Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bottle picking apparatus for a bottle case and a bottle case / cardboard box transfer machine using the same. At present, factories and distribution centers handle a plurality of bottles, a plurality of cans, and articles in bottle cases and cardboard boxes to efficiently transport beverage bottles and various articles. Usually, several to several tens of food bottles and the like are stored in the bottle case, and several to several tens of various articles are similarly stored in the cardboard box. If one or two bottle cases or cardboard boxes are handled at a time, it can be handled by human power or a simple handling device without taking a special method. Conversely, when handling a large amount at the same time, a method in which a bottle case or a cardboard box is accommodated in an arbitrary container and transported, or a method of continuously transporting the container by a conveyor or the like is suitable.

[0002] An intermediate amount between these, for example, four bottle cases
When handling about 10 to 10 pieces at the same time, or handling about the same number of cardboard boxes, handling is extremely inconvenient with a simple handling device,
However, a conveyor suitable for mass distribution is inefficient. Therefore, layer picking is performed in which several to several tens of cardboard boxes are aligned on the same plane, and they are collectively picked at a time. Use of this layer picking method is convenient for wholesale to small customers. This is because, for example, a shipping mode can be adopted in which a bottle case of a beer bottle is stacked in a fraction box, a cardboard box of a juice can is stacked in a fraction box, and a cardboard box of a tea beverage can is stacked in a fraction box. The present invention relates to a picking device that picks up such a plurality of packages in units of layers, and a transfer machine that uses the device to reload several types of packages in units of layers and sorts the quantity of articles required by a customer.

[0003]

2. Description of the Related Art In a place where a layer picking device is used, conveyed cardboard boxes and bottle cases are arranged in a plurality of rows and a plurality of rows, and the cardboard box groups and bottle case groups are vertically stacked. . A layer picking device is used for picking the uppermost cardboard box group and bottle case group from among them. Conventional layer picking devices used for such applications include the following. First
Uses a vacuum device. With this device, when trying to pick only the upper layer of cardboard boxes stacked on top and bottom, the adhesive that temporarily bonded the upper cardboard box and the lower cardboard box must be peeled to prevent load collapse, Even if a suction force is applied in the direction perpendicular to the adhesive surface, it is difficult to peel it off, and even if the gaps and joints between adjacent cardboard boxes are vacuumed, sufficient lifting force cannot be obtained. Not suitable for picking. Further, since the bottle case has no flat suction surface in the first place, suction lifting is impossible. Second,
It uses a clamp device. In this apparatus, a cardboard box group arranged in two rows and two rows can be conveyed by clamping from the outside, but a cardboard box group arranged in three columns and three or more rows can be clamped to the outer cardboard box. However, since the inner cardboard box cannot be clamped directly, there is a risk of dropping during transportation. The only way to prevent the inner cardboard box from falling is to increase the clamping force, but this would cause the outer cardboard box to collapse. Although the bottle case is easier to clamp than a cardboard box, the bottle case is still heavy and the bottle case sandwiched inside can fall. Third, a roller conveyor equipped with a pickup roller is used. In this device,
For stratification of the cardboard box group stacked up and down,
Since the adhesive layer between the upper and lower layers can be peeled off from the end in order, the efficiency is good, and since it is supported by the rollers from the lower surface, the inner cardboard box does not drop, and it is said that it is currently most suitable for picking a group of cardboard boxes. However, in the case of a bottle case, since the outer periphery has an edge portion, the pickup roll is easily damaged by abrasion at the edge portion and cannot be used.

[0004] A layer picking device is incorporated, the bottle cases and cardboard boxes before sorting are picked as specified, and the number of bottles and cardboard boxes according to the number of products and sorts required by the sorting destination are stacked. There is a technique described in Japanese Patent Application Laid-Open No. H8-277036 as a transfer machine that sorts pieces by the number of cases or boxes of about 10 to about 10 pieces. This conventional example will be described with reference to FIG. The basic structure is such that a layer picking device 110 and a dispensing device 140 are provided at an interval, and a traveling vehicle 130 is arranged between them. The layer picking device 110 is used exclusively for cardboard boxes,
Is of the third type having a pickup roller 115. If there is one cardboard box X0 to be paid out at the rear end of the traveling vehicle 130, the traveling vehicle 13
0 travels toward the layer picking device 110, and the pickup roller 115 enters the lower part of the uppermost cardboard box X1. When the pickup roller 115 enters the innermost part of the pickup area, the traveling vehicle 130 exits from the dispensing device 140, and the cardboard box X0 on the traveling vehicle 130 is discharged to the lifter 142. Lifter 142
Moves the cardboard box X0 onto the conveyor 141.
Thus, the pick-up operation and the payout operation are performed in parallel. Also, on the layer picking device 110 side, the uppermost cardboard box X1 is transferred onto the moving belt 132 of the traveling vehicle 130, so that the traveling belt 132 is simultaneously moved toward the dispensing device 140 and the transport belt 132 is moved to the dispensing device 140 side. When the cart is rotated in the same direction and at the same speed, the cardboard box X1 on the transfer belt 132 can reach the dispensing device 140 when the rear end of the traveling carriage 130 reaches the inside of the dispensing device 140. it can. In this way, the traveling of the traveling carriage 130 and the rotation of the transfer belt 132 are performed in parallel, so that the next cardboard box X1 can be transferred to the lifter 142. In this way, the cardboard boxes X1 and X2 of a plurality of layers can be sequentially reloaded on the conveyor 141 and sorted.

However, in the conventional transfer machine, since the layer picking device 110 is of a type using a pickup roll, it can handle only cardboard boxes and cannot transfer bottle cases. However, since picking and transshipping in layers are highly efficient, it is desired that bottle cases can be similarly picked and transshipped in layers. In particular, since the bottle case is heavy and manual work is difficult, there is a strong demand for mechanization. However, if the conventional example of FIG. 13 is used, the layer picking device 110 and the traveling cart 131 are removed every time the picking of the cardboard box is changed to the picking of the bottle case, and a clamp-type layer picking device or pickup suitable for the bottle case. It must be converted to a traveling carriage 131 without the rollers 115. Such an operation is very inconvenient and time consuming.

[0006]
