Description

  The present invention relates to a lubricant for bottle conveyors, and relates to a lubricant for bottle conveyors suitable for transporting bottles without using a liquid lubricant.

  Generally, in a beverage filling process in a production factory for milk, beer, liquor, soft drinks, etc., a bottle conveyor is used to convey bottles (hereinafter referred to as “bottles”) made of glass bottles, cans, resin bottles, and the like. ing.

  Such a bottle conveyor, for example, conveys bottles placed on a horizontal plate by chaining a plurality of small horizontal plates in a chain so as to pass a predetermined path and being driven by a drive source. . In the bottle conveyor formed in this way, the bottle is properly placed on the moving horizontal plate without falling down, and the bottle conveyor moves without falling down even when the bottle flow is stagnant. A moderately low coefficient of friction is required to continue the process.

In order to satisfy the requirements for the coefficient of friction, conventionally, a liquid lubricant in a state in which a desired lubricant is diluted in water is applied to the bottle mounting surface of a bottle conveyor, for example, the upper surface of a horizontal plate while dripping down. Was.
However, it is difficult to stably obtain a desired coefficient of friction even when a liquid lubricant is used, a bottle overturning phenomenon has occurred, and depending on the type of lubricant, the bottle can be transported on the surface of the bottle conveyor. A large amount of foam may be generated. Also, if the bottle is a resin bottle, the inside of the bottle is pressurized with carbon dioxide gas and stress is applied, so there is a risk of causing stress cracks on the bottle when the lubricant touches it. There is a risk that the beverage liquid filled in the bottle leaks.

  Therefore, it has been proposed to use a lubricant composition containing an inhibitor that suppresses the occurrence of stress-induced cracks (see, for example, Patent Document 1).

  However, in the conventional method, since the liquid lubricant is used, the bottle falls or bubbles are attached to the bottle, and the bubbles are detected as dirt. In order to use it, a system and equipment for performing waterproofing treatment and purification treatment are required, and there is a problem that the bottle may be damaged.

  The present invention has been made in view of these points, and can smoothly transport a bottle without using a liquid lubricant, and improve the lubricity and stability of the bottle placement surface of the bottle conveyor. In addition, it is possible to prevent bubbles from adhering to the bottles, prevent malfunctions of various inspection machines, reduce the load on the septic tank by not using liquid materials, eliminate the leakage of lubricants, and be environmentally friendly It is an object of the present invention to provide a lubricant for a bottle conveyor that can reduce the size of the entire apparatus and eliminate bottle breakage by eliminating the need for systems and equipment that have been conventionally required.

  The inventor has intensively studied and tried to obtain a resin bottle conveyor that does not require a liquid lubricant by using a fluororesin or the like on the bottle mounting surface of the bottle conveyor. Specifically, it was assumed that a horizontal plate was formed by applying a fluororesin or the like to the mounting surface or kneading directly into the resin. However, even if a fluororesin or the like is simply used, it is necessary to use water as a lubricant although a conventional lubricant is not required.

  Therefore, the present inventor has developed a lubricant containing a fluoroalkyl ether and a fluororesin inorganic binder, preferably 80 to 95% by weight of fluoroalkyl ether and 5 to 20% by weight of a fluororesin inorganic binder. By applying a lubricant containing the agent to at least the bottle mounting surface of the bottle conveyor and drying it to form a dry film, the bottle can be smoothly conveyed without using a liquid lubricant, The present invention was completed by discovering that the lubricity and stability of the bottle mounting surface of the bottle conveyor can be improved.

  Therefore, the lubricant for bottle conveyors of the present invention contains a fluoroalkyl ether and a fluororesin inorganic binder, 80 to 95% by weight of fluoroalkyl ether, and 5 to 20% by weight of fluororesin. It contains an inorganic binder agent.

