Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a rotary transfer device for canning, bottling, etc. used in the manufacturing industry of food, drink, medicine, etc. The present invention relates to an apparatus capable of uniformly performing the various desired treatments described above by reliably rotating the canned goods, bottled goods, etc. while transporting them and sufficiently stirring the contents during heating, sterilization, cooling, and other treatments.

(Prior Art) Conventionally, in order to transfer articles and perform treatments such as steaming and cooling, a suspended conveyor chain is used to transport articles by suspending a conveyor chain in a meandering manner within a processing chamber.
It is known from the publication No. 56-37594.

In addition, as a device for rotating articles as desired during transportation, a bucket is attached to a pair of conveyor chains, and an aligning member is brought into contact with the lower surface of the cylindrical object in the bucket, and a rod-shaped object is used to rotate the cylindrical object. The bucket conveyor for transporting goods was developed in 1989-9006.
It is known from the specification (Utility Model Application Publication No. 51-91493).

(Problem to be solved by the invention) The conventional hanging transfer device described above has a hanging member to which a flat board is attached and is supported by a pair of left and right chains, so it is relatively stable for kamaboko, etc. Although it is possible to fully demonstrate its suspension ability by placing items on it and transporting them in a meandering manner within the processing chamber, it is difficult to place items that are cylindrical and easily rotated, such as canned goods or bottles. When the items are transported in a meandering manner through the processing chamber, the items placed there may fall off the hanging transfer device, which not only prevents the desired processing, but also damages the items or produces defective items. In addition, since it is not equipped with a rotating transfer device for items, it is necessary to ensure rotation while transferring canned goods, bottled items, etc. during heating, sterilization, cooling, and other processing of canned goods, bottled items, etc. The effect of sufficiently stirring the contents and uniformly carrying out the various desired treatments described above is not achieved.

In addition, in the bucket conveyor for transporting stick-like objects described above, since the bucket for storing the objects is attached to the conveyor, accidents such as falling due to rotation of the objects during transportation are prevented by this bucket. , On the other hand, since the alignment member that contacts the lower surface of the cylindrical object is configured to abut on both ends of the cylindrical object, that is, the part protruding from the bucket,
In various processes such as canning and bottling where both ends have different diameters (especially bottle shapes as shown in Fig. 1), the alignment members disposed on the left and right sides do not contact uniformly, and the contact state The so-called short objects, which are unstable and cannot generate rotational movement by transporting the bucket, and cannot protrude from both ends of the basket, may not engage or come into contact with the alignment member. Since this is not carried out, a sufficient stirring effect of the contents of the cylindrical object cannot be obtained, resulting in the occurrence of defective products.

It had various problems such as.

The present invention was developed to solve the above-mentioned problems, and during heating, sterilization, cooling, and other processing of canned goods, bottled goods, etc., the canned goods, bottled goods, etc. are reliably rotated while being transferred. It is an object of the present invention to provide a rotary transfer device capable of sufficiently stirring the contents and uniformly carrying out the various desired treatments described above.

(Means for Solving the Problems) The means of the present invention for achieving the above-mentioned object consists of a pair of wires that are suspended upwardly or downwardly in a meandering and endless manner within the processing chamber, and are spaced apart at a predetermined distance. In a processing device that performs predetermined processing by transporting the material by a conveyor chain, the material is sandwiched between the pair of conveyor chains and suspended in a constant posture by a shaft attached to the conveyor chain, and a cylindrical material to be processed is pushed through walls at the front and rear. a notch provided at the bottom of the basket along the entire length in the direction of travel; and a notch provided parallel to the conveyor chain and corresponding to the passing position of the notch, the notch entering into the bottom of the basket through the notch, and a cylindrical A rotation inducing member that stably supports the cylindrical object on the lower surface of the circumferential body of the cylindrical object and rotates the cylindrical object as the basket moves. The structure of the rotary transfer device is as follows.

(Function) With the configuration described above, the present invention exhibits the following functions.

When a basket is attached by its attachment shaft to a conveyor chain suspended endlessly in a meandering manner above or below the processing chamber, the basket is suspended in a fixed posture, that is, horizontally.

When the conveyor chain is driven and cylindrical objects such as canned goods and bottles are accommodated in the basket so as to be rotatable in the moving direction, the objects to be processed hit the pushing wall of the basket as the basket advances. When the basket moves inside the processing chamber while being pushed by this wall, a rotation inducing member provided on the lower side of the conveyor chain corresponding to the notch position of the basket enters the notch in the basket and causes the rotation of the object to be processed. It comes into contact with the lower surface of the circumferential body, that is, the position where the workpiece is stably supported, and lifts the workpiece to a height where it can rotate.

Then, the object to be processed rotates in the opposite direction to the direction of movement due to friction with the rotation inducing member, and while rotating in the basket, it is further pushed by the pushing wall and meandering upward or downward within the processing chamber. move while

At this time, for example, even heat exchange with a medium for heating, cooling, etc. is performed by rotation, and treatments such as heating, sterilization, cooling, etc. are efficiently performed.

