Description

  The present invention relates to a cleaning device for cleaning a pallet.

Pallets are used to carry items such as beverage products (eg, packaged beer products). Such a pallet is often contaminated by dust, dirt, snow, etc., and when an article is placed on the dirty pallet, the article becomes dirty. Furthermore, if an article is placed on a pallet with a broken bottle or the like placed on the pallet, the article may be damaged or damaged.
Patent Document 1 discloses a cleaning device in which a brush member is disposed above a movement path of a pallet, and when the pallet moves, the brush member is slidably contacted with the upper surface of the pallet to remove foreign matter.
JP-A-8-175644

In the cleaning apparatus described in Patent Document 1, foreign matter on the top surface of the pallet is swept away by a brush member from one end of the pallet toward the other end, and foreign matter is removed from the other end. Therefore, when the brush member finishes sweeping the top surface of the pallet, the foreign matter on the entire surface of the pallet is swept up by the brush member. However, when a large amount of foreign matter is swept up by the brush member, a part of it passes through between the brush member and the top surface of the pallet, and uncleaned parts may be generated. In particular, when the snow on the pallet is swept away, the snow swept by the brush member is pressed against the upper surface of the pallet by the brush member and hardens, and this may remain on the pallet.
The present invention has been made on the basis of recognition of the problems as described above, and an object of the present invention is to reduce uncleaned cleaning or poor cleaning.

The present invention relates to a cleaning device that cleans a pallet, and the cleaning device rotates a conveyor that conveys a pallet while contacting a top surface of the pallet on the conveyor, the conveyor, and the cylindrical brush. A cylindrical driving body having a suction hole, a rotary joint for connecting the supporting body to a suction device, and removal on the pallet by rotation. A first brush member having a first spiral groove formed so as to extrude the object to the first side of the conveyor, and a second object to extrude the object to be removed on the pallet by rotation to the second side of the conveyor. A second brush member formed with a spiral groove, wherein the first brush member is disposed on the first lateral side around the support, and the second brush member is around the support. Disposed definitive the second lateral side, removing objects the suction holes on the pallet, characterized in that it is sucked by the suction device through the support and the rotary joint.

  According to the present invention, it is possible to reduce uncleaned cleaning or poor cleaning with a brush.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a side view showing a schematic configuration of a pallet cleaning apparatus according to a preferred embodiment of the present invention. FIG. 2 is a plan view showing the relationship between the spiral groove of the cylindrical brush and the rotation direction of the cylindrical brush in the pallet cleaning apparatus 100 shown in FIG.

A pallet cleaning apparatus 100 shown in FIG. 1 is configured to clean the upper surface of the pallet 1 by brushing. The pallet 1 can be used to transport various articles, such as beverage products (eg, packaged beer products). Articles to be conveyed can be arranged on the pallet 1 in an aligned state.
The pallet cleaning device 100 includes a conveyor 10 that conveys the pallet 1 in the horizontal direction and a cylindrical brush 20 that rotates while contacting the upper surface of the pallet 1 on the conveyor 10. The pallet cleaning apparatus 100 can include, for example, a pallet magazine 50 that accommodates a plurality of pallets 1 and provides them one by one on the conveyor 10.
The conveyor 10 can be configured as a chain conveyor or a belt conveyor, for example. For example, the chain or belt of the conveyor 10 is stretched around the driving wheel 32 and the driven wheel 34, and can be driven by the driving wheel 32. The cylindrical brush 20 is preferably driven by a drive source that drives the drive wheels 32. Thus, by driving the conveyor 10 and the cylindrical brush 20 by a single drive source, the ratio between the conveying speed of the pallet 1 by the conveyor 10 and the rotational speed of the cylindrical brush 20 can be easily made constant. . For example, when the conveyance speed of the pallet 1 by the conveyor 10 is increased in order to increase the throughput, the rotational speed of the cylindrical brush 20 is increased accordingly, and cleaning failure due to the increase in the conveyance speed is prevented.

In the embodiment shown in FIG. 1, a transmission wheel (for example, a sprocket) 36 is connected to the drive wheel 32, and the transmission wheel 38 and the transmission wheel 40 connected thereto, the transmission wheel 22 connected to the cylindrical brush 22, In addition, the cylindrical brush 20 can be driven via the transmission chains 42 and 44. That is, in the embodiment shown in FIG. 1, the driving force provided to the driving wheel 32 by a driving source (not shown) is also transmitted to the cylindrical brush 20 by the driving force transmission mechanism constituted by the transmission components 36 to 44. The
As illustrated in FIG. 2, the cylindrical brush 20 is first rotated so as to push an object to be removed (for example, dust, dust, snow, etc.) on the pallet 1 to the first side A of the conveyor 10 by rotation. The first portion 24 in which the spiral groove 24a is formed and the second portion 26 in which the second spiral groove 26a is formed so as to push the object to be removed on the pallet 1 to the second side B of the conveyor 10 by rotation. Including. The first portion 24 is disposed on the first side A side, and the second portion 26 is disposed on the second side B side. Here, the spiral direction of the first spiral groove 24a and the second spiral groove 26a is opposite.
As the first portion 24 rotates, the object to be removed on the pallet 1 is pushed out to the first side A along the first spiral groove 24a, while on the pallet 1 as the second portion 26 rotates. The removal target is pushed out to the second side B along the second spiral groove 26a. Here, when the rotation direction of the cylindrical brush 20 is reversed, the rotation directions of the spirals of the first spiral groove 24a and the second spiral groove 26a are reversed.

According to the cylindrical brush 20 of this embodiment, the object to be removed on the pallet 1 is swept out to both sides (one end side of the cylindrical brush 20 and the opposite side) with the rotation thereof. When the pallet 1 is brushed by the above, a large amount of removal object does not accumulate on the cylindrical brush 20, and uncleaned or poor cleaning is reduced.
FIG. 3 is a diagram illustrating a configuration example of the cylindrical brush 20. The cylindrical brush 20 is a means for sucking an object to be removed on the pallet 1, more specifically, an object to be removed attached to the brush members 24b and 26b of the cylindrical brush 20 or accumulated in the spiral grooves 24a and 26a. It is preferable to provide. In the configuration example shown in FIG. 3, brush members 24b and 26b are disposed around a cylindrical support 28 having a suction hole 28a as a suction portion. The support body 28 is connected to a suction device (not shown) via a rotary joint.

It is a side view which shows schematic structure of the pallet cleaning apparatus of suitable embodiment of this invention. It is a top view which shows the relationship between the spiral groove of the cylindrical brush in the pallet cleaning apparatus shown in FIG. 1, and the rotation direction of this cylindrical brush. It is a figure which shows the structural example of a cylindrical brush.