  According to the lubricant for bottle conveyors of the present invention formed as described above, the lubricant is applied to the mounting surface of the bottles of the bottle conveyor and dried to form a dry film, thereby forming a liquid lubricant. The bottle can be smoothly transported without using the bottle, and the lubricity and stability of the bottle placement surface of the bottle conveyor can be improved.

  Since the lubricant for bottle conveyors of the present invention is configured and acts in this way, bottles can be smoothly conveyed without using a liquid lubricant, and the lubricity of the bottle placement surface of the bottle conveyor and Stability can be improved, foam can be prevented from adhering to the bottles, malfunctions of various inspection machines can be prevented, and the load on the septic tank can be reduced by not using liquid substances, and leakage of lubricant can be prevented. Eliminating the environment, the system and facilities that have been required in the past are unnecessary, making the entire device compact, and preventing bottles from being damaged.

  Hereinafter, embodiments of the lubricant for bottle conveyors of the present invention will be described.

  The lubricant for bottle conveyors of the present invention contains a fluoroalkyl ether and a fluororesin inorganic binder, preferably 80 to 95% by weight of fluoroalkyl ether and 5 to 20% by weight of fluororesin inorganic. A system binder agent.

  When the fluoroalkyl ether is less than 80% by weight and the fluororesin inorganic binder exceeds 20% by weight, the dynamic friction coefficient of the lubricant film after drying becomes large and cannot be used.

  If the fluoroalkyl ether exceeds 95% by weight and the fluororesin inorganic binder is less than 5% by weight, the dried lubricant film will not function as a lubricant.

  When the lubricant for the bottle conveyor of the present invention formed in this way is applied to at least the bottle mounting surface of the bottle conveyor in a liquid state and dried to form a dry film, a liquid such as water other than the dry film is formed. The bottle could be smoothly transported without using any lubricant, and the lubricity and stability of the bottle placement surface of the bottle conveyor could be improved.

Example 1 (friction coefficient)
The friction coefficient of the lubricant for bottle conveyors of the present invention and each of Comparative Examples 1 to 3 were measured and compared.

<Composition>
Product of the present invention: Mixture of 80% fluoroalkyl ether and 20% by weight fluororesin inorganic binder (available commercially available fluoroalkyl ether and fluororesin inorganic binder)
Comparative Example 1: Mixture obtained by diluting oleic acid 200 times with water (Oleic acid was a commercially available product)
Comparative Example 2: A mixture obtained by diluting tall oil fatty acid 200 times with water (a commercially available tall oil fatty acid was used)
Comparative Example 3: Fluororesin only (A commercially available fluororesin was used)
<Measurement result of friction coefficient>
Product of the present invention: 0.096
Comparative Example 1: 0.105
Comparative Example 2: 0.111
Comparative Example 3: 0.128

  The product of the present invention has a smaller coefficient of friction than Comparative Examples 1-3. This makes it possible to smoothly transport the bottle without overturning, even when the bottle stagnates in the middle of transportation only by the dry film without using a liquid lubricant, and when the bottle is placed on the placement surface. In addition, the bottle can be placed and transported smoothly without being overturned, and the lubricity and stability of the bottle placement surface of the bottle conveyor can be improved.

Example 2 (actual driving situation)
Pull out the top chain of the bottle conveyor used in the transport line, remove the top plate that becomes the horizontal plate, and remove the moisture and foreign matter adhering to the top rate of the target top chain using the cleaning agent. . Then, after drying the cleaning agent, the product of the present invention in Example 1 was applied evenly to the top and front surfaces of the top plate and the contact portion with the bottle by brush or spray, and the product of the present invention applied to the top plate was completely After drying, the top plate was reassembled. Thereafter, bottles such as cans and plastic bottles were placed on a bottle conveyor, and the operating conditions in the production line were observed. The results are shown in Table 1.

  As shown in Table 1, according to the product of the present invention, the bottle could be smoothly conveyed, and the lubricity and stability of the bottle placement surface of the bottle conveyor could be improved.
