advance. -Move to a predetermined position on the bull.

Next, the rod 11 rises to release the laminated body, and the abutting portion 10 is returned to the original position via the screw mechanism by the reverse rotation of the motor 23. Therefore, it is possible to move while maintaining the state in which the load does not collapse, and finally, it is possible to perform packaging in a state where the load does not collapse as shown in FIG. Needless to say, the use of the transfer pusher is not limited to the packaging machine, and the pusher can be used for other uses for transferring the stacked body without unloading. In this embodiment, the rod is used as the pressing member. However, it goes without saying that another member such as a pipe or an elongated plate may be used instead.

In the above-described embodiment, the screw mechanism actuated by the motor 23 serves as a pusher for the laminate, but a servomotor can be used with such a structure. Therefore, the stack can be extruded at a low speed at the start of conveyance, and can be moved at a high speed at the time of empty movement, thereby enabling good conveyance.

[0017]

As described above, according to the present invention, the stacked body such as a book can be moved while the upper surface of the stacked body such as a book is pressed by the vertically movable member provided in the contact portion. , And can be transported in a state where the load does not collapse. Therefore, for example, by providing a packaging machine using a tape or the like, it becomes possible to package the laminate in a suitable state without unloading.
