Abstract

PURPOSE:To carry out sheets of paperboard as a lump by installing a projecting piece, projected high incrinatorily, in and around a tip of a carry-in conveyor, while dropping plural sheets of paper board on the conveyor, which pushed a base arm out, from the projecting piece, and pushing this projecting piece forward with a pusher. CONSTITUTION:A carry-in conveyor 10 is made tiltable to some extent, and a projecting piece 31 projected inclinatorily is shiftable installed in and around its tip part by a pusher. A sheet of paperboard (a) mounted on the carry-in conveyor 10 gets over an incline of the projecting piece 31 and is stacked on a step part of the projecting piece 31 in succession after the conveyor 10 is made into a tilted state and pressed by a base arm 21. Then, the projecting piece 31 is pressed by the pusher, and the paperboard (a) stacked in pile on the step part is transferred to a carry-out conveyor 34 as a lump and taken out. Consequently, since the paperboard is conveyed surely after being separated one by one in a lump, no trouble happens there.

Description

[Detailed description of the invention] [Industrial application field] The present invention is a machine for producing paperboard such as corrugated paper and cardboard.

This relates to a transport device for paperboard to be fed to a printing machine or the like.

[Prior Art] A device for stacking and feeding paperboard such as corrugated paperboard cut to a predetermined size and stacked into a hopper for the purpose of printing or manufacturing has already been disclosed in Japanese Patent Application Laid-Open No. 50-486.
Publication No. 64, Japanese Patent Publication No. 52-27898, Japanese Unexamined Patent Publication No. 52-27898
This is already known from Japanese Utility Model Publication No. 4-149176, Japanese Utility Model Application Laid-open No. 61-15940, and the like. However, these conventional transfer devices were only able to send out the paperboard one after another in a constant wrapped state. However, depending on the circumstances of a printing machine or the like, it may be necessary to feed, for example, 20 to 30 sheets in one batch.

In that case, with the above-mentioned conventional transfer device, the carry-in conveyor is slightly moved while the carry-out conveyor is stopped, and when the block of 20 to 30 sheets has been transferred onto the loading conveyor, the carry-out conveyor is moved and the block is sent out. I had no choice but to
Then, the paperboard that has stopped straddling the tip of the carry-in conveyor and the starting end of the carry-out conveyor will be shifted back and forth under the block as the carry-out conveyor is driven, and will be carried out in that state, so that the paperboard will be transferred to the next machine. There was a risk of trouble occurring during the preparation process.

[Object of the Invention] The present invention aims to solve the above-mentioned drawbacks and to provide a transfer device that can reliably feed paperboard in one block, thereby eliminating the risk of trouble.

[Means for achieving the object] In order to achieve the above object, the paperboard transfer device of the present invention has the following features:
A carry-in conveyor is tiltably provided on a machine base so as to be able to tilt from a vertically standing position to a forward-leaning position; It consists of a carry-out conveyor installed at
A projecting piece is fixed near the tip of the one-person conveyor in the form of an inclined surface that gradually protrudes higher than the conveying surface and consists of a slope part on which the paperboard rides, and a cliff-like step part continuing to the slope part, and the projecting piece A pusher is provided at the bottom of the step to push forward a block of paperboard that has fallen from the step, and the paperboard pushed by the pusher is carried out as a block by the carry-out conveyor. be.

[Operation] By moving the base arm forward, the paperboard that has climbed onto the projecting piece is caused to fall from the stepped part, and by pushing the fallen paperboard further by the pusher, the block of paperboard is completely separated from the following paperboard and transferred to the conveyor. Transfer it above.

Reference numerals 57a and 57b are cylinders provided on the machine base 1 to perform the tilting movement, and the piston rond ends of the cylinders are connected to fixed pieces 58a and 58b on the lower surface of the discharge conveyor.

Note that the endless belts 53a, 53b, 54a,
The outer peripheral surface of 54b is uneven to prevent slipping.

In the paperboard turning and transferring apparatus constructed in this way, the paperboards a are stacked on the stand arm 21 with the rotating frame 5 in a vertically standing position as shown in FIGS. 1 and 2. Then, by actuation of the cylinder 8, the rotating frame 5 is tilted into a forward leaning position as shown in FIGS. 3 and 4. Then, in this position, the carry-in conveyor 10 is driven to advance the platform arm 21. The paperboard a is pushed forward as shown in FIG.
The projecting piece 31 degrees rides on the slope part 31a of 31 and is further pushed, and several to several dozen sheets of paperboard a' fall down the stepped part 31b and are remounted on the conveyance surface 19.6 Thereupon, the carry-in conveyor 109 arm 21 is stopped, and then the cylinder 32 is actuated to move the pusher 33 forward, pushing forward the block of paperboard a' that has fallen from the step 31b as shown in FIG. As shown in FIG. 7, the cylinder 47 is actuated to rotate the support shaft 43 via the arm 46, and the bearings 44a and 44b are pivoted upward about the support shaft 43, thereby moving the pulleys 45a and 45b upward. The endless belts 54a, 54b are made to protrude above the conveying surface 19, and the block of paperboard a' is supported on the endless belts 54a, 54b.
The endless belt 5 is rotated by the drive of the motor 49.
4a, 54b and endless belts 53a, 53b, the block of paperboard a' is carried out as shown in FIG. In this way, the carry-out conveyor 34 can carry out the paperboard a as a lump. At the same time, the arm 21 of the carry-in conveyor 101 is advanced to push the paperboard a by a required amount and drop it from the stepped portion 31b, and by operating the pusher 33, the block of paperboard is separated from the following paperboard and placed on the carry-out conveyor 34. It can be transferred. By providing the protruding piece 31 in this manner and allowing the protruding piece to ride over the protruding piece 31, the paperboard can be reliably separated into blocks. That is, as the paperboard in the polymerized state is pushed out, it falls under its own weight from the stepped portion 31b to form a step with the following paperboard, and by pushing the lump with the pusher, the lump is reliably placed on the carrying-out conveyor 34. This means that the paperboard will not be wrapped in a half-finished state.

Although not shown, the endless belts 54a and 54b on the outer periphery of the pulleys 45a and 45b are covered with a conveying surface 19 due to falling.
A cover is provided to prevent unnecessary contact with the paperboard remounted on top.

Note that by operating the cylinders 27a and 27b and rotating the carry-in conveyor 10 using the upper end of the rotating frame 5 as a fulcrum and lifting the rear part, the carrying surface 19 of the carry-in conveyor 10 is lifted.
It is also possible to make the front downward.

[Effects of the invention] As described in the embodiments above, the paperboard transfer device of the present invention is provided with a protrusion and a pusher near the tip of the carry-in conveyor, and the pusher pushes the paperboard that has climbed over the protrusion. By transferring the stacked paperboard onto the carry-out conveyor, it is possible to reliably divide and feed a block of overlapping paperboard into blocks, thereby allowing paper feeding to be carried out without the risk of trouble.
