Description

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

The present invention relates to an automatic seamer device that manufactures metal packaging containers for packaging solid products such as confectionery, other appropriate items, powders, liquids, etc. The metal base plate (hereinafter referred to as the base plate) that is combined with the
This invention relates to a feeding device that automatically and sequentially feeds can bodies to appropriate positions.

[Prior art]

When supplying can bodies and main plates to the processing section of this type of automatic seamer device, the can bodies are placed and conveyed on a conveyor belt at appropriate intervals, and the main plate is accurately placed on top of the can bodies. We are transporting and supplying the products. However, although the can body can be placed on the conveyor belt automatically, the supply of the base plate to the top of the placed can body is easy to slip because both members are metal plates, and it is technically difficult to do this automatically. This is difficult and has traditionally been done mostly by hand.

[Problems to be solved by the invention]

However, as in the conventional example above, where the main plate is manually supplied by workers, there is not only the problem of rising labor costs, which also affects the product, resulting in higher manufacturing costs. While the machine is in operation, workers must be on hand to carry out supply work, and there are restrictions on working hours, so full automation is not possible, such as not being able to mass-produce by operating only the automatic seamer device. In addition to this, there were also problems such as a lack of safety, such as the possibility that workers would injure their hands from the edges of the base plate while working.

[Means for Solving the Problems] The present invention aims to solve the above problems, and provides a lift mechanism in an upright state that is equipped with a lift platform that lifts up a predetermined amount of base plates stacked on a base. , a pooling mechanism for temporarily pooling a predetermined amount of the lifted up base plate is provided at approximately the middle position of the lift mechanism in the upright state, and a pool mechanism is provided at the top of the pool mechanism to collect the pooled base plate one by one. An arm mechanism including a guide rail with a magnet and a conveyor belt for intermittently transferring is arranged to protrude from the lift mechanism by a predetermined length toward the rear side, and the protruding tip side of the arm mechanism is arranged to correspond to the size of the base plate. A stopper member whose supply position can be adjusted freely is provided, a sensor for detecting the presence or absence of a base plate is attached to the stopper member, a drop mechanism for the base plate including a magnetic holding member is provided to the arm mechanism, and the pool mechanism A vertically movable vacuum suction member for suctioning the main plate is disposed above the arm mechanism and between the guide rails of the arm mechanism.

In this case, the number of pooled base plates A is several tens, and when the number of pooled base plates becomes small, this is detected by a detection means such as a limit switch, and the lift platform 17 is raised in the same manner as described above. Replenishment will be carried out sequentially. Therefore, the lift table 17 is configured not to descend to the lowest position but to stand by at a substantially intermediate position so that the next replenishment operation can be easily performed. An arm mechanism 31 is disposed on the top of the pool mechanism 26 so as to protrude a predetermined length from the lift mechanism 2 toward the back side. This arm mechanism intermittently transports the base plates A pooled in the pool mechanism 26 one by one and supplies them to the target position, and a pair of guide rails 32 and 33 are arranged at a predetermined interval. magnets 34, 3 of a predetermined length are attached to the bottom surface of the magnets 34, 3.

