Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a dumping device for bags filled with melted material, which transfers bags that have been carried in while being housed in a transportation can from the transportation can onto a pallet after being filled with a melted material such as asphalt emulsion.

[Conventional technology]

Conventionally, this type of dump device was
The one described in Publication No. 4878 is known. This dump device is equipped with a tipper and an air cylinder on a running trolley that runs on rails laid on the floor, and transmits the linear motion of the piston rod of the air cylinder to the front and rear drive gears on the running trolley via a chain. The rotation of the rear drive gear is transmitted via the transmission gear to the disk of the chippla to rotate the chippla, while the rotation of the front drive gear is further transmitted via the chain to the disk of the chippla fixed to the axle of the traveling bogie. The transmission is transmitted to a traveling pinion, and the traveling pinion is caused to roll against a rack laid on the floor, thereby moving the traveling truck forward and backward. Then, as the traveling truck moves forward, the chipper is rotated forward, and the transport can supported by the chipper is transported.
The conveying can is tilted downward toward the stopped pallet, and the melt filling bag contained in the conveying can is transferred onto the pallet in a fixed position.

[Problem to be solved by the invention]

However, this method had the following drawbacks. Since the drive mechanism that drives the chipper is located below the chipper, the drive mechanism is contaminated by the melt that leaks when the bag is damaged, and cleaning it requires a great deal of time and effort. The dump device has a structure in which the Chitsupura and its drive mechanism are mounted on a running trolley that runs on rails laid on the floor, and the entire dump device moves forward and backward on the floor. Special consideration must be given to the installation and support of these conveyors to avoid collisions with them and the conveyors carrying the pallets. The weight of the Chitsupura, its drive mechanism, transport cans, molten material, etc. is all supported by a traveling truck, and the traveling pinion fixed to the axle of this traveling truck is rolled against a rack laid on the floor to transport the entire dumping device. It requires a large amount of power to move forward and backward. Since the melt filling bag is transferred onto the pallet while the pallet is held in place, if the bag is a paper bag and the melt filled in it is asphalt emulsion at about 200℃, the filled asphalt emulsion is soft and heavy. Because the bag is an object, a part of the bag (bottom) remains inside the can when the can is raised and returned to its original position, and the remaining part slides against the rim of the can and is lifted up. The paper bag, whose strength has weakened due to the heat of the asphalt emulsion, will be completely pulled out of the can and fall onto the pallet. There were cases where the asphalt emulsion leaked out due to damage. An object of the present invention is to provide a dump device that can eliminate these conventional drawbacks.

[Means to solve the problem]

The feature of the dumping device of the present invention, which will be explained with reference to the illustrations in the drawings, is that it employs the following configuration. The Chitsupura is rotatably mounted between left and right bearings 5 vertically installed on a running frame 4, and this running frame 4 has wheels 16 that roll on left and right rails 20 installed horizontally. A pinion 11 is pivotally supported on the traveling frame 4 and meshes with a rack 10 that is moved back and forth by a piston rod of a cylinder 9 mounted thereon.
The rotation of the pinion 11 is transmitted to the wheels 16 through the gears 13 and 14, and the running frame 4 is moved forward and backward by the operation of the cylinder 9. A pinion 21 that meshes with a rack 20 fixed to a rack 20, and a gear 22 that is coaxial with the pinion 21 and meshes with teeth 23 on the outer periphery of the disk 2 of the chip pla are supported, and the pinion 21 rotates as the traveling frame 4 travels. The rotation is transmitted to the chipper, and a pallet conveyor 30 for carrying the pallets within a predetermined conveyance range on the left and right is installed in front of the chipper on a conveyor support cart 31. horizontal rail 33
The conveyor support cart 31 has wheels 34 that roll on the top and is capable of running back and forth along the rails 33.The conveyor support cart 31 has wheels 34 that roll on the top and is capable of moving forward and backward along the rails 33. A cylinder 35 is connected to the cylinder 35, which causes the traveling frame 4 to move away from the chip in synchronization with the retreat of the traveling frame 4.

[Effect]

According to such dump equipment, Chitsupura is
It is suspended by a running frame that runs on an installed rail, and when the running frame moves forward or backward, it moves forward or backward as a unit while rotating beneath it. When the Chitsupura moves forward and rotates, tilting the transport cans downward and moving them forward, the conveyor support cart is moved forward toward the Chitsupura in synchronization with this, and the pallets on which they are loaded are moved forward. It approaches the conveyor can along with the conveyor. On the other hand, when the Chitsupura rotates while retreating and returns the conveyed cans, the conveyor support cart is simultaneously moved backwards with respect to the Chitsupura, and the pallets are moved in the opposite direction to the conveyed cans. The bags contained in the transport can are transferred onto the pallet so as to be pulled out from the transport can by the pallet.

8, the left and right wheels 16 are engaged with the left and right rails 19, which are also laid on the left and right beams 8.
The traveling frame 4 moves forward (in the direction of arrow a in FIG. 1) or backward. In addition, left and right racks 20 fixed downwardly to the left and right beams 8 are engaged with left and right pinions 21 supported by left and right bearings 5, and the left and right racks 20, which are coaxial with the pinions 21, are engaged with each other. The pinion 22 is connected to the tooth 23 provided like an arc-shaped rack on the outer periphery of the left and right discs 2 of the chip 1.
It is meshed with Therefore, when the traveling frame 4 moves forward, the chipper 1 rotates in the direction of arrow b in FIG.
Further, when the traveling frame 4 retreats, the chipper 1 returns and rotates in the direction opposite to the arrow b. A vertically long window hole 24 is provided in each of the left and right disks 5 of the chip 1. Further, a can positioning roller conveyor 25 is fixedly installed horizontally at a predetermined position between these left and right disks 5. In FIG. 2, the transport can 27 containing the paper bag 26 filled with asphalt emulsion is sent to the present dumping device by the can transport roller conveyor 28, passes through the window hole 24 of the disk 2 on the right side, and is transferred to the chippura 1. The cans are placed on the can positioning roller conveyor 25 between the front and rear horizontal rods 3. When a sensor (not shown) detects that a predetermined number of transport cans 27 have been placed on the roller conveyor 25, the hydraulic cylinder 9 is extended and the traveling frame 4 moves forward, and the chipper 1 is moved forward. Rotate in the direction of arrow b. In this case, since the convex portions 29 protruding from the front and rear surfaces of the transport can 27 engage with the horizontal rods 3, the transport can 27 is lifted by the rotation of the chipper 1 and moves forward together with the chipper 1 while lying down on the front side. On the other hand, in front of the chipper 1, a pallet roller conveyor 30 is mounted on a conveyor support cart 31. This conveyor support cart 31 is

【Effect of the invention】

The dumping device of the present invention has the following effects. Since the drive mechanism that drives the chippura is located above the transport can supported by the chippura, it is driven by the melt that leaks when the bag breaks, unlike in the past when the drive mechanism was located below the chippura. This eliminates the problem of the mechanism becoming contaminated and requiring a great deal of time and effort to clean it. Since the entire driving mechanism for driving the chipper is installed and the chipper is suspended, it becomes easy to arrange the conveyor for transporting cans and the conveyor for transporting pallets. Since the traveling frame is made to be able to travel along the constructed rails, and the chippla is mounted on a bearing that is vertically installed on the traveling frame, the power required is reduced compared to the conventional one. In order to synchronize with the return movement of the transport can and move the pallet away from the conveyor,
The melt-filled bag can be pulled out smoothly as if it were being pulled out from the transport can, and the conventional problem of the bag being lifted and damaged when the transport can returns is eliminated.
