Description
Technical Field
The invention belongs to the technical field of metal barrel stacking, and particularly relates to automatic metal barrel stacking equipment and an automatic metal barrel stacking method for changing stacks without stopping.
Background
As shown in fig. 1, the wall of a metal barrel (open metal can is also called metal barrel) is generally made of metal plate and is welded end to end into a cylindrical shape, and a ring-shaped convex ring 81 protruding outwards is formed on the upper edge of the metal barrel wall 84.
After the metal barrels are manufactured, the metal barrels need to be stacked up and down to save space, the process of stacking up and down is called stacking for short, and the stacked metal barrels are called stacking bodies for short. After stacking, most of the upper metal barrel in every two adjacent metal barrels up and down is inserted into the barrel cavity of the lower metal barrel, only the upper part is exposed, and the height of the exposed part is called the stack body level difference height for short, as shown by a dimension line h in fig. 2.
The prior automatic stacking apparatus is constructed substantially as shown in fig. 2: the barrel-holding clamp comprises a plurality of barrel-holding clamp blocks 1 which can be horizontally opened or horizontally embraced relative to the central axis m of a stack body, and a barrel-holding plate 9 which can vertically move and hold the stack body, wherein each barrel-holding clamp block 1 is correspondingly matched with a horizontal cylinder 11 which drives the barrel-holding clamp block 1 and the horizontal cylinder 11 to horizontally open and close, a first vertical driving mechanism which drives the barrel-holding clamp block 1 and the horizontal cylinder 11 to vertically move, and a second vertical driving mechanism which drives the barrel-holding plate to vertically move; the barrel supporting plate 9 is positioned below the barrel holding clamping block 1, as shown in fig. 2. The opening and closing means that each barrel holding clamping block is horizontally opened or closed; when the bucket holding clamp blocks are folded, the bucket holding clamp blocks are gradually close until the middle of each bucket holding clamp block can just contain a metal bucket to be stacked (the state is called a folding state), and after folding, the bucket holding clamp blocks can just clamp a stack body. When the barrel holding clamping blocks are opened, the barrel holding clamping blocks are far away from each other from a closed state. The mechanism for driving the barrel holding clamp block to horizontally open or close is called a horizontal opening and closing driving mechanism.
The stacking mode of the existing automatic stacking equipment is as follows: each barrel holding clamping block 1 holds the lowest one of the metal barrels 8 which are stacked into a pile, the holding position is positioned at the upper part of the metal barrel 8, then the barrel supporting plate 9 supports the new metal barrel 8 sent by the upstream horizontal conveying mechanism 4 upwards until the new metal barrel 8 supports the original stack body to become a component of the new stack body, then the barrel holding clamping blocks 1 are opened, simultaneously the first vertical driving mechanism drives each barrel holding clamping block 1 and the horizontal cylinder 11 to descend by a stack body level difference height h, then the barrel holding clamping block 1 holds the metal barrel 8 at the bottom of the new stack body, then the barrel holding clamping block 1 holds the new stack body to rise by a stack body level difference height, the barrel supporting plate 9 descends, and then the horizontal conveying mechanism 4 at the upstream of the production line sends a new metal barrel to the barrel supporting plate 9, and the process is circulated continuously; the path of the metal drum movement is shown by the arrows in fig. 2.
When the number of the metal barrels of the metal barrel stack reaches a set value, the stack body is carried away from the upper portion of the barrel supporting plate by the barrel holding clamp blocks, then the barrel holding clamp blocks are opened to lift off the stack body, and finally the barrel holding clamp blocks return to the upper portion of the barrel supporting plate, so that the barrel supporting plate can continue to receive the metal barrels brought by the upstream conveying line, the process is called stack replacement, and the barrel holding clamp blocks can continue to hold the metal barrels to form a new stack body after the stack replacement.
The existing stacking mode has the following problems:
in the process of stack changing, the barrel holding clamp blocks hold the original stack body to leave the upper part of the barrel supporting plate, and the stack body returns after being unstacked, so that the time consumption of the process is long, in addition, in the process, the barrel holding clamp blocks cannot receive a new metal barrel, and the barrel supporting plate cannot continuously receive the metal barrel brought by an upstream conveying line; this means that the stack cannot be continued during the change of stack, that the upstream mechanism for conveying the metal drums cannot convey the metal drums continuously, that all the stations upstream must be temporarily stopped, and that the stacking speed is reduced.
Disclosure of Invention
The invention aims to overcome the defects and provide automatic metal barrel stacking equipment for changing stacks without stopping, which has simple stacking action and high stacking speed and can continue stacking in the stack changing process.
