Description

  The present invention relates to an empty can compression processor for compressing empty cans and collecting the compressed ones.

  The empty can compression processing machine for compressing cylindrical empty cans such as various soft drinks and beer compresses the empty cans in the radial direction (direction perpendicular to the length direction) and in the length direction. It is roughly divided into those based on the method. Here, the former requires less force to compress the empty can than the latter, but since the empty can cannot be compressed into a compact form, there is a disadvantage that the compressed one is bulky compared to the latter.

  As an empty can compression processing system that compresses empty cans in the length direction, a can storage container is installed on the base plate, and the pressure plate placed so that it can reciprocate up and down is pushed down by lever operation to store the can There has been proposed one that compresses an empty can placed in the container. (For example, refer to Patent Document 1).

JP 2005-131670 A

  In order to compress an empty can with the empty can compression processor having the above-described configuration, first, the empty can is put into a can storage container. Here, in order to compress the empty can straight in the length direction, it is necessary to prevent the empty can from tilting during the compression process, and for this purpose, positioning is performed so that the center of the empty can is correctly pushed inside the can storage container. There is a need to do.

However, it is not easy to position the empty can by aligning the center of the empty can with the center of the inside of the can storage container, and in order to properly compress various empty cans having different diameters, the can can be stored according to the diameter of the empty can. It is necessary to replace the container, and the efficiency of the work is deteriorated.
Moreover, in the above-mentioned empty can compression processing machine, the operation | work which takes out and collect | recovers the compressed empty cans from a can storage container is required, and collection | recovery work is troublesome.

  This invention was made paying attention to the above-mentioned problem, and aims to provide an empty can compression processing machine capable of compressing an empty can straight in the length direction regardless of the diameter of the empty can. To do.

  An empty can compression processing machine according to the present invention has a bottomed case body having an empty can inlet opening on the upper surface and an empty can housing chamber below the inlet, a stand that supports the case body, and the case body And a compression mechanism for compressing and deforming the empty can introduced into the empty can storage chamber from the inlet. The case body includes a front wall and a rear wall that face each other, both side walls that face each other, and a bottom plate that slopes lower toward the center of the width at the same tilt angle than the lower ends of the side walls. In the vicinity of the front wall of the bottom plate, there is provided a dropping port for dropping an empty can after the compression treatment, and a long protruding wall portion is formed in the center of the width of the front wall. The compression mechanism includes a pressure plate disposed in the empty can housing chamber so as to be capable of reciprocating in the front-rear direction, a driving member that supports and reciprocates the pressure plate, an input shaft that inputs rotational driving force, and the input And a transmission mechanism that converts the rotation of the shaft into a reciprocating linear motion and transmits it to the drive member.

  In order to compress an empty can with the empty can compression processor of the present invention, first, an empty can is placed in an empty can housing chamber of the case body so that an end surface thereof is in contact with a protruding wall portion formed on the front wall of the case body. Since the bottom plate of the case body is inclined from the lower end of both side walls to the center of the width at the same inclination angle, the empty can can be positioned at the center of the width inside the case body regardless of the diameter.

  When the input shaft is rotated in a predetermined direction for pressurizing the empty can (hereinafter referred to as the “pressing direction”), the rotational driving force of the input shaft is converted into a linear motion by the transmission mechanism and transmitted to the driving member. The pressure plate moves toward the front wall while being pushed by the driving member and maintaining a vertical posture. When the empty can is pressurized by the pressure plate, the protruding wall portion bites into the end surface of the empty can, thereby preventing the horizontal can from being displaced in the lateral direction. Further, since the empty cans are supported on the inclined surfaces of the left and right bottom plates, the floating can be suppressed and the empty cans are compressed straight along with the movement of the pressure plate. After the empty can compression process is completed, the input shaft is rotated in the direction opposite to the pressing direction (hereinafter referred to as “anti-pressing direction”), and the pressure plate is moved toward the rear wall. Is released from the applied pressure and falls from a drop opening provided in the bottom plate. Note that the input shaft can be rotated manually or by using a driving device such as a motor.

  In a preferred embodiment, the protruding wall portion is provided between the upper end and the lower end of the front wall. According to this embodiment, when the empty can is released from the pressurizing force, the protruding wall portion falls along the protruding wall portion without being caught by the end face of the empty can and becoming an obstacle to dropping.

