Description

  TECHNICAL FIELD The present invention relates to a beverage container punching device that opens a hole in a beverage container such as a plastic bottle or a can and discharges or drains a leftover beverage from the beverage container.

  After drinking, beverage containers such as empty plastic bottles and cans are collected and transported to a recycling facility for recycling. In the process of recycling such beverage containers, the target beverage container is to be traded based on the weight, so it is necessary to measure the weight of the empty beverage container. Beverages may remain, and the weight of the beverage container itself cannot be determined even if the weight of the collected beverage container is measured as it is.

  Therefore, for example, a crushing device for a plastic bottle as described in Patent Document 1 is known. This crushing device for PET bottles is provided with a pair of cutting crushing rollers, the cutting crushing roller includes a drive shaft, and a plurality of cutting blades with protruding blade portions provided on the drive shaft, It is comprised so that a PET bottle may be wound between cutting blades, and a hole may be made in the wound PET bottle with a protruding blade portion.

JP 2004-122142 A

  By the way, for example, since a PET bottle has high strength and ductility, even if the PET bottle is caught between a pair of cut crushing rollers, it is not always possible to make a hole in the PET bottle. Although it is necessary to increase the number of cutting blades in order to make a hole in a PET bottle reliably, when the number of cutting blades is increased, the load applied to the apparatus becomes too large. Alternatively, it is possible to increase the overlapping length of the protruding blades on both sides, but this time there is a risk of destroying the plastic bottle, which may hinder the subsequent recycling process, and the load applied to the device May become too large.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a beverage container punching device that can easily and reliably form a hole in a beverage container that can sufficiently drain residual beverage without destroying the beverage container.

  To achieve this object, the beverage container drilling device of the present invention forms a drilling area or a container passage between the first drilling rotary drum and the first drilling rotary drum. A second perforated rotating drum disposed on the first perforated rotating drum and the second perforated rotating drum to each other for guiding a beverage container to the perforating area or the container passage. A beverage container punching device configured to rotate in the opposite direction, wherein the first drilling rotary drum includes a first drum body and an outer periphery of the first drum body in a circumferential direction. A first row of drilling blades formed by arranging a plurality of first drilling blades at intervals, and the first row of drilling blades is a shaft of the first drum body. A plurality of second perforated rotary drums are formed at intervals in the direction. And a second row of drilling blades formed by arranging a plurality of second drilling blades at intervals in the circumferential direction on the outer periphery of the second drum body. A plurality of rows of the perforating blades are formed at intervals in the axial direction of the second drum body, and the first perforated blade row and the second perforated blade row are arranged in the axial direction. The cutting edge circles of the first drilling blade row and the cutting edge circles of the second drilling blade row overlap each other at least at the center of the drilling area or the container passage, The rows of the first drilling blades adjacent in the direction are provided so that the circumferential positions of the first drilling blades are shifted (provided so that the phase in the circumferential direction is shifted), and are adjacent in the axial direction. The row of the second perforating blades to be fitted is provided so that the circumferential position of the second perforating blades is shifted (the circumferential position). Provided such shifts are) those. For example, the cutting edge circle of the first drilling blade row and the bottom circle of the second drilling blade row do not overlap, but the cutting edge circle of the second drilling blade row and the first drilling blade It is configured not to overlap with the bottom circle of the row.

Is provided. Accordingly, in the first row of drilling blades adjacent in the axial direction, the first drilling blade passes, for example, the center of the drilling region while shifting the time, so that a number of first drilling blade rows are provided. However, an excessive load does not act on the beverage container punching device. Similarly, also in the row | line | column of the 2nd drilling blade adjacent in an axial direction, a 2nd drilling blade passes the center of a drilling area, for example, shifting time. Therefore, even if many rows of second punching blades are provided, an excessive load does not act on the beverage container punching device. If a large number of first drilling blade rows and second drilling blade rows are formed, the overlap length between the first drilling blade row and the second drilling blade row is increased. Even if it is not, it is possible to make a necessary hole in the beverage container.

  The beverage container drilling device of the present invention also includes a first drilling rotator and a second drilling rotator arranged to form a drilling area between the first drilling rotator and the first drilling rotator. A beverage container configured to rotate in opposite directions with respect to each other in order to guide the beverage container to the piercing area.