It is fixed in a predetermined position by a bolt 45. Furthermore, a sensor 46 is attached to the stopper member 41 to detect the presence or absence of the base plate A, and the sensor 46 detects whether the base plate A is present or not, and when the base plate A conveyed by the conveyor belts 36 and 37 is at a predetermined position, that is, when it approaches or contacts the stopper member 41. In addition to detecting whether or not the base plate A is in the correct position, it also drives a dropping mechanism, which will be described later, in a timely manner, thereby contributing to holding the conveyed base plate A and supplying it to an appropriate position. A dropping mechanism for the base plate A is disposed between the guide rails 32 and 33. The dropping mechanism includes a plate-shaped holding member 47 disposed at a position substantially corresponding to the level position of the transport belt located below the transport belts 36 and 37, and the holding member 47 is attached to a rod 49 of an air cylinder 48, for example. It is fixed to the tip of the air cylinder 48 and can be selectively moved up and down by driving an air cylinder 48. And the holding member 4
In order to move up and down appropriately, a guide rod 50 is attached to the upper surface of the arm 7, and the guide rod is slidably supported by a bearing mechanism 51 attached to the frame of the arm mechanism. This holding member 47 holds tip magnets 34a and 35a separated from the magnets 34 and 35. Furthermore, a guide plate 52 is disposed on the outside of the guide rails 32 and 33, and the guide plate is attached to a boss member 54 through a slit-shaped guide hole 53 and connected to a handle shaft 56 via a stay 55. , by operating the handle 57, adjustment is made in accordance with the width direction of the base plate A. A vacuum suction member 58 such as an air cylinder that moves up and down is provided above the pool mechanism 26 and between the guide rails 32 and 33, and a holder 59 made of a suction cup-like elastic material is attached to the tip of the vacuum suction member 58 for suction. In addition to stabilizing it, it also prevents damage to the base plate A. The vacuum suction member 58 is connected to a suitable vacuum generator via a pipe or hose.
When it descends, it acts as an adsorbent, and when it rises, the adsorption is released. Therefore, the vacuum suction member 58 descends, and the holder 59 at its tip
When the main plate A is close to the main plate A, an adsorption action occurs and the main plate A is attracted and rises, and the main plate A is almost connected to the conveyor belt 3.
The attraction action is released when the conveyor belts 34, 37 are in contact with each other, but the magnets 34, 3 attached to the guide rails located inside the conveyor belts 36, 37
5, the base plate A is held by suction and will not fall. The base plate A, which has been attracted by the magnets 34 and 35 via the conveyor belts 36 and 37, is moved to the conveyor belts 36 and 3 by the drive of the servo motor 40.
7 is driven, the magnets 34a, 3 are transported while maintaining the suction position, and the tip magnets 34a, 3 are moved at the position where the main plate A is in contact with the stopper member 41.
5a, and at this position, the base plate A is supplied to a position set in cooperation with the dropping mechanism. The handle 60 is used to adjust the position of the arm mechanism 31 by moving it up and down together with the pool mechanism 26, the handle 61 is used to adjust the position of the stopper member 41, and 62 is used to adjust the position of the stopper member 41.

The automatic base plate feeding device for carrying out the apparatus of the present invention having the above-mentioned configuration stacks and places a predetermined amount of base plates A on the guide rails 4 and 5 of the conveyor mechanism 3 as shown in the first and second figures. If this is done, the chain 6 will be driven by the motor 8, and the pawl 11 attached to the chain will engage the base plate A and transfer it to the lift mechanism 2 side. Either the base plate A is already placed on the lift table 17 of the lift mechanism 2, or the base plate A is waiting in front of the lift table 17 while the lift table 17 is rising, and the lift table 1
When the main plate A disappears above 7 and descends, the motor 8
is driven to supply a predetermined amount of the base plate A onto the lift table 17. Next, the base plate A supplied onto the lift table 17 is supplied in a predetermined amount to the pool mechanism 26 as the lift table 17 rises. In this pool mechanism 26, when a predetermined amount of the base plate A still remains, the lift platform is on standby during the ascent, and when a signal is received from the pool mechanism 26 requesting replenishment due to the low amount remaining, the lift platform 17 rises to supply and replenish a predetermined amount of the main plate A. Therefore, from the conveyor mechanism 3 to the pool mechanism 26, sufficient replenishment can be performed without disturbing the base plate A. In addition, the base plate A pooled in the pool mechanism 26 is
The vacuum suction member 58 attracts and lifts the sheets one by one, the magnets 34 and 35 of the arm mechanism 31 adsorb them, and the conveyor belts 36 and 37 transport and supply them to the protruding end side, and the tip magnets 34a and 35
It is temporarily adsorbed and held by a and then supplied to a predetermined position. In this case, the servo motor 40 drives the can body 63 to be fed to a known automatic seamer device (not shown) at the timing when the can body 63 is conveyed by the conveyor belt 62 as shown in the first figure. The air cylinder 48 operates at the timing when the body 63 is positioned directly below the arm mechanism 31, and quickly raises the holding member 47 to separate the tip magnets 34a and 35a from the main plate A, thereby exerting the attraction force. By making the main plate A disappear, the can body 63
I try to drop and place it accurately on top of it. Then, a sensor 46 attached to the stopper member 41 detects that the base plate A has fallen, that is, that the base plate A has disappeared from the suction position, and issues a predetermined signal, which is applied to the drop mechanism. , thereby driving the air cylinder 48,
The holding member 47 descends and waits at a position where it can adsorb the conveyed base plate A, and repeats the above operation to quickly and accurately feed the base plate A one by one to a predetermined position. Further, the conveyor belts 36 and 37 are not continuously driven, but the vacuum suction member 5
8, and is driven intermittently in synchronization with the timing of conveyance of the can body by the seamer device.