  Also, in a preferred embodiment of the present invention, the drive member includes a rack whose one end is connected to a position above the inclined lower end of the bottom plate on the diameter line of the disk-shaped pressure plate, and an upper and lower side sandwiching the rack. It consists of two metal rods connected at one end to the position. The rack and the metal rods are parallel to each other, project from the rear wall of the case body to the outside, and are integrally connected, and the transmission mechanism is configured by meshing a pinion with the rack.

  According to this embodiment, when the input shaft is rotated in the pressing direction, the rack moves linearly by the rotation of the pinion, whereby the pressure plate moves toward the front wall and crushes the empty can. In this case, since the two metal rods are connected in parallel to the vertical position across the rack on the diameter line of the pressure plate, the pressure plate can be pushed along the diameter line, resulting in an uneven load. This prevents the empty can from being compressed stably. Furthermore, the end surface of the empty can can be surely recessed by applying a strong pressing force between the protruding wall portion and the end surface of the empty can during compression by the pressure plate.

  In a further preferred embodiment of the present invention, hooks are provided on the outer surfaces of both side walls of the case body for hooking the handbag portion of the collection bag and suspending the collection bag.

  According to this embodiment, when the pressure applied to the empty can is loosened after the compression process of the empty can is completed, the compressed and deformed can falls from the dropping port and is recovered in the recovery bag suspended from the hook. Empty cans can be collected without getting your hands dirty.

According to the present invention, the empty can is supported in the center of the width of the empty can housing chamber of the case body, and the protruding wall portion provided on the front wall of the case body is pressurized while being bitten into the end face of the empty can. Regardless of the diameter, the empty can can be compressed and deformed straight in the length direction.
Furthermore, since the compressed empty can is dropped from the dropping port, an empty can can be recovered without contaminating the operator's hand by installing a recovery bag or a recovery box below the can, and the recovery operation is easy.

The projecting wall portion 36 of this embodiment is formed by spot welding a rectangular metal plate having a length corresponding to the distance between the upper and lower ends of the front wall 31 to the inner surface of the front wall 31. However, the present invention is not limited thereto, and the protruding wall portion 36 may be formed by performing sheet metal processing on the central portion of the width of the front wall 31. The projecting wall portion 36 has the same width over the entire length, and the central portion of the width is a pointed portion 36a.

  The compression mechanism 4 includes a pressure plate 5 disposed in the empty can housing chamber 35 so as to be movable in the front-rear direction, a drive member 6 that supports the pressure plate 5 in a vertical posture and reciprocates, and a rotational driving force. Input shaft 7 and a transmission mechanism 8 for converting the rotational driving force input to input shaft 7 into a reciprocating linear motion and transmitting it to drive member 6. In this embodiment, the drive member 6 includes a rack 60 and two metal rods 61 and 61, and the rack 60 constitutes a transmission mechanism 8 together with a pinion 80.

  The pressure plate 5 is made of a metal disk having a diameter larger than the diameter of the largest can that is to be compressed and has a sufficient thickness. One end of each of the two metal rods 61 and 61 is connected. As shown in FIG. 5, each metal bar 61 is connected to the upper and lower positions on the diameter line d of the pressure plate 5 with the rack 60 interposed therebetween. In the figure, P is the center of the pressure plate 5, the rack 60 is connected to a position near the center P, and the two metal rods 61, 61 are equidistant from the center P and connected to a position near the outer peripheral edge. Has been

The holes 39 are pivotally supported so as to freely reciprocate in the front-rear direction. The rack 60 and the metal rods 61 protrude to the outside of the case body 3, and the other ends of the rack 60 and the metal bars 61 are fixed to the connecting plate 62 by set screws 63 and 64.

  As shown in FIG. 6, the input shaft 7 has a hexagonal column shape, and a driving shaft 72 integral with the input shaft 7 is a protruding plate of a pair of left and right mounting plates 70, 70 attached to the rear wall 32 of the case body 3. The parts 71 and 71 are rotatably supported. An insertion hole 73 for passing the metal rod 100 is formed at the base end portion of the input shaft 7, and the input shaft 7 can be rotationally driven by rotating the metal rod 100. A ratchet handle 9 can be attached to the base end portion of the input shaft 7, and the input shaft 7 can be driven to rotate by rotating the ratchet handle 9.

  Although the ratchet handle 9 has a known configuration and will not be described in detail, the rotation of the handle 90 is transmitted to the socket portion 92 via the reversible ratchet mechanism 91. The socket portion 92 is fixed to the input shaft 7 by a set screw 93, and the input shaft 7 is rotationally driven integrally with the rotation of the socket portion 92.
