You can use this below code in your controller file.

protected $session;

public function __construct(
....
\Magento\Customer\Model\Session $session
....
){
....
$this->session = $session;
....
}


public function execute(){
$lastCustomerId = $this->session->getId();
$this->session->logout()->setBeforeAuthUrl($this->_redirect->getRefererUrl())->setLastCustomerId($lastCustomerId);

/** @var \Magento\Framework\Controller\Result\Redirect $resultRedirect */
$resultRedirect = $this->resultRedirectFactory->create();
$resultRedirect->setPath('customer/account/logoutSuccess/');
return $resultRedirect;
}

Hope it maybe helpful for you.

Use Session destroy() method. It's worked for me perfectly

use Magento\Customer\Model\Session;
use Magento\Framework\App\Config\ScopeConfigInterface;
use Magento\Framework\Controller\ResultFactory;
use Magento\Framework\Message\ManagerInterface;
use Magento\Framework\Registry;
use Magento\Framework\UrlInterface;

class Controllername()
{
    //const MODULE_ENABLED = 'customerlogin/general/enable';
    protected $coreRegistry;
    protected $url;
    protected $resultFactory;
    protected $messageManager;
    protected $session;
    public function __construct(Registry $registry,
                                UrlInterface $url,
                                ManagerInterface $messageManager,
                                ScopeConfigInterface $scopeConfig,
                                Session $customerSession,
                                ResultFactory $resultFactory
    )
    {
        $this->session = $customerSession;
        $this->coreRegistry = $registry;
        $this->url = $url;
        $this->resultFactory = $resultFactory;
        $this->messageManager = $messageManager;
        $this->_scopeConfig = $scopeConfig;
    }

public function Yourfunction()
    {
            $this->messageManager->getMessages(true);
            // Adding a custom message
            $this->messageManager->addErrorMessage(__('logout successfully.'));
            // Destroy the customer session in order to redirect him to the login page
            $this->session->destroy();
            /** @var \Magento\Framework\Controller\Result\Redirect $result */
            $result = $this->resultFactory->create(ResultFactory::TYPE_REDIRECT);
            $result->setUrl($this->url->getUrl('customer/account/login'));
            return $result;
        }

You can simply destroy session to logout the customer.

/** @var Magento\Customer\Model\Session; */
$session->destroy();

And than redirect page to login page.

/** @var \Magento\Framework\Controller\Result\Redirect $result */
$result = $this->resultFactory->create(ResultFactory::TYPE_REDIRECT);
$result->setUrl($this->url->getUrl('customer/account/login'));
return $result;

I wish it will helps you.
