Description

DETAILED DESCRIPTION OF THE INVENTION Asphalt 1 to latex are stored and shipped in paper bags at factories. The paper bag is stored in a transport can made of gold 1i and transported to the lower part of the injector by a conveyor, and after being filled with asphalt 1 to milky lotion, it is also sent to the sealing position by a conhair and sealed by a sewing machine. Thereafter, a predetermined plurality of cans are transferred onto a pallet by a dumping device, and then transported together with the pallet to a storage location by another conveyor.

Conventionally, in the above-mentioned dumping device, the transport can is supported by the Tisopuru, the Tisopuru is rotated and moved forward, the can is tilted and moved onto the pallet, and then the Tisopul is returned and rotated and retreated to transport the can. A device is known in which the paper bag is extracted from the transport can by returning and transferred onto a pallet. However, in the past, paper bags were transferred to pallets after they were stopped in a predetermined position.
Since the paper bag is heavy with asphalt emulsion filled in it, when the transport can is raised and returned, a part (bottom) remains inside the transport can, and the remaining part touches the rim of the transport can. After being lifted while making sliding contact, the paper bag is completely pulled out of the transport can and falls onto the pallet, and the paper bag is damaged due to sliding contact with the rim of the transport can while being lifted or the subsequent fall. The asphalt emulsion is easily damaged by the heat of the asphalt emulsion), and the asphalt emulsion leaks.

The present invention is designed so that when a melt-filled bag such as the above-mentioned paper bag is pulled out from a transport can and transferred to a pallet, one can-carry can be smoothly pulled out without the bag being lifted as the transport can returns. and the above drawbacks)W
The feature is that the conveyor, which carries pallets only within a predetermined transport range at the transshipment position, is configured to move forward and backward relative to the chisopuru by actuating the actuator, and to move the conveyor forward and backward in synchronization with the return movement of the transport cans. This is because the pallets are moved apart.

An embodiment of the present invention will be described in detail below based on the drawings.

In FIG. 1 (side view) and FIG. 2 (front view), the Chisopuru 1 is constructed by connecting left and right disks 2 facing each other by a plurality of horizontal rods 3, and is vertically installed below the running frame 4. The left and right shafts 6 are rotatably mounted between the left and right bearings 5.

The traveling frame 4 is straddled between the left and right beams 8 installed on the support columns 7, and horizontally travels back and forth on the beams 8 in a self-propelled manner. That is, when the hydraulic cylinder 9 mounted on the traveling frame 4 is activated and the two racks 10 connected to the piston rods slide forward or backward, the rotation transmission mechanism equipped on the traveling frame 4, that is, These racks 1
0, its rotating shaft 12, left and right gears 13 fixed to both left and right ends of this rotating shaft 12,
Separate left and right gears 14 meshing with these gears 13, and left and right wheels 1 that share a common shaft 15 with these gears 14.
6 and the left and right pinions 17 rotate, and these left and right pinions 17 mesh with the left and right ranks 18 laid on the left and right beams 8, respectively, so that the left and right wheels 16 are laid on the beams 8. The traveling frame 4 rolls on the left and right bars 19, and moves forward (in the direction of arrow a in FIG. 1) or backward.

In addition, the rank 20 fixed downwardly to the left and right beam members 8 is meshed with the pinion 21 supported by the left and right bearings 5, and the left and right pinions 22 coaxial with the pinion 21 are connected to each other. 1 left and right disk 2
Because it is engaged with the arc-shaped rack 23 provided on the outer peripheral edge of the chino pulley 1, when the traveling frame 4 moves forward,
It rotates in the direction indicated by the arrow in the figure, and when the traveling frame 4 retreats, the chino pulley 1 returns to rotate in the direction opposite to the direction indicated by the arrow.

Each of the left and right disks 5 of the chisoburu 1 has a vertically elongated window hole 24.
A can positioning roller conveyor 25 is installed between these discs 5.

A single-vessel speed can 27 containing a paper bag 26 filled with asphalt emulsion is transported into the present dumping device by the roller conveyor 28 for carrying cans and placed in a circle S2 on the right side in Fig. 2.
The cans pass through the window holes 24 and are placed on the can positioning roller conveyor 25 between the front and rear horizontal rods 3 of the Chisopuru 1. When it is detected that a predetermined number of TA conveying cans 27 are mounted on the roller conveyor 25, the hydraulic cylinder 9 is extended, the traveling frame 4 moves forward, and the Tisopuru l rotates in the direction indicated by the arrow. Since the convex portions 29 protruding from the front and rear surfaces of the transport can 27 engage with the horizontal rods 3, the conveyance can 27 is lifted by the rotation of the chisopuru 1 and moved forward together with the chisopuru 1 while lying down to the front side.

On the other hand, in front of the Chisopuru 1, a roller conveyor 30 for pallet positioning is installed on a traveling frame 31. The running frame 31 has wheels @ 34 that roll on rails 33 laid on a base frame 32 as shown in Fig. 32 toward Chisopuru 1 or backwards, and the passing seat stops at the position (original position) trailing behind Chisopuru 1, as shown by the solid line in Figure 1.

The roller conhair 30 loads 111 MI of pallets 36 sent in by the roller conhair 37 for the 1M barrette at the above-mentioned original position.

When the hydraulic cylinder 9 extends and the Tisopuru 1 rotates as described above and moves forward, the air cylinder 35 simultaneously extends and the roller converter 30 moves toward the Tisoplu 1 with the pallet 36 on it as shown in the chain line in FIG. The paper bag 26 inside the transport can 27 slides and gradually protrudes from the transport can 27, and a portion (of the transport can 27) moves forward as shown in FIG. (a portion protruding from the upper surface opening) is brought into contact with the upper surface of the pallet 36. The hydraulic cylinder 9 is contracted, and the Sennopuru 1 moves backward while rotating, and the 1 canister 27
At the same time, the air cylinder 35
The paper bag 26 is moved by the pallet 36 in the opposite direction to the moving direction of the shipping can 27, and is lifted by the transport can 27. It is pulled out smoothly and placed on the pallet 36.

When Disople 1 returns to its original position, the empty transport can 2
7 is transferred to the can dispensing roller conhair 38 (FIG. 2) through the window hole 24 of the disk 2 on the left side of the disople 1, and when the roller conhair 30 returns to its original position, the pallet 36 carrying the paper bag 26 is transferred to the can output roller conhair 38 (FIG. 2). It is transferred to the roller conveyor 39 for carrying out (FIG. 3).

Note that the reference numeral 40 in FIG. 1.3 is a bag stopper installed on the traveling frame 31 to prevent the paper bags 26 transferred onto the pallet 36 from falling. Also, 4
1 is a sprayer attached to the stopper 40, which sprays water onto the paper bag 26 on the pallet 36.

As described above, according to the dumping device of the present invention, the pallet can be moved away from the container together with the container in synchronization with the return movement of the transport can, so that the melt filling bag, such as a paper bag filled with asphalt emulsion, etc. ,) The bag can be pulled out smoothly as if it were being pulled out of the shelled can, and there is no need for the bag to be lifted and damaged when the can is returned to its original state, unlike in the past.