(Example) Next, an example of a rotary transfer device for canned food, bottled food, etc. related to the present invention will be described based on the drawings.

In Fig. 6, A is a processing device that performs processing such as heating, sterilization, and cooling of cylindrical processing objects b such as canned goods and bottles, and has a rectangular processing chamber 1 formed at a predetermined height. 1 has a closed structure to prevent heat radiation when sterilizing, heating, etc., and has an open structure to allow heat radiation when cooling.

In the processing chamber 1, a large number of sprockets 2 are supported at predetermined intervals with the horizontal center shifted up and down, and the sprockets 2 are arranged in a meandering manner.
A pair of conveyor chains 3, 3 are suspended in an endless manner, and the driving means 4 causes these conveyor chains 3, 3 to move from the bottom to the top and to perform a circular movement from the top to the bottom. Thus, a moving distance over which a predetermined process is performed is formed.

Reference numeral 5 designates a basket which is attached to the conveyor chain 3 and stores the workpiece b, and is composed of both side plates a, a, pushing walls c, c, and a bottom part d.
~ As shown in Figure 2, the partition wall e is formed to a length that is sandwiched between the pair of conveyor chains 3, 3.
The objects to be processed b are accommodated one by one in the respective accommodation chambers divided by.

The mounting shafts 6, 6 protruding outward from the side plates a, a are rotatably attached to the conveyor chains 3, 3, and the conveyor chains 3, 3 are suspended in a meandering manner into the processing chamber 1. Even if it tilts or moves by diffraction, it is suspended in a constant position so that the bottom d always remains in a horizontal state with the bottom d pointing downward.

Moreover, the basket 5 has pushing walls c, c and a bottom part d.
It has a porous structure such as a net or perforated plate to allow ventilation and water to flow freely.

Reference numeral 7 denotes a notch provided at the bottom d of the basket 5 to allow a rotation inducing member (to be described later) to enter the basket 5. As shown in FIGS. Either two strips are provided at intervals, or one wide strip is provided in the center, although it is not shown in the drawing. It is preferable to drill the object b at a position where it is stably supported by the rotation inducing member.

Reference numeral 8 denotes a rotation inducing member for the cylindrical workpiece b, which is provided corresponding to the passage position of the notch 7, and enters into the bottom of the basket 5 from the notch 7 to cause the cylindrical object b to be accommodated in the basket 5 to be rotated. By lifting the shaped object b from the bottom d, rotation of the object b is induced as the basket 5 moves.

As shown in FIG. 3, the structure includes a fixing rod that is attached to the processing chamber 1 by an attachment member 10 and has a friction piece 11 made of rubber, plastic, etc. attached to the contact part with the lower surface of the object to be processed b. Alternatively, as shown in FIG. 4, a belt suspended from a belt pulley 12 supported in the processing chamber 1 with its surface in contact with the lower surface of the workpiece b may be used, or as shown in FIG. In this way, a reciprocating rod equipped with friction pieces 11 supported by a sliding metal 13 and reciprocated by a crank (pinion rack or cylinder) 14 is used to cause friction between these pieces and the workpiece b in the basket 5. The object b to be processed rotates as it advances.

Reference numeral 15 denotes a printing protection member attached to a portion of the basket 5 that is hit by the object to be processed b, and is made of a material that does not damage the printed film such as plastic on the surface of the object to be processed and has as little frictional resistance as possible.

It should be noted that the basket 5 described above can reliably rotate and transport any object b that can fit therein, regardless of its size.

(Effects of the Invention) The rotary transfer device of the present invention configured as described above is provided with a rotation inducing member that stably supports the cylindrical workpiece on the lower surface of the circumferential trunk of the cylindrical workpiece. Heating, sterilizing, cooling canned and bottled food, etc.
In other treatments, the canned goods, bottles, etc. can be reliably rotated while being transferred to sufficiently agitate the contents, thereby making it possible to uniformly perform the various desired treatments described above.

In particular, this rotation-inducing member is arranged so as to come into contact with the circumferential body of the object to be processed, where there is almost no difference in the diameter of the body. Even during processing, it reliably induces rotation, and internal stirring causes
Processes such as heating, sterilization, cooling, etc. can be performed efficiently by performing even heat exchange with a medium for heating, cooling, etc.

In addition, the conveyor chain with the basket attached is suspended in a meandering and endless manner above or below the processing chamber, making it possible to obtain the necessary distance for processing even in a narrow factory space. Effective use of space can be measured.

The baskets containing the objects to be processed are pivoted to the conveyor chain so that they are in a horizontal position, so that they are always suspended in a constant position even when they are conveyed in a meandering, inclined or diffracted manner.

The objects to be processed are caused to rotate as the conveyor chain moves by a rotation inducing member in contact with the lower surface of the objects, so that the objects to be processed are uniformly processed, and the objects are transferred by the pushing walls at the front and rear of the basket. It can be carried out with both the outward and return directions in contact, and even with inclined or diffraction transfer,
The pushing wall prevents the objects to be processed from rolling and there is no damage to the objects, so there are no defective objects to be processed during processing.

It has special effects such as