The purpose can be realized according to the following scheme: the automatic stacking equipment for the metal barrel without stopping and stacking comprises a barrel supporting plate and a barrel supporting plate vertical driving mechanism, wherein the barrel supporting plate can vertically move and support the metal barrel; a first group of barrel holding clamping block assemblies are arranged above the barrel supporting plate, the first group of barrel holding clamping block assemblies are provided with a plurality of elastic barrel holding clamping blocks, and the vertical height positions of the elastic barrel holding clamping blocks are the same and are matched with each other to hold the stack body; the first group of barrel holding clamping block assemblies are also provided with a first horizontal opening and closing driving mechanism for driving the elastic barrel holding clamping blocks to open or close horizontally;

a horizontal longitudinal guide rail is fixedly arranged, a sliding support is arranged on the horizontal longitudinal guide rail, and the first group of barrel holding clamp block assemblies are arranged on the sliding support; the longitudinal driving mechanism is also arranged for driving the sliding support to move back and forth longitudinally along the horizontal longitudinal guide rail;
when the first group of barrel holding clamp block assemblies are driven by the longitudinal driving mechanism to reach the rear end of a longitudinal moving track of the first group of barrel holding clamp block assemblies and each elastic barrel holding clamp block of the first group of barrel holding clamp block assemblies is in a closed state, each elastic barrel holding clamp block of the first group of barrel holding clamp block assemblies is located above the barrel supporting plate.
When the elastic barrel embracing clamping blocks of the barrel embracing clamping block assembly are in a closed state, an upper angular point on the inner side of each clamping block body is closer to the central axis of the clamping block assembly of the barrel embracing clamping block assembly than a lower angular point on the inner side, and the direction of the elastic force exerted by the reset spring on the clamping block body is the direction of enabling the upper angular point on the inner side of the clamping block body to move towards the direction closer to the central axis of the clamping block assembly.
In the first group of barrel holding clamp block assemblies and the second group of barrel holding clamp block assemblies, each clamp block body can be rotatably arranged on the corresponding clamp block support through a horizontal rotating shaft, and when each elastic barrel holding clamp block of each barrel holding clamp block assembly is in a closed state, the horizontal rotating shaft direction of each clamp block body is tangential to a held stack body; each clamping block support is also provided with a limiting component for limiting the rotation amplitude of the clamping block around the horizontal rotating shaft; when the upper angular point on the inner side of the clamp block body is pressed downwards by the annular convex ring of the metal barrel, the resistance direction applied to the clamp block body by the limiting component limits the upper angular point on the inner side of the clamp block body to swing downwards.
In the first group of bucket clamping block subassemblies and the second group of bucket clamping block subassemblies, every clamping block body can be installed on corresponding clamping block support radially with sliding, and the clamping block body from top to bottom direction presss from both sides the clamping block support and forms the clamp rail of clamping block support.
A stacking plate and a stacking plate vertical driving mechanism for driving the stacking plate to vertically move are arranged in front of the barrel supporting plate; when the first group of barrel holding clamp block assemblies are driven by the longitudinal driving mechanism to reach the front end of a longitudinal moving track of the first group of barrel holding clamp block assemblies and each elastic barrel holding clamp block of the first group of barrel holding clamp block assemblies is in a closed state, each elastic barrel holding clamp block of the first group of barrel holding clamp block assemblies is located above the stacking plate.
And a metal barrel horizontal conveying mechanism for conveying the metal barrel to the barrel supporting plate is also arranged.
The inner side of the clamp block body refers to the side close to the central axis of the stack body when the stack body is clamped by the elastic barrel clamping block. The inner upper corner point of the clamp block body refers to a corner point which is located on the inner side of the clamp block body and on the upper portion of the clamp block body. The inner lower corner point of the clamp block body refers to a corner point which is located on the inner side of the clamp block body and located on the lower portion of the clamp block body.
By radial sliding is meant sliding in the radial direction of the stack being stacked.
The forward direction refers to the direction in which the stack is horizontally removed from above the pallet when the number of metal buckets stacked on the stack reaches a set number.
The central axis of the clamping block assembly is a vertical axis which is positioned at the center of each elastic barrel holding clamping block of the barrel holding clamping block assembly when the elastic barrel holding clamping blocks of the barrel holding clamping block assembly are in a closed state, and when the stack body is held by the elastic barrel holding clamping blocks, the central axis of the clamping block assembly is overlapped with the central axis of the stack body. When the elastic barrel holding clamping blocks of the barrel holding clamping block assembly are in a closed state, the elastic barrel holding clamping blocks are distributed by taking the central axis of the clamping block assembly as the center.
The invention has the following advantages and effects:
