This relates to a transfer device that moves a caster pallet with boxes stacked at the product completion site to a required location and transfers the products stored in the product boxes to a receiving means such as a belt conveyor or packaging machine. .

[Technical background of the invention and its problems]

Conventionally, as mentioned above, the work of transferring the products stored in the product boxes stacked on the caster pallet to a receiving means such as a belt conveyor or packaging machine, and the work of transporting the empty product boxes to the The reality is that a series of operations, such as loading onto star pallets, are all performed by input.

In this way, performing a series of transfer operations by inputting data causes worker fatigue due to the weight of the product boxes containing the products, and as fatigue accumulates, work efficiency decreases and labor costs are high. However, it had the disadvantage of high work costs.

[Purpose of the invention]

In order to eliminate the above-mentioned drawbacks of the conventional transfer work, the present invention requires a transfer device that has a moving means, a pushing means, a receiving plate means, and a supporting means operated by mechanical power, so that no human power is required. The purpose of this is to enable the transfer work to be carried out at low cost by carrying out the work with high efficiency.

[Embodiments of the invention]

In the following, the present invention will be described in which a large number of record discs housed in shelves, paper bags, etc. are stored one on top of the other, and are transferred from product boxes stacked on a caster pallet onto a belt conveyor serving as a receiving means. An example of a transfer device will be described.

There are several through holes B ₁ in the bottom of the product box B, which contains a large number of stacked records (hereinafter referred to as product A) stored in paper bags, etc.
is drilled.

This product box B is stacked in multiple stages on the caster pallet C, and is placed in the caster pallet chamber 2 of the underframe 1.
A belt conveyor D is installed on the other side of the underframe 1 to convey the product A to the next process. Also caster palette C
A stop bar 3 is installed at a height that corresponds to the side surface of the lowest product box B loaded on the tray, and separates the caster pallet chamber 2 into a loaded pallet chamber 2a and an empty pallet chamber 2b.

Furthermore, on both the left and right sides of the caster pallet chamber 2,
The chain belts 4 that touch the left and right sides of the caster pallet C are installed facing each other, and a new product box B is installed.
When the caster pallet C full of pallets is sent into the loading pallet chamber 2a, the chain belt 4 moves in contact with the caster pallet C.

When the chain belt 4 starts moving, the caster pallet C that has already been fed into the loading pallet chamber 2a is in contact with the chain belt 4, so if the loaded product boxes B are gone, the stop bar 3 and is sent into the empty pallet chamber 2b.

At the same time, the caster pallet C, which has already been fed into the empty pallet chamber 2b, is sent out of the empty pallet chamber 2b by the movement of the chain belt 4.

A movable frame 5 is placed on the upper part of the underframe 1 so as to be movable in the left-right direction in FIG.
A cylinder rod 7a attached to the front and rear frames 6 is attached to the front and rear frames 6.

Therefore, when the cylinder 7 operates, the front and rear frames 6 are pushed and pulled by the rods 7a and move from the loading pallet chamber 2a side to the empty pallet chamber 2b side, or vice versa.

On the front and rear frames 6, there is a rack rod 9 which is moved up and down by a motor 8, and at its tip there is a holding piece 10 that holds both left and right sides of the upper edge of the product box B with cylinders (not shown). and is provided. This holding piece 10
A photosensor 20 is attached to the center. When the rack lever 9 is lowered by the motor 8 and the holding piece 10 is lowered onto the product box B supplied by the caster pallet C, the photosensor 20 of the holding piece 10 detects the top product box B. Upon detection, the motor 8 is stopped, the rack rod 9 is positioned, and the holding pieces 10 are narrowed by the cylinder to hold the product box. Thereafter, the motor 8 rotates in the reverse direction and the rack lever 9 rises, lifting the product box B to the highest position.

The highest and lowest positions of the holding piece 10 and the positions of the mounting table 13 (to be described later) are detected by detecting the relative positions of the rack rod 9 and the front and rear frames 6 using a proximity switch or the like.

The moving frame 5 and the underframe 1 each have a cylinder 1.
1 and 12 are installed, and the rod 11
a and 12a are connected, and by operating the cylinder 11 and expanding and contracting the rod 11a, the holding piece 10 is positioned in either of the left and right rows of the product box B in FIG.

Further, as the cylinder 12 operates, the rod 12a expands and contracts, and the holding piece 1 is attached to the left row of the product box B in the figure and the installation stand 13 on which the product box B is placed.
Therefore, the product boxes B in either the left or right rows can be transferred to the position of the installation table 13, or vice versa, by the combined operation of the cylinders 11 and 12. In addition, the motor 8, the holding piece 10, the rack rod 9,
The cylinders 7, 11, 12, etc. constitute the moving means of the present invention.

In this way, the installation stand 13 on which the product box B is placed is equipped with several push rods 15 that push up the product A stored in the product box B by the operation of the cylinder 14. The push-up rod 15 has through hole B ₁
The product A in the product box B is pushed up above the top surface of the product box B. In addition, cylinder 1
4. The push-up lever 15 and the like constitute the push-up means of the present invention.

Furthermore, in order to avoid the push-up rod 15, it is made into a comb-like shape,
In addition, a receiving plate (receiving plate means) 16 having a protrusion 16a protruding from its upper surface can be moved laterally by a cylinder 17,
It is attached to the underframe 1.

Then, product A is pushed up into the push rod 15 as described above.
When the product A is pushed up by the cylinder 17,
The product A moves to the lower surface of the product A, and then the cylinder 14 operates in the opposite direction to lower the push rod 15.
is transferred onto the receiving plate 16.

The receiving plate 16 on which the product A has been transferred in this manner is moved to the belt conveyor D with the product A placed thereon by the operation of the cylinder 17 in the opposite direction.

Above the moving position of this receiving plate 16 is a cylinder 1.
Several support rods 19 are installed that move up and down by means of a cylinder 18, and when the receiving plate 16 carries the product A and moves to this position, the cylinder 18 operates and the support rods 19 move up and down.
Although it does not hit the receiving plate 16, it descends to a position lower than the protrusion 16a and suppresses the outer periphery of the product A.

Next, when the next product box B is placed on the installation stand 13 and the product A in the product box B is pushed up above the top surface of the product box B by the push rod 15, the receiving plate 16 is moved by the cylinder 17. Then, it is moved onto the installation stand 13 again. At this time, since the outer periphery of the product A is held down by the support rod 19, the product A does not move together with the receiving plate 16 and can be transferred onto the belt conveyor D. Incidentally, the cylinder 18, the support rod 19, etc. constitute the support means of the present invention.

Since the configuration of this embodiment is as described above, when the caster pallet C loaded with the product boxes B containing the products A is sent into the pallet loading chamber 2a, the pallet has already been sent to the pallet loading chamber 2a. has been entered,
As will be described later, the caster pallet C whose product box B has been emptied is sent to the empty pallet chamber 2b.

At the same time, a caster pallet C, which has been sent to the empty pallet chamber 2b and is loaded with empty product boxes as described later, is sent out from the empty pallet chamber 2b and is transferred to a caster pallet C loaded with product boxes B containing product A. Star pallet C and caster pallet C loaded with empty product boxes B can be exchanged.

The product box B containing the product A on the caster pallet C is held by the holding pieces 10 and carried directly above the installation stand 13 alternately on the left and right sides, and is lifted onto the installation stand 13 by the lowering of the rack rod 9. It will be placed. After the product box B has been placed, the holding piece 10 is opened by the cylinder, and the rack rod 9 is raised to remove the holding piece 1.
0 rises and retreats.

Next, the push-up rod 15 rises due to a push button or a signal due to a shortage of product A in the next process and lifts product A from product box B, and then the receiving plate 16 moves to position it on the bottom surface of product A. Then, the push rod 15 is lowered and the product A is transferred to the receiving plate 16.

Thereafter, the receiving plate 16 moves onto the belt conveyor D and is conveyed, and at the same time the holding piece 10 descends to grasp the empty product box B, moving the moving frame 5 and the front and rear frames 6.
By this movement, empty product boxes B are placed in alternating left and right rows on the caster pallets C of the empty pallet chamber 2b.

Then, the holding piece 10 carries the product box B containing the product to the mounting table 13, and the holding piece 10 rises and retreats.

On the other hand, the outer periphery of the product A transferred onto the receiving plate 16 and positioned on the conveyor is held down by the lowered support rod 19, and the receiving plate 16 moves downward to receive the next product A. Depending on the receiving plate 16
Product A, which has been transferred above, is transferred onto belt conveyor D.

Finally, the support rod 19 is raised and the belt conveyor D carries the product A to the desired location.

〔Effect of the invention〕

As described above, the present invention installs a product box at a predetermined location using a moving means, pushes up the product in the product box using a push-up means, and places the product on a receiving means using a receiving plate means. By operating each of these means with mechanical power, the products in the product box can be transferred to receiving means such as a conveyor or packaging machine without using human power.

Therefore, the work efficiency can be significantly improved by setting the program so that the operations of each means are performed in an orderly manner without tiring the operator unlike when the operation is performed manually.

In addition, since consumption costs and power costs are far lower than labor costs, work costs can be reduced and costs can be reduced.

The present invention can be used in a wide range of applications, such as a device for taking out products such as the above-mentioned record discs from product boxes, as well as devices for taking out products delivered from subcontractors from returnable boxes.
